     (B) verifying the calculation of the Net Selling Price, the calculation of

     shall be conducted during MediGene's normal business hours, no more than
     once in any twelve (12) month period and upon at least ten (10) days prior
     written notice by Atrix to MediGene. If such accounting firm concludes that
     such payments were underpaid for the preceding year, MediGene shall pay
     Atrix the amount of any such underpayments for the preceding year, plus
     interest at a rate equal to the Prime Rate of Interest, within thirty (30)
     days of the date Atrix delivers to MediGene such accounting firm's report
     so concluding that such payments were underpaid for the preceding year. If
     such accounting firm concludes that such payments were overpaid for the
     preceding year, Atrix shall pay to MediGene the amount of any such
     overpayments for the preceding year, without interest, within thirty (30)
     days of the date Atrix delivers to MediGene such accounting firm's report
     so concluding that such payments were overpaid for the preceding year.
     Atrix shall bear the full cost of such audit unless such audit discloses an
     underpayment by more than five percent (5%) of the amount due for the
     preceding year. In such case, MediGene shall bear the full cost of such
     audit.

          (e) Taxes. All taxes levied on account of the payments accruing to
     Atrix under this Agreement shall be paid by Atrix for its own account,
     including taxes levied thereon as income to Atrix. If provision is made in
     law or regulation for withholding, such tax shall be deducted from the
     payment made by MediGene, paid to the proper taxing authority and a receipt
     of payment of the tax secured and promptly delivered to Atrix. Each Party
     agrees to assist the other Party in claiming exemption from such deductions
     or withholdings under any double taxation or similar agreement or treaty
     from time to time in force.

          (f) Prohibited Payments. Notwithstanding any other provision of this
     Agreement, if MediGene is prevented from paying any payments by virtue of
     the statutes,


                                       15



     laws, codes or governmental regulations of the country from which the
     payment is to be made, then such payment may be paid by depositing funds in
     the currency in which it accrued to Atrix's account in a bank acceptable to
     Atrix in the country whose currency is involved.

                                   NEW PRODUCT

     Section 5.01. NEW PRODUCT. Subject to MediGene's right of first negotiation
under Section 5.02 below, Atrix may or, at MediGene's request and at [**] will,
seek to develop and have the EMEA or other Competent Authority approve a New
Product.

     Section 5.02. RIGHT OF FIRST NEGOTIATION. For a period of thirty (30) days
following the receipt of notice from (i) Atrix of its intention to develop a New
Product or (ii) MediGene of its intention to have Atrix develop a New Product,
MediGene shall have the first right to negotiate binding material terms for a
definitive license agreement for the New Product. In the event (a) MediGene does
not determine within such thirty (30) day period to pursue a license for the New
Product, (b) the Parties are unable to reach agreement on binding material terms
of such a license within such thirty (30) day period, or (c) if the Parties have
reached agreement on binding material terms of such a license within such thirty
(30) day period, but are unable to enter into a definitive agreement within
ninety (90) days following the written notice from Atrix, which period may be
extended upon the mutual agreement of the Parties, Atrix shall have no further
obligation to MediGene under this Section 5.02. If MediGene and Atrix cannot
agree to the terms of such license, then Atrix may enter into an agreement with
a Third Party, provided that the terms of the agreement are no less favorable to
Atrix, in any material respect (individually or in the aggregate), than those
last proposed in writing by MediGene. The rights of MediGene under this Section
5.02 shall be limited to those countries in the Territory for which MediGene
retains a license under Sections 3.02 and 3.03 as of the date written notice is
received under this Section 5.02 by Atrix or MediGene, as applicable. If Atrix
enters into an agreement with a Third Party under this Section 5.02, Atrix shall
notify MediGene of this fact within four (4) weeks after the date the agreement
is entered into. MediGene shall then have the right to appoint an appropriate
independent person, reasonably acceptable to Atrix, having sufficient experience
in licensing matters, which person shall execute a confidentiality agreement in
such form as is reasonably satisfactory to Atrix, to examine the terms and
conditions of such agreement to determine that the terms thereof are no less
favorable to Atrix, in any material respect (individually or in the aggregate),
than those last proposed in writing by MediGene. Such determination shall be
made within six (6) weeks after the date Atrix provides notice to MediGene that
it has entered into such an agreement with a Third Party.

                                   ARTICLE VI

                                COMMERCIALIZATION

     Section 6.01. PROMOTION AND MARKETING OBLIGATIONS.

          (a) Marketing Efforts. MediGene agrees to use commercially reasonable
     efforts to promote the sale, marketing and distribution of the Product in
     the Territory, consistent with accepted business practices devoting the
     same level of efforts as it devotes to its own products of comparable
     market potential. "Comparable market potential" shall be fairly determined
     by MediGene in good faith and shall be based upon market size, price,
     competition and general marketing parameters. Each Party shall promptly
     advise the other Party of any issues that materially and adversely affect
     its ability to market the Product in the Territory. In such event, senior
     executives of MediGene and Atrix shall meet and in good faith discuss what
     actions should be taken in light of such issues.

          (b) Trademarks. Subject to the terms and conditions of this Agreement,
     MediGene shall have the right to use any trademark, logo, design and/or
     tradedress for the Product in the Territory, provided such trademark, logo,
     design and/or tradedress complies with Applicable Laws.

          (c) Packaging. Atrix shall package and label the Product, the Units
     and the Demonstration Samples in compliance with the Packaging
     Specifications and Applicable Laws. Atrix, in consultation with MediGene,
     shall be responsible for assuring that such packaging and labeling conform
     with all Applicable Laws, if any, of the FDA for export of the Product and
     the Demonstration Samples into the Territory and that the Units comply with
     the Packaging Specifications. Atrix, in consultation with MediGene, shall
     also be responsible for assuring that packaging and labeling comply with
     all Applicable Laws where such Product is to be distributed for sale in the
     Territory. All additional incremental costs resulting from changes to the
     Packaging Specifications made at the request of MediGene that are not
     required to export or import the Product to countries in the Territory on a
     country by country basis under Applicable Laws shall be borne by MediGene.

          (d) Marketing Plans And Reports. Sixty (60) days prior to the expected
     date of First Commercial Sale in any Major Country and at the beginning of
     each calendar year thereafter, MediGene shall submit to the Advisory Board
     in writing the annual marketing, sales and distribution plan for each Major
     Country detailing MediGene's and its Affiliates' proposed marketing, sales
     and distribution strategy and tactics for the sale and distribution of
     Product during such calendar year, or portion thereof, including the
     expected selling price schedules for each Product in each Major Country
     (including any (i) prompt payment or other trade or quantity discounts
     which MediGene expects to offer and (ii) commission rates or rebates which
     MediGene expects to offer to distributors and agents). In addition, upon
     the request of Atrix, MediGene shall submit to the Advisory Board copies of
     any market research reports relating to Product sales and Product
     competition which MediGene or its Affiliates commission or otherwise obtain
     to the extent permissible by the agency preparing the report. To the extent
     the foregoing


                                       17



     information is contained in plans or reports which contain information
     about other products or markets, MediGene may submit to the Advisory Board
     only those excerpts from such plans or reports which relate to the Product
     and Product competition.

          (e) Advisory Board.

               (i) Formation and Function. Promptly after the Effective Date,
          MediGene and Atrix will each appoint two (2) senior representatives to
          a committee (the "Advisory Board") that shall have oversight for any
          activity under this Agreement for the Territory. Atrix will select an
          individual to serve as chairman of the Advisory Board for the initial
          twelve (12) months. Thereafter, the chairmanship will rotate between a
          MediGene member and an Atrix member every twelve (12) months. Except
          as set forth in Section 13.01, the Advisory Board will be consulted by
          both Parties on all major decisions in the development and marketing
          of the Product in each country in the Territory, including, without
          limitation, in the following areas as they relate to the Product:

                    (A) Product positioning in the marketplace;

                    (B) quantity of direct selling efforts, including the number
               of sales details to be made;

                    (C) extent and degree of non-personal selling and
               promotional efforts;

                    (D) quantity and content of workshops and medical symposia;

                    (E) design and implementation of a Phase IV clinical study
               program to support the Product;

                    (F) design and implementation of a consumer awareness
               program;

                    (G) selection of physicians for a medical advisory board and
               speakers bureau;

                    (H) planning for international regulatory submissions;

                    (I) dispute resolution regarding sales, marketing and
               promotional activities related to the Product; and

                    (J) internet presence;

                    (K) design and performance of other clinical studies in any
               country of the Territory.

          MediGene, alone, will be responsible for making the final decisions on
          the development and marketing of the Product (subject to the
          provisions of Section 2.02) regardless of the action or inaction of
          the Advisory Board. MediGene


                                       18



          agrees that in making such decisions and taking such actions that it
          will consider the effect of such decisions and actions on the
          marketing and sale of the Product outside the Territory.
          Notwithstanding the foregoing, for the avoidance of doubt, Atrix,
          alone, shall make the final decision on all matters concerning the
          Manufacture of the Product, except (a) Product labeling, as provided
          in Section 8.03, and (b) if MediGene exercises its Manufacturing
          rights, as provided in Sections 7.06 or 8.02(b).

               (ii) Meetings. The Advisory Board will meet every six (6) months
          and at such other times as a Party may request, alternating between
          Planegg/Martinsried, Germany and Fort Collins, Colorado and will
          otherwise communicate regularly by telephone, facsimile and/or video
          conference. The chairman of the Advisory Board shall prepare minutes
          of all meetings. Each Party recognizes the importance of the Advisory
          Board in the success of the Collaboration and will use diligent
          efforts to cause all of its representatives on the Advisory Board to
          attend all meetings of the Advisory Board. A Party may change any of
          its appointments to the Advisory Board at any time upon giving written
          notice to the other Party.

               (iii) Working Groups. The Advisory Board may establish
          appropriate working groups for the marketing and any other activities
          necessary for the development and marketing of the Product in the
          Territory. Each working group shall meet at least once every three (3)
          months and at such other times as a Party may request, alternating
          between Planegg/Martinsried, Germany and Fort Collins, Colorado and
          will otherwise communicate regularly by telephone, facsimile and/or
          video conference. All actions of a working group shall be by unanimous
          consent of its members and be reported to the Advisory Board in
          writing for approval by the Advisory Board. Any disputes or
          disagreements within a working group shall be resolved by the Advisory
          Board.

          (f) Co-Promotional Activities of Atrix. Beginning [**] following the
     launch of the first of any Product on a country-by-country basis within the
     Territory, Atrix shall have the right, [**] to participate in the sales,
     marketing and promotion of the Product. If Atrix so elects, [**] and
     MediGene will take all actions, including making any required filings with
     Competent Authorities, necessary to allow Atrix to use the applicable
     Marketing Authorizations in connection with Atrix's participation in such
     activities, as far as legally permissible. [**] Difficulties and
     differences arising from the co-promotional activities of Atrix, in
     particular the Atrix Sales Force, will be discussed within the Advisory
     Board. If these differences cannot be settled by the Advisory Board,
     MediGene is entitled to request that the Atrix Sales Force or individual
     members thereof are withdrawn.

                                   ARTICLE VII

                             MANUFACTURE AND SUPPLY

     Section 7.01. AGREEMENT TO SUPPLY PRODUCT. Subject to the terms hereof,
MediGene agrees to purchase exclusively from Atrix, and Atrix agrees to
Manufacture for, and sell exclusively to MediGene during the Term of this
Agreement, MediGene's total requirements for the Product and the Demonstration
Samples in the Territory on the terms and conditions set forth herein. Subject
to MediGene's prior written approval, such approval not to be unreasonably
withheld, conditioned or delayed by MediGene, Atrix may subcontract any part of
the Manufacturing Process for the Product and the Demonstration Samples to a
Third Party provided: (a) the Product, the Demonstration Samples and the
facilities continue to meet the requirements as defined in this Agreement, (b)
Atrix has obtained all required Governmental Approvals to subcontract any part
of the Manufacturing Process for the Product to be sold in the Territory and (c)
the Third Party has obtained all required Governmental Approvals for the
Manufacturing Process for the Product to be sold in the Territory. If
subcontracting is initiated by Atrix or requested by the Competent Authorities
for any Manufacturing Process for Product to be sold in the Territory, Atrix
will bear the cost of validation and necessary stability work, as well as any
other directly related costs.

