|ITEM 1. | BUSINESS
|------- | --------

In addition to historical facts or statements of current conditions, our disclosure and analysis in this
Form 10-K contain some forward-looking statements. See the discussion of forward-looking statements in Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operation included in this Form
10-K.

Unless the context indicates otherwise, the terms Orthovita, Company, we, us or our
herein refers to Orthovita, Inc. and, where appropriate, one or more of our subsidiaries.

GENERAL DEVELOPMENT OF OUR BUSINESS

We are a spine and orthopedic biosurgery company with proprietary biomaterials and biologic technologies for the development and commercialization of synthetic,
biologically active, tissue engineering products. We develop and market synthetic-based biomaterial products for use in spine surgery, the repair of fractures and a broad range of clinical needs in the trauma, joint reconstruction, revision and
extremities markets. We also market accessories and delivery products that complement our biomaterials platforms.

Our near-term commercial business is based on our VITOSS® Bone Graft Substitute technology platforms, which are designed to address the non-structural bone
graft market by offering synthetic alternatives to the use of autograft or cadaver-based bone material, and VITAGEL® Surgical Hemostat, which is an adherent matrix and an impermeable
barrier to blood flow. Our longer-term U.S. clinical development program is focused on our internally developed CORTOSS® Bone Augmentation Material technology platform, which is primarily
designed for injections into osteoporotic spines to treat vertebral compression fractures (VCFs).

In addition, we employ in-house research and
development in support of biomaterial and biologic technology platforms. We also work jointly with Kensey Nash Corporation (Kensey) to develop and commercialize synthetic-based biomaterial products, and we market VITAGEL under a license
granted by Angiotech Pharmaceuticals (U.S.), Inc. (collectively with its affiliates and parent company Angiotech Pharmaceuticals, Inc., Angiotech), and we continue to pursue similar relationships with other biomaterials companies.

We incorporated in Pennsylvania in 1992 and maintain a branch operation in Belgium, as well as a wholly-owned subsidiary incorporated in Delaware to hold
certain intangible properties and a wholly-owned subsidiary incorporated in Pennsylvania for certain non-U.S. sales activities.

Kensey Agreement

In March 2003, we entered into an agreement with Kensey to jointly develop and commercialize certain biomaterials-based products based upon our
VITOSS platform. The new products developed under this agreement are based on our internally developed, proprietary VITOSS bone void filler material in combination with proprietary resorbable Kensey biomaterials. To date, the products covered by the
Kensey agreement for which we have received 510(k) clearance from the U.S. Food and Drug Administration (FDA) are our VITOSS FOAM and Bioactive

VITOSS FOAM products.

Kensey has the exclusive right to
manufacture any approved or cleared jointly developed product under the agreement, and we market and sell the product worldwide. Following the regulatory approval or clearance of each new product under the agreement, we have obligations to pay
Kensey for manufacturing the product and make royalty payments to Kensey based on the net sales of such product. These rights and obligations extend until at least February 2024 for our Bioactive VITOSS FOAM product, and until February 2014 for our
other products under the VITOSS FOAM product platform.

Approximately 61% of our product sales during the year ended December 31, 2007 was from
products based upon our VITOSS FOAM platform co-developed with Kensey.

Angiotech Agreements

In June 2004, we entered into a Distribution Agreement with Angiotech to distribute to surgical customers
throughout North America the CoStasis® composite liquid hemostat (which we re-branded as VITAGEL Surgical Hemostat) and the CELLPAKER® plasma collection system used in conjunction with VITAGEL. The Distribution Agreement required us to purchase the products and make royalty payments to Angiotech based on the net sales of such products. Effective September 30, 2005, the
Distribution Agreement was amended to provide for the transition of product and accessory manufacturing responsibility from Angiotech to us. The amendment also changed the royalty rate payable by us to Angiotech and modified the method for
calculating net sales of such products. When Angiotech decided to cease the manufacture of VITAGEL and CELLPAKER, we purchased all available existing VITAGEL and CELLPAKER products, accessories and work-in-process from Angiotech in October 2005 for
$1,800,000. On June 16, 2006, we obtained pre-market approval (PMA) from the FDA to sell VITAGEL manufactured at our Malvern, Pennsylvania facility (the VITAGEL PMA). After receiving the VITAGEL PMA, we started
manufacturing VITAGEL in July 2006, and in August 2006 we commenced selling VITAGEL first manufactured since obtaining the VITAGEL PMA. In addition, we had previously manufactured under the VITAGEL PMA three lots of VITAGEL that became available for
sale in late June 2006. In January 2007, we obtained approval from the FDA for a PMA supplement which enables us to sell CELLPAKER manufactured by our subcontractors facility. Effective January 1, 2006, we entered into a License Agreement
with Angiotech pursuant to which Angiotech licensed VITAGEL products and the CELLPAKER plasma collection system to us and we assumed manufacturing responsibility for these products. The Distribution Agreement described above served as the basis for
the establishment of the License Agreement. In accordance with its terms, the Distribution Agreement terminated in the first quarter of 2007 upon completion of the sale of all VITAGEL and CELLPAKER inventory products that we purchased from Angiotech
in October 2005. Until December 29, 2006, we paid royalties on sales of the VITAGEL and CELLPAKER inventory that we purchased from Angiotech in October 2005 in accordance with the terms of the Distribution Agreement.

On December 29, 2006, pursuant to a Royalty Sale Agreement with Angiotech, we purchased the profit-sharing royalty rights for VITAGEL and CELLPAKER products under
the License Agreement for $9,000,000 in cash. As amortization of the $9,000,000 royalty prepayment, we recorded non-cash amortization expense of $850,000 in 2007, and anticipate that we will record an annual non-cash amortization expense of at least
$850,000 in each year thereafter through July 31, 2017.

Concurrently with such purchase, we entered into an Amended and Restated License Agreement with Angiotech that amended the original License Agreement to
eliminate our obligations to meet minimum sales requirements, extend the term of the license from December 31, 2014 through July 31, 2017, and eliminate certain termination rights in favor of Angiotech. Under the Amended and Restated
License Agreement, we have exclusive rights to manufacture and sell VITAGEL products throughout the world for orthopedic indications, and non-exclusive rights to manufacture and sell CELLPAKER products throughout the world for all indications. Under
the Amended and Restated License Agreement, Angiotech has an option for co-exclusive rights outside the orthopedic field which, if exercised, would permit Angiotech to manufacture and sell an Angiotech-branded VITAGEL product throughout the world.
Until Angiotech elects to exercise its option for co-exclusive rights, we have exclusive rights to manufacture and sell VITAGEL outside of the orthopedic field throughout the world. If Angiotech elects to exercise its option, we would then have
co-exclusive rights to manufacture and sell VITAGEL outside of the orthopedic field throughout the world. Prior to the amendment and restatement of the License Agreement on December 29, 2006, we were required to make royalty payments thereunder
based on a share of all revenue we received from net sales of VITAGEL and CELLPAKER products that we manufactured.

VITOMATRIX Supply Agreement

In August 2002, we entered into a supply agreement with BioMimetic Therapeutics, Inc. that enables BioMimetic to use its recombinant human platelet
derived growth factor (rhPDGF) in combination with our proprietary VITOMATRIX particulate synthetic scaffold biomaterial, which we produce in the same process used to manufacture VITOSS. Under the agreement, we supply our
proprietary beta tricalcium phosphate biomaterial to BioMimetic for its clinical and commercial use in conjunction with its rhPDGF. The agreement provides that BioMimetic may market and sell the combined product in the dental, periodontal, oral and
cranio-maxillofacial bone grafting markets. In January 2008, in connection with the sale of its dental business to Luitpold Pharmaceuticals, Inc., BioMimetic assigned its rights and obligations under the supply agreement to Luitpold. Accordingly, we
will supply VITOMATRIX to Luitpold in accordance with the terms of the supply agreement.

Other Sales and Corporate Information

We market and sell our VITOSS products, the IMBIBE®
Bone Marrow Aspiration and Delivery Devices (used with VITOSS) and VITAGEL and CELLPAKER products through a U.S. field sales network of direct sales representatives and independent distributors that we began to assemble in June 2003. As of
December 31, 2007, we had approximately 83 direct sales representatives and arrangements with approximately 30 independent distributors that we utilize to market our products. We continue to strengthen our field sales network through the
addition of direct sales representatives in those U.S. sales territories where either we do not have independent distributor coverage or the territories are underserved. Outside of the U.S., we primarily utilize a network of independent stocking
distributors to market VITOSS, CORTOSS and the ALIQUOT® Delivery System (a system designed to facilitate effective delivery of our CORTOSS product), and VITAGEL and CELLPAKER products.

body guide the three-dimensional regeneration of the patients own bone. We launched VITOSS in the U.S. and the EU in 2001 and have sold approximately
200,000 units through December 31, 2007. VITOSSs ultra-porosity allows it to soak and hold its own volume in blood and bone marrow aspirate and has been shown to perform well in an array of applications in the spine, extremities and
pelvis, such as spinal grafting and the treatment of bone defects due to trauma, degenerative disease and tumors. VITOSS integrates well into existing bone and allows for bone in-growth and maturation. VITOSS, the VITOSS FOAM products and the
Bioactive VITOSS FOAM products are covered by issued and pending U.S. and foreign patents.

Since the initial U.S. regulatory clearance and subsequent
product launch in mid-2001, we have developed and are developing a number of new VITOSS-based products and related delivery devices that are designed to expand the market for our VITOSS products by broadening the range of surgical indications and by
addressing additional surgeon preferences and needs. In 2003, we entered into a development, manufacturing and supply agreement with Kensey, which led to the development and launch of the VITOSS FOAM product platform. The VITOSS FOAM products
combine our base VITOSS technology with Kenseys proprietary resorbable biomaterials to produce a wide array of pliant, flexible, flowable and compression resistant bone graft materials. The VITOSS FOAM products have the ability to soak and
hold their own volume in blood and bone marrow aspirate while retaining these biological fluids in pliable and compression resistant forms. These forms can be designed into specific shapes and material characteristics to meet a surgeons need
for handling and delivery in a variety of surgical approaches and applications. We launched our Bioactive VITOSS FOAM product as part of a controlled rollout in the first quarter of 2008, and expect to fully launch the product during the second
quarter of 2008. In addition to our proprietary VITOSS beta-tricalcium phosphate bone graft substitute and Kenseys proprietary resorbable biomaterials, VITOSS Bioactive FOAM also contains ours proprietary combeite bioactive glass.

Bone Defect Grafting. Injury or trauma to the bone, degenerative conditions, disease and aging all affect the health and viability of the human skeleton. These
conditions often result in the need for the repair of bone defects through a bone grafting procedure. We estimate that approximately 1,000,000 bone grafting procedures on a worldwide basis are performed each year in the spine, extremities and
pelvis. Bone grafting material is either (i) autograft material, which is often obtained or harvested from the iliac crest region of the patients own hip, (ii) allograft material, which is obtained from a cadaver, or
(iii) synthetically derived materials that provide one or more components of either bone-like scaffold (such as VITOSS), cells or signals (such as bone morphogenic proteins). VITOSS has been used in bone grafting procedures as a bone graft
substitute to provide a synthetic scaffold in a variety of applications, including those of the extremities, spine and pelvis. When used with the patients bone marrow, VITOSS provides all components of scaffold, cells and signals.

A harvest of autograft material involves an additional procedure that extends surgical time, adding to costs and increasing blood loss and patient risk of infection
or adverse reaction from the additional time under anesthesia. In addition, harvesting bone for autograft sometimes causes protracted pain that may necessitate additional medical care after the surgical procedure. Using VITOSS instead of autograft
material may avoid these potential complications.

Disadvantages of allograft bone include the possibility of disease transmission, antigenic response and
quality variability from donor to donor. VITOSS is a synthetic beta-tricalcium

phosphate material without these possible disadvantages.

Spinal Grafting. Many patients affected by severe back pain due to degeneration of one or more discs are treated with a spinal surgical procedure. We estimate that each year approximately 500,000 spinal surgical procedures are done
on a worldwide basis. In cases where the patient has advanced disc degeneration or spinal instability, a spinal surgical procedure may involve a surgical incision in the patients back or abdomen and frequently requires the removal of the
affected disc material and the surgical attachment of a metal implant, spinal fusion cage, or machined bone derived from a cadaver to provide the initial support and intrinsic stability of the bony structure for the two surrounding vertebrae. Such
spinal surgical procedures may require the use of a bone grafting material to help treat any surgically created bony defects. We believe the use of VITOSS as a bone void filler, rather than allograft or autograft materials, in spinal grafting
procedures may be preferable for both the patient and the surgeon.

Trauma. Physical trauma such as falls and accidents can result in bone fracture
or damage. Fractures of broken bones are often realigned with hardware, such as plates, rods and screws. Once the hardware has been used to recreate the skeletal anatomy and to provide the stability of the bony structure, there are often defects or
voids in the bone which remain. Those voids may require the use of bone graft material. The goal of bone grafting in trauma applications is to rapidly heal the damaged bone. Approximately 100,000 trauma related bone graft repairs are performed
annually on a worldwide basis. Autograft, cadaver allograft, as well as synthetic scaffolds like VITOSS, are used for trauma related bone graft repairs. VITOSS has been used as a bone graft substitute in a variety of trauma applications, including
those of the extremities, spine and pelvis.

Dental, Periodontal, Oral and Cranio-Maxillofacial. In August 2002, we entered into a supply agreement
with BioMimetic Therapeutics, Inc. for our proprietary VITOMATRIX particulate synthetic scaffold biomaterial, which we produce in the same process used to manufacture VITOSS. In January 2008, in connection with the sale of its dental business to
Luitpold Pharmaceuticals, Inc., BioMimetic assigned its rights and obligations under the supply agreement to Luitpold. Under the agreement, we supply our proprietary beta tricalcium phosphate biomaterial to Luitpold for its clinical and commercial
use in combination with rhPDGF. Luitpold markets the combined product in the dental, periodontal, oral and cranio-maxillofacial bone grafting markets through its Osteohealth Company division.

VITAGEL is an FDA-approved, CE-marked composite liquid hemostat that combines the biomaterials bovine thrombin and
bovine collagen with the patients autologous plasma. When applied to the surgical site, VITAGEL creates a safe adherent matrix and an impermeable barrier to blood flow. VITAGEL has been marketed to general surgeons and is applicable in the
spine, hip and knee replacement surgery markets, where bleeding is a significant complication for many routine surgeries. After initially obtaining the right to sell CoStasis from Angiotech in June 2004, we rebranded CoStasis as VITAGEL Surgical
Hemostat in January 2005 with CELLPAKER accessories, and relaunched the product in the U.S. within our existing orthopedics and spine-based sales channel, utilizing the same marketing strategy that we use for all of our VITOSS-related products. This
strategy provides our sales network additional functional biomaterial products to offer to customers. During the first half of 2006, we launched the VITAGEL Spray Set in the U.S. We obtained the CE Mark for VITAGEL, CELLPAKER and related accessories
in July 2007 and launched these products in the European Union in the first quarter of 2008. VITAGEL and CELLPAKER are covered by U.S. and foreign issued patents owned by our licensor Angiotech.

Near-Term Product Development

We have developed and are continuing
to develop new products under our approved VITOSS, VITAGEL and IMBIBE product platforms. We may seek to bring VITOSS, VITAGEL and/or

IMBIBE product line extensions to market in the U.S. through the 510(k) or PMA regulatory process (see Government Regulation below). These product line
extensions will be in addition to our U.S. CORTOSS investigational device exemption (IDE) clinical program, which is described below.

CORTOSS Bone Augmentation Material

CORTOSS is a self-setting glass ceramic polymeric composite engineered specifically to mimic the
characteristics of human bone. Laboratory tests demonstrate that CORTOSS exhibits compressive strength similar to human bone. For patients with poor bone healing, as seen in osteoporotic patients, CORTOSS may be used in a variety of surgical
procedures to quickly provide structural stability and reinforcement of the bones after surgery. The surgeons goal is to repair the patients bone and enhance the patients mobility as quickly as possible since prolonged bed rest or
inactivity may result in decreased overall health for older or osteoporotic patients.

CORTOSSs simple mix-on-demand delivery system design allows
for minimum waste and maximum ease of use and flexibility for the surgeon. CORTOSS is an injectable material that is delivered through a pre-filled, unit dose, disposable cartridge. Delivery of CORTOSS to the surgical site may be started and stopped
for a prolonged period of time throughout the surgical procedure as polymerization is initiated only when CORTOSS is expressed through its static mix-tip. The polymerization is a self-setting reaction that causes CORTOSS to harden within minutes.
CORTOSS provides two stages of fixation: immediate mechanical interlock into porous bone, followed by intimate bone growth over time along the contours of its surface. CORTOSS is covered by several U.S. issued patents and other U.S. and foreign
patent applications are pending.

We received CE Certification for CORTOSS for use in screw augmentation procedures in October 2001 in the EU and
regulatory approval in March 2001 in Australia, which enables us to sell CORTOSS in these territories as well as in other countries that have adopted the EUs regulatory standards. Screw augmentation is a procedure for securing the fixation of
bone screws used in patients with weak bone caused by osteoporosis. We initiated a limited launch of CORTOSS in Europe in December 2001. We successfully completed post-marketing human clinical studies in Europe for the use of CORTOSS in hip
compression screw augmentation. In addition, during January 2003, we received CE Certification in the EU to market CORTOSS for vertebral augmentation of VCFs of the spine. Vertebral augmentation of VCFs is a procedure for repairing fractured
vertebrae that can be performed on an outpatient or short-stay basis. We have sold approximately 10,000 units of CORTOSS through December 31, 2007. During 2003 and 2004, we completed patient enrollment of two FDA-approved IDE pilot clinical
studies in the U.S. for the use of CORTOSS in vertebral augmentation of VCFs using the vertebroplasty and kyphoplasty surgical techniques, respectively. The two pilot studies were completed in 2007. Both surgical techniques involve the injection of
a self-setting material into the vertebral body to provide internal fixation of the VCF. Upon FDA review of the vertebroplasty pilot clinical data, we received approval from the FDA to begin patient enrollment in a prospective, randomized controlled
pivotal phase of that clinical study. See GOVERNMENT REGULATION  CORTOSS below for more information about the design of the pivotal study. The pivotal study was fully enrolled as of February 21, 2007 with 162 CORTOSS patients
and 94 polymethylmethacrylate (PMMA) patients. Patients will be followed at predetermined

intervals and annually until the 24-month post-procedure period for the last-enrolled patient, which is scheduled to occur in February 2009. In January 2008,
we submitted to the FDA a 510(k) application for the use of CORTOSS in vertebral augmentation (see GOVERNMENT REGULATION below). FDA clearance of CORTOSS would permit Orthovita to market and sell the material in the United States.

Vertebral Augmentation of VCFs. We estimate there are approximately 700,000 patients in the U.S. with VCFs caused by osteoporotic bone or bone cancer resulting in
severe pain and immobility. Of these, we believe approximately 260,000 fractures are diagnosed. The traditional treatments, e.g., bed rest, bracing, narcotics or anesthetic injections, do not address the underlying fracture. Vertebral augmentation
of VCFs has been reported to provide early pain relief in over 90% of osteoporotic patients. Early relief of pain provided by vertebral augmentation of VCFs enables patients to maintain better functional capacity. Functional capacity, in turn, is
believed to be directly related to the ability to live independently and unassisted. We are not aware of any product that has received FDA approval or CE Certification for use in this procedure on the basis of prospective, controlled clinical data.
However, since 2004, several versions of PMMA bone cement have been 510(k) cleared by the FDA. We believe CORTOSS may have several advantages over PMMA in vertebral augmentation of VCFs, such as its lower temperature setting that reduces the risk of
tissue necrosis associated with PMMA, its higher compression strength and its ability to be mixed on demand. In addition, unlike PMMA, CORTOSS does not release volatile free unreacted methylmethacrylate monomer into the patients body.
Published data reports that monomer release has been shown to cause a variety of cardiopulmonary complications such as hypotension and emboli in the lungs and brain. Although these documented complications may be rare, they are severe adverse events
when they occur.

Screw Augmentation. Worldwide each year, we estimate approximately 1,500,000 orthopedic procedures are performed using internal
fixation devices that involve screws, including pedicle, trauma and hip fracture screws. CORTOSS may be used in those procedures where the screws strip or fail to hold the integrity of the internal fixation construct due to poor bone
quality, as is often the case with osteoporotic bone. Where screws fail to hold, current treatment options include: (i) replacing the screw with a screw of larger diameter, which may further weaken the bone and is not always possible because of
the size of the screw holes and/or the bone, or (ii) augmenting the screws with PMMA bone cement, which is cumbersome and time consuming. PMMA must be manually mixed and transferred into a syringe for application. After mixing, there is only a
small time window in which the PMMA can be used before it sets, making it difficult to augment more than one screw at a time. Additionally, PMMA bone cement is not approved in either Europe or the U.S. for pedicle, trauma or hip fracture screw
augmentation. We believe the use of CORTOSS to anchor the screw in a quick and efficient way enables the full function of the screw to be restored. We are not aware of any cement products that have received FDA approval or CE Certification that
would be in competition with CORTOSS for these indications.

ALIQUOT Delivery System

Our ALIQUOT Delivery System facilitates delivery of materials to bony sites, including delivery of our CORTOSS product directly to the surgical site. A coaxial system of catheter and syringe dispenser is designed to
assure effective delivery of material in vertebral augmentation of VCFs

and screw augmentation procedures. During the second quarter of 2002, we received CE Certification from our Notified Body for certain ALIQUOT kit
configurations. The ALIQUOT system was used as part of our European multi-center prospective clinical study for CORTOSS in vertebral augmentation of VCFs and was used in the U.S. clinical studies for CORTOSS in vertebral augmentation of VCFs. In
February 2008, we submitted to the FDA a 510(k) application for the use of certain ALIQUOT kit configurations in the delivery of bone augmentation material or bone cement legally cleared for use in orthopedic procedures such as for the treatment of
compression fractures of a vertebral body. ALIQUOT is covered by issued and pending U.S. and foreign patents.

