Business Overview We are a medical device company with a complementary combination of spinal implant and orthobiologic technologies, an expanding product portfolio and distribution channels specifically addressing the spinal surgery market. Our product portfolio addresses what we believe are two of the fastest growing areas in the medical device industry--spinal implants and orthobiologics. Virtually all spine fusion procedures require the use of a bone graft and a majority of these procedures also use spinal implants. We offer three distinct product lines which can be used in combination for spinal fusions: spinal implants, synthetic bone graft materials and products used to derive growth factors. Because spine surgeons are the primary customers for each of our product lines, we believe our complementary product portfolio provides substantial cross selling opportunities to our distribution network. We plan to develop and commercialize new products which will allow us to offer our customers a more comprehensive solution for spine fusion procedures. In the spinal implant product category, we offer the Synergy Spinal System and the C-Tek Anterior Cervical Plate system. Our current product offering is applicable to thoraco-lumbar and cervical spine fusions, which we believe represent approximately 75% of spine fusion procedures. We believe our spinal products in development, which include intervertebral cages, will provide us with the products necessary to address the remaining spine fusion procedures that utilize spinal implants. Our principal orthobiologic offering includes synthetic bone graft products and AGF (Autologous Growth Factors) related products. Our Pro Osteon products are implanted in a bone deficit and provide a matrix that facilitates new bone ingrowth. Pro Osteon was the first synthetic bone graft substitute to obtain FDA approval for orthopedic applications. Our BonePlast is a resorbable bone void filler that is replaced by the patient's own bone during the healing process. In the second quarter of 1999, we commercially launched our AGF related products. AGF is a concentrate of growth factors derived intraoperatively from platelets in a patient's own blood. These growth factors are involved in initiating the bone healing cascade. We believe AGF will have application in a wide variety of bone and soft tissue procedures. Spine Anatomy The spinal column consists of 24 separate bones called vertebrae that are connected together to permit a normal range of motion. The spinal cord, the body's central nerve column, is enclosed within the spinal column. Vertebrae are paired into what are called motion segments that move by means of three joints: two facet joints and one spinal disc. The typical spine, as it relates to spinal implants, is made up of the following four main regions: . Cervical vertebrae are the first seven vertebrae in the neck; . Thoracic vertebrae are the next twelve vertebrae in the chest or rib cage; . Lumbar vertebrae are the next five vertebrae in the lower back; and . The sacrum. Together, the thoracic vertebrae and the lumbar vertebrae are frequently referred to as the thoraco-lumbar region of the spine. Spine Disorders The following are the four major categories of spine disorders: . Degenerative conditions. Degenerative conditions in the facet joints and disc can result in instability and impingement on the nerve roots as they exit the spinal canal, causing back pain or radiating pain in the arms or legs. . Deformities. Deformities, such as scoliosis, are deviations in the normal curvature and alignment of the spine. Deformities range in severity from cosmetic issues through varying levels of pain, discomfort or reduced function. . Trauma. Trauma, or injuries to the spine, if not corrected, can result in instability, pain, damage to the spinal cord and/or nerve roots, paralysis and deformity. . Tumors. Tumors in the spine typically occur in the vertebral body and eventually result in fracture of the vertebral body, causing instability, pain and deformity. Spinal Implant Market Overview The prescribed treatment for spine disorders depends on the severity and duration of the disorder and the success or failure of non-operative therapies. Non-operative therapies include bed rest, medication, lifestyle modification, exercise, physical therapy, chiropractic care and steroid injections. However, non-operative treatment options are not effective in many cases, and we estimate that over 500,000 patients undergo spinal surgery, such as spine fusions and spinal discectomies, each year in the United States. The number of spine fusion procedures performed annually in the United States is estimated to exceed 300,000. Advanced cases of spine disorders can require that surgeons remove all or part of a damaged disc and/or fuse two or more adjoining vertebrae together. A fusion involves the placement of bone graft material between two vertebrae and may involve the use of spinal implants to immobilize the vertebrae while they fuse together. The bone graft is intended to provide a matrix that facilitates new bone ingrowth. Complete formation of new bone may take six to eighteen months. For many years, surgeons have sought a means to increase the rate of new bone formation at a surgical site. However, until recently, no growth inducing agents were commercially available. We estimate that approximately 50% of all spine fusion procedures are performed in the thoraco-lumbar spine generally using posterior instrumentation systems (i.e. hooks, rods and screws), approximately 25% are performed in the cervical spine generally using cervical plates, and approximately 25% are performed throughout the spine using intervertebral devices, also called spine cages. Our current spinal implants address the instrumented procedures in the thoraco-lumbar spine and plated cervical spine fusions. Our Spinal Implant Products Synergy Spinal System. Our Synergy Spinal System consists of rods, hooks and screws that are attached to vertebrae adjacent to an injured or defective area of the spine. Our system is a "universal" implant system that allows surgeons to treat both the thoracic and lumbar portions of the spine. We believe our Synergy Spinal System offers a number of benefits, including the following: . Ease of Use. Our Synergy Spinal System was engineered to be easy for surgeons to use, reducing surgical time and requiring less manipulation. The screws and hooks are top tightening, the rods do not require pre-loading of additional components, and all implants allow for free rod rotation. . Our patented variable locking screw design allows the surgeon to angle and tighten screws in many planes, reducing the amount of required rod bending and facilitating rod placement. . The patented design of the external hexagonal head of our double hex set screw shears off at a predetermined torque, allowing the surgeon to consistently tighten screws to the right tension. However, an internal hexagonal cavity remains to allow the surgeon to remove the set screw if necessary. . Universal Application. Synergy implants come in various sizes and types to meet the surgeon's preferences and the patient's anatomy, providing a secure anatomic fit for virtually any pathology. The Synergy Spinal System does not require that the surgeon follow a single surgical protocol, but provides several options, and can be used in both anterior and posterior applications, in both adults and children. . Smaller and Stronger. We offer Synergy implants in either stainless steel or titanium. The strength of the Synergy implants provides resistance to fatigue and allows the implants to be smaller than many competing products. Titanium implants are preferred in many foreign markets and are being used increasingly in the United States because titanium allows magnetic resonance imaging of the spinal area. . Low Profile. Profile describes the prominence of implants above the normal bony surfaces of the spine. The Synergy Spinal System was designed to minimize the height and bulk of its implants, reducing the risk of irritation, inflammation and infection for the patient. It has been ranked as having one of the lowest profiles of commonly available spinal implant systems. C-Tek Anterior Cervical Plate System. Our C-Tek is a titanium plate that is attached using screws to two or more vertebrae in the cervical spine to facilitate spine fusion. We received FDA 510(k) clearance of the C-Tek in late 2000, and introduced it to the market in the first quarter of 2001. We believe our C-Tek System offers a number of benefits, including the following: . Low Profile and Narrow Width. The C-Tek has one of the lowest profiles among the cervical plates available to the market, and its width is narrow. These characteristics are particularly important in the cervical spine, where anterior implants must be placed close to soft tissues in the throat. . Fixed and Slotted Hole Versions. While most competitors' cervical plate systems incorporate either a fixed hole or a slotted hole design, our C-Tek is available in either design in order to accommodate the physician's surgical philosophy. These features allow the surgeon to create rigid, semi- rigid or load-sharing constructs. . One-Step Locking. All cervical plate systems must incorporate some safeguard to prevent the backing out of screws, which can be a significant problem because the implants are placed very close to soft tissues in the throat. While most other cervical plate systems require a locking procedure to be applied to each screw, our C-Tek incorporates a proprietary one-step locking mechanism that enables all screws to be locked with a single procedural step. TPS Telescopic Plate Spacer. Our TPS is an expandable titanium spacer intended to replace one or two vertebral bodies that must be removed due to cancer. This device combines the functions of an anterior plate and a vertebral column spacer and it incorporates a patented telescoping feature. We received a Humanitarian Device Exemption (HDE) from the FDA in early 2000 for the cervical spine version of the TPS. We plan to seek FDA clearance of a version for thoraco-lumbar applications in 2001. Orthobiologics Market Overview Bone is a composite material made up of bone cells and a porous matrix. The matrix is composed of collagen and ceramic calcium phosphate crystals. Bone continuously remodels itself, thereby repairing the small imperfections formed due to everyday activity. Bone will often spontaneously repair minor fractures without surgical intervention. However, major skeletal deficiencies from trauma, spinal instability, degenerative conditions and tumor will frequently require a surgical procedure involving bone graft. There are three types of orthobiologic bone grafting products: . Osteoconductive materials, which act as a scaffold for bone and tissue growth while healing occurs; . Osteoinductive materials, which promote or stimulate bone or tissue growth; and . Combination materials with both osteoconductive and osteoinductive characteristics. Bone Grafts. It is estimated that bone grafts are used in over 600,000 procedures annually in the United States. They are used for a wide variety of indications including spine fusions, total joint surgery, maxillofacial applications and other surgical procedures. There are currently three major categories of bone grafts: autograft, allograft and synthetic bone graft substitutes. We estimate that synthetic bone graft substitutes are used in about 11% of the bone graft procedures performed annually in the United States, with the remaining procedures divided approximately equally between autografts and allografts. Autograft bone is bone harvested from another part of the patient's skeleton, typically the iliac crest or hip. Once harvested, the bone is grafted to the site of the bone deficit. Harvesting bone typically requires a second surgical procedure, increases total operating time and expense, and can lead to complications such as infection, chronic pain, deformity and excess blood loss. Autograft bone can have both osteoinductive and osteoconductive properties. Allograft bone is bone obtained from a cadaver. There are numerous bone banks that obtain cadaver tissue from regional donor centers. Once obtained, the tissue is processed and configured into a variety of forms, including chips, paste, blocks, gels and putties. Strict donor screening standards and testing for infectious agents such as hepatitis B and HIV have significantly reduced the possibility of implant rejection and disease transmission. Allograft bone can have osteoconductive and osteoinductive properties, but we believe the growth factors contained in allograft bone may be compromised in some of the commonly used sterilization procedures. Synthetic bone graft substitutes are artificially produced and can be used in place of autograft or allograft or mixed with autograft or allograft. Synthetic bone graft substitutes are available in a wide range of forms, including granules, blocks, strips, gels, slurries and injectable bone graft cements. Synthetic bone graft substitutes generally have osteoconductive properties. Growth Factors. Specific naturally-occurring proteins, called growth factors, regulate bone generation by stimulating either the formation of new bone cells or the replication of existing cells. We believe that the combination of growth factors with bone grafts will be the next major advancement in bone grafting. To derive growth factors, a number of methods are under development, including recombinant DNA technology, gene therapy, extraction from cow bone and advanced filtration technologies. With recombinant DNA technology, the desired human growth protein gene is introduced into a production host, usually an animal, bacterial or yeast cell, and the host makes the human protein along with its own. These proteins are then concentrated and made into a usable form. Using filtration methods, the human growth factor proteins are removed from the patient's own blood. These proteins can be concentrated and combined with any of the three major categories of bone graft. Our Orthobiologic Products Bone Graft Substitutes. Our Pro Osteon bone graft substitute products are derived from the exoskeleton of two specific genera of coral and chemically converted into a material with porosity, architecture and chemical composition similar to that of human bone, using our proprietary manufacturing process. Due to its structure, the graft provides a matrix that facilitates new bone ingrowth. Our BonePlast bone void filler is a calcium sulfate (plaster-of- paris) material that resorbs and is replaced with bone during the healing process. Our line of osteoconductive bone graft products includes: Product Description Indication U.S. Regulatory Status - ------------------------- ---------------------------- ---------------------------- ---------------------------- Pro Osteon 500 Bone graft substitute.

