                  are required by Competent Authorities to market [**] the
                  Product in the Territory then the Parties shall discuss the
                  design and budget of such clinical trials and tests and
                  MediGene shall conduct and pay all costs and expenses

                  avoidance of any doubt, MediGene shall make the final
                  determination as to the design of such clinical trials and
                  tests; provided that MediGene will consider the effect of such
                  designs on the marketing and sale of the Product outside the

                  fibrosis and MediGene elects to fund the development of such

                  discuss the design and budget of such development and MediGene
                  shall conduct and pay all costs and expenses associated with
                  the development of such Product with such indication in the
                  Territory. For the avoidance of any doubt, MediGene shall make
                  the final determination as to the design of such development
                  program; provided that MediGene will consider the effect of
                  such design on the marketing and sale of the Product outside
                  the Territory. Atrix shall diligently assist and support
                  MediGene in such development program and MediGene shall
                  reimburse Atrix for all costs and expenses incurred by Atrix
                  in supporting such development program, promptly upon receipt
                  of a reasonably detailed invoice setting forth such costs and
                  expenses in accordance with the budget mutually agreed to by
                  the Parties and approved by MediGene.

         same terms and procedures as MediGene's right of first negotiation as
         set forth in Section 5.02 with respect to such product.

         Section 4.05. REPORTS.

                  (a) Reports. MediGene shall furnish to Atrix a quarterly
         written report showing in reasonably specific detail, on a Product by
         Product and country by country basis, (a) the calculation of Net Sales;
         (b) royalties payable in United States' Dollars, if any, which shall
         have accrued hereunder based upon Net Sales; (c) withholding taxes, if
         any, required by law to be deducted with respect to such sales; (d) the
         dates of the First Commercial Sales of any Product in any country in
         the Territory during the reporting period; and (e) the exchange rates
         used to determine the amount of United States' Dollars (collectively,
         the "Royalty Statement"). Royalty Statements shall be due as soon as
         possible, but in any event no later than sixty (60) days following the
         close of each calendar quarter.

                  (b) Exchange Rate; Manner and Place of Payment. All payments
         hereunder shall be payable in United States dollars. With respect to
         each quarter, whenever conversion of payments from any foreign currency
         shall be required, such conversion shall be made at the rate of
         exchange reported in The Wall Street Journal on the last business day
         of the applicable calendar quarter. All payments owed under this
         Agreement shall be made by wire transfer to a bank account designated
         by Atrix, unless otherwise specified in writing by Atrix.

                  (c) Late Payments. In the event that any payment, including
         contingent payments, due hereunder is not made when due, each such
         payment shall accrue interest from the date due at Prime Rate of
         Interest. The payment of such interest shall not limit Atrix from
         exercising any other rights it may have under this Agreement as a
         consequence of the lateness of any payment.

                  (d) Records and Audits. During the Term and for a period of
         two (2) years thereafter or as otherwise required in order for Atrix to
         comply with Applicable Law, MediGene shall keep complete and accurate
         records in sufficient detail to permit Atrix to confirm the
         completeness and accuracy of: (i) the information presented in each
         Royalty Statement and all payments due hereunder; (ii) the calculation
         of A&S and (iii) the calculation of Net Sales. MediGene shall permit an
         independent, certified public accountant reasonably acceptable to
         MediGene to audit and/or inspect those records of MediGene (including
         but not limited to financial records) that relate to Net Sales, Royalty
         Statements and A&S for the sole purpose of: (A) verifying the
         completeness and accuracy of the Royalty Statements; (B) verifying the
         calculation of the Net Selling Price, the calculation of Net Sales and
         the calculation of A&S and (C) to confirm Royalty payments and A&S
         expenditures for the Product for the previous year. Such inspection
         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





                                       15
   21

         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, 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

                                       16

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




                                       17
   23

         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 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;




                                       18
   24

                                    (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 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.

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 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,




                                       21
   27

         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.

         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





                                       22
   28

         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 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.

         Section 8.02. ADJUSTMENT TO PURCHASE PRICE/AUDIT.

                  (a) The Atrix Manufacturing Cost will be adjusted on a Product
         by Product and country by country basis annually commencing with the
         first day of the first calendar month twelve (12) months from the date
         of the First Commercial Sale of each Product (the "Adjusted Atrix
         Manufacturing Cost"). [**]:

                           (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 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, 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. 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.

                       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 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

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.

         Section 10.01. MARKETING AUTHORIZATION HOLDER. Unless otherwise
required by Applicable Laws and subject to the provisions of Sections 3.02 and
19.06(e), [**] shall be the holder of all Marketing Authorizations for each
country in the Territory. [**] will own and maintain the Marketing
Authorizations during the term of this Agreement. Each Party agrees that neither
it nor its Affiliates and any sublicensee will do anything to adversely affect a
Marketing Authorization.

