ITEM 1. BUSINESS

The terms “we,” “us,” “our,” “Daré” or the “Company” refer collectively to Daré Bioscience, Inc. and its wholly-owned subsidiaries, unless otherwise stated or the
context otherwise requires. All information in this report is based on our fiscal year. Unless otherwise stated, references to particular years, quarters, months or periods
refer to our fiscal years ending December 31 and the associated quarters, months and periods of those fiscal years.

Overview

We  are  a  biopharmaceutical  company  committed  to  advancing  innovative  products  for  women’s  health.  We  are  driven  by  a  mission  to  identify,  develop  and
bring to market a diverse portfolio of differentiated therapies that prioritize women's health and well-being, expand treatment options, and improve outcomes, primarily in
the areas of contraception, vaginal health, reproductive health, menopause, sexual health and fertility. Our business strategy is to in-license or otherwise acquire the
rights to differentiated product candidates in our areas of focus, some of which have existing clinical proof-of-concept data, to take those candidates through mid to late-
stage  clinical  development  or  regulatory  approval,  and  to  establish  and  leverage  strategic  collaborations  to  achieve  commercialization.  We  and  our  wholly-owned
subsidiaries operate in one business segment.

The first FDA-approved product to emerge from our portfolio of women's health product candidates is XACIATO (clindamycin phosphate) vaginal gel 2%, or
XACIATO (pronounced zah-she-AH-toe). XACIATO was approved by the FDA in December 2021 as a single-dose prescription medication for the treatment of bacterial
vaginosis  in  females  12  years  of  age  and  older.  In  March  2022,  we  entered  into  an  agreement  with  an  affiliate  of  Organon  &  Co.,  Organon  International  GmbH,  or
Organon,  which  became  fully  effective  in  June  2022,  whereby  Organon  licensed  exclusive  worldwide  rights  to  develop,  manufacture  and  commercialize  XACIATO.
Accordingly, our potential future revenue from the commercialization of XACIATO will consist of royalties based on net sales and milestone payments from Organon.
Organon commenced U.S. marketing of XACIATO in the fourth quarter of 2023.

We  began  assembling  our  diverse  portfolio  of  clinical-stage  product  candidates  and  pre-clinical  programs  in  2017  through  acquisitions,  exclusive  in-licenses
and other collaborations. Our programs target unmet needs in women's health in the areas of contraception, vaginal health, reproductive health, menopause, sexual
health  and  fertility,  and  aim  to  expand  treatment  options,  enhance  outcomes  and  improve  ease  of  use  for  women.  We  are  primarily  focused  on  progressing  the
development of our existing portfolio of product candidates. However, we also explore opportunities to expand our portfolio by leveraging assets to which we hold rights
or obtaining rights to new assets, with continued focus solely on women's health. We believe the product candidates in our portfolio offer innovative approaches that
may provide meaningful benefits over current therapeutic or contraceptive options. We evaluate potential new product candidates based on similar selection criteria as
we applied in assembling our existing portfolio. Our product candidates, if approved for commercial sale, would be physician prescribed products.

Our Strategy

Our  goal  is  to  bring  to  market  innovative  products  that  address  persistent  unmet  needs  in  women’s  health,  primarily  in  the  areas  of  contraception,  vaginal
health, reproductive health, menopause, sexual health and fertility - areas in women's health that we believe represent compelling and meaningful market opportunities
for  products  that  enhance  outcomes  and  convenience.  We  plan  to  achieve  this  goal  by  advancing  the  product  candidates  in  our  portfolio  through  mid-  to  late-stage
clinical development, and potentially regulatory approval, as well as by establishing and leveraging strategic partnerships and other collaborations to complete product
development and commercialize our products, if approved. We are primarily focused on progressing the development of our existing portfolio of product candidates.
However, we also explore opportunities to expand our portfolio through both business development activities that may result in acquiring, or acquiring access to, new
product candidates through in-licensing or other collaborative arrangements, and leveraging platform technology assets we previously acquired or in-licensed from third
parties  that  can  be  modified  with  different  active  pharmaceutical  ingredients  to  address  multiple  indications.  As  with  our  current  portfolio,  we  seek  innovations  in
women’s  health  that  have  (a)  attractive  market  opportunities  with  the  potential  to  address  an  unmet  medical  need,  including  through  new  formulations,  manners  of
application or delivery methods of well-known drug substances that result in novel, product candidates customized for women, (b) human proof-of-concept clinical data
previously generated by third parties and/or potential to utilize the FDA's 505(b)(2) pathway, and (c) potential to become a first-in-category or first-line product.

Key elements of our business strategy are as follows:

•

•

•

•

Advance clinical development of the product candidates in our portfolio through mid- to late-stage clinical development or regulatory approval. In 2023,
we continued to make important progress in the clinical development of our product candidates, including with the completion of, and positive topline
results  from  the  exploratory  Phase  2b  RESPOND  study  of  Sildenafil  Cream,  3.6%,  the  Phase  1/2  study  of  DARE-HRT1  and  the  Phase  1  study  of
DARE-PDM1,  as  well  as  FDA  clearance  of  our  investigational  new  drug,  or  IND,  application  for  DARE-VVA1  and  the  commencement  of  the  pivotal
Phase 3 study of Ovaprene.

Explore opportunities to expand our portfolio, with women’s health as our sole focus. While simultaneously advancing our current portfolio, we intend to
continue to identify other important areas of unmet need in women’s health and to explore opportunities to build our product pipeline by acquiring or in-
licensing  new  programs  or  leveraging  assets  we  previously  acquired  or  in-licensed  to  create  new  programs  that  meet  our  selection  criteria.  For
example,  in  2023,  we  entered  into  a  license  agreement  under  which  we  acquired  exclusive  rights  to  develop  and  commercialize  in  the  U.S.  an
investigational  anti-viral  vaginal  insert,  which  we  refer  to  as  DARE-CIN,  for  the  treatment  of  cervical  intraepithelial  neoplasia  and  other  human
papillomavirus (HPV)-related pathologies.

Pursue strategic collaborations to fund our business and/or enhance our development and commercialization capabilities.  We  intend  to  develop  and
maintain strategic relationships with commercial-stage companies that are leaders or emerging leaders in women’s health, as well as with other entities,
where  we  believe  such  collaborations  will  help  fund  our  business  or  accelerate  or  otherwise  improve  upon  our  clinical  development  and  regulatory
strengths and/or product manufacturing and commercialization capabilities. Examples of our efforts to date include our license agreement with Organon
to  commercialize  XACIATO,  our  license  agreement  with  Bayer  to  commercialize  Ovaprene,  if  approved  and  the  license  becomes  effective,  and  our
Cooperative  Research  and  Development  Agreement,  or  CRADA,  with  the  Eunice  Kennedy  Shriver  National  Institute  of  Child  Health  and  Human
Development, or NICHD, for the conduct of the Phase 3 clinical study of Ovaprene.

Seek non-dilutive sources of funding to support product development. We intend to advance development of our programs through a variety of means,
including  through  non-dilutive  funding.  To  date,  we  have  received  non-dilutive  funding  to  support  various  aspects  of  development  of  seven  of  our
product candidates. We intend to continue to explore grants and other forms of non-dilutive funding to support development of our product candidates.

XACIATO™

XACIATO (clindamycin phosphate) vaginal gel, a lincosamide antibacterial, received FDA approval in December 2021 for the treatment of bacterial vaginosis in

female patients 12 years of age and older.

6

XACIATO  is  our  first  and,  to  date,  only  approved  product.  We  achieved  FDA  approval  of  XACIATO  three  years  after  acquiring  rights  to  the  program.  We
commenced and completed a successful pivotal clinical study, prepared and filed a new drug application, or NDA, with the FDA and received notification from the FDA
of U.S. marketing approval, all during the COVID-19 pandemic.

In March 2022, we entered into an agreement with Organon which became fully effective in June 2022, whereby Organon licensed exclusive worldwide rights to
develop, manufacture and commercialize XACIATO. Accordingly, our potential future revenue from the commercialization of XACIATO will consist of royalties based on
net sales and milestone payments from Organon. See "Strategic Agreements for Product Commercialization" below for further discussion of the terms of our agreement
with Organon. We remained the NDA holder of XACIATO until December 2023, at which time the NDA was transferred by the FDA to Organon, and Organon assumed
all manufacturing responsibilities, regulatory and compliance matters. Organon is also responsible for commercializing, promoting, determining pricing, and negotiating
reimbursement matters related to XACIATO. See "Sales and Marketing" below for further discussion of manufacturing for XACIATO and "Government Regulation—U.S.
Government Regulation" below for discussion of applicable laws and compliance requirements. Organon commenced U.S. marketing of XACIATO in the fourth quarter
of 2023.

In  December  2023,  we  entered  into  a  royalty  interest  financing  agreement  pursuant  to  which  we  sold  an  interest  in  the  royalty  and  milestone  payments  we

receive from Organon in respect of the net sales of XACIATO by Organon. See "Royalty Interest Financing Agreement" below for a discussion of this agreement.

XACIATO  previously  received  both  Qualified  Infectious  Disease  Product  (QIDP)  and  Fast  Track  designations  from  the  FDA  for  the  treatment  of  bacterial
vaginosis  in  women.  As  a  result  of  the  QIDP  designation,  XACIATO  was  eligible  to  receive  a  five-year  extension  of  the  three  years  of  data  exclusivity  in  the  U.S.
available  to  the  product  based  on  the  submission  of  new  clinical  data  that  were  essential  to  its  approval.  The  FDA  granted  XACIATO  for  the  treatment  of  bacterial
vaginosis in female patients 12 years of age and older three years of data exclusivity, which was extended by five years, such that the data exclusivity period will expire
on December 7, 2029. XACIATO has also been designated as a reference listed drug by the FDA for purposes of future generic drug development. The data exclusivity
period should block the FDA from approving either a subsequent abbreviated NDA or 505(b)(2) NDA that relies in whole or in part on our protected clinical data. See
also  "Government  Regulation  -  U.S.  Government  Regulation-  New  Drug  Marketing  Exclusivity  under  the  Hatch-Waxman  Act  Amendments  &  GAIN  Exclusivity
Extension" below. Additionally, see the discussion of patents and patent applications related to XACIATO under "Intellectual Property—Patents" below.

Our Pipeline: Clinical-Stage Programs

Ovaprene®

We believe the need for more effective and convenient options is particularly true with contraception. While a variety of hormonal and non-hormonal options

exist, there is a notable void: an effective, short-acting, hormone-free method of contraception that does not require intervention at the time of intercourse.

Ovaprene  is  a  novel,  investigational  hormone-free  monthly  intravaginal  contraceptive  designed  to  be  worn  conveniently  over  multiple  weeks  (one  menstrual
cycle) and with the potential to achieve “typical use” contraceptive efficacy approaching that of current FDA-approved non-implanted hormonal contraceptive methods
(pills, patches and vaginal rings), which is approximately 91% typical use efficacy. Typical use contraceptive efficacy refers to the expected rate of pregnancy prevention
during the first year of actual use of a method, including sometimes using the method in a way that is not correct or not consistent. Ovaprene features a proprietary
knitted polymer barrier to physically block sperm from entering the cervical canal within a silicone-reinforced ring that releases non-hormonal agent ferrous gluconate to
impede  sperm  motility.  Unlike  current  FDA-approved  monthly  intravaginal  contraceptives,  Ovaprene  does  not  contain  hormones,  but,  consistent  with  those  monthly
intravaginal contraceptives, including Merck’s NuvaRing®, Ovaprene is designed to be a “one size fits most” monthly, self-administered product. If approved, Ovaprene
could be the first hormone-free, monthly contraceptive option for women.

7

Ovaprene is composed of both device and drug components and is considered a combination product by the FDA. There is no predicate device for Ovaprene
(i.e., there is no existing FDA-approved product that the FDA can use to compare with Ovaprene). As such, Ovaprene will be reviewed via a premarket approval, or
PMA, process and not a 510(k) premarket submission. While the regulatory process for such a novel product can require more interactions and research to support
FDA approval, the benefit is a clearly differentiated product. Ovaprene previously underwent a request for designation process with the FDA that determined that the
Center for Devices and Radiological Health, or CDRH, would lead the review of a PMA application for potential marketing approval in the U.S.

Clinical Data

In a postcoital test, or PCT, pilot clinical study conducted by the previous sponsor in 20 women and published in The Journal of Reproductive Medicine® in
2009, Ovaprene demonstrated the ability to immobilize sperm and prevent their progression into the cervical mucus. The study also demonstrated the acceptability of
the device to both partners. No colposcopic abnormalities, no significant changes in vaginal flora and no serious adverse effects were observed.

In November 2019, we announced positive topline results of our PCT clinical trial of Ovaprene (ClinicalTrials.gov ID: NCT03598088). We designed the PCT
clinical trial to assess general safety and effectiveness in preventing progressively motile sperm from reaching the cervical canal following intercourse and acceptability
of the product to the patient. The study evaluated 23 women over the course of five menstrual cycles, with each woman assessed over approximately 21 visits. Each
woman’s cervical mucus was measured at several points during the study, including a baseline measurement at menstrual cycle 1 that excluded the use of any product.
Subsequent cycles and visits included the use of a diaphragm during intercourse (menstrual cycle 2) and Ovaprene (menstrual cycles 3, 4 and 5). The primary endpoint
of the study was to evaluate changes from baseline in PCT results due to device use, as represented by the proportion of women and cycles with an average of fewer
than five progressively motile sperm (PMS) per high power field (HPF) in midcycle cervical mucus collected two to three hours after intercourse with Ovaprene in place.

Our PCT clinical trial met its primary endpoint: Ovaprene prevented the requisite number of sperm from reaching the cervix across all women and all cycles
evaluated. Specifically, in 100% of women and cycles, an average of less than five PMS per HPF were present in the midcycle cervical mucus collected two to three
hours after intercourse with Ovaprene in place. To calculate the average number of PMS, PMS were counted across each of nine HPFs and averaged. Women enrolled
in the study who completed at least one Ovaprene PCT (N=26) had a mean of 27.21 PMS/HPF in their baseline cycle when no contraception was used, a mean of 0.22
PMS/HPF in their diaphragm cycle, which was anticipated based on published studies, and a mean of 0.48 PMS/HPF in their Ovaprene PCT cycles, with a median of
zero PMS. No serious or severe adverse events were reported or observed.

PCT  clinical  trials  have  been  used  as  a  surrogate  marker  for  contraceptive  effectiveness.  Infertility  research  suggests  that  higher  rates  of  pregnancy  are
associated with PMS per HPF of from greater than one to greater than 20 PMS, and less than five PMS per HPF is considered indicative of contraceptive effectiveness.

Pivotal Phase 3 Clinical Study

In December 2023, we announced commencement of the multi-center, single arm, non-comparative, pivotal Phase 3 clinical study of Ovaprene to evaluate its
effectiveness  as  a  contraceptive  along  with  its  safety  and  acceptability  (ClinicalTrials.gov  ID:  NCT06127199).  The  study  aims  to  enroll  sufficient  participants  across
approximately  20  study  sites  in  the  U.S.  to  have  approximately  250  participants  complete  approximately  12  months  (13  menstrual  cycles)  of  use.  Based  on  typical
dropout  rates  for  contraceptive  efficacy  studies,  we  will  seek  to  enroll  more  than  double  the  number  of  subjects  we  target  to  complete  13  menstrual  cycles  of  use.
Before  commencing  the  study,  we  worked  with  our  collaborators  at  the  National  Institutes  of  Health,  or  NIH,  and  at  Bayer  to  review  and  implement  study  design
considerations provided by the FDA with its Investigational Device Exemption, or IDE, approval letter, which we believe will further position the Phase 3 study to collect
safety and effectiveness data to enable the preparation of, and to support the submission of, a PMA application for Ovaprene. The primary objective of the study is to
assess the typical use pregnancy rate over 13 menstrual cycles, or the estimated Pearl Index for Ovaprene. Secondary objectives are to assess Ovaprene's 13-cycle
use cumulative pregnancy rate, safety, acceptability, product fit/ease of use, and assessments of vaginal health. If successful, we expect the study to support a PMA
application to the FDA, as well as regulatory filings in Europe and other countries worldwide, to allow for marketing approvals of Ovaprene.

The  Phase  3  study  is  being  conducted  under  our  Cooperative  Research  and  Development  Agreement,  or  CRADA,  with  the  U.S.  Department  of  Health  and
Human  Services,  as  represented  by  the  Eunice  Kennedy  Shriver  National  Institute  of  Child  Health  and  Human  Development,  or  NICHD,  part  of  the  NIH,  and  within
NICHD’s Contraceptive Clinical Trial Network. We and NICHD will each provide medical oversight and final data review and analysis for the study and will work together
to prepare the final report of the results of the study. We are responsible for providing clinical supplies of Ovaprene, coordinating interactions with the FDA, preparing
and submitting supportive regulatory documentation, and providing a total of $5.5 million to NICHD to be applied toward the costs of conducting the Phase 3 study, $5.0
million of which has been paid. NICHD is responsible for the other costs related to the conduct of the Phase 3 study and for managing the payment of expenses to the
contract  research  organization  for  the  study,  the  clinical  sites,  and  other  parties  involved  with  the  study.  We  expect  to  make  the  remaining  $0.5  million  payment  to
NICHD in the third quarter of 2024. In the future, depending on the duration of the enrollment period and number of subjects enrolled in the Phase 3 study, there may be
costs associated with the study that are not reflected in the current budget under the CRADA, in which case, we and NICHD would discuss the mechanism to potentially
provide for additional future payments by us in support of the Phase 3 study. We do not expect any such potential additional amounts to be payable in 2024.

In  addition  to  the  CRADA,  we  are  collaborating  with  ADVA-Tec,  Inc.,  or  ADVA-Tec,  and  Bayer  HealthCare  LLC,  or  Bayer,  for  the  development  and
commercialization  of  Ovaprene  as  part  of  two  strategic  collaborations  announced  in  March  2017  and  January  2020,  respectively.  See  "Strategic  Agreements  for
Pipeline Development" and "Strategic Agreements for Product Commercialization" below for discussion of the terms of each collaboration.

Sildenafil Cream, 3.6%

While numerous pharmaceutical products have been developed and approved to treat erectile dysfunction in men, women continue to lack effective options for
female  sexual  arousal  disorder,  or  FSAD,  the  most  analogous  condition  of  the  various  types  of  female  sexual  dysfunction  disorders.  We  are  developing  Sildenafil
Cream, 3.6%, or Sildenafil Cream, an investigational proprietary cream formulation of sildenafil, a phosphodiesterase-5 inhibitor and the active ingredient in the male
erectile  dysfunction  drug  Viagra®,  for  topical  administration  to  the  female  genitalia  for  treatment  of  FSAD.  Today,  there  are  no  treatments  approved  by  the  FDA  for
FSAD  and  thus,  there  are  no  efficacy  endpoints  that  have  been  previously  validated  in  a  Phase  3  pivotal  study  for  potential  treatments  for  FSAD.  Our  Phase  2b
RESPOND clinical study of Sildenafil Cream, which is discussed further below, was a first of its kind Phase 2b clinical study that included patient reported outcome
(PRO)  instruments  to  screen  eligible  women  and  a  number  of  primary,  secondary,  and  exploratory  PRO  assessments  to  measure  improvement  in  localized  genital
sensations of arousal and reduction in the distress that women experience with FSAD. We are developing the study design for Phase 3 clinical studies of Sildenafil
Cream with ongoing feedback from the FDA coming out of our end-of-Phase 2 meeting with the FDA held in late 2023. We expect the FDA to complete its review of the
Phase  2b  RESPOND  clinical  study  data  and  provide  comments  within  the  second  quarter  of  2024  on  the  proposed  primary  and  secondary  PRO  endpoints  for  the
planned Phase 3 pivotal trials of Sildenafil Cream to support potential product registration and labeling. We plan to leverage the existing data and established safety
profile of sildenafil and the Viagra® brand to utilize the FDA’s 505(b)(2) pathway to obtain marketing approval of Sildenafil Cream in the U.S. for the treatment of women
suffering from FSAD. If approved, Sildenafil Cream could be the first FDA-approved FSAD treatment option for women.

FSAD, as described in the Diagnostic and Statistical Manual of Mental Disorders 4th Edition Text Revision ("DSM IV TR"), is a condition characterized primarily
by a persistent or recurrent inability to attain or maintain sufficient genital arousal (an adequate lubrication-swelling response) during sexual activity, frequently resulting
in distress or interpersonal difficulty. This is distinct from hypoactive sexual desire disorder (HSDD) in women (also described in DSM IV TR), which is characterized
primarily by lack or absence of sexual fantasies and desire for sexual activity (also commonly referred to as low libido). As with erectile dysfunction in men, FSAD in
women is associated with insufficient blood flow to the genitalia. Sildenafil Cream is designed to facilitate vasodilation and increase genital blood flow, and, as a result,
to provide improvements in the female genital arousal response, while avoiding systemic side effects observed with oral formulations of sildenafil.

Clinical Data

In a Phase 1 clinical study of three escalating doses of topical sildenafil cream (1 g cream with 35 mg sildenafil; 2 g cream with 71 mg sildenafil; and 4 g cream
with  142  mg  sildenafil)  in  20  healthy  postmenopausal  women  using  a  crossover  study  design,  topical  sildenafil  cream  demonstrated  significantly  lower  systemic
exposure to sildenafil compared to a 50 mg oral sildenafil dose, and topical sildenafil cream was safe and well tolerated at clinically relevant doses (1-2 g cream). Study
subjects reported favorable product characteristics: easy to use and readily absorbed.

9

In  a  Phase  2a,  single  center,  single-dose,  double-blind,  placebo-controlled,  2-way  crossover  study,  women  with  FSAD,  ages  21  to  60,  received  a  single  2  g
dose of Sildenafil Cream. Of the 35 women enrolled, 31 (15 premenopausal and 16 postmenopausal) completed the study. The primary objective was to evaluate the
efficacy  of  Sildenafil  Cream  compared  to  placebo  cream  assessed  by  participant-reported  levels  of  subjective  cognitive  sexual  arousal  and  by  physiological  genital
arousal  response.  Sildenafil  Cream  demonstrated  increases  in  measurable  blood  flow  to  the  genital  tissue  compared  to  placebo  (mean  change  in  vaginal  pulse
amplitude analysis) using a vaginal photoplethysmograph approximately 30 minutes post-dosing.

A  Phase  1,  single-dose,  double-blind,  placebo-controlled,  two-way  crossover  study  to  evaluate  the  feasibility  of  using  thermography  to  assess  the
pharmacodynamics  (PD)  of  Sildenafil  Cream  in  normal  healthy  women  was  conducted  at  a  single  center.  During  the  thermography  study,  genital  temperature,  a
surrogate for genital blood flow, was captured and recorded utilizing an infrared camera capable of detecting heat patterns from blood flow in body tissues. The study,
which  was  designed  to  evaluate  up  to  10  subjects,  achieved  the  study  objectives  based  on  a  planned  interim  analysis  of  the  first  six  completed  subjects,  and  thus
additional subjects were not enrolled. In this study, Sildenafil Cream demonstrated significantly greater increases in genital temperature compared to placebo cream,
indicating  a  positive  impact  on  genital  blood  flow  during  the  30-minute  post-dosing  testing  session,  with  statistical  separation  from  placebo  cream  within  the  first  15
minutes after dosing. Additionally, significantly greater self-reported arousal responses were reported during Sildenafil Cream visits compared to placebo cream visits.

In  2019,  as  part  of  our  exploratory  Phase  2b  clinical  program  for  Sildenafil  Cream,  we  completed  a  non-interventional  study,  or  the  content  validity  study,
designed to identify and document the genital arousal symptoms that are most important and relevant to women with FSAD. Participants who met the eligibility criteria
participated  in  one-on-one,  in-depth  interviews  conducted  by  subject  matter  experts  in  the  field  of  clinical  outcome  assessments  and  female  sexual  medicine.  The
findings of that study helped facilitate alignment with the FDA on acceptable efficacy endpoints in our exploratory Phase 2b clinical study and future Phase 3 program,
including  with  respect  to  the  patient  reported  outcome,  or  PRO,  instruments  to  be  used  to  screen  eligible  patients  with  FSAD  and  to  measure  achievement  of  the
primary efficacy endpoint in the Phase 2b study.

In  April  2023,  we  initiated  subject  enrollment  in  a  Phase  1,  single-dose,  double-blind,  placebo-controlled,  3-way  crossover  clinical  study  of  Sildenafil  Cream
using thermography to assess the PD and pharmacokinetic (PK) characterization of Sildenafil Cream. The study was closed in March 2024. Sildenafil Cream was safe
and well tolerated in the study. Data from the study will expand our existing clinical and nonclinical data for Sildenafil Cream and are expected to support the ongoing
development of Sildenafil Cream as a potential treatment for FSAD.

In June 2023, we announced topline results from our exploratory Phase 2b RESPOND clinical study of Sildenafil Cream in premenopausal women with FSAD,
and in July and November 2023, we announced additional findings based on further analyses of data from the study. In February 2024, we presented additional findings
from the study at the Annual Meeting of the International Society for the Study of Women's Sexual Health. During the multi-center, double-blind, randomized, placebo-
controlled  study,  subjects  used  Sildenafil  Cream  and  placebo  cream  in  their  home  setting  over  12  weeks  following  a  4-week  non-drug  run-in  period  and  a  4-week,
single-blind placebo run-in period. A total of 252 subjects were enrolled in the 4-week single-blind placebo run-in period and a total of 200 subjects were randomized to
the  12-week  double-blind  dosing  period.  A  total  of  seven  subjects  were  randomized  but  not  treated  in  the  double-blind  dosing  period.  In  the  intent  to  treat  (ITT)
population, 99 subjects were randomized to the Sildenafil Cream group and 94 subjects were randomized to the placebo cream group. The study did not meet its co-
primary or secondary endpoints, which were measured based on the ITT population. However, subjects in the Sildenafil Cream group showed improvements in multiple
pre-specified exploratory endpoints that evaluated various aspects of the sexual experience, and we view the study results as positive and enabling of advancement of
Sildenafil Cream into Phase 3 clinical development, which was confirmed by successful completion of our end-of-Phase 2 meeting with the FDA. The RESPOND study
was a first of its kind Phase 2b clinical study that enabled us to identify a subgroup of patients who are most likely to benefit from Sildenafil Cream therapy and achieve
meaningful  improvement  in  their  FSAD  symptoms.  Based  on  post  hoc  analyses,  in  a  subgroup  of  study  subjects  consisting  of  healthy  premenopausal  women  with
FSAD, including those who suffered from a lack of sexual desire due to their decreased arousal, Sildenafil Cream demonstrated improved arousal sensation, desire,
orgasm, as well as reduced stress, guilt, and embarrassment about the sexual dysfunction.

End-of-Phase 2 Meeting and Phase 3 Program

In January 2024, we announced the successful completion of an end-of-Phase 2 meeting with the FDA. We and the FDA aligned on key elements of the Phase
3 program to support an NDA filing, including confirming that FSAD is acceptable as an indication, the clinical trials can be conducted in a premenopausal FSAD-only
population,

10

and 12-weeks of blinded treatment to assess efficacy may be acceptable, provided that the trials are adequately powered for efficacy assessment. This is a shorter
period of blinded treatment than the 24 weeks recommended in the FDA's 2016 draft guidance for industry on developing drugs for the treatment of low sexual interest,
desire  and/or  arousal  in  women.  Within  the  second  quarter  of  2024,  we  expect  additional  feedback  from  the  FDA  on  our  proposed  primary  and  secondary  patient
reported outcome endpoints for the Phase 3 pivotal trials of Sildenafil Cream, as well as additional information on data that may be needed in an NDA submission to
appropriately qualify any ingredient (other than sildenafil) for the vaginal route of administration. We have also requested clarification on the safety database (size and
duration exposure) that the FDA will require for an NDA submission.

We believe FSAD is an area of significant unmet need and that the improvements demonstrated in the Phase 2b RESPOND study in the patient population we
plan to study in the Phase 3 program provided an important step towards advancing development of Sildenafil Cream for this challenging condition. We continue to
work toward finalizing the plan for Phase 3 clinical development of Sildenafil Cream.

We are developing Sildenafil Cream with Strategic Science & Technologies-D LLC and Strategic Science & Technologies, LLC (which we refer to collectively as
SST) under our license and collaboration agreement announced in February 2018. See “Strategic Agreements for Pipeline Development” below for discussion of the
terms of this collaboration.

DARE-HRT1

DARE-HRT1  is  a  unique  intravaginal  ring,  or  IVR,  designed  to  deliver  bio-identical  17β-estradiol  and  bio-identical  progesterone  continuously  over  a  28-day
period  as  part  of  a  menopausal  hormone  therapy  regimen.  The  IVR  technology  used  in  DARE-HRT1  was  developed  by  Dr.  Robert  Langer  from  the  Massachusetts
Institute  of  Technology  and  Dr.  William  Crowley  from  Massachusetts  General  Hospital  and  Harvard  Medical  School.  Unlike  other  vaginal  ring  technologies,  ours  is
designed  to  release  drugs  via  a  solid  ethylene  vinyl  acetate  polymer  matrix  without  the  need  for  a  membrane  or  reservoir  to  contain  the  active  drug  or  control  the
release,  allowing  for  sustained  drug  delivery  over  time  periods  ranging  from  weeks  to  months.  Hormone  therapy  is  considered  the  most  effective  treatment  for
vasomotor symptoms, or VMS, commonly referred to as hot flashes, and the genitourinary syndrome of menopause, and it has been shown to prevent bone loss and
fracture.

Following clinical development, we intend to leverage the large body of existing safety and efficacy data on estradiol and progesterone, the active ingredients in
DARE-HRT1,  to  utilize  the  FDA's  505(b)(2)  pathway  to  obtain  marketing  approval  in  the  U.S.  of  DARE-HRT1  for  the  treatment  of  moderate-to-severe  VMS  due  to
menopause in women with intact uteri. Based on pre-IND communications with the FDA and the topline PK data from our Phase 1/2 clinical trial of DARE-HRT1, which
is discussed below, we believe FDA approval of DARE-HRT1 for that indication is achievable via the FDA's 505(b)(2) pathway supported by a single, placebo-controlled
Phase 3 clinical trial of DARE-HRT1, with safety evaluations out to 12 months, and a scientifically justified PK “bridge” (via a relative bioavailability trial) between DARE-
HRT1 and the selected listed estradiol and progesterone drugs. We are conducting activities necessary to enable submission of an IND application to the FDA for a
pivotal Phase 3 clinical study of DARE-HRT1. We do not plan to conduct the Phase 3 study until after we secure additional capital.

There  are  currently  no  FDA-approved  IVRs  that  deliver  bio-identical  progesterone  in  combination  with  bio-identical  estradiol.  As  such,  DARE-HRT1  has  the
potential to be a first-in-category product that offers monthly convenience for women, and non-oral concurrent dosing of bio-identical progesterone in combination with
bio-identical estradiol.

Clinical Data

In January 2023, data from our Phase 1 clinical trial of DARE-HRT1 were published in Menopause: The Journal of The North American Menopause Society, or
the Menopause journal, in an article entitled, “Evaluation of 28-day estradiol and progesterone vaginal rings in a phase 1 clinical pharmacokinetic study.” We previously
announced positive topline results from the study in June 2021. The randomized, open-label, three-arm, parallel group trial evaluated the PK and safety of DARE-HRT1
in approximately 30 healthy, postmenopausal women with intact uteri, and was conducted by our wholly-owned Australian subsidiary at two specialty women's health
sites in Australia. Women in the first arm received one IVR designed to release 17β-estradiol (E2) at a rate of 80 μg/d and progesterone (P4) at 4 mg/d, or the 80/4 IVR.
Women in the second arm received one IVR designed to release E2 at a rate of 160 μg/d and P4 at 8 mg/d, or the 160/8 IVR. Women in the third arm received oral
Estrofem® (1 mg E2) and oral Prometrium® (100 mg P4) both daily for 29 days. The primary objective of the study was to describe the PK parameters of the 80/4 IVR
and the 160/8 IVR. Secondary endpoints of the study were to assess the safety and tolerability of the IVRs and compare the systemic exposure of E2, estrone, and P4
in the IVR groups with the oral group. Blood samples were taken predose then intensively over the first day (Day 1) and periodically thereafter over the remaining 27
days. After removal of the IVRs on the morning of Day 29, intensive samples were collected. Similar procedures were conducted with women enrolled in the oral group.

The journal article concluded that the 80/4 IVR and the 160/8 IVR gave similar steady-state concentrations of E2 as seen with drug products approved by the
FDA for treatment of VMS and genitourinary symptoms of menopause, and that the E2 concentrations of the study support the potential of DARE-HRT1 as a new option
for  hormone  therapy  for  treatment  of  VMS  and  vaginal  symptoms  associated  with  menopause.  The  IVRs  were  well  tolerated,  and  no  serious  adverse  events  were
reported.

DARE-HRT1 has also been evaluated in a Phase 1/2 clinical trial conducted by our wholly owned subsidiary in Australia. The randomized, open-label, two-arm,
parallel group Phase 1/2 study of DARE-HRT1 was designed to evaluate the PK of the same two versions of DARE-HRT1 as were evaluated in our earlier Phase 1
clinical study, the 80/4 IVR and the 160/8 IVR, in approximately 20 healthy, postmenopausal women with intact uteri. In the study, women were randomized (1:1) to
either the 80/4 IVR or the 160/8 IVR and used DARE-HRT1 for three 28-day cycles, inserting a new IVR monthly. The study also collected safety, usability, acceptability
and symptom-relief data, including VMS as well as the vaginal symptoms of menopause. Preliminary genitourinary syndrome of menopause (GSM) treatment efficacy
was estimated by measuring changes from baseline in vaginal pH, vaginal maturation index (VMI), and changes in the severity of GSM symptoms. Preliminary systemic
VMS  efficacy  was  measured  by  changes  in  responses  to  the  Menopause-Specific  Quality  of  Life  (MENQOL)  questionnaire.  Acceptability  was  assessed  by  product
experience surveys.

In 2023, data from the Phase 1/2 study of DARE-HRT1 were published in the Menopause journal in articles entitled, “A phase 1/2, open-label, parallel group
study to evaluate the safety and pharmacokinetics of DARE-HRT1 (80 μg estradiol/4 mg progesterone and 160 μg estradiol/8 mg progesterone intravaginal rings) over
12  weeks  in  healthy  postmenopausal  women”  (Menopause  30(8):p  817-823,  August  2023)  and  “A  phase  1/2,  open-label,  parallel  group  study  to  evaluate  the
preliminary  efficacy  and  usability  of  DARE-HRT1  (80  μg  estradiol/4  mg  progesterone  and  160  μg  estradiol/8  mg  progesterone  intravaginal  rings)  over  12  weeks  in
healthy postmenopausal women” (Menopause 30(9):p 940-946, September 2023).The first article (Menopause 30(8):p 817-823, August 2023) found that both versions
of DARE-HRT1 evaluated in the Phase 1/2 study were safe and released E2 in systemic concentrations, which were in the low, normal premenopausal range and that
systemic P4 concentrations predict endometrial protection. All treatment emergent adverse events were mild or moderate and were distributed similarly among the 80/4
IVR and the 160/8 IVR users. The second article (Menopause 30(9):p 940-946, September 2023) found that (a) preliminary local GSM treatment efficacy was supported
by significant decreases in vaginal pH and percentage (%) parabasal cells, and significant increases in the overall VMI and % superficial cells for both DARE-HRT1
groups (all P values <0.01) and (b) preliminary VMS efficacy was supported by significant decreases in all domains of the MENQOL questionnaire from baseline for
both dosing groups (all P values <0.01). Both articles concluded that data from the Phase 1/2 study support further development of DARE-HRT1 for the treatment of
menopausal symptoms.

We  are  developing  DARE-HRT1  under  our  license  agreement  with  Catalent  JNP,  Inc.  See  “Strategic  Agreements  for  Pipeline  Development”  below  for

discussion of the terms of that agreement.

DARE-VVA1

DARE-VVA1  is  a  proprietary  investigational  formulation  of  tamoxifen  for  intravaginal  administration.  We  are  developing  DARE-VVA1  as  a  hormone-free
alternative  to  estrogen-based  therapies  for  the  treatment  of  moderate-to-severe  dyspareunia,  or  pain  during  sexual  intercourse,  a  symptom  of  vulvar  and  vaginal
atrophy, or VVA, associated with menopause. Tamoxifen is a well-known and well-characterized selective estrogen receptor modulator, or SERM. Tamoxifen has unique
properties  that  produce  different  effects  (estrogen  agonist  or  estrogen  antagonist)  in  different  types  of  tissues.  In  breast  tissue,  tamoxifen  acts  as  an  estrogen
antagonist, meaning that it can inhibit estrogen's effect and hence why it may be effective in treating hormone-receptor positive (HR+) breast cancer. However, in other
tissue, including vaginal tissue, tamoxifen has been reported to elicit an estrogen-like response. This has the potential to have a favorable effect on vaginal cytology.
VVA  is  an  inflammation  and  thinning  of  the  vaginal  epithelium  due  to  chronic  hypo-estrogenism,  which  is  the  reduction  in  levels  of  circulating  estrogen.  Typical
symptoms include vaginal dryness, itching and burning, and dyspareunia. VVA is a common condition in postmenopausal women and women with, or with a history of,
HR+ breast cancer who received anti-cancer therapy. The prevalence of VVA in postmenopausal women is over 50% and survey data indicate only 56% of women
experiencing menopausal vaginal changes discuss these symptoms with healthcare professionals, indicating that the syndrome is often underdiagnosed. Commonly
used therapies for VVA are estrogen-based and are often contraindicated in HR+ breast cancer patients, or patients with a genetic predisposition or history of familial
disease, because of the concern that estrogen use will promote recurrence or occurrence of disease. We believe there is a clear unmet medical need for an effective
non-hormonal treatment for VVA.

In December 2023, we announced FDA clearance of our IND application for DARE-VVA1, which was supported by results from our Phase 1/2 clinical study of
DARE-VVA1 (discussed below), and we are planning for a Phase 2 randomized, double-blinded, placebo-controlled, dose-finding clinical study of DARE-VVA1. We do
not plan to conduct the Phase 2 study until after we secure additional capital. At the conclusion of our development program, if successful, we intend to leverage the
existing safety and efficacy data for tamoxifen to utilize the FDA’s 505(b)(2) pathway to obtain marketing approval of DARE-VVA1 in the U.S.

Clinical Data

An exploratory study of vaginal administration of tamoxifen in four healthy postmenopausal women diagnosed with VVA published in Clinical and Experimental
Obstetrics  &  Gynecology  demonstrated  that  tamoxifen  self-administered  intravaginally  for  three  months  clinically  benefited  women  with  symptoms  of  VVA  without
significant  systemic  absorption  of  the  study  drug.  In  the  open-label  prospective  cohort  study  with  no  placebo  arm,  participants  were  instructed  to  self-administer  a
vaginal suppository containing tamoxifen (20 mg) daily for one week and twice weekly for three months. The study treatment was effective in reducing vaginal pH and
vaginal  dryness.  When  measured  after  eight  weeks  on  the  study  treatment,  serum  tamoxifen  levels  were  negligible,  5.8  ng/ml  (median),  with  a  range  of  1.0  to  10.0
ng/ml. In comparison, after three months of once daily administration of oral dose of 20-mg tamoxifen, Nolvadex® (tamoxifen citrate) tablets, the average steady state
plasma concentration of tamoxifen is 122 ng/ml (range of 71 to 183 ng/ml).

DARE-VVA1 has also been evaluated in a Phase 1/2 clinical study conducted by our wholly-owned subsidiary in Australia. In November 2022, we announced
topline results from of our Phase 1/2 clinical study of DARE-VVA1 conducted by our wholly-owned subsidiary in Australia. The randomized, multi-center, double-blind,
parallel-arm, placebo-controlled, dose-ranging study enrolled 17 postmenopausal women with moderate-to-severe VVA and evaluated the safety, tolerability, plasma PK
and pharmacodynamics (PD) of DARE-VVA1. The age of the 17 study participants ranged from 49 to 68 years, with an average age of 60.9 years. Participants were
randomly allocated to one of five treatment groups (approximately four participants per group) that evaluated four dose levels of DARE-VVA1 (1 mg, 5 mg, 10 mg, and
20 mg tamoxifen) and a placebo. Following a screening visit, DARE-VVA1 was self-administered by study participants intravaginally once a day for the first two weeks,
and then twice a week for the following six weeks for a total treatment period of 56 days. In each treatment group, participants had serial blood sampling for PK analysis
and underwent safety evaluations and preliminary assessments of effectiveness. Following the completion of the treatment period, participants attended a safety follow-
up visit. Fourteen participants completed the study. The primary endpoints of the study evaluated the safety and tolerability of DARE-VVA1 by vaginal administration
and determined the plasma PK of DARE-VVA1 after intravaginal application. Secondary endpoints evaluated preliminary efficacy and PD of DARE-VVA1 in terms of the
most bothersome vaginal symptom and changes in vaginal cytology and pH.

In 2023, data from our Phase 1/2 study of DARE-VVA1 were published in Climacteric, the official journal of the International Menopause Society, in an article

entitled, “Pharmacokinetics, safety and preliminary pharmacodynamic evaluation of DARE-VVA1: a soft gelatin capsule containing tamoxifen for the treatment of

vulvovaginal atrophy.” The article concluded that DARE-VVA1 was safe and resulted in minimal systemic exposure to tamoxifen. Adverse events were mild to moderate
in severity and distributed similarly among the DARE-VVA1 and placebo groups. Plasma tamoxifen concentrations were highest among women using DARE-VVA1 20
mg, but the maximum mean (standard deviation) plasma tamoxifen concentrations on day 1 and day 56 of the treatment period were less than 14% of those measured
after one oral tamoxifen dose. The article also concluded that preliminary efficacy data support further development of DARE-VVA1. The article found that DARE-VVA1
users had significant decreases from pre-treatment baseline in vaginal pH and proportion of vaginal parabasal cells (p = 0.04 for both endpoints). Women randomized
to use DARE-VVA1 10 mg or DARE-VVA1 20 mg experienced the largest treatment impact. The severity of vaginal dryness and dyspareunia decreased significantly
from baseline with DARE-VVA1 use (p = 0.02 for both endpoints).

We acquired the DARE-VVA1 program through our acquisition of Pear Tree Pharmaceuticals in 2018. See "Strategic Agreements for Pipeline Development"

below for discussion of that merger agreement.

DARE-CIN

DARE-CIN (formerly referred to as R-131-2) is an investigational, proprietary fixed-dose formulation of lopinavir and ritonavir in a soft gel vaginal insert, which
we  plan  to  develop  for  the  treatment  of  cervical  intraepithelial  neoplasia,  or  CIN  (also  known  as  cervical  dysplasia),  and  other  HPV-related  pathologies.  CIN  is  a
precancerous condition in women strongly linked to HPV infection, the most common sexually transmitted infection in the U.S. Disease severity is classified on a scale
from one to three based on how much epithelial tissue in the cervix has abnormal cells. There is no FDA-approved non-surgical pharmaceutical intervention to treat
CIN2 or CIN3 (collectively referred to as CIN2+). Current surgical procedures to treat cervical dysplasia are invasive and can adversely impact future pregnancies. We
believe a non-surgical pharmaceutical approach could provide women with an important alternative to surgical procedures to treat cervical dysplasia.

We are conducting limited activities to support an IND submission to the FDA to enable Phase 2 clinical development of DARE-CIN in the United States. We do

not plan to conduct the Phase 2 study until after we secure additional capital.

Clinical Data

DARE-CIN was previously evaluated in a proof-of-concept clinical study and the results demonstrated its potential as a self-applied therapy for HPV infection

and related cervical lesions. DARE-CIN was also previously evaluated in a Phase 1 clinical study to assess PK.

We  are  developing  DARE-CIN  under  our  license  agreement  with  Douglas  Pharmaceuticals,  Limited.  See  "Strategic  Agreements  for  Pipeline  Development"

below for discussion of the terms of that agreement.

DARE-PDM1

DARE-PDM1  is  an  investigational  proprietary  hydrogel  formulation  of  diclofenac  for  vaginal  administration  designed  to  treat  primary  dysmenorrhea.  DARE-
PDM1 utilizes our proprietary hydrogel technology to vaginally deliver the active pharmaceutical ingredient, diclofenac, a nonsteroidal anti-inflammatory drug (NSAID),
in a novel way for the treatment of primary dysmenorrhea. Primary dysmenorrhea is defined as painful menstruation in girls and women with normal pelvic anatomy,
typically described as cramping pain in the low back or lower abdomen before or during the menstrual period. Oral NSAIDs, such as diclofenac, are often recommended
for temporary relief from the painful symptoms of primary dysmenorrhea. Because there are currently no FDA-approved vaginal diclofenac treatment options for primary
dysmenorrhea, DARE-PDM1 has the potential to be a first-in-category product, delivering diclofenac in a convenient vaginal format that may extend the duration of pain
relief  and  reduce  the  risks  associated  with  the  oral  delivery  of  NSAIDs.  According  to  the  American  College  of  Obstetricians  and  Gynecologists’  Committee  on
Adolescent  Health  Care,  dysmenorrhea  is  the  most  common  menstrual  symptom  among  adolescent  girls  and  young  women,  and  most  adolescents  experiencing
dysmenorrhea have primary dysmenorrhea. Prevalence rates of dysmenorrhea vary but range from 50% to 90%.

Clinical Data

DARE-PDM1 has been evaluated in a Phase 1 clinical study, DARE-PDM1-001, conducted by our wholly-owned subsidiary in Australia. DARE-PDM1-001 was
a  multi-center,  randomized,  placebo-controlled,  double-blind,  three-arm  parallel  group  study  that  enrolled  approximately  42  healthy,  premenopausal  women  with
symptomatic primary dysmenorrhea. This study was designed to assess the systemic (plasma) and local mucosal (vaginal fluid) diclofenac PK and safety after a single
dose and during three daily doses of vaginally administered DARE-PDM1, given in two different strengths (1% or 3% diclofenac in 2.5 mL of hydrogel) versus placebo
(vaginal hydrogel, no active ingredient). The study also assessed, as an exploratory endpoint, the preliminary dysmenorrhea treatment efficacy of DARE-PDM1, when
dosed in three daily doses at the onset of dysmenorrhea symptoms, compared to a no-treatment, baseline, control cycle. The study observation period encompassed
approximately three menstrual cycles.

In  December  2023,  we  announced  topline  data  from  the  DARE-PDM1-001  study.  The  topline  data  indicate  that  the  study  treatment  was  well-tolerated,  and
treatment  emergent  adverse  events  profiles  were  comparable  between  the  DARE-PDM1  treatment  groups  and  the  placebo  group.  All  adverse  events  were  mild  or
moderate; most adverse events (85%) were mild. There were no early discontinuations due to an adverse event, and no serious adverse events were reported.

The vaginal fluid PK results exhibited dose proportionality for the 1% and 3% diclofenac strengths of the DARE-PDM1 study treatment. Additionally, the vaginal
fluid  PK  results  demonstrated  that  for  approximately  75%  (21/28)  of  the  women  in  the  DARE-PDM1  treatment  groups  the  product  was  retained  in  the  vaginal  canal
through 24 hours. The plasma PK results similarly exhibited dose proportionality for the 1% and 3% diclofenac strengths of the DARE-PDM1 study treatment. Plasma
levels  of  diclofenac  were  at  peak  plasma  concentrations  within  3-4  hours  for  both  diclofenac  strengths  of  the  DARE-PDM1  study  treatment,  and  diclofenac  was  no
longer  detectable  in  the  plasma  by  48  hours  post  study  treatment  for  the  majority  of  subjects  in  the  study.  The  plasma  PK  results  for  both  DARE-PDM1  treatment
groups indicate that vaginal dosing could result in systemic exposure which is approximately 1,000 times less than that seen from oral use of diclofenac.

The  exploratory  endpoint  that  evaluated  the  preliminary  efficacy  of  DARE-PDM1  versus  placebo  in  reducing  dysmenorrhea-associated  pain  showed  a
promising signal, with a statistically significant decrease in pelvic/vaginal and lower back pain scores in the 1% diclofenac DARE-PDM1 treatment group compared to
the placebo group, as well as a decrease in pain scores in the 3% diclofenac DARE-PDM1 treatment group. Additionally, while most participants used at least one non-
pharmacologic pain relief method (e.g., heating pad) for dysmenorrhea-associated pain during the no-treatment, baseline, control cycle, the proportion of participants
who used at least one non-pharmacologic pain relief method for dysmenorrhea-associated pain decreased significantly in the DARE-PDM1 treatment groups during the
dosing period, but not in the placebo group. There was no difference in the exploratory assessment of frequency of use of rescue medications in the treatment phase
between the three groups.

We believe the topline results of the Phase 1 study support continued clinical development of DARE-PDM1 as a treatment for primary dysmenorrhea. At the
conclusion of the development program, if successful, we intend to leverage the existing safety and efficacy data for diclofenac to utilize the FDA's 505(b)(2) pathway to
obtain marketing approval of DARE-PDM1 in the U.S.

15

We  are  developing  DARE-PDM1  under  our  agreements  with  TriLogic  Pharma,  LLC,  MilanaPharm  LLC  and  Hammock  Pharmaceuticals,  Inc.  See  "Strategic

Agreements for Pipeline Development" below for discussion of those agreements.

DARE-204 and DARE-214

DARE-204 and DARE-214 are formulations of etonogestrel designed to provide contraception over 6-month and 12-month periods, respectively. These product
candidates are being developed as a sub-cutaneous injectable, longer-acting, reversible method of contraception with a more predictable return to fertility. We plan to
conduct  Phase  1  clinical  studies  of  DARE-204  and  DARE-214  in  Australia  through  our  wholly-owned  subsidiary  in  Australia.  Additional  manufacturing  activities  are
necessary  to  commence  the  Phase  1  studies  and  these  activities  have  not  commenced.  If  we  exercise  our  option  and  enter  into  an  exclusive  worldwide  license
agreement for DARE-204 and/or DARE-214, at the conclusion of these development programs, if successful, we intend to leverage the existing safety and efficacy data
for etonogestrel to utilize the FDA's 505(b)(2) pathway to obtain marketing approval in the U.S.

We are developing DARE-204 and DARE-214 under our development and option agreement with Adare Pharmaceuticals USA, Inc. See "Strategic Agreements

for Pipeline Development" below for discussion of the terms of that agreement.

DARE-FRT1 and DARE-PTB1

DARE-FRT1  and  DARE-PTB1  are  IVRs  designed  to  release  bio-identical  progesterone  continuously  for  up  to  14  days.  DARE-FRT1  is  being  developed  for
luteal  phase  support  as  part  of  an  in  vitro  fertilization,  or  IVF,  treatment  plan.  DARE-PTB1  is  being  developed  for  the  prevention  of  preterm  birth.  DARE-FRT1  and
DARE-PTB1 use the same IVR technology platform as DARE-HRT1. We are conducting development activities to support IND submissions and Phase 1 clinical studies
of these product candidates. We do not plan to conduct the Phase 1 studies until after we secure additional capital. At the conclusion of these development programs, if
successful, we intend to leverage the existing safety and efficacy data for progesterone to utilize the FDA’s 505(b)(2) pathway to obtain marketing approval of DARE-
FRT1 and DARE-PTB1 in the U.S.

We are developing DARE-FRT1 and DARE-PTB1 under our license agreement with Catalent JNP, Inc. See "Strategic Agreements for Pipeline Development"

below for discussion of the terms of that agreement.

Our Pipeline: Pre-Clinical Stage Programs

Our pre-clinical stage programs are:

• DARE-LARC1,  a  contraceptive  implant  delivering  levonorgestrel  with  a  woman-centered  design  that  has  the  potential  to  be  a  long-acting,  yet

convenient and user-controlled contraceptive option;

• DARE-LBT, a novel hydrogel formulation for delivery of live biotherapeutics to support vaginal health;

• DARE-GML, an intravaginally-delivered potential multi-target antimicrobial agent formulated with glycerol monolaurate (GML), which has shown broad

antimicrobial activity, killing bacteria and viruses;

• DARE-RH1, a novel approach to non-hormonal contraception for both men and women by targeting the CatSper ion channel; and

• DARE-PTB2, a novel approach for the prevention and treatment of idiopathic preterm birth through inhibition of a stress response protein.

DARE-LARC1, our potential user-controlled, long-acting reversible contraceptive, is designed to store and precisely deliver hundreds of therapeutic doses of
the contraceptive levonorgestrel over a period of years and to be controlled by the user, without further intervention by a healthcare provider. DARE-LARC1’s woman-
centered  design  seeks  to  offer  the  benefits  of  traditional  long-acting  reversible  contraceptives  with  the  added  flexibility  and  convenience  for  the  user  to  pause  and
resume release of levonorgestrel, depending on her desire for fertility or contraceptive protection. Under a grant agreement we entered into in June 2021, as amended,
we  may  receive  up  to  approximately  $49.0  million,  payable  over  approximately  five  years,  to  advance  development  of  the  technology  through  nonclinical  proof  of
principle studies to enable an IND submission. As of the date of this report, we have received payments totaling approximately $28.4 million under the grant agreement.
Additional payments are contingent upon the DARE-LARC1 program's achievement of development and reporting milestones specified in the grant agreement.

16

The  DARE-LBT  program  has  been  supported  by  a  private  foundation  grant  of  approximately  $585,000  under  a  grant  agreement  that  we  entered  into  in
November 2022. The grant funds supported activities related to development of a vaginal thermosetting gel formulation for the delivery of live biotherapeutics that can
be  reconstituted  at  the  point  of  care.  We  believe  DARE-LBT  merits  further  development  as  a  delivery  vehicle  with  potential  to  enhance  the  availability  of  novel
therapeutics  for  vaginal  health  in  the  United  States  and  worldwide,  including  in  countries  with  varying  climatic  conditions  and/or  where  extended  storage  may  be
required.

Sales and Marketing

We do not have established marketing, sales or distribution infrastructure or capabilities. In order to commercialize any of our product candidates if approved for
commercial sale, we must either establish a sales and marketing organization with technical expertise and supporting distribution capabilities or collaborate with third-
parties that have sales and marketing experience. Our approach is to develop an appropriate commercialization strategy for each of our product candidates based on
the  size  of  the  market  opportunity,  the  level  of  competition  and  the  anticipated  complexity  of  the  launch.  As  we  move  our  product  candidates  through  development
toward, and in some cases, through regulatory approval, we evaluate several options for each product candidate's commercialization strategy. These options include
building  our  own  sales  force  and  other  commercial  infrastructure,  entering  into  strategic  marketing  partnerships  with  third  parties,  including  commercial  sales
organizations or other pharmaceutical or biotechnology companies, out-licensing the product to other pharmaceutical or biotechnology companies, and combinations of
these strategies. Organon has global commercial rights to XACIATO under our exclusive license agreement, and we have an exclusive license agreement with Bayer to
out-license  U.S.  commercialization  of  Ovaprene.  Each  of  these  collaborators  has  established  marketing,  sales  and  distribution  capabilities  in  women's  health.  We
expect to continue to evaluate each product opportunity and pursue the commercialization strategy that we believe will maximize the return on our assets in and outside
of the U.S. for our stockholders. We have engaged third parties to assist in commercial planning and other commercial readiness activities for our product candidates
and intend to continue to do so, as needed.

See “Strategic Agreements for Product Commercialization” below for a discussion of the terms of our out-license agreements.

Manufacturing and Supply

We do not own or operate, nor do we expect to own or operate, facilities for manufacturing, storage and distribution, or testing of our product candidates. We
rely on third parties to supply and manufacture our product candidates and other materials necessary to conduct pre-clinical testing, clinical trials and other activities
required for regulatory approval of our product candidates, and expect to continue to do so in the future. In addition, to the extent our commercialization strategy for any
future approved product requires that we undertake commercial supply obligations, we intend to rely on contract manufacturers and suppliers for manufacture, storage,
distribution  and  testing  of  our  finished  commercial  products  and  their  respective  components,  including  the  active  pharmaceutical  ingredients,  or  API.  These
arrangements require less upfront capital expenditure and allow us to maintain a smaller and more flexible infrastructure.

Under  the  terms  of  our  license  agreement  with  Organon,  we  were  responsible  for  providing  product  supply  of  XACIATO  on  an  interim  basis  until  Organon
assumed such responsibility. In March 2022, we entered into a long-term supply and manufacturing agreement with the contract manufacturing organization, or CMO,
that  provided  clinical  supplies  of  XACIATO  for  our  pivotal  Phase  3  DARE-BVFREE  clinical  study.  Under  the  terms  of  our  agreement,  the  CMO  was  responsible  for
obtaining  supplies,  at  our  expense,  of  all  components  necessary  for  the  manufacture  of  XACIATO,  including  the  API,  clindamycin.  In  December  2023,  Organon
assumed our obligations under the agreement with the CMO and our product supply agreement with Organon was terminated.

Under our agreement with ADVA-Tec, ADVA-Tec is responsible for providing all clinical trial and commercial supplies of Ovaprene, either directly or through a
CMO, and except under limited circumstances, we may not obtain supplies of Ovaprene from any source other than ADVA-Tec or its CMO and licensor, Poly-Med, Inc.
Other  than  our  agreement  with  ADVA-Tec,  we  have  no  long-term  arrangements  for  the  production  or  supply  of  our  product  candidates  or  the  materials  required  to
produce them.

Under the terms of our license agreement with SST, SST was responsible for providing clinical supplies of Sildenafil Cream for Phase 2 clinical studies in the
U.S., and we are responsible for providing supplies of Sildenafil Cream for Phase 3 clinical development and, if approved, for marketing and sale. Currently, we plan to
obtain clinical supplies of Sildenafil Cream from the same CMO that manufactured Sildenafil Cream for the Phase 2b RESPOND clinical study.

17

We expect that our current arrangements will meet our foreseeable needs for clinical trial materials or, generally, that alternative supply sources will be readily
available.  However,  we  may  experience  manufacturing  and  supply  delays  and  disruptions  in  the  event  we  need  to  engage  alternative  supply  sources,  as  well  as  in
connection with our current CMOs scaling up production to meet our clinical supply requirements for later stage clinical studies. In addition, some key raw materials or
components of our clinical-stage product candidates, including Ovaprene and Sildenafil Cream, have only a single source of supply and alternative supply sources may
not be readily available. Global supply chain disruptions, including those related to recent and ongoing geopolitical events, may contribute to manufacturing and supply
delays.  See  ITEM  1A.  "RISK  FACTORS  –  Risks  Related  to  Product  Research  &  Development  and  Regulatory  Approval  –  Delays  in  the  manufacture  of  our  clinical
supplies  as  well  as  other  supply  chain  disruptions  could  postpone  the  initiation  of  or  interrupt  clinical  studies,  extend  the  timeframe  and  cost  of  development  of  our
product candidates, delay potential regulatory approvals and impact the commercialization of any approved products” below.

Strategic Agreements for Product Commercialization

Organon License Agreement
In March 2022, we entered into an agreement with Organon, which became fully effective in June 2022, whereby Organon licensed exclusive worldwide rights
to  develop,  manufacture  and  commercialize  XACIATO  and  other  future  intravaginal  or  urological  products  for  human  use  formulated  with  clindamycin  that  rely  on
intellectual property we control. In July 2022, we received a $10.0 million non-refundable and non-creditable payment from Organon, which was recorded as license fee
revenue.  In  July  2023,  received  a  $1.0  million  payment  from  Organon  in  connection  with  the  amendment  to  the  license  agreement  we  entered  into  which  was  also
recorded as license fee revenue. In connection with the first commercial sale of a licensed product in the United States, we received the $1.8 million milestone payment
from Organon in the fourth quarter of 2023.

Under the terms of the license agreement, as amended, we are entitled to receive tiered double-digit royalties based on net sales and potential future milestone
payments  of  up  to  $180.0  million  in  tiered  commercial  sales  milestones  and  regulatory  milestones.  Royalty  payments  will  be  subject  to  customary  reductions  and
offsets. The royalty period for each licensed product will continue on a country-by-country basis from the first commercial sale of the licensed product in the country until
the  expiration  of  the  later  of  (i)  the  date  that  no  valid  patent  claim  would  be  infringed  in  the  absence  of  the  license  granted  under  the  agreement  by  the  sale  of  the
licensed product in the country, (ii) 10 years after the end of the month in which the first commercial sale of the licensed product in the country occurred, and (iii) the
expiration of regulatory market exclusivity for the licensed product in that country.

Unless terminated earlier, the agreement will expire on a product-by-product and country-by-country basis upon expiration of the applicable royalty period for
each licensed product. In addition to customary termination rights for both parties, Organon may terminate the agreement in its entirety or on a country-by-country basis
at any time in Organon’s sole discretion on 120 days’ advance written notice.

The  agreement  includes  customary  representations  and  warranties,  covenants  and  indemnification  obligations  of  each  party.  In  addition,  the  terms  of  the

agreement provide Organon exclusive worldwide rights of first negotiation for specified potential future products of ours.

Bayer License Agreement

In  January  2020,  we  entered  into  a  license  agreement  with  Bayer  regarding  the  further  development  and  commercialization  of  Ovaprene  in  the  U.S.  We
received a $1.0 million upfront non-refundable payment from Bayer and Bayer agreed to support us in development and regulatory activities by providing the equivalent
of  two  experts  to  advise  us  in  clinical,  regulatory,  preclinical,  commercial,  CMC  and  product  supply  matters.  Bayer,  in  its  sole  discretion,  has  the  right  to  make  the
license effective by paying us an additional $20.0 million, referred to as the Clinical Trial and Manufacturing Activities Fee. Such license would be exclusive with regard
to the commercialization of Ovaprene for human contraception in the U.S. and co-exclusive with us with regard to development.

Milestone  Payments  Paid  by  Bayer.  We  will  be  entitled  to  receive  (a)  a  milestone  payment  in  the  low  double-digit  millions  upon  the  first  commercial  sale  of
Ovaprene  in  the  U.S.  and  escalating  milestone  payments  based  on  annual  net  sales  of  Ovaprene  during  a  calendar  year,  totaling  up  to  $310.0  million  if  all  such
milestones,  including  the  first  commercial  sale,  are  achieved,  (b)  tiered  royalties  starting  in  the  low  double  digits  based  on  annual  net  sales  of  Ovaprene  during  a
calendar year, subject to customary royalty reductions and offsets, and (c) a percentage of sublicense revenue.

18

Efforts. We will be responsible for the pivotal trial for Ovaprene and for its development and regulatory activities and we have product supply obligations. After

payment of the Clinical Trial and Manufacturing Activities Fee, Bayer will be responsible for the commercialization of Ovaprene for human contraception in the U.S.

Term. The initial term of the agreement, which is subject to automatic renewal terms, continues until the later of (a) the expiration of any valid claim covering the
manufacture, use, sale or import of Ovaprene in the U.S.; or (b) 15 years from the first commercial sale of Ovaprene in the U.S. In addition to customary termination
rights  for  both  parties,  Bayer  may  terminate  the  agreement  at  any  time  on  90  days’  notice  and  the  agreement  will  automatically  terminate  if  we  do  not  receive  the
Clinical Trial and Manufacturing Activities Fee if and when due.

Strategic Agreements for Pipeline Development

The  following  is  a  summary  of  certain  rights  and  obligations  under  our  strategic  agreements  and  describes  expenses  incurred  during  2023  and  our  future

payment or potential future payment obligations thereunder.

Douglas License Agreement / The University of Manchester Stand-by Direct License Arrangement

In  August  2023,  we  entered  into  a  license  agreement  with  Douglas  Pharmaceuticals  Limited,  or  Douglas,  under  which  we  acquired  the  exclusive  rights  to
develop and commercialize a lopinavir and ritonavir combination soft gel vaginal insert for the treatment of CIN and other HPV-related pathologies, and an agreement
with  The  University  of  Manchester,  pursuant  to  which  The  University  of  Manchester  consented  to  Douglas'  sublicense  to  us  of  certain  rights  it  previously  granted  to
Douglas and agreed to grant us a direct license to such rights if its license agreement with Douglas is terminated. As a result of these agreements, we commenced our
DARE-CIN  program.  Under  our  agreement  with  Douglas,  we  received  an  exclusive,  royalty-bearing  license  to  research,  develop  and  commercialize  the  licensed
intellectual property in the United States for the treatment or prevention of all indications for women in female reproductive health. We are entitled to sublicense the
rights granted to us under the agreement.

Milestone Payments.  We  agreed  to  make  potential  future  milestone  payments  to  Douglas  of  (1)  up  to  $5.25  million  in  the  aggregate  upon  achieving  certain
development and regulatory milestones, which may be paid in shares of our common stock, in our sole discretion subject to specified limitations, and (2) up to $64.0
million in the aggregate upon achieving certain commercial sales milestones for each product covered by the licenses granted under the agreement.

Royalty Payments. Douglas is eligible to receive tiered royalties in low single-digit to low double-digit percentages based on annual net sales of products and

processes covered by the licenses granted under the agreement.

Efforts. We must use commercially reasonable efforts to develop and introduce to market at least one product or process.

Term. Unless earlier terminated, the agreement expires upon the expiration of the last-to-expire royalty term. In addition to customary termination rights for both
parties,  we  may  elect  to  terminate  the  agreement  at  any  time,  with  or  without  cause,  upon  advance  written  notice  to  Douglas,  and  Douglas  may  terminate  the
agreement if we materially fail to fulfill diligence requirements with respect to product development.

Hennepin License Agreement

In August 2022, we entered into a license agreement with Hennepin Life Sciences LLC, or Hennepin, under which we acquired the exclusive global rights to
develop and commercialize treatments delivering the novel antimicrobial glycerol monolaurate (GML) intravaginally for a variety of health conditions including bacterial,
fungal, and viral infections. As a result of this license agreement, we commenced our DARE-GML program. Under the agreement, we received an exclusive, worldwide,
royalty-bearing license to research, develop and commercialize the licensed technology. We are entitled to sublicense the rights granted to us under the agreement.

Milestone Payments. We agreed to make potential future development and sales milestone payments of (1) up to $6.25 million in the aggregate upon achieving
certain  development  and  regulatory  milestones,  and  (2)  up  to  $45.0  million  in  the  aggregate  upon  achieving  certain  commercial  sales  milestones  for  each  product
covered by the licenses granted under the agreement, which may be paid, in our sole discretion, in cash or shares of our common stock.

19

Royalty Payments. Hennepin is eligible to receive tiered royalties in low single-digit to low double-digit percentages based on worldwide net sales of products

and processes covered by the licenses granted under the agreement.

Efforts. We must use commercially reasonable efforts to develop and introduce to market at least one product.

Term. Unless earlier terminated, the agreement expires in its entirety upon the last to expire royalty term. In addition to customary termination rights for both
parties, we may elect to terminate the agreement at any time, with or without cause, on a country-by-country basis, and Hennepin may terminate the agreement if we do
not undertake any development work with respect to the licensed intellectual property for five consecutive years from the date of the agreement.

Cooperative Research and Development Agreement with NICHD

In July 2021, we entered into a CRADA with the U.S. Department of Health and Human Services ("HHS"), as represented by NICHD, part of the NIH, for the
conduct of a pivotal Phase 3 clinical study of Ovaprene. See also “Our Pipeline: Clinical Stage Programs – Ovaprene” above. Pursuant to the terms of the CRADA, we
are responsible for providing clinical supplies of Ovaprene, coordinating interactions with the FDA, preparing and submitting supportive regulatory documentation, and
providing a total of $5.5 million to NICHD to be applied toward the costs of conducting the Phase 3 study, $5.0 million of which has been paid and we expect to make
the  remaining  $0.5  million  payment  in  the  third  quarter  of  2024.  NICHD  will  be  responsible  for  the  other  costs  related  to  the  conduct  of  the  Phase  3  study  and  will
manage the payment of expenses to other parties involved with the study. Either we or NICHD may terminate the CRADA for any reason upon 30 days’ prior written
notice to the other party. If the CRADA is terminated before completion of the Phase 3 study, NICHD will cooperate with us to transfer the data and the conduct of the
study to us or our designee and will continue to conduct the study for so long as necessary to enable such transfer to be completed without interrupting the study. If we
terminate the CRADA before the completion of any active study protocol, we generally will be responsible for providing sufficient clinical supplies of Ovaprene to NICHD
in  order  to  complete  the  study.  NICHD  may  retain  and  use  payments  we  make  under  the  CRADA  for  up  to  one  year  after  expiration  or  termination  to  cover  costs
associated with the conduct of activities described under the research plan in the CRADA that were initiated prior to expiration or termination, and any unused funds will
be returned to us. Under the CRADA, each party granted the other party rights to use their respective background inventions solely to the extent necessary to conduct
the activities described in the research plan in the CRADA. Subject to the U.S. government’s nonexclusive, nontransferable, irrevocable, paid-up right to practice any
CRADA invention for research or other government purposes, each party will own inventions, data and materials produced by its employees, and both parties will jointly
own inventions jointly invented by their employees in performing the research plan. Under the CRADA, we were granted an exclusive option to negotiate an exclusive or
nonexclusive development and commercialization license with a field of use that does not exceed the scope of the research plan to rights that the U.S. government may
have in inventions jointly or independently invented by NICHD employees for which a patent application is filed. The CRADA also contains customary representations,
warranties, and indemnification and confidentiality obligations. The CRADA expires five years from its effective date.

MBI Acquisition

In November 2019, we acquired Dare MB Inc. (formerly, Microchips Biotech, Inc.), or MBI, to secure the rights to develop a long-acting reversible contraception

method that a woman can turn on or off herself, according to her own needs. This candidate is now known as DARE-LARC1.

In  connection  with  the  MBI  acquisition,  we  issued  an  aggregate  of  approximately  3.0  million  shares  of  our  common  stock  to  the  holders  of  shares  of  MBI’s
capital stock outstanding immediately prior to the effective time of the merger and agreed to pay the former MBI stockholders: (a) up to $46.5 million contingent upon
the achievement of specified funding, product development and regulatory milestones; (b) up to $55.0 million contingent upon the achievement of specified amounts of
aggregate net sales of products incorporating the intellectual property we acquired in the merger; (c) tiered royalty payments ranging from low single-digit to low double-
digit percentages of annual net sales of such products sold by us (but not by sublicensees), subject to customary provisions permitting royalty reductions and offset; and
(d) a percentage of sublicense revenue related to such products. We agreed to use commercially reasonable efforts to achieve specified development and regulatory
objectives  relating  to  DARE-LARC1.  In  June  2021,  a  total  of  $1.25  million  of  the  contingent  consideration  became  payable  upon  the  achievement  of  certain  of  the
funding  and  product  development  milestone  events,  $1.0  million  of  which  was  recorded  as  contingent  consideration  on  our  consolidated  balance  sheets  upon  the
completion of the MBI acquisition and $250,000 of which

20

was expensed in 2021. In July 2021, our board of directors elected to make these milestone payments in shares of our common stock, to the extent permissible under
the terms of the merger agreement with MBI, and, in September 2021, we issued approximately 700,000 shares of our common stock to former stockholders of MBI
and  paid  $75,000  in  cash  to  the  stockholders'  representative  in  accordance  with  the  terms  of  the  merger  agreement  in  satisfaction  of  the  $1.25  million  in  milestone
payments associated with milestones achieved in June 2021.

TriLogic and MilanaPharm License Agreement / Hammock Assignment Agreement

In  December  2018,  we  entered  into  (a)  an  Assignment  Agreement  with  Hammock  Pharmaceuticals,  Inc.,  or  the  Assignment  Agreement,  and  (b)  a  First
Amendment to License Agreement with TriLogic Pharma, LLC and MilanaPharm LLC, or the License Amendment. Both agreements relate to the Exclusive License
Agreement among Hammock, TriLogic and MilanaPharm dated as of January 9, 2017, or the MilanaPharm License Agreement. Under the Assignment Agreement and
the  MilanaPharm  License  Agreement,  as  amended  by  the  License  Amendment,  we  acquired  an  exclusive,  worldwide  license  under  certain  intellectual  property  to,
among other things, develop and commercialize products for the diagnosis, treatment and prevention of human diseases or conditions in or through any intravaginal or
urological applications. The licensed intellectual property relates to the hydrogel drug delivery platform of TriLogic and MilanaPharm known as TRI-726. In XACIATO,
this  proprietary  technology  is  formulated  with  clindamycin  for  the  treatment  of  bacterial  vaginosis.  In  December  2019,  we  entered  into  amendments  to  each  of  the
Assignment Agreement and License Amendment. In September 2021, we entered into a second amendment to the License Agreement. In March 2022, in connection
with entering into our exclusive license agreement with Organon, we entered into a consent, waiver and stand-by license agreement with TriLogic, MilanaPharm and
Organon, which further amended the License Agreement.

License Amendment, as amended:

Milestone Payments.  We  paid  MilanaPharm  $500,000  in  connection  with  the  first  commercial  sale  in  the  United  States  of  XACIATO  in  the  fourth  quarter  of
2023. We may pay up to $250,000 upon the first commercial sale in the United States of successive licensed products for each vaginal or urological use. In addition,
upon achievement of $50.0 million in cumulative worldwide net sales of licensed products, we must pay $1.0 million to MilanaPharm.

Foreign Sublicense Income. MilanaPharm is eligible to receive a low double-digit percentage of all income received by us or our affiliates in connection with any

sublicense granted to a third party for use outside of the United States, subject to certain exclusions.

Royalty Payments. During the royalty term, MilanaPharm is eligible to receive high single-digit to low double-digit royalties based on annual worldwide net sales
of licensed products and processes. The royalty term, which is determined on a country-by-country basis and licensed product-by-product basis (or process-by-process
basis), begins with the first commercial sale of a licensed product or process in a country and terminates on the latest of (1) the expiration date of the last valid claim of
the licensed patent rights that cover the method of use of such product or process in such country, or (2) 10 years following the first commercial sale of such product or
process in such country. Royalty payments are subject to reduction in certain circumstances, including as a result of generic competition, patent prosecution expenses
incurred by us, or payments to third parties for rights or know-how required for us to exercise the licenses granted to it under the MilanaPharm License Agreement or
that are strategically important or could add value to a licensed product or process in a manner expected to materially generate or increase sales.

