                        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
<PAGE>
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
<PAGE>
    - 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
<PAGE>
    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
<PAGE>
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
<PAGE>
    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
<PAGE>
    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
<PAGE>
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
<PAGE>
    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
<PAGE>
    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.

<PAGE>
                                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.

    The following table sets forth our capitalization as of December 31, 1999:

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

commissions and other estimated offering expenses and the application of the
estimated net proceeds. This table should be read along with "Management's

                                    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. To the extent any of these options or warrants are
exercised, there will be further dilution to new investors. The following table
illustrates this per share dilution:

    If the underwriters' over-allotment option is exercised in full, our pro
forma as adjusted net tangible book value at December 31, 1999 would have been

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.

               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
<PAGE>
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.

                                       19
<PAGE>
    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
<PAGE>
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.

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
<PAGE>
    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
<PAGE>
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:

    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
<PAGE>
    - 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
<PAGE>
    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:

</TABLE>

    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
<PAGE>
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

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.

PRODUCTS AND PRODUCTS IN DEVELOPMENT

    OVERVIEW

    We process human musculoskeletal and other tissue, including bone,
cartilage, tendon, ligament, pericardial and cardiovascular tissue, in producing
our line of proprietary allografts. Our current tissues range from
conventionally processed bone and soft tissue to precision tooled bone implants,
soft tissue, urological allografts and heart valves. The service fees we charge
for our allografts vary extensively, ranging from a list fee of less than $200
to in excess of $7,000. Our most commonly used precision-tooled spinal
allografts have listed services fees ranging from approximately $1,000 to
$2,000. The following table summarizes our current allograft offerings in each
of the markets we serve, current distribution of these allografts and the

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.

<PAGE>
    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.

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
<PAGE>
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.

    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
<PAGE>
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
<PAGE>
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
<PAGE>
    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
<PAGE>
    - 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
<PAGE>
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
<PAGE>
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
<PAGE>
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

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.

the board of directors. Our directors who are not also our employees are
eligible to receive a stipend of $1,000 per meeting, as well as reimbursement
for their expenses incurred relating to their attendance at meetings of the
board of directors. Under our Omnibus Stock Option Plan, at the discretion of
our board of directors or compensation committee, our directors also are
eligible to receive awards of non-qualified stock options. Our directors who are
not also employees receive an annual grant of an option to purchase       shares
of our common stock.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    No member of our compensation committee has been an employee of ours. None
of our executive officers serves as a member of the board of directors or
compensation committee of any other entity that has one or more executive
officers serving as a member of our board of directors or our compensation
committee.

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
<PAGE>
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
<PAGE>
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.

(1) Percentage ownership is based on             shares outstanding as of
    March 31, 2000. Shares of common stock subject to options currently
    exercisable or exercisable within 60 days of March 31, 2000 are deemed

                          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
$      .

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
<PAGE>
      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             .

<PAGE>
                        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:

</TABLE>

    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
<PAGE>
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

    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.

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:

    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:

<TABLE>

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
</TABLE>

    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.

    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:

</TABLE>

    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

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:

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. In addition, the Company must satisfy certain financial ratios
including a fixed charge ratio of 1.10 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 Company was in compliance with all covenants and
financial ratios at December 31, 1999.

    The total amount outstanding on the line of credit December 31, 1999 was
$2,787,475.

    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:

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

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

    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

    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

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.

    Rent expense for the periods ended December 31, 1998 and 1999 was $262,698
and $748,473, respectively.

    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

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.

                          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:

<TABLE>
<S>                                                           <C>
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
</TABLE>

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

assumptions that affected the reported amounts of revenues and direct expenses
during the reporting period. Actual results could differ from those estimates.

3. CONCENTRATIONS OF RISK

    The Company's principal concentration of risk was related to its limited
distribution channels. During 1997 and the period from January 1, 1998 to
February 11, 1998, approximately 90% of the Company's revenues came from one of
the distribution companies.

4. COMMITMENTS AND CONTINGENCIES

    CAPITAL LEASE OBLIGATIONS--Future minimum lease payments on capital lease
obligations as of December 31, 1997 were as follows:

                                                              $  903,910
                                                              ==========
</TABLE>

Future minimum lease payments on capital lease obligations as of February 11,
1998 approximated those represented by the schedule above.

    OPERATING LEASE OBLIGATIONS--The Company leased office equipment under
various operating leases expiring through 2001. On January 1, 1998, the Company
entered into an additional operating lease for office equipment.

    Future minimum operating lease payments required under noncancelable
operating lease agreements as of December 31, 1997 and February 11, 1998 were
not significant. Rent expense relating to operating leases for the year ended
December 31, 1997 and for the period from January 1, 1998 through February 11,
1998 were approximately $2,900 and $375, respectively.

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

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
<PAGE>
    - 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.

offerings), holders of Common Stock issued or issuable upon conversion of the
Class A 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 A 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

Shares as such Stockholders may request in such notice of election. The Company

registration on Form S-3, or such successor form, of all Class A Registrable
Shares which the Company has been requested to register.

has fixed plans to engage within thirty (30) days of the time of the request in
a registered public offering as to which the Stockholders may include Class A
Registrable Shares pursuant to subsection 1.4 or is engaged in any other
activity which, in the good faith determination of the Company's Board of
Directors, would be adversely affected by the requested registration to the
material detriment of the Company, then the Company may at its option direct
that such request be delayed for a period not in excess of 180 days from the
effective date of such offering or the date of commencement of such other
material activity, as the case may be, such right to delay a request to be
exercised by the Company not more than once in any two year period.

the Class B Stockholders were provided an opportunity to effect the sale of
Class B Registrable Shares pursuant to such Registration Statement; and provided
further that the Company shall not be required to effect more than two

                  (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

                                     - 8 -
<PAGE>

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

                  (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 -
<PAGE>

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 -
<PAGE>

      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 -
<PAGE>

            (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 -
<PAGE>

            (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 -
<PAGE>

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 -
<PAGE>

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 -
<PAGE>

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 -
<PAGE>

                  (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 -
<PAGE>

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.

            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.

