Ladies and Gentlemen:

         Attached to this letter is a form of Purchase Agreement, together with
the forms of Exhibits and Schedules referred to therein (collectively, the "Form
of Agreement"), among Pharmaceutical Resources, Inc. ("PRI"), as purchaser, and
ISP Hungary Holdings Ltd., ISP Investments Inc., ISP Chemicals Inc. and ISP
Technologies Inc. (collectively, "ISP"), as sellers, relating to the proposed
transactions contemplated therein. Capitalized terms used and not otherwise
defined herein are used herein as defined in the Form of Agreement.

         1. In consideration of PRI's covenants hereunder and for other good and
valuable consideration (the receipt and sufficiency of which are hereby
acknowledged by ISP), ISP hereby agrees that from the date of this letter until
the No-Shop Termination Date (as hereinafter defined), neither ISP nor any of
its officers or directors shall (a) solicit any Entity to make an Acquisition
Proposal (as hereinafter defined), (b) deliver confidential information relating
to the Business to any Entity for the purpose of knowingly facilitating such
Entity's making of an Acquisition Proposal or (c) engage in any negotiations
concerning an Acquisition Proposal. For purposes of this letter, (i)
"Acquisition Proposal" shall mean any proposal or offer from an Entity other
than PRI relating to an acquisition or purchase of the Shares, the Business or
any material part of the Assets, other than sales of inventory in the ordinary
course; and (ii) "No-Shop Termination Date" shall mean the earliest of (A) the
date of closing of any sale of equity securities by PRI after the date hereof,
(B) the eighth Business Day immediately following the date on which the
Registration Statement shall have been declared effective by the SEC and (C)
February 15, 2002 (the earliest of such dates being the "Execution Date");
provided, however, that if both PRI and ISP shall have duly executed and
delivered the Form of Agreement prior to the Cutoff Time (as hereinafter
defined), the No-Shop Termination Date shall mean the earlier of the Closing
Date and the Termination Date. PRI shall notify ISP in writing of the occurrence
of the Execution Date (the "Notice") promptly (and in any event within one
Business Day) following the occurrence of the Execution Date. Notwithstanding
the foregoing, however, it is agreed that neither any actions in connection with

any proposed acquisition (by merger or otherwise) of International Specialty
Products Inc., nor any public disclosure made in accordance with Section 4
below, shall constitute a violation of this Section 1.

         2. In consideration of ISP's covenants hereunder and for other good
and valuable consideration (the receipt and sufficiency of which are hereby
acknowledged by PRI), PRI hereby irrevocably and unconditionally agrees that, if
(a) ISP shall have delivered to PRI, by not later than 4:00 p.m. New York City
time on the first Business Day following ISP's receipt of the Notice (the "Start
Date"), a copy of the Form of Agreement (with no changes thereto other than any
wholly ministerial changes necessary to complete the Form of Agreement) duly
executed by ISP, and (b) ISP shall not have received from PRI, prior to 4:00
p.m. New York City time on the first Business Day following the Start Date (the
"Cutoff Time"), a copy of the Form of Agreement (with no changes thereto other
than any wholly ministerial changes necessary to complete the Form of Agreement)
duly executed and delivered by PRI, then PRI shall pay to ISP, by not later than
the second Business Day following the Start Date, in cash by wire transfer of
immediately available funds to an account to be designated by ISP, a fee and
expense reimbursement in an aggregate amount equal to $3,000,000 (Three Million
Dollars) (the "Fee"). The Fee, which PRI hereby acknowledges is reasonable,
shall not constitute a penalty and shall not be subject to offset or deduction
of any kind by PRI. The Fee shall be ISP's exclusive remedy against PRI in
respect of any failure of PRI to duly execute and deliver the Form of Agreement
prior to the Cutoff Time. If for any reason PRI fails to pay the Fee to ISP in
accordance with the terms hereof, (i) the Fee shall bear interest at the rate of
7% per annum from the Cutoff Time until paid in full to ISP, and (ii) PRI shall
in addition pay to ISP all costs and expenses (including reasonable legal fees
and expenses) of ISP in connection with any action taken to collect payment.

         3. Each of PRI and ISP shall make the appropriate filings (and pay
any required filing fees) under the HSR Act with respect to their respective
proposed participation in transactions contemplated by the Form of Agreement on
or as promptly as practicable following December 31, 2001. PRI shall not
voluntarily withdraw the Registration Statement or seek to delay SEC comments
thereto. The parties shall in good faith make any necessary revisions to the
Schedules on or prior to 12:00 a.m., New York City time on January 1, 2002.

         4. The contents, terms and existence of this letter and the Form of
Agreement are confidential and shall not be disclosed by PRI or ISP (or their
respective representatives, advisors or agents) without the other party's prior
written consent (except to the extent required by applicable law or applicable
stock exchange rule, or as may be necessary in connection with an action to
collect payment of the Fee or to enforce compliance with Section 1 hereof, but
in each case, only following delivery of reasonable prior notice of such
disclosure to the other party). Notwithstanding the foregoing, the parties shall
use their best efforts not to make any public announcement in respect of this
letter or the Form of Agreement until on or after January 14, 2002.

         5. Except as set forth in Section 2 above, PRI, on the one hand,
and ISP, on the other hand, shall each pay all of its own costs and expenses in
connection with this letter and the evaluation and negotiation of the
transactions contemplated by the Form of Agreement (including, without
limitation, commitment fees, bankers' and professionals' fees and HSR Act filing
fees), and any commitments or expenditures made by any party in connection
therewith are solely at the risk, and for the account, of such party.

         6. From and after the date hereof and until the Cutoff Time, ISP
and PRI shall each provide the other party reasonable access, during normal
business hours and following reasonable prior notice (and subject to applicable
restrictions imposed by law or under contract), to the properties, books and
records of PRI or of ISP relating to the Business, as the case may be, in each
case, to the extent reasonably requested for the purpose of enabling reasonable
further due diligence with respect to the transactions contemplated by the Form
of Agreement. It is understood and agreed, however, that nothing learned or
discovered during the course of such due diligence investigation shall change
the Form of Agreement for purposes of Section 2 of this letter unless (and only
to the extent that) such changes are expressly agreed to by both ISP and PRI.
All information disclosed to PRI in connection with such due diligence
investigation shall be subject to the provisions of the Confidentiality
Agreement previously executed by PRI and an Affiliate of ISP.

         7. PRI and ISP acknowledge and agree that this letter does not
obligate, and is not intended to represent a commitment, agreement or promise
of, any party to (a) execute the Form of Agreement or any other agreement or (b)
otherwise enter into, offer to enter into, or consummate, any transaction. A
binding commitment with respect to the transactions contemplated by the Form of
Agreement shall result only from the execution and delivery of the Form of
Agreement by the parties thereto. Notwithstanding the foregoing, the provisions
of Sections 1, 2, 3, 4 and 5 of this letter shall constitute legally binding and
enforceable agreements of PRI and ISP.

         8. This letter shall be construed and interpreted in accordance
with the laws of the State of New York. This letter may not be assigned or
delegated by any party without the prior written consent of the other parties,
and any purported assignment or delegation without such consent shall be null
and void.

                                PURCHASE AND SALE

                (v) the Sellers shall sell, assign, transfer and deliver to
Buyer, and Buyer shall purchase, acquire and accept from the Sellers, all of the

conveying or delivering to Buyer, any right, title or interest in or to the
Excluded Assets.

          (b)  Upon the terms and subject to the conditions of this Agreement,
at the Closing:

                (i) the Sellers shall deliver to Buyer (A) reasonable evidence
of transfer of record ownership of the Shares to Buyer, including any stock

Purchase Price and the Non-Competition Payment in accordance with Section 2.02
hereof by wire transfer of immediately available funds to such account or
accounts as the Sellers shall have specified to Buyer prior to the Closing Date
and (B) each of the Other Agreements executed by Buyer.

          2.02. PURCHASE PRICE; ALLOCATION.

          (a) The aggregate purchase price for the Shares and the Assets is
$107,820,000, subject to adjustment as provided below (the "Purchase Price"),
together with Buyer's assumption of the Assumed Liabilities. In addition, Buyer
shall pay $1,500,000 in consideration for the non-competition covenant set forth
in Section 5.04 hereof (the "Non-Competition Payment"). The Purchase Price shall
be allocated among the Shares and the Assets as set forth on Exhibit G hereto
and in accordance with paragraph (f) below. The Purchase Price (as it may be
adjusted pursuant to paragraph (c) below) together with the Non-Competition
Payment shall be paid by Buyer to the Sellers at the Closing by wire transfer of
immediately available funds to such account or accounts as shall have been
designated by the Sellers prior to the Closing Date. Each of the Sellers hereby
acknowledges and accepts the allocation of the cash Purchase Price and the
Non-Competition Payment among the Sellers as set forth on Exhibit G hereto
(subject to adjustment as set forth in paragraphs (c) and (e) below).


                                       13


          (b) The portion of the Purchase Price payable in consideration of the
Inventory (the "Inventory Purchase Price") is based, in part, on ISP
Technologies delivering to Buyer inventory of the U.S. Business with a value of
$4,312,000 (the "Target Amount"). The Inventory Purchase Price shall be adjusted
as follows to reflect the amount by which the Inventory Value (as hereinafter
defined) is greater or less than (as the case may be) the Target Amount. If the
Inventory Value is greater than the Target Amount, the Inventory Purchase Price
shall be increased by the amount of such excess, and if the Inventory Value is
less than the Target Amount, the Inventory Purchase Price shall be decreased by
the amount of such shortfall. The term "Inventory Value" shall mean the value of
the Inventory as of the Closing Date, determined in accordance with GAAP, using
the historical inventory valuation procedures of the Sellers, consistently
applied, and as such value may be reduced to reflect any breach of the
representations and warranties contained in Section 3.05(d) hereof. The Sellers
shall provide adequate prior written notice to Buyer as to when the Sellers
shall conduct a physical count of the Inventory in connection herewith, and
Buyer may participate in such Inventory count.

