                 in either case at the royalty rate set forth in Section
                 5.1(a) that would be applicable had such Gross Profits been
                 made by ESI, and provided that in either case, ESI shall remain

independent certified accountant (subject to obligations of confidentiality)
appointed by the other party and reasonably acceptable to ESI or CIMA (as
applicable), at the other party's expense, to examine such books and records at
all reasonable times for the sole purpose of (i) verifying ESI's or CIMA's (as
applicable) reports and accounting submitted to the other party hereunder and
(ii) determining the correctness of payments. In the event of any underpayment

         5.7 CURRENCY BLOCKAGE Where payments are due hereunder for sales of
Product in a country where, by reason of currency regulations or taxes of any
kind, it is impossible or illegal for ESI to transfer payments to CIMA in that
country, such payments

                                                                              17

on account of the receipt of payments under this Agreement which are required to
be withheld shall be paid by ESI on behalf of CIMA and shall be paid to the
proper taxing authority. Proof of payment shall be secured, if available, and
sent to CIMA by ESI as evidence of such payment in such form as required by the

reasonable measures to assist CIMA in obtaining credit for such taxes against
CIMA's United States tax liabilities.

                                                                              18
<PAGE>   20

         (g) the execution, delivery and performance by such party of this
Agreement and its compliance with the terms and provisions hereof does not and

further represents and warrants to ESI that:

         (a) As of the Effective Date, the CIMA Patents are existing and, to the

         (b) It has the full right, power and authority to grant all of the
right, title and interest in the licenses granted under Article II hereof;

Product, or the CIMA Patents, or CIMA Technical Information, with respect to
which ESI has been granted a license or other rights hereunder in the Territory,
provided that CIMA has granted, and may in the future grant, licenses to Third
Parties under such CIMA Patents and CIMA Technical Information which licenses do
not conflict with the rights granted to ESI under this Agreement;

                                                                              19
<PAGE>   21

         (d) It is the sole and exclusive owner of the CIMA Patents and

Information;

         (g) During the Term of this Agreement it will use Commercially
Reasonable Efforts not to diminish the rights under the CIMA Patents and
Technical Information licensed to ESI hereunder, by not committing or permitting
any actions or omissions which would cause the breach of any agreements between
itself and Third Parties which provide for intellectual property rights
applicable to the development, manufacture, use or sale of Product, that it will
provide ESI promptly with notice of any such alleged breach, and that as

                                                                              20

                                 INDEMNIFICATION

         7.1 INDEMNIFICATION BY ESI Except as provided in Section 9.3, ESI shall
indemnify, defend and hold harmless CIMA and its Affiliates, and each of its and
their respective employees, officers, directors and agents (each a "CIMA
Indemnified Party") from and against any all liability, loss, damage, cost and
expense (including reasonable attorney's fees) (collectively, a "Liability")
which the CIMA Indemnified Party may incur, suffer or be required to pay
resulting from or arising in connection with (i) the breach by ESI of any
representation or warranty contained in this Agreement, or (ii) the manufacture,
promotion, distribution, use, testing, marketing, sale or other disposition of
Product by ESI, its Affiliates or sublicensees. Notwithstanding the foregoing,
ESI shall have no obligation under this Agreement to indemnify, defend or hold
harmless any CIMA Indemnified Party with respect to claims, demands, costs or
judgments which result from either (x) the failure of Product supplied by CIMA
or its Affiliates to comply with the Specifications or the

                                                                              21
<PAGE>   23

applicable Regulatory Approvals or (y) the willful misconduct or negligent acts
or omissions of CIMA, its Affiliates, or any of their respective employees,
officers, directors or agents.

         7.2 INDEMNIFICATION BY CIMA Except as provided in Section 9.3, CIMA
shall indemnify, defend and hold harmless ESI and its Affiliates, and each of
its and their respective employees, officers, directors and agents (each, a "ESI
Indemnified Party") from and against any Liability which the ESI Indemnified
Party may incur, suffer or be required to pay resulting from or arising in
connection with the breach by CIMA of any representation or warranty contained
in this Agreement. Notwithstanding the foregoing, CIMA shall have no obligation
under this Agreement to indemnify, defend, or hold harmless any ESI Indemnified
Party with respect to claims, demands, costs or judgments which result from the
failure of Active Ingredient supplied by ESI or its Affiliates to comply with
the Specifications or the applicable Regulatory Approvals, or from the willful
misconduct or negligent acts or omissions of ESI, its Affiliates, or any of
their respective employees, officers, directors or agents.

         7.3 CONDITIONS TO INDEMNIFICATION The obligations of the indemnifying
party under Sections 7.1 and 7.2 are conditioned upon delivery of written notice
to the indemnifying party of any potential Liability promptly after the
indemnified party becomes aware of such potential Liability, provided, however,
that the failure to give such notice promptly shall not impair a party's rights
to indemnification under this Article VII unless the delay in providing such
notice has a material adverse effect on the ability of the indemnifying party to
defend against such Liability. The indemnifying party shall have the right to
assume the defense of any suit or claim related to the Liability if it has
assumed responsibility for the suit or claim in writing; however, if in the
reasonable judgment of the

                                                                              22
<PAGE>   24

indemnified party, such suit or claim involves an issue or matter which could
have a material adverse effect on the business operations or assets of the
indemnified party, the indemnified party may waive its rights to indemnity under
this Agreement and control the defense or settlement thereof, but in no event
shall any such waiver be construed as a waiver of any rights such party may have
as against any Third Party at law or in equity. If the indemnifying party
defends the suit or claim, the indemnified party may participate in (but not
control) the defense thereof at its sole cost and expense.

         7.4 SETTLEMENTS Neither party may settle a claim of action related to a
Liability without the consent of the other party, if such settlement would
impose any monetary obligation on the other party or require the other party to
submit to an injunction or otherwise limit the other party's rights under this
Agreement. Any payment made by a party to settle any such claim or action shall
be at its own cost and expense except in the event that such payment was made
with the prior written consent of the indemnifying party, in which case such
payment will be subject to the indemnification obligations of the parties as set
forth in this Article VII.

         7.5 INSURANCE Each party further agrees to obtain and maintain, during
the term of this Agreement, Comprehensive General Liability Insurance, including
Products Liability Insurance, with reputable and financially secure insurance
carriers to cover its indemnification obligations under Section 7.1 or 7.2, as
applicable, or, in the case of ESI, self-insurance, in each case with limits of
not less than one million dollars ($1,000,000.00) per occurrence and two million
dollars ($2,000,000.00) in the aggregate.