Efforts. We must use commercially reasonable efforts and resources to (1) develop and commercialize at least one licensed product or process in the United
States and at least one licensed product or process in at least one of Canada, the United Kingdom, France, Germany, Italy or Spain, and (2) continue to commercialize
that product or process following the first commercial sale of a licensed product or process in the applicable jurisdiction.

Term. Unless  earlier  terminated,  the  license  term  continues  until  (1)  on  a  licensed  product-by-product  (or  process-by-process  basis)  and  country-by-country
basis, the date of expiration of the royalty term with respect to such licensed product in such country, and (2) the expiration of all applicable royalty terms under the
MilanaPharm License Agreement with respect to all licensed products and processes in all countries. Upon expiration of the term with respect to any licensed product or
process in a country (but not upon earlier termination of the MilanaPharm License Agreement), the licenses granted to us under the MilanaPharm License Agreement
will convert automatically to an exclusive, fully paid-up, royalty-free, perpetual, non-terminable and irrevocable right and license under the licensed intellectual property.

In  addition  to  customary  termination  rights  for  all  parties,  MilanaPharm  may  terminate  the  license  granted  to  us  solely  with  respect  to  a  licensed  product  or

process in a country if, after having launched such product or process

21

in such country, (1) we or our affiliates or sublicensees discontinue the sale of such product or process in such country and MilanaPharm notifies us of such termination
within  60  days  of  having  first  been  notified  by  us  of  such  discontinuation,  or  (2)  we  or  our  affiliates  or  sublicensees  (A)  discontinue  all  commercially  reasonable
marketing efforts to sell, and discontinue all sales of, such product or process in such country for nine months or more, (B) fail to resume such commercially reasonable
marketing  efforts  within  120  days  of  having  been  notified  of  such  failure  by  MilanaPharm,  (C)  fail  to  reasonably  demonstrate  a  strategic  justification  for  the
discontinuation and failure to resume to MilanaPharm, and (D) MilanaPharm gives 90 days’ notice to us.

Assignment Agreement, as amended

Assignment; Technology Transfer. Hammock assigned and transferred to us all of its right, title and interest in and to the MilanaPharm License Agreement and
agreed to cooperate to transfer to us all of the data, materials and the licensed technology in its possession pursuant to a technology transfer plan to be agreed upon by
the parties, with a goal for us to independently practice the licensed intellectual property as soon as commercially practical in order to develop and commercialize the
licensed products and processes.

Milestone Payments. Hammock is eligible to receive up to $250,000 in the aggregate upon achievement of a regulatory development milestone related to a

non-bacterial vaginosis product.

Term. The Assignment Agreement will terminate upon the later of (1) completion of the parties’ technology transfer plan, and (2) payment to Hammock of the

last of the milestone payments.

Pear Tree Acquisition and License Agreements

In  May  2018,  we  completed  our  acquisition  of  Pear  Tree  Pharmaceuticals,  Inc.,  or  Pear  Tree.  We  acquired  Pear  Tree  to  secure  exclusive,  sublicensable,
worldwide rights under certain patents and know-how to develop and commercialize a proprietary formulation of tamoxifen for vaginal administration. This acquisition
led to our DARE-VVA1 program. Under the merger agreement, former stockholders of Pear Tree are eligible to receive tiered royalties based on net sales of licensed
products by us or our affiliates, subject to customary reductions and offsets and to offset by royalty and sublicense revenue share payments payable to Pear Tree’s
licensors as further described below, and a percentage of sublicense revenue. Former stockholders of Pear Tree and Pear Tree’s licensors are also eligible to receive
payments based on achievement of specified clinical development, regulatory and commercial milestones by licensed products as further described below.

Milestone Payments. Former stockholders of Pear Tree are eligible to receive up to $15.5 million in the aggregate in payments based on the achievement of
clinical development and regulatory milestones by licensed products and up to $47.0 million in the aggregate in payments based on the achievement of commercial
milestones by licensed products. These payments shall only be due once upon the first occurrence any of the specified milestone events. In addition, licensors of Pear
Tree are eligible to receive up to approximately $3.2 million in the aggregate in payments based on the achievement of clinical development, regulatory and commercial
milestones by each licensed product. These milestone payments may be made, in our sole discretion, in cash or in shares of our common stock in accordance with the
terms of the merger agreement and the license agreements.

Royalty Payments; Sublicense Revenue Share. Former stockholders of Pear Tree are eligible to receive tiered royalties based on single-digit to low double-digit
percentages  of  annual  net  sales  of  licensed  products  by  us  or  our  affiliates,  subject  to  customary  reductions  and  offsets,  and  a  portion  of  royalties  we  receive  from
sublicensees. These payments may be made, in our sole discretion, in cash or in shares of our common stock in accordance with the terms of the merger agreement.
Pear Tree’s licensors are eligible to receive semi-annual royalties based on a single-digit percentage of net sales of licensed products by us or our affiliates, subject to
customary reductions and offsets, or a portion of any royalties received by us or our affiliates from sublicensees, and a low double-digit percentage of all sublicensing
fees or other lump sum payments or compensation we receive from sublicensees, subject to customary exclusions. Portions of certain milestone payments made to
Pear Tree’s licensors may be creditable against royalty payments due to Pear Tree’s licensors.

License  Agreements  Revenue  Share  Offset.  Under  the  merger  agreement,  in  addition  to  customary  royalty  reductions  and  offsets,  royalty  payments  and
payments  based  on  income  received  from  sublicensees  of  licensed  products  made  by  us  to  Pear  Tree’s  licensors  are  creditable  against  all  royalty  and  sublicense
revenue share payments payable to former stockholders of Pear Tree.

22

Catalent JNP License Agreement

In April 2018, we entered into an exclusive license agreement with Catalent JNP, Inc. (formerly known as Juniper Pharmaceuticals, Inc., and which we refer to
as  Catalent  in  this  report),  under  which  Catalent  granted  us  (a)  an  exclusive,  royalty-bearing  worldwide  license  under  certain  patent  rights,  either  owned  by  or
exclusively  licensed  to  Catalent,  to  make,  have  made,  use,  have  used,  sell,  have  sold,  import  and  have  imported  products  and  processes;  and  (b)  a  non-exclusive,
royalty-bearing worldwide license to use certain technological information owned by Catalent to make, have made, use, have used, sell, have sold, import and have
imported products and processes. As a result of this license agreement, we commenced our DARE-HRT1, DARE-FRT1 and DARE-PTB1 programs. We are entitled to
sublicense the rights granted to us under this agreement.

Annual Maintenance Fee. We pay an annual license maintenance fee of $100,000 to Catalent on each anniversary of the date of the agreement, which will be
creditable  against  royalties  and  other  payments  due  to  Catalent  in  the  same  calendar  year  (including  milestone  payments  and  sublicense  income),  but  may  not  be
carried forward to any other year.

Milestone Payments.  Catalent  is  eligible  to  receive  (1)  up  to  $12.5  million  in  the  aggregate  in  payments  based  on  the  achievement  of  specified  clinical  and
regulatory milestones, and (2) up to $30.3 million in the aggregate in payments based on the achievement of specified commercial sales milestones for each product or
process covered by the licenses granted under the agreement.

Royalty Payments. During the royalty term, Catalent is eligible to receive mid single-digit to low double-digit royalties based on worldwide net sales of products
and  processes  covered  by  the  licenses  granted  under  the  agreement.  In  lieu  of  such  royalty  payments,  we  will  pay  Catalent  a  low  double-digit  percentage  of  all
sublicense income we receive for the sublicense of rights under the agreement to a third party. The royalty term, which is determined on a country-by-country basis and
product-by-product basis (or process-by-process basis), begins with the first commercial sale of a product or process in a country and terminates on the latest of (1) the
expiration date of the last valid claim within the licensed patent rights with respect to such product or process in such country, (2) 10 years following the first commercial
sale of such product or process in such country, and (3) when one or more generic products for such product or process are commercially available in such country,
except that if there is no such generic product by the 10th year following the first commercial sale in such country, then the royalty term will terminate on the 10-year
anniversary of the first commercial sale in such country.

Efforts.  We  must  use  commercially  reasonable  efforts  to  develop  and  make  at  least  one  product  or  process  available  to  the  public,  which  efforts  include

achieving specific diligence requirements by specific dates specified in the agreement.

Term. Unless earlier terminated, the term of the agreement will continue on a country-by-country basis until the later of (1) the expiration date of the last valid
claim within such country, or (2) 10 years from the date of first commercial sale of a product or process in such country. Upon expiration (but not early termination) of the
agreement, the licenses granted thereunder will convert automatically to fully-paid irrevocable licenses. Catalent may terminate the agreement (1) upon 30 days’ notice
for our uncured breach of any payment obligation under the agreement, (2) if we fail to maintain required insurance, (3) immediately upon our insolvency or the making
of an assignment for the benefit of our creditors or if a bankruptcy petition is filed for or against us, which petition is not dismissed within 90 days, or (4) upon 60 days’
notice for any uncured material breach by us of any of our other obligations under the agreement. We may terminate the agreement on a country-by-country basis for
any reason by giving 180 days’ notice (or 90 days’ notice if such termination occurs prior to receipt of marketing approval in the United States). If Catalent terminates
the agreement for the reason described in clause (4) above or if we terminate the agreement, Catalent will have full access including the right to use and reference all
product data generated during the term of the agreement that is owned by us.

Adare Development and Option Agreement
In March 2018, we entered into an exclusive development and option agreement with Adare Pharmaceuticals USA, Inc. (formerly known as Orbis Biosciences,
Inc.,  and  which  we  refer  to  as  Adare),  for  the  development  and  potential  exclusive  worldwide  license  of  injectable  formulations  of  etonogestrel  for  contraceptive
protection over 6-month and 12-month periods (which we refer to as DARE-204 and DARE-214, respectively). The agreement, as amended, provides us with an option
to negotiate an exclusive, worldwide, royalty-bearing license, with rights to sublicense, for the programs if we fund the conduct of specified development work. We have
no obligation to exercise our option.

23

SST License and Collaboration Agreement

In February 2018, we entered into a license and collaboration agreement with Strategic Science & Technologies-D LLC and Strategic Science & Technologies,
LLC, referred to collectively as SST, under which we received an exclusive, royalty-bearing, sublicensable license to develop and commercialize, in all countries and
geographic territories of the world, for all indications for women related to female sexual dysfunction and/or female reproductive health, including treatment of female
sexual arousal disorder, or the Field of Use, SST's topical formulation of Sildenafil Cream as it existed as of the effective date of this agreement, or any other topically
applied  pharmaceutical  product  containing  sildenafil  or  a  salt  thereof  as  a  pharmaceutically  active  ingredient,  alone  or  with  other  active  ingredients,  but  specifically
excluding any product containing ibuprofen or any salt derivative of ibuprofen, or the Licensed Products.

Invention Ownership. We retain rights to inventions made by our employees, SST retains rights to inventions made by its employees, and each party owns a

50% undivided interest in all joint inventions.

Joint Development Committee. The parties will collaborate through a joint development committee that will determine the strategic objectives for, and generally

oversee, the development efforts of both parties under the agreement.

Development. We must use commercially reasonable efforts to develop the Licensed Products in the Field of Use in accordance with a development plan in the
agreement, and to commercialize the Licensed Products in the Field of Use. We are responsible for all reasonable internal and external costs and expenses incurred by
SST in its performance of the development activities it must perform under the agreement.

Royalty Payments. SST will be eligible to receive tiered royalties based on percentages of annual net sales of Licensed Products in the single digits to the mid

double digits, subject to customary royalty reductions and offsets, and a percentage of sublicense revenue.

Milestone Payments. SST will be eligible to receive payments (1) ranging from $0.5 million to $18.0 million in the aggregate upon achieving certain clinical and
regulatory milestones in the U.S. and worldwide, and (2) between $10.0 million to $100.0 million in the aggregate upon achieving certain commercial sales milestones.
If we enter into strategic development or distribution partnerships related to the Licensed Products, additional milestone payments would be due to SST.

License Term. Our license continues on a country-by-country basis until the later of 10 years from the date of the first commercial sale of such Licensed Product
or the expiration of the last valid claim of patent rights covering the Licensed Product in the Field of Use. Upon expiration (but not termination) of the agreement in a
particular country, we will have a fully paid-up license under the licensed intellectual property to develop and commercialize the applicable Licensed Products in the
applicable country on a non-exclusive basis.

Termination. In addition to customary termination rights for both parties: (1) prior to receipt of approval by a regulatory authority necessary for commercialization
of a Licensed Product in the corresponding jurisdiction, including NDA approval, we may terminate the agreement without cause upon 90 days prior written notice; (2)
following receipt of approval by a regulatory authority necessary for commercialization of a Licensed Product in the corresponding jurisdiction, including NDA approval,
we may terminate the agreement without cause upon 180 days prior written notice; and (3) SST may terminate the agreement with respect to the applicable Licensed
Product(s)  in  the  applicable  country(ies)  upon  30  days’  notice  if  we  fail  to  use  commercially  reasonable  efforts  to  perform  development  activities  in  substantial
accordance with the development plan and do not cure such failure within 60 days of receipt of SST's notice thereof.

ADVA-Tec License Agreement

In March 2017, we entered into a license agreement with ADVA-Tec, Inc., under which we were granted an exclusive license to develop and commercialize
Ovaprene  for  human  contraceptive  use  worldwide.  We  must  use  commercially  reasonable  efforts  to  develop  and  commercialize  Ovaprene,  and  must  meet  certain
minimum spending amounts per year, including $2.5 million per year to cover such activities until a final PMA is filed, or until the first commercial sale of Ovaprene,
whichever occurs first. ADVA-Tec will conduct certain research and development work as necessary to allow us to seek a PMA from the FDA. ADVA-Tec is responsible
for providing us with clinical trial and commercial supplies of Ovaprene, either directly or through a CMO, on commercially reasonable terms, and, except under limited
circumstances, we may not obtain supplies of Ovaprene from another source.

24

Under  the  license  agreement,  in  addition  to  an  exclusive,  sublicensable  license  to  ADVA-Tec’s  and  its  affiliates’  intellectual  property  rights  for  all  uses  of

Ovaprene as a human contraceptive device, we have a right of first refusal to license these patents and patent applications for additional indications.

Milestone Payments. We may pay to ADVA-Tec: (1) up to $13.0 million in the aggregate based on the achievement of specified development and regulatory
milestones  and  (2)  up  to  $20  million  in  the  aggregate  based  on  the  achievement  of  certain  worldwide  net  sales  milestones.  The  future  development  and  regulatory
milestones  include:  successful  completion  of  a  Phase  3/pivotal  clinical  trial;  the  FDA’s  acceptance  of  a  PMA  filing  for  Ovaprene;  the  FDA’s  approval  of  the  PMA  for
Ovaprene; CE Marking of Ovaprene in at least three designated European countries; obtaining regulatory approval in at least three designated European countries; and
obtaining regulatory approval in Japan.

Royalty Payments. ADVA-Tec is eligible to receive royalties based on aggregate annual net sales of Ovaprene in specified regions at a royalty rate that will vary

between 1% and 10% and will increase based on various net sales thresholds, subject to customary reductions and offsets.

Sublicense  Revenue  Payments.  If  we  sublicense  our  rights  under  the  license  agreement,  in  lieu  of  royalty  payments  to  ADVA-Tec,  ADVA-Tec  is  eligible  to
receive a double-digit percentage of sublicense revenue received by us during the royalty term; provided, however, that for sublicense revenue we receive prior to the
first commercial sale of a licensed product that represents an upfront payment or license fee due on or around the effective date of the sublicense, ADVA-Tec is eligible
to receive a single-digit percentage of that sublicense revenue.

Term. Unless earlier terminated, the license we received under the agreement continues on a country-by-country basis until the later of the life of the licensed
patents or our last commercial sale of Ovaprene. In addition to customary termination rights for both parties: (A) we may terminate the agreement with or without cause
in whole or on a country-by-country basis upon 60 days prior written notice; and (B) ADVA-Tec may terminate the agreement if we develop or commercialize any non-
hormonal  ring-based  vaginal  contraceptive  device  competitive  to  Ovaprene  or  if  we  fail  to:  (1)  in  certain  limited  circumstances,  commercialize  Ovaprene  in  certain
designated  countries  within  three  years  of  the  first  commercial  sale  of  Ovaprene;  (2)  satisfy  the  annual  spending  obligation  described  above,  (3)  use  commercially
reasonable  efforts  to  complete  all  necessary  pre-clinical  and  clinical  studies  required  to  support  and  submit  a  PMA,  or  (4)  conduct  clinical  trials  as  set  forth  in  the
development plan to which we and ADVA-Tec agree, and as may be modified by a joint research committee, unless such failure is caused by events outside of our
reasonable control.

Royalty Interest Financing Agreement

In December 2023, we entered into a royalty interest financing agreement with United in Endeavour, LLC, or United, pursuant to which we sold to United an
interest in the royalty and milestone payments we receive from Organon in respect of net sales of XACIATO. On the effective date of the agreement, we received a
payment of $5.0 million, or the Initial Investment, from United. Until December 31, 2026, we may, at our sole discretion, elect to receive three additional payments of up
to  an  aggregate  of  $7.0  million.  We  refer  to  each  such  payment  as  a  Supplemental  Discretionary  Investment  Amount,  and  collectively,  as  the  Total  Supplemental
Discretionary Investment Amount.

We will make payments to United under the agreement until such time when United has received aggregate payments equaling a 12% internal rate of return, or
the IRR, on the Initial Investment and the Total Supplemental Discretionary Investment Amount, if any (referred to as the Hard Cap). Until such time as the IRR has
been achieved, we agreed to make payments to United equal to (i) from the date of the agreement through December 31, 2025, 50% of the amount of royalty payments
remaining after all amounts that are due and payable and actually paid by us to any licensor or sublicensee on the royalty payments generated and received by us on
net sales of XACIATO by Organon have been deducted (such payments referred to as the Net Royalty Payments), (ii) from January 1, 2026 through December 31,
2029, 75% of the Net Royalty Payments, and (iii) from the date of the agreement through December 31, 2029, 10% of the amount of milestone payments remaining
after all amounts that are due and payable and actually paid by us to any licensor or sublicensee on the milestone payments generated and received by us on net sales
of XACIATO by Organon have been deducted. After December 31, 2029, we will be required to make certain additional payments to United to the extent United has not
received payments equaling the Hard Cap by December 31, 2029, December 31, 2033, and December 31, 2034, respectively. In addition, if United has not received
payments equaling the Hard Cap by December 31, 2035 and we have other sources of assets or income besides XACIATO sufficient to complete such payments, we
have agreed to pay United quarterly payments evenly divided over a two-year term, such that United will have obtained the IRR, taking into account all other payments
received by United from us under the agreement. United’s right to receive payments will terminate when United has received the Hard Cap.

25

We have the right, but not the obligation, at any time, to repurchase all of the interest from United at a repurchase price equal to the Hard Cap, calculated as of the date
of we exercise such call option.

The agreement contains representations and warranties, covenants, indemnification obligations, and other provisions customary for transactions of this nature
and will terminate on the date that is the earlier of (i) the date upon which the payment of the purchased interest in respect of XACIATO is made in full to United, and (ii)
the payment to United of an aggregate amount equal to the Hard Cap.

In connection with the agreement, we issued to United a warrant to purchase up to 5.0 million shares of our common stock. In addition, for every $1.0 million of
Supplemental Discretionary Investment Amount, we agreed to issue an additional warrant to purchase up to 1.0 million shares of our common stock, for an aggregate of
additional warrants to purchase up to 7.0 million shares of our common stock.

The warrants are exercisable, in full or in part, at any time on or prior to the fifth anniversary of the date of issuance of the particular warrant at an exercise price
of  $0.3467  per  share,  subject  to  customary  anti-dilution  adjustments.  The  warrants  may  be  exercised  for  cash,  or  if  at  the  time  of  exercise  there  is  no  effective
registration statement registering for resale the shares underlying the warrants, then in lieu of paying the exercise price in cash, the holder may elect to exercise the
warrant on a cashless basis.

Intellectual Property

We actively seek to protect the proprietary technology that we consider important to our business in the United States and other jurisdictions internationally. We

also rely upon trade secrets and contracts to protect our proprietary information. 

Patents

The medical device and pharmaceutical industries are characterized by the existence of a large number of patents and frequent litigation based on allegations
of patent infringement. Patent litigation can involve complex factual and legal questions, and its outcome is uncertain. Any claim relating to infringement of third party
patents  that  is  successfully  asserted  against  us  or  our  licensors  may  require  us  to  pay  substantial  damages  or  may  limit  our  or  our  licensors'  ability  to  rely  on  such
patent protection. Any third party claim successfully alleging the invalidity or unenforceability of the patents may also limit our or our licensors' ability to rely on such
patent protection. Even if we, or our licensors were to prevail in any such action, any litigation could be costly and time-consuming and would divert the attention of
management and key personnel from our business operations. Also, if our product candidates or any future products are found to infringe the patents of others, our
development,  manufacture,  and  sale  of  these  potential  products  could  be  severely  restricted  or  prohibited.  In  addition,  there  can  be  no  assurance  that  any  patent
applications  filed  by  us  or  our  licensors  will  result  in  the  grant  of  a  patent  either  in  the  United  States  or  elsewhere,  or  that  any  patents  granted  will  be  valid  and
enforceable, or that any patents will provide a competitive advantage or afford protection against competitors with similar technologies. Because of the importance of
the patents underlying our product candidates, our business and our prospects may be harmed if we fail to maintain existing or obtain new patent rights or if we and our
licensors fail to protect key intellectual property rights.

Under  the  terms  of  the  Assignment  Agreement  with  Hammock  Pharmaceuticals,  Inc.  and  the  License  Amendment  with  TriLogic  Pharma,  LLC  and
MilanaPharm, LLC, regarding the thermosetting hydrogel platform which includes XACIATO, we are the exclusive licensee of three issued U.S. patents, two of which
are set to expire in December 2028 and one of which is set to expire in September 2036, subject to any extensions or disclaimers, and three foreign patents, including
one European Patent Office, or EPO, patent validated in four countries, that expire in December 2028, subject to any extensions or disclaimers, as well as two foreign
patents, including one EPO patent validated in 22 countries, that expire in July 2036, subject to any extensions or disclaimers. One of the three issued U.S. patents is
listed  in  the  FDA’s  compendium  of  “Approved  Drug  Products  with  Therapeutic  Equivalence  Evaluation,"  known  as  the  Orange  Book,  under  the  Patent  Exclusivity
Information for XACIATO. In addition, we have rights to three pending foreign patent applications and one pending U.S. patent application. If issued, the patent term for
any patents issuing from these pending applications would be expected to expire in 2036, subject to any extensions or disclaimers. We own a pending PCT application
and one foreign application regarding XACIATO, and a pending PCT application directed to the thermosetting hydrogel platform. The patent term for any patents issuing
from these pending applications would be expected to expire in 2042, subject to any extensions or disclaimers. Organon has licensed XACIATO-specific patents and
applications from us.

Under the terms of the ADVA-Tec license agreement, regarding Ovaprene, we are the exclusive licensee of nine granted U.S. patents, one pending U.S. patent

application, seven granted foreign patents, including four EPO

patents validated in a total of 55 countries, and four pending foreign patent applications. Two of the U.S. patents have terms until August 2028, which includes days
added to the term by patent term adjustment, and a third patent has a term that expires in July 2027, including patent term adjustment, each of such terms being subject
to any future extensions or disclaimers. The other U.S. and foreign patents are expected to expire in 2024, 2025, or 2026. The patent terms for any patents issuing from
the pending applications would be expected to expire in 2035, subject to any extensions or disclaimers.

Under the terms of the SST license agreement, regarding Sildenafil Cream, we are the exclusive licensee in the Field of Use of 23 issued patents worldwide (10
U.S. patents and 13 foreign patents, including two EPO patents validated in a total of 20 countries). Additionally, there is one patent application pending in the US, one
in Europe, and two in other international markets. The issued U.S. patents have a patent term that expires in June 2029, including any patent term adjustment, and may
be eligible for regulatory exclusivity under the Hatch-Waxman Act, while several foreign patents have a term that is set to expire in late 2031, each of such terms being
subject to any future extensions or disclaimers.

Under the terms of the Catalent license agreement, regarding our intravaginal ring platform which includes DARE-HRT1, we are the exclusive licensee of four
issued U.S. patents with patent terms set to expire in April 2024, November 2024, February 2025, and September 2027, including patent term adjustment, four issued
foreign patents with patent terms until April 2024, including one European patent validated in three countries, as well as one pending U.S. application and two pending
foreign  applications  that  if  granted  are  expected  to  have  patent  terms  that  expire  in  May  2038,  subject  to  any  extensions  or  disclaimers.  Additionally,  relative  to  the
DARE-HRT1 program, we are the sole owner of two pending U.S. provisional patent applications with an expected term, if granted, until 2044, subject to any extensions
or disclaimers.

When we acquired Pear Tree Pharmaceuticals, Inc. in 2018, regarding DARE-VVA1, we obtained the rights to three U.S. patents and one Japanese patent. The
patent terms for the U.S. patents are expected to expire in June 2027, June 2028, and May 2035 including any patent term adjustment, extensions or disclaimers. The
Japanese patent has a term that is set to expire in June 2027. Additionally, relative to the DARE-VVA1 program, we are the sole owner of one pending U.S. provisional
patent application with an expected term, if granted, until 2044, subject to any extensions or disclaimers.

When we acquired MBI in 2019, we obtained the rights to over 100 patents and applications. The key technology underlying the platform currently is supported
by 14 U.S. patents and 49 foreign patents, including six EPO patents validated in various European countries, and 12 pending patent applications. We believe that the
four most recently filed patent families are directly applicable to our DARE-LARC1 program. Those patent families have patent terms that are set to expire 2032, 2033,
2034,  and  2040  respectively,  subject  to  any  extensions  or  disclaimers.  Those  patent  families  include  patents  granted  in  the  U.S.,  E.U.  and  other  key  international
markets.

Under the terms of the Hennepin license agreement, we are the exclusive licensee of five issued U.S. patents and four foreign patents, as well as four pending
U.S. applications and twelve pending foreign applications. The U.S. patents are set to expire in 2025, 2026, 2028, 2033 and 2034 including any patent term adjustment,
extensions  or  disclaimers,  and  the  foreign  patents  have  patent  terms  until  2025  or  2033.  The  U.S.  and  foreign  applications,  if  granted,  are  expected  to  have  patent
terms that expire in 2033, 2037, 2038, and 2042, subject to any extensions or disclaimers.

Under the terms of the Douglas license agreement, we are the exclusive licensee of three granted U.S. patents and four pending U.S. patent applications. The

Competition

The industries in which we operate (biopharmaceutical, specialty pharmaceutical, biotechnology and medical device) are highly competitive and subject to rapid
and significant change. Our success is highly dependent upon our ability to acquire or in-license, develop and obtain regulatory approval for innovative medical products
on a cost-effective basis and to market them successfully, either on our own or together with strategic partners. We face and will continue to face intense competition
from a variety of businesses, including large, fully integrated, well-established pharmaceutical companies that already possess a significant share of the women’s health
market. Many of our potential competitors have greater clinical, regulatory, manufacturing, marketing, distribution, compliance and financial resources and experience
than we do. See ITEM 1A. "RISK FACTORS—Risks Related to Commercialization of XACIATO and Our Product Candidates— Our product candidates, if approved,
and XACIATO will face intense competition and our business and operating results will suffer if we, or our commercial collaborators, fail to compete effectively” and “—
The  women's  health  market  includes  many  generic  products  and  growth  in  generics  is  expected  to  continue,  which  could  make  the  successful  introduction  of  our
branded products difficult and expensive” below.

XACIATO will compete directly with the multiple generic and branded prescription drug products currently approved in the U.S. for the treatment of bacterial
vaginosis, including oral and vaginal gel formulations of metronidazole and vaginal cream formulations of clindamycin. Branded, single-dose FDA-approved products for
bacterial vaginosis include Solosec® (secnidazole) oral granules manufactured for and distributed by Lupin Pharmaceuticals, Inc., Clindesse® (clindamycin phosphate)
vaginal cream, 2% manufactured and distributed by Padagis, and Nuvessa™ (metronidazole vaginal gel 1.3%) distributed by Exeltis USA, Inc. Based on the XACIATO
product profile reflected in the FDA-approved prescribing information, including the consistent cure rates demonstrated among the subsets of patients defined by prior
episodes of bacterial vaginosis (≤ 3 and >3 episodes in the previous 12 months), and the labeling for special populations such as pregnant and lactating women, we
expect that the product may to be used by health care providers as a first line option for treating bacterial vaginosis. As a result of our exclusive license agreement with
Organon, the commercial success of XACIATO is largely outside of our control.

Our investigational contraceptive products, including Ovaprene, if approved, will compete with a wide range of prescription and over-the-counter contraceptive
options,  including  hormone-free  options  such  as  condoms,  diaphragms,  cervical  caps,  sponges,  copper  IUDs,  spermicides  and  vaginal  gels,  as  well  as  hormonal
products such as pills, patches, vaginal rings and injectables. In addition, multiple new methods of pregnancy prevention are in development, including hormone-free
options, and some may be marketed in the U.S. before Ovaprene, potentially adding to the level of market competition Ovaprene will face, if approved.

Currently, there are no FDA-approved therapies for FSAD. Sildenafil Cream has the potential to be the first FDA-approved product for the treatment of FSAD.

DARE-HRT1, if approved as a treatment for moderate to severe VMS due to menopause, will compete with the many products on the market targeted or FDA-
approved for the treatment of menopausal symptoms, including VMS. Such products include hormone therapies in the form of pills, patches and creams, some of which
are FDA-approved products and others which are prepared in compounding pharmacies. We expect the options for hormone therapy to continue to expand with time.
We believe DARE-HRT1 has the potential to address a preference among some women and health care providers for bio-identical hormones delivered in a non-oral
route, as well as offer convenience compared to existing FDA-approved hormone therapies in that one IVR is designed to deliver the bio-identical hormones over 28
days without any daily intervention.

Over the longer term, our ability, independently or otherwise, to successfully develop, manufacture, market, distribute and sell any approved products, expand
their usage or bring additional new products to the marketplace will depend on many factors, including, but not limited to, FDA and foreign regulatory agency approval of
new products and of new indications for existing products, the efficacy and safety of our products (alone and relative to other treatment options), the degree of patent or
other protection afforded to particular products, and reimbursement for use of those products.

Many  other  organizations  are  developing  drug  products  and  other  therapies  intended  to  treat  the  same  diseases  and  conditions  for  which  our  product
candidates  are  in  development,  and  the  success  of  others  may  render  potential  application  of  our  product  candidates  obsolete  or  noncompetitive,  even  prior  to
completion of its development.

Government Regulation

Governmental  authorities  in  the  U.S.,  at  the  federal,  state  and  local  level,  and  other  countries  extensively  regulate  the  research,  development,  testing,
manufacturing,  labeling  and  packaging,  storage,  recordkeeping,  advertising,  promotion,  import,  export,  marketing,  and  distribution,  among  other  things,  of
pharmaceutical,  medical  device,  and  drug-device  combination  products.  The  process  of  obtaining  regulatory  approvals  in  the  U.S.  and  in  foreign  countries  and
jurisdictions, and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations, require the expenditure of substantial time and
financial resources.

We and our third-party manufacturers, distributors and contract research organizations, or CROs, may also be subject to government regulation under other
federal, state, and local laws, including the U.S. Foreign Corrupt Practices Act, the Occupational Safety and Health Act, the Environmental Protection Act, the Clean Air
Act, the Health Insurance Portability and Accountability Act, privacy laws and import, export and customs regulations, as well as comparable laws and regulations of
other countries.

U.S. Government Regulation

In the U.S., the FDA, under the authorities granted to the agency by the Federal Food, Drug and Cosmetic Act, or FDCA, and its implementing regulations,
subjects  pharmaceutical  and  other  regulated  medical  products  to  rigorous  premarket  review  as  well  as  post-marketing  oversight  and  potential  enforcement  actions.
Failure to comply with applicable U.S. requirements at any time during the product development or approval process, or after approval, may subject a company to a
variety  of  administrative  or  judicial  sanctions  brought  by  the  FDA  and  the  Department  of  Justice,  or  DOJ,  or  other  governmental  entities,  any  of  which  could  have  a
material adverse effect on us. These sanctions could include:

refusal to approve pending or future marketing applications;

•
• warning or untitled letters;
• withdrawal of an approval;
•
•
•
•
•

imposition of a clinical hold;
voluntary product recalls;
seizures or administrative detention of product;
total or partial suspension of production or distribution; or
injunctions, fines, disgorgement, civil penalties or criminal prosecution.

FDA Approval Process for Prescription Drugs

To obtain approval of a new drug product from the FDA, we must, among other requirements, submit extensive data supporting its safety and efficacy, as well
as  detailed  information  on  the  manufacture  and  composition  of  the  drug  and  proposed  product  labeling  and  packaging.  The  testing  and  collection  of  data  and  the
preparation  of  necessary  applications  are  expensive  and  time-consuming.  The  FDA  may  not  act  quickly  or  favorably  in  reviewing  these  applications,  and  we  may
encounter significant difficulties or costs in our efforts to obtain FDA approvals that could delay or preclude us from marketing our product candidates.

The process required by the FDA before a new drug may be marketed in the U.S. generally involves some or all of the following key steps:

•

•

•

•

•

completion  of  nonclinical  studies,  such  as  laboratory  tests,  potentially  animal  studies,  and  formulation  studies,  performed  in  compliance  with  FDA
regulations for good laboratory practices, or GLPs, and other applicable regulations;

design of a clinical protocol and its submission to the FDA as part of an IND, which must become effective before human clinical trials may begin;

performance of adequate and well-controlled human clinical trials according to good clinical practices, or GCPs, to establish the safety and efficacy of the
product candidate for its intended use;

submission of an NDA to the FDA along with payment of the application user fee and FDA acceptance of that NDA;

satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities at which the active pharmaceutical ingredient, or API, and finished
drug product are produced and tested to assess readiness for commercial manufacturing and conformance to the manufacturing-related elements of the
application, to conduct a data integrity audit, and to assess compliance with current good manufacturing

29

practices, or cGMP, in order to assure that the facilities, methods and controls are adequate to preserve the drug candidate’s identity, strength, quality and
purity;

possible inspection of selected clinical study sites to confirm compliance with GCP requirements and data integrity; and

FDA review and approval of the NDA, including satisfactory completion of an FDA advisory committee review of the product candidate, if applicable, which
must occur prior to any commercial marketing or sale of the drug product in the U.S.

•

•

Preclinical Studies

After a therapeutic candidate is identified for development, it enters the preclinical or nonclinical testing stage. Preclinical studies include laboratory evaluation
of product chemistry, toxicity and formulation, as well as animal studies to assess potential safety and efficacy. The Consolidated Appropriations Act for 2023, signed
into law on December 29, 2022, (P.L. 117-328) amended the FDCA to specify that nonclinical testing for drugs may, but is not required to, include in vivo animal testing.
According to the amended language, a sponsor may fulfill nonclinical testing requirements by completing various in vitro assays (e.g., cell-based assays, organ chips, or
microphysiological  systems),  in  silico  studies  (i.e.,  computer  modeling),  other  human  or  non-human  biology-based  tests  (e.g.,  bioprinting),  or  in  vivo  animal  tests.
Nonclinical tests intended for submission to the FDA to support the safety of a product candidate must be conducted in compliance with GLP regulations and the United
States  Department  of  Agriculture’s  Animal  Welfare  Act,  if  applicable.  A  drug  sponsor  must  submit  the  results  of  the  preclinical  tests,  together  with  manufacturing
information, analytical data and any available clinical data or literature, among other things, to the FDA as part of an IND. Some nonclinical testing may continue after
the IND is submitted. In addition to including the results of the nonclinical studies, the IND will include one or more clinical protocols detailing, among other things, the
objectives of the clinical trial and the safety and effectiveness criteria to be evaluated.

An IND automatically becomes effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to one or more
proposed clinical trials and places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the
clinical trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence. A clinical hold may occur at any time during the
life of an IND and may affect one or more specific studies or all studies conducted under the IND. Occasionally, clinical holds are imposed due to manufacturing issues
that may present safety issues for the clinical study subjects.

Human Clinical Trials in Support of an NDA

The clinical investigation of an investigational new drug is divided into three phases that typically are conducted sequentially but may overlap or be combined.

The three phases are as follows:

Phase 1. Phase 1 includes initial clinical trials introducing an investigational new drug into humans and may be conducted in subjects with the target disease or
healthy volunteers. These trials are designed to determine the metabolism and pharmacologic actions of the drug in humans, the side effects associated with increasing
doses, and, if possible, to gain early evidence on effectiveness.

Phase 2. Phase 2 includes the controlled clinical trials conducted to evaluate the effectiveness of the drug candidate for a particular indication or indications in
subjects with the disease or condition under study and to determine the common short-term side effects and risks associated with the drug. Phase 2 trials are typically
well controlled, closely monitored, and conducted in a relatively small number of subjects.

Phase 3. Phase 3 trials are typically large trials performed after preliminary evidence suggesting effectiveness of the drug candidate has been obtained. They
are intended to gather additional information about the effectiveness and safety that is needed to evaluate the overall benefit-risk relationship of the drug and to provide
an adequate basis for physician labeling and product marketing approval. Phase 3 trials usually are conducted at geographically dispersed clinical study sites.

A clinical trial may combine the elements of more than one phase and the FDA often requires more than one Phase 3 trial to support marketing approval of a
product candidate. A company’s designation of a clinical trial as being of a particular phase is not necessarily indicative that the study will be sufficient to satisfy the FDA
requirements of that phase because this determination cannot be made until the protocol and data have been submitted to and reviewed by the FDA. Human clinical
trials are inherently uncertain and Phase 1, Phase 2 and Phase 3 testing may not be successfully completed.

30

A pivotal trial is a clinical trial that is believed to satisfy FDA requirements for the evaluation of a product candidate’s safety and efficacy such that it can be
used, alone or with other pivotal or non-pivotal trials, to support regulatory approval. Generally, pivotal trials are Phase 3 trials, but they may be Phase 2 trials if the
design provides a well-controlled and reliable assessment of clinical benefit, particularly in an area of unmet medical need. Congress also recently amended the FDCA,
as  part  of  the  Consolidated  Appropriations  Act  for  2023,  in  order  to  require  sponsors  of  a  Phase  3  clinical  trial,  or  other  “pivotal  study”  of  a  new  drug  to  support
marketing authorization, to design and submit a diversity action plan for such clinical trial. The action plan must include the sponsor’s diversity goals for enrollment, as
well as a rationale for the goals and a description of how the sponsor will meet them. Sponsors must submit a diversity action plan to the FDA by the time the sponsor
submits  the  relevant  clinical  trial  protocol  to  the  agency  for  review.  The  FDA  may  grant  a  waiver  for  some  or  all  of  the  requirements  for  a  diversity  action  plan.  It  is
unknown at this time how the diversity action plan may affect Phase 3 trial planning and timing or what specific information FDA will expect in such plans, but if the FDA
objects to a sponsor’s diversity action plan or otherwise requires significant changes to be made, it could delay initiation of the relevant clinical trial.

Clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with the FDA’s GCP requirements. They must be
conducted  under  protocols  detailing  the  objectives  of  the  trial,  dosing  procedures,  research  subject  selection  and  exclusion  criteria  and  the  safety  and  effectiveness
criteria to be evaluated. Each protocol, and any subsequent material amendment to the protocol, must be submitted to the FDA as part of the IND, and progress reports
detailing the status of the clinical trials must be submitted to the FDA annually. Sponsors also must report to the FDA serious and unexpected adverse reactions in a
timely  manner,  any  clinically  important  increase  in  the  rate  of  a  serious  suspected  adverse  reaction  over  that  listed  in  the  protocol  or  investigation  brochure  or  any
findings from other studies or animal or in vitro testing that suggest a significant risk in humans exposed to the product or therapeutic candidate. The FDA may order the
temporary  or  permanent  discontinuation  of  a  clinical  trial  at  any  time,  via  a  clinical  hold,  or  impose  other  sanctions  if  it  believes  that  the  clinical  trial  is  not  being
conducted  in  accordance  with  FDA  requirements  or  that  the  subjects  are  being  exposed  to  an  unacceptable  health  risk.  An  institutional  review  board,  or  IRB,  is
responsible for ensuring that human subjects in clinical studies are protected from inappropriate study risks. An IRB at each institution participating in the clinical trial
must review and approve the protocol before a clinical trial commences at that institution and must also approve the information regarding the trial and the consent form
that must be provided to each research subject or the subject’s legal representative, monitor the trial until completed and otherwise comply with IRB regulations. The
IRB  also  may  halt  a  study,  either  temporarily  or  permanently,  for  failure  to  comply  with  GCP  or  the  IRB’s  requirements,  or  if  the  investigational  new  drug  has  been
associated with unexpected serious harm to patients.

During  the  development  of  a  new  drug  product  candidate,  sponsors  are  given  opportunities  to  meet  with  the  FDA  at  certain  points;  specifically,  prior  to  the
submission of an IND, at the end of Phase 2 and before an NDA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity
for the sponsor to share information about the data gathered to date and for the FDA to provide advice on the next phase of development. Sponsors typically use the
meeting  at  the  end  of  Phase  2  to  discuss  their  Phase  2  clinical  results  and  present  their  plans  for  the  pivotal  Phase  3  clinical  trial  that  they  believe  will  support  the
approval of the new therapeutic.

Post-approval trials, sometimes referred to as “Phase 4” clinical trials, may be conducted after initial marketing approval. These trials are used to gain additional

experience from the treatment of patients in the intended therapeutic indication. In certain instances, FDA may mandate the performance of “Phase 4” clinical trials.

Concurrent  with  clinical  trials,  sponsors  usually  complete  additional  animal  safety  studies,  develop  additional  information  about  the  chemistry  and  physical
characteristics  of  the  product  candidate  and  finalize  a  process  for  manufacturing  commercial  quantities  of  the  product  candidate  in  accordance  with  cGMP
requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other criteria, the sponsor
must develop methods for testing the identity, strength, quality, and purity of the finished drug product. Additionally, appropriate packaging must be selected and tested,
and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

Marketing Application Submission and FDA Review

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, detailed information on the product candidate
is submitted to the FDA in the form of an NDA requesting approval to market the drug for one or more indications. An NDA includes all relevant data available from
pertinent nonclinical studies and clinical trials, including negative or ambiguous results as well as positive findings, together with detailed information on the product
candidate’s chemistry, manufacturing, and controls, or CMC, and proposed

31

labeling,  among  other  things.  To  support  marketing  approval,  the  data  submitted  must  be  sufficient  in  quality  and  quantity  to  establish  the  safety  and  efficacy  of  the
product candidate for its intended use to the satisfaction of the FDA.

Under the Prescription Drug User Fee Act, or PDUFA, each NDA must be accompanied by a significant user fee. The FDA adjusts the PDUFA user fees on an
annual basis. PDUFA also imposes an annual program fee for marketed prescription drug products. Fee waivers or reductions are available in certain circumstances,
such  as  where  a  waiver  is  necessary  to  protect  the  public  health,  where  the  fee  would  present  a  significant  barrier  to  innovation,  or  where  the  applicant  is  a  small
business submitting its first human therapeutic application for review.

Under the goals and policies agreed to by the FDA under PDUFA, the FDA has ten months from receipt in which to complete its initial review of a standard NDA
for a drug that is not a new molecular entity, and six months from the receipt date for an application with priority review. The FDA does not always meet its PDUFA goal
dates, and the review process is often significantly extended by FDA requests for additional information or clarification and the sponsor’s process to respond to such
inquiries.  As  a  result,  the  NDA  review  process  can  be  very  lengthy.  Most  innovative  drug  products  (other  than  biological  products)  obtain  FDA  marketing  approval
pursuant  to  an  NDA  submitted  under  Section  505(b)(1)  of  the  FDCA,  commonly  referred  to  as  a  traditional  or  "full  NDA."  In  1984,  with  passage  of  the  Drug  Price
Competition and Patent Term Restoration Act, informally known as the Hatch-Waxman Act, that established an abbreviated regulatory scheme authorizing the FDA to
approve  generic  drugs  based  on  an  innovator  or  “reference”  product,  Congress  also  enacted  Section  505(b)(2)  of  the  FDCA,  which  provides  a  hybrid  pathway
combining features of a traditional NDA and a generic drug application. Section 505(b)(2) enables the applicant to rely, in part, on the FDA’s prior findings of safety and
efficacy data for an existing product, or published literature, in support of its application. Section 505(b)(2) NDAs may provide an alternate path to FDA approval for new
or improved formulations or new uses of previously approved products; for example, an applicant may be seeking approval to market a previously approved drug for
new indications or for a new patient population that would require new clinical data to demonstrate safety or effectiveness. Section 505(b)(2) permits the filing of an
NDA in which the applicant relies, at least in part, on information from studies made to show whether a drug is safe or effective that were not conducted by or for the
applicant and for which the applicant has not obtained a right of reference or use. A Section 505(b)(2) applicant may eliminate or reduce the need to conduct certain
pre-clinical or clinical studies, if it can establish that reliance on studies conducted for a previously-approved product is scientifically appropriate. The FDA may also
require companies to perform additional studies or measurements, including nonclinical and clinical studies, to support the change from the approved product. The FDA
may then approve the new product candidate for all or some of the labeled indications for which the referenced product has been approved, as well as for any new
indication for which the Section 505(b)(2) NDA applicant has submitted data.

The  FDA  conducts  a  preliminary  review  of  all  NDAs  it  receives,  whether  submitted  under  Section  505(b)(1)  or  Section  505(b)(2),  to  ensure  that  they  are
sufficiently complete for substantive review before it accepts them for filing. The FDA may refuse to file any NDA that it deems incomplete or not properly reviewable at
the time of submission, and may request additional information rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional
information. The resubmitted application also is subject to review before the FDA accepts it for filing. The FDA has 60 days after submission of an NDA to conduct an
initial review to determine whether it is sufficient to accept for filing. If the submission is accepted for filing, the FDA begins an in-depth substantive review of the NDA.
The  FDA  reviews  the  NDA  to  determine,  among  other  things,  whether  the  proposed  product  is  safe  and  effective  for  its  intended  use,  whether  it  has  an  acceptable
purity profile and whether the product is being manufactured in accordance with cGMP. During its review of an NDA, the FDA may refer the application to an advisory
committee of independent experts for a recommendation as to whether the application should be approved. An advisory committee is a panel of independent experts,
including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under
what conditions. The FDA is not bound by the recommendation of an advisory committee, but it typically follows such recommendations. Data from clinical trials are not
always conclusive, and the FDA or its advisory committee may interpret data differently than the NDA sponsor interprets the same data. The FDA may also re-analyze
the clinical trial data, which could result in extensive discussions between the FDA and the applicant during the review process.

Before  approving  an  NDA,  the  FDA  will  typically  inspect  the  facilities  at  which  the  product  is  manufactured.  The  FDA  will  not  approve  the  product  unless  it
determines  that  the  manufacturing  processes  and  facilities  are  in  compliance  with  cGMP  requirements  and  adequate  to  assure  consistent  production  of  the  product
within  required  specifications.  Additionally,  before  approving  the  NDA,  the  FDA  will  typically  inspect  one  or  more  clinical  sites  to  assure  that  the  clinical  trials  were
conducted in compliance with IND trial requirements and GCP requirements and to assure the integrity of the clinical data submitted to the FDA. To ensure cGMP and
GCP compliance by its employees and third-party contractors, an applicant must incur significant expenditure of time, money and effort in the areas of training, record
keeping, production and quality control.

32

The FDA also may require the submission of a risk evaluation and mitigation strategy, or REMS, plan if it determines that a REMS is necessary to ensure that
the benefits of the drug outweigh its risks and to assure the safe use of the product. The REMS plan could include medication guides, physician communication plans,
assessment plans and/or elements to assure safe use, such as restricted distribution methods, patient registries or other risk minimization tools. The FDA determines
the requirement for a REMS, as well as the specific REMS provisions, on a case-by-case basis. If the FDA concludes a REMS plan is needed, the sponsor of the NDA
must submit a proposed REMS plan. The FDA will not approve an NDA without a REMS plan, if required.

After  evaluating  the  NDA  and  all  related  information,  including  the  advisory  committee  recommendation,  if  any,  and  inspection  reports  regarding  the
manufacturing facilities where the drug product or its API will be produced and the clinical trial sites, the FDA will either issue an approval letter or, in some cases, a
complete response letter, or CRL, that describes all of the specific deficiencies in the NDA identified by the agency. An approval letter authorizes commercial marketing
of the drug product with specific prescribing information for specific indications. A CRL indicates that the review cycle of the application is complete and the application
will not be approved in its present form. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional
clinical  trials.  Additionally,  the  CRL  may  include  recommended  actions  that  the  applicant  might  take  to  place  the  application  in  a  condition  for  approval.  If  a  CRL  is
issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, or withdraw the application. If and when those deficiencies
have  been  addressed  to  the  FDA’s  satisfaction  in  a  resubmission  of  the  NDA,  the  FDA  will  issue  an  approval  letter  to  the  applicant.  The  FDA  has  committed  to
reviewing such resubmissions in response to an issued CRL in either two or six months depending on the type of information included. Even with the submission of this
additional information, the FDA nevertheless may ultimately decide that the NDA does not satisfy the regulatory criteria for approval.

Even if a drug product receives regulatory approval, the approval may be significantly limited to specific indications and dosages or the indications for use may
otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be
included  in  the  product  labeling.  The  FDA  may  impose  restrictions  and  conditions  on  product  distribution,  prescribing,  or  dispensing  in  the  form  of  a  REMS  plan,  or
otherwise limit the scope of any approval. In addition, the FDA may require post marketing clinical trials, sometimes referred to as “Phase 4” clinical trials, designed to
further  assess  a  product’s  safety  and  effectiveness,  and/or  testing  and  surveillance  programs  to  monitor  the  safety  of  approved  products  that  have  been
commercialized.  After  approval,  some  types  of  changes  to  the  approved  product,  such  as  adding  new  indications,  manufacturing  changes  and  additional  labeling
claims, are subject to further testing requirements and FDA review and approval.

Special FDA Programs to Facilitate and Expedite Development and Review of Certain New Drugs

The  FDA  is  authorized  to  designate  certain  products  for  expedited  development  or  review  if  they  are  intended  to  address  an  unmet  medical  need  in  the
treatment  of  a  serious  or  life-threatening  disease  or  condition.  These  programs  include,  but  are  not  limited  to,  fast  track  designation,  QIDP  designation,  and  priority
review designation. The purpose of these programs is to provide important new drugs to patients earlier than could occur under standard FDA procedures for interacting
with and responding to product sponsors during development and regulatory review.

To  be  eligible  for  a  fast  track  designation,  the  FDA  must  determine,  based  on  the  request  of  a  sponsor,  that  a  product  is  intended  to  treat  a  serious  or  life
threatening disease or condition and demonstrates the potential to address an unmet medical need by providing a therapy where none exists or a therapy that may be
potentially superior to existing therapy based on efficacy or safety factors. A drug that is designated as a qualified infectious disease product (“QIDP”) is also eligible for
fast  track  status.  Fast  track  designation  provides  opportunities  for  more  frequent  interactions  with  the  FDA  review  team  to  expedite  development  and  review  of  the
product. The FDA may also review sections of the NDA for a fast track product on a rolling basis before the complete application is submitted, if the sponsor and the
FDA agree on a schedule for the submission of the application sections, and the sponsor pays any required user fees upon submission of the first section of the NDA.
The FDA may decide to rescind the fast track designation if it determines that the qualifying criteria no longer apply. In addition, fast track designation may be withdrawn
by the sponsor or rescinded by the FDA if the designation is no longer supported by data emerging in the clinical trial process.

The Food and Drug Administration Safety and Innovation Act of 2012, or FDASIA, included the Generating Antibiotics Incentives Now Act, or the GAIN Act,
which directed FDA to implement QIDP designation program. The GAIN Act created incentives for the development of antibacterial and antifungal drug products for the
treatment of serious or life-threatening infections. A therapeutic candidate designated as a QIDP is eligible for fast track designation, and the first marketing application
submitted for a specific drug product and indication for which QIDP designation was granted will be granted priority review. A subsequent application from the same
sponsor for the same

33

product  and  indication  will  receive  priority  review  designation  only  if  it  otherwise  meets  the  criteria  for  priority  review.  As  discussed  further  below  under  “New  Drug
Marketing Exclusivity under the Hatch-Waxman Act Amendments & GAIN Exclusivity Extension - Qualified Infectious Disease Product Exclusivity,” the GAIN Act also
provides  the  possibility  of  a  five-year  exclusivity  extension  that  is  added  to  any  other  marketing  exclusivity  for  which  a  QIDP-designated  drug  qualifies  upon  FDA
approval.

Finally,  the  FDA  may  designate  a  product  for  priority  review  if  it  is  a  drug  that  treats  a  serious  condition  and,  if  approved,  would  provide  a  significant
improvement in safety or effectiveness. The FDA determines at the time that the marketing application is submitted, on a case-by-case basis, whether the proposed
drug represents a significant improvement in treatment, prevention or diagnosis of disease when compared with other available therapies. Significant improvement may
be  illustrated  by  evidence  of  increased  effectiveness  in  the  treatment  of  a  condition,  elimination  or  substantial  reduction  of  a  treatment-limiting  drug  reaction,
documented enhancement of patient compliance that may lead to improvement in serious outcomes, or evidence of safety and effectiveness in a new subpopulation. A
priority review designation is intended to direct overall attention and resources to the evaluation of such applications, and to shorten the FDA’s goal for taking action on
a marketing application from ten months to six months.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or
decide that the time period for FDA review or approval will not be shortened. Furthermore, fast track designation, QIDP designation, and priority review do not change
the standards for marketing approval and may not ultimately expedite the development or approval process.

From  time  to  time,  new  legislation  and  regulations  may  be  implemented  that  could  significantly  change  the  statutory  provisions  governing  the  approval,
manufacturing  and  marketing  of  products  regulated  by  the  FDA.  It  is  impossible  to  predict  whether  further  legislative  or  regulatory  changes  will  be  enacted,  or  FDA
regulations, guidance or interpretations changed or what the impact of such changes, if any, may be.

Post-Approval Requirements for Prescription Drugs

Following approval of a new drug product, the manufacturer and the approved drug are subject to pervasive and continuing regulation by the FDA, including,
among  other  things,  monitoring  and  recordkeeping  activities,  reporting  of  adverse  experiences  with  the  product,  product  sampling  and  distribution  restrictions,
complying with promotion and advertising requirements, which include restrictions on promoting drugs for unapproved uses or patient populations (i.e., “off-label use”)
and limitations on industry-sponsored scientific and educational activities. Although physicians may prescribe legally available products for off-label uses, manufacturers
may  not  market  or  promote  such  uses.  The  FDA  and  other  agencies  actively  enforce  the  laws  and  regulations  prohibiting  the  promotion  of  off-label  uses,  and  a
company that is found to have improperly promoted off-label uses may be subject to significant liability.

Moreover, if there are any modifications to the product, including changes in indications, labeling or manufacturing processes or facilities, the applicant may be
required to submit and obtain FDA approval of a new NDA or an NDA supplement, which may require the applicant to develop additional data or conduct additional
preclinical studies and clinical trials. In particular, securing FDA approval for new indications is similar to the process for approval of the original indication and requires,
among other things, submitting data from adequate and well-controlled clinical trials to demonstrate the product’s safety and efficacy in the new indication. Even if such
trials are conducted, the FDA may not approve any expansion of the labeled indications for use in a timely fashion, or at all.

In addition, FDA regulations require that products be manufactured in specific approved facilities and in accordance with cGMP. The cGMP regulations include
requirements relating to organization of personnel, buildings and facilities, equipment, control of components and drug product containers and closures, production and
process  controls,  packaging  and  labeling  controls,  holding  and  distribution,  laboratory  controls,  records  and  reports  and  returned  or  salvaged  products.  Drug
manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and some
state agencies, and are subject to periodic unannounced inspections by the FDA for compliance with cGMP and other requirements. Changes to the manufacturing
process, specifications or container closure system for an approved drug product are strictly regulated and often require prior FDA approval before being implemented.
FDA  regulations  also  require,  among  other  things,  the  investigation  and  correction  of  any  deviations  from  cGMP  and  the  imposition  of  reporting  and  documentation
requirements  upon  the  NDA  sponsor  and  any  third-party  manufacturers  involved  in  producing  the  approved  drug  product.  Accordingly,  both  sponsors  and
manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance and other aspects of quality
control and quality assurance, and to ensure ongoing compliance with other statutory requirements of the FDCA, such as the requirements for making manufacturing
changes to an approved NDA.

34

Accordingly, even after a new drug approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not
maintained  or  if  problems  occur  after  the  product  reaches  the  market.  Later  discovery  of  previously  unknown  problems  with  a  product,  including  adverse  events  of
unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling
to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or the imposition of distribution or other restrictions under a
REMS plan. Other potential consequences of regulatory non-compliance include, among other things:

•

•

•

•

•

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market or product recalls;

fines, warning letters or other enforcement-related letters or clinical holds on post-approval clinical trials;

refusal of the FDA to approve pending NDAs or supplements to approved NDAs;

product seizure or detention, or refusal to permit the import or export of products;

injunctions or the imposition of civil or criminal penalties;

consent decrees, corporate integrity agreements, debarment, or exclusion from federal health care programs; or

• mandated modification of promotional materials and labeling and the issuance of corrective information.

In  addition,  the  distribution  of  prescription  pharmaceutical  products  is  subject  to  a  variety  of  federal  and  state  laws.  The  Prescription  Drug  Marketing  Act  of
1987, or PDMA, was the first federal law to set minimum standards for the registration and regulation of drug distributors by the states and to regulate the distribution of
drug  samples.  Today,  both  the  PDMA  and  state  laws  limit  the  distribution  of  prescription  pharmaceutical  product  samples  and  impose  requirements  to  ensure
accountability in distribution. More recently, the Drug Supply Chain Security Act, or DSCSA, was enacted with the aim of building an electronic system to identify and
trace certain prescription drugs distributed in the United States. The DSCSA mandates phased-in and resource-intensive obligations for pharmaceutical manufacturers,
repackagers, wholesale distributors, and dispensers (primarily pharmacies) over a 10-year period that culminated in November 2023. It also replaced certain provisions
from  the  PDMA  pertaining  to  wholesale  distribution  of  prescription  drugs  with  a  more  comprehensive  statutory  scheme,  requiring  uniform  national  standards  for
wholesale distribution and, for the first time, for third-party logistics providers. In February 2022, the FDA released proposed regulations to amend the existing national
standards  for  licensing  of  wholesale  drug  distributors  by  the  states  (which  had  been  promulgated  under  the  PDMA);  to  establish  new  minimum  standards  for  state
licensing  third-party  logistics  providers;  and  to  create  a  federal  system  for  licensure  for  use  in  the  absence  of  a  state  program,  each  of  which  is  mandated  by  the
DSCSA.  Most  recently,  the  FDA  announced  a  one-year  stabilization  period  to  November  2024,  giving  entities  subject  to  the  DSCSA  additional  time  to  finalize
interoperable tracking systems and to ensure supply chain continuity. From time to time, new legislation and regulations may be implemented that could significantly
change the statutory provisions governing the approval, manufacturing, and marketing of prescription drug products regulated by the FDA.

FDA Review and Approval of Medical Devices

Medical  devices  also  are  strictly  regulated  by  the  FDA  in  the  United  States.  Under  the  FDCA,  a  medical  device  is  defined  as  “an  instrument,  apparatus,
implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component, part or accessory which is, among other things:
intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals; or intended to
affect the structure or any function of the body of man or other animals, and which does not achieve its primary intended purposes through chemical action within or on
the  body  of  man  or  other  animals  and  which  is  not  dependent  upon  being  metabolized  for  the  achievement  of  any  of  its  primary  intended  purposes.”  This  definition
provides a clear distinction between a medical device and other FDA-regulated products such as drugs. If the primary intended use of a medical product is achieved
through chemical action or by being metabolized by the body, the product is usually a drug or biologic. If not, it is generally a medical device.

Unless  an  exemption  applies,  a  new  medical  device  may  not  be  marketed  in  the  United  States  unless  and  until  it  has  been  cleared  through  the  premarket
notification, or 510(k), process, or approved by the FDA pursuant to a PMA. The information that must be submitted to the FDA in order to obtain clearance or approval
to  market  a  new  medical  device  varies  depending  on  how  the  medical  device  is  classified  by  the  FDA.  As  electronic  and  digital  medical  devices  have  become
increasingly  connected  to  the  internet,  hospital  networks,  and  other  medical  devices  to  provide  features  that  improve  health  care  and  patient  accessibility,  FDA  and
other regulatory authorities have recognized that those same features also increase the risk of potential cybersecurity threats. These types of medical devices may be
vulnerable to security breaches, potentially impacting the safety and effectiveness of the device, and accordingly

35

device manufacturers are responsible for identifying cybersecurity risks and hazards associated with their products. In recent years, the FDA has increased its scrutiny
of this issue as part of the review and marketing authorization process for new medical devices; the agency also monitors reports of cybersecurity risks as part of its
post-marketing device surveillance activities. In addition, as part of the Consolidated Appropriations Act for 2023, Congress created new premarket requirements for
developers of “cyber devices,” defined as medical devices that include software, connect to the internet, and contain any technological features that could be vulnerable
to cybersecurity threats.

Medical devices are classified into one of three classes on the basis of the controls deemed by the FDA to be necessary to reasonably assure their safety and
effectiveness.  Class  I  devices  are  those  low  risk  devices  for  which  reasonable  assurance  of  safety  and  effectiveness  can  be  provided  by  adherence  to  the  FDA’s
general controls for medical devices, which include applicable portions of the FDA’s Quality System Regulation, or QSR; facility registration and product listing; reporting
of  adverse  medical  events  and  malfunctions;  and  appropriate,  truthful  and  non-misleading  labeling,  advertising  and  promotional  materials.  Most  Class  I  devices  are
exempt from premarket regulation; however, some Class I devices require premarket clearance by the FDA through the 510(k) process.

Class II devices are moderate risk devices and are subject to the FDA’s general controls, and any other special controls, such as performance standards, post-
market surveillance, and FDA guidelines, deemed necessary by the FDA to provide reasonable assurance of the devices’ safety and effectiveness. Premarket review
and  clearance  by  the  FDA  for  most  Class  II  devices  is  accomplished  through  the  510(k)  process,  although  some  Class  II  devices  are  exempt  from  the  510(k)
requirements.  To  obtain  510(k)  clearance,  a  sponsor  must  submit  to  the  FDA  a  premarket  notification  demonstrating  that  the  device  is  substantially  equivalent  to  a
device that is already legally marketed in the United States and for which a PMA was not required (i.e., a Class II device). The device to which the sponsor’s device is
compared  for  the  purpose  of  determining  substantial  equivalence  is  called  a  “predicate  device.”  The  FDA’s  goal  is  to  make  a  substantial  equivalence  determination
within 90 days of FDA’s receipt of the 510(k) application, but it often takes longer if the FDA requests additional information. Most 510(k)s do not require supporting data
from  clinical  trials,  but  such  data  is  typically  required  if  the  predicate  device  relied  in  part  on  clinical  trial  data  to  obtain  clearance.  After  a  device  receives  510(k)
clearance,  any  modification  that  could  significantly  affect  its  safety  or  effectiveness,  or  that  would  constitute  a  major  change  in  its  intended  use,  will  require  a  new
clearance or possibly a pre-market approval. Premarket notifications are subject to user fees, unless a specific exemption applies.

Class III devices are deemed by the FDA to pose the greatest risk to patients, such as life-sustaining or life-supporting devices, devices that present a potential
unreasonable risk of illness or injury, or, more generally, devices whose safety and effectiveness cannot be assured solely by the general controls and special controls
described above. All Class III devices must be reviewed and approved by the FDA through the PMA process. A PMA must be supported by extensive data including,
but not limited to, technical data, nonclinical studies, clinical trials, manufacturing and labeling to demonstrate to the FDA’s satisfaction the safety and effectiveness of
the device for its intended use. After a PMA is submitted and the FDA determines the application is sufficiently complete, the agency will accept it for filing and begin an
in-depth review of the submitted information. By statute, the FDA has 180 days to review the accepted application, although review of the application generally can take
between one and three years. During this review period, the FDA may request additional information or clarification of information already provided. Also during the
review period, an advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as
to the approvability of the device. Although the FDA is not bound by the advisory panel decision, it considers such recommendations when making final decisions on
approval.  In  addition,  the  FDA  will  conduct  a  preapproval  inspection  of  the  manufacturing  facility  to  ensure  compliance  with  the  QSR.  New  PMA  applications  or
supplements  are  also  required  for  product  modifications  that  affect  the  safety  and  efficacy  of  the  device.  PMA  (and  supplemental  PMAs)  are  subject  to  significantly
higher user fees than are 510(k) premarket notifications.

Novel medical device types that the FDA has not previously classified as Class I, II or III are automatically classified into Class III regardless of the level of risk
they ultimately pose to patients and/or users. The Food and Drug Administration Modernization Act of 1997 established a new route to market for low to moderate risk
medical  devices  that  are  automatically  placed  into  Class  III  due  to  the  absence  of  a  predicate  device,  called  the  “Request  for  Evaluation  of  Automatic  Class  III
Designation,” or the De Novo  classification  procedure.  This  procedure  allows  a  manufacturer  whose  novel  device  is  automatically  classified  into  Class  III  to  request
down-classification of its medical device into Class I or Class II based on a benefit-risk analysis demonstrating the device actually presents low or moderate risk, rather
than requiring the submission and approval of a PMA application. Prior to the enactment of FDASIA, a medical device could only be eligible for De Novo classification if
the manufacturer first submitted a 510(k) premarket notification and received a determination from the FDA that the device was not substantially equivalent. FDASIA
streamlined  the  De  Novo  classification  pathway  by  permitting  manufacturers  to  request  De  Novo  classification  directly  without  first  submitting  a  510(k)  premarket
notification to the FDA and receiving a not

36

substantially  equivalent  determination.  The  FDA  is  required  under  the  statute  to  classify  the  device  within  120  days  following  receipt  of  the  De  Novo  application
however, the most recent FDA premarket review goals state that in fiscal year 2023, FDA will attempt to issue a decision on 70% of all De Novo classification requests
received within 150 days of receipt. If the manufacturer seeks reclassification into Class II, the manufacturer must include a draft proposal for special controls that are
necessary  to  provide  a  reasonable  assurance  of  the  safety  and  effectiveness  of  the  medical  device.  In  addition,  the  FDA  may  reject  the  reclassification  petition  if  it
identifies a legally marketed predicate device that would be appropriate for a 510(k) or determines that the device is not low to moderate risk or that general controls
would  be  inadequate  to  control  the  risks  and  special  controls  cannot  be  developed.  De  Novo  classification  requests  are  also  subject  to  user  fees,  unless  a  specific
exemption applies.

Clinical trials are almost always required to support a PMA application and are sometimes required for a De Novo classification request or 510(k) premarket
notification. In order to conduct a clinical investigation involving human subjects for the purpose of demonstrating the safety and effectiveness of a medical device, an
investigator acting on behalf of the company must, among other things, apply for and obtain IRB approval of the proposed investigation. In addition, if the clinical study
involves a “significant risk” (as defined by the FDA) to human health, the company sponsoring the investigation must also submit and obtain FDA approval of an IDE. An
IDE  must  be  supported  by  appropriate  data,  such  as  animal  and  laboratory  testing  results,  showing  that  it  is  safe  to  test  the  device  in  humans  and  that  the  testing
protocol is scientifically sound. The IDE must be approved in advance by the FDA for a specified number of study participants, unless the product is deemed a non-
significant risk device and eligible for abbreviated IDE requirements. Generally, clinical trials for a significant risk device may begin once the IDE is approved by the FDA
and the study protocol and informed consent form are approved by a duly-appointed IRB at each clinical trial site. A diversity action plan will be required for most clinical
studies of investigational medical devices intended to support marketing authorization as a result of the December 2022 FDCA amendments.

FDA’s IDE regulations govern investigational device labeling, prohibit promotion, and specify an array of GCP requirements, which include, among other things,
recordkeeping, reporting and monitoring responsibilities of study sponsors and study investigators. Clinical trials must further comply with the FDA’s regulations for IRB
approval  and  for  informed  consent  and  other  human  subject  protections.  Required  records  and  reports  are  subject  to  inspection  by  the  FDA.  The  results  of  clinical
testing may be unfavorable or, even if the intended safety and efficacy success criteria are achieved, may not be considered sufficient for the FDA to grant approval or
clearance of a product.

Post-Marketing Requirements for Medical Devices

After  a  medical  device  is  placed  on  the  market,  numerous  regulatory  requirements  apply  that  in  some  ways  mirror  the  post-approval  requirements  for

prescription drugs. These include, but are not limited to:

•

•

•

•

•

•

submitting and updating establishment registration and device listings with the FDA;

compliance  with  the  QSR,  which  requires  manufacturers  to  follow  stringent  design,  testing,  control,  documentation,  record  maintenance,  including
maintenance of complaint and related investigation files, and other quality assurance controls during the manufacturing process;
pre-scheduled or unannounced device facility inspections by the FDA;

labeling  regulations,  which  prohibit  the  promotion  of  devices  for  uncleared  or  unapproved  (or  “off-label”)  uses  and  impose  other  restrictions  relating  to
promotional activities;

corrections and removal reporting regulations, which require that manufacturers report to the FDA field corrections or removals if undertaken to reduce a
risk to health posed by a device or to remedy a violation of the FDCA that may present a risk to health; and
post-market surveillance regulations, which apply to certain Class II or III devices when necessary to protect the public health or to provide additional safety
and effectiveness data for the device.

Under the FDA medical device reporting, or MDR, regulations, medical device manufacturers are required to report to the FDA information that a device has or
may  have  caused  or  contributed  to  a  death  or  serious  injury  or  has  malfunctioned  in  a  way  that  would  likely  cause  or  contribute  to  death  or  serious  injury  if  the
malfunction  of  the  device  or  a  similar  device  of  such  manufacturer  were  to  recur.  The  decision  to  file  an  MDR  involves  a  judgment  by  the  manufacturer.  If  the  FDA
disagrees with the manufacturer’s determination, the FDA can take enforcement action.

Additionally, the FDA has the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture.
The authority to require a recall must be based on an FDA finding that there is reasonable probability that the device would cause serious adverse health consequences
or death. Manufacturers may, under their own initiative, recall a product if any distributed devices fail to meet established specifications, are otherwise misbranded or
adulterated, or if any other material deficiency is found. The FDA requires that certain classifications of recalls be reported to the FDA within ten working days after the
recall is initiated.

37

As with prescription drugs, the failure to comply with applicable device regulatory requirements can result in enforcement action by the FDA, which may include

any of the following sanctions:

• warning letters, fines, injunctions or civil penalties;

•

•
•
•

recalls, detentions or seizures of products;

operating restrictions;
delays in the introduction of products into the market;
total or partial suspension of production;

delay or refusal of the FDA or other regulators to grant 510(k) clearance or PMA approvals of new or modified devices;

•
• withdrawals of marketing authorization; or
•

in the most serious cases, criminal prosecution.

To  ensure  compliance  with  regulatory  requirements,  medical  device  manufacturers  are  subject  to  market  surveillance  and  periodic,  prescheduled  or

unannounced inspections by the FDA, and these inspections may include the manufacturing facilities of subcontractors and third-party component suppliers.

FDA Review and Approval Process for Combination Products

A  combination  product  is  a  product  composed  of  a  combination  of  two  or  more  FDA-regulated  product  constituent  parts  or  products,  e.g.,  drug-device  or
biologic-device.  Such  products  often  raise  regulatory,  policy  and  review  management  challenges  because  they  integrate  constituent  parts  that  are  regulated  under
different types of regulatory requirements and by different FDA Centers, namely, the Center for Drug Evaluation and Research, or CDER, the Center for Devices and
Radiological Health, or CDRH, or the Center for Biologics Evaluation and Research, or CBER. Differences in regulatory pathways for each constituent part can impact
the  regulatory  processes  for  all  aspects  of  product  development  and  management,  including  preclinical  testing,  clinical  investigation,  marketing  applications,
manufacturing and quality control, adverse event reporting, promotion and advertising, and post-approval modifications. Specifically, under regulations issued by the
FDA, a combination product may be:

•

•

•

•

a product comprised of two or more regulated constituent parts that are physically, chemically, or otherwise combined or mixed and produced as a single
entity;

two or more separate products packaged together in a single package or as a unit and comprised of drug and device products;

a drug or device packaged separately that according to its investigational plan or proposed labeling is intended for use only with an approved individually
specified drug or device where both are required to achieve the intended use, indication, or effect and where upon approval of the proposed product the
labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form, strength, route of administration, or
significant change in dose; or

any  investigational  drug  or  device  packaged  separately  that  according  to  its  proposed  labeling  is  for  use  only  with  another  individually  specified
investigational drug, device, or biological product where both are required to achieve the intended use, indication, or effect.

The FDA’s Office of Combination Products, or OCP, was established to provide prompt determination of the FDA Center with primary jurisdiction over the review
and regulation of a combination product; ensure timely and effective premarket review by overseeing the timeliness of and coordinating reviews involving more than one
center; ensure consistent and appropriate post-market regulation; resolve disputes regarding review timeliness; and review/revise agreements, guidance and practices
specific to the assignment of combination products.

OCP determines which Center will have primary jurisdiction for the combination product, referred to as the Lead Center, based on the combination product’s
“primary mode of action,” or PMOA. A mode of action is the means by which a product achieves an intended therapeutic effect or action. The PMOA is the mode of
action that provides the most important therapeutic action of the combination product, or the mode of action expected to make the greatest contribution to the overall
intended therapeutic effects of the combination product. The Lead Center has primary responsibility for the review and regulation of a combination product; however a
second Center is often involved in the review process, especially to provide input regarding the “secondary” component(s). In most instances, the Lead Center applies
its  usual  regulatory  pathway.  For  example,  a  drug-device  combination  product  assigned  to  CDER  will  typically  be  reviewed  under  an  NDA,  while  a  drug-device
combination product assigned to CDRH is typically reviewed under through a 510(k), PMA, or De Novo classification request.

