                      CONSIDERATION FOR TRANSFER OF ASSETS

         2.1 PURCHASE PRICE. (a) Subject to the terms and conditions of this
Agreement, in consideration for the sale and transfer of the Assets, Horizon
shall pay to Warner-Lambert (i) a non-refundable payment of Three Million Five
Hundred Thousand Dollars ($3,500,000) payable to Warner-Lambert on the Closing
Date, (ii) One Million Five Hundred Thousand Dollars ($1,500,000) payable to
Warner-Lambert upon the approval by the United States Food and Drug
Administration (the "FDA") of a new drug application ("NDA") for Cognex CR in
the United States which includes an approved package insert with the attributes
provided in Exhibit 2.1, as adjusted by the Price Adjustment described in
Section 2.1(b) below, if any; provided, however, that Horizon shall not be
required to seek approval of the NDA for Cognex CR from the FDA, and (iii) an
amount equal to the value of the Inventory transferred to Horizon pursuant to
the terms of this Agreement based on the Closing Inventory Value (as defined
below) payable to Warner-Lambert within thirty (30) days after the Closing Date.
The amounts set forth in Section 2.1 (a)(i), (ii) and (iii) are hereinafter
referred to collectively as the "Purchase Price". As used herein, "Business Day"
means a day during which banks are generally open for business in New York and
"Closing Inventory Value" means the value of the Inventory (including samples)
as of the Closing Date based on Warner-Lambert's calculation of the standard
cost of the Product.

          (b) The amount payable pursuant to Section 2.1(a)(ii) above will be
reduced by an amount which is equal to the product of (i) total third-party
out-of-pocket expenses, reasonably incurred by Horizon relating to (A) the
performance by or on behalf of Horizon of additional studies in connection with
the approval of the NDA for Cognex CR to the extent required by the FDA
(including, but not limited to, manufacturing costs in connection with the
manufacture of trial batches of the Product and costs of literature searches and
analysis required for such studies) plus (B) returns incurred during the twelve
(12) month period following the Closing Date for Product sold prior to the
Closing Date by Warner-Lambert in an aggregate amount greater than $1.8 million
but less than $2.8 million ("Total Expense") and (ii) the applicable Factor (as
hereinafter defined) (the "Price Adjustment"). "Factor" shall be determined as
follows: if Total Expense is (i) less than or equal to $200,000 then the factor
will be 1.35, and (ii) greater than $200,000 and less than or equal to $500,000
then the factor will be 1.50. If Total Expenses is greater than $500,000 then
Horizon will not have any obligation to pay the amount set forth in Section
2.1(a)(ii). Under no circumstances shall Warner-Lambert incur any obligation to
pay Horizon as a result of the calculation of the Price Adjustment.
Warner-Lambert makes no representation or warranty that the NDA for Cognex CR
will be accepted for filing or approved by the FDA.

         (c) Within thirty (30) days of the approval of the NDA for Cognex CR,
Horizon shall prepare and deliver to Warner-Lambert a written report showing the
components of Total Expenses (including returns) and the amount payable pursuant
to Section 2.1(a)(ii), if any (the "Report"). Concurrently with the submission
of such written report, Horizon shall pay Warner-Lambert the amount shown to be
due thereon; provided, however, if the NDA for Cognex CR is approved by the FDA
during the twelve month period following the Closing Date, Horizon shall prepare
the Report within thirty (30) days following the end of such twelve (12) month
period.

         (d) Horizon shall keep accurate records in sufficient detail to
determine the amount payable under Section 2.1(a)(ii). Warner-Lambert may
designate an independent public accountant mutually acceptable to Warner-Lambert
and Horizon to review such records to verify


                                       6
<PAGE>   8


the accuracy of information provided to Warner-Lambert. Warner-Lambert shall
pay the cost of any review of records conducted at the request of
Warner-Lambert under this Section; provided, however, that if the independent
public accountant conducting the review concludes that the amount payable under
Section 2.1(a)(ii) was understated by 5% or more, Horizon shall pay the cost of
such review.

         (e) All payments under this Section shall be made by wire transfer or
other immediately available funds to an account indicated by Warner-Lambert.

         2.2 ALLOCATION. The parties agree to allocate the Purchase Price among
the Assets in accordance with Exhibit 2.2.

         2.3 CLOSING. The Closing shall take place at 11:00 a.m. EDT at 201
Tabor Road, Morris Plains, New Jersey on the Closing Date or at such time and
place as the parties hereto may otherwise mutually agree.

                                INDEMNIFICATION


         4.1 INDEMNIFICATION BY WARNER-LAMBERT. Warner-Lambert shall indemnify,
defend and hold harmless Horizon against any loss, expense, liability or other
damages, including reasonable costs of investigation, interest, penalties and
attorneys' fees (collectively, "Losses") incurred by Horizon, its Affiliates or
any of their respective officers, directors, agents or employees (collectively,
the "Horizon Group") to the extent relating to or resulting from (a) any
inaccuracy of a representation or breach of a warranty made by Warner-Lambert
in this Agreement or (b) the Retained Liabilities; provided, however, that
Warner-Lambert will have no obligations under this Section for Losses to the
extent that they are caused by (i) any inaccuracy of a representation or breach
of a warranty made by Horizon in this Agreement or (ii) the gross negligence or
willful misconduct of any member of the Horizon Group. Horizon hereby agrees
that Warner-Lambert's liability under this Agreement from whatever cause,
whether pursuant to this Section or any other cause arising under this
Agreement, is limited to the amounts paid by Horizon to Warner-Lambert pursuant
to Section 2.1 as of the date of determination of such liability, provided,
however, that the limitation on liability contained in this sentence shall not
apply to a failure of the Inventory to meet the Specifications, where such
failure was due solely to the actions or omissions of Warner-Lambert.
Furthermore, the parties agree that in no event will Warner-Lambert be liable
to Horizon hereunder for special, consequential, indirect, punitive or similar
damages.

         4.2 INDEMNIFICATION BY HORIZON. Horizon shall indemnify, defend and
hold harmless Warner-Lambert against any Losses incurred by Warner-Lambert, its
Affiliates or any of their respective officers, directors, agents or employees
(collectively, the "Warner Group") relating to or resulting from (a) any
inaccuracy of a representation or breach of a warranty made by Horizon in this
Agreement; (b) any liabilities, obligations, commitments of, or claims against
any member of the Warner Group based on the manufacture, use or sale of the
Product in the Territory or use of the Trademarks or the Registrations in the
Territory, on and after the Closing Date; and (c) the Assumed Liabilities;
provided, however, that Horizon will have no obligations under this Section for
Losses to the extent that they are caused by (a) any inaccuracy of a
representation or breach of a warranty made by Warner-Lambert in this Agreement
or (b) the gross negligence or willful misconduct of any member of the Warner
Group. Furthermore, the


                                      10
<PAGE>   12


parties agree that in no event will Horizon be liable to Warner-Lambert
hereunder for special, consequential, indirect, punitive or similar damages.

         4.3 INDEMNIFICATION PROCEDURES. In any case under this Agreement where
one party has indemnified the other against any claim or legal action,
indemnification will be conditioned on compliance with the procedure outlined
below. Provided that prompt notice is given of any claim or suit for which
indemnification might be claimed, the indemnifying party promptly will defend,
contest or otherwise protect against any such claim or suit (including by way
of settlement and release) at its own cost and expense. The indemnified party
may, but will not be obligated to, participate at its own expense in a defense
thereof by counsel of its own choosing, but the indemnifying party will be
entitled to control the defense unless the indemnified party has relieved the
indemnifying party from liability with respect to the particular matter. If the
indemnifying party fails timely to defend, contest or otherwise protect against
any such claim or suit, the indemnified party may, but will not be obligated
to, defend, contest or otherwise protect against the same, and make any
compromise or settlement thereof and recover the entire costs thereof from the
indemnifying party, including reasonable attorneys fees, disbursements and all
amounts paid as a result of such claim or suit or the compromise or settlement
thereof; provided, however, that if the indemnifying party undertakes the
timely defense of such matter, the indemnified party will not be entitled to
recover from the indemnifying party its costs incurred in the defense thereof.
The indemnified party will cooperate and provide such assistance as the
indemnifying party may reasonably request in connection with the defense of the
matter subject to indemnification.

                             ADDITIONAL AGREEMENTS

         5.1 MONTHLY REPORTS; RETURNS. (a) During the twelve month period
following the Closing Date, Horizon shall prepare and deliver to Warner-Lambert
a written monthly report showing all returns received by Horizon of Product sold
prior to the Closing Date by Warner-Lambert (the "Returns"). Within thirty (30)
days of the receipt of such monthly report, Warner-Lambert shall reimburse
Horizon for payments made by Horizon with respect to such Returns up to $1.8
million in the aggregate.

         (b) Horizon shall keep accurate records in sufficient detail to
determine the amount of the reimbursement payable by Warner-Lambert under this
Section 5.1. Warner-Lambert may designate an independent public accountant
mutually acceptable to Warner-Lambert and Horizon to review such records to
verify the accuracy of information provided to Warner-Lambert. Warner-Lambert
shall pay the cost of any review of records conducted at the request of
Warner-Lambert under this Section; provided, however, that if the independent
public accountant conducting the review concludes that the amount payable under
this Section 5.1 were overstated by 5% or more, Horizon shall pay the cost of
such review.

         5.2 USE OF WARNER-LAMBERT NAME. (a) Horizon shall not use the name of
Warner-Lambert, Parke-Davis or any of Warner-Lambert's Affiliates (collectively,
the "Warner-Lambert Name") in any manner whatsoever in connection with the
manufacture, use, sale, promotion, advertising or distribution of the Product
after the Closing Date, provided, however, Horizon may use the inventory and
Promotional Materials purchased from Warner-Lambert by Horizon


                                      11
<PAGE>   13


hereunder bearing the Warner-Lambert Name (including inventory purchased under
the Supply Agreement) until such inventory expires or is depleted, whichever
occurs first ("Final Inventory Sell Off Date"). Except as otherwise set forth
in this Section 5.2 or in Section 5.3 hereof, Horizon shall have no right to
use the Warner-Lambert Name without the prior written consent of
Warner-Lambert.

         (b) Horizon hereby agrees that any Inventory purchased from
Warner-Lambert hereunder and bearing the Warner-Lambert Name will be held,
maintained and distributed in accordance with applicable pharmaceutical current
good manufacturing practices, the Registrations, and all applicable laws.
Warner-Lambert shall have no responsibility for costs and expenses associated
with any recall of the Inventory on or after the Closing Date attributable to a
determination by a Governmental or Regulatory Authority that the use of the
Warner-Lambert Name on such Inventory would constitute misbranding within the
meaning of the Federal Food, Drug, and Cosmetic Act or similar laws in the
Territory.

         5.3 USE OF PROMOTIONAL MATERIALS. Horizon hereby agrees that any
Promotional Materials purchased from Warner-Lambert hereunder and bearing the
Warner-Lambert Name (i) will not be used after the Final Inventory Sell Off
Date; and (ii) will be held, maintained and distributed in accordance with the
Registrations and all applicable laws. From the Closing Date until the Final
Inventory Sell Off Date, Horizon shall have the right, subject to
Warner-Lambert's prior written consent, to apply the Warner-Lambert Name on any
new promotional materials (including, but not limited to, journal ads,
convention materials, sales aids, and medical education materials) for the
Product. Horizon shall submit such promotional materials in final form, together
will all data and documentation required to support any claims made therein, to
Warner-Lambert's regulatory group which shall determine, within ten (10)
Business Days after receipt, whether to grant written consent to use such
promotional materials. Horizon shall have no other right to use the
Warner-Lambert Name other than as set forth herein and in Section 5.2 above.
Horizon agrees that after the Final Inventory Sell Off Date all promotional
materials and Promotional Materials containing the Warner-Lambert Name shall be
destroyed at Horizon's sole cost and expense. Use of the Warner-Lambert Name on
promotional materials and the use of the Promotional Materials by Horizon shall
be at Horizon's risk.

