         2.5     VIVUS No Conflict.  VIVUS agrees that it will grant no rights
in the Territory to Third Parties which would conflict with the rights granted

3.       DEVELOPMENT AND MARKETING

         3.1     Joint Board.  Promptly after the Effective Date the parties
shall establish a Joint Development and Marketing Board ("JDMB") to oversee the
regulatory activities relating to the Product in the Territory, review and
discuss overall plans for the commercialization and marketing of the Product,
coordinate the exchange of information between the parties regarding the
marketing and sale of Product in the Territory and to undertake and/or approve
such other matters as are provided for the JDMB under this Agreement.  The JDMB
will consist of up to three (3) representatives from each party.  The JDMB
shall meet at least quarterly during the first two (2) years after the
Effective Date at mutually agreeable locations outside the United States or, if
mutually agreeable, by teleconference and thereafter as necessary.  Decisions
of the JDMB shall be by unanimous approval; provided, however, if the JDMB
cannot reach agreement on a matter, either party may refer the dispute to the
Chief Executive Officer of VIVUS and the President of Janssen-Ortho, Canada,
who shall meet promptly and negotiate in good faith to resolve any such dispute
within 30 days of any such referral.  If despite such good faith efforts, the
parties are unable to resolve such dispute, [*].

         3.2     Development.  The JDMB will discuss the design and
implementation of clinical trials for Product in the Territory.  For at least
the First Product in each country of the Territory and further Products that
Janssen intends to distribute hereunder at its discretion Janssen or its
Subdistributor shall, at their sole expense, carry out the remaining
preclinical and clinical development of the Products for the Territory to
achieve MAA Approval and shall keep the JDMB reasonably informed of its
activities.  [*]  Janssen shall not conduct, or authorize, encourage, assist or
contract with any Third Party to conduct any clinical testing of a Product
without VIVUS' prior approval, not unreasonably withheld, but subject to VIVUS'
right under Section 3.1 above to control the design and protocols of any such
clinical testing.

         3.3     Regulatory Approvals/MAAs.  For at least the First Product in
each country of the Territory and further Products that Janssen intends to
distribute hereunder at its discretion, Janssen shall be responsible, at its
sole expense, for filing MAAs for each Product in the Territory up to and
including MAA Approval and thereafter maintain such MAA Approvals.  All such
activity shall be done in full consultation with the JDMB.  Janssen shall use
reasonable efforts to obtain such MAA

*Confidential treatment requested pursuant to a request for confidential

<PAGE>   10

Approvals for the First Product as soon as practicable in each country within
the Territory, consistent generally with the efforts it makes for its other
important products.  In connection with Janssen's filing of MAAs, VIVUS shall
provide Janssen with a copy in English or translations already completed by
VIVUS, of all available information and data required to prepare appropriate
regulatory submissions affecting approval to market or of product pricing.
Without limiting the foregoing, in the event that filing for the necessary MAAs
with the appropriate regulatory agency in any country within the Territory
requires access to VIVUS' new drug application for the Product filed with the
U.S. FDA ("NDA"), VIVUS shall at its option (i) to the extent legally possible
in such country, file the MAA on behalf of Janssen, in which case Janssen shall
reimburse VIVUS' reasonable out-of-pocket expenses related to such filing, or
(ii) provide the NDA to Janssen solely for the purpose of making such MAA
filing.  VIVUS agrees to reasonably assist Janssen in responding to any
questions raised by the regulatory authorities.  This support may include, but
not be limited to, attending meetings with Janssen and local regulators in
North America to address specific aspects of the Product as part of the review
process.  [*]  All MAA filings will be in the name of VIVUS and Janssen except
where otherwise required by local law.  Janssen shall ensure that of all
registration and regulatory approvals are assigned back and sole ownership
transferred to VIVUS promptly upon termination of Janssen's distribution rights
with respect to the Product in such country to the extent permitted by
applicable laws.

         3.4     Marketing Plans.

                 3.4.1    General.   Janssen shall prepare reasonably detailed
marketing plans for the Territory, generally including country- by-country
plans, such plans to include plans related to the prelaunch, launch, promotion
and sale of Product, and which plans shall be shared with the JDMB (the
"Marketing Plans").  The Marketing Plans shall be designed to fulfill Janssen's
undertakings pursuant to Section 4.1 below.  Notwithstanding anything herein to
the contrary, subject to Section 3.1 above, the Marketing Plan for Canada
except for pricing shall be subject to approval by the JDMB.  Subject to the
provisions of this Agreement, and subject to compliance with the Marketing
Plans, Janssen shall have full control and authority of commercialization of
Product in the Territory and implementation of the Marketing Plans, at
Janssen's expense.  Janssen shall implement the Marketing Plans, and the JDMB
will review the progress of Janssen's marketing efforts under the Marketing
Plans.  Janssen agrees to keep the JDMB informed of the activities of Janssen
and its Subdistributors with respect to Products in the Territory.  VIVUS
agrees to keep the JDMB informed of key marketing strategies or plans that it
has developed or experiences that it has gained in marketing the Product
outside the Territory to the extent VIVUS has the right to do so.

