Our products are used by orthopedic spine surgeons and neurosurgeons to treat a variety ofspinal disorders in the cervical, thoracolumbar, and interbody spine. Our Offices Our headquarters and manufacturing facility are located at 664 Cruiser Lane, Belgrade, Montana 59714. Our telephone number is (406) 388-0480.We also have two other facilities on the Montana campus, located at 600 Cruiser Lane, Belgrade, Montana 59714, and at 732 Cruiser Lane, Belgrade,Montana 59714. All our properties are leased. Our Corporate History We began operations in 1998 as a spin out of the Center for Biofilm Engineering at Montana State University, or the CBE, and incorporated as“Bacterin, Inc.” in the state of Montana in January 2000. Through a series of transactions and corporate events, we eventually became Bacterin InternationalHoldings, Inc. (“Bacterin”), which on March 7, 2011, began trading our common stock on the NYSE Amex, now known as the NYSE American under theticker symbol “BONE.” On July 31, 2015, we acquired all of the outstanding capital stock of X-spine Systems, Inc. (“X-spine”) for approximately $60 million in cash,repayment of approximately $13 million of X-spine debt, and approximately 4.24 million shares (0.4 million shares post reverse split) of Xtant commonstock. X-spine is engaged in the development, manufacturing and sale of implants and medical devices for use in orthopedic spinal surgeries. As a result ofthis transaction, X-spine became a wholly owned subsidiary of Bacterin International Holdings, Inc. 4 At the close of business on July 31, 2015, we changed our corporate name to “Xtant Medical Holdings, Inc.” On August 6, 2015, Xtant formed a newwholly owned subsidiary, Xtant Medical, Inc., a Delaware corporation to facilitate the integration of Bacterin and X-spine. On October 15, 2015, our commonstock began trading on the NYSE MKT under the ticker symbol “XTNT.” X-spine is engaged in the development, manufacturing and sale of implants andmedical devices for use in orthopedic spinal surgeries. Xtant, Bacterin and X-spine are jointly referred to herein as the “Company”. On May 8, 2017, the Company entered into an agreement with Aurora Management Partners Inc. (“Aurora”) to assist us in restructuring efforts.Pursuant to this agreement, David Baker served as Chief Restructuring Officer of the Company and certain additional Aurora personnel, referred to as DeputyRestructuring Officers, assisted in the restructuring efforts. As part of our restructuring, we completed a significant debt restructuring in the beginning of 2018pursuant to which then outstanding indebtedness amounting to an aggregate of $76.6 million in principal, together with accrued and unpaid interest, wasconverted into shares of our common stock and we issued an additional 946 thousand shares of common stock to certain of our lenders in a privateplacement. As a result of this debt restructuring, ROS Acquisition Offshore LP (“ROS”) and OrbiMed Royalty Opportunities II, LP (“Royalty Opportunities”and together with ROS, our “lenders”), which are funds affiliated with OrbiMed Advisors LLC (“OrbiMed”), collectively own approximately 70% of ouroutstanding common stock. Although our agreement with Aurora terminated on November 8, 2018 and David Baker no longer serves as Chief RestructuringOfficer, certain Aurora personnel continue to provide financial and accounting assistance to us under a separate agreement. Industry and Market Overview The orthopedic biomaterials market consists of materials that are organic, inorganic or synthetic in nature. These materials are implanted or appliedin or near the indicated bone to facilitate healing, encourage bone tissue augmentation, compensate in areas where bone tissue is depleted and restorestructure to allow for repair. Orthopedic biomaterials are capable of producing specific biological action or regenerative responses that are beyond what isobserved in normal healing. These materials are often used as substitutes to autograft materials, which are taken from a harvest site in the patient to patch orrepair the wounded or unhealthy site. Fixation is often instrumental in allowing the body to heal and regenerate tissue. It provides the constructive support necessary for reestablishingstability, by immobilizing the regenerative site, and relieving stress. Fixation can also help hold the biomaterial in place in order to achieve a better outcome.Examples of fixation products can include, but is not limited to, plates, screws, pins, rods, spacers, and staples, and may be made from various metals andpolymer materials. How We Compete We believe the following allow us to compete in the marketplace: ●Broad Portfolio of Products: We have a comprehensive portfolio of products that address a broad array of spinal pathologies, anatomies andsurgical approaches in the complex spine and minimally invasive surgery (“MIS”) markets. To protect company innovative technologies andtechniques, we maintain and plan to continue to grow our intellectual property portfolio. ●Customer Service: Responding quickly and efficiently to the needs of patients, surgeons and hospitals is central to our corporate culture and criticalto our success. Our supply chain and customer service teams work together to make sure that the right product and instrumentation is in the rightplace at the right time. Through such vertically integrated processes, we strive to meet the changing needs of our customers. ●National Distribution Network: Xtant has built a distribution channel function calling on orthopedic surgeons, neuro surgeons, their staff and thehospital administrators that support them. Over 300 commissioned independent agents and stocking agents in the United States represent some or allof Xtant’s products. We also maintain a national accounts program to enable our agents to gain access to independent health delivery networkhospitals and through group purchasing organizations. 5 Our Orthobiologics Products Our biomaterial products include OsteoSponge®, OsteoSponge® SC, OsteoSelect® DBM putty, OsteoSelect Plus DBM putty, OsteoWrap®,OsteoSTX®, and our new line of 3Demin® products, as described below, as well as other allografts: ●OsteoSponge is a form of demineralized bone matrix made from 100% human bone. Derived from trabecular (cancellous) bone, OsteoSpongeprovides a natural scaffold for cellular in-growth and exposes bone-forming proteins to the healing environment. The malleable properties ofOsteoSponge enable it to conform to, and fill, most defects. Upon compressing the allograft, OsteoSponge springs back to completely fill the void.Its unique mechanical and biological properties make OsteoSponge an ideal bone graft for use in various orthopedic practices including spine,neurology, cranial/maxillofacial, trauma, plastic/reconstruction and general procedures where new bone growth is needed. ●OsteoSponge SC is a form of OsteoSponge designed to fill bony defects in the subchondral region of joints. We have received permission from theU.S. Food and Drug Administration (“FDA”), which is a Federal agency of the United States Department of Health and Human Services, to marketthis product as a subchondral bone void filler and are currently marketing it as such. ●OsteoSelect DBM Putty is engineered with the surgeon in mind. With outstanding handling characteristics, OsteoSelect is designed to be easilymolded into any shape and compressed into bony voids. Bacterin has validated a low-dose, low-temperature gamma sterilization process to providemaximum osteoinductive potential while still affording device level sterility. Every production batch of OsteoSelect is tested for osteoinductivebone growth characteristics allowing us to make that unique marketing claim. ●OsteoSelect PLUS combines the exceptional cohesive characteristics of OsteoSelect DBM Putty with demineralized cortical chunks. OsteoSelectPLUS is designed to deliver differentiated handling properties and insure patient safety through validated, terminal sterilization. Each lot ofOsteoSelect PLUS DBM is tested for osteoinductivity in vivo prior to being released. OsteoSelect PLUS is indicated as a bone void filler and bonegraft substitute in the pelvis, extremities, and posterolateral spine. ●OsteoWrap is 100% human cortical bone demineralized through a proprietary process to make the graft flexible while maintaining allograftintegrity. This product has various applications in orthopedic, neurological, trauma, oral/maxillofacial and reconstructive procedures. OsteoWrapcan wrap around non-union fractures to assist with fusion, can act as a biologic plate or can be used in conjunction with a hardware plate system.Additionally, this product provides the surgeon with superior handling characteristics as the allograft can be easily sized using surgical scissors or ascalpel and will withhold sutures or staples for fixation. ●OsteoSTX are demineralized cortical sticks processed from human allograft bone. Utilizing our patented demineralization technology, the grafts areflexible and feature osteoinductive properties. The nature of demineralized cortical bone provides all the necessary elements for bone regeneration.OsteoSTX are designed for posterolateral spine surgery applications ranging from one-level to multi-level fusions, including scoliosis procedures. ●3Demin is a family of allografts that maximizes osteoconductivity and the osteoinductive potential of human bone. They consist of 100%demineralized cortical bone with excellent, malleable handling characteristics, and are distributed as a sterile allograft. Bacterin’s 3Demin productsare easily hydrated with any biocompatible liquid, making them an ideal option for various bone grafting applications. They are most commonlyused in spinal fusion procedures. All of our biologics are terminally sterilized and packaged to enhance the safety of our grafts for our physician customers and their patients. 6 We also process and distribute (i) sports allografts which are processed specifically for anterior and posterior cruciate ligament repairs, anteriorcruciate ligament reconstruction and meniscal repair, (ii) milled spinal allografts which are comprised of cortical bone milled to desired shapes anddimensions, and (iii) traditional allografts for multi-disciplinary applications including orthopedics, neurology, podiatry, oral/maxillofacial, genitourinaryand plastic/reconstructive. Our related biologic products are described in multiple physician-initiated studies that continue to prove expanded indications for their use. Thesedocuments are available through our website at www.xtantmedical.com. Information contained on our website does not constitute part of this Form 10-K. Our Spinal Implant Products We offer a comprehensive line of products that are used to treat a variety of spinal and sacroiliac conditions, including trauma, degeneration,deformity and tumor, including use of Minimally Invasive Surgery techniques. Some of our key spinal implant product lines include: Cervical Products ●The CertexTM Spinal Fixation System consists of screws, hooks, rods, and cross connectors. Various sizes of these implants are available so thatadaptations can be made to take into account pathology and individual patient anatomy.

It isintended for spinal fusion procedures at one or two contiguous levels of the lumbosacral spine (L2 − S1 inclusive) in skeletally mature patients forthe treatment of degenerative disc disease. Technology and Intellectual Property We rely upon patents, trademarks, and trade secrets to maintain and improve our competitive position. We review third-party proprietary rights,including patents and patent applications, as available, to develop an effective intellectual property strategy, avoid infringement of third-party proprietaryrights, identify licensing opportunities and monitor the intellectual property owned by others. Patents Our policy is to file patent applications in the United States and other countries when we believe it is commercially advantageous to do so. We donot consider our business to be materially dependent upon any individual patent. As of December 31, 2018, our fixation patent portfolio includes over 53 issued patents globally and 1 patent application pending, and our biologicspatent portfolio includes over 14 issued patents globally and over 12 patent applications pending. We expect that additional patent applications will be filed and prosecuted as inventions are discovered, technological improvements and processesare developed, and specific applications are identified. There can be no assurance that we will be able to obtain final approval of any patents. Trademarks We have registered, and continue to seek registration, of trademarks and continuously monitor and aggressively pursue users of names and marksthat potentially infringe upon our registered trademarks. We currently own the following registered trademarks under the Bacterin name: OsteoSponge ®,OsteoVine ®, OsteoWrap ®, OsteoLock ®, BacFast ®, OsteoSelect ®, Elutia ®, OsteoSTX ®, hMatrix ®, 3Demin®, BACTERINSE ®, and Circle of Life ®.Under the X-spine name, we own the following registered trademarks: SILEX®, X-SPINE®, IRIX®, CAPLESS®, CERTEX®, CALIX®, H-GRAFT®, SPIDER,X90®, HYDRAGRAFT®, BUTREX®, FORTEX®, AXLE®, FIXCET®, Capless® and X-spine’s square design logo. Trade Secrets To safeguard our proprietary knowledge and technology, we rely upon trade secret protection and non-disclosure/confidentiality agreements withemployees, consultants and third-party collaboration partners with access to our confidential information. There can be no assurance, however, that thesemeasures will adequately protect against the unauthorized disclosure or use of confidential information, or that third parties will not be able to independentlydevelop similar technology. Additionally, there can be no assurance that any agreements concerning confidentiality and non-disclosure will not be breached,or if breached, that we will have an adequate remedy to protect us against losses. Although we believe our proprietary technology has value, because of rapidtechnological changes in the medical industry, we also believe that proprietary protection is of less significance than factors such as the intrinsic knowledgeand experience of our management, advisory board, consultants and personnel and their ability to identify unmet market needs and to create, invent, developand market innovative and differentiated products. 8 Donor Procurement We have agreements with multiple recovery agencies, and we continue to expand our network for access to donor tissue in anticipation of increaseddemand. We expect to be able to continue to build our network for donor tissue as our processing capabilities and sales increase. Sales and Marketing We distribute our products in the United States through a distribution network of over 300 commissioned independent sales agents and stockingagents. We also maintain a national accounts program to enable our agents to gain access to independent health delivery network hospitals and throughgroup purchasing organizations. Our international footprint includes distribution partners in Canada, Mexico, South America, Europe, Australia, and certain Pacific region countries. Competition There are various public and private organizations that offer both, fixation and orthobiologics to their customers. The market is dominated by largecompetitors including Medtronic plc, Johnson and Johnson, Zimmer Biomet Holdings, Inc., Nuvasive, Inc., and Globus Medical, Inc. Together, we believethese large competitors have almost 80% market share. We compete with these larger competitors and several others including RTI Surgical, Inc., SeaSpineHoldings Corporation, OrthoFix Medical Inc., Alphatec Holdings, Inc., as well as dozens of privately-owned companies. We also compete with tissue banksthat do not offer spinal fixation products, such as AlloSource International, Inc., LifeNet Health, and MTF Biologics. Government Regulation We are registered with the FDA as a manufacturer of human cellular and tissue products (“HCT/Ps”) as well as medical devices, and we are anaccredited member in good standing of the American Association of Tissue Banks. We meet all licensing requirements for the distribution of HCT/Ps in stateswith licensing requirements, including Florida, California, Delaware, Illinois, Louisiana, Maryland, Oregon, and New York. Our industry is highly regulated,and we cannot predict the impact of future regulations on either us or our customers. Our fixation products and instrumentation systems are regulated as medical devices and therefore are subject to extensive regulation by the FDA, aswell as by other domestic and international regulatory bodies. These regulations govern multiple activities that Xtant and suppliers, licensors and partnersperform and will continue to perform. These regulated activities include product design and development, testing, manufacturing, labeling, storage, safety,premarket clearance, advertising and promotion, product marketing, sales and distribution, post-market surveillance and post-market adverse event reporting.All products currently marketed by Xtant are regulated as HCT/Ps or have received 510(k) clearances. 9 Human Tissue Human tissue products have been regulated by the FDA since 1993. In May 2005, three new comprehensive regulations went into effect that addressmanufacturing activities associated with HCT/Ps. The first requires that companies that produce and distribute HCT/Ps register with the FDA. The secondprovides criteria that must be met for donors to be eligible to donate tissues and is referred to as the “Donor Eligibility” rule. The third rule governs theprocessing and distribution of the tissues and is often referred to as the “Current Good Tissue Practices” rule. Together, they are designed to ensure thatsound, high quality practices are followed to reduce the risk of tissue contamination and communicable disease transmission to recipients. Several of ourproducts including OsteoSponge and OsteoWrap are regulated as HCT/Ps as determined by the Tissue Reference Group and regulated under Section 361 ofthe Public Health Service Act (“PHSA”) and 21 CFR Part 1271. Medical Devices Our medical devices require the clearance of the FDA prior to sale within the United States. The FDA process requires a premarket notification, or a510(k) submission, to the FDA to demonstrate that the medical device is safe and effective and is substantially equivalent to a legally marketed device that isnot subject to premarket approval. Applicants must compare the device to one or more similar devices that are commercially available in the United States(known as the “predicate device”) and make and support a claim of substantial equivalency to such predicate device. Support for such claims must includedescriptive data and, when necessary, performance data. In some cases, data from clinical trials must also be submitted in support of a 510(k) submission. TheFDA must then issue an order finding substantial equivalency before the devices may be commercially distributed in the United States. The Center forDevices and Radiological Health Division of the FDA governs HCT/Ps that are regulated as medical devices, including our OsteoSelect DBM putty. The discussion of what data is needed is sometimes conducted in a formal process called the Pre-Submission process whereby companies meet withthe FDA to discuss the data needed for clearance. If the FDA finds the applicant’s device is substantially equivalent to the predicate device, it will send aletter to the applicant stating that fact. This allows the applicant’s device to be commercially distributed in the United States. The Center for Devices andRadiological Health division of the FDA governs the clearance of conventional medical devices such as our spinal hardware as well as some of the HCT/Psthat are also regulated as medical devices, such as our OsteoSelect DBM putty. Another procedure for obtaining marketing authorization for a medical device is the “de novo classification” procedure. If the FDA agrees that thedevice is substantially equivalent to a predicate device currently on the market, it will grant 510(k) clearance to commercially market the device. If the FDAdetermines that the device is “not substantially equivalent” to a previously cleared device, the device is automatically designated as a Class III device. Thedevice sponsor must then fulfill more rigorous premarket approval or “PMA” requirements or can request a risk-based classification determination for thedevice in accordance with the “de novo” process, which is a route to market for novel medical devices that are low to moderate risk and are not substantiallyequivalent to a predicate device. A company files for a de novo approval when it does not have a predicate to which it can claim substantial equivalence.Once a de novo application is reviewed and approved, it results in the device having a Class II status and future devices from the company or a competitormay use the company de novo-approved device as a 510(k) predicate. A de novo approval is reserved for Class II moderate risk devices and a company mustshow that special controls can be created which subsequent applicants can follow to obtain a 510(k) clearance. The advantage of the de novo approval is thatit requires less data than a PMA. The disadvantage is that it may require more data than a 510(k) and most often will include human clinical data. FDA isincreasingly moving devices with slightly different proposed indication statements or different technological features off the 510(k) path and on to the denovo path resulting in more time and expense for the company. 10 The process of obtaining regulatory clearances or approvals to market a medical device can be costly and time-consuming, and we may not be ableto obtain these clearances or approvals on a timely basis, if at all. Products that are approved through a PMA application generally need FDA approval beforethey can be modified. Similarly, some modifications made to products cleared through a 510(k) may require a new 510(k) or a PMA. In the future, Xtant may decide to strategically commercialize products in the United States that would require a PMA, but there are no plans to do soat the present time. Clinical trials are almost always required to support a PMA. International Regulation Many foreign countries have regulatory bodies and restrictions similar to the FDA. International sales are subject to foreign government regulation,the requirements of which vary substantially from country to country. The time required to obtain approval in a foreign country or to obtain a CE Certificateof Conformity may be longer or shorter than that required for FDA approval and the related requirements may differ. Some third-world countries accept CECertificates of Conformity or FDA clearance or approval as part of applications of approval for marketing of medical devices in their territory. Othercountries, including Brazil, Canada, Australia and Japan, require separate regulatory filings. To market our product devices in the member countries of the European Union, we are required to comply with the European Medical DeviceDirectives and to obtain CE mark certification. CE mark certification is the European symbol of adherence to quality assurance standards and compliancewith applicable European Medical Device Directives. Under the European Medical Device Directives, all medical devices must qualify for CE marking. Toobtain authorization to affix the CE mark to one of our products, a recognized European Notified Body must assess our quality systems and the product’sconformity to the requirements of the European Medical Device Directives. We are subject to inspection by the Notified Bodies for compliance with theserequirements. In March 2019, our Notified Body informed us that we are at risk of losing our CE mark on several products for failing to comply with postmarket clinical follow up requirements. We are working with our Notified Body to remediate this nonconformance. There can be no assurance that we will beable to remediate this matter on a timeline that is satisfactory to the Notified Body. If this risk were to materialize, we may be required to remove the effectedproducts from the EU market countries until remediation is complete. The new European MDR intended to replace the current Medical Device Directives came into force May 2017. Manufacturers of approved medicaldevices will have until May 2020 to transition their devices to meet the requirements of the MDR. After May 2020, manufacturers are offered a grace periodwhich further extends the transition time for some medical devices. We are currently reviewing our product portfolios, quality system and processes in aneffort to meet the new regulations within the timeframes we are afforded, although no assurance can be provided that we will be able to do so. Our failure tomeet these new regulations would cause us to lose our CE mark certification. Healthcare Fraud and Abuse Healthcare fraud and abuse laws apply to Xtant’s business when a customer submits a claim for an item or service that is reimbursed under Medicare,Medicaid or most other federally-funded healthcare programs. The Federal Anti-Kickback Statute prohibits, among other things, persons from knowingly andwillfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of anindividual for, or the purchase, order or recommendation of, items or services for which payment may be made, in whole or in part, under federal health careprograms, such as by Medicare or Medicaid. The concerns that the Anti-Kickback Statute addresses are multiple, but primary among them are, first, that thefederal government pays/reimburses health care providers for the true acquisition cost of goods and services provided to patients served by governmentprograms. The government does not want, for example, health care providers obtaining manufacturer discounts which are not disclosed to the government oncost report forms submitted for reimbursement to the government. The government wants to be the beneficiary of such discounts. Second, for that reason, thegovernment wants transparency in the billing process which discloses such discounts to the government. Third, the government does not want purchasing,prescription or referral decisions for medical devices biased by economics unrelated to the best choices for a patient. The Federal Anti-Kickback Statute is subject to evolving interpretations and has been applied by government enforcement officials to a number ofcommon business arrangements in the medical device industry. Remunerative relationships with physicians in which manufacturers give health careproviders gifts or pay for entertainment, sporting events, trips or other perquisites, may be viewed as an attempt to buy loyalty to the manufacturer’s products.A number of states also have anti-kickback laws that establish similar prohibitions that may apply to items or services reimbursed by government programs aswell as any third-party payors, including commercial insurers. 11 Further, federal legislation, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act(collectively “PPACA”), among other things, clarified the intent requirements of the Federal Anti-Kickback Statute and the federal criminal statutesgoverning healthcare fraud. Specifically, a person or entity can be found to have violated the statutes without actual knowledge of these statutes or specificintent to violate them. In addition, the PPACA amended the Social Security Act to provide that the government may assert that a claim including items orservices resulting from a violation of the Federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the Federal False Claims Act orfederal civil money penalties statute. Recent amendments to the Federal False Claims Act provide that a violation of the Federal Anti-Kickback Statute isalso a violation of the Federal False Claims Act, subjecting healthcare entities to treble damages and mandatory penalties for each false claim or statement. Additionally, the civil Federal False Claims Act prohibits, among other things, knowingly presenting or causing the presentation of a false, fictitiousor fraudulent claim for payment of federal funds, or knowingly making, or causing to be made, a false record or statement material to a false or fraudulentclaim to avoid, decrease or conceal an obligation to pay money to the federal government. The purpose of the Federal False Claims Act is to preventmanufacturers from causing or inducing inappropriate prescriptions leading to an inappropriate government reimbursement. It often comes into play where amanufacturer suggests or assists a health care provider to bill for an off-label, uncovered use. It also can occur when the reimbursement advice given by amanufacturer results in inappropriate reimbursement claims from “upcoding,” miscoding, “stretched” coding, the use of inappropriate modifiers orinappropriate care settings. These behaviors can result in the government paying for products or procedures that should not be reimbursed by the federalgovernment. The manufacturer must be truthful and not misleading in the reimbursement advice it gives to customers. Actions under the Federal False Claims Act may be brought by the Attorney General or as a qui tam action by a private individual in the name of thegovernment. Violations of the Federal False Claims Act can result in very significant monetary penalties and treble damages. The federal government is usingthe Federal False Claims Act, and the accompanying threat of significant liability, in its investigations of healthcare companies throughout the country for awide variety of Medicare billing practices, as well as federal Anti-Kickback Statute violations and certain marketing practices, including off-label promotion,and has obtained multi-million and multi-billion dollar settlements under the Federal False Claims Act in addition to individual criminal convictions underapplicable criminal statutes. Given the significant size of actual and potential settlements, it is expected that the government will continue to devotesubstantial resources to investigating healthcare providers’ and suppliers’ compliance with the healthcare reimbursement rules and fraud and abuse laws. The Federal False Claims Act amendments in 2009 and 2010 expanded the scope of the liability for health care entities generally to potentiallyreach violations of regulatory duties, such as good manufacturing practices. There have been large settlements in the life sciences arena related to FDAregulatory violations for promotional activities and good manufacturing practice. Even in instances where a company may have no actual liability, the Federal False Claims Act private citizen provisions (qui tam) allow the filing ofFederal False Claims Act actions under seal and impose a mandatory duty on the United States Department of Justice to investigate such allegations. Mostprivate citizen actions are declined by the Department of Justice or dismissed by federal courts. However, the investigation costs for a company can besignificant and material even if the allegations are without merit. Federal False Claims Act liability is potentially significant in the health industry because the statute provides for treble damages and mandatoryminimum penalties of $5,500 to $11,000 per false claim or statement. Because of the potential for large monetary exposure, health care companies resolveallegations without admissions of liability for significant and material amounts to avoid the uncertainty of treble damages that may awarded in litigationproceedings. They may be required, however, to enter into corporate integrity agreements with the government, which may impose substantial costs tocompanies to ensure compliance. 12 The Federal Physician Payments Sunshine Act imposes annual reporting requirements on device manufacturers for payments and other transfers ofvalue provided by them, directly or indirectly, to physicians (including physician family members) and teaching hospitals, as well as ownership andinvestment interests held by physicians. A manufacturer’s failure to submit timely, accurately and completely the required information for all payments,transfers of value or ownership or investment interests may result in civil monetary penalties of up to an aggregate of $150,000 per year, and up to anaggregate of $1.0 million per year for “knowing failures.” Manufacturers must submit reports by the 90th day of each calendar year. Certain states alsomandate implementation of commercial compliance programs, impose restrictions on device manufacturer marketing practices and require tracking andreporting of gifts, compensation and other remuneration to healthcare professionals and entities. The shifting commercial compliance environment and theneed to build and maintain robust and expandable systems to comply with different compliance or reporting requirements in multiple jurisdictions increasethe possibility that a healthcare company may fail to comply fully with one or more of these requirements. If a governmental authority were to conclude that Xtant is not in compliance with applicable laws and regulations, Xtant and its officers andemployees could be subject to severe criminal and civil penalties, including, for example, exclusion from participation as a supplier of product tobeneficiaries covered by Medicare, Medicaid and other federal health care programs. Our United States operations are subject to the U.S. Foreign CorruptPractices Act (“FCPA”). We are required to comply with the FCPA, which generally prohibits covered entities and their intermediaries from engaging inbribery or making other prohibited payments to foreign officials for the purpose of obtaining or retaining business or other benefits. In addition, the FCPAimposes accounting standards and requirements on publicly traded United States corporations and their foreign affiliates, which are intended to prevent thediversion of corporate funds to the payment of bribes and other improper payments, and to prevent the establishment of “off books” slush funds from whichsuch improper payments can be made. We also are subject to similar anticorruption legislation implemented in Europe under the Organization for EconomicCo-operation and Development’s Convention on Combating Bribery of Foreign Public Officials in International Business Transactions. Coverage and Reimbursement Xtant’s currently approved products are commonly treated as general supplies utilized in spinal and orthopedic surgery and if covered by third-partypayors, are paid for as part of the surgical procedure. Accordingly, healthcare providers in the United States generally rely on third-party payors, principallyprivate insurers and governmental payors such as Medicare and Medicaid, to cover and reimburse all or part of the cost of a spine surgery in which Xtantproducts are used. Sales volumes and fees for Xtant products will continue to depend in large part on the availability of coverage and reimbursement fromsuch third-party payors. Third-party payors perform analyses on new technologies to determine if they are medically necessary before providing coverage forthem. These third-party payors may still deny reimbursement on covered technologies if they determine that a device used in a procedure was not used inaccordance with the payor’s coverage policy. Particularly in the United States, third-party payors continue to carefully review, and increasingly challenge,the prices charged for procedures and medical products. In the United States, a large percentage of insured individuals receive their medical care through managed care programs, which monitor and oftenrequire pre-approval of the services that a member will receive. Some managed care programs pay their providers on a per capita basis, which puts theproviders at financial risk for the services provided to their patients by paying these providers a predetermined payment per member per month and,consequently, may limit the willingness of these providers to use Xtant products. The overall escalating cost of medical products and services has led to, and will likely continue to lead to, increased pressures on the healthcareindustry to reduce the costs of products and services. Government or private third-party payors cannot be guaranteed to cover and reimburse the proceduresusing Xtant products in whole or in part in the future or that payment rates will be adequate. In addition, it is possible that future legislation, regulation orcoverage and reimbursement policies of third-party payors will adversely affect the demand for Xtant products or the ability to sell them on a profitable basis. Internationally, reimbursement and healthcare payment systems vary substantially from country to country and include single-payor, government-managed systems as well as systems in which private payors and government managed systems exist side-by-side. Xtant’s ability to achieve marketacceptance or significant sales volume in international markets will be dependent in large part on the availability of reimbursement for procedures performedusing company products under the healthcare payment systems in such markets. A number of countries may require Xtant to gather additional clinical databefore recognizing coverage and reimbursement for its products. 13 ISO Certification Xtant is proud to be an International Organization for Standardization (“ISO”) certified organization, which declares our company-wide commitmentto quality. To obtain ISO 13485:2016 certification, an organization must demonstrate its ability to provide medical devices that consistently meet applicablecustomer and regulatory requirements. The primary objective of ISO 13485:2016 is to facilitate harmonized medical device regulatory requirements forquality management systems. All requirements of ISO 13485:2016 are specific to organizations providing medical devices, regardless of the type or size ofthe organization. The certification assures our customers and partners of our commitment to quality, and in the quality of our innovative products andprocesses. Additionally, we believe that our ISO 13485:2016 certification may offer new markets and business opportunities for our products in the globalmarketplace. Employees As of December 31, 2018, Xtant had 166 employees, of whom 75 were in operations, 39 were in sales and marketing, 8 in research and developmentand engineering, 19 in regulatory and quality affairs, and 25 were in administrative functions. In addition, we make use of a varying number of outsourcedservices to manage normal business cycles. None of our employees are covered by a collective bargaining agreement and management considers relationswith employees and service partners to be good. Available Information We make available, free of charge and through our Internet web site, our annual reports on Form 10-K, quarterly reports on Form 10-Q, currentreports on Form 8-K, and any amendments to any such reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, asamended, as soon as reasonably practicable after we electronically file such material with, or furnishes it to, the Securities and Exchange Commission(“SEC”).

