of the Net Sales of Licensed Products. In the event the last patent application
under this Agreement is abandoned and no patent in Regents' Patent Rights has
issued, Licensee shall pay to The Regents an earned royalty of [ *** ] in the
first full year of commercial sales of Licensed Products covered by Regent's
Proprietary Rights following such abandonment, [ *** ] in the second full year
of such commercial sales following such abandonment, [ *** ] in the third full
year of such commercial sales following such abandonment, [ *** ] in the fourth
year of such commercial sales following such abandonment, and no earned royalty
in subsequent years.

        5.2 For sales of Licensed Products to an Affiliate or Joint Venture
from Licensee at a reduced price from that customarily charged to an unrelated
third party, the royalty paid to The Regents shall be based on the Net Sales of
Licensed Products of the Affiliate or Joint Venture to the Affiliate's or Joint
Venture's customers. Where Licensee transfers Licensed Products for end-use to
itself or an Affiliate or Joint Venture, such transfer shall be considered a
sale at list price, and The Regents shall be entitled to receive a royalty
thereon in accordance with this Article 5, (ROYALTIES). Each reference to
Licensee herein shall be meant to include its Affiliates and Joint Ventures.

        5.3 Paragraphs 1.1, 1.2, 1.3, and 1.4 define Regents' Patent Rights,
Licensed Products, and Licensed Methods so that royalties shall be payable on
products and methods covered by both pending patent applications and issued
patents as well as on products and methods covered by Regents' Proprietary
Rights. Earned royalties shall accrue in each country for the 

***Confidential treatment requested

                                       6
<PAGE>   28
duration of Regents' Patent Rights in that country and shall be payable to The
Regents when Licensed Products are invoiced, or if not invoiced, when delivered
to a third party. In the event the last patent application under this Agreement
in that country is abandoned and no patent in Regents' Patent Rights has issued
for that country then Licensee shall pay to The Regents an earned royalty based
on sales of Licensed Products covered by The Regents' Proprietary Rights in
that country as provided in paragraph 5.1.

        5.4     Royalties accruing to The Regents shall be paid to The Regents 
[ *** ] on or before the following dates [ *** ]:

                                    [ *** ]

                                    [ *** ]

                                    [ *** ]

                                    [ *** ]

Each such payment will be for royalties which accrued within the Licensee's
most recently completed [ *** ].

        5.5     Licensee shall pay to The Regents a minimum annual royalty of 
[ *** ] and [ *** ] thereafter, beginning with the calendar year [ *** ]. This
minimum annual royalty shall be paid to The Regents by [ *** ] of each year and 
shall be credited against the earned royalty (if any) due and owing for the 
calendar year in which the minimum payment was made.

        5.6     Notwithstanding the minimum royalties stated in paragraph 5.5
(Minimum Royalties), in the event the last patent application under this
Agreement is abandoned and no patent in Regents' Patent Rights has issued,
Licensee shall pay to The Regents a minimum annual royalty

*** confidential treatment requested

                                       7

<PAGE>   29
equal to [ *** ] of the minimum royalty stipulated for that year in paragraph
5.5 for the first year of commercial sales following such abandonment, [ *** ]
of the minimum royalty stipulated for that year in paragraph 5.5 for the second
full year of such commercial sales following such abandonment, [ *** ] of the
minimum royalty stipulated for that year in paragraph 5.5 for the third full
year of such commercial sales following such abandonment, [ *** ] of the
minimum royalty stipulated for that year in paragraph 5.5 for the fourth year of
such commercial sales following such abandonment, and no minimum annual royalty
in subsequent years.

        5.7     All monies due The Regents shall be payable in United States
funds collectible at par in San Francisco, California. When Licensed Products
are sold for monies other than United States dollars, the earned royalties will
first be determined in the foreign currency of the country in which such
Licensed Products were sold and then converted into equivalent United States
funds. The exchange rate will be that rate quoted in the Wall Street Journal on
the last business day of the reporting period.

        5.8     Royalties earned with respect to sales occurring in any country
outside the United States shall not be reduced by any taxes, fees, or other
charges imposed by the government of such country on the remittance of royalty
income. The Licensee shall also be responsible for all bank transfer charges.
Notwithstanding this, all payments made by the Licensee in fulfillment of The
Regents' tax liability in any particular country shall be credited against
Earned Royalties, royalties, or fees due The Regents for that country.

        5.9     If at any time legal restrictions prevent the prompt remittance
of part or all royalties by the Licensee with respect to any country where a
Licensed Product is sold, the

*** confidential treatment requested


                                       8
<PAGE>   30
Licensee shall pay such royalties to The Regents from the Licensee's United
States source of funds.

        5.10 In the event that any patent or any claim thereof included within
the Regents' Patent Rights shall be held invalid in a final decision by a court
of competent jurisdiction and last resort and from which no appeal has or can
be taken, all obligation to pay royalties based on such patent or claim or any
claim patentably indistinct therefrom shall cease as of the date of such final
decision. The Licensee shall not, however, be relieved from paying any
royalties that accrued before such decision or that are based on another patent
or claim not involved in such decision or that are based on the Regents'
Proprietary Rights.

                                6. DUE DILIGENCE

        6.1 The Licensee, upon execution of this Agreement, shall diligently
proceed with the development, manufacture, and sale of Licensed Products and
shall earnestly and diligently endeavor to market the same within a reasonable
time after execution of this Agreement and in quantities sufficient to meet the
market demands therefor.

        6.2 The Licensee shall be entitled to exercise prudent and reasonable
business judgment in meeting its due diligence obligations hereunder.

        6.3 The Licensee shall endeavor to obtain all necessary governmental
approvals for the manufacture, use, and sale of Licensed Products.

        6.4 If the Licensee is unable to perform any of the following:

        6.4.1 initiate a pilot animal study for the device by [ *** ]; or

        6.4.2 complete the pilot animal study for the device and, if it is

              by December 31, 1994; or

        6.4.3 submit a 510K covering Licensed Products to the United States FDA
              by [ *** ]; or  

        6.4.4 initiate human trials on the device and complete the full animal
              study on the device by [ *** ]; or

        6.4.5 market Licensed Products in the United States within [ *** ] of
              receiving approval of such Licensed Product's 510K or PMA from
              the U.S. FDA; or 

        6.4.6 reasonably fill the market demand for Licensed Products following
              commencement of marketing at any time during the exclusive period
              of this Agreement; 

then The Regents shall have the right and option either to terminate this
Agreement or to reduce the Licensee's exclusive license to a nonexclusive
license. This right, if exercised by The Regents, supersedes the rights granted
in Article 2 (GRANT).

        6.5 In addition to the obligations set forth above, the Licensee shall
spend an aggregate of not less than [ *** ] for the development and
commercialization of Licensed Products during the first 3 years of this
Agreement according to the following schedule:

        6.6     Either party to this Agreement may refer a dispute arising
under this Article 6 (DUE DILIGENCE) to arbitration. Such referral to
arbitration shall be made by so notifying the other party in writing in
accordance with the provisions of Article 19 hereto (NOTICES), stating the
nature of the dispute to be resolved. Any such arbitration shall be controlled
by the provisions of this Article 6.

        6.7     Within fifteen (15) business days following such notice, three
arbitrators shall be selected by the following process:

        6.7.1   Each Party shall designate one individual, not an employee,
                director, or shareholder of the Party or sublicensee of the
                Party, to serve as an arbitrator.

        6.7.2   These arbitrators shall select a third individual who shall be
                an attorney experienced in arbitration proceedings to serve as
                the third arbitrator and to preside in resolution of the
                dispute. The third arbitrator shall not be an employee,
                director, or shareholder of either Party or sublicensee of
                either Party.

        6.8     Within five (5) business days after selection, the arbitrators
shall meet with the Parties at which time the Parties shall each present in
writing the issue to be resolved and a proposed ruling on it. Such writing
shall be served on the other Party in advance and shall be limited to no more
than twenty (20) pages.

        6.9     The following general provisions shall apply to the
arbitration proceeding:

        6.9.1   No later than thirty (30) days after the appointment of the
third arbitrator, the arbitrators shall set a date for a hearing to resolve the
issue identified by the Parties.  The hearing shall take place no later than
one hundred twenty (120)


                                       11

        days from the original notice to arbitrate.

6.9.2   The arbitrators shall permit the taking of no more than one (1)
        deposition by each Party, and shall permit, subject to the provisions of
        a mutually agreeable protective order, the production of only those
        documents immediately and directly bearing on the issue or issues
        subject to arbitration and only to the extent necessary for the
        convenience and use of the arbitrators, and shall not require or permit
        any other discovery by any means, including, but not limited to,
        depositions, interrogatories, or production of documents.


