ARTICLE 2 - GRANT OF RIGHTS

2.1 Exclusive License to Abbott.

    (A) VIVUS hereby grants to Abbott an exclusive license (exclusive even as to
        VIVUS) to use and sell the Product and any Improvements in the
        Territory, under the Licensed Patents, with right to sublicense, subject
        only to the rights of Astra AB under the Distribution Agreement between
        Astra AB and VIVUS dated May 29, 1996 ("Astra


                                  Page 4 of 55
<PAGE>   5


        Agreement"), the December 22, 1999 letter agreement from Astra AB to
        VIVUS regarding the termination of the Astra Agreement, and any other
        binding agreement or amendment between VIVUS and Astra relating to the
        Astra Agreement. Abbott may sublicense any one or more of its Affiliates
        at Abbott's sole discretion, and may sublicense third parties with
        VIVUS's prior written consent, such consent not to be unreasonably
        withheld. This exclusive license is granted to Abbott as to all uses,
        forms, indications, packages and strengths for the Product and any
        Product Improvements.

    (B) In the event that during the term of this Agreement, any country in the
        Janssen Territory as of the Effective Date ceases to be part of the
        Janssen Territory, and VIVUS has the right to grant the same license as
        to such country or countries as VIVUS has granted to Abbott pursuant to
        Article 2.1(A) above as to the Territory, then such country or countries
        (up to and including the entirety of the Janssen Territory, as the case
        may be) shall automatically become part of the Territory under this
        Agreement; provided that no such country shall become part of the
        Territory if, at the time such country becomes otherwise available,
        there are in effect export restrictions, economic sanctions, or other
        laws or regulations which prohibit United States corporations from
        selling goods to such country. The parties acknowledge and agree that
        neither party shall take any action in violation of VIVUS's contractual
        obligations to Janssen or otherwise in violation of applicable law, with
        respect to this Article 2.1(B).

2.2 Future Product Rights.

    (A) Subject to the provisions of this Article 2.2, VIVUS hereby grants to
        Abbott an exclusive right of first refusal to obtain an exclusive
        license (exclusive even as to VIVUS) in the Territory to use and sell
        Future Products, to the extent VIVUS has the right to grant such a
        license. Abbott shall have a separate and independent right of first
        refusal as to each Future Product pursuant to this Article 2.2. The
        parties acknowledge that VIVUS (or VIVUS INC, or its or their
        Affiliates, as the case may be) may license or acquire rights to a
        Future Product from a third party, and that VIVUS may not be permitted
        to license or sublicense such rights to Abbott for the full Territory or
        for all fields; but the parties agree that VIVUS and VIVUS INC. shall
        use their best efforts to obtain rights to any such Future Product from
        such third party on a



                                  Page 5 of 55
<PAGE>   6

        basis which will permit VIVUS to license or sublicense such rights to
        Abbott for the full Territory and for all fields. VIVUS shall not
        discuss, negotiate, entertain, solicit, offer, accept or enter into any
        agreement granting to a third party the right to use and sell such
        Future Product in the Territory except as expressly set forth in Article
        2.2(B) below.

    (B) During the term of this Agreement, VIVUS shall use diligent efforts to
        determine whether and when VIVUS wishes to pursue commercialization
        (directly or via a third party) of each of the Future Products in the
        Territory. In each case, but in no event earlier than September 15,
        2001, after VIVUS has completed its first Phase II study with a Future
        Product, VIVUS shall provide Abbott with the results of this Phase II
        study, the Investigational New Drug Application ("IND") (or the
        equivalent of an IND filed with any regulatory agency in the Territory)
        under which this Phase II study was conducted and the results of all
        completed clinical trials under this IND. Within ninety (90) days
        following receipt of such data, Abbott shall notify VIVUS of its
        decision whether or not it wishes to accept an exclusive license for
        such Future Product in the Territory. If Abbott does not wish to accept
        such license, then VIVUS shall be free to negotiate with third parties
        concerning the grant of rights to use and sell such Future Product on
        terms VIVUS deems appropriate, or pursue commercialization of such
        Future Product itself and shall have no further obligation under this
        Article 2.2 with respect to such Future Product.

    (C) If Abbott notifies VIVUS that it does wish to accept such license, then
        such Future Product shall become a Product under this Agreement as of
        the date of Abbott's notice of acceptance, and shall be subject to the
        terms and conditions of this Agreement with the exception of Articles 3
        (in its entirety), 4.3, 9.2 and Exhibit 4, provided that each Future
        Product which so becomes a Product under this Agreement shall also be
        subject to the provisions expressly set forth in Articles 2.2(D) and 8.6
        below, which provisions shall govern for each such Future Product in
        case of any conflict with other provisions of this Agreement. In no
        event shall the provisions of Articles 2.2(D) and 8.6 below apply to the
        MUSE Product or the ALIBRA Product or any Improvements thereof.

    (D) In the event that a Future Product becomes a Product under this
        Agreement pursuant to Article 2.2(B) and (C) above, then the following
        provisions shall apply:

               thirty (30) days of the date upon which the first patient is

               Product;

        (iii)  Abbott shall pay to VIVUS an amount equal to (***) of VIVUS's
               actual, verified out-of-pocket costs for the Phase III studies

               thirty (30) days after the end of each calendar quarter, as such
               costs are incurred subject to Article 8.6 below;

        (iv)   Abbott shall pay to VIVUS an amount equal to (***) of VIVUS's
               actual, verified out-of-pocket costs for the Phase II and III
               studies (in the case of Phase III studies, such costs are payable
               only if incurred subject to Article 8.6 below) relating to such
               Future Product (bringing the total such amounts paid by Abbott to
               (***) of such costs), payable within thirty (30) days of the date
               by which such Future Product has obtained Marketing Authorization

               be a Trademark under this Agreement, exclusively licensed to
               Abbott in the Territory for use in connection with such Future
               Product, and which shall be used where possible by VIVUS and/or
               its licensees in connection with such Future Product outside the
               Territory;

        (vi)   VIVUS shall sell such Future Product to Abbott pursuant to
               Article 4, provided that (i) Article 4.3 and Exhibit 4 shall not
               apply, and (ii) the price of such Future Product shall in no
               event be less than VIVUS's actual variable cost (includes direct
               labor and material and all overhead that is directly related to
               the manufacture of such Future Product and specifically




                                  Page 7 of 55

               Abbott in the Territory as samples shall be VIVUS's actual,
               variable cost (includes direct labor and material and all
               overhead that is directly related to the manufacture of such
               samples and specifically excludes fixed overhead items such as

               obtaining and maintaining all Regulatory Approvals for such
               Future Product in the Territory, provided that clinical
               development costs for such Future Product which are necessary to
               support the Marketing Authorization for such Future Product in
               the European Countries shall be shared by the parties as set

    (B) The parties shall conduct a reconciliation no later than forty-five (45)
        days after the end of each Sales Quarter, in order to determine whether
        one party owes the other party any amount in connection with the sale

        Quarter, based upon the difference (if any) between the respective
        Transfer Price and the Supply Price for that Sales Quarter. For the
        purposes of such reconciliation, Abbott shall provide to VIVUS a
        statement of Abbott's sales in units, per country in the Territory, and
        of Abbott's Net Sales, per country in the Territory and in local
        currency as well as in U.S. dollars, converted pursuant to Article 4.7

Abbott, then VIVUS will provide to Abbott all documents, including copies of
third-party invoices, evidencing such costs.

4.6        Records.

    (A) Abbott and/or its Affiliates shall keep and maintain records of sales
        made pursuant to the license granted hereunder so that Abbott's Net
        Sales and the calculation of the Transfer Price and the Supply Price may
        be verified. Such records shall be open to inspection upon prior written
        notice at any reasonable time during business hours, not more than once
        per calendar year, and each inspection shall cover no more than the two
        (2) calendar years preceding such notice of inspection. The inspection
        shall be conducted at VIVUS's expense by a nationally recognized
        independent certified public accountant who is not VIVUS's auditor of
        record and who is selected by VIVUS and approved by Abbott, which
        approval shall not be unreasonably withheld. The accountant shall be
        bound by confidentiality obligations at least as stringent as those
        provided in Article 19 of this Agreement, and shall then have the right
        to examine the records kept pursuant to this Agreement and report to
        VIVUS the findings (but not the underlying data) of the inspection as
        are necessary to evidence that the records were or were not maintained
        and used in accordance with this Agreement. A copy of any report
        provided to VIVUS by the accountant shall be given concurrently to
        Abbott. If the inspection of records reveals more than five percent (5%)
        underpayment by Abbott for the purchase of the Products (calculated as a
        percentage of all such payments made in connection with a Sales Year),
        then the expenses for the accountant shall be borne by Abbott and Abbott
        shall promptly repay to VIVUS the amount of such underpayment, plus
        interest calculated at the prime rate of interest as published in the
        Wall Street Journal for the date upon which such underpayment was made.
        For the purposes of this Article 4.6, an "underpayment" shall not
        include any amount that the parties determine is owed to VIVUS pursuant
        to the reconciliation procedure set forth in Article 4.2(B) above.

