PART I



|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 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-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., which is a 9.3% shareholder of the Company, 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 wholly-owned subsidiaries
incorporated in Delaware to hold our intangible properties and certain cash funds.

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 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.

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. 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. We anticipate recording an annual non-cash expense of at
least $850,000 in 2007 and in each year thereafter through July 31, 2017 for amortization of the

$9,000,000 royalty prepayment. 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.

BioMimetic Agreement

In August 2002, we entered into a supply agreement with
BioMimetic Pharmaceutical Inc. (BioMimetic) 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.

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 sales agencies that we began to assemble in June 2003. As of December 31, 2006, we had approximately 74 direct sales representatives and arrangements with approximately 22 independent sales
agencies 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 sales agency 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).

Information regarding our product sales by geographic markets for the years ended December 31, 2006, 2005 and 2004 are included in Note 12 (Product Sales) to the
consolidated financial statements, which is included elsewhere in our report on Form 10-K.

VITOSS is an ultra-porous resorbable beta-tricalcium phosphate bone void filler used to help the 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 over 180,000 units through December 31, 2006. 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 and the 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 also launched VITOSS Cancellous Chips during the first half of 2006.

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



7

##### Table of Contents

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. 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 that allows BioMimetic to use its rhPDGF in
combination with our



8

##### Table of Contents

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 rhPDGF. BioMimetic markets the combined product in the dental, periodontal, oral and cranio-maxillofacial bone
grafting markets.

The disposable IMBIBE devices provide spine and orthopedic surgeons with a simple method for harvesting a
patients own bone marrow, mixing it with VITOSS, and delivering the mixture to the bone graft site. We believe IMBIBE, when used together with VITOSS, will provide greater flexibility and options for surgeons. IMBIBE is covered by a U.S.
issued patent.

VITAGEL is an FDA-approved, 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

##### Table of Contents

rebranded CoStasis as VITAGEL Surgical Hemostat in January 2005 with CELLPAKER accessories, and relaunched the product 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. 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 aseptically 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 over 7,400 units of CORTOSS through December 31, 2006. 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. We expect that the two pilot studies will be
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 control 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 intervals up to 24 months post-procedure. If the study data is
supportive, we plan to seek FDA clearance for CORTOSS in the U.S. through the 510(k) regulatory process (see GOVERNMENT REGULATION below). We do not expect to receive FDA clearance for the sale of CORTOSS in the U.S. prior to 2008, if at all.

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 more natural elasticity and its ability to be mixed on demand. In addition, unlike PMMA, CORTOSS does not release volatile free unreacted monomers
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.

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,



11

##### Table of Contents

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 ALIQUOT. 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. ALIQUOT is covered by issued and pending U.S. and foreign patents.

SIGNIFICANT
CONTRACTUAL OBLIGATIONS

See Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operation,
included in this report for a discussion of significant contractual arrangements relating to (i) our joint product development and commercialization arrangements, (ii) our licensing arrangements and (iii) our revenue sharing
arrangement.

OUR RESEARCH & DEVELOPMENT

We
employ composite engineering, polymer science, biologics processing, solution chemistry and nanoparticulate ceramic glass science to create our bio-surgery materials technology platforms. We then utilize biomaterials and biologic technologies
developed, co-developed or licensed by us to commercialize bio-surgery products for spine and orthopedic surgical applications. Patents have been issued and additional patent applications have been filed to protect our key biomaterial developments.
See Patents and Proprietary Intellectual Property below for additional information. We incurred approximately $8,472,000, $7,167,000 and $5,657,000 in research and development expenses in 2006, 2005 and 2004, respectively.

PATENTS AND PROPRIETARY INTELLECTUAL PROPERTY

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, the products we have developed and marketed are covered by one or more of our eighteen issued U.S. patents, nineteen 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 patents are set to expire between 2015 and 2021; however,

##### Table of Contents

certain of our patents may be extendable under 35 United States Code 156, which pertains to the extension of the patent term.

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.

Our 24,800 square foot VITOSS, VITAGEL and CORTOSS 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. The most recent FDA inspection in June 2006 resulted in no FDA Form 483 observations cited.

We believe our existing manufacturing facilities have the capacity to meet our commercial needs into 2008. 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 the manufacturing facilities expansion by the end of 2007. We currently manufacture VITOSS, VITAGEL and CORTOSS at our manufacturing facilities. We are manufacturing CELLPAKER, IMBIBE and ALIQUOT
through outside third-party contract manufacturers. Our VITOSS is converted to 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).

Our ability to manufacture
our products is dependent on a limited number of specialty suppliers of certain raw materials. We have a supply agreement which provides bovine collagen for the manufacture of VITAGEL. The initial term of the supply agreement expires in August 2008;
however, we received notice in the first quarter of 2007 from our supplier of its intent to cease production of bovine collagen between January 1, 2008 and June 30, 2008 and sell or close its collagen processing plant by December 31,
2008. We are seeking to obtain a strategic collagen reserve for VITAGEL and are exploring solutions to ensure long and short-term collagen supply. If we locate a new source of collagen for VITAGEL or otherwise modify its manufacturing process or raw
material components, we may need to obtain approval for such modification from the FDA in the form of a PMA supplement. See GOVERNMENT REGULATION  United States. We also have a supply agreement with Kensey for bovine collagen used
in our VITOSS FOAM product line. We do not have any other supply agreements for raw materials. The failure of a supplier to continue to provide us with these 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 these products. Moreover, our failure to continue to maintain strategic reserve supplies of each significant single-sourced
material used to manufacture VITOSS, CORTOSS and certain products that we may develop in the future may result in a breach of our material financing agreement with Royalty Securitization Trust I

(Royalty Trust and successor-in-interest to Paul Capital Royalty Acquisition Fund, L.P.), which is described below in Item 7. 
Managements Discussion and Analysis of Financial Condition and Results of Operation  Critical Accounting PoliciesRevenue Interest Obligation.

SALES AND MARKETING

In June 2003, we began to assemble a U.S. field sales network of direct sales representatives
and independent sales agencies 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 sales agency 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 ALIQUOT.

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,
total disc replacement devices (TDRs) 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. These TDRs could negatively impact the spinal fusion
market which could in turn adversely impact the use of VITOSS in spine grafting procedures. However, we believe that several factors mitigate against the broad use of TDRs, 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. 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

##### Table of Contents

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.

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. 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.

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. We expect that the two pilot



15

##### Table of Contents

studies will be 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 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 intervals of up to 24 months post-procedure. If data from the pivotal study is supportive, we intend to seek clearance to market CORTOSS in the
U.S. through a 510(k) submission. We do not expect to receive FDA clearance for the sale of CORTOSS in the U.S. prior to 2008, if at all.

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. 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



16



---

##### Table of Contents

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 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.

##### Table of Contents

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. Our most recent
FDA inspection in June 2006 resulted in no observations with no corrective actions being required. 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 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 TNO, The Netherlands Organization for Applied
Science Research, 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



19

##### Table of Contents

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 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



20

##### Table of Contents

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 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



21



---

##### Table of Contents

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

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 defended. There can be no assurance that other product liability claims will not be



22

##### Table of Contents

asserted against us in the future. Under certain of our agreements with our independent sales agencies, stocking 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, 2006, we had 198 full-time employees, with 96 employees at our Malvern, Pennsylvania headquarters, 94
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 jeopardized.

