ITEM 1.     BUSINESS

Overview

PART I

We are a commercial-stage medical device company that designs, manufactures and sells real-time image-guided, minimally invasive catheter-based
systems that are used by physicians to treat patients with peripheral artery disease, or PAD. Patients with PAD have a build-up of plaque in the arteries that
supply blood to areas away from the heart, particularly the pelvis and legs. Our mission is to significantly improve the treatment of vascular disease through
the introduction of products based on our Lumivascular platform, the only intravascular real-time image-guided system available in this market.

We  design,  manufacture,  and  sell  a  suite  of  products  in  the  United  States  and  select  international  markets.  We  are  located  in  Redwood  City,
California.  Our  current  proprietary  image-guided  Lumivascular  platform  includes  the  Lightbox  real-time  imaging  console,  the  Ocelot  family  of  catheters,
which are image-guided catheters designed to allow physicians to penetrate a total blockage in an artery, known as a chronic total occlusion, or CTO, and the
Pantheris  family  of  catheters,  our  image-guided  atherectomy  family  of  catheters  designed  to  allow  physicians  to  precisely  remove  arterial  plaque  in  PAD
patients.

We received CE Marking for our original Ocelot product in September 2011 and received from the U.S. Food and Drug Administration, or FDA,
510(k)  clearance  in  November  2012.  We  received  510(k)  clearance  from  the  FDA  for  commercialization  of  Pantheris  in  October  2015.  We  received  an
additional 510(k) clearance for an enhanced version of Pantheris in March 2016 and commenced sales of Pantheris in the United States and select European
countries promptly thereafter. In May 2018, we received 510(k) clearance from the FDA for our current next-generation version of Pantheris. In April 2019,
we  received  510(k)  clearance  from  the  FDA  for  our  Pantheris  SV,  a  version  of  Pantheris  targeting  smaller  vessels,  and  commenced  sales  in  July  2019.  In
September 2020, we received 510(k) clearance of Tigereye, a next-generation CTO crossing system utilizing Avinger’s proprietary image-guided technology
platform.  Tigereye  is  a  product  line  extension  of  Avinger’s  Ocelot  family  of  image-guided  CTO  crossing  catheters.  In  January  2022,  we  received  510(k)
clearance  from  the  FDA  for  our  Lightbox  3  imaging  console,  a  version  of  our  Lightbox  presenting  significant  reductions  in  size,  weight  and  cost  in
comparison to the incumbent version.

Current treatments for PAD, including bypass surgery, can be costly and may result in complications, high levels of post-surgery pain, and lengthy
hospital stays and recovery times. Minimally invasive, or endovascular, treatments for PAD include stenting, angioplasty, and atherectomy, which is the use of
a catheter-based device for the removal of plaque. These treatments all have limitations in their safety or efficacy profiles and frequently result in recurrence
of the disease, also known as restenosis. We believe one of the main contributing factors to high restenosis rates for PAD patients treated with endovascular
technologies  is  the  amount  of  vascular  injury  that  occurs  during  an  intervention.  Specifically,  these  treatments  often  disrupt  the  membrane  between  the
outermost layers of the artery, which is referred to as the external elastic lamina, or EEL.

We  believe  our  Lumivascular  platform  is  the  only  technology  that  offers  real-time  visualization  of  the  inside  of  the  artery  during  PAD  treatment
through  the  use  of  optical  coherence  tomography,  or  OCT,  a  high  resolution,  light-based,  radiation-free  imaging  technology.  Our  Lumivascular  platform
provides physicians with real-time OCT images from the inside of an artery, and we believe Ocelot and Pantheris are the first and only products in the market
to offer intravascular visualization during CTO crossing and atherectomy, respectively. We believe this approach will significantly improve patient outcomes
by providing physicians with a clearer picture of the artery using radiation-free image guidance during treatment, enabling them to better differentiate between
plaque and healthy arterial structures. Our Lumivascular platform is designed to improve patient safety by enabling physicians to direct treatment towards the
plaque, while avoiding damage to healthy portions of the artery.

During  the  first  quarter  of  2015,  we  completed  enrollment  of  patients  in  VISION,  a  clinical  trial  designed  to  support  our  August  2015
510(k)  submission  to  the  FDA  for  our  Pantheris  atherectomy  device.  VISION  was  designed  to  evaluate  the  safety  and  efficacy  of  Pantheris  to  perform
atherectomy  using  intravascular  imaging  and  successfully  achieved  all  primary  and  secondary  safety  and  efficacy  endpoints.  We  believe  the  data  from
VISION allows us to demonstrate that avoiding damage to healthy arterial structures, and in particular disruption of the external elastic lamina, which is the
membrane  between  the  outermost  layers  of  the  artery,  reduces  the  likelihood  of  restenosis,  or  re-narrowing,  of  the  diseased  artery.  Although  the  original
VISION study protocol was not designed to follow patients beyond six months, we worked with 18 of the VISION sites to re-solicit consent from previous
clinical trial patients in order for them to evaluate patient outcomes through 12 and 24 months following initial treatment. Data collection for the remaining
patients from participating sites was completed in May 2017, and we released the final 12- and 24-month results for a total of 89 patients in July 2017.

During the fourth quarter of 2017, we began enrolling patients in INSIGHT, a clinical trial designed to support a submission to the FDA to expand
the indication for our Pantheris atherectomy device to include in-stent restenosis. Patient enrollment began in October 2017 and was completed in July 2021.
Patient outcomes were evaluated at thirty days, six months and one year following treatment. In November 2021, we received 510(k) clearance from the FDA
for a new clinical indication for treating in-stent restenosis with Pantheris using the data collected and analyzed from INSIGHT. We expect this will expand
our addressable market for Pantheris to include a high-incidence disease state for which there are few available indicated treatment options.

We  focus  our  direct  sales  force,  marketing  efforts  and  promotional  activities  on  interventional  cardiologists,  vascular  surgeons  and  interventional
radiologists. We also work on developing strong relationships with physicians and hospitals that we have identified as key opinion leaders. Although our sales
and marketing efforts are directed at these physicians since they are the primary users of our technology, we consider the hospitals and medical centers where
the procedure is performed to be our customers, as they typically are responsible for purchasing our products. We are designing additional future products to
be compatible with our Lumivascular platform, which we expect to enhance the value proposition for hospitals to invest in our technology. Pantheris qualifies
for existing reimbursement codes currently utilized by other atherectomy products, further facilitating adoption of our products.

We have assembled a team with extensive medical device development and commercialization experience in both start-up and large, multi-national
medical device companies. We assemble all of our products at our manufacturing facility but certain critical processes, such as coating and sterilization, are
performed by outside vendors. We expect our current manufacturing facility in California, will be sufficient through at least 2022. We generated revenues of
$9.1 million in 2019, $8.8 million in 2020 and $10.1 million in 2021. The decline revenue in 2020 was primarily due to the adverse effects of COVID-19 on
our customers as hospitals deferred elective procedures.

Our Products

Our  current  products  include  our  Lightbox  imaging  console  and  our  various  catheters  used  in  PAD  treatment.  All  of  our  revenues  are  currently
derived from sales of our various PAD catheters and Lightbox imaging console and related services in the United States and select international markets. Each
of our current products is, and our future products will be, designed to address significant unmet clinical needs in the treatment of vascular disease.

The Lightbox 3 incorporates advanced features, including an advanced solid-state laser for enhanced high-definition OCT imaging, a more powerful
computing platform, and a redesigned software system with a highly intuitive user interface that emphasizes efficiency and ease-of-use, intended to
deliver advancements in imaging and portability. We initiated a limited launch of Lightbox 3 in the United States in the first quarter of 2022 and
expect to expand to full commercial availability shortly thereafter.

The Pantheris SV system is intended to remove plaque (atherectomy) from partially occluded vessels in the peripheral vasculature with a reference
diameter of 2.0 mm to 4.0 mm, using OCT-assisted orientation and imaging. The system is an adjunct to fluoroscopy by providing images of vessel
lumen, wall structures and vessel morphologies. The Pantheris SV system is contraindicated for use in the iliac, coronary, cerebral, renal or carotid
vasculature.

The  Pantheris  system  is  intended  to  remove  plaque  (atherectomy)  from  partially  occluded  vessels  in  the  peripheral  vasculature  with  a  reference
diameter of 3.0 mm to 7.0 mm, using OCT-assisted orientation and imaging. The system is an adjunct to fluoroscopy by providing images of vessel
lumen,  wall  structures  and  vessel  morphologies.  The  Pantheris  system  is  contraindicated  for  use  in  the  iliac,  coronary,  cerebral,  renal  or  carotid
vasculature.

The  Ocelot  system  is  intended  to  facilitate  the  intra-luminal  placement  of  conventional  guidewires  beyond  stenotic  lesions  including  subtotal  and
chronic  total  occlusions  in  the  peripheral  vasculature  prior  to  further  percutaneous  interventions  using  OCT-assisted  orientation  and  imaging.  The
system is an adjunct to fluoroscopy and provides images of vessel lumen, plaques and wall structures. The Ocelot system is contraindicated for use in
the iliac, coronary, cerebral, renal and carotid vasculature.

Lumivascular Platform Overview

Our  Lumivascular  platform  integrates  OCT  (optical  coherence  tomography)  visualization  with  interventional  catheters  and  is  the  industry’s  only
system  that  provides  real-time  intravascular  imaging  simultaneously  with  treatment  in  PAD  procedures.  Our  Lumivascular  platform  consists  of  a  capital
component, Lightbox, and a variety of disposable catheter products, including the Ocelot and Pantheris family of catheters.

Lightbox

Lightbox, including its subsequent versions, is our proprietary video imaging console, which enables the use of Lumivascular catheters during PAD
procedures. The console contains an optical transceiver that transmits light into the artery through an optical fiber and displays a cross-sectional image of the
vessel to the physician on a high-definition monitor during the procedure.

Lightbox displays a cross-sectional view of the vessel, which provides physicians with detailed information about the orientation of the catheter and
the surrounding artery and plaque. Layered structures represent relatively healthy portions of the artery and non-layered structures represent the plaque that is
blocking blood flow in the artery. Navigational markers allow the physician to orient the catheter toward the treatment area, helping to avoid damage to the
healthy arterial structures during a procedure. Lightbox received FDA 510(k) clearance in November 2012 and CE Marking in Europe in September 2011.

In January 2022, we received 510(k) clearance from the FDA for our next generation Lightbox 3 imaging console, the Lightbox 3, a version of our
Lightbox  that  delivers  important  advancements  in  imaging,  portability  and  capability  in  comparison  to  the  incumbent  version.  Lightbox  3  incorporates
advanced features, including an advanced solid-state laser for enhanced high-definition OCT imaging, a more powerful computing platform, and a redesigned
software system with a highly intuitive user interface that emphasizes efficiency and ease-of-use. We initiated a limited launch of Lightbox 3 in the United
States in the first quarter of 2022 and expect to expand to full commercial availability shortly thereafter.

Pantheris

We  believe  Pantheris  is  the  first  atherectomy  catheter  to  incorporate  real-time  OCT  intravascular  video  imaging.  Pantheris  may  be  used  alone  or
following a CTO crossing procedure using Ocelot or other products. Pantheris is a single-use product and provides physicians with the ability to see a cross-
sectional view of the peripheral artery to guide the removal of blockages throughout the procedure. The Pantheris device restores blood flow by shaving strips
of plaque using a high-speed directional cutting mechanism that enables physicians to specifically target the portion of the artery where the plaque resides
while minimizing disruption to healthy arterial structures. The excised plaque is deposited, collected and contained into the nosecone of the Pantheris device
and removed from the artery within the device.

In  October  2015,  we  received  510(k)  clearance  from  the  FDA  for  commercialization  of  Pantheris.  We  made  modifications  to  Pantheris  after  the
completion of the VISION trial and commenced sales in the United States and select international markets following receipt of FDA approval for this initial
version  of  Pantheris  in  March  2016.  We  first  received  CE  Marking  for  Pantheris  in  June  2015.  We  received  CE  Marking  in  December  2017  and  510(k)
clearance in May 2018 for a next-generation version of Pantheris, which includes new features and design improvements to the handle, shaft, balloon and
nosecone  of  the  device.  The  next-generation  Pantheris  atherectomy  device  is  currently  available  for  commercial  sale  in  the  United  States  and  select
international markets. All previous versions of Pantheris have been discontinued.

We  also  developed  a  line  extension  of  our  Pantheris  image-guided  atherectomy  platform,  Pantheris  SV  (Small  Vessel),  a  lower  profile  version  of
Pantheris. The Pantheris SV has a smaller diameter and longer length and is designed for use in smaller vessels 2.0 to 4.0 millimeters in diameter. We received
CE Marking in October 2018 and 510(k) clearance in April 2019 for this product and commenced sales in the United States in July 2019.

Ocelot and Tigereye

Ocelot is the first CTO crossing catheter to incorporate real-time OCT video imaging, which allows physicians to see the inside of a peripheral artery
during  a  CTO  crossing  procedure.  Physicians  have  traditionally  relied  solely  on  fluoroscopy  and  tactile  feedback  to  guide  catheters  through  complicated
blockages.  Ocelot  allows  physicians  to  accurately  navigate  through  CTOs  by  utilizing  the  OCT  images  to  precisely  guide  the  device  through  the  arterial
blockage,  while  minimizing  disruption  to  the  healthy  arterial  structures.  A  successful  CTO  crossing  and  placement  of  a  guidewire  allows  the  physician  to
subsequently treat the vessel with a minimally invasive therapeutic device. We received CE Marking for Ocelot in September 2011 and received FDA 510(k)
clearance in November 2012.

We also offer Ocelot PIXL, a lower profile CTO crossing device for below-the-knee arteries and Ocelot MVRX, which offers a different tip design
for peripheral arteries above-the-knee. We received CE Marking for Ocelot PIXL in October 2012 and received FDA 510(k) clearance in December 2012. We
received FDA 510(k) clearance for Ocelot MVRX in December 2012.

Tigereye  is  a  product  line  extension  of  our  Ocelot  family  of  image-guided  CTO  crossing  catheters.  Its  design  elements  include  an  upgrade  of  the
image  capture  rate  to  provide  high  definition,  real-time  intravascular  video  imaging  similar  to  the  Pantheris  image-guided  atherectomy  system  and  a  user-
controlled deflectable tip designed to assist in steerability across the blockage. We received CE Marking for Tigereye in December 2019 and received FDA
510(k)  clearance  in  September  2020.  The  product  became  available  in  the  fourth  quarter  of  2020  for  first  cases  in  the  U.S  with  a  full  commercial  launch
following shortly thereafter in the first quarter of 2021.

Other Products

Our first-generation CTO crossing catheters, Wildcat and Kittycat 2, employ a proprietary design that uses a rotational spinning technique, allowing
the physician to switch between passive and active modes when navigating across a CTO. Once across the CTO, Wildcat and Kittycat 2 allow for placement
of a guidewire and removal of the catheter while leaving the wire in place for additional therapies. Both products require the use of fluoroscopy solely rather
than our Lumivascular (OCT-guided) platform for imaging. Wildcat was our first commercial product and has both FDA 510(k) clearance in the United States
and CE Marking in Europe for crossing peripheral artery CTOs. Kittycat 2 has FDA 510(k) clearance in the United States and CE Marking in Europe for the
treatment  of  peripheral  artery  CTOs.  We  are  not  expecting  to  sell  these  products  in  the  future,  as  we  are  focusing  on  the  promotion  of  our  Lumivascular
platform products.

Clinical Development

We have conducted several clinical trials to evaluate the safety and efficacy of our products in both pre-market and post-market assessments. We
received FDA clearance for Ocelot CTO crossing in 2012 and for Pantheris in October 2015 for atherectomy in peripheral arteries and in November 2021 for
the addition of treatment of in-stent restenosis following completion of clinical trials of the devices.

CONNECT II (Ocelot)

Our clinical trial for Ocelot, known as CONNECT II, was a prospective, multi-center, non-randomized trial that evaluated the safety and efficacy of
Ocelot in crossing CTOs in arteries of the upper leg using OCT intravascular imaging. The CONNECT II trial enrolled 100 patients with CTOs at 13 centers
in the United States and 2 centers in Europe. Patients were followed for 30 days post-procedure and an independent group of physicians verified the results to
confirm the primary efficacy and safety endpoints. Results from the CONNECT II trial demonstrated that Ocelot surpassed its primary efficacy endpoint by
successfully crossing the CTO in 97% of the cases following unsuccessful attempts to cross with standard guidewire techniques. Ocelot achieved these rates
with 98% freedom from MAEs.

VISION (Pantheris)

VISION was our pivotal, non-randomized, prospective, single-arm trial to evaluate the safety and effectiveness of Pantheris across 20 sites within the
United States and Europe. The objective of the clinical trial was to demonstrate that Pantheris can be used to effectively remove plaque from diseased lower
extremity arteries while using on-board visualization as an adjunct to fluoroscopy. Two groups of patients were treated in VISION: (1) optional roll-ins, which
are typically the first two procedures at a site, and (2) the primary cohort, which are the analyzable group of patients. The data for these two groups were
reported separately in our 510(k) submission to the FDA. Based on final enrollment, the primary cohort included 130 patients. In March 2015, we completed
enrollment  of  patients  in  the  VISION  clinical  trial  and  we  submitted  for  510(k)  clearance  from  the  FDA  in  August  2015.  In  October  2015,  we  received
510(k)  clearance  from  the  FDA  for  commercialization  of  Pantheris.  We  made  modifications  to  Pantheris  subsequent  to  the  completion  of  VISION  and
received 510(k) clearance on the enhanced version of Pantheris in March 2016 and received 501(k) clearance in May 2018 for a next-generation version of
Pantheris, which includes new features and design improvements to the handle, shaft, balloon, and nose cone of the device as well as 510(k) clearance in April
2019 for Pantheris SV, a lower profile Pantheris.

VISION’s primary efficacy endpoint required that at least 87% of lesions treated by physicians using Pantheris have a residual stenosis of less than
50%,  as  verified  by  an  independent  core  laboratory.  The  primary  safety  endpoint  required  that  less  than  43%  of  patients  experience  an  MAE  through  six-
month follow-up as adjudicated by an independent Clinical Events Committee, or CEC. MAEs as defined in VISION included cardiovascular-related death,
unplanned major index limb amputation, clinically driven target lesion revascularization, or TLR, heart attack, clinically significant perforation, dissection,
embolus,  and  pseudoaneurysm.  Results  from  the  VISION  trial  demonstrated  that  Pantheris  surpassed  its  primary  efficacy  and  safety  endpoints;  residual
restenosis of less than 50% was achieved in 96.3% of lesions treated in the primary cohort, while MAEs were experienced in 16.6% of patients.

Although  not  mandated  by  the  FDA  to  support  the  market  clearance  of  Pantheris,  the  protocol  for  the  VISION  trial  allowed  for  routine
histopathological analysis of the tissue extracted by Pantheris to be conducted. This process allowed us to determine the amount of adventitia present in the
tissue, which in turn indicated the extent to which the external elastic lamina had been disrupted during Pantheris procedures. We completed histopathological
analysis on tissue from 129 patients in the primary cohort, representing 162 lesions and determined that the average percent area of adventitia was only 1.0%
of the total excised tissue. We believe the low level of EEL disruption will correlate to lower restenosis rates and improved long-term outcomes for patients
treated with Pantheris. We published the results of the histopathological analysis in conjunction with the primary safety and efficacy endpoint data from the
VISION trial.

Final VISION trial data are summarized in the table below.

Although  the  original  VISION  study  protocol  was  not  designed  to  follow  patients  beyond  six  months,  in  2016  we  began  working  with  18  of  the
VISION  sites  to  re-consent  patients  in  order  for  them  to  be  evaluated  for  patient  outcomes  through  12  and  24  months  following  initial  treatment.  Data
collection for patients from participating sites was completed in May 2017, and we released the final 12- and 24-month results for a total of 73 patients and 89
lesions in July 2017. The key metrics reported for this group were freedom from target lesion revascularization, or TLR, at 12 months and 24 months, which
were 82% and 74% by patient and 83% and 76% by lesion, respectively, based on Kaplan-Meier curve assessments.

INSIGHT (Pantheris)

The INSIGHT Trial was a prospective, global, single-arm, multi-center trial to evaluate the safety and effectiveness of Pantheris for treating in-stent
restenosis (“ISR”) in lower extremity arteries. ISR occurs when a blocked artery previously treated with a stent becomes narrowed again, thereby reducing
blood  flow.  Physicians  often  face  challenges  when  treating  ISR  both  in  terms  of  safety  and  efficacy.  From  a  safety  standpoint,  limitations  in  imaging
techniques, such X-ray fluoroscopy, and the inability to control the directionality of other atherectomy devices create concerns with impacting the integrity of
the stent during the procedure. In terms of efficacy, current therapies for in-stent restenosis, such as balloon angioplasty, have high rates of recurrent narrowing
within stents.

The INSIGHT trial enrolled 97 patients at sites in the United States and Europe. Patient enrollment began in October 2017 and concluded in July

2021. Patient were evaluated at thirty days, six months and one year following treatment.

The  primary  safety  endpoint  was  defined  as  freedom  from  a  composite  of  major  adverse  events  (MAEs)  through  30  days  after  the  procedure,  as
adjudicated by an independent Clinical Events Committee (CEC). The primary effectiveness endpoint was technical success, defined as the percent of target
lesions that have a residual diameter stenosis ≤ 50% after use of the Pantheris device alone, as assessed by an independent angiographic core laboratory. The
secondary  safety  endpoint  was  absence  of  new  or  worsening  stent  fracture  following  use  of  the  Pantheris  catheter.  A  secondary  powered  effectiveness
endpoint  was  freedom  from  target  lesion  revascularization  (TLR)  at  6  months  following  the  index  procedure.  Additional  secondary  effectiveness  included
procedural  success,  defined  as  the  percent  of  target  lesions  that  have  residual  diameter  stenosis  ≤  30%  post-Pantheris  and  any  other  adjunctive  therapy,  as
determined by an independent core lab, and changes in Ankle- Brachial Index (ABI), and Rutherford Classes at 30 days and 6 months after the procedure in
relation to the measurements prior to the procedure.

The subjects enrolled in the INSIGHT trial presented with documented symptomatic in-stent restenosis (stenosis >70% by visual estimation) and met
all eligibility criteria. The target in-stent restenotic lesion had to be located in vessels with diameters of > 3 mm and < 7 mm and were not to exceed 30 cm in
length.  Subjects  were  followed  through  30  days  and  six  months  post-procedure  for  purposes  of  the  FDA  submission  to  expand  the  indication  for  use
statement. The clinical data for 97 subjects enrolled that reported for clinic visits 30 days and 85 subjects who reported for clinic visits 6 months after the
index procedure were analyzed.

The  primary  safety  endpoint  was  defined  as  freedom  from  a  composite  of  major  adverse  events  (MAEs)  through  30  days  after  the  procedure,  as
adjudicated by an independent Clinical Events Committee (CEC). Only 3 subjects (3%) experienced a MAE, with 97% of subjects free from MAEs within 30
days.  With  only  3%  subjects  reporting  an  MAE  and  a  95%  one-sided  upper  confidence  bound  of  6.5%,  the  primary  safety  performance  goal  of  MAEs
occurring in < 20% of subjects was met.

The  secondary  safety  endpoint  was  absence  of  new  or  worsening  stent  fracture  following  use  of  the  Pantheris  catheter.  Only  one  (1)  catheter
inadvertently made contact with a stent during the 97 procedures, a rate of 1%. This endpoint was not established with a sample size requirement, so this
performance goal was met not only due to its extremely low incidence rate but also by the experience that after re-training the one physician who had this
event on the use of real-time optical coherence tomography imaging during the procedure, he completed 12 subsequent cases with no further events.

The primary effectiveness endpoint of this study was technical success, defined as the percent of target lesions that have a residual diameter stenosis
≤ 50% after use of the Pantheris device alone, as assessed by an independent angiographic core laboratory. In this analysis, 86 out of 97 (89%) subjects had
<50% residual stenosis following use of the Pantheris catheter alone, with a 95% one-sided upper confidence bound of 95% and a lower confidence bound of
82%, which met the adjusted performance goal of > 79%.

A secondary powered effectiveness endpoint was freedom from target lesion revascularization (TLR) at 6 months following the index procedure. The
freedom from TLR of the 85 subjects that have completed their 6-month follow-up visits after the index procedure was 93% (79/85), with a 95% one-sided
upper confidence bound of 98% and a lower bound of 87%, which met the performance goal of > 61%.

Additional secondary effectiveness included procedural success, defined as the percent of target lesions that have residual diameter stenosis ≤ 30%
post-Pantheris  and  any  other  adjunctive  therapy,  as  determined  by  an  independent  core  lab,  and  changes  in  Ankle-  Brachial  Index  (ABI),  and  Rutherford
Classes at 30 days and 6 months after the procedure in relation to the measurements prior to the procedure.

Procedural success was determined if the residual diameter stenosis was < 30% following adjunctive treatment. In this cohort 78 of the 97 subjects

(80%) were determined to have a residual stenosis < 30% following review of angiograms by the core lab, with a mean stenosis of 15% ±10.1%.

The ABI measures improved 39% from baseline by the time of the 6-month visit and the Rutherford Classification measures improved by 71% at the

same time.

Adjunctive devices used in the procedure were primarily balloons (83%), with balloon angioplasty followed by placement of a stent occurring in 13%

of the cases, and no adjunctive treatment provided in 4% of the procedures.

The results from the INSIGHT trial demonstrated that the Pantheris catheter is safe and effective when used to address in-stent restenosis. The study
endpoints achieved the effectiveness performance goals while demonstrating a strong safety profile indicating that the Pantheris catheter can be used to safely
excise tissue from occluded vascular stents with precision. The study results also demonstrate extremely low, acute device-related adverse events.

A 510(k) application to the FDA was submitted in June and the addition of ISR treatment to the indication for use for the Pantheris catheter cleared in

November 2021.

Other Studies

We are pursuing additional clinical data programs including a post-market study, IMAGE-BTK, that is designed to evaluate the safety and efficacy of

Pantheris SV in the treatment of PAD lesions below-the-knee. We are currently enrolling patients and we expect to complete enrollment during 2022.

Sales and Marketing

We focus our sales and marketing efforts primarily on the approximately 10,000 interventional cardiologists, vascular surgeons and interventional
radiologists  in  the  United  States  that  are  potential  users  of  our  Lumivascular  platform  products.  Our  marketing  efforts  are  focused  on  developing  strong
relationships with physicians and hospitals that we have identified as key opinion leaders based on their knowledge of our products, clinical expertise and
reputation.  We  also  use  continuing  medical  education  programs  and  other  opportunities  to  train  interventional  cardiologists,  vascular  surgeons,  and
interventional radiologists in the use of our Lumivascular platform products and educate them as to the benefits of our products as compared to alternative
procedures such as angioplasty, stenting, bypass surgery or other atherectomy procedures. In addition, we work with physicians to help them develop their
practices  and  with  hospitals  to  market  themselves  as  centers  of  excellence  in  PAD  treatment  by  making  our  products  available  to  physicians  for  treating
patients.

Our sales team currently consists of a Vice President, Regional Directors, Territory Sales Managers, Clinical Specialists, and one Vice President of
International Sales. Territory Sales managers are responsible for all product sales, which include disposable catheters and sale and service of our Lightbox
console, while Clinical Specialists are primarily responsible for case coverage and account support. We have an extensive hands-on sales training program,
focused  on  our  technologies,  Lumivascular  image  interpretation,  case  management,  sales  processes,  sales  tools  and  implementing  our  sales  and  marketing
programs and compliance with applicable federal and state laws and regulations. Our sales team is supported by our marketing team, which focuses primarily
on  clinical  training  and  education,  marketing  communications  and  product  management.  We  have  partnered  with  a  third-party  field  service  firm  for  the
installation, service and maintenance of our Lightbox consoles.

For the year ended December 31, 2021, there was one customer that represented 10% of revenues. For the year ended December 31, 2020, there were

no customers that represented 10% or more of revenues.

Competition

The medical device industry is highly competitive, subject to rapid change and significantly affected by new product introductions, results of clinical
research, reimbursement dynamics, corporate combinations and other factors relating to our industry. Because of the market opportunity and the high growth
potential of the PAD treatment market, competitors and potential competitors have historically dedicated, and will continue to dedicate, significant resources
to aggressively develop and commercialize their products.

Our products compete with a variety of products or devices for the treatment of PAD, including other CTO crossing devices, stents, balloons and
atherectomy catheters, as well as products used in vascular surgery. Large competitors in the CTO crossing, stent and balloon market segments include Abbott
Laboratories, AngioDynamics, Becton Dickinson, Boston Scientific, Cardinal Health, Cook Medical, Medtronic and Philips. Competitors in the atherectomy
market  include  AngioDynamics,  Boston  Scientific,  Cardiovascular  Systems,  Medtronic  and  Philips.  Some  competitors  have  attempted  to  combine
intravascular  imaging  with  atherectomy  and  although  we  are  not  aware  of  any  active  initiatives  in  this  area,  these  and  other  companies  may  attempt  to
incorporate  on-board  visualization  into  their  products  in  the  future  or  may  have  ongoing  programs  of  which  we  are  not  aware.  Other  competitors  include
pharmaceutical companies that manufacture drugs for the treatment of symptoms associated with mild to moderate PAD and companies that provide products
used by surgeons in peripheral and coronary bypass procedures. These competitors and other companies may introduce new products that compete with our
solution.

Many of our competitors have substantially greater financial, manufacturing, marketing and technical resources than we do. Furthermore, many of
our  competitors  have  well-established  brands,  widespread  distribution  channels  and  broader  product  offerings,  and  have  established  stronger  and  deeper
relationships with target customers.

10

 
 
 
 
 
 
 
 
 
 
 
 
To compete effectively, we have to demonstrate that our products are attractive alternatives to other devices and treatments on the basis of:

● procedural safety and efficacy;

● acute and long-term outcomes;

● ease of use and procedure time;

● third-party reimbursement;

● size, effectiveness, and productivity of sales force;

● radiation exposure for physicians, hospital staff and patients; and

● price.

Intellectual property

In order to remain competitive, we must develop and maintain protection of the proprietary aspects of our technologies. We rely on a combination of

patents, copyrights, trademarks, trade secret laws and confidentiality and invention assignment agreements to protect our intellectual property rights.

It is our policy to require our employees, consultants, contractors, outside scientific collaborators and other advisors to execute non-disclosure and
assignment of invention agreements on commencement of their employment or engagement. Agreements with our employees also forbid them from using the
proprietary  rights  of  third  parties  in  their  work  for  us.  We  also  require  confidentiality  or  material  transfer  agreements  from  third  parties  that  receive  our
confidential data or materials.

As of December 31, 2021, we held 49 issued and allowed U.S. patents, 3 U.S. pending provisional application, 21 U.S. utility patent applications and
2 PCT applications pending. As of December 31, 2021, we also had 77 issued and allowed patents from outside of the United States. As of December 31,
2021, we had 35 pending patent applications outside of the United States, including in Australia, Canada, China, Europe, India, Japan and Mexico. As we
continue  to  research  and  develop  our  products  and  technology,  we  intend  to  file  additional  U.S.  and  foreign  patent  applications  related  to  the  design,
manufacture and therapeutic uses of our devices. Our issued patents expire between the years 2028 and 2037.

Our patent applications may not result in issued patents and our patents may not be sufficiently broad to protect our technology. Any patents issued to
us may be challenged by third parties as being invalid, or third parties may independently develop similar or competing technology that avoids our patents.
The laws of certain foreign countries do not protect our intellectual property rights to the same extent as do the laws of the United States.

As of December 31, 2021, we held six registered U.S. trademarks. In Europe, we hold three registered trademarks. In the United Kingdom, we hold
three registered trademarks. In addition, we held one International Registration under the Madrid Protocol with granted extensions to China, Europe, Japan,
and Korea (reflected in the three European registrations noted above).

Research and Development

Our ongoing research and development activities are primarily focused on improving and enhancing our Lumivascular platform, specifically our core
competency  of  integrating  OCT  intravascular  imaging  onto  therapeutic  catheters.  Our  research  objectives  target  areas  of  unmet  clinical  need,  increase  the
utility of the Lumivascular platform and adoption of our products by healthcare providers.

● Product line improvements and extensions. We are developing improvements to our Lumivascular platform, including additional catheters for use in
different clinical applications. For example, we are developing next-generation CTO crossing devices to target both the peripheral and coronary CTO
markets.

● Additional treatment indications. We intend to seek additional regulatory clearances from FDA to expand the indications for which our products can
be marketed within PAD, as well as in other areas of the body. This includes both expanding the marketed indications for our current products, as
well as development of new products.

● Improved software and user interface. We intend to further develop our software to provide more information and control to our end users during a

procedure. We use physician and staff feedback to improve the features and user functionality of our Lumivascular platform

In addition to our internal team, we retain third-party contractors from time to time to provide us with assistance on specialized projects. We also

work closely with experts in the medical community to supplement our internal research and development resources.

Manufacturing

All of our products are manufactured in-house using components and sub-assemblies fabricated both at our facility in Redwood City, California and
by key qualified outside vendors. We assemble all of our finished catheter products at our manufacturing facility but certain critical processes such as coating
and sterilization are done by specialized outside vendors. We expect our current manufacturing facility will be sufficient through at least 2022.

Order  quantities  and  lead  times  for  components  purchased  from  outside  suppliers  are  based  on  our  forecasts  derived  from  historical  demand  and
anticipated  future  demand.  Lead  times  for  components  may  vary  significantly  depending  on  the  size  of  the  order,  time  required  to  fabricate  and  test  the
components, specific supplier requirements and current market demand for the components and subassemblies. To date, we have experienced some delays in
obtaining any of our components or subassemblies. Any significant delay or interruption in our supply chain could impair our ability to meet the demands of
our customers and could harm our business.

We rely on single and limited source suppliers for several of our components and sub-assemblies. For example, we rely on single vendors for our
optical fiber, coating and drive cables that are key components of our catheters, and we rely on single vendors for our laser and data acquisition card that are
key components of our Lightbox. These components are critical to our products and there are relatively few alternative sources of supply for them. Identifying
and  qualifying  additional  or  replacement  suppliers  for  any  of  the  components  used  in  our  products  could  involve  significant  time  and  cost.  Any  supply
interruption from our vendors or failure to obtain additional vendors for any of the components used to manufacture our products would limit our ability to
manufacture our products and could therefore harm our business, financial condition and results of operations.

Our manufacturing operations are subject to regulatory requirements of 21 CFR part 820 of the Federal Food, Drug and Cosmetic Act, or FFDCA;
the Quality System Regulation, or QSR, for medical devices sold in the United States, which is enforced by FDA; the Medical Devices Directive 93/42/EEC,
which is required for doing business in the European Union; and applicable requirements relating to the environment, waste management and health and safety
matters, including measures relating to the release, use, storage, treatment, transportation, discharge, disposal and remediation of hazardous substances, and
the sale, labeling, collection, recycling, treatment and disposal of products containing hazardous substances. We cannot ensure that we will not incur material
costs or liability in connection with our operations, or that our past or future operations will not result in claims by or injury to employees or the public.

We have registered with FDA as a medical device manufacturer and have obtained a manufacturing license from the California Department of Public
Health,  or  CDPH.  We  and  our  component  suppliers  are  required  to  manufacture  our  products  in  compliance  with  FDA’s  QSR  in  21  CFR  part  820  of  the
FFDCA. The QSR regulates extensively the methods and documentation of the design, testing, control, manufacturing, labeling, quality assurance, packaging,
storage and shipping of our products. FDA enforces the QSR through periodic unannounced inspections that may include the manufacturing facilities of our
subcontractors. The audit resulted in zero observations or non-conformances. In 2018 and 2019, BSI conducted multiple routine audits including surveillance
audit,  Microbiology  audit,  a  MDSAP  re-certification  audit  and  most  recently,  a  one-day  unannounced  audit  in  September  2019.  Our  Quality  System  has
undergone 20 external audits by third-parties and regulatory authorities since 2009, the latest of which was a surveillance audit conducted in January 2017 by
BSI, our European Notified Body, under the Medical Device Single Audit Program, or MDSAP. All non-conformances identified in the aforementioned audits
have been either successfully resolved or are being actively addressed via Avinger’s CAPA system.

Our  failure  or  the  failure  of  our  component  suppliers  to  maintain  compliance  with  the  QSR  requirements  could  result  in  the  shutdown  of  our
manufacturing operations or the recall of our products, which would harm our business. In the event that one of our suppliers fails to maintain compliance
with our or governmental quality requirements, we may have to qualify a new supplier and could experience manufacturing delays as a result. We have opted
to  maintain  quality  assurance  and  quality  management  certifications  to  enable  us  to  market  our  products  in  the  member  states  of  the  European  Union,  the
European  Free  Trade  Association  and  countries  which  have  entered  into  Mutual  Recognition  Agreements  with  the  European  Union.  Our  Redwood  City
facilities  meet  the  requirements  set  forth  by  ISO  13485:2003  Medical  devices—Quality  management  systems—Requirements  for  regulatory  purposes  and
MDD 93/42/EEC European Union Council Medical Device Directive.

Government Regulation

In general, medical device companies must navigate a challenging regulatory environment. In the United States the FDA regulates the medical device
market  to  ensure  the  safety  and  efficacy  of  these  products.  The  FDA  allows  for  two  primary  pathways  for  a  medical  device  to  gain  approval  for
commercialization: (i) a pre-market notification or 510(k) submission based upon being equivalent to a device already in commercial distribution (a predicate
device) or (ii) a PMA (pre-market approval). A completely novel product must go through the more rigorous PMA process if it cannot receive authorization
through a 510(k) submission. The FDA has established three different classes of medical devices that indicate the level of risk associated with using a device
and consequent degree of regulatory controls needed to govern its safety and efficacy. Class I and Class II devices are considered to have minimal risk to the
user. Some Class I and almost all Class II devices gain clearance for commercial distribution following review of an application to the FDA, generally known
as the 510(k) process. The devices regarded as the highest risk by the FDA are designated Class III and generally require the submission of a PMA application
for approval prior to commercialization. Class III devices generally include life-sustaining, life-supporting, or implantable devices or devices without a known
predicate technology already approved by the FDA.

