ITEM 1. BUSINESS

PART I

Overview

We are a materials company focused on developing, manufacturing and selling silicon nitride ceramics that are used in medical implants
and in a variety of industrial devices. At present, we commercialize silicon nitride in the spine implant market. We believe that our versatile
silicon  nitride  manufacturing  expertise  positions  us  favorably  to  introduce  new  and  innovative  devices  in  the  medical  and  non-medical
fields. We also believe that we are the first and only company to commercialize silicon nitride medical implants.

We  have  received  510(k)  regulatory  clearance  in  the  United  States,  a  CE  mark  in  Europe, ANVISA  approval  in  Brazil,  and ARTG  and
Prostheses approvals in Australia for a number of our devices that are designed for spinal fusion surgery. To date, more than 33,000 of our
silicon  nitride  devices  have  been  implanted  into  patients,  with  a  10-year  successful  track  record.  In  March  2018,  we  received  clearance
from the United States Food and Drug Administration, or FDA, to market a modified novel composite spinal fusion device that combines
porous and solid silicon nitride, and is comparable to our commercially-available Valeo®C cervical implants.

We  believe  that  silicon  nitride  has  a  superb  combination  of  properties  that  make  it  ideally  suited  for  human  implantation.  Other
biomaterials are based on bone grafts, metal alloys, and polymers- all of which have practical limitations. In contrast, silicon nitride has a
legacy  of  success  in  the  most  demanding  and  extreme  industrial  environments. As  a  human  implant  material,  silicon  nitride  offers  bone
ingrowth, resistance to bacterial infection, resistance to corrosion, superior strength and fracture resistance, and ease of diagnostic imaging,
among other advantages.

We market and sell our Valeo brand of silicon nitride implants to surgeons and hospitals in the United States and to selected markets in
Europe  and  South America  through  more  than  50  independent  sales  distributors  who  are  supported  by  an  in-house  sales  and  marketing
management  team.  These  implants  are  designed  for  use  in  cervical  (neck)  and  thoracolumbar  (lower  back)  spine  surgery.  In  2016  we
entered into a 10-year exclusive distribution agreement with Shandong Weigao Orthopaedic Device Company Limited (“Weigao”) to sell
Amedica-branded  silicon  nitride  spinal  fusion  devices  within  the  People’s  Republic  of  China  (“China”).  Weigao,  a  large  orthopedic
company, has expertise in acquiring Chinese Food and Drug Administration (“CFDA”) approval of medical devices, and will assist us in
obtaining regulatory approval. Weigao has committed to minimum purchase requirements totaling 225,000 implants in the first six years
following  CFDA  clearance.  We  are  also  working  with  other  partners  in  Japan  to  obtain  regulatory  approval  for  silicon  nitride  in  that
country. China and Japan are relevant because historically, ceramic implants are more familiar to, and more readily accepted by surgeons
outside the United States, i.e., in Asia and Europe.

In addition to silicon nitride, we also sell metal-based products in the United States that provide surgeons and hospitals with a complete
package  for  spinal  surgery.  These  metal  products  are  designed  to  address  spinal  deformity  and  degenerative  conditions. Although  these
metal products have accounted for approximately 53% and 48% of our product revenues for each of the years ended December 31, 2017
and 2016, respectively, we remain focused on developing and promoting silicon nitride, and driving its adoption through a scientifically-
intense, data-driven strategy.

In addition to direct sales, we have targeted original equipment manufacturer (“OEM”) and private label partnerships in order to accelerate
adoption  of  silicon  nitride,  both  in  the  spinal  space,  and  also  in  future  markets  such  as  hip  and  knee  replacements,  dental,  extremities,
trauma,  and  sports  medicine.  Existing  biomaterials,  based  on  plastics,  metals,  and  bone  grafts  have  well-recognized  limitations  that  we
believe  are  addressed  by  silicon  nitride,  and  we  are  uniquely  positioned  to  convert  existing,  successful  implant  designs  made  by  other
companies into silicon nitride. We believe OEM and private label partnerships will allow us to work with a variety of partners, accelerate
the adoption of silicon nitride, and realize incremental revenue at improved operating margins, when compared to the cost-intensive direct
sales model.

We  believe  that  silicon  nitride  addresses  many  of  the  biomaterial-related  limitations  in  fields  such  as  hip  and  knee  replacements,  dental
implants, sports medicine, extremities, and trauma surgery. We further believe that the inherent material properties of silicon nitride, and
the ability to formulate the material in a variety of compositions, combined with precise control of the surface properties of the material,
opens up a number of commercial opportunities across orthopedic surgery, neurological surgery, maxillofacial surgery, and other medical
disciplines.

We operate a 30,000 square foot manufacturing facility at our corporate headquarters in Salt Lake City, Utah, and we believe we are the
only vertically integrated silicon nitride medical device manufacturer in the world.

Biomaterials

Biomaterials are natural or synthetic biocompatible materials that are used in virtually every medical specialty to improve or preserve body
functionality. Various types of biomaterials are used as essential components in medical devices, drug delivery systems, replacement and
tissue repair technologies, prostheses, and diagnostic technologies.

There are four general categories of biomaterials:

● Ceramics. Ceramics  are  hard,  non-metallic,  non-corrosive,  heat-resistant  materials  made  by  shaping  and  then  applying  high
temperatures. Traditional  ceramics  commonly  used  as  biomaterials  include  carbon,  oxides  of  aluminum,  zirconium  and  titanium,
calcium  phosphate and  zirconia-toughened  alumina.  Examples  of  medical  uses  of  ceramics  include  repair,  augmentation  or
stabilization  of  fractured bones, bone and joint replacements, spinal fusion devices, dental implants and restorations, heart valves
and surgical instruments.

● Metals. Metals commonly used as biomaterials include titanium, stainless steel, cobalt, chrome, gold, silver and platinum, and alloys
of  these  metals.  Examples  of  medical  uses  of  metals  include  the  repair  or  stabilization  of  fractured  bones,  stents, surgical
instruments, bone and joint replacements, spinal fusion devices, dental implants and restorations and heart valves.

● Natural biomaterials. Natural  biomaterials  are  derived  from  human  donors,  animal  or  plant  sources  and  include  human  bone,
collagen, gelatin,  cellulose,  chitin,  alginate  and  hyaluronic  acid.  Examples  of  medical  uses  of  natural  biomaterials  include  the
addition or substitution of hard and soft tissue, cornea protectors, vascular grafts, repair and replacement of tendons and ligaments,
bone and joint replacements, spinal fusion devices, dental restorations and heart valves.

● Polymers. Polymers  are  synthetic  compounds  consisting  of  similar  molecules  linked  together  that  can  be  created  to  have  specific
properties.  Polymers  commonly  used  as  biomaterials  include  nylon,  silicon  rubber,  polyester,  polyethylene,  cross-linked
polyethylene (a  stronger  version),  polymethylmethacrylate,  polyvinyl  chloride  and  polyetheretherketone  –  which  is  commonly
referred to as PEEK. Examples of medical uses of polymers include soft-tissue replacement, sutures, drug delivery systems, joint
replacements, spinal fusion devices and dental restorations.

Within orthopedics, biomaterials are extensively used in spinal fusion procedures, hip and knee replacements and the repair or stabilization
of  fractured  bones.  Currently, Amedica  is  the  only  FDA-cleared  and  ISO  13485  certified  silicon  nitride  medical  device  manufacturing
facility in the world. We believe we are the only provider of ceramics-based medical devices used for spinal fusion applications.

Overview

Market Opportunity

We  believe  our  silicon  nitride  biomaterial  technology  platform  provides  us  with  numerous  competitive  advantages  in  the  orthopedic
biomaterials market. We market interbody spinal fusion devices and related products and are developing products for use as components in
total hip and knee joint replacements, as well as dental applications. We believe we can also utilize our silicon nitride technology platform
to develop future products in additional markets, such as the sports medicine, extremities, and trauma markets.

Of the interbody spinal fusion procedures conducted in the United States today, a significant majority utilized interbody devices comprised
of PEEK and bone, with occasional use of metals and other materials including ceramics. The market for interbody spinal fusion devices
has shifted over time as new biomaterials with superior characteristics have been incorporated into these devices and have launched into the
market.  We  believe  the  market  has  reached  another  inflection  point  as  surgeons  and  hospitals  recognized  the  limitations  of  devices
currently  available.  Similarly,  we  believe  our  silicon  nitride  interbody  spinal  fusion  products  address  the  key  limitations  of  other
biomaterials currently used in interbody spinal fusion devices and demonstrate superior characteristics needed to improve clinical outcomes.

We  believe  that  the  main  drivers  for  growth  within  the  orthopedic  biomaterials  market  and,  in  particular,  the  spinal  fusion  and  joint
replacement markets, are the following:

● Introduction of  New  Technologies.   Better  performing  and  longer-lasting  biomaterials,  improved  diagnostics,  and  advances  in
surgical procedures  allow  for  surgical  intervention  earlier  in  the  continuum  of  care  and  better  outcomes  for  patients.  We  believe
surgical options using better performing and longer-lasting biomaterials will gain acceptance among surgeons and younger patients
and drive accelerated growth and increase the size of the spinal fusion and joint replacement markets.

● Favorable and  Changing  Demographics. With  the  growing  number  of  elderly  people,  age-related  ailments  are  expected  to  rise
sharply, which we believe will increase the demand and need for biomaterials and devices with improved performance capabilities.
Also, middle-aged and older patients increasingly expect to enjoy active lifestyles, and consequently demand effective treatments
for  painful  spine  and  joint  conditions,  including  better  performing  and  longer-lasting  interbody  spinal  fusion  devices  and joint
replacements.

● Market Expansion into New Geographic Areas. We anticipate that demand for biomaterials and the associated medical devices will
increase  as  the  applications  in  which  biomaterials  are  used  are  introduced  to  and  become  more  widely  accepted  in  underserved
countries, such as Brazil and China.

The Interbody Spinal Fusion Market

The human spinal canal is made up of 33 interlocking bones, referred to as vertebrae, separated by 23 intervertebral discs comprised of a
hard outer ring made of collagen with a soft inner core, that act as shock absorbers between vertebrae. Disorders of the spine can result
from  degenerative  conditions,  deformities  and  trauma  or  tumor-related  damage.  Spinal  fusion  is  the  standard  of  care  used  to  treat  most
spinal disorders and typically involves the placement of an interbody device between vertebrae  to  reestablish  spacing  between  vertebrae
and alignment of the spine. Generally, the interbody device is stabilized by screws and, in some procedures, plates or rods. To enhance bone
attachment,  surgeons  often  pack  the  interbody  device  with  a  biomaterial  that  induces  bone  growth.  Following  successful  treatment,  new
bone  tissue  grows  in  and  around  the  interbody  device  over  time,  which  helps  fuse  the  vertebrae  and  create  long-term  stability  of  the
interbody device, leading to the alleviation of pain and increase in mobility. We selected this market as the first application for our silicon
nitride technology because of the limitations of currently available products, its size, and the key characteristics silicon nitride possesses,
which are critical for superior interbody spinal fusion outcomes.

● Promotion of Bone Growth. The biomaterial should be both osteoconductive and create an osteoinductive environment to promote
bone growth in and around the interbody device to further support fusion and stability. Osteoconduction occurs when material serves
as  a  scaffold  to  support  the  growth  of  new  bone  in  and  around  the  material.  Osteoinduction  involves  the  stimulation  of
osteoprogenitor cells to develop, or differentiate, into osteoblasts, which are cells that are needed for bone growth. A material which
stimulates bone growth and accelerates fusion rates is ideal in spinal fusion procedures.

● Antibacterial. Spinal  fusion  devices  can  become  colonized  with  bacteria,  which  may  limit  fusion  to  adjacent  vertebrae  or  cause
serious infection. Treating device-related infection is costly and generally requires repeat surgery, including surgery to replace the
device, referred to as revision surgery, which may extend hospital stays, suffering and disability for patients. A biomaterial  that has
antibacterial  properties  can  reduce  the  incidence  of  bacteria  colonization  in  and  around  the  interbody  device  that can  lead  to
infection, revision surgery and associated increased costs.

● Imaging Compatibility. The  biomaterial  should  be  visible  through,  and  not  inhibit  the  effective  use  of,  common  surgical  and
diagnostic imaging techniques, such as X-ray, CT and MRI. These imaging techniques are used by surgeons during and after spinal
fusion procedures to assist in the proper placement of interbody devices and to assess the quality of post-operative bone fusion.

● Strength and Resistance to Fracture. The biomaterial should be strong and resistant to fracture during implantation of the device and
to successfully restore intervertebral disc space and spinal alignment during the fusion process. The biomaterial should have high
flexural strength, which is the ability to resist breakage during bending, and high compressive strength, which is the ability to resist
compression  under  pressure,  to  withstand  the  static  and  dynamic  forces  exerted  on  the  spine  during daily  activities  over  the  long
term.

Limitations of Biomaterials used in Interbody Spinal Fusion Devices

The three biomaterials most commonly used in interbody spinal fusion devices are PEEK, human cadaver bone, also referred to as allograft
bone, and metals. We believe these materials do not possess the key characteristics required to form the optimal interbody spinal fusion
device  and  are  susceptible  to  potential  fracture,  implant-related  infection,  pain,  limited  fusion  and  instability,  which  have  resulted  in
revision surgeries.

PEEK (polyetheretherketone)

We believe PEEK is the most frequently used biomaterial for interbody spinal devices and accounted for the majority of interbody spinal
devices implanted in the United States in 2017. We believe PEEK has the following limitations:

● Restricts Bone  Growth. Due  to  PEEK’s  hydrophobic  nature,  the  human  body  may  recognize  PEEK  as  a  foreign  substance  and,
therefore, may encapsulate the device with fibrous tissue. Although it is still possible for bone to grow through the device, bone may
not  adhere  to  the  surface  of  the  device  if  this  tissue  develops.  This  fibrous  layer  could  cause  a  non-fusion,  allow  bacterial
colonization, and/or potentially lead to costly revision surgery.

● Lacks Imaging Compatibility. PEEK is invisible on X-rays. As a result, manufacturers of PEEK devices add metal markers to their
devices so surgeons can see the general location of the devices by X-ray. These markers, however, do not show the full outline  of
the  device,  which  makes  it  difficult  to  assess  the  accuracy  of  the  placement  of  the  device.  In  addition,  the  metal  markers cause
artifacts on CT and MRI that can compromise the quality of the image.

● Lacks Strength and Resistance to Fracture. PEEK lacks sufficient flexural strength, compressive strength and resistance to fracture
necessary  to  reduce  the  risk  of  deformity  or  fracture  during  the  fusion  process.  In  addition,  PEEK  devices  may  fracture  during
implantation  in  certain  interbody  spinal  fusion  procedures.  For  example,  in  December  2012,  Zimmer  Spine  recalled  its  PEEK
Ardis® Interbody System Inserter, a surgical instrument used to implant a PEEK interbody spinal fusion device, because it resulted
in the PEEK implants being susceptible to breakage when too much lateral force was applied to the inserter during implantation.
Due to radiographic X-rays being the most common way for surgeons to assess fusion, and PEEK being invisible on X-rays, it is
extremely difficult to clearly assess the extent to which fracture rates occur with PEEK interbody fusion devices.

● Lacks Antibacterial  Properties. PEEK  does  not  have  any  inherent  antibacterial  properties.  In  fact,  a  biofilm  may  form  around a
PEEK  device  after  implantation,  which  could  allow  for  the  colonization  of  bacteria,  leading  to  infection  and  costly  revision
surgeries.

Allograft Bone

We believe allograft bone was the second most frequently used biomaterial in interbody spinal fusion devices in the United States in 2017.
We believe allograft bone has the following limitations:

● Limited Promotion  of  Bone  Growth. Allograft  bone  has  limited  osteoinductive  characteristics  and  therefore  may  not  effectively

promote bone growth in and around the interbody device.

● Inconsistent Quality.  Generally,  allograft  bone  is  not  as  strong  as  live  bone  within  the  body  or  other  materials  used  in  interbody
devices.  Because  the  cadaveric  bone  can  be  harvested  from  a  wide  variety  of  sources,  this  often  leads  to  inconsistent  patient
outcomes. Allograft bone is subject to inconsistent quality and size, which may require surgeons to make compromises on the fit of
the device during surgery. In addition, techniques used to sterilize allograft bone, like gamma irradiation, can cause the allograft to
become brittle and more susceptible to fracture.

● Lacks Antibacterial  Properties  and  Risk  of  Disease  Transmission.  In  addition  to  not  having  inherent  antibacterial  properties,

allograft bone exposes patients to a greater risk of disease transmission and an adverse auto-immune response.

Metals

We believe metal interbody devices accounted for a fraction of the devices implanted in the United States in 2016. We believe metal-based
interbody fusion devices have the following limitations:

● Limited Promotion  of  Bone  Growth.  Metals  have  limited  osteoinductive  characteristics  and  therefore  do  not  effectively  promote

bone growth in and around the interbody device.

● Lack Antibacterial Properties. Metals do not have inherent antibacterial properties and do not suppress the colonization of bacteria

in and around the device, which can lead to infection and/or costly revision surgeries.

● Lack Imaging Compatibility. Metals are opaque in X-rays and can cause significant imaging artifacts in CTs and MRIs. This can
make it difficult for surgeons to detect the extent and quality of bone growth in and around the device in post-operative diagnostic
imaging procedures.

The Hip and Knee Joint Replacement Market

Total  joint  replacement  involves  removing  the  diseased  or  damaged  joint  and  replacing  it  with  an  artificial  implant  consisting  of
components made from several different types of biomaterials. The key components of a total hip implant include an artificial femoral head,
consisting of a ball mounted on an artificial stem attached to the femur, and a liner, which is placed inside a cup affixed into the pelvic
bone. The femoral head and liner move against each other to replicate natural motion in what is known as an articulating implant. Total
knee replacement implants also use articulating components and are comprised of the following four main components: a femoral condyle,
which is a specially shaped bearing that is affixed to the lower end of the femur; a tibial tray that is affixed to the upper-end of the tibia; a
tibial insert that is rigidly fixed to the tibial tray and serves as the surface against which the femoral condyle articulates; and a patella, or
knee cap, which also articulates against the femoral condyle.

Implants for total hip and knee replacements are primarily differentiated by the biomaterials used in the components that articulate against
one another. The combinations of biomaterials most commonly used in hip and knee replacement implants in the United States are metal-
on-cross-linked  polyethylene  and  traditional  oxide  ceramic-on-cross-linked  polyethylene.  The  use  of  hip  replacement  implants
incorporating metal-on-metal and traditional oxide ceramic-on-traditional ceramic biomaterials experienced a steep decline in the United
States  over  the  last  several  years  due  to  their  significant  limitations.  We  believe  that  the  most  commonly  used  biomaterials  in  joint
replacement  implants  also  have  limitations,  and  do  not  possess  all  of  the  following  key  characteristics  required  for  optimal  total  joint
replacement implants:

● Resistance to  Wear.  The  biomaterials  should  have  sufficient  hardness  and  toughness,  as  well  as  extremely  smooth  surfaces,  to
effectively resist  wear.  Because  the  articulating  implants  move  against  each  other,  they  are  subject  to  friction,  which  frequently
leads to abrasive wear and the release of small wear particles. This may cause an inflammatory response which results in osteolysis,
or bone loss. Surgeons have identified osteolysis as a leading cause of joint implant failure, resulting in the need for costly revision
surgery  to  replace  the  failed  implant.  One  of  the  most  commonly  used  combinations  of  biomaterials,  metal-on-cross-linked
polyethylene,  as  well  as  metal-on-metal  implants,  tends  to  generate  a  large  number  of  metal  wear  particles,  which  can  cause
osteolysis  and  a  moderate  to  severe  allergic  reaction  to  the  metal,  referred  to  as  metal  sensitivity.  While  less  common,  metal
implants may also cause a serious medical condition called metallosis, which involves the deposition and build-up of metal debris in
the soft tissues of the body. Both metal sensitivity and metallosis can result in revision surgery. In addition,  we believe traditional
oxide ceramics currently used in total joint replacements accelerate wear of the cross-linked polyethylene liner as compared to our
non-oxide ceramic composition found in our silicon nitride biomaterial platform.

● Non-Corrosive. The biomaterials should be non-corrosive and should not cause adverse patient reactions. Metal placed in the human
body corrodes over time and also results in the formation of metal ions, which leads to metal sensitivity in approximately 10% to
15% of the population and, less commonly, metallosis. As a result, there are significant increased risks from using metal-on-cross-
linked polyethylene and metal-on-metal implants.

● Hardness, Strength and Resistance to Fracture. The biomaterials should be hard, strong and resistant to fracture to adequately bear
the significant loads placed on the hip and knee joints during daily activities. We believe there are strength limitations associated
with traditional oxide ceramic-on-cross-linked polyethylene and traditional oxide ceramic-on-traditional oxide ceramic implants.

● Antibacterial. The  biomaterials  should  have  antibacterial  properties  to  reduce  the  risk  of  bacteria  colonization,  infection,  revision
surgeries  and  associated  increased  costs.  None  of  the  most  commonly  used  biomaterials  in  joint  replacement  implants  have
antibacterial properties.

Our Silicon Nitride Technology Platform

We believe we are the only FDA-cleared and ISO 13485 certified silicon nitride medical device manufacturing facility in the world, and the
only provider of ceramics-based medical devices used for spinal fusion applications. Silicon nitride is a chemical compound comprised of
the  elements  silicon  and  nitrogen,  with  the  chemical  formula  Si3N4.  Silicon  nitride,  an  advanced  ceramic,  is  lightweight,  resistant  to
fracture and strong, and is used in many demanding mechanical, thermal and wear applications, such as in space shuttle bearings, jet engine
components and body armor.

We  believe  our  silicon  nitride  is  ideally  suited  for  use  in  many  medical  applications  and  has  the  following  characteristics  that  make  it
superior  to  other  biomaterials,  including  PEEK,  bone,  metal  and  traditional  oxide  ceramics,  which  do  not  possess  all  of  these
characteristics:

● Promotes Bone Growth. Our silicon nitride is osteoconductive through its inherent surface topography that provides scaffolding for
new  bone  growth.  We  believe  our  silicon  nitride  promotes  an  ideal  environment  for  osteoinduction. As  a  hydrophilic  material,
silicon  nitride  attracts  protein  cells  and  nutrients  that  stimulate  osteoprogenitor  cells  to  differentiate  into  osteoblasts, which  are
needed for optimal bone growth environments. Our silicon nitride has an inherent surface chemistry that is more similar to bone than
PEEK and metals. These properties are highlighted in an in vivo study, where we measured the force required to separate devices
from the spine after being implanted for three months, which indicates the level of osteointegration. In the absence of bacteria, the
force required to separate our silicon nitride from its surrounding bone was approximately three times that of PEEK, and nearly two
times that of titanium. In the presence of bacteria, the force required to separate our silicon nitride from its surrounding bone was
over  five  times  that  of  titanium,  while  there  was  effectively  no  separation force  required  for  PEEK,  indicating  essentially  no
osteointegration.

● Hard, Strong  and  Resistant  to  Fracture. Our  silicon  nitride  is  hard,  strong  and  possesses  superior  resistance  to  fracture  over
traditional ceramics and greater strength than polymers currently on the market. For example, our silicon nitride’s flexural strength
is  more  than  five  times  that  of  PEEK  and  our  silicon  nitride’s  compressive  strength  is  over  twenty times  that  of  PEEK.  Unlike
PEEK  interbody  spinal  fusion  devices,  we  believe  our  silicon  nitride  interbody  spinal  fusion  devices can  withstand  the  forces
exerted during implantation and daily activities over the long term.

● Antibacterial. We have demonstrated in  in vitro  and in vivo studies that silicon nitride has inherent antibacterial properties, which
reduce the risk of infection in and around a silicon nitride device. PEEK, traditional ceramics, metals and bone do not have inherent
antibacterial characteristics. These properties were highlighted in an in vitro  study  (Acta  Biomater. 2012  Dec;8(12):4447-54.  doi:
10.1016/j.actbio.2012.07.038.  Epub  2012  Jul  31.),  where  live  bacteria  counts  were  between  8  and 30  times  lower  on  our  silicon
nitride  than  PEEK  and  up  to  8  times  lower  on  our  silicon  nitride  than  titanium.  In  addition to  improving  patient  outcomes,  we
believe the antibacterial properties of our silicon nitride should make it an attractive biomaterial to hospitals and surgeons who are
not reimbursed by third-party payors for the treatment of hospital-acquired infections. Additionally, silicon nitride is synthetic and,
therefore,  there  is  a  lower  risk  of  disease  transmission  through cross-contamination  or  of  an  adverse  auto-immune  response,
sometimes associated with the use of allograft bone.

● Imaging Compatible. Our silicon nitride interbody spinal fusion devices are semi-radiolucent, clearly visible in X-rays, and produce
no  distortion  under  MRI  and  no  scattering  under  CT.  These  characteristics  enable  an  exact  view  of  the  device  for  precise  intra-
operative placement and post-operative bone fusion assessment in spinal fusion procedures. These qualities provide surgeons with
greater certainty of outcomes with our silicon nitride devices than with other biomaterials, such as PEEK and metals.

● Resistant to Wear. We believe our silicon nitride joint implant product candidates could have higher resistance to wear than metal-
on-cross-linked polyethylene  and  traditional  oxide  ceramic-on-cross-linked  polyethylene  joint  implants,  the  two  most  commonly
used  total  hip replacement  implants.  Wear  debris  associated  with  metal  implants  increases  the  risk  of  metal  sensitivity  and
metallosis. It is a primary reason for early failures of metal and polymer articulating joint components.

● Non-Corrosive. Our  silicon  nitride  does  not  have  the  drawbacks  associated  with  the  corrosive  nature  of  metal  within  the  body,
including metal sensitivity and metallosis, nor does it result in the release of metal ions into the body. As a result, we believe our
silicon nitride products will have lower revision rates and fewer complications than comparable metal and traditional oxide ceramic
products.

Our Forms of Silicon Nitride

The  chemical  composition  of  our  in-house  formulation  of  silicon  nitride  and  our  processing  and  manufacturing  experience  allow  us  to
produce silicon nitride in four distinct forms. This capability provides us with the ability to utilize our silicon nitride biomaterial in a variety
of  ways  depending  on  the  intended  application,  which,  together  with  our  silicon  nitride’s  key  characteristics,  distinguishes  us  from
manufacturers of products using other biomaterials.

We currently produce silicon nitride for use in our commercial products and product candidates in the following forms:

● Solid Silicon Nitride.  This  form  of  silicon  nitride  is  a  fully  dense,  load-bearing  solid  used  for  devices  that  require  high strength,
toughness,  fracture  resistance  and  low  wear,  including  interbody  spinal  fusion  devices,  hip  and  knee  replacement implants,  and
dental implants.

● Porous Silicon Nitride. While this form of silicon nitride has a chemical composition that is identical to that of our monolithic solid
silicon nitride, this formulation has a porous structure, which is engineered to mimic cancellous bone, the spongy bone tissue that
typically makes up the interior of human bones. Our porous silicon nitride has interconnected pores ranging in size between about
90 and 600 microns, which is similar to that of cancellous bone. This form of silicon nitride can be used for the promotion of bone
in-growth and attachment. We believe our porous silicon nitride can act as a substitute for the  orthobiologics currently used to fill
interbody devices in an effort to stimulate fusion, as a bone void filler, and as a porous scaffold for medical devices.

● Composite Silicon  Nitride. This  form  of  silicon  nitride  is  a  combination,  or  composite,  of  our  solid  monolithic  and  porous
formulations of silicon nitride. This composite may be used to manufacture devices and implants that mimic the structure of natural
bone by incorporating both a fully dense, load-bearing solid component on the outside and a porous component intended to promote
bone in-growth on the inside. This composite form of silicon nitride is used in interbody spinal fusion devices and can be used in
components for total hip and knee replacement implants.

● Silicon Nitride Coating. With a similar chemical composition as our other forms of silicon nitride, this form of silicon nitride can be
applied as an adherent coating to metallic substrates, including cobalt-chromium, titanium and steel alloys. We believe applying an
extremely  thin  layer  of  silicon  nitride  as  a  coating  may  provide  a  highly  wear-resistant  articulation  surface, such  as  on  femoral
heads, which may reduce problems associated with metal or polymer wear debris. We also believe that the  silicon nitride coating
can be applied to devices that require firm fixation and functional connections between the device or implant and the surrounding
tissue, such as hip stems and screws. The use of silicon nitride coating may also create an antibacterial barrier between the device
and the adjacent bone or tissue.

We believe we can use our silicon nitride technology platform to become a leading biomaterial company and have the following principal
competitive strengths:

Our Competitive Strengths

● Sole Provider of Silicon Nitride Medical Devices. We believe we are the only company that designs, develops, manufactures and
sells medical grade silicon nitride-based products. Due to its key characteristics, we believe our silicon nitride enables us to offer
new  and  transformative  products  across  multiple  medical  specialties.  In  addition,  with  the  FDA  clearance  of  our silicon  nitride
Valeo  products,  we  are  the  only  company  to  develop  and  manufacture  a  ceramic  for  use  in  FDA  cleared  spinal  fusion  medical
devices in the United States.

● In-House Manufacturing Capabilities. We operate a 30,000 square foot manufacturing facility located at our corporate headquarters
in  Salt  Lake  City,  Utah.  This  operation  complies  with  the  FDA’s  quality  system  regulation,  or  QSR,  and  is  certified  under  the
International  Organization  for  Standardization’s,  or  ISO,  standard  13485  for  medical  devices.  This  facility  allows  us  to  rapidly
design and produce silicon nitride products, while controlling the entire manufacturing process from raw material to finished goods.

● Established Commercial Infrastructure. We market and sell our products to surgeons and hospitals in the United States and select
markets in  Europe  and  South America  through  our  established  network  of  more  than  50  independent  sales  distributors  who  are
managed by our experienced in-house sales and marketing management team. Our control over the sales and marketing processes
also  allows us greater flexibility to selectively collaborate with distributors when we believe their experience or geographic reach
can be beneficial to us.

● Portfolio of Non-Silicon Nitride Products. In addition to designing, developing, manufacturing and commercializing silicon nitride
interbody spinal fusion devices, we sell a complementary line of non-silicon nitride spinal fixation products. We offer a full suite of
spinal fusion solutions, which increases our access to surgeons and hospitals, and allows us to more effectively market our silicon
nitride  spinal  fusion  products  to  our  customers.  Product  revenue  from  the  sale  of  these  non-silicon  nitride products  also  supports
further development of our silicon nitride products and product candidates.

● Highly Experienced  Management  and  Surgeon  Advisory  Team.  Members  of  our  management  team  have  experience  in  product
development, launching  of  new  products  into  the  orthopedics  market  and  selling  to  hospitals  through  direct  sales  organizations,
distributors, manufacturers and other orthopedic companies. We also collaborate with a network of leading surgeon advisors in the
design, development and use of our silicon nitride products and product candidates.

Our Strategy

Our goal is to become a leading biomaterial company focused on using our silicon nitride technology platform to develop, manufacture and
commercialize a broad range of medical devices. Key elements of our strategy to achieve this goal are the following:

● Drive Further  Adoption  of  our  Silicon  Nitride  Interbody  Spinal  Fusion  Devices. We  believe  that  increasing  the  awareness  of  our
silicon nitride technology by educating surgeons about its key benefits, and the design improvements to our silicon nitride products
and related instruments will accelerate the adoption of our products and ultimately help improve patient outcomes. To drive further
awareness of our products and the associated benefits offered by our silicon nitride technology, we will continue to educate surgeons
through multiple channels, including industry conferences and meetings, media outlets and through our sales and marketing efforts.

● Continue Establishing  and  Cultivating  OEM  and  Private  Label  Partnerships. Because  we  believe  silicon  nitride  is  a  superior
platform and technology for application in the spine, total joint, dental, and extremities markets, we have established, and will seek
to  establish,  additional  partnerships  with  other  medical  device  companies  to  replace  their  inferior  materials  and  products with
products manufactured from silicon nitride. For example, under an OEM arrangement, we would manufacture the company’s spinal
fusion  implant  designs  with  silicon  nitride  and  leverage  their  existing  instrumentation,  allowing  the  company  to  convert their
existing line of spinal fusion devices with limited capital expenditures. Additionally, a private label arrangement  would allow our
partners  to  sell Amedica’s  Valeo  line  of  silicon  nitride  interbody  spinal  fusion  devises  under  their  own  brand  name.  The  private
label agreements typically provide a quicker pathway to revenue as compared to the OEM arrangements.

● Enhance our Commercial Infrastructure. We expect to increase the productivity of our sales and marketing team by continuing to
engage experienced independent sales distributors with strong orthopedic surgeon relationships. For example, we have a sales agent
agreement with a Brazilian medical device distributor to distribute our Valeo line of silicon nitride interbody implants. We may also
establish distribution collaborations in the United States and abroad when access to large or well-established sales  and  marketing
organizations may help us gain access to new markets, increase sales in our existing markets, or accelerate market penetration for
selected products.

● Develop Silicon Nitride for Total Joint Components. We are incorporating our silicon nitride technology into silicon nitride-coated
metal components and solid silicon nitride components for use in total hip and knee replacement product candidates that we plan to
develop in collaboration with a strategic partner. We are also working with the FDA to define the regulatory pathway  required for
development and commercialization of these components.

● Apply our Silicon Nitride Technology Platform to Other OEM Opportunities. Our silicon nitride technology platform is adaptable
and  we  believe  it  may  be  used  to  develop  products  to  address  other  significant  opportunities,  such  as  in  the  dental,  extremities,
sports  medicine,  cardiovascular  and  trauma  markets.  We  have  manufactured  prototypes  of  dental  implants,  extremities,  sports
medicine  and  trauma  products,  and  have  developed  a  process  to  coat  metals  with  our  silicon  nitride  to  enhance  current  medical
devices and instruments. We plan to collaborate with other companies to develop and commercialize future products in these areas.

Spinal Fusion Products and Product Candidates

Our Valeo Silicon Nitride Products and Product Candidates

Our  first  generation  Valeo  silicon  nitride  spinal  fusion  device  received  510(k)  regulatory  clearance  and  a  CE  mark  in  2008.  Based  on
surgeon feedback for our first generation spinal fusion devices, we developed a second generation of Valeo products. In 2012, we received
510(k) clearance to market this second generation family of Valeo interbody spinal fusion devices which we launched with a select number
of  surgeons  in  2013.  Our  second  generation  Valeo  interbody  spinal  fusion  devices  offer  distinct  improvements  over  the  first  generation.
The  instrumentation  of  the  second  generation  devices  allow  for  better  control  of  the  device  during  implantation.  The  device  allows  for
improved stability and potentially improved fusion after implantation and is offered in a broad selection of sizes. We completed the full
launch  of  our  second  generation AL,  PL,  OL  and  TL  Valeo  interbody  spinal  fusion  devices  in  the  United  States  in  2014,  our  second
generation LL Valeo interbody spinal fusion devices in August 2015 and our second generation C Valeo interbody spinal fusion devices in
February 2016.

Our current products are:

In 2009, we received a CE Mark to commercialize the Valeo interbody spinal fusion devices made from our composite silicon nitride. The
porous silicon nitride center of these devices is designed to facilitate bone growth into the device, which we believe will allow surgeons to
reduce  or  eliminate  the  use  of  allograft  bone  and  other  osteoconductive  biomaterials.  We  are  currently  marketing  these  devices  in  the
Europe  and  Australia.  Additionally,  we  conducted  a  prospective  clinical  trial  in  Europe,  named  CASCADE,  comparing  our  Valeo
composite silicon nitride interbody devices to PEEK interbody devices filled with autograft bone to obtain additional safety and efficacy
data  to  support  a  510(k)  clearance  in  the  United  States.  The  CASCADE  study  enrolled  104  patients  in  a  prospective  clinical  trial  that
independently scored fusion rates and clinical outcomes at 12 and 24 months follow-up. Neck Disability Index scores decreased similarly in
both patient groups, consistent with clinical improvements reported in the literature. Importantly, the incidence of cervical spine fusion was
statistically  identical  between  study  groups,  and  consistent  with  figures  reported  in  other  studies.  In  March  2018,  the  FDA  cleared  our
510(k)  premarket  application  to  commercialize  a  composite  silicon  nitride  implant  which  we  refer  to  as  our  Valeo  C+CsC  with  Lumen
Interbody  Fusion  Device.  The  Valeo  C+CsC  with  Lumen  Interbody  Fusion  Device  is  a  composite  spinal  fusion  implant  that  combines
different densities of our proprietary medical grade silicon nitride ceramic. An outer shell of solid silicon nitride is manufactured around a
porous core, called CsC (Cancellous structured Ceramic). The Valeo C+CsC device is already used in Europe, and the Valeo C+CsC with
Lumen is the introduction of this porous technology in the US.

Our Non-Silicon Nitride Spinal Fixation Products

We  sell  a  line  of  complementary  non-silicon  nitride  spinal  fixation  products  to  provide  surgeons  and  hospitals  with  a  broader  range  of
products.  Product  revenue  from  the  sale  of  our  non-silicon  nitride  spinal  fixation  products  further  supports  development  of  our  silicon
nitride products and product candidates. In November 2016 the FDA notified the company that the new pedicle screw system, which we
refer  to  as  our  Taurus™  Pedicle  Screw  System,  was  cleared  for  commercialization.  The  Taurus  Pedicle  Screw  System  is  intended  to
immobilize and stabilize the spinal segments to supplement fusion of the lumbar and/or sacral spine. Taurus™ is a modular degenerative
system, connecting strength with intra-operative flexibility. The Taurus™ modular screw can be attached in-situ facilitating screw-to-screw
distraction,  improving  disc  space  visualization.  The  dual-lead  screw  design  maintains  a  rapid  insertion  speed,  while  improving  screw
pullout strength. Additionally, the tension head-body holds its position at any angle, and the patented helical flange technology eliminates
head splay and cross-threading.

Our Total Hip and Knee Joint Replacement Product Candidates

Our Total Hip Implant Product Candidates

We  have  developed  a  femoral  head  that  is  made  from  our  solid  silicon  nitride,  which  could  be  used  for  total  hip  replacement  product
candidates. This femoral head is expected to articulate against a cross-linked polyethylene liner fixed into a metal acetabular cup. Together
with a strategic partner, we have initiated biomechanical testing of our solid silicon nitride femoral heads. The final results of this test will
be  released  in  2018.  If  the  tests  indicate  that  silicon  nitride  femoral  heads  are  superior  in  terms  of  wear  performance,  taper  corrosion,
strength  and in vitro  hydrothermal  stability,  we  eventually  intend  to  commercialize  this  product  in  cooperation  with  a  strategic  partner.
However, clearance of these types of devices by the FDA will be required. Currently, the FDA has indicated that a limited one to two year
clinical trial may be necessary to obtain clearance. If clearance is eventually obtained, we intend to commercially launch products for use in
total hip replacement in 2020 or 2021.

