increase spending with respect to an existing Development Plan as specifically
provided in this subsection.  As to Excepted Development Matters (i) and (ii)
the status quo shall be maintained (e.g., no updated Development Plan and/or
updated Development Budget shall be established); provided, however, that if
ORTHO desires to accelerate or increase spending in order to increase the size,
increase the number of, or expand the extent of studies with respect to any of
the Collaboration Compound's extant Development Indications and/or extant
Additional Indications contained in the Development Plan, including, but not
limited to, accelerating the Plan to conduct additional clinical trials that
ORTHO reasonably believes might be required by the FDA to obtain FDA approval of
the Collaboration Product for a type II Diabetes  Indication, ORTHO may proceed
to do so at its own expense. If the indication for which such accelerated or
increased spending has taken place is approved by the FDA and the Collaboration
Product is thereafter Commercialized for such indication, ERGO agrees to repay
[*] of any increased spending together with interest at an annual rate of[*].
Such repayment shall be accomplished by deductions from the amount  due to ERGO
from ERGO's share of Operating Profits attributable to such Collaboration
Product, such deductions by ORTHO to commence upon NDA Approval and launch of
the Collaboration Product for the Indication with respect to which spending by
ORTHO was accelerated or increased.  As to Excepted Development Matter item
(iii) in Section 4.02(b), the clinical trial shall be terminated if the Steering
Committee does not reach unanimous decision after prompt consideration.  As to
Excepted Development Matter (iv) in Section 4.02(b), the final decision shall be
made by ERGO, excluding all exceptions provided in Section 4.02(b) for which
ORTHO shall make the final decision.  As to Excepted Development Matter (v) in
Section 4.02(b), ERGO shall make the final decision. Except as provided for
above in this Section 2.04, if the Steering Committee fails to reach agreement
on a matter before it for decision, the matter shall be referred to executive
officers of the Parties pursuant to Section 16.01. The manner described in this
Section 2.04 to resolve disputes regarding Excepted Development Matters shall be
the sole mechanism for resolving such matters under this Agreement.

after the Effective Date (or such later time as may be mutually agreed to by the
Parties), the Parties shall establish the Joint Project Team (hereinafter
referred to as the JPT).  The JPT shall consist of an equal number of
representatives of ERGO and ORTHO to be agreed upon by the Parties from time to
time.  Either Party may designate a substitute for a member unable to be present
at a meeting.  One of the ORTHO members of the JPT, chosen at the sole
discretion of ORTHO, along with one of the ERGO members of the JPT, chosen at
the sole discretion of ERGO, shall serve as co-chairs of the JPT.  Regardless of
the number of representatives from each Party on the JPT, each Party shall have
one vote on any matter on which the JPT makes a decision.  Meetings of the JPT
shall be held at least quarterly and may be called by either Party with not less
than ten (10) business days notice to the other unless such notice is waived,
and meetings shall alternate between the offices of the Parties unless otherwise
agreed.  The JPT may be convened, polled or consulted from time to time by means
of telecommunication or correspondence.  Each Party will disclose to the other
proposed agenda items reasonably in advance of each meeting of the JPT.  Each
Party shall bear its own costs for participation in the JPT, and such costs
shall not be included in Development Expenses.

     SECTION 4.02. Responsibilities of JPT.
                   ----------------------- 

     (a) The JPT will plan and coordinate the Development in the Profit/Loss
Sharing Territory (taking into consideration the need to coordinate Development
Activities in the Profit/Loss Sharing Territory with activities in the Royalty
Bearing Territory) of (i) Collaboration Compounds and Collaboration Products for
Development Indications and/or Additional Indications and (ii) to the extent


                                      17
<PAGE>
 
ORTHO exercises its option(s) under Article IV to include Additional
Indications, if any, in order to obtain Regulatory Approvals in the Profit/Loss
Sharing Territory as set forth in this Article IV.  The JPT, in coordination
with the Lead Development Party, will also prepare the Development Plans and
Development Budgets and submit them to the Steering Committee for approval. In
addition, the JPT will oversee and provide such support with respect to Phase
IIIB Clinical Trials and Phase IV Clinical Trials as may be reasonably be
requested by ORTHO.

     (b) All decisions by the JPT shall be made unanimously, after an open and
informed discussion of the matters as to which decisions are being made.  Except
as provided below, if the JPT is unable to make a unanimous decision as to any
matter involving Development, the decision of ORTHO on such matters will be
final and determinative with respect to all Collaboration Compounds and/or
Collaboration Products so long as such decision does not contradict or modify
the terms of this Agreement.  The following exceptions to an ORTHO decision must
be referred to the Steering Committee for decision, pursuant to Section 2.04;
(i) increasing a Development Budget within the Profit/Loss Sharing Territory;
(ii) altering a Development Plan for the Profit/Loss Sharing Territory in any
material respect, including changing the indications for which a Collaboration
Product is being developed; (iii) terminating any Clinical Trial for the
Profit/Loss Sharing Territory prior to completion in accordance with its
protocol; (iv) conducting the Development of Bromocriptine for the Type II
Diabetes Indication up to the approval of a Drug Approval Application for the
Type II Diabetes Indication, within the Profit/Loss Sharing Territory with the
exception of product labeling, the product label, Advertising, Phase IIIB
Clinical Trials (other than those described in Exhibit E), and Phase IV Clinical
Trials and further Development as required by the FDA as described in Section
4.03; or (v) conducting the Development of Bromocriptine for the Obesity
Indication up to the completion of the Obesity Phase IIA Clinical Trial within
the Profit/Loss Sharing Territory (items (i)-(v) collectively being, hereafter,
"Excepted Development Matters").

     (c) The JPT will have the power to form subcommittees with equal (unless
otherwise agreed) and appropriate representation from ERGO and ORTHO.

     SECTION 4.03. Lead Development Party. The LDP shall be obligated and
                   ----------------------                                
responsible for carrying out Development pursuant to each Development Plan. ERGO
will be the Lead Development Party in the Profit/Loss Sharing Territory with
respect to (i) obtaining FDA Approval and completion of any and all Phase IIIB
Clinical Trials for Bromocriptine as described in Exhibit E, provided, however,
that if the FDA requires further Development that would in the opinion of ORTHO
delay the NDA approval six (6) months or longer past September, 1998, ERGO shall
remain LDP, but, in this instance, the JPT shall make any and all decisions
regarding strategy and work that must be done to obtain NDA approval and any
such work shall be carried out under the direction of ORTHO; (ii) completion of
the Obesity Phase IIA Clinical Trial; and (iii) Developing all other
Collaboration Compounds and/or Collaboration Products through the completion of
any and all Phase IIA Clinical Trials. ORTHO shall be the LDP in the Profit/Loss
Sharing Territory for any and all: (a) Clinical Trials for the Obesity
Indication for Bromocriptine commencing with the start of Phase IIB Clinical
Trials; (b) Clinical Trials for all other Collaboration Products commencing with
Phase IIB Clinical Trials; and (c) Phase IIIB Clinical Trials not recited in
Exhibit E and Phase IV Clinical Trials for Bromocriptine and other Collaboration
Compounds approved for sale in the Profit/Loss Sharing Territory. In connection
with the preceding, the JPT will plan and coordinate, and ORTHO shall be
responsible for obtaining Regulatory Approval for the Obesity Indication for
Bromocriptine and for all other Non-Metabolic Indications for Bromocriptine (to
the extent that they become Additional Indications) and for all other
Collaboration Products for all their respective Development Indications and/or
Additional Indications.  ORTHO shall have the right to act independently of the
JPT in conducting Development Activities and in obtaining Regulatory Approvals
in the Royalty Bearing Territory; provided, however, that ORTHO shall not take
                                  --------                                    
any action in 


                                      18
<PAGE>
 
connection with obtaining Regulatory Approval for a Royalty Bearing Product in
the Royalty Bearing Territory that would materially and adversely affect a
Party's ability to conduct Development Activities pursuant to the Development
Plan.

     Notwithstanding any other provision of this Agreement, ERGO shall be the
LDP with respect to the Phase IIIB Clinical Trials for Bromocriptine as
specifically described in Exhibit E; provided, however, that ERGO shall develop
and finalize the protocols for such trials only after review by and concurrence
of ORTHO.

     SECTION 4.04. Right to Engage Third Parties. In the course of its business,
                   -----------------------------                                
ERGO and ORTHO may use Third Parties to perform certain Development Activities
provided that the use of Third Parties is designated in the Development Plan and
expenses therefor are approved in the Development Budget; provided, however,
                                                          --------          
that both parties shall enter into such Third Party contracts on an arm's-length
basis at reasonable rates customary in the U.S. pharmaceutical industry after
consultation with the non-contracting Party.

     SECTION 4.05. Development Plan and Development Budget.

("Development Plan") and development budget ("Development Budget") that shall
each cover the period through regulatory approvals to market for the Development
Indication and/or Additional Indications, as applicable to such plan or budget.
Each such Development Plan and Development Budget shall (except as provided in
Article V) be prepared by the JPT.  The Development Plan and Development Budget
for the Profit/Loss Sharing Territory shall be agreed to by the JPT and
submitted for approval by the Steering Committee pursuant to Section 2.03.  Any
Development Plan and Development Budget as it relates to the Royalty Bearing
Territory shall be submitted to the JPT and Steering Committee for the sole
purpose of permitting Development Activities in the Royalty Bearing Territory to
be coordinated with Development Activities in the Profit/Loss Sharing Territory.

     (b) ERGO shall provide ORTHO with access (and copies, which may be
partially or wholly electronic form, to the extent requested) to all of the raw
data and reports related to the Development of Bromocriptine for the Type II
Diabetes Indication and the Obesity Indication (such data and report being
collectively referred to herein as the "Bromocriptine Trial Information").  The
Bromocriptine Trial Information shall be accompanied by ERGO's most up-to-date
Development Plan and Development Budget for the Type II Diabetes Indication and
through the end of the Obesity Phase IIA Clinical Trial and will be referred to
as the "Initial Development Plan and Development Budget for Bromocriptine for
the Type II Diabetes Indication and the Obesity Indication," attached hereto as
Exhibit E

     (c) With respect to Development of Eligible Compounds (including Eligible
Compounds that are already Collaboration Compounds) for  an indication that is
not already an extant Development Indication or an extant Additional Indication
and that is accepted for joint Development, an Initial Development Plan and
Initial Development Budget for each such Indication shall be agreed between the
Parties pursuant to provisions set forth in Article V.  Such Initial Development
Plan and Initial Development Budget shall cover the period through regulatory
approvals to market such new Indications.  Each subsequent, updated Development
Plan and each subsequent updated Development Budget shall be prepared and agreed
upon by the JPT in coordination with the Lead Development Party and submitted to
the Steering Committee for review and approval pursuant to Section 2.03.


                                      19

case may be, in the Profit/Loss Sharing Territory, including, but not limited
to, preclinical studies, toxicology, formulation, chemical process development,
clinical studies, regulatory plans and other elements of obtaining Regulatory
Approval in the Profit/Loss Sharing Territory.  The Development Plan shall
include projected timelines for all Development and Regulatory events, a summary
of the estimated Development Expenses and specify Party-specific execution
responsibilities of the program expected during Development through obtaining
Regulatory Approval in the Profit/Loss Sharing Territory for each Collaboration
Compound and/or Collaboration Product for each such proposed Indication, and
shall further include a detailed Development Budget by quarter for all
Development proposed for the following eighteen (18) months.

     (e) An updated Development Plan and an updated Development Budget shall be
prepared annually by the JPT, and submitted by June 30 of each calendar year to
the Steering Committee for review and approval.  Each updated Development Budget
for the Profit/Loss Sharing Territory shall be based on the corresponding
updated Development Plan and shall be prepared in accordance with generally
accepted accounting principles. Within thirty (30) days following such original
submission the Steering Committee shall either approve the updated Development
Plan and updated Development Budget or approve a modified Development Plan and
Development Budget prepared by the Steering Committee consistent with the
objectives for the Collaboration Compound and/or Collaboration Products and the
aims of the collaboration.  If the Steering Committee fails to approve any
change in the Development Budget or a material change in the Development Plan of
the type described in Section 4.02(b)(ii), the last approved Development Budget
and last approved Development Plan shall remain in effect, such that the
Development Budget shall remain at previously approved levels of projected
spending and the Development Plan shall remain in its previously approved form.

     (f) A Development Plan and Budget for the Obesity Indication for
Bromocriptine for Phase IIB and III Clinical Trials shall be agreed to by the
Parties at about the time data from ERGO's Obesity Phase IIA Clinical Trial is
available.  Should the Parties fail to agree on such plan and budget, the joint
Development for the Obesity Indication shall be suspended until such time as the
parties mutually agree to a plan and budget therefor.

     SECTION 4.06. Development Efforts.  ERGO and ORTHO each agree to
                   -------------------

         -------                                                           
pursuant to an approved Development Plan for a Collaboration Product, shall be
shared equally by the Parties in the Profit/Loss Sharing Territory in the manner
as set forth in this Article IV.  Expenses shall  be categorized as Out-of-
Pocket Costs) and Internal Costs (EFT-based).[*]; provided, however, that the
rate determined for a Party for any calendar year cannot be greater than the
rate for such Party for the immediately preceding calendar year, as adjusted
(upwards or downwards) by the percentage change in price inflation over the
preceding twelve (12) month period, determined from the most recently published
change in the All-Urban Consumer Price Index most geographically applicable to
the location of such Party's R&D departments  Calculation of this rate will be
completed and is subject to approval at each annual forecast review.  The
approved rate will be in effect for the approved budget's calendar year.  In
addition, ORTHO agrees to pay to [*]within ten (10) business days after the HSR
Date for pre-effective date Development Expenses incurred by ERGO in calendar
year 1997.  Attached to this Agreement as Exhibit C-1 is a schedule of all pre-
effective date Development Expenses incurred by ERGO in calendar year 1997 to be
reimbursed by ORTHO pursuant to this Agreement.

     (b) Royalty Bearing Territory.  ORTHO shall bear all Development Expenses
         -------------------------                                            
for Collaboration Products that are specifically related to the Development,
manufacture, use and/or sale of a Collaboration Product in the Royalty Bearing
Territory.  As provided in Section 13.01, Information developed by ERGO relating
to the Development of Collaboration Products in the Profit/Loss Sharing
Territory can be used by ORTHO for the Development and regulatory filing of such

(other than reasonable duplicating, postage, and related out of pocket costs).
In addition, as provided in Section 13.01, Information developed by ORTHO
relating to the Development of Collaboration Products in the Royalty Bearing
Territory can be used by ERGO for the purpose of any further Development and
support of regulatory filings of such Collaboration Products in the Profit/Loss
Sharing Territory without further charge (other than reasonable duplicating,
postage, and related out of pocket costs).

     (c) Advanced Payments.   Beginning on January 1, 1998 and continuing
         -----------------                                               
thereafter and based on the current approved Development Budget, the Party
projected to incur less than 50% of the budgeted Development Expenses for a
particular quarter shall make an Advanced Payment or an Adjusted Advanced
Payment to the other Party in an amount such that both Parties, following such
payment, are projected to incur fifty percent (50%) of the budgeted Development
Expense for that quarter.  Such payments shall be made on a quarterly basis for
the current quarter on or before the fifteenth (15th) day of January, April,
July, and October of each year, except that the first quarter 1998 Development
Expenses shall not be made until April 15, 1998.  Within thirty (30) days after
the end of each calendar quarter and fifty (50) days after the end of the fourth
quarter of each full calendar year, the Parties shall report to each other their
Development Expenses.  Within sixty (60) days after the quarter, ORTHO shall
issue a Development Expense Reconciliation Statement, in the form of Exhibit B-
1, showing the Adjusted Advanced Payment for the next quarter.  Advanced
Payments will be adjusted (either increased or decreased) to account for the
Development Expenses actually expended by the Parties in the previous 


                                      22
<PAGE>
 
quarters as shown in the form in Exhibit B-1. The current approved Development
Plan and Development Budget for Bromocriptine for the Type II Diabetes and
Obesity Indications is attached hereto as Exhibit E.

     If the party owing the Advance Payment or Adjusted Advanced Payment fails
to make timely payment as set forth above in this Section 4.08(c), the other
Party shall give such Party 30 days written notice to make such payment.  If
either party fails to make such payment within such 30 day notice period, any
unpaid balance after the 30 days notice period shall bear interest at an annual
rate of [*].  Except for Development Expenses for Bromocriptine for the Obesity
Indication, if ERGO fails to make such Advance Payment or Adjusted Advanced
Payment for two (2) consecutive quarters, the Option available to ORTHO under
Section 8.02(c)(i) and (ii) shall be available to ORTHO as the only remedy for
such failure to pay. For Development Expenses for Bromocriptine for the Obesity
Indication during the period[*], if ERGO fails to make such Advance Payments for
two (2) consecutive quarters, the Option available under Section 8.02(c) shall
be available to ORTHO as the only remedy for such failure to pay.  If ERGO's
failure to pay[*], the following option shall be the only option available to
ORTHO:

          (i) maintain the Profit/Loss Sharing Territory as a Profit/Loss
Sharing Territory except that the ratio for sharing Operating Profits and Losses
shall be [*] until Bromocriptine is approved for an Obesity Indication in which
case it will be [*] and ORTHO shall, subsequent to such failure to make one or
more payments, assume responsibility for [*] of Development Expense to the
extent that ORTHO continues Development  of Bromocriptine for the Obesity
Indication;.  If ORTHO fails to make an Advance Payment, then ORTHO shall be
considered in breach of this Agreement and ERGO may take the appropriate action
against ORTHO as is permitted under the terms of this Agreement.

     (d) Records.  Each Party shall calculate and maintain records of
         -------                                                     
Development Expenses incurred by it together with reconciling actual Development
Expenses versus Development Expenses advanced under Section 4.08(a).