            2.3 Subsequent Transferees. A transferee to whom rights are
transferred pursuant to this Section 2 may not again transfer such rights to any
other person or entity, other than as provided in Subsection 2.1 or Subsection
2.2 above

                                   ARTICLE III
                                  MISCELLANEOUS

            3.1 No Inconsistent Agreements. The Company will not hereafter enter
into any agreement with respect to its securities which is inconsistent with or
violates the rights granted to the holders of Registrable Shares in this
Agreement.

            3.2 Adjustments Affecting Registrable Shares. The Company will not
take any action, or permit any change to occur, with respect to its securities
that would adversely affect the ability of the holders of Registrable Shares to
include such Registrable Shares in a registration undertaken pursuant to this
Agreement or that would adversely affect the marketability of such Registrable
Shares in any such registration (including, without limitation, effecting a
stock split or a combination of shares).

            3.3 Remedies. Any person having rights under any provision of this
Agreement will be entitled to enforce such rights specifically (without posting
any bond or other security), to recover damages caused by reason of any breach
of any provision of this Agreement and to exercise all other rights granted by
law.

            3.4 Amendments and Waivers. Except as otherwise provided herein, the
provisions of this Agreement may be amended and the Company may take action
herein prohibited, or omit to perform any act herein required to be performed by
it, if, but only if, the Company has obtained the written consent of holders of
at least 2/3 of each of the Class A, the Class B and the Class C Registrable
Shares then in existence.

            3.5 Successors and Assigns. All covenants and agreements in this
Agreement by or on behalf of any of the parties hereto will bind and inure to
the benefit of the respective successors and assigns of the parties hereto
whether so expressed or not. In addition, irrespective of whether any express
assignment has been made, the provisions of this Agreement that are for the
benefit of purchasers or holders of Registrable Shares are also for the benefit
of; and enforceable by, any subsequent holder permitted by Section 2.1.

            3.6 Governing Law. This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of Florida.
Each of the Company and each Investor hereby irrevocably and unconditionally
submit to the jurisdiction of the courts of the State of Florida and the United
States of America located in the State of Florida (the "Florida Courts") for
any litigation arising out of or relating to this Agreement and the transactions
contemplated hereby (and agree not to commence any litigation relating thereto
except in such courts), consent to service of process in such Florida Courts,
waive any objection to the laying of

venue of any such litigation in Alachua County, Florida, and agree not to plead
or claim in any Florida Court that such litigation brought therein has been
brought in any inconvenient forum.

contrary contained herein, the registration rights of each holder of Registrable
Shares set forth in Section 1 shall terminate in their entirety on the fifth
anniversary of a Qualified Class A, Qualified Class B or Qualified Class C

designated by such group as nominees for election as directors. If a group shall
fail to give notice to the Company as provided above, it shall be deemed that

2. Preemptive Rights.

      (a) The Company hereby grants to each of the Preferred Stockholders a
preemptive right to purchase, on a pro rata basis, all or any part of New
Securities (as defined below) that the


                                      -4-
<PAGE>

Company may, from time to time, propose to sell and issue, subject to the terms
and conditions set forth below. Each Preferred Stockholders' pro rata share, for
purposes of this subsection 2(a), equal a fraction, the numerator of which is
the aggregate number of shares of Common Stock then held by the Preferred
Stockholders or issuable upon conversion or exercise of any shares, convertible
securities, options, rights or warrants then held by the Preferred Stockholders,
and the denominator of which is the total number of shares of Common Stock then
held by the Preferred Stockholders plus the number of shares of Common Stock
issuable upon conversion or exercise of then outstanding Shares, convertible
securities, options, rights or warrants, then held by the Preferred
Stockholders.

            (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;
(iii) securities offered to the public pursuant to a Registration Statement;
(iv) securities issued for the acquisition of another corporation by the Company
by merger, purchase of substantially all the assets of such corporation or other
reorganization resulting in the ownership by the Company of not less than 51% of
the voting power of such corporation; (v) up to 400,000 shares of Common C)
Stock issued to employees or consultants of the Company or UFTB pursuant to a
Board-approved stock option plan, employee stock purchase plan, restricted stock
plan or other employee stock plan or option agreement; (vi) securities issued as
a result of any stock split, stock dividend or reclassification of Common Stock,
distributable on a pro rata basis to all holders of Common Stock; (vii) shares
of Common Stock issuable upon the exercise of any warrant issued by the Company
prior to or as of the date hereof, including Common Stock Warrants issued to
each of Stephens and Medtronic in connection that certain Convertible Class C

any shares of stock of the Company to be issued in connection with the
acquisition by the Company of Georgia Tissue Bank, Inc.

            (c) In the event the Company intends to issue New Securities, it
shall give the Preferred Stockholders written notice of such intention,
describing the type of New Securities to be issued, the price thereof and the
general terms upon which the Company proposes to effect such issuance. 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-
<PAGE>

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.

written instrument confirming that such transferee shall be bound by all of the

      (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

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

<PAGE>

conditions including deferred payment (if applicable), set forth therein,

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),

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.

<PAGE>

      (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. The Company's approval
shall be deemed to given if the Company has not objected to the transfer within
10 days of its receipt of notification of the identity of the Proposed
Transferee. If the Company has not objected to the sale within such 10-day
period, then the Selling Stockholder shall be free to consummate the sale to the
Proposed Transferee for a period of ninety days commencing on the otermination
of the Company's and the Preferred Stockholders' 40-day period to exercise their
night of First Refusal pursuant to Section 3(d) above.

      (g) Effect of Prohibited Transfer. The Company shall not be required (a)
to transfer on its books any of the Shares or Common Stock, as the case may be,
which shall have been sold or transferred in violation of any of the provisions
set forth in this Agreement, or (b) to neat as owner of such Shares or Common
Stock, as applicable, or to pay dividends to any transferee to whom any such
Shares or Common Stock, as applicable, shall have been so sold or transferred.