         5.4 PRODUCT REGULATORY OBLIGATIONS.

                  5.4.1. FDA Contacts. On and after the Closing Date, Horizon
shall be responsible for all contacts with the FDA and other regulatory
authorities with respect to the Product, and all other responsibilities under
the Registrations; provided that either party shall notify the other party
immediately, and in no event later than (A) forty-eight (48) hours after receipt
of any contact or communication from the FDA or any other Governmental or
Regulatory Authority in the Territory and (B) five (5) Business Days after
receipt of any contact or communication with any other third party, that in
either case, in any way requests or suggests the need for a recall or withdrawal
of a lot of Product manufactured by or on behalf of Warner-Lambert or otherwise
calls into question the quality or safety of such a Product lot. Horizon shall
be responsible for investigating any such request or suggestion and for any
communications with any Governmental or Regulatory Authority relating thereto;
provided that Horizon shall comply with all reasonable requests by
Warner-Lambert.

                  5.4.2. Customer Complaints. Horizon shall be solely
responsible for responding to any Product complaint received on or after the
Closing Date. Each party shall notify the other


                                      12
<PAGE>   14


in the event that such a party receives a report of a Product complaint
relating to a Product lot manufactured by or on behalf of Warner-Lambert. The
complaint recipient shall use all reasonable efforts to provide such notice to
the other party within forty eight (48) hours if the complaint involves
allegations of suspected or actual product tampering, contamination or
mislabeling, and shall provide such notice to the other party within five (5)
Business Days in the case of all other complaints. Horizon shall be responsible
for investigating all such Product complaints and responding to the
complainant, provided each party shall comply with all reasonable requests from
the other in connection therewith.

                  5.4.3. Adverse Event Reporting. (a) On and after the Closing
Date until such date that each of the Registrations are transferred to Horizon
(the "Transfer Date"), each party shall have a continuing obligation to notify
the other party of any adverse drug experience reported to such party arising
from or in connection with the use of the Product. This notification shall occur
within seventy-two (72) hours for an unexpected fatal or life-threatening
serious adverse drug experience (as defined in 21 CFR 312.32) associated with
the Product and arising during clinical trials. For post-marketing adverse drug
experience reports, the parties agree as follows:

         (i)      Warner-Lambert shall report to Horizon all adverse drug
                  experiences within five (5) Business Days after the time such
                  report becomes known to any employee, agent or Affiliate of
                  Warner-Lambert. All other post-marketing adverse drug
                  experience reports for the Product shall be reported to
                  Horizon by Warner-Lambert on a rolling fifteen (15)-day
                  basis.

         (ii)     Horizon shall report to Warner-Lambert all serious adverse
                  drug experience reports for the Product within five (5)
                  Business Days after the time such report becomes known to any
                  employee, agent or Affiliate of Horizon and all other adverse
                  drug experience reports for the Product on a rolling fifteen
                  (15)-day basis.

All notifications pursuant to this paragraph shall be by fax or e-mail at such
numbers (or e-mail addresses) agreed upon by the parties' respective drug safety
organizations. Horizon shall have sole responsibility to investigate such
adverse experience reports and for reporting such reports to Governmental and
Regulatory Authorities. Except as otherwise stated above, the terms "adverse
drug experience" and "serious adverse drug experience" used in this paragraph
shall have the meanings set forth in 21 CFR 314.80.

                  (b) On and after the Transfer Date, Warner-Lambert shall have
a continuing obligation to notify Horizon of any postmarketing adverse drug
experience reported to Warner-Lambert arising from or in connection with the use
of a Product in post-marketed use. This notification shall occur within five (5)
days for all post-marketing adverse drug experience reports. This notification
shall be by fax. Horizon shall have sole responsibility to investigate such
adverse experience reports and for reporting such reports to applicable
Governmental or Regulatory Authorities. Following the Closing Date, Horizon
shall provide Warner-Lambert with reasonable access to the post-marketing and

ongoing legal and/or regulatory requirements of Warner-Lambert.

                  (c) The parties shall use reasonable efforts to enter into a
separate drug safety sharing agreement describing the procedures and other
logistics to implement the provisions in this Section 5.4 within ninety (90)
days after execution of this Agreement.

                  5.4.4 Assistance with Regulatory Obligations Transfer. For a
period of up to sixty (60) days following the Closing Date, Warner-Lambert
agrees to provide assistance and cooperation reasonably requested by Horizon in
connection with the transfer of the Registrations to Horizon in the United
States and all other countries except the European countries in the Territory.
During the term of the Transition Services Agreement and for a period of up to
sixty (60) days following the termination of the Transition Services Agreement,
Warner-Lambert agrees to provide assistance and cooperation reasonably requested

the European countries in the Territory.

                  5.4.5 Transfer of Registration. The parties shall use all
reasonable efforts to transfer the Registrations from Warner-Lambert and the
Selling Affiliates to Horizon or its designee six (6) months after the Closing
Date.

         5.5 PAYMENT OF TRANSACTION EXPENSES. All sales taxes, use taxes, value
added taxes, transfer taxes, filing fees (including trademark assignment fees)
and similar taxes, fees, charges and expenses (excluding any taxes arising from

notice from Horizon, Warner-Lambert agrees to provide Horizon and up to two (2)
employees of an independent accounting firm designated by Horizon with
reasonable access to financial records pertaining to the Product covering a
period ending not more than three (3) years prior to the date of such request.
Prior to granting any access to such records, the designated accounting firm
shall first agree not to disclose any confidential information contained in such
financial records. Horizon shall pay all costs and expenses in connection with
the review of such financial records.

         5.7 LIMITATION ON TRANSFER. Horizon hereby agrees that until such time
as Horizon has discharged all its payment obligations hereunder (other than the
payment obligation set forth in Section 2.1(a)(ii)), it shall not convey, sell,
assign, transfer, license or otherwise dispose of any of the Assets (other than
Inventory in the ordinary course of business) without the prior written consent
of Warner-Lambert, which consent shall not be unreasonably withheld, provided,
that Horizon shall have the right to assign its rights and obligations under
this Agreement to any third party successor to all or substantially all of its
entire business. Warner-Lambert will respond to such written request for
transfer of the Assets within forty-five (45) days after receipt of such written
request from Horizon.

         5.8 CONFIDENTIALITY. For a period of five (5) years from the Closing
Date, each party shall hold in confidence and use its best efforts to have all
of their respective Affiliates and representatives hold in confidence all
confidential information of the other party, and, except as

<PAGE>   16


contemplated by this Agreement, shall not disclose, publish, use or permit
others to use the same; provided, however, that the foregoing restriction shall
not apply to any portion of the foregoing which was or becomes available on a
non-confidential basis to the other party or when such disclosure is required
by a Governmental or Regulatory Authority or is otherwise required by law or is
necessary in order to establish rights under this Agreement or any other
agreements referred to herein. In the event the transaction contemplated hereby
is not consummated, upon the request of the other party, each party hereto
will, and will cause its Affiliates, any Person who has provided, or who is
providing, financing to such party and their respective Representatives to,
promptly (and in no event later than five (5) Business Days after such request)

information furnished by the other party in connection with this Agreement or
the transactions contemplated hereby and destroy or cause to be destroyed all
notes, memoranda, summaries, analyses, compilations and other writings related

and instruments of transfer that may be reasonably necessary for the purpose of
assigning and granting to Horizon all Assets to be conveyed pursuant to this
Agreement.

         5.11 THIRD PARTY CONSENTS. To the extent that any Managed Care Contract
is not assignable without the consent of another party, this Agreement shall not
constitute an assignment or an attempted assignment thereof if such assignment
or attempted assignment would constitute a breach thereof. Warner-Lambert and
Horizon shall use their commercially reasonable efforts to obtain the consent of
such other party to the assignment of any such Managed Care Contract to Horizon
in all cases in which such consent is or may be required for such assignment. If
any such consent shall not be obtained, Warner-Lambert shall cooperate with
Horizon in any reasonable arrangement designed to provide for Horizon the
benefits intended to be assigned to Horizon under the relevant Managed Care
Contract, including enforcement at the cost and for the account of Horizon of
any and all right of Warner-Lambert or any of its Affiliates against the other
party thereto arising out of the breach or cancellation thereof by such other
party or otherwise. If and to the extent that such arrangement cannot be made,
Horizon shall have no obligation pursuant to Section 1.3 or otherwise with
respect to any such Managed Care Contract. The provisions of this Section 5.11
shall not affect the right of Horizon not to consummate the transactions
contemplated by this Agreement if the condition to its obligations hereunder
contained in Section 3.7 has not been fulfilled.

following the Closing Date, Horizon will operate the Business only in the
ordinary course.

         5.14 DOCUMENT RETENTION. Each party agrees for a period which is the
longer of three (3) years after the Closing Date and the applicable period
required by law or any Governmental or Regulatory Authority not to destroy or
otherwise dispose of any Registrations or Information unless such party shall
first offer in writing to surrender such documentation to the other party and
such other party shall not agree in writing to take possession thereof during
the ten (10) day period after such offer is made.

         5.15 CERTAIN FTC UNDERTAKINGS. (a) Horizon shall, within ten (10) days
after the Closing Date, submit to the United States Federal Trade Commission
(the "Commission") a certification attesting to its good faith intention to

or have manufactured Cognex, together with a business plan setting forth the
forecasted dates for completion of necessary preparations and final FDA
approvals.

         (b) Horizon shall, submit to the Commission and Interim Trustee
periodic reports setting forth, in detail, the efforts of Horizon to market the
Product and to obtain FDA approvals to sell and manufacture or have manufactured
the Product. Horizon shall submit the first such report sixty (60) days after
the date of the Consent Order relating to the merger of Warner-Lambert and
Pfizer Inc., and every sixty days thereafter, until all necessary FDA approvals
are obtained by or on behalf of Horizon.

         (c) In the event that Horizon (i) ceases to sell the Product in the
United States for a period exceeding sixty (60) days, or (ii) abandons its
efforts to obtain all necessary FDA approvals to sell and manufacture or have
manufactured Cognex, Horizon shall notify the Commission and the Interim Trustee
within ten (10) days thereafter. Horizon shall provide the Commission and the
Interim Trustee with access to all records and facilities that relate to its
efforts to manufacture and sell the Product.

         (d) In the event that Horizon, other than for reasons that are outside
of its control, (i) voluntarily ceases for sixty (60) days or more the sale of,
or otherwise fails to pursue good efforts to sell the Product in the United
States prior to obtaining all necessary FDA approvals; (ii) fails to pursue sale
and manufacture (or third party manufacture) of the Product within one (1) year
from the date the Commission approves this Agreement, provided, however, that
the one (1) year period may be extended by the Commission in three (3) month
increments for a period not to exceed one (1) year if it appears that such FDA
approvals are likely to obtain with such extended period, the Commission may
order that the Product revert to Warner-Lambert and the Product will be divested
by the divestiture trustee appointed by the Commission to a new purchaser.
Horizon shall be entitled to receive the proceeds from the sale of the Product
by the divestiture trustee, up to a maximum of $3.5 million, within thirty (30)
days after Warner-Lambert receives such proceeds. Warner-Lambert shall have no
further obligation or liability to Horizon in connection with the reversion of
Product to Warner-Lambert hereunder.