6.9.3   No later than ten (10) business days prior to the hearing, each Party
        may submit a single written brief or memorandum in support of its
        position which may be no more than twenty (20) pages. Each Party shall
        be entitled to no more than three (3) hours of hearing to present
        testimony or documentary evidence. Such time limitation shall include
        any direct, cross, or rebuttal testimony, but such time limitation shall
        only be charged against the Party conducting such direct, cross, or
        rebuttal testimony. It shall be the responsibility of the arbitrators to
        determine whether each Party has had the three (3) hours to which it is
        entitled or may, upon good cause shown, have additional time to present
        its case.

6.9.4   Each Party shall have the right to be represented by counsel. The
        arbitrators shall have sole discretion with regard to the admissability
        of evidence. Admissibility will be decided by two-thirds vote.

Party must submit a proposed finding to the arbitrators.

        6.10 The arbitrators shall rule on the disputed issue within thirty
(30) days following the completion of the testimony of both Parties. Such
ruling shall encompass in its entirety the proposed findings of one of the
Parties on the disputed issue. The issue shall be resolved upon two-thirds vote
of the arbitrators.

        6.11 Arbitration shall take place in the location of choice of the
party who has not requested arbitration. All hearing costs for a hearing shall
be shared equally between the Parties.

        6.12 The arbitrators shall be paid reasonable fees plus expenses, which
fees and expenses shall be shared equally by the Parties.

        6.13 The decision of the arbitrators shall be enforceable but not
appealable in any court of competent jurisdiction.

        6.14 To exercise either the right to terminate this Agreement or to
reduce the license to a nonexclusive license for lack of diligence, The Regents
must give the Licensee written notice of the deficiency. The Licensee
thereafter has sixty (60) days to cure the deficiency or to request
arbitration. If The Regents has not received a written request for arbitration
or satisfactory tangible evidence that the deficiency has been cured by the end
of the sixty (60)-day period, then The Regents may, at its option, either
terminate this Agreement or reduce the Licensee's exclusive license to a
nonexclusive license by giving written notice to the Licensee. These notices
shall be subject to Article 19 (NOTICES).

The Regents a progress report covering the Licensee's activities related to the

Affiliates.

        7.4     The Licensee also agrees to report to The Regents in its
immediately subsequent progress and royalty report the date of first commercial
sale of a Licensed Product in each country.

the number of each type of Licensed Product sold, (c) the royalties, in U.S.
dollars, payable hereunder with respect to such sales, (d) the method used to
calculate the royalty, and (e) the exchange rates used.

        7.6  If no sales of Licensed Products have been made during any
reporting period, a statement to this effect shall be required.


                             8.  BOOKS AND RECORDS

        8.1  The Licensee shall keep books and records accurately showing all
Licensed Products manufactured, used, and/or sold under the terms of this
Agreement. Such books and records shall be preserved for at least five (5)
years from the date of the royalty payment to which they pertain and shall be
open to inspection by representatives or agents of The Regents at reasonable
times.

        8.2  The fees and expenses of The Regents' representatives performing
such an examination shall be borne by The Regents. However, if an error in
royalties of more than five percent (5%) of the total royalties due for any
year is discovered, then the fees and expenses of these representatives shall
be borne by the Licensee.

parties in accordance with the terms of this Agreement, this Agreement shall be
in force from the effective date recited on page one and shall remain in effect
for the life of the last-to-expire patent licensed under this Agreement, or for
twenty (20) years from the effective date of this Agreement if no patent

        10.1  If the Licensee should violate or fail to perform any term or
covenant of this Agreement, then The Regents may give written notice of such
default (Notice of Default) to the Licensee. If the Licensee should fail to
repair such default within sixty (60) days of the effective date of such
notice, The Regents shall have the right to terminate this Agreement and the
licenses herein by a second written notice (Notice of Termination) to the
Licensee. If a Notice of


                                       16

<PAGE>   38
Termination is sent to the Licensee, this Agreement shall automatically
terminate on the effective date of such notice. Such termination shall not
relieve the Licensee of its obligation to pay any royalty or license fees owing
at the time of such termination and shall not impair any accrued right of The
Regents. These notices shall be subject to Article 19 (Notices).

                          11.  TERMINATION BY LICENSEE

        11.1    The Licensee shall have the right at any time to terminate this

relieve the Licensee of any obligation of liability accrued hereunder prior to
such termination or rescind anything done by the Licensee or any payments made
to The Regents hereunder prior to the time such termination becomes effective,
and such termination shall not affect in any manner any rights of The Regents
arising under this Agreement prior to such termination. Any unpaid part of the
License Issue Fee of paragraph 4.1 becomes due and payable at the time of
termination by Licensee.

         12.  DISPOSITION OF LICENSED PRODUCTS ON HAND UPON TERMINATION

        12.1    Upon termination of this Agreement, the Licensee shall have the
privilege of disposing of all previously made or partially made Licensed

provided, however, that the sale of such Licensed Products 


                                       17
<PAGE>   39
shall be subject to the terms of this Agreement including, but not limited to,

conferring any right to use in advertising, publicity, or other promotional
activities any name, trade name, trademark, or other designation of either
party hereto (including contraction, abbreviation, or simulation of any of the
foregoing). Unless required by law, the use by the Licensee of the name "The

        13.3    Notwithstanding paragraph 13.2, it is understood that The 
Regents shall be free to release to the inventors and senior administrative 
officials employed by The Regents the terms and conditions of this Agreement
upon their request. If such release is made, The Regents shall request that
such terms and conditions not be disclosed to others. It is further understood
that should a third party inquire whether a license to Regents' Patent Rights
is available, The Regents may disclose the existence of this Agreement and the

                             14.  LIMITED WARRANTY

                 patents are dominant or subordinate to Regent's Patent Rights; 
                 or

        (14.4.5) an obligation to furnish any know-how not provided in Regents'

                     15. PATENT PROSECUTION AND MAINTENANCE

        15.1 Provided that Licensee has paid billings and rebillings as
provided for in paragraph 15.4, The Regents shall diligently prosecute and
maintain the United States patents comprising Regents' Patent Rights using
counsel of its choice. The Regents' counsel will take instructions only from
The Regents. The Regents shall provide the Licensee with copies of all relevant
documentation so that the Licensee may be informed and apprised of the
continuing prosecution. The Licensee agrees to keep this documentation
confidential. 

        15.2 The Regents shall use all reasonable efforts to amend any patent
application to include claims reasonably requested by the Licensee to protect
the products contemplated to be sold under this Agreement.

Such prior costs (approximately $8,611.71 as of September 30, 1993) will be due
within thirty (30) days of the execution of this Agreement. Current and future
costs for patent prosecution and maintenance will be billed to the Licensee by
The Regents as incurred and shall be payable within thirty (30) days of the
billing date.

        15.5 The Licensee shall have the right to request The Regents to obtain
patent protection on the Invention in foreign countries if available and if it
so desires. The Licensee must notify The Regents within seven (7) months of the
filing of the corresponding United States application of its decision to obtain
foreign patents. This notice concerning foreign filing shall be in writing,
must identify the countries desired, and reaffirm Licensee's obligation to
underwrite the costs thereof. The absence of such a notice from the Licensee to
The Regents shall be considered an election not to secure foreign rights.

        15.6 The preparation, filing, and prosecuting of all foreign patent
applications filed at the Licensee's request, as well as the maintenance of all
resulting patents, shall be at the sole expense of the Licensee. Such patents
shall be held in the name of the Regents and shall be obtained using counsel of
The Regents' choice.

<PAGE>   43
        15.7 The Licensee's obligation to underwrite and to pay patent
prosecution costs shall continue for so long as this Agreement remains in
effect provided, however, that the Licensee may terminate its obligations with
respect to any given patent application or patent upon three (3) months written
notice to The Regents. The Regents will use its best efforts to curtail patent
costs when such a notice is received from the Licensee. Those costs which
cannot be curtailed will be due and owing when rebilled. The Regents may
continue prosecution and/or maintenance of such application(s) or patent(s) at
its sole discretion and expense provided, however, that the Licensee shall have
no further right or licenses thereunder.

        15.8 The Regents shall have the right to file, prosecute, or maintain 
patent applications at its own expense in any country in which the Licensee has
not elected to file, prosecute, or maintain patent rights in accordance with
this Article 15, and such applications and resultant patents shall not be
subject to this Agreement.

                               16. PATENT MARKING

        16.1 The Licensee agrees to mark all Licensed Products made, used, or
sold under the terms of this Agreement, or their containers, in accordance with
the applicable patent marking laws.

                            17. PATENT INFRINGEMENT

        17.1 In the event that the Licensee shall learn of the substantial
infringement of any patent or patent extension licensed under this Agreement,
the Licensee shall call The Regents' attention thereto in writing and shall
provide The Regents with reasonable evidence of such

                                       22
 
<PAGE>   44
infringement. Both parties to this Agreement agree that during the period and
in a jurisdiction where the Licensee has exclusive rights under this Agreement,
neither will notify a third party of the infringement of any of Regents' Patent
Rights without first obtaining consent of the other party, which consent shall
not be unreasonably denied. Both parties shall use their best efforts in
cooperation with each other to terminate such infringement without litigation.

