Overview

PART I

We  are  a  medical  aesthetics  company  committed  to  making  a  difference  in  patients’  lives  by  enhancing  their  body
image, growing their self ‑esteem and restoring their confidence. We were founded to provide greater choice to board ‑certified
plastic  surgeons  and  patients  in  need  of  medical  aesthetics  products.  We  have  developed  a  broad  portfolio  of  products  with
technologically differentiated characteristics, supported by independent laboratory testing and strong clinical trial outcomes. We
sell  our  breast  implants  and  breast  tissue  expanders,  or  Breast  Products,  exclusively  to  board  ‑certified  and  board  ‑admissible
plastic surgeons and tailor our customer service offerings to their specific needs, which we believe helps secure their loya lty and
confidence.

Our  primary  products  are  silicone  gel  breast  implants  for  use  in  breast  augmentation  and  breast  reconstruction
procedures, which we offer in over 195 variations of shapes, sizes , fill volumes and textures. Our breast implants are primarily
used in elective procedures which are generally performed on a cash ‑pay basis. Many of our breast implants incorporate one or
more differentiated technologies, including a proprietary high ‑strength, cohesive silicone gel and proprietary texturing branded
TRUE Texture ® .  Our  breast  implants  offer  a  desired  balance  between  strength,  shape  retention  and  softness  due  to  the  high
‑strength, cohesive silicone gel used in our manufacturing process. TRUE Texture ® provides texturing on the implant shell that
is designed to reduce the incidence of malposition, rotation and capsular contracture. We also offer breast tissue expanders and a
range  of  other  aesthetic  and  specialty  products.  We  do  not  have  any  patents  or  patent  applications,  but  rely  on  trade  secrets,
proprietary know ‑how and regulatory barriers to protect our products and technologies.

Our  breast  implants  were  approved  by  the  U.S.  Food  and  Drug  Administration,  or  FDA,  in  2012,  based  on  data  we
collected  from  our  ongoing,  long  ‑term  clinical  trial  ,  or  the  Study,  of  our  breast  implants  in  1,788  women  across  36
investigational sites in the United States , which included 3,506 implants (approximately 53% of which were smooth and 47% of
which  were  textured)  .  Our  clinical  trial  is  the  largest  prospective,  long  ‑term  safety  and  effectiveness  pivotal  study  of  breast
implants in the United States and included the largest magnetic resonance imaging, or MRI, cohort with 571 patients .   The MRI
cohort  is  a  subset  of  study  patients  that  underwent  regular  MRI  screenings  in  addition  to  the  other  aspects  of  the  clinical  trial
protocol prior to FDA approval. Post-approval, all patients in the Study are subject to serial MRI screening as part of the clinical
protocol .   The clinical data we collected over a n   eight ‑year follow ‑up period demonstrated rupture rates, capsular contracture
rates and reoperation rates that were comparable to or better than those of our competitors, at similar time points . In addition to
our pivotal study, our clinical data is supported by our Continued Access Study of 2,497 women in the United States. We have
also commissioned a number of bench trials run by independent laboratories that we believe further demonstrate the advantages
of our breast implants over those of our competitors.

We sell our Breast Products exclusively to board ‑certified and board ‑admissible plastic surgeons, as determined by the
American  Board  of  Plastic  Surgery,  who  we  refer  to  as  Plastic  Surgeons.  These  surgeons  have  completed  the  extensive  multi
‑year  plastic  surgery  residency  training  required  by  the  American  Board  of  Plastic  Surgery.  While  aesthetic  procedures  are
performed  by  a  wide  range  of  medical  professionals,  including  dermatologists,  otolaryngologists,  obstetricians,  gynecologists,
dentists and other specialists, the majority of aesthetic surgical procedures are performed by Plastic Surgeons. Plastic Surgeons
are thought leaders in the medical aesthetics industry. According to the American Society of Plastic Surgeons, or ASPS, there are
approximately  6,400  board  ‑certified  plastic  surgeons  in  the  United  States.  We  seek  to  provide  Plastic  Surgeons  with
differentiated  services,  including  enhanced  customer  service  offerings,  a  ten  ‑year  limited  warranty  that  is  the  best  ‑in  ‑the
‑industry  based  on  providing  patients  with  the  largest  cash  reimbursement  for  certain  out  ‑of ‑pocket  costs  related  to  revision
surgeries  in  a  covered  event;  a  lifetime  no  ‑charge  implant  replacement  program  for  covered  ruptures;  and  our  industry  ‑first
CapCon Care Program, or C3 Program, through which we offer no ‑charge replacement implants to breast augmentation patients
who experience capsular contracture within the first five years after implantation with our smooth or textured breast implants.

We commenced sales of our breast implants in the United States in the second quarter of 2012. Our net sales were $38.1
 million, $44.7  million and $35.2  million for the years ended December 31, 2015 ,   2014 and 2013 , respectively. Our net loss
was $41.2  million, $5.8  million and $19.1  million for the years ended December 31, 2015 ,   2014 and 2013 , respectively.

Between October 9, 2015 and March 1, 2016, we voluntarily suspended the sale of all Sientra devices manufactured by
our  sole  manufacturer  and  supplier  Silimed  Industria  de  Implantes  Ltda.  (formerly,  Silimed-Silicone  e  Instrumental  Medico-
Cirugio e Hospitalar Ltda.), or Silimed , due to the suspension of Silimed’s CE certificate by TUV SUD, Silimed’s notified body
under EU regulations, followed by Brazilian regulatory inquiries and a temporary suspension by the Brazilian regulatory agency
ANVISA and the Department of the Secretary of State of Rio de Janeiro of the manufacturing and shipment of all medical devices
made by Silimed, and recommended that plastic surgeons discontinue implanting the devices until further notice. As of March 1,
2016,  after  ongoing  discussions  with  the  FDA and  our own review  of the  matter  with  the  assistance  of  independent  experts  in
quality management systems, Good Manufacturing Practices, or GMP, and data-based risk assessment, we lifted this temporary
hold on sale and also sent a letter to our Plastic Surgeons informing them of our market re-entry plans. In addition, on October 22,
2015, there was a fire in the manufacturing building where Silimed primarily manufactures our breast implants. We are working
with  Silimed  to  seek  clarity  as  to  the  near  and  long-term  capabilities  of  Silimed’s  manufacturing  operations.  See “Business —
Manufacturing and Quality Assurance” and “Risk Factors — Risks Relating to Our Business and Our Industry ” for further detail.

Our Market

The overall market for medical aesthetic procedures is significant, and awareness and acceptance of these procedures is
growing in the United States. According to the American Society for Aesthetic Plastic Surgery, or ASAPS, in 201 4 , consumers
in the United States spent approximately $12.4 billion on aesthetic procedures overall, including both surgical and non ‑invasive
cosmetic treatment s. Of this amount, more than $7.5  billion was spent on aesthetic surgical procedures.

Breast augmentation surgery remains the leading aesthetic surgical procedure by dollars and number of procedures in the
United States. According to ASAPS, over 287 ,000 primary breast augmentation procedures and 72 ,000 revision augmentation
procedures  were  perfor  med  in  the  United  States  in  2014  .  These  procedures  provide  cosmetic  solutions  generally  to  enhance
breast  size  and  shape,  correct  breast  asymmetries  or  help  restore  fullness  after  breastfeeding.  For  breast  reconstruction,  ASPS
estimates that approximately 102 ,000 procedures were performed in the United States in 201 4 . These procedures are a surgical
solution generally used to restore a breast to near normal shape and appearance following a mastectomy and typically utilize a
breast tissue expander prior to implantation of a breast implant. Based on the number of procedures reported by ASAPS and by
ASPS, and our estimates of average selling price, implant mix and implants per procedure, we estimate that the U.S. market for
breast implants and breast tissue expanders exceeded $6 30  million in 201 4 .  

Our Opportunity

We believe a significant opportunity exists in the U.S. marketplace due to the high barriers to entry in the U.S. breast

implant market and the historical lack of product and service innovation for Plastic Surgeons.

For more than 20 years prior to the FDA approval of our breast implants in 2012, only two companies manufactured and
distributed breast implants in the United States. We believe that this market concentration is largely a result of the considerable
costs  and  risks  associated  with  the  lengthy  regulatory  approval  process  required  by  the  FDA,  which  has  created  a  significant
barrier to entry in the U.S. breast implant market. All new breast implants require pre ‑market approval, or PMA, from the FDA
before  they  may  be  marketed  in  the  United  States.  The  PMA  application  process  is  lengthy  and  uncertain,  and  the  PMA
application must be supported by valid scientific evidence, which typically requires long ‑term follow ‑up of a large number of
enrolled  patients,  as  well  as  extensive  technical,  pre  ‑clinical,  clinical  and  manufacturing  data  to  demonstrate  safety  and
effectiveness. At present, we are not aware of any ongoing clinical studies in the United States for silicone  gel breast implants
other than those post ‑approval studies being performed by us and our two U.S. competitors. We believe that in the near term, it is
likely  that  the  companies  currently  providing  silicone  gel  breast  implants  in  the  United  States  will  continue  to  be  the  only
companies servicing the U.S. silicone breast implant   market.

We  believe  the  rigorous  FDA  approval  process  and  the  existence  of  only  two  competitors  in  the  U.S.  market  have
historically  contributed  to  a  lack  of  technological  innovation  in  the  U.S.  breast  implant  industry  resulting  in  limited  product
choices. Until the FDA approval of our breast implants in 2012 , surgeons in the United States were only able to purchase basic
round  breast  implants  from  our  two  U.S.  competitors,  while  surgeons  outside  of  the  United  States  were  able  to  purchase
technologically ‑advanced round and anatomically ‑shaped breast implants.

Our Competitive Strengths

We  believe  that  we  are  well  positioned  to  take  advantage  of  opportunities  afforded  by  current  market  dynamics.  By
focusing on products with technologically differentiated characteristics, demonstrating strong clinical data, offering more product
choice and providing services tailored specifically to the needs of Plastic Surgeons, we believe we can continue to enhance our
position in the breast implant market. Our competitive strengths include:

Differentiated 
silicone 
gel 
and 
texturing 
technologies.
  We  incorporate  differentiated  technologies  into  our  breast
implants, including a proprietary high ‑strength, cohesive silicone gel and proprietary texturing branded TRUE Texture ® . Our
breast implants offer a desired balance between strength, shape retention and softness due to the high-strength, cohesive silicone
gel used in our manufacturing process. In addition, TRUE Texture ® technology provides texturing on the implant shell that is
designed  to  reduce  the  incidence  of  malposition,  rotation  and  capsular  contracture.  We  do  not  have  any  patents  or  patent
applications, but rely on trade secrets, proprietary know ‑how and regulatory barriers to protect our products and technologies.

breast implants in 1,788 women across 36 investigational sites in the United States. The clinical data we collected over an eight-
year  follow-up  period  demonstrated  rupture  rates,  capsular  contracture  rates  and  reoperation  rates  that  were  comparable  to  or
better than those of our competitors, based on our competitors’ published eight ‑year data.

Breast Implants.  We offer the following breast implants:

·

·

·

Anatomically  ‑shaped  textured.    A  full  line  of  textured,  anatomically  ‑shaped  HSC+  breast  implants,  all  of  which
incorporate  our  high  ‑strength,  cohesive  silicone  gel  and  TRUE  Texture  ®  technology.  Our  anatomically  ‑shaped
implants are engineered for shape retention and feature a gradual upper ‑pole slope and distributed volume that mimics
the characteristics of a natural breast. They also provide a desired balance between strength, shape retention and softness
and  are  designed  to  enhance  tissue  adherence  to  reduce  malposition  and  capsular  contracture.  Due  to  the  unique
relationship between our implant gel and our implant shells, our anatomically ‑shaped implants have enhanced ability to
retain  their  shape  without  sacrificing  the  desired  softness.  We  offer  these  anatomically  ‑shaped  implants  in  three
configurations: round ‑base, classic ‑base and oval ‑base. Our round ‑base implants are available in eight volumes, our
classic  ‑base  implants  are  available  in  eight  volumes  and  our  oval  ‑base  implants  are  available  in  three  projection
profiles and 25 volumes.

Round textured.  A full line of textured, round HSC breast implants, all of which incorporate our high ‑strength, cohesive
silicone  gel  and  TRUE  Texture  ®  technology.  Our  textured,  round  implants  maintain  softness  and  are  designed  to
enhance tissue adherence that reduces malposition and capsular contracture. We offer these textured, round implants in
three projection profiles: low, moderate and high. Our low projection implants are available in 15 volumes, our moderate
plus projection implants are available in 16 volumes and our high projection implants are available in 14 volumes.

Round smooth.  A full line of smooth, round HSC and HSC+ breast implants, all of which incorporate our high ‑strength,
cohesive  silicone  gel.  Our  smooth,  round  implants  are  designed  to  deliver  full  upper  ‑pole  aesthetic  results  without
compromising softness. We offer these smooth, round implants in five projection profiles: low, moderate, moderate plus,
moderate  high  and  high  .  Additionally,  in  the  third  quarter  of  2015  ,  we  introduced  two  implant  projection  profiles
available in HSC+ gel in 30 new volumes mirroring the existing HSC moderate plus and high projection profiles.

Breast Tissue Expanders.  We offer a full line of breast tissue expanders, most of which are marketed as ACX, in 25

different shapes and sizes that include single and double chamber tissue expanders. Our double chamber tissue

6

 
Table of Contents

expanders  are  unique  to  the  marketplace  and  feature  technology  that  was  designed  to  allow  controlled  and  differentiated
expansion  of  breast  tissue.  Our  breast  tissue  expanders  are  used  in  breast  reconstruction  and  implanted  during  or  after  the
completion  of  a  mastectomy  and  before  the  patient  has  enough  tissue  to  adequately  cover  a  breast  implant.  Our  breast  tissue
expanders  are  temporary  devices  intended  to  aid  in  the  process  of  recreating  tissue  coverage  to  allow  for  the  placement  of  the
final implant to reconstruct the breast.

Other
Products

We also offer a range of other aesthetic products that have received 510(k) clearance from the FDA, including:

body contouring and other implants, including gluteal, pectoral, calf, facial and nasal implants, and nasal stents, all made
from single pieces of silicone elastomer;

silicone  elastomer  oval  carving  blocks  that  can  be  shaped  and  sized  by  surgeons  to  address  congenital  and  other
deformities caused by trauma or tumor removal ;

scar management products under the brand Medgel that use a compound of biocompatible, medical ‑grade silicone gel or
sheeting specifically formulated to treat or prevent various types of scars;

temporary,  single  ‑use,  saline  ‑filled  breast  implant sizers  that  can  be  used  to  help  identify  the  correct  style  and  size
implant for an individual patient; and

non ‑breast tissue expanders, which are temporary devices intended to aid in the process of expanding tissue and skin
surface area for burn care and other reconstructive use.

Our Technology

Our current portfolio of breast implants utilizes what we believe are the most advanced technologies currently available
on  the  market.  These  technologies  are  supported  by  rigorous  product  testing,  analytics  and  clinical  data.  The  advanced
technologies in our products include:

High
‑‑strength,
cohesive
silicone
gel.
 Our HSC and HSC+ breast implants offer a desired balance between strength,
shape retention and softness due to the high ‑strength, cohesive silicone gel used in our manufacturing process. The use of high
‑strength, cohesive silicone gel in our HSC and HSC+ breast implants allows the breast implants to hold a controlled shape while
maintaining a soft feel.

The  silicone  material used  in  our  breast  implants  has  been  designed  to  provide  the  characteristics  desired  by  Plastic
Surgeons for breast implants. At present, we are the only company in the United States that has received FDA approval to use this
specific silicone material in our products.

We  have  completed  a  number  of  studies  conducted  by  independent  laboratories  to  demonstrate  the  competitive
advantages  of  using  high  ‑strength,  cohesive  silicone  gel  in  our  breast  implants.  We  believe  this  technology  differentiates  our
breast implants for the following reasons:

·

·

·

our implant gel is stronger, which is evidenced by its resistance to gel fracture;

due to the unique relationship between our implant gel and our implant shells, our implants have an enhanced ability to
retain their shape while preserving the shape of anatomically ‑shaped implants without sacrificing the desired softness;
and

our shaped implants are softer and more elastic than our competitors’ shaped implants.

7

 
Table of Contents

We  believe  the  beneficial  properties  of  our  implants  arise  from  the  characteristics  of  the  gel,  as  well  as  the  unique
integration of the gel with our implant shell. Inside each of our implants, the gel adheres to the shell, creating additional structural
strength and shape retention in the implant. This results in the ability to deliver strength and shaping capability without a stiffer
gel or implant and without sacrificing the desired softness. We typically evaluate these characteristics using the following metrics:

·

Peel ‑force.  Peel ‑force is measured by the amount of force, measured in pound ‑force, or lbf, necessary to separate the
outer shell of the implant from the intern al gel filling. A greater peel ‑ force measurement indicates greater gel ‑shell
integration. In the case of anatomically ‑shaped implants, greater peel ‑force can also be an indication of the ability of
the implant to retain its shape, particularly the upper portions of the implant, also referred to as the upper pole. Upper
pole stability is of particular importance in preserving the desired anatomical shape of an implant over time.

· Gel strength.  Gel strength is measured by the amount of force, measured in lbf, required to cause permanent fractures in

the gel. A larger value indicates greater strength.

· Gel  elasticity  and  implant  elasticity.    Gel  elasticity  and  implant  elasticity  can  be  measured  by  the  level  of  resistance,
measured  in  millimeters,  or  mm,  to  an  applied  constant  force.  A  higher  value  represents  greater  softness  and  a  lower
deformation value represents greater firmness.

TRUE
Texture
®
.
 We sell breast implants that are available with a smooth outer surface or with an outer surface that is
textured using TRUE Texture ® technology. We believe our textured breast implants using TRUE Texture ® technology offer us
clinical advantages over our competitors’ textured products, including:

·

·

better tissue adherence to reduce the incidence of malposition and rotation; and

reduction  in  the  rate  of capsular  contracture,  a complication  in which  the patient’s  body creates  a  scar  ‑tissue capsule
around the implant that can tighten and squeeze the implant potentially causing discomfort, pain and even dislocation of
the implant. While we have neither sought nor obtained FDA approval to state that TRUE Texture ® technology reduces
the incidence of capsular contracture, we believe it may significantly reduce this risk, as evidenced by the lower rates of
capsular contraction reported over a five ‑year follow ‑up period in our ongoing clinical trial.

On a breast implant, the desired texture should have a proportionate amount of surface disruption, as overly aggressive
texture  can  result  in  double  ‑capsule  formation  while  not  enough  texturing  can  result  in  a  lack  of  adherence  resulting  in
malposition  or  rotation.  We  believe  that  TRUE  Texture  ® technology  has  the  right  combination  of  surface  disruption  without
overly aggressive texturing.

We use the competitive advantages demonstrated by the independent laboratory results above and our clinical results for
our  breast  implants  incorporating  high  ‑strength,  cohesive  silicone  gel  and  TRUE  Texture  ®  technology  to  market  and
differentiate our products to Plastic Surgeons.

Our Clinical Data

In  2012,  our  breast  implants  were  approved  by  the  FDA,  based  on  data  we  co  llected  from  our  ongoing,  long  ‑ term
clinical  trial  of  our  breast  implants  in  1,788  women  across  36  investigational  sites  in  the  United  States,  which  included  3,506
implants (approximately 53% of which were smooth and 47% of which were textured). Our clinical trial results demonstrate the
safety  and  effectiveness  of  our  breast  implants  and  provide  Plastic  Surgeons  and  their  patients  the  security  and  confidence  to
choose our products.

Our clinical  trial  is the largest  prospective,  long ‑term safety and effectiveness  pivotal study of breast implants in the
United States and included the largest magnetic resonance imaging, or MRI, cohort with 571 patients. The MRI cohort is a subset
of study patients that underwent regular MRI screenings in addition to the other aspects of the clinical trial protocol prior to FDA
approval. Post-approval, all patients in the Study are subject to serial MRI screening as part of the clinical protocol . The clinical
data  we collected  over  an  eight  ‑year follow ‑up  period  demonstrated  rupture  rates,  capsular  contracture  rates  and  reoperation
rates that were comparable to or better than those of our competitors, at similar time points. In addition to our pivotal study, our
clinical data is supported by our Continued Access Study of 2,497 women in

8

 
Table of Contents

the United States. We have also commissioned a number of bench trials run by independent laboratories that we believe further
demonstrate the advantages of our breast implants over those of our competitors.

We, and our two competitors were required to run independent ten ‑year clinical studies to obtain PMA approval from
the  FDA.  Our  clinical  study  was  not  designed  to  facilitate  head  ‑to  ‑head  comparisons.    However,  our  clinical  data  and  our
competitors’ clinical data are publicly available to both surgeons and patients who are able to use such data to compare and contra
s t competing implants.

Our Services

Our services are designed to cater to the specific needs of Plastic Surgeons to enable them to maintain and grow their

Educational
and
Marketing
Initiatives.
  We have implemented  educational  and marketing  initiatives  with a focus on

both Plastic Surgeons and their patients considering breast augmentation or reconstruction.

Plastic  Surgeons.    In  order  to  educate  Plastic  Surgeons  about  our  product  lines  and,  in  particular,  about  the
proper use of our anatomically ‑shaped breast implants, we provide a variety of education programs for Plastic Surgeons
under the banner of the Sientra Education Forum.

· we have developed a tablet ‑based mobile marketing tool for our sales representatives to use while calling on accounts
that includes access to our patient  and surgeon labeling,  published clinical  studies, marketing  literature,  details  on our
warranty and C3 programs, our educational iBooks and more.

· we  host  symposia  with  one  or  more  key  ‑note  speakers  who  speak  on  topics  ranging  from  our  corporate  identity  and

customer service offerings to surgical tips and suggestions from thought ‑leading Plastic Surgeons.

· we produce comprehensive guides for Plastic Surgeons via the Internet, referred to as iBooks, to provide them training

and expertise on the implantation of anatomically ‑shaped breast implants.

9

 
Table of Contents

· we send a limited number of Plastic Surgeons to Europe to observe surgeries and train with world ‑renowned surgeons
who have been implanting anatomically ‑shaped breast implants for decades and, upon return to the United States, we
engage them as consultant ‑educators to conduct tr aining sessions for other U.S. ‑ based Plastic Surgeons.

· we periodically sponsor educational surgical preceptorships where a small group of Plastic Surgeons are able to observe

a live surgery conducted by one of our trained preceptors and train with that preceptor.

Patients.    We  have  been  engaging  directly  with  consumers  who  are  considering  breast  augmentation  or
reconstruction.  We  initially  focused  our  consumer  educational  and  marketing  activities  on  websites  where  consumers
come to research their breast augmentation or reconstruction options, including:

·

·

our  own  consumer  website,  branded  with  our  “Feel  So  Good”  campaign,  that  provides  resources  for  consumers
considering  breast  augmentation  or  reconstruction,  including  referrals  and  commentaries,  product  descriptions,  patient
planning guides and educational brochures and information regarding our rupture warranty and C3 programs; and

our  exclusive  collaboration  with  RealSelf,  the  leading  online  community  helping  people  make  confident  choices  in
elective  cosmetic  procedures.  Together  with  RealSelf,  we  deliver  fresh  and  meaningful  content  to  the  RealSelf
community that answers common questions patients have regarding breast augmentation. This content is featured on a
dedicated Sientra page on RealSelf’s website designed to build consumer engagement with the brand and open up the
online conversation around breast augmentation directly with Plastic Surgeons.

We  believe  that  our  innovative  services,  including  industry  ‑leading  product  programs  and  warranties,  enhanced
customer  service  offerings  and  educational  and  marketing  initiatives,  deliver  an  improved  customer  experience  to  Plastic
Surgeons and their patients.

Sales and Marketing

As  of  December  31,  2015  ,  we  had  a  sales  organization  of  51  employees,  including  sales  representatives  and  sales
management.  We  assign  sales  territories  based  on  the  regions  with  the  highest  concentration  of  accounts.  Our  sales  team  is
supported by customer and sales experience teams, which provide full ‑time telephonic and email customer support to our sales
representatives and customers.

In  addition,  our  marketing  team  leads  our  efforts  in  brand  development,  trade    show  attendance,  educational  forums,

product messaging, website development and advertising, among others.

Research and Development

We  have  incurred,  and  expect  to  continue  to  incur,  significant  research  and  development  expenses.  Our  research  and
development expenses were approximately $7.2  million, $4.7  million and $4.5  million for the years ended December 31, 2015 ,
  2014 and 2013 , respectively. Our research and development expenses primarily consist of costs associated with our clinical and
post ‑approval studies, regulatory activity and product development, including our efforts to seek approval for a range of breast
implant  line  extensions  that  would  allow  us  to  sell  Breast  Products  in  additional  styles,  sizes  and  projections  that  we  do  not
currently offer.

Manufacturing and Quality Assurance

All of our products are listed under our FDA Medical Device Establishment Registration and Device Listing where it
indicates we are the specification developer of our products, and except for our breast implant sizers ,   we are the owner of our
products’ FDA approvals and clearances. This means that we are primarily responsible for the design,  manufacturing and quality
assurance  of  our  products.  However,  we  do  not  manufacture  our  products  ourselves.  Instead,  we  rely  on  Silimed  ,  our      sole
source, third-party manufacturer located in Brazil ,   to manufacture and package our silicone gel breast implants, tissue expanders
and  other  products  to  our  specifications.  Silimed  has  over  35  years  of  experience  manufacturing  silicone  ‑based  implants  and
distributes its products to over 60 countries worldwide. When we receive our products from Silimed, we inspect a representative
sample  of  packaging  and  labeling  prior  to  shipping  them  to  our  customers.  We  maintain  strategic  levels  of  inventory  at  our
storage facilities located in Santa Barbara, California.

Table of Contents

We and Silimed are subject to the FDA’s Quality System Regulation, or QSR, reporting requirements and current Good
Manufacturing Practices, or cGMP , audits by the FDA. Under the QSR and cGMP requirements, manufacturers, including third
party  manufacturers,  must  follow  stringent  design,  testing,  production,  control,  supplier  and  contractor  selection,  complaint
handling,  documentation  and other quality  assurance  procedures  during all  aspects of the manufacturing  process. Both Silimed
and us have been inspected by the FDA regularly, and no FDA Form 483 observations, which are issued when an FDA inspector
has observed any conditions that in his or her judgment may constitute violations of the Food Drug and Cosmetic Act and related
Acts, or FD&C, may be in violation of FDA’s requirements. Silimed has had four FDA inspections in 14 years and is also audited
periodically by our quality department to ensure conformity with the specifications, policies and procedures for our products.

At present, except for our breast implant sizers, all of our products, including our silicone gel breast implants and breast
tissue expanders, are manufactured by Silimed pursuant to an amended and restated exclusivity agreement with Silimed , which
we refer to as the Silimed Agreement. Pursuant to the Silimed Agreement, Silimed manufactures and supplies products ordered
by  us  for  distribution  in  the  United  States  and  Canada,  which  we  refer  to  as  the  Territory.  We  agreed  to  use  commercially
reasonable efforts to promote, sell and distribute the products in the Territory. In addition to Silimed’s existing products, we have
the exclusive right to sell and distribute any new products manufactured by Silimed during the term of the Silimed Agreement.
Silimed sells the products to us at a fixed cost, which may be increased by no more than a low single ‑digit percentage per annum.

The Silimed Agreement provides that Silimed will not provide its products to any third party in the Territory, with the
exception of the distribution of its gastric and urology products pursuant to pre ‑existing supply agreements that it has with third
‑party distributors,  and we have agreed  not to sell Silimed’s  products to any third party if we have reason to believe  that such
products have been or will be distributed outside of the Territory. We have also agreed not to distribute any product that directly
competes with a product manufactured by Silimed in the Territory.

In  the  event  Silimed  fails  to  supply  products  ordered  by  us,  we  may,  under  certain  circumstances,  exercise
manufacturing  rights  to  manufacture  the  products  directly  or  through  a  third  party  manufacturer.  Pursuant  to  the  Silimed
Agreement,  Silimed  granted  to  us  an  exclusive,  royalty  ‑free,  non  ‑transferable  license  to  use  certain  of  its  trademarks  in  the
Territory, including in the event Silimed fails to supply the products to us and in connection with the marketing and sale of the
products in the Territory. In addition, the Silimed Agreement allocates intellectual property rights between the parties, including
that the parties will jointly own all developments, modifications, enhancements or alterations of products jointly created by the
parties, subject to certain restrictions concerning the use of such improvements outside of the Territory. Each party is subject to
certain limitations and other restrictions on the transfer of the other party’s technology to third parties.

The Silimed Agreement can be terminated by either party under certain limited circumstances, including in connection
with  the  other  party’s  breach  of  any  of  its  material  obligations  which  such  breaching  party  fails  to  cure  within  60  days  of
receiving  notice  from  the  non  ‑breaching  party.  If  the  breach  relates  only  to  single  product,  then  the  non  ‑breaching  party  is
entitled to terminate the agreement with respect to that specific product. The parties may also terminate the agreement at any time
on a product ‑by ‑product basis upon mutual written agreement of the parties.

The term of the Silimed Agreement will continue until April 2017.

Several recent events have occurred which have affected our ability to rely on Silimed as our source for our silicone gel
breast  implants,  tissue  expanders  and  other  products  in  the  short  and  long  term,  including  the  suspension  of  Silimed’s  CE
certificate by TUV SUD, Silimed’s notified body under EU regulation, relating to particles on Silimed breast products , followed
by Brazilian regulatory inquiries and a temporary suspension by the Brazilian regulatory agency ANVISA and the Department of
the Secretary  of State of Rio de Janeiro  of the manufacturing  and shipment of all medical  devices made by Silimed,  including
products manufactured for Sientra. As a result of this suspension, between October 9, 2015 and March 1, 2016, we voluntarily
placed  a  temporary  hold  on  the  sale  of  all  Sientra  devices  manufactured  by  Silimed  and  recommended  that  plastic  surgeons
discontinue implanting the devices until further notice . As of March 1, 2016, after ongoing discussions with the FDA and our
own review of the matter with the assistance of independent experts in quality management systems, GMP and data-based risk
assessment, we lifted this temporary hold on sale and also sent a letter to our Plastic Surgeons informing them of our market re-
entry plans.

In addition, on October 22, 2015, there was a fire in the manufacturing building where Silimed primarily manufactures
Sientra’s  breast  implants.  We  are  working  with  Silimed  to  seek  clarity  as  to  the  near  and  long-term  capabilities  of  Silimed’s
manufacturing operations, including the status of equipment that is used to manufacture breast

11

 
Table of Contents

implants  and  the  potential  feasibility,  production  capacity  and  timing  related  to  Silimed’s  ability  to  manufacture  our  breast
implants.

Competition

The medical device industry is intensely competitive, subject to rapid change and highly sensitive to the introduction of
new products or other market activities of industry participants. We primarily compete with two companies that manufacture and
sell breast implants in the United States: Johnson & Johnson through its wholly owned subsidiary, Mentor Worldwide, LLC, or
Mentor, and Allergan plc, or Allergan.

Both  of  our  U.S.  competitors  are  either  publicly  ‑traded  companies  or  divisions  or  subsidiaries  of  publicly  ‑traded
companies with significantly more market share and resources than we have. These companies have greater financial resources
for sales, marketing and product development, broader established relationships with healthcare providers and third ‑party payors,
and larger and more established distribution networks. In some instances, our competitors also offer products that include features
that  we  do  not  currently  offer.  For  example,  Allergan  sells  temporary  gel  sizers  for  silicone  gel  implants  and  we  sell  only
temporary  saline  filled  sizers.  In  addition,  our  competitors  may  offer  pricing  programs  with  discounts  across  their  non  ‑breast
aesthetic product portfolios.

We also face potential future competition from a number of companies, medical researchers and existing medical device
companies  that  may  be  pursuing  new  implant  technologies,  new  material  technologies  and  new  methods  of  enhancing  and
reconstructing the breast.

We believe the primary competitive factors in our markets include:

·

·

·

·

·

·

breadth of portfolio;

technological characteristics of products;

clinical evidence;

product price;

customer service; and

support by key opinion leaders.

Government Regulation

Our  products  are  medical  devices  subject  to  extensive  regulation  by  the  FDA  and  other  federal  and  state  regulatory
authorities,  Health  Canada  and,  if  we  commence  international  sales  outside  of  the  United  States  and  Canada,  other  regulatory
bodies in other countries.

Unless an exemption applies, each new or significantly modified medical device we seek to commercially distribute in
the  United  States  will  require  either  a  pre  ‑market  notification  to  the  FDA  requesting  permission  for  commercial  distribution
under Section 510(k) of the FDCA, also referred to as a 510(k) clearance, or approval from the FDA of a pre ‑market approval, or
PMA,  application.  Both  the  510(k)  clearance  and  PMA  approval  processes  can  be  expensive,  lengthy  and  require  payment  of
significant user fees, unless an exemption is available.

The FDA classifies medical devices into one of three classes. Unless specifically exempted from certain requirements,
all three classes of devices are subject to general controls such as labeling, pre ‑market notification and adherence to the FDA’s
Quality System Regulation, or QSR, which cover manufacturers’ methods and documentation of the design, testing, production,
control,  quality  assurance,  labeling,  packaging,  sterilization,  storage  and  shipping  of  products.  Devices  deemed  to  pose  low  to
moderate  risk  are  placed  in  Class  I  or  II,  which,  absent  an  exemption,  requires  the  manufacturer  to  obtain  a  510(k)  clearance.
Class  II  devices  are  subject  to  special  controls  such  as  performance  standards,  post  ‑market  surveillance,  FDA  guidelines,  or
particularized  labeling  requirements,  as  well  as  general  controls.  Some  low  risk  devices  are  exempted  by  regulation  from  the
510(k)  clearance  requirement,  and/or  the  requirement  of  compliance  with  substantially  all  of  the  QSR.  A  PMA  application  is
required for devices deemed by the FDA to pose the greatest risk, such as life ‑sustaining, life ‑ supporting or certain implantable
devices,  including  all  breast  implants,  or  devices  that  are  “not  substantially  equivalent”  either  to  a  device  previously  cleared
through  the  510(k)  process  or  to  a  “preamendment”  Class  III  device  in  commercial  distribution  in  the  United  states  before
May 28, 1976 for which a regulation requiring a PMA application has not been issued by the FDA.

Our tissue expanders and our body contouring, facial and nasal implants received FDA clearance as Class II devices at
various dates prior to approval of our breast implants in March 2012. To obtain 510(k) clearance, we must submit a pre ‑market
notification  demonstrating  that  the  proposed  device  is  substantially  equivalent  to  a  previously  cleared  510(k)  device  or  a
preamendment device. The FDA’s 510(k) clearance pathway usually takes from three to 12 months from the date the application
is completed, but it can take significantly longer and clearance is never assured. Although many 510(k) pre ‑market notifications
are cleared without clinical data, in some cases, the FDA requires significant clinical data to support substantial equivalence. In
reviewing  a  pre  ‑market  notification,  the  FDA  may  request  additional  information,  including  clinical  data,  which  may
significantly prolong the review process. After a device receives 510(k) clearance, any modification that could significantly affect
its safety or effectiveness, or that would constitute a new or major change in its intended use, will require a new 510(k) clearance
or,  depending  on  the  modification,  could  require  a  PMA  application.  The  FDA  requires  each  manufacturer  to  make  this
determination initially, but the FDA can review any such decision and can disagree with a manufacturer’s determination. If the
FDA  disagrees  with  a  manufacturer’s  determination  regarding  whether  a  new  pre  ‑market  submission  is  required  for  the
modification of an existing device, the FDA can require the manufacturer to cease marketing and/or recall the modified device
until 510(k) clearance or approval of a PMA application is obtained. If the FDA requires us to seek 510(k) clearance or approval
of a PMA application for any modifications to a previously cleared product, we may be required to cease marketing or recall the
modified device until we obtain this clearance or approval. In addition, in these circumstances, we may be subject to significant
regulatory fines or penalties for failure to submit the requisite PMA application(s). In addition, the FDA is currently evaluating
the 510(k) process and may make substantial changes to industry requirements.

Silicone gel ‑filled breast implants are treated as Class III devices and a full PMA is required. A PMA for our breast
implants was approved by the FDA in March 2012. The PMA application process is generally more costly and time consuming
than the 510(k) process and requires proof of the safety and effectiveness of the device to the FDA’s satisfaction. Accordingly, a
PMA application must be supported by valid scientific evidence that typically includes, but is

13

 
Table of Contents

not limited to, extensive technical information regarding device design and development, pre ‑clinical and clinical trial data, and
manufacturing and labeling information to demonstrate to the FDA’s satisfaction the safety and effectiveness of the device for its
intended use. After a PMA application is submitted and found to be sufficiently complete, the FDA begins an in ‑depth review of
the submitted information. By statute, the FDA has 180 days to review the “accepted application,” although, generally, review of
the application  takes between  one and three years, but may take  significantly  longer. During this review  period, the FDA may
request additional information or clarification of information already provided. Also during the review period, an advisory panel
of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the
FDA  as  to  the  approvability  of  the  device.  In  addition,  the  FDA  generally  will  conduct  a  pre  ‑approval  inspection  of  the
manufacturing facility to evaluate compliance with QSR, which requires manufacturers to implement and follow elaborate design,
testing, control, documentation and other quality assurance procedures in the device design and manufacturing process.

The FDA may approve a PMA application with post ‑approval conditions intended to ensure the safety and effectiveness
of the device including, among other things, restrictions on labeling, promotion, sale and distribution and collection of long ‑term
follow ‑up data from patients in the clinical study that supported approval. Failure to comply with the conditions of approval can
result in materially adverse enforcement action, including the loss or withdrawal of the approval. New PMA applications or PMA
application supplements are required for significant modifications to the manufacturing process, labeling and design of a device
that could affect the safety or effectiveness of the device, including, for example, certain types of modifications to the device’s
indication for use, manufacturing process, labeling and design. PMA supplements often require submission of the same type of
information as a PMA application, except that the supplement is limited to information needed to support any changes from the
device covered by the original PMA application, and may not require as extensive clinical data or the convening of an advisory
panel, depending on the nature of the proposed change.

Clinical 
Trials.
  A  clinical  trial  is  almost  always  required  to  support  a  PMA  application  and  may  be  required  for  a
510(k) pre ‑market notification. In the United States, absent certain limited exceptions, human clinical trials intended to support
product clearance or approval require an Investigational Device Exemption, or IDE, application. Some types of studies deemed to
present  “non  ‑significant  risk”  are  deemed  to  have  an  approved  IDE  once  certain  requirements  are  addressed  and  institutional
review board, or IRB, approval is obtained. If the device presents a “significant risk” to human health, as defined by the FDA, the
Sponsor must submit an IDE application to the FDA and obtain IDE approval prior to commencing the human clinical trials. The
IDE application must be supported by appropriate data, such as animal and laboratory testing results, showing that it is safe to
evaluate  the  device  in  humans  and  that  the  testing  protocol  is  scientifically  sound.  The  IDE  application  must  be  approved  in
advance by the FDA for a specified number of subjects, unless the product is deemed a non ‑significant risk device and eligible
for  more  abbreviated  IDE  requirements.  Clinical  trials  for  a  significant  risk  device  may  begin  once  the  IDE  application  is
approved  by  the  FDA  and  the  responsible  institutional  review  boards  at  the  clinical  trial  sites.  There  can  be  no  assurance  that
submission of an IDE will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place it
on hold or terminate it if, among other reasons, it concludes that the clinical subjects are exposed to unacceptable health risks that
outweigh the benefits of participation in the study. During a study, we are required to comply with the FDA’s IDE requirements
for investigator selection, clinical trial monitoring, reporting, record keeping and prohibitions on the promotion of investigational
devices  or  making  safety  or  efficacy  claims  for  them.  We  are  also  responsible  for  the  appropriate  labeling  and  distribution  of
investigational  devices.  Our  clinical  trials  must  be  conducted  in  accordance  with  FDA  regulations  and  federal  and  state
regulations concerning human subject protection, including informed consent and healthcare privacy. The investigators must also
obtain  patient  informed  consent,  rigorously  follow  the  investigational  plan  and  study  protocol,  control  the  disposition  of
investigational devices and comply with all reporting and recordkeeping requirements. The FDA’s grant of permission to proceed
with clinical testing does not constitute a binding commitment that the FDA will consider the study design adequate to support
clearance  or  approval.  In  addition,  there  can  be  no  assurance  that  the  data  generated  during  a  clinical  study  will  meet  chosen
safety and effectiveness endpoints or otherwise produce results that will lead the FDA to grant marketing clearance or approval.

Other
Regulatory
Requirements.
 Even though our breast implants have been approved and commercialized, numerous
regulatory requirements apply after a device is placed on the market, regardless of its classification or pre ‑market pathway. These
include, but are not limited to:

·

establishment registration and device listing with the FDA;

14

 
Table of Contents

· QSR, which requires manufacturers, including third-party manufacturers, to follow stringent design, testing, production,
control,  supplier  and  contractor  selection,  complaint  handling,  documentation  and  other  quality  assurance  procedures
during all aspects of the manufacturing process;

·

labeling  regulations  that  prohibit  the  promotion  of  products  for  uncleared  or  unapproved,  or  “off  ‑label,”  uses,  and
impose other restrictions on labeling, advertising and promotion;

· medical Device Reporting, or MDR, regulations, which require that 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

·

corrections and removals reporting regulations, which require that manufacturers report to the FDA field corrections and
product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the
FDCA  that  may  present  a  risk  to  health.  In  addition,  the  FDA  may  order  a  mandatory  recall  if  there  is  a  reasonable
probability that the device would cause serious adverse health consequences or death.