Commission to proceed with the transactions contemplated herein; (iii) by either
party in the event of a material breach by the other party of any of its

<PAGE>   23


         (c) If this Agreement is validly terminated pursuant to Section
8.3(a), this Agreement will forthwith become null and void, and there will be
no liability or obligation on the part of Warner-Lambert or Horizon (or any of
their representatives or Affiliates), except that the provisions with respect
to expenses in Section 5.5 and confidentiality in Section 5.8 will continue to
apply following any such termination.

         8.4 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations
and warranties made by Warner-Lambert in this Agreement shall survive from the
Closing Date for a period of two (2) years and terminate thereafter. All
indemnification provisions made by the parties hereto under this Agreement
shall survive indefinitely.

         8.5 SEVERABILITY. If any provision of this Agreement is held to be
invalid or unenforceable for any reason, the remaining provisions will continue
in full force without being impaired or invalidated in any way, and the parties
agree to replace any invalid provision with a valid provision which most
closely approximates the intent and economic effect of the invalid provision.

         8.6 HEADINGS. Headings used in this Agreement are for reference
purposes only and in no way define, limit, construe or describe the scope or
extent of such paragraph, or in any way affect this Agreement.

         8.7 NO WAIVER. No term or provisions hereof shall be deemed waived,
and no breach excused, unless such waiver or consent is in writing and signed
by the party claimed to have waived or consented. The waiver by any party of a
breach of any provision of this Agreement will not operate or be interpreted as
a waiver of any other or subsequent breach.

         8.8 RELATIONSHIP OF THE PARTIES. Nothing in this Agreement should be
construed to create a partnership, agency, joint venture or employer-employee
relationship. None of the parties has the authority to assume or create any
obligation, express or implied, on behalf of any other party.

accordance with the laws of the State of New York. Each party hereby consents
to the personal jurisdiction of the state and federal courts located in New
York.

         8.10 ENTIRE AGREEMENT; AMENDMENT. This Agreement, including all
Exhibits and Schedules hereto (which Exhibits and Schedules are hereby
incorporated into and made a part of this Agreement), and the additional
documents required to be delivered on the Closing Date, constitute the final,
complete and exclusive agreement among the parties with respect to the subject
matter hereof and supersede any previous proposals, negotiations, agreements,
arrangements or warranties, whether verbal or written, made among the parties
with respect to such subject matter. This Agreement may be amended or modified
only by mutual agreement in writing of the authorized representatives of the
parties.

         8.11 COUNTERPARTS. This Agreement may be executed in two or more

together constitute one and the same instrument. This Agreement shall become

make any reports, statements or releases to the public or generally to the
employees, customers, suppliers or other Persons with respect to this Agreement
or the transactions contemplated hereby without the consent of the other

unable to obtain the approval of its public report, statement or release from

party's disclosure obligations, then such party may make or issue the legally
required report, statement or release and promptly furnish the other parties
with a copy thereof. Warner-Lambert and Horizon will also obtain the other
parties' prior approval of any press release to be issued immediately following

2.        PRODUCTION ARRANGEMENT.

         2.1      Appointment. PURCHASER hereby appoints SUPPLIER and SUPPLIER
hereby agrees to be a supplier of the Product and the Active Ingredient to
PURCHASER pursuant to and for the term of this Agreement.

         2.2      Agreement to Supply and Purchase the Product. (a) Schedule A
hereto sets forth the total number of filled capsule shells of Product that
SUPPLIER will supply to PURCHASER during the year 2000. Schedule A shall
indicate the allocation of such filled capsule shells as between the U.S. and
the "rest of world."
<PAGE>   74

         (b)      On or prior to April 21, 2000, PURCHASER shall provide to
SUPPLIER a schedule (the "Production Schedule") indicating the manner in which
such filled capsule shells shall be packaged and labeled. The Production
Schedule shall include the information set forth on Schedule B to this
Agreement. SUPPLIER shall promptly confirm its ability to manufacture and
package the product in accordance with the Production Schedule. Thereafter,
SUPPLIER shall use its commercially reasonable efforts to supply to PURCHASER
the Product in such quantities and on such dates as set forth in the agreed-upon
Production Schedule, subject to SUPPLIER's ability to complete any required
packaging and labeling changes. In the event SUPPLIER is unable to supply the
Product to PURCHASER on a delivery date set forth on the Production Schedule,
for a reason other than SUPPLIER's inability to complete packaging and labeling
changes in time, SUPPLIER shall use its commercially reasonable efforts to
deliver such Product as soon as practicable thereafter, but in any event, no
later than thirty (30) days after the applicable delivery date.

         (c)      PURCHASER shall purchase from SUPPLIER Product in the
quantities and on the delivery dates set forth in the Production Schedule. In
the event PURCHASER fails at any time to purchase all Product manufactured and
made available for delivery by SUPPLIER as specified in this Section 2.2(b),
PURCHASER shall pay to SUPPLIER an amount equal to the total Production Fee
which would have otherwise been paid to SUPPLIER had PURCHASER purchased the
quantity specified on the Production Schedule on the applicable date.

         2.3      Active Ingredient and Raw Materials. (a) SUPPLIER will at all
times acquire, at its own cost and expense, the Active Ingredient and Raw
Materials, in such quantities as are necessary to enable SUPPLIER to manufacture
and supply the desired quantities of the Product during the term of this
Agreement. SUPPLIER will perform all quality control procedures with respect to
the Active Ingredient and Raw Materials in accordance with the Specifications.

         (b)      SUPPLIER will, or will cause its Affiliates to, use its
commercially reasonable efforts to provide PURCHASER with the Active Ingredient
in the quantity, on the delivery date and at the price set forth on Schedule C
hereto. In the event SUPPLIER or its Affiliate is unable to supply the Active
Ingredient to PURCHASER on the delivery date set forth on Schedule C, SUPPLIER
shall, or shall cause its Affiliate to, use its commercially reasonable efforts
to deliver such Active Ingredient as soon as practicable thereafter, but in any
event, no later than thirty (30) days after the original delivery date.

         (c)      PURCHASER shall purchase from SUPPLIER the Active Ingredient
in the quantities and on the delivery dates set forth in Schedule C. Subject to
Section 10.3 hereof, in the event PURCHASER fails at any time to purchase all of
the Active Ingredient manufactured and made available for delivery by SUPPLIER
as specified in this Section 2.3(c), PURCHASER shall pay to SUPPLIER an amount
equal to the total Production Fee which would otherwise have been paid to
SUPPLIER had PURCHASER purchased the quantity specified on Schedule C on the
applicable date.

         2.4      Changes to Production Schedule. Purchaser may request changes
to the Production Schedule relating to the allocation of Product among
countries, quantity and dosage strength and SUPPLIER shall use commercially
reasonable efforts to effectuate such changes; provided, however, that such
changes shall not in any way decrease the obligation of


<PAGE>   75

PURCHASER to purchase the aggregate equivalent amount of Product as set forth on
the Production Schedule as originally agreed upon by the parties.

         2.5      Controlling Provisions. In ordering and delivering, PURCHASER
and SUPPLIER may employ their standard forms, but nothing in those forms shall
be construed to modify or amend the terms of this Agreement and in case of
conflict herewith, this Agreement shall control.

3.       DELIVERY AND ACCEPTANCE.

         3.1      Delivery. The Products and Active Ingredient shall be
delivered to a carrier designated by PURCHASER at SUPPLIER's or its Affiliates
plants in Holland, Michigan, Vega Baja, Puerto Rico or Frieburg, Germany, as
PURCHASER shall direct. Title to and risk of loss for the Product or Active
Ingredient shall transfer to PURCHASER upon delivery to PURCHASER or its
designee at the designated location(s) set forth above.

         3.2      Acceptance of Shipments. After receipt of a shipment of
Products or Active Ingredient, PURCHASER shall within ten (10) Business Days
after delivery thereof, visually inspect the Product or Active Ingredient
shipment and communicate acceptance or rejection to SUPPLIER in writing. The
parties agree that PURCHASER's visual inspection consists of (i) comparing the
applicable order against the documentation accompanying the shipment to verify
that the delivery date, identity, quantity and exterior shipment labeling comply
with the order and (ii) visually inspecting the exterior of the shipment to
verify that the shipment appears to be in good condition.

         3.3      Failure to meet Specifications. In addition, after the date of
acceptance by PURCHASER pursuant to Section 3.2, PURCHASER shall be entitled to
return any shipment of Product or Active Ingredient, in whole or in part, to the
extent that such Product or Active Ingredient fails to meet Specifications (as
such Specifications existed on the date of delivery), where such failure is due
solely to the actions or omissions of SUPPLIER.

4.       PRODUCTION FEE AND PAYMENT.

         4.1      Production Fees. Subject to Sections 2.2(c) and 2.3(c),
PURCHASER will pay SUPPLIER the applicable Production Fees for Product
(including costs of Active Ingredient, Raw Materials, manufacturing, filling,
inspecting, quality control, stability testing and packaging) or Active
Ingredient delivered to PURCHASER hereunder.

         4.2      Invoices. SUPPLIER will issue an invoice to PURCHASER for the
full Production Fee with each shipment of the Product and Active Ingredient
delivered in accordance with Section 3.1. SUPPLIER will invoice PURCHASER in
U.S. dollars for all other amounts due hereunder on or after performance or
occurrence of the event that entitles SUPPLIER to be paid such amount by
PURCHASER. All invoices hereunder will be due and payable by PURCHASER in U.S.
dollars within thirty (30) days after receipt of the invoice by PURCHASER.

         4.3      Taxes. In addition to payment of the Production Fee, PURCHASER
will be responsible for the payment of any sales and use taxes on the Product or
Active Ingredient delivered by SUPPLIER to PURCHASER.

5.       QUALITY CONTROL.

         5.1      Manufacturing Process and Quality Assurance. The Product will
be manufactured by SUPPLIER in compliance with applicable laws and the
Specifications and in accordance with the manufacturing, quality assurance and
validation procedures currently employed by SUPPLIER in manufacturing the
Product or such other procedures as may be mutually agreed upon, or as may be
required under the applicable Marketing Authorizations.

         5.2      Modifications. Any request for modification of the
Specifications (including a change of the Raw Materials or Active Ingredient)
will be made by the requesting party to the other party in writing. SUPPLIER
will inform PURCHASER of the amount of any additional costs (including capital
expenditures) that any such modification would reasonably entail, if any, and,
if PURCHASER elects to adopt the modification, the Production Fee will be
increased by the amount of such additional costs, and the relevant documents and
related schedules will be revised accordingly. If SUPPLIER is technically unable
to comply with a modification proposed by PURCHASER or if PURCHASER is unwilling
to pay the additional costs associated with any modification, the requesting
party will have the option to withdraw the proposed modification or, if the
requesting party can demonstrate that it reasonably requires such modification
for business or regulatory reasons, to terminate this Agreement. Each party will
notify the other party as soon as reasonably possible of any proposed changes to
the Specifications, procedures or other areas that have an impact on the other
party's performance of this Agreement. In no event will SUPPLIER be required to
make (or not to make) a modification that it deems prohibited (or required) by
applicable regulations or regulatory authorities. Notwithstanding the foregoing,
SUPPLIER shall not have the right to terminate this Agreement pursuant to this
Section 5.2 if PURCHASER is unwilling to pay the additional costs associated
with any modification proposed by SUPPLIER, other than modifications that are
required for regulatory reasons.

