FORWARD LOOKING INFORMATION

In addition to historical facts or statements of current conditions, our disclosure and analysis in this Form 10-K contain some forward-looking statements.
Forward-looking statements provide 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. In particular, these include statements relating to present or anticipated products and markets, future revenues, capital expenditures, future financing and liquidity,
adding direct sales representatives, the adequacy of available resources, sales growth, uses of cash, adequacy and valuation of inventory, and other statements regarding matters that are not historical facts or statements of current condition.

Any or all of our forward-looking statements in this Form 10-K may turn out to be incorrect. They can be affected by inaccurate or erroneous 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, demand and market acceptance of our products, and the other risk factors addressed in Item 1A. Risk Factors. 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 Securities and Exchange Commission (SEC). This discussion is provided as permitted by the Private Securities
Litigation Reform Act of 1995.

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 biomaterials company with proprietary technologies for the development and commercialization of synthetic, biologically active,
tissue engineering products for orthopedic and neurosurgical applications. Our products are used in the regeneration of bone. Our near-term commercial business is based on our internally developed VITOSS® Bone Graft Substitute technology platform, which is designed to address the
non-structural bone graft market by offering synthetic alternatives to the use of autograft or cadaver-derived bone material to meet a broad range of orthopedic clinical needs in the spine, trauma, joint reconstruction, revision surgery and
extremities markets, 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® Synthetic Cortical Bone technology platform, which is
designed for injections into osteoporotic spines to treat vertebral compression fractures (VCFs). We have agreements with Kensey Nash Corporation (Kensey) and Angiotech Pharmaceuticals, Inc. (Angiotech) (a
shareholder of the company), that allow us to develop and market other synthetic-based biomaterial products, and continue to

##### Table of Contents

pursue similar relationships with other companies in biomaterials. 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.

In March 2003, we entered into a development, manufacturing
and supply agreement with Kensey to jointly develop and commercialize new 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 jointly developed approved or cleared product for seven years from first commercial sale of the co-developed
product and we will market and sell the product worldwide. In February 2005, the first agreement, under which the VITOSS FOAM products have been commercialized, was extended until 2014. 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 products. 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. In February 2005, we
expanded our existing relationship with Kensey and agreed to pursue co-development of soft tissue repair products for orthopedics. Similar to the terms of the original agreement signed in March 2003, Kensey will manufacture the new co-developed soft
tissue products and we will market and sell the products worldwide, with Kensey receiving a royalty on the net sales.

In June 2004, we entered into an
agreement with Cohesion Technologies, Inc., a wholly-owned subsidiary of Angiotech, to distribute, market and sell CoStasis®(which we re-branded as VITAGEL Surgical Hemostat), a composite liquid hemostat, and the CELLPAKER®plasma collection system, used together with VITAGEL, to surgical customers throughout North America, with an option to expand the
VITAGEL territory to include the European Union (EU) and the rest of the world. Under the agreement, we have obligations to purchase the products and make royalty payments to Angiotech based on the net sales of such products. Effective
September 30, 2005, we entered into an amendment to the agreement necessary to transition the manufacture of the products and accessories from Angiotech to us. In addition, the amendment changes the royalty rate payable by us to Angiotech and
modifies the method for calculating net sales of such products manufactured by Angiotech for us during the transition period. Angiotech decided to cease to manufacture VITAGEL by November 2005; therefore, in October 2005, we purchased all available
existing products, accessories and work-in-process from Angiotech for $1,800,000, which is expected to be sufficient to meet our operating requirements through mid 2006. Additionally, on November 30, 2005, we submitted a Duplicate PMA for
VITAGEL to the FDA through a Grant of License from Angiotech to reference their PMA. FDA approval of the PMA submitted by us, if obtained, will allow us to sell VITAGEL product that is manufactured on-site in our Malvern, Pennsylvania facility. As
of December 31, 2005, we had included in inventory VITAGEL valued at $653,835 that was manufactured on-site at our Malvern facility. We have no assurance that we will obtain FDA approval to sell VITAGEL manufactured by us prior to our current supply
of VITAGEL being exhausted. We may not have sufficient inventory of VITAGEL during the second half of 2006 to support customer demand.

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 Bone Graft Substitute. 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
will market and sell the combined product in the dental, periodontal, oral and cranio-maxillofacial bone grafting markets.

We market and sell our VITOSS
Bone Graft Substitute products, the IMBIBE®Bone Marrow Aspirate and Delivery Devices
(used with VITOSS Bone Graft Substitute) and VITAGEL products through a U.S. field sales network of direct sales representatives and independent sales agencies that we began to assemble in June 2003.

##### Table of Contents

As of December 31, 2005, we had approximately 50 direct sales representatives and arrangements with approximately 40 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 under served. Outside of the U.S., we primarily utilize a network of independent, stocking distributors to market VITOSS Bone Graft Substitute, CORTOSS Synthetic Cortical Bone and ALIQUOT®Micro Delivery System (a system designed to facilitate effective delivery of our CORTOSS Synthetic Cortical Bone product).

Information regarding our product sales by geographic markets for the years ended December 31, 2005, 2004 and 2003 are included in Note 11 (Product
Sales) to the consolidated financial statements, which is included elsewhere in our report on Form 10-K.

We market and sell our products for only the
indication(s) or use(s) that have received regulatory approval or clearance.

Our principal executive offices are located at 45 Great Valley Parkway,
Malvern, Pennsylvania 19355, and our telephone number is (610) 640-1775. We maintain a website at www.orthovita.com and make available free of charge on this website our annual reports on Form 10-K, quarterly reports on Form 10-Q, current
reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, as soon as reasonably practicable after we electronically file these materials with,
or furnish them to, the SEC. The reference to our website is intended to be an inactive textual reference only.

OUR PRODUCTS AND PRODUCT CANDIDATES

As further discussed below under the caption Government Regulation, our products and product candidates are subject to extensive regulation
as medical devices by the FDA, regulatory authorities in Europe and regulatory authorities in other jurisdictions. In the EU, we have selected TNO, or The Netherlands Organization for Applied Scientific Research, as our notified body (our
Notified Body) under the Medical Devices Directive (MDD). Product approval or clearance applications for our products must be supported by valid scientific evidence, and may require clinical trial data, to demonstrate the
safety and effectiveness of the products.

VITOSS Bone Graft Substitute 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 Bone Graft Substitute in the U.S. and the EU in 2001 and have sold over 98,000 units through December 31, 2005. VITOSS Bone Graft
Substitutes ultra-porosity allows it to soak and hold 90% of 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 Bone Graft Substitute integrates well into existing bone and promotes new bone in-growth and maturation. 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 Bone Graft Substitute 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 Bone Graft Substitute 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 90% of its 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.

Bone Defect Grafting. Injury or trauma to the bone, as well as degenerative conditions, disease and aging, 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 700,000 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, or (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 Bone Graft Substitute), cells or signals (such as bone morphogenic proteins). VITOSS Bone Graft Substitute 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 long bone, extremity, spine and pelvic areas.

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 Bone Graft Substitute instead of autograft material may avoid these potential complications.

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 Bone Graft Substitute, rather than allograft or autograft materials, in spinal grafting procedures may be preferable for both the
patient and the surgeon.

Iliac Crest Repair. The bone grafting material used to pack certain implants and cages used in spinal fusion procedure is
often autograft material, obtained or harvested from the iliac crest region of the patients own hip through an operating procedure. This procedure leaves an open space in the iliac crest, which is often painful and slow healing. We
estimate that each year, autograft material is used in approximately 200,000 spinal fusion procedures worldwide and that harvested material is used in another 100,000 non-spinal fusion related procedures worldwide. VITOSS Bone Graft Substitute can
be used to repair the bone void left by the harvest procedure at the time of surgery and may reduce the incidence of post-operative bleeding and post-operative pain at the harvest site and speed healing time. In post-marketing studies of VITOSS Bone
Graft Substitute for iliac crest repair, initial results suggested the use of VITOSS Bone Graft Substitute performs well in the formation of new bone.

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 Bone Graft Substitute, are used for trauma related
bone graft repairs. VITOSS Bone Graft Substitute has been used as a bone graft substitute in a variety of trauma applications, including those of the long bone, extremity, and pelvis, as well as to fill bone void defects due to trauma in fractures
of the wrist, ankle, tibia and femur.

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 proprietary VITOMATRIX particulate synthetic scaffold biomaterial, which we produce in the same process used to manufacture VITOSS Bone Graft Substitute. Under the
agreement, we will supply our proprietary beta tricalcium phosphate biomaterial to BioMimetic for its clinical and commercial use in conjunction with rhPDGF. The agreement provides that, upon obtaining the requisite regulatory approvals, which were
received during 2005, BioMimetic will market and sell 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 Bone Graft Substitute, and delivering the mixture to the bone graft site. We believe IMBIBE, when used together with VITOSS Bone Graft Substitute, 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. Our agreement with Angiotech also includes options for us to distribute VITAGEL at a future date in Europe and the rest of the world. In
January 2005, we rebranded CoStasis as VITAGEL Surgical Hemostat with CELLPAKER accessories, and relaunched the product within our existing orthopedics and spine-based distribution channel, utilizing the same marketing strategy that we use for all
of our VITOSS-related products. We believe this strategy will provide our sales network additional functional biomaterial products to offer to their customers.

Near-Term Product Development

We have developed and are continuing to develop new products under our approved VITOSS Bone Graft Substitute,
VITAGEL Surgical Hemostat and IMBIBE product platforms. We launched VITOSS Cancellous Chips and the VITAGEL Spray Set during the first half of 2006, and during the latter part of 2006, we plan to launch ORTHOVITA Cortico-Cancellous Chips. We are
seeking to bring VITOSS Bone Graft Substitute and/or IMBIBE product line extensions to market in the U.S. through the 510(k) regulatory process (see Government Regulation below). These product line extensions will be in addition to our long-term
U.S. CORTOSS investigational device exemption (IDE) clinical program, which is described below.

CORTOSS Synthetic Cortical Bone

CORTOSS Synthetic Cortical Bone is a high-strength, self-setting composite engineered specifically to mimic the characteristics of human cortical bone. Laboratory tests demonstrate that CORTOSS exhibits compressive
strength similar to human cortical 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 provide mobility to the patient as quickly as possible since prolonged bed rest or inactivity may result in decreased overall health for older or osteoporotic patients.

CORTOSS Synthetic Cortical Bone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 the CE Certification for CORTOSS Synthetic Cortical Bone 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 4,600 units of CORTOSS through December 31, 2005.

