right and then Cypress shall be free to appoint a Third Party as sub-licensee
pursuant to the sublicense rights granted pursuant to Section 2.1(a) above.
Pierre Fabre shall have no rights under this Section 2.1(b) if the Negotiation
Period expires without Cypress and Pierre Fabre entering into a definitive

<PAGE>

following events with respect to a Licensed Product in the Field in the
United States by the time set forth opposite each such event; provided that the
timelines described below set forth on the following assumptions:

              (a) Cypress has filed an IND for the IR Formulation or the SR

30-day period after filing of the Initial IND, the FDA has removed any hold on
the Initial IND (the date specified in subsection (i) or (ii), as applicable,
being referred to herein as the "IND Clearance Date"). Consequently the
timelines below will be subject to adjustment as determined by the Steering
Committee if any formulation other than the IR Formulation and the SR
Formulation is used. The timelines for the following events begin on the first
day following the IND Clearance Date:

              (b) Commencement of Phase II Clinical Trial within [...***...]
after the IND Clearance Date.

Date, Pierre Fabre will take all necessary steps to provide to Cypress the IND
for Milnacipran filed with the FDA in the United States (No. 37,072) and shall
use commercially reasonable efforts to assist Cypress in filing the Initial IND.
In addition, and as far as it has not already done during the due-diligence
process carried out by Cypress prior to the Effective Date, Pierre Fabre shall
use commercially reasonable efforts to provide to Cypress any additional
available Pierre Fabre Know-How requested by Cypress which Cypress deem useful
for the submission of the Initial IND. Based on Pierre Fabre Know-How received
prior to the Effective Date and hereunder, Cypress shall prepare and submit to
the FDA the Initial IND on or before [...***...] and shall use all commercially
reasonable efforts to cause the IND Clearance Date to occur promptly and in any
event within [...***...] from the date of the submission of the Initial IND. In

7.   Supply of API and Transfer Price

     7.1  Supply by Pierre Fabre. Pierre Fabre agrees that it will manufacture
and supply to Cypress such quantities of API as requested by Cypress. The
parties agree that Pierre Fabre will be the exclusive supplier to Cypress of the
API and Cypress agrees that during the License Term, it shall purchase all of
its requirements for API from Pierre Fabre for clinical trials, samples and
commercial sales. Pierre Fabre shall remain the exclusive supplier of API for
Cypress as long as there is no generic competition in the Licensed Territory
taking at least a [...***...] market share of the Licensed Product in the Field
during [...***...]. Should any such generic competition appears in the Licensed
Territory, then Pierre Fabre will remain Cypress' exclusive supplier of API, as
long a Pierre Fabre can supply API to Cypress at a price no greater than
[...***...] more than the price charged by a Third Party generic supplier of
API. In the event Pierre Fabre is not able to provide the API at a price no
greater than [...***...] more than the price charged by a Third Party generic
supplier, Cypress may purchase API from Third Party suppliers; provided that the
API supplied by such Third Party complies with API Specifications as defined in
the Supply Agreement.

     7.2  Transfer Price. For API supplied by Pierre Fabre (other than for
clinical trials). Cypress will pay to Pierre Fabre a transfer price, equal to

                                      13.

<PAGE>

since the actual Average Net Selling Price for the Licensed Territory will not
be determinable when the quantities of API are shipped to Cypress, the parties
agree that (i) all deliveries of API to be made during each calendar quarter
will be invoiced on the basis of [...***...] of a tentative Average Net Selling
Price that will be agreed between the parties 60 days before each calendar
quarter, (ii) within 30 days from the end of each calendar quarter, once the
actual Average Net Selling Price for the calendar quarter concerned is
determined according to the provisions of Section 10, then a reconciliation will
be made between (x) the total value of deliveries invoiced by Pierre Fabre at
the tentative Average Net Selling Price and (y) the value of such deliveries at
the actual Average Net Selling Price. Any difference in favor of Pierre Fabre
will be subject to an invoice of Pierre Fabre and paid by Cypress within 30 days
and any difference in favor of Cypress will be credited against next deliveries
of API to be made by Pierre Fabre to Cypress. Notwithstanding the above, the
transfer price to be paid by Cypress to Pierre Fabre for API shall under no
circumstances be less than [...***...] per kilogram of API (the "Bottom Price").
Payments pursuant to this Section 7.2 and to Section 7.4 will be made by Cypress
to Pierre Fabre within 60 days date of invoice.

     7.3  Supply Agreement. Cypress and Pierre Fabre agree that within six
months of the Effective Date that they will enter into a purchase and supply
agreement with respect to API in accordance with the terms set forth in this

for all clinical trials of Licensed Products conducted by Cypress or its
sublicensees in the Licensed Territory at [...***...]. Until the parties enter
into the Supply Agreement, Pierre Fabre will manufacture API for clinical trials
in accordance with Sections 7.5 through 7.10.

     7.5  Forecasts and Purchase Orders. Within [...***...] following the
Effective Date, Cypress will provide to Pierre Fabre a forecast of its estimated
requirements of API and proposed delivery dates for API for the following
[...***...] period, which forecast shall be updated by Cypress each month
thereafter. The API requirements for the [...***...] of each rolling [...***...]
forecast shall be a binding purchase order, and the API requirements for the
[...***...] of each such forecast shall be a non-binding purchase order.

     7.6  Delivery and Acceptance. Pierre Fabre agrees to deliver the API in
such quantities and on such delivery dates as are specified in Cypress' binding
purchase orders. Pierre Fabre shall ship the API to Cypress or to the address
that Cypress designates at Cypress' expense. The shipping and packaging method
used will be at the discretion of Pierre Fabre, but should be sufficient to
ensure that the quantities of API will meet the API Specifications as defined in
the Supply Agreement. Deliveries shall be made Ex-Works Pierre Fabre's facility
(ICC Incoterms 2000) and shall be shipped to Cypress' address as set forth in
this Agreement, or as otherwise directed by Cypress in writing.