          (c) Not less than two Business Days prior to the Closing Date, ISP
Technologies shall deliver to Buyer a statement setting forth its good faith
estimate of the Inventory Value (the "Inventory Value Statement"). At the
Closing, the parties shall make an adjustment to the Inventory Purchase Price
(and, correspondingly, the Purchase Price), as follows, to reflect the amount by
which the Inventory Value as set forth on the Inventory Value Statement is
greater or less than (as the case may be) the Target Amount. If the Inventory
Value as set forth on the Inventory Value Statement is greater than the Target
Amount, the Inventory Purchase Price payable by Buyer at Closing shall be
increased by the amount of such excess, and if the Inventory Value as set forth
on the Inventory Value Statement is less than the Target Amount, the Inventory
Purchase Price payable by Buyer at Closing shall be decreased by the amount of
such shortfall.

          (d) Within 45 days after the Closing Date, Buyer shall notify ISP
Technologies in writing whether Buyer accepts the estimated Inventory Value set
forth in the Inventory Value Statement and, if so, no further adjustment to the
Inventory Purchase Price shall be required under this Section. If Buyer fails to
deliver written notice of its acceptance or objection to the estimated Inventory
Value set forth in the Inventory Value Statement within 45 days after the
Closing Date, Buyer shall for all purposes be deemed to have accepted such
Inventory Value and no further adjustment to the Inventory Purchase Price shall
be required under this Section. If, however, Buyer objects in good faith to the
determination of the Inventory Value set forth in the Inventory Value Statement,
Buyer shall deliver a written notice to ISP Technologies within such 45-day
period, which notice shall specify in good faith and in reasonable detail each
of Buyer's objections, and the parties shall each use reasonable best efforts
through authorized officers to resolve the objections in good faith. If no
resolution is reached within 15 days after the notice of objection is given,
then the issues that remain in dispute shall be promptly (and in any event
within 10 days) submitted to PriceWaterhouseCoopers (or, if such firm is unable
or unwilling to accept such engagement, another nationally-recognized
independent accounting firm with no pre-existing relationship with the Sellers
or Buyer as shall be mutually selected by ISP Technologies and Buyer) (the
"Arbitrator") for review and resolution. The fees and expenses of the Arbitrator


                                       14


shall be paid one-half by ISP Technologies and one-half by Buyer. Each party
shall submit to the Arbitrator such information as the Arbitrator reasonably
deems necessary to reach a conclusion as to the correct determination of
Inventory Value. The Arbitrator shall be directed to reach a written
determination within ten Business Days and to deliver such determination to
Buyer and ISP Technologies, whereupon such determination shall be final, binding
and conclusive upon the parties (absent manifest error).

          (e) If the Inventory Value as finally determined pursuant to paragraph
(d) above (the "Final Inventory Value") is equal to the estimate set forth in
the Inventory Value Statement, then no further adjustment to the Inventory
Purchase Price shall be required pursuant to this Section. If the Final
Inventory Value is less than the estimate set forth in the Inventory Value
Statement, then ISP Technologies shall promptly pay to Buyer the amount of such
shortfall plus interest thereon from the Closing Date until the date of payment
at the per annum rate of seven (7%) percent. If the Final Inventory Value is
greater than the estimate set forth in the Inventory Value Statement, then Buyer
shall promptly pay to ISP Technologies the amount of such excess plus interest
thereon from the Closing Date until the date of payment at the per annum rate of
seven (7%) percent . Each payment pursuant to this paragraph (e) shall be by
wire transfer of immediately available funds to such account as the party so
entitled to such payment shall designate in writing. The Inventory Purchase
Price adjustment provided for in this Section 2.02 shall be the exclusive remedy
of either party hereto in respect of the Inventory Value Statement or any
difference between the Inventory Value and the Target Amount.

          (f) Buyer and the Sellers shall allocate the Purchase Price and the
Non-Competition Payment as set forth on Exhibit G hereto and in accordance with
Section 1060 of the Code and the applicable rules and regulations thereunder.
Buyer and the Sellers shall report the transactions contemplated herein for all
purposes (including, without limitation, the filing of Internal Revenue Form
8594) in accordance with such allocation. In any proceeding related to the
determination of any Taxes, neither Buyer nor any of the Sellers shall contend
or represent that such allocation is not a correct allocation.

          2.03. ASSUMED AND RETAINED LIABILITIES; PRORATION. (a) As of, and at
all times subsequent to, the Closing, Buyer shall assume and be responsible for,
and shall pay, honor, perform and discharge as and when due, in accordance with
their respective terms, all of the Assumed Liabilities; provided, however, that
this Section 2.03(a) shall not limit any claims and defenses Buyer may have
against any party other than a Seller or an Affiliate of a Seller. It is
acknowledged and agreed that Buyer is not assuming from the Sellers, or in any
way responsible for, any of the Retained Liabilities.

          (b) All items listed below relating to the Sellers' operation of the
U.S. Business will be prorated as of the Closing Date (all such prorations being
made on the basis of the actual number of days of the year and month that shall
have elapsed as of the Closing Date), with the Sellers liable to the extent such
items relate to any time period ending on or prior to the Closing Date, and
Buyer liable to the extent such items relate to all periods subsequent thereto:
(i) real estate taxes, (ii) water, electricity, sewer, gas, telephone


                                       15


and other utility charges, (iii) fuel, if any, (iv) rents, (v) all fees under
service contracts for services rendered or to be rendered on or after the
Closing Date, and (vi) like items customarily prorated in transactions similar
to those contemplated by this Agreement. The Sellers shall be entitled to any
funds, bonds, letters of credit or deposits made by the Sellers with
municipalities, Governmental Entities and/or utility companies servicing or
having jurisdiction over the Real Property used in the U.S. Business, and if
same are not refundable to the Sellers without a replacement by Buyer, Buyer
shall either (x) deliver the required replacement funds and/or deposits to the
appropriate Governmental Entity prior to the Closing Date, or (y) pay to the
Sellers on the Closing Date the amount of such funds and/or deposits, in which
case the Sellers shall transfer all of the Sellers' right, title and interest to
such funds and deposits to Buyer. On or prior to the Closing Date, the parties
hereto will in good faith calculate an estimate of such proration adjustments
and a payment in the net amount thereof shall be paid by Buyer to the Sellers at
the Closing. To the extent that proration with respect to any of such items was
not definitively ascertainable or was erroneously calculated on the Closing
Date, such items shall be reprorated as promptly as practicable (but in any
event not later than 30 days after the Closing Date) and a cash settlement shall
be made between the parties promptly thereafter; provided, however, that if
final real estate tax bills of the tax year are not available on the Closing
Date, the real estate taxes apportionment shall be based upon preliminary tax
bills as if they were the final tax bills for the Real Property used in the U.S.
Business, with an adjustment to be made upon receipt of the final tax bills and
provided, further, that all cash payments made after the Closing Date shall be
accompanied by interest at the annual rate of seven (7%) percent . The parties
hereto shall promptly furnish to each other such documents and other records as
may be reasonably requested in order to confirm all proration calculations made
pursuant to this Section.

          2.04. NONASSIGNABLE RIGHTS. (a) Notwithstanding anything to the
contrary contained in this Agreement or in any Other Agreement, this Agreement
and the Other Agreements shall not operate to assign, and there shall not be
included in the Assets, any of the Assumed Contracts, Assumed Contracts Rights,
Intangible Property or Permits, or any claim, right or benefit arising
thereunder or resulting therefrom, if an attempted assignment thereof, without
the consent of any Entity, would constitute a breach, default or other
contravention thereof or a violation of law, unless and until all required
consents, approvals and waivers are obtained (it being understood and agreed
that the failure to obtain such consents, approvals and waivers shall not reduce
the Purchase Price nor shall it relieve the Sellers of any of their obligations
under this Agreement, including Section 2.04(b) hereof, or eliminate any of the
conditions of Buyer's obligations hereunder). To the extent that this Section
operates to exclude any of such Assumed Contracts, Assumed Contracts Rights,
Intangible Property, Permits, claims, rights or benefits, the definitions of
"Business", "Assets", "Assumed Contracts", "Assumed Contracts Rights" and
"Intangible Property" in this Agreement shall be modified to exclude such
assets.

          (b) The parties hereto shall use their respective commercially
reasonable best efforts promptly to obtain all necessary consents, waivers and
approvals of any third parties to the transfer of any of the Assumed Contracts


                                       16


or Licensed Intellectual Property or in respect of any of the Assets or any
claim, right or benefit thereunder, and shall reasonably cooperate with each
other in connection therewith; provided, however, that neither party shall be
obligated to spend any sum of money (other than reasonable legal fees and
administrative expenses incurred in connection therewith) or make any material
financial or other accommodation or concession to obtain such consents, waivers
and approvals. If such consents, approvals or waivers are not obtained by the
Closing, or if an attempted assignment thereof would be ineffective or would
adversely affect the claims, benefits or rights of the Sellers or Buyer
thereunder or Buyer would not in fact receive all such claims benefits or
rights, the parties will, to the extent legally permissible, cooperate in a
mutually agreeable arrangement under which Buyer, at no additional cost to it
(except as provided below), will obtain the claims, benefits or rights
thereunder in accordance with the intent of this Agreement, including
subcontracting, sub-licensing or sub-leasing to Buyer, or under which the
Sellers would enforce for the benefit of Buyer any and all rights of the Sellers
against a third party thereto; provided, however, that, subject to the
foregoing, if any such arrangement requires the Sellers to incur a cost or spend
any sum of money to perform and/or enforce for the benefit of Buyer any and all
such rights of the Sellers in connection therewith, Buyer shall promptly
reimburse all such costs and sums to the Sellers. In the event of a failure by
Buyer to make such reimbursement, the Sellers shall cease to be obligated under
this Section. The Sellers shall promptly pay to Buyer all monies received by the
Sellers in respect of any Assumed Contract or any of the other Assets or any
claim, right or benefit arising thereunder after the Closing Date. In the case
of any such subcontracting, sub-licensing, subleasing or similar arrangement,
Buyer shall indemnify, defend and hold the Sellers and their respective
Affiliates harmless from and against any and all Damages arising out of or
relating to Buyer's failure to perform its obligations pursuant to the terms of
such arrangement from and after the Closing Date, and in the event of a failure
of such indemnity, the Sellers shall cease to be obligated under this Section.