     (e) Overruns. The Lead Development Party for a particular Collaboration
         --------                                                           
Compound and/or Collaboration Product shall be solely responsible for any
Development Expenses exceeding the most recently approved Development Budget for
that calendar year and such overage shall be charged to its account, unless the
overage is the result of actions of ORTHO (in which case ORTHO shall bear the
expense), or is the result of actions of ERGO (in which case ERGO shall bear the
expense), or is approved unanimously by the Steering Committee (in which cases
ORTHO shall be responsible for fifty percent (50%) of such Development Expenses
and ERGO shall be responsible for fifty percent (50%) of such Development
Expenses).

     4.09. Development Efforts: Royalty Bearing Territories.  In Developing
           ------------------------------------------------                
Royalty Bearing Products hereunder, ORTHO shall expend a commercially reasonable
level of effort that shall be commensurate with that expended on other ORTHO

<PAGE>
 
such an Initial Development Plan and Initial Development Budget within the sixty
(60) days, or a reasonable time thereafter as mutually agreed by the Parties,
joint Development shall not proceed and ORTHO's conditional acceptance shall be
deemed withdrawn. ERGO may or may not thereafter continue Pre-Selection
Activities as it in its sole discretion may determine. Upon final or
unconditional acceptance of a ERGO proposal, the Eligible Compound shall be
designated a Collaboration Compound for the accepted Metabolic Indication unless
and until discontinued or terminated as provided herein. Such Collaboration
Compound will be Developed jointly by the Parties through the JPT pursuant to
the provisions contained in Article IV and Commercialized pursuant to the
provisions contained in Article VII.

     (c) Development of an Eligible Compound for a Metabolic Indication by
         -----------------------------------------------------------------
ORTHO; Acceptance by ERGO: To the extent permitted under Section 5.01(a), ORTHO
- -------------------------                                                      
may commence Development of any Eligible Compound for a Metabolic Indication
without first offering such compound for joint Development pursuant to the
provisions contained in this Agreement, but such compound shall not be jointly
Developed and/or Commercialized as provided in, inter alia, Articles IV and VII
of this Agreement without first offering such compound  to ERGO for joint
Development as part of this collaboration and, subsequent to such offer, until
the Parties have agreed in writing to terms and conditions regarding the
Development and Commercialization of such Eligible Compound.  Such terms and
conditions for Development and/or Commercialization may differ from the terms
and conditions hereunder.  ORTHO has no obligation to offer any Eligible
Compound to the Collaboration for joint Development and/or Commercialization.

     (d) Election by a Party to Terminate Joint Development of a Collaboration
         ---------------------------------------------------------------------
Compound for a Metabolic Indication Accepted Under This Section 5.01.  For a
- --------------------------------------------------------------------        
Collaboration Compound being jointly Developed for a Metabolic Indication
pursuant to this Section 5.01 and Article IV, either Party may, subsequent to
its unconditional acceptance for Development and prior to its Commercialization,
by notice to the other party, terminate joint Development for such Metabolic
Indication. Termination shall be effective six (6) months after the date of
written notice; provided, however, that in the event that termination is the
result of a concern over Safety, termination shall be effective thirty (30) days
after written notice. In the event that ERGO so elects to terminate joint
Development for a Collaboration Compound for any Metabolic Indication, the joint
Development of such Collaboration Compound for all Indications and, if any,
Additional Indications, shall terminate.  Thereafter, ORTHO can convert the
Collaboration Product to an Independent Product for any Indications that,
immediately prior to such date of termination, were Development Indications or
Additional Indications or Indications contemplated in the Development Plan for
which Development had not yet begun (hereinafter the "Independent Indications"
with respect to the Independent Product defined in this subsection) and at its
option can:

          (i) pay ERGO a royalty on Royalty-Bearing Sales of such Independent
Product on a worldwide basis as follows: [*]

          (ii) account to ERGO for sales of the Independent Product for its
Independent Indications in the Profit/Loss Sharing Territory as though such
Independent Product had remained as a Collaboration Compound for such
Independent Indications; provided, however, should ORTHO so elect then (A) ERGO
shall not be obligated to make any Development Payments or Equalization Payments
when due in connection with such Independent Product, (B) ERGO may nonetheless
make all or part of such payments and such payments shall be credited to its
account, (C) if ERGO elects to defer all or part of such payments, any unpaid
balance will accrue interest at an annual interest rate equal to[*].
Notwithstanding any of the foregoing, the provisions of this subsection and
ORTHO's option as set forth in this subsection shall not apply wherever the
provision of Section 4.08(c) applies.  In such circumstances the provisions of
Section 4.08(c) shall apply and shall supersede the provisions of this
subsection.

          (iii) If ORTHO elects to terminate joint Development or
Commercialization of a Collaboration Compound being Developed or Commercialized
for a Metabolic Indication, the Collaboration Compound shall revert to an
Eligible Compound, unless, subsequent to the date of such termination, such
compound is continuing to be jointly Developed as a Collaboration Product for at
least one Development Indication; provided, however, that, in the event of
reversion to an Eligible Compound, such Eligible Compound may be Commercialized
by ERGO as an Independent Product for any Non-Metabolic Indication (the
Independent Indications for the Independent Product as described in this
subsection) that is an not an Indication that is being at such time and
thereafter continues to be Developed or Commercialized under this Agreement for
any then remaining Collaboration Compounds or ORTHO Independent Products.

         ---------------------------------------------------------------
Metabolic Indications:
- --------------------- 

          (i) Neither Party shall Develop or Commercialize any Eligible Compound
for a Non-Metabolic Indication except as provided in this Article V. Except for
the express provisions of this Agreement relating to the joint Development
and/or Commercialization of Collaboration Compounds and the express provisions
related to ORTHO's rights to Develop and/or Commercialize Independent Products,
ORTHO shall have the right to Develop and Commercialize Eligible Compounds for
Non-Metabolic Indications only to the extent that a Third Party, who has no
rights under ERGO Patents either express or implied, would be able to similarly
conduct such Development and/or Commercialization without infringing such
patents.

          (ii) Notwithstanding the provisions of paragraph (i) above, ERGO may,
however, in its sole discretion separately Develop or Commercialize, by itself
or with a Third Party, an Eligible Compound that is not a Collaboration Compound
or a product containing more than one active ingredient none of which is a
Collaboration Compound for any Non-Metabolic Indication. ERGO has no obligation
to offer any Eligible Compound that is not a Collaboration Compound to the
Collaboration for joint Development and/or Commercialization for a Non-Metabolic
Indication.

or more Non-Metabolic Indications during the term of this Agreement, provided,
however, such Collaboration Compound (other than Bromocriptine) is not
Commercialized as of the date on which ERGO begins Development for such
Collaboration Compound for such Non-Metabolic Indication(s).  If a Collaboration
Compound (other than Bromocriptine) is Commercialized before Development begins
for a Non-Metabolic Indication, ERGO may not Develop such Collaboration Compound
for a Non-Metabolic Indication.  The provisions of Section 5.01(b) relating to
the Development of Eligible Compounds for Metabolic Indications shall apply
mutatis mutandis, to the Development of Collaboration Compounds for such Non-
Metabolic Indications.

mutually agree on an Initial Development Plan and Initial Development Budget for
such Non-Metabolic Indication.

     (d) Election by a Party to Terminate Joint Development of a Collaboration
         ---------------------------------------------------------------------
Compound for a Non-Metabolic Indication Accepted Under This Section 5.02(b).
- --------------------------------------------------------------------------- 

          (i) For a Collaboration Compound being jointly Developed for a Non-
Metabolic Indication pursuant to this Section 5.02 and Article IV, either Party
may, subsequent to its acceptance for Development, by notice to the other party
terminate joint Development for such Non-Metabolic Indication.  Termination
shall be effective [*] after the date of notice; provided, however, that in the
event that termination is a result of a concern over Safety or Tolerability,
termination shall be effective [*] after such notice.  In the event that ERGO so
elects to terminate joint Development for a Collaboration Compound for a Non-
Metabolic Indication, the joint Development of such Collaboration Compound for
such Indication shall terminate.  Thereafter ORTHO shall have the option set
forth in Section 5.01(d), applied mutatis mutandis.

          (ii) Notwithstanding the foregoing, if at the time of termination by
ERGO of a Non-Metabolic Indication, the Collaboration Compound is being jointly
Developed and/or Commercialized for another Indication, ORTHO shall only have
the option to either discontinue Development of the Collaboration Compound for
the Non-Metabolic Indication being terminated by ERGO or Develop it as an
Independent Product for the terminated Non-Metabolic Indications (the
"Independent Indications" for the Independent Product defined in this
subsection), but only Commercialize it under a trademark which is different from
the one being used with the jointly Developed Collaboration Product for the
Metabolic Indication(s).  In such case, the option set forth in Section 5.01(d)
shall not apply; provided, however, that the royalty rates for such Independent
Product shall be as recited in Section 5.01(d) above.

          (iii) If ORTHO elects to terminate joint Development or
Commercialization for a Collaboration Compound for all extant Development
Indications and/or Additional Indications, such compound thereby becomes an
Eligible Compound; provided, however, that, in the event of reversion to an
Eligible Compound, such Eligible Compound may be Commercialized by ERGO as an
Independent Product for any Non-Metabolic Indication (the Independent
Indications for the Independent Product as described in this subsection) that is
an not an Indication that is being at such time and thereafter continues to be
Developed or Commercialized under this Agreement for any then remaining
Collaboration Compounds or ORTHO Independent Products.

          (iv) If ERGO is the non-terminating party and commercializes the
Independent Product for the Independent Indication by itself or with a Third
Party, then ERGO shall pay to ORTHO a royalty on Net Trade Sales of such
Independent Product for the Independent Indication in the Profit-Loss Sharing
Territory.  The royalty shall be as follows: [*]

and Commercialized pursuant to this Agreement, Bromocriptine for the Diabetes
Indication and/or Obesity Indication shall have the status of a Collaboration
Compound for Metabolic Indications and the provisions of Section 5.01 relating
to the Development and/or Commercialization of an Eligible Compound for a
Metabolic Indication shall apply mutatis mutandis to the Development and
Commercialization of Bromocriptine for a Metabolic Indication, except as
otherwise provided in this Section 5.03.

     (b) Election by a Party to Terminate Joint Development or Commercialization
         -----------------------------------------------------------------------
of Bromocriptine for a Metabolic Indication.
- ------------------------------------------- 
 
          (i) If ORTHO terminates joint Development Activities or
Commercialization of Bromocriptine for one or more Metabolic Indications, then
all rights to further Develop and/or Commercialize Bromocriptine for each such
Metabolic Indication shall revert to ERGO and shall not be further subject to
limitation or other provision of this Agreement, unless Bromocriptine or another
Collaboration Compound has been and is continuing to be Developed and/or
Commercialized pursuant to this Agreement for one or more Metabolic Indications.
In such event, no rights with respect to Bromocriptine as set forth in this
subsection shall revert to ERGO.
 
          (ii) If ERGO terminates joint Development Activities or
Commercialization (other than pursuant to Section 4.08(c) or Section 8.02) with
respect to Bromocriptine for a Metabolic Indication, then joint Development
and/or Commercialization of Bromocriptine for all Indications shall terminate.
Thereafter, ORTHO, at its option can:

               (A) convert the Profit/Loss Sharing Territory to a Royalty
Bearing Territory for such Collaboration Product and convert such Collaboration
Product to an Independent Product and pay ERGO a royalty of [*] or

               (B) account to ERGO for sales of the Independent Product for its
Independent Indications in the Profit/Loss Sharing Territory as though such
Independent Product had remained as a Collaboration Product for such Independent
Indications; provided, however, should ORTHO so elect then (1) ERGO shall not be
obligated to make any Development Payments or Equalization Payments when due in
connection with such Independent Product, (2) ERGO may nonetheless make all or
part of such payments and such payments shall be credited to its account, (3) if
ERGO elects to defer all or part of such payments, any unpaid balance will
accrue interest at[*].

     Notwithstanding any of the foregoing, the provisions of this subsection and
ORTHO's option as set forth in this subsection shall not apply whenever the
provisions of Section 4.08(c) or Section 8.02 are applicable.  In such
circumstances the provisions of Section 4.08(c) or Section 8.02 shall apply and
shall supersede the provisions of this subsection.

     SECTION 5.04. Development and Commercialization of Bromocriptine for a Non-
                   ------------------------------------------------------------
Metabolic Indication.
- ---------------------

     (a) The provisions of Section 5.02 relating to the Development and/or
Commercialization of an Eligible Compound for a Non-Metabolic Indication shall
apply mutatis mutandis to the Development and Commercialization of Bromocriptine
for a Non-Metabolic Indication, except as otherwise provided in this Section
5.04.  Regardless of whether Bromocriptine has been or is being or has yet to be
Commercialized, ERGO shall have the right to initiate Development of
Bromocriptine for any Indication(s) not then extant Development Indications or
extant Additional Indications of Bromocriptine.

     (b) Notwithstanding paragraph (a) above, if ORTHO terminates joint
Development of Bromocriptine for a Non-Metabolic Indication or ORTHO never
elects to participate jointly in such Development as provided in this Agreement,
then ERGO may  (subject to Section 8.12) Develop and/or Commercialize
Bromocriptine for the Non-Metabolic Indication as an Independent Product (with
such Non-Metabolic Indication being the "Independent Indication" for the
Independent Product defined under 


                                      29

this subsection) by itself or with a contract sales force (but by no other
means). For such Independent Product, in the Profit/Loss Sharing Territory, ERGO
must adopt its own mark and, [*]. In any country outside of the Profit/Loss
Sharing Territory, ERGO must adopt its own mark which is different from that
being currently used in such country by ORTHO for Bromocriptine and may only
Commercialize in such country an Independent Product that is administered
through a different route of administration from any Bromocriptine Product then
currently being jointly Developed and/or Commercialized for sale in such
country, subject to the following:

          (i) if, following such termination or failure to participate by ORTHO,
Bromocriptine is not then a Collaboration Compound, ERGO may further Develop
and/or Commercialize Bromocriptine as an Independent Product with a Third Party
without further restriction or obligation to ORTHO, provided, however, ERGO may
not Develop and/or Commercialize Bromocriptine for any Indication for which a
Collaboration Compound is currently being Developed or Commercialized.

     (c) If ERGO terminates joint Development or Commercialization of
Bromocriptine for a Non-Metabolic Indication, ORTHO shall only have the option
to either discontinue Development of Bromocriptine for the Non-Metabolic
Indication being terminated by ERGO or Develop it as an Independent Product for
such Non-Metabolic Indication (the "Independent Indication" for the Independent
Product as defined in this subsection), but only Commercialize it under a
trademark which is distinctively different from any mark being used with the
jointly Developed and/or Commercialized Bromocriptine for the Metabolic
Indication(s).  The royalty rates for the Independent Product shall be the rates
as recited in 5.01(d).

     SECTION 5.05. Milestone Payments for Non-Metabolic Indications.
                   ------------------------------------------------ 

     (a) If ORTHO shall have exercised an option pursuant to Sections 5.02 or
5.04, then ORTHO shall pay to ERGO a one-time payment of [*]("Non-Metabolic
Indication Milestone Payment") within fifteen (15) business days after the first
exercise of ORTHO's option pursuant to Section 5.02 or 5.04 to commence
participation in Development and/or Commercialization of the first Collaboration
Compound for a Non-Metabolic Indication.  The [*] Non-Metabolic Indication
Milestone payment set forth in this paragraph shall be payable only once for the

otherwise has the right to so sell and/or distribute such products in such
countries.

     SECTION 6.08. Sublicensing.  ORTHO may grant sublicenses under Sections
                   ------------                                             
6.01, Section 6.03 and Section 6.04 only with the express prior written approval
of ERGO (which approval will not be unreasonably withheld or delayed); provided,
                                                                       -------- 
however, that (i) ORTHO may only sublicense a Third Party to sell or have sold
Collaboration Product only in the Royalty Bearing Territory, and (ii) ORTHO may
proceed with distribution and sale of a Collaboration Product in the Profit/Loss
Sharing Territory and in the Royalty Bearing Territory through its usual and
customary distributors performing their usual and customary distribution
activities for ORTHO without ERGO's prior written approval of any necessary
sublicenses in connection therewith.  With respect to Independent Products, the
Party having a license with respect to such Independent Products shall have a
right to sublicense under such license with respect to such Independent Products
without approval of the other Party.

     SECTION 6.09. Third Party Technology.
                   ---------------------- 

     (a) The licenses granted under Sections 6.01, 6.02, and 6.03 include
sublicenses of Third Party technology to the extent that such sublicenses can be
so granted

     (b) The licenses granted under Section 6.01, Section 6.02, and Section 6.03
to the extent they include sublicenses of Third Party technology, in any event,
shall be subject to the terms and conditions of the license agreement pursuant
to which the underlying license, and the sublicensing rights thereunder were
granted.

     SECTION 7.01. ORTHO as Marketing Party.
                   ------------------------ 

     (a) ORTHO will be the marketing Party with respect to all Collaboration
Products in the Profit/Loss Sharing Territory and the Royalty Bearing Territory.
As marketing party ORTHO shall have full and exclusive decision making authority
with respect to all Commercialization Activities for all Collaboration Products
in the Profit/Loss Sharing Territory and the Royalty Bearing Territory, except
as otherwise set forth in this Agreement.

     SECTION 7.02. Commercialization Efforts.
                   ------------------------- 

     (a) ORTHO agrees to use commercially reasonable efforts to Commercialize
Collaboration Products.  Such commercially reasonable efforts shall be
consistent with the efforts used by ORTHO (in each case comparable efforts will
be measured against the efforts used by ORTHO's principal pharmaceutical
marketing Affiliateresponsible for marketing in the country where
Commercialization Activities take place for that Collaboration Product) in
preparing commercialized plans and budgets and 

                                       32
<PAGE>
 
commercializing its own pharmaceutical products (that are similar with regard
to, for example, market potential, price per treatment, patient population and
competitive position). For example, with regard to the determination of all
pricing, cost of goods, sampling, and discounting strategies for Collaboration
Products, ORTHO shall use a substantially similar approach than that employed by
ORTHO in determining such strategies for their pharmaceutical products.