Our Pro Osteon and BonePlast products compare favorably with autograft, allograft and other synthetic bone grafts used today. We believe our products: . Eliminate morbidity and cost associated with autograft harvesting; . Eliminate disease transmission and host rejection risk; . Require no special handling or storage conditions; . Can be prepared simultaneously with surgery; . Contain no fillers such as glycerol, which has been shown to have toxic effects; and . Are easily shaped by surgeons to fill bone voids or defects. AGF (Autologous Growth Factors). AGF is a concentrate of growth factors derived from platelets in a patient's blood which is used to encourage more complete and rapid bone growth in bone defects. Our two key products used to collect AGF are the UltraConcentrator Permeability Hemodialyzer and the Automated Processor. Cleared for marketing by the FDA in the fourth quarter of 1998, these products are used to produce a concentrated growth factor "gel" from platelets in the patient's own blood. Our AGF related products were commercially launched in 1999. In the AGF collection process, blood from the patient is separated into different component layers using a device called a cell washer, which is routinely available in the operating room during spine fusion and revision total joint replacement procedures. One of the layers, known as the "buffy coat," contains platelet-rich plasma and white blood cells. The buffy coat is processed using our proprietary filtering technology which super-concentrates the platelets and fibrinogen, producing a "cocktail" of growth factors, including Platelet-Derived Growth Factor and Transforming Growth Factor Beta. With the addition of thrombin, the fibrinogen contained in AGF is converted into fibrin, giving AGF a gel-like consistency. AGF can be combined directly with a bone graft material, such as our Pro Osteon and BonePlast products, as well as autograft and allograft, and placed at the bone graft site. The red cells and plasma component layers from the cell washer are returned to the patient, resulting in minimal blood loss. We believe that AGF provides the surgeon with the growth factors desired for faster and more complete bone graft healing and that AGF may be preferred by surgeons due to factors which include the following: . Many surgeons prefer autologous solutions, such as AGF, that are derived from the patient's own tissues; . AGF's gel-like consistency discourages migration from the bone defect site to other areas in the body; . AGF is a "cocktail" of many cell-stimulating growth factors; . Using the patient's own growth factors eliminates dosage concerns; and . The cost of AGF is lower than that anticipated for recombinant products under development. Business Strategy Our goal is to establish a leadership position in the development of products for the surgical treatment of spine disorders. In order to achieve this goal, we plan to undertake the following strategies: Expand and Enhance our Spinal Implant Product Portfolio. Until the recent launch of the C-Tek Anterior Cervical Plate system, our spinal products primarily targeted the thoracic and lumbar regions of the spine. With the release of the C-Tek and the development of additional spinal implants, including spine cages, we are creating a more complete product portfolio. This will allow us to offer physicians a comprehensive surgical solution. We plan to invest significant resources in research and development in an effort to introduce technological advancements in the spinal market. We will also consider the acquisition of companies and products to complement our current product platform. Capitalize on "First to Market" with our AGF Technology. Our AGF related products received market clearance in December 1998 and were nationally launched in June 1999. We were the first company to market FDA-cleared devices that extract and concentrate autologous growth factors intraoperatively to levels shown in studies to stimulate bone growth. Other synthetically derived growth factors are being developed and are in late stages of clinical trials or the Premarket Approval process, but we believe none are yet approved for use in the United States. We plan to capitalize on our "first to market" position by developing improvements to the process and completing the numerous ongoing clinical studies to prove the effectiveness of AGF. Also, we believe that AGF holds great promise in areas outside of orthopedics for wound-healing applications, such as general, cosmetic and maxillofacial surgery as well as burns. We are exploring partnering with companies that participate in the large and diverse wound-healing market in order to expand the use of AGF into these applications. Continue to Expand and Strengthen our Distribution Network. In the United States, we utilize independent agents as the primary channel to distribute our product portfolio. Many of the larger companies in our industry are transitioning from independent agents to a direct sales force. We have been the beneficiary of such transitions, as many highly qualified agents prefer to remain independent and find our product offering attractive. We intend to attract and retain independent agents who have many years of experience selling spinal products and strong relationships with spine surgeons and who can distribute all of our product lines. Our product offering presents cross- selling opportunities for our distribution network. We provide extensive technical training programs on new and current products and demonstrate how these products can be used in combination. We believe these efforts will enable us to further penetrate the spine market. Expand our Clinical Leadership Base. We intend to increase market awareness of our products through a combination of symposia, VIP tours and extensive training and education programs for leading spine surgeons and key opinion leaders. We also intend to enlist these leading physicians in various studies involving our products. Upon completion of these studies, we will seek to publish the results in well-known industry journals. Research and Development. As of March 1, 2001, our research and development department consisted of 24 full-time employees. We also engage outside consultants and academic research facilities for assistance with our new product development and will license technology from third parties under appropriate circumstances. We plan to continue to use outside resources for product research. In 1992, we formed the Synergy System Advisors, a group of prominent spine surgeons, that assisted in the development of the Synergy Spinal System. We have agreements with the advisors under which we pay royalties ranging from 5% to 7% of net revenues generated from the sale of certain products within the Synergy Spinal System. Our expenditures for research and development were $3.7 million in 1998, $4.2 million in 1999 and $5.3 million in 2000. Additional spinal implant and orthobiologic products which we currently have under development include: . Geo Structure. This unique titanium spacer has a geometric design which provides very high strength with a minimum amount of metal in the implant. This design will allow the surgeon to place a larger quantity of graft material at the graft site, which increases the probability of a successful fusion. It will also allow better radiographic visualization of the graft site postoperatively for better assessment of fusion. We submitted a 510(k) application for this product in the first quarter of 2001. . Intervertebral Cages. We are currently conducting mechanical testing on several alternative designs. Our objective is to develop a cage which would be a stand-alone device, expandable to optimize anatomic fit, and radiolucent. Intervertebral cages are currently Class III devices requiring Premarket approval from the FDA. . Artificial Disc. Our simple patented design, with no moving parts, could allow a surgeon to replace a diseased disc while maintaining motion of the spine in the affected segment, eliminating the need for fusion. We expect to begin animal studies on this device in mid-2001. . Use of BonePlast/Pro Osteon 200R for Vertebroplasty. Vertebroplasty is a treatment for compression fractures of the vertebrae, a common occurrence among osteoporotic patients. In this procedure, physicians generally insert bone cement into the vertebral body to restore the height of the vertebra and reduce pain. However, bone cement has certain undesirable characteristics and we believe that BonePlast combined with our Pro Osteon 200R may be uniquely suitable for this procedure. Animal trials are scheduled to commence in 2001. . Polymer-reinforced Pro Osteon Material. We have development efforts underway for a polymer-reinforced Pro Osteon material. We believe that increasing the strength of our resorbable version of Pro Osteon in various configurations, combined with AGF, holds promise for potential use as a natural, resorbable alternative to titanium and composite spinal implants currently available in the market. Such a product would be several years from the market, if developed at all. Animal trials are scheduled to commence in 2001. We currently have a number of prospective randomized clinical studies underway at a variety of institutions to demonstrate the efficacy of our AGF-related products for multiple indications. Intellectual Property As part of our ongoing research, development and manufacturing activities, we have a policy of seeking patent protection. Patents relating to particular products, uses or procedures, however, do not preclude other manufacturers from employing alternative processes or from successfully marketing substitute products. We believe that although patents often are necessary to protect our technology and products, the lengthy FDA approval process and certain manufacturing processes are more significant barriers to entry. Moreover, much of the proprietary technology and manufacturing processes developed by us reside in our key scientific and technical personnel and such technology and processes are not easily transferable to other scientific and technical personnel. The loss of the services of key scientific, technical and manufacturing personnel could have a material adverse effect on our business and results of operations. Spinal Implant Products. We own eight U.S. patents related to various aspects of our spinal implant products, including the bone anchor, the rod/anchor interface, instrumentation and transverse connectors. We have five U.S. patents pending concerning enhancements to our Synergy Spinal System and for several new products. Orthobiologic Products. We own eleven U.S. patents related to our orthobiologic products. Of these, two relate to our Pro Osteon 500R resorbable bone graft substitute, and three are for our AGF related products. We have four U.S. patents pending relating to several new products. In the fourth quarter of 1999, we purchased all of the intellectual property of Quantic Biomedical, Inc. Quantic previously had licensed to us the right to design, manufacture and market orthopedic products incorporating technology to produce AGF. We acquired this technology in order to preserve our access to all markets for our AGF related products. We require our employees, consultants and advisors to execute nondisclosure agreements in connection with their employment, consulting or advisory relationships with us. We also require our employees, consultants and some advisors to agree to disclose and assign to us all inventions conceived during the work day, using our property or which relate to our business. Despite any measures taken to protect our intellectual property, unauthorized parties may attempt to copy aspects of our products or to obtain and use information that we regard as proprietary. Finally, our competitors may independently develop similar technologies. Our trademarks include "Interpore(R)," "Cross Medical(R)," "Cross(R)," "Pro Osteon/(TM)/," "Pro Osteon 500/(TM)/," "Interpore 200(R)," "AGF/(TM)/," "Autologous Growth Factors/(TM)/," "UltraCon(TM)", "Synergy/(TM)/," "BonePlast/(TM)/," "TPS/(TM)/," "Geo/(TM)/ Structure," "C-Tek(TM)," "Integral(TM)" and "VLS(TM)." Customers, Sales and Marketing The decision to use our products is made by the orthopedic surgeon or the neurosurgeon. We direct our domestic marketing efforts to the approximately 14,000 practicing orthopedic surgeons in the United States in private practice, hospitals and orthopedic treatment centers. Of the approximately 14,000 practicing orthopedic surgeons, we estimate there are over 2,000 fellowship- trained spine surgeons. In addition to the orthopedic surgeons, we estimate that there are over 1,000 neurosurgeons performing spine fusion procedures that utilize implants. Our domestic sales organization consists of mostly independent agents with a few direct sales representatives. As of March 12, 2001, we had contracts with 38 independent agents which employed approximately 149 sales representatives and we employed two direct sales representatives. The domestic sales organization is managed by a Vice President of North American Sales and five division managers. We invoice hospitals directly, generally at list prices, and pay commissions to the agents and direct sales representatives. We provide consignment inventories to our independent agents, direct sales representatives and some hospitals. We select agent organizations and direct sales representatives for their expertise in spinal implant, orthopedic or medical device sales, their reputation within the surgeon community and their sales coverage within a geographic area. Each agent organization and direct sales representative is given an exclusive sales territory for some or all of our products and is subject to periodic performance reviews. In addition, each new independent sales agent and direct sales representative goes through training programs before initiating sales efforts for our products. We also require each independent agent and direct sales representative to attend periodic sales and product training. Outside of the United States, we distribute products only through independent distributors. We have a Vice President of International Sales, a Latin America sales manager and a European business liaison and have established distribution arrangements with 42 distributors in 38 countries. Our international sales represented approximately 23% of sales in 1998, 22% of sales in 1999 and 20% of sales in 2000. Sales to our international customers are denominated in U.S. dollars. In the United States, there are no significant