     7.7  Specifications; Testing. Pierre Fabre will perform standard analytical
testing that is mutually acceptable to the parties on each lot of API prior to
shipment. Pierre Fabre shall provide a Certificate of Analysis to Cypress or its
designated agent with each shipment of the API supplied hereunder. Such

current good manufacturing practices (cGMPs), as well as any further information
required by the relevant regulatory authorities that Cypress may have previously
notified Pierre Fabre is necessary. Cypress shall be under no obligation to
accept any shipment of the API without an accompanying Certificate of Analysis.

     7.8  Acceptance and Rejection.

          (a) Within 60 days of receipt of the API at Cypress' facilities or
such other destination as may be designated by Cypress, Cypress or its agent
shall perform such samplings and tests as are appropriate to determine whether
the API meets the API Specifications. If Cypress rejects any shipment of API,
Cypress shall within such 60-day period inform Pierre Fabre of its refusal to
accept the lot(s), and the reasons therefor; otherwise Cypress shall be deemed
to have accepted the lots.

          (b) Promptly following any notice of rejection of API by Cypress,
Pierre Fabre and Cypress agree to mutually determine whether the rejected API
conformed to the API Specifications. If Cypress and Pierre Fabre cannot agree
after a period of 60 days, they shall select a mutually acceptable independent
laboratory to perform tests on representative samples from the rejected portion
of the shipment. The results of such tests shall be binding upon Cypress and
Pierre Fabre.

          (c) If it is determined with or without reference to an independent
laboratory that the rejected API was non-conforming, Pierre Fabre shall at
Cypress' election, either make a replacement delivery free of any additional
charge, or reimburse Cypress the purchase price, including freight and insurance
(if the purchase price had actually been paid by Cypress) for the rejected API.
Rejected API shall be returned to Pierre Fabre or disposed of at Pierre Fabre's
expense in accordance with Pierre Fabre's instructions, in which case Cypress
shall deliver to Pierre Fabre an appropriate certificate of destruction.

     7.9  Manufacture of API Pierre Fabre will manufacture API in accordance
with the API Specifications, cGMPs and other applicable rules and regulations of
the FDA and other governmental or regulatory agencies with jurisdiction over the
manufacture, use or sale of the API, as then in effect. Pierre Fabre will be
responsible for manufacturing issues related to regulatory compliance. The
parties shall promptly notify each other of any new instructions or
specifications required by the FDA, and of other applicable United States rules
and regulations. The parties shall confer with each other with respect to the
best means to comply with such requirements and shall allocate any costs of
implementing such changes on an equitable basis.

     7.10 Access to Pierre Fabre Facility. Pierre Fabre will provide Cypress
with reasonable access, during business hours upon reasonable prior notice, to
Pierre Fabre's facilities where API is manufactured to review Pierre Fabre's
manufacturing operations and assess its compliance with cGMPs and quality
assurance standards and the opportunity to discuss any manufacturing issues with
Pierre Fabre's manufacturing and management personnel.

     7.11 Manufacture of the Licensed Product.

          (a) Pierre Fabre agrees that it will provide Cypress with reasonable
assistance in securing a Third Party manufacturer to produce Bulk Licensed
Product on behalf of Cypress if

                                      15.

account designated in writing by the party entitled to receive such payment,
unless otherwise specified in writing by such party.

     10.3 Withholding of Taxes. The party receiving payments under this
Agreement will pay any and all taxes levied on account of such payment. If any
taxes are required to be withheld by the paying party, it will (a) deduct such
taxes from the remitting payment, (b) timely pay the taxes to the proper taxing
authority, and (c) send proof of payment to the other party and certify its
receipt by the taxing authority within 60 days following such payment.

     10.4 Records and Audits. During the License Term and for a period of five
years thereafter, each party shall keep complete and accurate records pertaining
to gross sales and Net Sales of the Licensed Products, including the expenses
incurred by the selling party, in sufficient detail to permit the other party to
confirm the accuracy of all payments due hereunder. A party shall have the right
to cause an independent, certified public accountant reasonably acceptable to
the other party to audit such records to confirm Net Sales and payments for a
period covering not more than the preceding three years. Such audits may be
exercised during normal business hours upon reasonable prior written notice to
the audited party. Prompt adjustments shall be made by the parties to reflect
the results of such audit. The party causing such audit shall bear the full cost
of such audit unless such audit discloses a variance of more than 5% from the
amount of the Net Sales or payments due under this Agreement. In such case, the
audited party shall bear the full cost of such audit. In the event of
underpayment, the audited party shall promptly remit to the other party the
amount of any underpayment.

     10.5 Prohibited Payments. Notwithstanding any other provision of this
Agreement, if a party is prevented from paying any payments due hereunder by
virtue of the statutes, laws, codes or governmental regulations of the country
from which the payment is to be made, then such payments may be paid by
depositing funds in the currency in which accrued to the other party account in
a bank acceptable to such other party in the country whose currency is involved.

11.  Intellectual Property

     11.1 Patent Prosecution and Maintenance. Pierre Fabre shall be responsible
for prosecution and maintenance of all Pierre Fabre Patents at Pierre Fabre's
sole expense. Pierre Fabre shall consider in good faith the requests and
suggestions of Cypress with respect to strategies for prosecuting the Pierre
Fabre Patents in the Licensed Territory. Pierre Fabre shall keep Cypress
informed of progress with regard to the prosecution, maintenance, enforcement
and defense of the Pierre Fabre Patents by providing Cypress of copies of
official actions, amendments and responses with respect to such prosecution. In
the event that Pierre Fabre desires to abandon any Pierre Fabre Patent in the
Licensed Territory, Pierre Fabre shall provide reasonable prior written notice
to Cypress of such intention to abandon and provide Cypress an opportunity to
discuss with Pierre Fabre the possibility of assuming responsibility for such
Pierre Fabre Patent. If Cypress assumes responsibility for any Pierre Fabre
Patent, such Patent shall be assigned to Cypress and shall no longer be included
in the Pierre Fabre Patents subject to this Agreement.

     11.2 Cooperation of the Parties. Each party agrees to cooperate fully in
the prosecution of the Pierre Fabre Patents under this Agreement.

                                      19.