     Section 7.02. QUALITY ASSURANCE. Atrix shall Manufacture the Product in
accordance with the Specifications. Atrix shall consult with MediGene as to any
proposed changes in the Specifications, Manufacturing Process, or in Atrix's
quality assurance procedures which might render Atrix unable to supply Product
in accordance with the terms of this Agreement, prior to making those changes,
and obtain MediGene's prior, written consent thereto, which consent will not be
unreasonably withheld, conditioned or delayed by MediGene. Atrix shall
immediately notify MediGene in writing of any changes required by a Competent
Authority in the Specifications or Atrix's quality assurance procedures that
would render Atrix unable to supply the Product and/or Demonstration Samples in
accordance with the terms of this Agreement. The Parties agree to develop and
execute an appropriate action plan in such situation. Any additional costs or
expenses shall be shared between the Parties in such proportion as is equal to
each Party's relative fault in causing such change or changes to occur;
provided, however, that if the Parties cannot reach an agreement in good faith
as to the relative fault of each Party or if neither Party is at fault, such
additional costs and expenses shall be born equally by the Parties.

     Section 7.03. ATRIX'S DUTIES. Atrix covenants to Manufacture the Product in
accordance with the Specifications and Applicable Laws, and to furnish to
MediGene with every Shipment a written certificate of analysis and Certificate
of Compliance that confirms conformity of the Product to the Specifications. The
Product may be subjected to testing by MediGene at its designated facility in
order to verify conformance of the Product with the Specifications. In addition,
Atrix shall:

          (a) provide MediGene with a copy of the written sampling and testing
     procedures used by Atrix to confirm conformity of the Product to the
     Specifications;

          (b) retain a sample of each batch of Product for a period equal to (i)
     five (5) years or (ii) such period as required by Applicable Laws or the
     Competent Authorities. Upon


                                       20



     the written request of MediGene, Atrix shall make such samples available to
     MediGene for inspection. The retained sample shall be sufficient in size to
     allow MediGene and Atrix to perform tests to determine whether or not the
     Product conforms to the Specifications. The retained sample shall be kept
     under the same conditions as those under which the Product is stored at
     MediGene's facilities;

          (c) maintain records to ensure Atrix's ability to perform a complete
     lot history via lot tracing of the Product;

          (d) keep on file all manufacturing records and analytical results
     pertaining to the Manufacture of each batch of Product for a period equal
     to (i) five (5) years or (ii) such period as required by Applicable Laws or
     the Competent Authorities, with such period commencing on the expiration
     date of the last lot of the last batch of Product Manufactured and shipped
     to MediGene. Atrix shall make all such records available to MediGene upon
     request;

          (e) consult on an ongoing basis with the Advisory Board on all aspects
     of the manufacturing and development of the Product, including the use of
     any subcontractors to perform part of the Manufacturing Process and assist
     MediGene on an ongoing basis to obtain all necessary Marketing
     Authorizations, in accordance with Section 2.02;

          (f) provide to MediGene within twenty-four (24) hours of receipt by
     Atrix, complete copies of any and all inspection reports pertaining to the
     Manufacture and development of the Product which Atrix receives from any
     Competent Authority and the FDA, or which is obtained by Atrix from any
     Third Party agency, and promptly provide to MediGene any such report which
     is internally produced by Atrix's staff or that of any of its Affiliates;

          (g) provide MediGene with complete access to all existing and
     hereafter produced: (i) batch records of the Product; (ii) quality
     inspection reports of the Product, whether internally or externally
     generated; (iii) any and all investigation reports of the Product, whether
     internally or externally generated; and (iv) packaging records pertaining
     to the Product; and

          (h) provide MediGene with notice within forty-eight (48) hours of
     notification of any scheduled inspection by any Competent Authority of
     Atrix's facilities, books or records, or of the facilities, books or
     records of any subcontractor being utilized by Atrix to perform any portion
     or all of the Manufacture or development of the Product. Atrix shall inform
     such Competent Authority that MediGene may desire to be present at such
     inspection; provided that MediGene's right to be present is subject to
     approval by such Competent Authority and subject to MediGene being
     available at the time and date established by such Competent Authority.
     Atrix shall use reasonable efforts to secure a time and date for such
     inspection that is reasonably acceptable to MediGene; provided, however,
     that Atrix alone shall have the right to make the final decision on all
     such matters.


                                       21



     Section 7.04. COMPLIANCE WITH APPLICABLE LAWS. MediGene and Atrix (if Atrix
has exercised its co-promotion and/or co-marketing rights pursuant to Sections
6.01(f) and 13.01, respectively, but only in connection with Atrix's activities
thereunder) shall be responsible for compliance with Applicable Laws relating to
the promotion, marketing, sale and distribution of the Product, Units and the
Demonstration Samples, as applicable. Atrix shall be responsible for compliance
with Applicable Laws relating to the Manufacture, design and production of the
Product and the Demonstration Samples, as applicable, and with cGMP relating to
the Manufacture and testing of the Product.

     Section 7.05. SECOND MANUFACTURING SOURCE. Atrix, at its own cost and
expense, shall validate, qualify and obtain all Governmental Approvals for a
Third Party as a second source (the "Second Source") to Manufacture and label
the Product for sale in the Territory. No later than three (3) months after the
Marketing Authorization for each Product is approved, Atrix shall take all
necessary actions and provide all necessary information to enable MediGene to
file a variation to the Marketing Authorization for each Product in the
Territory with the Competent Authorities to request approval by such Competent
Authorities for such Second Source to Manufacture each such Product for sale in
the Territory. After such filing, MediGene, with the assistance of Atrix, shall
use reasonable efforts to obtain final approval by the Competent Authorities for
such Second Source to Manufacture each such Product including modifying the
variation to the Marketing Authorization if required by a Competent Authority.
Upon prior written notice to Atrix, MediGene shall have the right, at its sole
cost and expense, to inspect and audit the Second Source's facilities used to
Manufacture the Product to confirm that such facilities are in compliance with
Applicable Laws and the Governmental Approvals. Atrix, at its sole cost and
expense, may have a representative(s) accompany MediGene's representative(s) on
any such inspection or audit.

     Section 7.06. FAILURE TO SUPPLY.

          (a) Atrix shall immediately notify MediGene if Atrix is unable to fill
     any order placed by MediGene pursuant to Section 8.07. If Atrix is unable
     to cure such failure within fifteen (15) business days after such notice,
     Atrix shall, within five (5) business days after the expiration of such
     cure period, make arrangements with the Second Source for the Second Source
     to take commercially reasonable steps to commence the Manufacture of the
     Product and to sell to Atrix the Product until such time as Atrix is again
     able to Manufacture the Product; provided, however, any consequent
     incremental costs which result by reason of the use of the Second Source
     under this Section 7.06(a) shall be the sole cost and liability of Atrix.

          (b) Subject to Section 7.06(c), if Atrix is unable (including due to
     reasons of Force Majeure) to supply Product to MediGene for a period of
     forty-five (45) business days or more or if Atrix notifies MediGene that
     Atrix and the Second Source will be unable to perform under Section
     7.06(a), then upon such event, Atrix shall be deemed to have granted to
     MediGene and MediGene shall be deemed to have, without any further action
     by either Party, a non-exclusive royalty-free license under the Atrigel(R)
     Technology only to the extent necessary and sufficient to Manufacture the
     Product for sale or distribution in the Territory. At such time as Atrix or
     the Second Source is again able to Manufacture the Product, such license to
     MediGene will terminate and Atrix will


                                       22



     regain its exclusive right to Manufacture and supply the Product to
     MediGene, subject to the terms and conditions of the manufacturing
     agreement between MediGene and a Third Party manufacturer. Atrix, upon
     MediGene's written request, shall provide MediGene or any Third Party
     manufacturer chosen by MediGene within two (2) weeks of the date of such
     request with all Atrigel(R) Know-How related to the Manufacturing Process,
     but only to the extent necessary and sufficient to exercise its rights
     hereunder. Atrix shall also provide MediGene with any additional
     documentation and materials, at MediGene's expense, reasonably necessary to
     Manufacture the Product in the Territory in accordance with the license
     granted hereunder. If MediGene, enters into an agreement with a Third Party
     to Manufacture the Product, MediGene shall use commercially reasonable
     efforts to limit any such agreement to as short of period of time as
     commercially reasonable after giving effect to the period of time Atrix or
     the Second Source is expected to be unable to supply the Product. Any Third
     Party manufacturer shall execute confidentiality agreements with Atrix in
     form and substance reasonably satisfactory to Atrix. If necessary, Atrix
     will support the implementation of its Atrigel Know-How for the Manufacture
     of the Product by providing appropriate employees giving the required
     advice at the premises of MediGene or such Third Party. The cost for these
     employees will be borne by MediGene.

          Except as set forth in this Section 7.06(b), any additional costs and
     expenses reasonably incurred by MediGene shall be borne by Atrix.

          (c) Notwithstanding the foregoing, Atrix shall not be deemed to be
     unable to fill any order for Products placed by MediGene if Atrix's
     inability to fill any order for Products arises as a result of [**]
     increase in MediGene's order for Products over MediGene's prior firm
     forecast for each such Product. [**]

     Section 7.07. ALLOCATION. If Atrix exercises its rights to co-market under
Article XIII and if Atrix is unable to supply all of the requirements of the
Product, and quantities ordered by MediGene in accordance with Section 8.07,
then Atrix shall allocate the resources available to it so that MediGene
receives at least its proportional share of available supplies as determined
based on reasonable forecasts (taking into consideration past sales and sales
performance against forecast) of MediGene and Atrix.

                                  ARTICLE VIII

                                PURCHASE AND SALE

     Section 8.01. PURCHASE PRICE AND PAYMENT. Atrix shall sell, and MediGene
shall purchase, each Product at a price equal to the Atrix Manufacturing Cost
for each such Product, including any adjustments pursuant to Section 8.02 (the
"Purchase Price"). Atrix shall invoice MediGene monthly for all Product and
Demonstration Samples shipped by Atrix to MediGene and payment shall be due
thirty (30) days from receipt of the invoice.

               (i) if MediGene in good faith disputes the amount of the Adjusted
          Atrix Manufacturing Cost, then MediGene shall notify Atrix of this
          fact and such dispute shall be resolved by the Parties within thirty
          (30) days from the date of notice to MediGene of the Adjusted Atrix
          Manufacturing Cost. If such dispute cannot be resolved to the mutual
          satisfaction of the Parties within such thirty (30) day period then
          either Party may request that the dispute be submitted to the Chief
          Executive Officers of Atrix and MediGene, respectively, for joint
          resolution. If the dispute is not jointly resolved by the Parties'
          respective Chief Executive Officers within ten (10) days from
          submission to the Parties' respective Chief Executive Officers then
          Atrix shall be entitled to pursue any and all remedies at law
          available to it. In no event will the dispute resolution period exceed
          a maximum of forty (40) days unless otherwise agreed in writing by the
          Parties; and

               (ii) MediGene shall pay for Product ordered during the dispute
          period at the Purchase Price in effect prior to Atrix's notice of the
          Adjusted Atrix Manufacturing Cost. If upon resolution of any dispute
          the Purchase Price is greater than the Purchase Price paid by MediGene
          during the dispute period, Atrix will invoice MediGene for the
          difference and MediGene shall pay the same promptly upon receipt of
          such invoice. If upon resolution of any dispute the Purchase Price is
          lower than the Purchase Price paid by MediGene during the dispute
          period, Atrix will reimburse MediGene for the difference paid during
          the dispute period, [**].