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. 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 300 patient prospective, randomized control 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 polymethylmethacrylate (PMMA) bone cement instead of a non-treatment arm consisting of conservative care and pain management. In November 2005, the study design was further amended and approved by the FDA to lower the waiting
period from six to four weeks for patients experiencing pain before enrolling in our clinical study and to allow for an exception to this criterion if the treating surgeon has determined that the patient has experienced a progression of vertebral
collapse that exceeds 5%. We do not expect to receive FDA approval for the sale of CORTOSS in the U.S. for at least the next couple of years, if at all.

Vertebral Augmentation of VCFs. We estimate there are approximately 700,000 patients worldwide 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, CORTOSS does not release free unreacted monomers, which are very volatile, into the patients body like PMMA. 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. We believe about 1,000,000 of these involve long bone fractures that are treated with metal plates and screws and the
remainder of these procedures involve hip fractures treated with compression screws and spinal fractures treated with pedicle 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.

Long Bone Screw Augmentation. In long bone
fractures, screws are placed into the plate and serve to compress the fracture, permitting faster healing. We estimate these screws strip or fail to hold in approximately 150,000



10

##### Table of Contents

osteoporotic patients each year due to poor bone quality, as is often the case in 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, (ii) replacing the plate with a longer plate with more
screw holes to span the failed screw holes, which adds considerable time to the procedure, creates a larger wound area, increases the risk of other screws failing due to their removal and reimplantation, and in certain situations is anatomically not
possible, (iii) leaving the plate with the failed screws as it is and giving the patient a non-load bearing cast for a prolonged period of time, which increases the risk of post-operative complications related to immobilization, such as deep
venous thrombosis, or (iv) augmenting the screws with PMMA bone cement, which is cumbersome and time consuming because it needs to be manually mixed and transferred into a syringe for application and, after mixing there is only a small time
window in which it 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 this indication. We believe the use of CORTOSS Synthetic
Cortical Bone 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 this indication.

A 37-patient multi-center clinical study in Europe of patients undergoing surgery to repair bone fractures demonstrated that
CORTOSS Synthetic Cortical Bone enabled the successful use of metal screws in the repair procedures despite patients poor bone quality. The three-month study showed CORTOSS restored the holding power of 98 percent of previously failed bone
screws, permitting the use of a plate to stabilize the fracture and healing in all 37 patients with no adverse events related to CORTOSS reported.

Pedicle Screw Augmentation. Many spinal surgeries today have become possible only due to the availability of instrumentation systems that allow manipulation and fixation of the individual elements of the spine. These instrumentation
systems are attached to the spine by means of screws placed in the pedicle region of the vertebrae. In patients with sub-optimal bone quality, such as osteoporotic patients, the purchase or bite of these screws may be insufficient to
maintain the integrity of the construction. We estimate there are approximately 280,000 patients who have pedicle screws implanted each year on a worldwide basis. We believe approximately 35,000 may require the augmentation of screws due to
osteoporosis. We believe CORTOSS Synthetic Cortical Bone has the potential to ensure secure fixation of the screws, enabling the instrumentation systems to restore maximum possible fixation and stabilization of the spine. Additionally, we believe
CORTOSSs mix-on-demand delivery system makes its use here convenient and practical. We are not aware of any products approved for this indication that would be in competition with CORTOSS.

Compression Screw Augmentation. We estimate approximately 750,000 hip fractures occur annually worldwide of which an estimated 250,000 are repaired using
compression screw augmentation. Many osteoporotic patients, particularly elderly women, suffer a fracture of the hip whereby the ball of the hip-and-socket, or the head of the femur leg bone, is separated from the rest of the bone. These
fractures are often treated through the use of compression hip screws, which are placed through the femur bone and into the femoral head to stabilize and compress the fracture to permit healing. The healing of a fracture is directly proportional to
the degree of stabilization. The failure of screws to hold is common, especially in osteoporotic bone. Additionally in many cases, even after the screw gains initial hold, once the patient becomes mobile, the screws sharp thread edges may
cause the screw to cut through the bone and walk-out through the femoral head. Such a failure during or after the surgical procedure will result in the need for an artificial hip implant. We believe the use of CORTOSS Synthetic Cortical
Bone to anchor the screw in a quick and efficient way will enable the full function of the screw to be restored. We are not aware of any products approved for this indication that would be in competition with CORTOSS.

In two separate clinical studies in Europe, CORTOSS Synthetic Cortical Bone was used to increase the holding power of screws in the bone and to protect the bone from the
screws sharp threads. The first study included 25

patients with subtrochanteric fractures, which had been treated with dynamic hip screws, and was completed during early 2002. None of the augmented screws
showed movement and the holding power of the screw was shown to increase significantly in all patients. This holding power was evidenced by an increase in torque resistance. A second clinical study was completed, which included 21 patients with
intra-capsular fractures of the hip, and evaluated the effect of CORTOSS for the augmentation of two parallel screws used to reduce and fix the hip fracture. We believe the use of CORTOSS for this indication has the potential to reduce the need for
a second corrective surgery.

ALIQUOT Micro Delivery System

Our ALIQUOT Micro Delivery System facilitates effective delivery of our CORTOSS Synthetic Cortical Bone product directly to the surgical site. A two-part system of catheter and syringe dispenser is designed to assure effective delivery of
CORTOSS 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 is being used in the U.S. clinical studies for CORTOSS in vertebral augmentation of VCFs. ALIQUOT is covered by U.S. issued patents.

ENDOSKELETONTA and Structural
Devices

In the first quarter of 2004, we received 510(k) regulatory clearance for ENDOSKELETON TA Vertebral Body Replacement structural device,
which provides physiological support to, or replaces damaged vertebral bodies and commenced limited sales during the second quarter of 2004.

In addition
to ENDOSKELETON TA, we plan to co-develop a structural resorbable device which we anticipate may be used in conjunction with our non-structural bone graft substitute materials, such as our VITOSS FOAM products. This product, if approvable under a
510(k), is not expected to be launched any earlier than 2007. We believe a structural device will allow us to continue to expand our reach into new markets and new clinical indications.

SIGNIFICANT CONTRACTUAL OBLIGATIONS

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

OUR RESEARCH & DEVELOPMENT

We employ composite engineering, polymer science, solution chemistry and nanoparticulate ceramic glass science to create our biomaterials technology platforms. We then
utilize biomaterials, those developed on our own and jointly with Kensey, to develop, synthetic, biologically-active products engineered to restore the human skeleton. 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 $7,167,000, $5,657,000 and $4,831,000 in research and development expenses in 2005,
2004 and 2003, 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

##### Table of Contents

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, thirteen 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, 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 and requirements, and EU MDD International Organization for Standardization (ISO) 9000 Series standards and equivalent requirements.

Our 24,800 square foot VITOSS Bone Graft Substitute and CORTOSS manufacturing facilities which produce our commercial products, are leased through July 2012 and are
certified as meeting the requirements of ISO 9000: 2000 for the period March 22, 2004 through March 22, 2007, and European Norm (EN) 13485 for the period July 1, 2003 through July 1, 2006. These facilities are subject
to inspection by the FDA for compliance with FDA device manufacture requirements. The most recent FDA inspection resulted in no corrective actions being required.

We believe our manufacturing facilities have the capacity to meet our commercial needs for the next several years. We are manufacturing VITAGEL, CELLPAKER, IMBIBE, ENDOSKELETON TA, and ALIQUOT through outside third-party contract
manufacturers. Our VITOSS Bone Graft Substitute is converted to VITOSS FOAM by Kensey, our development partner under a long term supply agreement. Our third-party manufacturers are ISO 9001 certified or otherwise meet our quality system requirements
(See GOVERNMENT REGULATION below). In addition to the need for CORTOSS U.S. regulatory approval in order to commercialize CORTOSS in the U.S., the CORTOSS manufacturing facility and quality assurance system must pass inspection by the
FDA. Angiotech decided to cease to manufacture VITAGEL by November 2005; therefore, in October 2005, we purchased all available existing products, accessories and work-in-process from Angiotech for $1,800,000, which is expected to be sufficient to
meet our operating requirements through mid 2006. Additionally, on November 30, 2005, we submitted a Duplicate PMA for VITAGEL to the FDA through a Grant of License from Angiotech to reference their PMA. FDA approval of the PMA submitted by us,
if obtained, will allow us to sell VITAGEL product that is manufactured on-site in our Malvern, Pennsylvania facility. As of December 31, 2005, we had included in inventory VITAGEL valued at $653,835 that was manufactured on-site at our Malvern
facility. We have no assurance that we will obtain FDA approval to sell VITAGEL manufactured by us prior to our current supply of VITAGEL being exhausted. We may not have sufficient inventory of VITAGEL during the second half of 2006 to support
customer demand.

Our ability to manufacture our products is dependent on a limited number of specialty suppliers of certain raw materials. We have a
long-term supply agreement which provides bovine collagen for the manufacture of VITAGEL; however, we do not have any other long-term 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, 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 Bone Graft Substitute, 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 Operations  Revenue Interests.

SALES AND MARKETING

In June 2003, we began to assemble a U.S. field sales network of direct sales representatives and independent sales agencies in order to market VITOSS Bone Graft Substitute, VITAGEL and IMBIBE Bone Marrow Aspirate and Delivery Device. 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 under served. Outside of
the U.S., we primarily utilize a network of independent, stocking distributors to market VITOSS Bone Graft Substitute, CORTOSS, and ALIQUOT Micro Delivery System.

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 Bone Graft
Substitute faces competition from numerous synthetic and cadaver-based products currently on the market as well as other products and technologies that may enter the market in the future.

In 2004, total disk replacement devices (TDRs) were introduced in the spinal market as a treatment alternative for degenerative disk disease designed to preserve
the motion of the vertebrae of the spine. We believe that several factors mitigate against the broad use of TDRs, 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 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 a CE Certification for use in the vertebral augmentation of VCFs and in screw augmentation. If CORTOSS
is approved by the FDA for use in the 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. To
date, we have received 510(k) regulatory clearance, as described below, for VITOSS Bone Graft Substitute in the U.S. from the FDA in December 2000 and the CE Certification in the EU from our Notified Body in July 2000. In March 2001, we also
received regulatory approval to sell VITOSS Bone Graft Substitute in Australia, and in June 2004, we received regulatory approval to sell VITOSS Bone Graft Substitute in Canada. 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 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, 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.

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.

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. 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 300 patient prospective, randomized control 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 November 2005, the study design was further amended and approved by the
FDA to lower the waiting period from six to four weeks for patients experiencing pain before enrolling in our clinical study and to allow for an exception to this criterion if the treating surgeon has determined that the patient has experienced a
progression of vertebral collapse that exceeds 5%. We do not expect to receive FDA approval for the sale of CORTOSS in the U.S. for at least the next couple of years, if at all.

