REGENERATION TECHNOLOGIES, INC.

We are a leader in the use of biologics and tissue-based innovations that are used to repair and promote the natural healing of human bone and other human tissues. Using core human physiology--the basic biology of natural tissues as they function in the body--our allografts are improving surgical outcomes. Our goal is to replace conventional implant approaches, including metals, synthetics and autograft implants, with allograft and for an allograft to become the implant of choice for tissue repair. In an allograft procedure, tissue is recovered from a cadaveric donor and is then transplanted into a patient's body to make the needed repair. An autograft procedure is one in which the surgeon harvests tissue from one part of a patient's body for transplant to another part of the body to make the needed repair.

We are a leading worldwide provider of comprehensive healing and biologic tissue products in a broad range of markets. In addition, we are the largest U.S. processor and distributor of precision tooled allografts both in terms of revenues and number of surgical procedures for the year ended December 31, 1999, with our allografts being distributed in all 50 states and in nine countries internationally. We also continue to be one of the leading processors of conventional allografts in the United States. We process human musculoskeletal and other tissues, including bone, cartilage, tendon, ligament, pericardial and cardiovascular tissue in producing our allografts. These tissues are then used to repair and promote the healing of a wide variety of bone and other tissue defects, including spinal vertebrae repair, musculoskeletal reconstruction, fracture repair, periodontal repair, urinary incontinence and heart valve disorders. Our current grafts range from conventional allografts to precision tooled grafting material, including bone dowels, wedges, pastes and pins, urological allografts and heart valves. During 1999, we shipped over 90,000 processed allografts used in an estimated 60,000 procedures. Often, more than one allograft is used in a given procedure.

The overall market in the United States for tissue repair and healing through the use of surgical implants, including metals, synthetics, and allografts, has grown considerably over the last several years, with revenues in the orthopedic and cardiovascular segments of this market exceeding an estimated $6.4 billion in 1999. In these segments, procedures using allografts, either conventional graft, bone paste, or specialty tooled tissues, totaled over 310,000 during 1999, accounting for revenues of over $410.0 million.

Processors of tissue supply allografts to hospitals and surgeons for use in surgery. The need for tissue is increasing each year and currently is being served by approximately 30 tissue banks in the United States that process and/or distribute bone or cardiovascular allografts. We have one of the most extensive tissue recovery programs in the United States, recovering bone or cardiovascular tissue from over 4,000 human donors during 1999, up from over 2,300 in 1998 and 1,500 in 1997. We believe our network of recovery groups accounted for approximately 34% of the human tissue recovered in the United States during 1999.

We pursue a market-by-market approach to distribution of our allografts, including strategic distribution arrangements in order to increase our penetration of selected markets. We have an alliance

1

with Medtronic Sofamor Danek in the spinal market, with Exactech, Inc. in portions of the non-spinal molded bone paste market, and with C.R. Bard, Inc. in the urological market.

Using our proprietary, patent-pending BioCleanse system, we believe we are the only tissue processor currently able to safely process tissue from multiple donors simultaneously. This system, which kills or inactivates all classes of conventional pathogens, viruses, microbes, bacteria and fungi, and which cleanses tissue both before and after processing, allows us to safely process tissue from up to 100 donors at the same time thereby significantly increasing the efficiency of tissue processing. In addition, our BioCleanse system is able to remove blood, fats, lipids and cellular debris from the tissue we process more successfully than traditional aseptic processing. We believe the removal of all blood, fat, lipids and cellular debris results in faster patient healing since it eliminates the need for the patient's body to remove these substances using natural processes following surgery. In contrast to traditional aseptic processing, our BioCleanse system also permits us to process tissue at lower average cost, and to process tissue safely and economically from donors and age groups that might not have been feasible without BioCleanse.

We plan to continue to develop new allografts and technologies within the orthopedics, urological and cardiovascular markets, and to develop additional tissue-related technologies for other markets. To accomplish this, we intend to continue to make use of our core technologies and processes which include precision machined cortical bone, osteoinductive allograft bone pastes, our proprietary BioCleanse system, segmentally demineralized bone allografts, osteoarticular grafts designed to fit specific surgical instruments, growth factors to stimulate bone or tissue growth, cortical allografts assembled from various smaller bone pieces, xenograft, or animal tissue, and bone treated to reduce materials that could cause immune responses.

RISK FACTORS

THIS OFFERING AND AN INVESTMENT IN OUR COMMON STOCK INVOLVE A HIGH DEGREE OF RISK. YOU SHOULD CONSIDER EACH OF THE RISKS AND UNCERTAINTIES DESCRIBED IN THIS
SECTION AND ALL OF THE OTHER INFORMATION IN THIS PROSPECTUS BEFORE DECIDING TO INVEST IN OUR COMMON STOCK. OUR BUSINESS, FINANCIAL CONDITION AND RESULTS OF OPERATIONS COULD BE SEVERELY HARMED BY ANY OF THE FOLLOWING RISKS. THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE IF ANY OF THESE RISKS OR UNCERTAINTIES DEVELOP INTO ACTUAL EVENTS. YOU MAY LOSE ALL OR PART OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK.

WE HAVE A LIMITED OPERATING HISTORY, ARE AT AN EARLY STAGE OF DEVELOPMENT

AND MAY NOT SUCCEED OR CONTINUE TO BE PROFITABLE.

We incorporated in 1997 and commenced operations as an independent entity in 1998, and are at an early stage of development. Accordingly, we have a limited operating history on which to base an evaluation of our business and prospects. We expect our operating expenses to increase and we will need to generate significant revenues to maintain profitability. We may not be able to achieve growth in our revenues at levels which will sustain or increase profitability on a quarterly or annual basis.

Many of the risks inherent in the development of a new enterprise will affect our business, including:

- market acceptance of our existing and future allografts;

- our ability to continue to develop markets for our technologies;

- our ability to raise sufficient capital to support the cost of commercializing our current allografts and technologies and developing new allografts and technologies to remain competitive; and

- our ability to attract and retain qualified management, sales, technical and scientific staff.

Our limited operating history and the uncertain nature of the markets in which we compete make it difficult for us to predict our future results of operations. As we increase our operating expenses to continue our research and development, expand manufacturing and add to our tissue recovery and distribution programs, these expenditures may not result in increased revenues and we may incur sizable losses.

WE DEPEND HEAVILY UPON A LIMITED NUMBER OF SOURCES OF HUMAN TISSUE, AND ANY FAILURE TO OBTAIN TISSUE FROM THESE SOURCES IN A TIMELY MANNER WILL INTERFERE WITH OUR ABILITY TO PROCESS AND DISTRIBUTE ALLOGRAFTS.

The University of Florida Tissue Bank, Inc., Tutogen Medical, Inc. and Allograft Resources of Wisconsin collectively supplied us with approximately 58% of the human tissue we obtained in the year ended December 31, 1999. The limited supply of human tissue has at times limited our growth, and may not be sufficient to meet our future needs. In addition, due to seasonal changes in mortality rates, some scarce tissues that we use for our allografts are at times in particularly short supply. We cannot be sure that our supply of tissue will continue to be available at current levels or will be sufficient to meet our needs. If we no longer are able to obtain tissue from these sources sufficient to meet our needs, we may not be able to locate replacement sources of tissue on commercially reasonable terms, if at all. Any interruption of our business caused by the need to locate additional sources of tissue could adversely affect our business and results of operations.

OUR SUCCESS WILL DEPEND ON THE CONTINUED ACCEPTANCE OF OUR ALLOGRAFTS AND

TECHNOLOGIES BY THE MEDICAL COMMUNITY.

Our new allografts, technologies or enhancements to existing allografts may never achieve broad market acceptance, which can be affected by numerous factors, including:

- clinical acceptance of our allografts and technologies;

4

- introduction of competitive tissue repair treatment options which render our allografts and technologies obsolete;

- lack of availability of third-party reimbursement; and

- our ability to train surgeons in the use of our allografts and technologies.

Market acceptance also will depend on our ability to demonstrate that our existing and new allografts and technologies are an attractive alternative to existing tissue repair treatment options. Our ability to do so will depend on surgeons' evaluations of the clinical safety, efficacy, ease of use, reliability and cost-effectiveness of these tissue repair options and technologies. For example, we believe that a small portion of the medical community has lingering concerns over the risk of disease transmission through the use of allografts. Furthermore, we believe that even if our allografts and technologies receive general acceptance within the medical community, recommendations and endorsements by influential surgeons will be important to the commercial success of our allografts and technologies.

IF WE FAIL TO ACHIEVE AND MAINTAIN THE HIGH PROCESSING AND MANUFACTURING STANDARDS THAT OUR ALLOGRAFTS REQUIRE OR IF WE ARE UNABLE TO DEVELOP ADDITIONAL MANUFACTURING CAPACITY, OUR COMMERCIAL OPPORTUNITY WILL BE REDUCED OR ELIMINATED.

Our allografts require careful calibration and precise, high-quality processing and manufacturing. Achieving precision and quality control requires skill and diligence by our personnel. If we fail to achieve and maintain these high processing and manufacturing standards, including the avoidance of the incidence of manufacturing errors, design defects or component failures, we could experience recalls or withdrawals of our allografts, delays or failures in allograft testing or delivery, cost overruns or other problems that would adversely affect our business. We can never completely eliminate the risk of errors, defects or failures. Further, to be successful, we will need to increase our manufacturing capacity, which we intend to do using a portion of the proceeds from this offering. We may experience difficulties in scaling-up manufacturing of our allografts, including problems related to yields, quality control and assurance, tissue availability, adequacy of control policies and procedures, and lack of skilled personnel. If we are unable to process and produce our allografts on a timely basis, at acceptable quality and costs, and in sufficient quantities, or if we experience unanticipated technological problems or delays in production, our business would be adversely affected.

RAPID TECHNOLOGICAL CHANGE WILL AFFECT US AND OUR CUSTOMERS, WHICH COULD

RESULT IN REDUCED DEMAND FOR OUR ALLOGRAFTS.

Our industry is characterized by rapidly changing technology and frequent introductions of new technologies. For example, steady improvements have been made in synthetic human tissue substitutes which compete with our allografts. Unlike allografts, synthetic tissue technologies are not dependent on the availability of human tissue. The successful introduction of synthetic technologies using recombinant technologies could result in a decline in demand for allografts. Although our growth strategy contemplates the introduction of new allografts and technologies, including the use of recombinant technologies, the development of these new allografts and technologies is a complex and uncertain process, requiring a high level of innovation, as well as the ability to accurately predict future technology and market trends. The allografts we currently have in development will require significant additional development, investment and testing. We may need to undertake costly and time-consuming efforts to achieve these objectives. We may not be able to respond effectively to technological changes and emerging industry standards, or to successfully identify, develop or support new technologies or enhancements to existing allografts in a timely and cost-effective manner, if at all. If we are unable to achieve the improvements in our allografts necessary for their successful commercialization, the demand for our allografts will suffer.

5

OUR INDUSTRY IS HIGHLY COMPETITIVE AND WE MAY NOT HAVE THE RESOURCES

REQUIRED TO COMPETE SUCCESSFULLY.

The medical technology/biotechnology industry is intensely competitive. We compete with companies in the United States and internationally that engage in the development and production of medical technologies and processes including:

- biotechnology, orthopedic, pharmaceutical, biomaterial, chemical and other companies;

- academic and scientific institutions; and

- public and private research organizations.

Allograft implants compete with autograft, metals and synthetic tissues, as well as with alternative medical procedures. For the foreseeable future, we believe a significant number of surgeons will continue to choose to perform autograft procedures when feasible, despite the necessity for performing a second operation. In addition, many members of the medical community will continue to prefer the use of metals and synthetics due in part to their familiarity with these products and the procedures required for their use.

Many of our competitors have much greater financial, technical, research, marketing, sales, distribution, service and other resources than we do. Moreover, our competitors may offer a broader array of tissue repair treatment products and technologies or may have greater name recognition than we do in the marketplace. Our competitors, including several development stage companies, may develop or market technologies that are more effective or commercially attractive than ours, or that may render our technologies obsolete. For example, the successful development of a synthetic tissue product that permits remodeling of bones could result in the eventual decline in the demand for allograft-based products and technologies.

WE ARE DEPENDENT UPON THE SUCCESS OF OUR STRATEGIC DISTRIBUTION

RELATIONSHIPS IN DISTRIBUTING OUR ALLOGRAFTS TO GENERATE OUR REVENUES.

While we market a portion of our current technologies directly to our customers, we currently derive the majority of our revenues through our relationships with a few distributors. In the year ended December 31, 1999, we derived approximately 52% of our net revenues through our management services distribution relationship with one company, Medtronic Sofamor Danek. This company provides nearly all of the instrumentation, surgeon training, distribution services and marketing materials for our line of spinal allografts. If our relationship with this distributor was terminated for any reason, it would materially and adversely affect our ability to generate revenues and profits.

We may need to obtain the assistance of additional distributors to market and distribute our new allografts and technologies, as well as to market and distribute our existing allografts and technologies to new market segments or geographical areas. We may not be able to find additional distributors who will agree to market and distribute our allografts and technologies on commercially reasonable terms, if at all. If we are unable to establish new distribution relationships or renew our current distribution arrangements on commercially acceptable terms, our operating results will suffer.

OUR ALLOGRAFTS COULD BECOME SUBJECT TO SIGNIFICANTLY GREATER REGULATION BY

THE FDA, WHICH COULD DISRUPT OUR BUSINESS.

The U.S. Food and Drug Administration has statutory authority to regulate allograft processing and allograft-based materials. Since 1997, the FDA has been working to establish a more comprehensive regulatory framework for human tissue-based allografts. The framework under FDA consideration would establish criteria for determining whether a particular human tissue-based product will be classified as human tissue, a medical device or biologic drug requiring premarket clearance or

6

approval. Our heart valve allografts currently are regulated as medical devices and we cannot be sure that the FDA will not seek to regulate our other allografts as medical devices or biologics in the future.

If the FDA decides to adopt and implement its proposed regulatory framework, one or more of our current allografts would then be regulated to a much greater extent. In addition to our heart valve allografts, one or more of our allografts in development may become subject to regulation as medical devices or biologic drugs. For allografts regulated as medical devices, we will need to obtain premarket clearance or approval through either the 510(k) premarket notification process, or the FDA's premarket approval process. Some of our proposed grafts also contain tissue derived from animals, commonly referred to as xenografts. Xenografts also are subject to premarket review by the FDA.

To obtain the necessary approvals or clearances, we would be required to submit premarket notifications, premarket approval applications and/or biologics license applications. The clinical testing and preparation of required applications would be time consuming and costly. In addition, we cannot be sure the FDA would approve our applications. The FDA could also require us to stop marketing our current allografts pending their approval or clearance. The FDA may require post-market testing and surveillance to monitor the effects of approved allografts, may restrict the commercial applications of our allografts, and may conduct periodic inspections of our facility and our suppliers' facilities. The FDA may withdraw our product approvals or clearances if we do not comply with its regulatory standards or if we encounter problems after the initial marketing. If we encounter delays during the FDA approval process, the period during which we have the exclusive right to commercialize any allografts for which we have received patent protection may be shortened.

From time to time, allegations may be made against us or against donor recovery groups or tissue banks, including those with which we have a relationship, about possible non-compliance with applicable FDA regulations or other relevant statutes and regulations. Allegations such as these could cause regulators or other authorities to take investigative or other action, or could cause negative publicity for us or our industry generally.

WE DEPEND ON PATENTS AND OTHER MEANS TO PROTECT OUR INTELLECTUAL PROPERTY,

WHICH MAY NOT ALWAYS BE ADEQUATE.

The law of patents and trade secrets is constantly evolving and often involves complex legal and factual questions. The coverage we seek in our patent applications can either be denied or significantly reduced before or after a patent is issued. Consequently, we cannot be sure that any particular patent we apply for will be issued, that the scope of the patent protection will exclude our competitors, that interference proceedings regarding any of our patent applications will not be filed, or that a patent will provide any other competitive advantage to us. In addition, we cannot be sure that any of our patents will be held valid if challenged or that others will not claim rights in or ownership of the patents and other proprietary rights held by us.

Because patent applications are secret until patents are actually issued and the publication of discoveries in the scientific or patent literature lags behind actual discoveries, we cannot be certain if our patent application was the first application filed covering a particular invention. If another party's rights to an invention are superior to ours, we may not be able to obtain a license to use that party's invention on commercially reasonable terms, if at all. In addition, our competitors, many of which have greater resources than we do, could seek to apply for and obtain patents that will prevent, limit or interfere with our ability to make use of our inventions either in the United States or in international markets. Further, the laws of some foreign countries do not always protect our intellectual property rights to the same extent as do the laws of the United States. Litigation or regulatory proceedings in the United States or foreign countries also may be necessary to enforce our patent or other intellectual property rights or to determine the scope and validity of our competitors' proprietary rights. These proceedings can be costly, result in product development delays, and divert our management's attention from our business.

7

We also rely upon unpatented proprietary technology, and we cannot assure you that others will not independently develop substantially equivalent technology or otherwise gain access to or disclose our proprietary technology. We may not be able to meaningfully protect our rights in this proprietary technology, which would reduce our ability to compete in the market.

In 1996, a law was passed in the United States that limits the enforcement of patents covering the performance of surgical or medical procedures on a human body. This law prevents medical practitioners and health care entities who practice these procedures from being sued for patent infringement. Therefore, depending upon how these limitations are interpreted by the courts, they could have a material adverse effect on our ability to enforce any of our proprietary methods or procedures deemed to be surgical or medical procedures.

ALTHOUGH WE HAVE CONFIDENTIALITY AGREEMENTS WITH OUR EMPLOYEES AND OTHERS, THESE AGREEMENTS MAY NOT ADEQUATELY PREVENT DISCLOSURE OF TRADE SECRETS AND OTHER PROPRIETARY INFORMATION.

Our policy is to execute confidentiality agreements with our employees and consultants upon the commencement of their employment or consulting arrangement with us. These agreements generally require that all confidential information developed by an individual or to which the individual is exposed during the course of his or her relationship with us must be kept confidential even after the individual has left our employment. These agreements also generally provide that inventions conceived by the individual in the course of rendering services to us shall be our exclusive property. We cannot be sure that these agreements will provide meaningful protection of our proprietary and other confidential information. In addition, in some situations, these agreements may conflict with, or be subject to, the rights of third parties with whom our employees or consultants have prior employment or consulting relationships. We may be forced to engage in costly and time-consuming litigation to determine the scope of and to enforce our proprietary rights. Even if successful, any litigation could divert our management's attention from our business.

OUR SUCCESS WILL DEPEND IN PART ON OUR ABILITY TO OPERATE WITHOUT INFRINGING

ON OR MISAPPROPRIATING THE PROPRIETARY RIGHTS OF OTHERS.

We cannot be certain that U.S. or foreign patents or patent applications of other companies do not exist or will not be issued that would materially and adversely affect our ability to commercialize our grafts. We may be sued for infringing or misappropriating the patent or other intellectual property rights of others. Intellectual property litigation is costly and, even if we prevail, the cost of this litigation could negatively affect our business. If we do not prevail in litigation, in addition to any damages we might have to pay, we could be required to stop the infringing activity or obtain a license requiring us to make royalty payments. Any license we are required to obtain may not be available to us on commercially acceptable terms, if at all. In addition, any license we are required to obtain may be non-exclusive, and therefore our competitors may have access to the same technology licensed to us. If we fail to obtain a required license or are unable to design around another company's patent, we may be unable to make use of some of our technologies or distribute our grafts.

WE DEPEND ON THE CONTINUED SERVICE OF A NUMBER OF OUR KEY EMPLOYEES, AND WE

FACE INTENSE COMPETITION FOR PERSONNEL.

We are highly dependent on the members of our management and scientific staff, the loss of one or more of whom could have a material adverse effect on us. In particular, we believe our success to be particularly dependent upon the services of our Chief Executive Officer, James M. Grooms. In addition, we believe that our future success will depend in large part upon our ability to attract and retain highly skilled, scientific, managerial and manufacturing personnel. We face significant competition for personnel from other companies, research and academic institutions, government entities and other organizations. We may not be successful in hiring or retaining the personnel we need and this could adversely affect our business.

8

WE MAY BE EXPOSED TO PRODUCT LIABILITY CLAIMS WHICH COULD NEGATIVELY IMPACT

OUR BUSINESS.

Our business entails an inherent risk of product liability claims, and substantial product liability claims may be asserted against us. Although we have not received any material product liability claims to date and have a $20.0 million insurance policy to cover these claims should they arise, claims could arise in the future for which our insurance will not be adequate. Moreover, insurance covering our business may not always be available in the future on commercially reasonable terms, if at all. In addition, successful product liability claims made against one of our competitors could cause claims to be made against us or expose us to a perception that we are vulnerable to similar claims. Any product liability claim, if successful, could have a detrimental effect on our financial condition. In addition, claims against us, regardless of their merit or potential outcome, may also hurt our ability to obtain surgeon endorsement of our allografts or to expand our business.

NEGATIVE PUBLICITY CONCERNING METHODS OF TISSUE RECOVERY AND SCREENING OF DONOR TISSUE IN OUR INDUSTRY COULD REDUCE DEMAND FOR OUR ALLOGRAFTS AND IMPACT THE SUPPLY OF AVAILABLE DONOR TISSUE.

Widespread market acceptance of our allografts may be limited by media reports or other negative publicity concerning both improper methods of tissue recovery from donors and the risk of disease transmission from donated tissue. Unfavorable reports of illegal tissue recovery practices, both in the United States and internationally, as well as incidents of improperly processed tissue leading to transmission of disease, may broadly affect the rate of future tissue donation and market acceptance of allograft technologies. Potential patients may not distinguish between our allografts, technologies and the tissue recovery and processing procedures we have in place, versus those of our competitors or others engaged in tissue recovery. In addition, families of potential donors may become reluctant to agree to donate tissue to "for profit" tissue processors. Any adverse consequences resulting from tissue recovery or processing practices could adversely affect patient acceptance of allografts as a tissue repair treatment option, which could materially and adversely affect our business.

WE MAY NEED TO RAISE ADDITIONAL FUNDS TO OPERATE AND GROW OUR BUSINESS, AND IF WE ARE UNABLE TO RAISE THESE FUNDS, OUR ABILITY TO EFFECT OUR GROWTH STRATEGY COULD BE DISRUPTED.

We may need additional funds to operate our business and to pursue our growth strategy. The extent of our future capital requirements and the adequacy of available funds will depend on numerous factors, including:

- market acceptance of our existing and future allografts and tissue-based technologies;

- progress in our efforts to develop new allografts and tissue-based technologies;

- our success in commercializing technologies we have in development; and

- the development of strategic distribution alliances.

We may be required to obtain additional funds through equity or debt financings, strategic alliances or other sources. The terms of any future equity financings may be dilutive to our stockholders and the terms of any debt financings likely will contain restrictive covenants that limit our ability to pursue particular courses of action, including paying dividends. Our ability to obtain financing is dependent upon the status of our future business prospects, as well as conditions prevailing in the capital markets. Additional sources of financing may not be available to us on commercially reasonable terms, if at all.

WE MAY NOT BE SUCCESSFUL IN EXPANDING OUR DISTRIBUTION ACTIVITIES INTO

INTERNATIONAL MARKETS.

We are seeking to expand our operations outside the United States. To date we have limited experience operating internationally. In the year ended December 31, 1999, international sales

9

comprised approximately 2.6% of our net revenues. Our international operations will be subject to a number of risks which may vary from the risks we face in the United States, including:

- the need to obtain regulatory approvals in foreign countries before we can offer our grafts and technologies for use;

- longer distribution-to-collection cycles, as well as difficulty in collecting amounts owed to us;

- dependence on local distributors;

- limited protection of intellectual property rights;

- fluctuations in the values of foreign currencies; and

- political and economic instability.

If we are unable to effectively expand our operations in international markets, our business strategy would be negatively impacted.

ANY ACQUISITIONS WE MAKE WILL CAUSE US TO INCUR A VARIETY OF COSTS AND MAY

POTENTIALLY EXPOSE US TO ADDITIONAL RISKS.

We may consider acquiring other businesses or technologies that we believe are a strategic fit with our business. If we do make acquisitions, we could:

- issue equity securities which could be dilutive to our stockholders;

- incur substantial debt; or

- assume contingent liabilities or liabilities of which we may be unaware at the time we make the acquisition or which may be larger than we believed.

In addition, we may have difficulty integrating the personnel, operations or technologies we acquire, which could disrupt our business, distract our management and employees, and increase our operating expenses. Future acquisitions also might negatively impact our strategic distribution alliances.

OUR INDUSTRY IS SUBJECT TO GOVERNMENT REGULATIONS WHICH CAN SIGNIFICANTLY

IMPACT OUR BUSINESS.

Some aspects of our business are subject to local, state, federal or international regulation. Changes in the laws or new interpretations of existing laws could negatively affect our business, revenues or prospects, and increase the costs associated with conducting our business. In particular, the procurement and transplantation of allograft tissue is subject to federal regulation under the National Organ Transplant Act, or NOTA, a criminal statute that prohibits the purchase and sale of human organs, including bone and other tissue. NOTA permits the payment of reasonable expenses associated with the transportation, processing, preservation, quality control and storage of human tissue, which are the types of services we perform. If in the future NOTA were amended or interpreted in a way that makes us unable to include some of these costs in the amounts we charge our customers, it could adversely affect our business. It is possible that more restrictive interpretations or expansions of NOTA could be adopted in the future which could require us to change one or more aspects of our method of operations, at a substantial cost, in order to continue to comply with this statute.

We also are subject to a variety of local, state and federal government laws and regulations relating to the storage, handling, generation, manufacture and disposal of medical wastes from the production of our allografts. If we fail to conduct our business in compliance with these laws and regulations, it could subject us to significant liabilities, which could have a negative impact on our financial results.

10

IF THIRD PARTY PAYORS FAIL TO PROVIDE APPROPRIATE LEVELS OF REIMBURSEMENT

FOR THE USE OF OUR ALLOGRAFTS, OUR REVENUES WOULD BE ADVERSELY AFFECTED.

Our revenues depend largely on the reimbursement of patients' medical expenses by government health care programs and private health insurers. Governments and private insurers closely examine medical procedures incorporating new technologies to determine whether the procedures will be covered by payment, and if so, the level of payment which may apply. We cannot be sure that third party payors will continue to reimburse us or provide payment at levels which will be profitable to us.

CHANGES TO THE EXISTING HEALTHCARE INDUSTRY COULD LOWER THE AMOUNT WE ARE

PAID FOR OUR SERVICES, DECREASING OUR REVENUES.

Political, economic and regulatory influences are subjecting the healthcare industry in the United States to fundamental change. Any new federal or state legislation could result in significant changes in the availability, delivery, pricing and payment for healthcare services and products. It is not possible to predict whether any significant new healthcare legislation will have a negative impact on our business. Any significant healthcare legislation, if adopted, could have a material adverse effect on our business, financial condition and results of operations.

OUR STOCK PRICE MAY DECLINE AFTER THIS OFFERING AND MAY BE VOLATILE IN THE

FUTURE.

The market for shares in newly public technology companies, particularly medical device or biotechnology-related companies, is subject to extreme price and volume fluctuations. These broad fluctuations may materially and adversely affect the market price of our common stock. You may not be able to resell any shares you buy from us at or above the initial public offering price due to a number of factors, including:

- actual or anticipated fluctuations in our operating results;

- changes in investors' and securities analysts' expectations as to our future financial performance or changes in financial estimates of securities analysts;

- announcement of new allografts or product enhancements by us or our competitors;

- technological innovations by us or our competitors;

- negative publicity concerning methods of tissue recovery and screening; and

- the operating and stock price performance of comparable companies.

In addition, although our common stock will be quoted on the Nasdaq National Market, an active trading market may not develop or sustain itself after this offering.

OWNERSHIP OF OUR STOCK IS HEAVILY CONCENTRATED AND THESE STOCKHOLDERS WILL

CONTROL ALL MATTERS REQUIRING STOCKHOLDER APPROVAL.

After giving effect to this offering and assuming the full exercise of the underwriters' over-allotment option, our directors, executive officers, and stockholders holding greater than 5% of our common stock beneficially owned approximately % of our outstanding common stock. As a result, these stockholders are able to control all matters requiring stockholder approval, including the election of directors and approval of significant transactions. This concentration of ownership may also have the effect of delaying or preventing a change in control of our company.

11

PROVISIONS OF OUR GOVERNING DOCUMENTS AND DELAWARE LAW COULD DISCOURAGE

ACQUISITION PROPOSALS OR DELAY A CHANGE IN OUR CONTROL.

Our certificate of incorporation and by-laws contain anti-takeover provisions, including those listed below, that could make it more difficult for a third party to acquire control of us, even if that change in control would be beneficial to stockholders:

- our board of directors has the authority to issue common stock and preferred stock and to determine the price, rights and preferences of any new series of preferred stock without stockholder approval;

- our board of directors is divided into three classes, with each class serving staggered three-year terms;

- supermajority voting is required to amend key provisions of our certificate of incorporation and by-laws;

- there are limitations on who can call special meetings of stockholders;

- stockholders may not take action by written consent; and

- advance notice is required for nominations of directors and for stockholder proposals to be voted upon at stockholder meetings.

In addition, provisions of Delaware law and our stock option plans may also discourage, delay or prevent a change of control of our company or unsolicited acquisition proposals.

OUR MANAGEMENT WILL HAVE BROAD DISCRETION AS TO THE USE OF PROCEEDS OF THIS

OFFERING.

Our management will have broad discretion as to how to use the net proceeds of this offering. You will be relying on the judgment of our management regarding the application of the proceeds of this offering. The results and effectiveness of the use of the proceeds are uncertain.

YOU WILL INCUR IMMEDIATE DILUTION IN THIS OFFERING.

The initial public offering price of our common stock will be substantially higher than the pro forma net tangible book value per share of our outstanding shares of common stock immediately after this offering. Therefore, if you purchase our common stock in this offering at the initial public offering price of $ per share, you will incur immediate dilution of $ in the net tangible book value per share from the price you pay for the shares you purchase.

FUTURE SALES OF OUR COMMON STOCK COULD ADVERSELY AFFECT THE MARKET PRICE OF

OUR COMMON STOCK.

Sales of our common stock in the public market following this offering could adversely affect the market price of our common stock. Of the shares that will be outstanding upon the closing of this offering:

- all of the shares offered under this prospectus will be freely tradable in the public market;

- approximately additional shares may be sold after the expiration of the 180-day lock-up agreements entered into by our officers, directors and existing stockholders; and

- approximately additional shares may be sold upon the exercise of stock options and warrants after the expiration of the 180-day lock-up period.

12

USE OF PROCEEDS

We estimate the net proceeds to us from the sale of the shares of common stock we are offering, after deducting underwriting discounts and commissions and the estimated offering expenses payable by us, will be approximately $ million, assuming an initial public offering price of $ per share. We will not receive any proceeds from the sale of shares by the selling stockholder. See "Underwriting."

We intend to use the net proceeds of this offering for continued research and development, to construct and equip a new manufacturing facility, to construct additional BioCleanse systems and other automated processing systems, to expand our tissue recovery and distribution activities, and for general corporate purposes, including working capital.

In addition, we may also use a portion of the net proceeds from this offering to acquire businesses, assets, technologies or product lines that complement our existing business if we could make these acquisitions on terms which we deem to be favorable. Other than our acquisition of the tissue processing and distribution business of Alabama Tissue Center immediately prior to the closing of this offering, we do not have any commitments to make any acquisition and have not allocated a specific amount of the net proceeds for this purpose.

Our management will have significant flexibility in applying the net proceeds of the offering. Pending any use as described above, we intend to invest unused proceeds in short-term, interest-bearing investment-grade instruments.

DIVIDEND POLICY

We have never declared nor paid any cash dividends on our capital stock. In addition, our current credit facility restricts our ability to pay any dividends and any future facility may contain similar restrictions. We currently anticipate that we will retain any future earnings for the development and operation of our business. Accordingly, we do not anticipate paying cash dividends on our capital stock in the foreseeable future.

CAPITALIZATION
(IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

The following table sets forth our capitalization as of December 31, 1999:
(1) on an actual basis; and (2) on an as adjusted basis to reflect the conversion of our outstanding preferred stock into common stock and the sale of the shares of common stock to be sold by us (assuming an initial public offering price of $ per share) after deducting underwriting discounts and commissions and other estimated offering expenses and the application of the estimated net proceeds. This table should be read along with "Management's Discussion and Analysis of Financial Condition and Results of Operations" and our consolidated financial statements and accompanying notes included elsewhere in this prospectus.

DILUTION

Our pro forma net tangible book value as of December 31, 1999 was approximately $ , or $ per share of common stock, after giving effect to the conversion of all outstanding shares of preferred stock. Pro forma net tangible book value per share is equal to the amount of our tangible net assets, less total liabilities, divided by the pro forma number of shares of our common stock outstanding as of December 31, 1999. After giving effect to the sale by us of the shares of common stock offered hereby, assuming an initial public offering price of $ per share, and the application of the net proceeds from this offering, our pro forma net tangible adjusted book value at December 31, 1999 would have been approximately $ , or $ per share of our common stock. This amount represents an immediate increase in our pro forma net tangible book value of $ per share to existing stockholders and an immediate dilution in net tangible book value of $ per share to new investors in the offering.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

We are a leader in the use of biologics and tissue-based innovations that repair and promote the natural healing of human bone and other human tissues. We are the largest U.S. processor and distributor of precision tooled allografts both in terms of revenues and surgical procedures for the year ended December 31, 1999. These allograft implants are used in surgical reconstruction, bone healing and tissue repair, and are made from bone, cartilage, tendon, ligament and other soft tissues recovered from cadaveric tissue donors primarily through a national network of organ and tissue recovery agencies.

We were incorporated in 1997 as a wholly owned subsidiary of the University of Florida Tissue Bank, Inc., or UFTB. We began operations on February 12, 1998 when UFTB contributed to us its allograft manufacturing and processing operations, related equipment and technologies, distribution arrangements, research and development activities and certain other assets in exchange for shares of preferred stock. We also assumed various liabilities of UFTB that were related to the transferred business. At approximately the same time, we sold shares of preferred stock to a number of unrelated investors.

In addition, UFTB assigned to us various agreements to which it was party at the time of the separation, including an agreement with Medtronic Sofamor Danek under which that company was given the right to be the exclusive provider of management services for our current line of allografts for use in spinal and cranial medical procedures, including our bone dowels. Under this agreement, we are required to pay Medtronic Sofamor Danek 70% of the amount charged for our spinal allografts.

At approximately the time of our separation from UFTB, James M. Grooms, our President and Chief Executive Officer and former officer of UFTB prior to our separation from that entity, contributed his royalty rights in certain intellectual property to us in exchange for shares of our preferred stock. We recorded the assets acquired from UFTB and Mr. Grooms and the liabilities assumed from UFTB at their historical cost basis since these were deemed to be transactions between entities under common control.