38

Often it is difficult for OCP to determine with reasonable certainty the most important therapeutic action of the combination product. In those difficult cases, OCP
will consider consistency with other combination products raising similar types of safety and effectiveness questions, or which Center has the most expertise to evaluate
the  most  significant  safety  and  effectiveness  questions  raised  by  the  combination  product.  A  sponsor  may  use  a  voluntary  formal  process,  known  as  a  Request  for
Designation, when the product classification is unclear or in dispute, to obtain a binding decision as to which Center will regulate the combination product. If the sponsor
objects to that decision, the sponsor may request that OCP reconsider its decision.

Combination products are subject to FDA user fees based on the type of application submitted for the product’s premarket approval or clearance. For example,
a combination product for which an NDA is submitted is subject to the NDA fee under PDUFA. Likewise, a combination product for which a PMA is submitted is subject
to the PMA fee under the Medical Device User Fee and Modernization Act.

Since a combination product incorporates two or more constituent parts that have different regulatory requirements, a combination product manufacturer must
comply  with  all  cGMP  and  QSR  requirements  that  apply  to  each  constituent  part.  The  FDA  has  issued  a  combination  product  cGMP  regulation,  along  with  final
guidance,  describing  two  approaches  a  combination  product  manufacturer  may  follow  to  demonstrate  compliance.  Under  these  two  options,  the  manufacturer
demonstrates compliance with: (1) All cGMP regulations applicable to each separate regulated constituent part included in the combination product; or (2) either the
drug cGMP or the QSR, as well as with specified provisions from the other of these two sets of requirements (also called the “streamlined approach”). In addition, The
21st  Century  Cures  Act,  or  the  Cures  Act,  which  became  law  in  December  2016  and,  among  other  things,  amended  provisions  of  the  FDCA,  clarified  that  for  drug-
device combination products with a device PMOA and an FDA-approved drug constituent part, Hatch-Waxman Act requirements apply. Accordingly, a potential patent
dispute  regarding  the  listed  drug  that  is  being  referenced  by  the  combination  product  sponsor  may  delay  the  marketing  authorization  of  the  combination  product.
Furthermore,  the  Cures  Act  amendments  applied  Hatch-Waxman  Act  exclusivity  provisions  (e.g.,  new  chemical  entity  and  new  clinical  investigation)  to  the  device
clearance and approval process for combination products with a device PMOA.

New Drug Marketing Exclusivity under the Hatch-Waxman Act Amendments & GAIN Exclusivity Extension

Orange Book Listing & Patent Certification

As noted above, Congress created the 505(b)(2) NDA pathway in 1984 as part of the Hatch-Waxman Act amendments to the FDCA. At the same time, it also
established  an  abbreviated  regulatory  scheme  authorizing  the  FDA  to  approve  generic  drugs  that  are  shown  to  contain  the  same  active  ingredients  as,  and  to  be
bioequivalent to, drugs previously approved by the FDA pursuant to NDAs. To obtain approval of a generic drug, an applicant must submit an abbreviated new drug
application,  or  ANDA,  to  the  agency.  An  ANDA  is  a  comprehensive  submission  that  contains,  among  other  things,  data  and  information  pertaining  to  the  active
pharmaceutical  ingredient,  bioequivalence,  drug  product  formulation,  specifications  and  stability  of  the  generic  drug,  as  well  as  analytical  methods,  manufacturing
process validation data and quality control procedures. ANDAs are “abbreviated” because they cannot include preclinical and clinical data to demonstrate safety and
effectiveness. Instead, in support of such applications, a generic manufacturer must rely on the preclinical and clinical testing previously conducted for a drug product
previously approved under an NDA, known as the reference listed drug, or RLD. Unlike the ANDA pathway, which does not allow applicants to submit new clinical data
other than bioavailability or bioequivalence data, the 505(b)(2) regulatory pathway does not preclude the possibility that a follow-on applicant would need to conduct
additional clinical trials or nonclinical studies to demonstrate safety or effectiveness of the proposed change(s) being made to a previously approved drug.

In  order  for  an  ANDA  to  be  approved,  the  FDA  must  find  that  the  generic  version  is  identical  to  the  RLD  with  respect  to  the  active  ingredients,  the  route  of
administration, the dosage form, the strength of the drug and the conditions of use of the drug. At the same time, the FDA must also determine that the generic drug is
“bioequivalent”  to  the  innovator  drug.  Under  the  statute,  a  generic  drug  is  bioequivalent  to  a  RLD  if  “the  rate  and  extent  of  absorption  of  the  drug  do  not  show  a
significant  difference  from  the  rate  and  extent  of  absorption  of  the  listed  drug.”  Upon  approval  of  an  ANDA,  the  FDA  indicates  whether  the  generic  product  is
“therapeutically equivalent” to the RLD in the Orange Book. Physicians and pharmacists consider a therapeutic equivalent generic drug to be fully substitutable for the
RLD.  In  addition,  by  operation  of  certain  state  laws  and  numerous  health  insurance  programs,  the  FDA’s  designation  of  therapeutic  equivalence  often  results  in
substitution of the generic drug without the knowledge or consent of either the prescribing physician or patient.

39

As part of the NDA review and approval process, applicants are required to list with the FDA each patent that has claims that cover the applicant’s product or
method of therapeutic use. Upon approval of a new drug, each of the patents listed in the application for the drug is then published in the Orange Book. Drugs listed in
the  Orange  Book  can,  in  turn,  be  cited  by  potential  follow-on  competitors  in  support  of  approval  of  an  ANDA  or  a  505(b)(2)  NDA  that  relies  in  full  or  in  part  on  the
reference product.

When an ANDA applicant submits its application to the FDA, it is required to certify to the FDA concerning any patents listed for the reference product in the
FDA’s Orange Book. Specifically, the ANDA applicant must certify that: (i) the required patent information has not been filed; (ii) the listed patent has expired; (iii) the
listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or (iv) the listed patent is invalid or will not be infringed by
the new product. Moreover, to the extent that the Section 505(b)(2) NDA applicant is relying on studies conducted for an already approved product, the applicant also is
required to certify to the FDA concerning any patents listed for the NDA-approved product in the Orange Book to the same extent that an ANDA applicant would.

If the follow-on applicant does not challenge the innovator’s listed patents, FDA will not approve the ANDA or 505(b)(2) application until all the listed patents
claiming the referenced product have expired. A certification that the new product will not infringe the already approved product’s listed patents, or that such patents are
invalid, is called a Paragraph IV certification. If the follow-on applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the
Paragraph IV certification to the NDA and patent holders once the ANDA or 505(b)(2) NDA has been accepted for filing by the FDA. The NDA and patent holders may
then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days of the
receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA or 505(b)(2) NDA until the earlier of 30 months, expiration of the patent,
settlement of the lawsuit, or a decision in the infringement case that is favorable to the ANDA/505(b)(2) applicant.

Non-Patent Exclusivity

An ANDA or 505(b)(2) NDA also will not be approved until any applicable non-patent exclusivities listed in the Orange Book for the referenced product have
expired. The Hatch-Waxman Act amendments to the FDCA provided a five-year period of non-patent data exclusivity within the United States to the first applicant to
gain approval of an NDA for a new chemical entity, or NCE. For the purposes of this provision, an NCE is a drug that contains no active moiety that has previously been
approved by the FDA in any other NDA. An active moiety is the molecule or ion responsible for the physiological or pharmacological action of the drug substance. In
cases where such NCE exclusivity has been granted, an ANDA or 505(b)(2) NDA may not be filed with the FDA until the expiration of five years unless the submission
is accompanied by a Paragraph IV certification, in which case the applicant may submit its application four years following the original product approval.

The FDCA also provides for a period of three years of data exclusivity if an NDA or NDA supplement includes reports of one or more new clinical investigations,
other than bioavailability or bioequivalence studies that were conducted or sponsored by the applicant, are deemed by the FDA to be essential to the approval of the
application  or  supplement.  This  three-year  exclusivity  period  often  protects  changes  to  a  previously  approved  drug  product,  such  as  new  indications,  dosage  forms,
route of administration or combination of ingredients. Three-year exclusivity would be available for a drug product that contains a previously approved active moiety,
provided the statutory requirement for a new clinical investigation is satisfied. Unlike five-year NCE exclusivity, an award of three-year exclusivity does not block the
FDA from accepting ANDAs or 505(b)(2) NDAs seeking approval for generic versions of the drug as of the date of approval of the original drug product; rather, this
three-year  exclusivity  covers  only  the  conditions  of  use  associated  with  the  new  clinical  investigations  and,  as  a  general  matter,  does  not  prohibit  the  FDA  from
approving follow-on applications for drugs containing the original active ingredient.

Five-year and three-year exclusivity also will not delay the submission or approval of a traditional NDA filed under Section 505(b)(1) of the FDCA; however, an
applicant submitting a traditional NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical
trials necessary to demonstrate safety and effectiveness.

40

Qualified Infectious Disease Product Exclusivity

Under the GAIN Act amendments to the FDCA, the FDA may designate a product as a QIDP for a specific use for which it is being studied, upon the written
request of a sponsor at any time prior to submission of a marketing application. In order to qualify for designation as a QIDP, the drug product candidate must qualify as
an  antibiotic  or  antifungal  drug  for  human  use  intended  to  treat  serious  or  life-threatening  infections,  including  those  caused  by  either  (i)  an  antibiotic  or  antifungal
resistant  pathogen,  including  novel  or  emerging  infectious  pathogens,  or  (ii)  a  so-called  “qualifying  pathogen”  found  on  a  list  of  potentially  dangerous,  drug-resistant
organisms established and maintained by the FDA. In addition to the expedited review benefits that a QIDP-designated drug candidate may be eligible for (described
above under “Special FDA Programs to Facilitate and Expedite Development and Review of Certain New Drugs”), such a drug that is approved for the use for which the
QIDP designation was granted will receive a five-year extension to any non-patent marketing exclusivity period for which the drug qualified upon approval, such as a
five-year  NCE  exclusivity  or  three-year  new  clinical  data  exclusivity.  This  so-called  GAIN  exclusivity  extension  is  not  available  to  a  QIDP-designated  drug  that  has
previously received the five-year extension period, such as when an applicant is seeking approval for a new indication or new strength for a marketed infectious disease
product.

Patent Term Extension

A patent claiming a prescription drug or medical device for which FDA approval is granted may be eligible for a limited patent term extension under the FDCA,
which permits a patent restoration of up to five years for patent term lost during product development and the FDA regulatory review provided that certain statutory and
regulatory requirements are met. The length of the patent term extension is related to the length of time the drug or medical device is under regulatory review while the
patent is in force. The restoration period granted on a patent covering a new FDA-regulated medical product is typically one-half the time between the date a clinical
investigation on human beings is begun and the submission date of an application for premarket approval of the product, plus the time between the submission date of
an application for approval of the product and the ultimate approval date. Patent term restoration cannot be used to extend the remaining term of a patent past a total of
14 years from the product’s approval date. Only one patent applicable to an approved drug product is eligible for the extension, and the application for the extension
must  be  submitted  prior  to  the  expiration  of  the  patent  in  question.  A  patent  that  covers  multiple  products  for  which  approval  is  sought  can  only  be  extended  in
connection  with  one  of  the  marketing  approvals.  The  U.S.  Patent  and  Trademark  Office  reviews  and  approves  the  application  for  any  patent  term  extension  or
restoration in consultation with the FDA.

Disclosure of Clinical Trial Information

Sponsors  of  clinical  trials  of  certain  FDA-regulated  products,  including  prescription  drugs  and  medical  devices,  are  required  to  register  and  disclose  certain
clinical  trial  information  on  a  public  registry  maintained  by  the  U.S.  National  Institutes  of  Health,  or  NIH.  In  particular,  information  related  to  the  product,  patient
population,  phase  of  investigation,  study  sites  and  investigators  and  other  aspects  of  the  clinical  trial  is  made  public  as  part  of  the  registration  of  the  clinical  trial.
Competitors may use this publicly available information to gain knowledge regarding the progress of development programs. Although sponsors are also obligated to
disclose the results of their clinical trials after completion, disclosure of the results can be delayed in some cases for up to two years after the date of completion of the
trial. Failure to timely register a covered clinical study or to submit study results as provided for in the law can give rise to civil monetary penalties and also prevent the
non-compliant party from receiving future grant funds from the federal government. The NIH’s Final Rule on ClinicalTrials.gov registration and reporting requirements
became effective in 2017, and the government has brought enforcement actions against clinical trial sponsors that fail to comply with such requirements.

Other U.S. Health Care Laws and Compliance Requirements

As  we  plan  to  commercialize  our  product  candidates,  if  approved,  we  are  subject  to  additional  health  care  statutory  and  regulatory  requirements  and
enforcement by federal government and the states and foreign governments in the jurisdictions in which we conduct our business. Health care providers, physicians
and  third-party  payors  play  a  primary  role  in  the  recommendation  and  prescription  of  any  product  candidates  for  which  we  may  obtain  marketing  approval.
Arrangements we may enter into with third-party payors or other customers expose us to broadly applicable fraud and abuse and other health care laws and regulations
that  constrain  the  business  or  financial  arrangements  and  relationships  through  which  we  market,  sell,  and  distribute  any  products  for  which  we  obtain  marketing
approval.

Violations of the fraud and abuse laws, or other health care laws, are punishable by criminal and civil sanctions, including, in some instances, the possibility of

exclusion from participation in federal and state health care

41

programs, (including Medicare and Medicaid), and corporate integrity agreements, which impose, among other things, rigorous operational and monitoring requirements
on  companies.  Similar  sanctions  and  penalties  also  may  be  imposed  upon  executive  officers  and  employees,  including  criminal  sanctions  against  executive  officers
under  the  so-called  “responsible  corporate  officer”  doctrine,  even  in  situations  where  the  executive  officer  did  not  intend  to  violate  the  law  and  was  unaware  of  any
wrongdoing. Given the penalties that may be imposed on companies and individuals if convicted, allegations of such violations often result in settlements even if the
company or individual being investigated admits no wrongdoing. Settlements often include significant civil sanctions, including fines and civil monetary penalties, and
corporate integrity agreements. If the government were to allege or convict us or our executive officers, employees or consultants of violating these laws, our business
could be harmed. In addition, private individuals have the ability to bring similar actions under some of the fraud and abuse laws described below. Our activities could be
subject to challenge for the reasons discussed above and due to the broad scope of these laws and extensive enforcement of them by law enforcement authorities.
Further, federal and state laws that require manufacturers to make reports on pricing and marketing information could subject us to penalty provisions.

These applicable health care industry laws include, among others, health care information and data privacy and security laws, transparency laws, and fraud and

abuse laws, such as:

•

•

•

•

The  federal  Anti-Kickback  Statute  prohibits,  among  other  things,  any  person  from  knowingly  and  willfully  offering,  providing,  soliciting  or  receiving
remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce either the referral of an individual, for an item or service or the purchasing
or ordering of a good or service, for which payment may be made under federal health care programs such as the Medicare and Medicaid programs. The
federal  Anti-Kickback  Statute  is  subject  to  evolving  interpretations.  In  the  past,  the  government  has  enforced  the  federal  Anti-Kickback  Statute  to  reach
large settlements with health care companies based on sham consulting and other financial arrangements with physicians. A person or entity does not need
to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert that a
claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil
False Claims Act;

The  federal  civil  and  criminal  false  claims  laws,  including  the  civil  False  Claims  Act,  and  civil  monetary  penalties  laws  prohibit,  among  other  things,  any
person or entity from knowingly presenting, or causing to be presented, a false, fictitious or fraudulent claim for payment to the U.S. government, knowingly
making, using, or causing to be made or used, a false record or statement material to a false or fraudulent claim to the U.S. government, or from knowingly
making a false statement to avoid, decrease or conceal an obligation to pay money to the U.S. government. Actions under these laws may be brought by
the  Attorney  General  or  as  a  qui  tam  action  by  a  private  individual  in  the  name  of  the  government.  The  federal  government  uses  these  laws,  and  the
accompanying  threat  of  significant  liability,  in  its  investigation  and  prosecution  of  pharmaceutical  and  biotechnology  companies  throughout  the  U.S.,  for
example, in connection with the promotion of products for unapproved uses and other allegedly unlawful sales and marketing practices;

The U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created new federal, civil and criminal statutes that prohibit among
other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any health care benefit program, including private third-party
payors,  knowingly  and  willfully  embezzling  or  stealing  from  a  health  care  benefit  program,  willfully  obstructing  a  criminal  investigation  of  a  health  care
offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in
connection with the delivery of or payment for health care benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does
not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

The Physician Payments Sunshine Act, enacted as part of the ACA (defined below), among other things, imposes reporting requirements on manufacturers
of  FDA-approved  drugs,  devices,  biologics  and  medical  supplies  covered  by  Medicare  or  Medicaid  to  report,  on  an  annual  basis,  to  the  Centers  for
Medicare & Medicaid Services, or CMS, information related to payments and other transfers of value to physicians (defined to include doctors, dentists,
optometrists,  podiatrists,  and  chiropractors),  certain  advanced  non-physician  health  care  practitioners,  and  teaching  hospitals,  as  well  as  ownership  and
investment interests held by physicians and their immediate family members in such manufacturers;

• HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and their respective implementing regulations

impose specified requirements relating to the privacy, security and electronic exchange of individually identifiable health information (called "protected

42

health information" under HIPAA) as well as requirements for notification to affected individuals and the government in the event of a breach. Among other
things, HITECH makes certain of HIPAA’s privacy and all of HIPAA's security standards directly applicable to “business associates,” defined as independent
contractors  or  agents  of  "covered  entities,"  or  organizations  subject  to  HIPAA  which  include  certain  health  care  providers,  health  plans,  and  health  care
clearinghouses.  Business  associates  create,  receive,  maintain  or  transmit  protected  health  information  in  connection  with  providing  a  service  for  or  on
behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and
created penalties for third parties that unlawfully acquire protected health information. HITECH also gave state attorneys general new authority to file civil
actions for damages or injunctions in federal courts to enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions; and

•

State and local laws which require the registration of pharmaceutical sales representatives.

The  majority  of  states  also  have  statutes  or  regulations  similar  to  the  aforementioned  federal  anti-kickback  and  false  claims  laws,  which  apply  to  items  and
services  reimbursed  under  Medicaid  and  other  state  programs,  or,  in  several  states,  apply  regardless  of  the  payor.  We  may  be  subject  to  state  laws  governing  the
privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus
expanding and complicating compliance requirements. In addition, we may be subject to reporting requirements under state transparency laws, as well as state laws
that  require  pharmaceutical  companies  to  comply  with  the  industry’s  voluntary  compliance  guidelines  and  the  applicable  compliance  guidance  promulgated  by  the
federal government that otherwise restricts certain payments that may be made to health care providers and entities.

To  the  extent  we  commercialize  or  co-promote  our  products,  if  approved,  and  because  such  products  could  be  reimbursed  under  federal  and  other
governmental health care programs, we have developed an appropriate compliance program, commensurate to the limited commercial activities in which we engage,
that establishes internal controls to facilitate adherence to the rules and health care program requirements. Although compliance programs and adherence thereto may
mitigate the risk of violation of and subsequent investigation and prosecution for violations of the laws described above, the risks cannot be eliminated entirely. Ensuring
that  our  current  and  future  business  arrangements  with  third  parties  comply  with  applicable  health  care  laws  and  regulations  could  involve  substantial  costs.  It  is
possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or case law
involving applicable fraud and abuse or other health care laws and regulations. Moreover, if any of the physicians or other health care providers or entities with whom
we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions
from government funded health care programs.

Coverage, Pricing, and Reimbursement

Sales of our drug and drug-device combination products, if approved, will depend, in part, on the extent to which the costs of our products will be covered by
third-party payors, such as government health care programs, private health insurers, managed health care providers, and other organizations. These third-party payors
are increasingly challenging drug prices and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and
efficacy. If these third-party payors do not consider our products to be cost-effective compared to other therapies, they may not cover our products after approval as a
benefit under their plans or, even if they do, the level of payment may not be sufficient to allow us to sell our products on a profitable basis.

Significant uncertainty exists as to the reimbursement status for newly approved prescription products, including coding, coverage and payment. Sales of any
products for which we obtain marketing approval will depend in part on coverage and adequate payment from third-party payors. There is no uniform policy requirement
for  coverage  and  reimbursement  for  prescription  products  among  third-party  payors  in  the  United  States;  therefore  coverage  and  reimbursement  for  prescription
products can differ significantly from payor to payor.

In  order  to  secure  coverage  and  reimbursement  for  any  product  that  might  be  approved  for  sale,  a  company  may  need  to  conduct  expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain FDA or other
comparable regulatory approvals. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Moreover,
eligibility for reimbursement does not imply that any product will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture,
sale and distribution. Interim payments for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Payment

43

rates  may  vary  according  to  the  use  of  the  product  and  the  clinical  setting  in  which  it  is  used,  may  be  based  on  payments  allowed  for  lower  cost  products  that  are
already  reimbursed  and  may  be  incorporated  into  existing  payments  for  other  services.  Net  prices  for  products  may  be  reduced  by  mandatory  discounts  or  rebates
required by third-party payors and by any future relaxation of laws that presently restrict imports of products from countries where they may be sold at lower prices than
in  the  United  States.  In  the  United  States,  third-party  payors  often  rely  upon  Medicare  coverage  policy  and  payment  limitations  in  setting  their  own  reimbursement
policies,  but  they  also  have  their  own  methods  and  approval  process  apart  from  Medicare  coverage  and  reimbursement  determinations.  One  third-party  payor’s
determination to provide coverage for a product does not assure that other payors will also provide coverage for the product.

Accordingly, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for
the use of our products to each payor separately, with no assurance that coverage and adequate payment will be applied consistently or granted at all. The process for
determining whether a payor will cover and how much it will reimburse a product may be separate from the process of seeking approval of the product or for setting the
price of the product. Even if reimbursement is provided, market acceptance of our products may be adversely affected if the amount of payment for our products proves
to be unprofitable for health care providers or less profitable than alternative treatments or if administrative burdens make our products less desirable to use.

Additionally, the containment of health care costs has become a priority of federal and state governments and the prices of drug products have been a focus in
this effort. For example, there have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring more transparency to
drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. In
August  2022,  President  Biden  signed  into  the  law  the  Inflation  Reduction  Act  of  2022,  or  the  IRA,  which  includes  (among  other  things)  multiple  provisions  that  may
impact the prices of drug products that are both sold into the Medicare program and throughout the United States. Starting in 2023, a manufacturer of drug products
covered by Medicare Parts B or D must pay a rebate to the federal government if their drug product’s price increases faster than the rate of inflation. This calculation is
made on a drug product by drug product basis and the amount of the rebate owed to the federal government is directly dependent on the volume of a drug product that
is paid for by Medicare Parts B or D. Additionally, starting for payment year 2026, CMS will negotiate drug prices annually for a select number of single source Part D
drugs without generic competition. CMS will also negotiate drug prices for a select number of Part B drugs starting for payment year 2028. If a drug product is selected
by CMS for negotiation, it is expected that the revenue generated from such drug will decrease. CMS has begun to implement these new authorities and entered into
the first set of agreements with pharmaceutical manufacturers to conduct price negotiations in October 2023. However, the IRA's impact on the pharmaceutical industry
in the United States remains uncertain, in part because multiple large pharmaceutical companies and other stakeholders (e.g., the U.S. Chamber of Commerce) have
initiated federal lawsuits against CMS arguing the program is unconstitutional for a variety of reasons, among other complaints. Those lawsuits are ongoing.

We expect that federal, state and local governments in the U.S. will continue to consider legislation directed at lowering the total cost of health care. Individual
states  in  the  United  States  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  product  pricing,  including  price  or
patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases,
designed to encourage importation from other countries and bulk purchasing. In December 2020, the U.S. Supreme Court held unanimously that federal law does not
preempt  the  states’  ability  to  regulate  pharmacy  benefit  managers,  or  PBMs,  and  other  members  of  the  health  care  and  pharmaceutical  supply  chain,  an  important
decision that appears to be leading to further and more aggressive efforts by states in this area. The Federal Trade Commission in mid-2022 also launched sweeping
investigations into the practices of the PBM industry that could lead to additional federal and state legislative or regulatory proposals targeting such entities’ operations,
pharmacy  networks,  or  financial  arrangements.  Significant  efforts  to  change  the  PBM  industry  as  it  currently  exists  in  the  U.S.  may  affect  the  entire  pharmaceutical
supply chain and the business of other stakeholders, including medical product developers like us.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, collectively referred to as the ACA,
enacted  in  March  2010,  has  had  and  is  expected  to  continue  to  have  a  significant  impact  on  the  health  care  industry.  The  ACA,  among  other  things,  imposes  a
significant annual fee on certain companies that manufacture or import branded prescription drug products. The ACA also increased the Medicaid rebate rate and the
volume  of  rebated  drugs  has  been  expanded  to  include  beneficiaries  in  Medicaid  managed  care  organizations.  The  ACA  also  expanded  the  340B  drug  discount
program (excluding orphan drugs), including a 50% discount on brand name drugs for Medicare Part D participants in the coverage gap, and revised the

44

definition  of  “average  manufacturer  price”  for  reporting  purposes,  which  could  increase  the  amount  of  the  Medicaid  drug  rebates  paid  to  states.  It  also  contains
substantial provisions intended to broaden access to health insurance, reduce or constrain the growth of health care spending, enhance remedies against health care
fraud and abuse, add new transparency requirements for the health care industry, impose new taxes and fees on pharmaceutical manufacturers, and impose additional
health policy reforms. Further legislative and regulatory changes under the ACA remain possible, although it is unknown what form any such changes or any law would
take, and how or whether it may affect the biopharmaceutical industry as a whole or our business in the future.

It  is  uncertain  whether  and  how  future  legislation  or  regulatory  changes  could  affect  prospects  for  our  product  candidates  or  what  actions  federal,  state,  or
commercial  payors  for  pharmaceutical  products  may  take  in  response  to  any  such  health  care  reform  proposals  or  legislation.  Adoption  of  price  controls  and  cost-
containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures reforms may prevent or limit our ability to generate
revenue, attain profitability or commercialize our product candidates.

Data Privacy and the Protection of Personal Information

We  are  subject  to  numerous  laws  and  regulations  governing  data  privacy  and  the  protection  of  personal  information  of  patients,  clinical  investigators,
employees,  and  vendors/business  contacts  including  in  relation  to  medical  records  and  other  health  information,  credit  card  data  and  financial  information.  The
legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues
which will continue to affect our business. In the United States, we may be subject to state security breach notification laws, state laws protecting the privacy of health
and personal information and federal and state consumer protections laws that regulate the collection, use, disclosure and transmission of personal information. These
laws overlap and often conflict and each of these laws is subject to varying interpretations by courts and government agencies, creating complex compliance issues. If
we  fail  to  comply  with  applicable  laws  and  regulations  we  could  be  subject  to  penalties  or  sanctions,  including  criminal  penalties  as  well  as  reputational  harm.  Our
customers  and  research  partners  must  comply  with  laws  governing  the  privacy  and  security  of  health  information,  including  HIPAA,  HITECH  and  state  health
information privacy laws. If we knowingly obtain protected health information without the authority to do so, our customers or research collaborators may be subject to
enforcement and we may have direct liability for the unlawful receipt of protected health information or for aiding and abetting a HIPAA violation.

Even  when  HIPAA  does  not  apply,  according  to  the  Federal  Trade  Commission,  or  the  FTC,  failing  to  take  appropriate  steps  to  keep  consumers’  personal
information secure, or failing to provide a level of security commensurate to promises made to individual about the security of their personal information (such as in a
privacy notice) may constitute unfair or deceptive acts or practices in violation of Section 5(a) of the Federal Trade Commission Act, or the FTC Act. The FTC expects a
company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its
business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered sensitive data that merits
stronger safeguards. The FTC’s guidance for appropriately securing consumers’ personal information is similar to what is required by the HIPAA Security Rule. The FTC
and states' Attorneys General have brought enforcement actions and prosecuted some data breach cases as unfair and/or deceptive acts or practices under the FTC
Act and comparable state laws.

State  laws  protecting  health  and  personal  information  are  becoming  increasingly  stringent.  For  example,  California  has  implemented  the  California
Confidentiality of Medical Information Act that imposes restrictive requirements regulating the use and disclosure of health information and other personally identifiable
information, and California has adopted the California Consumer Privacy Act of 2018, or CCPA, which went into effect in January of 2020. The CCPA mirrors a number
of the key provisions of the European General Data Protection Regulation, or GDPR, described below. The CCPA establishes a new privacy framework for covered
businesses by creating an expanded definition of personal information, establishing new data privacy rights for consumers in the State of California, imposing special
rules  on  the  collection  of  consumer  data  from  minors,  requiring  covered  companies  to  provide  new  disclosures  to  consumers  about  such  companies'  practices  for
collection and use of consumer data, and providing customers new ways to opt-out of certain sales or transfers of personal information. In addition, the CCPA creates a
new  and  potentially  severe  statutory  damages  framework  for  violations  of  the  CCPA  and  for  businesses  that  fail  to  implement  reasonable  security  procedures  and
practices  to  prevent  data  breaches.  While  there  is  currently  an  exception  for  protected  health  information  that  is  subject  to  HIPAA  and  clinical  trial  regulations,  as
currently  written,  the  CCPA  may  impact  our  business  activities.  More  recently,  a  new  privacy  law,  the  California  Privacy  Rights  Act,  or  CPRA,  was  approved  by
California voters in the election on November 3, 2020. The CPRA went into effect in January of 2023, modifying and strengthening the CCPA significantly, potentially
resulting  in  further  uncertainty,  additional  costs  and  expenses  in  an  effort  to  comply  and  additional  potential  for  harm  and  liability  for  failure  to  comply.  Among  other
things, the CPRA established a new regulatory authority, the California Privacy Protection Agency, which will be

45

enacting  new  regulations  and  will  have  expanded  enforcement  authority.  Various  states  such  as  Colorado,  Connecticut,  Delaware,  Florida,  Indiana,  Iowa,  Montana,
Oregon, Tennessee, Texas, Utah and Virginia have enacted their own privacy laws similar to the CCPA, and other states are considering proposals for such.

Health Care Reform and Potential Changes to Laws and Regulations

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes
regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect the ability
to profitably sell product candidates that receive marketing approval. FDA and other regulatory authority policies may change and additional government regulations
may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or
the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we otherwise may have
obtained and we may not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations.

Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in health care systems with the stated
goals of containing health care costs, improving quality and/or expanding access. Government authorities and other third-party payors have attempted to control costs
by limiting coverage and the amount of reimbursement for particular medical products and services, implementing reductions in Medicare and other health care funding
and applying new payment methodologies. In addition to the sweeping reforms contained in the ACA (summarized above in the section entitled “Coverage, Pricing, and
Reimbursement”), other legislative changes have been proposed and adopted in the United States that may affect health care expenditures. In addition to the IRA's
drug price negotiation provisions, discussed above, President Biden's Executive Order 14087, issued October 2022, called for CMS to prepare and submit a report to
the White House on potential payment and delivery modes that would complement to IRA, lower drug costs, and promote access to innovative drugs. In February 2023,
CMS published its report which described three potential models focusing on affordability, accessibility and feasibility of implementation for further testing by the CMS
Innovation Center. As of February 2024, the CMS Innovation Center continues to test the proposed models and has started to roll out plans for access model testing of
certain product types (e.g., cell and gene therapies) by states and manufacturers.

Other  new  laws  may  result  in  additional  reductions  in  Medicare  and  other  health  care  funding,  which  could  have  an  adverse  effect  on  customers  for  our
approved  product  and,  accordingly,  our  financial  operations.  We  cannot  predict  the  likelihood,  nature  or  extent  of  government  regulation  that  may  arise  from  future
legislation or administrative or executive action, either in the United States or abroad. We expect that additional state and federal health care reform measures will be
adopted in the future, any of which could limit the amounts that federal and state governments will pay for health care products and services. Moreover, if we are slow or
unable  to  adapt  to  changes  in  existing  requirements  or  the  adoption  of  new  requirements  or  policies,  or  if  we  are  not  able  to  maintain  regulatory  compliance,  our
therapeutic candidates may lose any marketing approval that may have been obtained and we may not achieve or sustain profitability, which would adversely affect our
business.

Government Regulation Outside the U.S.

In addition to regulations in the U.S., we may be subject to a variety of regulations in foreign jurisdictions that govern, among other things, clinical trials and any
commercial sales and distribution of our products, if approved, either directly or through our distribution partners. Whether or not we obtain FDA approval for a product
candidate, we must obtain the requisite approvals from regulatory authorities in foreign jurisdictions prior to the commencement of clinical trials or marketing and sale of
the  product  in  those  countries.  The  foreign  regulatory  approval  process  includes  all  of  the  risks  associated  with  the  FDA  approval  described  above,  and  the  time
required to obtain approval in other countries and jurisdictions might differ from and be longer than that required to obtain FDA approval. Some foreign jurisdictions have
a drug product approval process similar to that in the U.S., which requires the submission of a clinical trial application much like the IND prior to the commencement of
clinical  studies.  In  Europe,  for  example,  a  clinical  trial  application,  or  CTA,  must  be  submitted  to  each  country’s  national  health  authority  and  an  independent  ethics
committee, much like the FDA and IRB, respectively. Once the CTA is approved in accordance with a country’s requirements, clinical trial development may proceed. To
obtain  regulatory  approval  of  a  therapeutic  product  candidate  under  European  Union,  or  EU,  regulatory  systems,  we  would  be  required  to  submit  a  Marketing
Authorisation Application, which is similar to the NDA, except that, among other things, there are country-specific document requirements. For countries outside of the
EU, such as countries in Eastern Europe, Latin America or Asia, and recently the United Kingdom, the requirements governing the conduct of clinical trials, product
approval, pricing and reimbursement vary from country to country. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but
a failure or delay in obtaining regulatory approval in one country or jurisdiction may

46

negatively  impact  the  regulatory  process  in  others.  Moreover,  some  nations  may  not  accept  clinical  studies  performed  for  U.S.  approval  to  support  approval  in  their
countries or require that additional studies be performed on natives of their countries. In addition, in certain foreign markets, the pricing of drug products is subject to
government control and reimbursement may in some cases be unavailable or insufficient. We face the risk that the resulting prices would be insufficient to generate an
acceptable return to us or any future partner of ours. If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things,
fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions, and criminal prosecution.

International  marketing  and  distribution  of  medical  devices  are  also  subject  to  foreign  government  regulations,  which  may  vary  substantially  from  country  to
country.  There  is  a  trend  towards  harmonization  of  quality  system  standards  for  medical  device  products  among  the  European  Union,  United  States,  Canada  and
various other industrialized countries.

As of January 31, 2020, the United Kingdom is no longer a member state of the EU, and therefore a separate marketing authorization application and approval
will  be  required  to  market  a  medicinal  product  in  the  U.K.  The  Medicines  and  Healthcare  products  Regulatory  Agency  is  the  U.K.’s  standalone  pharmaceutical  and
medical devices regulator.

Review and Approval of Medicinal Products in the European Union

As  in  the  United  States,  medicinal  products  can  be  marketed  in  the  EU  only  if  a  marketing  authorization  from  the  competent  regulatory  agencies  has  been
obtained. Similar to the United States, the various phases of preclinical and clinical research in the EU are subject to significant regulatory controls. Also similar to the
United  States,  when  a  drug-device  combination  product’s  principal  intended  action  is  accomplished  by  the  drug  constituent  part,  the  EU  regulates  the  combination
product as a medicinal product.

Pursuant to the European Clinical Trials Directive, a system for the approval of clinical trials in the EU had been implemented through national legislation of the
member states. Under the previous system, an applicant obtained approval from the competent national authority of an EU member state in which the clinical trial was
conducted. Furthermore, the applicant could only start a clinical trial after a competent ethics committee had issued a favorable opinion. In April 2014, the new Clinical
Trials  Regulation,  (EU)  No  536/2014  (Clinical  Trials  Regulation)  was  adopted  and  became  effective  on  January  31,  2022.  The  Clinical  Trials  Regulation  is  directly
applicable in all the EU Member States, repealing the current Clinical Trials Directive 2001/20/EC. The extent to which ongoing clinical trials will be governed by the
Clinical Trials Regulation depends on when the Clinical Trials Regulation becomes applicable and on the duration of the individual clinical trial. If a clinical trial continues
for more than three years from the day on which the Clinical Trials Regulation becomes applicable the Clinical Trials Regulation will at that time begin to apply to the
clinical trial.

The new Clinical Trials Regulation aims to simplify and streamline the approval of clinical trials in the European Union. The main characteristics of the regulation
include: a streamlined application procedure via a single entry point, the “EU portal” called the Clinical Trial Information System, or CTIS; a single set of documents to
be prepared and submitted for the application as well as simplified reporting procedures for clinical trial sponsors; and a harmonized procedure for the assessment of
applications for clinical trials. Use of the CTIS became mandatory for new clinical trial application submissions as of February 1, 2023.

To  obtain  marketing  approval  of  a  drug  in  the  EU,  an  applicant  must  submit  a  marketing  authorization  application  (“MAA”)  either  under  a  centralized  or
decentralized  procedure.  The  centralized  procedure  provides  for  the  grant  of  a  single  marketing  authorization  by  the  European  Commission  that  is  valid  for  all  EU
member  states,  Iceland,  Lichtenstein  and  Norway.  The  centralized  procedure  is  compulsory  for  specific  products,  including  for  medicines  produced  by  certain
biotechnological  processes,  products  designated  as  orphan  medicinal  products,  advanced  therapy  products  (such  as  gene-therapy,  somatic  cell-therapy  or  tissue-
engineered medicines) and products with a new active substance indicated for the treatment of certain diseases. For products with a new active substance indicated for
the treatment of certain diseases and products that are highly innovative or for which a centralized process is in the interest of patients, the centralized procedure may
be optional. Under the centralized procedure the maximum timeframe for the evaluation of an MAA by the European Medicines Agency (“EMA”) is 210 days, excluding
clock stops, when additional written or oral information is to be provided by the applicant in response to questions asked by the Committee for Medicinal Products for
Human Use (“CHMP”). Accelerated assessment might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a major public
health interest, particularly from the point of view of therapeutic innovation. The timeframe for the evaluation of an MAA under the accelerated assessment procedure is
of 150 days, excluding stop-clocks.

47

The  decentralized  procedure  is  available  to  applicants  who  wish  to  market  a  product  in  specific  EU  member  states  where  such  product  has  not  received
marketing approval in any EU member states before. The decentralized procedure provides for an applicant to apply to one-member state to assess the application (the
reference member state) and specifically list other member states in which it wishes to obtain approval (concerned member states). Under this procedure, an applicant
submits an application based on identical dossiers and related materials, including a draft summary of product characteristics, and draft labelling and package leaflet, to
the reference member state and each concerned member state. The reference member state prepares a draft assessment report and drafts of the related materials
within 210 days after receipt of a valid application which is then reviewed and approved commented on by the concerned member states. Within 90 days of receiving
the  reference  member  state’s  assessment  report  and  related  materials,  each  concerned  member  state  must  decide  whether  to  approve  the  assessment  report  and
related materials.

In the EU, only products for which marketing authorizations have been granted may be promoted. A marketing authorization is valid for five years in principle
and the marketing authorization may be renewed after five years on the basis of a re-evaluation of the risk-benefit balance by the EMA or by the competent authority of
the authorizing member state. To this end, the marketing authorization holder must provide the EMA or the competent authority with a consolidated version of the file in
respect  of  quality,  safety  and  efficacy,  including  all  variations  introduced  since  the  marketing  authorization  was  granted,  at  least  six  months  before  the  marketing
authorization  ceases  to  be  valid.  Once  renewed,  the  marketing  authorization  is  valid  for  an  unlimited  period,  unless  the  European  Commission  or  the  competent
authority decides, on justified grounds relating to pharmacovigilance, to proceed with one additional five-year renewal. Any authorization which is not followed by the
actual placing of the drug on the EU market (in case of centralized procedure) or on the market of the authorizing member state within three years after authorization
ceases to be valid (the so-called sunset clause).

Moreover, even if authorized to be marketed in the EU, prescription-only medicines may only be promoted to health care professionals, not the general public.
All promotion should be in accordance with the particulars listed in the summary of product characteristics. Promotional materials must also comply with various laws,
and codes of conduct developed by pharmaceutical industry bodies in the EU which govern (among other things) the training of sales staff, promotional claims and their
justification,  comparative  advertising,  misleading  advertising,  endorsements,  and  (where  permitted)  advertising  to  the  general  public.  Failure  to  comply  with  these
requirements  could  lead  to  the  imposition  of  penalties  by  the  competent  authorities  of  the  EU  member  states.  The  penalties  could  include  warnings,  orders  to
discontinue the promotion of the drug product, seizure of promotional materials, fines and possible imprisonment.

Prior to May 26, 2021, the date on which the new Medical Device Regulation ("MDR") became effective, medical devices marketed in Europe were required to
comply with the Essential Requirements defined in Annex I to the EU Medical Devices Directive, or MDD, a coordinated system for the authorization of medical devices.
The MDD regulated the design, manufacture, clinical trials, labeling and adverse event reporting for medical devices. Devices that comply with the requirements of a
relevant  directive  are  entitled  to  bear  the  CE  conformity  marking,  indicating  that  the  device  conforms  to  the  essential  requirements  of  the  applicable  directives.  The
method of assessing conformity depended on the class of the product, but normally involved a combination of self-assessment by the manufacturer and a third-party
assessment by a “Notified Body.” This third-party assessment may consist of an audit of the manufacturer’s quality system and specific testing of the manufacturer’s
product.

In 2017, European Union regulatory bodies finalized a new Medical Device Regulation (“MDR”), which provided three years for transition and compliance, for a
final effective date of May 26, 2020. As a result of the COVID-19 pandemic, however, the implementation date was postponed by one year to May 26, 2021, and a
further transition period until May 26, 2024 gives the medical device industry and Notified Bodies additional time to come into compliance. The MDR changed several
aspects  of  the  existing  regulatory  framework  for  medical  device  marketing  in  Europe  and  increased  regulatory  oversight  of  all  medical  devices  marketed  in  the  EU,
which may, in turn, increase the costs, time and requirements that need to be met in order to place an innovative or high-risk medical device on the European market.
Specifically, the MDR requires post-market clinical follow-up evidence for medical devices, annual reporting of safety information for Class III products, and bi-annual
reporting for Class II products, unique device identification, or UDI, for all products, submission of core data elements to a European UDI database prior to placement of
a  device  on  the  market,  reclassification  of  medical  devices,  and  multiple  other  labeling  changes.  A  CE  certificate  issued  under  the  MDD  before  May  26,  2021  may
remain  valid  until  May  25,  2024  under  certain  conditions.  Longer  transition  periods  for  various  medical  devices  covered  by  certificates  or  declarations  of  conformity
issued  before  May  26,  2021  were  implemented  by  the  European  Commission  in  March  2023  in  order  to  mitigate  the  risk  of  device  shortages  in  the  EU.  The  new
transition periods permit devices certified in accordance with the MDD to remain on the market under such certifications until May 26, 2026 for class III implantable
custom-made devices, December

48

31, 2027 for Class III and implantable class IIb devices, and December 31, 2028 for all other class IIb and lower risk devices. As a new market entrant, however, the
transition provisions do not apply to our business and we must acquire approvals under the MDR for new products, which could be challenging and costly.

Review and Approval of Medicinal Products in Canada

Health Canada is the Canadian federal authority that regulates, evaluates and monitors the safety, effectiveness, and quality of drugs, medical devices, and
other  therapeutic  products  available  to  Canadians.  Health  Canada’s  regulatory  process  for  review,  approval  and  regulatory  oversight  of  products  is  similar  to  the
regulatory process conducted by the FDA. To initiate clinical testing of a drug candidate in human subjects in Canada, a CTA must be filed with and approved by Health
Canada.  In  addition,  all  federally  regulated  trials  must  be  approved  and  monitored  by  research  ethics  boards.  The  review  boards  study  and  approve  study-related
documents and monitor trial data.

Prior  to  being  given  market  authorization  for  a  drug  product,  a  manufacturer  must  present  substantive  scientific  evidence  of  a  product’s  safety,  efficacy  and
quality as required by the Food and Drugs Act (Canada) and its associated regulations, including the Food and Drug Regulations. This information is usually submitted
in the form of a New Drug Submission, or NDS. Health Canada reviews the submitted information, sometimes using external consultants and advisory committees, to
evaluate the potential benefits and risks of a drug. If after of the review, the conclusion is that the patient benefits outweigh the risks associated with the drug, the drug is
issued a Drug Identification Number (“DIN”), followed by a Notice of Compliance (“NOC"), which permits the market authorization holder (i.e., the NOC and DIN holder)
to market the drug in Canada. Drugs granted an NOC may be subject to additional postmarket surveillance and reporting requirements.

All establishments engaged in the fabrication, packaging/labeling, importation, distribution, and wholesale of drugs and operation of a testing laboratory relating
to  drugs  are  required  to  hold  a  Drug  Establishment  License  to  conduct  one  or  more  of  the  licensed  activities  unless  expressly  exempted  under  the  Food  and  Drug
Regulations. The basis for the issuance of a Drug Establishment License is to ensure the facility complies with cGMP as stipulated in the Food and Drug Regulations
and  as  determined  by  cGMP  inspection  conducted  by  Health  Canada.  An  importer  of  pharmaceutical  products  manufactured  at  foreign  sites  must  also  be  able  to
demonstrate that the foreign sites comply with cGMP, and such foreign sites are included on the importer’s Drug Establishment License.

Regulatory obligations and oversight continue following the initial market approval of a pharmaceutical product. For example, every market authorization holder
must report any new information received concerning adverse drug reactions, including timely reporting of serious adverse drug reactions that occur in Canada and any
serious  unexpected  adverse  drug  reactions  that  occur  outside  of  Canada.  The  market  authorization  holder  must  also  notify  Health  Canada  of  any  new  safety  and
efficacy issues that it becomes aware of after the launch of a product.

The  Canadian  regulatory  approval  requirements  for  new  drugs  outlined  above  are  similar  to  those  of  other  major  pharmaceutical  markets.  While  the  testing
carried out in Canada is often acceptable for the purposes of regulatory submissions in other countries, individual regulatory authorities may request supplementary
testing during their assessment of any submission. Therefore, the clinical testing conducted under Health Canada authorization or the approval of regulatory authorities
of other countries may not be accepted by regulatory authorities outside Canada or other countries.

Health Canada has also implemented a similar process as the FDA for regulating combination products comprising both drug and device constituent parts. The
agency considers the principal mechanism of action by which the claimed effect or purpose of the product is achieved, and then subjects the entire product to regulation
under either the Food and Drug Regulations or the Medical Devices Regulations.

Rest of the World Regulation

In addition to regulations in the United States, EU, and Canada, we may become subject to a variety of regulations governing clinical studies and commercial
sales and distribution of prescription drug and drug-device combination products in other jurisdictions around the world. These laws and regulations typically require the
licensing  of  manufacturing  and  contract  research  facilities,  carefully  controlled  research  and  testing  of  product  candidates  and  governmental  review  and  approval  of
results prior to marketing therapeutic product candidates. Additionally, they may require adherence to the FDA’s GLPs, GCPs, and cGMPs during manufacturing. The
process of new drug approvals

49

by regulators in the United States, Canada and the European Union are generally considered to be among the most rigorous in the world.

Whether or not FDA, EMA, or Health Canada approval is obtained for a product, we must obtain approval from the comparable regulatory authorities of other
countries before we can commence clinical studies or marketing of the product in those countries. The approval process varies from country to country and the time
may  be  longer  or  shorter  than  that  required  for  the  FDA,  EMA,  or  Health  Canada  approval.  The  requirements  governing  the  conduct  of  clinical  studies,  product
licensing, pricing and reimbursement vary greatly from country to country. In some international markets, additional clinical trials may be required prior to the filing or
approval of marketing applications within the country.

Moreover, outside of the United States, pricing and reimbursement schemes vary widely from country to country. Some countries provide that drug products
may  be  marketed  only  after  a  reimbursement  price  has  been  agreed  to.  Some  countries  may  require  the  completion  of  additional  studies  that  compare  the  cost-
effectiveness  of  a  particular  product  candidate  to  currently  available  therapies.  In  some  countries,  cross-border  imports  from  low-priced  markets  exert  competitive
pressure  that  may  reduce  pricing  within  a  country.  Any  country  that  has  price  controls  or  reimbursement  limitations  for  drug  products  may  not  allow  favorable
reimbursement and pricing arrangements.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension of clinical trials, suspension or

withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions, and criminal prosecution.

Europe – Data Privacy

On May 25, 2018, the GDPR went into effect, implementing a broad data protection framework that expanded the scope of EU data protection law, including to
non-EU  entities  that  process,  or  control  the  processing  of,  personal  data  relating  to  individuals  located  in  the  EU,  including  clinical  trial  data.  The  GDPR  sets  out  a
number of requirements that must be complied with when handling the personal data of European Union-based data subjects including: providing expanded disclosures
about how their personal data will be used; limitations on retention of personal data, higher standards for organizations to demonstrate that they have obtained valid
consent  or  have  another  legal  basis  in  place  to  justify  their  data  processing  activities;  requirements  to  conduct  data  protection  impact  assessments  for  "high  risk"
processing; the obligation to appoint data protection officers in certain circumstances; new rights for individuals to be “forgotten” and rights to data portability, as well as
enhanced current rights (e.g. access requests); the principal of accountability and demonstrating compliance through policies, procedures, training and audit; and a new
mandatory data breach regime. In particular, medical or health data, genetic data and biometric data where the latter is used to uniquely identify an individual are all
classified as “special category” data under the GDPR and afforded greater protection and require additional compliance obligations. Further, EU member states have a
broad right to impose additional conditions – including restrictions – on these data categories. This is because the GDPR allows EU member states to derogate from the
requirements of the GDPR mainly in regard to specific processing situations (including special category data and processing for scientific or statistical purposes). As the
EU member states continue to reframe their national legislation to harmonize with the GDPR, we will need to monitor compliance with all relevant EU member states’
laws and regulations, including where permitted derogations from the GDPR are introduced.

We will also be subject to evolving EU laws on data export, if we transfer data outside the EU to ourselves or third parties outside of the EU. The GDPR only
permits exports of data outside the EU to countries deemed by the European Commission to have adequate data privacy laws or where there is a suitable data transfer
solution in place to safeguard personal data (e.g. the European Union Commission approved Standard Contractual Clauses). On July 16, 2020, the Court of Justice of
the European Union or the CJEU, issued a landmark opinion in the case Maximilian Schrems vs. Facebook (Case C-311/18), called Schrems II. This decision a) calls
into  question  certain  data  transfer  mechanisms  as  between  the  EU  member  states  and  the  U.S.  and  b)  invalidates  the  EU-U.S.  Privacy  Shield  on  which  many
companies had relied as an acceptable mechanism for transferring such data from the EU to the U.S.

On July 10, 2023, the European Commission adopted an adequacy decision for a new mechanism for transferring data from the EU to the United States – the
EU-US Data Privacy Framework, which provides EU individuals with several new rights, including the right to obtain access to their data, or obtain correction or deletion
of  incorrect  or  unlawfully  handled  data.  The  adequacy  decision  followed  the  signing  of  an  executive  order  introducing  new  binding  safeguards  to  address  the  points
raised  in  the  Schrems II  decision.  Notably,  the  new  obligations  were  geared  to  ensure  that  data  can  be  accessed  by  U.S.  intelligence  agencies  only  to  the  extent
necessary and proportionate and to establish an independent and impartial redress mechanism to handle complaints from Europeans concerning the collection of their
data for national security purposes. The European Commission will continually review developments in the U.S. along with its adequacy decision. Adequacy decisions
can be adapted or even

50

withdrawn  in  the  event  of  developments  affecting  the  level  of  protection  in  the  applicable  jurisdiction.  Future  actions  of  EU  data  protection  authorities  are  difficult  to
predict. Some customers or other service providers may respond to these evolving laws and regulations by asking us to make certain privacy or data-related contractual
commitments that we are unable or unwilling to make. This could lead to the loss of current or prospective customers or other business relationships.

If we have to rely on third parties to carry out services for us, including processing personal data on our behalf, we are required under the GDPR to enter into
contractual arrangements to help ensure that these third parties only process such data according to our instructions and have sufficient security measures in place.
Any security breach or non-compliance with our contractual terms or breach of applicable law by such third parties could result in enforcement actions, litigation, fines
and penalties or adverse publicity and could cause customers to lose trust in us, which would have an adverse impact on our reputation and business. Any contractual
arrangements requiring the transfer of personal data from the EU to us in the United States will require greater scrutiny and assessments as required under Schrems II
and may have an adverse impact on cross-border transfers of personal data, or increase costs of compliance.

The GDPR provides an enforcement authority to impose large penalties for noncompliance, including the potential for fines of up to €20 million or 4% of the
annual  global  revenues  of  the  noncompliant  company,  whichever  is  greater.  We  will  be  subject  to  the  GDPR  when  we  have  a  European  Union  presence  or
“establishment” (e.g., EU based subsidiary or operations), when conducting clinical trials with EU based data subjects, whether the trials are conducted directly by us or
through a vendor or partner, or offering approved products or services to EU-based data subjects, regardless of whether involving a EU based subsidiary or operations.

U.S. Foreign Corrupt Practices Act

The  U.S.  Foreign  Corrupt  Practices  Act,  or  FCPA,  prohibits  U.S.  corporations  and  their  representatives  from  offering,  promising,  authorizing  or  making
payments to any foreign government official, government staff member, political party or political candidate in an attempt to obtain or retain business abroad. The scope
of the FCPA would include interactions with certain health care professionals in many countries, either directly or through third parties. Our present and future business
has been and will continue to be subject to various other U.S. and foreign laws, rules and/or regulations.

Environmental, Health and Safety Regulation

We  are  subject  to  numerous  federal,  state  and  local  environmental,  health  and  safety,  or  EHS,  laws  and  regulations  relating  to,  among  other  matters,  safe
working conditions, product stewardship, environmental protection, and handling or disposition of products, including those governing the generation, storage, handling,
use, transportation, release, and disposal of hazardous or potentially hazardous materials, medical waste, and infectious materials that may be handled by our research
laboratories. Some of these laws and regulations also require us to obtain licenses or permits to conduct our operations. If we fail to comply with such laws or obtain
and  comply  with  the  applicable  permits,  we  could  face  substantial  fines  or  possible  revocation  of  our  permits  or  limitations  on  our  ability  to  conduct  our  operations.
Certain of our development and manufacturing activities involve use of hazardous materials, and we believe we are in compliance with the applicable environmental
laws, regulations, permits, and licenses. However, we cannot ensure that EHS liabilities will not develop in the future. EHS laws and regulations are complex, change
frequently and have tended to become more stringent over time. Although the costs to comply with applicable laws and regulations, have not been material, we cannot
predict  the  impact  on  our  business  of  new  or  amended  laws  or  regulations  or  any  changes  in  the  way  existing  and  future  laws  and  regulations  are  interpreted  or
enforced, nor can we ensure we will be able to obtain or maintain any required licenses or permits.

Employees

As of March 27, 2024, we had 26 employees. Twenty three of our employees are full-time and three are part-time, 18 are in research and development and
eight are in general and administrative. Given the differing characteristics of our product candidates, our approach is to engage consultants with experience in varying
specialties to help us develop such candidates. Our numerous consultants serve as an extension to our employee base. We believe this approach enables us to access
the expertise needed in a cost-efficient manner and without the need to rapidly increase the number of full-time employees and their associated costs. In the future, if
we select a commercialization strategy for a product candidate that requires us to establish marketing, sales or distribution infrastructure and capabilities, we may need
to rapidly increase our employee base.

ITEM 1A. RISK FACTORS

Summary of Risk Factors

Below is a summary of the principal factors that make an investment in our securities speculative or risky. This summary does not address all of the risks that
we face. We urge investors to carefully review and consider the additional discussion of the risks summarized in this risk factor summary, and other risks that we face,
which can be found below under the heading “Risk Factors,” together with other information in this report, before making investment decisions regarding our securities.

• We will need to raise substantial additional capital to continue our operations, execute our business strategy and remain a going concern, and we may not
be  able  to  raise  adequate  capital  on  a  timely  basis,  on  favorable  terms,  or  at  all.  Raising  additional  capital  may  cause  substantial  dilution  to  our
stockholders, restrict our operations or require us to relinquish rights in our technologies or product candidates and their future revenue streams.

• We have a limited operating history, have incurred significant losses since our inception and expect to continue to incur losses for the foreseeable future,

which, together with our limited financial resources and substantial capital requirements, make it difficult to assess our prospects.

• Our business depends on obtaining the approval of regulatory authorities, and in particular, FDA approval, to market products that we develop. All of our
product  candidates  are  investigational,  require  the  conduct  and  successful  completion  of  clinical  studies  and  nonclinical  work,  and  may  never  complete
development or be submitted for or receive regulatory approval. The FDA's approval of XACIATO is not predictive of favorable development or marketing
approval outcomes for our product candidates.

• Clinical  development  is  a  lengthy  and  expensive  process  with  an  inherently  uncertain  outcome.  Failure  to  successfully  complete  clinical  trials  and
nonclinical activities and obtain regulatory approval to market and sell our product candidates on our anticipated timelines at reasonable costs to us, or at
all, particularly Ovaprene and Sildenafil Cream, could have a material adverse effect on our business, operating results and financial condition.

•

The regulatory approval processes of the FDA and comparable foreign authorities are expensive, lengthy, time-consuming, and inherently unpredictable. If
we are not able to obtain regulatory approvals for our product candidates, our ability to generate product revenue will be materially impaired.

• Drug  products  and  drug/device  combination  products  are  complex  to  manufacture  and  we  face  significant  challenges  in  scaling  up  manufacturing  of  our
product candidates for larger clinical trials and commercial production. Manufacturing and supply delays and disruptions could postpone the initiation of or
interrupt our clinical studies, extend the timeframe and cost of development of our product candidates, delay potential regulatory approvals and adversely
impact the commercialization of any approved products.

•

Strategic collaborations are a key part of our strategy and our existing strategic collaborations are important to our business. If we are unable to maintain
existing  strategic  collaborations  or  establish  new  ones,  or  if  they  are  not  successful,  we  may  require  substantial  additional  capital  to  develop  and
commercialize our products and product candidates and our business and prospects may be materially harmed.

• Unless and until one of our product candidates receives regulatory approval, payments under our license agreement with Organon based on net sales of

XACIATO represent our only potential source of ongoing revenue and the amount of those net sales is largely outside of our control.

• We have no manufacturing, sales, marketing or distribution infrastructure. We depend heavily on, and expect to continue to rely on, the performance of third
parties, including our strategic collaborators, contract manufacturers and suppliers, CROs, medical institutions, and scientific, medical, regulatory and other
consultants  and  advisors,  to  develop  our  product  candidates  and  commercialize  any  approved  products.  Failure  of  these  third  parties  to  perform  as
expected could result in substantial delays, increased costs or failures of our product development programs, delayed or unsuccessful commercialization of
any approved products, and the need for significant additional capital.

• Due  in  part  to  our  limited  financial  and  human  resources,  we  may  fail  to  effectively  execute  our  product  development,  regulatory  submission  and

commercialization plans in accordance with communicated timelines, or at all.

53

•

•

•

•

The  loss  or  impairment  of  our  rights  under  our  license  agreements  for  XACIATO  or  any  of  our  product  candidates  could  prevent  us  from  developing  or
commercializing them, which could have a material adverse effect on our business prospects, operations and viability.

The commercial success of XACIATO will depend on Organon’s efforts and capabilities and a variety of factors, many of which currently are unknown or
uncertain, and if commercialization of XACIATO is not successful, our reputation, business and prospects may suffer.

XACIATO and any future products will face intense competition, including from generic products, and may fail to achieve the degree of market acceptance
necessary for commercial success. Our business, operating results and financial condition will suffer if we, or our commercial collaborators, fail to compete
effectively and fail to achieve market acceptance.

Failure  to  successfully  obtain  coverage  and  adequate  reimbursement  for  XACIATO  and  any  future  products  from  government  health  care  programs  and
other third-party payors would diminish our ability, or that of a commercial collaborator, to generate net product revenue or net sales. If out-of-pocket costs
for products we develop are deemed by women to be unaffordable, a commercial market may never develop.

• We have a relatively small number of employees, and if we fail to attract and retain key personnel or effectively manage our personnel costs, our business

may materially suffer.

• We  may  not  be  successful  in  our  efforts  to  identify  and  acquire  or  in-license  additional  product  candidates  or  technologies,  which  may  limit  our  growth

potential.

• Our failure to adequately protect or enforce our intellectual property rights, and those of our licensors, could materially harm our proprietary position in the

marketplace or prevent or impede the commercialization of XACIATO and any future products.

•

•

•

•

•

•

Lack  of  patent  protection  for  the  active  ingredients  in  certain  of  our  product  candidates,  including  Sildenafil  Cream  and  DARE-HRT1,  may  limit  the
commercial opportunity for those products if competitors are able to develop and commercialize safe and effective alternative formulations or methods of
delivery of the active ingredients.

Volatility in the financial markets, geopolitical conflicts and events, public health emergencies such as the COVID-19 pandemic and other macroeconomic
factors may negatively impact our business, financial condition and results and our stock price, including by increasing the cost and timelines for our clinical
development programs or making it more difficult or costly to raise additional capital when needed.

Product liability lawsuits against us could cause us to incur substantial liabilities and divert management attention from our business.

The price of our common stock has been and may continue to be highly volatile and such volatility may be related or unrelated to our performance and
operating  results.  Volatility  in  our  stock  price  may  subject  us  to  increased  risk  of  securities  litigation,  including  class-action  lawsuits,  which  could  be
expensive and divert management attention.

If  we  fail  to  regain  and  maintain  compliance  with  the  continued  listing  requirements  of  the  Nasdaq  Capital  Market,  our  common  stock  could  be  delisted,
which could, among other things, limit demand for our common stock, substantially impair our ability to raise additional capital and have an adverse effect
on the market price of, and the efficiency of the trading market for, our common stock.

Future dilution to our existing stockholders from sales and issuances of our common stock through at-the-market, or ATM, offerings, other types of public or
private offerings of equity or equity-linked securities and upon the exercise of stock options, or the market's expectation that such sales could adversely
affect our stock price, even if our business is doing well.

• We have been subject to a cyber-related crime and our controls and security measures may not be successful in preventing other cybersecurity incidents in
the future. Cyber-attacks, security breaches, loss of data and other disruptions to our information technology systems or those of our strategic collaborators
or  third-party  service  providers  could  compromise  sensitive  information  related  to  our  business,  delay  or  prevent  us  from  accessing  critical  information,
subject us to significant financial loss, or expose us to liability, any of which could adversely affect our business and our reputation.

Risk Factors

Investment in our securities involves a high degree of risk and uncertainty. Our business, operating results, growth prospects and financial condition are subject

to various risks, many of which are not exclusively within our

54

control,  that  may  cause  actual  performance  to  differ  materially  from  historical  or  projected  future  performance.  We  urge  investors  to  consider  carefully  the  risks
described  below,  together  with  all  of  the  information  in  this  report  and  our  other  public  filings,  before  making  investment  decisions  regarding  our  securities.  Each  of
these risk factors, as well as additional risks not presently known to us or that we currently deem immaterial, could adversely affect our business, operating results,
growth prospects or financial condition, as well as the trading price of our common stock, in which case you may lose all or part of your investment.

Risks Related to Our Financial Position and Capital Needs

We will need to raise substantial additional capital to continue our operations and execute our business strategy, and we may not be able to raise adequate
capital on a timely basis, on favorable terms, or at all.

We have a history of losses from operations, we expect negative cash flows from our operations to continue for the foreseeable future, and we expect that our
net losses will continue for the foreseeable future as we develop and seek to bring to market our existing product candidates and as we seek to potentially acquire or
license  and  develop  additional  product  candidates.  These  circumstances  raise  substantial  doubt  about  our  ability  to  continue  as  a  going  concern.  Our  financial
statements  as  of  December  31,  2023  were  prepared  under  the  assumption  that  we  will  continue  as  a  going  concern  and  do  not  include  any  adjustments  that  might
result  from  the  outcome  of  this  uncertainty.  At  December  31,  2023,  our  accumulated  deficit  was  approximately  $171.2  million,  our  cash  and  cash  equivalents  were
approximately $10.5 million, our deferred grant funding liability under our grant agreements related to DARE-LARC1 and DARE-LBT was approximately $13.7 million,
and  our  working  capital  deficit  was  approximately  $2.9  million.  Our  cash  and  cash  equivalents  at  December  31,  2023  represented  funds  received  under  such  grant
agreements and such funds may be applied solely toward direct costs for the development of DARE-LARC1 and DARE-LBT, other than approximately 10% of such
funds,  which  may  be  applied  toward  general  overhead  and  administration  expenses  that  support  our  entire  operations.  We  will  require  additional  capital  to  fund  our
operating needs into the third quarter of 2024. and to meet our current obligations as they become due. Advancing our investigational women's health products through
clinical development and pursuing regulatory approval and commercialization will require substantial additional investment. We will need to raise substantial additional
capital  to  continue  to  fund  our  operations  and  execute  our  current  business  strategy.  The  amount  and  timing  of  our  capital  needs  have  and  will  continue  to  depend
highly on many factors, as discussed further below as well as under "ITEM 7. MANAGEMENT'S DISCUSSION OF AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS—Liquidity and Capital Resources—Plan of Operations and Future Funding Requirements."

Our management may devote significant time and we may incur substantial costs in pursuing, evaluating and negotiating potential capital-raising transactions
and those efforts may not prove successful on a timely basis, or at all. If we cannot raise adequate additional capital when needed, we may be forced to reduce, or even
terminate our operations. We may delay, scale back or eliminate one or more of our product development programs; relinquish rights under our license agreements with
third parties relating to our product candidates; forgo opportunities to expand our product portfolio; take other measures to reduce our expenses; reorganize or merge
with another entity; or file for bankruptcy or cease operations. If we become unable to continue as a going concern, we may have to liquidate our assets, and might
realize  significantly  less  than  the  values  at  which  they  are  carried  on  our  financial  statements,  and  our  stockholders  may  lose  all  or  part  of  their  investment  in  our
common stock.

Our capital needs have depended on, and will continue to depend on, many factors that are highly variable and difficult to predict, including:

•
•
•
•
•

•

•

the product development programs we choose to pursue;

the cost and pace of preclinical and clinical development;

the results of preclinical activities and clinical trials;

the cost and timing of obtaining clinical supplies of product candidates;

the cost and timing of regulatory submissions and decisions by the FDA and other regulatory authorities on our applications to commence and advance
clinical development of and to market our product candidates;

the amount and timing of payments to third parties required under acquisition, in-license and other agreements relating our rights to develop and
commercialize our product and product candidates;

the cost and timing of commercialization activities we undertake or engage third parties to undertake for any approved product;

55

•

•

•
•

the amount and timing of future royalty, milestone or other payments, if any, we receive under our commercial collaboration agreements for XACIATO and
Ovaprene;

our ability to maintain, and establish new, strategic collaborations relating to the development and/or commercialization of our product and product
candidates;

the extent to which we acquire, in-license, or otherwise invest in new product candidates or technologies and the terms of any such transaction; and

the cost and timing of preparing, filing, and prosecuting patent applications, maintaining and enforcing our intellectual property rights, and defending any
intellectual property-related claims, including any claims by third parties that we are infringing upon their intellectual property rights.

Should we add product candidates to our portfolio, should our existing product candidates require testing or other capital-intensive development activities that
we do not anticipate, should the duration of our clinical trials be longer than anticipated, should manufacturing and supply be disrupted, or should regulatory approvals
be delayed, our cash resources will be further strained. Should our product development efforts succeed, we will need to develop a commercialization plan for each
product,  which  may  also  require  significant  resources  to  create  and  implement.  In  addition,  the  terms  of  any  collaboration  agreements  for  development  and/or
commercialization of our product and product candidates may significantly impact our need for additional capital. Because of these uncertainties and the other risks and
uncertainties discussed in this “Risk Factors” section, we cannot reasonably estimate the amount funding necessary to successfully complete development of and seek
regulatory  approval  for  our  product  candidates  or  to  commercialize  any  approved  products.  In  addition,  we  may  seek  additional  capital  due  to  favorable  market
conditions or strategic considerations even if we believe we have sufficient funds for our planned operations.

We  may  seek  to  raise  additional  capital  through  a  variety  of  means,  including  equity,  equity-linked  or  debt  securities  offerings,  government  or  other  grant
funding,  strategic  collaborations  or  alliances,  debt,  royalty  monetization  or  other  structured  financings,  or  other  similar  types  of  arrangements.  Our  past  success  in
raising capital through equity offerings, grant funding, collaboration agreements, and a royalty monetization financing should not be viewed as an indication we will be
successful in raising capital through those or any other means in the future. We expect that our ability to raise additional capital and the amount of capital available to us
will depend not only on progress we and our collaborators make toward successfully developing, obtaining regulatory approval for and commercializing our product and
product candidates, but also on factors outside of our control, such as macroeconomic and financial market conditions. To the extent we seek to obtain additional capital
before  achieving  clinical,  regulatory  and/or  sales  milestones  or  when  our  stock  price  or  trading  volume  or  both  are  low,  or  when  the  general  market  for
biopharmaceutical or women’s health companies is weak, additional capital may not be available to us on favorable terms, or at all.

Unstable  and  unfavorable  market  and  economic  conditions  may  harm  our  ability  to  raise  additional  capital.  The  occurrence  or  continued  occurrence  of
macroeconomic factors or events similar to those experienced in recent years, such as a U.S. economic crisis or recession or recessionary concerns, inflation, public
health emergencies (such as the COVID-19 pandemic), geopolitical conflict (such as the wars in Ukraine and the Middle East), natural/environmental disasters, supply-
chain disruptions, terrorist attacks, strained relations between the U.S. and a number of other countries, social and political discord and unrest in the U.S. and other
countries, and government shutdowns, among others, increase market volatility and have long-term adverse effects on the U.S. and global economies and financial
markets. Volatility and deterioration in the financial markets and liquidity constraints or other adverse developments affecting financial institutions may make equity or
debt financings more difficult, more costly or more dilutive and may increase competition for, or limit the availability of, funding from other third-party sources, such as
from strategic collaborations and government and other grants.

Raising additional capital may cause substantial dilution to our stockholders, restrict our operations or require us to relinquish rights in our technologies or
product candidates and their future revenue streams.

As discussed above, we may seek to raise additional capital through a variety of means. Raising capital through the issuance of shares of our common stock,
or securities convertible into or exercisable for our common stock, may depress our stock price and substantially dilute our existing stockholders. The terms of securities
issued may include liquidation or other preferences that may materially adversely affect the rights of our existing stockholders. Debt and other structured financings, if
available, would increase our fixed payment obligations and may involve covenants requiring us to maintain specified financial ratios or a specified cash balance, or
limiting or restricting our ability to take specific actions, such as incurring additional debt, acquiring, selling or licensing intellectual property rights, and making capital
expenditures, or impose other operating restrictions that could adversely impact our ability to operate our business and pursue our strategic objectives. We could also
be required to

56

meet certain milestones in connection with a debt financing and the failure to achieve such milestones by certain dates may force us to relinquish rights to some of our
technologies,  product  candidates  or  products,  or  otherwise  agree  to  terms  unfavorable  to  us.  In  addition,  we  may  be  required  to  relinquish  valuable  rights  to  future
revenue streams, such as in the case of the royalty interest financing agreement we entered into in December 2023. Moreover, the lower our cash balance when we
seek to raise additional capital, the more difficult, costly or dilutive to our existing stockholders it may be for us to raise additional capital.

We  may  be  required  to  seek  additional  capital  through  arrangements  with  collaborators  at  an  earlier  stage  of  development  or  commercialization  of  our
technologies, product candidates or products than otherwise would be desirable, in which case we may grant rights to our technologies, product candidates or products
on terms that may not be as favorable to us or grant rights that we would otherwise prefer to retain. If we raise capital through new collaborations, strategic alliances or
other similar types of arrangements, we may relinquish valuable rights to future revenue streams. Licensing agreements likely would significantly reduce our control
over the development or commercialization of the licensed technology, product candidates or products, and our collaborators may become unable or unwilling to devote
adequate resources to realize their full potential value. If we obtain funding through grants from governmental entities or private organizations, such parties may impose
restrictions on our rights to technologies, product candidates or products developed with such funding, obtain rights to license such technologies, product candidates or
products to third parties (e.g., if we are unable or unwilling to commercialize a product or make it available to certain patient populations in a timely manner or at certain
prices), or require future royalty or other payments if such technologies, product candidates or products are commercialized.

We have a limited operating history, have incurred significant losses since our inception and expect to continue to incur losses for the foreseeable future,
which, together with our limited financial resources and substantial capital requirements, make it difficult to assess our prospects.

We have a limited operating history upon which to evaluate our business and prospects. The development of drug and drug/device combination products in
order  to  obtain  regulatory  approval  is  a  highly  speculative,  lengthy  and  expensive  undertaking  and  involves  substantial  risk.  We  cannot  accurately  determine  the
duration and completion costs of our development programs, or if, when and to what extent we will generate revenue from the commercialization of any of our product
candidates. Other than XACIATO, which was recently commercially launched by our collaborator Organon, we have not obtained any regulatory approvals for any of our
product candidates, commercialized any of our product candidates or generated any product revenue. We do not expect the potential milestone and royalty payments to
us under our exclusive license agreement for XACIATO will be sufficient to cover our operating expenses. We have not been profitable since we commenced operations
and  may  never  achieve  profitability.  We  devote  significant  resources  to  licensing  or  otherwise  acquiring  the  rights  to  our  product  candidates  and  to  research  and
development, or R&D, activities for them. Since inception, we have incurred significant operating losses. As discussed above, we must raise additional capital to finance
our operations and remain a going concern and adequate additional capital may not be available to us on a timely basis, or at all.

If one of our commercial collaborators terminates its exclusive license agreement with us, our need for additional capital may significantly increase.

