<PAGE>

shall be deemed approved when mutually accepted in writing by both Parties
through their respective Commercialization Committee representatives; provided
however, that if the Commercialization Committee representatives of a Party fail
to comment on, or otherwise indicate disagreement with, the minutes provided by
the other Party in writing within fifteen (15) days of receipt, then the
receiving Party shall be deemed to have approved such minutes.

         4.3 Commercialization Program. Each of the Parties shall use
commercially reasonable efforts in carrying out its obligations under the
Commercialization Program as determined by the Commercialization Committee. In
order to establish and maintain the largest market possible for each Product,
under the direction of the Commercialization Committee, InterMune shall direct,
all the marketing, sales, promotion, operational and technical personnel,
know-how, equipment, supplies and facilities necessary to carry out the
Commercialization Program, including without limitation appropriate staffing
levels on an experienced, well-trained sales force dedicated exclusively to the
Commercialization Program. InterMune shall be responsible for and shall
commercially launch each of the Products at the direction of the
Commercialization Committee. ** In addition, the Commercialization Committee
shall set reasonable minimum annual sales performance obligations prior to the
launch of each Product in each of the countries within the territory.

         4.4 Reporting; Audits. The reporting requirements and audit rights for
the Commercialization Program are set forth in Section 3 and Section 5,
respectively, of Exhibit A.

         4.5 Notwithstanding any other provision of this Agreement to the
contrary, in the event InterMune has taken any action with respect to
commercialization of any Product that materially jeopardizes the
commercialization of such Product and MoliChem can produce evidence that such
InterMune actions have materially jeopardized the commercialization of any
Product, and InterMune has failed to cure such action within ninety (90) days
after receiving notice from MoliChem that such actions have materially
jeopardized the commercialization of the Product, then all rights to control the
commercialization with respect to such Product shall thereafter be directed by
MoliChem.

5.       Supply and Manufacturing.

         5.1 At the direction of the Development Committee, MoliChem shall
manage the planning, agreements and operations concerning the supply and
manufacture of the Products for the Development Program; provided however, all
manufacturing specifications shall be established by the Development Committee.

         5.2 At the direction of the Development Committee, MoliChem shall also
manage all matters concerning the supply and manufacture of any Product for the
Commercialization Program, in accordance with the specifications established by
the Development Committee.

         5.3 Although MoliChem shall manage the manufacture of the Products,
qualified personnel of InterMune shall participate and collaborate in the supply
and manufacture of the Products according to the plan set forth by the
Development Committee and for so long as MoliChem continues to manage the
manufacture of the Products, InterMune shall have a right to



                                      E-34

<PAGE>

audit the manufacture of Moli1901 in accordance with generally accepted audit
procedures for similar manufacturing processes.

         5.4 In the event MoliChem is unwilling or unable to manufacture any
Product, it may request that the Development Committee take responsibility for
the manufacture of such Product. All costs of manufacturing shall be borne by
InterMoli.

         5.5 Notwithstanding any other provision of this Agreement to the
contrary, in the event MoliChem has taken any action with respect to
manufacturing any Product that materially jeopardizes the commercialization of
such Product and InterMune can produce evidence that such MoliChem actions have
materially jeopardized the commercialization of any Product, and MoliChem has
failed to cure such action within ninety (90) days after receiving notice from
InterMune that such actions have materially jeopardized the commercialization of
the Product, then all rights to control the manufacturing with respect to such
Product shall thereafter be directed by InterMune.

6.       PAYMENTS

         6.1 Initial Payment. Upon the Effective Date and in partial
consideration for the rights granted to InterMune herein, InterMune shall make a

7.       INTELLECTUAL PROPERTY MATTERS; PATENTS

         7.1 Ownership. All Joint Intellectual Property shall be jointly owned
by the Parties with each Party owning an undivided one-half interest. For all
other intellectual property developed pursuant to this Agreement, inventorship
shall be determined in accordance with the U.S. patent or other applicable laws.
MoliChem shall own all inventions not related to Moli1901 that have been
conceived or reduced to practice under this Agreement solely by MoliChem's
employees, consultants or others with an obligation to assign their rights to
MoliChem. Intermune shall own all inventions not related to Moli1901 that have
been conceived or reduced to practice under this Agreement solely by InterMune's
employees, consultants or others with an obligation to assign their rights to
InterMune. InterMune shall grant MoliChem a perpetual irrevocable, royalty free,
non- exclusive license to any and all intellectual property rights that are not
Joint Intellectual Property and arise from the Development Program or
Commercialization Program that relate to Moli1901 or any other lantibiotic
technology of MoliChem (including but not limited to manufacturing, formulation
and packaging technology), and shall execute at the request of MoliChem such
reasonable documents in furtherance of the foregoing license.