                 3.4.2    VIVUS Approval.  Any claim, message or other material
part of promotional materials, Samples, advertising and materials for training
sales representatives with respect to Product, relating to uses, properties,
efficacy or positioning of Product, which has not previously been approved or
used by VIVUS or VIVUS Inc. in its own promotional or training activities,
shall be provided by Janssen to VIVUS along with an English translation
thereof, as applicable, and subject to review and approval by VIVUS prior to
the use by Janssen and its Subdistributors.  VIVUS shall use reasonable efforts
to complete any such review and respond to Janssen within fourteen (14) days
from notification by Janssen to VIVUS of the relevant matter.

         3.5     Exchange of Information.  Each party shall keep appropriate
records relating to the activities contemplated by this Article 3, and shall
report to the other party on the status of such activities on a regular basis.
The parties shall exchange data and information relating to Product development
to the extent reasonably necessary or appropriate, and each party shall have
the right to use such information received from the other in connection with
exercising its rights and performing its obligations under this Agreement.  In
fulfilling its obligations to report or exchange information under this Article
3, delivery by a party in writing to a member of the JDMB of the other party
will be considered sufficient.

         3.6     Adverse Experiences.  With respect to adverse drug experiences
relating to the Product, the parties shall report to the appropriate regulatory
authorities in the countries in which the Product is being developed or
commercialized, in accordance with the appropriate laws and regulations of the
relevant countries and authorities and Janssen shall ensure that its
Subdistributors comply with such reporting obligations.  Such reporting
activities within the Territory shall be coordinated by the JDMB where time and
law permit.  A party shall simultaneously with reporting any adverse drug
experience relating to the Product to the appropriate regulatory authorities of
any country or learning that a Third Party has reported an adverse drug
experience relating to the Product to an appropriate regulatory authority of
any country, report such adverse drug experience to the other party.  As soon
as is reasonable after the Effective Date, VIVUS will report to Janssen any
adverse drug experience relating to the Product of which it is aware that has
been reported to the appropriate regulatory authorities of any country.

4.       COMMERCIALIZATION AND PROMOTION

         4.1     Janssen Commercialization.

                 4.1.1    Diligence.  Janssen shall [*] (a) to launch the First

MAA Approval for such Product; and (b) after the First Commercial Sale of a
Product in a country, to achieve high volume sales of Product in such country.
Without limiting the foregoing, Janssen agrees to spend within the Territory on
promotion of the First Product, [*] after the First Commercial Sale of the
First Product in the first Major Country.

                 4.1.2    Failure to Sell.  If Janssen fails to launch the
First Product in any country in the Territory [*] from the date of MAA Approval
for such Product in such country, then such country shall cease to be part of
the Territory for all purposes of this Agreement, and all rights to package,
label, market, sell and distribute Product in such country shall revert to
VIVUS.  In countries where price approval of the First Product is required,
then the requirement for launch [*] after MAA Approval in the case where the
failure to launch is due to lack of price approval at a level no greater than
the price charged in other countries of the Territory and Janssen is exerting
reasonable efforts to obtain such price approval. In addition, if Janssen
decides, in its sole discretion, not to launch the First Product or not to
continue sales of at least one Product in any particular or all countries on
the terms of this Agreement Janssen may [*] cancel the launch or discontinue
sales in such country or countries and such country or countries shall cease to
be part of the Territory for all purposes of this Agreement, and all rights to
package, label, market, sell and distribute Product in such country shall
immediately revert to VIVUS. In the event a [*]

                 4.1.3    Subsequent Products.  With respect to each Product

for such Subsequent Product (i) file the appropriate MAAs necessary to market
and distribute such Subsequent Product in at least each of the Major Countries
and one (1) of Mexico, South Korea or Taiwan and use reasonable efforts to
obtain MAA Approvals for such Subsequent Product as soon as practicable in each
such country; or (ii) pay to VIVUS all amounts due for such Subsequent Product
under the appropriate clause of Section 6.1 that would otherwise be due upon
MAA Approval in both of the Major Countries and in Mexico; provided, however,
in the event that Janssen elects not to perform either (i) or (ii) above, then
such Subsequent Product shall be excluded from the definition of Product for
all purposes under this Agreement, including without limitation Sections 2.1
and 2.4 above, and VIVUS (itself or through an Affiliate or Third Party) shall
have the right to package, label, distribute, market and sell such Subsequent
Product in the Territory.