We have entered into an exclusive license agreement with Organon for the commercialization of XACIATO and an exclusive license agreement with Bayer for
the  commercialization  of  Ovaprene,  if  approved.  Each  of  these  license  agreements  may  be  terminated  by  the  licensee  for  convenience  upon  the  completion  of  a
specified notice period, subject to limited restrictions. Furthermore, under our agreement with Bayer, Bayer has no payment obligations to us, unless, after reviewing the
results of our pivotal clinical trial of Ovaprene, it elects, in its sole discretion, to make the license grant under our agreement effective by making a $20.0 million payment
to us. If we do not successfully complete a pivotal clinical trial of Ovaprene in a timely manner, the license grant may never become effective, and we may not receive
any additional payments from Bayer. Bayer may elect not to make the license grant effective regardless of the outcome of the pivotal clinical trial. If an exclusive license
agreement is terminated early, or in Ovaprene's case, does not become fully effective, we may realize only a small fraction of the potential value of the agreement to us,
and we would need to raise significant additional capital to pursue further development and commercialization of XACIATO or Ovaprene, as applicable, or establish
another commercial collaboration, which we may not be able to do on a timely basis, on favorable terms, or at all.

The royalties we may receive under our license agreements with our commercial collaborators are based on net sales, which will be largely outside of our
control.

We  expect  XACIATO’s  and  Ovaprene’s  value  to  us  under  our  license  agreements  with  Organon  and  Bayer,  assuming  the  license  grant  to  Bayer  becomes
effective,  to  be  generated  primarily  through  royalties  and  potential  commercial  milestone  payments,  in  each  case,  based  on  net  sales.  The  amount  of  net  sales  our
products may

57

generate, if any, is largely outside of our control because marketing and sales activities will be conducted by the licensee and the product pricing will be determined by
the  licensee.  Gross  sales  can  be  greatly  reduced  by  sales  discounts  and  allowances,  which  will  also  be  determined  by  the  licensee  (or  mandated  by  governmental
entities) and outside of our control. Sales discounts may be particularly substantial for new products compared to established products to incentivize purchases and
promote customer loyalty. These factors would serve to reduce our royalties and delay potential achievement of commercial milestones. If a commercial collaborator
has  no  or  limited  commercialization  success,  or  net  sales  are  otherwise  minimal  due  to  pricing  and  discount  structures,  our  operating  results  would  be  negatively
impacted and our need for additional capital could significantly increase or be accelerated.

In  the  future,  we  may  rely  on  revenues  received  from  third-party  licensees  to  fund  our  operations,  and  failure  to  receive  such  revenues,  or  receipt  of  only

minimal revenue, may cause us to, among other things:

•

•
•
•
•
•

pursue raising additional funds through equity or debt financings that could be dilutive to our stockholders or involve restrictive covenants, operational
restrictions and security interests in our assets;

enter into new strategic collaborations that may be less favorable than those we would have obtained under different circumstances;

delay, reduce or terminate one or more development programs;

reduce headcount;

forgo opportunities to expand our product portfolio; or

take other measures to reduce our expenses, pursue strategic transactions, such as a merger or other business combination or sale of assets, file for
bankruptcy, or cease operations.

We have relied heavily on sales of our common stock to fund our operations, and our future ability to obtain additional capital through stock sales or other
securities offerings may be more costly or dilutive to our stockholders than in the past, or may not be available to us at all. Our ability to raise additional
capital may be limited by a low trading volume, stock price and market capitalization, as well as by laws, regulations and market conditions.

We have relied heavily on our ability to raise capital by selling shares of our common stock. For example, we raised an aggregate of approximately $79.1 million
in gross proceeds in fiscal years 2021 and 2022 through the sale of shares of our common stock in offerings made under a Form S-3 “shelf” registration statement. Our
ability to raise additional capital through sales of our common stock or other securities offerings will depend on several factors, many of which may not be in our favor,
including the trading volume and volatile trading price of our common stock, our relatively low public float and market capitalization, our potential inability to regain and
maintain compliance with the listing requirements of the Nasdaq Capital Market, unfavorable financial market conditions, and the other risks and uncertainties described
in this “Risk Factors” section. If we are unable to raise additional capital through the offering and sale of shares of our common stock, or securities convertible into or
exercisable for our common stock, on a timely basis or acceptable terms, or at all, we may seek additional capital through other third-party sources that require us to
relinquish valuable rights in our intellectual property, technologies, product candidates or future revenue streams, or that subject us to restrictive covenants, operational
restrictions or security interests in our assets, or we may need to delay, scale back or eliminate some or all of our development programs, reduce other expenses, file
for bankruptcy, reorganize, merge with another entity, or cease operations.

Using a shelf registration statement to conduct an equity offering to raise capital generally takes less time and is less expensive than other means, such as
conducting an offering under a Form S-1 registration statement. We currently have a shelf registration statement effective, however, our ability to raise capital under a
shelf registration statement is, and may continue to be, limited by, among other things, current and future SEC rules and regulations impacting the eligibility of smaller
companies  to  use  Form  S-3  for  primary  offerings  of  securities.  For  example,  we  currently  are  subject  to  the  "baby  shelf  rule"  because  the  market  value  of  our
outstanding  shares  of  common  stock  held  by  non-affiliates,  or  our  public  float,  was  less  than  $75.0  million  at  the  time  of  filing  this  annual  report  on  Form  10-K,
calculated in accordance with SEC rules. This means that we may use our shelf registration statement to raise additional funds only to the extent that the aggregate
market value of securities sold by us or on our behalf pursuant to Instruction I.B.6. of Form S-3 during the 12 calendar months immediately prior to, and including, the
intended sale does not exceed one-third of the aggregate market value of our public float, calculated in accordance with the instructions to Form S-3. As an example, as
of  March  27,  2024,  we  could  not  offer  or  sell  more  than  approximately  $19.0  million  of  new  securities  under  our  shelf  registration  statement.  If  our  ability  to  offer
securities under an effective shelf registration statement is limited, including by the baby shelf rule, we may choose to conduct an offering of our securities under an
exemption from registration under the Securities Act or under a Form S-1 registration statement.

58

We  would  expect  either  of  these  alternatives  to  take  more  time  and  be  a  more  expensive  method  of  raising  additional  capital  relative  to  using  our  shelf  registration
statement.

In addition, under SEC rules and regulations, our common stock must be listed and registered on a national securities exchange in order to use a Form S-3
registration statement (1) for a primary offering, if our public float is not at least $75.0 million as of a date within 60 days prior to the date of filing the Form S-3 or a re-
evaluation date, whichever is later, and (2) to register the resale of our securities by persons other than us (i.e., a resale offering). While our common stock is currently
listed  on  the  Nasdaq  Capital  Market,  there  can  be  no  assurance  that  we  can  maintain  such  listing.  See,  “Risks  Related  to  Our  Securities—If  we  fail  to  regain  and
maintain compliance with the continued listing requirements of the Nasdaq Capital Market, our common stock could be suspended and delisted, which could, among
other things, limit demand for our common stock, substantially impair our ability to raise additional capital and have an adverse effect on the market price of, and the
efficiency of the trading market for, our common stock,” below.

Our  ability  to  raise  capital  on  a  timely  basis  through  the  issuance  and  sale  of  equity  securities  may  also  be  limited  by  Nasdaq’s  stockholder  approval
requirement for any transaction that is not a public offering (as defined in Nasdaq listing rules). For transactions other than public offerings, Nasdaq requires stockholder
approval prior to the issuance or potential issuance of common stock (or securities convertible into or exercisable for common stock) at a price per share that is less
than the "Minimum Price" if the issuance (together with sales by our officers, directors and substantial shareholders (as defined in Nasdaq listing rules)) would equal
20% or more of our common stock outstanding before the issuance. Under Nasdaq rules, the "Minimum Price" means a price that is the lower of (i) the Nasdaq official
closing price immediately preceding the signing of the binding agreement; or (ii) the average Nasdaq official closing price of the common stock for the five trading days
immediately preceding the signing of the binding agreement. In addition, certain prior sales of securities by us may be aggregated with any offering we may propose at
a price that is less than the Minimum Price and which is not considered a public offering by Nasdaq, further limiting the amount we could raise in the offering. Under
Nasdaq rules, stockholder approval is also required prior to the issuance of securities when the issuance or potential issuance will result in a change of control of our
company. Even if a public offering under Nasdaq rules is not subject to the 20% limitation described above, it may involve publicly announcing the proposed transaction
before it is completed, which often has the effect of depressing a company's stock price. Accordingly, our existing investors may suffer greater dilution if we seek to
raise additional capital through such a public offering of our securities.

Obtaining stockholder approval is a costly and time-consuming process. If we must obtain stockholder approval for a potential transaction, we would expect to
spend  substantial  additional  money  and  resources.  In  addition,  seeking  stockholder  approval  would  delay  our  receipt  of  otherwise  available  capital,  which  may
materially and adversely affect our ability to execute our business plan, and there is no guarantee our stockholders ultimately would approve a proposed transaction.

Due in part to our limited financial resources, we may fail to select or capitalize on the most scientifically, clinically or commercially promising or profitable
indications  or  therapeutic  areas  for  our  product  candidates,  we  may  be  unable  to  pursue  and  complete  the  clinical  trials  we  would  like  to  pursue  and
complete,  and  we  may  be  unable  to  commence  or  complete  clinical  trials  and  pursue  regulatory  approvals  in  accordance  with  our  current  timeline
expectations.

Our  current  financial  and  technical  resources  are  limited  and  not  sufficient  to  develop  all  of  the  product  candidates  to  which  we  hold  licenses  or  options  to
license. This may affect our efforts to develop and bring to market the product candidates currently in our portfolio and any candidates we may add to our portfolio in the
future.  Due  to  our  limited  resources,  we  have  curtailed,  and  may  be  required  to  further  curtail,  our  development  programs  and  clinical  and  nonclinical  development
activities that might otherwise have led, or lead, to more rapid progress in the development of our product candidates, or product candidates that we may in the future
choose to develop. We may make determinations with regard to the indications and clinical trials on which to focus our resources that result in our realization of less
than the full potential value of a product candidate. The decisions to allocate our research, management, personnel and financial resources toward particular indications
may  not  lead  to  positive  clinical  milestones  or  to  the  development  of  viable  commercial  products  and  may  divert  resources  from  better  opportunities.  Similarly,  our
decisions to delay or terminate development programs may also cause us to miss valuable opportunities, including the potential for some of our product candidates to
be first-in-category products.

As  a  result  of  financial  and  other  resource  constraints,  we  may  be  unable  to  commence  or  complete  our  planned  clinical  trials  or  prepare  and  submit
applications for marketing approval of our product candidates in accordance with our currently anticipated timelines. See also “Risks Related to Product Research &
Development, and Regulatory Approval – Delays in the commencement or completion of clinical testing of product candidates we

are developing or may develop in the future may occur due to any of a number of factors and could result in significantly increased costs and longer timelines and could
impact our ability to ever become profitable” below.

Our cash could be adversely impacted if a financial institution with which we have deposit or other accounts fails.

Our cash and cash equivalents we use to satisfy our working capital and operating expense needs are held in accounts at various financial institutions. The
balance held in deposit accounts often exceeds the Federal Deposit Insurance Corporation (“FDIC”) deposit insurance limit or similar government deposit insurance
schemes. Our cash and cash equivalents could be adversely impacted, including the loss of uninsured deposits and other uninsured financial assets, if one or more of
the financial institutions in which we hold our cash or cash equivalents fails or is subject to other adverse conditions in the financial or credit markets. For example, on
March 10, 2023, Silicon Valley Bank was closed by the California Department of Financial Protection and Innovation and taken into receivership by the FDIC. At that
time, substantially all of our cash and cash equivalents were held in accounts with Silicon Valley Bank and we could not access such accounts. While we were afforded
full access to our accounts on March 13, 2023 as a result of action taken by the U.S. Department of the Treasury, the Federal Reserve and the FDIC under the systemic
risk exception, there is no guarantee that the systemic risk exception will be relied upon to provide access to uninsured deposits and other assets in the future in the
event of the closure of a financial institution, or that such access would be afforded in a timely fashion. Any loss of our cash or cash equivalents or any delay in our
access  thereto  could,  among  other  risks,  adversely  impact  our  ability  to  pay  our  operating  expenses,  result  in  breaches  of  our  contractual  obligations,  or  result  in
violations of federal or state wage and hour laws if we are unable to pay our employees on a timely basis.

Women’s health has historically been an underfunded sector. Recently, a number of public companies focused in women’s health have failed to achieve
expected  commercial  success  and  struggled  to  access  sufficient  capital.  We  are  solely  focused  in  women’s  health  and  may  be  unfavorably  impacted  by
weak investor sentiment and a lack of interest in the category. Our ability to access capital and to advance our candidates could be adversely impacted.

We are solely focused in women’s health, and primarily in the areas of contraception, vaginal health, reproductive health, menopause, sexual health and fertility.
The  sector  has  historically  been  underfunded,  with  only  about  one  percent  of  healthcare  research  and  innovation  in  the  U.S.  invested  in  female-specific  conditions
beyond oncology according to market research. The failure of the women’s health sector to receive consistent and committed investment fuels investor sentiment that
market opportunities for new products in women’s health are limited. Our stock price and our ability to access additional capital on acceptable terms when needed may
be adversely impacted by unfavorable investor perception of market opportunities for women’s health products, and our business, operating results, financial condition
and prospects could suffer.     

Risks Related to Product Research & Development and Regulatory Approval

XACIATO is our first and only FDA-approved product. The FDA’s approval of XACIATO does not provide any assurance or predict that we will be successful
in developing or achieving regulatory approval of any other product candidate. If we are unable to successfully conduct and complete development of and
obtain  regulatory  approvals  for  our  investigational  products,  which  may  never  occur,  our  business  may  fail  and  you  could  lose  all  or  part  of  your
investment.

Historical  success  in  clinical  development  of  and  obtaining  regulatory  approval  for  a  product  candidate  does  not  guarantee  or  predict  future  successful
outcomes for other investigational products. Each of our development programs is unique and subject to substantial uncertainty of success inherent in pharmaceutical
and biopharmaceutical development.

Our pipeline consists entirely of investigational products, which we also refer to as product candidates, which means that they must successfully complete one
or more clinical studies to be considered for marketing approval and undergo a submission and review process with the FDA to obtain approval to be marketed in the
U.S., or a similar process with comparable regulatory authorities in other jurisdictions to be marketed anywhere outside of the U.S. FDA or other regulatory authority
approval may never be obtained. If we are unable to successfully complete development of and obtain regulatory approvals for our product candidates, our business
may fail and you could lose all or part of your investment.

Clinical  development  is  a  lengthy  and  expensive  process  with  an  inherently  uncertain  outcome.  Failure  to  successfully  develop  and  obtain  regulatory
approval to market and sell our product candidates, and in particular, Ovaprene and Sildenafil Cream, would likely adversely affect our business.

Our business depends on the successful clinical development and regulatory approval of our product candidates, and in particular, our lead product candidates,
which may never occur. The product candidates we develop require substantial clinical testing to demonstrate that they are safe and effective for their proposed uses.
Clinical testing is expensive, difficult to design and implement, can take many years to complete and its outcome is inherently uncertain. A failure of one or more clinical
trials could occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of success of later clinical trials, and interim
results of a particular clinical trial do not necessarily predict final results of that trial. Accordingly, while some of our product candidates have undergone clinical trials and
demonstrated  positive  results,  including  Ovaprene  and  Sildenafil  Cream,  there  is  no  guarantee  of  successful  outcomes  in  current  or  future  clinical  studies  of  these
product candidates or of obtaining marketing approval for any of them. For example, while PCT clinical trials have been used as a surrogate marker for contraceptive
effectiveness  and  our  PCT  clinical  trial  of  Ovaprene  met  its  primary  endpoint,  there  is  no  guarantee  Ovaprene  will  demonstrate  contraceptive  effectiveness  in  its
ongoing pivotal Phase 3 clinical study. As another example, while we believe the objectives of our exploratory Phase 2b RESPOND study of Sildenafil Cream were met
and enabled successful completion of an end-of-Phase 2 meeting with the FDA and alignment on key elements of the Phase 3 program for Sildenafil Cream, the co-
primary  efficacy  endpoints  of  the  Phase  2b  study  were  not  met  and  there  is  no  guarantee  that  Phase  3  clinical  studies  will  be  successful.  The  fact  that  the  active
pharmaceutical  ingredients  in  certain  of  our  product  candidates,  including  Sildenafil  Cream,  received  regulatory  approval  in  other  formulations  and/or  for  other
indications  does  not  guarantee  successful  development  of  our  product  candidates  for  their  proposed  intended  uses.  Clinical  trials  may  never  demonstrate  sufficient
safety and effectiveness to obtain the requisite regulatory approvals for our product candidates.

Even  if  we  conduct  and  complete  clinical  trials  for  our  product  candidates,  we  may  not  obtain  regulatory  approval  to  market  and  sell  any  of  them  on  the

timelines we anticipate, or at all, which would have a material adverse effect on our business and operations.

Outcomes of our clinical trials, particularly later-stage clinical trials, may significantly impact our stock price. If the results of our pivotal Phase 3 clinical
study of Ovaprene are not positive, our stock price could decline and our business and prospects may be adversely affected.

Ovaprene is one of our lead product candidates. If the results of our pivotal Phase 3 clinical study of Ovaprene are not positive or are perceived by third parties,
including  financial  market  participants,  as  not  positive,  our  business,  prospects  and  stock  price  could  suffer  significantly.  If  Ovaprene  fails  to  demonstrate  adequate
safety or contraceptive effectiveness in the Phase 3 study, we may determine to delay, scale back or terminate the program, and we may not realize any return on our
investment  in  the  program.  In  addition,  if  we,  the  investment  community,  potential  collaborators  or  the  FDA  view  the  topline  or  complete  results  of  the  study  as  not
positive, our stock price could decline significantly, our reputation may suffer, and our ability to raise additional capital to continue to operate as a going concern and
execute our business strategy could be adversely impacted.

Delays in the commencement or completion of clinical testing of our product candidates may occur due to any of a number of factors and could result in
significantly increased costs and longer timelines and could impact our ability to ever become profitable.

Clinical trials of our product candidates may not commence, progress or be completed as expected. Delays could significantly impact our product development
costs and timelines, as well as a product candidate’s market potential, if ultimately approved. The timing of initiation, conduct and completion of clinical trials and other
development activities for our product candidates may vary dramatically due to factors within and outside of our control and is difficult to predict accurately. We may
make statements regarding anticipated timing for commencement, completion of enrollment, and/or availability of results from our clinical studies, but those statements
are predictions based on significant assumptions and the actual timing of achievement of development milestones may differ materially from our predictions for a variety
of reasons.

lack of adequate capital and the need to obtain additional funding;

The commencement of clinical trials of our product candidates can be delayed for many reasons, including:
•
•
•

delays in obtaining guidance or authorizations from the FDA or foreign regulatory authorities;

delays in obtaining approval from the institutional review boards, or IRBs, of prospective clinical study sites;

61

delays in reaching agreement on acceptable terms with prospective CROs and clinical trial sites; or

delays in finalizing the trial design as a result of discussions with the FDA, foreign regulatory authorities, prospective clinical trial investigators or IRBs;

•
•
•
Once a clinical trial has begun, it may be delayed, suspended or terminated by us, an IRB, the FDA or other regulatory authorities as a result of the occurrence

inability to obtain sufficient quantities of clinical product supplies from our contract manufacturers and suppliers.

of any of a number of events or circumstances, including:

•
•
•
•
•
•
•
•
•
•
•

lack of adequate capital and the need to obtain additional funding;

failure to conduct the clinical trial in accordance with regulatory or IRB requirements;

slower than expected rates of participant recruitment and enrollment;

higher than anticipated participant drop-out rates;

failure of participants to use the investigational product as directed or to report data as per trial protocols;

inspection of the clinical trial operations or clinical trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold;

failure to achieve certain efficacy and/or safety standards;

participants experiencing severe undesirable side effects or other unexpected adverse events related to the investigational product;

disruptions in or insufficient supply of clinical trial material or inadequate quality of such materials;

failure of our CROs or other third-party service providers to meet their contractual obligations to us in a timely manner, or at all; or

delays in quality control/quality assurance procedures necessary for study database lock and analysis of unblinded data.

Unexpected serious adverse events or other undesirable side effects could arise during clinical development and interrupt, delay, or cause the termination of
clinical  trials,  and  require  us  to  conduct  additional  clinical  and  nonclinical  studies  that  were  not  part  of  our  development  plan,  which  could  significantly  increase  the
development  costs  and  timeline  for  a  program  and  adversely  impact  its  value  and  our  ability  to  continue  product  development.  These  events  may  also  cause  our
reputation to suffer and subject us to lawsuits.

As discussed elsewhere in this Risk Factors section, macroeconomic factors and events also have the potential to cause or contribute to significant delays in
commencement  and  completion  of  our  clinical  trials.  Global  supply  chain  disruptions  and  the  subsequent  effects  thereof  may  adversely  affect  the  ability  of  contract
manufacturers  to  manufacture  and  supply  our  clinical  trial  material.  Our  prospective  or  contracted  clinical  trial  sites  may  experience  resource  constraints,  including
staffing shortages, stemming from global or regional issues, such as a pandemic or other public health emergency, and become unable to allocate adequate resources
to reach agreements necessary to commence our clinical trials at their facilities or, even if agreements are in place, to conduct our clinical trials. For ongoing clinical
trials, macroeconomic factors or events, such as a global pandemic, may result in lower than anticipated subject enrollment and completion rates, including because
clinical  trial  sites  may  temporarily  close  or  reallocate  resources  away  from  clinical  research,  or  study  participants  may  withdraw  prior  to  receiving  study  treatment  or
discontinue their treatment or follow up visits to avoid medical settings or because they become sick or must care for a sick family member.

Significant clinical trial delays could have a material adverse impact on our financial condition and results of operations by substantially increasing the costs of
our development programs. Significant clinical trial delays also could jeopardize our ability to meet obligations under agreements under which we license our rights to
our product candidates, allow other companies to bring competitive products to market before we do, shorten any period of market exclusivity we may otherwise have
under our patent rights, and weaken our negotiating position in discussions with potential collaborators, any of which could impair our ability to successfully complete
development of or commercialize our product candidates, if ultimately approved. Any significant delays in commencement or completion of clinical trials of our product
candidates, or the suspension or termination of a clinical trial, could materially harm our business, financial condition and results of operations.

62

Delays in the manufacture of our clinical supplies as well as other supply chain disruptions could postpone the initiation of or interrupt clinical studies,
extend  the  timeframe  and  cost  of  development  of  our  product  candidates,  delay  potential  regulatory  approvals  and  impact  the  commercialization  of  any
approved products.

The manufacture of our product candidates is complex and subject to compliance with extensive regulatory requirements, and in most cases we rely on single
source  contract  manufacturers  and  suppliers.  As  a  result,  we  face  significant  risks  of  manufacturing  and  supply  delays  and  disruptions  that  may  be  difficult  and
expensive to resolve and may cause substantial delays in the development and regulatory approval of our product candidates or the commercialization of any approved
product. To date, our clinical-stage product candidates have been tested in a relatively small number of clinical study participants. Significant scale-up of manufacturing
will be required to provide adequate supplies of our product candidates for larger Phase 2 and Phase 3 clinical trials and may take longer and be more expensive than
anticipated,  potentially  having  a  significant  negative  impact  on  our  development  costs  and  timelines.  We  have,  and  we  expect  we  will  continue  to,  face  multiple
challenges as our contract manufacturers scale their processes to provide supplies for larger clinical trials or commercial production including, among others, potential
difficulties  with  process  scale-up,  process  reproducibility,  stability  and  purity  issues,  compliance  with  cGMP,  lot  consistency,  and  timely  availability  of  acceptable  raw
materials.

For  example,  the  ongoing  pivotal  clinical  study  of  Ovaprene  will  require  far  more  clinical  product  supplies  than  were  manufactured  for  prior  clinical  and
nonclinical  studies  combined.  A  substantial  scale  up  in  production  was  necessary  to  meet  the  study’s  requirements  and  required  more  time  and  expense  than
anticipated. Additional clinical supplies must be produced to complete the study and manufacturing disruptions may occur that extend the overall timeline and cost to
complete the study. Under our agreement with ADVA-Tec, we are dependent on ADVA-Tec and its contract manufacturer, Poly-Med, Inc., for all Ovaprene clinical and
commercial  product  supplies,  and  we  do  not  control  these  third  parties  and  have  limited  influence  the  efforts  and  resources  they  expend  to  meet  our  supply
requirements. Furthermore, some of the key raw materials and components of Ovaprene have only a single source of supply. Global supply chain disruptions may also
result in delays in and increased costs for the manufacture and supply of sufficient quantities of Ovaprene to meet the pivotal clinical study’s requirements.

The  manufacture  of  our  product  candidates  is  subject  to  extensive  regulation.  The  finished  products  (and  their  APIs)  used  in  clinical  trials  or  approved  for
commercial sale must be manufactured in accordance with cGMP requirements in the U.S. that are enforced by the FDA and must comply with applicable requirements
of  foreign  regulatory  authorities  for  sales  outside  of  the  U.S.  These  regulations  govern  manufacturing  processes  and  procedures,  including  record  keeping  and  the
implementation and operation of quality systems to control and assure the quality of investigational products and products approved for sale. Poor control of production
processes  can  lead  to  the  introduction  of  contaminants  or  to  inadvertent  changes  in  the  properties  or  stability  of  a  product  that  may  result  in  closure  of  the
manufacturing  facility  for  an  extended  period  of  time  to  investigate  and  remedy  the  contamination  or  inadvertent  change.  In  addition,  deviations  anywhere  in  the
manufacturing  process  could  cause  our  product  candidates  to  perform  differently  and  affect  the  results  of  clinical  trials.  Further,  even  minor  deviations  in  the
manufacturing process, including filling labeling, packaging, storage and shipping, and quality control and testing, may result in shipment delays, lot failures, recalls or
spoilage,  and  delay  or  disrupt  our  clinical  studies  or  commercial  supply  of  any  approved  product.  If  our  contract  manufacturers  are  unable  to  produce  sufficient
quantities  of  our  product  candidates  (or  their  APIs)  for  clinical  trials  or,  if  approved,  for  commercialization  at  acceptable  quality  levels,  our  development  and
commercialization efforts would be impaired, which could have a material adverse effect on our business, financial condition and results of operations.

As product candidates progress through the development process, it is not uncommon that manufacturing methods are altered along the way in an effort to
optimize yield, manufacturing batch size, minimize costs, achieve consistent quality and results, or to comply with regulatory authority requirements. Any such changes
carry risk that they will not achieve the intended objectives. If and when changes are made to the manufacturing process of our product candidates (or their APIs), we
may  be  required  by  the  FDA  or  foreign  regulatory  authorities  to  conduct  bridging  clinical  or  nonclinical  studies  or  repeat  one  or  more  clinical  trials  to  demonstrate
comparable identity, strength, quality and purity of the product candidate before and after such changes, which could significantly increase development costs and delay
regulatory approval or disrupt commercial supply. These manufacturing and supply risks are similarly applicable to any product or product candidate we license to a
commercial collaborator and could adversely impact the timing or amount of potential milestone and royalty payments to us.

In addition, our cost of goods for our product candidates is at an early stage of development. The cost to manufacture our product candidates at commercial
scale is difficult to predict currently. We may need to alter the materials, equipment or processes for making our product candidates in order to yield commercially viable
products. As discussed above, manufacturing changes could increase development costs and timing and may not achieve the

63

intended objectives. Manufacturing costs may negatively impact the commercial viability of our product candidates, if approved.

See also “Risks Related to Our Dependence on Third Parties- We do not have, and we do not have plans to establish, our own manufacturing capabilities and
instead rely on third-party suppliers and manufacturers for clinical study materials, including multiple single source suppliers and manufacturers. If these third parties do
not  perform  as  we  expect,  do  not  maintain  their  regulatory  approvals  or  become  subject  to  negative  circumstances,  it  could  delay,  prevent  or  impair  our  product
development  or  commercialization  efforts,  or  those  of  our  collaborators,  and  harm  our  business,”  and  “-  In  some  cases,  we  may  be  contractually  required  to  obtain
clinical or commercial product supplies from specific third parties or there may be a limited number of third-party suppliers of raw materials and other components of our
product candidates or future products, which may heighten our dependence on those third parties and the risk of manufacturing disruptions” below.

Many of our product candidates, including Ovaprene, will or may be considered combination products by the FDA and other regulatory authorities, which
could  increase  the  complexity,  cost  and  timeline  for  their  development  and  regulatory  approvals.  A  change  in  the  FDA’s  prior  determination  that  CDRH
would lead the review of a marketing application for Ovaprene would adversely impact Ovaprene’s development timeline and significantly raise our costs to
complete clinical development and obtain regulatory approval for Ovaprene.

To  the  extent  our  product  candidates  meet  the  FDA’s  or  any  other  regulatory  authority’s  definition  of  a  combination  product,  the  regulatory  approval
requirements can be more complex and costly because in addition to the individual regulatory requirements for each component, e.g., a drug and a medical device,
additional combination product regulatory requirements may apply. The cost and timeline for development of product candidates determined to be combination products
may  be  substantially  greater  than  product  candidates  that  are  not  considered  combination  products.  See  also  ITEM  1.  "BUSINESS–Government  Regulation–U.S.
Government Regulation–FDA Review and Approval Process for Combination Products,” above.

Ovaprene is composed of both device and drug components and is considered a combination product by the FDA. The process for obtaining FDA approval of
Ovaprene  will  require  compliance  with  complex  procedures  because  concordance  between  two  centers  of  the  FDA  (CDRH  and  CDER)  is  necessary.  Ovaprene
previously  underwent  a  request  for  designation,  or  RFD,  process  with  the  FDA  that  determined  that  CDRH  would  lead  the  review  of  a  PMA  for  potential  marketing
approval  of  this  product  candidate.  If  the  designation  were  to  be  changed  to  CDER,  or  if  either  center  were  to  institute  additional  requirements  for  the  approval  of
Ovaprene, we could be required to complete clinical studies with more patients and over longer periods of time than is currently anticipated. This would significantly
increase the anticipated cost and timeline to completion of Ovaprene’s development and require us to raise additional funds. Based on discussions with the FDA, we
believe that if our ongoing pivotal clinical study of Ovaprene is successful, the FDA will not require additional clinical studies to support the PMA for Ovaprene. However,
the FDA may determine that the results of the study are not sufficiently robust or convincing and require additional clinical and/or nonclinical studies prior to approval of
Ovaprene.  Because  Ovaprene  is  one  of  our  lead  product  candidates,  the  impact  of  either  a  change  in  the  lead  FDA  review  center  or  the  imposition  of  additional,
currently unplanned requirements for approval could be significant to us and have a material adverse effect on the prospects for developing Ovaprene, as well as on our
business  and  our  financial  condition.  See  also  “The  commercial  success  of  Ovaprene  will  depend  on  market  acceptance  of  a  hormone-free  monthly,  intravaginal
product, availability and effectiveness of alternative contraceptive products and women's preferences, as well as the success of Bayer’s marketing and sales efforts”
below.

The  factors  contributing  to  female  sexual  dysfunction  disorders,  including  FSAD,  are  complex  and  there  is  limited  clinical  trial  precedent  from  which  to
draw experience, making the design and execution of a clinical trial that demonstrates effectiveness of Sildenafil Cream in treating FSAD more inherently
challenging and uncertain compared with investigational products for many other conditions.

There are currently no FDA-approved pharmacologic treatments for female sexual arousal disorder, or FSAD, and there is no precedent program to reference in
the design of our clinical trials for Sildenafil Cream. Female sexual dysfunction disorders in women vary in nature and may be the result of a variety of physiological and
psychological  factors.  Given  the  variability  of  factors  contributing  to  the  underlying  condition,  and  the  product  candidates'  attributes,  clinical  studies  to  evaluate
effectiveness in any subset of the conditions under the umbrella of Sexual Dysfunction, such as FSAD, are complex. While we worked with experts to develop novel
patient  reported  outcome  (PRO)  instruments  for  our  exploratory  Phase  2b  RESPOND  study  of  Sildenafil  Cream,  tested  the  potential  PRO  instruments  in  a  content
validity study, reviewed the results of that study with the FDA and aligned with the FDA on the Phase 2b study design, the Phase 2b RESPOND study proved more
difficult to enroll than anticipated given the enrollment criteria for the study, particularly the requirement that the partner be enrolled in the study. Moreover, the Phase 2b

64

RESPOND study did not demonstrate statistical significance for the co-primary or secondary efficacy endpoints, although we determined that topline data supported
continued clinical development of Sildenafil Cream and further analysis of the study data identified certain subsets of participants that achieved clinically meaningful and
statistically significant improvement in certain items relating to the co-primary efficacy endpoints and data from the RESPOND study enabled successful completion of
an end-of-Phase 2 meeting with the FDA and ongoing feedback from the FDA to align on key elements of the Phase 3 program for Sildenafil Cream.

Sildenafil Cream is designed to work primarily by increasing blood flow to the genital tissue. Therefore, identifying and enrolling patients in our clinical trials of
Sildenafil  Cream  for  whom  inadequate  blood  flow  to  the  genital  tissue  is  the  primary  contributor  to  their  arousal  disorder  is  critical.  If  we  fail  to  screen  properly,  and
instead enroll patients with different contributing factors, the results of our clinical trials are unlikely to demonstrate effectiveness of Sildenafil Cream. Conversely, trying
to  screen  out  patients  with  different  contributing  factors  may  slow  enrollment  in  a  study,  delay  its  completion  and  increase  its  costs.  In  our  exploratory  Phase  2b
RESPOND  study,  we  experienced  a  slower  than  anticipated  pace  of  enrollment  given  the  enrollment  criteria  for  the  study,  which  lengthened  our  original  estimated
timeline for the study. We may experience delays in future clinical studies of Sildenafil Cream relative to our communicated expectations due to the novel nature of the
studies and the complexities of the condition it is intended to treat, which may significantly lengthen clinical study timelines, increase overall costs, and may lead to
unfavorable results.

With respect to any clinical study of Sildenafil Cream, even if we can identify and enroll a sufficient number of women for whom inadequate blood flow to the
genital  tissue  is  the  primary  contributing  factor  to  their  arousal  disorder,  there  is  no  guaranty  that  the  use  of  Sildenafil  Cream  will  improve  their  general  feelings  of
arousal or that the PRO instruments we utilize to measure the effectiveness of Sildenafil Cream in the study will adequately capture their genital arousal response. We
expect to conduct two Phase 3 studies to support an NDA for Sildenafil Cream. Given the multiple factors contributing to arousal disorders and the novelty of the clinical
endpoints  that  may  be  utilized  to  measure  effectiveness  of  Sildenafil  Cream  in  treating  FSAD,  we  may  be  required  to  conduct  multiple  clinical  trials  in  large  patient
populations, extending the timeline and increasing the cost of development for Sildenafil Cream, without any guarantee of positive results. If we are unable to efficiently
and  successfully  advance  Sildenafil  Cream  through  clinical  development,  our  business,  operating  results  and  financial  conditional,  as  well  as  our  stock  price,  could
suffer.

Interim,  topline  and  preliminary  data  from  our  clinical  trials  that  we  announce  or  publish  from  time  to  time  may  change  as  more  patient  data  become
available  and  are  subject  to  audit  and  verification  procedures  that  could  result  in  material  changes  in  the  final  data,  and  others,  including  regulatory
authorities, may not agree with our interpretation of study data.

From time to time, we may publicly disclose interim, preliminary or topline data from our clinical studies, which are based on a preliminary analysis of then-
available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular
study  or  trial.  We  also  make  assumptions,  estimations,  calculations  and  conclusions  as  part  of  our  analysis  of  data,  and  we  may  not  have  received  or  had  the
opportunity to fully and carefully evaluate all data. As a result, the topline results of clinical trials we report may differ from final results reported for those studies, or
different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Topline data also remain subject to audit
and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, topline data should
be viewed with caution until the final, complete data are available.

Interim data from clinical trials are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more
patient data become available. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. There can be no
guarantee that a favorable interim analysis will result in a favorable final result at the completion of the clinical trial.

Further,  others,  including  regulatory  authorities,  may  not  accept  or  agree  with  our  assumptions,  estimates,  calculations,  conclusions  or  analyses  or  may
interpret or weigh the importance of study data differently than we do, which could impact the value of the particular program, the approvability or commercialization of
the  particular  product  candidate  or  product  and  our  company  in  general.  In  addition,  the  information  we  choose  to  publicly  disclose  regarding  a  particular  study  or
clinical trial is based on what is typically an extensive set of data and analyses, and investors and others may disagree with the information we determine is the material
or  otherwise  appropriate  information  to  include  in  our  public  disclosure.  Information  we  determine  not  to  publicly  disclose  may  ultimately  be  deemed  significant  with
respect to future decisions, conclusions, views, activities or otherwise regarding a particular product candidate, product or our business. If the topline data that we report
differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and

65

commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Our business depends on obtaining regulatory approval to market our product candidates in a timely manner, in particular, FDA approval. The regulatory
approval processes of the FDA and comparable foreign authorities are expensive, lengthy, time-consuming, and inherently unpredictable. If we are not able
to obtain regulatory approvals for our product candidates, our ability to generate product revenue will be materially impaired.

Our product candidates and the activities associated with their development and commercialization, including their design, testing, manufacture, release, safety,
efficacy, regulatory filings, recordkeeping, labeling, storage, approval, advertising, promotion, sale and distribution, are subject to comprehensive regulation by the FDA,
other  regulatory  authorities  in  the  U.S.,  and  comparable  authorities  in  other  countries  or  jurisdictions  where  we  seek  to  test  or  market  our  product  candidates.  The
process of obtaining marketing approvals in the U.S. and elsewhere is expensive, may take many years and can vary substantially based upon a variety of factors,
including the type, complexity and novelty of the product candidates involved. In addition, requirements for approval may change over time and our current development
plans may not accurately anticipate all applicable requirements for marketing approval by the FDA or comparable regulatory authorities for jurisdictions outside the U.S.

Our  success  depends  on  our  ability  to  obtain  regulatory  approvals  for  our  product  candidates  in  a  timely  and  cost-efficient  manner.  Even  if  we  successfully
complete nonclinical studies, clinical studies, manufacturing and other required activities, we may still experience delays in our efforts to obtain marketing approvals for
any of our product candidates. Marketing approval applications require the submission of extensive clinical and nonclinical data and supporting information to establish
the safety and efficacy of our product candidates for the specified indication. The process of responding to the FDA or other regulatory authorities’ information requests
in the review process, potentially preparing for and appearing at a public advisory committee or oral hearing, and preparing our third-party manufacturers and clinical
investigators  to  successfully  complete  inspections  by  the  FDA  or  other  regulatory  authorities  during  the  approval  process  requires  significant  human  and  financial
resources.

We may change the development plan for a product candidate as a result of changes during the development period in the FDA’s marketing approval policies or
the amendment or enactment of additional statutes or regulations, updated interpretations of applicable policies, statutes or regulations, or upon review of outcomes of
other similar product candidates under development. This could significantly lengthen our development timelines and cost.

The FDA and comparable regulatory authorities in other countries have substantial discretion in the approval process and may refuse to accept any application
or may decide that the data are insufficient for approval and require additional clinical or nonclinical studies or changes in the manufacturing process or facilities, even if
we  had  previously  aligned  with  the  relevant  regulatory  authorities  on  such  data  and  other  requirements.  We  cannot  assure  you  that  we  will  obtain  any  additional
marketing approvals for our product or product candidates in any jurisdiction.

The announcement of new requirements by the FDA, the failure of a competitive product to receive regulatory approval, or the receipt of a complete response
letter from the FDA by another company pursuing the FDA's 505(b)(2) pathway for product candidates identical to or similar to ours, any of which may have implications
for our proposed regulatory authorization pathways, could impact how investors and potential strategic collaborators view the development risks associated with our
product  candidates.  Changing  testing  or  manufacturing  requirements  for  our  product  candidates  or  for  product  candidates  deemed  to  be  comparable  to  ours  may
adversely impact our financial resources, our development timelines and may harm the perception held by others of our business.

We expect to utilize the FDA’s Section 505(b)(2) pathway for most of our current product candidates and if that pathway is not available, the development of
our  product  candidates  will  likely  take  significantly  longer,  cost  significantly  more  and  entail  significantly  greater  complexity  and  risk  than  currently
anticipated, and, in any case, may not be successful.

We intend to develop and seek approval for many of our product candidates, including Sildenafil Cream, pursuant to the FDA’s 505(b)(2) pathway. If the FDA
determines that we may not use this regulatory pathway, then we would need to seek regulatory approval via a “full” or “stand-alone” NDA under Section 505(b)(1) of
the FDCA. This would require us to conduct additional clinical trials and nonclinical testing, provide additional safety and efficacy data and other information, and meet
additional  standards  for  regulatory  approval.  If  this  were  to  occur,  the  time  and  financial  resources  required  to  obtain  FDA  approval,  as  well  as  the  development
complexity  and  risk  associated  with  these  programs,  would  likely  substantially  increase,  which  could  have  a  material  adverse  effect  on  our  business  and  financial
condition.

The  Drug  Price  Competition  and  Patent  Term  Restoration  Act  of  1984,  informally  known  as  the  Hatch-Waxman  Act,  added  Section  505(b)(2)  to  the  FDCA.

Section 505(b)(2) permits the filing of an NDA where at least

66

some of the information required for approval comes from studies and information that were not conducted by or for the applicant and for which the applicant has not
obtained a right of reference. Section 505(b)(2), if applicable to us under the FDCA, would allow an NDA we submit to the FDA to rely in part on data in the public
domain  or  the  FDA’s  prior  conclusions  regarding  the  safety  and  effectiveness  of  approved  compounds,  which  could  expedite  our  development  programs  relative  to
seeking approval under the 505(b)(1) regulatory pathway.

If  the  FDA  changes  its  505(b)(2)  policies  and  practices  or  if  Congress  were  to  amend  the  statute  to  alter  the  currently  available  regulatory  pathway,  it  could
delay or even prevent the FDA from approving any NDA we submit under Section 505(b)(2). In addition, the pharmaceutical industry is highly competitive, and Section
505(b)(2) NDAs are subject to special requirements designed to protect the patent rights of sponsors of previously approved drugs referenced in a Section 505(b)(2)
NDA. Even if we are able to utilize the Section 505(b)(2) regulatory pathway for one or more of our candidates, there is no guarantee this would ultimately lead to faster
product development or earlier approval.

Moreover,  any  delay  resulting  from  our  inability  to  pursue  the  FDA's  505(b)(2)  pathway  could  result  in  new  competitive  products  reaching  the  market  more
quickly than our product candidates, which may have a material adverse impact on our competitive position and prospects. Even if we are allowed to pursue the FDA's
505(b)(2) pathway, we cannot assure you that our product candidates will receive the requisite approvals for commercialization.

Our clinical-stage product candidates have only been tested in a small number of women over short periods of use and no data exists regarding a potential
increase in fetal abnormalities in pregnant women.

If our clinical-stage product candidates, including Ovaprene and Sildenafil Cream, are successful in their clinical development, we expect that women of child-
bearing age will use them, and potentially for many months or years. To date, human clinical studies of these product candidates have been for relatively short periods
of time and these product candidates lack safety data over longer periods of use. For example, while we believe the risk of adverse fetal development from using these
product candidates is low, the impact of these product candidates on fetal development has not been studied and there are no adequate or well-controlled studies of
these  product  candidates  in  pregnant  women.  Thus,  the  risk  of  adverse  fetal  development  from  any  one  or  more  of  these  product  candidates  may  be  greater  than
expected. Should any of these product candidates be shown to increase the risk of adverse fetal development, our ability to develop those or other product candidates
would be substantially impaired, our business prospects and operations would be materially harmed, and we could also be subject to potential claims and lawsuits.

Pre-clinical product candidates may not be valued by investors and may be difficult to fund.

Given their early stage of development and the lack of data, many pre-clinical assets are often perceived as having low valuations by investors and potential
strategic collaborators, such as pharmaceutical companies. Our investment of time and resources in such assets may not be appreciated or valued. As a result, it may
be  difficult  for  us  to  fund  such  programs.  Additionally,  past  receipt  of  grant  funding  may  not  be  predictive  of  our  ability  to  secure  additional  grants  to  fund  further
development  of  a  program.  Our  portfolio  includes  several  pre-clinical  stage  programs  and  if  they  fail  to  be  adequately  valued  by  investors  or  potential  strategic
collaborators, our business, financial condition and stock price may be adversely affected.

Several of our product candidates are in pre-clinical stages of development and may never advance to clinical development.

Pre-clinical studies refer to a stage of research that begins before clinical trials (testing in humans) can begin, and during which important feasibility, iterative
testing and drug safety data are collected. Because of their early nature, pre-clinical product candidates tend to carry a higher risk of failure as compared with clinical-
stage assets. Pre-clinical candidates must generate sufficient safety and efficacy data through in vitro studies, animal studies and a variety of tests before they can be
considered appropriate for testing in humans. The development risks, timeline and cost of pre-clinical assets can be high because of the unknowns and absence of
data. It can be difficult to identify relevant tests and animal models for pre-clinical studies. Even if the results from our pre-clinical studies are favorable, we still may not
be able to advance the candidates into clinical trials. If pre-clinical studies of product candidates do not generate strong data, our pre-clinical stage programs may never
progress to clinical development and may prove to be worthless.

The grants supporting the DARE-LARC1 and DARE-LBT programs do not guarantee that pre-clinical development will be successful or that we will be able
to fund their clinical development in the future.

The grants supporting pre-clinical development of DARE-LARC1 and DARE-LBT, including the grant agreement under which we were awarded up to $48.95
million  in  non-dilutive  funding  for  pre-clinical  development  of  DARE-LARC1,  do  not  guarantee  that  pre-clinical  development  will  be  successful,  or,  even  if  we  are
successful with all

67

specified  pre-clinical  activities,  that  we  will  be  able  to  fund  their  future  clinical  development.  Further,  while  we  received  aggregate  payments  of  approximately  $28.4
million under the 2021 DARE-LARC1 grant agreement as of December 31, 2023, additional payments are contingent upon the DARE-LARC1 program’s achievement of
specified  development  and  reporting  milestones  during  the  grant  period  and  our  compliance  with  other  obligations  under  the  agreement,  and  there  is  no  assurance
those milestones will be achieved or that we will receive additional payments or the full potential amount of the grant.

Risks Related to Our Dependence on Third Parties

Our existing product development and commercialization collaborations are important to our business, and future collaborations may also be important to
us. If we are unable to maintain any of these collaborations, if these collaborations are not successful, or if we are unable to establish additional strategic
collaborations, our business and prospects may be materially harmed.

We  have  limited  resources  and  no  internal  sales,  marketing  or  distribution  capabilities.  A  key  aspect  of  our  strategy  is  to  establish  collaborations  with  third
parties, such as large and mid-size pharmaceutical companies and other third parties with the relevant R&D and/or commercial expertise and infrastructure to help bring
our  product  candidates  to  market.  We  currently  do  not  expect  to  directly  market,  sell  or  distribute  any  of  our  products  that  receive  regulatory  approval,  and  instead
intend to enter into agreements with third parties to market, sell and distribute and provide related support services for those products. For example, we have entered
into out-license agreements with third parties for the commercialization of XACIATO and, if approved, Ovaprene. We also have a CRADA for the conduct of a pivotal
clinical  study  of  Ovaprene  with  NICHD.  We  intend  to  seek  additional  strategic  collaborations.  However,  these  collaborations  make  the  successful  development  and
commercialization of our products and product candidates dependent upon the performance of third parties. By entering into strategic collaborations, we may relinquish
control  over  important  elements  of  product  development  and  commercialization,  and  the  collaborator  may  fail  to  develop  or  effectively  commercialize  the  applicable
products or product candidates. In addition, in the case of commercial collaborations, our product revenues, may be lower than if we were to sell and distribute products
that we develop ourselves.

Our existing collaborations, and any future strategic collaborations we establish, involve significant risks to the success of the product, including that:

•

•

•

•

•

•

•

•

•

collaborators may have significant discretion in determining the efforts and resources that they will apply to these collaborations;

collaborators may not perform their obligations as expected;

collaborators may not pursue development or commercialization of a product or product candidate or elect not to continue or renew a collaboration based
on clinical or nonclinical study results, changes in the collaborators' strategic focus or available funding, or external factors, such as an acquisition, a public
health emergency, or macroeconomic events or conditions, that cause them to divert resources to other initiatives or create competing priorities;

collaborators may refuse to perform clinical studies or other development work required for approval in a particular jurisdiction outside the U.S.;

collaborators  may  delay  or  stop  clinical  studies,  provide  insufficient  funding  for  or  abandon  a  clinical  program,  repeat  or  conduct  new  clinical  studies  or
require a new formulation of a product or product candidate for clinical testing;

collaborators could independently, or together with third parties, develop and commercialize products that compete directly or indirectly with our products or
product candidates if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized under terms
that are more economically attractive than ours;

collaborators with marketing and distribution rights to one or more of our products may not commit sufficient resources to the marketing and distribution of
such product or products;

disagreements  with  collaborators,  including  disagreements  over  proprietary  rights,  contract  interpretation,  or  product  development  or  commercialization
strategy,  might  cause  delays  or  termination  of  the  research,  development  or  commercialization  of  our  products  or  product  candidates,  might  lead  to
additional  responsibilities  for  us  with  respect  to  products  or  product  candidates,  or  might  result  in  litigation  or  arbitration,  any  of  which  would  be  time-
consuming and expensive;

collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to invite litigation
that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation;

68

•

•

•

collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability;

collaborators  may  violate,  or  be  investigated  for  potentially  violating,  health  care  compliance  and  related  laws  and  regulations,  which  may  expose  us  to
litigation, enforcement actions or inquiries, or other potential liability; and

collaborations may be terminated for the convenience of the collaborator and, if terminated, could significantly delay product development and commercial
launch and increase the cost to us to pursue further development or commercialization of the applicable product or product candidate. For example, our
out-license  agreements  for  XACIATO  and  Ovaprene  and  the  CRADA  with  NICHD  may  be  terminated  by  the  counterparty  for  convenience  upon  the
completion of a specified notice period, subject to limited restrictions.

If  a  collaborator  terminates  its  agreement  with  us  or  if  a  collaboration  does  not  result  in  the  successful  development  of  any  product  candidates  and/or
commercialization  of  any  approved  products,  we  may  not  receive  any  future  royalty  revenue,  commercial  milestones  or  other  revenues  under  the  collaboration,  our
development  programs  may  not  be  funded  as  we  expect,  and  our  ability  to  establish  another  collaboration  for  the  applicable  product  or  product  candidate  may  be
negatively impacted. We may be unable to replace any commercial collaborator with an alternate third party on a timely or commercially reasonable basis, or at all. See
also, “Risks Related to Our Financial Position and Capital Needs- If one of our commercial collaborators terminates its exclusive license agreement with us or fails to
perform as expected, our need for additional capital may significantly increase,” above and “We rely on, and intend to continue to rely on, third parties for the execution
of  significant  aspects  of  our  product  development  programs.  Failure  of  these  third  parties  to  successfully  carry  out  their  contractual  duties,  comply  with  regulatory
requirements  and  applicable  law,  or  meet  expected  deadlines  may  cause  significant  delays  in  our  development  timelines  and/or  failure  of  our  programs,”  below.
Moreover, the risks relating to product development, regulatory approval and commercialization and compliance with health care related laws and regulations described
in this report also apply to the activities of our collaborators.

Except to the extent of any license fees or milestone payments under our current and any future collaboration agreements, because we currently have only one
FDA-approved product, our ability to generate revenue over the next several years will largely be dependent on royalties and net sales-based milestones under our
exclusive license agreement with Organon. Accordingly, our revenues may be dependent on Organon's ability to successfully market, sell and distribute XACIATO and
to perform its contractual obligations. There is no assurance that commercialization of XACIATO in the U.S. will be successful, or that Organon will pursue development
and commercialization of XACIATO outside of the U.S. The amount of royalty and milestone payments we will receive under the license agreement is uncertain. Apart
from  Organon's  diligence  obligation  under  our  license  agreement,  we  have  no  control  over  the  efforts  and  resources  Organon  devotes  to  the  marketing  and  sale  of
XACIATO. The occurrence of any of the risks described above could negatively impact the commercial success of XACIATO and have a material adverse effect on our
business, financial condition and results of operations.

Termination  of  the  CRADA  by  NICHD  or  by  us  could  significantly  delay  the  conduct  and/or  completion  of  the  Phase  3  study  of  Ovaprene  and  significantly
increase the overall timeline and costs for development of Ovaprene. Though the CRADA has a five-year term, either party may terminate it for any reason or for no
reason upon 30 days’ prior written notice to the other party. If the CRADA is terminated before completion of the Phase 3 study of Ovaprene, NICHD will cooperate with
us to transfer the data and the conduct of the study to us or our designee and will continue to conduct the study for so long as necessary to enable such transfer to be
completed without interrupting the study. If we terminate the CRADA before the completion of any active study protocol, we generally will be responsible for providing
sufficient clinical supplies of Ovaprene to NICHD in order to complete the study. NICHD may retain and use the cash payments we have made under the CRADA for up
to one year after expiration or termination to cover costs associated with the conduct of activities described under the research plan in the CRADA that were initiated
prior  to  expiration  or  termination.  If  we  fail  to  make  any  scheduled  payment  to  NICHD  under  the  CRADA,  NICHD  is  not  obligated  to  carry  out  R&D  activities  until  it
receives the funds. We have paid NICHD $5.0 million under the CRADA to date. Under the terms of the CRADA, a final payment of $0.5 million was due in the second
quarter of 2023. Pursuant to our discussions with NICHD, we expect to make the final payment in the third quarter of 2024. Suspension by NICHD of activities under the
CRADA  or  termination  by  NICHD  or  by  us  of  the  CRADA  could  have  a  material  adverse  effect  on  the  Phase  3  study  of  Ovaprene  and  on  our  business,  results  of
operations and financial condition, and may cause the market price of our common stock to decline.

We  face  significant  competition  in  seeking  strategic  collaborations.  Collaborations  can  also  be  complex  and  time-consuming  arrangements  to  negotiate  and
document. If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may have to curtail the development of
a product or

69

product  candidate,  reduce  or  delay  one  or  more  of  our  other  development  programs,  delay  or  reduce  the  scope  of  any  commercial  readiness  activities,  delay
commercialization,  or  increase  our  expenditures  and  undertake  development  or  commercialization  activities  at  our  own  expense.  Our  success  in  entering  into  a
definitive agreement for any collaboration will depend upon, among other things, our assessment of the prospective collaborator’s resources and expertise, the terms of
the proposed collaboration and the proposed collaborator’s evaluation of several factors. Those factors may include the design and outcomes of our clinical studies, the
likelihood  of  approval  by  regulatory  authorities,  the  potential  market  for  the  product,  the  costs  and  complexities  of  manufacturing  and  delivering  such  product  to
customers, the potential of competing products, the strength of the intellectual property and other potential sources of market exclusivity for such product, the market
performance of other products we developed, and industry and market conditions generally. The prospective collaborator may also have opportunities to collaborate
with  third  parties  on  products  or  technologies  that  would  compete  with  our  products  or  product  candidates  and  will  evaluate  whether  those  opportunities  are  more
attractive than a collaboration with us. We face competition in our search for collaborators from other biotechnology and pharmaceutical companies worldwide, many of
which are larger and able to offer more attractive deals in terms of financial commitments, contribution of human resources, or development, manufacturing, regulatory
or  commercial  expertise  and  support.  Inadequate  capitalization  of  our  company,  or  the  perception  thereof,  could  negatively  affect  our  negotiating  leverage  in
transactions.

We may also be restricted under existing collaboration agreements from entering into other collaborations on certain terms with other potential collaborators.
For example, the terms of our exclusive license agreement also provide Organon exclusive worldwide rights of first negotiation for specified potential future products of
ours, which may increase the complexity and time required, or otherwise inhibit our ability to transfer, license, sublicense, assign, grant or otherwise dispose of any
rights in those potential future products to a third party, and lead to delays in their development and commercialization.

If  we  are  not  successful  in  attracting  collaborators,  entering  into  collaborations  on  acceptable  terms  and  maintaining  our  collaborations  for  the  products  we
develop, we may not complete development of or obtain regulatory approval for such products and product candidates, or if we obtain regulatory approval, commercial
launch may be delayed and market penetration could be limited. In such event, our ability to generate revenues from such products and achieve or sustain profitability
would be significantly hindered which would materially harm our business and financial condition.

We do not have, and we do not have plans to establish, our own manufacturing capabilities and instead rely on third-party suppliers and manufacturers for
our clinical study supplies, including multiple single source suppliers and manufacturers. If these third parties do not perform as we expect, fail to maintain
their regulatory approvals or become subject to negative circumstances, it could delay, prevent or impair our product development or commercialization
efforts, or those of our collaborators, and harm our business.

We do not own or operate, and we currently have no plans to establish, facilities for manufacturing, storage and distribution, or testing of product candidates.
We rely and expect to continue to rely on third parties to supply and manufacture our product candidates and other materials necessary to commence and complete
pre-clinical  testing,  clinical  trials  and  other  activities  required  for  regulatory  approval  of  our  product  candidates,  including  qualification  of  equipment,  developing  and
validating methods, defining critical process parameters, releasing component materials, and conducting stability testing. In addition, we expect to continue to rely on
third  parties  for  commercial  production  and  supplies  of  any  future  products.  This  reliance  on  third-party  manufacturers  and  suppliers  subjects  us  to  inherent
uncertainties related to product safety, availability, quality and cost.

Our product candidates (including their component materials) must be manufactured, packaged, tested, and labeled in accordance with our specifications and
in  conformity  with  cGMP  and  other  applicable  regulatory  requirements,  which  requires  dedication  of  substantial  resources  to  specialized  personnel,  facilities  and
equipment  and  sophisticated  quality  assurance,  quality  control,  recordkeeping  procedures.  While  our  employees  and  consultants  monitor  and  audit  our  CMOs’
manufacturing processes and systems, we have limited control over our CMOs and they may fail to perform as expected. The facilities and quality systems of CMOs
who produce our product candidates and their APIs must pass a pre-approval inspection for compliance with applicable regulations as a condition of FDA approval.
Failure to pass inspections, or to timely remediate any compliance issues identified by the FDA, could substantially delay marketing approval. As long as we are the
product candidate sponsor or the holder of the product approval or manufacturer of record with the FDA or other regulatory authority, we are ultimately responsible for
compliance  with  regulatory  requirements  for  manufacturing  and  distribution  of  our  product  candidates  and  any  future  approved  products,  regardless  of  our  lack  of
control over our third-party manufacturers and suppliers. Failure of those third parties to comply with cGMP and other applicable regulatory requirements may result in
fines and civil penalties on us, suspension of production, delay or failure to obtain product approval, product seizure or recall, or withdrawal of product approval.

70

Our CMOs and component suppliers may experience delays in producing and supplying, or may become unable or unwilling to produce and supply, our clinical
trial  material  or  commercial  supply  material  due  to  financial  or  personnel  constraints,  their  obligations  to,  or  their  decision  to  prioritize  the  production  and  supply  of
products for, other customers, partial or full loss of their facilities, or supply chain disruptions, including as a result of geopolitical conflicts, macroeconomic events or
conditions,  natural  or  man-made  disasters,  or  public  health  emergencies  such  as  the  COVID-19  pandemic.  For  example,  our  single  source  CMO  for  Ovaprene  is
located  in  an  area  of  the  U.S.  that  is  vulnerable  to  tropical  storms,  hurricanes,  flooding  and  tornadoes,  which  have  potential  to  render  its  facilities  inoperative  for
protracted  periods.  One  or  more  of  our  CMOs  may  fail  or  be  unable  to  perform  at  a  time  that  is  costly  or  inconvenient  for  us.  We  may  not  have  adequate  or  any
recourse against a CMO or supplier who does not perform or terminates its agreement with us if such non-performance or termination is excused under the applicable
agreement. We do not have long-term supply agreements with any of our CMOs. We generally enter into manufacturing agreements on a project-by-project basis based
on our development needs, which may heighten the risk of timely availability of sufficient quantities of our product candidates at acceptable costs for clinical trials. As
we advance development of our product candidates, we will need to negotiate agreements for commercial supply and we may not be able to reach agreement on a
timely basis or acceptable terms, or at all. In addition, the FDA or regulatory authorities outside of the U.S. may require that we have an alternate manufacturer of a
product before approving it for marketing and sale in the U.S. or other jurisdiction, and securing such alternate manufacturer before approval of a marketing application
could result in considerable additional time and cost prior to product approval.

Currently, we do not have alternative CMOs or API suppliers to back up our primary vendors of clinical trial material. Identification of and discussions with other
vendors may be protracted and/or unsuccessful, or new vendors may not be successful in producing the same results as our current vendors on a timely basis at the
appropriate  volumes,  at  an  acceptable  cost,  or  at  all.  Therefore,  if  the  current  vendors  become  unable  or  unwilling  to  perform  their  required  activities,  we  could
experience  protracted  delays  or  interruptions  in  the  supply  of  clinical  trial  material  or  any  future  approved  product  for  commercial  sale,  which  could  materially  and
adversely affect our development programs, commercial activities, operating results, and financial condition.

Any new CMO or API supplier would be required to qualify under applicable regulatory requirements. In some cases, the technical skills or technology required
to manufacture our clinical trial material or commercial material may be unique or proprietary to the original CMO or supplier and we may have difficulty, or there may be
contractual  restrictions  prohibiting  us  from,  transferring  such  skills  or  technology  to  another  third  party  and  a  feasible  alternative  may  not  exist.  These  factors  would
increase our reliance on such CMOs and suppliers or require us to obtain a license from them in order to have another third party manufacture our product candidates
or any future approved product. If we are required to change manufacturers for any reason, we will be required to verify that the new manufacturer maintains facilities
and  procedures  that  comply  with  quality  standards  and  with  all  applicable  regulations  and  guidelines.  In  some  cases,  the  FDA  or  a  foreign  regulatory  authority  may
require us to conduct additional clinical or nonclinical studies, collect additional stability data, and provide additional information concerning any new CMO or supplier, or
change in a validated manufacturing process, including scaling-up production, before we could distribute products from that manufacturer or supplier or revised process.
The process of identifying, verifying and transitioning to a new CMO or supplier could significantly delay development or regulatory approval of our product candidates
or delay or disrupt commercialization of any approved product and substantially increase costs or result in significant loss of product sales and associated revenue.

If our CMOs encounter difficulties or otherwise fail to comply with their contractual obligations or there are delays entering commercial supply agreements, we
may  have  insufficient  quantities  of  material  to  support  ongoing  or  planned  clinical  trials  or  to  meet  commercial  demand  for  any  approved  product  in  the  future.  In
addition, any delay or interruption in the supply of materials necessary or useful to manufacture our product candidates could delay the completion of our clinical trials,
increase  the  costs  associated  with  our  development  programs,  and  depending  upon  the  period  of  delay,  require  us  to  terminate  the  clinical  trials  completely  and
commence new clinical trials at significant additional expense. Delays or interruptions in the supply of commercial product could result in increased cost of goods sold
and  lost  sales.  Manufacturing  or  quality  control  problems  may  arise  in  connection  with  the  manufacture  of  our  clinical  trial  material  or  future  approved  product  and
CMOs may not be able to maintain the necessary governmental licenses and approvals to continue their manufacturing services for us. In addition, with respect to any
finished product or key components manufactured outside the U.S., such as the API for Sildenafil Cream, we may experience interruptions in supply due to shipping or
customs difficulties or regional instability. Furthermore, changes in currency fluctuations, shipping costs, or import tariffs could adversely affect cost of goods sold. Any
of the above factors could cause us to delay or suspend anticipated or ongoing clinical trials, regulatory submissions or commercialization of a product candidate, entail
higher costs, or result in being unable to effectively commercialize an approved product. Our dependence on third parties for the manufacture of our product candidates
or future approved products may adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and
competitive basis.

71

Similarly,  while  Organon  now  holds  the  FDA  marketing  approval  and  we  have  transferred  XACIATO  manufacturing  responsibilities  to  Organon,  commercial
production and supply of XACIATO remains subject to comparable manufacturing risks as described herein, and any interruption in the commercial supply of XACIATO
that directly or indirectly results in significant loss of product sales could have a material adverse effect on the payments we receive under our license agreement.

In  some  cases,  we  may  be  contractually  required  to  obtain  clinical  or  commercial  product  supplies  from  specific  third  parties  or  there  may  be  a  limited
number of third-party suppliers of raw materials and other components of our product candidates or future products, which may heighten our dependence
on those third parties and the risk of manufacturing disruptions.

Our agreement with ADVA-Tec restricts our ability to engage a manufacturing source for Ovaprene other than ADVA-Tec during Ovaprene's development period
as well as following regulatory approval, subject to limited exceptions. If ADVA-Tec fails to provide sufficient clinical supply of Ovaprene on anticipated timelines, our
ability  to  complete  clinical  development  and  seek  regulatory  approval  of  Ovaprene  could  be  significantly  delayed.  A  substantial  scale  up  in  production  of  Ovaprene
clinical  supplies  was  necessary  to  support  the  ongoing  Phase  3  clinical  study  of  Ovaprene,  which  took  longer  and  was  more  expensive  than  anticipated,  and  if
Ovaprene receives marketing approval, further substantial manufacturing scale up will be necessary. If Ovaprene receives marketing approval, failure by ADVA-Tec to
provide  sufficient  commercial  product  quantities  at  reasonable  costs  could  have  a  significant  adverse  effect  on  our  revenue  and  ability  to  become  profitable.
Furthermore, for some key raw materials and components of Ovaprene, there currently is only a single source of supply, and alternate sources of supply may not be
readily available.

Under the terms of the SST license agreement, SST was responsible for obtaining supplies of Sildenafil Cream for Phase 2 clinical trials conducted in the U.S.,
and we are responsible for providing supplies of Sildenafil Cream for Phase 3 clinical development and, if approved, for marketing and sale. We do not have any long-
term manufacturing or supply agreements with the CMO from which we plan to obtain Sildenafil Cream for our first Phase 3 clinical study of Sildenafil Cream or with any
supplier of the raw materials required to produce Sildenafil Cream. Future supplies of Sildenafil Cream or the raw materials required to produce Sildenafil Cream may
be more difficult and costly to obtain. For example, the current supplier of sildenafil is located in India. Should this supplier slow production, shut down its factory or
increase its prices for any reason, including due to factors outside of its control such as a public health emergency or geopolitical conflicts or events, we may not be
able to obtain adequate supplies of sildenafil to satisfy our clinical supply requirements.

We rely on, and intend to continue to rely on, third parties for the execution of significant aspects of our product development programs. Failure of these
third parties to successfully carry out their contractual duties, comply with regulatory requirements and applicable law, or meet expected deadlines may
cause significant delays in our development timelines and/or failure of our programs.

Our business model relies on the outsourcing of important product development functions, tests and services to CROs, medical institutions and other specialist
providers,  vendors  and  consultants.  We  rely  on  these  third  parties  to  conduct  our  clinical  trials  and  perform  related  activities,  including  quality  assurance,  clinical
monitoring and clinical data management, as well as to assist us in preparing, submitting and supporting the applications necessary to gain marketing approvals for our
product candidates. For example, we engaged CROs to run all aspects of the pivotal Phase 3 clinical trial of XACIATO, the exploratory Phase 2b RESPOND clinical trial
of Sildenafil Cream, the PCT clinical trial for Ovaprene, and our respective Phase 1/2 clinical studies of DARE-HRT1 and DARE-VVA1. In addition, our ongoing pivotal
Phase 3 clinical trial of Ovaprene is being conducted by third parties under our CRADA with NICHD. We similarly expect to rely on CROs and other third parties to
perform all clinical and nonclinical testing and many other important development and regulatory affairs activities needed to support applications for regulatory approvals
of all product candidates we develop. We do not control these third parties and they may not devote sufficient time and resources to our projects, or their performance
may be substandard, resulting in clinical trial delays or suspensions, delays in submission of our marketing applications or failure of a regulatory authority to accept our
applications  for  filing.  There  is  no  assurance  that  the  third  parties  we  or  our  strategic  collaborators  engage  will  be  able  to  provide  the  functions,  tests,  activities  or
services  as  agreed  upon,  or  provide  them  at  the  agreed  upon  price  and  timeline  or  to  our  requisite  quality  standards,  including  due  to  macroeconomic  factors,
geopolitical conflicts or events, natural or manmade disasters, public health emergencies or pandemics or poor workforce relations or human capital management. We
rely on the efforts of these third parties and if they fail to perform as expected, we could suffer significant delays and additional costs in, and potentially failure of, the
development of one or more of our product candidates.

There is also no assurance these third parties will not make errors in the design, management or retention of our data or data systems. Any failures by such

third parties could lead to a loss of data, which in turn could lead to

72

delays in clinical development and obtaining regulatory approval. Third parties may not pass FDA or other regulatory audits, which could delay or prohibit regulatory
approval. In addition, the cost of such services could significantly increase over time. If these third parties do not successfully carry out their contractual duties or meet
expected deadlines, regulatory approval of current and future product candidates may be delayed, prevented or cost significantly more than expected, all of which could
have a material adverse effect on our business, financial condition, results of operations and prospects.

In  particular,  as  a  result  of  the  CRADA,  we  are  highly  dependent  on  NICHD  and  the  third  parties  it  engages  for  the  conduct  and  completion  of  our  ongoing
pivotal Phase 3 clinical trial of Ovaprene. Pursuant to the terms of the CRADA, the study is being conducted within NICHD’s Contraceptive Clinical Trial Network, or the
CCTN,  with  NICHD's  selected  CRO  providing  clinical  coordination  and  data  collection  and  management  services  for  the  study.  NICHD  is  responsible  for  selecting
participating clinical sites from the pool of CCTN sites and, together with its selected CRO, overseeing the clinical investigators in the conduct of the study, providing
clinical site monitoring and quality assurance along with establishing the electronic data capture database for the study and performing data analysis, which are key
factors to the successful completion of a clinical trial. We do not control these third parties and, accordingly, our control over the conduct and completion of the study is
limited. If NICHD or the third parties it engages for the study prioritize other projects over the study or otherwise do not devote adequate time and resources to the
study, or their performance is substandard, completion of the study may be delayed or suspended or the study may be unsuccessful, which could significantly harm our
business, operating results and financial condition, as well as our relationship with Bayer, and cause the price of our common stock to decline.

Our  ability  to  develop  and  commercialize  our  product  candidates  depends  upon  maintaining  rights  granted  to  us  under  license  agreements  with  third
parties. The loss or impairment of our rights under our in-license agreements relating to XACIATO or our product candidates could have a material adverse
effect on our business prospects, operations and viability.

We have rights to develop and commercialize XACIATO and our product candidates under license agreements between us and third-party licensors. The loss
or impairment of these rights, including as a result of our inability or other failure (or that of our licensors, in the case of sublicenses) to meet our obligations under any
one of such license agreements, including, without limitation, our payment obligations, could have a substantial negative effect on our business and prospects.

In December 2018, we entered into definitive agreements with Hammock Pharmaceuticals, Inc., TriLogic Pharma LLC and MilanaPharm LLC under which we
acquired exclusive global rights to XACIATO for the treatment of bacterial vaginosis, as well as the rights to utilize the underlying proprietary hydrogel drug delivery
technology  for  any  vaginal  or  urological  application  in  humans.  Under  the  license  agreement  with  TriLogic  Pharma  and  MilanaPharm,  we  must  use  commercially
reasonable  efforts  and  resources  consistent  with  those  we  undertake  in  pursuing  development  and  commercialization  of  other  pharmaceutical  products,  taking  into
account program-specific factors, (a) to develop and commercialize at least one licensed product or process in the United States and at least one licensed product or
process in at least one of Canada, the United Kingdom, France, Germany, Italy or Spain, and (b) following the first commercial sale of a licensed product or process in
any jurisdiction, to continue to commercialize that product or process in that jurisdiction. In addition to customary termination rights, MilanaPharm may terminate our
license with respect to a licensed product or process in a country if, after having launched such product or process in such country, we, or our affiliates or sublicensees,
as applicable, discontinue the sale of, or commercially reasonable marketing efforts to sell, such product or process in such country, and fail to resume such efforts or to
reasonably  demonstrate  a  strategic  justification  for  the  discontinuation  and  failure.  See  ITEM  1.  "BUSINESS-Strategic  Agreements  for  Pipeline  Development-
Hammock/MilanaPharm Assignment and License Agreement,” above.

We entered into a license agreement with ADVA-Tec for the exclusive worldwide rights to develop and commercialize Ovaprene that became effective in July
2017.  In  addition  to  standard  termination  rights,  ADVA-Tec  may  terminate  the  license  agreement  if  we  (1)  fail  to  make  significant  scheduled  investments  in  product
development activities over the course of the agreement, (2) fail to commercialize Ovaprene within six months of obtaining a pre-market approval from the FDA, (3) with
respect to the license in any particular country, fail to commercialize Ovaprene in that particular country within three years of the first commercial sale, (4) develop or
commercialize  a  non-hormonal  ring-based  vaginal  contraceptive  device  other  than  Ovaprene,  (5)  fail  to  conduct  certain  clinical  trials,  or  (6)  fail  to  make  certain
milestone, sublicense and/or royalty payments to ADVA-Tec. See ITEM 1. "BUSINESS-Strategic Agreements for Pipeline Development-ADVA-Tec License Agreement,"
above.

In February 2018, we entered into a world-wide license and collaboration agreement with SST for the exclusive worldwide rights to develop and commercialize
Sildenafil Cream for all indications for women related to female sexual dysfunction and/or female reproductive health, including treatment of FSAD. The SST license
agreement provides that each party will have customary rights to terminate the agreement in the event of material

73

uncured breach by the other party and under certain other circumstances. The SST license agreement provides SST with the right to terminate it with respect to the
applicable  SST  licensed  products  in  specified  countries  upon  30  days’  notice  if  we  fail  to  use  commercially  reasonable  efforts  to  perform  development  activities  in
substantial  accordance  with  the  development  plan  contained  in  the  SST  license  agreement,  or  any  updated  development  plan  approved  by  the  joint  development
committee, and do not cure such failure within 60 days of receipt of SST’s notice thereof. See ITEM 1. "BUSINESS-Strategic Agreements for Pipeline Development-
SST License and Collaboration Agreement,” above.