         7.2 Patent Filing, Prosecution and Maintenance.

         (a) MoliChem shall have the first right, but not the obligation, to
file applications for the Development Patents and to prosecute and maintain such
Development Patents in such countries as selected by the Development Committee
or the Commercialization Committee, as the case may be, at InterMoli's expense.
MoliChem shall reasonably consider any recommendations provided by InterMune
regarding the filing and/or prosecution of such Development Patents, but the
final decision as to the filing and/or prosecution matters shall rest with
MoliChem.

         (b) In the event that InterMune desires that MoliChem file and
prosecute a patent application claiming a particular invention in the
Development Technology, and MoliChem does not file such a patent application
within one hundred twenty (120) days of such request, or decides to abandon
prosecution of such a filed application, then InterMune may thereafter file,
prosecute and/or maintain the Patent(s) claiming such particular inventions, at
InterMune's expense. In such event, MoliChem shall cooperate reasonably with
InterMune in such efforts.

         (c) In the event that pursuant to the terms of Section 11, MoliChem's
rights in any of the Development Patents are subject to an exclusive license to
InterMune, even as to MoliChem, MoliChem's rights to control the prosecution of
such Development Patents shall be as set forth in Sections 7.2(a) and 7.2(b) of
this Agreement; provided however, all expenses related to such prosecution shall
be solely the responsibility of InterMune, and InterMune will promptly reimburse
MoliChem for any such expenses. InterMune shall have the right to review and
comment on all aspects of such prosecution and to direct the prosecution of such
Development Patents in the event MoliChem is no longer or able or willing to
continue with the prosecution of any of the Development Patents. Notwithstanding
the foregoing, in the event MoliChem has taken any action with respect to the
prosecution of the Development Patents subject to an exclusive license in
accordance with the terms of this Section, or MoliChem has taken any action with
respect to the prosecution of the Development Patents, subject to such exclusive
license that materially jeopardizes the commercialization of such exclusively
licensed Product, and InterMune can produce evidence



                                      E-36

<PAGE>

that such MoliChem actions have materially jeopardized the commercialization of
such exclusively licensed Product, and MoliChem has failed to cure such action
within ninety (90) days after receiving notice from InterMune that such actions
have materially jeopardized the commercialization of the Product, and all of the
claims pending in such Patent or Patent application relate solely to the
exclusively licensed Product, then all rights to control the prosecution of the
Development Patents subject to such exclusive license shall thereafter be
directed by InterMune; provided however, this provision shall not invoke any
transfer of ownership of such Development Patents.

         7.3 Cooperation. Each Party agrees to cooperate with the other and take
all reasonable additional actions as may be reasonably required to achieve the
intent of this Section 7, including, without limitation, the execution of
necessary and appropriate instruments and documents.

         7.4 Infringement of Third-Party Patents. In the event that a Third
Party files an action against a Party alleging that such Party's activities
under this Agreement infringe such Third Party's patent rights, such Party shall
give written notice to the other Party, and the Parties will consult and
cooperate on the best course of action. The Party that was sued shall have the
right to defend itself against such action, and the other Party shall provide
all reasonable assistance in such defense.

         7.5 Infringement of Development Patents. If either Party becomes aware
that a Third Party is infringing any rights in the Development Patents, such
Party shall give written notice to the other Party describing in detail the
nature of such infringement. MoliChem shall have the initial right to enforce
the Development Patents against such Third Party infringer. InterMune agrees to
provide MoliChem all reasonable assistance, at InterMoli's expense, in such
enforcement, including without limitation being joined as a party to the suit
where appropriate. In the event that MoliChem fails to institute an infringement
suit or take other reasonable action in response to such infringement within one
hundred twenty (120) days after its receipt of notice of such infringement,
InterMune shall have the right, but not the obligation, to institute such suit
or take other appropriate action in its own name to enforce the Development
Patents. Regardless of which Party brings an enforcement action under this
Section 7.5, the Party not bringing the action shall have the right to
participate in such action at its own expense with its own counsel. Any damages
or other recovery, whether by settlement or otherwise, from an action hereunder
to enforce the Development Patents shall first be applied pro rata to each Party
to pay the costs and expenses of participating in such action, and any remaining
amount shall be paid to the Party conducting the action.