    (B) VIVUS and VIVUS INC. and/or its or their Affiliates shall keep and
        maintain records of their costs of clinical development, regulatory work
        and samples relating to any Future Product which becomes a Product under
        this Agreement pursuant to Article 2.2 above, so that Abbott may verify
        such costs to the extent that Abbott is obligated under this Agreement
        to make payments to VIVUS based on such costs. Such records shall




                                 Page 11 of 55
<PAGE>   12

        be open to inspection upon prior written notice at any reasonable time
        during business hours, not more than once per calendar year, and each
        inspection shall cover no more than the two (2) calendar years preceding
        such notice of inspection. The inspection shall be conducted at Abbott's
        expense by a nationally recognized independent certified public
        accountant who is not Abbott's auditor of record and who is selected by
        Abbott and approved by VIVUS, which approval shall not be unreasonably
        withheld. The accountant shall be bound by confidentiality obligations
        at least as stringent as those provided in Article 19 of this Agreement,
        and shall then have the right to examine the records kept pursuant to
        this Agreement and report to Abbott the findings (but not the underlying
        data) of the inspection as are necessary to evidence that the records
        were or were not maintained and used in accordance with this Agreement.
        A copy of any report provided to Abbott by the accountant shall be given
        concurrently to VIVUS. If the inspection of records reveals more than
        five percent (5%) overpayment by Abbott for payments made based on such
        costs (calculated as a percentage of all such payments made), then the
        expenses for the accountant shall be borne by VIVUS and VIVUS shall
        promptly repay to Abbott the amount of such overpayment, plus interest
        calculated at the prime rate of interest as published in the Wall Street
        Journal for the date upon which such overpayment was made. For the
        purposes of this Article 4.6, an "overpayment" shall not include any
        amount that the parties determine is owed to Abbott pursuant to the
        reconciliation procedure set forth in Article 4.2(B) above.

4.7 Payments. Any payments due VIVUS or Abbott under this Agreement shall be
made by remitting to the bank account designated by the party to whom payment is
to be made. Any such payments shall be made in U.S. Dollars and, in the case of
quarterly payments based upon Abbott Net Sales in currencies other than U.S.
Dollars, such quarterly payments shall be the sum of payments due for the three
(3) months of the applicable quarter calculated for each such month using the
beginning and ending month's published exchange rate, set one business day prior
to month end, by Reuters divided by two (if a Reuters exchange rate is not
available for certain countries, an exchange rate established by a recognized
third party will be used). Any payment which is more than ten (10) days overdue
shall bear interest from the original due date at the prime rate of interest as
published in the Wall Street Journal for the due date.




                                 Page 12 of 55
<PAGE>   13

4.8 Taxes. Where any sum due to be paid to VIVUS hereunder is subject to any
withholding or similar tax, the parties shall use their best efforts to do all
such acts and things and to sign all such documents as will enable them to take
advantage of any applicable double taxation agreement or treaty. In the event
there is no applicable double taxation agreement or treaty, or if an applicable
double taxation agreement or treaty reduces but does not eliminate such
withholding or similar tax, Abbott shall pay such withholding or similar tax to
the appropriate government authority, deduct the amount paid from the amount due
VIVUS and secure and send to VIVUS the best available evidence of such payment.

ARTICLE 5 - FORECASTS, ORDERS, INVOICES AND TITLE

5.1 Initial Forecast. Within sixty (60) days of the Effective Date, Abbott shall
give VIVUS its then current best forecast of the quantity of Products that
Abbott will require from VIVUS prior to and during the first four Sales
Quarters. Abbott shall break down the forecast for the period prior to the first
Sales Quarter and for the first two Sales Quarters of such forecast by month and
by Stock Keeping Unit ("SKU") per Product.

5.2 Rolling Forecasts. No later than seventy-five (75) days prior to the first
day of each Sales Quarter after the initial Sales Quarter, Abbott shall give
VIVUS its then current best forecast of the quantity of Products that Abbott
will require from VIVUS during each of the next four (4) Sales Quarters. Abbott
shall break down the forecast for the first two such Sales Quarters of the
forecast by month and by SKU per Product.

5.3 Order and Acceptance. The forecast for the first Sales Quarter in each of
Abbott's rolling forecasts made pursuant to Article 5.2 above shall constitute
Abbott's firm order for that Sales Quarter, and all firm orders shall specify
delivery date(s) no less than ninety (90) days from the date of such firm order.
Abbott shall not increase or decrease its forecast (by SKU and in total), for
the second Sales Quarter in each of Abbott's rolling forecasts made pursuant to
Article 5.2 above, by more than twenty percent (20%). VIVUS shall accept all
firm orders from Abbott for quantities of Products up to and including one
hundred twenty percent (120%) of the quantity (by SKU and in total) of Products
previously forecasted by Abbott for such Sales Quarter, and shall use its best
efforts to accept all firm orders from Abbott for quantities of Products in
excess of that quantity of Products. Abbott shall not increase or decrease its
forecast, for the third Sales Quarter in each of Abbott's rolling forecasts made
pursuant to Article 5.2 above, by more than fifty percent (50%). VIVUS shall
accept all firm orders from Abbott for quantities of Products




                                 Page 13 of 55
<PAGE>   14


up to and including one hundred fifty percent (150%) of the quantity of Products
previously forecasted by Abbott for such Sales Quarter, and shall use its best
efforts to accept all firm orders from Abbott for quantities of Products in
excess of that quantity of Products. Once an order has been accepted by VIVUS,
then VIVUS shall be obligated to sell, and Abbott shall be obligated to
purchase, the ordered Products.

5.4 Invoices. VIVUS shall invoice Abbott for the Transfer Price in United States
dollars for the Products shipped. Abbott shall pay VIVUS such invoiced amount
within thirty (30) days from the date of the invoice.

5.5 Delivery. VIVUS shall deliver the Products to Abbott, FOB at VIVUS's
facilities located in Lakewood, New Jersey, USA. All shipping costs, liability,
ownership and logistics of Product beyond the Lakewood facility's loading dock
are the responsibility of Abbott.

5.6 Conflicting Terms and Conditions. Except as otherwise provided in this
Agreement, the terms and conditions of this Agreement shall govern,
notwithstanding any additional or inconsistent terms or conditions in Abbott's
form of purchase order or similar document or in VIVUS's acknowledgment,
invoice, or similar documents.

5.7 Post-Expiration Supply. In the event that this Agreement expires pursuant to
Article 17.1 below, and Abbott wishes to continue purchasing the Products from
VIVUS, the parties shall promptly negotiate in good faith the terms and
conditions of a supply agreement for the Products. The Supply Price shall not be
applicable to the sale and purchase of the Products under such separate supply
agreement.

ARTICLE 6 - SAMPLING, TESTING AND ANALYSIS

6.1 Certificate of Analysis. VIVUS shall test or cause to be tested each lot of
the Products pursuant to the Specifications before delivery to Abbott. Each test
shall set forth the items tested, specifications and test results in a
certificate of analysis for each lot delivered. VIVUS shall send or cause to be
sent such certificates to Abbott along with delivery of the Products. Abbott is
entitled to rely on such certificates for all purposes of this Agreement. Abbott
will perform any testing upon entry of the Products into the European Union, or
elsewhere in the Territory, that is necessary for the sale or distribution of
such Product in the territory.