In April 2018, we entered into the Catalent license agreement under which we acquired exclusive global rights to Catalent's IVR technology platform, including
the product candidates we now call DARE-HRT1, DARE-FRT1, and DARE-PTB1. Under this agreement, we must use commercially reasonable efforts to develop and
make  at  least  one  product  or  process  available  to  the  public,  which  efforts  include  achieving  specific  diligence  requirements  by  specific  dates  specified  in  the
agreement, and Catalent may terminate the agreement upon 60 days’ notice for any uncured material breach by us of any of our other obligations under the agreement.
See ITEM 1. "BUSINESS-Strategic Agreements for Pipeline Development-Catalent JNP License Agreement,” above.

If  we  do  not  meet  our  obligations  under  our  license  agreements  in  a  timely  manner,  some  of  which  require  the  expenditure  or  payment  to  the  licensor  of
significant amounts of cash, or if we are unable to obtain an extension of deadlines for satisfying our obligations, we could lose our rights under these agreements.
Moreover, because some of our rights to XACIATO and our product candidates are sublicensed to us, our license agreements may be terminated or we may otherwise
lose rights to intellectual property underlying our product or product candidates in the event of termination or loss of rights by our licensors, which may be outside of our
control. There is no assurance that we would be able to renew or renegotiate license agreements on acceptable terms, or at all, if our existing license agreements (or
the  underlying  agreements  in  the  case  of  sublicenses)  are  terminated.  Furthermore,  we  cannot  guarantee  that  any  license  agreement  will  be  enforceable.  The
termination  of  these  license  agreements  or  our  inability  to  enforce  our  rights  under  these  license  agreements  could  result  in  the  loss  of  our  ability,  or  that  of  our
sublicensees, to develop, manufacture, market or sell XACIATO or the product candidate covered by the agreement, as well as our ability to grant rights to other third
parties  to  collaborate  with  us  in  the  development  and  commercialization  of  our  product  candidates,  which  could  have  a  material  adverse  effect  on  our  business
prospects and operations.

Disputes may arise regarding intellectual property subject to, and any of our rights and obligations under, any license or other strategic agreement, including:

•

•

•

•

•

•

the scope of rights granted under the license agreement and other interpretation-related issues;

the extent to which our technology and processes infringe, misappropriate or violate the intellectual property of the licensor that is not subject to the license
agreement;

our diligence obligations under the license agreement and what activities satisfy those diligence obligations;

the sublicensing of patent and other rights to third parties under any such agreement or collaborative relationships;

the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our
collaborators; and

the priority of invention of patented technology.

In  addition,  the  agreements  under  which  we  license  intellectual  property  or  technology  to  or  from  third  parties  are  complex,  and  certain  provisions  in  such
agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be
the  scope  of  our  rights  to  the  relevant  intellectual  property  or  technology  or  increase  what  we  believe  to  be  our  financial  or  other  obligations  under  the  relevant
agreement, either of which could have a material adverse effect on our business, financial condition, results of operations and prospects. Moreover, if disputes over
intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on commercially acceptable terms, we may be
unable to successfully develop and commercialize, or maintain third-party collaborations to commercialize, the affected product or product candidate.

We  may  seek  to  license  the  product  and  technology  rights  to  additional  product  candidates  in  accordance  with  our  business  strategy,  but  there  can  be  no
assurance we will be able to do so on favorable terms or at all. There are risks, uncertainties and costs associated with identifying, licensing and advancing product
candidates through successful clinical development. Even if we obtained the rights to additional product candidates, there can be no assurance those candidates would
ever be advanced successfully through clinical development.

Risks Related to Commercialization of XACIATO and Our Product Candidates

The commercial success of XACIATO is outside of our control and will depend on Organon’s efforts and capabilities, as well as a variety of factors, many of
which currently are unknown or uncertain, and if commercialization of XACIATO is not successful, our business and prospects may suffer.

If commercialization of XACIATO is not successful, or is perceived to be unsuccessful, our business, financial condition, results of operations and prospects
may suffer, particularly because XACIATO is the first and only product for which we have received regulatory approval. XACIATO’s commercial success will depend on
many factors, including:

the capabilities of Organon and its commitment of sufficient resources to market, distribute and sell the product;

timely and adequate commercial supply of the finished product and its components;
perceived superiority of its cure rates compared to other available treatments;
the extent to which the approved product labeling contains features or expected benefits that differentiate it from other available treatments;
preferences by health care providers and women for a vaginally administered therapy;
the prevalence and severity of any adverse side effects;
patient satisfaction and willingness to use it again and refer it to others;

•
•
•
•
•
•
•
•
•
•
•
• market exclusivity provided by our intellectual property rights or conferred by regulatory authorities; and
•

price pressure given the high level of generic treatments and changes in health care laws and regulations, including the Inflation Reduction Act of 2022;
adequate coverage, pricing and reimbursement from third-party payors;
the willingness of patients, without third-party insurance coverage or adequate reimbursement, to pay for the product;
the success or failure of other branded therapies;

approval of new entrants, including alternative, non-antibiotic treatment options.

There is no assurance that Organon’s efforts with respect to XACIATO will be successful or that product sales will be able to generate revenue to us at the
levels or within the timing we expect or at the levels or within the timing necessary to support our goals. See also the risks and uncertainties described under “Risks
Related to Our Dependence on Third Parties,” above.

We have no internal sales, marketing or distribution capabilities. If we are unable to establish those capabilities on our own or through third parties, we will
be unable to successfully commercialize our product candidates, if approved, or generate product sales revenue.

We do not have a product marketing, sales or distribution infrastructure. In order to commercialize any of our product candidates if approved for commercial
sale, we must either establish a sales and marketing organization with technical expertise and supporting distribution capabilities or collaborate with third-parties that
have sales and marketing experience. As we move our product candidates through development toward, and in some cases, through regulatory approval, we evaluate
several  options  for  each  product  candidate's  commercialization  strategy.  These  options  include  building  our  own  sales  force  and  other  commercial  infrastructure,
entering  into  strategic  marketing  partnerships  with  third  parties,  including  commercial  sales  organizations  or  other  pharmaceutical  or  biotechnology  companies,  out-
licensing the product to other pharmaceutical or biotechnology companies, and combinations of these strategies. We currently have no commercialization agreements
with  third  parties  other  than  our  license  agreements  with  Organon  for  XACIATO  and  Bayer  for  Ovaprene.  We  may  not  be  able  to  maintain  our  existing  commercial
collaborations or establish and maintain other commercial collaborations on favorable terms, on a timely basis, or at all.

To generate revenue from our product candidates, if approved, we may need to establish a commercial infrastructure. There are significant risks involved with
establishing our own commercial infrastructure. For example, recruiting and training a sales force is expensive and time-consuming and could delay product launch. If
we recruit and train a sales force and the commercial launch of the product is delayed or does not occur for any reason, we would have prematurely or unnecessarily
incurred  significant  commercialization  expenses.  This  may  be  costly,  and  our  investment  would  be  lost  if  we  could  not  retain  or  reposition  our  sales  and  marketing
personnel. Both the launch and ongoing commercial support of our products would require significant capital, which may not be available to us

75

when  needed  or  on  acceptable  terms  or  at  all.  All  of  these  factors  could  strain  our  cash  resources  and  require  us  to  raise  additional  capital.  In  addition,  there  is  no
guarantee that our efforts to generate product revenue would be successful.

Factors that may hinder efforts to commercialize our products on our own include:

•

•

•

•

our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel;

the inability of sales personnel to obtain access to physicians or educate an adequate number of physicians as to the benefits of our products;

the lack of complementary products our sales personnel could offer, which may put us at a competitive disadvantage compared to companies with more
extensive product lines; and

unforeseen costs and expenses associated with creating an independent sales and marketing organization.

The risks described above may also apply if our commercial collaborations do not involve an exclusive license of substantially all commercialization rights to a

third party and we instead enter into co-promotion arrangements with a third party.

Failure to timely enter into or maintain a commercialization arrangement with a third party or establish our own commercialization capabilities could significantly
delay commercial launch of our products or require us to reduce the scope of any sales and marketing activities, which could have a material adverse effect on our
business, financial condition and results of operations.

Our product candidates, if approved, and XACIATO will face intense competition and our business and operating results will suffer if we, or our commercial
collaborators, fail to compete effectively.

The  biopharmaceutical  industry  is  intensely  competitive  and  characterized  by  rapid  technological  developments.  Our  competitors  and  potential  competitors
include large, well-established pharmaceutical and biotechnology companies, many of which have robust product portfolios and strong franchises in women’s health.
Many of our competitors or potential competitors, either alone or with strategic collaborators, have:

• much greater financial, research, technical and human resources than we have at every stage of the product development and commercialization life cycle;

• more extensive experience in designing and conducting clinical trials, nonclinical studies, obtaining regulatory approvals, and in manufacturing, marketing

and selling prescription medical products; and

•

approved products or product candidates in late stages of development for one or more of our target indications.

Competitive products may be equally safe and as effective as our products, but sold at a substantially lower price. Alternatively, competitive products may be

safer or more effective, more convenient to use, have better insurance coverage or reimbursement levels or be more effectively marketed and sold than our products.

Our  product  candidates,  if  approved,  will  compete  with  products  that  have  already  been  accepted  by  the  medical  community  and  patients.  If  our  product
candidates fail to generate compelling clinical results or if patients and health care providers fail to adopt our products for their respective indications, their commercial
potential  could  be  adversely  impacted  or  severely  diminished.  It  is  possible  that  the  potential  advantages  of  our  product  candidates  do  not  materialize  or  that  the
approved prescribing information for our products does not describe expected features or benefits. We also expect to face competition from new products that enter the
market  over  time.  We  are  aware  of  products  currently  under  development  intended  for  the  same  indications  as  our  product  candidates.  These  competitive  product
candidates  may  prove  safer,  more  tolerable,  more  effective,  and  less  expensive,  and  may  be  introduced  to  market  earlier,  or  produced,  marketed  and  sold  more
effectively or on a more cost-effective basis, than our product candidates. The success of competitive products may render our product candidates noncompetitive or
obsolete, even prior to completion of their development.

With respect to XACIATO, there are many FDA-approved products for treating bacterial vaginosis, and many are generic. XACIATO will compete with those
products. Current therapies for the treatment of bacterial vaginosis primarily consist of oral and vaginal formulations of antibiotics delivered as a single dose or through
multiple  doses  over  consecutive  days.  If  health  care  providers  do  not  view  the  prescribing  information  for  XACIATO  as  compelling  compared  with  other  products
available  for  the  treatment  of  bacterial  vaginosis,  or  if  competitive  products  have  better  insurance  coverage  or  reimbursement  levels  than  XACIATO,  health  care
providers  may  opt  to  continue  to  prescribe  existing  treatments  rather  than  recommend  or  prescribe  XACIATO  to  their  patients.  In  addition,  women  may  prefer  orally
delivered options to vaginally administered XACIATO unless they view XACIATO as providing significantly

76

superior efficacy, safety and/or convenience. Failure of our commercial collaborator to generate significant net sales of XACIATO would negatively effect the payments
we receive under our license agreement.

The women's health market includes many generic products and growth in generics is expected to continue, which could make the successful introduction
of our branded products difficult and expensive.

The  proportion  of  the  U.S.  market  made  up  of  generic  products  has  been  increasing.  If  this  trend  continues,  it  may  be  more  difficult  for  us  or  a  commercial
collaborator to introduce a new branded medical product, if approved, at a price that will allow us to achieve acceptable levels of revenue and net income from product
sales. Generic competition is particularly strong in contraception and hormone therapy, which are areas in which our product candidates, if approved, will compete. In
order for our branded products to develop commercial markets and for third-party payors to cover these higher cost products, our products must demonstrate better
patient compliance and clinical benefit in their clinical trials compared to other available products.

Additional marketing and educational efforts may be required to introduce a new branded prescription medical product in order to overcome the trend towards
generics and gain access to reimbursement by payors. If we or a commercial collaborator cannot introduce a product at the desired price or gain reimbursement from
payors for the product, or if patients opt for a lower cost generic product rather than pay out-of-pocket or a higher co-pay for our product, our revenues or royalties and
other license fees, as applicable, will be limited.

XACIATO and any of our future approved products may fail to achieve the degree of market acceptance by physicians, patients, third-party payors or others
in the medical community necessary for commercial success, which would negatively impact our business.

XACIATO and any future products may fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community.
If XACIATO and any future products do not achieve an adequate level of market acceptance, they may not generate significant net product revenue or net sales or
result in significant payments to us from our commercial collaborators, we may suffer reputational harm and we may never become profitable. The degree of market
acceptance of XACIATO and any future products will depend on several factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the timing of our receipt of any marketing approvals and the jurisdictions in which marketing approvals are obtained;

the terms of any approvals, such as any restrictions on the use of our product together with other medications;

the indications for which the product is approved;

demonstrated evidence of efficacy and safety;

the approval and availability of alternative treatments and products for the same indications as our product;

the prevalence and severity of any adverse side effects associated with our product;

convenience  and  ease  of  administration  for  patients  compared  to  alternative  treatments  and  products,  or  other  potential  advantages  and  disadvantages
compared to the alternatives;

adverse publicity about our product or favorable publicity about competing products;

our ability to offer our product for sale at competitive prices;

the willingness of the target patient population to try a new product and of physicians to prescribe a new product;

the success of any physician education programs for our product;

the availability and extent of third-party coverage and reimbursement for our product and amount of out-of-pocket cost to patients;

the willingness of uninsured patients to pay for the product;

the willingness of pharmacy chains to stock the product; and

effectiveness of our or our collaborators’ sales and marketing strategy and efforts.

If  XACIATO  or  any  future  product  does  not  achieve  an  adequate  level  of  market  acceptance,  it  could  have  a  material  and  adverse  effect  on  our  business,

financial condition, results of operation and prospects.

The  commercial  success  of  Ovaprene,  if  approved,  will  depend  on  market  acceptance  of  a  hormone-free,  monthly  intravaginal  product,  availability  and
effectiveness of alternative contraceptive products and women's preferences, as well as the success of Bayer’s marketing and sales efforts.

77

Today, there are a variety of hormonal and non-hormonal contraceptive options available to women, including oral contraceptive pills and intrauterine devices,
newer hormonal contraceptive products including implants, injectables, vaginal rings, patches, and hormonal intrauterine systems, and non-hormonal methods such as
female  condoms,  novel  diaphragms,  and  new  methods  of  female  sterilization.  In  surveys,  women  have  said  that  the  features  they  consider  most  important  when
selecting a contraceptive method are efficacy, ease-of-use and side effects. To have significant revenue potential as a new contraceptive product option, Ovaprene may
need  to  have  a  typical  use  efficacy  outcome  (which  is  the  expected  rate  of  pregnancy  protection  once  the  product  is  used  widely  under  everyday  circumstances)
comparable to current non-implanted hormonal contraceptive methods (pills, patches and vaginal rings), which is approximately 86%-91% typical use efficacy. Clinical
testing will also need to demonstrate that the product can be safely worn for multiple weeks.

If we receive regulatory approval to market Ovaprene, its commercial success, or the success of any other future contraceptive product candidate we may seek
to  develop,  including  our  current  pre-clinical  stage  candidates,  will  depend  upon  the  contraceptive  market  and  market  acceptance  of  an  alternative  method.  Risks
related to market acceptance include:

• minimum acceptable contraceptive efficacy rates;

•

•

•

•

•

perceived safety differences of hormonal and/or non-hormonal contraceptive options;

competition from new lower dose hormonal contraceptives with more favorable side effect profiles;

new generic contraceptive options including a generic version of the hormone-containing intravaginal product NuvaRing®;

the effects of changes in health care laws and regulations on third-party payor coverage (including the birth control coverage mandate) and reimbursement
and out-of-pocket costs to patients; and

the availability and extent of third-party coverage and reimbursement for our product, the amount of out-of-pocket cost to patients and the effects of any
changes in health care laws and regulations, including the birth control mandate, on product pricing and coverage and out-of-pocket costs to patients.

If one or more of these risks occur, it could reduce the market potential for Ovaprene, or any future contraceptive product we may seek to develop, and place

pressure on our business, financial condition, results of operations and prospects.

Under our license agreement with Bayer, provided the license grant becomes effective, Bayer will have exclusive rights to market and sell Ovaprene in the U.S.
Accordingly, the potential value of Ovaprene to our company is highly dependent on the efforts and activities of Bayer. Should Ovaprene fail to generate compelling
clinical safety and efficacy data, the license grant under our agreement with Bayer may never become effective. Even if Bayer elects to make the license agreement
effective, Bayer has significant discretion in determining the resources that it will allocate to commercialization of Ovaprene and Ovaprene’s commercial success may
be limited, in which case our business, financial condition, results of operations and prospects could suffer significantly.

The commercial success of Sildenafil Cream, if approved, will depend on the availability of alternative products for female sexual dysfunction disorders, the
age group for which our product is indicated and women's preferences, in addition to the market's acceptance of our topical cream.

Today, there are no FDA-approved products to treat FSAD. While our goal is for Sildenafil Cream to be the first product to receive such approval, one or more
competitive products may be approved before our product. Even if we achieve our goal of being first-to-market for FSAD, the costs associated with introducing a new
product into the sexual dysfunctions market would likely be significant, and regardless of the amount spent, there is no guarantee that our new product will be broadly
adopted.  Women  may  be  hesitant  to  use  Sildenafil  Cream  for  many  reasons,  including  the  lack  of  experience  with  any  product  designed  to  treat  FSAD,  the  lack  or
perceived lack of clinical evidence supporting its benefits, and the out-of-pocket cost of Sildenafil Cream, particularly if it is not covered by insurance.

In addition, FSAD is a condition that impacts women of many ages, including older and elderly populations. We have not yet thoroughly studied the topical or
clinical  pharmacology  of  Sildenafil  Cream  in  different  patient  populations,  and  sildenafil,  the  active  ingredient  in  our  drug  candidate,  has  not  been  tested  over  long
periods of time in older or elderly women. Older or elderly women may react differently and adversely to Sildenafil Cream than younger populations. Based on our end-
of-Phase  2  meeting  with  the  FDA,  we  expect  our  pivotal  Phase  3  clinical  trials  of  Sildenafil  Cream  will  be  conducted  in  a  premenopausal  population.  Therefore,  we
expect  initial  FDA  approval  of  Sildenafil  Cream,  if  received,  would  be  limited  to  premenopausal  women.  Should  Sildenafil  Cream  not  be  studied  in  older  or  elderly
women, or, if studied in those populations, should it show increased risk of adverse reactions, or signs thereof, in older or elderly women during clinical development,
the potential market for Sildenafil Cream could be significantly limited, which could have a material adverse impact on the value of this program.

78

If we receive marketing approval in the future, our commercial success with Sildenafil Cream will depend, in large part, on the ability of the product candidate to
demonstrate safety and effectiveness in treating FSAD in clinical trials, as well as our ability, or that of a commercial collaborator, to educate doctors and women about
the need to diagnose and treat FSAD and the potential benefits of using of Sildenafil Cream, which may not prove successful. Sexual arousal can be influenced by
many emotional and physiological factors. To be successful, our clinical trials of Sildenafil Cream must anticipate such factors. Sildenafil Cream is designed to increase
local blood flow to the genital tissue. Even if Sildenafil Cream demonstrates success in increasing blood flow, the product candidate may not demonstrate a significant,
or any, increase in arousal or improvement in the overall sexual experience in some women in our clinical trials. If we fail to generate compelling clinical results, we may
not  receive  regulatory  approval  to  market  Sildenafil  Cream,  or,  if  approved,  many  physicians  may  not  prescribe  and/or  many  women  diagnosed  with  sexual  arousal
disorder may opt not to try Sildenafil Cream. If we fail to produce strong clinical outcomes, our ability to build a commercial market for Sildenafil Cream will be materially
adversely impacted.

The  commercial  success  of  DARE-HRT1,  if  approved,  will  depend  on  the  availability  of  alternative  products  for  managing  the  vasomotor  and  vaginal
symptoms of menopause and women's preferences, in addition to the market's acceptance of our IVR.

Treatments  to  address  the  symptoms  associated  with  menopause,  including  the  vasomotor  symptoms,  also  known  as  hot  flashes,  include  combinations  of
prescription  hormones,  some  of  which  are  FDA-approved  and  others  which  are  prepared  in  compounding  pharmacies.  Numerous  products  already  exist,  and  this
number  is  likely  to  expand  with  time.  In  addition,  there  has  been  an  emerging  preference  among  some  women  and  providers  for  bio-identical  hormones  that  are
chemically  identical  to  those  the  body  produces.  DARE-HRT1  is  designed  to  offer  a  convenient  vaginal  ring  that  continuously  delivers  a  combination  of  bio-identical
estradiol  and  progesterone  over  28  days.  Until  relatively  recently,  no  FDA-approved  bio-identical  hormone  treatments  existed.  In  2018,  Bijuva®  estradiol  and
progesterone capsules, which are to be taken daily, received the first such approval. Studies have failed to demonstrate that bio-identical hormones are safer than other
hormones, so DARE-HRT1 will need to compete with many types of hormone therapy options in terms of convenience, safety and efficacy in managing symptoms of
menopause.

Risks related to market acceptance of DARE-HRT1, if approved for hormone therapy, include:

•

•

•

•

•

•

•

•

preference for a vaginal ring delivery of hormone therapy over pills, patches and creams by menopausal women;

data regarding symptom relief of DARE-HRT1 over other hormonal treatments for vasomotor symptoms associated with menopause;

preference for bio-identical hormones by women and health care providers;

positive or negative news and research regarding bio-identicals;

preference for an FDA-approved product by women and health care providers over treatments prepared in compounding pharmacies;

the success or failure of Bijuva®, the first FDA-approved bio-identical product;

new information supportive or against the use of hormones in menopause; and

availability and extent of third-party payor coverage and reimbursement for DARE-HRT1 and out-of-pocket cost for patients.

Depending  upon  the  direction  of  the  factors  above,  a  commercial  market  for  DARE-HRT1  may  develop  more  slowly  than  expected,  or  not  at  all,  and  our

business, financial condition, results of operation and prospects could be hurt as a result.

The  FDA  and  other  regulatory  agencies  actively  enforce  the  laws  and  regulations  prohibiting  the  promotion  of  off-label  uses  for  prescription  medical
products.  If  we  or  any  commercial  collaborator  is  found  or  alleged  to  have  improperly  promoted  any  of  our  products  for  off-label  uses,  we  may  become
subject to significant liability, including fines, penalties or injunctions, and reputational harm.

The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription medical products. In particular, a product
may not be promoted for uses that are not approved by the FDA (i.e., off-label uses), as reflected in the product’s approved or cleared labeling. Promotional labeling
and advertising for any of our drug product candidates that receive marketing approval, must be submitted to FDA at the time of first use and the agency actively solicits
reports from health care professionals about improper promotional claims or activities by the drug manufacturer or distributor. Medical device promotion and advertising
are subject to similar off-label restrictions, although without the same requirement to submit promotional materials to FDA at the time of first

79

use. Both prescription drug and medical device promotional materials must present a fair balance between the product’s effectiveness and the risks associated with its
use, and must be truthful and not misleading.

If  we  or  a  commercial  collaborator  is  alleged  or  found  to  have  promoted  a  product  for  any  off-label  use,  we  may  become  subject  to  significant  liability  and
reputational harm. The federal government has levied large civil and criminal fines against companies for alleged improper medical product promotion and has enjoined
several companies from engaging in off-label promotion. The FDA has also requested that companies enter into consent decrees or permanent injunctions under which
specified  promotional  conduct  is  changed  or  curtailed.  Other  enforcement  authorities  may  also  take  action  against  a  company  for  promoting  an  off-label  use  of  a
prescription medical product, which could result in penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. See also “Risks
Related to Our Business Operations and Industry- The pharmaceutical and medical device industries are highly regulated and subject to various fraud and abuse laws,
including, without limitation, the U.S. federal Anti-Kickback Statute, the U.S. federal False Claims Act and the U.S. Foreign Corrupt Practices Act” below.

If we or our commercial collaborators, as applicable, cannot successfully manage the product promotion to ensure compliance with these legal and regulatory

requirements, we could become subject to significant liability, our reputation could be damaged, and adoption of our products could be considerably impaired.

Unexpected safety, efficacy or quality concerns relating to XACIATO could develop, which could have significant negative consequences for us.

XACIATO was approved by the FDA based on prior findings of safety or effectiveness of previously approved clindamycin products and on clinical data from the
Phase  3  DARE-BVFREE  clinical  trial,  in  which  307  patients  were  randomized  and  treated  once.  In  light  of  its  commercial  launch,  XACIATO  will  be  used  by  larger
numbers of patients, and some patients may use multiple regimens over the course of a year. New data may emerge from market surveillance or future clinical trials of
XACIATO that give rise to safety, efficacy or quality concerns and result in negative consequences, including:

restrictions on the promotion or marketing of the product;
issuance of “Dear Doctor Letters” or similar communications to health care professionals or the public regarding safety or efficacy concerns;

• modification to the product’s prescribing information, such as the addition of boxed or other warnings, contraindications, or limitations of use;
•
•
•
•

imposition of post-marketing clinical trial requirements or other post-marketing studies;
product distribution restrictions or other risk management measures, such as a risk evaluation and mitigation strategy, or REMS, which could include elements
to assure safe use;
• warning or untitled letters;
•
•
•
•

suspension or withdrawal of marketing approvals;
suspension or termination of ongoing clinical trials, if any;
refusal by regulators to approve pending marketing applications or supplements to approved applications that we submit;

suspension of, or imposition of restrictions on, the operations of our commercial collaborator or any CMO producing commercial supplies of XACIATO, including
costly new manufacturing requirements;
costly and time-consuming corrective actions;
voluntary or mandatory product recalls or withdrawals from the market;
significant reputational harm; and
product liability claims and lawsuits.

•
•
•
•

Furthermore,  the  discovery  of  significant  problems  with  another  intravaginally  administered  or  clindamycin-containing  product  perceived  as  comparable  to
XACIATO, could have an adverse impact on commercialization of XACIATO, including as a result of occurrence of the events described above. For example, XACIATO
has not been studied in pregnant or breastfeeding women. Should increased risk of miscarriage or other adverse effects on maternal or fetal outcomes or breastfed
infants be observed in future data from market surveillance or clinical trials of XACIATO or other clindamycin products, XACIATO’s commercial potential may be limited
and we could become subject to product liability claims and lawsuits.

80

The  occurrence  of  any  of  the  circumstances  described  above  could  reduce  XACIATO’s  market  acceptance,  inhibit  or  delay  its  commercialization  within  or
outside  of  the  U.S.  and  adversely  affect  sales  of  XACIATO,  which  could,  in  turn,  have  a  significant  negative  impact  on  the  payments  we  receive  under  our  license
agreement with our commercial collaborator for XACIATO, as well as our stock price.

If we suffer negative publicity concerning the safety or efficacy of XACIATO or the product candidates we develop, our reputation could be harmed, product
sales could be adversely affected or we may be forced to cease or curtail product development efforts.

If concerns should arise about the actual or anticipated clinical outcomes regarding the safety of XACIATO or any of our product candidates, including as a
result of safety concerns related to third-party products containing the same or similar active or excipient substances, such concerns could adversely affect the market’s
perception  of  XACIATO  and  our  product  candidates.  Negative  publicity  could  be  time  consuming  and  expensive  to  address  and  could  adversely  affect  potential
opportunities with strategic partners or collaborators, lead to a decline in product sales, and negatively impact investor sentiment toward a product or product candidate
or our company as a whole, which could lead to a decline in the price of our common stock.

We are and will remain subject to ongoing regulatory requirements even after obtaining regulatory approval for a product candidate.

Even if any of the product candidates we develop are approved by the FDA or a comparable regulatory authority outside of the U.S., as long as we are the
holder of the product approval or manufacturer of record with the FDA or other regulatory authority, we will be subject to ongoing regulatory requirements with respect to
manufacturing,  labeling,  packaging,  storage,  advertising,  promotion,  sampling,  record-keeping,  conduct  of  post-marketing  clinical  trials  and  submission  of  safety,
efficacy and other post-approval information, including both federal and state requirements in the U.S. and requirements of comparable foreign regulatory authorities.

In addition, manufacturers and manufacturers’ facilities are required to continuously comply with FDA and comparable foreign regulatory authority requirements,
including  ensuring  quality  control  and  manufacturing  procedures  conform  to  cGMP  regulations  and  corresponding  foreign  regulatory  manufacturing  requirements.
Accordingly, we and our contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments
made in our NDA or PMA submissions to the FDA.

Any marketing approvals we receive for our product candidates in the future may be subject to limitations on the approved indicated uses for which the product
may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials, and surveillance
to monitor the safety and efficacy of the product. In addition, we will be required to report adverse reactions and production problems, if any, to the FDA and comparable
foreign  regulatory  authorities  (when  products  are  approved  in  foreign  markets).  Any  new  legislation  addressing  drug  safety  issues  could  result  in  delays  in  product
development or commercialization, or increased costs to assure compliance.

If  a  regulatory  agency  discovers  previously  unknown  problems  with  a  product,  such  as  problems  with  the  facility  where  the  product  is  manufactured,  or  it
disagrees with the promotion, marketing or labeling of a product, the regulatory agency may impose restrictions on that product or on us or our commercial collaborator,
including requiring withdrawal of the product from the market. If we or our commercial collaborators are unable to comply with applicable regulatory requirements, a
regulatory agency or enforcement authority may, among other things:

•

•

•

•

•

•

•

issue warning letters;

impose civil or criminal penalties;

suspend or withdraw regulatory approval;

suspend any of our ongoing clinical trials;

refuse to approve pending applications or supplements to approved applications submitted by us;

impose restrictions on our operations, including closing our contract manufacturers’ facilities; or

require a product recall.

Any  government  investigation  of  alleged  violations  of  law  would  require  us  and/or  our  commercial  collaborators  to  expend  significant  time  and  resources  in
response and could generate adverse publicity. Any inability to comply with ongoing regulatory requirements may significantly and adversely affect our ability, or that of
our collaborators, to develop and commercialize our products and the value of our business, and our operating results would be adversely affected.

81

Failure to successfully obtain coverage and reimbursement for XACIATO and any future products in the United States, or the availability of coverage only at
limited levels, would diminish our ability, or that of a commercial collaborator, to generate net product revenue or net sales.

Coverage from government health care programs and private commercial health insurance companies is critical to the commercial success of XACIATO and
any future products. Market acceptance and sales of XACIATO and any future products that we or a commercial collaborator may seek to commercialize will depend in
part on the extent to which reimbursement for these products will be available from third-party payors. Third-party payors, such as government health care programs,
private  health  insurers,  managed  health  care  providers,  and  other  organizations,  are  increasingly  challenging  medical  product  prices  and  examining  the  medical
necessity and cost-effectiveness of medical products, in addition to their safety and efficacy. If these third-party payors do not consider XACIATO or any future product
to be cost-effective compared to other available therapies and medical products, they may not cover the product as a benefit under their plans or, even if they do, the
level of payment may not be sufficient to allow us, or a commercial collaborator, to sell the product on a profitable basis. Coverage decisions can depend upon clinical
and  economic  standards  that  disfavor  new  prescription  medical  products  when  more  established  or  lower  cost  alternatives  are  already  available  or  subsequently
become  available.  Third-party  payor  coverage  may  not  be  available  to  patients  for  XACIATO  or  any  future  product.  If  third-party  payors  do  not  provide  adequate
coverage and reimbursement, health care providers may not prescribe our products or patients may ask their health care providers to prescribe competing products
with more favorable reimbursement.

Significant uncertainty exists as to the reimbursement status for newly approved prescription medical products, including coverage and payment. There is no
uniform  policy  requirement  for  coverage  and  reimbursement  for  prescription  medical  products  among  third-party  payors  in  the  U.S.;  therefore,  coverage  and
reimbursement for our products could differ significantly from payor to payor. In the U.S., the principal decisions about reimbursement for new medical products are
typically made by the Centers for Medicare and Medicaid Services, or CMS, as CMS decides whether and to what extent a new medical product will be covered and
reimbursed  under  Medicare.  Third-party  payors  often  rely  upon  Medicare  coverage  policy  and  payment  limitations  to  a  substantial  degree  in  setting  their  own
reimbursement policies, but they also have their own methods and approval process apart from Medicare coverage and reimbursement determinations. It is difficult to
predict what CMS will decide with respect to reimbursement. Decisions regarding the extent of coverage and amount of reimbursement to be provided for XACIATO and
any future products will be made on a payor-by-payor basis. Accordingly, one third-party payor’s determination to provide coverage for a product does not assure that
other payors will also provide coverage and adequate reimbursement for the product. Moreover, reimbursement agencies in Europe may be more conservative than
CMS, should XACIATO or any of our product candidates be approved for marketing in Europe.

In  addition  to  CMS  and  private  payors,  professional  organizations  can  influence  decisions  about  reimbursement  for  new  medical  products  by  determining
standards of care. In addition, many private payors contract with commercial vendors who sell software that provides guidelines that attempt to limit utilization of, and
therefore reimbursement for, certain products deemed to provide limited benefit as compared to existing alternatives. Such organizations may set guidelines that limit
reimbursement or utilization of any of our commercialized products.

To  secure  coverage  and  reimbursement  for  XACIATO  and  any  future  product,  we  or  a  commercial  collaborator  may  need  to  conduct  expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product to third-party payors, which costs would be in addition
to  those  required  to  obtain  FDA  or  other  comparable  regulatory  approvals.  A  payor’s  decision  to  provide  coverage  for  a  product  does  not  imply  that  an  adequate
reimbursement  rate  will  be  approved.  Managed  care  organizations  and  other  private  insurers  frequently  adopt  their  own  payment  or  reimbursement  reductions.
Consolidation among managed care organizations has increased the negotiating power of these entities. Third-party payors increasingly employ formularies to control
costs  by  negotiating  discounted  prices  in  exchange  for  formulary  inclusion.  Failure  to  obtain  timely  or  adequate  pricing  or  formulary  placement  for  XACIATO  or  any
future  product,  or  obtaining  such  pricing  or  placement  at  unfavorable  pricing  levels,  could  materially  adversely  affect  our  business,  financial  conditions,  results  of
operations and prospects. Moreover, eligibility for reimbursement does not imply that any product will be paid for in all cases or at a rate that covers our costs, or those
of a commercial collaborator. Interim payments for new products, if applicable, also may not be sufficient to cover our costs, or those of a commercial collaborator, and
may  not  be  made  permanent.  Payment  rates  may  vary  according  to  the  use  of  the  product  and  the  clinical  setting  in  which  it  is  used,  may  be  based  on  payments
allowed for lower cost products that are already reimbursed and may be incorporated into existing payments for other services. Net prices for products may be reduced
by mandatory discounts or rebates required by third-party payors and by any future relaxation of laws that presently restrict imports of products from countries where
they may be sold at lower prices than in the U.S.

Accordingly, the coverage determination process is often a time-consuming and costly process that will require us or our commercial collaborator to provide

scientific and clinical support for the use of our products to each

82

payor separately, with no assurance that coverage and adequate payment will be applied consistently or obtained. The process for determining whether a payor will
cover and how much it will reimburse a product may be separate from the process of seeking approval of the product or for setting the price of the product. Even if
reimbursement is provided, market acceptance of our products may be adversely affected if the amount of payment for our products proves to be cost prohibitive for
health care providers or their patients, or less profitable than alternative treatments or products, or if administrative burdens make our products less desirable to use.
Our inability, or that of our commercial collaborator, to obtain coverage and profitable payment rates from both government-funded and private payors for XACIATO or
any future product could have a material adverse effect on our operating results, our ability to raise capital needed to execute our business strategy and our overall
financial condition.

Failure  by  us  or  a  commercial  collaborator  to  obtain  timely  and  adequate  coverage  and  pricing  for  XACIATO  and  any  future  products,  or  obtaining  such

coverage and pricing at unfavorable levels, could materially adversely affect our business, financial condition, results of operations and prospects.

Legislation and legislative and regulatory proposals intended to contain health care costs may adversely affect our business.

The containment of health care costs has become a priority of federal and state governments and the prices of drug products have been a focus of this effort.
For example, there have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing,
review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. We expect that
federal, state and local governments in the U.S. will continue to consider legislation directed at lowering the total cost of health care and prescription drugs. Individual
states  in  the  U.S.  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  product  pricing,  including  price  or  patient
reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed
to encourage importation from other countries and bulk purchasing. In December 2020, the U.S. Supreme Court held unanimously that federal law does not preempt
the states’ ability to regulate pharmaceutical benefit managers and other members of the health care and pharmaceutical supply chain, an important decision that may
lead to further and more aggressive efforts by states in this area.

The Biden Administration has also indicated that lowering prescription drug prices is a priority, and on August 16, 2022, President Biden signed into the law the
Inflation Reduction Act of 2022, or the IRA. Among other things, the IRA has multiple provisions that may impact the prices of drug products that are both sold into the
Medicare program and throughout the U.S. Starting in 2023, a manufacturer of drugs or biological products covered by Medicare Parts B or D must pay a rebate to the
federal government if their drug product’s price increases faster than the rate of inflation. This calculation is made on a drug product by drug product basis and the
amount  of  the  rebate  owed  to  the  federal  government  is  directly  dependent  on  the  volume  of  a  drug  product  that  is  paid  for  by  Medicare  Parts  B  or  D.  Additionally,
starting for payment year 2026, the Centers for Medicare and Medicaid Services, or CMS, will negotiate drug prices annually for a select number of single source Part D
drugs without generic or biosimilar competition. CMS will also negotiate drug prices for a select number of Part B drugs starting for payment year 2028. If a drug product
is selected by CMS for negotiation, it is expected that the revenue generated from such drug will decrease. CMS has begun to implement these new authorities and
entered  into  the  first  set  of  agreements  with  pharmaceutical  manufacturers  to  conduct  price  negotiations  in  October  2023.  However,  the  IRA's  impact  on  the
pharmaceutical  industry  in  the  U.S.  remains  uncertain,  in  part  because  multiple  large  pharmaceutical  companies  and  other  stakeholders  (e.g.,  the  U.S.  Chamber  of
Commerce) have initiated federal lawsuits against CMS arguing the program is unconstitutional for a variety of reasons, among other complaints. Those lawsuits are
currently ongoing. Further, in December 2023, the Biden Administration announced an initiative to control the price of prescription drugs through the use of march-in
rights  under  the  Bayh-Dole  Act  of  1980  (the  "Bayh-Dole  Act"),  and  the  National  Institute  of  Standards  and  Technology  published  for  comment  a  Draft  Interagency
Guidance Framework for Considering the Exercise of March-In Rights, which for the first time includes the price of a product as one factor an agency can use when
deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.

It is uncertain whether and how future legislation or regulatory changes could affect prospects for XACIATO or our product candidates or what actions third-
party payors may take in response to any such health care reform proposals or legislation. Adoption of price controls and cost-containment measures, and adoption of
more  restrictive  policies  in  jurisdictions  with  existing  controls  and  measures  reforms,  may  prevent  or  limit  our  ability,  or  the  ability  of  a  commercial  collaborator,  to
commercialize any future products as well as our ability to generate revenue and attain profitability.

83

Even  seemingly  small  copayments  or  other  cost-sharing  requirements  could  dramatically  reduce  the  market  potential  for  XACIATO  and  our  product
candidates.

If the out-of-pocket costs for XACIATO or any of our product candidates, if approved, are deemed by women to be unaffordable, or if less expensive alternatives
exist, a commercial market may never develop or the market potential for that product may be significantly reduced, which could have a material adverse effect on our
business, financial condition, and prospects.

With  regard  to  contraceptive  products,  the  ACA  and  subsequent  regulations  enacted  by  DHHS,  require  health  plans  to  provide  coverage  for  women’s
preventive care, including all forms of FDA-cleared or approved contraception, without imposing any cost sharing on the plan beneficiary. These regulations ensure that
women in the U.S. who wish to use an approved form of contraception may request it from their doctors and their health insurance plan must cover all costs associated
with such contraceptive products. In January and July of 2022, the DHHS, Department of Labor, and Treasury Department jointly issued guidance on implementation of
this  ACA  mandate,  among  other  things.  The  federal  guidance  makes  clear  that  all  FDA-approved  or  cleared  contraceptive  products  that  are  determined  by  an
individual’s  medical  provider  to  be  medically  appropriate  for  such  individual  must  be  covered  without  cost  sharing,  regardless  of  whether  the  product  is  specifically
identified in a Birth Control Guide published by the FDA. Any future repeal or elimination of the ACA’s preventive care coverage rules would mean that women seeking
to  use  prescribed  forms  of  contraceptives  may  have  to  pay  some  portion  of  the  cost  for  such  products  out-of-pocket,  which  could  deter  some  women  from  using
prescription  contraceptive  products  or  branded  prescription  contraceptive  products,  including  Ovaprene  and  our  other  investigational  contraceptive  products,  if  and
when approved by the FDA.

As no FDA-approved treatments for FSAD currently exist, there is little precedent to help assess whether health insurance plans will cover Sildenafil Cream,
if approved.

Sildenafil Cream is being developed for female sexual arousal disorder, a life altering, but not a life threatening, condition. Hence, there is no assurance that
third-party reimbursement will be available for Sildenafil Cream, if approved. Even if reimbursement becomes available, the amount of such reimbursement may not
make our product affordable to women and profitable to us. Insurers may deem Sildenafil Cream to be a lifestyle drug and decide not to provide reimbursement. Today,
many health insurance plans provide reimbursement for male sexual arousal medications. However, we cannot predict whether they will continue to do so or whether
they will do so for FSAD treatments as well. The safety and efficacy data from our clinical trials may impact whether Sildenafil Cream will become eligible for insurance
coverage, and if it does, the level of such reimbursement. In an environment of rapidly rising health care costs, insurers have been looking for ways to reduce costs,
which  could  make  it  difficult  for  new  therapies  to  gain  coverage  if  they  are  not  deemed  medically  critical  or  essential.  If  Sildenafil  Cream  fails  to  obtain  insurance
coverage, or if the patient’s share of the cost is deemed to be expensive, a market may never develop for Sildenafil Cream, which would have a material adverse effect
on our financial condition and prospects.

The  commercial  success  of  products  we  develop,  if  approved,  will  be  impacted  by  the  prescribing  information  approved  by  the  FDA  and  comparable
regulatory authorities outside the U.S.

The commercial success of any products we develop will significantly depend upon our ability, or that of our commercial collaborator, to obtain approval from
the  FDA  and  other  regulatory  authorities  of  prescribing  information  for  the  product  that  adequately  describes  expected  features  or  benefits.  Failure  to  achieve  such
approval will prevent or substantially limit our or our collaborators’ ability to advertise and promote such features and benefits in order to differentiate our products from
competing products. This failure could have a material adverse effect on our business, financial condition, results of operations and prospects.

Drug products and drug/device combination products are complex to manufacture, and manufacturing disruptions may occur that could cause significant
delays and disruption in the commercial supply of any product we develop, if approved.

The manufacture of our product candidates is complex, subject to compliance with extensive regulatory requirements and we are dependent on, and expect to
continue to rely on, contract manufacturers and other third parties to supply our products and their components. Manufacturing disruptions may occur, including as a
result of scaling up production to meet commercial requirements or due to global supply chain disruptions. Such problems may prevent the production of lots that meet
the specifications required for sale of a product and may be difficult and expensive to resolve. To the extent we or our commercial collaborators rely on single source
contract manufacturers and suppliers, if disruptions occur in the operations of any one of those third parties, there may be immediate shortages of our products. If any
such  issues  were  to  arise,  we  could  lose  sales  and  associated  revenue,  incur  additional  costs,  delay  commercial  launch  of  new  products  or  suffer  harm  to  our
reputation.

84

See above: “Risks Related to Product Research & Development and Regulatory Approval- Delays in the manufacture of our clinical supplies as well as other
supply  chain  disruptions  could  postpone  the  initiation  of  or  interrupt  clinical  studies,  extend  the  timeframe  and  cost  of  development  of  our  product  candidates,  delay
potential regulatory approvals and impact the commercialization of any approved products.”; “Risks Related to Our Dependence on Third Parties- We do not have, and
we do not have plans to establish, our own manufacturing capabilities and instead rely on third-party suppliers and manufacturers for clinical study materials, including
multiple single source suppliers and manufacturers. If these third parties do not perform as we expect, do not maintain their regulatory approvals or become subject to
negative circumstances, it could delay, prevent or impair our product development or commercialization efforts, or those of our collaborators, and harm our business;”
and  “Risks  Related  to  Our  Dependence  on  Third  Parties-  In  some  cases,  we  may  be  contractually  required  to  obtain  clinical  or  commercial  product  supplies  from
specific  third  parties  or  there  may  be  a  limited  number  of  third-party  suppliers  of  raw  materials  and  other  components  of  our  product  candidates  or  future  products,
which may heighten our dependence on those third parties and the risk of manufacturing disruptions.”

If competitors obtain approval for generic versions of XACIATO or any future products, our business may suffer.

XACIATO and any future product may face direct competition from generic products earlier or more aggressively than anticipated, depending upon the product's
success in the market. In addition to creating the 505(b)(2) NDA pathway, the Hatch-Waxman Act amendments to the FDCA authorized the FDA to approve generic
drugs that are the same as drugs previously approved for marketing under the NDA provisions of the statute pursuant to abbreviated new drug applications, or ANDAs.
An ANDA relies on the nonclinical and clinical testing conducted for a previously approved reference listed drug, or RLD, and must demonstrate to the FDA that the
generic drug product is identical to the RLD with respect to the active ingredients, the route of administration, the dosage form, and the strength of the drug and also
that it is “bioequivalent” to the RLD. The FDA is prohibited by statute from approving an ANDA when certain marketing or data exclusivity protections apply to the RLD.
If a third party is able to demonstrate bioequivalence without infringing our patents or if a data exclusivity period granted to a product under the FDCA is successfully
challenged,  a  third  party  may  be  able  to  introduce  a  competing  generic  product  onto  the  market  before  the  expiration  of  the  applicable  patents  or  exclusivity  period
under the FDCA. Reduction or loss of periods of market exclusivity for our products could negatively affect our business, operating results and financial condition.

We  will  need  to  obtain  FDA  approval  of  any  proposed  prescription  medical  product  name,  and  any  failure  or  delay  associated  with  such  approval  may
adversely affect our business.

Any name we intend to use for our current or future product candidates will require approval from the FDA regardless of whether we have secured a formal
trademark  registration  from  the  U.S.  Patent  and  Trademark  Office,  or  USPTO.  The  FDA  typically  conducts  a  review  of  proposed  new  prescription  medical  product
names, including an evaluation of the potential for confusion with other product names. The FDA may also object to a proposed product name if it believes the name
inappropriately implies medical claims or contributes to an overstatement of efficacy. If the FDA objects to any of our proposed product names, we may be required to
adopt  alternative  names  for  our  product  candidates.  If  we  adopt  alternative  names,  we  would  lose  any  goodwill  or  brand  recognition  developed  for  previously  used
names  and  marks,  such  as  Ovaprene,  as  well  as  the  benefit  of  any  existing  trademark  applications  for  such  product  candidate  and  may  be  required  to  expend
significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe the existing rights of third
parties, and be acceptable to the FDA. We or a commercial collaborator may be unable to build a successful brand identity for a new trademark in a timely manner or at
all, which would limit our or our collaborator’s ability to commercialize our product candidates.

Even if we receive marketing approval from the FDA, we may fail to receive similar approvals outside the U.S., which could substantially limit the value of
our products.

To  market  any  future  product  outside  the  U.S.,  we,  or  our  commercial  collaborators,  must  obtain  separate  marketing  approvals  from  comparable  regulatory
authorities  for  each  jurisdiction  and  comply  with  numerous  and  varying  regulatory  requirements  of  other  countries,  including  clinical  trials,  commercial  sales,  pricing,
manufacturing, distribution and safety requirements. The time required to obtain approval in other countries might differ from, and be longer than, that required to obtain
FDA approval. Approval by the FDA or a comparable foreign authority does not ensure approval by regulatory authorities in any other countries or jurisdictions, but a
failure to obtain marketing approval in one jurisdiction may adversely impact the likelihood of approval in other jurisdictions. The marketing approval process in other
countries may include all of the risks associated with obtaining FDA approval in the U.S., as well as other risks. Further, for approval in foreign jurisdictions, we may not
have  rights  to  reference  the  necessary  clinical  and  nonclinical  data  that  we  do  not  own  or  have  licensed  rights  to  use,  as  we  anticipate  doing  under  the  505(b)(2)
regulatory pathway in the U.S., and we, or our commercial collaborator, may have to conduct further

85

nonclinical studies or clinical trials or develop other additional data to seek approvals in other jurisdictions. In addition, in many countries outside the U.S., a new product
must receive pricing and reimbursement approval prior to commercialization. This can result in substantial delays in these countries. Additionally, the product labeling
requirements outside the U.S. may be different and inconsistent with the U.S. labeling requirements, negatively affecting our ability to market our products in countries
outside the U.S.

In  addition,  we  may  be  subject  to  fines,  suspension  or  withdrawal  of  marketing  approvals,  product  recalls,  seizure  of  products,  operating  restrictions  and
criminal prosecution if we, or our commercial collaborator, fail to comply with applicable foreign regulatory requirements. In such an event, our ability, or our commercial
collaborator’s ability, to market to the full target market for our products will be reduced and the full market potential of our products may not be realized, which could
have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Employee Matters and Managing Our Growth

We have a relatively small number of employees to manage and operate our business.

As of March 27, 2024, we had 26 employees, of which 24 were full-time and five were part-time. Our focus on limiting cash utilization requires us to manage
and operate our business in a highly efficient manner, relying on consultants and other third-party service providers for product development and operational expertise
we require, and to limit full-time personnel resources. With a small number of employees, our ability to supervise the service providers we engage, including our CMOs
and CROs, may be constrained, which may impact the timing and quality of services we receive. No assurance can be given that we will be able to run our operations
or accomplish all of the objectives we otherwise would seek to accomplish with the limited personnel resources we currently have.

We generally allow for a hybrid work model. We instituted remote work policies in March 2020 in response to the COVID-19 pandemic and resulting government
stay-at-home orders, which have evolved into our current policies generally permitting a hybrid work schedule. In addition, many consultants, collaborators and other
third-party  service  providers  on  which  we  rely  currently  have  a  remote  or  hybrid  workforce  model.  The  long-term  impact  of  less  frequent  in-person  meetings  on  our
productivity and creativity is difficult to assess. Remote working arrangements for our personnel and that of third parties on which we rely may weaken our ability to
effectively manage and operate our business and lead to delays in our anticipated development program timelines.

In addition, due to our small workforce, if multiple employees were to become unable to work for a protracted period for any reason, or if they were to resign at
roughly the same time, our business could suffer. Our ability to effectively manage and operate our business could become significantly impaired and our expenses
could increase materially, including as a result of expenditures related to recruiting, hiring and training qualified new employees and engaging additional consultants and
service  providers  to  perform  the  job  responsibilities  of  the  employees  on  leave  or  who  resign.  If  we  or  our  collaborators  or  service  providers  experience  staffing
shortages, it may result in significant delays in our anticipated development program timelines.

If we fail to attract and retain management and other key personnel, we may not successfully complete development of, obtain regulatory approval for or
commercialize our product candidates, or otherwise implement our business plan.

Our ability to compete in the highly competitive biopharmaceutical industry depends upon our ability to attract and retain highly qualified managerial and key
personnel. We depend highly on our senior management. Losing the services of our senior management, and our chief executive officer in particular, could impede,
delay  or  prevent  the  development  and  commercialization  of  our  product  candidates,  harm  our  ability  to  raise  additional  funds  and  negatively  impact  our  ability  to
implement our business plan. If we lose the services of any of our senior management team, we might not find suitable replacements on a timely basis or at all, and our
business could be materially harmed. We do not maintain “key man” insurance policies on the lives of any of our senior management employees.

We  might  not  attract  or  retain  qualified  management  and  other  key  personnel  in  the  future  due  to  the  intense  competition  for  qualified  personnel  among
biopharmaceutical  companies  and  other  life  sciences  R&D  organizations,  particularly  in  the  San  Diego  area  where  we  are  headquartered.  In  addition,  our  limited
personnel and financial resources may result in greater workloads for our employees compared to those at companies with which we compete for personnel, which may
lead to higher levels of employee burnout and turnover. Many of the other companies with whom we compete for qualified personnel have greater financial and other
resources, different risk profiles and longer histories in the industry than we do. They also may provide more diverse opportunities and better opportunities for career
advancement. If we cannot attract and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will harm our ability to
implement our business strategy and achieve our business objectives.

86

New legal precedent, laws and regulations could make it costlier or more difficult for us to obtain certain types of insurance, including director and officer liability
insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the coverage that is the same or similar to
our current coverage. The impact of these events could also make it more difficult for us to attract or retain qualified persons to serve as our senior management or on
our board of directors.

We  may  not  be  successful  in  our  efforts  to  identify  and  acquire  or  in-license  additional  product  candidates  or  technologies,  which  may  limit  our  growth
potential.

Our business development strategy involves identifying and acquiring or in-licensing potential product candidates or technologies. We assembled our current
portfolio  of  product  candidates  through  the  acquisition  of  companies  and  assets  and  in-licensing  transactions  beginning  in  2017.  We  may  engage  in  strategic
transactions that could cause us to incur additional liabilities, commitments or significant expense.

These efforts may not be successful, including for reasons discussed in elsewhere in this Risk Factors section and also:

• we may fail to appropriately evaluate the potential risks and uncertainties associated with a transaction;
•

there may be intense competition to acquire or in-license promising product candidates and technologies and many of our competitors have considerably
more financial, development and commercialization resources than we have;

• we may not effectively integrate the acquired or in-licensed assets, businesses, personnel, intellectual property or business relationships;
• we may underestimate the development and regulatory approval challenges, costs and timelines and overestimate the market opportunity for the potential

product candidates and technologies; and

•

during development, the acquired or in-licensed product candidates may not prove to be safe or effective in their targeted indications.

We may fail to realize the anticipated value of any strategic transaction and the costs of a transaction may outweigh the benefits we realize from it. In addition,
we  have  used  shares  of  our  common  stock  as  consideration  in  strategic  transactions  and  we  may  do  so  in  the  future,  which  may  result  in  significant  dilution  to  our
stockholders. Any strategic transaction we pursue may not produce the outcomes and benefits we originally anticipated and may adversely impact our operating results
and financial condition and be detrimental to our company in general.

Risks Related to Our Intellectual Property

Our  failure  to  adequately  protect  or  enforce  our  and  our  licensors’  intellectual  property  rights  could  materially  harm  our  proprietary  position  in  the
marketplace or prevent or impede the commercialization of our current and potential future products.

Our success depends in part on our ability, and the ability of our licensors, to obtain and maintain protection in the U.S. and other countries for the intellectual
property covering or incorporated into our technologies and products. Many of the patents and patent applications relied upon by us are licensed to us by third parties.
Our ability, or the ability of our licensors, to protect our product candidates from unauthorized use or infringement by third parties depends substantially on our abilities
and the abilities of such licensors to obtain and maintain, or license, valid and enforceable patents. Due to evolving legal standards relating to the patentability, validity
and enforceability of patents covering pharmaceutical inventions and the scope of claims made under these patents, our ability, and that of our licensors, to obtain or
enforce  patents  is  uncertain  and  involves  complex  legal  and  factual  questions  for  which  important  legal  principles  are  unresolved.  As  a  result,  the  validity  and
enforceability of patents cannot be predicted with certainty. In addition, we do not know whether we or our licensors were the first to make the inventions covered by
each of our issued patents and pending patent applications. We or our licensors may not have been the first to file patent applications for these inventions.

Periodic maintenance fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent.
The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions
during  the  patent  application  process.  While  an  inadvertent  lapse  can  in  many  cases  be  cured  by  payment  of  a  late  fee  or  by  other  means  in  accordance  with  the
applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss
of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent

87

application  include,  but  are  not  limited  to,  failure  to  respond  to  official  actions  within  prescribed  time  limits,  non-payment  of  fees  and  failure  to  properly  legalize  and
submit formal documents. In such an event, our competitors might be able to enter the market, which would have a material adverse effect on our business.

We cannot be certain if any of the patents that cover our product candidates will be eligible to be listed in the Orange Book following a drug product marketing
approval. The advantage of being listed in the Orange Book is that, under the Hatch-Waxman Act, any future generic applicant for any of our approved products needs
to include a patent certification in their generic application with respect to each patent listed in the Orange Book for an approved product (referred to as the “listed drug”)
for which they are seeking approval. If the generic applicant believes that any of the patents in the Orange Book on the listed drug is invalid, unenforceable, or not
infringed by their product, the generic applicant usually will file a “Paragraph IV” certification on that patent if they plan to challenge the patent. When a generic applicant
files a Paragraph IV certification, they must provide the listed drug applicant (and the patent owner if different) a notice that they filed a generic application with the
Paragraph IV certification. If, in reply to that notice, the listed drug holder files a patent lawsuit against the generic applicant within 45 days of the Paragraph IV notice, a
30-month  automatic  stay  is  imposed  by  the  Hatch-Waxman  Act  on  FDA  during  which  FDA  may  not  approve  the  generic  application  (unless  the  patent  litigation  is
resolved in the generic applicant’s favor). These 30-month stays are major protection available in the Hatch-Waxman Act for innovative drug makers. However, if our
products are approved, but one or more of our patents are not listed in the Orange Book, generic firms that might seek approval of a generic version of our product
would not have to “certify” in their generic drug applications as to any such unlisted patent. This could result in the absence of a 30-month stay and thus faster approval
of some generic applications for our products.

Other companies or individuals may independently develop similar or alternative technologies or duplicate our technologies. This could enable our competitors
to develop a competing product that avoids infringing our patents. In such an event, our competitors might be able to enter the market, which could significantly harm
the commercial opportunity for our product candidates.

The  laws  of  some  foreign  countries  do  not  protect  our  proprietary  rights  to  the  same  extent  or  in  the  same  manner  as  U.S.  laws,  and  we  may  encounter
significant problems in protecting and defending our proprietary rights in these countries. We will be able to protect our proprietary rights from unauthorized use by third
parties only to the extent that our proprietary technologies, products and product candidates are covered by valid and enforceable patents or are effectively maintained
as trade secrets.

As an example, the complexity and uncertainty of European laws have increased in recent years. In Europe, a new unitary patent system was launched on
June  1,  2023,  which  significantly  impacted  European  patents,  including  those  granted  before  the  introduction  of  such  a  system.  Under  the  unitary  patent  system,
European applications now have the option, upon grant of a patent, of becoming a Unitary Patent which are subject to the jurisdiction of the Unitary Patent Court (UPC).
As the UPC is a new court system, there is no precedent for the court, increasing the uncertainty of litigation. Patents granted before the implementation of the UPC
have the option of opting out of the jurisdiction of the UPC and remaining as national patents in the UPC countries. Patents that remain under the jurisdiction of the UPC
will be potentially vulnerable to a single UPC-based revocation challenge that, if successful, could invalidate the patent in all countries who are signatories to the UPC.
We cannot predict with certainty the long-term effects of any potential changes.

Our  patent  strategy  for  protecting  Ovaprene  includes  in-licensing  several  patent  families  from  ADVA-Tec.  Patent  prosecution  for  the  intellectual  property

incorporated into Ovaprene is entirely controlled by ADVA-Tec and we have little, if any, influence or control over such patent prosecution.

Our patent strategy for protecting Sildenafil Cream includes in-licensing a patent family from SST, whose last U.S. claim expires in June 2029, but which could
be  eligible  for  three-year  market  exclusivity  under  the  Hatch-Waxman  Act  in  the  U.S.  However,  if  granted  3-year  exclusivity,  generic  applicants  can  still  submit  an
abbreviated application during the 3-year period and the FDA is required to review the application, but will defer any approval until the end of the 3-year period. Three-
year  exclusivity  differs  from  5-year  exclusivity  under  the  Hatch-Waxman  Act,  which  bars  the  submission  of  a  generic  application  during  the  5-year  period,  with  the
exception that a generic application can be filed after 4 years if it contains a Paragraph IV certification challenging an Orange Book-listed patent for the brand drug.

With respect to patents related to Sildenafil Cream, SST has the sole right, but not the obligation, to prepare, file, prosecute and maintain such patents. We will
be  responsible  for  the  costs  incurred  to  maintain  and  prosecute  all  such  patents  and  we  will  be  kept  informed  of  all  strategies.  However,  we  will  have  little  if  any,
influence or control over implementing the patent strategy.

With respect to patent rights related to our IVR product candidates, including DARE-HRT1 and DARE-FRT1, The General Hospital Corporation (also known as
Massachusetts General Hospital or MGH) has the sole right to prosecute and maintain its patent rights, and we have the right to prosecute and maintain Catalent's
patent rights. We

88

will be responsible for the costs incurred by MGH to maintain and prosecute such patents and we will be kept informed of all strategies. However, we will have little, if
any, influence or control over MGH’s implementation of the patent strategy.

With  respect  to  patents  related  to  DARE-VVA1,  we  have  the  right  and  obligation,  at  our  expense,  to  prosecute  and  maintain  the  in-licensed  patent  rights  in

certain major markets, if possible.

With respect to patents rights related to our DARE-GML program, the University of Minnesota (UMN) has the sole right to prosecute and maintain its patent
rights, and we have the right to prosecute and maintain patents licensed from Hennepin Life Sciences. We will be responsible for the costs incurred by UMN to maintain
and prosecute such patents and we will be kept informed of all strategies. However, we will have little, if any, influence or control over UMN's implementation of the
patent strategy.

With respect to patent rights licensed from Douglas and underlying patent rights from University of Manchester, Douglas has the sole right to prosecute and
maintain  those  patent  rights.  We  will  be  responsible  for  the  costs  incurred  by  Douglas  to  maintain  and  prosecute  such  patents  and  we  will  be  kept  informed  of  all
strategies. However, we will have little, if any, influence or control over Douglas's implementation of the patent strategy.

There is a substantial backlog of patent applications at the USPTO that may lead to delays in having patent applications examined by the USPTO. There can be
no assurance that any patent applications relating to our products or methods will be issued as patents or, if issued, that the patents will not be challenged, invalidated
or circumvented or that the rights granted thereunder will provide a competitive advantage. We and our licensors may not obtain patent rights on products, treatment
methods or manufacturing processes that we may develop or to which we may obtain license or other rights. Even if patents are issued to us and our licensors, rights
under any issued patents may not provide us with sufficient protection for our product candidates or provide sufficient protection to afford us a commercial advantage
against our competitors or their competitive products or processes. It is possible that no patents will be issued from any pending or future patent applications owned by
us or licensed to us. Others may challenge, seek to invalidate, infringe or circumvent any patents we own or license, including the patents we have licensed to date and
any other patents we may license in the future. Conversely, in the future we may have to initiate litigation against third parties to enforce our intellectual property rights.
The  defense  and  enforcement  of  patent  and  intellectual  property  claims  are  both  costly  and  time  consuming,  even  if  the  outcome  is  favorable  to  us.  Any  adverse
outcome could subject us to significant liabilities, require us to license disputed rights from others or require us to cease selling our future products.

In addition, many other organizations are engaged in research and product development efforts that may overlap with our products. Such organizations may
currently  have,  or  may  obtain  in  the  future,  legally  blocking  proprietary  rights,  including  patent  rights,  in  one  or  more  products  or  methods  we  are  developing  or
considering for development. These rights may prevent us from commercializing technology, or they may require us to obtain a license from the organizations to use the
technology.  We  may  not  obtain  any  such  licenses  that  may  be  required  on  reasonable  financial  terms,  if  at  all,  and  there  can  be  no  assurance  that  the  patents
underlying any such licenses will be valid or enforceable. As with other companies in the pharmaceutical industry, we are subject to the risks that persons located in
other countries will engage in development, marketing or sales activities of products that would infringe our intellectual property rights if such activities were conducted
in the U.S. and enforcing our intellectual property rights against such persons may be difficult or not possible.

Our patents and other intellectual property also may not afford protection against competitors with similar technology. We may not have identified all patents,
published  applications  or  published  literature  that  affect  our  business  either  by  blocking  our  ability  to  commercialize  our  product  candidates,  by  preventing  the
patentability of our products or by covering the same or similar technologies that may affect our ability to market or license our product candidates. Many companies
have  encountered  difficulties  in  protecting  and  defending  their  intellectual  property  rights  in  foreign  jurisdictions.  If  we  encounter  such  difficulties  or  are  otherwise
precluded from effectively protecting our intellectual property rights in either the U.S. or foreign jurisdictions, our business prospects could be substantially harmed.

In  addition,  because  of  funding  limitations  and  our  limited  cash  resources,  we  may  not  be  able  to  devote  the  resources  that  we  might  otherwise  desire  to

prepare or pursue patent applications, either at all or in all jurisdictions in which we might desire to obtain patents, or to maintain already-issued patents.

The patents and the patent applications covering Sildenafil Cream and XACIATO are limited to specific formulations, processes and uses of sildenafil and
clindamycin, and our market opportunity may be limited

89

by  the  lack  of  patent  protection  for  the  active  ingredient  itself  and  other  formulations  and  delivery  technology  and  systems  that  may  be  developed  by
competitors.

The active ingredient in our product candidate for FSAD, Sildenafil Cream, is sildenafil and the active ingredient in our FDA-approved product for the treatment
of bacterial vaginosis, XACIATO, is clindamycin. Patent protection for these ingredients has expired and generic products are available. As a result, a competitor that
obtains the requisite regulatory approvals could offer products with the same active ingredient in a different formulation so long as the competitor does not infringe any
process, use or formulation patents that we have developed, or that may not be barred by any three-year Waxman-Hatch Act exclusivity, or any GAIN Act extension
thereof, we might enjoy upon approval of our products.

Competitors  may  seek  to  develop  and  market  competing  formulations  that  may  not  be  covered  by  our  patents  and  patent  applications.  The  commercial
opportunity for Sildenafil Cream and XACIATO could be significantly harmed if competitors are able to develop and commercialize alternative formulations using these
ingredients.

The patents and the patent applications covering our IVR product candidates cover the method of delivery and the device and our market opportunity may
be  limited  by  the  lack  of  patent  protection  for  the  active  ingredients  themselves  and  other  formulations,  delivery  technology  and  systems  that  may  be
developed by competitors.

The active ingredients in our IVR product candidates include bio-identical progesterone, estrogen and oxybutynin, and none of those ingredients are proprietary
to us. As a result, we must compete with currently available products and any future products developed by competitors using same active ingredients in a different
formulation  or  via  a  different  delivery  system.  The  commercial  opportunity  for  our  IVR  product  candidates,  including  DARE-HRT1  for  hormone  therapy,  could  be
significantly harmed if competitors develop and commercialize alternative formulations or better delivery approaches.

The  patents  and  the  patent  applications  covering  the  use  and  delivery  of  DARE-VVA1  and  our  market  opportunity  may  be  limited  by  the  lack  of  patent
protection for the active ingredient itself and other formulations, delivery technology and systems that may be developed by competitors.

The active ingredient in DARE-VVA1, tamoxifen, is not proprietary to us. As a result, we must compete with currently available products and any future products
developed  by  competitors  using  the  same  active  ingredient  in  a  different  formulation  or  via  a  different  delivery  system.  The  commercial  opportunity  for  our  product
candidate  for  the  treatment  of  vulvar  and  vaginal  atrophy  could  be  significantly  harmed  if  competitors  develop  and  commercialize  alternative  formulations  or  better
delivery approaches.

We  may  become  involved  in  patent  litigation  or  other  intellectual  property  proceedings  relating  to  our  future  product  approvals,  which  could  result  in
liability for damages or delay or stop our development and commercialization efforts.

The pharmaceutical industry has been characterized by significant litigation and other proceedings regarding patents, patent applications, trademarks and other
intellectual property rights. The situations in which we may become party to such litigation or proceedings may include any third parties initiating litigation claiming that
our products infringe their patent or other intellectual property rights, or that one of our trademarks or trade names infringes the third party’s trademark rights; in such
case, we would need to defend against such proceedings. The costs of resolving any patent litigation or other intellectual property proceeding, even if resolved in our
favor, could be substantial. Many of our potential competitors will be able to sustain the cost of such litigation and proceedings more effectively than us because of their
substantially  greater  resources.  Uncertainties  resulting  from  the  initiation  and  continuation  of  patent  litigation  or  other  intellectual  property  proceedings  could  have  a
material  adverse  effect  on  our  ability  to  compete  in  the  marketplace,  our  financial  condition  and  our  stock  price.  Patent  litigation  and  other  intellectual  property
proceedings may also consume significant management time.

If a competitor infringes upon our patent or other intellectual property rights, including any rights licensed by us, enforcing those rights may be costly, difficult
and time-consuming. Even if successful, litigation to enforce our intellectual property rights or to defend our patents against challenge could be expensive and time-
consuming and could divert our management’s attention. We may not have sufficient resources to enforce our intellectual property rights or to defend our patent or other
intellectual property rights against a challenge. If we were unsuccessful in enforcing and protecting our intellectual property rights and protecting our products, it could
materially harm our business.

With respect to XACIATO, we have the initial right to enforce patents we license from TriLogic and MilanaPharm against third parties whose activities infringe
such  patents  in  a  manner  that  could  affect  our  exercise  of  the  licenses  granted  to  us,  and  TriLogic  and  MilanaPharm  must  reasonably  cooperate  in  any  such  suit,
including, if

90

necessary, by being joined as a party to any such suit. In some cases, MilanaPharm may assume the defense of a claim initiated by a third-party alleging infringement
of a third party’s intellectual property rights as a result of the manufacture or sale of a product we develop under our license agreement with TriLogic/MilanaPharm.
While  our  license  agreement  would  require  MilanaPharm  to  indemnify  us  for  certain  losses  arising  from  these  third-party  claims,  this  indemnification  may  not  be
sufficient to adequately compensate us for any related losses or the potential loss of our ability to manufacture and sell XACIATO. Additionally, our license agreement
with Organon requires that we indemnify Organon from and against all liabilities, damages, expenses, fines, penalties and losses as a result of any third-party claim
arising out of or relating to the development, manufacture, commercialization or other exploitation of XACIATO or any licensed product by or on behalf of us or any
affiliate or licensee of ours, except for in limited circumstances. As a result of our indemnification obligations to Organon and limitations on TriLogic's and MilanaPharm's
obligations to indemnify us, any patent infringement litigation relating to XACIATO could subject us to significant liabilities that may have a material adverse effect on our
business, results of operations and financial condition.

With respect to Ovaprene, ADVA-Tec has the right, in certain instances, to control the defense against any infringement litigation arising from the manufacture
or development (but not the sale) of Ovaprene. While our license agreement with ADVA-Tec requires ADVA-Tec to indemnify us for certain losses arising from these
claims, this indemnification may not be sufficient to adequately compensate us for any related losses or the potential loss of our ability to manufacture and develop
Ovaprene. Additionally, our license agreement with Bayer requires that we indemnify Bayer from and against all liabilities, damages, losses and expenses arising from
or occurring as a result of development, manufacture, use or commercialization of Ovaprene by us or any licensee of ours, including without limitation, product liability
claims, except in limited circumstances. As a result of our indemnification obligations to Bayer and limitations on ADVA-Tec’s obligations to indemnify us, any patent
infringement litigation relating to Ovaprene could subject us to significant liabilities that may have a material adverse effect on our business, results of operations and
financial condition.

With respect to Sildenafil Cream, we have the initial right to enforce the applicable licensed patents against infringers in the field of use where a third party is
exploiting  a  topically  applied  pharmaceutical  product  that  contains  at  least  one  of  the  same  active  pharmaceutical  ingredients  as  a  licensed  product,  and  SST  will
provide us with reasonable assistance (excluding financial assistance), at our expense. We also have the initial right to defend any claim initiated by any third-party
alleging that a licensed product developed or commercialized under the SST license agreement has infringed any third-party intellectual property rights. While the SST
license agreement requires SST to indemnify us for certain losses arising from these claims, this indemnification may not be sufficient to adequately compensate us for
any related losses or the potential loss of our ability to manufacture and develop Sildenafil Cream.

With respect to our IVR product candidates, including DARE-HRT1, DARE-FRT1, and DARE-PTB1 we have the first right to enforce the applicable licensed

patents against third party infringers in the fields of pharmaceutical, therapeutic, preventative, diagnostic and palliative uses.

With respect to DARE-VVA1, we have the first right to enforce the applicable licensed patents against third-party infringers in all fields.

We cannot guarantee that we or any of our licensors’ patent searches or analyses, including but not limited to the identification of relevant patents, the scope of
patent  claims  or  the  expiration  of  relevant  patents,  are  complete  or  thorough,  nor  can  we  be  certain  that  we  have  identified  each  and  every  third-party  patent  and
pending  application  in  the  U.S.,  Europe  and  elsewhere  that  is  relevant  to  or  necessary  for  the  commercialization  of  our  product  candidates  in  any  jurisdiction.  For
example, in the U.S., applications filed before November 29, 2000 and certain applications filed after that date that will not be filed outside the U.S. remain confidential
until patents issue. Patent applications in the U.S., EU and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with
such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our future product candidates, or their manufacture or
use may currently be unpublished. Additionally, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner
that could cover our product candidates or the use of our product candidates. The scope of a patent claim is determined by an interpretation of the law, the written
disclosure in a patent and the patent’s prosecution history. Our or our licensors’ interpretation of the relevance or the scope of a patent or a pending application may be
incorrect, which may negatively impact our ability to market our product candidates. We or our licensors may incorrectly determine that our product candidates are not
covered  by  a  third-party  patent  or  may  incorrectly  predict  whether  a  third  party’s  pending  application  will  issue  with  claims  of  relevant  scope.  Our  or  our  licensors’
determination of the expiration date of any patent in the U.S., the EU or elsewhere that we consider relevant may be incorrect, which may negatively impact our ability
to develop and market our product candidates. Our licensors’ failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and
market our product candidates.