The 510(k) clearance path can be significantly less time-consuming and less arduous than PMA approval, making this route generally preferable for a
medical device company. A 510(k) application must include documentation that its device is substantially equivalent to a technology already cleared through a
510(k) or in distribution before May 28, 1976, and for which the FDA has not required a PMA submission. The FDA has 90 days from the date of the pre-
market equivalence acceptance to authorize or decline commercial distribution of the device. However, similar to the PMA process, clearance may take longer
than  this  three-month  window,  as  the  FDA  can  request  additional  data  to  support  the  submission.  If  the  FDA  resolves  that  the  product  is  not  substantially
equivalent to a predicate device, then the device acquires a Class III designation, and a PMA must be approved before the device can be commercialized. All
of our currently marketed products have received commercial clearance and associated indications for use through the 510(k) regulatory pathway, some with
the support of clinical data.

After a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a change
in  its  intended  use,  requires  an  additional  510(k)  submission  and  clearance  before  the  modified  device  can  be  commercialized.  The  FDA  allows  each
manufacturer to make this determination initially, but the FDA can review any such decision and can disagree with the manufacturer’s determination. If the
FDA disagrees with the determination not to seek a new 510(k) clearance or PMA the FDA may retroactively require a new 510(k) clearance or pre-market
approval for the modified device. The FDA could also require a manufacturer to cease marketing and distribution of the modified device and/or recall the
modified device until 510(k) clearance or PMA approval is obtained. Also, in these circumstances, a manufacturer may be subject to significant regulatory
fines, penalties, and enforcement actions.

13

 
 
 
 
 
 
 
 
A PMA application must include reasonable scientific and clinical data that demonstrates the device is safe and effective for the intended uses and
indications being sought. The application must also include preclinical testing, technical, manufacturing and labeling information. If the FDA determines the
application can undergo substantive review, it has 180 days to review the submission, but it can typically take longer (up to several years) as this regulatory
body can request additional information or clarifications. The FDA may also impose additional regulatory hurdles for a PMA, including the institution of an
advisory panel of experts to assess the application or provide recommendations as to whether to approve the device. Although the FDA in the end approves or
disapproves the device, in nearly all cases the FDA follows the recommendation from the advisory panel. As part of this process, the FDA will usually inspect
the manufacturing facilities and operations prior to approval to verify compliance with quality control regulations. Significant changes in the manufacturing of
a device, or changes in the intended use, indications and labeling or design of a product require new PMA applications or PMA supplements for a product
originally approved under a PMA. This creates substantial regulatory risk for devices undergoing the PMA route.

Pervasive and Continuing Regulation

After a device is placed on the market, numerous regulatory requirements continue to apply. These include:

● the  FDA’s  QSR  (quality  system  regulation)  that  requires  manufacturers,  including  third-party  manufacturers,  to  follow  stringent  design,  testing,

control, documentation and other quality assurance procedures during all aspects of the manufacturing process;

● labeling regulations and FDA prohibitions against the promotion of products for uncleared, unapproved or off-label uses;

● clearance or approval of product modifications that could significantly affect safety or efficacy or that would constitute a major change in intended

use;

● medical device reporting, or MDR, regulations, that require manufacturers report to the FDA if their device may have caused or contributed to a

death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were to recur;
and

● post-market surveillance regulations, which apply when necessary to protect the public health or to provide additional safety and effectiveness data

for the device.

We  are  registered  with  the  FDA  as  a  medical  device  manufacturer  and  have  obtained  a  manufacturing  license  from  the  California  Department  of
Public Health (CDPH). The FDA has broad post-market and regulatory enforcement powers. We are subject to unannounced inspections by the FDA and the
Food  and  Drug  Branch  of  CDPH  to  determine  our  compliance  with  the  QSR  and  other  regulations,  and  these  inspections  may  include  the  manufacturing
facilities of our suppliers. Our current facility has been inspected by the FDA in 2009, 2011 and 2013, and two, three and zero observations, respectively, were
noted during those inspections. In the latest FDA audit in 2013, there were no observations that involved a material violation of regulatory requirements, and
no  non-conformances  were  noted.  Our  responses  to  the  observations  noted  in  2009  and  2011  were  accepted  by  the  FDA,  and  we  believe  that  we  are  in
substantial  compliance  with  the  QSR.  BSI,  our  European  Notified  Body,  inspected  our  facility  several  times  between  2010  and  2015  and  found  zero  non-
conformances.  BSI  conducted  four  external  audits  in  2016  and  zero  non-conformances  were  found  in  all  except  for  one  audit,  for  which  four  minor  non-
conformances were found. Our Notified Body audit performed in January 2017 resulted in zero non-conformances and an unannounced audit in September
2019, noted only two minor non-conformances, that were addressed promptly and resolved. In 2015, Avinger joined the medical device-single audit program
(MDSAP) that permits audits by our Notified Body to substitute for routine FDA inspections. As of the date of this filing, we have no outstanding unresolved
major non-conformances or findings.

Failure  to  comply  with  applicable  regulatory  requirements  can  result  in  enforcement  action  by  FDA,  which  may  include  any  of  the  following

sanctions:

● warning letters, adverse publicity, fines, injunctions, consent decrees and civil penalties;

● repair, replacement, refunds, recall or seizure of our products;

● operating restrictions, partial suspension or total shutdown of production;

● refusing our requests for 510(k) clearance or pre-market approval of new products, new intended uses or modifications to existing products;

● withdrawing 510(k) clearance or pre-market approvals that have already been granted; and

● criminal prosecution.

Regulatory System for Medical Devices in Europe

The system of regulating medical devices operates by way of a certification for each medical device. Each certificated device is given CE marking
that shows the device has a Certificat de Conformité. There are national bodies known as Competent Authorities in each member state in the EU that oversee
the implementation of the EU’s medical device directive, or MDD, within its jurisdiction. The means of achieving the requirements for CE marking varies
according  to  the  nature  of  the  device.  Devices  are  classified  in  accordance  with  their  perceived  risks,  similarly  to  the  U.S.  system.  The  class  of  a  product
determines  the  requirements  to  be  fulfilled  before  CE  marking  can  be  placed  on  a  product,  known  as  a  conformity  assessment.  Currently  conformity
assessments for our products are carried out as required by the MDD. Each member state can appoint Notified Bodies within its jurisdiction. If a Notified
Body of one member state has issued a Certificat de Conformité, the device can be distributed throughout the European Union without further conformance
tests being required by other member states.

In March 2019, Avinger successfully transferred all current product certificates from BSI-UK to BSI-Netherlands in anticipation of the UK leaving
the  European  Union.  Our  products  currently  with  CE  marking  are  distributed  in  the  EU,  subject  to  the  EU’s  medical  devices  directive,  or  MDD  with
certification renewed in May 2021. In May 2021, we successfully extended the validity of the MDD certificates by 3-years, which will provide certification
until we need to obtain certification under the EU’s new medical device regulation, or MDR, in 2024. We have multiple ongoing efforts to update our quality
management system and product technical documentation to be fully compliant with the MDR requirements before the MDD certificate expires. Until such
time  as  we  are  fully  certified  to  EU  MDR,  we  will  be  highly  limited  in  our  ability  to  make  significant  product  changes  to  existing  design  and  intended
purposes  of  products  (for  distribution  in  the  EU  only)  and/or  will  be  unable  to  launch  new  products  in  the  EU.  Such  limitations  could  harm  our  business,
financial condition, and operating results.

Federal, State and Foreign Fraud and Abuse Laws

Because of the significant federal funding involved in Medicare and Medicaid, Congress and the states have enacted, and actively enforce, a number
of  laws  to  eliminate  fraud  and  abuse  in  federal  healthcare  programs.  Our  business  is  subject  to  compliance  with  these  laws.  In  March  2010,  the  Patient
Protection  and  Affordable  Care  Act,  as  amended  by  the  Healthcare  and  Education  Affordability  Reconciliation  Act,  which  we  refer  to  collectively  as  the
Affordable Care Act, was enacted in the United States. The provisions of the Affordable Care Act are effective on various dates. The Affordable Care Act
expands the government’s investigative and enforcement authority and increases the penalties for fraud and abuse, including amendments to both the Anti-
Kickback Statute and the False Claims Act, to make it easier to bring suit under these statutes. The Affordable Care Act also allocates additional resources and
tools  for  the  government  to  police  healthcare  fraud,  with  expanded  subpoena  power  for  HHS,  additional  funding  to  investigate  fraud  and  abuse  across  the
healthcare system and expanded use of recovery audit contractors for enforcement.

Anti-Kickback  Statutes.        The  federal  Anti-Kickback  Statute  prohibits  persons  from  knowingly  and  willfully  soliciting,  offering,  receiving  or
providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing or arranging for a good or
service,  for  which  payment  may  be  made  under  a  federal  healthcare  program  such  as  Medicare  or  Medicaid.  Violation  of  the  Anti-Kickback  Statue  is  a
criminal felony, and can result in criminal sanctions, civil penalties, enforcement under the False Claims Act, and exclusion from federal healthcare programs.

15

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The  definition  of  “remuneration”  has  been  broadly  interpreted  to  include  anything  of  value,  including,  for  example,  gifts,  certain  discounts,  the
furnishing of free supplies, equipment or services, credit arrangements, payment of cash and waivers of payments. Several courts have interpreted the statute’s
intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered businesses,
the statute has been violated. Penalties for violations include criminal penalties and civil sanctions such as fines, imprisonment and possible exclusion from
Medicare, Medicaid and other federal healthcare programs. In addition, some kickback allegations have been claimed to violate the Federal False Claims Act,
discussed in more detail below.

The Anti-Kickback Statute is broad and prohibits many arrangements and practices that are otherwise lawful in businesses outside of the healthcare
industry. Recognizing that the Anti-Kickback Statute is broad and may technically prohibit many innocuous or beneficial arrangements, Congress authorized
the Office of Inspector General, or OIG, of HHS to issue a series of regulations known as “safe harbors.” These safe harbors set forth provisions that, if all
their applicable requirements are met, will assure healthcare providers and other parties that they will not be prosecuted under the Anti-Kickback Statute. The
failure of a transaction or arrangement to fit precisely within one or more safe harbors does not necessarily mean that it is illegal or that prosecution will be
pursued.  However,  conduct  and  business  arrangements  that  do  not  fully  satisfy  an  applicable  safe  harbor  may  result  in  increased  scrutiny  by  government
enforcement authorities such as OIG.

Many states have adopted laws similar to the Anti-Kickback Statute. Some of these state prohibitions apply to referral of recipients for healthcare

items or services reimbursed by any source, not only the Medicare and Medicaid programs.

Government  officials  have  focused  their  enforcement  efforts  on  the  marketing  of  healthcare  services  and  products,  among  other  activities,  and
recently have brought cases against companies, and certain individual sales, marketing and executive personnel, for allegedly offering unlawful inducements
to potential or existing customers in an attempt to procure their business.

Federal False Claims Act.    Another development affecting the healthcare industry is the increased use of the federal False Claims Act by federal
prosecutors,  and  in  particular,  action  brought  pursuant  to  the  False  Claims  Act’s  “whistleblower”  or  “qui tam”  provisions.  The  False  Claims  Act  imposes
liability on any person or entity that, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment by a federal
healthcare program. The qui tam provisions of the False Claims Act allow a private individual to bring actions on behalf of the federal government alleging
that the defendant has violated the False Claims Act and to share in any monetary recovery. In recent years, the number of suits brought against healthcare
providers by private individuals has increased substantially. In addition, various states have enacted false claims laws analogous to the False Claims Act, and
many of these state laws apply where a claim is submitted to any third-party payor and not just a federal healthcare program.

When an entity is determined to have violated the False Claims Act, it may be required to pay up to three times the actual damages sustained by the
government, plus civil penalties of between $11,665-$23,331 for each separate instance of false claim. As part of any settlement, the government may ask the
entity to enter into a corporate integrity agreement, which imposes certain compliance, certification, and reporting obligations. There are many potential bases
for  liability  under  the  False  Claims  Act.  Liability  arises,  primarily,  when  an  entity  knowingly  submits,  or  causes  another  to  submit,  a  false  claim  for
reimbursement to the federal government. The federal government has used the False Claims Act to assert liability on the basis of inadequate care, kickbacks
and other improper referrals, and improper use of Medicare numbers when detailing the provider of services, in addition to the more predictable allegations as
to  misrepresentations  with  respect  to  the  services  rendered.  In  addition,  the  federal  government  has  prosecuted  companies  under  the  False  Claims  Act  in
connection  with  off-label  promotion  of  products.  Our  future  activities  relating  to  the  reporting  of  wholesale  or  estimated  retail  prices  of  our  products,  the
reporting of discount and rebate information and other information affecting federal, state, and third-party reimbursement of our products and the sale and
marketing of our products may be subject to scrutiny under these laws.

While we are unaware of any current matters, we are unable to predict whether we will be subject to actions under the False Claims Act or a similar
state law, or the impact of such actions. However, the costs of defending such claims, as well as any sanctions imposed, could significantly affect our financial
performance.

16

 
 
 
 
 
 
 
 
 
The Sunshine Act.    The Physician Payment Sunshine Act, or the Sunshine Act, which was enacted as part of the Affordable Care Act, requires all
United States manufacturers of a prescription drug, device, biologic or other medical supply that has been approved or cleared by the FDA, and is available for
coverage by Medicare, Medicaid or the Children’s Health Insurance Program to report annually to the Secretary of HHS: (i) payments or other transfers of
value  made  by  that  entity,  or  by  a  third-party  as  directed  by  that  entity,  to  physicians  and  teaching  hospitals  or  to  third  parties  on  behalf  of  physicians  or
teaching hospitals; and (ii) physician ownership and investment interests in the drug and device manufacturing entity. The payments required to be reported
include the cost of meals provided to a physician, travel reimbursements and other transfers of value, including those provided as part of contracted services
such as speaker programs, advisory boards, consultation services and clinical trial services. Failure to comply with the reporting requirements can result in
significant civil monetary penalties ranging from $1,000 to $10,000 for each payment or other transfer of value that is not reported (up to a maximum per
annual report of $150,000) and from $10,000 to $100,000 for each knowing failure to report (up to a maximum per annual report of $1,150,000). Additionally,
there  are  criminal  penalties  if  an  entity  intentionally  makes  false  statements  in  such  reports.  We  are  subject  to  the  Sunshine  Act  and  the  information  we
disclose  may  lead  to  greater  scrutiny,  which  may  result  in  modifications  to  established  practices  and  additional  costs.  Additionally,  similar  reporting
requirements have also been enacted on the state level domestically, and an increasing number of countries worldwide either have adopted or are considering
similar laws requiring transparency of interactions with healthcare professionals.

Foreign  Corrupt  Practices  Act.        The  Foreign  Corrupt  Practices  Act,  or  FCPA,  prohibits  any  United  States  individual  or  business  from  paying,
offering, or authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party, or candidate for the purpose of
influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates
companies whose securities are listed in the United States to comply with accounting provisions requiring us to maintain books and records that accurately and
fairly  reflect  all  transactions  of  the  corporation,  including  international  subsidiaries,  if  any,  and  to  devise  and  maintain  an  adequate  system  of  internal
accounting controls for international operations.

International  Laws.        In  Europe,  various  countries  have  adopted  anti-bribery  laws  providing  for  severe  consequences,  in  the  form  of  criminal
penalties and/or significant fines, for individuals and/or companies committing a bribery offense. Violations of these anti-bribery laws, or allegations of such
violations, could have a negative impact on our business, results of operations and reputation. For instance, in the United Kingdom, under the Bribery Act
2010, which went into effect in July 2011, a bribery occurs when a person offers, gives, or promises to give a financial or other advantage to induce or reward
another individual to improperly perform certain functions or activities, including any function of a public nature. Bribery of foreign public officials also falls
within the scope of the Bribery Act 2010. Under the new regime, an individual found in violation of the Bribery Act of 2010, faces imprisonment of up to 10
years. In addition, the individual can be subject to an unlimited fine, as can commercial organizations for failure to prevent bribery.

There  are  also  international  privacy  laws  that  impose  restrictions  on  the  access,  use,  and  disclosure  of  health  information.  All  of  these  laws  may
impact  our  business.  Our  failure  to  comply  with  these  privacy  laws  or  significant  changes  in  the  laws  restricting  our  ability  to  obtain  required  patient
information could significantly impact our business and our future business plans.

U.S. Healthcare Reform

Changes in healthcare policy could increase our costs and subject us to additional regulatory requirements that may interrupt commercialization of
our current and future solutions. Changes in healthcare policy could increase our costs, decrease our revenues, and impact sales of and reimbursement for our
current and future solutions. The Affordable Care Act substantially changes the way healthcare is financed by both governmental and private insurers, and
significantly impacts our industry principally by moving healthcare reimbursement towards more value-based and quality-based payment methodologies. The
Act contains a number of provisions that impact our business and operations, some of which in ways we cannot currently predict, including those governing
enrollment in federal healthcare programs and reimbursement changes.

There  will  continue  to  be  proposals  by  legislators  at  both  the  federal  and  state  levels,  regulators  and  third-party  payors  to  reduce  costs  while
expanding individual healthcare benefits. Certain of these changes could impose additional limitations on the prices we will be able to charge for our current
and  future  solutions  or  the  amounts  of  reimbursement  available  for  our  current  and  future  solutions  from  governmental  agencies  or  third-party  payors.
Furthermore,  the  current  presidential  administration  and  Congress  may  again  attempt  broad  sweeping  changes  to  the  current  healthcare  laws.  We  face
uncertainties  that  might  result  from  modification  or  repeal  of  any  of  the  provisions  of  the  Affordable  Care  Act,  including  as  a  result  of  current  and  future
executive  orders  and  legislative  actions.  The  impact  of  those  changes  on  us  and  potential  effect  on  the  medical  device  industry  as  a  whole  is  currently
unknown. But any changes to the Affordable Care Act are likely to have an impact on our results of operations, and may have a material adverse effect on our
results  of  operations.  We  cannot  predict  what  other  healthcare  programs  and  regulations  will  ultimately  be  implemented  at  the  federal  or  state  level  or  the
effect any future legislation or regulation in the United States may have on our business.

17

 
 
 
 
 
 
 
 
 
Third-Party Reimbursement

Payment for patient care in the United States is generally made by third-party payors, including private insurers and government insurance programs,
such  as  Medicare  and  Medicaid.  The  Medicare  program,  the  largest  single  payor  in  the  United  States,  is  a  federal  governmental  health  insurance  program
administered  by  the  Centers  for  Medicare  and  Medicaid  Services,  or  CMS,  and  covers  certain  medical  care  expenses  for  eligible  elderly  and  disabled
individuals.  Because  a  large  percentage  of  the  population  with  PAD  includes  Medicare  beneficiaries,  and  private  insurers  may  follow  the  coverage  and
payment policies of Medicare, Medicare’s coverage and payment policies are significant to our operations.

Medicare pays PAD treatment facilities, including hospitals and physician office-based labs, pre-determined amounts for each procedure performed.

These payment amounts differ based on a variety of factors, including:

•

•

•

•

Type of procedure performed—angioplasty, stent or atherectomy;

Patient-specific complexities and comorbidities;

Type of facility—hospital, teaching hospital or office-based lab;

Inpatient or outpatient status; and

• Geographic region.

We receive payment from the treatment facility for our products, and the Medicare reimbursement to the facility is intended to cover the overall cost
of  treatment,  including  the  cost  of  products  used  during  the  procedure  as  well  as  the  overhead  cost  associated  with  the  facility  where  the  procedure  is
performed.  For  procedures  performed  in  hospitals,  the  physician  who  performs  the  procedure  is  reimbursed  separately  under  the  Medicare  physician  fee
schedule. Claims for PAD procedures are typically submitted by the treatment facility and physician to Medicare or other health insurers using established
billing codes. These codes identify the procedures performed and are relied upon to determine third-party payor reimbursement amounts.

Medicare  reimbursement  for  hospital  outpatient  PAD  procedures  that  include  atherectomy  for  2021  ranged  between  approximately  $10,000  and
$16,000. These amounts include the cost of disposable catheters such as Ocelot and Pantheris. While reimbursement varies based on the type of procedure
performed  (e.g.,  angioplasty,  stent  or  atherectomy),  additional  device-specific  reimbursement  is  not  available.  The  amount  of  reimbursement  can  vary
substantially by geographical region and by facility. Payment rates of other third-party payors may follow Medicare rates, or they may be higher or lower,
depending on their particular reimbursement methodology. Because of the wide variability, it is not possible to identify an average rate for third-party payors
other than Medicare.

Human Capital

As  of  December  31,  2021,  we  had  74  employees,  including  22  in  manufacturing  and  operations,  28  in  sales  and  marketing,  7  in  research  and
development and clinical and regulatory affairs, 5 in quality assurance and 12 in finance, general administrative and executive administration. Of these 74
employees, 6 are part time employees.

None  of  our  employees  are  represented  by  a  labor  union  or  covered  by  a  collective  bargaining  agreement.  We  have  never  experienced  any

employment-related work stoppages and we consider our employee relations to be good.

Although  the  COVID-19  pandemic  has  disrupted  business  and  operations  for  companies  around  the  globe,  the  resilience  of  our  employees  has
enabled us to minimize disruption to our sales, research, clinical studies and operations. Our onsite employees, particularly in manufacturing and operations,
have rapidly adjusted to numerous stringent safety protocols.

We are optimistic about the potential to expand our workforce and create a more inclusive environment for all of our employees.

Diversity, Equity and Inclusion

We understand the importance of diversity in our workforce. We will continue to focus on building a pipeline of opportunities for both the hiring and
advancement  of  qualified  individuals,  including  for  women,  persons  with  disabilities,  and  minority  groups  that  are  underrepresented  in  science  and
engineering industries. We believe that diverse perspectives will help empower our employees, patients and industry.

Communications and Engagement

Our  success  depends  on  employees  understanding  our  strategic  vision  as  well  as  our  day-to-day  objectives.  To  that  end,  we  employ  a  mix  of
communication  and  engagement  channels,  including  all-hands  meetings,  regular  leadership  meetings,  and  quarterly  updates  on  our  progress  against  our
strategic goals. We have also created a cross-functional team focused on improving the employee experience and driving engagement.

A central part of our communications and engagement efforts are connecting people to purpose. To this end, we regularly share stories of physicians
and patients that have been treated with our devices with our employees. Their experiences reinforce our commitment to expand our reach into new patient
populations, geographies and markets.

Health, Safety and Wellness

We are deeply committed to the safety, health and wellness of our employees. The Avinger Environmental, Health & Safety team develops safety
practices and procedures, trains employees, and monitors compliance. Through these efforts, along with leadership commitment and investment of resources
in support of workplace safety initiatives, our total US injury rate has consistently tracked below industry averages.

Compensation

We  recognize  that  our  employees  are  our  most  valuable  asset.  Our  total  rewards  package  includes  market  competitive  pay,  comprehensive  and
competitive benefits and retirement offerings and paid time off and family leave, among other benefits. To foster a stronger sense of ownership and align the
interests of employees with shareholders, we have offered restricted stock units to eligible employees under our broad-based stock incentive programs.

Risk Factor Summary         

The risk factors summarized and detailed below could materially harm our business, operating results and/or financial condition, impair our future
prospects and/or cause the price of our common stock to decline. These are not all of the risks we face and other factors not presently known to us or that we
currently  believe  are  immaterial  may  also  affect  our  business  if  they  occur.  Material  risks  that  may  affect  our  business,  operating  results  and  financial
condition include, but are not necessarily limited to, those relating to:

Risks Related to Our Business

● significant fluctuations in our operating results, our history of net losses and ability to achieve profitability;

● our ability to obtain additional capital on acceptable terms or at all and our significant levels of debt;

● our covenants and restrictions under and our ability to service our Loan Agreement with CRG;

● our reliance on a limited number of products with a limited commercial history;

● our reliance on sales professionals to market and sell our products;

● our ability to demonstrate the benefits of our Lumivascular platform to physicians, hospitals, and patients and our ability to innovate successfully;

Risks Related to Our Business

Our  quarterly  and  annual  results  may  fluctuate  significantly,  may  not  fully  reflect  the  underlying  performance  of  our  business  and  may  result  in
decreases in the price of our common stock.

Our quarterly and annual results of operations, including our revenues, profitability and cash flow, may vary significantly in the future and period-to-
period  comparisons  of  our  operating  results  may  not  be  meaningful.  Accordingly,  the  results  of  any  one  quarter  or  period  should  not  be  relied  upon  as  an
indication of future performance. Our quarterly and annual financial results may fluctuate as a result of a variety of factors, many of which are outside our
control and, as a result, may not fully reflect the underlying performance of our business. Fluctuation in quarterly and annual results may decrease the value of
our common stock. Factors that may cause fluctuations in our quarterly and annual results include, without limitation:

● our ability to obtain and maintain FDA clearance and approval from foreign regulatory authorities for our products, and the timing of such clearances

and approvals, particularly with respect to current and future generations of Pantheris and Ocelot product families;

● market acceptance of our Lumivascular platform and products, including Pantheris, Ocelot and Lightbox;

● the availability of reimbursement for our Lumivascular platform products;

● our ability to attract new customers and increase the amount of business we generate from existing customers;

● results of our clinical trials;

● the timing and success of new product and feature introductions by us or our competitors or any other change in the competitive dynamics of our

industry, including consolidation among competitors, customers or strategic partners;

● the amount and timing of costs and expenses related to the maintenance and expansion of our business and operations;

● changes in our pricing policies or those of our competitors;

● general economic, political, industry and market conditions;

● the regulatory environment;

● the hiring, training and retention of key employees, including our sales team;

● the cost and potential outcomes of any litigation;

● our ability to obtain additional financing; and

● advances and trends in new technologies and industry standards.

In addition, we rely on estimates and forecasts of our expenses and revenues to provide guidance and inform our business strategies, and some of our
past estimates and forecasts have not been accurate. The evolving nature of our business makes forecasting operating results difficult. If we fail to accurately
forecast  our  expenses  and  revenues,  our  business,  prospects,  financial  condition  and  results  of  operations  may  suffer,  and  the  value  of  our  business  may
decline. If our estimates and forecasts prove incorrect, we may not be able to adjust our operations quickly enough to respond to lower-than-expected sales
which,  for  example,  could  result  in  higher  than  anticipated  inventory  levels,  or  higher-than-expected  expenses  which,  for  example,  could  be  the  result  of
building excess capacity.

Based upon the factors above and others beyond our control, we have a limited ability to forecast our future revenue, costs and expenses. If we fail to
meet or exceed the operating results expectations of analysts and investors or if analysts and investors have estimates and forecasts of our future performance
that  are  unrealistic  or  that  we  do  not  meet,  the  market  price  of  our  common  stock  could  decline.  In  addition,  if  one  or  more  of  the  analysts  who  cover  us
adversely  change  their  recommendation  regarding  our  stock,  the  market  price  of  our  common  stock  could  decline.  In  the  past,  companies  that  have
experienced volatility in the market price of their stock have been subject to securities litigation. We may be the target of this type of litigation in the future,
which could result in substantial costs and divert our management’s attention from other business concerns.

You should consider our business in light of the risks and difficulties we may encounter, as described above and elsewhere in this “Risk Factors”

section. If we fail to address the risks and difficulties that we face, our business and operating results will be adversely affected.

We have a history of net losses and we may not be able to achieve or sustain profitability.

We have incurred significant losses in each period since our inception in 2007. We incurred net losses of $17.4 million in 2021 and $19.0 million in
2020.  As  of  December  31,  2021,  we  had  an  accumulated  deficit  of  approximately  $384.8  million.  These  losses  and  our  accumulated  deficit  reflect  the
substantial investments we have made to develop our Lumivascular platform and acquire customers.

We  expect  our  losses  to  continue  for  the  foreseeable  future  as  we  continue  to  make  significant  future  expenditures  to  develop  and  expand  our
business. In addition, as a public company, we will continue to incur significant legal, accounting and other expenses. Accordingly, we cannot assure you that
we  will  achieve  profitability  in  the  future  or  that,  if  we  do  become  profitable,  we  will  sustain  profitability.  Our  failure  to  achieve  and  sustain  profitability
would negatively impact the market price of our common stock.

We  may  not  be  able  to  secure  additional  financing  on  favorable  terms,  or  at  all,  to  meet  our  future  capital  needs  and  our  failure  to  obtain  additional
financing  when  needed  could  force  us  to  delay,  reduce  or  eliminate  our  product  development  programs  and  commercialization  efforts  or  cause  us  to
become insolvent.

We believe that our cash and cash equivalents at December 31, 2021, together with debt and financing activities, including the financing in January
2022, and expected revenues from operations, will be sufficient to satisfy our capital requirements and fund our operations through at least the second quarter
of  2023.  Even  though  we  received  net  proceeds  of  approximately  of  $3.9  million  from  the  sale  of  our  common  stock  in  our  January  2020  offering,  $2.3
million  of  loan  proceeds  in  April  2020  pursuant  to  the  Paycheck  Protection  Program  (“PPP”)  under  the  Coronavirus  Aid,  Relief  and  Economic  Security
(“CARES”) Act, $3.0 million from the sale of our common stock in April and May 2020, $5.5 million from the sale of our common stock in June and July
2020, $11.3 million from the sale of our common stock in August and September 2020, approximately $13.0 million from the sale of our common stock in
February 2021, and approximately $6.7 million from the sale of our Series D Convertible Preferred Stock and common stock purchase warrants in a registered
direct offering in January 2022, we may need to raise additional funds through future equity or debt financings in the near future to meet our operational needs
and capital requirements for product development, clinical trials and commercialization. We can provide no assurance that we will be successful in raising
funds  pursuant  to  additional  equity  or  debt  financings  or  that  such  funds  will  be  raised  at  prices  that  do  not  create  substantial  dilution  for  our  existing
stockholders. Given the volatility of our stock price, any financing that we undertake could cause substantial dilution to our existing stockholders.

To date, we have financed our operations primarily through sales of our products and net proceeds from the issuance of our preferred stock and debt
financings, our initial public offering, or IPO, and our follow-on public offerings. We do not know when or if our operations will generate sufficient cash to
fund our ongoing operations. We cannot be certain that additional capital will be available as needed on acceptable terms, or at all. In the future, we may
require additional capital in order to (i) continue to conduct research and development activities, (ii) conduct post-market clinical studies, as well as clinical
trials  to  obtain  regulatory  clearances  and  approvals  necessary  to  commercialize  our  Lumivascular  platform  products,  (iii)  expand  our  sales  and  marketing
infrastructure,  (iv)  acquire  complementary  businesses  technologies  or  products;  or  (v)  respond  to  business  opportunities,  challenges,  a  decline  in  sales,
increased regulatory obligations or unforeseen circumstances. Our future capital requirements will depend on many factors, including:

● the degree of success we experience in commercializing our Lumivascular platform products, particularly Pantheris, and any future versions of such

products;

● the costs, timing and outcomes of clinical trials and regulatory reviews associated with our future products;

● the costs and expenses of maintaining or expanding our sales and marketing infrastructure and our manufacturing operations;

● the costs and timing of developing variations of our Lumivascular platform products and, if necessary, obtaining FDA clearance of such variations;

● the extent to which our Lumivascular platform is adopted by hospitals for use by interventional cardiologists, vascular surgeons and interventional

radiologists in the treatment of PAD;

● the number and types of future products we develop and commercialize;

● the costs of defending ourselves against future litigation;

23

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims; and

● the extent and scope of our general and administrative expenses.

We  may  raise  additional  funds  in  equity  or  debt  financings  or  enter  into  credit  facilities  in  order  to  access  funds  for  our  capital  needs.  Any  debt
financing obtained by us in the future would cause us to incur additional debt service expenses and could include restrictive covenants relating to our capital
raising  activities  and  other  financial  and  operational  matters,  which  may  make  it  more  difficult  for  us  to  obtain  additional  capital  and  pursue  business
opportunities. In addition, due to our current level of debt, future equity investors may require that we convert all or a portion of our debt to equity, and our
debtholders may not agree to such terms. If we raise additional funds through further issuances of equity or convertible debt securities, and/or if we convert all
or a portion of our existing debt to equity, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any
new  equity  securities  we  issue  could  have  rights,  preferences  and  privileges  senior  to  those  of  holders  of  our  common  stock.  If  we  are  unable  to  obtain
adequate financing or financing on terms satisfactory to us when we require it, we may terminate or delay the development of one or more of our products,
delay clinical trials necessary to market our products, delay establishment of sales and marketing capabilities or other activities necessary to commercialize
our products, and significantly scale back our operations, or we may become insolvent. If this were to occur, our ability to continue to grow and support our
business and to respond to business challenges could be significantly limited.

We have a significant amount of debt, which may adversely affect our ability to operate our business and our financial position and our ability to secure
additional financing in the future.

As  of  December  31,  2021,  we  had  $12.3  million  in  principal,  back-end  fees  and  interest  outstanding  under  a  Term  Loan  Agreement,  or  the  Loan

Agreement, with CRG Partners III L.P. and certain of its affiliated funds (collectively “CRG”). Our significant amount of debt may:

● increase our vulnerability to adverse changes in general economic, industry and competitive conditions;

● require us to dedicate a substantial portion of our cash flow from operations to make payments on our debt, thereby reducing the availability of our

cash flow to fund working capital, capital expenditures and other general corporate purposes;

● limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

● restrict us from exploiting business opportunities;

● make it more difficult to satisfy our financial obligations, including payments on the Loan Agreement;

● place us at a competitive disadvantage compared to our competitors that have less debt obligations; and

● limit  our  ability  to  borrow  additional  funds  for  working  capital,  capital  expenditures,  acquisitions,  debt  service  requirements,  execution  of  our

business strategy or other general corporate purposes on satisfactory terms or at all.

The existence of a substantial amount of debt may make it difficult for us to run our business effectively or raise the capital we need to continue our

operations.

Covenants under the Loan Agreement will restrict our business in many ways.

The Loan Agreement contains various covenants that limit, subject to certain exceptions, our ability to, among other things:

● incur or assume liens;

● incur additional debt or provide guarantees in respect of obligations of other persons;

● issue redeemable stock and preferred stock;

● pay  dividends  or  make  distributions  on  capital  stock,  repurchase,  redeem  or  make  payments  on  capital  stock  or  repay,  repurchase,  redeem,  retire,

defease, acquire or cancel debt prior to the stated maturity thereof;

● make loans, investments or acquisitions;

24

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● create or permit restrictions on the ability of our subsidiaries to pay dividends or make other distributions to us or to guarantee our debt, limit our or

any of our subsidiaries ability to create liens, or make or pay intercompany loans or advances;

● enter into certain transactions with affiliates;

● sell, transfer, license, lease or dispose of our or our subsidiaries’ assets, including the capital stock of our subsidiaries; and

● dissolve, liquidate, consolidate or merge with or into, or sell substantially all of our assets to another person.

In particular, the Loan Agreement, as most recently amended in January 2021, includes a covenant that we maintain a minimum of $3.5 million of
cash and certain cash equivalents, and we will have to achieve minimum revenues of $8.0 million in 2021, $10.0 million in 2022, $12.0 million in 2023, $14.5
million in 2024 and $17.0 million in 2025. If we fail to meet the applicable minimum revenue target in any calendar year, the Loan Agreement provides a cure
right if we prepay a portion of the outstanding principal equal to 2.0 times the revenue shortfall. There can be no assurance as to our future compliance with
the covenants under the Loan Agreement, as amended.

The covenants contained in the Loan Agreement could adversely affect our ability to execute our business strategies by restricting our ability to make
capital expenditures, engage in strategic acquisitions, refinance our outstanding indebtedness, or obtain additional financing. Such restrictions may make it
difficult to plan for or react to changes in market conditions, such as future downturns in our business or the economy in general.

In addition, potential sources of equity financing may decline to invest in our company given the amount of debt and the rights that debt holders have
to get paid before equity holders. In order to facilitate equity investments, future equity investors may require that we convert all or a portion of our debt to
equity, and our debtholders may not agree to such terms. The amount of debt could therefore affect our ability to finance our company and prevent us from
obtaining necessary operating capital as a result.

We may not be able to generate sufficient cash to service our Loan Agreement. If we default on payments or otherwise fail to comply with our obligations
under  our  Loan  Agreement,  the  lender  may  be  able  to  accelerate  amounts  owed  under  the  facility  and  may  foreclose  upon  the  assets  securing  our
obligations.

Borrowings  under  our  Loan  Agreement  are  secured  by  substantially  all  of  our  personal  property,  including  our  intellectual  property.  The  existing
collateral pledged under the Loan Agreement may prevent us from being able to secure additional debt or equity financing on favorable terms, or at all, or to
pursue business opportunities, including potential acquisitions. Our ability to make scheduled payments, comply with our debt covenants, or to refinance our
debt obligations depends on numerous factors, including the amount of our cash reserves and our actual and projected financial and operating performance.
These amounts and our performance are subject to numerous risks, including the risks in this section, some of which may be beyond our control. We cannot
assure you that we will maintain a level of cash reserves or cash flows from operating activities sufficient to permit us to pay the principal, premium, if any,
and interest on our existing or future indebtedness. If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be
forced to reduce or delay capital expenditures, sell assets or operations, seek additional capital or restructure or refinance our indebtedness. We cannot assure
you that we would be able to take any of these actions, or that these actions would permit us to meet our scheduled debt service obligations. In addition, in the
event  of  our  breach  of  the  Loan  Agreement,  we  may  be  required  to  repay  any  outstanding  amounts  earlier  than  anticipated.  If  we  fail  to  comply  with  our
obligations  under  the  Loan  Agreement,  the  lender  would  be  able  to  accelerate  the  required  repayment  of  amounts  due  and,  if  they  are  not  repaid,  could
foreclose upon our assets securing our obligations under the Loan Agreement.

Our success depends in large part on a limited number of products, particularly Pantheris product family, all of which have a limited commercial history.
If these products fail to gain, or lose, market acceptance, our business will suffer.

Ocelot,  Ocelot  PIXL,  Ocelot  MVRX,  Tigereye,  Lightbox  3,  Pantheris  and  Pantheris  SV  are  our  only  products  currently  cleared  for  sale,  and  our
current revenues are wholly dependent on them. In addition, the long-term viability of our company is largely dependent on the successful commercialization
and continued development of the Pantheris product family and we expect that sales of our other current and future Lumivascular platform products in the
United States will account for substantially all of our revenues for the foreseeable future. Accordingly, our success depends on the continued and growing
acceptance and use of Lumivascular platform products by the medical community.

