         7.4 Specifications. The current specifications for Bulk Licensed
Compound are attached to this Agreement as Exhibit II (as such specifications
may be modified pursuant to this Section, the "Specifications"). Biosearch shall
***** during the term of this Agreement make changes to the Specifications for
Bulk Licensed Compound without good reason and the prior approval of GENE.
Biosearch may modify Specifications if regulatory authorities within the
Territory recommend or require changes thereto, or if GENE submits a proposal
for changing such Specifications. Notwithstanding the previous sentence, both
Parties shall use their ***** to implement changes in the Specifications which
are required by the regulatory authorities within the Territory unless both
Parties agree to the contrary in writing. At the request of GENE, Biosearch
shall arrange for GENE's designated representatives to inspect and visit from
time to time the facilities at which Bulk Licensed Compound is manufactured,
stored or tested for the purpose of determining that the manufacture of Bulk
Licensed Compound complies with the requirements of this Agreement. Such
inspections shall occur during regular business hours upon reasonable notice.

         7.5 Forecasting. ***** days before the end of each ***** following the
Effective Date, GENE will provide Biosearch with a firm order for Bulk Licensed
Compound for the subsequent ***** together with a rolling forecast covering the
***** following the one for which the firm order was issued. The order for the

the Effective Date, and shall be subject to Biosearch's acceptance, not to be
unreasonably withheld. In no event shall Biosearch be required to deliver more
Bulk Licensed Compound in any given ***** than the firm order that was submitted
by GENE for such *****in the last applicable forecast. Biosearch shall use
commercially reasonable efforts to supply any additional quantities requested by
GENE in excess of the amounts previously forecasted by GENE, it being recognized
that substantial increases in production levels may require significant advance
notice.

         7.6 Shipment of Bulk Licensed Compound. Biosearch shall deliver the
Bulk Licensed Compound it manufactures for GENE pursuant to this Article 7 to
location(s) designated by GENE by such method and carrier as GENE shall request.
Unless otherwise agreed by the Parties, all shipments of Bulk Licensed Compound
by Biosearch shall be ex-works Biosearch. Biosearch shall use best efforts to
deliver Bulk Licensed Compound on the dates specified by GENE. Biosearch will
bear all transportation expenses for the delivery of material to GENE, and shall
bear all risk of loss of any material following shipment from the place of
manufacture until delivered to GENE.

         7.7 Invoices. Biosearch will invoice GENE for each shipment of material
supplied to GENE under this Article 7. GENE shall pay the relevant invoices
within ninety (90) days after its receipt thereof.

         7.8 Acceptance. Prior to shipment of Bulk Licensed Compound, Biosearch
will ship representative samples of each batch to be shipped to GENE. Upon
receipt of such sample and upon receipt of a shipment of Bulk Licensed Compound,
GENE may determine whether the sample and such shipment, respectively, meet the
Specifications. GENE shall notify Biosearch in writing promptly if such sample
or shipment of Bulk Licensed Compound, as applicable, manufactured by Biosearch
fails to meet the Specifications, therefor. If Biosearch has not received such
written notice within thirty (30) days after such material has been received by
GENE, then such shall be deemed to have met the Specifications. Upon receipt of
any such written notice of non-conformance, Biosearch shall either acknowledge
that the subject Bulk Licensed Compound does not meet the Specifications, or
resample the sample, lot or batch in question and have said samples tested by an
independent laboratory of its choice, acceptable to GENE. If such independent
laboratory determines that such samples fail to meet the Specifications or
Biosearch acknowledges that Bulk Licensed Compound is non-conforming, then
Biosearch shall at GENE's option either replace the non-conforming Bulk Licensed
Compound at no additional cost as soon as reasonably possible or refund any
payments made by GENE for such non-conforming materials.

         7.9 Transfer Price for Clinical Supply and Validation Process. Prior to
receipt of Regulatory Approval of the Licensed Product in the Territory, and
subject to Biosearch's obligation under Section 2.3(c) herein, GENE will
purchase clinical supplies of Bulk Licensed Compound at a price (the "Transfer
Price") equal to ***** of Bulk Licensed Compound.

         7.10 Manufacturing Reports. The reports that Biosearch shall provide
pursuant to Section 2.4(a) shall include details of Biosearch's efforts to scale
up the manufacturing process for Bulk Licensed Compound at alternate sites
pursuant to Section 2.3.

         7.11 Retention of Back-up Supply of Bulk Licensed Compound. To help
protect against interruptions in supply of Bulk Licensed Compounds pursuant to
this Article 7, Biosearch shall retain under appropriate conditions a supply of
Bulk Licensed Compound at all times after the parties commence production of
Licensed Products for commercial launch in an amount determined pursuant to this
Section. GENE shall notify Biosearch at least ninety (90) days prior to
commencement of commercial scale manufacture of Licensed Product of the amount
of Bulk Licensed Compound that constitutes a sufficient supply for the purpose
of this Section 7.11 (the "Retained Amount"). GENE may re-establish the Retained
Amount from time to time as necessary or desirable in view of its good faith
estimate of its requirements for Bulk Licensed Compounds during the remainder of
the term of this Agreement.