Also, the FDA requires us to conduct post ‑market surveillance studies and to maintain a system for tracking our breast
implants  through  the  chain  of  distribution  to  the  patient  level.  The  FDA  and  the  Food  and  Drug  Branch  of  the  California
Department  of  Health  Services  enforce  regulatory  requirements  by  conducting  periodic,  unannounced  inspections  and  market
surveillance. Inspections may include the manufacturing facilities of our subcontractors.

Failure by us or our manufacturer to comply with applicable regulatory requirements can result in enforcement actions
by  the  FDA  and  other  regulatory  agencies.  These  may  include,  but  may  not  be  limited  to,  any  of  the  following  sanctions  or
consequences:

· warning letters or untitled letters that require corrective action;

·

·

·

·

·

·

·

·

·

fines and civil penalties;

unanticipated expenditures;

delays in or refusal to grant requests for 510(k) clearance or pre ‑market approval of new products or modified products;

FDA refusal to issue certificates to foreign governments needed to export products for sale in other countries;

suspension or withdrawal of FDA clearance or approval;

product recall, detention or seizure;

operating restrictions, partial suspension or total shutdown of production;

injunctions and consent decrees; and

criminal prosecution.

We  and  our  contract  manufacturers  and  some  suppliers  of  components  or  device  accessories  also  are  required  to
manufacture our products in compliance with cGMP requirements set forth in the QSR. The QSR requires a quality system for the
design,  manufacture,  packaging,  labeling,  storage,  installation  and  servicing  of  marketed  devices,  and  it  includes  extensive
requirements with respect to quality management and organization, device design, buildings, equipment, purchase and handling
of  components  or  services,  production  and  process  controls,  packaging  and  labeling  controls,  device  evaluation,  distribution,
installation, complaint handling, servicing, and record keeping. The FDA evaluates compliance with the QSR through periodic,
unannounced inspections that may include the manufacturing facilities of our subcontractors. If the FDA believes that we or any
of  our  contract  manufacturers  or  regulated  suppliers  are  not  in  compliance  with  these  requirements,  it  can  shut  down  our
manufacturing operations, require recall of our products, refuse

15

 
Table of Contents

to approve new marketing applications, institute legal proceedings to detain or seize products, enjoin future violations or assess
civil and criminal penalties against us or our officers or other employees.

Healthcare 
Regulatory 
Laws.
  Our  business  activities,  including  but  not  limited  to,  research,  sales,  marketing,
promotion,  distribution,  medical  education  and  other  activities  are  subject  to  regulation  under  additional  healthcare  laws  by
numerous  regulatory  and  enforcement  authorities  in  the  United  States,  in  addition  to  the  FDA.  These  laws  include,  without
limitation,  state  and  federal  anti  ‑kickback ,  false  claims,  physician  sunshine  , and patient  data  privacy  and  security  laws  and
regulations, including but not limited to those described below.

Additionally, our relationships with healthcare providers and other third parties are subject to scrutiny under these laws.
Non  ‑compliance  with  the  laws  described  below  may  generally  result  in  the  imposition  of  civil,  criminal  and  administrative
penalties,  damages, monetary  fines, disgorgement,  individual  imprisonment,  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  adversely  affect  our  ability  to  operate  our  business  and  our  results  of
operations.  Defending  against  any  actions  for non  ‑compliance of such  laws  can  be  costly,  time  ‑ consuming  and  may  require
significant financial and personnel resources. Therefore, even if we are successful in defending against any such actions that may
be brought against us, our business may be impaired.

Federal
Anti
‑‑Kickback
Law.
 The federal Anti ‑Kickback Statute prohibits, among other things, knowingly or willfully
soliciting, receiving, offering, or paying remuneration, directly or indirectly, to induce, or in return for, either the referral of an
individual or the purchase, or recommendation, order or furnishing of an item or service reimbursable under a federal healthcare
program, such as the Medicare and Medicaid programs. The definition of “remuneration” has been broadly interpreted to include
anything  of  value,  including  such items  as  improper  payments,  gifts,  discounts,  the furnishing  of  supplies  or  equipment,  credit
arrangements,  waiver  of  payments  and  providing  anything  at  less  than  its  fair  market  value.  There  are  a  number  of  statutory
exceptions  and  regulatory  safe  harbors  protecting  certain  common  activities  from  prosecution.  Failure  to  meet  all  of  the
requirements  of  a  particular  applicable  statutory  exception  or  regulatory  safe  harbor  does  not  make  the  conduct  per  se  illegal
under  the  federal  Anti  ‑Kickback  Statute.  Instead,  the  legality  of  the  arrangement  will  be  evaluated  on  a  case  ‑by ‑case basis
based on a cumulative review of all of its facts and circumstances.

The penalties for violating the federal Anti ‑Kickback Statute include imprisonment for up to five years, fines of up to
$25,000 per violation and possible exclusion from federal healthcare programs such as Medicare and Medicaid. Further, a person
or entity does not need to have actual knowledge of this statute or specific intent to violate it in order to commit a violation . In
addition, 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 federal civil False Claims Act, or FCA.

We  have  entered  into  consulting,  speaker  and  other  financial  arrangements  with  physicians,  including  some  who
prescribe  or  recommend  our  products  to  patients.  We  engage  such  physicians  as  consultants,  advisors  and  to  educate  other
physicians. Noncompliance with the federal Anti ‑Kickback Statute could result in the penalties set forth above.

Federal
Civil
False
Claims
Act.
 The FCA, prohibits any person from knowingly presenting, or causing to be presented,
a false claim for payment to the federal government, or knowingly making, using or causing to be made or used, a false record or
statement  material  to  a  false  or  fraudulent  claim  to  the  federal  government.  The  FCA  has  been  used  to  prosecute  persons
submitting claims for payment that are inaccurate or fraudulent, that are for services not provided as claimed, or for services that
are not medically  necessary.  Manufacturers  can be held liable  under the FCA if they are deemed to “cause”  the submission of
false  or  fraudulent  claims  by,  for  example,  providing  inaccurate  billing  or  coding  information  to  customers  or  promoting  a
product  off  ‑label.  Penalties  for  FCA  violations  include  three  times  the  actual  damages  sustained  by  the  government,  plus
mandatory  civil  penalties  of  between  $5,500  and  $11,000  for  each  separate  false  claim,  the  potential  for  exclusion  from
participation in federal healthcare programs, and, although the federal FCA is a civil statute, FCA violations may also implicate
various federal criminal statutes.

In  addition  to  actions  initiated  by  the  government  itself,  the  statute  authorizes  actions  to  be  brought  on  behalf  of  the
federal  government  by  a  private  party  having  knowledge  of  the  alleged  fraud,  known  as  “qui  tam”  whistleblower  lawsuits.
Because the complaint is initially filed under seal, the action may be pending for some time before the defendant is even aware of
the action. If the government intervenes and is ultimately successful in obtaining redress in the matter, or if the plaintiff succeeds
in obtaining redress without the government’s involvement, then the plaintiff will receive a percentage of the recovery. Qui tam
actions have increased significantly in recent years, causing greater numbers of

16

 
Table of Contents

healthcare companies to have to defend a false claim action, pay fines or be excluded from Medicare, Medicaid or other federal or
state healthcare programs as a result of an investigation arising out of such action.

Federal
Criminal
False
Claims
Law
s
.
 The federal criminal false claims laws prohibit, among other things, knowingly
and willfully making, or causing to be made, a false statement or representation of a material fact for use in determining the right
to any benefit or payment under a federal health care program. A violation of these laws may constitute a felony or misdemeanor
and may result in fines or imprisonment.

Civil
Monetary
Penalties
Law.
 The f ederal Civil Monetary Penalties Law prohibits, among other things, the offering or
transferring of remuneration to a Medicare or Medicaid beneficiary that the person knows or should know is likely to influence
the beneficiary’s selection of a particular supplier of Medicare or Medicaid payable items or services. Noncompliance can result
in civil money penalties of up to $10,000 for each wrongful act, assessment of three times the amount claimed for each item or
service and exclusion from the federal healthcare programs.

Health
Insurance
Portability
and
Accountability
Act
of
1996.
 The Health Insurance Portability and Accountability Act
of  1996,  or  HIPAA,  augmented  two  federal  crimes:  healthcare  fraud  and  false  statements  relating  to  healthcare  matters.  The
healthcare fraud statute prohibits knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare
benefit  program,  including  private  payors.  A  violation  of  this  statute  is  a  felony  and  may  result  in  fines,  imprisonment  or
exclusion from governmental programs. The false statements statute prohibits knowingly and willfully falsifying, concealing or
covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or
payment for healthcare benefits, items or services. A violation of this statute is a felony and may result in fines or imprisonment.

HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  or  HITECH,  and
their implementing  regulations, including the F inal HIPAA O mnibus R ule published on January 25, 2013, mandates, among
other things, that certain types of entities and individuals adopts uniform standards for the electronic exchange of information in
common  healthcare  transactions,  as  well  as  standards  relating  to  the  privacy  and  security  of  individually  identifiable  health
information, which require the adoption of administrative, physical and technical safeguards to protect such information. Among
other  things,  HITECH  makes  certain  of  HIPAA’s  standards  and  requirements  directly  applicable  to  “business  associates”—
independent contractors or agents of covered entities that create, receive or obtain protected health information in connection with
providing  a  service  for  or  on  behalf  of  a  covered  entity.  HITECH  also  increased  the  civil  and  criminal  penalties  that  may  be
imposed against covered entities and business associates, and gave state attorneys general new authority to file civil actions for
damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with
pursuing  federal  civil  actions.  In  addition,  certain  state  laws  govern  the  privacy  and  security  of  health  information  in  certain
circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and
may  not  have  the  same  effect,  thus  complicating  compliance  efforts.  Failure  to  comply  with  these  laws,  where  applicable,  can
result in the imposition of significant civil and/or criminal penalties.

Physician
Payments
Sunshine
Act.
 The  Patient Protection and Affordable Care Act, as amended by the Health Care
and  Education  Reconciliation  Act  of  2010,  or  collectively,  PPACA,  imposed,  among  other  things,  new  annual  reporting
requirements for certain manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under
Medicare,  Medicaid,  or  the  Children’s  Health  Insurance  Program,  for  certain  payments  and  “transfers  of  value”  provided  to
physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family
members. Failure to submit timely, accurately, and completely the required information for all payments, transfers of value and
ownership or investment interests may result in civil monetary penalties of up to an aggregate of $150,000 per year and up to an
aggregate  of  $1  million  per  year  for  “knowing  failures  , ”      for  all  payments,  transfers  of  value  or  ownership  or  investment
interests  that  are  not  timely,  accurately,  and  completely  reported  in  an  annual  submission.  We  are  required  to  report  detailed
payment data and submit legal attestation to the accuracy of such data by March 31st of each calendar year .

In  addition,  there  has  been  a  recent  trend  of  increased  federal  and  state  regulation  of  payments  and  other  transfers  of
value  provided  to  healthcare  professionals  and  entities.  Similar  to  the  federal  law,  certain  states  also  have  adopted  marketing
and/or transparency laws relevant to device manufacturers, some of which are broader in scope. Certain states, such as California
and Connecticut, also mandate that device manufacturers implement compliance programs. Other states, such as Massachusetts
and  Vermont,  impose  restrictions  on  device  manufacturer  marketing  practices  and  require  tracking  and  reporting  of  gifts,
compensation, and other remuneration to healthcare professionals and entities. The need to build

17

 
Table of Contents

and maintain a robust compliance program with different compliance and/or reporting requirements increases the possibility that a
healthcare company may violate one or more of the requirements, resulting in fines and penalties

Additional
State
Healthcare
Laws.
 Many states have also adopted some form of each of the aforementioned laws, some
of which may be broader in scope and may apply regardless of payor. Nevertheless, a determination of liability under such laws
could result in fines and penalties and restrictions on our ability to operate in these jurisdictions.

Additionally, as some of these laws are still evolving, we lack definitive guidance as to the application of certain key
aspects of these laws as they relate to our arrangements with providers with respect to patient training. We cannot predict the final
form that these regulations will take or the effect that the final regulations will have on us. As a result, our provider and training
arrangements may ultimately be found to be not in compliance with applicable laws.

United 
States 
Foreign 
Corrupt 
Practices 
Act.
  The  United  States  Foreign  Corrupt  Practices  Act,  or  FCPA,  prohibits
United States corporations and their representatives from offering, promising, authorizing or making corrupt payments, gifts or
transfers  to  any  foreign  government  official,  government  staff  member,  political  party  or  political  candidate  in  an  attempt  to
obtain or retain business abroad. The scope of the FCPA would include interactions with certain healthcare professionals in many
countries.

International
Regulation.
 We may evaluate international expansion opportunities in the future. International sales of
medical  devices  are  subject  to  local  government  regulations,  which  may  vary  substantially  from  country  to  country.  The  time
required to obtain approval in another country may be longer or shorter than that required for FDA approval, and the requirements
may differ. There is a trend towards harmonization of quality system standards among the European Union, United States, Canada
and various other industrialized countries.

The primary  regulatory  body in Europe is that of the European  Union, which includes  most of the major  countries  in
Europe.  Other  countries,  such  as Switzerland,  have  voluntarily  adopted  laws and  regulations  that  mirror  those of  the European
Union with respect to medical devices. The European Union has adopted numerous directives and standards regulating the design,
manufacture, clinical trials, labeling and adverse event reporting for medical devices. Devices that comply with the requirements
of  a  relevant  directive  will  be  entitled  to  bear  the  CE  conformity  marking,  indicating  that  the  device  conforms  to  the  essential
requirements  of the applicable  directives  and, accordingly,  can be commercially  distributed  throughout Europe. The method  of
assessing conformity varies depending on the class of the product, but normally involves a combination of self ‑assessment by the
manufacturer  and  a  third  party  assessment  by  a  “Notified  Body.”  This  third  ‑party  assessment  may  consist  of  an  audit  of  the
manufacturer’s  quality  system  and  specific  testing  of  the  manufacturer’s  product.  An  assessment  by  a  Notified  Body  of  one
country within the European Union is required in order for a manufacturer to commercially distribute the product throughout the
European  Union.  Additional  local  requirements  may  apply  on  a  country  ‑by  ‑country  basis.  Outside  of  the  European  Union,
regulatory approval would need to be sought on a country ‑by ‑country basis in order for us to market our products.

Coverage
and
Reimbursement.
 Sales of our products depend, in part, on the extent to which the procedures using our
products will be covered by third ‑party payors, such as government health care programs, commercial insurance and managed
healthcare organizations. Breast augmentation procedures are generally performed on a cash ‑pay basis and are not covered by
third ‑party  payors.  In  contrast,  breast  reconstruction  procedures  may  be  covered  by  third  ‑party  payors,  but  such  third  ‑party
payors are increasingly limiting coverage and reducing reimbursements for medical products and services. In addition, the U.S.
government,  state  legislatures  and  foreign  governments  have  continued  implementing  cost  ‑containment  programs,  including
price controls, restrictions on coverage and reimbursement. Third-party payors are increasingly challenging the price, examining
the  medical  necessity  and  reviewing  the  cost-effectiveness  of  medical  drug  products  and  medical  services,  in  addition  to
questioning  their  safety  and  efficacy.      Adoption  of  price  controls  and  cost  ‑containment  measures,  and  adoption  of  more
restrictive policies in jurisdictions with existing controls and measures, could further limit our net sales and results.

Moreover, t he  process  for  determining  whether  a  third-party  payor  will  provide  coverage  for  a  product  or procedure
may be separate from the process for establishing the reimbursement rate that such a payor will pay for the product or procedure .
A payor’s decision to provide coverage for a product or procedure does not imply that an adequate reimbursement rate will be
approved. Further, one payor’s determination to provide coverage for a product or procedure does not assure that other payors
will also provide coverage for the product or procedure . Adequate third-party reimbursement may not be available to enable us to
maintain price levels sufficient to ensure profitability .

Health 
Reform.
 
 
 
 
 The  United  States  and  some  foreign  jurisdictions  are  considering  or  have  enacted  a  number  of
legislative and regulatory proposals to change the healthcare system in ways that could affect our business. Among policy makers
and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the
stated goals of containing healthcare costs, improving quality or expanding access.

By way of example, in the United States, the recent implementation of PPACA is an example that has the potential to
substantially  change  healthcare  financing  and  delivery  by  both  governmental  and  private  insurers,  and  significantly  impact  the
pharmaceutical  and medical  device  industries.  The PPACA imposed,  among other  things, a new federal  excise  tax of 2.3% on
certain entities that manufacture or import medical devices for sale in the United States and implemented payment system reforms
including  a  national  pilot  program  on payment  bundling to  encourage  hospitals,  physicians  and other  providers  to  improve  the
coordination, quality and efficiency of certain healthcare services through bundled payment models.   The medical device excise
tax has been suspended by the Consolidated Appropriations Act of 2016, or the CAA, with respect to medical device sales during
calendar years 2016 and 2017.  Absent further Congressional action, this excise tax will be reinstated for medical device sales
beginning  January  1,  2018.    The  CAA  also  temporarily  delays  implementation  of  other  taxes  intended  to  help  fund  PPACA
programs.  The  full  impact  of  the  PPACA  on  our  business  remains  unclear.    There  have  been  judicial  and  Congressional
challenges to certain aspects of the PPACA, and we expect there will be additional challenges and amendments in the future.

In  addition,  other  legislative  changes  have  been  proposed  and  adopted  since  the  PPACA  was  enacted.  On  August  2,
2011,  President  Obama  signed  into  law  the  Budget  Control  Act  of  2011,  which,  among  other  things,  created  the  Joint  Select
Committee on Deficit Reduction to recommend to Congress proposals in spending reductions. The Joint Select Committee did not
achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic
reduction  to  several  government  programs.  This  includes  reductions  to  Medicare  payments  to  providers  of  2%  per  fiscal  year,
which went into effect on April 1, 2013, following passage of the Bipartisan Budget Act of 2015, and will stay in effect through
2025 unless Congressional action is taken. On January 2, 2013, President Obama signed into law the American Taxpayer Relief
Act  of  2012,  or  the  ATRA,  which,  among  other  things,  further  reduced  Medicare  payments  to  several  providers,  including
hospitals.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could
limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced
demand for our products or additional pricing pressure.

Intellectual Property

Our intellectual property portfolio consists primarily of trademarks and trade secrets and does not presently consist of

any patents or patent applications. We do not currently intend to file any patent applications in the United States or elsewhere.

Our trademark  portfolio  consists  of five  registered  U.S. trademarks  and six  pending Canadian  trademark  applications.
We  maintain  a  program  to  protect  our  marks  and  will  institute  legal  action  where  necessary  to  prevent  others  from  using  and
registering confusingly similar marks.

In  addition,  to  protect  our  trade  secrets  and  other  intellectual  property  rights,  we  have  entered  into  confidentiality
agreements with third parties, and confidential information and invention assignment agreements with employees, consultants and
advisors. However, there can be no assurance that these measures will be successful in any given case and third parties may still
obtain this information or we may be unable to protect our rights.

Employees

As  of  December  31, 2015  ,  we  had  96 full ‑time  employees.  None  of  our  employees  are  represented  by  a  collective
bargaining  agreement,  and  we  have  never  experienced  any  work  stoppage.  We  believe  we  have  good  relations  with
our employees.

Facilities

Our headquarters located in Santa Barbara, California is approximately 20,000 square feet. The term of the lease for our
headquarters  expires  in  February  2020.  We  also  lease  warehouse  space  located  in  Santa  Barbara,  California,  which  is
approximately 10, 000 square feet .   The term of the lease for our warehouse expire s in January 2019 .

Legal Proceedings

On  September  25,  2015,  a  lawsuit  styled  as  a  class  action  of  our stockholders  was  filed  in  the  United  States  District
Court for the Central District of California. The lawsuit names us and certain of our officers as defendants and alleges violations
of Sections 10(b) and 20(a) of the Exchange Act in connection with allegedly false and misleading statements concerning o ur
business,  operations,  and  prospects.    The  plaintiff  seeks  damages  and  an  award  of  reasonable  costs  and  expenses,  including
attorneys’ fees.  On November 24, 2015, three stockholders (or groups of stockholders) filed motions to appoint lead plaint i ff(s)
and to approve their selection on lead counsel.  On December 10, 2015, the court entered an order appointing lead plaintiffs and
approving their selection of lead counsel.  On February 19, 2016, lead plaintiffs filed their consolidated amended complaint.

On October 28,   November 5, and November 19, 2015, three la wsuits styled as class actions of our stockholders were
filed in the Superior Court of California for the County of San Mateo. The lawsuits name us , certain of our officers and directors,
and the underwriters associated with our follow-on public offering that closed on September 23, 2015 as defendants. The lawsuits
allege  violations  of  Sections  11,  12(a)(2),  and  15  of  the  Securities  Act  in  connection  with  allegedly  false  and  misleading
statements in o ur offering documents associated with the follow-on offering concerning o ur business, operations, and prospects.
The plaintiffs seek damages and an award of reasonable costs and expenses, including attorneys’ fees.   On December 4, 2015,
defendants removed all three lawsuits to the United States District Court for the Northern District of California.  On December 15
and  December  16,  2015,  plaintiffs  filed  motions  to  remand  the  lawsuits  back  to  San  Mateo  Superior  Court  ,  or  Motions  to
Remand.    On  January  19,  2016,  defendants  filed  their  opposition  to  the  Motions  to  Remand,  and  plaintiffs  filed  their  reply  in
support of the Motions to Remand on January 26, 2016. 

It is possible that additional suits will be filed, or allegations made by stockholders, with respect to these same or other
matters and also naming us and/or our officers and directors as defendants. We believe we have meritorious defenses and intend
to  defend  these  lawsuits  vigorously.    Due  to  the  early  stage  of  these  proceedings,      we  are  not  able  to  predict  or  reasonably
estimate the ultimate outcome or possible losses relating to these claims.

Seasonality

We  expect  that,  in  the  future,  our  net  sales  will  fluctuate  on  a  quarterly  basis  due  to  a  variety  of  factors,  including
seasonality  of  breast  augmentation  procedures.  We  believe  that  breast  implant  sales  are  subject  to  seasonal  fluctuation  due  to
breast augmentation patients’ planning their surgery leading up to the summer season and in the period around the winter holiday
season.

Risks Relating to Our Business and Our Industry

We 
currently 
rely 
on 
a 
foreign, 
sole 
source, 
third-party 
to 
manufacture 
and 
supply 
our 
silicone 
gel 
breast 
implants, 
tissue
expanders
and
other
products.

We currently rely on Silimed , our   sole source, third-party manufacturer located in Brazil, to manufacture and supply
our silicone gel breast implants, tissue expanders and other products. Several recent events have occurred which affect our ability
to rely on Silimed as our source for our silicone gel breast implants, tissue expa nders and other products in the short and long
term.

On September 23, 2015, the Medicines and Healthcare Products Regulatory Agency, or the MHRA, an executive agency
of  the  U.K.,  issued  a  press  release  announcing  the  suspension  of  sales  and  implanting  in  U.K  .  of  all  medical  devices
manufactured by Silimed following the suspension of the CE certificate of these products issued by TUV SUD, Silimed’s notified
body  under  EU  regulation.  The  suspension  of  Silimed’s  CE  certificate  by  TUV  SUD  followed  TUV  SUD’s  inspection  at
Silimed’s manufacturing facilities in Brazil, relating to particles on Silimed breast products .

On October 2, 2015, the Brazilian regulatory agency ANVISA and the Department of the Secretary of State of the State
of  Rio  de  Janeiro  announced  that  while  they  continue  to  review  the  technical  compliance  related  to  GMP  of  Silimed’s
manufacturing  facility,  and  as  a  precautionary  measure  ,  they  temporarily  suspended  the  manufacturing  and  shipment  of  all
medical devices made by Silimed, including products manufactured for Sientra. Between October 9, 2015 and March 1, 2016, we
voluntarily  placed  a  temporary  hold  on  the  sale  of  all  Sientra  devices  manufactured  by  Silimed  and  recommended  that  plastic
surgeons discontinue implanting the devices until further notice.  The Company has been in ongoing discussions with the FDA
regarding European and Brazilian regulatory inquiries into Silimed products, and conduct ed its own review of the matter with the
assistance  of  independent  experts  in  quality  management  systems,  GMP  and  data-based  risk  assessment.   After  extensive
independent,  third-party  testing  and  analyses  indicated  no  anticipated  significant  safety  concerns  with  the  use  of  our  products,
including  our  breast  implants,  as  of  March  1,  2016,  we  lifted  the  temporary  hold  on  the  sale  of  our  devices  manufactured  by
Silimed and also sent a letter to our Plastic Surgeons informing them of the Company’s market re-entry plans.

Breast implants have stringent standards for manufacturing and robust quality systems, but there is no specific or defined
standard for particles on breast implants. Each of the FDA, ANVISA and MHRA noted that no risks to patient health have been
identified in connection with implanting Silimed products, and, accordingly, there is no need to adopt any procedure or action for
those  patients  who  have  received  them.  Additionally,  the  FDA  and  ANVISA  indicated  that  that  there  have  been  no  reports  of
adverse events related to th is issue .  

On  January  27,  2016,  after  completing  an  analysis  and  risk  assessment,  ANVISA  announced  their  authoriz  ation  of
Silimed  to  resume  the  commercialization  and  use  of  its  previously  manufactured  products.    ANVISA  concluded  there  was  no
evidence that the presence of surface particles on the silicone implants represented risks which are additional to the ones inherent
in the product.  However, Silimed continues to be suspended from manufacturing and commercializing new batches of implants
until an inspection is performed to reassess the fulfillment of its GMP compliance .    

Additionally, t he suspension of Silimed’s CE certificate by TUV SUD , and the suspension on the commercialization of
Silimed’s products in Europe by the MHRA remains in place and the determination of Silimed’s manufacturing facilities is still
under evaluation, and we cannot predict the outcome of these matter s . The FDA and other U.S. and foreign regulatory agencies
have  substantial  discretion  to  require  additional  testing,  to  impose  restrictions  on  marketed  products  or  on  us,  including  the
withdrawal  or  recall  of  such  products  from  the  market.  If  Silimed  is  unable  to  resume  manufacturing  or  becomes  unwilling  to
manufacture  and  supply  our  silicone  gel  breast  implants,  tissue  expanders  and  other  products,  we  will  not  be  able  to  replace
Silimed quickly, and although we are exploring our strategic alternatives, we have not qualified another manufacturer to source
our implants. 

Even if we were able to identify a replacement manufacturer for our silicone gel breast implants, tissue expanders and
other  products,  the  replacement  manufacturer  would  have  to  be  qualified  with  the  FDA,  which  is  an  expensive  and  time-
consuming  process  during  which  we  may  experience  a  supply  interruption.    There  can  be  no  guarantee  that  Silimed  ,  or  an
alternative manufacturer, will be able to meet our demand to manufacture and supply our products in a timely manner, and as a
result, our financial position and results of operations may be adversely affected.

21

 
Table of Contents

In addition, our reliance on Silimed involves a numbe r of other risks, including that:

·

our  products  may  not  be  manufactured  in  accordance  with  agreed  upon  specifications  or  in  compliance  with
regulatory  requirements,  or  Silimed’s  manufacturing  facilities  may  not  be  able  to  maintain  compliance  with
regulatory  requirements,  which  could  negatively  affect  the  safety  or  efficacy  of  our  products  or  cause  delays  in
shipments of our products;

· we  may  not  be  able  to  timely  respond  to  unanticipated  changes  in  customer  orders,  and  if  orders  do  not  match

forecasts, we may have excess or inadequate inventory of materials and components;

·

our current contract with Silimed expires in less than two years, in 2017, and there can be no assurance that Silimed
will agree to continue to manufacture and supply our products after the expiration of our contract;

· we  may  be  subject  to  price  fluctuations  when  a  supply  contract  is  renegotiated  or  if  our  existing  contract  is  not

renewed;

·

our agreement with Silimed does not permit us to sell the products we obtain from Silimed in any country other than
the United States and Canada;

· we or Silimed may lose access to critical services and components, resulting in an interruption in the manufacture or

shipment of our products;

· we may not be able to find an alternate supplier in a timely manner if the products remain unavailable from Silimed;

· we may be required to obtain regulatory approvals related to any change in our supply chain;

·

·

Silimed may discontinue manufacturing and supplying products to us for risk management reasons; and

Silimed  may  encounter  financial  or  other  hardships  unrelated  to  our  demand  for  products,  which  could  inhibit  its
ability to fulfill our orders and meet our requirements.

Although we have resumed our sale and implanting of devices manufactured by Silimed, t he suspension of the sale and
manufacturing  of  Silimed’s  products  by  foreign  regulatory  agencies,  our  uncertainty  regarding  the  resolution  of  the  regulatory
inquiries  and  the  delay  of  sales  pending  such resolution, and  the  materialization  of  any  other  of  these  risks  could  significantly
increase  our  costs,  our  ability  to  generate  net  sales  would  be  impaired,  market  acceptance  of  our  products  could  be  adversely
affected  and  customers  may  instead  purchase  or  use  our  competitors’  products,  which  could  materially  adversely  and  severely
affect our business, financial condition and results of operations.

Our
sole
source,
third-party
manufacturer,
Silimed,
relies
on
a
sole
source,
third-party
supplier
of
the
medical-grade
silicone
used
in
its
silicone
gel
breast
implants,
tissue
expanders
and
other
products.

Our sole source, third-party manufacturer and supplier, Silimed, relies on Applied Silicone Corporation, or ASC, its sole
source,  third-party  supplier  of  medical-grade  silicone  based  in  Santa  Paula,  California,  for  the  silicone  gel  used  in  its  breast
implants, tissue expanders and other products. If ASC becomes unable or unwilling to supply medical-grade silicone to Silimed,
Silimed  may  not  be  able  to  find  an  alternate  supplier  in  a  timely  manner,  since  the  availability  of  suppliers  of  medical-grade
silicone  is  limited.  In  addition,  ASC  may  discontinue  manufacturing  and  supplying  products  to  Silimed  for  risk  management
reasons,  lose  access  to  critical  services  and  components,  resulting  in  an  interruption  in  the  manufacturing  or  shipment  of  our
products,  or  encounter  financial  or  other  hardships  unrelated  to  Silimed  and  our  demand  for  products,  which  could  inhibit  its
ability  to  fulfill  Silimed’s  orders.  We  may  also  be  required  to  obtain  regulatory  approvals  related  to  any  change  in  our  supply
chain. The materialization of any of these risks could adversely affect our business, financial condition and results of operations.

The
fire
at
one
of
Silimed’s
manufacturing
buildings
may
have
a
severe
impact
on
our
results
of
operations,
financial
position
and
market
share.

On October 22, 2015, there was a fire at one of Silimed’s two manufacturing buildings in Rio de Janeiro, Brazil. The fire
occurred in the building where Sientra’s breast implants are primarily manufactured, or building F2. Silimed has indicated to us
that  a  smaller  production  facility  in  Silimed’s  second  building,  or  building  F1,  which  was  not  impacted  by  the  fire,  has  the
potential  to be modified for breast implant  manufacturing.  In order to commence the manufacturing  of breast implants,  certain
areas in building F1 would need to be reconfigured and receive certification and approval by appropriate regulatory bodies. We
are  working  with  Silimed  to  seek  clarity  as  to  the  near  and  long-term  capabilities  of  Silimed’s  manufacturing  operations,
including the status of equipment that is used to manufacture breast implants and the potential feasibility, production capacity and
timing  related  to  Silimed’s  ability  to  manufacture  our  breast  implants.  The  delay  in  the  manufacturing  of  our  breast  implants
caused  by  the  fire,  our  uncertainty  regarding  when  Silimed’s  facility  will  be  operational  and  able  to  manufacture  our  breast
implants,  and  the  extent  of  the  damage  caused  by  the  fire  may  have  a  severe  impact  on  our  business,  financial  condition  and
results of operations.

We
depend
on
a
positive
reaction
from
our
Plastic
Surgeons
and
their
patients
to
successfully
re-enter
the
market
after
our
voluntary
suspension
of
the
sale
of
Sientra
devices

manufactured
by
Silimed.

On March 1, 2016, we lifted the voluntary temporary hold on sale of all Sientra products manufactured by Silimed and also sent a
letter to our Plastic Surgeons informing them of our market re-entry plans.  Although our market re-entry decision was based on
extensive  and  detailed  independent  third  party  reviews  of  our  finished  goods  inventory,  which  concluded  that  our  implants
continue  to  be  a  safe  choice  for  both  our  surgeons  and  their  patients,  consistent  with  their  FDA  approval  status  in  2012,  we
depend on a positive reception from our Plastic Surgeons and their patients to be able to reestablish the market position we had
prior to the voluntary suspension.  Our re-entry into the market requires us to effectively and responsibly educate accounts on the
results of our testing and reconfirm our strong clinical data, while providing the same high levels of customer service to which our
Plastic Surgeons are accustomed. Our Plastic Surgery Consultants are working diligently to solidify the trust and support of all
our Plastic Surgeons during this important phase of our market re-entry, however, if we are not successful in re-establishing these
relationships,  adapting  our  business  systems,  or  competing  effectively  in  this  market,  our  sales  revenues,  market  share  and
financial performance will be affected negatively.

We
have
incurred
significant
net
operating
losses
since
inception
and
cannot
assure
you
that
we
will
achieve
profitability.

Since  our  inception,  we  have  incurred  significant  net  operating  losses.    As  of  December  31,  2015  ,  we  had  an
accumulated  deficit  of  $175.3 million.    To  date,  we  have  financed  our  operations  primarily  through  sales  of  preferred  stock,
borrowings  under  our  term  loans,  sales  of  our  products  since  2012,  our  initial  public  offering  and  our  recent  follow-on  public
offering of our common stock.  We have devoted substantially all of our resources to the acquisition and clinical development of
our  products,  the  commercial  launch  of  our  products,  the  development  of  a  sales  and  marketing  team  and  the  assembly  of  a
management team to manage our business.

We commenced sales of our breast implants in the second quarter of 2012.  For the year ended   December 31, 2015 ,
our  gross  profit  was  $27.5 million.    However,  although  we  have  achieved  a  positive  gross  profit,  we  had  a  net  loss  of  $41.2
million for the year ended   December 31, 2015 .  The extent of our future operating losses and the timing of profitability  are
uncertain, especially in light of our voluntary hold of the sale of all Sientra devices manufactured by Silimed between October 9,
2015  and  March  1,  2016.  We  will  need  to  generate  significant  sales  to  achieve  profitability,  and  we  might  not  be  able  to  do
so.  Even if we do generate significant sales, we might not be able to achieve, sustain or increase profitability on a quarterly or
annual  basis  in  the  future.    If  our  sales  grow  more  slowly  than  we  have  forecasted,  or  if  our  operating  expenses  exceed  our
forecasts , our financial performance and results of operations will be adversely affected.

Our
future
profitability
depends
on
the
success
of
our
Breast
Products.

Sales of our Breast Products accounted for 98% ,   97% and 97% of our net sales for the year s ended December 31,
2015 ,   2014 and 2013 , respectively.  We expect our net sales to continue to be based primarily on sales of our Breast Products,
and between October 9, 2015 and March 1, 2016, we stopped selling our Breast Products as a result of our voluntary hold on the
sale of all Sientra devices manufactured by Silimed. Our voluntary hold on the sale of Sientra devices

23

 
Table of Contents

manufactured by Silimed, the potential loss of market acceptance of our Breast Products, and any adverse rulings by regulatory
authorities,  including  an  adverse  or  time  consuming  resolution  of  the  current  regulatory  inquiries  regarding  Silimed’s  medical
devices, any adverse publicity  or other adverse  events  relating  to us or  our  Breast  Products,  or the  introduction  of  competitive
products by our competitors and other third parties, may significantly impact our sales and profitability, which would adversely
affect our business, financial condition and results of operations.

Any
negative
publicity
concerning
our
products
could
harm
our
business
and
reputation
and
negatively
impact
our
financial
results.

The  responses  of  potential  patients,  physicians,  the  news  media,  legislative  and  regulatory  bodies  and  others  to
information about complications or alleged complications of our products, including the suspension of Silimed’s CE certificate by
TUV  SUD,  and  the  subsequent  suspension  by  ANVI  SA on  the  manufacturing  and  shipment  of  all  medical  devices  made  by
Silimed,  including  products  manufactured  for  Sientra  while  they  review  the  technical  compliance  related  to  GMP of  Silimed’s
manufacturing facility, could result in negative publicity and could materially reduce market acceptance of our products.  These
responses or any investigations and potential resulting negative publicity may have a material adverse effect on our business and
reputation  and  negatively  impact  our  financial  condition,  results  of  operations  or  the  market  price  of  our  common  stock.    In
addition, significant negative publicity could result in an increased number of product liability claims against us.

There
are
inherent
risks
in
contracting
with
manufacturers
located
outside
of
the
United
States
such
as
in
Brazil.

Silimed is our sole source, third-party manufacturer and its manufacturing plant is located in Brazil.  There are inherent
risks  in  contracting  with  manufacturers  located  outside  of  the  United  States  such  as  in  Brazil,  including  the  risks  of  economic
change,  recession,  labor  strikes  or  disruptions,  political  turmoil,  new  or  changing  tariffs  or  trade  barriers,  new  or  different
restrictions on importing or exporting, civil unrest, infrastructure failure, cultural differences in doing business, lack of contract
enforceability, lack of protection for intellectual property, war and terrorism.  If any of these risks were to materialize, we and
Silimed would both be materially adversely affected and our business, financial condition and results of operations would suffer.

Various 
factors 
outside 
our 
direct 
control 
may 
adversely 
affect 
manufacturing 
and 
supply 
of 
our 
breast 
implants, 
tissue
expanders
and
other
products.

Manufacturing  and  supply  of  our  breast

 products  is  technically
challenging.    Changes  that  our  manufacturer  may  make  outside  the  purview  of  our  direct  control  can  have  an  impact  on  our
processes, on quality and the successful delivery of products to Plastic Surgeons.  Mistakes and mishandling are not uncommon
and can affect production and supply.  Some of these risks include:

 tissue  expanders  and  other

 implants,

·

·

·

·

·

failure of our manufacturer to follow cGMP requirements or mishandling of our products while in production or in
preparation for transit;

transportation and import and export risk, particularly given the global nature of our supply chain;

delays in analytical results or failure of analytical techniques that we depend on for quality control and release of
products;

natural disasters, labor disputes, financial distress, lack of raw material supply, issues with facilities and equipment
or other forms of disruption to business operations affecting our manufacturer or its suppliers; and

latent defects that may become apparent after products have been released and which may result in a recall of such
products.

The materialization of any of these risks could significantly increase our costs, impair our ability to generate net sales,
and adversely  affect  market  acceptance  of our  products  and  customers  may  instead  purchase  or  use our  competitors’  products,
which could materially adversely and severely affect our business, financial condition and results of operations.

We
may
not
realize
the
benefits
of
partnerships
with
other
companies,
acquisitions
of
complementary
products
or
technologies
or
other
strategic
alternatives.

From time to time, we may consider opportunities to partner with or acquire other businesses, products or technologies
that  may  enhance  our  product  platform  or  technology,  expand  the  breadth  of  our  markets  or  customer  base  or  advance  our
business strategies.  Potential partnerships or acquisitions involve numerous risks, including:

·

integration of the acquired products or technologies with our existing business;

· maintenance of uniform standards, procedures, controls and policies;

·

·

·

·

unanticipated costs associated with partnerships or acquisitions;

diversion of management’s attention from our existing business;

uncertainties associated with entering new markets in which we have limited or no experience; and

increased  legal  and  accounting  costs  relating  to  the  partnerships  or  acquisitions  or  compliance  with  regulatory
matters.

We do not know if we will be able to identify partnerships or acquisitions we deem suitable, whether we will be able to
successfully  complete  any  such  partnerships  or  acquisitions  on  favorable  terms  or  at  all,  or  whether  we  will  be  able  to
successfully  integrate  any partnered  or acquired  products  or technologies.   Our potential  inability  to  integrate  any  partnered  or
acquired  products  or  technologies  effectively  or  realize  anticipated  synergies  may  adversely  affect  our  business,  financial
condition and results of operations.

We
have
a
limited
operating
history
and
may
face
difficulties
encountered
by
companies
early
in
their
commercialization
in
competitive
and
rapidly
evolving
markets.

We  commenced  operations  in  2007  and  began  commercializing  silicone  gel  breast  implants  in  the  second  quarter  of
2012.  Accordingly, we have a limited operating history upon which to evaluate our business and forecast our future net sales and
operating  results.    In  assessing  our  business  prospects,  you  should  consider  the  various  risks  and  difficulties  frequently
encountered by companies early in their commercialization in competitive markets, particularly companies that develop and sell
medical devices.  These risks include our ability to:

·

·

·

implement and execute our business strategy;

expand and improve the productivity of our sales force and marketing programs to grow sales of our existing and
proposed products;

increase awareness of our brand and build loyalty among Plastic Surgeons;

· manage expanding operations;

·

·

·

·

·

respond effectively to competitive pressures and developments;

enhance our existing products and develop new products;

obtain regulatory clearance or approval to enhance our existing products and commercialize new products;

perform clinical trials with respect to our existing products and any new products; and

attract, retain and motivate qualified personnel in various areas of our business.

Due to our limited operating history, we may not have the institutional knowledge or experience to be able to effectively

address these and other risks that we may face.  In addition, we may not be able to develop insights into trends

25

 
Table of Contents

that could emerge and negatively affect our business and may fail to respond effectively to those trends.  As a result of these or
other  risks, we may not  be  able  to  execute  key  components  of our  business strategy,  and  our business,  financial  condition  and
operating results may suffer.