customer concentrations, as we invoice hospitals directly for product used or shipped. However, in the international markets, we have a significant distributor in Spain that accounted for approximately 24% of our 2000 international sales and 5% of our 2000 worldwide sales. In order to improve shipping efficiencies and service to our international customers, in January 1998 we entered into an agreement with a contract warehouse in the Netherlands to ship bone graft products to customers in certain countries outside of North America. We participate in over two dozen professional meetings including the American Academy of Orthopaedic Surgeons Meeting, the North American Spine Society Meeting and the Congress of Neurological Surgeons. We also participate in scientific presentations and professional seminars at hospitals and provide funding for surgeon symposia from time to time. Third-Party Reimbursement We expect that sales volumes and prices of our products will continue to be dependent in large part on the availability of reimbursement from third-party payors. In the United States, our products are purchased by hospitals, who are reimbursed for the devices provided to their patients by third-party payors, such as governmental programs (e.g., Medicare and Medicaid), private insurance plans and managed care programs. These third-party payors may deny reimbursement if they determine that a device used in a procedure was not used in accordance with cost-effective treatment methods, as determined by the third- party payor, or was used for an unapproved indication. Also, third-party payors are increasingly challenging the prices charged for medical products and services. In international markets, reimbursement and healthcare payment systems vary significantly by country and many countries have instituted price ceilings on specific product lines. There can be no assurance that our products will be considered cost-effective by third-party payors, that reimbursement will be available or, if available, that the third-party payors' reimbursement policies will not adversely affect our ability to sell our products profitably. Particularly in the United States, third-party payors carefully review, and increasingly challenge, the prices charged for procedures and medical products. In addition, an increasing percentage of insured individuals are receiving their medical care through managed care programs, which monitor and often require pre- approval of the services that a member will receive. Many managed care programs are paying their providers on a capitated basis, which puts the providers at financial risk for the services provided to their patients by paying them a predetermined payment per member per month. The percentage of individuals covered by managed care programs is expected to grow in the United States over the next decade. We believe that the overall escalating cost of medical products and services has led to, and will continue to lead to, increased pressures on the healthcare industry to reduce the costs of products and services. There can be no assurance that third-party reimbursement and coverage will be available or adequate, or that future legislation, regulation, or reimbursement policies of third-party payors will not adversely affect the demand for our products in development or our ability to sell these products on a profitable basis. The unavailability or inadequacy of third-party payor coverage or reimbursement could have a material adverse effect on our business, operating results and financial condition. Manufacturing Spinal Implants. We contract with outside vendors for the manufacture of our spinal implant products, which are fabricated from medical grade stainless steel or titanium according to our specifications. Following the receipt of products at our facility, we conduct inspection, packaging and labeling operations. All of our current spinal implant products are distributed in a non-sterile condition, which is the industry standard for implant systems such as our Synergy and C-Tek. Certain future spinal implant products, such as the Geo Structure, may be provided in sterile packaging. Orthobiologics. Coral is the primary raw material used to manufacture our Pro Osteon products. The coral used in our products is sourced from two genera located in a wide variety of geographic locations. We presently harvest coral in tropical areas of the Pacific and Indian Oceans. We believe we have an adequate supply of coral for the foreseeable future. Coral is covered under an international treaty entitled Convention on International Trade of Endangered Species of Wild Fauna and Flora, which regulates the import/export of raw coral and products derived therefrom in approximately 140 nations around the world. To date, the limitations imposed by this treaty have not affected our ability to source raw coral. The manufacturing process for our Pro Osteon line of bone graft substitute products involves coral qualification and cutting, hydrothermal conversion, testing, packaging and sterilization of the product, all of which, with the exception of sterilization, are performed at our facilities. Some of the products and materials supplied by our vendors are currently sole- sourced, but we believe that we could locate alternative vendors for supply of these components. However, the UltraConcentrator, one of our products used to collect AGF, is manufactured under an exclusive supply agreement with a vendor that itself has a sole source of supply of the contained filter material. Although the filter material is not readily available through alternative sources, we believe there are suppliers that could supply alternate materials with equivalent function. In the event that a re-engineering of the product were necessary due to an interruption in supply from our current vendor, delays in product availability could occur and significant costs could be incurred, either of which could have a material adverse effect on our operations. Competition Spinal Implant Market. Many companies compete in the spinal implant market and competition is intense. We believe that our largest competitors in the United States offering spinal implants are Medtronic Sofamor Danek USA, DePuy AcroMed, Inc., a Johnson & Johnson company, and SYNTHES-STRATEC, Inc., each of which has substantially greater sales and financial resources than we do. Medtronic Sofamor Danek, in particular, has a broader spinal implant line. Other companies have developed and are marketing products based on technologies that are different from ours, including spine fusion cages, spinal implants designed to be used with minimally invasive or laparoscopic surgery, and allograft bone dowels. 10 Orthopedic Bone Graft Substitute Market. Our synthetic bone products compete principally with natural bone obtained from autograft procedures, considered the physician's "gold standard," with allograft bone obtained from cadavers and with other synthetic bone products. Autograft and allograft bone have been used as graft material for a much longer period than synthetic bone graft materials, and in order to maintain and increase future sales of our synthetic bone graft products, we will have to continue to demonstrate to the medical community the surgical and patient advantages, safety, efficacy, cost effectiveness and clinical results of our synthetic bone graft products. Competitive bone substitute products include: Grafton(R) demineralized bone products from Osteotech, DynaGraft demineralized bone products from GenSci Regeneration Technologies, OsteoSet(TM) calcium sulfate from Wright Medical Technology, Vitoss(TM) from Orthovita, as well as other bone substitute products used in non-orthopedic applications. Several other companies are pursuing additional synthetic bone graft materials for orthopedic applications which could ultimately compete with our synthetic bone graft products in the United States. Growth Factors. There is significant development activity ongoing that, if successful, would potentially produce products competitive with our AGF technology. Stryker Corporation has distribution rights to a recombinant human bone morphogenetic protein called OP-1. They have completed human clinical studies, but as of March 15, 2001 had not yet been able to obtain approval of their Premarket Approval application filed with the FDA. Genetics Institute, Inc. has a recombinant human bone morphogenetic protein (rhBMP-2) in human clinical studies, and we believe they plan to file a Premarket Approval application in 2001. Sulzer Orthopedics Biologics, a subsidiary of SulzerMedica of Switzerland, has an extract of bovine (cow)-derived bone growth protein that is in preclinical animal studies and may be in clinical evaluation. We compete in all of our markets primarily on the basis of product performance and price, as well as customer loyalty and service. Government Regulation Our products are regulated by the FDA under the federal Food, Drug and Cosmetic Act, as well as other federal, state and local governmental authorities and similar regulatory agencies in other countries. The FDA permits commercial distribution of a new medical device only after the FDA has cleared a 510(k) premarket notification or has approved a Premarket Approval application for such medical device. In general, the FDA will clear marketing of a medical device through the 510(k) premarket notification process if it is demonstrated that the new product is substantially equivalent, in terms of safety and intended use to certain 510(k) cleared products which are already commercially available and legally sold on the market. The Premarket Approval process is lengthier and more burdensome than the 510(k) premarket notification process. The Premarket Approval process generally requires detailed animal and clinical studies, as well as manufacturing data and other information. If clinical studies are required by the FDA, an Investigational Device Exemption is also required. An Investigational Device Exemption restricts the investigational use of the device to a limited number of investigational sites, investigators and patients. Its purpose is to prove safety and efficacy of the device. FDA approval of a Premarket Approval application indicates that the FDA concurs that a device has been scientifically proven, through the completion and submission of animal data, a completed Investigational Device Exemption and other pertinent information, to be safe and effective for its intended use. Our Synergy Spinal System received 510(k) marketing clearance from the FDA. We received 510(k) clearance from the FDA to market the anterior portion of the Synergy Spinal System in October 1994 and for the posterior portion of the system in July 1995. In September 1996, we developed a titanium version of the Synergy Spinal System for international distribution. We received FDA marketing clearance for the anterior portion of the titanium version in October 1995 and the posterior portion in January 1997. 11 In March 2000, the Food and Drug Administration approved a Humanitarian Device Exemption (HDE) for the cervical version of our corpectomy cage, the TPS Telescopic Plate Spacer. An HDE is designed to encourage the discovery and use of devices intended to benefit patients in the treatment or diagnosis of diseases or conditions that affect or are manifested in fewer than 4,000 individuals in the United States per year. In the case of the TPS, the approved indication is for the replacement of normal body structures following a vertebrectomy or corpectomy of the spine for metastatic disease in the cervical or cervical-thoracic spine. In October 2000, we received FDA 510(k) clearance to market our C-Tek Anterior Cervical Plate System. In October 1992, we received FDA approval to market Pro Osteon 500 for certain defects in the wide part of long bones. We subsequently received FDA approval to market it in granular forms and a wide variety of block configurations up to 30 cc's in total volume, and for additional indications including the treatment of cysts and tumors in long bones. Our Pro Osteon 200 and Interpore 200 were cleared for marketing for certain oral surgery, periodontal defects, craniofacial and orthognathic indications through 510(k) premarket notifications. In July 1997, the FDA cleared the use of a competitive synthetic bone graft substitute product with a 510(k). Prior to clearance of this device, companies were required to obtain marketing approval from the FDA for bone graft substitutes via the Premarket Approval process. It is possible that some clearances of other bone graft substitute products may now be obtained through the less burdensome 510(k) premarket notification process. This may increase competition. In September 1998, we received 510(k) clearance from the FDA for our Pro Osteon 500R resorbable bone graft substitute product. The approved indications include use in bony voids or gaps of the skeletal system, such as the extremities, spine and pelvis. In December 2000, we received 510(k) clearance from the FDA for our Pro Osteon 200R resorbable bone graft substitute product. In September, 1999, we received FDA 510(k) clearance for our BonePlast bone void filler for use in the extremities, spine and pelvis. In December 1998, we received FDA 510(k) clearances for the two key products in the AGF system, the UltraConcentrator Permeability Hemodialyzer and the Automated Processor. Other FDA requirements govern product labeling and prohibit a manufacturer from marketing an approved device for unapproved applications. If the FDA believes that a manufacturer is not in compliance with the law, it can institute proceedings to detain or seize products, issue a recall, enjoin future violations and assess civil and criminal penalties against the manufacturer, its officers and employees. We are registered as a medical device manufacturer with the FDA, with state agencies such as the Food and Drug Branch of the California Department of Health Services and with the European Community. These agencies inspect our facilities from time to time to determine whether we are in compliance with various regulations relating to medical device manufacturing, including the FDA's Quality System Regulations and ISO 9001/EN46001, which govern design, manufacturing, testing, quality control, sterilization and labeling of medical devices. We believe we are in compliance with the regulations established by these agencies applicable to our business. The European Community Notified Body, the FDA and the California Department of Health Services have inspected our manufacturing facilities and quality assurance procedures in the past and we expect them to continue to do so in the future. 