In December 2003, we received 510(k) regulatory clearance for our ENDOSKELETON TA product platform in the U.S. from the FDA.

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.

##### Table of Contents

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

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

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

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

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

During the PMA review
period, an advisory committee, typically a panel of clinicians, will likely be convened to review and evaluate the application and provide recommendations to the FDA as to whether the device should be approved. The FDA is not bound by the
recommendations of the advisory panel. Toward the end of the PMA review process, the FDA generally will conduct an inspection of the manufacturers facilities to ensure that they are in compliance with Quality System Regulation
(QSR) requirements.

If the FDAs evaluations of both the PMA and the manufacturing facilities are favorable, the FDA will either issue an
approval letter or an approvable letter, which usually contains a number of conditions that must be met in order to secure final approval of the PMA. When, and if, those conditions have been fulfilled to the satisfaction of the FDA, the
agency will issue an approval letter, authorizing commercial marketing of the device for certain indications. If the FDAs evaluation of the PMA or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue a
not approvable letter. The FDA may also determine that

additional clinical trials are necessary, in which case PMA approval may be delayed up to several years while we conduct additional clinical trials and
submit an amendment to the PMA. The PMA process can be expensive, uncertain and lengthy, and a number of devices for which other companies have sought FDA approval have never been approved for marketing.

Modifications to a device that is the subject of an approved PMA (including modifications to its labeling or manufacturing process) may require approval by the FDA of
PMA supplements or new PMAs. 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, but not the FDA. For significant risk
devices, we must submit an IDE supplement to the FDA and receive approval from the FDA before we, or our investigator, may make a change to the investigational plan that may affect its scientific soundness or the rights, safety or welfare of human
subjects. IRB approval may be required for changes in the investigational plan for both non-significant risk and significant risk devices.

Any products
manufactured or distributed by us pursuant to FDA clearances or approvals are subject to extensive regulation by the FDA, including reporting and record keeping requirements. Device manufacturers are required to register their establishments and
list their devices with the FDA and certain state agencies, and are subject to periodic inspections by the FDA and certain state agencies. The most recent FDA inspection resulted with no corrective actions being required. The FFD&C Act requires
devices to be manufactured in accordance with Quality System Regulation 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 the ISO 9001: 2000 and EN 13485 standards for 2003). We are certified as meeting the requirements of ISO 9001: 2000
for the period March 23, 2004 through March 22, 2007, and EN 13485 for the period July 1, 2003 through July 1, 2006. 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 and IIa. 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 will be required to report any serious adverse incidents to the appropriate authorities. We also will be required to comply with additional national requirements that are beyond the scope of the MDD. There can be no assurance that
we will not be required to incur significant costs to comply with such laws and regulations now or in the future or that such laws or regulations will not have a material adverse effect upon our ability to do business.

THIRD-PARTY REIMBURSEMENT

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

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

Medicare provides, among other things, health care benefits that cover, within prescribed limits, the
major costs of most medically necessary care for such individuals, subject to certain deductibles and co-payments. The Medicare program has established, and continues to establish, standards and guidelines for the coverage and



18

##### Table of Contents

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 the Companys 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 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. 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,



19

##### Table of Contents

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 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.

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 one product liability claim to date, which we have successfully defended. There can be no assurance that other product liability claims will not be asserted against us in the future. Under certain of
our agreements with our independent sales agencies and stocking distributors, we provide indemnification



20

##### Table of Contents

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, 2005, we had 140 full-time
employees, with 73 employees at our Malvern, Pennsylvania headquarters, 61 employees throughout the U.S. and 6 employees in Europe. We consider our relations with our employees to be good.



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

If VITOSS is not commercially successful in the
United States or if CORTOSS and VITOSS are not commercially successful in the European Union, our operating results will be impaired.

We are highly
dependent on successfully selling our products for which we have received regulatory approval or clearance. We expect regulatory approvals or clearances in the United States for our products under development, if obtained at all, to take several
years. To date, we have received regulatory 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 to market VITOSS and IMBIBE in the United States. For these reasons, we are dependent upon VITOSS and CORTOSS and their ancillary products, IMBIBE and ALIQUOT, in their respective approved markets to generate sufficient revenues to sustain
operations in the future.

These products have only been recently approved or cleared and launched, and the markets for our products are evolving.
Accordingly, we cannot accurately predict either the future growth rate of product sales, if any, or the ultimate size of these markets. Certain factors that may limit our ability to increase sales include:



| |  |  | 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 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 new technologies that have not been previously used 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



21



---

##### Table of Contents

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.

Our plan to assume manufacturing of VITAGEL and its related products may not be successful or timely.

Pursuant to our Exclusive Sales Distribution Agreement with Angiotech, as amended, we expect to assume full manufacturing for the VITAGEL product upon approval from the
FDA of the PMA we submitted in December 2005. There can be no assurance that we will receive FDA approval to manufacture VITAGEL or that, even if approved, we will be able to comply with FDA regulatory requirements to continue to manufacture
VITAGEL, which could result in delay or inability to manufacture and sell the products. There can be no assurance that we will receive any such approval prior to running out of the limited product we purchased to sell that was manufactured by
Angiotech prior to their shutting down their manufacturing facility in November 2005.

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 Bone Graft Substitute, VITAGEL and IMBIBE. Outside of the U.S., we utilize a network of independent stocking distributors to market VITOSS Bone Graft Substitute, 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 Bone Graft Substitute generally sell
products from other orthopedic companies. A single agency may sell VITOSS Bone Graft Substitute, 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 Bone Graft Substitute as a result of the introduction of new products into the market based upon other technologies that could compete with VITOSS Bone Graft Substitute. Our sales could be adversely affected if one or more of
our successful agencies eliminated VITOSS Bone Graft Substitute 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 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.

##### Table of Contents

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.

The unapproved or
off-label use of our products could adversely affect the reputation of our products.

The medical devices that we manufacture and market, or
intend to market, are subject to extensive regulation by the FDA, the European Union Medical Devices 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, 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 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 since
the European Union only recently approved the use of CORTOSS for that type of procedure. 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.

##### Table of Contents

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 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 may need 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 may 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;

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.

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 Bone Graft Substitute 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 end
of 2006. During 2004, we received approval from the FDA to conduct a pivotal clinical study in the U.S. to further study the use of CORTOSS in vertebral augmentation using the vertebroplasty surgical technique. We are still in the process of
completing enrollment of the pivotal clinical study. There can be no assurance that the data from these clinical trials will support FDA clearance or approval to market this product for the designated use.

We are currently manufacturing VITOSS Bone Graft Substitute and CORTOSS in the U.S., distributing VITOSS Bone Graft Substitute, VITAGEL and IMBIBE in the U.S., and
distributing VITOSS Bone Graft

##### Table of Contents

Substitute, 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, Kensey has the exclusive right to manufacture any approved or cleared jointly developed products under the agreement, including the VITOSS FOAM product platform. In March 2005, the initial term of the agreement was
extended by amendment for an additional three years to 2014. VITAGEL and CELLPAKER will be manufactured by us following FDA approval.

VITOSS Bone Graft
Substitute, as well as any other products that we manufacture or distribute following their approval or clearance by the FDA, including VITAGEL if we are approved as a manufacturer, 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.

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 Certification, an international symbol of adherence to quality assurance standards and compliance with applicable European medical
device directives. A CE Certification enables us to market a product in all of the countries of the European Union, as well as in other countries, such as Switzerland and Israel, that have adopted the European Unions regulatory standards. To
date, we have received a CE Certification for the use of VITOSS Bone Graft Substitute 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.

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.

Our VITOSS Bone Graft Substitute and CORTOSS Synthetic Cortical Bone manufacturing facilities produce commercial products and are currently certified as meeting the requirements of ISO 9001: 2000 for the period
March 23, 2004 through March 22, 2007 and European Norm 13485 for the period July 1, 2003 through July 1, 2006, and are subject to inspection by the FDA for compliance with FDA device manufacture requirements. In addition to the
need for regulatory approval in the U.S. for CORTOSS, in order to commercialize CORTOSS in the U.S., its manufacturing facility and quality assurance system must first pass inspection by the FDA. On November 30, 2005, we submitted a Duplicate
PMA for VITAGEL to the FDA through a Grant of License from Angiotech to reference their PMA. FDA approval of the PMA submitted by us, if obtained, will allow us to sell VITAGEL product that is manufactured on-site in our Malvern, Pennsylvania
facility. As of December 31, 2005, we had included in inventory VITAGEL valued at $653,835 that was manufactured on-site at our Malvern facility. We have no

##### Table of Contents

assurance that we will obtain FDA approval to sell VITAGEL manufactured by us prior to our current supply of VITAGEL being exhausted. We may not have
sufficient inventory of VITAGEL during the second half of 2006 to support customer demand.

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 our manufacture of products;
|- |  | ---------------------------------------------------



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



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



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



| |  | total or partial suspensions of production.
|- |  | -------------------------------------------

We are dependent on a
limited number of specialty suppliers of certain raw materials.

Our ability to manufacture VITOSS Bone Graft Substitute and CORTOSS and to have VITOSS
FOAM and VITAGEL manufactured for us is dependent on a limited number of specialty suppliers of certain 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, 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 Bone Graft Substitute, 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, there can be no guarantee that such
supplies and services will continue to be available with respect to our current and future commercialized products.

We are dependent on Kensey and
other third-party manufacturers for the supply of products that we may sell.

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 MDD International Organization for Standardization (ISO) 9000 Series standards and equivalent requirements.

Our 24,800 square foot VITOSS Bone Graft Substitute and CORTOSS manufacturing facilities which produce our commercial products, are leased through July
2012 and are certified as meeting the requirements of ISO 9000: 2000 for the period March 22, 2004 through March 22, 2007, and European Norm (EN) 13485 for the period July 1, 2003 through July 1, 2006. These
facilities are subject to inspection by the FDA for compliance with FDA device manufacture requirements. The most recent FDA inspection resulted with no corrective actions being required.