      (h) The restrictions of this Section 3 shall not apply to shares of Common
Stock sold in connection with a public offering of shares of the Company's
Common Stock pursuant to an effective registration statement under the
Securities Act (a "Public Offering") and shall terminate in their entirety on
the earliest of (i) the closing of the Company's initial Public Offering or (ii)
the agreement of the Company and all of the Preferred Stockholders.

      (a) No Specified Common Stockholder or Preferred Stockholder (the "Co-Sale

stock now or hereafter held by him, other than as provided in this Section 4,

inuring to the benefit of the Company and the other Preferred Stockholders, and
(b) thereafter, he notifies each Preferred Stockholder of the proposed
transaction and gives such Preferred Stockholders the opportunity to include in
the sale to the proposed transferee, shares of stock. The aggregate number of
shares of stock that a Preferred Stockholder shall be entitled to have included
in such sale will be that number that upon conversion into Common Stock at the
applicable conversion rate would bear the same proportion oto the total number
of shares of stock proposed to be sold by the Co-Sale Stockholder as the total
Dumber of shares of stock held by the Preferred Stockholder bears to the
aggregate number of `Shares of the Company's Common Stock (calculated on a fully
diluted basis), and each Preferred K


                                      -8-
<PAGE>

Stockholder shall be entitled to participate in such number pro rata on the
basis of the number of shares of stock then held by him or it. Each Preferred
Stockholder shall have a period of fifteen (15) days (the "Offer Period"), from
the date notice of such opportunity is received to give the Co-Sale Stockholder
written notice of his or its desire to participate in such sale, stating in such
notice the number of shares desired to be sold; and if no such notice is given
within the Offer Period, such Preferred Stockholder shall be deemed to have
chosen not to participate.

      (b) Notwithstanding the foregoing, the provisions of Section 4(a) shall be
inapplicable to the following transactions:

            (i) A transfer of any or all of a Preferred Stockholder's stock to
an affiliate;

sister of the Preferred Stockholder making such transfer;

partners, as the case may be;

            (iv) The sale, assignment or transfer by way of bequest or
inheritance upon death of a Preferred Stockholder;

            (v) The sale, assignment or transfer to the Company pursuant to the
right of first refusal provisions set forth in this Agreement, as they may from
time to time be amended; or

promise, agreement or understanding set forth herein shall not be construed as a
waiver or relinquishment of the right to insist upon strict performance of the

premiums paid by Landlord for the Building is caused by Tenant's use of the
Leased Premises, or if Tenant vacates the Leased Premises and causes an increase

including the obligation to pay Rent, except that Tenant shall pay Landlord as
an installment of the Annual Gross Rent for the period of such holdover an
amount equal to two times (200%) The Annual Gross Rent which would have been

this Lease. The rental payable during the holdover period shall be payable to
Landlord on demand.

Additional Rent to be paid by Tenant hereunder, Tenant shall be liable and pay
to Landlord all rental, sales and use taxes, if any, levied or imposed by any

concurrently with the payment of the Rent or other charge upon which the tax is
based as set forth above.

      provisions hereof shall apply to every transfer or assignment made of the

alterations as required under this Lease or as Landlord may reasonably deem
necessary or desirable, and Landlord shall be allowed to take all material into
and upon the Leased Premises that may be required therefore without the same

provided, however, if the necessity of such repairs do not arise due to the

voluntary governmental energy conservation or environmental protection program,
or any other happening beyond the control of Landlord. Except as expressly
provided hereinafter, Landlord will not be liable for damages to persons or
property or for injury to, or interruption of, business for any discontinuance

Landlord to the Building provided such changes do not detract from the level of
the existing services. Landlord shall not be liable for any damages to persons
or property or for injury to, or interruption of, business arising from the
interruption of any utility service to the Building. If there is a failure by
Landlord to furnish the services specified in this Section, and further provided
such interruption is not due to Tenant's negligence or willful misconduct, and
further provided, should the unavailability of such service render all or any
portion of the Leased Premises unusable by Tenant for Tenant's permitted use,
Tenant may, after and upon the giving of five (5) days written notice to
Landlord, deduct the rent for that portion of the Leased Premises which is so
unusable provided same is not due to Excusable Delays. Landlord reserves the
right from time to time to make changes in the services provided by Landlord to
the Building provided such changes do not detract from the level of the existing
services.

                     ARTICLE 7. ALTERATIONS AND IMPROVEMENTS

      7.1. Leasehold Improvements. If construction to the Leased Premises is to
be performed by Landlord prior to or during Tenant's occupancy, Landlord will
complete the construction of the improvements to the Leased Premises in
accordance with plans and specifications agreed to by Landlord and Tenant.

improvements to any portion of the Leased Premises or the Building which may
cause or create penetrations to the roof, ceiling or floors thereof. Within
seven days of receipt of plans and specifications, Tenant shall execute a copy
of the plans and specifications and, if applicable, change orders setting forth
the amount of any costs to be borne by Tenant. In the event Tenant fails to

terms of access for construction. Any Alterations to the Leased Premises made by
Tenant shall at once become the property of Landlord and shall be surrendered to
Landlord upon the termination of this Lease provided, however, Landlord, at its

accordance with the requirements of this Lease. Tenant, at its expense, shall
obtain all necessary governmental permits and certificates for the commencement
and prosecution of the Alterations and for final approval thereof upon

liability under the Construction Lien Law of the State of Florida, it being
expressly understood that the Landlord's estate shall not be subject to such
liability. Tenant shall strictly comply with the Construction Lien law of the
State of Florida, as set forth in Chapter 713, Florida Statutes. Notwithstanding
the foregoing, Tenant, at its expense, shall cause any lien filed against the

Parking Area for work, services or materials claimed to have been furnished to
or for the benefit of Tenant (other than on account of the Leasehold Work) to be
satisfied or transferred to bond within twenty (20) days after Tenant's having
received notice thereof. In the event that Tenant fails to satisfy or transfer
to bond such claim of lien within said twenty (20) day period the Landlord may
do so and thereafter charge the Tenant as additional rent, all costs incurred by
the Landlord in


                                       9

connection with the satisfaction or transfer of such claim, including attorneys'
fees plus interest thereon at the Default Rate. Further, the Tenant agrees to
indemnify, defend, and save the Landlord harmless from and against any damage or
loss incurred by the Landlord as a result of any such mechanic's Claim of Lien.
This Section shall survive the termination of this Lease.

construct pursuant hereto and to the extent only of proceeds received by
Landlord from its insurerers), except Tenant, at its sole cost and expense,

specified in this Lease shall be abated or equitably reduced proportionately
during any period in which, by reason of such damage or destruction, there is
substantial interference with the operation of the business of Tenant in the
Leased Premises, and such abatement or equitable reduction shall continue for
the period commencing with such destruction or damage and ending with the
completion by Landlord of such work of repair and/or restoration as Landlord is
obligated to do. In the event of the termination of this Lease pursuant to this
Section 8, this Lease, and the Term hereof, shall cease and come to an end as of
the date of such damage or destruction. Any Annual Gross Rent or other charges
paid in advance by Tenant shall be promptly refunded by Landlord.

