            (a) ISP Hungary owns, beneficially and of record, all of the Shares
and the Israel Notes, free and clear of all Liens. The Shares represent all of
the issued capital stock of ISP Israel. Each Share is duly and validly
authorized and issued. Except for the Israel Notes, there are no outstanding
subscriptions, warrants, options, convertible securities or similar rights
relating to, or obligating ISP Israel to issue, any shares of capital stock of
or other equity interests in ISP Israel. The Seller Parties have delivered to
Buyer true and correct copies of the articles of association and all other
organizational documents of ISP Israel as in full force and effect on the date
hereof.

                  (i)   Except for the Israel Notes, there are no bonds,
debentures, notes or other indebtedness of ISP Israel having the right to vote
(or convertible into, or exchangeable for, securities having the right to vote)
on any matter on which any equityholder of ISP Israel may vote.

                  (ii)  Except as set forth on SCHEDULE 3.05(A)(II) hereto, ISP
Israel does not (a) own, directly or indirectly, legally or beneficially, any
shares of voting stock or other equity securities of any Entity, (b) have any
ownership interest, direct or indirect, legally or beneficially, in any Entity
or (c) have any obligation, direct or indirect, present or contingent, to
purchase or subscribe for any interest in, advance or loan monies to, or in any
way make any investment in, any Entity, or to share any profits or capital
investments in any other Entity.

                  (iii) Except for the restrictions set forth on SCHEDULE
3.05(A)(III) hereto, Buyer shall, at the Closing, own the Shares, without any
legal or contractual restrictions or limitations of any kind arising by or
through a Seller Party in respect of Buyer's ability to vote and/or transfer the
Shares, other than any restrictions under laws of general applicability.

            (b) There is no lease agreement to which ISP Israel is a party
entered into after June 6, 2001 relating to any item of equipment or other
property (other than the Real Property) that entails rental payments of more
than $20,000 per annum.

            (c) ISP Israel has good title to all material properties and assets
purported to be owned by it that (a) are reflected as assets on the 2001 Balance
Sheet or (b) not so reflected on the 2001 Balance Sheet because not required
under GAAP to be reflected thereon, but that are used by ISP Israel, or because
acquired by ISP Israel since the date of the 2001 Balance Sheet (in each case,


                                       10


except for inventory and other assets disposed of in the ordinary course of
business consistent with past practice since the date of the 2001 Balance
Sheet), free and clear of all Liens, except for Permitted Liens.

            (d) ISP Israel does not hold, nor has held on its behalf, any
inventory on consignment. No inventory of ISP Israel is subject to recall. All
items of inventory reflected on the 2001 Balance Sheet or acquired by ISP Israel
since the date of the 2001 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, except for obsolete, slow-moving
or defective items, all of which have been written down to their net realizable
value or have been adequately reserved against on the books and records of ISP
Israel (and on the 2001 Balance Sheet, to the extent applicable) in accordance
with GAAP, consistently applied in accordance with ISP Israel's past practice.
Since the date of the 2001 Balance Sheet, there has been no material increase by
ISP Israel in its sale of inventory or material write-off or write-down of the
value of its inventory inconsistent with past practice.

            (e) All of the accounts and notes receivable of ISP Israel,
including those reflected on the 2001 Balance Sheet, have arisen in the ordinary
course of business. Neither ISP Israel nor any of its Affiliates (including any
of the Seller Parties) has granted any security interest in such receivables or
any part thereof and, to the best knowledge of the Seller Parties, neither ISP
Israel nor any of its Affiliates (including any of the Seller Parties) has
received notice of any claim for recoupment, set-off or counter-claim in respect
of any such receivables. Except pursuant to the Termination Agreement, no
agreement for material deduction, discount or other deferred price adjustment
has been made with respect to any such receivables. All accounts payable of ISP
Israel, as reflected on the 2001 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. ISP Israel is not due any receivable
from, or liable for any account or note payable to, any of its officers,
directors or employees or any Affiliate or any officer, director, employee or
shareholder thereof, except for salaries, benefits and reimbursements or as set
forth on SCHEDULE 3.05(E) hereto.

any Entity challenging the ownership, validity, enforceability or use of any of
the Assigned Intangible Property. To the best knowledge of the Seller Parties,
no Entity is infringing upon any of the Assigned Intangible Property.