We are highly dependent
on successfully selling our products for which we have received regulatory approval or clearance. We do not expect to obtain regulatory approvals or clearances in the United States for any of our products under development, if obtained at all, prior
to 2008. To date, we have received regulatory clearance or approval to market VITOSS, CORTOSS and ALIQUOT for specified uses in the European Union, Australia and countries adhering to the regulatory standards of the European Union. We have also
received regulatory clearance or approval to market VITOSS, IMBIBE, and VITAGEL in the United States. 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 fund operations. In particular, if our CORTOSS
product is not cleared in the United States or does not become commercially successful, our long-term viability may be jeopardized.

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



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



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



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



| |  |  | our dependence on the continued publication of independent pre-clinical and clinical data
| | - |  | -----------------------------------------------------------------------------------------



23



---

##### Table of Contents

| | to support the use of our products;
| | -----------------------------------



| |  |  | our need to 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 must 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 the inability to become profitable.

If losses continue in the long term, it 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 stock. In July 2004, we raised approximately $24,000,000 in net proceeds from the sale
of 5,681,818 shares of our Common Stock to Angiotech. 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. We believe our existing cash, cash equivalents, and investments of $28,338,522 as of December 31, 2006
will be sufficient to meet our currently estimated operating and investing requirements at least into the second quarter of 2008. To date, we have not been profitable. We have incurred substantial operating losses since our inception and at
December 31, 2006, had an accumulated deficit of $136,037,774. 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; and
| | - |  | ------------------------------------------------------------------------



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

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



24



---

##### Table of Contents

products may never be commercially accepted or generate sufficient product sales to fund operations.

We expect to raise additional capital. If we are unable to raise additional capital in the future, our product development could be limited and our long term
viability may be threatened; however, if we raise additional capital, your percentage ownership as a shareholder of Orthovita will decrease and constraints could be placed on the operation of our business.

We plan to seek to obtain additional funds through equity or debt financings, or strategic alliances with third parties either alone or in combination with equity or
debt financing investments.

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 and defense of intellectual property rights;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | the failure to develop strategic alliances for the marketing of some of our products;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | 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;
| | - |  | -----------------------------------------------------------------



| |  |  | inability to meet our obligations under our revenue sharing agreement;
| | - |  | ----------------------------------------------------------------------



| |  |  | 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;
| | - |  | ----------------------------------------------------------



| |  |  | 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, although we have no present commitments or understandings to do so, 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.

##### Table of Contents

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 may suffer.

The manufacture of our products is subject to regulation and
periodic inspection by various regulatory bodies for compliance with current FDA Quality System Regulation and requirements, 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. These facilities are subject to inspection by the FDA for compliance with FDA device manufacture requirements. The most recent FDA inspection in June 2006 resulted in no FDA Form 483 observations cited. . Pursuant to our license
agreement with Angiotech, 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 into 2008
and plan to expand our manufacturing capacity in 2007 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. The manufacture of our products is subject to regulation and periodic inspection by the FDA and other regulatory bodies for compliance with quality
standards. There can be no assurance that the 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 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;

If we
or any of our third party manufacturers cannot produce our products, our product sales may suffer.

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 independent
sales agencies and direct sales representatives in the U.S. in order to market VITOSS, VITAGEL and IMBIBE. Outside of the U.S., we utilize a network of independent stocking distributors to market VITOSS, CORTOSS and ALIQUOT. We seek to strengthen
our field sales network through the addition of direct sales representatives in those U.S. territories where we either do not have independent sales agency coverage or the territories are underserved. We are dependent upon our distributors, sales
agencies and direct sales representatives 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.

There can be no assurance that the distributors and agencies will perform 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 and agencies. In addition, we cannot assure that our distributors and agencies will not develop independently,
or with other companies, other competitive products.

The independent U.S. agencies selling VITOSS generally sell products from other orthopedic companies.
A single agency 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 agencies lost their hardware product line provided by other orthopedic companies. Additionally, our independent agencies may be unable or unwilling to carry or effectively sell VITOSS as a result of the introduction of new
products into the market based upon other technologies that could compete with VITOSS. Our sales could be adversely affected if one or more of our successful agencies eliminated VITOSS from their product line for any other reason and terminated
their agency arrangement with us. Our sales could also be adversely affected if our independent agencies become concerned that their agency arrangement 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 and agencies, including our products, is an important factor in the distributors or agencies ability to penetrate the market. Accordingly, our ability to penetrate the markets
that we intend to serve is highly dependent upon the quality and breadth of the other

##### Table of Contents

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.

In an effort to further accelerate the growth of 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 implement this type of sales and distribution method.

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 may not 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, 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.

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. 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, all surgeons have not 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.

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, agents 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.

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 surgeons 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 new product acceptance. Healthcare providers may refuse to use our products if reimbursement is inadequate. We do not
yet know how reimbursement will be handled for all of our products because some procedures that use our products are new and reimbursement policies regarding these procedures have not been finalized. 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 profitably.

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 such 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



29

##### Table of Contents

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, 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.

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 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. Moreover, our failure to maintain strategic reserve supplies of each significant single-sourced material used to
manufacture VITOSS, CORTOSS and certain products that we may develop in the future may result in a breach of our material financing agreement with Royalty Trust. 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.

We have a supply
agreement which provides bovine collagen for the manufacture of VITAGEL. The initial term of the supply agreement expires in August 2008; however, we received notice in the first quarter of 2007 from our supplier of its intent to cease production of
bovine collagen between January 1, 2008 and June 30, 2008 and either close or sell its collagen processing facility by December 31, 2008. While we are seeking to obtain a strategic collagen reserve for VITAGEL, there is no assurance
that we will be successful. 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 find an alternative supplier with acceptable prices, quality and requisite regulatory approvals;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | our inability to obtain a strategic reserve of this collagen sufficient to meet our anticipated sales requirements;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | our inability to obtain collagen supply from this manufacturing facility if it is sold; or
| | - |  | ------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | delays caused by the need to secure PMA approval of a new manufacturing facility for the raw material.
| | - |  | ------------------------------------------------------------------------------------------------------

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 agreements 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 current supply contract may not permit us to supply materials to Angiotech or may otherwise be inadequate, and
we may need to seek additional suppliers for COSTASIS materials.

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. Our VITOSS is converted to 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.

Our pivotal CORTOSS
trial may not yield supportive or sufficient data, 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. The protocol for
the trial contemplates a 24 month follow up period for each patient, and we may be required to complete the follow up period for all enrolled patients in order to submit a 510(k) submission. The completion of our pivotal trial and submission package
for CORTOSS may be delayed or terminated for many 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;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | 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;

| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | 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 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 and IMBIBE labels. 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. The two pilot clinical studies are fully enrolled and we expect those trials to be completed by the third quarter
of 2007. During 2004, we received approval from the FDA to conduct a pivotal clinical study in the U.S. to further study the use of



32

##### Table of Contents

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 and ALIQUOT 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.

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



33



---

##### Table of Contents

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 and for the use of CORTOSS in screw
augmentation and vertebral augmentation procedures. 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, including VITAGEL.

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 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.

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. 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.

If we fail to meet our obligations under a revenue sharing agreement, we may be required to repurchase from an investor its right to receive revenues on certain of our product sales, and the investor could foreclose on certain assets
that are essential to our operations.

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 Trust. In this financing, we sold Royalty Trust a revenue interest and shares of our Common Stock. The revenue interest agreement provides 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 is subject to increase to a maximum rate of 4.375% on that portion of product sales that specifically relates to VITOSS and CORTOSS if we fail 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 2004, 2005 and 2006. We do not currently expect that changes in the revenue interest percentage resulting from fluctuations in sales of products subject to the revenue interest will have a material effect on operating results for
a period when considered relative to sales of the products for that period.

