provided hereunder, this Agreement) immediately and without prior written notice
to the Employee as required by paragraph "a" above in the event that the
Employee dies, is adjudicated incompetent, or is permanently disabled, as
defined by this Agreement. In this Agreement, the term permanently disabled
shall mean that the Employee is unable to perform adequately his or her regular
duties under this Agreement as a result of sickness or accident and such health
condition appears to be permanent. The determination of permanent disability
shall be made at the sole discretion of Regeneration Technologies' President and

client information; the existence of negotiations with prospective clients of
Regeneration Technologies; marketing data and plans; financial information and
financial data not publicly disclosed; all drawings, records, sketches, and
models; trade secrets and trade secrets relating to services of Regeneration
Technologies; and, products being developed by Regeneration Technologies
("Confidential Information").

     Employee also acknowledges, recognizes and understands that Regeneration
Technologies owns or has access to various types of intellectual property that
are protected or may be protected by copyright, trademark, patent, trade secret,
or other laws. The types of intellectual property that are considered

                                       8
<PAGE>

Technologies under confidentiality agreements ("Intellectual Property").

     The Employee acknowledges and agrees that the maintenance of the
confidentiality of the Confidential Information and Intellectual Property and
restrictions on the use of the Confidential Information and Intellectual
Property is essential to Regeneration Technologies.

     The provisions of this Paragraph 6 shall survive the termination of
Employee's employment with Regeneration Technologies.

     7. NON-DISCLOSURE OF CONFIDENTIAL INFORMATION AND INTELLECTUAL PROPERTY.

     The Employee shall not, during or after the termination of his or her
employment with Regeneration Technologies: (a) directly or indirectly publish,
disclose, reproduce, record, make facsimiles of, abstract, summarize, remove,
make accessible, or misappropriate any Confidential Information or Intellectual
Property as defined under this Agreement, to any person (including family
members and friends), firm, corporation, or association or other entity,
competitor or third party, for any reason whatsoever; or, (b) use, keep, or
otherwise deal in or with such Confidential Information or Trade Secrets, except
during employment with Regeneration Technologies and for the benefit of
Regeneration Technologies, without prior written permission of the President and
CEO of Regeneration Technologies. The Employee agrees not to disclose any

                                       9
<PAGE>

Regeneration Technologies unless authorized by the President and CEO of
Regeneration Technologies.

     All of the Confidential Information or Intellectual Property listed in
Paragraph number six (6) above is, and shall remain, the exclusive property of
Regeneration Technologies, and shall not be removed from Regeneration
Technologies' premises, without the prior written consent of the President and
CEO of Regeneration Technologies. The Employee shall return all Confidential
Information and Intellectual Property described in Paragraph number six (6)
prior to or at the termination of his or her employment with Regeneration
Technologies. The Employee agrees that he is under no obligation to any former
employer which is in any way inconsistent with this Agreement or which imposes
any restriction on behalf of Regeneration Technologies or the Employee. The
Employee also acknowledges that he has been instructed by Regeneration
Technologies that during his employment with Regeneration Technologies, he is
not to divulge to Regeneration Technologies, its employees, or its consultants,
any confidential information or intellectual property obtained by the Employee
from any previous employers, entities, or persons. The provisions of this

Regeneration Technologies and the termination of this Agreement.

     8. IRREPARABLE HARM.

     The Employee acknowledges and agrees that any disclosure of

                                       10
<PAGE>

Confidential Information and Intellectual Property delineated in paragraph
number six (6) by the Employee would cause severe and irreparable harm to
Regeneration Technologies. In the event there is a breach or a threatened breach
by the Employee of the Non-Disclosure provisions of this Agreement, Regeneration
Technologies shall be entitled to an injunction restraining the Employee from
disclosing, in whole or in part, such Confidential Information and Intellectual
Property or from rendering a service to any person, firm, corporation,
association, or other entity, to whom such information has been disclosed and to
recover all costs of pursuing such remedy, including reasonable attorneys' fees,
costs, and expenses. Nothing in this Agreement shall be construed as prohibiting
Regeneration Technologies from pursuing other remedies as may be available to it
for the Employee's breach or threatened breach, including recovery of damages
from the Employee. The provisions of this Paragraph 8 shall survive the
termination of Employee's employment with Regeneration Technologies and the
termination of this Agreement.