         5.3      Testing. SUPPLIER will perform such quality assurance testing
as required under the applicable Specifications, and will provide evidence of
such testing to PURCHASER or its designee in a certificate of analysis for each
Product lot which confirms that the Product lot has been manufactured and
analyzed by SUPPLIER according with the applicable Specifications. SUPPLIER
shall provide a copy of the applicable certificate of analysis to PURCHASER with
each Product lot that is delivered to PURCHASER or by facsimile on the date of
delivery.

         5.4      Reimbursement for Non-Conforming Product. If the Product fails
to meet the Specifications, where such failure is due solely to the actions or
omissions of SUPPLIER, SUPPLIER will credit PURCHASER with the Reimbursement
Amount. The "Reimbursement Amount" will be deemed equal to the sum of any costs
reasonably expended by PURCHASER in order to identify the defect (i.e.,
testing), plus all Production Fees paid on account of the subject Product. The
Reimbursement Amount will be payable sixty (60) days after rejection of the
subject Product in accordance with this Section. At PURCHASER's option, (i)
SUPPLIER will be relieved of any obligation to deliver any Product with respect
to the non-conforming batch, or (ii) SUPPLIER will replace the non-conforming
batch with substitute Product that conforms with the Specifications and any
other requirements of this Agreement, within sixty (60) calendar days from the
date PURCHASER notifies SUPPLIER of its election of option (ii) of this Section
5.4, in which case PURCHASER will pay to SUPPLIER amounts in accordance with
Article 4 based on the substitute Product. SUPPLIER will dispose of the
non-conforming Product at its own expense This Section 5.4 sets forth
PURCHASER's sole remedy for non-conforming



<PAGE>   77

Product that is identified before sale thereof by PURCHASER to PURCHASER's
customer, and under no circumstances will SUPPLIER be liable to PURCHASER for
any damages, including, without limitation, direct, special, incidental or
consequential damages (including, without limitation, loss of business, profits,
or goodwill), arising therefrom (whether in contract, tort, negligence or
otherwise) or in connection with its performance under this Agreement.

         5.5      Access for Quality Control. Subject to SUPPLIER's reasonable
ability to assure the confidentiality of its other projects, SUPPLIER will
permit PURCHASER's representatives and representatives of applicable
Governmental or Regulatory Authorities to enter SUPPLIER's plants located in
Holland, Michigan, Vega Baja, Puerto Rico or Freiburg, Germany upon reasonable
advance written notice and at reasonable intervals during regular business hours
solely for the purpose of making quality control inspections of the facilities
used in production of the Product or Active Ingredient for PURCHASER, including
manufacturing, receiving, sampling, analyzing, storing, handling, packaging,
shipping and disposing of the Active Ingredient and the Product. In addition,
the parties agree that a member of SUPPLIER's pharmaceutical quality assurance
team shall be present at all such inspections.

6.       CONFIDENTIAL INFORMATION.

         6.1      Confidentiality. PURCHASER and SUPPLIER will at all times
maintain as confidential any information, technology, formulation, process,
packaging, analytical methods, stability data, registration data or know-how of
a proprietary or confidential nature relating to the Product or Active
Ingredient disclosed by the other party pursuant to or in connection with this
Agreement (the "Proprietary Information"); provided, however, that the term
"Proprietary Information" does not include information which becomes available
to the receiving party following the date of this Agreement on a
non-confidential basis from a source other than the disclosing party, its
representatives or Affiliates, if such source is not under an obligation,
(whether contractual, legal or fiduciary) to the disclosing party, its
representatives or its Affiliates to keep such information confidential.

         6.2      Survival of Confidentiality. PURCHASER and SUPPLIER hereby
agree that the provisions of this Article 6 and the obligations of
confidentiality herein will endure for a period of five (5) years after the
expiration or termination of this Agreement; provided, however, that with
respect to Proprietary Information regarding, arising out of, relating to,
reflecting, incorporating or based upon scientific, technological (including,
without limitation, analytical, manufacturing or formulation technology),
regulatory or compliance matters, the obligations of confidentiality herein will
not terminate.

7.       INDEMNIFICATION.

         7.1      Indemnification of SUPPLIER. PURCHASER will defend, indemnify,
and hold harmless SUPPLIER, its officers, agents, employees and Affiliates from
any loss, claim, action, damage, penalty, fine, expense or liability (including
reasonable defense costs and attorneys fees) ("Claim") to the extent the same
arises out of or is related to (a) the breach of any representation, warranty or
guarantee made by PURCHASER herein, (b) the handling, possession or use of the
Product following delivery to PURCHASER in accordance with Section 3.1
including, without limitation, express and implied warranties of
merchantability, fitness for a particular purpose and strict liability, unless
the claim results from the applicable Product failing


<PAGE>   78

to conform to the Specifications, where such non-compliance is due solely to the
actions or omissions of SUPPLIER or (c) any other negligent act or omission of
PURCHASER.

         7.2      Indemnification of PURCHASER. SUPPLIER will defend, indemnify,
and hold harmless PURCHASER, its officers, agents, employees and Affiliates from
any Claim to the extent the same arises out of or is related to (a) the breach
of any representation, warranty or guarantee made by SUPPLIER herein or (b) any
other negligent act or omission of SUPPLIER.

         7.3      Indemnification Procedures. In any case under this Agreement
where one party has indemnified the other against any claim or legal action,
indemnification will be conditioned on compliance with the procedure outlined
below. Provided that prompt notice is given of any claim or suit for which
indemnification might be claimed, the indemnifying party promptly will defend,
contest or otherwise protect against any such claim or suit (including by way of
settlement and release) at its own cost and expense. The indemnified party may,
but will not be obligated to, participate at its own expense in a defense
thereof by counsel of its own choosing, but the indemnifying party will be
entitled to control the defense unless the indemnified party has relieved the
indemnifying party from liability with respect to the particular matter. If the
indemnifying party fails timely to defend, contest or otherwise protect against
any such claim or suit, the indemnified party may, but will not be obligated to,
defend, contest or otherwise protect against the same, and make any compromise
or settlement thereof and recover the entire costs thereof from the indemnifying
party, including reasonable attorneys fees, disbursements and all amounts paid
as a result of such claim or suit or the compromise or settlement thereof;
provided, however, that if the indemnifying party undertakes the timely defense
of such matter, the indemnified party will not be entitled to recover from the
indemnifying party its costs incurred in the defense thereof. The indemnified
party will cooperate and provide such assistance as the indemnifying party may
reasonably request in connection with the defense of the matter subject to
indemnification.

8.       RECALLS.

         8.1      Recalls. If any Product must be recalled by reason of failure
to meet the Specifications, any requirements of any applicable Governmental or
Regulatory Authority or any other requirements of law, PURCHASER will pay all
costs and expenses in order to effect the recall unless such recall is caused by
a failure of the Product to meet the Specifications, where such failure is due
solely to the actions or omissions of SUPPLIER. However, SUPPLIER will, in any
event, comply with any regulatory obligations arising from its status as
manufacturer of the recalled Product, and otherwise cooperate as reasonably
required in PURCHASER's efforts.

         8.2      Reimbursement by PURCHASER. PURCHASER will reimburse SUPPLIER
for any costs reasonably expended by SUPPLIER to effect the recall, including
any cost associated with the Product that cannot be shipped due to the condition
requiring the recall, unless the recall is required due to the failure of the
Product to meet the Specifications, where such failure is due solely to the
actions or omissions of SUPPLIER.

         8.3      Reimbursement by SUPPLIER. If PURCHASER can demonstrate that
the failure to meet applicable legal requirements is caused by failure of the
Product to meet the Specifications, where such failure is due solely to the
actions or omissions of SUPPLIER, SUPPLIER will reimburse PURCHASER for (a) any
cost reasonably expended by PURCHASER to effect the recall and (b) the
Reimbursement Amount in accordance with Section 5.4.

sufficient to substantiate and verify its duties and obligations hereunder,
including but not limited to, records of orders sent and received, Product
manufactured, work in progress, Product analyses and quality control tests,

will destroy any records relating to regulatory compliance or quality assurance
without giving the other party advance written notice and an opportunity to take
possession of or copy such records.

         9.2      Notice of Governmental or Regulatory Authority Actions. Each
party agrees to advise the other party in a timely manner of any actions by any
Governmental or Regulatory Authority with respect to the Product. Such notice
remains subject, in all respects, to the provisions of Article 6.

10.      TERM AND TERMINATION.

         10.1     Term. Subject to the termination provisions of Section 10.2,
this Agreement will expire on the date (the "Termination Date") which is two
years from the Effective Date. PURCHASER shall have the option, by providing
SUPPLIER with at least 90 days' prior written notice of the Termination Date, to
extend the term of this Agreement for an additional one year period, provided
PURCHASER has used good faith efforts to arrange for an alternative source of
supply of the Product and Active Ingredient. In the event PURCHASER elects to
extend this Agreement for an additional one year period, the parties shall
commence good faith negotiations regarding terms and conditions for the
continued supply of Active Ingredient or Product by SUPPLIER.

         10.2     Termination. PURCHASER shall have the right to terminate this
Agreement upon 60 days' prior written notice to SUPPLIER. In addition, each
party will have the right to terminate this Agreement (i) by giving the other
party written notice thereof if the other party fails to perform or violates any
material provision of this Agreement in any material respect, and such failure
continues unremedied for a period of thirty (30) days after the date the
notifying party gives written notice to the defaulting party with respect
thereto; or (ii) immediately if the other party is declared insolvent or
bankrupt by a court of competent jurisdiction, or a voluntary petition of
bankruptcy is filed in any court of competent jurisdiction by the other party,
or the other party makes or executes any assignment for the benefit of
creditors.

         10.3     Effect of Termination. Unless otherwise agreed to between the
parties, all Raw Materials, Active Ingredient, work in progress or Product on
hand as of the effective date of expiration or termination of this Agreement
will be treated as follows as soon as practicable following such expiration or
termination:

         (a)      Raw Materials presently owned by SUPPLIER, as set forth on
                  Schedule D hereto, or otherwise purchased by SUPPLIER
                  reasonably based on any purchase orders for Product or Active
                  Ingredient submitted by PURCHASER, and not utilized by
                  SUPPLIER for the manufacture of the Product up to and
                  including
<PAGE>   80

                  the date of such expiration or termination, shall be delivered
                  by SUPPLIER to PURCHASER, whereupon PURCHASER will pay
                  SUPPLIER therefor in accordance with the costs set forth on
                  Schedule D or in an amount equalling SUPPLIER's actual cost
                  for such materials as documented by SUPPLIER to PURCHASER;

         (b)      Work in progress commenced by SUPPLIER in accordance with this
                  Agreement will, at the option of PURCHASER (but at the option
                  of either party in the case of termination hereof by it under
                  Section 10.2), (i) cease, and such work in progress will
                  remain with SUPPLIER (in which case PURCHASER will pay
                  SUPPLIER an amount equal to SUPPLIER's actual costs incurred
                  in connection with the performance and cessation of such work
                  less the cost to SUPPLIER of materials that can be returned by
                  SUPPLIER or used by SUPPLIER in later batches of other
                  products manufactured by SUPPLIER as reasonably determined by
                  SUPPLIER) or (ii) be completed by SUPPLIER and delivered to
                  PURCHASER, whereupon PURCHASER will pay SUPPLIER therefor in
                  accordance with the terms hereof; provided, however, that in
                  the case of expiration under Section 10.1, PURCHASER will not
                  have such option and will proceed under clause (ii) of this
                  provision; and

         (c)      Active Ingredient and Product manufactured pursuant to
Schedule C and the Production Schedule, respectively, will be delivered by
SUPPLIER to PURCHASER, whereupon PURCHASER will pay SUPPLIER therefor in
accordance with the terms hereof.