     (b) ERGO shall designate a Commercialization liaison who will function as
the contact person at ERGO to receive information from ORTHO relating to
Commercialization of Collaboration Products.  ORTHO shall provide to such
liaison, on a timely basis, general management reports that are available to the
management board of ORTHO directed to the Commercialization Activities of each
Collaboration Product in the Profit/Loss Sharing Territory and other Information
regarding such Commercialization Activities that ORTHO considers necessary and
appropriate to keep ERGO appraised of such Commercialization Activities. ERGO
shall have the right to change the liaison at ERGO's discretion and shall
promptly inform ORTHO of such change.

     (c) Commercialization Plan and Budget.  ORTHO shall submit to ERGO a
         ---------------------------------                               
commercialization plan ("Commercialization Plan") for each Collaboration Product
for the Profit/Loss Sharing Territory, which shall be comparable to existing
marketing and or business plans for similar products developed at such time by
ORTHO within the Profit/Loss Sharing Territory, and a commercialization budget
("Commercialization Budget") for each Collaboration Product, initially for each
extant Development Indication and each extant Additional Indication for the
Profit/Loss Sharing Territory.  Such Commercialization Plan shall include
estimated sales for the upcoming year and a rough estimate of sales for the year
following the date of such plan.  In addition, the Commercialization Plan shall
identify co-promotion arrangements, if any, and contract sales force
arrangements, if any.  Each Commercialization Budget shall include a budget of
the expenses expected to be incurred in connection with performing the
Commercialization Plan, including Pre-Marketing Expenses and Allowable Operating
Expenses in the Profit/Loss Sharing Territory.  On or about December 1 of each
year, or earlier if available, ORTHO will provide the Commercialization Plan and
Commercialization Budget to ERGO for at least the subsequent calendar year and,
so long as ORTHO maintains its current two-year forecasting cycle on which to
base such estimates, at least the subsequent two calendar years.  ORTHO shall
make all final decisions with respect to Commercialization Plans and
Commercialization Budgets (except for the costs of the Phase IIIB Clinical
Trials described in Exhibit E).  Any significant change in a Commercialization
Plan or Commercialization Budget made by ORTHO during the course of the year
will be communicated promptly to ERGO.

     (d) Launch Plan.  Each Commercialization Plan shall be updated, in advance
         -----------                                                           
of the launch of the applicable Collaboration Product in the Profit/Loss Sharing
Territory, to include a launch plan ("Launch Plan") and launch budget ("Launch
Budget") for such launch, covering the period twelve (12) months, if
practicable, before said launch, and the twelve (12) month period, if practical,
following the launch date.  Each such Launch Plan and Launch Budget shall be
developed by ORTHO at a point in time prior to launch which is reasonable with
respect to the proposed launch of the particular Collaboration Product and
provided to ERGO promptly thereafter.  It is understood that, for Bromocriptine
for the Type II Diabetes Indication, because of the shortness of time between
NDA filing and the presently anticipated launch date, the Launch Plan & Budget
may be in an abbreviated form and submitted to ERGO prior to launch and as soon
as it is prepared by ORTHO.  Each Launch Plan shall include (i) updated market
and sales forecasts in units and estimated revenues of Collaboration Product,
(ii) estimated resource requirements and (iii) such other matters deemed
appropriate by ORTHO.  With respect to Bromocriptine for the Type II Diabetes
Indication, ORTHO shall prepare and provide to ERGO within sixty (60) days from
the Effective Date, a Commercialization Budget for the six (6) month period
following the Effective Date.

     SECTION 7.03. Commercialization in Royalty Bearing Territory.
                   ---------------------------------------------- 

     (a) Commercialization of Royalty Bearing Products and Independent Products
in the Royalty Bearing Territory shall be conducted independently by Affiliates
of ORTHO and decisions regarding, for example, pricing, advertising, and product
recalls shall be the sole responsibility of ORTHO's Affiliate, provided,
however, that such Affiliate's Commercialization Activities with respect to
Royalty Bearing Products shall be consistent with the activities of such
Affiliate in commercializing its own pharmaceutical products that are similar
with regard, for example, to market potential, price per treatment, patient
population, and competitive position. ORTHO shall be responsible for all
Commercialization costs and expenses in the Royalty Bearing Territory.   With
respect to Independent Products, neither Party shall have any obligations to
undertake Commercialization Activities.  ERGO shall not be responsible for any
costs or expenses of Commercialization in any country in the Royalty Bearing
Territory.

     (b) In the event that ORTHO decides not to commence Commercialization in
any country in the Royalty Bearing Territory, ORTHO shall have the right, but
not the obligation, subject to the terms of Section 6.08 of this Agreement to
license such rights to a Third Party.  ORTHO shall report all sales made by a
sublicensee as if such sublicensee's sales were ORTHO sales in the Royalty
Bearing Territory and ORTHO shall pay to ERGO royalties on such sales in
accordance with the provisions of Article VIII of this Agreement.

     SECTION 7.04. Pricing, Pricing Approvals and Product Distribution.  ORTHO
                   ----------------------------------------------------       
shall set all prices for all Collaboration Products, shall obtain for
Collaboration Products pricing approvals as may be required, shall be
responsible for distribution of each Collaboration Product in the Profit/Loss
Sharing Territory and in the Royalty Bearing Territory and shall book all sales
for Collaboration Products.

     SECTION 7.05. Product Recalls.  If ORTHO believes that a recall of a
                   ---------------                                       
Collaboration Product is necessary, ORTHO shall promptly undertake such recall
following notification to ERGO. The decision of ORTHO concerning such recall
shall be final.

     SECTION 7.06. Tax Considerations.  Either Party may take advantage of
                   ------------------                                     
provisions of law and/or administrative regulation or practice that favorably
affect its tax obligations, but not those of the other Party.  In the event that
a Party takes advantage of such a tax consideration in connection with a
Collaboration Product in the Profit/Loss Sharing Territory which benefits it,
but not the other Party, no compensation to the other Party shall be required
except to the extent such tax consideration negatively affects the other Party's
share of Operating Profits or Losses.  In such event, sufficient compensation
shall be provided to the other Party to place such other Party in the position
that it would have been in had the advantage for such tax consideration not been
realized.

     SECTION 7.07. Advertising and Promotion.  With respect to printed
                   -------------------------                          
promotional (including advertisements appearing in journals) materials or
printed educational materials for Collaboration Products in the Profit/Loss
Sharing Territory, ERGO's name will appear on such materials and that reference
to ERGO shall be in the form that references ERGO as the licensing party,
provided such is permitted by the applicable laws and regulations.  On all other
materials in the Profit/Loss Sharing Territory, including but not limited to
product labeling, the product label, and documentary information, and on all
materials in the Royalty Bearing Territory, including but not limited to
promotional and advertising materials, reference to ERGO shall not appear unless
mutually agreed to by the Parties.

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

     SECTION 8.01. Share of Operating Profits or Losses.
                   ------------------------------------ 

     (a) Equal Share of Operating Profits and Losses. ERGO and ORTHO shall share
         -------------------------------------------                            
equally (50% to ORTHO and 50% to ERGO) in Operating Profits and Losses from the
Development and Commercialization of Collaboration Compounds and Collaboration
Products in the Profit/Loss Sharing Territory, except to the extent the
provisions of Section 8.01(d) apply.

     (b) Profit and Loss Sharing Mechanism.  All sales of Collaboration Products
         ---------------------------------                                      
in the Profit/Loss Sharing Territory shall be booked by ORTHO.  ORTHO shall have
the right to reject any order received by it for a Collaboration Product;
provided, however, that ORTHO shall not reject orders on an arbitrary basis, but
only with reasonable justification and consistent with the general policies
applied by it with respect to orders for other pharmaceutical products sold by
it.

     (c) LSU Royalty and Other Pre-Existing Third Party Royalties.  The royalty
         --------------------------------------------------------              
payable to Louisiana State University under LSU Patents for sales of
Collaboration Products in the Profit/Loss Sharing Territory shall be an
Allowable Expense, and ERGO and ORTHO shall each be responsible for 50% of such
royalty. The royalty payable to Louisiana State University under LSU Patents for
sales of Collaboration Products in any former Profit/Loss Sharing Territory
shall be borne equally by the parties, and ORTHO, in addition to any other
royalties payable to ERGO pursuant to the terms of this Agreement in a former
Profit/Loss Sharing Territory ORTHO shall pay to ERGO [*] of the royalty amount
due LSU under the LSU Agreement.  ERGO shall be responsible for payment of
royalties to LSU and shall provide written documentation to ORTHO of such
payment of royalties for purposes of calculating Operating Profits and Losses by
ORTHO and for the purposes of verifying the correctness of ORTHO's payments with
respect to the former Profit/Loss Sharing Territory.  ORTHO shall not be
responsible in the Profit/Loss Sharing Territory or the Royalty Bearing
Territory for any portion of any royalty owed to any Third Party pursuant to an
agreement between ERGO and such Third Party that existed prior to the Effective
Date, other than as set forth above with respect to royalties in the Profit/Loss
Sharing Territory due to LSU.

     (d) Change in Profit and Loss Sharing Percentages. [*].
               ---------------------------------------      

     SECTION 8.02. Profit/Loss Sharing Reports and Payments.
                   ---------------------------------------- 

     (a) Reports. The parties shall make Commercial Equalization Payments to one
         -------                                                                
another as required to effect the sharing of profits and losses as provided in
this Article VIII.  Within thirty (30) days after the end of each calendar
quarter and fifty (50) days after the end of the fourth quarter of each full
calendar year, ORTHO shall report to ERGO (as outlined in Exhibit B) its
revenues and individual Allowable Expense items (with appropriate supporting
information) involved in the computation of Operating Profits or Losses
attributable to such quarter with respect to such Collaboration Product. ERGO
shall similarly report in writing to ORTHO within the same thirty (30) day
period, any Allowable Expense (with appropriate supporting information) items
that it has incurred, including but not limited to the LSU Royalty.  Within
thirty (30) days after receipt of the last of such reports, ORTHO shall provide
to ERGO a written Product Financial Statement with respect to each Collaboration
Product, and a Consolidated Financial Statement with respect to all
Collaboration Products for the Profit/Loss Sharing Territory. The reports and
Equalization Payments for each of the first three quarters of each fiscal year
may be based on estimated operating profits and losses for such quarters to the
extent such estimates are included in such Party's books and records.  The
reports and Equalization Payments for the fourth quarter 

                                       35
<PAGE>
 
of each fiscal year shall include reconciliation and year-end adjustments, if
necessary and to the extent available, with respect to previous quarters. A
Commercial Equalization Payment by ORTHO to ERGO for a particular quarter
required by this Section 8.02 shall be made in any event within forty-five (45)
days of the due date of the Product Financial Statement. The Product Financial
Statements and the Consolidated Financial Statement required hereunder shall be
in the format shown on Exhibit B attached hereto.

     (b) Time Periods and Payments by ERGO.
         --------------------------------- 

          (i)   Except during the Launch Payment Period (as hereinafter
defined), within forty-five (45) days after the due date or receipt by ERGO of a
written Product Financial Statement from ORTHO, whichever is later, indicating
that a Commercial Equalization Payment for a particular quarter is to be made by
ERGO to ORTHO, ERGO shall make such Commercial Equalization Payment to ORTHO;
provided, however, the forty-five (45) day period shall be instead a sixty (60)
day period for the first three calendar quarters of 1998 and any and all
references in this Article VIII to such forty-five (45) day period shall instead
be deemed references to a sixty (60) day period.

          (ii)  During the Launch Payment Period, within forty-five (45) days
after the due date or receipt by ERGO of a written Product Financial Statement,
whichever is later, indicating that a Commercial Equalization Payment for a
particular quarter is to be made by ERGO to ORTHO pursuant to Section 8.02(a),
ERGO shall make such Commercial Equalization Payment to ORTHO within such forty-
five (45) day period at least to the extent that the Commercial Equalization
Payment is not more than the Capped Equalization Amount for that quarter. As
used herein, "Capped Equalization Amount" means [*] of the Forecasted
Equalization Payment for such particular quarter. For this purpose, the
Forecasted Equalization Payment is the Commercial Equalization Payment
forecasted by ORTHO and provided to ERGO at least [*]months prior to such
quarter, except that, during the [*]months following the Effective Date, the
forecast provided at the Effective Date shall represent the forecast used for
such quarters during such [*]month period.  ORTHO shall send to ERGO a forecast
of Net Trade Sales and Allowable Expenses, excluding Development Expenses, that
is materially the same as the forecast that it uses for internal financial
planning purposes.

     In the event that during the Launch Payment Period, the full amount of the
  Commercial Equalization Payment to be made by ERGO to ORTHO for a particular
  quarter is greater than the Capped Equalization Amount for such quarter ERGO
  may elect to pay ORTHO within such forty-five (45) day period only an amount
  that is less than the full amount of the Commercial Equalization Payment,
  provided that such lesser amount is at least equal to the Capped Equalization
  Amount. If ERGO so elects to pay such lesser amount, then ERGO shall have a
  period of [*]months from the due date or actual date of receipt of the
  relevant Product Financial Statement, whichever is later, to pay ORTHO an
  Excess Equalization Payment, together with interest on the Excess Equalization
  Payment, such interest to be payable at an annual rate of[*], beginning on the
  day following the end of said forty-five (45) day period (such Excess
  Equalization Payment and interest together being the "Compounded Excess
  Equalization Payment"). Where ERGO pays an amount that is less than the full
  amount of the Commercial Equalization Payment, but at least the Capped
  Equalization Amount specified in this subsection, "Excess Equalization
  Payment" shall mean the amount of the excess, if any, by which the Commercial
  Equalization Payment owed by ERGO to ORTHO for a particular quarter exceeds
  the amount actual paid by ERGO. "Launch Payment Period" shall mean the period
  beginning on the later of: (i)[*], or (ii)[*]; and ending on[*].

          (iii) In the event that ERGO fails to make a payment that is at least
the lesser of  the full amount of the Commercial Equalization Payment or the
Capped Equalization Amount within the forty-

                                       36
<PAGE>
 
five (45) day period as set forth herein or ERGO fails to make a payment that is
the full amount of the Compounded Excess Equalization Payment within the
[*]month period as set forth herein, ORTHO shall send a past-due notice to ERGO
stating that ERGO has failed to make a payment within the required time period
set forth in subsection 8.02(b). If, pursuant to such notice, ERGO does not pay
any such amount, plus a penalty of [*] of the overdue amount thereon, to ORTHO
within thirty (30) days after receipt of such late notice from ORTHO, ERGO shall
be deemed to have defaulted in its payment obligation to ORTHO pursuant to this
subsection 8.02(b).

     (c) In the event that ERGO has defaulted in making a payment that is
either the full amount of the Commercial Equalization Payment Amount (where such
Capped Equalization Amount is greater than or the same as the amount of the
corresponding Commercial Equalization Payment) or at least the Capped
Equalization Amount (where such Capped Equalization Amount is less than the
amount of the corresponding Commercial Equalization Payment) as provided in
subsection 8.02(b)(iii) above, ORTHO at its option, may:

          (i) convert the Profit/Loss Sharing Territory to a Royalty Bearing
Territory for the Collaboration Product with respect to which the payment was
not made and pay ERGO a royalty percentage of[*]; or

          (ii) maintain the Profit/Loss Sharing Territory as a Profit/Loss
Sharing Territory for the Collaboration Product with respect to which the
payment was not made.  The unpaid balance as of the date of default, including
the [*] charge pursuant to Section 8.02(b)(iii), will accrue interest at an
annual interest rate equal to the[*].  Such interest will be added to the past
due balance.  The parties shall thereafter continue to share equally in the
Operating Profits and Operating Losses for such Product; provided, however, that
no payments attributable to such Collaboration Product, including royalties,
milestones or Equalization Payments, shall be made to ERGO until the past due
balance plus interest and fees as defined above are fully recovered.

     (d) Notwithstanding Section 8.02(c), in the event that ERGO has made a
payment at least in the amount of the Capped Equalization Amount (where such
Capped Equalization Amount is less than the amount of the corresponding
Commercial Equalization Payment) for a particular period, but defaults in making
a Compounded Excess Equalization Payment pursuant to subsection 8.02(b)(iii),
ORTHO at its option, may:

          (i) convert the Profit/Loss Sharing Territory to a Royalty Bearing
Territory for the Collaboration Product with respect to which payment was not
made and pay ERGO a royalty percentage of [*] or

          (ii) maintain the Profit/Loss Sharing Territory as a Profit/Loss
Sharing Territory for the Collaboration Product with respect to which the
payment was not made. The unpaid balance as of the date of default, which
includes the [*] pursuant Section 8.02(b)(ii) and the [*]charge pursuant to
Section 8.02(b)(iii), will accrue interest at an annual rate equal to the[*].
Such interest will be added to the past due balance.  The parties shall
thereafter continue to share equally in the Operating Profits and Operating
Losses for such Product; provided, however, that no payments attributable to
such Collaboration Product, including royalties, milestones or Equalization
Payments, shall be made to ERGO until the past due balance plus interest and
fees as defined above are fully recovered.

     (e) In the event that ERGO defaults as described in Section 8.02(b)(iii)
above with respect to a particular Collaboration Product, ORTHO shall make an
election to convert the Profit/Loss Sharing Territory to a Royalty Bearing
Territory with respect to the Collaboration Product for which payment 

                                       37
<PAGE>
 
was not made in Section 8.02(c) or 8.02(d) above (whichever is applicable), if
at all, within the sixty (60) day period following the date on which ERGO is
deemed to have defaulted in making such payment; provided, however, that in the
event ORTHO once elects not to make such a conversion with respect to a
particular Collaboration Product, such election shall not thereafter be
available again to ORTHO with respect to such Collaboration Product based on a
default under Section 8.02(b)(iii).