          (b) If at any time following twelve (12) months from the date of the
     First Commercial Sale of each Product, on a Product by Product basis, the
     Atrix Manufacturing Cost is in excess of the Twelve Month Cost then
     MediGene may request that the Parties meet to review and discuss the Atrix
     Manufacturing Cost. [**] Notwithstanding the foregoing, commencing twelve
     (12) months from the date of the First Commercial Sale of each Product, on
     a Product by Product basis, in the event that the total increase results in
     an increased Atrix Manufacturing Cost which becomes, in MediGene's sole
     judgment, commercially non-viable for a given Product in a given country in
     the Territory, MediGene shall have the right, in its sole discretion, to

               (i) [**];

               (ii) [**]; and

               (iii) [**]

          (c) Commencing twelve (12) months from the date of First Commercial
     Sale of each Product MediGene shall have the right, at its sole cost and
     expense, to cause an independent, certified public accountant reasonably
     acceptable to Atrix to audit those records of Atrix relating to the
     calculation of the Atrix Manufacturing Cost and/or the Adjusted Atrix
     Manufacturing Cost for the sole purpose of verifying the Atrix
     Manufacturing Cost or the Adjusted Atrix Manufacturing Cost, respectively.
     Such audits may be exercised during normal business hours no more than once
     in a twelve (12) month period upon at least ten (10) days prior written
     notice. MediGene shall pay all of the costs of such audit unless such audit
     discloses an overstatement of the Atrix Manufacturing Cost or the Adjusted
     Atrix Manufacturing Cost by more than [**] of the amount claimed or stated
     as the Atrix Manufacturing Cost or the Adjusted Atrix Manufacturing Cost,
     respectively, for the preceding year. In such case, Atrix shall pay all of
     the costs of such audit.

     Section 8.03. LABELING AND ARTWORK.

          (a) After execution of this Agreement, Atrix shall have the right to
     review and comment upon any labeling and proposed changes to the labeling
     of the Product and to participate in discussions with the Competent
     Authorities concerning any labeling or proposed labeling change in
     accordance with Section 8.03(c). Notwithstanding the above, MediGene shall
     make the final decision with regard to any labeling or labeling revisions,
     provided that MediGene will consider, in making its decision, the effect
     such labeling or labeling revision will have on the marketing and sale of
     the Product outside the Territory.

          (b) MediGene will approve all artwork developed for inclusion in the
     Product packaging, including carton labels, package inserts, etc. If
     MediGene wishes to institute changes in labeling artwork, both Parties will
     develop a mutually acceptable implementation schedule. The actual cost of
     implementing such change will be at MediGene's sole cost and expense,
     including any materials made obsolete by MediGene's changes to the artwork.
     Atrix shall not alter, change or in any way modify the artwork, which has
     previously been approved, for any reason, without prior written
     authorization from MediGene, provided that such approved artwork shall
     conform to all Applicable Laws. Notwithstanding the foregoing, MediGene
     shall have the final say on any change in such artwork, provided that
     MediGene will consider, in making its decision, the effect any such change
     will have on the marketing and sale of the Product outside the Territory
     and provided further that such change is in compliance with all Applicable
     Laws in the Territory.

          (c) MediGene shall provide Atrix with notice within forty-eight (48)
     hours of notification of any scheduled meeting or conference with any
     Competent Authority with

- ----------
**   Confidential Treatment Requested.


                                       25



     respect to any labeling or proposed labeling change. MediGene shall inform
     such Competent Authority that Atrix may desire to be present at such
     meeting or conference; provided that Atrix's right to be present is subject
     to approval by such Competent Authority and subject to Atrix being
     available at the time and date established by such Competent Authority.
     MediGene shall use reasonable efforts to secure a time and date for such
     meeting or conference that is reasonably acceptable to Atrix; provided,
     however, that MediGene alone has the right to make the final decision on
     all such matters.

     Section 8.04. PURCHASE FORMS. Purchase orders, purchase order releases,
confirmations, acceptances and similar documents submitted by a Party in
conducting the activities contemplated under this Agreement are for
administrative purposes only and shall not add to or modify the terms of the
Agreement. To the extent of any conflict or inconsistency between this Agreement
and any such document, the terms of this Agreement shall govern.

     Section 8.05. CONFIRMATION. Atrix shall confirm each purchase order within
five (5) business days from the date of receipt of a purchase order and shall
supply the Product within a maximum of sixty (60) days from the date of
acceptance of a purchase order, or later if so specified in the purchase order
during the first twelve months after the First Commercial Sale of the Product.
[**] Failure of Atrix to confirm any purchase order shall not relieve Atrix of
its obligation to supply Product ordered by MediGene in conformity with this
Agreement.

     Section 8.06. DELIVERY. Delivery terms for Product and Demonstration
Samples shall be FOB Atrix's manufacturing facility at Fort Collins, Colorado,
or FOB the Second Source's manufacturing facility. Atrix shall ship Product and
Demonstration Samples in accordance with MediGene's purchase order form or as
otherwise directed by MediGene in writing. Title to any Product or Demonstration
Samples purchased by MediGene shall pass to MediGene upon the earlier of (i) a
common carrier accepting possession or control of such Product or Demonstration
Samples, as applicable, or (ii) passage of such Product or Demonstration
Samples, as applicable, from the loading dock of Atrix's facilities or the
loading dock of the Second Source's facilities, as applicable, to MediGene or
its agent.

     Section 8.07. FORECASTS AND ORDERS.

          (a) Not later than six (6) months following submission of the NDA or
     other applicable regulatory filing on a country by country basis, MediGene
     will provide Atrix with a twelve (12) month forecast of MediGene's
     requirement of each Product, on a Product by Product basis, including
     Demonstration Samples, and on a country by country basis as follows (the
     "Initial Forecast"):

               (i) For the first twelve (12) months of the forecast for each
          Product, the forecasts shall be provided quarterly, no less than
          forty-five (45) days prior to the beginning of each quarter. Said
          requirements will be based on standard production planning parameters
          including but not limited to sales forecasts, sales demand forecasts,
          promotional forecasts, inventory requirements, and the like.

- ----------
**   Confidential Treatment Requested.


                                       26



          The first two (2) quarters of the twelve (12) month forecast will be
          stated in monthly requirements. The second two (2) quarters of the
          twelve (12) month forecast will be total requirement by stock keeping
          unit and will be stated as quarterly requirements. The first three (3)
          months of the twelve (12) month forecast will be firm orders to
          purchase. The second three (3) months will be allowed to be flexed
          from the previous forecast by plus or minus [**] per month until fixed
          by the subsequent forecast; provided that the aggregate adjustment
          from the quantity set forth in the previous forecast for such three
          (3) month period shall not exceed [**] in aggregate during that three
          (3) month period. [**]

               (ii) After the first twelve (12) months MediGene will provide to
          Atrix a rolling twelve (12) month forecast for each Product with the
          first three (3) months of the rolling twelve (12) month forecast a
          firm order to purchase. Each order in the rolling twelve (12) month
          forecast shall be provided monthly, no less than twenty (20) days
          prior to the beginning of each month. All orders will be for full
          batch quantities.

          (b) It is understood that Atrix [**] will produce Product or
     Demonstration Sample upon receipt of that portion of MediGene's forecasts
     that constitute firm orders to purchase. The above periods whether fixed or
     flexible will be adjusted based upon existing lead times at time of start
     up.

          (c) MediGene agrees to purchase a sufficient amount of Product to
     enable MediGene to carry sufficient inventory to allow for fluctuations in
     sales demand so as to allow Atrix reasonable lead time to meet increased
     demand. Atrix will use commercially reasonable efforts to meet any increase
     in demand in excess of the allowed adjustment, but will not be obligated to
     do so; provided, however, notwithstanding anything to the contrary in this
     Section 8.07, Atrix shall be obligated to [**]. All forecasts will be made
     by MediGene to Atrix in good faith based upon standard commercial
     parameters. From time to time after the Effective Date, the Parties shall
     consider whether, in light of market demand, manufacturing capacity,
     inventory levels and other pertinent factors, to revise the schedule for
     delivery of forecasts and, if appropriate, negotiate in good faith to
     revise such schedule.

          (d) The Launch Quantity of the Product when delivered to the common
     carrier shall not have an expiration date of less than [**] from the date
     of such delivery, provided (a) Product other than the Launch Quantity shall
     not have an expiration date of less than [**] once real time stability data
     is submitted by Atrix to the respective Competent Authority, and/or (b) as
     the Parties may otherwise agree in writing on a case by case basis.

          (e) In the event MediGene does not receive a Marketing Authorization
     in a specified country in the Territory, but Atrix nevertheless has
     Manufactured the Launch

     Quantity of the Product for sale in such country in the Territory, the
     Atrix Manufacturing Cost attributable to the Manufacture of the Launch
     Quantity for sale in such country shall be borne equally by the Parties
     after deducting the cost of any Product which MediGene can sell in another
     country in the Territory and the cost of direct materials Atrix could
     otherwise use in the manufacture of other products.

     Section 8.08. DEMONSTRATION SAMPLES. Pursuant to the provisions of Section
8.07 above, Atrix shall supply to MediGene such quantities of Demonstration
Samples as MediGene may reasonably request to be used solely for training
purposes (and not for sale), and not for human use, for so long as MediGene
retains a license pursuant to Sections 3.02 and 3.03 in the specific country in
the Territory where the Demonstration Samples are to be used for training
purposes. Demonstration Samples shall be sold by Atrix to MediGene at [**] for
such Demonstration Samples. MediGene shall not use the Demonstration Samples for
any purpose other than as set forth in this Section 8.08.

                                   ARTICLE IX

                       WARRANTY, REJECTION AND INSPECTIONS

     Section 9.01. ATRIX WARRANTY. Atrix represents and warrants to MediGene
that (i) the Product delivered pursuant to this Agreement shall comply with the
Specifications at the date of delivery; (ii) the Product to be sold in the
Territory is not adulterated or misbranded under Applicable Laws in the
Territory at the date of delivery; (iii) at the time of Manufacture and delivery
to MediGene the Product will be, and is, free from any defects, liens and
encumbrances and MediGene shall receive good and marketable title to the
Product, and (iv) at the date of Manufacture that Atrix has the right, and to
the best of its knowledge each Second Source has the right, to Manufacture and
label the Product, and (v) to its knowledge no restrictions for the import of
the Product into the Territory exist at the time of Manufacture and delivery to
MediGene.

     EXCEPT AS OTHERWISE SET FORTH HEREIN, ATRIX MAKES NO OTHER WARRANTIES OF
ANY OTHER KIND, INCLUDING BUT NOT LIMITED TO ANY WARRANTY OF MERCHANTABILITY (AS
DESCRIBED IN SECTION 4-2-314 OF THE U.C.C.) OR FITNESS OF THE PRODUCT AND
DEMONSTRATION SAMPLES FOR ANY PURPOSE (AS DESCRIBED IN SECTION 4-2-315 OF THE
U.C.C.), AND ATRIX EXPRESSLY DISCLAIMS ANY SUCH OTHER WARRANTIES WITH RESPECT TO
THE PRODUCT AND DEMONSTRATION SAMPLES, EITHER EXPRESS OR IMPLIED.

     Section 9.02. REJECTION OF PRODUCT FOR FAILURE TO CONFORM TO
SPECIFICATIONS. MediGene shall have forty-five (45) days after the receipt of
any Shipment to determine conformity of the Shipment to the Specifications
and/or Applicable Laws, except for hidden defects. A "hidden defect" shall mean
a defect in the Product not discovered by MediGene during its testing of the
Product in accordance with generally accepted industry

- ----------
**   Confidential Treatment Requested.


                                       28



testing procedures and which would not be a defect normally expected to be
discovered in accordance with such testing. If testing of such Shipment shows a
failure of the Shipment to meet the Specifications and/or Applicable Laws,
MediGene may return the entire Shipment, or any portion thereof, to Atrix at
Atrix's expense within a reasonable time following the above described testing,
provided that notice of non-conformity is received by Atrix from MediGene within
forty-five (45) days of MediGene's receipt of said Shipment except for hidden
defects. MediGene shall have the right to request that Atrix provide to
MediGene, within thirty (30) days after such notice is received by it, Product
that meets the Specifications and Applicable Laws or to promptly provide
MediGene with full credit for the Purchase Price paid by MediGene for the
returned Product. In case of a hidden defect, MediGene shall have the right to
request that Atrix provide to MediGene, within thirty (30) days after a notice
concerning a hidden defect is received by it, Product that meets the
Specifications and Applicable Laws or to promptly provide MediGene with full
credit for the Purchase Price paid by MediGene for the returned Product. In
either case the cost of freight and handling to return or replace the returned
Product shall be at the expense of Atrix. If MediGene does not notify Atrix of
the non-conformity of the Product within forty-five (45) days of receipt of said
Shipment, the Product shall be deemed to meet the Specifications, the Packaging
Specifications and Applicable Laws, except for hidden defects. Notwithstanding
anything in this Agreement to the contrary, the Parties may agree to a return of
the Product or an adjustment in the Purchase Price in the event of any failure
or defect in the Product. Should there be a discrepancy between MediGene's test
results and the results of testing performed by Atrix, such discrepancies shall
be finally resolved by testing performed by an independent Third Party mutually
agreed upon by MediGene and Atrix. The costs of such testing shall be borne by
the Party against whom the discrepancy is resolved. In the event Product has
been previously returned to Atrix and an independent Third Party determines that
the Product meets the Specifications, MediGene shall be responsible for all
costs associated with the return.

