Principal Amount: $6,000,000.00     Initial Rate: 6.881%      Date of Note:
                                                              September 24, 1999

PROMISE TO PAY. Regeneration Technologies, Inc. ("Borrower") promises to pay
to Bank of America, N.A. ("Lender"), or order, in lawful money of the United
States of America, the principal amount of Six Million & 00/100 Dollars
($6,000,000.00) or so much as may be outstanding, together with interest on
the unpaid outstanding principal balance of each advance. Interest shall be
calculated from the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in one payment of all outstanding
principal plus all accrued unpaid interest on September 24, 2000. In
addition, Borrower will pay regular monthly payments of accrued unpaid
interest beginning October 24, 1999, and all subsequent interest payments are
due on the same day of each month after that. The annual interest rate for
this Note is computed on a 365/360 basis; that is, by applying the ratio of
the annual interest rate over a year of 360 days, multiplied by the
outstanding principal balance, multiplied by the actual number of days the
principal balance is outstanding. Borrower will pay Lender at Lender's
address shown above or at such other place as Lender may designate in
writing. Unless otherwise agreed or required by applicable law, payments will
be applied first to any unpaid collection costs and any late charges, then to
any unpaid interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change
from time to time based on changes in an independent index which is the "Wall
State Journal LIBOR Rate" which is a fluctuating rate of interest equal to
the 1 month London interbank offered rate as published in the "Money Rates"
section of The Wall Street Journal on the immediately preceding business day
as adjusted from time to time in Lender's sole discretion for then applicable
reserve requirements, deposit insurance assessment rates and other regulatory
costs (the "Index"). The Index is not necessarily the lowest rate charged by
Lender on its loans. If the index becomes unavailable during the term of this
loan, Lender may designate a substitute index after notice to Borrower.
Lender will tell Borrower the current index rate upon Borrower's request.
Borrower understands that Lender may make loans based on other rates as
well. The interest rate change will not occur most often than each date of
such change in the Index. The Index currently is 5.381% per annum. The
interest rate to be applied to the unpaid principal balance of this Note will
be at a rate of 1.500 percentage points over the index, resulting in an
initial rate of 6.881% per annum. NOTICE: Under no circumstances will the
effective rate of interest on this Note be more than the maximum rate allowed
by applicable law.

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount
owed earlier than it is due. Early payments will not, unless agreed to by
Lender in writing, relieve Borrower of Borrower's obligation to continue to
make payments of accrued unpaid interest. Rather, they will reduce the
principal balance due.

LATE CHARGE. If a payment is 15 days or more late, Borrower will be charged
4.000% of the unpaid portion of the regularly scheduled payment.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform
when due any other term, obligation, covenant, or condition contained in this
Note or any agreement related to this Note, or in any other agreement or loan
Borrower has with Lender. (c) Any representation or statement made or
furnished to Lender by Borrower or on Borrower's behalf is false or
misleading in any material respects either now or at the time made or
furnished. (d) Borrower becomes insolvent, a receiver is appointed for any
part of Borrower's property. Borrower makes an assignment for the benefit of
creditors, or any proceeding is commenced either by Borrower or against
Borrower under any bankruptcy or insolvency laws. (e) Any creditor tries to
take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with
Lender. (f) Any guarantor dies or any of the other events described in this
default section occurs with respect to any guarantor of this Note. (g) A
material adverse change occurs in Borrower's financial condition, or Lender
believes the prospect of payment or performance of the indebtedness is
impaired. (h) Lender in good faith deems itself insecure.

LENDER's RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. This Note has been delivered
to Lender and accepted by Lender in the State of Florida. If there is a
lawsuit, Borrower agrees upon Lender's request to submit to the jurisdiction
of the courts of Duval County, the State of Florida. This Note shall be
governed by and construed in accordance with the laws of the State of Florida.

RIGHT OF SETOFF. Borrower grants to Lender a contractual security interest
in, and hereby assigns, conveys, delivers, pledges, and transfers to Lender
all Borrower's right, title and interest in and to, Borrower's accounts with
Lender (whether checking, savings, or some other account), including without
limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA and Keogh
accounts, and all trust accounts for which the grant of a security interest
would be prohibited by law. Borrower authorizes Lender, to the extent
permitted by applicable law, to charge or setoff all sums owing on this Note
against any and all such accounts, and, at Lender's option, to
administratively freeze all such accounts to allow Lender to protect Lender's
charge and setoff rights provided on this paragraph.

LINE OF CREDIT. This Note evidences a revolving line of credit. Advances
under this Note, as well as directions for payment from Borrower's accounts,
may be requested orally or in writing by Borrower or by an authorized person.
Lender may, but need not, require that all oral requests be confirmed in
writing. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to
any of Borrower's accounts with Lender. The unpaid principal balance owing on
this Note at any time may be evidenced by endorsements on this Note or by
Lender's internal records, including daily computer print-outs. Lender will
have no obligation to advance funds under this Note if: (a) Borrower or any
guarantor is in default under the terms of this Note or any agreement that
Borrower or any guarantor has with Lender, including any agreement made in
connection with the signing of this Note; (b) Borrower or any guarantor
ceases doing business or is insolvent; (c) any guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such guarantor's guarantee of
this Note or any other loan with Lender; (d) Borrower has applied funds
provided pursuant to this Note for purposes other than those authorized by
Lender; or (e) Lender in good faith deems itself insecure under this Note or
any other agreement between Lender and Borrower.