We believe our manufacturing facilities have the capacity to meet our commercial needs for the next several years. We are
manufacturing VITAGEL, CELLPAKER, IMBIBE, ENDOSKELETON TA, and ALIQUOT through outside third-party contract manufacturers. Our VITOSS Bone Graft Substitute is converted to VITOSS FOAM by Kensey, our development partner. Our third-party manufacturers
are ISO 9001 certified or otherwise meet our quality system requirements. In addition to the need for CORTOSS U.S. regulatory approval in order to commercialize CORTOSS in the U.S., the CORTOSS manufacturing facility and quality assurance system
must pass inspection by the FDA. Angiotech decided to cease to manufacture VITAGEL by November 2005; therefore, in October 2005, we purchased all available existing products, accessories and work-in-process from Angiotech for $1,800,000, which is
expected to be sufficient to meet our operating requirements through mid 2006. Additionally, on November 30, 2005, we submitted a Duplicate PMA for VITAGEL to the FDA through a Grant of License from Angiotech to reference their PMA. FDA
approval of the PMA submitted by us, if obtained, will allow us to sell VITAGEL product that is manufactured on-site in our Malvern, Pennsylvania facility. As of December 31, 2005, we had included in inventory VITAGEL valued at $653,835 that was
manufactured on-site at our Malvern facility. We have no assurance that we will obtain FDA approval to sell VITAGEL manufactured by us prior to our current supply of VITAGEL being exhausted. We may not have sufficient inventory of VITAGEL during the
second half of 2006 to support customer demand.

Our ability to manufacture our products is dependent on a limited number of specialty suppliers of certain
raw materials. We have a long-term supply agreement which provides bovine collagen for the manufacture of VITAGEL; however, we do not have any other long-term 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, 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 Bone Graft Substitute, CORTOSS and certain products that we may develop in the future may result in a breach of our material financing agreement with Royalty Trust.

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

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;
|- |  | ----------------------------------------

##### Table of Contents

| |  | 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 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 $24.0 million in net proceeds from the sale of 5,681,818 shares of our Common Stock to Angiotech and, in
December 2005, we raised an aggregate of approximately $12.9 million in net proceeds from the sale of 4,318,182 shares of our Common Stock to institutional investors. We believe our existing cash, cash equivalents, and investments of $27,672,221 as
of December 31, 2005 will be sufficient to meet our currently estimated operating and investing requirements for at least the next twelve months. To date, we have not been profitable. We have incurred substantial operating losses since our
inception and at December 31, 2005, had an accumulated deficit of $118,574,135. 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 products may never be commercially accepted or generate sufficient product sales to fund operations.

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 provides for Royalty Trust to receive 3.5% on the first $100,000,000 of annual sales plus 1.75% of annual sales in excess of $100,000,000 of certain of our products, including VITOSS, CORTOSS and any structural bioactive device
developed, in North America and Europe through 2016, subject to certain adjustments. This revenue interest percentage can increase 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. 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. In January 2004, the revenue interest assignment agreement with Royalty Trust was amended by mutual agreement to reduce the advance payment for 2004
from $2,000,000 to $1,100,000. Of the $1,100,000 paid to Royalty Trust, $837,844 was earned in 2004 and the balance of $262,154 was included in prepaid revenue interest expense on the accompanying consolidated balance sheet as of December 31,
2004, and was repaid to us during the first quarter of 2005. In

##### Table of Contents

February 2005, the revenue interest assignment 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, $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 is scheduled to be repaid to us in April of 2006. In December 2005, the revenue interest assignment 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. The amount of the advance payment remains $3,000,000 in each of the years 2007 through 2016. While we believe that we will have sufficient cash at the end of 2006 to make the required $3,000,000 advance
payments to Royalty Trust during 2007, we cannot be certain that we will have sufficient cash to meet our advance payment obligations for the years 2008 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 Bone Graft
Substitute, CORTOSS and any structural bioactive device developed, in North America and Europe, and the 12% revenue interest we pay to one of our wholly-owned subsidiaries, on the sales of our products (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, 2005, we were in compliance with all financial covenants. 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 Bone Graft Substitute, 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



30

##### Table of Contents

triggered and Royalty Trust exercised its right to require us to repurchase its revenue interest as of December 31, 2005, we would have owed Royalty
Trust $19,606,958.

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 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, 2005.
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 Bone Graft Substitute, IMBIBE, CORTOSS and ALIQUOT are currently our only products for which we have received regulatory approvals for sale. VITOSS Bone Graft
Substitute is cleared for sale in the U.S. and the European Union. IMBIBE is cleared for sale in the U.S. CORTOSS and ALIQUOT are cleared for sale in the European Union. In addition, we obtained distribution rights to VITAGEL and CELLPAKER in June
2004 and launched that product in the U.S. in January 2005. Future levels of VITOSS Bone Graft Substitute, VITAGEL, CORTOSS, ALIQUOT, CELLPAKER and IMBIBE product sales are difficult to predict. VITOSS Bone Graft Substitute product sales to date may
not be indicative of future sales levels. VITOSS Bone Graft Substitute, 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 Bone Graft
Substitute, 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 December 31, 2005, we own or control eighteen issued U.S. patents and thirteen 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

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

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.

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, several PMMA bone cement received 510(k) clearance in 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 disk 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;
|- |  | -----------------------------------------



| |  | experience in regulatory matters;

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



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



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

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

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 20,000,000 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:

common stock. The following factors could also cause our stock price to be volatile or decrease:

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 and sales agencies, we indemnify the distributor or sales agency 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 million, 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.

|ITEM 7. | MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
|------- | -------------------------------------------------------------------------------------

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. In
particular, these include statements relating to present or anticipated products and markets, future revenues, capital expenditures, future financing and liquidity, adding direct sales representatives, the adequacy of available resources, sales
growth, uses of cash, adequacy and valuation of inventory, and other statements regarding matters that are not historical facts or statements of current condition. Any or all of our forward-looking statements in this Form 10-K may turn out to be
incorrect. They can be affected by inaccurate or erroneous 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. 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 SEC. This discussion is provided as permitted by the Private
Securities Litigation Reform Act of 1995.

CRITICAL ACCOUNTING POLICIES

The preparation of financial statements requires us to make assumptions, estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses and disclosures of contingent assets
and liabilities as of the date of the financial statements. On an on-going 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. We believe the following critical accounting policies, which have been reviewed with the Audit Committee, affect our more
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. We do not allow product returns or exchanges. We have no post-shipment obligations to our customers. 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 sales discounts are not offered.

##### Table of Contents

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. For the years ended December 31, 2005 and 2004, cost of sales includes a provision of $1,606,420 and $1,590,856, respectively, to write down inventory to its estimated net realizable value prior to
the expiry date of such inventory. 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 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 Issue No. 88-18, Sales of Future Revenues (EITF 88-18). On March 22, 2002, we amended the original financing,
which resulted in a one-time increase to the revenue interest obligation of $1,945,593, increasing the balance of the revenue interest obligation to $7,167,700 as of December 31, 2005 and 2004.

The products that are subject to the revenue interest have only been approved or cleared and marketed for several years or are still under development. For these
reasons, as of December 31, 2005 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. Revenue interest expense of $989,287, $837,844 and $642,850 has been recorded for the years ended December 31, 2005, 2004 and 2003,
respectively. The revenue interest under this agreement is treated as interest expense in accordance with EITF 88-18, Sales of Future Revenues.

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 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. 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. A valuation allowance has been established against all of our deferred tax assets since, given our history
of operating losses, the realization of the deferred tax asset is not assured.

Accounting for Stock Options Issued to
Employees and Non-employees

For periods through December 31, 2005, 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 is 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. SFAS
No. 123, Accounting for Stock-Based Compensation, (SFAS No. 123) established accounting and disclosure requirements using a fair-value based method of accounting for stock-based employee compensation plans. Under
SFAS No. 123, compensation cost for the fair-value related to stock options is computed based on the value of the stock options at the date of grant using an option valuation methodology, typically the Black-Scholes model. As required by SFAS
No. 123, as amended by SFAS No. 148, Accounting for Stock-Based Compensation, we apply the SFAS No. 123 fair-value method of accounting to non-employee stock option grants. For the years ended December 31, 2005, 2004
and 2003, we recorded $146,313, $439,068, and $689,762, respectively, of expense related to SFAS No. 123 for our non-employee stock option grants. For options granted to employees, SFAS No. 123 allows a company either to record the
Black-Scholes model value of the stock options in its statement of operations or continue to record the APB No. 25 intrinsic value in its statement of operations and disclose the SFAS No. 123 fair value. For options granted to employees,
we apply the intrinsic value based method of accounting under APB No. 25, and disclose the SFAS No. 123 fair value.

In December 2004, the FASB
issued SFAS No. 123R, Share-Based Payment. This statement revises SFAS No. 123, and requires companies to expense the value of employee stock options and similar awards. The effective date of this standard is the first annual
period beginning after June 15, 2005, which is January 1, 2006 for the Company. Under SFAS No. 123R, we will be required to expense stock options in our Consolidated Statements of Operations when they are granted. The actual effect on net
loss and loss per share will vary depending upon the number of grants of options in 2006 and future periods as compared to prior years. We have selected the Black-Scholes option-pricing model, on a modified prospective transition method, as the most
appropriate fair-value method for our awards and will recognize compensation costs over the vesting periods of the awards. We expect to record approximately $1,700,000 during the year ended December 31, 2006 related to SFAS No. 123R.

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, options to purchase approximately 1,110,000 shares of our Common Stock were subject to this acceleration.
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 estimated future compensation expense that would
have otherwise been recognized in our consolidated statement of operations with respect to these options under SFAS No. 123R is approximately $5,000,000 of which the pro forma effect is included in stock-based employee compensation expense for the
year ended December 31, 2005, in Note 2 to the Consolidated Financial Statements. Had these options not been accelerated, this $5,000,000 expense would have been recorded as follows: $1,600,000 in 2006, $1,400,000 in 2007, $1,200,000 in 2008 and
$800,000 in 2009.

NET CASH USED IN OPERATING ACTIVITIES

OPERATING CASH INFLOWS

Operating cash inflows for the years ended December 31, 2005 and 2004 have been derived
primarily from VITOSS Bone Graft Substitute, IMBIBE Bone Marrow Aspirate and Delivery Device and VITAGEL Surgical Hemostat product sales in the U.S. and from VITOSS Bone Graft Substitute, CORTOSS Synthetic Cortical Bone and ALIQUOT Micro Delivery
System 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 twelve months ended December 31, 2005 have primarily been used for (i) the purchase of product inventory from Kensey Nash Corporation (Kensey) of $4,229,667, (ii) the purchase
of existing products, accessories and work-in-process from Angiotech Pharmaceuticals, Inc. (Angiotech) of $1,255,082, which we believe will be sufficient to meet our operating requirements through mid 2006; (iii) the production of
VITAGEL and CORTOSS inventory, (iv) the U.S. pivotal clinical study for Cortoss and (v) headcount additions, as we expand our field sales network and strengthen our sales management team. Additionally, operating cash outflows have
continued to be utilized for development and pre-clinical and clinical activities in preparation for regulatory filings of our products in our development pipeline.