Such Seller or ISP Israel has good and valid title, free and clear of all Liens
except for Permitted Liens, to its leasehold interest in all equipment or other

Business on consignment. No such inventory is subject to recall. All items of
inventory reflected on the Interim Balance Sheet or acquired by ISP Technologies
or ISP Israel since the date of the Interim Balance Sheet consist of a quantity
and quality suitable and commercially usable and saleable in the ordinary course
of business for the purposes for which they are intended, in the ordinary course
of business, except for obsolete, slow-moving or defective items, all of which

Inventory has been reflected on such books and records and, as applicable, the
Interim Balance Sheet at the lower of cost or market value, the cost thereof

receivables. All accounts payable of ISP Israel, as reflected in the Interim
Balance Sheet or arising after the date thereof, are the result of bona fide
transactions in the ordinary course of business consistent with past practice.

          (b) POST-CLOSING ACCESS. Following the Closing, Buyer shall maintain
the contracts, agreements, documents and Books and Records of the Business for a
period of six years following the Closing Date. Following the Closing and until
the sixth anniversary of the Closing Date, Buyer shall, subject to Section 5.13
hereof, provide the Sellers and their employees, counsel, accountants and other
representatives reasonable access, during normal business hours and following
reasonable prior notice, to the contracts, agreements, documents and books and
records of Buyer and its Affiliates relating to the Business as conducted by the
Sellers and ISP Israel immediately prior to the Closing for any reasonable


                                       35


business purpose (including, without limitation, preparing tax returns,
administering benefit plans and defending or pursuing claims), and Buyer shall
cooperate and cause its Affiliates to cooperate and permit the Sellers and their
representatives to examine and copy, at the Sellers' expense, such contracts,
agreements, documents and books and records. In addition, Buyer agrees to
provide the reasonable assistance (including for purposes of prosecuting or
defending any claim) of those of its employees who may have knowledge of the
Business as conducted prior to the Closing.

          5.03. REASONABLE BEST EFFORTS; FURTHER ASSURANCES. Subject to the
terms and conditions of this Agreement and applicable law, each of the parties
shall act in good faith and use reasonable best efforts to take, or cause to be
taken, all actions and to do, or cause to be done, all things necessary, proper
or advisable to consummate the transactions contemplated by this Agreement as
soon as practicable. Without limiting the foregoing, the parties shall, and
shall cause their respective Affiliates to, (i) use reasonable best efforts to
obtain all consents (including, without limitation, the consent of Arie Gutman
to the assignment of the FineTech Agreement and the Indemnification Agreement),
approvals, waivers, licenses, Permits, authorizations, registrations,
qualifications or other permissions or actions by, and give all necessary
notices to, and make all filings with and applications and submissions to, any
Governmental Entity or other Entity required for the consummation of the
transactions contemplated by this Agreement as promptly as reasonably
practicable (including, without limitation, providing an undertaking to the
Office of the Chief Scientist, Ministry of Industry and Trade of the State of
Israel); (ii) provide all such information concerning such party and its
officers, directors, employees, partners and Affiliates as may be necessary or
reasonably requested in connection with the foregoing; (iii) take any and all
reasonable steps necessary to avoid the entry of, or have vacated or terminated,
any injunction, decree, order, or judgment that would restrain, prevent, or
delay the consummation of the transactions contemplated by this Agreement,
including but not limited to defending through litigation on the merits any
claim asserted in any court by any person; and (iv) take any and all reasonable
steps necessary to avoid or eliminate every impediment under any antitrust,
competition, or trade regulation law that is asserted by any Governmental Entity
with respect to the consummation of the transactions contemplated by this
Agreement so as to enable the consummation of the transactions contemplated by
this Agreement to occur as expeditiously as possible. Prior to making any
application to or filing with a Governmental Entity in connection with this
Agreement, each party shall provide the other party with drafts thereof and
afford the other party a reasonable opportunity to comment on such drafts. Buyer
and the Sellers shall each keep each other reasonably apprised of the status of
material matters relating to the completion of the transactions contemplated
hereby, including promptly furnishing the other with copies of notices or other
communications received by Buyer or the Sellers, as the case may be, or by any
of their respective Affiliates, from any third party and/or any Governmental
Entity with respect to the transactions contemplated by this Agreement.

          5.04. NON-COMPETITION. (a) In consideration of Buyer's payment at the
Closing of the Non-Competition Payment and other valuable consideration, ISP
Investments, ISP Technologies, ISP Chemicals and their respective parent
entities and subsidiaries and other Affiliates shall not, directly or
indirectly, for a period commencing on the Closing Date and ending on the fifth

                                       36


(5th) anniversary of the Closing Date, by ownership of securities or otherwise
(except as a holder of less than five (5%) percent of any class of equity
securities of any other entity, which class of securities shall have been
registered under Section 12 of the Securities Exchange Act of 1934), manage,
control, engage or actively participate in any business or activity that is
competitive with the Business; provided, however, that, notwithstanding the
foregoing, the Sellers and their respective parent entities and subsidiaries and
other Affiliates shall not be prohibited from:

                (i) engaging in any of such activities as expressly contemplated
under any of the Other Agreements or any other written agreement with Buyer or
any of its Affiliates;

                (ii) acquiring, owning and operating any business after the
Closing Date that includes operations the conduct of which would otherwise
violate this Section 5.04(a), if Buyer consents in writing thereto (such consent
not to be unreasonably withheld);

                (iii) acquiring, owning and operating any business (a "Target")
after the Closing Date that includes operations the conduct of which would
otherwise violate this Section 5.04(a) (the "Subject Operations"), if (A)(1)
such Subject Operations accounted (as of the end of, and for, the last fiscal
year of the Target immediately preceding the date of its acquisition by a Seller
or its Affiliate) for less than twenty five (25%) percent of the aggregate gross
revenues of the Target and (2) (unless Buyer consents in writing to such Seller
or its Affiliate not complying with this clause (2), such consent not to be
unreasonably withheld) such Seller or Affiliate uses its commercially reasonable
best efforts to dispose of such Subject Operations as soon as practicable and in
any event within 24 months following the consummation of such acquisition (and,
if such Seller or Affiliate does not dispose of such Subject Operations within
such 24-month period, it shall cause such Subject Operations to be permanently
shut down and discontinued (or otherwise cease to violate this Section 5.04(a))
prior to the 30-month anniversary of the closing of such acquisition); provided,
however, that the Sellers shall use commercially reasonable best efforts to
ensure that any director, officer or key employee of the Sellers that, through
his or her participation in the Business learned confidential information of the
Business that is material to the Business, shall not participate in the Subject
Operations until the earlier of (x) the fifth (5th) anniversary of the Closing
Date and (y) such time as he or she is no longer employed or retained by the
Sellers; and

                (iv) engaging in arbitrage investments and similar transactions
in connection with pending, publicly-announced business-combination
transactions.

          Notwithstanding the foregoing, the provisions of this Section 5.04(a)
shall not be applicable to the acquiring, acquired or successor Entity, or the
surviving Entity of any merger or consolidation, in the event that any Seller or
any of its respective parent entities or subsidiaries or other Affiliates is
acquired (or all or substantially all of its assets is acquired), directly or


                                       37


indirectly, after the Closing Date by any Entity whose activities or operations
include activities or operations described in the first paragraph of this
Section 5.04(a) (it being understood and agreed that, in the case of a merger or
other business combination, a Seller or its respective parent entities or
subsidiaries or other Affiliates shall be deemed "acquired" in the event that,
following such merger or other business combination, more than fifty (50%)
percent of the outstanding capital stock of the combined entity is owned by a
party or parties other than the shareholders of International Specialty Products
Inc. or any direct or indirect subsidiary of International Specialty Products
Inc., as applicable, immediately prior to such merger or other business
combination); provided, however, that the Sellers shall use commercially
reasonable best efforts to ensure that any director, officer or key employee of
the Sellers that, through his or her participation in the Business learned
confidential information of the Business that is material to the Business, shall
not participate in the operations of such entity that would otherwise violate
this Section 5.04(a) until the earlier of (x) the fifth (5th) anniversary of the
Closing Date and (y) such time as he or she is no longer employed or retained by
the Sellers or its successor Entity.

          (b) The Sellers acknowledge that a violation or threatened violation
of any of the provisions of Section 5.04(a) hereof may result in Buyer
sustaining irreparable harm, which result may not be fully redressed by the
payment of damages to Buyer, and, therefore, in addition to any other remedies
which Buyer may have under this Agreement or otherwise, Buyer shall be entitled
to apply to any court of competent jurisdiction, at law or in equity, for an
injunction enjoining or restraining any such violation, including rescission of
any violative transaction. If for any reason any court of competent jurisdiction
shall find any of the provisions of Section 5.04(a) hereof unreasonable in
duration or in geographic scope or otherwise, the prohibitions contained herein
shall be restricted to such time and geographic areas as such court determines
to be reasonable and which reflects the intention of the parties hereto to the
fullest extent permissible. Such restriction shall apply only with respect to
the operation of such provisions in the particular jurisdiction in which such
adjudication is made.

          5.05. PUBLIC ANNOUNCEMENTS. Except as reasonably determined to be
required by applicable law or the rules of any applicable stock exchange,
neither Buyer nor the Sellers shall, nor shall they permit any of their
respective Affiliates to, make any public announcement in respect of this
Agreement, the Other Agreements or the transactions contemplated hereby or
thereby without the prior written consent of the other parties hereto (which
consent shall not be unreasonably withheld or delayed).

          5.06. CERTAIN TAX MATTERS. (a) The Sellers shall be responsible for
and shall pay, when due, all Taxes relating to the U.S. Business up until and
including the Closing Date, and Buyer shall be responsible for and shall pay all
Taxes relating to the U.S. Business from and after the Closing Date.

          (b) The Sellers shall prepare and file, or cause to be prepared and
filed, all Tax Returns of ISP Israel for all Tax periods ending on or prior to
the Closing Date, and pay or cause to be paid, when due, all Taxes owing under
such Tax Returns (except to the extent such Taxes were reserved for on the
Interim Balance Sheet or accrued by ISP Israel in the ordinary course of
business since the date of the Interim Balance Sheet).




          (c) Notwithstanding anything to the contrary contained in this
Agreement or provided by applicable law, all sales or real property, stock or
other transfer or similar taxes arising directly from the consummation of the
transactions contemplated hereby shall be paid by the Sellers. The Sellers shall
prepare and file all Tax Returns in connection with all such sales and transfer
taxes. Buyer shall provide the Sellers, upon their request, not less than two
(2) Business Days prior to the Closing Date, in properly completed form, all
exemption certificates with respect to such sales and transfer taxes that may be
executed by Buyer under applicable law, including a multi-jurisdictional sales
and use tax resale certificate with respect to Buyer's purchase of the
Inventory.

