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

exercise any such rights at any time after the occurrence of any such event.

         3.4. Breach. This Agreement may be terminated by either party if the

         3.6. Certain Rights Upon Termination. (a) Upon termination of this
Agreement for any reason whatsoever, other than pursuant to Section 3.1,
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

and clinical protocols (including without limitation, marketing information and
information relating to laboratory, animal and human studies), and related
regulatory approvals pertaining to the Products (the "Information") which are
possessed or controlled by Wyeth or any of its Affiliates, or which Wyeth or any
of its Affiliates has a right to review, access or use. Wyeth 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 rights. In addition, Wyeth agrees that it
shall, upon the request of Biomatrix, immediately inform all relevant regulatory
authorities that Wyeth is no longer a licensee of the Products and shall take
all action and execute and deliver all documents and instruments necessary in
order to transfer all Product Approvals, Reimbursement Approvals and price
approvals and other relevant documents relating to Products to Biomatrix or any
Person designated by Biomatrix.

         (b) Notwithstanding the provisions of Section 3.6(a), both parties in

         3.7.  Effects of Termination.

         (a) Subject to Wyeth's rights set forth in Section 3.2(a), upon
termination of this Agreement for any reason, other than pursuant to Section
3.1, Wyeth shall discontinue using the Trademarks or making any representations
regarding its status as a licensee of Biomatrix and shall cease conducting any
activities with respect to the marketing, promotion, sale or distribution of the
Products in the Territory and shall take such action as is necessary to
terminate Wyeth's registration as Biomatrix's licensee with any governmental
authority.

         (b) Termination of this Agreement shall not affect obligations of
either party that may have accrued prior to the effective date of termination or
any obligation

<PAGE>   12
                                      -12-



specifically stated to survive termination. Except to the extent limited by
Section 3.8, 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. Wyeth and Biomatrix hereby waive, to the extent they are
able to do so under applicable law, any statutory rights they may have or
acquire under the laws of the Territory in respect of the termination of the
relationship established hereby pursuant to the terms hereof, and agree that the
rights available to them hereunder in the event of such termination are adequate
and reflect the agreement of the parties. Neither Wyeth nor Biomatrix nor any of
their respective Affiliates shall have any right to claim any indemnity for
goodwill or loss thereof, lost profits, loss of prospective compensation,
expenditures, investments, leases or any type of commitment made in connection
with the business of such party in reliance on the existence of this Agreement
or any damages arising from the termination of this Agreement by the other party
in accordance with the terms hereof.

         4. PAYMENTS; EXCHANGE RATE. All payments hereunder shall be made in
U.S. Dollars. Payments to Biomatrix shall be wired to an account in a bank
designated by Biomatrix and the costs of any such remittance shall be borne by

         5. WITHHOLDING. All payments to be made by Wyeth 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 the Territory or elsewhere;
provided that if Wyeth shall be required by law to make any deduction or
withholding from any payment to Biomatrix then:

         (i)      Wyeth shall ensure that such deduction or withholding does not
                  exceed the minimum legal liability therefor;

         (ii)     at least thirty (30) days prior to the first deduction or
                  withholding, Wyeth shall notify Biomatrix thereof, and the
                  parties shall negotiate in good faith adjustments to the
                  payments hereunder in order to minimize or eliminate such
                  deduction or withholding, provided that the total payments by
                  Wyeth shall not increase; and

         (iii)    Wyeth shall forward to Biomatrix such documentary evidence as
                  may be available in respect of each deduction, withholding or
                  payment together with each payment or promptly thereafter.

6.       DEVELOPMENT PROGRAM

         6.1. General. Commencing upon receipt of the necessary Product

         (b) The Development Fund shall not, unless otherwise agreed by the

                                        *

                           below, commencing the first Contract Year after
                           receipt of the necessary Product Approvals for sale
                           of the Initial Product in the United States; and

                  (ii)     Biomatrix shall be obligated to contribute an amount
                           equal to

                           sale of the Initial Product in the United States; and

                  (iii)    In the event the amounts required to be contributed
                           by Wyeth and Biomatrix under subparagraphs (i) and
                           (ii) above are less than the amount needed to fund
                           the Development Program as determined by the
                           Committee,


                                        *

                           Amounts advanced to the Development Fund

         (a) Both parties will, as the Committee shall determine, perform such
research and experimentation as the Committee shall determine toward the goal of
advancing the Development Program.

         (b) The Committee shall meet periodically to review and discuss in
detail the progress of the Development Program. The parties shall use their best
efforts to have the appropriate personnel attend and participate in each of such
meetings.

         (c) Each party acknowledges and agrees that, subject to the provisions
of Section 6 hereof, this Agreement is not an agreement for the development of
products other than Improvements and Extended Products; and, either party may
work, either independently or with one or more third parties, outside the scope
of this Agreement to develop other products, notwithstanding that such other
products may be directly competitive with and/or superior to any Products or
Extended Products developed hereunder.

         6.4. Expenses. Unless otherwise directed by the Committee, expenses for
Development Projects shall be charged as follows:

         (a) No senior management time of either Party shall be billed;

         (b) Actual third-party expenses shall be billed as incurred;

         (c) For services of Wyeth, including without limitation statistical and
monitoring services, for which there would be a clinical grant or which would
normally be performed by a third party, the parties agree that the amount
expensed by Wyeth shall be an amount equal to the clinical grant amount;
provided that such amount shall not exceed the amount that an independent third
party would charge to perform such services.

         (d) For services of Biomatrix, including without limitation
pre-clinical or statistical/regulatory activities, the parties agree that the
amount expensed by Biomatrix shall not exceed the amount an independent third
party would charge to perform such services.