        17.2 The Licensee may request that The Regents take legal action
against the infringement of Regents' Patent Rights. Such request shall be made
in writing and shall include reasonable evidence of such infringement and
damages to the Licensee. If the infringing activity has not been abated within
ninety (90) days following the effective date of such request, The Regents
shall have the right to:

             a) commence suit on its own account or

             b) refuse to participate in such suit,

and The Regents shall give notice of its election in writing to the Licensee by
the end of the one-hundredth (100th) day after receiving notice of such request
from the Licensee. The Licensee may thereafter bring suit for patent
infringement if and only if The Regents elects not to commence suit and if the
infringement occurred during the period and in a jurisdiction where the
Licensee had exclusive rights under this Agreement. However, in the event the
Licensee elects to bring suit in accordance with this paragraph, The Regents
may thereafter join such suit at its own expense.

        17.3 Such legal action as is decided upon shall be at the expense of
the party on account of whom suit is brought and all recoveries recovered
thereby shall belong to such party provided, however, that legal action brought
jointly by The Regents and the Licensee and fully

                                       23
<PAGE>   45
participated in by both shall be at the joint expense of the parties and all
recoveries shall be shared jointly by them in proportion to the share of
expense paid by each party.

        17.4    Each party agrees to cooperate with the other in litigation
proceedings instituted hereunder but at the expense of the party on account of
whom suit is brought. Such litigation shall be controlled by the party bringing
the suit except that The Regents may be represented by counsel of its choice
pursuant to The Regents' determination in any suit brought by the Licensee.

                              18.  INDEMNIFICATION

        18.1    The Licensee agrees to indemnify, hold harmless, and defend The
Regents, their officers, employees, and agents; the sponsors of the research
that led to the Invention; and the inventors of the patents and patent
applications in Regents' Patent Rights and their employers against any and all
claims, suits, losses, damage, costs, fees, and expenses resulting from or
arising out of exercise of this license or any sublicense. This indemnification
will include, but will not be limited to, any product liability.

        18.2    The Licensee, at its sole cost and expense, shall insure its
activities in connection with the work under this Agreement, and before
Licensee conducts any non-financial commercialization activities concerning the
Licensed Products outside of development and trials performed at the University
of California by employees of the University of California, Licensee  shall
obtain, keep in force, and maintain Comprehensive or Commercial Form General
Liability Insurance (contractual liability included) or an equivalent program
of self-insurance with limits as follows:

evidencing compliance with all requirements. Such certificates shall:

                (18.2.1)        Provide a thirty (30)-day advance written
                                notice to the University of any modification.

                (18.2.2)        Indicate that The Regents has been endorsed as
                                an additional insured under the coverages 
                                referred to under the above.

                (18.2.3)        Include a provision that the coverages will be
                                primary and will not participate with nor will
                                be excess over any valid and collectible
                                insurance or program of self-insurance carried
                                or maintained by The Regents.

        18.3    The Regents shall promptly notify Licensee in writing of
any claim or suit brought against The Regents in respect of which The Regents
intends to invoke the provisions of this Article 18. Licensee will keep The
Regents informed on a current basis of its defense of any claims pursuant to
this Article 18.

         2.2. Acceptance of Obligations; Best Efforts. The Distributor hereby
accepts the appointment described in Section 2.1 and hereby agrees to use its
best efforts at all times during the term hereof to register, promote, market,
sell and distribute the Agreement Product and any Improved Agreement Product(s)
in the Territory. [ *** ]

         2.3. Conversion to Non-Exclusive Distributorship. In the event that (i)
in any Agreement Year after and including the third Agreement Year or (ii) from,
after and including the first year of the Distributor acquiring and/or

force majeure condition of the Distributor exists at such time pursuant to
Section 20, (ii) Biomatrix has met its supply obligations under Section 7.4 and
(iii) Distributor is able to lawfully sell the Agreement Product and any
Improved Agreement product(s) in each of the countries within any such Region)

non-exclusive distribution arrangement in any Region, Biomatrix shall have the
right to distribute the Agreement Product and Improved Agreement Product and/or
engage another distributor for such Region. Biomatrix will give Distributor [
*** ] days notice prior to appointing a third party distributor for such Region.
From and after the date of a conversion to a non-exclusive distribution
arrangement within a Region, the Distributor shall lose its rights hereunder to
register, promote, market, sell and distribute within such Region any Improved
Agreement Product(s) commercialized on or after such date. Notwithstanding the
foregoing, the Distributor shall retain the exclusive rights in all trademarks
under which the Distributor launched the Agreement Product or any Improved
Agreement Product(s) in such Region. Upon conversion of Distributor's rights to
a non-exclusive distribution arrangement in any Region in the European
Territory, the arrangements between the parties under this Agreement shall no
longer be governed by this Agreement and such Region shall no longer be deemed a
part of the Territory, but rather, such Region shall become the subject of a new
agreement between the parties upon the same terms and conditions set forth in
this Agreement. Upon such conversion to a non-exclusive arrangement, the parties
agree to execute such further documents and agreements as are necessary in order
to give effect to the provisions of this Section.

         2.4. Expansion of Territory. One or more countries may be added to the
Territory from time to time after the Effective Date by mutual written agreement
of the parties hereto, conditional upon the satisfactory completion of the
necessary due diligence in such country and the satisfaction of Biomatrix with
the proposed arrangements for the registration, promotion, marketing, sale and
distribution of the Agreement Product and any Improved Agreement Product(s) by
the Distributor in such country. Biomatrix agrees to discuss the appointment of
Distributor or one of its subdistributors prior to appointing a third party
distributor of the Agreement Product in any additional country.

         3. TERM AND TERMINATION.

         3.1. Effective Date. This Agreement shall take effect as of the
Effective Date.

         3.2. Term.

         (a) Unless this Agreement is sooner terminated, in its entirety or as
to a country or Region in the Territory in accordance with the provisions of
this Agreement, the term of the appointment hereunder for a country in the
Territory shall commence on the first day of the first Agreement Year for such
country and shall end on the last day of the tenth (10th) Agreement Year for
such country (the "Initial Term").

         (b) Unless this Agreement is sooner terminated, in its entirety or as
to any Region in the Territory in accordance with the provisions of this
Agreement, the appointment of the Distributor hereunder as exclusive distributor
of the Agreement Product for each Region in the Territory shall be renewable by
the Distributor, at its option, upon written notice to Biomatrix received at
least ninety (90) days prior to the end of the Initial Term for such Region, for
an additional consecutive term of five (5) years following the date of
expiration of the Initial Term for such Region, provided that the Distributor
shall only be entitled to exercise such renewal option with respect to any
Region if as of the date of expiration of the Initial Term for such Region the
Distributor is not in material breach of any of its obligations under this
Agreement with respect to any Region (it being understood that any payment
default by Distributor under this Agreement will be deemed a default as to the
entire Territory). Thereafter, the appointment of the Distributor as exclusive
distributor of the Agreement Product for such Region shall be renewable upon the
expiration of such additional five (5) year term, upon written notice to
Biomatrix received at least ninety (90) days prior to the end of such term for
such Region, for one additional consecutive renewal term of five (5) years,
provided that, as of the date of expiration of the first renewal term for such
Region, the Distributor is not in material breach of any of its obligations
under this Agreement with respect to any Region (it being understood that any
payment default by Distributor under this Agreement will be deemed a default as
to the entire Territory). For the avoidance of any doubt, the Distributor's
rights with respect to any Improved Agreement Product(s) commercialized after
the tenth anniversary of the Effective Date shall terminate upon the tenth
anniversary of the Effective Date. Subject to the terms of this Agreement,
Distributor shall have the right to continue to sell the Agreement Product and
any Improved Agreement Products it is then currently selling.

         (c) This Agreement may be terminated with respect to any country in the
Territory by either party, by written notice to the other party, in the event
that (i) a mutual decision not to Launch the Agreement Product in such country
is reached or (ii) a Launch is not commenced with respect to such country within
thirty (30) days after the time period set forth on Exhibit B.

