                  Net Sales of each Product. Such royalty shall be paid with
                  respect to each country of the world from the date of the
                  first commercial sale by Pfizer or any sublicensee of Pfizer
                  of such Product in each such country until the expiration of
                  the last ATRIX Patent Rights and Pfizer Patent Rights to
                  expire with respect to each such country and each such
                  Product.

         4.2.     ROYALTY RATES.

                  4.2.1.   Pfizer shall pay ATRIX a royalty for the sale of each
                           Product; [**]

                  in which such Net Sales are made. Such payments shall be
                  accompanied by a statement showing the Net Sales of each
                  Product by Pfizer or any sublicensee of Pfizer in each
                  country, the applicable royalty rate for such Product, and a

<PAGE>   8

         4.4.     ACCOUNTING. The Net Sales used for computing the royalties
                  payable to ATRIX by Pfizer shall be computed and paid in US
                  dollars by wire transfer in immediately available funds to a
                  U.S. account designated by ATRIX, or by other mutually
                  acceptable means. For purposes of determining the amount of
                  royalties due, the amount of Net Sales in any foreign currency
                  shall be computed by (a) converting such amount into U.S.
                  dollars at the prevailing commercial rate of exchange for
                  purchasing dollars with such foreign currency as published in
                  the Wall Street Journal for the close of the last business day
                  of the calendar quarter for which the relevant royalty payment
                  is to be made by Pfizer and (b) deducting the amount of any
                  governmental tax, duty, charge, or other fee actually paid in
                  respect of such conversion into, and remittance of U.S.
                  dollars.

         4.5.     RECORDS. Pfizer shall keep for three (3) years from the date
                  of each payment of royalties complete and accurate records of
                  sales by Pfizer of each Product in sufficient detail to allow
                  the accruing royalties to be determined accurately. ATRIX
                  shall have the right for a period of three (3) years after
                  receiving any report or statement with respect to royalties
                  due and payable to appoint at its expense an independent
                  certified public accountant reasonably acceptable to Pfizer to
                  inspect the relevant records of Pfizer to verify such report
                  or statement. Pfizer shall make its records available for
                  inspection by such independent certified public accountant
                  during regular business hours at such place or places where
                  such records are customarily kept, upon reasonable notice from
                  ATRIX, to verify the accuracy of the reports and payments.
                  Such inspection right shall not be exercised more than once in
                  any calendar year nor more than once with



                                       8
<PAGE>   9

                  respect to sales in any given period. If such accounting firm
                  concludes that such payments were underpaid, Pfizer shall pay
                  ATRIX the amount of any such underpayments within thirty (30)
                  days of the date ATRIX delivers to Pfizer such accounting
                  firm's written report. ATRIX agrees to hold in strict
                  confidence all information concerning royalty payments and
                  reports, and all information learned in the course of any
                  audit or inspection, except to the extent necessary for ATRIX
                  to reveal such information in order to enforce its rights
                  under this Agreement or if disclosure is required by law. The
                  failure of ATRIX to request verification of any report or
                  statement during said three-year period shall be considered
                  acceptance of the accuracy of such report, and Pfizer shall
                  have no obligation to maintain records pertaining to such
                  report or statement beyond said three-year period. The results
                  of each inspection, if any, shall be binding on both parties.

         4.6.     MILESTONE PAYMENTS. Pfizer shall pay ATRIX, within thirty (30)
                  days of the completion of each event set forth below
                  ("Event"), the payment listed opposite that Event. Payments
                  shall be made in US dollars by wire transfer in immediately
                  available funds to a U.S. bank account designated by ATRIX, or
                  other mutually acceptable means. Pfizer shall be obligated to
                  make each payment only once with respect to each Product
                  affected by an Event.

5.       LEGAL ACTION.

         5.1.     ACTUAL OR THREATENED DISCLOSURE OR INFRINGEMENT. When
                  information comes to the attention of Pfizer to the effect
                  that any ATRIX Patent Rights or Pfizer Patent Rights claiming
                  a Product have been or are threatened to be unlawfully
                  infringed, Pfizer shall have the right at its expense to take
                  such action as it may deem necessary to prosecute or prevent
                  such unlawful infringement, including the right to bring or
                  defend any suit, action or proceeding involving any such
                  infringement; provided, however, that Pfizer shall not settle
                  any claim or proceeding which involves or relates to the
                  infringement of any ATRIX Patent Rights without ATRIX's prior
                  written consent. Pfizer shall notify ATRIX promptly of the
                  receipt of any such information and of the commencement of any
                  such suit, action or proceeding. If Pfizer determines that it
                  is necessary or desirable for ATRIX to join any such suit,
                  action or proceeding, ATRIX shall, at Pfizer's expense,
                  execute all papers and perform such other acts as may be
                  reasonably required to permit Pfizer to commence such action,
                  suit or proceeding in which case Pfizer shall hold ATRIX free,
                  clear and harmless from any and all costs and expenses of
                  litigation, including attorneys fees. If Pfizer brings a suit,
                  it shall have the right first to reimburse itself out of any
                  sums recovered in such suit or in its settlement for all costs
                  and expenses, including attorney's fees, related to such suit
                  or settlement, and [ ** ] of any funds that shall remain from
                  said recovery shall be paid to ATRIX and the balance of such
                  funds shall be retained by Pfizer. If Pfizer does not, within
                  one hundred twenty (120) days after giving notice to ATRIX of
                  the above-described information, notify ATRIX of Pfizer's
                  intent to bring suit against any infringer, ATRIX shall have
                  the right to bring suit