Our Total Knee Implant Product Candidates

We have developed a femoral condyle design made from our solid silicon nitride. The femoral condyle component will attach to the lower
end of the femur. The femoral condyle is expected to articulate against a cross-linked polyethylene tibial insert that will attach to the tibial
tray  at  the  upper  end  of  the  tibia,  which  we  expect  will  be  made  from  metal.  We  have  successfully  made  prototypes  of  this  design.
Following  the  potential  clearance  of  the  femoral  head  components  (discussed  above),  we  intend  to  initiate  biomechanical  testing  with  a
strategic partner for silicon nitride components for use in knee replacement procedures to support a 510(k) submission to the FDA. If this
clearance is eventually obtained, we intend to commercialize our products for use in total knee replacement surgeries post-FDA clearance.

Other Product Opportunities

Our  silicon  nitride  technology  platform  is  adaptable  and  we  believe  it  may  be  used  to  develop  products  to  address  other  significant
opportunities, such as in the dental, extremities, sports medicine and trauma markets.

14

 
 
 
 
 
 
 
 
 
 
 
 
 
We have entered into a joint development agreement with a dental implant design company and distributor of dental technologies for the
development of a silicon nitride based dental implant system and devices.

We also believe our coating technology may be used to enhance our marketed metal products as well as other commercially available metal
spinal fusion and joint replacement products. We have produced feasibility prototypes of dental implants, other components for use in total
hip  implants  in  addition  to  our  total  hip  and  knee  implant  product  candidates  discussed  above,  a  suture  anchor  for  sports  medicine
applications,  an  osteotomy  wedge  for  extremities  applications,  and  prototypes  of  silicon  nitride-coated  plates  for  potential  trauma
applications. We have also developed a process to apply our silicon nitride as a coating on other biomaterials.

The FDA has not evaluated any of these potential products and we are not currently advancing the development of any of these product
candidates.  We  plan  to  collaborate  with  medical  device  companies  to  complete  the  development  of  and  commercialize  any  product
candidates we advance in these areas or develop any one of them ourselves if sufficient resources should become available.

Supporting Data

We and a number of independent third parties have conducted extensive biocompatibility, biomechanical,  in vivo and in vitro testing on our
silicon nitride composition to establish its safety and efficacy in support of regulatory clearance of our biomaterial, products and product
candidates.  We  have  also  completed  additional  testing  of  our  silicon  nitride  products  and  product  candidates.  The  results  of  this  testing
have been published in peer reviewed publications. We believe our product development strategy is consistent with the manner in which
other biomaterials have been successfully introduced into the market and adopted as the standard of care. Listed below is an overview of
some of the key testing completed on our silicon nitride biomaterial, products and product candidates to date, as well as other information
about our silicon nitride and other biomaterials.

Biocompatibility

Before our silicon nitride was cleared by the FDA in 2008, we conducted a series of biocompatibility tests following the guidelines of the
FDA and ISO and submitted the results to the FDA as part of the regulatory clearance process. These tests confirmed that our silicon nitride
products meet required biocompatibility standards for human use.

Promotion of Bone Growth

In  2012,  we  conducted  two  separate  studies  at  Brown  University,  the  results  of  which  suggest  that  the  chemistry  and  inherent  surface
topography of our solid silicon nitride provides an optimal environment for bone growth onto and around the device.

The first study was a series of in vitro analyses of protein adsorption, or presence on the surface of the biomaterial, onto silicon nitride,
PEEK  and  titanium.  The  results  of  this  study  indicated  that  adsorption  of  two  key  proteins  necessary  for  bone  growth  (fibronectin  and
vitronectin)  were  up  to  eight  times  greater  on  our  silicon  nitride  than  on  PEEK,  and  up  to  four  times  greater  than  on  titanium. A  third
important protein (laminin) had up to two times greater adsorption on our silicon nitride than on PEEK, and up to two-and-one-half times
greater adsorption than on titanium.

The second study was an in vivo investigation of the osteointegration characteristics of these same three biomaterials after they had been
surgically  implanted  into  the  skulls  of  laboratory  rats.  This  study  included  an  examination  of  the  effect  of  Staphylococcus  epidermidis
bacteria on osteointegration. At time intervals of up to three months after implantation of the biomaterial, the amount of new bone growth
within the surgical site and in direct contact with the implanted biomaterial was evaluated. In the absence of bacteria, new bone formation
within  the  surgical  site  surrounding  our  silicon  nitride  was  approximately  69%,  compared  with  36%  and  24%  for  titanium  and  PEEK,
respectively.  Similarly,  bone  in  direct  contact,  or  apposition,  with  our  silicon  nitride,  titanium  and  PEEK  was  59%,  19%  and  8%,
respectively. As is common, in the presence of bacteria, new bone formation within the surgical site was suppressed, but still significantly
greater  for  our  silicon  nitride  than  for  the  other  two  biomaterials.  Observed  new  bone  growth  within  the  surgical  site  surrounding  our
silicon nitride was 41%, compared with 26% and 21% for titanium and PEEK, respectively. At the implant interface, the bone apposition
for our silicon nitride, titanium and PEEK was 23%, 9% and 5%, respectively. To further characterize the extent of osteointegration, the
force  needed  to  separate  each  implant  from  its  surrounding  bone  was  measured.  A  larger  force  needed  to  separate  the  implant  is  an
indication of improved osteointegration. At three months after implantation, in the absence of bacteria, the force required to separate our
silicon nitride from its surrounding bone was approximately three times that of PEEK, and nearly two times that of titanium. In the presence
of  bacteria,  there  was  effectively  no  separation  force  required  for  PEEK,  indicating  essentially  no  osteointegration.  Our  silicon  nitride
required over five times the force to separate it from its surrounding bone in the presence of bacteria in comparison to titanium.

In 2008, we conducted an animal study in which we evaluated the level of osteointegration of our porous silicon nitride with a knee-defect
model in adult sheep. At three months after implantation, three out of five of the silicon nitride implants had extensive new bone formation
at and into the implant surface, showing that the bone had grown into our porous silicon nitride to a depth of 3 millimeters, or mm. This
animal study demonstrated the rapid osteointegration potential of our porous silicon nitride composition.

Hardness, Strength and Resistance to Fracture

Comparative Information

As shown in the table of comparative information publicly available about various biomaterials below:

● the hardness,  or  a  material’s  resistance  to  deformity,  of  silicon  nitride  is  comparable  to  traditional  ceramics,  but  is  substantially

higher than either polymers or metals;

● the strength of silicon nitride is comparable or higher than metals and traditional ceramics, and is about sixteen to fifty-five times

stronger than highly-cross-linked polyethylene, and four to eight times stronger than PEEK; and

● silicon nitride  has  the  highest  fracture  resistance  of  any  medical  ceramic  material  and  is  three  to  eleven  times  more  resistant  to
fracture than PEEK or highly-cross-linked polyethylene. This is due to the interwoven microstructure of silicon nitride. Metals have
the highest fracture resistance.

(1) GPa is a giga-pascal. Pascals are a measure of pressure. MPam1/2 is mega-pascal times a square root meter and is a measure related to

the energy required to initiate fracture of a material.

We believe that the combination of high hardness, strength and fracture resistance positions our silicon nitride as an ideal biomaterial for
many medical applications.

Burst Strength

In 2006, we conducted in-house comparative “burst strength” tests on femoral heads made from our silicon nitride produced by a contract
manufacturer to our specifications and femoral heads made from one of the strongest commercially available ceramics, BIOLOX®  delta
(zirconia-toughened alumina). These tests were performed on three designs of 28 mm femoral heads using accepted testing protocols. The
tests involved applying a load to each femoral head while mounted on a cobalt-chromium simulated hip implant stem, until the head burst.
This enabled us to directly compare the strength of the femoral heads made of the two biomaterials. The results also provided an indication
of each biomaterial’s resistance to fracture. The results of these tests are shown in the chart below.

The average burst test strength for the silicon nitride femoral heads in these tests was 75 kilonewtons, or kNs, compared with 65 kN for
BIOLOX® delta, or about a 15% improvement. The burst strengths observed in our tests for BIOLOX® delta femoral heads are comparable
to  those  observed  by  an  independent  party  testing  the  same  design  BIOLOX®  delta  femoral  heads  as  we  did.  We  also  conducted  burst
strength tests of 36 mm femoral heads made from our silicon nitride which showed those femoral heads had burst strengths that averaged
164 kN.

Resistance to Wear

In 2011, we commissioned an independent laboratory to conduct a wear study using our silicon nitride femoral heads. We tested our 28 mm
silicon  nitride  femoral  heads  articulated  against  cross-linked  polyethylene  acetabular  liners  and  our  40  mm  silicon  nitride  femoral  heads
articulated  against  cross-linked  polyethylene  acetabular  liners  using  well-established  protocols  in  a  hip  simulator  for  their  wear
performance  over  5  million  cycles.  We  then  compared  the  results  for  our  silicon  nitride  product  candidates  to  the  results  for  the  cobalt
chrome femoral head and publicly available data from other commonly paired products. The results and comparison showed that:

● our silicon nitride-on-cross-linked polyethylene had approximately half the wear rate of that publicly reported for cobalt chrome-on-

cross-linked polyethylene articulating hip components; and

● our silicon  nitride-on-cross-linked  polyethylene  had  comparable  wear  to  that  publicly  reported  for  traditional  oxide  ceramic-on-

cross-linked polyethylene articulating hip components.

Antibacterial Properties

The  results  of  the  two  studies  at  Brown  University  in  2012,  demonstrate  that  our  solid  silicon  nitride  has  antibacterial  properties.  The
objective of the in vitro study was to determine how our silicon nitride, PEEK and titanium interact with bacteria, protein and bone cells
without the use of antibiotics and compared the growth of five different types of bacteria on silicon nitride, PEEK and titanium over time.
Live bacteria counts were between 8 to 30 times lower on silicon nitride than PEEK and up to 8 times lower on silicon nitride than titanium.

In  the in vivo  study,  bacteria  were  applied  to  the  biomaterials  before  implantation.  Three  months  after  implantation,  no  infection  was
observed  with  silicon  nitride,  whereas  both  PEEK  and  titanium  showed  infection.  The  data  demonstrate  that  our  silicon  nitride  inhibits
biofilm formation and bacterial colonization around the biomaterial.

Imaging Compatibility

In 2007, we conducted a study to compare the imaging characteristics of test blanks made of PEEK, the metals titanium and tantalum, and
silicon nitride using a cadaver human vertebral body. Images of the vertebral body and the blanks were obtained using X-ray, CT and MRI
under identical conditions. We assessed the radiolucent characteristics of the blanks in X-ray images quantitatively, assessed the presence
of scatter in CT qualitatively and assessed distortion in MRI quantitatively. In X-ray, the metal blanks did not permit visualization of the
underlying bone of the vertebral body, while PEEK was transparent, rendering its location difficult to determine. The silicon nitride blank
had an intermediate radiolucency that rendered it visible and allowed a visual assessment of the underlying bone of the vertebral body. CT
and MRI of the metal blanks indicated the presence of distortion while silicon nitride and PEEK exhibited no scattering.

Sales and Marketing

We market and sell our products to surgeons and hospitals through our established network of more than 50 independent sales distributors
who are managed by our experienced in-house sales and marketing management team. Our sales efforts to-date have been in the United
States and select markets in Europe and South America. To supplement our independent sales distributors, in select international markets,
such as Europe, China, Japan, Australia, Latin America and Canada, we may also seek to establish collaborations with leading orthopedic
companies  where  we  believe  that  a  large,  well-established  partner  may  provide  better  access  to  those  markets.  For  example,  we  have
entered into a distribution agreement with a Brazilian medical device distributor for distribution of our Valeo line of products in Brazil, are
looking for an appropriate distribution partner in Australia, and we are working with strategic partners in China and Japan to gain approval
of  our  products  for  commercialization  in  those  countries.  In  addition,  we  may  establish  collaborations  in  the  United  States  under
circumstances  where  access  to  a  larger  sales  and  marketing  organization  may  help  to  expand  the  market  or  accelerate  penetration  for
selected products.

In  addition  to  leveraging  the  strong  existing  surgeon  relationships  of  our  distribution  network,  we  market  our  products  through  a
combination  of  initiatives  that  are  designed  to  establish  and  increase  awareness  of  our  silicon  nitride  products  and  their  benefits  over
alternative  products.  We  attend  and  make  presentations  at  major  industry  events,  including  society  meetings,  to  educate  surgeons  and
distributors about our products and product candidates. We advertise in trade journals and publications, and offer unique pricing strategies,
including  product  bundling  and  incentivizing  our  distribution  network  to  create  and  maintain  long-term  relationships  with  surgeons  and
hospitals. We also use surgeon advisors to assist in product development and to help implement awareness campaigns aimed at educating
surgeons about our products. As part of these campaigns, we provide educational materials for hospitals and surgeons. We also conduct
regional  training  seminars  where  our  product  managers,  trainers,  engineers,  sales  and  marketing  staff  members  work  together  with  our
surgeon advisors to educate surgeons and our distribution network in the use of our products.

Original Equipment Manufacturing and Private Label

In addition to the markets into which we directly sell our products, we are utilizing our silicon nitride technology platform to expand our
current penetration in the spinal fusion market through original equipment manufacturer (“OEM”) and private label partnerships. We also
expect to do the same in other markets such as total hip and knee joint replacements, dental, extremities, and sports medicine. We believe
our biomaterial expertise, strong intellectual property and formulaic manufacturing process will allow us to transition currently available
medical device products made of inferior biomaterials and manufacture them using silicon nitride and our technology platform to improve
their characteristics.

Silicon Nitride Manufacturing

Manufacturing

To  control  the  quality,  cost  and  availability  of  our  silicon  nitride  products  and  product  candidates,  we  operate  our  own  manufacturing
facility. Our 54,000 square foot corporate building includes a 30,000 square foot ISO 13485 certified medical device manufacturing space.
It is equipped with state-of-the-art powder processing, spray drying, pressing and computerized machining equipment, sintering furnaces,
and  other  testing  equipment  that  enables  us  to  control  the  entire  manufacturing  process  for  our  silicon  nitride  products  and  product
candidates. To our knowledge, we are the only vertically integrated silicon nitride orthopedic medical device manufacturer in the world. All
operations with the exceptions of raw material production, cleaning, packaging and sterilization are performed in-house. We purchase raw
materials, consisting of silicon nitride ceramic powder and dopant chemical compounds, from several vendors which are ISO registered and
approved by us. These raw materials are characterized and tested in our facility in accordance with our specifications and then blended to
formulate our silicon nitride. We believe that there are multiple vendors that can supply us these raw materials and we continually monitor
the quality and pricing offered by our vendors to ensure high quality and cost-effective supply of these materials.

18

 
 
 
 
 
 
 
 
 
 
 
 
Non-Silicon Nitride and Instruments Manufacturing

We obtain our non-silicon nitride spinal fixation products and instruments from third-party manufacturers. We also plan to rely on third-
party manufacturers for the supply of the metal components of our silicon nitride hip and knee joint replacement product candidates. We
only use manufacturers that operate under QSR and are ISO 13485 certified. Our in-house quality control group examines subcontracted
components to ensure that they meet our required specifications. We believe that the use of third-party sources for non-silicon nitride spinal
fixation products and instruments will reduce our capital investment requirements and allow us to strategically focus our resources on the
manufacture of our silicon nitride products and product candidates.

Intellectual Property

We rely on a combination of patents, trademarks, trade secrets, nondisclosure agreements, proprietary information ownership agreements
and  other  intellectual  property  measures  to  protect  our  intellectual  property  rights.  We  believe  that  in  order  to  have  a  competitive
advantage, we must continue to develop and maintain the proprietary aspects of our technologies.

As of March 27, 2018, we had 58 issued U.S. patents, 5 pending U.S. patent applications, 1 pending PCT application, 6 granted foreign
patents and 1 pending foreign patent applications. Our first issued patent expired in 2016, with the last of these patents expiring in 2034.
The first core patents do not expire until 2022; these include US 6,881,229 and US 6,790,233.

We  have  fourteen  U.S.  patents  and  one  pending  U.S.  patent  application  directed  to  articulating  implants  using  our  high-strength,  high
toughness doped silicon nitride solid ceramic. The issued patents, which include US 6,881,229; US 7,666,229; US 7,758,646; US 7,695,521;
US 7,771,481; US 7,776,085; US 7,780,738; US 8,016,890; US 8,123,812; US 8,133,284, US 8,377,134; US 8,747,540; US 9,051,639; US
9,517,136;  begin  to  expire  in  2022.  The  pending  U.S.  patent  application  has  been  assigned  serial  no.  15/162,363  and  a  non-final  Office
action was issued January 25, 2018.

We  also  have  six  U.S.  patents  and  five  foreign  patent  (Switzerland,  Germany,  France,  Greece  and  the  Netherlands)  related  to  our  CSC
technology  that  are  directed  to  implants  that  have  both  a  dense  load-bearing,  or  cortical,  component  and  a  porous,  or  cancellous,
component, together with a surface coating. These issued patents, which include US 6,790,233; US 6,846,327; US 7,695,521; US 8,133,284;
US  8,747,408;  US  9,649,197;  and  EP  1389978,  begin  to  expire  in  2022.  EP  1389978  was  registered  in  Switzerland,  Germany,  France,
Greece and the Netherlands.

We  also  have  three  U.S.  patents  that  we  acquired  in  July  2012  from  Dytech  Corporation  Ltd.,  or  Dytech,  directed  to  manufacturing
processes for the production of porous ceramics for use in our orthopedic implants. These patents include US 5,563,106 and US 5,705,448,
which have now expired; these patents also include US 6,617,270, which expires in 2019. Under our acquisition agreement with Dytech,
Dytech granted to us a perpetual, irrevocable and exclusive license, including the right to grant sublicenses, to certain improvements and
know-how related to the acquired patents. In return, we are required to pay Dytech a low single-digit royalty on net sales of products sold
by us, our affiliates, or our licensees that are covered by one or more valid claims of these patents, and a percentage of any non-royalty
licensing income we may receive in the event we grant a license to others.

19

 
 
 
 
 
 
 
 
 
 
 
 
Our remaining issued patents and pending applications are directed to additional aspects of our products and technologies including, among
other things:

● designs for pedicle screws;

● designs for intervertebral fusion devices;

● designs for hip implants; and

● designs for knee implants.

We  also  expect  to  rely  on  trade  secrets,  know-how,  continuing  technological  innovation  and  in-licensing  opportunities  to  develop  and
maintain  our  intellectual  property  position.  However,  trade  secrets  are  difficult  to  protect.  We  seek  to  protect  the  trade  secrets  in  our
proprietary  technology  and  processes,  in  part,  by  entering  into  confidentiality  agreements  with  commercial  partners,  collaborators,
employees, consultants, scientific advisors and other contractors and into invention assignment agreements with our employees and some of
our  commercial  partners  and  consultants.  These  agreements  are  designed  to  protect  our  proprietary  information  and,  in  the  case  of  the
invention assignment agreements, to grant us ownership of the technologies that are developed.

Competition

The main alternatives to our silicon nitride biomaterial include: PEEK, which is predominantly manufactured by Invibio; BIOLOX®  delta,
which is a traditional oxide ceramic manufactured by CeramTec; allograft bone; metals; and coated metals.

We believe our main competitors in the orthopedic implant market, which utilize a variety of competitive biomaterials, include: Medtronic,
Inc.;  DePuy  Synthes  Companies,  a  group  of  Johnson  &  Johnson  companies;  Stryker  Corporation;  Biomet,  Inc.;  Zimmer  Holdings,  Inc.;
Smith & Nephew plc; and Aesculap Inc. Presently, these companies buy ceramic components on an OEM basis from manufacturers such as
CeramTec,  Kyocera  and  CoorTek,  Inc.,  among  others.  We  anticipate  that  these  and  other  orthopedic  companies  and  OEMs  will  seek  to
introduce new biomaterials and products that compete with ours.

Competition within the industry is primarily based on technology, innovation, product quality, and product awareness and acceptance by
surgeons. Our principal competitors have substantially greater financial, technical and marketing resources, as well as significantly greater
manufacturing capabilities than we do, and they may succeed in developing products that render our implants and product candidates non-
competitive. Our ability to compete successfully will depend upon our ability to develop innovative products with advanced performance
features based on our silicon nitride technologies.

Government Regulation of Medical Devices

Governmental authorities in the United States, at the federal, state and local levels, and other countries extensively regulate, among other
things, the research, development, testing, manufacture, labeling, promotion, advertising, distribution, marketing and export and import of
products such as those we are commercializing and developing. Failure to obtain approval or clearance to market our products and products
under  development  and  to  meet  the  ongoing  requirements  of  these  regulatory  authorities  could  prevent  us  from  continuing  to  market  or
develop our products and product candidates.

United States

Pre-Marketing Regulation

In  the  United  States,  medical  devices  are  regulated  by  the  FDA.  Unless  an  exemption  applies,  a  new  medical  device  will  require  either
prior  510(k)  clearance  or  approval  of  a  premarket  approval  application,  or  PMA,  before  it  can  be  marketed  in  the  United  States.  The
information that must be submitted to the FDA in order to obtain clearance or approval to market a new medical device varies depending on
how  the  medical  device  is  classified  by  the  FDA.  Medical  devices  are  classified  into  one  of  three  classes  on  the  basis  of  the  controls
deemed  by  the  FDA  to  be  necessary  to  reasonably  ensure  their  safety  and  effectiveness.  Class  I  devices,  which  are  those  that  have  the
lowest level or risk associated with them, are subject to general controls, including labeling, premarket notification and adherence to the
QSR. Class II devices are subject to general controls and special controls, including performance standards. Class III devices, which have
the  highest  level  of  risk  associated  with  them,  are  subject  to  most  of  the  previously  identified  requirements  as  well  as  to  premarket
approval. Most Class I devices and some Class II devices are exempt from the 510(k) requirement, although manufacturers of these devices
are still subject to registration, listing, labeling and QSR requirements.

A 510(k) premarket notification must demonstrate that the device in question is substantially equivalent to another legally marketed device,
or predicate device, that did not require premarket approval. In evaluating the 510(k), the FDA will determine whether the device has the
same intended use as the predicate device, and (a) has the same technological characteristics as the predicate device, or (b) has different
technological characteristics, and (i) the data supporting the substantial equivalence contains information, including appropriate clinical or
scientific data, if deemed necessary by the FDA, that demonstrates that the device is as safe and as effective as a legally marketed device,
and (ii) does not raise different questions of safety and effectiveness than the predicate device. Most 510(k)s do not require clinical data for
clearance, but the FDA may request such data. The FDA’s goal is to review and act on each 510(k) within 90 days of submission, but it
may take longer based on requests for additional information. In addition, requests for additional data, including clinical data, will increase
the time necessary to review the notice. If the FDA does not agree that the new device is substantially equivalent to the predicate device,
the new device will be classified in Class III, and the manufacturer must submit a PMA. Since July 2012, however, with the enactment of
the  Food  and  Drug Administration  Safety  and  Innovation Act,  or  FDASIA,  a  de  novo  pathway  is  directly  available  for  certain  low  to
moderate  risk  devices  that  do  not  qualify  for  the  510(k)  pathway  due  to  lack  of  a  predicate  device.  Modifications  to  a  510(k)-cleared
medical device may require the submission of another 510(k) or a PMA if the changes could significantly affect the safety or effectiveness
or constitute a major change in the intended use of the device.

Modifications  to  a  510(k)-cleared  device  frequently  require  the  submission  of  a  traditional  510(k),  but  modifications  meeting  certain
conditions may be candidates for FDA review under a Special 510(k). If a device modification requires the submission of a 510(k), but the
modification  does  not  affect  the  intended  use  of  the  device  or  alter  the  fundamental  scientific  technology  of  the  device,  then  summary
information  that  results  from  the  design  control  process  associated  with  the  cleared  device  can  serve  as  the  basis  for  clearing  the
application. A  Special  510(k)  allows  a  manufacturer  to  declare  conformance  to  design  controls  without  providing  new  data.  When  the
modification  involves  a  change  in  material,  the  nature  of  the  “new”  material  will  determine  whether  a  traditional  or  Special  510(k)  is
necessary. For example, in its Device Advice on How to Prepare a Special 510(k), the FDA uses the example of a change in a material in a
finger joint prosthesis from a known metal alloy to a ceramic that has not been used in a legally marketed predicate device as a type of
change  that  should  not  be  submitted  as  a  Special  510(k).  However,  if  the  “new”  material  is  a  type  that  has  been  used  in  other  legally
marketed devices within the same classification for the same intended use, a Special 510(k) is appropriate. The FDA gives as an example a
manufacturer  of  a  hip  implant  who  changes  from  one  alloy  to  another  that  has  been  used  in  another  legally  marketed  predicate.  Special
510(k)s are typically processed within 30 days of receipt.

The  PMA  process  is  more  complex,  costly  and  time  consuming  than  the  510(k)  clearance  procedure. A  PMA  must  be  supported  by
extensive data including, but not limited to, technical, preclinical, clinical, manufacturing, control and labeling information to demonstrate
to the FDA’s satisfaction the safety and effectiveness of the device for its intended use. After a PMA is submitted, the FDA has 45 days to
determine whether it is sufficiently complete to permit a substantive review. If the PMA is complete, the FDA will file the PMA. The FDA
is subject to performance goal review times for PMAs and may issue a decision letter as a first action on a PMA within 180 days of filing,
but if it has questions, it will likely issue a first major deficiency letter within 150 days of filing. It may also refer the PMA to an FDA
advisory panel for additional review, and will conduct a preapproval inspection of the manufacturing facility to ensure compliance with the
QSR,  either  of  which  could  extend  the  180-day  response  target.  While  the  FDA’s  ability  to  meet  its  performance  goals  has  generally
improved during the past few years, it may not meet these goals in the future. A PMA can take several years to complete and there is no
assurance that any submitted PMA will ever be approved. Even when approved, the FDA may limit the indication for which the medical
device may be marketed or to whom it may be sold. In addition, the FDA may request additional information or request the performance of
additional clinical trials before it will reconsider the approval of the PMA or as a condition of approval, in which case the trials must be
completed after the PMA is approved. Changes to the device, including changes to its manufacturing process, may require the approval of a
supplemental PMA.

21

 
 
 
 
 
 
 
If  a  medical  device  is  determined  to  present  a  “significant  risk,”  the  manufacturer  may  not  begin  a  clinical  trial  until  it  submits  an
investigational  device  exemption,  or  IDE,  to  the  FDA  and  obtains  approval  of  the  IDE  from  the  FDA.  The  IDE  must  be  supported  by
appropriate data, such as animal and laboratory testing results and include a proposed clinical protocol. These clinical trials are also subject
to the review, approval and oversight of an institutional review board, or IRB, which is an independent and multi-disciplinary committee of
volunteers who review and approve research proposals, and the reporting of adverse events and experiences, at each institution at which
the clinical trial will be performed. The clinical trials must be conducted in accordance with applicable regulations, including but not limited
to the FDA’s IDE regulations and current good clinical practices. A clinical trial may be suspended by the FDA, the IRB or the sponsor at
any time for various reasons, including a belief that  the  risks  to  the  study  participants  outweigh  the  benefits  of  participation  in  the  trial.
Even if a clinical trial is completed, the results may not demonstrate the safety and efficacy of a device, or may be equivocal or otherwise
not be sufficient to obtain approval.

Post-Marketing Regulation

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

● compliance with  the  QSR,  which  require  manufacturers  to  follow  stringent  design,  testing,  control,  documentation,  record
maintenance, including  maintenance  of  complaint  and  related  investigation  files,  and  other  quality  assurance  controls  during  the
manufacturing process;

● labeling regulations,  which  prohibit  the  promotion  of  products  for  uncleared  or  unapproved  or  “off-label”  uses  and  impose other

restrictions on labeling; and

● medical device reporting obligations, which require that manufacturers investigate and report to the FDA adverse events, including
deaths, or serious injuries that may have been or were caused by a medical device and malfunctions in the device that would likely
cause or contribute to a death or serious injury if it were to recur.

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

● warning letters;

● fines, injunctions, and civil penalties;

● recall or seizure of our products;

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

● refusal to grant 510(k) clearance or PMA approvals of new products;

● withdrawal of 510(k) clearance or PMA approvals; and

● criminal prosecution.

To  ensure  compliance  with  regulatory  requirements,  medical  device  manufacturers  are  subject  to  market  surveillance  and  periodic,  pre-
scheduled and unannounced inspections by the FDA, and these inspections may include the manufacturing facilities of our subcontractors.

International Regulation

International sales of medical devices are subject to foreign government regulations, which vary substantially from country to country. The
time required to obtain approval by a foreign country may be longer or shorter than that required for FDA approval, and the requirements
may differ. For example, the primary regulatory authority with respect to medical devices in Europe is that of the European Union. The
European Union consists of 28 countries and has a total population of over 500 million people. The unification of these countries into a
common  market  has  resulted  in  the  unification  of  laws,  standards  and  procedures  across  these  countries,  which  may  expedite  the
introduction of medical devices like those we are offering and developing. Norway, Iceland, Lichtenstein and Switzerland are not members
of the European Union, but have transposed applicable European medical device laws into their national legislation. Thus, a device that is
marketed in the European Union may also be recognized and accepted in those four non-member European countries as well.

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  relevant  directives  will  be  entitled  to  bear  CE
Conformity Marking, indicating that the device conforms to the essential requirements of the applicable directives and, accordingly, can be
commercially distributed throughout the European Union. Actual implementation of these directives, however, may vary on a country-by-
country basis. The CE Mark is a mandatory conformity mark on medical devices distributed and sold in the European Union and certifies
that a medical device has met applicable requirements.

The method of assessing conformity varies, but normally involves a combination of self-assessment by the manufacturer and a third-party
assessment  by  a  “Notified  Body.”  Notified  Bodies  are  independent  testing  houses,  laboratories,  or  product  certifiers  authorized  by  the
European Union member states to perform the required conformity assessment tasks, such as quality system audits and device compliance
testing. An assessment by a Notified Body based within the European Union is required in order for a manufacturer to distribute the product
commercially throughout the European Union. Medium and higher risk devices require the intervention of a Notified Body which will be
responsible for auditing the manufacturer’s quality system. The Notified Body will also determine whether or not the product conforms to
the  requirements  of  the  applicable  directives.  Devices  that  meet  the  applicable  requirements  of  E.U.  law  and  have  undergone  the
appropriate conformity assessment routes will be granted CE “certification.” The CE Mark is mandatory for medical devices sold not only
within the countries of the European Union but more generally within most of Europe. As many of the European standards are converging
with international standards, the CE Mark is often used on medical devices manufactured and sold outside of Europe (notably in Asia that
exports many manufactured products to Europe). CE Marking gives companies easier access into not only the European market but also to
Asian  and  Latin  American  markets,  most  of  whom  recognize  the  CE  Mark  on  medical  device  as  a  mark  of  quality  and  adhering  to
international standards of consumer safety, health or environmental requirements.

Compliance with Healthcare Laws

We must comply with various U.S. federal and state laws, rules and regulations pertaining to healthcare fraud and abuse, including anti-
kickback and false claims laws, rules, and regulations, as well as other healthcare laws in connection with the commercialization of our
products. Fraud and abuse laws are interpreted broadly and enforced aggressively by various state and federal agencies, including the U.S.
Department of Justice, the U.S. Office of Inspector General for the Department of Health and Human Services and various state agencies.

We have entered into agreements with certain surgeons for assistance with the design of our products, some of whom we anticipate may
make referrals to us or order our products. A majority of these agreements contain provisions for the payments of royalties. In addition,
some surgeons currently own shares of our stock. We have structured these transactions with the intention of complying with all applicable
laws, including fraud and abuse, data privacy and security, and transparency laws. Despite this intention, there can be no assurance that a
particular  government  agency  or  court  would  determine  our  practices  to  be  in  full  compliance  with  such  laws.  We  could  be  materially
impacted if regulatory or enforcement agencies or courts interpret our financial arrangements with surgeons to be in violation of healthcare
laws, including, without limitation, fraud and abuse, data privacy and security, or transparency laws.

The U.S. federal Anti-Kickback Statute prohibits persons, including a medical device manufacturer (or a party acting on its behalf), from
knowingly or willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in exchange for or to induce either the
referral of an individual for a service or product or the purchasing, ordering, arranging for, or recommending the ordering of, any service or
product for which payment may be made by Medicare, Medicaid or any other federal healthcare program. This statute has been interpreted
to  apply  to  arrangements  between  medical  device  manufacturers  on  one  hand  and  healthcare  providers  on  the  other.  The  term
“remuneration” is not defined in the federal Anti-Kickback Statute and has been broadly interpreted to include anything of value, such as
cash payments, gifts or gift certificates, discounts, waiver of payments, credit arrangements, ownership interests, the furnishing of services,
supplies or equipment, and the provision of anything at less than its fair market value. Courts have broadly interpreted the scope of the law,
holding  that  it  may  be  violated  if  merely  “one  purpose”  of  an  arrangement  is  to  induce  referrals,  irrespective  of  the  existence  of  other
legitimate  purposes.  The Anti-Kickback  Statute  prohibits  many  arrangements  and  practices  that  are  lawful  in  businesses  outside  of  the
healthcare  industry.  Although  there  are  a  number  of  statutory  exemptions  and  regulatory  safe  harbors  protecting  certain  business
arrangements from prosecution, the exemptions and safe harbors are drawn narrowly, and practices that involve remuneration intended to
induce  prescribing,  purchasing  or  recommending  may  be  subject  to  scrutiny  if  they  do  not  qualify  for  an  exemption  or  safe  harbor.  Our
practices may not in all cases meet all of the criteria for safe harbor protection from federal Anti-Kickback Statute liability. The reach of the
Anti-Kickback Statute was broadened by the recently enacted Patient Protection and Affordable Care Act of 2010 and the Health Care and
Education Affordability Reconciliation Act of 2010, collectively, the Affordable Care Act or ACA, which, among other things, amends the
intent requirement of the federal Anti-Kickback Statute such that a person or entity no longer needs to have actual knowledge of the statute
or specific intent to violate it in order to have committed a violation. In addition, the ACA provides that the government may assert that a
claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for
purposes of the federal False Claims Act (discussed below) or the civil monetary penalties statute, which imposes fines against any person
who is determined to have presented or caused to be presented claims to a federal healthcare program that the person knows or should know
is for an item or service that was not provided as claimed or is false or fraudulent. In addition to the federal Anti-Kickback Statute, many
states  have  their  own  anti-kickback  laws.  Often,  these  laws  closely  follow  the  language  of  the  federal  law,  although  they  do  not  always
have the same scope, exceptions, safe harbors or sanctions. In some states, these anti-kickback laws apply not only to payments made by
government healthcare programs but also to payments made by other third-party payors, including commercial insurance companies.

Sales, marketing, consulting, and advisory arrangements between medical device manufacturers and sales agents and physicians are subject
to  the Anti-Kickback  Statute  and  other  fraud  and  abuse  laws.  Government  officials  have  focused  recent  enforcement  efforts  on,  among
other things, the sales and marketing activities of healthcare companies, including medical device manufacturers, and have brought cases
against individuals or entities whose personnel allegedly offered unlawful inducements to potential or existing customers in an attempt to
procure their business. We expect these activities to continue to be a focus of government enforcement efforts. Settlements of these cases by
healthcare companies have involved significant fines and penalties and in some instances criminal plea agreements. We are also aware of
governmental investigations of some of the largest orthopedic device companies reportedly focusing on consulting and service agreements
between these companies and orthopedic surgeons. These developments are ongoing and we cannot predict the effects they will have on
our business.

The federal False Claims Act imposes liability on any person that, among other things, knowingly presents, or causes to be presented, a
false  or  fraudulent  claim  for  payment  by  a  federal  healthcare  program.  The  qui  tam  provisions  of  the  False  Claims Act  allow  a  private
individual to bring civil actions on behalf of the federal government alleging that the defendant has submitted a false claim, or has caused
such a claim to be submitted, to the federal government, and to share in any monetary recovery. There are many potential bases for liability
under the False Claims Act. Liability arises, primarily, when a person knowingly submits, or causes another to submit, a false claim for
reimbursement to the federal government. The False Claims Act has been used to assert liability on the basis of inadequate care, kickbacks,
and other improper referrals, and allegations as to misrepresentations with respect to the services rendered. Qui tam actions have increased
significantly  in  recent  years,  causing  greater  numbers  of  healthcare  companies,  including  medical  device  manufacturers,  to  defend  false
claim  actions,  pay  damages  and  penalties,  or  be  excluded  from  participation  in  Medicare,  Medicaid  or  other  federal  or  state  healthcare
programs  as  a  result  of  investigations  arising  out  of  such  actions.  In  addition,  various  states  have  enacted  similar  laws  analogous  to  the
False Claims Act. Many of these state laws apply where a claim is submitted to any third-party payor and not merely a federal healthcare
program. We are unable to predict whether we would be subject to actions under the False Claims Act or a similar state law, or the impact
of  such  actions.  However,  the  cost  of  defending  such  claims,  as  well  as  any  sanctions  imposed,  could  adversely  affect  our  financial
performance.  The  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  also  created  several  new  federal  crimes,
including healthcare fraud and false statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and willfully
executing a scheme to defraud any healthcare benefit program, including private third party payors. 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.

24

 
 
 
 
 
 
 
In addition, we may be subject to, or our marketing or research activities may be limited by, data privacy and security regulation by both
the federal government and the states in which we conduct our business. For example, HIPAA and its implementing regulations established
uniform  federal  standards  for  certain  “covered  entities”  (healthcare  providers,  health  plans  and  healthcare  clearinghouses)  governing  the
conduct of certain electronic healthcare transactions and protecting the security and privacy of protected health information. The American
Recovery and Reinvestment Act of 2009, commonly referred to as the economic stimulus package, included expansion of HIPAA’s privacy
and  security  standards  called  the  Health  Information  Technology  for  Economic  and  Clinical  Health  Act,  or  HITECH,  which  became
effective  on  February  17,  2010.  Among  other  things,  HITECH  makes  HIPAA’s  privacy  and  security  standards  directly  applicable  to
“business  associates”—independent  contractors  or  agents  of  covered  entities  that  create,  receive,  maintain,  or  transmit  protected  health
information  in  connection  with  providing  a  service  for  or  on  behalf  of  a  covered  entity.  HITECH  also  increased  the  civil  and  criminal
penalties  that  may  be  imposed  against  covered  entities,  business  associates  and  possibly  other  persons,  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. These laws also require the reporting of breaches of protected health information to
affected  individuals,  regulators  and  in  some  cases,  local  or  national  media.  HIPAA  and  HITECH  impose  strict  limits  on  our  physician
collaborators’ ability to use and disclose patient information on our behalf.