The following risk factors describe some of the mostsignificant events, facts or circumstances that could have a material adverse effect upon our business, financial condition, results of operations, ability toimplement our business plan and the market price for our common stock. Many of these events are outside of our control. If any of these risks actually occur,our business, financial condition or results of operations may be materially adversely affected. In such case, the trading price of our common stock coulddecline and investors in our common stock could lose all or part of their investment. Risks Related to Our Outstanding Indebtedness, Need for Additional Financing and Financial Condition We have incurred significant losses, expect to continue to incur losses and may never be profitable. We have a history of operating losses and at December 31, 2018, we had an accumulated deficit of $215.0 million. Our ability to achieveprofitability will be influenced by many factors, including, among others, the level and timing of future revenues and expenditures; development,commercialization and market acceptance of our products; competing technologies and market developments; regulatory requirements and delays; ability toattract and retain key personnel; and pending litigation. As a result, we may continue to incur operating losses for the foreseeable future. These losses willcontinue to have an adverse impact on our stockholders’ equity, and we may never achieve or sustain profitability. We will need additional financing to satisfy our anticipated future liquidity requirements, which financing may not be available on favorable terms at thetime it is needed and which could reduce our operational and strategic flexibility. We have substantial operating expenses associated with the sales and marketing of our products. Although it is difficult for us to predict our futureliquidity requirements, we believe that our cash and cash equivalents balance of approximately $6.8 million, as of December 31, 2018, together with existingcredit availability and $10.0 million in availability under our Second Amended and Restated Credit Facility dated March 29, 2019 will be sufficient to meetour anticipated cash requirements through the end of March 2020. Although we recently increased availability under our Second Amended and RestatedCredit Agreement, we still believe we may require additional funds to fund our future operations and business strategy. Accordingly, there is no assurancethat we will not need or seek additional funding. We may elect to raise additional funds even before we need them if market conditions for raising additionalcapital are favorable. We may seek to raise additional funds through various sources, such as equity and debt financings, additional debt restructurings orrefinancings, or through strategic collaborations and license agreements. We can give no assurances that we will be able to secure additional sources of fundsto support our operations, or if such funds are available to us, that such additional financing will be sufficient to meet our needs or on terms acceptable to us.This is particularly true if economic and market conditions deteriorate. Any failure by us to raise additional funds on terms favorable to us, or at all, couldresult in our inability to pay our expenses as they come due, limit our ability to expand our business operations, and harm our overall business prospects. Ifadequate funds are not otherwise available, we could be required to curtail operations significantly, including reducing our sales and marketing expenseswhich could negatively impact product sales and we could even be required to cease operations, liquidate our assets and possibly seek bankruptcyprotection. To the extent that we raise additional capital through the sale of equity or convertible debt securities or the restructuring or refinancing of our debt,the interests of our current stockholders may be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of ourcurrent stockholders. If we issue preferred stock, it could affect the rights of our stockholders or reduce the value of our common stock. In particular, specificrights granted to future holders of preferred stock may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights,sinking fund provisions, and restrictions on our ability to merge with or sell our assets to a third party. Additional debt financing, if available, may involveagreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expendituresor declaring dividends. Prior to raising additional equity or debt financing, we must obtain the consent of ROS and Royalty Opportunities, the lenders underour Second Amended and Restated Credit Agreement, and no assurance can be provided that ROS and Royalty Opportunities would provide such consent,which could limit our ability to raise additional financing. 15 We have a significant amount of indebtedness. We may not be able to generate enough cash flow from our operations to service our indebtedness, and wemay incur additional indebtedness in the future, which could adversely affect our business, financial condition, and operating results. We have a significant amount of indebtedness, including, as of December 31, 2018, $77.9 million in aggregate principal plus additional accruedinterest outstanding under our credit facility. Our ability to make payments on, and to refinance, our indebtedness, including amounts borrowed under ourcredit facility, and our ability to fund planned capital expenditures, contractual cash obligations, known and unknown liabilities, research and developmentefforts, working capital, any future acquisitions and business combinations, and other general corporate purposes depends on our ability to generate cash inthe future. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory, and other factors, some of which are beyondour control. If we do not generate sufficient cash flow from operations or if future borrowings are not available to us in an amount sufficient to pay ourindebtedness or to fund our liquidity needs, we may be forced to refinance all or a portion of our indebtedness on or before the maturity dates thereof, sellassets, reduce or delay capital expenditures, seek to raise additional capital, or take other similar actions. We may not be able to execute any of these actionson commercially reasonable terms or at all. Our ability to refinance our indebtedness will depend on our financial condition at the time, the restrictions in theinstruments governing our indebtedness, the consent of our lenders, and other factors, including market conditions. Our inability to generate sufficient cashflow to satisfy our debt service obligations, or to refinance or restructure our obligations on commercially reasonable terms or at all, would likely have anadverse effect, which could be material, on our business, financial condition, and operating results. In addition, our significant indebtedness, combined with our other financial obligations and contractual commitments, could have other importantconsequences. For example, it could: ●make us more vulnerable to adverse changes in general U.S. and worldwide economic, industry, and competitive conditions and adverse changes ingovernment regulation; ●limit our flexibility in planning for, or reacting to, changes in our business and our industry; ●restrict our ability to make strategic acquisitions, business combinations or dispositions or to exploit business opportunities; ●place us at a competitive disadvantage compared to our competitors who have less debt; and ●limit our ability to borrow additional amounts or raise financing for working capital, capital expenditures, contractual obligations, research anddevelopment efforts, acquisitions or business combinations, debt service requirements, execution of our business strategy, or other purposes. Any of these factors could materially and adversely affect our business, financial condition, and operating results. In addition, we may incuradditional indebtedness, and if we do, the risks related to our business and our ability to service our indebtedness would increase. A failure to comply with the covenants and other provisions of our Second Amended and Restated Credit Agreement could require the immediaterepayment of our outstanding indebtedness. If we are at any time unable to generate sufficient cash flows from operations to service our indebtedness whenpayment is due, we may be required to attempt to renegotiate the terms of the credit agreement, seek to refinance all or a portion of the indebtedness, orobtain additional financing. There can be no assurance that we will be able to successfully renegotiate such terms, that any such refinancing would bepossible, or that any additional financing could be obtained on terms that are favorable or acceptable to us. 16 The terms of our Second Amended and Restated Credit Agreement could limit our ability to conduct our business, take advantage of businessopportunities and respond to changing business, market, and economic conditions. Our Second Amended and Restated Credit Agreement includes a number of significant financial and operating restrictions. For example, theagreement contains financial covenants that, among other things, require us to maintain a minimum liquidity covenant and a minimum revenue base, each asdefined in the agreement, and contains provisions that restrict our ability, subject to specified exceptions, to, among other things: ●make loans and investments, including acquisitions and transactions with affiliates; ●create liens or other encumbrances on our assets; ●dispose of assets; ●enter into contingent obligations; ●NYSE compliance; ●engage in mergers or consolidations; and ●pay dividends. We may be unable to comply with these covenants, which could result in a default under the agreement. In addition, these provisions may limit ourability to conduct our business, take advantage of business opportunities, and respond to changing business, market, and economic conditions. In addition,they may place us at a competitive disadvantage relative to other companies that may be subject to fewer, if any, restrictions or may otherwise adverselyaffect our business. Transactions that we may view as important opportunities, such as significant acquisitions or business combinations, may be subject tothe consent of the lenders, which consent may be withheld or granted subject to conditions specified at the time that may affect the attractiveness or viabilityof the transaction. Our Credit Facility involves additional risks that may adversely affect our liquidity, results of operations, and financial condition. Availability under the Second Amended and Restated Credit Agreement is based on the amount of our liquidity, financial performance, and salesresults. As a result, our access to credit under the Second Amended and Restated Credit Facility is subject to fluctuations depending on our financial resultsand projected cash balances as of any valuation date. Our inability to borrow additional amounts under the credit facility may adversely affect our liquidity,results of operations, and financial condition. Our outstanding indebtedness under the credit facility will, after March 31, 2020, bear interest at variable rates, which subjects us to interest rate riskand could increase the cost of servicing our indebtedness. The impact of increases in interest rates could be more significant for us than it would be for someother companies because of our indebtedness, thereby affecting our profitability. In the event of a default under our Second Amended and Restated CreditAgreement, the lenders may terminate their commitments to lend additional money under the credit facility and declare all amounts outstanding thereunderto be immediately due and payable. While an event of default is continuing under the Second Amended and Restated Credit Agreement, the lendersthereunder may elect to increase the rates at which interest accrues. Subject to certain exceptions, amounts outstanding under the credit facility are secured bya senior first priority security interest in substantially all existing and after-acquired assets of our company and each borrower. Accordingly, under certaincircumstances, the lenders could seek to enforce security interests in our assets securing our indebtedness under the credit facility, including restricting ouraccess to collections on our accounts receivable. Any acceleration of amounts due under our Second Amended and Restated Credit Agreement or the exerciseby the lenders thereto of their rights under the security documents, would have a material adverse effect on us. 17 We may be unable to meet financial or other covenant requirements in our Second Amended and Restated Credit Agreement, and we may be unable tosuccessfully negotiate waivers to cure any covenant violations. Our Second Amended and Restated Credit Agreement contains representations, warranties, fees, affirmative and negative covenants, including aminimum liquidity covenant and a minimum revenue base covenant, and default provisions. A breach of any of these covenants could result in a defaultunder this agreement. Upon the occurrence of an event of default under the Second Amended and Restated Credit Agreement, the lenders could elect todeclare all amounts outstanding under the credit facility to be immediately due and payable and terminate all commitments to extend further credit. If thelenders accelerate the repayment of borrowings, we may not have sufficient assets to repay our indebtedness. Also, should there be an event of default, orshould we need to obtain waivers following an event of default, we may be subject to higher borrowing costs and/or more restrictive covenants in futureperiods. In addition, to secure the performance of our obligations under the Second Amended and Restated Credit Agreement, we pledged substantially all ofour assets, including our intellectual property, to the lenders. Our failure to comply with the covenants under the Second Amended and Restated CreditAgreement could result in an event of default, the acceleration of our debt and the loss of our assets. We rely on our subsidiaries for funds necessary to meet our financial obligations. We conduct substantially all of our activities through our subsidiaries. We depend on those subsidiaries for dividends and other payments togenerate the funds necessary to meet our financial obligations, including our outstanding indebtedness. The ability of our subsidiaries to make payments tous may be restricted by, among other things, applicable state corporation or similar statutes and other laws and regulations. The earnings from, or otheravailable assets of, our subsidiaries may be insufficient to enable us to pay the outstanding principal or interest due on our outstanding indebtedness whendue. Risks Related to Our Business Many competitive products exist and more will be developed. Our operating results have suffered due to intense competition and we may not be able tosuccessfully compete because we are smaller and have fewer financial resources. The markets for our products are highly competitive and subject to rapid and profound technological change. Our success depends, in part, on ourability to maintain a competitive position in the development of technologies and products for use by our customers. Many of the companies developing ormarketing competitive products enjoy several competitive advantages over us, including greater financial and human resources for product development andsales and marketing; greater name recognition; established relationships with surgeons, hospitals and third-party payors; broader product lines and the abilityto offer rebates or bundle products to offer greater discounts or incentives to gain a competitive advantage; and established sales and marketing anddistribution networks. Our competitors may develop and patent processes or products earlier than us, obtain regulatory clearances or approvals for competingproducts more rapidly than us, develop more effective or less expensive products or technologies that render our technology or products obsolete or non-competitive or acquire technologies and technology licenses complementary to our products or advantageous to our business, which could adversely affectour business and operating results. Not all of our sales and other personnel have non-compete agreements. We also compete with other organizations inrecruiting and retaining qualified sales and management personnel. If our competitors are more successful than us in these matters, we may be unable tocompete successfully against our existing or future competitors. Intense competition adversely affected our operating results during 2018. In addition, ourindustry has been subject to increasing consolidation. Consolidation in our industry not involving our company could result in existing competitorsincreasing their market share through business combinations and result in stronger competitors, which could have a material adverse effect on our business,financial condition, and operating results. We may be unable to compete successfully in an increasingly consolidated industry and cannot predict withcertainty how industry consolidation will affect our competitors or us. 18 If we are unable to continue to develop and market new products and technologies, we may experience a decrease in demand for our products, or ourproducts could become obsolete, and our business and operating results would suffer. Due to lack of funding, our research and development efforts have suffered during the past few years. We may be unable to compete effectively withour competitors unless we can keep up with existing or new products and technologies in the markets in which we compete. If we do not continue tointroduce new products and technologies, or if those products and technologies are not accepted, we may not be successful. Moreover, research anddevelopment efforts require a substantial investment of time and resources before we are adequately able to determine the commercial viability of a newproduct, technology, material, or innovation. Demand for our products also could change in ways we may not anticipate due to evolving customer needs,changing demographics, slow industry growth rates, declines in our markets, the introduction of new products and technologies, evolving surgicalphilosophies, and evolving industry standards, among others. Additionally, our competitors’ new products and technologies may beat our products tomarket, may be more effective or less expensive than our products, or may render our products obsolete. It is also important that we carefully manage ourintroduction of new and enhanced products and technologies. If potential customers delay purchases until new or enhanced products are available, it couldnegatively impact our revenue. Our new products and technologies also could reduce demand for or render our existing products obsolete and thus adverselyaffect sales of our existing products and lead to increased expense for excess and obsolete inventory. We are highly dependent on the availability of human donors; any disruptions could cause our customers to seek alternative providers or technologies. We are highly dependent on our ability to obtain donor cadavers as the raw material for many of our biologics products. The availability ofacceptable donors is relatively limited, and we compete with many other companies for this limited availability. The availability of donors is also impactedby regulatory changes, general public opinion of the donor process and our reputation for our handling of the donor process. In addition, due to seasonalchanges in the mortality rates, some scarce tissues are at times in short supply. Any disruption in the supply of this crucial raw material could have significantconsequences for our revenue, operating results and continued operations. Our inability to attract and retain key personnel could adversely affect our business and results of operations. Our success is highly dependent upon the services of our executives. However, we have experienced a high level of turnover among our executiveteam over the past year, including the departure of our interim CEO and our CFO during the first quarter of 2019. Most of the members of our managementteam have joined the Company in the past year. Currently, our Vice President of Finance, Greg Jensen, is serving as our interim Chief Financial Officer andour principal executive officer as we search for qualified replacements. The loss of Mr. Jensen, or the loss of any of the remaining key members of ourmanagement team, such as our Chief Commercial Officer and Chief Operations Officer, could have a material adverse effect on our future operations. We donot currently maintain key-person life insurance policies insuring the life of any member of our management team. Our future success also depends, in part, upon our ability to retain and motivate key managerial, sales, and technical personnel, as well as our abilityto continue to attract and retain additional highly qualified personnel. We compete for such personnel with other companies, academic institutions,governmental entities, and other organizations. There can be no assurance that we will be successful in retaining our current personnel or in hiring orretaining qualified personnel in the future. Any unanticipated loss or interruption of services of our management team and our key personnel couldsignificantly reduce our ability to meet our strategic objectives due to extended time required for us to find appropriate replacement personnel, if at all,should the need arise. Loss of key personnel or the inability to hire or retain qualified personnel in the future could have a material adverse effect on ourability to operate successfully. 19 We are highly dependent on the continued availability of our facilities and would be harmed if they were unavailable for any prolonged period of time. Any failure in the physical infrastructure of our facilities or services could lead to significant costs and disruptions that could reduce our revenuesand harm our business reputation and financial results. We are highly reliant on our Belgrade, Montana facilities. Any natural or man-made event thatimpacts our ability to utilize these facilities could have a significant impact on our operating results, reputation and ability to continue operations. Theregulatory process for approval of facilities is time-consuming and our ability to rebuild facilities would take a considerable amount of time and expense andcause a significant disruption in service to our customers. Further, the FDA or some other regulatory agency could identify deficiencies in future inspectionsof our facilities or our supplies that could disrupt our business and harm our operating results. This is risk is particularly relevant with respect to the Class 2recall of our Calix Lumbar Spine Implant System initiated in December 2018. We may be subject to product liability litigation that could be expensive, and our insurance coverage may not be adequate in a catastrophic situation. The manufacture and sale of medical devices and biologics expose us to significant risk of product liability claims. We may incur material liabilitiesrelating to product liability claims, including product liability claims arising out of the use of our products. We also could experience a material design ormanufacturing failure in our products, a quality system failure, other safety issues, or heightened regulatory scrutiny that would warrant a recall of some ofour products. This risk is relevant with respect to our Calix Lumbar Spine Implant System recall initiated in December 2018. Product liability lawsuits andclaims, safety alerts and product recalls, regardless of their ultimate outcome, could result in decreased demand for our products, injury to our reputation,significant litigation and other costs, substantial monetary awards to or costly settlements with patients, product recalls, loss of revenue, increased regulatoryscrutiny, and the inability to commercialize new products or product candidates, and otherwise have a material adverse effect on our business and reputationand on our ability to attract and retain customers. We currently carry product liability insurance; however, our insurance coverage may not be adequate, andour business could suffer material adverse consequences due to product liability claims. Litigation may result in financial loss and/or impact our ability to sell our products going forward. We are subject to certain pending litigation and dispute matters. For example, in December 2018, a complaint was filed by RSB Spine, LLC againstus which claims that some of our products, including the Irix-ATM Lumbar Integrated Fusion System and the Irix-CTM Cervical Integrated Fusion System,infringe certain of RSB Spine’s patents. The complaint seeks, among other relief, an injunction against future infringement, unspecified damages forinfringement, and treble damages for willful infringement. Our pending litigation is discussed in Note 9 to our consolidated financial statements. Althoughwe intend to vigorously defend any existing or future litigation or dispute in which we may be involved, there can be no assurance that we will prevail inthese matters. An unfavorable judgment or settlement may result in a financial burden on us. An unfavorable judgment or settlement may also result inrestrictions on our ability to sell certain products and therefore may impact future operating results. Moreover, costs, fees, expenses, settlement amounts,judgments or other liabilities associated with such matters may not be covered by our insurance. We have completed acquisitions and business combinations in the past and may complete them in the future. Acquisitions and business combinations arerisky and may harm our business, reputation, financial condition, and operating results. We have completed acquisitions and business combinations in the past, including the acquisition of X-spine Systems, Inc. in 2015, and maycomplete them in the future. Our ability to complete acquisitions and business combinations will depend, in part, on the availability of suitable candidates atacceptable prices, terms, and conditions; our ability to compete effectively for acquisition candidates; and the availability of capital and personnel tocomplete such acquisitions and run the acquired business effectively. Any acquisition or business combination could impair our business, financialcondition, reputation, and operating results. The benefits of an acquisition or business combination may take more time than expected to develop or integrateinto our operations, and we cannot guarantee that previous or future acquisitions or business combinations will, in fact, produce any benefits. Acquisitionsand or business combinations may involve a number of risks, the occurrence of which could adversely affect our business, reputation, financial condition,and operating results, including: ●diversion of management’s attention; ●disruption to our existing operations and plans; 20 ●inability to effectively manage our expanded operations; ●difficulties or delays in integrating and assimilating information and financial systems, operations, manufacturing processes and products of anacquired business or other business venture or in realizing projected efficiencies, growth prospects, cost savings, and synergies; ●inability to successfully integrate or develop a distribution channel for acquired product lines; ●potential loss of key employees, customers, distributors, or sales representatives of the acquired businesses or adverse effects on existingbusiness relationships with suppliers, customers, distributors, and sales representatives; ●violation of confidentiality and non-compete obligations or agreements by employees of an acquired business; ●adverse impact on overall profitability if our expanded operations do not achieve the financial results projected in our valuation models; ●reallocation of amounts of capital from other operating initiatives and/or an increase in our leverage and debt service requirements to payacquisition purchase prices or other business venture investment costs, which could in turn restrict our ability to access additional capital whenneeded or pursue other important elements of our business strategy; ●infringement by acquired businesses or other business ventures of intellectual property rights of others; ●inaccurate assessment of additional post-acquisition investments, undisclosed, contingent or other liabilities or problems, unanticipated costsassociated with an acquisition, and an inability to recover or manage such liabilities and costs; ●incorrect estimates made in the accounting for acquisitions and incurrence of non-recurring charges; and ●write-off of significant amounts of goodwill or other assets as a result of deterioration in the performance of an acquired business or product line,adverse market conditions, changes in the competitive landscape, changes in laws or regulations that restrict activities of an acquired businessor product line, or as a result of a variety of other circumstances. During the year ended December 31, 2018, we incurred a goodwill impairment of $38.3 million as well as an impairment charge of $9.8 million totradenames, technology, and customer relationships related to the fixation business that we acquired in connection with our 2015 acquisition of X-spineSystems, Inc. In addition, effective internal controls are necessary for us to provide reliable and accurate financial reports and to effectively prevent fraud. Theintegration of acquired businesses may result in our systems and controls becoming increasingly complex and more difficult to manage. We devotesignificant resources and time to comply with the internal control over financial reporting requirements of the Sarbanes-Oxley Act of 2002. However, wecannot be certain that these measures will ensure that we design, implement, and maintain adequate control over our financial processes and reporting in thefuture, especially in the context of acquisitions of other businesses. Any difficulties in the assimilation of acquired businesses into our control system couldharm our operating results or cause us to fail to meet our financial reporting obligations. Also, some acquisitions may require the consent of the lenders underour credit facility. We cannot predict whether such approvals would be forthcoming or the terms on which the lenders would approve such acquisitions.These risks, among others, could be heightened if we complete a large acquisition or other business combination or multiple transactions within a relativelyshort period of time. 21 Our quarterly operating results are subject to substantial fluctuations, and you should not rely on them as an indication of our future results. Our quarterly operating results may vary significantly due to a combination of factors, many of which are beyond our control. These factors include: ●demand for products; ●the level of competition; ●the number, timing, and significance of new products and product introductions and enhancements by us and our competitors; ●our ability to develop, introduce, and market new and enhanced versions of our products on a timely basis; ●the timing of or failure to obtain regulatory clearances or approvals for products; ●changes in pricing policies by us and our competitors; ●changes in the treatment practices of our customers; ●changes in distributor or independent sales representative relationships and sales force size and composition; ●the timing of material expense- or income-generating events and the related recognition of their associated financial impact; ●the number and mix of products sold in the quarter and the geographies in which they are sold; ●the number of selling days; ●the availability and cost of components and materials; ●the timing of orders and shipments; ●ability to obtain reimbursement for our products and the timing of patients’ use of their calendar year medical insurance deductibles; ●work stoppages or strikes in the healthcare industry; ●changes in FDA and foreign governmental regulatory policies, requirements, and enforcement practices; ●changes in accounting standards, policies, estimates, and treatments; ●restructuring, impairment, and other special charges; ●costs associated with our pending litigation; ●variations in cost of sales due to the amount and timing of excess and obsolete inventory charges, commodity prices, and manufacturingvariances; ●income tax fluctuations and changes in tax rules; ●general economic factors; and ●increases of interest rates, which can increase the cost of borrowings under our credit facility, and generally affect the level of economic activity. We believe our quarterly revenue and operating results may vary significantly in the future and period-to-period comparisons of our results ofoperations are not necessarily meaningful and should not be relied upon as indications of future performance. We cannot assure you that our revenue willincrease or be sustained in future periods or that we will be profitable in any future period. Any shortfalls in revenue or earnings from levels expected byindustry analysts could have an immediate and significant adverse effect on the trading price of our common stock in any given period. 22 A significant portion of our product revenue is made through independent distributors and sales agents who we do not control. A significant portion of our product revenue is made through distributors and independent sales agents. Because the independent distributor oftencontrols the customer relationships within its territory (and, in certain countries outside the United States, the regulatory relationship), there is a risk that ifour relationship with the distributor ends, our relationship with the customer will be lost (and, in certain countries outside the United States, that we couldexperience delays in amending or transferring our product registrations). Also, because we do not control the field sales agents of a distributor or independentsales agent, there is a risk we will be unable to ensure that our sales processes, compliance, and other priorities will be consistently communicated andexecuted by the distributor or sales agent. If we fail to maintain relationships with our key distributors and independent sales representatives or fail to ensurethat our distributors and independent sales agent adhere to our sales processes, compliance, and other priorities, this could have an adverse effect on ouroperations. Changes to or turnover within our independent distributor and independent sales agent organization or transitions to direct selling models alsocould adversely affect our business if these transitions are not managed effectively. During 2018, we experienced changes to and turnover within ourdistributor and independent sales organization which had an adverse effect on our business. Further, independent distributors and sales agents of companieswe have acquired may decide not to renew or may decide to seek to terminate, change and/or renegotiate their relationships with us. A loss of a significantnumber of our distributors or agents could have a material adverse effect on our business and results of operations. In addition, our success is partially dependent upon our ability to retain and motivate our distributors, independent sales agencies, and theirrepresentatives to sell our products in certain territories. They may not be successful in implementing our marketing plans. Some of our distributors andindependent sales agencies do not sell our products exclusively and may offer similar products from other orthopedic companies. Our distributors andindependent sales agencies may terminate their contracts with us, may devote insufficient sales efforts to our products, or may focus their sales efforts onother products that produce greater commissions for them, which could have an adverse effect on our operations and operating results. The recent notification of the termination of a consulting agreement effective on March 22, 2019 will likely adversely affect our operating resultsbeginning with the first quarter of 2019. In December 2018, we received notification of the termination of a consulting agreement with an entity that has close relationships with several ofour customers representing approximately 23% of our revenue during the year ended December 31, 2018. As a result of this notification, this agreement willterminate effective March 22, 2019. We anticipate that the termination of this agreement will negatively impact our revenues based on our ability to continueto sell products through our distribution channels to our customers affiliated with this entity. Worldwide economic instability could adversely affect our net sales, financial condition, or results of operations. The health of the global economy, and the credit markets and the financial services industry in particular, affects our business and operating results.If the credit markets are not favorable, we may be unable to raise additional financing when needed or on favorable terms. Our customers may experiencefinancial difficulties or be unable to borrow money to fund their operations which may adversely impact their ability to purchase our products or to pay forour products on a timely basis, if at all. In addition, any economic crisis could also adversely impact our suppliers’ ability to provide us with materials andcomponents, either of which may negatively impact our business. As with our customers and vendors, these economic conditions make it more difficult for usto accurately forecast and plan our future business activities. Further, there are concerns for the overall stability and suitability of the Euro as a singlecurrency, given the economic and political challenges facing individual Eurozone countries and Brexit. Continuing deterioration in the creditworthiness ofthe Eurozone countries, the withdrawal of one or more member countries from the European Union, or the failure of the Euro as a common European currencycould adversely affect our sales, financial condition, or operating results. 23 Although our international business is not substantial, we do operate in some markets outside the United States that are subject to political, economic, andsocial instability and expose us to additional risks. Operations in countries outside of the United States accounted for approximately 5% of our total revenue for our year ended December 31, 2018. Ouroperations outside of the United States are accompanied by certain financial and other risks. Our international sales operations expose us and ourrepresentatives, agents, and distributors to risks inherent in operating in foreign jurisdictions. These risks include: ●the imposition of additional U.S. and foreign governmental controls or regulations on orthopedic implants and biologic products; ●withdrawal from or revision to international trade policies or agreements and the imposition or increases in import and export licensing andother compliance requirements, customs duties and tariffs, import and export quotas and other trade restrictions, license obligations, and othernon-tariff barriers to trade; ●unexpected changes in tariffs, trade barriers and regulatory requirements; ●the imposition of U.S. or international sanctions against a country, company, person, or entity with whom we do business that would restrict orprohibit continued business with that country, company, person, or entity; ●economic instability, including currency risk between the U.S. dollar and foreign currencies, in our target markets; ●economic weakness, including inflation, or political instability in particular foreign economies and markets; ●the imposition of restrictions on the activities of foreign agents, representatives, and distributors; ●scrutiny of foreign tax authorities, which could result in significant fines, penalties, and additional taxes being imposed upon us; ●difficulties in managing and staffing international operations and increases in infrastructure costs including legal, tax, accounting, andinformation technology; ●a shortage of high-quality international salespeople and distributors; ●loss of any key personnel who possess proprietary knowledge or are otherwise important to our success in international markets; ●changes in third-party reimbursement policy that may require some of the patients who receive our products to directly absorb medical costs orthat may necessitate our reducing selling prices for our products; ●unexpected changes in foreign regulatory requirements; ●differing local product preferences and product requirements; ●changes in tariffs and other trade restrictions, particularly related to the exportation of our biologic products; ●difficulties in protecting, enforcing and defending intellectual property rights; ●foreign currency exchange controls that might prevent us from repatriating cash; ●longer payment cycles and difficulties in enforcing agreements and collecting receivables through certain foreign legal systems; ●transportation delays and interruptions; ●national and international conflicts, including foreign policy changes, acts of war or terrorist acts; ●complex data privacy requirements and labor relations laws; and ●exposure to different legal and political standards. 24 In addition, in June 2016, the United Kingdom held a referendum in which voters approved an exit from the European Union, commonly referred toas “Brexit.” In March 2017, the government of the United Kingdom formally gave notice of its intent to withdraw from the European Union. Serving thisnotice began a two-year period for the United Kingdom to negotiate terms for its withdrawal from the European Union and future terms of the UnitedKingdom’s relationship with the European Union, including the terms of trade between the United Kingdom and the European Union. Although it isunknown what those terms will be, it is possible that there will be greater restrictions on the movement of goods and people between the United Kingdom andEuropean Union countries and increased regulatory complexities, which could affect our ability to sell our products in certain European Union countries.Brexit could adversely affect European and worldwide economic and market conditions and could contribute to instability in global financial and foreignexchange markets, including volatility in the value of the British pound and Euro. We do not know to what extent these changes will impact our business.Any of these effects of Brexit, and others that we cannot anticipate, could adversely affect our business, operations and financial results. In addition, otherEuropean countries may seek to conduct referenda with respect to continuing membership with the European Union. At this time, it is not certain what steps,may be taken to facilitate the United Kingdom’s exit from the European Union, which has created significant uncertainty about the future relationshipbetween the United Kingdom and the European Union. This development has had and may continue to have a material adverse effect on global economicconditions and the stability of global financial markets. Given the lack of comparable precedent, it is unclear what implications the withdrawal of the UnitedKingdom from the European Union will have and how such withdrawal could affect, or whether it could have a material adverse effect on, our business,financial condition and operating results. The costs of complying with the requirements of the EU-wide General Data Protection Regulation and the potential liability associated with failure to doso could materially adversely affect our business and results of operations. In May 2018, the EU-wide General Data Protection Regulation (“GDPR”) became effective, replacing the current data protection laws of each EUmember state. The GDPR implemented more stringent operational requirements for personal data, including, for example, expanded disclosures about howpersonal information is to be used, limitations on retention of information, increased requirements pertaining to health data and pseudonymised (i.e., key-coded) data, mandatory data breach notification requirements and higher standards for data controllers to demonstrate that they have obtained valid consentfor certain data processing activities. Any failure or perceived failure by us to comply with privacy or security laws, policies, legal obligations or industrystandards or any security incident that results in the unauthorized release or transfer of personally identifiable information may result in governmentalenforcement actions and investigations including by European Data Protection Authorities, fines and penalties, litigation and/or adverse publicity, and couldcause our customers to lose trust in us, which could have an adverse effect on our reputation and business. Such failures could have a material adverse effecton our operating results and financial condition. If the third parties we work with violate applicable laws, contractual obligations or suffer a security breach,such violations may also put us in breach of our obligations under privacy laws and regulations and/or could in turn have a material adverse effect on ourbusiness. In addition, we have spent and expect to continue to expend significant time, costs and resources to comply with the GDPR. We are dependent on various information technology systems, and failures of, interruptions to, or unauthorized tampering of those systems could have amaterial adverse effect on our business. We rely extensively on information technology (“IT”) systems to conduct business. These systems include, but are not limited to, ordering andmanaging materials from suppliers, converting materials to finished products, shipping products to customers, processing transactions, summarizing andreporting results of operations, complying with regulatory, legal or tax requirements, and providing data security and other processes necessary to manageour business. In addition, we have grown in part through strategic business combinations and acquisitions. As a result of these transactions, we may face risksdue to implementation, modification, or remediation of the IT controls, procedures, and policies at the acquired businesses. We continue to consolidate andintegrate the number of systems we operate, and we plan to continue system roll-outs in the future and to otherwise upgrade and expand our IT systemcapabilities. We may experience difficulties in our business operations, or difficulties in operating our business under these systems, either of which coulddisrupt our operations, including our ability to timely ship and track product orders, project inventory requirements, manage our supply chain, and otherwiseadequately service our customers, and lead to increased costs and other difficulties. In the event we experience significant disruptions as a result of theimplementation or upgrade of new systems or otherwise, we may not be able to fix our systems in an efficient and timely manner. Accordingly, such eventsmay disrupt or reduce the efficiency of our entire operations and have a material adverse effect on our operating results and cash flows. 