91

From  time  to  time,  we  or  our  licensors  may  identify  patents  or  applications  in  the  same  general  area  as  our  products  and  product  candidates.  We  or  our
licensors may determine these third-party patents are irrelevant to our business based on various factors including our or our licensors’ interpretation of the scope of the
patent claims and our or our licensors’ interpretation of when the patent expires. If the patents are asserted against us, however, a court may disagree with our or our
licensors’ determinations. Further, while we or our licensors may determine that the scope of claims that will issue from a patent application does not present a risk, it is
difficult to accurately predict the scope of claims that will issue from a patent application, our determination may be incorrect, and the issuing patent may be asserted
against us or our licensors. We cannot guarantee that we or our licensors will be able to successfully settle or otherwise resolve such infringement claims. If we or our
licensors fail in any such dispute, in addition to being forced to pay monetary damages, we may be temporarily or permanently prohibited from commercializing our
product candidates. We or our licensors might, if possible, also be forced to redesign our product candidates so that we or our licensors no longer infringe on the third-
party  intellectual  property  rights.  Any  of  these  events,  even  if  we  or  our  licensors  were  ultimately  to  prevail,  could  require  us  to  divert  substantial  financial  and
management resources that we would otherwise be able to devote to our business.

We also rely upon trade secrets to protect our technology, product and product candidates, and trade secrets can be difficult to maintain and enforce.

In addition to patent and trademark protection, we also rely on trade secrets, including unpatented know-how, technology and other proprietary information, to
derive  a  competitive  advantage  for  products  we  develop,  especially  where  we  believe  patent  protection  is  not  appropriate  or  obtainable.  However,  trade  secrets  are
difficult to maintain. Monitoring unauthorized uses and disclosures of our intellectual property is difficult, and we do not know whether the steps we have taken to protect
our  intellectual  property  will  be  effective.  Moreover,  we  or  any  of  our  collaborators’  employees,  consultants,  contractors  or  scientific  and  other  advisors  may
unintentionally  or  willfully  disclose  our  proprietary  information  to  competitors  and  we  may  not  have  adequate  remedies  in  respect  of  that  disclosure.  Enforcement  of
claims that a party illegally disclosed or obtained and is using trade secrets is difficult, expensive and time consuming and the outcome is unpredictable. In addition,
foreign courts are sometimes less willing than U.S. courts to protect trade secrets. If our competitors independently develop equivalent knowledge, methods and know-
how, we would not be able to assert our trade secrets against them and our business could be harmed.

Our  competitors  may  independently  develop  knowledge,  methods  and  know-how  equivalent  to  our  trade  secrets.  Competitors  may  be  able  to  legally  obtain
products  of  ours  and  replicate  some  or  all  of  the  competitive  advantages  we  derive  from  our  development  efforts  for  technologies  on  which  we  do  not  have  patent
protection. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to
whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed
by a competitor, our competitive position could be harmed.

Confidentiality  agreements  with  employees  and  others  may  not  adequately  prevent  disclosure  of  our  know-how,  trade  secrets  and  other  proprietary
information and may not adequately protect our intellectual property, which could limit our ability to compete.

We  enter  into  confidentiality  and  nondisclosure  agreements  with  our  employees,  CROs,  CMOs,  consultants,  collaborators,  sponsored  researchers,  and
scientific  and  other  advisors.  These  agreements  generally  require  that  the  other  party  keep  confidential  and  not  disclose  to  third  parties  all  confidential  information
developed by the party on our behalf or made known to the party by us during the course of the party’s relationship with us. We also enter into intellectual property
assignment  agreements  with  our  employees,  consultants  and  certain  other  service  providers,  which  generally  provide  that  inventions  conceived  by  the  party  in  the
course of rendering services to us will be our exclusive property. However, these agreements may not be honored or may not effectively assign intellectual property
rights to us. We have not entered into any non-compete agreements with any of our employees. We cannot guarantee that the confidential nature of our proprietary
information will be maintained by our employees and others in the course of their future employment with or provision of services to a competitor. Enforcing a claim that
a  party  illegally  disclosed  or  obtained  and  is  using  our  know-how,  trade  secrets  or  other  proprietary  information  is  difficult,  expensive  and  time  consuming  and  the
outcome is unpredictable. If we are unable to prevent unauthorized material disclosure of our intellectual property to third parties, we will not be able to establish or
maintain a competitive advantage for the products we develop, which could materially adversely affect our business, operating results and financial condition.

Provisions  in  our  agreements  with  governmental  agencies  and  non-profit  organizations  may  affect  our  intellectual  property  rights  and  the  value  of  our
development programs to our company.

Certain of our product development activities have been funded, are being funded and may in the future be funded, by the U.S. government and/or not-for-profit

organizations. Our agreements for these sources of funding

92

include, and may in the future include, terms and conditions that affect our intellectual property rights. For example, under our CRADA with NICHD for the Phase 3
clinical study of Ovaprene, the U.S. government has a nonexclusive, nontransferable, irrevocable, paid-up right to practice for research or other government purposes
any invention of either party conceived or first actually reduced to practice in the party’s performance of the CRADA and both parties will jointly own inventions jointly
invented  by  their  employees  in  performing  the  research  plan.  Under  the  CRADA,  we  were  granted  an  exclusive  option  to  negotiate  an  exclusive  or  nonexclusive
development and commercialization license with a field of use that does not exceed the scope of the research plan to rights that the U.S. government may have in
inventions jointly or independently invented by NICHD employees for which a patent application is filed.

The U.S. federal government retains certain rights in inventions produced with its financial assistance. Under the Bayh-Dole Act, the federal government retains
a  nonexclusive,  nontransferable,  irrevocable,  paid-up  license  for  its  own  benefit.  The  Bayh-Dole  Act  also  provides  federal  agencies  with  “march-in”  rights.  March-in
rights  allow  federal  agencies,  in  specified  circumstances,  to  require  the  recipient  of  federal  funding  (the  contractor)  or  successors  in  title  to  the  patent  to  grant  a
nonexclusive, partially exclusive or exclusive license to a third party if it determines that (i) adequate steps have not been taken to achieve practical application of the
invention,  (ii)  government  action  is  necessary  to  meet  public  health  or  safety  needs,  (iii)  government  action  is  necessary  to  meet  requirements  for  public  use  under
federal regulations or (iv) unless the requirement has been waived, the contractor has failed to substantially manufacture in the U.S. any product embodying the subject
invention that is intended for U.S. commerce. If the contractor or its successor refuses to do so, the government may grant the license itself. The federal government
also has the right to take title to these inventions if the contractor or its successor fails to disclose the invention to the government or fails to file an application to register
the intellectual property within specified time limits. To date, no federal agency has ever exercised march-in rights; however, the Biden administration has announced
that it views march-in rights as a legitimate means for the government to address rising pharmaceutical costs and future use of march-in rights by the government is
uncertain. Any exercise by the government of march-in rights could harm our competitive position, business, financial condition, results of operations and prospects.

Under the grant agreements supporting development of DARE-LARC1 and DARE-LBT, we agreed to make DARE-LARC1, DARE-LBT and any other products,
services, processes, technologies, materials, software, data, other innovations, and intellectual property resulting from the respective projects funded by the respective
grants (referred to as Funded Developments), available and accessible at an affordable price to people most in need within developing countries, and to promptly and
broadly disseminate the knowledge and information gained from the project funded by the grant (referred to as the Global Access Commitment). In connection with the
Global Access Commitment, under the agreement, we also granted the foundation that awarded the grant a nonexclusive, perpetual, irrevocable, worldwide, royalty-
free,  fully  paid  up,  sublicensable  license  to  make,  use,  sell,  offer  to  sell,  import,  distribute,  copy,  create  derivative  works,  publicly  perform,  and  display  Funded
Developments and essential background technology (referred to as the Humanitarian License). We are required to ensure that the Humanitarian License survives the
assignment or transfer of Funded Developments and essential background technology. Our obligations under the Global Access Commitment and the Humanitarian
License may limit the value to us of DARE-LARC1 and other Funded Developments.

Risks Related to Our Business Operations and Industry

Business  interruptions  resulting  from  public  health  crises,  natural  disasters  or  telecommunication  and  electrical  failures  may  materially  and  adversely
affect our business, operating results and financial condition.

We  may  experience  significant  business  disruptions  as  a  result  of  a  public  health  emergency,  natural  or  man  made  disaster,  act  of  terrorism,  war,  or
telecommunications or electrical failure that impacts our facilities or employees, or those of the third parties on which we rely for key business activities. The effects of
such events or conditions may materially and adversely affect our product development activities in the future, including as a result of:

•
•
•
•

•

difficulties and delays in clinical study site initiation, including due to diversion of healthcare resources away from conducting clinical studies;

difficulties and delays in recruiting and enrolling clinical study participants and conducting follow-up visits;

interruption of key clinical study activities, such as study site and data monitoring, due to limitations on travel or in-person gatherings;

staff disruptions and turnover internally or at our CMOs, CROs, clinical study sites, collaborators or other third parties on which we rely, either directly or
indirectly as a result of reallocation of resources, illness, vaccine mandates or other changes in terms of employment;

delays in receiving approval from regulatory authorities or IRBs to initiate our clinical studies;

93

•

•
•

•
•

•

•

difficulties and delays in production of clinical trial materials and commercial product, including due to supply chain disruptions or resource constraints or
reallocation on the part of our CMOs and raw materials suppliers;

interruptions in U.S. or global shipping that may affect the transport and delivery of raw materials, clinical study materials and commercial product;

changes in local regulations in response to a public health emergency or other emergency situation that may require changes in the ways our clinical studies
are conducted, require us to discontinue a clinical study, or make it more difficult for commercial and medical affairs field teams to call on or otherwise access
healthcare providers;

patient delays in seeking or receiving treatment, either due to fear of infection or inaccessibility of healthcare providers;

delays in interactions with the FDA or a foreign regulatory authority necessary to advance clinical development of our product candidates, or delays in their
review process and timing of potential approval of our product candidates, including delays in pre-approval manufacturing or clinical study site inspections;

difficulties and delays in establishing or maintaining strategic commercial or development collaborations due to the reallocation of resources or shifting business
strategies of collaborators or potential collaborators away from the women’s health market in general or our areas of focus within women’s health in particular;
or

disruption and volatility in the financial markets which negatively impacts our access to additional capital or stock price.

For example, in March 2020, the COVID-19 pandemic began to impact the global economy. Because of its size and breadth and the continued emergence of
new variants, all of the direct and indirect consequences of the COVID-19 pandemic are not yet known and may not emerge for some time. The COVID-19 pandemic
disrupted  our  product  development  activities  and  the  business  activities  of  third  parties  on  which  we  rely.  The  COVID-19  pandemic  contributed  to  a  slower  than
anticipated pace of enrollment of participants in our exploratory Phase 2b RESPOND clinical study of Sildenafil Cream as a result of operational restrictions or closure
of  certain  study  sites  due  to  their  adherence  to  governmental  guidelines  intended  to  reduce  the  spread  of  COVID-19.  The  COVID-19  pandemic  also  caused  us  to
prioritize advancement of certain of our development programs over others, or certain development activities within a program over others, due to anticipated or actual
difficulties and delays in recruiting clinical study sites and participants and obtaining clinical trial materials and supplies.

The  strategies  we  implement  designed  to  mitigate  the  effects  or  potential  effects  on  our  business  of  a  public  health  emergency  such  as  the  COVID-19
pandemic,  a  natural  or  manmade  disaster,  act  of  terrorism,  war  or  telecommunications  or  electrical  failure  that  impacts  our  facilities  or  employees  or  those  of  third
parties on which we rely may not be effective. The occurrence of such an event or condition could cause significant delays in the timelines for our clinical studies, our
regulatory submissions or potential marketing approvals of our product candidates, substantially increase our development costs, and delay or contribute to delays in
the  commercial  launch  of  any  approved  product  or  market  acceptance  of  the  product.  The  longer  such  an  event  or  condition  persists,  the  greater  the  potential  for
significant adverse impacts to our business operations and those of the CROs, CMOs, commercial collaborators, and other third-party service providers and vendors on
which  we  depend  to,  among  other  things,  conduct  our  clinical  and  nonclinical  studies,  supply  our  clinical  trial  materials,  assist  with  regulatory  affairs  necessary  to
advance and seek regulatory approval for our programs, and market, sell and distribute our products, if approved.

Public  health  emergencies,  natural  or  man  made  disasters,  acts  of  terrorism,  war  or  telecommunications  or  electrical  failures  may  also  have  the  effect  of

heightening many of the other risks and uncertainties described in this “Risk Factors” section.

Product liability lawsuits against us could cause us to incur substantial liabilities.

We face an inherent risk of product liability exposure as a result of testing of our product candidates in human clinical trials and will face an even greater risk
following  commercial  launch  of  a  product  we  develop.  If  we  cannot  successfully  defend  ourselves  against  claims  that  our  products  or  product  candidates  caused
injuries, we will incur substantial liabilities or be required to limit commercialization of our products. Regardless of merit or eventual outcome, liability claims may result
in:

•
•

decreased demand for any marketed product;
product recalls, withdrawals or labeling, marketing or promotional restrictions;

94

termination of product development or commercial collaborations;
loss of revenue;

•
•
• withdrawal of clinical study participants and delays in commencement or completion of clinical studies;
•
•
•
•
•

injury to our reputation and significant negative media attention;
significant costs to defend the related litigation;
substantial monetary awards to patients or clinical study participants;
diversion of our management’s time and other resources from pursuing our business strategy; and
a decline in our stock price.

We carry product liability insurance that we believe to be adequate for our clinical testing and product development programs and in connection with XACIATO.
However, insurance coverage is increasingly expensive, and it may be difficult to obtain adequate product liability insurance in the future. Our inability to obtain and
retain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of any
of our product candidates, if approved. We also have indemnification obligations to our commercial and other collaborators. Although we will endeavor to obtain and
maintain such insurance in coverage amounts we deem adequate, any claim that may be brought against us could result in a court judgment or settlement in an amount
that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies also have various exclusions,
and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement
that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts.

Our  current  or  future  employees,  clinical  investigators,  commercial  collaborators  or  service  providers  may  engage  in  misconduct  or  other  improper
activities, including non-compliance with regulatory standards.

We may become exposed to the risk of employees, clinical investigators, commercial collaborators, CMOs, CROs, consultants or other vendors engaging in
fraud  or  other  misconduct.  Misconduct  by  our  employees  or  third  parties  on  which  we  rely  for  the  development  and  commercialization  of  our  products  and  product
candidates  could  include  intentional  failures,  such  as  failures  to:  (1)  comply  with  FDA  or  other  regulators’  requirements,  (2)  provide  accurate  information  to  such
regulators, (3) comply with clinical and nonclinical research standards and manufacturing standards established by us and/or required by the FDA or other laws and
regulations, or (4) comply with SEC rules and regulations. In particular, sales, marketing and business arrangements in the health care industry are subject to extensive
laws, regulations and industry guidance intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may
restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements.
Misconduct by current or future employees, clinical investigators, commercial collaborators, CROs, consultants or other vendors could also involve the improper use of
information  obtained  in  the  course  of  clinical  trials,  which  could  result  in  regulatory  or  civil  sanctions  and  serious  harm  to  our  reputation.  It  is  not  always  possible  to
identify  and  deter  misconduct  by  these  parties,  and  the  precautions  we  take  to  detect  and  prevent  this  activity  may  not  be  effective  in  controlling  unknown  or
unmanaged  risks  or  losses,  or  in  protecting  us  from  governmental  investigations  or  other  actions  or  lawsuits  stemming  from  a  failure  to  comply  with  such  laws  or
regulations. If any such actions are instituted against us, and we are not successful in defending or asserting our rights, those actions could have a significant adverse
effect on our business, including the imposition of significant fines or other sanctions, and our reputation.

The pharmaceutical and medical device industries are highly regulated and subject to various fraud and abuse laws, including, without limitation, the U.S.
federal Anti-Kickback Statute, the U.S. federal False Claims Act and the U.S. Foreign Corrupt Practices Act.

Health care providers and third-party payors play a primary role in the recommendation and prescription of drug products and medical devices that are granted
marketing  approval.  Our  arrangements  with  health  care  providers,  commercial  collaborators,  principal  investigators,  consultants,  third-party  payors,  customers  and
other  organizations  may  expose  us  to  broadly  applicable  fraud  and  abuse  and  other  health  care  laws  and  regulations  in  the  U.S.  Health  care  fraud  and  abuse
regulations are complex, and even minor irregularities can give rise to claims that a statute or prohibition has been violated. The laws that may affect our operations
include:

•

the  federal  Anti-Kickback  Statute  (and  comparable  state  laws),  which  prohibits,  among  other  things,  any  person  from  knowingly  and  willfully  offering,
providing, soliciting or receiving remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce either the referral of an individual, for an
item  or  service  or  the  purchasing  or  ordering  of  a  good  or  service,  for  which  payment  may  be  made  under  federal  health  care  programs  such  as  the
Medicare  and  Medicaid  programs.  The  federal  Anti-Kickback  Statute  is  subject  to  evolving  interpretations.  In  the  past,  the  government  has  enforced  the
federal Anti-Kickback

95

Statute to reach large settlements with health care companies based on sham consulting and other financial arrangements with physicians. A person or
entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the government
may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for
purposes of the civil False Claims Act;

•

•

•

federal  and  state  civil  and  criminal  false  claims  laws,  including  the  civil  False  Claims  Act  which  prohibit,  among  other  things,  any  person  or  entity  from
knowingly presenting, or causing to be presented, a false, fictitious or fraudulent claim for payment to the U.S. government, knowingly making, using, or
causing to be made or used, a false record or statement material to a false or fraudulent claim to the U.S. government, or from knowingly making a false
statement to avoid, decrease or conceal an obligation to pay money to the U.S. government. Actions under these laws may be brought by the U.S. Attorney
General  or  as  a  qui  tam  action  by  a  private  individual  in  the  name  of  the  government.  The  federal  government  uses  these  laws,  and  the  accompanying
threat  of  significant  liability,  in  its  investigation  and  prosecution  of  pharmaceutical  and  biotechnology  companies  throughout  the  U.S.,  for  example,  in
connection with the promotion of products for unapproved uses and other allegedly unlawful sales and marketing practices;

federal, civil and criminal statues created under HIPAA (and similar state laws), which prohibit, among other actions, knowingly and willfully executing, or
attempting  to  execute,  a  scheme  to  defraud  any  health  care  benefit  program,  including  private  third-party  payors,  knowingly  and  willfully  embezzling  or
stealing  from  a  health  care  benefit  program,  willfully  obstructing  a  criminal  investigation  of  a  health  care  offense,  and  knowingly  and  willfully  falsifying,
concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for
health care benefits, items or services. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute
or specific intent to violate it in order to have committed a violation;

the Physician Payments Sunshine Act, enacted as part of the ACA, which, among other things, imposes reporting requirements on manufacturers of FDA-
approved  drugs,  devices,  biologics  and  medical  supplies  covered  by  Medicare  or  Medicaid  to  report  to  CMS,  on  an  annual  basis,  information  related  to
payments  and  other  transfers  of  value  to  physicians  (defined  broadly  to  include  doctors,  dentists,  optometrists,  podiatrists,  and  chiropractors),  certain
advanced  non-physician  health  care  practitioners,  and  teaching  hospitals,  as  well  as  ownership  and  investment  interests  held  by  physicians  and  their
immediate family members in such manufacturers;

• HIPAA, as amended by HITECH, and their respective implementing regulations, which impose specified requirements relating to the privacy, security and
electronic exchange of individually identifiable health information, or "protected health information" when subject to HIPAA. Among other things, HITECH
makes some of HIPAA’s privacy and all of HIPAA's security standards directly applicable to “business associates,” defined as independent contractors or
agents of covered entities, that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a
covered entity. "Covered entity" or entities that must comply with HIPAA, include certain health care providers, health plans, and health care clearinghouses.
HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and third parties unlawfully in
possession of protected health information, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to
enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions; and

•

the U.S. Foreign Corrupt Practices Act, which prohibits U.S. organizations and their representatives from offering, promising, authorizing or making corrupt
payments, gifts or transfers of value to non-U.S. officials, which in many countries, could include interactions with certain health care professionals.

The scope and enforcement of these laws is uncertain and subject to rapid change in the current environment of health care reform, especially in light of the

lack of applicable precedent and regulations.

The risk of violation of, and subsequent investigation and prosecution for violations of, the laws described above may be mitigated through the implementation
and maintenance of compliance programs by us and our commercial collaborators and other third parties on which we rely for important aspects of development or
commercialization of our products and product candidates, but these risks cannot be eliminated entirely. Ensuring that our current and future business operations and
arrangements with third parties comply with applicable health care laws and regulations could involve substantial costs. It is possible that governmental authorities will
conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or case law involving

96

applicable fraud and abuse or other health care laws and regulations. If we or our operations, or those of a commercial collaborator or other third party on which we rely
for development or commercialization of our products and product candidates, are found to be in violation of any of the laws described above or any other governmental
regulations that apply to us or that third party, we may be subject to significant civil, criminal and administrative penalties, including monetary damages, fines, individual
imprisonment, disgorgement, loss of eligibility to obtain approvals from the FDA, exclusion from participation in government contracting, health care reimbursement or
other government programs, including Medicare and Medicaid, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings,
additional reporting requirements if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with any of these
laws, and/or the curtailment or restructuring of our operations. If any of the physicians or other health care providers or entities with whom we expect to do business is
found  to  be  not  in  compliance  with  applicable  laws,  they  may  be  subject  to  criminal,  civil  or  administrative  sanctions,  including  exclusions  from  government  funded
health care programs.

If  regulatory  authorities  challenge  our  activities,  or  those  of  a  commercial  collaborator  or  other  third  party  on  which  we  rely,  under  these  laws,  any  such
challenge could have a material adverse effect on our reputation, business, results of operations and financial condition. Any investigation of us or the third parties with
whom  we  contract,  including  a  commercial  collaborator,  regardless  of  the  outcome,  would  be  costly  and  time  consuming,  and  may  negatively  affect  our  results  of
operations and financial condition.

Cyber-attacks,  security  breaches,  loss  of  data  and  other  disruptions  to  our  information  technology  systems  or  those  of  our  collaborators  or  third-party
service providers could compromise sensitive information related to our business, delay or prevent us from accessing critical information, subject us to
significant financial loss, and expose us to liability, any of which could adversely affect our business and our reputation.

We  utilize  information  technology  systems  and  networks  in  the  ordinary  course  of  our  business  to  process,  transmit  and  store  sensitive  data,  including
confidential information, intellectual property, and personally identifiable information of our employees, consultants and others. As the use of digital technologies has
increased, cyber incidents, including deliberate attacks (such as the deployment of harmful malware and other malicious code, ransomware, denial of service, social
engineering, and other attempts to gain unauthorized access to computer systems and networks), have increased in frequency and sophistication, and have become
increasingly difficult to detect. These threats pose a risk to the security of our systems and networks and those of our collaborators and third-party service providers,
which  store  sensitive  data  of  ours,  and  could  compromise  the  confidentiality,  availability  and  integrity  of  information  stored  there  which  is  vital  to  our  operations  and
business  strategy.  A  successful  cyber-attack  could  cause  serious  negative  consequences  for  us,  including,  without  limitation,  the  disruption  of  our  operations,  the
misappropriation or destruction of our confidential information and sensitive data, including clinical trial data, corporate strategic plans and financial information, and the
misappropriation  of  other  assets,  including  our  cash.  Organizations  and  governmental  bodies  with  far  greater  resources  than  ours  dedicated  to  cybersecurity  have
proven vulnerable to cyber-attacks. There can be no assurance we will succeed in preventing cybersecurity breaches or successfully mitigate their effects. In March
2023, we became aware that we had been subject to a criminal fraud commonly referred to as “business email compromise fraud.” The incident involved unauthorized
access to an employee’s email account by a third-party impersonator and resulted in an electronic payment of approximately $0.4 million intended for a vendor being
fraudulently misdirected to unknown parties. We retained a third party to assist in our investigation of the incident and implementation of remedial measures, including
enhancements to our controls relating to electronic payments to third parties. Approximately $0.2 million of the fraud loss was covered by insurance. We do not believe
this incident had or will have a material impact on our business, financial condition or results of operations. However, cyber-related criminal activities continue to evolve
and  increase  in  frequency  and  sophistication,  including  as  a  result  of  advancements  in  generative  artificial  intelligence  technology,  and  our  security  measures  and
controls may not be successful in preventing further cyber-related crimes.

Despite implementing security measures, any of the information technology systems belonging to us or our collaborators and third-party service providers and
the  sensitive  and  confidential  information  contained  within  them  are  vulnerable  to  damage  or  interruption  from  computer  viruses  and  other  malware,  unauthorized
access,  including  as  a  result  of  employee  error  (e.g.,  phishing  or  spoofing  scams)  or  malfeasance,  service  interruptions,  system  malfunctions,  natural  disasters,
terrorism,  war,  and  telecommunication  and  electrical  failure.  We  rely  on  third-party  service  providers  and  technologies  for  our  data  processing-related  activities,
including without limitation third-party providers of cloud-based infrastructure, encryption and authentication technology, employee email, and other functions. Our ability
to monitor these third parties' cybersecurity practices is limited, and these third parties may not have adequate information security measures in place. In addition, we
do  not  have  our  own  information  technology  department  or  personnel  and  rely  on  third-party  consultants  and  other  service  providers  to  establish  and  maintain  our
information technology infrastructure and systems, and they may fail to perform as expected. Moreover, the shift to remote working arrangements and the prevalent use
of mobile devices that access sensitive or confidential

97

information increases the risk of data security breaches. Technology security systems and other security measures in employees’ homes or other places they may work
may not be as robust and more vulnerable to cybersecurity attacks. Any system failure, accident, security breach or data breach that causes interruptions in our own or
in third-party collaborators’ or service providers’ operations could result in unauthorized, unlawful, or accidental acquisition, modification, destruction, loss, alteration,
encryption, disclosure of, or access to our sensitive or confidential information. A security incident or other interruption could disrupt our ability (or that of third parties
upon  which  we  rely)  to  conduct  our  business  operations  and  could  divert  significant  resources  to  remedy  or  mitigate  the  damage  caused.  For  example,  if  clinical  or
nonclinical study data is lost or becomes compromised, it could result in delays in our product development and regulatory approval efforts and significantly increase our
costs due to additional time and resources necessary to recover and verify, or potentially reproduce, the data. In addition, a security breach or privacy violation that
leads  to  disclosure  of  personally  identifiable  information  or  protected  health  information  could  require  us  to  make  notifications  to  the  public  as  well  as  regulatory
authorities, harm our reputation, subject us to audit, investigation, steep fines and administrative penalties and mandatory corrective action. A data breach could also
require us to verify the correctness of database contents and subject us to litigation, including class action lawsuits, or other liability under laws and regulations that
protect personal data, consumer protection and other laws. Further, our information technology and other internal infrastructure systems, including firewalls, servers,
leased lines and connection to the internet, face the risk of systemic failure, which could disrupt our operations. If any disruption or security breach results in a loss or
damage  to  our  data  or  applications,  or  inappropriate  disclosure  of  confidential  or  proprietary  information,  we  may  incur  resulting  liability,  our  product  development
programs and competitive position may be adversely affected, the further development of our product candidates may be delayed, and the manufacture and sale of any
approved products may be impaired.

The costs related to significant security breaches or disruptions could be material, and, as was the case with the fraud discovered in March 2023, our insurance
coverage  may  not  cover  all  the  losses  arising  from  any  such  disruption  in,  or  failure  or  security  breach  of,  our  systems  or  third-party  systems  where  information
important  to  our  business  operations  and  product  development  is  stored  or  processed.  In  addition,  such  insurance  may  not  be  available  to  us  in  the  future  on
economically reasonable terms, or at all. Further, our insurance may not cover all claims made against us and could have high deductibles in any event, and defending
a suit, regardless of its merit, could be costly and divert management attention. Moreover, if the information technology systems of our third-party collaborators, service
providers  or  vendors  become  subject  to  disruptions  or  security  breaches,  we  may  have  insufficient  recourse  against  such  third  parties  and  we  may  have  to  expend
significant resources to mitigate the impact of such an event.

Our business may be adversely affected by unfavorable or unanticipated macroeconomic conditions and geopolitical events.

Various macroeconomic factors could adversely affect our business, our results of operations and financial condition, including a U.S. government shutdown,
delay  or  failure  of  the  U.S.  government  to  raise  the  federal  debt  ceiling,  an  increased  rate  of  inflation,  rising  interest  rates,  adverse  developments  affecting  financial
institutions  or  the  financial  services  industry,  recessionary  concerns  and  overall  unfavorable  economic  conditions  and  uncertainties,  including  those  resulting  from
geopolitical events, including the wars in Ukraine and the Middle East and strained relations between the U.S. and a number of foreign countries; international economic
sanctions, including those imposed on Russia; climate change concerns; or public health emergencies, including the COVID-19 pandemic. U.S. government actions to
reduce the federal deficit, or its delay or failure to raise the federal debt ceiling, may result in reduced funding for government-funded or subsidized health programs or
require the federal government to stop or delay making payments on its obligations under such programs, which could impact sales of our products covered under such
programs, if any, and negatively affect our operating results. Interest rates and the ability to access credit markets could adversely affect the ability of patients, payors
and  distributors  to  purchase,  pay  for  and  effectively  distribute  our  products,  if  and  when  approved.  Similarly,  unfavorable  or  uncertain  macroeconomic  factors  could
affect  the  ability  of  our  current  or  potential  future  collaborators,  third-party  service  providers  or  suppliers,  including  sole  source  or  single  source  manufacturers  or
suppliers, licensors or licensees to remain in business, or otherwise manufacture or supply our clinical trial material and products or commercialize our products, if and
when approved. Failure by any of them to remain in business or allocate adequate resources to our products and product candidates could have a material adverse
effect on our efforts to develop and obtain regulatory approvals for our product candidates and generate revenue from any approved products.

We expect to continue to incur substantial costs and demands on management time to comply with laws and regulations affecting public companies.

We incur and expect to continue to incur significant legal, accounting and other expenses as a public reporting company. We expect that these expenses will
increase if and when we become an “accelerated filer,” as defined in rules adopted by the SEC under the Securities Exchange Act of 1934. Generally, we will become
an

98

accelerated filer if our public float as of the last business day of June is $75 million or more and we reported annual revenues of $100 million or more for our most
recently  completed  fiscal  year.  Regardless  of  whether  we  become  an  accelerated  filer,  we  may  need  to  hire  additional  accounting,  finance  and  other  personnel  in
connection  with  our  continuing  efforts  to  comply  with  the  corporate  governance,  disclosure  and  other  reporting  requirements  of  being  a  public  company,  and  our
management and other personnel, of whom we have a small number, will need to continue to devote substantial time towards compliance matters and initiatives.

For example, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we must furnish a report annually by our management on the effectiveness of our
internal  control  over  financial  reporting,  and  performing  the  system  and  process  documentation  and  evaluation  necessary  to  issue  that  report  requires  us  to  incur
substantial expense and expend significant management time. If and when we are an accelerated filer, we will also have to obtain an attestation report on our internal
control  over  financial  reporting  by  our  independent  registered  public  accounting  firm,  which  may  substantially  increase  compliance  costs.  Recent  SEC  rules  and
rulemaking initiatives, such as the new pay versus performance, cybersecurity, and climate-related disclosure requirements, may result in significant additional time and
expense devoted to compliance initiatives.

We are a smaller reporting company and a non-accelerated filer and the reduced disclosure requirements available to us may make our common stock less
attractive to investors.

The SEC established the smaller reporting company, or SRC, category of companies in 2008, and expanded it in 2018, in an effort to provide general regulatory
relief  for  smaller  companies.  SRCs  may  choose  to  comply  with  scaled  financial  and  non-financial  disclosure  requirements  in  their  annual  and  quarterly  reports  and
registration  statements  relative  to  non-SRCs.  In  addition,  companies  that  are  not  “accelerated  filers”  can  take  advantage  of  additional  regulatory  relief.  Whether  a
company is an accelerated filer or a SRC is determined on an annual basis. For so long as we qualify as a non-accelerated filer and/or an SRC, we will be permitted to
and we intend to rely on some or all of the accommodations available to such companies. These accommodations include:

•

•

•

•

not being required to provide an auditor’s attestation of management’s assessment of internal control over financial reporting required by Section 404(b) of
the Sarbanes-Oxley Act of 2002;

reduced financial disclosure obligations, including that SRCs need only provide two years of financial statements rather than three years; a maximum of two
years of acquiree financial statements are required rather than three years; fewer circumstances under which pro forma financial statements are required;
and less stringent age of financial statements requirements;

reduced  non-financial  disclosure  obligations,  including  regarding  the  description  of  their  business,  management’s  discussion  and  analysis  of  financial
condition and results of operations, market risk, executive compensation, transactions with related persons, and corporate governance; and

later deadlines for the filing of annual and quarterly reports compared to accelerated filers.

We will continue to qualify as a SRC and non-accelerated filer for so long as (a) our public float is less than $75 million as of the last day of our most recently
completed second fiscal quarter or (b) our public float is $75 million or more but less than $700 million and we reported annual revenues of less than $100 million for our
most recently completed fiscal year.

We may choose to take advantage of some, but not all, of the available accommodations. We cannot predict whether investors will find our common stock less
attractive if we rely on these accommodations. If some investors find our common stock less attractive as a result, there may be a less active trading market for our
common stock and the price of our common stock may be more volatile.

Our ability to use net operating loss carryforwards and other tax attributes to offset taxable income may be limited.

We have incurred substantial losses during our history, do not expect to become profitable in the near future and may never achieve profitability. To the extent
that  we  continue  to  generate  taxable  losses,  unused  losses  will  carry  forward  to  offset  future  taxable  income,  if  any,  until  such  unused  losses  expire,  if  at  all.  At
December 31, 2023, we had substantial federal and state net operating loss, or NOL, carryforwards. However, our federal NOL carryforwards and other tax attributes
may  not  be  available  to  offset  future  taxable  income  because  of  restrictions  under  U.S.  tax  law,  and  similar  limitations  may  apply  under  state  tax  laws.  We  have
recorded a full valuation allowance related to our NOL carryforwards and other deferred tax assets due to the uncertainty of the ultimate realization of the future benefits
of those assets. See Note 7 “Income Taxes” to the accompanying consolidated financial statements for more information

99

about limitations on our ability to use our NOL carryforwards and other tax attributes. Such limitations could result in increased future income tax liability to us and our
future cash flows could be adversely affected.

An extended curtailment or halt of operations at the FDA, NIH, SEC and other government agencies, including due to a U.S. federal government shutdown,
could delay or disrupt clinical and preclinical development and potential marketing approval of our product candidates and our ability to raise additional
capital.

Twice  in  the  past  decade,  the  previous  appropriations  legislation  deadline  was  reached  and  Congress  failed  to  pass  a  new  appropriations  bill  or  continuing
resolution to temporarily extend funding, resulting in U.S. government shutdowns that caused federal agencies to halt non-essential operations. The federal government
came  very  close  to  another  shutdown  in  late  2023.  Political  polarization  among  lawmakers  may  lead  to  a  higher  frequency  and  longer  duration  of  government
shutdowns in the future. A federal government shutdown could prevent staff at federal agencies from performing key functions that may adversely affect our business.
For example, disruptions at the FDA may delay meetings and other communications with agency staff necessary to progress development of our product candidates
and may slow the time necessary for acceptance, review and approval of applications to commence clinical studies or to market a new product in the U.S. By way of
further example, disruptions at the NIH, including its various institutes and centers, such as NICHD, could delay processing of new grant awards to fund research and
development of potential new therapies or the disrupt staff’s work and other activities or funding under active grant/cooperative agreements. If a prolonged government
shutdown were to occur while our Phase 3 clinical study of Ovaprene is ongoing, depending on the amount of funds allocated and made available to the study before
the shutdown begins, a federal government shutdown could adversely impact the ability of NICHD to carry out its responsibilities under our CRADA, including funding
its share of the costs of the study, which could have a material adverse impact on our business and prospects. In addition, a government shutdown could prevent SEC
staff from performing key functions, including, for example, granting acceleration requests for registration statements, declaring registration statements or amendments
thereto  effective  and  providing  interpretive  guidance  or  no-action  letters.  While  we  currently  have  an  effective  shelf  registration  statement  on  Form  S-3,  a  shelf
registration  statement  on  Form  S-3  typically  can  only  be  used  for  three  years,  subject  to  a  limited  extension,  and  that  three-year  period  for  our  current  shelf  S-3
registration statement ends on April 7, 2024. If a federal government shutdown halts non-essential SEC operations for an extended period, it may negatively impact our
ability to raise additional capital through registered offerings of our securities in the future. If a prolonged U.S. government shutdown or other event or condition occurs
that prevents the FDA, NIH, SEC or other regulatory agencies from hiring and retaining personnel and conducting their regular activities, it could significantly impact the
ability of these agencies to timely review and process our regulatory submissions and may impede our access to additional capital needed to maintain or expand our
operations or to complete important acquisitions or other transactions, which could have a material adverse effect on our business.

Risks Related to Ownership of Our Common Stock

The  price  of  our  common  stock  may  rise  and  fall  rapidly,  substantial  price  fluctuations  may  occur  regardless  of  developments  in  our  business  or  our
operating performance, and you could lose all or part of your investment as a result.

The  stock  market  in  general,  and  the  market  for  biopharmaceutical  companies  in  particular,  have  experienced  significant  volatility,  which  has  often  been
unrelated to the operating performance of particular companies. The stocks of small cap and microcap biopharmaceutical companies like ours tend to be highly volatile.
Our common stock has experienced extreme trading price and volume fluctuations in the past, including fluctuations that have been unrelated or disproportionate to
developments in our business and our operating performance, and we expect that our stock price will continue to experience high volatility. The market price for our
common stock may be influenced by a variety of factors, some of which are beyond our control or are related in complex ways, including:

•

•

•

significant developments with our product development programs, such as actual or anticipated changes to development and approval timelines, results
from any clinical trial, unanticipated serious safety concerns, suspension or discontinuation of a program, initiation of new programs and communications or
decisions from the FDA or other regulatory authorities relating to applications we submit for clinical trials or marketing approval of our product candidates, in
each case particularly those related to our clinical-stage product candidates;

announcements of capital raising transactions, including sales of our common stock or securities convertible into or exercisable for shares of our common
stock by us, or expectation of additional financing efforts;

the amount of our unrestricted cash;

100

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the level of actual or anticipated expenses related to development of our product candidates, and in particular our clinical-stage development programs;

announcements relating to strategic collaborations or alliances or significant licenses, acquisitions or dispositions of assets by us or companies perceived to
be comparable to us;

disputes  or  other  developments  relating  to  proprietary  rights,  including  patents,  litigation  matters  and  our  ability  to  obtain  patent  protection  for  our
technologies;

announcements by us or our competitors of significant acquisitions, strategic collaborations, joint ventures and capital commitments;

additions or departures of key management or scientific personnel;

significant  developments  with  third-party  products  or  product  development  programs  perceived  as  competitive  to  ours,  such  as  results  of  clinical  trials,
unanticipated  serious  safety  concerns,  suspension  or  discontinuation  of  a  program,  significant  communications  or  decisions  from  the  FDA  or  other
regulatory authorities, introduction of new product candidates or new uses for existing products, commercial launch and product sales;

significant business disruptions, including as a result of cybersecurity incidents, geopolitical events, including military conflicts, war, terrorism or economic
conflicts, or natural disasters such as earthquakes, typhoons, floods and fires or public health emergencies such as the COVID-19 pandemic;

events  or  conditions  that  affect  the  financial  markets  or  U.S.  or  global  economy  in  general,  including  geopolitical  conflicts,  potential  or  actual  U.S.
government shutdown or failure to raise the federal debt ceiling, economic slowdown or recession, increased inflation, and rising interest rates;

regulatory or legal developments in the U.S. and other countries;

changes in the structure of health care payment systems;

developments or trends in the biopharmaceutical or women's health care industries;

period to period fluctuations in our financial results;

recommendations or reports issued by securities research analysts;

increased selling by our stockholders, as well as the overall trading volume of our common stock; and

the other factors described in this “Risk Factors” section.

In the past, following periods of volatility in companies’ stock prices, securities class-action litigation has often been instituted against such companies. Such
litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which could materially and adversely affect
our business and financial condition.

If we fail to regain and maintain compliance with the continued listing requirements of the Nasdaq Capital Market, our common stock could be suspended
and delisted, which could, among other things, limit demand for our common stock, substantially impair our ability to raise additional capital and have an
adverse effect on the market price of, and the efficiency of the trading market for, our common stock.

Our  common  stock  is  listed  on  The  Nasdaq  Capital  Market.  As  previously  reported,  on  July  19,  2023,  we  received  a  letter  from  the  Listing  Qualifications
Department  (the  “Nasdaq  Staff”)  of  the  Nasdaq  Stock  Market  (“Nasdaq”)  notifying  us  that,  for  the  last  30  consecutive  business  days,  the  closing  bid  price  for  our
common stock was below the minimum $1.00 per share requirement for continued listing on The Nasdaq Capital Market as set forth in Nasdaq Listing Rule 5550(a)(2)
(the “Minimum Bid Price Requirement”). We were provided an initial period of 180 calendar days, or until January 16, 2024, to regain compliance with the Minimum Bid
Price Requirement. On January 17, 2024, the Nasdaq Staff notified us that because we had not timely regained compliance with the Minimum Bid Price Requirement,
our common stock was subject to delisting from The Nasdaq Capital Market unless we timely requested a hearing before Nasdaq’s Hearings Panel (the “Panel”) to
appeal  the  Nasdaq  Staff’s  delisting  determination.  We  submitted  a  timely  request  for  a  hearing  before  the  Panel,  which  stayed  the  suspension  and  delisting  of  our
common stock pending the decision of the Panel and the expiration of any extension period granted by the Panel.

On  February  27,  2024,  the  Panel  notified  us  that,  based  on  its  review  of  the  written  record,  which  included  our  commitment  to  effect  a  reverse  stock  split  if
necessary to regain compliance with the Minimum Bid Price Requirement, it determined to grant us a temporary exception until July 15, 2024 (the “Exception Period”) to
regain  compliance  with  the  Minimum  Bid  Price  Requirement.  The  Panel  granted  the  temporary  exception  subject  to  us  obtaining  board  of  directors  and  stockholder
approval for and effecting the reverse stock split on or before specified dates that would enable us to demonstrate compliance with the Minimum Bid Price Requirement
by evidencing a closing bid price of $1.00 or more per share for a minimum of ten consecutive trading sessions on or before July 15, 2024. The Panel

101

advised us that, during the Exception Period, we must provide Nasdaq with prompt notification of any significant events that may affect our compliance with Nasdaq
listing requirements, including any event that may call into question our ability to meet the terms of the temporary exception. The Panel also advised us that should we
fail to meet any of the terms of the temporary exception, our common stock will immediately be delisted.

As of the date of this report, we have not regained compliance with the Minimum Bid Price Requirement. If we seek stockholder approval of a reverse stock
split, there can be no assurance that our stockholders will approve it or, if approved and implemented, that we would be able to regain compliance with the Minimum Bid
Price  Requirement.  There  are  many  factors  that  affect  the  trading  price  of  our  common  stock,  including  those  described  in  this  “Risk  Factors”  section,  and  many  of
those factors are outside of our control. Even if we demonstrate compliance with the Minimum Bid Price Requirement within the Exception Period, a reverse stock split
may not result in any sustained increase in the trading price of our common stock and, as a result, we may not be able to maintain compliance with the Minimum Bid
Price Requirement longer term.

There  can  be  no  assurance  we  will  be  able  to  satisfy  all  other  continued  listing  requirements  of  the  Nasdaq  Capital  Market  and  maintain  the  listing  of  our
common stock on the Nasdaq Capital Market even if we regain compliance with the Minimum Bid Price Requirement. Other continued listing requirements include that
we satisfy the requirements of at least one of the continued listing standards commonly referred to as the stockholders’ equity rule, the market value of listed securities
rule  and  the  net  income  rule.  The  stockholders’  equity  rule  requires  that  our  stockholders’  equity  be  at  least  $2.5  million,  the  market  value  of  listed  securities  rule
requires that the market value of our common stock be at least $35 million, and the net income rule requires that we have net income from continuing operations of
$500,000 in our most recently completed fiscal year or in two of our three most recently completed fiscal years. Based on our stockholders’ equity as of December 31,
2023 and our results of operations for our three most recently completed fiscal years, we do not satisfy the stockholders’ equity rule or the net income rule. As of March
27, 2024, we did satisfy the market value of listed securities rule.

The  suspension  or  delisting  of  our  common  stock,  for  whatever  reason,  could,  among  other  things,  substantially  impair  our  ability  to  raise  additional  capital;
result  in  the  loss  of  interest  from  institutional  investors,  the  loss  of  confidence  in  our  company  by  investors  and  employees,  and  in  fewer  financing,  strategic  and
business development opportunities; and result in potential breaches of agreements under which we made representations or covenants relating to our compliance with
applicable  listing  requirements.  Claims  related  to  any  such  breaches,  with  or  without  merit,  could  result  in  costly  litigation,  significant  liabilities  and  diversion  of  our
management’s time and attention and could have a material adverse effect on our financial condition, business and results of operations. In addition, the suspension or
delisting  of  our  common  stock,  for  whatever  reason,  may  materially  impair  our  stockholders’  ability  to  buy  and  sell  shares  of  our  common  stock  and  could  have  an
adverse effect on the market price of, and the efficiency of the trading market for, our common stock.

A reverse stock split could lead to a decrease in the overall market value of our common stock and adversely affect the liquidity of our common stock.

A reverse stock split, if implemented, would reduce the number of outstanding shares of our common stock in proportion to the reverse split ratio and would
have the immediate effect of proportionately increasing the per share price of our common stock. A reverse stock split is often viewed negatively by the market and,
consequently, could lead to a decrease in our overall market value. If the per share trading price of our common stock does not increase in proportion to the reverse
stock split ratio after the reverse stock split is implemented, then our overall market value (measured as the product of our outstanding shares of common stock and the
per share trading price) will be less than before the reverse stock split. In some cases, the per share stock price of companies that have effected reverse stock splits
subsequently declined back to pre-reverse stock split levels. Accordingly, if we implement a reverse stock split, there can be no assurance that our overall market value
will remain the same after the reverse stock split, or that the reverse stock split would not have an adverse effect on the trading price of our common stock due to the
reduced number of shares that would be outstanding after the reverse stock split. Liquidity for our stockholders could be adversely affected by the reduced number of
shares outstanding after a reverse stock split. A reduction in the number of outstanding shares may lead to reduced trading and a smaller number of market makers for
our common stock. In addition, a reverse stock split may result in some stockholders owning “odd lots” of less than 100 shares. Odd lot shares may be more difficult to
sell,  and  brokerage  commissions  and  other  costs  of  transactions  in  odd  lots  are  generally  somewhat  higher  than  the  costs  of  transactions  in  “round  lots”  of  even
multiples of 100 shares.

102

The sale of our common stock in ATM offerings may cause substantial dilution to our existing stockholders, and such sales, or the anticipation of such
sales, may cause the price of our common stock to decline.

We have used at-the-market, or ATM, offerings to fund a significant portion of our operations in recent years, and we may continue to use ATM offerings to raise
additional  capital  in  the  future.  For  example,  in  2021,  we  sold  an  aggregate  of  approximately  36.4  million  shares  of  our  common  stock  in  ATM  offerings.  We  sold
substantially fewer shares in ATM offerings in 2022 and 2023, however, we may sell significant amounts of shares in ATM offerings again in the future. While sales of
shares of our common stock in ATM offerings may enable us to raise capital at a lower cost compared with other types of equity financing transactions; such sales may
result in substantial dilution to our existing stockholders, and such sales, or the anticipation of such sales, may cause the trading price of our common stock to decline.

The exercise of our outstanding warrants and options as well as the issuance of shares pursuant to future equity awards under our stock incentive plan
may result in significant dilution to our stockholders.

As  of  December  31,  2023,  we  had  outstanding  warrants  to  purchase  up  to  approximately  15.0  million  shares  of  our  common  stock  at  a  weighted  average
exercise price of $0.63 per share, outstanding options to purchase up to approximately 9.5 million shares of our common stock at a weighted average exercise price of
$1.46 per share and approximately 6.7 million shares of our common stock remained available for future issuance under our stock incentive plan. The exercise of a
significant portion of our outstanding warrants and options and the issuance of shares of our common stock pursuant to future equity awards under our stock incentive
plan may result in significant dilution to our stockholders.

Substantial  future  sales  of  our  shares  of  common  stock,  or  the  perception  that  such  sales  could  occur,  may  cause  the  price  of  our  common  stock  to
decline, even if our business is doing well.

Sales of substantial amounts of our common stock in the public market, or the perception that such sales could occur, may adversely affect the trading price of
our common stock, and may make it more difficult for existing stockholders to sell their shares of our common stock at a time and price they deem appropriate. We are
unable to predict the effect that such sales may have on the trading price of our common stock. These sales, or the possibility that these sales may occur, also might
make it more difficult for us to sell equity or equity-linked securities in the future at a time and at a price that we deem appropriate.

Shares  underlying  outstanding  warrants  represent  approximately  15.0%  of  the  outstanding  shares  of  our  common  stock  as  of  March  27,  2024,  and  the
underlying shares generally may be freely sold into the public market following exercise of the warrants by the warrant holders. In addition, pursuant to the terms of the
royalty  interest  financing  agreement  we  entered  into  in  December  2023,  we  may  issue  additional  warrants  to  purchase  up  to  an  additional  7.0  million  shares  of  our
common  stock  with  an  exercise  price  of  $0.3467  per  share.  Further,  the  issuance  of  all  of  the  approximately  9.5  million  shares  of  our  common  stock  underlying
outstanding  options  and  the  approximately  6.7  million  shares  of  our  common  stock  that  remained  available  for  future  issuance  under  our  stock  incentive  plan  as  of
December 31, 2023 have been registered under the Securities Act and such shares if, and when issued, can be freely sold in the public market, except to the extent
they are held by an affiliate of ours, in which case such shares will become eligible for sale in the public market as permitted by Rule 144 under the Securities Act.

Almost all of our outstanding warrants have exercise periods that extend into December 2028 or March 2029 and, as of December 31, 2023, our outstanding
options  had  a  weighted  average  remaining  contractual  exercise  period  of  approximately  7.5  years.  Accordingly,  the  potential  adverse  market  and  price  pressures
resulting from these sales, or the perception that such sales could occur, may continue for an extended period of time and continued negative pressure on the trading
price of our common stock could have a material adverse effect on our ability to raise additional capital through equity or equity-linked financings. If, in the future, we
issue additional shares of common stock, warrants or other equity or equity-linked securities in one or more transactions, at prices and in a manner we determine from
time to time, in connection with a financing, acquisition, litigation settlement, employee arrangements or otherwise, any such issuance could result in substantial dilution
to our existing stockholders and could cause the price of our common stock to decline.

103

We may issue preferred stock with terms that could dilute the voting power or reduce the value of our common stock.

Our certificate of incorporation authorizes us to issue, without stockholder approval, one or more series of preferred stock having such designation, powers,
privileges, preferences, including preferences over our common stock respecting dividends and distributions, terms of redemption and relative participation, optional, or
other  rights,  if  any,  of  the  shares  of  each  such  series  of  preferred  stock  and  any  qualifications,  limitations  or  restrictions  thereof,  as  our  board  of  directors  may
determine. The terms of one or more series of preferred stock could dilute the voting power or reduce the value of our common stock. For example, the repurchase or
redemption rights or liquidation preferences we could assign to holders of preferred stock could affect the residual value of our common stock.

We do not anticipate paying any cash dividends on our common stock in the foreseeable future; capital appreciation, if any, will be your sole source of gain
as a holder of our shares.

We have never declared or paid cash dividends on any shares of our capital stock. We currently plan to retain all of our future earnings, if any, and all cash
received  from  the  sale  of  securities,  the  sale  of  assets  or  a  strategic  transaction  to  finance  the  growth  and  development  of  our  business.  Accordingly,  capital
appreciation, if any, of our common stock will be the sole source of gain for our common stockholders for the foreseeable future.

Provisions  in  our  certificate  of  incorporation,  our  by-laws  or  Delaware  law  might  discourage,  delay  or  prevent  a  change  in  control  of  our  company  or
changes in our management and, therefore, depress the trading price of our common stock.

Provisions  in  our  Restated  Certificate  of  Incorporation,  as  amended,  our  Third  Amended  and  Restated  By-Laws  or  Delaware  law  may  discourage,  delay  or
prevent a merger, acquisition or other change in control that our stockholders may consider favorable, including transactions in which our stockholders might otherwise
receive  a  premium  for  their  shares.  These  provisions  could  also  limit  the  price  that  investors  might  be  willing  to  pay  in  the  future  for  shares  of  our  common  stock,
thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management
team,  these  provisions  might  frustrate  or  prevent  any  attempts  by  our  stockholders  to  replace  or  remove  the  current  management  by  making  it  more  difficult  for
stockholders to replace members of our board of directors. Among other things, these provisions:

•

•

•

•

•

•

•

•

establish a classified board of directors such that all members of the board are not elected at one time;

allow the authorized number of directors to be changed only by resolution of the board of directors;

limit the manner in which stockholders can remove directors from the board;

establish advance notice requirements for nominations for election to the board or for proposing matters that can be acted on at stockholder meetings;

require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by stockholders by written consent;

limit who may call a special meeting of stockholders;

authorize the board to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that would work to dilute the stock
ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by the board; and

require the approval of the holders of at least 75% of the votes that all stockholders would be entitled to cast in any annual election of directors or class of
directors to amend or repeal our by-laws or certain provisions of our charter.

In addition, we are governed by Section 203 of the Delaware General Corporate Law, which prohibits a publicly-held Delaware corporation from engaging in a
business  combination  with  an  interested  stockholder,  generally  a  person  which  together  with  its  affiliates  owns,  or  within  the  last  three  years  has  owned,  15%  of  its
voting  stock,  for  a  period  of  three  years  after  the  date  of  the  transaction  in  which  the  person  became  an  interested  stockholder,  unless  the  business  combination  is
approved in a prescribed manner. This could discourage, delay or prevent someone from acquiring or merging with us, whether or not it is desired by, or beneficial to,
our stockholders.

Provisions  in  our  by-laws  could  limit  our  stockholders’  ability  to  obtain  a  favorable  judicial  forum  for  disputes  with  us  or  our  directors,  officers  or
employees.

Our Third Amended and Restated By-Laws provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by
law, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for most legal actions involving actions brought against us by stockholders;
provided that, the exclusive forum provision will not apply to actions or suits brought to enforce any liability or duty created by the

104

Securities  Act,  the  Exchange  Act,  or  any  other  claim  for  which  the  federal  courts  have  exclusive  jurisdiction.  If  any  action  that  is  required  under  our  by-laws  to  be
brought against us in Delaware is filed by a stockholder in a court other than a court located within Delaware, the stockholder shall be deemed to have consented to (i)
the personal jurisdiction of the state and federal courts located within Delaware in connection with any action brought in any such court to enforce our Delaware forum
selection provision and (ii) having service of process made upon the stockholder in any such enforcement action by service upon that stockholder's counsel, as agent
for the stockholder. In addition, our by-laws provide that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the
federal district courts of the United States of America shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under
the Securities Act. Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and to have consented
to these provisions.

Under the Securities Act, federal and state courts have concurrent jurisdiction over all suits brought to enforce any duty or liability created by the Securities Act.
We believe the forum selection provisions in our by-laws may benefit us by providing increased consistency in the application of Delaware law and federal securities
laws by chancellors and judges, as applicable, particularly experienced in resolving corporate disputes, efficient administration of cases on a more expedited schedule
relative to other forums and protection against the burdens of multi-forum litigation. However, these provisions may have the effect of discouraging lawsuits against us
and/or our directors, officers and employees as it may limit any stockholder’s ability to bring a claim in a judicial forum that such stockholder finds favorable for disputes
with us or our directors, officers or employees. The enforceability of similar choice of forum provisions in other companies’ charter documents has been challenged in
legal proceedings, and it is possible that, in connection with any applicable action brought against us, a future court could find the choice of forum provisions contained
in our by-laws to be inapplicable or unenforceable in such action. If a court were to find the choice of forum provision contained in our by-laws to be inapplicable or
unenforceable  in  an  action,  we  may  incur  additional  costs  associated  with  resolving  such  action  in  other  jurisdictions,  which  could  adversely  affect  our  business,
financial condition or results of operations.

If we fail to attract or maintain securities analysts to publish research on our business or if they publish or convey negative evaluations of our business, the
price of our stock could decline.

The trading market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our business. We do
not have any control over these analysts. If one or more of the analysts covering our business downgrade their evaluations of our stock, the price of our common stock
could  decline.  As  of  the  date  of  this  report,  to  our  knowledge,  five  analysts  cover  our  company.  If  one  or  more  of  these  analysts  cease  coverage  or  fail  to  regularly
publish reports on our business, we could lose visibility in the financial markets, which in turn could cause our common stock price or trading volume to decline.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

As is the case for other companies in our industry, we may be the target of cyberattacks and other cyber incidents and, therefore, cybersecurity is an important
element of our overall enterprise risk management, or ERM, program. Our management performs a semi-annual assessment of enterprise-wide risks to help assess,
identify,  and  manage  existing  and  emerging  risks  for  our  company,  including  cybersecurity  risks.  Through  our  ERM  program  we  assess  the  characteristics  and
circumstances of the evolving business environment at the time and seek to identify the potential impacts to our company of a particular risk.

Primary  responsibility  for  assessing,  identifying,  and  managing  our  cybersecurity  risks  rests  with  our  management.  To  assist  our  management  with  such
responsibility, we engage and consult with an external third party information technology consultant who reports to our Chief Accounting Officer. We also perform an
annual  cybersecurity  assessment  designed  to  help  improve  the  systems  and  processes  we  have  implemented  designed  to  safeguard  our  information  assets  and
operational integrity from cyber threats, protect employee information from unauthorized access or attack, as well as secure our networks and systems. Network and
information systems and other technologies, including those related to our network management, are important to our business activities. As a result, we have multiple
layers  of  security  designed  to  detect  and  deter  cybersecurity  incidents.  As  part  of  our  overall  ERM  program,  we  monitor  and  test  our  safeguards  and  train  our
employees on these safeguards, in certain instances with the assistance of our external third party information technology consultant. Personnel at all levels and

105

departments  are  made  aware  of  our  cybersecurity  policies  through  trainings.  We  also  maintain  an  incident  response  plan  designed  to  respond  to,  mitigate  and
remediate cybersecurity incidents according to a defined set of severity ratings based on the potential impact to our business, information technology systems, network
or data, including data held or information technology services provided by third-party vendors or other service providers.

As  of  the  date  of  filing  this  report,  we  do  not  believe  there  are  any  risks  from  cybersecurity  threats  that  have  materially  affected  or  are  reasonably  likely  to

materially affect us or our business strategy, results of operations or financial condition.

For additional information regarding risks from cybersecurity threats, please refer to Item 1A, “Risk Factors,” in this annual report on Form 10-K.

Governance

Our board of directors administers its cybersecurity risk oversight function through its audit committee. The audit committee is responsible for overseeing our
policies,  practices  and  assessments  with  respect  to  cybersecurity,  and  provides  periodic  updates  to  our  board  of  directors.  The  audit  committee  receives  periodic
updates  from  management  and  our  external  third  party  information  technology  consultant  regarding  the  effectiveness  of  the  systems  and  processes  we  have
implemented  designed  to  safeguard  our  information  assets  and  operational  integrity  from  cyber  threats,  protect  employee  information  from  unauthorized  access  or
attack, as well as secure our networks and systems, and regarding other cybersecurity matters, including the results from cybersecurity systems testing and any recent
cybersecurity  incidents  and  related  responses.  Our  audit  committee  is  also  notified  between  such  updates  as  soon  as  practicable  regarding  significant  new
cybersecurity threats or incidents. The audit committee also receives a report on cybersecurity matters and related risk exposures at least semi-annually from our Chief
Accounting  Officer.  Many  of  our  board  members  have  achieved  the  National  Association  of  Corporate  Directors  Carnegie  Mellon  University  CERT  Certification  in
Cybersecurity Oversight.

ITEM 2. PROPERTIES

We lease real property to support our business. We believe that the real property we lease is in good operating condition, meets our current needs and that we
will  be  able  to  renew  our  lease  when  needed  on  acceptable  terms  or  find  alternative  facilities.  See  Note  10  "Leased  Properties"  to  the  accompanying  consolidated
financial statements for more information about our real property leases.

ITEM 3. LEGAL PROCEEDINGS

From time to time, we may become involved in various claims and legal proceedings. Regardless of outcome, litigation and other legal proceedings can have
an adverse impact on us because of defense and settlement costs, diversions of management resources and other factors. As of the date of filing this report, there is no
material pending legal proceeding to which we are a party or to which any of our property is subject, and management is not aware of any contemplated proceeding by
any governmental authority against us.

ITEM 4. MINE SAFETY DISCLOSURES

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our consolidated financial statements and the notes thereto included in Part II, Item 8 of
this  report.  This  following  discussion  includes  forward-looking  statements.  See  PART  I  "CAUTIONARY  NOTE  REGARDING  FORWARD-LOOKING
STATEMENTS,”  above.  Forward-looking  statements  are  not  guarantees  of  future  performance  and  our  actual  results  may  differ  materially  from  those
currently anticipated and from historical results depending upon a variety of factors, including, but not limited to, those discussed in Part I, Item 1A of this
report under the heading “Risk Factors,” which are incorporated herein by reference.

Business Overview

We  are  a  biopharmaceutical  company  committed  to  advancing  innovative  products  for  women’s  health.  We  are  driven  by  a  mission  to  identify,  develop  and
bring to market a diverse portfolio of differentiated therapies that prioritize women's health and well-being, expand treatment options, and improve outcomes, primarily in
the areas of contraception, vaginal health, reproductive health, menopause, sexual health and fertility. Our business strategy is to in-license or otherwise acquire the
rights to differentiated product candidates in our areas of focus, some of which have existing clinical proof-of-concept data, to take those candidates through mid to late-
stage  clinical  development  or  regulatory  approval,  and  to  establish  and  leverage  strategic  collaborations  to  achieve  commercialization.  We  and  our  wholly-owned
subsidiaries operate in one business segment.

The first FDA-approved product to emerge from our portfolio of women's health product candidates is XACIATO (clindamycin phosphate) vaginal gel 2%, or
XACIATO (pronounced zah-she-AH-toe). XACIATO was approved by the FDA in December 2021 as a single-dose prescription medication for the treatment of bacterial
vaginosis  in  females  12  years  of  age  and  older.  In  March  2022,  we  entered  into  an  agreement  with  an  affiliate  of  Organon  &  Co.,  Organon  International  GmbH,  or
Organon,  which  became  fully  effective  in  June  2022,  whereby  Organon  licensed  exclusive  worldwide  rights  to  develop,  manufacture  and  commercialize  XACIATO.
Accordingly, our

107

potential  future  revenue  from  the  commercialization  of  XACIATO  will  consist  of  royalties  based  on  net  sales  and  milestone  payments  from  Organon.  Organon
commenced U.S. marketing of XACIATO in the fourth quarter of 2023.

Our product pipeline includes diverse programs that target unmet needs in women's health in the areas of contraception, vaginal health, reproductive health,
menopause,  sexual  health  and  fertility,  and  aim  to  expand  treatment  options,  enhance  outcomes  and  improve  ease  of  use  for  women.  We  are  primarily  focused  on
progressing  the  development  of  our  existing  portfolio  of  product  candidates.  However,  we  also  explore  opportunities  to  expand  our  portfolio  by  leveraging  assets  to
which we hold rights or obtaining rights to new assets, with continued focus solely on women's health.

Our current portfolio includes five product candidates in advanced clinical development (Phase 2-ready to Phase 3):

• Ovaprene®, a hormone-free, monthly intravaginal contraceptive;

•

Sildenafil Cream, 3.6%, a proprietary cream formulation of sildenafil for topical administration to the female genitalia on demand for the treatment of
female sexual arousal disorder (FSAD);

• DARE-HRT1, an intravaginal ring designed to deliver both bio-identical estradiol and progesterone together, continuously over a 28-day period, for the

treatment of moderate-to-severe vasomotor symptoms, as part of menopausal hormone therapy;

• DARE-VVA1, a proprietary formulation of tamoxifen for intravaginal administration being developed as a hormone-free alternative to estrogen-based
therapies for the treatment of moderate-to-severe dyspareunia, or pain during sexual intercourse, a symptom of vulvar and vaginal atrophy associated
with menopause; and

• DARE-CIN, a proprietary, fixed-dose formulation of lopinavir and ritonavir in a soft gel vaginal insert for the treatment of cervical intraepithelial neoplasia

(CIN) and other human papillomavirus (HPV)-related pathologies.

Our portfolio also includes five product candidates in Phase 1 clinical development or that we believe are Phase 1-ready:

• DARE-PDM1,  a  proprietary  hydrogel  formulation  of  diclofenac,  a  nonsteroidal  anti-inflammatory  drug,  for  vaginal  administration  as  a  treatment  for

primary dysmenorrhea;

• DARE-204 and DARE-214, injectable formulations of etonogestrel designed to provide contraception over 6-month and 12-month periods, respectively;

• DARE-FRT1, an intravaginal ring designed to deliver bio-identical progesterone continuously for up to 14 days for luteal phase support as part of an in

vitro fertilization treatment plan; and

• DARE-PTB1, an intravaginal ring designed to deliver bio-identical progesterone continuously for up to 14 days for the prevention of preterm birth.

In addition, our portfolio includes five preclinical stage programs:

• DARE-LARC1,  a  contraceptive  implant  delivering  levonorgestrel  with  a  woman-centered  design  that  has  the  potential  to  be  a  long-acting,  yet

convenient and user-controlled contraceptive option;

• DARE-LBT, a novel hydrogel formulation for vaginal delivery of live biotherapeutics to support vaginal health;

• DARE-GML, an intravaginally-delivered potential multi-target antimicrobial agent formulated with glycerol monolaurate (GML), which has shown broad

antimicrobial activity, killing bacteria and viruses;

• DARE-RH1, a novel approach to non-hormonal contraception for both men and women by targeting the CatSper ion channel; and

• DARE-PTB2, a novel approach for the prevention and treatment of idiopathic preterm birth through inhibition of a stress response protein.

108

The  product  candidates  and  potential  product  candidates  in  our  portfolio  will  require  review  and  approval  from  the  FDA,  or  a  comparable  foreign  regulatory

authority, prior to being marketed or sold. See ITEM 1. "BUSINESS," in Part I of this report for additional information regarding our product and product candidates.

Our  primary  operations  have  consisted  of  research  and  development  activities  to  advance  our  portfolio  of  product  candidates  through  late-stage  clinical
development and/or regulatory approval. We expect our research and development expenses will continue to represent the majority of our operating expenses for at
least the next twelve months. Until we secure additional capital to fund our operating needs, we will focus our resources primarily on advancement of Ovaprene and
Sildenafil Cream. In addition, we expect to incur significant research and development expenses for the DARE-LARC1 program for the next several years, but we also
expect such expenses will be supported by non-dilutive funding provided under a grant agreement we entered into in June 2021.

As discussed below, we will need to raise substantial additional capital to continue to fund our operations and execute our current business strategy. We are
also subject to a number of other risks common to biopharmaceutical companies, including, but not limited to, dependence on key employees, reliance on third-party
collaborators,  service  providers  and  suppliers,  being  able  to  develop  commercially  viable  products  in  a  timely  and  cost-effective  manner,  dependence  on  intellectual
property we own or in-license and the need to protect that intellectual property and maintain those license agreements, uncertainty of market acceptance of products,
uncertainty  of  third-party  payor  coverage,  pricing  and  reimbursement  for  products,  rapid  technology  change,  intense  competition,  compliance  with  government
regulations, product liability claims, and exposure to cybersecurity threats and incidents.

The process of developing and obtaining regulatory approvals for prescription drug and drug/device products in the United States and in foreign jurisdictions is
inherently uncertain and requires the expenditure of substantial financial resources without any guarantee of success. To the extent we receive regulatory approvals to
market  and  sell  our  product  candidates,  the  commercialization  of  any  product  and  compliance  with  subsequently  applicable  laws  and  regulations  requires  the
expenditure  of  further  substantial  financial  resources  without  any  guarantee  of  commercial  success.  The  amount  of  post-approval  financial  resources  required  for
commercialization and the potential revenue we may receive from sales of any product will vary significantly depending on many factors, including whether, and the
extent  to  which,  we  establish  our  own  sales  and  marketing  capabilities  and/or  enter  into  and  maintain  commercial  collaborations  with  third  parties  with  established
commercialization infrastructure.

Recent Events

Sildenafil Cream Positive End-of-Phase 2b Meeting with FDA

As discussed in ITEM 1. "BUSINESS" in Part I of this report, in January 2024, we announced the successful completion of an end-of-Phase 2 meeting with the

FDA supporting advancement of Sildenafil Cream for the treatment of FSAD to Phase 3 clinical development.

Noncompliance with Nasdaq’s Minimum Bid Price Requirement

On January 17, 2024, the Nasdaq Staff notified us that because we had not timely regained compliance with the Minimum Bid Price Requirement, our common
stock was subject to delisting from The Nasdaq Capital Market unless we timely requested a hearing before the Nasdaq Hearings Panel, or the Panel, to appeal the
Nasdaq Staff’s delisting determination. We submitted a timely request for a hearing before the Panel, which stayed the suspension and delisting of our common stock
pending the decision of the Panel and the expiration of any extension period granted by the Panel.

On  February  27,  2024,  the  Panel  notified  us  that,  based  on  its  review  of  the  written  record,  which  included  our  commitment  to  effect  a  reverse  stock  split  if
necessary to regain compliance with the Minimum Bid Price Requirement, it determined to grant us a temporary exception until July 15, 2024 (the “Exception Period”) to
regain  compliance  with  the  Minimum  Bid  Price  Requirement.  The  Panel  granted  the  temporary  exception  subject  to  us  obtaining  board  of  directors  and  stockholder
approval for and effecting the reverse stock split on or before specified dates that would enable us to demonstrate compliance with the Minimum Bid Price Requirement
by evidencing a closing bid price of $1.00 or more per share for a minimum of ten consecutive trading sessions on or before July 15, 2024. The Panel advised us that,
during the Exception Period, we must provide Nasdaq with prompt notification of any significant events that may affect our compliance with Nasdaq listing requirements,
including any event that may call into question our ability to meet the terms of the temporary exception. The Panel also advised us that should we fail to meet any of the
terms of the temporary exception, our common stock will immediately be delisted.

109

Receipt of Grant to Support Biotherapeutic Product Development

On January 17, 2024, we entered into a grant agreement with the Bill & Melinda Gates Foundation, or the Foundation, pursuant to which we received $750,000
in grant funding to gather and analyze data on the global bacterial biologic supply chain to help the Foundation identify potential contract manufacturing organization
partners for manufacturing clinical and commercial supplies of bacteria-based biotherapeutic products.

Royalty Interest Financing Agreement

On December 21, 2023, we entered into a royalty interest financing agreement with United in Endeavour, LLC, or United, pursuant to which we sold to United
an  interest  in  royalty  and  milestone  payments  we  receive  from  Organon  based  on  net  sales  of  XACIATO  for  a  purchase  price  of  up  to  $12  million.  We  received  a
payment of $5.0 million from United on the date of the agreement, and until December 31, 2026, we may, in our sole discretion, elect to receive up to three additional
payments from United of up to an aggregate of $7 million. Pursuant to the terms of the agreement, on December 21, 2023, we issued to United a warrant to purchase
up to 5.0 million shares of our common stock. In addition, for every additional $1.0 million payment we elect to receive from United under the agreement, we agreed to
issue warrants to purchase up to 1.0 million shares of our common stock, for an aggregate of warrants to purchase up to 7.0 million shares of our common stock. The
initial warrant has, and each additional warrant, if any, will have, an exercise price of $0.3467 per share, subject to customary adjustments, and is or will be exercisable,
in full or in part, at any time from the date of issuance on or prior to the fifth anniversary of the date of issuance of the particular warrant. For more information, see ITEM
1.  “BUSINESS—  Royalty  Interest  Financing  Agreement”  in  Part  I  of  this  report  and  Note  11  “Sale  of  Future  Royalties”  to  the  accompanying  consolidated  financial
statements.

Positive Topline Data from Phase 1 Clinical Study of DARE-PDM1

As discussed in ITEM 1. "BUSINESS" in Part I of this report, on December 20, 2023, we announced positive topline data from our Phase 1 clinical study of

DARE-PDM1.

Financial Overview

Revenue

To date we have generated approximately $12.8 million in revenue, all from payments received under our license agreement with Organon to commercialize
XACIATO. In the future, we expect to continue to generate revenue from royalties based on the net sales of XACIATO and we may generate revenue from commercial
milestones based on the net sales of XACIATO, from product sales of other approved products, if any, and from license fees, milestone payments, and research and
development payments in connection with strategic collaborations. Our ability to generate such revenue, with respect to XACIATO, will depend on the extent to which its
commercialization is successful, and with respect to our product candidates, will depend on their successful clinical development, the receipt of regulatory approvals to
market  such  product  candidates  and  the  eventual  successful  commercialization  of  products.  If  XACIATO  is  not  commercially  successful  or  we  fail  to  complete  the
development of our product candidates in a timely manner, or to receive regulatory approval for such product candidates, our ability to generate future revenue and our
results of operations would be materially adversely affected.

Research and Development Expenses

The majority of our operating expenses during a fiscal year are research and development expenses, a significant portion of which, excluding those funded by
non-dilutive grants, are associated with the clinical development for our product candidates that have reached the human clinical study development phase. Research
and  development  expenses  include  research  and  development  costs  for  our  product  candidates  and  transaction  costs  related  to  our  acquisitions.  We  recognize  all
research and development expenses as they are incurred. Research and development expenses consist primarily of:

•

•

•

•

expenses incurred under agreements with clinical trial sites and consultants that conduct research and development and regulatory affairs activities on our
behalf;

laboratory and vendor expenses related to the execution of nonclinical studies and clinical trials;

contract manufacturing expenses, primarily for the production of clinical supplies;

transaction costs related to acquisitions of companies, technologies and related intellectual property, and other assets;

110

•

•

milestone payments due to third parties under acquisition and in-licensing arrangements we incur, or the incurrence of which we deem probable; and

internal costs associated with activities performed by our research and development organization and generally benefit multiple programs.