     (f) In the event that ERGO defaults pursuant to Section 8.02(b)(iii), such
default shall not be a material breach of this Agreement pursuant to Section
14.02 and the remedies for such default shall be limited to the remedies
provided in this Section 8.02.

     SECTION 8.03. Term. The Parties shall share Operating Profits or Losses
                   ----                                                     
hereunder with respect to each Collaboration Product in the Profit/Loss Sharing
Territory until such Collaboration Product is permanently withdrawn from and is
no longer being sold in the Profit/Loss Sharing Territory.

     SECTION 8.04. Royalty Bearing Products.
                   ------------------------ 

     (a) ORTHO shall pay to ERGO a royalty equal to the applicable Royalty
Percentage set forth below on Royalty Bearing Sales of Bromocriptine in the
Royalty Bearing Territory as follows:


              ---------------------------------------------------
                          [*]                        [*]
              ---------------------------------------------------
               [*]                      [*]
              ---------------------------------------------------
                [*]                      [*]   
              ---------------------------------------------------

     [*]

     (b) ORTHO shall pay to ERGO a royalty equal to: [*] for each Collaboration
Product other than Bromocriptine, in the Royalty Bearing Territory[*] for each
Collaboration Product other than Bromocriptine in the Royalty Bearing Territory.
For example,[*].

     (c) Except where expressly provided otherwise in this Agreement, all
royalties to a Party shall be paid, on a country-by-country basis, from the date
of the first commercial sale of each Royalty Bearing Product in a particular
country until the later of (i) [*] from the first commercial sale in such
country and (ii) the last to expire of any valid and enforceable ERGO Patents or
Joint Patents, as applicable, which would have been infringed by the use or sale
of the Royalty Bearing Product in such country, absent rights thereunder:

          (i) If a Royalty Bearing Product is sold in any country for an
Indication for which ERGO does not have valid patent coverage (whether through
invalidation or abandonment or by virtue of the fact that a patent application
has never been filed which contains a claim providing such coverage) that would
prevent the use or sale of a generic form of such Royalty Bearing Product for
such Indication and, further, a generic equivalent of such Royalty Bearing
Product, labeled for such Indication, is being sold, the royalty obligation set
forth in Section 8.04 (a) or Section 8.04(b) above with respect to such
Indication for such Royalty Bearing Product in such country shall be reduced
by[*], until ERGO is granted such valid and enforceable patent coverage of such
Indication for such Royalty Bearing Product in such country;

          (ii) If a Royalty Bearing Product is being sold in any country with
respect to which a Third Party (other than LSU under LSU Patents) has a patent,
from which ERGO has not obtained a 

                                       38
<PAGE>
 
license, and is entitled to receive royalties pursuant to a patent license
required in order to make or sell the Royalty Bearing Product, then the royalty
obligation set forth in Section 8.04(a), or Section 8.04(b) above with respect
to Royalty Bearing Sales attributable to the sale of such Royalty Bearing
Products in such country shall be reduced by one-half of the royalty payable to
such Third Party, but not below [*]of the amount of the royalty that would,
absent such payment, be otherwise payable under Section 8.04(e);
 
          (iii) If a Royalty Bearing Product is being sold in a country for an
Indication where the only ERGO Patent that exists that covers the Royalty
Bearing Product is a pending patent application which has been pending for[*],
whichever is later, and a generic equivalent of such Royalty Bearing Product,
labeled for such Indication, has been approved for commercial sale, then ORTHO
shall be entitled thereafter to a [*]reduction in the royalty payable to ERGO in
such country with respect to such indication of such product as set forth in

          (iv) Royalty Reduction for Off-Label Sales.  In the event that the
               -------------------------------------                        
Royalty Bearing Sales of any Royalty Bearing Product in a country outside the
United States are determined to have been reduced as a result of Off-Label Sales
of a product containing the same active ingredient as a particular Collaboration
Product by an amount in excess of [*] of the Royalty Bearing Sales that would
have been realized but for the Off-Label Sales, then ORTHO shall be entitled to
take a reduction in the royalties payable with respect to such Royalty Bearing
Product in such country for any calendar quarter in which such Royalty Bearing
Sales are so reduced by at least[*].  The reduction in royalties shall equal [*]
of such reduction in such Royalty Bearing Sales in excess of such[*], but in no
event greater than [*] of the Royalty Bearing Sales in such country for such
quarter (i.e., the Royalty Percentage for any such country shall not be so
reduced by more than[*].[*].

          (v) Notwithstanding the provisions of Section 8.04(c), subsections
(i), (ii), (iii) and (iv) above, the royalties to be paid by ORTHO to ERGO on
Royalty Bearing Sales pursuant to Section 8.04(a) and Section 8.04(b) shall
never be reduced in the aggregate by more than [*] from the royalties applicable
in the absence of such reductions.
 
     (f) Upon expiration of the royalty term for a Royalty Bearing Product in a
country as described above, ORTHO shall thereafter have a paid-up, non-exclusive
license to make, have made, use, sell, offer for sale, have sold and import that
Royalty Bearing Product in that country.

     (h) ORTHO shall not be responsible for payment of any portion of any
royalty owed to any Third Party based on Royalty Bearing Sales in the Royalty
Bearing Territory, including LSU under the LSU Patents, pursuant to any
agreement between such Third Party and ERGO that existed prior to the Effective
Date.

     SECTION 8.05. Sales by Sublicensees.  In the event either Party, subject to

the provisions of this Agreement, grants licenses or sublicenses to others to
make or sell Royalty Bearing Products or Independent Products, such licenses or
sublicenses shall include an obligation for the licensee or the sublicensee to
account for and report its Royalty Bearing Sales of such Royalty Bearing
Products or Independent Products on the same basis as if such sales were Royalty
Bearing Sales by the Party, and such Party shall pay royalties to the other
Party as if the Royalty Bearing Sales of the sublicensee were Royalty Bearing
Sales of the Party granting the license or sublicense.

     SECTION 8.06. Royalty Reports and Payments.  A report, summarizing the
                   ----------------------------                            
Royalty Bearing Sales of any Royalty Bearing Products and/or Independent
Products during the relevant quarter on a

country-by-country basis, together with payment of the royalties payable in
accordance the report shall be delivered to the receiving Party within sixty
(60) days following the end of each calendar quarter and sixty (60) days
following the end of each calendar year for which royalties are due from the
selling Party.

     SECTION 8.07. Payments.  Any payments due under this Agreement shall be
                   --------                                                 
made by wire transfer to a designated bank account of the receiving Party, as
such may be directed in writing by the recipient.

     SECTION 8.08. Taxes.  The Party receiving royalties shall pay any and all
                   -----                                                      
taxes levied on account of royalties it receives under this Agreement.  If laws
or regulations require that taxes be withheld, the selling Party will (i) deduct
those taxes from the otherwise remittable royalty, (ii) timely pay the taxes to
the proper taxing authority, and (iii) send proof of payment to the other Party
within thirty (30) days of receipt of confirmation of payment from the relevant
taxing authority.  The selling Party agrees to take all lawful and reasonable
efforts to minimize such taxes to the other Party.

such currency shall be converted into United States Dollars in accordance with
the Party's customary and usual translation procedures consistently applied and
in accordance with generally accepted accounting principles.

     SECTION 8.10. Payments to or Reports by Affiliates.  Any payment required
                   ------------------------------------

required to be made by any Party shall be made to or by an Affiliate of that
Party if designated by that Party as the appropriate recipient or reporting
entity.

     SECTION 8.11. No Overlapping Royalties.  Notwithstanding any other
                   ------------------------                            
provision of this Agreement, in no event shall any royalty provided for under
any Section of this Agreement be paid with respect to any sale of a
Collaboration Product, Independent Product or Royalty-Bearing Product to the
extent a royalty has been paid pursuant to any other Section of this Agreement
with respect to such sale provided that the higher royalty is paid.

     SECTION 8.12. Spillover Sales and Equalization Payment Based on Spillover
                   -----------------------------------------------------------
Sales.
- ----- 

     (a) During the term of this Agreement, either ORTHO or ERGO may decide to
terminate Development of Bromocriptine for an Indication pursuant to Section
5.04, such that, in the Profit/Loss Sharing Territory, a Bromocriptine-
containing product ("Product" as used in this subsection) might be marketed,
promoted and sold separately by one Party (the "Approved Indication Selling
Party") for an Indication which is different from any Indication for which the
Product is approved for use and Commercialized by the other Party, including a
sublicensee of such Party (the "Spillover Selling Party").  Each Indication for
use for which the Approved Indication Selling Party has regulatory approval to
market, but the Spillover Selling Party does not, shall be referred to as a
"Spillover Indication" and any sales of a Product made by the Spillover Selling
Party where the Product is thereafter used for such a Spillover Indication shall
represent "Spillover Sales" with respect to such Party's Product.

     (b) Based on the determination of the Spillover Sales of the Product, the
Spillover Selling Party shall make an annual payment (the "Spillover
Equalization Payment") to the Approved Indication Selling Party, such payment to
be made within three (3) months from the end of each calendar year.  The
Spillover Equalization Payment shall be in an amount such that the Approved
Indication Selling Party shall realize the profits it would have made had the
Approved Indication Selling Party itself made such Spillover Sales.   In the
event that the Spillover Selling Party is only Commercializing the Product by

                                       40
<PAGE>
 
route of administration different from each of the forms of the Product sold by
the Approved Indication Selling Party, no Spillover Equalization Payment shall
be made.

     (c) The parties will establish a mechanism to determine Spillover Sales of
Products based on each Spillover Indication at such time, if ever, that ORTHO
fails to accept the ERGO proposal for joint Development made following [*](e.g.,
ERGO may, therefore, become the Spillover Selling Party for its Product with
respect to ORTHO's approved Indications for ORTHO's Product (if ORTHO similarly
fails to accept subsequent ERGO proposals as provided in Article V).  At such
time, each Party shall submit to the other a written proposal for establishing
the allocation mechanism set forth in this Section 8.12 with respect to such
prospective Spillover Sales.  Such proposals shall be exchanged within thirty
(30) days following the date ORTHO declines ERGO's Section 5.04 proposal
referenced above.  In the event that the JPT is unable to agree upon such
mechanism based on the Party's respective proposals therefor within a ninety
(90) day period following the exchange of such proposals, then the matter shall
be referred to the Steering Committee for resolution.  If the Steering Committee
does not unanimously arrive at a resolution within ninety (90) days following
such referral, then the matter shall be resolved by an independent arbiter
mutually agreeable to both Parties, with such arbitration in any event being
concluded prior to the approval of the ERGO NDA for its Product.

                                  ARTICLE IX
                            MANUFACTURE AND SUPPLY
                            ----------------------

     SECTION 9.01.  Manufacture and Supply During Development. ORTHO will
                    -----------------------------------------            
arrange for the manufacture of Collaboration Products for use during the
Development of Collaboration Products as provided in this Agreement.  In this
regard, ORTHO and not ERGO shall be the Party to all manufacture agreements with
Third Parties for the supply of Collaboration Products during Development
Payments to manufacturers for such use and related costs will be a Development
Expense.  As used in this Article IX, "manufacture" means manufacture of
Collaboration Products in bulk form and finished dosage form.

     SECTION 9.02.  Manufacture and Supply During Commercialization.
                    ----------------------------------------------- 

     (a) ORTHO shall be solely responsible for the commercial manufacture of
Collaboration Products in such a manner as to achieve and maintain a
substantially competitive Cost of Goods Sold and to assure quality assurance as
stringent as such quality assurance standards used by ORTHO and its Affiliates
in the manufacture of its other pharmaceutical products, continuity and security
of supply, compliance with CGMP, and compliance with all applicable regulatory
requirements.  In this regard, ORTHO and not ERGO shall be the party to all
manufacture supply and development agreements covering the commercial supply of
Collaboration Products.  Such manufacturer(s) may include Third Parties.  To
enable the transfer of manufacturing to ERGO in situations under this Agreement
where ORTHO is obligated to do so, all contracts entered into by ORTHO with a
Third Party relating to the manufacturer of Collaboration Products shall include
a provision permitting the assignment of such contract to ERGO on the same terms
where possible for the remainder of such contract term.  If such a provision
adversely impacts the price offered, the Parties agree to discuss alternative
arrangements or contractual provisions.  Any selection of manufacturers for
Commercialization shall be subject to the rights of any Third Parties existing
at the time such determination is made.

     (b) ORTHO acknowledges that pursuant to that certain Amended and Restated
Supply Agreement, (the "Geneva Agreement") dated as of October 31, 1997, by and
between ERGO Research Corporation, ERGO Science Corporation, and Geneva
Pharmaceuticals, Inc. ("Geneva"), attached hereto as Exhibit F, Geneva will
manufacture Bromocriptine tablets in finished dosage form for worldwide

                                       41
<PAGE>
 
distribution for the period[*].  Pursuant to Section 11.05 of the Geneva
Agreement, ERGO hereby assigns to ORTHO, and ORTHO hereby accepts, all of ERGO's
rights and obligations under the Geneva Agreement. ORTHO agrees to pay [*]of the
payments to Geneva set forth in Sections 6.3 and 6.4 of the Geneva Agreement.
The payments set forth in Section 3.3 and 3.4 of the Geneva Agreement related to
the purchase of Bromocriptine tablets related to the Development and
Commercialization in the Profit/Loss Sharing Territory shall be Allowable
Expenses or Development Expenses, as appropriate (provided, however, that ORTHO
shall in no event be responsible for any expenses incurred prior to the
Effective Date and ERGO shall assume full responsibility for such expenses).
ORTHO and ERGO each agree to execute such other documents and instruments as may
be necessary to effectuate the assignment of rights and obligations under the
Geneva Agreement set forth in this Section 9.02(b).

     SECTION 9.03.  Quality Assurance, Etc.
                    ---------------------- 

     (a) ORTHO shall have day to day responsibility for commercial manufacturing
and formulation issues related to product safety and regulatory compliance.
ERGO shall provide technical support reasonably required by ORTHO or Third
Parties for the manufacture of Collaboration Products.  The costs of providing
on-going post-launch technical support shall be an Allowable Expense under Post-
Launch Product R & D Expense as defined in Exhibit A.  Regardless of the parties
selected to manufacture the Collaboration Products for the Profit/Loss Sharing
Territory, each of the Parties shall have rights of inspection and audit as set
forth in the contract with such Third Party to enable it to comply with its
internal quality assurance and reporting obligations, including those imposed by
regulatory authorities.  In addition, before a final commitment is made to any
Party or Parties or to any Third Party regarding manufacturing plant decisions
for the supply of Collaboration Products to the Profit/Loss Sharing Territory,
both Parties shall have the right to perform plant quality assurance audits.

     (b) All Collaboration Compounds and Products used in clinical and
commercial supplies will be manufactured, tested, and released according to
current CGMP's.  It is expected that the manufacturer will be responsible for
maintaining their facilities and procedures, including those of Third Parties,
in compliance with CGMP's.  ORTHO has the right to perform periodic assessments
of CGMP compliance by inspection of facilities for the manufacture of
Collaboration Compounds for use in clinical and commercial supplies, for the
manufacture of Collaboration products and active ingredients for use in clinical
and commercial supplies, and review of compliance related documents.  If CGMP
deficiencies should be identified by ORTHO, the manufacturer will receive
written notification from ORTHO describing the specific compliance issues
identified.  The manufacturer has an obligation to establish a corrective action
plan within 30 days of receiving notice of such deficiencies from ORTHO.  The
corrective action plan will establish clear goals and timing for improvement of
specific compliance issues and must be agreed to by ORTHO.  Any expenses
incurred in improving compliance will be the full responsibility of the
manufacture.  In the event that ORTHO's compliance assessment challenges the
suitability of any particular batch of clinical or commercial materials intended
for clinical or commercial use, ORTHO has the final decision regarding the
release of such materials.

     SECTION 9.04 Provisions for the Manufacture of Collaboration Products.  If
                  --------------------------------------------------------     
a Party is manufacturing and supplying the Collaboration Products, such Party
shall be entitled to recover as an Allowable Expense such Party's Cost of Goods
Sold for Collaboration Products so supplied, upon the sale of such Collaboration
Products according to its standard accounting procedures consistently applied
within and across its pharmaceutical operating units for matching revenues with
costs of products sold.  In the event a Party would obtain a tax benefit from
the manufacture of Collaboration Products in a particular jurisdiction, such tax
benefits shall be treated as described in Section 7.06 herein.

     SECTION 9.05 Technology Transfer in Event of Termination by ORTHO.  In the
                  ----------------------------------------------------         
event that, upon termination by ORTHO of this Agreement (other than a
termination under Section 14.02), ORTHO is manufacturing in whole or in part one
or more Collaboration Products or Royalty Bearing Products hereunder, then ORTHO
shall continue to provide for such manufacture of such Collaboration Products
and Royalty Bearing Products to the extent provided prior to notice of such
termination, from the time notice of such termination is provided until such
time as ERGO is able to secure an equivalent alternative commercial
manufacturing source, in the event that ERGO using its best efforts is unable to
secure such an alternative source during the notice period.  To this end, as of
the effective date of such termination all Third Party manufacturing contracts
shall be assigned to ERGO, and the cost charged to ERGO by ORTHO for any of the
internal manufacturing activities to be continued by ORTHO pursuant to this
Section 9.05 for the production of Collaboration Products and Royalty Bearing
Products shall be the same as ORTHO's cost during the time that the Agreement
was in effect, provided, however, ORTHO may begin to receive a profit for its
internal manufacturing activities relating to such Products at a rate of the
cost relating to such internal manufacturing activities plus [*]beginning one
(1) year after the effective date of termination hereunder and an additional
[*]for each additional year following the second anniversary of the effective
date of termination.  For example, during the third year following the effective
date of termination, the profit margin would be[*].  Further, upon ERGO's
request, ORTHO shall provide such technical assistance and Know-how licenses on
a royalty free basis as may reasonably be requested to transfer such technology
as needed by ERGO to commence or continue commercial manufacture of
Collaboration Products and Royalty Bearing Products.  Such technical assistance
shall be provided at ORTHO's cost, which cost shall be reimbursed by ERGO.  In
the event that any technology needed by ERGO to commence or continue commercial
manufacture of Collaboration Products or Royalty Bearing Products is covered by
one or more ORTHO Patents, ERGO shall receive a paid up, exclusive world-wide
right and license to such ORTHO patents as per Section 14.02 and Section 14.03.