25 In addition, if our systems are damaged or cease to function properly due to any number of causes, ranging from catastrophic events to poweroutages to security breaches, and our business continuity plans do not effectively compensate timely, we may suffer interruptions in our ability to manageoperations. Increased global cybersecurity vulnerabilities, threats and more sophisticated and targeted cybersecurity attacks pose a risk to the security of oursystems and networks and those of our customers, suppliers and third-party service providers, and the confidentiality, availability and integrity of anyunderlying information and data. We have programs, processes and technologies in place to prevent, detect, contain, respond to and mitigate security relatedthreats and potential incidents. We undertake considerable ongoing improvements to our IT systems in order to minimize vulnerabilities, in accordance withindustry and regulatory standards. Because the techniques used to obtain unauthorized access change frequently and can be difficult to detect, anticipating,identifying or preventing these intrusions or mitigating them if and when they occur, may be challenging. Our IT systems require an ongoing commitment ofsignificant resources to maintain, protect and enhance existing systems and develop new systems to keep pace with continuing changes in informationprocessing technology, evolving systems and regulatory standards. We also outsource certain elements of our IT systems to third parties that, as a result ofthis outsourcing, could have access to certain confidential information and whose systems may also be vulnerable to these types of attacks or disruptions.There can be no assurance that our protective measures or those of these third parties will prevent or detect security breaches that could have a significantimpact on our business, reputation, operating results and financial condition. The failure of these systems to operate or integrate effectively with otherinternal, customer, supplier or third-party service provider systems and to protect the underlying IT system and data integrity, including from cyber-attacks,intrusions or other breaches or unauthorized access of these systems, or any failure by us to remediate any such attacks or breaches, may also result in damageto our reputation or competitiveness, delays in product fulfillment and reduced efficiency of our operations, and could require significant capital investmentsto remediate any such failure, problem or breach, all of which could adversely affect our business, operating results and financial condition. We maintaincyber liability insurance; however, this insurance may not be sufficient to cover the financial, legal, business or reputational losses that may result from aninterruption or breach of our systems. Our inability to maintain effective internal controls could cause investors to lose confidence in our reported financial information. Effective internal controls are necessary for us to provide reliable and accurate financial reports and to effectively prevent fraud. The integration ofcombined or acquired businesses is likely to result in our systems and controls becoming increasingly complex and more difficult to manage. We devotesignificant resources and time to comply with the internal control over financial reporting requirements of the Sarbanes-Oxley Act of 2002. However, wecannot be certain that these measures will ensure that we design, implement, and maintain adequate control over our financial processes and reporting in thefuture, especially in light of anticipated changes in accounting standards and in the context of acquisitions of other businesses. If we fail to maintain the adequacy of our internal control over financial reporting or our disclosure controls and procedures, we could be subjectedto regulatory scrutiny, civil or criminal penalties or shareholder litigation, the defense of any of which could cause the diversion of management’s attentionand resources, we could incur significant legal and other expenses, and we could be required to pay damages to settle such actions if any such actions werenot resolved in our favor. Continued or future failure to maintain adequate internal control over financial reporting could also result in financial statementsthat do not accurately reflect our financial condition or results of operations. There can be no assurance that we will not identify any significant deficienciesor material weaknesses that will impair our ability to report our financial condition and results of operations accurately or on a timely basis. Inferior internalcontrols could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of ourordinary shares and our access to capital. 26 Changes in accounting standards, policies, or assumptions utilized in determining accounting estimates could adversely affect our financial statements,including our operating results and financial condition. In preparing our consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”), we must makedecisions that impact our results of operations and/or financial condition. Such decisions include the selection of the appropriate accounting principles to beapplied and the assumptions on which to base accounting estimates. In reaching such decisions, we apply judgments based on our understanding andanalysis of the relevant circumstances, historical experience, and actuarial valuations, as appropriate. As a result, actual amounts could differ from thoseestimated at the time our consolidated financial statements are prepared. Our critical accounting estimates are described later in this report under Part II. Item7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. In addition, various authoritative accounting or regulatoryentities, including the Financial Accounting Standards Board (“FASB”), Public Company Accounting Oversight Board, and the SEC may amend, expand,and/or eliminate the financial accounting or reporting standards that govern the preparation of our consolidated financial statements or could reverse theirprevious interpretations or positions on how various financial accounting and/or reporting standards should be applied. For example, recently, the FASBissued Accounting Standards Update (“ASU”) No. 2016-02, Leases, that amend the accounting standards and related disclosure requirements related to leaseaccounting. We disclose the impact of accounting pronouncements that have been issued but not yet adopted within our annual and quarterly reports onForm 10-K and Form 10-Q, respectively. However, we do not provide an assessment of proposed accounting pronouncements, as such proposals are subject tochange through the exposure process and therefore, we cannot meaningfully assess their effects on our consolidated financial statements. Future changes toaccounting standards could modify the accounting policies and procedures that are currently utilized in the preparation of our consolidated financialstatements. Such changes may be difficult to predict and implement and could materially, or otherwise, impact how we prepare and report our consolidatedfinancial statements, results of operations, and financial condition. Our ability to use our net operating loss carry-forwards and other tax attributes to offset future taxable income is limited. Section 382 of the Internal Revenue Code of 1986, as amended (“Code”), imposes restrictions on the use of a corporation’s net operating losses, aswell as other tax attributes including capital loss carryforwards and other losses and credits, after an “ownership change” occurs. A Section 382 “ownershipchange” occurs if one or more stockholders or groups of stockholders who own at least 5% of our stock (including certain “public groups” deemed created forSection 382 purposes) increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period.We believe that we experienced an ownership change within the meaning of Section 382 upon the conversion of our prior convertible notes in early 2018that could result in significant limitations under Sections 382 on the use of our net operating losses and other tax attributes. However, Section 382 of theCode is an extremely complex provision with respect to which there are many uncertainties, and we have not requested an opinion of a law firm oraccounting firm to confirm our analysis of the ownership change limitations related to the net operating losses generated by the Company. Therefore, wehave not established whether the IRS would agree with our analysis regarding the application of Section 382 of the Code. When an “ownership change” occurs, Section 382 imposes an annual limit on the amount of pre-change net operating losses and other tax attributeswe can use to reduce our taxable income generally equal to the product of the total value of our outstanding equity immediately prior to the “ownershipchange” (subject to certain adjustments) multiplied by the applicable federal long-term tax-exempt interest rate for the month of the “ownership change.” Losses arising in taxable years beginning after December 31, 2017 are limited in the amount of taxable income they can offset but carry forwardindefinitely. Net operating losses incurred in taxable years ending on or before December 31, 2017 generally may be carried forward for up to 20 years tooffset future taxable income but are subject to the Section 382 limitations for losses incurred prior to an ownership change date. Any Section 382 annuallimitation may effectively provide a cap on the cumulative amount of pre-ownership change losses that may be utilized during a carryforward period. Suchpre-ownership change losses in excess of the cap may be lost and could cause a net increase in our United States federal income tax liability in the future,with United States federal income taxes to be paid earlier than they otherwise would be paid if such limitations were not in effect. Further, for financialreporting purposes the amount or value of these deferred tax assets may be reduced as a result of the Section 382 limitation. Such reduction could negativelyimpact the book value of our common stock and could result in an incremental U.S. income tax expense for the Company. 27 In addition, the Tax Cuts and Jobs Act limits the deduction for net operating loss carryforwards to 80 percent of taxable income for losses arising intaxable years beginning after December 31, 2017. Net operating losses subject to these limitations may be carried forward indefinitely. Our ability to deduct interest is limited. Under the Tax Cuts and Jobs Act, our ability to deduct interest on indebtedness properly allocable to our trade or business (which excludesinvestment interest) will be limited to an amount equal to the sum of (i) our business interest income during the taxable year and (ii) 30% of our adjustedtaxable income for such taxable year. Disallowed interest deductions will be carried forward indefinitely and treated as business interest paid or accrued inthe succeeding taxable year. In addition, the interest paid or incurred with respect to our prior convertible notes is not deductible. Risks Related to Governmental Regulation Our business is subject to extensive regulation, including requirements for regulatory clearances or approvals prior to commercial distribution of ourproducts. If we fail to maintain regulatory clearances and approvals, or are unable to obtain, or experience significant delays in obtaining, FDAclearances or approvals for our future products or product enhancements, our ability to commercially distribute and market these products could suffer. Our medical device products and operations are subject to extensive regulation by the FDA and various other federal, state and foreigngovernmental authorities. Government regulation of medical devices is meant to assure their safety and effectiveness, and includes regulation of, amongother things: ●design, development and manufacturing; ●testing, labeling, packaging, content and language of instructions for use, and storage; ●clinical trials; ●product safety; ●premarket clearance and approval; ●marketing, sales and distribution (including making product claims); ●advertising and promotion; ●product modifications; ●recordkeeping procedures; ●reports of corrections, removals, enhancements, recalls and field corrective actions; ●post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to recur, could lead to death orserious injury; ●complying with the federal law and regulations requiring Unique Device Identifiers (UDI) on devices and their labeling and also requiring thesubmission of certain information about each device to FDA’s Global Unique Device Identification Database (GUDID); and ●product import and export 28 Before a new medical device, or a new use of, or claim for, an existing product can be marketed in the United States, it must first receive eitherpremarket clearance under Section 510(k) of the U.S. Federal Food, Drug, and Cosmetic Act (“FDCA”), a de novo classification or a Premarket Approval(“PMA”), from the FDA, unless an exemption applies. The process of obtaining regulatory clearances or approvals to market a medical device can be costlyand time-consuming, and we may not be able to obtain these clearances or approvals on a timely basis, if at all. Most of our currently commercialized products have received premarket clearances under Section 510(k) of the FDCA. In the future, the FDA maydetermine that our products will require the more costly, lengthy and uncertain de novo or PMA processes. If the FDA requires us to go through a lengthier,more rigorous examination for future products or modifications to existing products than we had expected, our product introductions or modifications couldbe delayed or canceled, which could cause our revenue to decline. Although we do not currently market any devices under PMA and have not gone throughthe de novo classification for marketing authorization, we cannot assure you that the FDA will not demand that we obtain a PMA or de novo classificationprior to marketing or that we will be able to obtain 510(k) clearances with respect to future products. The FDA can delay, limit or deny clearance or approval of a device for many reasons, including: ●we may not be able to demonstrate to the FDA’s satisfaction that our products meet the definition of “substantial equivalence” for a 510(k) ormeet the standard for the FDA to grant a petition for de novo classification; ●we may not be able to demonstrate to the FDA’s satisfaction that our products are safe and effective for their intended uses; ●the data from our pre-clinical studies (bench and/or animal) and clinical trials may be insufficient to support clearance or approval in general orfor specific, commercially desirable indications, where required; ●the manufacturing process or facilities we use may not meet applicable requirements; and ●changes in FDA clearance or approval policies or the adoption of new regulations may require additional data. In addition, even if we do obtain clearance or approval, the FDA may not approve or clear these products for the indications that are necessary ordesirable for successful commercialization. Any delay in, or failure to receive or maintain, clearances or approvals for our products under development couldprevent us from generating revenue from these products or achieving profitability. We are subject, directly and indirectly, to federal and state healthcare fraud and abuse laws, false claims laws, and physician payment transparency laws.Failure to comply with these laws may subject us to substantial penalties. We are subject to federal and state healthcare laws and regulations pertaining to fraud and abuse, and physician payment transparency, includingfalse claims laws, anti-kickback laws and physician self-referral laws. Many states such as Massachusetts, Connecticut, Nevada and Vermont require differenttypes of compliance such as having a code of conduct, as well as reporting remuneration paid to health care professionals or entities in a position to influenceprescribing behavior. Violations of these federal and state laws can result in criminal and/or civil punishment, including fines, imprisonment and, in theUnited States, exclusion from participation in government healthcare programs. Greater scrutiny of marketing practices in our industry has resulted innumerous government investigations by various government authorities and this industry-wide enforcement activity is expected to continue. If agovernmental authority were to determine that we do not comply with these laws and regulations, we and our directors, officers and employees could besubject to criminal and civil penalties, including exclusion from participation in U.S. federal healthcare reimbursement programs. 29 Many of these healthcare laws inevitably influence company standards of conduct. Other laws tie into these standards as well, such as compliancewith the advertising and promotion regulations under the FDCA, the Federal Anti-Kickback Statute, the Federal False Claims Act, the Federal PhysicianPayments Sunshine Act and other laws. We use many distributors and independent sales representatives in certain territories and thus rely upon theircompliance with applicable laws and regulations, such as with the advertising and promotion regulations or similar laws under countries located outside theUnited States and other applicable federal, state or international laws. These laws include: ●the Federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering orpaying remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual for, or the purchase, order orrecommendation of, any good or service for which payment may be made under federal healthcare programs, such as the Medicare and Medicaidprograms. A person or entity does not need to have actual knowledge of the Federal Anti-Kickback Statute or specific intent to violate it to havecommitted a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the FederalAnti-Kickback Statute constitutes a false or fraudulent claim for purposes of the Federal False Claims Act; this may constrain our marketingpractices and those of our independent sales agencies, educational programs, pricing, bundling and rebate policies, grants for physician-initiated trials and continuing medical education, and other remunerative relationships with healthcare providers; ●federal false claims laws (such as the Federal False Claims Act) which prohibit, among other things, individuals or entities from knowinglypresenting, or causing to be presented, claims for payment from Medicare, Medicaid or other federal third-party payors that are false orfraudulent; this may impact the reimbursement advice we give to our customers as it cannot be inaccurate and must relate to on-label uses of ourproducts; ●federal criminal laws that prohibit executing a scheme to defraud any federal healthcare benefit program or making false statements relating tohealthcare matters; ● the Federal Physician Payments Sunshine Act, which requires manufacturers of drugs, devices, biologics and medical supplies for whichpayment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to theCenters for Medicare & Medicaid Services (“CMS”), information related to payments or other “transfers of value” made to physicians (definedto include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, and requires applicable manufacturers and grouppurchasing organizations to report annually to CMS ownership and investment interests held by the physicians described above and theirimmediate family members and payments or other “transfers of value” to such physician owners. Effective January 2022, we will also berequired to collect and report information on payments or transfers of value to physician assistants, nurse practitioners, clinical nurse specialists,certified registered nurse anesthetists, and certified nurse-midwives; ●analogous state and foreign law equivalents of each of the above federal laws, such as the Anti-Kickback Statue and the Federal False ClaimsAct which may apply to items or services reimbursed by any third-party payor, including commercial insurers; state laws that require devicecompanies to comply with the industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federalgovernment or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state laws that requiredevice manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers ormarketing expenditures; and state laws governing the privacy and security of health information in certain circumstances, many of which differfrom each other in significant ways and may not have the same effect, thus complicating compliance efforts; and ●the Federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), and its implementing regulations, which created federalcriminal laws that prohibit executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcarematters and which also imposes certain regulatory and contractual requirements regarding the privacy, security and transmission of individuallyidentifiable health information. 30 Certain of these laws have “safe harbors” which if met will protect certain arrangements from liability. For example, the Anti-Kickback Statuteallows for payments that would technically fall under the definition of “remuneration” and be illegal, are allowed because they meet a safe harbor establishedby the Office of Inspector General (“OIG”) of the U.S. Department of Health and Human Services. These safe harbors include, for example, the “Discount” safeharbor which allows companies to provide discounts to their customers in many forms (such as rebates, volume discounts, etc.) as long as they meet therequirements of the safe harbor. Certain safe harbors under the Anti-Kickback Statute may also apply to consulting and other arrangements for personalservices which may apply to relationships we have with physician consultants. These safe harbors are technical in nature and failure to meet any element of asafe harbor will cause an arrangement to lose safe harbor protection. Therefore, no assurances can be given that any of our arrangements or relationships willmeet an otherwise applicable safe harbor. Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available under such laws, it is possible thatsome of our business activities, including our relationships with customers, physicians and other healthcare providers, some of whom have ownershipinterests in the Company and recommend and/or use our products, could be subject to challenge under one or more of such laws. We are also exposed to therisk that our employees, independent contractors, principal investigators, consultants, vendors, and distributors may engage in fraudulent or other illegalactivity. Misconduct by these parties could include, among other infractions or violations, intentional, reckless and/or negligent conduct or unauthorizedactivity that violates FDA regulations, manufacturing standards, federal and state healthcare fraud and abuse laws and regulations, laws that require the true,complete and accurate reporting of financial information or data or other commercial or regulatory laws or requirements. It is not always possible to identifyand deter misconduct by our employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective incontrolling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failureto be in compliance with such laws or regulations. There is also an increasing trend toward more criminal prosecutions and compliance enforcement activities for noncompliance with the HIPAA aswell as for data breaches involving protected health information (PHI). In the ordinary course of our business, we may receive PHI. If we are unable to complywith HIPAA or experience a data breach involving PHI, we could be subject to criminal and civil sanctions. If our operations are found to violate any of the laws described above or any other laws and regulations that apply to us, we may be subject topenalties, including civil and criminal penalties, damages, fines, the curtailment or restructuring of our operations, the exclusion from participation in federaland state healthcare programs and imprisonment, any of which could adversely affect our ability to market our products and materially adversely affect ourbusiness, results of operations and financial condition. Any action against us for violation of these laws, even if we successfully defend against it, could causeus to incur significant legal expenses and divert our management’s attention from the operation of our business. U.S. governmental regulation could restrict the use of our tissue products or our procurement of tissue. In the United States, the procurement and transplantation of allograft bone tissue is subject to federal law pursuant to the National Organ TransplantAct (“NOTA”), a criminal statute which prohibits the purchase and sale of human organs used in human transplantation, including bone and related tissue, for“valuable consideration.” NOTA permits reasonable payments associated with the removal, transportation, processing, preservation, quality control,implantation and storage of human bone tissue. We provide services in all of these areas in the United States, with the exception of removal and implantation,and receive payments for all such services. We make payments to certain of our clients and tissue banks for their services related to recovering allograft bonetissue on our behalf. If NOTA is interpreted or enforced in a manner which prevents us from receiving payment for services we render, or which prevents usfrom paying tissue banks or certain of our clients for the services they render for us, our business could be materially and adversely affected. We are engaged through our marketing employees, independent sales agents and sales representatives in ongoing efforts designed to educate themedical community as to the benefits of our products, and we intend to continue our educational activities. Although we believe that NOTA permitspayments in connection with these educational efforts as reasonable payments associated with the processing, transportation and implantation of ourproducts, payments in connection with such education efforts are not exempt from NOTA’s restrictions and our inability to make such payments inconnection with our education efforts may prevent us from paying our sales representatives for their education efforts and could adversely affect our businessand prospects. No federal agency or court has determined whether NOTA is, or will be, applicable to every allograft bone tissue-based material which ourprocessing technologies may generate. Assuming that NOTA applies to our processing of allograft bone tissue, we believe that we comply with NOTA, butthere can be no assurance that more restrictive interpretations of, or amendments to, NOTA will not be adopted in the future which would call into questionone or more aspects of our method of operations. 31 Outside of the United States, our medical devices must comply with the laws and regulations of the foreign countries in which they are marketed, andcompliance may be costly and time-consuming. Failure to obtain and maintain regulatory approvals in jurisdictions outside the United States will preventus from marketing our products in such jurisdictions. We currently market, and intend to continue to market, our products outside the United States. To market and sell our product in countries outsidethe United States, we must seek and obtain regulatory approvals, certifications or registrations and comply with the laws and regulations of those countries.These laws and regulations, including the requirements for approvals, certifications or registrations and the time required for regulatory review, vary fromcountry to country. Obtaining and maintaining foreign regulatory approvals, certifications or registrations are expensive, and we cannot be certain that wewill receive regulatory approvals, certifications or registrations in any foreign country in which we plan to market our products. The regulatory approvalprocess outside the United States may include all of the risks associated with obtaining FDA clearance or approval in addition to other risks. In order to market our products in the Member States of the European Economic Area (“EEA”), our devices are required to comply with the essentialrequirements of the EU Medical Devices Directives (Council Directive 93/42/EEC of 14 June 1993 concerning medical devices, as amended, and CouncilDirective 90/385/EEC of 20 June 2009 relating to active implantable medical devices, as amended). On April 5, 2017 the EU adopted MDR 2017/745, thenew Medical Devices Regulation, replacing the two existing directives, the Medical Devices Directive and the Active Implantable Medical DevicesDirective. The new regulation will enter into force after a three-year transition period ending in spring 2020. This means that the market access framework forall member countries of the European single market (28 EU member states including the UK, the members of the EEA – Iceland, Lichtenstein and Norway,and through bilateral treaties Switzerland) will change significantly. The key changes that are expected include stricter control, transparency, andenforcement, the strengthening of post market surveillance requirements, and the possibility that the classification of some of our products will change,requiring more rigorous clinical testing and data. Compliance with these requirements entitles us to affix the CE conformity mark to our medical devices, without which they cannot becommercialized in the EEA. In order to demonstrate compliance with the essential requirements and obtain the right to affix the CE conformity mark we mustundergo a conformity assessment procedure, which varies according to the type of medical device and its classification. Except for low risk medical devices(Class I), where the manufacturer can issue an EC Declaration of Conformity based on a self-assessment of the conformity of its products with the essentialrequirements of the Medical Devices Directives, a conformity assessment procedure requires the intervention of a “Notified Body”, which is an organizationaccredited by a Member State of the EEA to conduct conformity assessments. The Notified Body would typically audit and examine the quality system forthe manufacture, design and final inspection of our devices before issuing a certification demonstrating compliance with the essential requirements. Based onthis certification we can draw up an EC Declaration of Conformity, which allows us to affix the CE mark to our products. We may not obtain regulatory approvals or certifications outside the United States on a timely basis, if at all. Clearance or approval by the FDA doesnot ensure approval or certification by regulatory authorities or Notified Bodies in other countries, and approval or certification by one foreign regulatoryauthority or Notified Body does not ensure approval by regulatory authorities in other countries or by the FDA. We may be required to perform additionalpre-clinical or clinical studies even if FDA clearance or approval, or the right to bear the CE mark, has been obtained. If we fail to obtain or maintainregulatory approvals, certifications or registrations in any foreign country in which we plan to market our products, our business, financial condition andoperating results could be adversely affected. 32 In the EEA we must comply with the EU Medical Device Vigilance System, the purpose of which is to improve the protection of health and safety ofpatients, users and others by reducing the likelihood of reoccurrence of incidents related to the use of a medical device. Under this system, incidents must bereported to the competent authorities of the Member States of the EEA. An incident is defined as any malfunction or deterioration in the characteristics and/orperformance of a device, as well as any inadequacy in the labeling or the instructions for use which, directly or indirectly, might lead to or might have led tothe death of a patient or user or of other persons or to a serious deterioration in their state of health. Incidents are evaluated by the EEA competent authoritiesto whom they have been reported, and where appropriate, information is disseminated between them in the form of National Competent Authority Reports(“NCARs”). The Medical Device Vigilance System is further intended to facilitate a direct, early and harmonized implementation of Field Safety CorrectiveActions (“FSCAs”) across the Member States of the EEA where the device is in use. An FSCA is an action taken by a manufacturer to reduce a risk of death orserious deterioration in the state of health associated with the use of a medical device that is already placed on the market. An FSCA may include the recall,modification, exchange, destruction or retrofitting of the device. FSCAs must be communicated by the manufacturer or its legal representative to itscustomers and/or to the end users of the device through Field Safety Notices. Further, the advertising and promotion of our products is subject to EEA Member States Medical Device related laws including 2017/745, the newMedical Device Regulation, or the 2006/114/EC concerning misleading and comparative advertising, as amended, or Directive 2005/29/EC on unfaircommercial practices, as amended, as well as other EEA Member State legislation governing the advertising and promotion of medical devices. These lawsmay limit or restrict the advertising and promotion of our products to the general public and may impose limitations on our promotional activities withhealthcare professionals. Our failure to comply with all these laws and requirements may harm our business and operating results. We may also be required to perform post market clinical follow up studies to periodically evaluate the safety and performance of previouslyapproved products. The results of these studies may cause us to lose our approvals, to market the product or require us to modify our products to addressdeficiencies in order to preserve our approvals to market the product. In March 2019, our Notified Body informed us that we are at risk of losing our CE markon several products for failing to comply with post market clinical follow up requirements. We are working with our Notified Body to remediate thisnonconformance. There can be no assurance that we will be able to remediate this matter on a timeline that is satisfactory to the Notified Body. If this riskwere to materialize, we may be required to remove the effected products from the EU market countries until remediation is complete. Modifications to our products may require new regulatory clearances or approvals or may require us to recall or cease marketing our products untilclearances or approvals are obtained. Any modification to a 510(k)-cleared device that could significantly affect its safety or effectiveness, including significant changes to a device’sdesign, materials, chemical composition, energy source, or manufacturing process, or that would constitute a major change in its intended use, may require anew 510(k) clearance, a de novo classification, or possibly a PMA. Modifications to our products that were implemented without obtaining clearance orapproval and for which FDA subsequently concludes that clearance or approval was required, may require us to recall or cease marketing the modifieddevices until clearance or approval is obtained. The FDA requires device manufacturers to initially make and document a determination of whether or not amodification requires a new approval, supplement or clearance. To do that, a manufacturer must determine if a change/modification to labeling of the deviceis a “major” change to the intended use statement (previously cleared by the FDA) or if a physical change/modification to the device itself “couldsignificantly affect safety or effectiveness.” If the labeling change is major and/or the physical change significantly affects safety and effectiveness, themanufacturer must file for an additional 510(k) clearance, de novo classification, or PMA for those changes before the modified device can be lawfullymarketed. If the company concludes in its own self-determination that the changes do not meet either of the thresholds of “major “or “significantly affects,” itmay simply document those changes by way of an internal letter-to-file as part of the manufacturer’s quality system recording keeping. However, the FDA canreview a manufacturer’s decision and may disagree. The FDA will normally review a decision made by a manufacturer in a letter-to-file during a routine plantinspection, which FDA targets to conduct every two years for high-risk (Class III) device manufacturers and certain low and moderate risk (Class I and II)device manufacturers. In such a review the FDA may determine that a new clearance or approval was required before the device was put into commercialdistribution. 33 We have made modifications to our products in the past that we concluded did not require a new clearance or approval, and we may make additionalmodifications in the future that we believe do not or will not require additional clearances or approvals. No assurance can be given that the FDA would agreewith any of our decisions not to seek 510(k) clearance, de novo classification, or PMA approval. The issue of whether a product modification requiresclearance or approval, as opposed to a “letter-to-file” documenting the change, is not always clear and companies rely on FDA guidance to assist in makingsuch decisions. Up until recently, companies looked to a 1997 guidance document from FDA regarding when a change to a cleared device required a new510(k) clearance. FDA and manufacturers were very familiar with this guidance document. The FDA released new guidance, in October 2017, that supersededthe 1997 guidance. The new guidance is more burdensome in terms of assessing and documenting whether a new 510(k) should be submitted. If the FDA requires us to cease marketing and recall a modified device until we obtain a new 510(k) clearance, de novo classification, or PMA, ourbusiness, financial condition, operating results and future growth prospects could be materially and adversely affected. Further, our products could be subjectto recall if the FDA determines, for any reason, that our products are not safe or effective. Any recall or FDA requirement that we seek additional approvals orclearances could result in significant delays, fines, increased costs associated with modification of a product, loss of revenue and potential operatingrestrictions imposed by the FDA. Obtaining clearances and approvals can be a time-consuming process, and delays in obtaining required future clearances orapprovals would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our future growth. Clinical trials can be long, expensive and ultimately uncertain, which could jeopardize our ability to obtain regulatory approval and market our productsor affect our ability to make claims for our products that are necessary or desirable for commercialization. Clinical trials are generally required to support a de novo or PMA application and are sometimes required for 510(k) clearance. Such trials generallyrequire an investigational device exemption application, or IDE, approved in advance by the FDA for a specified number of patients and study sites, unlessthe product is deemed a nonsignificant risk device, or another exemption applies. Clinical trials are subject to extensive monitoring, recordkeeping andreporting requirements. All clinical trials, including IDE studies and nonsignificant risk device studies, must be conducted under the oversight of aninstitutional review board (“IRB”) for the relevant clinical trial sites and must comply with FDA regulations, including but not limited to those relating togood clinical practices. To conduct a clinical trial, we also are required to obtain the patients’ informed consent in a form and substance that complies withboth FDA requirements and state and federal privacy and human subject protection regulations, unless an exemption applies. We, the FDA or the IRB couldsuspend a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits. In addition, thecommencement or completion of any clinical trial may be delayed or halted for numerous reasons, including, but not limited to patients not enrolling inclinical trials at the rate we expect, patients experiencing adverse side effects, third-party contractors failing to perform in accordance with our anticipatedschedule or consistent with good clinical practices, negative interim trial results, or our inability to obtain sufficient quantities of raw materials to produceour products. Clinical trials often take several years to execute. The outcome of any trial is uncertain and may have a significant impact on the success of ourcurrent and future products and future profits. Our development costs may increase if we have material delays in clinical trials or if we need to perform moreor larger clinical trials than planned. If this occurs, our financial results and the commercial prospects for our products may be harmed. Even if a trial iscompleted, the results of clinical testing may not adequately demonstrate the safety and effectiveness of the device or may otherwise not be sufficient toobtain FDA approval or clearance to market the product in the United States. Moreover, success in pre-clinical studies and early clinical trials does not ensurethat later clinical trials will be successful, and we cannot be sure that the results of the later trials will replicate those of earlier or prior trials. It is also possiblethat subjects enrolled in our clinical trials will experience adverse side effects that are not an anticipated part of the product’s safety profile and, if so, thesefindings may result in lower market acceptance, which could have a material and adverse effect on our business, results of operations and financial condition. 34 Our manufacturing operations are required to comply with the FDA’s and other governmental authorities’ laws and regulations regarding themanufacture and production of medical devices, which is costly and could subject us to enforcement action. We and certain of our third-party manufacturers and suppliers are required to comply with the FDA’s current Good Manufacturing Practices(“cGMP”) requirements and Quality System Regulations (“QSR”), which cover, among other things, the methods of documentation of the design, testing,production, control, quality assurance, labeling, packaging, sterilization, storage and shipping of our products. We and certain of our suppliers also aresubject to the regulations of foreign jurisdictions regarding the manufacturing process for our products marketed outside of the United States. The FDAenforces the QSR through periodic announced (routine) and unannounced (“for cause” or directed) inspections of manufacturing facilities. The failure by usor one of our third-party manufacturers or suppliers to comply with applicable statutes and regulations administered by the FDA and other regulatory bodies,or the failure to timely and adequately respond to any adverse inspectional observations or product safety issues, could result in, among other things, any ofthe following enforcement actions: ●untitled letters, warning letters, fines, injunctions, consent decrees, disgorgement of profits, criminal and civil penalties; ●customer notifications or repair, replacement, refunds, recall, detention or seizure of our products; ●operating restrictions or partial suspension or total shutdown of production; ●refusing or delaying our requests for clearance (510(k)), de novo classification, or approval (PMA) of new products or modified products; ●withdrawing 510(k) clearances, de novo classifications, or PMAs that have already been granted; ●refusal to grant export certificates for our products; or ●criminal prosecution. Any of these actions could impair our ability to produce our products in a cost-effective and timely manner in order to meet our customers’ demands.We also may be required to bear other costs or take other actions that may have a negative impact on our future revenue and our ability to generate profits.Furthermore, our key component suppliers may not currently be or may not continue to be in compliance with all applicable regulatory requirements, whichcould result in our failure to produce our products on a timely basis and in the required quantities, if at all. Even if our medical device products are cleared or approved by regulatory authorities, if we or our suppliers fail to comply with ongoing FDA or otherforeign regulatory authority requirements, or if we experience unanticipated problems with our products, these products could be subject to restrictions orwithdrawal from the market. Any product that we market, will be subject to continued regulatory review, oversight and periodic inspections by the FDA and other domestic andforeign regulatory bodies. Such oversight will cover, among other things, the product’s design and manufacturing processes, the company’s quality systemand compliance with reporting requirements, the company’s compliance with post-approval clinical data requirements, and the company’s promotionalactivities related to its products. Even if regulatory clearance or approval of a product is granted, such clearance or approval may be subject to limitations on the intended uses forwhich the product may be marketed and reduce our potential to successfully commercialize the product and generate revenue from the product. If the FDAdetermines that our promotional materials, labeling, training or other marketing or educational activities constitute promotion of an unapproved use, it couldrequest that we cease or modify our training or promotional materials or subject us to regulatory enforcement actions. It is also possible that other federal,state or foreign enforcement authorities might take action if they consider our training or other promotional materials to constitute promotion of anunapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In addition, we may be required to conduct costly post-market testing and surveillance to monitor the safety or effectiveness of our products. Laterdiscovery of previously unknown problems with our products, including unanticipated adverse events or adverse events of unanticipated severity orfrequency, manufacturing problems, or failure to comply with regulatory requirements such as QSR, may result in, among other things, changes to labeling,restrictions on such products or manufacturing processes, product corrections, removal of the products from the market, voluntary or mandatory recalls, arequirement to repair, replace or refund the cost of any medical device we manufacture or distribute, fines, withdrawal of regulatory clearance or approvals,delays in or refusals of new 510(k)s, de novo or PMA applications, untitled letters, warning letters, refusal to grant export certificates for our products, productseizures, injunctions or the imposition of civil or criminal penalties which would adversely affect our business, operating results and prospects. 