			     RESEARCH PROJECT

     CryoLife will provide Biocompatibles with the following
tissues to which Biocompatibles will supply the Biocompatibles
Technology and assess such Technology's ability to generate the
outcome described below.

Project Scope and Defined Outcomes

A.  Tissues

      The scope of this research project involves multiple
tissues which Cryolife will provide for coating according to the
Biocompatibles Technology.

	 1.  Porcine Heart Valves

	       a.  Cellular, glutaraldehyde-fixed

		   (1)   aortic (including leaflets and aortic
			 conduit)

		   (2)   pulmonary (including leaflets and
			 pulmonary artery)

	       b.  Acellular, unfixed or glutaraldehyde-fixed

		     (1) aortic

		     (2) pulmonary

	 2.  Porcine (or other xenogenic) Circulatory Vessels

	       a.  Acellular vein

	       b.  Acellular artery

	 3.  Bovine Ligamentous Grafts

	       a.  Ligament

	       b.  Tendon

	       c.  Fascia Lata

	 4.  Other Xenogenic Tissues

	       a.  Dura mater

	       b.  Pericardium

	       c.  Nerves

	 5.    Cryopreserved Human Allograft Tissues including,
	       but not limited to, Heart Valves, Vessels and
	       Nerves 

B.  Defined Outcomes

      A selection of coated tissues as defined in A. (v.s.) will
be assessed according to the following tests to demonstrate the   
effectiveness of Biocompatibles Technology coatings in providing
the indicated results.  These tests will be applied according to
the particular requirements for each coated tissue.

	   1.  Coverage - Surface covering of the coated tissues
	       is anticipated.  Coverage of the tissue will be
	       demonstrated to be uniform and unbroken.

	   2.  The tissue surface coatings is expected to remain
	       intact and unbroken for an agreed clinically
	       relevant time period; no thinning of the coating
	       is expected.  Coating stability will be assessed
	       following exposure of the coated tissues in:  1)
	       static cultures in the presence of tissue culture
	       media, blood, or similar medium; 2) in dynamic
	       (stirred) cultures of similar medium; and 3) in
	       orthotopic or heterotopic in vivo implants of the
	       coated tissues.  As in B.1., coating coverage will
	       be demonstrated.

	   3.  Histology and ultrastructure - the matrix protein
	       structure of the coated tissue should appear
	       normal by light and transmission electron
	       microscopic analyses.

	   4.  Nonthrombogenicity/Noninflammatory - limited and 
	       nonprogressive platelet and/or white cell adhesion
	       in at lest one of the following models:  1)
	       subdernial implant in rat (inflammation); b) in
	       vitro platelet and/or white cell adhesion; c)
	       intravascular or intrasynovial implant in vivo. 

	    5.  Biomechanical characteristics

		  a.     Extensibility - should not change more
			 than 10% relative to a selected standard
			 tissue.

		  b.     Stress-relaxation - relaxation slope and 
			 ultimate relaxation should reflect
			 retention of viscoelastic properties
			 with no more than a 10% change in
			 relaxation slope or ultimate relaxation
			 relative to standard fixed tissue.  

		  c.     Load at Failure and Maximum Stress at
			 Failure - should not change more than
			 10% relative to a selected standard
			 tissue.

	    6.  Toxicity/Biocompatibility

		  a.     The coating material should be
			 compatible with cell survival and cell
			 proliferation and function.

		  b.     The coated tissue should be compatible
			 with cell survival and cell
			 proliferation and function (either non-
			 fixed tissues or tissues fixed with
			 other than glutaraldehyde).

		  c.     Cytocompatibility of coated tissues will
			 be assessed by supplementing cell
			 culture media with aqueous extracts made
			 from tissues following coating and
			 observing the effect of such
			 supplementation on the growth rates of
			 fibroblast and endothelial cells.

		  d.     Nontoxicity or cytocompatibility will be 
			 defined as growth rates of cells in the
			 presence of coating-related materials
			 being within 10% of the growth rates of
			 cells grown under control conditions.

	    7.  Anticalcification

	       A model of implanting treated tissues subdermally
	       in weanling rats will be used to assess effects of
	       coating(s)on the rate and extent of tissue
	       calcification.  At least a 60% reduction in the
	       extent of calcification relative to uncoated
	       control tissue is considered acceptable after 16
	       weeks of implantation.