         6.5. Ownership. (a) Biomatrix shall own all proprietary rights to all
Improvements and Extended Products (and any improvements thereto) that are
developed under the Development Program and/or using the Development Fund. To
the extent that employees of Wyeth may be inventors or joint inventors of any
Improvements or Extended Products or any other inventions under the Development
Program, Wyeth and its employees shall execute any and all necessary documents,
including without limitation, applications for letters patent and assignments,
to give effect to the intent of the parties that Biomatrix shall own all of the
foregoing properties. To the extent that Biomatrix employees are the only
inventors of any of these properties, then Biomatrix shall have the right to
apply for patent protection on these properties in its own name.

                                      -15-




         (b) Extended Products shall be encompassed within the terms of this
Agreement and the International License Agreement, the Supply Agreement and the
Trademark Agreement as they relate to Products. The parties agree that there
shall be no additional milestone payments relating to any such Extended Products
and that the Minimum Prices and Transfer Prices applicable to any such Extended
Products would be substantially equivalent to the Minimum Price and Transfer
Price applicable to the Initial Product unless the cost of manufacture of any
such Extended Products is materially different than the cost to manufacture the
Initial Product. If the parties are unable to agree upon any terms relating to
Extended Products, the matter shall be submitted for resolution under the
provisions of Section 9.9.

         (c) The parties agree that any Extended Products (to the extent that
the parties are able to negotiate terms for an Extended Product) shall have
their own Contract Years, Initial Term and Additional Periods separate and
distinct from the Contract Years, Initial Term and Additional Periods relating
to the Products on a country-by-country basis within the Territory.


         7. COMPETING PRODUCTS.

         7.1. Non-competition by Wyeth. In recognition of the rights granted by
Biomatrix to Wyeth and the other obligations of Biomatrix hereunder, Wyeth
agrees that it shall not, directly or indirectly (alone or with others), and it
shall ensure that its Affiliates shall not, directly or indirectly (alone or
with others), during the Non-competition Period, manufacture, sell, market,
distribute or promote a Competing Product in the Territory;

                                        *

If Wyeth

                                        *


Wyeth agrees

                                        *

Wyeth acknowledges and agrees that, in the event of a breach or threatened
breach by Wyeth of its obligations under this Section 7.1, Biomatrix will have
no adequate remedy at law, and accordingly shall be entitled to injunctive or
other appropriate equitable remedies against such breach or threatened breach in
addition to any other remedies which Biomatrix may have.

         7.2. New Products. Notwithstanding any provision in this Agreement or
in the International License Agreement to the contrary, if Biomatrix develops a
New Product and Wyeth is an exclusive licensee of any Product or Extended
Product in a country, Biomatrix shall not commercialize any such New Product in
any country in which Wyeth is an exclusive licensee under this Agreement of any
Product or Extended Product until the following conditions have been satisfied:

              (i)   Biomatrix has made a commercially reasonable written offer
              to Wyeth to participate with Biomatrix in the development and
              marketing of such New Product;

              (ii)  Wyeth has failed to accept such written offer or make its
              own commercially reasonable written offer within  *  of its
              receipt of such offer; and

              (iii) The parties shall have negotiated in good faith to attempt
              to reach agreement based upon Biomatrix's and/or Wyeth's offer for
              a period  *

         In the event that the parties fail to reach an agreement pursuant to
this Section 7.2 within  *  of Wyeth's receipt of Biomatrix's first written
offer, then Biomatrix shall not be restricted by this Agreement or the
International License Agreement in the exercise of any rights that Biomatrix
might otherwise have to develop and/or commercialize any New Product to which
such offer relates; provided that  *

         Nothing in this Section 7.2 shall be construed, by implication or
otherwise, (i) to effect any sale or license of proprietary Biomatrix technology
(including any new Products), (ii) to grant any license relating to Biomatrix's
proprietary methods of formulating, fabricating and manufacturing Products,
Extended Products or New Products, or (iii) to grant Wyeth any rights in or to
any proprietary technology or Patents or Trademarks of Biomatrix.

manufacturing know-how, patents, data, test results, techniques, processes,
procedures, raw materials, dealer, supplier and customer lists, the Information
described in Section 3.6, pre-clinical and clinical protocols or any
improvements thereof of the Discloser ("Confidential Information") is
confidential, and shall be held in trust by the Recipient for the exclusive
benefit of the Discloser. Unless otherwise agreed to in writing by the
Discloser, the Recipient shall not at any time, either during or subsequent to
the term of this Agreement, use for itself (other than in accordance with the

non-use as set forth herein, any Confidential Information or any other
confidential or proprietary information of the Discloser of which the Recipient
may acquire knowledge; provided, however, that the confidentiality,
non-disclosure and non-use provisions contained in this Section 8.1 shall not
apply to any information or data to the extent that the Recipient:

         (i)      shall demonstrate by written evidence that such information or
                  data is known generally to persons in the trade through no act
                  or omission of the Recipient or any of its Affiliates;

         (ii)     is required by any government authority to disclose such
                  information or data, including without limitation for the

                  or data was disclosed to or created by it or its Affiliates on
                  a non-confidential basis from a source other than the
                  Discloser or its Affiliates and that such disclosure or
                  creation did not constitute a breach of any applicable
                  confidentiality obligations.

All Confidential Information shall be immediately returned to the Discloser upon
termination of this Agreement, along with any copies, reproductions, digests,
abstracts or the like of all or any part thereof in the Recipient's possession

return and/or destruction of the Confidential Information. Such return (and
destruction) will not affect the Recipient's obligations hereunder, which shall
survive indefinitely or, if a definite period is required under applicable law,
until five (5) years after termination or expiration of this Agreement.
Notwithstanding anything herein to the contrary, the provisions of this Section
8.1 shall be subject to Biomatrix's rights under Section 3.6.

seek, in any state or federal court in the State of New Jersey, equitable relief

effect.