6.2 Manufacturing Compliance.

    (A) On each certificate of analysis provided to Abbott pursuant to Article
        6.1 above, VIVUS shall provide or cause to be provided for each lot of
        the Products purchased a




                                 Page 14 of 55
<PAGE>   15

        statement which will certify that the lot of Products was manufactured
        in accordance with the Specifications and applicable current Good
        Manufacturing Practices ("cGMP") laws and/or regulations.

    (B) Notwithstanding VIVUS's obligation to provide such statement, within
        ninety (90) days of the Effective Date, VIVUS shall permit Abbott to
        inspect, or obtain permission for such inspection, during reasonable
        business hours and upon reasonable prior notice to VIVUS, those areas of
        the facilities where the Products are manufactured, stored, tested and
        handled and to manufacturing records of the Products manufactured by
        VIVUS and/or VIVUS's third-party contract manufacturer(s).

    (C) VIVUS shall advise Abbott promptly if an authorized agent of any
        governmental body in the Territory inspects any of the facilities
        concerning the Products. VIVUS shall promptly furnish to Abbott a copy
        of all material documents and/or written communications relating to such
        visit and the application of such visit to the Products, if any.

    (D) If any such governmental body inspection and/or document or
        communication described in Article 6.2(C) above gives rise to any
        changes in VIVUS's or VIVUS's third-party contract manufacturer(s)
        facilities or manufacturing processes, technical documentation or
        record-keeping relating to the Products (or in the facilities, processes
        or record-keeping of VIVUS's third-party contract manufacturer(s)),
        VIVUS shall advise Abbott of such changes no later than ninety (90) days
        prior to the date upon which such changes become effective; provided
        that, if VIVUS does not itself receive at least ninety (90) days prior
        notice of any such change, then VIVUS shall notify Abbott of such change
        promptly after receiving its own notice.

    (E) If VIVUS or VIVUS's third-party contract manufacturer(s) for any reason,
        other than under Article 6.2(D) above, makes any changes in its or their
        facilities or manufacturing processes, technical documentation or
        record-keeping relating to the Products, VIVUS shall advise Abbott of
        such changes no later than ninety (90) days prior to the date upon which
        such changes are to become effective. Such changes shall be deemed
        accepted by Abbott unless Abbott notifies VIVUS to the contrary within
        such ninety (90) day or other agreed period. If Abbott notifies VIVUS
        that Abbott does not accept such changes, then the parties shall
        promptly meet and mutually determine in good faith any modifications to
        such changes that should be made in




                                 Page 15 of 55
<PAGE>   16

        order to render such changes acceptable to Abbott. The parties
        acknowledge and agree that in considering or implementing any changes or
        modifications to changes being considered and/or made under this Article
        6.2, the parties shall act in such a manner as to avoid, as far as
        possible, any delay or interruption in the supply of Products to Abbott
        and in Abbott's ability to market and sell the Products in the
        Territory.

    (F) The parties acknowledge that the specific requirements, including time
        period, of Section 6.2 (D) and Section 6.2(E) above, may be modified in
        writing by the separate technical agreement referred to in Section 6.6
        below.

6.3 Defective Product. Abbott shall notify VIVUS in writing of any claim
relating to damaged, defective or nonconforming Products or any shortage in
quantity of any shipment of the Products within thirty (30) days of receipt of
such Products. If Abbott fails to give such written claim notice to VIVUS within
said thirty (30) day period, the Products shipped shall be deemed to be
conforming, not damaged nor defective at the time of delivery and shall be
deemed to be sufficient in quantity. If Abbott gives such written claim notice
to VIVUS within said thirty (30) day period, then Abbott and VIVUS shall, in an
appropriate manner to be agreed, jointly inspect the Products to see if claimed
nonconformity, damage or defect actually exists in the Products shipped. If
existence of claimed nonconformity, damage, defect or shortage is reasonably
verified through such inspection, VIVUS shall replace the rejected Products or
make up the shortage as soon as practicable but no later than ninety (90) days
after such verification, at no extra cost to Abbott, and shall make arrangements
with Abbott for the destruction of any rejected Products, at VIVUS's expense.

6.4 Discrepant Inspection Results. In the event of a discrepancy between
Abbott's and VIVUS's inspection results such that one party's results fall
within the Specifications and the other party's results fall outside the
Specifications, the parties shall cause an independent tester, mutually
acceptable to the parties, to perform comparative tests on samples of the
allegedly defective Products. The independent tester's results shall be final
and binding and the parties shall share equally in the cost of the independent
tester.

6.5 Specifications. The Specifications may be modified from time to time by
written agreement of the parties without the necessity of amending this
Agreement.

6.6 Technical Agreement. Within sixty (60) days, the respective manufacturing
groups of VIVUS and Abbott shall enter into a separate technical agreement, in a
format suitable for




                                 Page 16 of 55
<PAGE>   17

submission to the regulatory authorities in each country in the Territory,
recording the Specifications and Manufacturing Standards and measures to ensure
compliance with applicable regulations relating to production, storage,
transportation and release of the Products. Such Technical Agreement will also
further define, as appropriate, the specific requirements and timing for Section
6.2 (D) and Section 6.2 (E), above.


ARTICLE 7 - PATENTS

7.1 Patent Prosecution and Maintenance. To the extent it has the right to do so,
VIVUS shall, at its sole cost and expense, maintain any patent applications and
patents listed in Exhibit 1.8 and/or included in Licensed Patents, and shall
diligently prosecute any such patent applications and obtain all available
patent term extensions; provided that VIVUS may decide, subject to Abbott's
prior written consent (which consent shall not be unreasonably withheld or
delayed), not to prosecute certain of the Licensed Patents, or to cause or
permit certain of the Licensed Patents to lapse or become abandoned in the
Territory if, in VIVUS's reasonable commercial judgment, such decision would not
adversely affect Abbott's ability to exercise its rights and perform its
obligations under this Agreement. To the extent it does not have the right to
maintain such patent applications and patents, prosecute such patent
applications and obtain patent term extensions, VIVUS shall use its best efforts
to ensure that the third party who has the right to take such actions shall do
so. VIVUS shall keep Abbott informed on a quarterly basis and also on Abbott's
reasonable written request about the status of such patent applications and/or
patents, including but not limited to providing Abbott with copies of all
material documents relating to the prosecution and/or the maintenance of the
Licensed Patents in a timely manner so as to allow Abbott a reasonable
opportunity to review and comment on VIVUS's planned patent strategy.

ARTICLE 8 - DEVELOPMENT AND REGULATORY ISSUES

8.1 VIVUS Responsibilities. VIVUS shall be responsible for, and shall bear all
costs of, the following:

    (A) VIVUS shall be responsible for obtaining all Marketing Authorizations
        for the Products in Abbott's name in those countries in Europe which are
        listed on Exhibit 8.1 attached to this Agreement, including but not
        limited to conducting any clinical studies with the Products which may
        be necessary to obtain Marketing Authorization




                                 Page 17 of 55
<PAGE>   18

        for the Products, with labeling for the MUSE Product equivalent to the
        labeling in effect for the MUSE Product as of the Effective Date, and
        with labeling for the ALIBRA Product which the parties mutually
        negotiate with the applicable governmental authorities, and for
        maintaining such Marketing Authorizations until such Marketing
        Authorizations are transferred to Abbott. Promptly after the Effective
        Date, VIVUS shall transfer to Abbott all Marketing Authorizations in the
        Territory for the MUSE Product, and all Marketing Authorization
        applications in the Territory for the ALIBRA Product, as expeditiously
        as possible.

    (B) VIVUS shall provide to Abbott, as expeditiously as possible, any and all
        authorizations, assistance, information and/or materials in VIVUS's
        possession or control required by Abbott in order to enable Abbott to
        market and sell the Products in the Territory (including, but not
        limited to authorizations, assistance, information and/or materials
        relating to Regulatory Approval of the Products by the United States
        Food and Drug Administration and by the European Medicines Evaluation
        Agency, and to the Drug Master Files for the Products). To the extent
        that any material, information, data or documents required by Abbott are
        not in VIVUS's possession or control, VIVUS shall use reasonable efforts
        to obtain such material, information, data or documents for Abbott.

    (C) In fulfilling its obligations under this Agreement, VIVUS shall use its
        best efforts to ensure that the Products are entitled to and receive the
        maximum benefit of any regulatory market exclusivity periods or other
        safeguards or extensions of proprietary status, which are or may be
        applicable in the Territory.