25

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
All  of  our  products  have  a  limited  commercial  history.  For  example,  we  received  510(k)  clearance  from  the  FDA  to  commercialize  Pantheris  in
October 2015 as well as a separate FDA clearance to market enhanced versions of Pantheris in March 2016 and May 2018 and those versions of Pantheris
became  commercially  available  in  the  United  States  and  select  international  markets  promptly  thereafter.  Pantheris  SV  launched  in  July  2019  after  having
received  FDA  clearance  in  April  2019.  Tigereye  launched  in  October  2020  after  having  received  FDA  clearance  in  September  2020.  Our  limited
commercialization experience and number of approved products make it difficult to evaluate our current business and predict our future prospects. We have
encountered and will continue to encounter risks and difficulties frequently experienced by companies in rapidly-changing industries.

Our ability to successfully market Lumivascular platform products will also be limited due to a number of factors including regulatory restrictions in
our labeling. We cannot assure demand for Lumivascular platform products will continue to grow or that our products will significantly penetrate current or
new markets. Market demand for our Lumivascular platform products and physician adoption of these products also may be negatively impacted by product
performance  issues  and  the  need  to  replace  certain  products  in  accordance  with  our  warranty  policy.  Utilization  of  our  products  has  been  less  than  we
anticipated historically. If demand for our Lumivascular platform products does not increase and we cannot sell our products as planned, our financial results
will be harmed. In addition, market acceptance may be hindered if physicians are not presented with compelling data from long-term studies of the safety and
efficacy  of  our  Lumivascular  platform  products  compared  to  alternative  procedures,  such  as  angioplasty,  stenting,  bypass  surgery  or  other  atherectomy
procedures. For example, if patients undergoing treatment with our Lumivascular platform products have retreatment rates higher than or comparable with the
retreatment rates of alternative procedures, it will be difficult to demonstrate the value of our Lumivascular platform products. Any studies we may conduct
comparing our Lumivascular platform with alternative procedures will be expensive, time consuming and may not yield positive results. Physicians will also
need to appreciate the value of real-time imaging in improving patient outcomes in order to change current methods for treating PAD patients. In addition,
demand for our Lumivascular platform products may decline or may not increase as quickly as we expect. Failure of our Lumivascular platform products to
significantly penetrate current or new markets, or our failure to successfully commercialize our products, would harm our business, financial condition and
results of operations.

We are also aware of certain characteristics and features of our Lumivascular platform that may prevent widespread market adoption. For example, in
procedures  using  the  current  model  of  Pantheris,  some  physicians  may  prefer  to  have  a  technician  or  second  physician  assisting  with  the  operation  of  the
catheter as well as a separate technician to operate the Lightbox, potentially making it less financially attractive for physicians and their hospitals and medical
facilities. It may take significant time and expense to modify our products to allow a single physician to operate the entire system and we can provide no
guarantee that we will be able to make such modifications or obtain any additional and necessary regulatory clearances for such modifications. Although the
OCT images created by our Lightbox may make it possible for physicians to reduce the degree to which fluoroscopy and contrast dye are used when using our
Lumivascular  platform  products  compared  to  competing  endovascular  products,  physicians  are  still  using  both  fluoroscopy  and  contrast  dye  in  these
procedures. As a result, risks of complications from radiation and contrast dye are still present and may limit the commercial success of our products. Finally,
it requires training of technicians and physicians to effectively operate our Lumivascular platform products, including interpreting the OCT images created by
our Lightbox, which may affect adoption of our products by physicians.

Our  Lumivascular  products  are  highly  complex  and  the  failure  of  relatively  minor  components  could  result  in  product  failure  or  other  significant
performance issues that may not be discovered until after delivery to customers, which could give rise to claims from our customers or their patients. We have
in  the  past,  and  may  in  the  future,  become  aware  of  performance  issues  with  our  products.  For  example,  prior  to  becoming  commercially  available  on
March  1,  2016,  Pantheris  had  been  used  in  clinical  trials  mainly  in  controlled  situations.  Since  its  commercialization  and  as  more  physicians  have  used
Pantheris, we have received additional feedback on its performance, both positive and negative. We have attempted to address certain of these concerns with
our current version of Pantheris. However, there can be no assurance that the changes and improvements will fully address the performance issues that have
been raised by earlier versions of Pantheris. Our revenue has been adversely impacted by these product performance issues. We also had to incur additional
expenses to make product changes and improvements, and to replace products in accordance with our warranty policy. If future product performance issues
are not resolved and physician concerns not addressed, our reputation could suffer, which could lead to decreased sales of our products.

We rely heavily on our sales professionals to market and sell our products. If we are unable to hire, effectively train, manage, improve the productivity of,
and retain our sales professionals, our business will be harmed, which would impair our future revenue and profitability.

Our success largely depends on our ability to hire, train, manage and improve the productivity levels of our sales professionals. We have experienced
turnover of our sales professionals in the past. The loss of any member of our sales team’s senior management could weaken our sales expertise and harm our
business, and we may not be able to find adequate replacements on a timely basis, or at all. The changes in senior management that have occurred over the
past several years may continue to create instability in our sales force leading to attrition in sales representatives in the future.

26

 
 
 
 
 
 
 
 
Competition for sales professionals who are familiar with and trained to sell our products continues to be strong. We train our sales professionals to
better understand our existing and new product technologies and how they can be positioned against our competitors’ products. These initiatives are intended
to  improve  the  productivity  of  our  sales  professionals  and  our  revenue  and  profitability.  It  takes  time  for  the  sales  professionals  to  become  productive
following  their  hiring  and  training  and  there  can  be  no  assurance  that  sales  representatives  will  reach  adequate  levels  of  productivity,  or  that  we  will  not
experience  significant  levels  of  attrition  in  the  future.  Measures  we  implement  to  improve  the  productivity  may  not  be  successful  and  may  instead  cause
additional departures from our sales organization, or further reduce our revenue, profitability, and harm our business and our stock price may be adversely
impacted as a result. 

Our  ability  to  compete  is  highly  dependent  on  demonstrating  the  benefits  of  our  Lumivascular  platform  to  physicians,  hospitals  and  patients  and  our
ability to innovate new and improved products.

In  order  to  generate  sales,  we  must  be  able  to  clearly  demonstrate  that  our  Lumivascular  platform  is  a  more  effective  treatment  system  than  the
alternatives offered by our competitors. If we are unable to convince physicians that our Lumivascular platform leads to significantly lower rates of restenosis,
or narrowing of the artery, and leads to fewer adverse events during treatment than those using competing technologies, our business will suffer. We must
convince hospitals and physicians that our Lumivascular platform results in significantly better patient outcomes at a competitive overall cost. For example,
we may need to demonstrate that the investment hospitals must make if purchasing our Lightbox and the incremental costs of having a technician or a second
individual  operate  Pantheris  can  be  justified  based  on  the  benefits  to  patients,  physicians  and  hospitals.  If  we  are  unable  to  develop  robust  clinical  data  to
support these claims, we will be unable to convince hospitals and third-party payors of these benefits and our business will suffer.

Our value proposition to physicians and hospitals is largely dependent upon our contention that the rate of arterial damage when physicians are using
our  imaging  products  is  lower  than  with  non-imaging  competing  products.  If  minimizing  arterial  damage  does  not  significantly  impact  patient  outcomes,
meaning  either  (i)  that  restenosis  is  often  triggered  without  disrupting  healthy  arterial  structures  or  (ii)  arteries  can  be  damaged  during  treatment  without
triggering restenosis, then we may be unable to demonstrate our Lumivascular platform’s benefits are any different than competing technologies. Furthermore,
physicians may find our imaging system difficult to use, and we may not be able to provide physicians with adequate training to be able to realize the benefits
of our Lumivascular platform. If physicians do not value the benefits of on-board imaging and the enhanced visualization enabled by our products during an
endovascular  intervention  as  compared  to  our  competitors’  products,  or  do  not  believe  that  such  benefits  improve  clinical  outcomes,  our  Lumivascular
platform products may not be widely adopted.

In order to remain competitive, we must also continue to develop new product offerings and enhancements to our existing Lumivascular platform
products. The market for medical devices in general, and in the PAD market in particular, is highly competitive, dynamic, and marked by rapid and substantial
technological development and product innovation. If we are unable to innovate successfully, our Lumivascular platform products could become obsolete and
our  revenues  would  decline  as  our  customers  purchase  our  competitors’  products.  In  addition,  our  innovation  efforts  may  not  result  in  new  products  that
generate additional revenue. For example, we believe that our next-generation Pantheris and Pantheris SV are important to our future revenues, and we are
devoting a significant portion of our resources to their continued development. However, we do not yet know whether these or any other new offerings will be
well received and broadly accepted by physicians, and if so, whether sales will be sufficient for us to offset costs of development, implementation, support,
operation, sales and marketing. Additionally, new products may subject us to additional risks of product performance, market adoption, customer complaints
and  litigation.  If  sales  of  our  new  product  offerings,  including  are  lower  than  we  expect,  fail  to  gain  anticipated  market  acceptance  or  cause  us  to  expend
additional resources to fix unforeseen problems and develop modifications, our revenues and results of operations may not improve and our business will be
adversely affected.

Our ability to develop, market, and sell our products depends in part upon our working relationships with physicians, and any events that damage those
relationships, or make it more difficult to build and maintain those relationships, could harm our business.

The development, marketing, and sale of our products depends upon our ability to maintain strong working relationships with physicians. We rely on
these  professionals  to  provide  us  with  considerable  knowledge  and  experience  regarding  the  development,  marketing  and  sale  of  our  products.  Physicians
assist us in clinical trials and as researchers, marketing and product consultants and public speakers. If we cannot maintain our strong working relationships
with these professionals and continue to receive their advice and input, the development and marketing of our products could suffer, which could harm our
business, financial condition and results of operations. The medical device industry’s relationship with physicians is under increasing scrutiny by the Office of
Inspector General, or OIG, the Department of Justice, or DOJ, state attorneys general, and other foreign and domestic government agencies. Changes to or our
failure to comply with laws, rules and regulations governing our relationships with physicians, or an investigation into our compliance by the OIG, DOJ, state
attorneys general and other government agencies, could significantly harm our business by damaging our reputation among, or restricting our ability to work
with, physicians.

27

 
 
 
 
 
 
 
 
 
In  addition,  we  target  our  sales  efforts  to  interventional  cardiologists,  vascular  surgeons  and  interventional  radiologists  because  they  are  often  the
physicians  diagnosing  and  treating  both  coronary  artery  disease  and  PAD.  If  these  physicians  are  not  made  aware  of  our  Lumivascular  platform  products,
those patients may instead be surgically treated or treated with an alternative interventional procedure. In addition, there is a significant correlation between
PAD and coronary artery disease, and many physicians do not routinely screen for PAD while screening for coronary artery disease. If we are not successful in
educating physicians about screening for PAD and about the capabilities of our Lumivascular platform products, our ability to increase our revenues may be
impaired.

We  compete  against  companies  that  have  longer  operating  histories,  more  established  products  and  greater  resources,  which  may  prevent  us  from
achieving significant market penetration, increasing our revenues or becoming profitable.

Our products compete with a variety of products and devices for the treatment of PAD, including other CTO crossing devices, stents, balloons and
atherectomy  catheters,  as  well  as  products  used  in  vascular  surgery.  Large  competitors  in  the  CTO  crossing,  stent  and  balloon  markets  include  Abbott
Laboratories, AngioDyamics, Boston Scientific, Cardinal Health, Cook Medical, Becton Dickinson and Medtronic. Competitors in the atherectomy market
include  AngioDyamics,  Boston  Scientific,  Cardiovascular  Systems,  Medtronic  and  Philips.  Some  competitors  have  previously  attempted  to  combine
intravascular imaging with atherectomy and may have current programs underway to do so. These and other companies may attempt to incorporate on-board
visualization  into  their  products  in  the  future  and  may  remain  competitive  with  us  in  marketing  traditional  technologies.  Other  competitors  include
pharmaceutical companies that manufacture drugs for the treatment of symptoms associated with mild to moderate PAD and companies that provide products
used by surgeons in peripheral and coronary bypass procedures. These competitors and other companies may introduce new products that compete with our
products.  Many  of  our  competitors  have  significantly  greater  financial  and  other  resources  than  we  do  and  have  well-established  reputations,  as  well  as
broader product offerings and worldwide distribution channels that are significantly larger and more effective than ours. In addition, competitors with greater
financial resources than ours could acquire other companies to gain enhanced name recognition and market share, as well as new technologies or products that
could  effectively  compete  with  our  existing  products,  which  may  cause  our  revenues  to  decline  and  would  harm  our  business.  Competition  with  these
companies  could  result  in  price-cutting,  reduced  profit  margins  and  loss  of  market  share,  any  of  which  would  harm  our  business,  financial  condition  and
results of operations.

If we are unable to effectively differentiate our products or company from those of our competitors and our business may be adversely affected.

If our manufacturing facility becomes damaged or inoperable, or we are required to vacate the facility, or our electronic systems are compromised, our
ability to manufacture and sell our Lumivascular platform products and to pursue our research and development efforts may be jeopardized.

We currently manufacture and assemble our Lumivascular platform products in-house. Our products are comprised of components sourced from a
variety  of  contract  manufacturers,  with  final  assembly  completed  at  our  facility  in  Redwood  City,  California.  Our  facility  and  equipment,  or  those  of  our
suppliers,  could  be  harmed  or  rendered  inoperable  by  natural  or  man-made  disasters,  including  fire,  earthquake,  terrorism,  flooding  and  power  outages.
Further, our electronic systems may experience service interruptions, denial-of-service and other cyber-attacks, computer viruses or other events. Any of these
may  render  it  difficult  or  impossible  for  us  to  manufacture  products,  pursue  our  research  and  development  efforts  or  otherwise  run  our  business  for  some
period of time. If our facility is inoperable for even a short period of time, the inability to manufacture our current products, and the interruption in research
and development of any future products, may result in harm to our reputation, increased costs, lower revenues and the loss of customers. Furthermore, it could
be costly and time-consuming to repair or replace our facilities and the equipment we use to perform our research and development work and manufacture our
products.

We depend on third-party vendors to manufacture some of our components, coating and sub-assemblies, including some single source suppliers, which
could make us vulnerable to supply shortages and price fluctuations that could harm our business.

We  currently  manufacture  some  of  our  components  and  sub-assemblies  at  our  Redwood  City  facility  and  rely  on  third-party  vendors  for  other
components and sub-assemblies used in our Lumivascular platform. For several of our components and sub-assemblies we rely on single and limited source
suppliers. For example, we rely on single vendors for our optical fiber, coatings and drive cables that are key components of our catheters, and we rely on
single vendors for our laser and data acquisition card that are key components of our Lightbox. These components are critical to our products and there are
relatively few alternative sources of supply. Further, we do not carry a significant inventory of these components. Our reliance on third-party vendors subjects
us to a number of risks that could impact our ability to manufacture our products and harm our business, including:

● interruption of supply resulting from modifications to, or discontinuation of, a supplier’s operations;

● delays in shipments resulting from slowdowns in manufacturing due to the COVID-19 pandemic or other causes, such as government restrictions on

the movement of people and goods;

● delays in product shipments resulting from uncorrected defects, reliability issues or a supplier’s failure to consistently produce quality components;

● price fluctuations due to a lack of long-term supply arrangements with our suppliers for key components;

● inability to obtain adequate supply in a timely manner or on commercially reasonable terms;

● difficulty identifying and qualifying alternative or additional suppliers for components in a timely manner;

● inability of the manufacturer or supplier to comply with QSR as enforced by the FDA and state regulatory authorities;

● inability to control the quality of products manufactured by third parties;

● production delays related to the evaluation and testing of products from alternative suppliers and corresponding regulatory qualifications; and

● delays in delivery by our suppliers due to changes in demand from us or their other customers.

The  ongoing  COVID-19  pandemic,  including  subsequent  variants,  and  measures  taken  in  response  by  governments  and  businesses  worldwide  to
contain  its  spread,  including  quarantines,  facility  closures,  travel  and  logistics  restrictions,  border  controls,  and  shelter  in  place  or  stay  at  home  and  social
distancing  orders,  have  adversely  impacted  and  are  expected  to  continue  to  adversely  impact  global  supply  chain,  manufacturing,  and  logistics  operations.
Shipping  and  freight  delays  have  also  been  increasing  as  port  closures,  port  congestion,  and  shipping  container  and  ship  shortages  have  increased.  To  the
extent the COVID-19 pandemic and other events result in continuation or worsening of manufacturing and shipping delays and constraints, our suppliers of
raw materials and other components may have difficulty obtaining and providing the materials we require to manufacture our products, which could adversely
affect our ability to acquire and maintain adequate inventory and meet demand for our products. In addition, any significant delay or interruption in the supply
of components or sub-assemblies, or our inability to obtain substitute components, sub-assemblies or materials from alternate sources at acceptable prices in a
timely manner, could impair our ability to meet the demand of our customers and harm our business.

We depend on our senior management team and the loss of one or more key employees or an inability to attract and retain highly skilled employees could
harm our business.

Our success largely depends upon the continued services of our executive management team and key employees and the loss of one or more of our
executive officers or key employees could harm us and directly impact our financial results. Our employees may terminate their employment with us at any
time. Changes in our executive management team resulting from the hiring or departure of executives could disrupt our business.

We  must  attract  and  retain  highly  qualified  personnel.  Competition  for  skilled  personnel  is  intense,  especially  for  engineers  with  high  levels  of
experience in designing and developing medical devices and for sales professionals. We have, from time to time, experienced, and we expect to continue to
experience,  difficulty  in  hiring  and  retaining  employees  with  appropriate  qualifications.  Many  of  the  companies  with  which  we  compete  for  experienced
personnel have greater resources than we have. If we hire employees from competitors or other companies, their former employers may attempt to assert that
these employees or we have breached legal obligations, resulting in a diversion of our time and resources and, potentially, damages. In addition, job candidates
and  existing  employees,  particularly  in  the  San  Francisco  Bay  Area,  often  consider  the  value  of  the  stock  awards  they  receive  in  connection  with  their
employment.  If  the  perceived  value  of  our  stock  awards  declines  or  if  we  do  not  make  grants  of  stock-based  incentive  awards,  it  may  harm  our  ability  to
recruit  and  retain  highly  skilled  employees.  In  addition,  we  invest  significant  time  and  expense  in  training  our  employees,  which  increases  their  value  to
competitors  who  may  seek  to  recruit  them.  If  we  fail  to  attract  new  personnel  or  fail  to  retain  and  motivate  our  current  personnel,  our  business  would  be
harmed.

We do not currently intend to devote significant additional resources in the near-term to market our Lumivascular platform internationally, which will
limit our potential revenues from our Lumivascular platform products.

Marketing our Lumivascular platform outside of the United States would require substantial additional sales and marketing, regulatory and personnel
expenses. As part of our product development and regulatory strategy, we plan to expand into select international markets, but we do not currently intend to
devote significant additional resources to market our Lumivascular platform internationally in order to focus our resources and efforts on the U.S. market. Our
decision to market our products primarily in the United States in the near-term will limit our ability to reach all of our potential markets and will limit our
potential sources of revenue. In addition, our competitors will have an opportunity to further penetrate and achieve market share outside of the United States
until such time, if ever, that we devote significant additional resources to market our Lumivascular platform products or other products internationally.

Our ability to utilize our net operating loss carryforwards may be limited.

As  of  December  31,  2021,  we  had  federal  and  state  net  operating  loss  carryforwards,  or  NOLs,  due  to  prior  period  losses  of  $334.4  million  and
$204.8 million, respectively, which if not utilized will begin to expire in 2027 for federal purposes and 2024 for state purposes. Out of the total Federal net
operating loss carryforwards, $76.9 million were generated in years after December 31, 2017 and have no expiration. Subject to certain limitations, NOLs can
be used to offset taxable income for U.S. federal income tax purposes. However, Section 382 of the Internal Revenue Code of 1986, as amended, may limit the
NOLs we may use in any year for U.S. federal income tax purposes in the event of certain changes in ownership of our company. A Section 382 “ownership
change” generally occurs if one or more stockholders or groups of stockholders who own at least 5% of our stock increase their ownership by more than 50
percentage points over their lowest ownership percentage within a rolling three-year period. Similar rules may apply under state tax laws. It is possible that
prior transactions with respect to our stock may have caused, and that future issuances or sales of our stock (including certain transactions involving our stock
that are outside of our control) could cause, an “ownership change.” A number of our common and preferred stock financings over the past year may affect
our ability to use NOLs. If an “ownership change” occurs, Section 382 would impose an annual limit on the amount of pre-ownership change NOLs and other
tax attributes we can use to reduce our taxable income, potentially increasing and accelerating our liability for income taxes, and also potentially causing those
tax attributes to expire unused. Any limitation on using NOLs could (depending on the extent of such limitation and the NOLs previously used) result in our
retaining less cash after payment of U.S. federal income taxes during any year in which we have taxable income (rather than losses) than we would be entitled
to retain if such NOLs were available as an offset against such income for U.S. federal income tax reporting purposes, which could harm our profitability. On
December 22, 2017, the Tax Cuts and Jobs Act, or Tax Act, was enacted into law with many significant changes to the U.S. tax laws. The Tax Act limits the
utilization of NOLs arising in tax years beginning after December 31, 2017 to 80% of taxable income per year. However, existing NOLs that arose in years
prior to December 31, 2017 are not affected by these provisions. Our ability to utilize NOLs arising in future tax periods may be limited by the Tax Act.

The ongoing COVID-19 pandemic and responses thereto have adversely affected and we expect will continue to adversely affect our supply chain,
workforce, approval process, and business operations.

The  ongoing  COVID-19  pandemic,  and  related  government  and  social  responses,  have  resulted  in  widespread  impacts  on  our  industry  and  the
economy in general, including closures of businesses not deemed “essential,” limitations on the availability of elective medical procedures, work stoppages,
slowdowns and delays, work-from-home policies, travel restrictions and cancellation of events, as well as record declines in stock prices, among other effects.
We continue to monitor our operations and government mandates and may elect or be required to temporarily close our offices to protect our employees, and
limit our access to customers and limit customer use of our products as they are required to prioritize resources to address the public healthcare needs arising
from the COVID-19 pandemic. Such disruptions to our activities and operations will negatively impact our business and some of our operating results and
may negatively impact our financial condition.

The duration of COVID-19's impact on our business may be difficult to assess or predict. The widespread pandemic has resulted, and may continue
to result for an extended period, in significant disruption of global financial markets, reducing our ability to access capital, which would negatively affect our
liquidity. Further, quarantines or government reaction or shutdowns could disrupt our supply chain. Travel and import restrictions may also disrupt our ability
to manufacture or distribute our devices. Any import or export or other cargo restrictions related to our products or the raw materials used to manufacture our
products would restrict our ability to manufacture and ship products and harm our business, financial condition and results of operations. Our key personnel
and other employees could also be affected by COVID-19, potentially reducing their availability, and an outbreak such as COVID-19 or the procedures we
take  to  mitigate  its  effect  on  our  workforce  could  reduce  the  efficiency  of  our  operations  or  prove  insufficient.  We  may  delay  or  reduce  certain  spending
related to certain projects until the travel and logistical impacts related to COVID-19 are lifted, which will delay the completion of such projects.

30

 
 
 
 
 
 
 
 
 
In addition, the conduct of clinical trials required to obtain clearance of additional indications and studies gathering post-market data for some of our
products previously cleared by the FDA have been, and we expect may continue to be, affected by the COVID-19 pandemic. Specifically, site initiation and
patient enrollment were delayed for one of our clinical studies, and we experiencing delays in completing the INSIGHT clinical study with the restrictions on
clinical  work.  As  hospital  resources  are  prioritized  for  the  COVID-19  outbreak  and  quarantines  impede  patient  movement  or  interrupt  healthcare  services,
these  and  other  clinical  studies  may  continue  to  be  disrupted.  If  we  are  unable  to  successfully  complete  these  or  other  clinical  studies,  and  thus  obtain
regulatory approvals and efficacy data sought, our business and operating results may be harmed.

While certain jurisdictions have eased or entirely lifted restrictions on performing elective procedures, we cannot be certain that other jurisdictions
will  do  so,  or  that,  as  hospitals  continue  to  ease  restrictions  on  elective  procedures,  patients  will  begin  requesting  such  procedures.  Furthermore,  some
jurisdictions have experienced and continue to experience a resurgence in COVID-19 cases, which has prompted certain hospitals and other medical providers
in such areas to again defer elective procedures or further prolong or reinstate restrictions on such procedures. If other jurisdictions experience a resurgence in
COVID-19 cases, they may also prolong or reinstate restrictions on elective procedures.

The global outbreak of COVID-19 continues to rapidly evolve. The ultimate impact of the COVID-19 outbreak is highly uncertain and subject to
change,  and  its  duration  and  extent  depends  on  factors  such  as  the  evolution  of  variants  of  the  virus,  and  the  development  and  widespread  distribution  of
vaccines. We do not yet know the full extent of potential delays or impacts on our business or the global economy as a whole. However, these effects have
harmed our business, financial condition, and results of operations in the near term and could have a continuing material impact on our operations, sales, and
ability to continue operations.

Customer demand for and our ability to sell and market our products have been and we expect will continue to be adversely affected by the COVID-19
pandemic and responses thereto.

Restrictions on the ability to travel, social distancing policies, orders and restrictions, including those described above, and recommendations and
fears of COVID-19 spreading within medical centers has caused both patients and providers to delay or cancel procedures that use our devices. We are unable
to accurately predict when these policies, orders and restrictions will be relaxed or lifted, and there can be no assurances that patients or providers will restart
procedures that use our devices upon termination of these policies, orders and restrictions, particularly if there remains any continued community outbreak of
COVID-19. A prolonged economic contraction or recession may also result in employer layoffs of their employees in markets where we conduct business,
which could result in lower procedure demand.

Our sales and marketing personnel often rely on in-person and onsite access to healthcare providers which is currently restricted as hospitals reduce
access to essential personnel only. These restrictions have harmed our sales and marketing efforts, and continued restrictions would have a negative impact on
our sales and results of operations. An increase of COVID-19-related hospital admissions may overload hospitals with unexpected patients, thereby delaying
further procedures that use our devices but that are deemed elective by the hospital. In addition, we made temporary salary and work hour reductions, though
we have reverted salaries and hours to prior levels, we and may, in the future, take further actions including reinstating reductions to salary and work hours,
furloughs, restructuring or layoffs, which may negatively impact our workforce and our business.

Disruptions of our supply chain could have a material adverse effect on our operating and financial results

Disruption of our supply chain capabilities due to trade restrictions, political instability, severe weather, natural disasters, public health crises such as
the ongoing COVID-19 pandemic, terrorism, product recalls, port closures, labor supply or stoppages, the financial or operational instability of key suppliers
and carriers, government restrictions or measures, or other reasons could impair our ability to distribute our products. Many industries, including our own, face
supply chain challenges as a result of COVID-19 and other macroeconomic issues, including reduced freight availability and increased costs, port disruption,
manufacturing facility closures, labor shortages and other supply chain disruptions. To the extent we are unable to mitigate the likelihood or potential impact
of such events, there could be a material adverse effect on our operating and financial results. We have and continue to experience supply chain challenges
resulting from COVID-19, specifically related to extended lead times from certain key suppliers. Should these challenges persist or worsen, we may be unable
to  manufacture  enough  inventory  to  meet  the  current  demand  for  our  Lumivascular  products  and  consequently  incur  significant  adverse  effects  on  our
operating and financial results.

31

 
 
 
 
 
 
 
 
 
 
We  may  acquire  other  companies  or  technologies  or  be  the  target  of  strategic  transactions,  which  could  divert  our  management’s  attention,  result  in
additional dilution to our stockholders and otherwise disrupt our operations and harm our operating results.

We  may  in  the  future  seek  to  acquire  or  invest  in  businesses,  applications  or  technologies  that  we  believe  could  complement  or  expand  our
Lumivascular  platform,  enhance  our  technical  capabilities  or  otherwise  offer  growth  opportunities.  The  pursuit  of  potential  acquisitions  may  divert  the
attention of management and cause us to incur various costs and expenses in identifying, investigating and pursuing suitable acquisitions, whether or not they
are consummated. We may not be able to identify desirable acquisition targets or be successful in entering into an agreement with any particular target or
obtain the expected benefits of any acquisition or investment.

To  date,  our  technology  and  product  development  efforts  have  been  organic,  and  we  have  no  experience  in  acquiring  other  businesses.  In  any
acquisition,  we  may  not  be  able  to  successfully  integrate  acquired  personnel,  operations  and  technologies,  or  effectively  manage  the  combined  business
following  the  acquisition.  Acquisitions  could  also  result  in  dilutive  issuances  of  equity  securities,  the  use  of  our  available  cash,  or  the  incurrence  of  debt,
which  could  harm  our  operating  results.  In  addition,  if  an  acquired  business  fails  to  meet  our  expectations,  our  operating  results,  business  and  financial
condition may suffer.

In addition, we sometimes receive inquiries relating to potential strategic transactions, including from third parties who may seek to acquire us. We
will continue to consider and discuss such transactions as we deem appropriate. Such potential transactions may divert the attention of management, and cause
us to incur various costs and expenses in investigating and evaluating such transactions, whether or not they are consummated.

New  product  development  for  the  coronary  artery  disease  market  may  be  challenging,  expensive  and  carries  no  guarantee  of  an  approved  commercial
product.

In order to create more opportunities to grow our revenue base, we must continue to develop new product offerings and enhancements to our existing
Lumivascular  platform  products.  The  market  for  medical  devices  in  general,  and  in  the  coronary  artery  disease  (“CAD”)  market,  is  highly  competitive,
dynamic, and marked by rapid and substantial technological development and product innovation. We believe that a Lumivascular product developed for the
CAD market is important to our future revenues, and we are beginning to devote a significant portion of our resources to its development. Consequently, we
anticipate we will need additional capital to finance this endeavor encompassing the research and development, clinical trials and eventual promotion of any
new CAD product. Even if we are able to obtain additional capital, we may not be successful in the development any new CAD product.

Our team may not have all the necessary qualifications and experience for the development of such a product. Therefore, we may need to attract and
retain highly qualified personnel with specific experience in the coronary industry. Competition for skilled personnel is intense, especially for engineers with
high levels of experience in designing and developing these types of medical devices, and we may not be successful in hiring and retaining employees with
appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than we have. We may also may
not be able to complete development of such products or choose to allocate our financial and other resources elsewhere due to unforeseen circumstances.

Should we develop a CAD product, we will need to conduct a clinical trial. Clinical development is a long, expensive, and uncertain process and is
subject  to  delays  and  the  risk  that  this  product  may  ultimately  prove  unsafe  or  ineffective  in  treating  the  indications  for  which  they  it  will  be  designed.
Completion of clinical trials may take several years or more and failure of the trial can occur at any time. We cannot provide any assurance that our clinical
trials will meet their primary endpoints or that such trials or their results will be accepted by the FDA or foreign regulatory authorities. Even if we achieve
positive early or preliminary results in clinical trials, these results do not necessarily predict final results, and positive results in early trials may not indicate
success  in  later  trials.  Many  companies  in  the  medical  device  industry  have  suffered  significant  setbacks  in  late-stage  clinical  trials,  even  after  receiving
promising results in earlier trials or in the preliminary results from these late-stage clinical trials.

Furthermore,  we  do  not  yet  know  whether  any  new  CAD  product,  if  developed  and  approved,  will  be  well  received  and  broadly  accepted  by
physicians,  and  if  so,  whether  sales  will  be  sufficient  for  us  to  offset  costs  of  development,  implementation,  support,  operation,  sales  and  marketing.
Additionally, such products may subject us to additional risks of product performance, market adoption, customer complaints and litigation. If sales of this
coronary device are lower than we expect, fail to gain anticipated market acceptance or cause us to expend additional resources to fix unforeseen problems and
develop modifications, our revenues and results of operations may not improve and our business will be adversely affected.

Risks Related to Our Use of Technology and Intellectual Property

If our technology infrastructure is compromised, damaged or interrupted by a cybersecurity incident, data security breach or other security problems, our
operating results and financial condition could be adversely affected.

We  use  technology  in  substantially  all  aspects  of  our  business  operations,  and  our  ability  to  serve  customers  most  effectively  depends  on  the
reliability of our technology systems. Cybersecurity incidents can include computer viruses, computer denial-of-service attacks, worms, and other malicious
software programs or other attacks, covert introduction of malware to computers and networks, impersonation of authorized users, and efforts to discover and
exploit any design flaws, bugs, security vulnerabilities or security weaknesses, as well as intentional or unintentional acts by employees or other insiders with
access privileges, intentional acts of vandalism by third parties and sabotage.

In  addition,  our  technology  infrastructure  and  systems  are  vulnerable  to  damage  or  interruption  from  natural  disasters,  power  loss  and
telecommunications failures. Any such disruption to our systems, or the technology systems of third parties on which we rely, the failure of these systems to
otherwise  perform  as  anticipated,  or  the  theft,  destruction,  loss,  misappropriation,  or  release  of  sensitive  and/or  confidential  information  or  intellectual
property,  could  require  us  to  notify  affected  individuals,  federal  or  state  agencies  or  media  outlets  of  the  incident  and  could  result  in  business  disruption,
negative  publicity,  loss  of  customers,  potential  liability,  including  litigation  or  other  legal  actions  against  us  or  the  imposition  of  penalties,  fines,  fees  or
liabilities,  which  may  not  be  covered  by  our  insurance  policies,  and  competitive  disadvantage,  any  or  all  of  which  would  potentially  adversely  affect  our
customer service, decrease the volume of our business and result in increased costs and lower profits. Moreover, a cybersecurity breach could require us to
devote significant management resources to address the problems associated with the breach and to expend significant additional resources to upgrade further
the security measures we employ to protect information against cyber-attacks and other wrongful attempts to access such information, which could result in a
disruption of our operations.

While  we  have  invested,  and  continue  to  invest,  in  technology  security  initiatives  and  other  measures  to  prevent  security  breaches  and  cyber
incidents, as well as disaster recovery plans, these initiatives and measures may not be entirely effective to insulate us from technology disruption that could
result in adverse effects on our results of operations.

We may in the future be a party to intellectual property litigation or administrative proceedings that could be costly and could interfere with our ability to
sell our Lumivascular platform products.

The medical device industry has been characterized by extensive litigation regarding patents, trademarks, trade secrets, and other intellectual property
rights, and companies in the industry have used intellectual property litigation to gain a competitive advantage. It is possible that U.S. and foreign patents and
pending patent applications or trademarks controlled by third parties may be alleged to cover our products, or that we may be accused of misappropriating
third  parties’  trade  secrets.  Additionally,  our  products  include  hardware  and  software  components  that  we  purchase  from  vendors,  and  may  include  design
components that are outside of our direct control. Our competitors, many of which have substantially greater resources and have made substantial investments
in patent portfolios, trade secrets, trademarks, and competing technologies, may have applied for or obtained or may in the future apply for or obtain, patents
or trademarks that will prevent, limit or otherwise interfere with our ability to make, use, sell and/or export our products or to use product names. They may
devote substantial resources towards obtaining claims that cover the design of our atherectomy products to prevent the marketing and selling of competitive
products. We may become a party to patent or trademark infringement or trade secret claims and litigation as a result of these and other third-party intellectual
property rights being asserted against us. The defense and prosecution of these matters are both costly and time consuming. Vendors from whom we purchase
hardware  or  software  may  not  indemnify  us  in  the  event  that  such  hardware  or  software  is  accused  of  infringing  a  third-party’s  patent  or  trademark  or  of
misappropriating a third-party’s trade secret.

Further,  if  such  patents,  trademarks,  or  trade  secrets  are  successfully  asserted  against  us,  this  may  harm  our  business  and  result  in  injunctions
preventing  us  from  selling  our  products,  license  fees,  damages  and  the  payment  of  attorney  fees  and  court  costs.  In  addition,  if  we  are  found  to  willfully
infringe third-party patents or trademarks or to have misappropriated trade secrets, we could be required to pay treble damages in addition to other penalties.
Although  patent,  trademark,  trade  secret,  and  other  intellectual  property  disputes  in  the  medical  device  area  have  often  been  settled  through  licensing  or
similar arrangements, costs associated with such arrangements may be substantial and could include ongoing royalties. We may be unable to obtain necessary
licenses on satisfactory terms, if at all. If we do not obtain necessary licenses, we may not be able to redesign our Lumivascular platform products to avoid
infringement.

33

 
 
 
 
 
 
 
 
 
 
Similarly, interference or derivation proceedings provoked by third parties or brought by the U.S. Patent and Trademark Office, or USPTO, may be
necessary  to  determine  the  priority  of  inventions  or  other  matters  of  inventorship  with  respect  to  our  patents  or  patent  applications.  We  may  also  become
involved in other proceedings, such as re-examination, inter partes review, or opposition proceedings, before the USPTO or other jurisdictional body relating
to our intellectual property rights or the intellectual property rights of others. Adverse determinations in a judicial or administrative proceeding or failure to
obtain necessary licenses could prevent us from manufacturing and selling our Lumivascular platform products or using product names, which would have a
significant adverse impact on our business.

Additionally, we may need to commence proceedings against others to enforce our patents or trademarks, to protect our trade secrets or know-how, or
to  determine  the  enforceability,  scope  and  validity  of  the  proprietary  rights  of  others.  These  proceedings  would  result  in  substantial  expense  to  us  and
significant  diversion  of  effort  by  our  technical  and  management  personnel.  We  may  not  prevail  in  any  lawsuits  that  we  initiate  and  the  damages  or  other
remedies awarded, if any, may not be commercially meaningful. We may not be able to stop a competitor from marketing and selling products that are the
same or similar to our products or from using product names that are the same or similar to our product names, and our business may be harmed as a result.

We  are  aware  of  patents  held  by  third  parties  that  may  be  asserted  against  us  in  litigation  that  could  be  costly  and  could  limit  our  ability  to  sell  our
Lumivascular platform products.