         21. FORCE MAJEURE. Each of the parties shall be excused from the
performance of its obligations hereunder in the event such performance is
prevented by force majeure, and such excuse shall continue as long as the
condition constituting such force majeure continues. For the purpose of this
Agreement, force majeure is defined as contingencies beyond the reasonable
control of either party, including, without limitation, acts of God, judicial or
regulatory action, war, civil commotion, destruction of production facilities or
materials by fire, earthquake or storm and labor disturbances (whether or not
any such labor disturbance is within the power of the affected party to settle)
or unavailability of supply materials. The party affected by force majeure shall
provide the other party with full particulars thereof as soon as it becomes
aware of the same (including its best estimate of the likely extent and duration

the establishment of the Product or Extended Product in the marketplace and the
* of the Product or Extended Product. * is not intended to be a substitute for
determining the Commercially Reasonable Efforts of Wyeth under this Section 2.2.

Wyeth shall promote the sale of Products and Extended Products through its sales
force, which shall receive training and support and have skills and resources
commensurate with those of Wyeth's sales force for other products which are of a
similar nature as the Products and Extended Products. Wyeth has no authority to
appoint any subagent, subdistributor, or other person to promote the sale of the
Products or Extended Products or to otherwise perform any of Wyeth's obligations

         2.3.     Conversion to Co-promotion or Co-exclusive License.

         (a)      Failure to Meet

                                        *

Sales Goals. In the event that Wyeth's cumulative Net Revenues from sales of
Products in the

                                       *


with respect to any Region set forth on Exhibit C shall fail to exceed the

                                       *

set forth opposite such Region on Exhibit C, then Biomatrix may,
at its option, elect to co-promote the Products and Extended Products or any
Improvement in such Region either itself (or through an Affiliate) or with a
designee (a "Designee") selling for Wyeth's account. Such co-promotion may be
either on a fixed cost reimbursement or performance/incentive basis as agreed
upon by the parties. Biomatrix shall make any such elections within

                                       *

after delivery to Wyeth of a notice of any such failure to meet such

                                       *

The parties agree that they will in good faith adjust such amounts on Exhibit
C if Wyeth can demonstrate that parallel imports of Products or other factors
such as competitive products being introduced, lower than anticipated reimbursed
price approval and other material external market factors had a material adverse
impact on its ability to achieve such amounts in any such Region. If Biomatrix
elects to convert this Agreement to a co-promotional arrangement with respect to
one or more Regions pursuant to the provisions of this Section 2.3, then
Biomatrix (or an Affiliate) or its Designee shall be compensated as follows:

                                       *


If Biomatrix elects to co-promote the Products and Extended Products in any
Region, then Biomatrix (or an Affiliate) or its Designee may co-promote under
the Trademark in such Region.

         (b) Failure to Meet Marketing Plan Goals. In the event that Wyeth's Net
Revenue from sales of Products in any Region in the Territory during the

                                        *

shall fail to exceed,
                                        *

of the projected Net Revenue set forth in the marketing plan prepared in
accordance with Section 8.8 for such Region, then Biomatrix may elect (i) to

threatened or ongoing Irreparable Breach, each party hereto shall be entitled to
seek, in any state or federal court in the State of New Jersey, equitable relief
of a kind appropriate in light of the nature of the ongoing threatened
Irreparable Breach, which relief may include, without limitation, specific
performance or injunctive relief; provided, however, that if the party bringing
such action is unsuccessful in obtaining the relief sought, the moving party
shall pay the non-moving party's reasonable costs, including attorney's fees,
incurred in connection with defending such action. Such remedies shall not be
the parties' exclusive remedies, but shall be in addition to all other remedies
provided in this Agreement.

         19. SEVERABILITY. In the event that any provision of this Agreement
shall be held by a court of competent jurisdiction or by any governmental body
to be invalid or unenforceable, such provision shall be deemed severable and the
remaining parts and provisions of this Agreement shall remain in full force and
effect.

         20. FORCE MAJEURE. Each of the parties shall be excused from the
performance of its obligations hereunder in the event such performance is
prevented by force majeure, and such excuse shall continue as long as the
condition constituting such force majeure continues. For the purpose of this
Agreement, force majeure is defined as contingencies beyond the reasonable
control of either party, including, without limitation, acts of God, judicial or
regulatory action, war, civil commotion, destruction of production facilities or
materials by fire, earthquake or storm and labor disturbances (whether or not
any such labor disturbance is within the power of the affected party to settle)
or unavailability of supply materials. The party affected by force majeure shall
provide the other party with full particulars thereof as soon as it becomes
aware of the same (including its best estimate of the likely extent and duration
of the interference with its activities), and will use its reasonable endeavors
to overcome the difficulties created thereby and to resume performance of its
obligations as soon as practicable.

         21. INTEREST. Any overdue amounts payable by either party hereunder
shall bear interest compounded monthly at the prime lending rate for U.S.
Dollars published from time to time in The Wall Street Journal plus 

                                       *

         24. EU REGULATIONS. It is the intention of the parties hereto that this
Agreement shall at all times qualify for the exemption from the provisions of

either (a) is available under EEC Regulation Number 1983/83, or (b) may

the conditions for qualifying for the exemption, set out in whichever of those
regulations may be in effect at the relevant time, or if any such regulation is
amended after the date of this Agreement so as to cause this Agreement to fail

Agreement as necessary in order to re-qualify for the exemption or notify the
Agreement.

a decision with respect to year sixteen must be made prior to the commencement
of year thirteen and decision with respect to year nineteen, and must be made
prior to the commencement of year sixteen.)

         (b) If any Additional Period supply arrangement is determined by the
parties to remain on an exclusive basis in a country in the Territory, then
Biomatrix shall supply Wyeth exclusively and Wyeth shall purchase all of its
requirements for the Product for such country from Biomatrix.