12 With respect to our bone graft substitute products, we must also comply with the requirements of the Convention on International Trade of Endangered Species of Wild Fauna and Flora, or CITES. This is an international agreement signed by approximately 140 nations which regulates the import and export of products which are derived from endangered wildlife. Although the coral we use is not an endangered species, all harvested coral is subject to regulation under CITES. As a result, we must register and obtain licensure from the U.S. Department of Fish and Wildlife for both the import of raw coral and the export of finished product. We maintain several years' supply of coral to minimize the risk of supply interruptions. Because each shipment of product exported outside of the United States or its possessions requires individual permitting, and also to improve shipping efficiencies and service to our international customers, we entered into an agreement with a contract warehouse in the Netherlands for the purpose of international distribution of our products. We must also comply with registration requirements of foreign governments and with import and export regulations when distributing our products to foreign nations. Each foreign country's regulatory requirements for product approval and distribution are unique and may require the expenditure of substantial time, resources and effort to obtain and maintain approvals for marketing. In September 1995, we received approval to use the "CE" mark for our entire line of orthopedic and oral/maxillofacial synthetic bone graft materials. We received approval to use the "CE" mark for our spinal implant systems in 1998. The CE mark indicates that the products are approved for sale within 18 countries in the European Community and European Free Trade Association and that we are in compliance with the ISO 9001 and EN 46001 standards which govern medical device manufacturers that are marketing products in Europe. The CE mark is now also accepted by several countries outside of the European Community. Employees As of March 1, 2001, we had 117 full-time employees, of whom 35 were engaged in marketing and sales, 31 in manufacturing, 15 in regulatory affairs and quality assurance, 12 in general administration and finance and 24 in research and development. None of these employees is represented by a union, and we have never experienced a work stoppage. We consider our relations with our employees to be good. Certain Business Considerations Investors are cautioned that certain statements contained in or incorporated by reference into this Annual Report on Form 10-K, or which are otherwise made by us or on our behalf are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements that are predictive in nature, which depend upon or refer to future events or conditions, which include words such as "believes," "plans," "anticipates," "estimates," "expects" or similar expressions. In addition, any statements concerning future financial performance, ongoing business strategies or prospects, and possible future actions, which may be provided by our management, are also forward-looking statements. Forward-looking statements are based on current expectations and projections about future events and are subject to risks, uncertainties, and assumptions about our company, economic and market factors and the industry in which we do business, among other things. These statements are not guaranties of future performance and we undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. Actual events and results may differ materially from those expressed or forecasted in forward-looking statements due to a number of factors. Factors that could cause our actual performance and future events and actions to differ materially from such forward-looking statements, include, but are not limited to those discussed below and elsewhere in this Annual Report on Form 10-K. 13 We are dependent on a few products which may be rendered obsolete. We anticipate that most of our revenue growth in the future, if any, will come from our spinal implant products and from our orthobiologic products. There can be no assurance that we will be successful in increasing sales of our current product offering. Additionally, there can be no assurance that our efforts to develop new products will be successful. If our development efforts are successful, there can be no assurance that we will be successful in marketing and selling our new products. Moreover, our competitors may develop and successfully commercialize medical devices that directly or indirectly accomplish what our products are designed to accomplish in a superior and less expensive manner. If our competitors' products prove to be more successful than ours, our products could be rendered obsolete. As a result, we may not be able to produce sufficient sales to maintain profitability. If we fail to compete successfully against existing or potential competitors, our operating results may be adversely affected. Our principal global competitors with respect to our spinal implant product line are Medtronic Sofamor Danek USA, DePuy AcroMed, Inc., a Johnson & Johnson company, and SYNTHES-STRATEC, Inc. Our principal global competitors with respect to our orthobiologic products include Osteotech, Inc., GenSci Regeneration Technologies and Wright Medical Technology. Many of these companies have broader product lines than we do. Many potential customers have relationships with our competitors that could make it difficult for us to continue to penetrate the markets for our products. In addition, many of our competitors have significantly greater resources than we do. Accordingly, they could substantially increase the resources they devote to the development and marketing of products that are competitive with ours. We may not be able to develop new products that will be accepted by the market. Our future growth will be dependent on our ability to develop and introduce new products, including enhancements to our existing products. We cannot assure you that we will be able to successfully develop or market new products or that any of our future products will be accepted by our customers. If we do not develop new products in time to meet market demand or if there is insufficient demand for these products, our revenues and profitability may be adversely affected. The long-term efficacy and market acceptance of AGF is uncertain. Because our AGF related products were introduced only recently under a 510(k) clearance, we lack long-term clinical data regarding the efficacy and long-term results of AGF. To date, we have completed no long-term clinical studies of AGF. If long-term studies or clinical experience indicate that procedures involving AGF do not provide patients with improved clinical outcomes, anticipated sales of our AGF related products may never materialize. Our success in selling our AGF related products will depend, in large part, on the medical community's acceptance of AGF. The medical community's acceptance of AGF will depend upon our ability to demonstrate the efficacy of AGF and its advantages, favorable clinical performance and cost-effectiveness. We cannot predict whether the medical community will accept AGF or, if accepted, the extent of its use. If long-term studies or clinical experience indicate that AGF causes negative effects, we could be subject to significant liability. Our strategy to increase sales of AGF is to market these products primarily to our spinal implant customers. There is no assurance that the strategy will work, however, and no assurance that sales of our AGF related products will increase. 14 We face risks related to the upgrading and expansion of our distribution network. We expect to continue to rely on independent agents for the domestic distribution of both orthobiologic and spinal implant products. Independent commissioned sales agents may represent other medical devices for a variety of manufacturers and may not dedicate enough time or attention to selling our products. Furthermore, we expend significant resources to train and educate new independent agents about our products and our marketing programs. Our ability to recruit independent sales agents has been aided by some of our competitors' replacement of independent agents with direct sales representatives. However, our competitors may not continue to utilize direct sales representatives and we can therefore give no assurance that we will continue to be able to attract new or retain our current independent sales agents. There can be no assurance that we will be able to develop an effective distribution network or that our sales force will be able to continue to increase sales or maintain current sales levels of our products. Product introductions or modifications may be delayed or canceled as a result of the FDA regulatory process, which could cause our sales to decline. The medical devices we manufacture and market are subject to rigorous regulation by the FDA and numerous other federal, state and foreign governmental authorities. Our failure to comply with such regulations could lead to the imposition of injunctions, suspensions or loss of regulatory approvals, product recalls, termination of distribution, or product seizures. In the most egregious cases, criminal sanctions or closure of our manufacturing facility are possible. The process of obtaining regulatory approvals to market a medical device, particularly from the FDA, can be costly and time-consuming, and there can be no assurance that such approvals will be granted on a timely basis, if at all. The regulatory process may delay the marketing of new products for lengthy periods and impose substantial additional costs or it may prevent the introduction of new products altogether. In particular, the FDA permits commercial distribution of a new medical device only after the FDA has cleared a 510(k) premarket notification or has approved a Premarket Approval application, or PMA, for such device. The FDA will clear marketing of a medical device through the 510(k) process if it is demonstrated that the new product is substantially equivalent to other 510(k)-cleared products. The PMA approval process is more costly, lengthy and uncertain than the 510(k) premarket notification process. There can be no assurance that any new products we develop will be subject to the shorter 510(k) clearance process and therefore significant delays in the introduction of any new products that we develop may occur. We anticipate that our products that are in final development will be eligible for the 510(k) premarket notification process. If the FDA does not clear marketing of our products in final development through the 510(k) clearance process, we will be forced to comply with the PMA approval process in order to obtain FDA approval for these products. If we choose to go through the PMA approval process, there will be significant costs and delays in the introduction of our new products, if they are approved at all. Moreover, foreign governmental authorities have become increasingly stringent and we may be subject to more rigorous regulation by foreign governmental authorities in the future. Any inability or failure of our foreign independent distributors to comply with the varying regulations or the imposition of new regulations could restrict such distributors' ability to sell our products internationally and thereby adversely affect our business. All products and manufacturing facilities are subject to continual review and periodic inspection by the FDA. The discovery of previously unknown problems with our company or our products or facilities may result in product labeling restrictions, recall, or withdrawal of the products from the market. In addition, the FDA actively enforces regulations prohibiting the promotion of medical devices for unapproved indications. If the FDA determines that we have marketed our products for off- label use, we could be subject to fines, injunctions or other penalties. 15 We may be subject to product liability claims and our limited product liability insurance may not be sufficient to cover the claims, or we may be required to recall our products. We manufacture medical devices that are used on patients in surgical procedures, and we may be subject to product liability claims and product recalls. The spinal implant industry has been historically litigious and we face an inherent business risk of financial exposure to product liability claims. Since our spinal products are often implanted in the human body, manufacturing errors or design defects could result in injury or death to the patient, and could result in a recall of our products and substantial monetary damages. Any product liability claim brought against us, with or without merit, could result in an increase to our product liability insurance premiums or our inability to secure coverage in the future. We would also have to pay any amount awarded by a court in excess of our policy limits. In addition, any recall of our products, whether initiated by us or by a regulatory agency, may result in adverse publicity for us that could have a material adverse effect on our business, financial condition and results of operations. Our product liability insurance policies have various exclusions, and we may be subject to a product liability claim or recall for which we have no insurance coverage, in which case we may have to pay the entire amount of the award or costs of the recall. Finally, product liability insurance is expensive and may not be available in the future on acceptable terms, or at all. We may face challenges to our patents and proprietary rights. We rely on a combination of patents, trade secrets and nondisclosure agreements to protect our proprietary intellectual property. Our patent positions and those of other medical device companies are uncertain and involve complex and evolving legal and factual questions. There can be no assurance that pending patent applications will result in issued patents, that patents issued to or licensed by us will not be challenged or circumvented by competitors or that such patents will be found to be valid or sufficiently broad to protect our technology or to provide us with any competitive advantage. Third parties could also obtain patents that may require licensing for the conduct of our business, and there can be no assurance that the required licenses would be available. We also rely on nondisclosure agreements with certain employees, consultants and other parties to protect, in part, trade secrets and other proprietary technology. There can be no assurance that these agreements will not be breached, that we will have adequate remedies for any breach, that others will not independently develop substantially equivalent proprietary information or that third parties will not otherwise gain access to our trade secrets and proprietary knowledge. 