         10.4     No Release. The expiration or termination of this Agreement
will not operate to release any party from any liability incurred prior to or
upon termination hereof or which subsequently arises under the operation of
Article 22.

         11.1     Compliance. Each party will provide reasonable assistance to
the other if necessary to respond to any Governmental or Regulatory Authority

will at all times adhere to safety regulations, GMPs and work schedules
generally applicable to SUPPLIER's own employees.

         11.2     Compliance Audits. Each party will notify the other party
within forty-eight (48) hours after it receives notice of a Governmental or

by virtue of this Agreement or the performance by SUPPLIER of services
hereunder; provided, however, that SUPPLIER will permit PURCHASER to use

to be sold in the U.S., PURCHASER shall be solely responsible for ensuring that
approved Product labels, Product inserts and other printed materials, if any,
comply with all applicable laws, provided, however, that SUPPLIER warrants that
Product supplied hereunder prior to the conversion of labels to PURCHASER's name
and trademark in accordance herewith shall comply with the applicable Marketing
Authorization as it exists on the date hereof.

shall allow such transition to occur prior to the end of the Transition Period.
SUPPLIER will, or will cause its Affiliates to, affix labeling to the Product to
be sold outside of the U.S. as instructed by PURCHASER. PURCHASER shall pay all
costs incurred by SUPPLIER in connection with the implementation of such labels
bearing PURCHASER's name and trademark for Product to be sold outside of the
U.S. From and after the change of such labels and tradedress, nothing contained
herein will give PURCHASER any right to use any SUPPLIER trademark and PURCHASER
will not obtain any right, title or interest in any SUPPLIER trademark by virtue

to be sold outside of the U.S., PURCHASER shall be solely responsible for
ensuring that approved Product labels, Product inserts and other printed

PURCHASER will reimburse SUPPLIER for any increased costs that SUPPLIER

Active Ingredient, or operating the respective facilities in which the Product
or Active Ingredient is manufactured, as a result of any change in such laws or
regulations.

such debarment or conviction. The terms of the preceding sentence shall survive
the termination or expiration of this Agreement.

         (e)      The Product shall, at the time it is delivered under Section

for its indicated purpose) bearing PURCHASER's name and trademarks by or on
behalf of PURCHASER or its customers will not infringe any trademark or trade
name of any third person.

         (c)      PURCHASER will comply in all material respects with any law,

between WILLIAM K. SUMMERS, M.D., an individual having his principal place of

                              W I T N E S S E T H:

         WHEREAS, SUMMERS is the owner of the Licensed Patents (as hereinafter
defined) and has developed and is the owner of the Agreement Compound Studies
(as hereinafter defined);

         WHEREAS, pursuant to the License Agreement, SUMMERS granted LICENSOR
an exclusive license under the Licensed Patents throughout the world (except
Canada where SUMMERS may wish to grant a license to LICENSOR and to
PharmaScience Inc., a Canadian corporation ("PharmaScience"));

         WHEREAS, on the date hereof, LICENSEE has purchased from LICENSOR,
pursuant to the Asset Purchase Agreement dated April 14, 2000, certain assets
relating to the Cognex(R) business and LICENSOR has agreed to sublicense the
Licensed Patents to LICENSEE pursuant to Section 2.1 thereof;

         NOW, THEREFORE, in consideration of the mutual covenants herein
contained, LICENSOR and LICENSEE agree as follows:

I.  DEFINITIONS

The following terms as used in this Agreement shall have the meanings set forth
in this Article:

         1.01 "Affiliate", with respect to any Person, means any other Person
controlling, controlled by or under direct or indirect common control with such
Person in question. A Person shall be deemed to control a corporation (or other
entity) if such Person possesses, directly or indirectly, the power to direct
or cause the direction of the management and policies of such corporation (or
other entity), whether through the ownership of voting securities, by contract,
or otherwise.

         1.02 "Agreement Compound" means the pharmaceutical compound
1,2,3,4-tetrahydro-9-aminoacridine (known by the generic names "Tacrine" and
"THA"), including all salts and hydrates.

                                       1
<PAGE>   94

         1.03 "Agreement Compound Studies" means all Data together with all of
SUMMER's protocols, write-ups, analyses, compilations and other writings
relating to the Data in whatever stage of completion and whether in preparation
for submission to regulatory authorities or otherwise.

         1.04 "Data" means, whether generated by SUMMERS or any of SUMMER's
researchers or investigators, all preclinical (including, but not limited to,
chemistry, formulation stability and analytical development methodology),
clinical, toxicology and other data (including, but not limited to, raw and
underlying data such as patient records, computer software, adverse events
data, etc.) resulting from, referring, or relating to, all studies performed or
to be performed or completed by or on behalf of SUMMERS in connection with
Agreement Compound.

         1.05 "Exclusivity Period" means, with respect to a given country, the
period of time during which no third party can obtain governmental approval to
sell Agreement Compound based, in whole or in part, on data submitted by
LICENSOR to obtain its approval to sell Agreement Compound in said country.

         1.06 "Licensed Compound" means Agreement Compound which (or the use or
sale of which) is covered by a Valid Claim.

States Patent and all patents issuing from corresponding applications in
countries outside the United States, and any and all reissues, reexaminations,
extensions, substitutions, confirmations, registrations, revalidations,
additions, continuations, continuations-in-part or divisions of or to any of
the aforesaid patents. If a particular patent or patent application is directed
toward an invention of general applicability to all pharmaceuticals or
pharmaceuticals across a broad range of therapeutic areas, it would not be
deemed to be covered within the definition of "Licensed Patents" because such
patent or patent application may have incidental applicability to Agreement
Compound.

         1.08 "Losses" means any and all damages, fines, fees, penalties,
deficiencies, losses and expenses (including without limitation interest, court
costs, reasonable fees of attorneys, accountants and other experts or other
expenses of litigation or other proceedings or of any claim, default or
assessment).

         1.09 "NDA" means the United States New Drug Application filed by the
LICENSOR on June 1, 1990 (NDA #20-070) in connection with the use of Agreement
Compound for the treatment of Alzheimer's disease.

         1.10 "Net Sales" means the actual gross sales of Licensed Compound and
Products by LICENSEE and its Affiliates to nonaffiliated customers less trade,
cash and quantity discounts and broker's or agent's commissions, if any,
actually allowed or paid; returns, allowances and adjustments actually granted
customers; prime vendor and institutional rebates; freight insurance and other
transportation costs and all taxes (except income taxes), tariffs, duties and
other similar governmental charges paid by LICENSEE, its Affiliates or
sublicensees. In the event of sale of Products containing Licensed Compound in
combination with other active ingredients, the Net Sales for such products
shall be determined by multiplying what would otherwise be the Net Sales of
such products by a fraction, the numerator of which shall be the production
cost of Licensed Compound contained therein

                                       2
<PAGE>   95

and the denominator of which shall be the total production cost of all active
ingredients contained therein, the production cost of each to be determined
using the standard production cost formula of LICENSEE, provided, however, that
in no event shall the Net Sales for combination products be reduced by more
than sixty-five percent (65%).

         1.11 "Payable Royalties" means the amount of royalties calculated to
be paid by LICENSEE, its Affiliates or sublicensees pursuant to this Agreement
reduced by (a) any amounts paid to third parties pursuant to Section 3.08 and

combination form which (or the use or sale of which) is covered by a Valid
Claim.

         1.14 "United States Patent" means United States Patent No. 4,816,456
and any reexaminations or reissues thereof.

         1.15 "Valid Claim" means a claim which but for the license granted
hereunder, would be infringed by LICENSOR's, its Affiliate's or sublicensee's
manufacture, use or sale of Product and/or Licensed Compound, and which is in
an unexpired issued patent owned by SUMMERS included within the Licensed
Patents which has not been held invalid or unenforceable by a decision of a
court of competent jurisdiction, unappealable or unappealed within the time
allowed for appeal, and which has not been held by an applicable governmental
agency, or expressly admitted in writing by the owner, to be invalid through
reissue, reexamination, disclaimer or otherwise, and, in the case of a holding,
is unappealable or unappealed within the time allowed for appeal.


II.  GRANT

         2.01 Grant of License. LICENSOR hereby grants to LICENSEE an exclusive
sublicense (and the right to sublicense) under the Licensed Patents to make,
use, and sell Licensed Compound and Products in all countries of the world;
provided, however, that SUMMERS may, in addition to the license granted to
LICENSOR in Canada, grant a nonexclusive license (without the right to
sublicense) under the Canadian Licensed Patents to PharmaScience for the sole
purpose of making, using, and selling Licensed Compound and Product in Canada
without the right to send Agreement Compound and/or Product outside of Canada.
To the extent Net Sales are made by any sublicensee of LICENSEE, they will be
treated for royalty purposes as if made by LICENSEE.

         2.02 Sublicense Subject To License. LICENSEE acknowledges that, as a
licensee under the License Agreement, LICENSOR can not sublicense to LICENSEE
rights other than those it has been granted under the License Agreement.

license to LICENSEE and the further covenants contained in this Agreement,
including the covenant contained in Section [****]-CONFIDENTIAL TREATMENT
REQUESTED

                                       3
<PAGE>   96

6.03(a), LICENSEE shall pay to LICENSOR's Designee the amounts set forth below
pursuant to the terms set forth herein.

         3.02 In the event that SUMMERS, without LICENSOR's prior written
consent and unless compelled by applicable court or agency order, takes an
affirmative action that permits a third party (other than PharmaScience in
Canada) to make, use or sell Product or Agreement Compound in any country such
that LICENSEE does not have an exclusive market in such country for Product or
Agreement Compound (i.e. SUMMERS disclaims a Licensed Patent, or grants a
license to, covenants not to sue, or otherwise agrees not to enforce a Licensed
Patent or indemnifies a third party), LICENSOR shall pay to LICENSEE an amount
equal to all amounts recovered by LICENSOR pursuant to Section 3.02 of the
License Agreement, less reasonable costs and expenses of LICENSOR in effecting
such recovery. LICENSOR shall use its commercially reasonably efforts to
recover what it is entitled to under Section 3.02 of the License Agreement.
LICENSOR agrees that any request by SUMMERS pursuant to Section 3.02 of the
License Agreement will be communicated to LICENSEE in writing promptly and that
LICENSOR shall not consent or object without direction to so do from LICENSEE.

         3.03 Royalty. (a) In further consideration of the rights granted
hereunder, LICENSEE shall pay to LICENSOR's Designee from June 1, 2000, and for
the remaining term of this Agreement, except as hereinafter provided, the
following royalties:

                  (1)  [INTENTIONALLY OMITTED]

                  (2) [*****] of Net Sales in the United States, until the date
         of expiration of the United States Patent;

                  (3) In each country outside the United States where there is
         a Licensed Patent, [*****] of Net Sales in said country; such
         royalties shall continue thereafter until the end of the Exclusivity
         Period in said country; and

                  (4) Beginning with the end of the Exclusivity Period in each
         country outside the United States where there is a Licensed Patent,
         [*****] of Net Sales in said country; such royalties shall continue
         thereafter until the date of expiration of the applicable Licensed
         Patent.

         (b) Notwithstanding the foregoing, the amount of Payable Royalties in
any quarter shall be reduced by any and all Prepaid Royalties until such time
that all Prepaid Royalties have been credited against Payable Royalties. As
used herein, "Prepaid Royalties" means royalties in the amount of $[*****] that
were prepaid by LICENSOR to SUMMERS, less an amount equal to the amount of
royalties payable by LICENSOR to SUMMERS under the License Agreement for the
period beginning April 1, 2000 and ending May 31, 2000.