If
we
fail
to
compete
effectively
against
our
competitors,
both
of
which
have
significantly
greater
resources
than
we
have,
our
net
sales
and
operating
results
may
be
negatively
affected.

Our industry is intensely competitive and subject to rapid change from the introduction of new products, technologies
and  other  activities  of  industry  participants.    Our  competitors,  Mentor,  a  wholly  owned  subsidiary  of  Johnson  &  Johnson,  and
Allergan  are  well-capitalized  global  pharmaceutical  companies  that  have  been  the  market  leaders  for  many  years  and  have  the
majority share of the breast implant market in the United States.  These competitors also enjoy several competitive advantages
over us, including:

·

·

·

·

·

·

·

greater financial and human resources for sales, marketing and product development;

established relationships with health care providers and third-party payors;

established  reputations  and  name  recognition  among  health  care  providers  and  other  key  opinion  leaders  in  the
plastic surgery industry;

in some cases, an established base of long-time customers;

products supported by long-term clinical data;

larger and more established distribution networks;

greater ability to cross-sell products; and

· more experience  in conducting research  and development,  manufacturing,  performing  clinical  trials  and obtaining

regulatory approval or clearance.

If we fail to compete effectively against our competitors, our net sales and operating results may be negatively affected.

Pricing
pressure
from
customers
and
our
competitors
may
impact
our
ability
to
sell
our
products
at
prices
necessary
to
support
our
current
business
strategies.

Our 2012 entry into the U.S. breast implant market represented a significant expansion of the breast implant choices and
technologies  available  in  the  United  States.    As  a  result  of  our  entry  into  the  U.S.  breast  implant  market,  our  competitors
intensified  competitive  pricing  pressure  for  traditional  round-shaped  breast  implants.    If  we  are  not  successful  in  convincing
customers  or  third-party  payors  of  the  differentiation  of  the  gel  technology  used  in  our  implants  and  selection  of  shapes  and
products as compared to our competitors’ products, third-party payors may not cover or adequately reimburse our products and
customers may choose our competitors’ products.

The
long-term
safety
of
our
products
has
not
fully
been
established
and
our
breast
implants
are
currently
under
study
in
our
PMA
post-approval
studies,
which
could
reveal
unanticipated
complications.

We  currently  market  our  silicone  gel  breast  implants  in  the  United  States.  These  products  have  received  pre-market
approval from the FDA. However, there could still be unanticipated complications or unforeseen health consequences of being
implanted with our silicone gel breast implants over the long-term (defined as 10 years or more). Additionally, we rely on our
clinical  data  to make  favorable  comparisons  of our product  to our competitive  products, and our longer  term  data  may change
over  time.  Further,  future  studies  or  clinical  experience  may  indicate  that  treatment  with  our  products  is  not  differentiated  to
treatment  with  competitive  products.  Such  results  could  slow  the  adoption  of  our  products  and  significantly  reduce  our  sales,
which could prevent us from achieving our forecasted sales targets or achieving or sustaining profitability. Moreover, if long-term
results and experience indicate that our products cause unexpected or

serious complications, we could be subject to mandatory product recalls, suspension or withdrawal of FDA clearance or approval
and significant legal liability.

If
we
are
unable
to
train
Plastic
Surgeons
on
the
safe
and
appropriate
use
of
our
products,
we
may
be
unable
to
achieve
our
expected
growth.

An  important  part  of  our  sales  process  includes  the  ability  to  educate  Plastic  Surgeons  about  the  availability  of
anatomically-shaped breast implants and train Plastic Surgeons on the safe and appropriate use of our products.  If we become
unable to attract potential new Plastic Surgeon customers to our education and training programs, we may be unable to achieve
our expected growth.

There  is  a  learning  process  involved  for  Plastic  Surgeons  to  become  proficient  in  the  use  of  our  anatomically-shaped
products.  It is critical to the success of our commercialization efforts to train a sufficient number of Plastic Surgeons and provide
them  with  adequate  instruction  in  the  appropriate  use  of  our  products  via  preceptorships  and  additional  demonstration
surgeries.  This training process may take longer than expected and may therefore affect our ability to increase sales.  Following
completion  of  training,  we  rely  on  the  trained  Plastic  Surgeons  to  advocate  the  benefits  of  our  products  in  the
marketplace.  Convincing Plastic Surgeons to dedicate the time and energy necessary for adequate training is challenging, and we
cannot assure you that we will be successful in these efforts.  If Plastic Surgeons are not properly trained, they may misuse or
ineffectively  use  our  products.    This  may  also  result  in,  among  other  things,  unsatisfactory  patient  outcomes,  patient  injury,
negative publicity or lawsuits against us, any of which could have an adverse effect on our business and reputation.

If
we
are
unable
to
continue
to
enhance
our
existing
Breast
Products
and
develop
and
market
new
products
that
respond
to
customer
needs
and
preferences
and
achieve
market
acceptance,
we
may
experience
a
decrease
in
demand
for
our
products
and
our
business
could
suffer.

We may not be able to compete effectively with our competitors, and ultimately satisfy the needs and preferences of our
customers,  unless  we  can  continue  to  enhance  existing  products  and  develop  and  market  new  innovative  products.    Product
development requires the investment of significant financial, technological and other resources.  Product improvements and new
product  introductions  also  require  significant  planning,  design,  development  and  testing  at  the  technological,  product  and
manufacturing  process  levels  and  we  may  not  be  able  to  timely  develop  product  improvements  or  new  products.    Our
competitors’ new products may beat our products to market, be more effective with new features, obtain better market acceptance
or render our products obsolete.  Any new or modified products that we develop may not receive clearance or approval from the
FDA, or achieve market acceptance or otherwise generate any meaningful sales or profits for us relative to our expectations based
on,  among  other  things,  existing  and  anticipated  investments  in  manufacturing  capacity  and  commitments  to  fund  advertising,
marketing, promotional programs and research and development.

If 
changes 
in 
the 
economy 
and 
consumer 
spending, 
reduce 
consumer 
demand 
for 
our 
products, 
our 
sales 
and 
profitability
would
suffer.

We are subject to the risks arising from adverse changes in general economic and market conditions.  Certain elective
procedures, such as breast augmentation  and body contouring, are typically not covered by insurance.   Adverse changes in the
economy may cause consumers to reassess their spending choices and reduce the demand for these surgeries and could have an
adverse  effect  on  consumer  spending.    This  shift  could  have  an  adverse  effect  on  our  net  sales.    Furthermore,  consumer
preferences  and trends may shift due to a variety of factors, including changes in demographic and social trends, public health
initiatives and product innovations, which may reduce consumer demand for our products.

We
are
required
to
maintain
high
levels
of
inventory,
which
could
consume
a
significant
amount
of
our
resources
and
reduce
our
cash
flows.

We  need  to  maintain  substantial  levels  of  inventory  to  protect  ourselves  from  supply  interruptions,  provide  our
customers with a wide range of shapes and sizes of our breast implants, and account for the high return rates we experience as
Plastic Surgeons typically order our products in multiple sizes for a single surgery and then return what they do not use.  As a
result of our substantial inventory levels, we are subject to the risk that a substantial portion of our inventory becomes obsolete. T
he materialization of any of these risks may have a material adverse effect on our earnings and cash flows due to the resulting
costs associated with the inventory impairment charges and costs required to replace such inventory . 

27

Additionally, the suspension of Silimed’s manufacturing by ANVISA, the recent fire at Silimed’s facility that manufactures our
breast  implants,  including  the  status  of  equipment  that  is  used  to  manufacture  such  implants  and  the  potential  feasibility,
production capacity and timing related to Silimed’s ability to manufacture breast implants in other facilities,   or our ability to find
an alternate supplier in a timely manner, may affect our ability to maintain the level of inventory supply  we require  to protect
ourselves from supply interruptions which could have an unfavorable i mpact on our net sales .

Any
disruption
at
our
facilities
could
adversely
affect
our
business
and
operating
results.

Our principal offices are located in Santa Barbara, California.  Substantially all of our operations are conducted at this
location,  including  customer  service,  development  and  management  and  administr  ative  functions.    S  ubstantially  all  of  our
inventory  of  finished  goods  is  held  at  a  second  location  in  Santa  Barbara,  California.    Despite  our  efforts  to  safeguard  our
facilities,  including  acquiring  insurance,  adopting  health  and  safety  protocols  and  utilizing  off-site  storage  of  computer  data,
vandalism, terrorism or a natural or other disaster, such as an earthquake, fire or flood, could damage or destroy our inventory of
finished goods, cause substantial delays in our operations, result in the loss of key information and cause us to incur additional
expenses.    Our  insurance  may  not  cover  our  losses  in  any  particular  case.    In  addition,  regardless  of  the  level  of  insurance
coverage, damage to our facilities may have a material adverse effect on our business, financial condition and operating results.

If 
there 
are 
significant 
disruptions 
in 
our 
information 
technology 
systems, 
our 
business, 
financial 
condition 
and 
operating
results
could
be
adversely
affected.

The  efficient  operation  of  our  business  depends  on  our  information  technology  systems.    We  rely  on  our  information
technology  systems  to  effectively  manage  sales  and  marketing  data,  accounting  and  financial  functions,  inventory,  product
development tasks, clinical data, and customer service and technical support functions.  Our information technology systems are
vulnerable to damage or interruption from earthquakes, fires, floods and other natural disasters, terrorist attacks, computer viruses
or hackers, power losses, and computer system or data network failures.  In addition, a variety of our software systems are cloud-
based data management applications hosted by third-party service providers whose security and information technology systems
are subject to similar risks.

The  failure  of  our  or  our  service  providers’  information  technology  could  disrupt  our  entire  operation  or  result  in
decreased  sales,  increased  overhead  costs  and  product  shortages,  all  of  which  could  have  a  material  adverse  effect  on  our
reputation, business, financial condition and operating results.

We 
may 
be 
adversely 
affected 
by 
earthquakes 
or 
other 
natural 
disasters 
and 
our 
business 
continuity 
and 
disaster 
recovery
plans
may
not
adequately
protect
us
from
a
serious
disaster.

Our  corporate  headquarters  and  other  facilities  are  located  in  Santa  Barbara,  California,  which  in  the  past  has
experienced  both  severe  earthquakes  and  wildfires.    We  do  not  carry  earthquake  insurance.    Earthquakes,  wildfires  or  other
natural disasters could severely disrupt our operations, and have a material adverse effect on our business, results of operations,
financial condition and prospects.

If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our
headquarters,  that  damaged  critical  infrastructure,  such  as  our  enterprise  financial  systems  or  manufacturing  resource  planning
and enterprise quality systems, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to
continue  our  business  for  a  substantial  period  of  time.    The  disaster  recovery  and  business  continuity  plans  we  have  in  place
currently  are  limited  and  are  unlikely  to  prove  adequate  in  the  event  of  a  serious  disaster  or  similar  event.    We  may  incur
substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which, particularly
when taken together with our lack of earthquake insurance, could have a material adverse effect on our business.

Failure
to
obtain
hospital
or
group
purchasing
organization
contracts
could
have
a
material
adverse
effect
on
our
financial
condition
and
operating
results.

A portion of our net sales is derived from sales to hospitals.  Many hospital customers, through the contracting process,
limit  the  number  of  breast  implant  suppliers  that  may  sell  to  their  institution.    Hospitals  may  choose  to  contract  with  our
competitors who have a broader range of products that can be used in a wider variety of procedures or our

28

 
Table of Contents

competitors  may  actively  position  their  broader  product  portfolios  against  us  during  the  hospital  contracting  process.    Any
limitations on the number of hospitals to which we can sell our products may significantly restrict our ability to grow.

In addition, contracts  with hospitals  and group purchasing  organizations,  or GPOs, often have complex insurance  and
indemnification requirements, which may not be beneficial to us, or we may not be able to successfully negotiate contracts with a
substantial  number  of  hospitals  and  GPOs  at  all,  which  could  adversely  affect  our  business,  financial  condition  and  results  of
operations.

Our 
business 
could 
suffer 
if 
we 
lose 
the 
services 
of 
key 
personnel 
or 
are 
unable 
to 
attract 
and 
retain 
additional 
qualified
personnel.

We are dependent upon the continued services of key personnel, including members of our executive management team
who  have  extensive  experience  in  our  industry.  The  loss  of  any  one  of  these  individuals  could  disrupt  our  operations  or  our
strategic  plans.  On  November  12,  2015,  Hani  Zeini  stepped  down  as  our  President  and  Chief  Executive  Officer  and  Jeffrey
Nugent was appointed as our Chairman and Chief Executive Officer. On February 16, 2016, Mr. Zeini resigned from our board of
director s .  The announcement of the departure of Mr. Zeini from our board and as President and Chief Executive Officer may
have  a  negative  effect  on  employee  morale  and  on  our  customer  relationships  which  is  potentially  mitigated  by his  continuing
consultancy with the Company. Additionally,  our future success will depend on, among other things, our ability to continue to
hire  and  retain  the  necessary  qualified  sales,  marketing  and  managerial  personnel,  for whom we compete  with  numerous  other
companies, academic institutions and organizations. If we lose additional key employees, if we are unable to attract or retain other
qualified personnel, or if our management team is not able to effectively manage us through these events, our business, financial
condition, and results of operations may be adversely affected.

We
will
need
to
increase
the
size
of
our
organization,
and
we
may
experience
difficulties
in
managing
growth.

As  of  December  31, 2015  ,  we  had  approximately  96 full-time  employees.    Our  management  and  personnel,  and  the
systems and facilities we currently have in place, may not be adequate to support future growth.  Effectively executing our growth
strategy  requires  that  we  increase  net  sales  through  sales  and  marketing  activities,  recruit  and  retain  additional  employees  and
continue to improve our operational, financial and management controls, reporting systems and procedures. If we are not able to
effectively  expand  our  organization  in  these  ways,  we  may  not  be  able  to  successfully  execute  our  growth  strategy,  and  our
business, financial condition and results of operations may suffer.

Risks Related to Our Financial Results

Our
quarterly
net
sales
and
operating
results
are
unpredictable
and
may
fluctuate
significantly
from
quarter
to
quarter
due
to
factors 
outside 
our 
control, 
which 
could 
adversely 
affect 
our 
business, 
results 
of 
operations 
and 
the 
trading 
price 
of 
our
common
stock.

Our net sales and operating results may vary significantly from quarter to quarter and year to year due to a number of
factors,  many of which are outside of our control and any of which may cause our stock price to fluctuate.   Our net sales and
results of operations will be affected by numerous factors, including:

·

·

·

·

·

the length of time that Silimed is unable to manufacture our Breast Products as a result of ANIVSA’s suspension of
the manufacturing operations and the fire at Silimed’s facility;

the  timing  and  availability  of  alternative  manufacturing  sources  to  supply  our  silicone  gel  breast  implants,  tissue
expanders and other products;

the impact of the buying patterns of patients and seasonal cycles in consumer spending;

our ability to drive increased sales of anatomically-shaped breast implants products;

our ability to establish and maintain an effective and dedicated sales organization;

29

·

pricing pressure applicable to our products, including adverse third-party coverage and reimbursement outcomes;

results of clinical research and trials on our existing products;

the impact of the recent regulatory inquiries of Silimed’s medical devices on our brand and reputation;

timing of our research and development activities and initiatives;

the mix of our products sold due to different profit margins among our products;

timing of new product offerings, acquisitions, licenses or other significant events by us or our competitors;

the ability of our suppliers to timely provide us with an adequate supply of products;

the evolving product offerings of our competitors;

regulatory approvals and legislative changes affecting the products we may offer or those of our competitors;

increased labor and related costs;

interruption in the manufacturing or distribution of our products;

the effect of competing technological, industry and market developments;

changes in our ability to obtain regulatory clearance or approval for our products; and

our ability to expand the geographic reach of our sales and marketing efforts.

Many of the products we may seek to develop and introduce in the future will require FDA approval or clearance before
commercialization in the United States, and commercialization of such products outside of the United States would likely require
additional  regulatory  approvals,  CE  Certificates  of  Conformity  and  import  licenses.    As  a  result,  it  will  be  difficult  for  us  to
forecast demand for these products with any degree of certainty.  In addition, we will be increasing our operating expenses as we
expand our commercial capabilities.  Accordingly, we may experience significant, unanticipated quarterly losses.  If our quarterly
or annual operating results fall below the expectations of investors or securities analysts, the price of our common stock could
decline substantially.  Furthermore, any quarterly or annual fluctuations in our operating results may, in turn, cause the price of
our common stock to fluctuate substantially.  We believe that quarterly comparisons of our financial results are not necessarily
meaningful and should not be relied upon as an indication of our future performance.

Our
future
capital
needs
are
uncertain
and
we
may
need
to
raise
additional
funds
in
the
future,
and
these
funds
may
not
be
available
on
acceptable
terms
or
at
all.

As of December 31, 2015 , we had $112.8 million in cash and cash equivalents.  We believe that our available cash on
hand will be sufficient to satisfy our liquidity requirements for at least the next 12 months.  However, the continued growth of our
business,  including  the  expansion  of  our  sales  force  and  marketing  programs,  and  research  and  development  activities,  will
significantly increase our expenses.  In addition, we expect that the recent events involving Silimed, including our voluntary hold
on  the  sale  and  implanting  of  all  Sientra  devices  manufactured  by  Silimed  between  October  9,  2015  and  March  1,  2016,  our
uncertainty  regarding  the  amount  of  additional  expenses  we  may  incur  in  connection  with  regulatory  inquiries  and  our  own
review and testing, as well as expenses we may incur in connection with reestablishing our inventory supply as a result of the fire
in Silimed’s manufacturing facility and expenses we may incur defending against litigation claims, may have a material effect our
future cash outflows and Sientra’s liquidity. Additionally, following our repayment of all principal, interest, other amounts and
obligations  owed  to  Oxford  Finance  LLC,  or  Oxford,  under  the  term  loans  for  a  total  of  $24.5  million,  the  Company  has  no
outstanding debt obligations.

30

 
Table of Contents

Our future capital requirements will depend on many factors, including:

·

·

·

·

·

·

·

·

·

·

·

our continued ability to rely on Silimed to manufacture and supply our silicone gel breast implants, tissue expanders
and other products or the timing and availability of alternative manufacturing sources ;

net sales generated by our silicone gel breast implants and tissue expanders and any other future products that we
may develop and commercialize;

expenses we incur in connection with potential litigation or governmental investigations;

costs associated with our own review and testing at Silimed’s manufacturing facilities and of our own inventory;

costs associated with expanding our sales force and marketing programs;

cost associated with developing and commercializing our proposed products or technologies;

cost of obtaining and maintaining regulatory clearance or approval for our current or future products;

cost of ongoing compliance with regulatory requirements;

expenses  we  incur  in  connection  with  defending  against  the  lawsuit  filed  against  us  and  certain  of  our  officers
alleging  violations  of  Sections  10(b)  and  20(a)  of  the  Exchange  Act  in  connection  with  allegedly  false  and
misleading statements concerning Sientra’s business, operations, and prospects;

anticipated or unanticipated capital expenditures; and

unanticipated general and administrative expenses.

As  a  result  of  these  and  other  factors,  we  do  not  know  whether  and  the  extent  to  which  we  may  be  required  to  raise
additional capital.  We may in the future seek additional capital from public or private offerings of our capital stock, borrowings
under term loans or other sources.  If we issue equity or debt securities to raise additional funds, our existing stockholders may
experience  dilution,  and  the  new  equity  or  debt  securities  may  have  rights,  preferences  and  privileges  senior  to  those  of  our
existing  stockholders.    In  addition,  if  we  raise  additional  funds  through  collaborations,  licensing,  joint  ventures,  strategic
alliances,  partnership  arrangements  or  other  similar  arrangements,  it  may  be  necessary  to  relinquish  valuable  rights  to  our
potential future products or proprietary technologies, or grant licenses on terms that are not favorable to us.

If  we  are  unable  to  raise  additional  capital,  we  may  not  be  able  to  expand  our  sales  force  and  marketing  programs,
enhance  our  current  products  or  develop  new  products,  take  advantage  of  future  opportunities,  or  respond  to  competitive
pressures, changes in supplier relationships, or unanticipated changes in customer demand.  Any of these events could adversely
affect  our  ability  to  achieve  our  strategic  objectives,  which  could  have  a  material  adverse  effect  on  our  business,  financial
condition and operating results.

Our
ability
to
use
net
operating
losses
to
offset
future
taxable
income
may
be
subject
to
certain
limitations.

As of December 31, 2015 , we had federal net operating loss carryforwards, or NOLs, of approximately $137.8 million,
which expire in various years beginning in 2027, if not utilized to offset taxable income.  In general, under Section 382 of the
Internal  Revenue  Code  of  1986,  as  amended,  or  the  Code,  a  corporation  that  undergoes  an  “ownership  change”  is  subject  to
limitations on its ability to utilize its pre-change NOLs to offset future taxable income.  In general, an “ownership change” occurs
if there is a cumulative change in our ownership by “5% shareholders” that exceeds 50 percentage points over a rolling three-year
period.    Our  existing  NOLs  may  be  subject  to  limitations  arising  from  previous  ownership  changes,  and  if  we  undergo  one  or
more ownership changes in connection with future transactions in our stock, our ability to utilize NOLs could be further limited
by  Section  382  of  the  Code.    As  a  result  of  these  limitations,  we  may  not  be  able  to  utilize  a  material  portion  of  the  NOLs
reflected on our balance sheet and for this reason, we have fully reserved against the value of our NOLs on our balance sheet. We
have not completed a Section 382 analysis to determine

31

 
Table of Contents

if  an  ownership  change  has  occurred.  Until  such  analysis  is  completed,  we  cannot  be  sure  that  the  full  amount  of  the  existing
federal NOLs will be available to us, even if we do generate taxable income before their expiration.

Future
changes
in
financial
accounting
standards
may
cause
adverse
unexpected
net
sales
or
expense
fluctuations
and
affect
our
reported
results
of
operations.

A  change  in  accounting  standards  could  have  a  significant  effect  on  our  reported  results  and  may  even  affect  our
reporting of transactions completed before the change is effective.  New pronouncements and varying interpretations of existing
pronouncements have occurred and may occur in the future.  Changes to existing rules or current practices may adversely affect
our reported financial results of our business.

Risks Related to Our Intellectual Property and Potential Litigation

If 
our 
intellectual 
property 
rights 
do 
not 
adequately 
protect 
our 
products 
or 
technologies, 
others 
could 
compete 
against 
us
more
directly,
which
would
hurt
our
profitability.

Our success depends in part on our ability to protect our intellectual property rights.  Our intellectual property portfolio
consists of no patents or patent applications, and we do not currently plan to file for patent protection in the future, in the United
States or elsewhere.  We instead rely on trade secrets, proprietary know-how and regulatory barriers to protect our products and
technologies and seek protection of our rights, in part, through confidentiality and proprietary information agreements.  However,
these  agreements  may  not  provide  sufficient  protection  or  adequate  remedies  for  violation  of  our  rights  in  the  event  of
unauthorized use or disclosure of confidential and proprietary information.  Without additional protection under the patent laws,
such unauthorized use or disclosure may enable competitors to duplicate or surpass our technological achievements.  Moreover,
the laws of certain foreign countries do not recognize intellectual property rights or protect them to the same extent as do the laws
of the United States.  Failure to protect our proprietary rights could seriously impair our competitive position.

The
medical
device
industry
is
characterized
by
patent
litigation
and
we
could
become
subject
to
litigation
that
could
be
costly,
result
in
the
diversion
of
management’s
time
and
efforts,
require
us
to
pay
damages
or
prevent
us
from
marketing
our
existing
or
future
products.

Our  commercial  success  will  depend  in  part  on  not  infringing  the  patents  or  violating  the  other  proprietary  rights  of
others.  Significant litigation regarding patent rights occurs in our industry.  Our competitors in both the United States and abroad,
many  of  which  have  substantially  greater  resources  and  have  made  substantial  investments  in  patent  portfolios  and  competing
technologies,  may  have  applied  for  or  obtained  or  may  in  the  future  apply  for  and  obtain,  patents  that  will  prevent,  limit  or
otherwise  interfere  with  our  ability  to  make,  use  and  sell  our  products.    Generally,  we  do  not  conduct  independent  reviews  of
patents issued to third parties.  We may not be aware of whether our products do or will infringe existing or future patents.  In
addition, patent applications in the United States and elsewhere can be pending for many years, and may be confidential for 18
months or more after filing, and because pending patent claims can be revised before issuance, there may be applications of others
now pending of which we are unaware that may later result in issued patents that will prevent, limit or otherwise interfere with
our ability to make, use or sell our products.  We may not be aware of patents that have already issued that a third party might
assert  are  infringed  by  our  products.    It  is  also  possible  that  patents  of  which  we  are  aware,  but  which  we  do  not  believe  are
relevant to our product candidates, could nevertheless be found to be infringed by our products.  The large number of patents, the
rapid rate of new patent applications and issuances, the complexities of the technology involved and the uncertainty of litigation
increase the risk of business assets and management’s attention being diverted to patent litigation.  In the future, we may receive
communications from various industry participants alleging our infringement of their patents, trade secrets or other intellectual
property rights and/or offering licenses to such intellectual property.  Any lawsuits resulting from such allegations could subject
us  to  significant  liability  for  damages  and  invalidate  our  proprietary  rights,  even  if  they  lack  merit.    Any  potential  intellectual
property litigation also could force us to do one or more of the following:

·

·

stop making, selling or using products or technologies that allegedly infringe the asserted intellectual property;

lose  the  opportunity  to  license  our  technology  to  others  or  to  collect  royalty  payments  based  upon  successful
protection and assertion of our intellectual property rights against others;

32

 
Table of Contents

·

·

·

·

·

incur significant legal expenses;

pay  substantial  damages  or  royalties  to  the  party  whose  intellectual  property  rights  we  may  be  found  to  be
infringing;

pay the attorney fees and costs of litigation to the party whose intellectual property rights we may be found to be
infringing;

redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive
and/or infeasible; or

attempt  to  obtain  a  license  to  the  relevant  intellectual  property  from  third  parties,  which  may  not  be  available  on
reasonable terms or at all.

Any litigation or claim against us, even those without merit, may cause us to incur substantial costs, and could place a
significant  strain  on  our  financial  resources,  divert  the  attention  of  management  from  our  core  business  and  harm  our
reputation.    If  we  are  found  to  infringe  the  intellectual  property  rights  of  third  parties,  we  could  be  required  to  pay  substantial
damages  (which  may  be  increased  up  to  three  times  of  awarded  damages)  and/or  substantial  royalties  and  could  be  prevented
from selling our products unless we obtain a license or are able to redesign our products to avoid infringement.  Any such license
may not be available on reasonable terms, if at all, and there can be no assurance that we would be able to redesign our products
in a way that would not infringe the intellectual property rights of others.  If we fail to obtain any required licenses or make any
necessary changes to our products or technologies, we may have to withdraw existing products from the market or may be unable
to  commercialize  one  or  more  of  our  products,  all  of  which  could  have  a  material  adverse  effect  on  our  business,  results  of
operations and financial condition.

In addition, we generally indemnify our customers with respect to infringement by our products of the proprietary rights
of third parties.  Third parties may assert infringement claims against our customers.  These claims may require us to initiate or
defend protracted and costly litigation on behalf of our customers, regardless of the merits of these claims. If any of these claims
succeed, we may be forced to pay damages on behalf of our customers or may be required to obtain licenses for the products they
use.  If we cannot obtain all necessary licenses on commercially reasonable terms, our customers may be forced to stop using our
products.

We
may

from
claims

we
or
our

of
non-competition
or
non-solicitation
agreements
with
our
competitors.

Many  of  our  employees  were  previously  employed  at  other  medical  device  companies,  including  our  competitors  or
potential competitors, in some cases until recently.  We have been the subject of and may, in the future, be subject to claims that
we,  our  employees  have  inadvertently  or  otherwise  used  or  disclosed  alleged  trade  secrets  or  other  proprietary  information  of
these former employers or competitors.  In addition, we have been and may in the future be subject to claims that we caused an
employee to breach the terms of his or her non-competition or non-solicitation agreement.  Litigation may be necessary to defend
against these claims.  Even if we are successful in defending against these claims, litigation could result in substantial costs and
could be a distraction to management.  If our defense to those claims fails, in addition to paying monetary damages, we may lose
valuable  intellectual  property  rights  or  personnel.    Any  litigation  or  the  threat  thereof  may  adversely  affect  our  ability  to  hire
employees.    A  loss  of  key  personnel  or  their  work  product  could  hamper  or  prevent  our  ability  to  commercialize  product
candidates, which could have an adverse effect on our business, results of operations and financial condition.

We
may
be
subject
to
substantial
warranty
or
product
liability
claims
or
other
litigation
in
the
ordinary
course
of
business
that
may
adversely
affect
our
business,
financial
condition
and
operating
results.

As a supplier of medical devices, we may be subject to substantial warranty or product liability claims alleging that the
use of our products has resulted in adverse health effects or other litigation in the ordinary course of business that may require us
to make  significant  expenditures  to defend  these claims  or pay damage  awards.  The breast implant  industry has a particularly
significant history of product liability litigation. The risks of litigation exist even with respect to products that have received or in
the future may receive regulatory approval for commercial sale, such as our Breast Products.  In addition, our silicone gel breast
implants are sold with a warranty providing for no-charge replacement implants in the

33

 
Table of Contents

event of certain ruptures that occur any time during the life of the patient and this warranty also includes cash payments to offset
surgical fees if the rupture occurs within 10 years of implantation.

We  maintain  product  liability  insurance,  but  this  insurance  is  limited  in  amount  and  subject  to  significant
deductibles.    There  is  no  guarantee  that  insurance  will  be  available  or  adequate  to  protect  against  all  claims.    Our  insurance
policies are subject to annual renewal and we may not be able to obtain liability insurance in the future on acceptable terms or at
all.  In addition, our insurance premiums could be subject to increases in the future, which may be material.  If the coverage limits
are inadequate to cover our liabilities or our insurance costs continue to increase as a result of warranty or product liability claims
or other litigation, then our business, financial condition and operating results may be adversely affected.

Fluctuations
in
insurance
cost
and
availability
could
adversely
affect
our
profitability
or
our
risk
management
profile.

We hold a number of insurance policies, including product liability insurance, directors’ and officers’ liability insurance,
general  liability  insurance,  property  insurance,  employment  practices,  and  workers’  compensation  insurance.    If  the  costs  of
maintaining adequate insurance coverage increase significantly in the future, our operating results could be materially adversely
affected.    Likewise,  if  any  of  our  current  insurance  coverage  should  become  unavailable  to  us  or  become  economically
impractical, we would be required to operate our business without indemnity from commercial insurance providers.  If we operate
our  business  without  insurance,  we  could  be  responsible  for  paying  claims  or  judgments  against  us  that  would  have  otherwise
been covered by insurance, which could adversely affect our results of operations or financial condition.

Risks Related to Our Legal and Regulatory Environment

We
are
subject
to
extensive
federal
and
state
healthcare
regulation,
and
if
we
fail
to
comply
with
applicable
regulations,
we
could
suffer
severe
criminal
or

sanctions
or
be
required
to

As a device manufacturer, even though we do not control referrals or bill directly to Medicare, Medicaid or other third-
party payors, we are subject to healthcare fraud and abuse regulation and enforcement by the federal government and the states in
which we conduct our business, as well as other healthcare laws and regulations.  The healthcare laws and regulations that may
affect our ability to operate include:

·

·

·

·

the  federal  Anti-Kickback  Statute,  which  applies  to  our  business  activities,  including  our  marketing  practices,
educational  programs,  pricing  policies  and  relationships  with  healthcare  providers,  by  prohibiting,  among  other
things, knowingly and willfully soliciting, receiving, offering or providing any remuneration (including any bribe,
kickback or rebate) directly or indirectly, overtly or covertly, in cash or in kind, intended to induce or in return for
the  purchase  or  recommendation  of  any  good,  facility,  item  or  service  reimbursable,  in  whole  or  in  part,  under  a
federal healthcare program, such as the Medicare or Medicaid programs. A person or entity does not need to have
actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it in order to commit a violation.  
In  addition,  following  passage  of  the  PPACA  violations  of  the  federal  Anti-Kickback  Statute  became  per  se
violations of the False Claims Act;

federal civil and criminal false claims laws and civil monetary penalty laws, including the federal civil False Claims
Act,  or  FCA,  that  prohibit,  among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  claims  for
payment  from  Medicare,  Medicaid  or  other  government  payors  that  are  false  or  fraudulent,  or  making  a  false
statement material to an obligation to pay or transmit money or property to the federal government, and which may
apply to entities that provide coding and billing advice to customers;

the  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  and  its  implementing
regulations,  which  created  additional  federal  criminal  laws  that  prohibit,  among  other  things,  knowingly  and
willfully executing, or attempting to execute a scheme to defraud any healthcare benefit program or making false
statements relating to healthcare matters ;

and,  HIPAA,  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  or  the
HITECH Act, also imposes certain regulatory and contractual requirements on certain types of people and entities
regarding the privacy, security and transmission of individually identifiable health information;

34

 
Table of Contents

·

·

the federal Physician Payments Sunshine Act, enacted under the PPACA, which requires certain manufacturers of
drugs,  devices,  biologics,  and  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid,  or  the
Children’s Health Insurance Program, with specific exceptions, to make annual reports to the Centers for Medicare
&  Medicaid  Services,  or  CMS,  regarding  any  “transfers  of  value”  provided  to  physicians  and  teaching  hospitals.
Failure to submit required information may result in civil monetary penalties of up to an aggregate of $150,000 per
year and up to an aggregate of $1 million per year for “knowing failures,” for all payments, transfers of value or
ownership or investment interests that are not timely, accurately, and completely reported in an annual submission.
We are required to report detailed payment data and submit legal attestation to the accuracy of such data by March
31st of each calendar year; and

state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws that may apply
to  items  or  services  reimbursed  by  any  third-party  payor,  including  commercial  insurers;  state  laws  that  require
device  companies  to  comply  with  the  industry’s  voluntary  compliance  guidelines  and  the  relevant  compliance
guidance promulgated by the federal government or otherwise restrict payments that may be provided to healthcare
providers  and  entities;  state  laws  that  require  device  manufacturers  to  report  information  related  to  payments  and
other  transfers  of  value  to  physicians  and  other  healthcare  providers  and  entities  or  marketing  expenditures;  and
state laws governing the privacy and security of certain health information, many of which differ from each other in
significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Because of the breadth of these laws, it is possible that some of our business activities, including our relationships with
physicians and other health care providers and entities, some of whom recommend, purchase and/or prescribe our products, could
be subject to challenge under one or more of such laws.  Any action against us for violation of these laws, even if we successfully
defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of
our  business.    If  our  operations  are  found  to  be  in  violation  of  any  of  the  laws  described  above  or  any  other  governmental
regulations  that  apply to  us, we may  be subject  to penalties,  including,  without limitation,  administrative,  civil  and/or  criminal
penalties,  damages,  fines,  disgorgement,  contractual  damages,  reputational  harm,  exclusion  from  governmental  health  care
programs,  diminished  profits  and  future  earnings,  and  the  curtailment  or  restructuring  of  our  operations,  any  of  which  could
adversely affect our ability to operate our business and our financial results.

Our
medical
device 
products
and
operations
are
subject
to
extensive
governmental
regulation
both
in
the
United
States
and
abroad,
and
our
failure
to
comply
with
applicable
requirements
could
cause
our
business
to
suffer.

Our medical device products and operations are subject to extensive regulation by the FDA and various other federal,
state and foreign governmental authorities, such as Health Canada.  Government regulation of medical devices is meant to assure
their safety and effectiveness, and includes regulation of, among other things:

·

·

·

·

design, development and manufacturing;

testing, labeling, content and language of instructions for use and storage;

clinical trials;

product safety;

· marketing, sales and distribution;

·

·

·

·

regulatory clearances and approvals including pre-market clearance and approval;

conformity assessment procedures;

product traceability and record keeping procedures;

advertising and promotion;

35

 
Table of Contents

·

·

·

·

product complaints, complaint reporting, recalls and field safety corrective actions;

post-market  surveillance,  including  reporting  of  deaths  or  serious  injuries  and  malfunctions  that,  if  they  were  to
recur, could lead to death or serious injury;

post-market studies; and

product import and export.

The regulations to which we are subject are complex and have tended to become more stringent over time.  Regulatory
changes could result in restrictions on our ability to carry on or expand our operations, higher than anticipated costs or lower than
anticipated sales.

Before we can market or sell a new regulated product or a significant modification to an existing product in the United
States,  we  must  obtain  either  clearance  under  Section  510(k)  of  the  Federal  Food,  Drug  and  Cosmetic  Act,  or  FDCA,  or  an
approval of a pre-market approval, or PMA, application unless the device is specifically exempt from pre-market review.  In the
510(k) clearance process, the FDA must determine that a proposed device is “substantially equivalent” to a device legally on the
market, known as a “predicate” device, with respect to intended use, technology and safety and effectiveness, in order to clear the
proposed  device  for  marketing.    Clinical  data  is  sometimes  required  to  support  substantial  equivalence.    In  the  PMA  approval
process, the FDA must determine that a proposed device is safe and effective for its intended use based, in part, on extensive data,
including, but not limited to, technical, pre-clinical, clinical trial, manufacturing and labeling data.  The PMA process is typically
required  for  devices  for  which  the  510(k)  process  cannot  be  used  and  that  are  deemed  to  pose  the  greatest  risk,  such  as  life-
sustaining,  life-supporting  or  implantable  devices.    Modifications  to  products  that  are  approved  through  a  PMA  application
generally  need  FDA  approval.    Similarly,  some  modifications  made  to  products  cleared  through  a  510(k)  may  require  a  new
510(k).    The  FDA’s  510(k)  clearance  process  usually  takes  from  three  to  12  months,  but  may  last  longer.    The  process  of
obtaining  a  PMA  is  much  more  costly  and  uncertain  than  the  510(k)  clearance  process  and  generally  takes  from  one  to  three
years, or even longer, from the time the application is submitted to the FDA until an approval is obtained.

In the United States, our silicone gel breast implants are marketed pursuant to a PMA order issued by the FDA in March
2012, and our tissue expanders are marketed pursuant to pre-market clearance under Section 510(k) of the FDCA.  If the FDA
requires us to go through a lengthier, more rigorous examination for future products or modifications to existing products than we
had  expected,  our  product  introductions  or  modifications  could  be  delayed  or  canceled,  which  could  cause  our  sales  to
decline.  The FDA may demand that we obtain a PMA prior to marketing certain of our future products.  In addition, if the FDA
disagrees  with  our  determination  that  a  product  we  market  is  subject  to  an  exemption  from  pre-market  review,  the  FDA  may
require  us  to  submit  a  510(k)  or  PMA  in  order  to  continue  marketing  the  product.    Further,  even  with  respect  to  those  future
products where a PMA is not required, we cannot assure you that we will be able to obtain the 510(k) clearances with respect to
those products.

The FDA can delay, limit or deny clearance or approval of a device for many reasons, including:

· we  may  not  be  able  to  demonstrate  to  the  FDA’s  satisfaction  that  our  products  are  safe  and  effective  for  their

intended uses;

·

·

the data from our pre-clinical studies and clinical trials may be insufficient to support clearance or approval, where
required; and

the manufacturing process or facilities we use may not meet applicable requirements.

In  addition,  the  FDA  may  change  its  clearance  and  approval  policies,  adopt  additional  regulations  or  revise  existing
regulations, or take other actions that may prevent or delay approval or clearance of our products under development or impact
our ability  to modify  our currently  approved  or cleared  products  on a timely  basis.  Any change  in the  laws or regulations  that
govern the clearance and approval processes relating to our current and future products could make it more difficult and costly to
obtain clearance or approval for new products, or to produce, market and distribute existing products.

36

 
Table of Contents

The FDA could also reclassify some or all of our products that are currently classified as Class II to Class III requiring
additional controls, clinical studies and submission of a PMA for us to continue marketing and selling those products. We cannot
guarantee  that the FDA will not reclassify  any of our Class II devices into Class III and require  us to submit a PMA for FDA
review and approval of the safety and effectiveness of our product. Any delay in, or failure to receive or maintain, clearance or
approval  for  our  products  under  development  could  prevent  us  from  generating  sales  from  these  products  or  achieving
profitability. Additionally, the FDA and other regulatory authorities have broad enforcement powers.  Regulatory enforcement or
inquiries,  or  other  increased  scrutiny  on  us,  could  dissuade  some  surgeons  from  using  our  products  and  adversely  affect  our
reputation and the perceived safety and efficacy of our products.

In addition, even after we have obtained the proper regulatory clearance or approval to market a product, the FDA has
the power to require us to conduct post marketing studies.  For example, we are required to continue to study and report clinical
results to the FDA on our silicone gel breast implants.  Failure to conduct this or other required studies in a timely manner could
result in the revocation of the PMA approval or 510(k) clearance for the product that is subject to such a requirement and could
also  result  in  the  recall  or  withdrawal  of  the  product,  which  would  prevent  us  from  generating  sales  from  that  product  in  the
United States.

Failure  to  comply  with  applicable  laws  and  regulations  could  jeopardize  our  ability  to  sell  our  products  and  result  in

enforcement actions such as:

· warning letters;

·

·

·

·

·

·

·

·

fines;

injunctions;

civil penalties;

termination of distribution;

recalls or seizures of products;

delays in the introduction of products into the market;

total or partial suspension of production;

refusal of the FDA or other regulator to grant future clearances or approvals;

· withdrawals  or  suspensions  of  current  clearances  or  approvals,  resulting  in  prohibitions  on  sales  of  our  products;

and/or

·

in the most serious cases, criminal penalties.