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 result in a decrease in our market share and profits. The medical product industry is characterized by frequent and substantial intellectual property litigation and competitors may resort to intellectual property litigation as a means of competition. Intellectual property litigation is complex and expensive, and the outcome of such litigation is difficult to predict. Any future litigation, regardless of the outcome, could result in substantial expense and significant diversion of the efforts of our technical and management personnel. Litigation may also be necessary to enforce our patents and license agreements, to protect our trade secrets or know-how or to determine the enforceability, scope and validity of the proprietary rights of others. An adverse determination in any such proceeding could subject us to significant liabilities to third parties, or require us to seek licenses from third parties or pay royalties that may be substantial. Accordingly, an adverse determination in a judicial or administrative proceeding or failure to obtain necessary licenses could prevent us from manufacturing or selling certain of our products which in turn would have a material adverse effect on our business, financial condition and results of operations. 16 Possible denial of third-party reimbursement could materially adversely affect our future business, results of operations and financial condition. In the United States, our products are purchased by hospitals, who are reimbursed for the devices provided to their patients by third-party payors, such as governmental programs (e.g., Medicare and Medicaid), private insurance plans and managed care programs. These third-party payors may deny reimbursement if they determine that a device used in a procedure was not used in accordance with cost-effective treatment methods, as determined by the third- party payor, or was used for an unapproved indication. Also, third-party payors are increasingly challenging the prices charged for medical products and services. In international markets, reimbursement and healthcare payment systems vary significantly by country and many countries have instituted price ceilings on specific product lines. There can be no assurance that our products will be considered cost-effective by third-party payors, that reimbursement will be available or, if available, that the third-party payors' reimbursement policies will not adversely affect our ability to sell our products profitably. We are dependent on our suppliers and the loss of any of these suppliers could adversely affect our business. We do not machine the components for our spinal implants or instruments; rather, we are dependent upon several suppliers for the machining of such components. Also, the UltraConcentrator, one of our products used to collect AGF, is manufactured under an exclusive supply agreement with a vendor that itself has a sole source of supply for filter material, a key component of the UltraConcentrator. In the event that we are unable to obtain components for any of our products, or obtain such components on commercially reasonable terms, we may not be able to manufacture or distribute our products on a timely and competitive basis, or at all. Any delays in product availability or costs incurred in locating alternative suppliers could have a material adverse effect on our operations. The harvesting of coral is subject to regulation which could affect our ability to obtain sufficient quantities of coral in the future. The harvesting and import of the coral used for our coral-based orthobiologic products must comply with the requirements of the Convention on International Trade of Endangered Species of Wild Fauna and Flora. As a result, we must register and obtain licensure from the U.S. Department of Fish and Wildlife for both the import of raw coral and the export of finished product. In the future, regulations could make the import or export of coral or coral-derived products prohibitive and could interrupt our ability to supply product. We cannot assure you that our supply of raw coral is sufficient, that we will be able to obtain sufficient quantities of coral in the future or that future regulations will not prohibit its use altogether. 17 Our business could be materially adversely impacted by risks inherent in international markets. In 2000, approximately 20% of our sales were generated outside the United States. We expect that such sales will continue to account for a significant portion of our revenue in the future. Our international sales subject us to other inherent risks, including the following: . fluctuations in currency exchange rates; . regulatory, product approval and reimbursement requirements; . tariffs and other trade barriers; . greater difficulty in accounts receivable collection and longer collection periods; . difficulties and costs of managing foreign distributors; . reduced protection for intellectual property rights in some countries; . burdens of complying with a wide variety of foreign laws; . the impact of recessions in economies outside the United States; . political and economic instability; and . seasonal reductions in business activity during the summer months in Europe and other parts of the world. If we fail to successfully market and sell our products in international markets, our business, financial condition, results of operations, and cash flows could be materially and adversely affected. Future acquisitions could adversely affect our operations or financial results. From time to time, we consider acquisition of technology product lines or businesses to supplement our current product offering. Any such future acquisitions involve risks such as the following: . we may be exposed to unknown liabilities of acquired companies; . our acquisition and integration costs may be higher than we anticipated and may cause our quarterly and annual operating results to fluctuate; . we may experience difficulty and expense in assimilating the operations and personnel of the acquired businesses, disrupting our business and diverting management's time and attention; and . our relationships with key customers of acquired businesses may be impaired, due to changes in management and ownership of the acquired businesses. 18 Item 2. Properties We are headquartered in Irvine, California where we lease a 35,528 square foot facility. The annual average lease expense over the ten year term of the lease, which expires January 31, 2003, is $387,000. The lease provides a right to extend the term for an additional five years at the fair market lease rate of the facility on the extension date, but not less than the rate we paid during the month immediately preceding the commencement of the extension period. We also lease a 2,700 square foot warehouse facility in Santa Ana, California, a 4,274 square foot facility in Irvine, California to provide additional warehousing, laboratory and office space, an 1,800 square foot prototype machine shop in Irvine, California and a sales office with approximately 200 square feet in Miami, Florida. We believe our current facilities will be adequate to serve our operational needs through 2001. We also lease a 27,680 square foot facility in Dublin, Ohio that is vacant. The facility formerly contained the Cross Medical Products offices and operation until Cross' merger with us and consolidation of their operations into our headuarters facility. The lease term began on April 1, 1996 and terminates on June 1, 2001. Item 3. Legal Proceedings On September 5, 2000, our wholly-owned subsidiary, Cross, filed suit in the U.S. District Court, Central District of California, against Depuy AcroMed, Inc., a Johnson & Johnson company and Biedermann Motech GmbH, which alleges that Depuy Acromed has infringed and continues to infringe Cross' U.S. Patent Nos. 5,466,237 and 5,474,555. These patents relate to the VLS or Variable Locking Screw technology embodied in certain components of our Synergy Spinal System. The Complaint seeks damages for willful past and continuing infringement of the patents. The Complaint also seeks a declaratory judgment against Depuy Acromed and Biedermann Motech that Cross is not infringing Biedermann Motech's patent no. 5,207,678. Depuy AcroMed has responded to the Complaint denying all claims, alleging that Cross' patents are invalid and unenforceable, and alleging that it does not infringe. Aside from the patent litigation, the nature of our business subjects us to products liability and various other legal proceedings from time to time. We are currently involved in legal proceedings incidental to the normal conduct of our business. We do not believe that any liabilities relating to the legal proceedings to which we are a party are likely to be, individually or in the aggregate, material to our consolidated financial condition or results of operations. Item 4. Submission of Matters to a Vote of Security Holders None. 19 PART II Item 5. Market for Registrant's Common Stock and Related Stockholder Matters Our common stock commenced trading on the Nasdaq National Market under the symbol "BONZ" on December 20, 1993.

Net sales from the dental business were approximately $7.1 million and $1.7 million in 1996 and 1997, respectively. /(2)/ Amount includes $5.0 million of non-recurring charges related to the May 1998 merger with Cross, the subsequent restructuring associated with the closing of the Dublin, Ohio facility and the relocation of employees and assets from Dublin to Irvine, California. /(3)/ In 1996, 1997, 1998 and 1999, we recognized deferred tax assets of $683,000, $2.0 million, $211,000 and $1.6 million, respectively, which had previously been fully reserved in accordance with Statement of Financial Accounting Standards No. 109. 21 Item 7. Management's Discussion and Analysis of Results of Operations and Financial Condition Financial Overview Our revenues are generated from the sale of products in two principal product categories--spinal implant products and orthobiologic products. Our spinal implant products consist of titanium or stainless steel hooks, rods, plates, spacers and screws and related instruments required for the surgeon to assemble a construct which restores the natural anatomy of the spine, keeping it immobilized while a bone graft eventually fuses the vertebrae. Our orthobiologic products consist of synthetic bone graft substitute materials and products used to derive AGF. AGF is used to provide faster, more complete bone growth and enhance the performance of our bone graft products. In May 1998, we merged with Cross Medical Products, Inc., combining our orthobiologics expertise and product offering with Cross' spinal implant expertise and products. The merger was accounted for as a pooling-of-interests, and all financial information related to periods prior to the merger was restated to reflect the financial information of both companies as if we had always been a combined entity. All of our operations are located in the United States, however, we sell our products to customers both within and outside the United States. In 2000, our domestic sales were 80% of total sales and our international sales were 20% of total sales. Within the United States, we distribute our products primarily through independent agents. These independent agents provide a delivery and consultative service to our surgeon and hospital customers and receive commissions based on sales in their territories. The commissions are reflected in our income statement within selling and marketing expense. For our spinal implant products, we invoice hospitals directly following a surgical procedure in which our products are used. Our spinal implant products are made available to hospitals from consignment inventories maintained by our larger independent agents, or from loaner implant sets that we ship from our facility. For our orthobiologic products, we generally ship directly to hospitals from our facility, and we invoice hospitals upon shipment. Outside the United States, we sell our products directly to distributors who maintain an inventory of our products. We record revenue at the time of shipment to the distributor at prices generally ranging from 40% to 70% of our U.S. list prices. The distributors service the surgeons and hospitals, deliver products and invoice hospitals directly at prices determined by the distributors. Because our revenues from U.S. hospitals are primarily at list price, and our revenues from international distributors are at a discount to U.S. list prices, our overall gross margin is subject to fluctuation based on our domestic versus international sales mix, with domestic gross margins being somewhat higher than international gross margins. Additionally, the mix between spinal implant sales and orthobiologic sales also affects our gross margins, with higher margins in orthobiologics. 22 Results of Operations The following table presents our results of operations as percentages: Percentage of Net Sales Percentage Change Year ended December 31, ------------------------ ------------------------------------------ 1999 vs. 2000 vs. 1998 1999 2000 1998 1999 ---------- -------- --------- --------- --------- Net sales ........................................ 100.0% 100.0% 100.0% 28.6% 14.1% Cost of goods sold ............................... 28.3 30.0 30.4 36.2 15.6 ---------- -------- --------- --------- --------- Gross profit ................................... 71.7 70.0 69.6 25.7 13.4 ---------- -------- --------- --------- --------- Operating expenses: Research and development ....................... 12.1 10.7 12.0 14.9 26.5 Selling and marketing .......................... 39.1 36.0 35.7 18.2 13.3 General and administrative ..................... 13.4 11.2 8.7 7.8 (11.5) Merger-related expenses ........................ 10.0 - - - - Restructuring charges .......................... 5.0 - - - - Non-recurring charges .......................... 1.6 - .6 - - ---------- -------- --------- --------- --------- Total operating expenses .................... 81.2 57.9 57.0 (8.2%) 12.1 ---------- -------- --------- --------- --------- Income (loss) from operations...............