Our strategy is to seek protection for our product technologies and manufacturing methods through the use of U.S. and foreign patents. We have filed or intend to file
applications as appropriate for patents covering our technologies, products and processes. As of the date of this filing, certain of the products that we have developed and marketed are covered by one or more of our twenty issued U.S. patents,
sixteen pending U.S. patent applications and numerous counterparts of certain of these patents and pending patent applications outside the U.S., including Canada, Europe, Mexico and Japan. Our issued patents are set to expire between 2015 and 2021.

MANUFACTURING AND PRODUCT SUPPLY

The manufacture of
our products is subject to regulation and periodic inspection by various regulatory bodies for compliance with current FDA Quality System Regulations, EU Medical Devices Directive, International Organization for Standardization (ISO)
9000 Series standards, ISO 13485/European Norm (EN) 13485 and equivalent requirements.

In-House Manufacturing. Our 24,800-square foot
VITOSS, VITAGEL and CORTOSS

##### Table of Contents

manufacturing facilities that produce our commercial products are leased through July 2012 and are certified as meeting the requirements of ISO 9000: 2000
and EN 13485 for the period July 1, 2006 through July 1, 2009. These facilities are subject to inspection by the FDA for compliance with FDA device manufacture requirements. We believe our existing manufacturing facilities have the
capacity to meet our commercial needs into 2010. In the fourth quarter of 2006, we commenced renovations at sites we currently lease to expand our capacity to manufacture our products. We expect to complete these renovations and submit a PMA
supplement with the FDA for this renovated facility in the second quarter of 2008. We also have plans to start processing collagen for VITAGEL in-house within the next two years since our supplier of collagen for VITAGEL notified us in 2007 of its
intent to shut down its collagen-processing facility and cease supplying us with this collagen raw material (see  Raw Materials Supply below). We accordingly commenced additional renovations in the first quarter of 2008 at sites we
currently lease to establish a 10,700-square foot facility to process collagen used in the manufacture of our VITAGEL product. We expect to complete these renovations by the first quarter of 2009 and to submit a PMA supplement with the FDA for this
renovated facility in the second quarter of 2009. We cannot market commercial products made at these facilities until any requisite PMA supplements have been approved by the FDA (see GOVERNMENT REGULATION below).

Third Party Manufacturers. We are manufacturing CELLPAKER, IMBIBE and ALIQUOT through outside third-party contract manufacturers. Our VITOSS is converted to
VITOSS FOAM and Bioactive VITOSS FOAM by Kensey, our development partner under a long term supply agreement. Our third-party manufacturers are regulated by government agencies and are required to be ISO 9001/EN 13485 certified or otherwise meet our
quality system requirements (See GOVERNMENT REGULATION below).

Raw Materials Supply. Our ability to manufacture our products is
dependent on a limited number of specialty suppliers of certain raw materials.

In November 2007, we entered into a supply and license agreement with
Allergan, Inc. and Allergan Sales, LLC (collectively, Allergan) to acquire raw material, equipment and a technology license from Allergan for an aggregate purchase price of approximately $6.6 million in cash. We expect to make the
purchase price payment in a lump sum on or about October 31, 2008. The raw material, equipment and license to be acquired from Allergan relate primarily to the production of our VITAGEL product. Under the agreement, Allergan will manufacture
and supply specified quantities of collagen to us no later than October 31, 2008. These quantities are in addition to collagen supplied by Allergan to us in the fourth quarter of 2007 under a prior supply arrangement. Additionally, under the
supply and license agreement, Allergan agreed to sell us certain collagen production and test equipment and grant us a non-exclusive, perpetual, royalty-free, irrevocable license to certain collagen production process technology and know-how. The
license rights are limited to certain uses, including those related to the processing and production of collagen for surgical hemostats. We expect delivery of all of the equipment by the fourth quarter of 2008 and to commence in-house processing of
collagen for VITAGEL by the first quarter of 2009. However, we must receive the requisite regulatory approvals for a collagen processing facility before we may sell VITAGEL containing collagen processed at a new facility. We do not expect to receive
any such approval prior to 2010. We believe the strategic collagen reserve for VITAGEL to be acquired under the supply and license agreement will be sufficient to

##### Table of Contents

meet our needs for VITAGEL through the first half of 2010.

We
also have a supply agreement with Kensey for bovine collagen used in our VITOSS FOAM and Bioactive VITOSS FOAM product lines.

We do not have any other
supply agreements for raw materials. The failure of any supplier to continue to provide us with materials at a price or quality acceptable to us, or at all, or our inability to find an alternative supplier with acceptable prices and quality, would
have a material adverse effect on our ability to manufacture our products.

SALES AND MARKETING

In June 2003, we began to assemble a U.S. field sales network of direct sales representatives and independent non-stocking distributors who now market VITOSS, VITAGEL,
CELLPAKER and IMBIBE. We continually seek to strengthen our field sales network through the addition of direct sales representatives in those U.S. sales territories where either we do not have independent distributor coverage or the territories are
underserved. Outside of the U.S., we primarily utilize a network of independent, stocking distributors to market VITOSS, CORTOSS, ALIQUOT, VITAGEL and CELLPAKER.

COMPETITION

Extensive research efforts and rapid technological change characterize the market for products in the orthopedic market. We
face intense competition from medical device, biomedical technology, and medical products companies. Our products could be rendered noncompetitive or obsolete by competitors technological advances. We may be unable to respond to technological
advances through the development and introduction of new products. Moreover, many of our existing and potential competitors have substantially greater financial, marketing, sales, distribution, manufacturing and technological resources than us.
These competitors may also be in the process of seeking FDA or other regulatory approvals, or patent protection, for new products. Our competitors could, therefore, commercialize new competing products in advance of our products. There can be no
assurance that we will be able to compete successfully against current or future competitors or that competition will not have a material adverse effect on our business, financial condition and results of operations.

We believe VITOSS faces competition from numerous synthetic, bone morphogenic proteins (BMPs) and cadaver-based products, such as demineralized bone matrix (DBM)
products, currently on the market that may be used for the same indications as our products as well as other products and technologies that may enter the market in the future. In 2004, lumbar total disc replacement (TDR) devices were introduced in
the spinal market as a treatment alternative for degenerative disc disease designed to preserve the motion of the vertebrae of the spine. However, we believe that several factors may mitigate against the broad use of lumbar TDR devices, including
the need for surgeon training, the high level of surgeon technical skills required, surgeon concern regarding the challenges of TDR revision surgery should that become necessary due to loosening or subsidence of the device over time, and procedure
reimbursement. In 2007, cervical TDR devices were introduced in the spine market. As they may require a lower level of surgical technical skill than lumbar TDR devices, cervical TDR devices could become more widely adopted than lumbar TDR devices.
TDR devices, particularly cervical TDR devices,

could negatively impact the spinal fusion market which could in turn adversely impact the use of VITOSS in spine grafting procedures. It is too early to
estimate the rate at which the market will ultimately adopt this or comparable technology as a treatment alternative or its resulting impact on our products.

VITAGEL is approved by the FDA as a surgical hemostat where bleeding may be a significant complication for many routine surgeries. As such, VITAGEL can be marketed broadly to general surgeons and is applicable in the spine, hip and
knee replacement surgery markets. VITAGEL faces competition from several more established surgical hemostat products marketed by other companies with substantially greater resources than us. However, we believe VITAGEL offers unique advantages in
comparison to these other products in terms of VITAGELs quick and easy preparation for use, as well as its use of the patients autologous plasma instead of pooled donated human plasma as is the case with the leading products in the
market. In 2008, recombinant human thrombin was approved for sale in the U.S. We believe that recombinant human thrombin will be positioned as an improvement to bovine-derived thrombin, a raw material in our VITAGEL product, which could adversely
affect our sales of VITAGEL. It is too early to estimate the effect of this new technology on our VITAGEL product. If management believes this effect to be material and adverse to our VITAGEL sales, it will consider alternative formulations of
VITAGEL and the regulatory approvals that may be required for any such alternative formulations.

CORTOSS is under clinical development in the U.S. for use
in the vertebral augmentation of VCFs and has received CE Certification for use in vertebral augmentation of VCFs and in screw augmentation. If CORTOSS is cleared by the FDA for use in vertebral augmentation of VCFs, it will face competition from
the several PMMA bone cement products that have been 510(k) cleared by the FDA since 2004 for this indication. Outside the U.S., CORTOSS is facing competition from several other PMMA bone cement products that have received CE Certification since
2004 for this indication. We do not know of any products that have received FDA approval or a CE Certification for use in screw augmentation or for which such approval is being sought.

GOVERNMENT REGULATION

In order to market our products, we must apply for, be granted and maintain all necessary
regulatory approvals, clearances and certifications. In addition, we must comply with all regulatory requirements in each applicable jurisdiction. We have received 510(k) regulatory clearance in the U.S. from the FDA in December 2000, and CE
Certification in the EU from our Notified Body in July 2000, for VITOSS. We also received regulatory approval to sell VITOSS in Australia and Canada in March 2001 and June 2004, respectively. The CE Certification permits us to sell our approved
products in all of the countries of the EU as well as in other countries, such as Switzerland and Israel, that have mutual recognition agreements with the EU or have adopted the EUs regulatory standards. We received 510(k) regulatory clearance
for VITOSS Canisters and VITOSS FOAM in November and December 2003, respectively, in the U.S. from the FDA. We received 510(k) regulatory clearance for Bioactive VITOSS FOAM in September 2007. In September 2001 and June 2005, we received 510(k)
regulatory clearance in the U.S. from the FDA to market our IMBIBE product for use as a bone marrow aspiration syringe and needle, respectively. In July 2007, we received CE Certification for VITAGEL and CELLPAKER, which products are covered by PMA
approvals from the FDA obtained by our

licensor of such products.

CORTOSS

We received CE Certification for CORTOSS in October 2001 in the EU and regulatory approval in March 2001 in Australia, which enables us to sell CORTOSS in these
territories for use in securing the fixation of bone screws in patients with weak bone caused by osteoporosis. In addition, during January 2003 our CE Certification was extended to enable us to market CORTOSS in the EU for vertebral augmentation of
VCFs, including compression fractures of the spine caused by osteoporosis and invasive tumors. During the second quarter of 2002, we received CE Certification from our Notified Body for ALIQUOT, which facilitates delivery of CORTOSS.

During 2003 and 2004, we completed patient enrollment of two FDA-approved IDE pilot clinical studies in the U.S. for the use of CORTOSS in vertebral augmentation of VCFs
using the vertebroplasty and kyphoplasty surgical techniques, respectively. The two pilot studies were completed in the third quarter of 2007. Both surgical techniques involve the injection of a self-setting material into the vertebral body to
provide internal fixation of the VCF. Upon FDA review of the vertebroplasty pilot clinical data, we received approval from the FDA to begin patient enrollment in a prospective, randomized controlled pivotal phase of that clinical study. The study
design was subsequently amended and approved by the FDA in August 2004 to allow the comparison of CORTOSS to a treatment arm using PMMA bone cement instead of a non-treatment arm consisting of conservative care and pain management. In February 2007,
we completed enrollment of the pivotal CORTOSS study, which was conducted under an FDA Investigational Device Exemption (IDE). A total of 256 patients were enrolled in the pivotal study with a randomization of approximately 2:1 (162 patients treated
using CORTOSS and 94 patients treated using a PMMA bone cement) at 22 sites. Patients will be followed at predetermined intervals and annually until the 24-month post-procedure period for the last-enrolled patient, which is scheduled to occur in
February 2009. In January 2008, we submitted to the FDA a 510(k) application for the use of CORTOSS in vertebral augmentation. FDA clearance of CORTOSS would permit Orthovita to market and sell the material in the United States.

The following discussion summarizes the regulatory requirements applicable to our products.

United States

The medical devices that we manufacture and market, or intend to market, are subject to extensive regulation
by the FDA. Pursuant to the Federal Food, Drug and Cosmetic Act (FFD&C Act) and the regulations promulgated thereunder, the FDA regulates the clinical testing, manufacture, labeling, distribution and promotion of medical devices.
Noncompliance with applicable requirements can result in, among other things, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the government to grant premarket clearance or
premarket approval for devices, withdrawal of marketing approvals/clearances and criminal prosecution.

In the U.S., medical devices are classified into
one of three classes (Class I, II or III) on the basis of the controls deemed necessary by the FDA to reasonably assure their safety and effectiveness.



16

##### Table of Contents

Under FDA regulations, Class I devices, the least regulated category, are subject to general controls and Class II devices are subject to general and special
controls. Generally, Class III devices are those that must receive premarket approval by the FDA to ensure their safety and effectiveness.

Before we can
introduce a new device into the market, we must generally obtain market clearance through a 510(k) notification or premarket approval through a premarket approval (PMA) application. A 510(k) clearance will be granted if the submitted
information establishes that the proposed device is substantially equivalent to a legally marketed Class I or II medical device, or to a Class III medical device for which the FDA has not required a PMA. The FDA may determine that a
proposed device is not substantially equivalent to a legally marketed device, or that additional information or data are needed before a substantial equivalence determination can be made. A request for additional data may require that clinical
studies be performed to establish the devices substantial equivalence.

Commercial distribution of a device for which a 510(k)
notification is required can begin only after the FDA issues a letter finding the device to be substantially equivalent to a predicate device. Pursuant to the FFD&C Act, the FDA must make a determination with respect to a 510(k)
submission within 90 days of its receipt. The FDA may, and often does, extend this time frame by requesting additional data or information.

A not
substantially equivalent determination, or a request for additional information, could delay or prevent the market introduction of new products for which we file such notifications. For any of our products that are cleared through the 510(k)
process, modifications or enhancements that could significantly affect the safety or efficacy of the device or that constitute a major change to the intended use of the device will require new 510(k) submissions. The FDA has implemented a policy
under which certain device modifications may be submitted as a Special 510(k), which will require only a 30-day review. Special 510(k)s are limited to those device modifications that do not affect the intended use or alter the
fundamental scientific technology of the device and for which substantial equivalence can be demonstrated through design controls.

We must file a PMA if
our proposed device is not substantially equivalent to a legally marketed Class I or Class II device, or if it is a Class III preamendment device (on the market since prior to May 28, 1976) for which FDA has called for PMAs. A PMA must be
supported by valid scientific evidence that typically includes extensive data, including pre-clinical and clinical trial data, to demonstrate the safety and effectiveness of the device, as well as extensive manufacturing information.

FDA review of a PMA generally takes one to two years from the date the PMA is accepted for filing, but may take significantly longer. The review time is often
significantly extended should the FDA ask for more information or clarification of information already provided in the submission.

During the PMA review
period, an advisory committee, typically a panel of clinicians, will likely be convened to review and evaluate the application and provide recommendations to the FDA as to whether the device should be approved. The FDA is not bound by the
recommendations of the advisory panel. Toward the end of the PMA review process, the FDA generally will conduct an



17



---

##### Table of Contents

inspection of the manufacturers facilities to ensure that they are in compliance with Quality System Regulation (QSR) requirements.

If the FDAs evaluations of both the PMA and the manufacturing facilities are favorable, the FDA will either issue an approval letter or an
approvable letter, which usually contains a number of conditions that must be met in order to secure final approval of the PMA. When, and if, those conditions have been fulfilled to the satisfaction of the FDA, the agency will issue an
approval letter, authorizing commercial marketing of the device for certain indications. If the FDAs evaluation of the PMA or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue a not approvable
letter. The FDA may also determine that additional clinical trials are necessary, in which case PMA approval may be delayed up to several years while we conduct additional clinical trials and submit an amendment to the PMA. The PMA process can
be expensive, uncertain and lengthy, and a number of devices for which other companies have sought FDA approval have never been approved for marketing.

Modifications to a device that is the subject of an approved PMA (including modifications to its labeling, raw material components or manufacturing process) may require approval by the FDA in the form of a PMA supplement or new PMA.
Supplements to a PMA often require the submission of the same type of information required for an initial PMA, except that the supplement is generally limited to that information needed to support the proposed change from the product covered by the
original PMA.

If clinical trials of a device are required in connection with either a 510(k) notification or a PMA and the device presents a
significant risk, we will be required to file an IDE application prior to commencing clinical trials. The IDE application must be supported by data, typically including the results of animal and laboratory testing. If the IDE application
is reviewed and approved by the FDA and one or more appropriate Institutional Review Boards (IRBs), clinical trials may begin at a specific number of investigational sites with a specific number of patients, as approved by the FDA. If
the device presents a non-significant risk to the patient, we may begin the clinical trials after obtaining approval for the study by one or more appropriate IRBs. For significant risk devices, we must submit an IDE
supplement to the FDA and receive approval from the FDA before we, or our investigator, may make a change to the investigational plan that may affect its scientific soundness or the rights, safety or welfare of human subjects. IRB approval may be
required for changes in the investigational plan for both non-significant risk and significant risk devices.

Any products manufactured or distributed by
us pursuant to FDA clearances or approvals are subject to extensive regulation by the FDA, including reporting and record keeping requirements. Device manufacturers are required to register their establishments and list their devices with the FDA
and certain state agencies, and are subject to periodic inspections by the FDA and certain state agencies. The FFD&C Act requires devices to be manufactured in accordance with QSR requirements that impose certain procedural and documentation
requirements upon us with respect to manufacturing and quality assurance activities. Medical devices are also subject to post-market reporting requirements for deaths or serious injuries when the device may have caused or contributed to the death or
serious injury, and for certain device malfunctions that would be likely to cause or contribute to a death or serious injury if the malfunction were to recur. If safety or efficacy problems occur after the product reaches the



18

##### Table of Contents

market, the FDA may impose severe limitations on the use of any approved or cleared product.

Our labeling and promotion activities are subject to scrutiny by the FDA and, in certain instances, by the Federal Trade Commission. The FDA actively enforces regulations prohibiting marketing of products for
unapproved or uncleared uses. We, as well as our products, are also subject to a variety of state laws and regulations in those states or localities where our products are or will be marketed. Any applicable state or local regulations may hinder our
ability to market our products in those states or localities. We are also subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control
and disposal of hazardous or potentially hazardous substances. There can be no assurance that we will not be required to incur significant costs to comply with such laws and regulations now or in the future or that such laws or regulations will not
have a material adverse effect upon our ability to do business. Noncompliance with applicable requirements can result in, among other things, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of
production, failure of the government to grant the pre-market clearance or premarket approval for devices, withdrawal of marketing approvals, clearances and criminal prosecution.

Europe

In order to sell our products within the EU, we are required to achieve compliance with the requirements of the MDD
and affix a CE Mark on our products to attest such compliance. To achieve this, our products must meet the essential requirements defined under the MDD relating to safety and performance and we must successfully undergo a verification of
our regulatory compliance (conformity assessment) by an independent Notified Body. We have selected KEMA as our Notified Body. The nature of the conformity assessment will depend on the regulatory class of our products. Under
European law, our products, other than IMBIBE and ALIQUOT (which are Class I  sterile and Class II-A, respectively), are likely to be in Class III. In the case of Class III products, we must (as a result of the regulatory structure which we
have elected to follow) establish and maintain a complete quality system for design and manufacture as described in Annex II of the MDD and demonstrated by compliance with EN 13485:2003. We are certified as meeting the requirements of ISO 9001: 2000
and EN 13485 for the period July 1, 2006 through July 1, 2009. Our Notified Body has audited our quality system and determined that it meets the requirements of the MDD. In addition, the Notified Body must approve the specific design of
each device in Class III, IIa and IIb. As part of the design approval process, the Notified Body must also verify that the products comply with the essential requirements of the MDD. In order to comply with these requirements, we must, among other
things, complete a risk analysis and may be required to present clinical data. The clinical data presented by us must provide evidence that the products meet the performance specifications claimed by us, provide sufficient evidence of adequate
assessment of unwanted side effects and demonstrate that the benefits to the patient outweigh the risks associated with the device. We are subject to continued surveillance by the Notified Body and are required to report any serious adverse
incidents to the appropriate authorities. The decision of the Notified Body is valid for a maximum of five years but may be extended by application for additional five year periods. We also are required to comply with additional national
requirements that are outside of the scope of the MDD. There can be no assurance that we will not be required to incur significant costs to comply with such laws and regulations now or in the future or that such laws or regulations will not have a
material adverse

effect upon our ability to do business.

THIRD-PARTY
REIMBURSEMENT

Successful sales of our products in the U.S. and other markets will depend on the availability of adequate coverage and reimbursement
from third-party payers relative to our products. In the U.S., health care providers, such as hospitals and physicians that purchase or utilize our products for treatment of their patients, generally rely on independent third-party payers, such as
private insurance companies or HMOs, and governmental payers, such as Medicare and Medicaid, to reimburse all or part of the costs and fees associated with the provision of items and services using our products. Physicians, hospitals, and other
health care providers may not purchase our products if they do not receive satisfactory reimbursement from these payers for the cost of procedures using our products.

Each payer has its own process and standards for determining whether it will cover and reimburse a procedure or particular product. Private payers often rely on the lead of the governmental payers in rendering
coverage and reimbursement determinations. Therefore, achieving favorable Medicare coverage and reimbursement is usually a significant gating issue for successful introduction of a new product. Medicare is a federally funded program managed by the
Centers for Medicare and Medicaid Services, through local fiscal intermediaries and carriers, that administers coverage and reimbursement for certain health care items and services furnished to the elderly and disabled. Medicaid is an insurance
program for the poor that is both federally and state funded and managed by each state. The federal government sets general guidelines for Medicaid and each state creates specific regulations that govern their individual program.

Medicare provides, among other things, health care benefits that cover, within prescribed limits, the major costs of most medically necessary care for such individuals,
subject to certain deductibles and co-payments. The Medicare program has established, and continues to establish, standards and guidelines for the coverage and reimbursement of certain procedures, equipment, supplies and other items and services.
Generally, in order to be covered and reimbursed by Medicare, a health care item or service furnished to a Medicare beneficiary must be reasonable and necessary for the diagnosis or treatment of an illness or injury or to improve the functioning of
a malformed body part.