Investment in the development of and seeking regulatory approval for our clinical-stage and Phase 1-ready product candidates and the development of any
other potential product candidates we may advance into and through clinical trials in the pursuit of regulatory approvals, will increase our research and development
expenses.  Activities  associated  with  the  foregoing  will  require  a  significant  increase  in  investment  in  regulatory  support,  clinical  supplies,  inventory  build-up  related
costs, and the payment of success-based milestones to licensors. In addition, we continue to evaluate opportunities to acquire or in-license other product candidates
and technologies, which may result in higher research and development expenses due to, among other factors, license fee and/or milestone payments.

Until the first commercial sale of XACIATO, we recognized contract manufacturing expenses associated with producing commercial supplies of XACIATO and
costs of regulatory affairs activities related to XACIATO as research and development expenses. Following the first commercial sale of XACIATO, and during the interim
period  when  we  were  the  NDA  holder  of  XACIATO  and  provided  commercial  supplies  of  XACIATO  to  Organon,  those  expenses  are  recognized  as  general  and
administrative expenses.

We recognize the Australian Research and Development Tax Incentive Program, or the Tax Incentive, as a reduction of research and development expenses.
The  amounts  are  determined  based  on  our  eligible  research  and  development  expenditures  and  are  non-refundable,  provided  that  in  order  to  qualify  for  the  Tax
Incentive the filing entity must have revenue of less than AUD $20.0 million during the tax year for which a reimbursement claim is made and cannot be controlled by an
income tax exempt entity. The Tax Incentive is recognized when there is reasonable assurance that the Tax Incentive will be received, the relevant expenditure has
been incurred, and the amount can be reliably measured or reliably estimated.

We receive funding through grants that support activities related to the development of certain of our product candidates. As we incur eligible expenses under
those  grants,  we  recognize  grant  funding  in  the  statements  of  operations  as  a  reduction  to  research  and  development  expenses  (contra-research  and  development
expense).  For  more  information,  see  Note  2,  Basis  of  Presentation  and  Summary  of  Significant  Accounting  Policies  –  Grant  Funding,  to  our  consolidated  financial
statements  contained  herein.  For  the  years  ended  December  31,  2023  and  2022,  we  recognized  contra-research  and  development  expense  of  approximately  $9.3
million and $5.6 million, respectively.

Conducting  clinical  trials  necessary  to  obtain  regulatory  approval  is  costly  and  time  consuming.  We  may  not  obtain  regulatory  approval  for  any  product
candidate  on  a  timely  or  cost-effective  basis,  or  at  all.  The  probability  of  success  of  our  product  candidates  may  be  affected  by  numerous  factors,  including  clinical
results and data, competition, intellectual property rights, manufacturing capability and commercial viability. As a result, we cannot accurately determine the duration
and completion costs of development projects or when and to what extent we will generate revenue from the commercialization of any of our product candidates.

License Fee Expenses

License fee expenses consist of up-front license fees and annual license fees due under our in-licensing arrangements.

General and Administrative Expenses

General  and  administrative  expenses  consist  of  personnel  costs,  facility  expenses,  expenses  for  outside  professional  services,  including  legal,  audit  and
accounting  services,  commercial-readiness  expenses,  and  royalty  and  milestone  expenses.  Personnel  costs  consist  of  salaries,  benefits  and  stock-based
compensation.  Facility  expenses  consist  of  rent  and  other  related  costs.  Commercial-readiness  expenses  consist  of  consultant  and  advisor  costs.  Royalty  and
milestone expenses consist of payments we owe under our in-license agreements.

Recently Issued Accounting Standards

From time to time, the Financial Accounting Standards board, or FASB, or other standard setting bodies issue new accounting pronouncements. Updates to the
FASB Accounting Standards Codification, or ASC, are communicated through issuance of an Accounting Standards Update. We have implemented all new accounting
pronouncements that are in effect and that may impact our financial statements. We have evaluated recently issued

111

accounting pronouncements and determined that there is no material impact on our financial position or results of operations.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements that we prepared in
accordance  with  accounting  principles  generally  accepted  in  the  United  States.  Preparing  these  financial  statements  requires  management  to  make  estimates  and
judgments  that  affect  the  reported  amounts  of  assets,  liabilities  and  expenses,  and  related  disclosures.  On  an  ongoing  basis,  we  evaluate  these  estimates  and
judgments. We base our estimates on historical experience and on various assumptions we believe to be reasonable under the circumstances. These estimates and
assumptions form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from
other sources. Actual results may differ materially from these estimates. Historically, revisions to our estimates have not resulted in a material change to our financial
statements. While our significant account policies are described in more detail in Note 2 to our consolidated financial statements included herein, we believe that the
following accounting policies are most important to the portrayal of our financial condition and results of operations and require management's most difficult, subjective
and complex judgments.

Revenue Recognition

Under  ASC  Topic  606,  or  ASC  606,  we  recognize  revenue  when  promised  goods  or  services  are  transferred  to  customers  in  an  amount  that  reflects  the
consideration to which we expect to be entitled in exchange for those goods or services. To determine revenue recognition for contracts with customers, we perform five
steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction
price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy our performance obligations. At contract inception, we assess
the goods or services agreed upon within each contract, assess whether each good or service is distinct, and determines those that are performance obligations. We
then recognize as revenue the amount of the transaction price allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

In  a  contract  with  multiple  performance  obligations,  we  develop  estimates  and  assumptions  that  require  judgment  to  determine  the  underlying  stand-alone
selling price for each performance obligation, which determines how the transaction price is allocated among the performance obligations. The estimation of the stand-
alone selling price(s) may include estimates regarding forecasted revenues or costs, development timelines, discount rates, and probabilities of technical and regulatory
success. We evaluate each performance obligation to determine if it can be satisfied at a point in time or over time. Any change made to estimated progress towards
completion  of  a  performance  obligation  and,  therefore,  revenue  recognized  will  be  recorded  as  a  change  in  estimate.  In  addition,  variable  consideration  must  be
evaluated to determine if it is constrained and, therefore, excluded from the transaction price.

Collaboration Revenues. We enter into collaboration and licensing agreements under which we out-license certain rights to our products or product candidates
to third parties. The terms of these arrangements typically include payment of one or more of the following to us: non-refundable, up-front license fees; development,
regulatory and/or commercial milestone payments; and royalties on net sales of licensed products. To date, we have not recognized any collaboration revenues.

License Fee Revenue. If the license to our intellectual property is determined to be distinct from the other performance obligations identified in a contract, we
recognize  revenues  from  non-refundable,  upfront  fees  allocated  to  the  license  when  the  license  is  transferred  to  the  customer  and  the  customer  is  able  to  use  and
benefit  from  the  license.  For  licenses  bundled  with  other  promises,  we  utilize  judgment  to  assess  the  nature  of  the  combined  performance  obligation  to  determine
whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of
recognizing  revenue  from  non-refundable,  upfront  fees.  We  evaluate  the  measure  of  progress  each  reporting  period  and,  if  necessary,  adjust  the  measure  of
performance  and  related  revenue  recognition.  To  date,  we  have  recognized  $11.0  million  in  license  fee  revenue,  all  from  payments  received  under  our  license
agreement with Organon to commercialize XACIATO.

Milestones. At the inception of each arrangement in which we are a licensor and that includes developmental, regulatory or commercial milestones, we evaluate
whether achieving the milestones is considered probable and estimate the amount to be included in the transaction price using the most likely amount method. If it is
probable  that  a  significant  revenue  reversal  would  not  occur,  the  associated  milestone  value  is  included  in  the  transaction  price.  Milestone  payments  not  within  our
control,  such  as  where  achievement  of  the  specified  milestone  depends  on  activities  of  a  third  party  or  regulatory  approval,  are  not  considered  probable  of  being
achieved until the specified milestone occurs. To date, we have recognized $1.8 million of milestone revenue, which represents the $1.8 million

112

milestone payment we received under our license agreement with Organon in connection with the first commercial sale of XACIATO.

Royalties. For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and for which the license is deemed
to be the predominant item to which the royalties relate, we recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to
which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, we have recognized approximately $7,900 of royalty revenue.

Product Supply. Arrangements that include a promise for future supply of product for commercial supply at the licensee’s discretion are generally considered as
options. We assess if these options provide a material right to the licensee and if so, they are accounted for as separate performance obligations. We evaluate whether
we are the principal or agent in the arrangement based on the degree we control the specified product at any time before transfer to the customer. If we are in the
capacity of a principal, revenues are recognized on a gross basis. If we are in the capacity of an agent, revenues are recognized on a net basis. To date, we have
recognized  approximately  $205,000  in  revenue  (and  $201,000  in  other  expense  attributed  to  the  cost  of  revenue)  associated  with  our  XACIATO  product  supply
arrangement, which is recorded in other income in our consolidated statements of operations and comprehensive loss. In connection with the transfer of the NDA for
XACIATO to Organon in December 2023, that arrangement was terminated and we will not recognize product supply revenue associated with that arrangement in the
future.

Stock-Based Compensation

The  compensation  cost  for  all  stock-based  awards  is  measured  at  the  grant  date,  based  on  the  fair  value  of  the  award  (determined  using  a  Black-Scholes
option pricing model), and is recognized as an expense over the requisite service period (generally the vesting period of the award). Determining the fair value of stock-
based awards at the grant date requires significant estimates and judgments, including estimating the market price volatility of our common stock, future stock option
exercise  behavior  and  requisite  service  periods.  Due  to  our  limited  history  of  stock  option  exercises  we  applied  the  simplified  method  prescribed  by  SEC  Staff
Accounting Bulletin 110, Share-Based Payment: Certain Assumptions Used in Valuation Methods - Expected Term, to estimate expected life.

Stock  options  or  stock  awards  with  performance  conditions  issued  to  non-employees  who  are  not  directors  are  measured  on  the  grant  date  and  recognized

when the performance is complete. Refer to Note 9 to our consolidated financial statements included in this report for more information.

Grant Funding

We receive certain research and development funding under grants issued by the U.S. government and a not-for-profit foundation. In accordance with a policy
we adopted in 2018, we recognize grant funding in the statements of operations as a reduction to research and development expense as the related costs are incurred
to meet those obligations over the grant period. Grant funding payments received in advance of research and development expenses incurred are recorded as deferred
grant funding liability in our consolidated balance sheets. For the years ended December 31, 2023 and December 31, 2022, there were no material adjustments to our
prior period estimates of grant funded research and development expenses. Refer to Note 13 to our consolidated financial statements included in this report for more
information.

Clinical Trial Expense Accruals

We estimate expenses resulting from our obligations under contracts with vendors, CROs and consultants and under clinical site agreements in connection with
conducting clinical trials. The financial terms of these contracts vary and may result in payment flows that do not match the periods over which materials or services are
provided.

We  record  clinical  trial  expenses  in  the  period  in  which  services  are  performed  and  efforts  are  expended.  We  accrue  for  these  expenses  according  to  the
progress of the trial as measured by patient progression and the timing of various aspects of the trial. We estimate accruals through financial models taking into account
discussion with applicable personnel and outside service providers as to the progress of trials. During the course of a clinical trial, we may adjust our clinical accruals if
actual results differ from our estimates. We estimate accrued expenses as of each balance sheet date based on the facts and circumstances known at that time. Our
clinical trial accruals are dependent upon accurate reporting by CROs and other third-party vendors. Although we do not expect our estimates to differ materially from
amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and
may result in reporting amounts that are too high or

113

too low for any particular period. For the years ended December 31, 2023 and December 31, 2022 there were no material adjustments to our prior period estimates of
accrued expenses for clinical trials.

Revenues

Revenues  for  the  years  ended  December  31,  2023  and  2022  related  to  our  license  agreement  with  Organon  to  commercialize  XACIATO.  For  2023,  we
recognized $1.0 million in license fee revenue upon execution of the amendment to the license agreement in July 2023, $1.8 million in milestone revenue in connection
with  the  first  commercial  sale  of  XACIATO,  and  approximately  $7,900  in  royalties  from  net  sales  of  XACIATO  in  the  fourth  quarter.  For  2022,  we  recognized  $10.0
million in license fee revenue related to the transfer of the license and related know-how to Organon upon effectiveness of the license agreement in June 2022.

General and administrative expenses

The increase of approximately $0.9 million in general and administrative expenses from 2022 to 2023 was primarily attributable to (i) a $0.5 million commercial
milestone  due  under  our  license  agreement  for  XACIATO,  (ii)  $0.4  million  of  commercial-readiness  expenses  related  to  XACIATO,  (iii)  a  one-time  fraud  loss  of
approximately $0.2 million, net of proceeds we received under an insurance policy, related to criminal fraud commonly referred to as "business email compromise fraud"
to which we were subject, and (iv) an increase in stock-based compensation expense of approximately $0.2 million. The foregoing were partially offset by decreases in
personnel  costs  of  approximately  $0.6  million  due  to  decreased  bonus  expense,  and  general  corporate  overhead,  including  rent  and  facilities  expenses,  of
approximately $26,000.

Research and development expenses

The  decrease  of  approximately  $8.5  million  in  research  and  development  expenses  from  2022  to  2023  was  primarily  attributable  to  decreases  in  (i)  costs
related to development activities for Sildenafil Cream of approximately $6.4 million, (ii) costs related to manufacturing and regulatory affairs activities for Ovaprene of
approximately $2.0 million, (iii) costs related to development activities for XACIATO of approximately $0.2 million, (iv) rent and facilities expenses of approximately $0.1
million, and (v) costs related to development activities for our preclinical programs and other development expenses of approximately $69,000. Such decreases were
partially offset by increases in (a) costs related to development activities for our Phase 1 and Phase 1-ready programs of approximately $0.2 million, and (b) stock-
based compensation expense of approximately $0.1 million.

114

License fee expenses

For each of the years ended December 31, 2023 and December 31, 2022 we accrued or paid $100,000 of the annual license maintenance fee payable under
our  license  agreement  related  to  DARE-HRT1.  For  further  discussion  of  this  annual  license  maintenance  fee,  see  Note  3  "Strategic  Agreements—  Strategic
Agreements for Pipeline Development" to the accompanying consolidated financial statements.

Other income

The increase of $0.3 million in other income from 2022 to 2023 was primarily due to an increase in interest earned on cash balances in 2023 due to higher

interest rates.

Liquidity and Capital Resources

Plan of Operations and Future Funding Requirements

At December 31, 2023, our accumulated deficit was approximately $171.2 million, our cash and cash equivalents were approximately $10.5 million, and our
working capital deficit was approximately $2.9 million. We incurred a loss of approximately $30.2 million and had negative cash flow from operations of approximately
$38.9 million for the year ended December 31, 2023.

Our cash and cash equivalents at December 31, 2023 represented funds received under grant agreements related to DARE-LARC1 and DARE-LBT and such
funds  may  be  applied  solely  toward  direct  costs  for  the  development  of  DARE-LARC1  and  DARE-LBT,  other  than  approximately  10%  of  such  funds,  which  may  be
applied  toward  general  overhead  and  administration  expenses  that  support  our  entire  operations.  For  additional  information  about  these  grant  agreements,  see  "—
Deferred  Grant  Funding"  and  "—Grant  Agreements,"  below.  We  expect  to  incur  significant  losses  from  operations  and  negative  cash  flows  from  operations  for  the
foreseeable future as we continue to develop and seek to bring to market our product candidates.

The majority of our operating expenses during a fiscal year are research and development expenses, a significant portion of which, excluding those funded by
non-dilutive grants, are associated with the clinical development for our product candidates that have reached the human clinical study development phase. In large
part,  we  can  control  the  pace  of  advancement  of  our  development  programs  and  therefore,  we  can  control  the  timing  of  when  we  incur  most  of  our  research  and
development  expenses.  We  expect  our  primary  uses  of  capital  to  be  staff-related  expenses,  the  cost  of  clinical  trials  and  regulatory  activities  related  to  our  product
candidates, costs associated with contract manufacturing services and third-party clinical research and development services, payments to third-party licensors upon
the occurrence of commercial milestones for XACIATO and development milestones for our product candidates pursuant to terms of the agreements under which we
acquired or in-licensed rights to those programs, legal expenses, other regulatory expenses and general overhead costs. Our future funding requirements could also
include significant costs related to commercialization of our product candidates, if approved, depending on the type, nature and terms of commercial collaborations we
establish, and in particular, if we determine to engage in commercialization activities directly as opposed to through a third-party collaborator. We anticipate our general
and administrative expenses for 2024 will be consistent with our general and administrative expenses for 2023.

Under the royalty interest financing agreement we entered into in December 2023, we may, in our sole discretion, elect to receive up to an additional aggregate
amount  of  $7.0  million.  Under  our  license  agreement  relating  to  XACIATO,  we  may  receive  royalty  payments  based  on  net  sales  of  XACIATO,  however,  we  do  not
expect such royalty payments for 2024 to materially impact our cash resources or requirements.

We  closely  monitor  our  limited  cash  resources  and  we  have  implemented  cost-savings  measures,  primarily  by  controlling  our  spend  on  research  and
development activities related to clinical-stage programs other than Ovaprene and Sildenafil Cream. Our research and development expenses for 2024, until we secure
additional  capital  to  fund  our  operating  needs,  will  continue  to  be  primarily  associated  with  manufacturing  activities  in  connection  with  our  ongoing  pivotal  Phase  3
clinical study of Ovaprene and activities, including regulatory affairs activities, related to advancing Sildenafil Cream toward a Phase 3 clinical study. However, we plan
to continue to advance preclinical development of DARE-LARC1, the costs of which are being supported by grant funding.

We will need additional capital to fund our operating needs into the third quarter of 2024 and to meet our current obligations as they become due. We are in
ongoing  discussions  with  multiple  potential  third-party  sources  of  additional  capital,  including  non-dilutive  sources  of  capital.  Many  aspects  of  our  ability  to  obtain
additional capital are not entirely within our control and there can be no assurance that we will receive additional capital when needed, on

115

favorable terms, or at all. If we cannot raise capital when needed, on favorable terms or at all, we will not be able to continue development of our product candidates,
will  need  to  reevaluate  our  planned  operations  and  may  need  to  delay,  scale  back  or  eliminate  some  or  all  of  our  development  programs,  reduce  expenses,  file  for
bankruptcy, reorganize, merge with another entity, or cease operations. If we become unable to continue as a going concern, we may have to liquidate our assets, and
might realize significantly less than the values at which they are carried on our financial statements, and stockholders may lose all or part of their investment in our
common stock. See the risk factor in Item 1A of Part I of this report titled, We will need to raise substantial additional capital to continue our operations and execute our
business strategy, and we may not be able to raise adequate capital on a timely basis, on favorable terms, or at all.

Historically, the cash used to fund our operations has come from a variety of sources and predominantly from sales of shares of our common stock. We have
also received a significant amount of cash through non-dilutive grants and strategic collaborations. We will continue to evaluate and may pursue a variety of capital
raising  options  on  an  on-going  basis,  including  sales  of  equity  (including  sales  of  our  common  stock  in  ATM  offerings),  debt  financings,  government  or  other  grant
funding,  collaborations,  structured  financings,  and  strategic  alliances  or  other  similar  types  of  arrangements,  to  cover  our  operating  expenses,  and  the  cost  of  any
license or other acquisition of new product candidates or technologies. There can be no assurance that capital will be available when needed or that, if available, it will
be obtained on terms favorable to us and our stockholders. Our ability to raise capital through sales of our common stock will depend on a variety of factors including,
among others, market conditions, the trading price and volume of our common stock, our clinical and commercial developments, and investor sentiment. In addition,
macroeconomic factors and volatility in the financial market, which may be exacerbated in the short term by concerns over inflation, interest rates, economic recession,
adverse developments affecting financial institutions or the financial services industry, impacts of the wars in Ukraine and the Middle East, strained relations between
the U.S. and several other countries, and social and political discord and unrest in the U.S., among other things, may make equity or debt financings more difficult, more
costly or more dilutive to our stockholders, and may increase competition for, or limit the availability of, funding from other potential third-party sources of capital, such
as strategic collaborators and sources of grant funding.

In addition, equity or debt financings may have a dilutive effect on the holdings of our existing stockholders, and debt financings may subject us to restrictive
covenants,  operational  restrictions  and  security  interests  in  our  assets.  If  we  raise  capital  through  collaborations,  structured  financings,  strategic  alliances  or  other
similar types of arrangements, we may be required to relinquish some or all of our rights to potential revenue or to intellectual property rights for our product candidates
on terms that are not favorable to us.

We  prepared  the  accompanying  consolidated  financial  statements  on  a  going  concern  basis,  which  assumes  that  we  will  realize  our  assets  and  satisfy  our
liabilities  in  the  normal  course  of  business.  As  discussed  above,  there  is  substantial  doubt  about  our  ability  to  continue  as  a  going  concern.  The  accompanying
consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and reclassification of assets or the amounts
and classifications of liabilities that may result from the outcome of the uncertainty of our ability to remain a going concern.

Deferred Grant Funding

We have received substantial funding under grant agreements related to DARE-LARC1 and DARE-LBT. Under these agreements, and under the agreement we
received  from  the  Foundation  in  January  2024  to  fund  activities  related  to  bacteria-based  live  biotherapeutic  product  development,  we  generally  receive  grant  funds
before we incur the eligible expenses. Funds received that have not been spent are recorded both as cash and cash equivalents and as a deferred grant funding liability
in  our  consolidated  balance  sheets.  Our  deferred  grant  funding  liability  also  includes  grant  funds  spent  but  not  yet  expensed  in  accordance  with  GAAP.  As  of
December 31, 2023, our deferred grant funding liability was approximately $13.7 million, which primarily consisted of unspent funds for the DARE-LARC1 program. The
balance  of  our  deferred  grant  funding  liability  at  December  31,  2023  primarily  consisted  of  funds  for  the  DARE-LARC1  program  that  have  been  spent  but  not  yet
expensed  in  accordance  with  GAAP.  For  more  information  about  these  grant  agreements,  see  "—Grant  Agreements"  below,  and  Note  2,  Basis  of  Presentation  and
Summary of Significant Accounting Policies—Grant Funding, and Note 13, Grant Awards-Other Non-Dilutive Grant Funding to the accompanying consolidated financial
statements.

Net cash provided by financing activities

Cash provided by financing activities during the year ended December 31, 2023 consisted of proceeds from (i) the sale of our common stock and warrants in

License and Royalty Agreements

We agreed to make royalty and milestone payments under the license and development agreements related to XACIATO, Ovaprene, and Sildenafil Cream, and
under  other  agreements  related  to  our  other  clinical  and  preclinical  candidates.  During  2024,  based  on  our  current  expectations  regarding  the  development  of  our
product  candidates  and  sales  of  XACIATO,  we  expect  to  pay  approximately  $2.8  million  in  royalty  and  milestone  payments  under  the  license  and  development
agreements.  For  further  discussion  of  these  potential  payments,  see  Note  3  "Strategic  Agreements—Strategic  Agreements  for  Pipeline  Development"  to  the
accompanying consolidated financial statements.

Grant Agreements

We have received substantial funding under grant agreements related to DARE-LARC1 and DARE-LBT. In September 2023, following an assessment of our

activities and the milestones we achieved to date, we received $4.5

117

million as the latest installment under the grant agreement to advance the preclinical development of DARE-LARC1. Grant funds under these agreements, and under
the  agreement  we  received  from  the  Foundation  in  January  2024  to  fund  activities  related  to  bacteria-based  live  biotherapeutic  product  development,  generally  are
received before we incur the eligible expenses. Unspent grant funds are recorded as deferred grant funding liability in our consolidated balance sheets and our deferred
grant funding liability as of December 31, 2023 primarily consisted of unspent grant funds for the DARE-LARC1 program. For more information, see Note 2, Basis of
Presentation  and  Summary  of  Significant  Accounting  Policies—Grant  Funding,  and  Note  13,  Grant  Awards-Other  Non-Dilutive  Grant  Funding  to  the  accompanying
consolidated financial statements.

Other Contractual Obligations

We enter into contracts in the normal course of business with various third parties for research studies, clinical trials, testing and other services. These contracts

generally provide for termination upon notice, and we do not believe that our non-cancelable obligations under these agreements are material.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under applicable SEC rules.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Under SEC rules and regulations, as a smaller reporting company we are not required to provide the information required by this item.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Our consolidated financial statements required to be included in this Item 8 are set forth in a separate section of this report commencing on page F-1.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) designed to provide reasonable assurance that information
required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms,
and that such information is accumulated and communicated to our management, including our principal executive and financial officer, as appropriate, to allow timely
decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures,
no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of
assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Based on an evaluation, performed under the supervision and with the participation of our management, including our principal executive and financial officer, of
the  effectiveness  of  our  disclosure  controls  and  procedures,  our  principal  executive  and  financial  officer  concluded  that  our  disclosure  controls  and  procedures  (as
defined in Rule 13a-15(e) of the Exchange Act) were effective as of December 31, 2023 at the reasonable assurance level.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rule 13a-15(f) of
the  Exchange  Act).  Our  internal  control  over  financial  reporting  is  designed  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles.  Because  of  its  inherent  limitations,  internal  controls  over  financial
reporting may not prevent or detect misstatements. In addition, projections of any

118

evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in  conditions,  or  that  the  degree  of
compliance with the policies or procedures may deteriorate.

Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in Internal Control-
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on our assessment, management
has  concluded  that  our  internal  control  over  financial  reporting  was  effective  as  of  December  31,  2023  to  provide  reasonable  assurance  regarding  the  reliability  of
financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles in the United States.

Under SEC rules, because we are a non-accelerated filer, we are not required to provide an auditor attestation report on internal control over financial reporting,

nor did we engage our independent registered public accounting firm to perform an audit of our internal control over financial reporting.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of
the Exchange Act that occurred during the fourth quarter ended December 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal
control over financial reporting.

ITEM 9B. OTHER INFORMATION

(a) None.

(b)  During  the  period  from  October  1,  2023  to  December  31,  2023,  none  of  our  directors  or  officers  (as  defined  in  Rule  16a-1(f)  under  the  Exchange  Act)
adopted or terminated any Rule 10b5-1 trading arrangement (as defined in Item 408(a)(1)(i) of Regulation S-K) or any non-Rule 10b5-1 trading arrangement (as defined
in Item 408(c) of Regulation S-K).

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders
Daré Bioscience, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of Daré Bioscience, Inc. and Subsidiaries (the “Company”) as of December 31, 2023, and the
related consolidated statements of operations and comprehensive loss, stockholders’ equity (deficit), and cash flows for the year then ended December 31, 2023, and
the  related  notes  (collectively  referred  to  as  the  “consolidated  financial  statements”).  In  our  opinion,  the  consolidated  financial  statements  referred  to  above  present
fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2023, and the consolidated results of its operations and its cash
flows for the year then ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

The Company's Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2
to  the  consolidated  financial  statements,  the  Company  has  recurring  losses  from  operations,  negative  cash  flow  from  operations  and  is  dependent  on  additional
financing to fund operations. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to
these matters are also described in Note 2 to the consolidated financial statements. The consolidated financial statements do not include any adjustments to reflect the
possible  future  effects  on  the  recoverability  and  classification  of  assets  or  the  amounts  and  classification  of  liabilities  that  may  result  from  the  outcome  of  this
uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States)
(“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations
of the Securities and Exchange Commission and the PCAOB.

We  conducted  our  audit  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable
assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have,
nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal
control  over  financial  reporting,  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting.
Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud,
and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the
consolidated  financial  statements.  Our  audit  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matter

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to
the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or
complex judgments. We determined that there are no critical audit matters.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders
of Daré Bioscience, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Daré Bioscience, Inc. and Subsidiaries (“Company”) as of December 31, 2022, and the
related consolidated statements of operations and comprehensive loss, stockholders’ equity and cash flows for the year ended December 31, 2022, and the related
notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the
Company as of December 31, 2022, and the results of its operations and its cash flows for the year ended December 31, 2022, in conformity with accounting principles
generally accepted in the United States of America.

Daré Bioscience, Inc. and Subsidiaries

Notes to Consolidated Financial Statements

1.    ORGANIZATION AND DESCRIPTION OF BUSINESS

Organization and business

Daré Bioscience, Inc. is a biopharmaceutical company committed to advancing innovative products for women’s health. Daré Bioscience, Inc. and its wholly-
owned subsidiaries operate one segment. In this report, the “Company” refers collectively to Daré Bioscience, Inc. and its wholly-owned subsidiaries, unless otherwise
stated or the context otherwise requires.

The  Company  began  assembling  its  diverse  portfolio  in  2017  through  acquisitions,  exclusive  in-licenses  and  other  collaborations.  The  Company's  programs
target  unmet  needs  in  women's  health  in  the  areas  of  contraception,  vaginal  health,  reproductive  health,  menopause,  sexual  health,  and  fertility,  and  aim  to  expand
treatment options, enhance outcomes and improve ease of use for women.

The Company’s primary operations have consisted of, and are expected to continue to consist primarily of, research and development activities to advance its

product candidates through clinical development and regulatory approval.

The Company's portfolio includes drug and drug/device product candidates and potential product candidates in various stages of development.

The  first  U.S.  Food  and  Drug  Administration  (FDA)-approved  product  to  emerge  from  the  Company's  portfolio  of  women's  health  product  candidates  is
XACIATO™ (clindamycin phosphate) vaginal gel 2%, or XACIATO. In March 2022, the Company entered into an exclusive global license agreement with an affiliate of
Organon  &  Co.,  Organon  International  GmbH,  or  Organon,  to  commercialize  XACIATO,  which  became  fully  effective  in  June  2022.  Under  the  license  agreement,
Organon (and/or its affiliates, agents or sublicensees) is solely responsible for the marketing, distribution and sale of XACIATO in the United States (and outside the
U.S. if approved in non-U.S. jurisdictions in the future).

2.    BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States, or U.S. GAAP, as

defined by the Financial Accounting Standards Board, or FASB.

Cash, Cash Equivalents and Restricted Cash

The Company considers cash and all highly liquid investments with an original maturity of three months or less to be cash and cash equivalents. The Company
has an aggregate of approximately $0.3 million in restricted cash as of December 31, 2023, related to (i) letters of credit established under real property leases for the
Company's wholly-owned subsidiary, Dare MB Inc., that serve as security for potential future default of lease payments, and (ii) collateralized cash for the Company's
credit  cards.  The  restricted  cash  is  unavailable  for  withdrawal  or  for  general  obligations  and  is  included  in  other  non-current  assets  on  the  Company's  consolidated
balance sheet.

Going Concern

The Company prepared its consolidated financial statements on a going concern basis, which assumes that the Company will realize its assets and satisfy its
liabilities in the normal course of business. The Company has a history of losses from operations, expects negative cash flows from its operations to continue for the
foreseeable  future,  and  expects  that  its  net  losses  will  continue  for  at  least  the  next  several  years  as  it  develops  and  seeks  to  bring  to  market  its  existing  product
candidates  and  seeks  to  potentially  acquire,  license  and  develop  additional  product  candidates.  These  circumstances  raise  substantial  doubt  about  the  Company's
ability to continue as a going concern. The accompanying financial statements do not include any adjustments to reflect the possible future effects on the recoverability
and reclassification of assets or the amounts and classifications of liabilities that may result from the outcome of the uncertainty of the Company's ability to continue as
a going concern.

F-9

At December 31, 2023, the Company had an accumulated deficit of approximately $171.2 million, cash and cash equivalents of approximately $10.5 million,
deferred grant funding liabilities under the Company's grant agreements related to DARE-LARC1 and DARE-LBT of approximately $13.7 million, and a working capital
deficit of approximately $2.9 million. The Company's cash and cash equivalents at December 31, 2023 represented grant funds received under such grant agreements
that  may  be  applied  solely  toward  direct  costs  for  the  development  of  DARE-LARC1  and  DARE-LBT,  other  than  approximately  10%  of  such  funds,  which  may  be
applied  toward  general  overhead  and  administration  expenses  that  support  the  entire  operations  of  the  Company.  For  the  year  ended  December  31,  2023,  the
Company incurred a net loss of $30.2 million and had negative cash flow from operations of approximately $38.9 million.

Based on the Company's current operating plan estimates, the Company does not have sufficient cash to satisfy its working capital needs and other liquidity
requirements  over  at  least  the  next  12  months  from  the  date  of  issuance  of  the  accompanying  financial  statements.  The  Company  will  need  to  raise  substantial
additional capital to continue to fund its operations and to successfully execute its current strategy.

There  can  be  no  assurance  that  capital  will  be  available  when  needed  or  that,  if  available,  it  will  be  obtained  on  terms  favorable  to  the  Company  and  its
stockholders.  If  the  Company  cannot  raise  capital  when  needed,  on  favorable  terms  or  at  all,  the  Company  will  not  be  able  to  continue  development  of  its  product
candidates, will need to reevaluate its planned operations and may need to delay, scale back or eliminate some or all of its development programs, reduce expenses,
file for bankruptcy, reorganize, merge with another entity, or cease operations. If the Company becomes unable to continue as a going concern, the Company may have
to liquidate its assets, and might realize significantly less than the values at which they are carried on its consolidated financial statements, and stockholders may lose
all or part of their investment in the Company's common stock. The Company's consolidated financial statements do not include any adjustments that might result from
the outcome of these uncertainties.

Principles of Consolidation

The consolidated financial statements of the Company are stated in U.S. dollars. These consolidated financial statements include the accounts of the Company
and  its  wholly-owned  subsidiaries.  One  wholly-owned  subsidiary,  Daré  Bioscience  Australia  Pty  LTD,  operates  primarily  in  Australia.  The  financial  statements  of  the
Company’s wholly-owned subsidiaries are recorded in their functional currency and translated into the reporting currency. The cumulative effect of changes in exchange
rates between the foreign entity’s functional currency and the reporting currency is reported in Accumulated Other Comprehensive Loss. All intercompany transactions
and accounts have been eliminated in consolidation.

Reclassification of Prior Year Presentation

Certain  prior  year  amounts  have  been  reclassified  for  consistency  with  the  current  year  presentation.  These  reclassifications  had  no  effect  on  the  reported

results of operations.

Grant Funding

The Company receives certain research and development funding through grants issued by a division of the National Institutes of Health and the Bill & Melinda
Gates Foundation, or the Foundation. Under the Foundation grant, which the Company considers to be a research and development contract under FASB Accounting
Standards Codification, or ASC, Topic 730 Research and Development, the Company granted the Foundation a Humanitarian License which gives the Foundation the
right to make the funded developments accessible at an affordable price to people within developing countries. Grants received by the Company that do not require the
transfer  of  goods  or  services  to  a  customer  are  accounted  for  by  analogy  to  International  Accounting  Standards  20,  Accounting  for  Grants  and  Disclosure  of
Government Assistance, or IAS 20. Under IAS 20, the Company recognizes grant funding in the statements of operations as a reduction to research and development
expense as the related costs are incurred to meet those obligations over the grant period. The Company adopted this policy in 2018. For the years ended December 31,
2023  and  December  31,  2022,  the  Company  recognized  approximately  $9.3  million  and  $5.6  million,  respectively,  in  the  statements  of  operations  as  a  reduction  to
research  and  development  expense.  Grant  funding  payments  received  in  advance  of  research  and  development  expenses  incurred  are  recorded  as  deferred  grant
funding liability in the Company's consolidated balance sheets.

Use of Estimates

The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets

and liabilities and the disclosure of contingent assets and

F-10

liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions
reflected in these consolidated financial statements include, but are not limited to, management's judgments with respect to its revenue arrangement, liability related to
the  sale  of  future  royalties,  valuation  of  stock-based  awards  and  the  accrual  of  research  and  development  expenses.  Estimates  are  periodically  reviewed  in  light  of
changes in circumstances, facts and experience. Actual results could differ from those estimates and could materially affect the reported amounts of assets, liabilities
and future operating results.

Liability Related to the Sale of Future Royalties

In December 2023, the Company entered into a royalty interest financing agreement with United in Endeavor, or United, pursuant to which the Company sold to
United  an  interest  in  royalty  and  milestone  payments  the  Company  receives  based  on  net  sales  of  XACIATO.  The  Company  received  $5.0  million  from  United  in
connection with entering into the royalty interest financing agreement. The Company evaluated the terms of the royalty interest financing agreement and concluded that
its features were similar to those of a debt instrument. The Company recognized the $5.0 million it received as a liability on its consolidated balance sheet because the
Company agreed to make payments to United until such time that United has received aggregate payments equaling a 12% internal rate of return on the $5.0 million.
Interest expense for the liability related to the sale of future royalties is recognized using the effective interest rate method over the expected term of the royalty interest
financing agreement.

The liability related to the sale of future royalties and related interest expense are based on current estimates of future royalties, which estimates are based on
forecasts of XACIATO net sales. The Company periodically assesses the forecasted net sales and to the extent the amount or timing of estimated royalty payments are
materially  different  than  previous  estimates,  the  Company  will  account  for  any  such  change  by  adjusting  the  liability  related  to  the  sale  of  future  royalties  and
prospectively recognizing the related non-cash interest expense.

In connection with the royalty investment financing agreement the Company entered into, the Company issued a warrant to purchase up to an aggregate of
5.0 million shares of the Company's common stock. The warrant was allocated a relative fair value of approximately $0.8 million using a Black-Scholes option pricing
model. The $0.8 million relative fair value of the warrant was recorded as a debt discount with an offset to additional paid in capital on the 2023 consolidated balance
sheet as the warrants were deemed to be equity classified.

Risks and Uncertainties

The Company will require approvals from the FDA, or foreign regulatory agencies prior to being able to sell any products. The Company received approval from
the FDA for XACIATO in December 2021. There can be no assurance that the Company’s current or future product candidates will receive the necessary approvals. If
the  Company  is  denied  regulatory  approval  of  its  product  candidates,  or  if  approval  is  delayed,  it  may  have  a  material  adverse  impact  on  the  Company’s  business,
results of operations and its financial position.

The Company is subject to a number of risks similar to other life science companies, including, but not limited to, risks related to the ability to license product
candidates, successfully develop product candidates, successfully commercialize approved products or enter into strategic relationships with third parties who are able
to  successfully  commercialize  approved  products,  raise  additional  capital,  compete  with  other  products,  and  protect  proprietary  technology.  As  a  result  of  these  and
other factors and the related uncertainties, there can be no assurance of the Company’s future success.

Concentration of Credit Risk

The  Company  maintains  cash  balances  at  various  financial  institutions  and  such  balances  commonly  exceed  the  $250,000  amount  insured  by  the  Federal
Deposit Insurance Corporation. The Company also maintains money market funds at various financial institutions which are not federally insured although are invested
primarily in the U.S. The Company has not experienced any losses in such accounts and management believes that the Company does not have significant risk with
respect to such cash and cash equivalents.

Fair Value of Financial Instruments

GAAP  defines  fair  value  as  the  price  that  would  be  received  for  an  asset  or  the  exit  price  that  would  be  paid  to  transfer  a  liability  in  the  principal  or  most
advantageous market in an orderly transaction between market participants on the measurement date, and also establishes a fair value hierarchy which requires an
entity to maximize the use of

F-11

observable inputs, where available. The three-level hierarchy of valuation techniques established to measure fair value is defined as follows:

• Level 1: inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

• Level  2:  inputs  other  than  Level  1  that  are  observable,  either  directly  or  indirectly,  such  as  quoted  prices  in  active  markets  for  similar  assets  and  liabilities,
quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable
market data for substantially the full term of assets or liabilities.

• Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following tables present the classification within the fair value hierarchy of financial assets and liabilities that are remeasured on a recurring basis as of
December 31, 2023  and  December  31,  2022.  There  were  no  financial  assets  or  liabilities  that  were  remeasured  using  a  quoted  price  in  active  markets  for  identical
assets (Level 2) as of December 31, 2023.

Revenue Recognition

Under Accounting Standards Codification Topic 606, or ASC 606, the Company recognizes revenue when it transfers promised goods or services to customers
in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. To determine revenue recognition for contracts
with customers, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii)
determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company
satisfies its performance obligations. At contract inception, the Company assesses the goods or services agreed upon within each contract, assesses whether each
good  or  service  is  distinct,  and  determines  those  that  are performance  obligations.  The  Company  then  recognizes  as  revenue  the  amount  of  the  transaction  price
allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

In a contract with multiple performance obligations, the Company develops estimates and assumptions that require judgment to determine the underlying stand-
alone selling price for each performance obligation, which determines how the transaction price is allocated among the performance obligations. The estimation of the
stand-alone  selling  price(s)  may  include  estimates  regarding  forecasted  revenues  or  costs,  development  timelines,  discount  rates,  and  probabilities  of  technical  and
regulatory  success.  The  Company  evaluates  each  performance  obligation  to  determine  if  it  can  be  satisfied  at  a  point  in  time  or  over  time.  Any  change  made  to
estimated progress towards completion of a performance obligation and, therefore, revenue recognized will be recorded as a change in estimate. In addition, variable
consideration must be evaluated to determine if it is constrained and, therefore, excluded from the transaction price.

Collaboration Revenues. The Company enters into collaboration and licensing agreements under which it out-licenses certain rights to its products or product
candidates to third parties. The terms of these arrangements typically include payment of one or more of the following to the Company: non-refundable, up-front license
fees; development, regulatory and/or commercial milestone payments; and royalties on net sales of licensed products. To date, the Company has not recognized any
collaboration revenues.

License Fee Revenue. If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in a
contract, the Company recognizes revenues from non-refundable, upfront fees allocated to the license when the license is transferred to the customer and the customer
is able to use

F-12

and benefit from the license. For licenses bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to
determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for
purposes of recognizing revenue from non-refundable, upfront fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts
the  measure  of  performance  and  related  revenue  recognition.  To  date,  the  Company  has  recognized  $11.0  million  in  license  fee  revenue,  $10.0  million  of  which
represents the upfront payment under its license agreement for XACIATO and $1.0 million of which represents the payment required by the first amendment to such
license agreement entered into in July 2023.

Royalties. For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and for which the license is deemed
to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance
obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has recognized approximately $7,900 in
royalty revenue.

Product Supply. Arrangements that include a promise for future supply of product for commercial supply at the licensee’s discretion are generally considered as
options. The Company assesses if these options provide a material right to the licensee and if so, they are accounted for as separate performance obligations. The
Company evaluates whether it is the principal or agent in the arrangement. The evaluation is based on the degree the Company controls the specified product at any
time before transfer to the customer. Revenues are recognized on a gross basis if the Company is in the capacity of principal and on a net basis if the Company is in the
capacity of an agent. To date, the Company has recognized approximately $205,000 in revenue along with $201,000 in other expense attributed to the cost of revenue
associated  with  its  product  supply  arrangement  for  XACIATO,  which  is  recorded  in  other  income  in  the  Company's  2023  consolidated  statement  of  operations  and
comprehensive loss. That arrangement was terminated effective December 14, 2023 and the Company will not recognize product supply revenue associated with that
agreement in the future.

Bayer  License.  In  2020,  the  Company  entered  into  a  license  agreement  with  Bayer  Healthcare  LLC,  or  Bayer,  regarding  the  further  development  and
commercialization of Ovaprene in the U.S. and received a $1.0 million upfront non-refundable license fee payment from Bayer (See Note 3, Strategic Agreements). The
$1.0 million upfront payment is recorded as deferred license revenue in the Company's consolidated balance sheets at December 31, 2023 and December 31, 2022.
Bayer, in its sole discretion, has the right to make the license effective by paying the Company an additional $20.0 million. The Company concluded that there was one
significant  performance  obligation  related  to  the  $1.0  million  upfront  payment:  a  distinct  license  to  commercialize  Ovaprene  effective  upon  the  receipt  of  the
$20.0 million fee. The $1.0 million upfront payment will be recorded as license revenue at the earlier of (i) the point in time the Company receives the $20.0 million fee,
the license is transferred to Bayer and Bayer is able to use and benefit from the license and (ii) the termination of the agreement. To date, neither of the foregoing has
occurred.

Under  its  license  agreement  with  Bayer,  the  Company  will  also  be  entitled  to  receive  (a)  milestone  payments  totaling  up  to  $310.0  million  related  to  the
commercial sales of Ovaprene, if all such milestones are achieved, (b) tiered royalties starting in the low double digits based on annual net sales of Ovaprene during a
calendar year, subject to customary royalty reductions and offsets, and (c) a percentage of sublicense revenue.

Milestone Payments.  At  the  inception  of  each  arrangement  in  which  the  Company  is  a  licensor  and  that  includes  developmental,  regulatory  or  commercial
milestones, the Company evaluates whether achieving the milestones is considered probable and estimates the amount to be included in the transaction price using the
most  likely  amount  method.  If  it  is  probable  that  a  significant  revenue  reversal  would  not  occur,  the  associated  milestone  value  is  included  in  the  transaction  price.
Potential future milestone payments not within the Company's control, such as where achievement of the specified milestone depends on activities of a third party or
regulatory  approval,  are  not  considered  probable  of  being  achieved  until  the  specified  milestone  occurs.  As  of  December  31,  2023,  the  Company  has  recognized
$1.8 million of milestone payment revenues.

Potential  future  payments  for  variable  consideration,  such  as  commercial  milestones,  will  be  recognized  when  it  is  probable  that,  if  recorded,  a  significant

reversal will not take place. Potential future royalty payments will be recorded as revenue when the associated sales occur (See Note 3, Strategic Agreements).

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in other non-current assets as right-of-use, or ROU, lease

assets, current portion of lease liabilities, and long-term lease liabilities on the Company's consolidated balance sheets.

F-13

ROU lease assets represent the Company's right to use an underlying asset for the lease term and lease obligations represent the Company's obligation to
make lease payments arising from the lease. Operating ROU lease assets and obligations are recognized at the commencement date based on the present value of
lease payments over the lease term. If the lease does not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available
at the commencement date in determining the present value of lease payments. The ROU lease asset also includes any lease payments made and excludes lease
incentives. The Company's lease terms may include options to extend or terminate the lease and the related payments are only included in the lease liability when it is
reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term (See Note
10, Leased Properties).

Segment Reporting

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief
operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess performance. Its chief operating decision maker is
the chief executive officer. The Company has one operating segment, women’s health.

Australian Research and Development Tax Incentive Program

The  Company  is  eligible  under  the  Australian  Research  and  Development  Tax  Incentive  Program,  or  the  Tax  Incentive,  to  receive  a  cash  refund  from  the
Australian Taxation Office for eligible research and development expenditures. To be eligible, the Company must have revenue of less than AUD $20.0 million during
the reimbursable period and cannot be controlled by income tax exempt entities. Grants received by the Company that do not require the transfer of goods or services
to a customer are accounted for by analogy to IAS 20. Under IAS 20, the Company recognizes the Tax Incentive as a reduction to research and development expense
when there is reasonable assurance that the Tax Incentive will be received, the relevant expenditure has been incurred, and the amount can be reliably measured. The
Company classifies its estimate for the Tax Incentive as other current assets on its consolidated balance sheets. For the years ended December 31, 2023 and 2022, the
Company  recognized  approximately  $0.6  million  and  approximately  $1.6  million,  respectively,  as  a  reduction  to  research  and  development  expense  for  expenses
incurred  that  it  believes  are  eligible  for  the  Tax  Incentive.  At  December  31,  2023  and  2022,  the  Company  recorded  a  receivable  for  the  estimated  Tax  Incentive  of
approximately $0.6 million and $1.6 million, respectively, in other receivables on the accompanying consolidated balance sheets.

Research and Development Costs

Research and development expenses consist of expenses incurred in performing research and development activities, including compensation and benefits for
full-time research and development employees, an allocation of facilities expenses, overhead expenses, manufacturing process-development and scale-up activities,
fees paid to clinical and regulatory consultants, clinical trial and related clinical trial manufacturing expenses, fees paid to contract research organizations, or CROs, and
investigative  sites,  transaction  expenses  incurred  in  connection  with  the  expansion  of  the  product  portfolio  through  acquisitions  and  license  and  option  agreements,
milestone  payments  incurred  or  probable  to  be  incurred  for  the  Company's  in-licensing  arrangements,  payments  to  universities  under  the  Company’s  license
agreements and other outside expenses. Research and development costs are expensed as incurred. Nonrefundable advance payments, if any, for goods and services
used in research and development are recognized as an expense as the related goods are delivered or services are performed.

Patent Costs

The Company expenses all costs as incurred in connection with patent applications (including direct application fees, and the legal and consulting expenses

related to making such applications) and such costs are included in general and administrative expenses in the consolidated statements of operations.

Net Loss Per Share

Basic net loss attributable to common stockholders per share is calculated by dividing the net loss by the weighted average number of shares of common stock
outstanding during the period without consideration of common stock equivalents. Since the Company was in a loss position for all periods presented, diluted net loss
per share is the same as basic net loss per share for all periods presented as the inclusion of all potential dilutive securities would have been antidilutive.

There were stock options exercisable into 9,463,556 and 6,612,554 shares of common stock outstanding at December 31, 2023 and 2022, respectively. There

were warrants exercisable into 15,006,500 and 1,381,015 shares

F-14

of common stock outstanding at December 31, 2023 and 2022, respectively. These securities were not included in the computation of diluted loss per share because
they are antidilutive, but they could potentially dilute earnings (loss) per share in future years.

Stock-Based Compensation

The Company records compensation expense for all stock-based awards granted based on the fair value of the award at the time of grant. The Company uses
the  Black-Scholes  Pricing  Model  to  determine  the  fair  value  of  each  of  the  awards  which  considers  factors  such  as  expected  term,  the  volatility  of  the  Company's
common  stock,  risk  free  interest  rate,  and  dividend  yield.  Due  to  the  limited  history  of  the  Company,  the  simplified  method  was  utilized  in  order  to  determine  the
expected term of the awards. The Company compared U.S. Treasury Bills in determining the risk-free interest rate appropriate given the expected term. The Company
has not established and has no plans to establish, a dividend policy, and the Company has not declared, and has no plans to declare dividends in the foreseeable future
and thus no dividend yield was determined necessary in the calculation of fair value.

Income Taxes

The Company accounts for income taxes using the asset and liability method in accordance with FASB ASC 740, Income Taxes. Under this method, deferred
income  taxes  are  provided  to  reflect  the  tax  consequences  in  future  years  of  differences  between  the  tax  basis  of  assets  and  liabilities  and  their  financial  reporting
amounts  based  on  enacted  tax  laws  and  statutory  tax  rates  applicable  to  the  periods  in  which  the  differences  are  expected  to  affect  taxable  income.  Valuation
allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company follows the two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition
by determining if the weight of available evidence indicates it is more likely than not, that the position will be sustained on audit, including resolution of related appeals
or  litigation  processes,  if  any.  The  second  step  is  to  measure  the  tax  benefit  as  the  largest  amount,  which  is  more  than  50%  likely  of  being  realized  upon  ultimate
settlement.  The  Company  considers  many  factors  when  evaluating  and  estimating  the  Company's  tax  positions  and  tax  benefits,  which  may  require  periodic
adjustments. At each of December 31, 2023 and 2022, the Company did not record any liabilities for uncertain tax positions.

During  each  of  2023  and  2022,  the  Company  recorded  no  provision  for  income  taxes.  Management  evaluated  the  Company’s  tax  positions  and,  as  of
December 31, 2023 and 2022, the Company had approximately $2.6 million and $2.3 million of unrecognized benefits, respectively. The tax years 2020 to 2022 and
2019 to 2022 remain open to examination by federal and state taxing authorities, respectively, while the statute of limitations for U.S. net operating losses generated
remain open beginning in the year of utilization.

Indemnification Obligations

As permitted under Delaware law, the Company has entered into indemnification agreements with its officers and directors that provide that the Company will
indemnify its directors and officers for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by such director or officer in any
action or proceeding arising out of their service as a director and/or officer. The term of the indemnification is for the officer’s or director’s lifetime. During the year ended
December 31, 2023, the Company did not experience any losses related to those indemnification obligations. The Company does not expect significant claims related
to these indemnification obligations, and consequently, has concluded the fair value of the obligations is not material. Accordingly, as of December 31, 2023 and 2022,
no amounts have been accrued related to such indemnification provisions.

3.    STRATEGIC AGREEMENTS

Strategic Agreements for Product Commercialization

Organon Exclusive License Agreement

In  March  2022,  the  Company  entered  into  an  exclusive  license  agreement  with  Organon  which  became  effective  in  June  2022,  whereby  Organon  licensed
exclusive  worldwide  rights  to  develop,  manufacture  and  commercialize  XACIATO  and  other  future  intravaginal  or  urological  products  for  human  use  formulated  with
clindamycin  that  rely  on  intellectual  property  controlled  by  the  Company.  In  July  2022,  the  Company  received  a  $10.0  million  non-refundable  and  non-creditable
payment from Organon, which was recorded as license fee revenue. In July 2023, the Company received a $1.0 million payment from Organon in connection with the
amendment to the license agreement the parties entered into, which was also recorded as license fee revenue. In the fourth quarter of

F-15

2023,  in  connection  with  the  first  commercial  sale  in  the  U.S.  of  XACIATO  in  accordance  with  the  license  agreement,  as  amended,  the  Company  received  the
$1.8 million milestone payment from Organon.

Under  the  terms  of  the  license  agreement,  as  amended,  the  Company  is  entitled  to  receive  tiered  double-digit  royalties  based  on  net  sales  and  up  to

$180.0 million in tiered commercial sales milestones and regulatory milestones. Royalty payments will be subject to customary reductions and offsets.

At the inception of the license agreement, the Company concluded that the transaction price was $10.0 million and should not include the variable consideration
related to unachieved development, regulatory, commercial milestones and future sales-based royalty payments. This consideration was determined to be constrained
as it is probable that the inclusion of such variable consideration could result in a significant reversal in cumulative revenue. The Company re-evaluates the transaction
price at each reporting period as uncertain events are resolved and other changes in circumstances occur. For the year ended December 31, 2023, the transaction
price was updated to $11.0 million.

The Company will recognize any consideration related to sales-based payments, including milestones and royalties which relate predominantly to the license
granted, at the later of (i) when or as the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been
satisfied (or partially satisfied).

The  Company  was  responsible  for  regulatory  interactions  and  for  providing  product  supply  on  an  interim  basis  until  Organon  assumed  such  responsibilities,
which occurred in December 2023. Prior to that time, Organon purchased all of its product requirements of XACIATO from the Company at a transfer price equal to the
Company's manufacturing costs plus a single-digit percentage markup.

Unless terminated earlier, the agreement will expire on a product-by-product and country-by-country basis upon expiration of the applicable royalty period for
each licensed product. In addition to customary termination rights for both parties, following the first anniversary of the effective date of the agreement, Organon may
terminate the agreement in its entirety or on a country-by-country basis at any time in Organon's sole discretion on 120 days' advance written notice.

Bayer HealthCare License Agreement

In January 2020, the Company entered into a license agreement with Bayer, regarding the further development and commercialization of Ovaprene in the U.S.
The Company received a $1.0 million upfront non-refundable license fee payment from Bayer and Bayer agreed to support the Company in development and regulatory
activities  by  providing  the  equivalent  of  two  experts  to  advise  the  Company  in  clinical,  regulatory,  preclinical,  commercial,  CMC  and  product  supply  matters.  The
Company  is  responsible  for  the  pivotal  trial  for  Ovaprene  and  for  its  development  and  regulatory  activities  and  has  product  supply  obligations.  Bayer,  in  its  sole
discretion,  has  the  right  to  make  the  license  effective  by  paying  the  Company  an  additional  $20.0  million,  referred  to  as  the  $20  million  fee.  After  payment  of  the
$20  million  fee,  Bayer  will  be  responsible  for  the  commercialization  of  Ovaprene  for  human  contraception  in  the  U.S.  Such  license  would  be  exclusive  as  to  the
commercialization of Ovaprene for human contraception in the U.S. and co-exclusive with the Company with regard to development.

The  Company  concluded  there  was  one  significant  performance  obligation  related  to  the  $1.0  million  upfront  payment:  a  distinct  license  to  commercialize
Ovaprene effective upon the receipt of the $20.0 million fee. The $1.0 million upfront payment will be recorded as license revenue at the earlier of (i) the point in time
the  Company  receives  the  $20.0  million  fee,  the  license  is  transferred  to  Bayer  and  Bayer  is  able  to  use  and  benefit  from  the  license  and  (ii)  the  termination  of  the
agreement.  As  of  December  31,  2023,  neither  of  the  foregoing  had  occurred.  The  $1.0  million  payment  is  recorded  as  long-term  deferred  license  revenue  in  the
Company's consolidated balance sheets at December 31, 2023 and 2022.

If  Bayer  elects  to  make  the  license  effective,  the  Company  will  be  entitled  to  receive  (a)  a  milestone  payment  in  the  low  double-digit  millions  upon  the  first
commercial  sale  of  Ovaprene  in  the  U.S.  and  escalating  milestone  payments  based  on  annual  net  sales  of  Ovaprene  during  a  calendar  year,  totaling  up  to  $310.0
million  if  all  such  milestones,  including  the  first  commercial  sale,  are  achieved,  (b)  tiered  royalties  starting  in  the  low  double  digits  based  on  annual  net  sales  of
Ovaprene during a calendar year, subject to customary royalty reductions and offsets, and (c) a percentage of sublicense revenue.

The  initial  term  of  the  agreement,  which  is  subject  to  automatic  renewal  terms,  continues  until  the  later  of  the  expiration  of  any  valid  claim  covering  the

manufacture, use, sale or import of Ovaprene in the U.S. or 15 years from

F-16

the first commercial sale of Ovaprene in the U.S. In addition to customary termination rights for both parties, Bayer may terminate the agreement at any time on 90
days' notice and the agreement will automatically terminate if the Company does not receive the $20.0 million fee if and when due.

Strategic Agreements for Pipeline Development

Douglas License Agreement / The University of Manchester Stand-by Direct License Arrangement

In August 2023, the Company entered into a license agreement with Douglas Pharmaceuticals Limited, or Douglas, under which the Company acquired the
exclusive rights to develop and commercialize a lopinavir and ritonavir combination soft gel vaginal insert for the treatment of cervical intraepithelial neoplasia (CIN) and
other HPV-related pathologies, and an agreement with The University of Manchester, pursuant to which The University of Manchester consented to Douglas' sublicense
to the Company of certain rights it previously granted to Douglas and agreed to grant the Company a direct license to such rights if its license agreement with Douglas
is  terminated.  Under  the  Company's  agreement  with  Douglas,  it  received  an  exclusive,  royalty-bearing  license  to  research,  develop  and  commercialize  the  licensed
intellectual  property  in  the  United  States  for  the  treatment  or  prevention  of  all  indications  for  women  in  female  reproductive  health.  The  Company  is  entitled  to
sublicense the rights granted to it under the agreement.

amended the License Agreement.

Under the terms of the License Agreement, the Company paid clinical and regulatory development milestones of $300,000 in the aggregate to MilanaPharm,

worldwide net sales of licensed products and processes.

Hammock assigned and transferred to the Company all of its right, title and interest in and to the MilanaPharm license agreement and agreed to cooperate to
transfer to the Company all of the data, materials and the licensed technology in its possession pursuant to a technology transfer plan. Hammock is eligible to receive
up to $1.1 million in the aggregate upon achievement of certain clinical and regulatory development milestones, $850,000 of which has been paid as of December 31,
2023.

In May 2018, the Company acquired Pear Tree Pharmaceuticals, Inc., or Pear Tree, to secure exclusive, sublicensable, worldwide rights under certain patents
and  know-how  to  develop  and  commercialize  a  proprietary  formulation  of  tamoxifen  for  vaginal  administration.  This  acquisition  led  to  the  Company's  DARE-VVA1
program.

Under the terms of the merger agreement, the Company agreed to pay the former stockholders of Pear Tree: (a) up to $15.5 million in the aggregate upon
achievement of certain clinical development and regulatory milestones by licensed products, and (b) up to $47.0 million in the aggregate upon achievement of certain
commercial  milestones  by  licensed  products.  Additionally,  the  former  stockholders  of  Pear  Tree  are  eligible  to  receive  tiered  royalties  based  on  single-digit  to  low
double-digit percentages of annual net sales of licensed products by the Company or its affiliates, subject to customary reductions and offsets, and a portion of royalties
the Company receives from sublicensees. Both the milestone and royalty payments may be made, in the Company's sole discretion, in cash or in shares of its common
stock in accordance with the terms of the merger agreement. Under the merger agreement, in addition to customary royalty reductions and offsets, royalty payments
and payments based on income received from sublicensees of licensed products made by the Company to Pear Tree's licensors are creditable against all royalty and
sublicense revenue share payments payable to the former stockholders of Pear Tree.

The Company agreed to pay licensors of Pear Tree (a) up to approximately $3.2 million in the aggregate upon achievement of certain clinical development,
regulatory and commercial milestones by each licensed product, and (b) semi-annual royalties based on a single-digit percentage of net sales of licensed products by
the Company or

F-18

its affiliates, subject to customary reductions and offsets, or a portion of any royalties the Company or its affiliates receives from sublicensees, and a low double-digit
percentage  of  all  sublicensing  fees  or  other  lump  sum  payments  or  compensation  the  Company  receives  from  sublicensees,  subject  to  customary  exclusions.  The
milestone payments to the licensors of Pear Tree may be made, in the Company's sole discretion, in cash or in shares of its common stock in accordance with the
terms of the license agreements. Portions of certain milestone payments made to Pear Tree's licensors may be creditable against royalty payments due to Pear Tree's
licensors.

Catalent JNP License Agreement

In April 2018, the Company entered into an exclusive license agreement with Catalent JNP, Inc., or Catalent, under which Catalent granted the Company (a) an
exclusive, royalty-bearing worldwide license under certain patent rights, either owned by or exclusively licensed to Catalent, to make, have made, use, have used, sell,
have sold, import and have imported products and processes, and (b) a non-exclusive, royalty-bearing worldwide license to use certain technological information owned

granted to it under this agreement.

Under the terms of the license agreement, the Company paid a $250,000 non-creditable upfront license fee to Catalent in connection with the execution of the
agreement and will pay a $100,000 annual license maintenance fee on each anniversary of the date of the agreement. The annual maintenance fee will be creditable
against royalties and other payments due to Catalent in the same calendar year but may not be carried forward to any other year. Catalent is eligible to receive up to (a)
$13.5 million in the aggregate in payments based on the achievement of specified development and regulatory milestones, $1.0 million of which has been paid as of
December 31, 2023; and (b) up to $30.3 million in the aggregate in payments based on the achievement of specified commercial sales milestones for each product or
process  covered  by  the  licenses  granted  under  the  agreement.  Additionally,  Catalent  is  eligible  to  receive  mid  single-digit  to  low  double-digit  royalties  based  on
worldwide net sales of products and processes covered by the licenses granted under the agreement. In lieu of such royalty payments, the Company will pay Catalent a
low double-digit percentage of all sublicense income the Company receives for the sublicense of rights under the agreement to a third party.

Adare Development and Option Agreement

In  March  2018,  the  Company  entered  into  an  exclusive  development  and  option  agreement  with  Adare  Pharmaceuticals  USA,  Inc.,  or  Adare,  for  the
development and potential exclusive worldwide license of injectable formulations of etonogestrel for contraceptive protection over 6-month and 12-month periods (which
the  Company  refers  to  as  DARE-204  and  DARE-214,  respectively).  The  agreement,  as  amended,  provides  the  Company  with  an  option  to  negotiate  an  exclusive,
worldwide, royalty-bearing license, with rights to sublicense, for the programs if the Company funds the conduct of specified development work. The Company has no
obligation to exercise its option.

SST License and Collaboration Agreement

In  February  2018,  the  Company  entered  into  a  license  and  collaboration  agreement  with  Strategic  Science  & Technologies-D  LLC  and  Strategic  Science  &
Technologies,  LLC,  referred  to  collectively  as  SST,  under  which  the  Company  received  an  exclusive,  royalty-bearing,  sublicensable  license  to  develop  and
commercialize,  in  all  countries  and  geographic  territories  of  the  world,  for  all  indications  for  women  related  to  female  sexual  dysfunction  and/or  female  reproductive
health, including treatment of female sexual arousal disorder and/or female sexual interest/arousal disorder, or the Field of Use, SST’s topical formulation of Sildenafil
Cream, 3.6% as it existed as of the effective date of the agreement, or any other topically applied pharmaceutical product containing sildenafil or a salt thereof as a
pharmaceutically active ingredient, alone or with other active ingredients, but specifically excluding any product containing ibuprofen or any salt derivative of ibuprofen,
or the Licensed Products.

SST will be eligible to receive payments of up to $18.0 million in the aggregate upon achievement of certain clinical and regulatory milestones in the U.S. and
worldwide, and up to $100.0 million in the aggregate upon achievement of certain commercial sales milestones. If the Company enters into strategic development or
distribution partnerships related to the Licensed Products, additional milestone payments would be due to SST. Additionally, SST

F-19

is eligible to receive tiered royalties based on percentages of annual net sales of licensed products in the single-digit to mid double-digits subject to customary royalty
reductions and offsets, and a percentage of sublicense revenue.

ADVA-Tec License Agreement

In March 2017, the Company entered into a license agreement with ADVA-Tec, Inc., or ADVA-Tec, under which the Company was granted the exclusive right to

develop and commercialize Ovaprene for human contraceptive use worldwide.

Under  the  terms  of  the  license  agreement,  the  Company  will  pay  ADVA-Tec  (a)  up  to  $14.6  million  in  the  aggregate  based  on  the  achievement  of  specified
development  and  regulatory  milestones,  $1.2  million  of  which  has  been  paid;  and  (b)  up  to  $20.0  million  in  the  aggregate  based  on  the  achievement  of  certain
worldwide net sales milestones.

sale of a licensed product that represents an upfront payment or license fee due on or around the effective date of the sublicense, ADVA-Tec is eligible to receive a
single-digit percentage of that sublicense revenue.

6.    VENDOR CONCENTRATION

The Company had one major vendor that accounted for approximately 21% and 10% of the Company's research and development expenditures for the years
ended  December  31,  2023  and  2022,  respectively.  The  same  vendor  also  accounted  for  approximately  0%  and  17%  of  the  Company's  total  accounts  payable  and
accrued  expenses  as  of  December  31,  2023  and  2022,  respectively.  The  Company  continues  to  maintain  its  relationship  with  this  vendor  and  anticipates  incurring
significant expenses with this vendor over the next 12 months.

The  Company  has  evaluated  the  positive  and  negative  evidence  bearing  upon  the  realizability  of  its  deferred  tax  assets.  Under  applicable  accounting
standards, management has considered the Company’s history of losses and concluded that it is more likely than not the Company will not recognize the benefits of
federal  and  state  deferred  tax  assets.  Accordingly,  a  valuation  allowance  of  $112.3  million  and  $104.2  million  was  established  at  December  31,  2023  and  2022,
respectively,  to  offset  the  net  deferred  tax  assets.  When  and  if  management  determines  that  it  is  more  likely  than  not  that  the  Company  will  be  able  to  utilize  the
deferred tax assets prior to their expiration, the valuation allowance may be reduced or eliminated.

F-21

The increase in valuation allowance of approximately $8.0 million and $4.5 million for the years ending December 31, 2023 and 2022, respectively, is primarily

related to an increase in net operating losses generated during the year.

The Company has U.S. federal net operating loss, or NOL, carryforwards available at December 31, 2023 of approximately $314.9 million of which $1.2 million
begin expiring in 2024 unless previously utilized and $117.7 million that do not expire. The Company has state NOL carryforwards of $294.1 million that begin expiring
in  2031  unless  previously  utilized.  The  Company  has  U.S.  federal  research  credit  carryforwards  available  at  December  31,  2023  of  approximately  $10.4  million  that
begin  expiring  in  2027  unless  previously  utilized.  The  Company  has  state  research  credit  carryforwards  of  $2.7  million  of  which  $0.2  million  begin  expiring  in  2024
unless  previously  utilized.  These  federal  and  state  research  and  development  credits  are  subject  to  a  20%  reserve  under  FASB  ASC  740.  The  difference  between
federal and state NOL carryforwards is primarily due to previously expired state NOL carryforwards.

Utilization of the NOL and research and development credit carryforwards may be subject to a substantial annual limitation under Sections 382 and 383 of the
Internal Revenue Code of 1986 due to ownership change limitations that have occurred previously or that could occur in the future. These ownership changes may limit
the amount of NOL and research and development credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. The Company
has not yet completed an evaluation of ownership changes. To the extent an ownership change occurs, the NOL and credit carryforwards and other deferred tax assets
may be subject to limitations.

A reconciliation of the beginning and ending amount of uncertain tax benefits is as follows (in thousands):

Included in the balance of uncertain tax benefits at December 31, 2023 are $2.6 million of tax benefits that, if recognized, would result in a reduction of the
gross deferred tax asset, offset fully by valuation allowance and have no net impact on the financial statements. The Company anticipates that no material amounts of
unrecognized tax benefits will be settled within 12 months of the reporting date.

The  Company's  policy  is  to  record  estimated  interest  and  penalties  related  to  uncertain  tax  benefits  as  income  tax  expense.  As  of  December  31,  2023  and

2022, the Company had no accrued interest or penalties recorded related to uncertain tax positions.

The tax years 2019 through 2023 remain open to examination by major taxing jurisdictions to which the Company is subject, which are primarily in the U.S. The

statute of limitations for U.S. net operating losses utilized in future years will remain open beginning in the year of utilization.

No additional provision has been made for U.S. income taxes related to undistributed foreign earnings of the Company’s wholly-owned Australian subsidiary or
for unrecognized deferred tax liabilities for temporary differences related to investments in subsidiaries. As such, earnings are expected to be permanently reinvested,
the  investments  are  permanent  in  duration,  or  the  Company  has  estimated  that  no  additional  tax  liability  will  arise  as  a  result  of  the  distribution  of  such  earnings.  A
liability could arise if amounts are distributed by the subsidiary or if the subsidiary is ultimately disposed. It is not practical to estimate the additional income taxes, if any,
related to permanently reinvested earnings. There are no unremitted earnings as of December 31, 2023.

Common Stock Warrants

December 2023 Warrants

In connection with the royalty interest financing agreement the Company entered into in December 2023, the Company issued a warrant to purchase up to an
aggregate of 5,000,000 shares of the Company's common stock. The warrant has a term of five years from the date of issuance and an exercise price of $0.3467 per
share, subject to customary adjustment for stock splits and similar transactions. A holder (together with its affiliates) may not exercise any portion of the warrant to the
extent that the holder would own more than 4.99% (or, at the election of the holder 9.99%) of the Company's outstanding common stock immediately after exercise. The
warrant includes certain rights in favor of the holder upon a “fundamental transaction” as described in the warrant, including the right of the holder to receive from the
Company or the successor entity an amount of cash equal to the Black-Scholes value (as described in the warrants) of the unexercised portion of the warrant on the
date of the consummation of such fundamental transaction.

The warrant was allocated a value of $0.8 million using a Black-Scholes option pricing model based on the relative fair value method as they were issued with
common stock. The Black-Scholes model used the following assumptions: expected volatility: 85.91%; risk-free interest rate: 4.05%; expected dividend yield: 0%; and
expected term: 5 years. The warrant was deemed to be classified as equity and recorded within additional paid in capital on the 2023 consolidated balance sheet. As of
December 31, 2023, no portion of the warrant has been exercised.

In connection with the registered direct offering completed in September 2023, the Company issued warrants to purchase up to an aggregate of 10,000,000
shares of the Company's common stock. The warrants became exercisable on March 1, 2024, expire March 1, 2029 and have an exercise price of $0.77 per share,
subject to customary adjustment for stock splits and similar transactions. A holder (together with its affiliates) may not exercise any portion of a warrant to the extent that
the holder would own more than 4.99% (or, at the election of the holder 9.99%) of the Company's outstanding common stock immediately after exercise. The warrants
include  certain  rights  in  favor  of  the  holders  upon  a  “fundamental  transaction”  as  described  in  the  warrants,  including  the  right  of  the  holders  to  receive  from  the
Company or the successor entity an amount of cash equal to the Black-Scholes value (as described in the warrants) of the unexercised portion of the warrants on the
date of the consummation of such fundamental transaction.

The warrants were allocated a value of $2.9 million using a Black-Scholes option pricing model based on the relative fair value method as they were issued with
common stock. The Black-Scholes model used the following assumptions: expected volatility: 87.77%; risk-free interest rate: 4.29%; expected dividend yield: 0%; and
expected term: 5.5 years. The warrants were deemed to be classified as equity and recorded within additional paid in capital on the 2023 consolidated balance sheet.
As of December 31, 2023, none of the warrants have been exercised.

February 2018 Warrants

In connection with an underwritten public offering in February 2018, the Company issued to the investors in that offering, warrants exercisable through February
15,  2023  with  an  initial  exercise  price  of  $3.00  per  share.  The  Company  estimated  the  fair  value  of  the  warrants  as  of  February  15,  2018  to  be  approximately
$3.0 million which was recorded in equity as of the grant date. The warrants included a price-based anti-dilution provision, which resulted in automatic reductions to the
exercise price of the warrants in April 2019 and July 2020 to $0.98 per share and to $0.96 per share, respectively.

A summary of warrant activity during the years ended December 31, 2023 and 2022 is presented below:

2014 Employee Stock Purchase Plan

The Company’s 2014 Employee Stock Purchase Plan, or the ESPP, became effective in April 2014, but no offering period has been initiated thereunder since

January 2017 and there was no stock-based compensation related to the ESPP for the years ended December 31, 2023 or December 31, 2022.

Amended and Restated 2014 Stock Incentive Plan

The  Amended  and  Restated  2014  Stock  Incentive  Plan,  or  the  Amended  2014  Plan,  provided  for  the  grant  of  stock-based  awards  to  employees,  directors,
consultants  and  advisors.  There  were  2,046,885  shares  of  common  stock  authorized  for  issuance  under  the  Amended  2014  Plan  when  it  was  approved  by  the
Company's stockholders in July 2018. The number of authorized shares increased annually on the first day of each fiscal year by the least of (i) 2,000,000, (ii) 4% of the
number of outstanding shares of common stock on such date, or (iii) an amount determined by the Company’s board of directors. On January 1, 2022, the number of
available  shares  increased  by  2,000,000  to  2,201,855.  As  a  result  of  the  approval  of  the  2022  Plan  (as  defined  below)  by  the  Company's  stockholders  on  June  23,
2022, no further awards have been or will be granted under the Amended 2014 Plan. Outstanding awards previously granted under the Amended 2014 Plan continue to
remain outstanding in accordance with their terms.