There are also an increasing number of state “sunshine” laws that require manufacturers to provide reports to state governments on pricing
and  marketing  information.  Several  states  have  enacted  legislation  requiring  medical  device  companies  to,  among  other  things,  establish
marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales and marketing activities, and
to prohibit or limit certain other sales and marketing practices. In addition, a federal law known as the Physician Payments Sunshine Act,
now  requires  medical  device  manufacturers  to  track  and  report  to  the  federal  government  certain  payments  and  other  transfers  of  value
made to physicians and teaching hospitals and ownership or investment interests held by physicians and their immediate family members.
The first reporting period covered only payments or transfers of value made and ownership or investment interests held by physicians and
their immediate family members from August 1, 2013 to December 31, 2013. The federal government disclosed the reported information
on a publicly available website beginning in September 2014. For calendar year 2014, the Physician Payments Sunshine Act will require
medical device manufacturers to report payments and transfers of values made and ownership or investment interests held by physicians
and their immediate family members for the full calendar year. These laws may adversely affect our sales, marketing, and other activities
by imposing administrative and compliance burdens on us. If we fail to track and report as required by these laws or to otherwise comply
with these laws, we could be subject to the penalty provisions of the pertinent state and federal authorities.

Clinical  research  is  heavily  regulated  by  FDA  regulations  for  the  protection  of  human  subjects  (21  C.F.R.  50  and  56)  and  also  the
regulations  of  the  U.S  Department  of  Health  and  Human  Services,  or  the  Common  Rule  (45  C.F.R  46).  Both  FDA  human  subject
regulations and the Common Rule impose restrictions on the involvement of human subjects in clinical research and require, among other
things, the balancing of the risks and benefits of research, the documented informed consent of research participants, initial and ongoing
review  of  research  by  an  IRB.  Similar  regulations  govern  research  conducted  in  foreign  countries.  Compliance  with  human  subject
protection regulations is costly and time consuming. Failure to comply could substantially and adversely impact our research program and
the development of our products.

Because of the breadth of these laws and the narrowness of available statutory and regulatory exemptions, it is possible that some of our
business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of the
federal and state laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including
criminal  and  significant  civil  monetary  penalties,  damages,  fines,  imprisonment,  exclusion  from  participation  in  government  healthcare
programs, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product
clearances and approvals, private “qui tam” actions brought by individual whistleblowers in the name of the government or refusal to allow
us to enter into supply contracts, including government contracts, and the curtailment or restructuring of our operations. Public disclosure
of privacy and data security violations could cause significant reputational harm. Any of these events could adversely affect our ability to
operate our business and our results of operations. To the extent that any of our products are sold in a foreign country, we may be subject to
similar  foreign  laws  and  regulations,  which  may  include,  for  instance,  applicable  post-marketing  requirements,  including  safety
surveillance,  anti-fraud  and  abuse  laws,  implementation  of  corporate  compliance  programs,  as  well  as  laws  and  regulations  requiring
transparency  of  pricing  and  marketing  information  and  governing  the  privacy  and  security  of  health  information,  such  as  the  E.U.’s
Directive 95/46 on the Protection of Individuals with regard to the Processing of Personal Data, or the Data Directive, and the wide variety
of national laws implementing the Data Directive.

25

 
 
 
 
 
 
 
 
Healthcare Reform

The regulations we are subject to may change as result of legislative and regulatory healthcare reform.

Significant healthcare reform was enacted in 2010 when the Patient Protection and Affordable Care Act or the PPACA, was signed into
law.  State  laws  also  were  enacted  to  implement  the  PPACA.  While  a  primary  goal  of  these  healthcare  reform  efforts  was  to  expand
coverage  to  more  individuals,  it  also  involved  increased  government  price  controls,  additional  regulatory  mandates  and  other  measures
designed to constrain medical costs. The PPACA significantly impacts the medical device industry. Among other things, 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, which began on January 1, 2013, but was suspended during 2016 and 2017 and has been suspended for 2018 and 2019;

● 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; and

● 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 healthcare services through bundled payment models.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. For example, on January 2, 2013,
former  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, 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.  Moreover,  certain  legislative
changes  to  and  regulatory  changes  under  the  PPACA  have  occurred  in  the  115th  United  States  Congress  and  under  the  Trump
Administration.  For  example,  on  December  22,  2017,  President  Trump  signed  a  budget  reconciliation  act  into  law,  which  among  other
things, repealed the penalty for individuals who do not maintain minimum essential coverage, which was a central component of PPACA’s
approach  to  expanding  coverage.  On  January  9,  2018,  President  Trump  signed  the  Bipartisan  Budget Act  of  2018,  which,  among  other
things, repealed the PPACA provision establishing an independent payment advisory board that would have submitted recommendations to
reduce Medicare spending if projected Medicare spending exceeded a specified growth rate.

Additional  legislative  changes  to  and  regulatory  changes  under  the  PPACA  remain  possible.  We  expect  that  other  state  and  federal
healthcare  reform  measures  will  be  adopted  in  the  future,  any  of  which  could  reduce  the  number  of  patients  with  coverage  or  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.

Third-Party Reimbursement

Because we typically receive payment directly from hospitals and surgical centers, we do not anticipate relying directly on payment for any
of our products from third-party payors, such as Medicare, Medicaid, private insurers, and managed care companies. However, our business
will be affected by policies administered by federal and state healthcare programs, such as Medicare and Medicaid, as well as private third-
party  payors,  which  often  follow  the  policies  of  the  state  and  federal  healthcare  programs.  For  example,  our  business  will  be  indirectly
impacted by the ability of a hospital or medical facility to obtain coverage and third-party reimbursement for procedures performed using
our  products.  Many  hospitals  and  clinics  in  the  United  States  belong  to  group  purchasing  organizations  (that  typically  incentivize  their
hospital  members  to  make  a  relatively  large  proportion  of  purchases  from  a  limited  number  of  vendors  of  similar  products  that  have
contracted  to  offer  discounted  prices).  Such  contracts  often  include  exceptions  for  purchasing  certain  innovative  new  technologies,
however. Accordingly, the commercial success of our products may also depend to some extent on our ability to either negotiate favorable
purchase contracts with key group purchasing organizations or persuade hospitals and clinics to purchase our product “off contract.” These
third-party payors may deny reimbursement if they determine that a device used in a procedure was not medically necessary; was not used
in accordance with cost-effective treatment methods, as determined by the third-party payor; or was used for an unapproved use. A national
or local coverage decision denying Medicare coverage for one or more of our products could result in private insurers and other third party
payors also denying coverage. Even if favorable coverage and reimbursement status is attained for our products, less favorable coverage
policies and reimbursement rates may be implemented in the future. The cost containment measures that third-party payors and providers
are instituting, both within the United States and abroad, could significantly reduce our potential revenues from the sale of our products
and any product candidates. We cannot provide any assurances that we will be able to obtain and maintain third party coverage or adequate
reimbursement for our products and product candidates in whole or in part.

For inpatient and outpatient procedures, including those that will involve use of our products, Medicare and many other third-party payors
in the United States reimburse hospitals at a prospectively determined amount. This amount is generally based on one or more diagnosis
related  groups,  or  DRGs,  associated  with  the  patient’s  condition  for  inpatient  treatment  and  generally  based  on  ambulatory  payment
classifications,  or APCs,  associated  with  the  procedures  performed  as  an  outpatient  at  an  ambulation  surgicenter.  Each  DRG  or APC  is
associated with a level of payment and may be adjusted from time to time, usually annually. Prospective payments are intended to cover
most  of  the  non-physician  hospital  costs  incurred  in  connection  with  the  applicable  diagnosis  and  related  procedures.  Implant  products,
such  as  those  we  plan  to  sell,  represent  part  of  the  total  procedure  costs  while  labor,  hospital  room  and  board,  and  other  supplies  and
services  represent  the  balance  of  those  costs.  However,  the  prospective  payment  amounts  are  typically  set  independently  of  a  particular
hospital’s actual costs associated with treating a particular patient and implanting a device. Therefore, the payment that a hospital would
receive for a particular hospital visit would not typically take into account the cost of our products.

Medicare has established a number of DRGs for inpatient procedures that involve the use of products similar to ours. Although Medicare
has  authority  to  create  special  DRGs  for  hospital  services  that  more  properly  reflect  the  actual  costs  of  expensive  or  new-technology
devices implanted as part of a procedure, it has declined to do so in the past, and we do not expect that it will do so with respect to our
current products and product candidates. Medicare’s DRG and APC classifications may have implications outside of Medicare, as many
other U.S. third-party payors often use Medicare DRGs and APCs for purposes of determining reimbursement.

We  believe  that  orthopedic  implants  generally  have  been  well  received  by  third-party  payors  because  of  the  ability  of  these  implants  to
greatly reduce long-term healthcare costs for patients with degenerative joint disease. However, coverage and reimbursement policies vary
from payor to payor and are subject to change. As discussed above, hospitals that purchase medical devices for treatment of their patients
generally  rely  on  third-party  payors  to  reimburse  all  or  part  of  the  costs  and  fees  associated  with  the  procedures  performed  with  these
devices.  Both  government  and  private  third-party  coverage  and  reimbursement  levels  are  critical  to  new  product  acceptance.  Neither
hospitals nor surgeons are likely to use our products if they do not receive reimbursement for the procedures adequate to cover the cost of
our products.

While it is expected that hospitals will be able to obtain coverage for procedures using our products, the level of payment available to them
for  such  procedures  may  change  over  time.  State  and  federal  healthcare  programs,  such  as  Medicare  and  Medicaid,  closely  regulate
provider payment levels and have sought to contain, and sometimes reduce, payment levels. Commercial insurers and managed care plans
frequently follow government payment policies, and are likewise interested in controlling increases in the cost of medical care. These third-
party payors may deny payment if they determine that a procedure was not medically necessary, a device used in a procedure was not used
in accordance with cost-effective treatment methods, as determined by the third-party payor, or was used for an unapproved use.

27

 
 
 
 
 
 
 
 
 
 
In  addition,  some  payors  are  adopting  pay-for-performance  programs  that  differentiate  payments  to  healthcare  providers  based  on  the
achievement  of  documented  quality-of-care  metrics,  cost  efficiencies,  or  patient  outcomes.  These  programs  are  intended  to  provide
incentives to providers to find ways to deliver the same or better results while consuming fewer resources. As a result of these programs,
and  related  payor  efforts  to  reduce  payment  levels,  hospitals  and  other  providers  are  seeking  ways  to  reduce  their  costs,  including  the
amounts they pay to medical device suppliers. Adverse changes in payment rates by payors to hospitals could adversely impact our ability
to market and sell our products and negatively affect our financial performance.

In  international  markets,  healthcare  payment  systems  vary  significantly  by  country  and  many  countries  have  instituted  price  ceilings  on
specific  product  lines.  There  can  be  no  assurance  that  our  products  will  be  considered  cost-effective  by  third-party  payors,  that
reimbursement will be available or, if available, that the third-party payors’ reimbursement policies will not adversely affect our ability to
sell our products profitably.

Member countries of the European Union offer various combinations of centrally financed healthcare systems and private health insurance
systems. The relative importance of government and private systems varies from country to country. Governments may influence the price
of medical devices through their pricing and reimbursement rules and control of national healthcare systems that fund a large part of the
cost of those products to consumers. Some jurisdictions operate positive and negative list systems under which products may be marketed
only once a reimbursement price has been agreed upon. Some of these countries may require, as condition of obtaining reimbursement or
pricing approval, the completion of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available
therapies.  Some  E.U.  member  states  allow  companies  to  fix  their  own  prices  for  devices,  but  monitor  and  control  company  profits.  The
choice of devices is subject to constraints imposed by the availability of funds within the purchasing institution. Medical devices are most
commonly sold to hospitals or healthcare facilities at a price set by negotiation between the buyer and the seller. A contract to purchase
products  may  result  from  an  individual  initiative  or  as  a  result  of  a  competitive  bidding  process.  In  either  case,  the  purchaser  pays  the
supplier, and payment terms vary widely throughout the European Union. Failure to obtain favorable negotiated prices with hospitals or
healthcare facilities could adversely affect sales of our products.

Employees

As of March 1, 2018, we had 33 employees. We believe that our success will depend, in part, on our ability to attract and retain qualified
personnel. We have never experienced a work stoppage due to labor difficulties and believe that our relations with our employees are good.
None of our employees are represented by labor unions.

ITEM 1A. RISK FACTORS

In addition to the other information contained in this Annual Report, the following risk factors should be considered carefully in evaluating
our company. Our business, financial condition, liquidity or results of operations could be materially adversely affected by any of these
risks.

Risks Related to Our Business and Strategy

We  have  incurred  net  losses  since  our  inception  and  anticipate  that  we  will  continue  to  incur  substantial  net  losses  for  the
foreseeable future. We may never achieve or sustain profitability.

We have incurred substantial net losses since our inception. For the years ended December 31, 2017 and 2016 we incurred a net loss of
$9.3  million  and  $14.8  million,  respectively,  and  used  cash  in  operations  of  $4.8  million  and  $7.2  million,  respectively.  We  have  an
accumulated deficit of $220.6 million at December 31, 2017. Our losses have resulted principally from costs incurred in connection with
our  sales  and  marketing  activities,  research  and  development  activities,  manufacturing  activities,  general  and  administrative  expenses
associated with our operations, impairments on intangible assets and property and equipment, interest expense, loss on extinguishment of
debt  and  offering  costs.  Even  if  we  are  successful  in  launching  additional  products  into  the  market,  we  expect  to  continue  to  incur
substantial  losses  for  the  foreseeable  future  as  we  continue  to  sell  and  market  our  current  products  and  research  and  develop,  and  seek
regulatory approvals for, our product candidates.

28

 
 
 
 
 
 
 
 
 
 
 
 
 
 
If sales revenue from any of our current products or product candidates that receive marketing clearance from the FDA or other regulatory
body  is  insufficient,  if  we  are  unable  to  develop  and  commercialize  any  of  our  product  candidates,  or  if  our  product  development  is
delayed, we may never become profitable. Even if we do become profitable, we may be unable to sustain or increase our profitability on a
quarterly or annual basis.

Our success depends on our ability to successfully commercialize silicon nitride-based medical devices, which to date have experienced
only limited market acceptance.

We  believe  we  are  the  first  and  only  company  to  use  silicon  nitride  in  medical  applications.  To  date,  however,  we  have  had  limited
acceptance  of  our  silicon  nitride-based  products  and  our  product  revenue  has  been  derived  substantially  from  our  non-silicon  nitride
products. In order to succeed in our goal of becoming a leading biomaterial technology company utilizing silicon nitride, we must increase
market awareness of our silicon nitride interbody spinal fusion products, continue to implement our sales and marketing strategy, enhance
our commercial infrastructure and commercialize our silicon nitride joint replacement components and other products. If we fail in any of
these endeavors or experience delays in pursuing them, we will not generate revenues as planned and will need to curtail operations or seek
additional financing earlier than otherwise anticipated.

Our  current  products  and  our  future  products  may  not  be  accepted  by  hospitals  and  surgeons  and  may  not  become  commercially
successful.

Although we received 510(k) regulatory clearance from the FDA for our first silicon nitride spinal fusion products in 2008, we have not
been  able  to  obtain  significant  market  share  of  the  interbody  spinal  fusion  market  to  date,  and  may  not  obtain  such  market  share  in  the
future. Even if we receive regulatory clearances or approvals for our product candidates in development, these product candidates may not
gain market acceptance among orthopedic surgeons and the medical community. Orthopedic surgeons may elect not to use our products for
a variety of reasons, including:

● lack or perceived lack of evidence supporting the beneficial characteristics of our silicon nitride technology;

● limited long-term data on the use of silicon nitride in medical devices;

● lower than expected clinical benefits in comparison with other products;

● the perception by surgeons that there are insufficient advantages of our products relative to currently available products;

● hospitals may choose not to purchase our products;

● group purchasing  organizations  may  choose  not  to  contract  for  our  products,  thus  limiting  availability  of  our  products  to

hospital purchasers;

● the price of our products, which may be higher than products made of the other commonly used biomaterials in the interbody

spinal fusion market and total joint market;

● lack of  coverage  or  adequate  payment  from  managed  care  plans  and  other  third-party  payers  for  the  procedures  that  use  our

products;

● Medicare, Medicaid or other third-party payers may limit or not permit reimbursement for procedures using our products;

● ineffective marketing and distribution support;

● the time  and  resources  that  may  be  required  for  training,  or  the  inadequate  training,  of  surgeons  in  the  proper  use  of  our

products;

● the development of alternative biomaterials and products that render our products less competitive or obsolete; and

● the development of or improvement of competitive products.

If surgeons do not perceive our silicon nitride products and product candidates as superior alternatives to competing products, we will
not be able to generate significant revenues, if any.

Even  if  surgeons  are  convinced  of  the  superior  characteristics  of  our  silicon  nitride  products  and  our  product  candidates  that  we
successfully introduce compared to the limitations of the current commonly used biomaterials, surgeons may find other methods or turn to
other  biomaterials  besides  silicon  nitride  to  overcome  such  limitations.  For  instance,  with  respect  to  interbody  spinal  fusion  products,
surgeons  or  device  manufacturers  may  use  more  effective  markers  for  enhancing  the  imaging  compatibility  of  PEEK  devices,  more
effective antibiotics to prevent or treat implant-related infections, and more effective osteoconductive and osteoinductive materials when
implanting an interbody spinal fusion device. Device manufacturers may also coat metal with existing traditional ceramics to reduce the
risk  of  metal  wear  particles  and  corrosion  in  total  joint  replacement  implants. Additionally,  surgeons  may  increase  their  use  of  metal
interbody  spinal  fusion  devices  if  there  is  an  increasing  perception  that  PEEK  devices  are  limited  by  their  strength  and  resistance  to
fracture.

If we are unable to increase the productivity of our sales and marketing infrastructure we will not be able to penetrate the spinal fusion
market.

We market and sell our products to surgeons and hospitals in the United States and select markets in Europe and South America using a
network of independent third-party distributors who have existing surgeon relationships. We manage this distribution network through our
in-house  sales  and  marketing  management  team.  We  may  also  establish  distribution  collaborations  in  the  United  States  and  abroad  in
instances  where  access  to  a  large  or  well-established  sales  and  marketing  organization  may  help  to  expand  the  market  or  accelerate
penetration for selected products.

We  cannot  assure  you  that  we  will  succeed  in  entering  into  and  maintaining  productive  arrangements  with  an  adequate  number  of
distributors  that  are  sufficiently  committed  to  selling  our  products.  The  establishment  of  a  distribution  network  is  expensive  and  time
consuming. As we launch new products and increase our marketing effort with respect to existing products, we will need to continue to
hire, train, retain and motivate skilled independent distributors with significant technical knowledge in various areas, such as spinal fusion
and total hip and knee joint replacement. In addition, the commissions we pay our distributors have increased over time, which has resulted
in higher sales and marketing expenses, and those commissions and expenses may increase in the future. Furthermore, current and potential
distributors may market and sell the products of our competitors. Even if the distributors market and sell our products, our competitors may
be able, by offering higher commission payments or other incentives, to persuade these distributors to reduce or terminate their sales and
marketing efforts related to our products. The distributors may also help competitors solicit business from our existing customers. Some of
our independent distributors account for a significant portion of our sales volume, and, if we were to lose them, our sales could be adversely
affected.

Even if we engage and maintain suitable relationships with an adequate number of distributors, they may not generate revenue as quickly as
we  expect  them  to,  commit  the  necessary  resources  to  effectively  market  and  sell  our  products,  or  ultimately  succeed  in  selling  our
products.  We  have  been  unable  to  obtain  meaningful  market  share  in  the  interbody  spinal  fusion  device  market  with  our  current  silicon
nitride  products  to  date  and  we  may  not  be  successful  in  increasing  the  productivity  of  our  sales  and  marketing  team  and  distribution
network to gain meaningful market share for our silicon nitride products, which could adversely affect our business and financial condition.

The  orthopedic  market  is  highly  competitive  and  we  may  not  be  able  to  compete  effectively  against  the  larger,  well-established
companies that dominate this market or emerging and small innovative companies that may seek to obtain or increase their share of the
market.

The markets for spinal fusions and total hip and knee implant products are intensely competitive, and many of our competitors are much
larger and have substantially more financial and human resources than we do. Many have long histories and strong reputations within the
industry,  and  a  relatively  small  number  of  companies  dominate  these  markets.  Medtronic,  Inc.;  DePuy  Synthes  Companies,  a  group  of
Johnson  &  Johnson  companies;  Stryker  Corporation;  Biomet,  Inc.;  Zimmer  Holdings,  Inc.;  and  Smith  &  Nephew  plc,  account  for  a
significant amount of orthopedic sales worldwide.

These companies enjoy significant competitive advantages over us, including:

● broad product offerings, which address the needs of orthopedic surgeons and hospitals in a wide range of procedures;

● products that are supported by long-term clinical data;

● greater experience in, and resources for, launching, marketing, distributing and selling products, including strong sales forces

and established distribution networks;

● existing relationships with spine and joint reconstruction surgeons;

● extensive intellectual property portfolios and greater resources for patent protection;

● greater financial and other resources for product research and development;

● greater experience in obtaining and maintaining FDA and other regulatory clearances and approvals for products and product

enhancements;

● established manufacturing operations and contract manufacturing relationships;

● significantly greater name recognition and widely recognized trademarks; and

● established relationships with healthcare providers and payers.

Our products and any product candidates that we may introduce into the market may not enable us to overcome the competitive advantages
of  these  large  and  dominant  orthopedic  companies.  In  addition,  even  if  we  successfully  introduce  additional  product  candidates
incorporating our silicon nitride biomaterial into the market, emerging and small innovative companies may seek to increase their market
share  and  they  may  eventually  possess  competitive  advantages,  which  could  adversely  impact  our  business.  Our  competitors  may  also
employ pricing strategies that could adversely affect the pricing of our products and pricing in the spinal fusion and total joint replacement
market generally.

Moreover,  many  other  companies  are  seeking  to  develop  new  biomaterials  and  products  which  may  compete  effectively  against  our
products  in  terms  of  performance  and  price.  For  example,  Smith  &  Nephew  has  developed  a  ceramic-coated  metal,  known  as  Oxinium,
which may overcome certain of the limitations of metal joint replacement products and could directly compete with our silicon nitride and
silicon nitride-coated product candidates.

We have significant customer concentration, so that economic difficulties or changes in the purchasing policies or patterns of our
key customers could have a significant impact on our business and operating results.

A small number of customers account for a substantial portion of our product revenues. Our customers are primarily hospitals and surgical
centers. At December 31, 2017 and 2016, our largest customer, Bon Secours St. Mary’s Hospital, or St. Mary’s, had a receivable balance of
approximately 12% and 16%, respectively, of our total trade accounts receivable. In addition, St. Mary’s accounted for 21 % and 18% of
our product revenues for the years ended December 31, 2017 and 2016, respectively. Sales of our products to our customers, including St.
Mary’s, are not based on long-term, committed-volume purchase contracts, and we may not continue to receive significant revenues from
St. Mary’s or any customer. Because of our significant customer concentration, our revenue could fluctuate significantly due to changes in
economic conditions, the use of competitive products, or the loss of, reduction of business with, or less favorable terms with St. Mary’s or
any of our other significant customers. A significant portion of St. Mary’s’ purchases have been of our non-silicon nitride products, so it
may  be  able  to  purchase  competitive  similar  products  from  others. A  reduction  or  delay  in  orders  from  St.  Mary’s  or  any  of  our  other
significant  customers,  or  a  delay  or  default  in  payment  by  any  significant  customer,  could  materially  harm  our  business  and  results  of
operations.

The  manufacturing  process  for  our  silicon  nitride  products  is  complex  and  requires  sophisticated  state-of-the-art  equipment,
experienced manufacturing personnel and highly specialized knowledge. If we are unable to manufacture our silicon nitride products
on a timely basis consistent with our quality standards, our results of operation will be adversely impacted.

In order to control the quality, cost and availability of our silicon nitride products, we developed our own manufacturing capabilities. We
operate  a  30,000  square  foot  manufacturing  facility  which  is  certified  under  the  ISO  13485  medical  device  manufacturing  standard  for
medical devices and operates under the FDA’s quality systems regulations, or QSRs. All operations with the exceptions of raw material
production, cleaning, packaging and sterilization are performed at this facility.

In order to mitigate the risk associated with us being the sole manufacturer of our silicon nitride medical device products, in June 2014, we
entered into a manufacturing development and supply agreement with Kyocera Industrial Ceramics Corporation, or Kyocera. We updated
our material master file and submitted a 510(k) with the FDA in the third quarter of 2014 to qualify Kyocera as a second source supplier of
our silicon nitride products. Kyocera has been qualified as a second source supplier of our silicon nitride products. Although we expect this
arrangement with Kyocera to continue, if Kyocera ceases to continue as a qualified manufacturer of these products and product candidates,
we will be the sole manufacturer of these products and will need to seek other potential secondary manufacturers. Our reliance solely on
our  internal  resources  to  manufacture  our  silicon  nitride  products  entails  risks  to  which  we  would  not  be  subject  if  we  had  secondary
suppliers for their manufacture, including:

● the inability to meet our product specifications and quality requirements consistently;

● a delay or inability to procure or expand sufficient manufacturing capacity to meet additional demand for our products;

● manufacturing and product quality issues related to the scale-up of manufacturing;

● the inability to produce a sufficient supply of our products to meet product demands;

● the disruption of our manufacturing facility due to equipment failure, natural disaster or failure to retain key personnel; and

● our inability to ensure our compliance with regulations and standards of the FDA, including QSRs, and corresponding state and

international regulatory authorities, including the CFDA.

Any of these events could lead to a reduction in our product sales, product launch delays, failure to obtain regulatory clearance or approval
or impact our ability to successfully sell our products and commercialize our products candidates.

We  depend  on  a  limited  number  of  third-party  suppliers  for  key  raw  materials  used  in  the  manufacturing  of  our  silicon  nitride
products, and the loss of these third-party suppliers or their inability to supply us with adequate raw materials could harm our business.

We rely on a limited number of third-party suppliers for the raw materials required for the production of our silicon nitride products and
product  candidates.  Our  dependence  on  a  limited  number  of  third-party  suppliers  involves  several  risks,  including  limited  control  over
pricing, availability, quality, and delivery schedules for raw materials. We have no supply agreements in place with any of our suppliers and
cannot be certain that our current suppliers will continue to provide us with the quantities of raw materials that we require or that satisfy our
anticipated  specifications  and  quality  requirements. Any  supply  interruption  in  limited  or  single  sourced  raw  materials  could  materially
harm our ability to manufacture our products until a new source of supply, if any, could be identified and qualified. We may be unable to
find a sufficient alternative supply channel within a reasonable time or on commercially reasonable terms. Any performance failure on the
part  of  our  suppliers  could  delay  the  production  of  our  silicon  nitride  products  and  product  candidates  and  delay  the  development  and
commercialization  of  our  product  candidates,  including  limiting  supplies  necessary  for  commercial  sale,  clinical  trials  and  regulatory
approvals, which could have a material adverse effect on our business.

Use  of  third-party  manufacturers  increases  the  risk  that  we  will  not  have  adequate  supplies  of  our  non-silicon  nitride  products  or
instrumentation sets.

The majority of our product revenue is currently generated by sales of non-silicon nitride products. Our reliance on a limited number of
third-party manufacturers to supply us with our non-silicon nitride products and instruments exposes us to risks that could delay our sales,
or result in higher costs or lost product revenues. In particular, our manufacturers could:

● encounter difficulties  in  achieving  volume  production,  quality  control  and  quality  assurance  or  suffer  shortages  of  qualified
personnel, which could result in their inability to manufacture sufficient quantities of our commercially available non-silicon
nitride products  to  meet  market  demand  for  those  products,  or  they  could  experience  similar  problems  that  result  in  the
manufacture of insufficient quantities of our non-silicon nitride product candidates; and

● fail to follow and remain in compliance with the FDA-mandated QSRs, compliance which is required for all medical devices, or
fail to document their compliance to QSRs, either of which could lead to significant delays in the availability of materials for
our non-silicon nitride products or instrumentation sets.

If we are unable to obtain adequate supplies of our non-silicon nitride products and related instrumentation sets that meet our specifications
and quality standards, it will be difficult for us to compete effectively. We have no supply agreements in place with our manufacturers and
they may change the terms of our future orders or choose not to supply us with products or instrumentation sets in the future. Furthermore,
if a third-party manufacturer from whom we purchase fails to perform its obligations, we may be forced to purchase products or related
instrumentation from other third-party manufacturers, which we may not be able to do on reasonable terms, if at all. In addition, if we are
required  to  change  manufacturers  for  any  reason,  we  will  be  required  to  verify  that  the  new  manufacturer  maintains  facilities  and
procedures that comply with quality standards and with all applicable regulations and guidelines. The delays associated with the verification
of a new manufacturer or the re-verification of an existing manufacturer could negatively affect our ability to produce and distribute our
non-silicon nitride products or instruments in a timely manner.

In order to be successful, we must expand our available product lines of silicon nitride-based medical devices by commercializing new
product candidates, but we may not be able to do so in a timely fashion and at expected costs, or at all.

Although we are currently marketing our silicon nitride interbody spinal fusion implants, in order to be successful, we will need to expand
our product lines to include other silicon nitride devices. Therefore, we are developing silicon nitride product candidates for total hip and
knee replacement procedures and are exploring the application of our silicon nitride technology for other potential applications. However,
we have yet to commercialize any silicon nitride products beyond our spinal fusion products. To succeed in our commercialization efforts,
we  must  effectively  continue  product  development  and  testing,  obtain  regulatory  clearances  and  approvals,  and  enhance  our  sales  and
marketing capabilities. We may also have to write down significant inventory if existing products are replaced by new products. Because
of these uncertainties, there is no assurance that we will succeed in bringing any of our current or future product candidates to market. If we
fail in bringing our product candidates to market, or experience delays in doing so, we will not generate revenues as planned and will need
to curtail operations or seek additional financing earlier than otherwise anticipated.

33

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We will depend on one or more strategic partners to develop and commercialize our total joint replacement product candidates, and if
our strategic partners are unable to execute effectively on our agreements with them, we may never become profitable.

We are seeking a strategic partner to develop and commercialize our total joint replacement product candidates. We will be reliant on our
strategic partners to develop and commercialize a total hip or knee joint replacement product candidate that utilizes silicon nitride-coated
components, although we have not yet entered into an agreement with any strategic partner to develop products with these silicon nitride-
coated components and may be unable to do so on agreeable terms. In order to succeed in our joint commercialization efforts, we and any
future partners must execute effectively on all elements of a combined business plan, including continuing to establish sales and marketing
capabilities,  manage  certified,  validated  and  effective  commercial-scale  manufacturing  operations,  conduct  product  development  and
testing, and obtain regulatory clearances and approvals for our product candidate. If we or any of our strategic partners fail in any of these
endeavors,  or  experience  delays  in  pursuing  them,  we  will  not  generate  revenues  as  planned  and  will  need  to  curtail  operations  or  seek
additional financing earlier than otherwise anticipated.

Part of our strategy is to establish and develop OEM partnerships and arrangements, which subjects us to various risks.

Because we believe silicon nitride is a superior platform and technology for application in the spine, total joint and other markets, we are
establishing OEM partnerships with other companies to replace their materials and products with silicon nitride. Sales of products to OEM
customers will expose our business to a number of risks. Sales through OEM partners could be less profitable than direct sales. Sales of our
products through multiple channels could also confuse customers and cause the sale of our products to decline. In addition, OEM customers
will  require  that  products  meet  strict  standards.  Our  compliance  with  these  requirements  could  result  in  increased  development,
manufacturing, warranty and administrative costs. A significant increase in these costs could adversely affect our operating results. If we
fail to meet OEM specifications on a timely basis, our relationships with our OEM partners may be harmed. Furthermore, we would not
control  our  OEM  partners,  and  they  could  sell  competing  products,  may  not  incorporate  our  technology  into  their  products  in  a  timely
manner and may devote insufficient sales efforts to the OEM products.

If hospitals and other healthcare providers are unable to obtain coverage or adequate reimbursement for procedures performed with
our products, it is unlikely our products will be widely used.

In the United States, the commercial success of our existing products and any future products will depend, in part, on the extent to which
governmental payers at the federal and state levels, including Medicare and Medicaid, private health insurers and other third-party payers
provide  coverage  for  and  establish  adequate  reimbursement  levels  for  procedures  utilizing  our  products.  Because  we  typically  receive
payment  directly  from  hospitals  and  surgical  centers,  we  do  not  anticipate  relying  directly  on  payment  from  third-party  payers  for  our
products. However, hospitals and other healthcare providers that purchase our orthopedic products for treatment of their patients generally
rely  on  third-party  payers  to  pay  for  all  or  part  of  the  costs  and  fees  associated  with  our  products  as  part  of  a  “bundled”  rate  for  the
associated procedures. The existence of coverage and adequate reimbursement for our products and the procedures performed with them by
government and private payers is critical to market acceptance of our existing and future products. Neither hospitals nor surgeons are likely
to use our products if they do not receive adequate reimbursement for the procedures utilizing our products.

Many  private  payers  currently  base  their  reimbursement  policies  on  the  coverage  decisions  and  payment  amounts  determined  by  the
Centers for Medicare and Medicaid Services, or CMS, which administers the Medicare program. Others may adopt different coverage or
reimbursement  policies  for  procedures  performed  with  our  products,  while  some  governmental  programs,  such  as  Medicaid,  have
reimbursement  policies  that  vary  from  state  to  state,  some  of  which  may  not  pay  for  the  procedures  performed  with  our  products  in  an
adequate amount, if at all. A Medicare national or local coverage decision denying coverage for one or more of our products could result in
private  and  other  third-party  payers  also  denying  coverage  for  our  products.  Third-party  payers  also  may  deny  reimbursement  for  our
products if they determine that a product used in a procedure was not medically necessary, was not used in accordance with cost-effective
treatment methods, as determined by the third-party payer, or was used for an unapproved use. Unfavorable coverage or reimbursement
decisions  by  government  programs  or  private  payers  underscore  the  uncertainty  that  our  products  face  in  the  market  and  could  have  a
material adverse effect on our business.

34

 
 
 
 
 
 
 
 
 
 
 
Many  hospitals  and  clinics  in  the  United  States  belong  to  group  purchasing  organizations,  which  typically  incentivize  their  hospital
members to make a relatively large proportion of purchases from a limited number of vendors of similar products that have contracted to
offer discounted prices. Such contracts often include exceptions for purchasing certain innovative new technologies, however. Accordingly,
the commercial success of our products may also depend to some extent on our ability to either negotiate favorable purchase contracts with
key group purchasing organizations and/or persuade hospitals and clinics to purchase our product “off contract.”

The  healthcare  industry  in  the  United  States  has  experienced  a  trend  toward  cost  containment  as  government  and  private  payers  seek  to
control  healthcare  costs  by  paying  service  providers  lower  rates.  While  it  is  expected  that  hospitals  will  be  able  to  obtain  coverage  for
procedures  using  our  products,  the  level  of  payment  available  to  them  for  such  procedures  may  change  over  time.  State  and  federal
healthcare programs, such as Medicare and Medicaid, closely regulate provider payment levels and have sought to contain, and sometimes
reduce, payment levels. Private payers frequently follow government payment policies and are likewise interested in controlling increases in
the  cost  of  medical  care.  In  addition,  some  payers  are  adopting  pay-for-performance  programs  that  differentiate  payments  to  healthcare
providers  based  on  the  achievement  of  documented  quality-of-care  metrics,  cost  efficiencies,  or  patient  outcomes.  These  programs  are
intended  to  provide  incentives  to  providers  to  deliver  the  same  or  better  results  while  consuming  fewer  resources. As  a  result  of  these
programs, and related payer efforts to reduce payment levels, hospitals and other providers are seeking ways to reduce their costs, including
the amounts they pay to medical device manufacturers. We may not be able to sell our implants profitably if third-party payers deny or
discontinue coverage or reduce their levels of payment below that which we project, or if our production costs increase at a greater rate than
payment levels. Adverse changes in payment rates by payers to hospitals could adversely impact our ability to market and sell our products
and negatively affect our financial performance.

In  international  markets,  medical  device  regulatory  requirements  and  healthcare  payment  systems  vary  significantly  from  country  to
country,  and  many  countries  have  instituted  price  ceilings  on  specific  product  lines.  We  cannot  assure  you  that  our  products  will  be
considered  cost-effective  by  international  third-party  payers,  that  reimbursement  will  be  available  or,  if  available,  that  the  third-party
payers’  reimbursement  policies  will  not  adversely  affect  our  ability  to  sell  our  products  profitably. Any  failure  to  receive  regulatory  or
reimbursement approvals would negatively impact market acceptance of our products in any international markets in which those approvals
are sought.

Moreover, certain legislative changes to and regulatory changes under the PPACA have occurred in the 115th United States Congress and
under the Trump Administration. For example, on December 22, 2017, President Trump signed a budget reconciliation act into law, which
among other things, repealed the penalty for individuals who do not maintain minimum essential coverage, which was a central component
of  PPACA’s  approach  to  expanding  coverage.  On  January  9,  2018,  President  Trump  signed  the  Bipartisan  Budget Act  of  2018,  which,
among  other  things,  repealed  the  PPACA  provision  establishing  an  independent  payment  advisory  board  that  would  have  submitted
recommendations  to  reduce  Medicare  spending  if  projected  Medicare  spending  exceeded  a  specified  growth  rate  we  cannot  predict  the
ultimate  content,  timing  or  effect  of  any  changes  to  the  Health  Care  Reform Act  or  other  federal  and  state  reform  efforts.  There  is  no
assurance  that  federal  or  state  healthcare  reform  will  not  adversely  affect  our  business  and  financial  results,  and  we  cannot  predict  how
future federal or state legislative, judicial or administrative changes relating to healthcare reform will affect our business.

Prolonged  negative  economic  conditions  in  domestic  and  international  markets  may  adversely  affect  us,  our  suppliers,  partners  and
consumers, and the global orthopedic market which could harm our financial position.

There is a risk that one or more of our current suppliers may not continue to operate. Any lender that is obligated to provide funding to us
under any future credit agreement with us may not be able to provide funding in a timely manner, or at all, when we require it. The cost of,
or lack of, available credit or equity financing could impact our ability to develop sufficient liquidity to maintain or grow our company.
These negative changes in domestic and international economic conditions or additional disruptions of either or both of the financial and
credit markets may also affect third-party payers and may have a material adverse effect on our business, results of operations, financial
condition and liquidity.

35

 
 
 
 
 
 
 
 
 
 
In addition, we believe that various demographics and industry-specific trends will help drive growth in the orthopedics markets, but these
demographics  and  trends  are  uncertain.  Actual  demand  for  orthopedic  products  generally,  and  our  products  in  particular,  could  be
significantly  less  than  expected  if  our  assumptions  regarding  these  factors  prove  to  be  incorrect  or  do  not  materialize,  or  if  alternative
treatments gain widespread acceptance.

