the date of a conversion to a non-exclusive distribution arrangement within the

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

        (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,

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:

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

the provisions of Section 3.3(b), (i) immediately upon termination to cease

to Biomatrix any documents or instruments reasonably requested by Biomatrix to
give full effect to the provisions of this Section 3.6.

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>   11
                                      -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
party.

        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
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

to Biomatrix shall be wired to an account designated by Biomatrix and the costs
of any such remittance shall be borne by the Distributor.

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:

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,

        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

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

        (d) Within [ *** ] after the end of each month of each Agreement Year,
the Formula Price for the Agreement Product shall be calculated, and, to the
extent that such Formula Price exceeds the applicable Minimum Price for such

respect to all units of the Agreement Product sold by the Distributor in the
Territory during such Contract Quarter and Agreement Year, such payment to be

manner shall be the final price payable for all units of the Agreement Product
sold by the Distributor or any Affiliate 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) 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 the Territory.

        (f) Within [ *** ] following the end of each calendar month in each
Agreement Year, the Distributor shall submit to Biomatrix written reports

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 the Territory, and the aggregate number of
units of the Agreement Product and any Improved Agreement Product(s) sold in the
Territory during the applicable Agreement Year.

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 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.

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