ARBITRATION. Any claim or controversy ("Claim") between the parties,
whether arising in contract or tort or by statute including, but not limited
to. Claims resulting from or relating to this Agreement shall, upon the
request of either party, be resolved by arbitration in accordance with the

===============================================================================

J.A.M.S./Endispute. The arbitration shall be conducted in any state where
real or personal property collateral for the credit is located or if there is
no collateral, in the state of any Borrower's domicile at the time of the
execution of this Agreement or at the commencement of any arbitration
proceeding. The arbitration hearing shall commence within 90 days of the
demand for arbitration and close within 90 days of commencement, and any
award, which may include legal fees, shall be issued (with a brief written
statement of the reasons therefore) within 30 days of the close of hearing.
Any dispute concerning whether a claim is arbitrable or barred by the statute
of limitations shall be determined by the arbitrator. This arbitration
provision is not intended to limit the right of any party to exercise
self-help remedies, to seek and obtain interim or provisional relief of any
kind or to initiate judicial or non-judicial foreclosure against any real
or personal property collateral.

DEFAULT INTEREST RATE. Upon default under this Note, including failure to pay
upon final maturity, to the extent permitted by law, the rate of interest on
the unpaid principal shall be increased at Lender's discretion up to the
maximum rate allowed by law, or if not, 25% per annum.

NON-USAGE FEE. A non-refundable, non-proratable fee of .25% per annum of the
unused portion of the original principal amount of this Note shall be due and
payable annually, in arrears, commencing September 24, 1999. This fee may be
modified from time to time by Lender upon prior written notice to Borrower.

GENERAL PROVISIONS. If any part of this Note cannot be enforced, this fact
will not affect the rest of the Note. Borrower does not agree or intend to
pay, and Lender does not agree or intend to contract for, charge, collect,
take, reserve or receive (collectively referred to herein as "charge or
collect"), any amount in the nature of interest or in the nature of a fee for
this loan, which would in any way or event (including demand, prepayment, or
acceleration) cause Lender to charge or collect more for this loan than the
maximum Lender would be permitted to charge or collect by federal law or the
law of the State of Florida (as applicable). Any such excess interest or
unauthorized fee shall, instead of anything stated to the contrary, be
applied first to reduce the principal balance of this loan, and when the
principal has been paid in full, be refunded to Borrower. Lender may delay or
forgo enforcing any of its rights or remedies under this Note without losing
them. Borrower and any other person who signs, guarantees or endorses this
Note, to the extent allowed by law, waive presentment, demand for payment,
protest and notice of dishonor. Upon any change in the terms of this Note,
and unless otherwise expressly stated in writing, no party who signs this
Note, whether as maker, guarantor, accommodation maker or endorser, shall be
released from liability. All such parties agree that Lender may renew or
extend (repeatedly and for any length of time) this loan, or release any
party or guarantor or collateral; or impair, fail to realize upon or perfect
Lender's security interest in the collateral; and take any other action
deemed necessary by Lender without the consent of or notice to anyone. All
such parties also agree that Lender may modify this loan without the consent
of or notice to anyone other than the party with whom the modification is
made.

PRIOR TO SIGNING THIS NOTE, BORROWER READ AND UNDERSTOOD ALL THE PROVISIONS
OF THIS NOTE, INCLUDING THE VARIABLE INTEREST RATE PROVISIONS. BORROWER
AGREES TO THE TERMS OF THE NOTE AND ACKNOWLEDGES RECEIPT OF A COMPLETED COPY

     statement which Borrower deems to be incorrect.

     expenses for the perfection, termination, and the continuation of the

     account or lock box arrangement with Lender, or Lender's agent, or with one
     or more financial institutions designated by Lender. Borrower further
     agrees that, if no Event of Default exists under this Agreement, any and

     for the benefit of Borrower (which deposit accounts shall be subject to a

     accounts shall likewise be subject to a security assignment in favor of

     compliance of the properties with this section of the Agreement. Any
     inspections or tests made by Lender shall be at Borrower's expense and for

     waste and hazardous substances. Borrower hereby (a) releases and waives any

     in the ordinary course of business and for which adequate reserves have

     superior to Lender's Security Interests and rights in and to such
     Collateral.

     or indirectly securing repayment of Borrower's Loan and Note and all of the
     Related Documents are binding upon Borrower as well as upon Borrower's

of an Event of Default of the type described in the "Insolvency" subsection
above, such acceleration shall be automatic and not optional. In addition,

Documents or available at law, in equity, or otherwise. Except as may be
prohibited by applicable law, all of Lender's rights and remedies shall be
cumulative and may be exercised singularly or concurrently. Election by
Lender to pursue any remedy shall not exclude pursuit of any other remedy,
and an election to make expenditures or to take action to perform an
obligation of Borrower or of any Grantor shall not affect Lender's right to

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part
of this Agreement:

     AMENDMENTS.  This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to
     the matters set forth in this Agreement. No alteration of or amendment
     to this Agreement shall be effective unless given in writing and signed
     by the party or parties sought to be charged or bound by the alteration
     or amendment.

     APPLICABLE LAW.  This Agreement has been delivered to Lender and
     accepted by Lender in the State of Florida. If there is a lawsuit,
     Borrower agrees upon Lender's request to submit to the jurisdiction of
     the courts of Duval County, the State of Florida. This Agreement shall
     be governed by and construed in accordance with the laws of the State of
     Florida.

     CAPTION HEADINGS.  Caption headings in this Agreement are for
     convenience purposes only and are not to be used to interpret or define
     the provisions of this Agreement.

     CONSENT TO LOAN PARTICIPATION.  Borrower agrees and consents to Lender's
     sale or transfer, whether now or later, of one or more participation
     interests in the Loans to one or more purchasers, whether related or
     unrelated to Lender. Lender may provide, without any limitation
     whatsoever, to any one or more purchasers, or potential purchasers, any
     information or knowledge Lender may have about Borrower or about any
     other matter relating to the Loan, and Borrower hereby waives any rights
     to privacy it may have with respect to such matters. Borrower
     additionally waives any and all notices of sale of participation
     interests, as well as all notices of any repurchase of such
     participation interests. Borrower also agrees that the purchasers of any
     such participation interests will be considered as the absolute owners
     of such interests in the Loans and will have all the rights granted
     under the participation agreement or agreements governing the sale of
     such participation interests. Borrower further waives all rights of
     offset or counterclaim that it may have now or later against Lender or
     against any purchaser of such a participation interest and
     unconditionally agrees that either Lender or such purchaser may enforce
     Borrower's obligation under the Loans irrespective of the failure or
     insolvency of any holder of any interest in the Loans. Borrower further
     agrees that the purchaser of any such participation interests may
     enforce its interests irrespective of any personal claims or defenses
     that Borrower may have against Lender.