On April 15, 1999, we entered into a Programs Transfer Agreement with UFTB under which UFTB transferred to us its tissue recovery operations outside of Florida and Georgia, conventional allograft distribution services, allograft inventory, certain equipment and fixtures and its interest in agreements with various tissue recovery programs in exchange for the offset of amounts owed to us by UFTB. On April 15, 1999, we also entered into a Tissue Recovery Agreement with UFTB under which UFTB functions as one of our tissue recovery agencies, supplying to us the majority of the tissue it recovers.

On November 1, 1999, we acquired the net assets of Georgia Tissue Bank, Inc. along with certain equipment owned by a director of Georgia Tissue Bank. We financed this acquisition with a cash payment of $0.5 million and promissory notes totaling $1.3 million. We recorded our acquisition of the net assets of Georgia Tissue Bank under the purchase method of accounting.

On April 27, 2000, we entered into an agreement to acquire the tissue processing and distribution business of Alabama Tissue Center. Under that agreement, we are obligated to pay the seller $3.5 million in shares of our common stock, valued at a price equal to the initial public offering price, and $0.3 million in cash, with the possible payment of an additional $0.3 million in cash if specified milestones are achieved by the acquired business following the acquisition. If our initial public offering is not consummated, we are not obligated to consummate the acquisition.

All of our operations are located in the United States, although we distribute our allografts to customers both within and outside the United States. In 1999, 97.4% of our net revenues were from

17

domestic tissue distribution compared to 100% of our net revenues in 1998. We expect the portion of our net revenues attributable to international operations will increase in the future.

In general, tissue recovery rates increase during the month of March and decrease during the month of August. Although this seasonality in tissue recovery affects the availability of donor tissue during these periods, it historically has not affected our ability to continue processing available donor tissue or supply needed allografts. We attempt to manage our business so that these short-term reductions in donor tissue recoveries do not affect the quarterly results of our business.

RESULTS OF OPERATIONS

The following table sets forth, in both dollars and as a percentage of net revenues, the results of our operations for the periods indicated:

YEAR ENDED DECEMBER 31, 1999 COMPARED TO PERIOD ENDED DECEMBER 31, 1998

AMOUNTS STATED BELOW FOR THE PERIOD ENDED DECEMBER 31, 1998 INCLUDE ONLY APPROXIMATELY TEN AND ONE-HALF MONTHS OF OPERATIONS, COMPARED TO A FULL 12 MONTHS FOR THE YEAR ENDED DECEMBER 31, 1999.

TOTAL REVENUES. Our total revenues increased by $37.7 million, or 106.8%, to $73.0 million for the year ended December 31, 1999 from $35.3 million for the period ended December 31, 1998.

Fees from tissue distribution increased by $38.9 million, or 121.9%, to $70.8 million for the year ended December 31, 1999 from $31.9 million for the period ended December 31, 1998. The increase in fees from tissue distribution was due largely to an increase of $26.7 million in revenues from the distribution of our spinal allografts, an increase of $8.0 million from the distribution of conventional tissue and an increase of $4.2 million from the distribution of other precision tooled allografts. The increase in our revenues from spinal allografts was due primarily to our introduction of three new spinal allografts in late 1998. Conventional tissue revenues increased due to our assumption of UFTB's conventional tissue distribution business in April 1999. Of the increase in our revenues from precision tooled allografts, $3.6 million was related to the introduction of five new allografts in 1998, and $0.6 million was related to the introduction of four new allografts in 1999.

Other revenues from core operations, which consist of tissue processing fees, biomedical laboratory fees and manufacturing royalties, decreased by $1.2 million, or 33.5%, to $2.2 million for the year ended December 31, 1999 from $3.4 million for the period ended December 31, 1998. This decrease was due largely to a reduction during 1999 of processing fees from UFTB as a result of our assumption of their conventional tissue distribution business in April 1999 rather than continuing to process its conventional tissue for a fee.

MANAGEMENT SERVICES FEES. Management services fees, which consist of amounts paid to Medtronic Sofamor Danek for distribution of our allografts for which they provide management services, increased by $15.9 million, or 66.0%, to $40.0 million for the year ended December 31, 1999 from $24.1 million for the period ended December 31, 1998. The increase in the absolute amount of these fees was due to the greater revenues generated through the management services of Medtronic Sofamor Danek. As a percentage of total revenues, however, these fees decreased from 68.4% for the period ended December 31, 1998 to 54.8% for the year ended December 31, 1999. This decrease in management fees as a percentage of total revenues was attributable to a decrease in the management services fee payable by us on certain of our allografts from 80% to 70% during the first quarter of 1999. In addition, an increase in distribution of our non-spinal allografts, for which we do not pay a management services fee, contributed to the reduction in management services fees as a percentage of total fees.

NET REVENUES. Our net revenues increased by $21.9 million, or 197.3%, to $33.0 million for the year ended December 31, 1999 from $11.1 million for the period ended December 31, 1998. As a percentage of total revenues, our net revenues increased from 31.6% for the period ended December 31, 1998 to 45.2% for the year ended December 31, 1999. This increase was due mainly to the impact of distribution of our non-spinal allografts, for which we do not pay management services fees.

COSTS OF PROCESSING AND DISTRIBUTION. Costs of processing and distribution increased by $9.4 million, or 95.9%, to $19.2 million for the year ended December 31, 1999 from $9.8 million for the period ended December 31, 1998. As a percentage of net revenues, however, these costs decreased from 88.5% for the period ended December 31, 1998 to 58.0% for the year ended December 31, 1999. This reduction was attributable primarily to improvements in processing efficiencies achieved through our introduction of automated processing machinery, as well as efficiencies associated with increased volume. In addition, the increase in our net revenues due to reduced management services fees payable by us, also resulted in a reduction of the percentage of our net revenues attributable to costs of processing and distribution.

MARKETING, GENERAL AND ADMINISTRATIVE EXPENSES. Marketing, general and administrative expenses increased by $5.7 million, or 142.3%, to $9.7 million for the year ended December 31, 1999 from $4.0 million for the period ended December 31, 1998. Contributing to this increase was an increase of $1.1 million in marketing and direct distribution payroll expense, as well as an increase of $0.7 million in administrative expenses to support the growth of our business. Also contributing to the increase was a $0.7 million increase in facilities expense during 1999 as we went from leasing one building at the beginning of 1998 to two buildings in the last quarter of 1998. Other cost increases included an increase in distributor commissions, primarily on conventional tissue, of $1.2 million, increased depreciation expense of $0.4 million, increased royalties on conventional tissue of $0.3 million and increased professional fees and travel related expenses of $0.9 million to support our distribution and marketing efforts. As a percentage of net revenues, marketing, general and administrative expenses decreased from 35.8% for the period ended December 31, 1998 to 29.5% for the year ended December 31, 1999. This decrease was due to our net revenues rising without a commensurate increase in marketing, general and administrative expenses.

RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses increased by $0.2 million, or 13.3%, to $1.7 million for the year ended December 31, 1999 from $1.5 million for the period ended December 31, 1998. This increase was due largely to the hiring of additional personnel to develop new allografts and technologies. All research and development costs are expensed as incurred. As a percentage of net revenues, research and development expenses decreased from 13.2% for the period ended December 31, 1998 to 5.1% for the year ended December 31, 1999. This decrease was due to our net revenues rising without a commensurate increase in research and development expenses.

INTEREST INCOME AND EXPENSE--NET. Net interest expense for the year ended December 31, 1999 was $98,000 compared to net interest income of $34,000 for the period ended December 31, 1998. The increase in the amount of interest we paid was due largely to borrowings under our line of credit facility entered into during 1999, as well as interest paid on a number of capital leases entered into during 1999.

INCOME TAX BENEFIT. In 1998 we recorded a valuation allowance with respect to a deferred tax asset since we believed at the time that it was unlikely to be realized. In 1999, as a result of achieving positive net income for that year, this valuation allowance was reversed resulting in an income tax benefit of $0.6 million for 1999.

QUARTERLY RESULTS OF OPERATIONS (UNAUDITED)

The following tables present unaudited quarterly statement of operations data in both dollars and as percentages of net revenues for each of the quarters for the fiscal periods ended December 31, 1998 and 1999. This information is unaudited, but in our opinion has been prepared substantially on the same basis as the audited consolidated financial statements which appear elsewhere in this prospectus. All necessary adjustments, consisting only of normal recurring adjustments, have been included in the amounts to present fairly the unaudited quarterly results. You should read the quarterly data presented below in conjunction with our consolidated financial statements and the accompanying notes appearing elsewhere in this prospectus. You should not view the results of operations for any quarter as an indication of the results of operations for any future period.

Our quarterly operating results have fluctuated significantly since we began operations. One of the primary reasons for these fluctuations is our historical and current dependence upon our MD-Series Threaded Bone Dowels. In an effort to smooth these fluctuations, we have attempted to diversify the allografts we offer, including the introduction of eight new allografts during 1998. While these new allografts accounted for only $2.9 million of total revenues during 1998, they accounted for $31.3 million of the $37.7 million increase in our 1999 total revenues. Also accounting for a portion of the increase in our total revenues for 1999 was an increase of $8.0 million in conventional tissue revenues when we assumed UFTB's conventional tissue processing business in April 1999.

Our revenue diversification efforts also favorably impacted our gross profit as a percentage of net revenues, which increased from 11.5% of our net revenues in 1998 to 41.9% in 1999. Adding to this impact was a decrease in the first quarter of 1999 in the management services fees we are required to pay to Medtronic Sofamor Danek for certain of our spinal allografts from 80% to 70%. The impact of this decrease was an effective increase in the net revenues from each allograft distributed through that company without any change in direct costs. Also increasing our 1999 gross margin was an increase in distribution of our bone paste allografts for the spinal market, which bear lower management services fees.

In order to permit the expansion of our business and increase revenues, we incurred additional manufacturing costs and material usage in the fourth quarter 1998. The result of these activities was a negative gross margin of $0.2 million or 6.5% of net revenues during the fourth quarter of 1998. These additional costs included higher payroll costs of approximately $0.2 million due to the hiring of additional personnel and approximately $0.3 million for additional lab testing, packaging and tools and equipment. We also incurred higher material costs of $0.4 million due to higher material usage during the early phases of production.

In addition to the higher manufacturing costs incurred in the fourth quarter of 1998, we also hired additional marketing, distribution and administrative staff in the second through fourth quarters of 1998 to support the anticipated growth in our business. These staff increases and related costs contributed to our operating losses in the second through fourth quarters of 1998 and the first quarter of 1999.

LIQUIDITY AND CAPITAL RESOURCES

Since we began operations, we have financed our operations primarily through our sale of preferred stock, totaling $6.4 million in net proceeds in 1998 and $10.0 million in net proceeds in 1999.

Our net cash used in operating activities increased by $9.9 million to $6.5 million for the year ended December 31, 1999 from net cash provided by operating activities of $3.4 million for the period ended December 31, 1998. This increase was largely due to the payment of a $4.5 million non-refundable fee by Medtronic Sofamor Danek during 1998 related to our agreement with that company and an increase in our working capital of approximately $5.5 million for the year ended December 31, 1999. For accounting purposes, we deferred the $4.5 million fee we received from Medtronic Sofamor Danek and we are recognizing it on a straight-line basis over the 20 year life of the agreement.

Our net cash used in investing activities increased by $1.0 million to $2.9 million for the year ended December 31, 1999 from $1.9 million for the period ended December 31, 1998. This increase was due primarily to the $0.5 million we paid for our acquisition of the net assets of Georgia Tissue Bank, plus an increase of $0.5 million in the amount paid for the purchase of property, plant and equipment during 1999. During the year ended December 31, 1999, $0.8 million of cash was used in the purchase of property, plant and equipment largely related to our BioCleanse processing facility.

Net cash provided by financing activities increased by $10.6 million to $13.0 million for the year ended December 31, 1999 from $2.4 million for the period ended December 31, 1998. This increase

22

was due primarily to the $10.0 million in net proceeds we realized from our sale of preferred stock during 1999, $2.8 million in net borrowings under our line of credit facility, and $0.7 million in proceeds due from a stockholder. In 1998, we received $6.6 million of proceeds from our sale of preferred stock and financed $3.8 million in receivables from UFTB. Our line of credit facility permits us to borrow up to $6.0 million on a revolving basis and is collateralized by our accounts receivable. This line of credit facility expires in September 2000. As of December 31, 1999, we had excess borrowing capacity of approximately $3.2 million under this facility.

On March 30, 2000, we purchased the buildings and land that we currently occupy, plus an additional 20.8 acres of land for future expansion. The purchase price for the two buildings and 6.2 acres on which they are situated was $3.6 million, with the additional parcel of land costing approximately $0.6 million. In order to finance the purchase, we entered into a 20-year term loan in the amount of $2.8 million, collateralized by the property. The remainder of the purchase price was financed with a portion of the proceeds from our sale of preferred stock during 1999. We continue to lease approximately 18,000 square feet of space in buildings adjacent to those we purchased and 8,800 square feet of warehouse space.

We currently believe that the net proceeds from this offering, cash from operations and our existing cash and cash equivalents will be sufficient to meet our anticipated cash requirements for at least the next 12 months. The completion of one or more acquisitions by us could affect our need for capital.

IMPACT OF INFLATION

Inflation generally affects us by increasing our cost of labor, equipment and processing tools and supplies. We do not believe that the relatively low rates of inflation experienced in the United States since the time we began operations has had any material effect on our business.

INTEREST RATE RISK

We are subject to market risk from exposure to changes in interest rates based upon our financing, investing and cash management activities. We use a balanced mix of debt maturities along with both fixed-rate and variable-rate debt to manage its exposure to changes in interest rates. We do not expect changes in interest rates to have a material adverse effect on our income or our cash flows in 2000. However, we cannot assure you that interest rates will not significantly change in 2000.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

The Financial Accounting Standards Board recently issued Statement of Financial Accounting Standards No. 137, ACCOUNTING FOR DERIVATIVE INSTRUMENTS
AND HEDGING ACTIVITIES--DEFERRAL OF EFFECTIVE DATE OF FASB STATEMENT NO. 133. SFAS No. 137 defers for one year the effective date of SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. The rule now will apply to all fiscal quarters of all fiscal years beginning after June 15, 2000. SFAS No. 137 permits early adoption as of the beginning of any fiscal quarter after its issuance. SFAS No. 133 will require us to recognize all derivatives on our balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives will either be offset against the change in fair value of the hedged assets, liabilities, of firm commitments through earnings or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. We have not completed our evaluation of the impact of SFAS No. 133, if any, on our consolidated financial statements.

BUSINESS

INDUSTRY OVERVIEW

Defects in bone and other human tissue can be caused by a variety of sources including trauma, congenital defect, infectious disease, cancer and other disease conditions. The prevalent method used by surgeons to repair and promote the healing of defective tissue is surgery, principally through the use of surgical implants. When considering a surgical procedure for tissue repair, surgeons and patients face a number of treatment options including metals and synthetics, "autograft" tissue, "allograft" tissue and "xenograft" tissue. An autograft procedure is one in which the surgeon harvests tissue from one part of a patient's body for transplant to another part of the body to make the needed repair. In an allograft procedure, tissue is recovered from a cadaveric donor and is then transplanted into the patient's body to make the repair. Procedures using xenograft tissue, while not widely used in the United States other than for heart valves, involve recovering animal tissue, typically bovine or porcine, which is then transplanted into the patient's body.

The overall market in the United States for tissue repair and healing through the use of surgical implants, including metals, synthetics, and allografts, has grown considerably over the last several years, with revenues in the orthopedic and cardiovascular segments of this market exceeding $6.4 billion in 1999. In these segments, procedures using allografts, either conventional graft, bone paste, or specialty tooled tissues, totaled over 310,000 during 1999, accounting for revenues of over $410.0 million.

Processors of tissue supply allografts consisting of bone tissue and various soft tissues, including cardiovascular and connective tissues, to hospitals and surgeons for use in surgery. The need for tissue is increasing each year and currently is being served by approximately 30 tissue banks in the United States that process and/or distribute bone or cardiovascular allografts. We believe there will continue to be an increase in the use of surgical implants for repair and healing, and in particular allograft implants. These reasons include:

- the aging of the baby boom generation will result in a greater percentage of the population requiring tissue repair products;

- as life expectancies increase overall, the need for tissue repair products will increase;

- as patients and their families become increasingly proactive in determining the nature of the health care they receive and as they increasingly use the Internet to research health care alternatives, pressure will increase on medical providers for more natural healing alternatives;

- continuing emphasis placed on health and fitness in our society will continue to drive the growth of sports medicine-related tissue repair and tissue healing;

- increasing awareness of the safety and benefits of allografts will increase the acceptance of allografts by surgeons and patients; and

- as the federal and state governments continue to promote organ and tissue donation, more allograft tissue will become available.

TISSUE REPAIR TREATMENT OPTIONS

METALS AND SYNTHETICS. Historically, the medical community turned to metals and other synthetics for implant procedures, in part because they can be precision tooled for specific uses within the body. These metal and synthetic implants also can be designed for use with instrument sets designed specifically for the implant procedure. This permits faster and more precise surgeries, with the patient spending less time on the operating table, and allows the surgeon to use a uniform process that can be repeated easily.

24

Metal and synthetic technologies, however, have several shortcomings. One of the principal drawbacks to the use of these materials is that they do not promote bone "remodeling." As part of normal skeletal growth and maintenance, human bones renew themselves by a continual process of breakdown and build-up known as "remodeling," the same process involved in the natural healing of fractures. Metal is stiffer than bone and its use in orthopedics can cause "stress shielding," where the bone adjoining the metal does not remodel densely enough and becomes weak and fragile or disappears altogether. This problem can be of particular concern to elderly patients, who are more likely to suffer from osteoporosis. Also, a small percentage of patients display sensitivity to certain kinds of metals, such as nickel. Additionally, a number of synthetics tend to break down in the body and slowly drift from their initial implant position. Finally, metal pins and screws used in sports medicine procedures and small bone repairs have a number of significant disadvantages including a potentially painful removal process, uncertainty over the long-term consequences of a hard metal implant adjacent to joints, and tissue inflammation due to metal particulate debris.

XENOGRAFT. While used in other parts of the world, including Europe, the use of xenograft, or animal tissue, is not prevalent in the United States other than for heart valve replacements. One of the reasons for this is a higher risk of immune system response to implanted xenograft tissue due principally to the greater difficulty in cleansing the tissue, prior to implant, of all the substances that can cause an immune response. An additional reason for limited use of xenograft tissue in the United States is the perceived risk of disease transmission. One area, however, in which the use of xenograft tissue within the United States is prevalent is in the cardiovascular market. This is due mainly to its long accepted use in this market and the reduced difficulty in cleaning this particular type of tissue due to its thinness.

AUTOGRAFT AND ALLOGRAFT. In order to overcome the drawbacks to the use of metals, other synthetics and xenograft tissue, surgeons have increasingly turned to autograft and allograft procedures. Autografts and allografts, in contrast to metals and synthetics, are not only "osteoconductive," meaning they provide a scaffold for new bone to attach itself to, but can be "osteoinductive" as well, meaning they stimulate the growth of new bone. Historically, however, allograft and autograft procedures were not as easy to perform as procedures using metals and other synthetics since grafting procedures often required the surgeon to shape the tissue by hand, using standard operating room instruments prior to implanting the tissue. This requirement generally increases the amount of time required to be spent in surgery.

In addition to a lack of pre-tooling, another drawback to autograft procedures is that they require an additional and potentially dangerous surgery to harvest the tissue from a second site on the patient's body. In approximately 20% of autograft procedures, morbidity complications arise at the harvest site, with one out of four of these considered serious. Additional possible complications involved with autograft procedures include infection, pain, nerve and arterial injury, joint instability and hernia. Moreover, a patient may not have sufficient quantities of quality autograft tissue in other parts of his or her body available for transplant, a particular problem for elderly patients, who are more likely to suffer from osteoporosis which can compromise the quality of autograft tissue transplanted. Balanced against these disadvantages is the belief among some surgeons that a patient's own bone will remodel better than allograft, as well as lingering concern over the safety of allograft.

Since the introduction of modern, precision tooled processed allograft implants, however, more surgeons are turning to allograft procedures to treat musculo-skeletal and other tissue defects. Among the reasons for this shift are that patients can enjoy the benefits of an implant that promotes bone growth and better healing without having to undergo the potentially risky second surgery to obtain autograft tissue for transplant. In addition, surgeons increasingly prefer allograft implants since, with the introduction of precision tooled allografts and accompanying custom implant instrumentation, allograft implants now share the same convenience and ease-of-use advantages as metals and synthetics without the shortcomings. Also, concerns within the medical community about the transmission of HIV

25

and other infectious diseases through the use of allograft largely have been addressed and more surgeons now accept allograft as safe and effective. Finally, patients and their families increasingly have become more proactive in determining the nature of the healthcare they receive, due in part to the availability of healthcare information on the Internet, and increasingly prefer natural healing alternatives such as allograft.

An historical limitation within the tissue processing industry has been the requirement that tissue processing be done using clean room technology on a donor-by-donor basis in order to eliminate the risk of cross contamination of other donor tissue potentially caused by the contaminated tissue from just one donor. As a result, tissue processors are required to process donor tissue in a labor intensive process requiring extensive use of custom machinery and tools to create these allografts.

ALLOGRAFT MARKETS

The allograft market is limited by the supply of available cadaveric donor tissue. Of the 3.6 million deaths that occurred during 1999 in the United States, of which we believe 50% would have been eligible to donate, less than 0.4% actually resulted in donated tissue.

The allograft market can be broken down into a number of distinct segments, including orthopedic, urological and cardiovascular. The following table contains selected U.S. information for 1999 about the portions of these segments that can be addressed through the use of allograft implants:

                                                         TOTAL      ALLOGRAFT      ALLOGRAFT

ORTHOPEDIC MARKETS

The market for orthopedic tissue can be broken down into the following distinct segments:

- Spinal Fusions. The spinal market includes approximately 6.0 million people in the United States who seek treatment for back pain each year, of which approximately 650,000 to 700,000 result in surgery. Of this number, approximately 445,000 in 1999 resulted in a spinal fusion, approximately 90% of which included the use of an autograft or allograft implant. Autograft or allograft implants are commonly used to induce fusion in metal or bone spinal fusions. Surgeons also frequently use bone paste allografts as part of these procedures. The U.S. market for spinal fusions, including metals, synthetics, autograft and allograft, has grown considerably over the last several years. Total revenues in the United States for spinal fusions grew from approximately $484.6 million in 1997 to $735.7 million in 1999. Over the same period, the number of spinal fusion procedures performed in the United States grew from approximately 312,000 in 1997 to approximately 445,000 in 1999. Of these 445,000 procedures, approximately 113,000 involved the use of an allograft implant, accounting for approximately $226.0 million in revenues.

26

- Sports Medicine. The sports medicine market includes a number of segments, including arthroscopy, powered shavers, soft goods, video imaging and "procedure-specific" surgeries. The procedure-specific segment of this market that can be addressed through the use of allograft implants includes repairs to the anterior cruciate ligament, or ACL, rotator cuff, labrum, meniscus, posterior cruciate ligament, small bone repair, osteochondral repairs and wedge osteotomies. The number of procedures performed in the United States in the arthroscopy and procedure-specific segments of this market has grown from approximately 2.6 million in 1997 to over 3.0 million in 1999. The U.S. market for procedure-specific surgeries in the sports medicine market that used an implant has grown at a 6% average annual rate between 1997 and 1999. During 1999, there were approximately 870,000 procedure-specific surgeries in the United States that used an implant. Of these 870,000 procedures, approximately 52,000 involved the use of an allograft implant, accounting for approximately $73.0 million in revenues. We believe a significant number of surgical procedures which currently are treated only by abrasion or removal of soft tissue could benefit from allograft technologies, including a portion of the approximately 400,000 chondroplasty procedures performed in the United States in 1999. Worldwide, the procedure-specific segment of the sports medicine market grew from approximately $315.0 million in 1997 to approximately $360.0 million in 1999.

- Oral-Maxillofacial. The oral-maxillofacial market includes surgeries of the nose, face, jaw and mouth, including surgery for periodontal disease. These surgeries typically are either cosmetic or to treat disease or trauma. As with the sports medicine market, the aging population is fueling growth in this market by increasing demand for bone pastes used in jaw reconstruction and for support of dental implants as an alternative to dentures. Total revenues in the United States from oral-maxillofacial implants grew from approximately $195.0 million in 1997 to $224.0 million in 1999. During 1999, approximately 67,900 oral-maxillofacial procedures were performed in the United States, of which approximately 15,000 involved the use of an allograft implant, accounting for approximately $4.5 million in revenues.

- Conventional Tissue. The conventional allograft market encompasses tissues used in orthopedic surgery that have not been precision tooled and for which custom surgical instrumentation does not exist. Uses of conventional allograft include osteoarticular grafts for hip and knee reconstruction, ground bone and bone chips for trauma and bone filler, fashioned bone for various orthopedic procedures and soft tissue for ligament repair. During 1999, approximately 485,000 procedures were performed in the United States, of which approximately 125,000 involved the use of an allograft implant, accounting for approximately $66.0 million in revenues.

UROLOGICAL MARKET

The urological allograft market includes tissue implant procedures to treat urinary incontinence, primarily among older women. Urinary incontinence is a problem for more than 17 million Americans, approximately 85% of them women. A widely used procedure for treatment of this condition is re-suspension of the bladder neck with a "sling" of fibrous material. This sling can be made from synthetic materials or from various natural tissues. During 1998, approximately 250,000 procedures made use of this sling technique in the United States, of which approximately 37,000 involved the use of allograft implant, accounting for approximately $33.0 million in revenues. Although urinary incontinence can be improved in eight out of ten cases, less than half of those afflicted seek treatment.

27

CARDIOVASCULAR MARKET

The cardiovascular allograft market includes transplantation of human heart valves as an alternative to mechanical, synthetic or xenograft substitutes. An estimated 349,000 heart valve and vascular graft procedures for which allograft would be appropriate were performed in the United States in 1997, of which 95,000 were heart valve replacement procedures. Of the approximately 69,000 heart valve replacements for which more detailed data are available, approximately 6,500, or 9.4%, were performed using allograft. Total revenues in the United States from heart valve replacement procedures using allograft during 1997 totaled approximately $41.0 million.

COMPANY OVERVIEW

We are a leader in the use of biologics and tissue-based innovations that are used to repair and promote the natural healing of human bone and other human tissues. Using core human physiology--the basic biology of natural tissues as they function in the body--our allografts are improving surgical outcomes. Our goal is to replace conventional implant approaches, including metals, synthetics and autograft implants, with allograft and for our allografts to become the implant of choice for tissue repair. We are a leading worldwide provider of comprehensive healing and biologic tissue products in a broad range of markets. In addition we are the largest processor of precision tooled allografts in the United States, with our allografts being distributed in all 50 states and in nine countries internationally. We also continue to be one of the leading processors of conventional allograft in the United States.

We process human musculoskeletal and other tissue, including bone, cartilage, tendon, ligament, pericardial and cardiovascular tissue in producing our allografts. These tissues are then used to repair and promote the healing of a wide variety of bone and other tissue defects, including spinal vertebrae repair, musculoskeletal reconstruction, fracture repair, periodontal repair, urinary incontinence and heart valve disorders. Our current grafts range from conventional allografts to precision tooled grafting material, including bone dowels, wedges, pastes and pins, urological allografts and heart valves. During 1999, we shipped over 90,000 processed allografts, used in an estimated 60,000 procedures. Often, more than one allograft is used in a given procedure.

We have one of the most extensive tissue recovery programs in the United States, recovering bone or cardiovascular tissue from over 4,000 human donors during 1999, up from over 2,300 in 1998 and 1,500 in 1997. We believe our network of recovery groups accounted for approximately 34% of the human tissue recovered in the United States during 1999.

The following table outlines the markets we serve and the percentage of our revenues, net of management services fees, from core operations during 1998 and 1999 for these markets:

In addition, we will enter the cardiovascular market through our acquisition of the tissue processing and distribution business of Alabama Tissue Center, which had approximately $0.5 million in revenues during 1999.

We pursue a market-by-market approach to distribution of our allografts, including strategic distribution arrangements in order to increase our penetration of selected markets. We have an alliance

28

with Medtronic Sofamor Danek in the spinal market, with Exactech, Inc. in portions of the non-spinal molded bone paste market, and with C.R. Bard, Inc. in the urological market.

Using our proprietary, patent pending BioCleanse system, we believe we are the only tissue processor currently able to safely process tissue from multiple donors simultaneously. This system, which kills or inactivates all classes of conventional pathogens, viruses, microbes, bacteria and fungi, and which cleanses tissue both before and after processing, allows us to safely process tissue from up to 100 donors at the same time thereby significantly increasing the efficiency of tissue processing. In addition, our BioCleanse system is able to remove blood, fats, lipids and cellular debris from the tissue we process more successfully than traditional aseptic processing. We believe the removal of all blood, fat, lipids and cellular debris results in faster patient healing since it eliminates the need for the patient's body to remove these substances using natural processes following surgery. In contrast to traditional aseptic processing, our BioCleanse system also permits us to process tissue at lower average cost, and to safely and economically process tissue from donors and age groups that might not have been feasible without BioCleanse.

OUR STRATEGY

Our strategy is to be the leading worldwide provider of biologics and tissue-based innovations that repair and promote the natural healing of human bone and other tissue. The following are the key elements of our strategy:

CONTINUE PRODUCT INNOVATION TO CREATE NEW ALLOGRAFTS AND PROCEDURES. We pioneered the development of precision-tooled allograft bone tissue implants. We plan to continue to use this expertise to strengthen and build upon our existing platform of allografts and procedures within our core markets, and to enter or create new markets for our current and future allografts. We do this by fostering innovation in our research personnel and product development staff. We also set corporate goals that stimulate product innovation, such as launching at least one new allograft every quarter within each of our markets.

IDENTIFY ADDITIONAL SURGICAL APPLICATIONS FOR OUR TECHNOLOGIES AND PRODUCTS. While we intend to continue to introduce new grafts into our traditional core markets of orthopedics, urology and cardiovascular, we also intend to leverage our expertise in the area of biologic tissue implants to develop new technologies and to enter new markets, including the application of dermal allografts for reconstructive and cosmetic procedures. We plan to make use of our existing infrastructure, including our extensive research and development capabilities and sales and marketing infrastructure in order to establish our presence in these growing markets. In addition, we plan to make selective acquisitions in order to develop or expand our presence within particular markets, such as our recent acquisition of the tissue processing and distribution business of the Alabama Tissue Center which allowed us to enter the cardiovascular market.

CONTINUE PROCESS INNOVATION TO ESTABLISH PRODUCT DIFFERENTIATION. We intend to continue to reevaluate and enhance the processes we use in our business to increase efficiency and maintain our competitive advantage. Our proprietary BioCleanse system allows us to safely process, sterilize and virally inactivate tissue from up to 100 donors at the same time. In addition to the efficiencies and other advantages our BioCleanse technology permits, it also provides us with a number of significant research and development advantages, including the opportunity to infuse allografts with growth factor agents. Additionally, we intend to continue to introduce greater automation into the processing of our allografts in order to further enhance efficiencies and reduce processing costs.

EXPAND OUR EXTENSIVE TISSUE RECOVERY PROGRAM AND EMPLOY NEW TECHNOLOGIES TO MAKE BETTER USE OF EXISTING TISSUE SUPPLY. We intend to continue our strategy of entering into alliances with tissue sources to ensure continued growth of our tissue availability and to introduce these sources to successful tissue

29

recovery programs within our alliance to raise the level of tissue donation. We also intend to make selective acquisitions, such as our recent acquisition of Georgia Tissue Bank, to further enhance our tissue recovery efforts. Additionally, we plan to expand our tissue recovery efforts internationally to support our projected growth in those markets. We also seek to increase the availability of donor tissue by further improving the efficiency of our tissue processing procedures and by continuing our efforts to increase the level of tissue donation. We will continue to instill in our employees and alliance partners our philosophy of honoring the gift of tissue donation and using that gift responsibly to help as many patients as possible. Finally, we plan to augment the supply of human tissue through the use of alternative tissues, such as bovine and porcine tissue.

EXPAND OUR SALES AND MARKETING CAPABILITIES. We believe a significant opportunity exists to expand distribution of our grafts and technologies. We intend to continue to expand our presence both domestically and internationally by increasing the level of our sales and marketing activities, in the countries in which we presently operate, as well as in additional countries. We plan to continue to enter into new distribution relationships, expand existing distribution relationships, and augment our internal sales and marketing capabilities to enhance our penetration in the markets we serve. In addition, we intend to continue to educate and support the medical community by creating an Internet-based ordering and information system for surgeons. Traditional order placement will remain in place but as e-commerce becomes increasingly important within the medical community, we believe our on-line ordering system will provide a fast and convenient venue for surgeon orders and information. The level and detail of information made available through our Web site will be adjusted based upon need thereby resulting in an on-line product which is educational and useful to the medical community.

ORTHOPEDIC ALLOGRAFTS

SPINAL. Our principal spinal allografts are our patented MD-Series Threaded Bone Dowels, our patent-pending Cornerstone SR Wedge, Tangent Cortical Bone Wedge and patent-pending Precision Cortical Bone Wedge. These allografts, which are precision machined, are eventually replaced by the patient's own bone through the remodeling process, typically over a one- to two-year period. During 1999, we shipped more than 43,000 spinal allografts, excluding bone pastes, which accounted for approximately $14.1 million of our net revenues.

Our MD-Series Threaded Bone Dowels are used by surgeons to help restore the anatomical relationships between the disc, facet joints, vertebral bodies and foramina. As a result of trauma, abnormal wear and tear, or the aging process, damage or degenerative changes to the vertebral disc and facet joints may occur and progress over time. Among other things, this can result in pinched nerves, disc injury and severe pain. Several important features of our MD-Series dowels assist in reestablishing spinal stability and reducing pain. First, our dowels are threaded, providing rigid interface above and below the vertebral body, allowing the surgeon to restore normal alignment and provide greater stability. This alignment and stability following surgery contributes to reducing pain, greater functionality and reduced risk of reoccurrence. Second, the cylindrical shape of our dowels, together with accompanying threads, provides greater surface area contact at the junction between our graft and the patient's bone, thereby enhancing healing. Third, the pre-cut precision size and shape of each graft helps in reducing surgical time. Evolving from our early smooth cortical dowel, our present line of dowel allografts is suitable for higher load bearing situations, making them more useful for areas such as the lumbar spine.

Our Cornerstone SR Wedge, as with our MD-Series dowels, is used in similar cases in the cervical area of the spine, but is tapped in place, not threaded. Our Tangent Cortical Bone Wedge and Precision Cortical Bone Wedge allografts are also tapped or "impacted" in place. Both grafts are specially designed and contoured to promote stability and minimize disruption of the posterior elements of the spine.

