either Party in the event of the material breach or default by the other Party
of the terms and conditions hereof; provided, however, the other Party shall

Party in the notice of termination), Catalytica shall manufacture and ship, and
Customer shall purchase in accordance with the provisions hereof, any and all
amounts of Product ordered by Customer hereunder prior to the date on which such
notice is given.
              (b) In addition, upon expiration or termination of this Agreement,
other than termination by Customer pursuant to Section 12.3 or 12.4 hereof, (i)
at Catalytica's option, Customer shall purchase from Catalytica at Catalytica's
Acquisition Cost all materials acquired by Catalytica hereunder in the ordinary
course of business prior to the date of expiration of the Agreement or on which
notice of termination is given for the manufacture of Product, provided that
such materials are not then-currently usable by Catalytica or cannot be returned
for a full refund to supplier(s) or a partial refund to supplier(s) with
Customer paying the balance due to Catalytica, (ii) at Catalytica's option,
Customer shall purchase from Catalytica all work-in-progress for the Product at
Catalytica's cost, (iii) at Catalytica's option, Customer shall purchase all

to satisfy existing purchase orders, provided that (i), (ii), (iii) and/or (iv)
are substantiated by Customer's purchase orders [*              *]. Customer
shall compensate Catalytica for any and all technology transfer and other
capital costs that were incurred and not recovered by Catalytica and that were
agreed to by the Parties in the development plan provided that these costs were
incurred at agreed timing in accordance with the development plan. At Customer's
sole option, Catalytica will either cause to be destroyed or deliver to a
facility designated by Customer any of the above materials so purchased by
Customer. Catalytica will use its commercially reasonable efforts to reduce such
inventory and manage such purchases so as to minimize the payments required of
Customer under this Section 12.5(b).
              (c) Upon expiration or termination of this Agreement, the
obligations of confidentiality and restrictions on use of Confidential
Information under Article 15 hereof shall survive for the period provided
therein.
              (d) Upon expiration or termination of this Agreement (other than
as a result of Customer's breach of any of its payment obligations hereunder),

Customer shall reimburse Catalytica at a reasonable hourly rate for, any and all
transfer of methods, tests and processes necessary for Customer to manufacture
the Product at an alternate site.

Customer's designated carrier by Catalytica shall fail to conform with any
warranty set forth herein relating to quality and/or the Specifications,
Customer shall reject such Product by giving written notice to Catalytica within

documentation with shipment, i.e., Certificate of Analysis. Any notice given
hereunder shall specify the manner in which the Product fails to meet such
warranty or the Specifications. If it is determined by agreement of the Parties

Customer expects to make a claim against Catalytica with respect to damaged or
otherwise nonconforming Product, Customer shall not dispose of such Product
without written authorization and instructions of Catalytica either to dispose
of the Product or to return the Product to Catalytica. If the Product is

by any such compromise or settlement absent its prior consent, which shall not
be unreasonably withheld or delayed. The Indemnitee shall have the right, but
not the obligation, to be represented by counsel of its own selection and at its
own expense.

such Catalytica Confidential Information to government or other regulatory
authorities to the extent that such disclosure is legally necessary to obtain
authorizations to conduct clinical trials with and to market commercially the
Product, provided Customer is otherwise entitled to engage in such activities
under this Agreement. Upon Catalytica's request (made no more frequently than
once each calendar year), Customer shall advise Catalytica of the Catalytica
Confidential Information provided to governmental authorities and notice of the
particular authorities to which such Information has been given. Catalytica or
its Affiliates may disclose such Customer Confidential Information to government
or other regulatory authorities to the extent that such disclosure is reasonably
necessary to obtain patents for new inventions that Catalytica owns pursuant to
Section 16.2 provided that Customer consents to such disclosure in writing (such
consent not to be unreasonably withheld or delayed). All other disclosures
require the written permission of the non-disclosing Party which may be granted
or withheld in the absolute discretion of the non-disclosing Party. The Customer
may additionally disclose (i) the existence of and non-material terms of this
Agreement in connection with its financing and licensing activities and (ii)
material aspects of this Agreement to prospective licensees provided that such
prospective licensees have a legal obligation to protect the confidentiality of
said disclosure.