     COSTS AND EXPENSES.  Borrower agrees to pay upon demand all of Lender's
     expenses incurred in connection with the preparation, execution,
     enforcement, modification and collection of this Agreement or in
     connection with the Loans made pursuant to this Agreement. Lender may
     pay someone else to help collect the Loans and to enforce this
     Agreement, and Borrower will pay that amount. This includes, subject to
     any limits under applicable law, Lender's legal expenses, whether or not
     there is a lawsuit, including expenses for bankruptcy proceedings
     (including efforts to modify or vacate any automatic stay or injunction),
     appeals, and any anticipated post-judgment collection services. Borrower
     also will pay any court costs, in addition to all other sums provided by
     law.

     NOTICES.  All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimile (unless otherwise
     required by law), and shall be effective when actually delivered or when
     deposited with a nationally recognized overnight courier or deposited in
     the United States mail, first class, postage prepaid, addressed to the
     party to whom the notice is to be given at the address shown above. Any
     party may change its address for notices under this Agreement by giving
     formal written notice to the other parties, specifying that the purpose
     of the notice is to change the party's address. To the extent permitted
     by applicable law, if there is more than one Borrower, notice to any
     Borrower will constitute notice to all Borrowers. For notice purposes,
     Borrower will keep Lender informed at all times of Borrower's current
     address(es).

     SEVERABILITY.  If a court of competent jurisdiction finds any provision
     of this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances. If feasible, any
     such offending provision shall be deemed to be modified to be within
     the limits of enforceability or validity; however, if the offending
     provision cannot be so modified, it shall be stricken and all other
     provisions of this Agreement in all other respects shall remain valid
     and enforceable.

     SUBSIDIARIES AND AFFILIATES OF BORROWER.  To the extent the context of
     any provisions of this Agreement makes it appropriate, including without
     limitation any representation, warranty or covenant, the word "Borrower"
     as used herein shall include all subsidiaries and affiliates of Borrower.
     Notwithstanding the foregoing however, under no circumstances shall this
     Agreement be construed to require Lender to make any Loan or other
     financial accommodation to any subsidiary or affiliate of Borrower.

     SUCCESSORS AND ASSIGNS.  All covenants and agreements contained by or on
     behalf of Borrower shall bind its successors and assigns and shall inure
     to the benefit of Lender, its successors and assigns. Borrower shall
     not, however, have the right to assign its rights under this Agreement
     or any interest therein, without the prior written consent of Lender.

     SURVIVAL.  All warranties, representations, and covenants made by
     Borrower in this Agreement or in any certificate or other instrument
     delivered by Borrower to Lender under this Agreement shall be considered
     to have been relied upon by Lender and will survive the making of the
     Loan and delivery to Lender of the Related Documents, regardless of any
     investigation made by Lender or on Lender's behalf.

     TIME IS OF THE ESSENCE.  Time is of the essence in the performance of
     this Agreement.

     WAIVER.  Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender.
     No delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender
     of a provision of this Agreement shall not prejudice or constitute a
     waiver of Lender's right otherwise to demand strict compliance with that
     provision or any other provision of this Agreement. No prior waiver by
     Lender, nor any course of dealing between Lender and Borrower, or
     between Lender and any Grantor, shall constitute a waiver of any of
     Lender's rights or of any obligations of Borrower or of any Grantor as
     to any future transactions. Whenever the consent of Lender is required
     under this Agreement, the granting of such consent by Lender in any
     instance shall not constitute continuing consent in subsequent instances
     where such consent is required, and in all cases such consent may be
     granted or withheld in the solve discretion of Lender.

    request of Lender, Grantor will deliver to Lender any and all of the
    documents evidencing or constituting the Collateral, and Grantor will
    note Lender's interest upon any and all chattel paper if not delivered to
    Lender for possession by Lender. Grantor hereby appoints Lender as its

    necessary to perfect or to continue the security interest granted in this
    Agreement. Lender may at any time, and without further

                                   (CONTINUED)
===============================================================================
    authorization from Grantor, file a carbon, photographic or other
    reproduction of any financing statement or of this Agreement for use as a
    financing statement. Grantor will reimburse Lender for all expenses for
    the perfection and the continuation of the perfection of Lender's
    security interest in the Collateral. Grantor promptly will notify Lender
    before any change in Grantor's name including any change to the assumed
    business names of Grantor. THIS IS A CONTINUING SECURITY AGREEMENT AND
    WILL CONTINUE IN EFFECT EVEN THOUGH ALL OR ANY PART OF THE INDEBTEDNESS
    IS PAID IN FULL AND EVEN THOUGH FOR A PERIOD OF TIME GRANTOR MAY NOT BE
    INDEBTED TO LENDER.

    NO VIOLATION. The execution and delivery of this Agreement will not
    violate any law or agreement governing Grantor or to which Grantor is a
    party, and its certificate or articles of incorporation and bylaws do not
    prohibit any term or condition of this Agreement.