     Section 9.03. MEDIGENE INSPECTIONS. Atrix shall upon reasonable (but not
less than five (5) business days) prior written notice by MediGene and during
normal business hours, allow MediGene and cause any sub-contractors and the
Second Source to allow MediGene, to inspect and audit Atrix's facilities, the
facilities of Atrix's sub-contractors and the facilities of the Second Source
used to Manufacture the Product and the Demonstration Samples, twice annually,
to confirm that the facilities and the equipment, personnel and operating and
testing procedures used by Atrix, Atrix's subcontractor(s) and the Second Source
in the Manufacture, testing, storage and distribution of the Product are in
compliance with Applicable Laws and the Governmental Approvals; provided that
such inspection does not interfere with Atrix's, Atrix's sub-contractor(s)' and
the Second Source's normal operations or cause Atrix, Atrix's sub-contractor(s)
and the Second Source to violate or be in breach of any confidentiality
agreements with any Third Party pertaining to other products.

          (a) Each Party, including its permitted sublicensees, shall advise the
     other Party, by telephone or facsimile, immediately but in no event later
     than twenty-four (24) hours after a Party, or its sublicensees, becomes
     aware of any potentially serious or unexpected adverse event (including
     adverse drug experiences, as defined in Applicable Laws) (an "ADE")
     involving the Product or the Demonstration Samples. Such advising Party
     shall provide the other Party with a written report delivered by confirmed

     a copy of which is attached hereto as Exhibit F. In the event the SOP is
     modified or amended during the term of this Agreement, MediGene shall
     provide Atrix with copies of any such modification or amendment to the SOP
     for Atrix's prior approval, which will not be unreasonably withheld,
     conditioned or delayed, at least five (5) business days prior to such
     amendment taking effect. MediGene shall designate a qualified person under
     Applicable Laws to be responsible for ADE reporting in each country in the
     Territory.

          (d) If the report of an ADE causes a Competent Authority to request
     labeling revision as a result of an ADE or that a Phase IV surveillance
     program be conducted, then the Parties shall promptly enter into
     discussions and shall mutually agree on all of the material terms and
     conditions of such labeling revision or Phase IV surveillance program;
     provided, however the costs of such labeling revision or Phase IV
     surveillance program shall be borne [**]. MediGene shall have the authority
     to make the final decision with regard to any labeling revisions provided
     that MediGene will consider, in making its decision, the effect any such
     labeling revisions will have on the marketing and sale of the Product
     outside the Territory. MediGene agrees that should Applicable Laws require
     that any such interim data and results from such Phase IV surveillance
     programs be prepared in written form, MediGene shall comply with such
     requirements and provide all such information in writing to MediGene and
     the Competent Authorities in accordance with Applicable Laws. MediGene

     Section 11.01. MAINTENANCE OF PATENTS OR MARKS.

          (a) Atrix shall, at Atrix's expense and to the extent commercially
     reasonable, maintain and protect the Atrigel(R) Patent Rights and the Marks
     in all countries in the Territory; provided however, that upon written
     request by Atrix, MediGene shall, at no cost or expense to MediGene,

     filing, prosecution and maintenance of any patent application or patent
     within the Program Technology desires to abandon such patent application or
     patent, or if such Party later declines responsibility for such patent
     application or patent, such Party shall provide reasonable prior written
     notice to the other Party of its intention to abandon or

**   Confidential Treatment Requested.


                                       32



     decline responsibility, and the other Party shall have the right, but not
     the obligation, to prepare, file, prosecute, and maintain any such patent
     application or patent within the Program Technology. The Parties shall
     share equally the costs of filing, prosecuting and maintaining patents or
     patent applications within the Program Technology. In addition, each Party
     shall provide the other Party the opportunity to review, consult with and
     assist such Party in the preparation of filing, prosecuting and maintaining
     such patents and patent applications.

     Section 11.02. PROSECUTION OF INFRINGEMENT.

          (a) During the Term, each Party shall give prompt notice to the other
     of any Third Party act which may infringe the Atrigel(R) Patent Rights or
     the Marks in the Territory and shall cooperate with each other to terminate
     such infringement without litigation. Atrix shall, at its sole expense,
     prosecute the judicial or administrative proceedings against such Third
     Party infringement. MediGene shall provide such assistance and cooperation
     to Atrix as may be necessary to successfully prosecute any action against
     Third Party infringement at Atrix's expense and may deduct the expenses
     thereof from any amounts payable to Atrix under this Agreement.

          In the event Atrix fails to institute proceedings against any Third
     Party infringement of the Atrigel(R) Patent Rights and/or the Marks within
     forty-five (45) days after notice given by either Party to the other of
     said Third Party infringement, MediGene may take such action as it deems
     appropriate, including without limitation, the filing of a lawsuit against
     such Third Party. In such event Atrix will provide such assistance and
     cooperation to MediGene as may be necessary, at MediGene's expense, and
     MediGene may deduct all costs and expenses of such actions against any
     amount payable to Atrix under this Agreement and retain all amounts awarded
     in such action.

          (b) In the event any patent included in the Program Technology is
     infringed by a Third Party, the Party responsible for prosecution and
     maintenance of the applicable Program Technology under Section 11.01(b)
     shall have the right to bring and control such action or proceeding, using
     counsel reasonably acceptable to the Parties, and the other Party shall
     provide such assistance and cooperation to the Party bringing such action
     as may be necessary to successfully prosecute any action against such Third
     Party. The Parties shall share equally in the costs with respect thereto.

          In the event Atrix or MediGene, as the case may be, fails to institute
     proceedings against any Third Party infringement of the Program Technology
     within the earlier of (i) the time period required under Applicable Laws or
     (ii) forty-five (45) days after notice given by either Party to the other
     of said Third Party infringement, the other Party may take such action as
     it deems appropriate, including without limitation, the filing of a lawsuit
     against such Third Party. In such event Atrix or MediGene, as the case may
     be, will provide such assistance and cooperation to the other Party as may
     be necessary, at the other Party's expense, and such Party may deduct, in
     the case of MediGene, or add, in the case of Atrix, all costs and expenses
     of such actions against any amount payable to, in the case of MediGene, or
     receivable from, in the case of Atrix, the other Party under this Agreement
     and retain all amounts awarded in such action.


                                       33



          (c) Neither Atrix nor MediGene may settle an action or proceeding
     against an infringer related to the Program Technology, and MediGene may
     not settle an action or proceeding against an infringer related to
     Atrigel(R) Technology, with respect to an infringement without the written
     consent of the other Party. Such consent shall not be unreasonably withheld
     or delayed, but may be withheld if such settlement would materially and
     adversely affect the interest of such Party, including Atrix's rights
     hereunder or Atrix's rights in the Atrigel(R) Technology.

     Section 11.03. INFRINGEMENT CLAIMED BY THIRD PARTIES. In the event a Third
Party commences, or threatens to commence, a judicial or administrative
proceeding against a Party to this Agreement and such proceeding pertains to the
Atrigel(R) Patent Rights or Marks, the Party against whom such proceeding is
threatened or commenced shall give prompt notice to the other Party. Atrix
shall, at its sole cost and expense, defend any and all such claims or
proceedings and shall indemnify and hold harmless MediGene from any and all
liabilities, costs and expenses, including, without limitation, attorneys' fees,
incurred with respect to any such claim or proceeding and MediGene shall provide
such assistance and cooperation to Atrix as may be necessary to successfully
defend any such claim or proceeding. In the event a Third Party commences, or
threatens to commence, a judicial or administrative proceeding against a Party
to this Agreement and such proceeding pertains to the Program Technology, the
Party responsible for prosecution and maintenance of the applicable Program
Technology under Section 11.01(a) shall have the right to defend any and all
such claims or proceeding, using counsel reasonably acceptable to the Parties,
and the Parties shall share equally the costs with respect thereto; provided,
however, if such Party elects not to defend such claim or fails to use
commercially reasonable efforts to defend such claim, the other Party shall have
the right to control the defense of such claims by counsel of its own choice at
the cost of the Party who initially had the right to defend such claim.

                                   ARTICLE XII

thereafter, each Party shall maintain all Confidential Information of the other
Party as confidential and shall not disclose any such Confidential Information
to any Third Party or use any such Confidential Information for any purpose,
except (a) as expressly authorized by this Agreement, (b) as required by law,
rule, regulation or court order (provided that the disclosing Party shall first
notify the other Party and shall use commercially reasonable efforts to obtain
confidential treatment of any such information required to be disclosed), or (c)
to its Affiliates, employees, agents, consultants and other representatives to
accomplish the purposes of this Agreement, so long as such persons are under an
obligation of confidentiality no less stringent than as set forth herein. Each
Party may use such Confidential Information only to the extent required to
accomplish the purposes of this Agreement. Each Party shall use at least the
same standard of care as it uses to protect its own Confidential Information to
ensure that its Affiliates, employees,

                                       34



agents, consultants and other representatives do not disclose or make any
unauthorized use of the other Party's Confidential Information. Each Party shall
promptly notify the other Party upon discovery of any unauthorized use or
disclosure of the other Party's Confidential Information.

     Section 12.02. DISCLOSURE OF AGREEMENT. Neither Party shall release to any
Third Party or publish in any way any non-public information with respect to the
terms of this Agreement without the prior written consent of the other Party,
which consent shall not be unreasonably withheld, except for the disclosure by a
Party of the terms of this Agreement to lenders, investment bankers and other
financial institutions of its choice solely for purposes of financing the
business operations of such Party; provided such Party uses reasonable efforts
to obtain a signed confidentiality agreement with any such financial institution
with respect to such information on terms substantially similar to those
contained in this Article XII and except as provided in Section 20.11. Nothing
contained in this paragraph shall prohibit either Party from filing this
Agreement as required by the rules and regulations of the Securities and
Exchange Commission, national securities exchanges (including those located in
countries outside of the United States) or the Nasdaq Stock Market; provided the
disclosing Party discloses only the minimum information required to be disclosed
in order to comply with such requirements, including requesting confidential
treatment of this Agreement (after consultation with the other Party) and filing
this Agreement in redacted form.

                          ATRIX'S OPTION TO MARKET THE

reasonably practicable after such Indemnitee becomes aware of such claim,
provided that the failure to notify the Indemnitor shall not relieve the
Indemnitor from any liability except to the extent that such failure to notify
actually adversely impacts the Indemnitor's ability to defend such claim. Such
notice shall state that the Indemnitor is required to indemnify the Indemnitee
for a Loss and shall specify the amount of Loss and relevant details thereof.

respect to the responsibility of the Indemnitor with respect to the Loss in

against the Indemnitee without the consent of the Indemnitee provided that the
terms thereof: (a) provide for the unconditional release of the Indemnitee; (b)
require the payment of compensatory monetary damages by Indemnitor only; and (c)
expressly state that neither the fact of settlement nor the settlement agreement
shall constitute, or be construed or interpreted as, an admission by the

settled. No Indemnitee shall pay or voluntarily permit the determination of any
liability which is subject to any such action while the Indemnitor is
negotiating the settlement thereof or contesting the matter, except with the
prior written consent of the Indemnitor, which consent shall not be unreasonably
withheld or delayed. If the Indemnitor fails to give Indemnitee notice of its
intention to defend any such action as provided herein, the Indemnitee involved
shall have the right to assume the defense thereof with counsel of its choice,
at the Indemnitor's expense, and defend, settle or otherwise dispose of such
action. With respect to any such action which the Indemnitor shall fail to

and other expenses of defense).

and any other applicable federal or state securities laws and (B) any other
Applicable Law. The Parties hereto shall cooperate with each other in connection
with the making of all such filings, including by providing copies of all such
documents to the other Party's counsel (subject to appropriate confidentiality
restrictions) prior to filing and, if requested, by accepting all reasonable
additions, deletions or changes suggested in connection therewith. Without
limiting the generality of the foregoing, each Party shall take or omit to take
such action as the other Party shall reasonably request to cause the Parties to
obtain any material Governmental Approvals and/or the expiration of applicable
waiting periods, provided that the foregoing shall not obligate either Party to
take or to omit to take any action (including, without limitation, the
expenditure of funds or any holding separate and agreeing to sell or otherwise
dispose of assets, categories of assets or businesses) as in the good faith
opinion of such Party, would cause a material adverse effect on a Party.