We  are  aware  of  patent  families  related  to  catheter  positioning,  optical  coherence  tomography,  occlusion  cutting  and  atherectomy  owned  by  third
parties.  With  regard  to  atherectomy  patents,  one  of  our  founders,  Dr.  John  Simpson,  founded  FoxHollow  Technologies  prior  to  founding  our  company.
FoxHollow Technologies developed an atherectomy device that is currently sold by Medtronic, and Dr. Simpson and our Chief Technology Officer, Himanshu
Patel, are listed as inventors on patents covering that device that are now held by Medtronic. We are not currently aware of any claims Medtronic has made or
intends to make against us with respect to Pantheris or any other product or product under development. Because of a doctrine known as “assignor estoppel,”
if any of Dr. Simpson’s earlier patents are asserted against us by Medtronic, we may be prevented from asserting an invalidity defense regarding those patents,
and our defense may be compromised. Medtronic has significantly greater financial resources than we do to pursue patent litigation and could assert these
patent  families  against  us  at  any  time.  Adverse  determinations  in  any  such  litigation  could  prevent  us  from  manufacturing  or  selling  Pantheris  or  other
products or products under development, which would significantly harm our business.

Intellectual property rights may not provide adequate protection, which may permit third parties to compete against us more effectively.

In order to remain competitive, we must develop and maintain protection of the proprietary aspects of our technologies. We rely on a combination of
patents, copyrights, trademarks, trade secret laws and confidentiality and invention assignment agreements to protect our intellectual property rights. As of
December  31,  2021,  we  held  49  issued  and  allowed  U.S.  patents,  3  U.S.  pending  provisional  application,  21  U.S.  utility  patent  applications  and  2  PCT
applications pending. As of December 31, 2021, we also had 77 issued and allowed patents from outside of the United States. As of December 31, 2021, we
had 35 pending patent applications outside of the United States, including in Australia, Canada, China, Europe, India, Japan and Mexico. Our patents and
patent  applications  include  claims  covering  key  aspects  of  the  design,  manufacture  and  therapeutic  use  of  OCT  imaging  catheters,  occlusion-crossing
catheters, atherectomy devices and our imaging console. Our patent applications may not result in issued patents and our patents may not be sufficiently broad
to protect our technology. Any patents issued to us may be challenged by third parties as being invalid, or third parties may independently develop similar or
competing technology that avoids our patents. Should such challenges be successful, competitors might be able to market products and use manufacturing
processes that are substantially similar to ours. We may not be able to prevent the unauthorized disclosure or use of our technical knowledge or other trade
secrets by consultants, vendors or former or current employees, despite the existence generally of confidentiality agreements and other contractual restrictions.
Monitoring  unauthorized  use  and  disclosure  of  our  intellectual  property  is  difficult,  and  we  do  not  know  whether  the  steps  we  have  taken  to  protect  our
intellectual property will be adequate. In addition, the laws of many foreign countries will not protect our intellectual property rights to the same extent as the
laws of the United States. Consequently, we may be unable to prevent our proprietary technology from being exploited abroad, which could affect our ability
to expand to international markets or require costly efforts to protect our technology. To the extent our intellectual property protection is incomplete, we are
exposed to a greater risk of direct competition. In addition, competitors could purchase our products and attempt to replicate some or all of the competitive
advantages  we  derive  from  our  development  efforts  or  design  around  our  protected  technology.  Our  failure  to  secure,  protect  and  enforce  our  intellectual
property rights could substantially harm the value of our Lumivascular platform, brand and business.

We use certain open source software in all versions of our Lightbox. We may face claims from companies that incorporate open source software into
their products or from open source licensors, claiming ownership of, or demanding release of, the source code, the open source software or derivative works
that  were  developed  using  such  software,  or  otherwise  seeking  to  enforce  the  terms  of  the  applicable  open  source  license.  These  claims  could  result  in
litigation  and  could  require  us  to  cease  offering  Lightbox  unless  and  until  we  can  re-engineer  it  to  avoid  infringement.  This  re-engineering  process  could
require  significant  additional  research  and  development  resources,  and  we  may  not  be  able  to  complete  it  successfully.  These  risks  could  be  difficult  to
eliminate or manage, and, if not addressed, could harm our business, financial condition and operating results.

Regulatory and Litigation Risks

If we fail to obtain and maintain necessary regulatory clearances or approvals for our Lumivascular platform products, or if clearances or approvals for
future products and indications are delayed or not issued, our commercial operations would be harmed.

Our  Lumivascular  platform  products  are  medical  devices  that  are  subject  to  extensive  regulation  by  FDA  in  the  United  States  and  by  regulatory

agencies in other countries where we do business. Government regulations specific to medical devices are wide-ranging and govern, among other things:

● product design, development and manufacture;

● laboratory, preclinical and clinical testing, labeling, packaging, storage and distribution;

● pre-marketing clearance or approval;

● record keeping;

● product marketing, promotion and advertising, sales and distribution; and

● post-marketing surveillance, including reporting of deaths or serious injuries and recalls and correction and removals.

Before a new medical device, or a new intended use for, an existing product can be marketed in the United States, a company must first submit and
receive  either  510(k)  clearance  or  pre-marketing  approval  from  FDA,  unless  an  exemption  applies.  Either  process  can  be  expensive,  lengthy  and
unpredictable. We may not be able to obtain the necessary clearances or approvals or may be unduly delayed in doing so, which could harm our business.
Furthermore, even if we are granted regulatory clearances or approvals, they may include significant limitations on the indicated uses for the product, which
may limit the market for the product. Although we have obtained 510(k) clearance to market our Pantheris family of catheters for atherectomy, and our Ocelot
family of catheters for crossing sub and total occlusions in the peripheral vasculature, our clearance can be revoked if safety or efficacy problems develop.
Delays in obtaining clearance or approval could increase our costs and harm our revenues and growth.

In addition, we are required to timely file various reports with the FDA, including medical device reports, or MDRs, if our devices may have caused
or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were
to recur. If these MDRs are not filed timely, regulators may impose sanctions and sales of our products may suffer, and we may be subject to product liability
or regulatory enforcement actions, all of which could harm our business.

If we initiate a correction or removal for one of our devices to reduce a risk to health posed by the device, we would be required to submit a publicly
available Correction and Removal report to the FDA and in many cases, similar reports to other regulatory agencies. This report could be classified by the
FDA as a device recall that could lead to increased scrutiny by the FDA, other international regulatory agencies and our customers regarding the quality and
safety of our devices. Furthermore, the submission of these reports has been and could be used by competitors against us in competitive situations and cause
customers to delay purchase decisions or cancel orders and would harm our reputation.

The FDA and the Federal Trade Commission, or FTC, also regulate the advertising and promotion of our products to ensure that the claims we make
are consistent with our regulatory clearances, that there are adequate and reasonable scientific data to substantiate the claims and that our promotional labeling
and advertising is neither false nor misleading in any respect. If the FDA or FTC determines that any of our advertising or promotional claims are misleading,
not substantiated or not permissible, we may be subject to enforcement actions, including Warning Letters, adverse publicity, and we may be required to revise
our promotional claims and make other corrections or restitutions.

The  FDA  and  state  authorities  have  broad  enforcement  powers.  Our  failure  to  comply  with  applicable  regulatory  requirements  could  result  in
enforcement  action  by  the  FDA  or  state  agencies,  which  may  include,  among  other  things,  harm  to  our  reputation;  fines,  injunctions,  civil  penalties,  or
criminal  prosecution;  product  replacements  or  recalls;  or  rejecting  our  requests  for  future  510(k)  clearance  or  pre-market  approval  or  withdrawal  of  a
previously granted 510(k) clearance. If any of these events were to occur, our business and financial condition would be harmed.

Material modifications to our Lumivascular platform products may require new 510(k) clearances or pre-market approvals or may require us to recall or
cease marketing our Lumivascular platform products until clearances or approvals are obtained.

Material modifications to the intended use or technological characteristics of our Lumivascular platform products will require new 510(k) clearances
or pre-market approvals or require us to recall or cease marketing the modified devices until these clearances or approvals are obtained if such changes were
made via the “Letter-to-File” process of internal documentation. Based on published FDA guidelines, the FDA requires device manufacturers to initially make
and  document  a  determination  of  whether  or  not  a  modification  requires  a  new  approval,  supplement  or  clearance;  however,  the  FDA  can  review  a
manufacturer’s  decision.  Any  modification  to  an  FDA-cleared  device  that  would  significantly  affect  its  safety  or  efficacy  or  that  would  constitute  a  major
change in its intended use would require a new 510(k) clearance or possibly a pre-market approval. We may not be able to obtain additional 510(k) clearances
or pre-market approvals for new products or for modifications to, or additional indications for, our Lumivascular platform products in a timely fashion, or at
all. Delays in obtaining required future clearances would harm our ability to introduce new or enhanced products in a timely manner, which in turn would
harm our future growth. We have made modifications to our Lumivascular platform products in the past and will make additional modifications in the future
that  we  believe  do  not  or  will  not  require  additional  clearances  or  approvals.  If  the  FDA  disagrees  and  requires  new  clearances  or  approvals  for  the
modifications, we may be required to recall and to stop selling or marketing our Lumivascular platform products as modified, which could harm our operating
results and require us to redesign our Lumivascular platform products. In these circumstances, we may be subject to significant enforcement actions. Future
versions of are Lumivacular platform incorporating enhancements may require additional regulatory clearances or approvals.

Our ability to market our current products in the United States is limited to use in peripheral vessels, and if we want to market our products for other uses,
we will need to file for FDA clearances or approvals and may need to conduct trials to support expanded use, which would be expensive, time-consuming
and may not be successful.

Our current products are cleared in the United States only for crossing sub-total and chronic total occlusions and for performing atherectomy in the
peripheral  vasculature.  These  FFDCA  clearances  prohibits  us  from  marketing  or  advertising  our  products  for  any  other  indication  within  the  peripheral
vasculature, which restricts our ability to sell these products and could affect our growth. Additionally, our products are contraindicated for use in the cerebral,
carotid, coronary, iliac, and renal arteries. While off-label use of medical devices is common and the FDA does not regulate physicians’ choice of treatments,
the FDA does restrict a manufacturer’s communications regarding such off-label use. We are not allowed to actively promote or advertise our products for off-
label use. In addition, we cannot make comparative claims regarding the use of our products against any alternative treatments without conducting head-to-
head comparative clinical studies, which would be expensive and time consuming. If our promotional activities fail to comply with the FDA’s regulations or
guidelines, we may be subject to warnings or enforcement action by the FDA and other government agencies. In the future, if we want to market a variation of
Ocelot  or  Pantheris  product  families  in  the  United  States  for  use  in  other  applications  for  which  we  do  not  currently  have  clearance,  such  as  the  coronary
arteries, we will need to make modifications to these products, conduct further clinical trials and obtain new clearances or approvals from the FDA. There can
be no assurance that we will successfully develop these modifications, that future clinical studies will be successful or that the expense of these activities will
be offset by additional revenues.

If our clinical trials are unsuccessful or significantly delayed, or if we do not complete our clinical trials, our business may be harmed.

Clinical development is a long, expensive, and uncertain process and is subject to delays and the risk that products may ultimately prove unsafe or
ineffective in treating the indications for which they are designed. Completion of clinical trials may take several years or more and failure of the trial can occur
at any time. We cannot provide any assurance that our clinical trials will meet their primary endpoints or that such trials or their results will be accepted by the
FDA or foreign regulatory authorities. Even if we achieve positive early or preliminary results in clinical trials, these results do not necessarily predict final
results, and positive results in early trials may not indicate success in later trials. Many companies in the medical device industry have suffered significant
setbacks in late-stage clinical trials, even after receiving promising results in earlier trials or in the preliminary results from these late-stage clinical trials.

36

 
 
 
 
 
 
 
 
 
We  may  experience  numerous  unforeseen  events  during,  or  because  of,  the  clinical  trial  process  that  could  delay  or  prevent  us  from  receiving

regulatory clearance or approval for new products or modifications of existing products, including new indications for existing products, including:

● negative or inconclusive results that may cause us to decide, or regulators may require us, to conduct additional clinical and/or preclinical testing

which may be expensive and time consuming;

● trial results that do not meet the level of statistical significance required by the FDA or other regulatory authorities;

● findings by the FDA or similar foreign regulatory authorities that the product is not sufficiently safe for investigational use in humans;

● interpretations of data from preclinical testing and clinical testing by the FDA or similar foreign regulatory authorities that may be different from our

own;

● delays or failure to obtain approval of our clinical trial protocols from the FDA or other regulatory authorities;

● delays in obtaining institutional review board approvals or government approvals to conduct clinical trials at prospective sites;

● findings by the FDA or similar foreign regulatory authorities that our or our suppliers’ manufacturing processes or facilities are unsatisfactory;

● changes in the review policies of the FDA or similar foreign regulatory authorities or the adoption of new regulations that may negatively affect or

delay our ability to bring a product to market or receive approvals or clearances to treat new indications;

● trouble in managing multiple clinical sites;

● delays in agreeing on acceptable terms with third-party research organizations and trial sites that may help us conduct the clinical trials; and

● the suspension or termination by us, or regulators, of our clinical trials because the participating patients are being exposed to unacceptable health

risks.

Failures or perceived failures in our clinical trials will delay and may prevent our product development and regulatory approval process, damage our

business prospects and negatively affect our reputation and competitive position.

From time to time, we engage outside parties to perform services related to certain of our clinical studies and trials, and any failure of those parties to
fulfill their obligations could increase costs and cause delays.

From time to time, we engage consultants to help design, monitor, and analyze the results of certain of our clinical studies and trials. The consultants
we engage interact with clinical investigators to enroll patients in our clinical trials. We depend on these consultants and clinical investigators to help facilitate
the clinical studies and trials and monitor and analyze data from these studies and trials under the investigational plan and protocol for the study or trial and in
compliance with applicable regulations and standards, commonly referred to as good clinical practices. We may face delays in our regulatory approval process
if these parties do not perform their obligations in a timely, compliant or competent manner. If these third parties do not successfully carry out their duties or
meet expected deadlines, or if the quality, completeness or accuracy of the data they obtain is compromised due to the failure to adhere to our clinical trial
protocols or for other reasons, our clinical studies or trials may be extended, delayed or terminated or may otherwise prove to be unsuccessful, and we may
have to conduct additional studies, which would significantly increase our costs, in order to obtain the regulatory clearances that we need to commercialize our
products.

We have limited long-term data regarding the safety and efficacy of our Lumivascular platform products, including Pantheris. Any long-term data that is
generated by clinical trials involving our Lumivascular platform may not be positive or consistent with our short-term data, which would harm our ability
to obtain clearance to market and sell our products.

Our Lumivascular platform is a novel system, and our success depends on its acceptance by the medical community as being safe and effective, and
improving  clinical  outcomes.  Important  factors  upon  which  the  efficacy  of  our  Lumivascular  platform  products,  including  Pantheris,  will  be  measured  are
long-term data on the rate of restenosis following our procedure, and the corresponding duration of patency, or openness of the artery, and publication of that
data in peer-reviewed journals. Another important factor that physicians will consider is the rate of reintervention, or retreatment, following the use of our
Lumivascular platform products. The long-term clinical benefits of procedures that use our Lumivascular platform products are not known.

The results of short-term clinical experience of our Lumivascular platform products do not necessarily predict long-term clinical benefit. Restenosis
rates  typically  increase  over  time.  We  believe  that  physicians  will  compare  the  rates  of  long-term  restenosis  and  reintervention  for  procedures  using  our
Lumivascular platform products against alternative procedures, such as angioplasty, stenting, bypass surgery and other atherectomy procedures. If the long-
term rates of restenosis and reintervention do not meet physicians’ expectations, our Lumivascular platform products may not become widely adopted and
physicians may consider alternative treatments for their patients. Another significant factor that physicians will consider is acute safety data on complications
that  occur  during  the  use  of  our  Lumivascular  platform  products.  If  the  results  obtained  from  any  post-market  studies  that  we  conduct  or  post-clearance
surveillance indicate that the use of our Lumivascular platform products are not as safe or effective as other treatment options or as current short-term data
would suggest, adoption of our product may suffer and our business would be harmed. In addition, we are responsible for the costs associated with conducting
studies to obtain safety and efficacy data. If we are unable to obtain sufficient financing, whether through our operations or from third parties, we will not be
able to conduct the studies necessary to obtain long-term data regarding the safety and efficacy of our products.

Even if we believe the data collected from clinical studies or clinical experience indicate positive results, each physician’s actual experience with our
products will vary. Physicians who are technically proficient participate in our clinical trials and are high-volume users of our Lumivascular platform products.
Consequently, the results of our clinical trials and their experiences using our products may lead to better patient outcomes than those of physicians that are
less proficient, perform fewer procedures or who use our products infrequently.

If we or our suppliers fail to comply with the FDA’s QSR, our manufacturing operations could be delayed or shut down and Lumivascular platform sales
could suffer.

Our manufacturing processes and those of our third-party suppliers are required to comply with the FDA’s QSR, which covers the procedures and
documentation of the design, testing, production, control, quality assurance, labeling, packaging, storage and shipping of our Lumivascular platform products.
We are also subject to similar state requirements and licenses. In addition, we must engage in extensive recordkeeping and reporting and must make available
our manufacturing facilities and records for periodic unannounced inspections by governmental agencies, including the FDA, state authorities and comparable
agencies  in  other  countries.  If  we  fail  a  QSR  inspection,  our  operations  could  be  disrupted  and  our  manufacturing  interrupted.  Failure  to  take  adequate
corrective action in response to an adverse QSR inspection could result in, among other things, a shut-down of our manufacturing operations, significant fines,
suspension  of  marketing  clearances  and  approvals,  seizures  or  recalls  of  our  device,  operating  restrictions  and  criminal  prosecutions,  any  of  which  would
cause  our  business  to  suffer.  Furthermore,  our  key  component  suppliers  may  not  currently  be  or  may  not  continue  to  be  in  compliance  with  applicable
regulatory requirements, which may result in manufacturing delays for our products and cause our revenues to decline.

We have registered with the FDA as a medical device manufacturer and have obtained a manufacturing license from the California Department of
Public Health (CDPH). The FDA has broad post-market and regulatory enforcement powers. We are subject to unannounced inspections by the FDA and the
Food  and  Drug  Branch  of  CDPH  to  determine  our  compliance  with  the  QSR  and  other  regulations,  and  these  inspections  may  include  the  manufacturing
facilities of our suppliers. We have undergone numerous audits, inspections, and reviews by the FDA, CDPH, and BSI, our European Notified Body, in the
past, some of which resulted in the identification of instances of non-compliance which we were required to correct. We expect that we will undergo additional
audits, inspections, and reviews in the future, which could result in further corrective actions.

We can provide no assurance that we will continue to remain in substantial compliance with the QSR. If the FDA, CDPH or BSI inspect our facility
and discover major compliance problems, we may have to shut down our facility and cease manufacturing until we can take the appropriate remedial steps to
correct the audit findings. Taking corrective action may be expensive, time consuming and a distraction for management and if we experience a shutdown or
delay at our manufacturing facility, we may be unable to produce our Lumivascular platform products, which would harm our business.

38

 
 
 
 
 
 
 
 
 
 
Our Lumivascular platform products may in the future be subject to product recalls that could harm our reputation.

FDA  and  similar  governmental  authorities  in  other  countries  have  the  authority  to  require  the  recall  of  commercialized  products  in  the  event  of
material regulatory deficiencies or defects in design or manufacture. A government mandated or voluntary recall by us could occur as a result of component
failures, manufacturing errors or design or labeling defects. Recalls of our Lumivascular platform products or products we commercialize in the future would
divert  managerial  attention,  be  expensive,  harm  our  reputation  with  customers  and  harm  our  financial  condition  and  results  of  operations.  A  recall
announcement would negatively affect our stock price.

Changes  in  coverage  and  reimbursement  for  procedures  using  our  Lumivascular  platform  products  could  affect  the  adoption  of  our  Lumivascular
platform and our future revenues.

Currently, our Lumivascular platform procedure is typically reimbursed by third-party payors, including Medicare and private healthcare insurance
companies, under existing reimbursement codes. These payors may change their coverage and reimbursement policies, as well as payment amounts, in a way
that would prevent or limit reimbursement for our products, which would significantly harm our business. Also, healthcare reform legislation or regulation
may  be  proposed  or  enacted  in  the  future,  which  may  adversely  affect  such  policies  and  amounts.  We  cannot  predict  whether  and  to  what  extent  existing
coverage  and  reimbursement  will  continue  to  be  available.  If  physicians,  hospitals  and  other  providers  are  unable  to  obtain  adequate  coverage  and
reimbursement  for  procedures  performed  using  our  Lumivascular  platform  products,  they  are  significantly  less  likely  to  use  our  Lumivascular  platform
products and our business would be harmed.

Healthcare reform measures could hinder or prevent our planned products’ commercial success.

In the United States, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system
in ways that could harm our future revenues and profitability and the future revenues and profitability of our potential customers. Federal and state lawmakers
regularly propose and, at times, enact legislation that would result in significant changes to the healthcare system, some of which are intended to contain or
reduce the costs of medical products and services. The current presidential administration and Congress may continue to attempt broad sweeping changes to
the current healthcare laws. We face uncertainties that might result from modifications or repeal of any of the provisions of the Affordable Care Act, including
as a result of current and future executive orders and legislative actions. The impact of those changes on us and potential effect on the medical device industry
as a whole is currently unknown. Any changes to the Affordable Care Act are likely to have an impact on our results of operations and may have a material
adverse effect on our results of operations. We cannot predict what other healthcare programs and regulations will ultimately be implemented at the federal or
state level or the effect of any future legislation or regulation in the United States may have on our business.

The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or

reduce costs of healthcare may harm:

● our ability to set a price that we believe is fair for our products;

● our ability to generate revenues and achieve or maintain profitability; and

● the availability of capital.

If  we  fail  to  comply  with  healthcare  regulations,  we  could  face  substantial  penalties  and  our  business,  operations  and  financial  condition  could  be
adversely affected.

Even though we do not and will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payors, certain
federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. We are subject to
many  healthcare  fraud  and  abuse  and  patient  privacy  regulations  by  both  the  federal  government  and  the  states  in  which  we  conduct  our  business.  The
regulations that affect how we operate include:

● the  federal  healthcare  program  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  any  person  from  knowingly  and  willfully  offering,
soliciting,  receiving  or  providing  remuneration,  directly  or  indirectly,  in  exchange  for  or  to  induce  either  the  referral  of  an  individual  for,  or  the
purchase, order or recommendation of, any good or service for which payment may be made under federal healthcare programs, such as the Medicare
and Medicaid programs;

● the federal False Claims Act, which prohibits, among other things, individuals or entities from knowingly presenting, or causing to be presented, false

claims, or knowingly using false statements, to obtain payment from the federal government;

39

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare

matters;

● the Sunshine Act, created under the Affordable Care Act, and its implementing regulations, which require manufacturers of drugs, medical devices,
biologicals  and  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid,  or  the  Children’s  Health  Insurance  Program  to  report
annually to the HHS information related to payments or other transfers of value made to physicians and teaching hospitals, as well as ownership and
investment interests held by physicians and their immediate family members;

● HIPAA, as amended by the HITECH Act, which protects the security and privacy of protected health information; and

● state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed

by any third-party payor, including commercial insurers.

The  Affordable  Care  Act,  among  other  things,  amends  the  intent  requirement  of  the  Federal  Anti-Kickback  Statute  and  criminal  healthcare  fraud
statutes.  A  person  or  entity  no  longer  needs  to  have  actual  knowledge  of  this  statute  or  specific  intent  to  violate  it.  In  addition,  the  Affordable  Care  Act
provides that 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 False Claims Act.

Efforts  to  ensure  that  our  business  arrangements  will  comply  with  applicable  healthcare  laws  may  involve  substantial  costs.  It  is  possible  that
governmental  and  enforcement  authorities  will  conclude  that  our  business  practices  do  not  comply  with  current  or  future  statutes,  regulations  or  case  law
interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we are not successful in
defending  ourselves  or  asserting  our  rights,  those  actions  could  have  a  significant  impact  on  our  business,  including  the  imposition  of  civil,  criminal  and
administrative penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare
programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could harm our
ability to operate our business and our results of operations. In addition, the clearance or approval and commercialization of any of our products outside the
United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws.

Compliance with environmental laws and regulations could be expensive. Failure to comply with environmental laws and regulations could subject us to
significant liability.

Our research and development and manufacturing operations involve the use of hazardous substances and are subject to a variety of federal, state,
local and foreign environmental laws and regulations relating to the safe storage, use, discharge, disposal, remediation of, and human exposure to, hazardous
substances  and  the  sale,  labeling,  collection,  recycling,  treatment  and  disposal  of  products  containing  hazardous  substances,  such  as  isopropyl  alcohol  and
other solvents. In addition, our research and development may acquire biological waste materials, such as human and animal tissue, for the sole use of product
design  testing.  Upon  completion  of  the  product  testing,  these  biological  wastes  are  safely  disposed  of  following  all  federal,  state,  local  and  foreign
environmental  laws  and  regulations.  These  operations  are  permitted  by  regulatory  authorities,  and  the  resultant  waste  materials  are  disposed  of  in  material
compliance with environmental laws and regulations. Liability under environmental laws and regulations can be joint and several and without regard to fault
or negligence. Compliance with environmental laws and regulations may be expensive and non-compliance could result in substantial liabilities, fines and
penalties,  personal  injury  and  third-party  property  damage  claims  and  substantial  investigation  and  remediation  costs.  Environmental  laws  and  regulations
could become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations. We cannot assure you
that violations of these laws and regulations will not occur in the future or have not occurred in the past as a result of human error, accidents, equipment failure
or other causes. The expense associated with environmental regulation and remediation could harm our financial condition and operating results.

The use, misuse or off-label use of the products in our Lumivascular platform may result in injuries that lead to product liability suits, which could be
costly to our business.

We require limited training in the use of our Lumivascular platform products because we market primarily to physicians who are experienced in the
interventional techniques required to use our device. If demand for our Lumivascular platform continues to grow, less experienced physicians will likely use
the devices, potentially leading to more injury and an increased risk of product liability claims. The use or misuse of our Lumivascular platform products has
in  the  past  resulted,  and  may  in  the  future  result,  in  complications,  including  damage  to  the  treated  artery,  infection,  internal  bleeding,  and  limb  loss,
potentially leading to product liability claims. Our Lumivascular platform products are contraindicated for use in the carotid, cerebral, iliac, or renal arteries.
Our sales force does not promote the use of our products for off-label indications, and our U.S. instructions for use specify that our Lumivascular platform
products  are  not  intended  for  use  in  the  carotid,  cerebral,  coronary,  iliac  or  renal  arteries.  However,  we  cannot  prevent  a  physician  from  using  our
Lumivascular platform products for these off-label applications. The application of our Lumivascular platform products to coronary arteries, as opposed to
peripheral arteries, is more likely to result in complications that have serious consequences. For example, if excised plaque were not captured properly in our
device, it could be carried by the bloodstream to a narrower location, blocking a coronary artery, leading to a heart attack, or blocking an artery to the brain,
leading to a stroke. If our Lumivascular platform products are defectively designed, manufactured or labeled, contain defective components or are misused, we
may  become  subject  to  costly  litigation  initiated  by  our  customers  or  their  patients.  Product  liability  claims  are  especially  prevalent  in  the  medical  device
industry  and  could  harm  our  reputation,  divert  management’s  attention  from  our  core  business,  be  expensive  to  defend  and  may  result  in  sizable  damage
awards against us. Although we maintain product liability insurance, the amount or breadth of our coverage may not be adequate for the claims that are made
against us.

The  expense  and  potential  unavailability  of  insurance  coverage  for  liabilities  resulting  from  our  products  could  harm  us  and  our  ability  to  sell  our
Lumivascular platform products.

We  may  not  have  sufficient  insurance  coverage  for  future  product  liability  claims.  We  may  not  be  able  to  obtain  insurance  in  amounts  or  scope
sufficient to provide us with adequate coverage against all potential liabilities. Any product liability claims brought against us, with or without merit, could
increase our product liability insurance rates or prevent us from securing continuing coverage, harm our reputation in the industry, significantly increase our
expenses, and reduce product sales. Product liability claims in excess of our insurance coverage would be paid out of cash reserves, harming our financial
condition and operating results.

Some of our customers and prospective customers may have difficulty in procuring or maintaining liability insurance to cover their operations and
use of our Lumivascular platform products. Medical malpractice carriers are also withdrawing coverage in certain states or substantially increasing premiums.
If  this  trend  continues  or  worsens,  our  customers  may  discontinue  using  our  Lumivascular  platform  products  and  potential  customers  may  opt  against
purchasing our Lumivascular platform products due to the cost or inability to procure insurance coverage.

Risks Related to Our Organizational Structure

Our stock price may be volatile, and purchasers of our common stock could incur substantial losses.

Our  stock  price  has  fluctuated  significantly  since  our  IPO  and  is  likely  to  continue  to  fluctuate  substantially.  As  a  result  of  this  price  fluctuation,
investors may experience losses on their investments in our stock. In addition, the development stage of our operations may make it difficult for investors to
evaluate the success of our business to date and to assess our future viability. The market price for our common stock may be influenced by many factors,
including:

● sales of stock by our existing stockholders, including our affiliates;

● market acceptance of our Lumivascular platform and products;

● the results of our clinical trials;

● changes  in  analysts’  estimates,  investors’  perceptions,  recommendations  by  securities  analysts  or  our  failure  to  achieve  analysts’  and  our  own

estimates;

● the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

● actual or anticipated fluctuations in our financial condition and operating results;

● quarterly variations in our or our competitors’ results of operations;

41

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● general market conditions and other factors unrelated to our operating performance or the operating performance of our competitors;

● changes in operating performance and stock market valuations of other technology companies generally, or those in the medical device industry in

particular;

● the loss of key personnel, including changes in our board of directors and management;

● legislation or regulation of our business;

● lawsuits threatened or filed against us;

● the announcement or approvals of new products or product enhancements by us or our competitors;

● announcements related to patents issued to us or our competitors and to litigation; and

● developments in our industry.

From time to time, our affiliates may sell stock for reasons due to their personal financial circumstances. These sales may be interpreted by other
stockholders as an indication of our performance and result in subsequent sales of our stock that have the effect of creating downward pressure on the market
price of our common stock. In addition, the stock prices of many companies in the medical device industry have experienced wide fluctuations that have often
been unrelated to the operating performance of those companies.

The market price and trading volume of our common stock has been volatile over the past year, and it may continue to be volatile. Over the past year,
our common stock has traded as low as $9.00 and as high as $46.00 per share. We cannot predict the price at which our common stock will trade in the future
and it may decline. The price at which our common stock trades may fluctuate significantly and may be influenced by many factors, including our financial
results;  developments  generally  affecting  our  industry;  general  economic,  industry  and  market  conditions;  the  depth  and  liquidity  of  the  market  for  our
common  stock;  investor  perceptions  of  our  business;  reports  by  industry  analysts;  announcements  by  other  market  participants,  including,  among  others,
investors,  our  competitors,  and  our  customers;  regulatory  action  affecting  our  business;  and  the  impact  of  other  “Risk  Factors”  discussed  in  this  Annual
Report. In addition, changes in the trading price of our common stock may be inconsistent with our operating results and outlook. The volatility of the market
price of our common stock may adversely affect investors’ ability to purchase or sell shares of our common stock.

We may fail to meet our publicly announced guidance or other expectations about our business and future operating results, which would cause our stock
price to decline.

We have provided in the past and may provide guidance in the future about our business and future operating results. In developing this guidance, our
management  must  make  certain  assumptions  and  judgments  about  our  future  performance,  including  projected  revenues  and  the  timing  of  regulatory
approvals. Furthermore, analysts and investors may develop and publish their own projections of our business, which may form a consensus about our future
performance. Our business results may vary significantly from such guidance or that consensus due to a number of factors, many of which are outside of our
control, and which could adversely affect our operations and operating results. Furthermore, if we make downward revisions of our previously announced
guidance,  or  if  our  publicly  announced  guidance  of  future  operating  results  fails  to  meet  expectations  of  securities  analysts,  investors  or  other  interested
parties, the price of our common stock would decline. 

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, our share price and
trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our
business, our market and our competitors. We do not have any control over these analysts. The analysts who previously published research reports on our
stock following our IPO have discontinued coverage. Although one new analyst initiated coverage of our business in September 2019, if additional analysts do
not begin regularly publishing reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

42

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Sales of a substantial number of shares of our common stock in the public market, including by our existing stockholders, could cause our stock price to
fall.

Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, could depress the
market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the
effect that these sales and others may have on the prevailing market price of our common stock.

We will need to raise additional funds through future equity or debt financings to meet our operational needs and capital requirements for product
development, clinical trials and commercialization. We can provide no assurance that we will be successful in raising funds pursuant to additional equity or
debt  financings  or  that  such  funds  will  be  raised  at  prices  that  do  not  create  substantial  dilution  for  our  existing  stockholders.  Given  our  stock  price,  any
financing that we undertake in the future could cause substantial dilution to our existing stockholders.

On March 7, 2019, we filed a universal shelf registration statement (the “Shelf Registration Statement”) to offer up to $50.0 million of our securities,
which expires on March 29, 2022. We have established, and may in the future establish, “at-the-market” programs pursuant to which we may offer and sell
shares of our common stock pursuant to the Shelf Registration Statement. Due to the SEC’s “baby shelf rules,” which prohibit companies with a public float of
less  than  $75  million  from  issuing  securities  under  a  shelf  registration  statement  in  excess  of  one-third  of  such  company’s  public  float  in  a  twelve-month
period, we are limited in our ability to use the Shelf Registration Statement.

Our directors and employees may sell our stock through 10b5-1 trading plans or in the market during open windows under our insider trading policy
without  such  plans  in  place.  Sales  of  our  common  stock  by  our  directors  and  employees  could  be  perceived  negatively  by  investors  or  cause  downward
pressure on our common stock and cause a reduction in the price of our common stock as a result. We have also registered shares of our common stock that we
may issue under our employee equity incentive plans. These shares will be able to be sold freely in the public market upon issuance.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain executive
management and qualified board members.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the
Sarbanes-Oxley  Act,  the  Dodd-Frank  Act,  the  listing  requirements  of  Nasdaq  and  other  applicable  securities  laws,  rules  and  regulations.  Compliance  with
these  laws,  rules  and  regulations  have  increased  our  legal  and  financial  compliance  costs  and  will  make  some  activities  more  difficult,  time-consuming  or
costly and increase demand on our systems and resources, particularly after we are no longer an “emerging growth company.” The Exchange Act requires,
among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires,
among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if
required,  improve  our  disclosure  controls  and  procedures  and  internal  control  over  financial  reporting  to  meet  this  standard,  significant  resources  and
management  oversight  may  be  required.  Our  management  and  other  personnel  now  need  to  devote  a  substantial  amount  of  time  to  these  compliance
initiatives. As a result, management’s attention may be diverted from other business concerns and our costs and expenses will increase, which could harm our
business and operating results. We may need to hire more employees in the future or engage outside consultants to comply with these requirements, which will
increase our costs and expenses.

In  addition,  changing  laws,  regulations  and  standards  relating  to  corporate  governance  and  public  disclosure  are  creating  uncertainty  for  public
companies,  increasing  legal  and  financial  compliance  costs  and  making  some  activities  more  time  consuming.  These  laws,  regulations  and  standards  are
subject to varying interpretations, in many cases due to their lack of specificity and, as a result, their application in practice may evolve over time as new
guidance  is  provided  by  regulatory  and  governing  bodies.  This  could  result  in  continuing  uncertainty  regarding  compliance  matters  and  higher  costs
necessitated  by  ongoing  revisions  to  disclosure  and  governance  practices.  We  intend  to  invest  resources  to  comply  with  evolving  laws,  regulations  and
standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-
generating  activities  to  compliance  activities.  If  our  efforts  to  comply  with  new  laws,  regulations  and  standards  differ  from  the  activities  intended  by
regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us and
our business may be harmed.

43

 
 
 
 
 
 
 
 
 
 
We will incur additional compensation costs in the event that we decide to pay our executive officers cash compensation closer to that of executive
officers of other public medical device companies, which would increase our general and administrative expense and could harm our profitability. Any future
equity awards will also increase our compensation expense. We also expect that being a public company and compliance with applicable rules and regulations
will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially
higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified executive officers and members of our
board of directors, particularly to serve on our audit committee and compensation committee.

As a result of disclosure of information in this Annual Report on Form 10-K and in other filings required of a public company, our business and
financial condition will become more visible, which could be advantageous to our competitors and clients and could result in threatened or actual litigation,
including by competitors and other third parties. If such claims are successful, our business and operating results could be harmed, and even if the claims are
resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and harm our business
and operating results.

Nasdaq may delist our securities from its exchange, which could harm our business and limit our stockholders’ liquidity.

Our common stock is currently listed on the Nasdaq Capital Market (“Nasdaq”), which has qualitative and quantitative listing criteria. However, we
cannot assure you that our common stock will continue to be listed on Nasdaq in the future. In order to continue listing our common stock on Nasdaq, we must
maintain certain financial, distribution and stock price levels. Generally, we must maintain a minimum amount in stockholders’ equity, a minimum number of
holders of our common stock and a minimum bid price.

On  September  22,  2021,  we  received  a  letter  from  Nasdaq’s  Listing  Qualifications  Department  notifying  us  that  we  were  not  in  compliance  with
Nasdaq Listing Rule 5550(a)(2), as the minimum bid price for our listed securities was less than $1 for the previous 30 consecutive business days. We had a
period of 180 calendar days, or until March 21, 2022, to regain compliance with the rule referred to in this paragraph. To regain compliance, the bid price of
our common stock must close at $1 or more for a minimum of ten consecutive business days. The notice has no present impact on the listing of our securities
on Nasdaq. On March 14, 2022, we effected a 1-for-20 reverse stock split of our outstanding shares of common stock. However, there is no guarantee that
such reverse stock split will result in the bid price of our common stock closing at $1 or more for the required ten consecutive business days.

We have not yet regained compliance with the Minimum Bid Price Requirement. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have

provided written notice to Nasdaq requesting an additional 180 calendar days to cure the deficiency on March 17, 2022, but have not yet received a response.

In the event that we do not regain compliance with the Nasdaq Listing Rules prior to the expiration of the compliance period, we will receive written
notification that our securities are subject to delisting. At that time, we may appeal the delisting determination to a hearings panel pursuant to the procedures
set forth in the applicable Nasdaq Listing Rules. We intend to actively monitor our bid price and will consider available options to resolve the deficiency and
regain compliance with the Nasdaq Listing Rules, including considering whether to conduct a reverse stock split.

