Attention: Susan Yoss, Treasurer/Senior Vice President

Ladies and Gentlemen:

                     You have advised The Chase Manhattan Bank ("Chase") and
Chase Securities Inc. ("CSI") that ISP Opco Holdings Inc., a Delaware
corporation (the "Borrower"), will require credit facilities in order to finance
the acquisition (the "Acquisition") by a newly formed direct or indirect
wholly-owned subsidiary of the Borrower ("Newco") of all of the outstanding
capital stock (the "Target Stock") of Dexter Corporation, a Connecticut
corporation (the "Target"). The Transaction will be effected through a tender
offer (the "Tender Offer") by Newco for the Target Stock followed by a merger
(the "Merger") of Newco with and into the Target (collectively, the "Two-Step
Acquisition"), for a price per share of $45. In that connection, you have
requested that CSI agree to structure, arrange and syndicate senior credit
facilities in an aggregate amount of up to $1,775,000,000 (the "Facilities") and
that Chase commit to provide the Facilities and to serve as administrative agent
for the Facilities. References herein to the "Transaction" shall include the
Two-Step Acquisition and the financings described herein and all transactions
related thereto.

                     CSI is pleased to advise you that it is willing to act as
advisor, lead arranger and book manager for the Facilities.

                     Furthermore, Chase is pleased to advise you of its
commitment to provide the entire amount of the Facilities upon the terms and
subject to the conditions set forth or referred to in this commitment letter
(the "Commitment Letter") and in the Summary of Terms and Conditions attached
hereto as Exhibit A (the "Term Sheet").

                     It is agreed that Chase will act as the exclusive
administrative agent, and that CSI will act as an advisor, lead arranger and
book manager, for the Facilities, and each will, in such capacities, perform the
duties and exercise the authority customarily performed and exercised by it in
such roles. You and we agree that no other agents, co-agents or arrangers will
be appointed, no other titles will be awarded and no compensation (other than
that expressly contemplated by the Term Sheet and the Fee Letter referred to



NY2:\924208\01\JT4G01!.DOC\54104.0016
<PAGE>
below) will be paid in connection with the Facilities without mutual
consultation and agreement among you, Chase and CSI.

                     We intend to syndicate the Facilities to a group of
financial institutions (together with Chase, the "Lenders") identified by us and
you. The timing, and any staging, of the syndication efforts would be determined
by CSI in consultation with you, and you agree actively to assist CSI in
completing a syndication satisfactory to it. Such assistance shall include (a)
your using commercially reasonable efforts to ensure that the syndication
efforts benefit materially from your existing lending relationships and, to the
extent possible, the existing lending relationships of the Target, (b) direct
contact between senior management and advisors of International Specialty
Products Inc. (the "Parent"), the Borrower and the proposed Lenders, (c)
assistance in the preparation of a Confidential Information Memorandum and other
marketing materials to be used in connection with the syndication and (d) the
hosting, with CSI, of one or more meetings of prospective Lenders.

                     In cooperation with you, CSI will manage the syndication,
including decisions to be made with you as to the selection of institutions to
be approached and when they will be approached, when their commitments will be
accepted, which institutions will participate, the allocations of the
commitments among the Lenders and the amount and distribution of fees among the
Lenders. To assist CSI in its syndication efforts, you agree promptly to prepare
and provide to CSI and Chase all information with respect to Parent, the
Borrower, the Target and the Transaction, including all financial information
and projections (the "Projections"), as we may reasonably request in connection
with the arrangement and syndication of the Facilities, the distribution of such
Projections in the arrangement and syndication of the Facilities being subject
to confidentiality provisions between you and the Target. You hereby represent
and covenant that (a) all information other than the Projections (the
"Information") that has been or will be made available to Chase or CSI by you or
any of your representatives is or will be, when furnished, complete and correct
in all material respects and does not or will not, when furnished, contain any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements contained therein not materially misleading in
light of the circumstances under which such statements are made and (b) the
Projections that have been or will be made available to Chase or CSI by you or
any of your representatives have been or will be prepared in good faith based
upon reasonable assumptions. You understand that in arranging and syndicating
the Facilities we may use and rely on the Information and Projections without
independent verification thereof.