    ENFORCEABILITY OF COLLATERAL. To the extent of Collateral consists of
    accounts, chattel paper, or general intangibles, the Collateral is
    enforceable in accordance with its terms, is genuine, and complies with
    applicable laws concerning form, content and manner of preparation and
    execution, and all persons appearing to be obligated on the Collateral
    have authority and capacity to contract and are in fact obligated as they
    appear to be on the Collateral. At the time any account becomes subject
    to a security interest in favor of Lender, the account shall be a good and
    valid account representing an undisputed, bona fide indebtedness incurred
    by the account debtor, for merchandise held subject to delivery
    instructions or theretofore shipped or delivered pursuant to a contract of
    sale, or for services theretofore performed by Grantor with or for the
    account debtor; there shall be no setoffs or counterclaims against any
    such account; and no agreement under which any deductions or discounts
    may be claimed shall have been made with the account debtor except those
    disclosed to Lender in writing.

    REMOVAL OF COLLATERAL. Grantor shall keep the Collateral (or to the
    extent the Collateral consists of intangible property such as accounts,
    the records concerning the Collateral) at Grantor's address shown above,
    or at such other locations as are acceptable to Lender. Except in the
    ordinary course of its business, including the sales of inventory,
    Grantor shall not remove the Collateral from its existing locations
    without the prior written consent of Lender. To the extent that the
    Collateral consists of vehicles, or other titled property, Grantor shall
    not take or permit any action which would require application for
    certificates of title for the vehicles outside the State of Florida,
    without the prior written consent of Lender.

    TRANSACTIONS INVOLVING COLLATERAL. Except for inventory sold or accounts
    collected in the ordinary course of Grantor's business, Grantor shall not
    sell, offer to sell, or otherwise transfer or dispose of the Collateral.
    Grantor shall not pledge, mortgage, encumber or otherwise permit the
    Collateral to be subject to any lien, security interest, encumbrance, or
    charge, other than the security interest provided for in this Agreement,
    without the prior written consent of Lender. This includes security
    interests even if junior in right to the security interests granted under
    this Agreement. Unless waived by Lender, all proceeds form any
    disposition of the Collateral (for whatever reason) shall be held in
    trust for Lender and shall not be commingled with any other funds;
    provided however, this requirement shall not constitute consent by Lender
    to any sale or other disposition. Upon receipt, Grantor shall immediately
    deliver any such proceeds to Lender.

    TITLE. Grantor represents and warrants to Lender that it holds good and
    marketable title to the Collateral, free and clear of all liens and
    encumbrances except for the lien of this Agreement. No financing
    statement covering any of the Collateral is on file in any public office
    other than those which reflect the security interest created by this
    Agreement or to which Lender has specifically consented. Grantor shall
    defend Lender's rights in the Collateral against the claims and demands
    of all other persons.

    COLLATERAL SCHEDULES AND LOCATIONS. As often as Lender shall require, and
    insofar as the Collateral consists of accounts, Grantor shall deliver to
    Lender schedules of such Collateral, including such information as Lender
    may require, including without limitation names and addresses of account
    debtors and agings of accounts. Such information shall be submitted for
    Grantor and each of its subsidiaries or related companies.

    MAINTENANCE AND INSPECTION OF COLLATERAL. Grantor shall maintain all
    tangible Collateral in good condition and repair. Grantor will not commit
    or permit damage to or destruction of the Collateral or any part of the
    Collateral. Lender and its designated representatives and agents shall
    have the right at all reasonable times to examine, inspect, and audit the
    Collateral wherever located. Grantor shall immediately notify Lender of
    all cases involving the return, rejection, repossession, loss or damage
    of or to any Collateral; of any request for credit or adjustment or of
    any other dispute arising with respect to the Collateral; and generally
    of all happenings and events affecting the Collateral or the value or the
    amount of the Collateral.

    TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes,
    assessments and liens upon the Collateral, its use or operation, upon
    this Agreement, upon any promissory note or notes evidencing the
    indebtedness, or upon any of the other Related Documents. Grantor may
    withhold any such payment or may elect to contest any lien if Grantor is
    in good faith conducting an appropriate proceeding to contest the
    obligation to pay and so long as Lender's interest in the Collateral is
    not jeopardized in Lender's sole opinion. If the Collateral is subjected
    to a lien which is not discharged within fifteen (15) days, Grantor shall
    deposit with Lender cash, a sufficient corporate surety bond or other
    security satisfactory to Lender in an amount adequate to provide for the
    discharge of the lien plus any interest, costs or other charges that
    could accrue as a result of foreclosure or sale of the Collateral. In any
    contest Grantor shall defend itself and Lender and shall satisfy any
    final adverse judgment before enforcement against the Collateral. Grantor
    shall name Lender as an additional obligee under any surety bond
    furnished in the contest proceedings.

    COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall comply promptly
    with all laws, ordinances, rules and regulations of all governmental
    authorities, now or hereafter in effect, applicable to the ownership,
    production, disposition, or use of the Collateral. Grantor may contest in
    good faith any such law, ordinance or regulation or withhold compliance
    during any proceeding, including appropriate appeals, so long as Lender's
    interest in the Collateral, in Lender's opinion, is not jeopardized.

    HAZARDOUS SUBSTANCES. Grantor represents and warrants that the Collateral
    never has been, and never will be so long as this Agreement remains a
    lien on the Collateral, used for the generation, manufacture, storage,
    transportation, treatment, disposal, release or threatened release or any
    hazardous waste or substance, as those terms are defined in the
    Comprehensive Environmental Response, Compensation, and Liability Act of
    1980, as amended, 42 U.S.C. Section 9601, et seq. ("CERCLA"), the
    Superfund Amendments and Reauthorization Act of 1986, Pub. L. No. 99-499
    ("SARA"), the Hazardous Materials Transportation Act, 49 U.S.C. Section
    1801, et seq., the Resource Conservation and Recovery Act, 42 U.S.C.
    Section 6901, et seq., or other applicable state or Federal laws, rules,
    or regulations adopted pursuant to any of the foregoing. The terms
    "hazardous waste" and "hazardous substance" shall also include, without
    limitation, petroleum and petroleum by-products or any fraction thereof
    and asbestos. The representations and warranties contained herein are
    based on Grantor's due diligence in investigating the Collateral for
    hazardous wastes and substances. Grantor hereby (a) releases and waives
    any future claims against Lender for indemnity or contribution in the
    event Grantor becomes liable for cleanup or other costs under any such
    laws, and (b) agrees to indemnify and hold harmless Lender against any
    and all claims and losses resulting from a breach of this provision of
    this Agreement. This obligation to indemnify shall survive the payment of
    the indebtedness and the satisfaction of this Agreement.