If Nasdaq delists our common stock from trading on its exchange and we are not able to list our securities on another national securities exchange, we
expect our securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:

● a limited availability of market quotations for our securities;

● reduced liquidity for our securities;

● a determination that our common stock is a “penny stock” which will require brokers trading in our common stock to adhere to more stringent rules

and possibly result in a reduced level of trading activity in the secondary trading market for our securities;

● a limited amount of news and analyst coverage; and

● a decreased ability to issue additional securities or obtain additional financing in the future.

The  National  Securities  Markets  Improvement  Act  of  1996,  which  is  a  federal  statute,  prevents  or  preempts  the  states  from  regulating  the  sale  of
certain securities, which are referred to as “covered securities.” If our common stock continues to be listed on NASDAQ, our common stock will be a covered
security. Although the states are preempted from regulating the sale of our securities, the federal statute does allow the states to investigate companies if there
is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case.

Anti-takeover provisions in our amended and restated certificate of incorporation and bylaws and Delaware law could discourage a takeover.

Our amended and restated certificate of incorporation and bylaws contain provisions that might enable our management to resist a takeover. These

provisions include:

● a classified board of directors;

● advance notice requirements applicable to stockholders for matters to be brought before a meeting of stockholders and requirements as to the form

and content of a stockholder’s notice;

● a supermajority stockholder vote requirement for amending certain provisions of our amended and restated certificate of incorporation and bylaws;

● the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer;

● allowing stockholders to remove directors only for cause;

● a requirement that the authorized number of directors may be changed only by resolution of the board of directors;

● allowing all vacancies, including newly created directorships, to be filled by the affirmative vote of a majority of directors then in office, even if less

than a quorum, except as otherwise required by law;

● a requirement that our stockholders may only take action at annual or special meetings of our stockholders and not by written consent;

● limiting the forum for certain litigation against us to Delaware; and

● limiting the persons that can call special meetings of our stockholders to our board of directors, the chairperson of our board of directors, the chief

executive officer or the president (in the absence of a chief executive officer).

These  provisions  might  discourage,  delay  or  prevent  a  change  in  control  of  our  company  or  a  change  in  our  management.  The  existence  of  these
provisions could adversely affect the voting power of holders of common stock and limit the price that investors might be willing to pay in the future for
shares of our common stock. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General
Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested”
stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder.

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the sole and exclusive forum
for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes
with us or our directors, officers or employees.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of
Chancery of the State of Delaware is the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a
claim of breach of fiduciary duty owed by any of our directors, officers or other employees to us or to our stockholders, (iii) any action asserting a claim
arising pursuant to the Delaware General Corporation Law or our certificate of incorporation or bylaws (iv) any action to interpret, apply, enforce or determine
the validity of our certificate of incorporation or bylaws, or (v) any action asserting a claim governed by the internal affairs doctrine. This exclusive forum
provision would not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other claim for which the
federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates
exclusive  federal  jurisdiction  over  all  suits  brought  to  enforce  any  duty  or  liability  created  by  the  Exchange  Act  or  the  rules  and  regulations  thereunder.
Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability
created by the Securities Act or the rules and regulations thereunder.

This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our
directors, officers or employees, which may discourage such lawsuits against us and our directors, officers or employees. If a court were to find the choice of
forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with
resolving  such  action  in  other  jurisdictions,  which  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of  operations  and
prospects.

We have not paid cash dividends in the past and do not expect to pay cash dividends in the future, and any return on investment may be limited to the
value of our stock.

We have never paid cash dividends and do not anticipate paying cash dividends in the foreseeable future. The payment of dividends will depend on
our earnings, capital requirements, financial condition, prospects and other factors our board of directors may deem relevant. In addition, our Loan Agreement
with CRG prohibits us from, among other things, paying any dividends or making any other distribution or payment on account of our common stock. The
terms of our Series A preferred stock, Series B preferred stock and Series D preferred stock provide that we may not pay dividends on our common stock
without concurrently declaring dividends on each. If we do not pay dividends, our stock may be less valuable because a return on your investment will only
occur  if  you  sell  our  common  stock  after  our  stock  price  appreciates.  For  more  information  on  restrictions  governing  our  ability  to  pay  dividends,  see  the
section titled “Dividend Policy” below.

CRG has the ability to exert significant control over matters pursuant to the protective provisions therein as well as the covenants and other restrictions in
the Loan Agreement.

Even though Series A preferred stock is non-voting stock, our governing documents, as amended, have protective provisions that will require CRG to
consent to certain significant Company events. For example, CRG’s consent would be necessary to create additional shares of Series A preferred stock, amend
our organizational documents, or approve any merger, sale of assets, or other major corporate transaction. This consent requirement could delay or prevent any
acquisition of our company on terms that other stockholders may desire, and may adversely affect the market price of our common stock.

The Series A preferred stock and Series D preferred stock have a liquidation preference senior to our common stock and Series B preferred stock.

Series  A  preferred  stock  and  Series  D  preferred  stock  have  a  liquidation  preference  that  gets  paid  prior  to  any  payment  on  our  common  stock
(including shares issuable upon the exercise of our outstanding warrants) and Series B preferred stock. As a result, if we were to dissolve, liquidate, merge
with another company or sell our assets, the holders of our Series A preferred stock would have the right to receive up to approximately $56.4 million as of
December 31, 2021, plus any unpaid dividends, and, after the payment of the liquidation preference to the holders of the Series A preferred stock before any
amount  is  paid  to  the  holders  of  our  Series  B  preferred  stock  or  common  stock  or  pursuant  to  the  redemption  rights  in  the  warrants  for  fundamental
transactions. The holders of our Series D preferred stock would also have the right to receive up to $0.01 per share of Series D preferred stock, subject to the
liquidation preference of the Series A preferred stock. The payment of the liquidation preferences could result in common stockholders, Series B preferred
stockholders and warrant holders not receiving any consideration if we were to liquidate, dissolve or wind up, either voluntarily or involuntarily. In January
2019, December 2019, December 2020 and December 2021, 2,945, 3,580, 3,866 and 4,175 additional shares of Series A preferred stock, respectively, were
issued to CRG as payment of dividends accrued through December 31, 2021.

46

 
 
 
 
 
 
 
 
 
 
 
The existence of the liquidation preferences may reduce the value of our common stock, make it harder for us to sell shares of common stock in

offerings in the future, or prevent or delay a change of control.

We depend on our board of directors and the loss of one or more or our board members or an inability to attract and retain highly qualified members
could harm our business.

Our success largely depends upon the continued services and involvement of the members of our board of directors and the loss of one or more of our
directors could adversely affect us. Additionally, changes in the composition of our board resulting from the addition or departure of members could disrupt
our business.

We  must  attract  and  retain  highly  qualified  board  members.  Competition  for  these  individuals  can  be  intense.  We  have,  from  time  to  time,
experienced, and we may experience in the future, difficulty in adding and retaining members of our board with appropriate qualifications. In addition, some
states and other regulatory authorities, including Nasdaq, have adopted board diversity requirements, which mandate that companies have a minimum number
of directors who meet specified diversity criteria, or otherwise require that companies disclose board diversity information. If we are unable to attract and
retain qualified board members who meet such diversity criteria, we will be unable to comply with such requirements and could face enforcement or other
regulatory actions.

ITEM 2.    PROPERTIES

The Company’s operating lease obligations primarily consist of leased office, laboratory, and manufacturing space under a non-cancelable operating
lease  located  in  Redwood  City,  California.  In  addition  to  the  minimum  future  lease  commitments  presented  below,  the  lease  requires  the  Company  to  pay
property taxes, insurance, maintenance, and repair costs. The lease includes a rent holiday concession and escalation clauses for increased rent over the lease
term. Rent expense is recognized in accordance with the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 842,
Leases, using the straight-line method over the term of the lease. The Company records deferred rent calculated as the difference between rent expense and the
cash rental payments.

The lease will expire on November 30, 2024. The Company is obligated to pay approximately $5.8 million in base rent payments through November

2024, beginning on December 1, 2019. The weighted average remaining lease term as of December 31, 2021 is 2.9 years.

We believe that our current facilities are adequate for our current and anticipated future needs through at least 2022.

ITEM 3.    LEGAL PROCEEDINGS

We  are  not  involved  in  any  pending  legal  proceedings  that  we  believe  could  have  a  material  adverse  effect  on  our  financial  condition,  results  of
operations  or  cash  flows.  From  time  to  time  we  may  be  involved  in  legal  proceedings  or  investigations,  which  could  harm  our  reputation,  business  and
financial condition and divert the attention of our management from the operation of our business.

ITEM  5.        MARKET  FOR  REGISTRANT’S  COMMON  EQUITY,  RELATED  STOCKHOLDER  MATTERS  AND  ISSUER  PURCHASES  OF
EQUITY SECURITIES

Our common stock began trading on the Nasdaq Global Market on January 30, 2015 and was transferred to the Nasdaq Capital Market on January 19, 2018,
where it trades under the symbol “AVGR”.

HOLDERS OF RECORD

As of March 18, 2022, there were 5,428,770 shares of our common stock held by 123 holders of record of our common stock. The actual number of
stockholders is greater than this number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name by
brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

DIVIDEND POLICY

Our  Series  A  preferred  stock  carries  an  8%  cumulative  dividend,  which  accumulates  and  is  compounded  annually.  This  cumulative  dividend  is
payable in arrears on December 31 of each year, commencing with December 31, 2018, and at our option is payable in additional shares of Series A preferred
stock. Additionally, the terms of our Series A preferred stock and Series B preferred stock provide that we may not declare dividends on the common stock
without concurrently declaring dividends on such series of preferred stock in an amount equal to that payable had they been converted to common stock prior
to the dividend. We have issued a total of 14,566 shares of Series A preferred stock to pay the preferred dividend to the holder of Series A preferred stock
through December 31, 2021. Other than the preferred dividend on Series A preferred stock, we have never declared or paid any cash dividends on any of our
capital stock. Except with respect to the Series A preferred stock’s cumulative dividend, we do not anticipate paying any dividends in the foreseeable future
and currently intend to retain all available funds and any future earnings for use in the operation of our business and to finance the growth and development of
our business.

Future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors and will depend on then
existing conditions, including our operating results, financial condition, contractual restrictions, capital requirements, business prospects and other factors our
board of directors may deem relevant. In addition, our Loan Agreement with CRG prohibits us from paying any dividends or making any other distribution or
payment on account of our common stock.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and
related notes included elsewhere in this Annual Report on Form 10-K. This discussion and other parts of this Annual Report on Form 10-K contain forward-
looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions, that are based on the beliefs of
our management, as well as assumptions made by, and information currently available to, our management. Our actual results could differ materially from
those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed
in the section of this Annual Report on Form 10-K entitled “Risk factors.”

Overview

We are a commercial-stage medical device company that designs, manufactures and sells real-time image-guided, minimally invasive catheter-based
systems that are used by physicians to treat patients with peripheral artery disease, or PAD. Patients with PAD have a build-up of plaque in the arteries that
supply blood to areas away from the heart, particularly the pelvis and legs. Our mission is to significantly improve the treatment of vascular disease through
the introduction of products based on our Lumivascular platform, the only intravascular real-time image-guided system available in this market.

We  design,  manufacture,  and  sell  a  suite  of  products  in  the  United  States  and  select  international  markets.  We  are  located  in  Redwood  City,
California. Our current Lumivascular platform consists of products including our Lightbox real-time imaging console, the Ocelot family of catheters, which
are  image-guided  catheters  designed  to  allow  physicians  to  penetrate  a  total  blockage  in  an  artery,  known  as  a  chronic  total  occlusion,  or  CTO,  and  the
Pantheris family of catheters, our image-guided atherectomy family of catheters which is designed to allow physicians to precisely remove arterial plaque in
PAD patients.

We received CE Marking for our original Ocelot product in September 2011 and received from the U.S. Food and Drug Administration, or FDA,
510(k)  clearance  in  November  2012.  We  received  510(k)  clearance  from  the  FDA  for  commercialization  of  Pantheris  in  October  2015.  We  received  an
additional 510(k) clearance for an enhanced version of Pantheris in March 2016 and commenced sales of Pantheris in the United States and select European
countries promptly thereafter. In May 2018, we received 510(k) clearance from the FDA for our current next-generation version of Pantheris. In April 2019,
we  received  510(k)  clearance  from  the  FDA  for  our  Pantheris  SV,  a  version  of  Pantheris  targeting  smaller  vessels,  and  commenced  sales  in  July  2019.  In
September 2020, we received 510(k) clearance of Tigereye, a next-generation CTO crossing system utilizing Avinger’s proprietary image-guided technology
platform.  Tigereye  is  a  product  line  extension  of  Avinger’s  Ocelot  family  of  image-guided  CTO  crossing  catheters.  In  January  2022,  we  received  510(k)
clearance  from  the  FDA  for  our  Lightbox  3  imaging  console,  a  version  of  our  Lightbox  presenting  significant  reductions  in  size,  weight  and  cost  in
comparison to the incumbent version.

Current treatments for PAD, including bypass surgery, can be costly and may result in complications, high levels of post-surgery pain, and lengthy
hospital stays and recovery times. Minimally invasive, or endovascular, treatments for PAD include stenting, angioplasty, and atherectomy, which is the use of
a catheter-based device for the removal of plaque. These treatments all have limitations in their safety or efficacy profiles and frequently result in recurrence
of the disease, also known as restenosis. We believe one of the main contributing factors to high restenosis rates for PAD patients treated with endovascular
technologies  is  the  amount  of  vascular  injury  that  occurs  during  an  intervention.  Specifically,  these  treatments  often  disrupt  the  membrane  between  the
outermost layers of the artery, which is referred to as the external elastic lamina, or EEL.

We  believe  our  Lumivascular  platform  is  the  only  technology  that  offers  real-time  visualization  of  the  inside  of  the  artery  during  PAD  treatment
through  the  use  of  optical  coherence  tomography,  or  OCT,  a  high  resolution,  light-based,  radiation-free  imaging  technology.  Our  Lumivascular  platform
provides physicians with real-time OCT images from the inside of an artery, and we believe Ocelot and Pantheris are the first products to offer intravascular
visualization  during  CTO  crossing  and  atherectomy,  respectively.  We  believe  this  approach  will  significantly  improve  patient  outcomes  by  providing
physicians with a clearer picture of the artery using radiation-free image guidance during treatment, enabling them to better differentiate between plaque and
healthy arterial structures. Our Lumivascular platform is designed to improve patient safety by enabling physicians to direct treatment towards the plaque,
while avoiding damage to healthy portions of the artery.

50

 
 
 
 
 
 
 
 
 
 
During  the  first  quarter  of  2015,  we  completed  enrollment  of  patients  in  VISION,  a  clinical  trial  designed  to  support  our  August  2015  510(k)
submission to the FDA for our Pantheris atherectomy device. VISION was designed to evaluate the safety and efficacy of Pantheris to perform atherectomy
using intravascular imaging and successfully achieved all primary and secondary safety and efficacy endpoints. We believe the data from VISION allows us to
demonstrate that avoiding damage to healthy arterial structures, and in particular disruption of the external elastic lamina, which is the membrane between the
outermost layers of the artery, reduces the likelihood of restenosis, or re-narrowing, of the diseased artery. Although the original VISION study protocol was
not designed to follow patients beyond six months, we worked with 18 of the VISION sites to re-solicit consent from previous clinical trial patients in order
for them to evaluate patient outcomes through 12 and 24 months following initial treatment. Data collection for the remaining patients from participating sites
was completed in May 2017, and we released the final 12- and 24-month results for a total of 89 patients in July 2017.

During the fourth quarter of 2017, we began enrolling patients in INSIGHT, a clinical trial designed to support a submission to the FDA to expand
the indication for our Pantheris atherectomy device to include in-stent restenosis. Patient enrollment began in October 2017 and was completed in July 2021.
Patient outcomes are being evaluated at thirty days, six months and one year following treatment. In November 2021, we received 510(k) clearance from the
FDA for a new clinical indication for treating in-stent restenosis with Pantheris using the data collected and analyzed from INSIGHT. We expect this will
expand our addressable market for Pantheris to include a high-incidence disease state for which there are few available indicated treatment options.

We  focus  our  direct  sales  force,  marketing  efforts  and  promotional  activities  on  interventional  cardiologists,  vascular  surgeons  and  interventional
radiologists. We also work on developing strong relationships with physicians and hospitals that we have identified as key opinion leaders. Although our sales
and marketing efforts are directed at these physicians because they are the primary users of our technology, we consider the hospitals and medical centers
where  the  procedure  is  performed  to  be  our  customers,  as  they  typically  are  responsible  for  purchasing  our  products.  We  are  designing  additional  future
products  to  be  compatible  with  our  Lumivascular  platform,  which  we  expect  to  enhance  the  value  proposition  for  hospitals  to  invest  in  our  technology.
Pantheris qualifies for existing reimbursement codes currently utilized by other atherectomy products, further facilitating adoption of our products.

We have assembled a team with extensive medical device development and commercialization experience in both start-up and large, multi-national
medical device companies. We assemble all of our products at our manufacturing facility but certain critical processes, such as coating and sterilization, are
performed by outside vendors. We expect our current manufacturing facility in California, will be sufficient through at least 2022. We generated revenues of
$9.1 million in 2019 and $8.8 million in 2020 and $10.1 million in 2021. The decline in revenue in 2020 was primarily due to the adverse effects of COVID-
19 on our customers as hospitals deferred elective procedures.

Recent Developments

COVID-19 Update

As a result of the effects of the COVID-19 pandemic, we experienced a significant decline in sales in the second quarter of 2020, particularly as
individuals, as well as hospitals and other medical providers, deferred elective procedures in response to COVID-19. Starting in the third quarter of 2020, we
experienced a rebound of sales as practitioners began to once again perform elective procedures. At present, a majority of jurisdictions have eased or are in the
process of lifting restrictions on performing elective procedures, we cannot be certain that other jurisdictions in the United States will do so in the near future.
Some jurisdictions have experienced and continue to experience a resurgence in COVID-19 cases, which has prompted certain hospitals and other medical
providers  in  such  areas  to  again  defer  elective  procedures  or  further  prolong  or  reinstate  existing  restrictions  on  such  procedures.  If  other  jurisdictions
experience a resurgence in COVID-19 cases, these jurisdictions may also prolong restrictions on elective procedures. This situation has created a significant
amount of volatility in the medical industry which makes future developments and results difficult to predict. While sales during 2021 increased in comparison
to 2020, we believe COVID-19 has had and will continue to have an adverse effect on our ability to generate sales due to the fluctuating and unpredictable
levels of capacity medical providers have to perform procedures that require the use of our products. Consequently, it is unclear whether any reduction in sales
from  levels  experienced  prior  to  COVID-19  is  temporary  and  whether  such  sales  may  be  recoverable  in  the  future.  In  addition,  we  have  experienced
disruptions  in  our  manufacturing  and  supply  chain,  as  well  as  delays  in  site  initiation  and  patient  enrollment  for  our  clinical  studies.  If  we  are  unable  to
successfully complete these or other clinical studies, our business and results of operations could be harmed.

51

 
 
 
 
 
 
 
 
 
During  2020,  we  undertook  actions  to  manage  our  available  cash  and  other  resources  to  help  mitigate  the  effects  of  COVID-19  on  our  business,
including by adjusting production to match demand for our products and reducing discretionary costs. For example, during the second quarter of 2020, we
reduced base salaries for all of our non-manufacturing employees by 20% and reduction of hours worked by our manufacturing workers by 20%. Salaries and
hours worked returned to prior levels starting in the third quarter of 2020. However, the COVID-19 pandemic and responses thereto have resulted in reduced
consumer  and  investor  confidence,  instability  in  the  credit  and  financial  markets,  volatile  corporate  profits,  and  reduced  business  and  consumer  spending,
which could increase the cost of capital and/or limit the availability of capital to us in the future. These and other factors could adversely affect our ability to
effectively manage our available cash and other resources.

Nasdaq Delisting Notice

On September 22, 2021, we received a letter from the Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market, LLC (“Nasdaq”)
notifying  the  Company  that  the  Company  was  not  in  compliance  with  Nasdaq  Listing  Rule  5550(a)(2)  (the  “Minimum  Bid  Price  Requirement”),  as  the
minimum bid price for the Company’s listed securities was less than $1.00 for the previous 30 consecutive business days. We had a period of 180 calendar
days, or until March 21, 2022, to regain compliance with the rule referred to in this paragraph. To regain compliance, the bid price of our common stock must
close at $1 or more for a minimum of ten consecutive business days. The notice has no present impact on the listing of our securities on Nasdaq. On March 14,
2022, we effected a 1-for-20 reverse stock split of our outstanding shares of common stock. However, there is no guarantee that such reverse stock split will
result in the bid price of our common stock closing at $1 or more for the required ten consecutive business days.

We  have  not  yet  regained  compliance  with  the  Minimum  Bid  Price  Requirement.  In  accordance  with  Nasdaq  Listing  Rule  5810(c)(3)(A),  we

provided written notice to Nasdaq requesting an additional 180 calendar days to cure the deficiency on March 17, 2022, but have not yet received a response.

In the event that we do not regain compliance with the Nasdaq Listing Rules prior to the expiration of the compliance period, we will receive written
notification that its securities are subject to delisting. At that time, we may appeal the delisting determination to a hearings panel pursuant to the procedures set
forth in the applicable Nasdaq Listing Rules. We intend to actively monitor the bid price of our common stock and will consider available options to resolve
the deficiency and regain compliance with the Nasdaq Listing Rules, including conducting a reverse stock split.

Global Supply Chain

We  are  closely  monitoring  the  impacts  of  COVID-19  and  general  economic  conditions  on  global  supply  chain,  manufacturing,  and  logistics
operations. As inflationary pressures increase, we anticipate that our production and operating costs may similarly increase, including costs and availability of
materials  and  labor.  In  addition,  COVID-19  and  other  events,  including  port  closures  or  labor  shortages,  have  resulted  in  manufacturing  and  shipping
constraints generally. While we have had sufficient inventory on-hand to meet our production requirements and customer demand, we have experienced some
constraints with respect to the availability of certain materials and extended lead times from certain key suppliers. We have also experienced some delays in
shipping products to our customers. Any significant delay or interruption in our supply chain could impair our ability to meet the demands of our customers
and could harm our business.

Reverse Stock Split

On  March  11,  2022,  our  Board  of  Directors  approved  an  amendment  to  our  amended  and  restated  certificate  of  incorporation  to  effect  a  1-for-20
reverse stock split of our issued and outstanding common stock. The reverse stock split became effective on March 14, 2022. The par value of the common
stock and preferred stock was not adjusted as a result of the reverse stock split. All common stock, stock options, and restricted stock units, and per share
amounts in the financial statements have been retroactively adjusted for all periods presented to give effect to the reverse stock splits.

Financing

During the years ended December 31, 2021 and 2020, our net loss and comprehensive loss was $17.4 million and $19.0 million, respectively. We
have not been profitable since inception, and as of December 31, 2021, our accumulated deficit was $384.8 million. Since inception, we have financed our
operations primarily through private and public placements of our preferred and common securities and, to a lesser extent, debt financing arrangements.

In  September  2015,  we  entered  into  a  Term  Loan  Agreement,  or  Loan  Agreement,  with  CRG  Partners  III  L.P.  and  certain  of  its  affiliated  funds,
collectively CRG, under which we were able to borrow up to $50.0 million on or before March 29, 2017, subject to certain terms and conditions. We borrowed
$30.0 million on September 22, 2015 and an additional $10.0 million on June 15, 2016 under the Loan Agreement. Contemporaneously with the execution of
the  Loan  Agreement,  we  entered  into  a  Securities  Purchase  Agreement  with  CRG,  pursuant  to  which  CRG  purchased  44  shares  of  our  common  stock  on
September 22, 2015 at a price of $111,928 per share, which represents the 10-day average of closing prices of our common stock ending on September 21,
2015. Pursuant to the Securities Purchase Agreement, we filed a registration statement covering the resale of the shares sold to CRG and must comply with
certain affirmative covenants during the time that such registration statement remains in effect.

On February 14, 2018, we entered into a Series A preferred stock Purchase Agreement (the “Series A Purchase Agreement”) with CRG, pursuant to
which it agreed to convert $38.0 million of the outstanding principal amount of its senior secured term loan (plus the back-end fee and prepayment premium
applicable thereto) under the Loan Agreement into a newly authorized Series A preferred stock. As discussed in the section of this report titled “Dividend
Policy,”  the  holders  of  Series A  preferred  stock  are  entitled  to  receive  annual  accruing  dividends  at  a  rate  of  8%,  payable  in  additional  shares  of  Series A
preferred  stock  or  cash,  at  our  option.  The  shares  of  Series A  preferred  stock  have  no  voting  rights  and  rank  senior  to  all  other  classes  and  series  of  the
Company’s equity in terms of repayment and certain other rights.

We have entered into several amendments to the Term Loan Agreement (the “Amendments”) with CRG since September 2015, the most recent of
which,  was  entered  into  on  January  22,  2021.  The  Amendments,  among  other  things:  (1)  extended  the  interest-only  period  through  December  31,  2023;
(2) extended the period during which we may elect to pay a portion of interest in payment-in-kind, or PIK, interest payments through December 31, 2023 so
long as no default has occurred and is continuing; (3) permitted us to make our entire interest payments in PIK interest payments for through December 31,
2023  so  long  as  no  default  has  occurred  and  is  continuing;  (4)  extended  the  maturity  date  to  December  31,  2025;  (5)  reduced  the  minimum  liquidity
requirement to $3.5 million at all times; (6) eliminated the minimum revenue covenant for 2018, 2019 and 2020; (7) reduced the minimum revenue covenant
to $8 million for 2021, $10 million for 2022; (8) added minimum revenue covenants for of $12 million for 2023, $14.5 million for 2024 and $17 million for
2025; (9) changed the date under the on-going stand-alone representation regarding no “Material Adverse Change” to December 31, 2020; (10) amended the
on-going stand-alone representation and stand-alone event of default regarding Material Adverse Change such that any adverse change in or effect upon the
revenue  of  us  and  our  subsidiaries  due  to  the  outbreak  of  COVID-19  will  not  constitute  a  Material  Adverse  Change;  and  (11)  provided  CRG  with  board
observer rights. 

Components of our Results of Operations

Revenues

All  of  our  revenues  are  currently  derived  from  sales  of  our  various  PAD  catheters  in  the  United  States  and  select  international  markets,  Lightbox
consoles, and related services. We expect our revenues to increase in 2022 due to the availability of our Tigereye product launch in late 2020 and easing of
restrictions  on  elective  procedures  due  to  the  diminishing  impact  of  COVID-19.  For  the  year  ended  December  31,  2021,  there  was  one  customer  that
represented 10% of revenues. For the year ended December 31, 2020, there were no customers that represented 10% or more of revenues.

Revenues may fluctuate from quarter to quarter due to a variety of factors including capital equipment purchasing patterns that are typically increased
towards the end of the calendar year and decreased in the first quarter. In addition, during the first quarter, our results can be harmed by adverse weather and
by resetting of annual patient healthcare insurance plan deductibles, both of which may cause patients to delay elective procedures. In the third quarter, the
number  of  elective  procedures  nationwide  is  historically  lower  than  other  quarters  throughout  the  year,  which  we  believe  is  primarily  attributable  to  the
summer vacations of physicians and their patients. Additionally, we believe COVID-19 has had and will continue to have an adverse effect on our ability to
generate sales due to the fluctuating and unpredictable levels of capacity medical providers have to perform procedures that require the use of our products.

53

 
 
 
 
 
 
 
 
 
 
 
Cost of Revenues and Gross Margin

Cost  of  revenues  consists  primarily  of  costs  related  to  manufacturing  overhead,  materials  and  direct  labor.  We  expense  all  warranty  costs  and
inventory  provisions  as  cost  of  revenues.  We  periodically  write-down  inventory  for  estimated  excess,  obsolete  and  non-sellable  inventories  based  on
assumptions about future demand, past usage, changes to manufacturing processes and overall market conditions. A significant portion of our cost of revenues
currently  consists  of  manufacturing  overhead  costs.  These  overhead  costs  include  the  cost  of  quality  assurance,  material  procurement,  inventory  control,
facilities, equipment and operations supervision and management. We expect overhead costs as a percentage of revenues to become less significant as our
production volume increases. Cost of revenues also includes depreciation expense for production equipment, depreciation and related maintenance expense for
placed Lightboxes held by customers and certain direct costs such as those incurred for shipping our products.

We calculate gross margin as gross profit divided by revenues. Our gross margin has been and will continue to be affected by a variety of factors,
primarily production volumes, manufacturing costs, product yields, headcount, charges for excess and obsolete inventories and cost-reduction strategies. We
intend to use our design, engineering and manufacturing capabilities to further advance and improve the efficiency of our manufacturing processes, which we
believe will reduce costs and increase our gross margin. In the future, we may seek to manufacture certain of our products outside the United States to further
reduce costs. Our gross margin will likely fluctuate from quarter to quarter as we continue to introduce new products and sales channels, and as we adopt new
manufacturing processes and technologies.

Research and Development Expenses

Research  and  development,  or  R&D,  expenses  consist  primarily  of  engineering,  product  development,  clinical  and  regulatory  affairs,  consulting
services, materials, depreciation and other costs associated with products and technologies in development. These expenses include employee compensation,
including  stock-based  compensation,  supplies,  materials,  quality  assurance  expenses  allocated  to  R&D  programs,  consulting,  related  travel  expenses  and
facilities expenses. Clinical expenses include clinical trial design, clinical site reimbursement, data management, travel expenses and the cost of manufacturing
products for clinical trials. We expect R&D expenses to vary over time depending on the level and timing of our new product development efforts, as well as
our clinical development, clinical trial and other related activities.

Selling, General and Administrative Expenses

Selling,  general  and  administrative,  or  SG&A,  expenses  consist  primarily  of  compensation  for  personnel,  including  stock-based  compensation,
selling and marketing functions, physician education programs, business development, finance, information technology and human resource functions. Other
SG&A expenses include commissions, training, travel expenses, educational and promotional activities, marketing initiatives, market research and analysis,
conferences and trade shows, professional services fees, including legal, audit and tax fees, insurance costs and general corporate expenses. We expect SG&A
expenses to increase as we expand our commercial efforts.

Interest Expense, net

Interest expense, net consists primarily of interest incurred on our outstanding indebtedness and non-cash interest related to the amortization of debt

discount and issuance costs associated with our various debt agreements.

Other Income, net

Other income, net primarily consists of gains and losses resulting from the remeasurement of foreign exchange transactions and other miscellaneous

income and expenses.

Revenues increased $1.4 million, or 16%, to $10.1 million during the year ended December 31, 2021. The increased revenues reflect the impact of
the commercial release of our Tigereye product in January 2021 and the rebounding of sales from COVID-19 as practitioners once again started to perform
elective surgical procedures in certain jurisdictions. As mentioned previously, we have experienced fluctuating demand resulting from uncertainties due to the
impact of COVID-19 on capacity limitations in hospitals. However, the capacity limitations experienced during the year ended December 31, 2021 were not
as  pervasive,  and  haven’t  had  as  profound  an  impact  on  revenues,  in  comparison  to  the  prior  fiscal  year.  We  anticipate  that  COVID-19  could  continue  to
impact hospital capacities, and related demand for our products, for the foreseeable future.

Cost of Revenues and Gross Margin.

Cost of revenues increased $0.6 million, or 9%, to $6.7 million during the year ended December 31, 2021. This increase was primarily attributable to
the increase in revenues. Stock-based compensation expense within cost of revenues totaled $0.1 million for each of the years ended December 31, 2021 and
2020.

Gross margin for the year ended December 31, 2021 increased to 34% compared to 30% in the prior year. The increase in gross margin was primarily
due to the rebound of revenues from the significant decline experienced during the three months ended June 30, 2020 due to COVID-19 and the economies of
scale experienced in 2021 relating to increased levels of production.

Research and Development Expenses.

R&D expenses increased $0.2 million or 4%, to $5.9 million during the year ended December 31, 2021. The increase is primarily due to increases in
compensation expense resulting from the cessation of cost reduction measures taken due to COVID-19 in the third quarter of 2020 and higher project spending
for next generation products such as Lightbox 3. Stock-based compensation expense within R&D totaled $0.3 million and $0.5 million for the years ended
December 31, 2021 and 2020, respectively. We expect R&D expense to remain flat.

Selling, General and Administrative Expenses.

SG&A  expenses  increased  $1.3  million,  or  9%,  to  $15.6  million  during  the  year  ended  December  31,  2021.  This  increase  was  primarily  due  to
increases in compensation expense resulting from the cessation of cost reduction measures taken due to COVID-19 in the third quarter of 2020 and increased
variable compensation resulting from the rebounding of sales as practitioners have once again started to perform elective surgical procedures. Stock-based
compensation expense within SG&A totaled $0.6 million and $0.9 million for the years ended December 31, 2021 and 2020, respectively.

Interest Expense, net.

Interest expense, net is comprised of interest expense net of interest income. Interest expense remained flat compared to the prior year primarily due
to the amendment of the CRG loan, pursuant to which we extended the maturity date of the loan thereby resulting in lesser interest expense in the near term.
This was partially offset by lower interest income as compared to the prior year, due to the decline in money market interest rates during the period.

Other income, net.

Other income, net primarily consists of gains and losses resulting from the remeasurement of foreign exchange transactions and other miscellaneous
income and expenses. Other income, net for the year ended December 31, 2021 increased $2.3 million in comparison to the prior year as the PPP loan was
fully forgiven resulting in a gain on extinguishment of that debt. Both periods included remeasurement gains and losses from foreign exchange transactions
which are typically a small percentage of transaction volume, usually resulting in nominal changes between periods.

Liquidity and Capital Resources

As of December 31, 2021, we had cash and cash equivalents of $19.5 million and an accumulated deficit of $384.8 million, compared to cash and
cash equivalents of $22.2 million and an accumulated deficit of $367.3 million as of December 31, 2020. We expect to incur losses for the foreseeable future.
We believe that our cash and cash equivalents of $19.5 million at December 31, 2021, together with the approximately $6.7 million net proceeds from the
January 2022 equity financing (see Equity Financings below), expected revenues, debt and financing activities and funds from operations will be sufficient to
allow us to fund our current operations through the second quarter of 2023.

To date, we have financed our operations primarily through net proceeds from the issuance of our preferred stock and debt financings, our “at-the-
market” program, our initial public offering, or IPO, our follow-on public offerings and warrant issuances. We do not know when or if our operations will
generate sufficient cash to fund our ongoing operations. Additional debt financing, if available, may involve covenants restricting our operations or our ability
to incur additional debt. Any additional debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders and
require significant debt service payments, which divert resources from other activities. Additional financing may not be available at all, or if available, may
not  be  in  amounts  or  on  terms  acceptable  to  us.  If  we  are  unable  to  obtain  additional  financing,  we  may  be  required  to  delay  the  development,
commercialization and marketing of our products and we may be required to significantly scale back our business and operations.

In addition, the COVID-19 pandemic and responses thereto have resulted in reduced consumer and investor confidence, instability in the credit and
financial markets, volatile corporate profits, restrictions on elective medical procedures, and reduced business and consumer spending, which could increase
the  cost  of  capital  and/or  limit  the  availability  of  capital  to  us.  While  we  have  taken  certain  actions  to  manage  our  available  cash  and  other  resources  to
mitigate the effects of COVID-19 on our business, there can be no assurance that such strategies will be successful in mitigating the negative impacts of the
COVID-19 pandemic on our liquidity and capital resources.

Equity Financings

On January 31, 2020, we completed a public offering of 321,429 shares of common stock at an offering price of $14.00 per share. As a result, we
received net proceeds of approximately $3.9 million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses. Due
to anti-dilution provisions, the conversion price of the outstanding shares of Series B preferred stock, which was issued in our February 2018 offering, was
reduced to $14.00 per share.

On April 30, 2020, we completed a public offering of 630,000 shares of common stock at an offering price of $5.00 per share. On May 6, 2020, we
issued an additional 94,500 shares of common stock at the same offering price pursuant to the exercise in full of the underwriter’s over-allotment option in
connection  with  the  aforementioned  offering.  As  a  result,  we  received  aggregate  net  proceeds  of  approximately  $3.0  million  after  underwriting  discounts,
commissions, legal and accounting fees, and other ancillary expenses. Due to anti-dilution provisions, the conversion price of the outstanding shares of Series
B preferred stock, which was issued in our February 2018 offering, was reduced to $5.00 per share.

On June 26, 2020, we completed a public offering of 1,000,000 shares of common stock at an offering price of $5.40 per share. On July 9, 2020, we
issued an additional 150,000 shares of common stock at the same offering price pursuant to the exercise in full of the underwriter’s over-allotment option in
connection  with  the  aforementioned  offering  resulting  in  $0.7  million  of  additional  net  proceeds.  As  a  result,  we  received  aggregate  net  proceeds  of
approximately $5.5 million including the overallotment option and after underwriting discounts, commissions, legal and accounting fees, and other ancillary
expenses.

On August 6, 2020, under our universal shelf registration statement filed on March 7, 2019 (the “Shelf Registration Statement,”), we completed a
public offering of 789,474 shares of common stock at an offering price of $7.60 per share. On August 11, 2020, we issued an additional 118,421 shares of
common stock at the same offering price pursuant to the exercise in full of the underwriter’s over-allotment option in connection with the aforementioned
offering. As a result, we received aggregate net proceeds of approximately $6.2 million after underwriting discounts, commissions, legal and accounting fees,
and other ancillary expenses.

On August 25, 2020, under the Shelf Registration Statement, we completed a public offering of 553,192 shares of common stock at an offering price
of $9.40 per share. On September 1, 2020, we issued an additional 50,000 shares of common stock at the same offering price pursuant to the exercise in full of
the underwriter’s over-allotment option in connection with the aforementioned offering. As a result, we received aggregate net proceeds of approximately $5.1
million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

On February 2, 2021, under the Shelf Registration Statement, we completed a bought deal offering of 500,000 shares of common stock at an offering
price of $28.80 per share. As a result, we received aggregate net proceeds of approximately $13.0 million after underwriting discounts, commissions, legal and
accounting fees, and other ancillary expenses.