Any of these sanctions could result in higher than anticipated costs or lower than anticipated sales and have a material

adverse effect on our reputation, business, results of operations and financial condition.

If
we
or
our
third-party
manufacturer
fail
to
comply
with
the
FDA’s
good
manufacturing
practice
regulations,
it
could
impair
our
ability
to
market
our
products
in
a
cost-effective
and
timely
manner.

We and our third-party manufacturer are required to comply with the FDA’s Quality System Regulation, or QSR, which
covers  the  methods  and  documentation  of  the  design,  testing,  production,  control,  quality  assurance,  labeling,  packaging,
sterilization, storage and shipping of our products.  The FDA audits compliance with the QSR through periodic announced and
unannounced inspections of manufacturing and other facilities.  The FDA may conduct inspections or audits at any time.  If we or
our  manufacturer  fail  to  adhere  to  QSR  requirements,  have  significant  non-compliance  issues  or  fail  to  timely  and  adequately
respond to any adverse inspectional observations or product safety issues, or if any

37

 
Table of Contents

corrective action plan that we or our manufacturer propose in response to observed deficiencies is not sufficient, the FDA could
take enforcement action against us, which could delay production of our products and may include:

·

·

·

·

·

untitled letters, warning letters, fines, injunctions, consent decrees and civil penalties;

unanticipated expenditures to address or defend such actions;

customer notifications or repair, replacement, refunds, recall, detention or seizure of our products;

operating restrictions or partial suspension or total shutdown of production;

refusing or delaying our requests for 510(k) clearance or premarket approval of new products or modified products;

· withdrawing 510(k) clearances or pre-market approvals that have already been granted;

·

·

refusal to grant export approval for our products; or

criminal prosecution.

Any of the foregoing actions could have a material adverse effect on our reputation, business, financial condition and
operating  results.    Furthermore,  our  manufacturer  may  not  currently  be  or  may  not  continue  to  be  in  compliance  with  all
applicable regulatory requirements, which could result in our failure to produce our products on a timely basis and in the required
quantities, if at all.

There
is
no
guarantee
that
the
FDA
will
grant
510(k)
clearance
or
PMA
approval
of
our
future
products,
and
failure
to
obtain
necessary
clearances
or
approvals
for
our
future
products
would
adversely
affect
our
ability
to
grow
our
business.

Some of our future products may require FDA clearance of a 510(k) or FDA approval of a PMA.  The FDA may not
approve or clear these products for the indications that are necessary or desirable for successful commercialization.  Indeed, the
FDA may refuse our requests for 510(k) clearance or pre-market approval of new products.

Significant delays in receiving clearance or approval, or the failure to receive clearance or approval for our new products

would have an adverse effect on our ability to expand our business.

If 
we 
modify 
our 
FDA 
approved 
or 
cleared 
devices, 
we 
may 
need 
to 
seek 
additional 
clearances 
or 
approvals, 
which, 
if 
not
granted,
would
prevent
us
from
selling
our
modified
products.

In the United States, our silicone gel breast implants are marketed pursuant to a PMA order issued by the FDA in March
2012,  and  our  tissue  expanders  are  marketed  pursuant  to  pre-market  clearance  under  Section  510(k)  of  the  FDCA.    Any
modifications  to  a  PMA-approved  or  510(k)-cleared  device  that  could  significantly  affect  its  safety  or  effectiveness,  including
significant design and manufacturing changes, or that would constitute a major change in its intended use, manufacture, design,
components,  or  technology  requires  a  new  510(k)  clearance  or,  possibly,  approval  of  a  new  PMA  application  or  PMA
supplement.    However,  certain  changes  to  a  PMA-approved  device  do  not  require  submission  and  approval  of  a  new  PMA  or
PMA  supplement  and  may  only  require  notice  to  FDA  in  a  PMA  30-Day  Notice,  Special  PMA  Supplement  –  Changes  Being
Effected or PMA Annual Report.  The FDA requires every manufacturer to make this determination in the first instance, but the
FDA may review any manufacturer’s decision.  The FDA may not agree with our decisions regarding whether new clearances or
approvals are necessary.  We have modified some of our 510(k) cleared products, and have determined based on our review of the
applicable FDA guidance that in certain instances the changes did not require new 510(k) clearances or PMA approvals.  If the
FDA disagrees with our determination and requires us to seek new 510(k) clearances or PMA approvals for modifications to our
previously cleared or approved products for which we have concluded that new clearances or approvals are unnecessary, we may
be required to cease marketing or to recall the modified product until we obtain clearance or approval, and we may be subject to
significant  regulatory  fines  or  penalties.    Furthermore,  our  products  could  be  subject  to  recall  if  the  FDA  determines,  for  any
reason, that our products are not safe or effective or that appropriate regulatory submissions were not made.  Delays in receipt or
failure to receive

38

 
Table of Contents

approvals,  the  loss  of  previously  received  approvals,  or  the  failure  to  comply  with  any  other  existing  or  future  regulatory
requirements, could reduce our sales, profitability and future growth prospects.

A
recall
of
our
products,
either
voluntarily
or
at
the
direction
of
the
FDA
or
another
governmental
authority,
or
the
discovery
of
serious
safety
issues
with
our
products
that
leads
to
corrective
actions,
could
have
a
significant
adverse
impact
on
us.

The  FDA  and  similar  foreign  governmental  authorities  have  the  authority  to  require  the  recall  of  commercialized
products in the event of material deficiencies or defects in design or manufacture of a product or in the event that a product poses
an unacceptable risk to health.  The FDA’s authority to require a recall must be based on an FDA finding that there is reasonable
probability  that  the  device  would  cause  serious  injury  or  death.    Manufacturers  may  also,  under  their  own  initiative,  recall  a
product  if  any  material  deficiency  in  a  device  is  found  or  withdraw  a  product  to  improve  device  performance  or  for  other
reasons.  The FDA requires that certain classifications of recalls be reported to the FDA within 10 working days after the recall is
initiated . A government-mandated or voluntary recall by us or one of our distributors could occur as a result of an unacceptable
risk  to  health,  component  failures,  malfunctions,  manufacturing  errors,  design  or  labeling  defects  or  other  deficiencies  and
issues.  Similar regulatory agencies in other countries have similar authority to recall devices because of material deficiencies or
defects  in  design  or  manufacture  that  could  endanger  health.    Any  recall  would  divert  management  attention  and  financial
resources and could cause the price of our stock to decline, expose us to product liability or other claims and harm our reputation
with customers.  Such events could impair our ability to produce our products in a cost-effective and timely manner in order to
meet our customers’ demands.  A recall involving our silicone gel breast implants could be particularly harmful to our business,
financial and operating results.  Companies are required to maintain certain records of recalls, even if they are not reportable to
the FDA or similar foreign governmental authorities.  We may initiate voluntary recalls involving our products in the future that
we determine do not require notification of the FDA or foreign governmental authorities.  If the FDA or foreign governmental
authorities  disagree  with  our  determinations,  they  could  require  us  to  report  those  actions  as  recalls.    A  future  recall
announcement  could  harm  our  reputation  with  customers  and  negatively  affect  our  sales.    In  addition,  the  FDA  or  a  foreign
governmental authority could take enforcement action for failing to report the recalls when they were conducted.

In addition, under the FDA’s medical device reporting regulations, we are required to report to the FDA any incident in
which our product may have caused or contributed to a death or serious injury or in which our product malfunctioned and, if the
malfunction were to recur, would likely cause or contribute to death or serious injury.  Repeated product malfunctions may result
in  a  voluntary  or  involuntary  product  recall.    We  are  also  required  to  follow  detailed  recordkeeping  requirements  for  all  firm-
initiated medical device corrections and removals, and to report such corrective and removal actions to FDA if they are carried
out  in  response  to  a  risk  to  health  and  have  not  otherwise  been  reported  under  the  medical  device  reporting
regulations.  Depending on the corrective action we take to redress a product’s deficiencies or defects, the FDA may require, or
we may decide, that we will need to obtain new approvals or clearances for the device before we may market or distribute the
corrected  device.    Seeking  such  approvals  or  clearances  may  delay  our  ability  to  replace  the  recalled  devices  in  a  timely
manner.    Moreover,  if  we  do  not  adequately  address  problems  associated  with  our  devices,  we  may  face  additional  regulatory
enforcement  action,  including  FDA  warning  letters,  product  seizure,  injunctions,  administrative  penalties,  or  civil  or  criminal
fines.  We may also be required to bear other costs or take other actions that may have a negative impact on our sales as well as
face significant adverse publicity or regulatory consequences, which could harm our business, including our ability to market our
products in the future.

Any  adverse  event  involving  our  products,  whether  in  the  United  States  or  abroad,  could  result  in  future  voluntary
corrective  actions,  such  as  recalls  or  customer  notifications,  or  agency  action,  such  as  inspection,  mandatory  recall  or  other
enforcement  action.  Any corrective  action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will
require the dedication of our time and capital, distract management from operating our business and may harm our reputation and
financial results.

If
the
third
parties
on
which
we
rely
to
conduct
our
clinical
trials
and
to
assist
us
with
pre-clinical
development
do
not
perform
as
contractually
required
or
expected,
we
may
not
be
able
to
obtain
regulatory
clearance
or
approval
for
or
commercialize
our
products.

We often must rely on third parties, such as contract research organizations, medical institutions, clinical investigators
and  contract  laboratories  to  conduct  our  clinical  trials  and  prepare  our  regulatory  submissions.    If  these  third  parties  do  not
successfully carry out their contractual duties or regulatory obligations or meet expected deadlines, if these third parties need to
be replaced, or if the quality or accuracy of the data they obtain is compromised due to the failure to

39

 
Table of Contents

adhere to our clinical protocols or regulatory requirements or for other reasons, our pre-clinical development activities or clinical
trials may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory clearance or approval for,
or successfully commercialize, our products on a timely basis, if at all, and our business, operating results and prospects may be
adversely  affected.  Furthermore, our third-party  clinical  trial investigators  may be delayed in conducting our clinical trials  for
reasons outside of their control.

We
may
be
subject
to
regulatory
or
enforcement
actions
if
we
engage
in
improper
marketing
or
promotion
of
our
products.

Our  educational  and  promotional  activities  and  training  methods  must  comply  with  FDA  and  other  applicable  laws,
including the prohibition of the promotion of a medical device for a use that has not been cleared or approved by the FDA.  Use
of a device outside of its cleared or approved indications is known as “off-label” use.  Physicians may use our products off-label
in  their  professional  medical  judgment,  as  the  FDA  does  not  restrict  or  regulate  a  physician’s  choice  of  treatment  within  the
practice  of  medicine.    However,  if  the  FDA  determines  that  our  educational  and  promotional  activities  or  training  constitutes
promotion of an off-label use, it could request that we modify our training or promotional materials or subject us to regulatory or
enforcement  actions,  including  the  issuance  of  warning  letters,  untitled  letters,  fines,  penalties,  injunctions,  or  seizures,  which
could  have  an  adverse  impact  on  our  reputation  and  financial  results.    It  is  also  possible  that  other  federal,  state  or  foreign
enforcement  authorities  might  take  action  if  they  consider  our  educational  and  promotional  activities  or  training  methods  to
constitute promotion of an off-label use, which could result in significant fines or penalties under other statutory authorities, such
as laws prohibiting false claims for reimbursement.  In that event, our reputation could be damaged and adoption of the products
could  be  impaired.    Although  our  policy  is  to  refrain  from  statements  that  could  be  considered  off-label  promotion  of  our
products, the FDA or another regulatory agency could disagree and conclude that we have engaged in off-label promotion.  It is
also possible that other federal, state or foreign enforcement authorities might take action if they consider our business activities
constitute promotion of an off-label use, which could result in significant penalties, including, but not limited to, criminal, civil
and/or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs,
and  the  curtailment  or  restructuring  of  our  operations.    In  addition,  the  off-label  use  of  our  products  may  increase  the  risk  of
product liability claims.  Product liability claims are expensive to defend and could divert our management’s attention, result in
substantial damage awards against us, and harm our reputation.

Changes
in
existing
third-party
coverage
and
reimbursement
may
impact
our
ability
to
sell
our
products
when
used
in
breast
reconstruction
procedures.

Maintaining and growing sales of our products when used in breast reconstruction procedures depends, in part, on the
availability of coverage and adequate reimbursement from third-party payors, including government programs such as Medicare
and Medicaid, private insurance plans and managed care programs. Breast augmentation procedures are generally performed on a
cash ‑pay basis and are not covered by third ‑party payors. In contrast, breast reconstruction procedures may be covered by third
‑party  payors.  Therefore,  h  ospitals  and  other  healthcare  provider  customers  that  purchase  our  products  to  use  in  breast
reconstruction procedures typically bill various third-party payors to cover all or a portion of the costs and fees associated with
the procedures in which our products are used, including the cost of the purchase of our products. Decreases in the amount third-
party payors are willing to reimburse our customers for breast reconstruction procedures using our products could create pricing
pressures for us.  T he process for determining whether a third-party payor will provide coverage for a product or procedure may
be separate from the process for establishing the reimbursement rate that such a payor will pay for the product or procedure . A
payor’s  decision  to  provide  coverage  for  a  product  or  procedure  does  not  imply  that  an  adequate  reimbursement  rate  will  be
approved. Further, one payor’s determination to provide coverage for a product or procedure does not assure that other payors
will also provide such coverage. Adequate third-party reimbursement may not be available to enable us to maintain our business
in a profitable way .   We may be unable to sell our products on a profitable basis if third-party payors deny coverage or reduce
their current levels of payment, or if our costs of production increase faster than increases in reimbursement levels.

Furthermore,  the  healthcare  industry  in  the  United  States  has  experienced  a  trend  toward  cost  containment  as
government  and  private  insurers  seek  to  control  healthcare  costs  by  imposing  lower  payment  rates  and  negotiating  reduced
contract rates with service providers.  Therefore, we cannot be certain that the breast reconstruction procedures using our products
will be reimbursed at a cost-effective level.  Nor can we be certain that third-party payors using a methodology that sets amounts
based on the type of procedure performed, such as those utilized by government programs and in many privately managed care
systems, will view the cost of our products to be justified so as to incorporate such costs into the

40

 
Table of Contents

overall  cost  of  the  procedure.    Moreover,  we  are  unable  to  predict  what  changes  will  be  made  to  the  reimbursement
methodologies used by third-party payors in the future.

To  the  extent  we  sell  our  products  internationally,  market  acceptance  may  depend,  in  part,  upon  the  availability  of
coverage and reimbursement within prevailing healthcare payment systems.  Reimbursement and healthcare payment systems in
international  markets  vary  significantly  by  country,
 and  include  both  government-sponsored  healthcare  and  private
insurance.  We may not obtain international coverage and reimbursement approvals in a timely manner, if at all.  Our failure to
receive such approvals would negatively impact market acceptance of our products in the international markets in which those
approvals are sought.

Legislative 
or
regulatory
health


care
reforms 
may
make 
it
more
difficult 
and
costly 
to
produce, 
market 
and
distribute 
our
products
after
clearance
or
approval
is
obtained,
or
to
do
so
profitably.

Recent  political,  economic  and  regulatory  influences  are  subjecting  the  health  care  industry  to  fundamental  changes.
Both the federal and state governments in the United States and foreign governments continue to propose and pass new legislation
and regulations designed to contain or reduce the cost of health care, improve quality of care, and expand access to healthcare,
among other purposes.   Such legislation and regulations may result in decreased reimbursement for medical devices and/or the
procedures in which they are used, which may further exacerbate industry-wide pressure to reduce the prices charged for medical
devices.  This could harm our ability to market and generate sales from our products.

In addition, FDA regulations and guidance are often revised or reinterpreted by the FDA in ways that may significantly
affect our business and our products.  Any new regulations or revisions or reinterpretations of existing regulations may impose
additional costs or lengthen review times of our products.

Federal and state governments in the United States have recently enacted legislation to overhaul the nation’s health care
system.    For  example,  in  March  2010,  the  PPACA  was  signed  into  law.    While  one  goal  of  health  care  reform  is  to  expand
coverage  to  more  individuals,  it  also  involves  increased  government  price  controls,  additional  regulatory  mandates  and  other
measures  designed  to  constrain  medical  costs.    The  PPACA  substantially  changes  the  way  healthcare  is  financed  by  both
governmental  and  private  insurers,  encourages  improvements  in  the  quality  of  healthcare  items  and  services  and  significantly
impacts the medical device industry.  Among other ways in which the PPACA significantly impacts our industry, the PPACA:

·

·

·

·

·

imposes an annual excise tax of 2.3% on any entity that manufactures or imports medical devices offered for sale in
the United States, with limited exceptions;

expands eligibility criteria for Medicaid programs;

establishes  a  new  Patient-Centered  Outcomes  Research  Institute  to  oversee  and  identify  priorities  in  comparative
clinical effectiveness research in an effort to coordinate and develop such research;

implements  payment  system  reforms  including  a  national  pilot  program  on  payment  bundling  to  encourage
hospitals, physicians and other providers to improve the coordination, quality and efficiency of certain health care
services through bundled payment models; and

creates an independent payment advisory board that will submit recommendations to Congress to reduce Medicare
spending if projected Medicare spending exceeds a specified growth rate.

The  medical  device  excise  tax  has  been  suspended  by  the  CAA, with  respect  to  medical  device  sales  during  calendar
years 2016 and 2017.  Absent further Congressional action, this excise tax will be reinstated for medical device sales beginning
January 1, 2018.  The CAA also temporarily delays implementation of other taxes intended to help fund PPACA programs. We
are unsure of the full impact that the PPACA will have on our business.  There have been judicial and Congressional challenges to
certain aspects of the PPACA, and we expect there will be additional challenges and amendments in the future.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted.  For example, on

August 2, 2011, the President signed into law the Budget Control Act of 2011, which, among other things,

41

 
Table of Contents

created the Joint Select Committee on Deficit Reduction to recommend to Congress proposals in spending reductions.  The Joint
Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering
the  legislation’s  automatic  reduction  to  several  government  programs.    This  includes  reductions  to  Medicare  payments  to
providers of 2% per fiscal year, which went into effect on April 1, 2013 , following passage of the Bipartisan Budget Act of 2015,
and will stay in effect through 202 5 unless additional Congressional action is taken.  Additionally, on January 2, 2013, President
Obama  signed  into  law  the  A  TRA,  which,  among  other  things,  reduced  Medicare  payments  to  several  providers,  including
hospitals,  imaging  centers  and  cancer  treatment  centers  and  increased  the  statute  of  limitations  period  for  the  government  to
recover overpayments to providers from three to five years.

In the future there may continue to be additional proposals relating to the reform of the U.S. healthcare system.  Certain
of these proposals could limit the prices we are able to charge for our products, or the amount of reimbursement available for our
products, and could limit the acceptance and availability of our products, any of which could have a material adverse effect on our
business, results of operations and financial condition.

If
we
fail
to
obtain
and
maintain
regulatory
approval
in
Canada,
our
market
opportunities
will
be
limited.

In order to market our products in Canada, we must obtain and maintain separate regulatory approvals and comply with
numerous  and  varying  regulatory  requirements.    We  are  currently  not  able  to  obtain  Health  Canada’s  approval  to  market  our
breast implant products in Canada due to the suspension of Silimed’s ISO 13485 certificate.  Even if Silimed’s ISO certification is
reinstated, the time required to obtain regulatory  approval in Canada may be longer than the time required to obtain FDA pre-
market  approval  and  Health  Canada  may  want  additional  information  prior  to  approval  as  well  .    The  Canadian  regulatory
approval process includes many of the risks associated with obtaining FDA approval and we may not obtain Canadian regulatory
approval on a timely basis, if at all.  FDA approval does not ensure approval by regulatory authorities in other countries, including
Canada,  and  approval  by  one  foreign  regulatory  authority  does  not  ensure  approval  by  regulatory  authorities  in  other  foreign
countries.  However, the failure to obtain clearance or approval in one jurisdiction may have a negative impact on our ability to
obtain clearance or approval elsewhere.  If we do not obtain or maintain necessary approvals to commercialize our products in
Canada, it would negatively affect our overall market penetration.

Our 
customers 
and 
much 
of 
our 
industry 
are 
required 
to 
be 
compliant 
under 
the 
federal 
Health 
Insurance 
Portability 
and
Accountability 
Act 
of 
1996, 
the 
Health 
Information 
Technology 
for 
Economic 
and 
Clinical 
Health 
Act 
and 
implementing
regulations 
(including 
the 
final 
Omnibus 
Rule 
published 
on 
January 
25, 
2013) 
affecting 
the 
transmission, 
security 
and
privacy
of
health
information,
and
failure
to
comply
could
result
in
significant
penalties.

Numerous  federal  and  state  laws  and  regulations,  including  HIPAA,  and  the  Health  Information  Technology  for
Economic and Clinical Health Act, or the HITECH Act, govern the collection, dissemination, security, use and confidentiality of
health information that identifies specific patients.  HIPAA and the HITECH Act require our surgeon and hospital customers to
comply with certain standards for the use and disclosure of health information within their companies and with third parties.  The
Privacy Standards and Security Standards under HIPAA establish a set of standards for the protection of individually identifiable
health information by health plans, health care clearinghouses and certain health care providers, referred to as Covered Entities,
and  the  Business  Associates  with  whom  Covered  Entities  enter  into  service  relationships  pursuant  to  which  individually
identifiable  health  information  may be exchanged.  Notably, whereas  HIPAA previously  directly  regulated  only these  Covered
Entities,  the  HITECH  Act,  which  was  signed  into  law  as  part  of  the  stimulus  package  in  February  2009,  makes  certain  of
HIPAA’s  privacy  and  security  standards  also  directly  applicable  to  Covered  Entities’  Business  Associates.    As  a  result,  both
Covered Entities and Business Associates are now subject to significant civil and criminal penalties  for failure to comply with
Privacy Standards and Security Standards.

HIPAA  requires  Covered  Entities  (like  our  customers)  and  Business  Associates  to  develop  and  maintain  policies  and
procedures  with  respect  to  protected  health  information  that  is  used  or  disclosed,  including  the  adoption  of  administrative,
physical  and  technical  safeguards  to  protect  such  information.    The  HITECH  Act  expands  the  notification  requirement  for
breaches of patient-identifiable health information, restricts certain disclosures and sales of patient-identifiable health information
and provides for civil monetary penalties for HIPAA violations.  The HITECH Act also increased the civil and criminal penalties
that may be imposed against Covered Entities and Business Associates and gave state attorneys general new authority to file civil
actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney fees and costs associated
with  pursuing  federal  civil  actions.    Additionally,  certain  states  have  adopted  comparable  privacy  and  security  laws  and
regulations, some of which may be more stringent than HIPAA.

42

 
Table of Contents

We  are  not  currently  required  to  comply  with  HIPAA  or  HITECH  because  we  are  neither  a  Covered  Entity  nor  a
Business Associate (as that term is defined by HIPAA).  However, in administering our warranties and complying with FDA -
required device tracking, we do regularly handle confidential and personal information similar to that which these laws seek to
protect.  We also occasionally encounter hospital customers who pressure us to sign Business Associate Agreements, or BAAs,
although, to date, we have refused, given that we do not believe we are business associates to such Covered Entities under HIPAA
or  HITECH.    If  the  law  or  regulations  were  to  change  or  if  we  were  to  agree  to  sign  a  BAA, the  costs  of  complying  with  the
HIPAA standards are burdensome and could have a material adverse effect on our business.  In addition, under such situations
there would be significant risks and financial penalties for us if we were then found to have violated the laws and regulations that
pertain to Covered Entities and Business Associates.

We are unable to predict what changes to the HIPAA Privacy Standards and Security Standards might be made in the
future or how those changes could affect our business.  Any new legislation or regulation in the area of privacy and security of
personal  information,  including  personal  health  information,  could  also  adversely  affect  our  business  operations.    If  we  do  not
comply with existing or new applicable federal or state laws and regulations related to patient health information, we could be
subject to criminal or civil sanctions and any resulting liability could adversely affect our financial condition.

An 
adverse 
outcome 
of 
a 
sales 
and 
use 
tax 
audit 
could 
have 
a 
material 
adverse 
effect 
on 
our 
results 
of 
operations 
and
financial
condition.

We  sell  our  products  in  all  50  states  and  each  state  (and  some  local  governments)  has  its  own  sales  tax  laws  and
regulations.    We  charge  each  of  our  customers  sales  tax  on  each  order  and  report  and  pay  that  tax  to  the  appropriate  state
authority, unless we believe there is an applicable exception.  In some states, there are no available exceptions; in some states, we
believe our products can be sold tax free.  In other states, we believe we can sell our products tax free only for customers who
request tax-exempt treatment due to the nature of the devices we sell or due to the nature of the customer’s use of our device.  We
may  be  audited  by  the  taxing  authorities  of  one  or  more  states  and  there  can  be  no  assurance,  however,  that  an  audit  will  be
resolved in our favor.  Such an audit could be expensive and time-consuming and result in substantial management distraction.  If
the matter were to be resolved in a manner adverse to us, it could have a material adverse effect on our results of operations and
financial condition.

Risks Related to Our Common Stock

Our
stock
price
may
be
volatile,
and
you
may
not
be
able
to
resell
shares
of
our
common
stock
at
or
above
the
price
you
paid.

The  market  price  of  our  common  stock  is  likely  to  be  highly  volatile  and  could  be  subject  to  wide  fluctuations  in
response to various factors, some of which are beyond our control.  For example, our common stock price declined from $20.58
to  $2.78  from  September  23,  2015  to  November  17,  2015  as  a  result  of  the  recent  events  concerning  Silimed.  These factors
include those discussed in this “Risk Factors” section of this Form 10- K and others such as:

·

·

·

·

·

·

·

a determination that our Silimed-manufactured products are not in compliance with regulatory requirements, or its
facilities are not maintained in compliance with regulatory requirements;

a slowdown in the medical device industry, the aesthetics industry or the general economy;

actual or anticipated quarterly or annual variations in our results of operations or those of our competitors;

changes in accounting principles or changes in interpretations of existing principles, which could affect our financial
results;

actual or anticipated changes in our growth rate relative to our competitors;

changes in earnings estimates or recommendations by securities analysts;

fluctuations in the values of companies perceived by investors to be comparable to us;

43

announcements  by  us  or  our  competitors  of  new  products  or  services,  significant  contracts,  commercial
relationships, capital commitments or acquisitions;

competition from existing technologies and products or new technologies and products that may emerge;

the entry into, modification or termination of agreements with our sales representatives or distributors;

developments with respect to intellectual property rights;

sales, or the anticipation of sales, of our common stock by us, our insiders or our other stockholders, including upon
the expiration of contractual lock-up agreements;

our ability to develop and market new and enhanced products on a timely basis;

our commencement of, or involvement in, litigation;

additions or departures of key management or technical personnel; and

changes in laws or governmental regulations applicable to us.

In  recent  years,  the  stock  markets  generally  have  experienced  extreme  price  and  volume  fluctuations  that  have  often
been  unrelated  or  disproportionate  to  the  operating  performance  of  those  companies.    Broad  market  and  industry  factors  may
significantly affect the market price of our common stock, regardless of our actual operating performance.

We 
and 
certain 
of 
our 
executive 
officers 
and 
directors 
have 
been 
named 
as 
defendants 
in 
recently 
initiated 
securities 
class
action
lawsuit
that
could
result
in
substantial
costs
and
divert
management’s
attention.

On  September  25,  2015,  a  lawsuit  styled  as  a  class  action  of  our stockholders  was  filed  in  the  United  States  District
Court for the Central District of California. The lawsuit names us and certain of our officers as defendants and alleges violations
of  Sections  10(b)  and  20(a)  of  the  Exchange  Act  in  connection  with  allegedly  false  and  misleading  statements  concerning  our
business,  operations,  and  prospects.    On  October  28,      November  5,  and  November  19,  2015, three     lawsuits  styled  as  class
actions of our stockholders were filed in the Superior Court of California for the County of San Mateo. The lawsuits name us ,
certain of our officers and directors, and the underwriters associated with our follow-on public offering that closed on September
23, 2015 as defendants and alleges violations of Sections 11, 12(a)(2), and 15 of the Securities Act in connection with allegedly
false  and  misleading  statements  in  our  offering  documents  associated  with  the  follow-on  offering  concerning  our  business,
operations, and prospects. We intend to engage in a vigorous defense of such litigation. If we are not successful in our defense of
such litigation, we could be forced to make significant payments to or other settlements with our stockholders and their lawyers,
and such payments or settlement arrangements could have a material adverse effect on our business, operating results or financial
condition. Even if these claims are not successful, the litigation could result in substantial costs and significant adverse impact on
our  reputation  and  divert  management’s  attention  and  resources,  which  could  have  a  material  adverse  effect  on  our  business,
operating results or financial condition.

We
do
not
anticipate 
paying
any
cash
dividends 
in
the
foreseeable 
future,
and
accordingly,
stockholders 
must
rely 
on
stock
appreciation
for
any
return
on
their
investment.

We do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future.  As a result,

capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

Our
executive
officers,
directors
and

own
a
significant
percentage
of
our
stock
and
will
be
able
to
exert
significant
control
over
matters
subject
to
stockholder
approval.

As  of  March  7,  2016,  our  executive  officers,  directors  and  principal  stockholders  beneficially  owned  approximately
50.7% of our outstanding voting stock. As a result, these stockholders have the ability to influence us through their ownership
position and may be able to determine all matters requiring stockholder approval.  For example, these stockholders may be able to
control elections of directors, amendments of our organizational documents, or approval

44

of  any  merger,  sale  of  assets,  or  other  major  corporate  transaction.    This  may  prevent  or  discourage  unsolicited  acquisition
proposals or offers for our common stock that you may feel are in your best interest as one of our stockholders.

We 
are 
an 
“emerging 
growth 
company” 
and 
intend 
to 
take 
advantage 
of 
reduced 
disclosure 
requirements 
applicable 
to
emerging
growth
companies,
which
could
make
our
common
stock
less
attractive
to
investors.

We  are  an  “emerging  growth  company,”  as  defined  in  the  JOBS  Act,  and  we  intend  to  take  advantage  of  certain
exemptions from various reporting requirements that apply to other public companies that are not “emerging growth companies.”
As an emerging growth company:

· we are exempt from the requirement to obtain an attestation and report from our auditors on the assessment of our
internal control over financial reporting pursuant to the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act;

· we  are  permitted  to  provide  less  extensive  disclosure  about  our  executive  compensation  arrangements  in  our

periodic reports, proxy statements and registration statements; and

· we  are  not  required  to  give  our  stockholders  non-binding  advisory  votes  on  executive  compensation  or  golden

parachute arrangements.

In  addition,  the  JOBS  Act  provides  that  an  emerging  growth  company  may  take  advantage  of  an  extended  transition
period  for  complying  with  new  or  revised  accounting  standards.    We  have  irrevocably  elected  not  to  avail  ourselves  of  this
exemption and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are
not emerging growth companies.

We may remain an emerging growth company until December 31, 2019 (the last day of the fiscal year following the fifth
anniversary of our initial public offering).  However, if certain events occur prior to the end of such five-year period, including if
we become a “large accelerated filer,” our annual gross revenue equals or exceeds $1.0 billion or we issue more than $1.0 billion
of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-
year period.

We 
have 
incurred 
increased 
costs 
as 
a 
result 
of 
operating 
as 
a 
public 
company 
and 
our 
management 
is 
required 
to 
devote
substantial
time
to
new
compliance
initiatives
and
corporate
governance
practices.

As a public company, and increasingly after we are no longer an “emerging growth company,” we will incur significant
legal, accounting and other expenses that we did not incur as a private company.  In addition, the Sarbanes-Oxley Act and rules
subsequently  implemented  by  the  SEC  and  NASDAQ  impose  numerous  requirements  on  public  companies,  including
establishment  and  maintenance  of  effective  disclosure  and  financial  controls  and  corporate  governance  practices.    Also,  the
Exchange  Act  requires,  among  other  things,  that  we file  annual,  quarterly  and  current  reports  with  respect  to  our  business  and
operating results.  Our management and other personnel will need to devote a substantial amount of time to compliance with these
laws  and  regulations.    These  requirements  have  increased  and  will  continue  to  increase  our  legal,  accounting  and  financial
compliance costs and have made and will continue to make some activities more time consuming and costly.  For example, we
expect  these  rules  and  regulations  to  make  it  more  difficult  and  more  expensive  for  us  to  obtain  director  and  officer  liability
insurance,  and  we  may  be  required  to  incur  substantial  costs  to  maintain  the  same  or  similar  coverage.    These  rules  and
regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors or our
board committees or as executive officers.

Overall, our incremental costs resulting from operating as a public company, including compliance with these rules and
regulations, was approximately $3.2 million for the year ended December 31, 2015 .  However, these rules and regulations are
often 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.

As 
a 
public 
company, 
we 
are 
required 
to 
assess 
our 
internal 
control 
over 
financial 
reporting 
on 
an 
annual 
basis, 
and 
any
future
adverse
results
from
such
assessment
could
result
in
a
loss
of
investor
confidence
in
our
financial
reports
and
have
an
adverse
effect
on
our
stock
price.

As a public company, we are required to comply with certain of the requirements of Section 404 of the Sarbanes-Oxley
Act of 2002, as amended, regarding internal control over financial reporting. However, for as long as we remain an “emerging
growth  company”  as  defined  in  the  JOBS  Act,  we  intend  to  utilize  the  provision  exempting  us  from  the  requirement  that  our
independent  registered  public  accounting  firm  provide  an  attestation  on  the  effectiveness  of  our  internal  control  over  financial
reporting

Prior  to  becoming  a  public  company,  we  were  not  required  to  comply  with  the  requirements  of  Section  404  but
previously  we  had  identified  two  material  weaknesses  in  our  internal  control  over  financial  reporting  for  certain  financial
statement  periods  included  in  this  report.  A  “material  weakness”  is  a  deficiency,  or  a  combination  of  deficiencies,  in  internal
control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim
financial  statements  will  not  be  prevented  or  detected  on  a  timely  basis.  The  identified  material  weaknesses  related  to  our  not
having  properly  designed  controls  in  place  to  account  for  complex  debt  and  equity  transactions,  including  preferred  stock  and
warrants  associated  with  debt  issuances,  and  to  record  bonus  accrual  and  related  expense  in  the  appropriate  period.  While  we
believe we have remediated these previously reported material weaknesses, we cannot assure you that we will not be required to
take further remedial action with respect to those material weaknesses or that there will not be material weaknesses or significant
deficiencies in our internal controls in the future.

The  process  of  becoming  fully  compliant  with  Section  404  may  divert  internal  resources  and  will  take  a  significant
amount of time and effort to complete, and may result in additional deficiencies and material weaknesses being identified by us or
our  independent  registered  public  accounting  firm.  We  may  experience  higher  than  anticipated  operating  expenses,  as  well  as
increased independent registered public accounting firm fees during the implementation of any required changes and thereafter.
Completing  documentation  of  our  internal  control  system  and  financial  processes,  remediation  of  control  deficiencies  and
management testing of internal controls will require substantial effort by us. If our internal control over financial reporting or our
related disclosure controls and procedures are not effective, we may not be able to accurately report our financial results or file
our periodic reports in a timely manner, which may cause investors to lose confidence in our reported financial information and
may lead to a decline in our stock price.

Sales
of
a
substantial
number
of
shares
of
our
common
stock
in
the
public
market
could
cause
our
stock
price
to
decline.

Sales of a substantial number of shares of our common stock in the public market could occur at any time.  These sales,
or the perception in the market that our officers, directors or the holders of a large number of shares of common stock intend to
sell shares, could reduce the market price of our common stock.  As of March 7, 2016, we had approximately 18,066,345 shares
of common stock outstanding. Of these shares, all of the shares of our common stock sold in our initial public offering, which was
completed on November 3, 2014, and all of the shares sold in our follow-on public offering, which was completed on September
23, 2015 are freely tradable, without restriction, in the public market.

Each  of  our  directors  and  officers  and  substantially  all  of  our  stockholders,  optionholders  and  warrantholders  entered
into lock-up agreements  with the underwriters in connection with our initial  public offering  and our follow-on public offering.
The  lock-up  agreements  for  the  IPO  expired  on  April  27,  2015,  and  the  lock-up  agreements  for  the  follow-on  public  offering
expired  on December  23, 2015.  Based on shares  outstanding  as  of March  7, 2016, and information  contained  in Form 4s and
Schedule 13Gs filed with the SEC, up to an additional 4,947,083 shares of common stock became eligible for sale in the public
market, approximately 17,306 of which are held by our executive officers and directors and approximately 4,929,777 of which are
held by our affiliates (including stockholders affiliated with our directors) and subject to volume limitations under Rule 144 under
the Securities Act.

Holders  of  an  aggregate  of  approximately  6,287,277  shares  of  our  common  stock  have  rights,  subject  to  some
conditions, to require us to file registration statements covering their shares or to include their shares in registration statements
that we may file for ourselves or other stockholders.

As  of  March  7, 2016  ,  options  to  purchase  an  aggregate  of  2,217,238  shares  of  our  common  stock  were  outstanding
under our 2007 Plan and our 2014 Plan, which have been registered on a Registration Statement on Form S-8, and an additional,
672,612 shares of common stock are reserved for issuance under our 2014 Plan are registered on the Registration Statement on
Form S-8. These shares can be freely sold in the public market upon issuance and once vested.

Table of Contents

In addition , on March 7, 2016, we adopted an Inducement Plan pursuant to which our board of directors may grant stock
options or restricted stock units which may be exercised or settled, as applicable, for up to an aggregate of 180,000 shares of our
common stock, to new employees as inducement material to such new employees entering into employment with us.  We intend
to register the 180,000 shares of common stock reserved pursuant to our Inducement Plan on a Registration Statement on Form S-
8 after which shares issued pursuant to options or restricted stock awards granted under the Inducement Plan may be freely sold in
the public market once vested.

We cannot predict what effect, if any, sales of our shares in the public market or the availability of shares for sale will
have on the market price of our common stock. Future sales of substantial amounts of our common stock in the public market,
including shares issued upon exercise of outstanding options or warrants, or the perception that such sales may occur, however,
could  adversely  affect  the  market  price  of our  common  stock  and  also could  adversely  affect  our  future  ability  to raise  capital
through the sale of our common stock or other equity-related securities of ours at times and prices we believe appropriate.

Future 
sales 
and 
issuances 
of 
our 
common 
stock 
or 
rights 
to 
purchase 
common 
stock
 , 
including 
pursuant 
to 
our 
equity
incentive
plans,
could
result
in
additional
dilution
of
the
percentage
ownership
of
our
stockholders
and
could
cause
our
stock
price
to
fall.

We expect that significant additional capital may be needed in the future to continue our planned operations, including
conducting  clinical  trials,  commercialization  efforts,  expanded  research  and  development  activities  and  costs  associated  with
operating a public company. To raise capital, we may sell common stock, convertible securities or other equity securities in one
or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or
other equity securities, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to
our existing stockholders, and new investors could gain rights, preferences and privileges senior to the holders of our common
stock.

Pursuant  to  the  2014  Plan,  our  management  is  authorized  to  grant  stock  options  to  our  employees,  directors  and

consultants.

As  of  December  31,  2015,  the  number  of  shares  of  common  stock  reserved  for  issuance  under  our  2014  plan  was
1,325,759 . The number of shares of our common stock reserved for issuance under the 2014 Plan automatically  increase  s on
January 1 of each year, beginning on January 1, 2015 and continuing through and including January 1, 2024, by 4% of the total
number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares
determined by our board of directors. Unless our board of directors elects not to increase the number of shares available for future
grant each year, our stockholders may experience additional dilution, which could cause our stock price to fall. Pursuant to the
foregoing provision, effective January 1, 2016, our board of directors increased the number of shares of common stock reserved
for issuance under the 2014  Plan  by  4%  of  the  number  of  shares  of  our  capital  stock  outstanding  on  December  31, 201  5 , or
719,736 shares.

Our board of directors adopted our ESPP in July 2014 and our stockholders approved the ESPP in October 2014. Our
ESPP is intended to qualify as an employee stock purchase plan under Section 423 of the Code. The ESPP became effective upon
the completion  of the  IPO. As of December  31, 2015, the  number  of shares  of common  stock reserved  for issuance  under our
ESPP was 404,629 .   The number of shares of our common stock reserved for issuance under the ESPP   a utomatically increase s
on January 1 of each year, beginning on January 1, 2015 and continuing through and includi ng January 1, 2024, by 1 % of the
total  number  of  shares  of  our  capital  stock  outstanding  on  December  31  of  the  preceding  calendar  year,  or  a  lesser  number  of
shares determined by our board of directors. Unless our board of directors elects not to increase the number of shares available for
future grant each year, our stockholders may experience additional dilution, which could cause our stock price to fall. Pursuant to
the  foregoing  provision,  effective  January  1,  2016,  our  board  of  directors  increased  the  number  of  shares  of  common  stock
reserved for issuance under the   ESPP by 1 % of the number of shares of our capital stock outstanding on December 31, 201 5 ,
or 179,934 shares.

Pursuant  to  our  Inducement  Plan,  our  board  of  directors  is  authorized  to  grant  stock  options  or  restricted  stock  units
which may be exercised or settled, as applicable, for up to an aggregate of 180,000 shares of our common stock to new employees
as inducements material to such new employees entering into employment with us. The number of shares which may be granted
under the Inducement Plan may be increased in the future by our board of directors.