    MAINTENANCE OF CASUALTY INSURANCE. Grantor shall procure and maintain all
    risks insurance, including without limitation fire, theft and liability
    coverage together with such other insurance as Lender may require with
    respect to the Collateral, in form, amounts, coverages and basis
    reasonably acceptable to Lender and issued by a company or companies
    reasonably acceptable to Lender. Grantor, upon request of Lender, will
    deliver to Lender from time to time the policies or certificates of
    insurance in form satisfactory to Lender, including stipulations that
    coverages will not be cancelled or diminished without at least thirty
    (30) days' prior written notice to Lender and not including any
    disclaimer of the insurer's liability for failure to give such a notice.
    Each insurance policy also shall include an endorsement providing that
    coverage in favor of Lender will not be impaired in any way by any act,
    omission or default of Grantor or any other person. In connection with
    all policies covering assets in

                                (Continued)
------------------------------------------------------------------------------
------------------------------------------------------------------------------
     which Lender holds or is offered a security interest, Grantor will
     provide Lender with such loss payable or other endorsements as Lender
     may require. If Grantor at any time fails to obtain or maintain any
     insurance as required under this Agreement, Lender may (but shall not be
     obligated to) obtain such insurance as Lender deems appropriate,
     including if it so chooses "single interest insurance," which will cover
     only Lender's interest in the Collateral.

     APPLICATION OF INSURANCE PROCEEDS. Grantor shall promptly notify Lender
     of any loss or damage to the Collateral. Lender may make proof of loss
     if Grantor fails to do so within fifteen (15) days of the casualty. All
     proceeds of any insurance on the Collateral, including accrued proceeds
     thereon, shall be held by Lender as part of the Collateral. If Lender
     consents to repair or replacement of the damaged or destroyed
     Collateral, Lender shall, upon satisfactory proof of expenditure, pay or
     reimburse Grantor from the proceeds for the reasonable cost of repair or
     restoration. If Lender does not consent to repair or replacement of the
     Collateral, Lender shall retain a sufficient amount of the proceeds to
     pay all of the indebtedness, and shall pay the balance to Grantor. Any
     proceeds which have not been disbursed within six (6) months after their
     receipt and which Grantor has not committed to the repair or restoration
     of the Collateral shall be used to prepay the indebtedness.

     INSURANCE RESERVES. Lender may require Grantor to maintain with Lender
     reserves for payment of insurance premiums, which reserves shall be
     created by monthly payments from Grantor of a sum estimated by Lender to
     be sufficient to produce, at least fifteen (15) days before the premium
     due date, amounts at least equal to the insurance premiums to be paid.
     If fifteen (15) days before payment is due, the reserve funds are
     insufficient, Grantor shall upon demand pay any deficiency to Lender.
     The reserve funds shall be held by Lender as a general deposit and shall
     constitute a non-interest-bearing account which Lender may satisfy by
     payment of the insurance premiums required to be paid by Grantor as they
     become due. Lender does not hold the reserve funds in trust by Grantor,
     and Lender is not the agent of Grantor for payment of the insurance
     premiums required to be paid by Grantor. The responsibility for the
     payment of premiums shall remain Grantor's sole responsibility.

     INSURANCE REPORTS. Grantor, upon request of Lender, shall furnish to
     lender reports on each existing policy of insurance showing such
     information as Lender may reasonably request including the following:
     (a) the name of the insurer; (b) the risks insured; (c) the amount of
     the policy; (d) the property insured; (e) the then current value on the
     basis of which insurance has been obtained and the manner of determining
     that value; and (f) the expiration date of the policy. In addition,
     Grantor shall upon request by Lender (however not more often than
     annually) have an independent appraiser satisfactory to Lender
     determine, as applicable, the cash value or replacement cost of the
     Collateral.

GRANTOR'S RIGHT TO POSSESSION AND TO COLLECT ACCOUNTS. Until default and
except as otherwise provided below with respect to accounts, Grantor may have
possession of the tangible personal property and beneficial use of all the
Collateral and may use it in any lawful manner not inconsistent with this
Agreement or the Related Documents, provided that Grantor's right to
possession and beneficial use shall not apply to any Collateral where
possession of the Collateral by Lender is required by law to perfect Lender's
security interest in such Collateral. Until otherwise notified by Lender,
Grantor may collect any of the Collateral consisting of accounts. At any time
and even though no Event of Default exists, Lender may exercise its rights to
collect the accounts and to notify account debtors to make payments directly
to Lender for application to the Indebtedness. If Lender at any time has
possession of any Collateral, whether before or after an Event of Default,
Lender shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral if Lender takes such action for that purpose
as Grantor shall request or as Lender, in Lender's sole discretion, shall
deem appropriate under the circumstances, but failure to honor any request by
Grantor shall not of itself be deemed to be a failure to exercise reasonable
care. Lender shall not be required to take any steps necessary to preserve
any rights in the Collateral against prior parties, nor to protect, preserve
or maintain any security interest given to secure the Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without
limitation all taxes, liens, security interests, encumbrances, and other
claims, at any time levied or placed on the Colateral. Lender also may (but
shall not be obligated to) pay all costs for insuring, maintaining and
preserving the Collateral. All such expenditures incurred or paid by Lender
for such purposes will then bear interest at the rate charged under the Note
from the date incurred or paid by Lender to the date of repayment by Grantor.
All such expenses shall become a part of the indebtedness and, at lender's
option, will (a) be payable on demand, (b) be added to the balance of the
Note and be apportioned among and be payable with any installment payments to
become due during either (i) the term of any applicable insurance policy or
(ii) the remaining term of the Note, or (c) be treated as a balloon payment
which will be due and payable at the Note's maturity. This Agreement also
will secure  payment of these amounts. Such right shall be in addition to all
other rights and remedies to which lender may be entitled upon the occurrence
of an Event of Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

     DEFAULT ON INDEBTEDNESS. Failure of Grantor to make any payment when due
     on the indebtedness.