         4.2     Training.  VIVUS will provide a one-time training in English
for Janssen's English speaking sales and marketing management personnel with
respect to the Product at a first location of Janssen's choosing in the far
east and a second location of Janssen's choosing in Canada and will provide to
Janssen training materials for the Product prepared by VIVUS for use in

specifications, a current copy of which is attached hereto as Exhibit B (as
reasonably modified from time to time by VIVUS according to Section 5.11 below,
"Specifications") or if as to such Product, [*], VIVUS fails to meet the GMP
Standards/Regulatory practices as warranted in Section 12.2.2, Janssen shall
promptly notify VIVUS after its discovery of non-conformity and Janssen shall
present reasonable evidence to VIVUS of such nonconformity.  VIVUS shall
replace, at no additional expense to Janssen, such non-conforming Product with
new Product which does conform with the Specifications.  VIVUS may analyze any
unit of Product rejected by Janssen for nonconformity and if it is objectively
established that the Product was conforming, then Janssen shall be responsible
for payment for any such units of Product.  VIVUS shall give Janssen written
instructions as to how Janssen should, at VIVUS' expense, dispose of any
non-conforming material, and such instructions shall comply with all
appropriate governmental requirements.  With respect to any Products, [*] that
do not conform to the applicable Specifications, Janssen shall not have the
right to return the same if such non-conformity could have been detected upon
reasonable inspection when first delivered and Janssen fails to identify and
notify VIVUS of the non-conformity within forty-five (45) days after receipt by
Janssen of the goods.  In such event Janssen shall be responsible to purchase
such goods, and the price thereof shall be the same as accidentally destroyed
units under Section 6.2.2 below.

         5.8     Suppliers.  Without limiting VIVUS' responsibility under this
Agreement, VIVUS shall have the right at any time, to satisfy its supply
obligations to Janssen hereunder, either in whole or in part through
arrangements with Third Parties engaged to perform services or supply
facilities or goods in connection with the manufacture, testing, and/or
packaging of Product, [*].  VIVUS shall ensure that all such facilities comply
with applicable regulations and will give Janssen written notice sufficiently
in advance of any such arrangement to determine whether such arrangement would
require changes to an MAA Approval application filed in the Territory.  VIVUS
shall bear the costs related to changing the MAA Approval application required
as a result of any such change in manufacturing arrangements.  As a matter of
routine supply, VIVUS shall supply Product to Janssen for the Territory from a
single manufacturing facility.

         5.9     VIVUS Cost of Goods.  VIVUS shall keep complete and accurate
records of VIVUS Cost of Goods, such records to be in a form required under
U.S. Generally Accepted Accounting Principles (GAAP), consistently applied.
Janssen shall have the right, to the extent payments were made to VIVUS on the
basis of VIVUS Cost of Goods, at Janssen's expense, through a certified public
accountant or other representative acceptable to VIVUS, to examine such records
during regular business hours during the life of this Agreement and for one (1)
year after its termination; provided, however, that such examination shall not
take place more often than once a year and shall not cover such records for
more than the preceding three (3) years and provided further that such
accountant shall report to Janssen only as to the accuracy of the records.  If
such examination reveals that VIVUS has over reported the VIVUS Cost of Goods
by more than [*] for the period of the examination then VIVUS shall promptly
reimburse Janssen for its out-of-pocket costs related to such examination plus
interest at [*] on any amounts over paid to VIVUS hereunder due to such over
reporting.  In any case if either party discovers a miscalculation of VIVUS
Cost of Goods the parties shall correctly calculate such amount and make all
necessary and appropriate adjustments to amounts paid and/or payable hereunder.

         5.10    Shortage of Supply.

                 5.10.1   Allocation.  In the event that VIVUS is unable to
supply both worldwide requirements of Product and quantities ordered by Janssen
under Section 5.5 above due to force majeure or otherwise, VIVUS shall allocate
the quantities of Product that VIVUS has in inventory, and that VIVUS is able
to produce, so that Janssen receives at least its proportional share of
available supplies as determined based on reasonable forecasts of Janssen,
VIVUS, VIVUS Inc. and VIVUS' other distributors.  SUCH ALLOCATION SHALL BE
JANSSEN'S SOLE REMEDY FOR VIVUS' FAILURE TO SUPPLY TO JANSSEN QUANTITIES OF
PRODUCT VIVUS IS OTHERWISE OBLIGATED TO SUPPLY UNDER THIS ARTICLE 5.  During
such periods as supply of Product is subject to allocation pursuant to this
Section 5.10, VIVUS agrees to use its best efforts to resolve the situation
within a reasonable amount of time.