In February 2005, the revenue interest assignment agreement with Royalty Trust was amended by mutual agreement to reduce the advance payment for 2005 from $3,000,000 to $1,600,000, which was paid to Royalty Trust
during February 2005 net of the $262,154 balance in prepaid revenue interest expense outstanding as of December 31, 2004.

We believe our existing
cash, cash equivalents and investments of $27,672,221 as of December 31, 2005 will be sufficient to meet our currently estimated operating and investing requirements for at least the next twelve months.

OPERATING CASH FLOW REQUIREMENTS OUTLOOK

We expect to focus our
efforts on sales growth under our VITOSS Bone Graft Substitute, VITAGEL Surgical Hemostat and IMBIBE product platforms for 2006. We launched VITOSS Cancellous Chips and the VITAGEL Spray Set during the first quarter of 2006, and during the latter
part of 2006, we plan to launch ORTHOVITA Cortico-Cancellous Chips. In addition, we intend to use operating cash on the collection and publication of VITOSS Bone Graft Substitute post-clinical data for marketing and sales purposes, and on continual
improvements to our distribution channels. There may be future quarterly fluctuations in spending. Prior to the launch of each new product line configuration, significant inventory levels must be manufactured. The inventory may be manufactured in
anticipation of the receipt of regulatory approval or clearance and may be initially built with one-year shelf life, so as to accelerate the commercial launch of the product, once approved or cleared, to our field sales network of independent sales
agencies and direct sales representatives. If the inventory is built in the reporting periods prior to the receipt of the required regulatory approval or clearance for new products, the cost of the inventory manufactured will be expensed in
accordance with SFAS No. 2 Accounting for Research and Development Costs. If inventory is built with one-year shelf life or our product sales fail to meet expected levels, we may experience inventory obsolescence.

In an effort to further increase sales of our new VITOSS Bone Graft Substitute product line configurations in future quarters, we intend to 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 under served.

Additionally, we expect to use cash, cash equivalents and investments for the associated marketing and sales activities with VITOSS Bone Graft Substitute, IMBIBE and VITAGEL in the U.S. and VITOSS Bone Graft
Substitute, CORTOSS and ALIQUOT outside the U.S. Additionally, we expect to continue to use cash, cash equivalents and investments during 2006 in operating activities associated with clinical trials in the U.S. for CORTOSS, research and development,
product development for our VITOSS Bone Graft Substitute and IMBIBE product line configurations and any structural device platform. We expect to incur approximately $3.5 million in external costs over the next two years in the execution of the
CORTOSS pivotal clinical study in the U.S. The timing of such expense is largely dependent upon the rate of patient enrollment in the study.

##### Table of Contents

Our operating cash flow requirements are heavily dependent upon the timing of receipt of FDA 510(k) clearance for new
product line configurations, the timing of receipt of FDA approval to manufacture VITAGEL ourselves in our manufacturing facility, the timing of inventory builds to support product launches and related inventory valuations, the timing of subsequent
launches and acceptance of our new product line configurations, 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, for 2006, our
operating cash flow requirements may still be subjected to quarterly volatility, up or down. 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.

Agreement with Kensey Nash Corporation. In March 2003, we entered into a development, manufacturing and supply agreement with
Kensey to jointly develop and commercialize new 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 jointly developed approved product for seven years from first commercial sale of the co-developed product and we will market and sell the
product worldwide. In February 2005, the first agreement, under which the VITOSS FOAM products have been commercialized, was extended until 2014. 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 products. 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. In February 2005, we expanded our existing relationship with
Kensey and agreed to pursue co-development of soft tissue repair products for orthopedics. Similar to the terms of the original agreement signed in March 2003, Kensey will manufacture the new co-developed soft tissue products and we will market and
sell the products worldwide, with Kensey receiving a royalty on the net sales. Approximately 60% of our product sales during 2005 were from products co-developed with Kensey. As of December 31, 2005, we owed Kensey $1,323,595 for manufactured
product inventory and royalties, which are included in accounts payable and other accrued expenses on the consolidated balance sheet. Amounts due to Kensey as of December 31, 2005 are expected to be paid by us during the first quarter of 2006.

Agreement with Cohesion Technologies, Inc. In June 2004, we entered into an agreement with Cohesion Technologies, Inc., a wholly-owned subsidiary
of Angiotech, to distribute, market and sell CoStasis®(which we re-branded as VITAGEL
Surgical Hemostat), a composite liquid hemostat, and the CELLPAKER®plasma collection
system, used together with VITAGEL, to surgical customers throughout North America, with an option to expand the VITAGEL territory to include the European Union (EU) and the rest of the world. Under the agreement, we have obligations to
purchase the products and make royalty payments to Angiotech based on the net sales of such products. Effective September 30, 2005, we entered into an amendment to the agreement necessary to transition the manufacture of the products and
accessories from Angiotech to us. In addition, the amendment changes the royalty rate payable by us to Angiotech and modifies the method for calculating net sales of such products manufactured by Angiotech for us during the transition period.
Angiotech decided to cease to manufacture VITAGEL by November 2005; therefore, in October 2005, we purchased all available existing products, accessories and work-in-process from Angiotech for $1,800,000, which is expected to be sufficient to meet
our operating requirements through mid 2006. Additionally, on November 30, 2005, we submitted a Duplicate PMA for VITAGEL to the FDA through a Grant of License from Angiotech to reference their PMA. FDA approval of the PMA submitted by us, if
obtained, will allow us to sell VITAGEL product that is manufactured on-site in our Malvern, Pennsylvania facility. As of December 31, 2005, we had included in inventory VITAGEL valued at $653,835 that was manufactured on-site at our Malvern
facility. We have no assurance that we will obtain FDA approval to sell VITAGEL manufactured by us prior to our current supply of VITAGEL being exhausted. We may not have sufficient inventory of VITAGEL during the second half of 2006 to support
customer demand.

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. 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.

Revenue Interest.
The revenue interest 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 Bone Graft Substitute, CORTOSS and
any structural bioactive device developed, 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 Bone Graft Substitute 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.

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 January 2004, the revenue interest assignment agreement with Royalty Trust was amended by mutual agreement to reduce the advance payment for 2004 from $2,000,000 to $1,100,000. Of the $1,100,000 paid to Royalty Trust, $837,844 was earned in
2004 and the balance of $262,154 was included in prepaid revenue interest expense on the accompanying consolidated balance sheet as of December 31, 2004, and was repaid to us during the first quarter of 2005. In February 2005, the revenue
interest assignment 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, $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 is scheduled to be repaid to us in April of 2006. In December 2005, the revenue interest assignment 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. The amount of the advance payment remains $3,000,000 in each of the years
2007 through 2016. While we believe that we will have sufficient cash at the end of 2006 to make the required $3,000,000 advance payments to Royalty Trust during 2007, we cannot be certain that we will have sufficient cash to meet our advance
payment obligations for the years 2008 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.

As of December 31, 2005, we were in compliance
with all financial covenants. 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, 2005, we would have owed Royalty Trust $19,606,958. As of December 31, 2005, we do not expect to fall out of compliance in the foreseeable future with the financial covenants of the
revenue interest obligation.

NET CASH PROVIDED BY (USED IN) INVESTING ACTIVITIES

INVESTING CASH INFLOWS

During 2005 and 2004, we received $20,915,000 and $1,998,000, respectively, from the sale of
investment grade marketable securities.

During the year ended December 31, 2004, we received $14,480 from the sale
of used laboratory equipment.

INVESTING CASH OUTFLOWS

During the years ended December 31, 2005 and 2004, $21,105,775 and $18,928,019, respectively, was used for the purchase of investment grade short-term and long-term marketable securities.

We have invested $1,470,080 and $1,424,513 for the years ended December 31, 2005 and 2004, respectively, primarily for the purchase of manufacturing equipment,
computer equipment and leasehold improvements.

INVESTING CASH OUTLOOK

We expect the amount that we spend for the purchase of leasehold improvements and capital equipment during 2006 to be less than 2005. We will seek to finance new capital investments through notes payable or capital
leases under an equipment line of credit.

NET CASH PROVIDED BY FINANCING ACTIVITIES

FINANCING CASH INFLOWS

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, 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, 2005 and 2004, we issued notes payable of $1,572,514 and $537,974, respectively, in connection with the purchase of property and equipment.

FINANCING CASH OUTFLOWS

During 2005 and 2004, $523,392 and $440,088,
respectively, were used to repay notes payable and capital lease obligations.

During the year ended December 31, 2004, we incurred additional costs
of $10,767 associated with the prior year sale of our stock.

FINANCING REQUIREMENTS OUTLOOK

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.

We do not expect sales to generate cash flow in excess of operating
expenses for at least the next two 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 $27,672,221 as of December 31, 2005, will be sufficient to meet our currently estimated operating and investing requirements for at least the next twelve months. We will seek to finance new capital investments through notes
payable 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.

Leases. We lease office space and equipment under non-cancelable operating leases.

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 months from the date of issuance for each note. The notes payable are secured by certain capital assets. During 2005, we closed on two individual notes totaling an aggregate principal amount of $1,572,514
with annual interest rates of approximately 11.19%. In addition during 2004, we closed on two individual notes totaling an aggregate principal amount of $537,974 with annual interest rates of approximately 11.43%, and during 2003, we closed on two
individual notes totaling an aggregate principal amount of $292,292 with annual interest rates of approximately 10.42%. During January 2002, we entered into a $129,472 capital lease financing arrangement with a different lending institution. The
term of this lease is 60 months with an annual interest rate of 11.45%.

RESULTS OF OPERATIONS

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

Comparison of the Year Ended December 31, 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 Bone Graft Substitute and IMBIBE. The
remaining sales, during 2005 and 2004, were a result of VITOSS Bone Graft Substitute, CORTOSS and ALIQUOT sales outside the U.S., primarily in Europe.

Gross Profit. Gross profit for the full years 2005 and 2004 was $22,027,720 and $16,902,490, respectively. As a percentage of sales, gross profit was 64% for 2005, as compared to 69% for 2004. The gross profit percentage

##### Table of Contents

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 profit percentage by 4% and 6% for the periods, respectively. The lower gross profit percentage 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 profit percentage 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 the year.

General & 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 &
administrative expenses decreased to 19% of product sales for 2005 as compared to 23% of product sales for 2004.

Selling & 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 the twelve months ended December 31, 2005 primarily due to
higher salary and benefit costs incurred by 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 & marketing expenses decreased to 61% of product sales for 2005 as compared to 74% of product sales for 2004.

Research & 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.