The methodology for determining (1) the coverage status of our products; and (2) the amount of Medicare reimbursement for
our products, varies based upon, among other factors, the setting in which a Medicare beneficiary received health care items and services. Acute care hospitals are generally reimbursed by Medicare for inpatient operating costs based upon
prospectively determined rates. Under the Prospective Payment System (PPS), acute care hospitals receive a predetermined payment rate based upon the Diagnosis-Related Group, or DRG, into which each Medicare beneficiary stay is assigned,
regardless of the actual cost of the services provided. Certain additional or outlier payments may be made to a hospital for cases involving unusually high costs. Accordingly, acute care hospitals generally do not receive direct Medicare
reimbursement under PPS for the distinct costs incurred in purchasing our products. Rather, reimbursement for these costs is deemed to be included within the DRG-based payments made to hospitals for the services furnished to Medicare-eligible
inpatients in which our products are utilized. Because PPS payments are based on predetermined rates and may be less than a



20



---

##### Table of Contents

hospitals actual costs in furnishing care, acute care hospitals have incentives to lower their inpatient operating costs by utilizing equipment,
devices and supplies, including those sold by us, that will reduce the length of inpatient stays, decrease labor or otherwise lower their costs. Our product revenue could be affected negatively if acute care hospitals discontinue product use due to
insufficient reimbursement, or if other treatment options are perceived to be more cost-effective. Medicare also reimburses most outpatient services based on a prospective or predetermined payment basis, subject to certain exceptions and
limitations. Similarly, some states reimburse certain health care providers for inpatient services under their Medicaid programs by using prospective rates for diagnosis-related groups of illnesses. Therefore, health care providers may refuse to use
our products if coverage or reimbursement is inadequate. Also, any changes in federal legislation, regulations and policy affecting Medicare coverage and reimbursement relative to our products could have a material effect on our results of
operations.

Inadequate coverage or reimbursement by private insurance companies and government programs could significantly reduce usage of our products.
In addition, an increasing emphasis on managed care in the U.S. has placed, and we believe will continue to place, greater pressure on medical device pricing. Such pressures could have a material adverse effect on our ability to sell our products
profitably. Failure by hospitals and other users of our products to obtain favorable coverage or reimbursement from third-party payers or changes in governmental and private third-party payers policies toward coverage or reimbursement for
procedures employing our products could reduce demand for our products.

Member countries of the EU operate various combinations of centrally financed
health care systems and private health insurance systems. The relative importance of government and private systems varies from country to country. The choice of devices is subject to constraints imposed by the availability of funds within the
purchasing institution and by hospital and authority priorities. Medical devices are most commonly sold to hospitals or health care facilities at a price set by negotiation between the buyer and the seller. A contract to purchase products may result
from an individual initiative or as a result of a competitive bidding process. In either case, the purchaser pays the supplier, and payment terms vary widely throughout the EU. Failure to obtain favorable negotiated prices with hospitals or health
care facilities could adversely affect sales of our products.

HEALTH CARE FRAUD AND ABUSE LAWS

To the extent our products receive government reimbursements, we are subject to various federal and state laws pertaining to health care fraud and abuse, including
anti-kickback laws and false claims laws. Violations of these laws are punishable by criminal, civil and/or administrative sanctions, including, in some instances, imprisonment and exclusion from participation in federal and state health care
programs, including Medicare, Medicaid and veterans health programs. Because of the far-reaching nature of these laws, there can be no assurance that the occurrence of one or more violations of these laws would not result in a material adverse
effect on our business, financial condition and results of operations.

Anti-Kickback Laws. To the extent that our products receive government
reimbursement, our operations are subject to federal and state anti-kickback laws. Certain provisions of the Social Security Act prohibit entities such as us from knowingly and willingly offering, paying, soliciting or receiving any form of
remuneration (including any kickbacks, bribe or rebate) in



21

##### Table of Contents

return for the referral of items or services for which payment may be made under a federal health care program, or in return for the recommendation,
arrangement, purchase, lease or order of items or services for which payment may be made under a federal health care program. Violation of the federal anti-kickback law is a felony, punishable by criminal fines and imprisonment for up to five years
or both. In addition, the Department of Health and Human Services may impose civil penalties and exclude violators from participation in federal health care programs such as Medicare and Medicaid. Many states have adopted similar prohibitions
against payments intended to induce referrals of products or services paid by Medicaid or other third party payors.

False Claims. The federal False
Claims Act imposes civil and criminal liability on individuals or entities who submit (or cause the submission of) false or fraudulent claims for payment to the government. Violations of the federal False Claims Act may result in penalties equal to
three times the damages which the government sustained, an assessment of between $5,000 and $10,000 per claim, civil monetary penalties and exclusion from participation in the Medicare and Medicaid programs.

The federal False Claims Act also allows a private individual to bring a qui tam suit on behalf of the government against an individual or entity for violations
of the False Claims Act. In a qui tam suit, the private plaintiff is responsible for initiating a lawsuit that may eventually lead to the government recovering money of which it was defrauded. After the private plaintiff has initiated the
lawsuit, the government must decide whether to intervene in the lawsuit and become the primary prosecutor. In the event the government declines to join the lawsuit, the private plaintiff may choose to pursue the case alone, in which case the private
plaintiffs counsel will have primary control over the prosecution (although the government must be kept apprised of the progress of the lawsuit). In return for bringing the suit on the governments behalf, the statute provides that the
private plaintiff is entitled to receive up to 30% of the recovered amount from the litigation proceeds if the litigation is successful plus reasonable expenses and attorneys fees. Recently, the number of qui tam suits brought against
entities in the health care industry has increased dramatically. In addition, a number of states have enacted laws modeled after the False Claims Act that allow those states to recover money which was fraudulently obtained from the state.

Other Fraud and Abuse Laws. The Health Insurance Portability and Accountability Act of 1996 created, in part, two new federal crimes: Health Care
Fraud and False Statements Relating to Health Care Matters. The Health Care Fraud statute prohibits the knowing and willful execution of a scheme or artifice to defraud any health care benefit program. A violation of the statute is a felony and may
result in fines and/or imprisonment. The False Statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact by any trick, scheme or device or making any materially false, fictitious or fraudulent
statement in connection with the delivery of or payment for health care benefits, items or services. A violation of this statute is a felony and may result in fines and/or imprisonment.

The countries of the EU have individual and varying legislative provisions governing health care fraud and abuse, including provisions governing inducement to purchase. Violation of these provisions can lead to action
both against the provider of the device and against the health care provider.

PRODUCT LIABILITY AND INSURANCE

##### Table of Contents

We manufacture medical devices used on patients in surgery, and we may be subject to product liability lawsuits. We have
experienced two product liability claims to date, which we have successfully resolved. There can be no assurance that other product liability claims will not be asserted against us in the future. Under certain of our agreements with our independent
distributors and hospital customers, we provide indemnification from product liability claims. Any product liability claim brought against us, with or without merit, could result in the increase of our product liability insurance rates or the
inability to secure coverage in the future. In addition, we would have to pay any amount awarded by a court in excess of policy limits. We maintain product liability insurance in the annual aggregate amount of up to $10,000,000, although our
insurance policies have various exclusions. Thus, we may be subject to a product liability claim for which we have no insurance coverage, in which case we may have to pay the entire amount of any award.

EMPLOYEES

As of December 31, 2007, we had 221 full-time
employees, with 112 employees at our Malvern, Pennsylvania headquarters, 101 employees throughout the U.S. and 8 employees in Europe. We consider our relations with our employees to be good.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

If our current products are not commercially
successful, or if we do not increase our product portfolio and successfully commercialize new products, our operating results will be impaired and our viability will be jeopardized.

We are highly dependent on successfully selling our products for which we have received regulatory approval or clearance. To date, we have regulatory clearance or approval to market VITOSS, IMBIBE, VITAGEL and
CELLPAKER in the United States. We have also received regulatory clearance or approval to market VITOSS, CORTOSS, ALIQUOT, VITAGEL and CELLPAKER for specified uses in the European Union and countries adhering to the regulatory standards of the
European Union, and in Australia for VITOSS, CORTOSS and ALIQUOT. Revenues generated from sales of our approved or cleared products in their approved territories have not been and in the future may not be sufficient to fund operations. There is no
assurance that we can increase our product portfolio or that any additional products will be commercially successful and generate revenues sufficient to enable us to fund operations. In particular, if our CORTOSS product is not cleared for marketing
in the United States or does not become commercially successful, our long-term viability may be jeopardized. In January 2008, we submitted to the FDA a 510(k) application for the use of CORTOSS in vertebral augmentation but cannot guarantee if or
when we will receive FDA clearance of CORTOSS. FDA clearance of CORTOSS would permit us to market and sell the material in the United States.

Certain
factors that may also limit our ability to increase sales include:



| |  |  | the ability of our direct sales representatives to develop and retain a customer base and compete effectively with larger sales forces offering more extensive
product portfolios;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our dependence in certain geographical areas on the efforts of independent agents and distributors over which we have limited control to promote the use of our
products;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | the introduction of new products based upon competing technologies into the market by competing orthopedic and other companies;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | our dependence on the continued publication of independent pre-clinical and clinical data to support the use of our products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | our need to educate and train a sufficient number of surgeons to create demand for our products; and
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | the need for payors to authorize insurance reimbursement for procedures using our products.
| | - |  | -------------------------------------------------------------------------------------------

Market acceptance of our products will largely depend on our ability to demonstrate their relative safety, efficacy, cost-effectiveness and ease of use. Surgeons will
not use our products unless they determine, based on experience, clinical data and recommendations from prominent surgeons and mentors that our products are safe and effective. Our products are based on newer technologies and compete with more
established treatments currently accepted as the standards of care. The attributes of some of our products may require some changes in surgical techniques that have become standard within the medical community, and there may be resistance to change.
Therefore, for these products, we must be able to convince surgeons who currently favor existing techniques to switch to new procedures that would use our products. Many surgeons will not purchase our products until there is sufficient, long-term
clinical evidence to convince them to alter their existing treatment methods. In addition, surgeons may be slow to change their medical treatment practices because of perceived liability risks arising from the use of new products and the uncertainty
of third party reimbursement for our products. Any failure to gain market acceptance of our products could result in lower sales and our inability to become profitable.

If our losses continue in the long term, they could limit our growth in the orthopedic industry and jeopardize our viability.

We have experienced negative operating cash flows since our inception and have funded our operations primarily from proceeds received from sales of our securities. In December 2005, we raised an aggregate of
approximately $12,900,000 in net proceeds from the sale of 4,318,182 shares of our common stock to institutional investors. In November and December 2006, we raised approximately $26,600,000 in net proceeds from the sale of 8,819,128 shares of our
Common Stock to institutional investors. In July 2007, we sold 12,317,066 shares of our common stock for net proceeds of approximately $32,200,000. In addition, in July 2007, we entered into a $45,000,000 senior secured note purchase facility with
LB I Group Inc., an affiliate of Lehman Brothers Inc., under which we have issued $25,000,000 of our 10% senior secured notes due July 30, 2012. We believe our existing cash, cash equivalents, and investments of $48,407,888 as of
December 31, 2007 will be sufficient to meet our currently estimated operating and investing requirements for the foreseeable future. To date, we have not been profitable. We have incurred substantial operating losses since our inception and at
December 31, 2007, had an accumulated deficit of $165,919,937. These losses have resulted principally from:



| |  |  | the development and patenting of our technologies;
| | - |  | --------------------------------------------------



| |  |  | pre-clinical and clinical studies;
| | - |  | ----------------------------------



| |  |  | preparation of submissions to the FDA and foreign regulatory bodies;
| | - |  | --------------------------------------------------------------------



| |  |  | the development of manufacturing, sales and marketing capabilities; and
| | - |  | -----------------------------------------------------------------------

##### Table of Contents

| |  |  | the repurchase of Royalty Trusts revenue interest.
| | - |  | ---------------------------------------------------

We expect to continue to incur significant operating losses in the future as we continue our product development efforts, expand our marketing and sales activities and further develop our manufacturing capabilities. We may not ever
successfully commercialize our products in development. We may never be able to achieve or maintain profitability in the future and our products may never be commercially accepted or generate sufficient product sales to fund operations.

The data from our pivotal CORTOSS trial may not be sufficient or sufficiently supportive, which may delay or preclude FDA clearance for commercial distribution of
this product.

The FDA granted approval to conduct our pivotal trial for CORTOSS in November 2003. In this trial we are studying CORTOSS for use in
vertebral augmentation. We began enrollment in 2004 and completed enrollment in the first quarter of 2007. In January 2008, we submitted a 510(k) application for the use of CORTOSS in vertebral augmentation. The protocol for the trial contemplates a
24-month follow up period for each patient, but the data included in our 510(k) submission does not include 24-month follow-up data for all enrolled patients. Accordingly, the FDA may require that we complete the 24-month follow-up period for all
enrolled patients and provide relevant data as part of our 510(k) submission. This requirement would delay any clearance of CORTOSS. In addition, the completion of our pivotal trial and submission package for CORTOSS may be delayed or terminated for
other reasons, including, but not limited to:



| |  |  | subjects are not followed-up at the rate we currently expect;
| | - |  | -------------------------------------------------------------



| |  |  | subjects experience an unacceptable rate or severity of adverse side effects;
| | - |  | -----------------------------------------------------------------------------



| |  |  | third party clinical investigators do not perform our pivotal trial on our anticipated schedule or consistent with the clinical trial protocol, Good Clinical
Practice and regulatory requirements, or other third party organizations do not perform data collection and analysis in a timely or accurate manner;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | inspections of our clinical trial sites by the FDA or Institutional Review Boards, or IRBs, find regulatory violations that require us to undertake corrective
action, suspend or terminate one or more sites, or prohibit us from using some or all of the data in support of our FDA submission;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in laws, governmental regulations, administrative actions, or the general regulatory climate affecting either all medical devices or those designed for the
spine industry, force us to modify the conduct of our trials or otherwise create unexpected burdens;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the interim results of our clinical trials are inconclusive or negative;
| | - |  | ------------------------------------------------------------------------



| |  |  | one or more of our IRBs suspends or terminates our trial at an investigational site or withdraws its approval of our trial;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | one or more of our clinical investigators withdraws from our trial or deviates from our approved protocol; or
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | third parties, investigators and service providers involved with our pivotal trial do not perform as contractually required or expected.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------

If one or more of the foregoing problems occur, it may delay or prevent us from obtaining clearance of the CORTOSS product.

If we are unable to operate an effective sales and distribution network, our ability to generate sales and become
profitable will be impaired.

We have assembled a field sales network of direct sales representatives and independent non-stocking distributors in the
U.S. to market VITOSS, VITAGEL, CELLPAKER and IMBIBE. Outside of the U.S., we utilize a network of independent stocking distributors to market VITOSS, CORTOSS, ALIQUOT, VITAGEL and CELLPAKER. We seek to strengthen our field sales network through the
addition of direct sales representatives in those U.S. territories where either we do not have independent distributor coverage or the territories are underserved. We are dependent upon our direct sales representatives and distributors for the sale
of our products. Any failure to maintain and effectively manage our distribution network will impair our ability to generate additional sales and become profitable.

In an effort to further grow our sales, we continue to build our sales management team and add direct sales representatives to our organization for certain open or underserved territories in the U.S. The addition of
direct sales representatives will increase our operating expenses. Furthermore, there is no assurance that adding direct sales representatives will improve sales or that our direct sales representatives will be successful in generating sufficient
sales to cover the cost of supporting their sales activities. There is no assurance that we will be able to attract and retain qualified personnel to market or sell our products or that we will successfully manage this type of sales and distribution
method.

There can be no assurance that our distributors will perform effectively their obligations in their respective territories as expected, or that we
will continue to derive any revenue from these arrangements. We cannot assure that our interests will continue to coincide with those of our distributors. In addition, we cannot assure that our distributors will not develop independently, or with
other companies, competitive products.

The independent U.S. distributors selling VITOSS generally sell products for other orthopedic companies. A single
distributor may sell VITOSS, as well as hardware manufactured by other orthopedic companies consisting of metal plates, screws and titanium spinal cages, to end user hospitals. Our sales could be adversely affected if, for any reason, one or more of
our successful distributors lost their hardware product line provided by other orthopedic companies since VITOSS is typically sold with such hardware products. Additionally, our independent distributors may be unwilling to carry or unable to
effectively sell VITOSS as a result of the introduction of new products based upon other technologies that could compete with VITOSS. Our sales could be adversely affected if one or more of our successful distributors eliminated VITOSS from its
product line for any other reason or terminated its arrangement with us. Our sales could also be adversely affected if our independent distributors become concerned that their arrangements with us could be eliminated as a result of another
companys offer or threat to acquire us. The complete product line represented by the distributors, including our products, is an important factor in the distributors ability to penetrate the markets for our products. Accordingly, our
ability to penetrate the markets that we serve or intend to serve is highly dependent upon the quality and breadth of the other product lines carried by our distribution network, the components of which may change from time to time, and over which
we have little or no control.

If we do not manage commercial scale manufacturing capability and capacity for our products in compliance with
regulatory requirements and in a cost-effective manner, our product sales and operating results may suffer.

The manufacture of our products is subject
to regulation and periodic inspection by various regulatory bodies for compliance with the FDA Quality System Regulation (the QSR), and EU Medical Device Directives requirements, International Organization for Standardization
(ISO) 9000 Series standards, ISO/European Norm (EN) 13485 and equivalent requirements.

Our 24,800-square foot VITOSS, VITAGEL and
CORTOSS FDA-registered manufacturing facilities located in Malvern, Pennsylvania produce our commercial products, are leased through July 2012 and are certified as meeting the requirements of ISO 9000: 2000 and EN 13485 for the period July 1,
2006 through July 1, 2009. We are currently required to demonstrate and maintain compliance with the QSR, which is complex regulatory scheme that covers the methods and documentation of the design, testing, control, manufacturing, labeling,
quality assurance, packaging, storage and shipping of our products. The FDA enforces the QSR through periodic unannounced inspections. We have been, and anticipate in the future being, subject to such inspections. We assumed full responsibility for
manufacturing VITAGEL in 2006 and CELLPAKER in 2007 after receiving the requisite approvals from the FDA. There can be no assurance that we will be able to comply with FDA requirements to continue to manufacture VITOSS, VITAGEL, CORTOSS or
CELLPAKER, which could result in delay or inability to manufacture and sell the products. We believe our manufacturing facilities have the capacity to meet our commercial needs at least through the first half of 2010 and plan to expand our
manufacturing capacity in 2008 and 2009 to meet our commercial needs for the next several years.

Our third-party manufacturers are also regulated by
governmental agencies and are required to be ISO 9001/EN 13485-certified or otherwise meet our quality system requirements. We manufacture CELLPAKER, IMBIBE and ALIQUOT through outside third-party contract manufacturers. Our VITOSS is converted to
VITOSS FOAM by Kensey, our development partner.

Our product sales depend upon, among other things, our ability to manufacture our products in commercial
quantities, in compliance with regulatory requirements and in a cost-effective manner. There can be no assurance that regulatory authorities will not, during the course of an inspection of existing or new facilities, identify what they consider to
be deficiencies in meeting the applicable quality standards and request or seek remedial action.

Failure to comply with such regulations or a delay in attaining compliance may result in:



| |  |  | warning letters;
| | - |  | ----------------



| |  |  | injunctions suspending the manufacture of products;
| | - |  | ---------------------------------------------------



| |  |  | civil and criminal penalties;
| | - |  | -----------------------------



| |  |  | refusal to grant premarket approvals or clearances, CE Certifications, CE Certification renewals, or clearances to products that are subject to future or pending
submissions;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | product recalls or seizures of products;
| | - |  | ----------------------------------------



| |  |  | total or partial suspensions of production; and
| | - |  | -----------------------------------------------



| |  |  | refusal to permit the import or export of our products.
| | - |  | -------------------------------------------------------

The imposition of any of these sanctions could cause our business and operating results to suffer. Furthermore, if we or any of our third party manufacturers cannot produce our products, our product sales would suffer.

We are dependent on a limited number of specialty suppliers of certain raw materials, and our business and financial results could be harmed if a specialty supplier
no longer provides materials to us.

Our ability to manufacture VITOSS, VITAGEL and CORTOSS and to have VITOSS FOAM and Bioactive VITOSS FOAM
manufactured by and for us is dependent on a limited number of specialty suppliers of certain raw materials. We have a single source supplier for thrombin, a requisite raw material in our VITAGEL product. The failure of a supplier to continue to
provide us with these materials at a price or quality acceptable to us, or at all, would have a material adverse effect on our ability to manufacture these products. Although we believe that we maintain good relationships with our suppliers, we
cannot assure that such supplies and services will continue to be available with respect to our current and future commercialized products.