    (D) VIVUS shall be responsible for filing trademark applications for, and
        for the maintenance and upkeep of, the Trademarks in the Territory.

    (A) Abbott shall be responsible for (i) maintaining all Marketing
        Authorizations obtained by VIVUS for the Products in the countries
        listed on Exhibit 8.1, once such Marketing Authorizations have been
        transferred to Abbott; (ii) obtaining all pricing and reimbursement
        approvals in Abbott's name for the Product in the countries listed on
        Exhibit 8.1; and (iii) obtaining and maintaining all Regulatory

                                 Page 18 of 55
<PAGE>   19

        which may be necessary to obtain Marketing Authorization for the
        Products, for the countries in the Territory outside of the countries
        listed on Exhibit 8.1. Should Abbott in connection with the Products
        conduct clinical studies, the parties endeavor to work by consensus in
        the development of protocols for such clinical studies.

    (B) Abbott shall own all registrations and Regulatory Approvals for the
        Products in the Territory.

    (C) In fulfilling its obligations under this Agreement, Abbott shall use its
        best efforts to ensure that the Products are entitled to and receive the
        maximum benefit of any regulatory market exclusivity periods or other
        safeguards or extensions of proprietary status, which are or may be
        applicable in the Territory.

8.3 Pharmacovigilance. Promptly after the Effective Date, the respective
pharmacovigilance groups of VIVUS and Abbott shall enter into a separate
agreement covering adverse event information exchange relating to the Products.
Such agreement will permit the inclusion of the respective pharmacovigilance
groups of other third parties to whom VIVUS has granted or will grant (during
the term of this Agreement) a license under the VIVUS Technology to make, have
made, use and sell the Products in the United States or in the Janssen
Territory.

8.4 Regulatory Communications. Abbott and VIVUS shall promptly inform each other
of any material communications to or from governmental authorities or agencies
relating to the Products, including but not limited to providing each other
promptly with copies of any material written communications. With the exception
of product recalls, which are to be handled pursuant to Article 10 below, or
visits by governmental body to any of the facilities where the Products are
manufactured, which are to be handled pursuant to Article 6.2 above, and of
adverse event reporting, which is to be handled pursuant to Article 8.3 above,
the parties shall consult with each other regarding any issues raised in such
communications, and shall attempt in good faith to agree upon any action to be
taken or response to be made in connection with such communications. If the
parties are unable to agree within a reasonable time prior to when the action is
to be taken or the response is to be made the party responsible for obtaining
Marketing Authorization for the Product in the country in question shall decide
what action to take or response to make.

8.5 Improvements. In the event that development and/or regulatory work and/or
costs are required in order to commercialize an Improvement, the parties shall
negotiate in good faith to




                                 Page 19 of 55
<PAGE>   20

determine the development and/or regulatory strategy and work, and how to
allocate the costs therefor.

8.6 Future Product Development Committee. For each Future Product that becomes a
Product pursuant to Article 2.2 above, Abbott and VIVUS shall form a Development
Committee which shall be responsible for creating and implementing the clinical
development plan for such Future Product from Phase III forward, and for
creating and implementing the regulatory strategy for obtaining Marketing
Authorization for such Future Product in the European Countries set forth on
Exhibit 8.1 attached hereto, including the creation and management of the budget
for such clinical development of and regulatory strategy for such Future
Product. The Development Committee shall be organized and operated as set forth
in this Article 8.6.

    (A) The Development Committee shall consist of no more than six (6)
        individuals, an equal number of which shall be representatives,
        respectively, from Abbott and VIVUS, and shall be chaired alternatively
        on an annual basis by one (1) of the VIVUS representatives and by one
        (1) of the Abbott representatives. Each party's representatives on the
        Development Committee shall be an employee of such party and each shall
        have one (1) vote on any matter arising for decision by the Development
        Committee. Each party shall have the right, at any time, to designate by
        written notice to the other party, a replacement, on a permanent or
        temporary basis, for any of such party's members on the Development
        Committee.

    (B) The Development Committee shall endeavor to work by consensus. In the
        event of a deadlock in any vote on any issue to be decided by the
        Development Committee, the parties shall refer the deadlocked issue to
        VIVUS's Vice President of Research and Development and Abbott's
        International Division Vice President of Medical Affairs. These
        individuals shall attempt, promptly and in good faith, to resolve such
        issue amicably. If such issue remains deadlocked, the parties shall
        refer such issue to, respectively, the President of VIVUS, and the
        President of Abbott's International Division. Any issue remaining
        deadlocked after this last step shall be resolved through an Alternative
        Dispute Resolution ("ADR") procedure pursuant to Article 20.11 below.




                                 Page 20 of 55
<PAGE>   21

    (C) The Development Committee shall meet as necessary, in person or
        otherwise, as the parties shall agree, but no less than once per
        calendar quarter. The chairperson shall be responsible for scheduling
        and arranging such meetings and ensuring that all of the members or
        their designated replacements are able to attend. Each party shall bear
        its own costs, including travel costs, for its representatives on the
        Development Committee attending any meeting of the Development
        Committee.

    (D) Within sixty (60) days of a Future Product becoming a Product under this
        Agreement in accordance with Article 2.2 above, the parties shall reach
        written agreement, through the Development Committee, on the plan for
        the clinical development and regulatory work relating to such Future
        Product for the remainder of that calendar year ("Initial Period") and,
        separately, for the budget therefor. It is understood and agreed that
        any clinical development or regulatory work that had already begun by
        VIVUS at the time a Future Product becomes a Product under this
        Agreement in accordance with Article 2.2 above, will automatically
        become a part of the written agreement on the plan for the clinical
        development and regulatory work related to such Future Product including
        the budget therefor and will not require the approval of the Development
        Committee as long as this plan and a reasonable estimate of costs was
        provided to Abbott during the ninety (90) day evaluation period
        described in Article 2.2 (B) above. Following the Initial Period, at
        least ninety (90) days prior to January 1 of each year, the Development
        Committee will update such plan and budget therefor for the next
        calendar year. Each such plan and budget must be approved by the
        Development Committee, and by VIVUS's President and Abbott's
        International Division Vice President of Medical Affairs, such approval
        not to be unreasonably withheld, before the Development Committee may
        implement such plan and budget. Notwithstanding any other provision in
        this Agreement to the contrary, Abbott shall not be obligated to make
        any payments with respect to any clinical development work done in
        connection with any Future Product unless such work, and the budget
        therefor, was approved in accordance with this Article 8.6(D).

    (E) All applications for Regulatory Approval for such Future Product in the
        Territory shall




                                 Page 21 of 55

        be made in Abbott's name and all Regulatory Approvals obtained in the
        Territory for such Future Product shall be owned by Abbott.

    (F) VIVUS shall bear the costs of all clinical development of such Future
        Product that are necessary to support the Marketing Authorization for
        such Future Product in the European Countries, except as provided
        otherwise expressly in Article 2.2(D) above.

    (G) Abbott shall bear the costs of, and make all final decisions with
        respect to, the regulatory strategy for all aspects of obtaining
        Regulatory Approval in the Territory.

    (H) At the written request of VIVUS, the Development Committee for a given
        Future Product shall be expanded to include VIVUS's other licensee(s),
        if any, for such Future Product outside the Territory that become a
        licensee after the Effective Date of this Agreement, for the sole
        purpose of making the clinical development of such Future Product as
        efficient as possible on a worldwide basis. Abbott and VIVUS intend that
        the Development Committee's discussions and activities shall comply at
        all times with applicable laws and regulations, including but not
        limited to applicable antitrust and/or competition law, and no
        commercial information shall be shared, or discussion of commercial
        issues shall be permitted. Each such additional VIVUS licensee shall
        have an equal number of members on the Development Committee as do VIVUS
        and Abbott respectively, and VIVUS shall ensure that each such
        additional VIVUS licensee complies with the Development Committee
        procedures as set forth in this Article 8.6. Abbott shall not be
        required, and VIVUS shall not be permitted, to share any clinical or
        other data generated by Abbott with such additional licensee(s) without
        Abbott's prior written consent and such consent will not be unreasonably
        withheld. Abbott shall not be required to pay any portion of the costs
        of any clinical studies or other clinical development that relate to any
        country or area outside the Territory, except as provided otherwise
        expressly in Article 2.2(D) above.