     Section 16.11. EQUITABLE RELIEF. The Parties understand and agree that
because of the difficulty of measuring economic losses to the non-breaching
Party as a result of a breach of the


                                       41



covenants set forth in this Article XVI, and because of the immediate and
irreparable damage that may be caused to the non-breaching Party for which
monetary damages would not be a sufficient remedy, the Parties agree that the
non-breaching Party will be entitled to seek specific performance, temporary and
permanent injunctive relief, and such other equitable remedies to which it may
then be entitled against the breaching Party. This Article XVI shall not limit
any other legal or equitable remedies that the non-breaching Party may have
against the breaching Party for violation of the covenants set forth in this
Article XVI. The Parties agree that the non-breaching Party shall have the right
to seek relief for any violation or threatened violation of this Article XVI by
the breaching Party from any court of competent jurisdiction in any jurisdiction
authorized to grant the relief necessary to prohibit the violation or threatened
violation of this Article XVI. This Article XVI shall apply with equal force to
the breaching Party's Affiliates.

                                  ARTICLE XVII

                                 PRODUCT RECALL

     Section 17.01. PRODUCT RECALLS OR WITHDRAWAL. If at any time or from time
to time any Competent Authority of any country requests a Party to recall the
Product or if a voluntary recall of the Product is contemplated by either Party
(collectively, a "Recall"), then the Party to whom such request is made or the
Party contemplating such Recall, as the case may be, shall immediately notify
the other Party. Neither Party shall carry out a voluntary Recall in the
Territory without the prior written approval of the other Party, which approval
shall not be unreasonably withheld, conditioned or delayed by either Party. Any
Recall in the Territory shall be carried out by MediGene in as expeditious a
manner as reasonably possible to preserve the goodwill and reputation of the
Product and the goodwill and reputation of the Parties. MediGene shall in all
events be responsible for conducting any Recall in the Territory, market
withdrawals or corrections with respect to the Product in the Territory.
MediGene shall maintain records of all sales and distribution of Product and
customers sufficient to adequately administer a Recall, market withdrawal or
correction for the period required by Applicable Law. Atrix shall be
responsible, at its sole cost and expense, for conducting any Recall outside of
the Territory and agrees to notify MediGene immediately if a Competent Authority
outside of the Territory has requested a Recall or if Atrix is contemplating a
voluntary Recall outside of the Territory; provided, however, that any such
voluntary Recall shall be subject to Atrix's contractual obligations with Third
Parties outside the Territory and, if Atrix is permitted to exercise discretion
under such contractual obligations, Atrix shall consider the effect of such
voluntary recall on the marketing and sale of the Product in the Territory.

     Section 17.02. RECALL COSTS. MediGene shall be responsible for conducting
any Recall in the Territory and the cost and expense of a Recall shall be
allocated as follows:

          (a) if such Recall is a voluntary Recall or shall be due to tampering
     or other cause, other than a manufacturer's defect, but not due to the
     negligence or misconduct of the Parties, or the breach by a Party of its
     warranties or obligations hereunder, then MediGene and Atrix shall [**] of
     the costs and expenses incurred by MediGene in

- ----------
**   Confidential Treatment Requested.


                                       42



     connection with such Recall, including, without limitation, all product
     credits and returns, freight and shipping costs and product disposal
     expenses. In such event, Atrix agrees to pay MediGene within ten (10) days
     after its receipt from MediGene of any invoice(s) assessing Atrix [**] of
     these said costs, as listed above;

          (b) if such Recall shall be due to manufacturer's defect or the
     negligence or the breach by Atrix of its warranties or obligations
     hereunder or the misconduct of Atrix, all such costs and expenses shall be
     borne and paid solely by Atrix and Atrix will reimburse MediGene for any
     such costs and expenses paid by MediGene within ten (10) days of receipt of
     an invoice for such costs and expenses from MediGene, and if not so paid
     MediGene shall have the right to offset such amounts against amounts
     otherwise due by MediGene to Atrix hereunder; and

          (c) if such Recall is due to the negligence or the breach by MediGene
     of its warranties or obligations hereunder or the misconduct of MediGene,
     all such costs and expenses shall be borne and paid solely by MediGene and
     MediGene will reimburse Atrix for any such costs and expenses paid by Atrix
     within thirty (30) days of receipt of an invoice and appropriate
     documentation for such costs and expenses from Atrix.

     Section 17.03. NOTIFICATION OF COMPLAINTS. Each Party agrees that
throughout the Term of this Agreement, and with respect to all Product or
Demonstration Samples supplied and purchased under this Agreement, after the
termination of this Agreement, it will (i) notify the other Party immediately of
all available information concerning any complaint, product defect reports, and
similar notices received by either Party with respect to the Product or
Demonstration Samples, whether or not determined to be attributable to the
Product or Demonstration Samples and (ii) with respect to an ADE, comply with
the provisions of Section 10.04. MediGene, in consultation with Atrix, shall
define and implement regulatory compliance procedures, including, without
limitation, action plans and an SOP for product defect reporting and will handle
all product complaints in the Territory. In connection with any such product
complaint Atrix shall cooperate as reasonably requested by MediGene including
performing any testing and follow-up investigations mutually agreed upon by the
Parties.

     Section 17.04. NOTIFICATION OF THREATENED ACTION. Throughout the duration
of this Agreement and with respect to all Product supplied and purchased under
this Agreement, after the termination of this Agreement, each Party shall
immediately notify the other Party of any information it receives regarding any
threatened or pending action, inspection or communication by or from a concerned
Competent Authority which may affect the safety or efficacy claims of the
Product or the continued marketing of the Product. Upon receipt of such
information, the Parties shall consult with each other in an effort to arrive at
a mutually acceptable procedure for taking appropriate action.

                                  ARTICLE XVIII

                                    INSURANCE

     Section 18.01. INSURANCE. Each Party shall, at its sole cost and expense,
obtain and keep in force sufficient comprehensive general liability insurance,
including any applicable self-


                                       43



insurance coverage, with bodily injury, death and property damage including
contractual liability and product liability coverage.

                                   ARTICLE XIX

                          TERM; DEFAULT AND TERMINATION

     Section 19.01. TERM. This Agreement shall commence as of the Effective Date
and shall expire on a country-by-country basis on the expiration of the last
applicable Atrigel(R) Patent Right, or any other patents obtained by Atrix with
regard to the Product, in such country (the "Term").

     Section 19.02. TERMINATION BY EITHER PARTY FOR CAUSE. Either Party may
terminate this Agreement prior to the expiration of the Term upon the occurrence
of any of the following:

          (a) Upon or after the cessation of operations of the other Party or
     the bankruptcy, insolvency, dissolution or winding up of the other Party
     (other than dissolution or winding up for the purposes or reconstruction or
     amalgamation); or

          (b) Upon or after the breach of any material provision of this
     Agreement by the other Party if the breaching Party has not cured such
     breach within sixty (60) days after written notice thereof by the
     non-breaching Party; provided, however, if any such breach relates solely
     to one or more Products, then the non-breaching Party may only terminate
     this Agreement to the extent it applies to such Product or Products and
     this Agreement shall remain in effect as it applies to all other Products.

     Section 19.03. TERMINATION BY ATRIX. Atrix may terminate this Agreement
prior to the expiration of the Term with respect to any country in the Territory
upon the occurrence of any of the following:

          (a) Upon the failure by MediGene to pay for fifteen (15) days from
     receipt of notice thereof from Atrix, pursuant to the terms of Section
     20.08: (i) any Royalty payment, or portion thereof, pursuant to Section
     4.02; (ii) any milestone payments, or portion thereof, pursuant to Section
     4.03 or Section 4.04; or (iii) the Purchase Price due to Atrix under
     Section 8.01 of this Agreement; provided, however, that this subsection (a)
     shall not apply to any Royalty payment, or portion thereof, pursuant to
     Section 4.02, which is the subject of a good faith dispute (a "Disputed
     Amount") between MediGene and Atrix. Further, MediGene shall pay interest
     on any Disputed Amount at a rate equal to the Prime Rate of Interest to
     begin accruing on a daily basis from the date such payment was due and
     continuing until such payment is received by Atrix. Any Disputed Amount
     shall be resolved by the Parties within ninety (90) days from the date
     MediGene notifies Atrix of a good faith dispute; provided, however, if the
     Disputed Amount cannot be resolved to the mutual satisfaction of the
     Parties within such ninety (90) day period then either Party may request
     that the dispute be submitted to the Chief Executive Officers of Atrix and
     MediGene, respectively, for joint resolution. If the Disputed Amount is not
     jointly resolved by the Parties' respective Chief Executive Officers within
     ten (10) days from submission to the Parties' respective Chief Executive
     Officers then


                                       44



     Atrix shall be entitled to pursue any and all remedies at law available to
     it. In no event will the dispute resolution period exceed a maximum of one
     hundred (100) days unless otherwise agreed in writing by the Parties.
     Further, MediGene may in its discretion determine to pay any such Disputed
     Amount and in the event amounts are finally determined not to be due by
     MediGene, Atrix shall repay, without interest, such excess amounts
     determined not to be due; or

          (b) Upon the occurrence of any material misrepresentation or omission
     in any Royalty Statement, which misrepresentation or omission is caused by
     MediGene's willful misconduct, gross negligence or bad faith.

     Section 19.04. TERMINATION BY MEDIGENE. MediGene may terminate its license
to the Product for a country in the Territory prior to the expiration of the
Term in the event that MediGene determines in good faith that the Purchase Price
for the Product is not commercially viable with respect to such country in the
Territory in accordance with Section 8.02(b).

     Section 19.05. REMEDIES. All of the non-breaching Party's remedies shall be
cumulative, and the exercise of one remedy hereunder by the non-defaulting Party
shall not be deemed to be an election of remedies. These remedies shall include
the non-breaching Party's right to sue for damages for such breach without
terminating this Agreement.

     Section 19.06. EFFECT OF TERMINATION.

          (a) Subject to Section 19.06(d), upon termination of this Agreement by
     Atrix pursuant to Sections 19.02 or 19.03, (i) MediGene shall have no right
     to practice within the Atrigel(R) Patent Rights or use any of the
     Atrigel(R) Technology, (ii) all rights, title or interest in, or other
     incidents of ownership under, the Atrigel(R) Technology and the Marks shall
     revert to and become the sole property of Atrix, (iii) MediGene shall
     reimburse Atrix for costs and expenses reasonably incurred or committed to
     by Atrix prior to the effective date of such termination and for which
     MediGene is otherwise obligated to reimburse Atrix pursuant to this
     Agreement in connection with the activities performed by Atrix prior to the
     effective date of such termination consistent with the budget mutually
     agreed to by the Parties and approved by MediGene in accordance with
     Section 2.02, provided that Atrix shall use commercially reasonable efforts
     to minimize the such costs and expenses between the termination notice date
     and the date of termination, and (iv) MediGene shall grant to Atrix an
     irrevocable, non-exclusive, royalty-free license, with the right to
     sublicense, to the Clinical Documentation, the Results and the Marketing
     Authorizations and make any required filings with the Competent Authorities
     to the extent necessary and sufficient to market and sell the Product in
     the Territory.

          (b) Upon termination of this Agreement by MediGene pursuant to Section
     19.02(a), MediGene shall receive an irrevocable, non-exclusive,
     royalty-free license, with the right to sublicense, to Manufacture, market,
     advertise, promote, distribute, offer for sale, sell and import the Product
     in the Territory. Upon termination of this Agreement by MediGene pursuant
     to Section 19.02(b), the following shall occur: (i) MediGene shall have no

     Technology, and (ii) all rights, title or interest in, or other incidents
     of ownership under, the Atrigel(R) Technology and the Marks shall revert to
     and become the sole property of Atrix.

