to from time to time to reflect to the manufacturing requirements of Vivus' MUSE

an application for regulatory approval. In case of any official monograph or
regulatory agency requirement conflicts with the current USP and European
Pharmacopoeia requirements for the Product and Spolana's manufacturing and
control process of Product described in the DMF, parties will consult to seek a
mutually acceptable solution. All Product supplied by Spolana shall be
manufactured in accordance with current GMP manufacturing and record keeping
procedures and ISO 9000 regulatory requirements and record keeping procedures at

the manner in which all or part of such shipment fails to meet the foregoing
requirements. If rejection is based on grounds of contamination or Product not

accompanied by a satisfactory sample returned to Spolana to verify such
non-conformity. If Vivus rejects a shipment before the date on which payment
therefor is due, it may

withhold payment for such shipment or the rejected portion thereof. The
warranties given by Spolana in Article 5 below shall survive any failure to
reject by Vivus under this Section 3.3.

         3.4 Returns and Settlement of Claims. Spolana shall be obliged to
respond in writing to Vivus accepting or refusing a rejection notice from Vivus
[*] from the date of receipt of such rejection notice in accordance with Section
3.3 above. In case of a disagreement between the parties, the claim shall be
submitted for tests and decision to an independent testing organization which
meets appropriate GMP or consultant of recognized repute within the United
States pharmaceutical industry mutually agreed upon by the parties (the
"Laboratory"), the appointment of which shall not be unreasonably withheld or
delayed by either party. The determination of such entity with respect to all or
part of any shipment of Product shall be final and binding upon the parties. The
fees and expenses of the Laboratory making such determination shall be paid by
the party against which the determination is made (i.e., the party whose
argument is rejected by the Laboratory). Products accepted by Spolana as not
meeting the applicable requirements and Specifications or so decided by the
Laboratory shall be returned by Vivus to Spolana. Spolana shall use its best
efforts to replace the quantities of Product returned by Vivus within the
shortest possible time, [*] from the return of such quantities. The replacement
of returned Product shall have priority over the supply of Product ordered for
shipment, [*] or any time after the return of the rejected quantity to Spolana.
Without limiting the remedies of Vivus, if Spolana fails to replace returned
Product within [*] days from the date Product is returned to Spolana, Vivus
shall have the right (i) to cancel such replacement shipment by written notice
and (ii) to reclaim immediately (either through refund or setoff, at Vivus'
discretion) the amounts paid pursuant to Section 2.7 above for the Product that
was returned but not replaced, if such payment for such Product had already been
made to Spolana.

         3.5. Presence At Facility. Upon reasonable notice given by Vivus to
Spolana and at reasonable frequency, Vivus shall have the right to assign a
reasonable number of employees or consultants of Vivus to inspect and audit the
Facility at which Product is manufactured in order to verify Spolana's
compliance with the current GMP and other agreed requirements, provided, however
that (a) such employees or consultants shall not unreasonably interfere with
other activities being carried out at the Facility, and (b) that such employees
or consultants shall observe all rules and regulations applicable to visitors
and to individuals employed at the Facility. It is understood that as of the
Effective Date Vivus has engaged Forum (Holdings) Limited ("Forum") pursuant to
that certain agreement dated September 26, 1996 pursuant to which Forum agreed
to assist Vivus in ensuring, by aiding Spolana, that Spolana meets and maintains
current GMP and requirements necessary for the sale of Product throughout the

         7.1 Confidential Information. The parties may from time to time
disclose to each other Confidential Information. "Confidential Information"
shall mean any information disclosed by one party to the other party hereto
which if disclosed in tangible form is marked "confidential" or with other
similar designation to indicate its confidential or proprietary nature or if
disclosed orally is indicated orally to be confidential or proprietary by the
party disclosing such information at the time of such disclosure and is
confirmed in writing as confidential or proprietary by the disclosing party
within [*] after such disclosure. Notwithstanding the foregoing, Confidential
Information shall not include any information that, in each case as demonstrated
by written documentation: (i) was already known to the receiving party, other
than under an obligation of confidentiality, at the time of disclosure; (ii) was
generally available to the public or otherwise part of the public domain at the
time of its disclosure to the receiving party; (iii) 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; (iv) was subsequently lawfully disclosed to the receiving party by a
person other than the disclosing party; or (v) was developed by the receiving
party without reference to any Confidential Information of the disclosing party.

         7.2  Confidentiality.  Each party hereby agrees:  (i) to hold and 
maintain in strict confidence all Confidential Information of the other party;
and (ii) not to use or disclose any

Confidential Information of the other party except to those employees and
consultants who have a need to know, as otherwise permitted by this Agreement,
or as may be necessary to exercise its rights or perform its obligations under
this Agreement; provided that each party to whom Confidential Information is
disclosed agrees to be bound by the same terms regarding the disclosure and use
of Confidential Information as set forth in this Article 7. Nothing contained in
this Article 7 shall prevent either party from disclosing any Confidential
Information of the other party to (a) regulatory agencies for the purpose of
obtaining approval to distribute and market the Product; provided, however, that
all reasonable steps are taken to maintain the confidentiality of such
Confidential Information to be disclosed; (b) to accountants, lawyers or other
professional advisors or in connection with a merger, acquisition or securities
offering, subject in each case to the recipient entering into an agreement to
protect such Confidential Information from disclosure; or (c) is required by law
or regulation to be disclosed; provided, however, that the party subject to such
disclosure requirement has provided written notice to the other party promptly
upon receiving notice of such requirement in order to enable the other party to
seek a protective order or otherwise prevent disclosure of such Confidential
Information.

        7.3 Return of Confidential Information. Upon termination or expiration
of this Agreement, each party shall return all Confidential Information in its
possession that was received from the other party.

or interpret this Agreement.

         11.9 Non-Waiver. Any waiver of the terms and conditions hereof must be
explicitly in writing. The waiver by either of the parties of any breach of any
provision hereof by the other shall not be construed to be a waiver of any

Agreement be held invalid by reason of any law, statute or regulation existing

by a legally enforceable directive of any governmental body, such section or
portion thereof shall be validly reformed so as to approximate the intent of the
parties as nearly as possible and, if unreformable, shall be deemed divisible

otherwise be affected.