          (d) From and after the Closing Date, the Sellers and Buyer shall
cooperate with each other and provide each other with such assistance (including
testimony) as reasonably may be requested by either of them in connection with
the preparation of any Tax Return or any audit or other examination by any
taxing authority, any judicial or administrative proceedings relating to any
liability for Taxes under this Agreement, or any claims for refunds. The party
requesting assistance hereunder shall reimburse the party providing assistance
for all reasonable third-party out-of-pocket expenses incurred in providing such
assistance.

          5.07. OTHER AGREEMENTS. At the Closing, Buyer and each of the Sellers,
to the extent that it is a party thereto, shall enter into, execute and deliver
each of the Other Agreements.

          5.08. DISCHARGE OF RETAINED LIABILITIES. From and after the Closing,
the Sellers shall pay, honor, perform or discharge the Retained Liabilities in
accordance with their respective terms; provided, however, that nothing in this
Section 5.08 shall limit any claims or defenses any Seller may have against any
party other than Buyer or its Affiliates.

          5.09. EMPLOYEES. (a) As soon as practicable after the date hereof and
prior to the Closing, Buyer shall provide a written offer of employment (subject
to the Closing) to each employee of the U.S. Business identified on Schedule
5.09(a) hereto, except for those employees identified by Buyer thereon
("Excepted Employees"), even if any such employee is on long-term disability,
approved vacation, short-term sick days, approved leave of absence, short-term
disability leave or otherwise not actively working. Buyer acknowledges and
agrees that its identification of the Excepted Employees to whom it declines to
offer employment will be determined in its sole discretion and that the Sellers
had no part in such determination. Buyer agrees to offer each employee of the
U.S. Business (other than the Excepted Employees) the same or a substantially
similar position as he or she held with the Sellers immediately prior to the
Closing Date and salary or hourly wages, as applicable, in amounts no less
favorable than the salary or hourly wages, as applicable, paid to such employees
immediately prior to the Closing Date at the same geographic location of
employment. Buyer shall, as of the Closing, employ such employees of the U.S.
Business who accept Buyer's offer of employment (the "Affected Employees") at
their respective current geographic locations of employment. With respect to
Affected Employees not actively working as of the Closing Date, Buyer shall


                                       39


employ them upon return to active employment. Nothing in this Agreement shall be
construed to limit Buyer's ability to, at any time after the Closing Date,
terminate, relocate, re-assign or otherwise change the terms and conditions of
employment of any Affected Employee and/or employee of ISP Israel ("Israel
Employees"). Buyer shall give the Affected Employees credit for all service with
the Sellers or any of their Affiliates (and service credited by a Seller or any
of its Affiliates), to the same extent as such service was credited for such
purpose by a Seller or any of its Affiliates, under (i) all employee benefit
plans (as such term is defined under Section 3(3) of ERISA), programs and
policies of Buyer in which they become participants for purposes of eligibility
and vesting (but not for purposes of benefit accrual other than as provided
below), (ii) all severance plans applicable to Affected Employees for purposes
of calculating the amount of each Affected Employee's severance benefits and
(iii) any other benefits that the Affected Employees shall be entitled to under
applicable laws, rules or regulations. To the extent permissible under the terms
thereof and applicable law, Buyer shall (A) waive all limitations as to
preexisting condition exclusions and waiting periods with respect to
participation and coverage requirements applicable to the Affected Employees
under any welfare benefit plans of Buyer that such employees are eligible to
participate in on the Closing Date, other than limitations or waiting periods
that are already in effect with respect to such employees and that have not been
satisfied as of the Closing Date under any welfare benefit plan maintained for
the Affected Employees immediately prior to the Closing Date, and (B) provide
each Affected Employee with credit for any co-payments and deductibles paid
(with respect to the plan year in which the Closing occurs) prior to the Closing
Date in satisfying any applicable deductible or out-of-pocket requirements under
any welfare plans that such employees are eligible to participate on the Closing
Date.

          (b) Buyer and its Affiliates shall not adopt or assume any liability
or obligation or liability (direct or indirect) with respect to any Seller
Benefit Plan other than an Israel Benefit Plan. Effective as of the Closing,
Buyer shall cause each Affected Employee to be eligible to participate in the
employee benefit plans, programs and arrangements maintained by Buyer and
identified on Schedule 5.09(b) hereto, in accordance with the terms and
conditions of such plans, programs, plans and arrangements, as applicable to
Buyer's employees generally and as may be amended from time to time. The parties
hereto acknowledge and agree that as of the Closing, the Affected Employees will
cease accruing benefits under and shall cease participation in all of the Seller
Benefit Plans (other than the Israel Benefit Plans).

          (c) The Sellers shall retain and be solely responsible for all
liabilities and obligations arising out of or pertaining to the employment or
termination of employment of the Affected Employees and the employees of ISP
Israel, to the extent that such liabilities or obligations are based on or
relate to events, omissions or actions of the Sellers or ISP Israel occurring or
agreements (including severance, termination, retention or change of control
agreements or arrangements that result in any payment, compensation or benefit,
including, without limitation, cash or equity-related, owed to such individuals)
entered into or adopted by the Sellers or ISP Israel on or prior to the Closing
Date or as a result of or in connection with the transactions contemplated
hereby. All such liabilities and obligations shall be Retained Liabilities. The
Sellers shall further retain and be solely responsible for all liabilities and


                                       40


obligations arising out of or pertaining to the employment or termination of
employment of all individuals employed by the Sellers in connection with the
Business who are not offered positions of employment with Buyer or who do not
accept Buyer's offer of employment, and all such liabilities and obligations
shall be Retained Liabilities. The Sellers shall also honor, pay and be solely
responsible for payment of all claims for any benefits accruing, or with respect
to occurrences commencing, on or before the Closing under any Seller Benefit
Plan (other than an Israel Benefit Plan), including, but not limited to, (A)
hospital benefits for any confinements that commenced on or before the Closing,
including any covered charges of health care professionals relating to such
confinements; (B) short-term and long-term disability benefits, if any, for
disabilities that commenced on or before the Closing for the period that each of
such affected individuals remain disabled; (C) life and survivor income
benefits, if any, for deaths that occur on or prior to the Closing; (D) all
benefits that are being, or that may be, paid to, or with respect to, any of
such employees who are on short or long-term disability, or medical, personal or
other leaves of absence as of the Closing or who go on short or long-term
disability, or medical, personal or other leaves of absence after the Closing as
a result of any injury, illness or other factor occurring on or prior to the
Closing pursuant to the terms of such plans as in effect immediately prior to
the Closing (including any subsequent benefit increases); (E) benefits under any
"spending account" or similar arrangement under any "cafeteria plan" (as defined
in Section 125 of the Code) with respect to salary reduction elections made
prior to the Closing; (F) workers' compensation liabilities; (G) accrued, unused
vacation time and sick leave benefits; and (H) benefits under all other Seller
Benefit Plans that accrue on or before the Closing.

          (d) On and after the Closing, Buyer shall be responsible for and
assume any and all liability for all (i) notices, payments and benefits
(including, without limitation, severance payments and payments pursuant to the
Worker Adjustment and Retraining Notification Act of 1988, and any similar state
or local "plant closing" or "mass layoff" statute) due to any Affected Employees
terminated by Buyer or any of its Affiliates on or after the Closing, including,
without limitation, (A) pursuant to any applicable Employment Agreements, Buyer
benefit plans or corporate policies or programs pertaining to payroll, severance
pay, accrued vacation, fringe benefits and similar obligations or (B) as a
result of the termination by Buyer or any of its Affiliates of any Affected
Employee's employment after the Closing, and (ii) notices, payments, fines or
assessments due to any Governmental Entity, pursuant to any applicable foreign,
United States Federal, state or local law, common law, statute, rule or
regulation with respect to the employment, discharge or layoff of any such
Affected Employees by Buyer or its Affiliates on or after the Closing; in each
case under clauses (i) and (ii), other than where termination results from a
termination by a Seller or its Affiliates.

          (e) On and after the Closing Date, Buyer (or any plan maintained by
Buyer or its Affiliates) shall, without cost to the Sellers or any of their
respective Affiliates, offer continued health and medical coverage as required
under Section 4980B of the Code, Part 6 of Title I of ERISA or any other
applicable Federal, state or local law or ordinance to all Affected Employees
(and their spouses, dependents and beneficiaries) with respect to whom a


                                       41


"qualifying event" (as such term is defined under Sections 4980B(f)(3) of the
Code or 603 of ERISA) or other triggering event described under applicable
Federal, state or local laws or ordinances occurs with respect to any plan
maintained by Buyer after the Closing Date.

          (f) Buyer shall bear, and shall indemnify, defend and hold harmless
the Sellers and their Affiliates and their respective directors, officers,
employees, representatives and agents from, against and in respect of any and
all losses, damages, expenses (including reasonable attorneys' fees), judgments
and other liabilities arising from or relating to the Affected Employees or
Israel Employees with respect to events arising after the Closing, including,
but not limited to (i) the termination by Buyer or its Affiliates of any
Affected Employee or any Israel Employee after the Closing Date, (ii) the
modification of the terms of employment of any Affected Employee or Israel
Employee, or any of the benefits received by any Affected Employee or Israel
Employee, after the Closing, (iii) any claim made by any Affected Employee or
Israel Employee for severance payments arising after the Closing or (iv) any
suit or claim (including, without limitation, by any administrative or
governmental agency) brought against any party indemnified under this Section
5.09(f) alleging the violation of any applicable employment or labor law by
Buyer or any of its Affiliates which occurred on or after the Closing; provided,
however, that nothing in this Section 5.09(f) shall be construed to cause any
person or entity other than the Sellers to be responsible for the obligations
set forth in Section 5.09(c) hereof.

          (g) As soon as practicable after the Closing and effective as of the
Closing, the Affected Employees who were covered by the savings plan entitled
"Capital Accumulation Plan for Employees of GAFMC and ISP", a copy of which was
previously delivered to Buyer (the "Seller Savings Plan") prior to the Closing
Date shall be eligible to participate in Buyer's 401(k) Plan, in accordance with
its terms and conditions (the "Buyer Savings Plan"). Buyer shall cause the Buyer
Savings Plan to count for purposes of eligibility and vesting all service of the
Affected Employees that was counted for such purposes under the Seller Savings
Plan. The Sellers shall promptly provide Buyer with a copy of the most recently
issued determination letter from the U.S. Internal Revenue Service regarding the
Seller Savings Plan.