                                                                              23

                                 CONFIDENTIALITY

         8.1 NONDISCLOSURE During the Term of this Agreement and for a period of
five (5) years thereafter, all proprietary and confidential business, technical,
scientific and/or regulatory information, including Technical Information,
disclosed to the receiving party or its Affiliates (herein collectively, the
(Receiving Party) by the other party or its Affiliates (herein collectively, the
(Disclosing Party) hereunder or under the existing Confidentiality Agreement
between the parties which is marked as confidential at the time of disclosure,
or if disclosed or obtained orally or visually (or otherwise in a non-written
form), was described or summarized in a writing or other tangible form and
identified as confidential and forwarded to the Receiving Party within thirty
(30) days of such disclosure (collectively, Confidential Information), shall be
deemed to be confidential and shall be treated as such by the Receiving Party
and shall not be disclosed, in whole or in part, by the Receiving Party to any
other Person except as expressly set forth herein, and shall be used only for
the purposes of this Agreement. Notwithstanding the foregoing these mutual
obligations of confidentiality shall not apply to any information to the extent
that such information is:

         (i) independently developed by such party as documented by prior
written records outside the scope and not in violation of this Agreement;

         (ii) legally in the public domain at the time of its receipt or
thereafter legally becomes part of the public domain through no fault of the
recipient;

         (iii) received without an obligation of confidentiality from a Third
Party having the right to disclose such information;

         (iv) released from the restrictions of this Article VIII by the express
written consent of the Disclosing Party;

                                                                              24
<PAGE>   26

         (v) as may be required for securing Regulatory Approval, or as may be
required to be disclosed to an Agency or as otherwise required by a court order
or any law or regulation (including, as may be required in connection with any
filings made with the Securities and Exchange Commission or by the disclosure
policies of a major stock exchange in the Territory); provided, however, that at
the other party's request, the disclosing party shall request that the relevant
legal or regulatory authority, or major stock exchange, treat as confidential
any Confidential Information of either party included in any such disclosure and
generally use diligent efforts to seek confidential treatment where available.

         8.2 SCOPE OF CONFIDENTIALITY CIMA and ESI agree to limit the disclosure
of any Technical Information and other Confidential Information received
hereunder to such Affiliates, officers and employees as are necessary to carry
out the provisions of this Agreement and who are likewise bound by provisions
equivalent to this Article VIII, except that, with CIMA's written consent, which
shall not be unreasonably withheld or delayed, ESI may disclose Confidential
Information of CIMA to consultants, to distributors, and to actual or potential
sublicencees and subdistributors, provided that they are likewise bound by
confidentiality provisions similar to, or more stringent than, those set forth
in this Article VIII. The parties shall take reasonable measures to assure that
no unauthorized use or disclosure is made by Persons to whom access to such
Confidential Information is granted. Unauthorized use or disclosure by any
person who has been given access to Confidential Information by a Receiving
Party hereunder shall be deemed to be unauthorized use or disclosure by such
Receiving Party, and the Receiving Party shall be responsible to the Disclosing
Party hereunder.

                                                                              25

                                   ARTICLE IX

               TECHNOLOGY AND DATA OWNERSHIP RIGHTS; INFRINGEMENT

         9.1 OWNERSHIP OF DATA AND TECHNICAL INFORMATION

             (a) CIMA shall solely own all formulation, system design, chemistry
manufacturing and control (CMC) and manufacturing process data and documents
that arise out of the development program ("CIMA Data"), and ESI shall execute
such documents and take such actions as are necessary to implement the
foregoing. ESI shall solely own all clinical data and documents arising from the
development program for Product funded by ESI ("ESI Data"), and CIMA shall
execute such documents and take such actions as are necessary to implement the
foregoing. ESI agrees to disclose to CIMA, on an on-going basis, in writing, all
ESI Data, provided that CIMA shall not be permitted to use such ESI Data except
for internal research purposes, and further provided that ESI shall not disclose
such ESI Data to any Third Party.

             (b) Inventorship of any inventions acquired or developed in
connection with the development program shall be determined by reference to
United States patent laws pertaining to inventorship. Accordingly, (i) if an
invention is made in connection with the development program by one (1) or more
employees or consultants of each party, it shall be deemed to be a "Joint
Invention". If one or more claims included in an issued Patent or pending patent
application which is filed in a patent office in the Territory claim such Joint
Invention following rules shall govern ownership of such Patent or patent
application: (a) Joint Inventions which relate to specifically Loratadine and/or
administration of Loratadine shall be the sole property of ESI, (b) Joint
Inventions which relate to rapidly-dissolving dosage forms shall be the sole
property of CIMA but shall be included in the CIMA Patents and shall be subject
to the license granted hereunder; and

                                                                              26
<PAGE>   28

             (c) any other Joint Inventions shall be jointly owned by CIMA and
ESI as Joint Patent Rights hereunder. If an invention is made in connection with
the development program solely by an employee or consultant of a party, it shall
be solely owned by such party, and any Patent filed claiming such solely owned
invention shall also be solely owned by such party. Each party shall require its
employees and consultants to disclose to it any inventions relating to the
Product in writing promptly after conception, and each party shall, subsequent
to any such disclosures to it by its employees or consultants, promptly disclose
such inventions to the other party. Each party shall ensure that its employees
and consultants shall assign his/her interest in such invention(s) to his/her
respective party employer, as the case may be, and such rights shall therefore
vest in the respective party employer to whom the inventor assigns his/her
rights. CIMA shall use Commercially Reasonable Efforts to obtain and maintain
CIMA Patents for the CIMA DuraSolv(TM) (OraSolv(R)) technologies in the Major
Countries. The parties shall mutually agree upon how and where to file and
prosecute any Joint Patent Rights, the maintenance of any ensuing Joint Patent
Rights covering such Joint Inventions, and how to license, enforce, defend and
protect any such Joint Patent Rights and how to share the costs relating
thereto.

         9.2 INFRINGEMENT

             (a) Each party shall promptly report in writing to the other party
during the term of this Agreement any known infringement or suspected
infringement of any of the CIMA Patents in the Territory by manufacture, use or
sale of a Product on a commercial scale in derogation of the rights granted to
ESI hereunder (hereinafter, a "Related Infringement") of which it becomes aware,
and shall provide the other party with all available evidence supporting said
infringement or suspected infringement.

                                                                              27
<PAGE>   29

             (b) Except as provided in paragraph (d) below, CIMA shall have the
right to initiate an infringement or other appropriate suit anywhere in the
Territory against any Third Party who at any time has infringed, or is suspected
of infringing, any of the CIMA Patents. CIMA shall give ESI sufficient advance
notice of its intent to file any suit on account of a Related Infringement and
the reasons therefor, and shall provide ESI with an opportunity to make
suggestions and comments regarding such suit. CIMA shall keep ESI promptly
informed, and shall from time to time consult with ESI regarding the status of
any such suit on account of a Related Infringement and shall provide ESI with
copies of all documents filed in, and all written communications relating to,
such suit.

             (c) CIMA shall have the sole and exclusive right to select counsel
for any suit referred to in subsection (b) above and shall, except as provided
below, pay all expenses of the suit, including without limitation attorneys'
fees and court costs. ESI, in its sole discretion, may elect, within 60 days
after the commencement of such litigation on account of a Related Infringement,
to contribute to the costs incurred by CIMA in connection with such litigation
and, if it so elects, any damages, royalties, settlement fees or other
consideration received by CIMA as a result of such litigation shall be shared by
CIMA and ESI pro rata based on their respective sharing of the costs of such
litigation provided that such pro rata share shall not exceed fifty percent
(50%) unless CIMA has consented to a higher share in writing. In the event that
ESI elects not to contribute to the costs of such litigation, CIMA shall be
entitled to retain any damages, royalties, settlement fees or other
consideration for infringement resulting therefrom. If necessary, ESI shall join
as a party to the suit but shall be under no obligation to participate except to
the extent that such participation is required as the result of being a named
party to the suit. ESI shall offer

                                                                              28
<PAGE>   30

reasonable assistance to CIMA therewith at no charge to CIMA except for
reimbursement of reasonable out-of-pocket expenses incurred in rendering such
assistance. ESI shall have the right to participate and be represented in any
such suit by its own counsel at its own expense. CIMA shall not settle any such
suit on terms which grant any license to any other party in derogation of the
rights granted to ESI hereunder without obtaining the prior written consent of
ESI, which consent shall not be unreasonably withheld.