The following table presents sales by category (in thousands): Year ended December 31, Change -------------------------------- -------------------------------- 1999 2000 Amount Percent ---------- ----------- ------------ ------------- Spinal implant product sales ......................... $20,807 $23,702 $2,895 13.9% Orthobiologic product sales .......................... 18,049 20,617 2,568 14.2 ------- ------- ------ ------- Total sales ........................................ $38,856 $44,319 $5,463 14.1% ======= ======= ====== ======= Sales of spinal implant products increased in the year ended December 31, 2000 by $2.9 million, or 13.9%, to $23.7 million, compared to $20.8 million for the year ended December 31, 1999. We estimate that the growth rate closely matched the overall growth rate of the market for spinal implants. Sales of orthobiologic products increased by $2.5 million, or 14.2%, to $20.6 million for the year ended December 31, 2000, compared to $18.1 million for the year ended December 31, 1999. AGF related products, which were launched on a nationwide basis during the second quarter of 1999, increased by $3.5 million or 128% to $6.3 million for the year ended December 31, 2000 compared to $2.8 million in 1999. Sales of synthetic bone products decreased $1.0 million or 6.6% to $14.2 million versus $15.2 million in 2000. We believe the decline in sales of synthetic bone products has resulted from our deliberate transition of sales and distribution focus to spinal procedures since our merger with Cross in 1998. While this shift has benefited our spinal implant product sales, we believe it has also resulted in a reduction in sales of synthetic bone products for non-spine procedures such as trauma and revision total joints. We intend to explore supplemental distribution alternatives in 2001 with the goal of recapturing lost sales in non-spine procedures, but there can be no assurance that our efforts will be successful. Total domestic sales of spinal products and orthobiologic products increased 17.9%, or $5.4 million, to $35.5 million for the year ended December 31, 2000, compared to $30.1 million for the same period of 1999. International sales were essentially unchanged at $8.8 million for the years ended December 31, 1999 and 2000. For the year ended December 31, 2000, gross margin as a percentage of sales was 69.6%, compared to 70.0% for the year ended December 31, 1999. 23 Total operating expenses for the year ended December 31, 2000 increased by $2.7 million, or 12.1%, to $25.3 million, compared to $22.5 million during the same period of 1999. Research and development expenses in 2000 increased by 26.5%, or $1.1 million, due primarily to salaries for additional engineers hired for development projects along with associated supply expenses and consulting fees. Selling and marketing expenses in 2000 increased $1.9 million, or 13.3%, compared to 1999, primarily due to increased commissions on higher domestic sales in 2000. General and administrative expenses decreased by $499,000, or 11.5%, in 2000, primarily as the result of decreased corporate bonus expense and lower product liability insurance premiums as a result of more favorable rates. During the second quarter of 2000, a non-recurring charge of $268,000 was recorded in connection with the withdrawal of a proposed secondary public stock offering. Total interest and other income increased $476,000, or 92.4%, to $991,000 for the year ended December 31, 2000, compared to $515,000 during the same period of 1999, as higher average cash, cash equivalents and short-term investment balances in 2000 increased interest income and the elimination of long-term debt in 2000 reduced interest expense. The effective tax rates for 1999 and 2000 were 7.8% and 37.3%, respectively. During 1999, the income tax provision was partially offset by the elimination of the valuation allowance against our deferred tax assets, resulting in the comparatively lower effective rate. Year Ended December 31, 1999 Compared to Year Ended December 31, 1998 For the year ended December 31, 1999, sales of $38.9 million were $8.6 million, or 28.6%, higher than sales of $30.2 million for the previous year. The following table presents sales by category (in thousands): Year ended December 31, Change ------------------------------------ ------------------------------------ 1998 1999 Amount Percent --------------- --------------- --------------- --------------- Spinal implant product sales .................. $15,367 $20,807 $5,440 35.4% Orthobiologic product sales ................... 14,842 18,049 3,207 21.6 --------------- --------------- --------------- --------------- Total sales ................................. $30,209 $38,856 $8,647 28.6% =============== =============== =============== =============== Sales of spinal implant products increased in the year ended December 31, 1999 by $5.4 million, or 35.4%, to $20.8 million, compared to $15.4 million for the year ended December 31, 1998. The increase reflects continued market penetration of the Synergy Spinal System, aided by improved distribution and territory coverage. Sales of orthobiologic products increased by $3.2 million, or 21.6%, to $18.0 million for the year ended December 31, 1999, compared to $14.8 million for the year ended December 31, 1998. Our new AGF related products, which were launched on a nationwide basis during the second quarter of 1999, accounted for $2.8 million of orthobiologic products sales during 1999. Sales of synthetic bone products remained relatively level for the two periods. Total domestic sales of spinal products and orthobiologic products increased 30.2%, or $7.0 million, to $30.1 million for the year ended December 31, 1999, compared to $23.1 million for the same period of 1998. International sales increased $1.6 million, or 23.4%, to $8.7 million for the year ended December 31, 1999, compared to $7.1 million for the same period of 1998. For the year ended December 31, 1999, gross margin as a percentage of sales was 70.0%, compared to 71.7% for the year ended December 31, 1998. Spine products sales, which have a lower gross margin than orthobiologic products sales, comprised a greater percentage of total sales in 1999 than in 1998. 24 Total operating expenses for the year ended December 31, 1999 decreased by $2.0 million, or 8.2%, to $22.5 million, compared to total operating expenses of $24.5 million during the same period of 1998. Excluding merger related expenses, restructuring charges and non-recurring charges recorded in 1998, operating expenses increased $3.0 million, or 15.4%, but decreased as a percentage of sales from 64.6% in 1998 to 57.9% in 1999. Research and development expenses in 1999 increased by 14.9%, or $542,000, due primarily to salaries for additional engineers hired for spinal implant development projects. Selling and marketing expenses in 1999 increased $2.2 million, or 18.2%, compared to 1998, primarily due to increased commissions on higher domestic sales in 1999 and the hiring of additional sales and marketing staff. General and administrative expenses increased by $316,000, or 7.8%, in 1999, primarily as the result of increased corporate bonus expense and higher product liability insurance premiums resulting from increased sales offset partially by a decrease in property taxes resulting from the closure of the Ohio facility. Total interest and other income were approximately the same in the two periods, as reduced interest income on lower average cash, cash equivalents and short-term investments balances in 1999 was mostly offset by reduced interest expense. We had lower average cash, cash equivalents and short-term investments balances in 1999 compared to 1998 due to the payment of merger-related expenses, restructuring charges and non-recurring charges, the repurchase of 605,000 shares of our common stock and the redemption of convertible debentures. Interest expense was lower in 1999 than in 1998 due primarily to the write-off of prepaid debt issuance costs associated with convertible debentures which were redeemed during 1998. This redemption also lowered interest expense in 1999. In 1998, despite a pre-tax loss, taxable income was recognized as a result of some disallowed merger cost deductions. This coupled with the reduction of the valuation allowance resulted in a net tax provision of $59,000. In 1999, our increased profitability eliminated the remaining valuation allowance against our deferred tax assets. This resulted in the need to record an income tax provision for the year ended December 31, 1999 at an effective tax rate of approximately 7.8%. Liquidity and Capital Resources In 2000, our operations generated positive cash flow of approximately $4.4 million. Another significant source of cash in 2000 was $1.5 million in proceeds from the exercise of stock options. We invest our excess cash in U.S. Treasury securities and high-grade marketable securities. At December 31, 2000, cash, cash equivalents and short-term investments totaled $14.6 million, up $4.8 million from $9.8 million at December 31, 1999. We also have a $5.0 million revolving line of credit available to us that had no amount outstanding at December 31, 2000 and which expires in June 2001. We currently intend to seek an extension of that facility. We have used and may continue to use our cash, our common stock, or a combination of both to pay for purchased technologies, product lines, mergers and acquisitions. We also intend to continue to invest in the development of our business. We believe we currently possess sufficient resources to meet the cash requirements of our operations for at least the next year. However, some of the aforementioned activities may require cash in excess of that which we currently possess, and we can give no assurance that we will be able to raise the additional capital on satisfactory terms, if at all. At December 31, 2000, we had no material commitments for capital expenditures. 25 Item 7a. Quantitative and Qualitative Disclosures About Market Risk We are exposed to market risk for changes in interest rates related primarily to our cash and cash equivalent balances and marketable securities. However, as all of our investments are in short-term instruments, we believe that we have no material market risk exposure. Item 8.