Throughout the term of the Royalty Trust revenue interest agreement, we are
required to make advance payments on the revenue interest obligation at the beginning of each year. The amount of the advance payment is $3,000,000 in each of the years 2008 through 2016. While we believe that we will have sufficient cash at the end
of 2007 to make the required $3,000,000 advance payment to Royalty Trust during 2008, we cannot be certain that we will have sufficient cash to meet our advance payment obligations for the years 2009 through 2016. Advance payments impact cash flow
when made, and they affect earnings only as the advance payments are credited within each period against the revenue interest actually earned by Royalty Trust during that year, with any excess advance payments refunded to us shortly after the end of
the year.

Our obligation to pay the revenue interest is secured by our licenses, patents and trademarks relating to certain of our products, including
VITOSS, CORTOSS and any structural bioactive device, in North America and Europe, the 12% royalty interest we pay to one of our wholly-owned subsidiaries on the sales of our products, and the shares of common stock of one



35



---

##### Table of Contents

of our wholly-owned subsidiaries (collectively, the Pledged Assets). We are also required to maintain:



| |  |  | Cash, cash equivalent and investment balances equal to or greater than the product of (i) 1.5 and (ii) total operating losses, net of non-cash charges,
for the preceding fiscal quarter; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | total shareholders equity of at least $8,664,374; provided, however, that under the provisions of the agreement with Royalty Trust, when calculating
shareholders equity for the purposes of the financial covenants, the revenue interest obligation is included in shareholders equity at its carrying value.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2006, we were in compliance with all financial covenants, and we do not expect to be out of compliance with the financial covenants within the next twelve months. However, if we fail to
maintain such balances and shareholders equity, Royalty Trust can demand that we repurchase its revenue interest.

In addition to the failure to
comply with the financial covenants described above, the occurrence of certain events, including those set forth below, triggers Royalty Trusts right to require us to repurchase its revenue interest:



| |  |  | a judicial decision that has a material adverse effect on our business, operations, assets or financial condition;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | the acceleration of our obligations or the exercise of default remedies by a secured lender under certain debt instruments;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | a voluntary or involuntary bankruptcy that involves us or our wholly owned subsidiary, Vita Special Purpose Corp.;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | our insolvency;
| | - |  | ---------------



| |  |  | a change in control of our company; and
| | - |  | ---------------------------------------



| |  |  | the breach of a representation, warranty or certification made by us in the agreements with Royalty Trust that, individually or in the aggregate, would reasonably
be expected to have a material adverse effect on our business, operations, assets or financial condition, and such breach is not cured within 30 days after notice thereof from Royalty Trust.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, our failure to maintain strategic reserve supplies of each significant single-source material used to manufacture VITOSS, CORTOSS and certain products that
we may develop in the future may result in a breach of our material financing agreement with Royalty Trust. We may not have sufficient cash funds to repurchase the revenue interest upon a repurchase event. The exact amount of the repurchase price is
dependent upon certain factors, including when the repurchase event occurs. If a repurchase event had been triggered and Royalty Trust exercised its right to require us to repurchase its revenue interest as of December 31, 2006, we would have
owed Royalty Trust approximately $24,000,000.

The repurchase price for Royalty Trusts revenue interest as of a given date is calculated in three
steps. First, a specified annual rate of return (25% effective October 16, 2005) is applied to Royalty Trusts $10,000,000 original purchase price from October 16, 2001 to the date of determination of the repurchase price. Second, the
result obtained from the first step of the calculation is added to the original $10,000,000 purchase price. Third, the sum obtained from the



36



---

##### Table of Contents

second step of the calculation is reduced by both $3,333,333 and the actual amount of revenue interest paid during the specified period.

If we were unable to repurchase the revenue interest upon a repurchase event, Royalty Trust could foreclose on the Pledged Assets, and we could be forced into
bankruptcy. Royalty Trust could also foreclose on the Pledged Assets if we became insolvent or involved in a voluntary or involuntary bankruptcy proceeding. No repurchase events or foreclosures have occurred as of December 31, 2006. In the
event that we repurchased Royalty Trusts revenue interest, Royalty Trust would have no obligation to surrender the shares of our Common Stock that it had purchased as part of the revenue interests assignment transaction.

Our results of operations may fluctuate due to factors out of our control, which could cause volatility in our stock price.

VITOSS, VITAGEL, CELLPAKER, IMBIBE, CORTOSS and ALIQUOT are currently our only products that have received regulatory clearances or approvals for sale. VITOSS is cleared
for sale in the U.S. and the European Union. VITAGEL, CELLPAKER and IMBIBE 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 VITOSS, VITAGEL,
CORTOSS, ALIQUOT, CELLPAKER and IMBIBE product sales are difficult to predict. VITOSS, VITAGEL and CELLPAKER product sales to date may not be indicative of future sales levels. VITOSS, CORTOSS and ALIQUOT sales levels in Europe may fluctuate due to
seasonality of elective surgeries and the timing of any distributor stocking orders and VITOSS, VITAGEL, IMBIBE and CELLPAKER 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 as a result of a number of additional factors, many of which are outside of our control. These factors include, but are not limited to:



| |  |  | the timing of governmental approvals or clearances for our products and our competitors products;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | unanticipated events associated with clinical and pre-clinical trials of our products;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | the medical communitys acceptance of our products;
| | - |  | ---------------------------------------------------



| |  |  | the timing in obtaining adequate third-party reimbursement of our products;
| | - |  | ---------------------------------------------------------------------------



| |  |  | the success of competitive products;
| | - |  | ------------------------------------



| |  |  | our ability to enter into strategic alliances with other companies;
| | - |  | -------------------------------------------------------------------



| |  |  | expenses associated with development and protection of intellectual property matters;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | establishment of commercial scale manufacturing capabilities;
| | - |  | -------------------------------------------------------------



| |  |  | events affecting logistics and elective surgery trends;
| | - |  | -------------------------------------------------------



| |  |  | the timing of expenses related to commercialization of new products;
| | - |  | --------------------------------------------------------------------



| |  |  | competitive disruptions to our distribution channels;
| | - |  | -----------------------------------------------------



| |  |  | the adequate training of a sufficient number of surgeons in the use of our products;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | pending or threatened offers to acquire us; and
| | - |  | -----------------------------------------------



| |  |  | timing of governmental approvals or clearances for us to manufacture the products we sell.
| | - |  | ------------------------------------------------------------------------------------------

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.

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 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 February 22, 2007, we own or control eighteen issued U.S. patents and nineteen pending patent applications in
the U.S., and several 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
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. Furthermore, the laws of foreign countries may not protect our intellectual property
rights to the same extent as the laws of the U.S. Finally, 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 result in a diversion of 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.

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 patents 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 patent, we could be prevented from selling that product unless we could obtain a license from the owner of the patent. 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 new or modified products and to revise our filings with the FDA, which is time consuming and expensive. If we were
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 agreements generally may be
terminated by our counterparty if we materially breach any of our obligations under the agreement. We may disagree with outside parties as to our and their obligations under the agreement or the interpretation of provisions in the agreement. Any
such disagreements could cause the other party 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 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 take 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 market. 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. Further, in 2004, the spinal bone grafting market saw the introduction of total disk replacement devices (TDRs) as treatment
alternative for degenerative disc disease designed to preserve the motion of the vertebrae of the spine. Our products could be rendered noncompetitive or obsolete by these and other 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 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;
| | - |  | -----------------------------------------

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

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

We may acquire technologies 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 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 or technology.

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 our common shareholders. 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 the common stock.
| | - |  | ----------------------------------------------------------------

Our stock price may be volatile.