     OTHER DEFAULTS. Failure of Grantor to comply with or to perform any
     other term, obligation, covenant or condition contained in this
     Agreement or in any of the Related Documents or in any other agreement
     between Lender and Grantor.

     FALSE STATEMENTS. Any warranty, representation or statement made or
     furnished to Lender by or on behalf of Grantor under this Agreement, the
     Note or the Related documents is false or misleading in any material
     respect, either now or at the time made or furnished.

     DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related
     Documents ceases to be in full force and effect (including failure of
     any collateral documents to create a valid and perfected security
     interest or lien) at any time and for any reason.

     INSOLVENCY. The dissolution or termination of Grantor's existence as a
     going business, the insolvency of Grantor, the appointment of a receiver
     for any part of Grantor's property, any assignment for the benefit of
     creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy or insolvency laws by or against Grantor.

     CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help
     repossession or any other method, by any credit or Grantor or by any
     governmental agency against the Collateral or any other collateral
     securing the Indebtedness. This includes a garnishment of any of
     Grantor's deposit accounts with Lender.

     EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with
     respect to any Guarantor of any of the indebtedness or such Guarantor
     dies or becomes incompetent.

     ADVERSE CHANGE. A material adverse change occurs in Grantor's financial
     condition, or Lender believes the prospect of payment or performance of
     the Indebtedness is impaired.

     INSECURITY. Lender, in good faith, deems itself insecure.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a
secured party under the Florida Uniform Commercial Code. In addition and
without limitation, Lender may exercise any one or more of the following
rights and remedies:

     ACCELERATE INDEBTEDNESS. Lender may declare the entire indebtedness,
     including any prepayment penalty which Grantor would be required to pay,
     immediately due and payable, without notice.

     ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender all
     or any portion of the Collateral and any and all certificates of title
     and other documents relating to the Collateral. Lender may require
     Grantor to assemble the Collateral and make it available to Lender at a
     place to be s\designated by Lender. Lender also shall have full power to
     either upon the property of Grantor to take possession of and remove the

                                 (Continued)
------------------------------------------------------------------------------
------------------------------------------------------------------------------
     Collateral. If the Collateral contains other goods not covered by this
     Agreement at the time of repossession, Grantor agrees Lender may take
     such other goods, provided that Lender makes reasonable efforts to
     return them to Grantor after repossession.

     SELL THE COLLATERAL. Lender shall have full power to sell, lease,
     transfer, or otherwise deal with the Collateral or proceeds thereof in
     its own name or that of Grantor. Lender may sell the Collateral at
     public auction or private sale. Unless the Collateral threatens to
     decline speedily in value or is of a type customarily sold on a
     recognized market, Lender will give Grantor reasonable notice of the
     time after which any private sale or any other intended disposition of
     the Collateral is to be made. The requirements of reasonable notice
     shall be met if such notice is given at least ten (10) days before the
     time of the sale or disposition. All expenses relating to the
     disposition of the Collateral, including without limitation the expenses
     of retaking, holding, insuring, preparing for sale and selling the
     Collateral, shall become a part of the indebtedness secured by this
     Agreement and shall be payable on demand, with interest at the Note rate
     from date of expenditure until repaid.

     APPOINT RECEIVER. To the extent permitted by applicable law, Lender shall
     have the following rights and remedies regarding the appointment of a
     receiver: (a) Lender may have a receiver appointed as a matter of right,
     (b) the receiver may be an employee of Lender and may serve without bond,
     and (c) all fees of the receiver shall become part of the indebtedness
     secured by this Agreement and shall be payable on demand, with interest
     at the Note rate from date of expenditure until repaid.

     COLLECT REVENUES, APPLY ACCOUNTS. Lender, either itself or through a
     receiver, may collect the payments, rents, income, and revenues from the
     Collateral. Lender may at any time in its discretion transfer any
     Collateral into its own name or that of its nominee and receive the
     payments, rents, income, and revenues therefrom and hold the same as
     security for the indebtedness or apply it to payment of the indebtedness
     in such order of preference as Lender may determine. Insofar as the
     Collateral consists of accounts, general intangibles, insurance
     policies, instruments, chattel paper, choses in action, or similar
     property, Lender may demand, collect, receipt for, settle, compromise,
     adjust, sue for, foreclose, or realize on the Collateral as Lender may
     determine, whether or not indebtedness or Collateral is then due. For
     these purposes, Lender may, on behalf of and in the name of Grantor,
     receive, open and dispose of mail addressed to Grantor; change any
     address to which mail and payments are to be sent; and endorse notes,
     checks, drafts, money orders, documents of title, instruments and items
     pertaining to payment, shipment, or storage of any Collateral. To
     facilitate collection, Lender may notify account debtors and obligors on
     any Collateral to make payments directly to Lender.

     OBTAIN DEFICIENCY. If Lender chooses to sell any or all of the
     Collateral, Lender may obtain a judgment against Grantor for any
     deficiency remaining on the indebtedness due to Lender after application
     of all amounts received from the exercise of the rights provided in this
     Agreement. Grantor shall be liable for a deficiency even if the
     transaction described in this subsection is a sale of accounts or chattel
     paper.