Allergan, our
supplier of collagen for VITAGEL notified us in 2007 of its intent to shut down its collagen-processing facility and cease supplying us with this collagen raw material under our supply agreement. In November 2007, we entered into a supply and
license agreement under which Allergan agreed to sell us additional lots of collagen in 2008 before its facility closes. We expect delivery of this strategic collagen reserve supply by October 31, 2008. These quantities are in addition to
collagen supplied by Allergan to us in the fourth quarter of 2007 under our prior supply arrangement. We believe the strategic collagen reserve for VITAGEL to be acquired under the supply and license agreement, together with the collagen supplied to
us during the fourth quarter of 2007, will be sufficient to meet our needs for VITAGEL through at least the first half of 2010. We commenced renovations in the first quarter of 2008 at sites we currently lease to establish a facility to process
collagen that we plan to obtain after exhausting the strategic collagen reserve expected from Allergan. We are also exploring suppliers of



28

##### Table of Contents

collagen for our planned processing facility. The occurrence of any of the following could have a material adverse effect on our ability to manufacture and
sell VITAGEL and CELLPAKER, which is approved for use only in conjunction with VITAGEL:



| |  |  | our inability to obtain a strategic reserve of collagen sufficient to meet our anticipated sales requirements, including Allergans inability to successfully
and timely manufacture the strategic collagen reserve supply;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our inability to establish our collagen processing facility in a timely manner before our strategic reserve is exhausted, if at all;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | delays caused by the need to secure PMA approval of the new processing facility for the collagen raw material;
| | - |  | --------------------------------------------------------------------------------------------------------------



| |  |  | our inability to find an adequate supplier of collagen for any processing facility; or
| | - |  | --------------------------------------------------------------------------------------



| |  |  | our inability to find an alternative supplier with acceptable prices, quality and requisite regulatory approvals.
| | - |  | -----------------------------------------------------------------------------------------------------------------

If we are unable to sell VITAGEL and CELLPAKER for a period of time, our customers may seek alternative products and we may lose market share for VITAGEL and CELLPAKER.
Further, there is no assurance that we will regain any VITAGEL and CELLPAKER market share that may be lost.

Moreover, a delay or inability to sell VITAGEL
and CELLPAKER could result in an impairment charge to our intangible asset represented by the then-remaining balance of our original $9,000,000 prepayment of the profit-sharing license royalties on sales of VITAGEL and CELLPAKER. We prepaid the
royalties on December 29, 2006 and the term of our license for these products is scheduled to expire July 31, 2017.

We also cannot assure that
supply or manufacturing capability will be sufficient to meet our own needs and Angiotechs needs if Angiotech elects to be supplied by us under our license agreement with them. Under our license agreement with Angiotech, in the future we may
be obligated, under certain circumstances, to provide COSTASIS (an Angiotech-branded VITAGEL product) and certain COSTASIS materials to Angiotech. Our collagen supply or manufacturing capabilities may be inadequate, and we may need to seek
additional suppliers for COSTASIS materials.

Our plan to acquire a strategic collagen reserve and manufacture additional VITAGEL inventory until we can
successful obtain collagen and process it ourselves may also result in excess inventory. If we cannot successfully sell the VITAGEL inventory, we may be required to write off any expired inventory that remains unsold.

We are dependent on a limited number of specialized manufacturing suppliers for certain products, and our business and financial results could be harmed if a third
party manufacturer fails to supply us with these products.

We are dependent upon Kensey and other third party manufacturers for the supply of certain
products. Approximately 61% of our product sales during the year ended December 31, 2007 was from products based upon our VITOSS FOAM platform co-developed with Kensey. Our

VITOSS is converted to VITOSS FOAM and Bioactive VITOSS FOAM by Kensey, our development partner. We also manufacture certain delivery accessory products
through third party specialty suppliers. There is no assurance that these manufacturers will continue to supply our requirements. If they fail to do so, we cannot guarantee that we will be able to engage another supplier for these products on a
timely basis and on acceptable terms. A delay in our ability to obtain adequate supplies of these products may negatively impact our product sales.

If
we fail to obtain and maintain the regulatory approvals or clearances necessary to make or sell our products, sales could be delayed or never realized.

The jurisdictions in which we seek to market our products will regulate these products as medical devices. In most circumstances, we and our distributors and agents must obtain regulatory clearances, approvals and certifications and
otherwise comply with extensive regulations regarding safety, quality and efficacy standards. These regulations vary from country to country, and the regulatory review can be lengthy, expensive and uncertain. We may not obtain or maintain the
regulatory clearances, approvals and certifications necessary to make or market our products in our targeted markets. Moreover, regulatory clearances, approvals and certifications that are obtained may involve significant restrictions on the
anatomic sites and types of procedures for which our products can be used. In addition, we may be required to incur significant costs in obtaining or maintaining our regulatory clearances, approvals and certifications. If we do not obtain or
maintain regulatory clearances, approvals and certifications to enable us to make or market our products in the U.S. or elsewhere, or if the clearances, approvals and certifications are subject to significant restrictions, we may never generate
significant revenues. The regulatory requirements in some of the jurisdictions where we currently market or intend to market our products are summarized below.

United States

Regulation by FDA.The FDA regulates the clinical testing, manufacturing, labeling, distribution and promotion of
medical devices. To date, we have received 510(k) clearance from the FDA to market our VITOSS, VITOSS FOAM, Bioactive VITOSS FOAM and IMBIBE labels, and are seeking 510(k) clearance for our ALIQUOT delivery system. During 2002 and 2003, we received
approval from the FDA to conduct two pilot clinical studies in the U.S. to study the use of CORTOSS in vertebral augmentation. We completed these two pilot clinical studies in 2007. During 2004, we commenced enrollment for a pivotal clinical study
in the U.S. approved by the FDA to further study the use of CORTOSS in vertebral augmentation using the vertebroplasty surgical technique. We completed patient enrollment of the pivotal clinical study in February 2007. There can be no assurance that
the data from these clinical trials will support FDA clearance to market this product for the designated use.

We are currently manufacturing VITOSS,
VITAGEL, CELLPAKER and CORTOSS in the U.S., distributing VITOSS, VITAGEL and IMBIBE in the U.S., and distributing VITOSS, CORTOSS, ALIQUOT, VITAGEL and CELLPAKER outside the U.S. We are manufacturing IMBIBE and ALIQUOT in the U.S. through outside
third-party contract manufacturers. In addition, under our agreement with Kensey, Kensey has the exclusive right to manufacture any approved or cleared jointly developed products under the agreement. This right extends until February 2014 for the
VITOSS FOAM product platform and at least until 2024 for the Bioactive VITOSS FOAM product platform.



30



---

##### Table of Contents

VITOSS and VITAGEL, as well as any other products that we manufacture or distribute following their approval or clearance
by the FDA, will be subject to extensive regulation by the FDA. If safety or efficacy problems occur after the product reaches the market, the FDA may impose severe limitations on the use of the product. Moreover, modifications to the approved or
cleared product may require the submission of a new 510(k) notification or premarket approval application or premarket application supplement. We may not be successful in obtaining approval to market the modified product in a timely manner, if at
all. Noncompliance with applicable requirements can result in, among other things, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the government to grant premarket clearance
or premarket approval for devices, withdrawal of marketing approvals and criminal prosecution.

Medical devices may be marketed only for the indications
for which they are approved or cleared. The FDA may not approve or clear indications that are necessary or desirable for successful commercialization. Indeed, the FDA may refuse our requests for 510(k) clearance or premarket approval of new
products, new intended uses or modifications to existing products. Our clearances can be revoked if safety or effectiveness problems develop.

European
Union and Other International Markets

General.International sales of medical devices are subject to the regulatory requirements of each country
in which the products are sold. Accordingly, the introduction of our products in markets outside the United States will be subject to regulatory approvals or clearances in those jurisdictions. The regulatory review process varies from country to
country. Many countries also impose product standards, packaging and labeling requirements and import restrictions on medical devices. In addition, each country has its own tariff regulations, duties and tax requirements. The approval or clearance
by foreign government authorities is uncertain and can be expensive. Our ability to market our products could be substantially limited due to delays in receipt of, or failure to receive, the necessary approvals or clearances.

Requirement of CE Certification in the European Union.To market a product in the European Union, we must be entitled to affix a CE mark, an international symbol
of adherence to quality assurance standards and compliance with applicable European medical device directives. A CE Certification enables us to market a product in all of the countries of the European Union, as well as in other countries, such as
Switzerland and Israel, that have mutual recognition agreements with the EU or have adopted the European Unions regulatory standards. To date, we have received a CE Certification for the use of VITOSS as a bone void filler, for the use of
CORTOSS in screw augmentation and vertebral augmentation procedures, for VITAGEL as a surgical hemostat and for certain delivery accessories for VITOSS, CORTOSS and VITAGEL. There can be no assurance that we will receive CE Certifications for
CORTOSS for any other indications for use or that we will receive CE Certifications for other products.

After clearance or approval of our products, we
are subject to continuing regulation by the FDA, and if we fail to comply with FDA regulations, our business could suffer.

Even after clearance or
approval of a product, we are subject to continuing regulation by the FDA, including the requirements that our facility be registered and our devices listed with the



31

##### Table of Contents

agency. We are subject to Medical Device Reporting regulations, which require us to report to the FDA if our products may have caused or contributed to a
death or serious injury or malfunction in a way that would likely cause or contribute to a death or serious injury if the malfunction were to recur. We must report corrections and removals to the FDA where the correction or removal was initiated to
reduce a risk to health posed by the device or to remedy a violation of the Federal Food, Drug, and Cosmetic Act caused by the device that may present a risk to health, and maintain records of other corrections or removals. The FDA closely regulates
promotion and advertising.

The FDA and state authorities have broad enforcement powers. Our failure to comply with applicable regulatory requirements
could result in enforcement action by the FDA or state agencies, which may include any of the following sanctions:



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



| |  |  | repair, replacement, refunds, recall or seizure of our products;
| | - |  | ----------------------------------------------------------------



| |  |  | operating restrictions or partial suspension or total shutdown of production;
| | - |  | -----------------------------------------------------------------------------



| |  |  | refusing or delaying our requests for 510(k) clearance or premarket approval of new products or new intended uses;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | withdrawing 510(k) clearance or premarket approvals that have already been granted; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | criminal prosecution.
| | - |  | ---------------------

If any of these events were
to occur, they could harm our business.

We have modified some of our products without FDA clearance. The FDA could retroactively determine that the
modifications were improper and require us to stop marketing and recall the modified products until such clearance is obtained.

Any modification to an
FDA-cleared device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new 510(k) clearance; any change that affects the safety or effectiveness of a PMA approved
device requires a premarket approval supplement. We have made modifications to some of our products in the past, and may make additional modifications in the future that we believe, based upon FDAs regulations and guidance, do not or will not
require additional clearances or approvals. If the FDA disagrees, we could be required to obtain new clearances or approvals for the modifications. We also may be required to recall and to stop marketing modified products until such clearance or
approval is obtained, which could harm our operating results. We may be required to submit extensive pre-clinical and clinical data to support these supplementary submissions, depending on the nature of the changes. We may not be able to obtain
additional 510(k) clearances or premarket approvals for modifications to, or additional indications for, our existing products in a timely fashion, or at all. Delays in obtaining future clearances or approvals would adversely affect our ability to
introduce new or enhanced products in a timely manner, which in turn would harm our operating results.

Our business will be damaged if we are unable to
protect our proprietary rights to our products, and we may be subject to intellectual property infringement claims by others.

We rely on patent
protection, as well as a combination of copyright, trade secret and trademark laws, nondisclosure and confidentiality agreements and other contractual restrictions to protect



32



---

##### Table of Contents

our proprietary technology. However, these measures afford only limited protection and may not adequately protect our rights. For example, our patents may be
challenged, invalidated or circumvented by third parties. As of March 7, 2008, we own or control twenty issued U.S. patents and sixteen pending patent applications in the U.S., and counterparts of certain of these patents and pending patent
applications worldwide, including Canada, Europe, Mexico and Japan. There can be no assurance that patents will issue from any of the pending patent applications. Moreover, we cannot be certain that we were the first creator of inventions covered by
pending patent applications or we were the first to file patent applications for the relevant inventions for the following reasons:



| |  |  | patent applications filed prior to December 2000 in the U.S. are maintained in secrecy until issued;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | patent applications filed after November 2000 in the U.S. are maintained in secrecy until eighteen months from the date of filing; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the publication of discoveries in the scientific or patent literature tends to lag behind actual discoveries.
| | - |  | -------------------------------------------------------------------------------------------------------------

If we do receive a patent, it may not be broad enough to protect our proprietary position in the technology or to be commercially useful to us. In addition, if we lose
certain key personnel, we may not be able to prevent the unauthorized disclosure or use of our technical knowledge or other trade secrets by those former employees. Furthermore, the laws of foreign countries may not protect our intellectual property
rights to the same extent as the laws of the U.S. Even if our intellectual property rights are adequately protected, litigation or other proceedings may be necessary to enforce our intellectual property rights, which could result in substantial
costs to us and divert management attention. If our intellectual property is not adequately protected, our competitors could use the intellectual property that we have developed to enhance their products and compete more directly with us, which
could damage our business.

In addition to the risk of failing to adequately protect our proprietary rights, there is a risk that we may become subject to
a claim that we infringe upon the proprietary rights of others. Although we do not believe that we are infringing the rights of others, third parties may claim that we are doing so. For additional information regarding a claim recently made against
us, see Item 3. Legal Proceedings, below. There is a substantial amount of litigation over patent and other intellectual property rights in the medical device industry generally, and in the spinal market segments particularly. If the holder of
a proprietary right brought an infringement action against us, the cost of litigating the claim could be substantial and divert management attention. In addition, if a court determined that one of our products infringed a proprietary right, we could
be prevented from selling that product unless we could obtain a license from the owner of the right. A license may not be available on terms acceptable to us, if at all. Modification of our products or development of new products to avoid
infringement may require us to conduct additional clinical trials for these modified or new products and to revise our filings with the FDA, which is time consuming and expensive. If we are not successful in obtaining a license or redesigning our
product, our business could suffer.

We have obtained certain of our intellectual property rights and our rights to develop and commercialize certain
products, and made certain commitments regarding our intellectual property and these rights, through license and development agreements with third parties. These



33

##### Table of Contents

agreements generally may be terminated by our counterparty if we materially breach any of our obligations under the agreement. We may disagree with these
third parties as to our and their obligations under the agreements or the interpretation of provisions in the agreements. Any such disagreements could cause these third parties to seek to terminate our rights under the particular agreement. If any
of our agreements were terminated, we could lose the rights to the product, product candidate or intellectual property covered by the agreement, reducing our revenue, potential revenues and significantly harming our business. Whether or not such a
termination were proper, if a dispute arises under any of our agreements, the need to resolve the dispute could consume significant resources and divert managements time and attention.

If we cannot keep up with technological changes and marketing initiatives of competitors, sales of our products may be harmed.

Extensive research efforts and rapid technological change characterize the market for products in the orthopedic and biomaterials markets. We anticipate that we will
face intense competition from medical device, medical products and pharmaceutical companies. For instance, the use of bone morphogenic proteins, or BMPs, in orthopedic surgery has increased significantly in the past five years. In addition, several
PMMA bone cements have received 510(k) clearance since 2004 for vertebral augmentation of VCFs. The spinal bone grafting market also saw the introduction of lumbar total disk replacement (TDR) devices in 2004 and cervical TDR devices in 2007 as
treatment alternatives for degenerative disc disease designed to preserve the motion of the vertebrae of the spine. Further, recombinant human thrombin was approved by the FDA in 2008 and may be positioned as a better alternative to bovine-derived
collagen, a raw material in our VITAGEL product. Our products could be rendered uncompetitive or obsolete by these and other competitors new technologies. We may be unable to respond to technological advances by others through the development
and introduction of new products or the modification of existing products. Moreover, many of our existing and potential competitors have substantially greater financial, marketing, sales, distribution, manufacturing and technological resources than
us. These competitors may be in the process of seeking FDA or other regulatory approvals or clearances, or patent protection, for competitive products. Our competitors could, therefore, commercialize competing products in advance of our products.
They may also enjoy substantial advantages over us in terms of:



| |  |  | research and development expertise;
| | - |  | -----------------------------------



| |  |  | experience in conducting clinical trials;
| | - |  | -----------------------------------------



| |  |  | experience in regulatory matters;
| | - |  | ---------------------------------



| |  |  | manufacturing efficiency;
| | - |  | -------------------------



| |  |  | name recognition;

| |  |  | established distribution channels; and
| | - |  | --------------------------------------



| |  |  | established relationships with health care providers and payors.
| | - |  | ----------------------------------------------------------------

These advantages may adversely affect our plans for market acceptance of our products.

If we default under our senior secured note purchase facility, we may be required to repay amounts due under the
facility, and we may incur additional interest and prepayment penalties. If we are unable to repay amounts due under the note facility, the note holders could foreclose on certain assets that are essential to our operations.

On July 30, 2007, we entered into a $45,000,000 senior secured note purchase facility with LB I Group Inc., an affiliate of Lehman Brothers Inc. Notes issued under
the facility are due July 30, 2012. We initially issued $25,000,000 principal amount of our 10% senior secured notes under the facility and used most of the proceeds to repurchase a revenue interest obligation.

Borrowings under the facility are guaranteed by us and one of our wholly-owned subsidiaries. The facility is secured by a first priority lien on substantially all of our
assets (including intellectual property) other than those exclusively related to CORTOSS and ALIQUOT. We are required to make quarterly interest only payments to the note holder. Outstanding principal amounts under the notes bear annual interest at
10%, provided that interest would accrue at 12% per year during the continuance of any event of default and would be payable on demand. Based on the amount outstanding under the facility as of December 31, 2007, we will incur quarterly
interest expense of $625,000 during 2008. The unpaid principal amount under the notes and accrued interest and all other obligations would become due and payable immediately if we are insolvent, are in bankruptcy proceedings or have a custodian or
receiver appointed for any substantial part of our property. If an event of default not described in the preceding sentence occurs and is continuing (including a change of control of the Company), then the holders of at least two-thirds in principal
amount of notes then outstanding may declare the unpaid principal amount of the notes, accrued interest and all other obligations due and payable immediately. In addition, if the notes become due and payable, whether automatically or by declaration,
by reason of any of the following events of default, then we must pay a prepayment premium of up to 16% of the outstanding principal balance of the notes then outstanding, depending on the timing of the prepayment:



| |  |  | We fail to pay any principal on any note or prepayment premiums, if any, when due and payable;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | We fail to pay any interest on any note or other amount (other than principal or prepayment premiums) for more than three business days after becoming due and
payable;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We are insolvent, in bankruptcy proceedings or have a custodian or receiver appointed for any substantial part of our property; or
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | A change of control of our company occurs.
| | - |  | ------------------------------------------

Under
the facility, we must comply with various financial and non-financial covenants. For example, we are required to maintain a minimum cash balance equal to at least 25% of the then outstanding principal amount under the notes in a separate account
that is pledged as collateral for the loan. As of December 31, 2007, we must maintain a minimum cash balance of $6,250,000. The primary non-financial covenants limit our ability to incur indebtedness or liens, sell assets, conduct mergers or
acquisitions, make investments and pay dividends.

As of December 31, 2007, we had $25,000,000 outstanding under the facility, had accrued
approximately $625,000 in interest thereon, and were in compliance with all covenants under the



35

##### Table of Contents

facility. Based on our current operating plans, we expect to be in compliance with the covenants under the facility within the next twelve months. However,
if we default under the facility and cannot repay amounts then due, the note holders could foreclose on the pledged assets, we could be forced into bankruptcy and we could be otherwise harmed.

We may seek to obtain additional funds through additional borrowings under our senior secured note purchase facility, other debt financings, or strategic alliances
with third parties either alone or in combination with equity or debt financing investments, which could adversely affect our financial condition and cause dilution to our existing shareholders.

There are factors that may cause our future capital requirements to be greater than anticipated or could accelerate our need for funds including, without limitation:



| |  |  | unforeseen developments during our pre-clinical and clinical trials;
| | - |  | --------------------------------------------------------------------



| |  |  | delays in the timing of receipt of required regulatory approvals or clearances to make or sell products;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | unforeseen difficulties in operating an effective direct sales and distribution network;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | unanticipated expenditures in research and product development or manufacturing activities;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | delayed, insufficient or lack of market acceptance of our products;
| | - |  | -------------------------------------------------------------------



| |  |  | unanticipated expenditures in the acquisition, enforcement and defense of intellectual property rights;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | unforeseen changes in healthcare reimbursement for procedures using our products;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | inability to increase sales of our approved or cleared products;
| | - |  | ----------------------------------------------------------------



| |  |  | inability to train a sufficient number of surgeons to create demand for our products;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | lack of financial resources to adequately support our operations;
| | - |  | -----------------------------------------------------------------



| |  |  | difficulties in maintaining commercial scale manufacturing capacity and capability;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | unforeseen problems with our third-party manufacturers and service providers or with our specialty suppliers of certain raw materials;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unanticipated difficulties in operating in international markets;
| | - |  | -----------------------------------------------------------------



| |  |  | the need to respond to technological changes and increased competition;
| | - |  | -----------------------------------------------------------------------



| |  |  | unforeseen problems in attracting and retaining qualified personnel to market our products;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | enactment of new legislation or administrative regulation or changes in the regulatory climate affecting our products or the markets in which we compete;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the application to our business of new court decisions and regulatory interpretations;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | claims that might be brought in excess of our insurance coverage;
| | - |  | -----------------------------------------------------------------



| |  |  | any imposition of penalties for failure to comply with regulatory guidelines; or
| | - |  | --------------------------------------------------------------------------------



| |  |  | managements perception that uncertainties relating to these factors may be increasing.
| | - |  | ---------------------------------------------------------------------------------------

In addition, we may seek to expand our operations and product line through acquisitions or joint ventures. Any such acquisitions or joint ventures may increase our
capital requirements.

Under our senior secured note purchase facility, we have the option through January 30, 2010 to issue up to an additional
$20,000,000 aggregate principal amount of 10% senior secured notes due July 30, 2012 to fund working capital and other general business purposes, including product acquisitions, sales force expansion and product development, if certain
conditions are met. In connection with entering into the facility, we issued to the note purchaser five-year warrants to



36



---

##### Table of Contents

purchase 1,466,276 shares of our common stock at an exercise price of $3.41 per share, of which warrants to purchase 733,138 shares are currently
exercisable. The unexercisable warrants become exercisable ratably upon future issuances of the 10% senior secured notes under the facility. If we borrow additional funds under our senior secured note purchase facility, our debt service obligation
would increase and some or all of the currently unexercisable warrants would vest.

If health care providers cannot obtain third-party reimbursement for
procedures using our products, or if such reimbursement is inadequate, we may never become profitable.