                                       10
<PAGE>   11

                  for such alleged infringement, but it shall not be obligated
                  to do so, and may join Pfizer as party plaintiff, if
                  appropriate, in which event ATRIX shall hold Pfizer free,
                  clear and harmless from any and all costs and expenses of such
                  litigation, including attorney's fees, and any sums recovered
                  in any such suit or in its settlement shall belong to ATRIX.
                  However, [ ** ] of any such sums received by ATRIX, after
                  deduction of all costs and expenses related to such suit or
                  settlement, including attorney's fees paid, shall be paid to
                  Pfizer. Each Party shall always have the right to be
                  represented by counsel of its own selection and at its own
                  expense in any suit instituted by the other for infringement
                  under the terms of this Section. If Pfizer lacks standing and
                  ATRIX has standing to bring any such suit, action or
                  proceeding, then ATRIX shall do so at the request of Pfizer
                  and at Pfizer's expense.

         5.2.     DEFENSE OF INFRINGEMENT CLAIMS. ATRIX will cooperate with
                  Pfizer at Pfizer's expense in the defense of any suit, action
                  or proceeding against Pfizer or any sublicensee of Pfizer
                  alleging the infringement of the intellectual property rights
                  of a third party by reason of the use of ATRIX Patent Rights
                  and Pfizer Patent Rights in the manufacture, use, sale, offer
                  for sale, or import of the Product. Pfizer shall give ATRIX
                  prompt written notice of the commencement of any such suit,
                  action or proceeding or claim of infringement and will furnish
                  ATRIX a copy of each communication relating to the alleged
                  infringement. ATRIX shall give to Pfizer all authority
                  (including the right to exclusive control of the defense of
                  any such suit, action or proceeding and the exclusive right
                  after consultation with ATRIX, to compromise, litigate, settle
                  or otherwise dispose of any such suit, action or proceeding),
                  at Pfizer's expense,



                                       11
<PAGE>   12

                  including by providing information and assistance necessary to
                  defend or settle any such suit, action or proceeding;
                  provided, however, Pfizer shall obtain ATRIX's prior written
                  consent to such part of any settlement which contemplates
                  payment or other action by ATRIX or has a material adverse
                  effect on ATRIX's business (which material adverse effect
                  shall include, but not be limited to, an admission in
                  connection with such settlement by ATRIX of any issue, fact,
                  allegation or any other aspect of the claim being settled). If
                  the Parties agree that ATRIX should institute or join any
                  suit, action or proceeding pursuant to this Section, Pfizer
                  may, at Pfizer's expense, join ATRIX as a defendant if
                  necessary or desirable, and ATRIX shall execute all documents
                  and take all other actions, including giving testimony, which
                  may reasonably be required in connection with the prosecution
                  of such suit, action or proceeding.

         5.3.     HOLD HARMLESS. ATRIX agrees to defend, protect, indemnify and
                  hold harmless Pfizer and any sublicensee of Pfizer, from and
                  against any loss or expense arising from any proven claim of a
                  third party that it has been granted rights by ATRIX that
                  Pfizer or any sublicensee of Pfizer in exercising their rights
                  granted to Pfizer by ATRIX pursuant to this Agreement, has
                  infringed upon such rights granted to such third party by
                  ATRIX.

         5.4.     THIRD PARTY LICENSES. [ ** ]

6.       REPRESENTATION AND WARRANTY. ATRIX represents and warrants to Pfizer
         that it has the right to grant the License granted pursuant to this
         Agreement, and that the License so granted does not conflict with or
         violate the terms of any agreement between ATRIX and any third party.

7.       OTHER AGREEMENTS. Concurrently with the execution of this Agreement,
         ATRIX and Pfizer shall enter into a Research Agreement and a Stock
         Purchase Agreement. This Agreement, the Research Agreement, and the
         Stock Purchase Agreement are the sole agreements with respect to the
         subject matter and supersede all other agreements and understanding
         between the parties with respect to same.

8.       TERMINATION AND DISENGAGEMENT.

         8.1      EVENTS OF TERMINATION. The following events shall constitute
                  events of termination ("Events of Termination"):

                  8.1.1    Any written representation or warranty by ATRIX or
                           Pfizer, or any of its officers, made under or in
                           connection with this Agreement shall prove to have
                           been incorrect in any material respect when made;

                  8.1.2    ATRIX or Pfizer shall fail in any material respect to
                           perform or observe any term, covenant or
                           understanding contained in this Agreement or in any
                           of the other documents or instruments delivered
                           pursuant to, or concurrently with, this Agreement,
                           and any such failure shall remain unremedied for
                           thirty (30) days after written notice to the failing
                           party.