         (c) If any Additional Period supply arrangement is determined by either
party to be on a non-exclusive basis in a country in the Territory, then
Biomatrix may supply other parties with the Product for sale in the Territory
(excluding the right to use the Trademark, provided that Wyeth still has the
exclusive right to use the Trademark in any applicable country under either of
the License Agreements) and Wyeth may purchase all or part of its requirements
for the Product from third parties.

commercially reasonable efforts to ensure that they shall have the manufacturing

                                        *

sales forecasts for sales of Units of Products in each country in the Territory
for each of the

                                        *

Contract Years.  Within

                                        *

after the expiration of each of the

                                        *

during any Contract Year, Wyeth shall provide to Biomatrix a forecast of Units
of Products and Extended Products in each country in the Territory for the

                                        *

period (including a year-by-year breakdown) following the delivery of such
report. Such forecasts shall be prepared by Wyeth in good faith, using
reasonable assumptions applicable to each country in the Territory, regarding
the patient population, market penetration, competition, product label and the
price to third parties resulting from Reimbursement Approvals (as defined in the
License Agreements) in the countries in the Territory. Each such sales forecast
described above is referred to herein as a "Long Range Forecast." Such Sales
Forecast may be

                                        *


         5.2      Supply Forecasts.  Within

an updated

                                        *

supply forecast (the "Supply Forecast") and the

                                        *

shall be consistent with the firm purchase orders previously delivered pursuant
to Section 7, provided that commencing in

                                        *

after the U.S. Launch Date Biomatrix's obligation to supply Products under the
Supply Forecasts shall not increase

                                        *

The Supply Forecast shall supersede the Long Range Forecast for any applicable
period.

         5.3 Minimum Purchases. Wyeth hereby agrees that

                                        *

                                        *

for Syringes in each Region in the Territory as set forth on Exhibit C as of the
Effective Date.

         5.4 Failure to Reach Minimum Purchases. If Wyeth fails to reach any of
the aggregate minimum purchase requirements in a Region in the Territory in any
Contract Year (other than as a result of a failure by Biomatrix to supply the
Product in accordance with the terms hereof), then, notwithstanding such failure
and subject to Wyeth not being in breach of any other provisions of the
applicable agreements, Wyeth shall have the right, in its sole discretion, to
maintain this Agreement, the License Agreements, and the Trademark License
Agreement by paying to Biomatrix within thirty (30) days after the end of such
Contract Year $12 U.S. Dollars for each Unit of Product by which Wyeth failed to
meet the applicable minimum purchase requirement but Biomatrix shall not be
required to deliver any Product in exchange for any such payment. If Wyeth fails
to meet a minimum purchase requirement and, in its sole discretion, chooses not
to make the payment to Biomatrix contemplated by this Section 5.4, then
Biomatrix may at its option upon thirty (30) days prior written notice to Wyeth,
terminate this Agreement and the applicable License Agreement as it applies to
such Region.

         5.5 Records and Audits. Wyeth shall maintain books of account with
respect to its sales of the Products and Extended Products in each country in
the Territory. Biomatrix shall have the right, not more than once during each
calendar year, to have an independent accountant selected and retained by
Biomatrix to inspect and examine such books of Wyeth during regular business
hours for the purpose of verifying the statements of the aggregate Net Revenues
resulting from sales of Products and Extended Products and determining the
correctness of the Formula Price Percentages and Per Unit Formula Prices. 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
Wyeth. As used herein, a "material" error is one which results in an
underpayment to Biomatrix greater than five percent (5%) actually due. 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 23 hereof.


         6. SHIPMENT AND DELIVERY. Biomatrix shall arrange for shipment and
invoicing to Wyeth of Product and Extended Products ordered by Wyeth via common
carrier,

                                        *

Wyeth shall pay all customs duties, sales taxes and other governmental charges
relating to the importation and sale of Product and Extended Products, and shall
have all responsibility for storing and clearing Product and Extended Products
through customs and for all other importation requirements. No VAT or customs
duty number shall be assigned to any Product or Extended Products without the
prior written consent of Biomatrix.


         7. FIRM ORDERS. Wyeth shall submit a firm purchase order setting forth
the quantities, delivery date and shipping instructions with respect to each
shipment of Product or Extended Product, such purchase orders to be received by
Biomatrix at least


                                        *

all units of Products and Extended Products until such Products and Extended
Products have been delivered to the port of entry within the Territory. Wyeth
shall bear all risk of loss of, or damage to, all units of Products after
delivery by Biomatrix to the port of entry.

         9. ACCEPTANCE. Biomatrix shall complete a certificate of analysis for
each product batch contained in a shipment to Wyeth in accordance with the test
requirements set forth in the applicable Product Specifications. Biomatrix shall
include each certificate of analysis with the respective shipment to Wyeth.
Should Wyeth notify Biomatrix within

                                       *

of the receipt of any shipment of Product or Extended Product that such Product
or Extended Product does not conform to the applicable Product Specifications
therefor, Biomatrix and Wyeth agree to consult with each other in order to
resolve the discrepancy between each other's determinations regarding any
possible defect. 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, and the
party whose determination was in error as determined by such laboratory shall
pay all costs associated with such testing. Biomatrix shall at its expense
replace any such shipment to the extent that it does not conform to applicable
Product Specifications. All defective Units shall be returned to Biomatrix at
the address set forth above, 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 Wyeth.

         10. 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.

REMEDY, IN CONNECTION WITH THE SALE OR USE OF PRODUCTS OR EXTENDED PRODUCTS
(WHETHER BASED ON CONTRACT, NEGLIGENCE, BREACH OF WARRANTY, STRICT LIABILITY OR

         18. FURTHER ASSURANCES. The parties hereto agree to execute such
further or other documents and assurances as are necessary from time to time in
order to give effect to the provisions of this Agreement.