                 5.10.2   Joint Manufacturing Team.  Without limiting the
provisions of Section 5.10.1 above, if at any time VIVUS becomes unable to
supply, or becomes aware that it will be unable to supply, quantities of
Product ordered by Janssen in accordance with Section 5.5 above VIVUS shall
promptly notify Janssen in writing.  In such event, at Janssen's request, the
parties shall establish a committee (the "Joint Manufacturing Team") consisting
of two (2) representatives from each party and the Joint Manufacturing Team
shall immediately convene to address such shortage, including locating
alternative suppliers and facilities to increase production and identifying
other actions necessary to resolve the shortage.  VIVUS agrees to disclose to
the Joint Manufacturing Team current production capacity for the Product and
the total sales orders and forecasts for worldwide requirements for Product for
[*] (as defined in Section 5.4 above) for Janssen, VIVUS, VIVUS Inc. and Third
Party distributors without disclosing the identity of Third Parties.  Subject
to Section 6.9.1(b) of that certain Distribution Agreement between VIVUS and
Astra AB dated May 29, 1996, VIVUS agrees to implement all measures established
by the Joint Manufacturing Team to remedy the shortage; and if the Joint
Manufacturing Team is unable to agree upon the appropriate measures, and the
Chief Executive Officer of VIVUS and the President of Janssen-Ortho Canada are

unable to agree on how to resolve the problem after negotiating in good faith,
VIVUS agrees to implement any reasonable suggestions made by Janssen's senior
executive for resolving the shortage.  In any event, both parties agree to
respond with the level of speed and diligence commensurate with the severity of
the shortage.

         5.11    Modification of Specifications.  VIVUS may, from time to time,
with the approval of Janssen, not unreasonably withheld, reasonably modify the
Specifications attached as Exhibit B.  Notice of such modifications to the
Specifications must be sufficiently in advance to determine whether such
modifications would require changes to an MAA application filed in the
Territory.  Where such modifications requires changes to the MAA application
for any Product [*], then VIVUS will be responsible for the costs associated
with such modifications.

6.       PAYMENTS

Products for which payments for MAA Approval have already been made to VIVUS
hereunder.  VIVUS is under no obligation to develop or market any follow on
products to the First Product.

         6.3     Discounting.  In the event that Janssen or its Subdistributor
sells Products to a Third Party who also purchases other products or services
from Janssen or its Affiliates, Janssen agrees not to, and to require its
Subdistributors not to, discount the purchase price of the Products to a
greater degree than Janssen or its Subdistributors, respectively, generally
discounts the price of its other products to such customer.  For purposes of
this provision "discounting" includes establishing the list price at lower than
Janssen's normal pricing level.  Without limiting the foregoing, Janssen agrees
not to, and to require its Subdistributors not to, treat Products in such a
manner that would disadvantage the Product in comparison with other products
offered for sale by Janssen or its Subdistributors.

         6.4     Sales Records.  Janssen shall keep and require its
Subdistributors to keep complete and accurate records of all Net Sales of
Product on a country-by-country basis.  VIVUS shall have the right, at VIVUS'
expense, through a certified public accountant or other representative, to
examine such records during regular business hours provided, however, that such
examination shall not take place more often than once a year and shall not
cover such records for more than the preceding three (3) years.  If such
examination reveals an underpayment to VIVUS in excess of [*] for any period
then Janssen shall promptly reimburse VIVUS for the costs of such examination
and pay the underpayment amount plus interest at [*].

         6.5     Provisional Payments.

                 6.5.1    Product Units.  Payments due to VIVUS under Sections
6.2.1 and 6.2.2 and 6.2.3 shall be provisionally made, on a per unit of
Product, [*] basis, as the case may be, within [*] of delivery to Janssen of
each unit of Product, [*].  The provisional payment shall be based on [*]
estimates by the parties of those variables necessary to calculate a
provisional transfer price in accordance with the provisions of the relevant
sections.  Such estimates will be made in good faith and shall be consistent
with internal estimates on which the party relies to plan capacity, gauge
performance or plan inventory.   [*] prior to the start of any relevant Janssen
accounting year, Janssen and VIVUS will make the estimates and supply to each
other the following data to establish a provisional transfer price for that
entire year.

        (a)     For Product supplied under 6.2.1, the provisional payment will
be based on the formula:

         [*]

where:

         6.6     Reconciliation.

                 6.6.1    Product Units.  The provisional transfer price under
which Product, and other materials supplied under Section 5.3 above, was
received will be reconciled to the actual transfer price as the required data
is available within sixty (60) days following the end of each Janssen
accounting quarter, provided that VIVUS provides Janssen with the actual cost
of good sold within thirty (30) days of the end of such quarter.  In the event
that the provisional payments by Janssen under Section 6.5 above were greater
than the amounts actually due under Section 6.2, Janssen shall be entitled to
credit such excess against future purchases of Product hereunder.

                 6.6.2    Timing.  No reconciliation shall be made under this
Section 6.6 with respect to units for which provisional payments were made
until the end of the quarter in which such units are sold or in the case of
Samples in the quarter they are distributed.