             (d) In the event that CIMA elects not to initiate an infringement
or other appropriate suit pursuant to subsection (b) above on account of a
Related Infringement after reasonable efforts to abate such Related Infringement
without litigation have failed, but in no event later than ninety (90) days
after ESI's notice to CIMA under Section 9.3(a), CIMA shall promptly advise ESI
of its intent not to initiate such a suit, ESI shall have the right, at the
expense of ESI, of initiating an infringement or other appropriate suit against
the party or parties committing such Related Infringement. In exercising its
rights pursuant to this subsection (d), ESI have the sole and exclusive right to
select counsel and shall, except as provided below, pay all expenses of the suit
including without limitation attorneys' fees and court costs. CIMA, in its sole
discretion, may elect, within 60 days after the commencement of such litigation,
to contribute to the costs incurred by ESI in connection with such litigation,
and, if it so elects, any damages royalties, settlement fees or other
consideration received by ESI as a result of such litigation shall be shared by
ESI and CIMA pro rata based on their respective sharing of the costs of such
litigation provided that such pro rata share shall not exceed fifty percent
(50%) unless ESI has consented to a higher share in writing.

         In the event that CIMA elects not to contribute to the costs of such
litigation, ESI shall be entitled to retain any damages, royalties, settlement
fees or other consideration for

                                                                              29

infringement resulting therefrom. If necessary, CIMA shall join as a party to
the suit but shall be under no obligation to participate except to the extent
that such participation is required as a result of being named a party to the
suit. At ESI's request, CIMA shall offer reasonable assistance to ESI in
connection therewith at no charge to ESI except for reimbursement of reasonable
out-of-pocket expenses incurred in rendering such assistance. CIMA shall have
the right to participate and be represented in any such suit by its own counsel
at its own expense.

         9.3 CLAIMED INFRINGEMENT

             (a) In the event that a Third Party at any time provides written
notice of a claim to, or brings an action, suit or proceeding against, either
party or any of their respective Affiliates, claiming infringement of its patent
rights, based upon an assertion or claim arising out of the filing of an ANDA
for Product, or the use, manufacture, distribution or sale of Product, such
party shall promptly notify the other party of the claim or the commencement of
such action, suit or proceeding, enclosing a copy of the claim and/or all papers
served.

             (b) If a Third Party at any time brings an action, suit or
proceeding against ESI and/or CIMA and/or their Affiliates, claiming
infringement of its patent rights, based upon ESI's filing of an ANDA for
Product in the Territory, ESI shall be responsible for the defense, costs and
expenses, including attorney's fees, thereof. ESI shall have the right to use
counsel of its own choice and shall control the defense of any such action, suit
or proceeding. If CIMA desires to have additional counsel of its own choice
participate in the defense, CIMA shall be solely responsible for the costs and
expenses of its counsel. ESI shall have the authority to settle any such action,
suit or proceeding with the prior written consent of CIMA, such consent not to
be unreasonably withheld or delayed. If ESI receives

                                                                              30
<PAGE>   32

any payment(s) as part of the settlement of any such threatened or actual
action, suit or proceeding, then after deduction of ESI's costs and expenses,
including attorney's fees, the balance (if any) of such payment(s) shall be
split eighty percent (80%) to ESI and twenty percent (20%) to CIMA.

             (c) If a Third Party at any time brings an action, suit or
proceeding against ESI and/or its Affiliates, claiming infringement of its
patent rights, based upon an assertion or claim arising out of the use,
importation, distribution, offer for sale or sale of Product in the Territory on
account of the CIMA rapid dissolve technology used to manufacture Product, the
parties shall share equally responsibility for and any and all costs and
expenses associated with such legal actions including, without limitation,
damages, settlement payments, attorneys' fees and court costs. Each party shall
offer reasonable assistance to the other party in connection therewith at no
charge to the other party except for reimbursement of reasonable out-of-pocket
expenses incurred in rendering such assistance.

             (d) This Section 9.3 states the entire responsibility of CIMA in
the case of any claimed infringement or violation of any Third Party's patent
rights.

provision of this Agreement, shall continue in full force and effect, on a
country-by-country basis, until the

                                                                              31

other longer period of time if mutually agreed; provided that if the defaulting
party initiates steps within the sixty (60) day notice period to remedy or cure
the breach, unless the parties mutually agree otherwise, such termination shall

trademarks (the "MARKS") as applicable on the package, internal leaflet and
promotional material of the Product by printing "Produced with CIMA DuraSolv(TM)
(OraSolv(R)) technology" or word DuraSolv(TM) (OraSolv(R)). For this purpose,
CIMA grants to ESI and its Affiliates a non-exclusive license to use CIMA's
DuraSolv(TM) and OraSolv(R) trademarks during the Term. Prior to its printing,
ESI (or an Affiliate) shall send CIMA a sample of the packaging, internal
leaflet and related promotional material for CIMA's prior approval of ESI's use
of the MARKS.

         12.2 TRADEMARK OWNERSHIP AND USE

              a. ESI recognizes CIMA's exclusive ownership of and title in and
to the MARKS, and shall not at any time do or permit to be done any act or thing
which would in any way impair the rights of CIMA in and to the MARKS or in any
trademark registration

                                                                              35
<PAGE>   37

application therefor, and shall not at any time claim any right of interest in
or to the MARKS or the aforesaid trademark application therefor.

              b. ESI agrees that during the term of the Agreement and after its
termination, however occurring, that ESI shall not:

                 (i) use the MARKS or any other mark confusingly similar thereto
              in connection with any goods not covered by this Agreement which
              would be likely to cause confusion between the parties; or

                 (ii) apply for or seek registration anywhere in the world, at
              any time, for the MARKS or any other mark confusingly similar
              thereto; or

                 (iii) commit or do any act which might prejudice or adversely
              affect the validity of the MARKS or CIMA's ownership thereof or
              dilute or diminish the value of the MARKS to CIMA.

              c. ESI shall use the MARKS only in a proper trademark sense and
shall identify the MARKS as a registered trademark of CIMA by including use of
the registered trademark symbol (R) or the symbol (TM) in association with the
MARKS as specified by CIMA.

              d. ESI agrees that all goodwill resulting from its use of the
MARKS shall inure to the exclusive benefit of CIMA.

              e. ESI shall assist CIMA in obtaining or maintaining registrations
for the MARKS by supplying specimens, other proofs of use and other information
or documents reasonably necessary to obtain or maintain registration of the
MARKS in all jurisdictions within the Territory.

              12.3 QUALITY CONTROL ESI agrees that, to the extent the Product is
manufactured by a party other than CIMA pursuant to this Agreement, the Product
shall be manufactured

                                                                              36
<PAGE>   38

in accordance with the Specifications. CIMA shall have the right to inspect the
Products sold in connection with the MARKS so that CIMA can determine that the
Products meet the Specifications. If the quality of any Products is determined
not to meet the Specifications, then ESI shall not use any of the MARKS in
connection with such Products and ESI shall, at its option, either (i) destroy
such Products or (ii) repackage such Products to eliminate use of the MARKS.

control which it could not have avoided by the exercise of reasonable diligence,

                                 ADVERSE EVENTS

                     ADVERSE EXPERIENCE REPORTING PROCEDURES

         The parties hereby agree that the following terms will govern
disclosures of each party to the other with respect to adverse event reporting
relating to Product as clinically tested or marketed by or on behalf of either
party.