We are dependent on our senior management team, engineering team, sales and marketing team and surgeon advisors, and the loss of
any  of  them  could  harm  our  business.  We  may  not  have  sufficient  personnel  to  effectuate  our  business  strategy  due  to  our  recent
reduction in force.

The members of our current senior management team have worked together in their new positions with us for a limited time and may not be
able to successfully implement our strategy. In addition, we have not entered into employment agreements, other than change-in-control
severance agreements, with any of the members of our senior management team. There are no assurances that the services of any of these
individuals will be available to us for any specified period of time. The successful integration of our senior management team, the loss of
members of our senior management team, sales and marketing team, engineering team and key surgeon advisors, or our inability to attract
or  retain  other  qualified  personnel  or  advisors  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of
operations.

In October 2016, we implemented a substantial reduction in our workforce by approximately 38% to lower operating expenses. This most
recent  restructuring  plan  and  other  such  efforts  could  result  in  disruptions  to  our  operations.  We  may  not  have  sufficient  number  of
qualified personnel to effectuate our business strategy which could have a material adverse effect on our business, financial condition and
results of operations.

If  we  experience  significant  disruptions  in  our  information  technology  systems,  our  business,  results  of  operations  and  financial
condition 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  our  sales  and  marketing,  accounting  and  financial  functions;  manufacturing  processes;  inventory;  engineering  and
product development functions; and our research and development functions. As such, our information technology systems are vulnerable
to  damage  or  interruption  including  from  earthquakes,  fires,  floods  and  other  natural  disasters;  terrorist  attacks  and  attacks  by  computer
viruses  or  hackers;  power  losses;  and  computer  systems,  or  Internet,  telecommunications  or  data  network  failures.  The  failure  of  our
information technology systems to perform as we anticipate or our failure to effectively implement new systems could disrupt our entire
operation and could result in decreased sales, increased overhead costs, excess inventory and product shortages, all of which could have a
material adverse effect on our reputation, business, results of operations and financial condition.

Risks Related to Our Capital Resources and Impairments

We  will  require  additional  financing  and  our  failure  to  obtain  additional  funding  would  force  us  to  delay,  reduce  or  eliminate  our
product development programs or commercialization efforts.

We currently have limited committed sources of capital and we have limited liquidity. Our cash and cash equivalents as of December 31,
2017 was $0.5 million. We require substantial future capital in order to continue to conduct the research and development and regulatory
clearance  and  approval  activities  necessary  to  bring  our  products  to  market,  to  establish  effective  marketing  and  sales  capabilities.  Our
existing  capital  resources  are  not  sufficient  to  enable  us  to  fund  the  completion  of  the  development  and  commercialization  of  all  of  our
product  candidates.  We  cannot  determine  with  certainty  the  duration  and  completion  costs  of  the  current  or  future  development  and
commercialization of our product candidates for spinal fusion procedures, joint replacement and coated metals or if, when, or to what extent
we will generate revenues from the commercialization and sale of any of these product candidates for which we obtain regulatory approval.
We may never succeed in achieving regulatory approval for certain or all of these product candidates. The duration, costs and timing of
clinical  trials  and  development  of  our  spinal  fusion,  joint  replacement  and  coated  metal  product  candidates  will  depend  on  a  variety  of
factors, including:

● the scope,  rate  of  progress,  and  expense  of  our  ongoing,  as  well  as  any  additional,  clinical  trials  and  other  research  and

development activities;

● future clinical trial results we may must or choose to conduct;

● potential changes in government regulation; and

● the timing and receipt of any regulatory approvals.

A  change  in  the  outcome  of  any  of  these  variables  with  respect  to  the  development  of  spinal  fusion,  joint  replacement  or  coated  metal
product candidates could mean a significant change in the costs and timing associated with the development of these product candidates.

In  addition,  the  repayment  of  the  loan  under  the  Loan  and  Security Agreement  and  the  associated  liquidity  covenant  limit  (as  described
below) our ability to use our cash and cash equivalents to fund our operations and may restrict our ability to continue development of our
product candidates. Additionally, the Loan and Security Agreement restricts our ability to incur additional pari passu indebtedness, which
may reduce our ability to seek additional financing. If adequate funds are not available on a timely basis, we may terminate or delay the
development of one or more of our product candidates, or delay activities necessary to commercialize our product candidates. Additional
funding may not be available to us on acceptable terms, or at all. Any additional equity financing, if available, may not  be  available  on
favorable terms and will most likely be dilutive to our current stockholders, and debt financing, if available, may involve more restrictive
covenants.  Our  ability  to  access  capital  when  needed  is  not  assured  and,  if  not  achieved  on  a  timely  basis,  will  materially  harm  our
business, financial condition and results of operations or could cause us to cease operations.

As  a  result  of  our  debt  obligations,  we  will  need  additional  funds  to  meet  our  operational  needs  and  capital  requirements  for  product
development, clinical trials and commercialization. The timing and amount of our future capital requirements will depend on many factors,
including:

● our ability to satisfy our obligation to pay principal and interest on the Loan and Security Agreement;

● our ability to comply with the minimum liquidity covenant related to the Loan and Security Agreement;

● the level of sales of our current products and the cost of revenue and sales and marketing;

● the extent of any clinical trials that we will be required to conduct in support of the regulatory clearance of our total hip and

knee replacement product candidates;

● the scope, progress, results and cost of our product development efforts;

● the costs, timing and outcomes of regulatory reviews of our product candidates;

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

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

related claims; and

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

If we do not adhere to the covenants set forth in the Exchange Notes, we will be in default of the Exchange Notes.

On January 3, 2018, we entered into an Assignment Agreement (the “Assignment Agreement”) with MEF I, LP and Anson Investments
Master Fund, LP (the “Assignees” and each an “Assignee”), Hercules Technology III, L.P. (“HT III”) and Hercules Capital, Inc. (“HC”
and, together with HT III, “Hercules”), pursuant to which Hercules assigned to the Assignees all amounts remaining due under the Loan
and Security Agreement, dated June 30, 2014, as amended, between the Company and Hercules (the “Loan and Security Agreement”) and
(2)  the  note  (the  “Hercules  Note”)  between  the  Company  and  Hercules  evidencing  the  amounts  due  under  the  Loan  and  Security
Agreement. The total amount assigned by Hercules to the Assignees equals in the aggregate $2.2 million, which is secured by the same
collateral underlying the Loan and Security Agreement.

On  January  3,  2018,  we  entered  into  an  exchange  agreement  (the  “Exchange Agreement”)  with  the Assignees,  pursuant  to  which  the
Company agreed to exchange (the “Exchange”) the Hercules Note held by the Assignees for senior secured convertible promissory notes
each in the principal amount of $1.1 million for an aggregate principal amount of $2.3 million (the “Exchange Notes”).

The Exchange Notes contain certain covenants and other obligations to which we are required to adhere to while the Exchange Notes are
outstanding. If we were to breach any of these covenants or obligations the Assignees could declare that an event of default has occurred
under  the  Exchange  Notes,  and  declare  that  the  outstanding  principal  amount  of  the  Exchange  Notes,  plus  accrued  but  unpaid  interest,
liquidated damages and other amounts owing in respect thereof through the date of acceleration, immediately due and payable, in cash or in
shares of common stock. Additionally, after the occurrence of any event of default, the interest rate on the Exchange Notes shall accrue at
an additional interest rate equal to the lesser of two percent (2%) per month (twenty-four percent (24%) per annum) or the maximum rate
permitted under applicable law. Any declaration of an event of default would significantly harm our business and prospects and could cause
the price of our common stock to decline.

If we do not adhere to the covenants set forth in the Note, we will be in default of the Note.

On  January  31,  2018,  we  entered  into  a  securities  purchase  agreement  (the  “Purchase Agreement”)  with  L2  Capital  LLC  (“L2”  or  the
“Holder”). Pursuant to the Purchase Agreement, the Company agreed to sell an original issue discount promissory note in the aggregate
principal  amount  of  up  to  $0.8  million  (the  “Note”)  for  an  aggregate  purchase  price  of  up  to  $0.8  million  (the  “Consideration”)  and
warrants to purchase up to an aggregate of 68,257 shares of common stock of the Company (the “Warrants”).

The Note contains certain covenants and other obligations to which we are required to adhere to while the Note is outstanding. If we were
to breach any of these covenants or obligations the Holder could declare that an event of default has occurred under the Note, and declare
that the outstanding principal amount of the Note, plus accrued but unpaid interest, liquidated damages and other amounts owing in respect
thereof  through  the  date  of  acceleration,  immediately  due  and  payable,  in  cash  or  in  shares  of  common  stock. Additionally,  after  the
occurrence of any event of default, the interest rate on the Note shall accrue at an additional interest rate equal to eighteen percent (18%)
per  annum  or  the  maximum  rate  permitted  under  applicable  law. Any  declaration  of  an  event  of  default  would  significantly  harm  our
business and prospects and could cause the price of our common stock to decline.

Raising  additional  capital  by  issuing  securities  or  through  debt  financings  or  licensing  arrangements  may  cause  dilution  to  existing
stockholders, restrict our operations or require us to relinquish proprietary rights.

To  the  extent  that  we  raise  additional  capital  through  the  sale  of  equity  or  convertible  debt  securities,  your  ownership  interest  may  be
diluted,  and  the  terms  may  include  liquidation  or  other  preferences  that  adversely  affect  your  rights  as  a  stockholder.  Debt  financing,  if
available,  may  involve  agreements  that  include  covenants  limiting  or  restricting  our  ability  to  take  specific  actions  such  as  incurring
additional debt, making capital expenditures or declaring dividends. Further, our current debt obligations to our current debt holders could
also  impair  our  ability  to  raise  future  capital  through  equity  or  debt  transactions.  If  we  raise  additional  funds  through  collaboration  and
licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or products or grant licenses on
terms  that  are  not  favorable  to  us.  Any  of  these  events  could  adversely  affect  our  ability  to  achieve  our  product  development  and
commercialization goals and have a material adverse effect on our business, financial condition and results of operations.

Our independent registered public accounting firm has included an explanatory paragraph relating to our ability to continue as a going
concern in its report on our audited financial statements. We may be unable to continue to operate without the threat of liquidation for
the foreseeable future

Our  report  from  our  independent  registered  public  accounting  firm  for  the  year  ended  December  31,  2017  includes  an  explanatory
paragraph stating that our recurring losses from operations raises substantial doubt about our ability to continue as a going concern. If we
are unable to obtain sufficient additional funding, our business, prospects, financial condition and results of operations will be materially
and adversely affected and we may be unable to continue as a going concern. If we are unable to continue as a going concern, we may have
to liquidate our assets and may receive less than the value at which those assets are carried on our consolidated financial statements, and it
is likely that investors will lose all or a part of their investment. Future reports from our independent registered public accounting firm may
also  contain  statements  expressing  doubt  about  our  ability  to  continue  as  a  going  concern.  If  we  seek  additional  financing  to  fund  our
business  activities  in  the  future  and  there  remains  doubt  about  our  ability  to  continue  as  a  going  concern,  investors  or  other  financing
sources may be unwilling to provide additional funding on commercially reasonable terms or at all.

We have identified material weaknesses in our internal control over financial reporting and such weaknesses have led to a conclusion
that  our  disclosure  controls  and  procedures  were  not  effective  as  of  December  31,  2017.  Our  ability  to  remediate  these  material
weaknesses,  our  discovery  of  additional  weaknesses,  and  our  inability  to  achieve  and  maintain  effective  disclosure  controls  and
procedures and internal control over financial reporting, have and could continue to adversely affect our results of operations, our stock
price and investor confidence in our company.

Section  404  of  the  Sarbanes-Oxley Act  of  2002  requires  that  companies  evaluate  and  report  on  their  systems  of  internal  control  over
financial  reporting. As  disclosed  in  more  detail  under  “Controls  and  Procedures”  in  Part  II,  Item  9A  of  this  Report,  management  has
concluded  that,  as  of  December  31,  2017,  our  internal  control  over  financial  reporting  was  not  effective  due  to  the  material  weaknesses
described below.

The design and operating effectiveness of our controls were inadequate to ensure that complex accounting matters are properly accounted
for and reviewed in a timely manner. As a result, we failed to accurately record a complex equity transaction which caused the restatements
of our first, second and third quarter 2017 filings and annual 2016 filing. In addition, we failed to properly evaluate and test certain long-
lived assets for impairment, which ultimately resulted in recognition of an impairment charge. These errors are a result of the following
control deficiencies:

Control Environment and Risk Assessment – The Company did not have an effective control environment with the structure necessary
for effective internal controls over financial reporting. Further, the Company did not have an effective risk assessment to identify and assess
risks  associated  with  changes  to  the  Company’s  structure  and  the  impact  on  internal  controls.  The  Company  did  not  have  appropriately
qualified  personnel  to  meet  the  Company’s  control  objectives.  The  Company  does  not  have  personnel  with  an  appropriate  level  of  US
GAAP knowledge and experience to properly review and evaluate the work performed by other Company personnel and experts related to
complex accounting matters.

Control Activities  –  The  Company  did  not  have  control  activities  that  were  designed  and  operating  effectively  including  management
review controls, controls related to monitoring and assessing the work of consultants, and controls to verify the completeness and adequacy
of  information.  Specifically,  the  Company  did  not  have  procedures  for  competent  personnel  to  review  work  performed  by  experts  in
relation to complex debt and equity transactions and impairment valuations.

Monitoring  Activities  –  The  Company  did  not  maintain  effective  monitoring  controls  related  to  the  financial  reporting  process.  The
Company did not effectively monitor the changes in internal control related to changes in the roles and responsibilities associated with the
changes in personnel and organizational structure. The failure to properly monitor impacted the timing, accuracy, and completion of the
work related to significant accounting matters.

Our Chief Executive Officer and Principal Financial Officer continue with a review of our controls relating to complex accounting matters.
Although our analysis is not complete, we have added additional resources with expertise in accounting for complex accounting matters
including timely review and evaluation of assets for potential impairment. We are also considering redesigning controls to add additional
layers  of  review  and  approval  whenever  entering  into  or  subsequently  converting,  exercising,  amending,  repricing,  exiting  or  otherwise
experiencing changes in or to complex financial instruments.

If we fail to remediate these material weaknesses and maintain an effective system of disclosure controls or internal control over financial
reporting, our business and results of operations could be harmed, investors could lose confidence in our reported financial information and
our ability to obtain additional financing, or additional financing on favorable terms, could be adversely affected. Any of these could result
in delisting actions by the NASDAQ Stock Market, investigation and sanctions by regulatory authorities, and adversely affect our business
and the trading price of our common stock. In addition, failure to maintain effective internal control over financial reporting could result in
investigations or sanctions by regulatory authorities.

An impairment charge could have a material adverse effect on our financial condition and results of operations

We are required to test acquired goodwill for impairment on an annual basis. Goodwill represents the excess of the amount paid over the
fair value of the net assets at the date of the acquisition. We have chosen to complete our annual impairment reviews of goodwill at the end
of each calendar year. We also are required to test goodwill for impairment between annual tests if events occur or circumstances change
that would more likely than not reduce our enterprise fair value below its book value. In addition, we are required to test our definite-lived
intangible assets for impairment if events occur or circumstances change that would indicate the remaining net book value of the definite-
lived intangible assets might not be recoverable. These events or circumstances could include a significant change in the business climate,
including  a  significant  sustained  decline  in  our  market  value,  legal  factors,  operating  performance  indicators,  competition,  sale  or
disposition of a significant portion of our business and other factors.

If the fair market value of our reporting unit is less than its book value, we could be required to record an impairment charge. The valuation
of  a  reporting  unit  requires  judgment  in  estimating  future  cash  flows,  discount  rates  and  other  factors.  In  making  these  judgments,  we
evaluate  the  financial  health  of  our  business,  including  such  factors  as  industry  performance,  changes  in  technology  and  operating  cash
flows. Changes in our forecasts or decreases in the value of our common stock could cause book values of our reporting unit to exceed its
fair value, which may result in goodwill impairment charges. The amount of any impairment could be significant and could have a material
adverse effect on our reported financial results for the period in which the charge is taken.

Risks Related to Regulatory Approval of Our Products and Other Government Regulations

Our long-term success depends substantially on our ability to obtain regulatory clearance or approval and thereafter commercialize our
product candidates; we cannot be certain that we will be able to do so in a timely manner or at all.

The  process  of  obtaining  regulatory  clearances  or  approvals  to  market  a  medical  device  from  the  FDA  or  similar  regulatory  authorities
outside  of  the  United  States  can  be  costly  and  time  consuming,  and  there  can  be  no  assurance  that  such  clearances  or  approvals  will  be
granted on a timely basis, or at all. The FDA’s 510(k) clearance process generally takes one to six months from the date of submission,
depending  on  whether  a  special  or  traditional  510(k)  premarket  notification  has  been  submitted,  but  can  take  significantly  longer. An
application for premarket approval, or PMA, must be submitted to the FDA if the device cannot be cleared through the 510(k) clearance
process or is not exempt from premarket review by the FDA. The PMA process almost always requires one or more clinical trials and can
take two to three years from the date of filing, or even longer. In some cases, including in the case of our interbody spinal fusion devices
which incorporate our CSC technology and our solid silicon nitride femoral head component, the FDA requires clinical data as part of the
510(k) clearance process.

It is possible that the FDA could raise questions about our spinal fusion products, our spinal fusion product candidates and our total hip and
knee joint replacement product candidates and could require us to perform additional studies on our products and product candidates. Even
if the FDA permits us to use the 510(k) clearance process, we cannot assure you that the FDA will not require either supporting data from
laboratory tests or studies that we have not conducted, or substantial supporting clinical data. If we are unable to use the 510(k) clearance
process  for  any  of  our  product  candidates,  are  required  to  provide  clinical  data  or  laboratory  data  that  we  do  not  possess  to  support  our
510(k) premarket notifications for any of these product candidates, or otherwise experience delays in obtaining or fail to obtain regulatory
clearances, the commercialization of our product candidates in the United States will be delayed or prevented, which will adversely affect
our ability to generate additional revenues. It also may result in the loss of potential competitive advantages that we might otherwise attain
by  bringing  our  products  to  market  earlier  than  our  competitors. Additionally,  although  the  FDA  allows  modifications  to  be  made  to
devices that have received 510(k) clearance with supporting documentation, the FDA may disagree with our decision to modify our cleared
devices  without  submission  of  a  new  510(k)  premarket  notification,  subjecting  us  to  potential  product  recall,  field  alerts  and  corrective
actions. Any of these contingencies could adversely affect our business.

Similar to our compliance with U.S. regulatory requirements, we must obtain and comply with international requirements, including those
of the CFDA, in order to market and sell our products outside of the United States and we may only promote and market our products, if
approved, as permitted by applicable regulatory authorities. There is no guarantee that we will receive the necessary regulatory approvals
for our product candidates either inside the United States or internationally, including approvals from the CFDA. If our product candidates
do not receive necessary regulatory approvals, our business could be materially and adversely affected.

40

 
 
 
 
 
 
 
 
 
 
 
 
The  safety  of  our  products  is  not  yet  supported  by  long-term  clinical  data,  and  they  may  prove  to  be  less  safe  and  effective  than  our
laboratory data indicate.

We obtained FDA clearance for each of our products that we currently market, and we have sought and intend to seek FDA clearance or
approval through the FDA’s 510(k) or PMA process and, where applicable, CE marking for our product candidates. The 510(k) clearance
process is based on the FDA’s agreement that a new product candidate is substantially equivalent to an already marketed product for which
a PMA was not required. While most 510(k) premarket notifications do not require clinical data for clearance, the FDA may request that
such  data  be  provided.  Long-term  clinical  data  or  marketing  experience  obtained  after  clearance  may  indicate  that  our  products  cause
unexpected  complications  or  other  unforeseen  negative  effects.  If  this  happens,  we  could  be  subject  to  the  withdrawal  of  our  marketing
clearance and other enforcement sanctions by the FDA or other regulatory authority, product recalls, significant legal liability, significant
negative publicity, damage to our reputation and a dramatic reduction in our ability to sell our products, any one of which would have a
material adverse effect on our business, financial condition and results of operations.

We  expect  to  be  required  to  conduct  clinical  trials  to  support  regulatory  approval  of  some  of  our  product  candidates.  We  have  little
experience  conducting  clinical  trials,  they  may  proceed  more  slowly  than  anticipated,  and  we  cannot  be  certain  that  our  product
candidates will be shown to be safe and effective for human use.

In order to commercialize our product candidates in the United States, we must submit a PMA for some of these product candidates, which
will require us to conduct clinical trials. We also plan to provide the FDA with clinical trial data to support some of our 510(k) premarket
notifications.  We  will  receive  approval  or  clearance  from  the  FDA  to  commercialize  products  requiring  a  clinical  trial  only  if  we  can
demonstrate to the satisfaction of the FDA, through well-designed and properly conducted clinical trials, that our product candidates are
safe and effective and otherwise meet the appropriate standards required for approval or clearance for specified indications.

Clinical trials are complex, expensive, time consuming, uncertain and subject to substantial and unanticipated delays. Before we may begin
clinical trials, we must submit and obtain approval for an investigational device exemption, or IDE, that describes, among other things, the
manufacture of, and controls for, the device and a complete investigational plan. Clinical trials generally involve a substantial number of
patients in a multi-year study. Because we do not have the experience or the infrastructure necessary to conduct clinical trials, we will have
to hire one or more contract research organizations, or CROs, to conduct trials on our behalf. CRO contract negotiations may be costly and
time consuming and we will rely heavily on the CRO to ensure that our trials are conducted in accordance with regulatory and industry
standards. We may encounter problems with our clinical trials and any of those problems could cause us or the FDA to suspend those trials,
or delay the analysis of the data derived from them.

A number of events or factors, including any of the following, could delay the completion of our clinical trials in the future and negatively
impact our ability to obtain FDA approval for, and to introduce our product candidates:

● failure to obtain financing necessary to bear the cost of designing and conducting clinical trials;

● failure to obtain approval from the FDA or foreign regulatory authorities to commence investigational studies;

● conditions imposed on us by the FDA or foreign regulatory authorities regarding the scope or design of our clinical trials;

● failure to find a qualified CRO to conduct our clinical trials or to negotiate a CRO services agreement on favorable terms;

● delays in  obtaining  or  in  our  maintaining  required  approvals  from  institutional  review  boards  or  other  reviewing  entities  at

clinical sites selected for participation in our clinical trials;

● insufficient supply of our product candidates or other materials necessary to conduct our clinical trials;

● difficulties in enrolling patients in our clinical trials;

● negative or inconclusive results from clinical trials, or results that are inconsistent with earlier results, that necessitate additional

clinical studies;

● failure on the part of the CRO to conduct the clinical trial in accordance with regulatory requirements;

● our failure  to  maintain  a  successful  relationship  with  the  CRO  or  termination  of  our  contractual  relationship  with  the  CRO

before completion of the clinical trials;

● serious or unexpected side effects experienced by patients in whom our product candidates are implanted; or

● failure by any of our third-party contractors or investigators to comply with regulatory requirements or meet other contractual

obligations in a timely manner.

Our  clinical  trials  may  need  to  be  redesigned  or  may  not  be  completed  on  schedule,  if  at  all.  Delays  in  our  clinical  trials  may  result  in
increased  development  costs  for  our  product  candidates,  which  could  cause  our  stock  price  to  decline  and  limit  our  ability  to  obtain
additional  financing.  In  addition,  if  one  or  more  of  our  clinical  trials  are  delayed,  competitors  may  be  able  to  bring  products  to  market
before we do, and the commercial viability of our product candidates could be significantly reduced.

Our current and future relationships with third-party payers and current and potential customers in the United States and elsewhere
may  be  subject,  directly  or  indirectly,  to  applicable  anti-kickback,  fraud  and  abuse,  false  claims,  transparency,  health  information
privacy  and  security  and  other  healthcare  laws  and  regulations,  which  could  expose  us  to  criminal  sanctions,  civil  penalties,
contractual damages, reputational harm administrative burdens and diminished profits and future earnings.

Our  current  and  future  arrangements  with  third-party  payers  and  current  and  potential  customers,  including  providers  and  physicians,  as
well  as  physician  owned  distributorships  or  PODs,  may  expose  us  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and
regulations,  including,  without  limitation,  the  federal Anti-Kickback  Statute  and  the  federal  False  Claims Act,  which  may  constrain  the
business  or  financial  arrangements  and  relationships  through  which  we  sell,  market  and  distribute  our  products.  In  addition,  we  may  be
subject  to  transparency  laws  and  patient  privacy  regulations  by  U.S.  federal  and  state  governments  and  by  governments  in  foreign
jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws and regulations that may affect our
ability to operate include:

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

● federal civil  and  criminal  false  claims  laws  and  civil  monetary  penalty  laws,  including  the  federal  False  Claims Act,  which
impose criminal  and  civil  penalties,  including  civil  whistleblower  or  qui  tam  actions,  against  individuals  or  entities  for
knowingly presenting, or causing to be presented, to the federal government, including the Medicare and Medicaid programs,
claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay
money to the federal government;

● the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability
for executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

42

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and
their  respective implementing  regulations,  which  impose  obligations  on  covered  healthcare  providers,  health  plans,  and
healthcare clearinghouses, as well as their business associates that create, receive, maintain or transmit individually identifiable
health information for or on behalf of a covered entity, with respect to safeguarding the privacy, security and transmission of
individually identifiable health information;

● the Physician Payments Sunshine Act, which requires (i) 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
report  annually  to  CMS  information  related  to  certain  “payments  or  other  transfers  of  value”  made  to  physicians, which  is
defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors,  and  teaching  hospitals,  with  data collection
beginning on August 1, 2013, (ii) applicable manufacturers and applicable group purchasing organizations to report  annually to
CMS  ownership  and  investment  interests  held  in  such  entities  by  physicians  and  their  immediate  family  members, with  data
collection beginning on August 1, 2013, (iii) manufacturers to submit reports to CMS by March 31, 2014 and the 90th  day of
each subsequent calendar year, and (iv) disclosure of such information by CMS on a publicly available website beginning in
September 2014; and

● analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or
marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payers,
including private  insurers;  state  and  foreign  laws  that  require  medical  device  companies  to  comply  with  the  medical  device
industry’s voluntary  compliance  guidelines  and  the  relevant  compliance  guidance  promulgated  by  the  federal  government  or
otherwise  restrict payments  that  may  be  made  to  healthcare  providers;  state  and  foreign  laws  that  require  medical  device
manufacturers  to  report information  related  to  payments  and  other  transfers  of  value  to  physicians  and  other  healthcare
providers  or  marketing  expenditures; and  state  and  foreign  laws  governing  the  privacy  and  security  of  health  information  in
certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus
complicating compliance efforts. Efforts to ensure that our business arrangements with third parties will comply with applicable
healthcare laws and regulations may involve substantial costs. It is possible that governmental authorities will conclude that our
business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse
or  other  healthcare  laws and  regulations.  If  our  operations  are  found  to  be  in  violation  of  any  of  these  laws  or  any  other
governmental  regulations that  may  apply  to  us,  we  may  be  subject  to  significant  civil,  criminal  and  administrative  penalties,
including, without limitation, damages, fines, imprisonment, exclusion from participation in government healthcare programs,
such  as  Medicare  and  Medicaid, and  the  curtailment  or  restructuring  of  our  operations,  which  could  have  a  material  adverse
effect on our business. If any of the physicians or other healthcare providers or entities with whom we expect to do business,
including our collaborators, are found not to be in compliance with applicable laws, they may be subject to criminal, civil or
administrative  sanctions, including  exclusions  from  participation  in  government  healthcare  programs,  which  could  also
materially affect our business.

U.S. federal income tax reform could adversely affect us.

On  December  22,  2017,  President  Donald  Trump  signed  into  law  sweeping  tax  reform,  which  overhauls  individual,  business  and
international taxes including, but not limited to:

● Cutting the corporate federal statutory tax rate to 21%;

● Limiting net interest expense deductions to 30% of adjusted taxable income; and

● Limiting the net operating loss deduction to 80% of taxable income.

43

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The reduction in tax rate will result in a reduction in the deferred tax assets. We have previously used the 35% federal statutory tax rate to
calculate the value of those assets. Also, if we fail to generate significant taxable income, we may not be able to fully deduct the interest
expense  on  our  debt,  which  could  result  in  us  having  to  pay  increased  federal  income  taxes.  We  have  also  generated  substantial  taxable
losses in the past and may continue to do so in the future. Although the treatment of tax losses generated before December 31, 2017 has not
changed,  tax  losses  generated  in  fiscal  2018  and  beyond  will  only  be  able  to  offset  80%  of  taxable  income,  although  the  losses  may  be
carried  forward  indefinitely.  This  could  cause  us  to  have  to  pay  federal  income  taxes  despite  generating  a  loss  for  federal  income  tax
purposes  in  the  future.  We  continue  to  work  with  our  tax  advisors  to  determine  the  full  impact  that  the  new  tax  bill  will  have  on  our
Company.

Recently  enacted  and  future  legislation  may  increase  the  difficulty  and  cost  for  us  to  obtain  and  monitor  regulatory  approval  or
clearance of our product candidates and affect the prices we may obtain for our products.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes
regarding the healthcare system that could prevent or delay clearance and/or approval of our product candidates, restrict or regulate post-
clearance and post-approval activities and affect our ability to profitably sell our products and any product candidates for which we obtain
marketing approval or clearance.

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. Delays in receipt of or failure to receive regulatory clearances or approvals for our new products would have
a  material  adverse  effect  on  our  business,  results  of  operations  and  financial  condition.  In  addition,  the  FDA  is  currently  evaluating  the
510(k) process and may make substantial changes to industry requirements, including which devices are eligible for 510(k) clearance, the
ability to rescind previously granted 510(k) clearances and additional requirements that may significantly impact the process.

Among  policy  makers  and  payers  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  and  expanding  access.  In  the  United  States,  the  medical
device  industry  has  been  a  particular  focus  of  these  efforts  and  has  been  significantly  affected  by  major  legislative  initiatives.  In  March
2010,  President  Obama  signed  into  law  the  Patient  Protection  and Affordable  Care Act,  as  amended  by  the  Health  Care  and  Education
Affordability  Reconciliation Act,  or  collectively  the ACA,  a  sweeping  law  intended,  among  other  things,  to  broaden  access  to  health
insurance,  reduce  or  constrain  the  growth  of  healthcare  spending,  enhance  remedies  against  fraud  and  abuse,  add  new  transparency
requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional
health policy reforms.

Among the provisions of the ACA of importance to our products and product candidates are:

● imposes an  annual  excise  tax  of  2.3%  on  any  entity  that  manufactures  or  imports  medical  devices  offered  for  sale  in  the  United
States, which began on January 1, 2013, but was suspended during 2016 and 2017 and has been suspended for 2018 and 2019;

● 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; and

● 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 healthcare services through bundled payment models.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. For example, on January 2, 2013,
former  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, 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.  Moreover,  certain  legislative
changes  to  and  regulatory  changes  under  the  PPACA  have  occurred  in  the  115th  United  States  Congress  and  under  the  Trump
Administration.  For  example,  on  December  22,  2017,  President  Trump  signed  a  budget  reconciliation  act  into  law,  which  among  other
things, repealed the penalty for individuals who do not maintain minimum essential coverage, which was a central component of PPACA’s
approach  to  expanding  coverage.  On  January  9,  2018,  President  Trump  signed  the  Bipartisan  Budget Act  of  2018,  which,  among  other
things, repealed the PPACA provision establishing an independent payment advisory board that would have submitted recommendations to
reduce Medicare spending if projected Medicare spending exceeded a specified growth rate.

Additional  legislative  changes  to  and  regulatory  changes  under  the  PPACA  remain  possible.  We  expect  that  other  state  and  federal
healthcare  reform  measures  will  be  adopted  in  the  future,  any  of  which  could  reduce  the  number  of  patients  with  coverage  or  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.

In the European Union and some other international markets, the government provides health care at a low cost to consumers and regulates
prices of healthcare products, patient eligibility or reimbursement levels to control costs for the government-sponsored health care system.
Many  countries  are  reducing  their  public  expenditures  and  we  expect  to  see  strong  efforts  to  reduce  healthcare  costs  in  international
markets,  including  patient  access  restrictions,  suspensions  on  price  increases,  prospective  and  possibly  retroactive  price  reductions  and
other recoupments and increased mandatory discounts or rebates and recoveries of past price increases. These cost control measures could
reduce our revenues. In addition, certain countries set prices by reference to the prices in other countries where our products are marketed.
Thus, our inability to secure adequate prices in a particular country may not only limit the marketing of our products within that country,
but may also adversely affect our ability to obtain acceptable prices in other markets. This may create the opportunity for third-party cross
border trade or influence our decision to sell or not to sell a product, thus adversely affecting our geographic expansion plans and revenues.

Risks Related to Our Intellectual Property and Litigation

If the combination of patents, trade secrets and contractual provisions that we rely on to protect our intellectual property is inadequate,
our  ability  to  commercialize  our  orthopedic  products  successfully  will  be  harmed,  and  we  may  not  be  able  to  operate  our  business
profitably.

Our success depends significantly on our ability to protect our proprietary rights to the technologies incorporated in our products. We rely
on a combination of patent protection, trade secret laws and nondisclosure, confidentiality and other contractual restrictions to protect our
proprietary technology. However, these may not adequately protect our rights or permit us to gain or keep any competitive advantage.

The  issuance  of  a  patent  is  not  conclusive  as  to  its  scope,  validity  or  enforceability.  The  scope,  validity  or  enforceability  of  our  issued
patents  can  be  challenged  in  litigation  or  proceedings  before  the  U.S.  Patent  and  Trademark  Office,  or  the  USPTO,  or  foreign  patent
offices. In addition, our pending patent applications include claims to numerous important aspects of our products under development that
are not currently protected by any of our issued patents. We cannot assure you that any of our pending patent applications will result in the
issuance of patents to us. The USPTO or foreign patent offices may deny or require significant narrowing of claims in our pending patent
applications. Patents issued as a result of the pending patent applications, if any, may not provide us with significant commercial protection
or be issued in a form that is advantageous to us. Proceedings before the USPTO or foreign patent offices could result in adverse decisions
as to the priority of our inventions and the narrowing or invalidation of claims in issued patents. The laws of some foreign countries may
not protect our intellectual property rights to the same extent as the laws of the United States, if at all.

Our competitors may successfully challenge and invalidate or render unenforceable our issued patents, including any patents that may issue
in the future, which could prevent or limit our ability to market our products and could limit our ability to stop competitors from marketing
products that are substantially equivalent to ours. In addition, competitors may be able to design around our patents or develop products that
provide outcomes that are comparable to our products but that are not covered by our patents.

We have also entered into confidentiality and assignment of intellectual property agreements with all of our employees, consultants and
advisors as one of the ways we seek to protect our intellectual property and other proprietary technology. However, these agreements may
not  be  enforceable  or  may  not  provide  meaningful  protection  for  our  trade  secrets  or  other  proprietary  information  in  the  event  of
unauthorized use or disclosure or other breaches of the agreements.

45

 
 
 
 
 
 
 
 
 
 
 
 
In the event a competitor infringes upon any of our patents or other intellectual property rights, enforcing our rights may be difficult, time
consuming and expensive, and would divert management’s attention from managing our business. There can be no assurance that we will
be successful on the merits in any enforcement effort. In addition, we may not have sufficient resources to litigate, enforce or defend our
intellectual property rights.

We have no patent protection covering the composition of matter for our solid silicon nitride or the process we use for manufacturing
our solid silicon nitride, and competitors may create silicon nitride formulations substantially similar to ours.

Although we have a number of U.S. and foreign patents and pending applications relating to our solid silicon nitride products or product
candidates, we have no patent protection either for the composition of matter for our silicon nitride or for the processes of manufacturing
solid silicon nitride. As a result, competitors may create silicon nitride formulations substantially similar to ours, and use their formulations
in products that may compete with our silicon nitride products, provided they do not violate our issued product patents. Although we have,
and will continue to develop, significant know-how related to these processes, there can be no assurance that we will be able to maintain
this  know-how  as  trade  secrets,  and  competitors  may  develop  or  acquire  equally  valuable  or  more  valuable  know-how  related  to  the
manufacture of silicon nitride.

We could become subject to intellectual property litigation that could be costly, result in the diversion of management’s time and efforts,
require  us  to  pay  damages,  prevent  us  from  marketing  our  commercially  available  products  or  product  candidates  and/or  reduce  the
margins we may realize from our products that we may commercialize.

The  medical  devices  industry  is  characterized  by  extensive  litigation  and  administrative  proceedings  over  patent  and  other  intellectual
property rights. Whether a product infringes a patent involves complex legal and factual issues, and the determination is often uncertain.
There may be existing patents of which we are unaware that our products under development may inadvertently infringe. The likelihood
that patent infringement claims may be brought against us increases as the number of participants in the orthopedic market increases and as
we achieve more visibility in the market place and introduce products to market.

Any infringement claim against us, even if without merit, may cause us to incur substantial costs, and would place a significant strain on
our financial resources, divert the attention of management from our core business, and harm our reputation. In some cases, litigation may
be  threatened  or  brought  by  a  patent  holding  company  or  other  adverse  patent  owner  who  has  no  relevant  product  revenues  and  against
whom our patents may provide little or no deterrence. If we were found to infringe any patents, we could be required to pay substantial
damages, including triple damages if an infringement is found to be willful, and royalties and could be prevented from selling our products
unless we obtain a license or are able to redesign our products to avoid infringement. We may not be able to obtain a license enabling us to
sell our products on reasonable terms, or at all, and there can be no assurance that we would be able to redesign our products in a way that
would  not  infringe  those  patents.  If  we  fail  to  obtain  any  required  licenses  or  make  any  necessary  changes  to  our  technologies  or  the
products that incorporate them, we may be unable to commercialize one or more of our products or may have to withdraw products from
the market, all of which would have a material adverse effect on our business, financial condition and results of operations.

In  addition,  in  order  to  further  our  product  development  efforts,  we  have  entered  into  agreements  with  orthopedic  surgeons  to  help  us
design and develop new products, and we expect to enter into similar agreements in the future. In certain instances, we have agreed to pay
such  surgeons  royalties  on  sales  of  products  which  incorporate  their  product  development  contributions.  There  can  be  no  assurance  that
surgeons with whom we have entered into such arrangements will not claim to be entitled to a royalty even if we do not believe that such
products  were  developed  by  cooperative  involvement  between  us  and  such  surgeons.  In  addition,  some  of  our  surgeon  advisors  are
employed by academic or medical institutions or have agreements with other orthopedic companies pursuant to which they have agreed to
assign or are under an obligation to assign to those other companies or institutions their rights in inventions which they conceive or develop,
or help conceive or develop.