ARTICLE 9 - MARKETING AND SALES

9.1 Abbott Diligence. In addition to the items set forth in Article 3.1 above,

commercialization of Abbott's own products of similar market




                                 Page 22 of 55

potential, including but not limited to products for the treatment of erectile
dysfunction, taking into consideration the proprietary or non-proprietary status
of the Products and determining, in Abbott's best commercial judgment, whether
and how to launch the Products in a given country of the Territory, and what if
any promotional tools are reasonably necessary or desirable in marketing and/or
selling the Products in the Territory. Abbott shall make any such launches and
utilize any such promotional tools at Abbott's own expense.

9.2 Missed Targets. In the event that the fee provided in Article 3.1(B) above
does not become payable by the end of the third Sales Year, or that the fee
provided in Article 3.1(C) above does not become payable by the end of the sixth
Sales Year, then VIVUS may terminate this Agreement upon thirty (30) days
written notice; provided that in either event, if Abbott's annual Net Sales are
at least (i) sixty percent (60%) of the amount specified in Article 3.1(B) or
(C) (as the case may be) in the European Countries listed in Exhibit 8.1 or (ii)
seventy-five percent (75%) of the amount specified in Article 3.1(B) or (C) (as
the case may be) in the Territory, as of the date of VIVUS's notice of
termination, then Abbott may, at its option, avoid termination by paying to
VIVUS an amount equal to the fee otherwise applicable under Article 3.1(B) or
(C) (as the case may be). If Abbott makes such payment within thirty (30) days
of the date of VIVUS's notice of termination, then such notice shall become null
and void, and this Agreement shall remain in full force and effect.

government authority issues a request, directive or order that a Product be
recalled, or (ii) a court of competent jurisdiction orders such a recall, or
(iii) Abbott and VIVUS jointly determine that a Product should be recalled,
Abbott shall take all appropriate corrective actions. If such recall results
from any cause or event attributable solely to VIVUS's negligence or fault,
VIVUS shall be responsible for the direct expenses of the recall. If such recall
results from any cause or event attributable solely to Abbott's negligence or
fault, Abbott shall be responsible for the direct expenses of the recall. If
such recall results from any other cause or event (including attribution to the
negligence or fault of both VIVUS and Abbott), the parties shall share equally
the direct expenses of the recall. For the purposes of this Agreement, the
direct expenses of recall shall include, without limitation, the expenses of
notification and return of the recalled Products and

any government authority issues a request, directive or order that a Product be
recalled, or (ii) a court of competent jurisdiction orders such a recall, or
(iii) VIVUS (or its Affiliates or sublicensees, as the case may be) decides that
the Products should be recalled, VIVUS shall notify Abbott no later than five
(5) business days prior to the effective date of such recall, and shall provide
Abbott with all information and assistance as Abbott may reasonably request in
order to enable Abbott to determine any appropriate actions relating to the
Products in the Territory arising from such recall.

ARTICLE 14 - ALLOCATION OF SUPPLY




                                 Page 28 of 55
<PAGE>   29

14.1 Allocation of Supply. In the event of VIVUS's inability for any reason to
supply the Products ordered by Abbott, VIVUS shall allocate its available supply
between Abbott, VIVUS and VIVUS's licensee(s) outside the Territory on a fair
and equitable basis based on a pro-rata share of worldwide Product sales for the
six (6) months preceding and the forecasted worldwide Product sales for the next
six (6) months following such allocation. If VIVUS is unable to supply ninety
percent (90%) of the Products (on a Product-by-Product basis) ordered by Abbott
and accepted by VIVUS pursuant to Articles 5.3, 5.5 and 5.6 of this Agreement
for a total of four (4) Months, whether or not consecutive, in any consecutive
twelve (12) Month period, Abbott may at its sole option: (i) forgo the
quantities ordered that VIVUS is unable to supply; (ii) take delivery within a
reasonable period of time after VIVUS becomes able to supply the quantities
ordered; or (iii) make or have a third party make, or permit VIVUS to have a
third party (approved by Abbott) make, the Product that VIVUS fails to supply.

14.2 Quality Assurance. In the event that an inspection or report by an
authorized agent of a governmental agency in the Territory reveals that VIVUS's
(or VIVUS's third-party contractor's) facilities and processes for manufacturing
the Products do not comply with applicable laws and regulations, including
without limitation Good Manufacturing Practices, and such lack of compliance
results in VIVUS's inability to fulfill its obligations to Abbott under this
Agreement, then Abbott may, at its sole option, make or have a third party make,
or permit VIVUS to have a third party (approved by Abbott) make, the Products
that VIVUS is not able to supply.

14.3 Right to Manufacture Product. In the event Abbott selects option 14.1(iii)
and/or option 14.2 above, then Abbott shall have the right to make and/or have a
third party make Product and such right shall continue in effect until such time
as VIVUS provides Abbott not less than six (6) months notice and demonstrates
that it is able to adequately supply Abbott's reasonable requirements of Product
in the Territory and VIVUS shall transfer to Abbott or to Abbott's or VIVUS's
designated third party manufacturer all information, assistance, materials and
authorizations useful and necessary with respect to the manufacture, storage and
shipment of the Products, in a timely manner so as to avoid any delay or
interruption in supply of the Products to Abbott. VIVUS shall reimburse Abbott
for up to (***) of Abbott's actual, verified out-of-pocket start-up costs
incurred by Abbott to manufacture Product under this Article 14.3. Abbott shall
pay to VIVUS a royalty on the Net Sales of such Products that are manufactured
under this Article 14.3 equal to the greater of (i) the Supply Price pursuant to
Article 4.2 above less




                                 Page 29 of 55
<PAGE>   30

Abbott's actual cost of obtaining such Product from a third party or its
variable cost (includes direct labor and material and all overhead that is
directly related to the manufacture of such Product and specifically excludes
fixed overhead items such as facilities rent, depreciation, common utilities,
taxes and insurance, etc.) to manufacture such Product and, (ii) (***) of Net
Sales of such Product.

ARTICLE 15 - TRADEMARKS

15.1 Trademark Rights. VIVUS hereby grants to Abbott the exclusive right,
exclusive even as to VIVUS, to use the Trademarks in connection with the
Products in the Territory during the term of this Agreement. Abbott acknowledges
that such Trademarks shall be and are the sole property of VIVUS. In the event
that VIVUS decides to divest itself of the Trademarks, VIVUS shall assign such
Trademarks in the Territory to Abbott upon Abbott's written request.

15.2 Electronic Address. VIVUS hereby grants to Abbott a non-exclusive right to
use VIVUS's registered electronic address, www.vivus.com, for the purpose of
linking electronic users with Abbott's relevant web pages, web sites or other
electronic addresses relating to the Product in the Territory.

15.3 Abbott's Own Mark. In the event that Abbott is unable to use the Trademarks
in connection with the Products in the Territory, for legal, regulatory or
cultural reasons, Abbott may elect to use trademarks of its own choosing in
connection with the Products in the Territory, after consultation with VIVUS,
instead of the Trademarks. VIVUS acknowledges that such trademarks shall be and
are the sole property of Abbott, and that the cost of adoption and registration
of such trademarks shall be borne by Abbott.

ARTICLE 16 - INFRINGEMENT

16.1 Third Party Infringement. Each party will notify the other party if it
becomes aware of the activities of any third party, which are believed to
infringe any of the Licensed Patents or the Trademarks. The parties shall
consult as to potential strategies against the alleged infringer, including but
not limited to litigation strategy.

16.2 Litigation.

    (A) If the efforts of the parties are not successful in abating the alleged
        infringement, then VIVUS shall have the right, but not the obligation,
        to bring an appropriate suit or action against such infringement, at its
        own expense. Abbott agrees to cooperate




                                 Page 30 of 55
<PAGE>   31

        in any such infringement action and agrees to execute all papers and
        perform such other acts as may be reasonably requested by Abbott, at
        VIVUS's expense. VIVUS shall consult with Abbott and take into account
        Abbott's recommendations regarding the conduct of such action, provided
        that VIVUS shall have full right and authority to determine the strategy
        and tactics for such action and to settle, consent to judgment, or
        otherwise resolve any such action or suit. The provisions of the
        foregoing notwithstanding, no such resolution shall be binding on Abbott
        without its prior written consent (which consent shall not be
        unreasonably withheld) unless such resolution does not (i) impose any
        liability, loss, cost or obligation upon Abbott and (ii) adversely
        affect Abbott's rights under this Agreement.