         7.12 Discussions Regarding Long Term Supply Capacity. The parties
acknowledge that GENE will gain knowledge regarding the potential market for
Licensed Products in the Field and in the Territory as the development of
Licensed Products progresses. Accordingly, it is possible that GENE's full
commercial requirements for Bulk Licensed Compounds either upon commercial
launch of Licensed Products or thereafter may exceed the capacity at Biosearch's
manufacturing facility therefor. If at any time GENE's good faith estimate of
the market for Licensed Products indicates that Biosearch's current
manufacturing facility may not have sufficient capacity for manufacturing GENE's
requirements for Bulk Licensed Compound over the term of this Agreement, then
GENE and Biosearch shall discuss in good faith acceptable mechanisms for any
such actual or potential inability of Biosearch to supply GENE' requirements,
which may include without limitation for the establishment of a second
manufacturing site by Biosearch. If the parties do not agree on such mechanisms
for assuring sufficient supply of Bulk Licensed Compound and appropriate
amendments to this Agreement implementing such mechanisms, then GENE may elect
to establish a second manufacturing site.

considered determinable if either Party can determine such price to the
reasonable satisfaction of the other Party.

         Notwithstanding the foregoing, the Parties agree to the desirability of
maintaining a competitive price and competitive supply arrangements for Licensed
Products in the face of increased competition. In the event that the adjustments
to the total payments described in the table above are not able or are
inadequate to meet GENE's needs to modify GENE's costs for Licensed Products as
reasonably determined by GENE, the Parties hereby agree to negotiate in good
faith to establish other mechanisms as may be deemed necessary to maintain
competitiveness in the marketplace.

                  (b)   The Royalty payable by GENE hereunder shall be subject

                  (b) Biosearch has an obligation to produce ***** of Bulk
Licensed Compound for validation of the Biosearch manufacturing process and
facility. GENE has agreed to accept a maximum of ***** of this material. GENE
will accept ***** of this material as a credit toward its entitlement to free
goods allowance described in Section 8.5(a). GENE will pay for ***** of the
material at a price of *****. Payment will be due one hundred twenty (120) days
post launch a Licensed Product in the U.S. This material will be stored at
Biosearch until Gene needs to "run" the finished product manufacturing campaign.
GENE shall notify Biosearch when this material must be manufactured and the
material must meet the Specifications. GENE shall use such material to validate
its formulation and finishing process pursuant to 2.2(a). In the event that all
of the material is not required for the validation of GENE's formulation and
finishing process and the remaining shelf life of the unused material does not
allow for its formulation and finishing, then GENE shall not be obligated to pay
for such unused material but shall return it to Biosearch. The material will be
manufactured at the time indicated by GENE. In the event that the Licensed
Product becomes non-exclusive in the territory, prior to the time at which
Biosearch has fulfilled its obligations under this clause, the price to be paid
for this material will be reduced to the TBP if the TBP is less than *****.

         8.6 Supply Price Payments, Royalty Payments and Sublicense Revenue
Payments.

                  (a) Biosearch shall deliver Bulk Licensed Product and shall
invoice GENE at the Supply Price. GENE shall notify Biosearch of its receipt
thereof and pay such invoices within ninety (90) days after receipt of such Bulk
Licensed Compound.

                  (b) GENE will deliver to Biosearch a report showing in detail
its calculation of the Net Sales and quantities of any Licensed Products sold
during a given ***** within thirty (30) days following the end of such ***** and
sixty (60) days following the end of each calendar year for which Royalty or
other royalty payments are due from GENE. GENE shall pay the Royalty or other
royalty due on Net Sales or quantity of Licensed Product sold during the *****
covered by a given report under this Section 8.6(b) within thirty (30) days
after GENE provides such report to Biosearch.

                  (c) GENE will deliver a report showing in detail its
calculation of the Net Sales and quantities of any Licensed Products sold by
GENE's sublicensees during a given ***** to Biosearch within thirty (30) days
following the end of each ***** and sixty (60) days following the end of each
calendar year for which payments are due from GENE to Biosearch thereon. GENE
shall pay the amounts due to Biosearch on Net Sales and quantities of Licensed
Product sold by GENE's sublicensees pursuant to Section 8.2 and 8.3 for a given
***** covered by such reports within thirty (30) days after GENE provides such
report to Biosearch.

         8.7 Exchange Rate; Manner and Place of Payment. All amounts paid to
Biosearch hereunder shall be paid in United States currency. Net Sales shall be
accounted for on a ***** basis in U.S. Dollars for each month

on the last banking day of such ***** . All payments due to Biosearch under this
Agreement shall be made by wire transfer at a bank and to an account designated
by Biosearch, unless otherwise specified by Biosearch.

         8.8  Late Payments. In the event that any payment due hereunder is not
made when due, interest shall accrue on the late payment from the due date of
such payment at the ***** as then quoted in the Wall Street Journal. The payment
of such interest shall not limit any Party from exercising any other rights it
may have as a consequence of the lateness of the payment.

         8.9  Record Keeping. During the term of this Agreement, GENE shall keep
full and accurate books and records setting forth, for the Licensed Product on
which payments are due, including gross sales, all deductions allowed in
arriving at Net Sales and any other information necessary and in sufficient
detail to allow the calculation of payments to be paid by GENE. During the term
of this Agreement and for a period of ***** thereafter, GENE shall permit
Biosearch, at Biosearch's expense, by independent certified public accountants
employed by Biosearch and reasonably acceptable to GENE, to examine relevant
books and records at any reasonable time, not more often than once each calendar
year, within ***** of any such payment. If it is determined that there was an
underpayment due Biosearch of ***** or more, without prejudice to any other
rights Biosearch may have, GENE shall promptly pay to Biosearch the balance of
the amounts due and shall also reimburse Biosearch for the cost of such
verification examination.