          (h) Representatives of Buyer shall be entitled to hold an initial
meeting with the employees of the Business in each jurisdiction upon reasonable
notice to the Sellers to explain and answer questions about the conditions,
policies and benefits of employment under Buyer. Thereafter, until the Closing,
the Sellers shall reasonably cooperate with Buyer in communicating to the
employees of the Business any additional information concerning employment under
Buyer that such employees may seek, or that Buyer may desire to provide, and
during normal working hours shall allow such additional meetings by
representatives of Buyer with such employees as Buyer may reasonably request.
The Sellers shall be entitled to have one or more representatives attend all
such meetings.

          (i) To the extent that the Closing does not coincide with the end of
any of the Sellers' payroll periods, the Sellers shall be responsible to pay all
payroll and related taxes and benefit payments and contributions for all


                                       42


Affected Employees for such portion of such payroll period that shall occur
prior to the Closing, and Buyer shall be responsible to pay all payroll and
related taxes and any benefit payments and contributions for all Affected
Employees hired by Buyer for such portion of such payroll period that shall
occur following the Closing.

          (j) The Sellers agree, if requested by Buyer, to cooperate on a
reasonable basis, to the extent permitted by applicable law, with Buyer's
application to designate Buyer (or its designee) as successor employer to the
Business for purposes of unemployment insurance, payroll tax or contribution
ratings and payroll credits pursuant to state and Federal law and/or worker's
compensation contribution premium ratings pursuant to applicable state law. The
Sellers shall, to the extent Buyer provided them with a reasonable opportunity
to comply, supply Buyer (or its designee) in a timely fashion with any payroll
or other account data as may be necessary or appropriate to make application for
the transfer of the Sellers' ratings, payroll credits and premium ratings as an
employer subject to unemployment compensation laws and/or workers' compensation
laws with any Governmental Entity. Buyer agrees, if requested by the Sellers, to
utilize the alternate procedure for furnishing Forms W-2 set forth in Rev. Proc.
96-30.

          (k) As of the Closing, Buyer undertakes to cause ISP Israel to
continue the employment of the ISP Israel employees under the same terms as
before the Closing.

          5.10. USE OF ISP NAME; ETC. Promptly, and in any event within 10 days,
following the Closing Date, Buyer shall deliver to the Sellers evidence
confirming that the corporate name of ISP Israel has been changed to a name that
does not include the term "International Specialty Products" or "ISP" or any
derivation thereof. Buyer shall not, and shall not permit any of its Affiliates
(including, from and after the Closing Date, ISP Israel) to, use the names
"International Specialty Products" or "ISP" or the International Specialty
Products or ISP trademarks or logo, or any derivation, similar variation or
simulation thereof, in any business, activity, promotional materials, or other
manner, or in connection with any product or service, without the Sellers'
specific prior written consent. Without limiting the foregoing, promptly, and in
any event within 10 days following the Closing Date, Buyer shall remove from
each Real Property all signage containing the names "International Specialty
Products" or "ISP", or any ISP trademarks or logos, or any derivation, variation
or simulation thereof. Notwithstanding the foregoing, Buyer may, for a period of
up to 120 days following the Closing Date, sell and/or distribute any products
containing the names or marks "International Specialty Products" or "ISP";
provided, that Buyer will use commercially reasonable best efforts during such
period to cover the name "ISP" or "International Specialty Products" and any
related marks or logos through use of additional labels, stickers or otherwise
to indicate that Buyer, and not "ISP" or "International Specialty Products", is
the seller and/or distributor of any of such products.

          5.11. TITLE INSURANCE. The Sellers shall obtain good and valid,
irrevocable ALTA title insurance commitments (collectively, the "Title
Commitments"), in final form, from Chicago Title Insurance Company (the "Title
Company"), irrevocably committing the Title Company (subject only to the
satisfaction of any reasonable requirements contained in the Title Commitments)


                                       43


to issuing ALTA form title insurance policies (collectively, the "Title
Policies") insuring, in the amounts that Buyer reasonably requests prior to
Closing good, valid, marketable, indefeasible fee simple title to each parcel of
the Owned Real Property, in Buyer, subject to no Liens or other rights of
occupancy or use for all or any portion thereof, options, security interests,
covenants, conditions, restrictions, rights of way, easements, encroachments or
other matters affecting title or other exceptions to title other than: (i) ALTA
standard printed exceptions (other than mechanic's and materialmen's liens and
rights of possession except if same constitute Permitted Closing Liens) and (ii)
the Permitted Closing Liens. The Title Commitments shall be effective as of a
date occurring not earlier than the date of this Agreement and the effective
date thereof shall be brought down to the Closing Date. The Title Policies shall
include such standard endorsements thereto as may reasonably be requested by
Buyer, including, without limitation, access and zoning endorsements, in form
and substance acceptable to Buyer. On or prior to the Closing Date, the Sellers
shall execute and deliver, or cause to be executed and delivered, to the Title
Company any reasonable title affidavits reasonably requested by the Title
Company in connection with the issuance of the Title Commitments or the Title
Policies. The Sellers shall pay all premiums and other charges for such Title
Policies and Title Commitments, including the cost of any endorsements thereto.

          5.12. SURVEY. Buyer acknowledges that the Sellers have delivered to
Buyer a copy of that certain survey of the Owned Real Property prepared by DLZ
Ohio, Inc. and certified as of November 13, 2001 (the "Survey"). The Sellers
shall reasonably cooperate, at no expense to the Sellers, in causing the Survey
to be certified to Buyer, the Title Company and Buyer's lender(s) and shall
comply, at no expense to the Sellers, with any requirements imposed by the Title
Company as a condition to the removal of any survey exception from the general
(but not specific) exemptions to the Title Policies.

          5.13. CONFIDENTIALITY. For a period of five (5) years from and after
the Closing Date, each of the Sellers shall treat and hold as confidential all
confidential information relating exclusively to the operations or affairs of
the Business. Without limiting the foregoing, each of the Sellers shall not, and
shall cause each of its Affiliates not to, disclose any such confidential
information to any Entity (except, as consistent with the Sellers past
practices, to such Entity's employees, auditors, counsel, other professional
advisors or its Affiliates) or make use of or exploit any such confidential
information for its own purposes or for the benefit of any other Entity. In the
event that any Seller or its Affiliate is required (by oral or written request
for information or documents in any legal proceeding, interrogatory, subpoena,
civil investigative demand or similar process or by applicable law) to disclose
any such confidential information, then such Seller will promptly notify Buyer
of the requirement so that Buyer, at its expense, may seek an appropriate
protective order or waive compliance with this Section 5.13. If, in the absence
of a protective order or receipt of a waiver hereunder, the Sellers or any of
their respective Affiliates are, on the advice of counsel, compelled to disclose
such confidential information, the Sellers or such Affiliate may so disclose the
confidential information; provided, however, that the Sellers or the Affiliate,
as the case may be, will use all reasonable efforts to obtain reliable assurance
that confidential treatment will be afforded to such confidential information.
The provisions of this Section 5.13 will not be deemed to prohibit the


                                       44


disclosure by the Sellers of confidential information relating to the operations
or affairs of the Business and any other operations or affairs relating to the
Business with Buyer's consent or to the extent reasonably and directly required
(i) to prepare or complete any required Tax Returns or financial statements,
(ii) in connection with reports, statements, testimony audits or other
proceedings before, by or on behalf of a Governmental Entity, (iii) in
connection with any insurance or benefits claims, (iv) to comply with any
applicable laws, (v) to prosecute or defend any suit, claim (including in
connection with this Agreement) or other litigation, or in response to any
summons or subpoena, or (vi) to provide services to Buyer in accordance with the

          5.14. NON-INTERFERENCE. From the Closing Date until the third (3rd)
anniversary of the Closing Date, (i) each of the Sellers shall not, without
Buyer's consent, hire or recruit any employee of Buyer (including any Affected
Employee) or solicit or induce, or attempt to solicit or induce, any employee of
Buyer to terminate his/her employment with, or otherwise cease his/her
relationship with Buyer (including any Affected Employee), and (ii) Buyer shall

employment with, or otherwise cease his/her relationship with, such Seller;
provided, that neither any Seller nor Buyer shall be prohibited from hiring any
employee of any Seller or Buyer, as applicable, who initiates contact with a
Seller or Buyer, as the case may be, in response to a general published
solicitation.

          5.15. RIGHT OF ENFORCEMENT AND SETTLEMENT. (a) Subject to Article IX
hereof, from and after the Closing, Buyer shall have complete control over the
payment, settlement or other disposition of all Assumed Liabilities and the

manner reasonably requested by Buyer involving the defense, settlement or other
disposition of any Assumed Liabilities.

          (b) Subject to Article IX hereof, from and after the Closing, the

that are reasonably requested by Buyer to be included in a Form 8-K to be filed
pursuant to the Securities and Exchange Act of 1934 in connection with the
transactions contemplated hereby and the Sellers shall, upon request from Buyer,
provide Buyer with unaudited financial statements of the Business for the
12-month period ending December 31, 2001 as soon as reasonably practicable, it
being understood that the Sellers make no representations or warranties
hereunder in respect of such audit or financial statements, except to the extent
set forth in Section 3.03 hereof. In addition, the Sellers shall reasonably make
their personnel and accountants available, at Buyer's cost, in connection with
the preparation of such audit and financial statements.

          5.17. FIRPTA CERTIFICATE. At or prior to Closing, ISP Chemicals shall

          5.18 SUPPLEMENTAL DISCLOSURE. (a) The Sellers agree that, with respect
to the representations and warranties made by them in this Agreement, they will
have a continuing obligation up to the Closing to promptly supplement and/or
amend the Schedules to this Agreement, with respect to any matter hereafter
arising or discovered of which the Sellers become aware prior to the Closing
that, if existing or known as of the date of this Agreement, would have been
required to be set forth or described in the Schedules to this Agreement. No
such supplemented or amended Schedule shall be deemed to cure any breach of
representation or warranty for any purpose or limit or otherwise affect the
remedies available hereunder if the Closing does not occur as a result of such
breach. If, however, the Closing occurs, any such supplement or amendment of any
Schedule shall be effective to cure and correct for all purposes any breach of
any representation or warranty that would have existed by reason of the
party(ies) not having made such supplement or amendment.