35 The use, misuse or off-label use of our products may harm our image in the marketplace or result in injuries that lead to product liability suits, which couldbe costly to our business or result in FDA sanctions if we are deemed to have engaged in improper promotion of our products. Our products currently marketed in the United States have been cleared by the FDA’s 510(k) process for use under specific circumstances. Ourpromotional materials and training methods must comply with FDA and other applicable laws and regulations, including the prohibition on the promotion ofa medical device for a use that has not been cleared or approved by the FDA. We believe that the specific surgical procedures for which our products aremarketed fall within the general intended use of the surgical applications that have been cleared by the FDA. However, the FDA could disagree and require usto stop promoting our products for those specific indications/procedures until we obtain FDA clearance or approval for them. Use of a device outside of itscleared or approved indication is known as “off-label” use. We cannot prevent a surgeon from using our products or procedure for off-label use, as the FDAdoes not restrict or regulate a physician’s choice of treatment within the practice of medicine. However, if the FDA determines that our promotional activities,reimbursement advice or training of sales representatives or physicians constitute promotion of an off-label use, the FDA could request that we modify ourtraining or promotional or reimbursement materials or subject us to regulatory or enforcement actions, including, among other things, the issuance of anuntitled letter, a warning letter, injunction, seizure, disgorgement of profits, a civil fine and criminal penalties. Other federal, state or foreign governmentalauthorities also might take action if they consider our promotion or training materials to constitute promotion of an uncleared or unapproved use, whichcould result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. For example, thegovernment may take the position that off-label promotion resulted in inappropriate reimbursement for an off-label use in violation of the Federal FalseClaims Act for which it might impose a civil fine and even pursue criminal action. In those possible events, our reputation could be damaged, and adoptionof the products would be impaired. Although we train our sales force not to promote our products for off-label uses, and our instructions for use in all marketsspecify that our products are not intended for use outside of those indications cleared for use, the FDA or another regulatory agency could conclude that wehave engaged in off-label promotion. There may be increased risk of injury if surgeons attempt to use our products off-label. Furthermore, the use of our products for indications other thanthose indications for which our products have been cleared by the FDA may not effectively treat such conditions, which could harm our reputation in themarketplace among surgeons and patients. There may be increased risk of injury and product liability if surgeons misuse our products or do not follow recommended user and techniques andguidelines. Product liability claims are expensive to defend and could divert our management’s attention and result in substantial damage awards against us.Any of these events could harm our business and operating results. If our products cause or contribute to a death or a serious injury, or malfunction in certain ways, we will be subject to medical device reportingregulations, which can result in voluntary corrective actions or agency enforcement actions. Under the FDA medical device reporting regulations, medical device manufacturers are required to report to the FDA information that a device has ormay have caused or contributed to a death or serious injury or has malfunctioned in a way that would likely cause or contribute to death or serious injury ifthe malfunction of the device or one of our similar devices were to recur. Under the FDA’s reporting regulations applicable to human cells and tissue andcellular and tissue-based products (“HCT/Ps”), we are required to report all adverse reactions involving a communicable disease if it is fatal, life threatening,or results in permanent impairment of a body function or permanent damage to body structure. If we fail to report these events to the FDA within the requiredtimeframes, or at all, the FDA could take enforcement action against us. Any such adverse event involving our products also could result in future voluntarycorrective actions, such as recalls or customer notifications, or agency action, such as mandatory recalls, inspection or enforcement action. Any correctiveaction, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, would require the dedication of our time and capital, distractmanagement from operating our business, and may harm our reputation and financial results. 36 We may implement a product recall or voluntary market withdrawal due to product defects or product enhancements and modifications, which wouldsignificantly increase our costs. The FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products. In addition, foreigngovernmental bodies have the authority to require the recall of our products in the event of material deficiencies or defects in design or manufacture.Manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found. A government-mandated or voluntary recall byus or one of our distributors could occur as a result of component failures, manufacturing errors, design or labeling defects or other deficiencies and issues.Recalls of any of our products would divert managerial and financial resources and have an adverse effect on our financial condition and results ofoperations. The FDA requires that certain recalls undertaken to reduce a risk to health be reported to the FDA within 10 working days after the recall isinitiated. Companies are required to maintain certain records of recalls, even if they are not reportable to the FDA. We may initiate voluntary recallsinvolving our products in the future that we determine do not require notification of the FDA. If the FDA disagrees with our determinations, they couldrequire us to report those actions as recalls. A future recall announcement could harm our reputation with customers and negatively affect our sales. Inaddition, the FDA could take enforcement action for failing to report the recalls when they were conducted. In December 2018, we initiated a Class 2 recall of our Calix Lumbar Spine Implant System due to a risk of compromised sterilization of the product.There were no device related adverse events reported for this product and we are working with the FDA on this recall and expect to have it closed out in 2019. If we or our suppliers fail to comply with ongoing FDA or other regulatory authority requirements pertaining to Human Tissue Products, these productscould be subject to restrictions or withdrawal from the market. The FDA has statutory authority to regulate HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended fortransplantation into a human patient, including allograft-based products. The FDA, EU and Health Canada have been working to establish morecomprehensive regulatory frameworks for allograft-based, tissue-containing products, which are principally derived from cadaveric tissue. Certain of ourproducts are regulated as HCT/Ps and are not marketed pursuant to the FDA’s medical device regulatory authority, and therefore are not subject to FDAclearance or approval. Although we have not obtained premarket approval for these products, they are nonetheless subject to regulatory oversight. Humantissues intended for transplantation have been regulated by the FDA since 1993. Section 361 of the PHSA authorizes the FDA to issue regulations to prevent the introduction, transmission or spread of communicable disease.HCT/Ps regulated as 361 HCT/Ps are subject to requirements relating to: registering facilities and listing products with the FDA; screening and testing fortissue donor eligibility; current Good Tissue Practice, or cGTP, when processing, storing, labeling and distributing HCT/Ps, including required labelinginformation; stringent recordkeeping; and adverse event reporting. The FDA has also proposed extensive additional requirements that address sub-contractedtissue services, tracking to the recipient/patient, and donor records review. If a tissue-based product is considered human tissue, the FDA requirements focuson preventing the introduction, transmission and spread of communicable diseases. A product regulated solely as a 361 HCT/P is not required to undergopremarket clearance (510(k)) or approval (de novo or PMA). The FDA may inspect facilities engaged in manufacturing 361 HCT/Ps and may issue untitled letters, warning letters, or otherwise authorize ordersof retention, recall, destruction and cessation of manufacturing if the FDA has reasonable grounds to believe that an HCT/P or the facilities where it ismanufactured are in violation of applicable regulations. There also are requirements relating to the import of HCT/Ps that allow the FDA to make a decisionas to the HCT/Ps’ admissibility into the United States. An HCT/P is eligible for regulation solely as a 361 HCT/P if it is: (i) minimally manipulated; (ii) intended for homologous use as determined bylabeling, advertising or other indications of the manufacturer’s objective intent; (iii) the manufacture does not involve combination with another article,except for water, crystalloids or a sterilizing, preserving, or storage agent (not raising new clinical safety concerns for the HCT/P); and (iv) it does not have asystemic effect and is not dependent upon the metabolic activity of living cells for its primary function or, if it has a systemic effector is dependent upon themetabolic activity of living cells for its primary function, it is intended for autologous use or allogeneic use in a first or second degree relative or forreproductive use. If any of these requirements are not met, then the HCT/P is also subject to applicable biologic, device, or drug regulation under the FDCAor the PHSA. These biologic, device or drug HCT/Ps must comply both with the requirements exclusively applicable to 361 HCT/Ps and, in addition, withrequirements applicable to biologics under the PHSA, or devices or drugs under the FDCA, including premarket licensure, clearance or approval. 37 Over the course of several years, the FDA issued comprehensive regulations that address manufacturer activities associated with HCT/Ps. The firstrequires that companies that produce and distribute HCT/Ps register with the FDA. This set of regulations also includes the criteria that must be met in orderfor the HCT/P to be eligible for marketing solely under Section 361 of the PHSA and the regulations in 21 CFR Part 1271, rather than under the drug ordevice provisions of the FDCA or the biological product licensing provisions of the PHSA. The second set of regulations provides criteria that must be metfor donors to be eligible to donate tissues and is referred to as the “Donor Eligibility” rule. The third rule governs the processing and distribution of thetissues and is often referred to as the “Current Good Tissue Practices” rule. The “Current Good Tissue Practices” rule covers all stages of allograft processing,from procurement of tissue to distribution of final allografts. Together these regulations are designed to ensure that sound, high quality practices are followedto reduce the risk of tissue contamination and of communicable disease transmission to. At the time they came into effect approximately fifteen years ago, these regulations increased regulatory scrutiny within the industry in which weoperate and have led to increased enforcement action which affects the conduct of our business. In addition, these regulations can increase the cost of tissuerecovery activities. The FDA periodically inspects tissue processors to determine compliance with these requirements. Allegations of violations of applicableregulations noted by the FDA during facility inspections could adversely affect the continued marketing of our products. We believe we comply with allaspects of 21 CFR Part 1271 that we are required to comply with, although there can be no assurance that we will comply, or will comply on a timely basis, inthe future. Entities that provide us with allograft bone tissue are responsible for performing donor recovery, donor screening and donor testing and ourcompliance with those aspects of the Current Good Tissue Practices regulations that regulate those functions are dependent upon the actions of theseindependent entities. If our suppliers fail to comply with applicable requirements, our products and our business could be negatively affected. If the FDAdetermines that we have failed to comply with applicable regulatory requirements, it can impose a variety of enforcement actions from public warning letters,fines, injunctions, consent decrees and civil penalties to suspension or delayed issuance of approvals, seizure of our products, total or partial shutdown of ourproduction, withdrawal of approvals, and criminal prosecutions. If any of these events were to occur, it could materially adversely affect us. In addition, the FDA could disagree with our conclusion that some of our HCT/Ps meet the criteria for marketing solely under Section 361 of thePHSA, and therefore do not require approval or clearance of a marketing application. For our HCT/Ps that are not combined with another article, the FDAcould conclude that the tissue is more than minimally manipulated, that the product is intended for a non-homologous use, or that the product has a systemiceffect or is dependent on the metabolic activity of living cells for its primary function. If the FDA were to draw these conclusions, it would likely require thesubmission and approval or clearance of a marketing application in order for us to continue to market the product. Such an action by the FDA could causenegative publicity, decreased or discontinued product sales, and significant expense in obtaining required marketing approval or clearance. Procurement of certain human organs and tissue for transplantation, including allograft tissue we may use in future products, is subject to federalregulation under National Organ Transplant Act. NOTA prohibits the acquisition, receipt, or other transfer of certain human organs, including bone and otherhuman tissue, for valuable consideration within the meaning of NOTA. NOTA permits the payment of reasonable expenses associated with the removal,transportation, implantation, processing, preservation, quality control and storage of human organs. For any future products implicating NOTA’srequirements, we would reimburse tissue banks for their expenses associated with the recovery, storage and transportation of donated human tissue that theywould provide to us. NOTA payment allowances may be interpreted to limit the amount of costs and expenses that we may recover in our pricing for ourservices, thereby negatively impacting our future revenue and profitability. If we were to be found to have violated NOTA’s prohibition on the sale or transferof human tissue for valuable consideration, we would potentially be subject to criminal enforcement sanctions, which could materially and adversely affectour operating results. Further, in the future, if NOTA is amended or reinterpreted, we may not be able to pass these expenses on to our customers and, as aresult, our business could be adversely affected. Other regulatory entities with authority over our products and operations include state agencies enforcing statutes and regulations covering tissuebanking. Regulations issued by Florida, New York, California and Maryland will be particularly relevant to our business. Most states do not currently havetissue banking regulations. It is possible that others may make allegations against us or against donor recovery groups or tissue banks about non-compliancewith applicable FDA regulations or other relevant statutes or regulations. 38 Allegations like these could cause regulators or other authorities to take investigative or other action or could cause negative publicity for ourbusiness and the industry in which we operate. Our products may be subject to regulation in the European Union (“EU”) as well, should we enter that market. In the European Union regulations, ifapplicable, differ from one EU member state to the next. Because of the absence of a harmonized regulatory framework and the proposed regulation foradvanced therapy medicinal products in the European Union, as well as for other countries, the approval process for human derived cell or tissue basedmedical products may be extensive, lengthy, expensive and unpredictable. Some of our products may be subject to EU member states’ regulations thatgovern the donation, procurement, testing, coding, traceability, processing, preservation, storage, and distribution of human tissues and cells and cellular ortissue-based products. Some EU member states have their own tissue banking regulations. Loss of AATB Accreditation would have a material adverse effect on us. We are accredited with the American Association of Tissue Banks (“AATB”), a private non-profit organization that accredits tissue banks and setsindustry standards. Although AATB accreditation is voluntary and not required by law, as a practical matter, many of our customers would not purchase ourproducts if we failed to maintain our AATB accreditation. Although we make every effort to maintain our AATB accreditation, the accreditation process issomewhat subjective and lacks regulatory oversight. There can be no assurance that we will continue to remain accredited with the AATB. Federal regulatory reforms may adversely affect our ability to sell our products profitably. From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing theregulatory approval, manufacture and marketing of regulated products or the reimbursement thereof. In addition, FDA regulations and guidance are oftenrevised or reinterpreted by the FDA in ways that may significantly affect our business and our products. Any new regulations or revisions or reinterpretationsof existing regulations may impose additional costs or lengthen review times of future products. In addition, FDA regulations and guidance are often revisedor reinterpreted by the agency in ways that may significantly affect our business and our products. It is impossible to predict whether legislative changes willbe enacted or FDA regulations, guidance or interpretations changed, and what the impact of such changes, if any, may be. For example, the FDA may change its clearance and approval policies, adopt additional regulations or revise existing regulations, or take otheractions which may prevent or delay approval or clearance of our products under development or impact our ability to modify our currently cleared productson a timely basis. Any change in the laws or regulations that govern the clearance and approval processes relating to our current and future products couldmake it more difficult and costly to obtain clearance or approval for new products, or to produce, market and distribute existing products. Significant delaysin receiving clearance or approval, or the failure to receive clearance or approval for our new products would have an adverse effect on our ability to expandour business. Product pricing (and, therefore, profitability) is subject to regulatory control which could impact our revenue and financial performance. The pricing and profitability of our products may become subject to control by the government and other third-party payors. The continuing effortsof governmental and other third-party payors to contain or reduce the cost of healthcare through various means may adversely affect our ability tosuccessfully commercialize our products. In most foreign markets, the pricing and/or profitability of certain diagnostics and prescription pharmaceuticals aresubject to governmental control. In the United States, we expect that there will continue to be federal and state proposals to implement similar governmentalcontrol, though it is unclear which proposals will ultimately become law, if any. Changes in prices, including any mandated pricing, could impact ourrevenue and financial performance. 39 Our revenues depend upon prompt and adequate coverage and reimbursement from public and private insurers and national health systems. Political, economic and regulatory influences are subjecting the healthcare industry, including the medical device industry, in the United States tofundamental change. The ability of hospitals to purchase our products depends in part on the extent to which reimbursement for the costs of such materialsand related treatments will continue to be available from governmental health administration authorities, private health coverage insurers and otherorganizations. In the United States, healthcare providers who purchase our products generally rely on these third-party payors to pay for all or a portion of thecost of our products as a component of a single bundled payment amount for the procedures in which the products are used. Because there is often no separatethird-party payor reimbursement to the provider for our products, the additional cost associated with purchasing our products can impact the provider’s profitmargin. If third-party payor reimbursement to providers for procedures involving our products decreases, some of our target customers may be unwilling topurchase our products in favor of purchasing less expensive alternatives. In addition, third-party payors of hospital services and hospital outpatient services,including Medicare, Medicaid and private healthcare insurers, annually revise their payment methodologies and amounts, which can result in stricterstandards for reimbursement of hospital charges for certain medical procedures or the elimination of or reduction in reimbursement. Further, Medicare,Medicaid and private healthcare insurer cutbacks could create downward price pressure on our products. All of these factors could adversely affect ourbusiness. Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which couldhave a material adverse effect on our business. We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include failures to comply with FDAregulations, provide accurate information to the FDA, comply with manufacturing and reporting standards we have established, comply with federal and statehealthcare fraud and abuse laws and regulations, report financial information or data accurately, or disclose unauthorized activities to us. In particular, sales,marketing, and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing, and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, salescommission, customer incentive programs, and other business arrangements. Employee misconduct could also involve the improper use of informationobtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. If any such actions are institutedagainst us, and we are not successful in defending ourselves or asserting our rights, those actions could have a substantial impact on our business and resultsof operations, including the imposition of substantial fines or other sanctions. Risks Related to Our Intellectual Property If we lose any existing or future intellectual property lawsuits, a court could require us to pay significant damages or prevent us from selling our products. The medical device industry is litigious with respect to patents and other intellectual property rights. Companies in the medical device industryhave used intellectual property litigation to gain a competitive advantage. In December 2018, a complaint was filed by RSB Spine, LLC against us whichclaims that some of our products, including the Irix-ATM Lumbar Integrated Fusion System and the Irix-CTM Cervical Integrated Fusion System, infringecertain of RSB Spine’s patents. The complaint seeks, among other relief, an injunction against future infringement, unspecified damages for infringement,and treble damages for willful infringement. Legal proceedings, regardless of the outcome, could drain our financial resources and divert the time and effortof our management. If we lose one of these proceedings, a court could require us to pay significant damages to third parties, indemnify third parties from loss,require us to seek licenses from third parties, pay ongoing royalties, redesign our products, or prevent us from manufacturing, using or selling our products. Inaddition to being costly, protracted litigation to defend or prosecute our intellectual property rights could result in our customers or potential customersdeferring or limiting their purchase or use of the affected products until resolution of the litigation. 40 If our patents and other intellectual property rights do not adequately protect our products, we may lose market share to our competitors and be unable tooperate our business profitably. We rely on patents, trade secrets, copyrights, know-how, trademarks, license agreements, and contractual provisions to establish our intellectualproperty rights and protect our products. These legal means, however, afford only limited protection and may not completely protect our rights, for example,competitors may be able to design around some of our intellectual property rights to develop competing but non-infringing technologies. In addition, wecannot be assured that any of our pending patent applications will issue. The U.S. Patent and Trademark Office (or applicable foreign intellectual propertyoffice) may deny or require a significant narrowing of the claims in its pending patent applications and the patents issuing from such applications. Anypatents issuing from the pending patent applications may not provide us with significant commercial protection or sufficient commercial protection toprevent competitors from utilizing similar but non-infringing technologies. We could incur substantial costs in proceedings before the U.S. Patent andTrademark Office. These proceedings could result in adverse decisions as to the priority of our inventions and the narrowing or invalidation of claims inissued patents. In addition, the laws of some of the countries in which our products are or may be sold may not protect our intellectual property to the sameextent as U.S. laws or at all. We also may be unable to protect our rights in trade secrets and unpatented proprietary technology in these countries. In addition, we hold licenses from third parties that are necessary to utilize certain technologies used in the design and manufacturing of some of ourproducts. The loss of such licenses would prevent us from manufacturing, marketing, and selling these products, which could harm our business. If we, or theother parties from whom we would license intellectual property, fail to obtain and maintain adequate patent or other intellectual property protection forintellectual property used in our products, or if any protection is reduced or eliminated, others could use the intellectual property used in our products,resulting in harm to our competitive business position. We seek to protect our trade secrets, know-how, and other unpatented proprietary technology, in part, with confidentiality agreements with ouremployees, independent distributors, and consultants. We cannot be assured, however, that the agreements will not be breached, adequate remedies for anybreach would be available, or our trade secrets, know-how, and other unpatented proprietary technology will not otherwise become known to orindependently developed by our competitors. We may not be able to obtain or protect our proprietary rights relating to our products without resorting to costly and time-consuming litigation. We may not be able to obtain, maintain and protect certain proprietary rights necessary for the development and commercialization of our productsor product candidates. Our commercial success will depend in part on obtaining and maintaining patent protection on our products, successfully assertingthese patents against competitors employing infringing technology, and successfully defending these patents against third-party challenges. Even if ourpatents cover a competing technology, a competitor may not accede to our demands to cease and desist or license our patent rights, which will then require usto pursue costly and time-consuming litigation. Our ability to commercialize our products will also depend in part on the patent positions of third parties,including those of our competitors. The patent positions of medical device and biotechnology companies can be highly uncertain and involve complex legaland factual questions. Accordingly, we cannot predict with certainty the scope and breadth of patent claims that may be afforded to other companies’ patents.We could incur substantial costs in litigation if we are required to defend against patent suits brought by third parties, or if we initiate suits to protect ourpatent rights. Such suits that we may need to defend extend beyond suits by our competitors and may include patent assertion entities, which acquire andassert patents as a means to generate income, due to the expensive nature of patent litigation. In the ordinary course of litigation, attorney fees are notrecoverable. In addition to the risks involved with patent protection, we also face the risk that our competitors will infringe on our trademarks. Any infringementcould lead to a likelihood of confusion and could result in lost sales. Similarly, while we are cautious to avoid infringing the rights of third parties, we cannotcontrol a third party asserting its trademarks against us. There can be no assurance that we will prevail in any claims we make to protect our intellectualproperty, or in defense of any claims brought against us. 41 Future protection for our proprietary rights is uncertain which may impact our ability to successfully compete in our industry. The degree of futureprotection for our proprietary rights is uncertain. We cannot ensure that: ●we were the first to make the inventions covered by each of our patent applications; ●we were the first to file patent applications for these inventions; ●others will not independently develop similar or alternative technologies or duplicate any of our technologies; ●any of our pending patent applications will result in issued patents; ●any of our issued patents or those of our licensors will be valid and enforceable; ●any patents issued to us or our collaborators will provide a basis for commercially viable products or will provide us with any competitiveadvantages or will not be challenged by third parties; ●any of our patent or other intellectual property rights in the U.S. and the technologies embodied therein will provide or be subject to similar orany protection in foreign markets; ●we will develop additional proprietary technologies that are patentable; ●the patents of others will not have a material adverse effect on our business rights; or ●the measures we rely on to protect the intellectual property underlying our products will be adequate to prevent third parties from using ourtechnology, all of which could harm our ability to compete in the market. Risks Related to Our Common Stock Shares of our common stock are equity securities and are subordinate to our outstanding indebtedness, which is significant. Shares of our common stock are common equity interests. This means that our common stock will rank junior to any outstanding shares of ourpreferred stock that we may issue in the future or to the indebtedness under our Second Amended and Restated Credit Agreement and any future indebtednesswe may incur and to all creditor claims and other non-equity claims against us and our assets available to satisfy claims on us, including claims in abankruptcy or similar proceeding. Additionally, unlike indebtedness, where principal and interest customarily are payable on specified due dates, in the caseof our common stock, (i) dividends are payable only when and if declared by our board of directors or a duly authorized committee of our board of directors,and (ii) as a corporation, we are restricted to making dividend payments and redemption payments out of legally available assets. We have never paid adividend on our common stock and have no current intention to pay dividends in the future. Furthermore, our common stock places no restrictions on ourbusiness or operations or on our ability to incur indebtedness or engage in any transactions, subject only to the voting rights available to stockholdersgenerally. Funds affiliated with OrbiMed own, in the aggregate, approximately 70% of our outstanding common stock, and beneficially own, with their warrants,approximately 75%, and hold all of our outstanding indebtedness and therefore can exert significant influence or control over our corporate matters. Funds affiliated with OrbiMed Advisors LLC, OrbiMed Royalty Opportunities II, LP (“Royalty Opportunities”) and ROS Acquisition Offshore LP(“ROS”), own approximately 70% of our outstanding common stock and beneficially own, with their warrants, approximately 75% of our outstandingcommon stock. Pursuant to an Investor Rights Agreement, dated as of February 14, 2018 (“Investor Rights Agreement”), by and among the Company andcertain stockholders, including without limitation, Royalty Opportunities and ROS, for so long as the Ownership Threshold (as defined in the Investor RightsAgreement) is met, these funds are entitled to nominate such individuals to the Board of Directors constituting a majority of the directors. MichaelEggenberg, Matthew Rizzo and Jeffrey Peters are currently the three director representatives per the terms of the Investor Rights Agreement. In addition,Royalty Opportunities and ROS are the lenders under our Second Amended and Restated Credit Agreement and hold all of our outstanding indebtednessthereunder and hold warrants to purchase in the aggregate an additional 2,407,309 shares of our common stock. Because of their significant share ownershipand control, OrbiMed has the ability to exert substantial influence or actual control over our management and affairs and over substantially all mattersrequiring action by our stockholders, including amendments to our Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws,election and removal of directors, any proposed merger, consolidation or sale of all or substantially all of our assets and other corporate transactions. Thisconcentration of ownership may delay or prevent a change in control otherwise favored by our other stockholders and could depress our stock price. 42 We are a “controlled company” within the meaning of the NYSE American rules and rely on exemptions from various corporate governance requirements. We are a “controlled company” as defined in section 801(a) of the NYSE American Company Guide because more than 50% of the combined votingpower of all of our outstanding common stock is beneficially owned by OrbiMed Advisors LLC. As a “controlled company,” we are exempt from certainNYSE American rules requiring our board of directors to have a majority of independent members, a compensation committee composed entirely ofindependent directors and a nominating committee composed entirely of independent directors. These independence standards are intended to ensure thatdirectors who meet those standards are free of any conflicting interest that could influence their actions as directors. We rely on NYSE American’s controlledcompany exemptions and do not have a majority of independent directors on the Board, an independent nomination and governance committee or anindependent compensation committee. Accordingly, you do not have the same protections afforded to stockholders of companies that are subject to all of thecorporate governance requirements of the NYSE American rules. We are subject to the continued listing standards of the NYSE American and our failure to satisfy these criteria may result in the delisting of our commonstock. Our common stock is listed on the NYSE American. In order to maintain this listing, we must maintain certain share prices, financial and sharedistribution targets, including maintaining a minimum amount of shareholders’ equity and a minimum number of public shareholders. In addition to theseobjective standards, the NYSE American may delist the securities of any issuer (i) if, in its opinion, the issuer’s financial condition and/or operating resultsappear unsatisfactory; (ii) if it appears that the extent of public distribution or the aggregate market value of the security has become so reduced as to makecontinued listing on the NYSE American inadvisable; (iii) if the issuer sells or disposes of principal operating assets or ceases to be an operating company;(iv) if an issuer fails to comply with the NYSE American’s listing requirements; (v) if an issuer’s common stock sells at what the NYSE American considers a“low selling price” and the issuer fails to correct this via a reverse split of shares after notification by the NYSE American; or (vi) if any other event occurs orany condition exists which makes continued listing on the NYSE America, in its opinion, inadvisable. As part of these continued listing requirements, we must maintain stockholders’ equity of $6.0 million or more since we have reported losses fromcontinuing operations and/or net losses in our five most recent fiscal years under Section 1003(a)(iii) of the NYSE American Company Guide. Our auditedconsolidated financial statements for the year ended December 31, 2018 reflect stockholders’ deficit of $43.8 million. According to Section 1003(a) of theCompany Guide, the NYSE American will normally consider providing an exemption for entities not in compliance with Section 1003(a)(iii) of the CompanyGuide if the entity is in compliance with the following standards: (1) total value of market capitalization of at least $50,000,000; or total assets and revenueof $50,000,000 each in its last fiscal year, or in two of its last three fiscal years; and (2) the issuer has at least 1,100,000 shares publicly held, a market value ofpublicly held shares of at least $15,000,000 and 400 round lot shareholders. No assurance can be provided, however, that the Company will be able to meetthis exemption. If we fail to meet these continued listing requirements, we may receive a deficiency notice by the NYSE American that we are not in compliance withthe requirements set forth in the NYSE American Company Guide. In response to this notice, we would likely submit to the NYSE American a plan to regaincompliance with the requirements. If NYSE Regulation does not approve our plan or if we are unable to regain compliance by the end of the cure periodwhich we expect to receive or if the NYSE American determines that we are not making progress consistent with the plan during the plan period, the NYSEAmerican may initiate suspension and delisting procedures. If delisting proceedings are commenced, the NYSE American rules permit us to appeal a staffdelisting determination. Our common stock will continue to be listed and traded on the NYSE American during the plan period, subject to our compliancewith the NYSE American’s other applicable continued listing standards. If the NYSE American delists our common stock, investors may face material adverseconsequences, including, but not limited to, a lack of trading market for our securities, reduced liquidity, decreased analyst coverage of our securities, and aninability for us to obtain additional financing to fund our operations. 43 The market price of our common stock is extremely volatile, which may affect our ability to raise capital in the future and may subject the value of yourinvestment to sudden decreases. The market price for securities of medical device and biotechnology companies, including ours, historically has been highly volatile, and the marketfrom time to time has experienced significant price and volume fluctuations that are unrelated to the operating performance of such companies. The tradingvolume and prices of our common stock have been and may continue to be volatile and could fluctuate widely due to factors beyond our control. During2018, the sale price of our common stock ranged from $1.61 to $11.50 per share, after giving effect to the one-for-12 reverse stock split effected on February13, 2018. Such volatility may be the result of broad market and industry factors. Future fluctuations in the trading price or liquidity of our common stockmay harm the value of your investment in our common stock. Factors that may have a significant impact on the market price and marketability of ourcommon stock include: ●the terms of any potential future debt restructuring or reorganization; ●our ability to make interest payments under our Second Amended and Restated Credit Agreement; ●our observance of covenants under our Second Amended and Restated Credit Agreement; ●announcements of technological innovations or new commercial products by us or our present or potential competitors; ●developments or disputes concerning patent or other proprietary rights; ●developments in our relationships with employees, suppliers, distributors, sales representatives and customers; ●acquisitions or divestitures; ●litigation and government proceedings; ●adverse legislation, including changes in governmental regulation; ●third-party reimbursement policies; ●additions or departures of key personnel; ●sales of our equity securities by our significant stockholders or management or sales of additional equity securities by our company; ●changes in securities analysts’ recommendations; ●short selling; ●changes in health care policies and practices; ●the delisting of our common stock or halting or suspension of trading in our common stock by the NYSE American; ●economic and other external factors; and ●general market conditions. 44 In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted.These lawsuits often seek unspecified damages, and as with any litigation proceeding, one cannot predict with certainty the eventual outcome of pendinglitigation. Furthermore, we may have to incur substantial expenses in connection with any such lawsuits and our management’s attention and resources couldbe diverted from operating our business as we respond to any such litigation. We maintain insurance to cover these risks for us and our directors and officers,but our insurance is subject to high deductibles to reduce premium expense, and there is no guarantee that the insurance will cover any specific claim that wecurrently face or may face in the future, or that it will be adequate to cover all potential liabilities and damages. We may issue additional common stock resulting in stock ownership dilution. Future dilution may occur due to additional future equity issuances and/or equity financing events by us, including any potential futurerestructuring of our outstanding indebtedness. In addition, we may raise additional capital through the sale of equity or convertible debt securities whichwould further dilute the ownership interests of our stockholders. In addition, if outstanding options or warrants or are exercised or otherwise converted intoshares of our common stock, our stockholders will experience additional dilution. The sale or availability for sale of substantial amounts of our securities could adversely affect their market price. Sales of substantial amounts of our common stock or a preferred stock in the public market, or the perception that these sales could occur, couldadversely affect the market price of our common stocks and could materially impair our ability to raise capital through equity offerings in the future. Wecannot predict what effect, if any, market sales of securities beneficially owned by OrbiMed or any other stockholder or the availability of these securities forfuture sale will have on the market price of our common stock. If securities analysts stop publishing research or reports about us or our business, or if they downgrade our common stock, the trading volume and marketprice of our common stock could decline. The market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our business. We donot control these analysts. If any analyst who covers us downgrades our stock or lowers its future stock price targets or estimates of our operating results, ourstock price could decline rapidly. Furthermore, if any analyst ceases to cover our Company, we could lose visibility in the market. Each of these events could,in turn, cause our trading volume and the market price of our common stock to decline. We could issue “blank check” preferred stock without stockholder approval with the effect of diluting interests of then-current stockholders and impairingtheir voting rights, and provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may considerfavorable. Our Amended and Restated Certificate of Incorporation provides for the authorization to issue up to 10,000,000 shares of “blank check” preferredstock with designations, rights and preferences as may be determined from time to time by the Board of Directors. The Board of Directors is empowered,without stockholder approval, to issue one or more series of preferred stock with dividend, liquidation, conversion, voting or other rights which could dilutethe interest of, or impair the voting power of, our common stockholders. The issuance of a series of preferred stock could be used as a method of discouraging,delaying or preventing a change in control. For example, it would be possible for our board of directors to issue preferred stock with voting or other rights orpreferences that could impede the success of any attempt to change control of our company. In addition, advanced notice is required prior to stockholderproposals, which might further delay a change of control. 45 We have never paid dividends and do not expect to do so in the foreseeable future. We have not declared or paid any cash dividends on our common stock. The payment of dividends in the future will be dependent on our earningsand financial condition and on such other factors as our Board of Directors considers appropriate. Unless and until we pay dividends, stockholders may notreceive a return on their shares. There is no present intention by our Board of Directors to pay dividends on our common stock. We currently intend to retainall of our future earnings, if any, to finance the growth and development of our business. In addition, the terms of our Second Amended and Restated CreditAgreement preclude us from paying dividends. As a result, appreciation, if any, in the market price of our common stock will be your sole source of gain forthe foreseeable future. Item 1B.Unresolved Staff Comments This Item 1B is inapplicable to Xtant as a smaller reporting company. Item 2.Properties We lease approximately 17,700 square feet in a building located at 600 Cruiser Lane, Belgrade, Montana 59714.