         7.6 No Other Technology Rights. Except as otherwise provided in this
Agreement, under no circumstances shall a Party, as a result of this Agreement,
obtain any ownership interest or other right in any technology, know-how,
Patents, products, compounds, materials, vaccines, antibodies, cell lines or
cultures, or animals of the other Party, including items owned, controlled or
developed by the other, or transferred by the other to such Party at any time
pursuant to this Agreement. It is understood and agreed by the Parties that this
Agreement does not grant to either Party any license or other right in basic
technology of the other Party except to the extent necessary to enable the
Parties to carry out their obligations under this Agreement for the development
and commercialization of Products.

officers, directors, agents and employees from and against any and all
liabilities, damages, judgments, awards or costs of defense (including without
limitation reasonable attorneys' fees, expenses to defend and amounts paid in
settlement of any action) (collectively, "Losses") arising from any Third Party
claim resulting directly or indirectly from InterMune's breach of any of its
covenants or representations and warranties hereunder, or InterMune's negligence
or wrongdoing, but only to the extent that such Losses do not result from
MoliChem's breach of any of its covenants or representations and warranties
hereunder or MoliChem's negligence or wrongdoing.

         10.2 By MoliChem. Subject to InterMune's compliance with Section 10.4,
MoliChem hereby agrees to indemnify, defend and hold harmless InterMune and its
officers, directors, agents and employees from and against any and all Losses
from any Third Party claim resulting directly or indirectly from MoliChem's
breach of any of its covenants or representations and warranties hereunder, or
MoliChem's negligence or wrongdoing, but only to the extent that such Losses do
not result from InterMune's breach of any of its covenants or representations
and warranties hereunder or InterMune's negligence or wrongdoing.

         10.3 Joint Liability. The Parties hereby agree that the Parties shall
be jointly liable for any third party claims made against either Party as a
result of the actions taken pursuant to the Development Program or the
Commercialization Program, provided that such actions have been specifically
authorized by either the Development Committee or the Commercialization
Committee, except to the extent those claims are based on the other Party's
breach of any of its covenants or representations and warranties hereunder or
the other Party's negligence or wrongdoing.

         10.4 Notice and Procedures. In all cases where one Party seeks
indemnification by the other under this Section 10, the Party seeking
indemnification shall promptly notify the indemnifying Party of receipt of any
claim or lawsuit covered by such indemnification obligation and shall cooperate
fully with the indemnifying Party in connection with the investigation and
defense of such claim or lawsuit. The indemnifying Party shall have the right to
control the defense, with counsel of its choice, provided that the
non-indemnifying Party shall have the right to be represented by advisory
counsel at its own expense. The indemnifying Party shall not settle or dispose
of the matter in any manner, which could negatively and materially affect the
rights or liability of the non-indemnifying Party without the non-indemnifying
Party's prior written consent, which shall not be unreasonably withheld or
delayed.

         10.5 Insurance. Each Party, at its own expense, shall maintain
comprehensive general liability insurance and clinical trial insurance coverage
in amounts reasonable and customary in the industry, but not less than

determined by the Commercialization Committee prior to the first commercial sale
or distribution of Product. The University of North Carolina and MoliChem shall
be named in such policy as additional insured parties. Each Party shall provide
documentation that such coverage exists upon request of the other Party. Each
Party shall maintain such insurance for so long as it continues to research,
develop, manufacture, commercialize, and market Products, and thereafter for so
long as it customarily maintains insurance for itself covering similar
activities with its other similar products.

         12.5 Limitation of Liability. In no event will either Party be liable
to the other Party for any indirect, collateral, consequential, special or
punitive damages or for any lost profits of the other Party, however caused and
on any theory of liability, arising out of the performance or failure to perform
any obligations set forth herein, except for those damages caused by a Party's
gross negligence, omissions or willful malfeasance.

         12.6 Consents Not Unreasonably Withheld or Delayed. Whenever provision
is made in this Agreement for either Party to secure the consent or approval of
the other, that consent or approval shall not unreasonably be withheld or
delayed, and whenever in this Agreement provisions are made for one Party to

         12.7 Independent Contractors. The status of the Parties under this
Agreement shall be that of independent contractors. Neither Party shall have the
right to enter into any agreements on behalf of the other Party, nor shall it
represent to any person that it has any such right or authority. Nothing in this
Agreement shall be construed as establishing a partnership or joint venture
relationship between the Parties.

         12.8 Maintenance of Records. Each Party shall keep and maintain all
records required by law or regulation with respect to the Product and shall make
copies of such records available to the other Party upon request.

         12.9 United States Dollars. References in this Agreement to "Dollars"
or "$" shall mean the legal tender of the United States of America.