F-6 INTERPORE INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2000 1. Summary of Significant Accounting Policies Organization and Description of Business Interpore International, Inc. ("Interpore"), doing business as Interpore Cross International ("Interpore Cross") operates in one business segment: the design, manufacture and marketing of medical devices for the orthopedic marketplace. The products are distributed in the United States and internationally. Basis of Presentation The accompanying consolidated financial statements include the accounts of Interpore Cross and its subsidiaries after elimination of all significant intercompany transactions. In May 1998, Interpore merged with Cross Medical Products, Inc. ("Cross"), a publicly traded Ohio-based worldwide supplier of spinal implant systems used to treat degenerative conditions and deformities of the spine. This merger has been accounted for as a pooling-of-interests. Certain amounts have been reclassified to conform to the 2000 presentation. Revenue Recognition Revenue from sales of product where the customer immediately accepts title is recorded at the time of shipment. Revenue from sales of consigned inventory is recorded upon receipt of written acknowledgement from sales agents or customers that the product has been used in a surgical procedure. Provision is made currently for estimated product returns based on historical experience and other known factors. In December 1999, the Securities and Exchange Commission released Staff Accounting Bulletin No. 101, Revenue Recognition in Financial Statements, ("SAB 101"). This bulletin summarizes certain views of the SEC staff on applying generally accepted accounting principles to revenue recognition in financial statements and states that revenue is realized or realizable and earned only when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred or services have been rendered; the seller's price to the buyer is fixed and determinable; and collectibility is reasonably assured. In meeting the criterion that delivery has occurred or services have been rendered, the SEC staff indicates that customer acceptance must be obtained before revenue recognition is appropriate in situations where customer acceptance is a contract requirement. This applies without consideration of the significance or cost of any post-shipment services that must be performed to obtain such customer acceptance. Interpore Cross' current revenue recognition policies are consistent with criteria summarized in SAB101. F-7 INTERPORE INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Per Share Information Basic earnings per share (EPS) is calculated by dividing net earnings by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the assumed conversion of all dilutive securities, consisting of employee stock options, convertible securities and warrants. The following table presents the computation of net income (loss) per share (in thousands, except per share data): Year ended December 31, ------------------------------------------------------------ 1998 1999 2000 --------------- --------------- --------------- Net income (loss) ............................................... $(2,424) $ 4,798 $ 4,133 =============== =============== =============== Shares used in computing net income (loss) per share--basic Weighted average common shares outstanding .................... 13,904 13,506 14,043 Effect of dilutive securities: Weighted average convertible preferred stock .................. - /(1)/ 31 6 Common share equivalents outstanding .......................... - /(1)/ 339 1,091 --------------- --------------- --------------- Shares used in computing net income (loss) per share--diluted ... 13,904 13,876 15,140 =============== =============== =============== Basic earnings per share ........................................ $ (.17) $ .36 $ .29 Diluted earnings per share ...................................... $ (.17) $ .35 $ .27 - --------------- /(1)/Effect would have been anti-dilutive, accordingly, the amounts are excluded from shares used in computing diluted earnings per share. Weighted average convertible preferred stock would have been 33 shares and common share equivalents outstanding would have been 346 shares. Shares issuable from the convertible subordinated debentures were excluded from the calculation of diluted earnings per share in all years because the effect would have been anti-dilutive. Concentrations of Business and Credit Risk Interpore Cross operates in worldwide markets which are subject to rapid technological advancement and significant government regulation. The introduction of technologically advanced products by competitors and increased regulatory or trade barriers could have a material impact on the future operations of Interpore Cross. In the normal course of business, Interpore Cross provides credit to its customers. At December 31, 2000, 61% of Interpore Cross' accounts receivable are from domestic customers and 39% are from foreign customers. Interpore Cross performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses which, when realized, have been within the range of management's expectations. Sales to domestic customers were 77%, 78% and 80% of total sales in 1998, 1999 and 2000, respectively, and sales to foreign customers were 23%, 22% and 20% of total sales in 1998, 1999 and 2000, respectively. All sales to foreign customers for the periods presented were denominated in United States dollars. In the U.S., there are no significant customer concentrations, as Interpore Cross invoices hospitals directly for product used or shipped. However, in the international markets, Interpore Cross has one significant distributor that accounted for approximately 24% of its 2000 international sales and 5% of its 2000 worldwide sales. F-8 INTERPORE INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Some of the products and materials supplied by Interpore Cross' vendors are currently sole-sourced, but the Company believes that it could locate alternative vendors for supply of these components. However, the UltraConcentrator, one of the products used to collect AGF(TM), is manufactured under an exclusive supply agreement with a vendor that itself has a sole source of supply of the contained filter material. Although the filter material is not readily available through alternative sources, Interpore Cross believes that there are suppliers that could supply alternate materials with probable equivalent function. In the event that a re-engineering of the product were necessary due to an interruption in supply from our current vendor, delays in product availability could occur and significant costs could be incurred, both of which would have a material adverse effect on Interpore Cross' operations. Stock Option Plans Interpore Cross accounts for stock compensation to employees using the intrinsic value method provided for by Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees and related interpretations, and provides supplementary disclosures in the notes to the consolidated financial statements of the differences between using this method and the fair value method as required by Statement of Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation. Advertising Interpore Cross expenses as incurred the costs of advertising which totaled $201,000, $219,000 and $198,000 for the years ended December 31, 1998, 1999 and 2000, respectively. Research and Development Expenditures for research and development are expensed as incurred. Cash, Cash Equivalents and Short-term Investments Interpore Cross invests excess cash in United States Treasury securities and high grade marketable securities. Highly liquid investments with a maturity of three months or less at the date of purchase are classified as cash equivalents. Short-term investments consist of highly liquid investments with a maturity of more than three months when purchased. Pursuant to Statement of Financial Accounting Standards No. 115, Accounting for Certain Investments in Debt and Equity Securities, Interpore Cross' short-term investments are classified as available-for-sale securities and are reported at fair market value. Inventories Inventories are stated at the lower of first-in, first-out average cost or market. Inventories are comprised of the following (in thousands): December 31, ------------------------------------ 1999 2000 --------------- --------------- Raw material ............................... $ 1,159 $ 1,202 Work-in-process ............................ 442 575 Finished goods ............................. 11,469 10,708 --------------- --------------- $13,070 $12,485 =============== =============== F-9 INTERPORE INTERNATIONAL, INC.

Lesser of estimated useful life or term of lease Intangible Assets Intangible assets include patents and license rights. The patents and license rights are amortized on a straight-line basis over their useful lives. Amortization begins at the time the patents are issued. Management periodically evaluates the recoverability of intangible assets based on undiscounted future cash flows. Amortization expense for the years ended December 31, 1998, 1999 and 2000 was $75,000, $113,000 and $249,000, respectively. Accumulated amortization of intangible assets was $197,000 and $446,000 at December 31, 1999 and 2000, respectively. Consolidated Statements of Cash Flows Interpore Cross paid income taxes of $1,053,000, $163,000 and $1,968,000 and interest of $416,000, $294,000 and $152,000 in 1998, 1999 and 2000, respectively. Long-Lived Assets In accordance with Statement of Financial Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets, Interpore Cross reviews long-lived assets and certain intangibles whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Interpore Cross believes no impairment of the carrying value of its long-lived assets existed at December 31, 2000. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. F-10 INTERPORE INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Recent Accounting Pronouncements In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities ("SFAS 133). SFAS 133 is effective for fiscal years beginning after June 15, 2000. SFAS 133 requires that all derivative instruments be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income (loss) depending on whether a derivative is designed as part of a hedge transaction and, if so, the type of hedge transaction involved. Interpore Cross does not expect that adoption of SFAS 133 will have a material impact on its consolidated financial position or results of operations. 2. Business Combination The merger of Interpore and Cross was approved by the stockholders of both companies on May 6, 1998 and became effective on May 7, 1998. Shareholders of Cross received 1.275 shares of Interpore common stock for each share of issued and outstanding Cross common stock. Accordingly, Interpore issued 6.7 million shares of its common stock to Cross shareholders in exchange for all of the outstanding common stock of Cross. In addition, approximately 895,000 shares of Interpore Cross common stock were reserved for issuance upon the exercise of assumed Cross stock options. The merger was accounted for as a pooling-of- interests. During the second quarter of 1998, Interpore Cross recorded merger-related expenses and restructuring charges of $3.0 million and $1.5 million, respectively. The merger-related expenses included legal, accounting and administrative costs incurred in connection with the merger of Interpore and Cross. The restructuring charges were associated with the closing of the Dublin, Ohio facility and included severance benefits for 23 employees not remaining with Interpore Cross, the write-off of fixed assets which were not transferred to Interpore Cross' Irvine, California headquarters, and the accrual of remaining lease payments for the Dublin facility. During the third and fourth quarters of 1998, Interpore Cross recorded $474,000 of non-recurring charges related to the relocation of assets and employees from the Dublin, Ohio facility to the Irvine, California headquarters. Restructuring costs and related liabilities for the two years in the period ended December 31, 2000 are summarized below (in thousands): Remaining Severance lease benefits payments Total --------------- --------------- --------------- Accrued restructuring costs at December 31, 1998............................................ $284 $425 $709 1999 payments.................................................. 196 189 385 --------------- --------------- --------------- Accrued restructuring costs at December 31, 1999............................................ 88 236 324 2000 payments.................................................. 88 175 263 --------------- --------------- --------------- Accrued restructuring costs at December 31, 2000............................................ $ - $ 61 $ 61 =============== =============== =============== Interpore Cross expects that the accrued restructuring costs of $61,000 at December 31, 2000 is adequate to cover remaining exposures and will be paid over the next 6 months.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Selected financial information for the combining entities included in the consolidated statements of operations for the four months ended April 30, 1998 are as follows (in thousands): For the period ended April 30, 1998 ------------------------ Net sales Interpore............................................................................... $4,664 Cross................................................................................... 4,647 ------------------ Combined................................................................................. $9,311 ================== Net income Interpore............................................................................... $ 770 Cross................................................................................... 74 ------------------ Combined................................................................................. $ 844 ================== 3. Acquisition of AGF Technology In December, 1999, Interpore Cross purchased all the intellectual property of Quantic Biomedical, Inc. which included the patents and technology for making AGF. The purchase price of $1.9 million included a cash payment of $500,000, 100,000 unregistered shares of Interpore Cross common stock with a fair market value of $551,000 and 200,000 stock purchase warrants which vest over a two-year period at exercise prices ranging from $7.13 to $8.63 with a fair market value of $659,000. Additionally, previously paid unamortized license fees of $167,000 were reallocated to the purchase price. The total purchase price has been recorded as an intangible asset and is being amortized over a ten-year period. 4. Fair Value of Financial Instruments The estimated fair value of financial instruments is as follows (in thousands): December 31, 1999 December 31, 2000 ------------------------------------ ------------------------------------ Carrying Fair Carrying Fair Amount Value Amount Value --------------- --------------- --------------- --------------- Assets: Cash and cash equivalents ......................... $6,315 $6,315 $14,610 $14,610 Short-term investments ............................ 3,459 3,459 - - Liabilities: Long-term debt .................................... $3,152 $3,897 $ - $ - Due to the short-term nature of cash, cash equivalents and short-term investments, the carrying amount approximates the fair value. The fair value of the long-term debt, consisting of Convertible Subordinated Debentures, is based upon the greater of the fair market value of Interpore Cross common stock into which the Debentures are convertible, or the carrying amount. F-12 INTERPORE INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) 5. Long-Term Obligations Long-term obligations consisted of the following (in thousands): December 31, ------------------------------------- 1999 2000 --------------- ---------------- Convertible Subordinated Debentures, due in June 2003 plus interest at 8.5%, payable semi-annually ................................................. $3,152 $ - Obligations under capital leases ............................................. 28 10 --------------- ---------------- 3,180 10 Less current maturities ...................................................... 15 10 --------------- ---------------- $3,165 $ - =============== ================ The 8.5% Convertible Subordinated Debentures (the "Debentures") due June 1, 2003 were convertible at any time before maturity, unless previously redeemed, into shares of Interpore Cross common stock at a conversion price of $6.37 per share. Pursuant to the terms of the underlying indenture, upon the merger of Interpore and Cross, Debenture holders were allowed to request redemption until June 26, 1998 at 101% of the principal amount thereof, plus accrued interest. Requests for redemption totaling $1.8 million were made. During 1998, $97,000 of Debentures were converted into 15,221 shares of Interpore Cross common stock. There were no conversions recorded in 1999. On June 14, 2000, Interpore Cross notified the holders that the Debentures would be redeemed, if not earlier converted, effective August 1, 2000. For the current period through August 1, 2000, Debentures totaling $3.0 million were converted into 470,000 shares of common stock, and $155,000 of the Debentures were redeemed. The fair value of the Debentures was approximately $3.9 million at December 31, 1999. Amortization of offering costs, related to the issuance of the Debentures, of $206,000, $48,000 and $25,000 for the years ended December 31, 1998, 1999 and 2000, respectively, is included in interest expense. Interpore Cross has available a $5 million line of credit facility with its primary bank. The line is secured by substantially all of the assets of Interpore Cross, bears interest at the bank's prime rate (9.5% at December 31, 2000), and matures June 2001. The facility contains certain financial covenants with which Interpore Cross was in compliance at December 31, 2000. No amount was outstanding under the facility at December 31, 2000. 6. Stockholders' Equity Series E Convertible Preferred Stock On March 1, 2000, Interpore Cross common stock closed above $10.00 for the twentieth day out of 30 consecutive trading days and accordingly, as provided in the Series E Preferred Stock Agreement, all of the outstanding Series E Preferred Stock converted into common stock. Stock Options Interpore Cross has seven stock option plans that provide for the granting of incentive stock options or non-qualified stock options to officers, key employees, directors and consultants. The 1995 Stock Option Plan (the "1995 Plan"), the Stock Option Plan for Non-Employee Directors (the "Directors Plan"), the 1999 Consultants Stock Option Plan (the "Consultants Plan") and the 2000 Equity Participation Plan (the "2000 Plan") are the only plans with stock option awards available for grant. The other three plans have either expired or have been terminated with respect to future option grants, but have options outstanding and exercisable at December 31, 2000. Options outstanding under Interpore Cross' seven stock option plans generally vest over a four- or five- year period, and expire either six years or ten years from the date of grant. F-13 INTERPORE INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) At December 31, 2000 there were 123,375 shares available for grant under the 1995 Plan, all of which may be granted in 2001.