<PAGE>

     11.3 Infringement by Third Parties. Pierre Fabre and Cypress shall promptly
notify the other in writing of any alleged or threatened infringement or any
challenge to the validity of the Pierre Fabre Patents or any challenge to Pierre
Fabre's ownership of or Cypress' and/or its licensees' right to use, the Pierre
Fabre Patents of which they become aware. Both parties shall use their best
efforts in cooperating with each other to terminate such infringement without
litigation. Pierre Fabre shall have the sole right to bring and control any
action or proceeding with respect to infringement of any of the Pierre Fabre
Patents at its own expense and by counsel of its own choice. With respect to
infringement of any of the Pierre Fabre Patents in the Licensed Territory, if
Pierre Fabre fails to bring an action or proceeding within (a) 60 days following
the notice of alleged infringement or (b) 10 days before the time limit, if any,
set forth in the appropriate laws and regulations for the filing of such
actions, whichever comes first, Cypress shall have the right to bring and
control any such action at its own expense and by counsel of its own choice, and
Pierre Fabre shall have the right, at its own expense, to be represented in any
such action by counsel of its own choice. In the event a party brings an
infringement action, the other party shall cooperate fully, including if
required to bring such action, the furnishing of a power of attorney. Neither
party shall have the right to settle any infringement litigation under this
Section 11.3 relating to the Pierre Fabre Patents without the prior written
consent of the other party. Except as otherwise agreed to by the parties as part
of a cost-sharing arrangement, any recovery realized as a result of such
litigation, after reimbursement of any litigation expenses of Pierre Fabre and
Cypress, shall be retained by the party that brought and controlled such
litigation.

     11.4 Infringement of Third Party Rights. Each party shall promptly notify
the other in writing of any allegation by a Third Party that the activity of
either of the parties pursuant to this Agreement infringes or may infringe the
intellectual property rights of such Third Party. Cypress shall have the first
right to control any defense of any such claim alleging that the sale of
Licensed Products in the Field infringes any Third Party rights in the Licensed
Territory, at its own expense and by counsel of its own choice, and Pierre Fabre
shall have the right, at its own expense, to be represented in any such action
by counsel of its own choice. If Cypress fails to proceed in a timely fashion
with regard to such defense, Pierre Fabre shall have the right to control any
such defense of such claim at its own expense and by counsel of its own choice,
and Cypress shall have the right, at its own expense, to be represented in any
such action by counsel of its own choice. Pierre Fabre shall have the first
right to control any defense of any such claim alleging that the manufacture of
API or Licensed Products infringes any Third Party rights in the Licensed
Territory, at its own expense and by counsel of its own choice, and Cypress
shall have the right, at its own expense, to be represented in any such action
by counsel of its own choice. If Pierre Fabre fails to proceed in a timely
fashion with regard to such defense, Cypress shall have the right to control any
such defense of such claim at its own expense and by counsel of its own choice,
and Pierre Fabre shall have the right, at its own expense, to be represented in
any such action by counsel of its own choice. Pierre Fabre shall have the sole
right to control any defense of any such claim alleging infringement of any
Third Party rights outside the Licensed Territory, at its own expense and by
counsel of its own choice. Neither party shall have the right to settle any
patent infringement litigation under this Section 11.4 relating to the
manufacture or commercialization of Licensed Products in the Licensed Territory
without the consent of such other party.

shall keep confidential and shall not publish or otherwise disclose and shall
not use for any purpose other than as expressly provided for in this Agreement
any confidential information (including, without limitation, Information)
furnished to it by the other party pursuant to this Agreement (collectively,
"Confidential Information"). Each party may use such Confidential Information
only to the extent required to accomplish the purposes of this Agreement. Each
party will use at least the same standard of care as it uses to protect
proprietary or confidential information of its own to ensure that its employees,
agents, consultants and other representatives do not disclose or make any
unauthorized use of the Confidential Information. Each party will promptly
notify the other upon discovery of any unauthorized use or disclosure of the
Confidential Information.

     13.2 Exceptions. Confidential Information shall not include any information
which the receiving party can prove by competent written evidence:

          (a) is now, or hereafter becomes, through no act or failure to act on
the part of the receiving party, generally known or available;

          (b) is known by the receiving party at the time of receiving such
information, as evidenced by its records;

similar terms of confidentiality and non-use at least equivalent in scope to
those set forth in this Section 13.

     Notwithstanding the foregoing, in the event a party is required to make a
disclosure of the other party's Confidential Information pursuant to this
Section 13.3, it will, except where impracticable, give reasonable advance
notice to the other party of such disclosure and use efforts to secure
confidential treatment of such information at least as diligent as such party
would use to protect its own confidential information, but in no event less than
reasonable efforts. In any event, the parties agree to take all reasonable
action to avoid disclosure of Confidential Information hereunder. The parties
will consult with each other on the provisions of this Agreement to be redacted
in any filings made by the parties with the Securities and Exchange Commission
or as otherwise required by law.

     13.4 Publications. Each party to this Agreement recognizes that the
publication of papers containing results of and other information regarding
development of the Licensed Product in the Field, including oral presentations
and abstracts, may be beneficial to both parties provided such publications are
subject to reasonable controls to protect Confidential Information. In
particular, it is the intent of the parties to maintain the confidentiality of
any Confidential Information included in any United States or foreign
application until such United States or foreign patent application has been
published. Accordingly, the other party shall have the right and obligation to
review and approve any paper proposed for publication by the other party,
including oral presentations and abstracts. Before any such paper is submitted
for publication, the party proposing publication shall deliver a complete copy
to the other party at least 45 days prior to submitting the paper to a
publisher. The other party shall review any such paper and give its comments to
the publishing party within 30 days of the delivery of such paper to the other
party. With respect to oral presentation materials and abstracts, the other
party shall make reasonable efforts to expedite review of such materials and
abstracts, and shall return such items as soon as practicable to the publishing
party with appropriate comments, if any, but in no event later than 30 days from
the date of delivery to the other party. The publishing party shall comply with
the other party's request to delete references to the non-publishing party's
Confidential Information in any such paper. Notwithstanding anything to the
contrary in this Agreement, neither party shall have the right to publish in any
form any Confidential Information of the other party without such other party's
prior written consent. With respect to publications of papers containing results
and other information regarding development of the Licensed Product in the Other
Indications, Pierre Fabre agrees to communicate to Cypress for its information a
copy of such documents prior to their publications.

market disclosure. Each party agrees to review each press release within 48
hours after receiving the press release from the other party. In addition,
following the initial joint press release announcing this Agreement, either
party shall be free to disclose, without the other party's prior written
consent, the existence of this Agreement, the identity of the other party and
those terms of the Agreement which have already been publicly disclosed in

established by this Agreement, is solely that of independent contractors. This
Agreement does not create any partnership, joint venture or similar business
relationship between the parties. Neither party is a legal representative of the
other party, and neither party can assume or create any obligation,
representation, warranty or guarantee, express or implied, on behalf of the
other party for any purpose whatsoever.