         8.10 Tax and Withholdings. Any withholding taxes levied by tax
authorities in the Territory on the payments hereunder, to the extent due by
Biosearch and not transferable upon GENE, shall be borne by Biosearch and
deducted by GENE from the sums otherwise payable by it hereunder for payment to
the proper tax authorities on behalf of Biosearch. In such event, GENE shall
deliver to Biosearch evidence of the payment of such taxes. GENE agrees to
cooperate with Biosearch in the event Biosearch claims exemption from such
withholding or seeks deductions under any double taxation or other similar
treaty or agreement from time to time in force.

                                    ARTICLE 9

                                 CONFIDENTIALITY

         9.1  Confidentiality; Exceptions. Except to the extent expressly
authorized by this Agreement or otherwise agreed in writing, the Parties agree
that, the receiving Party shall keep confidential and shall not publish or
otherwise disclose or use for any purpose other than as provided for in this
Agreement any Information and other information and materials furnished to it by
the other Party pursuant to this Agreement, or any provisions of this Agreement
that are the subject of an effective order of the Securities Exchange Commission
granting confidential treatment pursuant to the Securities Act of 1934, as
amended (collectively, "Confidential Information"), except to the extent that it
can be established by the receiving Party that such Confidential Information:

              (a) was already known to the receiving Party, other than under an
obligation of confidentiality, at the time of disclosure by the other Party;

              (b) was generally available to the public or otherwise part of the
public domain at the time of its disclosure to the receiving Party;

              (c) became generally available to the public or otherwise part of
the public domain after its disclosure and other than through any act or
omission of the receiving Party in breach of this Agreement; or

              (d) was disclosed to the receiving Party, other than under an
obligation of confidentiality, by a Third Party who had no obligation to the
disclosing Party not to disclose such information to others.
- ----------
*Confidential Treatment has been requested for the marked portions.

Page 17



        9.2 Authorized Disclosure. Each Party may disclose Confidential
Information hereunder to the extent such disclosure is reasonably necessary in
filing or prosecuting patent applications, prosecuting or defending litigation,
complying with applicable governmental regulations or conducting preclinical or
clinical trials, provided that if a Party is required by law or regulation to
make any such disclosure of the other Party's Confidential Information it will,
except where impracticable for necessary disclosures (for example in the event
of medical emergency), give reasonable advance notice to the other Party of such
disclosure requirement and, except to the extent inappropriate in the case of
patent applications, will use its reasonable efforts to secure confidential
treatment of such Confidential Information required to be disclosed. In
addition, each Party shall be entitled to disclose, under a binder of
confidentiality containing provisions as protective as those of this Article 9,
Confidential Information to any Third Party for the purpose of carrying out
activities authorized under this Agreement, including disclosures to authorized
sublicensees, and subject to Sections 2.5 and 2.6 disclosures by Biosearch for
purposes of the development and commercialization of products other than
Licensed Products anywhere in the world outside of the Field, and of Licensed
Products either outside of the Field and within the Territory, or within the
Field and outside of the Territory. Nothing in this Article 9 shall restrict any
Party from using for any purpose any Information developed by it during the
course of the collaboration hereunder. Biosearch acknowledges that if GENE files
a required Securities Exchange Commission filing or registration statement
covering the sale of its securities in the United States, it will be required to
file a copy of this Agreement with its public disclosure statement. GENE agrees
to seek confidential treatment of at least the economic terms of this Agreement
with respect to any such filing.

        9.3  Publications. Except as required by law, each Party agrees that it
shall not publish or present Information relating to the Licensed Compound or to
products containing the Licensed Compound without providing to the other Party
the opportunity for prior review of such publication or presentation. The Party
desiring to publish or present such Information (the "Proposing Party") shall
provide to the other Party the opportunity to review such proposed publication
or presentation (including information to be presented verbally) as early as
reasonably practical, but not later than twenty (20) days prior to the
anticipated date of submission or disclosure to a Third Party. The Party
reviewing such publication or presentation shall respond to the Proposing Party
with comments thereon within ten (10) days of receiving such materials from the
Proposing Party. The Proposing Party agrees, upon written request from the other
Party, not to submit such abstract or manuscript for publication or to make such
presentation until the other Party consents, which agreement shall not be
unreasonably withheld.

        This Article 9 shall survive termination or expiration of this Agreement
for a period of five (5) years thereafter.

                                   ARTICLE 10

              OWNERSHIP OF INTELLECTUAL PROPERTY AND PATENT RIGHTS

        10.1 Ownership. Each Party shall solely own, and it alone shall have
the right to apply for, Patents within and outside of the Territory for any
inventions made solely by that Party's employees or consultants in the course of
performing work under this Agreement. Inventions made jointly by personnel of
Biosearch and GENE shall be jointly owned by the Parties ("Joint Patents"),
subject to the licenses granted to GENE pursuant to Article 5.

        10.2 Disclosure of Patentable Inventions. Each Party shall provide to
the other any patent application disclosing an invention or jointly conceived
invention relating to Licensed Products within the Field arising during the term
of this Agreement reasonably in advance of the intended date for submission of
any patent application to a governmental patent authority.