         19. ASSIGNMENT. The rights and obligations of the parties hereto shall
inure to the benefit of and shall be binding upon the authorized successors and

consent of the other party, take any of the following actions (collectively
referred to herein as an "Assignment"): (i) assign or transfer its rights or
obligations under this Agreement, (ii) license or sublicense any of its rights
or obligations under this Agreement, or (iii) designate another person to
perform all or part of its obligations under this Agreement or have all or part

         20. GOVERNING LAW; INJUNCTIVE RELIEF.

         20.1 Governing Law and Dispute Resolution. This Agreement and the
respective rights and obligations of the parties shall be governed by and
construed in accordance with the internal and substantive laws of the State of
New Jersey, United States of America (without regard to principles of conflicts
of laws). The parties hereby agree that the United Nations Convention on
Contracts for the International Sale of Goods shall not apply to this Agreement
or any other document contemplated hereby. In the event of any dispute touching
or concerning this Agreement, the parties hereby agree to submit such dispute to
their respective chief
<PAGE>   19
                                      -19-



executive officers or their designees by notice delivered in accordance with the
provisions of Section 25 hereof. Each of the parties agrees that any suit
relating to this Agreement may be brought in the courts of the State of New
Jersey or any federal court and service of process in any such suit being made
by mail at the address specified in Section 25. Each party hereby waives any
objection that it may now or hereafter have to the venue of any such suit or any
such court or that such suit is brought in an inconvenient court.

         20.2 Injunctive Relief. Each of the parties hereto acknowledges and
agrees that damages will not be an adequate remedy for any material breach or
violation of this Agreement if such material breach or violation would cause
immediate and irreparable harm (an "Irreparable Breach"). Accordingly, in the
event of a threatened or ongoing Irreparable Breach, each party hereto shall be
entitled to seek, in any state or federal court in the State of New Jersey,
equitable relief of a kind appropriate in light of the nature of the ongoing
threatened Irreparable Breach, which relief may include, without limitation,
specific performance or injunctive relief; provided, however, that if the party
bringing such action is unsuccessful in obtaining the relief sought, the moving
party shall pay the non-moving party's reasonable costs, including attorney's
fees, incurred in connection with defending such action. Such remedies shall not
be the parties' exclusive remedies, but shall be in addition to all other
remedies provided in this Agreement.

         21. SEVERABILITY. In the event that any provision of this Agreement
shall be held by a court of competent jurisdiction or by any governmental body
to be invalid or unenforceable, such provision shall be deemed severable and the
remaining parts and provisions of this Agreement shall remain in full force and
effect.

         22. FORCE MAJEURE. Each of the parties shall be excused from the
performance of its obligations hereunder in the event such performance is
prevented by force majeure, and such excuse shall continue as long as the
condition constituting such force majeure continues. For the purpose of this
Agreement, force majeure is defined as contingencies beyond the reasonable
control of either party, including, without limitation, acts of God, judicial or
regulatory action, war, civil commotion, destruction of production facilities or
materials by fire, earthquake or storm and labor disturbances (whether or not
any such labor disturbance is within the power of the affected party to settle).
The party affected by force majeure shall provide the other party with full
particulars thereof as soon as it becomes aware of the same (including its best
estimate of the likely extent and duration of the interference with its
activities), and will use its best endeavors to overcome the difficulties
created thereby and to resume performance of its obligations as soon as
practicable.

         23. INTEREST. Any overdue amounts payable by either party hereunder
shall bear interest compounded monthly at the prime lending rate for U.S.
Dollars

the due date until the date of payment.

         24. NO PARTNERSHIP OR AGENCY. This Agreement and the relations hereby
established by and between Biomatrix and Wyeth do not constitute a partnership,
joint venture, agency or contract of employment between them.

         25. NOTICES. All communications in connection with this Agreement shall
be in writing and sent by postage prepaid first class mail, courier, or telefax,

General Counsel or to such other address as the addressee shall last have
designated by notice to the communicating party. The date of giving any notice
shall be the date of its actual receipt.

         26. EU REGULATIONS. It is the intention of the parties hereto that this
Agreement shall at all times qualify for the exemption from the provisions of
Article 85(1) of the Treaty of Rome dated 25 March 1957, as amended, which
either (a) is available under EEC Regulation Number 1983/83, or (b) may
otherwise be available under any other regulations or successor regulation
thereto. In the event that any provision of this Agreement is deemed to violate
the conditions for qualifying for the exemption, set out in whichever of those
regulations may be in effect at the relevant time, or if any such regulation is
amended after the date of this Agreement so as to cause this Agreement to fail
to qualify for the exemption, the parties hereto agree that they will, as soon
as it is practicable to do so, enter into good faith negotiations to amend this
Agreement as necessary in order to re-qualify for the exemption or notify the
Agreement.

         27. SURVIVAL. The provisions of Sections 11 and 12 of this Agreement
shall survive the termination or expiration of this Agreement (as the case may
be) and shall remain in full force and effect. The provisions of this Agreement
that do not survive termination or expiration hereof (as the case may be) shall,
nonetheless, be controlling on, and shall be used in construing and interpreting
the rights and obligations of the parties hereto with regard to, any dispute,
controversy or claim which may arise under, out of, or in connection with this
Agreement.

Wyeth-Ayerst Laboratories division (such entities are together defined herein as
"Wyeth").

         WHEREAS, Biomatrix and Wyeth are parties to that certain International
License Agreement (the "International License Agreement") and United States
License Agreement (the "U.S. License Agreement"), each dated as of February 7,
1997 (together, the "License Agreements"), pursuant to which (i) Biomatrix
agreed to sell and license to Wyeth, and Wyeth agreed to purchase and license
from Biomatrix, Products (as defined in the License Agreements) and Extended
Products and (ii) Biomatrix granted to Wyeth the right and license to use
certain trademarks owned by Biomatrix in any promotional materials used by Wyeth
to market the Products and Extended Products, all on the terms and conditions
set forth in the License Agreements;

         WHEREAS, Biomatrix is the owner of rights in, and the goodwill
associated with, the Trademark (as defined below); and

         WHEREAS, Biomatrix and Wyeth desire to enter into this Agreement for
purposes of licensing Wyeth to use the Trademark in the Territory (as defined in
each of the License Agreements, respectively).