     16.4 Non-Waiver. The failure of a party to insist upon strict performance
of any provision of this Agreement or to exercise any right arising out of this
Agreement shall neither impair that provision or right nor constitute a waiver
of that provision or right, in whole or in part, in that instance or in any
other instance. Any waiver by a party of a particular provision or right shall
be in writing, shall be as to a particular matter and, if applicable, for a
particular period of time and shall be signed by such party.

     16.5 Assignment. Except as expressly provided hereunder, neither this
Agreement nor any rights or obligations hereunder may be assigned or otherwise
transferred by either party without the prior written consent of the other party
(which consent shall not be unreasonably withheld); provided, however, that
either party may assign this Agreement and its rights and obligations hereunder
without the other party's consent in connection with the transfer or sale of all
or substantially all of the business of such party to which this Agreement
relates to a Third Party, whether by merger, sale of stock, sale of assets or
otherwise; provided, that, any assignment made by Cypress shall be made in full
compliance with the provisions of Section 16.6 "Change of Control." In the event
of such transaction, however, intellectual property rights of the acquiring
party to such transaction (if other than one of the parties to this Agreement)
shall not be included in the technology licensed hereunder. The rights and
obligations of the parties under this Agreement shall be binding upon and inure
to the benefit of the successors and permitted assigns of the parties. Any
assignment not in accordance with this Agreement shall be void.

                                      28.

     16.6 Change of Control.

          (a) In the event of a proposed Change in Control (as described below),
Cypress shall provide Pierre Fabre with prior notice of at least 10 business
days of such proposed Change in Control. If Pierre Fabre reasonably determines
that the Third Party acquiror in such Change in Control is not likely to comply
with the terms of this Agreement, Pierre Fabre may request reasonable assurances
from such Third Party acquiror regarding its intent to comply with the terms of
this Agreement by providing written notice of such request within five business
days after the date of the notice from Cypress. If Pierre Fabre does not make
such request within such period, this Agreement will remain in full force and
effect. If Pierre Fabre makes such request within such period, then (a) if such
Third Party acquiror provides Pierre Fabre reasonable assurances in writing of
its intent to comply with the terms of this Agreement no later than the closing
of the Change in Control, then this Agreement will remain in full force and
effect, and (b) if such Third Party acquiror does not provide Pierre Fabre
reasonable assurances in writing of its intent to comply with the terms of this
Agreement by the closing of the Change in Control, then Pierre Fabre may
terminate this Agreement upon written notice to Cypress or its successor in
interest within 30 days after the closing of the Change in Control, with the
consequences of such termination as set forth in Sections 14.3(b)(ii), 14.4 and
14.5.

          (b) As used herein, "Change in Control" means (i) a sale, lease or
other disposition of all or substantially all of the assets of Cypress; (ii) a
merger or consolidation of Cypress in which the holders of Cypress' outstanding
voting stock immediately prior to such transaction own, immediately after such
transaction, securities representing less than 50% of the voting power of
Cypress or Cypress' parent or, if Cypress is not the surviving entity, any other
entity surviving such transaction or the surviving entity's parent; or (iii) an
acquisition by any person, entity or group within the meaning of Section 13(d)
or 14(d) of the Securities and Exchange Act of 1934, as amended (the "Exchange
Act"), or any comparable successor provisions (excluding any employee benefit
plan, or related trust, sponsored or maintained by Cypress or any entity
controlled by Cypress) of the beneficial ownership (within the meaning of Rule
13d-3 promulgated under the Exchange Act, or comparable successor rule) of
securities of Cypress representing at least 50% of the combined voting power
entitled to vote in the election of Directors; provided, however, that clause
(ii) of this Section 16.6(b) shall not apply to a merger effected exclusively
for the purpose of changing the domicile of Cypress or the name of Cypress.

     16.7 No Third Party Beneficiaries. This Agreement is neither expressly nor
impliedly made for the benefit of any party other than those executing it.

     16.8 Severability. If, for any reason, any part of this Agreement is
adjudicated invalid, unenforceable or illegal by a court of competent
jurisdiction, such adjudication shall not affect or impair, in whole or in part,
the validity, enforceability or legality of any remaining portions of this
Agreement. All remaining portions shall remain in full force and effect as if
the original Agreement had been executed without the invalidated, unenforceable
or illegal part.

     16.9 Notices. Any notice to be given under this Agreement must be in
writing and delivered either in person, by any method of mail (postage prepaid)
requiring return receipt, or by overnight courier or facsimile confirmed
thereafter by any of the foregoing, to the party to be

                                      29.

notified at its address(es) given below, or at any address such party has
previously designated by prior written notice to the other. Notice shall be
deemed sufficiently given for all purposes upon the earlier of: (a) the date of
actual receipt; (b) if mailed, three calendar days after the date of postmark;
or (c) if delivered by overnight courier or by facsimile, the next business day
the overnight courier regularly makes deliveries or on the day after the
facsimile has been sent.

unrest, accident, destruction or other casualty, any lack or failure of
transportation facilities, any lack or failure of supply of raw materials, any
strike or labor disturbance, or any other event similar to those enumerated
above. Such excuse from liability shall be effective only to the extent and
duration of the event(s) causing the failure or delay in performance and
provided that the party has not caused such event(s) to occur. Notice of a
party's failure or delay in performance due to force majeure must be given to
the other party within 10 calendar days after its occurrence. All delivery dates
under this Agreement that have been affected by force majeure shall be tolled
for the duration of such force majeure. In no event shall any party be required
to prevent or settle any labor disturbance or dispute. Notwithstanding the
foregoing, should the event(s) of force majeure suffered by a party extend
beyond a three month period, the other party may then terminate this Agreement
by written notice to the non-performing party, with the consequences of such
termination as set forth in Sections 14.3, 14.4 and 14.5.