Our
management
team
may
invest
or
spend
the
proceeds
from
our
IPO
and
our
follow-on
public
offering
in
ways
with
which
you
may
not
agree
or
in
ways
which
may
not
yield
a
return.

Our management has considerable discretion in the application of the net proceeds from our public offerings, and you
will not have the opportunity as part of your investment decision to assess whether the net proceeds are being used appropriately.
Because of the number and variability of factors that will determine our use of the net proceeds from our public offerings, their
ultimate use may vary substantially from their currently intended use. Our management might not apply our net proceeds in ways
that ultimately increase the value of your investment. We expect that we will use the net proceeds from our public offerings for
the  following  purposes:  (i)  we  may  acquire  or  invest  in  complementary  products,  technologies,  businesses  or  international
expansion opportunities; however, we currently have no agreements or commitments to complete any such transaction, and (ii)
for working capital and other general corporate purposes. We also used a portion of the net proceeds from our public offerings to
repay our long-term debt. The failure by our management to apply these funds effectively could harm our business. Pending their
use,  we  may  invest  the  net  proceeds  from  our  public  offerings  in  high-quality,  short-term  interest-  bearing  obligations,
investment-grade  instruments,  certificates  of  deposit  or  direct  or  guaranteed  obligations  of  the  U.S.  government.  These
investments may not yield a favorable return to our stockholders. If we do not invest or apply the net proceeds from our public
offerings in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock
price to decline.

Anti-takeover 
provisions 
in 
our 
organizational 
documents 
and 
under 
Delaware 
law 
may 
discourage 
or 
prevent 
a 
change 
of
control,
even
if
an
acquisition
would
be
beneficial
to
our
stockholders,
which
could
reduce
our
stock
price
and
prevent
our
stockholders
from
replacing
or
removing
our
current
management.

Our amended  and restated  certificate  of incorporation  and amended  and restated  bylaws contain  provisions that  could
delay or prevent a change of control of our company or changes in our board of directors that our stockholders might consider
favorable.  Some of these provisions include:

·

·

·

·

·

·

·

a board of directors divided into three classes serving staggered three-year terms, such that not all members of the
board will be elected at one time;

a prohibition on stockholder action through written consent, which requires that all stockholder actions be taken at a
meeting of our stockholders;

a  requirement  that  special  meetings  of  stockholders  be  called  only  by  the  chairman  of  the  board  of  directors,  the
chief executive officer, or by a majority of the total number of authorized directors;

advance notice requirements for stockholder proposals and nominations for election to our board of directors;

a requirement that no member of our board of directors may be removed from office by our stockholders except for
cause  and,  in  addition  to  any  other  vote  required  by  law,  upon  the  approval  of  not  less  than  two-thirds  of  all
outstanding shares of our voting stock then entitled to vote in the election of directors;

a  requirement  of  approval  of  not  less  than  two-thirds  of  all  outstanding  shares  of  our  voting  stock  to  amend  any
bylaws by stockholder action or to amend specific provisions of our certificate of incorporation; and

the authority of the board of directors to issue preferred stock on terms determined by the board of directors without
stockholder approval and which preferred stock may include rights superior to the rights of the holders of common
stock.

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware, which may
prohibit certain business combinations with stockholders owning 15% or more of our outstanding voting stock.  These and other
provisions in our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law could make it
more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed
by our then-current board of directors, including a merger, tender offer or proxy contest involving our Company.  Any delay or
prevention of a change of control transaction or changes in our board of directors could cause the market price of our common
stock to decline.

The  trading  market  for  our  common  stock  will  be  influenced  by  the  research  and  reports  that  industry  or  securities
analysts publish about us or our business.  If any of the analysts who cover us issue an adverse or misleading opinion regarding
us,  our  business  model,  our  intellectual  property  or  our  stock  performance,  or  if  our  clinical  trials  and  operating  results  fail  to
meet the expectations of analysts, our stock price would likely decline.  If one or more of these analysts cease coverage of us, or
fail to publish reports on us regularly, including the recent suspension of our rating by certain analysts as a result of recent events
involving Silimed, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to
decline.

Item 2.  Propertie s

Our headquarters located in Santa Barbara, California is approximately 20,000 square feet. The term of the lease for our
headquarters  expires  in  February  2020.  We  also  lease      warehouse  space  s  located  in  Santa  Barbara,  California,  which  is   
approximately  10,000      square  feet  .  The      lease  term  expir es in  January  201 9 .  We  believe  that  our  existing  facilities  are
adequate for our current needs. As additional space is needed in the future, we believe that suitable space will be available in the
required locations on commercially reasonable terms.

Item 3.  Legal Proceeding s

On September 25, 2015, a lawsuit styled as a class action of the Company’s   stockholders was filed in the United States
District Court for the Central District of California. The lawsuit names the Company   and certain of our   officers as defendants
and  alleges  violations  of  Sections  10(b)  and  20(a)  of  the  Exchange  Act  in  connection  with  allegedly  false  and  misleading
statements concerning our   business, operations, and prospects.  The plaintiff seeks damages and an award of reasonable costs
and expenses, including attorneys’ fees.   On November 24, 2015, three stockholders (or groups of stockholders) filed motions to
appoint  lead  plaint  i ff(s)  and  to  approve  their  selection  on  lead  counsel.    On  December  10,  2015,  the  court  entered  an  order
appointing  lead  plaintiffs  and  approving  their  selection  of  lead  counsel.    On  February  19,  2016,  lead  plaintiffs  filed  their
consolidated amended complaint. 

On  October  28,  November  5  ,  and  November  19  ,  2015,  three     lawsuits  styled  as class  actions  of  the  Company’s   
stockholders  were  filed  in  the  Superior  Court  of  California  for  the  County  of  San  Mateo.  The  lawsuits  name  the  Company  ,
certain  of  our      officers  and  directors,  and  the  underwriters  associated  with  our      follow-on  public  offering  that  closed  on
September  23,  2015  as  defendants.  The  lawsuits  allege  violations  of  Sections  11,  12(a)(2),  and  15  of  the  Securities  Act  in
connection  with  allegedly  false  and  misleading  statements  in  our     offering  documents  associated  with  the  follow-on  offering
concerning our   business , operations, and prospects. The plaintiffs seek damages and an award of reasonable costs and expenses,
including attorneys’ fees. On December 4, 2015, defendants removed all three lawsuits to the United States District Court for the
Northern District of California. On December 15 and December 16, 2015, plaintiffs filed motions to remand the lawsuits back to
San Mateo Superior Court , or the Motions to Remand.  On January 19, 2016, defendants filed their opposition to the Motions to
Remand, and plaintiffs filed their reply in support of the Motions to Remand on January 26, 2016.

It is possible that additional suits will be filed, or allegations made by stockholders, with respect to these same or other
matters and also naming the Company and/or our officers and directors as defendants. We believe we have meritorious defenses
and  intend  to  defend  these  lawsuits  vigorously.    Due  to  the  early  stage  of  these  proceedings,      we  are  not  able  to  predict  or
reasonably estimate the ultimate outcome or possible losses relating to these claims.

Stock Performance Graph

The graph set forth below compares the cumulative total stockholder return on our common stock between October 29,
2014 (the date of our initial public offering) and December 31, 2015, with the cumulative total return of (a) the NASDAQ Health
Care  Index  and  (b)  the  NASDAQ  Composite  Index,  over  the  same  period.  This  graph  assumes  the  investment  of  $100  on
October 29, 2014 in our common stock, the NASDAQ Health Care Index and the NASDAQ Composite Index and assumes the
reinvestment of dividends, if any. The graph assumes our closing sales price on October 29, 2014 of $16.75 per share as the initial
value of our common stock and not the initial offering price to the public of $15.00 per share.

The comparisons shown in the graph below are based upon historical data. We caution that the stock price performance
shown in the graph below is not necessarily indicative of, nor is it intended to forecast, the potential future performance of our
common stock. Information used in the graph was obtained from the Nasdaq Stock Market LLC, a financial data provider and a

Holders of Record

As  of  March  7, 2016  ,  there  were approximately  118 holders  of  record  of  our  common  stock.  The  actual  number  of

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.

Information about our equity compensation plans is incorporated herein by reference to Item 12 of Part III of this Annual

Report on Form 10 ‑K.

Use of Proceeds from Public Offering of Common Stock

On  November  3,  2014,  we  closed  the  sale  of  5,750,000  shares  of  common  stock  to  the  public  (inclusive  of  750,000
shares of common stock sold by us pursuant to the full exercise of an overallotment option granted to the underwriters) at a price
of $15.00 per share. The offer and sale of the shares in the IPO was registered under the Securities Act pursuant to registration
statements  on  Form  S  ‑1  (File  No.  333  ‑198837),  which  was  filed  with  the  SEC,  on  September  19,  2014  and  amended
subsequently  and  declared  effective  on  October  28,  2014.  Piper  Jaffray  &  Co.  and  Stifel,  Nicolaus  &  Company,  Incorporated
acted  as  managing  underwriters  of  the  offering.      We  raised  approximately  $77.0  million  in  net  proceeds  after  deducting
underwriting  discounts  and  commissions  of  approximately  $6.0  million  and  other  offering  expenses  of  approximately
$3.2 million. None of these expenses consisted of payments made by us to directors, officers or persons owning 10% or more of
our common stock or to their associates, or to our affiliates.

On September 23, 2015, we closed the sale of 3,000,000 shares of common stock in a f ollow-on public offering   at a
price of  $22.00  per  share.  The  offer  and  sale  of  the  shares  in  the  follow-on  offering  were  registered  under  the  Securities  Act
pursuant to registration statements on Form S-1 (File No. 333-206755), which was filed with the SEC and declared effective on
September 17, 2015. Piper Jaffray & Co. and Stifel, Nicolaus & Company, Incorporated acted as joint book-running managers
and Leerink Partners, LLC and William Blair & Company, LLC . acted as co-managers. We raised approximately $61.4 million
in  net  proceeds      after  deducting  underwriting  discounts  and  commissions  of  approximately  $4.0  million  and  other  offering
expenses  of  approximately  $0.6  million.  None  of  these  expenses  consisted  of  payments  made  by  us  to  directors,  officers  or
persons owning 10% or more of our common stock or to their associates, or to our affiliates.

Upon receipt, the net proceeds from our IPO and our follow-on public offering were held in cash and cash equivalents,
primarily  bank  money  market  accounts.  There  has  been  no  material  change  in  our  planned  use  of  the  net  proceeds  from  the
offering as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act on October 29,
2014, or from our follow-on public offering as described in our final prospectus filed with the SEC pursuant to Rule 424(b) under
the  Securities  Act  on  September  23,  2015.  The  amount  and  timing  of  our  actual  expenditures  depend  on  numerous  factors,
including  the  ongoing  status  of  and  results  from  clinical  trials,  as  well  as  any  unforeseen  cash  needs.  Accordingly,  our
management will have broad discretion in the application of the net proceeds.

There were no repurchases of shares of common stock made during the year ended December 31, 2015 .

Item 7.  Management’s Discussion and Analysi s of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction
with  our  financial  statements  and  related  notes  appearing  elsewhere  in  this  Annual  Report  on  Form  10  ‑K.     This discussion
contains forward ‑looking statements that reflect our plans, estimates and beliefs, and involve risks and uncertainties. Our actual
results and the timing of certain events could differ materially from those anticipated in these forward ‑looking statements as a
result  of  several  factors,  including  those  discussed  in  the  section  titled  “Risk  Factors”  included  under  Part  I,  Item  1A  and
elsewhere in this Annual Report. See “Special Note Regarding Forward ‑Looking Statements” in this Annual Report.

Overview

We  are  a  medical  aesthetics  company  committed  to  making  a  difference  in  patients’  lives  by  enhancing  their  body
image, growing their self ‑esteem and restoring their confidence. We were founded to provide greater choice to board ‑certified
plastic  surgeons  and  patients  in  need  of  medical  aesthetics  products.  We  have  developed  a  broad  portfolio  of  products  with
technologically differentiated characteristics, supported by independent laboratory testing and strong clinical trial outcomes.   We
sell  our  breast  implants  and  breast  tissue  expanders,  or  Breast  Products,  exclusively  to  board-certified  and  board-admissible
plastic surgeons and tailor our customer service offerings to their specific needs, which we believe helps secure their loyalty and
confidence.

Our  primary  products  are  silicone  gel  breast  implants  for  use  in  breast  augmentation  and  breast  reconstruction
procedures, which we offer in over 195 variations of shapes, sizes , fill volumes and textures. Our breast implants are primarily
used in elective procedures which are generally performed on a cash ‑pay basis. Many of our breast implants incorporate one or
more differentiated technologies, including a proprietary high ‑strength, cohesive silicone gel and proprietary texturing branded
TRUE Texture ® .   Our breast implants offer a desired balance between strength, shape retention and softness due to the high-
strength, cohesive silicone gel used in our manufacturing process. TRUE Texture ® provides texturing on the implant shell that is
designed to reduce the incidence of malposition, rotation and capsular contracture.     We also offer breast tissue expanders and a
range  of  other  aesthetic  and  specialty  products.  We  do  not  have  any  patents  or  patent  applications,  but  rely  on  trade  secrets,
proprietary know ‑how and regulatory barriers to protect our products and technologies.

Our  breast  implants  were  approved  by  the  U.S.  Food  and  Drug  Administration,  or  FDA,  in  2012,  based  on  data  we
collected from our ongoing, long ‑term clinical trial of our breast implants in 1,788 women across 36 investigational sites in the
United States , which included 3,506 implants (approximately 53% of which were smooth and 47% of which were textured).  Our
clinical trial is the largest prospective, long-term safety and effectiveness pivotal study of breast implants in the United States and
included the largest magnetic resonance imaging, or MRI, cohort with 571 patients. The MRI cohort is a subset of study patients
that underwent regular MRI screenings in addition to the other aspects of the clinical trial protocol prior to FDA approval. Post-
approval,  all  patients  in  the  Study  are  subject  to  serial  MRI  screening  as  part  of  the  clinical  protocol  .  The  clinical  data  we
collected  over  an  eight-year  follow-up  period  demonstrated  rupture  rates,  capsular  contracture  rates  and  reoperation  rates  that
were comparable to or better than those of our competitors, at similar time points. In addition to our pivotal study, our clinical
data is supported by our Continued Access Study of 2,497 women in the United States. We have also commissioned a number of
bench trials run by independent laboratories that we believe further demonstrate the advantages of our breast implants over those
of our competitors .

We  sell  our  Breast  Products  exclusively  to  board-certified  and  board-admissible  plastic  surgeons,  who  we  refer  to  as
Plastic  Surgeons.  We  seek  to  provide  Plastic  Surgeons  with  differentiated  services,  including  enhanced  customer  service
offerings,  a  ten-year  limited  warranty  that  is  the  best-in-the-industry  based  on  providing  patients  with  the  largest  cash
reimbursement  for  certain  out-of-pocket  costs  related  to  revision  surgeries  in  a  covered  event;  a  lifetime  no-charge  implant
replacement program for covered ruptures; and our industry-first CapCon Care Program, or C3 Program, through which we offer
no-charge replacement  implants to breast augmentation patients who experience capsular contracture within the first five years
after implantation with our smooth or textured breast implants .

We sell our products in the United States through a direct sales organization consisting of 51 employees, including 43

sales representatives and 8 sales managers, as of December 31, 2015 .

Silimed Related Developments

On September 23, 2015, MHRA, an executive agency of the U.K., issued a press release announcing the suspension of sales and
implanting  in  U.K  .  of  all  medical  devices  manufactured  by  Silimed  following  the  suspension  of  the  CE  certificate  of  these
products issued by TUV SUD, Silimed’s notified body under EU regulation. The suspension of Silimed’s CE certificate by TUV
SUD  followed  TUV  SUD’s  inspection  at  Silimed’s  manufacturing  facilities  in  Brazil,  relating  to  particles  on  Silimed  breast
products.

On October 2, 2015, the Brazilian regulatory agency ANVISA and the Department of the Secretary of State of the State of Rio de
Janeiro  announced  that  while  they  continue  to  review  the  technical  compliance  related  to  GMP  of  Silimed’s  manufacturing
facility, and as a precautionary measure, they temporarily suspended the manufacturing and shipment of all medical devices made
by Silimed, including products manufactured for Sientra. ANVISA reiterated that no risks to patient health have been identified in
connection  with  implanting  Silimed  products,  and,  accordingly,  there  is  no  need  to  adopt  any  procedure  or  action  for  those
patients who have received them. Furthermore, ANVISA also indicated that, based on their contact to date with foreign regulatory
authorities, there have been no reports of adverse events related to this issue.

On October 9, 2015, we voluntarily placed a hold on the sale of all Sientra devices manufactured by Silimed and recommended
that plastic surgeons discontinue implanting the devices until further notice. The Company had ongoing discussions with the FDA
regarding European and Brazilian regulatory inquiries into Silimed products, and conducted its own review of the matter with the
assistance of independent experts in quality management systems, GMP and data-based risk assessment. The FDA also reiterated
that no reports of adverse events and no risks to patient health had been identified in connection with this issue.

On October 22, 2015, there was a fire at one of Silimed’s two manufacturing buildings in Rio de Janeiro, Brazil. The fire occurred
in the building where Sientra’s breast implants are primarily manufactured, or building F2. Silimed has indicated to the Company
that  a  smaller  production  facility  in  Silimed’s  second  building,  or  building  F1,  which  was  not  impacted  by  the  fire,  has  the
potential  to be modified for breast implant  manufacturing.  In order to commence the manufacturing  of breast implants,  certain
areas in building F1 would need to be reconfigured and receive certification and approval by appropriate regulatory bodies. The
Company is working with Silimed to seek clarity as to the near and long-term capabilities of Silimed’s manufacturing operations,
including the status of equipment that is used to manufacture breast implants and the potential feasibility, production capacity and
timing related to Silimed’s ability to manufacture our breast implants.

Recent Developments

On January 27, 2016, after  completing  an analysis and risk assessment,  ANVISA announced their authoriz ation of Silimed to
resume the commercialization and use of its previously manufactured products.  ANVISA concluded there was no evidence to
prove that the presence of surface particles on the silicone implants represented risks which are additional to the ones inherent in
the  product.    However,  Silimed  continues  to  be  suspended  from  manufacturing  and  commercializing  new  batches  of  implants
until an inspection is performed to reassess the fulfillment of its GMP compliance .  

On March 1, 2016, after the completion of extensive independent, third-party testing and analyses of our Breast Products in the
U.S.,  we  lifted  the  temporary  hold  on  the  sale  of  our  devices  manufactured  by  Silimed.    We  also  sent  a  letter  to  our  Plastic
Surgeons informing them of the Company’s market re-entry plans. The conclusive results of our testing indicate no anticipated
significant safety concerns with the use of our products, including our breast implants, consistent with their approval status since
2012.

Components of Operating Results

Net
Sales

We commenced sales of our breast implants in the United States in the second quarter of 2012 and our Breast Products
have historically accounted for substantially all of our net sales. Sales of our Breast Products accounted for 98% ,   97% and 97%
of our net sales for the years ended December 31, 2015 ,   2014 and 2013 , respectively .

54

 
Table of Contents

We recognize revenue, net of sales discounts and estimated returns, as the customer has a standard six-month window to
return purchased products.  There are several uncertainties regarding the recent events involving Silimed that may have a material
unfavorable  impact  on  our  net  sales,  including  the  suspension  of  the  sale  and  manufacturing  of  Silimed’s  products  by  certain
foreign  regulatory  agencies,  our  voluntary  hold  on  the  sale  and  implanting  of  all  Sientra  devices  manufactured  by  Silimed
between October 9, 2015 and March 1, 2016, our uncertainty regarding the resolution of the regulatory inquiries , the delay of
sales  pending  such  resolution  ,  and  our  uncertainty  of  our  customers  responsiveness  to  our  market  re-entry  .  Additionally,  the
recent  fire  at  Silimed’s  facility  that  manufactures  our  breast  implants,  including  the  status  of  equipment  that  is  used  to
manufacture such implants and the potential feasibility, production capacity and timing related to Silimed’s ability to manufacture
breast implants in other facilities, may affect inventory adjustments and have an additional unfavorable impact on our net sales.

We expect that, in the future, assuming a favorable outcome of the aforementioned recent events, that our net sales will
fluctuate on a quarterly basis due to a variety of factors, including seasonality of breast augmentation procedures.  We believe that
breast implant sales are subject to seasonal fluctuation due to breast augmentation patients’ planning their surgery leading up to
the summer season and in the period around the winter holiday season.

Cost
of
Goods
Sold
and
Gross
Margin

Cost of goods sold consists primarily of costs of finished products purchased from our third ‑party manufacturer, reserve

for product warranties and warehouse and other related costs.

Our silicone gel breast implants, tissue expanders and other products are manufactured under an exclusive contract with
Silimed. Under our contract with Silimed, each particular style of implant has a fixed unit cost. In addition to product costs, we
provide  a  commercial  warranty  on  our  silicone  gel  filled  breast  implants.  The  warranty  covers  device  ruptures  in  certain
circumstances.  Estimated  warranty  costs are recorded  at the time  of sale.  Our warehouse  and other  related  costs include  labor,
rent, product shipments from our third party manufacturer and other related costs.

We expect our overall gross margin, which is calculated as net sales less cost of goods sold for a given period divided by
net sales, to fluctuate in future periods primarily as a result of quantity of units sold, manufacturing price increases, the changing
mix of products sold with different gross margins, overhead costs and targeted pricing programs.

Sales
and
Marketing
Expenses

Our sales and marketing expenses primarily consist of salaries, bonuses, benefits, incentive compensation and travel for
our sales, marketing and customer support personnel. Our sales and marketing expenses also include expenses for trade   shows,
our  no  ‑charge  customer  shipping  program  and  no-charge product  evaluation  units ,  as  well  as  educational,  promotional  and
marketing  activities,  including  direct  and  online  marketing.  We  expect  our  sales  and  marketing  expenses  to  fluctuate  in  future
periods as a result of headcount and timing of our marketing programs.  However, we generally expect these costs will increase in
absolute dollars.

Research
and
Development
Expenses

Our  research  and  development,  or  R&D,  expenses  primarily  consist  of  clinical  expenses,  product  development  costs,
regulatory  expenses,  consulting  services,  outside  research  activities,  quality  control  and  other  costs  associated  with  the
development of our products and compliance with Good Clinical Practices, or cGCP, requirements. R&D expenses also include
related  personnel  and  consultant  compensation  and  stock  ‑based  compensation  expense.  We  expense  R&D  costs  as  they  are
incurred.

We  expect  our  R&D  expenses  to  vary  as  different  development  projects  are  initiated,  including  improvements  to  our
existing products, expansions of our existing product lines, new product acquisitions and our FDA ‑required PMA post ‑approval
studies of our breast implants. However, we generally expect these costs will increase in absolute terms over time as we continue
to expand our product portfolio and add related personnel.

General
and
Administrative
Expenses

Our  general  and  administrative,  or  G&A,  expenses  primarily  consist  of  salaries,  bonuses,  benefits  and  stock  ‑based

compensation for our executive, financial, legal, business development and administrative functions. Other G&A expenses

55

 
Table of Contents

include  outside  legal  counsel  and  litigation  expenses,  independent  auditors  and  other  outside  consultants,  corporate insurance,
employee benefits, facilities and information technologies expenses. Beginning in 2013, G&A expenses also include the federal
excise tax on the sale of medical devices in the United States.

In  addition,  for  the  years  ended  December  31,  2015,  2014  and  2013,  we  incurred  $0.0  million,  $0.0  million  and

$1.2 million, respectively, of G&A expenses related to the Grader Street arbitration.

We expect future G&A expenses to increase as we build our finance, legal, information technology, human resources
and other general administration resources to continue to advance the commercialization of our products. In addition, we expect
to incur increased G&A expenses in connection with becoming a public company, which may increase further when we are no
longer able to rely on the “emerging growth company” exemption we are afforded under the Jumpstart Our Business Startups Act,
or the JOBS Act , and legal counsel and litigation expenses in connection with the recently filed lawsuits styled as class actions of
the Company’s stockholders .

Other
(Expense)
Income,
net

Other (expense) income, net primarily consists of interest expense and amortization of debt discount associated with our

term loans and insurance recoveries.

In 2012, the Company filed a claim with the Hartford Insurance Company, or Hartford for reimbursement of legal costs
incurred in connection with litigation with a competitor that was resolved in 2013. The Company held a D&O insurance policy
with Hartford, and the Company and Hartford settled the matter in May 2014. The Company received settlement payments from
Hartford and recovery of costs associated with the litigation of $0 .0 million , $2 .4 million , and $ 0.4 million for the years ended
December 31, 2015, 2014 and 2013, respectively.

Critical Accounting Policies and Significant Judgments and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our financial statements,
which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of
these  financial  statements  requires  management  to  make  estimates  and  judgments  that  affect  the  reported  amounts  of  assets,
liabilities, net sales and expenses and the disclosure of contingent assets and liabilities in our financial statements. We evaluate
our estimates and judgments on an ongoing basis. We base our estimates on 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 our financial
condition  and  results  of  operations  that  are  not  readily  apparent  from  other  sources.  Actual  results  may  differ  from  these
estimates.

While our significant accounting policies are more fully described in Note 2 to our financial statements, we believe that
the  following  accounting  policies  to  be  most  critical  to  the  judgments  and  estimates  used  in  the  preparation  of  our  financial
statements.

Revenue
Recognition

We sell our products directly to customers in markets where we have regulatory approval. We offer a six ‑month return
policy;  and  we  recognize  revenue,  net  of  sales  discounts  and  returns,  in  accordance  with  the  Financial  Accounting  Standards
Board, or FASB, Accounting Standards Codification 605, Revenue Recognition , or ASC 605. ASC 605 requires that six basic
criteria must be met before revenue can be recognized when a right of return exists:

·

·

·

·

·

·

the seller’s price to the buyer is substantially fixed or determinable at the date of sale;

the buyer has paid the seller, or the buyer is obligated to pay the seller and the obligation is not contingent on resale of
the product;

the buyer’s obligation to the seller would not be changed in the event of theft or physical destruction or damage of the
product;

the buyer acquiring the product for resale has economic substance apart from that provided by the seller;

the seller does not have significant obligations for future performance to directly bring about resale of the product by the
buyer; and

the amount of future returns can be reasonably estimated.

56

 
Table of Contents

Appropriate reserves are established for anticipated sales returns based on historical experience, recent gross sales and
any  notification  of  pending  returns.  The  Company  recognizes  revenue  when  title  to  the  product  and  risk  of  loss  transfer  to
customers,  provided there  are no remaining  performance  obligations  required  of the Company or any written matters  requiring
customer acceptance. The Company allows for the return of product from customers within six months after the original sale and
records  estimated  sales  returns  as  a  reduction  of  sales  in  the  same  period  revenue  is  recognized.  Sales  return  provisions  are
calculated based upon historical experience with actual returns. Actual sales returns in any future period are inherently uncertain
and thus may differ from the estimates. If actual sales returns differ significantly from the estimates, an adjustment to revenue in
the current or subsequent period would be recorded. The Company has established an allowance for sales returns of $0.7  million
and $10.0  million as of December 31, 2015 and 2014 , respectively, recorded net against accounts receivable in the balance sheet.

A  portion  of  the  Company’s  revenue  is  generated  from  consigned  inventory  of  breast  implants  maintained  at  doctor,
hospital, and clinic locations. The customer is contractually obligated to maintain a specific level of inventory and to notify the
Company  upon  use.  For  these  products,  revenue  is  recognized  at  the  time  the  Company  is  notified  by  the  customer  that  the
product  has  been  implanted.  Notification  is  usually  through  the  replenishing  of  the  inventory  and  the  Company  periodically
reviews consignment  inventories  to  confirm  accuracy  of  customer  reporting.  FDA  regulations  require  tracking  the  sales  of  all
breast implants.

Warranty
Reserve

We offer a limited warranty and a lifetime product replacement program for our silicone gel breast implants. Under the
limited  warranty  program,  we  will  reimburse  patients  for  certain  out  ‑of ‑pocket  costs  related  to  revision  surgeries  performed
within ten years from the date of implantation in a covered event. Under the lifetime product replacement program, we provide no
‑charge replacement breast implants under a covered event. The programs are available to all patients implanted with our silicone
breast implants after April 1, 2012 and are subject to the terms, conditions, claim procedures, limitations and exclusions. Timely
completion  of  a  device  tracking  and  warranty  enrollment  form  by  the  patient’s  Plastic  Surgeon  is  required  to  activate  the
programs and for the patient to be able to receive benefits under either program.

We recorded expense for the accru al of warranties in the amounts of $0.4 million, $0.5 million and $0.4 million, for the
years  ended  December  31,  2015,  2014  and  2013  ,   respectively.  As  of  December  31,  2015  and  2014,  we  held  total  warranty
liabilities of $1.3 million and $1.0 million, respectively.

Stock
‑‑Based
Compensation

Stock ‑based compensation cost is measured at the date of grant based on the estimated fair value of the award, net of
estimated forfeitures. We estimate the fair value of our stock ‑based awards to employees and directors using the Black ‑Scholes
option pricing model.  The grant  date fair  value  of a stock  ‑based  award is  recognized  as  an  expense  over  the requisite  service
period of the award on a straight ‑line basis.

The Black ‑Scholes model requires the input of subjective assumptions, including the risk ‑free interest rate, expected
dividend yield, expected volatility and expected term, among other inputs. These estimates involve inherent uncertainties and the
application  of  management’s  judgment.  If  factors  change  and  different  assumptions  are  used,  our  stock  ‑based compensation
expense could be materially different in the future.

We recorded total non ‑cash stock ‑based compensation expense of $2.4 million, $0.6 million and $0.3 million for the
years ended December 31, 2015, 2014 and 2013, respectively. As of December 31, 2015 we had total unrecognized compensation
costs of $4.7 million related to our stock options and employee stock purchase plan. These costs are expected to be recognized
over a weighted average period of 2.95 years.

Warrant
Liabilities

We have issued warrants to Oxford to purchase shares of common stock in connection with our term loan agreement.
The warrants are recorded at fair value using either the Black ‑Scholes option pricing model, other binomial valuation model or
lattice model, depending on the characteristics of the warrants at the time of the valuation. The fair value of these warrants is re
‑measured  at  each  financial  reporting  period  with  any  changes  in  fair  value  being  recognized  as  a  component  of  other  income
(expense) in the accompanying statements of operations. We will continue to re ‑measure the warrants to fair value until exercise
or expiration of the related warrant. 

57

 
Table of Contents

As  of  December  31,  2015  and  2014,  the  fair  value  of  our  warrant  liability  was  $0.0  million  and  $0.4  million,
respectively. We recognized a decrease of other (income) expense of $0.4 million for the change in fair value of warrants during
the year ended December 31, 2015, and an increase of $0.2 million and $0.0 million for the years ended D e cember 31, 2014 and
2013, respectively.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of net assets of purchased businesses. Goodwill
is  not  amortized,  but  instead  subject  to  impairment  tests  on  at  least  an  annual  basis  and  whenever  circumstances  suggest  that
goodwill may be impaired.  Our annual test for impairment is performed as of October 1 of each fiscal year, pursuant to which we
make  a  qualitative  assessment  of  whether  it  is  more  likely  than  not  that  a  reporting  unit’s  fair  value  is  less  than  its  carrying
amount before applying the two-step goodwill impairment test. If we conclude that it is not more likely than not that the fair value
of a reporting unit is less than its carrying amount, we are not required to perform the two-step impairment test for that reporting
unit.

Under the first step of the test, we are required to compare the fair value of a reporting unit with its carrying amount,
including  goodwill.  If  the  fair  value  of  a  reporting  unit  exceeds  its  carrying  amount,  goodwill  of  the  reporting  unit  is  not
considered impaired and the second step of the test is not performed. If the results of the first step of the impairment test indicate
that the fair value of a reporting unit does not exceed its carrying amount, then the second step of the test is required. The second
step  of  the  test  compares  the  implied  fair  value  of  the  reporting  unit  goodwill  with  the  carrying  amount  of  that  goodwill.  The
impairment loss is measured by the excess of the carrying amount of the reporting unit goodwill over the implied fair value of that
goodwill.

On September 24, 2015, we experienced a significant decline in our common stock price, which was sustained through
September  30,  2015.  The  significant  decline  in  our  common  stock  price  for  a  sustained  period,  along  with  the  impact  from
regulatory inquiries related to medical devices manufactured by Silimed, our contract manufacturer, were identified as potential
indicators of impairment of goodwill and other intangibles. As a result, we were required to assess whether or not an impairment
of  our  goodwill  had  occurred  as  of  Septembe  r  30,  2015.  We  assessed  the  impact  of  the  recent  downward  volatility  in  our
common  stock  price  and  concluded  that  the  sustained  decline  constituted  a  triggering  event  requiring  an  interim  goodwill
impairment test. We conducted the first step of the goodwill impairment test described above for our single reporting unit as of
September  30, 2015. The  fair  value  of the  reporting  unit exceeded  its  carrying  value  as of September  30, 2015 by 24.7%, and
therefore goodwill was determined to not be impaired as of September 30, 2015.

However, a s a result of the events described in  “ Silimed Related Developments ”, adverse changes in operating results,
an  extended  period  of  our  common  stock  trading  significantly  below  book  value  per  share,  and  unfavorable  changes  in  c
ircumstances related to Silimed, we identified additional impairment indicators during the quarter ended December 31, 2015 . 

For  the  quarter  ended  December  31,

 we  performed  a  step  one  analysis  for  possible  goodwill
impairment.    Determining  the  fair  value  of  the  Company  as  a  single  reporting  unit  as  part  of  the  step  one  analysis  involves
significant judgment.  For step one, we used a market approach to determine fair value and concluded that the carrying value of
the reporting unit exceeded the estimated fair value, and thus performed the step two analysis.  For step two, we compared the
implied fair value of the Company’s goodwill with the carrying value of goodwill. 

 2015,

The  implied  fair  value  of  goodwill  is  determined  in  the  same  manner  as  goodwill  that  is  recognized  in  a  business
combination.  Significant judg ments and estimates are involved in the determination of the fair value of the assets and liabilities
of the reporting unit, and therefore directly impact the implied fair value of goodwill, as part of the step two analysis.  The most
significant estimates involved relate to the fair value of intangible asset s. We estimated the value of the intangible asset s using a
discounted cash flow approach considering market comparable transactions. Th ese estimates are highly subjective and involve
many judgments . 

For the quarter ended December 31, 2015, we recorded a goodwill impairment charge of $14.3 million.  For additional

information on the goodwill impairment see Note 5 to the “Notes to Financial Statements ” included herein .

Recent Accounting Pronouncements

In May 2014, the FASB issued accounting standard update, or ASU, 2014-09, Revenue from Contracts with Customers
.  The standard was issued to provide a single framework that replaces existing industry and transaction specific U . S . GAAP
with a five step analysis of transactions to determine when and how revenue is recognized.  The accounting standard update will
replace  most  existing  revenue  recognition  guidance  in  U  . S . GAAP when it  becomes  effective.    In August  2015,  the  FASB
issued  ASU  2015-14,      Revenue  from  Contracts  with  Customers  (Topic  606):  Deferral  of  the  Effective  Date,   t  o  defer  the
effective date of ASU 2014-09 by one year.  Therefore, ASU 2014-09 will become effective for the Company beginning in fiscal
year 2018. Early adoption would be permitted for the Company beginning in fiscal year 2017. The standard permits the use of
either  the  retrospective  or  cumulative  transition  method.  The  Company  is  currently  evaluating  the  accounting,  transition  and
disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.

In April 2015, the FASB issued accounting standard update 2015-03 , Interest — Imputation of Interest .  The standard
was issued to  simplify  the  presentation  of debt  issuance  costs  and  require  that  debt issuance  costs  related  to  a recognized  debt
liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt
discounts.    This  accounting  standard  update  will  be  effective  for  the  Company  beginning  in  fiscal  year  2016.    The  Company
anticipates there will be no material impact on its financial statement upon adoption of this guidance.

In April 2015, the FASB issued accounting standard update 2015-05 , Intangibles — Goodwill and Other — Internal-
Use Software .  The standard was issued to provide guidance to customers about whether a cloud computing arrangement includes
a  software  license.    If  a  cloud  computing  arrangement  includes  a  software  license,  then  the  customer  should  account  for  the
software  license  element  of  the  arrangement  consistent  with  the  acquisition  of  other  software  licenses.    If  a  cloud  computing
arrangement  does  not  include  a  software  license,  the  customer  should  account  for  the  arrangement  as  a  service  contract.    This
accounting standard update will be effective for the Company beginning in fiscal year 2016.  The Company anticipates there will
be no material impact on its financial statement upon adoption of this guidance.

In  July  2015,  the  FASB  issued  accounting  standard  update  2015-11  ,  Inventory  —  Simplifying  the  Measurement  of
Inventory .  The standard simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower
of cost and net realizable value, thereby simplifying the current guidance under which an entity must measure inventory at the
lower of cost or market. The accounting standards update will not apply to inventories that are measured by using either the last-
in, first-out method or the retail inventory method. This accounting standard update will be effective for the Company beginning
in fiscal  year 2017. The Company anticipates  there will be no material  impact  on its financial  statement  upon adoption of this
guidance.

In November 2015, the FASB issued accounting standard update 2015-17, Income Taxes – Balance Sheet Classification
of  Deferred  Taxes.  The  standard  simplifies  the  presentation  of  deferred  income  taxes  by  requiring  deferred  tax  assets  and
liabilities be classified as noncurrent in a classified statement of financial position. Current GAAP requires an entity to separate
deferred income tax liabilities and assets into current and noncurrent amounts. This accounting standard update will be effective
for  the  Company  beginning  in  fiscal  year  2017.  The  Company  anticipates  there  will  be  no  material  impact  to  its  financial
statement upon adoption of this guidance.

In February 2016, the FASB issued accounting standard update 2016-02, Leases (Topic 842) which supersedes FASB
Accounting Standard Codification Leases (Topic 840). The standard is intended to increase the transparency and comparability
among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about
leasing  arrangements.  This  accounting  standard  update  will  be  effective  for  the  Company  beginning  in  fiscal  year  2019.  The
Company  is  currently  evaluating  the  impact  that  adoption  of  the  standard  will  have  on  the  financial  statements  and  related
disclosures.

Net sales decreased $6.6  million, or  14.8% , to $38.1  million for the year ended  December 31, 2015 , as compared to
$44.7  million for the year ended December 31, 2014 . This decrease was primarily driven by our voluntary hold on the sale and
implanting of all Sientra devices manufactured by Silimed on October 9, 2015.  

There  are  several  uncertainties  regarding  the  recent  events  involving  Silimed  that  may  have  a  material  unfavorable
impact  on  our  net  sales,  including  the  suspension  of  the  sale  and  manufacturing  of  Silimed’s  products  by  certain  foreign
regulatory  agencies,  our  voluntary  hold  on  the  sale  and  implanting  of  all  Sientra  devices  manufactured  by  Silimed  between
October 9, 2015 and March 1, 2016 , our uncertainty regarding the resolution of the regulatory inquiries and the delay of sales
pending  such  resolution.  Additionally,  the  recent  fire  at  Silimed’s  facility  that  manufactures  our  breast  implants,  including  the
status of equipment that is used to manufacture such implants and the potential feasibility, production capacity and timing related
to Silimed’s  ability  to  manufacture  breast  implants  in other  facilities,  may  affect  inventory  adjustments  and have  an additional
unfavorable impact on our net sales.

As  of  December  31,  2015,  our  sales  organization  included  51  employees,  as  compared  to  46  employees  as  of

December 31, 2014.

Cost
of
Goods
Sold
and
Gross
Margin

Cost of goods sold decreased   $0.8  million,  or  7.4% , to $10.7  million  for  the  year  ended  December  31, 2015  , as
compared to $11.5  million for the year ended December 31, 2014 . This decrease was primarily due to a decrease in sales volume
driven by our voluntary hold on sales.

The gross margins for the years ended December 31, 2015 and 2014 were 72.0% and 74.3% , respectively. The decrease
in gross margin was primarily due to an incremental $0.3 million reserve for inventory obsolescence recorded in the third quarter
for product that we estimate to expire prior to being sold, greater fixed overhead as a percentage of net sales, and manufacturing
cost increases.

2015 , as compared to $23.6  million for the year ended December 31, 2014 . This was primarily due to a $3.2 million increase in
employee related expense s for the sales department offset by a $0.9 million decrease in marketing costs.

Research
and

G&A  expenses  increased      $8.0   million,  or  74.9%  ,  to  $18.7   million  for  the  year  ended  December  31,  2015  ,  as
compared to $10.7  million for the year ended December 31,  2014 . This increase was primarily due to an increase in expenses
that relate to   operating as a public company , termination benefits for certain former executives , and outside legal counsel costs.

Net  sales  increased  $9.6  million,  or  27.2%,  to  $44.7  million  for  the  year  ended  December  31,  2014,  as  compared  to
$35.2 million for the year ended December 31, 2013. This increase was primarily driven by sales of our Breast Products in the
United States resulting from increased sales and marketing activities and boarder adoption of Sientra’s product offerings by board
‑certified  Plastic  Surgeons.  As  of  December  31,  2014,  our  sales  organization  included  46  employees,  as  compared  to  39
employees as of December 31, 2013.

Cost

Cost  of  goods  sold  increased  $2.9  million,  or  33.8%,  to  $11.5  million  for  the  year  ended  December  31,  2014,  as

compared to $8.6 million for the year ended December 31, 2013. This increase was primarily due to an increase in sales volume.

The gross margins for the years ended December 31, 2014 and 2013 were 74.3% and 75.6%, respectively. The decrease
in gross margin was primarily due to a manufacturing price increase, and the launch of new line extension in the fourth quarter,
offset by holding fixed overhead relatively constant.