     SECTION 9.06 Access to Geneva Know-How.  ORTHO, as assignee of the Geneva
                  -------------------------                                  
Agreement, shall have all rights to any manufacturing know-how that related to
manufacturing Bromocriptine, to the extent provided in the Geneva Agreement,
attached hereto as Exhibit F.

authorized by this Agreement or otherwise agreed in writing, the Parties agree
that, for the term of this Agreement and for [*]  thereafter, the receiving
Party shall keep confidential and shall not publish or otherwise disclose or use
for any purpose other than as provided for in this Agreement any Information and
other information and materials furnished to it by the other Party pursuant to
this Agreement or any Information developed during the course of the
collaboration hereunder, or any provisions of this Agreement that are the
subject of an effective order of the Securities Exchange Commission granting
confidential treatment pursuant to the Securities Act of 1934, as amended
(collectively, "Confidential Information"), except to the extent that it can be
               ---------------------------                                     
established by the receiving Party that such Confidential Information:

     (a) was already known to the receiving Party, other than under an
obligation of confidentiality, at the time of disclosure by the other Party;

     (b) was generally available to the public or otherwise part of the public
domain at the time of its disclosure to the receiving Party;

     (c) became generally available to the public or otherwise part of the
public domain after its disclosure and other than through any act or omission of
the receiving Party in breach of this Agreement;

                                       43
<PAGE>
 
     (d) was disclosed to the receiving Party, other than under an obligation of
confidentiality, by a Third Party who had no obligation to the disclosing Party
not to disclose such information to others; and

     (e) was independently developed by the receiving Party without reliance on
Confidential Information of the other Party.

     SECTION 10.02. Authorized Disclosure.  Each Party may disclose Confidential

Information hereunder to the extent such disclosure is reasonably necessary in
filing or prosecuting patent applications, prosecuting or defending litigation,
complying with applicable governmental regulations, or conducting pre-clinical
or clinical trials; provided, however, that if a Party is required by law or
regulation to make any such disclosures of the other Party's Confidential
Information it will, except where impracticable for necessary disclosures, for
example in the event of medical emergency, give reasonable advance notice to the
other Party of such disclosure requirement (e.g., filings with the SEC and stock
markets) and, except to the extent inappropriate in the case of patent
applications, will use its reasonable efforts to secure confidential treatment
of such Confidential Information required to be disclosed, unless in the opinion
of such disclosing Party's legal counsel such Confidential Information is
legally required to be fully disclosed.  In addition, and with prior notice to
the other Party of each Third Party with whom a confidential disclosure
agreement is being entered into, each Party shall be entitled to disclose, under
a binder of confidentiality containing provisions as protective as those of this
Article X, Confidential Information to any Third Party for the purpose of
carrying out the purposes of this Agreement.  Nothing in this Article X shall
restrict any Party from using for any purpose any Confidential Information
independently developed by it during the course of the collaboration hereunder,
or from using Confidential Information that is specifically derived from pre-
clinical or clinical trials to carry out marketing, sales or professional
services support functions as is customary in the pharmaceutical industry.

     SECTION 10.03. Survival.  Section 10.01 through 10.04 of this Article X
                    --------

the Confidentiality Agreements between ERGO and ORTHO dated as of October 28,
1996, and April 29, 1997.  All Information exchanged between the Parties under
that Agreement shall be deemed Confidential Information and shall be subject to
the terms of this Article X, and shall be included, respectively, within the
definitions of ERGO Know-how if ERGO is the disclosing Party and ORTHO Know-how
if ORTHO is the disclosing Party.

     SECTION 10.05. Publications.  Except to the extent set forth in Section
                    ------------                                            
10.02 and 10.06, each Party shall provide to the other the opportunity to review
any proposed publications or scientific presentations which relate to
Collaboration Compounds or Collaboration Products for Development Indications,
or Additional Indications, if any, as early as reasonably practical, but at
least thirty (30) days prior to the intended submission for publication (except
with the written consent of the other party).  The reviewing Party will provide
the publishing Party with its response to the publishing Party's request to
publish within thirty (30) days of receipt of such request.  No publication
shall be made by any Party without the agreement or approval in writing from the
other Party. However, the failure of the receiving Party to respond to such
request within such thirty (30) day period shall be deemed to be approval of
such request and the publishing Party shall then be free to proceed with said
publication or presentation. Notwithstanding the foregoing, publications
regarding Commercialization Activities or needed to effectively Commercialize
the Collaboration Product may be made by ORTHO even if ERGO does not 

                                       44

approve, provided that ORTHO can demonstrate that such publication is reasonably
necessary to successfully market the Product.

     SECTION 10.06. Public Announcements. Subject to the further provisions of

this Section 10.06, Parties, neither Party shall originate any written
publicity, news release or public announcement, whether to the public or press,
concerning this Agreement, including the subject matter to which it relates,
performance under it or any of its terms, or any amendment hereto save only such
announcements that are required by law to be made or that are otherwise agreed
by the Parties.  Such announcements shall be factual and as brief as possible.
In addition, each Party agrees to submit to the other Party, for review and
written approval any question and answer sheet or similar materials ("Q & A")
prior to using such materials as the basis for oral disclosures, which oral
disclosures must, in any event, be consistent in content with the information
contained in approved written materials.  Routine references to this Agreement
and the arrangements hereunder shall be allowed in the usual course of business,
subject to approved Q & A.  Once information has been approved for disclosure as
part of an approved Q & A under this Section 10.06, either party may use such
approved information in communications with Third Parties.  If a Party
decides to make an announcement required by law, it will give the other Party at
least [*]advance notice, where possible, of the text of the announcement so that
the other Party will have an opportunity to comment upon the announcement.  To
the extent that the receiving Party reasonably requests that any information in
the materials proposed to be disclosed be deleted, the disclosing Party shall
request confidential treatment of such information pursuant to Rule 406 of the
Securities Act of 1933 or Rule 25b-2 of the Securities Exchange Act of 1934, as
applicable (or any other applicable regulation relating to the confidential
treatment of information) so that there be omitted from the materials that are
publicly filed any information that the receiving Party reasonably requests to
be deleted, unless in the opinion of the disclosing Party's legal counsel such
Confidential Information is legally required to be fully disclosed.
Notwithstanding the foregoing, publications regarding Commercialization
Activities or needed to effectively Commercialize the Collaboration Product may
be made by ORTHO even if ERGO does not approve, provided ORTHO can demonstrate
such publication is necessary to successfully market the Product.[*]

     (a) Each Party, at its sole discretion and responsibility, shall prepare,
file, prosecute and maintain Patents to cover discoveries and inventions made
solely by its own employees or consultants relating to any Product and use
reasonable efforts to file initially all such applications in the United States
or the appropriate forum under the circumstances.  The JPT will determine which
Party shall file, prosecute and maintain Patents to cover inventions relating to
the discovery, evaluation, manufacture, use or sale of Collaboration Compounds
or Collaboration Products that are made jointly by personnel of ERGO and ORTHO
in the course of the collaboration (herein referred to as "Joint Patents").  The
determination of the countries in the Royalty Bearing Territory in which to file
Joint Patents shall be made by ORTHO. ORTHO shall have the right to direct and
control all material actions relating to the prosecution or maintenance of Joint
Patents in the Royalty Bearing Territory, and ERGO shall have the right to
request filing in countries not selected by ORTHO for filing provided that ERGO
shall pay all expenses associated therewith in such ERGO selected countries.
ORTHO shall provide prior written notice to ERGO of the countries in which it
intends to file in the Royalty Bearing Territory, including conflict
proceedings, reexaminations, reissuance, oppositions and revocation proceedings,
provided, however, that ERGO shall have the right to continue prosecution in
countries in which ORTHO determines it wishes to abandon.

     (b) The Party who is responsible for filing a Joint Patent will be termed
the "filing Party." The filing Party shall keep the other Party apprised of the
status of each Joint Patent and shall seek the advice of the other Party with
respect to patent strategy and drafting applications and shall give reasonable
consideration to any suggestions or recommendations of the other Party
concerning the preparation, filing, prosecution, maintenance and defense
thereof.  The Parties shall cooperate reasonably in the prosecution of all Joint
Patents and Patents covering Collaboration Products and shall share all material
information relating thereto, including all material communications from patent
offices, promptly after receipt of such information.  If the Parties are unable
to agree as to who is the filing Party or as to any aspect of patent prosecution
of a Joint Patent or a Patent covering a Collaboration Product, each Party at
its expense shall be free to take whatever action it deems appropriate to
protect the joint invention or Collaboration Product, including the filing of
patent applications subject to prior notification of the other Party.  If,
during the term of this Agreement, the filing Party intends to allow any Patent
covering a Product to which the Party has license rights under this Agreement to
lapse or become abandoned without having first filed a substitute, the filing
Party shall, whenever practicable, notify the other Party of such intention at
least sixty (60) days prior to the date upon which such Patent shall lapse or
become abandoned, and the other Party shall thereupon have the right, but not
the obligation, to assume responsibility for the prosecution, maintenance and
defense thereof and all expenses related thereto.  Where such other Party
assumes such responsibility, the affected patent shall not thereafter serve as a
basis for any royalty obligation otherwise payable by such Party to the other
Party.

     (c) The Parties agree to use reasonable efforts to ensure that any Patent
filed outside of the United States prior to a filing in the United States will
be in a form sufficient to establish the date of original filing as a priority
date for the purposes of a subsequent filing in the United States.

     (d) The Parties shall cooperate in order to avoid loss of any rights that
may otherwise be available to the Parties under the U.S. Drug Price Competition
and Patent Term Restoration Act of 1984, the Supplementary Certificate of
Protection of the Member States of the European Union and other similar measures
in any other country.  Without limiting the foregoing, either Party shall notify
the other Party promptly upon receipt of Regulatory Approval to market a
Collaboration Compound, Collaboration Product or Independent Product in the
United States, and timely supply such Party with all information necessary to
file an application for patent term extension for any relevant patent owned or
controlled by the Parties, within the sixty (60) day period following regulatory
Approval.  The obligations set forth in this Section 11.04(d) shall apply with
respect to patent term extensions, or the equivalent, in any other 

                                       46
<PAGE>
 
country. Any application for patent term extension in the United States shall be
made by the Party who owns or controls this patent to be term extended.

     SECTION 11.04. Third Party Patent Rights.  Except as expressly provided in
                    -------------------------                                  
Section 12.01, neither Party makes any warranty with respect to the validity,
perfection or dominance of any Patent or other proprietary right or with respect
to the absence of rights in Third Parties which may be infringed by the
manufacture or sale of any Product.  Each Party agrees to bring to the attention
of the other Party any Patent or Patent application it discovers, or has
discovered, and which relates to the subject matter of this Agreement.

     SECTION 11.05. Enforcement Rights.
                    ------------------ 

     (a) Notification of Infringement.  If either Party learns of any
         ----------------------------                                
infringement or threatened infringement by a Third Party of the ERGO Patents,
LSU Patents, ORTHO Patents, or Joint Patents, such Party shall promptly notify
the other Party and shall provide such other Party with all available evidence
of such infringement.

     (b) Enforcement in the Profit/Loss Sharing Territory.  The Steering
         ------------------------------------------------               
Committee will be fully apprised of the facts concerning the infringing acts,
and shall have an opportunity to comment and advise the Party that owns or
controls the infringed patent concerning in the appropriate course of action to
pursue with respect to infringement of any ERGO Patents, LSU Patent, ORTHO
Patents or Joint Patents covering the manufacture, use, importation, sale or
offer for sale of Collaboration Products being developed or marketed in the
Profit/Loss Sharing Territory.  The Party that owns or controls the infringed
patent shall control any enforcement thereof in the Profit/Loss Sharing
Territory.  Costs of patent enforcement and related recoveries with respect to
infringement in the Profit/Loss Sharing Territory shall be charged to the
collaboration as Allowable Operating Expenses. Each Party shall bear its own
expenses, with any recovery allocated pro rata to the extent of the Parties'
costs and any excess one-half to each of the Parties.

     (c) Enforcement for Royalty Bearing Products in the Royalty Bearing
         ---------------------------------------------------------------
Territory.  ERGO shall have the right, but not the obligation, to institute,

prosecute and control at its own expense any action or proceeding with respect
to infringement of any ERGO Patents, LSU Patents or Joint Patents covering the
manufacture, use, importation, sale or offer for sale of Collaboration Products
being developed or marketed in the Royalty Bearing Territory, by counsel of its
own choice.  ORTHO shall have the right, at its own expense, to be represented
in any action by counsel of its own choice.  If ERGO fails to bring an action or
proceeding or otherwise take appropriate action in ERGO's discretion to abate
such infringement within a period of [*]of notice by ORTHO to ERGO requesting
action, ORTHO will have the right but not the obligation to bring and control
any such action or proceeding relating to ERGO Patents or LSU Patents by counsel
of its own choice and ERGO will have the right to be represented in any such
action by counsel of its own choice and at its own expense. ERGO will cooperate
with ORTHO in any suit for infringement of an ERGO Patent or LSU Patent brought
by ORTHO against a Third Party, and shall have the right to consult with ORTHO
and to participate in and be represented by independent counsel in such
litigation at its own expense.  ORTHO shall incur no liability to ERGO as a
consequence of such litigation or any unfavorable decision resulting therefrom,
including any decision holding the infringed patent invalid or unenforceable. If
one Party brings any such action or proceeding, the other Party agrees to be
joined as a party plaintiff if necessary to prosecute the action or proceeding
and to give the first Party reasonable assistance and authority to file and
prosecute the suit.  Any damages or other monetary awards recovered pursuant to
this Section 11.05(c) shall be allocated first to the costs and expenses of the
Party bringing suit, then to the costs and expenses, if any, of the other Party.
Any amounts remaining shall go to the Party bringing suit.

                                       47
<PAGE>
 
     (d) Enforcement with Respect to Independent Products.  The Party developing
         ------------------------------------------------                       
or marketing an Independent Product shall have the right, but not the
obligation, to institute, prosecute and control at its own expense any action or
proceeding with respect to infringement of any ERGO Patents, LSU Patents, ORTHO
Patents or Joint Patents covering the manufacture, use, importation, sale or
offer for sale of an Independent Product being developed or marketed by such
Party, by counsel of its own choice.  The other Party shall have the right, at
its own expense, to be represented in any such action or proceeding within a
period of [*]of notice from the other Party requesting action, the other Party
will have the right to bring and control any such action or proceeding relating
to that Party's Patents (but not the Patents of the Party developing or
marketing such Independent Product) by counsel of its own choice and the Party
marketing the Independent Product will have the right to be represented in any
such action by counsel of its own choice and at its own expense.  If one Party
brings any such action or proceeding, the other Party agrees to be joined as a
party plaintiff if necessary to prosecute the action or proceeding and to give
the first Party reasonable assistance and authority to file and prosecute the
suit.  The Party bringing such action shall be entitled to retain any damages or
other monetary awards recovered pursuant to this Section 11.05 (d).

     (e) Settlement with a Third Party. The Party that controls the prosecution
         -----------------------------                                         
of a given action shall also have the right to control settlement of such
action; provided, however, that if one Party controls, no settlement shall be
        --------  -------

would materially and adversely affect the interests of such other Party.  If the
other Party shall refuse to grant such consent, then the dispute will be
resolved pursuant to Article XVI.

     (f) Exclusivity.  Notwithstanding the provisions of Sections 11.05(b), (c)
         -----------                                                           
and (d), neither Party shall file and prosecute an action for infringement of a
Patent in any country for which the other Party has the primary responsibility
to file and prosecute such action, and pursuant to which that other Party having
primary responsibility has commenced and is prosecuting at least one such action
for infringement of said Patent in the same country, without the agreement of
that other Party, which agreement shall not be unreasonably withheld or delayed.

     SECTION 11.06. Defense and Settlement of Third Party Claims.
                    -------------------------------------------- 

     (a) Defense in the Profit/Loss Sharing Territory.  If a Third Party asserts
         --------------------------------------------                           
that a patent, trademark or other intangible right owned by it is infringed by
any Collaboration Product in the Profit/Loss Sharing Territory, the Steering
Committee shall establish a plan for a common defense and select the Party
responsible for managing such plan.  The costs of any such action incurred by
one or both of the Parties at the direction of the Steering Committee (including
the costs of any judgment, award, decree or settlement) will be chargeable to
the collaboration as an Allowable Operating Expense.

     (b) Defense in the Royalty Bearing Territory.  If a Third Party asserts
         ----------------------------------------                           
that a patent, trademark or other intangible right owned by it is infringed by
any Royalty Bearing Product in the Royalty Bearing Territory, ORTHO will be
solely responsible for defending against any such assertions at its cost and
expense, but no settlement may be entered into without the written consent of
ERGO if such settlement would materially and adversely affect ERGO's interests.

     (d) Settlement with a Third Party. The entity that controls the defense of
         -----------------------------                                         
a given claim with respect to a Collaboration Product shall also have the right
to control settlement of such claim; provided, however, that other than as
                                     --------                             
provided in Section 11.06(b), no settlement shall be entered into without the
written consent of the other Party, which consent shall not be unreasonably
withheld or delayed.  If there is no agreement between the Parties as to any
proposed settlement, then the dispute shall be decided by 

                                       48

the Steering Committee, and, if the Steering Committee is unable to decide the
dispute, the matter will be resolved pursuant to Article XIV.

     SECTION 11.07. Patent Expenses.
                    --------------- 

     (a) From the Effective Date of this Agreement prior to the first commercial
sale of a Collaboration Product, all Patent Expenses in the Profit/Loss Sharing
Territory related to such Collaboration Product will be treated as Development
Expenses.