Successful sales of our products in the United
States and other markets will depend on the availability of adequate reimbursement from third-party payors. Healthcare providers, such as hospitals and surgery centers that purchase medical devices for treatment of their patients, generally rely on
third-party payors to reimburse all or part of the costs and fees associated with the procedures performed with these devices. Both public and private insurance reimbursement plans are central to product acceptance and use as healthcare providers
may refuse to use our products if reimbursement is inadequate. Inadequate reimbursement by private insurance companies and government programs could significantly reduce usage of our products.

In addition, an increasing emphasis on managed care in the United States has placed, and we believe will continue to place, greater pressure on medical device pricing.
Such pressures could have a material adverse effect on our ability to sell our products or to operate profitably.

If we do not successfully train a
sufficient number of surgeons, demand for our products could be adversely affected.

It is critical to the commercial success of our products that our
independent distributors and direct sales representatives succeed in training a sufficient number of surgeons and in providing them adequate instruction in the use of our products. This training requires a commitment of time and money by surgeons
that they may be unwilling to give. Even if surgeons are willing, if they are not properly trained, they may misuse or ineffectively use our products. This may result in unsatisfactory patient outcomes, patient injury, negative publicity or lawsuits
against us, any of which could damage our business and reduce product sales.

We may incur significant liability if it is determined that we are
promoting the off-label use of our medical devices. The unapproved or off-label use of our products could also adversely affect the reputation of our products.

Under the Federal Food, Drug, and Cosmetic Act and other laws, we are prohibited from labeling, training, or promoting our products for off-label uses. This prohibition
means that we cannot proactively discuss or provide information or training on the use of our products outside of their cleared or approved uses, except in certain limited scientific and other settings. In the practice of medicine, physicians may
use devices for off-label uses. Because the interpretation of these requirements is subjective, the FDA could deem some of our activities as promotional even when we believe in good faith that such activities were not promotional. A company that is
found to have improperly promoted off-label uses may be subject to significant liability, including civil and administrative remedies as well as criminal sanctions. Enforcement measures taken against us could harm our business.

##### Table of Contents

The medical devices that we manufacture and market, or intend to market, are subject to extensive regulation by the FDA,
the European Union Medical Device Directive and other worldwide regulatory agencies. In order to market our products, we must apply for, receive and maintain all necessary regulatory approvals or clearances in each applicable jurisdiction for
specified uses of the products. Under FDA regulations and laws of other countries, we are only permitted to commercially distribute our products for approved indication(s) or use(s); failure to comply with these regulations may subject us to FDA and
other enforcement action.

CORTOSS received CE Certification, an international symbol of adherence to quality assurance standards and compliance with
applicable European medical device directives, in January 2003 for use in repairing vertebral compression fractures and in October 2001 for use in screw augmentation procedures. However, surgeons may have attempted to use CORTOSS
off-label in procedures to repair vertebral compression fractures performed prior to the European Unions approval of CORTOSS for this type of procedure. Furthermore, not all surgeons have been trained in the proper use of CORTOSS
to repair vertebral compression fractures. A surgeon who has not been properly trained to use CORTOSS in a procedure to repair vertebral compression fractures could pose a risk to the reputation of our CORTOSS product. In addition, the occurrence of
an adverse event while using our product off-label in procedures other than the repair of vertebral compression fractures or screw augmentation could adversely affect the reputation of CORTOSS or any of our other products as well as us
and could subject us to liability.

We could be negatively impacted by future interpretation or implementation of federal and state fraud and abuse
laws, including anti-kickback laws and false claims laws.

To the extent that our products receive government reimbursement, we are subject to various
federal and state laws pertaining to health care fraud and abuse, including anti-kickback laws and false claims laws. Violations of these laws are punishable by criminal and/or civil sanctions, including, in some instances, imprisonment and
exclusion from participation in federal and state health care programs, including Medicare, Medicaid, and veterans health programs. We have not been challenged by a governmental authority under any of these laws and believe that our operations
are in compliance with these laws.

Health care fraud and abuse regulations are complex, and even minor, inadvertent irregularities can potentially give
rise to claims that the law has been violated. Any violations of these laws could result in a material adverse effect on our business, financial condition and results of operations. If there is a change in law, regulation or administrative or
judicial interpretations, we may have to change our business practices or our existing business practices could be challenged as unlawful, which could have a material adverse effect on our business, financial condition and results of operations.

We could become subject to false claims litigation under federal or state statutes, which can lead to civil money penalties, criminal fines and
imprisonment, and/or exclusion from participation in federal health care programs. These false claims statutes include the federal False Claims Act, which allows any person to bring suit alleging the false or fraudulent submission of claims for
payment under federal programs or other violations of the statute and to share in any amounts paid by the entity to the government in fines or settlement. Such suits, known as qui tam actions,



38



---

##### Table of Contents

have increased significantly in recent years and have increased the risk that companies like us may have to defend a false claim action. We could also become
subject to similar false claims litigation under state statutes. If we are unsuccessful in defending any such action, such action may have a material adverse effect on our business, financial condition and results of operations.

The difficulties of operating in international markets may harm sales of our products.

The international nature of our business subjects us and our representatives, agents and distributors to the laws and regulations of the jurisdictions in which they operate, and in which our products are sold and
used. The types of risks that we face in international operations include:



| |  |  | the imposition of governmental controls;
| | - |  | ----------------------------------------



| |  |  | logistical difficulties in managing international operations; and
| | - |  | -----------------------------------------------------------------



| |  |  | fluctuations in foreign currency exchange rates.
| | - |  | ------------------------------------------------

Our
international sales and operations may be limited or disrupted if we cannot successfully meet the challenges of operating internationally.

We may
acquire technologies, businesses or companies in the future, and these acquisitions could result in dilution to our shareholders and disruption of our business.

Entering into an acquisition could divert management attention. We also could fail to assimilate the acquired business or company, which could lead to higher operating expenses. Finally, our shareholders could be
diluted if we issue shares of our stock to acquire another company, business or technology.

Our business could suffer if we cannot attract and retain
the services of key employees.

We depend substantially upon the continued service and performance of our existing executive officers. We rely on key
personnel in formulating and implementing our product research, development and commercialization strategies. Our success will depend in large part on our ability to attract and retain highly skilled employees. We compete for such personnel with
other companies, academic institutions, government entities and other organizations. We may not be successful in hiring or retaining qualified personnel. If one or more of our key employees resigns, the loss of that employee could harm our business.
If we lose any key personnel, we may not be able to prevent the unauthorized disclosure or use of our technical knowledge or other trade secrets by those former employees, or successfully prevent them from competing against us despite our use of
confidentiality and non-compete agreements.

If we are sued in a product liability action, we could be forced to incur substantial defense costs, pay
substantial damages and the attention of our management team may be diverted from operating our business.

We manufacture medical devices that are used
on patients in surgery, and we may be subject to product liability lawsuits. In particular, the market for spine products has a history of product liability litigation. Under certain of our agreements with our distributors and hospital customers, we
indemnify the distributor or hospital from product liability claims. Any product liability claim



39



---

##### Table of Contents

brought against us, with or without merit, could result in the increase of our product liability insurance rates or the inability to secure coverage in the
future. In addition, we could incur substantial costs to defend these claims and would have to pay any amount awarded by a court in excess of policy limits. We maintain product liability insurance in the annual aggregate amount of up to $10,000,000,
although our insurance policies have various exclusions. Thus, we may be subject to a product liability claim for which we have no insurance coverage, in which case we may have to pay the entire amount of any defense costs or award. Even in the
absence of a claim, our insurance rates may rise in the future to a point where we may decide not to carry this insurance. A meritless or unsuccessful product liability claim would be time-consuming and expensive to defend and could divert
managements attention from our core business. A successful product liability claim or series of claims brought against us in excess of our coverage could have a material adverse effect on our business, financial condition and results of
operations.

Provisions of Pennsylvania law or our Articles of Incorporation may deter a third party from seeking to obtain control of us or may affect
your rights as a shareholder.

Certain provisions of Pennsylvania law could make it more difficult for a third party to acquire us, or could discourage
a third party from attempting to acquire us. These provisions could limit the price that certain investors might be willing to pay in the future for shares of our common stock. In addition, our Articles of Incorporation enable our board of directors
to issue up to 19,998,100 shares of preferred stock having rights, privileges and preferences as are determined by the board of directors. Accordingly, our board is empowered, without shareholder approval, to issue preferred stock with dividend,
liquidation, conversion, voting or other rights superior to those of holders of our common stock. For example, an issuance of preferred stock could:



| |  |  | adversely affect the voting power of the common shareholders;
| | - |  | -------------------------------------------------------------



| |  |  | make it more difficult for a third party to gain control of us;
| | - |  | ---------------------------------------------------------------



| |  |  | discourage bids for our common stock at a premium; or
| | - |  | -----------------------------------------------------



| |  |  | otherwise adversely affect the market price of our common stock.
| | - |  | ----------------------------------------------------------------

Our stock price may be volatile for many reasons, including fluctuations in our results of operations due to factors out of our control.

VITOSS, VITOSS FOAM, Bioactive VITOSS FOAM, VITAGEL, CELLPAKER, IMBIBE, CORTOSS and ALIQUOT are currently our only products that have received regulatory clearances or approvals for sale. VITOSS, IMBIBE syringes,
VITOSS FOAM, VITAGEL and CELLPAKER are cleared for sale in the U.S. and the European Union. Bioactive VITOSS FOAM and IMBIBE needles are cleared for sale in the U.S. CORTOSS and ALIQUOT are cleared for sale in the European Union. We launched VITAGEL
and CELLPAKER in 2005 after initially receiving rights to sell these products under a distribution agreement in 2004. We currently sell VITAGEL and CELLPAKER under a license agreement, the termination of which would have a material adverse effect on
our sales revenues. Future levels of our product sales and the timing of regulatory clearances and product introductions are difficult to predict, and product sales to date may not be indicative of future sales levels. Sales levels in Europe may
fluctuate due to seasonality of elective surgeries and the timing of any distributor stocking orders, and sales levels may fluctuate in the U.S. due to seasonality of elective surgeries and the timing of orders from hospitals. Our results of
operations may fluctuate significantly in the future

The results of our operations may fluctuate significantly from quarter to quarter and may not meet expectations of securities analysts and investors. This may cause our
stock price to be volatile.

In general, equity markets, including Nasdaq, have from time to time experienced significant price and volume fluctuations
that are unrelated to the operating performance of particular companies. These broad market fluctuations, including the following factors, may adversely affect the market price of our common stock:



| |  |  | changes in the financial guidance we provide to the investment community;
| | - |  | -------------------------------------------------------------------------



| |  |  | changes in stock market analyst recommendations regarding our stock;

Future sales of our common stock in the public market could adversely affect our stock price.

We cannot predict the effect, if any, that future sales of our common stock or the availability for future sales of shares of our common stock or securities convertible
into or exercisable for our common stock will have on the market price of our common stock prevailing from time to time. We have an effective registration statement on Form S-3 which allows us to sell up to approximately $67.5 million of securities
in one or more public offerings. The registration statement provides us with the flexibility to determine the type of security we choose to sell, including common stock, preferred stock, warrants with debt securities, as well as the ability to time
such sales when market conditions are favorable.

As of December 31, 2007, we had outstanding options to purchase 5,411,740 shares of our common stock
at a weighted average exercise price of $3.74 per share and 315,497 shares underlying restricted share and restricted stock unit grants issued to employees, directors and consultants pursuant to our 2007 Omnibus Equity Compensation Plan, and
outstanding warrants to purchase 2,567,063 shares of our common stock at a weighted average exercise price of $3.46 per share. In order to attract and retain key personnel, we may issue additional securities, including stock options, restricted
stock grants and shares of common stock, in connection with our equity compensation plan. The sale, or the availability for sale, of substantial amounts of common stock by our existing shareholders pursuant to an effective registration statement or
under Rule 144, through the exercise of registration rights or the issuance of shares of common stock upon the exercise of stock options or warrants, or the perception that such sales or issuances could occur, could adversely affect the prevailing
market prices for our common stock.

Center in Malvern, Pennsylvania. One lease is for approximately 30,900 square feet of unfinished space for a new warehouse. The initial term of this lease is
55 months commencing January 1, 2008, and the initial annual base rent under the lease is approximately $216,125. The other lease is for approximately 4,800 square feet of additional office and laboratory space. The initial term of this lease
is 55 months commencing January 1, 2008, and the initial annual base rent under the lease is approximately $43,593. We expect to complete renovations for both the warehouse and the office/laboratory space during the second quarter of 2008.

We believe our current manufacturing facility has the capacity to meet our commercial needs into 2010. In the fourth quarter of 2006, we commenced
renovations at sites we currently lease to expand our capacity to manufacture our products. While we expect to complete these renovations in the second quarter of 2008, we must obtain regulatory approval for the renovated facility before we can
market commercial product made there. We also have plans to start processing collagen for VITAGEL in-house within the next two years since our supplier of collagen for VITAGEL notified us in 2007 of its intent to shut down its collagen-processing
facility and cease supplying us with this collagen raw material (see  Manufacturing and Product Supply - Raw Material Supply under Item 1. BUSINESS, above). We accordingly commenced additional renovations in the first quarter of
2008 at sites we currently lease to establish a 10,700-square foot facility to process collagen used in the manufacture of our VITAGEL product. While we expect to complete these renovations by the first quarter of 2009, we must also obtain
regulatory approval for this facility before we can market commercial products made there. Based on our current commercial needs and estimated requirements for the possible U.S. launch of CORTOSS, we do not anticipate the need in the foreseeable
future for additional capacity once our existing facilities have been fully renovated.

We conduct our international sales and marketing activities through
administrative office space in Leuven, Belgium, which we have leased through May 2009.



|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

On March 4, 2008, MO-SCI Corporation filed a complaint against us in the United States
District Court for the Eastern District of Pennsylvania. The plaintiff alleges breach of a purported non-disclosure agreement, fraud, conversion of confidential and proprietary information and trade secrets, and misappropriation of trade secrets
purportedly related to glass components that may be used in certain of our products and the processing of such glass. The plaintiff seeks unspecified monetary damages and injunctive relief. On March 14, 2008, the court scheduled a hearing for April
16, 2008 on plaintiffs motion for preliminary injunction. The Company believes the plaintiffs claims are without merit and intends to vigorously defend the case.

As of March 7, 2008 there were 223 holders of record for shares of our Common Stock. Since a portion of our
Common Stock is held in street or nominee name, we are unable to determine the exact number of beneficial holders. On March 7, 2008, the last reported sale price of the Common Stock as reported by Nasdaq was $2.65 per share.

We have never declared or paid cash dividends on shares of our Common Stock and do not intend to pay any cash dividends in the foreseeable future on
shares of our Common Stock.

FORWARD-LOOKING
STATEMENTS

Forward-looking statements give our current expectations, forecasts of future events or goals. You can identify these statements by the fact
that they do not relate strictly to historical or current facts. These statements may include words such as may, will, anticipate, estimate, expect, project, intend,
plan, believe, seek and other words and terms of similar meaning in connection with any discussion of future operating or financial performance. Any or all of our forward-looking statements in this Form 10-K may
turn out to be wrong. They can be affected by inaccurate assumptions we might make, or by known or unknown risks and uncertainties. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially. There are
important factors that could cause actual events or results to differ materially from those expressed or implied by forward-looking statements including, without limitation, the development, regulatory approval, demand and market acceptance of our
products; results of our CORTOSS pivotal clinical trial in the U.S.; whether the FDA will require our CORTOSS 510(k) application to contain two-year follow up data for a greater percentage of the patients in the pivotal study than that which is
reflected in the application as originally filed with the FDA or for all of the patients in the pivotal study; availability of raw materials; the cost to expand our manufacturing and operating facilities; the development of our sales network;
capital expenditures; future liquidity; uses of cash; sales product mix and related margins; our ability to manage our manufacturing facilities and requirements; inventory levels; development costs for existing and new products; equity compensation
expense; changes in market interest and foreign currency exchange rates; fluctuations in our stock price; and the other risk factors addressed in ITEM 1A. Risk Factors in this Annual Report on Form 10-K.

We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. You are advised,
however, to consult any further disclosures we make on related subjects in our filings with the U.S. Securities and Exchange Commission (the SEC). This discussion is provided as permitted by the Private Securities Litigation Reform Act
of 1995.

OVERVIEW

Product sales for 2007 increased 24% to $58,045,676 from $46,828,047 in 2006. Increased product sales principally reflect increased sales of our VITOSS® FOAM
and VITAGEL® products in the U.S. Nevertheless, we anticipate our product sales will remain insufficient to support our present operations at expected spending levels. We expect to continue
to incur significant operating losses for the foreseeable future as we plan to continue to expand our sales and marketing activities, pursue research and product development efforts, further develop our manufacturing capabilities and attempt to
increase manufacturing efficiencies.

The following summarizes our principal cash commitments at December 31, 2007 and, as of the date of this report,
our principal anticipated expenditures:

| |  |  | Allergan Agreement.We expect to pay Allergan approximately $6.6 million during the fourth quarter of 2008 for the acquisition of collagen raw material,
collagen processing equipment and a technology license for collagen processing know-how under a Supply and License Agreement. We expect to pay the purchase price to Allergan through the use of cash, cash equivalents and/or proceeds from the sale of
promissory notes under our debt facility with LB I Group Inc. See Note 14 to our consolidated financial statements included in this report for additional information.

| |  |  | Expansion of manufacturing capacity and other facility renovations.We expect to spend approximately $5.6 million for plant renovations and equipment during
2008 to expand our capacity to manufacture VITAGEL and ancillary products such as ALIQUOT, IMBIBE and CELLPAKER, and renovate warehouse and research and development laboratory space at sites we currently lease. We plan to finance the renovations and
equipment through cash on hand.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Agreement with Kensey. Approximately 61% of our product sales during the year ended December 31, 2007 was from products based upon our VITOSS FOAM
platform co-developed with Kensey. As of December 31, 2007, we owed Kensey $2,569,004 for manufactured product inventory and royalties, which amount is included in accounts payable and other accrued expenses on the Consolidated Balance Sheets.
See Note 14 to our consolidated financial statements included in this report for additional information.

| |  |  | Operations. We expect to use cash, cash equivalents and investments to fund our operations until we generate sufficient cash to support our operations, if
ever. See Note 14 to our consolidated financial statements included in this report for additional information on future minimum rental payments under operating leases. In addition, we may hire additional direct sales representatives to support not
only the growth of our existing products, but to plan ahead for the possible clearance and commercial launch of CORTOSS in the U.S. While we believe that our investment in our sales force may also bring opportunities to in-license or distribute
additional products, we expect to continue spending for research and development for new products. We also expect to build inventory in 2008 to plan for the possible clearance and launch of CORTOSS in the U.S. and to establish a strategic collagen
reserve for VITAGEL.

| |  |  | CORTOSS clinical study and research and development. We expect to incur approximately $1.6 million in external costs during 2008 and 2009 in the completion
of the CORTOSS pivotal clinical study in the U.S. Subsequent to completion of patient enrollment for the study in February 2007 and the submission of the CORTOSS 510(k) filing to the FDA in January 2008, we will continue to monitor the patients and
collect further clinical data until all enrolled patients have completed a 24-month follow

| | up period, which is expected to occur in February 2009. During 2008, we expect our primary use of cash, cash equivalents and investments for
research & development activities will relate to costs associated with clinical trials in the U.S. and research and development for CORTOSS.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Debt service obligation.We expect to pay approximately $625,000 in quarterly interest payments during each quarter of 2008 under the $25,000,000 note issued
on July 30, 2007 under our debt facility with LB I Group Inc.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We believe our existing cash, cash equivalents, and investments of
$48,407,888 as of December 31, 2007 will be sufficient to meet our currently estimated operating and investing requirements for the foreseeable future.

On February 15, 2007, we sold our assets associated with the Endoskeleton TA Vertebral Body Replacement structural device product line for $458,480. As a result of the sale, we no longer manufacture or sell Endoskeleton products. We
recorded revenues for the years ended December 31, 2007, 2006 and 2005 of $0, $902,593, and $486,588, respectively, for sales of Endoskeleton products.

CRITICAL ACCOUNTING POLICIES

The preparation of the consolidated financial statements requires us to make assumptions, estimates and
judgments that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities as of the date of our consolidated financial statements, and the reported amounts of revenues and expenses during the
reporting periods. By their nature, these assumptions, estimates and judgments are subject to an inherent degree of uncertainty. We use authoritative pronouncements, historical experience and other assumptions as the basis for making estimates.
Actual results could differ from those estimates. The critical accounting policies addressed below have been reviewed with the Audit Committee and reflect our most significant judgments and estimates used in the preparation of our consolidated
financial statements.

Revenue Recognition

Revenue is not
recognized until persuasive evidence of an arrangement exists, performance has occurred, the sales price is fixed or determinable and collection is probable. In the U.S., product sales revenue is recognized upon either receipt of documentation from
the customer indicating their consumption of product from consigned inventory or shipment of purchased product to the customer. Outside the U.S., revenue from product sales is primarily recognized upon receipt of our product by our independent
stocking distributors. Outside the U.S., we do not allow product returns or exchanges. We have no obligations to our customers once title has been transferred. Both our U.S. customers and our independent stocking distributor customers outside of the
U.S. are generally required to pay on a net 30-day basis and payment discounts are not offered.

Allowance for Doubtful Accounts

We maintain an accounts receivable allowance for an estimated amount of losses that may result from a customers failure to pay for product purchased. We analyze accounts receivable and historical bad debts, customer concentrations and
changes in customer payment patterns when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of our customers were to deteriorate and result in an impairment of their ability to make payments, additional
allowances may be required.

Inventory

Inventory is stated at
the lower of cost or market value using the first-in first-out basis, or FIFO. A provision is recorded to reduce the cost of inventories to the estimated net realizable values, if required. In accordance with Statement of Financial Accounting
Standards (SFAS) No. 2, Accounting for Research and Development Costs, the costs of producing inventory in the reporting periods prior to the receipt of regulatory approval or clearance are recorded as research and
development expense.