         (d) In the event that in any Agreement Year commencing with the third
Agreement Year (and so long as (i) no force majeure condition of the Distributor
exists at such time pursuant to Section 20, (ii) Biomatrix has met its supply
obligations under Section 7.4, and (iii) Distributor is able to lawfully sell
the Agreement product and any Improved Agreement Product(s) in each of the
countries within any such Region), the Distributor's (and its Affiliates' or
Subdistributors', as applicable) Net Retail Sales of the Agreement Product and
any Improved Agreement Product(s) in any Region comprise less than seven and
one-half percent (7-1/2%) of its Net Retail Sales in such Region of all Dermal
Tissue Augmentation Products, including the Agreement Product and any Improved
Agreement Product(s), the Distributor's distribution rights (including, without
limitation, its right to use the Trademarks) under this Agreement for the
Agreement Product and any Improved Agreement Product(s) in such Region shall
terminate upon 90 days notice, but in any event no later than 120 days after the
end of the applicable Agreement Year, to Distributor from Biomatrix; provided,
however, that Distributor may within thirty (30) days after receipt of any such
notice from Biomatrix, cure a shortfall of Net Retail Sales with respect to a
Region in the Territory, other than Regions in the European Territory, Australia
and Canada, for an Agreement Year by paying to Biomatrix an amount equal to
twenty-five percent (25%) of the total dollar amount of any such shortfall of
Net Retail Sales in such Agreement Year for such Region (such amount the "Cure
Amount"); further provided that with respect to any Region in the Territory, at
Biomatrix's election, Biomatrix may refuse to allow such cure if Distributor has
taken advantage of such cure provision with respect to such Region in each of
the two preceding Agreement Years.

                                      -10-


By way of example, if Distributor's Net Retail Sales of all Dermal Tissue
Augmentation Products in a Region in a given Agreement Year [$10,000,] and
Distributor's Net Retail Sales of the Agreement Product in such Region in such
Agreement Year were $500, then Distributor could cure such shortfall and prevent
termination by paying Biomatrix $62.50. Distributor may cure a shortfall of Net
Retail Sales with respect to Regions in the European Territory, Australia or
Canada in an Agreement Year by paying the Cure Amount to Biomatrix with respect
to any such Region for such Agreement Year as provided above; provided, however,
that in exchange for such Cure Amount Biomatrix will supply Distributor with an
amount of units of the Agreement Product purchasable for such Cure Amount at the
applicable Minimum Price or Formula Price for the applicable Agreement Year for
such Region; further provided that with respect to any such Region, at
Biomatrix's election, Biomatrix may refuse to allow such cure if Distributor has
taken advantage of such cure provision w/respect to such Region in each of the
two preceding Agreement Years. Upon any such termination of the Distributor's
distribution rights in a Region, the Distributor's obligation to pay any
royalties pursuant to Sections 8.1 and 8.2 for any sales in such Region after
such termination shall cease, but the Distributor shall remain obligated to pay
all such royalties for sales in such Region accrued prior to such termination.

         (e) If the Distributor's rights to distribute the Agreement Product and
any Improved Agreement Product(s) in any country in the European Territory shall
terminate solely pursuant to subsection (d) above, Biomatrix agrees to sell the
Agreement Product and any Improved Agreement Product(s) developed before the
date of such termination to the Distributor a price not greater than the price
paid by another distributor appointed in such country in the European territory,
for the period of time equal to the period that would have remained in the
Initial Term in such country had the Distributor's distribution rights not
terminated.

         3.3. Inventory.

         (a) Upon termination of this Agreement for any reason, Biomatrix shall
have the right (but not the obligation) to repurchase all or part of the
inventory of the Agreement Product and any Improved Agreement Product(s) held by
the Distributor or its Affiliates or Subdistributors.

         (b) The price for inventory to be repurchased by Biomatrix pursuant to
Section 3.3(a) above shall be the landed cost thereof actually paid by the
Distributor to Biomatrix. With respect to any quantities not repurchased by
Biomatrix, the Distributor shall have the

<PAGE>   11
                                      -11-


right to sell such inventory of the Agreement Product and any Improved Agreement
Product(s), in its usual and customary manner, in the ordinary course of
business, for a period of six (6) months following termination of this Agreement
and notwithstanding such termination the terms and conditions of this Agreement
shall apply to such sales.

         3.4. Insolvency. This Agreement may be immediately terminated as to the
entire Territory by either party, upon giving written notice to the other party,
in the event that the other party shall become insolvent or be declared bankrupt
by a court of competent jurisdiction or shall be the subject of any
reorganization (other than a corporate reorganization effected in the ordinary
course of business and not arising out of any insolvency) or winding up,
receivership or dissolution, bankruptcy or liquidation proceeding, or any
proceeding or action similar to one or more of the above, in which case
termination shall be effective upon such written notice. The failure of either
party to give notice of termination upon obtaining knowledge of any such event
shall not be interpreted as a waiver of such party's rights under this Section
3.4, and such party reserves the right to exercise any such rights at any time
after the occurrence of any such event.

         3.5. Breach. This Agreement may be terminated as to the entire
Territory by either party if the other party shall breach any of its payment
obligations hereunder or with respect to any Region if Distributor (or its
Affiliates or Subdistributors, as applicable) shall commit a material breach of
any of its warranties, covenants, conditions, obligations or agreements
contained herein with respect to such Region, provided that such breach shall
continue for a period of thirty (30) days after written notice thereof and
provided further that such termination shall be immediately effective upon
further written notice to that effect to the breaching party after its failure
to cure such breach within such applicable notice period. For avoidance of
doubt, the parties agree that if a Launch is not reached with respect to a
country within thirty days after the time period set forth on Exhibit B, then
either party may terminate this Agreement with respect to such country (provided
that such failure to reach a Launch is not caused by a force majeure condition
of the Distributor or Biomatrix's failure to meet its supply obligations under
Section 7.4).

         3.6. Certain Rights Upon Termination. Upon termination of this
Agreement for any reason whatsoever, Biomatrix shall have the following rights,
or if such termination is as to a country in the Territory in accordance with
the provisions of this Agreement, Biomatrix shall have the following rights in
such country:

         (a) Biomatrix shall have the unrestricted right to review, access, use
and permit others to review, access and use, either directly or by
cross-reference or incorporation or otherwise, all information, data,
investigations, preclinical and clinical protocols, marketing information
disseminated by Distributor publicly to customers and patients and all
information required to be provided to Biomatrix by law, information relating to
laboratory, animal and human studies, and related regulatory approvals
pertaining to the Agreement Product or any Improved Agreement Product(s) (the
"Information") which are possessed or controlled by the Distributor or any of
its Affiliates or Subdistributors, or to which the Distributor or any of its
Affiliates or Subdistributors has a right to review, access or use.


<PAGE>   12
                                      -12-


The  Distributor  unconditionally agrees promptly to take any action and
to execute and deliver to Biomatrix any documents or instruments reasonably
requested by Biomatrix to permit Biomatrix to make full use of such unrestricted
right.

         (b) Further, Biomatrix shall have exclusive ownership rights to the
Trademarks and to all other product specific logos, slogans and other
intangibles used by the Distributor solely in association with the independent
sale of the Agreement Product and any Improved Agreement Product(s) (including
all registrations relating thereto) possessed or controlled by the Distributor
or any of its Affiliates or Subdistributors, and the Distributor unconditionally
agrees, subject to the provisions of Section 3.3(b), (i) immediately upon
termination to cease using the Trademarks and any such logos, slogans, and
marketing rights of Biomatrix or any imitations thereof and (ii) immediately to
execute and deliver to Biomatrix any documents or instruments reasonably
requested by Biomatrix to give full effect to the provisions of this Section
3.6; provided, however, if the Distributor maintains a license to distribute the
Agreement Product(s) in (a) two Regions, (b) one Region in the European
Territory or (c) in the United States, then Distributor shall retain the
exclusive rights in the Trademarks in the entire Territory.

         (c) In addition, the Distributor unconditionally agrees, subject to the
provisions of Section 3.3(b), that it shall, upon the request of Biomatrix,
immediately inform all relevant regulatory authorities that the Distributor (or
its Affiliate or Subdistributor) is no longer a distributor of the Agreement
Product or the Improved Agreement Product(s) and shall take all action and
execute and deliver all documents and instruments necessary in order to transfer
to the fullest extent permitted under applicable law all registrations and
Product License Approvals, or applications therefor, for the Agreement Product
or any Improved Agreement Product(s) to Biomatrix or any Person nominated by
Biomatrix.

         3.7. Effects of Termination.

         (a) Upon termination of this Agreement for any reason, the Distributor
shall immediately discontinue making any representations regarding its status as
a distributor for Biomatrix and shall immediately cease conducting any
activities with respect to the marketing, promotion, sale or distribution of the
Agreement Product and any Improved Agreement Product(s), provided, however, that
the Distributor shall be permitted to sell inventory not repurchased by
Biomatrix in accordance with Section 3.3.

         (b) Termination of this Agreement shall not affect obligations of
either party that may have accrued prior to the effective date of termination.
Subject to Clause 3.8 below, termination of this Agreement shall be in addition
to, and shall not be exclusive of or prejudicial to, any other grounds for
termination or rights or remedies at law or in equity which either party may
have on account of any default of the other party.