We currently have several spinal allografts in development, including demineralized and partially demineralized cortical bone for ligaments for use in fixating the vertebral bodies following a spinal fusion surgery, as well as bovine versions of existing precision tooled allografts.

SPORTS MEDICINE. Our product focus in the sports medicine market addresses the highest volume procedures in sports medicine, primarily in the shoulder and knee. Our principal sports medicine allografts are our patented interference screws, patent-pending pre-shaped bone-tendon-bone ligaments, patent-pending meniscus allografts and patent-pending pins. These grafts, used for the repair of sports-related injuries such as a torn anterior cruciate ligament are precision tooled to fit surgeons' requirements, allowing the surgeon to perform the procedure without having to custom shape the implant material. Many of our sports medicine allografts are designed for specific instrumentation, making them easier and/or faster to implant. These grafts can also be osteoinductive, meaning they promote the growth of new bone. During 1999, we shipped approximately 2,500 sports medicine allografts, excluding bone pastes, which accounted for approximately $0.3 million of our net revenues.

We currently have several sports medicine allografts in development, including soft tissue tacks used for reconstruction of soft tissue tears such as rotator cuff injuries, non-frozen osteochondral allografts used for repair of articulating surfaces and joints, bone suture anchors used for securing sutures to bone, pre-shaped achilles tendons and quadriceps tendons. We also are developing ligament alternatives made from under-used tissue with demineralized tissue technology for use as ligament and tendon replacements, as well as soft threaded interference screws and wedges used for knee re-alignment. At the same time, we are developing the customized instrumentation to be used by surgeons implanting our sports medicine allografts.

32

BONE PASTE. Bone paste allografts, moldable and injectable, are principally used in fracture treatment, bone and joint reconstruction and periodontal applications. Our principal products in this market are our patent-pending Osteofil Injectable Bone Paste and our patent-pending Opteform Moldable Bone Paste, both of which are composed of demineralized bone matrix and biologic gel carrier. Our Opteform Moldable Bone Paste and new patent-pending Osteofil ICM Bone Paste also include cortical cancellous chips. Importantly, all of our bone pastes are osteoinductive and every batch is tested for osteoinductivity before release. In addition, our bone pastes are uniquely "sticky" and not water soluble and therefore will not easily disperse or migrate within a patient's body, a potential problem with other currently available bone pastes.

In addition, our Osteofil Injectable Bone Paste is dispensable through a syringe, an advantage not shared by all bone pastes. Our bone pastes have a gelatinous consistency which hardens at or below body temperature. Our Opteform Moldable Bone Paste, which is pliable before hardening, is shaped in molded forms useful for general orthopedic applications, typically hip and knee replacements. During 1999, we shipped more than 19,000 bone paste allografts, which accounted for approximately $5.2 million of our net revenues.

We currently have several bone paste allografts in development, including pastes for the potential use in vertebroplasty, which is the repair of degenerated vertebral bodies. We also are currently in the final stages of development of bone pastes that can be stored and distributed at room temperature and then mixed in the surgical arena, eliminating the need to keep the material frozen prior to use.

CONVENTIONAL ALLOGRAFTS. Our conventional allograft business includes a wide variety of allograft categories including our osteoarticular grafts, such as our frozen femoral heads used for oncological procedures and hip and knee reconstruction. We also produce certain types of blended and milled bone allografts, such as our demineralized bone matrix, cortical cancellous chips and ground cancellous chips, used in total hip and knee replacements and for various trauma. Additionally, we produce various types of fashioned bone, such as our fibular wedges and iliac crest wedges, used for various orthopedic procedures, as well as various soft tissue implants used for ligament and articulating surface repair, such as non-precision tooled ligaments and tendons.

This growing market is important to us since it allows us to make the best possible use of the gift of tissue donation and allows us to convert a significant portion of the conventional allografts we distribute into precision tooled allografts. We currently have a pre-ground femoral head allograft in development to be used in hip revision surgery. During 1999, we shipped more than 16,000 conventional allografts, which accounted for approximately $9.0 million of our net revenues.

ORAL-MAXILLOFACIAL ALLOGRAFTS. Our principal oral-maxillofacial products are our patent-pending Regenafil Injectable Bone Paste, our patent-pending Regenaform Moldable Bone Paste and our patent-pending pericardium membranes. Our Regenafil and Regenaform bone pastes are similar to our Osteofil and Opteform bone pastes. Our allografts have a number of uses in oral-maxillofacial medicine, including use in procedures to rebuild portions of the jaw to permit the use of dental implants. Prior to the use of these allografts, many patients receiving dental implants would instead be limited to dentures or bone would have to be harvested from their hip to complete the reconstruction. Our pericardium membrane is used to cover the site where bone paste, or autograft or allograft bone chips, have been placed, preventing the growth of fibrous tissue from filling the space and allowing the bone to remodel. During 1999, we shipped more than 1,500 oral-maxillofacial allografts, which accounted for approximately $0.2 million of our net revenues.

We currently have several oral-maxillofacial allografts in development, including demineralized plates which could be used in place of metal plating in oral and maxillofacial surgery, an orbital floor repair system for facial reconstruction and Regenaderm, our planned dermal membrane for use in the oral-maxillofacial market.

33

UROLOGICAL ALLOGRAFTS

Our principal allograft in the urological market is our FasLata, which is used primarily to treat urinary incontinence through re-suspension of the bladder neck. This graft is fashioned as a "sling," processed from fascia lata, the fibrous tissue covering the large muscles. Prior to the use of sling procedures, there was not an effective treatment for urinary incontinence which is caused by a specific defect to the urethra. Demand for useable tissue in this market far exceeds the supply. Additional applications we are developing for tissue in this market are soft tissue "anchors" which are precision tooled from cortical bone, and slings fashioned from alternative tissue such as dermis. During 1999, we shipped more than 12,000 urological sling allografts, which accounted for approximately $1.9 million of our net revenues.

CARDIOVASCULAR ALLOGRAFTS

Our principal cardiovascular allograft is our heart valve allograft, which is used to replace a patient's own heart valve during coronary surgery. Additional applications we are developing for tissue in this market are pulmonic patches for faulty arteries, and veins for vascular tissue replacement. During 1999, the tissue processing and distribution business of Alabama Tissue Center we are acquiring shipped approximately 70 cardiovascular allografts, generating approximately $0.5 million in revenues for that year.

TISSUE RECOVERY

BACKGROUND

Tissue recovery is the actual removal of tissue from a donor. Tissue recovery personnel recover tissue within 24 hours following a donor's death using surgical instruments and aseptic techniques similar to those used in hospitals for routine surgery. Techniques for recovery emphasize minimizing any physical alteration of a donor's body. Recovered tissue is placed on wet or dry ice and then transported by the recovery personnel to the tissue bank.

Under applicable U.S. law, human tissue cannot be sold. However, the law permits the recovery of certain costs, such as those involved in recovery, processing and storing tissue and for the advancement of tissue processing technologies, the types of activities in which we are involved.

Our network of donor recovery groups recovers a variety of tissue types from donors including tissue from the fibula, femur, tibia, humerus, ilium, pericardium, fascia lata, and hearts for valve recovery. We screen recovered tissue in numerous ways to guard against transmittable diseases. This screening process includes evaluation of risk on the basis of donor lifestyle, interviews with the donor's family and physical examination of the donor. We also perform biomedical testing at various stages during the conversion of the tissue into implantable tissue, using FDA licensed and other tests for known viruses and pathogens.

In addition to screening for safety of the tissue, tissue banks develop screening criteria to help them decide what tissue grafts may be processed from each donor. We believe our biomechanical and tissue suitability screening standards are unique in the industry. Unlike traditional tissue bank guidelines, which include arbitrary criteria such as a donor's age as a determinant of suitability, our standards and criteria are based on scientifically validated testing and studies. Tissue from each donor is first examined, including radiographic and physical examination. In addition, for each type of precision tooled graft to be produced, we perform a biomechanical evaluation. Depending upon the type of graft, our statistical validations include tests such as impact and tensile fatigue, static compression and torque, and pull-out strength. For our bone pastes, we test each batch in animals to ensure that the paste remodels bone, a step we believe is not taken by any other tissue bank. Our scientific screening standards, together with our tissue processing technology, allow us to make use of

34

this recovered tissue to the fullest extent possible. They also ensure the suitability of the tissue to be used for the graft being processed. For example, we routinely reject some weight-bearing grafts from donors under the age of 50 since our tests indicate those grafts would not have adequate mechanical properties, while traditional screening protocols might accept any donor under the age of 55. Unlike traditional screening protocols, our screening standards allow a greater range of age among donors, and our BioCleanse system permits us to safely and economically process tissue even from lower-yielding donors. This provides the maximum benefit for the donor family as well as the donor recipient.

TISSUE RECOVERY EXPANSION

We have one of the most extensive tissue recovery programs in the United States, recovering tissue from over 4,000 donors during 1999, compared to 2,300 in 1998 and 1,500 in 1997. At present, there are approximately 30 tissue banks in the United States that process and/or distribute bone or cardiovascular allografts, the majority of which also function as donor recovery groups. Donor recovery groups typically promote tissue donation, educate hospitals and other institutions regarding tissue donations, support the family of the donor, and physically recover and transport the donated tissue. Donor services group staff members are trained to understand and deal with the emotional elements involved in interacting and supporting the families of donors at their time of loss.

Of the approximately 80 donor recovery groups in the United States that recover bone tissue, we have sourcing arrangements with more than 35 including the University of Florida Tissue Bank, Inc., Allosource, Inc., Community Tissue Services Dayton, Allograft Resources of Wisconsin and Tissue Banks International. Of these 35 donor recovery groups, we have exclusive agreements with five, non-exclusive agreements with 16, and exclusive management services agreements with four. The remaining groups work with us on a non-contract basis or through relationships with other recovery groups in the network. This extensive supply alliance allowed us to ship over 90,000 processed allografts during 1999, used by surgeons in an estimated 60,000 procedures. Often, more than one allograft is used in a given procedure.

In particular, our exclusive relationship with the University of Florida Tissue Bank continues to provide us with a large supply of tissue for processing and distribution. We plan to continue to enhance our recovery programs in order to support our future growth by adding additional donor recovery groups to our supply alliance, particularly those presently acting as exclusive suppliers to others in the industry. Additionally, we may from time to time consider additional acquisitions of tissue banks to further enhance supply, such as our recent acquisition of Georgia Tissue Bank.

During 1999, of the more than 3.6 million deaths in the United States, of which we believe 50% would have been eligible to donate, less than 0.4% actually resulted in donated tissue. To the extent possible, we work with management of the tissue banks with which we have relationships to assist them in increasing the level of tissue donation. In areas where we have had active involvement with donor recovery groups over an extended period of time, we have increased the recovery rate to in excess of 4.0%. This involvement may include entering into a management services agreement with these tissue banks. While the terms of these agreements vary, often they involve assisting with the design or improvement of the tissue bank's donor services group to increase the level of donation.

Our strategy is to further expand our tissue recovery operations in our targeted regions, which include Florida/Georgia, Indiana/Michigan and New York, through increased professional and public education. We also plan to continue to establish relationships with medical examiners, hospitals and funeral homes in these areas. We presently have agreements with 10 donor recovery groups within these three targeted regions, two of which are management services agreements. We have a four member team operating in each of these regions consisting of one representative from each of sales, marketing, donor services, and our subsidiary, Georgia Tissue Bank. These teams are responsible for providing services to the recovery groups presently under management services agreements and also to seek to enter into management services agreements with other donor recovery groups in these regions.

35

Internationally, we currently are involved in expanding tissue recovery relationships in seven countries in order to support our planned international growth. In addition we currently process tissue from Europe under our agreement with Tutogen. We also have planned joint efforts with foreign partners for tissue recovery in Spain, Portugal, France, Austria, Switzerland and Italy. Tissue recovery internationally presents a number of different challenges than in the United States, including different laws, societal pressures and local customs.

We also plan to continue to recover tissue though affiliations with funeral homes, which involves presenting families of the deceased with the option of tissue donation and supplying them with the information necessary to make an informed decision. While we reimburse funeral homes for use of their facilities and materials, the principal incentive for funeral homes to participate in an affiliation with us is their ability to offer families of deceased the chance to help others through the gift of tissue donation. Since approximately two-thirds of all deaths occur outside of a hospital, we believe our strategy of recovering donor tissue from funeral homes to be important to increasing the overall level of tissue donation. Tissue recovered from funeral homes is subject to the same requirement as in a hospital setting, that it be recovered within 24 hours following a potential donor's death.

We also are exploring the use of bovine tissue in the orthopedics markets and have arrangements to procure bovine tissue from a "closed herd" of cattle. This closed herd is one for which the source, age and lineage of each animal has been documented for more than seven years, with health and pedigree records reviewed and managed so that no animal of the herd has been suspected of a disease threatening to humans, and in which each animal is kept separated from animals not in the closed herd. We already use small amounts of gelatin derived from porcine sources in the production of our bone pastes.

Donor recovery groups are part of relatively complex relationships. They deal with donor families, are regulated by the FDA and are often affiliated with hospitals, universities or Organ Procurement Groups. Our relationship with donor recovery groups can be impacted by some of the factors that impact these donor recovery groups, and that could have an effect on the supply of tissue to us. For example, during March 2000, we became aware of letters from an anonymous source being circulated which made allegations against Allograft Resources of Wisconsin, or ARW, one of the donor recovery groups with which we have a tissue recovery agreement. One of these letters was addressed to the FDA and included specific alleged violations of federal regulations by ARW, including claims that tissue recipient safety had been compromised. We promptly dispatched a team to visit ARW to review its donor records and safety procedures. We also contacted the FDA, and a team of FDA auditors conducted its own inspection of ARW. In addition, the board of directors of ARW engaged a law firm to interview every employee and a number of former employees of ARW about the allegations made.

The FDA's inspection resulted in the issuance of an inspection notice, and none of the observations noted raised concerns over the safety of ARW tissue with respect to the issues raised in the anonymous letters. Six observations were noted, however, concerning documentation and record keeping, and corrective actions were proposed. Neither the FDA, our own internal investigation nor the law firm engaged by ARW found evidence to support the safety allegations made against ARW. We plan to continue monitoring the situation with ARW, as well as the other donor recovery groups with which we have recovery arrangements.

TISSUE PROCESSING

Following recovery of tissue using recovery techniques designed to minimize physical alteration of the donor's body, recovered tissue is placed on wet or dry ice and then transported by the recovery personnel to the tissue bank. After the recovered tissue arrives at the tissue bank, we place the donor tissue in freezer storage until we complete applicable quality assurance procedures and protocols, including review and approval by one of our in-house medical directors, each of whom is a medical

36

doctor. We then move donor tissue into processing based upon the demand for certain recoverable tissues.

We surgically process tissue into numerous individual types of implantable allografts, with each graft being sized, evaluated and labeled. Some allografts have a much higher demand than do others, and those generally are distributed as soon as we complete processing and quality assurance. We store the remaining implantable allografts at our facility, awaiting distribution on an as-needed basis.

A variety of allografts can be derived from a single bone. For example, from a femur, we are able to produce a number of allografts including bone dowels, interference screws, wedges and bone pastes. The following illustration shows some of the allografts that can be produced from the femur:

[Illustration of femur bone appears here, depicting the various allografts that we process from the femur]

Other than a number of conventional grafts, bone pastes and soft tissue which are aseptically processed through conventional means, we process donor tissue initially through our proprietary BioCleanse system to begin the sterilization process and to remove all blood, fat and cellular debris. We believe the removal of all blood, fat, lipids and cellular debris results in faster patient healing since it eliminates the need for the patient's body to remove these substances using natural processes following surgery. Our BioCleanse tissue processing system is a proprietary, multi-step, patent-pending tissue cleaning process, using ultrasonic, temperature and pressure cycle controls.

Our validation studies of the BioCleanse system show this process kills or inactivates all classes of conventional pathogens, viruses, including HIV, microbes, bacteria and fungi present in the tissue, while retaining the tissue's useful properties. Specifically, the scope of the validation we performed on our BioCleanse system included viral inactivation studies demonstrating complete clearance of relevant enveloped and non-enveloped viruses including HIV, hepatitis A, porcine parvovirus, bovine viral diarrhea virus and pseudorabies. Additionally, the validation study showed that the system effectively eliminates both endogenous and adventitious microbial contamination from within the matrices of allograft. The validation included testing against a panel of known microorganisms including BACILLUS STEAROTHERMOPHILUS, recognized as the most resistant microbial species. The BioCleanse process also was shown to remove greater than 99.99% of blood and fat from allograft material. The resulting tissue passes the United States Pharmacopia standard test for sterility and has been validated to attain a Sterility Assurance Level of 10(-6). Biomechanical and biocompatability testing of the BioCleansed allografts demonstrated that the functionality of the allograft was not impaired by the BioCleanse process. Based on these studies, our BioCleanse technology produces sterile allografts, which we believe

37

to be the safest processed donor tissue in the industry. We believe the effectiveness of BioCleanse in inactivating viruses such as HIV and other harmful pathogens helps to allay the fears of disease transmission associated with allograft procedures.

Because the BioCleanse system is completely automated, we are able to reproduce our sterilization results in every group of tissue that we process. Our BioCleanse technology is also cost-effective since we are able to safely process the tissue of up to 100 donors simultaneously in our system, eliminating the risk of cross contamination to a less than one in one million probability of cross contamination. We believe we are the only tissue processor able to safely process tissue from multiple donors simultaneously.

Tissue to be precision tooled for creating our line of specialized allografts is removed from inventory after initial BioCleanse processing and placed into production for the creation of precision machined allografts. Our processing and manufacturing facilities include a suite of four class 10 certified clean rooms, six class 100 clean rooms and four class 1000 clean rooms. We recently introduced the use of automated machinery in the precision tooling of our line of proprietary allografts, a task previously performed by our staff of tissue technicians using customized tools and equipment. This increased use of automation allows us to produce precision tooled allografts faster and more efficiently, while significantly reducing processing costs. Automation also results in higher quality precision tooled allografts since our machines are able to reduce the risk of human error by repeating accurately and uniformly the tooling process countless times, instead of each graft being the product of the tissue technician's skill.

Our tissue processing equipment also includes our proprietary lathes which use hydro-infused drilling technology and custom tooling employed to thread our cortical dowels and produce bone paste. Other custom equipment includes clean-room milling machines, saws, grinders, dies and mills. After our operators and technicians precision tool the donor tissue, we repeat the BioCleanse process to complete the sterilization process. We are ISO 9001 certified, an internationally recognized standard of quality assurance in product design, development and production. Our biomedical laboratory is certified under the Clinical Laboratory Improvements Act, or CLIA. CLIA is intended to ensure the quality and reliability of clinical laboratories in the United States by mandating specific standards in the areas of personnel qualification, administration, participation in proficiency testing, patient test management, quality control, quality assurance and inspections.

MARKETING AND DISTRIBUTION

In the spinal market, we plan to continue our strategic distribution alliance with Medtronic Sofamor Danek. We have two management services agreements with Medtronic Sofamor Danek under which they provide management services in the distribution and marketing of our spinal allografts and Osteofil bone paste for spinal uses. Medtronic Sofamor Danek's 350 sales representatives interact directly with surgeons, providing the necessary instrumentation, customer support, surgeon education and training, and marketing for our current spinal allografts. In exchange for its management services, we pay Medtronic Sofamor Danek services fees. Under the agreement for management services on our bone pastes, the amount of this service fee is 60% of the amount charged to each customer until November 1, 2000, after which time the fee increases to 65%. This agreement expires upon the later of May 2018 or the expiration of our bone paste patent. Under the agreement for management services on our current line of spinal allografts, we pay Medtronic Sofamor Danek a service fee equal to 70% of the amount charged to each customer. Under this agreement, Medtronic Sofamor Danek has a 60-day right of first refusal to license our new allografts or developments relating to spinal and cranial medical procedures. This agreement expires in July 2021. Under these agreements, subject to certain exceptions, Medtronic Sofamor Danek also has exclusive rights to provide management services in the distribution of our spinal and cranial allografts internationally, though it has not done so to date.

38

Our allografts are distributed in all 50 states and in nine countries internationally. In the United States, we have 23 independent distributors, which distribute our allografts through approximately 150 sales representatives, specializing in general orthopedics, complemented by our internal sales and marketing staff of 26 people. Internationally, we have six distributors which distribute our allografts through approximately 320 sales representatives. We pursue a market-by-market approach to distribution, including strategic relationships in selected markets, in order to increase our penetration of these markets.

In the general orthopedics market, our pre-molded bone pastes are distributed by Exactech in the United States through its network of 50 sales agencies using approximately 139 sales representatives. We also distribute our sports medicine allografts through our network of 23 independent distributors and 150 independent sales representatives who distribute directly to hospitals and surgeons in their exclusive territory. Under the terms of our distribution arrangements, these distributors are entitled to receive a commission for the revenues they generate and have the right to maintain their status as the exclusive distributor in their territory if they reach a specified annual quota.

We distribute our bone pastes not used in the spinal and portions of the sports medicine markets through our independent network of 23 distributors specializing in general orthopedics. We also are considering creating a direct sales force in key U.S. markets to augment sales of our Osteofil Injectable Bone Paste.

For conventional tissue distribution, we use our network of 23 independent distributors with more than 150 independent sales representatives. Distributors and sales representatives receive a commission for the revenues they generate and have the right to maintain their status as the exclusive distributor in their territory if they reach a specified annual quota. Our recent acquisition of Georgia Tissue Bank significantly increased the size of our distribution organization for conventional allografts.

We use direct distribution for the oral-maxillofacial market, with an emphasis on the periodontal market. We have created direct mail product information sheets, and we attend trade shows to increase the exposure of our allografts. Our six person marketing staff supports these marketing efforts by speaking at various clinics and universities.

In the urological market, we have an exclusive distribution agreement with C.R. Bard providing for the marketing and distribution of our urological allografts. Under the terms of this agreement, we ship our urological allografts directly to C.R. Bard's customers. In return, we receive reimbursement for shipping charges and a transfer fee which is 40% of the amount charged to the customer. In order to remain our exclusive distributor of these allografts, C.R. Bard is required to achieve a specific annual distribution quota. C.R. Bard has an exclusive 90-day right to negotiate an agreement for the distribution of any new technology, invention, process or application we may develop in the future for the treatment of urinary voiding dysfunction or pelvic tissue defects. This agreement expires in June 2008, subject to a provision providing for automatic renewal.

In the cardiovascular market, we intend to distribute our heart valve allografts through one or more distributors, initially within the southern United States and then expanding to other regions after securing adequate supply of tissue.

Our current and planned international distribution strategies vary by market, as well as within each country in which we operate. For example, we distribute only a portion of our line of allografts within each country. We also have recently signed distribution agreements with distributors in several key markets internationally. These include Plus Endoprothetik, in Germany, Austria and Switzerland, Korean Bone Bank in South Korea, Best Medical, Ltd. in Turkey, Medical Development S.A., in Greece, ACORN Ltd. and UFTB Italia in Italy, and CH Werfen in Spain and Portugal.

We intend to enter into additional markets around the world, including France, the United Kingdom and Japan. During 1999, 2.6% of our net revenues were derived from international markets.

RESEARCH AND DEVELOPMENT

We plan to continue to develop new allografts and technologies within the orthopedics, urological and cardiovascular markets, and to develop additional tissue-related technologies for other markets. To accomplish this, we intend to continue to make use of our core technologies and processes, which include:

- precision machined cortical bone;

- osteoinductive allograft bone pastes;

- our patent-pending proprietary BioCleanse system;

- segmentally demineralized bone allografts;

- viable osteoarticular grafts designed to fit specific surgical instruments;

- growth factors to stimulate bone or tissue growth;

- cortical allografts assembled from various smaller bone pieces; and

- xenograft bone treated to reduce material that could cause immune responses.

We believe that these core processes and technologies, including our BioCleanse system, have far reaching uses in new markets including the use of biologic tissue implants for growth factor delivery.

As of March 31, 2000, our research and development staff consisted of 22 professional and technical personnel, including three with PhDs or MD/PhDs and six with masters of science degrees, in disciplines such as mechanical engineering, materials sciences, biochemistry, biomedical sciences, biomaterials and organic chemistry. Our research and development staff work closely with surgeons in the development of new techniques and procedures related to tissue healing.

PRODUCT DEVELOPMENT PROJECTS

We are involved in numerous development projects, including new machined orthopedic allografts for the spine and sports medicine areas which allow us to expand our existing line of allografts. Among our current product development projects are:

- Interference Screw ST--This "soft" threaded interference screw would represent an expansion to current offerings in the ACL reconstruction market.

- Preshaped Tendons for Reconstruction--Achilles and quadriceps tendons with pre-shaped bone blocks intended to allow for easier replacements and reduced surgical time.

- Alloanchor RC--Targeted at the shoulder market, this allograft, similar to a "suture anchor," could represent an allograft alternative to current metal and resorbable suture anchors.

- Osteofil II--A version of our Osteofil bone paste that can be transported and stored at room temperature by separating the elements of the paste and then allowing for mixing in the surgical room.

- Osteochondral plugs--These non-frozen viable allografts could be available in a range of plug sizes for knee repairs and will represent a new method for transplanting fresh donor cartilage.

- Tibialis tendons--An increasing popular solution for ACL reconstruction, this graft could simplify the current surgical procedures for repair of this tendon.

- Suture anchor extensions--These grafts are further adaptions of the initial Alloanchor RC, designed in smaller sizes for other procedures in the shoulder and small joints.

- HTO wedges--This graft is designed for correction of lower extremity misalignment, a cause of loading imbalances in the knee. This precision tooled allograft would reduce the amount of "customization" normally required in this procedure.

40

- Soft tissue tacks--These bone tacks will be used to reestablish soft tissue to bone attachments. The allograft tack achieves surgical repairs without the need for suture.

- Complementary instrumentation--Instruments required for use with our allografts during the surgical procedure are being designed to ease the demands of the surgical procedure.

- Pre-ground femoral heads--This allograft, used in hip revision surgery, should reduce the amount of time spent in surgery by freeing surgeons from the necessity of grinding femoral head tissue in the operating room.

- Dermis-based urological sling--Processed dermis used for "sling procedures" are essentially decellularized dermal allografts. Our BioCleanse process is, in addition to a tissue cleaning process, a decellularizing process. Studies are underway to determine the effectiveness of the BioCleanse process in producing such a decellularized allograft which could have application for urinary slings, duraplasties, pleuralplasties, gastric patches, burn treatment, and reconstructive facial surgery.

RESEARCH AND TECHNOLOGY PROJECTS

We also are working on a number of long-term research and technology projects that we believe hold potential. Each of these projects, however, is at a very early stage and we cannot be sure that we will ever develop a working technology from this research. Among our current long-term research and technology projects are:

- Tendon replacement--This patent-pending technology would reconfigure hard, cortical bone tissue into a tendon-like structure with tendon-like strength. Until now, most natural tissue tendons used in sports medicine are transplanted tendons, either autograft or allograft. Allograft tendons, however, continually are in short supply. The replacement under development has a wide range of applications, and would remodel into the patient's own tendon over time.

- Composite allograft--This technology involves the joining of two or more separate pieces of machined bone. This allows for a wider range of design configurations and potentially could result in higher yields per tissue donor since the bone's anatomy would no longer be a limiting factor in the size and shape of a given allograft.

- Demineralized strip/plate for facial applications--We are researching methods for processing bone into plates and strips that are somewhat flexible, yet retain a certain degree of stiffness, using demineralization or partial demineralization. These plates and strips, especially advantageous in pediatric surgeries, could then be used for a variety of oral-maxillofacial applications including orbital floor and nasal reconstruction.

- Reduced antigenicity bovine bone--We are conducting tests and validations on the use of our BioCleanse system to reduce antigenic materials (materials that can cause a rejection or immune response) from bovine tissue. A variety of grafts could potentially be processed from bovine bone. We are pursuing CE Mark and 510(k) clearance for bovine versions of the Cornerstone SRs, Tangents, Precision ALIFs, Interference screws, suture anchors and CT.

COMPETITION

Competition in the bone and tissue healing industry is intense and subject to rapid technological change and evolving industry requirements and standards. Generally, competitors within the industry compete on the basis of design of related instrumentation, efficacy of products, relationships with the surgical community, depth of range of implants and pricing. Allograft implants compete with autograft, metals and synthetic tissues, as well as with alternative medical procedures. For the foreseeable future, we believe a significant number of surgeons will continue to choose to perform autograft procedures when feasible, despite the necessity of performing a second operation. In addition, many members of the medical community will continue to prefer to use metals and synthetics due in part to their familiarity with the products and the procedures required for their use. While synthetics are not osteoinductive, we believe that researchers will eventually develop methods for permitting the combination of synthetic tissue with recombinant growth stimulating materials in order to create an

43

osteoinductive synthetic tissue. We and a number of other companies are conducting research intended to develop this technology.

In the spinal market, we compete against other companies that produce and distribute allografts that promote spinal fusion. Spinal fusion products can be metal-based fusion cages or allograft implants. Our principal metals-based competitors include SpineTech, Surgical Dynamics, Medtronic Sofamor Danek and Acromed, a division of Johnson & Johnson. Our principal allograft-based competitors include Synthes, DePuy Orthopaedics, a division of Johnson & Johnson, and Osteotech.

In the sports medicine market, we compete against companies in the anchor and screw segment of the market and against companies in the allograft implant segment of the market. In the anchor and screw segment, our principal competitors include Mitek Products, a division of Johnson & Johnson, Arthrex, Acufex, a division of Smith & Nephew Endoscopy and Linvatec, a division of Conmed. In the allograft implant segment, our principal competitors include CryoLife and the Musculoskeletal Tissue Foundation.

Our bone pastes compete against human tissue-derived and synthetic bone fillers. In the human tissue-derived bone paste market, our principal competitors include Osteotech, Gen-Sci Regeneration Sciences and Wright Medical Technology. In the synthetic-derived bone filler market, we principally compete against Interpore International and Wright Medical Technology.

In the oral-maxillofacial market, we compete principally against companies that provide human-derived bone paste or synthetic bone fillers, and against companies that make periodontal membranes. Among our competitors producing human tissue derived oral-maxillofacial bone paste include Osteotech and Gen-Sci Regeneration Sciences. Among our competitors producing synthetic bone pastes include Geistlich Pharma AG and Interpore International. Competitors producing periodontal membranes include Gore Medical Products, a division of W.L. Gore & Associates, Geistlich Pharma AG and LifeCell.

Our principal competitors in the conventional allograft market include the Musculoskeletal Tissue Foundation, the American Red Cross Tissue Services, Allosource and LifeNet. Among the companies that market devices used for soft tissue anchoring in bladder neck suspensions are Mentor, Ethicon, a division of Johnson & Johnson, Boston Scientific, Smith & Nephew and C.R. Bard.

In the heart valve market we face competition from non-profit tissue banks that cryopreserve and distribute human tissue, as well as from companies that market mechanical, porcine and bovine heart valves for implantation. St. Jude Medical is the leading supplier of mechanical heart valves and has a marketing and distribution arrangement with a tissue bank that supplies them with cryopreserved human heart valves. Edwards Lifesciences, until recently a division of Baxter International, is the leading supplier of porcine heart valves. CryoLife is the leading supplier of cryopreserved human heart valves and at least two other tissue banks offer cryopreserved human heart valves, including the American Red Cross Tissue Services.

GOVERNMENT REGULATION

Government regulation plays a significant role in the processing and distribution of our current and proposed allografts. The production, testing, labeling, storage, record keeping, approval, advertising and promotion of these allografts are governed or influenced by the Food, Drug, and Cosmetic Act, the Public Health Service Act, and other federal and state statutes and regulations. Failure to comply with applicable requirements could result in fines, injunctions, civil penalties, recall or seizure of products, suspension of production, inability to market current products, criminal prosecution, and refusal of the government to authorize the marketing of new products.

We currently market allografts that are subject to the FDA's "Human Tissue Intended for Transplantation" regulation. Under the regulation, we are required to perform donor screening and

44

infectious disease testing and to document this screening and testing for each tissue we process. The FDA has authority under the rule to inspect human tissue processing facilities, and to detain, recall, or destroy tissues for which appropriate documentation is not available. We are not required to obtain premarket clearance from the FDA for products that meet the regulation's definition of "human tissue."

Some human tissues, such as heart valve allografts, corneal lenticules, and dura mater, are regulated by the FDA as medical devices. However, the FDA permits entities that processed and distributed heart valve allografts before June 26, 1991 to continue distributing heart valve allografts without obtaining 510(k) clearance or pre-market approval from the FDA. Our heart valve allografts are covered by this "grandfather" policy. It is likely that in the future the FDA will regulate additional allografts as medical devices. For allografts regulated as medical devices, we will need to obtain premarket clearance or approval through either the 510(k) premarket notification process, or the FDA's premarket approval, or PMA, process. Under the 510(k) premarket notification process, we would submit an application containing data which demonstrate the "substantial equivalence" of our product to a device marketed prior to the enactment of the Medical Device Amendments of 1976 or to a device legally marketed after that statute's enactment. The FDA may request submission of clinical information in support of the 510(k). The collection of data and preparation of a 510(k) application can be costly and time consuming.

The FDA sometimes rejects 510(k) notices or sometimes the use of a 510(k) notice may not be appropriate, requiring use of the PMA process. In addition, if a medical device is not substantially equivalent to a pre-1976 device, use of the PMA process is required. The PMA process is more complex, costly and time consuming than the 501(k) clearance procedure. To obtain premarket approval, we would be required to submit extensive preclinical and clinical data to the FDA. Upon completion and analysis of clinical studies, we then would be required to assemble and submit a PMA describing the preclinical, clinical, manufacturing and other data. Typically, the FDA also inspects the manufacturing facility for compliance with good manufacturing practice regulations. Review and approval of a PMA can take several years and some PMAs are never approved.

If clinical trials are to be conducted, we may be required to obtain FDA approval of an investigational device exemption application, or IDE. An IDE typically contains data from laboratory and animal testing and a description of the proposed study methods and clinical protocol. We must conduct our clinical studies according to a written protocol under the oversight of an institutional review board at each site where the study will be conducted, and our investigators must adhere to good clinical practices.

Some human tissue-based products, such as cellular therapies, are regulated by the FDA as biologics. While we do not at present market any allografts regulated as biologics, we may do so in the future. Before a biologic may be marketed, the FDA must approve a biologics license application, or BLA. An applicant must support a BLA with extensive data, including the results of preclinical and clinical testing which demonstrate that the product meets prescribed safety and efficacy standards. Before conducting required clinical testing with a biologic, we would be required to submit an investigational new drug application to the FDA. We would be required to conduct all clinical studies in accordance with an FDA approved protocol, subject to oversight by one or more institutional review boards. Clinical studies such as these may take several years and the FDA or sponsor may temporarily or permanently suspend a clinical study at any time. Upon completion and analysis of clinical trials, we would be required to submit a BLA containing the results of our clinical trials and other information, including a complete description of the manufacturing and control procedures. FDA review and approval of a BLA can take several years.