January 2022 Offering

On January 14, 2022, the Company entered into a securities purchase agreement with several institutional investors pursuant to which the Company
agreed  to  sell  and  issue,  in  a  registered  direct  offering  (“January  2022  offering”),  an  aggregate  of  7,600  shares  of  the  Company’s  Series  D  Convertible
Preferred Stock, par value of $0.001 per share, at an offering price of $1,000 per share. Concurrently, the Company agreed to issue to these investors warrants
to purchase up to an aggregate of 807,500 shares of the Company’s common stock (the “Common Warrants”). As a result, the Company received aggregate
net proceeds of approximately $6.7 million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

In connection with the January 2022 offering and in accordance with the securities purchase agreement, we held a special meeting of stockholders on
March  11,  2022  to  consider  a  proposal  (the  “Proposal”)  to  amend  to  the  Company’s  Amended  and  Restated  Certificate  of  Incorporation,  as  amended  (the
“Charter”)  to  effect  a  reverse  split  of  the  outstanding  shares  of  the  Company’s  common  stock  at  a  ratio  between  1-for-5  and  1-for-20  (the  “Reverse  Split
Amendment”).  Our  stockholders  approved  the  Reverse  Split  Amendment  at  the  special  meeting.  On  March  11,  2022,  following  receipt  of  stockholder
approval,  our  Board  of  Directors  approved  a  reverse  split  ratio  of  1-for-20  and  we  filed  an  amendment  to  our  Charter  to  effect  such  reverse  stock  split,
effective as of 5:00 pm Eastern Time on March 14, 2022.

Pursuant to the purchase agreement, the Company filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State of
Delaware  designating  the  rights,  preferences  and  limitations  of  the  shares  of  Series  D  preferred  stock,  which  became  effective  on  January  14,  2022.  The
Certificate of Designation provided, in particular, that the Series D preferred stock will have no voting rights, other than the right to vote as a class on certain
matters,  except  that  each  share  of  Series  D  preferred  stock  had  the  right  to  cast  37,500  votes  per  share  of  Series  D  preferred  stock  on  the  Proposal  (the
“Supermajority Voting Rights”); provided, that the votes cast by the holders of the Series D preferred stock must be counted in the same proportion as the
aggregate shares of common stock voted on the Proposal. Because the Proposal was approved by our stockholders at the special meeting held on March 11,
2022, the Series D preferred stock no longer has Supermajority Voting Rights.

The holders of the Series D preferred stock are entitled to dividends, on an as-if converted basis, equal to dividends actually paid, if any, on shares of
Common Stock. The Series D preferred stock is convertible into shares of common stock at a conversion price of $8.00 per share, as adjusted for the most
recent  reverse  stock  split.  The  conversion  price  can  be  adjusted  pursuant  to  the  Certificate  of  Designation  for  stock  dividends  and  stock  splits,  subsequent
rights offerings, pro rata distributions of dividends or the occurrence of a fundamental transaction (as defined in the Certificate of Designation). The Series D
preferred stock can be converted at the option of the holders at any time. In addition, subject to the satisfaction of certain conditions, we may cause the holders
of the Series D preferred stock to convert their shares of Series D preferred stock; provided, that shares of Series D preferred stock cannot be converted to
common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election by such holder prior to the issuance of any shares of
Series D preferred stock, 9.99%) of our outstanding common stock. A holder of Series D preferred stock may, upon notice to us, increase or decrease such
beneficial ownership limitation, but not in excess of 9.99%. In March 2022, after the effectiveness of the Reverse Split Amendment, 5,200 shares of Series D
preferred stock were converted into an aggregate of 650,000 shares of common stock.

The  Common  Warrants  have  an  exercise  price  of  $9.60  per  share  and  become  exercisable  beginning  July  14,  2022.  The  Common  Warrants  will
expire five years following the time they become exercisable, or July 14, 2027. The Company also issued to the Placement Agent or its designees warrants to
purchase up to an aggregate of 66,500 shares of common stock (the “Placement Agent Warrants”). The Placement Agent Warrants are subject to the same
terms  as  the  Common  Warrants,  except  that  the  Placement  Agent  Warrants  have  an  exercise  price  of  $10.00  per  share  and  a  term  of  five  years  from  the
commencement of the sales pursuant to the January 2022 Offering, or January 12, 2027.

As a result of the issuance of the Common Warrants and Placement Agent Warrants issued in connection with our January 2022 offering, we expect a

significant non-cash charge which will reduce our net income in the first quarter of 2022.

PPP Loan

On April 23, 2020, the Company received loan proceeds of $2.3 million (the “PPP Loan”) pursuant to the PPP under the CARES Act. The PPP Loan,
which was in the form of a promissory note, dated April 20, 2020 (the “Promissory Note”), between the Company and Silicon Valley Bank (“SVB”) as the
lender, was set to mature on April 20, 2022 and bore interest at a fixed rate of 1% per annum, payable monthly commencing six months from the date of the
PPP Loan. The Company may voluntarily prepay the borrowings in full with no associated penalty or premium.

As previously disclosed, the PPP was administered by the U.S. Small Business Administration (the “SBA”). The SBA was given the authority under
the PPP to forgive loans if all employees were kept on the payroll for a required period and the loan proceeds were used for payroll, rent and utilities. The
Company applied for debt forgiveness in December 2020.

On April 17, 2021, the Company was notified by SVB that its PPP Loan had been fully forgiven by the SBA and that there was no remaining balance
on the PPP Loan. The Company recorded the forgiveness as other income in April 2021 in the amount of $2.4 million, of which approximately $23,000 was
accrued interest.

Contractual Obligations

Our principal obligations consist of the operating lease for our facility, our Loan Agreement with CRG and non-cancelable purchase commitments.

(1) Operating lease obligations primarily consist of leased office, laboratory, and manufacturing space under a non-cancelable operating lease. In addition to
the minimum future lease commitments presented above, the lease requires the Company to pay property taxes, insurance, maintenance, and repair costs.
The lease will expire on November 30, 2024.

(2) The total CRG Loan amount, shown as borrowings on the balance sheet as of December 31, 2021, is $12.3 million. The contractual obligation in the table
above of $19.4 million under the CRG Loan includes future interest to be accrued but not paid in cash as well as a $2.2 million back-end fee to be paid in
December 2025 upon maturity of the CRG Loan which is being accreted. Refer to Item 8, Financial Statements and Supplementary Data, Footnote 7 for
additional details.

(3) Noncancelable purchase commitments consist of agreements to purchase goods and services entered into in the ordinary course of business.

CRG Loan

On March 2, 2020, we and CRG further amended the Loan Agreement to change the date upon which cash payments for interest would commence
from the first quarter of 2020 to the third quarter of 2021. No cash payments for principal would be made until the final two years of the loan, which would
mature in June 2023 at the time. On May 12, 2020, we and CRG entered into another amendment to waive the requirement that we comply with the minimum
required revenue covenant for 2020 and granted us the ability to optionally prepay in whole or in part the outstanding principal amount of the Loan for the
Redemption Price. On January 22, 2021, we and CRG entered into yet another amendment to extend the maturity date of the Loan Agreement from June 30,
2023 to December 31, 2025 while also extending the interest only payment period and the period we can make interest payments in PIK to December 31,
2023. This amendment also established minimum revenue covenants of $12 million for 2023, $14.5 million for 2024, and $17.5 million for 2025, among other
things. The total CRG Loan amount, shown as long-term borrowings on the balance sheet as of December 31, 2021, is $12.3 million. However, upon maturity
of the debt in December 2025, we will be obligated to pay $19.4 million under the CRG Loan, which includes future interest to be accrued but not paid in cash
as well as a $2.2 million back-end fee to be paid in December 2025 upon maturity of the CRG Loan which is being accreted to the maturity date. Refer to Item
8, Financial Statements and Supplementary Data, Footnote 7 for additional details.

Lease Agreements

Our  operating  lease  obligations  primarily  consist  of  leased  office,  laboratory,  and  manufacturing  space  under  a  non-cancelable  operating  lease.  In
addition to the minimum future lease commitments presented below, the lease requires us to pay property taxes, insurance, maintenance, and repair costs. The
lease  includes  a  rent  holiday  concession  and  escalation  clauses  for  increased  rent  over  the  lease  term.  Rent  expense  is  recognized  using  the  straight-line
method over the term of the lease. We record deferred rent calculated as the difference between rent expense and the cash rental payments.

The lease will expire on November 30, 2024. We are obligated to pay a total approximately $5.8 million in base rent payments through November

2024, beginning on December 1, 2019. The weighted average remaining lease term as of December 31, 2021 is 2.9 years.

Net cash used in operating activities for the year ended December 31, 2021 was $15.7 million, consisting primarily of a net loss of $17.4 million and
a decrease in net operating assets of approximately $0.4 million, partially offset by net non-cash charges of $1.3 million. We recognized a non-cash gain on
extinguishment  of  debt  due  to  the  forgiveness  of  the  PPP  Loan  of  $2.4  million.  This  gain  was  partially  offset  by  non-cash  charges  related  to  stock-based
compensation of $1.0 million, non-cash interest expense of $1.6 million, and depreciation of $0.7 million. The decrease in net operating assets was primarily
due to an increase in accounts payable and other long-term liabilities; partially offset by the increase in inventory and a decrease in accrued compensation.

Net cash used in operating activities for the year ended December 31, 2020 was $14.8 million, consisting primarily of a net loss of $19.0 million and
an increase in net operating assets of approximately $0.6 million, partially offset by non-cash charges of $4.7 million. Non-cash charges largely related to
stock-based  compensation  of  $1.5  million,  non-cash  interest  expense  and  other  charges  of  $1.5  million,  depreciation  and  amortization  of  $0.9  million  and
provisions for excess and obsolete inventory of $0.5 million. The increase in net operating assets was primarily due to the increase in inventory and a decrease
in accrued compensation.

Net Cash (Used in) Provided by Investing Activities

Net cash used in investing activities during the year ended December 31, 2021 of $34,000 consisted of purchases of property and equipment.

Net cash provided by investing activities during the year ended December 31, 2020 was $65,000 consisting of proceeds from the sale of property and

equipment.

Net Cash Provided by Financing Activities

Net cash provided by financing activities in the year ended December 31, 2021 of $13.0 million relates to proceeds from the issuance of common

stock in our February 2021 public offering, net of various issuance costs.

Net cash provided by financing activities in the year ended December 31, 2020 of $26.0 million primarily relates to $23.6 million of proceeds from
the issuance of common stock in our public offerings, net of various issuance costs and proceeds of $2.3 million from borrowings pursuant to the PPP Loan
under the CARES Act.

Critical Accounting Policies and Estimates

Management’s  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  is  based  on  our  financial  statements,  which  have  been
prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and
assumptions for the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. Our estimates are
based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for
making  judgments  about  the  carrying  value  of  assets  and  liabilities  that  are  not  readily  apparent  from  other  sources.  Actual  results  may  differ  from  these
estimates under different assumptions or conditions and any such differences may be material.

While our significant accounting policies are more fully described in Note 2 of our financial statements included in this Annual Report on Form 10-
K, we believe the following discussion addresses our most critical accounting policies, which are those that are most important to our financial condition and
results of operations and require our most difficult, subjective and complex judgments.

Revenue Recognition

The  Company’s  revenues  are  derived  from  (1)  sale  of  Lightbox  consoles,  (2)  sale  of  disposables,  which  consist  of  catheters  and  accessories,  and
(3)  sale  of  customer  service  contracts  and  maintenance.  The  Company  sells  its  products  directly  to  hospitals  and  medical  centers  as  well  as  through
distributors. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the
rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company’s revenues
are  measured  based  on  consideration  specified  in  the  contract  with  each  customer,  net  of  any  sales  incentives  and  taxes  collected  from  customers  that  are
remitted to government authorities. For all sales, the Company uses either a signed agreement or a binding purchase order as evidence of an arrangement. The
Company’s revenue recognition policies generally result in revenue recognition at the following points:

1.

2.

3.

Lightbox console sales: Provided all other criteria for revenue recognition have been met, the Company recognizes revenue for Lightbox
console sales directly to end customers when delivery and acceptance occurs, which is defined as receipt by the Company of an executed
form that the installation process is complete.

Sales of disposables: Disposable revenues consist of sales of the Company’s catheters and accessories and are recognized when the product
has shipped, risk of loss and title has passed to the customer and collectability is reasonably assured.

Service  revenue:  Service  contract  revenue  consists  of  preventative  maintenance,  upgrades,  and  service  contracts.  Service  contracts  are
recognized ratably over the term of the service period and maintenance contract revenue is recognized as work is performed. To date, service
revenue has been insignificant.

The  Company  offers  its  customers  the  ability  to  purchase  or  lease  the  Lightbox  console.  In  addition,  the  Company  provides  a  Lightbox  under  a
limited commercial evaluation program to allow accounts to install and utilize the Lightbox for a limited trial period. When a Lightbox is placed under a lease
agreement  or  under  a  commercial  evaluation  program,  the  Company  retains  title  to  the  equipment  and  it  remains  capitalized  on  its  balance  sheet  under
property and equipment. Depreciation expense on these placed Lightboxes is recorded to cost of revenues on a straight-line basis. The costs to maintain these
placed Lightboxes are charged to cost of revenues as incurred.

The Company evaluates its lease and commercial evaluation program agreements and accounts for these contracts under the guidance in Accounting
Standards Codification (“ASC”) 842, Leases and ASU No. 2014 09, Revenue from Contracts with Customers (Topic 606). The guidance requires arrangement
consideration to be allocated between a lease deliverable and a non-lease deliverable based upon the relative selling-price of the deliverables.

The Company assessed whether the embedded lease is an operating lease or sales-type lease. Based on the Company’s assessment of the guidance
and given that any payments under the lease agreements are dependent upon contingent future sales, it was determined that collectability of the minimum
lease  payments  is  not  reasonably  predictable.  Accordingly,  the  Company  concluded  the  embedded  lease  did  not  meet  the  criteria  of  a  sales-type  lease  and
accounts for it as an operating lease. The Company recognizes revenue allocated to the lease as the contingent disposable product purchases are delivered and
are included in revenues within the statement of operations and comprehensive loss.

For  sales  through  distributors,  the  Company  recognizes  revenue  when  control  of  the  product  transfers  from  the  Company  to  the  distributor.  The
distributors are responsible for all marketing, sales, training and warranty in their respective territories. The standard terms and conditions contained in the
Company’s distribution agreements do not provide price protection or stock rotation rights to any of its distributors. In addition, its distributor agreements do
not allow the distributor to return or exchange products, and the distributor is obligated to pay the Company upon invoice regardless of its ability to resell the
product.

Inventories

Inventories  are  valued  at  the  lower  of  cost  or  net  realizable  value.  Cost  is  determined  using  the  first-in,  first-out  method  for  all  inventories.  The
Company’s policy is to write down inventory that has expired or become obsolete, inventory that has a cost basis in excess of its expected net realizable value,
and inventory in excess of expected requirements. At each balance sheet date, management evaluates inventories for excess quantities, and obsolescence. This
evaluation  by  management  includes  analysis  of  historical  sales  levels  by  product,  projections  of  future  demand,  the  risk  of  technological  or  competitive
obsolescence  for  products,  general  market  conditions,  as  well  as  the  feasibility  of  reworking  or  using  excess  or  obsolete  products  or  components  in  the
production  or  assembly  of  other  products  that  are  not  obsolete  or  for  which  there  are  not  excess  quantities  in  inventory.  To  the  extent  that  management
determines there are excess or obsolete inventory, management adjusts the carrying value to estimated net realizable value. When quantities on hand exceed
sales forecasts, a write-down is recorded for such excess inventories along with a corresponding charge to cost of revenues. The estimate of excess quantities
is  subjective  and  primarily  dependent  on  the  estimates  of  future  demand  for  a  particular  product.  Specifically,  the  future  demand  is  derived  based  on  our
historical experience, from discussion with users of our products and general market conditions. Changes in assumptions of product demand could have a
significant impact on the amount of write-down recorded. Inventory used in clinical trials is expensed at the time of production and recorded as research and
development  expense.  We  also  regularly  review  the  cost  of  inventories  against  estimated  market  value  and  record  a  lower  of  cost  or  market  reserve  for
inventories that have a cost in excess of estimated market value, which could have a material impact on our gross margin and inventory balances based on
additional write-downs to net realizable value or a benefit from inventories previously written down.

Stock-Based Compensation

Stock-based compensation for the Company includes amortization related to all stock options, restricted stock units (“RSU”), based on the grant-date
estimated fair value. The Company measures the fair value of RSUs using the closing stock price of a share of the Company’s common stock on the grant date
and  is  recognized  as  expense  on  a  straight-line  basis  over  the  vesting  period  of  the  award.  As  allowed  under  ASU  No.  2016‑09,  Compensation-Stock
Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, the Company accounts for forfeitures as they occur. There haven’t
been any recent grants of stock options.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

The risk associated with fluctuating interest rates is primarily limited to our cash equivalents, which are carried at quoted market prices. Due to the
short-term maturities and low risk profile of our cash equivalents, an immediate 100 basis point change in interest rates would not have a material effect on the
fair value of our cash equivalents. We do not currently use or plan to use financial derivatives in our investment portfolio.

Credit Risk

As of December 31, 2021, our cash and cash equivalents were maintained with one financial institution in the United States, and our current deposits
are likely in excess of insured limits. We have reviewed the financial statements of this institution and believe it has sufficient assets and liquidity to conduct
its operations in the ordinary course of business with little or no credit risk to us.

Our  accounts  receivable  primarily  relate  to  revenues  from  the  sale  of  our  Lumivascular  platform  products  to  hospitals  and  medical  centers  in  the
United  States.  At  December  31,  2021  and  2020,  there  was  one  customer  that  represented  21%  and  14%  of  accounts  receivable.  For  the  year  ended
December  31,  2021,  there  was  one  customer  that  represented  10%  of  revenues.  For  the  year  ended  December  31,  2020,  there  were  no  customers  that
represented 10% or more of revenues.

Foreign Currency Risk

Our business is primarily conducted in U.S. dollars. Any transactions that may be conducted in foreign currencies are not expected to have a material

effect on our results of operations, financial position or cash flows.

ITEM 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We  maintain  disclosure  controls  and  procedures  that  are  designed  to  ensure  that  information  required  to  be  disclosed  in  our  reports  under  the
Securities Exchange Act of 1934, as amended, or the Exchange Act, and the rules and regulations thereunder, 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  officer  and  principal  financial  officer,  as  appropriate,  to  allow  for  timely  decisions  regarding  required  disclosure.  In  designing  and
evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can
provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit
relationship of possible controls and procedures.

As required by Rule 13a-15(b) under the Exchange Act, our management, under the supervision and with the participation of our principal executive
officer and principal financial officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is
defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2021. Based on such evaluation, our principal executive officer and
principal financial officer have concluded that, as of December 31, 2021, our disclosure controls and procedures were effective.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of the
Exchange  Act.  Our  management  conducted  an  evaluation  of  the  effectiveness  of  our  internal  control  over  financial  reporting  based  on  the  framework  in
Internal  Control—Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Based  on  this
evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2021.

This  Annual  Report  on  Form  10-K  does  not  include  an  attestation  report  of  our  registered  public  accounting  firm  on  our  internal  control  over
financial reporting We are currently a non-accelerated filer and are therefore not required to provide an attestation report on our internal control over financial
reporting until such time as we are an accelerated filer or large accelerated filer.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) and 15d-
15(d) of the Exchange Act that occurred during the year ended December 31, 2021 that materially affected, or are reasonably likely to materially affect, our
internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our chief executive officer and chief financial officer, believes that our disclosure controls and procedures and internal
control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level.
However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors
and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the
control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be
considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all
control  issues  and  instances  of  fraud,  if  any,  have  been  detected.  These  inherent  limitations  include  the  realities  that  judgments  in  decision-making  can  be
faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons,
by  collusion  of  two  or  more  people  or  by  management  override  of  the  controls.  The  design  of  any  system  of  controls  also  is  based  in  part  upon  certain
assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential
future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may
deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

formation in September 2009 until the acquisition of its Unisyn business by GE Healthcare in May 2013, Mr. Soinski served as Chief Executive Officer of
Medical Imaging Holdings and its primary operating company Unisyn Medical Technologies, a national provider of technology-enabled products and services
to the medical imaging industry. Mr. Soinski was a Director of Medical Imaging Holdings and its remaining operating company Consensys Imaging Service
from September 2009 until its sale in October 2017. Mr. Soinski served periodically as a Special Venture Partner from July 2008 to June 2013 and as a Special

our Non-Executive Chairman since December 2017. During the last five years, Mr. Cullen has held board and committee positions with various companies.

James B. McElwee has served as a member of our board of directors since March 2011. Mr. McElwee has served as an independent venture capital
investor  since  2010.  Mr.  McElwee  served  as  general  partner  of  Weston  Presidio,  a  private  equity  and  venture  capital  firm,  from  1992  to  2010.  During  his
tenure as a general partner and member of the investment committee, Weston Presidio led the start up financing of JetBlue Airways and made investments in
Fender Musical Instruments, The Coffee Connection, Guitar Center, Mapquest, Party City, Petzazz, RE/MAX, and others.

We believe Mr. McElwee is qualified to serve as a member of our board of directors because of his substantial corporate development and business

strategy expertise gained in the venture capital industry.

Tamara N. Elias, M.D., was appointed to our board of directors in December 2019. Dr. Elias currently serves as VP, Head of Global Partnerships at
Merck. Previously she served as Vice President of Clinical Product Development at Aetna from February 2018 to December 2019. From 2015 to 2017, Dr.

management consultant at McKinsey, advising pharmaceutical, diagnostic and device companies in R&D, product commercialization and M&A. She currently
serves on the board of REVA Medical and has also previously served on the boards of several private companies, including Millennium Pharmacy Systems
(sold to PharMerica), BreatheAmerica and Influence Health (sold to Healthgrades) as well on the public company board of ATS Medical (sold to Medtronic).

strategy expertise and her experience in the healthcare industry.

Code of Business Conduct

We  have  adopted  a  code  of  business  conduct  that  applies  to  all  of  our  employees,  officers  and  directors,  including  those  officers  responsible  for
financial reporting. The code of business conduct is available on our website at www.avinger.com. Updates to or waivers of the code will be disclosed on the
same website. We intend to satisfy the disclosure requirement under Item 5.05 of Form 8-K regarding any amendment to, or waiver of, any provision of the
code in the future by disclosing such information on our website.

Board Leadership Structure

We  believe  that  the  structure  of  our  board  of  directors  and  its  committees  provides  strong  overall  management  of  our  company.    Our  board  of
directors does not have a formal policy on whether the roles of Chief Executive Officer and Chairman of our board of directors should be separate.  However,
Messrs. Soinski and Cullen, respectively, hold these positions at present.

Our Chief Executive Officer, Mr. Soinski, is responsible for setting the strategic direction of our company, the general management and operation of
the business and the guidance and oversight of senior management.  In his capacity as Chairman of our board of directors, Mr. Cullen is also responsible for
the guidance and oversight of senior management, monitoring the content, quality and timeliness of information sent to our board of directors, consultation
with our board of directors regarding the oversight of our business affairs, presiding over meetings of our board of directors and performing such additional
duties as our Board may otherwise determine and delegate.  At the end of each board meeting, the independent directors are expected to meet in executive
session,  without  Mr.  Soinski  present.    Following  each  meeting,  Mr.  Cullen  is  expected  to  provide  feedback  to  Mr.  Soinski  on  his  performance  and  the
performance of our employees during the meeting and to recommend new agenda items for the next meeting.

Director Independence

Our common stock is listed on The Nasdaq Capital Market.  Under the Nasdaq listing standards, independent directors must comprise a majority of a
listed company’s board of directors.  In addition, the Nasdaq listing standards require that, subject to specified exceptions, each member of a listed company’s
audit, compensation, and nominating and corporate governance committees be independent.  Under the Nasdaq listing standards, a director will only qualify as
an “independent director” if, in the opinion of that listed company’s board of directors, that director does not have a relationship that would interfere with the
exercise of independent judgment in carrying out the responsibilities of a director.

Audit committee members must also satisfy the additional independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934,
as  amended,  or  the  “Exchange  Act,  and  the  Nasdaq  listing  standards.    Compensation  committee  members  must  also  satisfy  the  additional  independence
criteria set forth in Rule 10C-1 under the Exchange Act and the Nasdaq listing standards. 

Our  board  of  directors  has  undertaken  a  review  of  the  independence  of  each  of  our  directors.    Based  on  information  provided  by  each  director
concerning his background, employment and affiliations, our board of directors has determined that Messrs. Cullen, McElwee and Dr. Elias do not have a
relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is
“independent” as that term is defined under the Nasdaq listing standards.  In making these determinations, our board of directors considered the current and
prior  relationships  that  each  non-employee  director  has  with  our  company  and  all  other  facts  and  circumstances  our  board  of  directors  deemed  relevant  in
determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them
described below under the heading “Related Person Transactions.”

Board Meetings and Committees

During our fiscal year ended December 31, 2021, our board of directors held 12 meetings (including regularly scheduled and special meetings), and
each director attended at least 75% of the aggregate of (i) the total number of meetings of our board of directors held during the period for which he has been a
director and (ii) the total number of meetings held by all committees of our board of directors on which he served during the periods that he served.  All of our
directors who were directors at the time attended our 2021 annual meeting of stockholders telephonically.

Although we do not have a formal policy regarding attendance by members of our board of directors at annual meetings of stockholders, we strongly

encourage our directors to attend.

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee.  The
composition and responsibilities of each of the committees of our board of directors are described below.  Members will serve on these committees until their
resignation or until as otherwise determined by our board of directors.

Audit Committee

Messrs. McElwee, Cullen and Dr. Elias serve on our audit committee.  Mr. Cullen serves as the chair of the audit committee.  Our board of directors
has  assessed  whether  all  members  of  the  audit  committee  meet  the  composition  requirements  of  Nasdaq,  including  the  requirements  regarding  financial
literacy and financial sophistication.  Our board of directors found that Messrs. McElwee, Cullen and Dr. Elias have met the financial literacy and financial
sophistication requirements and that Messrs. McElwee, Cullen and Dr. Elias are independent under SEC and Nasdaq rules.  In addition, our board of directors
has determined that Mr. Cullen is an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K under the Securities Act of 1933,
as amended, or the Securities Act.  The audit committee’s primary responsibilities include:

● appointing, approving the compensation of, and assessing the qualifications and independence of our independent registered public accounting

firm, which currently is Moss Adams LLP;

● reviewing and discussing with management and our independent registered public accounting firm our annual and quarterly financial statements

and related disclosures;

● preparing the audit committee report required by SEC rules to be included in our annual proxy statements;

● monitoring our internal control over financial reporting, disclosure controls and procedures;

● reviewing our risk management status;

● establishing policies regarding hiring employees from our independent registered public accounting firm and procedures for the receipt and

retention of accounting related complaints and concerns;

● meeting independently with our independent registered public accounting firm and management; and

● monitoring compliance with the code of business conduct and ethics for financial management.

All audit and non-audit services must be approved in advance by the audit committee.  Our audit committee operates under a written charter that
satisfies the applicable rules and regulations of the SEC and Nasdaq listing standards.  A copy of the charter of our audit committee is available on our website
at www.avinger.com under “Investors–Governance.” During our fiscal year ended December 31, 2021, our audit committee held four meetings.

Compensation Committee

Messrs. Cullen, McElwee and Dr. Elias serve on our compensation committee.  Mr. McElwee serves as the chair of the compensation committee. 
Each  member  of  our  compensation  committee  meets  the  requirements  for  independence  for  compensation  committee  members  under  the  Nasdaq  listing
standards  and  SEC  rules  and  regulations,  including  Rule  10C-1  under  the  Exchange  Act.    Each  member  of  our  compensation  committee  is  also  a  non-
employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act, and an outside director, as defined pursuant to Section 162(m) of
the Internal Revenue Code.  Our compensation committee is responsible for, among other things:

● annually reviewing and approving corporate goals and objectives relevant to compensation of our chief executive officer and our other executive

officers;

● determining the compensation of our chief executive officer and our other executive officers;

● reviewing and making recommendations to our board of directors with respect to director compensation; and

● overseeing and administering our equity incentive plans.

Our Chief Executive Officer and Chief Financial Officer make compensation recommendations for our other executive officers and initially propose
the corporate and departmental performance objectives under our Executive Incentive Compensation Plan to the compensation committee.  From time to time,
the compensation committee may use outside compensation consultants to assist it in analyzing our compensation programs and in determining appropriate
levels of compensation and benefits.  For example, we have periodically engaged Radford, a business unit of Aon Hewitt, to help develop our compensation
philosophy,  select  a  group  of  peer  companies  to  use  for  compensation  benchmarking  purposes  and  advise  on  cash  and  equity  compensation  levels  for  our
directors, executives and other employees based on current market practices.  We did not use any compensation consultants during our year ended December
31,  2021.  Our  compensation  committee  operates  under  a  written  charter  that  satisfies  the  applicable  rules  and  regulations  of  the  SEC  and  Nasdaq  listing
standards.  A copy of the charter of our compensation committee is available on our website at www.avinger.com under “Investors–Governance.” During our
fiscal year ended December 31, 2021, our compensation committee held three meetings.

Nominating and Corporate Governance Committee

Messrs.  Cullen,  McElwee  and  Dr.  Elias  serve  on  our  nominating  and  governance  committee.    Dr.  Elias  serves  as  the  chair  of  the  nominating  and
governance committee.  Each member of our nominating and corporate governance committee meets the requirements for independence under the Nasdaq
listing standards and SEC rules and regulations.  Our nominating and corporate governance committee is responsible for, among other things:

● identifying individuals qualified to become members of our board of directors;

● recommending to our board of directors the persons to be nominated for election as directors and to each of our board’s committees;

● reviewing and making recommendations to our board of directors with respect to management succession planning;

● developing, updating and recommending to our board of directors corporate governance principles and policies; and

● overseeing the evaluation of our board of directors and committees.

Our nominating and corporate governance committee operates under a written charter that satisfies the applicable Nasdaq listing standards.  A copy
of the charter of our nominating and corporate governance committee is available on our website at www.avinger.com under “Investors–Governance.” During
our fiscal year ended December 31, 2021, our nominating and corporate governance committee held no meetings.

Considerations in Evaluating Director Nominees

Our nominating and corporate governance committee uses a variety of methods for identifying and evaluating director nominees. In its evaluation of
director  candidates,  our  nominating  and  corporate  governance  committee  will  consider  the  current  size  and  composition  of  our  board  of  directors  and  the
needs  of  our  board  of  directors  and  the  respective  committees  of  our  board  of  directors.  Some  of  the  qualifications  that  our  nominating  and  corporate
governance committee considers include, without limitation, issues of character, integrity, judgment, diversity of experience, independence, area of expertise,
corporate experience, length of service, potential conflicts of interest and other commitments. We also look for nominees who have skills and experience that
would  support  the  short  and  long-term  goals  and  strategy  of  the  Company.  Our  nominating  and  corporate  governance  committee  seeks  to  maintain  an
appropriate  balance  of  backgrounds,  skills,  knowledge,  and  experience  to  support  current  and  future  needs.  Nominees  must  also  have  the  ability  to  offer
advice and guidance to our Chief Executive Officer based on past experience in positions with a high degree of responsibility and be leaders in the companies
or institutions with which they are affiliated.

In  the  case  of  incumbent  directors  whose  terms  of  office  are  set  to  expire,  our  nominating  and  corporate  governance  committee  reviews  these
directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any
other relationships and transactions that might impair the directors’ independence.

Director candidates, including incumbent directors, must have sufficient time available in the judgment of our nominating and corporate governance
committee  to  perform  all  board  of  director  and  committee  responsibilities.  Members  of  our  board  of  directors  are  expected  to  prepare  for,  attend  and
participate in all board of director and applicable committee meetings. Other than the foregoing, there are no stated minimum criteria for director nominees,
although our nominating and corporate governance committee may also consider such other factors as it may deem, from time to time, are in our and our
stockholders’ best interests.

68

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Although our board of directors does not maintain a specific policy with respect to board diversity, our board of directors believes that our board of
directors  should  be  a  diverse  body,  and  our  nominating  and  corporate  governance  committee  considers  a  broad  range  of  backgrounds  and  experiences.  In
making determinations regarding nominations of directors, our nominating and corporate governance committee may take into account the benefits of diverse
viewpoints,  backgrounds,  and  experiences.  Our  nominating  and  corporate  governance  committee  also  considers  these  and  other  factors  as  it  oversees  the
annual  board  of  director  and  committee  evaluations.  After  completing  its  review  and  evaluation  of  director  candidates,  our  nominating  and  corporate
governance committee recommends to our full board of directors the director nominees for selection.

In addition to utilizing personal networks and relationships to identify potential candidates, our nominating and corporate governance committee may
also engage, if it deems appropriate, a professional search firm. The nominating and corporate governance committee conducts any appropriate and necessary
inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the board. The nominating and corporate
governance committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the board.

Stockholder Recommendations for Nominations to the Board of Directors

Our  nominating  and  corporate  governance  committee  will  consider  candidates  for  director  recommended  by  stockholders,  so  long  as  such
recommendations comply with our amended and restated certificate of incorporation, amended and restated bylaws and applicable laws, rules and regulations,
including those promulgated by the SEC. Our nominating and corporate governance committee will evaluate such recommendations in accordance with its
charter, our amended and restated bylaws, our policies and procedures for director candidates, as well as the regular director nominee criteria described above.
This  process  is  designed  to  ensure  that  our  board  of  directors  includes  members  with  diverse  backgrounds,  skills  and  experience,  including  appropriate
financial and other expertise relevant to our business. Eligible stockholders wishing to recommend a candidate for nomination should contact our Secretary in
writing.  Such  recommendations  must  include  information  about  the  candidate,  a  statement  of  support  by  the  recommending  stockholder,  evidence  of  the
recommending stockholder’s ownership of our common stock and a signed letter from the candidate confirming willingness to serve on our board of directors.
Our nominating and corporate governance committee has discretion to decide which individuals to recommend for nomination as directors.

Under our amended and restated bylaws, stockholders may also nominate candidates for our board of directors.  Any nomination must comply with
the  requirements  set  forth  in  our  amended  and  restated  bylaws  and  should  be  sent  in  writing  to  our  Secretary  at  400  Chesapeake  Drive,  Redwood  City,
California 94063.  To be timely for our 2022 annual meeting of stockholders, our Secretary must receive the nomination no earlier than August 22, 2022 and
no later than September 21, 2022.

ITEM 11.    EXECUTIVE COMPENSATION

Processes and Procedures for Compensation Decisions

Our compensation committee is responsible for the executive compensation programs for our executive officers and reports to our board of directors
on  its  discussions,  decisions  and  other  actions.    Our  compensation  committee  reviews  and  approves  corporate  goals  and  objectives  relating  to  the
compensation of our Chief Executive Officer, evaluates the performance of our Chief Executive Officer in light of those goals and objectives and determines

Executive Employment Letters

Jeffrey M. Soinski

Pursuant to the employment letter, as revised on September 9, 2020, between the Company and Jeffrey M. Soinski, our President and Chief Executive
Officer, Mr. Soinski is entitled to receive as compensation (i) a base salary of $400,000, (ii) a discretionary bonus targeted at 75% of his base salary, subject to
the achievement of certain goals mutually agreed upon by him and our board of directors and payable semi-annually; and (iii) other standard benefits provided
to each of the Company’s executive officers. The letter has no specific term and provides for at-will employment.

Pursuant  to  Mr.  Soinski’s  employment  offer  letter,  if,  within  the  12-month  period  following  a  “change  in  control,”  we  terminate  Mr.  Soinski’s
employment without “cause,” or Mr. Soinski resigns for “good reason” (as such terms are defined in Mr. Soinski’s employment offer letter), Mr. Soinski will
receive accelerated vesting as to 100% of his outstanding unvested stock options.  If we experience a change in control, and Mr. Soinski remains our employee
through such date, Mr. Soinski will receive accelerated vesting as to 50% of his outstanding unvested stock options and/or restricted stock.

If  we  terminate  Mr.  Soinski  without  cause  at  any  time,  he  will  be  entitled  to  receive  12  months  of  base  salary  and  COBRA  medical  and  dental
insurance coverage, in each case payable in substantially equal installments in accordance with our payroll practices, as severance, in exchange for signing and
not revoking a severance agreement and general release against us and our affiliates within 60 days following his termination of employment. 

Mark Weinswig

Pursuant to an employment offer letter between the Company and Mr. Weinswig, dated as of June 11, 2018, Mr. Weinswig is entitled to receive as
compensation  (i)  a  base  salary  of  $300,000;  (ii)  a  discretionary  bonus  targeted  at  40%  of  his  base  salary,  subject  to  achievement  of  mutually  agreed
performance goals and payable semi-annually; and (iii) other standard benefits provided to each of the Company’s executive officers. On September 9, 2020,
Mr. Weinswig’s target bonus percentage was increased from 40% to 60%.

401(k) Plan

We maintain a tax-qualified retirement plan that provides eligible employees with an opportunity to save for retirement on a tax advantaged basis. 
We may make a discretionary matching contribution to the 401(k) plan, and may make a discretionary employer contribution to each eligible employee each
year.  To date, we have not made any matching or profits sharing contributions into the 401(k) plan.  All participants’ interests in our matching and profit
sharing contributions, if any, vest pursuant to a four-year graded vesting schedule from the time of contribution.  Pre-tax contributions are allocated to each
participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions.  The 401(k) plan is intended
to  qualify  under  Sections  401(a)  and  501(a)  of  the  Code.    As  a  tax-qualified  retirement  plan,  contributions  to  the  401(k)  plan  and  earnings  on  those
contributions are not taxable to the employees until distributed from the 401(k) plan, and all contributions are deductible by us when made.

plan in 2021.