We also lease a facility at 452 Alexandersville Road, Miamisburg, Ohio 45342. The leased property contains approximately 31,600 square feet. TheCompany’s offices and operations at this facility were transferred to the Company’s facilities in Belgrade, Montana in the fourth quarter of 2017. Thefacilities are leased under a three-year lease which runs through November 2019. As of February 28, 2019, we terminated our Miamisburg, OH lease, whichwas set to expire December 1, 2019. Item 3.Legal Proceedings On December 13, 2018, a complaint was filed by RSB Spine, LLC against Xtant Medical Holdings, Inc. which claims that some of our products,including the Irix-ATM Lumbar Integrated Fusion System and the Irix-CTM Cervical Integrated Fusion System, infringe certain of RSB Spine’s patents. Thecomplaint seeks an adjudication of infringement, an injunction against future infringement, unspecified damages for infringement, a finding that suchinfringement is willful, and treble damages for such willful infringement. This action was brought in the United States District Court for the District ofDelaware. We intend to vigorously defend the claims in this action. Because this matter is in early stages and because of the complexity of the case, wecannot estimate the possible loss or range of loss, if any, associated with its resolution. However, there can be no assurance that the ultimate resolution of thismatter will not result in a material adverse effect on our business, financial condition or results of operations. 46 On August 10, 2017, a civil suit complaint was filed against Xtant in the United States District Court, District of Nevada by Axis Spine NV, LLC(“Axis”), Case No. 2:17-CV-02147-APG-VCF. The complaint alleges breach of contract, breach of the implied covenant of good faith and fair dealing, andtortious interference with prospective economic advantage with respect to an alleged medical device distribution relationship between the parties.Specifically, Axis alleges that Xtant owes payments to Axis for its medical device distributions. Axis seeks relief in the form of damages in an amount inexcess of $1.0 million. On March 6, 2019, the Court granted Xtant’s motion for summary judgment on Axis’s claims for breach of contract, and breach of thecovenant of good faith and fair dealing but denied Xtant’s motion for summary judgment on Axis’s unjust enrichment claim. Xtant is evaluating itsalternatives in light of the court order. Because this matter is in early stages and because of the complexity of the case, we cannot estimate the possible loss orrange of loss, if any, associated with its resolution. However, there can be no assurance that the ultimate resolution of this matter will not result in a materialadverse effect on our business, financial condition or results of operations. In October 2016, Phoenix Surgical, Inc., a former distributor sued Xtant for its alleged participation in a scheme orchestrated by a former PhoenixSurgical sales representative to divert sales away from Phoenix Surgical to another entity. The other entity diverted approximately $285,000 in sales (orapproximately $205,000 in gross profit) that would otherwise have gone to Phoenix Surgical. Phoenix Surgical alleges that Xtant and one of its formeremployees participated in this diversion of sales and that Xtant is liable to Phoenix Surgical for its loss, with treble damages for violation of a Connecticutstatute. Xtant claims that the other entity was a legitimate distributor, its former employee acted on his own and Xtant had no way of knowing the otherparties were diverting sales. Phoenix initially sued Xtant in Connecticut and in federal bankruptcy court because some other individuals involved have filedbankruptcy. Xtant was dismissed from those actions, and the dispute is now subject to arbitration in Colorado. The arbitration is scheduled for July 2019. Item 4.Mine Safety Disclosures Not applicable. 47 PART II Item 5.Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Market Information Our common stock is listed on the NYSE American under the ticker symbol “XTNT.” Holders of Record As of March 29, 2019, we had 174 holders of record. Dividends We have not paid any cash dividends and do not expect to do so in the foreseeable future. In addition, our Second Amended and Restated CreditAgreement precludes us from paying dividends. Recent Sales of Unregistered Securities On March 29, 2019, we entered into the Second Amended and Restated Credit Agreement with OrbiMed Royalty Opportunities II, LP and ROSAcquisition Offshore LP (collectively, the “Investors”), as described in Item 9B below. As a condition to the effectiveness of the Second Amended andRestated Credit Agreement, on April 1, 2019, the Company will issue warrants to purchase an aggregate of 1.2 million shares of our Common Stock to theInvestors, with an exercise price of $0.01 per share and an expiration date of April 1, 2029 (collectively, the “2019 Warrants”). The issuance of the 2019Warrants was exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Section 4(a)(2) thereofand/or Regulation D promulgated thereunder. The issuance of any shares of our Common Stock in connection with the exercise of the 2019 Warrants is alsoexpected to be exempt from the registration requirements of the Securities Act, pursuant to Section 4(a)(2) thereof and/or Regulation D promulgatedthereunder. Purchases of Equity Securities by the Issuer and Affiliated Purchasers Not applicable. Item 6.Selected Financial Data This Item 6 is inapplicable to Xtant as a smaller reporting company. 48 Item 7.Management’s Discussion and Analysis of Financial Condition and Results of Operation This Management’s Discussion and Analysis provides material historical and prospective disclosures intended to enable investors and other usersto assess our financial condition and results of operations. The following discussion should be read in conjunction with our consolidated financialstatements and accompanying notes included in this Annual Report on Form 10-K. In addition to historical financial information, the following discussionand analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Some of the numbers included herein have beenrounded for the convenience of presentation. Our actual results may differ materially from those anticipated in these forward-looking statements as a resultof many factors, including those discussed in the “Cautionary Statement Regarding Forward-Looking Statements” and under the heading “Part I. Item 1A.Risk Factors.” Executive Summary We develop, manufacture and market regenerative medicine products and medical devices for domestic and international markets. Our productsserve the specialized needs of orthopedic and neurological surgeons, including orthobiologics for the promotion of bone healing, implants andinstrumentation for the treatment of spinal disease. We promote our products in the United States largely through independent distributors and stockingagents, augmented by direct employees. During the first quarter of 2018, we effected a significant restructuring pursuant to which we converted an aggregate of $71.9 million of aggregateprincipal amount of debt into equity by issuing an aggregate of 10,590,954 shares of our common stock, in cancellation thereof; issued an additional945,819 shares of our common stock in a private placement for an aggregate purchase price of $6.8 million, completed a 1-for-12 reverse split of our commonstock after the close of business on February 13, 2018, and replaced our entire Board of Directors. We completed this restructuring during the second quarterof 2018 with a common stock stockholder rights offering, which expired on June 18, 2018 and resulted in the issuance of an additional 129 shares ofcommon stock. Upon completion of this restructuring and as of December 31, 2018, two funds affiliated with OrbiMed, which held a significant portion ofour converted indebtedness and continue to hold all of our currently outstanding debt, own approximately 70% of our outstanding common stock. Becauseof this significant ownership, we are a “controlled company” within the meaning of the NYSE American corporate governance standards. During 2018, we experienced reduced revenues due primarily to company-initiated discontinued distributor arrangements and challenges in channelmanagement, the highly competitive fixation distribution network, and no new product introductions over the past two years. We focused on reducing ouroperating expenses during 2018, which resulted in a 19.3% decrease in general and administrative expenses, a 20.9% decrease in sales and marketingexpenses and a 30.5% decrease in research and development expenses compared to 2017. These decreases, however, were offset by a significant non-cashimpairment of goodwill charge of $38.3 million and impairment of intangible assets charge of $9.8 million during the fourth quarter of 2018 relatingprimarily to assets acquired in connection with our 2015 X-spine acquisition. As of December 31, 2018, our cash and cash equivalents were $6.8 million. On March 29, 2019, we entered into a Second Amended and Restated Credit Agreement with our lenders (the “Second Amended and Restated CreditAgreement”), which amended and restated our prior Amended and Restated Credit Agreement dated as of July 27, 2015 among the parties thereto, and assubsequently amended through the Twenty-Fifth Amendment to the Amended and Restated Credit Agreement, the “Prior Credit Agreement”). Under the terms of the Second Amended and Restated Credit Agreement, the Prior Credit Agreement was amended to provide that: ●X-Spine may request additional term loans with ROS and Royalty Opportunities in the remaining amount available as Additional Delayed DrawLoans, and may make a request for new term loans in an aggregate amount of up to $10,000,000, the amount of each loan draw to be subject to ourproduction of a thirteen-week cash flow forecast that is approved by ROS and Royalty Opportunities and shows a projected cash balance for thefollowing two-week period of less than $1,500,000, as well as the satisfaction (or waiver in writing by each lender) of conditions precedent,including closing certificate, delivery of budget, and other satisfactory documents;●No interest will accrue on the Loans under the Second Amended and Restated Credit Agreement from and after January 1, 2019 until March 31,2020;●Beginning April 1, 2020 through the maturity date of the Second Amended and Restated Credit Agreement, interest payable in cash will accrue onthe Loans under the Credit Agreement at a rate per annum equal to the sum of (i) 10.00% plus (ii) the higher of (x) the LIBO Rate (as such term isdefined in the Second Amended and Restated Credit Agreement) and (y) 2.3125%;●The maturity date of the Loans is March 31, 2021;●The Consolidated Senior Leverage Ratio and Consolidated EBITDA (as such terms were defined in the Credit Agreement) financial covenants weredeleted and a new Revenue Base (as such term is defined in the Second Amended and Restated Credit Agreement) financial covenant was added;and●The key person event default provision was revised to refer specifically to Kevin Brandt and Ron Berlin. 49 Comparison of Years Ended December 31, 2018 and December 31, 2017 (in thousands): The following table sets forth our results of operations for 2018 and 2017.

The decrease of$10.4 million is primarily due to company-initiated discontinued distributor arrangements and challenges in channel management the highly competitivefixation distribution network, and no new product introductions over the past two years. 50 Cost of Sales Costs of sales consist primarily of manufacturing and product purchase costs and depreciation of surgical trays. Cost of sales also includes reservesfor estimated excess inventory, inventory on consignment that may be missing and not returned, and reserves for estimated missing and damaged consignedsurgical instruments. Cost of sales decreased by 11.7%, or $3.8 million, to $28.7 million for the year ended December 31, 2018 from $32.5 million for theyear ended December 31, 2017. This was primarily due to manufacturing cost savings achieved during 2018 as a result of the consolidation of facilitiesfollowing the closure of our Dayton, Ohio operations in early 2018 and cost reduction initiatives to fully integrate hardware and biologics operations at thebeginning of 2018. Cost of sales as a percent of total revenue was 39.8% of revenue for the year ended December 31, 2018, compared to 39.4% for the prioryear. Reserves for estimated excess inventory, inventory on consignment that may be missing and not returned, and estimated missing and damagedconsigned surgical instruments were $4.6 million in 2018 and $4.0 million in 2017. The reserve for 2018 was due primarily to the significant decrease infixation sales and our change in estimate for determining excess and obsolete inventory to include 100% of fixation products with quantity on hand greaterthan two years of sales. The reserve for 2017 was due, in part, to litigation with a certain distributor. Operating Expenses Operating expenses include general and administrative expenses, sales and marketing expenses, research and development expenses, depreciationand amortization, impairment of goodwill and intangible assets, restructuring expenses and compensation costs, including separation related expenses andincentive compensation. Operating expenses increased 17.8%, or $15.6 million, for the year ended December 31, 2018 compared to the year ended December31, 2017, primarily due to the $48.1 million impairment of goodwill and intangible assets. Almost all other components of operating expenses decreasedduring 2018 compared to 2017. General and Administrative General and administrative expenses consist principally of personnel costs for corporate employees, cash based and stock-based compensationrelated costs and corporate expenses for legal, accounting and other professional fees, as well as occupancy costs. General and administrative expensesdecreased 15.5%, or $2.4 million, to $12.9 million for the year ended December 31, 2018, compared to the year ended December 31, 2017. The reduction inexpenses is largely the result of decreased bad debt expense, personnel costs, and legal expenses incurred in 2018 compared to 2017. Sales and Marketing Sales and marketing expenses consist primarily of sales commissions, personnel costs for sales and marketing employees, costs for trade shows, salesconventions and meetings, travel expenses, advertising and other sales and marketing related costs. Sales and marketing expenses decreased 20.9%, or $8.5million, to $32.1 million for the year ended December 31, 2018, compared to $40.5 million for of the year ended December 31, 2017. As a percentage ofrevenue, sales and marketing expenses were 44.4% in 2018 and 49.0% in the prior year. This reduction in sales and marketing expenses as a percent ofrevenue was primarily the result of changes made to the commission rate structure under certain distribution agreements, lower sales commissions, personnelreductions and a decline of other direct marketing expenses. Research and Development Research and development expenses consist primarily of internal costs for the development of new product technologies and processes. Researchand development expenses decreased $0.7 million, or 30.3%, to $1.7 million for the year-ended December 31, 2018 from $2.4 million for the year endedDecember 31, 2017. The decrease is primarily due to the consolidation of the Dayton, Ohio, facility and the corresponding reduction in headcount. Depreciation and Amortization Depreciation and amortization expense consist of depreciation and amortization of long-lived intangible assets, patents, leasehold improvementsand equipment. Depreciation and amortization expense decreased $1.4 million to $4.1 million for the year ended December 31, 2018, from $5.5 million forthe year ended December 31, 2017 primarily due to lower new capital investments in 2018. 51 Impairment of Goodwill and Intangible Assets The Company recorded an impairment charge in 2018 of $38.3 million to Goodwill based on the analysis performed in comparing the carryingvalue of assets, including cash, and non-interesting bearing liabilities to the derived enterprise value of the business. The Company also recorded an impairment charge in 2018 of $9.8 million to Tradenames, Technology and Customer Relationships and in 2017 of$17.6 million related to Technology and Tradenames based on the carrying amount exceeding the future net cash flows expected to be generated by theseintangible assets acquired through the X-spine acquisition. See Note 4 to the consolidated financial statements for more information regarding these charges. Restructuring expenses Restructuring expenses decreased $1.7 million to $3.0 million for the year ended December 31, 2018, from $4.7 million for the year-endedDecember 31, 2017. Restructuring costs were incurred by the Company related to our recapitalization and performance improvement measurements. Separation Related Expenses Separation related expenses decreased $0.3 million to $1.6 million for the year ended December 31, 2018, from $1.9 million for the year endedDecember 31, 2017. Separation related expenses consist severance and related benefit expenses for personnel reductions as part of our restructuring andclosure of our Dayton, Ohio facility, as well as severance paid to our former Chief Executive Officer. Non-cash Consulting Expense Non-cash consulting expense consists of non-cash expense associated with granting restricted stock and stock to directors and consultants. Non-cashconsulting expense was $0.1 million for the year ended December 31, 2018, remaining consistent to the $0.1 million for the year ended December 31, 2017. Interest Expense Interest expense is related to interest incurred on our debt instruments. Interest expense for the year ended December 31, 2018 decreased $4.6 millionto $10.1 million as compared to $14.7 million for the year ended December 31, 2017. The decrease in interest expense is due to the 24th and 25thamendments to the Prior Credit Agreement, resulting in lower effective interest rates on outstanding debt. Change in Warrant Derivative Liability For the year ended December 31, 2018, we recorded a gain in our non-cash warrant derivative liability of $0.1 million, and a gain in the year endedDecember 31, 2017 of $0.2 million were primarily driven by a change in the closing price of our common stock at December 31, 2018 and 2017, respectively.The liability is associated with the issuance of warrants as part of our prior convertible debt financing, our 2010 financing and our 2014 equity financingwhich contains certain provisions requiring the Company to record a change in the fair value of the warrant derivative liability from period to period. 52 December 31, 2018 2017 Cash and cash equivalents $6,797 $2,856 Accounts receivable, net 9,990 12,714 Inventories, net 17,301 22,423 Total current assets 34,677 39,699 Accounts payable 6,465 9,476 Accrued liabilities 5,150 15,845 Total current liabilities 12,051 25,818 Total working capital 22,626 13,881 Long-term debt, less issuance costs 77,939 137,962 Liquidity and Capital Resources Working Capital Since our inception, we have historically financed our operations through operating cash flows, as well as the private placement of equity securitiesand convertible debt, an equity credit facility, a debt facility, a common stock rights offering and other debt transactions. The following table highlights several key measures of our working capital performance, and debt levels (in thousands): Xtant has reduced its accounts payable from $9.5 million at December 31, 2017, to $6.5 million as of December 31, 2018. Accrued liabilities of $5.2million at December 31, 2018 decreased from $15.8 million at December 31, 2017 primarily due to the accumulation of accrued interest on long-term debt,the payment of which has been delayed or converted to equity as noted in recent amendments of the Company’s long-term debt agreements. Total liabilities as of December 31, 2018 include $77.9 million of long-term debt due to the lenders under our credit facility. Cash Flows Net cash provided by operating activities for the year ended December 31, 2018 was $1.2 million driven primarily from management of workingcapital. For the comparable period of 2017, net cash used in operating activities was $0.5 million. The improvement in cash provided by operating activitiesis the result of our restructuring efforts in 2017 to improve liquidity, convert receivables to cash and reduce payables and accrued liabilities. The amendmentsto our Prior Credit Agreement during 2018 to allow for the non-payment of then current interest decreased our accrued interest on long-term debt by $5.9million in the year ended December 31, 2018. Net cash used in investing activities for the year ended December 31, 2018 was $0.4 million, primarily representing purchases of property andequipment. Net cash used in investing activities for the year ended December 31, 2017 was $1.6 million, primarily representing purchases of property andequipment, partially offset by proceeds from the sale of fixed assets. Net cash provided by financing activities was $3.1 million for the year-ended December 31, 2018 due to $6.8 million in proceeds from a privateplacement, partially offset by $3.4 million in costs associated therewith and our debt conversion. 53 Second Amended and Restated Credit Agreement On March 29, 2019, we entered into a Second Amended and Restated Credit Agreement (the “Second Amended and Restated Credit Agreement”)with OrbiMed Royalty Opportunities II, LP and ROS Acquisition Offshore LP. (collectively, the “Investors”), which amended and restated the prior Amendedand Restated Credit Agreement dated as of July 27, 2015 among the parties thereto, and as subsequently amended through the Twenty-Fifth Amendment tothe Amended and Restated Credit Agreement, the “Prior Credit Agreement”). The Second Amended and Restated Credit Agreement amended the Prior Credit Agreement to provide that X-Spine may request term loans with theInvestors in an amount equal to the remaining commitment for additional delayed draw loans, which was approximately $2,200,000 as of the date of theSecond Amended and Restated Credit Agreement, and request additional term loans in an aggregate amount of up to $10,000,000, the amount of each loandraw to be subject to our production of a thirteen-week cash flow forecast that is approved by the Investors and which shows a projected cash balance for thefollowing two-week period of less than $1,500,000, as well as the satisfaction (or waiver in writing by each Investor) of conditions precedent, includingclosing certificate, delivery of budget, and other satisfactory documents. In addition, the Second Amended and Restated Credit Agreement provides that (i)no interest will accrue on the Loans under the Second Amended and Restated Credit Agreement from and after January 1, 2019 until March 31, 2020; (ii)beginning April 1, 2020 through the maturity date of the Second Amended and Restated Credit Agreement, interest payable in cash will accrue on the Loansunder the Credit Agreement at a rate per annum equal to the sum of (a) 10.00% plus (b) the higher of (x) the LIBO Rate (as such term is defined in the SecondAmended and Restated Credit Agreement) and (y) 2.3125%; (iii) the maturity date of the Loans is March 31, 2021; (iv) the Consolidated Senior LeverageRatio and Consolidated EBITDA (as such terms were defined in the Prior Credit Agreement) financial covenants were deleted and a new Revenue Base (assuch term is defined in the Second Amended and Restated Credit Agreement) financial covenant was added; and (v) the key person event default provisionwas revised to refer specifically to Kevin Brandt and Ron Berlin. Under the terms of the Prior Credit Agreement we were required to comply with a minimum liquidity covenant, a consolidated leverage ratiocovenant and a minimum consolidated EBITDA covenant. We were in compliance with all covenants under the Prior Credit Agreement as of December 31,2018. As of December 31, 2018, we had $55.8 million in borrowings outstanding under the Prior Credit Agreement and $2.2 million in unused availabilityunder the Prior Credit Agreement. As a result of the Second Amended and Restated Credit Agreement, as of March 29, 2019 we added an additional $10million in unused availability under our Credit Facility. Cash Requirements We believe that our December 31, 2018 cash and cash equivalents of $6.8 million, together with the subsequent availability of $10.0 million underour new Second Amended and Restated Credit Agreement, will be sufficient to meet our anticipated cash requirements through the end of March 2020.However, we may require additional funds to fund our future operations and business strategy. Accordingly, there is no assurance that we will not need orseek additional funding prior to such time. We may elect to raise additional funds even before we need them if market conditions for raising additionalcapital are favorable. We may seek to raise additional funds through various sources, such as equity and debt financings, additional debt restructurings orrefinancings, or through strategic collaborations and license agreements. We can give no assurances that we will be able to secure additional sources of fundsto support our operations, or if such funds are available to us, that such additional financing will be sufficient to meet our needs or on terms acceptable to us.This is particularly true if economic and market conditions deteriorate. To the extent that we raise additional capital through the sale of equity or convertible debt securities or the restructuring or refinancing of our debt,the interests of our current stockholders may be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of ourcurrent stockholders. If we issue preferred stock, it could affect the rights of our stockholders or reduce the value of our common stock. In particular, specificrights granted to future holders of preferred stock may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights,sinking fund provisions, and restrictions on our ability to merge with or sell our assets to a third party. Additional debt financing, if available, may involveagreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expendituresor declaring dividends. Prior to raising additional equity or debt financing, we must obtain the consent of the Investors, and no assurance can be providedthat the Investors would provide such consent, which could limit our ability to raise additional financing. Off Balance Sheet Arrangements We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition,changes in financial condition, revenues or expenses, results of operations, liquidity or capital expenditures or capital resources that are material to aninvestor in our shares. Recent Accounting Pronouncements Information regarding recent accounting pronouncements is included in Note 1 to the consolidated financial statements in “Item 8. FinancialStatements and Supplementary Data.” 54 Critical Accounting Estimates All of our significant accounting policies and estimates are described in Note 1 to the consolidated financial statements in “Item 8. FinancialStatements and Supplementary Data.” Certain of our more critical accounting estimates require the application of significant judgment by management inselecting the appropriate assumptions in determining the estimate. By their nature, these judgments are subject to an inherent degree of uncertainty. Wedevelop these judgments based on our historical experience, terms of existing contracts, our observance of trends in the industry, information provided byour customers, and information available from other outside sources, as appropriate. Different, reasonable estimates could have been used in the currentperiod. Additionally, changes in accounting estimates are reasonably likely to occur from period to period. Both of these factors could have a material impacton the presentation of our financial condition, changes in financial condition, or results of operations. We believe that the following financial estimates are both important to the portrayal of our financial condition and results of operations and requiresubjective or complex judgments. Further, we believe that the items discussed below are properly recorded in our financial statements for all periodspresented. Our management has discussed the development, selection, and disclosure of our most critical financial estimates with the Audit Committee of theBoard of Directors and with our independent auditors. The judgments about those financial estimates are based on information available as of the date of ourfinancial statements. Those financial estimates include: Goodwill and Intangible Assets Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill and intangible assets acquired in a purchasebusiness combination and determined to have indefinite useful lives are not amortized, instead they are tested for impairment annually and whenever eventsor circumstances indicate the carrying amount of the asset may not be recoverable. We conduct our impairment test on an annual basis and review theanalysis assumptions on a quarterly basis. We test goodwill for impairment at the reporting unit level, which is an operating segment or one level below anoperating segment, referred to as a component. A component of an operating segment is a reporting unit if the component constitutes a business for whichdiscrete financial information is available and segment management regularly reviews the operating results of that component. We chose December 31 to assess our annual goodwill for any impairment in order to closely align with the timing of our annual planning process.On an annual basis, or more frequently upon the occurrence of certain events, we test for goodwill impairment. In conducting the impairment test, we firstassessed qualitative factors to determine whether it was more likely than not that the fair value of a reporting unit was less than its carrying amount as a basisfor determining whether it was necessary to perform the two-step goodwill impairment test. If the qualitative step was not passed, we performed a two-stepimpairment test whereby in the first step, we would compare the fair value of the reporting unit with its carrying amount. If the carrying amount exceeded itsfair value, we performed the second step of the goodwill impairment test to determine the amount of impairment. The second step, measuring the impairmentloss, compared the implied fair value of the goodwill with the carrying value of the goodwill. Any excess of the goodwill carrying value over the implied fairvalue would be recognized as an impairment loss. In our evaluation of goodwill, we performed an assessment of qualitative factors to determine if it is more-likely-than-not that goodwill might beimpaired. We considered factors such as, but not limited to, macroeconomic conditions, industry and market considerations, and financial performance,including the planned revenue and earnings of X-spine. The results from the assessment and a Step 1 analysis allowed us to conclude that a further valuationof goodwill was necessary, as indicators of impairment existed as of December 31, 2018. As part of the Step 1 analysis, we updated the discounted cash flowanalysis used to determine our initial fair value as of December 31, 2018. Based on the results of the impairment test and analysis, we concluded that the fairvalue of the Company was less than its carrying amount. Based on the results of the impairment test and analysis, we concluded that a Step 2 goodwill impairment test was needed to determine the amountof impairment loss, if any. We engaged a third-party specialist to assist in the valuation. We compared the carrying value of the assets, including cash, andnon-interest-bearing liabilities to the derived enterprise value of the business. As a result, we recorded a non-cash goodwill impairment charge of $38.3million during the fourth quarter of 2018. The remaining Goodwill is valued at $3.2 million as of December 31, 2018. 55 During the fourth quarter of 2018, a few things changed in our business that led us to conclude that a goodwill impairment charge was appropriate.First, in connection with our annual planning process for 2019, we determined that the revenue growth rates for our fixation business likely would not beconsistent with the expectations on which our initial 2018 annual plan was built. Second, in connection with our annual planning process for 2019, weabandoned a new sales channel strategy that we had implemented in 2018 to build a direct sales force since we determined that the sales channel strategy wasnot reaping the benefits that we had originally thought it would. We also determined by the end of 2018 that our assumptions regarding the expansion of ourinternational business were inaccurate and likely would not prove out to be true in the near future in light of our business priorities, international regulatoryissues and anticipated funding requirements. Intangible assets consist of various patents with regards to processes for our products and intangible assets associated with the acquisition of X-spine. Given the level of impairment initially indicated by the Step 1 analysis, an ASC 360, Property, Plant and Equipment, test was performed on ouridentified intangible assets. As a result of the analysis, we recorded an impairment charge in 2018 of $9.8 million to Tradenames, Technology and CustomerRelationships based on the carrying amount exceeding the future net cash flows expected to be generated by these intangible assets. We also recorded animpairment charge in 2017 of $17.6 million related to Technology and Tradenames. Inventory Valuation Inventories are stated at the lower of cost or net realizable value. Cost is determined using the specific identification method and includes materials,labor and overhead. We calculate an inventory reserve for estimated obsolescence and excess inventory based on historical usage and sales, as well asassumptions about future demand for its products. A significant decrease in demand could result in an increase in the amount of excess inventory quantitieson hand. Additionally, our industry is characterized by regular new product development that could result in an increase in the amount of obsolete inventoryquantities on hand due to cannibalization of existing products. Our estimates for excess and obsolete inventory are reviewed and updated on a quarterlybasis. Our estimates of future product demand may prove to be inaccurate in which case we may be required to incur charges for excess and obsoleteinventory. Increases in the inventory reserves result in a corresponding expense, which is recorded to cost of sales. Total charges incurred to write down excess and obsolete inventory to net realizable value included in Cost of sales were approximately $4.6million and $4.0 million for the years ended December 31, 2018 and 2017. During the year ended December 31, 2018, due primarily to the significantdecrease in fixation sales, we changed our estimate for determining excess and obsolete inventory to include 100% of fixation products with quantity onhand greater than two years of sales which resulted in our excess and obsolete inventory reserve being much larger than in prior periods. In the future, if additional inventory write-downs are required, we would recognize additional cost of goods sold at the time of such determination.Regardless of changes in our estimates of future product demand, we do not increase the value of our inventory above its adjusted cost basis. Therefore,although we make every effort to ensure the accuracy of our forecasts of future product demand, significant unanticipated decreases in demand ortechnological developments could have a significant impact on the value of our inventory and our reported operating results. Instruments We deploy certain surgical instruments through various sales channels for use with purchased implants during surgical procedures. The instrumentsare classified as non-current assets within property and equipment and depreciated using the straight-line method over a five-year useful life. The net bookvalue of consigned surgical instruments was approximately $4.4 million and $6.6 million at December 31, 2018 and December 31, 2017, respectively. Wereview instruments for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Animpairment loss would be recognized when estimated future undiscounted cash flows relating to an asset are less than the asset’s carrying amount. Animpairment loss is measured as the amount by which the carrying amount of an asset exceeds its fair value. An impairment charge of $1.6 million wasrecorded for the year ended December 31, 2017 for instruments on consignment which were determined not to be recoverable. No impairment was recordedfor the year ended December 31, 2018. 56 Accounts Receivable and Allowances Accounts receivable represents amounts due from customers for which revenue has been recognized. Normal terms on trade accounts receivable arenet 30 days and some customers are offered discounts for early pay. We perform credit evaluations when considered necessary, but generally do not requirecollateral to extend credit. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing receivables. We determine theallowance based on factors such as historical collection experience, customer’s current creditworthiness, customer concentration, age of accounts receivablebalance, general economic conditions that may affect a customer’s ability to pay, and management judgment. Actual customer collections could differ fromestimates. Account balances are charged to the allowance after all means of collection have been exhausted and the potential for recovery is consideredremote. Provisions to the allowance for doubtful accounts are charged to expense. We do not have any off-balance sheet credit exposure related to ourcustomers. Deterioration in the financial condition of any key customer or a significant slowdown in the economy could have a material negative impact on ourability to collect a portion or all of our accounts receivable. We believe that an analysis of historical trends and our current knowledge of potential collectionproblems provide us with sufficient information to establish a reasonable estimate for an allowance for doubtful accounts. However, since we cannot predictwith certainty future changes in the financial stability of our customers, our actual future losses from uncollectible accounts may differ from our estimates. Inthe event we determined that a smaller or larger uncollectible accounts reserve is appropriate, we would record a credit or charge to sales and marketingexpense in the period that we made such a determination. Our allowance for doubtful accounts was $2.1 million at December 31, 2018 and 2017. Valuation of Deferred Tax Assets and Liabilities and Uncertain Tax Positions We account for income taxes in accordance with provisions which set forth an asset and liability approach that requires the recognition of deferredtax assets and deferred tax liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases ofassets and liabilities. Realization of deferred tax assets in each taxable jurisdiction is dependent on our ability to generate future taxable income sufficient torealize the benefits. Management evaluates deferred tax assets on an ongoing basis and provides valuation allowances to reduce net deferred tax assets to theamount that is more likely than not to be realized. The ultimate realization of deferred tax assets is dependent upon the existence, or generation, of taxable income in the periods when those temporarydifferences and net operating loss carryovers are deductible. Management considers the scheduled reversal of deferred tax liabilities, taxes paid in carryoveryears, projected future taxable income, available tax planning strategies, and other factors in making this assessment. Based on available evidence,management does not believe it is more likely than not that all of the deferred tax assets will be realized. Accordingly, we have established a valuationallowance equal to the net realizable deferred tax assets. Our valuation allowance balances totaled $29.9 million and $22.6 million at December 31, 2018 and2017, respectively. The valuation allowance increased by $7.3 million in 2018 and increased by $6.4 million in 2017. As a multinational corporation, we are subject to taxation in many jurisdictions and the calculation of our tax liabilities involves dealing withuncertainties in the application of complex tax laws and regulations in various taxing jurisdictions. In accordance with ASC 740, Income Taxes, we recognizethe tax effects of an income tax position only if they are “more-likely-than-not” to be sustained based solely on the technical merits as of the reporting date. Ifwe ultimately determine that the payment of these liabilities will be unnecessary, we will reverse the liability and recognize a tax benefit in the period inwhich we determine the liability no longer applies. Conversely, we record additional tax charges in a period in which we determine that a recorded taxliability is less than we expect the ultimate assessment to be. The company has not recorded any uncertain tax positions for the years ended December 31,2018 and December 31, 2017. 57 Under the Tax Reform Act of 1986, as amended, the amounts of and benefits from net operating loss carryovers and research and developmentcredits may be impaired or limited in certain circumstances. Events which cause limitations in the amount of net operating losses that we may utilize in anyone year include, but are not limited to, a cumulative ownership change of more than 50%, as defined, over a three-year period. We do not believe that suchan ownership change has occurred in 2018 and 2017. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”), was signed into legislation. As a result of the lower enacted corporate tax rate, wehave remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. Theamount recorded at December 31, 2017 related to the remeasurement of our deferred tax balance was $11.8 million, that was fully offset by a correspondingdecrease to the valuation allowance. On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”), was issued to address the application of U.S. GAAP in situations when aregistrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accountingfor certain income tax effects of the Act. In accordance with SAB 118, we have provisionally determined that there is no tax deferred tax benefit or expensewith respect to the remeasurement of certain deferred tax assets and liabilities due to the full valuation allowance against net deferred tax assets. TheCompany analyzed certain aspects of the Act further and refined its calculations during 2018. The Company has completed their analysis of the impact of theTax Act at December 31, 2018 and has incorporated it into the current year provision. The most significant impact as a result of the Act, beginning in tax year2018, is the limitation placed on the deductibility of interest expense. Going Concern The accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern which contemplates therealization of assets and liquidation of liabilities in the normal course of business and do not include any adjustments relating to the recoverability orclassification of assets or the amounts of liabilities that might result from the outcome of these uncertainties. Our ability to continue as a going concern,realize the carrying value of our assets and discharge our liabilities in the ordinary course of business is dependent upon a number of factors, including, thelevel and timing of future revenues and expenditures; development, commercialization and market acceptance of our products; competing technologies andmarket developments; regulatory requirements and delays; ability to attract and retain key personnel; and pending litigation. Management’s evaluation of going concern was conducted as part of the multiple discussions with the review by the Board of Directors of our 2019Annual Operating Plan. The Company and OrbiMed have entered into a Second Amended and Restated Credit Agreement and commitment for up to anadditional $10 million in debt capital. Management believes these actions, along with the $16.7 million of cash and accounts receivable on the balance sheetas of December 31, 2018, will enable the Company to continue as a going concern through the end of March 2020. Although we recently increased availability under our Second Amended and Restated Credit Agreement we still believe we may require additionalfunds to fund our future operations and business strategy. Accordingly, there is no assurance that we will not need or seek additional funding. We may electto raise additional funds even before we need them if market conditions for raising additional capital are favorable. We may seek to raise additional fundsthrough various sources, such as equity and debt financings, additional debt restructurings or refinancings, or through strategic collaborations and licenseagreements. We can give no assurances that we will be able to secure additional sources of funds to support our operations, or if such funds are available tous, that such additional financing will be sufficient to meet our needs or on terms acceptable to us. This is particularly true if economic and market conditionsdeteriorate. Any failure by us to raise additional funds on terms favorable to us, or at all, could result in our inability to pay our expenses as they come due,limit our ability to expand our business operations, and harm our overall business prospects. If adequate funds are not otherwise available, we would berequired to curtail operations significantly, including reducing our sales and marketing expenses which could negatively impact product sales and we couldeven be required to cease operations, liquidate our assets and possibly seek bankruptcy protection. 58 Item 7A.Quantitative and Qualitative Disclosures About Market Risk This Item 7A is inapplicable to Xtant as a smaller reporting company.