1.       DEFINITIONS.

         1.1 ADVERSE EXPERIENCE OR EVENT (AE): An AE is defined by ESI as any
             untoward, undesired, or unplanned event in the form of signs,
             symptoms, disease, or laboratory or physiological observations
             occurring in a human being in a temporal relationship to use of an
             ESI product regardless of casual relationship. This includes:

             -  any clinically significant worsening of a pre-existing
                condition;

             -  an AE occurring from overdose (i.e., a dose higher than that
                prescribed by a health care professional for clinical reasons)
                of an ESI product, whether accidental or intentional;

             -  an AE occurring from abuse (i.e., use for non-clinical reasons)
                of an ESI product;

             -  an AE that has been associated with the discontinuation of the
                use of an ESI product;

             -  any failure of expected pharmacological action (for spontaneous
                reports).

             If there is any doubt whether the information constitutes an AE,
             the information will be treated as an AE.

         1.2 SERIOUS AE: A serious AE is defined by ESI as an AE occurring at
             any dose that: results in death; is life-threatening (see below);
             requires inpatient hospitalization or prolongation of an existing
             hospitalization; results in a persistent or significant disability
             or incapacity (see below); results in cancer; results in a
             congenital anomaly or birth defect. Additionally, IMPORTANT MEDICAL
             EVENTS that may not result in death, be life-threatening, or
             require hospitalization may be considered a serious AE when, based
             upon appropriate medical judgment, they may jeopardize the patient
             or subject and may require medical or surgical intervention to
             prevent one of the outcomes listed in this definition. Examples of
             such medical events include allergic bronchospasm requiring
             intensive treatment in an emergency room or at home; blood
             dyscrasias or convulsions that do not result in hospitalization; or
             the development of drug dependency or abuse.

                                       1
<PAGE>   51
             1.2.1 Life-threatening refers to immediate risk of death as the
                   event occurred. A life-threatening experience does not
                   include an experience that, had it occurred in a more severe
                   form, might have caused death but as it actually occurred did
                   not create an immediate risk of death. For example, hepatitis
                   that resolved without evidence of hepatic failure would not
                   be considered life-threatening even though hepatitis of a
                   more severe nature can be fatal. Similarly, an allergic
                   reaction resulting in angioedema of the face would not be
                   life-threatening, even though angioedema of the larynx,
                   allergic bronchospasm, or anaphylaxis can be fatal.

             1.2.2 Disability is defined as a substantial disruption in a
                   person's ability to conduct normal life functions.

             1.2.3 For studies, all pregnancies and all overdoses will be
                   reported to GSSE in the same time frame as serious AEs.

             1.2.4 A serious AE obtained from tests in laboratory animals
                   includes any experience suggesting a significant risk for
                   human subjects, including any findings of mutagenicity,
                   teratogenicity, or carcinogenicity.

             1.2.5 If there is any doubt whether the information constitutes a
                   serious AE, the information will be treated as a serious AE.

         1.3 NON-SERIOUS AE: is any AE which does not meet the criteria for a
             serious AE.

         1.4 UNEXPECTED AE: An unexpected AE is one that is not listed in the
             current product labeling. The current product labeling is either
             the package insert (for marketed ESI products) or the current
             investigator's brochure (for investigational ESI products). An
             unexpected AE includes any event that may be symptomatically and
             pathophysiologically related to an event listed in the labeling,
             but differs from the labeled event because of greater severity or
             specificity. For example, hepatic necrosis would be unexpected (by
             virtue of greater severity) if the product labeling referred only
             to elevated hepatic enzymes or hepatitis. Similarly, cerebral
             thromboembolism and cerebral vasculitis would be unexpected (by
             virtue of greater specificity) if the labeling only listed cerebral
             vascular accidents.

         1.5 PRODUCT (DRUG, VACCINE, BIOLOGICAL, DEVICE)-RELATED: For the
             purposes of regulatory reporting for investigational products, an
             AE will be considered "product-related" (i.e., drug-related,
             vaccine-related, etc.) for studies if either the investigator, the
             Medical Monitor, the CR&D Clinical Project Team Medical Monitor (or
             designee), OR the Local Monitor (if applicable) assesses the AE(s)
             as possibly, probably, or definitely related.

                                       2

<PAGE>   52

                  1.   An AE will be considered "not product-related" for
                       studies if the investigator AND the medical monitor(s)
                       AND the local monitor (if applicable) assess the AE(s) as
                       probably not related or definitely not related, or
                       "relationship remote."

                  2.   Whenever the investigator's or monitor's assessment is
                       unknown or unclear, the AE(s) will be treated as
                       product-related for the purposes of reporting to
                       regulatory authorities.

         1.6 PROTOCOL-RELATED: AEs from studies that are not product-related may
             nevertheless be considered by the investigator OR the medical
             monitor(s) OR the local monitor (if applicable) to be
             protocol-related. For purposes of reporting to GSSE and regulatory
             authorities, these will be reported in the same manner as
             product-related events.

         1.7 ANDA HOLDER is defined as: An "Applicant" for regulatory approval
             of a Product in any regulatory jurisdiction, including a holder of
             a foreign equivalent thereto.

                  the other Party) must be communicated by telephone, telefax or

                  Holder, ("Holder") within forty-eight (48) hours of receipt of
                  the information. Written confirmation of the Serious AE
                  received by such Party should be sent to the other Party
                  and/or the Holder as soon as it becomes available, but in any
                  event within forty-eight (48) hours of initial report of the
                  Serious AE by such Party.

         b.       Both Parties shall exchange Medwatch and/or CIOMs forms and
                  other health authority reports within forty-eight (48) hours
                  of submission to any Regulatory Authority.

         c.       All initial reports and follow-up information received for all
                  Non-Serious AEs for marketed Product which become known to a
                  Party (other than from disclosure by or on behalf of the other
                  Party) must be communicated in writing, by telefax or
                  electronically to the other Party within ten (10) days, on
                  Medwatch or CIOMs forms (where possible).

         d.       Each Party shall coordinate and cooperate with the other
                  whenever practicable to prepare a single written report
                  regarding all Serious and/or Non-Serious AEs, provided,
                  however, that neither Party shall be obligated to delay
                  reporting of any AE in violation of applicable law or
                  regulations regarding the reporting of AEs.

             humans;

         b.  Each Party will give the other Party a report via a print-out or
             computer disk of all AEs reported to it and its Affiliates relating
             to the Product or Active Ingredient within the last year, within
             thirty (30) days of receipt of a request from the other Party but
             not more often than four (4) times a year;

         c.  If either Party wishes access to AE Reports of the other Party
             relating to the Product or Active Ingredient, upon request of that
             Party, the other Party shall make available its AE records relating
             to the Product or Active Ingredient (including computer disks) for
             viewing and copying by the other Party. The Parties may discuss the
             transfer of AE Reports by computer disk.

             shall continue as long as either Party and/or its Affiliates or

forecast received by CIMA for such ninety (90) day period, then CIMA shall use
Commercially Reasonable Efforts, but shall not be obligated, to ship that
portion of the excess over one hundred fifty percent (150%).

progress, obsolete inventory disposal and overhead; but this obligation shall
not cover capital costs.