Potential Payments upon Termination or Change of Control

Jeffrey M. Soinski

In March 2018, we entered into a change of control and severance agreement with Jeffrey M. Soinski, which was subsequently amended in March
2020. Under this agreement, as amended, if, within the 18 month period following a “change of control,” we terminate Mr. Soinski’s employment other than
for “cause,” death or disability, or the employee resigns for “good reason” (as such terms are defined in the employee’s employment agreement) and, within 60
days  following  the  employee’s  termination,  the  employee  executes  an  irrevocable  separation  agreement  and  release  of  claims,  the  employee  is  entitled  to
receive  (i)  continuing  payments  of  severance  pay  at  a  rate  equal  to  the  employee’s  monthly  base  salary  and  pro-rated  target  bonus,  as  then  in  effect,  for  a
period of 12 months plus one month for every year of service completed for the Company (provided that such severance shall not exceed 18 months), (ii)
reimbursement of premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for employee and employee’s dependents for up
to 12 months, (iii) accelerated vesting as to 100% of the employee’s outstanding unvested stock options and/or restricted stock, and (iv) the extension of the
post-termination exercise period of any options held by the employee for a period of 1 year.  Additionally, if we experience a change in control, 50% of Mr.
Soinski’s  outstanding  unvested  stock  options  and/or  restricted  stock  will  vest.  In  the  event  of  any  conflict  between  Mr.  Soinski’s  change  of  control  and
severance agreement and his offer letter, described above under “Executive Employment Letters,” he will be entitled to the greater of the benefits provided by
either. The agreement also provides that if the employee is employed by the Company or the Company’s successor on the date that is 12 months following a
change  of  control,  then  the  employee  will  be  entitled  to  a  lump  sum  bonus  payment  in  an  amount  equal  to  what  the  employee  would  have  received  as  a
severance payment if the employee had been terminated other than for cause, death or disability.

Himanshu Patel

We previously entered into a change of control and severance agreement with Himanshu Patel, which was subsequently amended in March 2020.
Under  this  agreement,  as  amended,  if,  within  the  18  month  period  following  a  “change  of  control,”  we  terminate  Mr.  Patel’s  employment  other  than  for
“cause,” death or disability, or the employee resigns for “good reason” (as such terms are defined in the employee’s employment agreement) and, within 60
days  following  the  employee’s  termination,  the  employee  executes  an  irrevocable  separation  agreement  and  release  of  claims,  the  employee  is  entitled  to
receive  (i)  continuing  payments  of  severance  pay  at  a  rate  equal  to  the  employee’s  monthly  base  salary  and  pro-rated  target  bonus,  as  then  in  effect,  for  a
period of 12 months plus one month for every year of service completed for the Company (provided that such severance shall not exceed 18 months), (ii)
reimbursement of premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for employee and employee’s dependents for up
to 12 months, (iii) accelerated vesting as to 100% of the employee’s outstanding unvested stock options and/or restricted stock, and (iv) the extension of the
post-termination exercise period of any options held by the employee for a period of 1 year. The agreement also provides that if the employee is employed by
the Company or the Company’s successor on the date that is 12 months following a change of control, then the employee will be entitled to a lump sum bonus
payment in an amount equal to what the employee would have received as a severance payment if the employee had been terminated other than for cause,
death or disability.

Mark Weinswig

In June 2018, we entered into a change of control and severance agreement with Mark Weinswig, which was subsequently amended in March 2020.
Under this agreement, as amended, if, within the 18 month period following a “change of control,” we terminate Mr. Weinswig’s employment other than for
“cause,” death or disability, or the employee resigns for “good reason” (as such terms are defined in the employee’s employment agreement) and, within 60
days  following  the  employee’s  termination,  the  employee  executes  an  irrevocable  separation  agreement  and  release  of  claims,  the  employee  is  entitled  to
receive (i) continuing payments of severance pay at a rate equal to the employee’s monthly base salary and pro rated target bonus, as then in effect, for 12
months plus one month for every year of service completed for the Company (provided that such severance shall not exceed 18 months), (ii) reimbursement of
premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for employee and employee’s dependents for up to 12 months, (iii)
accelerated vesting as to 100% of the employee’s outstanding unvested stock options and/or restricted stock, and (iv) the extension of the post-termination
exercise  period  of  any  options  held  by  the  employee  for  a  period  of  1  year.    Additionally,  if  we  experience  a  change  in  control,  50%  of  Mr.  Weinswig’s
outstanding unvested stock options and/or restricted stock will vest. In the event of any conflict between Mr. Weinswig’s change of control and severance
agreement and his offer letter, described above under “Executive Employment Letters,” he will be entitled to the greater of the benefits provided by either. The
agreement also provides that if the employee is employed by the Company or the Company’s successor on the date that is 12 months following a change of
control,  then  the  employee  will  be  entitled  to  a  lump  sum  bonus  payment  in  an  amount  equal  to  what  the  employee  would  have  received  as  a  severance
payment if the employee had been terminated other than for cause, death or disability.

Executive Incentive Compensation Plan

Our  board  of  directors  has  adopted  an  Executive  Incentive  Compensation  Plan,  or  the  Bonus  Plan,  that  is  administered  by  our  compensation
committee.    The  Bonus  Plan  allows  our  compensation  committee  to  provide  cash  incentive  awards  to  selected  employees,  including  our  named  executive
officers, based upon performance goals established by our compensation committee.

Under the Bonus Plan, our compensation committee determines the performance goals applicable to any award, which goals may include, without
limitation:  attainment  of  research  and  development  milestones,  sales  bookings,  business  divestitures  and  acquisitions,  cash  flow,  cash  position,  earnings
(which may include any calculation of earnings, including but not limited to earnings before interest and taxes, earnings before taxes, earnings before interest,
taxes, depreciation and amortization and net earnings), earnings per share, net income, net profit, net sales, operating cash flow, operating expenses, operating
income,  operating  margin,  overhead  or  other  expense  reduction,  product  defect  measures,  product  release  timelines,  productivity,  profit,  return  on  assets,
return on capital, return on equity, return on investment, return on sales, revenue, revenue growth, sales results, sales growth, stock price, time to market, total
stockholder return, working capital, and individual objectives such as peer reviews or other subjective or objective criteria.  Performance goals that include our
financial results may be determined in accordance with GAAP or such financial results may consist of non-GAAP financial measures and any actual results
may be adjusted by the compensation committee for one-time items or unbudgeted or unexpected items when performance goals that include our financial
results may be determined in accordance with GAAP, or such financial results may consist of non-GAAP financial measures, and any actual results may be
adjusted by the compensation committee for one-time items or unbudgeted or unexpected items when determining whether the performance goals have been
met.    The  goals  may  be  on  the  basis  of  any  factors  the  compensation  committee  determines  relevant,  and  may  be  adjusted  on  an  individual,  divisional,
business unit or company-wide basis.  The performance goals may differ from participant to participant and from award to award.

Our compensation committee may, in its sole discretion and at any time, increase, reduce or eliminate a participant’s actual award, and/or increase,
reduce or eliminate the amount allocated to the bonus pool for a particular performance period.  The actual award may be below, at or above a participant’s
target  award,  in  the  compensation  committee’s  discretion.    Our  compensation  committee  may  determine  the  amount  of  any  reduction  on  the  basis  of  such
factors as it deems relevant, and it is not required to establish any allocation or weighting with respect to the factors it considers.

Actual  awards  are  paid  in  cash  only  after  they  are  earned,  which  usually  requires  continued  employment  through  the  date  a  bonus  is  paid.    Our
compensation committee has the authority to amend, alter, suspend or terminate the Bonus Plan provided such action does not impair the existing rights of any
participant with respect to any earned bonus.

Retention Bonuses

On  March  9,  2021,  the  Compensation  Committee  (the  “Committee”)  of  the  Board  of  Directors  of  the  Company  determined  to  provide  certain
incentive payments (the “Retention Bonuses”) to certain full-time executive officers and vice presidents of the Company, including Jeffrey M. Soinski, Mark
Weinswig, and Himanshu Patel, who serve as the Company’s Chief Executive Officer, Chief Financial Officer, and Chief Technology Officer, respectively
(the “Bonus Officers”), based on certain performance goals. The Retention Bonus consists of incentive payments in an amount equal to 100% of such Bonus
Officer’s annual salary as of December 31, 2023, 50% of which will be paid if such Bonus Officer is in good standing in their service at the Company on
December 31, 2023, and 50% to be paid if such Bonus Officer is in good standing in their service at the Company on December 31, 2024 (each, a “Retention
Bonus Payment”). The Retention Bonus Payments may be paid in cash or equity, or a combination of both, as determined by the Committee. In addition, the
Retention Bonus Payments shall accelerate in the event of a Change in Control, as defined in the Company’s Amended and Restated 2015 Equity Incentive
Plan,  provided  that  the  Bonus  Officer  remains  in  his  or  her  respective  position  through  such  Change  in  Control.  Each  Retention  Bonus  Payment  shall  be
increased in the event that the price of the common stock of the Company is above $60.00 (subject to adjustment for any stock splits, reverse stock splits, or
similar transactions) as of the date of such Retention Bonus Payment, according to the schedule below:

● If the stock price is between $60.00 and $79.99 (subject to adjustment for any stock splits, reverse stock splits, or similar transactions) as of the date

of the Retention Bonus Payment, such Retention Bonus Payment shall be increased by 25%;

● If the stock price is between $80.00 and $99.99 (subject to adjustment for any stock splits, reverse stock splits, or similar transactions) as of the date

of the Retention Bonus Payment, such Retention Bonus Payment shall be increased by 50%; and

● If the stock price is $100.00 or above (subject to adjustment for any stock splits, reverse stock splits, or similar transactions) as of the date of the

Retention Bonus Payment, such Retention Bonus Payment shall be increased by 100%.

The Retention Bonuses are in addition to any other bonus to which the Bonus Officers may be entitled under the Company’s Bonus Plan.

Director Compensation

Our board of directors approved our Outside Director Compensation Policy in January 2015 to compensate each non-employee director for his or her
service,  and  amended  certain  aspects  of  this  policy  in  August  2018.    Our  board  of  directors  will  have  the  discretion  to  revise  non-employee  director
compensation as it deems necessary or appropriate.  Under our Outside Director Compensation Policy, non-employee directors will receive compensation in
the form of equity and cash, as described below:

Cash Compensation.  All non-employee directors will be entitled to receive the following cash compensation for their services:

● $35,000 per year for service as a board member;

● $25,000 per year additionally for service as chairman of the board;

● $20,000 per year additionally for service as chairman of the audit committee;

● $10,000 per year additionally for service as an audit committee member;

● $15,000 per year additionally for service as chairman of the compensation committee;

● $7,500 per year additionally for service as a compensation committee member;

● $10,000 per year additionally for service as chairman of the nominating and corporate governance committee; and

● $5,000 per year additionally for service as a nominating and corporate governance committee member.

All cash payments to non-employee directors, or the Retainer Cash Payments, will be paid semiannually with the first semiannual installment payable
on the date of our annual meeting of stockholders or, if no annual meeting occurs in a given year, May 1, and the second semiannual installment payable on
November 1 of each year.

Election  to  Receive  RSUs  in  Lieu  of  Cash  Payments.   All  non-employee  directors  may  elect  to  convert  a  Retainer  Cash  Payment  into  RSUs,  or
Retainer RSUs, with a grant date fair value equal to the applicable Retainer Cash Payment.  Each Retainer RSU will be granted on the date that the applicable
Retainer Cash Payment was scheduled to be paid, and all of the shares underlying the Retainer RSUs will vest and become exercisable six months from the
date of grant, subject to continued service as a director through the applicable vesting date.  The Retainer RSUs will be subject to certain terms and conditions
as described below under the section titled “Director Compensation—Equity Compensation.”

Elections to convert a Retainer Cash Payment into a Retainer RSU must generally be made on or prior to December 31 of the year prior to the year in
which the Retainer Cash Payment is scheduled to be paid, or such earlier deadline as is established by our board of directors or compensation committee.  A
newly appointed non-employee director will be permitted to elect to convert Retainer Cash Payments payable in the same calendar year into Retainer RSUs,
provided that such election is made prior to the date the individual becomes a non-employee director.

Equity Compensation.  Nondiscretionary, automatic grants of RSUs will be made to our non-employee directors.

● Initial Grant.  Generally, each person who first becomes a non-employee director will be granted RSUs having a grant date fair value equal to

$115,000, or the Initial Grant.  The Initial Grant will typically be granted on the date of the first meeting of our board of directors or
compensation committee occurring on or after the date on which the individual first became a non-employee director.  The Initial Grant will vest
and become exercisable as to one thirty-sixth (1/36th) of the shares subject to such Initial Grant on each monthly anniversary of the
commencement of the non-employee director’s service as a director, subject to the continued service as a director through the applicable vesting
date.

● Annual Grant.  Once each calendar year, on the same date that our board of directors grants annual equity awards to our senior executives, each
non-employee director will be granted RSUs having a grant date fair value equal to $75,000, or the Annual Grant.  All of the shares underlying
the Annual Grant will vest and become exercisable one year from the date of grant, subject to continued service as a director through the
applicable vesting date.

The grant date fair value is the closing sales price for the Company’s common stock (or the closing bid, if no sales were reported) as quoted on such

exchange or system on the date such award is granted.

Any  RSUs  granted  under  our  outside  director  compensation  policy  will  fully  vest  and  become  exercisable  in  the  event  of  a  change  in  control,  as
defined in our 2015 Plan, provided that the holder remains a director through such change in control.  Further, our 2015 Plan provides that in the event of a
merger or change in control, as defined in our 2015 Plan, each outstanding equity award granted under our 2015 Plan that is held by a non-employee director
will fully vest, all restrictions on the shares subject to such award will lapse and, with respect to awards with performance-based vesting, all performance goals
or  other  vesting  criteria  will  be  deemed  achieved  at  100%  of  target  levels,  and  all  of  the  shares  subject  to  such  award  will  become  fully  exercisable,  if
applicable, provided such optionee remains a director through such merger or change in control.

in the form of RSUs.

Directors  who  are  also  our  employees  receive  no  additional  compensation  for  their  service  as  directors.    During  2021,  Jeffrey  M.  Soinski,  our
President,  Chief  Executive  Officer  and  a  director,  was  also  our  employee.    See  the  section  titled  “Summary  Compensation  Table”  below  for  additional
information about the compensation for Mr. Soinski.

Officer and Director Share Purchase Plan

On August 22, 2018, the Board of Directors of the Company approved the adoption of an Officer and Director Share Purchase Plan (“ODPP”), which
allows executive officers and directors to purchase shares of our common stock at fair market value in lieu of salary or, in the case of directors, director fees.
Eligible individuals may voluntarily participate in the ODPP by authorizing payroll deductions or, in the case of directors, deductions from director fees for
the  purpose  of  purchasing  common  stock.  Elections  to  participate  in  the  ODPP  may  only  be  made  during  open  trading  windows  under  our  insider  trading
policy when the participant does not otherwise possess material non-public information concerning the Company. The Board of Directors authorized 1,000
shares to be made available for purchase by officers and directors under the ODPP. Effective on August 28, 2019 and March 10, 2020, the Board of Directors
approved an additional 2,000 and 6,250 shares, respectively, to be made available under the ODPP. Common stock issued under the ODPP during the year
ended December 31, 2020 totaled 2,652 shares. As of December 31, 2021, there were 4,609 shares reserved for issuance under the ODPP.

shares of common stock, (ii) 5.0% of the aggregate number of shares of common stock outstanding on the last day of the preceding fiscal year, or (iii)
such number of shares that may be determined by our board of directors.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth certain information with respect to the beneficial ownership of our capital stock as of December 31, 2021 for:

● each person or group of affiliated persons known by us to be the beneficial owner of more than 5% of our common stock;

● each of our named executive officers;

● each of our directors and nominees for director; and

● all of our current executive officers and directors as a group.

We have determined beneficial ownership in accordance with the rules and regulations of the SEC, and the information is not necessarily indicative
of beneficial ownership for any other purpose.  Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons
and entities named in the table below have sole voting and sole investment power with respect to all shares of our capital stock that they beneficially own,
subject to applicable community property laws.

Applicable percentage ownership is based on 4,778,263 shares of our common stock outstanding as of December 31, 2021. In computing the number
of shares of capital stock beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares of our capital
stock subject to options held by the person that are currently exercisable or exercisable within 60 days of December 31, 2021.  However, we did not deem such
shares of our capital stock outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Avinger, Inc., 400 Chesapeake Drive, Redwood City,
California 94063. The information provided in the table is based on our records, information filed with the SEC and information provided to us, except where
otherwise noted.

ITEM 13.    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Related Person Transactions

We describe below transactions and series of similar transactions, since January 1, 2020, to which we were a party or will be a party, in which:

● the amounts involved exceeded or will exceed the lesser of $120,000 or 1% of the average of our total assets at year end for the last two completed

fiscal years; and

● any  of  our  directors,  nominees  for  director,  executive  officers  or  beneficial  holders  of  more  than  5%  of  our  outstanding  common  stock,  or  any
immediate family member of, or person sharing the household with, any of these individuals or entities (each, a related person), had or will have a
direct or indirect material interest.

We have entered into employment and separation arrangements with certain current and former executive officers.  For more information on these

employment and separation agreements, see the section titled “Executive Compensation - Executive Employment Letters” in Item 11 above.

We  have  entered  into  indemnification  agreements  with  our  directors  and  executive  officers.    The  indemnification  agreements,  as  well  as  our

certificate of incorporation and bylaws, require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law.

Policies and Procedures for Related Party Transactions

Our board of directors has adopted a written policy that our executive officers, directors, nominees for election as a director, beneficial owners of
more than 5% of any class of our common stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a
related person transaction with us without the prior consent of our audit committee.  Any request for us to enter into a transaction with an executive officer,
director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of
any of the foregoing persons in which the amount involved exceeds the lesser of $120,000 or 1% of the average of our total assets at year end for the last two
completed fiscal years and such person would have a direct or indirect interest must first be presented to our audit committee for review, consideration and
approval.  In approving or rejecting any such proposal, our audit committee is to consider the material facts of the transaction, including, but not limited to,
whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances and
the extent of the related person’s interest in the transaction.

Director Independence

Information regarding the independence of directors is disclosed above under Item 10 under the heading “Director Independence” and incorporated herein by

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of
Avinger, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Avinger, Inc. (the “Company”) as of December 31, 2021 and 2020, the related statements of operations
and comprehensive loss, stockholders’ equity, and cash flows for the years then ended, and the related notes and the financial statement schedules (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, 2021 and 2020, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles
generally accepted in the United States of America.

Basis for Opinion

These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s  financial
statements based on our audits. 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 audits 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 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  audits  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  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating
the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required
to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our
especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial
statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on
the accounts or disclosures to which it relates.

Valuation of Inventories

As described in Notes 2 and 4 to the financial statements, the Company’s inventories balance was $4.6 million as of December 31, 2021. The Company values
its inventories at lower of cost (determined using the first-in, first-out method) or net realizable value. The Company writes down inventory that has expired or
become obsolete, inventory that has a cost basis in excess of its expected net realizable value, and inventory in excess of expected requirements. The estimate
of  excess  quantities  is  subjective  and  primarily  dependent  on  the  estimates  of  future  demand  for  a  particular  product.  Changes  in  assumptions  of  product
demand could have a significant impact on the amount of write-down recorded. The evaluation by management includes analysis of historical sales levels by
product, projections of future demand, the risk of technological or competitive obsolescence for products, general market conditions, as well as the feasibility
of reworking or using excess or obsolete products or components in the production or assembly of other products that are not obsolete or for which there are
not excess quantities in inventory.

F-2

 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  identified  the  valuation  of  inventories,  in  particular  the  estimates  for  excess  quantities  and  obsolescence,  as  a  critical  audit  matter,  because  of  the
significant assumptions and subjective judgments used by management, which in turn led to the use of subjective auditor judgment and audit effort to address
the matter.

The primary procedures we performed to address the critical audit matter included:

● Evaluating management’s process for developing the estimates of excess and obsolete inventories by:

● Evaluating the methodology utilized to calculate the write-downs;

● Performing inquiries with management as to the composition of the reserve for inventory items without recent sales;

● Assessing the appropriateness of the formulaic calculation and management adjustments by product type; and

● Testing the mathematical accuracy of the formulaic calculation.

● Evaluating the reasonableness of the significant assumptions used by management including those related to future demand by:

● Evaluating management’s ability to provide reasonable forecast of sales by comparing prior period sales forecasts to actual results; and

● Performing inquiries with nonfinancial personnel, including sales and production employees, regarding obsolete or discontinued inventory items
and other factors to corroborate management’s assertions regarding qualitative judgments about excess and obsolete inventories or unrecorded
reserves.

● Testing the completeness, accuracy, and relevance of the underlying data used in management’s estimate and calculations related to the application of

the methodology to specific inventory categories by agreement to supporting documentation and recalculation.

● Performing  a  substantive  analytical  procedure,  whereby  we  developed  an  independent  expectation  of  the  excess  and  obsolescence  reserve  based

primarily on historical trends, and compared that expectation to the recorded amount.

Notes to Financial Statements

1. Organization

Organization, Nature of Business

Avinger,  Inc.  (the  “Company”),  a  Delaware  corporation,  was  incorporated  in  March 2007.  The  Company  designs,  manufactures  and  sells  image-
guided,  catheter-based  systems  that  are  used  by  physicians  to  treat  patients  with  peripheral  artery  disease  (“PAD”).  Patients  with  PAD  have  a  build-up  of
plaque in the arteries that supply blood to areas away from the heart, particularly the pelvis and legs. The Company manufactures and sells a suite of products
in the United States (“U.S.”) and in select international markets. The Company has developed its Lumivascular platform, which integrates optical coherence
tomography ( “OCT”) visualization with interventional catheters and is the industry’s only system that provides real-time intravascular imaging during the
treatment portion of PAD procedures. The Company’s Lumivascular platform consists of a capital component, our Lightbox consoles, as well as a variety of
disposable  catheter  products.  The  Company’s  current  catheter  products  includes  its  Lumivascular  platform  products,  Ocelot  and  Tigereye,  all  of  which  are
designed to allow physicians to penetrate a total blockage in an artery, known as a chronic total occlusion (“CTO”). The Company also has image-guided
atherectomy  solutions  under  its  suite  of  Lumivascular  products,  Pantheris  and  Pantheris  SV,  which  are  designed  to  allow  physicians  to  precisely  remove
arterial plaque in PAD patients. The Company is located in Redwood City, California.

Liquidity Matters

In the course of its activities, the Company has incurred losses and negative cash flows from operations since its inception. As of December 31, 2021,
the Company had an accumulated deficit of $384.8 million. The Company expects to incur losses for the foreseeable future. The Company believes that its
cash  and  cash  equivalents  of  $19.5  million  at  December  31,  2021,  together  with  approximately  $6.7  million  net  proceeds  from  the  January  2022  equity
financing, and expected revenues and funds from operations will be sufficient to allow the Company to fund its current operations through the second quarter
of 2023. The Company received net proceeds of approximately $3.9 million from the sale of its common stock in its January 2020 offering, $2.3 million of
loan proceeds in April 2020 pursuant to the Paycheck Protection Program (“PPP”) under the Coronavirus Aid, Relief and Economic Security (“CARES”) Act,
which was forgiven in April 2021, $3.0 million from the sale of its common stock in April and May 2020, $5.5 million from the sale of its common stock in
June and July 2020, $11.3 million from the sale of its common stock in August and September 2020, and approximately $13.0 million from the sale of its
common  stock  in  February  2021.  The  Company  does  not  have  any  immediate  plans  to  raise  additional  funds  through  future  equity  or  debt  financings.
However, the Company may decide to raise additional funds to meet its operational needs and capital requirements for product development, clinical trials and
commercialization or other strategic objectives.

The Company can provide no assurance that it will be successful in raising funds pursuant to additional equity or debt financings or that such funds
will be raised at prices that do not create substantial dilution for its existing stockholders. Given the volatility in the Company’s stock price, any financing that
we may undertake in the next twelve months could cause substantial dilution to its existing stockholders, there can be no assurance that the Company will be
successful in acquiring additional funding at levels sufficient to fund its various endeavors. In addition, the COVID-19 pandemic and responses thereto have
resulted in reduced consumer and investor confidence, instability in the credit and financial markets, volatile corporate profits, restrictions on elective medical
procedures,  and  reduced  business  and  consumer  spending,  which  could  increase  the  cost  of  capital  and/or  limit  the  availability  of  capital  to  the  Company.
During the second quarter of 2020, the Company took certain actions to manage available cash and other resources to mitigate the effects of COVID-19 on its
business, which included reduction of discretionary costs, reduction of base salaries for all of its non-manufacturing employees by 20% and reduction of hours
worked by its manufacturing workers by 20%. Salaries and hours worked largely returned to prior levels by July 2020.

On September 22, 2021, we  received  a  letter  from  Nasdaq’s  Listing  Qualifications  Department  notifying  us  that  we  were  not in compliance with
Nasdaq Listing Rule 5550(a)(2), as the minimum bid price for our listed securities was less than $1 for the previous 30 consecutive business days. We had a
period of 180 calendar days, or until March 21, 2022, to regain compliance with the rule referred to in this paragraph. To regain compliance, the bid price of
our common stock must close at $1 or more for a minimum of ten consecutive business days. The notice has no present impact on the listing of our securities
on Nasdaq. On March 14, 2022, we effected a 1-for-20 reverse stock split of our outstanding shares of common stock. However, there is no guarantee that
such reverse stock split will result in the bid price of our common stock closing at $1 or more for the required ten consecutive business days.

F- 8

 
 
 
 
 
 
 
 
 
 
 
 
 
The Company has not yet regained compliance with the Minimum Bid Price Requirement. In accordance with Nasdaq Listing Rule 5810(c)(3)(A),
the  Company  provided  written  notice  to  Nasdaq  requesting  an  additional  180  calendar  days  to  cure  the  deficiency  on  March  17,  2022,  but  have  not  yet
received a response. If Nasdaq delists our common stock from trading on its exchange and we are not able to list our securities on another national securities
exchange, we could face significant material adverse consequences including among other things, a decreased ability to issue additional securities or obtain
additional financing in the future, a limited availability of market quotations for our securities, reduced liquidity for our securities.

If the Company is unable to raise additional capital in sufficient amounts or on terms acceptable to it, the Company may have to significantly reduce
its operations or delay, scale back or discontinue the development of one or more of its products. The financial statements do not include any adjustments that
might result from the outcome of this uncertainty. The Company’s ultimate success will largely depend on its continued development of innovative medical
technologies, its ability to successfully commercialize its products and its ability to raise significant additional funding.

Public Offerings

On January 31, 2020, the Company completed a public offering of 321,429 shares of common stock at an offering price of $14.00 per share. As a
result,  the  Company  received  net  proceeds  of  approximately  $3.9  million  after  underwriting  discounts,  commissions,  legal  and  accounting  fees,  and  other
ancillary  expenses.  Due  to  anti-dilution  provisions,  the  conversion  price  of  the  outstanding  shares  of  Series  B  preferred  stock,  which  was  issued  in  the
February 2018 offering, was reduced to $14.00 per share.

On April 30, 2020, the Company completed a public offering of 630,000 shares of common stock at an offering price of $5.00 per share. On May 6,
2020, the Company issued an additional 94,500 shares of common stock at the same offering price pursuant to the exercise in full of the underwriter’s over-
allotment option in connection with the aforementioned offering. As a result, the Company received aggregate net proceeds of approximately $3.0 million
after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses. Due to anti-dilution provisions, the conversion price of the
outstanding shares of Series B preferred stock, which was issued in the February 2018 offering, was reduced to $5.00 per share.

On June 26, 2020, the Company completed a public offering of 1,000,000 shares of common stock at an offering price of $5.40 per share. On July 9,
2020, the Company issued an additional 150,000 shares of common stock at the same offering price pursuant to the exercise in full of the underwriter’s over-
allotment  option  in  connection  with  the  aforementioned  offering  resulting  in  $0.7  million  of  additional  net  proceeds.  As  a  result,  the  Company  received
aggregate net proceeds of approximately $5.5 million including the overallotment option and after underwriting discounts, commissions, legal and accounting
fees, and other ancillary expenses.

On August  6,  2020,  under  the  universal  shelf  registration  statement  filed  on  March  7,  2019  (the  “Shelf  Registration  Statement,”),  the  Company
completed a public offering of 789,474 shares of common stock at an offering price of $7.60 per share. On August 11, 2020, the Company issued an additional
118,421 shares of common stock at the same offering price pursuant to the exercise in full of the underwriter’s over-allotment option in connection with the
aforementioned offering. As a result, the Company received aggregate net proceeds of approximately $6.2 million after underwriting discounts, commissions,
legal and accounting fees, and other ancillary expenses.

On August 25, 2020, under the Shelf Registration Statement, the Company completed a public offering of 553,192 shares of common stock at an
offering price of $9.40 per share. On September 1, 2020, the Company issued an additional 50,000 shares of common stock at the same offering price pursuant
to the exercise in full of the underwriter’s over-allotment option in connection with the aforementioned offering. As a result, the Company received aggregate
net proceeds of approximately $5.1 million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

On February 2, 2021, under the Shelf Registration Statement, the Company completed a bought deal offering of 500,000 shares of common stock at
an offering price of $28.80 per share. As a result, the Company received aggregate net proceeds of approximately $13.0 million after underwriting discounts,
commissions, legal and accounting fees, and other ancillary expenses.

January 2022 Offering

On January 14, 2022, the Company entered into a securities purchase agreement with several institutional investors pursuant to which the Company
agreed  to  sell  and  issue,  in  a  registered  direct  offering  (  “January  2022  offering”),  an  aggregate  of  7,600  shares  of  the  Company’s  Series  D  Convertible
Preferred Stock, par value of $0.001 per share, at an offering price of $1,000 per share. Concurrently, the Company agreed to issue to these investors warrants
to purchase up to an aggregate of 807,500 shares of the Company’s common stock (the “Common Warrants”). As a result, the Company received aggregate
net proceeds of approximately $6.7 million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

F- 9

 
 
 
 
 
 
 
 
 
 
 
 
 
In  connection  with  the  January  2022  offering  and  in  accordance  with  the  securities  purchase  agreement,  the  Company  held  a  special  meeting  of
stockholders on March 11, 2022 to consider a proposal (the “Proposal”) to amend to the Company’s Amended and Restated Certificate of Incorporation, as
amended  (the  “Charter”)  to  effect  a  reverse  split  of  the  outstanding  shares  of  the  Company’s  common  stock  at  a  ratio  between  1-for-5  and  1-for-20  (the
“Reverse Split Amendment”). The Company’s stockholders approved the Reverse Split Amendment at the special meeting. On March 11, 2022, following
receipt of stockholder approval, the Company’s Board of Directors approved a reverse split ratio of 1-for-20  and  the  Company  filed  an  amendment  to  our
Charter to effect such reverse stock split, effective as of 5:00 pm Eastern Time on March 14, 2022.

Pursuant to the purchase agreement, the Company filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State of
Delaware  designating  the  rights,  preferences  and  limitations  of  the  shares  of  Series  D  preferred  stock,  which  became  effective  on  January  14,  2022.  The
Certificate of Designation provided, in particular, that the Series D preferred stock will have no voting rights, other than the right to vote as a class on certain
matters,  except  that  each  share  of  Series  D  preferred  stock  had  the  right  to  cast  37,500  votes  per  share  of  Series  D  preferred  stock  on  the  Proposal  (the
“Supermajority Voting Rights”); provided, that the votes cast by the holders of the Series D preferred stock must be counted in the same proportion as the
aggregate shares of common stock voted on the Proposal. Because the Proposal was approved by our stockholders at the special meeting held on March 11,
2022, the Series D preferred stock no longer has Supermajority Voting Rights.

The holders of the Series D preferred stock are entitled to dividends, on an as-if converted basis, equal to dividends actually paid, if any, on shares of
Common Stock. The Series D preferred stock is convertible into shares of common stock at a conversion price of $8.00 per share, as adjusted for the most
recent  reverse  stock  split.  The  conversion  price  can  be  adjusted  pursuant  to  the  Certificate  of  Designation  for  stock  dividends  and  stock  splits,  subsequent
rights offerings, pro rata distributions of dividends or the occurrence of a fundamental transaction (as defined in the Certificate of Designation). The Series D
preferred stock can be converted at the option of the holders at any time. In addition, subject to the satisfaction of certain conditions, the Company may cause
the holders of the Series D preferred stock to convert their shares of Series D preferred stock; provided, that shares of Series D preferred stock cannot be
converted to common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election by such holder prior to the issuance of any
shares of Series D preferred stock, 9.99%) of our outstanding common stock. A holder of Series D preferred stock may, upon notice to the Company, increase
or decrease such beneficial ownership limitation, but not in excess of 9.99%.

The  Common  Warrants  have  an  exercise  price  of  $9.60  per  share  and  become  exercisable  beginning  July  14,  2022.  The  Common  Warrants  will
expire five years following the time they become exercisable, or July 14, 2027. The Company also issued to the Placement Agent or its designees warrants to
purchase up to an aggregate of 66,500 shares of common stock (the “Placement Agent Warrants”). The Placement Agent Warrants are subject to the same
terms  as  the  Common  Warrants,  except  that  the  Placement  Agent  Warrants  have  an  exercise  price  of  $10.00  per  share  and  a  term  of  five  years  from  the
commencement of the sales pursuant to the January 2022 Offering, or January 12, 2027.

2. Summary of Significant Accounting Policies

Basis of Presentation

The  accompanying  financial  statements  have  been  prepared  in  accordance  with  United  States  generally  accepted  accounting  principles

(“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).

On March 11, 2022, the Company’s Board of Directors approved an amendment to the Company’s amended and restated certificate of incorporation
to effect a 1-for-20 reverse stock split of the Company’s issued and outstanding common stock. The reverse stock split became effective on March 14, 2022.
The par value of the common stock and preferred stock was not adjusted as a result of the reverse stock split. All common stock, stock options, restricted stock
units, and per share amounts in the financial statements have been retroactively adjusted for all periods presented to give effect to the reverse stock split.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the
amounts  and  disclosures  reported  in  the  financial  statements.  Management  uses  significant  judgment  when  making  estimates  related  to  its  stock-based
compensation,  accruals  related  to  compensation,  the  valuation  of  the  common  stock  warrants,  provisions  for  doubtful  accounts  receivable  and  excess  and
obsolete inventories, clinical trial accruals, and its reserves for sales returns and warranty costs. Management bases its estimates on historical experience and
on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the
carrying values of assets and liabilities that are not readily apparent from other sources. Although these estimates are based on the Company’s knowledge of
current events and actions it may undertake in the future, actual results may ultimately materially differ from these estimates and assumptions.

F- 10

 
 
 
 
 
 
 
 
 
 
 
 
 
Fair Value of Financial Instruments

The Company has evaluated the estimated fair value of its financial instruments as of December 31, 2021 and 2020. Financial instruments consist of
cash and cash equivalents, accounts receivable and payable, and other current liabilities and borrowings. The carrying amounts of cash and cash equivalents,
accounts receivable and payable, and other current liabilities approximate their respective fair values because of the short-term nature of those instruments.
Based upon the borrowing terms and conditions currently available to the Company, the carrying values of the borrowings approximate their fair value.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less at the time of purchase to be cash equivalents.
Cash equivalents are considered available-for-sale marketable securities and are recorded at fair value, based on quoted market prices. As of December 31,
2021 and 2020, the Company’s cash equivalents are entirely comprised of investments in money market funds. Any related unrealized gains and losses are
recorded in other comprehensive income (loss) and included as a separate component of stockholders’ equity. There were no unrealized gains and losses as of
December 31, 2021  and  2020.  Any  realized  gains  and  losses  and  interest  and  dividends  on  available-for-sale  securities  are  included  in  interest  income  or
expense and computed using the specific identification cost method.

Concentration of Credit Risk, and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents and accounts receivable to the extent of

the amounts recorded on the balance sheets.

The Company’s policy is to invest in cash and cash equivalents, consisting of money market funds. These financial instruments are held in Company
accounts at one financial institution. The counterparties to the agreements relating to the Company’s investments consist of financial institutions of high credit
standing. The Company provides for uncollectible amounts when specific credit problems arise. Management’s estimates for uncollectible amounts have been
adequate, and management believes that all significant credit risks have been identified at December 31, 2021 and 2020.

The  Company’s  accounts  receivable  are  due  from  a  variety  of  healthcare  organizations  in  the  United  States  and  select  international  markets.  At
December 31, 2021 and 2020, there was one customer that represented 21% and 14% of accounts receivable. For the year ended December 31, 2021, there
was one  customer  that  represented  10%  of  revenues.  For  the  year  ended  December  31,  2020,  there  were  no  customers  that  represented  10%  or  more  of
revenues.  Disruption  of  sales  orders  or  a  deterioration  of  financial  condition  of  its  customers  would  have  a  negative  impact  on  the  Company’s  financial
position and results of operations.

The  Company  manufactures  its  commercial  products  in-house,  including  the  Pantheris  and  Ocelot  family  of  catheters.  Certain  of  the  Company’s
product components and sub-assemblies are manufactured by sole suppliers, including internally. Disruption in component or sub-assembly supply from these
manufacturers or from in-house production would have a negative impact on the Company’s financial position and results of operations.

The Company is subject to certain risks, including that its devices may not be approved or cleared for marketing by governmental authorities or be
successfully marketed. There can be no assurance that the Company’s products will achieve widespread adoption in the marketplace, nor can there be any
assurance that existing devices or any future devices can be developed or manufactured at an acceptable cost and with appropriate performance characteristics.
The  Company  is  also  subject  to  risks  common  to  companies  in  the  medical  device  industry,  including,  but  not  limited  to,  new  technological  innovations,
dependence upon third-party payors to provide adequate coverage and reimbursement, dependence on key personnel and suppliers, protection of proprietary
technology, product liability claims, and compliance with government regulations.

Existing  or  future  devices  developed  by  the  Company  may require  approvals  or  clearances  from  the  FDA  or  international  regulatory  agencies.  In
addition, in order to continue the Company’s operations, compliance with various federal and state laws is required. If the Company were denied or delayed in
receiving such approvals or clearances, it may be necessary to adjust operations to align with the Company’s currently approved portfolio. If clearance for the
products in the current portfolio were withdrawn by the FDA, this may have a material adverse impact on the Company.