(“X-spine”), an Ohio corporation, (Xtant Medical Inc., Bacterin and X-spine are jointlyreferred to herein as “Xtant” or the “Company”). All intercompany balances and transactions have been eliminated in consolidation. Xtant products serve thecombined specialized needs of orthopedic and neurological surgeons, including orthobiologics for the promotion of bone healing, implants andinstrumentation for the treatment of spinal disease, tissue grafts for the treatment of orthopedic disorders to promote healing following spine, cranial and footsurgeries and the development, manufacturing and sale of medical devices for use in orthopedic spinal surgeries. The markets in which the Company competes are highly competitive and rapidly changing. Significant technological advances, changes incustomer requirements, or the emergence of competitive products with new capabilities or technologies could adversely affect the Company’s operatingresults. The Company’s business could be harmed by a decline in demand for, or in the prices of, its products or as a result of, among other factors, any changein pricing or distribution methods, increased price competition, changes in government regulations or a failure by the Company to keep up withtechnological change. Further, a decline in available donors could have an adverse impact on our business. As described in more detail below, effective as of February 13, 2018, the Company effected a 1-for-12 reverse split of its common stock (the “ReverseStock Split”). The Reverse Stock Split is reflected in the share amounts in all periods presented in this report. At December 31, 2018, the Company had cash on hand balances of $6.8 million, and accumulated deficit of $215 million and has incurred significantlosses in the current and prior periods. Management’s evaluation of going concern was conducted as part of the multiple discussions with the Xtant Board of Directors’ review of theAnnual Operating Plan. The Company and OrbiMed have entered into a Second Amended and Restated Credit Agreement and commitment for up to anadditional $10 million in debt capital. Management believes these actions along with the $16.7 million of cash and accounts receivable on the balance sheetas of December 31, 2018 will enable the Company to continue as a going concern through the end of March 2020. Corporate Restructuring Restructuring Agreement On January 11, 2018, we entered into a Restructuring and Exchange Agreement (the “Restructuring Agreement”) with ROS Acquisition Offshore LP,OrbiMed Royalty Opportunities II, LP (collectively referred to herein as the “Investors”), Bruce Fund, Inc., Park West Partners International, Limited(“PWPI”), Park West Investors Master Fund, Limited (“PWIMF”), and Telemetry Securities, L.L.C., and with the Investors, are collectively referred to hereinas the “Holders”. Pursuant to the Restructuring Agreement, and following the execution of the Sixth Amendment to the 2017 Notes, described in the “Debt” and“Equity” sections below, on January 17, 2018, the Investors converted the 6.00% convertible senior unsecured notes due 2021, plus accrued and unpaidinterest, at the $9.11 per share conversion rate originally provided thereunder (the “2017 Notes”), into 189,645 shares of our common stock. 66 On February 14, 2018, after giving effect to the Reverse Stock Split (described below), $70.3 million aggregate principal amount of our thenoutstanding 6.00% convertible senior unsecured notes due 2021 held by the Holders (the “Remaining Notes”), plus accrued and unpaid interest, wereexchanged for newly-issued shares of our common stock at an exchange rate of 138.8889 shares per $1,000 principal amount of the Remaining Notes, for anexchange price of $7.20 per share (the “Notes Exchange”). This resulted in the issuance of 10,401,309 shares of our common stock to the Holders and theInvestors acquiring an approximately 70% controlling interest in our outstanding shares of common stock. Upon the completion of the Notes Exchange, alloutstanding obligations under our convertible senior secured notes were satisfied in full and the Indentures governing such notes were discharged. Pursuant to the terms of the Restructuring Agreement, we commenced a rights offering to allow our stockholders as of April 27, 2018 record date topurchase up to an aggregate of 1,137,515 shares of our common stock at a subscription price of $7.20 per share. The rights offering expired on June 18, 2018.We issued 129 shares of common stock in the rights offering and received $0.9 thousand gross proceeds. Amended and Restated Certificate of Incorporation On February 13, 2018, following a special meeting of our stockholders, we filed with the Secretary of State of the State of Delaware a Certificate ofAmendment to our Certificate of Incorporation (the “Certificate Amendment”). The Certificate Amendment amended and restated our Certificate ofIncorporation (the “Charter”) to, among other things: ●effect the Reverse Stock Split; ●after giving effect to the Reverse Stock Split, decrease the number of authorized shares of common stock available for issuance from 95,000,000 to50,000,000 and increase the number of authorized shares of preferred stock available for issuance from 5,000,000 to 10,000,000; ●authorize the Board of Directors (“Board”) to increase or decrease the number of shares of any series of our capital stock, provided that such increase ordecrease does not exceed the number of authorized shares or be less than the number of shares then outstanding; ●authorize the Board to issue new series of preferred stock without approval of the holders of common stock or other series of preferred stock, with suchpowers, preferences and rights as may be determined by the Board; ●authorize a majority of the Board to fix the number of our directors; ●indemnify the members of the Board to the fullest extent permitted by law; ●remove the classification of the Board to require all directors to be elected annually; ●provide that special meetings of our stockholders may only be called by the Board, the chairman of the Board or our chief executive officer; ●provide that no stockholder will be permitted cumulative voting at any election of directors; ●elect not to be governed by Section 203 of the Delaware General Corporation Law (the “DGCL”); ●elect the Court of Chancery of the State of Delaware to be the exclusive forum for any derivative action or proceeding brought on our behalf, anyaction asserting a breach of a fiduciary duty owed by any of our directors, officers or other employees, any action under the DGCL, our Charter orbylaws or any actions governed by the internal affairs doctrine; and ●require the vote of at least two-thirds of the voting power of the then outstanding shares of our capital stock to amend or repeal certain provisions ofour Charter. 67 The Reverse Stock Split became effective as of 5:00 p.m. Eastern Time on February 13, 2018, and our common stock began trading on a split-adjusted basis when the market opened on February 14, 2018. Upon the effectiveness of the Reverse Stock Split, every 12 shares of our issued andoutstanding common stock automatically converted into one share of common stock, without any change in the par value per share. In addition, aproportionate adjustment was made to the per share exercise or conversion price and the number of shares issuable upon the exercise of all of our outstandingstock options and convertible securities to purchase shares of common stock and the number of shares underlying restricted stock awards and reserved forissuance pursuant to our equity incentive compensation plan. Any fraction of a share of common stock that would otherwise have resulted from the ReverseStock Split was rounded down to the nearest whole share. All share and per share amounts have been retroactively restated to reflect the Reverse Stock Split. Private Placement SPA On February 14, 2018, we entered into a Securities Purchase Agreement (the “Private Placement SPA”) with the Investors pursuant to which theInvestors purchased from us an aggregate of 945,819 shares of our common stock, at a price of $7.20 per share, for aggregate proceeds of $6.8 million. Investor Rights Agreement Effective February 14, 2018, we entered into an Investor Rights Agreement (the “Investor Rights Agreement”) with the Holders. Under the InvestorRights Agreement, the Investors are permitted to nominate a majority of our directors and designate the chairperson of the Board at subsequent annualmeetings, as long as the Investors maintain an ownership threshold in the Company of at least 40% of our then outstanding common stock (the “OwnershipThreshold”). If the Investors are unable to maintain the Ownership Threshold, the Investor Rights Agreement contemplates a reduction of nomination rightscommensurate with their ownership interests. For so long as the Ownership Threshold is met, we must obtain the approval of the Investors to proceed with the following actions: (i) issue newsecurities; (ii) incur over $0.25 million of debt in a fiscal year; (iii) sell or transfer over $0.25 million of our assets or businesses or our subsidiaries in a fiscalyear; (iv) acquire over $0.25 million of assets or properties in a fiscal year; (v) make capital expenditures over $0.125 million individually, or $1.5 million inthe aggregate during a fiscal year; (vi) approve our annual budget; (vii) hire or terminate our chief executive officer; (viii) appoint or remove the chairpersonof the Board; and (ix) make, loans to, investments in, or purchase, or permit any subsidiary to purchase, any stock or other securities in another entity inexcess of $0.25 million in a fiscal year. As long as the Ownership Threshold is met, we may not increase the size of the Board beyond seven directors withoutthe approval of a majority of the directors nominated by the Investors. The Investor Rights Agreement grants the Holders the right to purchase from us a pro rata amount of any new securities that we may propose to issueand sell. The Investor Rights Agreement may be terminated (a) upon the mutual written agreement of all the parties, (b) upon written notice of the Companyor an Investor, if such Investor’s ownership percentage of our then outstanding common stock is less than 10%, or (c) upon written notice by the Investors.PWPI and PWIMF’s right to purchase from us a pro rata amount of any new securities will also terminate at such time as their aggregate ownership percentageof our then outstanding common stock is less than 8.5%. Registration Rights Agreement Effective February 14, 2018, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Holders. TheRegistration Rights Agreement requires us to, among other things, file with the U. S. Securities and Exchange Commission (“SEC”) a shelf registrationstatement within 90 days of the date of the Registration Rights Agreement covering the resale, from time to time, of our common stock issued. Thisregistration statement became effective on June 4, 2018. 68 Second Amended and Restated Bylaws On February 14, 2018, we amended and restated our current bylaws by adopting the Second Amended and Restated Bylaws of the Company (the“Amended Bylaws”). The Amended Bylaws amended our existing bylaws to, among other things: ●provide for annual and special meetings of stockholders to be held through remote communications; ●provide for the election of any directors not elected at an annual meeting of stockholders to be elected at a special meeting of stockholders; ●declassify the Board into one group of directors that will hold office until the subsequent annual meeting of stockholders and until the election andqualification of such directors’ respective successors; ●provide for the filling of a new directorship or director vacancy by the affirmative vote of the holders of a majority of the voting power of our shares ofstock; ●allow for a majority of the Board present to adjourn a Board meeting if a quorum is not met; ●unless otherwise restricted in the Amended Bylaws or our Charter, provide the Board with the authority to fix the compensation of directors, includingwithout limitation, compensation for services as members of Board committees; ●allow us to enter into an agreement with a stockholder to restrict the transfer of shares held by such stockholder in any manner not prohibited by theDGCL; and ●allow the Board to declare dividends on our capital stock, subject to any provisions of our Charter and applicable law. Concentrations and Credit Risk The Company’s accounts receivables are from a variety of health care organizations and distributors throughout the world. No single customeraccounted for more than 10% of revenue or accounts receivable in the fiscal years 2018 or 2017. The Company provides for uncollectible amounts whenspecific credit issues arise. Management believes that all significant credit risks have been identified at December 31, 2018. Use of Estimates The preparation of the financial statements requires management of the Company to make a number of estimates and assumptions relating to thereported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amountsof revenue and expenses during the period. Significant estimates include the carrying amount of property and equipment (including surgical instruments),goodwill, and intangible assets and liabilities; valuation allowances for trade receivables, inventory valuation, and deferred income tax assets and liabilities;valuation of the warrant derivative liability; inventory and estimates for the fair value of stock options grants and other equity awards upon which theCompany determines stock-based compensation expense. Actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity date of three months or less to be cash equivalents. Cashequivalents are recorded at cost, which approximates market value. At times the Company maintains deposits in financial institutions in excess of federallyinsured limits. 69 Trade Accounts Receivable Accounts receivable represents amounts due from customers for which revenue has been recognized. Normal terms on trade accounts receivable arenet 30 days and some customers are offered discounts for early pay. The Company performs credit evaluations when considered necessary, but generally doesnot require collateral to extend credit. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing receivables.The Company determines the allowance based on factors such as historical collection experience, customer’s current creditworthiness, customerconcentration, age of accounts receivable balance, general economic conditions that may affect a customer’s ability to pay, and management judgment.Actual customer collections could differ from estimates. Account balances are charged to the allowance after all means of collection have been exhausted andthe potential for recovery is considered remote. Provisions to the allowance for doubtful accounts are charged to expense. The Company does not have anyoff-balance sheet credit exposure related to its customers. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using the specific identification method and includes materials,labor and overhead. The Company calculates an inventory reserve for estimated obsolescence and excess inventory based on historical usage and sales, aswell as assumptions about future demand for its products. These estimates for excess and obsolete inventory are reviewed and updated on a quarterly basis.Increases in the inventory reserves result in a corresponding expense, which is recorded to cost of sales. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimateduseful lives of the assets, generally three to seven years for computers and equipment and five years for surgical instruments. Leasehold improvements aredepreciated over the shorter of their estimated useful life or the remaining term of the lease. Repairs and maintenance are expensed as incurred. Intangible Assets Intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values and reviewedfor impairment whenever events or circumstances indicate their carrying amount may not be recoverable. Intangible assets include trademarks and patentsand include costs to acquire and protect Company patents. Intangible assets are carried at cost less accumulated amortization. The Company amortizes theseassets on a straight-line basis over their estimated useful lives. In 2015 with the acquisition of X-spine, the Company established a fair value for the technology, tradenames and intangible assets which wasdetermined based upon a “relief from royalty” approach. The amortization of these assets is consistent with the valuation method used to establish their fairvalue which in turn was based on the assets’ future cash flow. Other Assets Other Assets consist of the short-term and the long-term portion of prepaid expenses and security deposits. Long-Lived Assets Long-lived assets, including intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carryingamount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset tofuture net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by theamount by which the carrying amount of the assets exceeds the estimated fair value of the assets. 70 Goodwill Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill and intangible assets acquired in a purchasebusiness combination and determined to have indefinite useful lives are not amortized, instead they are tested for impairment at least annually and wheneverevents or circumstances indicate the carrying amount of the asset may not be recoverable. The Company conducts its impairment test on an annual basis andwill review the analysis assumptions on a quarterly basis. We test goodwill for impairment at the reporting unit level, which is an operating segment or onelevel below an operating segment, referred to as a component. A component of an operating segment is a reporting unit if the component constitutes abusiness for which discrete financial information is available and segment management regularly reviews the operating results of that component. Revenue Recognition The Company adopted the provisions of Accounting Standards Update (“ASU”) No. 2014-09, Topic 606, Revenue from Contracts with Customers,effective January 1, 2018. This new accounting standard outlines a single comprehensive model used in accounting for revenue arising from contracts withcustomers. This standard supersedes existing revenue recognition requirements and eliminates most industry specific guidance from GAAP. The coreprinciple of the new accounting standard is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflectsthe consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the adoption of this new accounting standardresulted in increased disclosure, including qualitative and quantitative disclosures about the nature, amount, timing and uncertainty of revenue and cashflows arising from contracts with customers. Adoption Impact Given that our revenue recognition has remained generally the same as in prior years, the Company has elected the modified retrospective method ofadoption. On January 1, 2018, we analyzed contracts that were not completed as of adoption date. The cumulative effect of initially applying ASC 606 wouldhave been an adjustment to decrease the opening balance of retained earnings by $24 thousand as of January 1, 2018. Due to the amount being de minimis,no adjustment was recorded. In addition, the Company determined that there is a de minimis difference in 2018 revenues under ASC 606 versus the previousguidance. Disaggregation of Revenue The Company operates in one reportable segment with our net revenue derived primarily from the sale of orthobiologics and spinal implant productsacross North America, Europe, Asia Pacific and Latin America. Sales are reported net of returns. No rebates, group purchasing organization fees or othercustomer allowances are present, and so are not relevant to net revenue determination. The following table presents revenues from these product lines for theyear ended December 31, 2018: Year-Ended Percentage of December 31, 2018 Total Revenue Orthobiologics $48,984 68%Spinal implant 22,830 31%Other revenue 389 1%Total revenue $72,203 100% In the United States, we generate most of our revenue from independent commissioned sales agents. We consign our orthobiologics products tohospitals and consign or loan our spinal implant sets to the independent sales agents. The spinal implant sets typically contain the instruments, disposables,and spinal implants required to complete a surgery. Consigned sets are managed by the sales agent to service hospitals that are high volume users for multipleprocedures. We ship replacement inventory to independent sales agents to replace the consigned inventory used in surgeries. Loaned sets are returned to theCompany’s distribution center, replenished, and made available to sales agents for the next surgical procedure. For each surgical procedure, the sales agent reports use of the product by the hospital and, as soon as practicable thereafter, ensures that the hospitalprovides a purchase order to the Company. Upon receipt of the hospital purchase order, the Company invoices the hospital and revenue is recognized. Additionally, the Company sells product directly to domestic and international stocking resellers and private label resellers. Upon receipt andacceptance of a purchase order from a stocking reseller, the Company ships product and invoices the reseller. We recognize revenue when the products areshipped, and the transfer of title and risk of loss occurs. There is generally no customer acceptance or other condition that prevents us from recognizingrevenue in accordance with the delivery terms for these sales transactions. 71 The following table presents revenues from these sales channels for the year-ended December 31, 2018 (in thousands): Year-Ended Percentage of December 31, 2018 Total Revenue Independent agents $63,063 87%Direct sales 8,751 12%Other revenue 389 1%Total revenue $72,203 100% Performance Obligations The Company’s contracts do not include a right of acceptance or a right to cancel, therefore our process for recognizing revenue does not require anevaluation of whether acceptance is received or a right to cancel has expired. Further, the Company does not incur upfront costs or exclusivity fees inconjunction with entering into a customer contract. The Company’s customer contracts do not provide for percentage of completion performance measures orcontingent consideration. In the normal course of business, the Company accepts returns of product that have not been implanted. Product returns are not material to theCompany’s consolidated statements of operations. The Company accounts for shipping and handling activities as a fulfillment cost rather than a separateperformance obligation. The Company’s policy is to record revenue net of any applicable sales, use, or excise taxes. Payment terms are generally net 30 daysfrom invoice date and some customers are offered discounts for early pay. Contract Assets and Liabilities The Company does not have deferred or unearned revenue arrangements with its customers that would give rise to contract liabilities. The Companyrecognizes sales commissions as incurred because the amortization period is less than one year. Additionally, the Company does not recognize unbilledreceivables or progress payments to be billed that would result in a contract asset. All pricing and agreements are completed based on the contractedindividual unit price; no other methods of determining price are allowed within the Company’s sales agreements. Therefore, no contract assets or contractliabilities are recorded in our consolidated balance sheets as of December 31, 2018. Research and Development Research and development costs, which are principally related to internal costs for the development of new products are expensed as incurred. Net Loss Per Share Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding. Shares issued during theperiod and shares reacquired during the period are weighted for the portion of the period that they were outstanding. Diluted net loss per share is computed ina manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares outstanding during the period, whichinclude the assumed exercise of stock options and warrants using the treasury stock method. Diluted net loss per share was the same as basic net loss per sharefor the years ended December 31, 2018 and 2017, as shares issuable upon the exercise of stock options and warrants were anti-dilutive as a result of the netlosses incurred for those periods. Dilutive loss per share are not reported as their effects of including 2,207,567 and 587,382 outstanding stock options andwarrants for the years ended December 31, 2018 and 2017, respectively, are anti-dilutive. 72 Fair Value of Financial Instruments The carrying values of financial instruments, including trade accounts receivable, accounts payable, accrued liabilities and long-term debt,approximate their fair values based on terms and related interest rates. The Company follows a framework for measuring fair value. The framework provides a fair value hierarchy that prioritizes the inputs to valuationtechniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities(Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets. Level 2: Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observablefor the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair valuemeasurement. During the years ended December 31, 2018 and 2017, there was no reclassification in financial assets or liabilities between Level 1, 2 or 3categories. The following table sets forth by level, within the fair value hierarchy, our liabilities as of December 31, 2018 and 2017 that are measured at fairvalue on a recurring basis (in thousands): Warrant derivative liability As ofDecember 31, 2018 As ofDecember 31, 2017 Level 1 - - Level 2 - - Level 3 $10 $131 The valuation technique used to measure fair value of the warrant liability is based on a lattice valuation model and significant assumptions andinputs determined by us (See Note 8, “Warrants” below). Level 3 Changes The following is a reconciliation of the beginning and ending balances for liabilities measured at fair value on a recurring basis using significantunobservable inputs (Level 3) during the years ended December 31, 2018 and 2017 (in thousands): Warrant derivative liability Balance at January 1, 2017 $334 Gain recognized in earnings (203)Balance at January 1, 2018 $131 Gain recognized in earnings (121)Balance at December 31, 2018 $10 During the year ended December 31, 2018, the Company did not change any of the valuation techniques used to measure its liabilities at fair value. 73 Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use (“ROU”) asset and leaseliability on their balance sheet for all leases with terms beyond 12 months. The new standard also requires enhanced disclosures that will provide moretransparency and information to financial statement users about our lease portfolio. The distinction between operating and finance leases will continue toexist under the new standard. Additionally, the recognition and measurement of operating and finance lease expenses and cash flows will not changesignificantly from current treatment. For finance leases, lessees will continue to recognize interest expense on the lease liability using the effective yieldmethod, while the right-of-use asset will be amortized on a straight-line basis. For operating leases, expense will be recognized on a straight-line basis,consistent with the previous standard. We will adopt this ASU on January 1, 2019 using the modified retrospective approach and will not restate comparative periods. We are substantiallycomplete with our implementation plan. We plan to elect the transition package of three practical expedients permitted within the standard. In accordancewith the package of practical expedients, we will not reassess initial direct costs, lease classification, or whether our contracts contain or are leases. Based onour lease portfolio as of December 31, 2018, we plan to recognize an operating lease liability and related right-of-use asset on our balance sheet ofapproximately $3.0 million, which represents the present value of our future minimum lease payments related to operating leases. We do not anticipatematerial changes to our consolidated statement of operations or our consolidated statement of cash flows. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit losses: Measurement of Credit Losses on Financial Instruments, whichamends certain provisions of ASC 326, Financial Instruments-Credit Loss. The ASU changes the impairment model for most financial assets and certain otherinstruments. For trade and other receivables, held to maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowances for losses. The ASU is effective for annual reporting periodsbeginning after December 15, 2019, including interim periods within those annual periods, and will be applied as a cumulative effect adjustment to retainedearnings as of the beginning of the first reporting period for which the guidance is effective. We currently do not expect that the adoption of these provisionswill have a material effect on our consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, Stock Compensation (Topic 718), which amends the current standard. Specifically, the newstandard expands the scope of Topic 718 to include share-based payment awards to non-employees. Additionally, the ASU expands and amends the currentstandard to include and realign consistent with the changes to revenue standard Topic 606. Management expects that the adoption of this new standard willqualitatively impact the Company’s financial reporting. See further information in the Stock-Based Compensation of the management disclosure sectionbelow. In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), to simplify theaccounting for goodwill impairment. The update removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Agoodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.The ASU is effective for annual reporting periods beginning after December 15, 2019, but early adoption is permitted. We are currently evaluating thisupdate to determine the full impact of its adoption but do not expect this accounting standards update to have a material impact on our consolidatedfinancial position, results of operations or cash flows. Reclassification Certain prior year amounts have been reclassified to conform with current year presentation. 74 (2)Inventories Inventories consist of the following (in thousands): December 31, 2018 December 31, 2017 Raw materials $4,136 $4,277 Work in process 949 1,515 Finished goods 24,618 24,342 Gross inventories 29,703 30,134 Reserve for obsolescence (12,402) (7,711) $17,301 $22,423 The Company provides implants and biologic inventory on consignment through its various sales channels to logistically place the inventory nearthe anticipated surgical location. Consigned inventory was approximately $8.8 million and $12.0 million at December 31, 2018 and December 31, 2017,respectively. (3)Property and Equipment, Net Property and equipment, net are as follows (in thousands): December 31, 2018 December 31, 2017 Equipment $4,145 $4,471 Computer equipment 481 489 Computer software 570 524 Furniture and fixtures 164 215 Leasehold improvements 3,941 4,030 Vehicles 10 10 Surgical instruments 10,772 11,461 Total cost 20,083 21,201 Less: accumulated depreciation (12,909) (11,288) $7,174 $9,913 The Company deploys certain surgical instruments through its various sales channels for use with purchased implants during surgical procedures.The instruments are classified as non-current assets within property and equipment and depreciated using the straight-line method over a five-year useful life.The net book value of consigned surgical instruments was approximately $4.4 million and $6.6 million at December 31, 2018 and December 31, 2017,respectively. An impairment charge of $1.6 million was recorded for the year ended December 31, 2017 for instruments on consignment which weredetermined not to be recoverable. No impairment was recorded for the year ended December 31, 2018. Depreciation expense related to property and equipment, including property under capital lease, for the years ended 2018 and 2017 was $3.2 millionand $3.8 million, respectively. The Company leases certain equipment under capital leases. For financial reporting purposes, minimum lease payments relating to the assets havebeen capitalized. As of December 31, 2018, the Company has recorded $1.6 million gross capital lease assets within Equipment, and $0.9 million ofaccumulated depreciation. 75 (4)Goodwill and Intangible Assets Goodwill represents the excess of costs over fair value of assets on businesses acquired associated with the acquisition of X-spine. During the fourth quarter of 2018, a few things changed in our business that led us to conclude that a goodwill impairment charge was appropriate.First, in connection with our annual planning process for 2019, we determined that the revenue growth rates for our fixation business likely would not beconsistent with the expectations on which our initial 2018 annual plan was built. Second, in connection with our annual planning process for 2019, wecurtailed a new sales channel strategy that we had implemented in 2018 to build a direct sales force since we determined that the sales channel strategy wasnot generating the benefits that we had originally thought it would. We also determined by the end of 2018 that our assumptions regarding the expansion ofour international business were inaccurate and likely would not prove out to be true in the near future in light of our business priorities, internationalregulatory issues and anticipated funding requirements. In its evaluation of goodwill, the Company performs an assessment of qualitative factors to determine if it is more-likely-than-not that goodwillmight be impaired. We considered factors such as, but not limited to, macroeconomic conditions, industry and market considerations, and financialperformance, including the planned revenue and earnings of X-spine. The results from the assessment and a Step 1 analysis allowed the Company to concludethat a further valuation of goodwill was necessary, as indicators of impairment existed as of December 31, 2018. As part of the Step 1 analysis, we updated thediscounted cash flow analysis used to determine the Company’s initial fair value as of December 31, 2018. Based on the results of the impairment test andanalysis, we concluded that the fair value of the Company was less than its carrying amount. Based on the results of the impairment test and analysis, we concluded that a Step 2 goodwill impairment test was needed to determine the amountof impairment loss, if any. We engaged a third-party specialist to assist in the valuation. We compared the carrying value of the assets, including cash, andnon-interest-bearing liabilities to the derived enterprise value of the business. As a result, we recorded a non-cash goodwill impairment charge of $38.3million. The remaining Goodwill is valued at $3.2 million as of December 31, 2018. Intangible assets consist of various patents with regards to processes for our products and intangible assets associated with the acquisition of X-spine. Given the level of impairment initially indicated by the Step 1 analysis, an ASC 360, Property, Plant and Equipment, test was performed on theCompany’s identified intangible assets. As a result of the analysis, the Company recorded an impairment charge of $9.8 million to its intangible assets. The following table sets forth information regarding intangible assets (in thousands): December 31, 2018 December 31, 2017 Patents $847 $847 Acquisition related intangibles: Technology - 13,789 Customer relationships - 9,911 Tradename - 1,867 Non-compete - 41 Accumulated amortization (274) (12,629)Net carrying value $573 $13,826 Aggregate amortization expense: $2,539 $4,629 The following is a summary of estimated future amortization expense for intangible assets as of December 31, 2018 (in thousands): 2019 $56 2020 56 2021 55 2022 54 2023 53 Thereafter 299 Total $573 The Company recorded the impairment charge in 2018 of $9.8 million to Tradenames, Technology and Customer Relationships and in 2017 of$17.6 million related to Technology and Tradenames based on the carrying amount exceeding the future net cash flows expected to be generated by theseintangible assets. 76 (5)Accrued Liabilities Accrued liabilities consist of the following (in thousands): December 31, 2018 December 31, 2017 Accrued interest payable $- $10,835 Wages/commissions payable 3,332 2,831 Accrued stock compensation - 120 Other accrued liabilities 1,818 2,059 Accrued Liabilities $5,150 $15,845 (6)Debt Convertible Note Indenture During the first quarter of 2018 in connection with our Restructuring, all of the outstanding 6.00% convertible senior unsecured notes due 2021were converted into shares of our common stock and the Indenture governing such notes was discharged. Twenty-Second Amendment to the Prior Credit Agreement Effective January 30, 2018, the Company and Investors entered into the Twenty-Second Amendment to the Amended and Restated CreditAgreement dated July 27, 2015, which amended the Amended and Restated Credit Agreement by and between Bacterin and ROS Acquisition Offshore LP(collectively, the “Prior Credit Agreement” and the facility created under such agreement, the “Credit Facility”). This amendment further deferred theCompany’s accrued interest payment date for the fiscal quarters ended on December 31, 2016, March 31, 2017, June 30, 2017, September 30, 2017 andDecember 31, 2017 until February 28, 2018. Twenty-Third Amendment to the Prior Credit Agreement Effective February 14, 2018, the Company and Investors entered into the Twenty-Third Amendment to the Prior Credit Agreement, which furtheramended the Prior Credit Agreement and terms of the Credit Facility. As of this amendment, the interest payable has been carried forward and as modified, theinterest rate options within the Credit Facility are as follows: (a) through December 31, 2018, we will have the option at our sole discretion (i) to pay PIKInterest at LIBOR (as defined in the Credit Facility) plus 12% or (ii) pay cash interest at LIBOR plus 10%; (b) beginning January 1, 2019 through June 30,2019, we will have the option at our sole discretion to either (i) pay PIK Interest at LIBOR plus 15% or (ii) pay cash interest at LIBOR plus 10%; and (c)beginning July 1, 2019 through the maturity date of the Credit Facility, we will pay cash interest at LIBOR plus 10%. The amendment also reduced theprepayment or repayment fee under the Credit Facility to 1%. This amendment also modified the financial covenants in the Prior Credit Agreement, including removing the minimum revenue covenant,providing a minimum liquidity covenant, a consolidated leverage ratio covenant, and a minimum consolidated EBITDA covenant, all as defined in the PriorCredit Agreement. Twenty-Fourth Amendment to the Prior Credit Agreement On September 17, 2018, the Company and Investors entered into the Twenty-Fourth Amendment to the Prior Credit Agreement (the “24thAmendment”), which further amended the Prior Credit Agreement and terms of the Credit Facility, effective as of April 1, 2018. Under the terms of the 24thAmendment, no interest will be charged on the loans under the Credit Facility (the “Loans”) from April 1, 2018 until June 30, 2018. 