Products marketed under the approvals and clearances described above are subject to pervasive and continuing regulation by the FDA. To the extent our allografts are regulated by the FDA, we

45

would be required to register as a manufacturer and to manufacture these allografts in registered facilities and in accordance with good manufacturing practices. We would also be subject to post-marketing surveillance and reporting requirements. In addition, our manufacturing facilities and processes would be subject to periodic FDA inspection. Our labeling and promotional activities would be subject to scrutiny by the FDA and, in certain instances, by the Federal Trade Commission. The export of devices and biologics is also subject to regulation.

Our tissue processing generates by-products classified as medical hazardous waste by the U.S. Environmental Protection Agency and the Florida Department of Environmental Protection. We segregate the material and properly dispose of it in compliance with applicable environmental regulations.

We also are licensed by the states of New York, Florida, California and Maryland. These states are concerned primarily with ensuring proper donor screening, including screening for HIV and viral hepatitis. Although the state of New York also regulates the processing of tissue. We received a waiver from certain New York requirements after presenting information about the use of our BioCleanse system with pooled donor tissues.

EMPLOYEES

As of March 31, 2000, we had a total of 314 employees. The following chart shows the number of our employees involved in the various aspects of our business:

FACILITIES

Our physical facilities, located in Alachua, Florida include two company-owned buildings comprising 45,000 square feet, as well as leased space in buildings on adjoining and nearby property. These facilities include 20 clean-rooms for tissue processing and packaging, freezers for storage of tissue and biomedical laboratory facilities. We currently house our BioCleanse processing and biomedical laboratory operations in approximately 18,000 square feet of space which we currently lease for approximately $18,000 per month. This lease expires in February 2002. We sublease 3,855 square feet of space in our company owned buildings to the University of Florida Tissue Bank for approximately $5,000 per month, on a month to month basis. We also lease 8,800 square feet of warehouse space at a rate of $4,500 per month under a lease expiring in June 2002. We have the option to extend this lease for an additional year. Our wholly-owned subsidiary, Georgia Tissue Bank, operates from a leased building in Atlanta, Georgia comprising 9,300 square feet, with three clean- rooms for tissue processing and packaging, and freezers for tissue storage. This lease has a three year term, expiring in October 2002. The current base rent under this lease is $12,365 per month.

We plan to construct and equip a new 110,000 square foot facility on approximately 21 acres of recently acquired property adjacent to our existing facilities. We intend for this new facility to meet the FDA's "common good manufacturing practices" requirements. We believe the new facility will increase our capacity for tissue processing while allowing us to process tissue more economically. We also believe this new facility will allow us to be designated as an FDA approved medical device manufacturer. We expect to begin construction of this new facility during the third quarter of 2000.

LEGAL PROCEEDINGS

EXACTECH LITIGATION

On June 22, 1999, Exactech, Inc. filed a complaint against us, the University of Florida Tissue Bank and 19 of our medical distributors and sales agents. The complaint alleges that we have been marketing and distributing bone paste in violation of an agreement between the University of Florida Tissue Bank and Exactech. This agreement was assigned to us by the University of Florida Tissue Bank as part of our separation from that entity. The court granted our motion to enforce an arbitration provision in the agreement, and the matter is now in arbitration. Only we, Exactech and the University of Florida Tissue Bank remain as parties in the arbitration. None of our distributors are involved in the arbitration. The arbitration is presently proceeding through discovery. We believe that, even if this arbitration results in an outcome unfavorable to us, it would not have a material adverse effect on our business, financial condition or results of operations.

OSTEOTECH LITIGATION

On February 25, 1999, we, the University of Florida Tissue Bank and Medtronic Sofamor Danek filed a complaint in U.S. District Court against Osteotech, Inc. Our complaint alleges that Osteotech is infringing upon our patents for our Diaphysical Cortical Dowel. We are seeking injunctive relief and monetary damages. Discovery in this matter is ongoing and a trial date has not yet been set. Our legal expenses in this action are being reimbursed to us by Medtronic Sofamor Danek.

From time to time, we are party to various legal proceedings incident to operating a company of our size which we do not deem to be material to our financial conditions or the operation of our business.

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY

Our Certificate of Incorporation includes a provision that eliminates the personal liability of our directors for monetary damages for breach of fiduciary duty as a director, except for liability:

- for any breach of the director's duty of loyalty to us or our stockholders;

- for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

- under Section 174 of the Delaware General Corporation Law regarding unlawful dividends and stock purchases; and

- for any transaction from which the director derived an improper personal benefit.

Our Certificate of Incorporation also provides that:

- we must indemnify our directors, officers, other employees and agents to the fullest extent permitted by the Delaware General Corporation Law, subject to certain very limited exceptions; and

- we must pay expenses of our directors, and may pay expenses of our officers, other employees, agents or trustees, incurred in their capacity as a directors, officer, employees, agent or trustee in connection with a legal proceeding before the final disposition of such proceeding.

These provisions are permitted under the Delaware General Corporation Law. In addition, our Bylaws provide that we must indemnify our directors and officers to the fullest extent permitted by the Delaware General Corporation Law.

We intend to enter into indemnification agreements with each of our directors and executive officers in order to give them additional contractual rights regarding the scope of our indemnification obligations and to provide additional procedural protections. In addition, we maintain directors' and officers' insurance providing indemnification for our directors, officers and management employees for liabilities arising as a result of their employment with us. We believe that these indemnification provisions and agreements are necessary to attract and retain qualified directors and officers.

The limitation of liability and indemnification provisions in our Certificate of Incorporation and Bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against directors and officers,

54

even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder's investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers under indemnification provisions.

Except as otherwise described in this prospectus, there is at present no pending litigation or proceeding involving any of our directors, officers, or employees regarding which indemnification is sought, nor are we aware of any threatened litigation that may result in claims for indemnification.

OMNIBUS STOCK OPTION PLAN

In July 1998, our board of directors and stockholders adopted the Regeneration Technologies, Inc. Omnibus Stock Option Plan. A maximum of shares have been authorized for issuance pursuant to the plan. Through December 31, 1999, we issued options to purchase shares of our common stock to our directors, officers, employees and various third parties who provide services to us. Of these options, currently are exercisable. The exercise prices of the options granted under the Omnibus Stock Option Plan range from $ to $ . The exercise price for each option grant was set at the fair market value of the shares of our common stock on the date of grant, as determined by our board of directors. The purposes of the plan are to promote our long-term growth and profitability by providing key personal with incentives to improve stockholder value and to enable us to attract, retain and reward skilled employees. There are an additional shares of common stock available for issuance under the plan.

The plan allows for the discretionary grant of restricted stock, non-qualified stock options, incentive stock options as defined in Section 422 of the Internal Revenue Code of 1986 and other stock-based awards. Any award of an incentive stock option is limited to our employees and the employees of our subsidiaries. The exercise price per share may not be less than 100% of the fair market value of such shares on the date the option is granted.

The plan is administered by our board of directors or any committee it may designate for this purpose. The board makes the determinations with respect to awards under the plan, including which eligible individuals are to receive awards under the plan and the specific terms, vesting conditions, if any, and number of shares of stock to which each award related. Additionally, the board may grant awards with different terms and conditions and also may accelerate the vesting of outstanding awards and options at any time. At the time the options are granted, the board will set the price at which options can be exercised.

Option holders do not and will not have any rights as stockholders until they have exercised their options. The number of shares of our common stock covered by awards will be adjusted in the event of any stock split, merger, recapitalization or similar corporate event. This plan has a term of ten years, expiring in July 2009.

YEAR 2000 INCENTIVE COMPENSATION PLAN

In January 2000, our board of directors and stockholders adopted the Regeneration Technologies, Inc. Year 2000 Incentive Compensation Plan. A maximum of shares have been authorized for issuance pursuant to the plan. The board administers the Incentive Compensation Plan and grants discretionary awards to eligible participants pursuant to each program's specific goals and targets. The plan allows for the discretionary grant of restricted stock, non-qualified stock options, incentive stock options as defined in Section 422 of the Internal Revenue Code of 1986 and other stock-based awards. The program has a term of 10 years, expiring in January 2010.

RELATED PARTY TRANSACTIONS

LEGAL RELATIONSHIPS WITH THE UNIVERSITY OF FLORIDA TISSUE BANK

SEPARATION FROM UFTB

We began operations on February 12, 1998 when the University of Florida Tissue Bank or UFTB, contributed to us its allograft manufacturing and processing operations, related equipment and technologies, distribution arrangements, research and development activities and certain other assets. We also assumed certain liabilities of UFTB that were related to the transferred business. Various agreements relating to the transferred business to which UFTB was a party also were assigned to us at that time, including one of our two current management services agreements with Medtronic Sofamor Danek. At approximately the same time, we sold shares of our preferred stock to a number of unrelated investors and issued additional shares of our preferred stock to UFTB in exchange for the assets it contributed to us. Immediately prior to this offering, UFTB beneficially owned approximately 16% of our outstanding voting equity securities. Dr. Peter F. Gearen, one of our directors, presently is an Associate Professor at the University of Florida, which controls UFTB.

At approximately the same time as our separation from UFTB, James M. Grooms, our Chief Executive Officer, President and Chairman who served as an officer of UFTB prior to our separation, contributed his royalty rights in certain intellectual property to us in exchange for shares of our preferred stock. We recorded the assets acquired from UFTB and Mr. Grooms and the liabilities assumed from UFTB at their historical cost basis since these were deemed to be transactions between entities under common control.

UFTB is our largest tissue supply source. The tax-exempt status of UFTB requires our relationship with UFTB to be conducted at arm's length. For this reason, our relationship with UFTB is pursuant to a Tissue Recovery Agreement which is designed to provide for arm's-length charges for services between the two companies. Under the agreement, UFTB supplies certain of its tissues exclusively to us. Additionally, we have a right of first refusal on other tissues which UFTB is not currently providing to us. We pay UFTB recovery fees as reimbursement for expenses it incurs in tissue recovery procedures. The amount of the recovery fee depends upon the type and amount of tissue recovered. We incurred charges of approximately $2.4 million during 1998 and $5.3 million during 1999 under this agreement. This agreement expires in April 2009.

We have an employment agreement with Nancy R. Holland, our Vice President of Donor Services under which she is required to devote 50% of her working time to our business. Ms. Holland also serves as the Chief Executive Officer and a director of the University of Florida Tissue Bank, Inc. Ms. Holland recuses herself from decisions by UFTB's board of directors with respect to UFTB's relationship with us.

ASSUMPTION OF CONVENTIONAL ALLOGRAFT DISTRIBUTION BUSINESS OF UFTB

On April 15, 1999, we entered into a Programs Transfer Agreement with UFTB under which UFTB transferred to us its tissue recovery operations outside of Florida and Georgia, conventional allograft distribution services, allograft inventory, certain equipment and fixtures and its interest in various tissue recovery agreements. UFTB transferred its unprocessed donor tissue and conventional allograft implants with an assumed fair value of approximately $3.0 million, and certain equipment and fixtures with an assumed fair value of approximately $0.1 million as an offset against amounts owed to us by UFTB at the time we assumed this business. Additionally, UFTB agreed to repay the remaining balance of amounts it owed to us at that time by offsetting recovery fees from April 15, 1999 through June 30, 1999 against the outstanding balance, which fees were approximately $0.8 million, and by making monthly payments during the remainder of 1999 totaling approximately $1.2 million. Prior to

56

this transfer to us of UFTB's tissue recovery operations, we charged UFTB approximately $3.5 million during 1998 and approximately $2.6 million during 1999 for tissue processing services.

We also share facilities, overhead and various personnel with UFTB, the terms of which we believe are at least as favorable as those we would obtain in an arms-length relationship.

LEGAL RELATIONSHIP WITH MEDTRONIC SOFAMOR DANEK

The two management services agreements between us and Medtronic Sofamor Danek grant to that company exclusive worldwide rights to manage the distribution of our bone pastes for spinal uses and our current line of spinal allografts, including our MD-Series threaded and non-threaded dowels, tapered dowels and other spinal allografts. We pay to Medtronic Sofamor Danek management services fees as a percentage of the amount charged to customers for the allografts we distribute into these markets. We incurred charges under these agreements aggregating approximately $24.1 million during 1998 and approximately $40.0 million during 1999. These agreements terminate in May 2018 and July 2021. During 1999, Medtronic Sofamor Danek purchased shares of our preferred stock for an aggregate purchase price of $5.0 million. Upon the closing of this offering, these shares will represent approximately % of our outstanding voting equity securities. E. Ronald Pickard, one of our directors, is President of Medtronic Spinal and Neurological Group, a division of Medtronic Sofamor Danek. Prior to the merger of Sofamor Danek Group and Medtronics, Mr. Pickard served in various executive capacities at Sofamor Danek Group, including as Chairman of the Board and Chief Executive Officer.

DESCRIPTION OF CAPITAL STOCK

Effective as of the closing of this offering, our authorized capital stock will consist of 50,000,000 shares of common stock, $.001 par value, and 5,000,000 shares of preferred stock, $.001 par value.

COMMON STOCK

As of December 31, 1999, shares of our common stock were outstanding and held of record by stockholders after giving effect to the conversion of all outstanding shares of our then-outstanding shares of preferred stock upon the closing of this offering. Following the issuance of the shares of our common stock offered hereby, there will be shares of common stock outstanding and no shares of preferred stock upon the closing of this offering, assuming no exercise of the underwriter's over-allotment option.

Subject to preferences that may be applicable to any preferred stock outstanding at the time, the holders of outstanding shares of common stock are entitled to receive dividends out of assets legally available therefor at such times and in such amounts as the board of directors from time to time may determine. Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. Cumulative voting for the election of directors is not authorized by our certificate of incorporation, which means that the holders of a majority of the shares voted can elect all of the directors then standing for election. Holders of our common stock are not entitled to preemptive rights and our common stock is not subject to conversion or redemption. Upon our liquidation, dissolution or winding-up, the assets legally available for distribution to stockholders shall be distributed ratably among the holders of our common stock after payment of liquidation preferences, if any, on any outstanding shares of preferred stock and payment of other claims of creditors.

There is currently no active trading market for our common stock. We will file an application to have our common stock approved for quotation on the Nasdaq National Market under the symbol "RTIX."

PREFERRED STOCK

Upon the closing of this offering, we will not have any shares of preferred stock outstanding. Our 5,000,000 authorized shares of preferred stock may by issued in one or more series without further stockholder authorization, and our board of directors is authorized to fix and determine the terms, limitations and relative rights and preferences of the preferred stock, to establish series of preferred stock and to fix and determine the variations between these series. If we issue preferred stock, it would have priority over our common stock with respect to dividends and to other distributions, including the distribution of assets upon liquidation, and we may be obligated to repurchase or redeem our preferred stock. Our board of directors can issue preferred stock without the approval of our common stockholders. Any preferred stock we issue may have voting and conversion rights which could adversely affect the rights of holders of our common stock. In addition to having a preference with respect to dividends or liquidation proceeds, if preferred stock is issued, it may be entitled to the allocation of capital gains from the sale of our assets. We do not have any present plans to issue any shares of preferred stock.

WARRANTS

As of December 31, 1999 we had outstanding warrants to purchase an aggregate of shares of our common stock at a weighted average exercise price of $ .

59

REGISTRATION RIGHTS

Under the terms of an agreement between us and certain of our stockholders, these stockholders are entitled to certain rights with respect to the registration of these shares under the Securities Act of 1933 commencing 180 days after the consummation of this offering. If we receive from the required number of holders of these shares a written request to effect a registration with respect to all or a part of their shares, we must use our best efforts to effect a registration, provided the offering price for these shares in the aggregate is at least $5,000,000. We are obligated to effect only two of these registrations.

When we are eligible to use a registration statement on Form S-3, our stockholders may request that we file a registration statement on Form S-3 covering all or a portion of their shares, provided that the aggregate public offering price is at least $500,000.

In addition, these and certain of our other stockholders have "piggyback" registration rights. If we propose to register any common stock under the Securities Act, other than pursuant to the registration rights described above, these stockholders may require us to include all or a portion of their securities in that registration.

We would bear all registration expenses incurred in connection with any of the above registrations. Each of these stockholders participating in any registration would pay their own underwriting discounts, selling commission and stock transfer taxes applicable to the sale of their securities.

STOCKHOLDERS' AGREEMENT

We have entered into a stockholders' agreement with our current stockholders. The stockholders have agreed to vote their shares of our voting capital stock so as to cause the board of directors to consist of seven persons, five of which are to be approved by holders of our preferred stock outstanding prior to this offering. This agreement terminates upon the closing of this offering.

DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER PROVISIONS

Under Section 203, certain "business combinations" between a Delaware corporation with shares that generally are publicly traded or held of record by more than 2,000 stockholders, and an "interested stockholder" are prohibited for a three-year period following the date that such stockholder became an interested stockholder, unless:

- the corporation has elected in its certificate of incorporation or bylaws not to be governed by the Delaware anti-takeover law;

- the business combination was approved by the board of directors of the corporation before the other party to the business combination became an interested stockholder;

- upon consummation of the transaction that made it an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the commencement of the transaction, excluding voting stock owned by directors who are also officers or held in employee stock plans in which the employees do not have a right to determine confidentially whether to tender or vote stock held by the plan; or

- the business combination was approved by the board of directors of the corporation and ratified by 66 2/3% of the voting stock which the interested stockholder did not own. The three-year prohibition does not apply to certain business combinations proposed by an interested stockholder following the announcement or notification of certain extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation's directors. The term "business combination" is defined generally to include

60

mergers or consolidations between a Delaware corporation and an interested stockholder, transactions with an interested stockholder involving the assets or stock of the corporation or its majority-owned subsidiaries and transactions which increase an interested stockholder's percentage ownership of stock. The term "interested stockholder" is defined generally as a stockholder who becomes beneficial owner of 15% or more of a Delaware corporation's voting stock. We have not elected in our certificate of incorporation or bylaws not to be governed by the Delaware anti-takeover law. Section 203 could have the effect of delaying, deferring or preventing a change in control of Regeneration Technologies.

Our certificate of incorporation provides for the division of our board of directors into three classes, as nearly equal in size as possible, with each class beginning its three-year term in different years. Any director may be removed only for cause by the vote of a majority of the shares entitled to vote for the election of directors.

In addition, provisions of our certificate of incorporation and bylaws summarized in the following paragraphs may have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders.

STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS

Our bylaws provide that our stockholders may not take action by written consent, but only at an annual or special meeting of stockholders. Our bylaws further provide that special meetings of our stockholders may be called only by the chairman of our board of directors or a majority of our board of directors.

SUPERMAJORITY VOTING PROVISIONS

Our certificate of incorporation provides that the affirmative vote of at least 66 2/3% of our stockholders is required to amend the provisions of our certificate of incorporation and bylaws relating to the election of our board of directors, stockholder action by written consent and the calling of special meetings.

AUTHORIZED BUT UNISSUED SHARES

The authorized but unissued shares of our common stock and preferred stock are available for future issuance without stockholder approval. These additional shares may be used for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued common stock and preferred stock could render more difficult or discourage an attempt to obtain control of our company by means of a proxy contest, tender offer, merger or otherwise.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

We will enter into indemnification agreements with our current directors and executive officers. These agreements may have the practical effect in some cases of eliminating our stockholders' ability to collect monetary damages from our directors. We believe that these contractual agreements and the provisions in our certificate of incorporation and bylaws are necessary to attract and retain qualified persons as directors and officers.

TRANSFER AGENT AND REGISTRAR

The transfer agent and registrar for our common stock is .

SHARES ELIGIBLE FOR FUTURE SALE

Prior to the offering, there has been no public market for our common stock, and we cannot predict the effect, if any, that market sales of shares or the availability of any shares for sale will have on the market price of the common stock prevailing from time to time. Sales of substantial amounts of common stock, or the perception that such sales could occur, could adversely affect the market price of our common stock and our ability to raise capital through a sale of our securities.

Upon completion of this offering, we will have shares of common stock outstanding (or shares if the underwriters over-allotment option is exercised in full) of which will be "restricted shares." This leaves shares eligible for sale in the public market as follows:

NUMBER OF SHARES                                                 DATE
----------------             ----------------------------------------------------------------------------
      .....................  After 90 days from the date of this prospectus

      .....................  After 180 days from the date of this prospectus (subject, in some cases, to
                             volume limitations)

      .....................  After various times after 180 days from the date of this prospectus

The shares (or up to shares if the underwriters' over-allotment option is exercised in full) of common stock sold in this offering will be freely tradable without further restriction or further registration under the Securities Act, except for shares purchased by an affiliate (as this term is defined in the Securities Act) of ours, which will be subject to the limitations of Rule 144 under the Securities Act. Subject to certain contractual limitations, holders of restricted shares generally will be entitled to sell these shares in the public securities market without registration either pursuant to Rule 144 or any other applicable exemption under the Securities Act.

In general, under Rule 144 under the Securities Act, a person (or persons whose shares are aggregated) who has beneficially owned restricted securities within the meaning of Rule 144 for at least one year, and including the holding period of any prior owner except an affiliate, would be entitled to sell within any three-month period a number of shares that does not exceed the greater of one percent of the then outstanding shares of our common stock or the average weekly trading volume of our common stock on the Nasdaq National Market during the four calendar weeks preceding such sale. Sales under Rule 144 are also subject to certain manner of sale provisions, notice requirements and the availability of current public information about Regeneration Technologies. Any person (or persons whose shares are aggregated) who is not deemed to have been our affiliate at any time during the three months preceding a sale, and who has beneficially owned shares for at least two years (including any period of ownership of preceding non-affiliated holders), would be entitled to sell such shares under Rule 144(k) without regard to the volume limitations, manner of sale provisions, public information requirements or notice requirements. An "affiliate" is a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or under common control with, an issuer.

Within approximately 180 days after the date of this prospectus, we intend to file one or more registration statements on Form S-8 under the Securities Act to register shares of common stock subject to outstanding stock options or reserved for issuance under our equity compensation plans. Upon completion of this offering, options to purchase approximately shares will be outstanding under our equity compensation plans.

Our directors and officers and some of our stockholders who hold shares in the aggregate (including options and warrants to purchase common stock) have entered into lock-up agreements pursuant to which they have agreed that they will not sell other than in connection with this offering, directly or indirectly, any shares of common stock without the prior written consent of Banc of America

62

Securities LLC for a period of 180 days from the date of this prospectus; provided, however, they may gift or transfer shares so long as the donee or transferee agrees to be bound by the terms of the lock-up agreement.

Under the terms of an agreement between us and the holders of shares of our preferred stock, the preferred stockholders are entitled to certain rights with respect to the registration of these Shares under the Securities Act commencing 180 days after the consummation of this offering. If we receive from the holders of at least 40% of any class of preferred stock a written request to effect a registration with respect to all or a part of their shares, we must use our best efforts to effect such a registration, provided the shares owned by the requesting stockholders cover at least 33% of the then outstanding class of security of the offering price in the aggregate is at least $5,000,000. We are only obligated to effect two of these registrations.

When we are eligible to utilize a registration statement on Form S-3 to register an offering of our securities, these stockholders may request that we file a registration statement on Form S-3 covering all or a portion of their shares, provided that the aggregate public offering price is at least $500,000.

In addition, certain of our stockholders have certain "piggyback" registration rights. If we propose to register any common stock under the Securities Act, other than pursuant to the registration rights above, these stockholders may require us to include all or a portion of their securities in such registration. We are obligated to use our best efforts to effect this registration.

The underwriters initially will offer shares to the public at the price specified on the cover page of this prospectus. The underwriters may allow to some dealers a concession of not more than $ per share. The underwriters also may allow, and any dealers may reallow, a concession of not more than $ per share to some other dealers. If all the shares are not sold at the initial public offering price, the underwriters may change the offering price and the other selling terms. The common stock is offered subject to a number of conditions, including:

- receipt and acceptance of our common stock by the underwriters; and

- the right to reject orders in whole or in part.

The underwriters have an option to buy up to additional shares of common stock from Regeneration Technologies to cover sales of shares by the underwriters which exceed the number of shares specified in the table above, and will be sold by Regeneration Technologies in the event that the option is not exercised in full. The underwriters have 30 days to exercise this option. If the underwriters exercise this option, they will each purchase additional shares approximately in proportion to the amounts specified in the table above. Regeneration Technologies will pay the expenses associated with the exercise of the overallotment option.

The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters assuming both no exercise and full exercise of the underwriters' option to purchase additional shares.

Regeneration Technologies and substantially all holders of its stock prior to this offering, as well as substantially all holders of stock options and warrants, have entered into lock-up agreements with the underwriters. Under those agreements, Regeneration Technologies and those holders of stock, options and warrants may not dispose of or hedge any Regeneration Technologies common stock or securities convertible into or exchangeable for shares of Regeneration Technologies common stock unless permitted to do so by Banc of America Securities LLC. These restrictions will be in effect for a period of 180 days after the date of this prospectus. At any time and without notice, Banc of America Securities LLC may, in its sole discretion, release all or some of the securities from these lock-up agreements.

Regeneration Technologies and the selling stockholder will indemnify the underwriters against liabilities, including liabilities under the Securities Act. If Regeneration Technologies and the selling stockholder are unable to provide this indemnification, they will contribute to payments the underwriters may be required to make in respect of those liabilities.

In connection with this offering, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include:

- short sales;

- stabilizing transactions; and

- purchases to cover positions created by short sales.

Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in this offering. Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress.

The underwriters may also impose a penalty bid. This means that if the representatives purchase shares in the open market in stabilizing transactions or to cover short sales, the representatives can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

The underwriters may engage in activities that stabilize, maintain or otherwise affect the price of the common stock, including:

- over-allotment;

- stabilization;

- syndicate covering transactions; and

- imposition of penalty bids.

As a result of these activities, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the Nasdaq National Market, in the over-the-counter-market or otherwise.

The underwriters do not expect sales to discretionary accounts to exceed 5% of the total number of shares of common stock offered by this prospectus.

Prior to this offering, there has been no public market for the common stock of Regeneration Technologies. The initial public offering price will be negotiated between Regeneration Technologies and the underwriters. Among the factors to be considered in such negotiations are:

- the history of, and prospects for, Regeneration Technologies and the industry in which it competes;

65

- the past and present financial performance of Regeneration Technologies;

- an assessment of Regeneration Technologies' management;

- the present state of Regeneration Technologies' development;

- the prospects for future earnings of Regeneration Technologies;

- the prevailing market conditions of the applicable United States securities market at the time of this offering;

- market valuations of publicly traded companies that Regeneration Technologies and the representatives believe to be comparable to Regeneration Technologies; and

- other factors deemed relevant.

An affiliate of Banc of America Securities LLC is the lender under our $6.0 million revolving line of credit facility and our $2.8 million 20-year mortgage, and also provides to us services related to treasury management, derivative transactions and institutional investments. In addition, affiliates of Lehman Brothers Inc. and Stephens Inc., representatives of the underwriters, beneficially own approximately and shares of our common stock, respectively.

The underwriters, at our request, have reserved for sale to our employees, affiliates and strategic partners at the initial public offering price up to five percent of the shares being offered by this prospectus. The sale of shares to our employees, affiliates and strategic partners will be made by Banc of America Securities LLC. We do not know if our employees, affiliates or strategic partners will choose to purchase all or any portion of these reserved shares, but any purchases they do make will reduce the number of shares available to the general public. If all of these reserved shares are not purchased, the underwriters will offer the remainder to the general public on the same terms as the other shares offered by this prospectus.

Fulbright & Jaworski L.L.P., New York, New York will pass on the validity of the common stock offered by this prospectus for us. Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., Boston, Massachusetts, will pass upon certain legal matters in connection with this offering for the underwriters.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors of Regeneration Technologies, Inc.:

We have audited the accompanying consolidated balance sheets of Regeneration Technologies, Inc. and subsidiary (the "Company") as of December 31, 1998 and 1999, and the related consolidated statements of operations, stockholders' (deficiency) equity and cash flows for the period from February 12, 1998 (date operations began) to December 31, 1998 and for the year ended December 31, 1999. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

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

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 1998 and 1999, and the results of its operations and its cash flows for the period from February 12, 1998 (date operations began) to December 31, 1998 and for the year ended December 31, 1999 in conformity with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

PERIOD FROM FEBRUARY 12, 1998 (DATE OPERATIONS BEGAN) TO DECEMBER 31, 1998
AND THE YEAR ENDED DECEMBER 31, 1999

1. ORGANIZATION

Regeneration Technologies, Inc. ("RTI"), was incorporated in Florida on August 22, 1997, and began operations on February 12, 1998, following a contribution of assets to RTI by the University of Florida Tissue Bank, Inc. ("UFTB"). At the time of the separation, UFTB contributed certain assets (including certain intellectual property) to RTI and RTI assumed certain related liabilities in exchange for 1,200,000 shares of Series A Preferred stock (see Note 10). In addition, an officer of UFTB contributed his royalty rights in certain intellectual property to RTI in exchange for 577,348 shares of Series A Preferred stock. RTI recorded the assets acquired and the liabilities assumed from UFTB and the assets acquired from the officer of UFTB at their historical cost basis as these were deemed to be transactions between entities under common control. As such, the $39,643 of net liabilities assumed is accounted for as a dividend, resulting in a charge to additional paid-in capital. The historical costs of the individual assets acquired and liabilities assumed by RTI at the date of the separation from UFTB are presented below:

Accounts receivable.........................................  $ 3,535,562
Inventories and supplies....................................    1,273,877
Prepaid expenses............................................      105,972

Simultaneous with the separation of RTI from UFTB, certain third parties invested approximately $6.6 million in exchange for 748,152 shares of Series B Preferred stock.

During 1999, RTI's wholly owned subsidiary, Georgia Tissue Bank ("GTB"), acquired the net assets of the National Tissue Bank Network, Georgia Tissue Bank, Inc. ("NTBN") along with certain equipment owned by a director of NTBN (see Note 6).

RTI and GTB (collectively, the "Company") process human musculoskeletal tissue received from various tissue recovery agencies. The processing transforms the tissue into either conventional or precision tooled allografts, some of which are patented. These allografts are distributed domestically and internationally, for use in spinal vertebrae repair, musculoskeletal reconstruction and fracture repair. The processed tissue includes cortical dowels, cervical implants, cortical bone interference screws, and bone paste grafts.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION--The consolidated financial statements include the accounts of RTI and its wholly owned subsidiary GTB (see Note 6). All material intercompany balance and transactions have been eliminated in consolidation.

CASH AND CASH EQUIVALENTS--The Company considers all funds in banks and overnight sweep accounts with an original maturity of three months or less to be cash and cash equivalents.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) PRODUCT AND SUPPLY INVENTORIES--Product and supply inventories are stated at the lower of cost or market, with cost determined by the first-in, first-out method.

PROPERTY, PLANT, AND EQUIPMENT--Property, plant, and equipment are stated at cost less accumulated depreciation and amortization. The cost of equipment under capital leases and leasehold improvements is amortized on the straight-line method over the shorter of the lease term or the estimated useful life of the asset. Depreciation is computed on the straight-line method over the following estimated useful lives of the assets:

Production equipment                                          8 to 10 years
Leasehold improvements                                        8 to 10 years
Office equipment, furniture, and fixtures                      5 to 7 years
Computer hardware and software                                      3 years

OTHER ASSETS--Other assets consist of patents and trademarks. Patents and trademarks are amortized on the straight-line method over the shorter of the remaining protection period or estimated useful life.

RESEARCH AND DEVELOPMENT COSTS--Research and development costs are expensed as incurred. Research and development costs for the periods ended December 31, 1998 and 1999 were $1,472,410 and $1,675,019, respectively.

REVENUE RECOGNITION--Revenue is recognized at the time the Company ships the processed tissue. Revenues are reported gross of any management services fees the Company incurs to distribute its products. Any other revenues directly related to the Company's core operations are recognized when all significant contractual obligations have been satisfied. A $4,500,000 nonrefundable, up-front fee received from Sofamor Danek Group in the period ended December 31, 1998 is being deferred and recognized as revenue over the 20 year life of the exclusive management services agreement with Sofamor Danek Group on a straight-line basis. This revenue is shown in the consolidated statements of operations in other revenues from core operations.

INCOME TAXES--The Company accounts for income taxes under the asset and liability approach specified by Statement of Financial Accounting Standards ("SFAS") No. 109, ACCOUNTING FOR INCOME TAXES. SFAS No. 109 requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company's consolidated financial statements or tax returns by applying enacted statutory rates applicable to future years to differences between financial statement carrying amounts and the tax basis of existing assets and liabilities.

STOCK-BASED COMPENSATION PLANS--In October 1995, the Financial Accounting Standards Board issued SFAS No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION, which is effective for fiscal years beginning after December 15, 1995. Under SFAS No. 123, the Company may elect to recognize stock-based compensation expense based on the fair value of the awards or to account for stock-based compensation under Accounting Principles Board ("APB") Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES, and disclose in the consolidated financial statements the effects of SFAS No. 123 as if the recognition provisions were adopted. The Company has adopted the recognition provisions of APB Opinion No. 25.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) EARNINGS PER SHARE--Basic earnings per share ("EPS") is computed by dividing earnings available to common shareholders by the weighted average number of common shares outstanding for the periods. Diluted EPS reflects the potential dilution of securities that could share in the earnings. A reconciliation of the number of common shares used in calculation of basic and diluted EPS is presented below:

                                                 PERIOD FROM
                                             FEBRUARY 12, 1998 TO      YEAR ENDED
                                              DECEMBER 31, 1998     DECEMBER 31, 1999
                                             --------------------   -----------------
Basic EPS..................................        770,702                770,702
Effect of dilutive securities:
  Stock options............................             --                130,103
  Conversion of preferred stock............             --              2,602,354
                                                   -------              ---------
Diluted EPS................................        770,702              3,503,159
                                                   =======              =========

The conversion of preferred stock to common stock was not included in the computation of diluted EPS for the period ended December 31, 1998 as the inclusion would be antidilutive. Options to purchase approximately 65,000 shares of common stock at $27.10 per share were outstanding as of December 31, 1999 but were not included in the computation of diluted EPS for the year ended December 31, 1999 because the options' exercise price was greater than the average market price of the common shares.

USE OF ESTIMATES--The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

IMPAIRMENT OF LONG-LIVED ASSETS--Periodically, the Company evaluates the recoverability of the net carrying value of its property, plant and equipment and its intangible assets by comparing the carrying values to the estimated future undiscounted cash flows. A deficiency in these cash flows relative to the carrying amounts is an indication of the need for a write-down due to impairment. The impairment write-down would be the difference between the carrying amounts and the fair value of these assets. A loss on impairment would be recognized by a charge to earnings.

FAIR VALUE OF FINANCIAL INSTRUMENTS--The estimated fair value of amounts reported in the consolidated financial statements has been determined by using available market information and appropriate valuation methodologies. The carrying value of all current assets and current liabilities approximates fair value because of their short-term nature. The fair value of capital lease obligations approximates the carrying value, based on current market prices.