         2.7 PAYMENT TERMS (a) CIMA shall provide an invoice with each delivery
of Product to ESI specifying the amount that shall be due to CIMA (the
Estimated Amount), which shall be based on CIMA's good faith estimate of Direct
Manufacturing Cost per unit of Product. Within thirty (30) days after receipt of
an invoice from CIMA, ESI shall pay to CIMA the Estimated Amount.
<PAGE>   10
         (b) Within thirty (30) days of the end of each calendar half year, CIMA
shall provide to ESI a report in writing setting forth in reasonable detail the
calculation of the total payments due based on CIMA's actual Direct
Manufacturing Cost of Product (the Actual Amount), for the calendar half year
for which such payment applies.

         (c) In the event the Actual Amount for Product purchased by ESI in a
calendar half year is less than the Estimated Amount for that calendar half
year, then CIMA shall pay to ESI such difference amount with CIMA's report for
that calendar half year. In the event the Actual Amount for Product purchased by
ESI in a calendar half year is greater than the Estimated Amount for that
calendar half year, then ESI shall pay to CIMA such greater amount within
fourteen (14) days of ESI's receipt of CIMA's invoice for such amount with
regard to ESI's purchases of Product in that calendar half year.

         2.8 QUALITY ASSURANCE

         (a) Prior to the shipment of Product to ESI, CIMA shall test
representative samples of each of the batch(es) to be shipped in accordance with
validated, approved methods of analysis defined in the Specifications. CIMA
shall provide ESI with a Certificate of Analysis for each batch of Product
shipped to ESI stating that the Product so shipped conforms to the
Specifications. The Certificate of Analysis shall be in a format agreed upon by
the parties.

<PAGE>   11

         (b) CIMA shall retain production samples and batch records from each
batch of Product for the longer of (i) five (5) years after the manufacture of
each such batch of Product or (ii) the time period required under GMP. Upon
request, CIMA shall provide ESI's Quality Control Department with production
samples of Product and/or copies of completed Batch records.

         (c) Master batch process documentation will be prepared and approved by
CIMA as per its normal procedures. The parties agree that deviations from master
batch process documentation may be necessary from time to time. Such deviations
shall be discussed with ESI before any proposed shipment of Product. Individual
batch process documentation shall be photocopied from the approval master and
issued for each batch as per CIMA's routine system. Original batch records will
be filed securely by CIMA. CIMA will perform all in-process control tests
demanded by the approved batch process.

         (d) ESI shall have the right to test Product to verify compliance with
Specifications and applicable Regulatory Approvals and CIMA shall supply ESI
with its testing procedures. ESI may, by written notice provided to CIMA within
sixty (60) days of ESI's receipt of a shipment of Product, reject all or part of
such shipment of Product if, based upon the testing of such Product conducted
under this Section 2.8, such Product does not comply with the Specifications or
applicable Regulatory Approvals. If ESI fails to notify CIMA within such sixty
(60) day period, that it is rejecting such Product, ESI shall be deemed to have
accepted such Product.
<PAGE>   12

         (e) If CIMA, after good faith consultation with ESI, disputes any
finding by ESI that Product does not comply with the Specifications or
applicable Regulatory Approvals, samples of such Product shall be forwarded to a
Third Party jointly selected by ESI and CIMA for analysis, which analysis shall
be performed in compliance with applicable regulatory requirements. The findings
of such Third Party regarding whether Product complies with the Specifications
and the applicable Regulatory Approvals shall be binding upon the parties for
purposes of this Section 2.8. The cost of such analysis by such Third Party
shall be borne by the party whose findings differed from those generated by such
Third Party.

         (f) If as determined in accordance with this Section 2.8, a shipment of
Product does not conform to the Specifications or applicable Regulatory
Approvals, CIMA shall replace such shipment free of charge with a substitute
shipment which meets such Specifications and applicable Regulatory Approvals
according to the following time frame: If the Product is in inventory then
conforming Product will be shipped so as to arrive as soon as practicable. If
the Product is not in inventory, CIMA will take all reasonable steps to ensure
expeditious manufacture of conforming Product which will be shipped on the next
shipping day after completion of manufacture so as to arrive as soon as possible
thereafter. In the event that testing at ESI indicates that Product does not
conform with Specifications or applicable Regulatory Approvals: (i) ESI shall
immediately notify CIMA (ii) ESI and CIMA shall mutually agree on an

<PAGE>   13
investigation program to determine the cause of the discrepancy and the outcome
of this investigation shall be used to determine disposition of the batch; (iii)
where appropriate, given the timetable for the agreed upon investigation
program, CIMA shall take all reasonable steps to ensure expeditious manufacture
and shipment of conforming Product; and (iv) shipment of such replacement
Product shall take place the next shipping day following completion of
analytical work to demonstrate conformance with Specifications and applicable
Regulatory Approvals. Shipment shall be by the quickest agreed route. At CIMA's
expense and at ESI's sole option: the non-conforming shipment shall be (i)
returned to CIMA; or (ii) disposed of by ESI, upon final determination in
accordance with this Section 2.8 that it does not meet the Specifications or
applicable Regulatory Approvals. If the non-conformity in the Product is due to
a non-conformity of the Active Ingredient with the Specifications at the time of
its delivery to CIMA, then the Replacement Product manufactured and shipped by
CIMA under this Section 2.8 and the disposal of the non-conforming shipment
shall be at the sole cost and expense of ESI.

         2.9 ESI MANUFACTURE RIGHTS DURING THE TERM

         Upon ESI's written request, made at any time after first ANDA
submission, CIMA shall grant to ESI the exclusive, irrevocable, transferable
right, and shall use Commercially Reasonable Efforts to transfer to ESI the
manufacturing know-how used by CIMA that is reasonably necessary to enable ESI
to manufacture Product. If ESI exercises this right, except as provided below,
ESI shall pay CIMA (a) a [***CONFIDENTIAL TREATMENT REQUESTED, PORTION OMITTED
FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION.***]

<PAGE>   14

technical transfer fee upon successful completion of the transfer process
(defined as manufacture of validation batches of Product meeting the
Specifications), and (b) out of pocket expenses incurred by CIMA directly
related to the technical assistance needed to facilitate the transfer process.
If ESI exercises this right due to the inability of CIMA to meet ESI firm orders
for Product, for any reason other than a condition of force majeure that lasts
less than 60 days, then ESI shall pay CIMA only out-of-pocket expenses incurred
by CIMA directly related to the technical assistance needed to facilitate the
transfer process.

         2.10 NOTIFICATION OF INSPECTIONS Each party agrees to notify the other
within two (2) business days of its receipt of notification of any inquiries,
notifications, or inspection activity by any Agency, regulatory authority or
other authority in regard to or affecting Product. The recipient party shall
provide a reasonable description to the other party of any such governmental
inquiries, notifications or inspections promptly (but in no event later than
five (5) calendar days) after notification of completion of such visit or
inquiry. The recipient party shall furnish to the other party, (i) within two
(2) business days after receipt any report or correspondence issued by the
Agency or regulatory authority in connection with such visit or inquiry,
including but not limited to, any FDA Form 483, Establishment Inspection Reports
or warning letters and (ii) at the same time it provides to any Agency or
regulatory authority, copies of any and all documents, responses or explanations
relating to items set forth above, in each case purged only of trade secrets of
the recipient that are unrelated to the obligations under this Agreement or are
unrelated to Product. In the event such governmental agency or
<PAGE>   15
authority requests or requires any action to be taken to address any citations,
the recipient agrees, after consultation with the other party, to take such
action as necessary to address such citations, and agrees to cooperate with the
other party with respect to any such citation and/or action taken with respect
thereto.