2022 Stock Incentive Plan

In  April  2022,  the  Company's  board  of  directors  approved  the  Daré  Bioscience,  Inc.  2022  Stock  Incentive  Plan,  or  the  2022  Plan,  which  was  subsequently

approved by the Company's stockholders on June 23, 2022, and

F-25

became effective as of that date. The 2022 Plan provides for the grant of stock-based incentive awards to employees, directors, consultants, and advisors.

The  number  of  shares  of  common  stock  authorized  for  issuance  under  the  2022  Plan  is  (a)  10,117,305;  plus  (b)  up  to  6,144,682  shares  subject  to  awards

granted under the Amended 2014 Plan or the 2007 Stock Incentive Plan that expire, terminate or are otherwise forfeited on or after June 23, 2022.

Summary of Stock Option Activity

10.     LEASED PROPERTIES

The Company's lease for its corporate headquarters (3,169 square feet of office space) commenced on July 1, 2018. In February 2022, the Company entered

into an amendment to extend the term of the lease for two years such that the term now expires on August 31, 2024.

MBI, a wholly-owned subsidiary the Company acquired in November 2019, leases general office and laboratory space in Lexington, Massachusetts. The lease
for that space commenced on July 1, 2013. In February 2022, the Company entered into an amendment to extend the term of the lease for three years to December 31,
2025, subject to the landlord's right to terminate the lease on December 31, 2023. The extension of the lease in February 2022 resulted in an increase in operating
lease liabilities and ROU assets of approximately $1.0 million. In September 2022, the landlord exercised its option to terminate the lease, resulting in the new lease
term ending on December 31, 2023. The termination of the lease resulted in a reduction of operating lease liabilities and ROU assets of approximately $0.5 million and
$0.5 million, respectively, and a $46,000 gain on the modification of the lease which was included as a reduction to research and development expense for the year
ended December 31, 2022. MBI entered into a new lease for general office space and laboratory space in June 2023 that commenced on November 1, 2023 for three
years, expiring on December 31, 2026, and resulted in an increase in operating lease liabilities and ROU assets of approximately $1.3 million.

MBI previously leased warehouse space in Billerica, Massachusetts, under a lease that commenced on October 1, 2016 and terminated on March 31, 2022.

Under the terms of each lease, the lessee pays base annual rent (subject to an annual fixed percentage increase), plus property taxes, and other normal and
necessary expenses, such as utilities, repairs, and maintenance. The  Company  evaluates  renewal  options  at  lease  inception  and  on  an  ongoing  basis  and  includes
renewal options that it is reasonably certain to exercise in its expected lease terms when classifying leases and measuring lease liabilities. The leases do not require
material variable lease payments, residual value guarantees or restrictive covenants.

The leases do not provide an implicit rate, and therefore the Company uses its incremental borrowing rate as the discount rate when measuring operating lease
liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur at lease commencement to borrow an amount equal to
the lease payments on a collateralized basis over the term of the lease within a particular currency environment. The Company uses an incremental borrowing rate
consisting of the current prime rate plus 200 basis points for operating leases. The depreciable lives of operating leases and leasehold improvements are limited by the
expected lease term.

At December 31, 2023, the Company reported operating lease ROU assets of approximately $1.3 million in other non-current assets, approximately $0.5 million

in current portion of lease liabilities, and approximately $0.9 million in lease liabilities long-term in the consolidated balance sheets.

Total operating lease costs were approximately $0.6 million and $0.6 million for the years ended December 31, 2023 and 2022, respectively. Operating lease
costs consist of monthly lease payments expense, common area maintenance and other repair and maintenance costs and are included in general and administrative
expenses in the consolidated statements of operations.

Cash  paid  for  amounts  included  in  the  measurement  of  operating  lease  liabilities  was  approximately  $0.4  million  and  $0.3  million  for  the  years  ended
December 31, 2023 and 2022, respectively, and these amounts are included in operating activities in the consolidated statements of cash flows. At December 31, 2023,
operating leases had a weighted average remaining lease term of 1.83 years and a weighted average interest rate of 10.27%.

At December 31, 2023, future minimum lease payments under the Company's operating leases are as follows:

11.     SALE OF FUTURE ROYALTIES

On December 21, 2023, the Company entered into a royalty interest financing agreement, or the Royalty Agreement, with United in Endeavour, LLC, or United,
under which United acquired a portion of the Company's royalty interest in XACIATO. The Company received $5.0 million from United when the parties entered into the
Royalty  Agreement  (the  "Initial  Investment"),  and  between  January  1,  2024  and  December  31,  2026,  the  Company  may,  in  its  sole  discretion,  elect  to  receive  three
additional payments (each a "Supplemental Investment") from United of up to an aggregate of $7.0 million, for a total of up to $12.0 million.

Under the Royalty Agreement, the Company agreed to make the following payments to United, until such time when United has received aggregate payments
equaling  a  12%  internal  rate  of  return  (the  “IRR”)  on  the  Initial  Investment  and  each  Supplemental  Investment,  if  any  (the  "Hard  Cap"):  (i)  from  December  21,  2023
through December 31, 2025, 50% of the amount of royalty payments remaining after all amounts that are due and payable and actually paid by the Company to any
licensor or sublicensee on the royalty payments generated and received by the Company on net sales of XACIATO by Organon have been deducted (the “Net Royalty
Payments”), (ii) from January 1, 2026 through December 31, 2029, 75% of the Net Royalty Payments, and (iii) from December 21, 2023 through December 31, 2029,
10% of the amount of milestone payments remaining after all amounts that are due and payable and actually paid by the Company to any licensor or sublicensee on the
milestone payments generated and received by the Company on net sales of XACIATO by Organon have been deducted. After December 31, 2029, the Company will
be required to make certain additional payments to United to the extent United has not received payments equaling the Hard Cap by December 31, 2029, December
31, 2033, and December 31, 2034, respectively. In addition, if United has not received payments equaling the Hard Cap by December 31, 2035 and the Company has
other sources of assets or income besides XACIATO sufficient to complete such payments, the Company has agreed to pay United quarterly payments evenly divided
over  a  two-year  term,  such  that  United  will  have  obtained  the  IRR,  taking  into  account  all  other  payments  received  by  United  from  the  Company  under  the  Royalty
Agreement. United’s right to receive payments will terminate when United has received the Hard Cap.

The  Company  evaluated  the  terms  of  the  Royalty  Agreement  and  concluded  that  the  features  of  the  Royalty  Agreement  were  similar  to  those  of  a  debt
instrument. As a result, the Company applied the debt recognition guidance under ASC 470, Debt, and recorded the Initial Investment as a liability related to the sale of
future  royalties  (“Royalty  Obligation”)  on  the  Company's  2023  consolidated  balance  sheet,  which  will  be  amortized  under  the  effective  interest  method  over  the
estimated term of the Royalty Agreement. If the Company elects to receive additional Supplemental Investments, such additional Supplemental Investments will also be
recorded as a liability related to the sale of future royalties when they are received and amortized under the interest method over the estimated remaining term of the
Royalty Agreement. In addition, in accordance with ASC 470, Debt, the Company will account for any royalties received in the future as non-cash royalty revenue in the
consolidated statements of operations as a reduction to the debt balance.

As royalties and milestone payments are received by the Company from Organon and the Company subsequently pays the amounts due to United in respect
thereof in accordance with the Royalty Agreement, the Royalty Obligation will be effectively repaid during the term of the Royalty Agreement. In order to determine the
amortization of the Royalty Obligation, the Company is required to estimate the total amount of future payments to United during the term of the Royalty Agreement.

At  execution  of  the  Royalty  Agreement,  the  Company’s  estimate  of  this  total  interest  expense  resulted  in  an  effective  annual  interest  rate  of  approximately
22.48%. This estimate contains significant assumptions that impact both the amount recorded at execution and the interest expense that will be recognized over the
royalty period. The Company will periodically assess the estimated amounts due and payable to United and to the extent the amount or  timing  of  such  payments  is
materially different than the original estimates, an adjustment will be recorded prospectively to increase or decrease interest expense. There are a number of factors
that  could  materially  affect  XACIATO's  commercial  success,  and  therefore  the  amount  and  timing  of  the  Company's  payments  to  United,  and  correspondingly,  the
amount of interest expense recorded by the Company, most of which are not within the Company’s control. Such factors include, but are not limited to, the capabilities
of Organon and its commitment of sufficient resources to market, distribute and sell the product; timely and adequate commercial supply of the finished product and its
components; perceived superiority of its cure rates compared to other available treatments; patient satisfaction and willingness to use it again and refer it to others;
price pressure given the high level of generic treatments and changes in health care laws and regulations; adequate coverage, pricing and reimbursement from

F-28

third-party payors; and approval of new entrants, including alternative, non-antibiotic treatment options. These factors could result in increases or decreases to both
royalty revenues and interest expense.

Warrants

In connection with entering into the Royalty Agreement, the Company issued to United a warrant (the “Initial Royalty Warrant”) to purchase up to 5,000,000
shares of the Company’s common stock. In addition, for every $1,000,000 of Supplemental Investment, the Company will issue a warrant to purchase 1,000,000 shares
of common stock, for an aggregate of warrants to purchase up to 7,000,000 shares of common stock (collectively the “Additional Royalty Warrants,” and together with
the Initial Royalty Warrant, the “Royalty Agreement Warrants”).

The Royalty Agreement Warrants are exercisable, in full or in part, at any time on or prior to the fifth anniversary of their issuance date at an exercise price of
$0.3467 per share, subject to customary anti-dilution adjustments. The Royalty Agreement Warrants may be exercised for cash, or if at the time of exercise there is no
effective  registration  statement  registering  for  resale  the  shares  underlying  the  Royalty  Agreement  Warrants,  then  in  lieu  of  paying  the  exercise  price  in  cash,  the
holders may elect to exercise on a cashless basis.

The Royalty Agreement Warrants were deemed to be equity classified warrants and recorded under additional paid in capital. The fair value of the Initial Royalty

Warrant was determined to be $0.8 million (Note 8) and was recorded as a debt discount against the Initial Investment.

The following table shows the activity of the Royalty Obligation since the transaction inception through the period indicated:

12.    COMMITMENTS AND CONTINGENCIES

Insurance Financing

In July 2023, the Company obtained financing for director and officer and other insurance premiums. The agreement for such financing assigns to the lender a
first  priority  lien  on  and  a  security  interest  in  the  financed  insurance  policies  and  any  additional  premium  required  in  the  financed  insurance  policies  including  (a)  all
returned or unearned premiums, (b) all additional cash contributions or collateral amounts assessed by the insurance companies in relation to the financed insurance
policies and financed by the lender, (c) any credits generated by the financed insurance policies, (d) dividend payments, and (e) loss payments which reduce unearned
premiums.  If  any  circumstances  exist  in  which  premiums  related  to  any  financed  insurance  policy  could  become  fully  earned  in  the  event  of  loss,  the  lender  will  be
named a loss-payee with respect to such policy.

The total premiums, taxes and fees financed was approximately $0.6 million with an annual interest rate of approximately 8.0%. In consideration of the premium
payment by the lender to the insurance companies or the agent or broker, the Company promised to pay the lender the amount financed plus interest and other charges
permitted  under  the  agreement.  The  Company  will  make  monthly  installment  payments  on  the  financed  amount  through  April  20,  2024.  The  financed  amount  is
recognized as an insurance financing cost included in other current assets and accrued expenses in the Company's consolidated balance sheets. As of December 31,
2023, the Company's remaining obligation under the agreement was approximately $0.3 million.

CRADA with NICHD for the Pivotal Phase 3 Study of Ovaprene

In July 2021, the Company entered into a Cooperative Research and Development Agreement, or the CRADA, with the U.S. Department of Health and Human
Services, as represented by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, or NICHD, for the conduct of a multi-center, non-
comparative, pivotal Phase 3 clinical study of Ovaprene, or the Ovaprene Phase 3. The Ovaprene Phase 3 will be conducted within NICHD’s Contraceptive Clinical Trial
Network  with  NICHD's  contract  research  organization  providing  clinical  coordination  and  data  collection  and  management  services  for  the  Ovaprene  Phase  3.  The
Company and NICHD will each provide medical oversight and final data review and analysis for the Ovaprene Phase 3 and will work

F-29

together  to  prepare  the  final  report  of  the  results  of  the  Ovaprene  Phase  3.  The  Company  is  responsible  for  providing  clinical  supplies  of  Ovaprene,  coordinating
interactions  with  the  FDA,  preparing  and  submitting  supportive  regulatory  documentation,  and  providing  a  total  of  $5.5  million  in  payments  to  NICHD  to  be  applied
toward the costs of conducting the Ovaprene Phase 3. NICHD is responsible for the other costs related to the conduct of the Ovaprene Phase 3. In accordance with the
payment schedule under the CRADA, the Company has made aggregate payments of $5.0 million to NICHD, $3.5 million of which was paid in 2022. The Company's
remaining obligation under the CRADA at December 31, 2023 is $0.5 million.

Legal Proceedings

From time to time, the Company may be involved in various claims arising in the normal course of business. Management is not aware of any material claims,
disputes or unsettled matters that would have a material adverse effect on the Company’s results of operations, liquidity or financial position that the Company has not
adequately provided for in the accompanying consolidated financial statements.

Employment Agreements

Certain executive officers of the Company are entitled to payments if their employment is terminated by the Company without cause, if they resign for good
reason, if their employment agreements are not renewed, or if their employment is terminated by the Company without cause or if they resign for good reason, in each
case, within three months prior to or 12 months following a change in control of the Company. Upon termination by the Company without cause, if they resign for good
reason, if their employment agreements are not renewed, such executives are entitled to receive a payment of an amount equal to either nine or twelve months of base
salary and to receive continuing health benefits coverage for periods equal to either nine or twelve months following the termination of employment or until such officer
is covered under a separate plan from another employer. If their employment is terminated by the Company without cause or if they resign for good reason, in each
case, within three months prior to or 12 months following a change in control of the Company, such executives will be entitled to receive a payment of an amount equal
to either twelve or eighteen months of base salary and target bonus and to receive continuing health benefits coverage for periods ranging between twelve and eighteen
months following the termination of employment. In addition, upon a change in control of the Company, each officer’s outstanding unvested options will fully vest and
accelerate subject to the conditions outlined in such officer’s employment agreement.

Employee Benefit – 401(k) Plan

The Company has a 401(k) retirement plan, or the 401(k) Plan, covering all qualified employees. The 401(k) Plan allows each participant to contribute a portion
of their base wages up to an amount not to exceed an annual statutory maximum. The 401(k) Plan includes a Safe Harbor Plan that provides a Company match up to
4% of salary. The Company made matching contributions of approximately $213,000 and $200,000 during the years ended December 31, 2023 and 2022, respectively.

13.    GRANT AWARDS

NICHD Non-Dilutive Grant Funding

The  Company  has  received  notices  of  awards  and  non-dilutive  grant  funding  from  NICHD  to  support  the  development  of  several  of  its  product  candidates.
NICHD issues notices of awards to the Company for a specified amount, and the Company must incur and track expenses eligible for reimbursement under the award
and  submit  a  detailed  accounting  of  such  expenses  to  receive  payment.  If  the  Company  receives  payments  under  the  award,  the  amounts  of  such  payments  are
recognized in the statements of operations as a reduction to research and development activities as the related costs are incurred to meet those obligations over the
period.

DARE-PTB1

In  August  2020,  the  Company  received  a  notice  of  award  of  a  grant  from  NICHD  to  support  the  development  of  DARE-PTB1.  The  award  of  approximately
$300,000 was to be used for what is referred to as the "Phase I" segment of the project outlined in the Company's grant application. The Phase I segment ended in July
2023. The Company recorded credits to research and development expense for costs related to the NICHD award of approximately $1,000 and $20,000 for the year
ended December 31, 2023 and 2022. The Company received aggregate reimbursements under the award of approximately $216,000 during the grant period which
ended in July 2023. No further funds are available under this award for the Phase I segment.

F-30

In December 2023, the Company received a notice of award of approximately $2.0 million for the "Phase II" segment of the project. The Company recorded no

credits to research and development expense for costs related to the NICHD award for the year ended December 31, 2023.

DARE-LARC1

In September 2021, the Company received a notice of award of a grant from NICHD to support the development of DARE-LARC1. The award in the amount of

Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a
United  States  bank  unless  the  cashless  exercise  procedure  specified  in  Section  2(c)  below  is  specified  in  the  applicable  Notice  of  Exercise. No  ink-original

this  Warrant  resulting  in  purchases  of  a  portion  of  the  total  number  of  Warrant  Shares  available  hereunder  shall  have  the  effect  of  lowering  the  outstanding
number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company

Cashless Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein
is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may also be exercised, in whole or in part, at such time by means of a
“cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A),
where:

(A) = as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is
(1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant
to  Section  2(a)  hereof  on  a  Trading  Day  prior  to  the  opening  of  “regular  trading  hours”  (as  defined  in  Rule  600(b)  of  Regulation  NMS
promulgated  under  the  federal  securities  laws)  on  such  Trading  Day,  (ii)  at  the  option  of  the  Holder,  either  (y)  the  VWAP  on  the  Trading  Day
immediately preceding the date of the applicable Notice of Exercise or (z) the Bid Price of the Common Stock on the Nasdaq Capital Market (the
“Principal Market”) as reported by Bloomberg L.P. (“Bloomberg”) as of the time of the Holder’s execution of the applicable Notice of Exercise if
such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter (including
until two (2) hours after the close of “regular trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the
applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered
pursuant to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;

(B) = the Exercise Price of this Warrant, as adjusted hereunder; and

(X) = the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise

were by means of a cash exercise rather than a cashless exercise.

For  purposes  of  Rule  144(d)  promulgated  under  the  1933  Act,  as  in  effect  on  the  Effective  Date,  it  is  intended  that  the  Warrant  Shares  issued  in  a
Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced,
on the date this Warrant was originally issued pursuant to the Agreement.

“Bid Price” means, as applicable: (i) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the date of the applicable

Exercise Notice if such Exercise Notice is (1) both executed and delivered pursuant to Section 1(a) hereof on a day that is not a

 To be 110% of the closing sale price on the Effective Date.

Trading Day or (2) both executed and delivered pursuant to Section 1(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in
Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) the Bid Price of the Common Stock as of the time
of the Holder’s execution of the applicable Exercise Notice if such Exercise Notice is executed during “regular trading hours” on a Trading Day and is delivered
within two (2) hours thereafter pursuant to Section 1(a) hereof, or (iii) the Closing Sale Price of the Common Stock on the date of the applicable Exercise Notice
if the date of such Exercise Notice is a Trading Day and such Exercise Notice is both executed and delivered pursuant to Section 1(a) hereof after the close of
“regular trading hours” on such Trading Day.

“Trading Day” means, as applicable, (x) with respect to all price or trading volume determinations relating to the Common Stock, any day on which the
Common  Stock  is  traded  on  the  Principal  Market,  or,  if  the  Principal  Market  is  not  the  principal  trading  market  for  the  Common  Stock,  then  on  the  principal
securities  exchange  or  securities  market  on  which  the  Common  Stock  is  then  traded,  provided  that  “Trading  Day”  shall  not  include  any  day  on  which  the
Common Stock is scheduled to trade on such exchange or market for less than 4.5 hours or any day that the Common Stock is suspended from trading during
the  final  hour  of  trading  on  such  exchange  or  market  (or  if  such  exchange  or  market  does  not  designate  in  advance  the  closing  time  of  trading  on  such
exchange or market, then during the hour ending at 4:00:00 p.m., New York time) unless such day is otherwise designated as a Trading Day in writing by the
Holder or (y) with respect to all determinations other than price or trading volume determinations relating to the Common Stock, any day on which The New
York Stock Exchange (or any successor thereto) is open for trading of securities

“VWAP” means, for any security as of any date, the dollar volume-weighted average price for such security on the Principal Market (or, if the Principal
Market is not the principal trading market for such security, then on the principal securities exchange or securities market on which such security is then traded)
during the period beginning at 9:30:01 a.m., New York time, and ending at 4:00:00 p.m., New York time, as reported by Bloomberg through its “HP” function (set
to  weighted  average)  or,  if  the  foregoing  does  not  apply,  the  dollar  volume-weighted  average  price  of  such  security  in  the  over-the-counter  market  on  the
electronic bulletin board for such security during the period beginning at 9:30:01 a.m., New York time, and ending at 4:00:00 p.m., New York time, as reported
by Bloomberg, or, if no dollar volume-weighted average price is reported for such security by Bloomberg for such hours, the average of the highest closing bid
price and the lowest closing ask price of any of the market makers for such security as reported in the “pink sheets” by OTC Markets Group Inc. (formerly Pink
Sheets LLC). If the VWAP cannot be calculated for such security on such date on any of the foregoing bases, the VWAP of such security on such date shall be
the fair market value as mutually determined by the Company and the Holder. All such determinations shall be appropriately adjusted for any stock dividend,
stock split, stock combination, recapitalization or other similar transaction during such period.

Notwithstanding anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise pursuant

to this Section 2(c).

d)

Mechanics of Exercise.

i.

Delivery  of  Warrant  Shares  Upon  Exercise.  The  Company  shall  cause  the  Warrant  Shares  purchased  hereunder  to  be
transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository
Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either
(A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder or (B)
this Warrant is being exercised via cashless

3

exercise,  and  otherwise  by  physical  delivery  of  a  certificate,  registered  in  the  Company’s  share  register  in  the  name  of  the  Holder  or  its
designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in
the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the delivery to the Company of the Notice of Exercise, (ii)
one  (1)  Trading  Day  after  delivery  of  the  aggregate  Exercise  Price  to  the  Company  and  (iii)  the  number  of  Trading  Days  comprising  the
Standard Settlement Period after the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”). Upon
delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant
Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment
of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within the earlier of (i) two (2) Trading Days and (ii)
the number of Trading Days comprising the Standard Settlement Period following delivery of the Notice of Exercise. The Company agrees to
maintain  a  transfer  agent  that  is  a  participant  in  the  FAST  program  so  long  as  this  Warrant  remains  outstanding  and  exercisable.  As  used
herein,  “Standard  Settlement  Period”  means  the  standard  settlement  period,  expressed  in  a  number  of  Trading  Days,  on  the  Company’s
primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of Exercise.

ii.

Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request
of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant
evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other
respects be identical with this Warrant.

iii.

Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to

Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

iv.

Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to
the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of
Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its
broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock
to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage
commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant
Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell
order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and
equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or
deliver to the Holder the number of shares of Common

4

Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the
Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of
Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding
sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts
payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall
limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific
performance  and/or  injunctive  relief  with  respect  to  the  Company’s  failure  to  timely  deliver  shares  of  Common  Stock  upon  exercise  of  the
Warrant as required pursuant to the terms hereof.

v.

No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of
this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at
its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or
round up to the next whole share.

vi.

Charges,  Taxes  and  Expenses.  Issuance  of  Warrant  Shares  shall  be  made  without  charge  to  the  Holder  for  any  issue  or
transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the
Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder;
provided, however,  that  in  the  event  that  Warrant  Shares  are  to  be  issued  in  a  name  other  than  the  name  of  the  Holder,  this  Warrant  when
surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all
Transfer  Agent  fees  required  for  same-day  processing  of  any  Notice  of  Exercise  and  all  fees  to  the  Depository  Trust  Company  (or  another
established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

vii.

Closing  of  Books.  The  Company  will  not  close  its  stockholder  books  or  records  in  any  manner  which  prevents  the  timely

exercise of this Warrant, pursuant to the terms hereof.

e)

Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any
portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable
Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder’s
Affiliates (such Persons, “Attribution Parties”)), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below).  For purposes of the
foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number
of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of
shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or
any of its Affiliates or Attribution Parties and (ii)

5

exercise  or  conversion  of  the  unexercised  or  nonconverted  portion  of  any  other  securities  of  the  Company  (including,  without  limitation,  any  other  Common
Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its
Affiliates  or  Attribution  Parties.    Except  as  set  forth  in  the  preceding  sentence,  for  purposes  of  this  Section  2(e),  beneficial  ownership  shall  be  calculated  in
accordance  with  Section  13(d)  of  the  Securities  Exchange  Act  of  1934,  as  amended  (the  “Exchange  Act”)  and  the  rules  and  regulations  promulgated
thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of
the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained
in  this  Section  2(e)  applies,  the  determination  of  whether  this  Warrant  is  exercisable  (in  relation  to  other  securities  owned  by  the  Holder  together  with  any
Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice
of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and
the  Company  shall  have  no  obligation  to  verify  or  confirm  the  accuracy  of  such  determination.  In  addition,  a  determination  as  to  any  group  status  as
contemplated  above  shall  be  determined  in  accordance  with  Section  13(d)  of  the  Exchange  Act  and  the  rules  and  regulations  promulgated  thereunder.  For
purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of
Common  Stock  as  reflected  in  (A)  the  Company’s  most  recent  periodic  or  annual  report  filed  with  the  U.S.  Securities  and  Exchange  Commission  (the
“Commission”),  as  the  case  may  be,  (B)  a  more  recent  public  announcement  by  the  Company  or  (C)  a  more  recent  written  notice  by  the  Company  or  the
Transfer Agent setting forth the number of shares of Common Stock outstanding.  Upon the written or oral request of a Holder, the Company shall within one
Trading  Day  confirm  orally  and  in  writing  to  the  Holder  the  number  of  shares  of  Common  Stock  then  outstanding.    In  any  case,  the  number  of  outstanding
shares  of  Common  Stock  shall  be  determined  after  giving  effect  to  the  conversion  or  exercise  of  securities  of  the  Company,  including  this  Warrant,  by  the
Holder  or  its  Affiliates  or  Attribution  Parties  since  the  date  as  of  which  such  number  of  outstanding  shares  of  Common  Stock  was  reported.  The  “Beneficial
Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of
Common Stock issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation
provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions of
this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the 61  day after such notice is delivered
to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this
Section 2(e) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein
contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall
apply to a successor holder of this Warrant. “Affiliate” means, with respect to any Person, any other Person that directly or indirectly controls, is controlled by, or
is under common control with, such Person, it being understood for purposes of this definition that “control” of a Person means the power directly or indirectly
either  to  vote  10%  or  more  of  the  stock  having  ordinary  voting  power  for  the  election  of  directors  of  such  Person  or  direct  or  cause  the  direction  of  the
management  and  policies  of  such  Person  whether  by  contract  or  otherwise.  “Person”  means  an  individual,  a  limited  liability  company,  a  partnership,  a  joint
venture, a corporation, a trust, an unincorporated organization, any other entity or a government or any department or agency thereof.

Section 3.    Certain Adjustments.

a)

Stock  Dividends  and  Splits.  If  the  Company,  at  any  time  while  this  Warrant  is  outstanding:  (i)  pays  a  stock  dividend  or  otherwise  makes  a
distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for
avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of
Common  Stock  into  a  larger  number  of  shares,  (iii)  combines  (including  by  way  of  reverse  stock  split)  outstanding  shares  of  Common  Stock  into  a  smaller
number of shares, or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise
Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding
immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and
the  number  of  shares  issuable  upon  exercise  of  this  Warrant  shall  be  proportionately  adjusted  such  that  the  aggregate  Exercise  Price  of  this  Warrant  shall
remain  unchanged.  Any  adjustment  made  pursuant  to  this  Section  3(a)  shall  become  effective  immediately  after  the  record  date  for  the  determination  of
stockholders  entitled  to  receive  such  dividend  or  distribution  and  shall  become  effective  immediately  after  the  effective  date  in  the  case  of  a  subdivision,
combination or re-classification.

b)

Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues or sells
any  Common  Stock  Equivalents  or  rights  to  purchase  stock,  warrants,  securities  or  other  property  pro  rata  to  the  record  holders  of  any  class  of  shares  of
Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase
Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant
(without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a
record  is  taken  for  the  grant,  issuance  or  sale  of  such  Purchase  Rights,  or,  if  no  such  record  is  taken,  the  date  as  of  which  the  record  holders  of  shares  of
Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate
in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such
Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase
Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial
Ownership Limitation).

c)

Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution
of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any
distribution  of  cash,  stock  or  other  securities,  property  or  options  by  way  of  a  dividend,  spin  off,  reclassification,  corporate  rearrangement,  scheme  of
arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to
participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock
acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership
Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of
shares of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder's right to participate in
any  such  Distribution  would  result  in  the  Holder  exceeding  the  Beneficial  Ownership  Limitation,  then  the  Holder  shall  not  be  entitled  to  participate  in  such
Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a

7

result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its
right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

d)

Fundamental  Transaction.  If,  at  any  time  while  this  Warrant  is  outstanding,  (i)  the  Company,  directly  or  indirectly,  in  one  or  more  related
transactions  effects  any  merger  or  consolidation  of  the  Company  with  or  into  another  Person,  (ii)  the  Company,  directly  or  indirectly,  effects  any  sale,  lease,
license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or
indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock
are  permitted  to  sell,  tender  or  exchange  their  shares  for  other  securities,  cash  or  property  and  has  been  accepted  by  the  holders  of  50%  or  more  of  the
outstanding  Common  Stock,  (iv)  the  Company,  directly  or  indirectly,  in  one  or  more  related  transactions  effects  any  reclassification,  reorganization  or
recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for
other  securities,  cash  or  property,  or  (v)  the  Company,  directly  or  indirectly,  in  one  or  more  related  transactions  consummates  a  stock  or  share  purchase
agreement  or  other  business  combination  (including,  without  limitation,  a  reorganization,  recapitalization,  spin-off  or  scheme  of  arrangement)  with  another
Person  or  group  of  Persons  whereby  such  other  Person  or  group  acquires  more  than  50%  of  the  outstanding  shares  of  Common  Stock  (not  including  any
shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to,
such  stock  or  share  purchase  agreement  or  other  business  combination)  (each  a  “Fundamental Transaction”),  then,  upon  any  subsequent  exercise  of  this
Warrant,  the  Holder  shall  have  the  right  to  receive,  for  each  Warrant  Share  that  would  have  been  issuable  upon  such  exercise  immediately  prior  to  the
occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the
number  of  shares  of  Common  Stock  of  the  successor  or  acquiring  corporation  or  of  the  Company,  if  it  is  the  surviving  corporation,  and  any  additional
consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for
which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this
Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration
based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall
apportion  the  Exercise  Price  among  the  Alternate  Consideration  in  a  reasonable  manner  reflecting  the  relative  value  of  any  different  components  of  the
Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction,
then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental
Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to
assume  in  writing  all  of  the  obligations  of  the  Company  under  this  Warrant  and  the  other  Transaction  Documents  in  accordance  with  the  provisions  of  this
Section 3(d) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable
delay)  prior  to  such  Fundamental  Transaction  and  shall,  at  the  option  of  the  Holder,  deliver  to  the  Holder  in  exchange  for  this  Warrant  a  security  of  the
Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number
of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of
this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies
the  exercise  price  hereunder  to  such  shares  of  capital  stock  (but  taking  into  account  the  relative  value  of  the  shares  of  Common  Stock  pursuant  to  such
Fundamental Transaction and the value of such shares of

8

capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant immediately
prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of
any  such  Fundamental  Transaction,  the  Successor  Entity  shall  succeed  to,  and  be  substituted  for  (so  that  from  and  after  the  date  of  such  Fundamental
Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and
may  exercise  every  right  and  power  of  the  Company  and  shall  assume  all  of  the  obligations  of  the  Company  under  this  Warrant  and  the  other  Transaction
Documents with the same effect as if such Successor Entity had been named as the Company herein.

e)

Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For
purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of
shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

f) Notice to Holder.

i.

Adjustment  to  Exercise  Price.  Whenever  the  Exercise  Price  is  adjusted  pursuant  to  any  provision  of  this  Section  3,  the
Company  shall  promptly  deliver  to  the  Holder  by  email  a  notice  setting  forth  the  Exercise  Price  after  such  adjustment  and  any  resulting
adjustment to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

ii.

Notice to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on
the  Common  Stock,  (B)  the  Company  shall  declare  a  special  nonrecurring  cash  dividend  on  or  a  redemption  of  the  Common  Stock,  (C)  the
Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification
of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets
of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the
Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the
Company  shall  cause  to  be  delivered  by  email  to  the  Holder  at  its  last  email  address  as  it  shall  appear  upon  the  Warrant  Register  of  the
Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a
record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as
of  which  the  holders  of  the  Common  Stock  of  record  to  be  entitled  to  such  dividend,  distributions,  redemption,  rights  or  warrants  are  to  be
determined  or  (y)  the  date  on  which  such  reclassification,  consolidation,  merger,  sale,  transfer  or  share  exchange  is  expected  to  become
effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares
of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share
exchange;  provided  that  the  failure  to  deliver  such  notice  or  any  defect  therein  or  in  the  delivery  thereof  shall  not  affect  the  validity  of  the
corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material,
non-public

9

information  regarding  the  Company  or  any  of  the  Subsidiaries,  the  Company  shall  simultaneously  file  such  notice  with  the  Commission
pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date
of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4.    Transfer of Warrant.

a)

Transferability. This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part,
upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in
the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such
transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee
or  assignees,  as  applicable,  and  in  the  denomination  or  denominations  specified  in  such  instrument  of  assignment,  and  shall  issue  to  the  assignor  a  new
Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the
Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers an assignment form to the Company
assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares
without having a new Warrant issued.

b)

New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney.
Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a
new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or
exchanges shall be dated the original Issue Date of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable
pursuant thereto.

c)

Warrant Register.  The  Company  shall  register  this  Warrant,  upon  records  to  be  maintained  by  the  Company  for  that  purpose  (the  “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

Section 5.    Miscellaneous.

a)

No  Rights  as  Stockholder  Until  Exercise;  No  Settlement  in  Cash. This  Warrant  does  not  entitle  the  Holder  to  any  voting  rights,  dividends  or
other  rights  as  a  stockholder  of  the  Company  prior  to  the  exercise  hereof  as  set  forth  in  Section  2(d)(i),  except  as  expressly  set  forth  in  Section  3.  Without
limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant to Section 2(c) or to receive cash payments pursuant to Section 2(d)
(i) and Section 2(d)(iv) herein, in no event shall the Company be required to net cash settle an exercise of this Warrant.

b)

Loss,  Theft,  Destruction  or  Mutilation  of  Warrant.  The  Company  covenants  that  upon  receipt  by  the  Company  of  evidence  reasonably

satisfactory to it of the loss, theft,

10

destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security
reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant
or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of
such Warrant or stock certificate.

c)

Saturdays, Sundays, Holidays, etc. If  the  last  or  appointed  day  for  the  taking  of  any  action  or  the  expiration  of  any  right  required  or  granted

herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding Business Day.

d)

Authorized Shares.

The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The
Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the
necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be
necessary  to  assure  that  such  Warrant  Shares  may  be  issued  as  provided  herein  without  violation  of  any  applicable  law  or  regulation,  or  of  any
requirements  of  the  Trading  Market  upon  which  the  Common  Stock  may  be  listed.  The  Company  covenants  that  all  Warrant  Shares  which  may  be
issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and
payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens
and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such
issue).

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending
its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this
Warrant against impairment. Without  limiting  the  generality  of  the  foregoing,  the  Company  will  (i)  not  increase  the  par  value  of  any  Warrant  Shares
above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and
(iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction
thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the
Exercise  Price,  the  Company  shall  obtain  all  such  authorizations  or  exemptions  thereof,  or  consents  thereto,  as  may  be  necessary  from  any  public
regulatory body or bodies having jurisdiction thereof.

11

e)

Jurisdiction.  All  questions  concerning  the  construction,  validity,  enforcement  and  interpretation  of  this  Warrant  shall  be  determined  in

accordance with the provisions of the Agreement.

f)

Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder

does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

g)

Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant or the Agreement, if the
Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay
to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of
appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

h)

Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered

in accordance with the notice provisions of the Agreement.

i)

Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common
Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

j)

Remedies. The  Holder,  in  addition  to  being  entitled  to  exercise  all  rights  granted  by  law,  including  recovery  of  damages,  will  be  entitled  to
specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred
by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that
a remedy at law would be adequate.

k)

Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of
this  Warrant  are  intended  to  be  for  the  benefit  of  any  Holder  from  time  to  time  of  this  Warrant  and  shall  be  enforceable  by  the  Holder  or  holder  of  Warrant
Shares.

l)

Amendment. This  Warrant  may  be  modified  or  amended  or  the  provisions  hereof  waived  with  the  written  consent  of  the  Company  and  the

Holder.

m)

Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition
or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

n)

Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this

Warrant.

PURCHASE AND SALE OF THE PURCHASED INTEREST

Upon the terms and subject to the conditions set forth in this Agreement, on the Effective Date, Company shall sell, assign, transfer and convey to
Investor, and Investor agrees to purchase and accept the assignment, transfer and conveyance from Company, and subject to the conditions set forth in
Article  VI,  the  Purchased  Interest.  Investor’s  interest  in  the  Purchased  Interest  so  assigned  shall  vest  simultaneously  with  and  only  upon  Company’s
receipt of the full, irrevocable, non-refundable, and non-deductible upfront payment pursuant to Section 2.03(a) for such Purchased Interest.

Section 1.02 Payments to Investor.

In  consideration  of  the  Investor  paying  the  Investment  Amount  hereunder,  the  Company  shall  pay  the  Purchased  Interests  to  the  Investor  as

follows:

(a)

Payments on Account of the Purchased Interest. After cash in respect of Milestones and Royalties in respect of the Product is paid by the
Sublicensee to Company and all payments required to be made by Company under the License Agreement and Sublicense Agreement have been made to
the Licensor and Sublicensor in respect of the Product, Company shall determine the amount of Net Royalties and Net Milestone Payments and calculate
the amount of the Purchased Interest due and owing to Investor and the amount of the Retained Interest due and owing to Company. During the Payment
Term, Company shall make payments due and owing to Investor in respect of the Purchased Interest until the date on which the Investor has received
payments  in  respect  of  the  Purchased  Interests  equal  to  the  Hard  Cap.  Company  shall  make  such  payments  within  fifteen  (15)  Business  Days  of
Company’s  calculation  of  the  amount  of  the  Purchased  Interest  and  shall  provide  Investor  with  a  Quarterly  Report  setting  forth  such  amount  and  the
calculation thereof. To any extent funds paid by Sublicensee to Company are not actually deposited in an escrow account until such time as payments are
made to Investor, such funds shall be treated as escrowed and off-limits for all other purposes until Investor has been paid all amounts owed therefrom. If
any payment problems accrue due to such funds not being treated as escrowed funds, Investor shall promptly be made whole and the Parties agree to
negotiate an appropriate escrow agreement to prevent any future such irregularities. Company shall have the right, at any time and from time to time, to
make voluntary prepayments to Investor, and such payments shall be credited against the Hard Cap. This Agreement shall be in full force and effect for
the duration of the Payment Term.

(b)

Discrepancies. For avoidance of doubt, the Parties understand and agree that if a Sublicensee fails to pay any Milestones or Royalties (or
portion thereof) during the Payment Term when due under the Sublicense Agreement (each such unpaid amount, a “Discrepancy”), then Company shall
not be obligated to pay to Investor or otherwise compensate or make Investor whole with respect to any portion of such Discrepancy; provided, however,
that Company shall, at Investor’s reasonable request and upon reasonable consultation with Investor,

512258979v.3

11

enforce the terms of the Sublicense Agreement in accordance with Company’s exercise of its reasonable business judgment, and upon any recovery of a
Discrepancy,  and  the  determination  of  the  amount  of  such  Discrepancy  due  and  owing  to  Investor  in  respect  of  any  unpaid  portion  of  the  Purchased
Interest, Company shall transfer such portion of such Discrepancy in respect of the Purchased Interest to Investor as set out in Section 2.02(a).

(c)

Call Option. The Company shall have the right, but not the obligation, at any time (the “Call Option”),  exercisable  upon  ten  (10)  days’
prior written notice to Investor, to repurchase all, but not less than all, of the Purchased Interest from the Investor at a repurchase price equal to the Call
Payment. In order to exercise the Call Option, the Company shall deliver written notice to Investor of its election to so repurchase the Purchased Interest
not less than ten (10) days prior to the proposed closing date (the “Call Closing Date”); provided, however, that such notice may state that it is conditioned
upon the effectiveness of any financing transaction or one or more other events specified therein (including the occurrence of a Change of Control), in
which case such notice may be revoked by the Company (by notice to the Investor no later than five (5) days prior to the specified effective date) if such
condition is not satisfied. On the Call Closing Date, the Company shall repurchase from the Investor the Purchased Interest at a price equal to the Call
Payment, the payment of which shall be made by wire transfer of immediately available funds to the account designated by Investor.

(d)

Payment  Terms.  The  payments  to  be  made  by  Company  to  Investor  pursuant  to  this  Section  2.02  shall  be  paid  by  wire  transfer  of
immediately available funds to the account designated by Investor. In the event any amount due to Investor hereunder in respect of the Purchased Interest
(other than any Discrepancy) is not made when due, each such amount shall accrue interest from the date due at the Rate of Interest, calculated on the
basis of a 360-day, 12-month year, until payment is actually made to Investor.

(e)

Termination of Purchased Interest. Once the Investor has received (i) aggregate payments under Section 2.02(a) equal to the Hard Cap or
(ii) all of the amounts due pursuant to and in accordance with Section 2.02(c), (x) Company shall have no further obligations to the Investor with respect
to  the  Purchased  Interests,  and  Investor  will  not  be  entitled  to  any  additional  payments  in  respect  of  the  Purchased  Interests  and  (y)  each  of  the
Transaction  Documents  shall  terminate.  Immediately  upon  termination  of  this  Agreement  pursuant  to  this  Section  2.02(e),  Investor  shall  execute  and
deliver  to,  or  at  the  direction  of,  the  Company,  at  the  Company’s  sole  cost  and  expense,  all  other  releases  and  other  documents  as  the  Company  shall
reasonably request to evidence any such release.

Investment Amount 1”) within twenty (20) Business Days of the date of such notice;

ii) at any time between January 1, 2024 through December 31, 2026, Company may in its sole discretion elect to exercise its right to receive,

payment  of  up  to  Three  Million  Dollars  ($3,000,000.00)  (such  amount  so  elected  by  Company  and  paid  by  Investor  to  Company,  the
“Supplemental Discretionary Investment Amount 2”) within twenty (20) Business Days of the date of such notice;

iii)at any time between January 1, 2024 through December 31, 2026, Company may in its sole discretion elect to exercise its right to receive,

“Supplemental Discretionary Investment Amount 3”) within twenty (20) Business Days of the date of such notice; provided that the amount
of the Supplemental Discretionary Investment Amount 3 shall not exceed an amount that would cause the Total Investment Amount to
exceed Twelve Million Dollars ($12,000,000.00).

(c) Warrants.  Upon  funding  the  Initial  Investment  Amount,  Company  shall  issue  to  Investor  a  warrant  to  purchase  5,000,000  shares  of
Company  Common  Stock  in  substantially  the  form  attached  hereto  as  Exhibit  F  (the  “Closing  Warrant”).  If  Company  exercises  its  right  receive  any
Supplemental Discretionary Investment Amount in accordance with Section 2.03(b), then, upon receipt of such payment, Company shall issue to Investor
a warrant to purchase Company Common Stock in substantially the form attached hereto as Exhibit F (each, a “Supplemental Investment Warrant” and,
together with the Closing Warrant, the “Warrants”) for a number of shares equal to 1,000,000 (as adjusted in accordance with Section 3(a) of the Warrant)
for each $1,000,000 received. Any fundings which are not in even million-dollar increments shall accrue warrants pro-rata (e.g., $2,400,000/2,400,000
shares). For avoidance of doubt, the total number of shares that may become issuable under this Section 2.03(c) shall not exceed 12,000,000 (as adjusted
in accordance with Section 3(a) of the Warrant).

by Company or with Company’s prior written consent not to be unreasonably withheld or delayed.

The  confidentiality  provisions  set  forth  in  this  Section  5.04  supersede  the  provisions  of  the  Confidentiality  Agreement  in  all
respects, and all Confidential Information disclosed to Investor prior to the Effective Date shall be instead treated as Confidential Information under this
Section 5.04. Upon the Effective Date, the Confidentiality Agreement shall immediately terminate and shall have no further force and effect.

Section 1.07 Intellectual Property.

(a)

Subject in all respects to the terms and conditions of the Sublicense Agreement and License Agreement, Company shall, either directly or
by causing the Sublicensee to do so, take any actions (including taking legal action to specifically enforce the applicable terms of the License Agreement
and  the  Sublicense  Agreement)  requested  by  Investor  that  are  reasonably  necessary  to  (i)  diligently  prosecute  and  maintain  the  applicable  Intellectual
Property and the Patents in the Field in the Territory and (ii) diligently defend or assert such Intellectual Property and such Patents against infringement or
interference by any other Persons in the Field in the Territory, and against any claims of invalidity or unenforceability, in any jurisdiction in the Field

26

 
in the Territory (including, without limitation, by bringing any legal action for infringement or defending any counterclaim of invalidity or action of a
Third Party for declaratory judgment of non-infringement or non-interference). Company shall keep Investor reasonably informed of all such actions and
Investor  shall,  to  the  extent  permitted  under  the  Sublicense  Agreement  and  License  Agreement,  have  the  opportunity  to  participate  and  meaningfully
consult with Company with respect to the direction thereof. Company shall, in good faith, consider all input from Investor, and, subject to the rights of the
Licensor  under  the  License  Agreement  and  Sublicensee  under  the  Sublicense  Agreement,  if,  in  Investor’s  reasonable  judgment,  Company  does  not
exercise diligent efforts with respect to its rights under the License Agreement or Sublicense Agreement relating to the prosecution or maintenance of the
Product Specific Patents, Investor may, in its sole discretion, and only to the extent permitted under the applicable Sublicense Agreement and License
Agreement, assume control of the prosecution and maintenance of the Product Specific Patents at Investor’s sole cost and expense. Company shall not,
and shall use its commercially reasonable efforts to exercise its rights under the Sublicense Agreement and License Agreement to cause the Licensee and
Sublicensee to not, disclaim or abandon or fail to take any action necessary to prevent the disclaimer or abandonment of the applicable Patents or other
Intellectual Property where such disclaimer or abandonment would be reasonably likely to result in a Material Adverse Effect.

(b)

Company shall use commercially reasonable efforts to exercise its rights under the Sublicense Agreement and License Agreement that it

may have to prosecute all pending patent applications related to the Licensed Product as listed in Schedule 3.12(a).

(c)

Company shall directly take, or subject in all respects to the terms and conditions of the Sublicense Agreement cause Sublicensee to take,
any  and  all  actions  and  prepare,  execute,  deliver,  and  file  any  and  all  agreements,  documents  or  instruments  that  are  reasonably  necessary  in  order  to
secure and maintain all Regulatory Approvals. Company may not withdraw or abandon or fail to take any action necessary to prevent the withdrawal or
abandonment of any Regulatory Approval once obtained without the prior written consent of Investor.

(c)

amend, modify, restate, cancel, supplement, terminate or waive any provision of the License Agreement or Sublicense Agreement, or grant

provisions of the License Agreement, in each case if such action or waiver would be reasonably likely to have a material adverse effect on the amount,
timing, or duration of the payments in respect of the Purchased Interest.

(d)

create, incur, assume, or suffer to exist any Lien, or exercise any right of rescission, offset, counterclaim or defense, upon or with respect to
the  Purchased  Interest,  or  agree  to  do  or  suffer  to  exist  any  of  the  foregoing,  except  for  any  Lien  or  agreements  in  favor  of  Investor  granted  under  or

sublicensees.

Section 1.05 Successors and Assigns.

The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and, subject to this Section 7.05 and the other
provisions of this Agreement, their respective successors and permitted assigns. Company shall not be entitled to assign any of its obligations and rights
under  this  Agreement  without  the  prior  written  consent  of  Investor,  not  to  be  unreasonably  withheld,  conditioned  or  delayed,  and  any  such  purported
assignment, delegation or transfer without such consent will be void ab initio and of no effect; provided, however, such consent shall not be required in
connection  with  a  Change  of  Control  of  Company.  Neither  this  Agreement  nor  any  of  Investor’s  rights,  interests,  or  obligations  hereunder  (including

merger,  change  of  control,  or  otherwise  by  Investor  without  the  prior  written  consent  of  Company  (such  consent  not  to  be  unreasonably  withheld,
conditioned or delayed) and the consent of the Sublicensee and Licensor whose Consent is required, and any such purported assignment, delegation or
transfer without any such required consent will be void ab initio and of no effect.

Section 1.06 Indemnification; Dispute Resolution.

(a)

Company shall defend, indemnify and hold harmless Investor and its Affiliates and any of their respective directors, managers, members,
officers,  employees  and  agents  (each  a  “Investor  Indemnified  Party”)  from  and  against  any  and  all  Losses  incurred  or  suffered  by  any  Investor
Indemnified Party arising out of (i) any breach of any representation, warranty, or certification made by Company in any of the Transaction Documents or
certificates  given  by  Company  in  writing  pursuant  hereto  or  thereto,  or  (ii)  any  breach  of  or  default  under  any  covenant  or  agreement  by  Company
pursuant to any Transaction Document, including any failure by Company to satisfy any of the Excluded Liabilities and Obligations to the extent that any
such Losses are not caused by Investor and subject to indemnification by Investor hereunder; provided, however, that Company shall not be liable for the
payment to any Investor Indemnified Party for any portion of such Losses resulting from such Investor Indemnified Party’s gross negligence or willful
misconduct. Notwithstanding the foregoing, except to the extent that any Consent is insufficient to allow Investor to receive the Purchased Interest, no
Investor Indemnified Party shall be entitled to be indemnified for, or held harmless from, any Losses pursuant to this Section 7.06(a) to the extent such
Losses are based on or result from (x) the failure by any Party to obtain a required Consent, or (y) any Consent that is obtained being deficient in any way.

(b)

Investor shall defend, indemnify and hold harmless Company and its Affiliates and any of their respective directors, managers, members,
officers,  employees  and  agents  (each  a  “Company  Indemnified  Party”)  from  and  against  any  and  all  Losses  incurred  or  suffered  by  any  Company
Indemnified Party arising out of (i) any breach of any representation, warranty, or certification made by Investor in any of the Transaction Documents or
certificates given by Investor in writing pursuant hereto or thereto, (ii) any breach of or default under any covenant or agreement by Investor pursuant to
any Transaction Document, and (iii) any claims asserted by any Third Party to the extent based on action taken by Company at the express direction of
Investor pursuant to the terms of this Agreement, other than actions which Company would have been obligated to take under the Sublicense Agreement
or the License Agreement in order to avoid a breach even if Company had not been so directed by Investor; provided, however, that Investor shall not be
liable for the payment to any Company Indemnified Party for any portion of

512258979v.3

31

such Losses resulting from such Company Indemnified Party’s gross negligence or willful misconduct.

(c)

If any claim, demand, action or proceeding (including any investigation by any Governmental Authority) shall be brought or alleged by a
Third  Party  against  an  Indemnified  Party  in  respect  of  which  indemnity  is  to  be  sought  against  an  indemnifying  Party  pursuant  to  the  preceding
paragraphs  (a)  or  (b)  (a  “Third Party Claim”),  the  Indemnified  Party  shall,  promptly  after  receipt  of  notice  of  the  commencement  of  any  such  claim,
demand, action or proceeding, notify the indemnifying Party in writing of the commencement of such claim, demand, action or proceeding, enclosing a
copy  of  all  papers  served,  if  any;  provided,  that  the  omission  to  so  notify  such  indemnifying  Party  will  not  relieve  the  indemnifying  Party  from  any
liability that it may have to any Indemnified Party under the foregoing provisions of this Section 7.06 unless, and only to the extent that, such omission
results in the forfeiture of, or has a material adverse effect on the exercise or prosecution of, substantive rights or defenses by the indemnifying Party. In
case any such action is brought against an Indemnified Party and it notifies the indemnifying Party of the commencement thereof, the indemnifying Party
will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying Party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the consent of the Indemnified Party, be counsel to the
indemnifying  Party),  and  after  notice  from  the  indemnifying  Party  to  such  Indemnified  Party  of  its  election  so  to  assume  the  defense  thereof,  the
indemnifying Party will not be liable to such Indemnified Party under this Section 7.06 for any legal or other expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, an Indemnified Party shall
have the right to retain its own counsel, but the reasonable fees and expenses of such counsel shall be at the expense of such Indemnified Party unless
(i) the indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel, (ii) the indemnifying Party has assumed
the  defense  of  such  proceeding  and  has  failed  within  a  reasonable  time  to  retain  counsel  reasonably  satisfactory  to  such  Indemnified  Party  or  (iii)  the
named parties to any such proceeding (including any impleaded parties) include both the indemnifying Party and the Indemnified Party and representation
of  both  parties  by  the  same  counsel  would  be  inappropriate  due  to  actual  or  potential  conflicts  of  interests  between  them  based  on  the  advice  of  such
counsel. It is agreed that the indemnifying Party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for
the reasonable fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all such Indemnified Parties. The
indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent. No indemnifying Party shall, without the
prior written consent of the Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Party is
or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional
release of such Indemnified Party from all liability on claims that are the subject matter of such proceeding.

(d)

Claims for Breach. With the exception of breach of contract claims the indemnification afforded by this Section 7.06 shall be the sole and
exclusive remedy for any and all Losses sustained or incurred by an Indemnified Party hereto in connection with the transactions contemplated by the
Transaction Documents. With  the  exception  of  breach  of  contract  claims  the  only  legal  action  that  may  be  asserted  by  or  on  behalf  of  any  Party  with
respect to an alleged breach of this Agreement or another Transaction Document or any other matter arising out of the transactions contemplated by this
Agreement or another Transaction Document shall be an action to enforce or to recover Losses as an indemnification claim pursuant to this Section 7.06.
The Party asserting such a claim shall provide the other Party with written notice setting forth in detail the factual and legal basis for such claim, and the
Party against whom such a claim is alleged shall thereafter have 60 days within which to cure the alleged

512258979v.3

32

breach or otherwise remedy the situation. In the event the alleged breach is not cured or the situation is not otherwise remedied within such 60 day period,
the  non-breaching  Party  may  initiate  legal  action  to  enforce  its  rights  under  this  Agreement  or  another  Transaction  Document.  Without  limiting  the
generality of the foregoing, with the exception of breach of contract claims, no legal action based upon predecessor or successor liability, contribution,
tort, strict liability or any statute, regulation or ordinance may be maintained by or on behalf of any Party or any Indemnified Party with respect to any
matter that is the subject of this Section 7.06.

(e)

Losses shall be (a) calculated net of actual recoveries received by or on behalf of Indemnified Party under insurance policies, risk sharing
pools or similar arrangements (net of any actual collection costs and recoveries and deductibles) and (b) reduced by any proceeds received from third
parties, through indemnification, counterclaim or otherwise in compensation for the subject matter of an indemnification claim made hereunder. If any
proceeds,  benefits  or  recoveries  are  received  by  or  on  behalf  an  Indemnified  Party  with  respect  to  Losses  after  any  indemnifying  Party  has  made  an
indemnification payment to any Indemnified Party with respect thereto and receipt of such proceeds, benefits or recoveries prior to such payment would
have reduced the amount of such indemnification payment if received prior to such payment, then such Indemnified Party shall hold such amounts in trust
for the benefit of such indemnifying Party and, within three (3) Business Days after receipt thereof, deliver such amounts (grossed up for any applicable
withholding tax) to such indemnifying Party by wire transfer of immediately available funds as directed by such indemnifying Party.

(f)

After any final decision, judgment or award with respect to any claim for which indemnification is available under this Section 7.06 and for
which Losses have been awarded by a court of competent jurisdiction and the expiration of the time in which to appeal therefrom, the Indemnified Party
shall forward to the indemnifying Party notice of any sums due and owing by the indemnifying Party on account of any Claim for indemnification made
pursuant to this Agreement with respect to such matter, and the indemnifying Party shall pay all such amounts to the Indemnified Party within ten (10)
Business Days of receipt of such notice.

(g)

Notwithstanding anything in this Agreement to the contrary, except to the extent actually paid to a Third Party in respect of a Third Party
Claim, in no event shall (a) any Party be liable under this Section 7.06 for any indirect, consequential, special or punitive damages or loss of profits, (b)
Company and its employees, officers, directors, agents, successors or assigns, taken as a whole, be liable for any Losses in the aggregate greater than (x)
the amount of the Purchased Interest when due under this Agreement, less (y) the amount of all payments in respect of the Purchased Interest already
received by Investor, and (c) Investor or any of its employees, officers, directors, agents, successors or assigns, taken as a whole, be liable for any Losses
in the aggregate greater than the amount of the sum of the Aggregate Investment Amount and each of the Contingent Investment Amount Payments (if
any) paid by Investor to Company when due under this Agreement. For clarity, no Party hereto shall have any right to terminate this Agreement or any
other Transaction Document as a result of any breach by any other Party hereto hereof or thereof, but instead shall have the rights set forth in this Section
7.06.

(h)

The Parties shall use commercially reasonable efforts to cooperate with each other in order to resolve or mitigate any claims indemnifiable
under this Section 7.06. Each Party shall respond to any claims in substantially the same manner it would respond to such claims in the absence of the
indemnification provisions  of  this  Agreement. If  any Party intentionally  fails  to  make  such  commercially  reasonable  efforts  to mitigate or resolve any
such claim, then, notwithstanding anything else to the contrary contained herein, the other Parties shall not be required to indemnify any Person for any
portion of such indemnifiable loss that could reasonably be expected to have been avoided if such Party had made such efforts.

512258979v.3

33

(i)

Prior to bringing a legal action against the other Party, such dispute shall be separately negotiated by the Parties hereto in good faith and all
reasonable  efforts  undertaken  to  settle  amicably  such  matters  before  resorting  to  further  legal  recourse,  as  follows:  upon  the  occurrence  of  a  dispute
between the Parties, including, without limitation, any breach of this Agreement or any obligation relating thereto, the matter shall be referred first to the
officers of Company and Investor having responsibility for the subject matter of the dispute, or their designees. The officers, or their designees, as the case
may be, shall negotiate in good faith to resolve such dispute in a mutually satisfactory manner for up to thirty (30) days. If such efforts do not result in
mutually satisfactory resolution of the dispute, the matter shall be referred to the chief executive officers of Company and Investor, or their designees. The
chief executive officers, or their designees, as the case may be, shall negotiate in good faith to resolve such dispute in a mutually satisfactory manner for
up to thirty additional  (30)  days,  or  such  longer  period  of  time  to  which  the  chief executive officers may agree. In  the  event  the  dispute  has  not  been
resolved at the end of such thirty (30) day period (or such longer period as agreed to by the chief executive officers of the Parties), either Party shall be
entitled to bring an action in accordance with Section 7.06(a) and (b), above.

Section 1.07 Independent Nature of Relationship.

The relationship between Company, on the one hand, and Investor, on the other hand, is solely that of assignor and assignee, and neither Investor,

on the one hand, nor Company, on the other hand, has any fiduciary or other special relationship with the other or any of their respective Affiliates.

Section 1.08 Tax.

(a)

The  Parties  (i)  agree  that  for  U.S.  federal  and  applicable  state  and  local  income  Tax  purposes,  the  transactions  contemplated  by  this
Agreement  are  intended  to  constitute  a  debt  instrument  that  is  subject  to  U.S.  Treasury  Regulations  under  Section  1.1275-4(b)  governing  contingent
payment  debt  instruments  and  (ii)  agree  that  the  rights  in  respect  of  the  Total  Investment  Amount  constitute  a  debt  instrument  for  U.S.  federal  and
applicable  state  and  local  income  tax  purposes.  The  Parties  agree  not  to  take  and  to  not  cause  or  permit  their  Affiliates  to  take,  any  position  that  is
inconsistent  with  the  provisions  of  this  Section  7.08  on  any  U.S.  federal,  state  or  local  income  Tax  return  or  for  any  other  U.S.  federal,  state  or  local
income  Tax  purpose,  unless  the  Party  that  contemplates  taking  such  an  inconsistent  position  has  been  advised  by  national  recognized  counsel  or
accounting firm in writing that it is more likely than not that the inconsistent position is required by applicable Law or unless required by the good faith
resolution of a Tax audit or other Tax proceeding.

POLICY ON RECOVERY OF ERRONEOUSLY AWARDED COMPENSATION

DARÉ BIOSCIENCE, INC.

1
November 17, 2023

1.

Overview

The  Board  believes  that  it  is  in  the  best  interests  of  the  Company  and  its  stockholders  to  adopt  this  Policy  to  provide  for  the  recovery  of  certain  Incentive-Based
Compensation in the event of an Accounting Restatement. This Policy is designed to comply with, and shall be interpreted to be consistent with, Section 10D of the
Exchange Act, the regulations and rules promulgated by the SEC thereunder, including, without limitation, Rule 10D-1 promulgated under the Exchange Act (“Rule 10D-
1”), and the applicable rules, regulations and listing standards of the Exchange (collectively, and as the same may be in effect from time to time, the “Applicable Rules”).
Unless otherwise defined in this Policy, capitalized terms used in this Policy have the meanings given to them in Section 2.

2.

Definitions

(a) “Accounting Restatement”  means  an  accounting  restatement  of  the  Company’s  financial  statements  due  to  the  Company’s  material  noncompliance  with  any
financial  reporting  requirement  under  U.S.  securities  laws,  including  any  required  accounting  restatement  to  correct  an  error  in  previously  issued  financial
statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current
period or left uncorrected in the current period.

(b) “Board” means the Board of Directors of the Company, as constituted from time to time.

(c) “Clawback Eligible Incentive-Based Compensation” means, in connection with an Accounting Restatement and with respect to each individual who served as a
Senior Executive at any time during the applicable performance period for any Incentive-Based Compensation (whether or not such Senior Executive is serving
at the time the Erroneously Awarded Compensation is required to be recouped by the Company), all Incentive-Based Compensation Received by such Senior
Executive (i) on or after the Effective Date, (ii) after beginning service as a Senior Executive, (iii) while the Company has a class of securities listed on a national
securities exchange, and (iv) during the applicable Look-Back Period.

(d) “Committee” means the Compensation Committee of the Board or such other committee or subcommittee of the Board, if any, duly appointed to administer this
Policy and having such powers in each instance as shall be specified by the Board and as specified in Section 3 of this Policy. The Board may also serve as the
Committee.

(e) “Company” means Daré Bioscience, Inc., a Delaware corporation.

(f)

“Effective Date” means October 2, 2023.

(g) “Erroneously  Awarded  Compensation”  means,  with  respect  to  each  Senior  Executive  in  connection  with  an  Accounting  Restatement,  the  amount  of  the
Clawback  Eligible  Incentive-Based  Compensation  that  exceeds  the  amount  of  the  Incentive-Based  Compensation  that  would  have  been  Received  had  the
amount of such Incentive-Based Compensation been calculated based on the restated amounts, as determined by the Committee, calculated by the Committee
without  regard  to  any  taxes  paid.  With  respect  to  Incentive-Based  Compensation  based  on  (or  derived  from)  TSR  or  stock  price,  where  the  amount  of
Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in the applicable Accounting Restatement, the
Committee shall determine the amount of Erroneously Awarded Compensation based on a reasonable estimate of the effect of the Accounting Restatement on
the TSR or stock price upon which the Incentive-Based Compensation was Received.

(h) “Exchange” means The Nasdaq Stock Market.

(i)

“Exchange Act” means the Securities Exchange Act of 1934, as amended.

Exhibit 97

(j)

“Financial  Reporting  Measure”  means  any  measure  that  is  determined  and  presented  in  accordance  with  the  accounting  principles  used  in  preparing  the
Company’s  financial  statements,  and  any  measure  that  is  derived  wholly  or  in  part  from  such  measure,  including  but  not  limited  to,  “non-GAAP  financial
measures” for purposes of Exchange Act Regulation G and Item 10 of Regulation S-K, as well as other measures, metrics and ratios that are not non-GAAP
measures, like same store sales. Financial Reporting Measures include but are not limited to the following (and any measures derived from the following): stock
price; TSR; revenues; net income; operating income; profitability of one or more reportable segments; financial ratios (e.g., accounts receivable turnover and
inventory  turnover  rates);  earnings  before  interest,  taxes,  depreciation  and  amortization;  funds  from  operations  and  adjusted  funds  from  operations;  liquidity

per share); sales per square foot or same store sales, where sales is subject to an Accounting Restatement; revenue per user, or average revenue per user,
where  revenue  is  subject  to  an  Accounting  Restatement;  cost  per  employee,  where  cost  is  subject  to  an  Accounting  Restatement;  any  of  such  financial
reporting measures relative to a peer group, where the Company’s financial reporting measure is subject to an Accounting Restatement; and tax basis income.
A Financial Reporting Measure need not be presented within the Company’s financial statements or included in a report or other document filed with the SEC.

(k) “Incentive-Based Compensation”  means  any  compensation  granted,  earned  or  vested  based  wholly  or  in  part  upon  the  attainment  of  a  Financial  Reporting

an incentive plan that were granted or vested based wholly or in part on satisfying a Financial Reporting Measure performance goal.

(l)

“Look-Back  Period”  means,  with  respect  to  an  Accounting  Restatement,  the  three  completed  fiscal  years  of  the  Company  immediately  preceding  the
Restatement Date and any transition period (that results from a change in the Company’s fiscal year) within or immediately following those three completed
fiscal years (except that a transition period that comprises a period of at least nine months shall count as a completed fiscal year).

time to time.

in the Company’s fiscal period during which the applicable Financial Reporting Measure specified in the Incentive-Based Compensation award is attained, even
if the payment or grant of such Incentive-Based Compensation occurs after the end of that period. If an equity award vests only upon satisfaction of a Financial
Reporting Measure performance condition, the award shall be deemed Received in the fiscal period when it vests. Ministerial acts or other conditions necessary
to  effect  issuance  or  payment,  such  as  calculating  the  amount  earned  or  obtaining  Board  approval  of  payment,  do  not  affect  the  determination  of  the  date
Received.

(o) “Restatement Date” means the earlier to occur of (i) the date the Board, a committee of the Board, or the officer or officers of the Company authorized to take
such  action  if  Board  action  is  not  required,  concludes,  or  reasonably  should  have  concluded,  that  the  Company  is  required  to  prepare  an  Accounting
Restatement or (ii) the date a court, regulator or other legally authorized

Exhibit 97

body directs the Company to prepare an Accounting Restatement, in each case regardless of if or when the restated financial statements are filed.

(p) “SEC” means the U.S. Securities and Exchange Commission.

(q) “Senior  Executives”  means  any  person  who  was  the  Company’s  president,  principal  financial  officer,  principal  accounting  officer  (or  if  there  is  no  such
accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as sales, administration,
or finance), any other officer who performed a policy-making function, or any other person who performed similar policy-making functions for the Company and
any other “key employees” who were designated as “Senior Executives” by the Committee. Executive officers of the Company’s parents or subsidiaries may be
deemed Senior Executives if they perform policy-making functions for the Company. For purposes of this definition, policy-making function is not intended to
include policy-making functions that are not significant. All executive officers of the Company identified by the Board pursuant to Item 401(b) of Regulation S-K
shall be deemed Senior Executives.

(r)

“TSR” means total stockholder return.

3.

Administration of Policy

The Policy shall be administrated by the Committee. All questions of interpretation or application of this Policy shall be determined by the Committee.

(a)
All Committee decisions shall be final and binding upon all persons and shall be afforded the maximum deference permitted under applicable law. The
Committee is authorized to make all determinations necessary, appropriate or advisable for the administration of this Policy and to use any of the Company’s
resources it deems appropriate to recoup Erroneously Awarded Compensation.

Determinations of financial and/or accounting irregularities for purposes of this Policy shall be made by the Committee independently of, and the

(b)
Committee shall not be bound by, determinations by management or by any other committee of the Board.

In the administration of this Policy, the Committee is authorized and directed to consult with the full Board or such other committees of the Board as

(c)
may be necessary or appropriate as to matters within the scope of such other committee’s responsibility and authority. Subject to any limitation under applicable
law, the Committee may authorize and empower any officer or employee of the Company to take any and all actions necessary or appropriate to carry out the
purpose and intent of this Policy (other than with respect to any recovery under this Policy involving such officer or employee).

4.

Accounting Restatements; Recoupment

If the Company is required to prepare an Accounting Restatement, the Company shall determine, in accordance with this Policy and the Applicable

(a)
Rules, the amount of any Erroneously Awarded Compensation for each Senior Executive in connection with such Accounting Restatement, irrespective of any
fault, misconduct or responsibility of any Senior Executive for the Accounting Restatement, and thereafter the Company shall reasonably promptly recover such
amount of Erroneously Awarded Compensation. In connection with the foregoing, the Committee, which may act in conjunction with the Company’s Audit
Committee, shall take all such actions required by this Policy and the Applicable Rules.

(b)
If there was Erroneously Awarded Compensation, the Committee shall determine, in its sole discretion, the timing and method(s) for promptly recouping
the same, which methods may include, without limitation, one or more of the following: (i) requiring reimbursement of any Erroneously Awarded Compensation;
(ii) requiring reimbursement of any equity based compensation awarded; (iii) cancelling outstanding cash or equity-based awards, whether vested or unvested
or paid or unpaid; (iv) cancelling or offsetting against any compensation otherwise owed by the Company to the Senior Executive, including any future cash or
equity-based awards; (v) requiring the forfeiture of deferred compensation, subject to compliance with Section 409A of

Exhibit 97

the Internal Revenue Code and the regulations promulgated thereunder; (vi) seeking recovery of any gain realized on the vesting, exercise, settlement, sale,
transfer, or other disposition of any equity-based awards; and (viii) pursuing any other reasonable remedies. Subject to compliance with applicable law, the
Committee may effect recoupment under this Policy from any amount otherwise payable to a Senior Executive, including amounts payable to such individual
under any otherwise applicable Company plan or program, including base salary, bonuses or commissions and compensation previously deferred by the Senior
Executive.

To the extent that the Committee determines to recoup Erroneously Awarded Compensation from a Senior Executive by requiring the repayment of

(c)
such Erroneously Awarded Compensation to the Company, and such Senior Executive fails to repay all Erroneously Awarded Compensation to the Company
when due, the Company may take all actions reasonable and appropriate to recover such Erroneously Awarded Compensation from the applicable Senior
Executive. The applicable Senior Executive shall be required to reimburse the Company for any and all expenses reasonably incurred (including legal fees) by
the Company in recovering such Erroneously Awarded Compensation in accordance with the immediately preceding sentence.

In the event of an Accounting Restatement, except to the extent permitted by the Applicable Rules, the Committee will generally treat all Senior

(d)
Executives (including former employees) the same with respect to any actions seeking to recoup Erroneously Awarded Compensation.

5.

Impracticability

Notwithstanding  anything  to  the  contrary  herein,  the  Company  shall  not  be  required  to  recoup  Erroneously  Awarded  Compensation  under  this  Policy  if  the
Compensation  Committee  of  the  Board,  or  in  the  absence  of  such  a  committee,  a  majority  of  the  independent  directors  serving  on  the  Board,  has  determined  that
recovery would be impracticable in accordance with the Applicable Rules and subject to the procedural and disclosure requirements in the Applicable Rules.

6.

Other Recoupment Rights

The Board intends that this Policy shall be applied to the fullest extent of the law. Any right of recoupment under this Policy is in addition to, and not in lieu of,
any other remedies or rights of recoupment that may be available to the Company under applicable law (including, without limitation, Section 304 of the U.S. Sarbanes-
Oxley Act of 2002, as amended, or Section 954 of the U.S. Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, as amended), pursuant to the terms
of any other policy of the Company, pursuant to the terms of any employment agreement, equity award agreement, severance or other agreement, and any other legal
remedies available to the Company. Nothing herein, and no recoupment or recovery as contemplated by this Policy, shall (i) limit any claims, damages or other legal
remedies the Company or any of its affiliates may have against a Senior Executive arising out of or resulting from any actions or omissions by the Senior Executive or
(ii) limit the Company’s ability to seek recovery, in appropriate circumstances (including circumstances beyond the scope of this Policy) as permitted by applicable law,
of any amounts from any employee, whether or not the employee is a Senior Executive.

7.

No Indemnification or Company-Paid Insurance

Notwithstanding the terms of any indemnification or insurance policy or any contractual arrangement with any Senior Executive that may be interpreted to the
contrary: (a) the Company shall not indemnify any Senior Executive against (i) the loss of any Erroneously Awarded Compensation that is recouped, repaid, returned or
recovered pursuant to the terms of this Policy; or (ii) any claims relating to the Company’s enforcement of its rights under this Policy; and (b) the Company is prohibited
from paying or reimbursing a Senior Executive for the cost of or premiums of any third-party insurance purchased to fund any potential obligations of a Senior Executive
under this Policy. Further, the Company shall not enter into any agreement that exempts any Incentive-Based Compensation from the application of this Policy or that
waives the Company’s right to recoup any Erroneously Awarded Compensation, and this Policy shall supersede any such agreement (whether entered into before, on
or after the Effective Date).

Exhibit 97

8.

Committee Indemnification

No members of the Committee, nor any other members of the Board who assist in the administration of this Policy, nor any officer of employee of the Company
authorized and empowered by the Committee who assists in the administration of this Policy shall be personally liable for any action, determination or interpretation
made with respect to this Policy, and each of the foregoing shall be fully indemnified by the Company to the fullest extent under applicable law and Company policy with
respect to any such action, determination or interpretation. The foregoing sentence shall not limit any other rights to indemnification of the members of the Board or any
officer of employee of the Company under applicable law, Company policy or contractual arrangement.

9.

Retroactive Application

This Policy applies to any Incentive-Based Compensation that is Received by a Senior Executive on or after the Effective Date, even if such Incentive-Based
Compensation was approved, awarded, granted or paid to such Senior Executive prior to the Effective Date. Without limiting the generality of Section 4, and subject to
applicable  law,  the  Committee  may  recoup  Erroneously  Awarded  Compensation  under  this  Policy  from  any  amount  of  compensation  approved,  awarded,  granted,
payable or paid to the Senior Executive prior to, on or after the Effective Date.

10.

Notice to Senior Executives

The Company shall provide notice and seek written agreement to this Policy from each Senior Executive in form attached hereto; provided, that the failure to