other intellectual properties and other assets, including but not limited to
procedures and techniques, computer technical expertise, software, and certain
technical expertise and conceptual expertise in the area of drug processing and
manufacturing, which have been independently developed by Catalytica or its
Affiliates without the benefit of any information provided by Customer

inventions, technology and information, whether patentable or not (other than
those described in Section 16.1) conceived, reduced to practice or created
solely by Catalytica and/or its agents during the performance of this Agreement
shall be owned by Catalytica; provided, however, that Catalytica shall attempt
without compromising its other obligations hereunder to minimize the use of any
such Catalytica-owned technology in the manufacture of the Product.

patentable or not (other than those described in Section 16.1), conceived,
reduced to practice or created solely by Customer and/or its agents during the
performance of this Agreement shall be owned by Customer. If the Parties'
efforts under this Agreement result in inventions which are jointly owned by
Catalytica and Customer because employees or agents for each of Catalytica and
Customer make inventive contributions thereto, that is employees or agents of
both Parties would be or are properly named as co-inventors under the laws of
the United States on any patent application claiming such inventions, then each
Party shall have full rights to exploit such jointly owned inventions for its

                                      -27-

own commercial purposes without any obligation to the other Party. Each Party
shall be responsible for the costs of filing, prosecution and maintenance for
patents and patent applications on its owned technology and inventions and the
Parties shall share equally the patenting costs of any jointly owned inventions.
In this regard, any decision to file for patent coverage on jointly owned
inventions, shall be mutually agreed upon, and the Parties will select a
mutually acceptable patent counsel to file and prosecute applications based on
such joint inventions.

obligations under this Agreement in case such failure or delay is due to any
condition beyond the reasonable control of the affected Party including, without

fire, civil disorder, explosion, accident, flood, sabotage, lack of or inability
to obtain adequate fuel, power, materials, labor, containers, transportation,
supplies or equipment, compliance with governmental requests, laws, rules,

continuous period of six (6) months and (ii) seek an alternate supplier of the
Product during the continuation of, and only during the continuation of, such a
Force Majeure Event unless Customer can only secure an alternate supplier for a
time period in excess of the Force Majeure Event period, in which case Customer
will resume its exclusive supply relationship with Catalytica at the end of such

Party shall give notice of the same

the cause relied upon, and upon the giving of such notice the obligations of the
Party giving the notice will be suspended during the continuance of the Force
Majeure Event; provided, however, such Party shall take commercially reasonable
steps to remedy the Force Majeure Event with all reasonable dispatch. The
requirement that Force Majeure Event be remedied with all reasonable dispatch
shall not require the settlement of strikes or labor controversies by acceding
to the demands of the opposing party.

              21.1 Independent Contractors. The relationship between Customer
                   -----------------------

provided) within ten (10) business days of such request. In the event either
Party is to review or approve any information, documentation, data or samples
prepared or supplied by or on behalf of the other Party, the replying Party