        10.3 Patent Filings.

Page 18



              (a) Biosearch Responsibilities. Biosearch shall prepare, file,
prosecute and maintain Patents to cover inventions relating to the discovery,
evaluation, manufacture, use or sale of Licensed Products that are made solely
by Biosearch personnel (all of which shall be included in the Biosearch Patents)
or that are made jointly by personnel of Biosearch and GENE in the course of the
collaboration ("Joint Patents", all of which shall be included in both the
Biosearch Patents and GENE Patents). Biosearch shall keep GENE informed of the
status of each such Biosearch Patent and Joint Patent and shall give reasonable
consideration to any suggestions or recommendations of GENE concerning the
preparation, filing, prosecution and maintenance thereof. The Parties shall
cooperate reasonably in the prosecution of all Biosearch Patents and Joint
Patents under this Section 10.3(a) and shall share all material Information
relating thereto promptly after receipt of such Information. If, during the term
of this Agreement, Biosearch intends to allow any issued Biosearch Patent or
Joint Patent to which GENE has a license under this Agreement to expire for
failure to make maintenance fee payments, Biosearch shall notify GENE of such
intention at least sixty (60) days prior to the date upon which such issued
Biosearch Patent or Joint Patent shall expire, and GENE shall thereupon have the
right, but not the obligation, to assume responsibility for the maintenance
thereof

              (b) GENE Responsibilities. GENE shall file, prosecute and maintain
Patents to cover inventions relating to the discovery, evaluation, manufacture,
use or sale of Licensed Products that are made solely by GENE personnel (all of
which shall be included in GENE Patents). GENE shall keep Biosearch informed of
the status of each GENE Patent and shall give reasonable consideration to any
suggestions or recommendations of Biosearch concerning the preparation, filing,
prosecution and maintenance thereof. The Parties shall cooperate reasonably in
the prosecution of all GENE Patents under this Section 10.3(b) and shall share
all material Information relating thereto promptly after receipt of such
Information. If, during the term of this Agreement, GENE intends to allow any
issued GENE Patent to which Biosearch has a license under this Agreement to
expire for failure to make maintenance fee payments, GENE shall notify Biosearch
of such intention at least sixty (60) days prior to the date upon which such
GENE Patent shall expire, and Biosearch shall thereupon have the right, but not
the obligation, to assume responsibility for the maintenance thereof.

         10.4 Third Party Patent Rights. No Party makes any warranty with
respect to the validity, perfection or dominance of any Patent or other
proprietary right or with respect to the absence of rights in Third Parties
which may be infringed by the manufacture or sale of the Licensed Product. Each
Party agrees to bring to the attention of the other Party any patent or patent
application it discovers, or has discovered, and which relates to the subject
matter of this Agreement.

         10.5 Enforcement Rights.

              (a) Infringement by Third Parties. If any Biosearch Patent or GENE
Patent is infringed by a Third Party in the Territory in connection with the
manufacture, import, use, sale or offer for sale of a product competitive with a
Licensed Product ("Competitive Product Infringement"), the Party to this
Agreement first having knowledge of such infringement shall promptly notify the
other in writing. The notice shall set forth the facts of that infringement in
reasonable detail. GENE shall have the primary right, but not the obligation, to
institute, prosecute or control any action or proceeding with respect to such
infringement of a Biosearch Patent or Joint Patent within the Field and within
the Territory, or of a GENE Patent anywhere in the world both within and outside
of the Field, by counsel of its own choice. Biosearch shall have the right to
participate in such action and to be represented by counsel of its own choice.
Biosearch shall have the primary right, but not the obligation, to institute,
prosecute, and control any action or proceeding with respect to such
infringement of Biosearch Patents or Joint Patent occurring within the Territory
that is outside of the Field, or occurring anywhere else in the world both
within and outside of the Field, by counsel of its own choice. Solely within the
Territory with respect to Biosearch Patents other than Joint Patents and
anywhere in the World with respect to Joint Patents, GENE shall have the right
to participate in such action brought by Biosearch pursuant to the foregoing
sentence and to be

Page 19



represented by counsel of its own choice therein. If the Party primarily
responsible for bringing suit under this Section 10.5(a) (the "Responsible
Party") fails to bring an action or proceeding within a period of ninety (90)
days after having knowledge of that infringement, then, solely with respect to
infringement occurring inside the Field and inside the Territory with respect to
infringement of patents, the other Party shall have the right to bring and
control any such action by counsel of its own choice, and the Responsible Party
shall have the right to participate in such action and be represented by counsel
of its own choice. If a Responsible Party brings any such action or proceeding
hereunder, the other Party agrees to be joined as a party plaintiff and to give
the Responsible Party reasonable assistance and authority to control, file and
prosecute the suit as necessary. The costs and expenses of the Party bringing
suit under this Section (including the internal costs and expenses specifically
attributable to said suit) shall be reimbursed first out of any damages or other
monetary awards recovered in favor of the Parties. Any remaining damages shall
be split in accordance with each Party's interest therein. No settlement or
consent judgment or other voluntary final disposition of a suit under this
Section 10.5(a) may be entered into without the joint consent of Biosearch and
GENE.

              (b) Defense and SettIement of Third Party Claims against Licensed
Products. If a Third Party asserts that a patent or other right owned by it is
infringed by the manufacture, import, use, sale or offer for sale of any
Licensed Product, the Party first obtaining knowledge of such a claim shall
immediately provide the other Party notice of such claim and the related facts
in reasonable detail. Defense of any such claim in the Field and in the
Territory shall be controlled by GENE; provided that Biosearch shall have the
right to participate in such defense and to be represented in any such action by
counsel of its selection at its sole discretion. GENE shall also have the right
to control settlement of such claim with respect to a Licensed Product in the
Field and in the Territory; provided, however, that no settlement shall be
entered into without the written consent of Biosearch, which consent shall not
be withheld unreasonably.