77 Due to the interest rate relief provided by the 24th Amendment, the Company performed an assessment of the changes to the terms of the CreditFacility in accordance ASC 470, Debt. The Credit Facility was modified based on an evaluation of the present value of cash flows for the old and new debtinstruments. Given the modification, a new effective interest rate of 13.45% for the modified loan was calculated based on the carrying amount of the debtand the present value of the revised future cash flows. The modified interest rate is effective through the remaining life of the loan. Twenty-Fifth Amendment to the Prior Credit Agreement Also, on September 17, 2018, the Company and the Investors entered into the Twenty-Fifth Amendment to the Prior Credit Agreement (the “25thAmendment”), which further amended the Prior Credit Agreement and terms of the Credit Facility, effective as of August 1, 2018. Under the terms of the 25thAmendment: ●no interest will be charged on the Loans under the Credit Facility from July 1, 2018 until December 31, 2018; ●the Optional PIK Interest (as such term is defined in the Prior Credit Agreement) was decreased from 15% plus the LIBO Rate (as such term is defined inthe Prior Credit Agreement) to 10% plus the LIBO Rate, with a 2.3125% floor; ●a LIBO Rate floor of 2.3125% was added; and ●the fee due upon payment, prepayment or repayment of the principal amount of the Loans under the Credit Facility, whether on the maturity date orotherwise, was increased to 2% from 1% of the aggregate principal amount of such payment, prepayment or repayment. The Company issued warrants to purchase an aggregate of 1.2 million shares of Company common stock to the Investors, with an exercise price of$0.01 per share and an expiration date of August 1, 2028 (collectively, the “2018 Warrants”). The issuance of the 2018 Warrants occurred on September 17,2018 and was a condition to the effectiveness of the 25th Amendment. (See Note 8, “Warrants” below). Second Amended and Restated Credit Agreement On March 29, 2019, the Company and the Investors entered into a Second Amended and Restated Credit Agreement (the “Second Amended andRestated Credit Agreement”), which amended and restated the Prior Credit Agreement, as described under Note 16, “Subsequent Events” below. Under theSecond Amended and Restated Credit Agreement, X-Spine may continue to make requests for term loans in amounts equal to the remaining commitment foradditional delayed draw loans, which was approximately $2,200,000 as of the date of the Second Amended and Restated Credit Agreement, and may requestadditional term loans with the Investors in an aggregate amount of up to $10,000,000, with the amount of each loan draw to be subject to our production of athirteen-week cash flow forecast that is approved by the Investors and which shows a projected cash balance for the following two-week period of less than$1,500,000, as well as the satisfaction (or waiver in writing by each Investor) of conditions precedent, including closing certificate, delivery of budget, andother satisfactory documents. In addition, the Second Amended and Restated Credit Agreement amended the Prior Credit Agreement to provide that (i) nointerest will accrue on the Loans under the Second Amended and Restated Credit Agreement from and after January 1, 2019 until March 31, 2020; (ii)beginning April 1, 2020 through the maturity date of the Second Amended and Restated Credit Agreement, interest payable in cash will accrue on the Loansunder the Credit Agreement at a rate per annum equal to the sum of (a) 10.00% plus (b) the higher of (x) the LIBO Rate (as such term is defined in the SecondAmended and Restated Credit Agreement) and (y) 2.3125%; (iii) the maturity date of the Loans is March 31, 2021; (iv) the Consolidated Senior LeverageRatio and Consolidated EBITDA (as such terms were defined in the Prior Credit Agreement) financial covenants were deleted and a new Revenue Base (assuch term is defined in the Second Amended and Restated Credit Agreement) financial covenant was added; and (v) the key person event default provisionwas revised to refer specifically to Kevin Brandt and Ron Berlin. On April 1, 2019 the Company will issue warrants to purchase an aggregate of 1.2 million shares of Company common stock to the Investors, withan exercise price of $0.01 per share and an expiration date of April 1, 2029 (collectively, the “2019 Warrants”). The issuance of the 2019 Warrants occurredon April 1, 2019 and was a condition to the effectiveness of Second Amended and Restated Credit Agreement (See Note 16, “Subsequent Events” below). Long-term debt consists of the following (in thousands): December 31, 2018 December 31, 2017 Amounts due under the Credit Facility $55,787 $55,787 PIK interest payable related to the Credit Facility 27,178 11,582 Plus: 2% exit fee on Credit Facility 254 - 6% convertible senior unsecured notes due 2021 - 71,865 Gross long-term debt 83,219 139,234 Less: discount on Credit Facility (5,114) - Less: total debt issuance costs (166) (1,272)Long-term debt, less issuance costs $77,939 $137,962 All gross long-term debt will mature March 31, 2021 and become payable at that time. 78 (7)Stock-Based Compensation Xtant Medical Holdings, Inc. 2018 Equity Incentive Plan On August 1, 2018, our stockholders approved the Xtant Medical Holdings, Inc. 2018 Equity Incentive Plan (the “2018 Plan”) at the 2018 annualmeeting of stockholders of Xtant. The 2018 Plan became effective immediately upon approval by our stockholders and will expire on July 31, 2028, unlessterminated earlier. The 2018 Plan replaced the Amended and Restated Xtant Medical Equity Incentive Plan (the “Prior Plan”) with respect to future grants ofequity awards. The Prior Plan will continue to govern equity awards granted under the Prior Plan. The 2018 Plan permits the Board, or a committee thereof, togrant to eligible employees, non-employee directors and consultants of the Company non-statutory and incentive stock options, stock appreciation rights,restricted stock awards, restricted stock units, deferred stock units, performance awards, non-employee director awards, and other stock-based awards. TheBoard may select 2018 Plan participants and determine the nature and amount of awards to be granted. Subject to adjustment as provided in the 2018 Plan,the number of shares of our common stock available for issuance under the 2018 Plan is 1,307,747 shares. Under the 2018 Plan, shares of our common stockrelated to awards granted under the plan that terminate by expiration, forfeiture, cancellation or otherwise without the issuance of the shares will be availableagain for grant under the plan. After the approval and effectiveness of the 2018 Plan, the Board granted various awards thereunder to certain officers and employees, consisting ofstock option grants to purchase an aggregate of 650,770 shares of our common stock and restricted stock units covering 40,000 shares. In addition, arestricted stock award for 26,042 shares was granted to one of our non-employee directors. As of December 31, 2018, of the 1,307,747 shares of common stock available for issuance under the 2018 Plan, 716,812 shares were subject tooutstanding awards under the 2018 Plan and 590,935 shares remained available for future issuance. Shares of common stock issued under the 2018 Plan maybe newly issued shares or reacquired shares. From time to time, we have granted options to purchase shares of our common stock outside of any stockholder-approved plan to new hires (collectively the “Non-Plan Grants”). Stock options granted under the 2018 Plan may be either incentive stock options to employees, as defined in Section 422A of the Internal RevenueCode of 1986, or non-qualified stock options. The exercise price of all stock options granted under the 2018 Plan must be at least equal to the fair marketvalue of the shares of common stock on the date of the grant. The 2018 Plan is administered by the Board. Stock options granted under the 2018 Plan aregenerally not transferable, vest in installments over the requisite service period and are exercisable during the stated contractual term of the option only bysuch optionee. Stock-based compensation expense recognized in the consolidated statements of operations for the year ended December 31, 2018 and 2017 isbased on awards expected to vest and reflects an estimate of awards that will be forfeited. ASC 718 requires forfeitures to be estimated at the time of grant andrevised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock options to purchase an aggregate of 650,770 shares ofcommon stock were issued during the year ended December 31, 2018; zero options were issued during the year ended December 31, 2017. 79 Stock option activity, including options granted under the 2018 Plan, the Prior Plan and the Non-Plan Grants, was as follows (in thousands, exceptnumber of shares and per share amounts): 2018 2017 Weighted Weighted Weighted AverageFair Weighted AverageFair AverageExercise Value atGrant AverageExercise Value atGrant Shares Price Date Shares Price Date Outstanding at January 1 67,465 $71.03 $36.85 100,492 $62.52 $33.84 Granted 650,770 4.79 4.15 - - - Cancelled or expired (221,277) 13.45 7.77 (33,027) 45.13 30.74 Outstanding at December 31 496,958 $9.90 $6.62 67,465 $71.03 $36.85 Exercisable at December 31 66,188 $46.88 $25.92 32,750 $128.39 $62.23 The estimated fair value of stock options granted is done using the Black-Scholes-Merton method applied to individual grants. Key assumptionsused to estimate the fair value of stock awards are as follows: Year Ended December 31, 2018 2017 Risk free interest rate 2.97% -Dividend Yield 0% -Expected term 10.0 years - Expected Volatility 89% -Expected forfeiture rate 20% - The aggregate intrinsic value of options outstanding as of December 31, 2018 was zero because the closing price of the stock at December 31, 2018was less than the exercise prices of all options issued under the Prior Plan or the 2018 Plan were fully vested and expensed due to the change of control as aresult of the Corporate Restructuring, noted above. Total stock-based compensation expense recognized for employees and directors was $0.7 million and $0.2 million for the years ended December 31,2018 and 2017, respectively, and was recognized as Non-cash compensation expense as discussed below. During the year ended December 31, 2018, the Board granted an aggregate of 93,750 shares of restricted stock to our non-employee directors of theCompany. These awards will vest and become non-forfeitable with respect to one-half of the underlying shares on February 14, 2019 and the remaining halfon February 14, 2020. The total grant date fair value of these restricted stock awards amounts to $0.4 million in the aggregate or $4.80 per share and is beingrecognized ratably over the vesting period. During the year ended December 31, 2018, $0.2 million was expensed as compensation. On August 15, 2018, the Company issued restricted stock units covering 40,000 shares, with a value of $6.20 per share, to an employee and during theyear ended December 31, 2018 recognized $16 thousand of expense associated with this award. 80 On July 25, 2017, we granted 25,974 shares of restricted stock to certain former non-employee directors of the Company. These awards became fullyvested and non-forfeitable on February 13, 2018 as a result of the Restructuring, which constituted a change of control under the Prior Plan. The total expenseof these restricted stock awards, which amounted to $0.2 million in the aggregate, or $9.24 per share, was being recognized over the vesting period as Non-cash compensation expense. During the three months ended March 31, 2018, the remaining $0.1 million of expense was recognized as non-cashcompensation expense. Effective October 6, 2016, the Board granted our former Chief Executive Officer, an option to purchase 25,000 shares of common stock at an exerciseprice of $13.32 per share. This option was granted outside the Prior Plan as an inducement option. As a result of the Restructuring, which constituted achange of control under the option agreement, this option became fully vested on February 13, 2018 and was fully expensed during the three months endedMarch 31, 2018. On August 15, 2018, the Board granted our former Chief Executive Officer an additional option to purchase 200,000 shares of commonstock at an exercise price of $6.20 per share, which was scheduled to vest and become exercisable in four equal annual installments, commencing on August15, 2019. The option to purchase 200,000 shares of common stock terminated as a result of the termination of his employment and his vested options topurchase 25,000 shares of common stock expired January 10, 2019, which is the 90th day after his termination date. As of December 31, 2018, 590,935 shares are available under the 2018 Plan, prior to forfeited shares being made available for reissuance. 81 (8)Warrants 2018 Warrants The Company issued warrants to purchase an aggregate of 1.2 million shares of Company common stock to the Investors, with an exercise price of$0.01 per share and an expiration date of August 1, 2028. The issuance of the 2018 Warrants occurred on September 17, 2018 and was a condition to theeffectiveness of the 25th Amendment. The fair value of these warrants upon issue was determined to be $5.1 million (see Note 6). In accordanc e with ASC815-40, the 2018 Warrants meet all requirements to be classified as equity awards. The number of shares of Company common stock issuable upon exerciseof the 2018 Warrants are subject to standard and customary anti-dilution provisions for stock splits, stock dividends or similar transactions. The following table summarizes our warrant activities for the period ended December 31, 2018: Weighted Common Average Stock Exercise Warrants Price Outstanding as of January 1, 2017 524,277 $26.76 Expired (4,360) 135.36 Outstanding at January 1, 2018 519,917 $25.68 Issued 1,200,000 0.01 Expired (9,308) 88.84 Outstanding at December 31, 2018 1,710,609 $7.33 The estimated fair value was derived using the lattice model with the following weighted-average assumptions: Year Ended December 31, 2018 2017 Value of underlying common stock (per share) $1.61 $6.84 Risk free interest rate 2.48% 2.12%Expected term 3.6 years 4.6 years Volatility 92% 92%Dividend yield 0% 0% The following table summarizes our activities related to warrants accounted for as a derivative liability for the years ended December 31, 2018 and2017: 2018 2017 Balance at January 1 93,759 93,759 Derivative warrants issued - - Derivative warrants exercised - - Derivative warrants expired (6,250) - Balance at December 31 87,509 93,759 We utilize a lattice model to determine the fair market value of the warrants accounted for as liabilities. The valuation model accommodates theprobability of exercise price adjustment features as outlined in the warrant agreements. We recorded an unrealized gain of $0.1 million resulting from thechange in the fair value of the warrant derivative liability for the year ended 2018. Under the terms of some of our warrant agreements, at any time while thewarrant is outstanding, the exercise price per share can be reduced to the price per share of future subsequent equity sales of our common stock or a commonstock equivalent that is lower than the exercise price per share as stated in the warrant agreement. 2019 Warrants On April 1, 2019, the Company will issue warrants to purchase an aggregate of 1.2 million shares of Company common stock to the Investors, withan exercise price of $0.01 per share and an expiration date of April 1, 2029. The issuance of the 2019 Warrants was a condition to the effectiveness of theSecond Amended and Restated Credit Agreement, as described below under Note 16, “Subsequent Events” below. The 2019 Warrants are expected to meetall the requirements to be classified as equity awards in accordance with ASC 815-40. However, our final analysis will be completed in connection with thefiling of our March 31, 2019 interim financial statements on Form 10-Q. The number of shares of Company common stock issuable upon exercise of the 2019Warrants are subject to standard and customary anti-dilution provisions for stock splits, stock dividends or similar transactions. Total outstanding common stock warrants as of April 1, 2019 were 2,910,609, with a weighted average exercise price of $4.31. 82 (9)Commitments and Contingencies Operating Leases We currently lease six office facilities, having terminated the Miamisburg, OH lease on February 28, 2019. These leases are under non-cancelableoperating lease agreements with expiration dates between 2019 and 2025. We have the option to extend certain leases to five or ten-year term(s) and we havethe right of first refusal on any sale. Future minimum payments, (including payments related to the February 1, 2019 renewal for 732 Cruiser Lane premises) for the next five years andthereafter as of December 31, 2018, under these operating leases, are as follows (in thousands): 2019 $817 2020 528 2021 507 2022 485 2023 426 Thereafter 662 Total $3,425 Rent expense was $0.8 million for the years ended December 31, 2018 and 2017, respectively. Rent expense is determined using the straight-linemethod of the minimum expected rent paid over the term of the agreement. We have no contingent rent agreements. Capital Leases Future minimum payments for the next five years and thereafter as of December 31, 2018, under these capital leases, are as follows (in thousands): 2019 $502 2020 217 2021 - 2022 - 2023 - Thereafter - Total minimum lease payments 719 Less amount representing interest (89)Present value of obligations under capital leases 630 Less current portion (426)Long-term capital lease obligations $204 83 Litigation On August 10, 2017, a civil suit complaint was filed against Xtant in the United States District Court, District of Nevada by Axis Spine NV, LLC(“Axis”), Case No. 2:17-CV-02147-APG-VCF. The complaint alleges breach of contract, breach of the implied covenant of good faith and fair dealing, andtortious interference with prospective economic advantage with respect to an alleged medical device distribution relationship between the parties.Specifically, Axis alleges that Xtant owes payments to Axis for its medical device distributions. Axis seeks relief in the form of damages in an amount inexcess of $1.0 million. On March 6, 2019, the Court granted Xtant’s motion for summary judgment on Axis’s claims for breach of contract, and breach of thecovenant of good faith and fair dealing, but denied Xtant’s motion for summary judgment on Axis’s unjust enrichment claim. Xtant is evaluating itsalternatives in light of the court order. Because this matter is in early stages and because of the complexity of the case, we cannot estimate the possible loss orrange of loss, if any, associated with its resolution. However, there can be no assurance that the ultimate resolution of this matter will not result in a materialadverse effect on our business, financial condition or results of operations. On December 13, 2018, a complaint was filed by RSB Spine, LLC against Xtant Medical Holdings, Inc. which claims that some of our products,including the Irix-ATM Lumbar Integrated Fusion System and the Irix-CTM Cervical Integrated Fusion System, infringe certain of RSB Spine’s patents. Thecomplaint seeks an adjudication of infringement, an injunction against future infringement, unspecified damages for infringement, a finding that suchinfringement is willful, and treble damages for such willful infringement. This action was brought in the United States District Court for the District ofDelaware. We intend to vigorously defend the claims in this action. Because this matter is in early stages and because of the complexity of the case, wecannot estimate the possible loss or range of loss, if any, associated with its resolution. However, there can be no assurance that the ultimate resolution of thismatter will not result in a material adverse effect on our business, financial condition or results of operations. In October 2016, Phoenix Surgical, Inc., a former distributor sued Xtant for its alleged participation in a scheme orchestrated by a former PhoenixSurgical sales representative to divert sales away from Phoenix Surgical to another entity. The other entity diverted approximately $285,000 in sales (orapproximately $205,000 in gross profit) that would otherwise have gone to Phoenix Surgical. Phoenix Surgical alleges that Xtant and one of its formeremployees participated in this diversion of sales and that Xtant is liable to Phoenix Surgical for its loss, with treble damages for violation of a Connecticutstatute. Xtant claims that the other entity was a legitimate distributor, its former employee acted on his own and Xtant had no way of knowing the otherparties were diverting sales. Phoenix initially sued Xtant in Connecticut and in federal bankruptcy court because some other individuals involved have filedbankruptcy. Xtant was dismissed from those actions, and the dispute is now subject to arbitration in Colorado. The arbitration is scheduled for July 2019. In addition, we are engaged in ordinary routine litigation incidental to our business from time to time, including product liability dispute. Indemnifications Our arrangements generally include limited warranties and certain provisions for indemnifying customers against liabilities if our products orservices infringe a third-party’s intellectual property rights. To date, we have not incurred any material costs as a result of such warranties or indemnificationprovisions and have not accrued any liabilities related to such obligations in the accompanying financial statements. We have also agreed to indemnify our directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlementamounts incurred by any of these persons in any action or proceeding to which any of those persons is, or is threatened to be, made a party by reason of theperson’s service as a director or officer, including any action by us, arising out of that person’s services as our director or officer or that person’s servicesprovided to any other company or enterprise at our request. (10)Income Taxes The Company’s provision for income taxes differs from applying the statutory U.S. Federal income tax rate to income before taxes. The primarydifference results from providing for state income taxes and from deducting certain expenses for financial statement purposes but not for federal income taxpurposes. The components of income loss before provision for income taxes consist of the following (in thousands): Year Ended December 31, 2018 2017 United States $(70,059) $(52,411) Total $(70,059) $(52,411) The components of the income tax provision are as follows (in thousands): Year Ended December 31, 2018 2017 Current: Federal $ - $ - State - - Total current - - Deferred: Federal - - State - - Total deferred - - Total Provision for Income Taxes $- $- 84 The reconciliation of income tax attributable to operations computed at the U.S. Federal statutory income tax rate of 21% to income tax expense isas follows (in thousands): Year Ended December 31, 2018 2017 Statutory Federal tax rate $(14,712) $(18,315)Valuation allowance 7,270 6,390 State income taxes, net of Federal benefit (1,740) (2,818)Goodwill impairment 8,049 - Change in state income tax rate 396 755 Change in warrant derivative liability (25) (71)Stock compensation adjustment and other reconciling items 349 (190)Tax Cuts and Jobs Act - 11,772 Nondeductible interest 247 1,473 Restructuring expenses 117 952 Other - - Nondeductible meals and entertainment expense 49 52 Total Provision for Income Taxes $- $- Deferred tax components are as follows (in thousands): At December 31, 2018 2017 Deferred tax assets: Accrued liability for vacation $77 $81 Accrued commissions and bonuses / compensation 332 60 Accrued contingencies 121 68 Amortization 40 - Bad debt reserve 552 580 Charitable contributions carryforward 7 8 Interest expense 2,173 - Inventory reserve 3,200 2,075 Net operating loss carryovers 22,996 23,174 Stock option compensation 475 560 Other 24 42 Total deferred tax assets 29,997 26,648 Deferred tax liabilities: Depreciation (137) (704)Amortization - (3,355)Total deferred tax liabilities (137) (4,059) Valuation allowance (29,860) (22,589) Net deferred tax assets $- $- The ultimate realization of deferred tax assets is dependent upon the existence, or generation, of taxable income in the periods when those temporarydifferences and net operating loss carryovers are deductible. Management considers the scheduled reversal of deferred tax liabilities, taxes paid in carryoveryears, projected future taxable income, available tax planning strategies, and other factors in making this assessment. Based on available evidence,management does not believe it is more likely than not that all of the deferred tax assets will be realized. Accordingly, the Company has established avaluation allowance equal to the net realizable deferred tax assets. The valuation allowance increased by $7.3 million in 2018 and increased by $6.4 millionin 2017. 85 At December 31, 2018 and 2017, the Company had total domestic Federal and state net operating loss carryovers of approximately $158.7 millionand $164.8 million, respectively. Federal and state net operating loss carryovers both expire at various dates between 2024 and 2038. Federal net operatinglosses generated in 2018 have an indefinite carryforward and are only available to offset 80% taxable income. Under the Tax Reform Act of 1986, as amended, the amounts of and benefits from net operating loss carryovers and research and developmentcredits may be impaired or limited in certain circumstances. Events which cause limitations in the amount of net operating losses that the Company mayutilize in any one year include, but are not limited to, a cumulative ownership change of more than 50%, as defined, over a three-year period. The Companyhas not performed an analysis to determine if an ownership change has occurred for 2018 or 2017. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. Prior GAAP required an entity torecognize excess tax benefit or deficiency as additional paid-in capital. To simplify the presentation of stock compensation, the amendments in this Updaterequire that the excess tax benefit or deficiency is recognized as expense. For non-public business entities, the amendments in this Update are effective forfinancial statements issued for annual periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15,2018. The Company adopted the update as of January 1, 2017. Due to a full valuation allowance, there was no qualitative impact to the tax provision uponadoption. On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”), was signed into legislation. As a result of the lower enacted corporate tax rate, theCompany has remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally21%. The amount recorded at December 31, 2017 related to the remeasurement of the Company’s deferred tax balance was $11.8 million, that was fully offsetby a corresponding decrease to the valuation allowance. On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”), was issued to address the application of U.S. GAAP in situations when aregistrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accountingfor certain income tax effects of the Act. In accordance with SAB 118, the Company has provisionally determined that there is no tax deferred tax benefit orexpense with respect to the remeasurement of certain deferred tax assets and liabilities due to the full valuation allowance against net deferred tax assets. TheCompany analyzed certain aspects of the Act further and refined its calculations during 2018. The Company has completed their analysis of the impact of theTax Act at December 31, 2018 and has incorporated it into the current year provision. The most significant impact as a result of the Act, beginning in tax year2018, is the limitation placed on the deductibility of interest expense. The 2015 through 2017 tax years remain open to examination by the Internal Revenue Service and various other state tax agencies. These taxingauthorities have the authority to examine those tax years until the applicable statute of limitations expire. The Company did not recognize any material interest or penalties related to income taxes for the years ended December 31, 2018 and 2017. (11)Equity Convertible Note Indenture During the first quarter of 2018, in connection with our Restructuring (defined above), all of the outstanding 6.00% convertible senior unsecured notesdue 2021 were converted or exchanged into shares of our common stock and the Indenture governing such notes was discharged. On January 17, 2018, theInvestors converted $1.6 million aggregate principal amount of 6.00% convertible senior unsecured promissory notes due in 2021, which were issuedeffective January 17, 2017, plus accrued and unpaid interest, into 189,645 shares of our common stock. On February 14, 2018, an additional $70.3 millionaggregate principal amount of notes, plus accrued and unpaid interest, were exchanged for 10,401,309 newly-issued shares of our common stock. 86 Private Placement SPA On February 14, 2018, we sold to the Investors pursuant to the Private Placement SPA 945,819 shares of our common stock, at a price of $7.20 pershare, for aggregate proceeds of $6.8 million. Registration Rights Agreement On May 15, 2018, we filed a shelf resale registration statement with the SEC pursuant to our obligations under the Registration Rights Agreement.This registration statement was declared effective by the SEC on June 4, 2018. Rights Offering On May 18, 2018, we distributed to holders of our common stock, at no charge, non-transferable subscription rights to purchase up to an aggregate of1,137,515 shares of our common stock (the “Rights Offering”). In the Rights Offering, holders received 0.0869816 subscription rights for each share ofcommon stock held on the record date, April 27, 2018. The units were priced at $7.20 per unit. The Rights Offering expired on June 18, 2018, at which timethe rights were no longer exercisable. We issued 129 shares of our common stock in the Rights Offering, resulting in $0.9 thousand in gross proceeds to us. (12)Employee Benefit Plans The Company combined the previous two 401(k) plans for Bacterin and X-spine in 2017. Under the combined plan, the employee becomes qualifiedupon starting employment. In 2018, the Company contributed $0.3 million as part of the employer match program. Terms for the plan are as follows: Discretionary Match: 3% Contribution Limit: $18,000 or the statutorily prescribed limit (13)Supplemental Disclosure of Cash Flow Information Supplemental cash flow information is as follows (in thousands): Year Ended December 31, 2018 2017 Cash paid during the period for: Interest $186 $627 Non-cash activities: Issuance of capital leases $84 $173 Interest converted into common stock $556 $480 Conversion of convertible debt to equity $71,865 $- Convertible PIK interest $4,764 $- Conversion of interest related to the Credit Facility to long-term debt $7,977 $- Write-off of convertible debt issuance cost $1,012 $- Debt discount on long-term credit facility $5,114 $- Net Transfer of inventory to property and equipment $149 $- RSU vesting $120 $- 87 (14) Related Party Transactions The Investors, which collectively own approximately 70% of our outstanding common stock, are the sole holders of our outstanding long-term debt.In addition, as described in more detail under Note (1), we are parties to an Investor Rights Agreement and Registration Rights Agreement with the Investors.Transactions between the Company and the Investors are conducted under the provisions of Amended and Restated Credit Agreement, the Investor RightsAgreement and the Registration Rights Agreement, as noted above. (15)Segment and Geographic Information The Company’s management reviews financial results and manages the business on an aggregate basis. Therefore, financial results are reported in asingle operating segment: the development, manufacture and marketing of orthopedic medical products and devices. The Company attributes revenues to geographic areas based on the location of the customer. Approximately 95% and 97% of revenue were in theUnited States, respectively, for the years ended December 31, 2018 and 2017. Total revenue by major geographic area is as follows (in thousands): Year EndedDecember 31, 2018 2017 United States $68,880 $79,738 Rest of World 3,323 2,874 Total $72,203 $82,612 (16)Subsequent Events On March 29, 2019, Xtant Medical Holdings, Inc., and our subsidiaries, Bacterin International, Inc., Xtant Medical Systems, Inc. and X-spineSystems, Inc., entered into a Second Amended and Restated Credit Agreement (“Second Amended and Restated Credit Agreement”) with OrbiMed RoyaltyOpportunities II, LP and ROS Acquisition Offshore LP. (collectively, the “Investors”), which amended and restated the prior Amended and Restated CreditAgreement dated as of July 27, 2015 among the parties thereto, and as subsequently amended through the Twenty-Fifth Amendment to the Amended andRestated Credit Agreement, the “Prior Credit Agreement”). Under the terms of the Second Amended and Restated Credit Agreement, the Prior Credit Agreement was amended to provide that: ●X-Spine Systems, Inc. may request additional term loans from the Investors in the remaining amount available to be requested as AdditionalDelayed Draw Loans, which was approximately $2,200,000 as of the date of the Second Amended and Restated Credit Agreement, and mayrequest new additional term loans in an aggregate amount of up to $10,000,000, the making of each such Loan to be subject to thediscretion of the Investors and the Company’s production of a thirteen-week cash flow forecast that is approved by the Investors and showsa projected cash balance for the following two-week period of less than $1,500,000, as well as the satisfaction (or waiver in writing by eachInvestor) of conditions precedent, including closing certificate, delivery of budget, and other satisfactory documents;●No interest will accrue on the Loans under the Second Amended and Restated Credit Agreement from and after January 1, 2019 until March31, 2020;●Beginning April 1, 2020 through the maturity date of the Second Amended and Restated Credit Agreement, interest payable in cash willaccrue on the Loans under the Credit Agreement at a rate per annum equal to the sum of (i) 10.00% plus (ii) the higher of (x) the LIBO Rate(as such term is defined in the Second Amended and Restated Credit Agreement) and (y) 2.3125%;●The maturity date of the Loans is March 31, 2021;●The Consolidated Senior Leverage Ratio and Consolidated EBITDA (as such terms were defined in the Prior Credit Agreement) financialcovenants were deleted and a new Revenue Base (as such term is defined in the Second Amended and Restated Credit Agreement) financialcovenant was added; and●The key person event default provision was revised to refer specifically to Kevin Brandt and Ron Berlin. On April 1, 2019 Xtant will issue warrants to purchase an aggregate of 1.2 million shares of Company common stock to the Investors, with anexercise price of $0.01 per share and an expiration date of April 1, 2029. The issuance of the 2019 Warrants occurred on April 1, 2019 and was a condition tothe effectiveness of the Second Amended and Restated Credit Agreement. The 2019 Warrants are expected to meet all the requirements to be classified asequity awards in accordance with ASC 815-40. However, our final analysis will be completed in connection with the filing of our March 31, 2019 interimfinancial statements on Form 10-Q. The number of shares of Company common stock issuable upon exercise of the 2019 Warrants are subject to standard andcustomary anti-dilution provisions for stock splits, stock dividends or similar transactions. The issuance of the 2019 Warrants was exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”),pursuant to Section 4(a)(2) thereof and/or Regulation D promulgated thereunder. The issuance of any shares of Company common stock in connection withthe exercise of the 2019 Warrants is also expected to be exempt from the registration requirements of the Securities Act, pursuant to Section 4(a)(2) thereofand/or Regulation D promulgated thereunder. The Investors, which collectively own approximately 70% of the Company’s outstanding common stock, and beneficially own, with their warrants,approximately 75% of the Company’s outstanding common stock, are the sole holders of the Company’s outstanding long-term debt. In addition, asdescribed in more detail in the definitive proxy statement for the Company’s 2018 annual meeting of stockholders filed with the SEC on June 26, 2018, asamended, the Company is a party to an Investor Rights Agreement and Registration Rights Agreement with the Investors in addition to the Second Amendedand Restated Credit Agreement. 88 Item 9.Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. Item 9A.Controls and Procedures Evaluation of Disclosure Controls and Procedures Our management with the participation of our chief executive officer and principal financial officer evaluated the effectiveness of our disclosurecontrols and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of December 31, 2018. Based upon that evaluation, our chief executiveofficer and principal financial officer concluded that as of December 31, 2018, our disclosure controls and procedures were effective. Management’s Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in rule 13a-15(f) under the Securities Exchange Act of 1934 as amended. Under the supervision and with the participation of senior and executive management, weconducted an evaluation of our internal controls over financial reporting based upon the framework Internal Control - Integrated Framework (2013) asoutlined by COSO, the Committee of Sponsoring Organizations of the Treadway Commission. Our internal control over financial reporting is a processdesigned to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes inaccordance with accounting principles generally accepted in the United States of America. Because of its inherent limitations, internal control over financialreporting may not prevent or detect misstatements. Also, projections of an evaluation of effectiveness to future periods are subject to the risk that controlsmay become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Based on our evaluation under the framework Internal Control - Integrated Framework (2013), management concluded that our internal control overfinancial reporting was effective as of December 31, 2018.