     9. EMPLOYEE DEVELOPMENTS.

     The Employee is aware and understands that during the term of the
Employee's employment with Regeneration Technologies or with the financial and
other assistance that may be provided by Regeneration Technologies, the Employee

not limited to, patents, trademarks, inventions, other patentable

                                       11
<PAGE>

inventions and other trade secrets and formula ("Employee Developments"). The
Employee agrees that all Employee Developments that may be developed or produced
by the Employee during the Employee's employment by Regeneration Technologies
are and will be the property of Regeneration Technologies and that the Employee
further agrees that he will, at the request of Regeneration Technologies,
execute such documents Regeneration Technologies 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 Regeneration Technologies to
Regeneration Technologies and he will cooperate with Regeneration Technologies
in connection with any patent applications. In this regard, the Employee will,
at all times, fully advise and inform Regeneration Technologies of all matters
that the Employee may be developing or working on while employed by Regeneration
Technologies. The Employee further agrees that upon the termination of his or
her employment with Regeneration Technologies for any reason whatsoever, the
Employee shall immediately deliver and surrender to Regeneration Technologies
any and all plans, documents and other materials of any nature relating to the

compensation to the Employee as consideration for Employee Developments in
accordance with any patent policy of Regeneration Technologies. The provisions
of this Paragraph 9 shall survive the termination of Employee's employment with
Regeneration

                                       12
<PAGE>

Technologies and the termination of this Agreement.

     10. NON-COMPETITION.

     In the event of the termination of the Employee's employment with
Regeneration Technologies either by Regeneration Technologies for cause or
voluntarily by the Employee, the Employee agrees that for a period of two (2)
years following the effective date of the termination, the Employee will not
engage in or be associated with or employed by any "Licensed Tissue Bank"
organization, which engages in the business of recovery, procurement,
manufacturing, or distributing products from bone tissue in the United States.
The Licensed Tissue Bank organizations that Employee specifically agrees not to
become employed by or in any way associate with for a two (2) year period
following the effective date of Employee's termination are as follows:
Musculoskeletal Transplant Foundation; CryoLife; LifeCell; Allosource; Tissue
Banks International; Osteotech, Inc.; LifeLink Tissue Bank; Life Net; Community
Tissue Services; American Red Cross; BioGenetics; and, Cryogenic. The Employee
also agrees that for a two (2) year period following the effective date of
Employee's termination not to participant in, assist with or in any become
associated with or employed by any new start up venture engaged in the business
of a Licensed Tissue Bank. This limitation of employment excludes any and all
non-biologic implantable medical devices.

     This non-compete is valid only if employee is terminated for cause or

                                       13
<PAGE>

voluntarily terminates his employment.

     In the event the employee is terminated 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 harvests or delivers human tissue
or products derived from human tissue within the Corporation's service area;
provided, however, that Employee shall then be entitled to a severance payment
in the amount of six (6) months salary (computed without reference to fringe
benefits, bonuses, or any other form of compensation and subject to applicable
taxes). The Corporation may require the Employee to execute a release of claims
against the Corporation as a condition precedent to its obligation to make the
severance payment described herein.

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

     The Employee recognizes that Regeneration Technologies would not sign this
Agreement without the inclusion of this covenant, and the Employee confirms

                                       14
<PAGE>

the sufficiency of the consideration received by the Employee, in the form of
employment or continued employment by Regeneration Technologies, in accepting
this covenant as a material term of this Agreement. The provisions of this
Paragraph 10 shall survive the termination of Employee's employment with
Regeneration Technologies and the termination of this Agreement.

     11. NON-SOLICITATION.

     The Employee agrees during his employment with Regeneration Technologies,
and for a period of two (2) years from the termination date of his employment
with Regeneration Technologies, not to: (a) engage, hire, employ, or solicit any
employee of Regeneration Technologies, or any subsidiary or affiliate of
Regeneration Technologies, or otherwise induce or attempt to induce any employee
of Regeneration Technologies to leave the employment of Regeneration
Technologies; or (b) directly or indirectly attempt to solicit any client or
customer of Regeneration Technologies, or any client or customer of any
subsidiary or affiliate of Regeneration Technologies, or directly or indirectly
interfere with Regeneration Technologies' relationship, or any subsidiary's or
affiliate's relationship, with any of its clients or customers. The provisions
of this Paragraph 11 shall survive the termination of Employee's employment with
Regeneration Technologies and the termination of this Agreement.

     12. REMEDIES FOR BREACH OF LIMITATION OF EMPLOYMENT AND NON-SOLICITATION.

     It is understood and agreed by the Parties that Regeneration Technologies

                                       15
<PAGE>

shall be entitled, upon application to a court of competent jurisdiction, to
obtain injunctive relief to enforce the provisions of Paragraphs 10 and 11,
which injunctive relief shall be in addition to any other rights or remedies
available to Regeneration Technologies. If such a violation occurs, the Employee
shall be responsible for the payment of reasonable attorneys' fees and other
costs and expenses incurred by Regeneration Technologies in enforcing the
covenants contained in Paragraphs 10 and 11, whether incurred at the trial level
or in any appellate proceeding.