         8.1.     Upon the occurrence of any Event of Termination, the Party not
                  responsible may, by notice to the other Party, terminate this
                  Agreement.

         8.2.     Termination of this Agreement by either Party, with or without
                  cause, will not terminate the licenses granted pursuant to
                  Section 5.2 of the Research Agreement.

         8.3.     Termination of this Agreement for any reason shall be without
                  prejudice to:

                  a.       the rights and obligations of the Parties provided in
                           Sections 6, 7, and 9;



                                       14
<PAGE>   15

                  b.       ATRIX's right to receive all royalty payments accrued
                           hereunder; or

                  c.       any other remedies which either Party may otherwise
                           have.

         8.4.     At any time or times Pfizer may terminate, at its sole
                  discretion, this Agreement with respect to any Product in any
                  country or countries in the world upon thirty (30) days prior
                  notice to ATRIX. Upon such termination by Pfizer, all
                  licenses, other than the licenses granted under Section 5.2 of
                  the Research Agreement shall terminate with respect to such
                  country or countries for any such Product.

         8.5.     Expiration or termination of this Agreement shall not relieve
                  the Parties of any obligation accruing prior to such
                  expiration or termination. Except as set forth below or
                  elsewhere in this Agreement, the obligations and rights of the
                  Parties under Sections 4, 5, 9, 10 and 11 shall survive
                  expiration or termination of this Agreement.

         8.6.     Within thirty (30) days following the expiration or
                  termination of this Agreement, each Party shall return to the
                  other Party, or destroy, upon the written request of the other
                  Party, any and all Confidential Information of the other Party
                  in its possession and upon a Party's request, such destruction
                  (or delivery) shall be confirmed in writing to such Party by a
                  responsible officer of the other Party. Notwithstanding the
                  provisions of this Section 8.6, either Party may retain one
                  (1) copy of such Confidential Information for the sole purpose
                  of determining its continuing confidentiality obligation to
                  the other Party under this Agreement.

9.       INDEMNIFICATION. Pfizer and ATRIX will indemnify each other for
         damages, settlements, costs, legal fees and other expenses incurred in
         connection with a claim by a third party against either Party based on
         any action or omission of the indemnifying Party's agents, employees,
         or officers related to its obligations under this Agreement; provided,
         however, that the foregoing shall not apply (a) if the claim is found
         to be based upon the negligence, recklessness or wilful misconduct of
         the Party seeking indemnification; or (b) if such Party fails to give
         the other Party prompt notice of any claim it receives and such failure
         materially prejudices the other Party with respect to any claim or
         action to which its obligation pursuant to this Section applies.
         Notwithstanding the foregoing, ATRIX shall not indemnify Pfizer for
         claims arising from the sale of Products or exercise of rights granted
         to Pfizer under Section 5.2 of the Research Agreement, or the License
         Agreement (including without limitation product liability claims) and
         Pfizer shall indemnify ATRIX with respect to such claims and to claims
         arising from Pfizer Patent Rights, except for intellectual property
         claims with respect to ATRIX Patent Rights. Each Party, in its sole
         discretion, shall choose legal counsel, shall control the defense of
         such claim or action and shall have the right to settle same on such
         terms and conditions it deems advisable; provided however, it shall
         obtain the other Party's prior consent to such part of any settlement
         which requires payment or other action by the other Party or is likely
         to have a material adverse effect on the other Party or the other
         Party's business.

10.      NOTICES AND REPORTS.

         10.1.    All notices shall be in writing mailed via certified mail,

         11.4     COUNTERPARTS. This Agreement may be executed simultaneously in
                  two or more counterparts, each of which shall be deemed an

                  or, in the case of waiver, by the Party or Parties waiving
                  compliance. The delay or failure of any Party at any time or
                  times to require performance of any provisions shall in no
                  manner affect the rights at a later time to enforce the same.

         11.6     NO THIRD PARTY BENEFICIARIES. No third party including any
                  employee of any Party to this Agreement shall have or acquire
                  any rights by reason of this Agreement. Nothing contained in
                  this Agreement shall be deemed to constitute the Parties

                  relationship between the two Parties shall not constitute a
                  partnership or agency of any kind. Neither ATRIX nor Pfizer
                  shall have the authority to make any statements,

                  or in part, to any of its Affiliates, any purchaser of all or
                  substantially all of its assets or to any successor

                  Party with or into such corporations.

         11.9     FORCE MAJEURE. Neither Pfizer nor ATRIX shall be liable for
                  failure of or delay in performing obligations set forth in
                  this Agreement, and neither shall be deemed in breach of its
                  obligations, if such failure or delay is due to natural
                  disasters or any causes reasonably beyond the control of
                  Pfizer or ATRIX; provided that the Party whose performance is
                  delayed or prevented shall continue to use good faith diligent
                  efforts to mitigate, avoid or end such delay or failure in