Sales
and
Marketing
Expenses

Sales and marketing expenses increased $1.4 million, or 6.2%, to $23.6 million for the year ended December 31, 2014,
as  compared  to  $22.2  million  for  the  year  ended  December  31,  2013.  This  was  primarily  due  to  a  $1.8  million  increase  in
employee related expense for the sales department offset by a $0.4 million decrease in marketing costs.

Research
and
Development
Expenses

R&D expenses increased $0.2 million, or 5.1%, to $4.7 million for the year ended December 31, 2014, as compared to
$4.5 million for the year ended December 31, 2013. This was primarily due to an increase in employee related expenses and costs
associated with our PMA post ‑approval requirements.

G&A expenses decreased $7.4 million, or 40.7%, to $10.7 million for the year ended December 31, 2014, as compared
to  $18.1  million  for  the  year  ended  December  31,  2013.  This  decrease  was  primarily  due  to  the  $10.1  million  decrease  in
litigation expenses related to the Mentor litigation , partially offset by an increase in expenses related to accounting related costs
and federal excise tax.

Other
(Expense)
Income,
net

Total other (expense) income, net for the year ended December 31, 2014 was primarily associated with interest expense
on our term loans of $2.2 million and income from recovery of costs associated with the Mentor litigation of $2.4 million. Total
other (expense) income, net for the year ended December 31, 2013 was primarily associated with interest expense on our term
loans of $0.9 million.

Liquidity and Capital Resources

Since our inception, we have incurred significant net operating losses and anticipate that our losses will continue in the
near  term.  We  expect  our  operating  expenses  will  continue  to  grow  as  we  expand  our  operations.  We  will  need  to  generate
significant  net sales to achieve profitability. To date, we have funded our operations primarily with proceeds from the sales of
preferred stock, borrowings under our term loans, sales of our products since 2012, and the proceeds from the sale of our common
stock  in  our  initial  public  offering  and recent  follow-on offering  .  To  date,  we  have  received  gross  proceeds  from  the  sales  of
preferred  stock  totaling  $151.0  million.  We  issued  and  sold  preferred  stock  for  aggregate  gross  proceeds  of  $65.0  million  in
March 2012, which was our most recent issuance and sale of preferred stock. As of December 31, 201 5 , we had no long-term
debt.

On November 3, 2014, we completed our IPO of common stock in which we sold 5,000,000 shares at a price of $15.00
per share. Additionally, the underwriters exercised their option to purchase an additional 750,000 shares at $15.00 per share. As a
result  of  our  IPO, we  raised  a  total  of  approximately  $77.0 million  in  net  proceeds  after  deducting  underwriting  discounts  and
commissions of approximately $6.0 million and offering expenses of approximately $3.2 million. Costs directly associated with
our  IPO  were  capitalized  and  recorded  as  deferred  IPO  costs  in  other  current  assets  prior  to  the  completion  of  our  IPO.  Upon
completion  of  the  IPO,  the  issuance  costs  were  reclassified  to  additional  ‑paid  ‑in  capital  to  offset  the  IPO  proceeds.  Upon
completion of our IPO, all outstanding shares of our convertible preferred stock were converted into 8,942,925 shares of common
stock.

On  September  23,  2015,  we  completed  our  follow-on  public  offering  of  common  stock  in  which  we  sold  3,000,000
shares at a price of $22.00 per share. As a result of our follow-on offering, we raised a total of approximately $61.4 million in net
proceeds  after  deducting  underwriting  discounts  and  commissions  of  approximately  $4.0  million  and  offering  expenses  of
approximately $0.6 million.

As  of  December  31,  2015 ,  we  had  $112.8  million  in  cash  and  cash  equivalents.  Our  historical  cash  outflows  have
primarily been associated with research and development activities, especially related to obtaining FDA approval for our breast
implant  portfolio  and  complying  with  the  FDA’s  post-approval  requirements,  the  Mentor  litigation,  activities  relating  to
commercialization  and  increases  in  working  capital,  including  the  purchase  of  inventory  as  well  as  the  expansion  of  our  sales
force and marketing programs.  We believe that our available cash on hand will be sufficient to satisfy our liquidity requirements
for at least the next 12 months. However, we expect that the recent events involving Silimed, including our voluntary hold on the
sale and implanting of all Sientra devices manufactured by Silimed between October 9, 2015 and March 1, 2016 , our uncertainty
regarding  the  amount  of  additional  expenses  we  may  incur  in  connection  with  regulatory  inquiries  and  our  own  review  and
testing,  as  well  as  expenses  we  may  incur  in  connection  with  reestablishing  our  inventory  supply  as  a  result  of  the  fire  in
Silimed’s manufacturing facility and expenses we may incur defending against litigation claims, may have a material effect on
our  future  cash  outflows  and  Sientra’s  liquidity.  Additionally,  on  October  28,  2015,  following  our  repayment of  all  principal,
interest,  other  amounts  and  obligations  owed to Oxford under  the  term  loans for a total  of $24.5 million,  the Company has no
outstanding debt obligations. As a result of the recent events and the resulting potential demands on Sientra’s liquidity, we may be
required to seek additional funds in the future from public or private offerings of our capital stock, borrowings under term loans
or other sources.

Net cash used in operating activities was $18.2 million during the year ended December 31, 2015 as compared to net
cash  provided  by operating  activities  of  $0.5  million  during  the  year  ended  December  31, 2014.  The  $18.6 million  increase  in
cash used in operating activities between the years ended December 31, 2015 and 2014 was primarily associated with the increase
in  net  loss  of  $35.4  million,  which  was  affected  by  our  voluntary  hold  on  the  sale  and  implanting  of  all  Sientra  devices
manufactured  by  Silimed  since  October  9,  2015  ,  offset  by  a  decrease  in  cash  outflows  from  operating  assets  and  liabilities
resulting from a decrease in inventory purchases and timing of accounts payable payments.

Cash
used
in

activities

Net  cash  used  in  investing  activities  was  $1.1  million  during  the  year  ended  December  31,  2015  as  compared  to
$0.4 million during the year ended December 31, 2014. The increase in cash used in investing activities of $0.7 million between
the years ended December 31, 2015 and 2014 was primarily due to an increase in property and equipment purchases.

Cash
provided
by
financing
activities

Net cash provided by financing activities was $35.4 million during the year ended December 31, 2015 as compared to
$87.0 million during the year ended December 31, 2014. The decrease in cash provided by financing activities of $51.6 million
between the years ended December 31, 2015 and 2014 was primarily the result of the decrease in cash proceeds from the issuance
of our common stock, net of the underwriters discount in the IPO of $80.2 million during the year ended December 31, 2014, in
comparison  to  the  cash  proceeds  from  the  issuance  of  our  common  stock,  net  of  the  underwriters  discount  in  the  follow-on
offering  of  $62.0  million  during  the  year  ended  December  31,  2015,  and  further  offset  by  the  repayment  of  long-term  debt  of
$26.6 million during the year ended December 31, 2015.  

Our  liquidity  position  and  capital  requirements  are  subject  to  a  number  of  factors.  For  example,  our  cash  inflow  and

outflow may be impacted by the following:

·

·

·

·

·

·

·

our continued ability to rely on Silimed to manufacture and supply our silicone gel breast implants, tissue expanders and
other products or the timing and availability of alternative manufacturing sources ;

net sales generated by our Breast Products and any other future products that we may develop and commercialize;

costs associated with expanding our sales force and marketing programs;

cost associated with developing and commercializing our proposed products or technologies;

cost of obtaining and maintaining regulatory clearance or approval for our current or future products;

cost of ongoing compliance with regulatory requirements;

expenses we incur in connection with potential litigation or governmental investigations;

·

·

anticipated or unanticipated capital expenditures; and

unanticipated G&A expenses.

Our primary short ‑term capital needs, which are subject to change, include expenditures related to:

·

·

cost of ongoing compliance with recent regulatory inquiries involving Silimed;

costs associated with our own review and testing at Silimed’s manufacturing facilities and of our own inventory;

·
 expenses  we  incur  in  connection  with  defending  against  the  lawsuits  filed  against  us  alleging  violations  of  the
Exchange  Act  and  the  Securities  Act  in  connection  with  allegedly  false  and  misleading  statements  concerning
Sientra’s business, operations, and prospects;

·

·

·

·

support of our sales and marketing efforts related to our current and future products;

new product acquisition and development efforts;

facilities expansion needs ; and

investment in inventory required to meet customer demands .

Although we believe the foregoing items reflect our most likely uses of cash in the short-term, we cannot predict with
certainty  all of our particular  short-term  cash  uses or the timing  or amount of cash used.  If cash generated  from operations  is
insufficient to satisfy our working capital and capital expenditure requirements, we may be required to sell additional equity or
debt securities or obtain additional credit facilities.  Additional capital, if needed, may not be available on satisfactory terms, if at
all.  Furthermore, any additional equity financing may be dilutive to stockholders, and debt financing, if available, may include
restrictive covenants.  For a discussion of other factors that may impact our future liquidity and capital funding requirements, see
“Risk Factors — Risks Related to Our Financial Results.”

Indebtedness

Term
Loan
Agreement

On January 17, 2013, we entered into a Loan and Security Agreement with Oxford, which was amended and restated on

June 30, 2014, or the Amended Term Loan Agreement.

In connection with the Amended Term Loan Agreement, we issued to Oxford (i) seven ‑year warrants in January 2013
to purchase shares of our common stock with a value equal to 3.0% of the tranche A, B and C term loans amounts and (ii) seven
‑year  warrants  in  June  2014  to  purchase  shares  of  our  common  stock  with  a  value  equal  to  2.5%  of  the  tranche  D  term  loan
amount. The warrants have an exercise price per share of $14.671.

On  October  27,  2015,  Oxford  issued  a  notice  to  the  Company  indicating  that,  in  connection  with  the  recent  events
involving Silimed and the Company, certain events of default have occurred and continue to exist under the Amended Term Loan
Agreement. On October 28, 2015, we repaid all principal, interest, other amounts and obligations owed to Oxford under the term
loans for a total of $24.5 million, following which the Company has no outstanding debt obligations.

Item 8.  Financial Statements and Supplementary Dat a

The financial statements required to be filed pursuant to this Item 8 are appended to this report beginning on page F ‑1.

An index of those financial statements is included in Part IV, Item 15 below.

Item 9.  Changes in and Disagreements with Accountant s on Accounting and Financial Disclosure

PricewaterhouseCoopers LLP, or PwC, was previously our independent auditors since 2007. On December 13, 2013, we
dismissed PwC and KPMG LLP was engaged as our independent auditors. The decision to change our independent auditors was
approved by our board of directors.

During the years ended December  31, 2011 and 2012 and the subsequent interim  period through December 13, 2013,
there were no (i) disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure, or
auditing  scope  or  procedures  which  disagreements  if  not  resolved  to  PwC’s  satisfaction  would  have  caused  them  to  make
reference thereto in their reports on the financial statements for such years, or (ii) reportable events as defined in Item 304(a)(1)
(v) of Regulation S ‑K, except as described below. PwC did not issue any audit reports for the years ended December 31, 2012
and 2013.

During October 2013, PwC notified us that it was in disagreement with our revenue recognition policies relating to the
timing  of  revenue  recognition  given  our  terms  and  conditions  and  practices  regarding  returns.  The  subject  matter  of  this
disagreement  was  not  discussed  between  our  board  of  directors  and  PwC  prior  to  PwC’s  dismissal.  We  authorized  PwC  to
respond fully to the inquiries of KPMG LLP concerning the subject matter of this disagreement. We requested PwC to provide us
with a letter addressed to the SEC stating whether or not PwC agrees with the above disclosures. A copy of PwC’s letter, dated
September 1, 2015 , is attached as Exhibit 16.1 to the registration statement on Form S ‑1 filed with the SEC on September 3,
2015 .

KPMG LLP audited our financial statements for the years ended December 31, 2012 and 2013 and the audit reports of
KPMG LLP for such years did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as
to  uncertainty,  audit  scope  or  accounting  principles.  During  the  two  fiscal  years  ended  December  31,  2012  and  through  the
subsequent interim period prior to KPMG LLP becoming the Company’s independent auditors, the Company did not consult with
KPMG LLP on either (i) the application of accounting principles to a specified transaction, either completed or proposed, (ii) the
type of audit opinion that may be rendered on the Company’s financial statements; or (iii) any matter that was either the subject of
a disagreement, as defined in Item 304(a)(1)(iv) of Regulation S ‑K, or a reportable event. We are unable to quantify the impact
of  the  matters  subject  to  the  disagreement  and  cannot  state  what  the  effect  on  our  financial  statements  would  have  been  as  an
evaluation of such matters was not completed prior to the dismissal of our former independent auditors.

Item 9A.  Controls and Procedure s

Evaluation
of
Disclosure
Controls
and
Procedures

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated
the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10
‑K. The term “disclosure controls and procedures,” as defined in Rules 13a ‑15(e) and 15d ‑15(e) under the Exchange Act means
control and other procedures of a company that are designed to ensure that information required to be disclosed by a company in
the  reports  that  it  files  or  submits  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported,  within  the  time
periods  specified  in  the  SEC  rules  and  forms.  Disclosure  controls  and  procedures  include,  without  limitation,  controls  and
procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under
the  Exchange  Act  is  accumulated  and  communicated  to  the  company’s  management,  including  its  principal  executive  and
principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our
disclosure controls and procedures as of December 31, 2015 , our principal executive officer and principal financial officer have
concluded that as of such date, 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 such term is
defined in Exchange Act Rule 13a-15(f). Internal control over financial reporting is a process designed under the supervision and
with  the  participation  of  our  management,  including  our  principal  executive  officer  and  principal  financial  officer,  to  provide
reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external
purposes in accordance with accounting principles generally accepted in the United States of America.

As of  December  31, 2015,  our  management  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting
using  the  criteria  set  forth  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  in  Internal  Control-
Integrated Framework , or the 2013 Framework. Based on this assessment, our management concluded that, as of December 31,
2015, our internal control over financial reporting was effective based on those criteria .

Inherent
Limitations
of
Internal
Controls

Our  management,  including  our  principal  executive  officer  and  principal  financial  officer  ,  does  not  expect  that  our
disclosure  controls  and  procedures  or  our  internal  controls  will  prevent  or  detect  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.  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, within the Company 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 control. 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  the  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.

Changes
in
Internal
Control
over
Financial
Reporting

There  were no changes  in our internal  control  over  financial  reporting  during our most recent  fiscal  quarter  that  have

materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 9B.  Other Informatio n

On March 7, 2016, our board of directors adopted the Sientra, Inc. Inducement Plan, or the Inducement Plan, pursuant to
which we reserved 180,000 shares of our common stock for issuance under the Inducement Plan. The Inducement Plan provides
for the grant of stock options and restricted stock unit awards. The only persons eligible to

67

 
Table of Contents

receive grants of stock awards under the Inducement Plan are individuals who satisfy the standards for inducement grants under
NASDAQ Marketplace Rule 5635(c)(4) and the related guidance under NASDAQ IM 5635-1. A person who previously served as
an  employee  or  director  of  the  Company  will  not  be  eligible  to  receive  stock  awards  under  the  Inducement  Plan,  other  than
following  a  bona  fide  period  of  non-employment.  Our  board  of  directors  or  a  duly  authorized  committee  has  the  authority  to
administer  the Inducement  Plan, provided however, that  the grant  of stock  awards under the Inducement  Plan must be granted
either by our independent compensation committee or a majority of our independent directors within the meaning of Rule 5605(a)
(2) of the NASDAQ Listing Rules. The foregoing description of the terms of the Inducement Plan is qualified in its entirety by
reference to the Inducement Plan and forms of award agreements thereunder, which is filed with this Annual Report on Form 10-
K as exhibit 10.20 and incorporated herein by reference.

Report of Independent Registered Public Accounting Fir m

The Board of Directors and Stockholders
Sientra, Inc. :

We have audited the accompanying balance sheets of Sientra, Inc. (the Company) as of December 31, 2015 and 2014,
and the related statements of operations, convertible preferred stock and stockholders’ equity (deficit), and cash flows for each of
the years in the three ‑year period ended December 31, 2015. In connection with our audits of the financial statements, we also
have  audited  the  related  financial  statement  schedule  II  –  valuation  and  qualifying  accounts.  These  financial  statements  and
financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on
these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United
States).  Those standards  require  that we plan  and perform  the  audit  to obtain  reasonable  assurance  about whether  the financial
statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates
made  by  management,  as  well  as  evaluating  the  overall  financial  statement  presentation.  We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion, the financial statements and financial statement schedule referred to above present fairly, in all material
respects, the financial position of Sientra, Inc. as of December 31, 2015 and 2014, and the results of its operations and its cash
flows  for  each  of  the  years  in  the  three  ‑year  period  ended  December  31,  2015,  in  conformity  with  U.S.  generally  accepted
accounting principles.

S ientra , I nc .

Notes to Financial Statements

  ( i n thousands, except per share data )

1) Formation and Business of the Company

(a)

Formation

Sientra,  Inc.,  or  the  Company,  was  incorporated  in  the  State  of  Delaware  on  August  29,  2003  under  the  name  Juliet
Medical, Inc. and subsequently changed its name to Sientra, Inc. in April 2007. The Company acquired substantially all the assets
of  Silimed,  Inc.,  or  Silimed,  on  April  4,  2007.  The  purpose  of  the  acquisition  was  to  acquire  the  rights  to  the  silicone  breast
implant clinical trials. Following this acquisition, the Company focused on completing the clinical trials to gain Food and Drug
Administration, or FDA, approval to offer its silicone gel breast implants in the United States.

In  March  2012,  Sientra  announced  it  had  received  approval  from  the  FDA  for  its  portfolio  of  silicone  gel  breast
implants, and in the second quarter of 2012 the Company began commercialization efforts to sell its products in the United States.
The Company, based in Santa Barbara, California, is a medical aesthetics company that focuses on serving board-certified plastic
surgeons and offers a portfolio of silicone shaped and round breast implants, tissue expanders, and body contouring products.

(b)

Reverse
Stock
Split

On  October  10,  2014,  the  board  of  directors  and  stockholders  approved  an  amendment  to  the  Company’s  fourth
amended and restated certificate of incorporation, which was filed on October 17, 2014, which effected a 2.75 -to-1 reverse stock
split of the Company’s issued and outstanding shares of common stock. The par value of the common stock was not adjusted as a
result of the reverse stock split. All issued and outstanding shares of common stock, stock options and warrants and the related
per share amounts contained in the Company’s financial statements have been retroactively adjusted to reflect this reverse stock
split for all periods presented. Also, as a result of the reverse stock split of the common stock, the conversion ratios for all of the
Company’s  convertible  preferred  stock  have  been  adjusted  such  that  the  preferred  stock  are  now  convertible  into  shares  of
common  stock  at  a  conversion  rate  of  2.75 -to-1  instead  of  1 -to-1.  The  number  of  issued  and  outstanding  shares  of  preferred
stock and their related per share amounts have not been affected by the reverse stock split and therefore have not been adjusted in
the Company’s financial statements. However, to the extent that the convertible preferred stock are presented on an as converted
to  common  stock  basis,  such  share  and  per  share  amounts  contained  in  the  Company’s  financial  statements  have  been
retroactively adjusted to reflect this reverse stock split for all periods presented.

(c)

Initial
Public
Offering

On November 3, 2014, the Company completed an initial public offering, or IPO, whereby it sold a total of 5,750,000
shares of common stock at $15.00 per share inclusive of 750,000 shares sold to underwriters for the exercise of their option to
purchase  additional  shares.    The  Company  received  net  proceeds  from  the  IPO  of  approximately  $77,035  ,  after  deducting
underwriting discounts and commissions and offering expenses of approximately $9,215 .  These expenses were recorded against
the proceeds received from the IPO.

The interest-only period for the tranche D term loan (see Note 4) was extended from August 1, 2015 to August 1, 2016

as a result of having raised at least $50,000 in gross proceeds in the IPO and the completion of the IPO before June 30, 2015.

The outstanding shares of convertible preferred stock were converted on a 2.75 -to-1 basis into shares of common stock
concurrent with the closing of the IPO. All of the outstanding shares of Series A, Series B and Series C preferred stock converted
into 8,942,925 shares of common stock. Following the closing of the IPO, there were no shares of preferred stock outstanding.

Follow-on
Offering

On  September  23,  2015,  the  Company  closed  a  follow-on  public  offering,  whereby  it  sold  3,000,000  shares  of  its
common stock, at a price to the public of $22.00 per share. The Company received net proceeds from the follow-on offering of
approximately  $61,397  ,  after  deducting  underwriting  discounts  and  commissions  of  $3,960  and  offering  expenses  of
approximately $643 .

(e)

Regulatory
Inquiries
Regarding
Products
M
anufactured
by
Silimed

There  have  been  recent  regulatory  inquiries  related  to  medical  devices  manufactured  by  Silimed  Industria  de
Implantes  Ltda.  (formerly,  Silimed-Silicone  e  Instrumental  Medico-Cirugio  e  Hospitalar  Ltda.),  or  Silimed,  the  Company’s
contract manufacturer.

On September 23, 2015, the Medicines and Healthcare Products Regulatory Agency, or MHRA, an executive agency of
the United Kingdom, or U.K., issued a press release announcing the suspension of sales and implanting in the U.K. of all medical
devices manufactured by Silimed following the suspension of the CE certificate of these products issued by TUV SUD, Silimed’s
notified body under European Union, or EU, regulation. The suspension of Silimed’s CE certificate by TUV SUD followed TUV
SUD’s inspection at Silimed’s manufacturing facilities in Brazil, relating to particles on Silimed breast products . Breast implants
have stringent standards for manufacturing and robust quality systems, but there is no specific or defined standard for particles on
breast implants. MHRA noted that no risks to patient health have been identified in connection with implanting Silimed products,
and, accordingly, there is no need to adopt any procedure or action for those patients who have received them.

On October 2, 2015, the Brazilian regulatory agency ANVISA and the Department of the Secretary of State of the State
of  Rio  de  Janeiro  announced  that  while  they  continue  to  review  the  technical  compliance  related  to  GMP  of  Silimed’s
manufacturing  facility,  and  as  a  precautionary  measure  ,  they  temporarily  suspended  the  manufacturing  and  shipment  of  all
medical devices made by Silimed, including products manufactured for Sientra. ANVISA reiterated that no risks to patient health
have been identified in connection with implanting Silimed products, and, accordingly, there is no need to adopt any procedure or
action for those patients who have received them. Furthermore, ANVISA also indicated that, based on their contact to date with
foreign regulatory authorities, there have been no reports of adverse events related to the use of Silimed products.

On October 9, 2015, the Company voluntarily placed a hold on the sale of all Sientra devices manufactured by Silimed
and  recommended  that  plastic  surgeons  discontinue  implanting  the  devices  until  further  notice.    The  Company  had  ongoing
discussions with the FDA regarding European and Brazilian regulatory inquiries into Silimed products, and conduct ed its own
review  of  the  matter  with  the  assistance  of  independent  experts  in  quality  management  systems,  GMP  and  data-based  risk
assessment.    The  FDA  also  reiterated  that  no  reports  of  adverse  events  and  no  risks  to  patient  health  had  been  identified  in
connection with this issue .

On  January  27,  2016,  after  completing  an  analysis  and  risk  assessment,  ANVISA  announced  their  authoriz  ation  of
Silimed  to  resume  the  commercialization  and  use  of  its  previously  manufactured  products.    ANVISA  concluded  there  was  no
evidence to prove that the presence of surface particles on the silicone implants represented risks which are additional to the ones
inherent in the product.  However, Silimed continues to be suspended from manufacturing and commercializing new batches of
implants until an inspection is performed to reassess the fulfillment of its GMP compliance .  

On  March  1,  2016,  after  the  completion  of  extensive  independent,  third-party  testing  and  analyses  of  its  devices
manufactured by Silimed, the Company lifted the temporary hold on the sale of such devices.  The Company also sent a letter to
Plastic  Surgeons  informing  them  of  the  Company’s  market  re-entry  plans.  The  conclusive  results  of  the  Company’s  testing
indicate no anticipated significant safety concerns with the use of its products, including its breast implants, consistent with their
approval status since 2012.

(2) Summary of Significant Accounting Policies

(a)
Basis
of
Presentation
and
Use
of
Estimates

The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of
America,  or  GAAP,  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and
liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts
of  revenues  and  expenses  during  the  reporting  period.  Actual  results  could  differ  from  those  estimates.  Assets  and  liabilities
which are subject to significant judgment and use of estimates include the allowance for doubtful accounts, sales return reserves,
provision  for  warranties,  valuation  of  inventories,  recoverability  of  long-lived  assets,  valuation  allowances  with  respect  to
deferred tax assets, useful lives associated with property and equipment and finite lived intangible assets, and the valuation and
assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, the Company evaluates its
estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of
assets  and  liabilities.  In  addition,  the  Company  engages  the  assistance  of  valuation  specialists  in  concluding  on  fair  value
measurements in connection with stock-based compensation and other equity instruments.

(b)
Liquidity

Since inception, the Company has incurred net losses. During the years ended December 31, 2015, 2014, and 2013 the
Company incurred net losses of $41,230 ,   $5,811 , and $19,125 , respectively. The Company used $18,184 of cash in operations
for the year ended December 31, 2015, provided $450 cash from operations during the year ended December 31, 2014 and used
$25,877 of cash in operations during the year ended December 31, 2013. At December 31, 2015 and 2014 the Company had an
accumulated deficit of $175,276 and $134,046 , respectively. At December 31, 2015, the Company had cash and cash equivalents
of $112,801 .   The accompanying financial statements have been prepared on a going concern basis, which implies the Company
will  continue  to  realize  its  assets  and  discharge  its  liabilities  in  the  normal  course  of  business.  Silimed  is  the  Company’s  sole
source manufacturer of silicone gel breast implants, tissue expanders and other products. The continuation of the Company as a
going  concern  is  dependent  upon  many  factors  including  the  satisfactory  resolution  of  the  regulatory  inquiries  of  Silimed’s
medical devices, Silimed’s ability to resume the manufacturing of the Company’s medical devices, the availability of alternative
manufacturing sources, and the resumption of the sale of the Company’s products. The Company’s ability to continue to meet its
obligations  and to achieve  its business objectives  is dependent upon, amongst other things, generating  sufficient  revenues. The
Company believes that it has the ability to continue as a going concern for at least 12 months. These financial statements do not
include  any  adjustments  to  the  recoverability  and  classification  of  recorded  asset  amounts  and  classification  of  liabilities  that
might be necessary should the Company be unable to continue as a going concern.

(c)
Cash
and
Cash
Equivalents

The  Company  considers  all  highly  liquid  investments  purchased  with  an  original  maturity  of  three  months  or  less  to  be  cash
equivalents. Cash equivalents consist primarily of checking accounts.

(d)
Concentration
of
Credit
and
Supplier
Risks

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily
of  cash  and  cash  equivalents.  The  Company’s  cash  and  cash  equivalents  are  deposited  in  demand  accounts  at  a  financial
institution  that  management  believes  is  creditworthy.  The  Company  is  exposed  to  credit  risk  in  the  event  of  default  by  this
financial institution for cash and cash equivalents in excess of amounts insured by the Federal Deposit Insurance Corporation, or
FDIC.  Management  believes  that  the  Company’s  investments  in  cash  and  cash  equivalents  are  financially  sound  and  have
minimal credit risk and the Company has not experienced any losses on its deposits of cash and cash equivalents.

The Company currently purchases all of its Breast Products from one supplier under an exclusivity contract. The supplier and its
production facility are located in Brazil. The Company is exposed to risks of foreign regulations in Brazil that could hinder the
Company’s ability to import goods, as well as halts or limitations in productions due to events outside of the Company’s control
occurring  at  the  production  facility.  This  could  result  in  the  Company  not  being  able  to  acquire  the  inventory  needed  to  meet
customer demand, which would result in possible loss of sales and affect operating results adversely.

Table of Contents

Several  recent  events  have occurred  which have  affected  the  Company’s  ability  to rely  on Silimed  as their  source  for
silicone gel breast implants, tissue expanders and other products in the short and long term, including the suspension of Silimed’s
CE  certificate  by  TUV  SUD,  Silimed’s  notified  body  under  EU  regulation,  relating  to  particles  on  Silimed  breast  products,
followed  by  Brazilian  regulatory  inquiries  and  a  temporary  suspension  by  the  Brazilian  regulatory  agency  ANVISA  and  the
Department  of  the  Secretary  of  State  of  Rio  de  Janeiro  of  the  manufacturing  and  shipment  of  all  medical  devices  made  by
Silimed, including products manufactured for Sientra. As a result of this suspension, between October 9, 2015 and March 1, 2016,
the Company voluntarily placed a temporary hold on the sale of all Sientra devices manufactured by Silimed and recommended
that plastic surgeons discontinue implanting the devices. As of March 1, 2016, after ongoing discussions with the FDA and the
Company’s own review of the matter with the assistance of independent experts in quality management systems, GMP and data-
based risk assessment, the Company lifted the temporary hold on sales and also sent a letter to plastic surgeons informing them of
the Company’s market re-entry plans.

In addition, on October 22, 2015, there was a fire in the manufacturing building where Silimed primarily manufactures
Sientra’s  breast  implants.  The  Company  is  working  with  Silimed  to  seek  clarity  as  to  the  near  and  long-term  capabilities  of
Silimed’s  manufacturing  operations,  including  the  status  of  equipment  that  is  used  to  manufacture  breast  implants  and  the
potential feasibility, production capacity and timing related to Silimed’s ability to manufacture the Company’s breast implants.

  (e)
Fair
Value
of
Financial
Instruments

The  carrying  amounts  of  cash  and  cash  equivalents,  accounts  receivable,  accounts  payable,  accrued  liabilities,  and  customer
deposits are reasonable estimates of their fair value because of the short maturity of these items. The fair value of the common
stock warrant liability is discussed in Note 2(f).  As of December 31, 2015, the Company had no outstanding long-term debt.

(f)
Fair
Value
Measurements

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would
be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or
liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair
value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities
carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the
first two are considered observable and the last is considered unobservable:

·

·

·

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

Level  2  —  Observable  inputs  (other  than  Level  1  quoted  prices)  such  as  quoted  prices  in  active  markets  for  similar
assets  or  liabilities,  quoted  prices  in  markets  that  are  not  active  for  identical  or  similar  assets  or  liabilities,  or  other
inputs that are observable or can be corroborated by observable market data.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to determining
the  fair  value  of  the  assets  or  liabilities,  including  pricing  models,  discounted  cash  flow  methodologies  and  similar
techniques.

The  Company’s  common  stock  warrant  liabilities  are  carried  at  fair  value  determined  according  to  the  fair  value
hierarchy  described  above.  The  Company  has  utilized  an  option  pricing  valuation  model  to  determine  the  fair  value  of  its
outstanding  common  stock  warrant  liabilities.  The  inputs  to  the  model  include  fair  value  of  the  common  stock  related  to  the
warrant, exercise price of the warrant, expected term, expected volatility, risk-free interest rate and dividend yield. Prior to the
IPO,  the  Company  determined  the  fair  value  per  share  of  the  underlying  common  stock  by  taking  into  consideration  its  most
recent sale of its convertible preferred stock as well as additional factors that the Company deems relevant.  Subsequent to the
IPO, the warrants are valued using the fair value of common stock as of the measurement  date. The Company historically  has
been  a  private  company  and  lacks  company-specific  historical  and  implied  volatility  information  of  its  stock.  Therefore,  it
estimates its expected stock volatility based on the historical volatility of publicly traded peer companies for a term equal to the
remaining contractual term of the warrants. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve
for  time  periods  approximately  equal  to  the  remaining  contractual  term  of  the  warrants.  The  Company  has  estimated  a  0%
dividend yield based on the expected dividend yield and the fact

80

 
Table of Contents

that  the  Company  has  never  paid  or  declared  dividends.  As several  significant  inputs  are  not  observable,  the  overall  fair  value
measurement of the warrants is classified as Level 3.

The following tables present information about the Company’s liabilities that are measured at fair value on a recurring

basis as of December 31, 2015 and 2014 and indicate the level of the fair value hierarchy utilized to determine such fair value:

The company recognized changes in the fair value of these warrants in other (expense) income, net in the statement of

operations.

(g)
Property
and
Equipment

Property  and  equipment  are  stated  at  cost,  net  of  accumulated  depreciation.  Depreciation  is  computed  using  the  straight  ‑line
method over the estimated useful life of the asset; generally three years. Leasehold improvements are depreciated over the shorter
of  the  lease  term  or  the  estimated  useful  life  of  the  related  asset.  Upon  retirement  or  sale  of  an  asset,  the  cost  and  related
accumulated  depreciation  or  amortization  are  removed  from  the  balance  sheet  and  any  resulting  gain  or  loss  is  reflected  in
operations in the period realized. Maintenance and repairs are charged to operations as incurred.

(h)
Goodwill
and
Other
Intangible
Assets

Goodwill represents the excess of the purchase price over the fair value of net assets of purchased businesses. Goodwill
is  not  amortized,  but  instead  subject  to  impairment  tests  on  at  least  an  annual  basis  and  whenever  circumstances  suggest  that
goodwill  may  be  impaired.  The  Company’s  annual  test  for  impairment  is  performed  as  of  October  1  of  each  fiscal  year.  The
Company  makes  a  qualitative  assessment  of  whether  it  is  more  likely  than  not  that  a  reporting  unit’s  fair  value  is  less  than  its
carrying amount before applying the two ‑step goodwill impairment test. If the Company concludes that it is not more likely than
not that the fair value of a reporting unit is less than its carrying amount, it is not required to perform the two ‑step impairment
test for that reporting unit.

Under the first step of the test, the Company is required to compare the fair value of a reporting unit with its carrying
amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not
considered impaired and the second step of the test is not performed. If the results of the first step of the impairment test indicate
that the fair value of a reporting unit does not exceed its carrying amount, then the second step of the test is required. The second
step of the test compares the implied fair value of the reporting unit goodwill with the

carrying  amount of that goodwill. The impairment  loss is measured  by the excess of the carrying  amount of the reporting  unit
goodwill over the implied fair value of that goodwill.

Management  evaluates  the  Company  as  a  single  reporting  unit  for  business  and  operating  purposes  as  all  of  the
Company’s revenue streams are generated by the same underlying products via sales in the United States of America. In addition,
the  majority  of  the  Company’s  costs  are,  by  their  nature,  shared  costs  that  are  not  specifically  identifiable  to  a  geography  or
product line, but relate to all products. As a result, there is a high degree of interdependency among the Company’s net sales and
cash flows for the entity and identifiable cash flows for a reporting unit separate from the entity are not meaningful.

Judgments about the recoverability of purchased finite ‑lived intangible assets are made whenever events or changes in
circumstance indicate that impairment may exist. Each fiscal year the Company evaluates the estimated remaining useful lives of
purchased  intangible  assets  and  whether  events  or  changes  in  circumstance  warrant  a  revision  to  the  remaining  periods  of
amortization. Recoverability of finite ‑lived intangible assets is measured by comparison of the carrying amount of the asset to the
future undiscounted cash flows the asset is expected to generate. The intangible asset is amortized to the statement of operations
based on estimated cash flows generated from the intangible over its estimated life.

(i)
Impairment
of
Long
‑‑Lived
Assets

The  Company’s  management  routinely  considers  whether  indicators  of  impairment  of  long  ‑lived  assets  are  present.  If  such
indicators  are  present,  management  determines  whether  the  sum  of  the  estimated  undiscounted  cash  flows  attributable  to  the
assets in question is less than their carrying value. If less, the Company will recognize an impairment loss based on the excess of
the  carrying  amount  of  the  assets  over  their  respective  fair  values.  Fair  value  is  determined  by  discounted  future  cash  flows,
appraisals  or  other  methods.  If  the  assets  determined  to  be  impaired  are  to  be  held  and  used,  the  Company  will  recognize  an
impairment charge to the extent the present value of anticipated net cash flows attributable to the asset are less than the asset’s
carrying value. The fair value of the asset will then become the asset’s new carrying value. There have been no impairments of
long ‑lived assets recorded  during the years ended December 31, 2015, 2014 and 2013. The Company may record impairment
losses in future periods if factors influencing its estimates change.

(j)
Revenue
Recognition

The Company sells its product directly to customers in markets where it has regulatory approval. The Company offers a
six-month return policy and recognizes revenue net of sales discounts and returns in accordance with the Financial Accounting
Standards Board, or FASB, Accounting Standards Codification 605, Revenue Recognition, or ASC 605. ASC 605 requires that six
basic criteria must be met before revenue can be recognized when a right of return exists:

·

·

·

·

·

·

the seller’s price to the buyer is substantially fixed or determinable at the date of sale;

the  buyer  has  paid  the  seller,  or  the  buyer  is  obligated  to  pay  the  seller  and  the  obligation  is  not  contingent  on
resale of the product;

the buyer’s obligation to the seller would not be changed in the event of theft or physical destruction or damage of
the product;

the buyer acquiring the product for resale has economic substance apart from that provided by the seller;

the seller does not have significant obligations for future performance to directly bring about resale of the product
by the buyer; and

the amount of future returns can be reasonably estimated.

Appropriate reserves are established for anticipated sales returns based on historical experience, recent gross sales and
any  notification  of  pending  returns.  The  Company  recognizes  revenue  when  title  to  the  product  and  risk  of  loss  transfer  to
customers,  provided there  are no remaining  performance  obligations  required  of the Company or any written matters  requiring
customer acceptance. The Company allows for the return of product from customers within six months after the

Table of Contents

original  sale  and  records  estimated  sales  returns  as  a  reduction  of  sales  in  the  same  period  revenue  is  recognized.  Sales  return
provisions  are  calculated  based  upon  historical  experience  with  actual  returns.  Actual  sales  returns  in  any  future  period  are
inherently  uncertain  and  thus  may  differ  from  the  estimates.  If  actual  sales  returns  differ  significantly  from  the  estimates,  an
adjustment  to  revenue  in  the  current  or  subsequent  period  would  be  recorded.  The  Company  has  established  an  allowance  for
sales returns of $660 and $10,018 as of December 31, 2015 and 2014, respectively, recorded net against accounts receivable in
the balance sheet.

A portion of the Company’s revenue is generated from the sale of consigned inventory of breast implants maintained at
doctor,  hospital,  and  clinic  locations.  The  customer  is  contractually  obligated  to  maintain  a  specific  level  of  inventory  and  to
notify the Company upon use. For these products, revenue is recognized at the time the Company is notified by the customer that
the product has been implanted. Notification is usually through the replenishing of the inventory and the Company periodically
reviews  consignment  inventories  to  confirm  accuracy  of  customer  reporting.  FDA  regulations  require  tracking  the  sales  of  all
implanted breast implant products.

Shipping and handling charges are largely provided to customers free of charge. The associated costs are viewed as part
of  the  Company’s  marketing  programs  and  are  recorded  as  a  component  of  sales  and  marketing  expense  in  the  statement  of
operations. For the years ended 2015, 2014 and 2013 these costs amounted to $1,115 ,   $1,305 and $1,021 , respectively.

In other cases, shipping and handling charges may be invoiced to customers based on the amount of products sold. In
such cases, shipping and handling fees collected are recorded as revenue and the related expense as a component of cost of goods
sold.

(k)
Accounts
Receivable
and
Allowance
for
Doubtful
Accounts

Accounts  receivable  are  recorded  at  the  invoiced  amount  and  do  not  bear  interest.  The  Company  maintains  allowances  for
doubtful  accounts  for  estimated  losses  resulting  from  the  inability  to  collect  from  some  of  its  customers.  The  allowances  for
doubtful accounts are based on the analysis of historical bad debts, customer credit ‑worthiness, past transaction history with the
customer,  and  current  economic  trends.  If  the  financial  condition  of  the  Company’s  customers  were  to  deteriorate,  adversely
affecting their ability to make payments, additional allowances may be required. The Company has established an allowance for
doubtful accounts of $456 and $312 as of December 31, 2015 and 2014, respectively.

(l)
Inventories
and
Cost
of
Goods
Sold

Inventories  represent  finished  goods that  are  recorded  at the  lower of  cost or market  on a  first  ‑in, first ‑out basis, or
FIFO. The Company periodically assesses the recoverability of all inventories to determine whether adjustments for impairment
or  obsolescence  are  required.  The  Company  evaluates  the  remaining  shelf  life  and  other  general  obsolescence  and  impairment
criteria in assessing the recoverability of the Company’s inventory.

The  Company  recognizes  the  cost  of  inventory  transferred  to  the  customer  in  cost  of  goods  sold  when  revenue

is recognized.

At December 31, 2015 and 2014, approximately $2,274 and $1,989 , respectively, of the Company’s inventory was held

on consignment at doctors’ offices, clinics, and hospitals. The value and quantity at any one location is not significant.

(m)
Income
Taxes

The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and
liabilities  are  determined  based  on  the  difference  between  the  financial  statement  and  tax  bases  of  assets  and  liabilities  using
enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are
established when necessary to reduce deferred tax assets to the amounts expected to be realized.

The Company accounts for uncertain tax position in accordance with ASC 740 ‑10, Accounting for Uncertainty in Income Taxes .
The Company assesses all material positions taken in any income tax return, including all significant uncertain positions, in all tax
years that are still subject to assessment or challenge by relevant taxing authorities. Assessing

83

 
 
 
Table of Contents

an  uncertain  tax  position  begins  with  the  initial  determination  of  the  position’s  sustainability  and  is  measured  at  the  largest
amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. As of each balance sheet date,
unresolved  uncertain  tax  positions  must  be  reassessed,  and  the  Company  will  determine  whether  (i)  the  factors  underlying  the
sustainability  assertion have changed and (ii) the amount of the recognized tax benefit is still appropriate. The recognition and
measurement of tax benefits requires significant judgment. Judgments concerning the recognition and measurement of tax benefit
might change as new information becomes available.