         3.8. Waiver. The Distributor (for itself and on behalf of its
Affiliates and Subdistributors) hereby waives, to the extent it is able to do so
under the law of 


<PAGE>   13
                                      -13-


every country in the Territory and other applicable law, any statutory rights it
may have or acquire in respect of the termination of the relationship
established hereby pursuant to the terms hereof, and agrees that the rights
available to it hereunder in the event of such termination are adequate and
reflect the agreement of the parties. The Distributor shall not have any right
to claim any indemnity for goodwill or lost profits or any damages arising from
the rightful termination of this Agreement in accordance with the terms hereof.

         4. PAYMENTS. All payments hereunder shall be made in Dollars. Payments
to Biomatrix shall be wired to an account designated by Biomatrix and the costs
of any such remittance shall be borne by the Distributor. All amounts (except
for the Minimum Price, which shall be denominated in Dollars) denominated in
another currency shall be converted to Dollars using the average month-end rates
of exchange for the relevant period as published in The Wall Street Journal (or,
if The Wall Street Journal shall no longer publish such exchange rates, as
determined by a method that is mutually agreed upon in writing by the parties).

         5. WITHHOLDING. All payments to be made by the Distributor under this
Agreement shall be made in full, free and clear of and without any deduction of
or withholding for or on account of any taxes levied in any country of the
Territory or elsewhere; provided that if the Distributor shall be required by
law to make any deduction or withholding from any payment to Biomatrix then:

         (a) the Distributor shall ensure that such deduction or withholding
does not exceed the minimum legal liability therefor; and

         (b) not later than five (5) days before each deduction or withholding
of any taxes, the Distributor shall forward to Biomatrix such documentary
evidence as may be required by Biomatrix in respect of the proposed deduction,
withholding or payment; and

         (c) prior to any deduction or withholding the parties shall attempt in
good faith to agree upon revised mutually acceptable pricing and/or payment
terms.

         6. TRADEMARKS; AGREEMENT PRODUCT MARKING; PROMOTIONAL INFORMATION.

         6.1. Trademarks. Subject to the provisions of Section 3.6, Biomatrix
hereby licenses to the Distributor the right to use, and hereby requires solely
in association with the independent sale by the Distributor of the Agreement
Product and any Improved Agreement Products the use of, the Trademarks in the
Territory during the term of this Agreement. The Distributor warrants that it
shall not use any of the Trademarks at any time outside the Territory or use any
of the Trademarks for any products other than the Agreement Product and any
Improved Agreement Product(s) within the Territory. The Distributor shall not
use a trademark or other mark (other than a Trademark) in connection with its
distribution of the Agreement Product and any Improved Agreement Products unless
and until it has been agreed upon in writing by each of the parties and become a
Trademark as defined herein. 


<PAGE>   14
                                      -14-


Biomatrix shall prosecute, maintain and defend the Trademarks throughout the
Term of this Agreement in all countries in the Territory in which the
Distributor, any of its Affiliates or any Subdistributor is selling the
Agreement Product and/or any Improved Agreement Product. The parties shall
execute a short form Trademark assignment agreement to the extent that it is
necessary to record the Trademark license under this Section 6.1 in any country
whose laws require any such registration.

         6.2. Termination of Right to Use Trademarks. Subject to the sell-out
right of Section 3.3(b) and except as otherwise provided in Section 3.6, upon
termination of this Agreement, the license to use the Trademarks in the
Territory shall terminate, and the Distributor unconditionally agrees promptly
to take all necessary action and execute and deliver to Biomatrix all necessary
documents and instruments to remove the Distributor as a registered user and/or
a recorded licensee of the Trademarks. In the event that the Distributor fails
promptly upon written request by Biomatrix to comply with any of its agreements
in the preceding sentence of this Section 6.2, the Distributor hereby
irrevocably consents to Biomatrix's taking any action necessary to give effect
to such agreements.

         6.3. Notice. Each party hereto agrees promptly to notify the other in
writing of any infringements or imitations of the Trademarks by third parties
which may come to its attention.

         6.4. Labelling and Promotional Materials; Approved Use of Product.

         (a) The Distributor shall provide Biomatrix with labelling masters,
instructions, specifications and copies of all marketing, labelling and
promotional material it intends to use relating to the Agreement Product and any
Improved Agreement Product(s). All such labelling, packaging and promotional
material shall be consistent with the relevant Product License Approvals and all
labelling and packaging materials shall be reviewed by Biomatrix and shall be
subject to its written approval prior to use, such approval not to be
unreasonably withheld. Biomatrix shall communicate its acceptance or rejection
of such labelling, packaging and any major promotional materials that include
claims or items impacting regulatory approvals within [ *** ] of its receipt
thereof and if no such communication is received by Distributor from Biomatrix

primary data and information in its possession as the other may reasonably
request regarding the results of the studies contained in such summary data
referred to above.

         6.7 Joint Coordinating Committee. Upon the execution of this Agreement,
Biomatrix and the Distributor shall establish a joint coordinating committee
(the "Committee") to review all matters relating to product labelling, product

taken in regard to such a recall, but in any event if after consultations either
party in good faith still believes that such a recall should be undertaken, the
parties shall cooperate in carrying out such recall.

         (b) Except as otherwise provided in (c) below, in the event of a recall
of the Agreement Product, Biomatrix shall correct any deficiency relating to its
manufacturing, packaging, testing, labelling, storing or handling of the
Agreement Product for which it is responsible, if applicable, and shall at its

         (c) Biomatrix shall reimburse Distributor for all direct costs and
expenses (including without limitation shipping, quality control testing and
notification costs) incurred by Distributor and its Affiliates as a result of
any recall, except where such recall (i) is the result of the failure of
Distributor or its Affiliates or Subdistributors to comply with their
obligations under this Agreement and/or (ii) was opposed by Biomatrix and proved
to be unwarranted, in which case Distributor shall reimburse Biomatrix for all
direct costs and expenses (including without limitation shipping, quality

[ *** ,] the Distributor shall pay to Biomatrix a fee in the amount of five

         7.2. Price; Adjustment; Reports; Payment.

         (a) The parties shall attempt in good faith to agree in writing, prior
to the Launch in each country, upon mutually acceptable supply pricing for the
Distributor's purchase of the Agreement Product and any Improved Agreement
Product(s), but such pricing in any event shall not be less than the greater of
(i) the Minimum Price, or (ii) the Formula Price, except as provided in
subsection (b) below. The parties shall attempt in good faith to agree in
writing upon mutually acceptable minimum pricing for the Agreement Product in
sizes other than the 1.0cc Treatment Syringe and for any Improved Agreement
Product(s). For any syringe with a fill volume of greater than one cc (1cc), the
Minimum Price shall be the amount calculated as [ *** ] plus the dollar amount
which equals [ *** ] of such product with a larger fill volume [ *** ] of the
one cc(1cc) syringe. In the event that Biomatrix's actual incremental Cost of
Goods Sold exceeds such dollar amount, the Minimum Price shall be the amount
calculated as [ *** .] Subject to the general commercial availability of
appropriate syringes for the Agreement Product, the [ *** ] for a one and
one-half (1.5)cc syringe, [ *** ] for a two (2.0)cc syringe, and [ *** ] for a
two and one-half (2.5)cc syringe.

         (b) If Biomatrix has appointed a new distributor for a country in the
Territory pursuant to Section 2.3 and the Distributor has the right to
distribute the Agreement Product and any Improved Agreement Product(s) in such
country, the supply pricing for the Distributor's purchase of the Agreement
Product and any Improved Agreement Product(s) for resale in such country
[ *** .]

         (c) The price initially payable by the Distributor to Biomatrix for
each unit of the Agreement Product during each month of each Agreement Year
shall be the Minimum Price applicable to sales in such country (subject to
adjustment at the close of each applicable Contract Quarter and Agreement Year
in accordance with Section 7.2(e) below).

         (d) Within [ *** ] after the end of each month of each
Agreement Year for each country in the Territory, the Formula Price for the

the applicable Minimum Price for such Agreement Year for such country, an
adjustment resulting from the [ *** ] with respect to all units of the
Agreement Product sold by the Distributor (and its Affiliates and
Subdistributors) in such country during such monthly period, such payment to be
made [ *** ] after the end of the month following such monthly period.

         (e) Within [ *** ] after the end of each Contract Quarter and Agreement

Product sold by the Distributor in such country during such Contract Quarter and
Agreement Year, such payment to be made within [ *** ] after the end of such 
[ *** ] period following the end of such Contract Quarter and Agreement Year. 
The price calculated annually in this manner shall be the final price payable
for all units of the Agreement Product sold by the Distributor, any Affiliates
or Subdistributors of Distributor during such Agreement Year. For the avoidance
of doubt, the aggregate amount payable by Distributor for the Agreement
Product(s) and any Improved Agreement Product(s) in any country for any
Agreement Year shall in no event be lower than the Minimum Price multiplied by
the total units sold in such Agreement Year in such country.