C.  Acceptance Parameters

      1.  Coatings will be screened according to the tests
	  outline in B.(v.s.). 

      2.  Up to seven coating formulations will be screened for   
	  each tissue type.

      3.  Coatings will be selected based on disclosure of known  
	  properties to CryoLife.

      4.  Tests will be selected according to suitability for
	  each tissue type.

      5.  Parameters:

	  a.   coverage - see B.1.

	  b.   stability - B.2.

	  c.   histology and ultrastructure - see B.3.  Various   
	       standard stains will be applied to sectioned
	       tissues to facilitate observation of collagens,
	       elastin, glycosaminoglycans, and glycoproteins. 
	       Comparisons with untreated tissues will be carried
	       out by a qualified pathologist.  Transmission
	       electron microscopy will be used to examine, among
	       other factors, collagen periodicity, collagen
	       fiber crimp, and so on. 

	 d.    nonthrombogenicity/noninflammatory - see B.4.

	 e.    biomechanical characteristics - see B.5.

	 f.    toxicity/biocompatibility - see B.6.

	 g.    anticalcification - see B.7.  We anticipate the    
	       acceptable levels of coated tissue calcium will be
	       no greater than 5 mg/g dry weight of tissue after
	       16 weeks of implantation.

D.  Schedules

      1.  Preliminary Screening of Coatings 
	  Initial examinations of coatings will entail analysis
	  of: 1) coating thickness and consistency; 2) cellular
	  and extracellular matrix morphology, 3) appropriate
	  biomechanical parameters; 4) biocompatibility of
	  coating and of treated tissue; and 5) effect of coating
	  on rate and extent of calcification of the coated
	  tissue.  It is anticipated that only those coating with
	  acceptable outcomes for coating properties and tissue
	  morphology (D.1.1. and D.1.2.) will be delivered to
	  CryoLife for further analysis.

      2.  Secondary Screening Outcomes 

     As indicated, those coating displaying acceptable outcomes
in  the Preliminary Screenings (D.1.) will be further analyzed by 
in vivo implants to demonstrate: 1) thrombogenicity/inflammatory
response characteristics, and 2) stability of the coating in a
functional graft model.

formulae, and processes for applying Biocompatibles' proprietary
and patent protected "coating polymers" to preserved animal and
human tissues;
      
    WHEREAS, CryoLife desires to license the Biocompatibles
Technology (defined below). 

    NOW, THEREFORE, for good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, and in
consideration of the mutual covenants set forth below, the
parties agree as follows:

    1.    Definitions.  Capitalized terms not otherwise defined
herein shall have the meanings given to them in the Research
Agreement when used in this Agreement.

    "Biocompatibles Technology" shall mean the secret and
proprietary information, data, formulae, methods, processes,
products and techniques of Biocompatibles or its affiliates for
coating materials with polymers which improve the
biocompatibility of implantable devices.  The Biocompatibles
Technology includes information, data, formulae, methods,
processes, products and techniques developed by Biocompatibles
during or after the course of conducting any Research Project
pursuant to the Research Agreement.  Biocompatibles Technology
includes the Know-How, Patents and Trade Secrets.

Agreement and (ii) treated with the Biocompatibles Technology.
The parties shall endeavor to maintain a record of Processed
Tissues by amending Schedule B attached hereto to include all
tissue groups notified for inclusion as and when Biocompatibles
receives proper notification.

    "Trade Secrets" shall mean any and all Confidential
Information heretofore or hereafter owned, developed, acquired or
licensed by Biocompatibles, relating to the Biocompatibles
Technology.

    2.    License.

	  (a)  License Grant.  Biocompatibles hereby grants
CryoLife a license to the Biocompatibles Technology to develop,
manufacture, use, and distribute Processed Tissues throughout the
world.  The license is exclusive in the United States and is the
sole license Biocompatibles will grant outside the United States;
provided, however, that Biocompatibles agrees  not to produce or
coat porcine heart valves with the Biocompatibles Technology
during the Initial Five Year Term (defined in Section 6(a)),
except to the extent Biocompatibles participates in a joint
venture or partnership with CryoLife for coating valves in the
United States.