         (c) For purposes of this Agreement, and in response to the advice of
the United States Federal Trade Commission in connection with the approval of
the merger of LICENSOR and Pfizer Inc., LICENSOR irrevocably appoints Dr.
William K. Summers as its Designee (where indicated) for purposes of Articles
III and IV of this Agreement.

         3.04 Payment. (a) All payments to be made by LICENSEE to LICENSOR's
Designee hereunder shall be made as follows:

         [*****]

The payment pursuant to clause (a)(ii) is mandated by a Stipulation and Order
Re Enforcement of Judgment and, by order of the Superior Court of the State of
California for the County of Los Angeles, may not be revoked by SUMMERS for any
reason.

         (b) All payments to be made by LICENSEE as provided in Section 3.04(a)
above shall be made in United States dollars in the United States. For
converting into United States dollars a royalty accrued in another currency,
the conversion rate shall be the closing commercial buying rate of exchange for
United States dollars and such other currency quoted by Citibank, N.A. (or its
successors in interest) in New York for the last business date of the quarterly
period for which payment is being made.

         3.05 Taxes Withheld. Any income or other tax that LICENSEE or its
Affiliates is required to withhold and pay on behalf of LICENSOR's Designee
with respect to the royalties payable to LICENSOR's Designee under this
Agreement shall (without regard to the provisions of Section 3.03(b)) be
deducted from such royalties prior to remittance to LICENSOR's Designee.
LICENSEE shall provide LICENSOR's Designee with documentary evidence of said
payments.

         3.06 Computation of Royalties. All sales of Product and Licensed
Compound between LICENSEE and any of its Affiliates and/or sublicensees shall
be disregarded for purposes of computing royalties under this Article III.
Nothing herein contained shall obligate LICENSEE to pay LICENSOR's Designee
more than one royalty on any unit of a Product.

         3.07 Licenses to Affiliates. (a) LICENSOR shall, at the request of
LICENSEE, sign sublicense agreements directly with LICENSEE's Affiliates in
those countries where the sale of Licensed Compound or Product by LICENSEE or
its Affiliates would infringe a Valid Claim. Such license agreements shall
contain substantially the same language as contained herein with appropriate
changes in parties and territory. It shall be LICENSEE's responsibility to
register such agreements with the appropriate authorities.

         (b) Royalties received by LICENSOR's Designee directly from LICENSEE's
Affiliates pursuant to such agreements shall be credited towards LICENSEE's
royalty obligation under Section 3.03 hereof.

                                       5
<PAGE>   98

         (c) Notwithstanding any other term or provision of this Agreement, the
failure of LICENSOR to comply with the provisions of Section 3.07(a) within
sixty (60) days of a request by LICENSEE or such Affiliate to comply with such
provision, shall immediately release LICENSEE of any and all obligations of
LICENSEE to make payments of any kind, including, but not limited to, payments
pursuant to Sections 3.03 and 6.04, until LICENSOR has complied with such
provisions.

         3.08 Offset of Royalties. LICENSEE shall be entitled to offset against
the royalties otherwise due hereunder any amounts payable to third parties in
respect of other patent rights covering the manufacture, use or sale of
Agreement Compound that would preclude LICENSEE from practicing a Licensed
Patent without obtaining a license thereunder, except royalties due under the
Settlement and License Agreement dated as of September 28, 1994 between
Hoechst-Roussel Pharmaceuticals Inc. and LICENSOR.

         3.09 Reduction of Royalties. (a) In the event that any third party
begins the sale of Product in any country where there is a Licensed Patent and
the sale of Product by all such third parties in the aggregate in such country
reaches or exceeds the percentages set forth below of the sales of Product in
such country made by LICENSEE, its Affiliates and any sublicensees in any
fiscal quarter, then payment of royalties (and the obligation to pay royalties)
shall be reduced with respect to Net Sales in such country pursuant to the
schedule set forth below for so long as such third party sales shall continue.
The amount of aggregate third party sales for a fiscal quarter shall be
determined by LICENSEE (a) in the United States, by data obtained from
Information Management Systems ("IMS") and (b) in any other country in which
there is a Licensed Patent, by data obtained from IMS drugstore audits
supplemented by LICENSEE's sampling of hospital and other institutional
purchasers.

         (b) Upon the resumption of full royalty payment following any
reduction of payment under any Section of this Agreement, no payment shall be
made with respect to any royalties not received during the period of reduction.

         (c) Notwithstanding any other term or provision of this Agreement, the
payment of royalties (and the obligation to pay royalties) shall terminate in
its entirety in a particular country in the event that SUMMERS, without
LICENSOR's prior written consent and unless compelled by applicable court or
agency order, takes an affirmative action that permits a third party (other
than PharmaScience in Canada) to make, use or sell Product or Agreement
compound in such country such that LICENSEE does not have an exclusive market
in such country for Product or Agreement Compound (e.g. SUMMERS grants a
license to, covenants not to sue, or otherwise agrees not to enforce a Licensed
Patent or indemnifies such third party). LICENSOR agrees that any request by
SUMMERS pursuant to Section 3.09(c) of the License Agreement will be
communicated to LICENSEE in writing promptly and that LICENSOR shall not
consent or object without direction to so do from LICENSEE.


IV.  RECORDS AND PAYMENTS

         4.01 Quarterly Reports and Payments. Beginning one hundred and twenty
(120) days after the second fiscal quarter of 2000 and one hundred and twenty
(120) days after the end of any subsequent fiscal quarter during the term of
this Agreement, LICENSEE shall deliver or cause to be delivered to LICENSOR's
Designee and to Burns, Doane, Swecker & Mathis LLP, a written report showing
all sales of Product by LICENSEE and its Affiliates during the preceding
quarterly period and showing the calculation of Net Sales and the amount
payable as royalties as calculated in accordance with Article III hereof,
provided, however, that the first such report shall cover only the month of
June 2000. Concurrently with the submission of each such written report,
LICENSEE shall pay LICENSOR's Designee or cause to be paid the amount of
royalties shown to be due thereon, subject to the other provisions of this
Agreement.

                                       7
<PAGE>   100

         4.02 Records. LICENSEE shall keep or cause to be kept accurate records
in sufficient detail to enable the royalties payable hereunder to be
determined. Upon the request of LICENSOR's Designee (but not more frequently
than once in each fiscal year), LICENSOR's Designee may designate an
independent public accountant mutually acceptable to LICENSOR's Designee and
LICENSEE to review such records to verify the accuracy of the royalty payments
made or payable hereunder during the preceding fiscal year, but only as to any
period ending not more than two (2) years prior to the date of such request.
Said accountant shall not disclose to LICENSOR or any other party any
information except that which should properly be contained in a royalty report
required under this Agreement. LICENSOR's Designee shall pay the cost for any
review of records conducted at the request of LICENSOR's Designee under this
Section 4.02; provided, however, that in the event that such review shall
reveal a discrepancy of greater than twenty percent (20%) in the royalty
payment due to LICENSOR's Designee hereunder, LICENSEE shall pay the cost of
such review. In addition, in the event that LICENSEE seeks indemnification
under Section 9.03 of this Agreement or if LICENSOR reasonably needs access to
such records in connection with any action or proceeding against LICENSOR by
SUMMERS, LICENSOR shall have the right to review LICENSEE's records to verify
the accuracy of the royalty payments made or payable hereunder, upon reasonable
notice and during regular business hours.


V.  PATENT PROSECUTION AND INFRINGEMENT

         5.01 Prosecution. LICENSOR shall use all reasonable measures to cause
SUMMERS to prosecute all applications for Licensed Patents and maintain all
such applications and issued Licensed Patents at his own expense and LICENSOR
shall keep LICENSEE currently advised of all steps taken or to be taken in the
prosecution of such applications (including reissues and reexaminations) and
improvements therein and shall furnish LICENSEE with copies of all such patent
applications and papers received from and filed with each patent office
promptly after filing or receipt. SUMMER's has undertaken in the License
Agreement to take all reasonable and necessary actions to obtain and maintain
Licensed Patents. In the event that SUMMERS elects or has elected not to file
applications in any country or countries or not to continue to prosecute any
application, including an application involved in an appeal or opposition
proceeding, or not to maintain any Licensed Patent or application for Licensed
Patent by failure to pay any required annuity, renewal or working fee, LICENSOR
shall so advise LICENSEE in time to enable LICENSEE to take appropriate action
and LICENSEE shall be entitled to file such applications or take such other
action at its expense and to own such resultant patents without the obligation
to pay any royalties under such patents pursuant to this Agreement or
otherwise. In such event, LICENSOR shall and shall use all reasonable measures
to cause SUMMERS, at LICENSEE's request, but at no additional cost to LICENSEE,
execute whatever documents are necessary to transfer to LICENSEE full ownership
of such application or Licensed Patent. Notwithstanding any other term or
provision of this Agreement, the payment of royalties (and the obligation to
pay royalties) shall terminate in its entirety in a particular country in the
event that SUMMERS fails to comply with the provisions of Section 5.1 of the
License Agreement with respect to such country.

         5.02 Infringement Actions. LICENSOR and LICENSEE shall promptly notify
each other of any infringement of the Licensed Patents which may come to their
attention. SUMMERS, at his sole discretion, may undertake to obtain a
discontinuance of the aforesaid infringement and/or SUMMERS may bring suit
against such infringer.

                                       8

It is understood and agreed that SUMMERS shall bear solely all costs and
expenses associated with any suit or action pursuant to Section 5.02 of the
License Agreement and shall be entitled to retain and keep any and all sums
received, obtained, collected or recovered whether by judgment, settlement or
otherwise, as a result of such suit. SUMMERS shall have the right to prosecute
by counsel of his choice, and in connection therewith shall have the full right
to conduct the prosecution thereof.

VI.  CONFIDENTIALITY AND OTHER OBLIGATIONS

         6.01 Confidentiality. (a) Each party agrees that, without the prior
written consent of the other party or unless required by law, it shall not
disclose to any third party the terms of this Agreement or any confidential
information regarding the other party or the business of such party which has
been made available to it pursuant to Article III or Article IV hereof. It is
understood that LICENSEE and LICENSOR, without the consent of the other party,
may disclose in press releases or to third parties the existence and general
nature of this Agreement without disclosing the specific terms hereof.

         (b) It is further understood that LICENSOR shall not be entitled to
disclose to any third party or to publish for any purpose (scholarly,
educational or otherwise) any Agreement Compound Study or any portion, extract
or analysis (partial or full) thereof without the prior written consent of
LICENSEE. It is understood that such restriction is a worldwide restriction.

If any third party has an obligation to present a document relating to
Agreement Compound to LICENSOR prior to its publication for LICENSOR's comment
and approval, LICENSOR shall give LICENSEE access to such document and assist,
in all respects requested, LICENSEE in communicating to such third party its
comments or concerns relating to the publication of any such document. LICENSEE
may instruct LICENSOR to withhold its approval in the event that, in LICENSEE's
reasonable opinion, its commercial position regarding Product may be prejudiced
by such publication.

         (c) LICENSOR shall take all reasonable measures to restrain SUMMERS,
his employees, agents and advisors and former employees, agents and advisors
from publishing or disclosing to any third party the Agreement Compound Studies
or any portion, extract or analysis (partial or full) thereof.

         (d) LICENSOR shall refrain from making untrue statements regarding
Agreement Compound or Licensed Patents.

         (e) Notwithstanding any other provision of this Section 6.01, LICENSEE
or LICENSOR shall be permitted to respond to any lawful court or other tribunal
demand (including subpoenas, interrogatories, or document requests) seeking
information or documents relating to the validity of the Licensed Patents.