[Reserved] (c) Special Distributions; Above Market Purchases of Securities. (i) If the Company shall issue or distribute to any holder or holders of Shares evidences of indebtedness, any other securities of theCompany or any cash, property or other assets (excluding (i) a Share Reorganization and (ii) a Share Distribution), whether or not accompanied by a purchase,redemption or other acquisition of Shares (any such nonexcluded event being herein called a “Special Distribution”), then the Warrant Holder shall beentitled to a pro-rata Share of such Special Distribution as though the Warrant Holder had fully exercised this Warrant immediately prior to the record date forsuch Special Distribution, and the Company shall pay or distribute such pro-rata share to Warrant Holder when paid or distributed to the holders of theShares. A reclassification of the Shares (other than a change in par value, or from par value to no par value or from no par value to par value) into shares of anyother class of stock shall be deemed to be a distribution by the Company to the holders of its Shares of such class of stock and, if the outstanding Shares shallbe changed into a larger or smaller number of Shares as part of such reclassification, a Share Reorganization. (ii) If, at any time after the date hereof, the Company or any Subsidiary shall repurchase (a “Repurchase”), by self-tender offer or otherwise,any securities of the Company at an aggregate repurchase price that exceeds the aggregate Market Price for the securities repurchased determined as of theBusiness Day immediately prior to the earliest of (i) the date of such Repurchase, (ii) the commencement of an offer to repurchase or (iii) the publicannouncement of either (such date being referred to as the “Determination Date”), then the Exercise Price and the number of Warrant Shares issuable uponexercise of this Warrant shall be adjusted as follows: The Exercise Price shall be reduced to an amount equal to the product of (A) the Exercise Price in effect immediately prior to such issuanceor sale times (B) a fraction, (I) the numerator of which shall be (x) the product of (1) the Market Price for the Shares as of the DeterminationDate times (2) the number of Shares outstanding immediately following the consummation of the Repurchase less (y) the RepurchasePremium (as defined below), and (II) the denominator of which shall be (x) the product of (1) the Market Price for the Shares as of theDetermination Date times (2) the number of Shares outstanding immediately following the consummation of the Repurchase. The number of Warrant Shares issuable upon exercise of this Warrant shall be increased to the number of Shares determined by multiplying(x) the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such distribution times (y) a fraction (1) thenumerator of which shall be the Exercise Price in effect immediately prior to the adjustment in clause (A) of this Section 4(c)(ii) and (2) thedenominator of which shall be the Exercise Price in effect immediately after such adjustment. 6 The amount by which the aggregate repurchase price for all securities repurchased in any Repurchase (including for such purposes any fees or otherdirect or indirect consideration payable in connection therewith) exceeds the aggregate Market Price for such securities is referred to as the “RepurchasePremium.” (d) Capital Reorganization. Without limiting any of the other provisions hereof, if any (i) capital reorganization; (ii) reclassification of the capitalstock of the Company; (iii) merger, consolidation or reorganization or other similar transaction or series of related transactions which results in the votingsecurities of the Company outstanding immediately prior thereto representing immediately thereafter (either by remaining outstanding or by being convertedinto voting securities of the surviving or acquiring entity) less than 50% of the combined voting power of the voting securities of or economic interests in theCompany or such surviving or acquiring entity outstanding immediately after such merger, consolidation or reorganization; (iv) sale, lease, license, transfer,conveyance or other disposition of all or substantially all of the assets of the Company; (v) sale of shares of capital stock of the Company, in a singletransaction or series of related transactions, representing at least 50% of the voting power of the voting securities of or economic interests in the Company; or(vi) the acquisition by any “person” (together with his, her or its Affiliates) or “group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act)acquires, directly or indirectly, the beneficial ownership (as such term is defined in Rule 13d-3 promulgated under the Exchange Act) of outstanding shares ofcapital stock and/or other equity securities of the Company, in a single transaction or series of related transactions (including, without limitation, one or moretender offers or exchange offers), representing at least 50% of the voting power of or economic interests in the then outstanding shares of capital stock of thecorporation (each of (i)-(vi) above a “Corporate Reorganization”) shall be effected, then the Company shall use its best efforts to ensure that lawful andadequate provision shall be made whereby each Warrant Holder shall thereafter continue to have the right to purchase and receive upon the basis and uponthe terms and conditions herein specified and in lieu of the Warrant Shares issuable upon exercise of the Warrants held by such Warrant Holder, shares ofstock in the surviving or acquiring entity (“Acquirer”), as the case may be, such that the aggregate value of the Warrant Holder’s warrants to purchase suchnumber of shares, where the value of each new warrant to purchase one share in the Acquirer is determined in accordance with the Black-Scholes OptionPricing formula set forth in Appendix (A) hereto, is equivalent to the aggregate value of the Warrants held by such Warrant Holder, where the value of eachWarrant to purchase one share in the Company is determined in accordance with the Black-Scholes Option Pricing formula set forth Appendix (B) hereto.Furthermore, the new warrants to purchase shares in the Acquirer referred to herein shall have the same expiration date as the Warrants, and shall have a strikeprice, KAcq, that is calculated in accordance with Appendix (A) hereto. For the avoidance of doubt, if the surviving or acquiring entity, as the case may be, isa member of a consolidated group for financial reporting purposes, the “Acquirer” shall be deemed to be the parent of such consolidated group for purposesof this Section 4(d) and Appendix (A) hereto. 7 Moreover, appropriate provision shall be made with respect to the rights and interests of each Warrant Holder to the end that the provisions hereof(including, without limitation, provision for adjustment of the Warrant Price) shall thereafter be applicable, as nearly equivalent as may be practicable inrelation to any shares of stock thereafter deliverable upon the exercise thereof. The Company shall not effect any such Corporate Reorganization unless priorto or simultaneously with the consummation thereof the successor corporation resulting from such consolidation or merger, or the corporation purchasing orotherwise acquiring such assets or other appropriate corporation or entity shall assume by written instrument, reasonably deemed by the Board of Directors ofthe Company and the Requisite Holders to be satisfactory in form and substance, the obligation to deliver to the holder of the Warrants, at the last address ofsuch holder appearing on the books of the Company, such shares of stock, as, in accordance with the foregoing provisions, such holder may be entitled topurchase, and the other obligations under these Warrants. The provisions of this Section 4(d) shall similarly apply to successive Corporate Reorganizations. Ifthe Company, in spite of using its best efforts, is unable to cause these Warrants to continue in full force and effect until the Expiration Date in connectionwith any Corporate Reorganization, then the Company shall pay the Warrant Holders an amount per Warrant to purchase one share in the Company that iscalculated in accordance with the Black-Scholes Option Pricing formula set forth in Appendix (B) hereto. Such payment shall be made in cash in the eventthat the Corporate Reorganization results in the Company or the shareholders of the Company receiving cash from the Acquirer at the closing of thetransaction, and shall be made in shares of the Company (with the value of each share in the Company is determined according to SCorp in Appendix (B)hereto) for all other Corporate Reorganizations. In the event that a Corporate Reorganization involves the payment of cash as well as other securities, suchpayment to the Warrant Holders shall be also be made in both cash and shares in the same proportion as the cash and non-cash portions of the considerations. (e) Adjustment Rules. (i) Any adjustments pursuant to this Section 4 shall be made successively whenever any event referred to herein shall occur, except that,notwithstanding any other provision of this Section 4, no adjustment shall be made to the number of Warrant Shares to be delivered to the Warrant Holder (orto the Exercise Price) if such adjustment represents less than 1% of the number of Warrant Shares previously required to be so delivered, but any lesseradjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which together with any adjustments socarried forward shall amount to 1% or more of the number of Warrant Shares to be so delivered. (ii) No adjustments shall be made pursuant to this Section 4 in respect of the issuance of Warrant Shares upon exercise of the Warrant; (iii) If the Company shall take a record of the holders of its Shares for any purpose referred to in this Section 4, then (x) such record dateshall be deemed to be the date of the issuance, sale, distribution or grant in question and (y) if the Company shall legally abandon such action prior toeffecting such action, no adjustment shall be made pursuant to this Section 4 in respect of such action. (iv) In computing adjustments under this Section 4, (A) fractional interests in Shares shall be taken into account to the nearest one-thousandth of a Share, and (B) calculations of the Exercise Price shall be carried to the nearest one-thousandth of one cent. (f) Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustmentpursuant to this Section 4, the Company shall take any action which may be necessary, including obtaining regulatory approvals or exemptions, in order thatthe Company may thereafter validly and legally issue as fully paid and nonassessable all Shares which the Warrant Holder is entitled to receive upon exerciseof the Warrant. 8 (g) Notice of Adjustment. Not less than 20 days prior to the record date or effective date, as the case may be, of any action which requires or mightrequire an adjustment or readjustment pursuant to this Section 4, the Company shall give notice to the Warrant Holder of such event, describing such event inreasonable detail and specifying the record date or effective date, as the case may be, and, if determinable, the required adjustment and computation thereof.If the required adjustment is not determinable as the time of such notice, the Company shall give notice to the Warrant Holder of such adjustment andcomputation as soon as reasonably practicable after such adjustment becomes determinable.

The Company will also keep copies of all suchreports at its office and will cause the same to be available for inspection at such office during normal business hours by the Warrant Holder or anyprospective purchaser of this Warrant designated by the Warrant Holder. (h) Subsequent Warrants. Irrespective of any adjustments in the Exercise Price or the number of Warrant Shares issuable upon exercise of thisWarrant, any successor or replacement warrants issued theretofore or thereafter may continue to express the same Exercise Price per Share and number andkind of Warrant Shares as are stated in this Warrant. (i) Disputes. Any dispute which arises between the Warrant Holder and the Company with respect to the calculation of the adjusted Exercise Price orWarrant Shares issuable upon exercise shall be determined by the independent auditors of the Company, and such determination shall be binding upon theCompany and the holders of the Warrants and the Warrant Shares if made in good faith and without manifest error. (j) Other Actions Affecting Shares. (i) Equitable Equivalent.

Upon receipt of such opinion, the Company will promptly mail a copy thereof to the holder of this Warrant and shall makethe adjustments described therein. 9 (ii) No Avoidance. The Company shall not, by amendment of its certificate of incorporation or by-laws or through any consolidation,merger, reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance orperformance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all suchaction as may be necessary or appropriate in order to protect the rights of the holder of this Warrant against unlimited dilution or other impairment as if theholder was a shareholder of the Company entitled to the benefit of fiduciary duties afforded to shareholders under Delaware law. (k) Calculation of Consideration Received. The consideration for the issue or sale of any Share Distribution shall, irrespective of the accountingtreatment of such consideration: (i) insofar as it consists of cash, be computed at the amount of cash actually received by the Company without reduction for any expensespaid or incurred by the Company or any commissions or compensations paid or concessions or discounts allowed to underwriters, dealers or othersperforming similar services in connection with such issue or sale; (ii) insofar as it consists of property (including securities) other than cash actually received by the Company, be computed at the AppraisedValue thereof at the time of such issue or sale; and (iii) insofar as it consists neither of cash nor of other property, be computed as having no value. (l) Adjustment of Par Value. If for any reason (including the operation of the adjustment provisions set forth in this Warrant), the Exercise Price onany date of exercise of this Warrant shall not be lawful and adequate consideration for the issuance of the relevant Warrant Shares, then the Company shalltake such steps as are necessary (including the amendment of its certificate of incorporation so as to reduce the par value of the Shares) to cause such ExercisePrice to be adequate and lawful consideration on the date the payment thereof is due, but if the Company shall fail to take such steps, then the Companyacknowledges that the Warrant Holder shall have been damaged by the Company in an amount equal to an amount, which, when added to the total ExercisePrice for the relevant Warrant Shares, would equal lawful and adequate consideration for the issuance of such Warrant Shares, and the Company irrevocablyagrees that if the Warrant Holder shall then forgive the right to recover such damages from the Company, such forgiveness shall constitute, and Companyshall accept such forgiveness as, additional lawful consideration for the issuance of the relevant Warrant Shares.

The Company acknowledges that the provisions of clause (ii) are intended, in part, to ensure that a full or partial exchangeof this Warrant pursuant to such clause (ii) will qualify as a conversion, within the meaning of paragraph (d)(3)(ii) of Rule 144 under the Securities Act.

Any certificate for Warrant Shares issued at any time in exchange or substitution for any certificate bearing such legend (unless at that time suchWarrant Shares are registered under the Securities Act) shall also bear such legend unless, in the written opinion of counsel selected by the holder of suchcertificate (who may be an employee of such holder), which counsel and opinion shall be reasonably acceptable to the Company, the Warrant Sharesrepresented thereby need no longer be subject to restrictions on resale under the Securities Act. If the Warrant is exercised when there is an effectiveregistration statement covering the underlying Warrant Shares, the certificate for the Warrant Shares shall not bear a legend. 4 (e) No Fractional Shares.

Section 4. Antidilution Provisions. The Exercise Price in effect at any time, and the number of Warrant Shares that may be purchased upon anyexercise of the Warrant, shall be subject to change or adjustment as follows: (a) Share Reorganization. If the Company shall subdivide its outstanding Shares into a greater number of Shares, by way of a stock split, stockdividend or otherwise, or consolidate its outstanding Shares into a smaller number of Shares (any such event being herein called a “Share Reorganization”),then (i) the Exercise Price shall be adjusted, effective immediately after the effective date of such Share Reorganization, to a price determined by multiplyingthe Exercise Price in effect immediately prior to such effective date by a fraction, the numerator of which shall be the number of Shares outstanding on sucheffective date before giving effect to such Share Reorganization and the denominator of which shall be the number of Shares outstanding after giving effectto such Share Reorganization, and (ii) the number of Shares subject to purchase upon exercise of this Warrant shall be adjusted, effective at such time, to anumber determined by multiplying the number of Shares subject to purchase immediately before such Share Reorganization by a fraction, the numerator ofwhich shall be the number of Shares outstanding after giving effect to such Share Reorganization and the denominator of which shall be the number of Sharesoutstanding immediately before giving effect to such Share Reorganization. 5 (b) Share Distribution. [Reserved] (c) Special Distributions; Above Market Purchases of Securities. (i) If the Company shall issue or distribute to any holder or holders of Shares evidences of indebtedness, any other securities of theCompany or any cash, property or other assets (excluding (i) a Share Reorganization and (ii) a Share Distribution), whether or not accompanied by a purchase,redemption or other acquisition of Shares (any such nonexcluded event being herein called a “Special Distribution”), then the Warrant Holder shall beentitled to a pro-rata Share of such Special Distribution as though the Warrant Holder had fully exercised this Warrant immediately prior to the record date forsuch Special Distribution, and the Company shall pay or distribute such pro-rata share to Warrant Holder when paid or distributed to the holders of theShares. A reclassification of the Shares (other than a change in par value, or from par value to no par value or from no par value to par value) into shares of anyother class of stock shall be deemed to be a distribution by the Company to the holders of its Shares of such class of stock and, if the outstanding Shares shallbe changed into a larger or smaller number of Shares as part of such reclassification, a Share Reorganization. (ii) If, at any time after the date hereof, the Company or any Subsidiary shall repurchase (a “Repurchase”), by self-tender offer or otherwise,any securities of the Company at an aggregate repurchase price that exceeds the aggregate Market Price for the securities repurchased determined as of theBusiness Day immediately prior to the earliest of (i) the date of such Repurchase, (ii) the commencement of an offer to repurchase or (iii) the publicannouncement of either (such date being referred to as the “Determination Date”), then the Exercise Price and the number of Warrant Shares issuable uponexercise of this Warrant shall be adjusted as follows: The Exercise Price shall be reduced to an amount equal to the product of (A) the Exercise Price in effect immediately prior to such issuanceor sale times (B) a fraction, (I) the numerator of which shall be (x) the product of (1) the Market Price for the Shares as of the DeterminationDate times (2) the number of Shares outstanding immediately following the consummation of the Repurchase less (y) the RepurchasePremium (as defined below), and (II) the denominator of which shall be (x) the product of (1) the Market Price for the Shares as of theDetermination Date times (2) the number of Shares outstanding immediately following the consummation of the Repurchase. The number of Warrant Shares issuable upon exercise of this Warrant shall be increased to the number of Shares determined by multiplying(x) the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to such distribution times (y) a fraction (1) thenumerator of which shall be the Exercise Price in effect immediately prior to the adjustment in clause (A) of this Section 4(c)(ii) and (2) thedenominator of which shall be the Exercise Price in effect immediately after such adjustment. 6 The amount by which the aggregate repurchase price for all securities repurchased in any Repurchase (including for such purposes any fees or otherdirect or indirect consideration payable in connection therewith) exceeds the aggregate Market Price for such securities is referred to as the “RepurchasePremium.” (d) Capital Reorganization. Without limiting any of the other provisions hereof, if any (i) capital reorganization; (ii) reclassification of the capitalstock of the Company; (iii) merger, consolidation or reorganization or other similar transaction or series of related transactions which results in the votingsecurities of the Company outstanding immediately prior thereto representing immediately thereafter (either by remaining outstanding or by being convertedinto voting securities of the surviving or acquiring entity) less than 50% of the combined voting power of the voting securities of or economic interests in theCompany or such surviving or acquiring entity outstanding immediately after such merger, consolidation or reorganization; (iv) sale, lease, license, transfer,conveyance or other disposition of all or substantially all of the assets of the Company; (v) sale of shares of capital stock of the Company, in a singletransaction or series of related transactions, representing at least 50% of the voting power of the voting securities of or economic interests in the Company; or(vi) the acquisition by any “person” (together with his, her or its Affiliates) or “group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act)acquires, directly or indirectly, the beneficial ownership (as such term is defined in Rule 13d-3 promulgated under the Exchange Act) of outstanding shares ofcapital stock and/or other equity securities of the Company, in a single transaction or series of related transactions (including, without limitation, one or moretender offers or exchange offers), representing at least 50% of the voting power of or economic interests in the then outstanding shares of capital stock of thecorporation (each of (i)-(vi) above a “Corporate Reorganization”) shall be effected, then the Company shall use its best efforts to ensure that lawful andadequate provision shall be made whereby each Warrant Holder shall thereafter continue to have the right to purchase and receive upon the basis and uponthe terms and conditions herein specified and in lieu of the Warrant Shares issuable upon exercise of the Warrants held by such Warrant Holder, shares ofstock in the surviving or acquiring entity (“Acquirer”), as the case may be, such that the aggregate value of the Warrant Holder’s warrants to purchase suchnumber of shares, where the value of each new warrant to purchase one share in the Acquirer is determined in accordance with the Black-Scholes OptionPricing formula set forth in Appendix (A) hereto, is equivalent to the aggregate value of the Warrants held by such Warrant Holder, where the value of eachWarrant to purchase one share in the Company is determined in accordance with the Black-Scholes Option Pricing formula set forth Appendix (B) hereto.Furthermore, the new warrants to purchase shares in the Acquirer referred to herein shall have the same expiration date as the Warrants, and shall have a strikeprice, KAcq, that is calculated in accordance with Appendix (A) hereto. For the avoidance of doubt, if the surviving or acquiring entity, as the case may be, isa member of a consolidated group for financial reporting purposes, the “Acquirer” shall be deemed to be the parent of such consolidated group for purposesof this Section 4(d) and Appendix (A) hereto. 7 Moreover, appropriate provision shall be made with respect to the rights and interests of each Warrant Holder to the end that the provisions hereof(including, without limitation, provision for adjustment of the Warrant Price) shall thereafter be applicable, as nearly equivalent as may be practicable inrelation to any shares of stock thereafter deliverable upon the exercise thereof. The Company shall not effect any such Corporate Reorganization unless priorto or simultaneously with the consummation thereof the successor corporation resulting from such consolidation or merger, or the corporation purchasing orotherwise acquiring such assets or other appropriate corporation or entity shall assume by written instrument, reasonably deemed by the Board of Directors ofthe Company and the Requisite Holders to be satisfactory in form and substance, the obligation to deliver to the holder of the Warrants, at the last address ofsuch holder appearing on the books of the Company, such shares of stock, as, in accordance with the foregoing provisions, such holder may be entitled topurchase, and the other obligations under these Warrants. The provisions of this Section 4(d) shall similarly apply to successive Corporate Reorganizations. Ifthe Company, in spite of using its best efforts, is unable to cause these Warrants to continue in full force and effect until the Expiration Date in connectionwith any Corporate Reorganization, then the Company shall pay the Warrant Holders an amount per Warrant to purchase one share in the Company that iscalculated in accordance with the Black-Scholes Option Pricing formula set forth in Appendix (B) hereto. Such payment shall be made in cash in the eventthat the Corporate Reorganization results in the Company or the shareholders of the Company receiving cash from the Acquirer at the closing of thetransaction, and shall be made in shares of the Company (with the value of each share in the Company is determined according to SCorp in Appendix (B)hereto) for all other Corporate Reorganizations. In the event that a Corporate Reorganization involves the payment of cash as well as other securities, suchpayment to the Warrant Holders shall be also be made in both cash and shares in the same proportion as the cash and non-cash portions of the considerations. (e) Adjustment Rules. (i) Any adjustments pursuant to this Section 4 shall be made successively whenever any event referred to herein shall occur, except that,notwithstanding any other provision of this Section 4, no adjustment shall be made to the number of Warrant Shares to be delivered to the Warrant Holder (orto the Exercise Price) if such adjustment represents less than 1% of the number of Warrant Shares previously required to be so delivered, but any lesseradjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which together with any adjustments socarried forward shall amount to 1% or more of the number of Warrant Shares to be so delivered. (ii) No adjustments shall be made pursuant to this Section 4 in respect of the issuance of Warrant Shares upon exercise of the Warrant; (iii) If the Company shall take a record of the holders of its Shares for any purpose referred to in this Section 4, then (x) such record dateshall be deemed to be the date of the issuance, sale, distribution or grant in question and (y) if the Company shall legally abandon such action prior toeffecting such action, no adjustment shall be made pursuant to this Section 4 in respect of such action. (iv) In computing adjustments under this Section 4, (A) fractional interests in Shares shall be taken into account to the nearest one-thousandth of a Share, and (B) calculations of the Exercise Price shall be carried to the nearest one-thousandth of one cent. 8 (f) Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustmentpursuant to this Section 4, the Company shall take any action which may be necessary, including obtaining regulatory approvals or exemptions, in order thatthe Company may thereafter validly and legally issue as fully paid and nonassessable all Shares which the Warrant Holder is entitled to receive upon exerciseof the Warrant. (g) Notice of Adjustment. Not less than 20 days prior to the record date or effective date, as the case may be, of any action which requires or mightrequire an adjustment or readjustment pursuant to this Section 4, the Company shall give notice to the Warrant Holder of such event, describing such event inreasonable detail and specifying the record date or effective date, as the case may be, and, if determinable, the required adjustment and computation thereof.If the required adjustment is not determinable as the time of such notice, the Company shall give notice to the Warrant Holder of such adjustment andcomputation as soon as reasonably practicable after such adjustment becomes determinable. In connection with any such adjustment or readjustment, at itssole cost and expense, the Company will also cause independent certified public accountants of recognized national standing (which may be the regularauditors of the Company) selected by the Company to verify its computations and, in connection with the preparation of the Company’s quarterly financialstatements prepare a report setting forth such adjustment or readjustment and showing in reasonable detail the method of calculation thereof and the factsupon which such adjustment or readjustment is based, including a statement of (i) the consideration received or to be received by the Company for any ShareDistribution issued or sold or deemed to have been issued, (ii) the number of Shares outstanding or deemed to be outstanding, and (iii) the Exercise Price ineffect immediately prior to such issue or sale and as adjusted and readjusted (if required by this Section 4) on account thereof. The Company will forthwithmail a copy of each such report to the Warrant Holder and will, upon the written request at any time of the Warrant Holder, furnish to such holder a like reportsetting forth the Exercise Price at the time in effect and showing in reasonable detail how it was calculated. The Company will also keep copies of all suchreports at its office and will cause the same to be available for inspection at such office during normal business hours by the Warrant Holder or anyprospective purchaser of this Warrant designated by the Warrant Holder. (h) Subsequent Warrants. Irrespective of any adjustments in the Exercise Price or the number of Warrant Shares issuable upon exercise of thisWarrant, any successor or replacement warrants issued theretofore or thereafter may continue to express the same Exercise Price per Share and number andkind of Warrant Shares as are stated in this Warrant. (i) Disputes. Any dispute which arises between the Warrant Holder and the Company with respect to the calculation of the adjusted Exercise Price orWarrant Shares issuable upon exercise shall be determined by the independent auditors of the Company, and such determination shall be binding upon theCompany and the holders of the Warrants and the Warrant Shares if made in good faith and without manifest error. 9 (j) Other Actions Affecting Shares. (i) Equitable Equivalent. In case any event shall occur as to which the provisions of this Section 4 set forth above hereof are not strictlyapplicable but the failure to make any adjustment would not, in the opinion of the Warrant Holder, fairly protect the purchase rights represented by thisWarrant in accordance with the essential intent and principles of this Section 4, then, in each such case, at the request of the Warrant Holder, the Companyshall appoint, at the Company’s expense, a firm of independent investment bankers of recognized national standing (which shall be completely independentof the Company and shall be satisfactory to the holder or the Requisite Holders), which shall give their opinion upon the adjustment, if any, on a basisconsistent with the essential intent and principles established in this Section 4, necessary to preserve, in an manner so as to reduce dilution, the purchaserights represented by this Warrant. Upon receipt of such opinion, the Company will promptly mail a copy thereof to the holder of this Warrant and shall makethe adjustments described therein. (ii) No Avoidance. The Company shall not, by amendment of its certificate of incorporation or by-laws or through any consolidation,merger, reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance orperformance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all suchaction as may be necessary or appropriate in order to protect the rights of the holder of this Warrant against unlimited dilution or other impairment as if theholder was a shareholder of the Company entitled to the benefit of fiduciary duties afforded to shareholders under Delaware law. (k) Calculation of Consideration Received. The consideration for the issue or sale of any Share Distribution shall, irrespective of the accountingtreatment of such consideration: (i) insofar as it consists of cash, be computed at the amount of cash actually received by the Company without reduction for any expensespaid or incurred by the Company or any commissions or compensations paid or concessions or discounts allowed to underwriters, dealers or othersperforming similar services in connection with such issue or sale; (ii) insofar as it consists of property (including securities) other than cash actually received by the Company, be computed at the AppraisedValue thereof at the time of such issue or sale; and (iii) insofar as it consists neither of cash nor of other property, be computed as having no value. (l) Adjustment of Par Value. If for any reason (including the operation of the adjustment provisions set forth in this Warrant), the Exercise Price onany date of exercise of this Warrant shall not be lawful and adequate consideration for the issuance of the relevant Warrant Shares, then the Company shalltake such steps as are necessary (including the amendment of its certificate of incorporation so as to reduce the par value of the Shares) to cause such ExercisePrice to be adequate and lawful consideration on the date the payment thereof is due, but if the Company shall fail to take such steps, then the Companyacknowledges that the Warrant Holder shall have been damaged by the Company in an amount equal to an amount, which, when added to the total ExercisePrice for the relevant Warrant Shares, would equal lawful and adequate consideration for the issuance of such Warrant Shares, and the Company irrevocablyagrees that if the Warrant Holder shall then forgive the right to recover such damages from the Company, such forgiveness shall constitute, and Companyshall accept such forgiveness as, additional lawful consideration for the issuance of the relevant Warrant Shares. 10 (m) Appraisal. (i) If the Requisite Holders shall, for any reason whatsoever, disagree with the Company’s determination of the Appraised Value of a Share,then such holders shall by notice to the Company (an “Appraisal Notice”) given within sixty (60) days after the Company notifies the holders of suchdetermination, elect to dispute such determination, and such dispute shall be resolved as set forth in clause (ii) of this Section. (ii) The Company shall within ten (10) days after an Appraisal Notice shall have been given, engage an independent investment bank ofnational repute (the “Appraiser”) selected by the Requisite Holders and retained pursuant to an engagement letter between the Company and the Appraiserwith respect to such valuation in form and substance reasonably acceptable to Requisite Holders, to make an independent determination of the AppraisedValue of a Share; such value shall be determined without deduction for (a) liquidity considerations, (b) minority shareholder status, or (c) any liquidation orother preference or any right of redemption in favor of any other equity securities of the Company. The costs of engagement of such investment bank for anysuch determination of Appraised Value shall be paid by the Company. Section 5. [Reserved]. Section 6. Transfer of Warrant.

Section 7. Assistance in Disposition of Warrant or Warrant Shares. Notwithstanding any other provision herein, in the event that it becomes unlawfulfor the Warrant Holder to continue to hold the Warrant, in whole or in part, or some or all of the Shares held by it, or restrictions are imposed on any theWarrant Holder by any statute, regulation or governmental authority which, in the judgment of the Warrant Holder, make it unduly burdensome to continueto hold the Warrant or such Shares, the Warrant Holder may sell or otherwise dispose of the Warrant (subject to the restrictions on transfer provided in Section6) or its Shares, and the Company agrees to provide reasonable assistance to the Warrant Holder in disposing of the Warrant and such Shares in a prompt andorderly manner and, at the request of the Warrant Holder, to provide (and authorize the Warrant Holder to provide) financial and other informationconcerning the Company to any prospective purchaser of the Warrant or Shares owned by the Warrant Holder. 11 Section 8.