         6.7     China Royalty. Janssen agrees to pay to VIVUS a running royalty
of [*], sold by Janssen or its Subdistributors.  Notwithstanding the foregoing,
in the event that a non-royalty payment method would, because of changed
circumstances, be more advantageous for either party with respect to Product
[*], the parties agree to discuss in good faith the implementation such other
method; it being understood, however, that neither party would incur any
disadvantage as a result of such other method.

         6.8     Payment.  Within [*] after the end of each calendar quarter,
Janssen shall provide VIVUS with a true accounting of all payment obligations,
if any, owed in accordance with this Article 6, together with a statement
setting out all details necessary to calculate the amounts actually due
hereunder with respect to Net Sales made in that calendar quarter, including
units of Product sold on a country-by-country basis, gross sales of Product in
that calendar quarter including units of Product sold on a country-by-country
basis, Net Sales in that calendar quarter on a country-by-country basis, all
relevant deductions, and all relevant exchange rate conversions.  Any payments
due shall accompany such statement.

         6.9     Taxes.  The parties hereto acknowledge and understand that as
of the Effective Date, no withholding taxes or similar governmental charges are
required to be withheld on amounts to be paid to VIVUS hereunder.  In the event
that after the Effective Date withholding taxes or similar charges are required
by law to be withheld on behalf of VIVUS from amounts due to VIVUS hereunder,
Janssen shall deduct said taxes or charges from amounts due to VIVUS hereunder
and promptly pay the same to the applicable taxing authority; provided, however
that to the extent such withholding taxes or other charges become due as a
result of Janssen's assignment or other transfer of this Agreement to an
Affiliate or otherwise pursuant to Section 13.8 below or other change in the
structure of or the way Janssen does business, Janssen shall gross up all
amounts due to VIVUS

hereunder so that the amounts paid to VIVUS are not reduced by said taxes or
other charges.  Notwithstanding the foregoing, all amounts to be paid to VIVUS
pursuant to Section 6.7 shall not be reduced by any withholding taxes or
similar governmental charges (not including U.S. or Bermuda income tax on
VIVUS' income).  In regard to taxes or charges paid on behalf of VIVUS, Janssen
shall furnish VIVUS with proper evidence of the taxes paid.

         6.10    U.S. Dollars.  All sums due under this Agreement shall be
payable in U.S. dollars.  Monetary conversion from the currency of a foreign
country in which Product is sold into United States currency shall be
calculated at the actual average of the buying and selling rates of exchange
for the quarter in which such sales were made as such rates are reported, as of
the last business day of such quarter, by the Wall Street Journal (U.S.,
Eastern Edition).

7.       CONFIDENTIALITY

         7.1     Nondisclosure.  "Confidential Information" means any
information, data, or know-how which the disclosing party treats
confidentially, is in writing and is identified as confidential, or if
disclosed orally is indicated to be confidential at the time of disclosure and

Third Parties any Confidential Information received from the other party
without first obtaining the written consent of the disclosing party, except as

necessary, disclose information received from VIVUS to a Subdistributor of
Janssen, provided that each such Subdistributor has agreed in writing to
maintain the confidentiality of such information and not use such information
except as necessary to fulfill the purposes hereunder.  Janssen shall be fully
responsible for any breach by its Subdistributors of this Article 7.  Janssen
shall immediately notify VIVUS of any unauthorized use or disclosure of VIVUS'
information that it becomes aware of.  Without limiting the foregoing, Janssen
shall at its expense, upon request of VIVUS take all other steps necessary to
cease all unauthorized use or disclosure of VIVUS Confidential Information
obtained from Janssen or Subdistributor, or in the event VIVUS takes such
steps, Janssen shall reimburse all reasonable costs related thereto.

         7.3     Terms of Agreement.  No public announcement or other public
disclosure concerning the existence of or terms of this Agreement shall be
made, either directly or indirectly, by any party to





                                      -15-

recording purposes, without first obtaining the written approval of the other
party and Agreement upon the nature and text of such announcement or
disclosure.  The party desiring to make any such public announcement or other
disclosure shall provide the other party with a copy of the proposed
announcement or disclosure for review and comment in reasonably sufficient time
prior to public release.  Each party agrees that it shall cooperate fully with
the other with respect to all disclosures regarding this Agreement to the
Securities Exchange Commission and any other governmental or regulatory
agencies, including requests for confidential treatment of proprietary
information of either party included in any such disclosure.  In addition, each
party agrees not to disclose this Agreement or its terms to Third Parties,
except to professional advisors and potential financing sources and under
conditions that reasonably protect the confidentiality thereof.  The parties
will mutually agree upon the contents of a press release (and accompanying Q&A)
which may be issued upon the Effective Date, and thereafter the parties may
publicly disclose information contained in such press release or Q&A without
further approvals.