         21.3 Assignment; Subcontractors. The Customer may assign this Agreement
              --------------------------
to any party listed on the attached Exhibit 8. This Agreement may not be
otherwise assigned or transferred by either Party without the prior written
consent of the other Party, which consent shall not be unreasonably withheld;
provided, however, either Party may, without such consent, assign this Agreement
--------  -------
(a) in connection with the transfer or sale of all or substantially all of the
assets of such Party or the line of business of which this Agreement forms a
part, (b) in the event of the merger or consolidation of a Party hereto with
another company, or (c) to any Affiliate of the assigning Party. Any purported
assignment in violation of the above shall be void. Any permitted assignee shall
assume all obligations of its assignor under this Agreement. No assignment shall
relieve either Party of responsibility for the performance of any obligation
which accrued prior to the effective date of such assignment. At its option,
Catalytica may use subcontractors to perform any part of this Agreement,
provided such subcontractors are bound by a confidentiality agreement with
Catalytica and are subject to all quality and all other standards and
obligations as may be imposed on Catalytica under this Agreement (for example,
without limitation, Catalytica may, at its option, have cleaning
verification/methods validation performed by a CGMP compliant laboratory).
              21.4 Continuing Obligations. Termination, assignment or expiration
                   ----------------------
of this Agreement shall not relieve either Party from full performance of any
obligations incurred prior thereto.
              21.5 Waiver. Neither Party's waiver of any breach or failure to
                   ------
enforce any of the terms and conditions of this Agreement, at any time, shall in
any way affect, limit or waive such Party's right thereafter to enforce and
compel strict compliance with every term and condition of this Agreement.
              21.6 Severability. Each Party hereby expressly agrees that it has
                   ------------
no intention to violate any public policy, statutory or common laws, rules,
regulations, treaty or decision of any government agency or executive body
thereof of any country or community or association of countries; that if any
word, sentence, paragraph, clause or combination thereof in this Agreement is
found by a court or executive body with judicial powers having jurisdiction over
this Agreement or either Party hereto, in a final unappealed order, to be in
violation of any such provisions in any country or community or association of
countries, such words, sentences,

                                      -32-
<PAGE>

paragraphs, clauses or combination shall be inoperative in such country or
community or association of countries and the remainder of this Agreement shall
remain binding upon the Parties, so long as enforcement of the remainder does
not violate the Parties' overall intentions in this transaction.

                Regulatory Affairs for reference during inspections.

         8.3.7  C*P will provide support for POZEN in regards to proposing
                appropriate CMC regulatory strategies and identifying potential
                regulatory consequences for issues involving drug products.

         8.4.3  C*P will permit representatives of POZEN Quality to conduct
                preparatory audits either for initiation of GMP manufacture of
                the PRODUCTS or for preapproval inspections (PAI).

         8.4.4  C*P will permit representatives of POZEN Quality to conduct
                audits to address significant product quality or safety
                problems.

         8.4.5  C*P will permit representatives of POZEN Quality to perform one
                standard GMP compliance audit per year not to exceed three
                working days and two groups of auditors. This includes audits
                required by POZEN's commercial partners.

     8.5 Audit Closeout

         8.5.1  An exit meeting will be held with representatives of C*P and
                POZEN to discuss significant audit observations.

         8.5.2  POZEN will provide a written report of all observations within
                30 days to C*P. Within 30 days of the audit report receipt, C*P
                will provide a written response to all findings that details
                corrective action to be implemented. C*P will follow up to
                ensure that all corrective actions are implemented.

9   DISPUTE RESOLUTION
    ------------------

     9.3 Non-Conformity Dispute

         9.1.1  In the event that a dispute arises between C*P and POZEN in the
                nonconformity of a batch of the PRODUCTS, the heads of Quality
                from both companies shall in good faith promptly attempt to
                reach an agreement. Whatever the outcome, POZEN Quality retains
                the absolute right to determine product release status.
                Financial liability is determined in the Definitive Agreement.

     9.2 Test Result Dispute

         9.2.1  In the event that a dispute arises between C*P and POZEN in the
                testing performed by C*P for the PRODUCTS, the resolution will
                proceed in stages. The first stage requires direct communication
                between analysts from both parties to determine that the methods
                of analysis are the same and are being executed in the same
                manner at both sites. Second, carefully controlled and split
                samples should be sent from one site to another in an attempt to
                reach agreement. Should there be a failure to achieve
                resolution, analysts from both parties will be required to meet
                to work through the analysis of a mutually agreeable sample. If
                these actions fail to achieve resolution, and only after these
                avenues have been exhausted, a qualified referee laboratory will
                be used to achieve resolution. This laboratory must be agreeable
                to both parties prior to use. The results from this referee
                laboratory will be used as final authority to determine
                responsibilities, but whatever the outcome, POZEN retains the
                right to determine product release status. Financial liability
                is determined in the Definitive Agreement.