         2.11 INSPECTION BY ESI CIMA shall permit ESI (at its own expense) to
visit, during normal business hours and with reasonable advance notice CIMA's
manufacturing facility(ies) and warehouse, subject to the confidentiality
provisions of this Agreement, for the purposes of (a) observing the manufacture,
packaging, testing and warehousing of Product and to inspect for compliance with
GMP's, applicable regulatory requirements, the requirements of any applicable
Regulatory Approvals, and environmental monitoring, (b) solving technical or
quality problems, (c) examining the premises, equipment, procedures and
personnel used when producing, testing or controlling Product and (d) all books
and records relating to (a), (b) or (c). CIMA representatives shall be entitled
to accompany ESI representatives on any such inspection.

         2.12 ENVIRONMENTAL AND OTHER LAWS AND REGULATIONS

         (a) In carrying out its obligations under this Agreement, CIMA shall
comply with all applicable environmental, health and safety laws (current or as
amended or added, collectively "Laws"), and shall be solely responsible for
determining how to comply with same. CIMA represents and warrants that it has
the appropriate skills, personnel, equipment, permits or approvals necessary to
perform its services under this Agreement in compliance with all applicable
Laws.

<PAGE>   16

         (b) CIMA shall notify ESI, in writing, no later than one (1) business
day after the event, of any circumstances, including the receipt of any notice,
warning, citation, finding, report or service of process, relating to compliance
with the Laws, or the occurrence of any release, spill, upset or discharge of
"Hazardous Active Ingredients" as defined by the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended, which relates to
CIMA's ability to manufacture or supply Product. ESI reserves the right to
conduct an environmental inspection of CIMA's facility(ies), during normal
business hours and with reasonable advance notice, for the purpose of
determining compliance with this Section 2.12(b), no more frequently than once
per year during the term hereof and under conditions of confidentiality as
provided under Article VIII. Upon CIMA's request, ESI shall share the results of
any environmental inspection with CIMA. Such inspection, if it occurs, does not
relieve CIMA of its sole obligation to comply with the Laws and does not
constitute a waiver of any right otherwise available to ESI.

         2.13 SPECIFICATIONS AMENDMENTS The Specifications shall be amended or
supplemented to comply with GMPs and to comply with any applicable Agency
directive and may also be amended or supplemented (including, without
limitation, for the purpose of incorporating improvements) from time to time. In
the event CIMA intends to amend the Specifications, ESI shall receive prompt
advance notice of any such amendments. No such amendment shall be filed with any
applicable Agency or otherwise become effective without the prior written mutual
approval of ESI and CIMA. In the event that after the parties have initially
agreed upon the Specifications, ESI
<PAGE>   17
requests that the Specifications be amended, CIMA shall receive prompt advance
notice of any such amendment for the purpose of determining what, if any, impact
the proposed amendment would have on the manufacture of Product for ESI
hereunder and ESI shall reimburse CIMA for the actual costs incurred by CIMA
(provided that such costs are approved in writing by ESI prior to being incurred
by CIMA) because such amendment requires changes to be made in the processes,
equipment, testing procedures, or components used to manufacture Product for ESI
hereunder. Such costs may include, without limitation, validation of new
processes, equipment and facilities, development of testing methods and start-up
costs. Any costs incurred by CIMA in implementing an amendment of the
Specifications under this Section shall not be included in CIMA's Direct
Manufacturing Cost.

         2.14 APPROVAL FOR MANUFACTURING CHANGES; THIRD PARTY MANUFACTURING CIMA
agrees that no changes will be made to any materials, equipment or methods of
production or testing which are specified in the Specifications or any
Regulatory Approval by any Agency for Product without ESI's prior written
approval, which approval shall not be unreasonably withheld. Under no
circumstances will CIMA contract out all or any part of the manufacturing of
Product to a Third Party without prior written approval from ESI.

         2.15 PERMITTED SUBCONTRACTORS CIMA shall ensure that the permitted
contract manufacturers for the manufacture of Product have sufficient knowledge
and expertise to carry out the manufacture of Product and other subcontracted
responsibilities. In addition CIMA shall ensure that (i) each such contract
manufacturer shall be in

<PAGE>   18

compliance with GMPs and shall be under the inspection of all relevant Agencies
and audited to be in compliance therewith, and (ii) ESI will have the right to
inspect and audit each such subcontractor's facilities and records as provided
in Section 2.11 hereof.

                                   ARTICLE III

                                ACTIVE INGREDIENT

         3.1 SUPPLY OF ACTIVE INGREDIENT

             (a) ESI agrees to supply CIMA, at no charge, all Active Ingredient
                 CIMA requires for the manufacture of Product under this
                 Agreement and CIMA agrees to use all and only, Active
                 Ingredient supplied by ESI exclusively in the manufacture of
                 Product.

             (b) As of the time of delivery to CIMA, all Active Ingredient will
                 conform to the Specifications.

             (c) CIMA shall procure all ingredients other than the Active
                 Ingredient used in the manufacture of Product, including
                 excipients, inactive ingredients, imprinting materials,
                 packaging and labeling materials unless otherwise mutually
                 agreed to by the parties.

             (d) CIMA agrees to notify ESI in writing of its requirements for
                 Active Ingredient in a timely manner so as to assure the timely
                 filling of ESI's purchase orders for Product. In the event that
                 ESI fails to have supplied CIMA with sufficient quantities of
                 conforming Active Ingredient at least sixty days prior to the
                 due date for delivery of a

<PAGE>   19

                 Product order, CIMA will be relieved of its obligation to
                 timely fill ESI's purchase orders for such Product to the
                 extent prevented by ESI's failure to have Active Ingredient
                 timely delivered.

             (e) Upon receipt of Active Ingredient, CIMA shall promptly, and in
                 no event later than thirty (30) business days following
                 receipt, sample and analyze the same to assure that it complies
                 with the applicable Specifications. CIMA agrees to provide ESI
                 with the results of such analysis as soon as reasonably
                 possible, but in no event later than CIMA's manufacture of
                 Product containing such Active Ingredient, and to keep, true,
                 accurate and complete records of all such sampling and
                 analyses, which records shall at all reasonable times be
                 available for examination, audit and copying by ESI and its
                 representatives.

             (f) In the event that any Active Ingredient is determined by CIMA
                 not to be in compliance with applicable Specifications, CIMA
                 shall immediately notify ESI and shall follow all instructions
                 of ESI regarding, and be responsible for, re-analysis,
                 sampling, processing, return, disposal or destruction,
                 including certification of destruction, of such non-conforming
                 Active Ingredient.

             (g) If CIMA and ESI disagree as to whether any Active Ingredient
                 meets the applicable Specifications, the matter will be
                 submitted to an independent testing laboratory, acceptable to
                 both parties, for

<PAGE>   20
                     analysis, which analysis shall be performed in compliance
                     with applicable regulatory requirements. If the Active
                     Ingredient is determined to be non-conforming, ESI will
                     reimburse CIMA for CIMA's out-of-pocket expenses relating
                     to re-analysis, sampling, processing, returns, disposal
                     and/or destruction thereof.