      8.4. Landlord's Limitation of Obligation. Despite anything contained in
this Lease to the contrary, and without limiting Landlord's right or remedies

      (a) If damage or destruction occurs to the Leased Premises or any part
      thereof by reason of any cause in respect of which there are no proceeds
      of insurance available to Landlord, or

      (b) If the proceeds of insurance are insufficient to pay Landlord for the
      costs of rebuilding or making fit the Leased Premises), or

      (c) If any mortgagee or other person entitled to the proceeds of insurance
      does not consent to the payment to Landlord of such proceeds for such
      purpose, or

      (d) If in Landlord's reasonable opinion any such damage or destruction is
      caused by any fault, neglect, default negligence, act, or omission of
      Tenant or those for whom Tenant is in law responsible, or any other person
      entering upon the Leased Premises under express or implied invitation of
      Tenant,

then Landlord may, without obligation or liability to Tenant, terminate this
Lease on 30 days' written notice to Tenant and all Rent shall be adjusted as of,
and Tenant shall vacate and surrender the Leased Premises on, such termination
date.

been damaged or destroyed by fire or other casualty to the extent that the cost
of restoration of the Building will exceed a sum constituting sixty percent
(60%) of the total replacement cost thereof, Landlord shall have the right to
terminate this Lease provided that notice thereof is given to Tenant not later
than sixty (60) days after such damage or destruction and Landlord elects not to

eminent domain or conveyed in lieu thereof; or (ii) as a result of a taking by
eminent domain or the action of any public or quasi-public authority or a
conveyance in lieu thereof, the means of ingress or egress to and from the
Building is so permanently altered as to materially and adversely affect the
flow of traffic in, to, from or about the Building; then, in any of the
foregoing events, the Lease Term shall, at the option of Tenant, cease and
terminate as of the day possession shall be taken by the acting governmental or
quasi-governmental authority (the "Date of Taking"). Such option to terminate
shall be exercisable by Tenant giving written notice to Landlord on or before
thirty (30) days after the Date of Taking, which notice shall provide for a
termination date (the "Termination Date") not later than ninety (90) days after
the Date of Taking and Tenant shall pay Rent up to the Termination Date, and
Landlord shall refund such Annual Gross Rent and other payments as shall have
been paid in advance and which cover a period subsequent to the Termination
Date. In the event Tenant does not terminate this Lease, Landlord shall promptly
and diligently restore the Building and the Leased Premises and the Building and
Common Areas to as near to their condition prior to such taking or conveyance as
is reasonably possible, and, during the course of such restoration, there shall
be a fair and equitable abatement of all Annual Gross Rent, taking into account
the extent to which Tenant shall be required to close down all or a portion of
its operations until restoration has been completed; and, after such
restoration, there shall be fair and equitable abatement of Annual Gross Rent on
a permanent basis, taking into account the reduction in the size of the Leased
Premises, reduction in Common Areas, and the like. If fifty percent (50%) or
more of the rentable area in the Building is taken by eminent domain or conveyed
in lieu thereof, then Landlord shall have the right to terminate this Lease by
giving written notice to Tenant on or before thirty (30) days after the Date of
Taking; provided that Landlord also terminates all leases for premises within
the Building.

      11.2. Restoration. If any portion of the Leased Premises shall be so taken
or conveyed and this Lease is not terminated, then the Lease Term shall cease
only with respect to that portion of the Leased Premises so taken or conveyed,
as of the day possession shall be taken, and Tenant shall pay Annual Gross Rent
and all other payments up to that day, with an appropriate refund by Landlord of
such Rent as may have been paid in advance for a period subsequent to the date
of the taking of possession and, Thereafter, the Annual Gross Rent and all other
payments shall be equitably adjusted. Landlord shall, at its expense, make all
necessary repairs or alterations so as to constitute the remaining portion of
the Leased Premises a complete architectural unit. It is understood and agreed
that Tenant shall not have the right to claim damages for the value of its
leasehold estate, nor shall Tenant have the right to share in any award granted
to Tenant, nor shall Tenant have the right to claim damages that in any way may
be in derogation of Landlord's award.

                       ARTICLE 12. ASSIGNMENT OR SUBLEASE

      12.1. Landlord Assignment. Landlord shall have the right to sell, transfer
or assign, in whole or in part, its rights and obligations under this Lease and
in the Building. Any such sale transfer or assignment shall operate to release
Landlord from any and all liabilities under this Lease arising after the date of
such sale, assignment or transfer, provided such transferee or assignee assumes
such liabilities in writing. The acceptance of rent by any such transferee or
assignee shall constitute assumption of such liabilities.

      12.2. Tenant Assignment.

      (a) Tenant shall not assign, in whole or in part, this Lease, or allow it
      to be assigned, in whole or in part, by operation of law or otherwise or
      mortgage or pledge the same, or sublet the Leased Premises, in whole or in
      part, without the prior written consent of Landlord, which consent shall
      not be unreasonably withheld. In no event shall any such assignment or
      sublease ever release Tenant or any guarantor from any obligation or
      liability hereunder.

      (b) If Tenant desires to assign or sublet all or any part of the Leased
      Premises to any party, it shall so notify Landlord at least thirty days in
      advance of the date on which Tenant desires to make such assignment or
      sublease. 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.