     16.11 Legal Fees. If any party to this Agreement resorts to any legal
action or arbitration in connection with this Agreement, the prevailing party

                      STANDARD OPERATING PROCEDURE FOR USE
                                     BETWEEN
                       CYPRESS AND PIERRE FABRE MEDICAMENT
                            FOR TRANSMISSION OF DATA

--------------------------------------------------------------------------------

The aim of this standard operating procedure is to allow the best possible
conditions for the transmission of data concerning tolerance and safety of the
Licensed Product, between CYPRESS and PIERRE FABRE MEDICAMENT.

However, the procedure detailed herein does not take into account the decisions
that might arise consequent to any exchange of information which could involve
other structures than pharmacovigilance services.

This procedure only concerns the modalities of transmission directly between the
pharmacovigilance services of both parties, whether in the context of clinical
trials or in the context of drug marketing. It is not the aim of this procedure
to describe the modalities for collecting or transmitting information inside the
firms which are already defined by domestic operating procedures.

I - DEFINITIONS

1.1. Adverse Event ("AE")

An Adverse Event is any undesirable event temporarily or otherwise occurring to
a subject, associated with administration of the Licensed Product regardless if
the event is considered causally related to the use of the Product.

In case of clinical trials, no distinction will be made between the Licensed
Product and a comparative drug for reporting purposes.

Adverse Events may occur in the use of the Licensed Product in clinical studies,
in professional practice, from overdoses (whether accidental or intentional)
from abuse or from withdrawal of the Licensed Product or otherwise.

1.2. Serious Adverse Event ("SAE")

A Serious Adverse Event includes, but is not limited to, any Adverse Event that
is fatal, life threatening, disabling or requires in-patient hospitalization or
prolongation of hospitalization. In addition, congenital anomaly, occurrence of
malignancy and the result of an overdose, are considered Serious Adverse Events.

1.3. Unexpected Adverse Event ("UAE")

                                      39.

<PAGE>

An Unexpected Adverse Event is an Adverse Event that is not listed in the
current investigator's brochure in the IND phase and/or in the current
international data sheet in the NDA phase.

In the NDA phase, Unexpected Adverse Events also include:

       . an increase in frequency of an event already listed,
       . an increase in severity or pathological progression of an event already
         listed,
       . a more precise description of events already listed.

1.4. Adverse Drug Reaction ("ADR")

An Adverse Drug Reaction is an Adverse Event suspected or confirmed to be caused
by the Licensed Product. Injuries by overdosing, abuse, dependence and/or
interactions with other medicinal products should also be considered as Adverse
Drug Reactions.

A Serious Adverse Drug Reaction is an Adverse Drug Reaction that fulfils the
definition of seriousness as provided in Paragraph 1.2. hereof.

1.5. Imputability

Imputability is the evaluation of the degree of direct relation between an
Adverse Event and the Licensed Product. When a treatment combines several
medicinal products, the analysis of imputability first concerns the treatment as
a whole and then each of its components separately.

II -   TRANSMISSION IN THE CONTEXT OF CLINICAL TRIALS (WHATEVER THE PHASE: I,
       II, III, IV)

2.1. Assessment of tolerability

Clinical trials are usually designed to assess the benefit / risk ratio or the
tolerance of a drug. All Adverse Events will be recorded on case report forms
provided for the study. Assessment of causal relationship will be based on
pooled data from several studies.

However, the Serious Adverse Events imply a particular transmission and the
investigator will be requested to assess the causal relationship to the Product
being tested for each Serious Adverse Event.

2.2. Modalities of transmission of Serious Adverse Events

       2.2.1. From study monitor to pharmacovigilance services

       Each party must have comprehensive internal Standard Operating
       Procedures, defining the internal circulation of data concerning
       pharmacovigilance.

<PAGE>

       The dictionary used is the most recently revised edition of the WHO
       terminology dictionary.

       2.2.2. Between the pharmacovigilance services

       As soon as received, the pharmacovigilance service sends the S.A.E. data
       to the other party via fax transmission using the reporting form defined
       in Appendix I, page 1 or a similar document. This fax transmission is
       performed according to the conditions of transmission referred to in
       Paragraph 2.2.1. above, to guarantee confidentiality.

       Subsequently, the pharmacovigilance service will upon receipt, send
       additional information, using the reporting form defined in Appendix I,
       page 2 or a similar document.

       Upon request of either party, the pharmacovigilance service shall also
       send all available additional data obtained, if any, on the type of
       Adverse Event described in the above mentioned documents.

       All Serious Adverse Events regarding the Licensed Product, regardless of
       relationship, will be transmitted between CYPRESS and PIERRE FABRE
       MEDICAMENT.

III -  TRANSMISSION IN THE CONTEXT OF DRUG MARKETING (EXCEPT PHASE IV TRIALS)

Procedures concerning Adverse Drug Reactions whether spontaneously notified by
prescribers to either party, transmitted by official pharmacovigilance services
or described in literature.

Adverse Drug Reactions, whatever the imputability might be, are subject to
transmission.

3.1. Frequency in transmitting Adverse Drug Reactions

ADRs are transmitted in a semestrial summary report that can coincide with the
dates of transmission determined by the respective national Authorities, all in
accordance with the regulatory provisions in force in the respective countries
concerned.

All information between the parties will be sent in English, using the standard
reporting forms.

On the basis of this report, each party, upon request, may receive communication
of available additional data, if any, from the pharmacovigilance services which
issued the summary report.

Whenever necessary, the summary report can be issued or exchanged on a more
frequent basis than annually, or even lead to technical meetings, subject to
agreement between the parties.

As far as published Adverse Drug Reactions are concerned, the transmission is
performed by sending the publication to the respective party by the other
pharmacovigilance service, as soon as it is aware of the A.D.R. publication.