          (b) In addition, the Sellers shall promptly supplement and/or amend
the Schedules to this Agreement to reflect any event or condition that occurs
after the date hereof until the Closing of which the Sellers become aware prior
to Closing that, had it existed on the date hereof, would have caused any of the
representations and warranties of the Sellers contained herein to be incorrect
in any material respect (or would have caused representations and warranties
that are subject to materiality standards or qualifications to be incorrect in
any respect and without giving effect to any knowledge qualifier). The addition
of any such information to the Schedules to this Agreement shall not affect the
condition to Buyer's obligation set forth in Section 6.01 hereof; provided,
however, that the disclosure of such information shall not alter or diminish the
indemnification obligations of the Sellers set forth in Section 9.02(a)(i)
hereof and the Closing shall not cure or correct any such deemed breach of
representation or warranty referred to in the first sentence of this Section
5.18(b).

          (c) Prior to the Closing, Buyer shall disclose promptly to the Sellers
any discovery by it of a breach of any representation or warranty made by the
Sellers herein.

          5.19 ADDITIONAL COVENANTS OF BUYER. Buyer shall, subject to the last
proviso of Section 6.04 hereof, use its best efforts to (a) cause the

limitation, by filing such amendments and supplements thereto, and responding to
comments of, and providing such additional information as requested by, the SEC
in connection therewith), (b) consummate the Equity Financing and (c) cause all
conditions within its control to the consummation of the Credit Facility to be
satisfied (and remain satisfied through the Closing Date), in each case under
clauses (a), (b) and (c), as promptly as practicable following the date of this
Agreement. Without limiting the foregoing, Buyer shall use its best efforts to
avoid the entry of any suspension, stop order or similar proceeding in respect
of the Registration Statement (or, if one is entered, to have it rescinded as
promptly as practicable). Buyer shall (i) keep the Sellers apprised on a timely
basis of the status of the Registration Statement, the Equity Financing and the
Credit Facility, and promptly notify Sellers of any developments relating
thereto (including, without limitation, Buyer being aware of any event or
circumstance that could cause any of the conditions thereunder (or hereunder
relating thereto) not to be satisfied), and (ii) deliver to the Sellers true and
complete copies of any amendment to or modification of any of the documents

written request Buyer shall, at no charge to the Sellers and in a commercially
reasonable manner, store the inventory described on Schedule 1.01(y) hereto (the
"Excluded Inventory") at the Facility and maintain and protect the Excluded
Inventory in substantially the same manner as Buyer maintains and protects
similar items of tangible property located at the Facility. From time to time
following the Closing, Buyer shall ship (at the Sellers' expense) items of the
Excluded Inventory in such manner and to such locations as the Sellers may
reasonably direct in writing. Buyer shall use commercially reasonably efforts to
not permit any Lien arising by or through Buyer to attach or encumber the
Excluded Inventory. The Sellers shall bear any risk of loss in respect of the
Excluded Inventory.

          5.21 CUSTOMER CONFIDENTIALITY. With respect to any Assumed Contract
that any of the Sellers have entered into with any of their respective customers
and that requires the consent of such customer to the assignment of such
Contract, Buyer shall ensure that any confidential information provided by such
customer to the Sellers or Buyer, as the case may be, shall continue to be held
confidentially such that no Buyer Entities or Buyer personnel involved in the
research, development, manufacture and/or sale of any generic drugs shall have
access to such confidential information.

          The obligation of Buyer under this Agreement to consummate the Closing
is subject to the satisfaction of each of the following conditions at or prior

                                       47


to the Closing Date, any one or more of which may be waived in writing by Buyer
in its sole discretion to the extent permitted by applicable law:

          6.01. REPRESENTATIONS AND WARRANTIES; NO MATERIAL ADVERSE EFFECT. The
representations and warranties of the Sellers contained in this Agreement shall
have been true and correct in all material respects as of the date of this
Agreement (except for such representations and warranties which (a) are made
expressly as of an earlier specified date or period, which shall have been true
and correct in all material respects as of such specified date or period and (b)
are subject to materiality standards or qualifications, which representations
and warranties shall have been true and correct in all respects as of the date
of this Agreement). Between December 28, 2001 and the Closing Date, no event
shall have occurred that has had a Material Adverse Effect. Buyer shall have
received a certificate dated as of the Closing Date executed by an executive
officer of each of the Sellers certifying as to the foregoing.

          6.02. COMPLIANCE WITH COVENANTS. The Sellers shall have performed in
all material respects all covenants and agreements required to be performed by
them under this Agreement at or prior to the Closing Date, and Buyer shall have

injunction prohibiting or materially restricting the consummation of the
transactions contemplated hereby shall have been issued by any Governmental
Entity and be in force.

          6.04. NO BUYER MATERIAL ADVERSE CHANGE. Between December 28, 2001 and
the earlier of (a) such time as Buyer shall have consummated an Equity Financing
and (b) 5:00 p.m., New York City time, on the eighth (8th) Business Day
immediately following the date on which the Registration Statement shall have
been declared effective by the SEC (the earlier of the times described in
clauses (a) and (b) being the "Special Condition Fall-Away Time"), no Buyer MAC
(as defined below) shall have occurred. Notwithstanding the foregoing, it is
understood and agreed that the condition set forth in this Section 6.04 shall be
deemed satisfied as of (and, accordingly, such condition shall expire and be of
no force or effect from and after) the Special Condition Fall-Away Time, and as
of and from and after the Special Condition Fall-Away Time the only conditions
to Buyer's obligations shall be those expressly set forth in Sections 6.01,

hereby) of Buyer and its subsidiaries taken as a whole that has had or would
reasonably be expected to have a material adverse effect on the ability of Buyer

considered in determining whether a Buyer MAC shall have occurred: (1) any fact,
event, development, circumstance, condition or state of affairs of which Buyer
had knowledge as of the date of this Agreement, (2) changes (or the effects of
changes), in and of themselves, in the trading or market prices of Buyer's
securities or (3) changes, in and of themselves, attributable to this Agreement,
the transactions contemplated thereby or the announcement or other disclosure
thereof; provided, further, that if the SEC were to issue comments or impose
requirements in respect of the Registration Statement which, if addressed or
implemented by Buyer, would require a significant restatement or amendment of
Buyer's financial statements and such restatement or amendment could reasonably
be expected to have a material adverse effect on the ability of Buyer to
consummate the Equity Financing, such an occurrence shall be deemed a Buyer MAC.

          6.05 REGISTRATION STATEMENT. The Registration Statement shall have
been declared effective by the SEC and eight (8) Business Days shall have
elapsed since the date of such declaration of effectiveness without any order of
suspension thereof being issued by the SEC. Notwithstanding the foregoing, it is
understood and agreed that the condition set forth in this Section 6.05 shall be
deemed satisfied as of (and, accordingly, such condition shall expire and be of
no force or effect from and after) the Special Condition Fall-Away Time, and as
of and from and after the Special Condition Fall-Away Time the only conditions
to Buyer's obligations shall be those expressly set forth in Sections 6.01,
6.02, 6.03, 6.06, 6.07 and 6.08 hereof.

adverse impact on the ability to syndicate the Bridge Loans or to sell or place
the Permanent Financing.

          6.08 CUSTOMER CONSENTS. The Sellers shall have obtained the consent of
the non-Seller party to the Assumed Contract listed as Item D.3 on Schedule
3.09(b) hereto to the assignment of such contract and delivered a written copy

          (d) by the Sellers or by Buyer, at any time after April 30, 2002, if

and (g) of Section 3.12 hereof shall survive the Closing until the fifth

accordance with this Article IX prior to the applicable expiration date provided
above shall survive with respect to such claim or dispute until the resolution
thereof. The covenants and agreements made by any party pursuant to this
Agreement shall survive the Closing for 18 months, unless a longer period is
specifically set forth in such covenant or agreement.

          9.02. INDEMNIFICATION. (a) Sellers' Agreement to Indemnify. Subject to
the terms and conditions of this Article IX, the Sellers hereby agree to jointly
and severally indemnify, defend and hold harmless Buyer and its officers,
directors, employees, Affiliates, successors and permitted assigns (the "Buyer
Group"), from and against, and pay and/or reimburse them for, any and all
claims, whether or not the result of a Third Party Claim, and any and all
losses, claims, liabilities and damages (but excluding indirect damages, lost
profits or punitive damages), and reasonable and documented costs and expenses
(including reasonable attorneys' fees and reasonable costs of collection
hereunder) (collectively, "Damages"), incurred by any of the Buyer Group to the
extent arising from or attributable to (i) the breach of any representation or
warranty of the Sellers contained in this Agreement or the Other Agreements
(other than those that have expired as provided herein or therein); provided,
however, that in determining whether any such breach exists, such
representations and warranties shall be deemed also to have been made as of the
Closing Date and irrespective of any supplemented or amended disclosure made
pursuant to Section 5.18 hereof; provided, further, that if the Sellers shall
become aware prior to the Closing that any representation or warranty made by
the Sellers that is subject to a knowledge standard would not be true and
correct as of the date hereof were such knowledge standard removed, such
representation and warranty shall be deemed to have been breached for purposes
of this Section 9.02(a)(i); (ii) any breach of any covenant or agreement of the
Sellers contained in this Agreement or the Other Agreements; (iii) the Retained
Liabilities (including any liability imposed, by operation of law or otherwise,
on Buyer (as successor to or transferee of the U.S. Business) directly in
respect of pre-Closing actions or omissions of the Sellers or conditions
existing as of the Closing at the Facility, but in each case, only to the extent
such liabilities are not Assumed Liabilities); or (iv) any breach or
non-compliance with applicable bulk sales or similar laws in connection with the
transactions contemplated hereby. Claims by any of the Buyer Group under this
Section 9.02 are referred to individually as a "Buyer Claim" or collectively, as


                                       53


"Buyer Claims." Notwithstanding the foregoing or anything to the contrary
contained in this Agreement or any Other Agreement:

                  (A) Buyer's sole remedy in respect of any actual or alleged
         breach of the representations set forth in Section 3.05(d) (other than
         the first and second sentences thereof) or Section 3.03 (only to the
         extent relating to inventory) shall be limited to the procedures set
         forth in Section 2.02 hereof relating to the adjustment of the
         Inventory Purchase Price;

                  (B) in respect of any Buyer Claim under this Section 9.02(a)
         relating to a breach or alleged breach of any representation or
         warranty contained in Section 3.12 hereof (other than clauses (c) and
         (d) thereof), in each case notice in respect of which Buyer Claim is
         given in accordance with Section 9.03 hereof after the fifth
         anniversary of the Closing Date, there shall be a factual presumption
         that all Hazardous Substances that allegedly give rise to such Buyer
         Claim were disposed of or released by Buyer; and

                  (C) for purposes of this Article IX and Section 5.08 hereof
         only, Environmental Claims of any nature shall not be treated as
         Retained Liabilities and, accordingly, Buyer's sole remedy in respect
         of Environmental Claims shall be limited to claims for indemnification
         under Section 9.02(a)(i) hereof in respect of Damages incurred by any
         of the Buyer Group to the extent arising from or attributable to a
         breach of the representations and warranties set forth in Section 3.12
         hereof, and subject to all limitations applicable to indemnification
         under Section 9.02(a)(i) hereof set forth in this Article IX; provided,
         however, that the foregoing shall not limit Buyer's right, in respect
         of Third Party Claims, to assert that any such Environmental Claims are
         not liabilities assumed by Buyer hereunder.