Comparison of the Year Ended December 31, 2004 to the Year Ended December 31, 2003

Product Sales.
Product sales for 2004 increased 59% to $24,661,382 from $15,468,621 in 2003. 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, 2004 and 2003, 93% and 92% of product
sales, respectively, were in the U.S., primarily from sales of VITOSS Bone Graft Substitute and IMBIBE. The remaining sales, during 2004 and 2003, were a result of VITOSS Bone Graft Substitute, CORTOSS and ALIQUOT sales outside the U.S., primarily
in Europe.

##### Table of Contents

Gross Profit. Gross profit for the full year 2004 and 2003 was $16,902,490 and $12,831,149, respectively. As a
percentage of sales, gross profit was 69% for 2004, as compared to 83% for 2003. The gross profit percentage for 2004 was negatively impacted by a $1,590,856 adjustment to write down inventory to its estimated net realizable value. The write down 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 $1,590,856 adjustment to write down inventory during the year ended
December 31, 2004 lowered the gross profit percentage by 6% for the period. The lower gross profit percentage for 2004 was further affected by the shift in product mix toward the VITOSS FOAM product platform, which has a lower gross profit
percentage on a higher average selling price per unit as compared to our other products.

Operating Expenses. Operating expenses for the years ended
December 31, 2004 and 2003 were $29,439,511 and $21,252,581, respectively, which represents a 39% increase as compared to a 59% increase in product sales for the year.

General & administrative expenses for 2004 increased to $5,595,049 from $4,243,108 for 2003 primarily due to consulting costs associated with Sarbanes-Oxley compliance initiatives, patent-related legal
expenses in connection with additional filings associated with our new products, and additional headcount. General & administrative expenses decreased to 23% of product sales for 2004 as compared to 27% of product sales for 2003.

Selling & marketing expenses were $18,187,113 for the year ended December 31, 2004, a 49% increase from $12,178,503 for the year ended
December 31, 2003. Selling and marketing expenses increased for the twelve months ended December 31, 2004 primarily due to higher salary and benefit costs incurred by 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 2004.
Selling & marketing expenses decreased to 74% of product sales for 2004 as compared to 79% of product sales for 2003.

Research &
development expenses increased to $5,657,349 for 2004 from $4,830,970 for 2003. The 17% increase is primarily due to development work associated with additional product configurations to be sold under our VITOSS FOAM platform and costs associated
with restarting and revalidating our CORTOSS manufacturing facility. Research & development expenses decreased to 23% of product sales for 2004 as compared to 31% of product sales during 2003. We expect research and development expenses to
increase in 2005 as a result of our CORTOSS clinical trial in the U.S.

Net other expense. Net other expense includes interest income, interest
expense and revenue interest expense. We recorded $661,003 and $580,024 of net other expense for the years ended December 31, 2004 and 2003, respectively. The increase in net other expense is primarily attributed to higher revenue interest
expense incurred under the arrangement with Royalty Trust due to higher product sales. This increase in net other expense was partially offset by higher interest income as a result of higher average cash, cash equivalent, short-term and long-term
investment balances.

Dividends on Preferred Stock. For the year ended December 31, 2003, dividends declared of $268,521 were paid in 84,281
shares of our Common Stock to holders of our Series A 6% Adjustable Cumulative Convertible Voting Preferred Stock (the Series A Preferred Stock). In addition, for the year ended December 31, 2003, we recorded $850,869 to recognize
the deemed dividend as it relates to the increasing dividend rate, which was applicable to the Series A Preferred Stock in accordance with Staff Accounting Bulletin No. 68, Increasing Rate Preferred Stock (SAB 68). There were
no dividends or deemed dividends recorded during 2004 as a result of conversion of the majority of the Series A Preferred Stock to Common Stock on June 27, 2003.

|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. The resulting translation adjustments are accumulated in a
separate component of shareholders equity. Revenues and expenses are translated at average exchange rates in effect during the period with foreign currency transaction gains and losses, if any, included in results of operations.

As of December 31, 2005, our total exposure to foreign currency risk in U.S. dollar terms was approximately $2,100,000, or 4.0%, 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 $210,000 at December 31, 2005.

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, 2005 and 2004, 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.

(a)
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, 2005. Disclosure controls and procedures are designed 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. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are
not effective as of December 31, 2005 due to the material weakness discussed in Managements Annual Report on Internal Control Over Financial Reporting below. The material weakness related to ineffective internal controls associated with
the physical count and compilation of inventory as of December 31, 2005.

(b) Managements Annual Report on
Internal Control Over Financial Reporting

MANAGEMENTS ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Orthovita, Inc. (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting as defined in
Exchange Act Rule 13a-15(f). Orthovita, Inc.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. Orthovita, Inc.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, 2005. 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. As a result of this assessment and based on the criteria in the COSO framework, management has concluded that, as of December 31, 2005, the Companys internal control over financial reporting was
not effective because of the material weakness described below.

##### Table of Contents

A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote
likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. The following material weakness has been identified as existing at December 31, 2005 and is included in managements
assessment:

The Company did not maintain effective controls over the processes associated with its year-end physical inventory count. Specifically, the
Companys policies and procedures over its year-end physical inventory count process did not provide for an appropriate level of training to adequately prepare personnel involved in the physical inventory count, and did not provide for
sufficient supervision and review by appropriate company personnel of the physical inventory count results and certain reconciliations prepared in connection with the physical inventory count. As a result of these internal control deficiencies, the
Company completed an inaccurate physical count of inventory on hand at December 31, 2005 and performed an inaccurate compilation of inventory count tags. These deficiencies resulted in a misstatement of inventory as of December 31, 2005,
which the Company corrected prior to the issuance of its 2005 financial statements. Additionally, these deficiencies could result in a material misstatement of inventory in our annual or interim consolidated financial statements. Accordingly,
management determined that these control deficiencies constitute a material weakness as of December 31, 2005. The material weakness did not affect our previously released consolidated financial information.

The Companys independent registered public accounting firm, KPMG LLP, has audited managements assessment of the Companys internal control over
financial reporting and issued its report, which appears below, on managements assessment of, and on the effective operation of, the Companys internal control over financial reporting as of December 31, 2005.

(c) Change in Internal Control Over Financial Reporting

We have begun to institute, and intend to complete during 2006, the following measures to remediate the internal control deficiencies that resulted in the identification of the material weakness in internal control
over financial reporting noted in Item 9A(b) above:



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

##### Table of Contents

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



| |  |  | Physical inventory procedures will be reviewed and additional training will be provided to counters and management prior to the taking of each physical inventory.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We are implementing within our automated inventory system controls to provide greater accuracy over physical inventory locations within our warehouse.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------

During the quarters ended September 30, 2005 and December 31, 2005, we instituted changes in our internal control over financial reporting to remediate a
material weakness previously disclosed in our Forms 10-Q for the periods ended June 30, 2005 and September 30, 2005. During the quarter ended June 30, 2005, in connection with the preparation of the consolidated financial statements,
management identified two deficiencies which are described below. These deficiencies, in managements opinion, constituted a material weakness in the Companys accounting for inventory as of June 30, 2005.



|1. | Inventory Obsolescence. The Company did not maintain effective control over the processes associated with accounting for obsolete inventory. Specifically, a computer-generated
report utilized during the June 30, 2005 quarterly closing process to determine whether inventory should be classified as obsolete was inappropriately designed, such that it failed to reflect inventory at two company sites. The use of this
report resulted initially in an understatement of the inventory reserve for the second quarter of 2005. The error was corrected by recording adjustments to the Companys consolidated financial statements prior to the public release of the
consolidated financial statements for the quarter ended June 30, 2005.
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We implemented the following measures during the quarters ended
September 30, 2005 and December 31, 2005 to remediate this matter and we tested the effectiveness of these internal controls and determined that these controls were operating effectively as of December 31, 2005:



| |  |  | We compare control totals derived from physical inventory reports addressing the value of our inventories to those totals utilized in reports used for calculating inventory
obsolescence.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | We value inventory obsolescence on a monthly, rather than quarterly basis.
| | - |  | --------------------------------------------------------------------------



| |  |  | We added two levels of financial department review with respect to our inventory obsolescence analysis.
| | - |  | -------------------------------------------------------------------------------------------------------



|2. | Overhead Cost Allocation. During the second quarter of 2005, the Company changed its standard costing for VITOSS inventory. However, the Company did not maintain
effective control over the processes associated with allocation of overhead costs included in inventory. Specifically, the methodology originally used to allocate overhead costs to VITOSS inventory was incorrect and resulted in an overstatement of
VITOSS inventory at June 30, 2005 and an understatement of research and development expenses for the three and six months ended June 30, 2005. Additionally, the process lacked the

| | appropriate internal reviews. The error was corrected by recording adjustments to the Companys consolidated financial statements for the second quarter
prior to the public release of the consolidated financial statements.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We implemented the following measures during the quarters ended
September 30, 2005 and December 31, 2005 to remediate this matter and we tested the effectiveness of these internal controls and determined that these controls were operating effectively as of December 31, 2005:



| |  |  | We conduct more frequent reviews over inventory valuation, including the overhead allocation,
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | We realigned job responsibilities and staffing to more effectively manage the process described above.
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | We completed the implementation of an automated manufacturing system to track the allocation of overhead to products and have tested its effectiveness relative to internal control.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There was no other change in our internal control over financial reporting during the quarter ended December 31, 2005, that has
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 (Item 9A(b)), that Orthovita, Inc. (the Company) did not maintain effective internal control over financial
reporting as of December 31, 2005, because of the effect of the material weakness identified in managements assessment regarding its accounting for inventory, 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.

A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material
misstatement of the annual or interim financial statements will not be prevented or detected. The following material weakness has been identified and included in managements assessment as of December 31, 2005: the Company did not maintain
effective controls over the processes associated with its year-end physical inventory count. Specifically, the Companys policies and procedures over its year-end physical inventory count process did not provide for an appropriate level of
training to adequately prepare personnel involved in the physical inventory count, and did not provide for sufficient supervision and review by appropriate company personnel of the physical inventory count results and certain reconciliations
prepared in connection with the physical inventory count. As a result of these internal control deficiencies, the Company completed an inaccurate physical count of inventory on hand at December 31, 2005 and performed an inaccurate compilation
of inventory count tags. These deficiencies resulted in a misstatement of inventory as of December 31, 2005. Additionally, these deficiencies could result in a material misstatement of inventory in the Companys annual or interim
consolidated financial statements. Accordingly, management determined that these control deficiencies constitute a material weakness as of December 31, 2005.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Orthovita, Inc. and subsidiaries as of December 31, 2005 and 2004, and the
related statements of operations, shareholders equity and comprehensive income (loss), and cash flows for each of the years in the three-year period ended December 31, 2005. The aforementioned material weakness was considered in
determining the nature, timing, and extent of audit tests applied in our audit of the 2005 consolidated financial statements, and this report does not affect our report dated March 16, 2006, which expressed an unqualified opinion on those
consolidated financial statements.