          (c) Upon termination by Atrix under Sections 19.02 or 19.03 or by
     MediGene under Sections 19.02(b) or 19.04, the following shall occur:

               (i) Except as otherwise provided in this Agreement, all
     applicable licenses granted to MediGene shall terminate immediately,
     including the rights granted to MediGene pursuant to Sections 3.02 and
     3.03, and MediGene shall have no further rights to the Product subject to
     MediGene's option to sell off existing inventory of Product and distribute
     existing inventory of Demonstration Samples for six (6) months after the
     termination date under subsection (ii) hereof, and MediGene shall not,
     either directly or indirectly, use or permit the use of the same or of the
     documentation relating to the Product, except to sell off existing
     inventory under subsection (ii) hereof;

               (ii) MediGene, at its option, may sell off any existing inventory
     of Product and utilize the Demonstration Samples during a period not to
     exceed six (6) months following such termination. If MediGene chooses this
     option, MediGene shall:

                    (A) within thirty (30) days of issuance of a notice of
               termination by any Party, notify Atrix that it intends to sell
               off existing inventory of Product and utilize the Demonstration
               Samples as provided in this Agreement;

                    (B) continue to comply with its payment obligations to Atrix
               under Article IV;

                    (C) continue to sell off existing inventory of Product and
               utilize the Demonstration Samples for six (6) months after the
               notice of termination but at the expiration of the six (6)
               months, at Atrix's election, either (1) sell all existing
               inventory of Product and Demonstration Samples to Atrix or (2)
               destroy all remaining inventory of Product and Demonstration
               Samples in accordance with Applicable Law, providing Atrix with
               proof of destruction in writing sufficient to comply with
               Applicable Laws; provided that in either case, Atrix shall pay to
               MediGene, the full amount of the actual cost paid by MediGene to
               Atrix for such remaining inventory of Product and Demonstration
               Samples. If MediGene sells any inventory of Product or
               Demonstration Samples to Atrix pursuant to this subsection, it
               shall warrant that such inventory of Product and Demonstration
               Samples has been stored in compliance with all Applicable Laws,
               has not been adulterated and has otherwise been maintained
               according to the requirements of Applicable Laws and Marketing
               Authorizations;

                    (D) if MediGene notifies Atrix that MediGene does not intend
               to sell off any existing inventory of Product and utilize the
               Demonstration Samples, MediGene shall, at Atrix's election,
               either (1) sell all existing


                                       46



               inventory of Product and Demonstration Samples to Atrix or (2)
               destroy all remaining inventory of Product and Demonstration
               Samples in accordance with Applicable Law, providing Atrix with
               proof of destruction in writing sufficient to comply with
               Applicable Laws; provided that in either case, Atrix shall pay to
               MediGene, the full amount of the actual cost paid by MediGene to
               Atrix, for such remaining inventory of Product and Demonstration
               Samples. If MediGene sells any inventory of Product or
               Demonstration Samples to Atrix pursuant to this subsection, it
               shall warrant that such inventory of Product and Demonstration
               Samples has been stored in compliance with all Applicable Laws,
               has not been adulterated and has otherwise been maintained
               according to requirements of Applicable Laws and Competent
               Authorities; and

                    (E) any sales of Product or Demonstration Samples made by
               MediGene to Atrix pursuant to this Section 19.06 shall be made by
               MediGene within thirty (30) days of the end of the time period
               specified by Section 19.06(c)(ii) and shall be shipped to Atrix
               appropriately packaged and stored. All transportation costs in
               connection with such sale, including without limitation,
               insurance, freight and duties, shall be shared equally by
               MediGene and Atrix. Amounts owed by Atrix to MediGene pursuant to
               this Section 19.06(c) for the Product or Demonstration Samples
               shall be paid by Atrix within ten (10) days after receipt by
               Atrix of an appropriately detailed invoice from MediGene for the
               amount so owing to it by Atrix under this subsection.

          (d) Except as otherwise provided in this Agreement, 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 3.04, 14.08, 14.09 and Articles XII, XV, XVII
     and XX and this Article IX shall survive expiration or termination of this
     Agreement.

          (e) Subject to the provision of Section 19.07, 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.

     Section 19.07. LICENSE FOLLOWING EXPIRATION. After expiration of the
Royalty Term, and upon request by MediGene, Atrix shall continue to sell the
Product to MediGene upon terms mutually agreeable to the Parties pursuant to a
separate supply agreement to be negotiated in good faith between the Parties.

                                  MISCELLANEOUS

     Section 20.01. NO-SOLICITATION. During the Term of this Agreement, neither
Party nor its Affiliates (collectively, the "Initiating Group") shall, directly

director or employee of the other Party or its subsidiaries or controlled
Affiliates (collectively, the "Other Group") with whom the Initiating Group has
contact in connection with, or who otherwise is known by the Initiating Group to
participate in, the transactions contemplated by this Agreement. The Initiating
Group shall not be precluded from hiring any such person who has been terminated
by the Other Group prior to commencement of employment discussions between such
person and the Initiating Group or its representatives. "Solicitation" shall not

indicated in this Agreement, each Party shall use commercially reasonable
efforts to perform its responsibilities under this Agreement. As used herein,
the term "commercially reasonable efforts" means, unless the Parties agree
otherwise, those efforts consistent with the exercise of prudent scientific and
business judgment, as applied to other products of similar scientific and
commercial potential within the relevant product lines of the Parties.

     Section 20.03. ASSIGNMENT. Except as expressly provided hereunder, neither
this Agreement nor any rights or obligations hereunder may be assigned or
otherwise transferred by either Party without the prior written consent of the
other Party (which consent shall not be unreasonably withheld); provided,
however, that either Party may assign this Agreement and its rights and
obligations hereunder without the other Party's consent (a) in connection with
the transfer or sale of all or substantially all of the business of such Party
to which this Agreement relates to another Party, whether by merger, sale of
stock, sale of assets or otherwise, or (b) to any Affiliate. Notwithstanding the
foregoing, any such assignment to an Affiliate shall not relieve the assigning
Party of its responsibilities for performance of its obligations under this
Agreement. The rights and obligations of the Parties under this Agreement shall
be binding upon and inure to the benefit of the successors and permitted assigns
of the Parties. Any assignment not in accordance with this Agreement shall be
void.

     Section 20.04. FORCE MAJEURE. Neither Party shall be held liable or
responsible to the other Party nor be deemed to have defaulted under or breached
this Agreement for failure or delay in fulfilling or performing any term of this
Agreement when such failure or delay is caused by or results from causes beyond
the reasonable control of the affected Party, including, but not limited to,
fire, floods, embargoes, war, acts of war (whether war be declared or not),
insurrections, riots, civil commotions, strikes, lockouts or other labor
disturbances, acts of God or acts, omissions or delays in acting by any
governmental authority or the other Party, or for any other reason which is

provided that the Party whose performance is delayed or prevented shall continue
to


                                       48



use good faith diligent efforts to mitigate, avoid or end such delay or failure
in performance as soon as practicable.

     Section 20.05. GOVERNING LAW. This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of Delaware,
USA, except that no conflict of laws provision shall be applied to make the laws
of any other jurisdiction applicable to this Agreement.

     Section 20.06. WAIVER. Except as specifically provided for herein, the
waiver from time to time by either of the parties of any of their rights or
their failure to exercise any remedy shall not operate or be construed as a
continuing waiver of same or of any other of such Party's rights or remedies
provided in this Agreement.

     Section 20.07. SEVERABILITY. In case any provision of this Agreement shall
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby. Any provision of this Agreement held invalid or unenforceable in part
or degree will remain in full force and effect to the extent not held invalid or
unenforceable.

 I. AMENDMENT OF THE COLLABORATION, LICENSE AND SUPPLY AGREEMENT EFFECTIVE APRIL
    4, 2001 (THE "AGREEMENT") BETWEEN ATRIX LABORATORIES, INC. ("ATRIX") AND
         MEDIGENE AKTIENGESELLSCHAFT ("MEDIGENE") CONCERNING AE EXCHANGE

As provided by Section 20.12 of the Agreement, Atrix and MediGene with effect as
of September 12, 2002 amend the Agreement as set out below:

Section 10.04 of the Agreement as currently in effect is deleted and replaced by
the following:

          "Section 10.04 ADVERSE EVENT REPORTING AND PHASE IV SURVEILLANCE.

     (a) In order to enable MediGene to meet its legal requirements regarding
adverse event reporting, Atrix shall collect from all of its license partners
other than MediGene having a license for the Product any safety information (the
"Safety Information"). The term "Safety Information" shall be including, but not
limited to (i) all serious adverse events (as defined by ICH E2A) ("SAE") known
from all sources (spontaneous reporting, clinical studies, literature,
regulatory authorities and compassionate use) and (ii) all non serious adverse
reactions from spontaneous reporting and literature.

     Any such Safety Information shall be submitted to MediGene in the form
developed by the Council for International Organizations of Medical Sciences
standard ("CIOMS Form") by fax. The Parties will, by separate mutual written
agreement, define further requirements for the data and information which shall
be given by Atrix in the CIOMS Form. The Safety Information provided in the
CIOMS Form shall be transmitted to MediGene (i) within [**] calendar days in
case of SAE, and (ii) in all other cases not regarding any SAE, within [**]
calendar days after first knowledge of the respective license partner about the
Safety Information. All Safety Information to be sent to MediGene shall be sent
attention to the pharmacovigilance officer of MediGene.

     MediGene shall have the right to ask Atrix for additional information about
these reports. The queries will be sent to Atrix by e-mail or fax; Atrix shall
answer within [**] calendar days. Atrix shall ensure, that the requested
information or any other follow-up information will be included into the CIOMS
Form by the respective license partner within [**] calendar days after first
knowledge of the additional information by the respective license partner.

     In case license partners conduct clinical trials with regard to the
Product, Atrix shall ensure that the respective license partner will without
delay provide Atrix with lists containing non serious adverse events from the
clinical studies every three months. Atrix will forward these lists to MediGene
within reasonable time.

     In case Atrix exercises its rights to co-market the Product within the
Territory pursuant to Section 13.01 of the Agreement, Atrix shall have the same
responsibility as the other license

- ----------
**   Confidential Treatment Requested.


                                        1



partners to provide Safety Information, including lists on non serious adverse
events from clinical studies with regard to the Product marketed by Atrix.

     If Atrix exercises its right to co-market as set forth in Section 13.01
then, upon the occurrence of any adverse event relevant for reporting as Safety
Information according this provision (an "AE"), the Parties shall promptly meet
in person or by telephone, as appropriate, to discuss and determine how to
mutually handle and resolve any issues relating to or arising from any such AE.

     (b) In order to enable Atrix to meet its legal requirements regarding
adverse event reporting, MediGene shall report to Atrix any Safety Information
related to the use of the Product in the Territory and known to MediGene,
including, but not limited to (i) all SAE known from all sources (spontaneous
reporting, clinical studies, literature, regulatory authorities and
compassionate use) and (ii) all non serious adverse reactions from spontaneous
reporting.

     Any such Safety Information shall be submitted by MediGene to Atrix in a
CIOMS Form by fax. The Safety Information provided in a CIOMS Form shall be
transmitted to Atrix (i) in case of SAE within [**] calendar days, and (ii) in
all other cases not regarding SAE, within [**] calendar days, after first
knowledge about the Safety Information. All Safety Information to be sent to
Atrix shall be sent attention to the pharmacovigilance officer of Atrix.

     Atrix will have the right to ask MediGene for additional information about
these reports. The queries will be sent to MediGene by e-mail; MediGene will
answer within [**] calendar days. MediGene shall ensure, that the requested
information or any other follow-up information will be included into the CIOMS
Form within [**] calendar days after first knowledge of the additional
information.

     (c) If the report of an AE causes a Competent Authority to request labeling
revision as a result of an AE or that a Phase IV surveillance program be
conducted, then the Parties shall promptly enter into discussions and shall
mutually agree on all of the material terms and conditions of such labeling
revision or Phase IV surveillance program; provided, however the costs of such
labeling revision or Phase IV surveillance program shall be borne [**] by
MediGene and [**] by Atrix. MediGene shall have the authority to make the final
decision with regard to any labeling revisions provided that MediGene will
consider, in making its decision, the effect any such labeling revisions will
have on the marketing and sale of the Product outside the Territory. MediGene
agrees that should Applicable Laws require that any such interim data and
results from such Phase IV surveillance programs be prepared in written form,
MediGene shall comply with such requirements and provide all such information in
writing to MediGene and the Competent Authorities in accordance with Applicable
Laws. MediGene further agrees that Atrix shall have the right to incorporate,
refer to and cross-reference such results and underlying data in any regulatory
filing or any other filing or requirement Atrix is required to undertake with
respect to the Product. Atrix agrees that MediGene shall have the right to
incorporate, refer to and cross-reference such results and underlying data in
any regulatory filing or any other filing or requirement MediGene is required to
undertake with respect to the Product in the Territory."