     (b) Following the first commercial sale of a collaboration Product, all
Patent Expenses arising in the Profit/Loss Sharing Territory related to such
Collaboration Product shall be treated as Allowable Operating Expenses.

     (c) On a country-by-country basis, Patent Expenses arising from ERGO
Patents and LSU Patents in the Royalty Bearing Territory shall be born by ERGO,
and Patent Expenses arising from ORTHO Patents and Joint Patents in the Royalty
Bearing Territory shall be borne by ORTHO.

     SECTION 11.08. Assignment of Joint Patents.  Neither Party may assign its
                    ---------------------------                               
rights under any Joint Patent except with the prior written consent of the other
Party; provided, however, that either Party may assign such rights without
       --------                                                           
consent to an Affiliate or other permitted assignee under this Agreement in
connection with a merger or similar reorganization or the sale of all or
substantially all of its assets, as provided for in Section 17.01(b).

     SECTION 11.09. Trademarks and Trademark Expenses.  ORTHO and ERGO shall
                    ---------------------------------
equally share the expenses for the selection, registration and maintenance of
all trademarks which are employed in connection with the sale of Collaboration
Products in the Profit/Loss Sharing Territory. ERGO agrees that ORTHO shall not
be required to use the trademark ERGOSET(TM) in association with any
Collaboration Product or Independent Product, and that ERGO shall not use the
trademark ERGOSET(TM) in association with any Collaboration Compound, any
Collaboration Product or Independent Product unless this Agreement is terminated
by ORTHO or the marks adopted by ORTHO for Collaboration Products do not
encompass any mark that is confusingly similar to ERGOSET. ORTHO shall be solely
responsible for the selection, registration, and maintenance of all trademarks
which it employs in connection with the marketing, promotion and sale of
Collaboration Product(s) and shall solely own and control such trademarks. ORTHO
shall keep the JPT informed of proposed trademark development and Trademark
Expenses in connection with the trademarks to be used in the Profit/Loss Sharing
Territory. Each Party recognizes the exclusive ownership by the other Party of
any proprietary names, logotypes or trademarks furnished by it (including its
Affiliates) for use exclusively in connection with Collaboration Products.
Either Party shall not, either while this Agreement is in effect, or at any time
thereafter, register, use or attempt to obtain any right in or to any such name,
logotype or trademark or in and to any name, logotype or trademark confusingly
similar thereto. In the event that this Agreement is terminated by ERGO pursuant
to Section 14, then, at ERGO's option, ORTHO shall license to ERGO, on a royalty
free basis, any trademark specifically developed for the Collaboration
Product(s).

     (a) Each of the Parties hereby represents and warrants to the other Party
as follows:

                                       49
<PAGE>
 
          (i) This Agreement is a legal and valid obligation binding upon such
Party and enforceable in accordance with its terms.  The execution, delivery and
performance of the Agreement by such Party does not conflict with any agreement,
instrument or understanding, oral or written, to which it is a Party or by which
it is bound, nor violate any law or regulation of any court, governmental body
or administrative or other agency having jurisdiction over it.  Each Party
expressly represents and warrants that it has the full power and authority to
enter into this Agreement and to carry out the obligations contemplated hereby.

          (ii) Such Party has not, and during the term of the Agreement will
not, grant any right to any Third Party relating to its respective Patents and
Know-how in the Field which would conflict with the rights granted to the other
Party hereunder.

          (iii) To the best of its knowledge ERGO is obligated under one
agreement as of the Effective Date to pay Third Parties royalties with respect
to Bromocriptine and any other Collaboration Products for Metabolic Indications;
provided, however that ERGO is obligated for certain time periods to make
payments to certain parties as a result of litigation prior to the Effective
Date (the "Martin and Filler Litigation"), as set forth in ERGO's SEC filings.
ERGO shall be responsible for making any and all payments as a result of the
Martin and Filler Litigation and such payments shall not be considered Allowable
Expenses.  ORTHO agrees to make reasonable efforts to provide an accounting to
ERGO for sales of Collaboration Products in the states of Texas and California.
As of the Effective Date the only agreement to pay royalties to a Third Party on
sales of Bromocriptine for Metabolic Indications is the LSU Agreement.   There
is currently one other agreement related to the use of Bromocriptine for the
treatment of Non-Metabolic Diseases with the General Hospital Corporation, as
set forth in ERGO's SEC filings.

     (b) ERGO hereby represents and warrants to ORTHO as follows:

          (i) It has as of the Effective Date given ORTHO access to all clinical
records that describe all adverse event reports related to Collaboration
Products including those that have been filed with the FDA prior to the
Effective Date.

          (ii) As of the Effective Date, except as it may have previously
disclosed to ORTHO in writing, it has not received any notices of infringement
or any written communications relating in any way to a possible infringement
with respect to Bromocriptine, and that it is not aware that the manufacture,
use or sale of Bromocriptine or Ergoset tablets as set forth herein infringes
any Third Party patent rights which have not been licensed to ERGO.

          (iii) ERGO expressly represents and warrants that it has brought to
ORTHO's attention any Third Party Patents of which it is aware is of the
Effective Date, which are relevant to the manufacture use or sale of
Bromocriptine and/or Ergoset tablets.

          (iv) ERGO expressly represents and warrants that it has the full power
and authority to enter into this Agreement and to carry out the obligations
contemplated hereby.  ERGO expressly represents and warrants that it owns (in
whole or in part) or Controls all Patents and Know-how that are the subject of
the licenses granted to ORTHO herein.

     (c) Each Party acknowledges that the other Party is, or in the future may
be, Developing and/or Commercializing or acquiring a variety of products in a
variety of fields including but not limited to the field of diabetes and
obesity.

each Party shall remain responsible for and be a guarantor of the performance by
its Affiliates and shall cause its Affiliates to comply with the provisions of
this Agreement in connection with such performance.

     (b) Johnson & Johnson hereby guarantees the performance of ORTHO and the
Affiliates of ORTHO under this Agreement and the Stock Purchase Agreement and
hereby expressly waives any requirement that ERGO exhaust any right, power or
remedy or proceed against ORTHO or the Affiliates of ORTHO for any obligation or
performance hereunder or thereunder.

complaints it receives with respect to any Collaboration Product.  Each Party
shall notify the other Party of any complaint with regulatory implications
received by it in sufficient detail and within five (5) business days after the
event, and in any event in sufficient time to allow the responsible Party to

     SECTION 13.03. Adverse Drug Experiences.  The Parties recognize that the
                    ------------------------                                 
holder of a Drug Approval Application may be required to submit information and
file reports to various governmental agencies on Collaboration Products under
clinical investigation, Collaboration Products proposed for marketing, or
marketed Collaboration Products.  Information must be submitted at the time of
initial filing for investigational use in humans and at the time of a request
for market approval of a new Collaboration Product.  In addition, supplemental
information must be provided on Collaboration Products at periodic intervals and
adverse drug experiences must be reported at more frequent intervals depending
on the severity of the experience and whether or not the event is unexpected.
Consequently, each Party agrees to:

<PAGE>
 
     (a) Provide to the other for their use in making initial and/or periodic
submissions to government agencies significant information on the Collaboration
Product from preclinical laboratory, animal toxicology and pharmacology studies,
as well as adverse drug experience reports from clinical trials and commercial
experiences with the Collaboration Product;

     (b) In connection with investigational Collaboration Compounds, report to
the other within three (3) days of the initial receipt of a report of any
serious experience with the drug, if required for either Party to comply with
regulatory requirements; each party will also provide to the other within one
(1) month, copies of any safety submission (e.g. IND expedited reports or annual
reports) submitted to any regulatory agencies and

     (c) In connection with marketed Collaboration Products, each party will
send to the other within one (1) month, copies of any single or periodic safety
submissions filed with regulatory agencies, e.g., 15 day expedited reports,
annual updates, etc.

     (d) If it contracts with a Third Party for research to be performed by such
Third Party on the drug, the contracting Party agrees to require such Third
Party to report to the contracting Party the information set forth in
subparagraphs (a), (b), and (c) above.  The Parties agree that at all times
after the approval of any Drug Approval Application or equivalent thereof, ORTHO
shall be responsible for collecting, collating and reporting to the appropriate
regulatory authority all adverse drug experiences.

records shall be open during reasonable business hours for a period of three (3)
years from creation of individual records for examination at the other Party's
expense and not more often than once each year by a certified public accountant
selected by the other Party for the sole purpose of verifying for the inspecting
Party the correctness of calculations and classifications of such revenues,
costs, expenses or payments made under this Agreement.  In the absence of
material discrepancies (in excess of [*]of Operating Profits or Losses or the
royalties payable under this Agreement) in any request for reimbursement
resulting from such audit, the accounting expense shall be paid by the Party

                             TERM AND TERMINATION
                             --------------------

     SECTION 14.01. Term.  This Agreement shall commence as of the Effective
                    ----                                                    
Date and, unless sooner terminated as provided herein, (a) the provisions
relating to Development and Commercialization in the Profit/Loss Sharing
Territory shall continue in effect until the Parties are not Developing or
Commercializing any Collaboration Compounds or Collaboration Products within
such territory; and (b) the provisions relating to Commercialization of Royalty
Bearing Products and Independent Products shall continue in effect until the
date on which neither Party is obligated to pay a royalty to the other Party on
Royalty Bearing Sales of Royalty Bearing Products or Independent Products.

     SECTION 14.02. Termination for Material Breach.
                    ------------------------------- 

     (a) Subject to the provisions of this Section 14.02, if either Party (the
"Breaching Party") shall have committed a Material Breach and such Material
Breach shall remain uncured and shall be continuing for a period of one hundred
twenty (120) days following receipt of notice thereof by the other Party (the
"Non-Breaching Party"), then, in addition to any and all other rights and
remedies that may be available, the Non-Breaching Party shall have the right to
terminate this Agreement effective upon the expiration of such one hundred
twenty (120) day period.  Any such notice of alleged Material Breach by one
party (the "Accusing Party") shall include a reasonably detailed description of
all relevant facts and circumstances demonstrating, supporting and/or relating
to each such alleged Material Breach by the other party ("Accused Breaching
Party).

     (b) If the Accused Breaching Party, upon written notice delivered to the
Accusing Party prior to the expiration of such one hundred twenty (120) day
period, shall assert in good faith that any such alleged Material Breach
described in the Accusing Party's notice, whether in payment of moneys or
otherwise, was not a Material Breach, or was excused by reason of material
failure of performance by the other Party or Third Parties or by reason of Force
Majeure (as defined in Section 17.05), or shall otherwise in good faith dispute
such alleged Material Breach, then the Parties shall continue to perform under
this Agreement, subject to all of its terms and conditions, and the matter shall
be resolved pursuant to the provisions of Sections 16.02 and 16.03. In such
event, the Accusing Party shall not be entitled to terminate this Agreement
pursuant to this Section 14.02 unless and until (i) it shall be determined
pursuant to Sections 16.02 and 16.03 that the Accused Breaching Party has
committed a Material Breach and (ii) such Material Breach has not been cured
prior to such determination pursuant to Sections 16.02 and 16.03. To the extent
that it is determined pursuant to a final and non-appealable decision under
Sections 16.02 and 16.03 that the Accused Breaching Party did commit a Material
Breach and failed to 

                                       53
<PAGE>
 
cure the same within the period provided for in clause (ii) above, then the
Accusing Party may immediately terminate this Agreement and, in addition to all
damages determined pursuant to the provisions of Sections 16.02 and 16.03 to be
due and owing from the Breaching Party to the Non-Breaching Party under this
Agreement, the Breaching Party shall be liable for the Non-Breaching Party's
reasonable attorneys' fees incurred in connection with resolving such matter
pursuant to Sections 16.02 and 16.03.

     (c) If the Non-Breaching Party terminates this Agreement pursuant to the
provisions of this Section 14.02(a) and (b), then the following provisions shall
apply:

          (i)   The Non-Breaching Party shall receive an exclusive (even as to
the Breaching Party), worldwide right and license, with the right to grant
sublicenses, to all Patents of the Breaching Party as of the date of termination
to the extent that such licenses are necessary to make, have made, import, use,
sell, offer for sale and have sold Collaboration Products and Royalty Bearing
Products and Independent Products for the Indications then being Developed or
Commercialized and shall have the exclusive right (but not the obligation),
subject to the rights of Third Parties existing prior to the Effective Date to
enforce such Patents against competitive product infringement (in the manner
contemplated under the terms of Section 11.05 applicable to Patents of the
Breaching Party in the event that the Breaching Party does not or will not so
enforce the Patents) and the exclusive right (but not the obligation) to enforce
such trademark rights against infringers;

          (ii)  If ORTHO is the Non-Breaching Party, the Profit/Loss Sharing
Territory shall be converted to a Royalty Bearing Territory with Royalty
Percentages of[*].

          (iii) all licenses and rights to the Non-Breaching Party's patents,
trademarks, and know-how granted to the Breaching Party hereunder shall
terminate;

          (iv)  all Confidential Information supplied by the Non-Breaching Party
to the Breaching Party shall be returned to the Non-Breaching Party except the
Breaching Party may retain one copy of such information solely for legal archive
purposes;

          (v)   the Breaching Party shall promptly transfer or assign its
ownership of IND's, Drug Approval Applications and Regulatory Approvals related
to Collaboration Compounds, Collaboration Products, and Royalty Bearing Products
to the Non-Breaching Party, and shall take such other actions and execute such
other instruments, assignments and documents as may be necessary to effect the
transfer of rights hereunder to the Non-Breaching Party; and

          (vi)  the Breaching Party shall assign all of its rights in and to all
Joint Patents and licensed Third Party Patents provided that the Breaching Party
has the right to assign or sublicense such rights (and all registrations and
applications for registration therefor) to the Non-Breaching Party.

     (d) In the event of termination of this Agreement pursuant to this Section
14.02 where the Breaching Party is the Manufacturing Party with respect to one
or more Collaboration Products hereunder, the Manufacturing Party shall continue
to provide for manufacture of such Collaboration Products to the extent provided
prior to notice of such termination, from the effective date of such termination
until such time as the Non-Manufacturing Party is able to secure an equivalent
alternative commercial manufacturing source, as requested by the Non-
Manufacturing Party, provided, however, that said period shall cease after [*]
                     --------                                                 
from the effective date of the termination.  To this end, as of the effective
date of such termination, all Third Party manufacturing contracts shall, as
requested by the Non-Manufacturing Party, be assigned to the Non-Manufacturing
Party, and the cost charged to the Non-

                                       54
<PAGE>
 
Manufacturing Party by the Manufacturing Party for any of the internal
manufacturing activities to be continued by the Manufacturing Party pursuant to
this Section 14.02 for the production of Collaboration Products shall be the
same as the Manufacturing Party's cost was while this Agreement was in effect.
Further, upon the request of the Non-Manufacturing Party, the Manufacturing
Party shall provide such technical assistance and know-how licenses on a 
royalty-free basis as may reasonably be requested to transfer such technology as
is needed by the Non-Manufacturing Party, to commence or continue commercial
manufacture of Collaboration Products. Such technical assistance shall be
provided at the Manufacturing Party's cost, which cost shall be reimbursed
within thirty (30) days upon receipt of an invoice from the Manufacturing Party
by the Non-Manufacturing Party or its designee. In the event that any technology
as is needed by the Non-Manufacturing Party to commence or continue commercial
manufacture of Collaboration Products is covered by one or more Patents owned or
Controlled by the Manufacturing Party, the Non-Manufacturing Party shall receive
a fully paid-up, royalty-free, non-exclusive worldwide license to practice any
and all such Patents for the purposes contemplated in this Section 14.02, with
the right to grant sublicenses.

     (e) Except where expressly provided for otherwise in this Agreement,
termination of this Agreement shall not relieve the Parties hereto of any
liability, including any obligation to make payments hereunder, which accrued
hereunder prior to the effective date of such termination, nor preclude any
Party from pursuing all rights and remedies it may have hereunder or at law or
in equity with respect to any breach of this Agreement nor prejudice any Party's
right to obtain performance of any obligation.

     (f) For purposes of this Agreement and except as expressly provided
otherwise in this Agreement, "Material Breach" means the breach of or failure to
perform, in a material respect, a Party's material obligations under this
Agreement. Without limiting the foregoing and by way of example only, the term
"Material Breach" shall be deemed to include the failure of any Party in a
material respect to meet such Party's payment obligations under Articles III,
IV, V, VII and VIII (provided, however, that default by ERGO of its payment
obligations pursuant to Section 4.08 and Section 8.02 shall not be a material
breach of this Agreement); and the election of a Party to proceed with
Development or Commercialization of a Collaboration Compound in violation of its
rights and obligations under Article V.  In no event shall an inadvertent
failure to comply with the provisions of Section 10.05 or the failure to gain
Regulatory Approval for a Collaboration Product or to meet timelines or budgets
specified in any Development Plan, Development Budget, Commercialization Plan,
Commercialization Budget, Launch Plan or Launch Budget, in and of itself, be
deemed to constitute a Material Breach, unless such failure is a result of acts
and events or conduct that is otherwise a Material Breach.  The Parties
acknowledge and agree that failure to exercise any right or option with respect
to any Product shall not be deemed to constitute a Material Breach hereunder.
 
     (g) The provisions of this Section 14.02 shall survive termination of this
Agreement.

     SECTION 14.03. Termination by ORTHO.
                    -------------------- 

     (a) ORTHO shall have the right to terminate this Agreement upon thirty (30)
days advance written notice to ERGO and without any termination fee in the event
that after the Effective Date: (i) issues regarding the Safety of Bromocriptine
arise during the Development or Commercialization of Bromocriptine for a Type II
Diabetes Indication that indicate a materially and adversely different Safety
profile of Bromocriptine existing as of the Effective Date as evidenced in

payable to ERGO if the reason for termination is a materially adverse change in
Safety or Tolerability of said Collaboration Product or there is a materially
adverse regulatory development, [*]; or

          (ii) after[*], upon [*] prior written notice, without payment of any
termination fee.