In our opinion, managements assessment that the Company did not maintain effective internal control over
financial reporting as of December 31, 2005, 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, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting
as of December 31, 2005, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

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, 2005 and 2004, and the related consolidated statements of operations, shareholders equity and comprehensive income (loss), and cash flows for each of the years in the
three-year period ended December 31, 2005. 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, 2005 and 2004, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2005, in conformity with U.S.
generally accepted accounting principles.

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, 2005, 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, 2006 expressed an unqualified opinion on managements assessment of, and an adverse opinion on 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 biomaterials company with proprietary technologies for the development and commercialization of synthetic, biologically active, tissue engineering products for orthopedic and neurosurgical applications. Our products are
used in the regeneration of bone. Our near-term commercial business is based on our internally developed VITOSS® Bone Graft Substitute technology platform, which is designed to address the non-structural bone graft market by offering synthetic alternatives to the use of autograft or cadaver-derived
bone material to meet a broad range of orthopedic clinical needs in the spine, trauma, joint reconstruction, revision surgery and extremities markets, 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® Synthetic Cortical Bone technology platform, which is designed for injections into osteoporotic spines to treat vertebral compression fractures (VCFs). We have agreements
with Kensey Nash Corporation (Kensey) and Angiotech Pharmaceuticals, Inc. (Angiotech) (a shareholder of the company), that allow us to develop and market other synthetic-based biomaterial products, and continue to pursue
similar relationships with other companies in biomaterials.

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 and IMBIBE®Bone Marrow
Aspirate Device. Outside of the U.S., we primarily utilize a network of independent, stocking distributors to market VITOSS, CORTOSS, and ALIQUOT®Micro 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 financial statements, and the reported amounts of revenues and expenses during the reporting period. 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., our European branch operations, 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 potentially dilutive securities and is computed by
dividing net loss applicable to common shareholders by the weighted average number of shares of Common Stock outstanding for the period. Diluted net loss per common share data is computed assuming the conversion or exercise of all dilutive
securities such as Preferred Stock and Common Stock options and warrants. As of December 31, 2004 and 2003, 117 and 307 shares, respectively, of outstanding Preferred Stock were assumed converted into 685,816 and 1,799,531 shares of Common
Stock, respectively for the basic and

diluted net loss per common share calculation as these shares automatically converted to Common Stock when the beneficial ownership limitation lapsed (see
Note 10). As of December 31, 2005, no Preferred Stock was outstanding. However, Common Stock options and warrants of 8,671,183, 7,819,977 and 6,060,843 were excluded from our computation of diluted net loss per common share for the years ended
December 31, 2005, 2004 and 2003 since they were anti-dilutive due to our losses.

Revenue Recognition

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. We do not allow product returns or exchanges. We have no
post-shipment obligations to our customers. 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 sales discounts are not offered. 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.

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 Trust. The net proceeds from the financing were first allocated to the fair value
of the Common Stock on the date of the transaction (which was $4,777,893), and the $5,222,107 remainder of the net proceeds was allocated to the revenue interest obligation in accordance with Emerging Issues Task Force Issues No. 88-18,
Sales of Future Revenues (EITF 88-18). On March 22, 2002, we amended the original financing, which resulted in a one-time increase to the revenue interest obligation of $1,945,593, increasing the balance of
the revenue interest obligation to $7,167,700 as of December 31, 2005 and 2004.

##### Table of Contents

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, 2005 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 6). Revenue interest expense of $989,287, $837,844 and $642,850 has been
recorded for the years ended December 31, 2005, 2004 and 2003, respectively. The revenue interest under this agreement is treated as interest expense in accordance with EITF 88-18, Sales of Future Revenues.

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 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. A valuation allowance has been established against all of our deferred
tax assets since, given our history of operating losses, the realization of the deferred tax asset is not assured.

Accounting for Stock Options Issued to Employees and Non-employees

For periods through December 31, 2005, 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 is 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. SFAS No. 123, Accounting for Stock-Based Compensation, (SFAS No. 123) established accounting and disclosure requirements using a fair-value based method of
accounting for stock-based employee compensation plans. Under SFAS No. 123, compensation cost for the fair-value related to stock options is computed based on the value of the stock options at the date of grant using an option valuation
methodology, typically the Black-Scholes model. As required by SFAS No. 123, as amended by SFAS No. 148, Accounting for Stock-Based Compensation, we apply the SFAS No. 123 fair-value method of accounting to non-employee
stock option grants. For the years ended December 31, 2005, 2004 and 2003, we recorded $146,313, $439,068, and $689,762, respectively, of expense related to SFAS No. 123 for our non-employee stock option grants. For options granted to
employees, SFAS No. 123 allows a company either to record the Black-Scholes model value of the stock options in its statement of operations or continue to record the APB No. 25 intrinsic value in its statement of operations and disclose
the SFAS No. 123 fair value. For options granted to employees, we apply the intrinsic value based method of accounting under APB No. 25, and disclose the SFAS No. 123 fair value.

In December 2004, the FASB issued SFAS No. 123R, Share-Based Payment. This statement revises SFAS No. 123, and requires companies to expense the
value of employee stock options and similar awards. The effective date of this standard is the first annual period beginning after June 15, 2005, which is January 1, 2006 for the Company.

##### Table of Contents

Under SFAS No. 123R, we will be required to expense stock options in our Consolidated Statements of Operations when they are granted. The actual effect
on net loss and loss per share will vary depending upon the number of grants of options in 2006 and future periods as compared to prior years. We have selected the Black-Scholes option-pricing model, on a modified prospective transition method, as
the most appropriate fair-value method for our awards and will recognize compensation costs over the vesting periods of the awards. We expect to record approximately $1,700,000 during the year ended December 31, 2006 related to SFAS
No. 123R .

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, options to purchase approximately 1,110,000 shares of our Common Stock were subject to
this acceleration. 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 below for the
year ended December 31, 2005, includes the estimated future compensation expense that would have otherwise been recognized in our consolidated statement of operations with respect to these options under SFAS No. 123R. Had these options not been
accelerated, the expense related to the 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 following table illustrates the effect on net loss if the fair value method had been applied to all outstanding and unvested stock option grants in each period.

Pro forma financial information required by SFAS No. 123 has been determined as if we had accounted for all
outstanding and unvested stock option grants using the Black-Scholes fair value option pricing model with the following weighted average assumptions for the years ended December 31, 2005, 2004 and 2003:



|                                               |  |      |         |   |      |   |         |      |  |   |         |

The resulting pro forma compensation charge presented 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. The resulting translation adjustments are accumulated as a separate component of shareholders equity (accumulated
other comprehensive income). Revenues and expenses are translated at average exchange rates in effect during the period with foreign currency transaction gains and losses, if any, included in results of operations.

Supplemental Cash Flow Information

During
2005, 2004 and 2003, respectively, we issued options and/or warrants for the purchase of 48,398, 129,250 and 354,100 shares of Common Stock with various exercise prices to certain vendors in consideration for services valued at $146,313, $439,068
and $1,007,262, respectively.

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

In addition, during 2003, we issued an aggregate 84,281 shares of our Common Stock valued at $268,521 as payment of dividends to our Series A 6%
Adjustable Cumulative Convertible Voting Preferred Stock (Series A Preferred Stock) shareholders (see Note 10).

In 2005, 2004 and 2003, we
issued 9,667, 10,434 and 25,000 shares of Common Stock, respectively, valued at $38,093, $47,798 and $93,000, respectively, pursuant to a clinical assessment agreement. In addition, during the year ended December 31, 2005, a restricted stock
award of 20,928 shares was made to our non-employee directors in consideration of their services. The award was valued at $89,991 and is subject to certain vesting provisions.

In 2005, we incurred capital lease obligations of $107,982.

In 2005, 2004 and 2003, cash paid for interest expense and
revenue interest expense was $1,074,197, $933,592 and $732,535, respectively. The Company paid no income taxes in 2005, 2004 and 2003.

Recent Accounting Pronouncements

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. We do not expect the adoption of SFAS No. 151 to have a material impact on our financial statements.

Reclassifications

Certain amounts from prior years have been reclassified to conform to the 2005 presentation.

3. 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, 2005 and 2004, cash, cash equivalents and investments consisted of the following:

The increase in inventories from 2004 to 2005 has primarily been a result of production of inventory to support
the multiple commercial launches of new product configurations under our VITOSS FOAM product platform, VITAGEL, and the production of CORTOSS to support product sales in Europe. For the year ended December 31, 2005 and December 31, 2004,
cost of sales includes a provision of $1,606,420 and $1,590,856, respectively, to write down inventory to its estimated net realizable value.

and $2,364,512 at December 31, 2005 and 2004, respectively (see Note 7). Depreciation expense for the years ended December 31, 2005, 2004 and 2003 was $1,279,335, $1,165,475, and $1,146,178, respectively.

6. 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 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 EITF 88-18. On March 22, 2002, we amended the original financing, which
resulted in a one-time increase to the revenue interest obligation of $1,945,593, increasing the balance of the revenue interest obligation to $7,167,700 as of December 31, 2005 and 2004.

The revenue interest 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 Bone Graft Substitute, CORTOSS and any structural bioactive device developed, 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 Bone Graft Substitute 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.

##### Table of Contents

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 January 2004, the revenue interest assignment agreement with Royalty Trust was amended by mutual agreement to reduce the advance payment for 2004 from $2,000,000 to $1,100,000. Of the
$1,100,000 paid to Royalty Trust, $837,844 was earned in 2004 and the balance of $262,154 was included in prepaid revenue interest expense on the accompanying consolidated balance sheet as of December 31, 2004, and was repaid to us during the
first quarter of 2005. In February 2005, the revenue interest assignment 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,
$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 is scheduled to be repaid to us in April of 2006. In December
2005, the revenue interest assignment 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. The amount of the
advance payment remains $3,000,000 in each of the years 2007 through 2016. While we believe that we will have sufficient cash at the end of 2006 to make the required $3,000,000 advance payments to Royalty Trust during 2007, we cannot be certain that
we will have sufficient cash to meet our advance payment obligations for the years 2008 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 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, 2005 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 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. Revenue interest expense of $989,287, $837,844 and $642,850 has been recorded for the years ended December 31, 2005, 2004 and 2003, respectively. The revenue interest under this agreement is treated as interest expense in
accordance with EITF 88-18.