         (f) Within [ *** ] following the end of each calendar month in each
Agreement Year, the Distributor shall submit to Biomatrix written reports
detailing the units and value of the Distributor's, Affiliates' and
Subdistributors' Net Retail Sales and aggregate number of units sold of the
Agreement Product and any Improved Agreement Product(s) in each country in the
Territory during the immediately preceding calendar month.

         (g) Within [ *** ] following the end of each Agreement Year, the
Distributor shall submit to Biomatrix written reports detailing the
Distributor's and its Affiliates' and Subdistributors' sales of the Agreement
Product and any Improved Agreement Product(s) during the immediately preceding
Agreement Year, which reports shall contain the Net Retail Sales of the
Agreement Product and any Improved Agreement Product(s) in each country in the
Territory, and the aggregate number of units of the Agreement Product and any
Improved Agreement Product(s) sold in each country in the Territory during the
applicable Agreement Year.

         (h) All purchases of the Agreement Product and any Improved Agreement
Product(s) hereunder shall be billed and paid in Dollars within [ *** ] after
the later of the date of delivery or the date of the Distributor's receipt of

        7.3.   Sales and Supply Forecasts; Accounts.

         (a) Exhibit D, which shall be supplied by the Distributor within
[ *** ] of the Effective Date, sets forth a sales forecast of units of the
Agreement Product in the Territory for the first year after the Effective Date.

         (b) Within [ *** ] after the end of each month, the Distributor shall
provide to Biomatrix an updated rolling twelve (12) month monthly supply
forecast for all unit sizes of the Agreement Product in the Territory. Each such
supply forecast described in this subsection (b) is referred to herein as a
"Supply Forecast"; provided, that updated Supply Forecasts shall not vary
(whether up or down) from the immediately preceding Supply Forecast by more than
[ *** ] with respect to each month covered by such preceding Supply Forecast.

        (c) The Distributor shall maintain, and shall require its Affiliates and
Subdistributors to maintain, books of account with respect to sales of the
Agreement Product in the Territory by it and its Affiliates and Subdistributors.
Biomatrix shall have the right, not more than once during each calendar year, to
have an independent accountant selected and retained by Biomatrix (reasonably
acceptable to the Distributor, provided that any "big six" accounting firm shall
be deemed reasonable) to inspect and examine such books of the Distributor, its
Affiliates and Subdistributors during regular business hours for the purpose of
verifying the statements of the aggregate Net Retail Sales of all Dermal Tissue
Augmentation Products for all purposes hereunder, including verification of
Formula Price and the royalties described in Section 8. The cost of each such
audit shall be borne by Biomatrix unless a material error is discovered in the
course of such audit, in which case the cost shall be borne by the Distributor.
For purposes of this Section 7.3(d), a material error shall be defined as an
understatement of five percent (5%) or more of the aggregate amount owed to
Biomatrix with respect to sales of Dermal Tissue Augmentation Products in a
country in the Territory. Any additional payments required as a result of such
inspection and examination shall be immediately paid to Biomatrix and shall bear
interest from the date such amount would otherwise have been paid until the date
of actual payment at the rate per annum set forth in Section 20. Such
independent accounting firm shall conduct such inspections and examinations
under conditions of confidentiality.

         7.4. Shipment and Delivery; Packaging.

         (a) Biomatrix or an Affiliate of Biomatrix shall arrange for shipment
to the Distributor of the Agreement Product and any Improved Agreement
Product(s) ordered by the Distributor [ *** ]. The Distributor shall
pay all customs duties, sales taxes and other governmental charges relating to
the Agreement Product and any Improved Agreement Product(s), and shall be solely
responsible for clearing such products through customs throughout the Territory.

                                      -20-


         (b) The Distributor shall submit a firm purchase order setting forth
the quantities, delivery date and shipping instructions with respect to each
shipment of the Agreement Product and any Improved Agreement Product(s), such
purchase orders to be received by Biomatrix at least [ *** ] prior to the
requested delivery date; provided that the Distributor shall not submit any
purchase order for fewer than [ *** ] units of the Agreement Product or the
Improved Agreement Product(s) (although multiple delivery sites for purchase
orders shall be allowed). Biomatrix shall use commercially reasonable efforts
but shall have no obligation to supply Distributor with quantities of the
Agreement Product(s) and Improved Agreement Product(s) in excess of the amounts
in the then current Supply Forecast for the relevant monthly period. For
avoidance of doubt, so long as Biomatrix supplies Distributor with quantities of
the Agreement Product and Improved Agreement Product(s) as set forth in the
Supply Forecast, then Biomatrix shall not be deemed to be in default under this
section or any other provision of this Agreement relating to Biomatrix's supply
obligations. In addition to the foregoing, within [ *** ,] in consideration
for which units the Distributor shall pay to Biomatrix a price of [ *** ] per
unit.

         (c) Biomatrix agrees that with respect to languages for packaging for
the European Territory three separate forms of packaging shall be made
available, as applicable, as follows:

                  (i) Northern Europe - English, Dutch, French, German and
                  Italian;

                  (ii) Southern Europe - English, Italian, Spanish, Portuguese
                  and Greek; and

                  (iii) Scandinavia - English, Swedish, Norwegian, Danish and
                  Finnish.

         (d) Each unit of the Agreement Product and any Improved Agreement
Products shipped to the Distributor shall have, as of the time of delivery, a
remaining shelf life of no less than [ *** ] less than the maximum shelf life
for such product, as approved by the United States Food and Drug Administration.
Biomatrix shall continually use its best efforts at all times during the term
hereof to lengthen to [ *** ] the shelf life of the Agreement Product and any
Improved Agreement Products to the extent supported by stability data.
Biomatrix' "best efforts" in this section shall mean that Biomatrix shall use
such methods, exercise such degree of effort and diligence, and adhere to such
standards as are commercially reasonable.

         7.5. Title. Legal title to all quantities of the Agreement Product and
any Improved Agreement Product(s) sold hereunder shall remain in Biomatrix until
delivery of the Agreement Product and any Improved Agreement Product(s) to
Distributor or its agent and acceptance thereof and upon such delivery and
acceptance the title to such Agreement

Product and any Improved Agreement Product(s) shall, without further action, be
transferred to and vested in the Distributor.

         7.6. Risk of Loss. Biomatrix shall bear all risk of loss of, or damage
to, all units of the Agreement Product and any Improved Agreement Product(s) to
the extent the same is in its possession or the possession of its Affiliates,
nominees or agents. The Distributor shall bear all risk of loss of, or damage
to, all units of the Agreement Product and any Improved Agreement Product(s)
after delivery to a common carrier for shipment to the Distributor in accordance
with Section 7.4.

         7.7. Acceptance. [ *** .] All units of the Agreement Product and
Improved Agreement Products delivered to Distributor pursuant to this Agreement
shall be [ *** ,] the specifications listed in Exhibit A. Any non-conformity
which arises after acceptance by Distributor directly associated with product
specification shall be the responsibility of Biomatrix unless such
non-conformity is due to improper storage conditions subsequent to delivery of
the Agreement Product. All other non-conformities of the Agreement Product shall
be the responsibility of the Distributor. Biomatrix and the Distributor agree to
consult with each other in order to resolve the discrepancy between each other's
determinations. If such consultation does not resolve the discrepancy, the
parties agree to nominate a reputable independent laboratory, acceptable to both
parties, that shall carry out tests on representative samples taken from such
shipment, and the results of such tests shall be binding on the parties.
Biomatrix shall at its expense replace any such shipment to the extent that it
does not conform to the Agreement Product Specifications. All defective units of
the Agreement Product or any Improved Agreement Product(s) shall be returned to
Biomatrix at the address set forth in Section 23 of this Agreement, accompanied
or preceded by a reasonably detailed statement of the claimed defect or
non-conformity and proof of date of purchase, and packed and shipped according
to instructions provided by Biomatrix. The shipping costs of any such returned
units shall be borne by Biomatrix, unless such units are determined not to be
defective under the terms of this Agreement, in which case such shipping costs
shall be borne by the Distributor.

         7.8. Purchase Orders. The provisions of this Agreement shall prevail
over any inconsistent statement or provisions contained in any document related
to this Agreement passing between the parties hereto including, but not limited
to, any purchase order, acknowledgment, confirmation or notice.

         Biomatrix represents and warrants that the Agreement Product and any
Improved Agreement Product(s) supplied to the Distributor hereunder shall:

         (a) conform to the Agreement Product Specifications; and

         (b) be manufactured, labelled, packaged and tested (while in the
possession or control of Biomatrix) in accordance with the applicable Product
License Approvals therefor and all applicable laws and regulations in the
Territory relating to the manufacture, labelling, packaging and testing of the
Agreement Product, and shall be manufactured for use for the indications
specified in the applicable Product License Approvals therefor.