<PAGE>

3.2. Transmission of Serious Adverse Drug Reactions

Serious Adverse Drug Reactions, whatever the imputability might be, are subject
to the same specific transmission procedure described in Paragraph 2.2.2. for
Serious Adverse Events in clinical trials.

However, the primary transmission is made by telefax using the reporting form
defined in Appendix II (Suspect Adverse Reaction Report) - or a similar
document.

At any time, Serious Adverse Drug Reactions may lead to a technical meeting of
the concerned pharmacovigilance services.

         1.1  Trademarks; Ownership of Trademarks. Pierre Fabre and Cypress
shall mutually agree upon one or more trademarks under which Cypress, its
Affiliates and sub-licensees will exclusively market the Licensed Products (the
"Trademarks") in the Licensed Territory. Pierre Fabre shall own and shall retain
the ownership of the entire right, title and interest in and to the Trademarks.

         1.2  Registration of the Trademarks. While Cypress is marketing the
Licensed Products using the Trademarks, Pierre Fabre shall, at its own cost and
expense, file in the Licensed Territory and endeavor in good faith to obtain the
registration of the applicable Trademarks in the Licensed Territory, and when
registered, thereafter maintain the applicable Trademarks in the Licensed
Territory at its own expense. Pierre Fabre shall keep Cypress informed of
progress with regard to the prosecution, maintenance, enforcement and defense of
the Trademarks by providing Cypress copies of official actions, amendments and
responses with respect to such prosecution. In the event that Pierre Fabre
desires to abandon any of the Trademarks in the Licensed Territory, Pierre Fabre
shall provide reasonable prior written notice to Cypress of such intention to
abandon and provide Cypress an opportunity to discuss with Pierre Fabre the
possibility of assuming responsibility for such Trademarks. If Cypress assumes
responsibility for any Trademarks, such Trademarks shall be assigned to Cypress
and shall no longer be included in the Trademarks subject to this Agreement.

         1.3  License to Trademarks. Pierre Fabre hereby grants to Cypress an
exclusive license, with the right to sublicense to a sub-licensee of rights
under the License Agreement, to identify the Licensed Product to be packaged and
sold by Cypress under the License Agreement

                                       1.

<PAGE>

under the Trademarks in the Licensed Territory and to promote, market, sell and
use such Licensed Products in the Licensed Territory under the Trademarks during
the Term.

         1.4  Quality Control. The nature and quality of the Licensed Products
advertised or sold by Cypress on which the Trademarks appear shall conform to
quality standards and Licensed Product specifications for packaging and quality
control of the Licensed Product mutually agreed between Pierre Fabre and
Cypress. Cypress agrees to cooperate with Pierre Fabre to enable Pierre Fabre to
control the nature and quality of the use of the Trademarks such that Pierre
Fabre may verify that the use of the Trademarks is consistent with the agreed
quality standards and Licensed Product specifications. From time to time and
upon request by Pierre Fabre, Cypress shall provide Pierre Fabre with samples of
the Licensed Product.

         1.5  Rights as Between Parties. Cypress acknowledges, as between the
Parties, the exclusive rights, title and interest of Pierre Fabre in and to the
Trademarks and will not do or cause to be done any act or thing contesting or,
in any way, impairing or tending to impair any part of said right, title and
interest for the Term and after its expiry. Cypress will not make any
representations or take any actions, which may be taken to indicate that it has
any right title or interest in or to the ownership or use of the Trademarks
except under the terms of this Agreement and acknowledges that nothing contained
in this Agreement shall give Cypress any right, title or interest in or to the
Trademarks save as granted hereby.

         1.6  Infringement.

              (a)   Infringement by Third Parties. Pierre Fabre and Cypress
shall promptly notify the other in writing of any alleged or threatened
infringement or any challenge to the validity of the Trademarks or any challenge
to Pierre Fabre's ownership of or Cypress' and/or its sub-licensees' right to
use the Trademarks of which they become aware. Both parties shall use their best
efforts in cooperating with each other to terminate such infringement without
litigation. Pierre Fabre shall have the sole right to bring and control any
action or proceeding with respect to infringement of any of the Trademarks at
its own expense and by counsel of its own choice. With respect to infringement
of any of the Trademarks in the Licensed Territory, if Pierre Fabre fails to
bring an action or proceeding within (a) 60 days following the notice of alleged
infringement or (b) 10 days before the time limit, if any, set forth in the
appropriate laws and regulations for the filing of such actions, whichever comes
first, Cypress shall have the right to bring and control any such action at its
own expense and by counsel of its own choice, and Pierre Fabre shall have the
right, at its own expense, to be represented in any such action by counsel of
its own choice. In the event a party brings an infringement action, the other
party shall cooperate fully, including if required to bring such action, the
furnishing of a power of attorney. Neither party shall have the right to settle
any infringement litigation under this Section 1.6(a) relating to the Trademarks
without the prior written consent of the other party. Except as otherwise agreed
to by the parties as part of a cost-sharing arrangement, any recovery realized
as a result of such litigation, after reimbursement of any litigation expenses
of Pierre Fabre and Cypress, shall be retained by the party that brought and
controlled such litigation.

              (b)   Infringement of Third Party Rights. Each party shall
promptly notify the other in writing of any allegation by a Third Party that the
activity of either of the parties pursuant to this Agreement infringes or may
infringe the intellectual property rights of such

                                       2.

<PAGE>

Third Party. Pierre Fabre shall have the first right to control any defense
of any such claim alleging that the use of the Trademarks in relation with the
Licensed Product infringes any Third Party rights in the Licensed Territory, at
its own expense and by counsel of its own choice, and Cypress shall have the
right, at its own expense, to be represented in any such action by counsel of
its own choice. If Pierre Fabre fails to proceed in a timely fashion with regard
to such defense, Cypress shall have the right to control any such defense of
such claim at its own expense and by counsel of its own choice, and Pierre Fabre
shall have the right, at its own expense, to be represented in any such action
by counsel of its own choice. Neither party shall have the right to settle any
trademark infringement litigation under this Section 1.6(b) relating to the use
of the Trademarks in the Licensed Territory without the consent of such other
party.