         7.4     Clinical Data.  All clinical and preclinical data disclosed by
VIVUS shall be deemed Confidential Information of VIVUS.

         7.5     Product Data.  Janssen shall not submit for written or oral
publication any scientific or medical manuscript, abstract or the like which
includes data or other information relating to the Product without first
obtaining the prior written consent of VIVUS.  The contribution of each party
shall be noted in all publications or presentations by acknowledgment or
coauthorship, whichever is appropriate.

8.       PATENT PROSECUTION AND LITIGATION

         8.1     Ownership of Inventions.  Janssen shall have and retain sole
and exclusive title to all inventions, discoveries and know how ("Inventions")
which are made during the term of this Agreement by Janssen, its employees,
agents, or other Third Parties acting under authority from Janssen working on
matters relating to and made using or comprising a Product and Janssen hereby
grants to VIVUS a non- exclusive, worldwide license, with the right to
sublicense, to such Inventions to make, have made, use and sell products for
any indication.

         8.2     Maintenance of Patents.

                 8.2.1    Filings.  As between Janssen and VIVUS, VIVUS shall,
at its expense, have responsibility for filing, prosecution and maintenance of
all Patents in the Territory.  Janssen shall have the right to review pending
Patent applications and make recommendations to VIVUS concerning them.  VIVUS
will consider in good faith all reasonable suggestions of Janssen with respect
to such pending applications.  VIVUS agrees to keep Janssen informed of the
course of Patent prosecution or other proceedings with respect to the Patents
within the Territory.  Janssen shall provide such Patent consultation to VIVUS
at no cost to VIVUS.  All information disclosed to Janssen under this Section
8.2 shall be deemed Confidential Information of VIVUS.  In the event that





                                      -16-
<PAGE>   22

VIVUS does not file or discontinues the prosecution or maintenance of any
Patents in the Territory, then Janssen may, at its expense, choose to continue
the same with the cooperation of VIVUS.

                 8.2.2    Extensions.  Janssen shall have the right but not the
obligation to seek extensions of the terms of Patents in the Territory.  At
Janssen's request, VIVUS shall either authorize Janssen to act as VIVUS' agent
for the purpose of making any application for any extensions of the term of
Patents and provide reasonable assistance therefor to Janssen or shall
diligently seek to obtain such extensions, in either event, at Janssen's
expense.

         8.3     Infringement by Product.  In the event of the institution of
any suit by a Third Party against Janssen for patent infringement involving the
manufacture, use, sale, distribution or marketing of Product anywhere in the
Territory during the term of this Agreement, Janssen shall promptly notify
VIVUS in writing.  Janssen shall have the right but not the obligation to
defend such suit against it.  Except in the case of a breach under Section
12.5, Janssen will have the right to offset [*] of the out-of-pocket costs of
defending such suit against any sums due VIVUS hereunder; provided that VIVUS
shall have the right to reasonably approve the plan of defense under which such
costs are incurred.  VIVUS and Janssen shall assist one another and cooperate
in any such litigation at the other's reasonable request without expense to the
requesting party, and in any event VIVUS may participate in any such suit with
counsel of its choice at its own expense.  Without limiting the foregoing,
Janssen may offset from amounts due to VIVUS hereunder [*] of amounts finally
awarded against and paid by Janssen to a Third Party to the extent the same
arise out of the Product's infringement of Third Party patent rights within the
Territory during the term of this Agreement.

         8.4     Third Party Infringement.  In the event that VIVUS or Janssen

expense and to include VIVUS as a nominal party plaintiff.  VIVUS shall keep
Janssen reasonably informed of its activities during the [*] period.  The party
conducting such action shall have full control over its conduct, including

Janssen shall assist one another and cooperate in any such litigation at the
other's reasonable request without expense to the requesting party.

         8.6     Status of Activities.  The parties shall keep one another
informed of the status of their respective activities regarding any litigation
or settlement thereof concerning Product within the Territory, provided however
that no settlement or consent judgment or other voluntary final disposition of
any suit defended or action brought by a party pursuant to this Article 8 may
be entered into without the consent of the other party if such settlement would
require the other party to be subject to an injunction or to make a monetary
payment or would otherwise adversely affect the other party's rights under this
Agreement.

         9.1     Display.  All packaging materials, labels and promotional

the "VIVUS" tradename in at least ten (10) point logo type.
    

         9.2     License.  VIVUS hereby grants to Janssen an exclusive,
royalty-free license, to use the VIVUS Trademark, or the VIVUS Alternative
Trademark in each country of the Territory for the term of this Agreement in
connection with the marketing and promotion of Product as contemplated in this
Agreement.  The ownership and all good will from the use of the VIVUS Trademark
and the VIVUS Alternative Trademark shall vest in and inure to the benefit of
VIVUS.