              (c) Allocation of Expenses Incurred Pursuant to Section 10.5(b).
The expenses of patent defense, settlement and judgments pursuant to Section
10.5(b) with respect to the Licensed Products shall be borne solely by GENE,
except as provided in Section 10.5(d).

              (d) Settlement of Third Party Claims for Infringement; Payment of
Third Party Royalties. If a Third Party asserts that a patent or other right
owned by it is infringed by the manufacture, use, sale, offer for sale or import
of any Licensed Product, and as a result of settlement procedures or litigation
under this Section 10.5, GENE is required to pay the Third Party a royalty or
make any payment of any kind for the right to sell a Licensed Product in a
particular country, such expense shall be borne by Biosearch as set forth in
Section 8.3.

              (e) Agreement of Primarily Responsible Party. Notwithstanding the
provisions of Section 10.5(a), neither Party shall file and prosecute an action
for infringement of a Patent for which the other Party has the primary
responsibility to file and prosecute such action, and pursuant to which that
other Party having primary responsibility has commenced and is prosecuting at
least one such action for infringement of said Patent, without the agreement of
that other Party, which agreement shall not be unreasonably withheld.

         10.6 Patent Marking. GENE shall mark Licensed Products with appropriate
patent numbers or indicia as necessary to maintain the enforceability of
Biosearch Patents, Joint Patents and GENE Patents.

         10.7 Trademarks and Trade Names.

              (a) Product Trademarks and Trade Names. The Parties agree to the
principle and desirability of identifying and registering with the appropriate
trademark authorities global trademark(s) ("Global Trademarks") and global trade
name(s) ("Global Trade Names") for Licensed Products and Bulk Licensed Compound.
Such Global Trademarks and Global Trade Names for Licensed Products and Licensed
Compound shall at all times be the exclusive property of Biosearch. Subject to
the following paragraph, Biosearch and GENE shall jointly select, prosecute
applications for, register, maintain and enforce the Global Trademarks and
Global Trade Names for Licensed Products in the Territory, at Biosearch's
expense. All uses of trademarks or trade

Page 20



names to identify a Licensed Product shall comply with all applicable laws and
regulations, including without limitation those laws and regulations
particularly applying to the proper use and designation of trademarks and trade
names.

       Should it be determined by GENE that a Global Trademark or Global Trade
Name is unavailable or becomes the subject of an opposition in the Territory, or
should the Parties be unable to reach agreement on such Global Trademark or
Global Trade Name, GENE shall have the right to select, prosecute applications
for, register, maintain and enforce trademarks and trade names for Licensed
Products in the Territory ("Territory Trademarks" and "Territory Trade Names",
respectively) at its own expense. Such Territory Trademarks and Territory Trade
Names shall at all times be the exclusive property of GENE.

       Notwithstanding the foregoing, without limitation all branding, logos,
indicia and trade dress, shall be developed by GENE in its sole discretion for
use in the Territory, whether for use with a Territory Trademark or Territory
Trade Name. Such branding, logos, indicia and trade dress, without limitation,
shall be the exclusive property of GENE and may be licensed to Biosearch, at
Biosearch's request, for the exclusive use with Licensed Products outside the
Territory on a royalty-free basis.

              (b) Infringement. Each Party shall notify the other Party promptly
upon learning of any actual, alleged or threatened infringement of the trademark
for Licensed Product in the Field and in the Territory or of any unfair trade
practices, trade dress imitation, passing off of counterfeit goods or like
offenses. The parties shall confer regarding the appropriate steps necessary or
useful to protect, enforce and maintain such trademark. GENE shall make the
final decision of whether and how to defend the trademark.

              (c) License. Biosearch hereby grants to GENE a fully paid license
to use all Global Trademarks and Global Trade Names and any other Trademarks and
Trade Names owned or Controlled by Biosearch under which Biosearch sells and
markets products containing the Bulk Licensed Compound solely in connection with
GENE's Development and Commercialization of Licensed Products in the Field and
in the Territory pursuant to this Agreement. GENE may sublicense any rights
under the Biosearch Global Trademarks and/or Global Trade Names persuant to
Section 5.5 of this Agreement. GENE hereby grants to Biosearch a fully paid
license to use any Territory Trademarks and Territory Trade Names solely in
connection with Biosearch's Development and Commercialization of products
containing Bulk Licensed Compound in the Field outside of the Territory.
Biosearch may not sublicense any right under the Territory Trademark or
Territory Trade Name with out the prior written consent of GENE.

       10.8 Trade Secrets. The parties each acknowledge that Biosearch maintains
certain technology useful for the manufacture of the Bulk Licensed Compound as a
trade secret and that accordingly Biosearch has chosen not to seek patent
protection on such technology. Biosearch hereby agrees that it shall use all
commercially reasonable efforts to maintain such technology as a trade secret
(unless and until Biosearch files a patent application claiming such
technology), including without limitation (i) disclosing such technology to
third parties only under an obligation of confidentiality and non-use with
respect thereto comparable in scope to the confidentiality and non-use
obligations set forth in Article 9 with respect to Confidential Information,
(ii) not disclosing any trade secrets in any public presentation or publication
and (iii) employing other mechanisms typically used in the pharmaceutical
industry to protect trade secrets of similar nature.