         1.7  Goodwill. Any accretion of goodwill derived by Cypress, its
Affiliates or sub-licensees from the use of the Trademarks shall accrue to
Pierre Fabre and Pierre Fabre may call for a confirmatory assignment thereof.

         1.8  Registered User.

              (a)   Where required, Pierre Fabre shall make applications to the
Registrar of Trademarks (or equivalent) for the registration of Cypress as a
registered user of the Trademarks in respect of each registration of the
Trademark and Cypress shall co-operate with Pierre Fabre in making such
applications.

              (b)   Cypress shall execute further documents, depose to or swear
or procure the deposing to or swearing of such declarations or oaths and do any
act or thing and provide any information or evidence which may be necessary or
desirable for registering and maintaining registration of Cypress as a
registered user.

         1.9  Reasonable Assistance. Cypress will, upon request, supply Pierre
Fabre or its authorized representative with any information as to its use of the
Trademarks which Pierre Fabre may require and will render any assistance
reasonably required by Pierre Fabre in securing and maintaining the
registration(s) of the Trademarks in the Licensed Territory.

         1.10 Royalty Payments.

              (a)   Earned Royalties. In consideration of the right and license
hereby granted, during the Term, Cypress shall pay Pierre Fabre a royalty of
[...***...] of Net Sales of the Licensed Product made by Cypress, its Affiliates
and sub-licensees in the Licensed Territory.

              (b)   Payments- Records - Audits.

                    (i)   Payment; Reports. Royalty payments and reports for the
sale of the Licensed Products shall be calculated and reported for each calendar
quarter. All payments due to Pierre Fabre shall be paid within [...***...] of
the end of each calendar quarter, unless otherwise specifically provided herein.
Each payment of royalties shall be accompanied by a report of Net Sales of the
Licensed Products in sufficient detail to permit confirmation of the accuracy of
the payment made, including, without limitation and on a country-by-country
basis, the number of the Licensed Products sold, the gross sales and Net Sales
of the Licensed

                                               *Confidential Treatment Requested

                                       3.

Products, the royalty payment calculated in United States dollars, the
method used to calculate the royalty payment and the exchange rates used.

                    (ii)  Exchange Rate; Manner and Place of Payment. All
payments hereunder due and payable by Cypress to Pierre Fabre shall be payable
in Euros. With respect to each quarter, whenever conversion of payments from any
foreign currency shall be required, such conversion shall be made at the rate of
exchange reported in The Wall Street Journal, Western Edition, on the last
business day of the applicable quarter. All payments owed under this Agreement
shall be made by wire transfer to a bank and account designated in writing by
the party entitled to receive such payment, unless otherwise specified in
writing by such party.

                    (iii) Withholding of Taxes. Pierre Fabre will pay any and
all taxes levied on account of such payment. If any taxes are required to be
withheld by Cypress, Cypress will (a) deduct such taxes from the remitting
payment, (b) timely pay the taxes to the proper taxing authority, and (c) send
proof of payment to Pierre Fabre and certify its receipt by the taxing authority
within 60 days following such payment.

                    (iv)  Records and Audits. During the Term and for a period
of five years thereafter, Cypress shall keep complete and accurate records
pertaining to gross sales and Net Sales of the Licensed Product, including the
expenses incurred by Cypress, in sufficient detail to permit the other party to
confirm the accuracy of all payments due hereunder. Pierre Fabre shall have the
right to cause an independent, certified public accountant reasonably acceptable
to Cypress to audit such records to confirm Net Sales and payments for a period
covering not more than the preceding three years. Such audits may be exercised
during normal business hours upon reasonable prior written notice to Cypress;
provided, however, such audits may not be performed more than one time in each
calendar year. Prompt adjustments shall be made by the parties to reflect the
results of such audit. Pierre Fabre shall bear the full cost of such audit
unless such audit discloses a variance of more than 5% from the amount of the
Net Sales or payments due under this Agreement. In such case, Cypress shall bear
the full cost of such audit. In the event of underpayment, Cypress shall
promptly remit to Pierre Fabre the amount of any underpayment.

                    (v)   Prohibited Payments. Notwithstanding any other
provision of this Agreement, if Cypress is prevented from paying any payments
due hereunder by virtue of the statutes, laws, codes or governmental regulations
of the country from which the payment is to be made, then such payments may be
paid by depositing funds in the currency in which accrued to Pierre Fabre
account in a bank acceptable to Cypress in the country whose currency is
involved.

         1.11 Ownership of the Trademarks. Pierre Fabre has the right to grant
Cypress the exclusive license granted under Section 1.3 hereof and such license
does not conflict with or violate the terms of any agreement between Pierre
Fabre and any Third Party.

         1.12 Term and Termination.

              (a)   Term. The term of this Agreement (the "Term") shall commence
on the Effective Date and shall remain in full force and effect for so long as
Cypress, its Affiliates and

                                       4.

<PAGE>

sub-licensees continue to sell the Licensed Product under any of the Trademarks
in the Licensed Territory unless earlier terminated pursuant to Section 1.12(b)
or 1.12(c).

              (b)   Termination for Cause. Termination by either party. A party
shall have the right to terminate this Agreement upon 90 days' prior written
notice to the other upon the occurrence of any of the following:

                    (i)   Upon or after the bankruptcy, insolvency, dissolution
or winding up of the other party (other than a dissolution or winding up for the
purpose of reconstruction or amalgamation); or if a party admits in writing its
inability to pay its debts as they become due, or

                    (ii)  Upon or after the breach of any material provision of
this Agreement by the other party if the breaching party has not cured such
breach within the 90-day period following written notice of termination by the
non-breaching party.

              (c)   Termination of the License Agreement. In the event the
License Agreement is earlier terminated prior to the expiration of the License
Term, for any reason other than by Cypress pursuant to Section 14.2(a)(i) or
(ii) thereof, then this Agreement shall be terminated without any further act or
notice and Cypress shall no longer have any right to use the Trademarks in the
Licensed Territory. In the event that the License Agreement is terminated by
Pierre Fabre pursuant to Section 14.2(a)(i) of the License Agreement and this
Agreement is terminated pursuant to Section 1.12(b)(i), then any sublicenses
granted under Section 1.3 shall survive the termination of the Term and become
direct licenses from Pierre Fabre under this Agreement.