Our stock price, like that of many small cap medical technology companies, may 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 may
adversely affect the market price of our common stock. The following factors could also cause our stock price to be volatile or decrease:



| |  |  | fluctuations in our results of operations;
| | - |  | ------------------------------------------



| |  |  | under-performance in relation to analysts estimates or financial guidance provided by us;
| | - |  | ------------------------------------------------------------------------------------------



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

If
we are sued in a product liability action, we could be forced to 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 a product liability lawsuit. In particular, the market for spine products has a history of product liability litigation.
Under certain of our agreements with our distributors, sales agencies and hospital customers, we indemnify the distributor, sales agency or hospital 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. 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 result in the diversion of 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.

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, despite our use of confidentiality agreements.

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 was 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 revenue and operating results.

If we fail to comply with the FDAs Quality
System Regulation, our manufacturing operations could be halted, and our business would suffer.

We are currently required to demonstrate and maintain
compliance with the FDAs Quality System Regulation, or QSR. The QSR is a 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. Our failure to comply with the QSR or to take satisfactory corrective action
in response to an adverse QSR inspection could result in enforcement actions, including a public warning letter, a shutdown of or restrictions on our manufacturing operations, delays in approving or clearing a product, refusal to permit the import
or export of our products, a recall or seizure of our products, fines, injunctions, civil or criminal penalties, or other sanctions, any of which could cause our business and operating results to suffer.

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; expected results of our CORTOSS pivotal clinical trial in the U.S.; our ability to raise capital; capital expenditures; future liquidity; uses of cash; expected sales product mix and related margins; equity compensation expense; the
development of our sales network; the cost to expand our manufacturing and operating facilities; our ability to manage our manufacturing facilities and requirements; availability of raw materials; our ability to satisfy financial covenants in our
revenue interest agreement and other lending agreements; the adequacy of inventory; development costs for existing and new products; 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 included in this Form 10-K. In addition, our performance and financial results could differ materially from those reflected in the forward-looking statements due to general financial,
economic, regulatory and political conditions affecting the biotechnology, orthopedic and medical device industries.

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 2006 increased 35% to $46,828,047 from $34,679,298
in 2005. 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 at least the next several years as we plan to continue to expand our sales and marketing activities,
pursue product development efforts, further develop our manufacturing capabilities and attempt to increase manufacturing efficiencies.

The following
summarizes our principal cash commitments at December 31, 2006 and, as of the

##### Table of Contents

date of this report, our principal anticipated expenditures:



| | - | Agreement with Kensey. Approximately 61% of our product sales during the year ended December 31, 2006 were
from products based upon our VITOSS®FOAM platform co-developed with Kensey. As of
December 31, 2006, we owed Kensey $1,277,886 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.
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - | Advance Payment to Royalty Trust.Throughout the term of the Royalty Trust revenue interest agreement, we are required to make advance payments to Royalty Trust on the
revenue interest obligation at the beginning of each year. The amount of the advance payment is $3,000,000 in each of the years 2007 through 2016. We paid the 2007 $3,000,000 advance payment in January 2007. We believe that we will have sufficient
cash at the end of 2007 to make the required $3,000,000 advance payment to Royalty Trust for 2008. See Note 7 to our consolidated financial statements included in this report for additional information.
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - | Operations  We expect to use cash, cash equivalents and investments, together with proceeds of indebtedness and capital expected to be raised from external sources, 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 expect to raise additional capital from external sources in
order to support the expansion of our sales force and fund operations.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | - | CORTOSS clinical study and research and development  We expect to incur approximately $2.5 million in external costs during 2007 and 2008 in the
completion of the CORTOSS pivotal clinical study in the U.S. Following completion of patient enrollment for the study in February 2007, we will monitor the patients and collect, consolidate and analyze the clinical data in preparation for our
submission of the CORTOSS 510(k) filing to the FDA. During 2007, 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.
| | -------------------------------------



| | - | Expansion of manufacturing capacity  We expect to spend approximately $3.8 million for plant renovations and equipment during 2007 to expand our capacity to manufacture
VITAGEL and ancillary products such as ALIQUOT, IMBIBE and CELLPAKER, at sites we currently lease. We plan to finance the renovations and equipment through cash on hand, borrowings and capital leases under an equipment line of credit.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We believe our existing cash, cash equivalents, and investments of $28,338,522 as of December 31, 2006 will be sufficient to meet our
currently estimated operating and investing requirements into at least the second quarter of 2008. We plan to seek to obtain additional funds at any time through equity or debt financings, or strategic alliances with third parties either alone or in
combination with equity or debt financings. We will consider a variety of factors, such as availability of capital, opportunity to raise capital, the business goals of potential strategic partners and other third parties, and market conditions, in
determining when to seek to raise these additional funds.

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, 2006, 2005 and 2004 of $902,593, $486,588 and
$220,400, respectively, for sales of Endoskeleton products.

CRITICAL ACCOUNTING POLICIES

The preparation of our 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 of
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



48

##### Table of Contents

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 was 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.

The products that are 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 December 31, 2006 and for the foreseeable future, we cannot currently make a reasonable estimate of future revenues and
payments that may become due to Royalty Trust under this financing. Therefore, it is premature to estimate the expected impact of this financing on our results of operations, liquidity and financial position. Accordingly, given these uncertainties,
we have charged and, for the foreseeable future, we will continue to charge revenue interest expense for the revenue interest due to Royalty Trust as revenues subject to the revenue interest obligation are recognized (see Note 7). Revenue interest
expense of $1,179,466, $989,287 and $837,844 has been recorded for the years ended December 31, 2006, 2005 and 2004, respectively. The revenue interest under this agreement is treated as interest expense in accordance with EITF No. 88-18.

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. Since it is more likely than not that a tax benefit will not be realized against all of our deferred tax assets due to our history of
operating losses, a valuation allowance has been established against all of our deferred tax assets.

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 required 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

##### Table of Contents

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
Emerging Issues Task Force (EITF) Issue No. 00-19, Accounting for Derivative Instruments (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 received from sales of our stock and other securities. Cash, cash equivalents and
investments were $28,338,522 at December 31, 2006, and include $26,573,492 in net proceeds received in November and December 2006 from the sale of 8,819,128 shares of our Common Stock in a registered underwritten offering. During 2006,
$16,037,621 of cash was used in operations, which included $2,538,052 for the decrease in inventory and accounts payable, net of an increase in accounts receivable.

We invest excess cash in highly liquid investment-grade marketable securities including corporate commercial paper and U.S. government agency bonds. As of December 31, 2006 and 2005, cash, cash equivalents and
investments consisted of the following:

NET CASH USED IN OPERATING ACTIVITIES

OPERATING CASH INFLOWS

Operating cash inflows for the years ended December 31, 2006, 2005, and 2004 were
derived primarily from VITOSS, VITAGEL and IMBIBE product sales in the U.S. and from VITOSS, CORTOSS and ALIQUOT product sales outside the U.S. We have also received cash inflows from interest income on cash equivalents and investments.

OPERATING CASH OUTFLOWS

Our operating cash outflows for the year ended December 31, 2006 have primarily been used to fund operations. Operational cash outflows include (i) headcount related costs to expand our field sales team; (ii) increased
payment of sales commissions on growing product sales, (iii) purchases of product inventory from Kensey Nash Corporation (Kensey); (iv) payment of the contractually required advance payment of $1,750,000 to Paul Royalty; and
(v) the production of VITAGEL and CORTOSS inventory, and (v) expenses related to our clinical trial in the U.S. for CORTOSS.