Our obligation to pay the revenue interest is secured by our licenses, patents and trademarks relating to certain of our
products, including VITOSS Bone Graft Substitute, CORTOSS and any structural bioactive device developed, in North America and Europe, and the 12% revenue interest we pay to one of our wholly-owned subsidiaries, on the sales of these products
(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 times (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, 2005, we were in compliance with all financial covenants. 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;
|- |  | ------------------------------------------------------------------------------------------------------------------



F-13

##### Table of Contents

| |  | 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 one of our wholly owned subsidiaries;
|- |  | -----------------------------------------------------------------------------------------------



| |  | 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 of the breach 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 and investment 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,
2005, we would have owed Royalty Trust $19,606,958. As of December 31, 2005, we do not expect to be out of compliance in the foreseeable future with the financial covenants of the revenue interest obligation.

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 second step of the calculation is reduced by the sum of $3,333,333 and the actual 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. In the event that we were required to repurchase 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 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.

##### Table of Contents

In March 2003, 85 shares of Series A Preferred Stock were voluntarily converted into 498,241 shares of Common Stock in
accordance with the terms of the Series A Preferred Stock. On June 27, 2003, the shares of Series A Preferred Stock became subject to an automatic conversion provision set forth in the Statement of Designations, Rights and Preferences of the
Series A Preferred Stock (the Series A Preferred Stock Designations) as a result of the average of the closing prices of our Common Stock as reported on the Nasdaq National Market over the 20 trading days ended June 26, 2003. During
2005 and 2004, 117 shares and 190 shares of Series A Preferred Stock, respectively, automatically converted into 685,816 and 1,113,714 shares of Common Stock, respectively, which have been included in the computation of basic and diluted loss per
share for years ended December 31, 2004 and 2003.

On July 9, 2003, following the automatic conversion of the Series A Preferred Stock into
shares of Common Stock, we called for redemption on July 25, 2003 all of the warrants to purchase an aggregate 9,466,588 shares of our Common Stock that were issued during July and October 2002 as part of our Series A Preferred Stock financing
and offered all holders of the warrants the option to pay the exercise price by the surrender and cancellation of a portion of shares of Common Stock then held by the holder of such warrants or issuable upon such exercise of the warrants. Any shares
so surrendered by holders electing the cashless exercise alternative offered by us were to be valued at $3.59 per share of Common Stock and credited toward the total exercise price due us upon the exercise of the warrants. This amount
was equal to the average of the closing sale prices of our Common Stock as reported on the Nasdaq National Market for the 20 trading days preceding July 8, 2003, the date on which our Board of Directors approved the redemption of the warrants.
Holders of the warrants called for redemption elected to exercise all of their warrants pursuant to the cashless exercise alternative offered by us and described above. Accordingly, during July 2003, we issued an aggregate 5,186,681 shares of our
Common Stock upon the cashless exercise of the warrants to purchase an aggregate 9,466,588 shares of our Common Stock. In accordance with the Series A Preferred Stock Designations, all of the redemption features of the Series A Preferred Stock were
within our control; therefore, the Series A Preferred Stock is classified within shareholders equity on our consolidated balance sheets.

Dividends on Series A Preferred Stock

Dividends on the Series A Preferred Stock accrued and were cumulative from the date
of issuance of the Series A Preferred Stock, and were paid in-kind through March 31, 2003. The dividend rate (the Dividend Rate) on each share of Series A Preferred Stock was 6% per year on the $10,000 stated value of the
Series A Preferred Stock. During the year ended December 31, 2003, we declared and paid dividends of $268,521 on the Series A Preferred Stock. These dividends were paid in-kind by issuing an aggregate of 84,281 shares of our Common Stock. Due
to the automatic conversion during the second quarter of 2003 of the Series A Preferred Stock described above, no dividends were required to be paid for periods after March 31, 2003.

The original terms of the Series A Preferred Stock stated that beginning after June 30, 2004, for any shares of Series A Preferred Stock still outstanding and not
converted to Common Stock, the dividend rate will increase each quarter by an additional two percentage points per year, up to a maximum dividend rate of 14% per year. Accordingly, for the year ended December 31, 2003, we recorded $850,869
of dividend accretion related to the higher dividend rates applicable to the Series A Preferred Stock for periods beginning after June 30, 2004 in accordance with Staff Accounting Bulletin No. 68, Increasing Rate Preferred
Stock (SAB 68).

Common Stock

During the year ended December 31, 2005, we issued 9,667 shares of Common Stock, valued at $38,093 pursuant to a clinical assessment agreement, which was included in research and development expenses on the

consolidated statements of operations. Additionally, during the year ended December 31, 2005, a restricted stock award of 20,928 shares was made to our
non-employee directors in consideration of their services. The award was valued at $89,991 and is subject to certain vesting provisions.

In December 2005,
we sold 4,318,182 shares of Common Stock to institutional investors at a price of $3.00 per share for net proceeds of $12,929,546.

In July 2004, we sold
5,681,818 shares of our Common Stock to Angiotech for net proceeds of $24,024,375. Additionally, in 2004, we issued 10,434 shares of Common Stock valued at $47,798 pursuant to a clinical assessment agreement, which was included in selling and
marketing expenses on the consolidated statements of operations.

During June and July 2003, we sold 4,892,856 shares of Common Stock for net proceeds of
$12,392,785. The investors also received five-year warrants to purchase 978,573 shares of Common Stock, exercisable for cash only, at an exercise price of $4.00 per share, subject to certain weighted average anti-dilution adjustments. Additionally,
we issued to the placement agent for the transaction five-year warrants to purchase an aggregate 146,786 shares of our Common Stock at an exercise price of $4.00 per share which were valued at $278,000. We incurred additional costs of $10,767 during
2004 associated with the sale of the Common Stock and warrants, which were offset against the proceeds of the transaction. Additionally in 2003, we issued 25,000 shares of Common Stock valued at $93,000 pursuant to a clinical assessment agreement,
which was included in selling and marketing expenses on the consolidated statements of operations.

Equity Compensation
Plan

We have an Equity Compensation Plan (the Plan) that provides for incentive and nonqualified stock options, restricted stock awards and
other equity incentives to be granted to key employees, consultants and advisors. The Plan is the only plan under which stock options have been granted, and has been approved by our Shareholders.

Stock Options

Options are granted with
exercise prices equal to or greater than the fair market value of the Common Stock on the date of grant. Generally, incentive stock options become exercisable in equal installments over a four-year period and nonqualified stock options to
non-employee consultants are issued fully vested. The options remain exercisable for a maximum period of ten years.

As of December 31, 2005, there
were 10,000,000 options authorized for issuance under the Plan, 1,521,648 options available for grant under the Plan and 6,101,126 exercisable options outstanding with a weighted average exercise price of $3.95 per share.

For all outstanding options, the weighted average exercise price per share is $3.84 with a weighted average remaining contractual life of approximately seven years.

12. 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:



|                    |  |                        |            |   |      |   |            |      |  |   |            |

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 includes net operating loss carryforwards 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. These tax assets are amortized over periods generally ranging from 10 to 17
years for tax purposes.

As of December 31, 2005, we had approximately $62,310,000 of federal net operating loss carryforwards, $67,200,000 of state
net operating loss carryforwards and $9,310,000 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 income tax regulations, since a change in ownership as defined in
Section 382 of the Internal Revenue Code 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. Federal and
Pennsylvania research and development tax credits of $1,138,172 and $102,461 begin to expire in 2010 and 2014, respectively.

Revenue Interest Obligation (see Note 6)

Agreement with Kensey Nash Corporation

In
March 2003, we entered into a development, manufacturing and supply agreement with Kensey to jointly develop and commercialize new 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 jointly developed approved or cleared product for seven
years from first commercial sale of the co-developed product and we will market and sell the product worldwide. In February 2005, the first agreement, under which the VITOSS FOAM products have been commercialized, was extended until 2014. 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 products. 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. In February 2005, we expanded our existing relationship with Kensey and agreed to pursue co-development of soft tissue repair products for orthopedics. Similar to the terms of the original agreement signed in March 2003, Kensey
will manufacture the new co-developed soft tissue products and we will market and sell the products worldwide, with Kensey receiving a royalty on the net sales.

During the years ended December 31, 2005 and 2004, we purchased $4,808,552 and $6,614,458, respectively, of product inventory manufactured by Kensey on our behalf. As of December 31, 2005 and 2004, we owed Kensey $1,323,595 and
$1,511,862, 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 the consolidated statements of operations as we recognize product sales revenue from our customers.

Since the initial launch of VITOSS Bone Graft
Substitute in 2000, we have been obligated to pay to one of the products co-inventors a royalty up to an aggregate payment of $5,000,000 on VITOSS Bone Graft Substitute product sales. In July 2004, Kensey purchased this royalty right from the
co-inventor effective as of April 1, 2004. We are now paying these royalties to Kensey.

Agreement with Cohesion Technologies, Inc., an affiliate of
Angiotech Pharmaceuticals, Inc. (a shareholder of the Company)

In June 2004, we entered into an agreement with Cohesion Technologies, Inc. a wholly-owned
subsidiary of Angiotech, to distribute, market and sell CoStasis (which we re-branded as VITAGEL Surgical Hemostat), a composite liquid hemostat, and the CELLPAKER plasma collection system, used together with VITAGEL, to surgical customers
throughout North America, with an option to expand the VITAGEL territory to include the European Union (EU) and the rest of the world. Under the agreement, we have obligations to purchase the products and make royalty payments to
Angiotech based on the net sales of such products. Effective September 30, 2005, we entered into an amendment to the agreement necessary to transition the manufacture of the products and accessories from Angiotech to us. In addition, the
amendment changes the royalty rate payable by us to Angiotech and modifies the method for calculating net sales of such products. Angiotech decided to cease to manufacture VITAGEL by November 2005; therefore, in October 2005, we purchased all
available existing products, accessories and work-in-process from Angiotech for $1,800,000, which is expected to be sufficient to meet our operating requirements through mid 2006. Additionally, on November 30, 2005, we submitted a

Duplicate PMA for VITAGEL to the FDA through a Grant of License from Angiotech to reference their PMA. FDA approval of the PMA submitted by us, if obtained,
will allow us to sell VITAGEL product that is manufactured on-site in our Malvern, Pennsylvania facility. As of December 31, 2005, we had included in inventory VITAGEL valued at $653,835 that was manufactured on-site at our Malvern Facility. We have
no assurance that we will obtain FDA approval to sell VITAGEL manufactured by us prior to our current supply of VITAGEL being exhausted. We may not have sufficient inventory of VITAGEL during the second half of 2006 to support customer demand.

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.