The purchase price for the shares is 85% of the lesser of the fair market value of such shares on the first or last day of each six-month period. The plan provides for a maximum of 300,000 shares to be issued pursuant to the plan. As of December 31, 2000, 106,877 shares of common stock had been issued pursuant to the plan. Stockholder Rights Plan Under Interpore Cross' Stockholder Rights Plan, every share of Interpore Cross common stock currently issued or to be issued is accompanied by one right, and every common share issued upon conversion of Interpore Cross preferred stock also will be accompanied by one right. The plan provides for the rights to become exercisable upon the earlier to occur of (i) ten days following the announcement that a person or group of persons has acquired or obtained the right to acquire 15% or more of Interpore Cross common stock, or (ii) ten days following the announcement or commencement of a tender offer which would result in ownership of 15% or more of the common stock. If any person or group of persons acquires 15% or more of Interpore Cross common stock, each right, once exercisable and excluding any rights acquired by the 15% holder, will entitle its holder to purchase that number of additional shares of Interpore Cross common stock having a market value of twice the rights' exercise price. If Interpore Cross is involved in a merger or other business combination involving the exchange of Interpore Cross common stock for stock of an acquiring company at any time after the rights become exercisable, each right will entitle its holder to purchase that number of the acquiring company's common stock having a market value of twice the rights' exercise price. The rights' current exercise price is $33.00. The exercise price and the number of shares issuable upon exercise are subject to adjustment from time to time to prevent dilution. The rights will expire on November 17, 2007, subject to Interpore Cross' right to extend such date, unless earlier redeemed or exchanged by Interpore Cross or terminated. Interpore Cross is entitled to redeem the rights at one cent per right at any time before they become exercisable. F-15 INTERPORE INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Treasury Stock In November 1998, Interpore Cross' Board of Directors approved a plan to repurchase up to 4.0 million shares of Interpore Cross common stock. Through December 31, 1998, Interpore Cross repurchased and placed into treasury 605,000 shares at a cost of approximately $3.1 million under this program. The repurchase approval terminated following the 605,000 share repurchase. Accounting for Stock-Based Compensation Interpore Cross applies Accounting Principles Board Opinion No. 25 (APB 25), Accounting for Stock Issued to Employees, and related interpretations in accounting for its employee stock options because, as discussed below, the alternative fair value accounting provided for under Statement of Financial Accounting Standards No. 123 (SFAS 123), Accounting for Stock-Based Compensation, requires use of option valuation models that were not developed for use in valuing employee stock options. Under APB 25, because the exercise price of Interpore Cross' employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized. Pro forma information regarding net income and earnings per share is required by SFAS 123, and has been determined as if Interpore Cross had accounted for employee stock options granted on or after January 1, 1995 under the fair value method of SFAS 123. The fair value for these options was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions: a risk-free interest rate of 6%, a volatility factor of the expected market price of Interpore Cross common stock of .75 in 1998 and .67 in 1999 and 2000, a weighted-average expected life of the options of six years, and no dividend yield. For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options' vesting periods. Interpore Cross' pro forma information, which reflects the charges related to options issued in 1998, 1999 and 2000 and may not be indicative of such charges in future periods, is as follows: Year Ended December 31, ---------------------------------------------------------- 1998 1999 2000 --------------- --------------- --------------- Pro forma net income (loss) (in thousands)................... $(3,138) $3,958 $3,054 Pro forma basic net income (loss) per share.................. $ (.23) $ .29 $ .22 Pro forma diluted net income (loss) per share................ $ (.23) $ .29 $ .20 7. Income Taxes Interpore Cross uses the liability method of accounting for income taxes as set forth in Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes. Under this method, deferred taxes are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Deferred tax assets are recognized and measured based on the likelihood of realization of the related tax benefit in the future. F-16 INTERPORE INTERNATIONAL, INC.

Interpore Cross also has research and development tax credit and alternative minimum tax credit carryforwards of approximately $325,000 for federal tax purposes and $33,000 for California tax purposes. The federal research and development tax credit carryforward will begin to expire in 2002. Prior to 1995, a valuation allowance was recorded to entirely offset the tax benefits of the federal carryforwards. In 1998 and 1999, the valuation allowance was reduced, and ultimately eliminated, to recognize the future tax benefits which management believes are more likely than not to be realized. The Tax Reform Act of 1986 includes provisions which significantly limit the potential use of net operating losses and tax credit carryforwards in situations where there is a change in ownership, as defined, of more than 50% during a cumulative three-year period. Accordingly, if a change in ownership occurs, the ultimate benefit realized from these carryforwards may be significantly reduced in total, and the amount that may be utilized in any given year may be significantly limited. California has enacted similar legislation. Interpore Cross has had stock issuances during the past three years and as a result of the merger with Cross, a greater than 50% change in ownership occurred during the year ended December 31, 1998. Accordingly, the use of these carryforwards will be limited to approximately $2.3 million per year. F-17 INTERPORE INTERNATIONAL, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) In addition to the net operating losses discussed above, Interpore Cross has federal net operating loss carryforwards at December 31, 2000 of approximately $4.6 million resulting from the acquisition of Interpore Orthopaedics, Inc. ("Orthopaedics"). As a result of the acquisition, Orthopaedics experienced a more than 50% ownership change. Accordingly, under the provisions of the 1986 Tax Reform Act, the use of Orthopaedics' net operating loss carryforwards is limited to approximately $300,000 per year. These carryforwards expire beginning in the year 2002. As a result of the annual limitation, it is estimated that a maximum of $1.3 million in net operating loss carryforwards will be available for use prior to expiration. The ultimate realization of the benefits of these loss carryforwards is dependent on future profitable operations of Orthopaedics. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The components of the net deferred tax asset consist of the following (in thousands): December 31, ----------------------------------- 1999 2000 -------------- ------------- Deferred tax assets: Interpore net operating loss carryforwards .......................... $2,097 $1,451 Orthopaedics net operating loss carryforwards ....................... 538 430 Research and development and alternative minimum tax credit carryforwards ........................................... 468 379 Reserves and accruals not currently deductible for tax purposes ..... 489 357 Inventory capitalization ............................................ 361 901 Depreciation not currently deductible for tax purposes .............. 130 168 --------- --------- Total deferred tax asset ............................................. $4,083 $3,686 ========= ======== 8. Commitments and Contingencies License Agreements Interpore Cross has agreements with its Synergy System Advisors under which it pays royalties ranging from 5% to 7% of net revenues generated from the sale of certain products within the Synergy Spinal System. Royalties are paid to the developers of the AGF technology at a rate of 5% of certain products within this product group. Litigation On September 5, 2000, our wholly-owned subsidiary, Cross, filed suit in the U.S. District Court, Central District of California, against Depuy AcroMed, Inc., a Johnson & Johnson company and Biedermann Motech GmbH, which alleges that Depuy Acromed has infringed and continues to infringe Cross' U.S. Patent Nos. 5,466,237 and 5,474,555. These patents relate to the VLS or Variable Locking Screw technology embodied in certain components of our Synergy Spinal System. The Complaint seeks damages for willful past and continuing infringement of the patents. The Complaint also seeks a declaratory judgment against Depuy Acromed and Biedermann Motech that Cross is not infringing Biedermann Motech's patent no. 5,207,678. Depuy AcroMed has responded to the Complaint denying all claims, alleging that Cross' patents are invalid and unenforceable, and alleging that it does not infringe. Aside from the patent litigation, the nature of our business subjects us to products liability and various other legal proceedings from time to time. We are currently involved in legal proceedings incidental to the normal conduct of our business. We do not believe that any liabilities relating to the legal proceedings to which we are a party are likely to be, individually or in the aggregate, material to our consolidated financial condition or results of operations.