OPERATING CASH
FLOW REQUIREMENTS OUTLOOK

We expect to continue to focus our efforts on sales growth under our VITOSS and VITAGEL product platforms in 2007. We
launched VITOSS Cancellous Chips and the VITAGEL Spray Set during the first quarter of 2006. In an effort to further increase sales of our new VITOSS and VITAGEL product lines in future quarters, we may add direct sales representatives to our
organization for those territories in the U.S. where we either do not currently have independent sales agency coverage or the territory is underserved. In addition, we intend to fund additional studies to collect and publish post-clinical data
relating to the performance of VITOSS to support our marketing and sales efforts and to fund the expansion of our manufacturing capability.

Additionally,
we expect to continue to use cash, cash equivalents and investments to fund our operations until we are profitable, if ever. We anticipate that 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 at least the next several years as we plan to continue to expand our sales and marketing activities, pursue product development efforts and further develop our manufacturing
capabilities. During 2007, 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.
We expect to incur approximately $2,500,000 in external costs during 2007 and 2008 in the completion of the CORTOSS pivotal clinical study in the U.S. Following completion of patient enrollment for the study in February 2007, we will incur costs to
monitor the patients and collect, consolidate and analyze the clinical data in preparation for our submission of the CORTOSS 510(k) filing to the FDA. We expect the expense for this clinical program to decrease significantly after the submission, if
any, of an application to the FDA for clearance to market CORTOSS in the U.S. for the treatment of osteoporotic vertebral compression fractures. However, the overall level of our research & development expense in future periods will depend
upon the development status and costs of products currently in our pipeline and any new products that we may determine to pursue. We may also incur additional expense to support the launch of CORTOSS if it receives FDA clearance.

Our operating cash requirements are heavily dependent upon our product sales mix allocation among higher and lower margin products, the timing of receipt of FDA 510(k)
clearance for new products, the timing of inventory builds to support product launches and related inventory valuations, the timing of subsequent launches and acceptance of our new product lines, the rate

at which we add new direct sales representatives and the rate at which our field sales network generates sales in their respective territories. Accordingly,
in 2007, our operating cash requirements will continue to be subject to quarterly volatility. Until such time that sales levels are sufficient to sustain operations, if ever, we expect to continue to use cash, cash equivalents and investments to
fund operating activities and we expect to continue to need to sell securities to fund our operating activities. We cannot guarantee that we will be able to sell securities at a price that fully reflects the long term value, if any, of the
investments we may make in building our sales force, expanding our manufacturing capability, creating manufacturing efficiencies, or developing and commercializing new products.

Agreement with Kensey.As of December 31, 2006, we owed Kensey $1,277,886 for manufactured product inventory and royalties, which are included in accounts payable and other accrued expenses on the
Consolidated Balance Sheet.

Agreement with Angiotech.As of December 31, 2006, we owed Angiotech $52,783 for royalties, which is included in
accounts payable and other accrued expenses on the Consolidated Balance Sheet.

Revenue Interest. The revenue interest agreement provides 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 is subject to increase to a maximum rate of 4.375% on that portion of product sales that specifically relates to VITOSS and CORTOSS, if we fail 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 2004, 2005 and 2006.

Throughout the term of the Royalty Trust revenue interest
agreement, we are 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. 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. In January 2007, we paid Royalty Trust the advance payment for 2007 of $3,000,000. The amount of the advance payment remains $3,000,000 in each of the years 2008 through 2016. While we believe that we will have sufficient cash
at the end of 2007 to make the required $3,000,000 advance payment to Royalty Trust during 2008, we cannot be certain that we will have sufficient cash to meet our advance payment obligations for the years 2009 through 2016. Advance payments impact
cash flow when made, and they affect earnings only as the advance payments are credited within each period against the revenue interest actually earned by Royalty Trust during that year, with any excess advance payments refunded to us shortly after
the end of the year.

The products that are subject to the revenue interest agreement have been approved and launched at various times over the last four
years or are still under development. For these reasons, as of

##### Table of Contents

December 31, 2006, and for the foreseeable future, we cannot currently make a reasonable estimate of future revenues and payments that may become due to
Royalty Trust under this financing.

Our obligation to pay the revenue interest is secured by: (i) licenses, patents and trademarks relating to
certain of our products, including VITOSS, CORTOSS and any structural device, in North America and Europe; (ii) the 12% royalty interest we pay to Vita Licensing, Inc., our wholly-owned subsidiary, on the sales of our products pursuant to a
licensing arrangement; and (iii) the shares of Common Stock of Vita Special Purpose Corp. owned by Vita Licensing, Inc. If we default under our agreement with Royalty Trust, Vita Special Purpose Corp. cannot pay any dividends or make any
distributions to us or Vita Licensing, Inc. As of December 31, 2006, we were in compliance with all financial covenants under the revenue interest agreement and do not expect to fall out of compliance for at least the next twelve months.
However, if we fail to maintain certain specified balances and shareholders equity, Royalty Trust can demand that we repurchase its revenue interest. We may not have sufficient cash funds to repurchase the revenue interest upon a repurchase
event. The exact amount of the repurchase price is dependent upon certain factors, including when the repurchase event occurs. If a repurchase event had been triggered and Royalty Trust exercised its right to require us to repurchase its revenue
interest as of December 31, 2006, we would have owed Royalty Trust approximately $24,000,000.

NET CASH USED IN INVESTING ACTIVITIES

INVESTING CASH INFLOWS

During 2006 and 2005, we
received proceeds of $24,875,000 and $20,915,000, respectively, from the sale of investments.

INVESTING CASH OUTFLOWS

In 2006, we purchased the profit-sharing royalty rights for VITAGEL and CELLPAKER for $9,000,000. Accordingly, we will no longer pay Angiotech royalties for VITAGEL
product sales in 2007 and thereafter. The $9,000,000 payment has been recorded as a License Right Intangible on the Consolidated Balance Sheet as of December 31, 2006. This amount will be 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.

We have invested $1,378,271, $1,470,080, $1,424,513 for the years ended December 31, 2006, 2005, and 2004, respectively, primarily for the purchase
of equipment, leasehold improvements, and research and development equipment in order to further expand our product development and manufacturing capabilities relating to VITAGEL and VITOSS.

In March 2006, we entered into a lease for approximately 13,000 square feet of finished and unfinished space for a new, additional office location in the Great Valley
Corporate Center in Malvern, Pennsylvania. The initial term of the lease is six years and the initial annual base rent

under the lease is approximately $116,500. During the third quarter of 2006, we completed the renovation of the new office location. In September 2006, we
relocated our executive, administrative and research and development personnel and headquarters there from another building, which space we continue to occupy, within the same corporate center. The Company spent approximately $700,000 during the
second half of 2006 in connection with the renovation and moving costs for the new headquarters. This amount was funded through cash on hand, borrowings and capital leases under an equipment line of credit.

Cash used for the purchase of investments was $17,826,431, $21,105,775, and $18,928,019 during the years ended December 31, 2006, 2005, and 2004, respectively.

INVESTING CASH OUTLOOK

We expect to spend
approximately $4,000,000 for expansion of our manufacturing facility, leasehold improvements and capital equipment during the 2007 fiscal year. We plan to finance the renovations associated with the expansion of our manufacturing capacity and other
new capital investments through cash on hand, borrowings and capital leases under an equipment line of credit.