         Section 10.02. MAINTENANCE OF MARKETING AUTHORIZATIONS. [**] agrees, at
its sole cost and expense, to maintain the Marketing Authorizations throughout
the Term of this Agreement, including obtaining any variations or renewals
thereof.

         Section 10.03. INTERACTION WITH COMPETENT AUTHORITIES.

                  (a) After execution of this Agreement, each Party shall
         provide to the other Party a copy of any significant correspondence
         regarding the Product in the Territory that it submits to or receives
         from Competent Authorities and/or the FDA, within ten (10) days of
         submission or receipt, as the case may be.

                  (b) In addition to the requirements set forth in Section
         2.02(c), MediGene shall provide Atrix with a copy of any significant
         correspondence regarding the Product that it submits to or receives
         from the Competent Authorities, within ten (10) days prior to the date
         of submission or within ten (10) days from receipt, as the case may be.

         Section 10.04. ADVERSE DRUG EVENT REPORTING AND PHASE IV SURVEILLANCE.

                  (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 facsimile of any

         adverse reaction, stating the full facts known to such Party, including
         but not limited to customer name, address, telephone number, batch, lot
         and serial numbers, and other information as required by Applicable
         Laws. For so long as MediGene has an exclusive license to market,
         promote and sell the Product in any country in the Territory for use in
         the Field, MediGene shall have full responsibility for (i) monitoring
         such adverse reactions; and (ii) data collection activities that occur
         between MediGene and the patient or medical professional, as
         appropriate, including any follow-up inquiries which MediGene deems
         necessary or appropriate.

                  If Atrix exercises its right to co-market as set forth in
         Section 13.01 then upon the occurrence of an ADE 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 ADE.

                  (b) In the event either Party requires information regarding
         adverse drug events with respect to reports required to be filed by it
         in order to comply with Applicable Laws, including obligations to
         report ADEs to the Competent Authorities, each Party agrees to provide
         such information to the other on a timely basis.

                  (c) The Parties agree to follow MediGene's standard operating
         procedure for reporting and identifying adverse drug reactions (the
         "SOP") 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 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.

         Section 10.05. COMMERCIAL SALE TESTING AND REPORTING. If, after the
date of First Commercial Sale in any country in the Territory, a Competent
Authority requires additional testing, modification or communication related to
approved indications of the Product, then the Parties shall design and MediGene
shall implement any such testing, modification or communication as shall be
mutually agreed upon by the Parties, and the costs shall be borne [**].

         Section 10.06. ASSISTANCE. Each Party shall provide reasonable
assistance to the other at the other's request, in connection with their
obligations pursuant to this Article X, subject to reimbursement of all of its
out-of-pocket costs by the requesting Party.

         Section 10.07. COMPLIANCE. MediGene and Atrix shall comply with all
Applicable Laws within the Territory as set forth in this Agreement, including
the provision of information by MediGene and Atrix to each other necessary for
Atrix and MediGene to comply with any applicable reporting requirements. Each
Party shall promptly notify the other Party of any comments, responses or
notices received from, or inspections by, the FDA, or other applicable Competent
Authorities, which relate to or may impact the Product or the Manufacture of the
Product or the sales and marketing of the Product, and shall promptly inform the
other Party of any responses to such comments, responses, notices or inspections
and the resolution of any issue raised by the FDA or other Competent
Authorities.

                             PATENTS AND TRADEMARKS

         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, provide such assistance as may be necessary to
         enable Atrix to comply with the administrative formalities necessary to
         maintain the Atrigel(R) Patent Rights and the Marks and to prosecute
         and obtain new patents related to the Atrigel(R) Technology. MediGene
         shall, at MediGene's expense, maintain and protect any trademark, logo,
         design and/or tradedress for the Product in those countries in the
         Territory for which MediGene retains a license pursuant to Section 3.02
         and to the extent commercially reasonable, other than the Marks.

                  (b) MediGene, to the extent commercially reasonable, shall
         maintain and protect the Program Technology in all countries in the
         Territory and Atrix, to the extent

         commercially reasonable, shall maintain and protect the Program
         Technology outside the Territory; provided however, that each Party
         shall provide such assistance as may be necessary to enable the other
         Party to comply with the administrative formalities necessary to
         maintain the Program Technology. In the event that a Party responsible
         for the 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 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





                                       33
   39

         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.

                  (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.

         Section 15.02. ATRIX INDEMNIFIED BY MEDIGENE. MediGene shall indemnify
and hold Atrix, its Affiliates, and their respective employees, directors and
officers, harmless from and against any Loss insofar as such Loss or actions in

distribution or promotion of the Product or the Demonstration Samples.