         6.02 Agreement Compound Studies. In addition to the provisions of
Section 6.01(b), LICENSOR shall take all reasonable measures to prevent SUMMERS
from selling or conveying the Agreement Compound Studies to any third party or
allowing the Agreement Compound Studies to be used by any third party for
purposes of gaining approval for any Person other than LICENSEE from any
governmental body to market Agreement Compound or Product. LICENSEE shall not
sell or convey its equivalent of the Agreement Compound Studies (the "Licensee
Studies") to any third party nor allow the Licensee Studies to be used by any
third party for purposes of gaining approval for any

                                       9
<PAGE>   102

such third party from any governmental body to market Licensed Compound or
Product unless the sales by such third party are included in the calculation of
Net Sales.

         6.03 Non-Competition. (a) During the term of this Agreement, LICENSOR
shall not assist and shall use all reasonable measure to prevent SUMMERS from
assisting (other than PharmaScience with respect to Canada only) any third
party to develop, register, promote or market Agreement Compound or Product.

         (b) During the term of this Agreement, LICENSEE shall not assist any
third party to develop, register, promote or market Licensed Compound or
Product where the sale or use of Product or Licensed Compound is covered by a
Licensed Patent; provided, however, that LICENSEE is permitted to assist a
third party if the sales of such third party, if any, are included in the
calculation of Net Sales.

         (c) Notwithstanding any other term or provision of this Agreement, the
payment of royalties shall terminate in its entirety in the event that LICENSOR
breaches the obligations of Section 6.03(a) or SUMMERS breaches the obligations
of Section 6.03(a) of the License Agreement.

         6.04 Activities of LICENSEE. It is understood that LICENSEE regularly
has discussions with other Persons with respect to licensing and related
activities with respect to pharmaceutical products, including those in the
field of cognition, as a result of which LICENSEE may, during the term of this
Agreement, market products (not containing Licensed Compound) that will compete
with Product. In the event that during the term of this Agreement LICENSEE
commences the sale or promotion in the United States of a product (other than
Product) for the treatment of Alzheimer's Disease and at the time of such
commencement the payment of royalties due under this Agreement for Net Sales in
the United States has not been reduced by more than twenty-five percent (25%)
or terminated pursuant to Section 3.09 hereof or otherwise, LICENSEE will pay
to LICENSOR's Designee a one-time payment of one million dollars
($1,000,000.00). This payment is in full and complete compensation for any loss
of royalties to LICENSOR's Designee that might be caused by LICENSEE's sale of
competing product(s) inside or outside the United States. Payment of the amount
due under this Section 6.04 shall not relieve LICENSEE of the obligations to
pay royalties on this sale of Product pursuant to the terms of this Agreement.
Notwithstanding the foregoing, if LICENSOR incurs the obligation under the
terms of Section 6.04 of the License Agreement to make payment to SUMMERS,
LICENSEE shall not be obligated to make any payment pursuant to this Section
6.04, as it is a one-time payment.

which either party may terminate this Agreement.

         8.03 Continuing Rights. Termination of this Agreement for any reason
shall be without prejudice to:

         (a) LICENSOR's right to receive all royalties accrued and unpaid and

this Agreement on the effective date of such termination;

                          TRANSITION SERVICES AGREEMENT

         TRANSITION SERVICES AGREEMENT, dated May ___, 2000, between FIRST
HORIZON PHARMACEUTICAL CORPORATION, a corporation organized and existing under
the laws of Delaware, whose principal office is located at 660 Hembree Parkway,
Suite 106, Roswell, Georgia 30076 ("Horizon"), and WARNER-LAMBERT COMPANY, a
corporation organized and existing under the laws of Delaware, whose principal
office is located at 201 Tabor Road, Morris Plains, New Jersey 07950
("Warner-Lambert"). All capitalized terms not otherwise defined herein shall
have the meanings ascribed to them in the Asset Purchase Agreement, dated as of
April 14, 2000 (the "Purchase Agreement"), by and between Warner-Lambert and
Horizon.

                                   WITNESSETH:


         WHEREAS, pursuant to the Purchase Agreement, Warner-Lambert has agreed
to sell and Horizon has agreed to purchase the Assets;

         WHEREAS, it is a condition to the consummation of the transactions
contemplated by the Purchase Agreement that Warner-Lambert and Horizon enter
into this Agreement;

         WHEREAS, the parties wish to facilitate an orderly transfer of the
Cognex business to Horizon; and

         WHEREAS, Warner-Lambert and certain of its Affiliates (the "Service
Providers") are willing to provide certain transitional administrative services
to Horizon upon the terms and conditions set forth below;

         NOW THEREFORE, in consideration of the mutual covenants and agreements
set forth in this Agreement, the parties hereto agree as follows:

have the meanings set forth below:

         "Business" means the Cognex business in the European countries in the

                                       1
<PAGE>   113



Article 2.   Services.

         2.1      Services to be Made Available. In accordance with the terms
and provisions of this Agreement, Warner-Lambert agrees to provide or cause to
be provided to Horizon the transitional services relating to the Business that
are described on Schedule A hereto (collectively, the "Services") for the term
of this Agreement. Except as may be agreed by Warner-Lambert, provision of each
such Service will be limited to substantially the same number and quality of
employees as are currently involved in the conduct of the Business.

         2.2      Controlling Provisions. In ordering and delivering Services
and Incremental Services hereunder, Warner-Lambert, the Service Providers and
Horizon may employ their standard forms, but nothing in those forms will be
construed to modify or amend the terms of this Agreement and in case of conflict
herewith, this Agreement will control.

         2.3      Cash Management. In the event that provision of any of the
Services requires Warner-Lambert or any Service Provider to receive cash or
other moneys on behalf of Horizon, Warner-Lambert will utilize or cause to be
utilized commercially reasonable efforts to assure that such cash or other
moneys are promptly credited to one or more accounts designated by Horizon.
Horizon agrees that payments to Horizon may be made in local currency and that
if Horizon elects to receive payment in any currency other than the currency of
payment, Horizon bears all currency exchange costs and risk related thereto.

Article 3.  Title to Equipment and Media.

         3.1      Property of Warner-Lambert. Unless furnished to Warner-Lambert
or any Service Provider by Horizon, all equipment used in connection with
providing the Services and all media upon which information of Horizon is stored
in connection with the Services is and will remain the property of
Warner-Lambert or the relevant Service Provider.

Article 4.  Intentionally Omitted.

Article 5.  Billing.

         5.1      Fees. Services relating to the maintenance of the Business in
the ordinary course will be provided to Horizon for the term of this Agreement,
free of charge.

         5.2      Incremental Services and Out-of-Pocket Expenses. (a) Horizon
will be charged, per hour, the amount shown in Schedule A for the Incremental
Services referred to therein, plus applicable value added taxes; provided,
however, Horizon will not be charged for Incremental Services to the extent such
Incremental Services are required solely as a result of a breach of this
Agreement by Warner-Lambert or the Service Providers. As used herein,
"Incremental Services" means Services that would not, in the ordinary course of
business, be required to operate the Business, including, but not limited to
responding to investigations by Governmental or Regulatory Authorities regarding
the Product. Horizon will have the option of terminating an Incremental Service
and its corresponding fees, as set forth in Schedule A hereto, upon seven (7)
days' written notice to Warner-Lambert.

                  (b)      Horizon will be charged for all of Warner-Lambert's
and the Service Providers' unrelated third-party out-of-pocket expenses,
reasonably incurred in connection with providing the Services and Incremental
Services; provided, however, Horizon will not be charged for any such unrelated
third-party out-of-pocket


                                       2
<PAGE>   114


expenses to the extent such unrelated third-party out-of-pocket expenses
resulted solely from a breach of this Agreement by Warner-Lambert or the Service
Providers. Before incurring any single such expense in excess of the local
equivalent of U.S.$5,000, Warner-Lambert will notify Horizon or cause Horizon to
be notified. Horizon promptly will approve or reject such expense. If Horizon
rejects such expense, Warner-Lambert will be released from all obligations to
provide any Services or Incremental Services reasonably dependent upon the
activities related to such expense.

                  5.3      Payment. Unless otherwise agreed, Warner-Lambert will
issue or cause to be issued a monthly invoice (the "Invoice(s)") for the fees
relating to Incremental Services rendered pursuant to this Agreement and for
reimbursement of any third party, out-of-pocket expense incurred in connection
with providing the Services or Incremental Services (which invoice will include
copies of all third party invoices that exceed the local equivalent of
U.S.$5,000) and Horizon will pay or cause to be paid such Invoice to an account
designated by Warner-Lambert in immediately available funds within thirty (30)
days from the date of invoice. Unless Horizon specifically objects in writing,
Warner-Lambert will be entitled to cause any Invoice that is unpaid within such
thirty (30) day period to be paid from funds of any Horizon account that
Warner-Lambert may manage on Horizon's behalf hereunder. Horizon acknowledges
that the out-of-pocket expenses will be incurred in local currency, and the
terms of reimbursement thereof in any alternative currency shall be subject to
the agreement of Warner-Lambert.

Article 6.  Indemnification.

         6.1      Indemnification by Horizon. Horizon will indemnify and hold
Warner-Lambert and its respective Affiliates, agents, directors, officers,
employees and representatives harmless from and against any and all Losses which
they may at any time incur by reason of any Action brought by any Governmental
Authority or other third party arising out of or resulting from (a) any
misrepresentation, breach of warranty or non-fulfillment of or failure to
perform any agreement or covenant made by Horizon in this Agreement, (b) any
negligent act or omission of Horizon or any of its Affiliates and (c) provision
of the Services or Incremental Services, provided that in providing the Services
or Incremental Services Warner-Lambert employs at least the same level of care
as it currently employs in providing similar services for its own businesses.

         6.2      Indemnification by Warner-Lambert. Warner-Lambert will
indemnify and hold Horizon and its respective Affiliates, agents, directors,
officers, employees and representatives harmless from and against any and all
Losses which they may at any time incur by reason of any Action brought by any
Governmental Authority or other third party arising out of or resulting from any
misrepresentation, breach of warranty or non-fulfillment of or failure to
perform any agreement or covenant made by Warner-Lambert in this Agreement;
provided, however, that with respect to the provision of Services or Incremental
Services, Warner-Lambert will be liable only to the extent of its failure to
employ at least the same level of care as it employs in providing similar
services for its own businesses or the gross negligence or willful misconduct of
Warner-Lambert.

         6.3      Indemnification Procedures. Indemnification under Section 6.1
or Section 6.2 will be conditioned on compliance with the procedure outlined
below. Provided that prompt notice is given of any claim or suit for which
indemnification might be claimed, the indemnifying party promptly will defend,
contest or otherwise protect against any such claim or suit (including by way of
settlement and release) at its own cost and expense. The indemnified party may,
but will not be obligated to, participate at its own expense in a defense
thereof by counsel of its own choosing, but the indemnifying party will be
entitled to control the defense unless the indemnified party has relieved the


                                       3
<PAGE>   115


indemnifying party from liability with respect to the particular matter. If the
indemnifying party fails timely to defend, contest or otherwise protect against
any such claim or suit, the indemnified party may, but will not be obligated to,
defend, contest or otherwise protect against the same, and make any compromise
or settlement thereof and recover the entire costs thereof from the indemnifying
party, including reasonable attorneys fees, disbursements and all amounts paid
as a result of such claim or suit or the compromise or settlement thereof;
provided, however, that if the indemnifying party undertakes the timely defense
of such matter, the indemnified party will not be entitled to recover from the
indemnifying party its costs incurred in the defense thereof. The indemnified
party will cooperate and provide such assistance as the indemnifying party may
reasonably request in connection with the defense of the matter subject to
indemnification.