                                   ARTICLE 11

                              TERM AND TERMINATION

       11.1 Term. Except as otherwise provided herein, the term of this
Agreement shall commence on the Effective Date and, unless earlier terminated as
provided in this Agreement, shall expire ten (10) years after first commercial
sale of a Licensed Product by GENE in the Field and in the Territory. In the
event that at any time

Page 21



during the term of this Agreement, Biosearch is merged into or acquired by a
Third Party or sells to a Third Party all or substantially all of the assets to
which this Agreement relates, GENE shall have an option, exercisable at any time
prior to the expiration of the term, to extend the agreement for an additional
five (5) years up to a total of fifteen (15) years under the same terms and
conditions stated herein, and at no additional economic terms. Except as
provided under Section 8.5, the terms and conditions of this Agreement will
automatically renew for subsequent periods of two (2) years at the end of the
initial ten year term, subject to either party's right not to renew, to be
communicated in writing to the other party with at least one (1) year advance
notice; provided that Biosearch's right to not renew the term of this Agreement
shall, in any event, be subject to Biosearch's obligation to provide a minimum
of two (2) years notice to GENE if Biosearch should choose not to supply Bulk
Licensed Compound, pursuant to Section 7.2(ii). In this event, Biosearch will
supply GENE the manufacturing know-how and the most productive seed strain to
enable GENE to produce or have produced the Bulk Licensed Compound. Upon
termination of this Agreement pursuant to this Section 11.1, GENE's license
under Article 5 shall continue in full force and effect and GENE may thereafter
continue to sell Licensed Products in the Field and in the Territory on a
royalty free basis.

       11.2 Termination for Cause. Either Party may terminate this Agreement
upon sixty (60) days written notice 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 the sixty (60) day period following written notice of
termination by the other Party.

       11.3 Other Termination.

              (a) By GENE. GENE shall have the right to terminate this Agreement
upon ninety (90) days prior written notice to Biosearch if the prospects for
achieving Regulatory Approval for a Licensed Product or commercially feasible
Development or Commercialization of a Licensed Product appear in GENE's
reasonable judgment not to justify further support of the Licensed Product.

              (b) By Biosearch. If the NDA for the US has not been filed by GENE
by *****, unless due to force majeure conditions or reasons beyond GENE's
reasonable control (with the agreement that this date and clause shall at all
times be kept confidential), Biosearch shall have the right to terminate this
Agreement, and will have the right to acquire or have returned, in any event at
no cost, all rights, authorizations, approvals, materials and information
concerning Ramoplanin developed by or licensed to GENE.

       11.4 Effect of Termination.

              (a) Upon termination of this Agreement by Biosearch for GENE's
material breach pursuant to Sections 11.2, or by GENE pursuant to Section 11.3,
all rights and licenses granted to GENE with respect to the Licensed Product
under Article 5 shall terminate. Furthermore, GENE shall pay all sums accrued
hereunder which are then due (except as expressly otherwise provided in this
Agreement), shall promptly assign to Biosearch all right, title and interest in
and to any regulatory filings in the Territory pertaining to Licensed Products
and shall deliver to Biosearch any GENE Information necessary to obtain the
Regulatory Approval of Licensed Products in the Territory which has not been
obtained as of the date of termination. If this Agreement is terminated by
Biosearch pursuant to Section 11.2 or 11.3(b), or by GENE pursuant to Section
11.3(a), GENE shall return to Biosearch, or at Biosearch's request destroy, all
Biosearch Information and any other Confidential Information relating to the
Licensed Compound or Licensed Products, and any Bulk Licensed Compound supplied
by Biosearch for clinical development or commercial distribution. Additionally,
if Biosearch terminates this Agreement pursuant to Section 11.2 or GENE
terminates this Agreement pursuant to Section 11.3, the license granted in
Section 5.2 shall automatically become, without any further action by GENE, an
exclusive, worldwide, royalty-free license under the GENE Patents to make, have
made, use, import, offer, sell, offer for sale and have sold the Licensed
Compound and pharmaceutical products containing the Licensed Compound (including
without limitation Licensed Products) for any and all uses.

Page 22



              (b) Upon termination of this Agreement by GENE for Biosearch's
material breach pursuant to Section 11.2, all licenses granted to GENE shall
survive. If Biosearch is supplying Licensed Bulk Compound at the time of any
termination by GENE of this Agreement for Biosearch's material breach, Biosearch
shall continue to provide for supply of Bulk Licensed Compound to the extent
provided prior to notice of such termination until such time as GENE is able to
secure an equivalent alternative commercial supply source for the Territory, as
requested by GENE; and Biosearch shall take the actions described in and be
obligated under Section 7.2(iii); provided, however, that GENE shall pay to
Biosearch its Cost of Goods Sold for such Bulk Licensed Compound. Any additional
payments for such supply shall be negotiated between the Parties at such time of
termination.

        11.5  Accrued Rights, Surviving Obligations. Termination of this
Agreement shall not affect any accrued rights and remedies of either Party.
Additionally, the terms of Articles 7 (solely to the extent required to effect
the intent of Section 11.4, if applicable), 8 (solely to the extent required to
effect the intent of Section 11.4, if applicable), 9, 12, 13 and 14, as well as
Sections 10.2 through 10.8, 11.4, 11.5, of this Agreement shall survive any
termination or expiration of this Agreement.