         3.2 USE OF ACTIVE INGREDIENT

                 (a) Title to all Active ingredient supplied to CIMA by ESI
                     shall at all times remain in ESI. CIMA shall clearly mark
                     such Active Ingredient as the property of ESI and keep such
                     Active Ingredient separate and apart from other raw
                     materials.

                 (b) CIMA shall not at any time sell or offer for sale, assign,
                     mortgage, pledge, or allow any lien to be created upon the
                     Active Ingredient provided by ESI or any portion thereof.

                 (c) At the termination of this Agreement, CIMA shall surrender
                     to ESI all Active Ingredient in CIMA's possession.

                 (d) CIMA shall be responsible for all loss or damage, howsoever
                     occasioned, in Active Ingredient at all times it is in the
                     possession of CIMA excepting only reasonable loss
                     necessarily inherent in the manufacturing process. The
                     parties agree that the amount of Active Ingredient loss
                     reasonable to the Product's manufacturing process shall in
                     no event be more than six percent (6%) per batch or more
                     than four percent (4%) per any twelve month production

<PAGE>   21

                     period. CIMA shall permit ESI, during normal business hours
                     and upon reasonable advance written notice, access to all
                     records necessary to determine and verify Active Ingredient
                     loss or damages. CIMA shall reimburse ESI for all costs and
                     expenses (including shipping costs incurred by ESI in
                     replacing Active Ingredient lost or damaged but not Active
                     Ingredient which is determined by on analysis pursuant to
                     Paragraph 5.1(g) not to be in compliance with the
                     Specifications.

                 (e) ESI shall not be liable for any damage, loss or injury
                     directly or indirectly resulting from the storage or
                     handling by CIMA of any Active Ingredient.

harmless ESI and its Affiliates, and each of its and their respective employees,
officers, directors and agents (each, an "ESI Indemnified Party") form and
against any Liability which the ESI Indemnified Party may incur, suffer or be
required to pay resulting from or arising in connection with the breach by CIMA
of any representation or warranty contained in this Agreement. Notwithstanding
the foregoing, CIMA shall have no obligation under this Agreement to indemnify,
defend, or hold harmless any ESI Indemnified Party with respect to claims,
demands, costs of judgments which result from the willful misconduct or
negligent acts or omissions of ESI, its Affiliates, or sublicensees or any of
their respective employees, officers, directors or agents.

         7.3 CONDITIONS TO INDEMNIFICATION The obligations of the indemnifying
party under Sections 7.1 and 7.2 are conditioned upon delivery of written notice
to the indemnifying party of any potential Liability promptly after the
indemnified party

<PAGE>   27
becomes aware of such potential Liability, provided, however, that the failure
to give such notice promptly shall not impair a party's rights to
indemnification under this Article VII unless the delay in providing such notice
has a material adverse effect on the ability of the indemnifying party to defend
against such Liability. The indemnifying party shall have the right to assume
the defense of any suit or claim related to the Liability if it has assumed
responsibility for the suit or claim in writing; however, if in the reasonable
judgment of the indemnified party, such suit or claim involves an issue or
matter which could have a materially adverse effect on the business operations
or assets of the indemnified party, the indemnified party may waive its rights
to indemnity under this Agreement and control the defense or settlement thereof,
but in no event shall any such waiver be construed as a waiver of any
indemnification rights such party may have at law or in equity. If the
indemnifying party defends the suit or claim, the indemnified party may
participate in (but not control) the defense thereof at its sole cost and
expense.

         7.4 SETTLEMENTS Neither party may settle a claim of action related to a
Liability without the consent of the other party, if such settlement would
impose any monetary obligation on the other party or require the other party to
submit to an injunction or otherwise limit the other party's rights under this
Agreement. Any payment made by a party to settle any such claim or action shall
be at its own cost and expense except in the event that such payment was made
with the prior written consent of the indemnifying party, in which case such
payment will be subject to the indemnification obligations of the parties as set
forth in this Article VII.

<PAGE>   28

         7.5 INSURANCE Each party further agrees to obtain and maintain, during
the term of this Agreement, Comprehensive General Liability Insurance, including
Products Liability Insurance, with reputable and financially secure insurance
carriers to cover its indemnification obligations under Section 7.1 or 7.2, as
applicable, or, in the case of ESI, self-insurance, in each case with limits of
not less than five million dollars ($5,000,000.00) per occurrence and ten
million dollars ($10,000,000.00) in the aggregate.

required to be disclosed to an Agency or as otherwise required by a court order
or any law or regulation (including, as may be required in connection with any
filings made with the Securities and Exchange Commission or by the disclosure
policies of a major stock exchange in the Territory); provided, however, that at
the other party's request, the disclosing party shall request that the relevant
legal or regulatory authority, or major stock exchange, treat as confidential
any Confidential Information of either party included in any such disclosure and
generally use diligent efforts to seek confidential treatment where available.

         8.2 SCOPE OF CONFIDENTIALITY

and other Confidential Information received hereunder to such Affiliates,

consultants and distributors as are necessary to carry out the provisions of
this Agreement and who are likewise bound by provisions equivalent to this
Article VIII, except that, ESI may disclose Confidential Information to actual
or potential sublicenses and subdistributors, provided that they are likewise
bound by confidentiality provisions similar to, or more stringent than, those
set forth in this Article VIII. The parties shall take reasonable measures to
assure that no unauthorized use or disclosure is made by Persons to whom access
to such Confidential Information is granted.

                                 ADVERSE EVENTS

                     ADVERSE EXPERIENCE REPORTING PROCEDURES

         The parties hereby agree that the following terms will govern
disclosures of each party to the other with respect to adverse event reporting
relating to Product as clinically tested or marketed by or on behalf of either
party.

1.       DEFINITIONS.

         1.1 ADVERSE EXPERIENCE OR EVENT (AE): An AE is defined by ESI as any
             untoward, undesired, or unplanned event in the form of signs,
             symptoms, disease, or laboratory or physiological observations
             occurring in a human being in a temporal relationship to use of a
             ESI product regardless of causal relationship. This includes:

             -  any clinically significant worsening of a pre-existing
                condition;

             -  an AE occurring from overdose (i.e., a dose higher than that
                prescribed by a health care professional for clinical reasons)
                of a ESI product, whether accidental or intentional;

             -  an AE occurring from abuse (i.e., use for non-clinical reasons)
                of a ESI product;

             -  an AE that has been associated with the discontinuation of the
                use of a ESI product;

             -  any failure of expected pharmacological action (for spontaneous
                reports).

             If there is any doubt whether the information constitutes an AE,
             the information will be treated as an AE.

         1.2 SERIOUS AE: A serious AE is defined by ESI as an AE occurring at
             any dose that: results in death; is life-threatening (see below);
             requires inpatient hospitalization or prolongation of an existing
             hospitalization; results in a persistent or significant disability
             or incapacity (see below); results in cancer; results in a
             congenital anomaly or birth defect. Additionally, IMPORTANT MEDICAL
             EVENTS that may not result in death, be life-threatening, or
             require hospitalization may be considered a serious AE when, based
             upon appropriate medical judgment, they may jeopardize the patient
             or subject and may require medical or surgical intervention to
             prevent one of the outcomes listed in this definition. Examples of
             such medical events

<PAGE>   39

             include allergic bronchospasm requiring intensive treatment in an
             emergency room or at home; blood dyscrasias or convulsions that do
             not result in hospitalization; or the development of drug
             dependency or abuse.