     OTHER RIGHTS AND REMEDIES. Lender shall have all the rights and remedies
     of a secured creditor under the provisions of the Uniform Commercial
     Code, as may be amended from time to time. In addition, Lender shall
     have and may exercise any or all other rights and remedies it may have
     available at law, in equity, or otherwise.

     CUMULATIVE REMEDIES. All of Lender's rights and remedies, whether
     evidenced by this Agreement or the Related Documents or by any other
     writing, shall be cumulative and may be exercised singularly or
     concurrently. Election by Lender to pursue any remedy shall not exclude
     pursuit of any other remedy, and an election to make expenditures or to
     take action to perform an obligation of Grantor under this Agreement,
     after Grantor's failure to perform, shall not affect Lender's right to
     declare a default and to exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are  a part
of this Agreement:

     AMENDMENTS. This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to
     the matters set forth in this Agreement. No alteration of or amendment
     to this Agreement shall be effective unless given in writing and signed
     by the party or parties sought to be charged or bound by the alteration
     or amendment.

     APPLICABLE LAW. This Agreement has been delivered to Lender and accepted
     by Lender in the State of Florida. If there is a lawsuit, Grantor agrees
     upon Lender's request to submit to the jurisdiction of the courts of the
     State of Florida. This Agreement shall be governed by and construed in
     accordance with the laws of the State of Florida.

     CAPTION HEADINGS. Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the
     provisions of this Agreement.

     NOTICES. All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimile (unless otherwise
     required by law), and shall be effective when actually delivered or when
     deposited with a nationally recognized overnight courier or deposited in
     the United States mail, first class, postage prepaid, addressed to the
     party to whom the notice is to be given at the address shown above. Any
     party may change its address for notices under this Agreement by giving
     formal written notice to the other parties, specifying that the purpose
     of the notice is to change the party's address. To the extent permitted
     by applicable law, if there is more than one Grantor, notice to any
     Grantor will constitute notice to all Grantors. For notice purposes,
     Grantor will keep Lender informed at all times of Grantor's current
     address(es).

     POWER OF ATTORNEY. Grantor hereby appoints Lender as its true and lawful
     attorney-in-fact, irrevocably, with full power of substitution to do the
     following: (a) to demand, collect, receive, receipt for, sue and recover
     all sums of money or other property which may now or hereafter become
     due, owing or payable from the Collateral; (b) to execute, sign and
     endorse any and all claims, instruments, receipts, checks, drafts or
     warrants issued in payment for the Collateral; (c) to settle or
     compromise any and all claims arising under the Collateral, and, in the
     place and stead of Grantor, to execute and deliver its release and
     settlement for the claim; and (d) to file any claim or claims or to take
     any action or institute or take part in any proceedings, either in its
     own name or in the name of Grantor, or otherwise, which in the
     discretion of Lender may seem to be necessary or advisable. This power
     is given as security for the indebtedness, and the authority hereby
     conferred is and shall be irrevocable and shall remain in full force and
     effect until renounced by Lender.

     SEVERABILITY. If a court of competent jurisdiction finds any provision
     of this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances. If feasible,
     any such offending provision shall be deemed to be modified to be within
     the limits of enforceability or validity; however, if the offending
     provision cannot be so modified, it shall be stricken and all other
     provisions of this Agreement in all other respects shall remain valid and
     enforceable.

     SUCCESSOR INTERESTS. Subject to the limitations set forth above on
     transfer of the Collateral, this Agreement shall be binding upon and
     inure to the benefit of the parties, their successors and assigns.

     WAIVER. Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender. No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right. A waiver by Lender
     of a provision of this Agreement shall not prejudice or constitute a
     waiver of Lender's right otherwise to demand strict compliance with that
     provision or any other provision of this Agreement. No prior waiver by
     Lender, nor any course of dealing between Lender and Grantor, shall
     constitute a waiver of any of Lender's rights or of any of Grantor's
     obligations as to any future transactions. Whenever the consent of Lender
     is required under this Agreement, the granting of such consent by Lender
     in any instance shall not constitute continuing consent to subsequent
     instances where such consent is required and in all cases such consent
     may be granted or withheld in the sole discretion of Lender.

ARBITRATION. Any claim or controversy ("Claim") between the parties, whether
arising in contract or tort or by statute including, but not limited to,
Claims resulting from or relating to this Agreement shall, upon the request
of either party, be resolved by arbitration in accordance with the Federal

Arbitration Act (Title 9, US Code). Arbitration proceedings will be conducted
in accordance with the rules for arbitration of financial services disputes
of J.A.M.S./Endispute. The arbitration shall be conducted in any state where
real or personal property collateral for the credit is located or if there is
no collateral, in the state of any Borrower's domicile at the time of the
execution of this Agreement or at the commencement of any arbitration
proceeding. The arbitration hearing shall commence within 90 days of the
demand for arbitration and close within 90 days of commencement, and any
award, which may include legal fees, shall be issued (with a brief written
statement of the reasons therefore) within 30 days of the close of hearing.
Any dispute concerning whether a claim is arbitrable or barred by the statute
of limitations shall be determined by the arbitrator. This arbitration
provision is not intended to limit the right of any party to exercise
self-help remedies, to seek and obtain interim or provisional relief of any
kind or to initiate judicial or non-judicial foreclosure against any real or
personal property collateral.

adverse effect upon the financial condition of Borrower.

(3) Borrower will promptly notify Lender in the event Borrower determines
that any computer application which is material to the operations of
Borrower, its subsidiaries or any of its material vendors or suppliers will
not be fully Year 2000 compliant on a timely basis, except to the extent that

upon the financial condition of Borrower.