46

 
 
 
 
 
 
 
 
 
 
 
There can be no assurance that one or more of these orthopedic companies or institutions will not claim ownership rights to an invention we
develop  in  collaboration  with  our  surgeon  advisors  or  consultants  on  the  basis  that  an  agreement  with  such  orthopedic  company  or
institution gives it ownership rights in the invention or that our surgeon advisors on consultants otherwise have an obligation to assign such
inventions  to  such  company  or  institution. Any  such  claim  against  us,  even  without  merit,  may  cause  us  to  incur  substantial  costs,  and
would  place  a  significant  strain  on  our  financial  resources,  divert  the  attention  of  management  from  our  core  business  and  harm  our
reputation.

We may be subject to damages resulting from claims that we, our employees, or our independent sales agencies have wrongfully used or
disclosed  alleged  trade  secrets  of  our  competitors  or  are  in  breach  of  non-competition  agreements  with  our  competitors  or  non-
solicitation agreements.

Many  of  our  employees  were  previously  employed  at  other  orthopedic  companies,  including  our  competitors  and  potential  competitors.
Many of our distributors and potential distributors sell, or in the past have sold, products of our competitors. We may be subject to claims
that either we, or these employees or distributors, have inadvertently or otherwise used or disclosed the trade secrets or other proprietary
information of our competitors. In addition, we have been and may in the future be subject to claims that we caused an employee or sales
agent  to  break  the  terms  of  his  or  her  non-competition  agreement  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  be  a
distraction to management. If we fail in defending such claims, in addition to paying money damages, we may lose valuable intellectual
property rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to commercialize products,
which could have an adverse effect on our business, financial condition and results of operations.

If our silicon nitride products or our product candidates conflict with the rights of others, we may not be able to manufacture or market
our products or product candidates, which could have a material and adverse effect on us.

Our commercial success will depend in part on not infringing the patents or violating the other proprietary rights of third parties. Issued
patents held by others may limit our ability to develop commercial products. All issued patents are entitled to a presumption of validity
under the laws of the United States. If we need suitable licenses to such patents to permit us to develop or market our product candidates,
we  may  be  required  to  pay  significant  fees  or  royalties  and  we  cannot  be  certain  that  we  would  even  be  able  to  obtain  such  licenses.
Competitors or third parties may obtain patents that may cover subject matter we use in developing the technology required to bring our
products to market, that we use in producing our products, or that we use in treating patients with our products. We know that others have
filed  patent  applications  in  various  jurisdictions  that  relate  to  several  areas  in  which  we  are  developing  products.  Some  of  these  patent
applications have already resulted in patents and some are still pending. If we were found to infringe any of these issued patents or any of
the pending patent applications, when and if issued, we may be required to alter our processes or product candidates, pay licensing fees or
cease  activities.  If  use  of  technology  incorporated  into  or  used  to  produce  our  product  candidates  is  challenged,  or  if  our  processes  or
product candidates conflict with patent rights of others, third parties could bring legal actions against us, in Europe, the United States and
elsewhere, claiming damages and seeking to enjoin manufacturing and marketing of the affected products. Additionally, it is not possible to
predict with certainty what patent claims may issue from pending applications. In the United States, for example, patent prosecution can
proceed in secret prior to issuance of a patent, provided such application is not filed in foreign jurisdiction. For U.S. patent applications that
are also filed in foreign jurisdictions, such patent applications will not publish until 18 months from the filing date of the application. As a
result, third parties may be able to obtain patents with claims relating to our product candidates which they could attempt to assert against
us. Further, as we develop our products, third parties may assert that we infringe the patents currently held or licensed by them, and we
cannot predict the outcome of any such action.

There has been extensive litigation in the medical devices industry over patents and other proprietary rights. If we become involved in any
litigation,  it  could  consume  a  substantial  portion  of  our  resources,  regardless  of  the  outcome  of  the  litigation.  If  these  legal  actions  are
successful,  in  addition  to  any  potential  liability  for  damages,  we  could  be  required  to  obtain  a  license,  grant  cross-licenses  and  pay
substantial royalties in order to continue to manufacture or market the affected products.

We  cannot  assure  you  that  we  would  prevail  in  any  legal  action  or  that  any  license  required  under  a  third  party  patent  would  be  made
available on acceptable terms, or at all. Ultimately, we could be prevented from commercializing a product, or forced to cease some aspect
of our business operations, as a result of claims of patent infringement or violation of other intellectual property rights, which could have a
material and adverse effect on our business, financial condition and results of operations.

47

 
 
 
 
 
 
 
 
 
 
 
Risks Related to Potential Litigation from Operating Our Business

We  may  become  subject  to  potential  product  liability  claims,  and  we  may  be  required  to  pay  damages  that  exceed  our  insurance
coverage.

Our business exposes us to potential product liability claims that are inherent in the design, testing, manufacture, sale and distribution of
our currently marketed products and each of our product candidates that we are seeking to introduce to the market. The use of orthopedic
medical  devices  can  involve  significant  risks  of  serious  complications,  including  bleeding,  nerve  injury,  paralysis,  infection,  and  even
death. Any product liability claim brought against us, with or without merit, could result in the increase of our product liability insurance
rates  or  in  our  inability  to  secure  coverage  in  the  future  on  commercially  reasonable  terms,  if  at  all.  In  addition,  if  our  product  liability
insurance proves to be inadequate to pay a damage award, we may have to pay the excess of this award out of our cash reserves, which
could significantly harm our financial condition. If longer-term patient results and experience indicate that our products or any component
of  a  product  causes  tissue  damage,  motor  impairment  or  other  adverse  effects,  we  could  be  subject  to  significant  liability. A  product
liability claim, even one without merit, could harm our reputation in the industry, lead to significant legal fees, and result in the diversion of
management’s attention from managing our business.

Any claims relating to our improper handling, storage or disposal of biological or hazardous materials could be time consuming and
costly.

Although  we  do  not  believe  that  the  manufacture  of  our  silicon  nitride  or  non-silicon  nitride  products  will  involve  the  use  of  hazardous
materials, it is possible that regulatory authorities may disagree or that changes to our manufacturing processes may result in such use. Our
business and facilities and those of our suppliers and future suppliers may therefore be subject to foreign, federal, state and local laws and
regulations  governing  the  use,  manufacture,  storage,  handling  and  disposal  of  hazardous  materials  and  waste  products.  We  may  incur
significant expenses in the future relating to any failure to comply with environmental laws. Any such future expenses or liability could
have a significant negative impact on our business, financial condition and results of operations.

Risks Related to Our Common Stock

The price of our common stock is volatile and is likely to continue to fluctuate due to reasons beyond our control.

The volatility of orthopedic company stocks, including shares of our common stock, often do not correlate to the operating performance of
the  companies  represented  by  such  stocks  or  our  operating  performance.  Some  of  the  factors  that  may  cause  the  market  price  of  our
common stock to fluctuate include:

● our ability to sell our current products and the cost of revenue;

● our ability  to  develop,  obtain  regulatory  clearances  or  approvals  for,  and  market  new  and  enhanced  product  candidates  on  a

timely basis;

● our ability to enter into OEM and private label partnership agreements and the terms of those agreements;

● changes in governmental regulations or in the status of our regulatory approvals, clearances or future applications;

● our announcements or our competitors’ announcements regarding new products, product enhancements, significant contracts,
number and productivity of distributors, number of hospitals and surgeons using products, acquisitions or strategic investments;

● announcements of technological or medical innovations for the treatment of orthopedic pathology;

48

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● delays or other problems with the manufacturing of our products, product candidates and related instrumentation;

● volume and timing of orders for our products and our product candidates, if and when commercialized;

● changes in the availability of third-party reimbursement in the United States and other countries;

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

● changes in earnings estimates or recommendations by securities analysts, if any, who cover our common stock;

● failure to meet estimates or recommendations by securities analysts, if any, who cover our stock;

● changes in the fair value of our derivative liabilities resulting from changes in the market price of our common stock, which

may result in significant fluctuations in our quarterly and annual operating results;

● changes in healthcare policy in the United States and internationally;

● product liability claims or other litigation involving us;

● sales of a substantial aggregate number of shares of our common stock;

● sales of large blocks of our common stock, including sales by our executive officers, directors and significant stockholders;

● disputes or other developments with respect to intellectual property rights;

● changes in accounting principles;

● changes to tax policy; and

● general market  conditions  and  other  factors,  including  factors  unrelated  to  our  operating  performance  or  the  operating

performance of our competitors.

These and other external factors may cause the market price and demand for our common stock to fluctuate substantially, which may limit
or  prevent  our  stockholders  from  readily  selling  their  shares  of  common  stock  and  may  otherwise  negatively  affect  the  liquidity  of  our
common stock. In addition, in the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted
securities class action litigation against the company that issued the stock. If our stockholders brought a lawsuit against us, we could incur
substantial costs defending the lawsuit regardless of the merits of the case or the eventual outcome. Such a lawsuit also would divert the
time and attention of our management from running our company.

Securities  analysts  may  not  continue  to  provide  coverage  of  our  common  stock  or  may  issue  negative  reports,  which  may  have  a
negative impact on the market price of our common stock.

Since completing our initial public offering of shares of our common stock in February 2014, a limited number of securities analysts have
begun  providing  research  coverage  of  our  common  stock.  If  securities  analysts  do  not  continue  to  cover  our  common  stock,  the  lack  of
research coverage may cause the market price of our common stock to decline. The trading market for our common stock may be affected
in part by the research and reports that industry or financial analysts publish about our business. If one or more of the analysts who elect to
cover us downgrade our stock, our stock price would likely decline rapidly. If one or more of these analysts cease coverage of us, we could
lose visibility in the market, which in turn could cause our stock price to decline. In addition, under the Sarbanes-Oxley Act of 2002, or the
Sarbanes-Oxley Act, and a global settlement among the Securities and Exchange Commission, or the SEC, other regulatory agencies and a
number  of  investment  banks,  which  was  reached  in  2003,  many  investment  banking  firms  are  required  to  contract  with  independent
financial analysts for their stock research. It may be difficult for a company such as ours, with a smaller market capitalization, to attract
independent financial analysts that will cover our common stock. This could have a negative effect on the market price of our stock.

Anti-takeover provisions in our organizational documents and Delaware law may discourage or prevent a change in control, even if an
acquisition  would  be  beneficial  to  our  stockholders,  which  could  affect  our  stock  price  adversely  and  prevent  attempts  by  our
stockholders to replace or remove our current management.

Our  restated  certificate  of  incorporation  and  restated  bylaws  contain  provisions  that  could  discourage,  delay  or  prevent  a  merger,
acquisition or other change in control of our company or changes in our board of directors that our stockholders might consider favorable,
including  transactions  in  which  you  might  receive  a  premium  for  your  shares.  These  provisions  also  could  limit  the  price  that  investors
might  be  willing  to  pay  in  the  future  for  shares  of  our  common  stock,  thereby  depressing  the  market  price  of  our  common  stock.
Stockholders  who  wish  to  participate  in  these  transactions  may  not  have  the  opportunity  to  do  so.  Furthermore,  these  provisions  could
prevent or frustrate attempts by our stockholders to replace or remove management. These provisions:

● allow the authorized number of directors to be changed only by resolution of our board of directors;

● provide for a classified board of directors, such that not all members of our board will be elected at one time;

● prohibit our  stockholders  from  filling  board  vacancies,  limit  who  may  call  stockholder  meetings,  and  prohibit  the  taking  of

stockholder action by written consent;

● prohibit our stockholders from making certain changes to our restated certificate of incorporation or restated bylaws except with

the approval of holders of 75% of the outstanding shares of our capital stock entitled to vote;

● require advance  written  notice  of  stockholder  proposals  that  can  be  acted  upon  at  stockholders  meetings  and  of  director

nominations to our board of directors; and

● authorize our board of directors to create and issue, without prior stockholder approval, preferred stock that may have rights
senior to  those  of  our  common  stock  and  that,  if  issued,  could  operate  as  a  “poison  pill”  to  dilute  the  stock  ownership of  a
potential hostile acquirer to prevent an acquisition that is not approved by our board of directors.

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law, which may prohibit certain business
combinations  with  stockholders  owning  15%  or  more  of  our  outstanding  voting  stock. Any  delay  or  prevention  of  a  change  in  control
transaction or changes in our board of directors could cause the market price of our common stock to decline.

We do not intend to pay cash dividends.

We have never declared or paid cash dividends on our capital stock and we do not anticipate paying any cash dividends in the foreseeable
future. We currently intend to retain all available funds and any future earnings for debt service and use in the operation and expansion of
our business. The Loan and Security Agreement contains a negative covenant which prohibits us from paying dividends to our stockholders
without the prior written consent of Hercules Technology. In addition, the terms of any future debt or credit facility may preclude us from
paying any dividends.

Risks Related to Public Companies

We  are  an  “emerging  growth  company”  as  defined  in  the  Jumpstart  Our  Business  Startups  Act  of  2012  and  a  “smaller  reporting
company”  and  the  reduced  disclosure  requirements  applicable  to  emerging  growth  companies  and  smaller  reporting  companies  may
make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as long as we
continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable
to other public companies that are not emerging growth companies, including (1) not being required to comply with the auditor attestation
requirements  of  Section  404  of  the  Sarbanes-Oxley  Act,  (2)  reduced  disclosure  obligations  regarding  executive  compensation  in  our
periodic  reports  and  proxy  statements  and  (3)  exemptions  from  the  requirements  of  holding  a  nonbinding  advisory  vote  on  executive
compensation  and  stockholder  approval  of  any  golden  parachute  payments  not  previously  approved. Additionally,  under  the  JOBS Act,
emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private
companies. We are electing to delay such adoption of new or revised accounting standards on the relevant dates on which adoption of such
standards is required for non-emerging growth companies. As a result of this election, our financial statements may not be comparable to
the financial statements of other public companies.

We may take advantage of these exemptions until we are no longer an emerging growth company. Under the JOBS Act, we may be able to
maintain emerging growth company status for up to five years, although circumstances could cause us to lose that status earlier, including if
the market value of our common stock held by non-affiliates exceeds $700.0 million as of any June 30 before the end of such five-year
period or if we have total annual gross revenue of $1.0 billion or more during any fiscal year before that time, in which cases we would no
longer  be  an  emerging  growth  company  as  of  the  following  December  31.  Additionally,  if  we  issue  more  than  $1.0  billion  in  non-
convertible debt during any three-year period before that time, we would cease to be an emerging growth company immediately.

We are also currently a “smaller reporting company” as defined in the Securities Exchange Act of 1934, and in the event that we are still
considered  a  smaller  reporting  company  at  such  time  as  we  cease  being  an  emerging  growth  company,  we  will  be  required  to  provide
additional disclosure in our SEC filings. However, similar to emerging growth companies, smaller reporting companies are able to provide
simplified executive compensation disclosures in their filings, are exempt from the provisions of Section 404(b) of the Sarbanes-Oxley Act
requiring  that  independent  registered  public  accounting  firms  provide  an  attestation  report  on  the  effectiveness  of  internal  control  over
financial reporting, and have certain other decreased disclosure obligations in their SEC filings, including, among other things, only being
required to provide two years of audited financial statements in annual reports. We cannot predict whether investors will find our common
stock less attractive because of our reliance on any of these exemptions. If some investors find our common stock less attractive as a result,
there may be a less active trading market for our common stock and our stock price may be more volatile.

We could be delisted from Nasdaq, which could seriously harm the liquidity of our stock and our ability to raise capital.

On  January  2,  2018,  the  Company  received  a  notification  from  the  Listing  Qualifications  Department  of  Nasdaq  indicating  that  the
Company is not in compliance with Nasdaq Listing Rule 5620(a) due to its failure to hold an annual meeting of shareholders within twelve
months  of  the  end  of  the  Company’s  fiscal  year  ended  December  31,  2016.  On  February  16,  2018,  we  submitted  a  plan  to  regain
compliance. Our plan was accepted by Nasdaq and we now have until June 29, 2018, to regain compliance. There can be no assurance that
the  Company  will  be  able  to  regain  compliance  with  Nasdaq  requirements  or  will  otherwise  be  in  compliance  with  other  Nasdaq  listing
criteria.

If we cease to be eligible to trade on the Nasdaq Capital Market:

● We may have to pursue trading on a less recognized or accepted market, such as the OTC Bulletin Board or the “pink sheets.”

● The trading price of our common stock could suffer, including an increased spread between the “bid” and “asked” prices quoted by

market makers.

● Shares of our common stock could be less liquid and marketable, thereby reducing the ability of stockholders to purchase or sell our
shares as quickly and as inexpensively as they have done historically. If our stock is traded as a “penny stock,” transactions in our
stock would be more difficult and cumbersome.

● We may be unable to access capital on favorable terms or at all, as companies trading on alternative markets may be viewed as less
attractive investments with higher associated risks, such that existing or prospective institutional investors may be less interested in,
or prohibited from, investing in our common stock. This may also cause the market price of our common stock to decline.

51

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  incur  substantial  costs  as  a  result  of  being  a  public  company  and  our  management  expects  to  devote  substantial  time  to  public
company compliance programs.

As a public company, we incur significant legal, insurance, accounting and other expenses, including costs associated with public company
reporting.  We  intend  to  invest  resources  to  comply  with  evolving  laws,  regulations  and  standards,  and  this  investment  will  result  in
increased  general  and  administrative  expenses  and  may  divert  management’s  time  and  attention  from  product  development  and
commercialization  activities.  If  our  efforts  to  comply  with  new  laws,  regulations  and  standards  differ  from  the  activities  intended  by
regulatory or governing bodies due to ambiguities related to practice, regulatory authorities may initiate legal proceedings against us, and
our  business  may  be  harmed.  These  laws  and  regulations  could  make  it  more  difficult  and  costly  for  us  to  obtain  director  and  officer
liability insurance for our directors and officers, and we may be required to accept reduced coverage or incur substantially higher costs to
obtain  coverage.  These  factors  could  also  make  it  more  difficult  for  us  to  attract  and  retain  qualified  executive  officers  and  qualified
members of our board of directors, particularly to serve on our audit and compensation committees. In addition, if we are unable to continue
to meet the legal, regulatory and other requirements related to being a public company, we may not be able to maintain the listing of our
common stock on The NASDAQ Capital Market, which would likely have a material adverse effect on the trading price of our common
stock.

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

OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated
financial statements and related notes appearing elsewhere in this Annual Report. This discussion and analysis contains forward-looking
statements  based  upon  current  beliefs,  plans,  expectations,  intentions  and  projections  that  involve  risks,  uncertainties  and  assumptions,
such as statements regarding our plans, objectives, expectations, intentions and projections. Our actual results and the timing of selected
events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set
forth under “Risk Factors” and elsewhere in this Annual Report.

Overview

We are a materials company focused on developing, manufacturing and selling silicon nitride ceramics that are used in medical implants
and in a variety of industrial devices. At present, we commercialize silicon nitride in the spine implant market. We believe that our facile
silicon  nitride  manufacturing  expertise  positions  us  favorably  to  introduce  new  and  innovative  devices  in  the  medical  and  non-medical
fields. We also believe that we are the first and only company to commercialize silicon nitride medical implants.

We have received 510(k) regulatory clearance in the United States, a CE mark in Europe, and ANVISA approval in Brazil for a number of
our devices that are designed for spinal fusion surgery. To date, more than 28,000 of our silicon nitride devices have been implanted into
patients,  with  an  8-year  successful  track  record.  In  December  2016,  we  re-filed  an  FDA  510(k)  submission  for  clearance  in  the  United
States of a modified novel composite spinal fusion device that combines porous and solid silicon nitride and obviates the need for bone
grafts that is comparable to our commercially-available Valeo®C cervical implants.

We  believe  that  silicon  nitride  has  a  superb  combination  of  properties  that  make  it  ideally  suited  for  human  implantation.  Other
biomaterials are based on bone grafts, metal alloys, and polymers; all of which have practical limitations. In contrast, silicon nitride has a
legacy  of  success  in  the  most  demanding  and  extreme  industrial  environments. As  a  human  implant  material,  silicon  nitride  offers  bone
ingrowth, resistance to bacterial infection, resistance to corrosion, superior strength and fracture resistance, and ease of diagnostic imaging,
among other advantages.

We market and sell our Valeo brand of silicon nitride implants to surgeons and hospitals in the United States and to selected markets in
Europe  and  South America  through  more  than  50  independent  sales  distributors  who  are  supported  by  an  in-house  sales  and  marketing
management  team.  These  implants  are  designed  for  use  in  cervical  (neck)  and  thoracolumbar  (lower  back)  spine  surgery.  In  2016  we
entered into a 10-year exclusive distribution agreement with Shandong Weigao Orthopaedic Device Company Limited (“Weigao”) to sell
Amedica-branded  silicon  nitride  spinal  fusion  devices  within  the  People’s  Republic  of  China  (“China”).  Weigao,  a  large  orthopedic
company, has expertise in acquiring Chinese Food and Drug Administration (“CFDA”) approval of medical devices, and will assist us in
obtaining regulatory approval. Weigao has committed to minimum purchase requirements totaling 225,000 implants in the first six years
following  CFDA  clearance.  We  are  also  working  with  other  partners  in  Japan  to  obtain  regulatory  approval  for  silicon  nitride  in  that
country. China and Japan are relevant because historically, ceramic implants are more familiar to, and more readily accepted by surgeons
outside the United States, i.e., in Asia and Europe.

In addition to silicon nitride, we also sell metal-based products in the United States that provide surgeons and hospitals with a complete
package  for  spinal  surgery.  These  metal  products  are  designed  to  address  spinal  deformity  and  degenerative  conditions. Although  these
metal products have accounted for approximately 53% and 48% of our product revenues for the years ended December 31, 2017 and 2016,
respectively, we remain focused on developing and promoting silicon nitride, and driving its adoption through a scientifically-intense, data-
driven strategy.

In addition to direct sales, we have targeted original equipment manufacturer (“OEM”) and private label partnerships in order to accelerate
adoption  of  silicon  nitride,  both  in  the  spinal  space,  and  also  in  future  markets  such  as  hip  and  knee  replacements,  dental,  extremities,
trauma,  and  sports  medicine.  Existing  biomaterials,  based  on  plastics,  metals,  and  bone  grafts  have  well-recognized  limitations  that  we
believe  are  addressed  by  silicon  nitride,  and  we  are  uniquely  positioned  to  convert  existing,  successful  implant  designs  made  by  other
companies into silicon nitride. We believe OEM and private label partnerships will allow us to work with a variety of partners, accelerate
the adoption of silicon nitride, and realize incremental revenue at improved operating margins, when compared to the cost-intensive direct
sales model.

54

 
 
 
 
 
 
 
 
 
We  believe  that  silicon  nitride  addresses  many  of  the  biomaterial-related  limitations  in  fields  such  as  hip  and  knee  replacements,  dental
implants, sports medicine, extremities, and trauma surgery. We further believe that the inherent material properties of silicon nitride, and
the ability to formulate the material in a variety of compositions, combined with precise control of the surface properties of the material,
opens up a number of commercial opportunities across orthopedic surgery, neurological surgery, maxillofacial surgery, and other medical
disciplines.

We operate a 30,000 square foot manufacturing facility at our corporate headquarters in Salt Lake City, Utah, and we believe we are the
only vertically integrated silicon nitride medical device manufacturer in the world.

Components of our Results of Operations

We  manage  our  business  within  one  reportable  segment,  which  is  consistent  with  how  our  management  reviews  our  business,  makes
investment and resource allocation decisions and assesses operating performance.

Product Revenue

We derive our product revenue primarily from the sale of spinal fusion and fixation devices and related products used in the treatment of
spine  disorders.  Our  product  revenue  is  generated  from  sales  to  three  types  of  customers:  (1)  surgeons  and  hospitals;  (2)  stocking
distributors; and (3) private label customers. Most of our products are sold on a consignment basis through a network of independent sales
distributors;  however,  we  also  sell  our  products  to  independent  stocking  distributors  and  private  label  customers.  Product  revenue  is
recognized when all four of the following criteria are met: (1) persuasive evidence that an arrangement exists; (2) delivery of the products
has  occurred;  (3)  the  selling  price  of  the  product  is  fixed  or  determinable;  and  (4)  collectability  is  reasonably  assured.  We  generate  the
majority of our revenue from the sale of inventory that is consigned to independent sales distributors that sell our products to surgeons and
hospitals.  For  these  products,  we  recognize  revenue  at  the  time  we  are  notified  the  product  has  been  used  or  implanted  and  all  other
revenue  recognition  criteria  have  been  met.  For  all  other  transactions,  we  recognize  revenue  when  title  and  risk  of  loss  transfer  to  the
stocking distributor or private label customers, and all other revenue recognition criteria have been met. We generally recognize revenue
from sales to stocking distributors and private label customers at the time the product is shipped to the distributor. Stocking distributors and
private  label  customers,  who  sell  the  products  to  their  customers,  take  title  to  the  products  and  assume  all  risks  of  ownership  at  time  of
shipment. Our stocking distributors and private label customers are obligated to pay within specified terms regardless of when, if ever, they
sell  the  products.  Our  policy  is  to  classify  shipping  and  handling  costs  billed  to  customers  as  an  offset  to  total  shipping  expense  in  the
statement of operations, primarily within sales and marketing. In general, our customers do not have any rights of return or exchange.

We believe our product revenue will increase due to our sales and marketing efforts and as we continue to introduce new products into the
market. We expect that our product revenue will continue to be primarily attributable to sales of our products in the United States.

Cost of Revenue

The expenses that are included in cost of revenue include all direct product costs if we obtained the product from third-party manufacturers
and  our  in-house  manufacturing  costs  for  the  products  we  manufacture.  We  obtain  our  non-silicon  nitride  products,  including  our  metal
products, from third-party manufacturers, while we currently manufacture our silicon-nitride products in-house.

Specific provisions for excess or obsolete inventory are also included in cost of revenue. In addition, we pay royalties attributable to the sale
of specific products to some of our surgeon advisors that assisted us in the design, regulatory clearance or commercialization of a particular
product. These payments are recorded as cost of revenue. In addition, during 2016 we incurred impairment charges relating to the ceramic
equipment used to manufacture implants.

55

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Gross Profit

Our gross profit measures our product revenue relative to our cost of revenue. We expect our gross profit to decrease as we expand the
penetration of our silicon nitride technology platform through OEM and private label partnerships, which offer additional avenues for the
adoption of silicon nitride, but they are not an area of focus at the moment.

Research and Development Expenses

Our  research  and  development  costs  are  expensed  as  incurred.  Research  and  development  costs  consist  of  engineering,  product
development, clinical trials, test-part manufacturing, testing, developing and validating the manufacturing process, manufacturing, facility
and regulatory-related costs. Research and development expenses also include employee compensation, employee and non-employee stock-
based  compensation,  supplies  and  materials,  consultant  services,  and  travel  and  facilities  expenses  related  to  research  activities.  To  the
extent  that  certain  research  and  development  expenses  are  directly  related  to  our  manufactured  products,  such  expenses  and  related
overhead costs are allocated to inventory.

We expect to incur additional research and development costs as we continue to develop new spinal fusion products, our product candidates
for  total  joint  replacements,  such  as  our  total  hip  replacement  product  candidate,  and  dental  applications  which,  may  increase  our  total
research and development expenses.

Sales and Marketing Expenses

Sales  and  marketing  expenses  consist  of  salaries,  benefits  and  other  related  costs,  including  stock-based  compensation,  for  personnel
employed  in  sales,  marketing,  medical  education  and  training.  In  addition,  our  sales  and  marketing  expenses  include  commissions  and
bonuses, generally based on a percentage of sales, to our sales managers and independent sales distributors. We provide our products in kits
or banks that consist of a range of device sizes and separate instruments sets necessary to perform the surgical procedure. We generally
consign our instruments to our distributors or our hospital customers that purchase the device used in spinal fusion surgery. Our sales and
marketing expenses include depreciation (and for 2016, impairment charges) of the surgical instruments.

We  expect  our  commissions  to  increase  in  absolute  terms  over  time  but  remain  approximately  the  same  or  decrease  as  a  percentage  of
product revenue.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries, benefits and other related costs, including stock-based compensation for
certain members of our executive team and other personnel employed in finance, legal, compliance, administrative, information technology,
customer service, executive and human resource departments. General and administrative expenses also include other expenses not part of
the other cost categories mentioned above, including facility expenses and professional fees for accounting and legal services. In addition,
during 2016 we incurred impairment charges relating to leasehold improvements.

We expect our general and administrative expenses to remain stable or slightly decline as we continue to manage costs closely and look for
opportunities to make improvements.

Reverse Stock Split

On  November  10,  2017,  the  Company  effected  a  1  for  12  reverse  stock  split  of  the  Company’s  common  stock.  The  par  value  and  the
authorized shares of the common and convertible preferred stock were not adjusted as a result of the reverse stock split. All common stock
share and per-share amounts for all periods presented in the accompanying consolidated financial statements prior to November 10, 2017
have been adjusted retroactively to reflect the reverse stock split.

Total product revenue was $11.2 million in 2017 as compared to $15.2 million in 2016, a decrease of $4.0 million or 26%. This decline was
due  to  silicon  nitride  sales  decreasing  by  $2.6  million,  or  33%,  and  non-silicon  nitride  sales  decreasing  by  $1.4  million,  or  19%,  as
compared to the same period in 2016. This decrease was primarily due to the loss of surgeons and the consequences from our restructuring,
both of which occurred during the latter part of 2016.

International  revenue  decreased  in  2017  as  compared  to  2016.  This  is  due  to  our  Brazilian  distributor  moving  from  building  inventory
during 2016 to maintaining inventory levels during the same period in 2017.

Costs of Revenue and Gross Profit

Our cost of revenue increased $2.6 million, or 68%, as compared to the same period in 2016 even though our sales decreased. The increase
was  primarily  due  to  an  increase  in  the  provision  for  inventory  reserve  of  $3.4  million.  Gross  profit  decreased  $6.6  million,  or  57%,
primarily due to the increase in the provision for inventory reserve.

Research and Development Expenses

Research and development expenses decreased $1.3 million, or 20%, as compared to the same period in 2016. This decrease was primarily
due to a $0.8 million reduction in personnel related expenses related to the October 2016 reduction in force and a $0.5 million decrease in
other misc. accounts.

General and Administrative Expenses

General and administrative expenses decreased $1.9 million, or 30%, as compared to the same period in 2016. This decrease was primarily
due to a $0.9 million decrease in personnel related expenses related to the October 2016 reduction in force, a $1.0 million decrease in legal
and  patent  expenses,  a  $0.1  million  decrease  in  investor  relations  expenses  and  the  Company’s  efforts  to  reduce  costs  and  $0.2  million
reduction in impairment on leasehold improvements, offset by $0.3 million increase in accounting and consulting fees.

Sales and Marketing Expenses

Sales and marketing expenses decreased $3.9 million, or 37%, as compared to the same period in 2016. This decrease was primarily due to
a  $1.4  million  decrease  in  commissions,  a  $0.6  million  decrease  in  personnel  related  expenses  related  to  the  October  2016  reduction  in
force, a $1.2 million decrease in depreciation expense, a $0.5 million decrease in impairment of instrument sets and a $0.2 million decrease
in other accounts.

Deemed Dividend

Deemed dividend in 2016 related to a beneficial conversion feature and accretion of discount on convertible preferred stock valued at $6.3
million  in  2016,  compared  to  none  for  2017. A  beneficial  conversion  amount  was  calculated  in  association  with  the  2016  issuance  of
certain convertible preferred stock and warrants that could convert to common stock at a discount below the trading price on the date of
issuance. The preferred stock was converted to common stock during 2016. No such stock was issued or converted during 2017.

Other Income (Expense), Net

Other expenses decreased $5.0 million, or 153%, as compared to the same period in 2016. This decrease was primarily due to a $3.2 million
decrease in interest expense, a $0.6 million increase on gain in fair value of derivative liabilities, a $0.4 million decrease in offering costs
and a $0.7 million decrease in expense due to the extinguishment of debt.

Liquidity and Capital Resources

The consolidated financial statements have been prepared assuming we will continue to operate as a going concern, which contemplates the
realization  of  assets  and  settlement  of  liabilities  in  the  normal  course  of  business,  and  does  not  include  any  adjustments  to  reflect  the
possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from
uncertainty related to its ability to continue as a going concern within one year from the date of issuance of these consolidated financial
statements.

For the years ended December 31, 2017 and 2016, we incurred a net loss of $9.3 million and $14.8 million, respectively, and used cash in
operations  of  $4.7  million  and  $7.2  million,  respectively.  We  had  an  accumulated  deficit  of  $220.6  million  and  $211.3  million  as  of
December  31,  2017  and  2016,  respectively.  To  date,  our  operations  have  been  principally  financed  from  proceeds  from  the  issuance  of
preferred and common stock, convertible debt and bank debt and, to a lesser extent, cash generated from product sales. It is anticipated that
we will continue to generate operating losses in the foreseeable future and use cash in operations. Our continuation as a going concern is
dependent  upon  its  ability  to  increase  sales,  implement  cost  saving  measures,  maintain  compliance  with  debt  covenants  and/or  raise
additional  funds  through  the  capital  markets.  Whether  and  when  we  can  attain  profitability  and  positive  cash  flows  from  operations  or
obtain additional financing is uncertain.

In 2016 we implemented certain cost saving measures, including workforce and office space reductions, and have continued to evaluate
additional cost savings alternatives during 2017. These additional cost savings measures may include additional workforce and research and
development reductions, as well as cuts to certain other operating expenses. In addition to these cost saving measures an experienced and
highly  successful  leader  for  the  Sales  and  Marketing  team  was  recruited  and  hired.  This  individual  has  subsequently  hired  additional
experienced  personnel  in  Sales  and  Market  Development.  We  are  actively  generating  additional  scientific  and  clinical  data  to  have  it
published in leading industry publications. The unique features of our silicon nitride material are not well known, and such the publication
of such data would help sales efforts as we approach new prospects. We are also making additional changes to the sales strategy, including
a focus on revenue growth of silicon nitride lateral lumbar implants and the newly developed pedicle screw system (known as Taurus).

On July 28, 2017, we entered into a $2.5 million term loan with a related party. We have common stock that is publicly traded and have
been able to successfully raise capital when needed since the date of our initial public offering. Subsequent to December 31, 2017, we were
able to raise equity funding through the exercise of outstanding warrants (see Note 13). We are engaged in discussions with investment and
banking firms to examine financing alternatives, including options for a public offering of our preferred or common stock.

Although we are seeking to obtain additional equity and/or debt financing, such funding is not assured and may not be available to us on
favorable or acceptable terms and may involve significant restrictive covenants. Any additional equity financing is also not assured and, if
available to us, will most likely be dilutive to its current stockholders. If we are not able to obtain additional debt or equity financing on a
timely basis, the impact on us will be material and adverse.

These uncertainties create substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not
include any adjustments that might result from the outcome of these uncertainties.

Cash Flows

The following table summarizes, for the periods indicated, cash flows from operating, investing and financing activities (in thousands):

Net cash used in operating activities was $4.7 million in 2017, compared to $7.2 million used in 2016, a decrease of $2.5 million. Offset by
the decrease in the net loss, and related non-cash add backs to the net loss, the decrease in cash used for operating activities during 2017
was primarily due to changes in the movement of working capital items during 2017 as compared to the same period in 2016 as follows: a
$0.7 million decrease in trade accounts receivable, a $0.1 increase in prepaid expenses and other current assets, a $0.5 million decrease in
inventories and a $1.1 million increase in accounts payable and accrued liabilities.

Net Cash Provided by Investing Activities

Net cash used in investing activities was $1.1 million during 2017, compared to $0.6 million used in investing activities during the same
period in 2016, an increase of $0.5 million. The increase in cash used in investing activities during 2017 was due to increased purchases of
property and equipment.

Net Cash Provided by Financing Activities

Net cash used in financing activities was $0.6 million during 2017, compared to $3.2 million provided during the same period in 2016, an
increase of $3.8 million. The $3.8 million increase in 2017 was primarily due to a $3.0 million decrease in cash generated from the issuance
of common and preferred stock, a $4.6 million decrease in cash generated from the issuance of derivative warrant liabilities, which was
offset by an increase in net debt proceeds of $4.0 million.

North Stadium Term Loan

On  July  28,  2017,  we  entered  into  a  $2.5  million  term  loan  (the  “North  Stadium  Loan”)  with  North  Stadium  Investments,  LLC  (“North
Stadium”), a company owned and controlled by our Chief Executive Officer and Chairman of the Board. The North Stadium Loan bears
interest  at  10%  per  annum  and  requires  us  to  make  monthly  interest  only  payments  from  September  5,  2017  through  July  5,  2018. All
principal  and  unpaid  interest  (if  any)  under  the  North  Stadium  Loan  is  due  and  payable  on  July  28,  2018.  The  North  Stadium  Loan  is
secured by substantially all of the assets of the Company and is junior to security interest in assets encumbered by the Hercules Term Loan
(see below). In connection with the North Stadium Loan we also issued North Stadium a warrant to purchase up to 55,000 shares of our
common stock at a purchase price of $5.04 per share, subject to a 5-year term. The relative estimated value of the warrants on the date of
grant approximated $0.2 million, which is being amortized as interest expense over the life of the term loan.

Hercules Term Loan

On June 30, 2014, we entered into a Loan and Security Agreement with Hercules which provided us with a $20.0 million term loan. The
Hercules  Term  Loan  matured  on  January  1,  2018.  The  Hercules  Term  Loan  included  a  $0.2  million  closing  fee,  which  was  paid  to
Hercules on the closing date of the loan. The closing fee was recorded as a debt discount and is being amortized to interest expense over
the life of the loan. The Hercules Term Loan also includes a non-refundable final payment fee of $1.7 million. The final payment fee is
being accrued and recorded to interest expense over the life of the loan. The Hercules Term Loan bears interest at the rate of the greater of
either (i) the prime rate plus 7.7%, and (ii) 10.95%, provided however, that during an adjustment period, the term loan interest rate shall
mean for any day a per annum rate of interest equal to the grater of either (i) the prime rate plus 9.2%, and (ii) 12.45%. The applicable rate
was 11.95% as of December 31, 2017. Interest accrues from the closing date of the loan and interest payments are due monthly. Principal
payments  commenced August  1,  2015  and  are  currently  being  made  in  equal  monthly  installments  totaling  approximately  $0.5  million,
with the remainder due at maturity. The Hercules Term Loan is secured by a first priority security interest in substantially all of its assets,
including  intellectual  property,  of  us  and  contains  covenants  restricting  our  payments  to  certain  affiliates  and  certain  financial  reporting
requirements.

On  September  8,  2015,  we  entered  into  a  Consent  and  First  Amendment  to  Loan  and  Security  Agreement  (the  “Amendment”)  with
Hercules.  The Amendment  modified  the  liquidity  covenant  to  reduce  the  required  minimum  cash  and  cash  equivalents  balance  by  $0.5
million for every $1.0 million in principal paid, up to a minimum of $2.5 million. Once the Hercules Term Loan principal balance is below
$2.5  million  we  are  only  required  to  maintain  a  cash  and  cash  equivalents  balance  equal  to  the  outstanding  principal  balance  on  the
Hercules  Term  loan.  The  minimum  cash  and  cash  equivalents  balance  required  to  maintain  compliance  with  the  minimum  liquidity
covenant as of December 31, 2017, was approximately $0.6 million. Subsequent to December 31, 2017, the Hercules term loan was paid in
full.