         NOW, THEREFORE, the parties hereto agree as follows:

                  1. DEFINITIONS; RULES OF INTERPRETATION

                  1.1 Definitions. Unless otherwise specifically provided
herein, all defined terms herein shall have the meanings ascribed them in the
License Agreements in effect on the effective date of this Agreement. For
purposes of this Agreement, the term "Trademark" shall mean (i) the trademark
"Synvisc(R)" and each other mark, trademark or service mark described on Exhibit

                                      -2-



         1.2 Rules of Interpretation.

             (a) All definitions (whether set forth herein or by reference)
     shall apply equally to both the singular and plural forms of the terms
     defined. Whenever the context may require, any pronoun shall include the
     corresponding masculine, feminine and neuter forms. All references herein
     to Sections shall be deemed references to Sections of this Agreement unless
     the context otherwise requires.

             (b) In the event that any of the terms or provisions of this
     Agreement shall be in conflict with or be inconsistent with any of the
     terms or provisions of the License Agreements, the terms and provisions of
     this Agreement shall govern.


         2. GRANT OF LICENSE; ROYALTY.

         2.1 License. Subject to the terms and conditions of this Agreement,
Biomatrix grants to Wyeth, and Wyeth accepts from Biomatrix, the exclusive,
right and license (without the right to sublicense), for the term of this
Agreement, to use and display, and Wyeth shall use and display, the Trademark
solely in connection with the sale, distribution, marketing, advertising and
promotion of Products and Extended Products in the Field in the Territory. Wyeth
agrees that it shall not use the Trademark at any time outside the Territory or
use any Trademark for any products other than the Products and Extended Products
within the Territory, or for any other purpose except as provided herein.

         2.2 Limitation of Rights. Wyeth shall have the right to use the
Trademark only in the manner and to the extent specifically permitted by this
Agreement. Biomatrix retains all rights not expressly granted to Wyeth in this
Agreement. If Wyeth's license to sell Products or Extended Products terminates
with respect to any country in the Territory then Wyeth's rights to use the
Trademark and all other product specific logos, slogans and other intangibles
used by Wyeth or its Affiliates in association with the sale of Products and
Extended Products (including all registrations relating thereto) shall terminate
with respect to such country and, subject to Wyeth's sell-out rights with
respect to inventory, Wyeth shall (i) immediately with respect to such country
cease using the Trademark and any such logos, slogans, and marketing rights of
Biomatrix or any imitations thereof and (ii) immediately execute and deliver to
Biomatrix any documents or instruments reasonably requested by Biomatrix to give
full effect to the provisions of this Section 2.2.

         2.3 Royalty. In consideration of the license granted to Wyeth in
Section 2.1, Wyeth agrees to pay royalties to Biomatrix as follows:

             (a) Wyeth shall pay to Biomatrix royalties in an amount equal to

                                        *

                                       *

             (b) The amount of royalties due hereunder shall be computed
     quarterly. Within

                                       *

             after the close of each calendar quarter, Wyeth shall pay to
     Biomatrix in cash the royalties owed hereunder with respect to such
     quarter. Each such payment shall be accompanied by a statement describing
     in reasonable detail the calculation of the amount of the accompanying
     royalty payment.

                                       *

             (c) All royalty payments shall be made in U.S. Dollars. The amount
     of Net Revenues paid in another currency shall be converted into U.S.
     Dollars in accordance with Section 4 of the International License
     Agreement.

             2.4. Intangibles. Biomatrix shall have exclusive ownership rights
to the Trademark and all other product specific logos, slogans and other
intangibles relating to the Products and Extended Products possessed or
controlled by Wyeth or any of its Affiliates.


             3. TERM AND TERMINATION. Unless earlier terminated pursuant to this
Paragraph 3, this Agreement shall continue in force, on a country-by-country
basis, as long as Wyeth is selling any Product or Extended Product in such
country in the Territory. Notwithstanding the foregoing, this Agreement may be
terminated by Biomatrix at any time upon written notice thereof to Wyeth upon
the occurrence of any of the following:

                           (a) Breach of any duty or obligation of Wyeth
                  hereunder not cured within thirty (30) days after receipt of
                  written notice thereof from Biomatrix;

                           (b) Termination of each of the International License
                  and U.S. License by Biomatrix as a result of Wyeth's breach;

                           (c) Termination of each of the International License
                  and U.S. License by Wyeth;

                           (d) Institution by Wyeth of bankruptcy, insolvency,
                  liquidation or receivership proceedings, or proceedings for
                  reorganization under bankruptcy or comparable laws;

                           (f) Wyeth's making of a general assignment for the
                  benefit of creditors; and

                           (g) Wyeth's failure to use the Trademark for a
                  material amount of time in connection with material amounts of
                  sales of Products or Extended Products.


                  4. EFFECTS OF TERMINATION.

                  Wyeth shall not have, and hereby waives, any claim for lost
profits or goodwill relating to the termination of this Agreement. Upon the
expiration or termination of this Agreement, Wyeth shall (i) immediately
discontinue all use of the Trademark, its component parts or any colorable
imitations thereof, by itself or in combination with any other words, letter,
symbols or designs and all other logos, slogans, marketing rights and other
intangibles (or any imitations thereof) relating to the Products or Extended
Products and (ii) immediately take all necessary action and execute and deliver
to Biomatrix any documents and instruments reasonably requested by Biomatrix to
give full effect to the provisions of this Section 4, including without
limitation those necessary to remove Wyeth as a registered user and/or a
recorded licensee of the Trademark.

                                        *

Thereafter, Biomatrix shall have the right, but not the obligation,

                                        *

The termination of this Agreement shall not affect any obligation accruing prior
to such termination. In the event that Wyeth fails promptly upon written request
by Biomatrix to comply with any of its agreements in this Section 4, Wyeth
hereby irrevocably consents to Biomatrix's taking any action necessary to give
effect to such agreements.