         9.3     Registration.  VIVUS agrees to file, register and maintain a
registration for the VIVUS Trademark in the countries of the Territory listed
on Exhibit E, as VIVUS is reasonably able under the circumstances, for the term
of this Agreement, at VIVUS' expense, for use with the Product.  In the event
that the VIVUS Trademark or VIVUS Alternative Trademark is unavailable for use
with the Product in one or more countries listed on Exhibit E, VIVUS agrees to
choose in consultation with Janssen a VIVUS Alternative Trademark.  Where VIVUS
agrees to the use of a VIVUS Alternative Trademark in a country, VIVUS agrees
to file, register and maintain a registration for the VIVUS Alternative
Trademark in such country, for the term of this Agreement, at VIVUS' expense,
for use with the Product in such country.

         9.4     Recordation.  In those countries where a trademark license
must be recorded, VIVUS will provide and record a separate trademark license
for the VIVUS Trademark and/or VIVUS Alternative Trademark.  Janssen shall
cooperate in the preparation and execution of such documents.

shall submit representative promotional materials, packaging, [*] using the
VIVUS Trademark and/or VIVUS Alternative Trademark  to VIVUS for VIVUS'
reasonable approval prior to the first use of such items and prior to any

responded within four (4) weeks after such submissions, VIVUS' approval will be
deemed to have been received.  For purposes of quality control, Janssen agrees
that for the [*] shall meet sufficient

standards of quality.  In the event that, after review, VIVUS determines that
[*] to meet acceptable standards of quality within a reasonable time.

         9.6     Termination of Rights.  Janssen's right to use the VIVUS
Trademark and the VIVUS Alternative Trademark shall terminate in each country
of the Territory in which Janssen's rights to distribute the Product expire or
are terminated in accordance with this Agreement.  Janssen shall ensure the
cancellation of any Trademark licenses recorded or entered into in such
countries in favor of or by or under authority of, Janssen or its
Subdistributors to the extent legally possible.

         9.7     Trademark Indemnity.  VIVUS agrees to defend and/or settle any
claim brought against Janssen or its Subdistributor by a Third Party arising
out of or resulting from Janssen or its Subdistributor use of the VIVUS
Trademark or the VIVUS Alternative Trademark or the tradename VIVUS in the
Territory in accordance with the terms and conditions of this Agreement during
the term of this Agreement.  VIVUS shall pay all resulting damages or
settlement amounts finally awarded against Janssen or its Subdistributor
(including reasonable attorneys' fees and court costs) which are attributable
to such claim during the term of this Agreement.  Notwithstanding the
foregoing, if the VIVUS Trademark or VIVUS Alternative Trademark or the
tradename VIVUS becomes, or in VIVUS' reasonable judgment may become, the
subject of any claim as a result of Janssen or its Subdistributors use thereof
in any country within the Territory, VIVUS may, upon notice to Janssen, request
that Janssen and/or its Subdistributor cease using the VIVUS Trademark or VIVUS
Alternative Trademark or the tradename VIVUS, as applicable, in such country.
Ninety (90) days after such a request by VIVUS, VIVUS' obligation to defend and
settle claims under this Section 9.7 will terminate to the extent any claims,
damages or expenses arise out of or result from use after such ninety (90)-day
period of said VIVUS Trademark or VIVUS Alternative Trademark or the tradename
VIVUS in such country.  The termination of VIVUS' obligation to defend and
settle claims is contingent upon VIVUS making available to Janssen, where VIVUS
is obligated to supply, adequate supplies of alternately labeled Product in a
timely manner sufficient to satisfy Janssen's demand therefor after the end of
such ninety (90) day period.  After VIVUS' request to cease using a trademark,
upon Janssen's request, VIVUS agrees to register a new trademark for use in the
said country in accordance with Section 9.3 above.

         9.8     Trademark Enforcement.  In the event that either party becomes
aware that a Third Party is misappropriating or otherwise misusing the VIVUS
Trademark or VIVUS Alternative Trademark, as the case may be, within the
Territory such party shall promptly notify the other party.   In which case,
the parties agree to discuss such misappropriation or misuse and cooperate to
develop a reasonable enforcement plan to deal with the same.  VIVUS shall bear
[*] and Janssen shall bear [*] of the costs and expenses incurred to bring an
action to enforce the VIVUS Trademark or VIVUS Alternative Trademark, as
appropriate, in accordance with the mutually agreed upon enforcement plan.
Likewise, any recovery from such an action shall be shared between the parties,
with VIVUS receiving [*] and Janssen receiving [*] to the extent such recovery
relates to misappropriation or misuse in the Territory during the term of this
Agreement.