            ARTICLE 13. SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT

      13.1. Rights of Mortgagee. Tenant acknowledges and agrees that this Lease
shall be subject and subordinate to the lien of all existing and future
mortgages on the Leased Premises and shall, within 15 days of Landlord's
request, execute such subordination agreements as my be submitted by the holders
of such mortgages. Tenant will, upon request of the lienholder, will agree that,
if such lienholder succeeds to the interest of Landlord, Tenant will recognize
said lienholder (or successor in interest of the lienholder) as its landlord
under the terms of this Lease. Tenant hereby constitutes and appoints Landlord
as Tenant's attorney-in-fact to execute any such instrument on behalf of Tenant.

                           ARTICLE 14. LANDLORD'S LIEN

      14.1. Uniform Commercial Code. This Lease is intended as and constitutes a
security agreement within the meaning of the Uniform Commercial Code of the
state in which the Leased Premises are situated. Landlord, in addition to the
rights prescribed in this Lease and by law, shall have all of the rights,
titles, liens and interests in and to Tenant's property (but expressly excluding
any of Tenant's interests in intellectual property and human tissue in any
form), now or hereafter located upon the Leased Premises, which may be granted a
secured party, as that term is defined, under the Uniform Commercial Code to
secure to Landlord payment of all sums due and the full performance of all
Tenant's covenants under this Lease. Tenant will on request execute and deliver
to Landlord a financing statement for the purpose of perfecting Landlords
security interest under this Lease or Landlord may file this Lease or a copy
thereof as a financing statement. Unless otherwise provided by law and for the
purpose of exercising any right pursuant to this section, Landlord and Tenant
agree that reasonable notice shall be met if such notice is given by ten days
written notice, certified mail, return receipt requested, to Landlord or Tenant
at the addresses specified herein.

                        ARTICLE 15. DEFAULT AND REMEDIES

      15.1. Default by Tenant. The following shall be deemed to be events of
default by Tenant under this Lease: (i) Tenant shall fail to pay any installment
of Annual Gross Rent or any other Additional Rent, or any other charge or
assessment against Tenant pursuant to the terms hereof and such failure to pay
shall continue for more than ten (10) days after the same is due; (ii) Tenant
shall fail to comply with any term, provision, covenant, agreement or warranty
made under this Lease by Tenant, other than the payment of any installment of
Annual Gross Rent or any other Additional Rent or other charge or assessment
payable by Tenant, and shall not cure such failure within thirty (30) days after
written notice thereof to Tenant; (iii) a petition in bankruptcy or insolvency
or for reorganization or for the appointment of a receiver or trustee of all or
substantially all of Tenant's assets is filed against Tenant in any court
pursuant to any statute either of the United States or of any state and Tenant
fails to secure or diligently proceed to secure a discharge thereof within sixty
(60) days, or if Tenant voluntarily files a petition in bankruptcy or makes an
assignment for the benefit of creditors or petitions for or enters into an
arrangement with creditors; or (iv) Tenant shall do or permit to be done
anything which creates a lien upon the Leased Premises for work performed by,
through or under Tenant which Tenant fails to remove or bond off within thirty
(30) days after written notice thereof.

      15.2. Remedies for Tenant's Default.


                                       14
<PAGE>

      (a) Upon the occurrence of any event of default set forth in this Lease,
      Landlord, besides other rights or remedies that it may have and without
      prior notice (except as specified in Subsection 15.1 above), shall have
      the right to (i) terminate Tenant's right of continued possession of the
      Leased Premises and declare the entire remaining unpaid Rent for the
      balance of the then existing Term of this Lease to be immediately due and
      payable forthwith and take action to recover and collect the same either
      by distress or otherwise, but in the event Landlord is able to relet the
      Leased Premises during such periods from time to time, Tenant shall
      consent to such reletting and Tenant shall be entitled to a credit against
      such damages in the amount of the rents and other sums received by
      Landlord from any such reletting of the Leased Premises, less any
      reasonable costs incurred by Landlord in connection with the repossessing
      of the Leased Premises, including, without limitation, reasonable
      attorneys' fees, brokerage commissions and any costs of allowance, repairs
      or alterations, or (ii) terminate this Lease, in which event Tenant shall
      immediately surrender the Leased Premises to Landlord, or (iii) terminate
      Tenant's right of continued possession of the Leased Premises and from
      time to time, without terminating this Lease, relet the Leased Premises or
      any part thereof for the account and in the name of Tenant, for any such
      lease term or terms and conditions as Landlord, in its reasonable
      discretion, may deem advisable, and with the right to make alterations,
      additions and repairs to the Leased Premises deemed by Landlord to be
      necessary in conjunction with such reletting Notwithstanding any other
      remedy set forth in this Lease, in the event Landlord has made rent
      concessions of any type or character, or waived any base rent, and Tenant
      fails to take possession of the Leased Premises on the commencement or
      completion date or otherwise defaults at any time during the term of this
      Lease, the rent concessions, including any waived base rent, shall be
      cancelled and the amount of the base rent or other rent concessions shall
      be due and payable immediately as if no rent concessions or waiver of any
      base rent had ever been granted. A rent concession or waiver of the base
      rent shall not relieve Tenant of any obligation to pay any other charge
      due and payable under this Lease including without limitation any sum due
      under Section 2. Notwithstanding anything contained in this Lease to the
      contrary, this Lease may be terminated by Landlord only by mailing or
      delivering written notice of such termination to Tenant, and no other act
      or omission of Landlord shall be construed as a termination of this Lease.