Disruption of our supply chain capabilities due to trade restrictions, political instability, severe weather, natural disasters, public health crises such as
the ongoing COVID-19 pandemic, terrorism, product recalls, labor supply or stoppages, the financial or operational instability of key suppliers and carriers,
government  restrictions  or  measures,  or  other  reasons  could  impair  our  ability  to  distribute  our  products.  Many  industries,  including  our  own,  face  supply
chain  challenges  as  a  result  of  COVID-19  and  other  macroeconomic  issues,  including  reduced  freight  availability  and  increased  costs,  port  disruption,
manufacturing facility closures, labor shortages and other supply chain disruptions. To the extent we are unable to mitigate the likelihood or potential impact
of such events, there could be a material adverse effect on our operating and financial results.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best
estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance for doubtful accounts
based  upon  an  aging  of  accounts  receivable,  historical  experience,  and  management  judgment.  Accounts  receivable  balances  are  reviewed  individually  for
collectability. To date, the Company has not experienced significant credit-related losses.

Accounts receivable allowance for doubtful accounts provision and recoveries or write-offs are summarized as follows (in thousands):

Inventories  are  valued  at  the  lower  of  cost  or  net  realizable  value.  Cost  is  determined  using  the  first-in, first-out  method  for  all  inventories.  The
Company’s policy is to write down inventory that has expired or become obsolete, inventory that has a cost basis in excess of its expected net realizable value,
and inventory in excess of expected requirements. At each balance sheet date, management evaluates inventories for excess quantities, and obsolescence. This
evaluation  by  management  includes  analysis  of  historical  sales  levels  by  product,  projections  of  future  demand,  the  risk  of  technological  or  competitive
obsolescence  for  products,  general  market  conditions,  as  well  as  the  feasibility  of  reworking  or  using  excess  or  obsolete  products  or  components  in  the
production  or  assembly  of  other  products  that  are  not  obsolete  or  for  which  there  are  not  excess  quantities  in  inventory.  To  the  extent  that  management
determines there are excess or obsolete inventory, management adjusts the carrying value to estimated net realizable value. When quantities on hand exceed
sales forecasts, a write-down is recorded for such excess inventories along with a corresponding charge to cost of revenues. The estimate of excess quantities
is subjective and primarily dependent on the estimates of future demand for a particular product. Changes in assumptions of product demand could have a
significant impact on the amount of write-down recorded. Inventory used in clinical trials is expensed at the time of production and recorded as research and
development  expense.  The  cost  of  inventories  are  regularly  reviewed  against  estimated  market  value  and  record  a  lower  of  cost  or  market  reserve  for
inventories that have a cost in excess of estimated market value, which could have a material impact on the gross margin and inventory balances based on
additional write-downs to net realizable value or a benefit from inventories previously written down.

Property and Equipment

Property and equipment are recorded at cost. Repairs and maintenance costs are expensed as incurred. Depreciation and amortization are calculated
using the straight-line method over the estimated useful lives of the assets of generally three to five years. Depreciation expense includes the amortization of
assets acquired under capital leases and equipment located at customer sites. Equipment held by customers is comprised of the Lightbox consoles located at
customer sites under a lease or placement agreement. Upon execution of a lease or placement agreement, the related equipment is reclassified from inventory
to the property and equipment account. Depreciation expense for equipment held by customers is recorded as a component of cost of revenues. Leasehold
improvements  and  assets  recorded  under  capital  leases  are  amortized  using  the  straight-line  method  over  the  shorter  of  the  lease  term  or  estimated  useful
economic life of the asset.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and equipment, for impairment whenever events or changes in business circumstances
indicate that the carrying amount of the assets may not be fully recoverable. If indicators of impairment exist, an impairment loss would be recognized when
estimated  undiscounted  future  cash  flows  expected  to  result  from  the  use  of  the  asset  and  its  eventual  disposition  are  less  than  its  carrying  amount.
Impairment, if any, is measured as the amount by which the carrying amount of the long-lived asset exceeds its fair value. The Company has not recorded any
impairment of long-lived assets since inception through December 31, 2021.

Revenue Recognition

The  Company’s  revenues  are  derived  from  (1)  sale  of  Lightbox  consoles,  (2)  sale  of  disposables,  which  consist  of  catheters  and  accessories,  and
(3)  sale  of  customer  service  contracts  and  maintenance.  The  Company  sells  its  products  directly  to  hospitals  and  medical  centers  as  well  as  through
distributors. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the
rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company’s revenues
are  measured  based  on  consideration  specified  in  the  contract  with  each  customer,  net  of  any  sales  incentives  and  taxes  collected  from  customers  that  are
remitted to government authorities. For all sales, the Company uses either a signed agreement or a binding purchase order as evidence of an arrangement. The
Company’s revenue recognition policies generally result in revenue recognition at the following points:

1.

2.

3.

Lightbox console sales: Provided all other criteria for revenue recognition have been met, the Company recognizes revenue for Lightbox
console sales directly to end customers when delivery and acceptance occurs, which is defined as receipt by the Company of an executed
form that the installation process is complete.

Sales of disposables: Disposable revenues consist of sales of the Company’s catheters and accessories and are recognized when the product
has shipped, risk of loss and title has passed to the customer and collectability is reasonably assured.

Service revenue: Service contract revenue consists of preventative maintenance, upgrades, and service contracts. Service contracts are
recognized ratably over the term of the service period and maintenance contract revenue is recognized as work is performed. To date, service
revenue has been insignificant.

The  Company  offers  its  customers  the  ability  to  purchase  or  lease  the  Lightbox  console.  In  addition,  the  Company  provides  a  Lightbox  under  a
limited commercial evaluation program to allow accounts to install and utilize the Lightbox for a limited trial period. When a Lightbox is placed under a lease
agreement  or  under  a  commercial  evaluation  program,  the  Company  retains  title  to  the  equipment  and  it  remains  capitalized  on  its  balance  sheet  under
property and equipment. Depreciation expense on these placed Lightboxes is recorded to cost of revenues on a straight-line basis. The costs to maintain these
placed Lightboxes are charged to cost of revenues as incurred.

The Company evaluates its lease and commercial evaluation program agreements and accounts for these contracts under the guidance in Accounting
Standards Codification (“ASC”) 842, Leases and ASU No. 2014 09, Revenue from Contracts with Customers (Topic 606). The guidance requires arrangement
consideration to be allocated between a lease deliverable and a non-lease deliverable based upon the relative selling-price of the deliverables.

The Company assessed whether the embedded lease is an operating lease or sales-type lease. Based on the Company’s assessment of the guidance
and given that any payments under the lease agreements are dependent upon contingent future sales, it was determined that collectability of the minimum
lease payments is not  reasonably  predictable.  Accordingly,  the  Company  concluded  the  embedded  lease  did  not  meet  the  criteria  of  a  sales-type  lease  and
accounts for it as an operating lease. The Company recognizes revenue allocated to the lease as the contingent disposable product purchases are delivered and
are included in revenues within the statement of operations and comprehensive loss.

For  sales  through  distributors,  the  Company  recognizes  revenue  when  control  of  the  product  transfers  from  the  Company  to  the  distributor.  The
distributors are responsible for all marketing, sales, training and warranty in their respective territories. The standard terms and conditions contained in the
Company’s distribution agreements do not provide price protection or stock rotation rights to any of its distributors. In addition, its distributor agreements do
not allow the distributor to return or exchange products, and the distributor is obligated to pay the Company upon invoice regardless of its ability to resell the
product.

Cost of Revenues

Cost of revenues consists primarily of manufacturing overhead costs, material costs and direct labor. A significant portion of the Company’s cost of
revenues  currently  consists  of  manufacturing  overhead  costs.  These  overhead  costs  include  the  cost  of  quality  assurance,  material  procurement,  inventory
control, facilities, equipment and operations supervision and management. Cost of revenues also includes depreciation expense for the Lightboxes under lease
and evaluation agreements, product warranty costs, product written-off due to excess or obsolescence, and certain direct costs such as shipping costs.

Product Warranty Costs

The  Company  typically  offers  a  one-year  warranty  on  its  products  commencing  upon  the  transfer  of  title  and  risk  of  loss  to  the  customer.  The
Company accrues for the estimated cost of product warranties upon invoicing its customers, based on historical results. Warranty costs are reflected in the
statement of operations and comprehensive loss as a cost of revenues. The warranty obligation is affected by product failure rates, material usage and service
delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from these estimates,
revisions to the estimated warranty liability would be required. Periodically the Company assesses the adequacy of its recorded warranty liabilities and adjusts
the amounts as necessary. Warranty provisions and claims are summarized as follows (in thousands):

The Company expenses research and development costs as incurred. Research and development expenses include personnel and personnel-related
costs, costs associated with pre-clinical and clinical development activities, and costs for prototype products that are manufactured prior to market approval for
that prototype product, and internal and external costs associated with the Company’s regulatory compliance, including the costs of outside consultants and
contractors that assist in the process of submitting and maintaining regulatory filings, and overhead costs, including allocated facility and related expenses.

Clinical Trials

The Company accrues and expenses costs for its clinical trial activities performed by third parties, including clinical research organizations and other
service providers, based upon estimates of the work completed over the life of the individual study in accordance with associated agreements. The Company
determines these estimates through discussion with internal personnel and outside service providers as to progress or stage of completion of trials or services
pursuant to contracts with clinical research organizations and other service providers and the agreed-upon fee to be paid for such services.

Stock-Based Compensation

Stock-based compensation for the Company includes amortization related to all stock options, restricted stock units (“RSU”), based on the grant-date
estimated fair value. The fair value of stock options is estimated on the date of grant using the Black-Scholes option pricing model and recognized as expense
on a straight-line basis over the vesting period of the award. The Company has not granted any stock options since 2017. The Company measures the fair
value of RSUs using the closing stock price of a share of the Company’s common stock on the grant date and is recognized as expense on a straight-line basis
over the vesting period of the award. As allowed under ASU No. 2016‑09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-
Based Payment Accounting, the Company accounts for forfeitures as they occur.

Foreign Currency

The Company records net gains and losses resulting from foreign exchange transactions as a component of foreign currency exchange losses in other
income,  net.  During  the  years  ended  December  31,  2021  and  2020,  the  Company  recorded  $16,000  and  $18,000  of  foreign  currency  exchange  net
(gains)/losses, respectively.

Income Taxes

The Company utilizes the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based
on differences between financial reporting and tax reporting bases of assets and liabilities and are measured using enacted tax rates and laws that are expected
to be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts
expected to be realized. The Company’s policy is to record interest and penalties on uncertain tax positions as income tax expense when they occur. During the
years ended December 31, 2021 and 2020, the Company did not recognize accrued interest or penalties related to unrecognized tax benefits.

Net Loss per Share Attributable to Common Stockholders

Basic  net  loss  per  share  attributable  to  common  stockholders  is  computed  by  dividing  the  net  loss  attributable  to  common  stockholders  by  the
weighted average number of shares of common stock outstanding during the period, without consideration for potential dilutive common shares. Diluted net
loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholder by the weighted average number
of shares of common stock and dilutive potential shares of common stock outstanding during the period. Any common stock shares subject to repurchase are
excluded from the calculations as the continued vesting of such shares is contingent upon the holders’ continued service to the Company. As of December 31,
2021 and 2020,  there  were  no  shares  subject  to  repurchase.  Since  the  Company  was  in  a  loss  position  for  both  periods  presented,  basic  net  loss  per  share
attributable to common stockholders is the same as diluted net loss per share attributable to common stockholders as the inclusion of all potentially dilutive
common shares would have been anti-dilutive.

Net loss per share attributable to common stockholders was determined as follows (in thousands, except per share data):

Net loss applicable to common stockholders

Segment and Geographical Information

The Company operates and manages its business as one reportable and operating segment. The Company’s chief executive officer, who is the chief
operating  decision  maker,  reviews  financial  information  on  an  aggregate  basis  for  purposes  of  allocating  resources  and  evaluating  financial  performance.
Primarily all of the Company’s long-lived assets, which are comprised of property and equipment, are based in the United States. For each of the years ended
December 31, 2021 and 2020, 94% of the Company’s revenues were in the United States, based on the shipping location of the external customer.

Recent Accounting Pronouncements

Recently adopted accounting standards

In  December  2019,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  Accounting  Standards  Update  (“ASU”)  2019-12,  Income  Taxes
(Topic 740): Simplifying the Accounting for Income Taxes, which among other things, eliminates certain exceptions in the current rules regarding the approach
for intraperiod tax allocations and the methodology for calculating income taxes in an interim period, and clarifies the accounting for transactions that result in
a  step-up  in  the  tax  basis  of  goodwill.  The  standard  was  adopted  by  the  Company  on  January 1, 2021. The  adoption  of  this  new  standard  did  not  have  a
material impact on the Company’s financial statements.

Recent accounting standards not yet adopted

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—
Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which among other
things, simplifies the accounting models for the allocation of proceeds attributable to the issuance of a convertible debt instrument.  As a result, after adopting
the ASU’s guidance, entities will not separately present in equity an embedded conversion feature in such debt. Instead, they will account for a convertible
debt  instrument  wholly  as  debt,  and  for  convertible  preferred  stock  wholly  as  preferred  stock  (i.e.,  as  a  single  unit  of  account),  unless  (i)  a  convertible
instrument contains features that require bifurcation as a derivative under ASC 815 or (ii) a convertible debt instrument was issued at a substantial premium.
The standard becomes effective for the Company in the first quarter of 2024 and early adoption is permitted.  This new standard is not expected to have a
material impact on the Company’s financial statements.

In May 2021, ASU No. 2021-04, Issuer’s Accounting for Certain Modifications of Exchanges of Freestanding Equity-Classified Written Call Options
was  issued  to  clarify  the  accounting  for  modifications  or  exchanges  of  freestanding  equity-classified  written  call  options,  such  was  warrants,  that  remain
equity  classified  after  modification  or  exchange.  This  ASU  became  effective  for  the  Company  on  January 1, 2022 and  is  not  expected  to  have  a  material
impact on the financial statements.

3. Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount
that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based
measurement  that  should  be  determined  based  on  assumptions  that  market  participants  would  use  in  pricing  an  asset  or  a  liability.  A  three-tier  fair  value
hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, such as quoted prices for similar
assets  or  liabilities;  quoted  prices  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 the 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.

As of December 31, 2021 and 2020, the Company’s cash equivalents were all categorized as Level 1 and consisted of money market funds. As of
December 31, 2021 and 2020,  there  were  no  financial  assets  and  liabilities  categorized  as  Level  2 or Level 3.  There  were  no  transfers  between  fair  value
hierarchy levels during the years ended December 31, 2021 and 2020.

In January 2022, the Company issued warrants to purchase common stock categorized as Level 3.

Property and equipment include certain equipment that is leased to customers and located at customer premises. The Company retains the ownership
of  the  equipment  held  for  evaluation  and  has  the  right  to  remove  the  equipment  if  it  is  not  being  utilized  according  to  expectations.  Depreciation  expense
relating to the leased equipment held by customers of $539,000 and $629,000 was recorded in cost of revenues during the years ended December 31, 2021 and
2020,  respectively.  This  leased  equipment  was  fully  depreciated  as  of  December 31, 2021. The  net  book  value  of  this  leased  equipment  was  $518,000  at

On September 22, 2015, the Company entered into a Term Loan Agreement, as amended (the “Loan Agreement”) with CRG under which, subject to
certain  conditions,  the  Company  had  the  right  to  borrow  up  to  $50  million  in  principal  amount  from  CRG  on  or  before  March  29,  2017.  The  Company
borrowed $30 million on September 22, 2015. The Company borrowed an additional $10 million on June 15, 2016 under the Loan Agreement.

On February 14, 2018, the Company and CRG further amended the Loan Agreement concurrent with the conversion of $38 million of the principal
amount of the senior secured term loan (plus $3.8 million in back-end fees and prepayment premium applicable thereto) into a newly authorized Series A
convertible preferred stock (see below).

On March 2, 2020, the Company entered into Amendment No. 3 to the Loan Agreement to, among other things:

●

●

●

●

extend the period that the Company can make interest payments in payment in kind (“PIK”) to June 30, 2021;

lower the Minimum Revenue Covenants to $10 million for 2020, $12 million for 2021, and $15 million for 2022;

insert certain terms to clarify that all fees, including the prepayment premium, are due if the obligations are accelerated; and

insert a new provision to make clear that to the extent the Company divides its assets/liabilities into divisions, such assets/liabilities will
be treated as transferred to a third party.

On May 12, 2020, the Company entered into Amendment No. 4 to the Loan Agreement to, among other things:

●

●

grant to the Company the right to optionally prepay in whole or in part the outstanding principal amount of the Loans for the Redemption
Price, subject to certain conditions; and

waive the Company’s requirement to comply with the Minimum Revenue Covenant for 2020.

On January 22, 2021, the Company entered into Amendment No. 5 to the Loan Agreement to, among other things:

●

●

●

●

●

extend the maturity date of the Loan Agreement from June 30, 2023 to December 31, 2025;

extend the interest only payment period and the period that the Company can make interest payments in PIK to December 31, 2023;

lower the Minimum Revenue Covenants to $8 million and $10 million for 2021 and 2022, respectively and establish revenue covenants of
$12 million for 2023; $14.5 million for 2024, and $17 million for 2025;

change the date under the on-going stand-alone representation regarding no Material Adverse Change to December 31, 2020;

and amend the on-going stand-alone representation and stand-alone event of default regarding “Material Adverse Change” such that any
adverse change in or effect upon the revenue of the Company and its subsidiaries due to the outbreak of COVID-19 will not constitute a
Material Adverse Change

Under the amended Loan Agreement, no cash payments for either principal or interest are due until the first quarter of 2024. The interest will be
accrued and included in the debt balance based (to the extent not paid) on principal amounts outstanding at the beginning of the quarter at an interest rate of
12.5%. Beginning in the first quarter of 2024, the Company will be required to make quarterly principal payments (in addition to the interest) of $1.9 million
with total principal payments of $7.5 million in 2024 and $7.5 million in 2025. The maturity date of the Loan is December 31, 2025.

The  Company  may  voluntarily  prepay  the  borrowings  in  full,  with  a  prepayment  premium  beginning  at  5.0%  and  declining  by  1.0%  annually
thereafter, with no premium being payable if prepayment occurs after seven and half years of the loan. Each tranche of borrowing required the payment, on the
borrowing date, of a financing fee equal to 1.5% of the borrowed loan principal, which is recorded as a discount to the debt. In addition, a facility fee equal to
15.0% of the amounts borrowed plus any payment-in-kind (“PIK”) is to be payable at the end of the term or when the borrowings are repaid in full. A long-
term liability is being accreted using the effective interest method for the facility fee over the term of the Loan Agreement with a corresponding discount to the
debt. The borrowings are collateralized by a security interest in substantially all of the Company’s assets.

The Loan Agreement requires that the Company adheres to certain affirmative and negative covenants, including financial reporting requirements,
certain minimum financial covenants for pre-specified liquidity and revenue requirements and a prohibition against the incurrence of indebtedness, or creation
of  additional  liens,  other  than  as  specifically  permitted  by  the  terms  of  the  Loan  Agreement.  In  particular,  the  covenants  of  the  amended  Loan  Agreement
included a covenant that the Company maintain a minimum of $3.5 million of cash and certain cash equivalents, and the Company has to achieve certain
minimum revenues. If the Company fails to meet the applicable minimum revenue target in any calendar year, the Loan Agreement provides the Company
with a cure right if it prepays a portion of the outstanding principal equal to 2.0 times the revenue shortfall. In addition, the Loan Agreement prohibits the
payment of cash dividends on the Company’s capital stock and also places restrictions on mergers, sales of assets, investments, incurrence of liens, incurrence
of  indebtedness  and  transactions  with  affiliates.  CRG  may accelerate  the  payment  terms  of  the  Loan  Agreement  upon  the  occurrence  of  certain  events  of
default set forth therein, which include the failure of the Company to make timely payments of amounts due under the Loan Agreement, the failure of the
Company to adhere to the covenants set forth in the Loan Agreement, the insolvency of the Company or upon the occurrence of a material adverse change.

As of December 31, 2021, the Company was in compliance with all applicable covenants under the Loan Agreement.

In connection with drawdowns under the Loan Agreement, the Company recorded aggregate debt discounts of $1.3 million as contra-debt. The debt
discounts are being amortized as non-cash interest expense using the effective interest method over the term of the Loan Agreement. As of December 31, 2021
and 2020, the balance of the aggregate debt discount was approximately $333,000 and $418,000, respectively. The Company’s interest expense associated
with  the  amortization  of  debt  discount  was  approximately  $86,000  and  $169,000  during  the  years  ended  December  31,  2021  and 2020,  respectively.  The
Company incurred total interest expense of approximately $1.6 million and $1.5 million during the years ended December 31, 2021 and 2020, respectively. 

As of December 31, 2021, all of the CRG borrowings and associated aggregate debt discount were classified as non-current.

Paycheck Protection Program

On April 23, 2020, the Company received loan proceeds of $2.3 million (the “PPP Loan”) pursuant to the PPP under the CARES Act.

The Loan, which was in the form of a promissory note, dated April 20, 2020 (the “Promissory Note”), between the Company and Silicon Valley Bank
(“SVB”) as the lender, was set to mature on April 20, 2022 and bore interest at a fixed rate of 1% per annum, payable monthly commencing six months from
the date of the Loan. The Company may voluntarily prepay the borrowings in full with no associated penalty or premium.

The PPP was administered by the U.S. Small Business Administration (the “SBA”). The SBA was given the authority under the PPP to forgive loans
if all employees were kept on the payroll for a required period and the loan proceeds were used for payroll, rent and utilities. The Company applied for debt
forgiveness in December 2020.

On April 17, 2021, the Company was notified by SVB that its PPP Loan had been fully forgiven by the SBA and that there was no remaining balance
on the PPP Loan. The Company recorded the forgiveness as other income in April 2021 in the amount of $2.4 million, of which approximately $23,000 was
accrued interest.

For the years ended December 31, 2021 and 2020, the Company incurred interest expense of approximately $7,000 and $16,000, respectively, related

to the PPP Loan.

8. Leases

The Company’s operating lease obligations primarily consist of leased office, laboratory, and manufacturing space under a non-cancelable operating
lease. In addition to the minimum future lease commitments presented below, the lease requires the Company to pay property taxes, insurance, maintenance,
and repair costs. The lease includes a rent holiday concession and escalation clauses for increased rent over the lease term. Rent expense is recognized using
the straight-line method over the term of the lease. The Company records deferred rent calculated as the difference between rent expense and the cash rental
payments.

The  lease  will  expire  on  November  30,  2024.  The  Company  is  obligated  to  pay  approximately  $5.8  million  in  base  rent  payments  through

November 2024, beginning on December 1, 2019. The weighted average remaining lease term as of December 31, 2021 is 2.9 years.

The operating lease was included on the balance sheet at the present value of the future base payments discounted at a 6.5% discount rate using the
rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments in a similar
economic environment as the lease does provide an implicit rate.

Rent  expense  for  both  the  years  ended  December  31,  2021  and  2020  was  approximately  $1.3  million.  Our  variable  expenses  for  both  the  years  ended
December 31, 2021 and 2020 was approximately $0.2 million. Operating right-of-use asset amortization for the year ended December 31, 2021 and 2020 was
approximately $1.0 million and $964,000, respectively. Due to payments being made in excess of operating lease expense recognized, the Company recorded
approximately $158,000 and $291,000 as prepaid rent included in other assets on the balance sheet as of December 31, 2021 and 2020, respectively.

The  following  table  presents  the  future  operating  lease  payments  and  leasehold  liability  included  on  the  balance  sheet  related  to  the  Company’s

Purchase obligations consist of agreements to purchase goods and services entered into in the ordinary course of business. The Company had non-
cancelable commitments to suppliers for purchases totaling approximately $1.4 million as of December 31, 2021. The majority of this amount is related to
commitments to purchase inventory components for our various product lines.

Indemnification

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and may
provide for indemnification of the counterparty. The Company’s exposure under these agreements is unknown because it involves claims that may be made
against it in the future, but have not yet been made. To date, the Company has not been subject to any claims or been required to defend any action related to
its indemnification obligations.

The Company indemnifies each of its directors and officers for certain events or occurrences, subject to certain limits, while the director is or was
serving at the Company’s request in such capacity, as permitted under Delaware law and in accordance with its certificate of incorporation and bylaws. The
term  of  the  indemnification  period  lasts  as  long  as  a  director  may be  subject  to  any  proceeding  arising  out  of  acts  or  omissions  of  such  director  in  such
capacity.  The  maximum  amount  of  potential  future  indemnification  is  unlimited;  however,  the  Company  currently  holds  director  liability  insurance.  This
insurance allows the transfer of risk associated with the Company’s exposure and may enable it to recover a portion of any future amounts paid. The Company
believes that the fair value of these indemnification obligations is minimal. Accordingly, it has not recognized any liabilities relating to these obligations for
any period presented.

Legal Proceedings

The  Company  is  not  currently  involved  in  any  pending  legal  proceedings  that  it  believes  could  have  a  material  adverse  effect  on  our  financial
condition, results of operations or cash flows. From time to time, the Company may be involved in legal proceedings or investigations, which could harm our
reputation, business and financial condition and divert the attention of our management from the operation of our business.

10. Stockholders’ Equity

Convertible Preferred Stock

As of December 31, 2021, the Company’s certificate of incorporation, as amended and restated, authorizes the Company to issue up to 5,000,000
shares of convertible preferred stock with $0.001 par value per share, of which 56,451 shares were issued and outstanding. As of December 31, 2020, there
were 52,369 shares of convertible preferred stock issued and outstanding.

Series A Convertible Preferred Stock

The holders of Series A preferred stock are entitled to receive annual accruing dividends at a rate of 8%, payable in additional shares of Series A
preferred stock or cash, at the Company’s option. The shares of Series A preferred stock have a liquidation preference of $1,000 per share, no voting rights and
rank senior to all other classes and series of the Company’s equity in terms of repayment and certain other rights. During the years ended December 31, 2021
and 2020, 4,175 and 3,866 additional shares, respectively, were issued to CRG as payment of dividends. As of December 31, 2021, 56,366 shares of Series A
preferred stock were outstanding, which are currently convertible into shares of the Company’s common stock at $400 per share. The Series A preferred stock
annual dividends of approximately $4.2 million and $3.9 million during the years ended December 31, 2021 and 2020, respectively.

Series B Convertible Preferred Stock

The Series B preferred stock has a liquidation preference of $0.001 per share, full ratchet price based anti-dilution protection, has no voting rights and
is subject to certain ownership limitations. The Series B preferred stock is immediately convertible at the option of the holder, has no stated maturity, and does
not pay regularly stated dividends or interest. During the year ended December 31, 2021, 93 of these shares converted into 18,600 shares of common stock. As
of December 31, 2021, 85 shares of Series B preferred stock remained outstanding, which are currently convertible into shares of the Company’s common
stock at $5 per share.

Series D Convertible Preferred Stock

On January 14, 2022, the Company entered into a security purchase agreement with several institutional investors, pursuant to which the Company
agreed  to  sell  and  issue,  in  a  registered  direct  offering  (  “January  2022  offering”),  an  aggregate  of  7,600  shares  of  the  Company’s  Series  D  convertible
preferred stock, par value $0.001 per share at an offering price of $1,000 per share. Concurrently, the Company agreed to issue to these investors warrants to
purchase  up  to  an  aggregate  of  807,500  shares  of  the  Company’s  common  stock  (the  “Common  Warrants”).  The  shares  of  Series  D  Preferred  Stock  has  a
stated value of $1,000 per share and are convertible into an aggregate of 950,000 shares of common stock at a conversion price of $8.00 per share.

The  Series  D  preferred  stock  has  no  voting  rights,  other  than  the  right  to  vote  as  a  class  on  certain  matters,  except  that  each  share  of  Series  D
preferred stock has the right to cast 37,500 votes per share of Series D preferred stock on a one-time proposal (the “Proposal”) to amend to the Company’s
Amended and Restated Certificate of Incorporation, as amended (the “Charter”) to effect a reverse split of the outstanding shares of the Company’s common
stock  at  a  ratio  between  1-for-5  and  1-for-20  (the  “Reverse  Split  Amendment”)  (the  “Supermajority  Voting  Rights”);  provided,  that  the  votes  cast  by  the
holders  of  the  Series  D  preferred  stock  must  be  counted  by  the  Company  in  the  same  proportion  as  the  aggregate  shares  of  common  stock  voted  on  the
Proposal. Because the Proposal was approved by our stockholders at the special meeting held on March 11, 2022, the Series D preferred stock no longer has
Supermajority Voting Rights.

F- 21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The holders of the Series D preferred stock are entitled to dividends, on an as-if converted basis, equal to dividends actually paid, if any, on shares of
Common Stock. The Series D preferred stock is convertible into shares of common stock at a conversion price of $8.00 per share, as adjusted for the most
recent  reverse  stock  split.  The  conversion  price  can  be  adjusted  pursuant  to  the  Certificate  of  Designation  for  stock  dividends  and  stock  splits,  subsequent
rights offerings, pro rata distributions of dividends or the occurrence of a fundamental transaction (as defined in the Certificate of Designation). The Series D
preferred stock can be converted at the option of the holders at any time. In addition, subject to the satisfaction of certain conditions, we may cause the holders
of the Series D preferred stock to convert their shares of Series D preferred stock; provided, that shares of Series D preferred stock cannot be converted to
common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election by such holder prior to the issuance of any shares of
Series D preferred stock, 9.99%) of our outstanding common stock. A holder of Series D preferred stock may, upon notice to us, increase or decrease such
beneficial ownership limitation, but not in excess of 9.99%.

Common Stock

At December 31, 2021,  the  Company’s  certificate  of  incorporation,  as  amended  and  restated,  authorizes  the  Company  to  issue  up  to  100,000,000

Pursuant to the purchase agreement entered into on January 14, 2022, the Company issued the Common Warrants to purchase up to an aggregate of
807,500  shares  of  the  Company’s  common  stock  at  an  exercise  price  of  $9.60  per  share  and  become  exercisable  beginning  July  14,  2022.  The  Common
Warrants will expire five years following the time they become exercisable, or July 14, 2027. The exercise price and the number of shares of common stock
issuable upon exercise of each common warrant is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits,
stock combinations, reclassifications or similar events affecting the common stock. In addition, in certain circumstances, upon a fundamental transaction, a
holder of Common Warrants will be entitled to receive, upon exercise, the kind and amount of securities, cash or other property that such holder would have
received had they exercised the Common Warrants immediately prior to the fundamental transaction.

The Common Warrants can be exercised at the option of the holders at any time after they become exercisable provided that shares of the Common
Warrants cannot be exercised into common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election by such holder prior to
the  issuance  of  any  shares  of  Common  Warrants,  9.99%)  of  the  Company’s  outstanding  common  stock  immediately  after  giving  effect  to  the  exercise.  A
holder of the Common Warrants may, upon notice to the Company, increase or decrease such beneficial ownership limitation, but not in excess of 9.99%.

The Company also issued to the placement agent of the January 2022 Offering warrants to purchase up to an aggregate of 66,500 shares of common
stock (the “Placement Agent Warrants”). The Placement Agent Warrants are subject to the same terms as the Common Warrants, except that the Placement
Agent  Warrants  have  an  exercise  price  of  $10.00  per  share  and  a  term  of  five  years  from  the  commencement  of  the  sales  pursuant  to  the  January  2022
Offering, or January 12, 2027. 

During the year ended December 31, 2021, a total of 1,083,091 warrant shares to purchase a total of up to 5,416 shares of common stock that issued
in  connection  with  the  July  2018  financing  expired  without  being  exercised.  As  of  December  31,  2021  and  2020,  warrants  to  purchase  an  aggregate  of
1,006,285 and 137,701 shares of common stock, respectively, were outstanding.

Stock Plans

In January 2015, the Board of Directors adopted and the Company’s stockholders approved the 2015 Equity Incentive Plan (“2015 Plan”). The 2015
Plan  provides  for  the  grant  of  incentive  stock  options  (“ISOs”)  to  employees  and  for  the  grant  of  non-statutory  stock  options  (“NSOs”),  restricted  stock,
restricted  stock  units  (“RSUs”),  stock  appreciation  rights,  performance  units  and  performance  shares  to  employees,  directors  and  consultants.  The  shares
reserved for issuance under the 2015 Plan includes share awards granted under the prior equity incentive plan that expire or terminate without having been
exercised in full or that are forfeited or repurchased. In addition, the number of shares available for issuance under the 2015 Plan includes an automatic annual
increase  on  the  first  day  of  each  fiscal  year  equal  to  the  lesser  of  211  shares,  5.0%  of  the  outstanding  shares  of  common  stock  as  of  the  last  day  of  the
immediately preceding fiscal year or an amount as determined by the Board of Directors. As of December 31, 2021, 8,480 shares were available for grant
under the 2015 Plan.

Pursuant to the 2015 Plan, ISOs and NSOs may be granted with exercise prices at not less than 100% of the fair value of the common stock on the
date of grant and the exercise price of ISOs granted to a stockholder, who, at the time of grant, owns stock representing more than 10% of the voting power of
all classes of the stock of the Company, shall be not less than 110% of the fair market value per share of common stock on the date of grant. The Company’s
Board of Directors determines the vesting schedule of the options. Options granted generally vest over four years and expire ten years from the date of grant.

There were no options granted or exercised during either of the years ended December 31, 2021 or 2020. For the years ended December 31, 2021 and
2020,  stock-based  compensation  expense  recognized  associated  with  stock  options  vesting  was  approximately  $4,000  and  $58,000,  respectively.  As  of 
December 31, 2021, there is no remaining unamortized stock-based compensation expense associated with unvested stock options. Because of the Company’s
net operating losses, the Company did not realize any tax benefits from share-based payment arrangements for the years ended December 31, 2021 and 2020.

As  of    December  31,  2021,  there  was  approximately  $0.2  million  of  remaining  unamortized  stock-based  compensation  expense  associated  with
RSUs, which will be expensed over a weighted average remaining service period of less than one year. The outstanding non-vested and expected to vest RSUs
at December 31, 2021 have an aggregate fair value of approximately $0.1 million. The Company used the closing market price of $9 per share at December
31, 2021 to determine the aggregate fair value for the RSUs outstanding at that date. For the years ended December 31, 2021 and 2020, the fair value of RSUs
vested  was  approximately  $273,000  and  $135,000,  respectively.  For  the  years  ended  December  31,  2021  and  2020,  stock-based  compensation  expense
recognized associated with the vesting of RSUs was approximately $1.0 million and $1.5 million, respectively.

2018 Officer and Director Share Purchase Plan

On August 22, 2018, the Board of Directors of the Company approved the adoption of an Officer and Director Share Purchase Plan (“ODPP”), which
allows executive officers and directors to purchase shares of our common stock at fair market value in lieu of salary or, in the case of directors, director fees.
Eligible individuals may voluntarily participate in the ODPP by authorizing payroll deductions or, in the case of directors, deductions from director fees for
the purpose of purchasing common stock. The Board of Directors authorized 1,000 shares to be made available for purchase by officers and directors under
the ODPP. Effective on August 28, 2019 and March 10, 2020, the Board of Directors approved an additional 2,000 and 6,250 shares, respectively, to be made
available under the ODPP. There was no common stock issued under the ODPP during the year ended December 31, 2021. Common stock issued under the
ODPP during the year ended December 31, 2020 totaled 2,652 shares. As of December 31, 2021, there  were  4,609  shares  reserved  for  issuance  under  the
ODPP.

The valuation allowance increased by $4.7 million and increased by $3.4 million during the years ended December 31, 2021 and 2020, respectively.

As of December 31, 2021, the Company had approximately $334.4 million of federal and $204.8 million of state net operating loss carryforwards
available to offset future taxable income. If not utilized, the federal and state net operating loss carryforwards begin to expire in 2027 and 2024, respectively.
Out of the Federal net operating loss carryforwards, $76.9 million were generated post  December 31, 2017 and have no expiration.

As  of  December  31,  2021,  the  Company  also  had  approximately  $3.9  million  of  research  and  development  tax  credit  carryforwards  available  to
reduce future taxable income, if any, for both federal and California purposes. The federal credit carryforwards expire beginning in 2027, and the California
research credits do not expire and may be carried forward indefinitely.

The Company's ability to utilize the net operating loss and tax credit carryforwards in the future may be subject to substantial restrictions in the event
of  past  or  future  ownership  changes  as  defined  in  Section  382  of  the  Internal  Revenue  Code  and  similar  state  tax  laws.  In  the  event  the  Company  should
experience an ownership change, as defined, utilization of the Company's net operating loss carryforwards and tax credits could be limited.

The  Company  evaluates  tax  positions  for  recognition  using  a  more-likely-than-not  recognition  threshold,  and  those  tax  positions  eligible  for
recognition  are  measured  as  the  largest  amount  of  tax  benefit  that  is  greater  than  50%  likely  of  being  realized  upon  the  effective  settlement  with  a  taxing
authority that has full knowledge of all relevant information.

As  of  December  31,  2021,  all  unrecognized  tax  benefits  would  be  subject  to  a  full  valuation  allowance,  if  recognized,  and  would  not  affect  the

Company’s tax rate.

The  Company  does  not  anticipate  that  the  total  amounts  of  unrecognized  tax  benefits  will  significantly  increase  or  decrease  in  the  next  twelve

months.

The  Company's  policy  is  to  include  interest  and  penalties  related  to  unrecognized  tax  benefits  within  its  provision  for  income  taxes.  Due  to  the
Company's net operating loss position, the Company has not recorded an accrual for interest or penalties related to uncertain tax positions for the years ended
December 31, 2021 or 2020.

The Consolidated Appropriations Act, 2021  (the  “Act”)  was  enacted  in  the  United  States  on  December 27, 2020. The  Act  enhances  and  expands

certain provisions of the CARES Act, which among other things, allows deductions for expenses paid with proceeds from the PPP Loan.

13. 401(k) Plan

The Company has a qualified retirement plan under section 401(k) of the Internal Revenue Code (“IRC”) under which participants may contribute up
to  99%  of  their  eligible  compensation,  subject  to  maximum  deferral  limits  specified  by  the  IRC.  The  Company  may  make  a  discretionary  matching
contribution to the 401(k) plan, and may make a discretionary employer contribution to each eligible employee each year. To date, the Company has made no
contributions to the 401(k) plan.

14. Subsequent Events

On March 15, 2022, certain holders of Series D preferred stock opted to convert their Series D preferred stock into common stock. A total of 5,200
shares of Series D preferred stock were converted resulting in the issuance of an aggregate of 650,000 shares of common stock. After giving effect to these
aforementioned conversions, there remains 2,400 shares of Series D preferred stock, which if converted, would result in the issuance of 300,000 shares of
common stock.