         12.10 Assignment. Neither Party to this Agreement may assign or
transfer this Agreement or any rights or obligations hereunder without the prior
written consent of the other Party. Notwithstanding the foregoing, either Party
may assign or transfer this Agreement to a successor of a controlling interest
of such Party. Any permitted successor or assignee of rights and/or obligations
hereunder shall, in writing to the other Party, expressly assume performance of
such rights and/or obligations. This Agreement shall be binding upon and shall
inure to the benefit of each Party's permitted successors-in-interest and
permitted assigns. Any assignment or attempted assignment by either Party in
violation of the terms of this Section 12.10 shall be null and void and of no
legal effect.

         12.11 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.

         12.12 Further Actions. Each Party agrees to execute, acknowledge and
deliver such further instruments, and to do all such other acts, as may be
necessary or appropriate in order to carry out the purposes and intent of this
Agreement.

         12.13 Severability. If any one or more of the provisions of this
Agreement is held to be invalid or unenforceable, the provision shall be
considered severed from this Agreement and shall not serve to invalidate any
remaining provisions hereof. The Parties shall make a good faith effort to
replace any invalid or unenforceable provision with a valid and enforceable one
such that the objectives contemplated by the Parties when entering this
Agreement may be realized.

         12.14 Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event of an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring any Party by virtue of the authorship of any of
the provisions of this Agreement.

         12.15 Headings. The headings for each article and section in this
Agreement have been inserted for convenience of reference only and are not
intended to limit or expand on the meaning of the language contained in the
particular article or section.

         12.16 No Waiver. Any delay in enforcing a Party's rights under this
Agreement or any waiver as to a particular default or other matter shall not
constitute a waiver of such Party's rights to the future enforcement of its
rights under this Agreement, excepting only as to an express written and signed
waiver as to a particular matter for a particular period of time.

         12.17 Governing Law; Jurisdiction and Venue. This Agreement will be
governed and construed in accordance with the laws of the State of New York. No
lawsuit pertaining to any matter arising under or growing out of this Agreement
shall be instituted in any jurisdiction other than in the state of the defendant
to any such action and the Parties consent to exclusive jurisdiction before the
federal or state courts of state of the defendant to any such action.

         12.18 Change of Law. It is the intention of the Parties to conform
strictly to all Applicable Laws, including but not limited to the Anti-kickback
Statute. Accordingly, upon the written request of either Party, the
Commercialization Committee shall engage at InterMoli's expense, a qualified and
experienced health care regulatory counsel acceptable to both Parties to deliver
an opinion that to the effect that, based upon the interpretation of prevailing
legal and regulatory authority, the compensation arrangement described in
Exhibit A is fully compliant with all Applicable Laws. In the event that the
Commercialization Committee is unable to provide such requested legal opinion
or the Commercialization Committee provides such legal opinion but it is
qualified and not otherwise unequivocal in support of the compliance of the
compensation arrangement described in Exhibit A, then in such event, the
Parties, in coordination with the Commercialization Committee, shall negotiate
in good faith such changes to the structure and terms of the transactions
provided for in this Agreement as may be necessary to make these arrangements,
as restructured, lawful under Applicable Laws, without materially disadvantaging
either Party, and this Agreement shall be deemed reformed in accordance with the
terms negotiated by the Parties. In the event that the Commercialization
Committee is unable to agree on appropriate adjustments, then the matter shall
be resolved pursuant to Section 12.2.

         12.19 Legal Fees. If any dispute arises between the Parties with
respect to the matters covered by this Agreement which leads to a proceeding to
resolve such dispute, the prevailing party in such proceeding shall be entitled
to receive its reasonable attorneys' fees, expert witness fees and out-of-pocket
costs incurred in connection with such proceeding, in addition to any other
relief it may be awarded.

         12.20 Injunctive Relief. A breach of any of the promises or agreements
contained in this Agreement may result in irreparable and continuing damage to a
Party for which there may be no adequate remedy at law, and each Party is
therefore entitled to seek injunctive relief as well as such other and further
relief as may be appropriate. The obligations provided under Section 8 of this
Agreement are acknowledged as necessary and reasonable in order to protect each
Party and its business, and the Parties expressly agree that monetary damages
would be inadequate to compensate either Party for the breach thereof.
Accordingly, each Party agrees and acknowledges that any such violation or
threatened violation will cause irreparable injury to the other Party and that,
in addition to any other remedies that may be available, in law, in equity or
otherwise, each Party shall be entitled to obtain injunctive relief against the
breach or threatened breach by the other Party of Section 8, without the
necessity of proving actual damages.