      (b) Should Landlord terminate Tenant's right of possession of the Leased
      Premises pursuant to Subsection (a) (iii) above, then Tenant shall pay to
      Landlord, within ten (10) days of Landlord's demand, all of the following:
      (i) any unpaid Rent and other charges to be paid by Tenant hereunder up to
      the date when Landlord shall have so terminated Tenants right of
      possession, plus interest thereon at the Default Rate from the due date
      together with the total cost of brokerage commissions and initial
      leasehold or tenant improvements or allowances incurred by Landlord in
      connection with the execution of this Lease (prorated for the unexpired
      portion of the Term); (ii) the reasonable costs of recovering possession
      of the Leased Premises and any reasonable legal fees and expenses directly
      related to the breach, the recovery of possession, and the collection of
      unpaid Rent and other charges; (iii) the reasonable costs incurred by
      Landlord in repairing and restoring the Leased Premises to the condition
      which same were to have been surrendered to Landlord at the expiration of
      the Lease term or to a condition required to lease premises to a new
      tenant; (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); and (v) all reasonable brokerage fees and commissions and
      allowances (prorated for the unexpired portion of the Term) incurred by
      Landlord in reletting the Leased Premises.

      (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. The residue, if any, shall be held by Landlord and applied in
      payment of future rent or damages in the event of termination as the same
      may become due and payable hereunder.

      (d) No such reletting of the Leased Premises by Landlord pursuant to
      Subsection (a)(iii) above shall be construed as an election on its part to
      terminate this Lease unless a notice of such intention be given by
      Landlord to Tenant or unless the termination thereof be decreed by a court
      of competent jurisdiction; and


                                       15
<PAGE>

      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.

      (e) Should Landlord at any time terminate this Lease for any breach
      pursuant to Subsection (a)(ii) above, then in addition to any other remedy
      Landlord may have by reason of such breach, Landlord shall have the right
      to recover from Tenant all or any of the following: (i) any unpaid rent
      and other charges to be paid by Tenant hereunder up to the date of
      termination, plus interest thereon at the Default Rate from the due date;
      (ii) the reasonable costs of recovering possession of the Leased Premises
      and collecting said arrearages in rent and other charges, including any
      reasonable legal fees and expenses directly related to the breach, the
      recovery of possession, and the collection of unpaid Rent and other
      charges to be paid by Tenant and the total cost of brokerage commissions
      and initial leasehold or tenant improvements or allowances incurred by
      Landlord in connection with the execution or renewal of this Lease
      (prorated for the unexpired portion of the Term); (iii) costs, as
      reasonably estimated by Landlord which would be incurred in repairing or
      restoring the Leased Premises to the condition in which the same were to
      have been surrendered to Landlord at the expiration of the Lease term:
      (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.

      (f) Landlord shall have the right to recover, in execution of judgment(s)
      rendered in legal proceedings or otherwise, either jointly or from time to
      time severally, the applicable sums specified in clauses (i)through (v) of
      Subsection (b) and clauses (i) through (vi) of Subsection (e), and
      Landlord's recovery of one or more of such sums shall not constitute a
      waiver of Landlord's right to recover from Tenant the remaining sum(s).

      (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. All of Tenant's and Landlord's obligations under this Section
      shall survive the termination of this Lease.

      (i) Notwithstanding anything herein to the contrary, in the event that
      Tenant abandons the Leased Premises for a continuous period of three weeks
      or more for any reason other than casualty or condemnation or force
      majeure not relating to Tenant's business operations, Landlord shall have
      the sole and exclusive remedy to terminate this Lease without prior
      notice. "Abandon" means the vacating of all or substantially all of the
      Leased Premises by Tenant, whether or not Tenant is in default of the
      rental payments due under this Lease or any other provision of this Lease.

      15.3. Tenant's Bankruptcy. In addition to Landlord's remedies under this
Article 15, Landlord may, at its sole discretion and without notice, invoke the
following provisions:

      (a) Upon a Tenant's bankruptcy, this Lease and all rights of Tenant
      hereunder shall automatically terminate with the same force and effect as
      if the date of any 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. Landlord reserves
      any and all remedies provided herein or at law or in equity


                                       16
<PAGE>

      (b) If this Lease is not terminated in accordance with subsection (a)
      above because such termination is not allowed under the Bankruptcy Code
      (hereinafter defined), upon the filing of a petition by or against Tenant
      under the Bankruptcy Code, Tenant, as debtor and as debtor in possession,
      and any trustee who may be appointed, agree:

            (1) to perform promptly each and every obligation of Tenant under
      this Lease until such time as this Lease is either rejected or assumed by
      order of a United States Bankruptcy Court or other United States Court of
      competent jurisdiction; or deemed rejected by operation of law, pursuant
      to 11 U.S.C. ss. 365(c)(4);

            (2) to pay monthly in advance on the first day of each month as
      reasonable compensation for use and occupancy of the Leased Premises an
      amount equal to all Annual Gross Rent and all other Additional Rent;

            (3) to reject or assume this Lease within sixty (60) days of the
      filing of such petition under Chapter 7 of the Bankruptcy Code or within
      thirty (30) days of the filing of a petition under any other Chapter;

            (4) to give Landlord at least forty-five (45) days prior written
      notice of any proceeding relating to any assumption of this Lease;

            (5) to give Landlord at least thirty (30) days prior written notice
      of any abandonment of the Leased Premises;

            (6) to be deemed conclusively to have rejected this Lease in the
      event of the failure to comply with any of the above;

            (7) to have consented to the entry of an order by an appropriate
      United States Bankruptcy Court providing all of the above, waiving notice
      and hearing of the entry of same; and

            (8) that this is a "lease of real property" as such term is used in
      the Bankruptcy Code.

      (c) Notwithstanding anything in this Lease to the contrary, all amounts
      payable by Tenant to or on behalf of Landlord hereunder, whether or not
      expressly denominated as Rent, shall constitute "rent" for the purposes of
      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. In the event that the
      Bankruptcy Code is interpreted or amended during the term of this Lease to
      so permit, or is superseded by an act so permitting, the following
      additional acts shall be deemed an event of default under this Lease: (i)
      if Tenant is adjudicated insolvent by the United States Bankruptcy Code or
      (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. Landlord reserves any and all rights and
      remedies provided herein or at law.