          (b) BUYER'S AGREEMENT TO INDEMNIFY. Subject to the terms and
conditions of this Article IX, Buyer hereby agrees to indemnify, defend and hold
harmless the Sellers and their respective officers, directors, employees,
Affiliates, successors and permitted assigns (the "Seller Group"), from and
against, and pay and/or reimburse them for, any and all Damages incurred by any
of the Seller Group to the extent arising from or attributable to (i) the breach
of any representation or warranty of Buyer contained in this Agreement or the
Other Agreements (other than those that have expired as provided herein or
therein); (ii) any breach of any covenant or agreement of Buyer contained in
this Agreement or the Other Agreements; (iii) any liability or obligation of the
Seller Group arising in connection with the Business, to the extent they are
directly based upon or directly related to actions or omissions of Buyer that
shall have occurred following the Closing; or (iv) the Assumed Liabilities.
Claims by any of the Seller Group under this Section 9.02 are referred to
individually as a "Seller Claim" or collectively, as "Seller Claims."

          (c) TAX TREATMENT OF INDEMNIFICATION PAYMENTS. The Sellers and Buyer
agree to treat any indemnity payment made under this Article IX as an adjustment
to the Purchase Price for income tax purposes. Any such Purchase Price


                                       53


adjustment shall, to the maximum extent possible, be allocated to the assets or
property acquired to which such adjustment relates.

          9.03. PROCEDURES FOR INDEMNIFICATION. (a) In order for a member of the
Buyer Group or Seller Group, as the case may be, to be entitled to
indemnification provided for under this Agreement in respect of, arising out of
or involving a claim made by a third-party (a "Third Party Claim"), such
indemnified party must notify the indemnifying parties in writing, and in
reasonable detail, of the Third Party Claim within ten (10) days after receipt
by such indemnified party of written notice of the Third Party Claim; provided,
however, that the failure to provide timely and proper notice shall not limit
the indemnification provided hereunder except that the indemnification hereunder
shall be reduced by the financial effect, if any, of such failure (except that
an indemnifying party shall not be liable for any expenses incurred during the
period following such 10-day period in which the indemnified party failed to
give such notice). Thereafter, (i) the indemnified party shall promptly deliver
to the indemnifying parties (A) copies of all notices and documents (including
court papers) received by the indemnified party relating to the Third Party
Claim and (B) all available information and documentation necessary to support
and verify the claim asserted, and (ii) the indemnifying parties shall be given
reasonable access to the books and records in the possession or control of the
indemnified party or any of its Affiliates which any indemnifying party
reasonably determines to be related to, or reasonably necessary in the defense
of, such Third Party Claim.

          (b) If a Third Party Claim is made against an indemnified party, the
indemnifying parties will be entitled, at their own cost and expense, to
participate in the defense thereof and, if they so choose, to assume the defense
thereof with counsel reasonably selected by the indemnifying parties. If an
indemnifying party assumes such defense, the indemnified party shall have the
right to participate in the defense thereof and to employ counsel, at its own
cost and expense, separate from the counsel employed by the indemnifying
parties, it being understood that the indemnifying parties shall control such
defense and will not be liable to the indemnified party for any legal expenses
incurred by the indemnified party subsequent to the assumption by an
indemnifying party of the defense; provided, however, that the indemnifying
parties shall be liable for the reasonable fees of separate counsel for the
indemnified party (which counsel shall be reasonably acceptable to the
indemnifying parties) if, in the reasonable opinion of outside counsel for the
indemnified party (which counsel and opinion shall be reasonably acceptable to
the indemnifying parties), representation of the indemnifying parties and the
indemnified party in such matter by one counsel would create a conflict of
interest such that representation of the indemnifying parties and the
indemnified party in such matter by separate counsel is required under
applicable ethical rules governing legal representation. In any event, an
indemnifying party shall not be liable under this Agreement for the fees and
expenses of more than one firm of counsel employed by (and representing all) the
indemnified parties. Whether or not an indemnifying party chooses to assume the
defense of any Third Party Claim, all the parties hereto shall, and shall cause
their respective Affiliates to, cooperate in the defense or prosecution thereof
and to in good faith retain and furnish such records, information and testimony,
and attend such conferences, discovery proceedings, hearings, trials and
appeals, as may be reasonably requested by a party hereto in connection


                                       54


therewith. If an indemnifying party chooses to defend or prosecute any Third
Party Claim, the indemnifying party shall be authorized to consent to a
settlement of, or the entry of any judgment arising from, any such Third Party
Claim, and the indemnified party shall consent to a settlement of, or the entry
of any judgment arising from, such Third Party Claim; provided, however, that
the indemnifying party shall be authorized to so consent only if (A) it shall
pay or cause to be paid all amounts arising out of such settlement or judgment
concurrently with the effectiveness thereof; (B) it shall not encumber any of
the assets of any indemnified party or agree to any significant restriction or
condition that would apply to such indemnified party or to the conduct of that
indemnified party's business; (C) it shall obtain, as a condition of any
settlement or other resolution, a complete and irrevocable release of each
indemnified party; and (D) such settlement or judgment shall not require any (x)
admission of liability, fault or wrongdoing by any indemnified party or impose
any significant non-monetary obligation on any indemnified party (such as, by
way of example, and not in limitation, injunctive relief) or (y) admission or
statement that could reasonably be expected to materially impair, disparage or
otherwise adversely affect the business reputation of the indemnified party.
Except to the extent of the foregoing, no settlement or entry of judgment in
respect of any Third Party Claim shall be consented to by any indemnifying party
or indemnified party without the express prior written consent of the other
party (which consent shall not be unreasonably withheld or delayed). Whether or
not an indemnifying party shall have assumed the defense of a Third Party Claim,
the indemnified party shall not admit any liability with respect to, or settle,
compromise or discharge, such Third Party Claim without the indemnifying
parties' prior written consent (which consent shall not be unreasonably withheld
or delayed).

          9.04. LIMITATIONS. (a) Except with respect to any breaches of Section
3.11 hereof, Section 4.05 hereof, the first, second and third sentences of
Section 3.05(a) hereof, the first sentence of each of Sections 3.05(b) and
3.06(b) hereof, Section 3.05(e) hereof, Section 3.12 hereof, the first sentence
of 3.18(a) hereof and/or the third sentence of Section 3.14(a) hereof
(collectively, the "Excepted Breaches"), (x) neither Buyer Group nor Seller
Group may, subject to Section 8.02 hereof, assert any Buyer Claims or Seller
Claims with respect to Damages under Section 9.02(a)(i) hereof or Section
9.02(b)(i) hereof, as the case may be, until the aggregate amount of such Buyer
Claims or Seller Claims, as the case may be, for which the Sellers or Buyer,
respectively, are required to indemnify hereunder exceeds $2,000,000 (the
"Threshold Amount"), and (y) once the aggregate amount of Buyer Claims under
Section 9.02(a)(i) hereof or Seller Claims under Section 9.02(b)(i) hereof, as
the case may be, for which a party is required to indemnify hereunder, exceeds
the Threshold Amount, then the indemnified party shall, subject to the following
provisos, be entitled to recover from the indemnifying parties the entire amount
of such Buyer Claims or Seller Claims, as the case may be, including the
Threshold Amount (provided that with respect to any Excepted Breaches, all
Damages, irrespective of the Threshold Amount, shall be recoverable); provided,
however, that (i) the aggregate liability of Buyer with respect to Damages under
Section 9.02(b)(i) hereof shall not exceed $25,000,000 and (ii) the aggregate
liability of the Sellers with respect to Damages under Section 9.02(a)(i) hereof
(other than in respect of breaches of representations and warranties provided in
Section 3.12 hereof) shall not exceed $25,000,000 and the aggregate liability of


                                       55


the Sellers with respect to Damages under Section 9.02(a)(i), including breaches
of representations and warranties provided in Section 3.12 hereof, shall not
exceed $30,000,000.

         Notwithstanding the foregoing, Buyer shall bear the costs of building a
structure designed to cover any hazardous material drums located at the
Facility, which costs shall be specifically excluded from the indemnification
provisions hereof; provided, however, that Buyer's agreement to bear such costs
shall in no other way limit or diminish Buyer's ability to seek indemnification
hereunder.

          (b) Except (x) for the right to seek to specifically enforce the
covenants under this Agreement and the Other Agreements, (y) as specifically
provided in this Agreement or the Other Agreements and (z) for remedies that
cannot be waived as a matter of law, the sole and exclusive remedy of the Buyer
Group and the Seller Group for breaches of the representations, warranties,
covenants and agreements contained in this Agreement and in the Other Agreements
(other than the Supply Agreement), or any certificate delivered pursuant hereto
or thereto, shall be limited to the indemnification rights set forth in this
Article IX.