         Section 15.03. PROMPT NOTICE REQUIRED. No claim for indemnification
hereunder shall be valid unless notice of the matter which may give rise to such
claim is given in writing by the indemnitee (the "Indemnitee") to the persons
against whom indemnification may be sought (the "Indemnitor") as soon as
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.
The Indemnitor shall notify Indemnitee no later than sixty (60) days from such
notice of





                                       38
   44

its intention to assume the defense of any such claim. In the event the

Indemnitor full and free access to its books and records and otherwise fully
cooperate with the Indemnitor in connection with such action; provided that this
Indemnitee shall have the right fully to participate in such defense at its own
expense. The defense by the Indemnitor of any such actions shall not be deemed a
waiver by the Indemnitor of its right to assert a claim with respect to the
responsibility of the Indemnitor with respect to the Loss in question. The
Indemnitor shall have the right to settle or compromise any claim 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
Indemnitee of any issue, fact, allegation or any other aspect of the claim being
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
promptly defend, the Indemnitor shall not thereafter question the liability of
the Indemnitor hereunder to the Indemnitee for any Loss (including counsel fees
and other expenses of defense).

         the Territory; (iii) with regard to the Product, contact any of Atrix's

         (iv) contact the FDA or Competent Authorities or other entity located

otherwise specified in this Agreement, MediGene shall have the obligation and
responsibility for and shall make any and all necessary reports to the Competent
Authorities, including but not limited to reports on an ADE, and shall provide

         Section 16.10. FURTHER ACTIONS. Upon the terms and subject to the
conditions hereof, each of the Parties hereto shall use its commercially
reasonable efforts to (i) take, or cause to be taken, all appropriate action and
do, or cause to be done, all things necessary, proper or advisable under
Applicable Law or otherwise to consummate and make effective the transactions
contemplated by this Agreement, (ii) obtain from Competent Authorities any
consents, licenses, permits, waivers, approvals, authorizations or orders
required to be obtained or made by the Parties in connection with the
authorization, execution and delivery of this Agreement and the consummation of
the transactions contemplated by this Agreement and (iii) make all necessary
filings, and thereafter make any other required submissions, with respect to
this transaction under





                                       41
   47

(A) the Securities Exchange Act of 1934, as amended and the Securities Act of
1933, as amended, and the rules and regulations thereunder 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 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






                                       42
   48

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
         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

         against amounts otherwise due by MediGene to Atrix hereunder; and

                  (c) if such Recall is due to the negligence or the breach by

         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

         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:




                                       44
   50

                  (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
         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

   51

         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 right to practice within the Atrigel(R) Patent
         Rights or use any of the Atrigel(R) 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






                                       46
   52

                           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 inventory of Product and Demonstration
                           Samples to Atrix or (2) destroy all remaining

                           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

         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

neither this Agreement nor any rights or obligations hereunder may be assigned

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

         Section 20.09. INDEPENDENT CONTRACTORS. It is expressly agreed that
Atrix and MediGene shall be independent contractors and that the relationship
between the two Parties shall not constitute a partnership or agency of any
kind. Neither Atrix nor MediGene shall have the authority to make any
statements, representations or commitments of any kind, or to take any action,
which shall be binding on the other Party, without the prior written consent of
the other Party.

         Section 20.10. RULES OF CONSTRUCTION. The Parties hereto agree that
they have been represented by counsel during the negotiation and execution of
this Agreement and, therefore, waive the application of any law, regulation,
holding or rule of construction providing that ambiguities in an agreement or
other document will be construed against the Party drafting such agreement or
document. Whenever the context hereof shall so require, the singular shall
include the plural, the male gender shall include the female gender and neuter,
and vice versa.

         Section 20.11. PUBLICITY. MediGene and Atrix shall consult with each
other before issuing any press release with respect to this Agreement or the
transactions contemplated hereby and neither shall issue any such press release
or make any such public statement without the prior consent of the other, which
consent shall not be unreasonably withheld; provided, however, (a) that a Party
may, without the prior consent of the other Party, issue such press release or
make such public statement as may upon the advice of counsel be required by law
or the rules and regulations of the Nasdaq or any other stock exchange, or (b)
if it has used reasonable efforts to consult with the other Party prior thereto,
(such consent shall be deemed to have been given if the recipient of the press
release or public statement fails to respond to the other Party within
forty-eight (48) hours after the recipient's receipt of such press release or
public statement). No such consent of the other Party shall be required to
release information which has previously been made public.

         Section 20.12. ENTIRE AGREEMENT; AMENDMENT. This Agreement (including
the Exhibits attached hereto) sets forth all of the covenants, promises,
agreements, warranties, representations, conditions and understandings between
the parties hereto with respect to the subject matter hereof and supersedes and
terminates all prior agreements and understandings between the Parties. There
are no covenants, promises, agreements, warranties, representations conditions
or understandings, either oral or written, between the parties other than as set
forth herein. No subsequent alteration, amendment, change or addition to this
Agreement shall be binding upon the Parties hereto unless reduced to writing and
signed by the respective authorized officers of the Parties.

         Section 20.13. HEADINGS. The captions contained in this Agreement are
not a part of this Agreement, but are merely guides or labels to assist in
locating and reading the several articles hereof.

         Section 20.14. COUNTERPARTS. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to be
executed in duplicate by their duly authorized officers as of the Effective
Date.