The Agreement remains otherwise unaltered.

"Second Amendment"), is made by and between Atrix Laboratories, Inc., a Delaware
corporation having offices at 2579 Midpoint Drive, Fort Collins, CO, 80525-4417
("Atrix"), and MediGene AG, a German corporation having offices at Lochhamer
Strasse 11, Planegg/Martinsried, Germany ("MediGene") as of this 22nd day of
December, 2003. Atrix and MediGene are sometimes referred to collectively herein
as the "Parties" or singly as a "Party."

     WHEREAS, the Parties entered into that certain Collaboration, License and
Supply Agreement dated as of April 4, 2001, as subsequently amended by that
certain First Amendment to Collaboration, License and Supply Agreement and Stock
Purchase Agreement effective as of September 12, 2002 (collectively, the
"Agreement"); and

     WHEREAS, MediGene intends to grant a sublicense under the Agreement to
YAMANOUCHI U.K. Limited and to enter into a Distribution, Sublicense and Supply
Agreement in connection therewith; and

     WHEREAS, the Parties therefore desire to further amend the Agreement as set
forth herein.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth in the Agreement and as hereinafter set forth, and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
Parties agree as follows:

     1. The definition of each of "cGMP", "First Commercial Sale", "Governmental

time)."

     "First Commercial Sale" means (a) with respect to a country in the
Territory, the first sale for use, consumption or resale of each Product by
MediGene or YAMANOUCHI or its sublicensees in such country and (b) with respect
to the Territory, the First Commercial Sale in any country within the Territory.
A sale to an Affiliate shall not constitute a First Commercial Sale unless the
Affiliate is the end user of the Product."

     "Governmental Approval(s) " means all permits, licenses and authorizations,
including but not limited to, import permits, Marketing Authorizations, and
Pricing and Reimbursement Approvals required by any Competent Authority as a
prerequisite to the Manufacture, packaging, marketing or selling of the Product

     "Marketing Authorization" means all necessary and appropriate regulatory
approvals, including but not limited to, variations thereto, to put the Product
on the market in a particular country in the Territory."

     "Net Sales" means the [**].

     Components of Net Sales shall be determined in the ordinary course of
business in accordance with historical practice and using the accrual method of
accounting in accordance with GAAP.

     In the event MediGene or its Affiliates or YAMANOUCHI or its Affiliates,
subcontractors or sublicensees transfers Product to a Third Party in a bona fide
arm's length transaction, for consideration, in whole or in part, other than
cash or to a Third Party in other than a bona fide arm's length transaction, the
Net Sales price for such Product shall be deemed to be the standard invoice
price then being invoiced by MediGene or its Affiliates or YAMANOUCHI or its
Affiliates, subcontractors or sublicensees in an arm's length transaction with
similar customers. In the event that MediGene or its Affiliates or YAMANOUCHI or
its Affiliates, subcontractors or sublicensees includes one or more Product as
party of a bundle of products, MediGene agrees not to, and agrees to cause its
Affiliates, YAMANOUCHI and YAMANOUCHI's Affiliates, subcontractors and
sublicensees not to, offer or sell any such Product as a loss leader (i.e. sold
at less than the invoice price at which any such Product is sold when not part
of a bundle of products) in determining the price of the bundled products."

     "Royalty Term" means the period of time commencing on the First Commercial
Sale of each Product in any country in the Territory and [**]."

     "Territory" means Albania, Andorra, Armenia, Austria, Azerbaijan, Belarus,

collectively, as the case may be, the countries in the Territory excluding the
Major Countries."

a written notification of a Negative Launch Decision with respect to a Product
for a specific country within [**] after notice of grant of both the Marketing
Authorization and the Pricing and Reimbursement Approval in such country is
received by MediGene, MediGene shall be deemed to have notified Atrix of a
Positive Launch Decision with regard to such Product and such country on the
business day immediately following expiry of such [**] period. MediGene shall
make any Launch Decision by assessing, in good faith, the case for or against
launching the respective Product in the respective country, such assessment
taking into account the following: [**]. Where a Negative Launch Decision has
been notified to Atrix MediGene shall provide Atrix within [**] of the expiry of
the [**], and subject to obligations of confidentiality reasonably acceptable to
MediGene, copies of all relevant information and documents on which the Negative
Launch Decision was made.

     (II) In case of a Negative Launch Decision Atrix shall be entitled to
request that such Negative Launch Decision be assessed by an independent expert
Third Party appointed by MediGene and acceptable to Atrix (the "Independent
Assessor"), such request to be made in writing delivered to MediGene no later
than [**] after receipt of the respective Negative Launch Decision by Atrix. The
Independent Assessor shall assess the Negative Launch Decision of MediGene
within reasonable time and shall promptly and simultaneously notify Atrix and
MediGene of the result in writing of this assessment. The Independent Assessor
shall assess the Negative Launch Decision impartially having regard to and
considering the criteria referred to above under Section 3.02(d)(iii)(I).

     (III) If the Independent Assessor determines that the Negative Launch
Decision of MediGene is on balance correct, or if Atrix does not exercise its
right to request an assessment of the Negative Launch Decision by an Independent
Assessor within [**] after receipt of the Launch Decision by Atrix, then
MediGene shall no longer be obliged, but shall remain exclusively entitled, to
launch the respective Product in the respective country.

     (IV) In case of a Positive Launch Decision, Section 3.02(d)(iv) shall
apply, whereby the relevant date for the calculation of time in (iv) below
("Trigger") shall be the date the Positive Launch Decision is either made or
deemed to be made by MediGene.

     (V) If the Independent Assessor notifies MediGene of his determination that
the Negative Launch Decision of MediGene is not correct, Section 3.02(d)(iv)
shall apply, whereby the relevant date for the calculation of time in (iv) below
("Trigger") shall be the date of [**].

     (iv) If MediGene has not undertaken commercially reasonable efforts to
     begin Distribution and Marketing of the Product (A) in a Major Country
     within [**] following the Trigger, as defined above, for the Product in
     that Major Country and (B) in a Non-Major Country within [**] following the
     Trigger, as defined above, for the Product for that Non-Major Country;
     provided that in each case of (A) and (B) above Atrix and MediGene have
     available and have delivered (and YAMANOUCHI having ordered) Launch
     Quantities of the Product, then, and at any time such event occurs, and
     upon each such occurrence, the following shall occur with respect to that
     Product not so distributed and marketed, in that Major Country within such
     [**] or, as the case may be, in that Non-Major Country within such [**]:

     (I) Atrix shall have the right upon [**] written notice to MediGene to
terminate the Agreement with respect to that Product in that specific country
and, upon such termination, such country shall no longer be included in the
Territory for such Product, and

     (II) Atrix shall have the right to grant a license to a Third Party to
market and distribute that Product in such country, provided that the terms of
such license are no more favorable to the Third Party, in any material respect,
than those set forth in this Agreement, and subject to adjustments to reflect
the fact that the licensee under such licenses will not have the right to market
and distribute the Product in the entire Territory; and

     (III) MediGene shall, or shall procure that YAMANOUCHI and its sublicensees
will: (1) promptly transfer to Atrix the Marketing Authorizations, and other
Governmental Approvals where applicable, relating to such Product in such
country and (2) make any mandatory filings with Competent Authorities in respect
thereof, and (3) grant to Atrix an irrevocable, non-exclusive, royalty-free
license, with the right to sublicense, to use any Clinical Documentation to the
extent necessary and sufficient for Atrix, its Affiliates and sublicensees to
use the Governmental Approvals and to market and distribute such Product in such
country.

     (v) For the avoidance of doubt, notwithstanding the foregoing, MediGene
     shall in no event be entitled to unreasonably refrain from or delay any
     submission for any Marketing Authorization or Pricing and Reimbursement
     Approval for the Product(s).

     (vi) The rights and obligations under this Section 3.02(d) shall be
     cumulative with the other rights and obligations under this Agreement and
     shal1 not apply with respect to any

     "(e) Sublicense to YAMANOUCHI. It is agreed that MediGene may grant a
sublicense under the Atrigel(R) Technology and the Atrix Marks to YAMANOUCHI
U.K. Limited ("YAMANOUCHI") in accordance with a Distribution, Sublicense and
Supply Agreement substantially in the form attached hereto as Exhibit I (the
"Sublicense"). Neither Party shall be entitled to terminate this Agreement under
Section 19.02(b) due to the other Party's failure to comply with the terms of
this Agreement if such failure is caused by a conflict between the terms and
conditions of the Sublicense and this Agreement that makes it impossible for
such Party to perform its obligations under this Agreement (the "Conflict");
provided that notwithstanding the foregoing, a Party's right to terminate this
Agreement pursuant to its terms and conditions if the other Party does not
comply with its financial obligations under this Agreement shall not be excluded
or otherwise affected by this provision. In the event that after the date of
execution of the Sublicense a Party determines that there is a Conflict, such
Party shall provide written notice of such occurrence to the other Party and the
Parties will attempt to negotiate in good faith an amendment to this Agreement
so that no such Conflict exists. If such amendment is not executed within thirty
(30) days following a Party's receipt of such notice the Parties will have all
of their respective rights and obligations under this Agreement, except for the
right to terminate this Agreement pursuant to Section 19.02(b); provided that
notwithstanding the foregoing, a Party's right to terminate this Agreement
pursuant to its terms and conditions if the other Party does not comply with its
financial obligations under this Agreement shall not be excluded or otherwise
affected by this provision.

     8. Section 3.03 of the Agreement is hereby renumbered as Section 3.03(a)
and the following is hereby added as a new Section 3.03(b):

     "(b) Without the prior written consent of Atrix, MediGene shall market and
distribute the Products in the Territory under the Atrix Marks. Notwithstanding
the foregoing, MediGene shall be entitled, without the consent of Atrix, to
market and distribute the Product under a YAMANOUCHI Trade Mark rather than an
Atrix Mark if an objection to the use of an Atrix Mark has been lawfully raised
by (i) a Competent Authority in the Territory; or (ii) a Third Party with
enforceable trade mark rights having seniority to those of the Atrix Marks."

     9. Section 3.04(b) of the Agreement is hereby deleted in its entirety and
the following are hereby added as Sections 3.04(b), 3.04(c), 3.04(d) and
3.04(e):

or discoveries made in connection with any leuteinizing hormone releasing
hormone (LHRH) or a structurally related derivative or structurally related
analog thereof, whether agonist or antagonist, whether naturally-occurring or
synthetic, used for treatments outside the Field, which do not relate to the
Atrigel(R) Technology or the Product, but are specifically only made during and
as a direct result of either MediGene's or YAMANOUCHl's or other sublicensee's
work in connection with this

Agreement, shall be jointly owned by Atrix, MediGene, and YAMANOUCHI or the
applicable sublicensee, including any patentable inventions (the "Program
Technology").

     (c) Subject to Section 3.04(e), each of Atrix and MediGene grant to the
other and to YAMANOUCHI, and MediGene shall procure that YAMANOUCHI and any
other sublicensee, grants to Atrix a non-exclusive, irrevocable, worldwide,
royalty-free, perpetual license, including the right to grant sublicenses to
Affiliates, to make and use the Program Technology for all research purposes
(consistent with the purpose and intent of this Agreement) other than the sale
or manufacture for sale of products or processes; provided that if any Party
desires to provide a Third Party a sublicense to manufacture, use, market or
sell any product based on the Program Technology, then such Party shall grant to
the other Party a right of first negotiation according to Section 3.04(d) with
respect to such product.