10.      CHANGE MANAGEMENT
         -----------------

10.1     Controlled Documentation

         10.1.1 All manufacturing, testing, and storage operations performed by
                C*P for the PRODUCTS will have POZEN Quality review and written
                approval within five business days of notification.

         10.1.2 Any significant changes as described in C*P Change Control
                Procedure or to this agreement will be mutually agreed upon in
                writing prior to implementation. All required regulatory
                approvals will be obtained prior to implementation.

10.2     Change Control

         10.2.1 Changes to the controlled documents or to validated equipment
                and systems specific to the PRODUCTS must have POZEN Quality
                written approval, within five business days of notification.

         10.2.2 Administrative changes to the controlled documents (e.g., typo
                corrections, formatting) do not require POZEN Quality written
                approval prior to implementation, but these changes must be
                submitted to POZEN Quality in a timely manner for review and
                approval.

11.      PRODUCT AND PROCESS VALIDATION
         ------------------------------

         11.1   Process - C*P is responsible for ensuring that the manufacturing
                process is validated. The validation should ensure that the
                process is capable of consistently achieving the PRODUCTS
                acceptance specification.

         11.2   Cleaning Validation - C*P is responsible for ensuring that
                adequate cleaning is carried out between batches of different
                products to prevent contamination. POZEN will provide
                information (i.e. LD50, toxicity, solubility, batch size, fill
                volume, product min dose/70Kg patient) to establish cleaning
                limits. The cleaning procedure and analytical methodology will
                be reviewed before the first product batches are made.

         11.3   Equipment, Computer, Facility, and Utilities Qualification - C*P
                is responsible for all equipment, computer, facility, and
                utility qualification activities associated with the PRODUCTS.

         11.4   Laboratory Qualification - C*P is responsible for ensuring that
                all laboratories are in compliance with cGMP's and are qualified
                in all of the methodology associated with the PRODUCTS. If
                analytical work is performed at C*P then the POZEN will also
                provide any existing analytical documentation to assist in
                methods transfer or methods validation. In addition, if
                analytical work is not performed at the Greenville site, C*P may
                elect to perform an audit on vendors to be used for analytical
                testing.

12.      ANNUAL PRODUCT REVIEW, ANNUAL REPORT AND DRUG LISTING
         -----------------------------------------------------

12.1     Annual Product Review

         12.1.1 C*P will perform an Annual Product Review for the PRODUCTS and
                will issue a report to POZEN. This report will cover all
                manufacturing, testing, and storage activities performed by C*P.
                It will be a review of any changes at C*P in the manufacturing,
                testing, storage or validation of the PRODUCTS in the previous
                calendar year and a summary of lots made, released, and
                rejected. Also, control charting or trend analysis of key
                product parameters will be performed. Any abnormalities will be
                explained in the annual review.

         12.1.2 POZEN is responsible for preparing any Annual Report as required
                by applicable regulations, including 21 CFR 314.7(g)(3),
                314.81(b)(2), and/or 601.12(d), (f)(3). At least 90 calendar
                days before the Annual Report due date, POZEN shall request in
                writing from C*P the chemistry, manufacturing, and controls data
                required for submission of the Annual Report. C*P will provide
                the requested information to POZEN within 30 days.

     12.2 Drug Listing

         12.2.1 C*P is responsible for drug listing as the manufacturer of the
                PRODUCTS, while POZEN is responsible for drug listing as the
                distributor of the PRODUCTS. POZEN will provide C*P with all
                required information needed by them for their listing. POZEN
                will notify C*P of the scheduled PRODUCTS launch date.