NEW ACCOUNTING STANDARDS--The Financial Accounting Standards Board recently issued SFAS No. 137, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES--DEFERRAL OF EFFECTIVE DATE OF FASB STATEMENT NO. 133 ("SFAS No. 137"). SFAS No. 137 defers for one year the effective date of SFAS No. 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES ("SFAS No. 133"). The rule now will apply to all fiscal quarters of all fiscal years beginning after June 15, 2000. SFAS No. 137 permits early adoption as of the beginning of any fiscal quarter after its issuance. SFAS No. 133 will require the Company to recognize all derivatives on the balance sheet at fair value. Derivatives that are not hedges

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) must be adjusted to fair value through income. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives will either be offset against the change in fair value of the hedged assets, liabilities, of firm commitments through earnings or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. The Company has not completed its evaluation of the impact of SFAS No. 133, if any, on the financial statements.

RECLASSIFICATION--Certain 1998 amounts have been reclassified to conform to the 1999 presentation.

6. ASSET PURCHASE

On November 1, 1999, GTB acquired the assets and existing liabilities of NTBN and certain equipment owned by Dr. Charles Garrison, a director of NTBN. The purpose of the transaction was to expand the Company's ability to produce conventional tissue grafts and expand donor recovery and tissue distribution in areas outside of the Company's existing network for donor recovery and tissue distribution.

The acquisition was recorded under the purchase method of accounting and, accordingly, the purchase price was allocated to the assets and liabilities on the basis of estimated fair market value on the date of purchase. The fair value of the assets and liabilities at the date of acquisition recorded in conjunction with the transaction is as follows:

Accounts receivable.........................................  $  358,942

The notes payable relate to the assets purchased from NTBN and are collateralized by the assets purchased. All notes are due in November 2002 (see Note 6).

The capital leases have interest rates ranging from 9.05% to 10% and are collateralized by the related equipment and are due from 2002 through 2006 (see Note 13).

8. LINE OF CREDIT

In March 1999, the Company entered into a revolving line of credit for an amount not to exceed $2,000,000 expiring in March 2000. This line of credit was subsequently replaced in September 1999 with a new line not to exceed $6,000,000 expiring in September 2000. The line of credit is to be utilized for the purpose of supporting accounts receivable, with accounts receivable also serving as the collateral for the line of credit. The interest rate associated with this line of credit is the 30-day LIBOR rate plus 150 basis points. At December 31, 1999, the interest rate of the line of credit is 7.97%.

The credit line agreement contains various restrictive covenants, which limit among other things, indebtedness, loans, acquisitions, dividends and stock purchases.

The valuation allowance for deferred tax assets was $1,534,183 and $0, respectively, for the periods ended December 31, 1998 and 1999. The net change in the total valuation allowance was a decrease of $1,534,183 for the year ended December 31, 1999. The reduction was attributable to projections of future taxable income whereby management believes it is more likely than not that the Company will recognize the benefits of the net deductible temporary differences, which generated the deferred tax asset.

9. INCOME TAXES (CONTINUED) The Company established a valuation allowance in the period ended December 31, 1998 of $1,534,183. Management determined that it was more likely than not that the deferred tax asset in excess of the amount of current taxes paid in that year would not be realized.

The effective tax rate differs from the statutory federal income tax rate for the following reasons:

                                                                1998       1999

10. STOCKHOLDERS' EQUITY

PREFERRED STOCK--Series A and B Preferred stocks are on parity with each other regarding dividends and liquidation, and are senior to the Company's common stock. Dividends, when and if declared by the Board of Directors, are cumulative and accrue at 6% of the preferred stock face value of $13,934,408 for the Series A Preferred stock (1,777,348 shares at $7.84 per share) and $6,580,000 for the Series B Preferred stock (748,152 shares at $8.80 per share). The Series A Preferred stock has been recorded at its par value rather than its face and liquidation value because the issuance of the Series A Preferred stock resulted from a transaction between entities under common control (see Note 1). The aggregate amount of cumulative Preferred dividends in arrears as of December 31, 1998 and 1999 is $1,090,453 and $2,321,317, respectively. Liquidation cannot occur unless approved by 75% of the Series A Preferred stockholders and 75% of the Series B Preferred stockholders, in which event, the Series A Preferred stockholders would receive the intellectual property rights originally contributed to the Company in exchange for the Series A Preferred shares, and the Series B Preferred stockholders would receive the $6,580,000 originally paid to the Company (see Note 1).

Series A and B Preferred stocks have voting rights equal to the number of whole shares of common stock into which the preferred stocks can be converted. Series A Preferred stock is convertible at any time into common shares at a price of $7.84 per share and Series B Preferred stock is convertible at any time into common shares at a price of $8.80 per share.

Series C Preferred stock is senior to the Series A and B Preferred stocks and common stock as to dividends and upon liquidation. Dividends, when and if declared by the Board of Directors, are cumulative and accrue at 6% of the preferred stock value of $10,000,000 (368,990 shares at $27.101 per share). The aggregate amount of cumulative preferred dividends in arrears as of December 31, 1999 is $135,000. Liquidation cannot occur unless approved by 75% of the Series C Preferred stockholders, in which event, the Series C Preferred stockholders would receive the $10,000,000 originally paid to the Company. Series C Preferred stock has voting rights equal to the number of whole shares of common

10. STOCKHOLDERS' EQUITY (CONTINUED) stock into which the preferred stock can be converted. Series C Preferred stock is convertible at any time into common shares at a price of $27.101 per share. Holders of Series C Preferred stock were issued warrants to purchase up to 46,124 shares of common stock for a period of one year from the date of issuance at a purchase price of $27.10 per share.

COMMON STOCK--The common stock's voting, dividend, and liquidation rights are subject to and qualified by the rights of the holders of the preferred stocks. Common stockholders are entitled to one vote for each share held at all stockholder meetings. Common stock is not redeemable.

STOCK OPTION PLANS--In July 1998, the Company adopted a stock option plan (the "Plan") which provides for the grant of incentive and nonqualified stock options to key employees, including officers and directors of the Company. The option price per share may not be less than 100% of the fair market value of such shares on the date such option is granted. At December 31, 1999, options to acquire up to 918,000 shares of common stock may be granted pursuant to the Plan.

Stock option activity is summarized as follows at December 31, 1998 and 1999:

Outstanding options under the Plan vest over a three- to five-year period. Options expire ten years from the date of grant. As of December 31, 1999, 32,133 options were exercisable with a weighted-average exercise price of $6.25.

The weighted average fair value of options granted during the periods ended December 31, 1998 and 1999 was $6.25 and $13.77, respectively.

Since the Company applies APB Opinion No. 25 in accounting for its stock options, no compensation cost has been recognized for the options granted to employees because the exercise price equaled the fair market value on the date of the grant. Had compensation cost been determined on the basis of fair value pursuant to SFAS No. 123, net income (loss) would have been affected as follows for the periods ended December 31, 1998 and 1999:

Dividend yield..............................................          --
Risk free interest rate.....................................      4.6%-5.92%
Option term.................................................      4.77 years

STOCK AWARDS--The Company awarded 770,702 shares of common stock to various key employees at the beginning of the Company's operations. These shares of common stock, which were valued at $0.85 per share, vest over a five-year period. At the date of issuance, $655,097 in deferred compensation was recorded by the Company. Compensation expense of approximately $119,000 and $131,000 was recognized for these stock awards for the periods ended December 31, 1998 and 1999, respectively.

11. RETIREMENT BENEFITS

The Company has a qualified 401(k) plan available to all employees who meet certain eligibility requirements. The 401(k) plan allows the employee to contribute 20% of the employee's salary up to the maximum allowed under the Internal Revenue Code. The Company has the discretion to make

11. RETIREMENT BENEFITS (CONTINUED) matching contributions up to 6% of the employee's earnings. For the periods ended December 31, 1998 and 1999, the Company's contributions to the plan were $83,846 and $156,203, respectively.

12. CONCENTRATIONS OF RISK

The Company's principal concentration of risk is related to its limited distribution channels. In 1998, nearly all of the Company's revenues are related to the distribution efforts of four independent companies, with approximately 95% of its revenues coming from one of the distribution companies. In 1999, the Company expanded to include more revenue from direct distribution. The amount of revenue from direct distribution was approximately 15% with 80% of the remaining revenue coming from one of the distribution channels.

The Company's operations are dependent on the availability of bone and related connective tissue from human donors. The Company relies on the efforts of independent procurement agencies to educate the public and increase the willingness to donate bone tissue. These procurement agencies may not be able to obtain sufficient donors to meet present or future demands.

13. COMMITMENTS AND CONTINGENCIES

MANUFACTURING RIGHTS--The Company has licensed manufacturing rights for some of its products. Under the agreement, the Company has agreed to accept and reimburse the processor for items that meet the Company's quality control guidelines.

PREPAID INVENTORY--In an effort to increase the Company's supply of donor tissue, the Company has agreed to fund several tissue recovery agencies, in exchange for the first right of refusal for any donor tissue recovered. During 1998 and 1999, the Company had advanced $1,249,383 and $2,245,842 respectively to the tissue recovery agencies and recouped $754,750 and $1,988,318 respectively in donor tissue. At December 31, 1998 and 1999, the Company has yet to recover $494,633 and $733,733 respectively of its expenditures through donor tissue recovery. Prepaid inventory is classified in prepaid and other assets in the accompanying balance sheets. The Company has no ownership or control in these agencies, and funding can be discontinued at any time when donor tissue is no longer being supplied.

FOREIGN INVESTMENT--In August 1998, the Company received a 30% ownership in UFTB-Italia for no consideration. UFTB-Italia is an entity created in late 1998, which had no operations as of December 31, 1998. UFTB-Italia plans to recover, process, and distribute tissue in conjunction with training and technology supplied by the Company at UFTB-Italia's expense. Since the Company exercises no significant control over the UFTB-Italia operation, the Company has treated this investment on the cost basis, recognizing income only upon receipt of dividends. As of December 31, 1998 and 1999, the Company has not recorded any income from its interest in UFTB-Italia. As of December 31, 1999, the Company had $172,405 of outstanding accounts receivable due from UFTB-Italia. Total tissue distributions to UFTB-Italia in 1999 were $223,704.

LEASES--The Company leases various buildings, office equipment and fixtures under non-cancelable operating leases for various periods. The Company also leases various equipment under capital leases that are included in property, plant, and equipment in the accompanying balance sheets.

EMPLOYMENT AGREEMENTS--As of December 31, 1999, the Company had employment contracts with six officers of the Company, providing for total annual payments of approximately $815,000 through fiscal year 2003.

14. RELATED PARTIES

The Company has certain related party transactions with UFTB. Through April 15, 1999, UFTB recovered whole donor tissue and distributed conventional tissue. The Company processed this tissue for UFTB for a fee and compensated UFTB for the nonconventional tissue retained from the whole donor tissue. On April 15, 1999, the Company entered into two new agreements under which UFTB transferred to the Company all rights to conventional tissue distribution and national recovery programs, permitting UFTB to focus primarily on tissue recovery and UFTB settled amounts due to the Company. As of April 15, 1999, the total due from UFTB and the note receivable from UFTB was approximately $5,000,000. Under the terms of the agreements, UFTB transferred its unprocessed donor tissue and conventional tissue with a fair value of approximately $3,000,000 and equipment and fixtures with a fair value of approximately $90,000 to the Company as an offset against the existing due from stockholder and note receivable from stockholder. Additionally, UFTB agreed to repay the remaining balance by (a) offsetting recovery fees from April 15, 1999 through June 30, 1999 against the outstanding balance, which fees approximate $800,000, and
(b) making monthly payments through the end of 1999 to repay the remaining balance of approximately $1,200,000.

In addition to these operating transactions, the Company shares facilities, overhead and certain personnel with UFTB.

18. SUBSEQUENT EVENTS

As part of the agreement to purchase the assets of NTBN, Dr. Garrison was given the option to convert a $500,000 note due November 2002 or any portion of the note into Common Stock of the Company at the Series C Preferred stock price of $27.101. On February 15, 2000 Dr. Garrison exercised his option on 9,225 shares equivalent to $250,000. The value of the shares is a reduction of the $500,000 note payable, the balance of which at December 31, 1999 was $487,896. The $212,236 balance of the note, after exercising the stock conversion, will be repaid by April 2001, as the monthly payments will remain at the original amount until the note is paid off.

On March 30, 2000, the Company purchased the buildings and land (6.19 acres) the Company occupied under lease, plus an additional 20.82 acres of land for future expansion. The purchase price for the two buildings and 6.19 acres was $3,600,000 with the additional 20.82 acres priced at $624,600. The Company received a 20 year term loan in the amount of $2,800,000 to finance the purchase of the building and the 6.19 acres of land. Interest on the loan is at 30 day LIBOR plus 150 basis points. Simultaneous with entering into the $2,800,000 term loan, the Company entered into a swap agreement with a commercial bank which fixes its interest rate at 6.85%. The effective notional amount of the swap at March 30, 2000 was $2,800,000. The term loan is collateralized by the land and building. The term loan agreement contains various restrictive covenants, which limit among other things, leases, indebtedness, loans, and acquisitions. In addition the Company must satisfy certain financial ratios including fixed charge ratio at 1.25 to 1.00 or greater and funded debt to earnings before interest, taxes, depreciation and amortization of not greater than 4.00 to 1.00. The $1,424,600 balance of the amounts due for the building with 6.19 acres and additional 20.82 acres is financed from the $10,000,000 raised from the sale of Series C Preferred stock.

On April 27, 2000, the Company entered into a definitive agreement to acquire the net assets of a division of the University of Alabama Health Services Foundation, which has been doing business as the Alabama Tissue Center ("ATC"), in Birmingham, Alabama. The acquisition will be financed by a cash payment of $350,000 and the issuance of $3,500,000 in shares of the Company's common stock, valued at the Company's initial public offering price, plus an additional cash payment of $250,000 upon the achievement of certain milestones, with total possible consideration valued at $4,100,000. The acquisition of ATC will be accounted for under the purchase method of accounting.

19. COMMON STOCK SPLIT AND MERGER INTO DELAWARE CORPORATION (UNAUDITED)

The Company anticipates approving a common stock split. The conversion rate is not currently known. The Company's historical consolidated financial statements will be retroactively restated for this common stock split. The Company also anticipates that it will merge into a newly formed Delaware corporation.

INDEPENDENT AUDITORS' REPORT

To the Board of Directors of Regeneration Technologies, Inc.:

We have audited the accompanying statements of revenues and direct costs of the predecessor business of Regeneration Technologies, Inc. (the "Company"), a part of the University of Florida Tissue Bank, Inc., for the year ended December 31, 1997 and for the period from January 1, 1998 through February 11, 1998. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the statement of revenues and direct costs is free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the statements of revenues and direct costs. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall statements of revenues and direct cost presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the statements of revenues and direct costs present fairly, in all material respects, the revenues and direct costs of the Company for the year ended December 31, 1997 and for the period from January 1, 1998 through February 11, 1998, in conformity with accounting principles generally accepted in the United States of America.

As more fully described in Note 2 to the statements of revenues and direct costs, the Company was operated as a part of the University of Florida Tissue Bank, Inc. As a result, certain expense allocations have not been made in the accompanying statements of revenues and direct costs.

NOTES TO STATEMENTS OF REVENUES AND DIRECT COSTS

YEAR ENDED DECEMBER 31, 1997
AND PERIOD FROM JANUARY 1, 1998 TO FEBRUARY 11, 1998

1. ORGANIZATION

Regeneration Technologies, Inc., was incorporated in Florida on August 22, 1997, and began operations on February 12, 1998, following a contribution of assets by the University of Florida Tissue Bank, Inc. ("UFTB") of the Predecessor Business of Regeneration Technologies, Inc. (the "Company"). The Company processed human musculoskeletal tissue received from various tissue recovery agencies. The Company's processing transformed the tissue into either conventional or precision tooled allografts, some of which were patented. These allografts were distributed domestically and internationally, for use in spinal vertebrae repair, musculoskeletal reconstruction and fracture repair. The processed tissue included cortical dowels, cervical implants, cortical bone interference screws, and bone paste grafts.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION--The accompanying statements of revenues and direct costs reflect the operations of the Company, operating as a part of UFTB, and may not necessarily be indicative of the financial results had the Company been operating as a separate entity. Allocations for certain expenses, such as interest, corporate overhead and income taxes by UFTB are not included in these statements, as a reasonable methodology for allocation could not be made, and any allocation may not be indicative of the actual costs incurred by the Company.

INVENTORIES--Product and supply inventories were stated at the lower of cost or market, with cost determined by the first-in, first-out method.

PROPERTY, PLANT AND EQUIPMENT--Property, plant and equipment were stated at cost less accumulated depreciation and amortization. The cost of equipment under capital leases and leasehold improvements was amortized on the straight-line method over the shorter of the lease term or the estimated useful life of the asset. Depreciation was computed on the straight-line method over the following estimated useful lives of the assets:

Production equipment........................................  8 to 10 years
Leasehold improvements......................................  8 to 10 years
Office equipment, furniture, and fixtures...................   5 to 7 years
Computer hardware and software..............................        3 years

Depreciation and amortization expense was approximately $252,447 for the year ended December 31, 1997 and $48,272 for the period from January 1, 1998 to February 11, 1998.

RESEARCH AND DEVELOPMENT COSTS--Research and development costs were expensed as incurred.

REVENUE RECOGNITION--Revenue was recognized at the time the Company shipped the processed tissue. Revenues were reported gross of any management services fees the Company incurred to distribute its products. Any other revenues directly related to the Company's core operations were recognized when all significant contractual obligations were satisfied.

USE OF ESTIMATES--The preparation of the accompanying statements of revenues and direct costs in conformity with generally accepted accounting principles required management to make estimates and

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145(a) of the General Corporation Law of the State of Delaware ("DGCL") provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that he is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no cause to believe his conduct was unlawful.

Section 145(b) of the DGCL provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he acted in any of the capacities set forth above, against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted under similar standards, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine that despite the adjudication of liability, such person is fairly and reasonably entitled to be indemnified for such expenses which the court shall deem proper.

Section 145 of the DGCL further provides that to the extent a director or officer of a corporation has been successful in the defense of any action, suit or proceeding referred to in subsections (a) and (b) or in the defense of any claim, issue or matter therein:

II-1


- he shall be indemnified against expenses actually and reasonably incurred by him in connection therewith;

- that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled;

- and that the corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him or incurred by him in any such capacity or arising out of his status as such whether or not the corporation would have the power to indemnify him against such liabilities under such Section 145.

Section 102(b)(7) of the DGCL provides that a certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director provided that such provision shall not eliminate or limit the liability of a director:

- for any breach of the director's duty of loyalty to the corporation or its stockholders;

- for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

- under Section 174 of the DGCL; or

- for any transaction from which the director derived an improper personal benefit.

Article Ninth of Regeneration Technologies's Certificate of Incorporation contains substantially the same provisions for indemnification as those contained in Section 145 of the DGCL. Additionally, Article Ninth provides that in any judicial proceeding in which a person seeks indemnification pursuant to Article Ninth, the burden of proving that such person is not entitled to indemnification shall be on Regeneration Technologies. Article Ninth further provides that any person who successfully establishes a right to indemnification, in whole or in part, under Article Ninth in any such proceeding shall be indemnified by Regeneration Technologies against expenses incurred (including attorneys' fees) in establishing such right to indemnification. Finally, Article Ninth provides that in the event the DGCL is amended to expand further the indemnification permitted to the persons covered by Article Ninth, Regeneration Technologies shall indemnify such persons to the fullest extent permitted by the DGCL, as so amended. Reference is made to the Regeneration Technologies' Amended Certificate of Incorporation and By-Laws filed as Exhibits 3.1 and 3.2, respectively.

Article Tenth of Regeneration Technologies's Certificate of Incorporation, states that to the fullest extent permitted by the DGCL, no director of Regeneration Technologies shall be personally liable to Regeneration Technologies, any of its stockholders or any other person or entity for monetary damages for breach of fiduciary duty owed to Regeneration Technologies, its stockholders or such other person or entity owing to such director's position as a director of Regeneration Technologies.

Regeneration Technologies intends to enter into indemnification agreements with its current directors and executive officers. Regeneration Technologies intends to insure its directors and officers against losses arising from any claim against them as such for wrongful acts or omission, subject to certain limitations.

Under Section 8 of the Underwriting Agreement, the underwriters are obligated, under certain circumstances, to indemnify officers, directors and controlling persons of Regeneration Technologies against certain liabilities, including liabilities under the Securities Act of 1933. Reference is made to the form of Underwriting Agreement filed as Exhibit 1.1 hereto.

ITEM 17. UNDERTAKINGS

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes to provide to the underwriters at the closing specified in the Underwriting Agreement, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, as amended, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

- 7 -

(ii) At any time after the Company becomes eligible to file a Registration Statement on Form S-3 (or any successor form relating to secondary offerings), holders of Common Stock issued or issuable upon conversion of the Class C Preferred Stock will have the right to require the Company to effect an unlimited number of Registration Statements on Form S-3 (or such successor form) of Class C Registrable Shares having an aggregate offering price in each registration on Form S-3 in excess of $500,000 (based on the then current public market price). Such Stockholders shall have the right, by giving written notice to the Company within thirty (30) days after the Company provides its notice, to elect to have included in such registration such of their Class C Registrable Shares as such Stockholders may request in such notice of election. The Company shall, as expeditiously as possible, use its best efforts to effect the registration on Form S-3, or such successor form, of all Class C Registrable Shares which the Company has been requested to register.

(iii) Subject to the terms of Section 1.4(b) hereof, the Company shall be required to effect two registrations pursuant to paragraph (a) above and an unlimited number of registrations pursuant to paragraph (b) above; provided, however, that the Company shall not be required to effect any registration (other than on Form S-3 or any successor form relating to secondary offerings) within six (6) months after the effective date of any other Registration Statement of the Company, provided that the Class C Stockholders were provided an opportunity to effect the sale of Class C Registrable Shares pursuant to such Registration Statement; and provided further that the Company shall not be required to effect more than two registrations pursuant to paragraph (b) above in any 12-month period.

1.4 Incidental Registration.

(a) Whenever the Company proposes to file a Registration Statement (including pursuant to subsection 1.3) at any time and from time to time, it will, prior to such filing, give written notice to all Stockholders of its intention to do so and, upon the written request of a Stockholder or Stockholders given within twenty (20) days after the Company provides such notice (which request shall state the intended method of disposition of such Registrable Shares), the Company shall use its best efforts to cause all Registrable Shares which the Company has been requested by such Stockholder or Stockholders to register to be registered

- 8 -

under the Securities Act to the extent necessary to permit their sale or other disposition in accordance with the intended methods of distribution specified in the request of such Stockholder or Stockholders; provided that the Company shall have the right to postpone or withdraw any registration effected pursuant to this subsection 1.4 without obligation to any Stockholder.

(b) In connection with any offering under this subsection 1.4 involving an underwriting, the Company shall not be required to include any Registrable Shares in such underwriting unless the holders thereof accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it, and then only in such quantity as will not, in the opinion of the underwriters, have a material adverse effect on the success of the offering by the Company. If in the opinion of the managing underwriter the registration of all, or part of, the Registrable Shares which the holders have requested to be included would materially and adversely affect such public offering, then the Company shall be required to include in the underwriting only that number of Registrable Shares, if any, which the managing underwriter believes may be sold without causing such adverse effect; provided that no persons or entities other than the Company, the Stockholders and persons or entities holding registration rights granted in accordance with subsection 1.11 hereof shall be permitted to include securities in the offering. If the number of Registrable Shares to be included in the underwriting in accordance with the foregoing is less than the total number of shares which the holders of Registrable Shares have requested to be included, then the number of shares to be offered shall be reduced or limited in the following order of priority: (x) first, the securities proposed by the Company to be sold for its own account
(except where the Company is the party that initiated such registration); (y) second, the number of shares to be offered by all other holders of securities of the Company other than the holder of Registrable Shares or other holders who have registration rights to the extent necessary to reduce the total number of shares as recommended by such managing underwriters; and (z) third, if further reduction or limitation is required, the number of shares to be offered for the account of the Stockholders shall be reduced or limited on a pro rata basis in proportion to the relative number of Registrable Shares of the Stockholders participating in such registration. Notwithstanding the foregoing sentence, in the case of the first registration affected pursuant to Section 1.3(a), 1.3(b) or 1.3(c) hereof, if the number of Registrable Shares to be included in such underwriting is less than the total number of shares which the holders of Registrable Shares have requested to be included, then the number of shares to be offered shall be reduced or limited on a pro rata basis in proportion to the relative number of Registrable Shares of the Stockholders participating in such registration (regardless of whether pursuant to Section 1.3 or this Section 1.4), provided, however, that if there is a such a reduction or limitation, then the Stockholder that has not requested such a registration shall be deemed to have expended one of their two registrations pursuant to Section 1.3(a)(i), 1.3(b)(i) or 1.3(c)(i), as the case may be, as long as such Stockholder has been able to include in such registration at least 66 2/3% of the Registrable Shares that such stockholder desired to include in such registration.

(c) Withdrawal Election. If, as a result of the proration provisions of the Section 1.4, any Stockholder shall not be entitled to include at least 50% of the Registrable

- 9 -

Shares in such Incidental Registration pursuant to Section 1.4(a) that such Stockholder has requested to be included, such Stockholder may elect to withdraw his, her or its request to include Registrable Shares in such registration (a "Withdrawal Election") without incurring any liability for his, her or its fees and expenses; provided, however, that a Withdrawal Election shall be irrevocable and, after making a Withdrawal Election, a Stockholder shall no longer have any right to include Registrable Shares in the Registration as to which such Withdrawal Election is made.

1.5 Registration Procedures. If and whenever the Company is required by the provisions of this Agreement to use its best efforts to effect the registration of any of the Registrable Shares under the Securities Act, the Company shall:

(a) Prepare and file with the Commission a Registration Statement with respect to such Registrable Shares and use its best efforts to cause such Registration Statement to become effective; provided that before filing a Registration Statement or prospectus or any amendment or supplement thereto, including documents incorporated by reference after the initial filing of any Registration Statement, the Company shall furnish to the Stockholders of the Registrable Shares covered by such Registration Statement (such shares, "Registered Shares") and the underwriters, if any, copies of all such documents proposed to be filed, which documents will be subject to the review of such Stockholders and underwriters.

(b) Prepare and file with the Commission such amendments and post-effective amendments to a Registration Statement as may be necessary to keep such registration effective for a period of six (6) months or until the Stockholder or Stockholders have completed the distribution described in the Registration Statement relating thereto, whichever first occurs; provided, however, that the Company, in good faith, may delay the filing of any amendment or supplement to the Registration Statement for a reasonable period of time, not to exceed 120 days, in order to permit the Company (A) to effect disclosure or disposition or consummation of any transaction requiring confidential treatment which is being actively pursued at such time and which would require disclosure in the Registration Statement or (B) to negotiate, effect or complete any transaction which the Company reasonably believes might be jeopardized, delayed or made more costly to the Company by disclosure in the Registration Statement; and provided further, however, that (i) such 6 month period shall be extended for a period of time equal to the period the Stockholder refrains from selling any securities included in such registration in accordance with the provisions of Section 1.10 hereof;
(ii) such 6 month period shall be extended by the number of days during the period from and including the date of the giving of notice pursuant to
Section 1.5(e) hereof to and including the date when each Stockholder of Registrable Shares covered by such Registration Statement shall have received the copies of the supplemented or amended prospectus contemplated by Section 1.5(e) hereof; and (iii) in the case of any registration of Registrable Shares on Form S-3 which are intended to be offered on a continuous or

- 10 -

delayed basis, such 6 month period shall be extended, if necessary, to keep the Registration Statement effective until all such Registrable Shares are sold, provided that Rule 415, or any successor rule under the Securities Act, permits an offering on a continuous or delayed basis, and provided further that applicable rules under the Securities Act governing the obligation to file a post-effective amendment permit, in lieu of filing a post-effective amendment which (y) includes any prospectus required by Section l0(a)(3) of the Securities Act or (z) reflects facts or events representing a material or fundamental change in the information set forth in the Registration Statement, the incorporation by reference in the Registration Statement of periodic reports filed pursuant to Section 13 or 15(d) of the Exchange Act that contain the information required to be included in (y) and (z) above;

(c) Cause the related prospectus to be supplemented by any required prospectus supplement, and as so supplemented, to be filed pursuant to Rule 424 under the Securities Act; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement or supplement to such prospects;

(d) Furnish such number of prospectuses and other documents incident thereto, including any amendment of or supplement to the prospectus as a Stockholder from time to time may reasonably request;

(e) Notify each seller of Registered Shares covered by such Registration Statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and at the request of any such seller, prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(f) Cause all such Registered Shares to be listed on each securities exchange on which similar securities issued by the Company are then listed or, if not then listed, cause such Registered Shares to be included in whatever exchange or national automated quotation system the Board of Directors determines is appropriate;

- 11 -

(g) Provide a transfer agent and registrar for all Registered Shares and a CUSIP number for all such Registered Shares, in each case not later than the effective date of such registration;

(h) Make available for inspection during regular business hours by any seller of Registrable Shares, any underwriter participating in any disposition pursuant to such Registration Statement, and any attorney, accountant or other agent retained by any such seller or underwriter (collectively, the "Inspectors"), all financial and other records, pertinent corporate documents and properties of the Company (collectively the "Records") as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company's officers, directors, employees and independent accountants to supply all information reasonably requested by such seller, underwriter, attorney or accountant in connection with such Registration Statement. Records which the Company determines, in good faith, to be confidential and which it notifies the Inspectors are confidential shall not be disclosed by the Inspectors unless (A) the disclosure of such Records is, in the opinion of counsel for the selling Stockholders, reasonably necessary to avoid or correct any misstatement or omission in the Registration Statement, (B) the release of such Records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, or (C) the disclosure of such Records is required by any governmental regulatory body with jurisdiction over any seller of Registrable Shares. Such seller, upon learning, that disclosure of such Records is sought in a court of competent jurisdiction, shall notify the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of the Records deemed confidential;

(i) Cooperate with the sellers of Registered Shares and the managing underwriter(s), if any, to facilitate the timely preparation and delivery of certificates representing the Registered Shares to be sold, without any restrictive legends, in such denominations and registered in such names as the managing underwriter(s) may request at least two business days prior to any sale thereof to the underwriters, if applicable;

(j) Participate, to the extent reasonably requested by the managing underwriter for the offering or the selling Stockholders, in efforts to sell the Registrable Shares under the offering (including, without limitation, participating in "roadshow" meetings with prospective investors) that would be customary for underwritten primary offerings of a comparable percent of equity securities by the Company;

(k) Obtain from its accountants "cold-comfort" letters, dated the effective date of the Registration Statement and the date of the closing of the sale of the Registered Shares, and addressed to the Company and the selling Stockholders, in form and substance as are customarily issued in connection with underwritten public offerings;

- 12 -

(l) Obtain from its counsel an opinion, addressed to the selling Stockholders, with respect to the offering in form and substance reasonably satisfactory to a majority-in-interest of such Stockholders;

(m) Otherwise use its best efforts to comply with all applicable rules and regulations of the Commission, and make available to its security Stockholders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months, but not more than eighteen months, beginning with the first month after the effective date of the Registration Statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act;

(n) In connection with any underwritten offering pursuant to a Registration Statement filed pursuant to Section 1 hereof, the Company will enter into any underwriting agreement reasonably necessary to effect the offer and sale of Common stock, provided such underwriting agreement contains customary underwriting, indemnification and contribution provisions; provided, however, that no Stockholder will be liable for indemnification or contribution in excess of the net proceeds such Stockholder received in the offering;

(o) Use its best efforts to register or qualify such Registrable Shares under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in such jurisdictions of the Registrable Shares owned by such seller provided that the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph, (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction);

(p) Use its best efforts to cause such Registrable Shares covered by such Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the sellers thereof to consummate the disposition of such Registrable Shares; and

(q) Take all such other actions as the underwriters, if any, and a majority-in-interest of the selling Stockholders reasonably request in order to expedite or facilitate the disposition of such Registrable Shares (including, without limitation, effecting a stock split or combination of shares).

1.6 Allocation of Expenses. The Company will pay all Registration Expenses of all registrations under this Agreement; provided, however, that if a registration under subsection 1.3 is withdrawn at the request of the Class B or Class C Stockholders, as applicable, requesting such registration (other than as a result of information concerning the business or financial condition of the Company which is made known to the Stockholders after

- 13 -

the date on which such registration was requested) and if the requesting Stockholders, elect not to have such registration counted as a registration requested under subsection 1.3, the requesting Stockholders shall pay the Registration Expenses of such registration pro rata in accordance with the number of their Registrable Shares included in such registration. For purposes of this Section, the term "Registration Expenses" shall mean all expenses incurred by the Company in complying with this Article 1, including, without limitation, all registration and filing fees, exchange listing fees, printing expenses, fees and disbursements of counsel for the Company and the fees and expenses of one counsel selected by the selling Stockholders, as applicable, to represent the selling Stockholders, as applicable, state Blue Sky fees and expenses, and the expense of any special audits incident to or required by any such registration, but excluding underwriting discounts, selling commissions and the fees and expenses of the selling Stockholders' own counsel (other than the counsel selected to represent all selling Stockholders).

1.7 Indemnification and Contribution. In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, the Company will indemnify and hold harmless the seller of such Registrable Shares, each underwriter of such Registrable Shares, and each other person, if any, who controls such seller or underwriter within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages or liabilities, joint or several, to which such seller, underwriter or controlling person may become subject under the Securities Act, the Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arise out of or are based upon the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and the Company will promptly reimburse such seller, underwriter and each such controlling person upon demand for any legal or any other expenses reasonably incurred by such seller, underwriter or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in such Registration Statement, preliminary prospectus or prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by or on behalf of such seller, underwriter or controlling person specifically for use in the preparation thereof.

In the event of any registration of any of the Registrable Shares under the Securities Act pursuant to this Agreement, each seller of Registrable Shares, severally and not jointly, will indemnify and hold harmless the Company, each of its directors and officers and each underwriter (if any) and each person, if any, who controls the Company or any such underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Company, such directors and

- 14 -

officers, underwriter or controlling person may become subject under the Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if but only if, the statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of such seller, specifically for use in connection with the preparation of such Registration Statement, prospectus, amendment or supplement; provided, however, that the obligations of such Stockholders hereunder shall be limited to an amount equal to the proceeds to each Stockholder of Registrable Shares sold as contemplated herein.

Each party entitled to indemnification under this subsection 1.7 (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not be unreasonably withheld); and, provided, further, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Article 1. The Indemnified Party may participate in such defense at such party's expense; provided, however, that the Indemnifying Party shall pay such expense if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between the Indemnified Party and any other party represented by such counsel in such proceeding. No Indemnifying Party in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation, and no Indemnified Party shall consent to entry of any judgment or settle such claim or litigation without the prior written consent of the Indemnifying Party.