              (d)   Effect of Termination; Surviving Obligations.

                    (i)   Upon expiration or termination of the Term, all rights
and obligations under this Agreement shall automatically terminate except as
provided in Section 1.12(c).

                    (ii)  Expiration or termination of this Agreement shall not
relieve the parties of any obligation accruing prior to such expiration or
termination.

                    (iii) Within 30 days following the expiration or termination
of this Agreement, each party shall deliver to the other party any and all
Confidential Information of the other party in its possession.

                    (iv)  The license granted under this Agreement will be
deemed a license of rights to intellectual property for purposes of Section
365(n) of the U.S. Bankruptcy Code and a licensee under the Agreement will
retain and may fully exercise all of its rights and elections under the US
Bankruptcy Code.

              (e)   Exercise of Right to Terminate. The use by either party
hereto of a termination right provided for under this Agreement shall not give
rise to the payment of damages or any other form of compensation or relief to
the other party with respect thereto.

                                       5.

<PAGE>

              (f)   Damages; Relief. Termination of this Agreement shall not
preclude either party from claiming any other damages, compensation or relief
that it may be entitled to upon such termination.

2.       Miscellaneous.

         2.1  Governing Law and Venue. This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of New York
excluding its conflicts of law principles. Each party irrevocably submits to the
jurisdiction and venue of New York and any such court in any such action or
proceeding and irrevocably waives any objection thereto.

         2.2  Entire Agreement; Modification. This Agreement is both a final
expression of the parties' agreement and a complete and exclusive statement with
respect to all of its terms. This Agreement supersedes all prior and
contemporaneous agreements and communications, whether oral, written or
otherwise, concerning any and all matters contained herein. No rights or
licenses with respect to any intellectual property of either party are granted
or deemed granted hereunder or in connection herewith, other than those rights
expressly granted in this Agreement. No trade customs, courses of dealing or
courses of performance by the parties shall be relevant to modify, supplement or
explain any term(s) used in this Agreement. This Agreement may not be modified
or supplemented by any purchase order, change order, acknowledgment, order
acceptance, standard terms of sale, invoice or the like. This Agreement may only
be modified or supplemented in a writing expressly stated for such purpose and
signed by the parties to this Agreement.

         2.3  Relationship between the Parties. The parties' relationship, as
established by this Agreement, is solely that of independent contractors. This
Agreement does not create any partnership, joint venture or similar business
relationship between the parties. Neither party is a legal representative of the
other party, and neither party can assume or create any obligation,
representation, warranty or guarantee, express or implied, on behalf of the
other party for any purpose whatsoever.

         2.4  Non-Waiver. The failure of a party to insist upon strict
performance of any provision of this Agreement or to exercise any right arising
out of this Agreement shall neither impair that provision or right nor
constitute a waiver of that provision or right, in whole or in part, in that
instance or in any other instance. Any waiver by a party of a particular
provision or right shall be in writing, shall be as to a particular matter and,
if applicable, for a particular period of time and shall be signed by such
party.

         2.5  Assignment. Except as expressly provided hereunder, neither this
Agreement nor any rights or obligations hereunder may be assigned or otherwise
transferred by either party without the prior written consent of the other party
(which consent shall not be unreasonably withheld); provided, however, that
either party may assign this Agreement and its rights and obligations hereunder
without the other party's consent in connection with the transfer or sale of all
or substantially all of the business of such party to which this Agreement
relates to a Third Party, whether by merger, sale of stock, sale of assets or
otherwise In the event of such transaction, however, intellectual property
rights of the acquiring party to such transaction (if

                                       6.

<PAGE>

other than one of the parties to this Agreement) shall not be included in the
technology licensed hereunder. The rights and obligations of the parties under
this Agreement shall be binding upon and inure to the benefit of the successors
and permitted assigns of the parties. Any assignment not in accordance with this
Agreement shall be void.

         2.6  No Third Party Beneficiaries. This Agreement is neither expressly
nor impliedly made for the benefit of any party other than those executing it.

         2.7  Severability. If, for any reason, any part of this Agreement is
adjudicated invalid, unenforceable or illegal by a court of competent
jurisdiction, such adjudication shall not affect or impair, in whole or in part,
the validity, enforceability or legality of any remaining portions of this
Agreement. All remaining portions shall remain in full force and effect as if
the original Agreement had been executed without the invalidated, unenforceable
or illegal part.

         2.8  Notices. Any notice to be given under this Agreement must be in
writing and delivered pursuant to the License Agreement.

         2.9  Force Majeure. Except for the obligation to make payment when due,
each party shall be excused from liability for the failure or delay in
performance of any obligation under this Agreement by reason of any event beyond
such party's reasonable control including but not limited to Acts of God, fire,
flood, explosion, earthquake, or other natural forces, war, civil unrest,
accident, destruction or other casualty, any lack or failure of transportation
facilities, any lack or failure of supply of raw materials, any strike or labor
disturbance, or any other event similar to those enumerated above. Such excuse
from liability shall be effective only to the extent and duration of the
event(s) causing the failure or delay in performance and provided that the party
has not caused such event(s) to occur. Notice of a party's failure or delay in
performance due to force majeure must be given to the other party within 10
calendar days after its occurrence. All delivery dates under this Agreement that
have been affected by force majeure shall be tolled for the duration of such
force majeure. In no event shall any party be required to prevent or settle any
labor disturbance or dispute. Notwithstanding the foregoing, should the event(s)
of force majeure suffered by a party extend beyond a three month period, the
other party may then terminate this Agreement by written notice to the
non-performing party, with the consequences of such termination as set forth in
Sections 1.12(c), (d), (e) and (f).

         2.10 Legal Fees. If any party to this Agreement resorts to any legal
action or arbitration in connection with this Agreement, the prevailing party
shall be entitled to recover reasonable fees of attorneys and other
professionals in addition to all court costs and arbitrator's fees which that
party may incur as a result.