Revenue Interest Obligation

During
October 2001, we completed a $10,000,000 product development and equity financing with Paul Capital Royalty Acquisition Fund, L.P., which was subsequently assigned to Royalty Securitization Trust I (Royalty Trust). In March 2002, we
amended the original financing, which resulted in a one time increase to the revenue interest obligation of $1,945,593, increasing the balance of the revenue interest obligation to $7,167,700. The revenue interest obligation is accounted for in
accordance with Emerging Issues Task Force (EITF) Issues No. 88-18, Sales of Future Revenues. On July 30, 2007, we repurchased the revenue interest obligation from Royalty Trust. As a result, we are no longer
obligated to pay royalties on our products subject to the revenue interest obligation, including VITOSS and CORTOSS. The repurchase price for the revenue interest obligation consisted of a payment of $20,000,000 in cash and 1,136,364 shares of our
common stock valued at $3.32 per share, which was the market price per share on the date of the transaction. As a result of the repurchase, we recorded a charge of $16,605,029 in the third quarter of 2007 to account for the difference between the
repurchase price valued at $23,772,729 and the $7,167,700 carrying value of the revenue interest liability on our Consolidated Balance Sheet as of the date of the transaction. In connection with the repurchase, Royalty Trust assigned to us all of
its interest under the agreements relating to the revenue interest obligation, effectively terminating the security interest in certain of our assets and the pledge of stock of our wholly-owned subsidiary that we had granted Royalty Trust to secure
our obligations under the revenue interest agreement.

The products that were subject to the revenue interest have only been approved or cleared and
marketed for the past several years or are still under development. For these reasons, as of July 29, 2007, we could not make a reasonable estimate of future revenues and payments that could have become due to Royalty Trust under this
financing. Accordingly, we did not amortize any portion of the liability attributable to the revenue interest obligation, and we charged revenue interest expense in accordance with EITF No. 88-18 for the revenue interest due to Royalty Trust as
revenues subject to the revenue interest obligation were recognized (see Note 7). Revenue interest expense of $756,703, $1,179,466 and $989,287 has been recorded for the years ended

December 31, 2007, 2006 and 2005, respectively.

Income
Taxes

We account for income taxes in accordance with an asset and liability approach requiring the recognition of deferred tax assets and liabilities for
the expected tax consequences of events that have been recognized in the financial statements or tax returns. Deferred tax assets and liabilities are recorded without consideration as to their ability to be realized. The deferred tax asset includes
net operating loss and credit carry forwards, and the cumulative temporary differences related to certain research and patent costs, which have been charged to expense in our consolidated statements of operations but have been recorded as assets for
tax return purposes. The portion of any deferred tax asset, for which it is more likely than not that a tax benefit will not be realized, must then be offset by recording a valuation allowance against the asset. See Note 13 to our consolidated
financial statements included in this report for additional information.

Accounting for Stock Options Issued to Employees

In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 123R,
Share-Based Payment. (SFAS No. 123R). This statement revised SFAS No. 123, Accounting for Stock-Based Compensation (SFAS No. 123), and requires companies to expense the
value of employee stock options and similar awards. The effective date of this standard for the Company was January 1, 2006. Under SFAS No. 123R, we are required to expense stock options in our Consolidated Statements of Operations. We
have selected the Black-Scholes option-pricing model, on a modified prospective transition method, as permitted by SFAS No. 123R, and therefore have not restated our financial results for prior periods. Under this transition method, stock-based
compensation expense for the year ended December 31, 2006 includes the remaining compensation expense for all stock-based compensation awards granted prior to, but not yet vested as of, January 1, 2006 based on the grant date fair value
estimated in accordance with the original provisions of SFAS No. 123. These amounts are being amortized based upon a graded vesting schedule in accordance with FASB Interpretation No. 28, Accounting for Stock Appreciation Rights
and Other Variable Stock Option or Award Plans. Stock-based compensation expense for all stock-based compensation awards granted to employees subsequent to January 1, 2006 is based on the grant date fair value estimated in accordance
with the provisions of SFAS No. 123R and amortized on a straight-line basis over the requisite service period of the award.

Prior to the adoption of
SFAS No. 123R, we applied the intrinsic-value-based method of accounting prescribed by Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB No. 25), and related
interpretations to account for our stock option plans. Under this method, compensation expense was computed and recorded on the date of grant for the intrinsic value related to stock options granted, reflected by the difference between the option
exercise price and the fair market value of the underlying shares of Common Stock on the date of grant. Accordingly, because the exercise price of our employee stock options equaled the market price of the underlying stock on the date of grant, no
compensation expense was recognized.

The Companys Board of Directors approved the acceleration of vesting for all out-of-the-

money unvested stock options held by current employees, officers or directors on November 29, 2005 under the Companys 1993 Stock Option Plan
and Amended and Restated 1997 Equity Compensation Plan. An option was considered out-of-the-money if the stated exercise price was greater than $3.50 per share, the closing sale price of the Companys Common Stock on
November 29, 2005. As a result of this action, vesting of options to purchase approximately 1,110,000 shares of our Common Stock were accelerated. The decision to accelerate the vesting of these options was made primarily to reduce compensation
expense that might be recorded in future periods following our adoption of SFAS No. 123R. The pro forma table for the years ended December 31, 2005 and 2004 set forth in Note 2 to the Consolidated Financial Statements includes this 2005
acceleration. If vesting of these options had not been accelerated, expense related to these options would have been as follows: $1,600,000 in 2006, $1,400,000 in 2007, $1,200,000 in 2008 and $800,000 in 2009.

Accounting for Derivative Liability Associated with Non-Employee Stock Options

Historically, the common stock purchase options that we granted to non-employee consultants as compensation for services rendered were fully vested on the date of the grant. Upon adoption of SFAS No. 123R, during the service and
vesting period, these options are accounted for under SFAS No. 123R. However, once the service period terminates, these options are then accounted for in accordance with EITF Issue No. 00-19, Accounting for Derivative Financial
Instruments Indexed to, and Potentially Settled in a Companys Own Stock (EITF No. 00-19), from the date the service/vesting period terminates through the expiration of the option or until it is exercised, whichever is
earlier. In certain circumstances, these awards may have to be settled in cash. Accordingly, effective January 1, 2006, we reclassified from equity to liabilities the aggregate Black-Scholes value of our fully-vested non-employee consultant
stock options that were outstanding as of January 1, 2006. In addition, we are required to record a fair value adjustment at the end of each quarter for the change in the Black-Scholes value of our fully-vested non-employee consultant stock
options outstanding.

Our stock price may be volatile and may fluctuate. Since we cannot determine what our stock price will be at the end of future
quarters, we cannot estimate the impact of EITF No. 00-19 on our Consolidated Balance Sheet and Consolidated Statements of Operations in the future. An increase to our stock price as of the last day of a given quarter, as compared to our stock price
as of the last day of the prior quarter, may result in an increase to the liability recorded to our Consolidated Balance Sheet and an increase to operating expenses recorded in our Consolidated Statements of Operations. Conversely, a decrease to our
stock price as of the last day of a given quarter, as compared to our stock price as of the last day of the prior quarter, may have the opposite effect. Additionally, any subsequent changes to the assumptions used in the Black-Scholes model to
estimate the fair value of these non-employee consultant options will impact the effect of EITF No. 00-19 on our Consolidated Balance Sheet and Consolidated Results of Operations.

LIQUIDITY AND CAPITAL RESOURCES

We have experienced negative operating cash flows since our inception, and we have funded our operations primarily from the proceeds we received from sales of our common stock and other securities. At
December 31, 2007, we had cash, cash equivalents and investments of $48,407,888, which includes the remaining balance of net proceeds we received from our 2007 issuances and sales of shares of our common stock for $32,198,758 and our notes and
warrants for $25,000,000. During 2007, our operating activities used $14,173,620 of cash.

Discussion of Cash Flows

Cash Flows Used in Operating Activities

Net
cash used in operating activities for the year ended December 31, 2007 was $14,173,620, compared to $16,037,621 used in operating activities for the year ended December 31, 2006. Our operating cash outflows for 2007 primarily were used to
fund our operations and include $6,228,630 used to fund increases in inventories as well as funding for the expansion of our field sales team and increased sales commissions on our growing product sales. Operating cash outflows for 2007 were offset
in part by operating cash inflows generated by sales of our products. In addition, increases in accounts payable of $2,393,340 were a source of on operating cash flows in 2007.

We expect to continue to focus our efforts on sales growth under our VITOSS and VITAGEL product platforms in 2008, and launched Bioactive VITOSS FOAM in the first quarter of 2008. We may continue to add direct sales
representatives to our organization for those territories in the U.S. where either we do not currently have independent distributor coverage or the territory is underserved in an effort to increase sales of our VITOSS and VITAGEL product lines and
to plan ahead for the possible clearance of CORTOSS in the United States. Also, we intend to fund studies to collect and publish post-clinical data relating to the performance of VITOSS to support our marketing and sales efforts.

We expect to continue to use cash, cash equivalents and investment proceeds to fund our operations until we are profitable, if ever. We anticipate that our product sales
for the foreseeable future will remain insufficient to support our present operations at expected spending levels. As a result, we expect to continue to incur significant operating losses for the foreseeable future as we continue to expand our sales
and marketing activities, pursue product development efforts and further develop our manufacturing capabilities.

We expect our primary use of cash for
research and development activities in 2008 to be directed to CORTOSS. During 2008 and 2009, we expect to incur approximately $1,600,000 in external costs to complete our pivotal clinical study in the U.S. for CORTOSS. The overall level of our
research and development expense in future periods will depend upon the development status and cost of products currently in our pipeline and any new products that we may determine to pursue in the future. We may also incur additional expenses to
support the U.S. launch of CORTOSS if it receives FDA clearance.

Our operating cash requirements are dependent heavily upon the timing of receipt of FDA
510(k)

clearance for new products, the rates at which we add new direct sales representatives and our field sales network generates sales, our product sales mix as
relative increases in sales of our lower margin products tends to increase our cash needs, the amount of inventory, including raw materials and work-in-process, we maintain to support product sales and anticipated product launches and the timing of
subsequent product launches and market acceptance of our new products. Accordingly, in 2008, our operating cash requirements will continue to be subject to quarterly volatility.

Cash Flows Used in Investing Activities

Net
cash used in investing activities was $27,557,306 for the year ended December 31, 2007 compared to $3,326,524 for the year ended December 31, 2006. The increase in cash used in investing activities in 2007 primarily reflects our investment
of the $35,454,219 of net cash provided by our financing activities in 2007 in highly liquid investment grade marketable securities, as described below. In addition, we spent $2,605,825 in 2007 to purchase equipment and leasehold improvements to
support further expansion of our product development and manufacturing capabilities for VITAGEL and VITOSS, as compared to $1,378,271 spent in 2006 for equipment and leasehold improvements. Net cash used in investing activities for the year ended
December 31, 2006 also reflects our investment of a portion of the $27,094,149 of net cash provided by our financing activities in 2006, described below, as well as our purchase for $9,000,000 of the profit-sharing royalty rights for VITAGEL
and CELLPAKER from Angiotech. As a result of this purchase, we no longer pay Angiotech royalties for VITAGEL product sales. The $9,000,000 purchase price was recorded as a license right intangible on our consolidated balance sheets and is being
amortized based upon the greater cost of (a) straight-line amortization through July 31, 2017 and (b) actual units sold in a given period in relation to the total estimated units to be sold over the expected life of the applicable
patent, which expires on July 31, 2017.

We invest our excess cash in highly liquid investment-grade marketable securities, including corporate
commercial paper and U.S. government agency bonds. As of December 31, 2007 and 2006, cash, cash equivalents and investments consisted of the following:

We expect to spend approximately $5,600,000 during 2008 to expand our manufacturing facility and for related leasehold
improvements and capital equipment. In addition, we are committed contractually to spend approximately $5,300,000, expected to be incurred in 2008, to acquire a technology license related to collagen processing for our VITAGEL product and to
purchase related equipment from Allergan. See Note 14 to our consolidated financial statements included in this report. We plan to fund these amounts through liquidation of cash equivalents and investments or from the proceeds of our issuance and
sale of additional notes and warrants under our debt facility with LB I Group Inc.

Cash Flows Provided by Financing Activities

Net cash provided by financing activities for the year ended December 31, 2007 was $35,454,219 compared to $27,094,149 for the year ended
December 31, 2006. The increase of $8,360,070 for 2007 reflects primarily our issuance and sale of an aggregate of 12,317,066 shares of our common stock at $2.64 per share to raise aggregate net proceeds of $32,198,758 and notes and warrants
for proceeds of $25,000,000 as well as our use of $20,000,000 to pay the cash portion of the repurchase price for the Royalty Trust revenue interest obligation. We have used, and intend to continue using, the net proceeds from our issuances and
sales of securities in 2007 for product development, sales force expansion, increase of manufacturing capacity and for working capital and other general corporate purposes. In 2006, we issued and sold 8,819,128 shares of our common stock for net
proceeds of $26,573,492.

We do not expect sales to generate cash flows in excess of operating expenses for the foreseeable future, if ever. Until we
achieve sales levels to enable us to fund operating expenses, we expect to continue to use cash, cash equivalents and investment proceeds to fund operating and investing activities. As of December 31, 2007, we had cash, cash equivalents and
investments of $48,407,888, and we had $20,000,000 available for additional borrowing under our debt facility with LB I Group Inc. We believe our existing cash, cash equivalents and investments, together with amounts available to us under our debt
facility, will be sufficient to meet our currently estimated operating and investing requirements for the foreseeable future. The extent and timing of proceeds from future stock option and warrant exercises, if any, are primarily dependent upon
future trading prices for our common stock and the expiration dates of these instruments.

which commenced June 1, 2006 and terminates July 2012, and extended an existing office space lease from October 2007 until July 2012. We entered into
two leases in January 2008 for space located in the Great Valley Corporate Center in Malvern, Pennsylvania. One lease is for approximately 30,900 square feet of unfinished space for a new warehouse. The initial term of this lease is 55 months
commencing January 1, 2008, and the initial annual base rent under the lease is approximately $216,125. The other lease is for approximately 4,800 square feet of additional office and laboratory space. The initial term of this lease is 55
months commencing January 1, 2008, and the initial annual base rent under the lease is approximately $43,593. We expect to complete renovations for both the warehouse and the office/laboratory space during the second quarter of 2008. As of
December 31, 2007, future minimum rental payments under operating leases are as set forth in the table above under the caption Leases.

Notes Payable and Capital Lease Obligations.

On July 30, 2007, we entered into a $45,000,000 senior secured note purchase facility
with LB I Group Inc., an affiliate of Lehman Brothers Inc. Notes issued under the facility are due July 30, 2012. We initially issued $25,000,000 of our 10% senior secured notes under the facility and used most of the proceeds to repurchase a
revenue interest obligation.

Borrowings under the facility are guaranteed by us and one of our wholly-owned subsidiaries. The facility is secured by a
first priority lien on substantially all of our assets (including intellectual property) other than those exclusively related to CORTOSS and ALIQUOT. We are required to make quarterly interest only payments to the note holder. Outstanding principal
amounts under the notes bear annual interest at 10%, provided that interest shall accrue at the rate of 12% per year during the continuance of any event of default and shall be payable on demand. As of December 31, 2007, we expect to incur
quarterly interest expense of $625,000 during 2008.

Allergan Agreement.We expect to pay Allergan approximately $6.6 million during the fourth
quarter of 2008 for the acquisition of collagen raw material, collagen processing equipment and a technology license for collagen processing know-how under a Supply and License Agreement. We expect to pay the purchase price to Allergan through the
use of cash, cash equivalents and/or proceeds from the sale of promissory notes under our debt facility with LB I Group Inc. See Note14 to our consolidated financial statements included in this report for additional information.

Agreement with Kensey Nash Corporation. See above discussion under OVERVIEW, above.

RESULTS OF OPERATION

This section should be read in conjunction with the detailed discussion under Liquidity
and Capital Resources. As noted above, we expect to continue to incur operating losses in the future as we continue our product development efforts.

Comparison of the Year Ended December 31, 2007 to the Year Ended December 31, 2006

Product Sales. Product sales for 2007
increased 24% to $58,045,676 as compared to $46,828,047 for the same period in 2006. Sales growth in 2007 was primarily attributable to increased sales of

VITOSS FOAM and VITAGEL product portfolios in the U.S. as we further develop our U.S. field sales network. Approximately 61% and 60% of our product sales
during the years ended December 31, 2007 and 2006, respectively, were from products based upon our VITOSS FOAM platform co-developed with Kensey Nash Corporation (see Note 12 to our consolidated financial statements included in this report for
additional information). VITAGEL, which was launched at the start of 2005, contributed approximately 21% of our product sales during the year ended December 31, 2007, as compared to approximately 17% of our product sales during the year ended
December 31, 2006.

For the years ended December 31, 2007 and 2006, 93% of product sales were in the U.S., primarily from sales of VITOSS,
VITAGEL and IMBIBE. The remaining sales, during 2007 and 2006, were a result of VITOSS, CORTOSS and ALIQUOT sales outside the U.S., primarily in Europe.

Gross Profit. Gross profit for the years ended December 31, 2007 and 2006 was $37,502,313 and $29,045,472, respectively. As a percentage of sales, gross profit was 65% for 2007, as compared to 62% for 2006. The increase in the
gross margin for 2007 as compared to 2006 primarily reflects improved manufacturing efficiencies and lower VITAGEL royalty expense. Accordingly, our gross margins may fluctuate from quarter to quarter based on the mix of products sold from period to
period.

Operating Expenses. Operating expenses for the years ended December 31, 2007 and 2006 were $51,080,283 and $46,005,939, respectively,
which represents an 11% increase from 2006 to 2007 as compared to a 24% increase in product sales and a 29% increase in gross profit during the same period. Operating expenses for the years ended December 31, 2007 and 2006 include executive
severance of $662,000 and $0, respectively, and non-cash compensation expense of $1,220,217 and $1,562,825, respectively, related to stock options, restricted stock grants and restricted stock units. In addition, operating expenses for the year
ended December 31, 2007 include a net non-cash charge of $475,770 for non-employee consultant stock options, while 2006 expenses were reduced by a non-cash fair value adjustment of $535,469 for our fully-vested non-employee consultant stock
options then outstanding. Operating expenses were 88% and 98% of product sales for 2007 and 2006, respectively.

General and administrative expenses for
2007 increased 20% to $10,700,612 from $8,939,005 for 2006, primarily due to executive severance, legal costs, and charges associated with stock options and restricted stock issued to current and former Board members. General and administrative
expenses for 2007 included non-cash employee compensation expense of $839,969, as compared to $631,827 for the year 2006, relating to stock options and restricted stock units awarded to employees. General and administrative expenses were 18% and 19%
of product sales for 2007 and 2006, respectively.

Selling and marketing expenses were $33,944,777 for the year ended December 31, 2007, a 19%
increase from $28,595,431 for the year ended December 31, 2006. Selling and marketing expenses increased for the year ended December 31, 2007 primarily due to higher salary and benefit costs incurred by expanding our field sales team in
order to support the growth of U.S product sales, as well as higher commissions paid in the U.S. as a result of increased product sales in 2007. Our field sales team increased from 92 employees at December 31, 2006, of which 76 were direct
sales representatives, to 98 employees at December 31, 2007, of which 83

were direct sales representatives. Selling and marketing expenses for the year ended December 31, 2007 include non-cash employee compensation expense of
$306,959 relating to stock options and restricted stock units awarded to employees and a non-cash adjustment of $355,343 for our fully-vested non-employee consultant stock options outstanding. Selling and marketing expenses for the year ended 2006
included non-cash employee compensation expense of $535,646 relating to stock options and restricted stock units awarded to employees, while expenses were reduced by non-cash fair value adjustments of $499,455 for our fully-vested non-employee
consultant stock options outstanding. Selling & marketing expenses were 58% and 61% of product sales for 2007 and 2006, respectively.

Research & development expenses decreased 24% to $6,434,894 for the year ended December 31, 2007 from $8,471,503 for the same period in 2006. The decrease for the year ended December 31, 2007 was primarily due to lower
costs associated with our CORTOSS product development and U.S. clinical trials. Research & development expenses for 2007 included non-cash employee compensation expense of $73,289, as compared to $395,352 for the year 2006, relating to
stock options and restricted stock units awarded to employees. Research & development expenses were 11% and 18% of product sales for 2007 and 2006, respectively.

Net other expense.Net other expense included a charge for the revenue interest obligation repurchase, a gain on an asset sale, interest income, interest expense, revenue interest expense and an
income tax benefit. We recorded $16,304,193 and $503,172 of net other expense for the years ended December 31, 2007 and 2006, respectively. The increase in net other expense is primarily a result of the charge for the revenue interest
obligation repurchase.

Comparison of the Year Ended December 31, 2006 to the Year Ended December 31, 2005

Product Sales. Product sales for 2006 increased 35% to $46,828,047 as compared to $34,679,298 for the same period in 2005. Sales growth in 2006 was primarily
attributable to increased sales of VITOSS FOAM and VITAGEL product portfolios in the U.S. as we further develop our U.S. field sales network. Approximately 60% of our product sales during each of the years ended December 31, 2006 and 2005 were
from products based upon our VITOSS FOAM platform co-developed with Kensey Nash Corporation (see Note 12 to our consolidated financial statements included in this report for additional information). VITAGEL, which was launched at the start of 2005,
contributed approximately 17% of our product sales during the year ended December 31, 2006, as compared to approximately 9% of our product sales during the year ended December 31, 2005.

For the years ended December 31, 2006 and 2005, 93% of product sales were in the U.S., primarily from sales of VITOSS, VITAGEL and IMBIBE. The remaining sales,
during 2006 and 2005, were a result of VITOSS, CORTOSS and ALIQUOT sales outside the U.S., primarily in Europe.