         THE FOREGOING WARRANTY IS THE SOLE AND EXCLUSIVE WARRANTY GIVEN BY

OR SUBDISTRIBUTORS') CONDUCT IN RELATION THERETO OR TO EACH OTHER. NO
REPRESENTATIVE OF BIOMATRIX IS AUTHORIZED TO GIVE OR MAKE ANY OTHER
REPRESENTATION OR WARRANTY OR TO MODIFY THE FOREGOING WARRANTY IN ANY WAY.

         The limited warranty set forth in this Section 7.9 does not apply to
any non-conformity of the Agreement Product or any Improved Agreement Product(s)
resulting from (a) repair or alteration by any party other than Biomatrix or its
Affiliates, (b) misuse, negligence, abuse, accident, mishandling or storage in
an improper environment by any party other than Biomatrix or its Affiliates, or
(c) use, handling, storage or maintenance other than in accordance with
instructions and recommendations provided by Biomatrix or its Affiliates.

         Biomatrix's obligation with respect to units of the Agreement Product
and any Improved Agreement Product(s) which do not meet the warranty contained
herein is limited to replacement of such units of the Agreement Product or
Improved Agreement Product(s) as applicable, provided that such units are

terms of this Agreement.

         BIOMATRIX'S LIABILITY, AND THE EXCLUSIVE REMEDY, IN CONNECTION WITH THE
SALE OR USE OF THE AGREEMENT PRODUCT AND ANY IMPROVED AGREEMENT PRODUCT(S)

THEREOF, OR ARISING IN ANY WAY IN CONNECTION WITH THE PURCHASE OR USE OR
INABILITY TO USE THE AGREEMENT PRODUCT OR ANY IMPROVED AGREEMENT PRODUCT(S),
EVEN IF BIOMATRIX HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN NO
EVENT WHATSOEVER SHALL BIOMATRIX HAVE ANY LIABILITY, OBLIGATION OR
RESPONSIBILITY FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR EXEMPLARY
DAMAGES ARISING IN ANY WAY IN CONNECTION WITH THE AGREEMENT PRODUCT OR ANY

Tissue Augmentation Products (other than sales of the Agreement Product and any
Improved Agreement Product(s)) in all countries in the Territory on a
country-by-country basis, including any countries that are added to the
Territory after the Effective Date, [ *** .] Such royalty shall commence with
respect to each country in the Territory at the earlier of (a) the Launch of the
Agreement Product in such country or (b) the Launch date for such country set
forth on Exhibit B; provided that if a Launch is delayed due to Biomatrix's
failure to meet its supply obligations under Section 7.4, due to a force majeure
condition of Distributor or if the Distributor is not able to lawfully sell the
Agreement product in such country, such royalty with respect to any such country
shall not commence until Biomatrix meets its supply obligations, Distributor is
able to lawfully sell the Agreement Product in such country, or until such force
majeure condition ceases. Such royalty shall be paid by not later than [ *** ]
after the end of each Contract Quarter.

         8.2. Incremental Royalties. The Distributor shall pay to Biomatrix the
following annual royalties (the "Incremental Royalties") on the Distributor's
and its Affiliates' and Subdistributors' total incremental increases in Net
Retail Sales of all Dermal Tissue Augmentation Products (including the Agreement

based on the incremental increases, if any, in Net Retail Sales of all Dermal
Tissue Augmentation Products in such country in each Agreement Year over a base
year amount comprised of Net Retail Sales of Dermal Tissue Augmentation Products
in the twelve (12) months immediately preceding the first commercial sale of
either the Agreement Product or any Improved Agreement Product(s) in such

The Distributor's obligation to pay the Incremental Royalties shall cease with
respect to a country in the Territory in the event that the Distributor's rights
to sell, distribute, market and promote the Agreement Product and any Improved
Agreement Product have become non-exclusive with respect to such country
pursuant to Section 2.3 or have terminated pursuant to Section 3.2(d). The
Incremental Royalty shall be paid by not later than [ *** ] after the end of
each Agreement Year. For the avoidance of doubt, if the Distributor had no sales
of any Dermal Tissue Augmentation Products in a country prior to the first
commercial sale of either the Agreement Product or any Improved Agreement
Product in such country, the Distributor shall be obligated to pay a [ *** ]
royalty on Net Retail Sales of all Dermal Tissue Augmentation products sold
after such first commercial sale.

         9. INDEMNIFICATION; CONFIDENTIALITY; PUBLIC ANNOUNCEMENT

         9.1. Indemnification from the Distributor. Subject to the provisions of
Section 9.3, the Distributor shall defend, indemnify and hold Biomatrix and its
Affiliates and their respective directors, officers, agents and employees
harmless from and against any and all liabilities, claims, damages and expenses
(including without limitation actual court costs and reasonable attorneys' fees
regardless of outcome) resulting from claims of third parties or arising out of:

agreed upon in writing by the parties hereto, after the relevant regulation is
amended), either party may terminate this Agreement upon written notice to the

        2.3. Conversion to Non-Exclusive Distributorship. In the event that (i)
in any Agreement Year after and including the third Agreement Year or (ii) from,

the date of a conversion to a non-exclusive distribution arrangement within the
Territory, the Distributor shall lose its rights hereunder to promote, market,
sell and distribute within the Territory any Improved Agreement Product(s)
commercialized on or after such date. Notwithstanding the foregoing, the
Distributor shall retain the exclusive right to use all trademarks under which
the Distributor launched the Agreement Product or any Improved Agreement
Product(s) in the Territory.

        3.     TERM AND TERMINATION.

        3.1.   Effective Date.  This Agreement shall take effect as of the 
               Effective Date.

        3.2.   Term.

        (a) Unless this Agreement is sooner terminated in accordance with the
provisions of this Agreement, the term of the appointment hereunder for shall
commence on the first day of the first Agreement Year and shall end on the last
day of the tenth (10th) Agreement Year (the "Initial Term").

        (b) Unless this Agreement is sooner terminated in accordance with the
provisions of this Agreement, the appointment of the Distributor hereunder as
exclusive distributor of the Agreement Product shall be renewable by the
Distributor, at its option, upon written notice to Biomatrix received at least
ninety (90) days prior to the end of the Initial Term, for an additional
consecutive term of five (5) years following the date of expiration of the
Initial Term, provided that the Distributor shall only be entitled to exercise
such renewal option if as of the date of expiration of the Initial Term the
Distributor is not in material breach of any of its obligations under this
Agreement. Thereafter, the appointment of the Distributor as exclusive
distributor of the Agreement Product shall be renewable upon the expiration of
such additional five (5) year term, upon written notice to Biomatrix received at
least ninety (90) days prior to the end of such term for one additional
consecutive renewal term of five (5) years provided that, as of the date of
expiration of the first renewal term, the Distributor is not in material breach
of any of its obligations under this Agreement. For the avoidance of any doubt,
Distributor's rights with respect to any Improved Agreement Product(s)
commercialized after the tenth anniversary of the Effective Date shall terminate
upon the tenth anniversary of the Effective Date. Subject to the terms of this
Agreement, Distributor shall have the right to continue to sell the Agreement
Product and any Improved Agreement Products it is then currently selling.

        (c) This Agreement may be terminated by either party, by written notice
to the other party, in the event that (i) a mutual decision not to Launch the
Agreement Product in such country is reached or (ii) a Launch is not commenced
within the time period set forth on Exhibit B.

        (d) In the event that in any Agreement Year after and including the
third Agreement Year (and so long as (i) no force majeure condition of
Distributor exists at such time pursuant to Section 20, (ii) Biomatrix has met
its supply obligations under Section 7.4,


***Confidential portions have been omitted and filed separately with the

and (iii) Distributor is able to lawfully sell the Agreement Product and any
Improved Agreement Product(s) in the Territory), the Distributor's Net Retail
Sales of the Agreement Product and any Improved Agreement Product(s) in the
Territory comprise less than seven and one-half percent (7-1/2%) of its Net
Retail Sales in the Territory of all Dermal Tissue Augmentation Products,
including the Agreement Product and any Improved Agreement Product(s), the
Distributor's distribution rights (including, without limitation, its right to
use the Trademarks) under this Agreement for the Agreement Product and any
Improved Agreement Product(s) in the Territory shall terminate upon ninety (90)
days notice, but in any event not later than one hundred and twenty (120) days
after the end of the applicable Agreement Year, at the election of Biomatrix;
provided, however, that Distributor may cure a shortfall of Net Retail Sales for
an Agreement Year by paying to Biomatrix an amount equal to twenty-five percent
(25%) of the total dollar amount of such shortfall of Net Retail Sales in such
Agreement Year; further provided that, at Biomatrix's election, Biomatrix may
refuse to allow such cure if Distributor has taken advantage of such cure
provision in each of the two preceding Agreement Years. By way of example, if
Distributor's Net Retail Sales of all Dermal Tissue Augmentation Products in the
Territory in a given Agreement Year were $10,000, and Distributor's Net Retail
Sales of the Agreement Product in the Territory in such Agreement Year were
$500, then Distributor could cure such shortfall and prevent termination by
paying Biomatrix $62.50. Upon any such termination of the Distributor's
distribution rights in the Territory, the Distributor's obligation to pay any
royalties pursuant to Sections 8.1 and 8.2 for any sales in the Territory after
such termination shall cease, but the Distributor shall remain obligated to pay
all such royalties for sales in the Territory accrued prior to such termination.