                  5. QUALITY CONTROL

                  Throughout the term of this Agreement, Wyeth shall maintain
the quality of products manufactured, sold or distributed under the Trademark at
least at the level of quality maintained for products currently sold and
distributed under the Trademark. Any products sold under the Trademark shall be
made strictly to the same specifications as the Product and/or Extended Product
made by Biomatrix under the Supply Agreement between Biomatrix and Wyeth dated
as of February 7, 1997. If any product sold under the Trademark is not
manufactured by Biomatrix, at least

                                        *

prior to use or distribution thereof, Wyeth shall deliver to Biomatrix for
inspection, testing and/or review samples of product to be sold and all new, or
changes to existing, product signs, labels, packaging materials, advertising and
other materials bearing the Trademark; and Wyeth shall not offer for sale, sell,
distribute or use any such new or changed product or materials without
Biomatrix's express prior written approval. Biomatrix' approval

                                        *

In order to determine Wyeth's compliance with this Paragraph 5, Biomatrix or its
authorized representative may inspect and/or test, at reasonable times and


         *Confidential portions have been omitted and filed separately with the
Commission.
<PAGE>   5
                                      -5-




under reasonable circumstances, all uses of the Trademark by Wyeth and all
underlying goods. Each product produced or distributed hereunder shall comply
with all applicable laws and regulations and shall conform in all respects to
the sample of such product approved by Biomatrix hereunder. In the event of any
nonconformity or any deterioration in the quality of a product sold under the
Trademark (as determined by Biomatrix in good faith), Biomatrix may, in addition
to other available remedies, by written notice to Wyeth, require that such
product be immediately withdrawn from the market and Wyeth shall promptly cause
such withdrawal.


                  6. INTELLECTUAL PROPERTY

                  6.1 Use and Display of the Trademarks. Wyeth shall use and
display the Trademark in a conspicuous manner in connection with all Products
and Extended Products. Without limiting the generality of the foregoing:

                           (a) Wyeth shall include in all advertising and
         promotional material created by or for Wyeth in which the Trademark
         appears such legends, markings, and notices (such as "TM" or "(R)"
         superscript, as appropriate) as required or permitted by any foreign,
         federal, state or local law or regulations.

                           (b) Subject to applicable laws and regulations in the
         Territory, Wyeth shall ensure that all trade literature, publications
         and promotional materials relating to any product sold under the
         Trademark shall specify the concept of viscosupplementation and that
         such concept has been conceived and introduced by Biomatrix.

                           (c) Wyeth shall not use the Trademark or any marks
         confusingly similar thereto (i) in connection with any goods or
         services other than products made to the specifications for the
         Products or Extended Products or (ii) as part of or in connection with
         the legal name of any Person or the tradename of any Person;

                           (d) Wyeth shall not have the right to use any
         variation of the Trademark without Biomatrix's written approval (which
         approval shall be in Biomatrix's sole discretion) and, in the event
         that Biomatrix approves the use of any variation of a Trademark, such
         approved variation shall become a Trademark owned by Biomatrix and
         governed by the terms of this Agreement;

                           (e) Wyeth shall not use the Trademark with any other
         trademark or tradename, other than Wyeth's standard "house mark,"
         without Biomatrix's prior written approval (which approval shall not be
         unreasonably withheld).

                  6.2 Ownership and Maintenance of Trademark. Biomatrix
expressly reserves the sole and exclusive ownership of the Trademark and all
rights relating thereto. Wyeth hereby acknowledges that Biomatrix is the sole
and exclusive owner of the
<PAGE>   6
                                      -6-




Trademark. Wyeth shall not question or otherwise challenge, either directly or
indirectly, during the term of this Agreement or after its termination or
expiration, Biomatrix's ownership of, and rights in, the Trademark and the
goodwill associated therewith or the validity of this Agreement. All use of the
Trademark by Wyeth shall inure to the benefit of Biomatrix. Upon Biomatrix's
request, whether during or after the term of this Agreement, Wyeth shall provide
necessary samples and information to permit Biomatrix to effect trademark or
service mark registrations and execute and deliver to Biomatrix any documents
required by Biomatrix to confirm Biomatrix's ownership of the Trademark. Wyeth
shall not at any time, either during or after the term of this Agreement, apply
to register the Trademark, or any mark confusingly similar thereto, as a
trademark or service mark anywhere in the world. The parties shall execute a
short form Trademark license agreement to the extent that it is necessary to
record the Trademark license hereunder in any country in the Territory where
Biomatrix deems such recordation to be necessary or desirable.

                  6.3 No Assignment. It is understood and agreed that nothing in
this Agreement will be deemed in any way to constitute an assignment by
Biomatrix of the Trademark or of the goodwill associated therewith, or to give
Wyeth any right, title, or interest in and to the Trademark or the goodwill
associated therewith (except the right to make use thereof as herein provided).

                  6.4 Infringements by Third Parties. Wyeth shall notify
Biomatrix promptly of any use by any Person of the Trademark or a mark similar
to the Trademark. Biomatrix in its sole discretion shall decide whether or how
to proceed against a third party infringer. Wyeth shall cooperate fully with
Biomatrix in connection with the prosecution of any claim against any such third
party infringer. If requested by Biomatrix, Wyeth shall join with Biomatrix, at
Biomatrix's expense, in any such action as Biomatrix in its sole discretion may
deem advisable, provided, however, that Wyeth shall have no right to take any
action with respect to the Trademark without Biomatrix's prior written approval,
which approval may be withheld in Biomatrix's sole discretion. The proceeds of
any settlement of, or recovery from, any such action shall belong entirely to
Biomatrix. If Biomatrix declines in writing to bring any action against an
alleged third party infringer, Wyeth may proceed and will bear all expenses of
the action. If necessary for Wyeth to proceed, Biomatrix shall join with Wyeth,
at Wyeth's expense. The proceeds of any settlement of, or recovery from, any
such action initiated by Wyeth shall belong entirely to Wyeth.