                     As consideration for Chase's commitment hereunder and CSI's
agreement to perform the services described herein, you agree to pay to Chase
the nonrefundable fees set forth in Annex I to the Term Sheet and in the Fee
Letter dated the date hereof and delivered herewith (the "Fee Letter").

the services described herein are subject to (a) there not occurring or becoming
known to us any material adverse condition or material adverse change in or
affecting the business, operations or financial condition of the Borrower and
its subsidiaries, taken as a whole, or the Target and its subsidiaries, taken as
a whole, (b) our not becoming aware after the date hereof of any information or
other matter (including any matter relating to financial models and underlying
assumptions relating to the Projections) affecting Parent or the Target or their
respective subsidiaries or the Transaction that in our reasonable judgment is
inconsistent in a material and adverse manner with any such information or other
matter disclosed to us prior to the date hereof, and which is not known by any

<PAGE>

hereof, (c) there not having occurred a material disruption of or material
adverse change in financial, banking or capital market conditions that, in our
judgment, could materially impair the syndication of the Facilities, (d) our

shall be no competing offering, placement or arrangement of any material debt
securities or bank financing by or on behalf of the Parent or any of its
subsidiaries, (e) the negotiation, execution and delivery of definitive
documentation with respect to the Facilities reasonably satisfactory to Chase
and its counsel on or before October 31, 2000, (f) the Borrower having delivered
a notice (the "Closing Notice") to Chase and CSI at least 30 days prior to the
Tender Closing Date (as defined in the Term Sheet) to the effect that the Tender
Closing Date may occur on or after such 30 th day and (g) the other conditions
set forth or referred to in the Term Sheet. Any matters that are not covered by
the provisions hereof and of the Term Sheet are subject to the approval and
agreement of Chase, CSI and the Borrower.

                     You agree (a) to indemnify and hold harmless Chase, CSI,
their affiliates and their respective officers, directors, employees, advisors,
and agents (each, an "Indemnified Person") from and against any and all losses,
claims, damages and liabilities to which any such Indemnified Person may become
subject arising out of or in connection with this Commitment Letter, the
Facilities, the use of the proceeds thereof, the Transaction or any claim,
litigation, investigation or proceeding relating to any of the foregoing,
regardless of whether any Indemnified Person is a party thereto, and to
reimburse each Indemnified Person upon demand for any reasonable and documented
legal or other expenses incurred in connection with investigating or defending
any of the foregoing, provided that the foregoing indemnity will not, as to any
Indemnified Person, apply to losses, claims, damages, liabilities or related
expenses to the extent they are found by a final, non-appealable judgment of a
court to arise from the bad faith, willful misconduct or gross negligence of
such Indemnified Person, breach of law or agreement with the Parent or its
subsidiaries ("Non-Indemnifiable Losses"), and (b) to reimburse Chase, CSI and
their affiliates on demand for all reasonable and documented out-of-pocket
expenses (including due diligence expenses, syndication expenses, consultant's

disbursements of counsel) incurred in connection with the Facilities and any
related documentation (including this Commitment Letter, the Term Sheet, the Fee
Letter and the definitive financing documentation) or the administration,
amendment, modification or waiver thereof. No Indemnified Person shall be liable
for any damages arising from the use by unauthorized persons of Information or
other materials sent through electronic, telecommunications or other information
transmission systems that are intercepted by such persons or for any special,
indirect, consequential or punitive damages in connection with the Facilities,
except to the extent arising from a Non-Indemnifiable Loss.

                     You acknowledge that Chase and its affiliates (the term
"Chase" as used below in this paragraph being understood to include such
affiliates) may be providing debt financing, equity capital or other services
(including financial advisory services) to other companies in respect of which
you may have conflicting interests regarding the Transaction and otherwise.
Chase will not use confidential information obtained from you by virtue of the
Transaction or its other relationships with you in connection with the
performance by Chase of services for other companies, and Chase will not furnish
any such information to other companies. You also acknowledge that Chase has no
obligation to use in connection with the Transaction, or to furnish to you,
confidential information obtained from other companies.

without such consent shall be null and void), is intended to be solely for the
benefit of the parties hereto and is not intended to confer any benefits upon,
or create any rights in favor of, any person other than the parties hereto and
the Indemnified Persons.

                     This Commitment Letter may not be amended or waived except
by an instrument in writing signed by you, Chase and CSI. This Commitment Letter
may be executed in any number of counterparts, each of which shall be an
original, and all of which, when taken together, shall constitute one agreement.

understanding that neither this Commitment Letter, the Term Sheet or the Fee
Letter nor any of their terms or substance shall be disclosed, directly or
indirectly, to any other person except (a) to your officers directors,

consideration of this matter or (b) as may be compelled in a judicial or
administrative proceeding or as otherwise required by applicable law, rules and
regulations, including, without limitation, tender offer rules and regulations
(in which case you agree to inform us promptly thereof), provided, that the
foregoing restrictions shall cease to apply (except in respect of the Fee Letter
and its terms and substance) after this Commitment Letter has been accepted by
you.

                     The compensation, reimbursement, indemnification and
confidentiality provisions contained herein and in the Fee Letter shall remain

termination of this Commitment Letter or Chase's commitment hereunder.

entirety the Commitment Letter, dated March 23, 2000, between us and you, as
previously amended (other than the reimbursement, indemnification and
confidentiality provisions thereof).