In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any holder of Registrable Shares exercising rights under this Agreement, or any controlling person of any such holder, makes a claim for indemnification pursuant to this subsection 1.7 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this subsection 1.7 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of any such selling

- 15 -

Stockholder, as applicable, or any such controlling person in circumstances for which indemnification is provided under this subsection 1.7; then, in each such case, the Company and such Stockholder will contribute to the aggregate losses, claims, damages, or liabilities to which they may be subject (after contribution from others) in such proportion as is appropriate to reflect the relative fault of the Stockholder on the one hand and the Company on the other in connection with the action that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, that in no event shall any contribution by a holder exceed the proceeds to it of all Registrable Shares sold by it pursuant to such Registration Statement, and (B) no person or entity guilty of fraudulent misrepresentation, within the meaning of Section 11(f) of the Securities Act, shall be entitled to contribution from any person or entity who is not guilty of such fraudulent misrepresentation.

1.8 Indemnification with Respect to Underwritten Offering. In the event that Registrable Shares are sold pursuant to a Registration Statement in an underwritten offering pursuant to subsection 1.3(a), 1.3(b) or 1.3(c), the Company agrees to enter into an underwriting agreement containing customary representations and warranties of an issuer of the securities being registered and customary covenants and agreements to be performed by such issuer, including without limitation customary provisions with respect to indemnification by the Company of the underwriters of such offering, provided that such agreement shall not provide that the Stockholders are subject to indemnification obligations greater than as set forth herein.

1.9 Information by Holder. Each holder of Registrable Shares included in any registration shall furnish to the Company such information regarding such holder and the distribution proposed by such holder as the Company may request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Article 1.

1.10 "Market Stand-Off Agreement.

(a) Each Stockholder, if requested by the Company and an underwriter of Common Stock or other securities of the Company, shall agree not to sell or otherwise transfer or dispose of any Registrable Shares or other securities of the Company held by such Stockholder for a specified period of time (not to exceed 180 days) following the effective date of a Registration Statement; provided, that:

(i) such agreement shall only apply to the first such Registration Statement covering Common Stock of the Company to be sold on its behalf to the public in an underwritten offering; and

- 16 -

(ii) all Stockholders holding not less than the number of shares of Common Stock held by such Stockholder (including shares of Common Stock issuable upon the conversion of Shares, or other convertible securities, or upon the exercise of options, warrants or rights) and all officers and directors of the Company enter into similar agreements.

(c) The agreements described in subsection (a) above shall be in writing in a form satisfactory to the Company and such underwriter. The Company may impose stop-transfer instructions with respect to the Registrable Shares or other securities subject to the foregoing restriction until the end of the stand-off period.

1.11 Limitations on Subsequent Registration Rights. The Company shall not, without the prior written consent of Stockholders holding at least 66 2/3% of the Registrable Shares, enter into any agreement (other than this Agreement) with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder (a) to include securities of the Company in any registration filed under subsection 1.3 or 1.4, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only on terms substantially similar to the terms on which holders of Registrable Shares may include shares in such registration, including the terms of Section 1.4(b) hereof; provided, however, that under the terms of such agreement the number of Registrable Shares to be included by the initiator of a demand registration pursuant to Section 1.3 hereof shall not be reduced to allow such holder or prospective holder to include securities in such registration or (b) to make a demand registration which could result in such registration statement being declared effective prior to the initial public offering.

1.12 Rule 144 Requirements. After the earliest of (i) the closing of the sale of securities of the Company pursuant to a Registration Statement, (ii) the registration by the Company of a class of securities under Section 12 of the Exchange Act, or (iii) the issuance by the Company of an offering circular pursuant to Regulation A under the Securities Act, the Company agrees to:

(a) Comply with the requirements of Rule 144(c) under the Securities Act with respect to current public information about the Company;

(b) use its best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and

(c) furnish to any holder of Registrable Shares upon request
(i) a written statement by the Company as to its compliance with the requirements of said Rule 144(c), and the reporting requirements of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), (ii) a copy of the most recent annual

- 17 -

or quarterly report of the Company, and (iii) such other reports and documents of the Company as such holder may reasonably request to avail itself of any similar rule or regulation of the Commission allowing it to sell any such securities without registration.

1.13 Selection of Underwriter. In the case of any registration effected pursuant to this Article I, the Company shall have the right to designate the managing underwriter in any underwritten offering, subject to the approval of the holders of a majority of the Registrable Shares requested to be included in such offering, which approval shall not be unreasonably withheld.

1.14 Mergers, Etc. The Company shall not, directly or indirectly, enter into any merger, consolidation, or reorganization in which the Company shall not be the surviving corporation unless the proposed surviving corporation shall, prior to such merger, consolidation, or reorganization, agree in writing to assume the obligations of the Company under this Article 1, and for that purpose references hereunder to "Registrable Shares" shall be deemed to be references to the securities that each Stockholder would be entitled to receive in exchange for Registrable Shares under any such merger, consolidation, or reorganization; provided, however, that the provisions of this Article I shall not apply in the event of any merger, consolidation, or reorganization in which the Company is not the surviving corporation if all Stockholders are entitled to receive in exchange for their Registrable Shares consideration consisting solely of (i) cash, (ii) securities of the acquiring corporation that may be immediately sold to the public without registration under the Securities Act, or
(iii) securities of the acquiring corporation that the acquiring corporation has agreed to register within ninety (90) days of completion of the transaction for resale to the public pursuant to the Securities Act.

ARTICLE II
TRANSFERS OF CERTAIN RIGHTS

2.1 The rights granted to the Investors under this Agreement may be transferred by such Investor to an affiliate, partner, shareholder or immediate family member of such Investor or any transferee who after such transfer holds at least 20% of the Investor's Registrable Shares; provided, however, that the Company is given written notice by the transferee at the time of such transfer stating the name and address of the transferee and identifying the securities with respect to which such rights are being transferred, and that the Company gives its consent to the transfer of rights to any transferee which is not an affiliate, partner, shareholder, or immediate family member of the Investor, which consent shall not be unreasonably withheld.

2.2 Transferees. Any transferee to whom rights under this Agreement are transferred shall, as a condition to such transfer, deliver to the Company a written instrument by which such transferee agrees to be bound by the obligations imposed upon the Investor under this Agreement to the same extent as if such transferee were the Investor.

(b) "New Securities" shall mean any capital stock of the Company regardless of either now authorized, and rights, options or warrants to purchase capital stock, and securities of any type whatsoever which are, or may become, convertible into capital stock; provided, however, that the term "New Securities" does not include (i) the shares issuable under the Purchase Agreement, (ii) shares of Common Stock issuable upon conversion of the Class A Preferred Stock, the Class B Preferred Stock, or the Class C Preferred Stock;

Each of the Preferred Stockholders shall have 30 days from the date of any such notice to agree to purchase all or part of its pro rata share of such New Securities for the price and upon the general terms and conditions specified in the Company's notice by giving written notice to the Company stating the quantity of New Securities to be so purchased. The Preferred Stockholders shall have a right of oversubscription such that if any Preferred Stockholder fails to purchase all of its pro rata share of the New Securities, the other Preferred Stockholders, among them, shall have the right to purchase up to the balance of such New Securities not so purchased.

(d) To the extent that the Preferred Stockholders fail to exercise the foregoing preemptive right with respect to any New Securities within such 30-day period, the Company may Within 90 days thereafter sell any or all of such New Securities not agreed to be purchased

-5-

by the preferred Stockholders, at a price and upon general terms no more favorable to the purchaser thereof than specified in the notice given to the Preferred Stockholders pursuant to paragraph (c) above. In the event the Company has not sold such New Securities within such 90-day period, the Company shall not thereafter issue or sell any New Securities without first offering such New Securities to the Preferred Stockholders in the mariner provided above.

3. Right of First Offer.

(a) Restrictions on Transfers.

(i) Except as otherwise provided in subsection 3(b) below, a Preferred Stockholder or a Specified Common Stockholder (as defined below) shall sell, assign, transfer, pledge, hypothecate or otherwise dispose of, by operation of law or otherwise (collectively transfer), any of the Shares, or any interest therein, only in accordance with the terms of this Section 3. A "Specified Common Stockholder" shall mean James Grooms, Richard Allen, Frank & Glowczewskie Jr. and Nancy Holland.

(ii) Notwithstanding the foregoing, a Preferred Stockholder or a Specified Common Stockholder may transfer Shares or Common Stock, as the case may be, to (i) any "affiliate" of such Stockholder (as such term are defined in the rules and regulations promulgated under the Securities Act), (ii) an immediate family member of such Stockholder, (iii) in the case of any Preferred Stockholder that is a partnership, a partner of such partnership or (iv) in the case :of any Preferred Stockholder that is a corporation, a stockholder of such corporation, provided that such Shares or Common Stock, as the case may be, shall remain subject to this Agreement (including without limitation the restrictions on transfer set forth in this Section 3) and such permitted transferee shall, as a condition to such transfer, deliver to the Company a written instrument confirming that such transferee shall be bound by all of the terms and conditions of this Agreement.

(b) Receipt and Communication of Offer. Subject to the terms of Section 3(a) hereof if at any time a Preferred Stockholder or Specified Common Stockholder (the "Selling Stockholder") desires to transfer for cash, cash equivalents or any other form of consideration (including a promissory note) all or any part of the Shares or the Common Stock, as the case may be, or any shares of Common Stock or other capital stock of the Company acquired by such Selling Stockholder subsequent to the date hereof (such shares of Common Stock and the Shares are collectively referred to as the "Selling Stockholder Shares"), the Selling Stockholder shall submit a written offer (the "Offer") to sell the Selling Stockholder Shares (the "Offered Shares") to the Company and the other Preferred Stockholders specifying the terms and conditions, including price pursuant to which the Selling Stockholder proposes to sell such Offered Shares. The Offer shall disclose the number of Offered Shares proposed to be sold, the total number of shares of all classes of the Company's capital stock owned by the Selling Stockholder, the terms and conditions, including price, of the proposed sale, and any other material facts relating to the proposed sale. The Offer shall further state that the Company may acquire, in accordance with the provisions of this Agreement or a Stock Restriction Agreement (as defined below), as the case may be, all or any portion of the Offered Shares for the price and upon the other terms and

-6-

conditions including deferred payment (if applicable), set forth therein, provided, however, that if the purchase price for the Offer is proposed to be paid, in whole or in part, in securities of a third party, the Company may instead pay cash based on the fair market value of such securities.

(c) Company's Right. The Company shall have the absolute right, by delivery of written notice to the Selling Stockholder (as hereinafter provided), to repurchase all or a portion of the Offered Shares offered by a Preferred Stockholder in accordance with the terms of subsection d hereof and of a Specified Common Stockholder in accordance with the terms of the stock restriction agreement executed by such Specified Common Stockholder upon issuance of the shares of Common Stock (the "Stock Restriction Agreement").

(d) Company Notice of Intent to Repurchase. If the Company desires to repurchase all or any part of the Offered Shares, it shall communicate in writing (the "Notification") its election to repurchase to the Selling Stockholder, which communication shall state the number of Offered Shares the Company desires to repurchase and shall be delivered in person or by facsimile to the Selling Stockholder within 25 days of the Offer Date. The Notification shall, when taken in conjunction with the Offer, be deemed to constitute a valid, legally binding and enforceable agreement for the sale and repurchase of such Offered Shares. Sales of the Offered Shares to be sold to the Company pursuant to this Section shall be made at the offices of the Company no later than the 60th day following the Offer Date (or if such 60th day is not a business day, then on the next succeeding business day). Such sales shall be effected by Selling Stockholder's delivery to the Company of a certificate or certificates evidencing ownership of the Offered Shares to be repurchased by it, duly endorsed for transfer to the Company, against payment to the Selling Stockholder of the repurchase price therefor by the Company.

(e) Preferred Stockholders' Right. If the Company elects not to exercise its right to repurchase all the Offered Shares under this Section 3 or under the terms of the applicable Stock Restriction Agreement, each Preferred Stockholder shall have the option, but not the obligation, to purchase its pro rata share of the remaining Offered Shares on the same terms as specified in the Offer. A Preferred Stockholder's pro rata share, for purposes of this subsection 3(e), shall equal a fraction, the numerator of which is the number of shares of Common Stock or Common Stock issuable upon conversion of the Preferred Stock which such Preferred Stockholder then holds (the "Preferred Stockholder's Stock"), and the denominator of which is the aggregate number of shares of Preferred Stockholder's Stock held by all Preferred Stockholders exercising their purchase rights under this Section 3(e). After the expiration of the 25-day period in
Section 3(d) but within 40 days after the Offer Date, any electing Preferred Stockholders shall give notice to the Selling Stockholder and the Company stating whether or not it elects to exercise its option, the number of Offered Shares, if any, it elects to purchase, and a date and time for consummation of the purchase not more than 60 days after the Offer Date. Failure by a Preferred Stockholder to give such notice within such time period shall be deemed an election by it not to exercise its option. If more than one Preferred Stockholder exercises its purchase option and the aggregate number of remaining Offered Shares sought to be purchased by such Preferred Stockholders exceeds the aggregate number of remaining Offered Shares, the number of remaining Offered Shares to be purchased by each such Preferred Stockholder shall be pro rated based on its respective equity interest in the Company on a fully diluted basis.

-7-

(f) If the aggregate number of Offered Shares that the Company and the Preferred stockholders elect to purchase is less than all of the Offered Shares, then the Company and the preferred Stockholder shall not be entitled to purchase any of the Shares. The Selling older shall thereafter be free to offer all of the Offered Shares described in the Offer to a party, at a price and on terms no less favorable to such Selling Stockholder than the price the terms set forth in the Offer. No less than 15 days prior to consummating a sale to a third (the "proposed Transferee"), the Selling Stockholder shall give the Company notice of the identity of the Proposed Transferee. If the Proposed Transferee is a Competitor of the Company defined below), then the Selling Stockholder may not consummate the proposed transfer without the approval of the Company. A "Competitor" shall mean an entity engaged in engineering, processing, distributing or developing tissue-regeneration products.

Tenant will simultaneously with such request give Landlord (i) the name and address of the proposed assignee or subtenant (ii) the terms of the proposed assignment or sublease, (iii) reasonably satisfactory and complete information about the nature, financial condition, business and business history of the proposed assignee or subtenant, and its proposed initial use of the Leased Premises, and (iv) a fee in the amount of $1,000.00 to reimburse Landlord for all its expenses including, without limitation, reasonable attorneys fees associated with Tenant's request to assign, sublet or otherwise encumber the Leased Premises under the terms of the Lease. The consent by Landlord to any assignment or subletting shall not constitute a waiver of the necessity for such consent to any subsequent assignment or subletting. Within fifteen days after Landlord's receipt of Tenants proposed assignment or sublease and all required information concerning the proposed sublessee or assignee, Landlord shall have the following options: (1) as to a requested sublease with a sublease term that coincides with ninety-five percent or more of the remaining term of this Lease, cancel this Lease as to the Leased Premises or portion Thereof proposed to be sublet (provided, however, that Tenant shall have ten (10) days to nullify Landlord's cancellation of this Lease by written notice to Landlord that it is withdrawing the sublease request); (2) consent to the proposed assignment or sublease, and, if the rent due and payable by any assignee or sublessee under any such permitted assignment or sublease (or a combination of the rent payable under such assignment or sublease plus any bonus or any other consideration or any payment incident thereto) exceeds the rent payable under this Lease for such space, Tenant shall pay to Landlord all such excess rent and other excess consideration, less Tenant's reasonable expenses incurred in connection with such subletting, including without limitation, reasonable brokerage commissions, improvements allowances, and alteration costs, within ten days following receipt thereof by Tenant or (3) refuse, in Landlord's reasonable judgment, to consent to the proposed assignment or sublease, which refusal shall be deemed to have been exercised unless Landlord gives Tenant written notice providing otherwise. Upon the occurrence of an event of default, if all or any part of the Leased Premises are then assigned or sublet, Landlord, in addition to any other remedies provided by this Lease or provided by law may, at its option, collect directly from the assignee or sublessee all rents becoming due to Tenant by reason of the assignment or sublease. Any collection directly by Landlord from the assignee or sublessee shall not be construed to constitute a novation or a release of Tenant or any guarantor from the further performance of its obligations under this Lease. Tenant shall deliver to Landlord within twenty (20) days after any assignment or subletting a copy of the executed assignment or sublease agreement. Any assignment or sublease shall provide that the assignee or subtenant shall comply with all applicable terms and conditions of this Lease to be performed by Tenant hereunder. The permitted use of the Leased Premises shall not change in connection with any assignment or sublease.

(c) Rents received by Landlord from any reletting pursuant to Subsection
(a)(iii) above, shall be applied first to the payment of any of the items enumerated in Subsection (b) above, in such order as Landlord shall deem appropriate, and second to the payment of rent and other sums due and unpaid by Tenant hereunder as of the date of Landlord's receipt of said rents.

15

notwithstanding any such reletting without termination, Landlord may at any time thereafter elect to terminate this Lease for such previous breach provided it has not been cured.

(iv) the reasonable costs of removing any of Tenant's property from the Leased Premises, and, if same be stored, the reasonable cost of transporting and storing same (if Landlord shall store such property in a Building then Landlord shall be entitled to a reasonable storage fee hereunder); (v) all brokerage fees and commissions (prorated for the unexpired portion of the Term)incurred by Landlord in reletting the Leased Premises; and (vi) compensation for the loss of profits occasioned by the breach and resultant termination of this Lease, which loss the parties agree shall be determined by calculating the total amount of Rent to be paid by Tenant, and any other charges to be paid by Tenant, as if this Lease had not been terminated, from the date of termination to the expiration date and deducting therefrom The fair market rent value of the Leased Premises for a like period expected to be collected by Landlord during such period.

(g) Tenant hereby waives all rights of redemption, now or hereafter granted, to the extent such rights may be lawfully waived.

(h) Pursuit of any of the foregoing remedies shall not preclude pursuit of any other remedy herein provided or any other remedy provided by law or at equity, nor shall pursuit of any remedy herein provided constitute an election of remedies thereby excluding the later election of an alternate remedy, or a forfeiture or waiver of any Annual Gross Rent, or other Additional Rent or other charges and assessments payable by Tenant and due to Landlord hereunder or of any damages accruing to Landlord by reason of violation of any of the terms, covenants, warranties and provisions herein contained.

Section 502(b)(7) of the Bankruptcy Code, including, without limitation, reasonable attorneys' fees incurred by Landlord by reason of Tenant's bankruptcy.

(d) Nothing contained in this Section 15.3 shall be deemed in any manner to limit Landlord's rights and remedies under the Bankruptcy Code, as presently existing or as may hereafter be amended.

(ii) if a petition is filed by or against Tenant under the Bankruptcy Code and such petition is not vacated within one hundred twenty (120) days. In either of such events, this Lease and all rights of Tenant hereunder shall automatically terminate with the same force and effect as if the date of either such event were the date stated herein for the expiration of the Term, and Tenant shall vacate and surrender the Leased Premises, but shall remain liable as herein provided.

ARTICLE 19. MISCELLANEOUS

19.1. Waiver.

Pursuit of any one or more of the remedies set forth in Article 15 above shall not preclude pursuit of any one or more of the other remedies provided elsewhere in this Lease or provided by law, nor shall pursuit of any remedy constitute forfeiture or waiver of any rent or damages accruing to Landlord or Tenant by reason of the violation of any of the terms, provisions or covenants of this Lease. Failure by Landlord or Tenant to enforce one or more of the remedies provided upon an event of default shall not be deemed or construed to constitute a waiver of the default or of any other violation or breach of any of the terms, provisions and covenants contained in this Lease. Without limiting the generality of the foregoing, no action taken or not taken by Landlord or Tenant under the provisions of this Section or any other provision of this Lease (including, by way of example rather than of limitation, the Landlord's acceptance of the payment of rent after the occurrence of any event of default) shall operate as a waver of any right to be paid a late charge or of any other right or remedy which the either party hereto would otherwise have against the other party on account of such event of default under the provisions of this Lease or applicable law (each party hereto hereby acknowledging that, in the interest of maintenance of good relations between Landlord and Tenant, there may be instances in which the other party chooses not immediately to exercise some or all of its rights on the occurrence of an event of default).

In The event that it shall become necessary for either Landlord or Tenant to employ the services of attorneys to enforce any of their respective rights under this Lease or to collect any sums due to them under this Lease or to remedy the breach of any covenant of this Lease on the part of the other to be kept or performed, the nonprevailing party (Tenant or Landlord as the case may be) shall pay to the prevailng party such reasonable fees as shall be charged by the prevailing party's attorneys for such services, including services at all trial and appellate levels and post judgment proceedings and such prevailing party shall also have and recover from the nonprevailing party (Landlord or Tenant as the case may be) all other costs and expenses of such suit and any appeal thereof or with respect to any postjudgment proceedings.

W I T N E S S E T H:

1. Premises. Lessor, for and in consideration of the rents, covenants, agreements and stipulations hereinafter mentioned, reserved and contained to be paid, kept and performed by Lessor, has leased and rented and by these presents does lease and rent unto Lessee, and Lessee hereby agrees to lease and take upon the terms and conditions which hereinafter appear, the following described property (hereinafter called "premises"), to-wit;

2. Term. To have and to hold the same for a term beginning on the 1st day of November, 1999 and terminating at 12:00 Midnight on October 31, 2002, unless sooner terminated as hereinafter provided.

3. Rental. Lessee agrees to pay to Lessor promptly on the 1st day of each month in advance during the term of this lease a monthly rental of $12,365. Said monthly rental payments shall be payable to Lessor at such location as Lessor shall from time to time specify. If the rental is not received by the 10th day of the month, a 5% delinquency penalty is due.

Schedule 3.11(b)(i)

If Lessee fails to pay any of said utility bills or charges for garbage collection or other sanitary services, Lessor may pay the same; and such payment may be added to the rental of the premises next due as additional rent.

5. Use of the Premises. Premises shall be used for General office space and/or Laboratory/Medical Facility purposes and no other. Premises shall not be used for any illegal purposes nor in any manner to create any nuisance or trespass nor in any manner to vitiate the insurance or increase the rate of insurance on premiums.

6. Abandonment of Leased Premises. Lessee agrees not to abandon or vacate the leased premises during the period of this lease and agrees to use said premises for the purposes herein leased until the expiration hereof.

7. Repairs by Lessor. Lessor agrees to keep in good repair the roof, foundations and exterior walls of the premises (exclusive of all glass and exclusive of all exterior doors) and underground utility and sewer pipes outside the exterior walls of the building, except repairs rendered necessary by the negligence of Lessee or Lessee's agents, employees or invitees. Lessor gives Lessee exclusive control over the premises and shall be under no obligation to inspect said premises. Lessee shall promptly report in writing to Lessor any defective condition known to Lessee which Lessor is required to repair; and failure to so

-2-

report such defects shall make Lessee responsible to Lessor for any liability incurred by Lessor by reason of such defects.

If Lessor does not within 45 days of written request by Lessee, make required repairs, Lessee may contract to have such repairs made, provided any repairs exceeding $7,500 may not be made without Lessor's express written consent. If Lessor does not pay for such repairs upon presentment of an invoice after completion of the repairs, Lessee may set-off such amounts against Lessee's rent obligations.

8. Repairs by Lessee. Lessee accepts the leased premises in their present condition and as suited for the uses intended by Lessee. Lessee shall, throughout the initial term of this lease and all renewals hereof, at Lessee's expense, maintain in good order and repair the leased premises, including the building and other improvements located thereon except those repairs expressly required to be made by Lessor. Lessee further agrees to care for the grounds around the building, including the mowing of grass, paving, care of shrubs and general landscaping. Lessee agrees to return said premises to Lessor at the expiration of prior to termination of this lease in as good condition and repair as when first received, natural wear and tear, damage by storm, fire, lighting, earthquake or other casualty alone excepted. Elevators, if any, are accepted by Lessee as in satisfactory operating condition on this date; and Lessee shall, as Lessee's own expense, maintain said elevators in good operating condition during the term of this lease and any extensions hereof.

9.1 Taxes and Association Fee. Lessee shall pay as additional rental during the term of this lease and any extension or renewal thereof, the association fees and the taxes (including but not limited to ad valorem taxes, special assessments and any other governmental charges) attributable to the premises for each tax year. In the event the premises are less than the entire property, the association fee and taxes for any such year applicable to the premises shall be determined by proration on the basis that the rental floor area of the premises bears to the total rentable floor area of the entire property. Lessee's pro rata portion of the association fee and taxes, as provided herein, shall be payable on a monthly basis based upon the prior year's actual association fees or taxes. Such estimated amounts shall be adjusted annually.

-3-

9.2 Insurance. Lessee shall, upon demand, pay as additional rental during the term of this lease and any extension or renewal thereof the property and casualty insurance on the premises for each tax year.

9.3 Mutual Waiver of Subrogation. The Landlord agrees that he will have inserted in each property and casualty policy or policies of insurance, which he may be required to carry (if any), a provision substantially as follows: "It is hereby stipulated that this insurance shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for loss occurring to the property described herein" and Landlord hereby waives, during the term of this lease, any or all rights of recovery against the Tenant, its officers, employees, and agents for loss occurring to the premises to the extent that indemnification would be due under such insurance protection.

Likewise, the Tenant agrees that he will have inserted in each property and casualty policy or policies of insurance, which it may be required to carry, (if any), a provision substantially as follows: "It is hereby stipulated that this insurance shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for loss occurring to the property described herein" and Tenant does hereby waive, during the term of this Lease, any and all rights of recovery against the Landlord, its officers, employees, and agents to the extent that indemnification would be due under such insurance protection.

10. Destruction of or Damages to Premises. If premises are totally destroyed by storm, fire, lightning, earthquake or other casualty, this lease shall terminate as of the date of such destruction; and rental shall be accounted for as between Lessor and Lessee as of that date. If premises are damaged but not wholly destroyed by any such casualties, rental shall abate in such proportion as use of the premises has been destroyed; and Lessor shall restore premises to substantially the same condition as before damage as speedily as practicable, whereupon full rental shall recommence.

Notwithstanding the foregoing, if Lessor has not within 6 months restored the premises to substantially the same condition as before damage, the Lessee may terminate this lease without being treated as in default.

-4-

11.1 Indemnity. Lessee agrees to indemnify and save harmless Lessor against all claims for damages to persons or property by reason of the use or occupancy of the leased premises and all expenses incurred by Lessor because thereof, including reasonable attorney's fees and court costs.

11.2 Indemnity. Lessor agrees to indemnify and save harmless Lessee against all claims for damages to persons or property by reason of the use or occupancy by Lessor or Lessor's agents of the leased premises and all expenses incurred by Lessee because thereof, including reasonable attorney's fees and court costs.

12. Governmental Orders. Lessee agrees, at Lessee's own expense, to promptly comply with all requirements of any legally constituted public authority made necessary by reason of Lessee's occupancy of said premises. Lessor agrees to promptly comply with any such requirements if not made necessary by reason of Lessee's occupancy. However, it is mutually agreed between Lessor and Lessee that, if in order to comply with such requirements, the cost to Lessor or Lessee, as the case may be, shall exceed a sum equal to one year's rent, then Lessor or Lessee who is obligated to comply with such requirements is privileged to terminate this lease by giving written notice of termination to the other party via Certified Mail, Return Receipt Requested, which termination shall become effective sixty (60) days after receipt of such notice and which notice shall eliminate the necessity of compliance with such requirement by party giving such notice unless the party receiving such notice of termination shall, before such termination becomes effective, pays to the party giving notice all costs of compliance in excess of one year's rent or secures the payment of said sum in a manner satisfactory to the party giving notice.

13. Condemnation. If the whole of the leased premises or such portion thereof as will make the premises unusable for the purposes herein leased shall be condemned by any legally constituted authority for any public use or purpose, then in either of said events the term hereby granted shall cease from the date when possession thereof is taken by public authorities; and rental shall be accounted for as between Lessor and Lessee as of said date. Such termination, however, shall be without prejudice to the rights of either Lessor or Lessee to recover compensation and damage caused by condemnation from the condemnor. It is

-5-

further understood and agreed that neither Lessee nor Lessor shall have any rights in any award made to the other by any condemnation authority notwithstanding the termination of the lease as herein provided.

14. Assignment and Subletting. Lessee may sublease portions of the leased premises to others provided such sublessee's operation is a part of the general operation of Lessee and under the supervision and control of Lessee and provided such operation is within the purposes for such said premises shall be used. Except as provided in the preceding sentence, Lessee shall not assign this lease or any interest hereunder or sublet premises or any part thereof or permit the use of premises by any party other than Lessee without the prior written consent of Lessor (not to be unreasonably withheld) endorsed hereon. At the option of Lessor, Assignee or Lessee shall become directly liable to Lessee for all obligations of Lessee hereunder; but no sublease or assignment by Lessee shall relieve Lessee of any liability hereunder.

15. Removal of Fixtures. If Lessee is not in default under this lease, Lessee may remove all fixtures and equipment which Lessee owns, provided Lessee repair all damage to premises caused by such removal and provided that Lessee, at Lessee's expense, return the space to standard office space comparable to other office space within the leased premises.

16. Cancellation of Lease by Lessor. It is mutually agreed that, in the event Lessee shall default in the payment of rent, including additional rent herein reserved, when due and fails to cure said default within five (5) days after written notice thereof from Lessor; or if Lessee shall be in default in performing any of the terms or provisions of this lease other than the provision requiring the payment of rent and fails to cure such default within thirty (30) days after the date of receipt of written notice of default from Lessor; or if Lessee is adjudicated bankrupt; or if a permanent receiver is appointed for Lessee's property and such receiver is not removed within sixty (60) days after written notice form Lessor to Lessee to obtain such removal; or if, whether voluntarily or involuntarily, Lessee takes advantage of any debtor relief proceedings under any present or future law, whereby the rent or any part thereof is or is proposed to be reduced or payment thereof deferred; or if Lessee makes an assignment for the benefit of creditors; or if Lessee's effects should be levied upon or

attached under process against Lessee and not satisfied or dissolved within thirty (30) days after written notice from Lessor to Lessee to obtain satisfaction thereof; then and in any of said events, Lessor (at Lessor's option) may at once or within six (6) months thereafter (but only during continuance of such default or condition), terminate this lease by written notice to Lessee, whereupon this lease shall end. After an authorized assignment or subletting of the entire premises covered by this lease, the occurring of any of the foregoing defaults or events shall affect the lease only if caused by or happening to the assignee or sublessee. Any notice provided in this Paragraph may be given by Lessor or Lessor's Attorney. Upon such termination by Lessor, Lessee will at once surrender possession of the premises to Lessor and remove all of Lessee's effects therefrom; and Lessor may forthwith re-enter the premises, repossess same and remove all persons and effect therefrom using such force as may be necessary without being guilty of trespass, forcible entry, detainer or other tort.

17. Re-entry by Lessor. Lessor, as Lessee's agent, may (at Lessor's option), without terminating this lease upon Lessee's breaching this lease, enter upon and rent the premises at the best price obtainable by reasonable effort without advertisement and by private negotiations and for any term Lessor deems proper. Lessee shall be liable to Lessor for the deficiency, if any, between Lessee's rent hereunder and the price obtained by Lessor on reletting.

18. Exterior Signs. Lessee shall place no signs upon the outside walls or roof of the leased premises except with the written consent of Lessor. Any and all signs placed on the premises by Lessee shall be maintained in compliance with rules and regulations governing such signs; and Lessee shall be responsible to Lessor for any damages caused by installation, use or maintenance of said signs. Lessee agrees to repair all damage incident to the removal of said signs upon removal of same.

19. Entry for Carding. Etc.. Lessor may card premises "For Rent" or "For Sale" ninety (90) days before the termination of this lease. Lessor or his agents may enter the premises at reasonable hours to exhibit same to prospective purchasers or tenants and to make repairs required of Lessor under the terms hereof.

-7-

20. Effect of Termination of Lease. No termination of this lease prior to the normal ending thereof by lapse of time or otherwise shall affect Lessor's right to collect rent for the period prior to termination thereof.

21. Mortgagee's Rights. Lessee's rights shall be subject to any bona fide mortgage or deed to secure debt which is now or may hereafter be placed upon the premises by Lessor.

22. No Estate in Land. This lease shall create the relationship of landlord and tenant between the parties hereto; and no estate shall pass out of Lessor. Lessee has only a usufruct not subject to levy and sale and not assignable by Lessee except by Lessor's consent (not to be unreasonably withheld).

23. Holding Over. If Lessee remains in possession of premises after the expiration of the term hereof with Lessor's acquiescence an without any express agreement of the parties, Lessee shall be a tenant at will at the rental rate in effect at the end of this lease; and there shall be no renewal of this lease by operation of law.

24. Attorney's Fees and Homestead. If any rent owing under this lease is collected by or through an attorney at law, Lessee agrees to pay reasonable attorney's fees incurred by Lessor. Lessee waives all homestead rights and exemptions which Lessee may have under the law as against any obligation owing under this lease. Lessee hereby assigns to Lessor all Lessee's homestead and exemption.

25. Rights Cumulative. All rights, powers and privileges conferred hereunder upon parties hereto shall be cumulative but not restrictive to those given by law.

26. Service of Notice. Lessee hereby appoints as Lessee's agent to receive service of all dispossessory or distraint proceedings and notices hereunder and all notices required under this lease, the person in charge of the leased premises at the time or the person occupying said premises, and if no person is in charge of or occupying said premises, then such service or notice may be made by attaching the same on the main entrance to said

-8-

premises. A copy of all notices under this lease shall also be sent to Lessee's last-known address if different from said premises.

27. Waiver of Rights. No failure of Lessor to exercise any power given Lessor hereunder or to insist upon strict compliance by Lessee with Lessee's obligations hereunder and no custom or practice of the parties at variance with the terms hereof shall constitute a waiver of Lessor's right to demand exact compliance with the terms hereof.

28. Time of Essence. Time is of the essence of this lease agreement.

29. Definitions. "Lessor" as used herein shall include first party and first party's heirs, representatives, assigns, and successors in title to the premises. "Lessee" shall include second party and second party's heirs and representatives and, if this lease shall be validly assigned or sublet, shall include also Lessee assignees or sublessees as to the premises covered by such assignment or sublease. "Lessor" and "Lessee" shall include male and female, singular and plural, corporation, partnership or individual as may fit the particular parties.

30. Security Deposit. Upon execution of this lease, Lessee shall pay a security deposit in the amount of Twelve Thousand Three Hundred Sixty-Five Dollars ($12,365.00) to Lessor. Upon termination of this lease and surrender of the premises by Lessee to Lessor, the security deposit shall be returned to Lessee, provided that Lessor may hold the security deposit for a period of thirty (30) days following surrender of possession and may deduct from the amount refunded any rental due and payable, the costs of repairing any damage or replacing any damaged portion of the premises and costs of cleaning the premises if Lessee fails to do so prior to surrender of possession.

Exhibit 10.13

EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into by and between REGENERATION TECHNOLOGIES, INC., a Florida corporation (the "Corporation") and JAMES M. GROOMS ("Employee").