See  discussion  below  with  respect  to  the  assignment  of  $3.0  million  of  the  principal  balance  of  the  Hercules  Term  Loan  to  Riverside
Merchant  Partners,  LLC  (“Riverside”)  and  the  subsequent  agreement  between  us  and  Riverside  to  exchange  the  $3.0  million  of  the
Hercules Term Loan held by Riverside for subordinated convertible promissory notes in the aggregate principal amount of $3.0 million.

Hercules and Riverside Debt Exchange

On April 4, 2016, we entered into an Assignment and Second Amendment to Loan and Security Agreement (the “Assignment Agreement”)
with Riverside and Hercules, pursuant to which Hercules sold $1.0 million of the principal amount outstanding under the Hercules Term
Loan to Riverside. In addition, pursuant to the terms of the Assignment Agreement, Riverside acquired an option to purchase an additional
$2.0 million of the principal amount outstanding under the Hercules Term Loan from Hercules. On April 18, 2016, Riverside exercised and
purchased an additional $1.0 million of the principal amount of the Hercules Term Loan and on April 27, 2016, Riverside exercised the
remainder of its option and purchased an additional $1.0 million of the principal amount of the Hercules Term Loan from Hercules.

Riverside Debt

On April 4, 2016, we entered into an exchange agreement (the “Exchange Agreement”) with Riverside, pursuant to which we agreed to
exchange $1.0 million of the principal amount outstanding under the Hercules Term Loan held by Riverside for a subordinated convertible
promissory note in the principal amount of $1.0 million (the “First Exchange Note”) and a warrant to purchase 8,333 shares of common
stock of ours at a fixed exercise price of $19.56 per share (the “First Exchange Warrant”) (the “Exchange”). All principal accrued under the
Exchange Notes was convertible into shares of common stock at the election of the Holder at any time at a fixed conversion price of $17.16
per share (the “Conversion Price”). The closing stock price on April 4, 2016, was $19.56 and a beneficial conversion feature of $0.2 million
was recorded to equity and as a debt discount. The warrant value of $0.1 million was recorded to equity and as a debt discount.

In  addition,  pursuant  to  the  terms  and  conditions  of  the  Exchange Agreement,  ourselves  and  Riverside  had  the  option  to  exchange  an
additional $2.0 million of the principal amount of the Hercules Term Loan for an additional subordinated convertible promissory note in
the principal amount of up to $2.0 million and an additional warrant to purchase 8,333 shares of common stock (the “Second Exchange
Warrant”).  The  Exchange Agreement  also  provided  that  if  the  volume-weighted  average  price  of  our  common  stock  was  less  than  the
Conversion  Price,  we  would  issue  up  to  an  additional  12,500  shares  of  common  stock  (the  “True-Up  Shares”)  to  Riverside,  which  was
subsequently reduced to 11,667 shares of common stock.

On April 18, 2016, ourselves and Riverside exercised their option to exchange an additional $1.0 million of the principal amount of the
Hercules  Term  Loan  for  an  additional  subordinated  convertible  promissory  note  in  the  principal  amount  of  $1.0  million  (the  “Second
Exchange Note”). The closing stock price on April 18, 2016, was $24.24 and a beneficial conversion feature of $0.4 million was recorded
to equity and as a debt discount. Additionally, on April 27, 2016, ourselves and Riverside exercised their option to exchange an additional
$1.0 million of the principal amount of the Term Loan for an additional subordinated convertible promissory note in the principal amount
of $1.0 million (the “Third Exchange Note”) and an additional warrant to purchase 8,333 shares of our common stock at a fixed exercise
price of $19.92 per share. The warrant value of $0.1 million was recorded to equity and as a debt discount. The closing stock price on April
27, 2016, was $19.92 and a beneficial conversion feature of $0.3 million was recorded to equity and as a debt discount. Financing costs
were $0.3 million and were recorded to interest expense. The unamortized deferred financing costs and debt discount of the Hercules Term
Loan exchanged were $0.2 million at the time of the exchange and were recorded as a loss on extinguishment of debt related to the debt
exchange.  The  First  Exchange  Note,  the  Second  Exchange  Note  and  the  Third  Exchange  Note  are  collectively  referred  to  herein  as  the
“Exchange Notes.”

Pursuant to the terms of the Exchange Notes, since the volume-weighted average price of our common stock was less than the Conversion
Price on May 6, 2016, we issued an additional 11,667 shares of common stock to Riverside and recorded the value of the True-Up Shares
of $0.2 million to interest expense and equity.

All principal outstanding under each of the Exchange Notes was to be due on April 3, 2018 (the “Maturity Date”). Each of the Exchange
Notes bore interest at a rate of 6% per annum, with the interest that would accrue on the initial principal amount of the Exchange Notes
during the first 12 months being guaranteed and deemed earned as of the date of issuance. Prior to the Maturity Date, all interest accrued
under the Exchange Notes was payable in cash or, if certain conditions were met, payable in shares of common stock at our option, at a
conversion price of $16.08 per share. During 2016, the entire principal amount of the First and Second Exchange Notes, $0.3 million of the
Third  Exchange  Note,  and  the  interest  related  to  the  First,  Second,  and  Third  Exchange  Notes  was  converted  into  145,227  shares  of
common stock. In July 2016, we paid Riverside $0.8 million to redeem in full the remaining principal balance of the Third Exchange Note.
The debt discounts associated with the converted debt was recorded to interest expense.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as defined in Item 303(a)(4) of Regulation S-K.

Related-Party Transactions

For a description of our related-party transactions, see “Certain Relationships and Related Party Transactions.”

Seasonality and Backlog

Our business is generally not seasonal in nature. Our sales generally consist of products that are in stock with us or maintained at hospitals
or with our sales distributors. Accordingly, we do not have a backlog of sales orders.

Critical Accounting Policies and Estimates

A  summary  of  our  significant  accounting  policies  and  estimates  is  discussed  in  Management’s  Discussion  and  Analysis  of  Financial
Condition and Results of Operations and in Note 1 to our consolidated financial statements included in our Annual Report on Form 10-K
for the year ended December 31, 2016. There have been no material changes to those policies for the year ended December 31, 2017. The
preparation of the consolidated financial statements in accordance with U.S. generally accepted accounting principles requires us to make
judgments, estimates and assumptions regarding uncertainties that affect the reported amounts of assets and liabilities. Significant areas of
uncertainty that require judgments, estimates and assumptions include the accounting for income taxes and other contingencies as well as
valuation of derivative liabilities, asset impairment and collectability of accounts receivable. We use historical and other information that
we  consider  to  be  relevant  to  make  these  judgments  and  estimates.  However,  actual  results  may  differ  from  those  estimates  and
assumptions that are used to prepare our consolidated financial statements.

Revenue Recognition

We  derive  our  product  revenue  primarily  from  the  sale  of  spinal  fusion  devices  and  related  products  used  in  the  treatment  of  spine
disorders. Our product revenue is generated from sales to three types of customers: (1) surgeons and hospitals; (2) stocking distributors; and
(3)  private  label  customers.  Most  of  our  products  are  sold  on  a  consignment  basis  through  a  network  of  independent  sales  distributors;
however, we also sell our products to independent stocking distributors and private label customers. Product revenue is recognized when all
four of the following criteria are met: (1) persuasive evidence that an arrangement exists; (2) delivery of the products has occurred; (3) the
selling price of the product is fixed or determinable; and (4) collectability is reasonably assured. We generate the majority of our revenue
from the sale of inventory that is consigned to independent sales distributors that facilitate sales of our products to surgeons and hospitals.
For  these  products,  we  recognize  revenue  at  the  time  we  are  notified  the  product  has  been  used  or  implanted  and  all  other  revenue
recognition  criteria  have  been  met.  For  all  other  transactions,  we  recognize  revenue  when  title  and  risk  of  loss  transfer  to  the  stocking
distributor or private label customer, and all other revenue recognition criteria have been met. We generally recognize revenue from sales
to stocking distributors at the time the product is shipped to the distributor. Stocking distributors, who sell the products to their customers,
take  title  to  the  products  and  assume  all  risks  of  ownership  at  time  of  shipment.  Our  stocking  distributors  are  obligated  to  pay  within
specified terms regardless of when, if ever, they sell the products. In general, our customers do not have any rights of return or exchange.

Accounts Receivable and Allowance for Doubtful Accounts

The majority of our accounts receivable is composed of amounts due from hospitals or surgical centers. Accounts receivable are carried at
invoiced amount less an allowance for doubtful accounts. On a regular basis, we evaluate accounts receivable and estimate an allowance for
doubtful accounts, as needed, based on various factors such as customers’ current credit conditions, length of time past due, and the general
economy as a whole. Receivables are written off against the allowance when they are deemed uncollectible.

63

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Inventories

Inventories are stated at the lower of cost or net realizable value, with cost for manufactured inventory determined under the standard costs,
which  approximate  actual  costs,  determined  on  the  first-in  first-out  (“FIFO”)  method.  Manufactured  inventory  consists  of  raw  material,
direct labor and manufacturing overhead cost components. Inventories purchased from third-party manufacturers are stated at the lower of
cost  or  market  using  the  first-in,  first-out  method.  We  review  the  carrying  value  of  inventory  on  a  periodic  basis  for  excess  or  obsolete
items, and records any write-down as a cost of revenue, as necessary. It is reasonably possible that we may be required to make adjustments
to  the  carrying  value  of  inventory  in  future  periods.  Inventory  write-downs  for  excess  or  obsolete  inventory  are  recorded  as  a  cost  of
revenue.  We  hold  consigned  inventory  at  distributor  and  other  customer  locations  where  revenue  recognition  criteria  have  not  yet  been
achieved.

Long-Lived Assets and Goodwill

We periodically evaluate the carrying value of definite-lived intangibles when events or changes in circumstances indicate that the carrying
value  may  not  be  recoverable.  Factors  we  consider  important  which  could  trigger  an  impairment  review  include,  but  are  not  limited  to,
significant  under-performance  relative  to  historical  or  projected  future  operating  results,  significant  changes  in  the  manner  of  its  use  of
acquired assets or its overall business strategy, and significant industry or economic trends. We amortize definite-lived intangible assets on
a  straight-line  basis  over  their  useful  lives.  We  record  no  impairment  loss  for  definite-lived  intangible  assets  during  the  years  ended
December 31, 2017 and 2016.

When we determine that the carrying value of a long-lived asset may not be recoverable based upon the existence of one or more of the
above indicators, we determine the recoverability by comparing the carrying amount of the asset to net future undiscounted cash flows that
the asset is expected to generate and recognizes an impairment charge equal to the amount by which the carrying amount exceeds the fair
market value of the asset.

If our revenues or other estimated operating results are not achieved at or above our forecasted level, and we are unable to recover such
costs  through  price  increases,  the  carrying  value  of  certain  of  our  assets  may  prove  to  be  unrecoverable  and  we  may  incur  impairment
charges of definitive-live intangible assets.

In  accordance  with  ASC  350,  Goodwill  and  Other  Intangible  Assets,  goodwill  is  not  amortized  but  is  required  to  be  reviewed  for
impairment  at  least  annually  or  when  events  or  circumstances  indicate  that  carrying  value  may  exceed  fair  value.  We  are  permitted  the
option to first assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than
not  that  the  fair  value  of  any  reporting  unit  is  less  than  its  corresponding  carrying  value.  If,  after  assessing  the  totality  of  events  and
circumstances, we conclude that it is not more likely than not that the fair value of any reporting unit is less than its corresponding carrying
value  then  we  are  not  required  to  take  further  action.  However,  if  we  conclude  otherwise,  then  it  is  required  to  perform  a  quantitative
impairment  test,  including  computing  the  fair  value  of  the  reporting  unit  and  comparing  that  value  to  its  carrying  value.  We  consider
valuation  factors  and  an  estimated  control  premium.  The  estimated  fair  value  of  the  reporting  unit  exceeded  the  carrying  value  as  of
December 31, 2017 and 2016. The declining price of our stock is an early indicator that goodwill impairment may be a factor during 2018.
We  will  continue  to  monitor  our  market  capitalization  and  impairment  indicators.  In  the  event  that  goodwill  is  impaired,  an  impairment
charge to earnings would become necessary.

If the fair value is less than its carrying value, a second step of the test is required to determine if recorded goodwill is impaired. In the
event that goodwill is impaired, an impairment charge to earnings would become necessary.

64

 
 
 
 
 
 
 
 
 
 
 
 
Property and Equipment

Property and equipment, including surgical instruments and leasehold improvements, are stated at cost, less accumulated depreciation and
amortization.  Property  and  equipment  are  depreciated  using  the  straight-line  method  over  the  estimated  useful  lives  of  the  assets,  which
range from three to five years. Leasehold improvements are amortized over the shorter of their estimated useful lives or the related lease
term, generally five years.

Periodically we review the carrying value of our property and equipment that are held and used in our operations for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is
determined based upon expected undiscounted future net cash flows from the operations to which the assets relate, utilizing management’s
best estimate, assumptions, and projections at the time. If the carrying value is determined to be unrecoverable from future operating cash
flows, the asset is deemed impaired and an impairment charge would be recognized to the extent the carrying value exceeded the estimated
fair value of the asset. We estimate the fair value of assets based on the estimated future discounted cash flows arising from the use of the
asset. Management has evaluated its property and equipment and identified specific asset impairments during the year ended December 31,
2016. No impairment was identified during the year ended December 31, 2017.

Income Taxes

We  recognize  deferred  tax  assets  and  liabilities  for  the  future  tax  consequences  attributable  to  the  differences  between  the  financial
statement  carrying  value  of  existing  assets  and  liabilities  and  their  respective  tax  bases.  Deferred  tax  assets  and  liabilities  are  measured
using enacted tax rates in effect for the fiscal year in which those temporary differences are expected to be recovered or settled. Valuation
allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

We operate in various tax jurisdictions and is subject to audit by various tax authorities. We provide for tax contingencies whenever it is
deemed probable that a tax asset has been impaired, or a tax liability has been incurred for events such as tax claims or changes in tax laws.
Tax  contingencies  are  based  upon  their  technical  merits  relative  tax  law  and  the  specific  facts  and  circumstances  as  of  each  reporting
period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax contingencies.

We recognize uncertain income tax positions taken on income tax returns at the largest amount that is more-likely than-not to be sustained
upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of
being sustained.

Our policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of our income
tax  provision.  For  the  years  ended  December  31,  2017  and  2016,  we  did  not  record  any  material  interest  income,  interest  expense  or
penalties related to uncertain tax positions or the settlement of audits for prior periods.

Stock-Based Compensation

We measure stock-based compensation expense related to employee stock-based awards based on the estimated fair value of the awards as
determined on the date of grant and is recognized as expense over the remaining requisite service period. We utilize the Black-Scholes-
Merton option pricing model to estimate the fair value of employee stock options. The Black-Scholes-Merton model requires the input of
highly subjective and complex assumptions, including the estimated fair value of our common stock on the date of grant, the expected term
of the stock option, and the expected volatility of our common stock over the period equal to the expected term of the grant. We estimate
forfeitures at the date of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
We  account  for  stock  options  to  purchase  shares  of  stock  that  are  issued  to  non-employees  based  on  the  estimated  fair  value  of  such
instruments  using  the  Black-Scholes-Merton  option  pricing  model.  The  measurement  of  stock-based  compensation  expense  for  these
instruments is variable and subject to periodic adjustments to the estimated fair value until the awards vest. Any resulting change in the
estimated fair value is recognized in our consolidated statements of operations during the period in which the related services are rendered.

Because we were a privately-held company with no trading history prior to February 2014 and have limited stock history since February
2014,  we  utilize  the  historical  stock  price  volatility  from  a  representative  group  of  public  companies  to  estimate  expected  stock  price
volatility and our historical stock price. We selected companies from the medical device industry, specifically those who are focused on the
design,  development  and  commercialization  of  products  for  the  treatment  of  spine  disorders,  and  who  have  similar  characteristics  to  us,
such  as  stage  of  life  cycle  and  size.  We  intend  to  continue  to  utilize  the  historical  volatility  of  the  same  or  similar  public  companies  to
estimate  expected  volatility  until  a  sufficient  amount  of  historical  information  regarding  the  price  of  our  publicly  traded  stock  becomes
available.  We  use  the  simplified  method  as  prescribed  by  the  Securities  and  Exchange  Commission  Staff Accounting  Bulletin  No.  107,
Share-based Payment, to calculate the expected term of stock option grants to employees as we do not have sufficient historical exercise
data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees. We utilize a dividend
yield of zero because we have never paid cash dividends and have no current intention to pay cash dividends. The risk-free rate of return
used for each grant is based on the U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life.

We  account  for  stock  options  to  purchase  shares  of  stock  that  are  issued  to  non-employees  based  on  the  estimated  fair  value  of  such
instruments  using  the  Black-Scholes-Merton  option  pricing  model.  The  measurement  of  stock-based  compensation  expense  for  these
instruments is variable and subject to periodic adjustments to the estimated fair value until the awards vest. Any resulting change in the
estimated fair value is recognized in our consolidated statements of operations during the period in which the related services are rendered.

Derivative Liabilities

Derivative liabilities include the fair value of instruments such as common stock warrants, preferred stock warrants and convertible features
of notes, that are initially recorded at fair value and are required to be re-measured to fair value at each reporting period under provisions of
ASC  480, Distinguishing  Liabilities  from  Equity,  or ASC  815, Derivatives and Hedging.  The  change  in  fair  value  of  the  instruments  is
recognized as a component of other income (expense) in our consolidated statements of operations until the instruments settle, expire or are
no  longer  classified  as  derivative  liabilities.  We  estimate  the  fair  value  of  these  instruments  using  the  Black-Scholes-Merton  or  Monte-
Carlo valuation models depending on the complexity of the underlying instrument. The significant assumptions used in estimating the fair
value include the exercise price, volatility of the stock underlying the instrument, risk-free interest rate, estimated fair value of the stock
underlying the instrument and the estimated life of the instrument.

New Accounting Pronouncement, Not Yet Adopted

In August 2016, the Financial Accounting Standards Board (“FASB”) updated accounting guidance on the following eight specific cash
flow classification issues: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon debt instruments or other debt
instruments  with  coupon  interest  rates  that  are  insignificant  in  relation  to  the  effective  interest  rate  of  the  borrowing;  (3)  contingent
consideration  payments  made  after  a  business  combination;  (4)  proceeds  from  the  settlement  of  insurance  claims;  (5)  proceeds  from  the
settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) distributions received from equity
method  investees;  (7)  beneficial  interests  in  securitization  transactions;  and  (8)  separately  identifiable  cash  flows  and  application  of  the
predominance principle. Current GAAP does not include specific guidance on these eight cash flow classification issues. These updates are
effective for us with its annual period beginning January 1, 2019, and interim periods therein, with early adoption permitted. The guidance
in this standard is not expected to have a material impact on the consolidated financial statements.

In  March  2016,  the  FASB  updated  the  accounting  guidance  related  to  stock  compensation.  This  update  simplifies  the  accounting  for
employee  share-based  payment  transactions,  including  the  accounting  for  income  taxes,  forfeitures,  and  statutory  tax  withholding
requirements, as the well as classification in the statement of cash flows. The standard is effective for us with its annual period beginning
January 1, 2018. The guidance in this standard is not expected to have a material impact on the consolidated financial statements for us.

66

 
 
 
 
 
 
 
 
 
 
 
In February 2016, the FASB updated the accounting guidance related to leases as part of a joint project with the International Accounting
Standards Board (“IASB”) to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities
on  the  balance  sheet  and  disclosing  key  information  about  leasing  arrangements.  Under  the  new  guidance,  a  lessee  will  be  required  to
recognize  assets  and  liabilities  for  capital  and  operating  leases  with  lease  terms  of  more  than  12  months. Additionally,  this  update  will
require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows
arising from leases, including qualitative and quantitative requirements. The standard is effective for us with its annual period beginning
January  1,  2020,  and  interim  periods  therein,  with  early  adoption  permitted.  We  are  currently  evaluating  the  potential  impact  this  new
standard may have on its consolidated financial statements but believes the most significant change will relate to building leases.

In May 2014, in addition to several amendments issued during 2016, the FASB updated the accounting guidance related to revenue from
contracts with customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle is that a
company  should  recognize  revenue  when  promised  goods  or  services  are  transferred  to  customers  in  an  amount  that  reflects  the
consideration to which an entity expects to be entitled for those goods or services. The standard defines a five-step process to achieve this
core  principle  and,  in  doing  so,  more  judgment  and  estimates  may  be  required  within  the  revenue  recognition  process  than  are  required
under existing U.S. GAAP. The standard is effective for us with the annual period beginning January 1, 2019, and interim periods therein,
and shall be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. We have
yet to begin evaluation of the new accounting standard and therefore has yet to determine the impact, if any, that the  new  standard  will
have on its consolidated financial statements.

In  January  of  2017,  the  FASB  issued ASU  2017-04—Intangibles—Goodwill  and  Other  (Topic  350):  Simplifying  the  Test  for  Goodwill
Impairment.  The  amendments  in  this  guidance  to  eliminate  the  requirement  to  calculate  the  implied  fair  value  of  goodwill  to  measure
goodwill impairment charge (Step 2). As a result, an impairment charge will equal the amount by which a reporting unit’s carrying amount
exceeds its fair value, not to exceed the amount of goodwill allocated to the reporting unit. An entity still has the option to perform the
qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendment should be applied
on a prospective basis. The guidance is effective for goodwill impairment tests in fiscal years beginning after December 15, 2021. Early
adoption is permitted for goodwill impairment tests performed after January 1, 2017. The impact of this guidance for us will depend on the
outcomes of future goodwill impairment tests.

We  have  reviewed  all  other  recently  issued,  but  not  yet  adopted,  accounting  standards,  in  order  to  determine  their  effects,  if  any,  on  its
results  of  operations,  financial  position  or  cash  flows.  Based  on  that  review,  we  believe  that  none  of  these  pronouncements  will  have  a
significant effect on its consolidated financial statements.

Jumpstart Our Business Startups Act of 2012

On April 5, 2012, the Jumpstart Our Business Startups Act of 2012, or JOBS Act, was enacted. Section 107 of the JOBS Act, provides that
an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of
1933, as amended, for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the
adoption of certain accounting standards until those standards would otherwise apply to private companies. We are electing to delay such
adoption  of  new  or  revised  accounting  standards,  and  as  a  result,  we  may  not  comply  with  new  or  revised  accounting  standards  on  the
relevant  dates  on  which  adoption  of  such  standards  is  required  for  non-emerging  growth  companies. As  a  result  of  this  election,  our
financial  statements  may  not  be  comparable  to  the  financial  statements  of  other  public  companies.  We  may  take  advantage  of  these
reporting exemptions until we are no longer an “emerging growth company.

67

 
 
 
 
 
 
 
 
 
 
We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements provided by the JOBS
Act.  Subject  to  certain  conditions  set  forth  in  the  JOBS Act,  as  an  “emerging  growth  company,”  we  intend  to  rely  on  certain  of  these
exemptions,  including  without  limitation,  (1)  providing  an  auditor’s  attestation  report  on  our  system  of  internal  controls  over  financial
reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (2) complying with any requirement that may be adopted by the Public
Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional
information  about  the  audit  and  the  consolidated  financial  statements,  known  as  the  auditor  discussion  and  analysis.  We  may  be  able  to
remain an “emerging growth company” until the earliest of (a) the last day of the fiscal year in which we have total annual gross revenues
of $1 billion or more, (b) the last day of our fiscal year following the fifth anniversary of the date of our IPO, (c) the date on which we have
issued more than $1 billion in non-convertible debt during the previous three years or (d) the date on which we are deemed to be a large
accelerated filer under the rules of the SEC. Additionally, we are also currently a “smaller reporting company” as defined in the Securities
Exchange Act  of  1934,  and  in  the  event  that  we  are  still  considered  a  smaller  reporting  company  at  such  time  as  we  cease  being  an
emerging growth company, we will be exempt from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that independent
registered public accounting firms provide an attestation report on the effectiveness of internal control over financial reporting.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Financial Statements

The consolidated financial statements of Amedica appear at the end of this Annual Report beginning with the index to Financial Statements
on page F-1 (see Part IV, Item 15 “Financial Statements”), and are incorporated herein.

ITEM 9. C H A N G E S IN  AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING  AND  FINANCIAL

DISCLOSURE

On September 20, 2017, we informed BDO USA, LLP (“BDO”) of their dismissal as our independent registered public accounting firm.
The dismissal was authorized by the Audit Committee of our Board of Directors. On the same date, the Audit Committee engaged Tanner
LLC (“Tanner”) as our independent registered public accounting firm for the fiscal year ending December 31, 2017.

The report of BDO on our consolidated financial statements for the fiscal year ended December 31, 2016 did not contain any other adverse
opinion  or  disclaimer  of  opinion  and  were  not  qualified  or  modified  as  to  uncertainty,  audit  scope  or  accounting  principles,  except  that
BDO’s report indicated that there was substantial doubt as to our ability to continue as a going concern.

In connection with the audit of our financial statements for fiscal year ended December 31, 2016, there were no disagreements between us
and  BDO  on  any  matters  of  accounting  principles  or  practices,  financial  statement  disclosure,  or  auditing  scope  or  procedure,  which
disagreements,  if  not  resolved  to  the  satisfaction  of  BDO,  would  have  caused  BDO  to  make  reference  to  the  subject  matter  of  the
disagreements in connection with their audit report on our consolidated financial statements.

In connection with the audit of our financial statements for the year ended December 31, 2016, BDO identified material weaknesses in our
internal control over financial reporting and advised us that the internal controls necessary for us to develop reliable financial statements do
not exist.

68

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  have  not  consulted  with  Tanner  during  our  two  most  recently  completed  fiscal  years  prior  to  their  appointment  as  our  auditor  with
respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that
might be rendered on our consolidated financial statements, or any other matters or reportable events as identified in Items 304(a)(2)(i) and
(ii) of Regulation S-K.

ITEM 9A. CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act
of 1934 (the “Exchange Act”), that are designed to ensure that information required to be disclosed in the reports filed or submitted under
the  Exchange Act,  is  recorded,  processed,  summarized,  and  reported  within  the  time  periods  specified  by  the  Commission’s  rules  and
forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in
our reports filed or submitted under the Exchange Act are properly recorded, processed, summarized and reported within the time periods
required by the Commission’s rules and forms.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer
(principal executive officer and principal financial officer), of the effectiveness of the design and operation of these disclosure controls and
procedures,  as  such  term  is  defined  in  Exchange  Act  Rule  13a-15(e),  as  of  December  31,  2017.  Based  on  this  evaluation,  the  Chief
Executive Officer concluded that our disclosure controls and procedures were not effective as of December 31, 2017, the end of the period
covered by this Annual Report on Form 10-K due to the material weaknesses described below.

(b) Management’s Report on Internal Control over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as defined
in Rules 13a-15(f) and 15d-15(f) under the Exchange Act.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of
its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also,  projections  of  any
evaluation  of  effectiveness  of  internal  control  over  financial  reporting  to  future  periods  are  subject  to  the  risk  that  controls  may  become
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our  internal  control  over  financial  reporting  is  designed  to  provide  reasonable  assurance  of  achieving  its  objectives  as  specified  above.
Management  does  not  expect,  however,  that  our  internal  control  over  financial  reporting  will  prevent  or  detect  all  error  and  fraud. Any
control  system,  no  matter  how  well  designed  and  operated,  is  based  upon  certain  assumptions  and  can  provide  only  reasonable,  not
absolute, assurance that its objectives will be met. Further, no evaluation of controls can provide absolute assurance that misstatements due
to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

Management,  including  our  Chief  Executive  Officer,  has  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of
December  31,  2017.  In  making  our  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting,  management  used  the
criteria set forth in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway
Commission (“COSO”).

As defined in SEC Regulation S-X, a material weakness is a deficiency, or combination of deficiencies, in internal control over financial
reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements
will not be prevented or detected on a timely basis. Based on this assessment, management determined that, as of December 31, 2017, the
Company’s internal control over financial reporting was not effective due to the material weaknesses described below.

The design and operating effectiveness of our controls were inadequate to ensure that complex accounting matters are properly accounted
for  and  reviewed  in  a  timely  manner.  As  a  result,  we  failed  to  accurately  record  a  complex  warrant  transaction  which  caused  the
restatements of our first, second and third quarter 2017 reports on Form 10Q and our 2016 Annual Report on Form 10-K. In addition, we
failed  to  properly  evaluate  and  test  certain  long-lived  assets  for  impairment,  which  ultimately  resulted  in  recognition  of  an  impairment
charge. These errors are a result of the following control deficiencies:

69

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Control Environment and Risk Assessment – The Company did not have an effective control environment with the structure necessary
for effective internal controls over financial reporting. Further, the Company did not have an effective risk assessment to identify and assess
risks  associated  with  changes  to  the  Company’s  structure  and  the  impact  on  internal  controls.  The  Company  did  not  have  appropriately
qualified  personnel  to  meet  the  Company’s  control  objectives.  The  Company  does  not  have  personnel  with  an  appropriate  level  of  US
GAAP knowledge and experience to properly review and evaluate the work performed by other Company personnel and experts related to
complex accounting matters.

Control Activities  –  The  Company  did  not  have  control  activities  that  were  designed  and  operating  effectively  including  management
review controls, controls related to monitoring and assessing the work of consultants, and controls to verify the completeness and adequacy
of  information.  Specifically,  the  Company  did  not  have  procedures  for  competent  personnel  to  review  work  performed  by  experts  in
relation to complex debt and equity transactions and impairment valuations.

Monitoring  Activities  –  The  Company  did  not  maintain  effective  monitoring  controls  related  to  the  financial  reporting  process.  The
Company did not effectively monitor the changes in internal control related to changes in the roles and responsibilities associated with the
changes in personnel and organizational structure. The failure to properly monitor impacted the timing, accuracy, and completion of the
work related to significant accounting matters.

Our Chief Executive Officer continues with a review of our controls relating to complex accounting matters. Although our analysis is not
complete, we have added additional resources with expertise in accounting for complex accounting  matters  including  timely  review  and
evaluation of assets for potential impairment. We are also considering redesigning controls to add additional layers of review and approval
whenever  entering  into  or  subsequently  converting,  exercising,  amending,  repricing,  exiting  or  otherwise  experiencing  changes  in  or  to
complex financial instruments.

Notwithstanding the identified material weaknesses, the Company believes the consolidated financial statements included in this Annual
Report on Form 10-K fairly represent in all material respects our financial condition, results of operations and cash flows at and for the
periods presented in accordance with accounting principles generally accepted in the United States of America.

(d) Changes in Internal Control Over Financial Reporting

Other than described above in the Item 9A. Controls and Procedures, there were no changes in our internal control over financial reporting
that  occurred  during  the  fourth  quarter  of  2017  that  have  materially  affected,  or  are  reasonably  likely  to  materially  affect,  our  internal
control over financial reporting.

Our Board is divided into three classes (Class I, Class II and Class III) with staggered three-year terms. Directors in each class are elected
to  serve  for  three-year  staggered  terms  that  expire  in  successive  years.  Officers  serve  at  the  discretion  of  our  Board.  The  following  is
information on the business experience of each director now serving and a discussion of the qualifications, attributes and skills that led to
the Board of Directors’ conclusion that each one is qualified to serve as a director.

David W. Truetzel  has served on our Board of Directors since our acquisition of US Spine, Inc. in September 2010. Mr. Truetzel has been
the general partner of Augury Capital Partners, a private equity fund that invests in life sciences and information technology companies,

Administration  from  Saint  Louis  University  and  an  M.B.A.  from  The  Wharton  School.  We  believe  that  Mr.  Truetzel’s  financial  and
managerial expertise qualify him to serve on our Board of Directors.

Eric  A.  Stookey  has  served  on  our  Board  of  Directors  since  October  2014.  Mr.  Stookey  has  served  as  Chief  Operating  Officer  of

Mr.  Stookey  earned  his  M.B.A.  from  Christian  Brothers  University  and  his  B.S.  in  Business  from  the  Indiana  University  School  of
Business. We believe that Mr. Stookey’s industry and executive leadership experience qualifies him to serve on our Board of Directors.

B. Sonny Bal, M.D. has served on our Board of Directors since February 2012, as Chairman of our Board of Directors since August 2014
and  as  our  President  and  Chief  Executive  Officer  since  October  2014.  Dr.  Bal  was  a  tenured  Professor  in  Orthopaedic  Surgery  at  the

and Jeffrey S. White, are non-employee directors, and the Board has determined that these persons (who constitute a majority of the Board)
are  “independent  directors”  under  the  criteria  set  forth  in  Rule  5605(a)(2)  of  the  Nasdaq  Listing  Rules.  The  Board  met  twenty-one  (21)
times during the year ended December 31, 2017. All directors attended 86% of the meetings of the Board held during 2017.

In accordance with our restated Certificate of Incorporation, our Board of Directors is divided into three classes with staggered three-year
terms. At each annual meeting of stockholders, the successors to the directors whose terms then expire will be elected to serve until the
third annual meeting following such election. Our directors are divided among the three classes as follows:

● The Class I directors terms will expire at the annual meeting of stockholders to be held in 2018. There are currently no Class I

directors.

● The Class  II  directors  are  David  W.  Truetzel  and  Eric  A.  Stookey,  and  their  terms  will  expire  at  the  annual  meeting  of

stockholders to be held in 2019.

● The Class III directors are B. Sonny Bal, M.D. and Jeffrey S. White, and their terms were initially scheduled to expire at the
annual meeting of stockholders which was to be held in 2017. However, because there was no annual meeting of stockholders
held in 2017 their terms are now set to expire at the annual meeting of stockholders to be held in 2018.

Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as
nearly as possible, each class will consist of one-third of the directors.

Corporate Governance and Nominating Committee

The  Corporate  Governance  and  Nominating  Committee  is  currently  comprised  of  the  following  members:  Eric A.  Stookey  (Chairman),
David W. Truetzel and Jeffrey S White. Among other items, the Corporate Governance and Nominating Committee is tasked by the Board
to: (1) identify individuals qualified to serve as members of the Board and, where appropriate, recommend individuals to be nominated by
the Board for election by the stockholders or to be appointed by the Board to fill vacancies consistent with the criteria  approved  by  the
Board; (2) develop and periodically evaluate and recommend changes to Amedica’s Corporate Governance Guidelines and Code of Ethics,
and to review the Company’s policies and programs that relate to matters of corporate responsibility, including public issues of significance
to the Company and its stakeholders; and (3) oversee an annual evaluation of the performance of the Board. The Board has determined that
each  of  the  members  of  the  Corporate  Governance  and  Nominating  Committee  is  “independent”  under  the  standard  set  forth  in  Rule
5605(a)(2)  of  the  Nasdaq  Listing  Rules.  The  Corporate  Governance  and  Nominating  Committee  did  not  meet  in  2017.  The  Corporate
Governance  and  Nominating  Committee  operates  under  a  written  charter  adopted  by  the  Board  of  Directors,  which  sets  forth  the
responsibilities and powers delegated by the Board to the Corporate Governance and Nominating Committee.

Board Nominations

The  Nominating  and  Governance  Committee  has  adopted  a  policy  and  procedures  for  shareholders  to  recommend  nominees  to  the
Company’s  Board.  The  Committee  will  only  consider  qualified  proposed  nominees  that  meet  the  qualification  standards  set  forth  on
Appendix  A  to  the  Committee’s  charter  available  on  the  Company’s  website  at  www.amedica.com.  Pursuant  to  the  policy,  only
shareholders  who  meet  minimum  percentage  ownership  requirements  as  established  by  the  Board  may  make  recommendations  for
consideration  by  the  Committee. At  this  time,  the  Board  has  set  a  minimum  percentage  ownership  of  5%  of  the  Company’s  issued  and
outstanding  shares  of  common  stock  for  a  period  of  at  least  one  year.  To  make  recommendations,  s  shareholder  must  submit  the
recommendation in writing by mail, courier or personal delivery to: Corporate Secretary, Amedica  Corporation,  1885  West  2100  South,
Salt  Lake  City,  UT  84119.  For  each  annual  meeting  the  Committee  will  consider  only  one  proposed  nominee  from  each  shareholder  or
shareholder group (within the meaning of Regulation 13D under the Exchange Act).

The recommendation must set forth (1) the name, address, including telephone number, of the recommending shareholder or shareholder
group; (2) the number of the Company’s shares of common stock held by such shareholder and proof of ownership if the shareholder is not
a holder of record; and (3) a statement that the shareholder has a good faith intention of holding the shares through the record date of the
Company’s next annual meeting. For shareholder groups this information must be submitted for each shareholder in the group.

The  recommendation  must  set  forth  in  relation  to  the  proposed  nominee  being  recommended  by  the  shareholder:  (1)  the  information
required by Items 401, 403 and 404 of Regulation S-K under the Exchange Act, (2) any material relationships or agreements between the
proposed nominee and the recommending shareholder or the Company’s competitors, customers, labor unions or other persons with special
interests in the Company; (3) a statement regarding the qualifications of the proposed nominee to serve on the Board; (4) a statement that
the  proposed  nominee  can  fairly  represent  the  interests  of  all  shareholders  of  the  Company;  and  (5)  a  signed  consent  by  the  proposed
nominee to being interviewed by the Nominating and Governance Committee.

Recommendations must be made not later than 120 calendar days prior to the first anniversary of the date of the proxy statement for the
prior annual meeting of shareholders. In the event that the date of the annual meeting of shareholders for the current year is more than 30
days following the first anniversary date of the annual meeting of shareholders for the prior year, the submission of a recommendation will
be considered timely if it is submitted not earlier than the close of business on the 120 days prior to such annual meeting and not later than
the  close  of  business  on  the  later  of  90  days  prior  to  such  annual  meeting  or  the  close  of  business  10  days  following  the  day  on  which
public announcement of the date of such meeting is first made by the Company.

Audit Committee

We  have  a  standing  Audit  Committee  and  audit  committee  charter,  which  complies  with  Rule  10A-3  of  the  Exchange  Act,  and  the
requirements of the Nasdaq Listing Rules. Our Audit Committee was established in accordance with Section 3(a)(58)(A) of the Exchange
Act. The Audit Committee is currently comprised of the following members: David W. Truetzel (Chairman), Eric A. Stookey and Jeffrey S
White.  The Audit  Committee  provides  oversight  for  financial  reporting  matters,  internal  controls,  and  compliance  with  the  Company’s
financial policies, and meets with its auditors when appropriate. The Audit Committee met three (3) times in 2017, and all director members
of  the  committee  attended  100%  of  the  meetings.  The  Board  has  determined  that  David  W.  Truetzel  is  an  “audit  committee  financial
expert” within the meaning of Item 407(d)(5) of Regulation S-K. Further, the Board has determined that each of David W. Truetzel, Jeffrey
S. White and Eric A. Stookey are “independent” under the standard set forth in Rule 5605(a)(2) of the Nasdaq Listing Rules. The Audit
Committee operates under a written charter adopted by the Board of Directors, which sets forth the responsibilities and powers delegated by
the Board to the Audit Committee.