    (B) If VIVUS does not elect to bring suit against the alleged infringer,
        Abbott shall have the right, but not the obligation, to bring an
        appropriate suit or action against such infringer in the Territory, at
        Abbott's own expense. VIVUS agrees to cooperate in any such infringement
        action and agrees to execute all papers and perform such other acts as
        may be reasonably requested by Abbott (including but not limited to
        consent to be joined as a nominal party plaintiff in such action), at
        Abbott's expense. Abbott shall consult with VIVUS and take into account
        VIVUS's recommendations regarding the conduct of such action, provided
        that Abbott shall have full right and authority to determine the
        strategy and tactics for such action and to settle, consent to judgment,
        or otherwise resolve any such action or suit. The provisions of the
        foregoing notwithstanding, no such resolution shall be binding on VIVUS
        without its prior written consent (which consent shall not be
        unreasonably withheld) unless such resolution does not (i) impose any
        liability, loss, cost or obligation upon VIVUS and (ii) adversely affect
        VIVUS's rights under this Agreement.

    (C) If VIVUS or Abbott brings an infringement action pursuant to this
        Article 16, any amount recovered in any action or suit against a third
        party infringer shall be allocated as follows: first, to the party
        bringing such action in order to reimburse such party for the costs and
        expenses of such action; second, with respect to any remaining amount,
        sixty percent (60%) of that portion of such amount resulting from
        infringement within the Territory to Abbott, and the rest of any
        remaining amount to VIVUS.




                                 Page 31 of 55
<PAGE>   32

16.3 Alleged Infringement of Third Party Intellectual Property.

    (A) VIVUS shall indemnify and hold Abbott harmless against any judgment,
        damage, loss, cost or other expense (including legal fees) resulting
        from any claim or suit alleging infringement of any patent or trademark
        owned by a third party arising from Abbott's or its Affiliates' or
        sublicensees' use or sale of the Products and/ or any Improvements and/
        or use of any of the Trademarks in the Territory. Abbott shall promptly
        give notice to VIVUS of any such claim or suit, and VIVUS shall have
        full control over the defense of such claim or suit; provided that
        Abbott shall have the right to participate, at its own expense, with
        counsel of its own choosing, in such defense. Abbott shall provide to
        VIVUS such reasonable assistance at VIVUS's expense as VIVUS may, from
        time to time, reasonably request. VIVUS, at its option and expense, may
        dispose of such claim or may conduct the defense of such suit. If Abbott
        becomes obligated to make any payment, including but not limited to
        royalties and/ or damages, to any third party for patent, trademark or
        other intellectual property infringement allegedly attributable to the
        Products, in order to use and sell the Products in the Territory, such
        payments shall be creditable against Abbott's purchases of the Products,
        which would otherwise be payable to VIVUS hereunder. Abbott shall use
        its best efforts to minimize its third-party payment obligations under
        this circumstance. VIVUS shall not dispose of any such claim or suit by
        agreement, in any fashion which causes Abbott to be enjoined or
        otherwise prohibited from using or selling the Products in any country
        or countries of the Territory, without Abbott's prior written consent.

    (B) If Abbott is enjoined or otherwise prohibited from using or selling the
        Products in a given country in the Territory as a result of alleged
        patent or trademark infringement, then Abbott may exclude such country
        from the Territory upon written notice within thirty (30) days of the
        date of such final, permanent, unappealable or unappealed injunction or
        other order. If Abbott is enjoined or otherwise prohibited from making,
        having made, using or selling any of the Products and/or any of the
        Improvements and/or from using any of the Trademarks in all or a
        significant portion of the Territory as a result of alleged patent or
        trademark infringement, then, at Abbott's sole discretion, Abbott may
        exclude such portion of the Territory from this Agreement, or terminate
        this Agreement upon




                                 Page 32 of 55
<PAGE>   33

        written notice within thirty (30) days of the date of such final,
        permanent, unappealable or unappealed injunction or other order.

ARTICLE 17 - TERM AND TERMINATION

17.1 Term. The term of this Agreement shall commence on the Effective Date and
shall, unless earlier terminated pursuant to this Article 17 or other express
termination provisions in this Agreement, expire on a country-by-country and
Product-by-Product basis upon the later to occur of (i) the expiration of the
last Valid Claim that would be infringed by the manufacture, sale or use of the
Product in such country, and (ii) the tenth (10th) anniversary of the First
Commercial Sale of such Product. Upon the expiration of this Agreement and upon
Abbott's request the parties shall negotiate transfer of all rights to the
Trademarks in the Territory to Abbott.

17.2 Breach. Either party may, in addition to any other remedies available to it
by law or in equity, terminate this Agreement upon sixty (60) days' written
notice in the event that the other party commits a material breaches of this
Agreement and fails to cure such breach within sixty (60) days of notice of the
breach. The party giving notice of breach may withhold any payments otherwise
due and owing to the breaching party, to be used as a setoff against any loss or
damage arising from the breach, and said withholding shall not constitute breach
of this Agreement. Any amounts so withheld shall be deposited by the withholding
party into an interest-bearing escrow account. If the breaching party cures the
breach within the sixty (60) day cure period and this Agreement is not
terminated, then the withholding party shall promptly pay to the other party the
withheld amount, less that portion of such amount which was applied as a setoff.
Notwithstanding the foregoing provision, if Abbott gives notice of breach to
VIVUS, Abbott may withhold other payments pursuant to this Article 17.2 but
shall not be entitled to withhold payment for Product actually ordered by and
delivered to Abbott pursuant to Article 5 of this Agreement.

17.3 Insolvency or Bankruptcy. Either party may, in addition to any other
remedies available to it by law or in equity, terminate this Agreement, upon
thirty (30) days' written notice to the other party in the event the other party
shall have become insolvent or bankrupt, or shall have made an assignment for
the benefit of its creditors, or there shall have been appointed a trustee or
receiver of the other party or for all or a substantial part of its property, or
any case or proceeding shall have been commenced or other action taken by or
against the other party in bankruptcy or




                                 Page 33 of 55
<PAGE>   34

seeking reorganization, liquidation, dissolution, winding-up, arrangement,
composition or readjustment of its debts or any relief under any bankruptcy,
insolvency, reorganization or other similar act or law of any jurisdiction now
or hereinafter in effect.

17.4 Serious Events. Should there occur serious and unexpected events which,
from a reasonable pharmaceutical company's point of view, would make it
impossible or impracticable to pursue the commercialization of the Products,
including but not limited to a serious adverse event associated with the
Products, either party may, with full consultation with the other party,
terminate this Agreement upon thirty (30) days' written notice. Termination by a
party in good faith pursuant to this Article 17.4 shall not, in itself,
constitute a basis for any claim for compensation or other remedies by the other
party.

17.5 Lack of Commercial Viability. Abbott may terminate this Agreement, on a
country-by-country and Product-by-Product basis, upon one hundred eighty (180)
days' notice if, in Abbott's reasonable commercial judgement, the Product(s) are
not commercially viable in such country. In the event that Abbott terminates
this Agreement for one but not both of the Products in a country of the
Territory under this Article 17.5, all rights to use and sell such Product in
such country shall revert to VIVUS as of the effective date of such termination,
and Abbott shall ensure that all registrations and Regulatory Approvals for such
Product in such country shall be promptly assigned to VIVUS. In the event that
Abbott terminates this Agreement for both Products in a country of the Territory
under this Article 17.5, such country shall cease to be part of the Territory
for all purposes of this Agreement, all rights to use and sell Products in such
country shall revert to VIVUS as of the effective date of such termination, and
Abbott shall ensure that all registrations and Regulatory Approvals for the
Products in such country shall be promptly assigned to VIVUS. Termination by
Abbott in good faith pursuant to this Article 17.5 shall not, in itself,
constitute a basis for any claim for compensation or other remedies by the other
party.

17.6 Change of Control or Ownership. Either party may terminate this Agreement
upon thirty (30) days' written notice if the ownership or control of at least
fifty percent (50%) of the assets or voting securities of the other party are
transferred and, in the non-changing party's reasonable judgement, the other
party's new owner or controlling entity is a competitor of the non-changing
party in the field of erectile dysfunction.