     SECTION 14.04. Effect of Termination by ORTHO Pursuant to Section 14.03. If

ORTHO terminates this Agreement pursuant to Section 14.03, it shall continue to
be obligated during the termination notice period to perform all of its

achieved during the termination notice period.  In addition, as a result of such
termination:

     (a) ERGO shall receive a fully paid up, exclusive (even as to ORTHO but
subject to rights of Third Parties that are not Affiliates of ORTHO that pre-
existed or accrued prior to such termination notice) worldwide right and
license, with the right to grant sublicenses, to all ORTHO Patents and
Trademarks, being used at the time of termination to make, have made, import,
use, sell, offer for sale and have sold Collaboration Products and Independent
Products, subject to the applicable royalty obligations set forth in this
Agreement, and shall have the right (but not the obligation) to enforce the
ORTHO Patents against competitive product infringement (in the manner
contemplated under and pursuant to the terms of Section 11.05 applicable to
ORTHO Patents in the event that ORTHO does not or will not so enforce the
Patents) and the exclusive right (but not the obligation) to enforce the
trademark rights against infringers;

     (b) all licenses and rights to ERGO Patents and Trademarks and LSU Patents
and ERGO Know-how granted to ORTHO hereunder shall terminate;

     (c) all Confidential Information supplied by ERGO to ORTHO shall be

take such other actions and execute such other instruments, assignments and
documents as may be necessary to effect the transfer of rights hereunder to
ERGO; and

     (f) ORTHO shall assign all of its rights in and to all Joint Patents to
ERGO.

matters may from time to time arise during the term of this Agreement or the
Stock Purchase Agreement that relate to either Party's rights and/or obligations
hereunder or thereunder.  It is the objective of the Parties to establish
procedures to facilitate the resolution of disputes arising under this Agreement
or the Stock Purchase Agreement in an expedient manner by mutual cooperation and
without resort to litigation.  To accomplish this objective, the Parties agree
to follow the procedures set forth in this Article XVI if and when a dispute
arises under this Agreement or the Stock Purchase Agreement.

     Unless otherwise specifically recited in this Agreement, disputes between
the Parties shall be first referred to the Steering Committee by either Party at
any time after such dispute has arisen and such Party believes that there has
been sufficient discussion of the matter at the JPT level, as the case may be.
If the Steering Committee is unable to resolve such a dispute within thirty (30)
days of being requested by a Party to resolve such dispute, any Party may, by
written notice to the other, have such dispute referred to their respective
executive officers designated below or their successors, for attempted
resolution by negotiations within fourteen (14) days after such notice is
received.  Said designated officers are as follows:

For ORTHO:
 
The Executive Committee member of J&J who has responsibility for the business
units responsible for diabetes treatments.

For ERGO:
Chief Executive Officer

          In the event the designated executive officers are not able to resolve
such dispute, other than those disputes which may be expressly prohibited from
being resolved by this mechanism such as the Excepted Development Matters
referred to in Section 2.04 hereof, either Party may at any time after the
fourteen (14) day period seek to resolve the dispute through other means as

breach or to termination of this Agreement, but excluding (i) any dispute,
controversy or claim arising out of or relating to the validity, enforceability,
or infringement of any ERGO Patent or any ORTHO Patent and (ii) other than
disputes which are expressly prohibited herein from being resolved by this
mechanism, shall be settled by binding Alternative Dispute Resolution ("ADR") in
the manner described below:


                                      59

     (a)  If a Party intends to begin an ADR to resolve a dispute, such Party
shall provide written notice (the "ADR Request") to counsel for the other Party
                                  --------------                               
informing such other Party of such intention and the issues to be resolved.
From the date of the ADR Request and until such time as any matter has been
finally settled by ADR, the running of the time periods contained in Section
14.02 as to which a Party must cure a breach of this Agreement shall be

     SECTION 16.03. Arbitration Procedures.  An ADR initiated under this
                    ----------------------                              
Agreement will proceed in accordance with the Commercial Arbitration Rules of
the American Arbitration Association for Large, Complex Cases then in effect,
insofar as such rules are not inconsistent with the provisions expressly set
forth in this Agreement, unless the Parties mutually agree otherwise, and
pursuant to the following procedures:

     (a)  Arbitrators. The arbitration shall be carried out by a panel of three
(3) each of whom shall be a retired United States judge or justice and shall be
selected by the Parties within thirty (30) days of receipt of the ADR request in
accordance with the procedure described below.

          (i)   The Parties shall select the arbitrators as described in Section
16.03(a)(ii) below, which arbitrators may but need not be selected from a list
of arbitrators such as the CPR Panel of Distinguished Neutrals of the Center for
Public Resources, subject to: (1) his/her availability and willingness to serve,
(2) his/her availability to commence the arbitration within a reasonable period
of time, (3) his/her agreement to charge fees and expenses that are reasonable
under the circumstances, and (4) his/her commitment to render his/her award
within the time periods provided in this Section 16.03.

          (ii)  Each Party will exchange a list of ten (10) qualified
arbitrators and in the event that both Parties agree on all three persons then
those persons shall be the arbitrators. In submitting the ten names, each Party
shall prioritize from one to ten the persons on their respective lists. In the
event that there is more than one common name on the Parties' lists, the person
having the lowest combined priority number shall be selected as an arbitrator.
The combined priority number shall be the sum of the order numbers assigned to
that person by the Parties. Thus, if one person was ERGO's number two priority
and ORTHO's number three priority, and another person was ERGO's number two
priority and ORTHO's number four priority, the former would be appointed. If
more than one person has the lowest combined priority number, the person for
whom there is less difference between the order numbers assigned by the Parties
shall be appointed. Thus, if one person was ERGO's number one priority and
ORTHO's number four priority, and another person was ERGO's number two priority
and ORTHO's number three priority, the latter person would be appointed. If this
method does not produce three arbitrators, or if there are no common names, the
Parties shall alternatively strike from the combined list until three names,
which shall be the selected arbitrators. The Party to strike first shall be
determined by the toss of a coin.

          (iii) In the event the arbitrators are unable to meet the requirements
set forth in (i) above, then, in the event the first selected arbitrators were
common to both lists and there were more than three common names on the Parties'
lists, the arbitrator having the next lowest combined priority number who is
able and willing to serve pursuant to these requirements shall be selected. If
there is no such individual, then the Parties shall use the alternate strike
method set forth above. In the event an arbitrator selected by the alternate
strike methodology is unable or unwilling to serve consistent with the


                                      60
<PAGE>
 
requirements set forth above, then the alternate striking procedure shall be
retraced in reverse order until the arbitrators are selected.

     The arbitrators shall be neutral, disinterested, impartial, and independent
of the Parties and others having any known interest in the outcome, and shall
abide by the AAA/ABA Code of Ethics for Arbitrators in Commercial Disputes.
There shall be no ex parte communications with the arbitrators either before or
during the arbitration, relating to the dispute or issues involved in the
dispute or the arbitrator's views on any such issue.

     (b)  Interim Review.  Either Party may apply to any court having
jurisdiction hereof and seek preliminary injunctive relief until such time as
the arbitration award is rendered or the controversy is otherwise resolved.

     (c)  Location.  Any arbitration under this Section 16.03 shall be conducted
in New York, NY.

     (d)  Discovery Proceedings.  The Parties shall have the right to undertake
complete discovery, as contemplated by and pursuant to Rules 26-37 of the
Federal Rules of Civil Procedure (with references to "court" in those Rules
being considered references to the "arbitrator") except as they may be modified
by the following:

     Within fourteen (14) days after selection of the arbitrators, each Party
may serve on any other Party (i) interrogatories for the purpose of
identification of documents and witnesses, (ii) requests for admissions, and
(iii) requests for the production of documents and things.  These discovery
requests will be answered within fourteen (14) days of receipt.

     At any time but not more than six (6) months after the selection of the
arbitrators, each Party may take depositions of an opposing Party as a matter of
right.  The Parties will attempt to agree to time, location, and duration of the
deposition, and if the Parties do not agree these will be determined by the
arbitrators.

     Any Party may conduct depositions of its own witnesses which may be
introduced as evidence at the arbitration hearing if the other Party was given
fair opportunity to attend the deposition and cross-examine.

     As they become aware of new documents or information, including experts who
may be called upon to testify, all Parties remain under a continuing obligation
to provide documents upon which they rely, to supplement their responses, and to
honor any informal agreements or understandings between the Parties regarding
documents or information to be exchanged.  The arbitrators at the hearing will
not consider documents that have not been previously exchanged, unless agreed by
the Parties.

     The Parties will promptly notify the arbitrators when an unresolved dispute
exists regarding discovery issues.  The arbitrators will discuss the matter with
the Parties to determine the nature of the dispute and will attempt to resolve
that dispute. If the arbitrators do not resolve the dispute, the arbitrators
will arrange a conference concerning the dispute before the arbitrators by
telephone, or in person, and the arbitrators will decide the dispute.

     All discovery shall be completed within six (6) months from selection of
the arbitrators, unless extended by agreement of the Parties or by the
arbitrators for good cause shown.


                                      61
<PAGE>
 
     The arbitrators will determine the specific location within New York, NY
and the date and time of the arbitration hearing(s) and other proceedings after
consultation with the arbitrators and the Parties and will provide reasonable
notice of the hearing(s) date and time.  The arbitrators will make every effort
to schedule the arbitration hearing within ninety (90) days of the completion of
all discovery, absent unusual circumstances.

     The Parties may mutually agree on or the arbitrators for good cause may
order a rescheduling of the hearing date.

     The arbitrators will ordinarily conduct the arbitration hearing in the
manner set forth in this Section 16.3 except that (i) the Federal Rules of
Evidence shall apply and (ii) the arbitrators shall render their decision in
writing in the manner provided by Rule 52 of the Federal Rules of Civil
Procedure, including a full and precise statement of the factual and legal bases
for such decision.  If the AAA rules and the rules of this Section 16.03(d)
conflict in any manner, the rules of this Section 16.03(d) shall prevail.  The
arbitrators must hold an oral hearing, but may impose reasonable time limits on
each phase of the proceeding and may limit testimony to exclude evidence that
would be immaterial or unduly repetitive, provided that all Parties are afforded
the opportunity to present material and relevant evidence and that each Party is
given at least an approximately equal amount of time for presentation of its
case.

     Written briefs may be filed up to five (5) days before the hearing.

     The arbitrators will require witnesses to testify under oath if requested
by any Party.

     Any Party desiring a stenographic record may secure a court reporter to
attend the proceedings.

     The arbitrators will determine the order of proof, which will generally be
similar to that of a court trial, including opening and closing statements.

     When the arbitrators determine that all relevant and material evidence and
arguments have been presented, the arbitrators will declare the hearing closed.
The arbitrators may defer the closing of the hearing for up to twenty (20) days
to permit the Parties to submit post-hearing briefs and or to make closing
arguments, as the arbitrators deem appropriate, before rendering an award.

     The arbitrators will render the award and its decisions pursuant to Fed. R.
Civ. P. 52 within thirty (30) days after the date of the closing of the hearing
or, if an arbitration hearing has been waived, within thirty (30) days after the
date of the arbitrator's receiving all materials specified by the Parties.  The
decision and award of the arbitrators will constitute the Arbitration Award and
will be binding on the Parties.

     The arbitrators shall, in rendering their decision and award, apply the
substantive law of the State of New York, without regard to its conflict of laws
provisions, except that the interpretation of and enforcement of this Article
shall be governed by the Federal Arbitration Act.  The costs of the winning
Party and the fees of the arbitrators shall be paid by the losing Party as
determined by the arbitrators.  If the arbitrators are unable to designate a
losing party, it shall so state and each Party shall bear its own costs and the
fees of the arbitrators shall be split equally between the Parties.

     (e)  Award.  The arbitrators are empowered to award any remedy allowed by
law, including money damages, prejudgment interest and attorneys' fees, and to
grant final, complete, interim, or interlocutory relief, including injunctive
relief.  Notwithstanding the foregoing, punitive or multiple damages may not be
awarded.


                                      62
<PAGE>
 
     (f)  Legal Fees.  Except as set forth in Paragraph 16.03(e) above, each
Party shall bear its own legal fees.

     (g)  Confidentiality.  The ADR proceeding shall be confidential and the
arbitrator shall issue appropriate protective orders to safeguard each Party's
Confidential Information.  Except as required by law, no Party shall make (or
instruct the arbitrator to make) any public announcement with respect to the
proceedings or decision of the arbitrator without prior written consent of each
other Party.  The existence of any dispute submitted to ADR, and the award,
shall be kept in confidence by the Parties and the arbitrator, except as
required in connection with the enforcement of such award or as otherwise
required by applicable law.

     SECTION 16.04. Survivability.  Any duty to arbitrate under this Agreement
                    -------------

agree to accept the jurisdiction of any court having jurisdiction over the
Parties for the purposes of enforcing awards entered pursuant to this Article
and for enforcing the agreements reflected in this Article.

                           STOCK PURCHASE AGREEMENT


     This STOCK PURCHASE AGREEMENT (the "Agreement") is made as of February 23,
1998, by and between Ergo Science Corporation, a Delaware corporation (the
"Company"), and Johnson & Johnson Development Corporation, a New Jersey
corporation ("JJDC").

                                   RECITAL:


     WHEREAS, JJDC desires to purchase from the Company, and the Company desires
to sell to JJDC, shares of the Company's common stock, upon the terms and
subject to the conditions set forth herein and in connection with the execution
of a separate Joint Collaboration and License Agreement (the "License
Agreement") of even date herewith between Ortho-McNeil Pharmaceutical
Corporation ("Ortho") and the Company.

     NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein, the parties hereto agree as follows:

          1. Purchase and Sale of Shares.  (a)  Subject to the terms and 
             ---------------------------                                 
conditions of this Agreement, at the Closing (as defined hereinafter), the
Company agrees to sell to JJDC and JJDC agrees to purchase from the Company,
that number of shares (the "Shares") of the Company's Common Stock, par value
$.01 (the "Common Stock"), determined by dividing ten million dollars
($10,000,000) by the Share Price (as defined below), for an aggregate purchase
price (the "Purchase Price") of ten million dollars ($10,000,000). For the
purposes hereof, "Share Price" shall mean the arithmetic average of the closing
prices of the Common Stock, as reported by the NASDAQ National Market System
("Nasdaq") or such other principal securities exchange or market on which the
Common Stock is then traded, for the period commencing ten (10) trading days
prior to and ending as of the date which is ten (10) trading days after the date
hereof; provided, however, that in the event that the Common Stock is not traded
        --------  -------
on any trading day during such period, then the closing price of the Common
Stock on such day shall be deemed to be the closing price of the most recent
previous trading day on which the Common Stock was traded on such exchange or
market.

          (b)  The purchase and sale of the Shares shall take place at the
offices of the Company, at 10:00 a.m. Eastern time on such date (the "Closing
Date") as the parties shall mutually agree (the "Closing"), provided that in no
                                                            --------
event shall Closing Date be more than three (3) business days after satisfaction
of the condition set forth in Section 4.8 hereof.

          (c)  At the Closing, the Company will deliver to JJDC a certificate or
certificates, registered in JJDC's name, representing the Shares, and JJDC shall
deliver an amount equal to the Purchase Price to the Company by certified check
payable to the Company or wire transfer of immediately available funds to an
account specified by the Company.

          2. Representations and Warranties of the Company.  The Company hereby 
             ---------------------------------------------                      
represents and warrants to JJDC that:

          2.1  Organization and Corporate Power.  The Company is a corporation 
               --------------------------------                                
duly organized, validly existing and in good standing as a corporation under the
laws of the State of Delaware and is qualified to do business as a foreign
corporation in each jurisdiction where the failure to qualify would have a
Material Adverse Effect on the Company. For purposes of this Agreement, a
"Material Adverse Effect" or "Material Adverse Change" shall mean, with respect
to the Company, any adverse effect or change in the condition (financial or
other), business, results of operations, prospects, assets, liabilities or
operations of the Company or on the ability of the Company to consummate any of
the transactions contemplated hereby, or any event or condition that would, with
or without the passage of time, constitute a "Material Adverse Effect" or
"Material Adverse Change." The Company has full corporate power and authority to
own its property, to carry on its business as presently conducted and to carry
out the transactions contemplated hereby. The copies of the Certificate of
Incorporation and Bylaws of the Company, as amended to date, which have been
furnished to JJDC by the Company, are correct and complete copies of the
originals.

          2.2  Authorization.  The Company has full corporate power and 
               -------------                                            
authority to execute, deliver and perform this Agreement, the License Agreement
and each other agreement entered into by the Company in connection with this
Agreement. Each such agreement has been duly executed and delivered by the
Company and is the legal, valid and, assuming due execution by the other parties
hereto and thereto, binding obligation of the Company, enforceable against the
Company in accordance with its terms, subject to applicable bankruptcy,
insolvency, moratorium, reorganization or similar laws affecting creditors'
rights generally, and to general equitable principles. The execution, delivery
and performance of this Agreement, including the sale, issuance and delivery of
the Shares, and the License Agreement, and each other agreement entered into by
the Company in connection with this Agreement, has been duly authorized by all
necessary corporate action of the Company.

          2.3  Capitalization. When issued in accordance with the terms of this
               --------------                                                  
Agreement, the Shares will be duly authorized, validly issued and outstanding,
fully paid and nonassessable, free of any liens, encumbrances, preemptive rights
or rights of first refusal and will be issued in compliance with all applicable
federal and state securities laws. The entire authorized capital stock of the
Company consists of 50,000,000 shares $0.0l par value, of Common Stock, of which
approximately 13,500,000 shares are issued and outstanding, and 10,000,000
shares, $0.0l par value, of preferred stock of which 6,903 shares are issued and
outstanding.  The outstanding shares of Common Stock have been duly authorized
and validly issued and are fully paid and nonassessable, and were issued in
compliance with all applicable federal and state securities laws.  No shares of
Common Stock or Preferred Stock are held in the Company's treasury. There are no
outstanding securities, warrants, rights of first refusal, options or other
rights to purchase or acquire, or exchangeable for or convertible into, any
shares of Common Stock or Preferred 

                                       2
<PAGE>
 
Stock other than those set forth on Exhibit A hereto or as set forth in the
Public Reports (as defined hereinafter). The Company has reserved 2,000,000
shares of Common Stock under its stock option plans. There are no preemptive
rights with respect to the issuance or sale by the Company of any of its
securities. Upon consummation of the transactions contemplated hereby, JJDC will
acquire good and valid title to the Shares, free and clear of any encumbrances,
liens, claims, charges or assessments of any nature whatever.