                      ARTICLE 16. TENANT'S REPRESENTATIONS

      16.1. Tenant's Representations. Tenant, in order to induce Landlord to
enter into this Lease, hereby represents that: Tenant has full power and
authority to conduct its business as presently conducted and to enter into this
Lease; that this Lease has been duly authorized, executed and delivered by
Tenant and constitutes and legal and binding obligation of Tenant; and that no
litigation or proceedings (or threatened litigation or proceeding or basis
therefor) exists which could materially and adversely affect the ability of
Tenant to perform its obligations under this Lease or which would constitute a
default on the part of Tenant under this Lease, or which would constitute such a
default with the giving of notice or lapse of time, or both.

                            ARTICLE 19. MISCELLANEOUS

      19.1. Waiver. Failure of Landlord or Tenant to declare an event of default
immediately upon its occurrence, or delay in taking any action in connection
with an event of default, shall not constitute a waiver of the default, but
Landlord or Tenant shall have the right to declare the default at any time and
take such action as is lawful or authorized under this Lease. 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).

      19.2. Attorney's Fees. 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

the best knowledge, information and belief of the signer of such certificate,
the other party is then in default in performing any of its obligations
hereunder (and, if so, specifying the nature of each such default); and as to
any other fact or condition with respect to this Lease reasonably requested by
the other party hereto or such other addressee, it being intended that any such
statement delivered pursuant to this Section may be relied upon by any
prospective purchaser of the fee or mortgagee or assignee of any mortgage upon
the fee.

            shall survive the expiration of this Lease.

entire term over the rental received by Landlord for the Premises for such term,
which damages shall be payable at such time as said damages as discounted by
agreement of Landlord and Tenant, or by judicial decision, or at such time that

provisions of this Lease required of Tenant hereunder shall not be released or
terminated but shall continue for the remainder of the term of this Lease.

by statue or otherwise, and the exercise or beginning of the exercise by
Landlord of any one or more of the rights or remedies provided for in this Lease
or now or hereafter existing at law or in equity or by statute or otherwise
shall not preclude the simultaneous or later exercise by Landlord of any or all
other rights or remedies provided for in this Lease or now or hereafter existing
at law or in equity or by statute or otherwise. In the event of a default or
threatened default by Tenant of any of the terms, provisions, covenants,
conditions, rules and regulations of this Lease, Landlord shall have the right

in equity.

any deed of trust, mortgage or mortgages now or hereafter placed upon Landlord's
interest in the Premises; provided, however, that Landlord shall procure from

provides in substance that so long as Tenant substantially performs the
obligations imposed upon Tenant hereunder within the applicable grace or cure
period, its tenancy will not be

written notice to Tenant.

      17.2 Waivers. Failure of either party to complain of any act or omission

provision of this Lease shall be deemed a waiver of a breach of any other
provisions of this Lease or a consent to any subsequent breach of the same or

approval of the other party, the other party's consent to or approval of such
action on any one occasion shall not be deemed a consent to or approval of said

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-
<PAGE>

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-
<PAGE>

      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-
<PAGE>

      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-
<PAGE>

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


                                      -6-
<PAGE>

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-
<PAGE>

      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-
<PAGE>

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.

      31. Special Stipulations. In so far as the following stipulations conflict
with any of the foregoing provisions, the following shall control:

parties hereto; and no representations, inducements, promises or agreements,
oral or otherwise between the parties and not embodied herein shall be of any
force or effect.

      33. Lease Contingent Upon Simultaneous Closing. This lease is void unless

                              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.
<PAGE>

            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-
<PAGE>

                        (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-
<PAGE>

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-
<PAGE>

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.

                  (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-
<PAGE>

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.

            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-
<PAGE>

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-
<PAGE>

                  (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-
<PAGE>

            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-

                              EMPLOYMENT AGREEMENT

            THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into
this 13 day of February, 1998, by and between REGENERATION TECHNOLOGIES, INC., a
Florida corporation (the "Corporation") and RICHARD R. ALLEN ("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 Chief Financial Officer. 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.

<PAGE>

            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 Twenty-Five Thousand
Dollars ($125,000.00) 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 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;

                        (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 One Hundred Twenty Thousand (120,000) 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, subject always to the rules in effect regarding participation in
such plans. 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.

<PAGE>

            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. 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 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



                                     - 4 -
<PAGE>

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
      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


                                     - 5 -
<PAGE>

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 effective date of
termination, and shall, in such event, be paid the compensation due Employee
hereunder for the remainder of such period.

            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


                                     - 6 -
<PAGE>

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. 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


                                     - 7 -
<PAGE>

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 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, 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 -
<PAGE>

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. For purposes of this Agreement, the "Southeastern United States" shall
include the following states: Florida, Georgia, Alabama, Mississippi, South
Carolina, North Carolina, Tennessee, Kentucky and Virginia.

                  (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


                                     - 9 -
<PAGE>

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.

            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:


                                     - 10 -

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

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
$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.

            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


                                     - 11 -

                              EMPLOYMENT AGREEMENT

      THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered in this
25th day of November, 1998, by and between REGENERATION TECHNOLOGIES, INC., a
Florida corporation (the "Corporation") having its principal address at 2

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

subject to such vesting and other requirements as are set forth in the Omnibus

entitled to all fringe benefits offered generally to the Corporation's

            10. Termination of Employment.

            (a) Voluntary Termination. Employee or the Corporation may
voluntarily terminate Employee's employment with the Corporation (and, expect 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
<PAGE>

Subj: Employment Agreement ICO Frederick Preiss

                  (vii) Failure to properly perform Employee's duties;

                  (viii) Use of alcohol or narcotics to the extent it prevents,
in the sole judgement of the Corporation's Board of Directors, Employee from
effectively performing the duties set forth in Paragraph I above;

                  (ix) Violating the covenants set forth in Paragraph 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.

            (c) Termination Upon Death, Incompentency or Disability.
Notwithstanding Subparagraph 9(a) above, the Corporation shall have the right to
terminate Employee's employment with the Corporation (and, expect as otherwise
specifically provided hereunder, this Agreement) immediately and without prior
written notice to Employee in the event that the Employee dies, or is
adjudicated incompetent, or is "permanently disabled", as hereinafter denied. 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


                                       6
<PAGE>

Subj: Employment Agreement ICO Frederick Preiss

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.