17.7 Survival of Liability. Except as expressly provided otherwise in this
Agreement, termination, expiration, cancellation or abandonment of this
Agreement through any means and




                                 Page 34 of 55
<PAGE>   35

for any reason shall not relieve the parties of any obligation accruing prior
thereto and shall be without prejudice to the rights and remedies of either
party with respect to any antecedent breach of any provision of this Agreement.

17.8 Remaining Inventory. Abbott shall maintain a normal level of inventory of
the Products prior to expiration or termination of this Agreement, and shall
have a period of six (6) months from the date of termination of this Agreement
during which it may sell its remaining inventory of Products, provided it sell
such inventory in a manner substantially similar to the manner in which it was
selling Products prior to the termination.

17.9 Survival. Upon expiration or termination of this Agreement, all rights and
obligations of the parties under this Agreement shall terminate except those
rights and obligations described in Articles 1, 4.6, 10.1, 12.6, 17, 18, 19 and
20.

this Agreement, VIVUS shall indemnify, defend and hold Abbott, its directors,
employees, agents and representatives (including but not limited to Abbott's
Affiliates and sublicensees) harmless from and against all claims, causes of
action, settlement costs (including but not limited to reasonable attorney's
fees and expenses) losses or liabilities of any kind which:

    (A) arise from or are attributable to any negligent act or omission or
        willful misconduct on the part of VIVUS or its Affiliates, or its or
        their directors, employees, agents or representatives relating to any of
        VIVUS's obligations under this Agreement, including but not limited to
        any breach of a representation or warranty;

    (B) arise from or are attributable to a defect in the MUSE Product or in the
        manufacture of a Product, or from the failure of a Product to meet the
        Specifications and the Manufacturing Standards, including any theory of
        strict liability or any other theory of product liability, and which in
        either case are not otherwise attributable to any negligent act or
        omission or willful misconduct on the part of Abbott, its directors,
        employees, agents or representatives (including, but not limited to,
        Abbott's Affiliates); or

    (C) arise from or are attributable to any act or omission of VIVUS or Astra
        AB or, respectively, its Affiliates, or its or their directors,
        employees, agents or




                                 Page 35 of 55
<PAGE>   36

        representatives relating to the Astra Agreement, or any act or omission
        of Abbott or its Affiliates, or its or their directors, employees,
        agents or representatives which allegedly causes harm or damage or loss
        of rights to Astra AB or its Affiliates, or its or their directors,
        employees, agents, shareholders or representatives in connection with
        the Astra Agreement.

18.2 By Abbott. In addition to indemnification expressly provided elsewhere in
this Agreement, Abbott shall indemnify, defend and hold VIVUS, its directors,
employees, agents and representatives harmless from and against all claims,
causes of action, settlement costs (including but not limited to reasonable
attorney's fees and expenses) losses or liabilities of any kind which:

    (A) arise from or are attributable to any negligent act or omission or
        willful misconduct on the part of Abbott, its directors, employees,
        agents or representatives relating to any of its obligations under this
        Agreement; or

    (B) arise from or are attributable to the storage, use, sale, marketing and
        promotion of the Products by Abbott in the Territory and which in either
        case are not otherwise attributable to a defect in the MUSE Product or
        in the manufacture of a Product or the failure of a Product to meet the
        Specifications and Manufacturing Standards as set forth in Article
        18.1(B) above, and which in either case are not otherwise attributable
        to any negligent act or omission or willful misconduct on the part of
        VIVUS, its directors, employees, agents or representatives

18.3 Condition of Indemnification. If either party expects to seek
indemnification under this Article, it shall promptly give notice to the
indemnifying party of the basis for such claim of indemnification. If
indemnification is sought as a result of any third party claim or suit, such
notice to the indemnifying party shall be within fifteen (15) days after receipt
by the other party of such claim or suit (if to Abbott, notice to Abbott
Laboratories, Risk Management, D-317, 100 Abbott Park Road, Abbott Park, IL
60064-3500, with copy to the Abbott persons identified in Article 20.5 below; if
to VIVUS, notice as set forth in Article 20.5 below); provided, however, that
the failure to give notice within such time period shall not relieve the
indemnifying party of its obligation to indemnify unless it shall be materially
prejudiced by the failure. The indemnifying party shall have full control over
the defense of such claim or suit; provided that the indemnified party shall
have the right to participate, at its own expense, with counsel of its own
choosing, in such defense. The indemnified party shall fully cooperate with the




                                 Page 36 of 55
<PAGE>   37

indemnifying party in the defense of all such claims or suits. The indemnifying
party shall make no offer of settlement, settlement or compromise without the
prior written consent of the indemnified party (which consent shall not be
unreasonably withheld) unless such settlement fully releases the indemnified
party without any liability, loss, cost or obligation.

18.4 Term of Indemnification. The obligations of the parties set forth in this
Article 18 shall apply during the term of this Agreement and for a period of
five (5) years after the date of termination in whole or expiration of this
Agreement or any extension thereof.

ARTICLE 19 - CONFIDENTIALITY AND DISCLOSURE

19.1 Confidentiality. Neither party shall use or disclose any Confidential
Information received by it pursuant to this Agreement without the prior written
consent of the other. This obligation shall continue for a period of seven (7)
years after expiration or termination of this Agreement.

19.2 Disclosure. Nothing contained in this Article shall be construed to
restrict the parties from disclosing Confidential Information as required: (i)
for regulatory, tax, securities or customs reasons, (ii) by court or other
government order, (iii) for confidential audit purposes, or, (iv) from using
such Confidential Information as is reasonably necessary to perform acts
permitted by this Agreement, including the registration, marketing, sale or use
of the Product; provided that the disclosing party shall, in the event of
disclosure under Articles (i) or (ii) above, provide the other party with not
less than five (5) business days notice prior to disclosure (except where the
disclosing party itself receives less than five (5) business days prior notice,
in which case the disclosing party shall immediately notify the other party),
and the disclosing party shall fully cooperate with the other party to the
extent permitted by law, so that the other party may make any objections and/or
secure any protective provisions it deems reasonably necessary.

ARTICLE 20 - MISCELLANEOUS

20.1 Assignment. This Agreement may not be assigned or otherwise transferred,
nor, except as expressly provided hereunder, may any right or obligation
hereunder be assigned or transferred by either party without the prior written
consent of the other party; provided, however, that either VIVUS or Abbott may,
without such consent, assign this Agreement and its rights and obligations
hereunder in connection with the transfer or sale of all or substantially all of
its assets, its merger or consolidation or any similar transaction, and that
Abbott may, without




                                 Page 37 of 55
<PAGE>   38

such consent, assign this Agreement and its rights and obligations hereunder to
one or more of its Affiliates. Any permitted assignee shall assume all
obligations of its assignor under this Agreement.

20.2 Sublicensees. In the event that Abbott grants sublicenses under Article 2,
Abbott shall ensure that such sublicensees shall abide by all the obligations of

20.3 Damages. Notwithstanding any provision in this Agreement to the contrary,
in no event shall a party hereto be liable to the other party for any indirect
or consequential damages, including but not limited to loss of profits or
business opportunity.

20.4 Severability. Each party intends not to violate any public policy,
statutory or common law, rule, regulation, treaty or decision of any government
agency or executive body thereof of any country or community or association of
countries. If any term or provision of this Agreement is held to be invalid,
illegal or unenforceable by a court or other governmental authority of competent
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other term or provision of this Agreement, which shall remain in full force
and effect. The holding of a term or provision to be invalid, illegal or
unenforceable in a jurisdiction shall not have any effect on the application of
the term or provision in any other jurisdiction.

20.5 Notices. Any consent or notice required or permitted to be given or made
under this Agreement by one party to the other shall be in writing, delivered
personally or by facsimile (and promptly confirmed by personal delivery,

Exhibit 20.11 (p.1 of 5)



                         Alternative Dispute Resolution


                     The parties recognize that bona fide disputes as to certain
                     matters may arise from time to time during the term of this
                     Agreement which relate to either party's rights and/or
                     obligations. To have such a dispute resolved by this
                     Alternative Dispute Resolution ("ADR") provision, a party
                     first must send written notice of the dispute to the other
                     party for attempted resolution by good faith negotiations
                     between their respective presidents (or their designees) of
                     the affected subsidiaries, divisions, or business units
                     within twenty-eight (28) days after such notice is received
                     (all references to "days" in this ADR provision are to
                     calendar days).