NET CASH PROVIDED BY FINANCING
ACTIVITIES

FINANCING CASH INFLOWS

During the year
ended December 31, 2006, we sold 8,819,128 shares of Common Stock for net proceeds of $26,573,492 in a registered, underwritten offering. During the year ended December 31, 2005, we sold 4,318,182 shares of Common Stock for net proceeds of
$12,929,546. During the year ended December 31, 2004, we sold 5,681,818 shares of Common Stock for net proceeds of $24,024,375.

During the year ended
December 31, 2006, we received $462,337 and $102,253 from stock option exercises and purchases of Common Stock under our Employee Stock Purchase Plan, respectively. During the year ended December 31, 2005, we received $218,717 and $86,812
from stock option exercises and purchases of Common Stock under our Employee Stock Purchase Plan, respectively. During the year ended December 31, 2004, we received $514,288, $696,932 and $82,135 from warrant exercises, stock option exercises
and purchases of Common Stock under our Employee Stock Purchase Plan, respectively.

For the years ended December 31, 2006, 2005 and 2004, we issued
notes payable of $683,950, $1,572,514 and $537,974, respectively, in connection with the purchase of property and equipment.

FINANCING CASH OUTFLOWS

During the years ended December 31, 2006, 2005 and 2004, we repaid $727,883, $523,392 and $440,088, respectively, of notes payable and capital
lease obligations.

FINANCING REQUIREMENTS OUTLOOK

We do not expect sales to generate cash flow in excess of operating expenses for at least the next several years, if ever. Until such sales levels are achieved, we expect to continue to use cash, cash equivalents, and
investments to fund operating and investing activities. We believe our existing cash, cash equivalents, and investments of $28,338,522 as of December 31, 2006 will be sufficient to meet our currently estimated operating and investing
requirements at least into the second quarter of 2008. We will seek to finance new capital investments through borrowings or capital leases under an equipment line of credit. In addition, we may seek to finance our working capital needs through a
line of credit, and plan to seek additional funds through equity or debt financings, or strategic alliances with third parties either alone or in combination with equity or debt financings.

We have an effective Form S-3 universal shelf registration statement filed with the Securities and Exchange Commission for the potential additional issuance of up to
approximately $11,000,000 of our securities, and plan to file another shelf registration statement. The existing registration statement provides us with the flexibility to determine the type of security we choose to sell, including common stock,
preferred stock, warrants and debt securities. However, the filing of a registration statement does not insure that securities covered by the registration statement will, in fact, be sold, and we could sell securities in other transactions not
registered on that registration statement. Moreover, if we raise additional capital by issuing equity securities, the terms and prices for these financings may be more favorable to the new investors than the terms obtained by our existing
shareholders. These financings also may significantly dilute the ownership of existing shareholders. If we raise additional capital by accessing debt markets, the terms of these financings may require liens on certain of our assets that may limit
our flexibility. Additional equity or debt financing, however, may not be available on acceptable terms from any source.

The extent and timing of proceeds
from future stock option and warrant exercises, if any, are primarily dependent upon our Common Stocks market price, as it relates to the exercise prices and expiration dates of the stock options and warrants.

Notes Payable and Capital Lease Obligations. During July 2002, we entered into a financing arrangement with a lending institution. The arrangement provided
individual notes payable with a term of 35 or 48 months from the date of issuance for each note. The notes payable are secured by certain capital assets. During 2006, we issued six individual notes with an aggregate principal amount of $683,950 and
weighted average annual interest rates of approximately 11.79%. During 2005, we issued two notes with an aggregate principal amount of $1,572,514 and weighted average annual interest rates of approximately 11.19%. In addition, during 2004, we issued
two notes with an aggregate principal amount of $537,974 and weighted average annual interest rates of approximately 11.43%. As of December 31, 2006, future minimum payments under notes payable and capital lease obligations are as set forth in

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.

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.

Comparison of the Year Ended
December 31, 2005 to the Year Ended December 31, 2004

Product Sales. Product sales for 2005 increased 41% to $34,679,298 from
$24,661,382 in 2004. Sales growth was primarily attributable to the expansion of our existing product portfolio and improved market penetration in the U.S., reflecting the increased size of the U.S. field sales network, which resulted in improved
market coverage.

For the years ended December 31, 2005 and 2004, 93% of product sales were in the U.S., primarily from sales of VITOSS and IMBIBE.
The remaining sales, during 2005 and 2004, were a result of VITOSS, CORTOSS and ALIQUOT sales outside the U.S., primarily in Europe.

Gross Profit.
Gross profit for 2005 and 2004 was $22,027,720 and $16,902,490, respectively. Gross margin was 64% for 2005, as compared to 69% for 2004. The gross margins for 2005 and 2004 were negatively impacted by adjustments to write down inventory to its
estimated net realizable value in the amounts of $1,606,420 and $1,590,856, respectively. The write downs of inventory arose from the shift in product mix toward certain VITOSS FOAM products introduced in 2004 and one-year shelf-life packaging on
other VITOSS FOAM products. The $1,606,420 and $1,590,856 adjustments to write down inventory during the years ended December 31, 2005 and 2004, respectively, lowered the gross margin by 4% and 6% for the periods, respectively. The lower gross
margin for 2005 as compared to 2004 was further affected by the shift in product mix towards the VITOSS FOAM product platform, which has a lower gross margin on a higher average selling price per unit as compared to our other products, as well as
towards the VITAGEL Surgical Hemostat product, which also has lower gross margins as compared to our other products.

Operating Expenses. Operating
expenses for the years ended December 31, 2005 and 2004 were $34,955,082 and $29,439,511, respectively, which represents a 19% increase as compared to a 41% increase in product sales for 2005 as compared to 2004.

General and administrative expenses for 2005 increased 19% to $6,661,628 from $5,595,049 for 2004 primarily due to additional headcount, general legal costs and
insurance-related expenses. General and administrative expenses decreased to 19% of product sales for 2005 as compared to 23% of product sales for 2004.

Selling and marketing expenses were $21,126,567 for the year ended December 31, 2005, a 16% increase from $18,187,113 for the year ended December 31, 2004. Selling and marketing expenses increased for 2005 primarily due to higher
salary and benefit costs attributable to increasing the size of our sales management team and expanding our field sales team of direct sales representatives to support the growth of U.S product sales. The remainder of the increase in selling and
marketing expenses was due to higher commissions paid in the U.S. as a result of increased product sales in 2005. Selling and marketing expenses decreased to 61% of product sales for 2005 as compared to 74% of product sales for 2004.

##### Table of Contents

Research and development expenses increased to $7,166,887 for 2005 from $5,657,349 for 2004. The 27% increase is
primarily due to costs associated with our CORTOSS clinical trial in the U.S. Research and development expenses decreased to 21% of product sales for 2005 as compared to 23% of product sales for 2004.

Net other expense. Net other expense includes interest income, interest expense and revenue interest expense. We recorded $435,979 and $661,003 of net other
expense for the years ended December 31, 2005 and 2004, respectively. The decrease in net other expense is primarily attributed to higher interest income of $577,000 as a result of higher average cash, cash equivalent, and investment balances
partially offset by higher interest expense of $201,000 primarily related to amortization of investments and higher revenue interest expense of $151,000 incurred under the arrangement with Royalty Trust due to higher product sales.



|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, 2006, our total exposure to foreign currency risk in U.S. dollar terms was approximately $2,350,000, or 3.8%, 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 $235,000 at December 31, 2006.

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, 2006 and 2005, 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, 2006. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2006 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, 2006. 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, 2006, the Companys internal control over financial reporting was effective.

The
Companys independent registered public accounting firm, KPMG LLP, has audited managements assessment of the Companys internal control over financial reporting. KPMG LLPs report on managements assessment and on the
effectiveness of the Companys internal control over financial reporting appears below.