             1.2.1 Life-threatening refers to immediate risk of death as the
                   event occurred. A life-threatening experience does not
                   include an experience that, had it occurred in a more severe
                   form, might have caused death but as it actually occurred did
                   not create an immediate risk of death. For example, hepatitis
                   that resolved without evidence of hepatic failure would not
                   be considered life-threatening even though hepatitis of a
                   more severe nature can be fatal. Similarly, an allergic
                   reaction resulting in angioedema of the face would not be
                   life-threatening, even though angioedema of the larynx,
                   allergic bronchospasm, or anaphylaxis can be fatal.

             1.2.2 Disability is defined as a substantial disruption in a
                   person's ability to conduct normal life functions.

             1.2.3 For studies, all pregnancies and all overdoses will be
                   reported to GSSE in the same time frame as serious AEs.

             1.2.4 A serious AE obtained from tests in laboratory animals
                   includes any experience suggesting a significant risk for
                   human subjects, including any findings of mutagenicity,
                   teratogenicity, or carcinogenicity.

             1.2.5 If there is any doubt whether the information constitutes a
                   serious AE, the information will be treated as a serious AE.

         1.3 NON-SERIOUS AE: is any AE which does not meet the criteria for a
             serious AE.

         1.4 UNEXPECTED AE: An unexpected AE is one that is not listed in the
             current product labeling. The current product labeling is either
             the package insert (for marketed ESI products) or the current
             investigator's brochure (for investigational ESI products). An
             unexpected AE includes any event that may be symptomatically and
             pathophysiologically related to an event listed in the labeling,
             but differs from the labeled event because of greater severity or
             specificity. For example, hepatic necrosis would be unexpected (by
             virtue of greater severity) if the product labeling referred only
             to elevated hepatic enzymes or hepatitis. Similarly, cerebral
             thromboembolism and cerebral vasculitis would be unexpected (by
             virtue of greater specificity) if the labeling only listed cerebral
             vascular accidents.

         1.5 PRODUCT (DRUG, VACCINE, BIOLOGICAL, DEVICE)-RELATED: For the
             purposes of regulatory reporting for investigational products, an
             AE will be considered "product-related" (i.e., drug-related,
             vaccine-related, etc.) for studies if either the investigator, the
             Medical Monitor, the CR&D Clinical Project Team Medical

<PAGE>   40

             Monitor (or designee), OR the Local Monitor (if applicable)
             assesses the AE(s) as possibly, probably, or definitely related.

             1. An AE will be considered "not product-related" for studies if
                the investigator AND the medical monitor(s) AND the local
                monitor (if applicable) assess the AE(s) as probably not related
                or definitely not related, or "relationship remote."

             2. Whenever the investigator's or monitor's assessment is unknown
                or unclear, the AE(s) will be treated as product-related for the
                purposes of reporting to regulatory authorities.

         1.6 PROTOCOL-RELATED: AEs from studies that are not product-related may
             nevertheless be considered by the investigator OR the medical
             monitor(s) OR the local monitor (if applicable) to be
             protocol-related. For purposes of reporting to GSSE and regulatory
             authorities, these will be reported in the same manner as
             product-related events.

         1.7 NDA HOLDER is defined as: An "Applicant" as defined in 21 CFR Part
             314.3(b), for regulatory approval of a Product in any regulatory
             jurisdiction, including a holder of a foreign equivalent thereto.

         1.8 IND HOLDER is defined as: A "Sponsor" as defined in 21 CFR Part
             313.1(b) of an investigational new drug in any regulatory
             jurisdiction, including a holder of a foreign equivalent thereto.

         1.9 Capitalized terms not defined in this Exhibit shall have the
             meaning assigned thereto in the Agreement.

2.       With respect to the Product or Active Ingredient, the Parties agree as
         follows:

         a.  All initial reports and any follow-up information (oral or written)
             for any and all Serious AEs as defined above, (other than with
             respect to animal studies) which become known to either Party
             (other than from disclosure by or on behalf of the other Party)
             must be communicated by telephone, telefax or electronically
             directly to the other Party and/or the NDA Holder, IND Holder
             (individually and collectively referred to as "Holders") within
             forty-eight (48) hours of receipt of the information. Written
             confirmation of the Serious AE received by such Party should be
             sent to the other Party and/or the Holders as soon as it becomes
             available, but in any event within forty-eight (48) hours of
             initial report of the Serious AE by such Party.

         b.  Both Parties shall exchange Medwatch and/or CIOMs forms and other
             health

<PAGE>   41

             authority reports within forty-eight (48) hours of submission to
             any Regulatory Authority.

         c.  All initial reports and follow-up information received for all
             Non-Serious AEs for marketed Product which become known to a Party
             (other than from disclosure by or on behalf of the other Party)
             must be communicated in writing, by telefax or electronically to
             the other Party within ten (10) days, on Medwatch or CIOMs forms
             (where possible).

         d.  Each Party shall coordinate and cooperate with the other whenever
             practicable to prepare a single written report regarding all
             Serious and/or Non-Serious AEs, provided, however, that neither
             Party shall be obligated to delay reporting of any AE in violation
             of applicable law or regulations regarding the reporting of AEs.

3.       The Parties further agree that:

         a.  A written report be forwarded to the other Party within forty-eight
             (48) hours of receipt by the Party making the report, for AEs for
             animal studies which suggest a potential significant risk for
             humans;

         b.  Each Party will give the other Party a report via a print-out or
             computer disk of all AEs reported to it and its Affiliates relating
             to the Product or Active Ingredient within the last year, within
             thirty (30) days of receipt of a request from the other Party but
             not more often than four (4) times a year;

         c.  If either Party wishes access to AE Reports of the other Party
             relating to the Product or Active Ingredient, upon request of that
             Party, the other Party shall make available its AE records relating
             to the Product or Active Ingredient (including computer disks) for
             viewing and copying by the other Party. The Parties may discuss the
             transfer of AE Reports by computer disk.

         d.  Disclosure of information hereunder by a Party to the other Party
             shall continue as long as either Party and/or its Affiliates or
             designees continue to clinically test or market Product or Active
             Ingredient.

4.       Each Party shall diligently undertake the following further obligations
         where both Parties are or will be commercializing the Product or Active
         Ingredient pursuant to the Agreement and/or performing clinical trials
         with respect to the Product or Active Ingredient:

         a.  Upon the Effective Date, each Party shall identify individuals who
             shall be responsible for identifying all AE reporting requirements
             in all countries of the Territory as set forth in the Agreement,
             and any amendments thereto;

         b.  To immediately consult with the other Party, with respect to the
             investigation and handling of any Serious AE disclosed to it by the
             other Party or by a third Party and to allow the other Party to
             review the Serious AE and to participate in the follow-up
             investigation;

         c.  To immediately advise the other Party of any Product and/or Active
             Ingredient safety communication received from a health authority
             and consult with the other Party with respect to any Product and/or
             Active Ingredient warning, labeling change or change to an
             investigators' brochure involving safety issues proposed by the
             other Party, including, but not limited to the safety issues agreed
             to by the Parties;

         d.  To diligently handle in a timely manner the follow-up investigation
             and resolution of each AE reported to it;