Compensation Committee

The Compensation Committee of the Board is comprised of the following members: Jeffrey S. White, (Chairman), David W. Truetzel and
Eric A. Stookey. The Board has determined that each of David W. Truetzel, Jeffrey S. White and Eric A. Stookey are “independent” under
the  standard  set  forth  in  Rule  5605(a)(2)  of  the  Nasdaq  Listing  Rules.  The  Compensation  Committee  recommends  to  the  Board  for
determination compensation of our executive officers, including the chief executive officer, and addresses  salary  and  benefit  matters  for
other key personnel and employees of the Company. The Compensation Committee did not meet in 2017, and all director members of the
committee attended the meetings. The Compensation Committee operates under a written charter adopted by the Board of Directors, which
sets forth the responsibilities and powers delegated by the Board to the Compensation Committee.

Code of Business Conduct

The Board has adopted a Code of Business Conduct that applies to all of our employees, officers and directors, including those officers
responsible  for  financial  reporting.  The  code  of  business  conduct  is  available  on  our  website  at  http://investors.amedica.com/corporate-
governance.cfm. We intend to disclose any amendments to the code or any waivers of its requirements on our website.

The  Bylaws  of  the  Company  provide  that  no  contract  or  transaction  between Amedica  and  one  or  more  of  its  directors  or  officers,  or
between Amedica and any other corporation, firm, association, or other organization in which one or more of its directors or officers are
financially interested, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in
the  meeting  of  the  Board  of  Directors  or  committee  that  authorizes  or  approves  the  contract  or  transaction,  or  because  their  votes  are
counted for such purpose, provided that:

● the material facts as to his, her, or their relationship or interest as to the contract or transaction are disclosed or are known to the
Board of Directors or the committee and noted in the minutes, and the Board of Directors or committee authorizes the contract
or  transaction  in  good  faith  by  the  affirmative  vote  of  a  majority  of  disinterested  directors,  even  though  the  disinterested
directors are less than a quorum;

● the material facts as to his, her, or their relationship or interest as to the contract or transaction are disclosed or are known to the
stockholders  entitled  to  vote  thereon  and  the  contract  or  transaction  is  specifically  approved  in  good  faith  by  vote of  the
stockholders; or

● the contract or transaction is fair as to Amedica as of the time it is authorized, approved or ratified by the Board of Directors, a

committee thereof, or the stockholders.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our officers, directors, and persons who beneficially own more
than  10%  of  our  common  stock  (“10%  Stockholders”),  to  file  reports  of  ownership  and  changes  in  ownership  with  the  Securities  and
Exchange Commission (“SEC”). Such officers, directors and 10% Stockholders are also required by SEC rules to furnish us with copies of
all Section 16(a) forms that they file.

Based  solely  on  our  review  of  the  copies  of  such  forms  received  by  us,  or  written  representations  from  certain  reporting  persons,  the
Company believes that during fiscal year ended December 31, 2017, the filing requirements applicable to its officers, directors and greater
than 10% percent beneficial owners were complied with.

401(k) Plan

We  offer  our  executive  officers,  including  our  named  executive  officers,  retirement  benefits,  including  participation  in  our  tax-qualified
profit sharing plan that includes a “cash-or-deferred” (or 401(k)) feature in the same manner as other employees. The plan is intended to
satisfy the requirements of Section 401 of the Internal Revenue Code. Our employees may elect to reduce their current compensation by up
to  the  statutorily  prescribed  annual  limit  and  have  a  like  amount  contributed  to  the  plan.  In  addition,  we  may  make  discretionary  and/or
matching  contributions  to  the  plan  in  amounts  determined  annually  by  our  Board.  We  currently  elect  to  match  the  contributions  of  our
employees  who  participate  in  our  401(k)  plan  as  follows:  a  match  of  100%  on  the  first  3%  of  compensation  contributed  by  a  plan
participant and a match of 50% on amounts above 3%, up to 5%, of compensation contributed by a plan participant.

Potential Payments upon Termination or Change in Control

We had entered into certain agreements and maintained certain plans that may have required us to make certain payments and/or provide
certain  benefits  to  the  executive  officers  named  in  the  Summary  Compensation  Table  in  the  event  of  a  termination  of  employment  or
change in control.

Pursuant to severance agreements that we have entered into with each of our named executive officers, upon the consummation of a change
in control, all outstanding options, restricted stock and other such rights held by the executives will fully vest. Additionally, if a change in
control occurs and at any time during the one-year period following the change in control (i) we or our successor terminate the executive’s
employment other than for cause (but not including termination due to the executive’s death or disability) or (ii) the executive terminates
his employment for good reason, then such executive has the right to receive payment consisting of a lump sum payment equal to two times
his  highest  annual  salary  with  us  during  the  preceding  three-year  period,  including  the  year  of  such  termination  and  including  bonus
payments (measured on a fiscal year basis), but not including any reimbursements and amounts attributable to stock options and other non-
cash compensation. “Change in control” is defined in the severance agreements as occurring upon: (i) any “person” (as such term is used in
Sections  13(d)  and  14(d)  of  the  Exchange Act)  becoming  the  “beneficial  owner”  (as  defined  in  Rule  13d-3  under  the  Exchange Act),
directly or indirectly, of securities representing 50% or more of the total voting power represented by our then outstanding voting securities
(excluding  securities  held  by  us  or  our  affiliates  or  any  of  our  employee  benefit  plans)  pursuant  to  a  transaction  or  a  series  of  related
transactions which our Board did not approve; (ii) a merger or consolidation of our company, other than a merger or consolidation which
would result in our voting securities outstanding immediately prior thereto continuing to represent at least 50% of the total voting securities
or such surviving entity or parent of such corporation outstanding immediately after such merger or consolidation; or (iii) the approval by
our stockholders of an agreement for the sale or disposition of all or substantially all of our assets. As defined in the severance agreements,
“cause” means: (i) the executive’s commission of a felony (other than through vicarious liability or through a motor vehicle offense); (ii)
the  executive’s  material  disloyalty  or  dishonesty  to  us;  (iii)  the  commission  by  the  executive  of  an  act  of  fraud,  embezzlement  or
misappropriation of funds; (iv) a material breach by the executive of any material provision of any agreement to which the executive and we
are  party,  which  breach  is  not  cured  within  30  days  after  our  delivery  to  the  executive  of  written  notice  of  such  breach;  or  (v)  the
executive’s refusal to carry out a lawful written directive from our Board. “Good reason” as defined in the severance agreements means,
without the executive’s consent: (i) a change in the principal location at which the executive performs his duties to a new work location
that is at least 50 miles from the prior location; or (ii) a material change in the executive’s compensation, authority, functions, duties or
responsibilities,  which  would  cause  his  position  with  us  to  become  of  less  responsibility,  importance  or  scope  than  his  prior  position,
provided,  however,  that  such  material  change  is  not  in  connection  with  the  termination  of  the  executive’s  employment  with  us  for  any
reason.

77

 
 
 
 
 
 
 
 
 
In the event that an officer entitled to receive or receives payment or benefit under the severance agreements described above, or under any
other plan, agreement or arrangement with us, or any person whose action results in a change in control or any other person affiliated with
us and it is determined that the total amount of payments will be subject to excise tax under Section 4999 of the Internal Revenue Code, or
any similar successor provisions, we will be obligated to pay such officer a “gross up” payment to cover all taxes, including any excise tax
and any interest or penalties imposed with respect to such taxes due to such payment.

Code of Business Conduct Violations

It is our policy under our Code of Business Conduct to take appropriate action against any executive officer whose actions are found to
violate  the  Code  or  any  other  policy  of Amedica.  Disciplinary  actions  may  include  immediate  termination  of  employment  and,  where
Amedica  has  suffered  a  loss,  pursuing  its  remedies  against  the  executive  officer  responsible.  Amedica  will  cooperate  fully  with  the
appropriate authorities where laws have been violated.

Company’s  consolidated  financial  statements  included  in  this Annual  Report  on  Form  10-K  for  the  fiscal  year  ended  December  31,
2017.

During 2016, our Board approved the following compensation schedule for non-employee directors (paid on a quarterly basis):

● Annual Retainer of $40,000 paid in four equal installments of $10,000 each at the beginning of each calendar quarter;

● $1,000 for each board and committee meeting attended in person;

● $500 for each board and committee meeting attended via telephone or other remote medium; and

● Reimbursement of reasonable expenses as supported by documentation and receipts.

Starting in 2015, a new Board appointee receives an award of 40,000 stock options upon appointment. Further, each member of the Board
will also be awarded an option grant for 15,000 stock options on an annual basis.

The chair of the Audit Committee is paid an annual retainer of $120,000 payable in monthly increments of $10,000 each.

ITEM 12. SECURITY OWNERSHIP  OF  CERTAIN  BENEFICIAL  OWNERS  AND  MANAGEMENT  AND  RELATED

STOCKHOLDER MATTERS

The following table sets forth certain information regarding the beneficial ownership of our common stock as of March 27, 2018 by:

●

●

●

●

each of our current directors;

each of our executive officers; and

all of our directors and executive officers as a group;

each stockholder known by us to own beneficially more than 5% of our Common Stock.

Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to the
securities.  Shares  of  common  stock  that  may  be  acquired  by  an  individual  or  group  within  60  days  of  March  27,  2018,  pursuant  to  the
exercise or vesting of options or warrants or conversion of convertible promissory notes, are deemed to be outstanding for the purpose of
computing the percentage ownership of such individual or group, but are not deemed to be outstanding for the purpose of computing the
percentage ownership of any other person shown in the table. Percentage of shares beneficially owned is based on 4,276,844 shares issued
and outstanding on March 27, 2018.

Except as indicated in footnotes to this table, we believe that the stockholders named in this table have sole voting and investment power
with  respect  to  all  shares  of  common  stock  shown  to  be  beneficially  owned  by  them,  based  on  information  provided  to  us  by  such
stockholders.  The  address  for  each  director  and  executive  officer  listed  is:  c/o Amedica  Corporation,  1885  West  2100  South,  Salt  Lake

2012 Equity Incentive Plan

The 2012 Plan is intended to encourage ownership of common stock by our employees and directors and certain of our consultants in order
to attract and retain such people, to induce them to work for the benefit of us and to provide additional incentive for them to promote our
success. The number of shares of our common stock reserved for issuance under the 2012 Plan is 95,202, which number is automatically
increased  on  January  1  of  each  of  year  by  the  lesser  of  (i)  18,031  shares  of  our  common  stock  on  such  date,  (ii)  5%  of  the  number  of
outstanding shares of our common stock on such date, and (iii) such other amount determined by the board through the termination of the
2012 Plan.

Types of Awards.  The 2012 Plan provides for the granting of incentive stock options, NQSOs, stock grants and other stock-based awards,
including RSUs.

●  Incentive  and  Nonqualified  Stock  Options.  The  plan  administrator  determines  the  exercise  price  of  each  stock  option.  The
exercise price of an NQSO may not be less than the fair market value of our common stock on the date of grant. The exercise price
of an incentive stock option may not be less than the fair market value of our common stock on the date of grant if the recipient
holds 10% or less of the combined voting power of our securities, or 110% of the fair market value of a share of our common stock
on the date of grant otherwise.

● Stock Grants. The plan administrator may grant or sell stock, including restricted stock, to any participant, which purchase price,
if  any,  may  not  be  less  than  the  par  value  of  shares  of  our  common  stock.  The  stock  grant  will  be  subject  to  the  conditions  and
restrictions determined by the administrator. The recipient of a stock grant shall have the rights of a stockholder with respect to the
shares of stock issued to the holder under the 2012 Plan.

● Stock-Based Awards. The administrator of the 2012 Plan may grant other stock-based awards, including stock appreciation rights,
phantom stock awards and RSUs, with terms approved by the administrator, including restrictions related to the awards. The holder
of  a  stock-based  award  shall  not  have  the  rights  of  a  stockholder  until  shares  of  our  common  stock  are  issued  pursuant  to  such
award.

Plan Administration. Our Board is the administrator of the 2012 Plan, except to the extent it delegates its authority to a committee, in which
case the committee shall be the administrator. Our Board has delegated this authority to our compensation committee. The administrator
has the authority to determine the terms of awards, including exercise and purchase price, the number of shares subject to awards, the value
of our common stock, the vesting schedule applicable to awards, the form of consideration, if any, payable upon exercise or settlement of an
award and the terms of award agreements for use under the 2012 Plan.

Eligibility. Our Board will determine the participants in the 2012 Plan from among our employees, directors and consultants. A grant may
be approved in advance with the effectiveness of the grant contingent and effective upon such person’s commencement of service within a
specified period.

Termination of Service. Unless otherwise provided by our Board or in an award agreement, upon a termination of a participant’s service, all
unvested options then held by the participant will terminate and all other unvested awards will be forfeited.

Transferability.  Awards  under  the  2012  Plan  may  not  be  transferred  except  by  will  or  by  the  laws  of  descent  and  distribution,  unless
otherwise provided by our Board in its discretion and set forth in the applicable agreement, provided that no award may be transferred for
value.

Adjustment. In the event of a stock dividend, stock split, recapitalization or reorganization or other change in change in capital structure, our
Board will make appropriate adjustments to the number and kind of shares of stock or securities subject to awards.

Corporate Transaction. If we are acquired, our Board of Directors (or Compensation Committee) will: (i) arrange for the surviving entity or
acquiring entity (or the surviving or acquiring entity’s parent company) to assume or continue the award or to substitute a similar award for
the award; (ii) cancel or arrange for cancellation of the award, to the extent not vested or not exercised prior to the effective time of the
transaction, in exchange for such cash consideration, if any, as our Board of Directors in its sole discretion, may consider appropriate; or
(iii) make a payment, in  such  form  as  may  be  determined  by  our  Board  of  Directors  equal  to  the  excess,  if  any,  of  (A)  the  value  of  the
property the holder would have received upon the exercise of the award immediately prior to the effective time of the transaction, over (B)
any exercise price payable by such holder in connection with such exercise. In addition, in connection with such transaction, our Board of
Directors may accelerate the vesting, in whole or in part, of the award (and, if applicable, the time at which the award may be exercised) to
a date prior to the effective time of such transaction and may arrange for the lapse, in whole or in part, of any reacquisition or repurchase
rights held by us with respect to an award.

Amendment and Termination. The 2012 Plan will terminate on September 6, 2022 or at an earlier date by vote of the stockholders or our
Board; provided, however, that any such earlier termination shall not affect any awards granted under the 2012 Plan prior to the date of
such termination. The 2012 Plan may be amended by our Board, except that our Board may not alter the terms of the 2012 Plan if it would
adversely  affect  a  participant’s  rights  under  an  outstanding  stock  right  without  the  participant’s  consent.  Stockholder  approval  will  be
required  for  any  amendment  to  the  2012  Plan  to  the  extent  such  approval  is  required  by  law,  include  the  Internal  Revenue  Code  or
applicable stock exchange requirements.

Amendment  of  Outstanding  Awards. The  administrator  may  amend  any  term  or  condition  of  any  outstanding  award  including,  without
limitation, to reduce or increase the exercise price or purchase price, accelerate the vesting schedule or extend the expiration date, provided
that no such amendment shall impair the rights of a participant without such participant’s consent.

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

Transactions with Related Persons

Except as set forth below, we have not entered into any transactions since January 1, 2015 to which we have been a party, in which the
amount involved in the transaction exceeded the lesser of $120,000 or one percent of the average of our total assets at year-end for the last
two completed fiscal years, and in which any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5%
of our common stock, on an as converted basis, or any member of the immediate family of any of the foregoing persons had or will have a
direct or indirect material interest, other than equity and other compensation, termination, change in control and other arrangements, which
are described under “Executive and Director Compensation.”

81

 
 
 
 
 
 
 
 
 
 
 
 
 
 
On July 28, 2017, we closed on a $2.5 million term loan with North Stadium Investments, LLC, or North Stadium, a company owned and
controlled  by  our  Chief  Executive  Officer  and  Chairman  of  the  Board,  Dr.  Sonny  Bal.  In  connection  with  the  loan,  we  issued  to  North
Stadium, a Secured Promissory Note in the amount of $2.5 million (the “Note”). The Note bears interest at the rate of  10%  per  annum,
requires us to make monthly interest only payments for a period of 12 months, and principal and any unpaid accrued interest are due and
payable 12 months from the effective date of the Note, July 28, 2017. The Note is secured by substantially all of the assets of the Company
pursuant to a security agreement between the Company and North Stadium. In connection with the Loan and as additional consideration for
the Loan, the Company issued to North Stadium a warrant to acquire up to 55,000 common shares with a purchase price set at $5.04 per
share and a 5-year term.

Indemnification Agreements .  We  have  entered  into  indemnification  agreements  with  each  of  our  executive  officers  and  directors  that
require us to indemnify such persons against any and all expenses, including judgments, fines or penalties, attorney’s fees, witness fees or
other professional fees and related disbursements and other out-of-pocket costs incurred, in connection  with  any  action,  suit,  arbitration,
alternative  dispute  resolution  mechanism,  investigation,  inquiry  or  administrative  hearing,  whether  threatened,  pending  or  completed,  to
which any such person may be made a party by reason of the fact that such person is or was a director, officer, employee or agent of our
company, provided that such director or officer acted in good faith and in a manner that the director or officer reasonably believed to be in,
or not opposed to, our best interests. The indemnification agreements also set forth procedures that will apply in the event of a claim for
indemnification  thereunder.  We  believe  that  these  provisions  and  agreements  are  necessary  to  attract  and  retain  qualified  persons  as
directors and officers.

Policy for Review of Related Party Transactions

We have a policy for the review of transactions with related persons as set forth in our Audit Committee Charter and internal practices. The
policy requires review, approval or ratification of all transactions in which we are a participant and in which any of our directors, executive
officers,  shareholders  holding  more  than  5%  of  our  outstanding  common  stock,  an  immediate  family  member  of  any  of  the  foregoing
persons or any other person who the Board determines may be considered to be a related person has a direct or indirect material interest and
which  meet  the  threshold  requirements  set  forth  in  Item  404  of  Regulation  S-K  under  the  Exchange Act  (typically  $120,000  or  more  in
value). All related party transactions must be reported for review by the Audit Committee pursuant to the Audit Committee’s charter.

In  reviewing  and  approving  such  transactions,  the Audit  Committee  shall  obtain,  or  shall  direct  management  to  obtain  on  its  behalf,  all
information that the Audit Committee believes to be relevant and important to a review of the transaction prior to its approval. Following
receipt of the necessary information, a discussion shall be held of the relevant factors if deemed to be necessary by the Audit Committee
prior to approval. No related party transaction shall be entered into prior to the completion of these procedures.

Following its review, the Audit Committee determines whether these transactions are in, or not inconsistent with, the best interests of the
Company and its stockholders, taking into consideration whether they are on terms no less favorable to the Company than those available
with other parties and the related person’s interest in the transaction.

Our policy for review of transactions with related persons was followed in all of the transactions set forth above and all such transactions
were reviewed and approved in accordance with our policy for review of transactions with related persons.

Information regarding the independence of directors is disclosed above under Item 10 under the heading “The Board and Committees” and

Policy for Approval of Audit and Permitted Non-Audit Services

The Audit Committee charter provides that the Audit Committee will pre-approve audit services and non-audit services to be provided by
our independent auditors before the accountant is engaged to render these services. The Audit Committee may consult with management in
the decision-making process, but may not delegate this authority to management. The Audit Committee may delegate its authority to pre-
approve  services  to  one  or  more  committee  members,  provided  that  the  designees  present  the  pre-approvals  to  the  full  committee  at  the
next committee meeting.

Board of Directors and Stockholders of
Amedica Corporation
Salt Lake City, Utah

Opinion on the Consolidated Financial Statements 

We have audited the accompanying consolidated balance sheet of Amedica Corporation and subsidiaries (the “Company”) as of December
31,  2017  and  the  related  consolidated  statements  of  operations,  stockholders’  equity,  and  cash  flows  for  the  year  then  ended,  and  the
related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Company as of December 313, 2017, and the results of its operations and its cash flows
for the year then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion 

These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the
Company’s  financial  statements  based  on  our  audit.  We  are  a  public  accounting  firm  registered  with  the  Public  Company Accounting
Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S.
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our
audits  we  are  required  to  obtain  an  understanding  of  internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an
opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts
and  disclosures  in  the  financial  statements.  Our  audit  also  included  evaluating  the  accounting  principles  used  and  significant  estimates
made  by  management,  as  well  as  evaluating  the  overall  presentation  of  the  consolidated  financial  statements.  We  believe  that  our  audit
provides a reasonable basis for our opinion.

Other Matter

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As
discussed in Note 1 to the consolidated financial statements, the Company has recurring losses from operations and negative operating cash
flows  and  needs  to  obtain  additional  financing  to  be  compliant  with  debt  covenants  and  to  finance  its  operations.  These  issues  raise
substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note
1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Amedica Corporation
Salt Lake City, Utah

We have audited the accompanying consolidated balance sheet of Amedica Corporation (the “Company”) as of December 31, 2016 and the
related consolidated statements of operations, stockholders’ equity, and cash flows for the year then ended. These financial statements are
the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our
audit.

We  conducted  our  audit  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. The Company has determined that it is not required to have, nor were we engaged to perform, an audit of its internal
control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit
procedures  that  are  appropriate  in  the  circumstances,  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the
Company’s  internal  control  over  financial  reporting. Accordingly,  we  express  no  such  opinion. An  audit  includes  examining,  on  a  test
basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant
estimates  made  by  management,  as  well  as  evaluating  the  overall  financial  statement  presentation.  We  believe  that  our  audit  provides  a
reasonable basis for our opinion.

In  our  opinion,  the  consolidated  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  financial  position  of
Amedica Corporation at December 31, 2016, and the results of its operations and its cash flows for the year then ended, in conformity with
accounting principles generally accepted in the United States of America.

As discussed in Note 13, the accompanying consolidated financial statements have been restated to correct misstatements.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As
discussed in Note 1 to the consolidated financial statements, the Company has recurring losses from operations and negative operating cash
flows and needs to obtain additional financing to be compliant with debt covenants through 2016. These issues raise substantial doubt about
its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated
financial statements do not include any adjustments that might result from the outcome of this uncertainty.

1. Organization and Summary of Significant Accounting Policies

Amedica  Corporation  (“Amedica”  or  “the  Company”)  was  incorporated  in  the  state  of  Delaware  on  December  10,  1996. Amedica  is  a
commercial-stage  biomaterial  company  focused  on  using  its  silicon  nitride  technology  platform  to  develop,  manufacture,  and
commercialize  a  broad  range  of  medical  devices.  The  Company  believes  it  is  the  first  and  only  manufacturer  to  use  silicon  nitride  in
medical  applications.  The  Company  acquired  US  Spine,  Inc.  (“US  Spine”),  a  Delaware  spinal  products  corporation  with  operations  in
Florida, on September 20, 2010. The Company’s products are primarily sold in the U.S.

Basis of Presentation and Principles of Consolidation

These consolidated financial statements have been prepared by management in accordance with accounting principles generally accepted in
the  United  States  (“U.S.  GAAP”),  and  include  all  assets  and  liabilities  of  the  Company  and  its  wholly-owned  subsidiary,  US  Spine. All
material intercompany transactions and balances have been eliminated in consolidation.

Liquidity and Capital Resources

The  consolidated  financial  statements  have  been  prepared  assuming  the  Company  will  continue  to  operate  as  a  going  concern,  which
contemplates the realization of assets and settlement of liabilities in the normal course of business, and does not include any adjustments to
reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may
result from uncertainty related to its ability to continue as a going concern within one year from the date of issuance of these consolidated
financial statements.

For the years ended December 31, 2017 and 2016, the Company incurred a net loss of $9.3 million and $14.8 million, respectively, and
used  cash  in  operations  of  $4.7  million  and  $7.2  million,  respectively.  The  Company  had  an  accumulated  deficit  of  $220.6  million  and
$211.3 million as of December 31, 2017 and 2016, respectively. To date, the Company’s operations have been principally financed from
proceeds  from  the  issuance  of  preferred  and  common  stock,  convertible  debt  and  bank  debt  and,  to  a  lesser  extent,  cash  generated  from
product  sales.  It  is  anticipated  that  the  Company  will  continue  to  generate  operating  losses  and  use  cash  in  operations.  The  Company’s
continuation as a going concern is dependent upon its ability to increase sales, implement cost saving measures, maintain compliance with
debt  covenants  and/or  raise  additional  funds  through  the  capital  markets.  Whether  and  when  the  Company  can  attain  profitability  and
positive cash flows from operations or obtain additional financing is uncertain.

In  2016,  the  Company  implemented  certain  cost  saving  measures,  including  workforce  and  office  space  reductions,  and  continued  to
evaluate  additional  cost  savings  alternatives  during  2017.  These  additional  cost  savings  measures  may  include  additional  workforce  and
research  and  development  reductions,  as  well  as  cuts  to  certain  other  operating  expenses.  In  addition  to  these  cost  saving  measures  an
experienced and highly successful leader for the Sales and Marketing team was recruited and hired. This individual has subsequently hired
additional experienced personnel in Sales and Market Development. The Company is actively generating additional scientific and clinical
data to have it published in leading industry publications. The unique features of our silicon nitride material are not well known, and such
the publication of such data would help sales efforts as the Company approaches new prospects. The Company is also making additional
changes  to  the  sales  strategy,  including  a  focus  on  revenue  growth  of  silicon  nitride  lateral  lumbar  implants  and  the  newly  developed
pedicle screw system (known as Taurus).

On July 28, 2017, the Company entered into a $2.5 million term loan with a related party. The Company has common stock that is publicly
traded and has been able to successfully raise capital when needed since the date of the Company’s initial public offering. Subsequent to
December  31,  2017,  the  Company  was  able  to  raise  equity  funding  through  the  exercise  of  outstanding  warrants  (see  Note  13).  The
Company is engaged in discussions with investment and banking firms to examine financing alternatives, including options for a public
offering of the Company’s preferred or common stock.

Although the Company is seeking to obtain additional equity and/or debt financing, such funding is not assured and may not be available to
the Company on favorable or acceptable terms and may involve significant restrictive covenants. Any additional equity financing is also
not assured and, if available to the Company, will most likely be dilutive to its current stockholders. If the Company is not able to obtain
additional debt or equity financing on a timely basis, the impact on the Company will be material and adverse.

F-8

 
 
 
 
 
 
 
 
 
 
 
 
 
 
These uncertainties create substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not
include any adjustments that might result from the outcome of these uncertainties.

Reverse Stock Split

On  November  10,  2017,  the  Company  effected  a  1  for  12  reverse  stock  split  of  the  Company’s  common  stock.  The  par  value  and  the
authorized shares of the common and convertible preferred stock were not adjusted as a result of the reverse stock split. All common stock
share  and  per-share  amounts  for  all  periods  presented  in  these  consolidated  financial  statements  prior  to  November  10,  2017  have  been
adjusted retroactively to reflect the reverse stock split.

Use of Estimates

The  preparation  of  consolidated  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  estimates  and
assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the
consolidated  financial  statements  and  the  reported  amounts  of  revenue  and  expenses  during  the  period. Actual  results  could  differ  from
those  estimates.  Some  of  the  more  significant  estimates  relate  to  inventory,  stock-based  compensation,  long-lived  and  intangible  assets,
goodwill, and derivative liabilities.

Concentrations of Credit Risk and Significant Customers

Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents,
marketable securities, accounts receivable and restricted cash. The Company limits its exposure to credit loss by placing its cash and cash
equivalents  with  high  credit-quality  financial  institutions  in  bank  deposits,  money  market  funds,  U.S.  government  securities  and  other
investment grade debt securities that have strong credit ratings. The Company has established guidelines relative to diversification of its
cash  and  marketable  securities  and  their  maturities  that  are  intended  to  secure  safety  and  liquidity.  These  guidelines  are  periodically
reviewed  and  modified  to  take  advantage  of  trends  in  yields  and  interest  rates  and  changes  in  the  Company’s  operations  and  financial
position. Although the Company may deposit its cash and cash equivalents with multiple financial institutions, its deposits, at times, may
exceed federally insured limits.

At December 31, 2017, one customer receivable balance was 12% of the Company’s total trade accounts receivable.
One customer accounted for 21% of the Company’s total revenues for the year ended December 31, 2017.
At  December  31,  2016,  one  customer  receivable  balance  was  16%  of  the  Company’s  total  trade  accounts  receivable.  One  customer
accounted for 17% of the Company’s total revenues for the year ended December 31, 2016.

Revenue Recognition

The  Company  derives  its  product  revenue  primarily  from  the  sale  of  spinal  fusion  devices  and  related  products  used  in  the  treatment  of
spine  disorders.  The  Company’s  product  revenue  is  generated  from  sales  to  three  types  of  customers:  (1)  surgeons  and  hospitals;  (2)
stocking distributors; and (3) private label customers. Most of the Company’s products are sold on a consignment basis through a network
of  independent  sales  distributors;  however,  the  Company  also  sells  its  products  to  independent  stocking  distributors  and  private  label
customers.  Product  revenue  is  recognized  when  all  four  of  the  following  criteria  are  met:  (1)  persuasive  evidence  that  an  arrangement
exists;  (2)  delivery  of  the  products  has  occurred;  (3)  the  selling  price  of  the  product  is  fixed  or  determinable;  and  (4)  collectability  is
reasonably assured. The Company generates the majority of its revenue from the sale of inventory that is consigned to independent sales
distributors that facilitate sales of the Company’s products to surgeons and hospitals. For these products, we recognize revenue at the time
we are notified the product has been used or implanted and all other revenue recognition criteria have been met. For all other transactions,
the  Company  recognizes  revenue  when  title  and  risk  of  loss  transfer  to  the  stocking  distributor  or  private  label  customer,  and  all  other
revenue  recognition  criteria  have  been  met.  The  Company  recognizes  revenue  from  sales  to  stocking  distributors  and  private  label
customers at the time the product is shipped. Stocking distributors, who sell the products to their customers, take title to the products and
assume  all  risks  of  ownership  at  time  of  shipment.  The  Company’s  stocking  distributors  are  obligated  to  pay  within  specified  terms
regardless of when, if ever, they sell the products. The Company’s policy is to classify shipping and handling costs billed to customers as
an  offset  to  total  shipping  expense  in  the  consolidated  statements  of  operations,  primarily  within  sales  and  marketing.  In  general,  the
Company’s customers do not have any rights of return or exchange.

Costs of Revenue

The  expenses  that  are  included  in  costs  of  revenue  include  all  direct  product  costs  if  we  obtained  the  product  from  third-party
manufacturers and our in-house manufacturing costs for the products we manufacture. We obtain our non-silicon nitride products, including
our metal and orthobiologic products, from third-party manufacturers, while we currently manufacture the majority of our silicon-nitride
products in-house.

Specific provisions for excess or obsolete inventory are also included in costs of revenue. In addition, we pay royalties attributable to the
sale  of  specific  products  to  some  of  our  surgeon  advisors  that  assisted  us  in  the  design,  regulatory  clearance  or  commercialization  of  a
particular product, and these payments are recorded as costs of revenue.

Cash and Cash Equivalents

The Company considers all cash on deposit, money market accounts and highly-liquid debt instruments purchased with original maturities
of three months or less to be cash and cash equivalents.

Inventories

Inventories are stated at the lower of cost or net realizable value, with cost for manufactured inventory determined under the standard costs,
which  approximate  actual  costs,  determined  on  the  first-in  first-out  (“FIFO”)  method.  Manufactured  inventory  consists  of  raw  material,
direct labor and manufacturing overhead cost components. Inventories purchased from third-party manufacturers are stated at the lower of
cost or market using the first-in, first-out method. The Company reviews the carrying value of inventory on a periodic basis for excess or
obsolete items, and records any write-down as a cost of revenue, as necessary. It is reasonably possible that the Company may be required
to  make  adjustments  to  the  carrying  value  of  inventory  in  future  periods.  Inventory  write-downs  for  excess  or  obsolete  inventory  are
recorded  as  a  cost  of  revenue.  The  Company  holds  consigned  inventory  at  distributor  and  other  customer  locations  where  revenue
recognition criteria have not yet been achieved.

Property and Equipment

Property and equipment, including surgical instruments and leasehold improvements, are stated at cost, less accumulated depreciation and
amortization.  Property  and  equipment  are  depreciated  using  the  straight-line  method  over  the  estimated  useful  lives  of  the  assets,  which
range from three to five years. Leasehold improvements are amortized over the shorter of their estimated useful lives or the related lease
term, generally five years.

Periodically the Company reviews the carrying value of the Company’s property and equipment that are held and used in the Company’s
operations  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  an  asset  may  not  be
recoverable. Recoverability of these assets is determined based upon expected undiscounted future net cash flows from the operations to
which the assets relate, utilizing management’s best estimate, assumptions, and projections at the time. If the carrying value is determined
to be unrecoverable from future operating cash flows, the asset is deemed impaired and an impairment charge would be recognized to the
extent  the  carrying  value  exceeded  the  estimated  fair  value  of  the  asset.  The  Company  estimates  the  fair  value  of  assets  based  on  the
estimated  future  discounted  cash  flows  of  the  asset.  Management  has  evaluated  its  property  and  equipment  and  identified  specific  asset
impairments during the year ended December 31, 2016. No impairment was identified during the year ended December 31, 2017.

Accounts Receivable and Allowance for Doubtful Accounts

The majority of the Company’s accounts receivable is composed of amounts due from hospitals or surgical centers. Accounts receivable
are carried at invoiced amount less an allowance for doubtful accounts. On a regular basis, the Company evaluates accounts receivable and
estimate  an  allowance  for  doubtful  accounts,  as  needed,  based  on  various  factors  such  as  customers’  current  credit  conditions,  length  of
time past due, and the general economy as a whole. Receivables are written off against the allowance when they are deemed uncollectible.

Long Lived Intangible Assets and Goodwill

The Company periodically evaluates the carrying value of definite-lived intangibles when events or changes in circumstances indicate that
the carrying value may not be recoverable. Factors the Company considers important which could trigger an impairment review include,
but are not limited to, significant under-performance relative to historical or projected future operating results, significant changes in the
manner of its use of acquired assets or its overall business strategy, and significant industry or economic trends. The Company amortizes
definite-lived intangible assets on a straight-line basis over their useful lives. The Company recorded no impairment loss for definite-lived
intangible assets during the years ended December 31, 2017 and 2016.

When the Company determines that the carrying value of  a  long-lived  asset  may  not  be  recoverable  based  upon  the  existence  of  one  or
more  of  the  above  indicators,  the  Company  determines  the  recoverability  by  comparing  the  carrying  amount  of  the  asset  to  net  future
undiscounted  cash  flows  that  the  asset  is  expected  to  generate  and  recognizes  an  impairment  charge  equal  to  the  amount  by  which  the
carrying amount exceeds the fair market value of the asset.

If  the  Company’s  revenues  or  other  estimated  operating  results  are  not  achieved  at  or  above  our  forecasted  level,  and  the  Company  is
unable to recover such costs through price increases, the carrying value of certain of the Company’s assets may prove to be unrecoverable
and we may incur impairment charges of definitive-live intangible assets.

In  accordance  with  ASC  350,  Goodwill  and  Other  Intangible  Assets,  goodwill  is  not  amortized  but  is  required  to  be  reviewed  for
impairment  at  least  annually  or  when  events  or  circumstances  indicate  that  carrying  value  may  exceed  fair  value.  The  Company  is
permitted  the  option  to  first  assess  qualitative  factors  to  determine  whether  the  existence  of  events  and  circumstances  indicates  that  it  is
more likely than not that the fair value of any reporting unit is less than its corresponding carrying value. If, after assessing the totality of
events and circumstances, the Company concludes that it is not more likely than not that the fair value of any reporting unit is less than its
corresponding carrying value then the Company is not required to take further action. However, if the Company concludes otherwise, then
it is required to perform a quantitative impairment test, including computing the fair value of the reporting unit and comparing that value to
its carrying value. The Company considers valuation factors and an estimated control premium. If the fair value is less than its carrying
value,  a  second  step  of  the  test  is  required  to  determine  if  recorded  goodwill  is  impaired.  In  the  event  that  goodwill  is  impaired,  an
impairment charge to earnings would become necessary.

The estimated fair value of the reporting unit exceeded the carrying value as of December 31, 2017 and 2016. The declining price of the
Company’s stock is an early indicator that goodwill impairment may be a factor during 2018. The Company will continue to monitor the
Company’s  market  capitalization  and  impairment  indicators.  In  the  event  that  goodwill  is  impaired,  an  impairment  charge  to  earnings
would become necessary.

Derivative Liabilities

Derivative liabilities include the fair value of instruments such as common stock warrants, preferred stock warrants and convertible features
of notes, that are initially recorded at fair value and are required to be re-measured to fair value at each reporting period under provisions of
ASC  480, Distinguishing  Liabilities  from  Equity,  or ASC  815, Derivatives and Hedging.  The  change  in  fair  value  of  the  instruments  is
recognized as a component of other income (expense) in the Company’s consolidated statements of operations until the instruments settle,
expire  or  are  no  longer  classified  as  derivative  liabilities.  The  Company  estimates  the  fair  value  of  these  instruments  using  the  Black-
Scholes-Merton or Monte-Carlo valuation models depending on the complexity of the underlying instrument. The significant assumptions
used in estimating the fair value include the exercise price, volatility of the stock underlying the instrument, risk-free interest rate, estimated
fair value of the stock underlying the instrument and the estimated life of the instrument.

Research and Development

All  research  and  development  costs,  including  those  funded  by  third  parties,  are  expensed  as  incurred.  Research  and  development  costs
consist  of  engineering,  product  development,  test-part  manufacturing,  testing,  developing  and  validating  the  manufacturing  process,  and
regulatory  related  costs.  Research  and  development  expenses  also  include  employee  compensation,  employee  and  nonemployee  stock-
based compensation, supplies and materials, consultant services, and travel and facilities expenses related to research activities.

Advertising Costs

Advertising  costs  are  expensed  as  incurred.  The  primary  component  of  the  Company’s  advertising  expenses  is  advertising  in  trade
periodicals. Advertising costs were less than $0.1 million for each of the years ended December 31, 2017 and 2016.