Changes in Internal Control Over Financial Reporting

We made changes in our internal control over financial reporting during 2006, including the
fourth quarter of 2006, that materially affected our internal control over financial reporting. In particular, we instituted the enhancements set forth below to our internal control over financial reporting to remediate the material weakness
described in Managements Annual Report on Internal Control Over Financial Reporting contained in our Annual Report on Form 10-K for the year ended December 31, 2005. The material weakness related to ineffective internal controls
associated with the physical count and compilation of inventory as of December 31, 2005.



| |  |  | We implemented a monthly physical inventory cycle count program during March 2006 to identify book to physical inventory differences, if any, on a timely basis.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We realigned job responsibilities and staffing to effectively manage the physical inventory count and compilation of inventory.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | Physical inventory procedures were reviewed and additional training was provided to counters and management prior to the taking of physical inventory during the
fourth quarter of 2006.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | During the second quarter of 2006, we implemented certain functionality within our automated inventory system controls to provide greater accuracy over physical
inventory locations within our warehouse.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There was no other change in our internal control over financial reporting during the quarter
ended December 31, 2006, that have materially affected, or is 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 management's assessment, included in the accompanying Managements Annual Report on Internal Control Over Financial Reporting that Orthovita, Inc. and subsidiaries (the Company) maintained
effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion
on management's assessment and an opinion on the effectiveness of 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, evaluating management's assessment, testing and evaluating the design and operating
effectiveness of internal control, and 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, management's assessment that the Company maintained effective internal control over financial reporting as of December 31, 2006, is fairly stated,
in all material respects, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in our opinion, the

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, 2006 and 2005, and the related statements of

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 as of December 31, 2006 and 2005, 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, 2006. 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, 2006 and 2005, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2006, 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), the effectiveness of Orthovita, Inc.s internal control over financial reporting as of December 31, 2006, based on criteria
established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 16, 2007 expressed an unqualified opinion on managements
assessment of, and the effective operation of, 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. (collectively with its affiliates and parent company, Angiotech Pharmaceuticals, Inc, which is a 9.3% shareholder of the Company, 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 sales agencies 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, and ALIQUOT®Delivery System.

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. For the 2004 basic and diluted net loss per common share calculations, we assumed that 117 outstanding shares of Preferred Stock were converted into 685,816 shares of Common Stock as of December 31, 2004 as these
shares automatically converted to Common Stock when the beneficial ownership limitation applicable to the holders of the shares lapsed during 2005 (see Note 11). As of December 31, 2005 and 2006, no shares of Preferred Stock were outstanding.

Common Stock options and warrants exercisable to purchase 9,124,280, 8,671,183, and 7,819,977 shares were excluded from our computation of diluted net
loss per common share for the years ended December 31, 2006, 2005, and 2004, 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. 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.

The products that are 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 December 31, 2006 and for the foreseeable future, we cannot currently make a reasonable estimate of future revenues and
payments that may become due to Royalty Trust under this financing. Therefore, it is premature to estimate the expected impact of this financing on our results of operations, liquidity and financial position. Accordingly, given these uncertainties,
we have charged and, for the foreseeable future, we will continue to charge revenue interest expense for the revenue interest due to Royalty Trust as revenues subject to the revenue interest obligation are recognized (see Note 7). Revenue interest
expense of $1,179,466, $989,287 and $837,844 has been recorded for the years ended December 31, 2006, 2005 and 2004, respectively. The revenue interest under this agreement is treated as interest expense in accordance with EITF No. 88-18.

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



F-8



---

##### Table of Contents

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. Since it is more likely than not that a tax benefit will not be realized against all of our deferred tax assets due to our history of
operating losses, a valuation allowance has been established against all of our deferred tax assets.

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 year ended December 31, 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

##### Table of Contents

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.

The fair value of stock-based awards for all outstanding and unvested stock option grants was estimated using the
Black-Scholes option pricing model with the following weighted average assumptions for the years ended December 31, 2006, 2005 and 2004:



|                        |  |                         |   |  |         |   |  |         |

|                        |  | 2006                    |   |  | 2005    |   |  | 2004    |  
|Risk-free interest rate |  | 4.74                    | % |  | 4.32    | % |  | 2.90    | %
|Expected Volatility     |  | 60                      | % |  | 81      | % |  | 86      | %
|Dividend yield          |  | 0                       | % |  | 0       | % |  | 0       | %
|Expected life           |  | 5 years                 |   |  | 6 years |   |  | 6 years |  

The weighted average fair value of options was $2.02, $2.70 and $2.94 in 2006, 2005 and 2004, respectively.

For the years ended December 31, 2006, 2005 and 2004, 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 the same periods in 2005 and 2004 was primarily due to a decrease in the expected life of the options from six years for the years ended December 31, 2005 and 2004 to five
years for the year ended December 31, 2006.

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 years ended December 31, 2005 and 2004, 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 2006, 2005 and 2004, respectively, we issued options and/or warrants for the
purchase of 40,000, 48,398 and 129,250 shares of Common Stock with various exercise prices to certain vendors in consideration for services valued at $125,357, $146,313 and $439,068, respectively. We recorded a non-cash adjustment in 2006 for the
change in fair market value of our fully-vested non-employee consultant stock options outstanding. See Note 3.

During 2004, we modified the terms of
certain incentive stock option agreements in consideration for services valued at $16,477.

In 2005 and 2004, we issued 9,667 and 10,434 shares of Common
Stock, respectively, valued at $38,093 and $47,798, respectively, pursuant to a clinical assessment agreement.

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

In 2006 and 2005, we incurred capital lease obligations of $322,469 and $107,982, respectively.

In 2006, 2005 and 2004, cash paid for interest expense and revenue interest expense aggregated $1,424,958, $1,074,197 and $933,592, respectively.

Recent Accounting Pronouncements

See Accounting for Stock Options
Issued to Employees above in this Note, as well as Note 3, for information regarding SFAS 123R.

In December 2004, the FASB issued SFAS No. 151,
Inventory Costs, which clarifies the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Under SFAS No. 151, such items will be recognized as current-period charges. In
addition, SFAS No. 151 requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS No. 151 was effective for the Company for inventory costs incurred
on or after January 1, 2006. The adoption of SFAS No. 151 did not have a material impact on our 2006 financial statements.

In July 2006, the
FASB issued FIN No. 48, Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109, which provides criteria for the recognition and measurement of uncertain tax positions. FIN No. 48 requires
that an uncertain tax position should be recognized only if it is more likely than not that the position is sustainable based on its technical merits. Recognizable tax positions should then be measured to determine the amount of benefit
recognized in the financial statements. The provisions of FIN No. 48 are effective for fiscal years beginning after December 15, 2006. The Company has evaluated the provisions of FIN No. 48 and has determined that the impact of the
adoption of FIN No. 48 on its financial statements will not be material.

Reclassifications

Certain amounts from prior years have been reclassified to conform to the 2006 presentation.

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

Accounting for Stock Options
Issued to Non-employees

During the years ended December 31, 2006 and 2005, we granted options for the purchase of an aggregate of 25,000 and 48,398
shares of Common Stock with various exercise prices to certain consultants in consideration for services. The $80,403 and $153,209 aggregate grant date fair value of these options for 2006 and 2005, respectively, was included in selling and
marketing expenses in our Consolidated Statements of Operations during the applicable period. Additionally, during the year 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 Instruments, 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 year ended December 31, 2006. The change in fair value is recorded as a reduction in expenses for the year ended December 31, 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 Operations.