(n)
Research
and
Development
Expenditures

Research and development costs are charged to operating expenses as incurred. Research and development, or R&D, primarily
consist  of  clinical  expenses,  regulatory  expenses,  product  development,  consulting  services,  outside  research  activities,  quality
control,  and  other  costs  associated  with  the  development  of  the  Company’s  products  and  compliance  with  Good  Clinical
Practices,  or  GCP,  requirements.  R&D  expenses  also  include  related  personnel  and  consultant  compensation  and  stock-based
compensation expense.

(o)
Advertising

Expenses related to advertising are charged to sales and marketing expense as incurred. Advertising costs were $1,029 ,   $1,548
and $801 for fiscal years 2015, 2014 and 2013, respectively.

(p)
Stock
‑‑Based
Compensation

The  Company  applies  the  fair  value  provisions  of  ASC  718,  Compensation  —  Stock  Compensation  ,  or  ASC  718.  ASC  718
requires the recognition of compensation expense, using a fair ‑value based method, for costs related to all employee share ‑based
payments, including stock options, restricted stock units,   and the employee stock purchase plan. ASC 718 requires companies to
estimate  the  fair  value  of  share  ‑based  payment  awards  on  the  date  of  grant  using  an  option  ‑pricing  model.  All option  grants
valued are being expensed on a straight ‑line basis over their vesting period.

The Black ‑Scholes model requires the input of subjective assumptions, including the risk ‑free interest rate, expected
dividend yield, expected volatility and expected term, among other inputs. These estimates involve inherent uncertainties and the
application  of  management’s  judgment.  If  factors  change  and  different  assumptions  are  used,  our  stock  ‑based compensation
expense could be materially different in the future. These assumptions are estimated as follows:

·

·

·

·

Risk ‑free interest rate —The risk ‑free interest rate is based on the yields of U.S. Treasury securities with maturities
similar to the expected term of the options for each option group.

Dividend yield —We have never declared or paid any cash dividends and do not presently plan to pay cash dividends in
the foreseeable future. Consequently, we used an expected dividend yield of zero.

Expected volatility —As we do not have a significant trading history for our common stock, the expected stock price
volatility  for  our  common  stock  was  estimated  by  taking  the  average  of  (i)  the  median  historic  price  volatility  and
(ii) the median of the implied volatility averages, with a three ‑month lookback from the valuation date, for any trading
options of industry peers based on daily price observations over a period equivalent to the expected term of the time to
a liquidity event. We intend to continue to consistently apply this process using the same or similar public companies
until  a  sufficient  amount  of  historical  information  regarding  the  volatility  of  our  own  common  stock  share  price
becomes available.

Expected term —The expected term represents the period that our stock ‑based awards are expected to be outstanding.

In  addition  to  the  assumptions  used  in  the  Black  ‑Scholes  option  pricing  model,  the  amount  of  stock  ‑based
compensation expense we recognize in our financial statements includes an estimate of stock option forfeitures. We estimate our
forfeiture rate based on an analysis of our actual forfeitures and will continue to evaluate the appropriateness of the forfeiture rate
based on actual forfeiture experience, analysis of employee turnover and other factors. Changes in the estimated forfeiture rate
can  have  a  significant  impact  on  our  stock  ‑based  compensation  expense  as  the  cumulative  effect  of  adjusting  the  rate  is
recognized  in  the  period  the  forfeiture  estimate  is  changed.  If  a  revised  forfeiture  rate  is  higher  than  the  previously  estimated
forfeiture rate, an adjustment is made that will result in a decrease to the stock ‑based compensation expense recognized in the
financial statements. If a revised forfeiture rate is lower than the previously estimated forfeiture rate, an adjustment is made that
will result in an increase to the stock ‑based compensation expense recognized in our financial statements.

The  Company  offers  a  limited  warranty  and  a  lifetime  product  replacement  program  for  the  Company’s  silicone  gel
breast implants. Under the limited warranty program, the Company will reimburse patients for certain out-of-pocket costs related
to  revision  surgeries  performed  within  ten years  from  the  date  of  implantation  in  a  covered  event.  Under  the  lifetime  product
replacement  program,  the  Company  provides  no-charge  replacement  breast  implants  under  a  covered  event.  The  programs  are
available to all patients implanted with the Company’s silicone breast implants after April 1, 2012 and are subject to the terms,
conditions, claim procedures, limitations and exclusions. Timely completion of a device tracking and warranty enrollment form
by the patient’s Plastic Surgeon is required to activate the programs and for the patient to be able to receive benefits under either
program.

Deferred
Equity
Issuance
Costs

Deferred equity issuance costs, primarily consisting of legal, accounting and other direct fees and costs relating to the IPO and
follow-on  offering,  were  capitalized,  as  incurred,  in  other  current  assets  prior  to  the  completion  of  the  IPO  and  follow-on
offering.   Upon completion  of the  IPO,  $3,178 of issuance costs were  capitalized,  all of which were reclassified  to additional-
paid-in capital to offset the IPO proceeds for the year ending December 31, 2014.  Upon completion of the follow-on offering,
$643 of issuance costs were capitalized, all of which were reclassified to additional-paid-in capital to offset the follow-on offering
proceeds for the year ended December 31, 2015.

Segment

Net
Loss
Per
Share

Basic loss per  share  attributable  to  common  stockholders  is  computed  by  dividing  net  loss  by  the  weighted  average
number  of  common  shares  outstanding  during  each  period.  Diluted  loss  per  common  share  is  computed  by  dividing  net  loss
available  to  common  stockholders  by  the  weighted  average  number  of  common  shares  and  dilutive  potential  common  share
equivalents then outstanding, to the extent they are dilutive. Potential common shares consist of shares issuable upon the exercise
of stock options and warrants (using the treasury stock method), and the weighted average conversion of the convertible preferred
stock into shares of common stock (using the if-converted method). Dilutive loss per share is the same as basic loss per share for
all periods presented because the effects of potentially dilutive items were anti-dilutive.

In May 2014, the FASB, issued accounting standard update, or ASU, 2014-09, Revenue from Contracts with Customers,
or Topic 606 .  The standard was issued to provide a single framework that replaces existing industry and transaction specific U.S.
GAAP  with  a  five  step  analysis  of  transactions  to  determine  when  and  how  revenue  is  recognized.    The  accounting  standard
update will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective.  In August 2015, the
FASB issued  ASU 2015-14,  Revenue  from Contracts  with  Customers (Topic  606):  Deferral  of  the  Effective  Date,  to defer the
effective date of ASU 2014-09 by one year.  Therefore, ASU 2014-09 will become effective for the Company beginning in fiscal
year 2018. Early adoption would be permitted for the Company beginning in fiscal year 2017. The standard permits the use of
either  the  retrospective  or  cumulative  transition  method.  The  Company  is  currently  evaluating  the  accounting,  transition  and
disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.

In April 2015, the FASB issued accounting standard update 2015-03 , Interest — Imputation of Interest .  The standard
was issued to  simplify  the  presentation  of debt  issuance  costs  and  require  that  debt issuance  costs  related  to  a recognized  debt
liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt
discounts.    This  accounting  standard  update  will  be  effective  for  the  Company  beginning  in  fiscal  year  2016.    The  Company
anticipates there will be no material impact on its financial statement upon adoption of this guidance.

In April 2015, the FASB issued accounting standard update 2015-05 , Intangibles — Goodwill and Other — Internal-
Use Software .  The standard was issued to provide guidance to customers about whether a cloud computing arrangement includes
a  software  license.    If  a  cloud  computing  arrangement  includes  a  software  license,  then  the  customer  should  account  for  the
software  license  element  of  the  arrangement  consistent  with  the  acquisition  of  other  software  licenses.    If  a  cloud  computing
arrangement  does  not  include  a  software  license,  the  customer  should  account  for  the  arrangement  as  a  service  contract.    This
accounting standard update will be effective for the Company beginning in fiscal year 2016.  The Company anticipates there will
be no material impact on its financial statement upon adoption of this guidance.

In  July  2015,  the  FASB  issued  accounting  standard  update  2015-11  ,  Inventory  —  Simplifying  the  Measurement  of
Inventory .  The standard simplifies the subsequent measurement of inventory by requiring inventory to be measured at the lower
of cost and net realizable value, thereby simplifying the current guidance under which an entity must measure inventory at the
lower of cost or market. The accounting standards update will not apply to inventories that are measured by using either the last-
in, first-out method or the retail inventory method. This accounting standard update will be effective for the Company beginning
in fiscal  year 2017. The Company anticipates  there will be no material  impact  on its financial  statement  upon adoption of this
guidance.

In  November  2015,  the  FASB  issued  accounting  standard  update  2015-17,  Income  Taxes  –  Balance  Sheet  Classification  of
Deferred Taxes. The standard simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities
be classified as noncurrent in a classified statement of financial position. Current GAAP requires an entity to separate deferred
income tax liabilities and assets into current and noncurrent amounts. This accounting standard update will be effective for the
Company beginning in fiscal year 2017. The Company anticipates there will be no material impact to its financial statement upon
adoption of this guidance.

In February 2016, the FASB issued accounting standard update 2016-02, Leases (Topic 842) which supersedes FASB Accounting
Standard  Codification  Leases  (Topic  840).  The  standard  is  intended  to  increase  the  transparency  and  comparability  among
organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing
arrangements. This accounting standard update will be effective for the Company beginning in fiscal year 2019. The Company is
currently evaluating the impact that adoption of the standard will have on the financial statements and related disclosures.

On January 17, 2013, the Company entered into a Loan and Security Agreement, or the Original Term Loan Agreement,
with Oxford providing for a $15,000 term loan facility consisting of original term loans of (i) a $7,500 tranche A term loan, (ii) a
$2,500 tranche  B  term  loan  and  (iii)  a  $5,000 tranche  C  term  loan,  maturing  on  February  1,  2017.    The  term  loan  facility  is
collateralized  by  a  first-priority  security  interest  in  substantially  all  of  the  Company’s  assets.    Borrowings  under  the  term  loan
facility  bear  interest  at  a  rate  equal  to  8.4%  per  annum  and  the  Original  Term  Loan  Agreement  provides  for  interest-only
payments through June 30, 2015.  The term loans include an additional lump sum payment of $975 due on February 1, 2017.

On June 30, 2014, the Company entered into the Amended and Restated Loan and Security Agreement, or the Amended
Term Loan Agreement, with Oxford, under which the interest-only period for the original term loans was extended to August 1,
2015  and  raised  an  additional  $10,000  in  a  fourth  tranche  (tranche  D)  maturing  on  January  1,  2019.  The  term  loans  are
collateralized by a first-priority security interest in substantially all of the Company’s assets. The term loans bear interest at a rate
equal to 8.4% per annum. The interest-only period for the tranche A, B and C term loans ends on August 1, 2015 and the interest-
only period for the tranche D term loan ends on the same date, but was extended another year to August 1, 2016 as the Company
raised at least $50,000 in gross proceeds as part of the IPO (see Note 1). The tranche D term loan includes an additional lump sum
payment of $650 due on January 1, 2019.

The Amended Term Loan Agreement contains various negative and affirmative covenants, including certain restrictive
covenants that limit the Company’s ability to transfer or dispose of certain assets, engage in new lines of business, change the
composition  of  Company  management,  merge  with  or  acquire  other  companies,  incur  additional  debt,  create  new  liens  and
encumbrances,  pay  dividends  or  subordinated  debt  and  enter  into  material  transactions  with  affiliates,  among  others.  The
Amended Term Loan Agreement also contains financial reporting requirements.

In connection with the Original Term Loan Agreement and the Amended Term Loan Agreement, the Company issued to
Oxford (i)  seven -year warrants in Jan uary 2013 to purchase shares of the Company’s common stock with a value equal to 3.0%
of the tranche A, B   and C   term loans amounts and (ii)  seven -year warrants in June 2014 to purchase shares of the Company’s
common stock with a value equal to 2.5% of the tranche D term loan amount.  The warrants have an exercise price per share of
$14.671 .

On October 27, 2015, Oxford issued a notice to Sientra indicating that, in connection with the recent events involving
Silimed  and  the  Company,  certain  events  of  default  have  occurred  and  continue  to  exist  under  the  Amended  Term  Loan
Agreement. On October 28, 2015, Sientra repaid all principal, interest, other amounts and obligations owed to Oxford under the
term loans for a total of $24 ,539 , following which the Company has no outstanding debt obligations.

(5) Goodwill

The Company evaluates goodwill for impairment at least annually on October 1  and whenever circumstances suggest

st 

that goodwill may be impaired.

On September 24, 2015, the Company experienced a significant decline in its common stock price, which was sustained
through September 30, 2015. The significant decline in the Company’s common stock price for a sustained period, along with the
impact from regulatory inquiries related to medical devices manufactured by Silimed, the Company’s contract manufacturer, were
identified as potential indicators of impairment of goodwill and other intangibles. As a result, the Company was required to assess
whether or not an impairment of its goodwill had occurred as of Septembe r 30, 2015.  The Company assessed the impact of the
recent  downward  volatility  in  the  Company's  common  stock  price  and  concluded  that  the  sustained  decline  constituted  a
triggering event requiring an interim goodwill impairment test. The Company conducted the first step of the goodwill impairment
test  described  above  for  its single  reporting  unit  as  of  September  30,  2015.  The  fair  value  of  the  reporting  unit  exceeded  its
carrying value as of September 30, 2015 by 24.7% , and therefore goodwill was determined to not be impaired as of September
30, 2015.

As  a  result  of  the  actions  taken  by  the  Brazilian  regulatory  agency  ANVISA  on  October  2,  2015,  and  the  Company
voluntarily  placing  a  hold  on  the  sale  of  all  Sientra  devices  manufactured  by  Silimed  on  October  9,  2015,  the  Company
experienced  a  significant  decline  in its common  stock price,  which was sustained  through December  31, 2015. The significant
decline  in  the  Company’s  common  stock  price  for  a  sustained  period,  along  with  the  impact  from  recent  regulatory  inquiries
related to medical devices manufactured by Silimed, the Company’s contract manufacturer, were identified as potential indicators
of  impairment  of  goodw  ill  and  the  Company  concluded  that  the  se  events  constituted  a  triggering  event  requiring  a  goodwill
impairment test. The Company conducted a step one analysis which consists of a comparison of the fair value of the Company as
a  single  reporting  unit  using  a  market  approach  against  its  carrying  amount,  including  goodwill.    As  a  result  of  the  step  one
analysis, it was determined that the carrying value exceeded its fair value; therefore the Company proceeded to step two of the
goodwill impairment analysis. For step two, the Company compared the implied fair value of goodwill with the carrying amount
of goodwill and based on the analysis, there was no implied goodwill; therefore the Company recorded a goodwill impairment
charge of   $14,278 for the quarter ended December 31, 2015 .

The  Company  has  established  a  full  valuation  allowance  against  its  net  deferred  tax  assets  due  to  the  uncertainty

surrounding realization of such assets.

As of December 31, 2015 , the Company had net operating loss carryforwards of approximately $137,832 and $120,056
available  to  reduce  future  taxable  income,  if  any,  for  federal  and  state  income  tax  purposes,  respectively.  The  federal  net
operating loss carryforward begins expiring in 2027, and the state net operating loss carryforward s begin expiring in 2017. It is
possible that the Company will not generate taxable income in time to use these NOLs before their expiration. In addition, under
Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, if a corporation undergoes an “ownership change ”, t
he  corporation's  ability  to  use  its  pre-change  NOL  carryforwards  and  other  pre-change  tax  attributes  to  offset  its  post-change
income  may  be  limited.      In  general,  an  “ownership  change”  occurs  if  there  is  a  cumulative  change  in  a  loss  corporation’s
ownership  by  5%  shareholders  that  exceeds  50  percentage  points  over  a  rolling  three-year  period.    The  Company  has  not
performed a detailed analysis to determine whether an ownership change under Section 382 of the Code has previously occurred.
As a result, if the Company earn s net taxable income, its ability to use   their pre-change   net operating loss carryforwards to
offset  U.S.  federal  taxable  income  may  become  subject  to  limitations,  which  could  potentially  result  in  increased  future  tax
liability to the Company . Until such analysis is completed, the Company cannot be sure that the full amount of the existing fede
ral NOLs will be available to them, even if taxable income is generated before their expiration.

As of December 31, 2015 , the Company had research and development credit carryforwards of approximately $1,804
and $1,762 available to reduce future taxable income, if any, for federal and California state income tax purposes, r espectively.
The federal credit carryforwards begin expiring in 2027 and the state credits carryforward indefinitely.

At December 31, 2015 , the Company had unrecognized tax benefits of approximately $732 associated with the research
and development credits. The Company does not anticipate that total unrecognized net tax benefits will significantly change over
the next twelve months.

It is the  Company’s  policy  to  include  penalties  and  interest  expense  related  to  income  taxes  as  a  component  of  other
expense and interest expense, respectively, as necessary. There was no interest expense or penalties related to unrecognized tax
benefits recorded through December 31, 2015 .

The  Company  files  U.S.  federal  and  state  income  tax  returns  in  jurisdictions  with  varying  statute  of  limitations.  The
years that may be subject to examination will vary by jurisdicti on. The Company’s tax years 201 1 to 201 5 will remain open for
examination by the federal and state tax authorities.

( 7 )   Stockholders’ Equity

(a)

Authorized
Stock

The  Company’s  Amended  and  Restated  Certificate  of  Incorporation,  effective  upon  the  completion  of  the  IPO,
authorizes  the  Company  to  issue  210,000,000  shares  of  common  and  preferred  stock,  consisting  of  200,000,000  shares  of
common stock with $0.01 par value and 10,000,000 shares of preferred stock with $0.01 par value. As of December 31, 2015 , the
Company has no preferred stock issued or outstanding .

(b)

Stock
Options

In  April  2007,  the Company  adopted  the  2007  Equity  Incentive  Plan,  or  2007  Plan.  The  2007  Plan  provides  for  the
granting  of  stock  options  to  employees,  directors  and  consultants  of  the  Company.  Options  granted  under  the  2007  Plan  may
either  be  incentive  stock  options  or  nonstatutory  stock  options.  Incentive  stock  options,  or  ISO  s,  may  be  granted  only  to
Company employees.

Nonstatutory  stock  options,  or  NSO  s,  may  be  granted  to  all  eligible  recipients.  A  total  of  1,690,448  shares  of  the

Company’s common stock were reserved for issuance for the 2007 Plan.

As  of  December  31,  2015,  pursuant  to  the  2007  Plan,  there  were  1,605,537 shares  of  common  stock  reserved  and  no

shares of common stock available for future grants.

The  Company’s  board  of  directors  adopted  the  2014  Equity  Incentive  Plan,  or  2014  Plan,  in  July  2014,  and  the
stockholders  approved  the  2014  Plan  in  October  2014. The  2014  Plan  became  effective  upon completion  of  the  IPO, at  which
time the Company ceased making awards under the 2007 Plan. Under the 2014 Plan, the Company may issue ISO, NSOs, stock
appreciation rights, restricted stock awards, restricted stock unit awards and other forms of stock awards, or collectively, stock
awards, all of which may be granted to employees, including officers, non-employee directors and consultants of the Company
and their affiliates. ISOs may be granted only to employees.  A total of 1,027,500 shares of common stock were initially reserved
for issuance under the 2014 Plan, subject to certain annual increases.  

Options  under  the  2007  Plan  and  the  2014  Plan  may be  granted  for  periods  of  up  to  ten years  as  determined  by  the
Company’s  board  of  directors,  provided,  however,  that  (i)  the  exercise  price  of  an  ISO  shall  not  be  less  than  100%  of  the
estimated  fair  value  of  the  shares  on  the  date  of  grant,  and  (ii)  the  exercise  price  of  an  ISO  granted  to  a  more  than  10%
shareholder  shall  not  be  less  than  110% of  the  estimated  fair  value  of  the  shares  on  the  date  of  grant.  An  NSO  has  no  such
exercise  price  limitations.  The  options  generally  vest  with  25%  of  the  grant  vesting  on  the  first  anniversary  and  the  balance
vesting monthly on a straight-lined basis over the requisite service period of three additional years for the award.  Additionally,
options  have  been  granted  to  certain  key  executives  which  vest  upon  achievement  of  performance  conditions  based  on
performance targets as defined by the board of directors, which have included net sales targets and defined corporate objectives
over the performance  period with possible  payouts ranging  from  0% to 100% of the  target  award  .   Compensation expense is
recognized on a straight-lined basis over the vesting term of one year based upon the probable

performance target that will be met.  The vesting provisions of individual options may vary but provide for vesting of at least 25%
per year.

As of December 31, 2015 , pursuant to the 2014 Plan, there were 1,325,759 shares of common stock reserved and 71,388

The weighted average grant date fair value of stock options granted to employees and directors during the years ended
December 31, 2015 and 2014 , and 2013   was $4.60 ,   $6.82 , and $1.90   per share, respectively. Stock-based compensation
expense for stock options for the years ended December 31, 2015 ,   2014 and 2013 was $2,005 ,   $560 and $342 , respectively.
Tax benefits arising from the disposition of certain shares issued upon exercise of stock options within two years of the date of
grant or within one year of the date of exercise by the option holder, or Disqualifying Dispositions, provide the Company with a
tax deduction equal to the difference between the exercise price and the fair market value of the stock on the date of exercise.
When realized, those excess windfall tax benefits are credited to additional paid-in capital. As of December 31, 2015 there was  
$4,733 of total unrecognized compensation cost related to stock options granted under the plans .   The costs are expected to be
recognized over a weighted average period of 2.95 years.   The expense is recorded within the operating expense components in
the statement of operations based on the employees receiving the awards.

The  aggregate  intrinsic  value  of  stock  options  is  calculated  as  the  difference  between  the  exercise  price  of  the  stock
options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair
value  of  the  Company’s  common  stock.  The  aggregate  intrinsic  value  of  stock  options  exercised  was  $597 ,   $176 , and $1  
during the years ended December 31, 2015 ,   2014   and 2013 ,   respectively .

The  expected  term  of  employee  stock  options,  risk  ‑free  interest  rate  and  volatility  represents  the  weighted  average,  based  on
grant date period, which the stock options are expected to remain outstanding. The Company utilized the simplified method to
estimate  the expected  term of the options pursuant to ASC Subtopic 718 ‑10 for all option grants to employees.  The expected
volatility  is  based  upon  historical  volatilities  of  an  index  of  a  peer  group  because  it  is  not  practicable  to  make  a  reasonable
estimate of the Company’s volatility. The risk ‑free interest rate is based on the U.S. Treasury yield curve in effect at the time of
the  grant  for  periods  corresponding  with  the  expected  term  of  the  option.  The  dividend  yield  assumption  is  based  on  the
Company’s  history  and  expectation  of  dividend  payouts.  The  Company  has  never  declared  or  paid  any  cash  dividends  on  its
common stock, and the Company does not anticipate paying any cash dividends in the foreseeable future.

As  stock  ‑based  compensation  expense  recognized  in  the  Company’s  statement  of  operations  is  based  on  awards
ultimately  expected  to  vest,  the  amount  has  been  reduced  for  estimated  forfeitures.  Forfeitures  were  estimated  based  on  the
Company’s historical experience and future expectations.

For purposes of financial accounting for stock ‑based compensation, the Company has determined the fair values of its
options  based  in  part  on  the  work  of  a  third  ‑party  valuation  specialist.  The  determination  of  stock  ‑based  compensation  is
inherently uncertain and subjective and involves the application of valuation models and assumptions requiring the use

of judgment. If the Company had made different assumptions, its stock ‑based compensation expense, and its net loss could have
been significantly different.

Restricted
Stock
Units

The Company issued restricted stock units, or RSUs, under the 2014 Plan, during the year ending December 31, 2015. The
restricted stock units issued vest monthly, on a   straight-line basis, over a 4 year requisite service period.

was $2 .   As of December 31, 2015, there was $67 of total unrecognized compensation cost related to non-vested RSU awards.
The cost is expected to be recognized over a weighted average period of 3.87 years.

Employee
Stock
Purchase
Plan

The  Company’s  board  of  directors  adopted  the  2014  Employee  Stock  Purchase  Plan,  or  ESPP,  in  July  2014,  and  the
stockholders  approved  the  ESPP  in  October  2014.  The  ESPP  allows  eligible  employees  to  purchase  shares  of  the  Company’s
common  stock  at  a  discount  through  payroll  deductions  of  up  to  15%  of  their  eligible  compensation,  subject  to  any  plan
limitations. The ESPP provides offering periods not to exceed 27 months , and each offering period will include purchase periods,
which will be the approximately six -month period commencing with one exercise date and ending with the next exercise date,
except that the first offering period commenced on the first trading day following the effective date of the Company's registration
statement.  Employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock
on the first trading day of the offering period or on the exercise date.  The number of shares available for sale under the 2014
Employee Stock Purchase Plan will be increased annually on the first day of each fiscal year, equal to the lesser of i) 1% of the
total outstanding shares of the Company’s common stock as of the last day of the immediately preceding fiscal year; ii) 3,000,000
shares of common stock, or iii) such lesser amount as determined by the board of directors.

As of December 31, 2015, the number of shares of common stock reserved for issuance under the ESPP was 404,629 .  
During  the  year  ended  December  31, 2015  ,  employees  purchased  44,250 shares  under  the  2014  ESPP  at  a  weighted  average
exercise  price  of  $12.75      per  share.  As  of  December  31,  2015,  the  number  of  shares  of  common  stock  available  for  future
issuance under the ESPP was   360,379 . Stock -based compensation related to the ESPP for the years ended December 31, 2015
and 2014 was $375 and $34 , respectively.

(c)

Contingencies

The Company is subject to claims and assessments from time to time in the ordinary course of business. The Company
accrues  a  liability  for  such  matters  when  it  is  probable  that  future  expenditures  will  be  made  and  such  expenditures  can  be
reasonably estimated. There were no contingent liabilities requiring accrual as of December 31, 2015 .  

In 2012, the Company filed a claim with the Hartford Insurance Company, or Hartford for reimbursement of legal costs
incurred in connection with litigation with a competitor that was resolved in 2013. The Company held a D&O insurance policy
with Hartford, and the Company and Hartford settled the matter in May 2014. The Company received settlement payments from
Hartford and recovery of costs associated with the litigation of $0 ,   $2,358 , and $351   for the years ended December 31, 2015,
2014 and 2013, respectively.

On September 25, 2015, a lawsuit styled as a class action of the Company’s stockholders was filed in the United States
District Court for the Central District of California. The lawsuit names the Company and certain of its officers as defendants and
alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, or the

Exchange Act, in connection with allegedly false and misleading statements concerning the Company’s business, operations, and
prospects.  The plaintiff seeks damages and an award of reasonable costs and expenses, including attorneys’ fees.   On November
24, 2015, three stockholders (or groups of stockholders) filed motions to appoint lead plainti ff(s) and to approve their selection
on lead counsel.  On December 10, 2015, the court entered an order appointing lead plaintiffs and approving their se lection of
lead counsel.  On February 19, 2016, lead plaintiffs filed their consolidated amended complaint.

On  October    28  ,  November  5,  and  November  19,  2015,  three  lawsuits  styled  as  class  actions  of  the  Company’s
stockholders  were  filed  in  the  Superior  Court  of  California  for  the  County  of  San  Mateo.  The  lawsuits  name  the  Company  ,
certain of its officers and directors, and the underwriters associated with the Company’s follow-on public offering that closed on
September  23,  2015  as  defendants.  The  lawsuits  allege  violations  of  Sections  11,  12(a)(2),  and  15  of  the  Securities  Act  in
connection with allegedly false and misleading statements in the Company’s offering documents associated with the follow-on
offering  concerning  its business,  operations,  and  prospects.  The  plaintiffs  seek  damages  and  an  award  of  reasonable  costs  and
expenses, including attorneys’  fees. On  December  4,  2015,  defendants  removed  all  three lawsuits  to  the  United  States  District
Court for the Northern District of California.  On December 15 and December 16, 2015, plaintiffs filed motions to remand the
lawsuits back to San Mateo Superior Court , or the Motions to Remand.  On January 19, 2016, defendants filed their opposition to
the Motions to Remand, and plaintiffs filed their reply in support of the Motions to Remand on January 26, 2016.

It is possible that additional suits will be filed, or allegations made by stockholders, with respect to these same or other
matters and also naming the Company and/or its officers and directors as defendants. The Company believes it has meritorious
defenses and intends to defend these lawsuits vigorously.  Due to the early stage of these proceedings,   the Company is not able
to predict or reasonably estimate the ultimate outcome or possible losses relating to these claims.

Surgeons informing them of the Company’s market re-entry plans. The conclusive results of our testing indicate no anticipated
significant safety concerns with the use of our products, including our breast implants, consistent with their approval status since
2012.

sition
of
bioCorneum

On March 9, 2016, pursuant to the Asset Purchase Agreement, or the Purchase Agreement, by and among the Company,
Enaltus, LLC, and HealthEdge Investment Fund, L.P, we acquired certain assets of bioCorneum, an advanced silicone gel scar
management  therapy  product for the purchase  price of $7,000 in cash.  The assets acquired consist of inventory, intellectual  p
roperty, specified contracts and the associated assumed liabilities.

We expect to account for the transaction  as a business combination  and are in the process of determining the allocation of the
purchase price to acquired assets and assumed liabilities. A determination of the acquisition-date fair values of the assets acquired
and  the  liabilities  assumed  is  pending  the  completion  of  an  independent  appraisal  and  other  evaluations  and  therefore  further
disclosures have not been made .

provided that this Agreement becomes effective as specified in Section 1 1 below, the Company will
provide you with the following separation benefits (collectively, the “Separation Benefits”) ,   items

S alary .     (i) You shall receive aggregate payments equivalent to nine  ( 9 ) months

COBRA  coverage),  which  payments  shall  be  made  on  the  last  day  of  each  month  regardless  of
whether  you  elect  COBRA  continuation  coverage  and  shall  end  on  the  earlier  of  (x)  the  date  upon
which  you  obtain  other  employment  or  (y)  the  last  day  of  the  9  th  calendar  month  following  the

20. 

Counterparts.  This Agreement may be executed in two counterparts, each of which

shall be deemed an original, all of which together shall constitute one and the same instrument.

21. 

Section Headings.  The section and paragraph headings contained in this Agreement

are for reference purposes only and shall not affect in any way the meaning or interpretation of this
Agreement.

22. 

Photocopies.  A photocopy of this executed Agreement shall be as valid, binding, and

effective as the original Agreement.

23. 

Section 409A.  It is intended that all of the benefits and payments payable under this

Agreement satisfy, to the greatest extent possible, an exemption from Section 409A of the Internal
Revenue Code of 1986, as amended (“Section 409A”), and this Agreement will be construed to the
greatest extent possible as consistent with those exemptions, and to the extent not so exempt, this
Agreement (and any definitions hereunder) will be construed to the greatest extent possible in a
manner that complies with Section 409A. For purposes of Section 409A, your right to receive any
installment payments under this Agreement (whether severance payments, reimbursements or
otherwise) shall be treated as a right to receive a series of separate payments and, accordingly, each
installment payment hereunder shall at all times be considered a separate and distinct payment.
Notwithstanding any provision to the contrary in this Agreement, if you are deemed by the Company
at the time of your separation from service to be a “specified employee” for purposes of Section
409A, and if any of the payments upon separation from service set forth herein and/or under any
other agreement with the Company are deemed to be “deferred compensation”, then to the extent
delayed commencement of any portion of such payments is required in order to avoid a prohibited
distribution under Section 409A and the related adverse taxation under Section 409A, such payments
shall not be provided to you prior to the earliest of (i) the expiration of the six-month period
measured from the date of your separation from service, (ii) the date of your death or (iii) such earlier
date as permitted under Section 409A without the imposition of adverse taxation. If the release
revocation period spans two calendar years, payments will commence in the second of those two
calendar years to the extent required to comply with Section 409A.

 ”  (as  such  term  is  defined  in  NASDAQ  Listing  Rule  5605(a)(2)  )      or  the
Company’s compensation committee, provided such committee is comp rised solely of Independent
Directors (the “ Independent

2. 

Administration.

(a)

that  Stock  Awards  may  only  be  granted  by  either  (i)  a  majority  of  the  Company's  Independent
Directors or (ii) the Independent  Compensation  Committee  .   Subject  to  those  constraints  and  the

administration of the Plan to a Committee, as provided in Section 2 (c).  

(b) 

Powers  of  Board.      The  Board  will  have  the  power,  subject  to,  and  within  the

To determine : (A )  who will be granted Stock Awards ; (B )  when and how
e  ach  Stock  Award  will  be  granted  ;  (C  )    what  type  of  Stock  Award  will  be  granted  ;  (D  )    the

establish, amend and revoke rules and regulations for administration of the Plan and Stock Awards .  
The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in the
Plan  or  in  any  Stock  Award  Agreement,  in  a  manner  and  to  the  extent  it  will  deem  necessary  or
expedient to make the Plan or Stock Award fully effective.

(iii) 

To settle all controversies regarding the Plan and Stock Awards granted under

it.

(iv) 

To accelerate, in whole or in part, the time at which a Stock Award may be

exercised or vest (or at which cash or shares of Common Stock may be issued).  

(v) 

To suspend or terminate the Plan at any time.   Except as otherwise provided
in the Plan or a Stock Award Agreement, suspension or termination  of the Plan will not materially
impair a Participant’s rights under his or her then-outstanding Stock Award without his or her written
consent except as provided in subsection (viii) below.

(vi) 

To  amend  the  Plan  in  any  respect  the  Board  deems  necessary  or  advisable,
including,  without  limitation,  adopting  amendments  relating  to  nonqualified  deferred  compensation
under  Section  409A  of  the  Code  and/or making the Plan or  Stock  Award  s granted under the Plan
exempt  from  or  compliant  with  the  requirements  for  nonqualified  deferred  compensation  under
Section  409A  of  the  Code  ,  subject  to  the  limitations,  if  any,  of  applicable  law.  I  f  required  by
applicable  law  or  listing  requirements  ,  and  except  as  provided  in  Section  9(a)  relating  to

under the Plan, (B) materially expands the class of individuals eligible to receive Stock Awards under
the Plan, (C) materially increases the benefits accruing to Participants under the Plan, (D )  materially
reduces  the  price  at  which  shares  of  Common  Stock  may  be  issued  or  purchased  under  the  Plan,
(E)  materially  extends  the  term  of  the  Plan,  or  (F)  materially  expands  the  types  of  Stock  Awards
available  for  issuance  under  the  Plan.      Except  as  otherwise  provided  in  the  Plan  (including
subsection  (viii)  below)  or  a  Stock  Award  Agreement,  no  amendment  of  the  Plan  will  materially
impair  a  Participant’s  rights  under  an  outstanding  Stock  Award  without  the  Participant’s  written
consent.  

(vii) 

To  submit  any  amendment  to  the  Plan  for  stockholder  approval,  including,

Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion .
  A   Participant’s rights under any Stock Award will not be impaired by any such amendment unless
the Company requests the consent of the affected Participant, and the Participant consents in writing.
  However, a Participant’s rights will not be deemed to have been impaired by any such amendment if
the Board, in its sole discretion, determines that the amendment, taken as a whole, does not materially
impair the Participant’s rights .   In addition, subject to the limitations of applicable law, if any, the
Board  may  amend  the  terms  of  any  one  or  more  Stock  Awards  without  the  a  ffected Participant’s
consent ( A ) to clarify the manner of exemption from, or to bring the Stock Award int o compliance

shares of Common Stock as the cancelled Stock Award and (y )  granted under the Plan or another
equity or c ompensatory plan of the Company ; or (C )  any other action that is treated as a repricing
under generally accepted accounting principles.

(c) 

Delegation to Committee.  

(i) 

General.   The Board may delegate some or all of the administration of the
Plan to a Committee or Committees.   If administration of the Plan is delegated to a Committee, the
Committee  will  have,  in  connection  with  the  administration  of  the  Plan,  the  powers  theretofore
possessed by the Board that have been delegated to the Committee, including the power to delegate
to a subcommittee of the Committee any of the administrative powers the Committee is authorized to
exercise  (and  references  in  this  Plan  to  the  Board  will  thereafter  be  to  the  Committee  or
subcommittee).      Any  delegation  of  administrative  powers  will  be  reflected  in  resolutions,  not
inconsistent with the provisions of the Plan, adopted from time to time by the Board or Committee
(as  applicable).      The  Committee  may,  at  any  time,  abolish  the  subcommittee  and/or  revest  in  the
Committee any powers delegated to the subcommittee.   The Board may retain the authority to

3 .

 
concurrently administer the Plan with the Committee and may, at any time, revest in the Board some
or all of the powers previously delegated.

(ii) 

Rule 16b-3 Compliance.   The Committee may consist solely of two or more

Non-Employee Directors, in accordance with Rule 16b-3 of the Exchange Act .

(d) 

Effect  of  Board’s  Decision.  All  determinations,  interpretations  and  constructions
made by the Board in good faith will not be subject to review by any person and will be final, binding
and conclusive on all persons.

3. 

Shares Subject to the Plan.

(a) 

Share Reserve .  

(i) 

Subject to Section 9(a) relating to Capitalization Adjustments, the aggregate
number  of  shares  of  Common  Stock  that  may  be  issued  pursuant  to  Stock  Awards  will  not  exceed
180,000 shares (the “ Share
Reserve
”) .    

(ii) 

For  clarity,  the  Share  Reserve  is  a  limitation  on  the  number  of  shares  of
Common Stock that may be issued under to the Plan. A s a single share may be subject to grant more
than  once  (  e.g. ,  if  a  share  subject  to  a  Stock  Award  is  forfeited,  it  may  be  made  subject  to  grant
again  as  provided  in  Section  3(b)  below),  the  Share  Reserve  is not  a limit  on  the  number  of  Stock
Awards that can be granted .  

(iii) 

Shares  may  be  issued  under  the  terms  of  this  Plan  in  connection  with  a
merger  or  acquisition  as  permitted  by  NASDAQ  Listing  Rule  5635(c),  NYSE  Listed  Company
Manual  Section  303A.08,  AMEX  Company  Guide  Section  711  or  other  applicable  rule,  and  such
issuance will not reduce the number of shares available for issuance under the Plan.

(b) 

Reversion of Shares to the Share Reserve .   If a Stock Award or any portion of a
Stock Award (i) expires or otherwise terminates without all of the shares covered by the Stock Award
having been issued or (ii) is settled in cash ( i.e. , the Participant receives cash rather than stock), such
expiration,  termination  or  settlement  will  not  reduce  (or  otherwise  offset)  the  number  of  shares  of
Common  Stock  that  are  available  for  issuance  under  the  Plan.      If  any  shares  of  Common  Stock
issued  under  a  Stock  Award  are  forfeited  back  to  or  repurchased  by  the  Company  because  of  the
failure  to  meet  a  contingency  or  condition  required  to  vest  such  shares  in  the  Participant,  then  the
shares that are forfeited or repurchased will revert to and again become available for issuance under
the Plan.   Any shares reacquired by the Company in satisfaction of tax withholding obligations on a
Stock  Award  or  as  consideration  for  the  exercise  or  purchase  price  of  a  Stock  Award  will  again
become available for issuance under the Plan.

(c) 

Source of Shares.   The stock issuable under the Plan will be shares of authorized but
unissued  or  reacquired  Common  Stock,  including  shares  repurchased  by  the  Company  on  the  open
market or otherwise.

Eligibility.

(a) 

Eligibility  for  Specific  Stock  Awards  .      Stock  Awards      may  only  be  granted  to
persons who are Eligible Employees described in Section 1(a) of the Plan, where the Stock Award is
an  inducement  material  to  the  individual’s  entering  into  employment  with  the  Company  or  an
Affiliate within the meaning of Rule 5635(c)(4) of the NASDAQ Listing Rules,   provided however ,
that Stock Awards may not be granted to Eligible Employees who are providing Continuous Service
only  to  any  “parent”  of  the  Company,  as  such  term  is  defined  in  Rule  405  of  the  Securities  Act  ,
unless  (i)  the  stock  underlying  such  Stock  Awards  is  treated  as  “service  recipient  stock”  under
Section  409A  of  the  Code  (for  example,  because  the  Stock  Awards  are  granted  pursuant  to  a
corporate  transaction  such  as  a  spin  off  transaction),  or  (ii)  the  Company,  in  consultation  with  its
legal counsel, has determined that such Stock Awards are otherwise exempt from   or comply with
the distribution requirements of Section 409A of the Code .  

(b) 

Approval Requirements.   All Stock Awards must be granted either by a majority of

the Company’s independent directors or the Independent Compensation Committee .  

5. 

Provisions Relating to Options.

Each  Option  will  be  in  such  form  and  will  contain  such  terms  and  conditions  as  the  Board
deems  appropriate.      All  Options  will  be  Nonstatutory  Stock  Options.  The  provisions  of  separate
Options  need  not  be  identical;  provided,  however  ,  that  each  Option  Agreement  will  conform  to
(through  incorporation  of  provisions  hereof  by  reference  in  the  applicable  Option  Agreement  or
otherwise) the substance of each of the following provisions:

(a) 

Term.   No Option will be exercisable after the expiration of 10 years from the date of

its grant or such shorter period specified in the Option Agreement.