          (c) The amount of any Damages sustained by an indemnified party shall
be reduced by (i) any amount actually received by such party with respect
thereto under any insurance coverage or from any other party alleged to be
responsible therefor and (ii) the amount of any other monetary benefit realized
by an indemnified party directly relating thereto. Any indemnified party under
this Agreement shall use reasonable best efforts to collect any amounts
available under such insurance coverage and from such other allegedly
responsible parties (including, without limitation, pursuant to the
Indemnification Agreement). If an indemnified party realizes or receives an
amount under insurance coverage or from such other party with respect to Damages
sustained at any time subsequent to any indemnification provided pursuant to
this Article IX, then such indemnified party shall promptly reimburse the
applicable indemnifying party for any payment made or expense incurred by such
indemnifying party in connection with providing such indemnification up to such
amount realized or received by the indemnified party. Each indemnified party
shall take reasonable steps to mitigate any Damages upon becoming aware of any
event, circumstance or condition that would reasonably be expected to give rise
to Damages indemnifiable hereunder.

          (d) Indemnifiable Damages under Section 9.02(a)(i) hereof arising from
breaches of the representations and warranties in Section 3.12 hereof shall be
limited to the most cost-effective solution required to comply with applicable
Environmental Laws and the least stringent applicable remediation standards;
provided, however, that any such remediation standards applicable to the
Facility will allow the continued use of the Facility in substantially the same
manner as it was used immediately before the Closing Date. The Buyer Group shall
not be entitled to indemnification in respect of Damages to the extent based
upon diminution of the fair market value of the Facility. In respect of Damages
relating to operational or maintenance costs incurred by the Buyer Group to
operate any compliance equipment, the Buyer Group shall only be entitled to
indemnification in respect of the present value (discounted at the rate of seven
(7%) percent per annum) of such portion of such costs that relate directly and

                                       56


exclusively to remedying the breaches of representations and warranties in
Section 3.12 hereof that gave rise to such Damages, and subject further to the
other limitations set forth in this Article IX. The Sellers may elect (in
writing) to control any investigation or remediation arising from breaches of
Section 3.12(b), (c) or (d) hereof; provided, however, that such investigation
or remediation pursuant to Section 3.12(b) or (d) hereof shall be conducted
promptly and shall not materially interfere with Buyer's operation of the
Business. Buyer agrees to (i) cooperate with the Sellers to perform any
investigation or remediation; (ii) to place any deed notices or restrictions
that may be necessary; provided, that such deed notices or restrictions do not
significantly interfere with the continued use of the Facility or other property
in the same manner as it was used on or before the date of this Agreement; and
(iii) to maintain any institutional or engineering controls; provided, that the
present value (discounted at the rate of seven (7%) percent per annum) of such
portion of the cost for maintaining such controls that relates directly and
exclusively to such remediation shall (subject to the limitations set forth in
this Article IX) be paid for by the Sellers.

          9.05. INDEMNIFICATION FOR AIR PERMIT NON-COMPLIANCE. The Sellers
hereby agree to jointly and severally indemnify, defend and hold harmless the
Buyer Group from and against, and pay and/or reimburse the Buyer Group for, any
and all Damages incurred by any of the Buyer Group necessary for the Business,
as if operated at eighty one (81%) percent of its practical capacity for
manufacturing the products identified on Schedule 1.01(e)(i) hereto or
substantially similar products in a commercially reasonable and prudent product
mix and product scheduling, to comply with all applicable Environmental Laws, to
the extent that such Damages arise from or are attributable to conditions of
non-compliance referenced in Item 1 of Schedule 3.12(a) hereto (concerning
certain temperature requirements specified as Operational Restrictions in the
Additional Special Terms and Conditions section of the Permit To Install,
Application No. 01-7396, issued to the Facility by the Ohio Environmental
Protection Agency, effective October 1, 1998) (hereinafter, "Air Compliance").

          The Sellers shall have the right to control the scope and nature of
the method to achieve Air Compliance, including, without limitation, pursuing
permit modifications to achieve Air Compliance; provided, however, that: (1) the
Sellers' efforts shall cause the Facility to achieve compliance at the
above-stated capacity as soon as practicable; and in any event not later than
one year after the date of this Agreement; and (2) any modifications or
amendments to the permit do not impose additional operating, maintenance or
monitoring requirements on the Facility that would significantly interfere with
Buyer's ability to operate the Facility in substantially the same manner as of
the date of this Agreement. If the Sellers do not achieve such Air Compliance
within one year of this Agreement, or if any time sooner the Sellers fail to
make reasonable efforts to achieve such Air Compliance, Buyer may undertake, at
the Sellers' expense, actions that are necessary to achieve Air Compliance at
the above-stated capacity in a manner that is reasonable and cost effective
under the circumstances existing at the time. Provided that the Sellers have
made reasonable progress toward achieving Air Compliance, this one-year period
may be extended for a reasonable period of time to allow for construction and/or


                                       57


installation of equipment at the Facility. Any such extension must be approved
by Buyer and such approval must not be unreasonably withheld.

          Notwithstanding anything to the contrary contained herein,
indemnifiable Damages under this Section 9.05 shall include, without limitation,
any losses resulting from or caused by any interruption of operations of the
Business due to the Sellers' action (or inaction) in seeking to achieve Air
Compliance. Buyer shall use commercially reasonable efforts to mitigate any
Damages under this Section 9.05. The indemnification available under this
Section 9.05 is separate and apart from the indemnification available under
Section 9.02(a) hereof and shall not be counted toward any of the limitations
specified in Section 9.04(a) hereof.

          Buyer shall cooperate with the Sellers in connection herewith,
including, without limitation, executing and submitting any Permit amendment or
modification applications, or other documentation required to implement a method
to achieve Air Compliance, or providing employee training; provided, however,
that any such requirements do not significantly interfere with Buyer's ability
to operate the Facility in substantially the same manner as of the date of this
Agreement.

          Buyer shall have the right to participate in the process of achieving
Air Compliance and the Sellers shall keep Buyer informed of developments,
strategy and plans, including but not limited to, prior notice of and
opportunity to participate in all meetings or discussions with Governmental
Entities, and prior draft copies of all correspondence with and information
supplied to Governmental Entities, and the opportunity to comment thereon prior
to submission to Governmental Entities. The Sellers shall reasonably address
Buyer's comments. The Sellers shall provide Buyer with reasonable prior notice
of written designs or descriptions of any: capital improvements, and equipment
installations, modifications or upgrades, and the opportunity to comment thereon
prior to such methods being implemented, and the Sellers shall reasonably
address Buyer's comments. Buyer shall bear the cost of its participation and
such costs shall not be considered Damages. In the event any method of achieving
compliance also results in an additional benefit to the operations of the
Business, indemnifiable Damages shall be calculated after subtracting the value
of any benefits to the Business as such shall be reasonably negotiated and
agreed to at such time by Buyer and the Sellers.


                                    ARTICLE X

                                  MISCELLANEOUS

anticipation of, this Agreement and the consummation of the transactions
contemplated hereby.

          10.02. FURTHER ASSURANCES; COOPERATION. From time to time after the

party so requesting, the Sellers and Buyer agree to execute and deliver to such
requesting party such documents and take such other action as such requesting


                                       58


party may reasonably request in order to consummate more effectively the
transactions contemplated hereby. The Sellers and Buyer shall reasonably
cooperate with each other and provide each other with such assistance as
reasonably may be requested by either of them in connection with all reasonable
requests, including with respect to the prosecution and defense of claims and
perfecting title to, and possession of, the Assets and the Shares. The party
requesting assistance hereunder shall reimburse the party providing assistance
for all reasonable third-party out-of-pocket expenses incurred in providing such
assistance.

subject matter. This Agreement supersedes all prior agreements and
understandings, oral and written, with respect to its subject matter except for
Section 1 of that certain letter agreement, dated as of December 28, 2001, by
and between the Sellers and Buyer. BUYER ACKNOWLEDGES THAT, EXCEPT AS
SPECIFICALLY SET FORTH IN THIS AGREEMENT, THE SELLERS HAVE PROVIDED NO EXPRESS
OR IMPLIED REPRESENTATIONS OR WARRANTIES OF ANY KIND. Without limiting the
foregoing, Buyer acknowledges and agrees that, except to the extent provided in
Sections 3.03, 3.07, and 3.15 hereof, the Sellers are making no representations
or warranties with respect to the business, operations, properties, assets or

connection with the FineTech Agreement, for any period prior to June 6, 2001.

          (b) Items or information may be disclosed in the Schedules hereto
which the Sellers are not required to disclose under this Agreement; disclosure
of such items or information shall not affect (directly or indirectly) the
interpretation of this Agreement or the scope of the disclosure obligation under

construed as an admission that such information is "material" for any purpose.

          10.05. WAIVER OF BULK SALES REQUIREMENTS. Subject to Section
9.02(a)(iv) hereof, Buyer hereby waives compliance by the Sellers with any
bulk-sales notice requirements of applicable law.

          10.06. SEVERABILITY. Should any provision of this Agreement for any

requires, but no such assignment and/or delegation will relieve the assigning
and/or delegating party of its obligations hereunder in the event such assignee
and/or delegatee fails to satisfy such obligations in accordance with the terms
of this Agreement.


                                       60


          10.08. NO THIRD-PARTY BENEFICIARIES. This Agreement is not intended,
and shall not be deemed, to confer upon or give any Entity (including, without
limitation, any past or current employee of the Business) except the parties
hereto (and, with respect to Article IX hereof, the Buyer Group and the Seller
Group) and their respective successors and permitted assigns any remedy, claim,
liability, reimbursement, cause of action or other right under or by reason of
this Agreement.

          10.09. COUNTERPARTS. This Agreement may be executed in counterparts,
each of which shall be deemed an original, and all of which together shall
constitute one and the same instrument.

          10.10. INTERPRETATION. The article and Section headings contained in
this Agreement are solely for the purpose of reference, are not part of the
agreement of the parties and shall not in any way affect the meaning or
interpretation of this Agreement.

indirectly to this Agreement shall be governed by and construed in accordance

supplemented except pursuant to an instrument in writing signed by each of the
parties hereto. Any failure of the Sellers to comply with any term or provision
of this Agreement may be waived by Buyer at any time by an instrument in writing
signed on behalf of Buyer and any failure of Buyer to comply with any term or
provision of this Agreement may be waived by the Sellers at any time by an
instrument in writing signed on behalf of the Sellers. Any such waiver or
failure to insist upon strict compliance with such term or provision shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure to comply.