	  (b)  Sublicense.  CryoLife shall have the right to
grant sublicenses of any rights granted to it under this license,
provided that CryoLife shall have received the prior written
approval of Biocompatibles, which shall not be unreasonably
withheld.

    3.    Payments by CryoLife.

	  (a)  Non-Royalty Payments.  CryoLife shall pay
Biocompatibles the sums identified in subsections (d) through and
including (h) of Section 3.1 of the Research Agreement upon
completion of the conditions set forth in those provisions.

	  (b)  Percentage Royalties.  CryoLife shall pay
Biocompatibles a royalty on Net Revenues (gross revenues minus
sales taxes, reasonable discounts, freight and returns, if any)
from all distribution of Processed Tissues by CryoLife.  The
amount of the royalty payable for Processed Tissues distributed
in countries ("Protected Countries") where the Processed Tissues
are protected by a patent or patent application at the time of
distribution shall be 10% of  Net Revenues. The royalty payable
for Processed Tissues distributed outside of Protected Countries
shall be 5% of Net Revenues generated outside of Protected
Countries.

	  (c)  Minimum Royalties.  CryoLife shall pay
Biocompatibles minimum royalties commencing on the first day of
the first calendar quarter following first  commercial
distribution of Processed Tissues after approval for unrestricted
commercial sale by the European Union or the U.S. Food and Drug
Administration as follows:

	       Year 1                        $100,000
	       Year 2                        $150,000
	       Year 3                        $200,000
	       Year 4                        $300,000
	       Year 5 and thereafter         $400,000  

Minimum royalties will be payable in equal quarterly installments
and shall be credited toward earned royalties due under
Subsections (b) and (c) above. The obligation to pay minimum
royalties shall expire upon the expiration of patent protection
for the Technology in the United States or Europe.  Failure to
make royalty payments equal to or exceeding minimum royalty
obligations in any year shall be deemed a breach or default under
this Agreement and may result in its termination by
Biocompatibles. 

	  (d)  Reports; Audit Rights.  Payments of royalties
under Section 3(b) shall be made on a monthly basis and shall be
payable within 20 days following the end of the preceding month. 
Such payment shall be accompanied by a statement showing
distribution of the Processed Tissues by CryoLife to all parties,
and such other particulars as are necessary or which may be
reasonably requested by Biocompatibles in order to verify
accurate payment of royalties and fees pursuant to this
Section 3.  CryoLife shall keep complete and accurate records of
all distributions by CryoLife of the Processed Tissues and all
sublicenses granted hereunder.  Biocompatibles and its
representatives shall have the right during the term of this
Agreement and for a period of two years following any termination
of this Agreement to review the books and records of CryoLife
relating to distribution of the Processed Tissues and sublicenses
granted hereunder in order to verify payments under this
Agreement.  All costs of such audit shall be borne by
Biocompatibles; provided, however, in the event such audit
reveals an underpayment of more than 5%, CryoLife shall
immediately pay the amount of the underpayment and shall
reimburse Biocompatibles for the costs incurred in connection
with the audit.

	  (e)  Pricing of Processed Tissues.  In the event
CryoLife sells the Processed Tissues for use with other products
of CryoLife (a "Combined Product"), the purchase price for the
Combined Product shall be reasonably allocated between the
Processed Tissues and CryoLife's other products.  In the event
Biocompatibles objects to such allocation, the matter shall be
submitted to arbitration in accordance with Section 7(i).

    4.    Representations of Biocompatibles; Patents.

	  (a)  Title.  Biocompatibles hereby represents and
warrants that it owns all right, title, and interest in and to
the Biocompatibles Technology which is germane to the granting of
the license contained in this Agreement and is authorized to
enter into and perform its obligations under this Agreement. 
Biocompatibles represents and warrants that Schedule B attached
hereto lists all of the patents and patent applications relating
to the Biocompatibles Technology.  Biocompatibles has not granted
any other licenses to the Biocompatibles Technology for use with
Processed Tissue.  