WHEREAS, the Corporation is engaged in the business of manufacturing products from human and animal tissue in Alachua, Florida; and

WHEREAS, the Corporation desires to employ Employee and Employee desires to accept such employment during the term of this Agreement and upon the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual promises and the benefits accruing to the parties hereto, the parties agree as follows:

1. Employment. The Corporation hereby agrees to employ Employee, and Employee hereby agrees to accept such employment, to render services on behalf of the Corporation as Chief Executive Officer and President. The duties of Employee shall be those established by the Corporation's Board of Directors from time to time.

2. Devotion to Employment. During the term of this Agreement, Employee shall devote his full time on behalf of the Corporation, and he shall not engage in any other gainful employment without the written consent of the Corporation; provided, however, that nothing contained herein shall prohibit Employee from investing or trading in stocks, bonds, commodities or other forms of investment, including real property.


3. Term of Agreement. This Agreement shall be effective as of February 9, 1998, and it shall continue in full force and effect for a period of five (5) years unless sooner terminated as hereinafter provided.

4. Compensation.

(a) Annual Salary. The Corporation shall pay to Employee as compensation for his services a salary of One Hundred Ninety-Two Thousand Three Hundred Ninety-Five Dollars ($192,395.00) per year, payable in equal monthly installments. Employee's salary shall be reviewed annually by the Corporation's Board of Directors, at which time Employee's salary may be adjusted as agreed upon by Corporation's Board of Directors.

(b) Performance Bonus. To provide greater incentive for Employee by rewarding him with additional compensation, a cash bonus may be paid to Employee at any time during the year, or after the close of the year, based upon the performance of the Corporation and the performance of Employee during such year; provided, however, that the payment of any such bonus and the amount thereof shall be within the sole discretion of the Corporation's Board of Directors. In making such determination, the Directors will consider the following:

(i) The net profits of the Corporation for the year;

(ii) The base salary of Employee;

(iii) Employee's overall performance as an employee of the Corporation;

(iv) A comparison of Employee's performance with the performance of the other employees of the Corporation; and

-2-

(v) Such other matters as may be considered appropriate by the Directors.

(c) Withholding, FICA, FUTA. Employee's compensation hereunder shall be subject to, and reduced by, applicable federal income tax withholding and FICA tax, and any other taxes imposed by law.

5. Fringe Benefits. During the term of this Agreement, Employee shall be entitled to all fringe benefits offered generally to the Corporation's managerial employees as established or modified from time to time by the Corporation, subject always to the rules in effect regarding participation in such plans. In addition, the Corporation shall obtain and maintain in force during the term of this Agreement a life insurance policy covering Employee's life in a face value of not less than one million dollars ($1,000,000.00). The death benefit of such policy shall be made payable to the beneficiary or beneficiaries Employee may from time to time designate in writing.

6. Business Expenses. Except as otherwise provided herein, the Corporation shall pay, either directly or by reimbursement to Employee, such reasonable and necessary business expenses incurred by him, in the course of his employment by the Corporation as are consistent with the Corporation's policies in existence from time to time, subject to such dollar limitations and verification and record keeping requirements as may be established from time to time by the Corporation.

7. Vacation Time. Employee shall be entitled to four (4) weeks paid vacation time each calendar year, prorated in accordance with Corporation policy. All vacations shall be taken by Employee at such time or times as may be approved by the Corporation. There

-3-

will be no carryover of unused vacation time from one year to another, and no compensation for such unused vacation or sick leave, if any.

8. Time Off. Employee shall be entitled to such time off with pay for attendance at seminars, courses, meetings and conventions as is authorized by the Corporation from time to time. The specific seminars, courses, meetings and conventions to be attended by Employee shall be subject to the Corporation's prior approval.

9. Automobile. Employee shall provide an automobile for his use in the conduct of the Corporation's business as a condition of his employment. During the term of this Agreement, the Corporation shall reimburse Employee for Employee's use of his automobile and all incidental costs associated therewith (including, but not limited to, gas, oil, repairs, maintenance, insurance and car telephone) in the conduct of the Corporation's business based upon the standard mileage rate as announced from time to time by the Internal Revenue Service for use in computing deductible costs for operating a passenger automobile; provided, however, Employee shall be required to submit written verification to the Corporation of the mileage, destination and purpose of each trip for which reimbursement is requested pursuant to this Paragraph

10. Termination of Employment.

(a) Voluntary Termination. Employee or the Corporation may voluntarily terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) at any time, by delivering to the other party written notice of such intention not less than thirty (30) days prior to the effective date of termination. Notwithstanding the foregoing, if notice of termination is given by Employee to the Corporation, then the Corporation shall have the option of advancing the effective date of such

-4-

termination to any date after receipt of such notice from Employee, which option shall be exercised by the Corporation within three (3) business days of receipt of such notice.

(b) Termination for Cause. The Corporation may immediately terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) for "cause" by giving written notice (without regard to the thirty (30) day period provided above) of such termination to Employee specifying the grounds therefor. A termination for "cause" shall only be for any one or more of the following reasons:

(i) Willfully or negligently damaging the Corporation's property, business, reputation or goodwill.

(ii) Willfully injuring any employee of the Corporation.

(iii) Willfully injuring any person in the course of the performance of services for the Corporation.

(iv) Lawfully charged with commission of a felony.

(v) Stealing, dishonesty, fraud or embezzlement.

(vi) Deliberate and continuous neglect of duty.

(vii) Use of alcohol or narcotics to the extent it prevents, in the sole judgment of the Corporation's Board of Directors, Employee from effectively performing the duties set forth in Paragraph 1 above.

(viii) Violating the covenants set forth in Paragraphs 11 or 12 of this Agreement.

The decision to terminate Employee's employment for "cause" shall be made by the Corporation's Board of Directors in its sole discretion.

-5-

(c) Termination Upon Death, Incompetency or Disability. Notwithstanding Subparagraph 10(a) above, the Corporation shall have the right to terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) immediately and without prior written notice to Employee in the event that Employee dies or is adjudicated incompetent, or is "permanently disabled" as hereinafter defined. As used herein, the term "permanently disabled" shall mean that Employee is unable to adequately perform his regular duties hereunder as a result of sickness or accident and such condition appears to be permanent. The determination of "permanent disability" shall be made by the Corporation's Board of Directors in its sole and absolute discretion and its decision shall be final and binding on Employee unless found to be arbitrary or capricious by a court of competent jurisdiction.

(d) Performance of Duties During Notice Period. In the event that either party terminates Employee's employment with the Corporation in accordance with the terms of Subparagraph 10(a), Employee, if requested by the Corporation, shall continue to render services hereunder on behalf of the Corporation for the thirty (30) day period until the effective date of termination, and shall, in such event, be paid the compensation due him hereunder for the remainder of such period.

11. Confidential Information. Employee acknowledges and recognizes that, in connection with the performance of his duties and obligations for the Corporation, Employee has and will have access to certain confidential information of the Corporation, including, but not limited to, any intellectual property of the Corporation, the identity of the Corporation's clients,

-6-

the identity of prospective clients, the existence of negotiations with prospective clients of the Corporation, all drawings, records, sketches, models, financial information, customer information, trade secrets, and trade secrets relating to services of the Corporation, and products being developed by the Corporation (the "Confidential Information"). Employee hereby acknowledges that the maintenance of the confidentiality of the Confidential Information and restrictions on the use of the Confidential Information is essential to the Corporation. Employee shall not, at any time, whether during the term of this Agreement or after the termination of Employee's employment with the Corporation for any reason whatsoever, divulge or reveal any of the Confidential Information to any person, party or entity, directly or indirectly. In addition, Employee shall not utilize any of the Confidential Information for his own benefit, for the benefit of any subsequent employer or competitor of the Corporation. Employee shall maintain the Confidential Information in strict confidence and shall not copy, duplicate or otherwise reproduce, in whole or in part, such Confidential Information, except as necessary for Employee to perform services for the Corporation. Upon the termination of Employee's employment by the Corporation, or at the earlier request of the Corporation, Employee shall immediately surrender to the Corporation any and all memoranda, records, files or other documents and any other materials (including photocopies or other reproductions) containing or relating to the Confidential Information. Employee shall indemnify and hold the Corporation harmless from any loss, damage, expense, cost or liability arising out of any unauthorized use or disclosure of the Confidential Information by Employee. The provisions of this Paragraph 11 shall survive the termination of Employee's employment with the Corporation and the termination of this Agreement.

-7-

12. Employee Developments. Employee is aware and understands that, during the term of Employee's employment with the Corporation or with the financial and other assistance that may be provided by the Corporation, Employee may invent, create, develop and improve certain valuable property such as, but not limited to, patents, trademarks, inventions, other patentable inventions and other trade secrets and formula, where such valuable property is (1) created during Employee's normal work hours; (2) created using the equipment or facilities of the Corporation; (3) created by Employee under the supervision or guidance of the Corporation; or (4) within the field of use which includes human or animal allograft tissue ("Employee Developments"). Employee agrees that all Employee Developments that may be developed or produced by Employee during Employee's employment by the Corporation are and will be the property of the Corporation, and that Employee further agrees that he will, at the request of the Corporation, execute such documents as the Corporation may reasonably request from time to time, to assign and transfer all of the right, title and interest in Employee Developments that are the property of the Corporation to the Corporation and he will cooperate with the Corporation in connection with any patent applications. In this regard, Employee will, at all times, fully advise and inform the Corporation of all matters that Employee may be developing or working on while employed by the Corporation. Employee further agrees that upon the termination of his employment with the Corporation for any reason whatsoever, he shall immediately deliver and surrender to the Corporation any and all plans, documents and other materials of any nature relating to Employee Developments. The Corporation may provide additional compensation to Employee as consideration for Employee Developments in

-8-

accordance with any patent policy of the Corporation. The provisions of this Paragraph 12 shall survive the termination of this Agreement.

13. Limitation of Employment.

(a) In the event of the termination of Employee's employment with the Corporation by the Corporation for cause (as defined in Subparagraph 10(b) above), Employee agrees that for a period of one (1) year following the effective date of such termination, he will not engage in any business which receives, processes, or distributes human tissue within the United States. In the event of the termination of Employee's employment with the Corporation by the Corporation without cause, Employee agrees that for a period of one (1) year following the effective date of such termination, Employee will not engage in any business which receives, processes, or distributes human tissue (or in any business that competes with the Corporation) within the United States; provided, however, that Employee shall then be entitled to a severance payment in the amount of one (1) times his then-current salary (computed without reference to shares of stock in the Corporation, fringe benefits, or any other form of compensation). The Corporation may require Employee to execute a release of claims against the Corporation as a condition precedent to its obligation to make the severance payment described herein.

(b) Employee acknowledges that this restrictive covenant is reasonably necessary to protect the Corporation's legitimate business interests, which are represented by, among other things, the substantial relationships between the Corporation and its licensees and tissue sources, as well as the goodwill established by the Corporation with licensees and tissue sources in the United States and other countries where the Corporation's products are manufactured or distributed over a protracted period.

-9-

(c) Employee recognizes the fact that the Corporation would not sign this Agreement without the inclusion of this covenant, and Employee confirms the sufficiency of the consideration received by him, in the form of employment by the Corporation, in accepting this covenant as a material term of the Agreement.

(d) The period set forth in subparagraph (a) above will be tolled during any time in which Employee is in violation of the restrictive covenant contained in this Paragraph 13, and that period will begin to run again from the date Employee ceases such violation.

(e) This Paragraph 13 will survive the termination of this Agreement and the termination of Employee's employment with the Corporation.

14. Remedies For Breach. The parties understand and agree that no amount of money would adequately compensate the Corporation for damages which the parties acknowledge would be suffered as a result of a violation by Employee of the covenants contained in Paragraphs 11, 12 or 13 above, and that, therefore, the Corporation shall be entitled, upon application to a court of competent jurisdiction, to obtain injunctive relief to enforce the provisions of Paragraphs 11, 12 and/or 13, which injunctive relief shall be in addition to any other rights or remedies available to the Corporation. If such a violation occurs, Employee shall be responsible for the payment of reasonable attorney's fees and other costs and expenses incurred by the Corporation in enforcing the covenants contained in Paragraphs 11, 12 and/or 13 above, whether incurred at the trial level or in any appellate proceeding. The provisions of this Paragraph 14 shall survive the termination of this Agreement.

-10-

15. Limitations on Authority. Without the express written consent of the Corporation's Board of Directors, Employee shall have no authority to do any of the following:

(a) Pledge the credit of the Corporation or any of its other employees;

(b) Bind the Corporation under any contract, agreement, note, mortgage or other obligation, except as provided in the Corporation's Standard Operating Procedures;

(c) Release or discharge any debt due the Corporation unless the Corporation has received the full amount thereof; or

(d) Sell, mortgage, transfer or otherwise dispose of any assets of the Corporation.

Notwithstanding the foregoing, Employee may bind the Corporation under contracts, agreements, notes, mortgages or other obligations up to a value of $100,000, provided the approval and signature of either the Corporation's Chief Operating Officer or Chief Financial Officer is also obtained with respect to same.

16. Severability. If any provision of this Agreement shall be declared invalid or unenforceable by a court of competent jurisdiction, the invalidity or unenforceability of such provision shall not affect the other provisions hereof, and this Agreement shall be construed and enforced in all respects as if such invalid or unenforceable provision was omitted.

17. Attorney's Fees and Costs. Except as provided in Paragraph 14 above, in the event a dispute arises between the parties hereto and suit is instituted, the prevailing party in such litigation shall be entitled to recover reasonable attorney's fees and other costs and expenses from the nonprevailing party, whether incurred at the trial level or in any appellate proceeding.

-11-

18. Governing Law; Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of Florida, and venue for any legal proceeding or action at law arising out of or construing this Agreement shall lie in the state courts of Alachua County, Florida, or the United States District Court for the Northern District of Florida, Gainesville Division.

19. Completeness of Agreement. All understandings and agreements heretofore made between the parties hereto with respect to the subject matter of this Agreement are merged into this document which alone fully and completely expresses their agreement. No change or modification may be made to this Agreement except by instrument in writing duly executed by the parties hereto with the same formalities as this document.

In addition, Employee shall not utilize any of the Confidential Information for Employee's own benefit, or for the benefit of any subsequent employer or competitor of the Corporation. Employee shall maintain the Confidential Information in strict confidence and shall not copy, duplicate or otherwise reproduce, in whole or in part, such Confidential Information, except as necessary for Employee to perform services for the Corporation. Upon the termination of Employee's employment by the Corporation, or at the earlier request of the Corporation, Employee shall immediately surrender to the Corporation any and all memoranda, records, files or other documents and any other materials (including photocopies or other reproductions) containing or relating to the Confidential Information. Employee shall indemnify and hold the Corporation harmless from any loss, damage, expense, cost or liability arising out of any unauthorized use or disclosure of the Confidential Information by Employee. The provisions of this Paragraph 10 shall survive the termination of Employee's employment with the Corporation and the termination of this Agreement.

11. Employee Developments. Employee is aware and understands that, during the term of Employee's employment with the Corporation or with the financial and other assistance that may be provided by the Corporation, Employee may invent, create, develop and improve certain valuable property such as, but not limited to, patents, trademarks, inventions, other patentable inventions and other trade secrets and formula, where such valuable property is (1) created during Employee's normal work hours; (2) created using the equipment or facilities

In this regard, Employee will, at all times, fully advise and inform the Corporation of all matters that Employee may be developing or working on while employed by the Corporation. Employee further agrees that upon the termination of his employment with the Corporation for any reason whatsoever, Employee shall immediately deliver and surrender to the Corporation any and all plans, documents and other materials of any nature relating to the Employee Developments. The Corporation may provide additional compensation to Employee as consideration for Employee Developments in accordance with any patent policy of the Corporation. The provisions of this Paragraph 11 shall survive the termination of this Agreement.

12. Limitation of Employment.

(a) In the event of the termination of Employee's employment with the Corporation either by the Corporation for cause (as defined in Subparagraph 9(b) above) or voluntarily by Employee, Employee agrees that for a period of two (2) years following the

- 8 -

effective date of such termination, Employee will not engage in the tissue banking business (or in any business that competes with Corporation) within the Southeastern United States. In the event of the termination of Employee's employment with the Corporation by the Corporation without cause, Employee agrees that for a period of one (1) year following the effective date of such termination, Employee will not engage in the tissue banking business (or in any business that competes with such business) within the Southeastern United States.

(b) Employee acknowledges that this restrictive covenant is reasonably necessary to protect the Corporation's legitimate business interests, which are represented by, among other things, the substantial relationships between the Corporation and its licensees and tissue sources, as well as the goodwill established by the Corporation with licensees and tissue sources in the United States and other countries where the Corporation's tissues are distributed over a protracted period.

(d) The parties acknowledge and agree that no amount of money would adequately compensate the Corporation for damages which the parties acknowledge would be suffered as a result of the violation of the terms of this provision by Employee, and they confirm that any such violation would result in irreparable injury to the Corporation because

- 9 -

of the reduction in its income caused by the loss of or damage to the aforesaid relationships. It is agreed that the Corporation will be entitled to specific performance of this provision, and to injunctive relief, in view of the fact that the actual harm is not readily ascertainable or compensable by money damages.

(e) The period set forth in subparagraph (a) above will be tolled during any time in which Employee is in violation of the restrictive covenant contained in this Paragraph 12, and that period will begin to run again from the date Employee ceases such violation.

(f) This Paragraph 12 will survive the termination of this Agreement and the termination of Employee's employment with the Corporation.

13. Remedies For Breach. It is understood and agreed by the parties that no amount of money would adequately compensate the Corporation for damages which the parties acknowledge would be suffered as a result of a violation by the Employee of the covenants contained in Paragraphs 10, 11 and 12 above, and that, therefore, the Corporation shall be entitled, upon application to a court of competent jurisdiction, to obtain injunctive relief to enforce the provisions of Paragraphs 10, 11 and 12, which injunctive relief shall be in addition to any other rights or remedies available to the Corporation. If such a violation occurs, Employee shall be responsible for the payment of reasonable attorney's fees and other costs and expenses incurred by the Corporation in enforcing the covenants contained in Paragraphs 10, 11 and 12 above, whether incurred at the trial level or in any appellate proceeding. The provisions of this Paragraph 13 shall survive the termination of this Agreement.

Notwithstanding the foregoing, Employee may bind the Corporation under contracts, agreements, notes, mortgages or other obligations up to a value of $500,000, provided the approval and signature of either the Corporation's President or Chief Operating Officer is also obtained with respect to same.

15. Severability. If any provision of this Agreement shall be declared invalid or unenforceable by a court of competent jurisdiction, the invalidity or unenforceability of such provision shall not affect the other provisions hereof, and this Agreement shall be construed and enforced in all respects as if such invalid or unenforceable provision was omitted.

16. Attorney's Fees and Costs. Except as provided in Paragraph 13 above, in the event a dispute arises between the parties hereto and suit is instituted, the prevailing party in such litigation shall be entitled to recover reasonable attorney's fees and other costs and expenses from the nonprevailing party, whether incurred at the trial level or in any appellate proceeding.

If such a violation occurs, Employee shall be responsible for the payment of reasonable attorney's fees and other costs and expenses incurred by the Corporation in enforcing the covenants contained in Paragraphs 12 and 13 above, whether

(d) Sell, mortgage, transfer or otherwise dispose of any assets of the Corporation.

17. Attorney's Fees and Costs. Except as provided in Paragraph 14 above, in the event a dispute arises between the parties hereto and suit is instituted, the prevailing party in such litigation shall be entitled to recover reasonable attorney's fees and other costs and expenses from the nonprevailing party, whether incurred at the trial level or in any appellate proceeding.

EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into this 15th day of June, 1998, by and between REGENERATION TECHNOLOGIES, INC., a Florida corporation (the "Corporation") and THOMAS BREWER ("Employee").

WHEREAS, the Corporation is engaged in the business of manufacturing products from bone tissue in Alachua, Florida; and

WHEREAS, the Corporation desires to employ Employee and Employee desires to accept such employment during the term of this Agreement and upon the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual promises and the benefits accruing to the parties hereto, the parties agree as follows:

1. Employment. The Corporation hereby agrees to employ Employee, and Employee hereby agrees to accept such employment, to render services on behalf of the Corporation as Director of Marketing. The duties of Employee shall be those established by the Corporation's Board of Directors, or its officers, from time to time.

2. Devotion to Employment. During the term of this Agreement, Employee shall devote his full time on behalf of the Corporation, and Employee shall not engage in any other gainful employment without the written consent of the Corporation. Provided, however, that nothing contained herein shall prohibit Employee from investing or trading in stocks, bonds, commodities or other forms of investment, including real property.


3. Term of Agreement. This Agreement shall be effective as of the date first written above, and it shall continue in full force and effect for a period of five (5) years unless sooner terminated as hereinafter provided.

4. Compensation.

(a) Annual Salary. The Corporation shall pay to Employee as compensation for his services a salary of One Hundred Forty-Eight Thousand Dollars ($148,000.00) per year, payable in equal biweekly installments. Employee's salary shall be reviewed annually by the Corporation's Board of Directors, at which time Employee's salary may be adjusted as mutually agreed upon by Employee and the Corporation's Board of Directors.

(b) Performance Bonus. To provide greater incentive for Employee by rewarding him with additional compensation, a cash bonus may be paid to Employee at any time during the year, or after the close of the year, based upon the performance of the Corporation and the performance of Employee during such year; provided, however, that the payment of any such bonus and the amount thereof shall be within the sole discretion of the Corporation's Board of Directors. In making such determination, the Directors will consider the following:

(i) The net profits of the Corporation for the year;

(ii) The base salary of Employee;

(iii) Employee's overall performance as an employee of the Corporation;

-2-

(iv) A comparison of Employee's performance with the performance of the other employees of the Corporation; and

(v) Such other matters as may be considered appropriate by the Directors.

The performance bonus described herein, if any, shall not exceed twenty percent (20%) of Employee's base annual salary.

(c) Stock of the Corporation. The Corporation shall issue to Employee the option to purchase Forty-Five Thousand (45,000) shares of common stock of the Corporation (the "Shares") at a price and on the terms set forth in the "Regeneration Technologies, Inc. Omnibus Stock Plan." The Shares shall be issued as described therein only upon Employee's execution of a Stock Restriction Agreement for Regeneration Technologies, Inc. (the "Stock Restriction Agreement"), which, inter alia restricts the transfer of the Shares and contains certain buy-back provisions regarding the Shares upon the termination of Employee's employment with the Corporation.

(d) Withholding, FICA, FUTA. Employee's salary and performance bonus, if any, shall be subject to, and reduced by, applicable federal income tax withholding and FICA tax, and any other taxes imposed by law.

5. Fringe Benefits. During the term of this Agreement, Employee shall be entitled to all fringe benefits offered generally to the Corporation's managerial employees as established or modified from time to time by the Corporation, subject always to the rules in effect regarding participation in such plans. Notwithstanding the foregoing, Employee shall not be entitled to receive health insurance, life insurance, or long term disability insurance

-3-

until the three month waiting period, commencing on Employee's first day of performance hereunder, has expired. During such three month waiting period, the Corporation shall reimburse Employee for his actual out-of-pocket expenses incurred in maintaining his pre-existing health, life, and long term disability coverages, if any. Employee shall not be entitled to any other fringe benefits as a result of his employment with the Corporation.

6. Business Expenses. Except as otherwise provided herein, the Corporation shall pay, either directly or by reimbursement to Employee, such reasonable and necessary business expenses incurred by Employee in the course of his employment by the Corporation as are consistent with the Corporation's policies in existence from time to time, subject to such dollar limitations and verification and record keeping requirements as may be established from time to time by the Corporation.

7. Vacation. Employee shall be entitled to four (4) weeks paid vacation time each calendar year, prorated in accordance with Corporation policy. All vacations shall be taken by Employee at such time or times as may be approved by the Corporation.

9. Termination of Employment.

-4-

(a) Voluntary Termination. Employee or the Corporation may voluntarily terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) at any time, by delivering to the other party written notice of such intention not less than thirty (30) days prior to the effective date of termination. Notwithstanding the foregoing, if notice of termination is given by Employee to the Corporation, then the Corporation shall have the option of advancing the effective date of such termination to any date after receipt of such notice from Employee, which option shall be exercised by the Corporation within three (3) business days of receipt of such notice.

(b) Termination for Cause. The Corporation may immediately terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) for "cause" by giving written notice (without regard to the thirty (30) day period provided above) of such termination to Employee specifying the grounds therefor. A termination for "cause" shall only be for any one or more of the following reasons:

(i) Willfully or negligently damaging the Corporation's property, business, reputation or goodwill.

(ii) Willfully injuring any employee of the Corporation.

(iii) Willfully injuring any person in the course of the performance of services for the Corporation.

(iv) Lawfully charged with commission of a felony.

(v) Stealing, dishonesty, fraud or embezzlement.

(vi) Deliberate and continuous neglect of duty.

-5-

(vii) Use of alcohol or narcotics to the extent it prevents, in the sole judgment of the Corporations Board of Directors, Employee from effectively performing the duties set forth in Paragraph 1 above.

The decision to terminate Employee's employment for "cause" shall be made by the Corporation's Board of Directors in its sole discretion.

(c) Termination Upon Death, Incompetency or Disability. Notwithstanding Subparagraph 9(a) above, the Corporation shall have the right to terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) immediately and without prior written notice to Employee in the event that Employee dies, or is adjudicated incompetent, or is "permanently disabled", as hereinafter defined. As used herein, the term "permanently disabled" shall mean that Employee is unable to adequately perform his regular duties hereunder as a result of sickness or accident and such condition appears to be permanent. The determination of "permanent disability" shall be made by the Corporation's Board of Directors in its sole and absolute discretion and its decision shall be final and binding on Employee unless found to be arbitrary or capricious by a court of competent jurisdiction.

(d) Performance of Duties During Notice Period. In the event that Employee terminates Employee's employment with the Corporation in accordance with the terms of Subparagraph 9(a), Employee, if requested by the Corporation, shall continue to render services hereunder on behalf of the Corporation for the thirty (30) day period until the

Employee shall not, at any time, whether during the term of this Agreement or after the termination of Employee's employment with the Corporation for any reason whatsoever, divulge or reveal any of the Confidential Information to any person, party or entity, directly or indirectly.

Employee shall maintain the Confidential Information in strict confidence and shall not copy, duplicate or otherwise reproduce, in whole or in part, such Confidential Information, except as necessary for Employee to perform services for the Corporation. Upon the termination of Employee's employment by the Corporation, or at the

-7-

earlier request of the Corporation, Employee shall immediately surrender to the Corporation any and all memoranda, records, files or other documents and any other materials (including photocopies or other reproductions) containing or relating to the Confidential Information. Employee shall indemnify and hold the Corporation harmless from any loss, damage, expense, cost or liability arising out of any unauthorized use or disclosure of the Confidential Information by Employee. The provisions of this Paragraph 10 shall survive the termination of Employee's employment with the Corporation and the termination of this Agreement.

11. Employee Developments. Employee is aware and understands that, during the term of Employee's employment with the Corporation or with the financial and other assistance that may be provided by the Corporation, Employee may invent, create, develop and improve certain valuable property such as, but not limited to, patents, trademarks, inventions, other patentable inventions and other trade secrets and formula, where such valuable property is (1) created during Employee's normal work hours; (2) created using the equipment or facilities of the Corporation; (3) created by Employee under the supervision or guidance of the Corporation; or (4) within the field of use which includes human or animal allograft tissue ("Employee Developments").

In this regard,

-8-

Employee will, at all times, fully advise and inform the Corporation of all matters that Employee may be developing or working on while employed by the Corporation. Employee further agrees that upon the termination of his employment with the Corporation for any reason whatsoever, Employee shall immediately deliver and surrender to the Corporation any and all plans, documents and other materials of any nature relating to the Employee Developments. The Corporation may provide additional compensation to Employee as consideration for Employee Developments in accordance with any patent policy of the Corporation. The provisions of this Paragraph 11 shall survive the termination of this Agreement.

12. Limitation of Employment.

(a) After nine months of performance hereunder, in the event of the termination of Employee's employment with the Corporation either by the Corporation for cause (as defined in Subparagraph 9(b) above) or voluntarily by Employee, Employee agrees that for a period of two (2) years following the effective date of such termination, Employee will not engage in any business which receives, processes, or distributes human tissue (or in any business that competes with the Corporation) within the United States.

The

-9-

Corporation may require Employee to execute a release of claims against the Corporation as a condition precedent to its obligation to make the severance payment described herein.

(b) During the first nine months of performance hereunder, in the event of the termination of Employee's employment with the Corporation either by the Corporation for cause (as defined in Subparagraph 9(b) above) or voluntarily by Employee, Employee will not engage in the tissue banking business (or in any business that competes with the Corporation) within the United States, subject to the following terms:

Length of Service        Length of Noncompetition Period     Severance Amount
-----------------        -------------------------------     ----------------
0-3 months               none                                none

4-9 months               one month for each month of         none
                         service after the third month

Length of Service        Length of Noncompetition Period     Severance Amount
-----------------        -------------------------------     ----------------
0-3 months               none                                none

4-9 months               one month for each month of         none
                         service after the third month

-10-

The base salary described in this subparagraph shall be computed without reference to shares of stock in the Corporation, fringe benefits, or any other form of compensation. The Corporation may require Employee to execute a release of claims against the Corporation as a condition precedent to its obligation to make the severance payment described herein.

(c) Employee acknowledges that this restrictive covenant is reasonably necessary to protect the Corporation's legitimate business interests, which are represented by, among other things, the substantial relationships between the Corporation and its licensees and tissue sources, as well as the goodwill established by the Corporation with licensees and tissue sources in the United States and other countries where the Corporation's tissues are distributed over a protracted period.

(d) Employee recognizes the fact that the Corporation would not sign this Agreement without the inclusion of this covenant, and Employee confirms the sufficiency of the consideration received by Employee, in the form of employment by the Corporation, in accepting this covenant as a material term of the Agreement.

(e) The parties acknowledge and agree that no amount of money would adequately compensate the Corporation for damages which the parties acknowledge would be suffered as a result of the violation of the terms of this provision by Employee, and they confirm that any such violation would result in irreparable injury to the Corporation because of the reduction in its income caused by the loss of or damage to the aforesaid relationships.

Subj: Employment Agreement ICO James P. Abraham

the Corporation any and all plans, documents and other materials of any nature relating to the Employee Developments. The Corporation may provide additional compensation to Employee as consideration for Employee Developments in accordance with any patent policy of the Corporation. The provisions of this Paragraph 12 shall survive the termination of this Agreement.

13. Limitation of Employment.

(a) In the event of the termination of Employee's employment with the Corporation either by the Corporation for cause (as defined in Subparagraph 10(b) above) or voluntarily by Employee, Employee agrees that for a period of three (3) years following the effective date of such termination, Employee will not engage in or be employed by any business which engages in the business of manufacturing or distributing products from bone tissue in the United States.

(5) The Corporation provides Employee four (4) months of basic annual salary if Employee has served at least (09) months of employment upon termination, to be paid out monthly;

(7) The Corporation provides Employee six (6) months of basic annual salary if Employee has served at least (12) months of employment upon termination, to be paid out monthly.

(b) Employee acknowledges that this restrictive covenant is reasonably necessary to protect the Corporation's legitimate business interests, which are represented by, among other things, the substantial relationships between the Corporation and its licensees and tissue sources, as well as the goodwill established by the Corporation with licensees and tissue sources in the United States and other countries where the Corporation's tissues are distributed over a protracted period.

10

Subj: Employment Agreement ICO James P. Abraham

(c) Employee recognizes the fact that the Corporation would not sign this Agreement without the inclusion of this covenant, and Employee confirms the sufficiency of the consideration received by Employee, in the form of employment by the Corporation, in accepting this covenant as a material term of the Agreement.

(d) It is agreed that the Corporation will be entitled to specific performance of this provision, and to injunctive relief in view of the fact that the actual harm is not readily ascertainable or compensable by money damages.

(e) The period set forth in subparagraph (a) above will be tolled during any time in which Employee is in violation of the restrictive covenant contained in this Paragraph 13, and that period will begin to run again from the date Employee ceases such violation.

(f) This Paragraph 13 will survive the termination of this Agreement and the termination of Employee's employment with the Corporation.

14. Remedies For Breach. It is understood and agreed by the parties that no amount of money would adequately compensate the Corporation for damages which the parties acknowledge would be suffered as a result of a violation by the Employee of the covenants contained in Paragraphs 12 and 13 above, and that, therefore, the Corporation shall be entitled, upon application to a court of competent jurisdiction, to obtain injunctive relief to enforce the provisions of Paragraphs 12 and 13, which injunctive relief shall be in addition to any other rights or remedies available to the Corporation. If such a violation occurs, Employee shall be responsible for the payment of reasonable attorney's fees and other costs and expenses incurred by the Corporation in enforcing the covenants contained in Paragraphs 12 and 13 above, whether

11

Subj: Employment Agreement ICO James P. Abraham

incurred at the trial level or in any appellate proceeding. The provisions of this Paragraph 14 shall survive the termination of this Agreement.

15. Limitations on Authority. Without the express written consent of the Corporation's Board of Directors, Chief Executive Officer, or the Vice President of Business Development, Employee shall have no apparent or implied authority to do any of the following:

(a) Pledge the credit of the Corporation or any of its other employees;

(b) Bind the Corporation under any contract, agreement, note, mortgage or other obligation, except in the performance of his/her functional duties relating to Director, Sales and in conjunction with signature of CEO or VP of Business Development;

(c) Release or discharge any debt due the Corporation unless the Corporation has received the full amount thereof; or

(d) Sell, mortgage, transfer or otherwise dispose of any assets of the Corporation.

16. Subject to the terms and conditions set forth herein, RTI indemnifies Employee if Employee is made a party to any lawsuit initiated by Encore Orthopedics, Inc. ("Encore") which is based primarily on Employee taking employment with Regeneration Technologies, Inc. (RTI). This indemnification covers expenses (including attorneys' fees) actually and reasonably incurred by Employee in connection with the defense or settlement of such action. In the event that RTI has the obligation to indemnify Employee under this agreement, then RTI shall have the right to designate the counsel that will handle the litigation. RTI will not have a duty to provide indemnification if Employee has not fully disclosed to RTI his contractual obligations to RTI, or if Employee breaches any confidentiality arrangements

12

Subj: Employment Agreement ICO James P. Abraham

(contractual or otherwise) that he has with RTI. It is RTI's understanding that the only contractual obligation Employee has with Encore regarding employment with Encore or concerning obligations owed to Encore after his termination of employment with Encore is the Indemnification Agreement dated August 16, 1995, the Employment Agreement dated August 17, 1995, and the Severance Agreement dated September 19, 1995, between Employee and Encore. Employee must disclose to RTI and, prior to his commencement of employment with RTI, provide RTI with a copy of those agreements and any other agreements that he has with Encore.