     13. NON-DISPARAGEMENT.

     While employed by Regeneration Technologies or any affiliate of
Regeneration Technologies and after the Employee's employment terminates for
whatever reason, the Employee agrees not to disparage, denigrate, or comment
negatively upon, either orally or in writing, Regeneration Technologies, or any
of its affiliates, officers, or directors, to or in the presence of any person
or entity.

     14. INVALID PROVISION.

     In the event any provision of this Agreement should be or become invalid or
unenforceable, the invalid provision shall not affect the validity and
enforceability of any other provision of this Agreement. Similarly, if the scope
of any restriction or covenant contained in this Agreement should be or become
too broad or extensive to permit enforcement of the covenant or provision to its
full extent, then any restriction or covenant shall be enforced to the maximum
extent

                                       16
<PAGE>

permitted by law. The Employee consents and agrees that the scope of any
restriction or covenant may be modified accordingly in any judicial proceeding
brought to enforce the restriction or covenant.

     15. MEDIATION.

     The Parties acknowledge and agree that in the event that a dispute arises
between Regeneration Technologies and the Employee pertaining to the employment
provisions of this Agreement (paragraphs 1, 2, 3, 4, and 5), the Parties agree
to mediate the dispute within thirty (30) days of the dispute and prior to
either of the Parties instituting a lawsuit under the Agreement. The Parties
agree to mutually select and agree upon a mediator and to split the costs and
expenses equally associated with the mediation. If either of the Parties fail to
agree to or hinder the mediation process, such conduct shall be a breach of this
Agreement.

     16. DISPUTES, ATTORNEY'S FEES, COSTS AND EXPENSES.

     Except as provided in paragraphs 8 and 12 above, in the event a dispute
arises between the Parties and a 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 non-prevailing party, whether incurred at the
trial level or in any appellate proceeding. In addition, each party, to the
fullest extent permitted by applicable law, irrevocably waives all right to a
trial by jury as to any issue in any action, proceeding or counterclaim arising
out of this Agreement.

agreement regarding the subject matter of this Agreement has been made to or
with the Employee that is not provided for in this Agreement. This Agreement
represents the complete Agreement between Regeneration Technologies and the
Employee regarding the subject matter of this Agreement. Any representations or

assignee of The University of Florida Tissue Bank, Inc. ("UFTB"), and Medtronic
Sofamor Danek, Inc. ("MSD"), formerly Sofamor Danek Group, Inc. ("SDG") in which
the parties agree as follows:

1.   RTI is distributing products comprising Bone Paste that may be used by
     RTI's customers in the Field of Use in the Territory. The parties
     acknowledge the unique challenges posed by RTI's marketing/distribution of
     Bone Paste products and therefore have agreed to amend the Agreement as
     amended by the First Amendment, as set forth in this Second Amendment. RTI
     and MSD agree that amendments made herein constitute mutual consideration.
     The amendments set forth herein shall be effective on the Second Amendment
     Effective Date. The parties agree to:

     a.   Add the following new paragraph to Section 3.2 of the Agreement:

          (f)  OTHER BONE PASTE PRODUCTS. RTI distributes UFTB Paste Products
               that comprise Bone Paste as described in Schedule A ("Other Paste
               Products"). Because such Other Pasta Products may be used in the
               Field of Use, RTI agrees that, as of the Second Amendment
               Effective Date, regardless of which party receives customer
               requests for UFTB Paste Products or Other Paste Products and
               regardless of whether the intended use is or is not in the Field
               of Use, all such customer requests will be referred to MSD. The
               terms of Article 3.1 hereof relating to customers and customer
               instructions, the facilitation of shipments, UFTB Customers and
               UFTB Customer instructions shall remain in full force and effect
               as to UFTB Paste Products and Other Paste Products.

     b.   Delete Sections 3.4(a)(i) and (ii) as provided in the First Amendment
          and substitute therefore the following:

          (i)  As of the Second Amendment Effective Date, the Management
               Services Fee shall be fifty-four percent (54%) of the actual net
               invoiced amount (as determined in accordance with Section 3.4(c))
               from RTI to UFTB Customers and to customers for Other Paste
               Products pursuant to this Agreement.

     c.   Renumber Section 3.4(iii) in the First Amendment to 3.4(ii)

                                       21

2.   Either pony may terminate this Second Amendment, for any reason whatsoever,
     upon 180 days written notice to the other party. As of the effective date
     of any such termination, the terms and conditions of the Agreement as
     amended by the First Amendment shall control, and this Second Amendment
     shall be of no further force or effect.

3.   The term of the Agreement as amended by the First Amendment shall remain as
     set forth in Section 5.1 thereof.

4.   Except as modified by this Second Amendment, all terms, conditions and
     definitions contained in the Agreement and First Amendment are ratified and
     confirmed.

     IN WITNESS WHEREOF, the parties have caused this Second Amendment to be
executed by their duly authorized representatives.