        (e) Notwithstanding any other provision of this Agreement to the
contrary, Biomatrix may terminate this Agreement at any time prior to receipt of
the Approved Letter (as defined hereafter) from the U.S. Food and Drug
Administration if Distributor is in material breach of the International
Agreement, which material breach has not been cured within thirty (30) days
after written notice of such breach is received by Distributor. The parties
expressly agree that Distributor's failure to meet or adhere to the launch
schedule for the Agreement Product for each country as set forth in the
International Agreement shall be deemed a material breach of the International
Agreement except to the extent that Distributor's failure to meet such launch
schedule is due to (i) Biomatrix's failure to meet its supply obligations under
the International Agreement, (ii) a force majeure condition of the Distributor,
or (iii) it being unlawful for the Distributor to sell the Agreement Product or
any Improved Agreement Product in the Territory, provided that such unlawfulness
is not the result of any act or failure to act of the Distributor.

        (f) Notwithstanding any other provision in this Agreement to the
contrary, the Distributor may terminate this Agreement upon notice to Biomatrix
of the Distributor's decision not to pay the fee called for in Section 7.1(b).

       3.3.   Inventory.

        (a) Upon termination of this Agreement for any reason, Biomatrix shall
have the right (but not the obligation) to repurchase all or part of the
inventory of the Agreement Product and any Improved Agreement Product(s) held by
the Distributor or its Affiliates.

        (b) The price for inventory to be repurchased by Biomatrix pursuant to
Section 3.3(a) above shall be the landed cost thereof actually paid by the
Distributor to Biomatrix. With respect to any quantities not repurchased by
Biomatrix, the Distributor shall have the right to sell such inventory of the
Agreement Product and any Improved Agreement Product(s), in its usual and
customary manner, in the ordinary course of business, for a period of six (6)
months following termination of this Agreement and notwithstanding such
termination the terms and conditions of this Agreement shall apply to such
sales.

        3.4. Insolvency. This Agreement may be immediately terminated by either
party, upon giving written notice to the other party, in the event that the
other party shall become insolvent or be declared bankrupt by a court of
competent jurisdiction or shall be the subject of any reorganization (other than
a corporate reorganization effected in the ordinary course of business and not
arising out of any insolvency) or winding up, receivership or dissolution,
bankruptcy or liquidation proceeding, or any proceeding or action similar to one
or more of the above, in which case termination shall be effective upon such
written notice. The failure of either party to give notice of termination upon
obtaining knowledge of any such event shall not be interpreted as a waiver of
such party's rights under this Section 3.4, and such party reserves the right to
exercise any such rights at any time after the occurrence of any such event.

        3.5. Breach. This Agreement may be terminated by either party if the
other party shall breach any of its payment obligations hereunder or if
Distributor shall commit a material breach of any of its warranties, covenants,
conditions, obligations or agreements contained herein, provided that such
breach shall continue for a period of thirty (30) days (ten (10) days in the
event that such breach is the failure of the Distributor to pay the fee called
for in Section 7.1(b)) after written notice thereof and provided further that
such termination shall be immediately effective upon further written notice to
that effect to the breaching party after its failure to cure such breach within
such applicable notice period. For avoidance of doubt, the parties agree that if
a Launch is not reached within thirty days after the time period set forth on
Exhibit B, then either party may terminate this Agreement (provided that such
failure to reach a Launch is not due to (i) a force majeure condition of the
Distributor, (ii) Biomatrix's failure to meet its supply obligations under
Section 7.4, or (iii) it being unlawful for the Distributor to sell the
Agreement Product or any Improved Agreement Product in the Territory, provided
that such unlawfulness is not the result of any act or failure to act of the
Distributor).

        3.6. Certain Rights Upon Termination. Upon termination of this Agreement
for any reason whatsoever, Biomatrix shall have the following rights:


<PAGE>   56
                                      -10-

instruments necessary in order to transfer to the fullest extent permitted under
applicable law all registrations and Product License Approvals, or applications
therefor, for the Agreement Product or any Improved Agreement Product(s) to
Biomatrix or any Person nominated by Biomatrix.

        3.7.   Effects of Termination.

        (a) Upon termination of this Agreement for any reason, the Distributor
shall immediately discontinue making any representations regarding its status as
a distributor for Biomatrix and shall immediately cease conducting any
activities with respect to the marketing, promotion, sale or distribution of the
Agreement Product and any Improved Agreement Product(s), provided, however, that
the Distributor shall be permitted to sell inventory not repurchased by
Biomatrix in accordance with Section 3.3.

        (b) Termination of this Agreement shall not affect obligations of either
party that may have accrued prior to the effective date of termination. Subject
to Clause 3.8 below, termination of this Agreement shall be in addition to, and
shall not be exclusive of or

<PAGE>   57
                                      -11-


prejudicial to, any other grounds for termination or rights or remedies at law
or in equity which either party may have on account of any default of the other

        3.8. Waiver. The Distributor hereby waives, to the extent it is able to
do so under the laws of the United States and other applicable law, any

the rights available to it hereunder in the event of such termination are
adequate and reflect the agreement of the parties. The Distributor shall not
have any right to claim any indemnity for goodwill or lost profits or any
damages arising from the rightful termination of this Agreement in accordance
with the terms hereof.

        4. PAYMENTS. All payments hereunder shall be made in Dollars. Payments
to Biomatrix shall be wired to an account designated by Biomatrix and the costs
of any such remittance shall be borne by the Distributor.

        5. WITHHOLDING. All payments to be made by the Distributor under this
Agreement shall be made in full, free and clear of and without any deduction of
or withholding for or on account of any taxes levied in any country of the
Territory or elsewhere; provided that if the Distributor shall be required by
law to make any deduction or withholding from any payment to Biomatrix then:

        (a) the Distributor shall ensure that such deduction or withholding does
not exceed the minimum legal liability therefor; and

        (b) not later than five (5) days before each deduction or withholding of
any taxes, the Distributor shall forward to Biomatrix such documentary evidence
as may be required by Biomatrix in respect of the proposed deduction,
withholding or payment; and

        (c) prior to any deduction or withholding the parties shall attempt in
good faith to agree upon revised mutually acceptable pricing and/or payment
terms.

        6.     TRADEMARKS; AGREEMENT PRODUCT MARKING; PROMOTIONAL INFORMATION.

        6.1. Trademarks. Subject to the provisions of Section 3.6, Biomatrix
hereby licenses to the Distributor the right to use, and hereby requires solely

        (a) The parties shall attempt in good faith to agree in writing, prior

       (b) Within [ *** ] after the end of each month of each Agreement
Year in the Territory, the Distributor shall provide to Biomatrix an updated
rolling twelve (12) month monthly supply forecast for all unit sizes of the

of each such audit shall be borne by Biomatrix unless a material error is
discovered in the course of such audit, in which case the cost shall be borne by
the Distributor. For purposes of this Section 7.3(d), a material error shall be
defined as an understatement of five percent (5%) or more of the aggregate
amount owed to Biomatrix with respect to sales of Dermal Tissue Augmentation
Products in the Territory. Any additional payments required as a result of such
inspection and examination shall be immediately paid to Biomatrix and shall bear
interest from the date such amount would otherwise have been paid until the date
of actual payment at the rate per annum set forth in Section 20. Such
independent accounting firm shall conduct such inspections and examinations
under conditions of confidentiality.

        7.4.   Shipment and Delivery; Packaging; Shelf Life.

the requested delivery date; provided that the Distributor shall not submit any
purchase order for fewer than [ *** ] units of the Agreement Product or the
Improved Agreement Product(s) (although multiple delivery site for purchase
orders shall be allowed). Biomatrix shall have no obligation to supply
Distributor with quantities of the Agreement Product(s) and Improved Agreement
Product(s) in excess of the amounts in the then current Supply Forecast for the
relevant monthly period.

Biomatrix shall continually use its best efforts at all times during the term
hereof to lengthen to [ *** ] the shelf life of the Agreement Product and any

Agreement Products delivered to Distributor pursuant to this Agreement shall be

after acceptance by Distributor directly associated with Product specification
shall be the responsibility of Biomatrix unless such non-conformity is due to
improper storage conditions subsequent to delivery of the Agreement Product. All
other non-conformities of the Agreement Product shall be the responsibility of
the Distributor. Biomatrix and the Distributor agree to consult with each other
in order to resolve the discrepancy between each other's determinations. If such