Gross Profit. Gross profit for the
years ended December 31, 2006 and 2005 was $29,045,472 and $22,027,720, respectively. As a percentage of sales, gross profit was 62% for 2006, as compared to 64% for 2005. The decline in the gross margin for 2006 as compared to 2005 primarily
reflects the shift in product mix toward VITAGEL product sales, which have a lower gross margin as compared to our other products. Accordingly, our gross margins may fluctuate from quarter to quarter based on the mix of products sold from period to
period.

Operating Expenses. Operating expenses for the years ended December 31, 2006 and 2005 were $46,005,939 and
$34,955,082, respectively, which represents a 32% increase from 2005 to 2006 as compared to a 35% increase in product sales during the same period. Operating expenses for the year ended December 31, 2006 include non-cash employee compensation
expense of $1,536,069 relating to stock options awarded to employees. In addition, operating expenses for the year ended December 31, 2006 were reduced by a non-cash fair value adjustment of $535,469 for our fully-vested non-employee consultant
stock options outstanding.

General and administrative expenses for 2006 increased 34% to $8,939,005 from $6,661,628 for 2005, primarily due to increased
finance and information technology personnel to support business growth and compliance activities, non-cash employee compensation expense of $605,071 related to stock options awarded to employees, and higher information technology infrastructure
expenses. General and administrative expenses were 19% of product sales for both 2006 and 2005.

Selling and marketing expenses were $28,595,431 for the
year ended December 31, 2006, a 35% increase from $21,126,567 for the year ended December 31, 2005. Selling and marketing expenses increased for the year ended December 31, 2006 primarily due to higher salary and benefit costs
incurred by expanding our field sales team in order to support the growth of U.S product sales, as well as higher commissions paid in the U.S. as a result of increased product sales in 2006. Our field sales team increased from 59 employees at
December 31, 2005, of which 47 were direct sales representatives, to 92 employees at December 31, 2006, of which 76 were direct sales representatives. Selling & marketing expenses were 61% of product sales for both 2006 and 2005.
Selling and marketing expenses for the year ended December 31, 2006 include non-cash employee compensation expense of $535,866 relating to stock options awarded to employees and were reduced by a non-cash fair value adjustment of $499,455 for
our fully-vested non-employee consultant stock options outstanding.

Research & development expenses increased 18% to $8,471,503 for the year
ended December 31, 2006 from $7,166,887 for the same period in 2005. The increase for the year ended December 31, 2006 was primarily due to costs associated with our CORTOSS product development and U.S. clinical trials, as well as VITAGEL
product development. Research and development expenses for the year ended December 31, 2006 include non-cash employee compensation expense of $395,132 related to stock options awarded to employees.

Net other expense. Net other expense includes interest income, interest expense and revenue interest expense. We recorded $503,172 and $435,979 of
net other expense for the years ended December 31, 2006 and 2005, respectively. The increase in net other expense is primarily attributed to increased revenue interest expense of $190,179 incurred under the arrangement with Royalty Trust due to
increased product sales, partially offset by lower interest expense of $75,399 primarily related to amortization of investments and higher interest income of $47,587 as a result of higher average cash, cash equivalent, and investment balances.

|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Foreign
Currency Risk

The functional currency for our European branch operation is the Euro. Accordingly, in accordance with SFAS No. 52 Foreign
Currency Translation, all assets and liabilities related to this operation are translated at the current exchange rates at the end of each period. Revenues and expenses are translated at average exchange rates in effect during the period. The
resulting translation adjustments are accumulated in a separate component of shareholders equity (accumulated other comprehensive income). Foreign currency transaction gains and losses, if any, are included in results of operations.

As of December 31, 2007, our total exposure to foreign currency risk in U.S. dollar terms was approximately $3,630,000, or 4%, of our total assets.
The potential impact of a hypothetical 10% decline in the Euro foreign exchange rate would result in a total decline in the fair value of our assets of approximately $363,000 at December 31, 2007.

Market Risk

We may be exposed to market risk through changes in market
interest rates that could affect the value of our short-term and long-term investments; however, we do not believe the fair value of our investment portfolio or related income would be significantly affected by changes in interest rates due mainly
to the relatively short-term nature of the majority of our investment portfolio.

As of December 31, 2007 and 2006, our investments consisted of
highly liquid investment-grade marketable securities including corporate commercial paper and U.S. government agency bonds. The impact on our future interest income and future changes in investment yields will depend on the gross amount of our
investments and various external economic factors.

Evaluation of Disclosure Controls and
Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure
controls and procedures as of December 31, 2007. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2007 our disclosure controls and procedures are functioning effectively
to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the
SECs rules and forms and (ii) accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding disclosure.

MANAGEMENTS ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Orthovita, Inc. (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Securities Exchange Act of 1934. The
Companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. The Companys internal control over financial reporting includes those policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the Company; provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, provide
reasonable assurance that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use, or disposition of the Companys assets that could have a material effect on the financial statements.

Because of its
inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of
changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management evaluated the Companys internal
control over financial reporting as of December 31, 2007. In making this assessment, management used the framework established inInternal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO). Managements assessment included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of our internal control over financial reporting.
Management reviewed the results of its assessment with the Audit Committee of the Companys Board of Directors. Based on that assessment and based on the criteria in the COSO framework, management has concluded that,

as of December 31, 2007, the Companys internal control over financial reporting was effective.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting during the
quarter ended December 31, 2007, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

Orthovita, Inc.:

We have audited Orthovita, Inc. and subsidiaries (the
Company) internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO).Orthovita, Inc. and subsidiaries management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the
accompanying Managements Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting,
assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary
in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is
a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A

companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Orthovita, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control -
Integrated Framework issued by the COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States), the consolidated balance sheets of Orthovita, Inc. and subsidiaries as of December 31, 2007 and 2006, and the related consolidated statements of operations, shareholders equity and comprehensive loss, and cash flows
for each of the years in the three-year period ended December 31, 2007, and our report dated March 17, 2008 expressed an unqualified opinion on those consolidated financial statements.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

Orthovita, Inc.:

We have audited the accompanying consolidated balance
sheets of Orthovita, Inc. and subsidiaries (the Company) as of December 31, 2007 and 2006, and the related consolidated statements of operations, shareholders equity and comprehensive loss, and cash flows for each of the years in the
three-year period ended December 31, 2007. These consolidated financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our
audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial
position of Orthovita, Inc. and subsidiaries as of December 31, 2007 and 2006, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2007, in conformity with U.S.
generally accepted accounting principles.

As discussed in Note 2 to the Consolidated Financial Statements, effective January 1, 2006, the Company adopted
the fair value method of accounting for stock-based compensation as required by Statement of Financial Accounting Standards No. 123R, Share-Based Payment.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States), Orthovita, Inc. and subsidiaries internal control over financial reporting as of December 31, 2007, based on criteria established inInternal Control - Integrated Frameworkissued by the Committee of Sponsoring Organizations of
the Treadway Commission (COSO), and our report dated March 17, 2008 expressed an unqualified opinion on the effectiveness of the Companys internal control over financial reporting.

ORTHOVITA, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. The Company:

Orthovita, Inc. and subsidiaries (the
Company) is a spine and orthopedic biosurgery company with proprietary biomaterials and biologic technologies for the development and commercialization of synthetic, biologically active, tissue engineering products. We develop and market
synthetic-based biomaterial products for use in spine surgery, the repair of fractures and a broad range of clinical needs in the trauma, joint reconstruction, revision and extremities markets. We also market products which complement our
biomaterials platforms.

Our near-term commercial business is based on our VITOSS® Bone Graft Substitute technology platforms, which are designed to address the non-structural bone graft market by offering synthetic alternatives to the use of autograft or cadaver-derived bone
material, and VITAGEL® Surgical Hemostat, which is an adherent matrix and an impermeable barrier to blood flow. Our longer-term U.S. clinical development program is focused on our
internally developed CORTOSS® Bone Augmentation Material technology platform, which is designed for injections into osteoporotic spines to treat vertebral compression fractures
(VCFs).

In addition, we employ in-house research and development in support of biomaterial and biologic technology platforms. We work jointly
with Kensey Nash Corporation (Kensey) to develop and commercialize synthetic-based biomaterial products, and we market VITAGEL under a license with Angiotech Pharmaceuticals (U.S.) Inc., (Angiotech), and continue to pursue
similar relationships with other biomaterials companies.

In the U.S., we have assembled a field
sales network of direct sales representatives and independent non-stocking distributors in order to market VITOSS, VITAGEL, the IMBIBE® Bone Marrow Aspiration System and the CELLPAKER® Plasma Collection System. Outside of the U.S., we primarily utilize a network of independent stocking distributors to market VITOSS, CORTOSS, ALIQUOT® Delivery System, VITAGEL and CELLPAKER.

2. Summary of Significant Accounting Policies:

Preparation of Financial Statements and Use of Estimates

The preparation of
the consolidated financial statements requires us to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities as of the date of the consolidated
financial statements, and the reported amounts of revenues and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates, including, but not limited to, those related to accounts receivable and inventories. We use
authoritative pronouncements, historical experience and other assumptions as the basis for making estimates. Actual results could differ from those estimates.

Basis of Consolidation

The
consolidated financial statements include the accounts of Orthovita, Inc. and our wholly owned subsidiaries. We have eliminated all intercompany balances in consolidation.

Net Loss Per Common Share

We have presented net loss per common share pursuant to Statement of Financial Accounting
Standards (SFAS) No. 128, Earnings per Share. Basic net loss per share excludes securities exercisable for or convertible into shares of Common Stock, and is computed by dividing net loss applicable to common
shareholders by the weighted average number of shares of Common Stock outstanding for the period. Diluted net loss per common share data is computed assuming the conversion or exercise of all dilutive securities such as Preferred Stock and Common
Stock options and warrants. As of December 31, 2007, 2006 and 2005, no shares of Preferred Stock were outstanding.

Common Stock options and warrants
exercisable to purchase 8,022,051, 9,124,280, and 8,671,183 shares were excluded from our computation of diluted net loss per common share for the years ended December 31, 2007, 2006 and 2005, respectively, because the inclusion of the shares
in the calculation would have been anti-dilutive due to our losses.

Revenue Recognition

Revenue is not recognized until persuasive evidence of an arrangement exists, performance has occurred, the sales price is fixed or determinable and collection is probable. In the U.S., product sales revenue is
recognized upon either receipt of documentation from the customer indicating their consumption of product from consigned inventory or shipment of purchased product to the customer. Outside the U.S., revenue from product sales is primarily recognized
upon receipt of our product by our independent stocking distributors. Outside the U.S., we do not allow product returns or exchanges. We have no obligations to our customers once title has been transferred. Both our U.S. customers and our
independent stocking distributor customers outside of the U.S. are generally required to pay on a net 30-day basis, and payment discounts are not offered.

Allowance for Doubtful Accounts

We maintain an accounts receivable allowance for an estimated amount of losses that may result from a
customers failure to pay for product purchased. We analyze accounts receivable and historical bad debts, customer concentrations and changes in customer payment patterns when evaluating the adequacy of the allowance for doubtful accounts. If
the financial condition of our customers were to deteriorate resulting in an impairment of their ability to make payments, additional allowances may be required.

Inventory

Inventory is stated at the lower of cost or market value using the first-in first-out basis, or FIFO.

##### Table of Contents

A provision is recorded to reduce the cost of inventories to the estimated net realizable values, if required. In accordance with SFAS No. 2,
Accounting for Research and Development Costs the costs of producing inventory in the reporting periods prior to the receipt of regulatory approval or clearance are recorded as research and development expense.

Property and equipment

Property and equipment, including assets held under
capitalized lease obligations, are recorded at cost. Depreciation is calculated on a straight-line basis over the estimated useful life of each asset, generally three to five years. The useful life for leasehold improvements is generally the
remaining term of the facility lease. Expenditures for major renewals and improvements are capitalized, and expenditures for maintenance and repairs are charged to operations as incurred.

Revenue Interest Obligation

During October 2001, we completed a $10,000,000
product development and equity financing with Paul Capital Royalty Acquisition Fund, L.P., which was subsequently assigned to Royalty Securitization Trust I (Royalty Trust) (see Note 7). In March 2002, we amended the original financing,
which resulted in a one time increase to the revenue interest obligation of $1,945,593, increasing the balance of the revenue interest obligation to $7,167,700. The revenue interest obligation is accounted for in accordance with Emerging Issues Task
Force Issues (EITF) No. 88-18, Sales of Future Revenues. On July 30, 2007, we repurchased the revenue interest obligation from Royalty Trust. As a result, we are no longer obligated to pay royalties on our
products subject to the revenue interest obligation, including VITOSS and CORTOSS. The repurchase price for the revenue interest obligation consisted of a payment of $20,000,000 in cash and 1,136,364 shares of our common stock valued at $3.32 per
share, which was the market price per share on the date of the transaction. As a result of the repurchase, we recorded a charge of $16,605,029 during the year ended December 31, 2007 to account for the difference between the repurchase price
valued at $23,772,729 and the $7,167,700 carrying value of the revenue interest liability on our Consolidated Balance Sheet as of the date of the transaction. In connection with the repurchase, Royalty Trust assigned to us all of its interest under
the agreements relating to the revenue interest obligation, effectively terminating the security interest in certain of our assets and the pledge of stock of our wholly-owned subsidiary that we had granted Royalty Trust to secure our obligations
under the revenue interest agreement.

The products that were subject to the revenue interest have only been approved or cleared and marketed for the past
several years or are still under development. For these reasons, as of July 29, 2007, we could not make a reasonable estimate of future revenues and payments that could have become due to Royalty Trust under this financing. Accordingly, we did
not amortize any portion of the liability attributable to the revenue interest obligation, and we charged revenue interest expense in accordance with EITF No. 88-18 for the revenue interest due to Royalty Trust as revenues subject to the
revenue interest obligation were recognized (see Note 7). Revenue interest expense of $756,703, $1,179,466 and $989,287 has been recorded for the years ended December 31, 2007, 2006 and 2005, respectively.

Income Taxes

We account for
income taxes in accordance with an asset and liability approach requiring the recognition of deferred tax assets and liabilities for the expected tax consequences of events that have been recognized in the financial statements or tax returns.
Deferred tax assets and liabilities are recorded without consideration as to their ability to be realized. The deferred tax asset includes net operating loss and credit carryforwards, and the cumulative temporary differences related to certain
research and patent costs, which have been charged to expense in our consolidated statements of operations but have been recorded as assets for tax return purposes. These tax assets are amortized over periods generally ranging from 10 to 17 years
for tax purposes. The portion of any deferred tax asset, for which it is more likely than not that a tax benefit will not be realized, must then be offset by recording a valuation allowance against the asset.

Accounting for Stock Options Issued to Employees

In December 2004, the
Financial Accounting Standards Board (FASB) issued SFAS No. 123R, Share-Based Payment (SFAS No. 123R). This statement revised SFAS No. 123, Accounting for Stock-Based Compensation
(SFAS No. 123), and required companies to expense the value of employee stock options and similar awards. We adopted SFAS No. 123R effective January 1, 2006 using the modified prospective transition method, as permitted by
SFAS No. 123R, and therefore have not restated our financial results for prior periods. Under this transition method, stock-based compensation expense for the year ended December 31, 2006 includes the remaining compensation expense for all
stock-based compensation awards granted prior to, but not yet vested as of, January 1, 2006 based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123. These amounts are being amortized based
upon a graded vesting schedule in accordance with FASB Interpretation No. (FIN) 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans. Stock-based compensation expense for all stock-based
compensation awards granted to employees subsequent to January 1, 2006 is based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123R and amortized on a straight-line basis over the requisite service
period of the award.

The following table sets forth the total stock-based compensation expense resulting from the adoption of SFAS No. 123R included
in our Consolidated Statements of Operations for the years ended December 31, 2007 and 2006.

Prior to the adoption of SFAS No. 123R, we applied the intrinsic-value based method of accounting prescribed
by Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB No. 25), and related interpretations to account for our stock option

plans. Under this method, compensation expense was computed and recorded on the date of grant for the intrinsic value related to stock options granted,
reflected by the difference between the option exercise price and the fair market value of the underlying shares of Common Stock on the date of grant. Accordingly, because the exercise price of our employee stock options equaled the market price of
the underlying stock on the date of grant, no compensation expense was recognized.

The following table presents the pro forma compensation cost for our
awards had they been recognized under SFAS No. 123.

|Expected life           |  | 5 years                 |   |  | 5 years |   |  | 6 years |  

The weighted average fair value of options granted in 2007, 2006 and 2005 was $1.61, $2.02 and $2.70,
respectively.

For the years ended December 31, 2007, 2006 and 2005, we calculated historical volatility based upon the daily closing prices of our
Common Stock as quoted on the Nasdaq Global Market (Nasdaq) or Nasdaq Europe (for closing prices prior to August 2, 2000, our date of listing on Nasdaq), over a prior period having a term equal to the expected life of the stock
options. The change in historical volatility for the year ended December 31, 2006 from 2005 was primarily due to a decrease in the expected life of the options from six years for the years ended December 31, 2005 to five years for the year
ended December 31, 2006.

##### Table of Contents

The Companys Board of Directors approved the acceleration of vesting for all out-of-the-money unvested
stock options held by current employees, officers or directors on November 29, 2005 under the Companys 1993 Stock Option Plan and Amended and Restated 1997 Equity Compensation Plan. An option was considered out-of-the-money if
the stated exercise price was greater than $3.50 per share, the closing sale price of the Companys Common Stock on November 29, 2005. As a result of this action, vesting of options to purchase approximately 1,110,000 shares of our Common
Stock was accelerated. The decision to accelerate the vesting of these options was made primarily to reduce compensation expense that might be recorded in future periods following our adoption of SFAS No. 123R. The pro forma table above for the
year ended December 31, 2005 includes this 2005 acceleration. If vesting of options had not been accelerated, the expense related to these options would have been as follows: $1,600,000 in 2006, $1,400,000 in 2007, $1,200,000 in 2008 and
$800,000 in 2009.

The pro forma compensation charge presented above may not be representative of that to be expected in the future years to the extent
that additional stock options are granted and the fair value of the common stock increases or decreases.

Research & Development Costs

In accordance with SFAS No. 2 Accounting for Research and Development Costs, we expense all research and development
expenses as incurred.

Foreign Currency Translation

The functional currency for the Companys branch operation in Europe is the Euro. In accordance with SFAS No. 52, Foreign Currency Translation, assets and liabilities related to this foreign operation are
translated at the current exchange rates at the end of each period. Revenues and expenses are translated at average exchange rates in effect during the period. The resulting translation adjustments are accumulated as a separate component of
shareholders equity (accumulated other comprehensive income). Foreign currency transaction gains and losses, if any, are included in results of operations.

Supplemental Cash Flow Information

During 2007, we issued five-year warrants to purchase 1,466,276 shares of our common stock at an exercise price
of $3.41 per share in connection with entering into a senior secured note purchase facility and issuing a note thereunder. Of these warrants, warrants to purchase 733,138 shares are currently exercisable. The unexercisable warrants shall become
exercisable ratably upon future issuances of notes under the facility.

During 2007, 2006 and 2005, respectively, we issued options and/or warrants for the
purchase of 0, 40,000 and 48,398 shares of Common Stock with various exercise prices to certain vendors in consideration for services valued at $0, $125,357 and $146,313, respectively. We recorded a non-cash adjustment in 2007 and 2006 for the
change in fair market value of our fully-vested non-employee consultant stock options outstanding. See Note 3.

During 2007, we exchanged 614,063 non
employee stock options for shares of our common stock. We recorded a non-cash charge of $1,160,725 for the year ended December 31, 2007 as a result of these exchanges.

In 2005, we issued 9,667 shares of Common Stock, respectively, valued at $38,093, pursuant to a

clinical assessment agreement.

During the years ended
December 31, 2007, 2006 and 2005, we made restricted stock awards of 36,204, 24,192 and 20,928 shares to our non-employee directors in consideration of their services. The awards were valued at $104,992, $85,160 and $89,991 for the years ended
December 31, 2007, 2006 and 2005, respectively, and are subject to certain vesting provisions.

In 2007 and 2006, we incurred capital lease
obligations of $12,610 and $322,469, respectively.

In 2007, 2006 and 2005, cash paid for interest expense and revenue interest expense aggregated
$1,358,934, $1,424,958 and $1,074,197, respectively.

Recent Accounting Pronouncements

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities  Including an amendment of FASB Statement No. 115 (SFAS
No. 159), which allows companies to choose, at specific election dates, to measure eligible financial assets and liabilities at fair value that are not otherwise required to be measured at fair value. If a company elects the fair value option
for an eligible item, changes in that items fair value in subsequent reporting periods must be recognized in current earnings. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating
the impact of SFAS No. 159 on our consolidated financial statements and related disclosures.

In September 2006, the FASB issued SFAS No. 157,
Fair Value Measurements (SFAS No. 157), which is applicable for fiscal years beginning after November 15, 2007. SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted
accounting principles and expands disclosures about fair value measurements. SFAS No. 157 applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting
pronouncements that fair value is the relevant measurement attribute. Although SFAS No. 157 does not require any new fair value measurements, its application may, for some entities, change current practices related to the definition of fair
value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. We are currently evaluating the impact of the adoption of SFAS No. 157 on our consolidated financial statements and related disclosures.

Reclassifications

reclassified to conform to the 2007 presentation.

3. Accounting for Derivative Liability Associated With Non-Employee Stock Options:

Accounting for Stock Options Issued to Non-employees

During the year ended
December 31, 2006, we granted options for the purchase of an aggregate of 25,000 shares of Common Stock with various exercise prices to certain consultants in consideration for services. The $80,403 aggregate grant date fair value of

these options for 2006, was included in selling and marketing expenses in our Consolidated Statements of Operations during the applicable period.
Additionally, during the years ended December 31, 2006, we granted options for the purchase of an aggregate of 15,000 shares of Common Stock with various exercise prices to certain consultants in consideration for research and development
services. The $44,954 aggregate grant date value of these options was included in research and development expenses in our Consolidated Statements of Operations during 2006. These stock options were for services rendered, were fully vested on the
date of grant and were valued using the Black-Scholes model on the respective dates of their grant.