                  7. INDEMNIFICATION

                  7.1 Indemnification by Biomatrix. Biomatrix agrees to defend,
indemnify and hold harmless Wyeth from and against any and all claims of third
parties and liabilities, judgments, penalties, losses, costs, damages and
expenses resulting therefrom, arising from infringement claims by third parties
by reason of Wyeth's lawful use of the Trademark in accordance with this
Agreement. In the event of any such claim, upon written request by Biomatrix,
Wyeth shall immediately cease and desist from any and all further use or display
of the Trademark.

                  7.2 Indemnification by Wyeth. Wyeth agrees to defend,
indemnify and hold harmless Biomatrix from and against any and all claims of
third parties and liabilities, judgments, penalties, losses, costs, damages and
expenses resulting therefrom, arising by reason of  *  by Wyeth, its agents, 
employees or representatives.

         7.3 Procedures for Indemnification. With respect to any claims falling
within the scope of the foregoing indemnifications:


                           (a) Each party agrees to notify the other promptly
         and in writing of such claims, and to keep the other fully advised with
         respect to such claims and the progress of any legal actions relating
         thereto in which the other party is not a participant.

                           (b) Biomatrix shall have the sole right to undertake
         and control the defense and settlement of any claims relating to the
         ownership or validity of the Trademark or of any pending application or
         registration of the Trademark. Wyeth shall cooperate fully with
         Biomatrix in connection with the defense of any such claims brought by
         third parties. If requested by Biomatrix, Wyeth shall join with
         Biomatrix, at Biomatrix's expense, in any such action as Biomatrix in
         its sole discretion shall deem advisable.

                           (c) Wyeth shall have the right to participate at its
         own expense in the defense of any claim instituted against it, and, if
         it does so participate, it shall not have the right to recover against
         Biomatrix the costs and expenses (including its attorneys' fees) of its
         participation in such suit.

                           (d) In the event that a party assumes the defense of
         a claim against the other party, the party assuming the defense shall
         not enter into any compromise or settlement of the claim without the
         prior written consent of the other party, which consent shall not be
         unreasonably withheld.

                  8.        MISCELLANEOUS PROVISIONS

                8.1 Assignment. The rights and obligations of the parties hereto
shall inure to the benefit of and shall be binding upon the authorized
successors and permitted assigns of each party. Neither party may, without the
prior written consent of the other party, take any of the following actions
(collectively referred to herein as an "Assignment"): (i) assign or transfer its
rights or obligations under this Agreement, (ii) license or sublicense any of
its rights or obligations under this Agreement, or (iii) designate another
person to perform all or part of its obligations under this Agreement or have
all or part of its rights and benefits under this Agreement; provided, however,
that a party may make Assignments to Affiliates of such party or to a successor,
by merger, and provided, further that in the case of an Assignment to an
Affiliate the assigning party shall promptly notify the other party in writing
of such

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

                                      -8-


Assignment and shall remain liable (both directly and as guarantor) with respect
to all obligations so assigned. In the event of any permitted Assignment or in
the event that an Affiliate of either party shall exercise rights and/or perform
obligations hereunder pursuant to the terms of this Agreement, the assignee or
Affiliate, as the case may be, shall specifically assume and be bound by the
provisions of the Agreement by executing and agreeing to an assumption agreement
satisfactory to the other party hereto.

                  8.2 Governing Law; Specific Performance. (a) This Agreement
and the respective rights and obligations of the parties shall be governed by
and construed in accordance with the internal and substantive laws of the State
of New Jersey, United States of America (without regard to principles of
conflicts of laws). The parties hereby agree that the United Nations Convention
on Contracts for the International Sale of Goods shall not apply to this
Agreement or any other document contemplated hereby. In the event of any dispute
touching or concerning this Agreement, the parties hereby agree to submit such
dispute to their respective chief executive officers or their designees by
notice delivered in accordance with the provisions of Section 8.6 hereof. Each
of the parties agrees that any suit relating to this Agreement may be brought in
the courts of the State of New Jersey or any federal court and service of
process in any such suit being made by mail at the address specified in Section
8.6. Each party hereby waives any objection that it may now or hereafter have to
the venue of any such suit or any such court or that such suit is brought in an
inconvenient court.

         (b) Injunctive Relief. Each of the parties hereto acknowledges and
agrees that damages will not be an adequate remedy for any material breach or
violation of this Agreement if such material breach or violation would cause
immediate and irreparable harm (an "Irreparable Breach"). Accordingly, in the
event of a threatened or ongoing Irreparable Breach, each party hereto shall be
entitled to seek, in any state or federal court in the State of New Jersey,
equitable relief of a kind appropriate in light of the nature of the ongoing
threatened Irreparable Breach, which relief may include, without limitation,
specific performance or injunctive relief; provided, however, that if the party
bringing such action is unsuccessful in obtaining the relief sought, the moving
party shall pay the non-moving party's reasonable costs, including attorney's
fees, incurred in connection with defending such action. Such remedies shall not
be the parties' exclusive remedies, but shall be in addition to all other
remedies provided in this Agreement.

Exhibits are to sections and Exhibits to this Agreement. The title of this

condition of this Agreement is declared to be invalid, void or unenforceable,
the remainder of the provisions shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

                  8.5 Waiver. The failure of either party to require the
performance of any provision of this Agreement by the other party shall not be
deemed a waiver and shall not deprive the party of its full right to require
such performance in the particular instance or at any other time.
Any waiver must be in writing executed by the waiving party.

amended except by writing which refers specifically to this Agreement signed on

                  8.10 Other Documents The parties agree to implement this
Agreement by executing or causing to be executed such additional documents and
agreements as may be necessary to fully protect the Trademark and effectively
carry out the terms of this Agreement in accordance with applicable laws and
regulations.

for the exemption, the parties hereto agree that they will, as soon as it is