	  (b)  Patents.  CryoLife agrees to cooperate with
Biocompatibles at Biocompatibles cost in the preparation, filing,
and prosecution of  domestic and foreign Patent(s) applications
and to keep each other fully informed at all times of the status
of the  Patent(s) and applications.

	  (c)  Prosecution of Patents.  Biocompatibles shall have
the sole right in the first instance to take appropriate
measures, including the bringing or defending of suits throughout
the world, to prevent or stop infringement or misappropriation by
others in making, using or selling Processed Tissues.  CryoLife
may participate in such suit through counsel of its own choosing,
and in its own name.  All costs of any infringement, declaratory
judgment or other suit brought or defended by Biocompatibles
shall be the obligation of Biocompatibles.  In the event of
recovery of damages in, or sums and settlement of, a suit or
suits for infringement or misappropriation brought or defended by
Biocompatibles, Biocompatibles shall be entitled to retain
two-thirds of whatever recovery (after costs) of sums for damages
or otherwise that might be obtained in such suit or settlement,
with one-third of the recovery (after costs) being payable to
CryoLife.  CryoLife agrees to cooperate with Biocompatibles to
prevent or stop such infringement or misappropriation and to
provide Biocompatibles with documents, data, and other
information as may be reasonably necessary to conduct such suit
by Biocompatibles.  When such disclosures are identified as
Confidential Information, then Biocompatibles undertakes to
ensure that the confidentiality of those disclosures is
maintained.  Should Biocompatibles fail or refuse to take or
cause to be taking any such measures against any third party
after one month from the date of receipt of written notice to
Biocompatibles by CryoLife of such infringement or
misappropriation accompanied by reasonable evidence of such
infringement or misappropriation, CryoLife may take such legal
action in its own name and at its own expense.  In such latter
case, CryoLife shall be entitled to retain two-thirds of whatever
recovery (after costs) of sums for damages or otherwise that it
may obtain in such suit or settlement, with one-third of the
recovery (after costs) being payable to Biocompatibles.  When
either party litigates under this paragraph, it shall keep the
other party informed of such activities in writing at least every
calendar quarter.

    5.    Indemnification.  Biocompatibles shall defend,
indemnify, and hold CryoLife and its officers, directors,
employees and affiliates harmless from and against any and all
damages, liabilities, losses, and expenses (collectively,
"Damages"), including reasonable attorneys fees and court costs,
incurred by CryoLife as a result of any claim, lawsuit, action,
or proceeding (collectively, "Claim") against CryoLife in which
it is determined or alleged that the Biocompatibles Technology
infringes on any trade secret, patent, copyright, or other
proprietary right of any third party.  Except as provided above,
CryoLife shall indemnify, defend, and hold Biocompatibles and its
officers, directors, employees and affiliates harmless from and
against any and all Damages incurred by Biocompatibles arising
out of any Claim of a third party based upon the production,
distribution, or marketing by CryoLife of the Processed Tissues. 
Any party claiming indemnification pursuant to this Section 5
(the "Indemnitee") shall give prompt notice of any claim,
lawsuit, action or proceeding with respect to which
indemnification is claimed and shall cooperate fully, at the cost
of the indemnifying party, in the defense or settlement thereof. 
The indemnifying party shall have sole control of the defense,
negotiation, or settlement of any matter with respect to which
indemnification is claimed.

    6.    Termination.

	  (a)  Term.  This license shall continue in full force
and effect for each Processed Tissue for a term ending five years
after receipt of regulatory approval in the United States or
European Union to commercialize the Processed Tissue (the

additional one year terms thereafter so long as CryoLife is not
in material default hereunder for a period of up to ten years or
the life of any Patents, whichever is longer.  This Agreement may
be earlier terminated by CryoLife by giving 90 days advance
written notice.

	  (b)  Breach by CryoLife.  In the event CryoLife commits
any breach of the material terms and conditions of this

option to terminate this Agreement.

	  (d)  Survival.  The provisions of Sections 3(e), 5,
this Section 6(d) and 7 shall survive any termination of this
Agreement.  Termination of this Agreement shall not affect or
terminate CryoLife's obligation to pay any amounts which were
payable pursuant to the terms of Section 3 with respect to sales
of Processed Tissues and grants of sublicenses prior to the
effective date of such termination.