     (d) For a period of thirty (30) days following the receipt of notice from
any Party (the "Notifying Party") of its intention to grant a sublicense as set
out in Section 3.04(c), the other Party(ies) (the "Notified Party") shall have
the first right to negotiate binding material terms for a definitive license
agreement for such a product. In the event (i) the Notified Party does not
determine within such thirty (30) day period to pursue a license for such a
product, or (ii) the Parties are unable to reach agreement on binding material
terms of such a license within such thirty (30) day period, or (iii) if the
Parties have reached agreement on binding material terms of such a license
within such thirty (30) day period, but are unable to enter into a definitive
agreement within ninety (90) days following the written notice from the
Notifying Party, which period may be extended upon the mutual agreement of the
Parties, the Notifying Party shall have no further obligation to the Notified
Party under this Section 3.04(d. If the Parties cannot agree to the terms of
such license, then the Notifying Party may enter into an agreement with a Third
Party, provided that the terms of the agreement are no more favorable to the
Notifying Party, in any material respect (individually or in the aggregate),
than those last proposed in writing by the Notified Party. The rights of
Notified Party under this Section 3.04(d) shall be limited to those countries in
the Territory for which Notified Party retains a license under this Agreement as
of the date written notice is received under this Section 3.04(d) by either
Party, as applicable. If Notifying Party enters into an agreement with a Third
Party under this Section 3.04(d), Notifying Party shall notify Notified Party of
this fact within four (4) weeks after the date the agreement is entered into.
Notified Party shall then have the right to appoint an appropriate independent
person, reasonably acceptable to Notifying Party, having sufficient experience
in licensing matters, which person shall execute a confidentiality agreement in
such form as is reasonably satisfactory to Notifying Party, to examine the terms
and conditions of such agreement to determine that the terms thereof are no more
favorable to Notifying Party, in any material respect (individually or in the
aggregate), than those last proposed in writing by Notified Party. Such
determination shall be made within six (6) weeks after the date Notifying Party
provides notice to Notified Party that it has entered into such an agreement
with a Third Party. In the event the terms are more favorable to Notifying Party
then the Notifying Party shall terminate the Third Party license immediately.

     (e) Any developments, inventions or discoveries made in connection with any
leutenizing hormone releasing hormone ("LHRH") or a structurally related
derivative or structurally related analog thereof, whether agonist or
antagonist, whether naturally-occurring or synthetic, used for treatments
outside the Field, which do not relate to the Atrigel@ Technology or the
Product, but which were made during and as a direct result of either MediGene's

accepted business practices devoting the same level of efforts as it devotes to
its own products of comparable market potential. "Comparable market potential"
shall be fairly determined by MediGene in good faith and shall be based upon
market size, price, present and future competition and general marketing
parameters. Each Party shall promptly advise the other Party, and MediGene will

     (a) Atrix shall Manufacture the Product in accordance with the
     Specifications. Any modifications of the Specifications require Atrix's,
     MediGene's and YAMANOUCHI's written approval, which will not unreasonably
     be withheld or delayed. If MediGene or YAMANOUCHI should come to the
     conclusion that a modification is required, MediGene will, or will cause
     YAMANOUCHI to, submit a proposal for modification to Atrix. If Atrix or
     YAMANOUCHI, as applicable, disapproves, Atrix, MediGene and YAMANOUCHI will
     amicably determine the further measures to be taken and pending such
     determination provided that the amendment sought is mandatory pursuant to

     (a) Not later than six (6) months following submission of the relevant NDA
     or other equivalent applicable regulatory filing on a country by country
     basis, MediGene will provide Atrix with a twelve (12) month forecast of
     MediGene's requirement of each Product, on a Product by Product basis,
     including Demonstration Samples, and on a country by country basis as
     follows (the "Initial Forecast"), unless agreed otherwise on a case by case
     basis in writing:

     (i) For the first twelve (12) month period covered by the Initial Forecast
for each Product, MediGene shall provide quarterly, no less than forty- five
(45) days prior to the beginning of each calendar quarter a further twelve month
forecast. Said requirements will be based on standard production planning
parameters including but not limited to sales forecasts, sales demand forecasts,
promotional forecasts, inventory requirements, and the like. The twelve (12)
month forecast will be stated in monthly requirements. The second two (2)
quarters of the twelve (12) month forecast will be total requirement by stock
keeping unit and will be stated as quarterly requirements. The first three (3)
months of the twelve (12) month forecast will be firm orders to purchase. The
second three (3) months will be allowed to be flexed from the previous forecast
by plus or minus [**] per month until fixed by the subsequent forecast; provided
that the aggregate adjustment from the quantity set forth in the previous
forecast for such three (3) month period shall not exceed [**] in aggregate
during that three (3) month period. [**].

     Notwithstanding the above, and in respect of the One Month Product and
Three Month Product in Germany only, MediGene will provide Atrix with the
Initial Forecast as soon as reasonably possible following the date of execution
of the Sublicense and Atrix will use reasonable efforts to fulfill purchase
orders contained in such Initial Forecast.

     (ii) After the first twelve (12) months MediGene will provide to Atrix a
rolling twelve (12) month forecast for each Product with the first three (3)
months of the rolling twelve (12) month forecast a firm order to purchase. Each
order in the rolling twelve (12) month forecast shall be provided monthly, no
less than twenty (20) days prior to the beginning of each month. All orders will
be for full batch quantities [**]. Notwithstanding the foregoing, for the first
twelve (12) months after launch of each Product the Parties agree to use
commercially reasonable efforts to cause each order to be for full batch
quantities, but acknowledge and accept that during such twelve (12) month period
orders may be for less than full batch quantities.

     (b) It is understood that Atrix will not maintain Product or Demonstration
     Sample inventory in excess of the forecast, but will produce Product or
     Demonstration Sample upon receipt of that portion of MediGene's forecasts
     that constitute firm orders to purchase. The above periods whether fixed or
     flexible will be adjusted based upon existing lead times at time of start
     up.

     (c) MediGene agrees to purchase a sufficient amount of Product to enable
     MediGene to carry sufficient inventory to allow for fluctuations in sales
     demand so as to allow Atrix reasonable lead time to meet increased demand.
     Atrix will use commercially reasonable efforts to meet any increase in
     demand in excess of the allowed adjustment, but will not be obligated to do
     so beyond [**] of MediGene's forecast for the relevant twelve (12) month
     period subject to Section 7.06(c). All forecasts will be made by MediGene
     to Atrix in good faith based upon standard commercial parameters. From time
     to time after the Effective Date, the Parties shall consider whether, in
     light of market demand, manufacturing capacity, inventory levels and other
     pertinent factors, to revise the schedule for delivery of forecasts and, if
     appropriate, negotiate in good faith to revise such schedule.

     (d) The Launch Quantity of the Product when delivered to the common carrier
     shall not have an expiration date of less than [**] from the date of such
     delivery, provided (a) Product other than the Launch Quantity shall not
     have an expiration date of less than [**] once real time stability data is
     submitted by Atrix to the respective Competent Authority, and/or (b) as the
     Parties may otherwise agree in writing on a case by case basis.

     (e) In the event MediGene does not receive a Marketing Authorization in a
     specified country in the Territory, but Atrix nevertheless has Manufactured
     the Launch Quantity of the Product for sale in such country in the
     Territory, the Atrix Manufacturing Cost attributable to the Manufacture of
     the Launch Quantity for sale in such country shall be [**]."

Marks, or if Atrix declines responsibility for the maintenance of such rights,
Atrix shall provide reasonable prior written notice to MediGene in advance of
its intention to abandon or decline responsibility, and MediGene (or at request
of MediGene its sublicensees) shall have the right, but not the obligation, to
prepare, file, prosecute, and maintain any such rights and such rights shall be
transferred to MediGene (or its sublicensees if requested by MediGene).

     (b) Atrix shall, at Atrix's expense and to the extent commercially
reasonable, prosecute through to grant, maintain and protect the Atrigel Patent
Rights in full force and effect in all countries in the Territory where such
rights exist or could exist in the future. In the event that Atrix desires to or
does abandon one or more of the Atrigel Patent Rights, or if Atrix declines
responsibility for the maintenance of such rights, Atrix shall provide
reasonable prior written notice to MediGene in advance of its intention to
abandon or decline responsibility, and MediGene (or its sublicensees upon
request by MediGene) shall have the right, but not the obligation, to prepare,
file, prosecute, and maintain any such rights and such rights shall be
transferred to MediGene (or its sublicensees if requested by MediGene).

     (c) With regard to Section 3.04, Atrix, in its sole discretion, shall
determine whether or not to maintain and protect the Program Technology it
creates in accordance with Section 3.04, MediGene, in its sole discretion, shall
determine whether or not to maintain and protect the Program Technology it
creates in accordance with clause 3.04 and MediGene's sublicensees (if any) at
its sole discretion shall determine whether or not to maintain and protect the
Program Technology it creates in accordance with clause 3.04. Each Party, at the
reasonable expense of the creator, shall provide such assistance to the creator
as may be necessary to enable the creator of the Program Technology to maintain
the Program Technology. In the event that the creator of the Program Technology
does not wish to seek formal protection for or desires to or does abandon any
patent application or patent, or if such creator later declines responsibility
for such patent application or patent in respect of their Program Technology,
such creator shall provide reasonable prior written notice to the others of its
intention to abandon or decline responsibility, and the others shall have the
equal right at their own cost and expense, but not the obligation, to prepare,
file, prosecute, and maintain any such patent application or patent in respect
of such Program Technology and shall be entitled to the reasonable assistance
(at its own reasonable expense) of the creator. Notwithstanding who applies for
or maintains such protection the creator of the Program Technology shall not be
prevented from using such Program Technology pursuant to section 3.04(c).

     21. Section 11.02 of the Agreement is hereby deleted in its entirety and
replaced with the following:

     "(a) During the Term, each Party shall give prompt notice to the other of
any Third Party act which may infringe the Atrigel(R) Patent Rights or the Atrix
Marks in the Territory and shall cooperate with each other to terminate such
infringement without litigation. Atrix shall, at its sole expense, prosecute the
judicial or administrative proceedings against such Third Party infringement.
MediGene shall provide such assistance and cooperation to Atrix as may be
necessary to successfully prosecute any action against Third Party infringement
at Atrix's expense and may deduct the expenses thereof from any amounts payable
to Atrix under this Agreement.

     In the event Atrix fails to institute proceedings in the Territory against
any Third Party infringement of the Atrigel(R) Patent Rights and/or the Atrix
Marks within forty-five (45) days


                                       14



after notice given by either Party to the other of said Third Party
infringement, MediGene (or with MediGene's consent its sublicensees) may take
such action as it deems appropriate, including without limitation, the filing of
a lawsuit against such Third Party. In such event Atrix will provide such
assistance and cooperation to MediGene and its sublicensees as may be necessary,
at MediGene's (respectively its sublicensees') expense, and MediGene may deduct
all costs and expenses of such actions incurred by MediGene against any amount
payable to Atrix under this Agreement, and MediGene and/or its sublicensees may
retain all amounts awarded in such action.

     (b) With respect to patented Program Technology and pursuant to Section
3.04(d), in the event any patent included in the Program Technology is infringed
by a Third Party, the Party (the "Enforcer") responsible for prosecution and
maintenance of the applicable Program Technology under Section 11.01(c) (subject
to Section 3.04) shall have the right to bring and control such action or
proceeding, using counsel reasonably acceptable to the Parties, and shall be
provided by the other Party(ies), at its own cost and expense, with such
assistance and cooperation as may be reasonably necessary to successfully
prosecute any action against such Third Party. In the event the Enforcer fails
to institute proceedings against any Third Party infringement of the Program
Technology within the earlier of (i) the time period required under Applicable
Laws or (ii) forty-five (45) days after notice given by either Party to the
other of said Third Party infringement, the other Party(s) may take such action
as it deems appropriate, including without limitation, the filing of a lawsuit
against such Third Party. In such event the Enforcer will provide such
assistance and cooperation to the other Party as may be necessary, at the other
Party's expense.

     (c) Neither Atrix nor MediGene may settle an action or proceeding against
an infringer related to the Program Technology, and MediGene may not settle an
action or proceeding against an infringer related to Atrigel(R) Technology, with
respect to an infringement without the written consent of the other Party. Such
consent shall not be unreasonably withheld or delayed, but may be withheld if
such settlement would materially and adversely affect the interest of such
Party, including Atrix's rights hereunder or Atrix's rights in the Atrigel(R)
Technology."

     22. Section 13.01 of the Agreement is hereby deleted in its entirety and