Historically, the common stock purchase options we
have granted to non-employee consultants as compensation for services rendered were fully vested on the date of the grant. Upon adoption of SFAS No. 123R, during the service and vesting period, these options are accounted for under SFAS
No. 123R. However, once the service period terminates, these options are then accounted for in accordance with EITF No. 00-19, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in a Companys Own
Stock, from the date the service/vesting period terminates through the expiration of the option or until it is exercised, whichever is earlier. In certain circumstances, these awards may have to be settled in cash. Accordingly, effective
January 1, 2006, we reclassified from equity to liabilities the aggregate fair value of our fully-vested non-employee consultant stock options that were outstanding as of January 1, 2006. In addition, we are required to record a fair value
adjustment at the end of each quarter for the change in the fair value of our fully-vested non-employee consultant stock options outstanding.

The
following table sets forth the change in fair value of our fully vested non-employee consultant stock options outstanding included in our Consolidated Statements of Operations for the years ended December 31, 2007 and 2006. The change in fair
value was recorded as a reduction in expenses for the years ended December 31, 2007 and 2006 as indicated below.

Our stock price may be volatile and may fluctuate. Since we cannot determine what our stock price will be at the
end of future quarters, we cannot estimate the impact of EITF No. 00-19 on our Consolidated Balance Sheet and Consolidated Statements of Operations in the future. An increase to our stock price as of the last day of a given quarter, as compared to
our stock price as of the last day of the prior quarter, may result in an increase to the liability recorded to our Consolidated Balance Sheet and an increase to operating expenses recorded in our Consolidated Statements of Operations. Conversely, a
decrease to our stock price as of the last day of a given quarter, as compared to our stock price as of the last day of the prior quarter, may have the opposite effect. Additionally, any subsequent changes to the assumptions used in the
Black-Scholes model to estimate the fair value of these non-employee consultant options will impact the effect of EITF No. 00-19 on our Consolidated Balance Sheet and Consolidated Results of

On January 1, 2006, we recorded the fair
value of our outstanding non-employee consultant stock options as a reduction to additional paid in capital and an increase to our derivative liability in the amount of $2,267,086. The table below summarizes the changes in our derivative liability
associated with non-employee consultant stock options for the period from January 1, 2006 through December 31, 2007.

The fair value of our derivative liability associated with non-employee consultant stock options was estimated
using the Black-Scholes option pricing model. The weighted average fair value of our non-employee consultant stock options outstanding was $1.59 and $2.02, which was based on the closing price of our stock as quoted on Nasdaq on December 31,
2007 and 2006, which was $3.49 and $3.63 per share, respectively, and the following weighted average assumptions as of December 31, 2007 and 2006:

During the year ended December 31, 2007 we exchanged options to purchase 614,063 shares of our common stock
for 614,063 common shares for our non-employee consultants. In connection with this exchange, we incurred a non-cash charge of $1,160,724. The value of the non-employee consultant stock options was $782,060 and the value of the common stock issued
was $1,942,784.

As of December 31, 2007, our non-employee consultants held fully-vested stock options to purchase 205,473 shares of our Common Stock,
at an average exercise price of $3.20 per share and an average remaining term of approximately five years. We have classified this liability as non-current as management does not believe that it will need to be satisfied using current assets within
the next twelve months.

We invest excess cash in highly liquid investment-grade marketable securities including

corporate commercial paper and U.S. government agency bonds. For financial reporting purposes, we consider all highly liquid investment instruments purchased
with an original maturity of three months or less to be cash equivalents. Investments are considered available-for-sale and, accordingly, unrealized gains and losses are included as a separate component of shareholders equity. As of
December 31, 2007 and 2006, cash, cash equivalents and investments consisted of the following:

Amortization of discounts and premiums related to investments resulted in income of $832,214 and $119,197 recorded
for the year ended December 31, 2007 and 2006, respectively. Amortization of discounts and premiums related to investments resulted in expense of $235,981 for the year ended December 31, 2005.

Total assets under capital lease were $0 and $430,451 with related accumulated amortization of $0 and $53,525 at
December 31, 2007 and 2006, respectively (see Note 8). Depreciation expense for the years ended December 31, 2007, 2006 and 2005 was $1,588,823, $1,566,517 and $1,279,335, respectively.

7. Revenue Interest Obligation:

During October 2001, we completed a
$10,000,000 product development and equity financing with Paul Capital Royalty Acquisition Fund, L.P., which was subsequently assigned to Royalty Securitization Trust I (Royalty Trust), which provided for the payment of revenue interest
to Royalty Trust. The net proceeds from the financing were first allocated to the fair value of the Common Stock on the date of the transaction (which was $4,777,893), and the $5,222,107 remainder of the net proceeds was allocated to the revenue
interest obligation in accordance with Emerging Issues Task Force Issues No. 88-18, Sales of Future Revenues (EITF 88-18). On March 22, 2002, we amended the original financing, which resulted in a one-time
increase to the revenue interest obligation of $1,945,593, increasing the balance of the revenue interest obligation to $7,167,700. On July 30, 2007, we repurchased the revenue interest obligation from Royalty Trust. As a result, we are no
longer obligated to pay royalties on our products subject to the revenue interest obligation, including VITOSS and CORTOSS. The repurchase price for the revenue interest obligation consisted of a payment of $20,000,000 in cash and 1,136,364 shares
of our common stock valued at $3.32 per share, which was the market price per share on the date of the transaction. As a result of the repurchase, we recorded a charge of $16,605,029 during the year ended December 31, 2007 to account for the
difference between the repurchase price valued at $23,772,729 and the $7,167,700 carrying value of the revenue interest liability on our Consolidated Balance Sheet as of the date of the transaction. In connection with the repurchase, Royalty Trust
assigned to us all of its interest under the agreements relating to the revenue interest obligation, effectively terminating the security interest in certain of our assets and the pledge of stock of our wholly-owned subsidiary that we had granted
Royalty Trust to secure our obligations under the revenue interest agreement.

The revenue interest agreement provided for Royalty Trust to receive 3.5% on
the first $100,000,000 of annual sales, reducing to 1.75% of annual sales in excess of $100,000,000, of certain of our products, including VITOSS, CORTOSS and any structural bioactive device, in North America and Europe through 2016, subject to
certain adjustments. This revenue interest percentage was subject to increase to a maximum of 4.375% on that portion of product sales that specifically relates to VITOSS and CORTOSS, if we failed to meet contractually specified levels of annual net
sales of products for which Royalty Trust is entitled to receive its revenue interest. Since we failed to meet the specified annual net sales levels, Royalty Trust received 4.375% on that portion of product sales that specifically related to VITOSS
and CORTOSS during 2006, 2005 and 2004.

Throughout the term of the Royalty Trust revenue interest agreement, we were required to make advance payments on
the revenue interest obligation at the beginning of each year. In February 2005, the revenue interest agreement with Royalty Trust was amended by mutual agreement to reduce the advance payment for 2005 from $3,000,000 to $1,600,000. Of the
$1,600,000 paid to

##### Table of Contents

Royalty Trust in 2005, $989,287 was earned in 2005 and the balance of $610,713 was repaid to us in April 2006. In December 2005, the revenue interest
agreement with Royalty Trust was again amended by mutual agreement to reduce the advance payment for 2006 from $3,000,000 to $1,750,000, which was paid to Royalty Trust during January 2006. Of the $1,750,000, $1,179,466 was earned in 2006 and the
balance of $570,534 was repaid to us in January 2007. In March 2007, the revenue interest agreement with Royalty Trust was further amended by mutual agreement to reduce the advance payment for 2007 from $3,000,000 to $1,750,000. As a result, in
March 2007, Royalty Trust returned to us $1,250,000 of the $3,000,000 advance payment for 2007 that we had previously paid Royalty Trust in January 2007. As a result of our repurchase of the revenue interest from Royalty Trust on July 30, 2007,
Royalty Trust retained $756,703 of the 2007 advance payment for revenue interest owed to Royalty Trust as of the repurchase date, and returned the $993,297 balance to us.

The products that were subject to the revenue interest agreement have been approved and launched at various times over the last several years or are still under development. For these reasons, as of December 31,
2006, we could not make a reasonable estimate of future revenues and payments that could become due to Royalty Trust under this financing. Accordingly, we did not amortize any portion of the liability attributable to the revenue interest obligation,
and we charged revenue interest expense in accordance with EITF No. 88-18 for the revenue interest due to Royalty Trust as revenues subject to the revenue interest obligation were recognized. Revenue interest expense of $756,703, $1,179,466 and
$989,287 was recorded for the years ended December 31, 2007, 2006 and 2005, respectively.

8. Notes Payable and Capital Lease Obligations:

Notes Payable

On July 30, 2007, we entered into a
$45,000,000 senior secured note purchase facility with LB I Group Inc., an affiliate of Lehman Brothers Inc. Notes issued under the facility are due July 30, 2012. We initially issued $25,000,000 of our 10% senior secured notes under the
facility and used most of the proceeds to repurchase a revenue interest obligation. Borrowings under the facility are guaranteed by us and one of our wholly-owned subsidiaries. The facility is also secured by a first priority lien on substantially
all of our assets, excluding those related to our CORTOSS and ALIQUOT products.

Additionally, we issued five-year warrants to purchase 1,466,276 shares of
our common stock at an exercise price of $3.41 per share in connection with entering into a senior secured note purchase facility and issuing a note thereunder. Of these, warrants to purchase 733,138 shares are currently exercisable. The
unexercisable warrants shall become exercisable ratably upon future issuances of notes under the facility. The fair market value of the warrants issued in connection with the debt facility was $1,206,400, which was recorded as a debt discount at the
date of the transaction. The Company is amortizing the value of the warrants over the five-year term of the note. Interest expense related to the amortization of the debt discount was $101,776 for 2007. The carrying value of the note was $23,895,376
at December 31, 2007.

Under the facility, we must comply with various financial and non-financial covenants. For example, we are required to maintain a
minimum cash balance equal to at least 25% of the then outstanding principal amount under the notes in a separate account that is pledged as collateral for the loan. As of December 31, 2007, we must maintain a minimum cash balance of
$6,250,000. The primary non-financial covenants limit our ability to incur indebtedness or liens, sell assets, conduct mergers or acquisitions, make investments and pay dividends.

During 2006 and 2005, we granted stock options to certain consultants in consideration for various services (see
Accounting for Derivative Liability Associated with Non-Employee Stock Options, above in Note 3).

Employee Stock Purchase Plan

In November 1998, an Employee Stock Purchase Plan (the ESPP) was established to provide eligible employees an opportunity to purchase our Common Stock. Under
the terms of the ESPP, eligible employees may have up to 10% of eligible compensation deducted from their pay to purchase Common Stock. Through December 31, 2005, the per share purchase price was 85% of the lower closing price on the first or
last trading day of each calendar quarter. However, effective January 1, 2006, the per share purchase price is 95% of the closing price on the last trading day of each calendar quarter. The amount that may be offered pursuant to the ESPP is
300,000 shares of our Common Stock. There were 42,394, 28,061 and 26,959 shares purchased under the ESPP during 2007, 2006 and 2005, respectively, for cash proceeds of $125,055, $102,253 and $86,812, respectively. As of December 31, 2007, there
were 93,706 shares of Common Stock available for purchase under the ESPP.

Common Stock Purchase Warrants

On July 30, 2007, we issued five-year warrants to purchase 1,466,276 shares of our common stock at an exercise price of $3.41 per share in connection with entering
into a senior secured note purchase facility (See Note 8). Of these, warrants to purchase 733,138 shares are currently exercisable. The unexercisable warrants shall become exercisable ratably upon future issuances of notes under the facility.

2007, as compared to approximately 17% and 9% of our product sales during the year ended December 31, 2006 and 2005, respectively.

13. Income
Taxes:

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized
in income in the period that includes the enactment date.

The asset and liability method requires that deferred tax assets and liabilities be recorded
without consideration as to their realizability. The portion of any deferred tax asset for which it is more likely than not that a tax benefit will not be realized must then be offset by recording a valuation allowance. A valuation allowance has
been established against all of our deferred tax assets, with the exception of the Texas margin tax credit, as it is we have determined not more likely than not to be realized given our history of operating losses. The deferred tax asset primarily
includes net operating loss and tax credit carryforwards, accrued expenses not currently deductible and the cumulative temporary differences related to certain research and patent costs, which have been charged to expense in the accompanying
Statements of Operations but have been recorded as assets for income tax purposes.

On May 18, 2006, the Texas Governor signed into law a Texas margin tax which restructures the state business tax
by replacing the taxable capital components of the current franchise tax with a new taxable margin component. The Texas margin tax is effective for taxable years ended on or after January 1, 2007. As a result of the Texas margin
tax we recognized current state income tax expense of $35,000 and a deferred state income tax benefit of $302,980 for the Texas temporary credit on taxable margin. Under the Texas Margin Tax enacted statute, we have the right to claim a temporary
credit against our Texas Margin Tax liability over a 20 year period. As a result, we have recorded a deferred tax asset of $302,980 which is included in Other Assets on our Consolidated Balance Sheet. We have recognized a deferred tax asset related
to the Texas tax credit as we believe it will more likely than not to be realized based on projections of future Texas Margin Tax liabilities.

As of
December 31, 2007, we had approximately $111,100,000 of federal net operating loss carryforwards, $100,350,000 of state net operating loss carryforwards and $12,100,000 of foreign net operating loss carryforwards. Federal net operating loss
carryforwards begin to expire in 2009 while the state net operating carryforwards have begun to expire. The foreign net losses have an unlimited carryforward period. The amount of U.S. federal net operating loss and credit carryforwards which can be
utilized in any one period may be limited by federal and state income tax regulations, since a change in ownership as defined in Section 382 and 383 of the Internal Revenue Code may have occurred in prior years. The amount of net operating loss
carryforwards which can be utilized in any one period on the Pennsylvania corporate income tax return is limited to the greater of $3,000,000, or 12.5%, of apportioned net taxable income beginning in 2007. Federal and Pennsylvania research and
development tax credits of $1,248,488 and $220,630 begin to expire in 2010 and 2014, respectively. The Texas Margin Tax temporary credit of $302,980 has a carryforward period of 20 years.

##### Table of Contents

We lease office space and equipment under non-cancelable operating leases. We entered into two leases in January, 2008
for space located in the Great Valley Corporate Center in Malvern, Pennsylvania. We entered into a lease for approximately 30,900 square feet of unfinished space for a new warehouse space. The initial term of this lease is 55 months commencing
January 1, 2008, and the initial annual base rent under the lease is approximately $216,125. In January, 2008, we entered into a lease for approximately 4,800 square feet of additional office and laboratory space. The initial term of this lease
is 55 months commencing January 1, 2008, and the initial annual base rent under the lease is approximately $43,593. In April 2007, we entered into a 63-month lease for additional office space which commenced effective May 1, 2007 and
terminates July 2012. For the years ended December 31, 2007, 2006 and 2005, lease expense was $689,826, $563,810 and $439,742, respectively. At December 31, 2007, future minimum rental payments under operating leases are as follows:

Revenue Interest Obligation (see Note 7)

Agreement with Kensey Nash Corporation

In March 2003, we entered into an agreement with Kensey to jointly develop and
commercialize certain biomaterials-based products based upon our VITOSS platform. The new products to be developed under this agreement are based on our internally developed proprietary VITOSS bone void filler material in combination with
proprietary resorbable Kensey biomaterials. Kensey has the exclusive right to manufacture any approved or cleared jointly developed product under the agreement, and we will market and sell the product worldwide. This right extends until February
2014 for the VITOSS FOAM product platform. Following the regulatory approval or clearance of each new product under the agreement, we have obligations to pay Kensey for manufacturing the product and make royalty payments to Kensey based on the net
sales of such product. In December 2003, we received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for the first jointly developed product platform, VITOSS FOAM, and we commenced sales on the first of several product
configurations under the VITOSS FOAM product platform during February 2004.

During the years ended December 31, 2007, 2006 and 2005, we purchased
$8,194,360, $3,624,662 and $4,808,552, respectively, of product inventory manufactured by Kensey on our behalf. As of December 31, 2007 and December 31, 2006, we owed Kensey $2,569,004 and $1,277,886, respectively, for manufactured product
inventory and royalties, which are included in accounts payable and other accrued expenses on the Consolidated Balance Sheets. All product royalty expense payable to Kensey is included in cost of sales on our Consolidated Statements of Operations as
we recognize product sales revenue from our customers.

In addition, we pay royalties to Kensey on our VITOSS Bone Graft Substitute product sales, based on a royalty arrangement
that Kensey purchased from the products co-inventor effective April 2004, up to an aggregate payment of $5,000,000. From inception of the royalty arrangement through December 31, 2007, we have made aggregate royalty payments of
approximately $2,000,000.

Agreement with Allergan

In
November 2007, we entered into a supply and license agreement to acquire raw material, equipment and a technology license from Allergan, Inc. and its affiliate Allergan Sales, LLC for an aggregate purchase price of approximately $6,600,000 in cash.
We expect to close the transaction and make the purchase price payment in a lump sum on or about October 31, 2008.

The raw material, equipment and
license to be acquired from Allergan relate primarily to the production of our VITAGEL product. Under the agreement, Allergan will manufacture and supply specified quantities of collagen to us no later than October 31, 2008. We will also
purchase no later than the fourth quarter of 2008 certain collagen production and test equipment from Allergan under the agreement. Additionally, Allergan will grant us a non-exclusive, perpetual, royalty-free, irrevocable license to certain
collagen production process technology and know-how.

15. Agreements with Angiotech Pharmaceuticals, Inc.

In June 2004, we entered into a Distribution Agreement with Angiotech to distribute to surgical customers
throughout North America the CoStasis® composite liquid hemostat (which we re-branded as VITAGEL Surgical Hemostat) and the CELLPAKER® plasma collection system used in conjunction with VITAGEL. The Distribution Agreement required us to purchase the products and make royalty payments to Angiotech based on the net sales of such products. Effective September 30, 2005, the
Distribution Agreement was amended to provide for the transition of product and accessory manufacturing responsibility from Angiotech to us. The amendment also changed the royalty rate payable by us to Angiotech and modified the method for
calculating net sales of such products. Angiotech decided to cease the manufacture of VITAGEL and CELLPAKER by November 2005; therefore, in October 2005, we purchased all available existing VITAGEL and CELLPAKER products, accessories and
work-in-process from Angiotech for $1,800,000. On June 16, 2006, we obtained pre-market approval (PMA) from the FDA to sell VITAGEL manufactured at our Malvern, Pennsylvania facility (the VITAGEL PMA). After receiving
the VITAGEL PMA, we started manufacturing VITAGEL in July 2006, and in August 2006 we commenced selling VITAGEL first manufactured since obtaining the VITAGEL PMA. In addition, we had previously manufactured under the VITAGEL PMA three lots of
VITAGEL that became available for sale in late June 2006. In January 2007, we obtained approval from the FDA for a PMA supplement which enables us to sell CELLPAKER manufactured by our subcontractors facility. Effective January 1, 2006,
we entered into a License Agreement with Angiotech pursuant to which Angiotech licensed VITAGEL products and the CELLPAKER plasma collection system to us and we assumed manufacturing

responsibility for these products. The Distribution Agreement described above served as the basis for the establishment of the License Agreement. In
accordance with its terms, the Distribution Agreement terminated in the first quarter of 2007 upon completion of the sale of all VITAGEL and CELLPAKER inventory products that we purchased from Angiotech in October 2005. Until December 29, 2006,
we paid royalties on sales of the VITAGEL and CELLPAKER inventory that we purchased from Angiotech in October 2005 in accordance with the terms of the Distribution Agreement.

On December 29, 2006, pursuant to a Royalty Sale Agreement with Angiotech, we purchased the profit-sharing royalty rights for VITAGEL and CELLPAKER products under the License Agreement for $9,000,000 in cash.
Concurrently with such purchase, we entered into an Amended and Restated License Agreement with Angiotech that amended the original License Agreement to eliminate our obligations to meet minimum sales requirements, extend the term of the license
from December 31, 2014 through July 31, 2017, and eliminate certain termination rights in favor of Angiotech. Under the Amended and Restated License Agreement, we have exclusive rights to manufacture and sell VITAGEL products throughout
the world for orthopedic indications, and non-exclusive rights to manufacture and sell CELLPAKER products throughout the world for all indications. Under the Amended and Restated License Agreement, Angiotech has an option for co-exclusive rights
outside the orthopedic field which, if exercised, would permit Angiotech to manufacture and sell an Angiotech-branded VITAGEL product throughout the world. Until Angiotech elects to exercise its option for co-exclusive rights, we have exclusive
rights to manufacture and sell VITAGEL outside of the orthopedic field throughout the world. If Angiotech elects to exercise its option, we would then have co-exclusive rights to manufacture and sell VITAGEL outside of the orthopedic field
throughout the world. Prior to the amendment and restatement of the License Agreement on December 29, 2006, we were required to make royalty payments thereunder based on a share of all revenue we received from net sales of VITAGEL and CELLPAKER
products that we manufactured. The $9,000,000 payment has been recorded as a License Right Intangible on the accompanying Consolidated Balance Sheet as of December 31, 2006. This amount is being amortized based upon the greater of
(a) straight-line amortization through July 31, 2017, or (b) actual units sold in a given period in relation to the total estimated units to be sold over the expected life of the applicable patent, which is July 31, 2017.

During the years ended December 31, 2006 and 2005, we purchased $64,944 and $3,227,199, respectively, of product inventory from Angiotech, and as of
December 31, 2006, we owed Angiotech $52,783 for manufactured product inventory and royalties, which is included in accounts payable and other accrued expenses on the consolidated balance sheet. Amortization of $850,392 was recorded during the
year ended December 31, 2007 and is included in cost of sales on the accompanying consolidated statements of operation.