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,
2006.

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



|                        |  |   |         |

|Dividend yield          |  |   | 0       | %
|Life                    |  |   | 5 years |  

As of December 31, 2006, our non-employee consultants held fully-vested stock options to purchase 901,748
shares of our Common Stock, at an average exercise price of $3.57 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.

4. Cash, Cash Equivalents and Investments:

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, 2006 and 2005, cash, cash equivalents and investments consisted of the following:

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 $7,167,000.

The revenue interest agreement
provides 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

##### Table of Contents

revenue interest percentage is subject to increase to a maximum of 4.375% on that portion of product sales that specifically relates to VITOSS and CORTOSS,
if we fail 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 are 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 Royalty Trust in 2005, $989,287 was earned in 2005 and the balance of $610,713 was included in prepaid revenue interest expense on the accompanying consolidated balance sheet
as of December 31, 2005, and 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 January 2007, we paid Royalty Trust the $3,000,000 advance payment for 2007. The amount
of the advance payment remains $3,000,000 in each of the years 2008 through 2016. While we believe that we will have sufficient cash at the end of 2007 to make the required $3,000,000 advance payment to Royalty Trust during 2008, we may not have
sufficient cash to meet our advance payment obligations for the years 2009 through 2016. Advance payments impact cash flow when made, and they affect earnings only as the advance payments are credited within each period against the revenue interest
actually earned by Royalty Trust during that year, with any excess advance payments refunded to us shortly after the end of the year.

The products that
are 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, and for the foreseeable future, we cannot
currently make a reasonable estimate of future revenues and payments that may become due to Royalty Trust under this financing. Therefore, it is premature to estimate the expected impact of this financing on our results of operations, liquidity and
financial position. Given these uncertainties, we have determined not to amortize any portion of the liability attributable to the revenue interest obligation, and we have charged and, for the foreseeable future, we will continue to charge, 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 are recognized. Revenue interest expense of $1,179,466, $989,287 and $837,844 was recorded
for the years ended December 31, 2006, 2005 and 2004, respectively.

Our obligation to pay the revenue interest is secured by our licenses, patents
and trademarks relating to certain of our products, including VITOSS, CORTOSS and any structural bioactive device, in North America and Europe, the 12% royalty interest we pay to one of our wholly-owned subsidiaries on the sales of our products, and
the shares of common stock of one of our wholly-owned subsidiaries (collectively, the Pledged Assets). We are also required to maintain:

| |  |  | Cash, cash equivalent and investment balances equal to or greater than the product of (i) 1.5 and (ii) total operating losses, net of non-cash charges,
for the preceding fiscal quarter; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | total shareholders equity of at least $8,664,374; provided, however, that under the provisions of the agreement with Royalty Trust, when calculating
shareholders equity for the purposes of the financial covenants, the revenue interest obligation is included in shareholders equity at its carrying value.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As of December 31, 2006, we were in compliance with all financial covenants under the revenue interest agreement. However, if we fail to maintain certain specified balances and shareholders equity, Royalty
Trust can demand that we repurchase its revenue interest. In addition to the failure to comply with the financial covenants described above, the occurrence of certain events, including those set forth below, triggers Royalty Trusts right to
require us to repurchase its revenue interest:



| |  |  | a judicial decision that has a material adverse effect on our business, operations, assets or financial condition;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | the acceleration of our obligations or the exercise of default remedies by a secured lender under certain debt instruments;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | a voluntary or involuntary bankruptcy that involves us or our wholly owned subsidiary, Vita Special Purpose Corp.;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | our insolvency;
| | - |  | ---------------



| |  |  | a change in control of our company; and
| | - |  | ---------------------------------------



| |  |  | the breach of a representation, warranty or certification made by us in the agreements with Royalty Trust that, individually or in the aggregate, would reasonably
be expected to have a material adverse effect on our business, operations, assets or financial condition, and such breach is not cured within 30 days after notice thereof from Royalty Trust.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, our failure to maintain strategic reserve supplies of each significant single-source material used to manufacture VITOSS, CORTOSS and certain products that
we may develop in the future may result in a breach of our material financing agreement with Royalty Trust. We may not have sufficient cash funds to repurchase the revenue interest upon a repurchase event. The exact amount of the repurchase price is
dependent upon certain factors, including when the repurchase event occurs. If a repurchase event had been triggered and Royalty Trust exercised its right to require us to repurchase its revenue interest as of December 31, 2006, we would have
owed Royalty Trust approximately $24,000,000. As of December 31, 2006, we do not expect to be out of compliance with the financial covenants of the revenue interest obligation within the next twelve months.

The repurchase price for Royalty Trusts revenue interest as of a given date is calculated in three steps. First, a specified annual rate of return (25% effective
October 16, 2005) is applied to Royalty Trusts $10,000,000 original purchase price from October 16, 2001 to the date of determination of the repurchase price. Second, the result obtained from the first step of the calculation is
added to the original $10,000,000 purchase price. Third, the sum obtained from the



F-17

##### Table of Contents

second step of the calculation is reduced by both $3,333,333 and the actual amount of revenue interest paid during the specified period.

If we were unable to repurchase the revenue interest upon a repurchase event, Royalty Trust could foreclose on the Pledged Assets, and we could be forced into
bankruptcy. Royalty Trust could also foreclose on the Pledged Assets if we became insolvent or involved in a voluntary or involuntary bankruptcy proceeding. No repurchase events or foreclosures have occurred as of December 31, 2006. In the
event that we repurchased Royalty Trusts revenue interest, Royalty Trust would have no obligation to surrender the shares of our Common Stock that it had purchased as part of the revenue interest assignment transaction.

If we know that we will not be in compliance with our covenants under the Royalty Trust agreement, we will be required to adjust the revenue interest obligation to equal
the amount required to repurchase Royalty Trusts revenue interest.

8. Notes Payable and Capital Lease Obligations:

Approximately 60%, 60% and 42% of our product sales during the years ended December 31, 2006, 2005 and 2004,
respectively, were from products based upon our VITOSS FOAM platform co-developed with Kensey (see Note 14). 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.

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 components of income taxes are as follows:

##### Table of Contents

The difference between our federal statutory income tax rate and our effective income tax rate is primarily due to
permanent items, state income taxes and changes in the valuation allowance.

Components of our deferred tax asset as of December 31, 2006 and 2005 are
as follows:

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 since the realization of the deferred tax asset is not assured 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.

As of December 31, 2006, we had approximately $76,600,000 of federal net operating loss carryforwards, $78,800,000 of state net operating loss
carryforwards and $10,600,000 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 $2,000,000
in 2006 and will increase 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 $1,248,487 and $142,831 begin to expire in 2010 and 2014,
respectively.

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, 2006, 2005 and 2004, we purchased
$3,624,662, $4,808,552 and $6,614,458, respectively, of product inventory manufactured by Kensey on our behalf. As of December 31, 2006 and December 31, 2005, we owed Kensey $1,277,886 and $1,323,595, 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.

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

##### Table of Contents

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

will be 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 year ended
December 31, 2006, we purchased $64,944 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.

During the year ended December 31, 2005, we purchased $3,227,199 of product inventory from Angiotech, and
as of December 31, 2005, we owed Angiotech $2,303,969 for manufactured product inventory and royalties, which is included in accounts payable and other accrued expenses on the consolidated balance sheet. During the year ended December 31,
2004 we purchased $164,565 of product inventory from Angiotech. All product royalty expense payable to Angiotech is included in cost of sales on the consolidated statements of operations, as we recognize product sales revenue from our customers.