As a condition of RTI's promise to indemnify Employee, Employee agrees not to take any actions that may be deemed by a reasonable person to breach any confidentiality agreements you have with Encore. These prohibited actions include, but are not limited to, making copies of internal, confidential lists of customers, sales agents or distributors of Encore, removing from Encore any property of Encore, or disclosing to any current or future employee of RTI any information that Employee knows to be a trade secret or protected confidential information of Encore. Employee's failure to fully comply with this condition will nullify RTI's obligation to indemnify Employee.

17. Severability. If any provision of this Agreement shall be declared invalid or unenforceable by a court of competent jurisdiction, the invalidity or unenforceability of such provision shall not affect the other provisions hereof, and this Agreement shall be construed and enforced in all respects as if such invalid or unenforceable provision was omitted.

18. Attorney's Fees and Costs. Except as provided in Paragraph 14 above, in

13

Subj: Employment Agreement ICO James P. Abraham

the event a dispute arises between the parties hereto and suit is instituted, the prevailing party in such litigation shall be entitled to recover reasonable attorney's fees and other costs and expenses from the nonprevailing party, whether incurred at the trial level or in any appellate proceeding.

19. Governing Law; Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of Florida, and venue for any legal proceeding or action at law arising out of or construing this Agreement shall lie in the state courts of Alachua County, Florida, or the United States District Court for the Northern District of Florida, Gainesville Division.

20. Completeness of Agreement. All understandings and agreements heretofore made between the parties hereto with respect to the subject matter of this Agreement are merged into this document which alone fully and completely expresses their agreement. No change or modification may be made to this Agreement except by instrument in writing duly executed by the parties hereto with the same formalities as this document.

Proposal for compensation for the position of V.P. Sales:

Salary: $175,000 per year

Car Allowance: $550 per month

Club Dues: Local golf course

Stock Options: 50,000 shares total

Year-End Bonus Program: 15% of salary based on Top Line Revenue achievement

10% of salary based on Profitability Performance

5% of salary based on Expense Budget Performance

Quarterly Override: .2% of sales from dollar one on all sports medicine and oral maxilliofacial products.


.02% of sales from dollar one on conventional tissue sales.

Presidents discretion: Bonus based on increase in all RTI direct products as a percentage of overall sales as Compared to SDG sales.

1) Salary is based on current salary as Director of sales of $150k per year and promotion to V.P. level. This figure is very consistent with salary ranges of vice presidents in the health care profession. This would be the current bottom of a range that caps around 5225K.
2) Car allowance is a perk of most sales executives that are entertaining clients. 3l cents per mile is much less cost effective. I currently have only utilized this mileage charge if I have traveled over 200 miles.
3) Club dues follow the same path as perks for sales executives. I have been informed tat we have been paying dues for certain executives at the Heritage club. It is more effective for us to have a membership at a golf club for entertaining surgeons and distributors.
4) Stock options bring me in line with other vice presidents and several directors. My original negotiations were based on outstanding stock of 2 million shares. The current outstanding stock is 4 million, this gives me just at 1% of current outstanding shares.
5) Bonus Program should reflect every Vice Presidents efforts to achieve revenue profitability and budget control. I would suggest that we make this a standard program for all of us and recognize this with stock options or profit sharing of some type.
6) The president should retain the ability to compensate sales and marketing executives with a discretionary bonus based on achievements. This is a personal goal to succeed at a faster rate than Danek.

I have the greatest ability of anyone in the company to affect sales and top line performance. My compensation is currently heavily weighted towards sales of all partner products. This seems to have been conceived in an attempt to justify getting me to an overall compensation dollar amount that we agreed upon for my hire of 100k in bonus. This is good for me, but may not be in the companies best interest.

My 1998 total W-2 was over $312,000. W-2 is available for your review. The current compensation structure is attached for your review. This new compensation structure enclosed should be very similar to the current compensation program with the addition of a salary raise.

Coming to work with RTI has been a great career move for me and my family. We are enjoying Gainesville and appreciate the confidence you have shown in promoting me to Vice President. We will be successful in developing the company into the market leader in Allograft\Xenograft tissue.

WHEREAS, the Corporation is engaged in the business of manufacturing products from human and animal tissue in Alachua, Florida; and

WHEREAS, the Corporation desires to employ Employee and Employee desires to accept such employment during the term of this Agreement and upon the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual promises and the benefits accruing to the parties hereto, the parties agree as follows:

1. Employment. The Corporation hereby agrees to employ Employee, and Employee hereby agrees to accept such employment, to render services on behalf of the Corporation as Vice President of Business Development. The duties of Employee shall be those established by the Corporation's Board of Directors, or its officers, from time to time.

2. Devotion to Employment. During the term of this Agreement, Employee shall devote approximately fifty percent (50%) of her time on behalf of the Corporation, it being understood and agreed between the Corporation and Employee that Employee shall devote the remaining fifty percent (50%) of her time on behalf of University of Florida Tissue Bank, Inc. ("Tissue Bank") and Employee shall not engage in any other gainful employment without the written consent of the Corporation. Provided, however, that nothing contained herein shall prohibit Employee from investing or trading in stocks, bonds, commodi-


ties or other forms of investment, including real property. Employee and Corporation agree to review, on a semi-annual basis, the actual division of Employee's time between Corporation and Tissue Bank.

3. Term of Agreement. This Agreement shall be effective as of February 13, 1998, and it shall continue in full force and effect for a period of five (5) years unless sooner terminated as hereinafter provided.

4. Compensation.

(a) Annual Salary. The Corporation shall pay to Employee as compensation for her services a salary of Seventy-Five Thousand Dollars ($75,000.00) per year, payable in equal monthly installments. Employee's salary shall be reviewed annually by the Corporation's Board of Directors, at which time Employee's salary may be adjusted as agreed upon by the Corporation's Board of Directors.

(b) Performance Bonus. To provide greater incentive for Employee by rewarding her with additional compensation, a cash bonus may be paid to Employee at any time during the year, or after the close of the year, based upon the performance of the Corporation and the performance of Employee during such year; provided, however, that the payment of any such bonus and the amount thereof shall be within the sole discretion of the Corporation's Board of Directors. In making such determination, the Directors will consider the following:

(i) The net profits of the Corporation for the year;

(ii) The base salary of Employee;

-2-

(iii) Employee's overall performance as an employee of the Corporation;

(iv) A comparison of Employee's performance with the performance of the other employees of the Corporation; and

(v) Such other matters as may be considered appropriate by the Directors.

(c) Stock of the Corporation. The Corporation shall issue to Employee Two Hundred Twenty Thousand (220,000) shares of common stock of the Corporation (the "Shares"). The Shares shall be issued as described herein only upon Employee's execution of a Stock Restriction Agreement for Regeneration Technologies, Inc. (the "Stock Restriction Agreement"), which, inter alia, restricts the transfer of the Shares and contains certain buy-back provisions regarding the Shares upon the termination of Employee's employment with the Corporation.

(d) Withholding, FICA, FUTA. Employee's salary and performance bonus, if any, shall be subject to, and reduced by, applicable federal income tax withholding and FICA tax, and any other taxes imposed by law.

5. Fringe Benefits. During the term of this Agreement, Employee shall be entitled to all fringe benefits offered generally to the Corporation's managerial employees as established or modified from time to time by the Corporation, pro rated based on the percentage of time Employee devotes to the Corporation, subject always to the rules in effect regarding participation in such plans. In addition, the Corporation shall obtain and maintain in force during the term of this Agreement a life insurance policy covering Employee's life in a

-3-

face value of not less than one million dollars ($1,000,000.00). The death benefit of such policy shall be made payable to the beneficiary or beneficiaries Employee may from time to time designate in writing.

6. Business Expenses. Except as otherwise provided herein, the Corporation shall pay, either directly or by reimbursement to Employee, such reasonable and necessary business expenses incurred by Employee in the course of her employment by the Corporation as are consistent with the Corporation's policies in existence from time to time, subject to such dollar limitations and verification and record keeping requirements as may be established from time to time by the Corporation.

7. Vacation. Employee shall be entitled to two (2) weeks paid vacation time each year. All vacations shall be taken by Employee at such time or times as may be approved by the Corporation. There will be no carryover of unused vacation time or sick leave from one year to another, and no compensation for such unused vacation or sick leave, if any.

8. Time Off. Employee shall be entitled to such time off with pay for attendance at seminars, courses, meetings and conventions as is authorized by the Corporation from time to time. The specific seminars, courses, meetings and conventions to be attended by Employee shall be subject to the Corporation's prior approval.

9. Termination of Employment.

(a) Voluntary Termination. Employee or the Corporation may voluntarily terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) at any time, by delivering to the other party

-4-

written notice of such intention not less than thirty (30) days prior to the effective date of termination. Notwithstanding the foregoing, if notice of termination is given by Employee to the Corporation, then the Corporation shall have the option of advancing the effective date of such termination to any date after receipt of such notice from Employee, which option shall be exercised by the Corporation within three (3) business days of receipt of such notice.

(b) Termination for Cause. The Corporation may immediately terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) for "cause" by giving written notice (without regard to the thirty (30) day period provided above) of such termination to Employee specifying the grounds therefor. A termination for "cause" shall only be for any one or more of the following reasons:

(i) Willfully or negligently damaging the Corporation's property, business, reputation or goodwill.

(ii) Willfully injuring any employee of the Corporation.

(iii) Willfully injuring any person in the course of the performance of services for the Corporation.

(iv) Lawfully charged with commission of a felony.

(v) Stealing, dishonesty, fraud or embezzlement.

(vi) Deliberate and continuous neglect of duty.

(vii) Use of alcohol or narcotics to the extent it prevents, in the sole judgment of the Corporation's Board of Directors, Employee from effectively performing the duties set forth in Paragraph 1 above.

-5-

(viii) Violating the covenants set forth in Paragraphs 10 or 11 of this Agreement.

The decision to terminate Employee's employment for "cause" shall be made by the Corporation's Board of Directors in its sole discretion.

(c) Termination Upon Death, Incompetency or Disability. Notwithstanding Subparagraph 9(a) above, the Corporation shall have the right to terminate Employee's employment with the Corporation (and, except as otherwise specifically provided hereunder, this Agreement) immediately and without prior written notice to Employee in the event that Employee dies, or is adjudicated incompetent, or is "permanently disabled", as hereinafter defined. As used herein, the term "permanently disabled" shall mean that Employee is unable to adequately perform her regular duties hereunder as a result of sickness or accident and such condition appears to be permanent. The determination of "permanent disability" shall be made by the Corporation's Board of Directors in its sole and absolute discretion and its decision shall be final and binding on Employee unless found to be arbitrary or capricious by a court of competent jurisdiction.

(d) Performance of Duties During Notice Period. In the event that Employee terminates Employee's employment with the Corporation in accordance with the terms of Subparagraph 9(a), Employee, if requested by the Corporation, shall continue to render services hereunder on behalf of the Corporation for the thirty (30) day period until the effective date of termination, and shall, in such event, be paid the compensation due Employee hereunder for the remainder of such period.

-6-

10. Confidential Information. Employee acknowledges and recognizes that, in connection with the performance of Employee's duties and obligations for the Corporation, Employee has and will have access to certain confidential information of the Corporation, including, but not limited to, any intellectual property of the Corporation, the identity of the Corporation's clients, the identity of prospective clients, the existence of negotiations with prospective clients of the Corporation, all drawings, records, sketches, models, financial information, customer information, trade secrets, and trade secrets relating to services of the Corporation, and products being developed by the Corporation (the "Confidential Information"). Employee hereby acknowledges that the maintenance of the confidentiality of the Confidential Information and restrictions on the use of the Confidential Information is essential to the Corporation. Employee shall not, at any time, whether during the term of this Agreement or after the termination of Employee's employment with the Corporation for any reason whatsoever, divulge or reveal any of the Confidential Information to any person, party or entity, directly or indirectly. In addition, Employee shall not utilize any of the Confidential Information for Employee's own benefit, or for the benefit of any subsequent employer or competitor of the Corporation. Employee shall maintain the Confidential Information in strict confidence and shall not copy, duplicate or otherwise reproduce, in whole or in part, such Confidential Information, except as necessary for Employee to perform services for the Corporation. Upon the termination of Employee's employment by the Corporation, or at the earlier request of the Corporation, Employee shall immediately surrender to the Corporation any and all memoranda, records, files or other documents and any other materials (including photocopies or other reproductions) containing or relating to the Confidential Information.

-7-

Employee shall indemnify and hold the Corporation harmless from any loss, damage, expense, cost or liability arising out of any unauthorized use or disclosure of the Confidential Information by Employee. The provisions of this Paragraph 10 shall survive the termination of Employee's employment with the Corporation and the termination of this Agreement.

11. Employee Developments. Employee is aware and understands that, during the term of Employee's employment with the Corporation or with the financial and other assistance that may be provided by the Corporation, Employee may invent, create, develop and improve certain valuable property such as, but not limited to, patents, trademarks, inventions, other patentable inventions and other trade secrets and formula, where such valuable property is (1) created during Employee's normal work hours; (2) created using the equipment or facilities of the Corporation; (3) created by Employee under the supervision or guidance of the Corporation; or (4) within the field of use which includes human or animal allograft tissue ("Employee Developments"). Employee agrees that all Employee Developments that may be developed or produced by Employee during Employee's employment by the Corporation are and will be the property of the Corporation and that Employee further agrees that she will, at the request of the Corporation, execute such documents as the Corporation may reasonably request from time to time, to assign and transfer all of the right, title and interest in Employee Developments to the Corporation and she will cooperate with the Corporation in connection with any patent applications. In this regard, Employee will, at all times, fully advise and inform the Corporation of all matters that Employee may be developing or working on while employed by the Corporation. Employee

-8-

further agrees that upon the termination of her employment with the Corporation for any reason whatsoever, Employee shall immediately deliver and surrender to the Corporation any and all plans, documents and other materials of any nature relating to the Employee Developments. The Corporation may provide additional compensation to Employee as consideration for Employee Developments in accordance with any patent policy of the Corporation. The provisions of this Paragraph 11 shall survive the termination of this Agreement.

12. Limitation of Employment.

(a) In the event of the termination of Employee's employment with the Corporation by the Corporation for cause (as defined in Subparagraph 9(b) above), Employee agrees that for a period of one (1) year following the effective date of such termination, Employee will not engage any business which receives, processes, or distributes human tissue within the United States. In the event of the termination of Employee's employment with the Corporation by the Corporation without cause, Employee agrees that for a period of one (1) year following the effective date of such termination, Employee will not engage in any business which receives, processes, or distributes human tissue within the United States; provided, however, that Employee shall then be entitled to a severance payment in the amount of one (1) times Employee's annual salary (computed without reference to shares of stock in the Corporation, fringe benefits, or any other form of compensation). The Corporation may require Employee to execute a release of claims against the Corporation as a condition precedent to its obligation to make the severance payment described herein.

-9-

(b) Employee acknowledges that this restrictive covenant is reasonably necessary to protect the Corporation's legitimate business interests, which are represented by, among other things, the substantial relationships between the Corporation and its licensees and tissue sources, as well as the goodwill established by the Corporation with licensees and tissue sources in the United States and other countries where the Corporation's tissues are distributed over a protracted period.

(c) Employee recognizes the fact that the Corporation would not sign this Agreement without the inclusion of this covenant, and Employee confirms the sufficiency of the consideration received by Employee, in the form of employment by the Corporation, in accepting this covenant as a material term of the Agreement.

(d) The parties acknowledge and agree that no amount of money would adequately compensate the Corporation for damages which the parties acknowledge would be suffered as a result of the violation of the terms of this provision by Employee, and they confirm that any such violation would result in irreparable injury to the Corporation because of the reduction in its income caused by the loss of or damage to the aforesaid relationships. It is agreed that the Corporation will be entitled to specific performance of this provision, and to injunctive relief, in view of the fact that the actual harm is not readily ascertainable or compensable by money damages.

(e) The period set forth in subparagraph (a) above will be tolled during any time in which Employee is in violation of the restrictive covenant contained in this Paragraph 12, and that period will begin to run again from the date Employee ceases such violation.

-10-

(f) This Paragraph 12 will survive the termination of this Agreement and the termination of Employee's employment with the Corporation.

13. Remedies For Breach. It is understood and agreed by the parties that no amount of money would adequately compensate the Corporation for damages which the parties acknowledge would be suffered as a result of a violation by the Employee of the covenants contained in Paragraphs 10, 11 and 12 above, and that, therefore, the Corporation shall be entitled, upon application to a court of competent jurisdiction, to obtain injunctive relief to enforce the provisions of Paragraphs 10, 11 and 12, which injunctive relief shall be in addition to any other rights or remedies available to the Corporation. If such a violation occurs, Employee shall be responsible for the payment of reasonable attorney's fees and other costs and expenses incurred by the Corporation in enforcing the covenants contained in Paragraphs 10, 11 and 12 above, whether incurred at the trial level or in any appellate proceeding. The provisions of this Paragraph 13 shall survive the termination of this Agreement.

14. Limitations on Authority. Without the express written consent of the Corporation's Board of Directors, Employee shall have no authority to do any of the following:

(a) Pledge the credit of the Corporation or any of its other employees;

(b) Bind the Corporation under any contract, agreement, note, mortgage or other obligation, except as provided in the Corporation's Standard Operating Procedures;

(c) Release or discharge any debt due the Corporation unless the Corporation has received the full amount thereof; or

-11-

(d) Sell, mortgage, transfer or otherwise dispose of any assets of the Corporation.

Notwithstanding the foregoing, Employee may bind the Corporation under contracts, agreements, notes, mortgages or other obligations up to a value of $100,000, provided the approval and signature of either the Corporation's President or Chief Financial Officer is also obtained with respect to same.

15. Severability. If any provision of this Agreement shall be declared invalid or unenforceable by a court of competent jurisdiction, the invalidity or unenforceability of such provision shall not affect the other provisions hereof, and this Agreement shall be construed and enforced in all respects as if such invalid or unenforceable provision was omitted.

16. Attorney's Fees and Costs. Except as provided in Paragraph 13 above, in the event a dispute arises between the parties hereto and suit is instituted, the prevailing party in such litigation shall be entitled to recover reasonable attorney's fees and other costs and expenses from the nonprevailing party, whether incurred at the trial level or in any appellate proceeding.

17. Governing Law; Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of Florida, and venue for any legal proceeding or action at law arising out of or construing this Agreement shall lie in the state courts of Alachua County, Florida, or the United States District Court for the Northern District of Florida, Gainesville Division.

The Administrator shall have full power and authority to take all other actions necessary to carry out the purpose and intent of the Plan, including, but not limited to, the authority to: (i) determine the eligible persons to whom, and the time or times at which Awards shall be granted; (ii) determine the types of Awards to be granted; (iii) determine the number of shares to be covered by or used for reference purposes for each Award; (iv) impose such terms, limitations, restrictions and conditions upon any such Award as the Administrator shall deem appropriate; (v) modify, amend, extend or renew outstanding Awards, or accept the surrender of outstanding Awards and substitute new Awards (provided however, that, except as provided in Section 7(d) of the Plan, any modification that would materially adversely affect any outstanding Award shall not be made without the consent of the holder); (vi) accelerate or otherwise change the time in which an Award may be exercised or becomes payable and to waive or accelerate the lapse, in whole or in part, of any restriction or condition with

-2-

respect to such Award, including, but not limited to, any restriction or condition with respect to the vesting or exercisability of an Award following termination of any grantee's employment; and (vii) establish objectives and conditions, if any, for earning Awards and determining whether Awards will be paid after the end of a performance period.

The Administrator shall have full power and authority, in its sole and absolute discretion, to administer and interpret the Plan and to adopt and interpret such rules, regulations, agreements, guidelines and instruments for the administration of the Plan and for the conduct of its business as the Administrator deems necessary or advisable.

(c) Non-Uniform Determinations. The Administrator's determinations under the Plan (including without limitation, determinations of the persons to receive Awards, the form, amount and timing of such Awards, the terms and provisions of such Awards and the Grant Agreements evidencing such Awards) need not be uniform and may be made by the Administrator selectively among persons who receive, or are eligible to receive, Awards under the Plan, whether or not such persons are similarly situated.

(d) Limited Liability. To the maximum extent permitted by law, no member of the Administrator shall be liable for any action taken or decision made in good faith relating to the Plan or any Award thereunder.

(e) Indemnification. To the maximum extent permitted by law and by the Corporation's charter and by-laws, the members of the Administrator shall be indemnified by the Corporation in respect of all their activities under the Plan.

(f) Effect of Administrator's Decision. All actions taken and decisions and determinations made by the Administrator on all matters relating to the Plan pursuant to the powers vested in it hereunder shall be in the Administrator's sole and absolute discretion and shall be conclusive and binding on all parties concerned, including the Corporation, its stockholders, any participants in the Plan and any other employee of the Corporation, and their respective successors in interest.

4. Shares Available for the Plan; Maximum Awards

Subject to adjustments as provided in Section 7(d) of the Plan, the shares of Common Stock that may be issued with respect to Awards granted under the Plan shall not exceed an aggregate of two hundred thousand (200,000) shares of Common Stock. The Corporation shall reserve such number of shares for Awards under the Plan, subject to adjustments as provided in Section 7(d) of the Plan. If any Award, or portion of an Award, under the Plan expires or terminates unexercised, becomes unexercisable or is forfeited or otherwise terminated, surrendered or canceled as to any shares, or if any shares of Common Stock are surrendered to the Corporation in connection with any Award (whether or not such surrendered shares were acquired pursuant to any Award), the shares subject to such Award and the surrendered shares shall thereafter be available for further Awards under the Plan; provided, however, that any such shares that are surrendered to the Corporation in connection with any Award or that are otherwise forfeited after issuance shall not be available for purchase pursuant to incentive stock options intended to qualify under Code section 422.

-3-

5. Participation

Participation in the Plan shall be open to all employees, officers, and directors of the Corporation, or of any Affiliate of the Corporation and to third parties which provide services to the Corporation, their employees and officers, as may be selected by the Administrator from time to time.

6. Awards

The Administrator, in its sole discretion, establishes the terms of all Awards granted under the Plan. Awards may be granted individually or in tandem with other types of Awards. All Awards are subject to the terms and conditions provided in the Grant Agreement.

(a) Stock Options. The Administrator may from time to time grant to eligible participants Awards of incentive stock options as that term is defined in Code section 422 or nonqualified stock options; provided, however, that Awards of incentive stock options shall be limited to employees of the Corporation or of any Parent or Subsidiary of the Corporation. Options intended to qualify as incentive stock options under Code section 422 must have an exercise price at least equal to Fair Market Value on the date of grant, but nonqualified stock options may be granted with an exercise price less than Fair Market Value. No stock option shall be an incentive stock option unless so designated by the Administrator at the time of grant or in the Grant Agreement evidencing such stock option.

(b) Stock Appreciation Rights. The Administrator may from time to time grant to eligible participants Awards of Stock Appreciation Rights ("SAR"). An SAR entitles the grantee to receive, subject to the provisions of the Plan and the Grant Agreement, a payment having an aggregate value equal to the product of
(i) the excess of (A) the Fair Market Value on the exercise date of one share of Common Stock over (B) the base price per share specified in the Grant Agreement, times (ii) the number of shares specified by the SAR, or portion thereof, which is exercised. Payment by the Corporation of the amount receivable upon any exercise of an SAR may be made by the delivery of Common Stock or cash, or any combination of Common Stock and cash, as determined in the sole discretion of the Administrator. If upon settlement of the exercise of an SAR a grantee is to receive a portion of such payment in shares of Common Stock, the number of shares shall be determined by dividing such portion by the Fair Market Value of a share of Common Stock on the exercise date. No fractional shares shall be used for such payment and the Administrator shall determine whether cash shall be given in lieu of such fractional shares or whether such fractional shares shall be eliminated.

(c) Stock Awards. The Administrator may from time to time grant restricted or unrestricted stock Awards to eligible participants in such amounts, on such terms and conditions, and for such consideration, including no consideration or such minimum consideration as may be required by law, as it shall determine. A stock Award may be paid in Common Stock, in cash, or in a combination of Common Stock and cash, as determined in the sole discretion of the Administrator.

(d) Phantom Stock. The Administrator may from time to time grant Awards to eligible participants denominated in stock-equivalent units ("phantom stock") in such amounts and on such terms and conditions as it shall determine. Phantom stock units granted to a participant shall be credited to a bookkeeping reserve account solely for accounting purposes and shall not require a segregation of any of the Corporation's assets. An Award of phantom stock may be settled in Common Stock, in cash, or in a combination of Common Stock and cash, as determined in the sole

-4-

discretion of the Administrator. Except as otherwise provided in the applicable Grant Agreement, the grantee shall not have the rights of a stockholder with respect to any shares of Common Stock represented by a phantom stock unit solely as a result of the grant of a phantom stock unit to the grantee.

(e) Performance Awards. The Administrator may, in its discretion, grant performance awards which become payable on account of attainment of one or more performance goals established by the Administrator. Performance awards may be paid by the delivery of Common Stock or cash, or any combination of Common Stock and cash, as determined in the sole discretion of the Administrator. Performance goals established by the Administrator may be based on the Corporation's or an Affiliate's operating income or one or more other business criteria selected by the Administrator that apply to an individual or group of individuals, a business unit, or the Corporation or an Affiliate as a whole, over such performance period as the Administrator may designate.

7. Miscellaneous

(a) Withholding of Taxes. Grantees and holders of Awards shall pay to the Corporation, or make provision satisfactory to the Administrator for payment of, any taxes required to be withheld in respect of Awards under the Plan no later than the date of the event creating the tax liability. The Corporation may, to the extent permitted by law, deduct any such tax obligations from any payment of any kind otherwise due to the grantee or holder of an Award. In the event that payment to the Corporation of such tax obligations is made in shares of Common Stock, such shares shall be valued at Fair Market Value on the applicable date for such purposes.

(b) Loans. The Corporation may make or guarantee loans to grantees to assist grantees in exercising Awards and satisfying any withholding tax obligations.

(c) Transferability. Except as otherwise determined by the Administrator, and in any event in the case of an incentive stock option or a stock appreciation right granted with respect to an incentive stock option, no Award granted under the Plan shall be transferable by a grantee otherwise than by will or the laws of descent and distribution. Unless otherwise determined by the Administrator in accord with the provisions of the immediately preceding sentence, an Award may be exercised during the lifetime of the grantee, only by the grantee or, during the period the grantee is under a legal disability, by the grantee's guardian or legal representative.

(d) Adjustments; Business Combinations. In the event of changes in the Common Stock of the Corporation by reason of any stock dividend, split-up, recapitalization, merger, consolidation. business combination or exchange of shares and the like, the Administrator shall, in its discretion, make appropriate adjustments to the maximum number and kind of shares reserved for issuance or with respect to which Awards may be granted under the Plan as provided in Section 4 of the Plan and to the number, kind and price of shares covered by Awards granted, and shall, in its discretion and without the consent of holders of Awards, make any other adjustments in Awards, including but not limited to reducing the number of shares subject to Awards or providing or mandating alternative settlement methods such as settlement of the Awards in cash or in shares of Common Stock or other securities of the Corporation or of any other entity, or in any other matters which relate to Awards as the Administrator shall, in its sole discretion, determine to be necessary or appropriate.

-5-

Notwithstanding anything in the Plan to the contrary and without the consent of holders of Awards, the Administrator, in its sole discretion, may make any modifications to any Awards, including but not limited to cancellation, forfeiture, surrender or other termination of the Awards in whole or in part regardless of the vested status of the Award, in order to facilitate any business combination that is authorized by the Board to comply with requirements for treatment as a pooling of interests transaction for accounting purposes under generally accepted accounting principles.

The Administrator is authorized to make, in its discretion and without the consent of holders of Awards, adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events affecting the Corporation, or the financial statements of the Corporation or any Subsidiary, or of changes in applicable laws, regulations, or accounting principles, whenever the Administrator determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

(e) Stockholders' Agreement. As a condition precedent to the grant of any Award under the Plan or the exercise pursuant to such an Award or to the delivery of certificates for shares issued pursuant to any Award, the Administrator may require the grantee or the grantee's successor or permitted transferee, as the case may be, to become a party to the Stockholders' Agreement of the Corporation and/or to a stock restriction agreement substantially in the form attached hereto as Attachment A.

(f) Termination, Amendment and Modification of the Plan. The Board may terminate, amend or modify the Plan or any portion thereof at any time.

(g) Non-Guarantee of Employment or Service. Nothing in the Plan or in any Grant Agreement thereunder shall confer any right on an individual to continue in the service of the Corporation or shall interfere in any way with the right of the Corporation to terminate such service at any time.

(h) Compliance with Securities Laws; Listing and Registration. Common Stock shall not be issued with respect to an Award granted under the Plan unless the exercise of such Award and the issuance and delivery of stock certificates for such Common Stock pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act of 1933 and the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any national securities exchange or any listing or quotation system established by the National Association of Securities Dealers, Inc. ("Nasdaq System") upon which the Common Stock may then be listed or quoted, and shall be further subject to the approval of counsel for the Corporation with respect to such compliance to the extent such approval is sought by the Administrator. The Corporation may require that a grantee, as a condition to exercise of an Award, and as a condition to the delivery of any share certificate, provide to the Corporation, at the time of each such exercise and each such delivery, a written representation that the shares of Common Stock being acquired shall be acquired by the grantee solely for investment and will not be sold or transferred without registration or the availability of an exemption from registration under the Securities Act and applicable state securities laws. The Corporation may also require that a grantee submit other written representations which will permit the Corporation to comply with federal and applicable state securities laws in connection with the issuance of the Common Stock, including representations as to the knowledge and experience in financial and business matters of the grantee and the grantee's ability to bear the economic risk of the grantee's

-6-

investment. The Corporation may require that the grantee obtain a "purchaser representative" as that term is defined in applicable federal and state securities laws. The stock certificates for any shares of Common Stock issued pursuant to this Plan may bear a legend restricting transferability of the shares of Common Stock unless such shares are registered or an exemption from registration is available under the Securities Act and applicable state securities laws. The Corporation may notify its transfer agent to stop any transfer of shares of Common Stock not made in compliance with these restrictions. If the Corporation determines that the listing, registration or qualification upon any securities exchange or upon the Nasdaq System or under any law, of shares subject to any Award is necessary or desirable as a condition of, or in connection with, the granting of the Award or the issuance or purchase of shares thereunder, no such Award may be exercised in whole or in part and no restrictions on such Award shall lapse, unless such listing, registration or qualification is effected free of any conditions not acceptable to the Corporation.

(i) No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Corporation and a grantee or any other person. To the extent that any grantee or other person acquires a right to receive payments from the Corporation pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Corporation.

(j) Governing Law. The validity, construction and effect of the Plan, of Grant Agreements entered into pursuant to the Plan, and of any rules, regulations, determinations or decisions made by the Administrator relating to the Plan or such Grant Agreements, and the rights of any and all persons having or claiming to have any interest therein or thereunder, shall be determined exclusively in accordance with applicable federal laws and the laws of Florida without regard to its conflict of laws principles.

(k) Effective Date; Termination Date. The Plan is effective as of the date on which the Plan was adopted by the Board, subject to approval of the stockholders within twelve months before or after such date. No Award shall be granted under the Plan after the close of business on the day immediately preceding the tenth anniversary of the effective date of the Plan. Subject to other applicable provisions of the Plan, all Awards made under the Plan prior to such termination of the Plan shall remain in effect until such Awards have been satisfied or terminated in accordance with the Plan and the terms of such Awards.

   Non-Exempt                                    VI

Calculating the Incentive Pool under the RTI Corporate Plan:

The pool of funds that is available for incentives under the RTI Corporate Plan is computed as a percentage of the company's performance over budgetary targets. For 2000, that overall corporate target is:

o Overall corporate Pre-Tax Operating Income above the Budget level

Each department within the company has other targets which must be achieved in order to achieve full participation in the pool of funds that is available. These departmental targets include such items as corporate revenue above baselines, product-line revenue above baselines, new product introductions, etc.

How Individual awards are computed in the RTI Corporate Plan:

Incentive award opportunities in the RTI Corporate Plan are computed based on the following factors:

o Overall Corporate Performance (above)
o Achievement of Departmental Goals & Metrics
o Individual Performance

Participants in the RTI Corporate Plan do not achieve any awards unless profits are above to the company's "Budget" level for profits.

Computing the Pool Available for the RTI Corporate Plan:

The pool of funds potentially available for pay-out under the RTI Corporate Plan is computed as follows:

If Plan Income* is at or below RTI's "Budget" for Plan Income:


-0-Funding of Pool

If Plan Income is above "Budget" for Plan Income:
+ 30.0% of Plan Income above "Budgeted" Plan Income

"Budgeted Net Income" for Year 2000 does not include any incentive compensation expense, as no incentive compensation is earned until earnings exceed Budgeted Net Income.

Examples of Pool Available at "Budget" & "Internal Target":

                                                 At        At      At 110%

Division of the Pool Among Participant Groups:

Assuming an incentive pool is earned as described above, the pool will be divided initially among the six categories of employees as reflected below, creating six sub-pools. The percentage for each sub-pool has been calculated to result in a potential pay-out, if the company achieves it's Internal Profit Target (above "Budget"), of the following multiple of "base compensation":

                                      % of Base Pay          % of Pool
Job Levels            Group         at Internal Target        Required
    CEO/CFO/COO          I         35% of base earnings     14.2% of Pool
    Vice Presidents      II        30% of base earnings      8.3% of Pool
    Directors            III       25% of base earnings     20.4% of Pool
    Managers             IV        15% of base earnings     18.8% of Pool
    Exempt               V         10% of base earnings     17.6% of Pool
    Non-Exempt           VI             5% of earned(1)     20.7% of Pool

1. Expressed as a percentage of earnings, including overtime payments, for non-exempt participants, in order to prevent overtime from being used to increase the "base wages" qualifying for incentives.

All individual pay-outs from the sub-pools will be dependent upon achievement of Department goals and individual performance, and subject to executive review.

No pay-out exists if the company only achieves the "Budget" level of Net Income. At 110% of "Internal Target" Net Profit, the pay-outs are estimated to be roughly 60% higher for each bracket than the percentages shown above. Page 9, "Revenue, Profit & Plan Income for 2000 Budget Year," reflects the pay-outs projected, by category, at Budget, Internal Target, and 110% of Internal Target.

Regeneration Technologies, Inc. - Incentive Compensation Plan - -Year 2000-

RTI Corporate Plan, cont.:

Recap:

1. The "Incentive Pool" will only exist if the company achieves its Budgeted Net Profit level
2. After Budgeted Net Profit level is achieved, the Pool is increased only as a percentage of earnings above the Budget
3. Employees will still be required to achieve Departmental goals to participate in the potential Pool
4. Individual performance will be used to determine the final pay-out (if any) from the pool
5. A review of all proposed pay-outs under the Plan will be conducted by the company's CEO, COO and CEO prior to any pay-outs

Specific goals of each Department (or Business Unit) will be weighted based on importance