          2.4  Subsidiaries.  The Company has no subsidiaries and no 
               ------------                                          
investments, directly or indirectly, in any other corporation or business
organization other than as set forth on Exhibit B hereto. The Company is not a
participant in any joint venture or partnership.

          2.5  Financial Statements. The audited consolidated balance sheets and
               --------------------                                             
statements of operations and cash flow for the Company included in the Public
Reports (collectively, the "Financial Statements") are materially complete and
correct in all matters and respects, are in accordance with the books and
records of the Company, have been prepared in accordance with generally accepted
accounting principles, consistently applied, and fairly present the financial
position of the Company as of each such date and the results of operations for
each such period then ended.

          2.6  Absence of Undisclosed Liabilities.  Except as and to the extent
               ----------------------------------                              
reflected or stated in the Financial Statements, the Company has no debts,
liabilities or obligations of any nature, whether accrued or absolute, assigned
or otherwise, or whether due or to become due in excess of $100,000.

          2.7  Absence of Certain Developments.  Since the date of the Company's
               -------------------------------

Q"), (a) there has not been any Material Adverse Change with respect to the
Company, and (b) the Company has not entered into any transaction except in the
ordinary course of business and consistent with past practice, or entered into
any agreement (contingent or otherwise) to do so.

          2.8  Title to Properties.  Except as disclosed in the Financial 
               -------------------                                        
Statements, the Company has good and marketable title to, or has a valid
leasehold interest in, or a valid license for, all of the properties and assets
reflected in the Financial Statements, free and clear of all mortgages, security
interests, liens, restrictions or encumbrances other than (i) the lien of
current taxes not yet due and payable and (ii) possible minor liens and
encumbrances which do not in any case, individually or in the aggregate,
materially detract from the value of the property subject thereto or materially
impair the operations of the Company, would not result in the occurrence of a
Material Adverse Change, and which have not arisen otherwise than in the
ordinary course of business.

          2.9  Tax Matters.
               ----------- 

                                       3
<PAGE>
 
          (a)   All taxes, including, without limitation, income, excise,
property, sales, transfer, use, franchise, payroll, employees' income
withholding and social security taxes imposed or assessed by the United States
or by any foreign country or by any state, municipality, subdivision or
instrumentality of the United States or of any foreign country, or by any other
taxing authority, which are due or payable by the Company, and all interest,
penalties and additions thereon, whether disputed or not, have been paid in
full; all tax returns or other documents required to be filed in connection
therewith have been accurately prepared and duly and timely filed; and the
Company is not the beneficiary of any extension of time within which to file any
such returns. The Company has not been delinquent in the payment of any foreign
or domestic tax, assessment or governmental charge or deposit and has no tax
deficiency or claim outstanding, assessed or, to the best of its knowledge,
proposed against it, and there is no basis for any such deficiency or claim. No
issues have been raised (or are currently pending) by the Internal Revenue
Service or any other taxing authority in connection with any of the returns and
reports referred to above, and no waivers of statutes of limitations have been
given or requested with respect to the Company in connection therewith. The
provisions for taxes in the Financial Statements are sufficient in all material
respects for the payment of all accrued and unpaid federal, state, county and
local taxes of the Company for the periods then ended.

          (b)   The Company is not a party to or bound by any tax indemnity, tax
sharing or tax allocation agreement.

          (c)   The Company is not presently a member nor has it ever been a
member of an affiliated group of corporations within the meaning of Section 1504
of the Internal Revenue Code of which it is or was not the parent company.

          2.10  No Defaults.  The Company is not in violation of any term or 
                -----------                                                  
provision of (a) its Certificate of Incorporation or Bylaws, as amended to date,
or in any material respect any note, indenture, mortgage, lease, agreement,
contract, purchase order or other material instrument, document or agreement to
which the Company is a party or by which it or any of its properties or assets
is bound or affected or (b) any order, writ, injunction or decree of any court
or any federal, state, municipal or other governmental department, authority,
commission, board, bureau, agency or instrumentality, domestic or foreign. There
exists no condition, event or act which constitutes, or which after notice,
lapse of time or both, would constitute a material default under any of the
foregoing.

          2.11  Intellectual Property.  The Company owns or possesses the 
                ---------------------  
right to use or license all material, patents, trademarks, service marks, 
                        ===                                               
trade names, copyrights, trade secrets, proprietary rights, licenses and 
inventions necessary for the proper conduct of its business as now conducted,
and as proposed to be conducted, without conflict with or infringement of the
rights of others other than those listed in its Public Reports. There are no
outstanding options, licenses, or agreements of any kind relating to the
foregoing, nor is the Company bound by or a party to any options, licenses or
agreements of any kind with respect to the patents, trademarks, service marks,
trade names, copyrights, trade secrets, licenses, information, proprietary
rights and

                                       4
<PAGE>
 
processes of any other person or entity, which would be material to the
Company's business as conducted or, to the best of the Company's knowledge, as
proposed to be conducted. The Company has not received any communications
alleging, nor is the Company aware, to the best of its knowledge, of any basis
for such allegation, that the Company has violated, or by conducting its
business as proposed, would violate any of the patents, trademarks, service
marks, tradenames, copyrights or trade secrets or other proprietary rights of
any other person or entity. No other firm, corporation, association or person
(i) has notified the Company that it is claiming any ownership of or right to
use any of the Company's patents, trademarks, service marks, tradenames,
copyrights or trade secrets or other proprietary rights, or (ii) to the best of
the Company's knowledge, is infringing upon any such patents, trademarks,
service marks, tradenames, copyrights or trade secrets or other proprietary
rights. The Company is not aware, to the best of its knowledge, that any of its
employees is obligated under any contract (including, licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
the use of such employee's best efforts to promote the interests of the Company
or that would conflict with the Company's business as proposed to be conducted.
Neither the execution nor delivery of this Agreement, nor the carrying on of the
Company's business by the employees of the Company, nor the conduct of the
Company's business as proposed, will, to the best of the Company's knowledge,
conflict with or result in a breach of the terms, conditions or provisions of,
or constitute a default under, any contract, covenant or instrument under which
any of such employees now obligated. Each employee of and consultant to the
Company with access to confidential or proprietary information has executed a
proprietary information agreement obligating such employee or consultant to hold
all such information in confidence. The Company does not believe, to the best of
its knowledge, that it is or will be necessary to utilize any inventions of any
of its employees (or people it currently intends to hire) made prior to their
employment by the Company for which licenses have not already been obtained.

          2.12  Effect of Transactions.  The execution, delivery and 
                ----------------------                               
performance of this Agreement and the transactions contemplated hereby, and
compliance with the provisions hereof by the Company, do not and will not, with
or without the passage of time or the giving of notice or both, (a) violate any
provision of law, statute, rule or regulation or any ruling, writ, injunction,
order, judgment or decree of any court, administrative agency or other
governmental body or (b) conflict with or result in any breach of any of the
terms, conditions or provisions of, or constitute a default (or give rise to any
right of termination, cancellation or acceleration) under, or result in the
creation of any lien, security interest, charge or encumbrance upon any of the
properties or assets of the Company, under the Certificate of Incorporation or
Bylaws, as amended to date, of the Company or any material note, indenture,
mortgage, lease, agreement, contract, purchase order or other instrument,
document or agreement to which the Company is a party or by which it or any of
its properties or assets is bound or affected, except in any case where such
occurrence would not have a Material Adverse Effect on the Company.

          2.13  No Governmental Consent or Approval Required.  Based in part on 
                --------------------------------------------                    
the representations made by JJDC in Section 3 of this Agreement, no
authorization, consent,

                                       5
<PAGE>
 
approval or other order of, declaration to, or registration, qualification,
designation or filing with, any federal, state or local governmental agency or
body is required for or in connection with the valid and lawful authorization,
execution and delivery by the Company of this Agreement, the License Agreement
or any other agreement entered into by the Company in connection with this
Agreement, and the consummation of the transactions contemplated hereby or
thereby, or for or in connection with the valid and lawful authorization,
issuance, sale and delivery of the Shares, other than (i) applicable obligations
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the rules and
regulations thereunder (the "HSR Act"), (ii) the qualification (or taking of
such action as may be necessary to secure an exemption from qualification if
available) of the offer and sale of the Shares under the applicable state and
federal securities laws, which filings and qualifications, if required, will be
accomplished in a timely manner so as to comply with such qualification or
exemption from qualification requirements, and (iii) the approval of the Shares
for listing on Nasdaq.

          2.14  Litigation.  Except as disclosed in the 10-Q, there is no (a) 
                ----------                                                    
claim, arbitration, action, suit, proceeding or investigation at law or in
equity or by or before any governmental instrumentality or other agency pending,
or to the best knowledge of the Company, threatened against the Company, or (b)
judgment, decree, injunction or order of any court, governmental department,
commission, agency, instrumentality or arbitrator against the Company, nor, to
the best knowledge of the Company, does there exist any basis therefor.

          2.15  Securities Laws.  Assuming that JJDC's representations and

<PAGE>
 
               a.  Authorization.  JJDC has full power and authority to execute,
                   -------------                                        
deliver and perform this Agreement and to purchase the Shares. Assuming due
execution by the Company hereto, this Agreement constitutes the valid and
legally binding obligation of JJDC, enforceable against JJDC in accordance with
its terms, subject to applicable bankruptcy, insolvency, moratorium,
reorganization or similar laws affecting creditors' rights generally, and to
general equitable principles.

               b.  Purchase Entirely for Own Account.  The Shares to be received
                   ---------------------------------                    
by JJDC will be acquired for investment for JJDC's own account, not as a nominee
or agent and not with a view to the distribution of any part thereof. JJDC has
no present intention of selling, granting any participation in, or otherwise
distributing the same. JJDC does not have any contract, undertaking, agreement
or arrangement with any person to sell, transfer, or grant participation to such
person or to any third person, with respect to any of the Shares.

               c.  Restrictions on Disposition.  JJDC covenants that in no 
                   ---------------------------                             
event will it dispose of any of the Shares (other than pursuant to Rule 144
promulgated under the 1933 Act ("Rule 144") or pursuant to a registration
statement filed with the Securities and Exchange Commission (the "SEC") pursuant
to the 1933 Act) unless and until (i) JJDC shall have notified the Company of
the proposed disposition and shall have furnished the Company with a statement
of the circumstances surrounding the proposed disposition, and (ii) if requested
by the Company, JJDC shall have furnished the Company with an opinion of JJDC's
counsel, reasonably satisfactory in form and substance to the Company and the
Company's counsel, to the effect that (a) such disposition will not require
registration under the 1933 Act or (b) appropriate action necessary for
compliance with the 1933 Act and any applicable state, local or foreign law has
been taken. The restrictions on transfer imposed by this Section 3.1(c) shall
cease and terminate as to the Shares when: (i) such Shares shall have been
effectively registered under the 1933 Act and sold by the holder thereof in
accordance with such registration, or (ii) an opinion of the kind described in
the preceding sentence states that all future transfers of such Shares by the
holder thereof would be exempt from registration under the 1933 Act. Each
certificate evidencing the Shares shall bear an appropriate restrictive legend
as set forth in Section 3.3 below, except that such certificate shall not be
required to bear such legend after a transfer thereof if the transfer was made
in compliance with Rule 144 or pursuant to a registration statement or, if the
opinion of counsel referred to above is issued and provides that such legend is
not required in order to establish compliance with any provisions of the 1933
Act.

               d.  Receipt of Information.  JJDC has been furnished access to 
                   ----------------------

documents as JJDC has requested and has been afforded an opportunity to ask
questions of and receive answers from representatives of the Company concerning
the terms and conditions of this Agreement and the purchase of the Shares.

contemplated by this Agreement based on any arrangement or agreement made by or
on behalf of JJDC, and JJDC agrees to indemnify and hold the Company harmless

necessary for a transfer by JJDC of the Shares to a subsidiary, shareholder or
Affiliate (as such term is defined in the License Agreement) of JJDC, if the

extent as if such transferee were JJDC hereunder.

                   ----------------                                        
Section 3.1(c) hereof shall terminate as herein provided, the holder of the
Shares as to which such restrictions have terminated shall be entitled to
receive from the Company, without expense, one or more new certificates not
bearing restrictive legends and not containing any reference to the restrictions
imposed by this Agreement.

     BOSTON, February 24, 1998  Ergo Science Corporation (Nasdaq:ERGO) today
reported that it has entered into a worldwide collaboration with The R.W.
Johnson Pharmaceutical Research Institute (PRI) and Ortho-McNeil Pharmaceutical,
Inc., both Johnson & Johnson (NYSE:JNJ) units, to develop and commercialize
ERGOSET(TM)/1/ (bromocriptine mesylate) tablets, Ergo Science's lead product,
and other potential products for the treatment of Type 2 diabetes and obesity,
based on Ergo Science's novel Neuroendocrine Resetting Therapy (NRT). The New
Drug Application (NDA) for use of ERGOSET(TM) tablets for the treatment of Type
2 diabetes was accepted for filing by the U.S. Food and Drug Administration
(FDA) in October 1997.

     In the United States, Ergo Science will share equally in the costs of
developing and commercializing its lead product and other collaboration products
and will share equally in any resulting profits.  Outside the United States,
Ergo Science will receive a royalty on net trade sales of collaboration
products.  Under the agreement, initial payments to Ergo Science include a $10
million license fee and a $10 million equity investment in common stock by
Johnson & Johnson Development Corporation.  The license agreement is subject to
clearance under the Hart-Scott-Rodino Antitrust Improvement Act of 1976.

formulation of bromocriptine mesylate, presently known as ERGOSET(TM) tablets
for Type 2 diabetes.

   ADD 1 -- ERGO SCIENCE AND JOHNSON & JOHNSON FORM WORLDWIDE COLLABORATION
     AGREEMENT ON ERGO SCIENCE'S PRODUCTS FOR TYPE 2 DIABETES AND OBESITY

     In addition to sharing equally in costs and any profits, Ergo Science will
receive $20 million in milestone payments upon receipt of FDA marketing
clearance for use of its lead product for the treatment of Type 2 diabetes.
Significant additional milestones will be paid to Ergo Science upon achievement
of specified regulatory objectives for the use of its lead product for Type 2
diabetes within and outside the United States, upon achievement of specified
development and regulatory objectives related to a collaboration product for the
treatment of obesity, upon achievement of specified commercial objectives for a
product which includes an obesity indication, and the election of Johnson &
Johnson to participate in development of a collaboration product for treating a
non-metabolic disease.

     All development work for collaboration products will be coordinated jointly
by Ergo Science and PRI.  Ergo Science will remain responsible for U.S.
marketing clearance for its lead product for Type 2 diabetes.  PRI will pursue
development and registration activities outside the U.S. for all collaboration
products.  Subject to regulatory clearance, Ortho-McNeil will market all
collaboration products in the U.S.; Janssen-Cilag and other Johnson & Johnson
companies will market these products outside the U.S.

     "The joint collaboration with Johnson & Johnson brings together
complementary strengths of our respective organizations.  We are proud to build
a partnership with a company like Johnson & Johnson in these two important
fields of medical research," said Ronald H. Abrahams, Ph.D., Chairman and Chief
Executive Officer of Ergo Science.

     Ergo Science's fast-release, once-a-day, oral formulation of bromocriptine
is a potent dopamine-receptor agonist, which operates through a mechanism of
action that is different from other anti-diabetic drugs. The development of this
product is based on Ergo Science's NRT technology, a novel approach to treating
glucose and lipid metabolism disorders.

     NRT is based on over 30 years of research by Ergo Science's founding
scientists into the role of neurotransmitters in regulating metabolism.  This
research indicates that distinct, daily activity patterns of certain
neurotransmitters are required to maintain normal glucose and lipid metabolism.
Disorders in glucose and lipid metabolism can develop and progress as a result
of changes in these daily patterns of neurotransmitter activity.  With NRT, a
neurotransmitter-modulating agent is administered at a specific time of day to
re-establish normal patterns of neurotransmitter activity and thereby improve
glucose and lipid metabolism.

   ADD 2 -- ERGO SCIENCE AND JOHNSON & JOHNSON FORM WORLDWIDE COLLABORATION
     AGREEMENT ON ERGO SCIENCE'S PRODUCTS FOR TYPE 2 DIABETES AND OBESITY
                                        
     Ergo Science's NDA is supported by the Company's three Phase III studies
that evaluated the safety and efficacy of Ergo Science's lead product for the
treatment of Type 2 diabetes.  Data from these studies indicated that this
product, compared to placebo, significantly decreased glycated hemoglobin A1C
(HbA1c) (the primary measure for assessing long-term glucose control in
diabetes).  In addition, fasting and post-prandial glucose, triglyceride and
free fatty acid levels improved.  Elevated levels of triglycerides and free
fatty acids are risk factors for cardiovascular disease, the leading cause of
death in Type 2 diabetics.

     In July 1997, Ergo Science initiated a 400 person, dose selection Phase II
clinical trial to evaluate the use of Ergo Science's lead product in reducing
weight in obese subjects.  This obesity trial will become part of the joint
collaboration with Johnson & Johnson, and Ergo Science will retain the
responsibility for conducting this study.

     Dr. Abrahams stated, "We are excited about collaborating with Johnson &
Johnson in the continued clinical development of our technology for the
treatment of obesity."