                                   ARTICLE 12

                         REPRESENTATIONS AND WARRANTIES

        12.1  Mutual Representations and Warranties. Each Party hereby
represents and warrants:

              (a) Corporate Power. Such Party is duly organized and validly

conflict with any agreement, instrument or understanding, oral or written, to
which it is a Party or by which it may be bound, nor violate any law or
regulation of any court, governmental body or administrative or other agency
having jurisdiction over it. Such Party has not, and during the term of the
Agreement will not, grant any right to any Third Party with respect to its
Patents or Know-how that would conflict with the rights granted to the other
Party hereunder.

        12.2  Representations by Biosearch Regarding Manufacture of Bulk
Licensed Compounds. Biosearch hereby warrants that the Bulk Licensed Compound
supplied hereunder will:

              (a) comply with the Specifications then in effect for Bulk
Licensed Compound;

of competent jurisdiction in the country where such patent has issued.

       14.3 Force Majeure. Save as provided in Section 4.2 above, neither Party

                                CONVERTIBLE NOTE

        THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
        AMENDED (THE "ACT") OR UNDER THE SECURITIES LAWS OF ANY STATE, AND MAY
        NOT BE SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION
        OR AN EXEMPTION THEREFROM UNDER THE ACT AND ANY SUCH APPLICABLE STATE
        LAWS.

        GENOME THERAPEUTICS CORP.

        CONVERTIBLE NOTE DUE [INSERT DATE 60 MONTHS AFTER DATE OF ISSUE]

$[Amount]                                                       [Date of Issue]

FOR VALUE RECEIVED, the undersigned Genome Therapeutics Corp., a Massachusetts
corporation (the "Company"), hereby promises to pay to Biosearch Italia, S.p.A.,
or registered assigns, at the address specified in Section 14.9 of the License
and Supply Agreement (as defined below), or at such other place as the Holder of
this Note shall from time to time have designated to the Company in writing, on
[insert date 60 months after Date of Issue] (the "Stated Maturity Date"),
[AMOUNT IN WORDS ($[Amount in numbers]) (the "Principal Amount"), with interest
as provided in Section 1 hereof.

1. INTEREST. This Note shall accrue daily interest from the date hereof,
computed on the basis of a year of 365 or 366 (as applicable) days and actual
days elapsed, on the principal amount from time to time unpaid at a rate per
annum equal to five percent (5%) (the "Applicable Rate"), said interest being
payable in arrears on the last business day of the calendar month in which this
Note was issued in each year (each such day, and the day that is the Stated
Maturity Date, being a "Payment Date"), commencing on [insert date that is the
last business day of the month in which the Note is issued, one year following
the date of issue], and at the stated or any accelerated maturity hereof. All
interest shall be payable in cash in the lawful money of the United States.

2.   PAYMENT PROVISIONS. The Company covenants that so long as this Note is
outstanding:

        2.1. Payment at Maturity of Note. On the Stated Maturity Date, and on
any accelerated maturity of the Notes, the Company will pay the entire principal
amount of this Note then outstanding, together with all accrued and unpaid
interest thereon.

        2.2. Prepayments. Except as provided in Section 4.2 hereof, the Company
may not prepay all or any part of the principal amount of the Notes.

3.      CONVERSION OF NOTE.

        3.1. Conversion by Holder. Subject to Section 3.4, the Holder of this
Note may at any time convert the principal amount of this Note then outstanding
into a number of shares of Common Stock equal to (x) the aggregate amount of
principal of this Note divided by (y) the Conversion Price (as hereinafter
defined). As used herein, the "Conversion Price" shall initially be $15.00,
shall be adjusted and readjusted from time to time as provided in this Section 3
and, as so adjusted or readjusted, shall remain in effect until a further
adjustment or readjustment thereof is required by Section 3 of this Note. Such
conversion shall be effected by surrender of this Note to the Company at its
office specified in Section 14.9 of the License and Supply Agreement,
accompanied by a Conversion Notice in substantially the form attached to this
Note (or a reasonable facsimile thereof) executed by such Holder, and such
Holder shall thereupon be entitled to receive the number of shares of Common
Stock specified in the first sentence of this Section 3.1 or the shares or other
interests specified in Section 3.4 below. The conversion of this Note shall be
deemed to have been effected immediately prior to the close of business on the
business day on which this Note shall have been surrendered to the Company as
provided in the immediately preceding sentence, and at such time the Holder
shall be deemed to have become the holder of record of such shares of Common
Stock. As soon as practicable after conversion of the Note, and in any event
within five business days thereafter, the Company at its expense will cause to
be issued in the name of and delivered to the Holder of this Note a certificate
for the number of duly authorized, validly issued, fully paid and nonassessable
shares of Common Stock to which such Holder shall be entitled upon such
conversion.

                                       1



3.2. Automatic Conversion. In the event that the Common Stock trades at or in
excess of a price per share of $30.00 for a period of not less than twenty
consecutive Trading Days, this Note shall automatically be converted, without
any action on the part of the Holder or the Company, into a number of shares of
Common Stock equal to (x) the aggregate amount of principal of this Note then
outstanding divided by (y) the Conversion Price then in effect. If, pursuant to
Section 3.4 below, this Note becomes convertible into other shares or other
interests, this Note shall automatically be converted into such shares or other
interests if the quotient obtained by dividing the aggregate fair market value
of such shares or other interests (as determined in good faith by the Company
(or its successor)), by the number of shares of Common Stock into which this
Note was convertible immediately before the Subsequent Event (as defined below)
equals or exceeds $30.00 for a period of not less than twenty consecutive
Trading Days.