COMPLIANCE WITH LOAN DOCUMENTS. Borrower(s) acknowledge(s) and agree(s) that
(its) (their) timely and complete compliance with all of the terms and
conditions contained in the documents evidencing and securing the loan
obligation is material consideration for the loan. Borrower('s)(s') failure
to timely and completely comply with each and every term and condition
contained in the documents evidencing and securing the loan is, at Lender's
option, an event of default under the loan. In addition to all other rights
and remedies Lender has, Lender may, in its sole discretion, elect to waive
such default or to forbear to exercise its rights and remedies for such
default and may charge Borrower(s) a fee for agreeing to do so.

FINANCIAL STATEMENT. Borrower(s) acknowledge(s) and agree(s) that Lender's
ability to monitor and evaluate the status of the loan is dependent upon
Borrower(s) timely providing financial information required herein. In
addition to all other rights and remedies Lender has should Borrower(s) fail
to timely provide the financial information, including declaring the loan to
be in default, Lender may charge Borrower(s) a late fee up to 10 basis points
(.1%) of the outstanding principal balance or committed loan amount,
whichever is greater, not to be less than $500.00. The charging and/or payment
of the fee is not a waiver of the Borrower('s)(s') continuing obligation to
provide the required financial information.

                           TAX INDEMNITY AGREEMENT

     This Agreement is made the 24th day of September, 1999, by Regeneration
Technologies, Inc. ("Borrower"), and Bank of America, N.A., ("Lender").

     WHEREAS, Bank is making, renewing, substituting, consolidating or
modifying a $6,000,000.00 loan dated September 24, 1999 ("Loan"), executed by
Borrower, upon which State of Florida documentary stamp tax and/or
non-recurring intangible taxes (jointly and severally, the "taxes") may or
may not be due, same dependent upon the structure of the Loan; and

     WHEREAS Borrower is of the opinion that the Loan may not be subject to
the Taxes and has requested that Lender not collect, withhold nor pay the
Taxes; and

     WHEREAS Borrower has been informed by Lender that non-payment of the
Taxes may create a potential liability to Lender in the event that any claims
are brought against Lender by reason of non-payment of the Taxes;

     NOW THEREFORE Lender has requested, and Borrower has agreed to give,
this Agreement with the Borrower indemnifying the Lender as follows:

     1.  Borrower assumes the risk of all damage, loss, cost and expense
(including interest and penalties, if any), and agrees to indemnify and hold
harmless Lender, its directors, officers, agents and employees from and
against any and all liability, damage, loss, cost, expense, or reasonable
attorney fees which may accrue to or be sustained by Lender, its directors,
officers, agents or employees on account of or arising from any claim or
action raised by, filed or brought by or in the name of any State of Florida
Governmental or Administrative Department with respect to non-payment of the
Taxes against Lender, its directors, officers, agents or employees in
connection with the Loan.

     2.  Borrower agrees to pay Lender against any claim brought or action
filed against Bank with respect to the subject of this indemnity contained
herein, whether such claim or action is rightfully or wrongfully brought or
filed.

     3.  Bank shall use its best efforts to give written notice to Borrower
of any claim or action which Lender is to be indemnified against herein in a
timely manner after written notice of such claim or action is received by
Lender, by sending notification via certified or registered mail, postage
prepaid, return receipt requested or overnight courier to Borrower at its
billing address shown on Lender's billing system. Lender shall also request
from the entity making said demand or inquiry that the demand or inquiry be
in writing and sent to Lender, but is not responsible for non-compliance with
its request. Additionally, Borrower shall give immediate notice to Lender if
Borrower receives any notice of any possible or actual claim or action.

     4.  In case a claim should be brought or action filed with respect to
the subject of indemnity herein, Borrower agrees that Lender may employ
attorneys of its own selection to appear and defend the claim or action on
behalf of Lender, at the expense of Borrower. Lender, at its option, shall
have authority for the direction of the defense, and shall be the judge of
the acceptability of any compromise or settlement or any claims or actions
against Lender; however, Borrower has right to be advised of any compromises
or settlements and upon request to the Lender, to be joined in the lawsuit as
a party Defendant, therefore allowing the Borrower to assert its own defenses.



<PAGE>


     5.  Indemnities and obligations provided herein shall continue in full
force and effect notwithstanding the expiration or termination of the Loan
for any reason whatsoever. Nothing in this Agreement or otherwise shall
authorize any of the parties hereto or any other person or entity to act so
as to incur or impose any liability or obligation for or on behalf of the
others.

     6.  It is further understood and agreed by the parties hereto that if
any of the provisions hereof shall contravene, or be invalid under the laws
of the State of Florida, or any county or jurisdiction where used, such
contravention or invalidity shall not invalidate this Agreement but shall be
construed as if not containing the particular provision or provisions held to
be invalid, and the rights or the obligations of the parties hereto shall be
construed and enforced accordingly.

     7.  Each party agrees to execute and deliver, or cause to be executed
and delivered, all such instruments, certificates and documents, and to take
all such other actions as the other party to this Agreement may reasonably
request from time to time to effectuate the purpose and intent of this
Agreement.

     8.  The failure of Lender to insist in any one or more instances upon
performance of any of the provisions of this Agreement or to take advantage
of its rights hereunder shall not be construed as a waiver of any such
provisions or the relinquishment of such rights, and the same shall continue
and remain in full force and effect. No single or partial exercise by Lender
of any right or remedy shall preclude other or further exercise thereof or
the exercise of any other right or remedy. Waiver by Lender of any branch of
any provision of this Agreement shall not constitute or be construed as a
continuing waiver or as a waiver of any other breach of any other provision
of this Agreement.

     9.  This Agreement contains the entire agreement between the parties
with respect to the matters contemplated herein and supersedes and cancels
all prior agreements between them whether oral, written or implied. No
modifications, amendments or waivers of this Agreement, or any of its
provisions, shall be binding on any party unless evidenced by a written
instrument duly executed by the parties.

     The undersigned have executed this Indemnity Agreement on the day and
year first appearing.