Income Taxes

The  Company  recognizes  deferred  tax  assets  and  liabilities  for  the  future  tax  consequences  attributable  to  the  differences  between  the
financial  statement  carrying  value  of  existing  assets  and  liabilities  and  their  respective  tax  bases.  Deferred  tax  assets  and  liabilities  are
measured using enacted tax rates in effect for the fiscal year in which those temporary differences are expected to be recovered or settled.
Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The  Company  operates  in  various  tax  jurisdictions  and  is  subject  to  audit  by  various  tax  authorities.  The  Company  provides  for  tax
contingencies whenever it is deemed probable that a tax asset has been impaired, or a tax liability has been incurred for events such as tax
claims  or  changes  in  tax  laws.  Tax  contingencies  are  based  upon  their  technical  merits  relative  tax  law  and  the  specific  facts  and
circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for
such tax contingencies.

The Company recognizes uncertain income tax positions taken on income tax returns at the largest amount that is more-likely than-not to
be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50%
likelihood of being sustained.

The Company’s policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of
our income tax provision. For the years ended December 31, 2017 and 2016, the Company did not record any material interest income,
interest expense or penalties related to uncertain tax positions or the settlement of audits for prior periods.

Stock-Based Compensation

The Company measures stock-based compensation expense related to employee stock-based awards based on the estimated fair value of
the  awards  as  determined  on  the  date  of  grant  and  is  recognized  as  expense  over  the  remaining  requisite  service  period.  The  Company
utilizes the Black-Scholes-Merton option pricing model to estimate the fair value of employee stock options. The Black-Scholes-Merton
model requires the input of highly subjective and complex assumptions, including the estimated fair value of the Company’s common stock
on the date of grant, the expected term of the stock option, and the expected volatility of the Company’s common stock over the period
equal to the expected term of the grant. The Company estimates forfeitures at the date of grant and revises the estimates, if necessary, in
subsequent periods if actual forfeitures differ from those estimates. The Company accounts for stock options to purchase shares of stock
that  are  issued  to  non-employees  based  on  the  estimated  fair  value  of  such  instruments  using  the  Black-Scholes-Merton  option  pricing
model. The measurement of stock-based compensation expense for these instruments is variable and subject to periodic adjustments to the
estimated fair value until the awards vest. Any resulting change in the estimated fair value is recognized in the Company’s consolidated
statements of operations during the period in which the related services are rendered.

Because  the  Company  was  a  privately-held  company  with  no  trading  history  prior  to  February  2014  and  has  limited  stock  history  since
February  2014,  the  Company  utilizes  the  historical  stock  price  volatility  from  a  representative  group  of  public  companies  to  estimate
expected  stock  price  volatility  and  our  historical  stock  price.  The  Company  selected  companies  from  the  medical  device  industry,
specifically those who are focused on the design, development and commercialization of products for the treatment of spine disorders, and
who  have  similar  characteristics  to  us,  such  as  stage  of  life  cycle  and  size.  The  Company  intends  to  continue  to  utilize  the  historical
volatility  of  the  same  or  similar  public  companies  to  estimate  expected  volatility  until  a  sufficient  amount  of  historical  information
regarding  the  price  of  our  publicly  traded  stock  becomes  available.  The  Company  uses  the  simplified  method  as  prescribed  by  the
Securities  and  Exchange  Commission  Staff Accounting  Bulletin  No.  107,  Share-based  Payment,  to  calculate  the  expected  term  of  stock
option grants to employees as the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to
estimate the expected term of stock options granted to employees. The Company utilizes a dividend yield of zero because the Company has
never paid cash dividends and has no current intention to pay cash dividends. The risk-free rate of return used for each grant is based on the
U.S. Treasury yield curve in effect at the time of grant for instruments with a similar expected life.

The Company accounts for stock options to purchase shares of stock that are issued to non-employees based on the estimated fair value of
such instruments using the Black-Scholes-Merton option pricing model. The measurement of stock-based compensation expense for these
instruments is variable and subject to periodic adjustments to the estimated fair value until the awards vest. Any resulting change in the
estimated fair value is recognized in the Company’s consolidated statements of operations during the period in which the related services
are rendered.

Offering Costs

Offering costs consist of legal, accounting, and other advisory costs related to the Company’s efforts to raise debt and equity capital.

Offering  costs  paid  in  cash  or  by  issuing  warrants  associated  with  the  Company’s  equity  fundraising  activities  are  either  recorded  to
additional paid in capital as a reduction of the proceeds or immediately expensed depending on the amount of the offering costs compared
to the gross proceeds.

Offering costs paid in cash or by issuing warrants associated with the Company’s debt fundraising activities are recorded as a debt discount
and amortized as interest expense over the lie of the debt or immediately expensed depending on the amount of offering costs compared to
debt, with the offset to additional paid in capital.

New Accounting Pronouncement, Not Yet Adopted

In August 2016, the Financial Accounting Standards Board (“FASB”) updated accounting guidance on the following eight specific cash
flow classification issues: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon debt instruments or other debt
instruments  with  coupon  interest  rates  that  are  insignificant  in  relation  to  the  effective  interest  rate  of  the  borrowing;  (3)  contingent
consideration  payments  made  after  a  business  combination;  (4)  proceeds  from  the  settlement  of  insurance  claims;  (5)  proceeds  from  the
settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) distributions received from equity
method  investees;  (7)  beneficial  interests  in  securitization  transactions;  and  (8)  separately  identifiable  cash  flows  and  application  of  the
predominance principle. Current GAAP does not include specific guidance on these eight cash flow classification issues. These updates are
effective for the Company for its annual period beginning January 1, 2019, and interim periods therein, with early adoption permitted. The
guidance in this standard is not expected to have a material impact on the consolidated financial statements.

In  March  2016,  the  FASB  updated  the  accounting  guidance  related  to  stock  compensation.  This  update  simplifies  the  accounting  for
employee  share-based  payment  transactions,  including  the  accounting  for  income  taxes,  forfeitures,  and  statutory  tax  withholding
requirements, as the well as classification in the statement of cash flows. The standard is effective for the Company for its annual period
beginning January 1, 2018. The guidance in this standard is not expected to have a material impact on the consolidated financial statements
of the Company.

In February 2016, the FASB updated the accounting guidance related to leases as part of a joint project with the International Accounting
Standards Board (“IASB”) to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities
on  the  balance  sheet  and  disclosing  key  information  about  leasing  arrangements.  Under  the  new  guidance,  a  lessee  will  be  required  to
recognize  assets  and  liabilities  for  capital  and  operating  leases  with  lease  terms  of  more  than  12  months. Additionally,  this  update  will
require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows
arising  from  leases,  including  qualitative  and  quantitative  requirements.  The  standard  is  effective  for  the  Company  for  its  annual  period
beginning January 1, 2020, and interim periods therein, with early adoption permitted. The Company is currently evaluating the potential
impact this new standard may have on its consolidated financial statements but believes the most significant change will relate to building
leases.

In May 2014, in addition to several amendments issued during 2016, the FASB updated the accounting guidance related to revenue from
contracts with customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle is that a
company  should  recognize  revenue  when  promised  goods  or  services  are  transferred  to  customers  in  an  amount  that  reflects  the
consideration to which an entity expects to be entitled for those goods or services. The standard defines a five-step process to achieve this
core  principle  and,  in  doing  so,  more  judgment  and  estimates  may  be  required  within  the  revenue  recognition  process  than  are  required
under existing U.S. GAAP. The standard is effective for the Company for its annual period beginning January 1, 2019, and interim periods
therein, and shall be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption.
The Company has yet to begin evaluation of the new accounting standard and therefore has yet to determine the impact, if any, that the
new standard will have on its consolidated financial statements.

In  January  of  2017,  the  FASB  issued ASU  2017-04— Intangibles—Goodwill  and  Other  (Topic  350) :  Simplifying  the  Test  for  Goodwill
Impairment.  The  amendments  in  this  guidance  to  eliminate  the  requirement  to  calculate  the  implied  fair  value  of  goodwill  to  measure
goodwill impairment charge (Step 2). As a result, an impairment charge will equal the amount by which a reporting unit’s carrying amount
exceeds its fair value, not to exceed the amount of goodwill allocated to the reporting unit. An entity still has the option to perform the
qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendment should be applied
on a prospective basis. The guidance is effective for goodwill impairment tests in fiscal years beginning after December 15, 2021. Early
adoption is permitted for goodwill impairment tests performed after January 1, 2017. The impact of this guidance for the Company will
depend on the outcomes of future goodwill impairment tests.

The Company has reviewed all other recently issued, but not yet adopted, accounting standards, in order to determine their effects, if any,
on  its  results  of  operations,  financial  position  or  cash  flows.  Based  on  that  review,  the  Company  believes  that  none  of  these
pronouncements will have a significant effect on its consolidated financial statements.

New Accounting Pronouncement, Adopted in 2017

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330) Simplifying the Measurement of Inventory”. The amendments clarify
that an entity should measure inventory within the scope of this update at the lower of cost and net realizable value. Net realizable value is
the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.
Substantial  and  unusual  losses  that  result  from  subsequent  measurement  of  inventory  should  be  disclosed  in  the  consolidated  financial
statements. This guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those annual
periods.  The  amendments  are  to  be  applied  prospectively  with  earlier  application  permitted  as  of  the  beginning  of  an  interim  or  annual
reporting period. The adoption of this guidance did not have a material impact on the consolidated financial statements.

Net Loss Per Share

Basic  net  loss  per  share  is  calculated  by  dividing  the  net  loss  by  the  weighted-average  number  of  common  shares  outstanding  for  the
period,  without  consideration  for  common  stock  equivalents.  Diluted  net  loss  per  share  is  calculated  by  dividing  the  net  loss  by  the
weighted-average  number  of  common  share  equivalents  outstanding  for  the  period  determined  using  the  treasury-stock  method.  Dilutive
common  stock  equivalents  are  comprised  of  convertible  preferred  stock,  warrants  for  the  purchase  of  convertible  preferred  stock  and
common stock, convertible notes, and stock options and restricted stock units outstanding under the Company’s equity incentive plans. For
all  periods  presented,  there  is  no  difference  in  the  number  of  shares  used  to  calculate  basic  and  diluted  shares  outstanding  due  to  the
Company’s net loss position.

Potentially  dilutive  securities  not  included  in  the  calculation  of  diluted  net  loss  per  share  because  to  do  so  would  be  anti-dilutive  are  as
follows (in common stock equivalent shares):

Finished  goods  include  consigned  inventory  of  approximately  $0.5  million  and  $5.6  million  as  of  December  31,  2017  and  2016,
respectively.  As  of  December  31,  2017,  inventories  totaling  $1.2  million  and  $1.1  million  were  classified  as  current  and  long-term,
respectively (all inventory was classified as current as of December 31, 2016). Inventories classified as current represent the carrying value
of inventories as of the date indicated, that management estimates will be sold during the following year. The above inventory totals are
recorded net of a provision for slow moving inventory of approximately $9.4 million and $4.8 million at December 31, 2017 and 2016,
respectively.  Included  in  cost  of  goods  sold  for  the  years  ended  December  31,  2017  and  2016  is  approximately  $4.6  million  and  $1.2
million, respectively, of cost relating to the provision for slow moving.

Management analyzed the undiscounted cash flows expected to be generated by the ceramic product line asset group and concluded that
due to continuing declining revenues that the carrying value of ceramic related assets exceeded the total of the undiscounted cash flows. As
a result, the Company recognized impairment charges of approximately $0.2 million related to its ceramics equipment, approximately $0.2
million  related  to  leasehold  improvements,  and  approximately  $0.5  million  related  to  its  ceramics  surgical  instrument  sets,  totaling  $0.9
million  of  impairment  charges  for  the  year  ended  December  31,  2016,  to  bring  the  carrying  value  to  the  estimated  fair  value.  No
impairment charge was recorded during the year ended December 31, 2017.

31, 2017 and 2016.

5. Fair Value Measurements

Financial Instruments Measured and Recorded at Fair Value on a Recurring Basis

The Company has issued certain warrants to purchase shares of common stock, which are considered mark-to-market liabilities and are re-
measured  to  fair  value  at  each  reporting  period  in  accordance  with  accounting  guidance.  Fair  value  is  based  on  the  price  that  would  be
received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date,
under a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

Level 1

- quoted market prices for identical assets or liabilities in active markets.

Level 2

- observable prices that are based on inputs not quoted on active markets but corroborated by market data.

Level 3

- unobservable inputs reflecting management’s assumptions, consistent with reasonably available assumptions made by

other market participants. These valuations require significant judgment.

The Company classifies assets and liabilities measured at fair value in their entirety based on the lowest level of input that is significant to
their fair value measurement. No financial assets were measured on a recurring basis as of December 31, 2017 and 2016. The following
tables set forth the financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy as of December
31, 2017 and 2016.

The Company has issued certain warrants to purchase shares of common stock, which are considered mark-to-market liabilities and are re-
measured to fair value at each reporting period in accordance with accounting guidance. As of December 31, 2017 and 2016, approximately
$0.5  million  of  the  derivative  liability  was  calculated  using  the  Black-Scholes-Merton  valuation  model. As  of  December  31,  2017  and
2016,  approximately  $0.9  million  and  $3.1  million  respectively,  were  calculated  using  the  Monte  Carlo  Simulation  valuation  model.
Issuances of common stock warrants deemed to be derivative liabilities during both of the years ended December 31, 2017 and 2016, were
valued at approximately $0.8 million and $5.8 million, respectively, on the date of issuance using the Monte Carlo Simulation valuation
model.

The assumptions used in estimating the common stock warrant liability using the Black-Scholes-Merton valuation model at December 31,
2017 and 2016 were as follows:

Weighted-average risk-free interest rate
Weighted-average expected life (in years)

In addition, if any time after the second anniversary of the issuance of the warrant, both: (1) the 30-day volume weighted average price of
the Company’s stock exceeds $3.00; and (2) the average daily trading volume for such 30-day period exceeds $0.4 million, the Company
may call this warrant for $0.01 per share. Because of the call provision, management believes the Monte Carlo Simulation valuation model
provides a better estimate of fair value for the warrants issued during 2017 and 2016 than the Black-Scholes-Merton valuation model.

Other Financial Instruments

The Company’s recorded values of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate
their  fair  values  based  on  their  short-term  nature.  The  recorded  value  of  notes  payable  approximates  the  fair  value  as  the  interest  rate
approximates market interest rates.

On July 28, 2017, the Company entered into a $2.5 million term loan (the “North Stadium Loan”) with North Stadium Investments, LLC
(“North Stadium”), a company owned and controlled by the Company’s Chief Executive Officer and Chairman of the Board. The North
Stadium Loan bears interest at 10% per annum and requires the Company to make monthly interest only payments from September 5, 2017
through July 5, 2018. All principal and unpaid interest (if any) under the North Stadium Loan is due and payable on July 28, 2018. The
North Stadium Loan is secured by substantially all of the Company’s assets but is junior to security interest in assets encumbered by the
Hercules  Term  Loan  (see  below).  In  connection  with  the  North  Stadium  Loan  the  Company  also  issued  North  Stadium  a  warrant  to
purchase up to 55,000 shares of the Company’s common stock at a purchase price of $5.04 per share, subject to a 5-year term. The relative
estimated value of the warrants on the date of grant approximated $0.2 million, which is being amortized as interest expense over the life of
the term loan.

Hercules Term Loan

On June 30, 2014, the Company entered into a Loan and Security Agreement with Hercules which provided the Company with a $20.0
million  term  loan.  The  Hercules  Term  Loan  matured  on  January  1,  2018.  The  Hercules  Term  Loan  included  a  $0.2  million  closing  fee,
which  was  paid  to  Hercules  on  the  closing  date  of  the  loan.  The  closing  fee  was  recorded  as  a  debt  discount  and  is  being  amortized  to
interest expense over the life of the loan. The Hercules Term Loan also includes a non-refundable final payment fee of $1.7 million. The
final payment fee is being accrued and recorded to interest expense over the life of the loan. The Hercules Term Loan bears interest at the
rate of the greater of either (i) the prime rate plus 7.7%, and (ii) 10.95%, provided however, that during an adjustment period, the term loan
interest rate shall mean for any day a per annum rate of interest equal to the grater of either (i) the prime rate plus 9.2%, and (ii) 12.45%.
The applicable rate was 11.95% as of December 31, 2017. Interest accrues from the closing date of the loan and interest payments are due
monthly.  Principal  payments  commenced  August  1,  2015  and  are  currently  being  made  in  equal  monthly  installments  totaling
approximately $0.5 million, with the remainder due at maturity. The Hercules Term Loan is secured by a first priority security interest in
substantially  all  of  its  assets,  including  intellectual  property,  of  the  Company  and  contains  covenants  restricting  payments  to  certain
Company affiliates and certain financial reporting requirements.

On September 8, 2015, the Company entered into a Consent and First Amendment to Loan and Security Agreement (the “Amendment”)
with Hercules. The Amendment modified the liquidity covenant to reduce the required minimum cash and cash equivalents balance by $0.5
million for every $1.0 million in principal paid, up to a minimum of $2.5 million. Once the Hercules Term Loan principal balance is below
$2.5 million the Company is only required to maintain a cash and cash equivalents balance equal to the outstanding principal balance on
the  Hercules  Term  loan.  The  minimum  cash  and  cash  equivalents  balance  required  to  maintain  compliance  with  the  minimum  liquidity
covenant  as  of  December  31,  2017,  was  approximately  $0.6  million.  Subsequent  to  December  31,  2017,  the  Company  entered  into  an
exchange  agreement  pursuant  to  which  the  Company  agreed  to  exchange  the  Hercules  Term  Loan  for  two  senior  secured  convertible
promissory notes (See Note 13).

See  discussion  below  with  respect  to  the  assignment  of  $3.0  million  of  the  principal  balance  of  the  Hercules  Term  Loan  to  Riverside
Merchant Partners, LLC (“Riverside”) and the subsequent agreement between the Company and Riverside to exchange the $3.0 million of
the  Hercules  Term  Loan  held  by  Riverside  for  subordinated  convertible  promissory  notes  in  the  aggregate  principal  amount  of  $3.0
million.

Hercules and Riverside Debt Exchange

On April 4, 2016, the Company entered into an Assignment and Second Amendment to Loan and Security Agreement (the “Assignment
Agreement”)  with  Riverside  and  Hercules,  pursuant  to  which  Hercules  sold  $1.0  million  of  the  principal  amount  outstanding  under  the
Hercules  Term  Loan  to  Riverside.  In  addition,  pursuant  to  the  terms  of  the  Assignment  Agreement,  Riverside  acquired  an  option  to
purchase an additional $2.0 million of the principal amount outstanding under the Hercules Term Loan from Hercules. On April 18, 2016,
Riverside exercised and purchased an additional $1.0 million of the principal amount of the Hercules Term Loan and on April 27, 2016,
Riverside  exercised  the  remainder  of  its  option  and  purchased  an  additional  $1.0  million  of  the  principal  amount  of  the  Hercules  Term
Loan from Hercules.

Riverside Debt

On April 4, 2016, the Company entered into an exchange agreement (the “Exchange Agreement”) with Riverside, pursuant to which the
Company  agreed  to  exchange  $1.0  million  of  the  principal  amount  outstanding  under  the  Hercules  Term  Loan  held  by  Riverside  for  a
subordinated convertible promissory note in the principal amount of $1.0 million (the “First Exchange Note”) and a warrant to purchase
8,333  shares  of  common  stock  of  the  Company  at  a  fixed  exercise  price  of  $19.56  per  share  (the  “First  Exchange  Warrant”)  (the
“Exchange”). All principal accrued under the Exchange Notes was convertible into shares of common stock at the election of the Holder at
any time at a fixed conversion price of $17.16 per share (the “Conversion Price”). The closing stock price on April 4, 2016, was $19.56 and
a  beneficial  conversion  feature  of  $0.2  million  was  recorded  to  equity  and  as  a  debt  discount.  The  warrant  value  of  $0.1  million  was
recorded to equity and as a debt discount.

In addition, pursuant to the terms and conditions of the Exchange Agreement, the Company and Riverside had the option to exchange an
additional $2.0 million of the principal amount of the Hercules Term Loan for an additional subordinated convertible promissory note in
the principal amount of up to $2.0 million and an additional warrant to purchase 8,333 shares of common stock (the “Second Exchange
Warrant”). The Exchange Agreement also provided that if the volume-weighted average price of the Company’s common stock was less
than  the  Conversion  Price,  the  Company  would  issue  up  to  an  additional  12,500  shares  of  common  stock  (the  “True-Up  Shares”)  to
Riverside, which was subsequently reduced to 11,667 shares of common stock.

On April 18, 2016, the Company and Riverside exercised their option to exchange an additional $1.0 million of the principal amount of the
Hercules  Term  Loan  for  an  additional  subordinated  convertible  promissory  note  in  the  principal  amount  of  $1.0  million  (the  “Second
Exchange Note”). The closing stock price on April 18, 2016, was $24.24 and a beneficial conversion feature of $0.4 million was recorded
to  equity  and  as  a  debt  discount. Additionally,  on April  27,  2016,  the  Company  and  Riverside  exercised  their  option  to  exchange  an
additional  $1.0  million  of  the  principal  amount  of  the  Term  Loan  for  an  additional  subordinated  convertible  promissory  note  in  the
principal  amount  of  $1.0  million  (the  “Third  Exchange  Note”)  and  an  additional  warrant  to  purchase  8,333  shares  of  the  Company’s
common  stock  at  a  fixed  exercise  price  of  $19.92  per  share.  The  warrant  value  of  $0.1  million  was  recorded  to  equity  and  as  a  debt
discount. The closing stock price on April 27, 2016, was $19.92 and a beneficial conversion feature of $0.3 million was recorded to equity
and as a debt discount. Financing costs were $0.3 million and were recorded to interest expense. The unamortized deferred financing costs
and  debt  discount  of  the  Hercules  Term  Loan  exchanged  were  $0.2  million  at  the  time  of  the  exchange  and  were  recorded  as  a  loss  on
extinguishment of debt related to the debt exchange. The First Exchange Note, the Second Exchange Note and the Third Exchange Note are
collectively referred to herein as the “Exchange Notes.”

F-20

 
 
 
 
 
 
 
 
 
 
 
 
Pursuant to the terms of the Exchange Notes, since the volume-weighted average price of the Company’s common stock was less than the
Conversion Price on May 6, 2016, the Company issued an additional 11,667 shares of common stock to Riverside and recorded the value of
the True-Up Shares of $0.2 million to interest expense and equity.

All principal outstanding under each of the Exchange Notes was to be due on April 3, 2018 (the “Maturity Date”). Each of the Exchange
Notes bore interest at a rate of 6% per annum, with the interest that would accrue on the initial principal amount of the Exchange Notes
during the first 12 months being guaranteed and deemed earned as of the date of issuance. Prior to the Maturity Date, all interest accrued
under the Exchange Notes was payable in cash or, if certain conditions were met, payable in shares of common stock at the Company’s
option, at a conversion price of $16.08 per share. During 2016, the entire principal amount of the First and Second Exchange Notes, $0.3
million of the Third Exchange Note, and the interest related to the First, Second, and Third Exchange Notes was converted into 145,227
shares of common stock. In July 2016, the Company paid Riverside $0.8 million to redeem in full the remaining principal balance of the
Third Exchange Note. The debt discounts associated with the converted debt was recorded to interest expense.

Magna Note

In July 2016, the Company paid Magna $0.9 million  to redeem in full the remaining principal balance and interest related to the Magna
Note. The outstanding principal amount of the Magna Note at extinguishment was $0.8 million. The Magna Note would have matured on
August 11, 2016, and accrued interest at an annual rate of 6.0%.

July 2016 Offering

In July 2016, the Company completed a secondary offering in which the Company sold 5,258,000 Class A Units, including 1,650,000 units
sold pursuant to the exercise by the underwriters of their over-allotment option, priced at $1.00 per unit, and 7,392 Class B Units, priced at
$1,000 per unit. Each Class A Unit consisted of 1/12th share of common stock and one warrant to purchase 1/12th share of common stock.
Each Class B Unit consisted of one share of preferred stock convertible into 83 shares of common stock and warrants to purchase 83 shares
of common stock. The securities comprising the units were immediately separable and were issued separately. In total, the Company issued
438,167  shares  of  common  stock,  7,392  shares  of  preferred  stock  convertible  into  616,000  shares  of  common  stock  and  warrants  to
purchase  1,054,167  shares  of  common  stock  at  a  fixed  exercise  price  of  $12.00  per  share.  The  Company  received  proceeds  of
approximately $11.4 million, net of underwriting and other offering costs.

The Company raised $4.9 million associated with the Class A Units, with $2.5 million, net of issuance costs of $0.3 million, allocated to
the common stock and $2.4 million allocated to the warrants. The Company also raised $7.0 million associated with the Class B Units with
$3.6 million, net of issuance costs of $0.4 million, allocated to preferred stock and $3.4 million allocated to the warrants. The $5.8 million
allocated to warrants were recorded as a derivative liability. In association with the warrants that were recorded as a derivative liability, the
Company immediately expensed approximately $0.5 million of issuance costs. The 7,392 preferred shares were convertible into 616,000
shares of common stock and had an effective conversion rate of $6.48 per share based on the proceeds that were allocated to them. The
stock  price  on  July  8,  2016,  was  $10.56  per  share  which  resulted  in  a  fair  value  in  excess  of  carrying  value  of  $4.08  per  share  or  $2.5
million in total. The fair value in excess of carrying value, or beneficial conversion feature, was recorded as an adjustment within equity
(e.g., deemed dividend). The Company recorded a non-cash, deemed dividend of $6.3 million ($2.5 and $3.8 million—calculated as $0.4
million  in  offering  costs  plus  $3.4  million  measured  as  the  difference  between  the  stated  value  and  the  allocated  proceeds)  related  to  a
beneficial conversion feature and accretion of a discount on convertible preferred stock.

Subsequent to the secondary offering, all 7,392 shares of convertible preferred stock have been converted into 616,000 shares of common
stock. Furthermore, the Company received $0.4 million and issued 37,208 shares of common stock upon the exercise of certain warrants
issued in the secondary offering.

Other Issuance

On April  1,  2016,  Hampshire  MedTech  Partners  II,  GP  (“Hampshire  GP”)  filed  suit  against  the  Company  in  the  Travis  County,  Texas
200th  Judicial  District  Court  relating  to  a  Warrant  to  Purchase  Shares  of  Common  Stock  issued  to  Hampshire  MedTech  Partners  II,  LP
(“Hampshire LP”) on November 6, 2014 (the “Warrant”). Hampshire GP alleged that as a result of a subsequent financing the Company
breached the anti-dilution provision of the Warrant by failing to increase the number of shares subject to the Warrant as well as failing to
reduce the exercise price of the Warrant. In November 2016, the Company and Hampshire GP settled the lawsuit through the execution of
a Settlement Agreement and Release. Pursuant to the terms of settlement, the Company issued 80,198 shares of common stock with a fair
value of $794,000 and the pre-existing warrants held by Hampshire GP were cancelled. The value of the shares issued were recognized as
loss on settlement in the consolidated statements of operations.

During 2016, 156,893 shares of common stock were issued related to the Riverside Debt discussed in Note 7.

The  Company  estimates  the  fair  value  of  each  stock  option  on  the  grant  date  using  the  Black-Scholes-Merton  valuation  model,  which
requires several estimates including an estimate of the fair value of the underlying common stock on grant date. The expected volatility
was based on an average of the historical volatility of a peer group of similar companies. The expected term was calculated utilizing the
simplified method. The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant for the expected term
of  the  option.  The  following  weighted  average  assumptions  were  used  in  the  calculation  to  estimate  the  fair  value  of  options  granted  to
employees during the year ended December 31, 2016, (no options were granted for the year ended December 31, 2017):

At  December  31,  2017  and  2016,  the  Company  had  net  operating  loss  carryforwards  for  federal  and  state  income  tax  purposes  of
approximately  $167.7  million  and  $160.2  million,  respectively.  The  federal  and  state  net  operating  loss  carryforwards  will  expire  from
2023  to  2037,  unless  previously  utilized. Additionally,  the  Company  believes  an  ownership  change  has  occurred  that  would  trigger  the
limitation on usage of net operating losses imposed by Internal Revenue Code section 382. Because of this limitation, a significant portion
of the net operating losses would more likely than not expire unused.

During  the  years  ended  December  31,  2017  and  2016,  the  Company  recognized  no  amounts  related  to  interest  or  penalties  related  to
uncertain tax positions. The Company is subject to taxation in the United States and various state jurisdictions. The Company currently has
no years under examination by any jurisdiction.

A  valuation  allowance  has  been  established  as  realization  of  such  deferred  tax  assets  has  not  met  the  more  likely-than-not  threshold
requirement. If the Company’s judgment changes and it is determined that the Company will be able to realize these deferred tax assets, the
tax benefits relating to any reversal of the valuation allowance on deferred tax assets will be accounted for as a reduction to income tax
expense.  The  tax  valuation  allowance  decreased  by  approximately  $20.7  million  and  increased  by  $5.6  million  for  the  years  ended
December 31, 2017 and 2016, respectively.

Recent Tax Legislation

On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Reform Act”) was signed into law by the President of the United States. The Tax
Reform Act significantly revised the U.S. corporate income tax regime by, among other things, lowering the U.S. federal corporate tax rate
from  35%  to  21%  effective  for  our  calendar  year  ending  December  31,  2018.  U.S.  GAAP  requires  that  the  impact  of  tax  legislation  be
recognized in the period in which the law was enacted.

The  Tax  Reform  Act  reduces  the  federal  corporate  tax  rate  to  21%  effective  for  our  calendar  year  ending  December  31,  2018.  We
recognized the effects of the Tax Reform Act for the re-measurement of the net deferred tax liabilities during the year ended December 31,
2017.

We recognized the income tax effects of the Tax Reform Act in our 2017 financial statements in accordance with Staff Accounting Bulletin
No. 118 (“SAB 118”), which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in
which  the  2017  Tax  Reform Act  was  signed  into  law.  The  guidance  addresses  how  a  company  recognizes  provision  amounts  when  a
company  does  not  have  the  necessary  information  available,  prepared  or  analyzed  (including  computations)  in  reasonable  detail  to
complete its accounting for the effect of the changes in the Tax Reform Act. As such, the financial results reflect the income tax effects of
the  Tax  Reform Act  for  which  the  accounting  under ASC  Topic  740  is  complete  and  provisional  amounts  for  those  specific  income  tax
effects  of  the  Tax  Reform Act  for  which  the  accounting  under ASC  740  is  incomplete,  but  a  reasonable  estimate  could  be  determined.
Pursuant  to  the  SAB  118,  we  are  allowed  a  measurement  period  of  up  to  one  year  after  the  enactment  date  of  the  Tax  Reform Act  to
finalize the recording of the related tax impacts.

11. Commitment and Contingencies

The  Company  currently  leases  laboratory,  manufacturing  and  office  space  and  equipment  under  noncancelable  operating  leases  which
provide for rent holidays and escalating payments; this lease ends 2019. Lease incentives, including rent holidays, allowances for tenant
improvements  and  rent  escalation  provisions,  are  recorded  as  deferred  rent.  Rent  under  operating  leases  is  recognized  on  a  straight-line
basis beginning with lease commencement through the end of the lease term. Sublease income is recorded as a reduction of rent expense.
For each of the years ended December 31, 2017 and 2016, rental expense was $1.0 million and $0.6 million, respectively. Sublease income
was $0.1 million and $0.1 million during both of the years ended December 31, 2017 and 2016.

The  following  table  summarizes  future  minimum  rental  payments  required  under  operating  leases  that  have  initial  or  remaining  non-
cancelable lease terms in excess of one year as of December 31, 2017 (in thousands):

The Company has entered into consulting and development agreements with some of its advisors, including some surgeon advisors. The
Company has agreed to pay some of the surgeon advisors a portion of the net profits attributable to the sale of specific spine products for
which  the  surgeon  advisors  provided  the  Company  with  consulting  and  related  services  related  to  the  conceptualization,  development,
testing,  clearance,  approval  and/or  related  matters  involving  implant  products.  The  Company  is  obligated  to  pay  royalties  to  different
surgeon advisors in connection with the sale of certain of its implant products. These agreements generally continue until the later of (a) ten
years from the date of the agreements, and (b) the expiration of the patent rights relating to the devices covered by the agreements, when
rights have been assigned by the individuals to the Company. The Company incurred royalties of $0.3 million and $0.06 million related to
these  agreements  for  the  years  ended  December  31,  2017  and  2016,  respectively.  None  of  the  royalty  arrangements  contain  minimum
royalty payments.

On  May  13,  2015,  the  Company  entered  into  a  joint  agreement  for  research  and  development  of  silicon  nitride-based  devices.  This
agreement is effective for a period of five years from the date of commencement. The Company incurred payments of $0.03 million related
to this agreement for each of the years ended December 31, 2017 and 2016.

The  Company  has  executed  agreements  with  certain  executive  officers  of  the  Company  which,  upon  the  occurrence  of  certain  events
related to a change in control, call for payments to the executives up to three times their annual salary and accelerated vesting of previously
granted stock options.

From time to time, the Company is subject to various claims and legal proceedings covering matters that arise in the ordinary course of its
business  activities.  Management  believes  any  liability  that  may  ultimately  result  from  the  resolution  of  these  matters  will  not  have  a
material adverse effect on the Company’s consolidated financial position, operating results or cash flows.

12. 401(k) Plan

Effective June 1, 2004, the Company adopted a defined contribution retirement plan under Section 401(k) of the Internal Revenue Code.
The plan covers substantially all employees. Eligible employees may contribute amounts to the plan, via payroll withholdings, subject to
certain limitations. The plan permits, but does not require, additional matching contributions to the plan by the Company on behalf of the
participants in the plan. The Company incurred approximately $0.1 million relating to retirement contributions for each of the years ended
December 31, 2017 and 2016.

13. Restatement to Previously Issued 2016 Consolidated Balance sheet and Related Statements of Operations, Stockholders’ Equity
and Cash Flows

The Company previously restated and re-issued (on December 26, 2017) the 2016 consolidated financial statements because of the failure
to record a derivative liability from the issuance of 1,054,167 common stock warrants during July 2016 that were previously recorded as
equity.  The impact of this change as of and for the year ended December 31, 2016, is as follows (in thousands, except share and per share

For  the  twelve  months  ended  December  31,  2016,  the  consolidated  statement  of  cash  flows  changed  from  that  which  was  previously
reported as follows: A $571,000 positive addback for offering costs was recorded to offset a $571,000 increase to net loss, with no net cash
impact on cash flows from operating activities. In addition, the allocation of proceeds among common stock, preferred stock and derivative
liability changed, with no net cash flow impact on cash flows from financing activities.

14. Restatement to Previously Issued 2017 Condensed Consolidated Financial Statements

Subsequent  to  the  issuance  of  the  condensed  consolidated  financial  statements  as  of  March  31,  2017,  June  30,  2017  and  September  30,
2017, and for the three, six and nine-month periods then ended, the Company identified errors related to a failure to record a derivative
liability  from  the  issuance  of  1,054,167  common  stock  warrants  during  July  2016  and  the  issuance  of  333,750  common  stock  warrants
during  January  2017  that  were  previously  recorded  as  equity.  The  impact  of  this  change  to  the  Company’s  previously  issued  condensed
consolidated financial statements as of and for the above outlined periods were restated in amended Quarterly Reports on Form 10-Q/A. 
The impact of these changes for the above-mentioned periods are repeated below (in thousands, except share and per share data):

15. Subsequent Events

On January 3, 2018, the Company entered into an exchange agreement pursuant to which the Company agreed to exchange the Hercules
Term Loan (see Note 7) for two senior secured convertible promissory notes each in the principal amount of $1.1 million for an aggregate
principal amount of $2.2 million, (the “Exchange Notes”). The Exchange Notes will mature on February 3, 2019 (the “Maturity Date”).
The Exchange Notes bear interest at a rate of 15% per annum. Prior to the Maturity Date, principal and interest accrued under the Exchange
Notes is payable in cash or, if certain conditions are met, payable in shares of common stock of the Company. All principal accrued under
the Exchange Notes is convertible into shares of the Company’s common stock (“Conversion Shares”) at the election of the holders at any
time at a fixed conversion price of $3.87 per share. Upon the occurrence of an event of default, the Assignees are entitled to convert all or
any part of their Exchange Note at a conversion price (the “Alternate Conversion Price”) equal to 70% of the lowest traded price of the
Company’s  common  stock  during  the  ten  trading  days  prior  to  the  conversion  date,  provided  that  (i)  in  no  event  may  the  Alternate
Conversion Price be less than $1.75 per share and (ii) the Assignees shall not be entitled to receive more than 19.99% of the outstanding
Common  Stock.  So  long  as  this  Exchange  Notes  remains  outstanding  or  the Assignees  hold  any  Conversion  Shares,  the  Company  is
prohibited from entering into any financing transaction pursuant to which the Company sells its securities at a price lower than $1.75 per
share.

On January 31, 2018, the Company signed a promissory note in the aggregate principal amount of up to $0.8 million (the “Note”) for an
aggregate  purchase  price  of  up  to  $0.7  million  and  warrants  to  purchase  up  to  an  aggregate  of  68,257  shares  of  common  stock  of  the
Company (the “Warrants”) at an exercise price of $3.31 per share. The maturity date is six months from date of funding. The Note bears
interest at a rate of 8% per year and a default interest rate of 18% per year. The Note may be converted by the holder of the Note at any time
following an event of default. The conversion price of the Note in the event of a default is equal to the product of (i) 0.70 multiplied by (ii)
the lowest volume weighted average price, or VWAP, of the Company’s common stock during the 20 trading period ending in the Holder’s
sole discretion on the last complete trading day prior to conversion, or, the conversion date.

 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
      
  
 
 
      
  
 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 
 
 
 
 
      
  
 
 
      
  
 
 
 
 
 
 
 
   
 
 
 
 
 
On  March  6,  2018,  the  “Company  entered  into  a  warrant  amendment  agreement  (the  “Amendment Agreement”)  with  certain  holders  of
previously issued Series E Common Stock Purchase Warrants (collectively, “Investor”). In connection with that certain Series E Common
Stock Purchase Warrant between the Company and Investor dated July 8, 2016, the Company issued to Investor warrants to purchase up to
832,000  shares  of  common  stock  (the  “Warrant  Shares”)  at  an  exercise  price  of  $12.00  per  share,  (the  “Investor  Warrants”).  Under  the
terms of the Amendment Agreement, in consideration of Investor exercising 600,000 of the Investor Warrants (the “Warrant Exercise”),
the  exercise  price  per  share  of  the  Investor  Warrants  was  reduced  to  $2.125  per  share.  In  addition,  and  as  further  consideration,  the
Company issued to Investor warrants to purchase up to the number of shares of common stock equal to 100% of the number of Warrant
Shares issued pursuant to the Warrant Exercise at an exercise price per share equal to $2.00 per share. The New Warrants are exercisable
for  up  to  five  years  from  the  Effective  Date.  The  Company  also  granted  to  an  advisor  to  the  transaction  securities  purchase  warrants
covering a number of shares of the Company’s common stock equal 1.5% of the total number of shares of the Company’s common stock
underlying the Investor Warrants.