3.3. Adjustments of Conversion Price for Subdivisions, Stock Dividends,
Combinations or Consolidation of Common Stock. In the event the outstanding
shares of Common Stock shall be increased by way of stock issued as a dividend
for no consideration or subdivided (by stock split or otherwise) into a greater
number of shares of Common Stock, the Conversion Price then in effect shall,
concurrently with the effectiveness of such increase or subdivision, be
proportionately decreased. In the event the outstanding shares of Common Stock
shall be combined or consolidated, by reclassification or otherwise, into a
lesser number of shares of Common Stock, the Conversion Price then in effect
shall, concurrently with the effectiveness of such combination or consolidation,
be proportionately increased.

3.4. Subsequent Events. In the event of any recapitalization, consolidation,
merger or bankruptcy or declaration of insolvency of the Company or its
successor (each, a "Subsequent Event"), this Note shall thereafter be
convertible into the right to receive such shares or other interests (including,
without limitation, cash) as the Holder would have been entitled if this Note
had been converted immediately prior to such Subsequent Event.

3.5. No Impairment. The Company will not, by amendment of its charter or through
any reorganization, recapitalization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Company, but will at all times in good faith
assist in carrying out all such action as may be necessary or appropriate in
order to protect the conversion rights of the Holder of this Note.

3.6. Reservation of Shares. So long as any portion of this Note shall remain
outstanding, the Company shall at all times reserve and keep available, free
from preemptive rights, out of its authorized capital stock, for the purpose of
issuance upon conversion of this Note, the full number of shares of Common Stock
then issuable upon conversion of this Note. If the Company's Common Stock shall
be listed on any national stock exchange, the Company at its expense shall
include in its listing application all of the shares of Common Stock reserved
for issuance upon conversion of this Note (subject to issuance or notice of
issuance to the exchange) and will similarly procure the listing of any further
Common Stock reserved for issuance upon conversion of this Note at any
subsequent time as a result of adjustments in outstanding Common Stock or
otherwise.

3.7. Validity of Shares. The Company will from time to time take all such action
as may be reasonably required to assure that all shares of Common Stock which
may be issued upon conversion of this Note will, upon issuance, be legally and
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges with respect to the issuance thereof; and, without limiting the
generality of the foregoing, the Company agrees that it will from time to time
take all such action as may be reasonably required to assure that the par value
per share, if any, of the Common Stock is at all times equal to or less than the
lowest quotient obtained by dividing the then current principal amount of this
Note by the number of shares of Common Stock into which this Note can, from time
to time, be converted.

3.8. Representations of the Holder. The Holder represents and warrants to the
Company that the Holder is acquiring this Note and the shares of Common Stock
issuable upon conversion of this Note for the Holder's own account for
investment only and not with a view to distribution or resale of the Note or
shares of Common Stock issuable upon conversion of this Note. The Holder
represents that it is an "accredited investor" as such term is defined in Rule
501 under the Securities Act of 1933, as amended (the "Act"). The Holder
understands that this Note and the shares of Common Stock issuable upon
conversion of this Note are being issued to the Holder pursuant to an exemption
from the registration requirements of the Act and, accordingly, must be held
indefinitely by the Holder unless later transferred in transactions that are
either registered under the Act or exempt from registration. The Holder also
understands that the shares of Common Stock issuable upon conversion of this
Note will bear a legend similar to the legend set forth at the top of this Note.

4.       EVENTS OF DEFAULT.

         4.1.   Events of Default. Each of the following events is herein
referred to as an "Event of Default":

         4.1.1. Breach of Covenant. The Company shall fail to perform or observe

any other covenant, agreement or provision to be performed or observed by it
under this Note and such failure shall not be rectified or cured within 30 days
after actual knowledge of such failure by an executive officer of the Company.

         4.1.2. Bankruptcy, etc. The Company shall:

       (a) commence a voluntary case under Title 11 of the United States Code as
       from time to time in effect, or authorize, by appropriate proceedings of
       its board of directors or other governing body, the commencement of such
       a voluntary case;

       (b) have filed against it a petition commencing an involuntary case under
       such Title 11, which petition is not dismissed within 30 days after such
       filing;

       (c) seek relief as a debtor under any applicable law, other than such
       Title 11, of any jurisdiction relating to the liquidation or
       reorganization of debtors or to the modification or alteration of the
       rights of creditors, or consent to or acquiesce in such relief;

       (d) have entered against it any order by a court of competent
       jurisdiction (i) finding it to be bankrupt or insolvent, (ii) ordering or
       approving its liquidation, reorganization or any modification or
       alteration of the rights of its creditors, or (iii) assuming custody of,
       or appointing a receiver or other custodian for, all or a substantial
       part of its property; or

       (e) make an assignment for the benefit of, or enter into a composition
       with, its creditors, or appoint or consent to the appointment of a
       receiver or other custodian for all or a substantial part of its
       property.

       4.2. Remedies. Upon the occurrence and during the continuance of any
       Event of Default, the Holder may accelerate the maturity of this Note
       upon notice to the Company (and upon the occurrence of an Event of
       Default under Section 4.1.3 above, such maturity shall be automatically
       accelerated) and may exercise any remedies at law or in equity.

       4.3. Annulment of Defaults. An Event of Default shall not be deemed to be
       in existence or to have occurred for any purpose of this Note until the
       expiration of all grace periods under this note or if the Holder shall
       have waived such event in writing or stated in writing that the same has