            11. 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


                                       7
<PAGE>

Subj: Employment Agreement ICO Frederick Preiss

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) 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.

            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 ("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 that are the property of the Corporation 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 further agrees that
upon the termination of her employment with the Corporation for any reason
whatsoever, Employee shall immediately deliver and surrender to


                                       8
<PAGE>

Subj: Employment Agreement ICO Frederick Preiss

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.

            (b) 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 or be employed by any business which engages in the
business of manufacturing or distributing products from bone tissue within the
United States. In the event Employee is terminated by the Corporation without
cause, the Corporation will provide severance compensation to Employee as
follows:

                  (1) The Corporation provides no severance compensation in the
event of termination prior to the end of four (04) months of full time
employment;

                  (2) The Corporation provides one month of basic annual salary
if Employee has served five months of full time employment upon termination.

            (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

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. 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.

                              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.


<PAGE>

      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;

<PAGE>

                  (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

            (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-
<PAGE>

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. 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

      9. Termination of Employment.


                                      -4-
<PAGE>

            (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.

<PAGE>

                  (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.

                  (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 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


                                      -6-
<PAGE>

effective date of termination, and shall, in such event, be paid the
compensation due Employee hereunder for the remainder of such period.

      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


                                      -7-
<PAGE>

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"). 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 to the Corporation and he will cooperate with the
Corporation in connection with any patent applications. In this regard,


                                      -8-
<PAGE>

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. 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 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; provided, however, that
Employee shall then be entitled to a severance payment in the amount of one-half
(1/2) his then current annual salary (computed without reference to shares of
stock in the Corporation, fringe benefits, or any other form of compensation).
The


                                      -9-
<PAGE>

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
- -----------------        -------------------------------     ----------------

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

0-3 months               none                                none

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



                                      -10-
<PAGE>

      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. 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.


                                      -11-
<PAGE>

            (f) 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.

and the termination of Employee's employment with the Corporation.

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, 1] 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;


                                      -12-
<PAGE>

            (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.

      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. Attorneys 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 included 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

                              EMPLOYMENT AGREEMENT

      THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered in this

            10. Termination of Employment.

            (a) Voluntary Termination. Employee or the Corporation may
voluntarily terminate Employee's employment with the Corporation (and, expect 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
<PAGE>

Subj: Employment Agreement ICO James P. Abraham


                  (vii) Failure to properly perform Employee's duties;

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

                  (ix) Violating the covenants set forth in Paragraph 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.

            (c) Termination Upon Death, Incompentency or Disability.
Notwithstanding Subparagraph 9(a) above, the Corporation shall have the right to
terminate Employee's employment with the Corporation (and, expect as otherwise
specifically provided hereunder, this Agreement) immediately and without prior
written notice to Employee in the event that the Employee dies, or is
adjudicated incompetent, or is "permanently disabled", as hereinafter denied. 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


                                       6
<PAGE>

Subj: Employment Agreement ICO James P. Abraham

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.

            11. 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


                                       7
<PAGE>

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) 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.

            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 ("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 that are the property of the Corporation 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 further agrees that
upon the termination of her employment with the Corporation for any reason
whatsoever, Employee shall immediately deliver and surrender to


                                       8
<PAGE>

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.

                  (b) 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 or be employed by any business which engages in the
business of manufacturing or distributing products from bone tissue within the
United States. In the event Employee is terminated by the Corporation without
cause, the Corporation will provide severance compensation to Employee as
follows:

                        (1) The Corporation provides no severance compensation
in the event of termination prior to the end of four (04) months of full time
employment;

                        (2) The Corporation provides one month of basic annual
salary if Employee has served four months of full time employment upon
termination.

months of employment, to be paid monthly;

                        (6) The Corporation provides Employee five (5) months of
basic annual salary if Employee has served at least (10) months of employment

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.

                  (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

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

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

(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

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.

                              EMPLOYMENT AGREEMENT

            THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into
by and between REGENERATION TECHNOLOGIES, INC. a Florida for-profit corporation
(the "Corporation") and NANCY R. HOLLAND ("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 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-

<PAGE>

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;

<PAGE>

                        (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-
<PAGE>

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-
<PAGE>

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-
<PAGE>

                        (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.

            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-
<PAGE>

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-
<PAGE>

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-
<PAGE>

                  (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-
<PAGE>

                  (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-
<PAGE>

                  (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.

            18. 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


                                      -12-

"Administrator").

      (b) Powers of the Administrator. The Administrator shall have all the
powers vested in it by the terms of the Plan, such powers to include authority,
in its sole and absolute discretion, to grant Awards under the Plan, prescribe

Awards.

      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

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

condition with

<PAGE>

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

concerned, including the Corporation, its stockholders, any participants in the
Plan and any other employee of the Corporation, and their respective successors
in interest.

      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-
<PAGE>

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-
<PAGE>

      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-
<PAGE>

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.

Sales & Marketing Plan:

The following employees are participants in the Sales & Marketing Plan.

              Participants -
                  VP Sales

                  Distribution Manager
                  Oral-Maxillofacial Group

How Sales & Marketing Plan awards are computed:

The Sales & Marketing Plan establishes, for each product group under the
employee's control:

      o     Baseline sales volumes
      o     "Budget" sales volumes (external goals)
      o     "Internal Target" sales volumes (optimistic goals)

For each product group, the potential award is calculated as a pre-determined
percentage of the sales over baseline and over Budget.

VP and Director-level participants in the Sales & Marketing Plan, like Officer &
Director-level participants in the RTI Corporate Plan, do not achieve any awards
unless sales equal to the "Budget" levels are achieved.

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.

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

Discounts:

      In all lines where previous sales history exists, the average discount
      must be maintained in order to achieve the above bonuses.

      If the average sales in any quarterly period are at a discount greater
      than the average, 2.5% of the bonus will be lost for each 1% discount off
      average.

      If the average sales in any quarterly period are 5% or more ABOVE the
      average, the bonus will be increased by 10% (new bonus will = 110% x
      normal bonus).

      The term "average discount" means the average discount off of catalog
      pricing within the region for the preceding 6-month period.