                     If the matter has not been resolved within twenty-eight
                     (28) days of the notice of dispute, or if the parties fail
                     to meet within such twenty-eight (28) days, either party
                     may initiate an ADR proceeding as provided herein. The
                     parties shall have the right to be represented by counsel
                     in such a proceeding.

                     1. To begin an ADR proceeding, a party shall provide
                     written notice to the other party of the issues to be
                     resolved by ADR. Within fourteen (14) days after its
                     receipt of such notice, the other party may, by written
                     notice to the party initiating the ADR, add additional
                     issues to be resolved within the same ADR.

                     2. Within twenty-one (21) days following receipt of the
                     original ADR notice, the parties shall select a mutually
                     acceptable neutral to preside in the resolution of any
                     disputes in this ADR proceeding. If the parties are unable
                     to agree on a mutually acceptable neutral within such
                     period, either party may request the President of the CPR
                     Institute for Dispute Resolution ("CPR"), 366 Madison
                     Avenue, 14th Floor, New York, New York 10017, to select a
                     neutral pursuant to the following procedures:

                                (a) The CPR shall submit to the parties a list
                     of not less than five (5) candidates within fourteen (14)
                     days after receipt of the request, along with a Curriculum
                     Vitae for each candidate. No candidate shall be an
                     employee, director, or shareholder of either party or any
                     of their subsidiaries or affiliates.

Exhibit 20.11 (p.2 of 5)



                                (b) Such list shall include a statement of
                     disclosure by each candidate of any circumstances likely to
                     affect his or her impartiality.

                                (c) Each party shall number the candidates in
                     order of preference (with the number one (1) signifying the
                     greatest preference) and shall deliver the list to the CPR
                     within seven (7) days following receipt of the list of
                     candidates. If a party believes a conflict of interest
                     exists regarding any of the candidates, that party shall
                     provide a written explanation of the conflict to the CPR
                     along with its list showing its order of preference for the
                     candidates. Any party failing to return a list of
                     preferences on time shall be deemed to have no order of
                     preference.

                                (d) If the parties collectively have identified
                     fewer than three (3) candidates deemed to have conflicts,
                     the CPR immediately shall designate as the neutral the
                     candidate for whom the parties collectively have indicated
                     the greatest preference. If a tie should result between two
                     candidates, the CPR may designate either candidate. If the
                     parties collectively have identified three (3) or more
                     candidates deemed to have conflicts, the CPR shall review
                     the explanations regarding conflicts and, in its sole
                     discretion, may either (i) immediately designate as the
                     neutral the candidate for whom the parties collectively
                     have indicated the greatest preference, or (ii) issue a new
                     list of not less than five (5) candidates, in which case
                     the procedures set forth in subparagraphs 2(a) - 2(d) shall
                     be repeated.

                     3. No earlier than twenty-eight (28) days or later than
                     fifty-six (56) days after selection, the neutral shall hold
                     a hearing to resolve each of the issues identified by the
                     parties. The ADR proceeding shall take place at a location
                     agreed upon by the parties. If the parties cannot agree,
                     the neutral shall designate a location other than the
                     principal place of business of either party or any of their
                     subsidiaries or affiliates.

                     4. At least seven (7) days prior to the hearing, each party
                     shall submit the following to the other party and the
                     neutral:

                                (a) a copy of all exhibits on which such party
                     intends to rely in any oral or written presentation to the
                     neutral;

                                (b) a list of any witnesses such party intends
                     to call at the hearing, and a short summary of the
                     anticipated testimony of each witness;

Exhibit 20.11 (p.3 of 5)



                                (c) a proposed ruling on each issue to be
                     resolved, together with a request for a specific damage
                     award or other remedy for each issue. The proposed rulings
                     and remedies shall not contain any recitation of the facts
                     or any legal arguments and shall not exceed one (1) page
                     per issue.

                                (d) a brief in support of such party's proposed
                     rulings and remedies, provided that the brief shall not
                     exceed twenty (20) pages. This page limitation shall apply
                     regardless of the number of issues raised in the ADR
                     proceeding.

                     Except as expressly set forth in subparagraphs 4(a) - 4(d),
                     no discovery shall be required or permitted by any means,
                     including depositions, interrogatories, requests for
                     admissions, or production of documents.

                     5. The hearing shall be conducted on two (2) consecutive
                     days and shall be governed by the following rules:

                                (a) Each party shall be entitled to five (5)
                     hours of hearing time to present its case. The neutral
                     shall determine whether each party has had the five (5)
                     hours to which it is entitled.

                                (b) Each party shall be entitled, but not
                     required, to make an opening statement, to present regular
                     and rebuttal testimony, documents or other evidence, to
                     cross-examine witnesses, and to make a closing argument.
                     Cross-examination of witnesses shall occur immediately
                     after their direct testimony, and cross-examination time
                     shall be charged against the party conducting the
                     cross-examination.

                                (c) The party initiating the ADR shall begin the
                     hearing and, if it chooses to make an opening statement,
                     shall address not only issues it raised but also any issues
                     raised by the responding party. The responding party, if it
                     chooses to make an opening statement, also shall address
                     all issues raised in the ADR. Thereafter, the presentation
                     of regular and rebuttal testimony and documents, other
                     evidence, and closing arguments shall proceed in the same
                     sequence.

                                (d) Except when testifying, witnesses shall be
                     excluded from the hearing until closing arguments.

Exhibit 20.11 (p.4 of 5)



                                (e) Settlement negotiations, including any
                     statements made therein, shall not be admissible under any
                     circumstances. Affidavits prepared for purposes of the ADR
                     hearing also shall not be admissible. As to all other
                     matters, the neutral shall have sole discretion regarding
                     the admissibility of any evidence.

                     6. Within seven (7) days following completion of the
                     hearing, each party may submit to the other party and the
                     neutral a post-hearing brief in support of its proposed
                     rulings and remedies, provided that such brief shall not
                     contain or discuss any new evidence and shall not exceed
                     ten (10) pages. This page limitation shall apply regardless
                     of the number of issues raised in the ADR proceeding.

                     7. The neutral shall rule on each disputed issue within
                     fourteen (14) days following completion of the hearing.
                     Such ruling shall adopt in its entirety the proposed ruling
                     and remedy of one of the parties on each disputed issue but
                     may adopt one party's proposed rulings and remedies on some
                     issues and the other party's proposed rulings and remedies
                     on other issues. The neutral shall not issue any written
                     opinion or otherwise explain the basis of the ruling.

                     8. The neutral shall be paid a reasonable fee plus
                     expenses. These fees and expenses, along with the
                     reasonable legal fees and expenses of the prevailing party
                     (including all expert witness fees and expenses), the fees
                     and expenses of a court reporter, and any expenses for a
                     hearing room, shall be paid as follows:

                                (a) If the neutral rules in favor of one party
                     on all disputed issues in the ADR, the losing party shall
                     pay 100% of such fees and expenses.

                                (b) If the neutral rules in favor of one party
                     on some issues and the other party on other issues, the
                     neutral shall issue with the rulings a written
                     determination as to how such fees and expenses shall be
                     allocated between the parties. The neutral shall allocate
                     fees and expenses in a way that bears a reasonable
                     relationship to the outcome of the ADR, with the party
                     prevailing on more issues, or on issues of greater value or
                     gravity, recovering a relatively larger share of its legal
                     fees and expenses.

                     Exhibit 20.11 (p.5 of 5)



                     9. The rulings of the neutral and the allocation of fees
                     and expenses shall be binding, non-reviewable, and
                     non-appealable, and may be entered as a final judgment in
                     any court having jurisdiction.

                     10. Except as provided in paragraph 9 or as required by
                     law, the existence of the dispute, any settlement
                     negotiations, the ADR hearing, any submissions (including
                     exhibits, testimony, proposed rulings, and briefs), and the
                     rulings shall be deemed Confidential Information. The
                     neutral shall have the authority to impose sanctions for
                     unauthorized disclosure of Confidential Information.