(b) 

Exercise  Price.      The  exercise  or  strike  price  of  each  Option  will  be  not  less  than
100% of the Fair Market Value of the Common Stock subject to the Option on the date the Option is
granted.   Notwithstanding the foregoing, an Option may be granted with an exercise   price lower
than 100% of the Fair Market Value of the Common Stock subject to the Option if such Option is
granted  pursuant  to  an  assumption  of  or  substitution  for  another  option  or  stock  appreciation  right
pursuant to a Corporate Transaction and in a manner consistent with the provisions of Section 409A
of the Code.  

(c) 

Purchase  Pr  ice  for  Options.      The  purchase  price  of  Common  Stock  acquired
pursuant to the exercise of an Option may be paid, to the extent permitted by applicable law and as
determined  by  the  Board  in  its  sole  discretion,  by  any  combination  of  the  methods  of  payment  set
forth  below.      The  Board  will  have  the  authority  to  grant  Options  that  do  not  permit  all  of  the
following methods of payment (or otherwise restrict the ability to use certain methods) and to grant
Options  that  require  the  consent  of  th  e  Company  to  use  a  particular  method  of  payment.      The
permitted methods of payment are as follows:

(i) 

(ii) 

by cash, check, bank draft or money order payable to the Company;

pursuant to a program developed under Regulation T as promulgated by the

Federal Reserve Board that, prior to the issuance of the stock subject to the Option, results in either

5 .

 
the  receipt  of  cash  (or  check)  by  the  Company  or  the  receipt  of  irrevocable  instructions  to  pay  the
aggregate exercise price to the Company from the sales proceeds;

(iii) 
of Common Stock;

by delivery to the Company (either by actual delivery or attestation) of shares

(iv) 

by a “net exercise” arrangement pursuant to which the Company will reduce
the number of shares of Common Stock issuable upon exercise by the largest whole number of shares
with a Fair Market Value that does not exceed the aggregate exercise price; provided, however , that
the Company will accept a cash or other payment from the Participant to the extent of any remaining
balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares
to  be  issued.      Shares  of  Common  Stock  will  no  longer  be  subject  to  an  Option  and  will  not  be
exercisable thereafter to the extent that (A) shares issuable upon exercise are used to pay the exercise
price  pursuant  to  the  “net  exercise,”  (B)  shares  are  delivered  to  the  Participant  as  a  result  of  such
exercise, and (C) shares are withheld to satisfy tax withholding obligations;   or

(v) 

in any other form of legal consideration that may be acceptable to the Board

and specified in the applicable Option Agreement.

(d) 

Transferability  of  Options.      The  Board  may,  in  its  sole  discretion,  impose  such
limitations on the transferability of Options as the Board will determine.   In the absence of such a
determination by the Board to the contrary, the following restrictions on the transferability of Options
will apply:

(i) 

Restrictions on Transfer.   An Option will not be transferable except by will
or by the laws of descent and distribution (or pursuant to subsections (ii) and (iii) below), and will be
exercisable  during  the  lifetime  of  the  Participant  only  by  the  Participant.      The  Board  may  permit
transfer of the Option in a manner that is not prohibited by applicable tax and securities laws. Except
as explicitly provided in the Plan , an Option may not be transferred for consideration.

(ii) 

Domestic Relations Orders.   Subject to the approval of the Board or a duly
authorized Officer, an Option may be transferred pursuant to the terms of a domestic relations order,
official marital settlement agreement   or other divorce or separation instrument .  

(iii) 

Beneficiary  Designation.      Subject  to  the  approval  of  the  Board  or  a  duly
authorized  Officer,  a  Participant  may,  by  delivering  written  notice  to  the  Company,  in  a  form
approved by the Company (or the designated broker), designate a third party who, on the death of the
Participant, will thereafter be entitled to exercise the Option and receive the Common Stock or other
consideration  resulting  from  such  exercise.    In  the  absence  of  such  a  designation,  the  executor  or
administrator  of  the  Participant’s  estate  will  be  entitled  to  exercise  the  Option  and  receive  the
Common  Stock  or  other  consideration  resulting  from  such  exercise.  However,  the  Company  may
prohibit designation  of a beneficiary  at any time, including due to any conclusion  by the Company
that such designation would be inconsistent with the provisions of applicable laws.

(e) 

Vesting  Generally.      The  total  number  of  shares  of  Common  Stock  subject  to  an
Option may vest and therefore become exercisable in periodic installments that may or may not be
equal.   The Option may be subject to such other terms and conditions on the time or times when it

6 .

 
may or may not be exercised (which may be based on the satisfaction of performance goals or other
criteria) as the Board may deem appropriate.   The vesting provisions of individual Options may vary.
  The  provisions  of  this  Section  5(e) are  subject  to  any  Option  provisions  governing  the  minimum
number of shares of Common Stock as to which an Option may be exercised.

(f) 

Termination  of  Continuous  Service.      Except  as  otherwise  provided  in  the
applicable  Option  Agreement  or  other  agreement  between  the  Participant  and  the  Company,  if  a
Participant’s  Continuous  Service  terminates  (other  than  for  Cause  and  other  than  upon  the
Participant’s death or Disability), the Participant may exercise his or her Option   (to the extent that
the  Participant  was  entitled  to  exercise  such  Option  as  of  the  date  of  termination  of  Continuous
Service) within the period of time ending on the earlier of (i) the date which occurs ninety (90) days
following the termination of the Participant’s Continuous Service , and (ii) the expiration of the term
of the Option as set forth in the Option Agreement.   If, after termination of Continuous Service, the
Participant  does  not  exercise  his  or  her  Option  within  the  applicable  time  frame,  the  Option  will
terminate.

(g) 

Extension  of  Termination  Date.      Except  as  otherwise  provided  in  the  applicable
Stock Award Agreement , if the exercise of an Option following the termination of the Participant’s
Continuous Service (other than for Cause and other than upon the Participant’s death or Disability)
would  be  prohibited  at  any  time  solely  because  the  issuance  of  shares  of  Common  Stock  would
violate the registration requirements under the Securities Act, then the Option will terminate on the
earlier  of  (i)  the  expiration  of  a  total  period  of  time  (that  need  not  be  consecutive)  equal  to  the
applicable  post  -  termination  exercise  period  after  the  termination  of  the  Participant’s  Continuous
Service  during  which  the  exercise  of  the  Option  would  not  be  in  violation  of  such  registration
requirements,  and (ii) the expiration  of the term of the Option as set forth in the applicable  Option
Agreement.   In addition, unless otherwise provided in a Participant’s Option Agreement, if the sale
of  any  Common  Stock  received  up  on  exercise  of  an  Option  following  the  termination  of  the
Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading
policy, then the Option will terminate on the earlier of (i) the expiration of a period of days or months
(that  need  not  be  consecutive)  equal  to  the  applicable  post-termination  exercise  period  after  the
termination  of  the  Participant’s  Continuous  Service  during  which  the  sale  of  the  Common  Stock
received  upon  exercise  of  the  Option  would  not  be  in  violation  of  the  Company’s  insider  trading
policy,  or  (ii)  the  expiration  of  the  term  of  the  Option  as  set  forth  in  the  applicable  Option
Agreement.

(h) 

Disability  of  Participant.    Except  as  otherwise  provided  in  the  applicable  Option
Agreement  or  other  agreement  between  the  Participant  and  the  Company,  if  a  Participant’s
Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise
his or her Option (to the extent that the Participant was entitled to exercise such Option as of the date
of termination of Continuous Service), but only within such period of time ending on the earlier of (i)
the date 12 months following such te rmination of Continuous Service   and (ii) the expiration of the
term of the Option as set forth in the Option Agreement.   If, after termination of Continuous Service,
the Participant does not exercise his or her Option within the applicable time frame, the Option will
terminate.

(i) 

Death  of  Participant.      Except  as  otherwise  provided  in  the  applicable  Option

Agreement or other agreement between the Participant and the Company, if (i) a Participant’s

7 .

 
Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within
the period (if any) specified in the Option Agreement for exercisability after the termination of the
Participant’s Continuous Service for a reason other than death, then the Option may be exercised (to
the  extent  the  Participant  was  entitled  to  exercise  such  Option  as  of  the  date  of  death)  by  the
Participant’s  estate,  by  a  person  who  acquired  the  right  to  exercise  the  Option  by  bequest  or
inheritance  or  by  a  person  designated  to  exercise  the  Option  upon  the  Participant’s  death,  but  only
within the period ending on the earlier of (i) the date 18 months following the date of death ,   and (ii)
the  expiration  of  the  term  of  such  Option  as  set  forth  in  the  Option  Agreement.      If,  after  the
Participant’s  death,  the  Option  is  not  exercised  within  the  applicable  time  frame,  the  Option  will
terminate.

(j) 

Termination for Cause.   Except as explicitly provided otherwise in a Participant’s
Stock Award Agreement or other individual written agreement between the Company or any Affiliate
and  the  Participant,  if  a  Participant’s  Continuous  Service  is  terminated  for  Cause,  the  Option  will
terminate  upon  the  date  on  which  the  event  giving  rise  to  the  termination  for  Cause  first  occurred,
and the Participant  will be prohibited  from exercising  his or her Option  from and after the date on
which the event giving rise to the termination for Cause first occurred (or, if required by law, the date
of termination of Continuous Service).   If a Participant’s Continuous Service is suspended pending
an investigation of the existence of Cause, all of the Participant’s rights under the Option will also be
suspended during the investigation period.

(k) 

Non-Exempt  Employees  .   If an Option  is granted  to an Employee  who is a non-
exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, the Option will
not be first exercisable for any shares of Common Stock until at least 6 months following the date of
grant of the Option (although the Option may vest prior to such date). Consistent with the provisions
of  the  Worker  Economic  Opportunity  Act,  (i)  if  such  non-exempt  Employee  dies  or  suffers  a
Disability,  (ii)  upon  a  Corporate  Transaction  in  which  such  Option  is  not  assumed,  continued,  or
substituted, (iii) upon a Change in Control, or (iv) upon the non-exempt Employee ’s retirement (as
such  term  may  be  defined  in  the  non-exempt  Employee’s  Option  Agreement  in  another  agreement
between the non-exempt Employee and the Company,  or, if no such definition,  in accordance  with
the Company's then current employment policies and guidelines), the vested portion of any Options
may  be  exercised  earlier  than  6  months  following  the  date  of  grant.      The  foregoing  provision  is
intended  to  operate  so  that  any  income  derived  by  a  non-exempt  employee  in  connection  with  the
exercise  or  vesting  of  an  Option  will  be  exempt  from  his  or  her  regular  rate  of  pay.  To  the  extent
permitted and/or required for compliance with the Worker Economic Opportunity Act to ensure that
any income derived by a non-exempt E mployee in connection with the exercise, vesting or issuance
of any shares under any other Option will be exempt from such   E mployee’s regular rate of pay, the
provisions of this paragraph will apply to all Options and are hereby incorporated by reference into
such Option Agreements.

6. 

Provisions Relating to Restricted Stock Unit Awards.

Each  Restricted  Stock  Unit  Award  Agreement  will  be  in  such  form  and  will  contain  such
terms and conditions as the Board deems appropriate.   The terms and conditions of Restricted Stock
Unit  Award  Agreements  may  change  from  time  to  time,  and  the  terms  and  conditions  of  separate
Restricted Stock Unit Award Agreements need not be identical.   Each Restricted Stock Unit Award

8 .

 
Agreement  will  conform  to  (through  incorporation  of  the  provisions  hereof  by  reference  in  the
Agreement or otherwise) the substance of each of the following provisions:

(a) 

Consideration.   At  the time  of  grant  of  a Restricted  Stock  Unit  Award,  the  Board
will determine the consideration, if any, to be paid by the Participant upon delivery of each share of
Common Stock subject to the Restricted Stock Unit Award.   The consideration to be paid (if any) by
the  Participant  for  each  share  of  Common  Stock  subject  to  a  Restricted  Stock  Unit  Award  may  be
paid in any form of legal consideration that may be acceptable to the Board , in its sole discretion ,
and permissible under applicable law.

(b) 

Vesting.   At the time of the grant of a Restricted Stock Unit Award, the Board may
impose such restrictions on or conditions to the vesting of the Restricted Stock Unit Award as it, in
its sole discretion, deems appropriate.

(c) 

Payment .   A Restricted Stock Unit Award may be settled by the delivery of shares
of  Common  Stock,  their  cash  equivalent,  any  combination  thereof  or  in  any  other  form  of
consideration,  as  determined  by  the  Board  and  contained  in  the  Restricted  Stock  Unit  Award
Agreement.

(d) 

Additional Restrictions.   At the time of the grant of a Restricted Stock Unit Award,
the Board, as it deems appropriate, may impose such restrictions or conditions that delay the delivery
of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to
a time after the vesting of such Restricted Stock Unit Award.  

(e) 

Dividend Equivalents.   Dividend equivalents may be credited in respect of shares of
Common  Stock  covered  by  a  Restricted  Stock  Unit  Award,  as  determined  by  the  Board  and
contained in the Restricted Stock Unit Award Agreement.   At the sole discretion of the Board, such
dividend  equivalents  may  be  converted  into  additional  shares  of  Common  Stock  covered  by  the
Restricted  Stock  Unit  Award  in  such  manner  as  determined  by  the  Board.    Any additional  shares
covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be
subject  to  all  of  the  same  terms  and  conditions  of  the  underlying  Restricted  Stock  Unit  Award
Agreement to which they relate.

(f) 

Termination of Participant’s Continuous Service.   Except as otherwise provided
in the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit
Award that has not vested will be forfeited upon the Participant’s termination of Continuous Service.

7. 

Covenants of the Company.

(a) 

Availability of Shares.   The Company will keep available at all times the number of

shares of Common Stock reasonably required to satisfy then-outstanding Stock Awards.

(b) 

Securities  Law  Compliance.      The  Company  will  seek  to  obtain  from  each
regulatory commission or agency having jurisdiction over the Plan such authority as may be required
to  grant  Stock  Awards  and  to  issue  and  sell  shares  of  Common  Stock  upon  exercise  of  the  Stock
Awards; provided, however, that this undertaking will not require the Company to register under the
Securities Act the Plan, any Stock Award or any Common Stock issued or

9 .

 
 
issuable pursuant to any such Stock Award.   If, after reasonable efforts and at a reasonable cost, the
Company  is  unable  to  obtain  from  any  such  regulatory  commission  or  agency  the  authority  that
counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under
the Plan, the Company will be relieved from any liability for failure to issue and sell Common Stock
upon exercise of such Stock Awards unless and until such authority is obtained. A Participant will not
be  eligible  for  the  grant  of  a  Stock  Award  or  the  subsequent  issuance  of  cash  or  Common  Stock
pursuant  to  the  Stock  Award  if  such  grant  or  issuance  would  be  in  violation  of  any  applicable
securities law.

(c) 

No Obligation to Notify or Minimize Taxes.   The Company will have no duty or
obligation to any Participant to advise such holder as to the time or manner of exercising such Stock
Award.   Furthermore, the Company will have no duty or obligation to warn or otherwise advise such
holder  of  a  pending  termination  or  expiration  of  a  Stock  Award  or  a  possible  period  in  which  the
Stock Award may not be exercised.    The  Company  has  no  duty  or  obligation  to  minimize  the  tax
consequences of a Stock Award to the holder of such Stock Award .

8. 

Miscellaneous.

(a) 

Use of Proceeds from Sales of Common Stock.   Proceeds from the sale of shares of

Common Stock pursuant to Stock Awards will constitute general funds of the Company.

(b) 

Corporate  Act  ion  Constituting  Grant  of  Stock  Awards.      Corporate  action
constituting a grant by the Company of a Stock Award to any Participant will be deemed completed
as of the date of such corporate action, unless otherwise determined by the Board, regardless of when
the  instrument,  certificate,  or  letter  evidencing  the  Stock  Award  is  communicated  to,  or  actually
received  or  accepted  by,  the  Participant.      In  the  event  that  the  corporate  records  (  e.g.  ,  Board
consents,  resolutions  or  minutes)  documenting  the  corporate  action  constituting  the  grant  contain
terms ( e.g. , exercise price, vesting schedule or number of shares) that are inconsistent with those in
the  Stock  Award  Agreement  as  a  result  of  a  clerical  error  in  the  papering  of  the  Stock  Award
Agreement, the corporate records will control and the Participant will have no legally binding right to
the incorrect term in the Stock Award Agreement.

(c) 

Stockholder Rights.   No Participant will be deemed to be the holder of, or to have
any of the rights of a holder with respect to, any shares of Common Stock subject to a Stock Award
unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of
shares of Common Stock under, the Stock Award pursuant to its terms, and (ii) the issuance of the
Common  Stock  subject  to  such  Stock  Award  has  been  entered  into  the  books  and  records  of  the
Company.

(d) 

No Employment or Other Service Rights.   Nothing in the Plan, any Stock Award
Agreement  or  any  other  instrument  executed  thereunder  or  in  connection  with  any  Stock  Award   
granted pursuant thereto will confer upon any Participant any right to continue to serve the Company
or  an  Affiliate  in  the  capacity  in  effect  at  the  time the  Stock  Award  was  granted  or  will  affect  the
right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without
notice  and  with  or  without  cause  ,  including,  but  not  limited  to,  Cause  ,  (ii)  the  service  of  a
Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate,
or (iii) the service of a Director pursuant to the bylaws of the Company or an

10 .

 
Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the
Affiliate is incorporated, as the case may be.

(e) 

Change in Time Commitment  .   In the event a Participant’s  regular level of time
commitment in the performance of his or her services for the Company and any Affiliates is reduced
(for  example,  and  without  limitation,  if  the  Participant  is  an  Employee  of  the  Company  and  the
Employee  has  a  change  in  status  from  a  full-time  Employee  to  a  part-time  Employee  or  takes  an
extended leave of absence ) after the date of grant of any Stock Award to the Participant, the Board
has the ri ght in its sole discretion to ( i ) make a corresponding reduction in the number of shares or
cash amount subject to any portion of such Stock Award that is scheduled to vest or become payable
after the date of such c hange in time commitment, and ( ii ) in lieu of or in combination with such a
reduction, extend the vesting or payment schedule applicable to such Stock Award . In the event of
any such reduction, the Participant will have no right with respect to any portion of the Stock Award
that is so reduced or extended.

(f) 

Investment Assurances.   The Company may require a Participant, as a condition of
exercising  or  acquiring  Common  Stock  under  any  Stock  Award,  (i)  to  give  written  assurances
satisfactory  to  the  Company  as  to  the  Participant’s  knowledge  and  experience  in  financial  and
business matters and/or to employ a purchaser representative reasonably satisfactory to the Company
who is knowledgeable and experienced in financial and business matters and that he or she is capable
of evaluating, alone or together with the purchaser representative, the merits and risk s of exercising
the  Stock  Award,  and  (ii)  to  give  written  assurances  satisfactory  to  the  Company  stating  that  the
Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account
and  not  with  any  present  intention  of  selling  or  otherwise  distributing  the  Common  Stock.      The
foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative
if (i ) the issuance of the shares upon the exercise of a Stock Award or acquisition of Common Stock
under  the  Stock  Award  has  been  registered  under  a  then  currently  effective  registration  statement
under the Securities Act, or (ii ) as to any particular requirement, a determination is made by counsel
for  the  Company  that  such  requirement  need  not  be  met  in  the  circumstances  under  the  then
applicable  securities  laws.      The  Company  may,  upon  advice  of  counsel  to  the  Company,  place
legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in
order to comply with applicable securities laws, including, but not limited to, legends restricting the
transfer of the Common Stock.

(g) 

Withholding  Obligations.      Unless  prohibited  by  the  terms  of  a  Stock  Award
Agreement, the Company may, in its sole discretion, satisfy any U.S. federal, state, local , foreign or
other tax withholding obligation  relating to a  Stock  Award  by  any  of  the  following  means  or by a
combination  of  such  means:  (i)  causing  the  Participant  to  tender  a  cash  payment;  (ii)  withholding
shares  of  Common  Stock  from  the  shares  of  Common  Stock  issued  or  otherwise  issuable  to  the
Participant in connection with the Stock Award ;   provided,  however , that  no  shares  of  Common
Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by
law  (or  such  other  amount  as  may  be  necessary  to  avoid  classification  of  the  Stock  Award  as  a
liability  for  financial  accounting  purposes);  (iii)  withholding  cash  from  a  Stock  Award  settled  in
cash;  (iv)  withholding  payment  from  any  amounts  otherwise  payable  to  the  Participant  , including
proceeds from the sale of shares of Common Stock issued pursuant to a Stock Award ; or (v) by such
other method as may be set forth in the Stock Award Agreement.  

11 .

 
(h) 

Electronic Delivery .   Any reference herein to a “written” agreement or document
will include any agreement or document delivered electronically , filed publicly at www.sec.gov (or
any  successor  website  thereto),  or  posted  on  the  Company’s  intranet  (or  other  shared  electronic
medium controlled by the Company to which the Participant has access).

(i) 

Deferrals.      To  the  extent  permitted  by  applicable  law,  the  Board,  in  its  sole
discretion,  may  determine  that  the  delivery  of  Common  Stock  or  the  payment  of  cash,  upon  the
exercise,  vesting  or  settlement  of  all  or  a  portion  of  any  Stock  Award  may  be  deferred  and  may
establish  programs  and  procedures  for deferral  elections  to be  made  by Participants.    Deferrals by
Participants will be made in accordance with Section 409A of the Code (to the extent applicable to a
Participant) .   Consistent with Section 409A of the Code , the Board may provide for distributions
while a Participant is still an employee or otherwise providing services to the Company.   The Board
is  authorized  to  make  deferrals  of  Stock  Awards  and  determine  when,  and  in  what  annual
percentages,  Participants  may  receive  payments,  including  lump  sum  payments,  following  the
Participant’s  termination  of  Continuous  Service,  and  implement  such  other  terms  and  conditions
consistent with the provisions of the Plan and in accordance with applicable law.

(j) 

Compliance with Section 409A.   Unless otherwise expressly provided for in a Stock
Award Agreement and the  Plan  will  be  interpreted  to  the  greatest  extent  possible  in  a  manner  that
makes the Plan and the Stock Award s granted hereunder exempt from Section 409A of the Code ,
and,  to  the  extent  not  so  exempt,  in  compliance  with  Section  409A  of  the  Code  .  If  the  Board
determines  that any Stock Award granted  hereunder  is  not  exempt  from  and  is  therefore  subject  to
Section  409A  of  the  Code  ,      the  Stock  Award  Agreement  evidencing  such  Stock  Award  will

specifically  provides  otherwise),  if  the  shares  of  Common  Stock  are  publicly  traded,  and  if  a
Participant holding a Stock Award that constitutes “deferred compensation” under Section 409A of

409A of the Code ) will be issued or paid before the date that is six (6) months following the date of
such Participant’s “separation from service” or, if earlier, the date of the Participant’s death, unless
such distribution or payment can be made in a manner that complies with Section 409A of the Code ,

account  of the  acquisition  of securities  of the Company  by an investor,  any  affiliate  thereof  or any

Board; provided, however, that if the appointment or election (or nomination for election) of any new
Board member was approved or recommended by a majority vote of the members of the Incumbent
Board  then  still  in  office,  such  new  member  will,  for  purposes  of  this  Plan,  be  considered  as  a

services, or (ii) serving as a member of the board of directors of an Affiliate and is compensated for
such services .   However, service solely as a Director, or payment of a fee for such service, will not
cause  a  Director  to  be  considered  a  “Consultant”  for  purposes  of  the  Plan.  Notwithstanding  the
foregoing,  a  person  is  treated  as  a  Consultant  under  this  Plan  only  if  a  Form  S-8  Registration

Employee,  Consultant  or  Director  or  a  change  in  the  Entity  for  which  the  Participant  renders  such
service,  provided  that  there  is  no  interruption  or  termination  of  the  Participant’s  service  with  the
Company  or  an  Affiliate,  will  not  terminate  a  Participant’s  Continuous  Service  .      For  example,  a
change in status from an Employee of the Company to a Consultant of an Affiliate or to a Director
will not constitute  an interruption  of Continuous  Service.   I f the Entity for which a Participant is
rendering services ceases to qualify as an Affiliate, as determined by the Board in its sole discretion,
such Participant’s Continuous Service will be considered to have terminated on the date such Entity
ceases  to  qualify  as  an  Affiliate.  To  the  extent  permitted  by  law,  the  Board  or  the  chief  executive
officer of the Company, in that party’s sole discretion,  may determine whether Continuous  Service
will be considered interrupted in the case of (i )  any leave of absence approved by the Board or chief
executive officer, including sick leave, military leave or any other personal leave, or (ii )  transfers
between the Company, an Affiliate, or their successors.   In addition, if required for exemption from
or  compliance  with  Section  409A  of  the  Code  ,  the  determination  of  whether  there  has  been  a
termination of Continuous Service will be made, and such term will be construed, in a manner that is
consistent  with  the  definition  of  “separation  from  service”  as  defined  under  Treasury  Regulation
Section  1.409A-1(h).      A  leave  of  absence  will  be  treated  as  Continuous  Serv  ice  for  purposes  of
vesting in a Stock Award only to such extent as may be provided in the Company’s leave of absence
policy, in the written terms of any leave of absence agreement or policy applicable to the Participant,
or as otherwise required by law.

Inducement Plan

Option Agreement 
(Nonstatutory Stock Option)

Pursuant to your Stock Option Grant Notice (“ Grant
Notice
”) and this Option Agreement, Sientra,
Inc.  (the  “  Company
 ”)  has  granted  you  an  option  under  its  Inducement  Plan  (the  “  Plan
 ”)  to
purchase the number of shares of the Company’s Common Stock indicated in your Grant Notice at
the exercise price indicated in your Grant Notice.  The option is granted to you effective as of the date
of grant set forth in the Grant Notice (the “ Date
of
Grant
”).  The option is granted in compliance
with NASDAQ  Listing  Rule 5635(c)(4)  as a material  inducement  to you entering  into employment
with the Company. 

If there is any conflict between the terms in this Option Agreement and the Plan, the terms of the Plan
will control. Capitalized terms not explicitly defined in this Option Agreement or in the Grant Notice
but defined in the Plan will have the same definitions as in the Plan.

The  details  of  your  option,  in  addition  to  those  set  forth  in  the  Grant  Notice  and  the  Plan,  are  as
follows:

1. 

Vesting.  Subject to the provisions contained herein, your option will vest as provided

in your Grant Notice.  Vesting will cease upon the termination of your Continuous Service.

2. 

Number  of  Shares  and  Exercise  Price.   The  number  of  shares  of  Common  Stock
subject  to  your  option  and  your  exercise  price  per  share  in  your  Grant  Notice  will  be  adjusted  for
Capitalization Adjustments.

3. 

Exercise Restriction for Non-Exempt Employees.  If you are an Employee eligible
for  overtime  compensation  under  the  Fair  Labor  Standards  Act  of  1938,  as  amended  (  that is , a “
Non-Exempt
Employee
”), and except as otherwise provided in the Plan, you may not exercise your
option  until  you  have  completed  at  least  six  (6)  months  of  Continuous  Service  measured  from  the
Date of Grant, even if you have already been an employee for more than six (6) months. Consistent
with  the  provisions  of  the  Worker  Economic  Opportunity  Act,  you  may  exercise  your  option  as  to
any vested portion prior to such six (6) month anniversary in the case of (i) your death or disability,
(ii)  a  Corporate  Transaction  in  which  your  option  is  not  assumed,  continued  or  substituted,  (iii)  a
Change in Control or (iv) your termination of Continuous Service on your “retirement” (as defined in
the Company’s benefit plans). 

4. 

Method  of  Payment.   You  must  pay  the  full  amount  of  the  exercise  price  for  the
shares  you  wish  to  exercise.    You  may  pay  the  exercise  price  in  cash  or  by  check,  bank  draft  or
money order payable to the Company or in any other manner permitted by your Grant Notice, which
may include one or more of the following:

(a) 

    Provided  that  at  the  time  of  exercise  the  Common  Stock  is  publicly
traded, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve
Board

 
 
 
 
 
that,  prior  to  the  issuance  of  Common  Stock,  results  in  either  the  receipt  of  cash  (or  check)  by  the
Company  or  the  receipt  of  irrevocable  instructions  to  pay  the  aggregate  exercise  price  to  the
Company  from  the  sales  proceeds.    This  manner  of  payment  is  also  known  as  a  “broker-assisted
exercise”, “same day sale”, or “sell to cover”.

 at

  Provided  that

 exercise  the  Common  Stock  is
publicly  traded,  by  delivery  to  the  Company  (either  by  actual  delivery  or  attestation)  of  already-
owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or
security interests, and that are valued at Fair Market Value on the date of exercise.  “Delivery” for
these  purposes,  in  the  sole  discretion  of  the  Company  at  the  time  you  exercise  your  option,  will
include delivery to the Company of your attestation of ownership of such shares of Common Stock in
a form approved by the Company.  You may not exercise your option by delivery to the Company of
Common  Stock  if  doing  so  would  violate  the  provisions  of  any  law,  regulation  or  agreement
restricting the redemption of the Company’s stock.

shares of Common Stock issued upon exercise of your option by the largest whole number of shares
with  a  Fair  Market  Value  that  does  not  exceed  the  aggregate  exercise  price.    You  must  pay  any
remaining balance of the aggregate exercise price not satisfied by the “net exercise” in cash or other
permitted  form  of  payment.    Shares  of  Common  Stock  will  no  longer  be  outstanding  under  your
option  and  will  not  be  exercisable  thereafter  if  those  shares  (i)  are  used  to  pay  the  exercise  price
pursuant  to  the  “net  exercise,”  (ii)  are  delivered  to  you  as  a  result  of  such  exercise,  and  (iii)  are

shares of Common Stock issuable upon exercise are then registered under the Securities Act or, if not
registered, the Company has determined that your exercise and the issuance of the shares would be
exempt  from  the  registration  requirements  of  the  Securities  Act.    The  exercise  of  your  option  also
must comply with all other applicable laws and regulations governing your option, and you may not
exercise  your  option  if  the  Company  determines  that  such  exercise  would  not  be  in  material
compliance  with  such  laws  and  regulations  (including  any  restrictions  on  exercise  required  for
compliance with Treas. Reg. 1.401(k)-1(d)(3), if applicable).

7. 

Term.   You  may  not  exercise  your  option  before  the  Date  of  Grant  or  after  the

Law Compliance,” your option will not expire until the earlier of the Expiration Date or until it has
been exercisable for an aggregate period of sixty (60) days after the termination of your Continuous
Service; provided further, if during any part of such sixty (60) day period, the sale of any Common
Stock received upon exercise of your option would violate the Company’s insider trading policy, then
your option will not expire until the earlier of the Expiration Date or until it has been exercisable for
an aggregate period of sixty (60) days after the termination of your Continuous Service during which
the sale of the Common Stock received upon exercise of your option would not be in violation of the
Company’s  insider  trading  policy.    Notwithstanding  the  foregoing,  if  (i)  you  are  a  Non-Exempt
Employee, (ii) your Continuous Service terminates within six (6) months after the Date of Grant, and

option  with  the  Company  prior  to  finalizing  the  domestic  relations  order  or  marital  settlement
agreement to help ensure the required information is contained within the domestic relations order or

consideration resulting from such exercise.

10.

contract, and nothing in your option will be deemed to create in any way whatsoever any obligation
on  your  part  to  continue  in  the  employ  of  the  Company  or  an  Affiliate,  or  of  the  Company  or  an
Affiliate  to  continue  your  employment.    In  addition,  nothing  in  your  option  will  obligate  the
Company or an Affiliate, their respective stockholders, boards of directors, officers or employees to
continue  any  relationship  that  you  might  have  as  a  Director  or  Consultant  for  the  Company  or  an

tax liabilities. You will not make any claim against the Company, or any of its Officers, Directors,
Employees or Affiliates related to tax liabilities arising from your option or your other compensation.
In particular, you acknowledge that this option is exempt from Section 409A of the Code only if the
exercise price per share specified in the Grant Notice is at least equal to the “fair market value” per
share  of  the  Common  Stock  on  the  Date  of  Grant  and  there  is  no  other  impermissible  deferral  of

Company or another third party designated by the Company.

the  provisions  of  which  are  hereby  made  a  part  of  your  option,  and  is  further  subject  to  all
interpretations, amendments, rules and regulations, which may from time to time be promulgated and
adopted pursuant to the Plan.  If there is any conflict between the provisions of your option and those
of the Plan, the provisions of the Plan will control.  In addition, your option (and any compensation
paid  or  shares  issued  under  your  option)  is  subject  to  recoupment  in  accordance  with  The  Dodd–
Frank  Wall  Street  Reform  and  Consumer  Protection  Act  and  any  implementing  regulations
thereunder,  any  clawback  policy  adopted  by  the  Company  and  any  compensation  recovery  policy
otherwise required by applicable law.

Effect  on  Other  Employee  Benefit  Plans  .    The  value  of  this  option  will  not  be
included  as  compensation,  earnings,  salaries,  or  other  similar  terms  used  when  calculating  your
benefits under any employee benefit plan sponsored by the Company or any Affiliate, except as such
plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or
terminate any of the Company’s or any Affiliate’s employee benefit plans.

17. 

Voting Rights .  You will not have voting or any other rights as a stockholder of the
Company with respect to the shares to be issued pursuant to this option until such shares are issued to
you.    Upon  such  issuance,  you  will  obtain  full  voting  and  other  rights  as  a  stockholder  of  the
Company.    Nothing  contained  in  this  option,  and  no  action  taken  pursuant  to  its  provisions,  will
create or be construed to create a trust of any kind or a fiduciary relationship  between you and the
Company or any other person.

18. 

Severability .  If all or any part of this Option Agreement or the Plan is declared by
any court or governmental  authority  to be unlawful  or invalid,  such unlawfulness  or invalidity  will
not  invalidate  any  portion  of  this  Option  Agreement  or  the  Plan  not  declared  to  be  unlawful  or
invalid.  Any Section of this Option Agreement (or part of such a Section) so declared to be unlawful
or  invalid  shall,  if  possible,  be  construed  in  a  manner  which  will  give  effect  to  the  terms  of  such
Section or part of a Section to the fullest extent possible while remaining lawful and valid.

”) . The Award is granted in compliance with NASDAQ Listing Rule

The details of your Award, in addition to those set forth in the Grant Notice and the Plan are

as follows:

bookkeeping account maintained by the Company for your benefit (the “ Account

Stock Units subject to the Award.  This Award was granted in consideration of your services to the
Company.

21. 

Vesting .  Subject to the provisions contained herein, your Award will vest, if at all, in
accordance  with  the  vesting  schedule  provided  in  the  Grant  Notice.    Vesting  will  cease  upon  the
termination of your Continuous Service for any reason.  Upon such termination of your Continuous
Service,  any  Stock  Units  credited  to  the  Account  that  were  not  yet  vested  on  the  date  of  such
termination  will  be  forfeited  at  no  cost  to  the  Company  and  you  will  have  no  further  right,  title  or

Company the proposed terms of any such transfer prior to finalizing the domestic relations order or
marital settlement agreement to help ensure the required information is contained within the domestic
relations  order,  marital  settlement  agreement  or  other  divorce  or  separation  instrument.    The

apply with respect to any shares of Common Stock that are delivered to you in connection with your
Award after such shares have been delivered to you.

27.

any specified term and may be terminated by you or by the Company or an Affiliate at any time, for
any  reason,  with  or  without  cause  and  with  or  without  notice.    Nothing  in  this  Award  Agreement
(including, but not limited to, the vesting of your Stock Units or the issuance of the shares in respect
of  your  Stock  Units),  the  Plan  or  any  covenant  of  good  faith  and  fair  dealing  that  may  be  found
implicit in this Award Agreement or the Plan will:  (i) confer upon you any right to continue in the
employ or service of, or affiliation with, the Company or an Affiliate; (ii) constitute any promise or
commitment by the Company or an Affiliate regarding the fact or nature of future positions, future
work assignments, future compensation or any other term or condition of

 
 
 
 
employment or affiliation; (iii) confer any right or benefit under this Award Agreement or the Plan

Plan;  or  (iv)  deprive  the  Company  of  the  right  to  terminate  you  at  will  and  without  regard  to  any
future vesting opportunity that you may have.

  By  accepting  this  Award,

 you  acknowledge  and  agree  that
the  right  to  continue  vesting  in  the  Award  pursuant  to  the  vesting  schedule  provided  in  the  Grant
Notice is earned only by continuing as an employee, director or consultant at the will of the Company
or  an  Affiliate,  as  applicable  (not  through  the  act  of  being  hired,  being  granted  this  Award  or  any
other award or benefit) and that the Company has the right to reorganize, sell, spin-out or otherwise
restructure one or more of its businesses or Affiliates at any time or from time to time, as it deems
appropriate  (a  “  Reorganization
”).    You  further  acknowledge  and  agree  that  such  Reorganization
could  result  in  the  termination  of  your  Continuous  Service or  the  termination  of  Affiliate  status  of
your employer and the loss of benefits available to you under this Award Agreement , including but
not  limited  to,  the  termination  of  the  right  to  continue  vesting  in  the  Award.    You  further
acknowledge  and  agree  that  this  Award  Agreement  ,  the  Plan,  the  transactions  contemplated
hereunder and the vesting schedule set forth herein or any covenant of good faith and fair dealing that
may be found implicit in any of them do not constitute an express or implied promise of continued
engagement as an employee or consultant for the term of this Award Agreement, for any period, or at
all,  and  shall  not  interfere  in  any  way  with  your  right  or  the  Company’s  right  to  terminate  your
Continuous Service at any time, with or without cause and with or without notice.

29.  Withholding Obligations.

(a) 

  On  each  vesting  date,

 and  on  or  before  the  time  you  receive
a  distribution  of  the  shares  in  respect  of  your  Stock  Units,  and  at  any  other  time  as  reasonably
requested by the Company in accordance with applicable tax laws, you hereby authorize any required
withholdings  from  the  shares  of  Common  Stock  issuable  to  you  and/or  otherwise  agree  to  make
adequate  provision,  including  in  cash,  for  any  sums  required  to  satisfy  the  federal,  state,  local  and
foreign  tax  withholding  obligations  of  the  Company  or  any  Affiliate  that  arise  in  connection  with
your Award (the “ Withholding
Taxes
”).  Specifically, the Company or an Affiliate may, in its sole
discretion, satisfy all or any portion of the Withholding Taxes relating to your Award by any of the
following  means  or  by  a  combination  of  such  means:  (i)  withholding  from  any  compensation
otherwise payable to you by the Company or an Affiliate; (ii) causing you to tender a cash payment;
(iii) permitting or requiring you to enter into a “same day sale” commitment with a broker-dealer that
is  a  member  of  the  Financial  Industry  Regulatory  Authority  (a  “  FINRA 
Dealer
 ”)  whereby  you
irrevocably elect to sell a portion of the shares to be delivered in connection with your Stock Units to
satisfy the Withholding  Taxes  and whereby  the FINRA  Dealer  irrevocably  commits  to forward  the
proceeds necessary to satisfy the Withholding Taxes directly to the Company and/or its Affiliates; or
(iv)  withholding  shares  of  Common  Stock  from  the  shares  of  Common  Stock  issued  or  otherwise
issuable  to you in connection  with your Stock  Units with a Fair Market Value  (measured  as of the
date  shares  of Common  Stock  are  issued  to you)  equal  to the amount  of such  Withholding  Taxes;
provided, however , that the number of such shares of Common Stock so withheld will not exceed the
amount necessary to satisfy the Company’s required tax withholding obligations using the minimum
statutory withholding rates for federal, state, local and, if applicable, foreign tax purposes, including
payroll  taxes,  that  are  applicable  to  supplemental  taxable  income;  and  provided  further,  that  to  the
extent necessary to qualify for an

 
 
 
 
 
exemption from application of Section 16(b) of the Exchange Act, such share withholding procedure
shall be subject to the express prior approval of the Board or a duly authorized committee thereof.

Severability.  If all or any part of this Award Agreement or the Plan is declared by
any court or governmental  authority  to be unlawful  or invalid,  such unlawfulness  or invalidity  will

39. 

Compliance with Section 409A of the Code .  This Award is intended to be exempt
from  the  application  of  Section  409A  of  the  Code,  including  but  not  limited  to  by  reason  of
complying with the “short-term deferral” rule set forth in Treasury Regulation Section 1.409A-1(b)
(4)  and  any  ambiguities  herein  shall  be  interpreted  accordingly.    However,  if  this  Award  fails  to
satisfy  the  requirements  of  the  short-term  deferral  rule  and  is  otherwise  not  exempt  from,  and
therefore deemed to be deferred compensation subject to, Section 409A of the Code, this Award shall
comply  with  Section  409A  of  the  Code  to  the  extent  necessary  to  avoid  adverse  personal  tax
consequences and any ambiguities herein shall be interpreted accordingly.  To the extent this Award
is subject to Section 409A of the Code and if you are a “Specified Employee” (within the meaning
set forth Section 409A(a)(2)(B)(i) of the Code) as of the date of your separation from service (within
the meaning of Treasury Regulation Section 1.409A-1(h)), then the issuance of any shares that would
otherwise  be  made  upon  the  date  of  the  separation  from  service  or  within  the  first  six  months
thereafter will not be made on the originally scheduled dates and will instead be

 
 
 
issued in a lump sum on the date that is six months and one day after the date of the separation from
service, with the balance of the shares issued thereafter in accordance with the original vesting and
issuance  schedule  set  forth  above,  but  if  and  only  if  such  delay  in  the  issuance  of  the  shares  is
necessary to avoid the imposition of taxation on you in respect of the shares under Section 409A of