         6.4      Disclaimer. Except as expressly provided herein, the Services
and Incremental Services are provided "as is" and without any express or implied
warranties, including the warranties of merchantability and fitness for a
particular purpose.

         6.5      Certain Losses. Under no conditions will Warner-Lambert be
liable for any special, incidental or consequential damages (including, without
limitation, loss of business, profits or good will) in connection with its
performance under this Agreement.

         6.6      Survival. The provisions of this Article 6 will survive the
expiration or earlier termination of this Agreement for so long as an
indemnified party hereunder may have liability under applicable Law.


Article 7.  Term; Termination.

         7.1      Term. This Agreement will expire on November 30, 2000, or
earlier upon termination of all Services and Incremental Services pursuant to
Section 7.2.

         7.2      Termination. (a) In the event that either party materially
fails to perform any of its duties or obligations pursuant to this Agreement and
such failure is not cured within thirty (30) days after notice to such party
specifying the nature of such material failure, the other party may terminate
this Agreement upon further notice to the defaulting party.

                  (b)      Horizon may terminate this Agreement upon thirty (30)
days' prior written notice to Warner-Lambert. Horizon will be relieved of any
obligation to pay for terminated Services and Incremental Services from and
after the effective date of such termination; provided, however, that Horizon
will continue to pay for any noncancellable commitments reasonably made by
Warner-Lambert in anticipation of providing the Services as required herein.
Warner-Lambert agrees to use its commercially reasonable efforts to provide
Horizon with a list of any such noncancellable commitments at least seven (7)
days prior to the termination of the Agreement by Horizon.

                  (c)      Either party may, in its discretion and without
prejudice to its other rights and remedies at law, terminate this Agreement
immediately in the event that the other party becomes insolvent, has a receiver,
examiner or liquidator appointed over the whole or any part of its assets, has
an order made or resolution passed for it to be wound up or enters into any
arrangement or composition with its creditors.


                                       4
<PAGE>   116


                  (d)      Warner-Lambert may terminate this Agreement if any
entity or person (other than Horizon or any of its Affiliates) acquires
ownership or control of 50% or more of Horizon's voting capital stock or
substantially all of its assets.

         7.3      Effect of Termination. (a) Expiration or termination of this
Agreement for any reason, will not release either party from any liability which
at said time it has already incurred to the other party, nor affect in any way
the survival of any rights, duties or obligations of either party that are
expressly stated elsewhere in this Agreement to survive said expiration or prior
termination. Nothing in the immediately preceding sentence will affect the right
of the party aggrieved by any breach of this Agreement to be compensated for any
injury or damage resulting therefrom that is incurred before or after such
expiration or termination.

                  (b)      Upon expiration or termination of this Agreement, all
fees owed by Horizon to Warner-Lambert for Services and Incremental Services
provided through the date of such expiration or termination will be paid within
thirty (30) days of the date of such expiration or termination.

                  (c)      Promptly after the expiration or earlier termination
of this Agreement, Warner-Lambert will deliver or make available to Horizon all
of the Business Data, and if at any time after the termination of this Agreement
Warner-Lambert discovers in its possession or under its control any other
Business Data, it will forthwith deliver such Business Data to Horizon.
Notwithstanding the foregoing, to the extent any of the Business Data are items
susceptible to duplication and are either (x) used in connection with any of
Warner-Lambert's businesses other than the Business or (y) are required by Law
to be retained by Warner-Lambert, Warner-Lambert may deliver photostatic copies
or other reproductions from which, in the case of Business Data referred to in
clause (x).

Article 8.  Miscellaneous.

         8.1      Further Assurances. Subject to the provisions hereof, each of
Warner-Lambert and Horizon will execute and deliver such other agreements,
documents or instruments and take or cause to be taken such other actions as may
be reasonably required in order to effect the purposes of this Agreement and to
consummate the transactions contemplated hereby. Subject to the provisions
hereof, each of Warner-Lambert and Horizon will, in connection with entering
into this Agreement, performing its obligations hereunder and taking any and all
actions relating hereto, comply with all applicable Laws, obtain all required
consents and approvals and make all required filings with any Governmental
Authority and promptly provide the other with all such information as the other
party may reasonably request in order to be able to comply with the provisions
of this sentence.

         8.2      Notices. All demands, notices, requests and other
communications hereunder must be in writing and will be deemed to have been duly

                  Attention: Chief Financial Officer
                  Fax No: (770) 442-9594

         a copy of all notices and communications hereunder having the effect of
         amending, supplementing, modifying or assigning this Agreement shall be
         provided to:

                  Warner-Lambert Company
                  201 Tabor Road
                  Morris Plains, New Jersey 07950
                  Attention:        Senior Vice President and General Counsel
                  Facsimile No. (973) 385-3927

or to such other address as a party hereto shall specify to the other party
hereto in writing.

         8.3      Confidentiality. All confidential information of
Warner-Lambert disclosed to Horizon or any of its Affiliates in connection
herewith and all confidential information of Horizon and its Affiliates
disclosed to Warner-Lambert or its Service Providers in connection herewith will
be held in confidence and will not be disclosed by the other party to any third
party or used outside the scope of this Agreement, except that Horizon or
Warner-Lambert, as the case may be, may disclose such information to its
Affiliates or its employees who are under a similar obligation of secrecy in
furtherance of the purposes of this Agreement; provided, however, that the
aforesaid obligation of confidentiality assumed by Horizon and its Affiliates
and Warner-Lambert and its Service Providers hereunder will not apply to any
confidential information (collectively referred to as "Information" for purposes
of this Section 8.3) which (i) was or becomes available to Horizon or
Warner-Lambert, as the case may be, on a non-confidential basis from a source
that is not under an obligation (whether contractual, legal or fiduciary) to the
other party to keep such information or data confidential, (ii) was previously
known to the Receiving Party (defined below), as established by competent
evidence or (iii) was or becomes a part of the public domain through no fault of
the Disclosing Party (defined below). If the party receiving Information of the
other party (the "Receiving Party") is requested in any judicial or
administrative proceeding or by any Governmental Authority to disclose any
Information of the other party (the "Disclosing Party"), the Receiving Party
will give the Disclosing Party prompt notice of such request so that the
Disclosing Party may seek an appropriate protective order. The Receiving Party
will cooperate fully with the Disclosing Party in obtaining such an order. If in
the absence of a protective order the Receiving Party is nonetheless compelled
to disclose Information of the Disclosing Party, the Receiving Party may make
such disclosure without liability hereunder, provided that the Receiving Party
gives the Disclosing Party written notice of the Information to be disclosed as


                                       6
<PAGE>   118

far in advance of its disclosure as is practical and, upon the Disclosing
Party's request and at its expense, the Receiving Party will use reasonable
efforts to obtain reasonable assurances that confidential treatment will be
accorded to such Information. The obligations of confidentiality in this Section
8.3 will survive the expiration or earlier termination of this Agreement until
the confidential information disclosed hereunder is no longer "Information" as
defined herein.

         8.4      Third Party Beneficiaries. Each party intends that this
Agreement will not benefit or create any right or cause of action in or on
behalf of any Person other than Warner-Lambert, the Service Providers and
Horizon.

         8.5      Entire Agreement. This Agreement, including all Schedules
hereto (which Schedules are hereby incorporated into and made a part of this
Agreement), constitutes the entire agreement between the parties and supersedes
all previous communications, representations, agreements or understandings,
either oral or written, between the parties with respect to the subject matter
hereof and this Agreement may be amended, supplemented or modified only by a
written instrument duly executed by or on behalf of each party hereto.

         8.6      Authority. Horizon hereby authorizes Warner-Lambert and its
Affiliates and subcontractors to do all such things in the name or for the
account of Horizon as may be necessary or desirable for, or incidental to, the
performance of any of the Services in the ordinary course of business, including
the execution and delivery of any document.

         8.7      Contractual Relationship. Nothing contained in this Agreement
will be deemed to create any joint venture, partnership or principal-agent
relationship between Warner-Lambert and Horizon or any of their respective
Affiliates and neither of the parties will hold itself out in any manner which
would indicate any such relationship with the other.

         8.8      Assignment. This Agreement may not be assigned by either party
without the prior written consent of the other party. This Agreement will be
binding upon and, subject to the terms of the foregoing sentence, inure to the
benefit of the parties hereto, their respective successors, legal
representatives and assigns.

         8.9      Waiver. Any term or condition of this Agreement may be waived
at any time by the party that is entitled to the benefit thereof, but no such
waiver will be effective unless set forth in a written instrument duly executed
by or on behalf of the party waiving such term or condition. No waiver by any
party of any term or condition of this Agreement, in any one or more instances,
will be deemed to be or construed as a waiver of the same or any other term or
condition of this Agreement on any future occasion. All remedies, either under
this Agreement or by law or otherwise afforded, will be cumulative and not
alternative.

         8.10     Headings. The headings used in this Agreement have been
inserted for convenience of reference only and do not define or limit the
provisions hereof.

         8.11     Invalid Provisions. If any provision of this Agreement is held
to be illegal, invalid or unenforceable under any applicable present or future
law, and if the rights or obligations of any party hereto under this Agreement
will not be affected materially and adversely thereby, (a) such provision will
be fully severable, (b) this Agreement will be construed and enforced as if such
illegal, invalid or



                                       7
<PAGE>   119

unenforceable provision had never comprised a part hereof, (c) the remaining
provisions of this Agreement will remain in full force and effect and will not
be affected by the illegal, invalid or unenforceable provision or by its
severance herefrom and (d) in lieu of such illegal, invalid or unenforceable
provision, there will be added as a part of this Agreement by mutual agreement
of the parties, a legal, valid and enforceable provision as similar in terms to
such illegal, invalid or unenforceable provision as may be possible.

         8.12     Force Majeure. Except in the case of monetary obligations
hereunder, the occurrence of an event which materially interferes with the
ability of a party to perform its obligations or duties hereunder that is not
within the reasonable control of the party affected, not due to malfeasance and
that could not with the exercise of due diligence have been avoided ("Force
Majeure"), including, but not limited to, fire, accident, labor difficulty,
strike, riot, civil commotion, act of nature, delay or errors by shipping
companies or change in Law will not excuse such party from the performance of
its obligations or duties under this Agreement, but will merely suspend such
performance during the continuation of Force Majeure. The party prevented from
performing its obligations or duties because of Force Majeure will promptly
notify the other party hereto (the "Other Party") of the occurrence and
particulars of such Force Majeure and will provide the Other Party, from time to
time, with its best estimate of the duration of such Force Majeure and with
notice of the termination thereof. The party so affected will use its best
efforts to avoid or remove such causes of nonperformance. Upon termination of
Force Majeure, the performance of any suspended obligation or duty will promptly
recommence. Except as otherwise specifically provided herein, neither party will
be liable to the other party for any direct, indirect, consequential,
incidental, special, punitive or exemplary damages arising out of or relating to
the suspension or termination of any of its obligations or duties under this
Agreement by reason of the occurrence of Force Majeure. In the event that Force
Majeure has occurred and is continuing for a period of at least 2 months, the
Other Party will have the right to terminate this Agreement upon 30 days notice.

         8.13     Governing Law. This Agreement and the rights and obligations
of the parties hereunder will be governed by, and construed and interpreted in
accordance with, the laws of New York applicable to a contract executed and
performed in such state.

         8.14     Counterparts. This Agreement may be executed in counterparts,
each of which will be deemed an original, but both of which together will
constitute one and the same instrument.