13.      GENERAL PROVISIONS

         13.1    Force Majeure. If either party fails to perform any part of
this Agreement due to any cause beyond the reasonable control of such party,
the party so affected shall, upon giving written notice to the other party, be
excused from such performance, provided that such party shall use its
reasonable efforts to avoid or remove such causes of non-performance and shall
continue performance with the utmost dispatch whenever such causes are removed.
When such circumstances arise, the parties shall discuss what, if any,
modification of the terms of this Agreement may be required in order to arrive
at an equitable solution.

         13.2    Governing Law and Arbitration.  This Agreement shall be
governed by the laws of the State of California without reference to conflict
of law principles.  In the event of any dispute under this Agreement, both
parties shall endeavor to settle such dispute amicably between themselves.  In
the event that the parties fail to agree, such dispute shall be settled by
arbitration as follows:  Either party may by notice in writing to the other
require any issue in dispute to be submitted to arbitration in accordance with
this Section 13.2.  From the date of the notice in writing and until such time
as any matter has been finally settled by arbitration hereunder, the running of
the time periods in which a party must cure a breach of  this agreement shall
be suspended as to the subject matter of the dispute.  Such notice shall
contain a statement of the arbitrable issue forming the basis of the dispute
and the position of the moving party as to the proper resolution of that issue.
Within thirty (30) days after receipt of such notice, the responding party
shall submit to the moving party a statement of its conception of the
arbitrable issue in question and of its position as to the proper resolution of
that issue.  Within thirty (30)-days of the responding party's response, each
party shall appoint an independent arbitrator and give the other party written
notice thereof.  In the event a party shall fail to appoint an arbitrator and
provide written notice thereof to the other party within such thirty (30) day
period, an arbitrator shall be appointed for such party by the American
Arbitration Association, as promptly as practicable after request by the other
party.  Thereafter, the two (2) appointed arbitrators shall select a third
arbitrator within thirty (30) days after receipt of a list of proposed
arbitrators having expertise in the pharmaceutical industry proposed by the
American Arbitration Association.  If the two (2) arbitrators designated by the
parties are unable to agreed on the third arbitrator within





                                      -24-
<PAGE>   30
thirty (30) days, then either party with notice to the other party, may call
for such appointment by the American Arbitration Association of the third
arbitrator.  Regardless of the manner of his or her selection, the third
arbitrator shall be one who is qualified by knowledge and experience in the
pharmaceutical field.  Each arbitrator shall agree prior to his or her
appointment to hear the dispute promptly and render a decision as soon as
practicable thereafter.  The arbitration shall be conducted in English in
Chicago, Illinois, in accordance with the commercial arbitration rules or
successor rules then obtaining of the American Arbitration Association to the
extent not inconsistent with this Section 13.2.  The Agreement of two (2) of
the three (3) arbitrators shall be sufficient to render a decision.  The
decision of the panel shall be final and binding upon the parties and
enforcement thereof may be obtained in any court of competent jurisdiction.
The arbitrators may award costs and expenses, including reasonable attorneys'
fees, to the successful party, as the arbitrators deem appropriate. WITH
RESPECT TO DISPUTES REGARDING AMOUNTS DUE HEREUNDER THE PARTIES AND ARBITRATORS
SHALL USE ALL REASONABLE EFFORTS TO CONCLUDE THE ARBITRATION WITHIN ONE HUNDRED
TWENTY (120) DAYS FROM THE INITIAL NOTICE.

         13.3    Janssen Right of Inspection.  During the term of this

following:  (i) all manufacturing and quality control records for all
manufacture of the Product supplied by VIVUS hereunder and (ii) quality control
records of all starting materials used in the manufacture of a Product supplied
by VIVUS hereunder.  In addition, during the term of this Agreement, upon the
written request of Janssen, VIVUS shall permit Janssen's authorized
representative to inspect, at mutually agreeable times and during normal
business hours, the facilities where Product is manufactured for delivery to
Janssen hereunder for the purpose of verifying compliance with GMP and other
applicable regulatory standards.  VIVUS shall remedy any deficiencies
discovered as a result of such inspections as soon as reasonably possible upon
receipt notice of the same from Janssen.

         13.4    Waiver of Breach.  The failure of either party at any time to
require performance of any provision hereof shall not affect its rights at a
later time to enforce the same.  No waiver by either party of any condition or
term in any one or more instances shall be construed as a further or continuing
waiver of such condition or term or of another condition or term.

         13.5    Separability.  If any portion of this Agreement is held to be
illegal, void or ineffective, the remaining portions shall remain in full force
and effect and the parties will renegotiate the terms and conditions of this
Agreement to resolve any inequities.

         13.6    Entire Agreement.  This Agreement constitutes the entire
Agreement between the parties relating to the subject matter hereof and
supersedes all previous writings and understandings.  No terms or provisions of
this Agreement shall be varied or modified by any prior or subsequent
statement, conduct or act of either of the parties, except that the parties may
amend this Agreement by written instruments specifically referring to and
executed in the same manner as this Agreement.