            (c) Except as set forth on SCHEDULE 3.06(C) hereto, ISP Israel owns,
free from any Liens (except for Permitted Liens), all of the Israel Intellectual
Property Rights. Since June 6, 2001, no claims have been asserted against ISP


                                       11


Israel, and none of the Seller Parties is aware of any basis for any claims, by
any Entity challenging the ownership, validity, enforceability or use of any of
the Israel Intellectual Property Rights. To the best knowledge of the Seller
Parties, no Entity is infringing upon any of the Israel Intellectual Property
Rights. Since June 6, 2001, the operation of the business of ISP Israel and/or
the use of the Israel Intellectual Property Rights by ISP Israel in the United
States, Europe and Israel in the operation of the business of ISP Israel has
not, in any material respect, infringed upon or violated any intellectual
property rights of any Entity (other than Buyer) and neither ISP Israel nor any
of its Affiliates (including any of the Seller Parties) has received written
notice of any such alleged infringement.

            3.07. LITIGATION. There is no material claim, action, lawsuit,
investigation or other arbitration or administrative proceeding pending or, to
the best knowledge of the Seller Parties, threatened against any of the Seller
Parties or ISP Israel at law, in equity or otherwise, in, before, or by any
Governmental Entity relating to or arising as a result of (i) the transactions
contemplated by this Agreement or (ii) the operation of the business of ISP
Israel. No representation is made in this Section 3.07 with respect to
Environmental Laws or Permits, which matters are covered by Section 3.12 hereof.

            3.08. TAXES. All material Tax Returns relating to ISP Israel
required to be filed by ISP Israel since June 6, 2001 have been filed with the
appropriate taxing Governmental Entities in all jurisdictions in which such Tax
Returns were required to be filed. All such Tax Returns are accurate in all
material respects; all Taxes relating to ISP Israel that are due and payable
have been fully paid or adequate reserves therefor have been established in
accordance with generally accepted accounting principles in Israel consistently
applied in accordance with past practices. Adequate provision has been made on
the 2001 Balance Sheet for the payment of all accrued and unpaid Taxes of ISP
Israel as of the date of the 2001 Balance Sheet. Since December 31, 2001, all
Taxes incurred by ISP Israel have been incurred in the ordinary course of
business and, to the extent payable, have been paid or adequate reserves
therefor have been established in accordance with generally accepted accounting
principles in Israel. Neither ISP Israel nor any of its Affiliates (including
any of the Seller Parties) has received from any taxing Governmental Entity
notice of an asserted deficiency or audit with respect to any Taxes or Tax
Returns owed by ISP Israel that has not been settled. There are no filed or, to
the knowledge of the Seller Parties, other Tax Liens on any of the properties or
other assets of ISP Israel, except Permitted Liens. ISP Israel is not a member
of a consolidated group for income tax purposes and is not a party to or
otherwise bound by any tax sharing, tax allocation, tax indemnification or
similar agreement. ISP Israel has been granted an "Approved Enterprise" partial
tax-exempt status by the Israel Investment Center and, to the best knowledge of
the Seller Parties, all actions necessary to preserve such partial tax-exempt
status have been taken.

Israel).

            (b) Except for the oral agreement for two (2) laboratory rooms at
Technion University, each of the Contracts required to be set forth on SCHEDULE

force and effect, enforceable by ISP Israel in accordance with its terms
(subject to the Bankruptcy and Equity Exception). Except as set forth on

thereunder and (ii) no party to an Israel Contract (other than ISP Israel) is,
to the best knowledge of the Seller Parties, in material default thereunder and,

transactions contemplated hereby will not cause, or result in, a default under,
termination of, or acceleration of any material rights (including change of
control payments) under any Israel Contract by ISP Israel. The Seller Parties
have delivered, or caused to be delivered, to Buyer true and complete copies of
all written Israel Contracts.

            3.10 COMPLIANCE WITH LAWS, PERMITS, ETC. ISP Israel, including all
of the products manufactured, distributed and/or marketed by it since June 6,

Plan or individual agreement that will or may result in any payment or

party indemnified under this Section 5.05(c) alleging the violation of any
applicable employment or labor law by Buyer or any of its Affiliates that

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, logos, URLs or domain names associated therewith, 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 specific prior written consent of a Seller
Party. Without limiting the foregoing, promptly, and in any event within twenty
(20) days following the Closing Date, Buyer shall remove from the Real Property

any ISP trademarks or logos, or any derivation, variation or simulation thereof.
Notwithstanding the foregoing, Buyer may, for a period of up to one hundred
twenty (120) days following the Closing Date, sell and/or distribute any
existing inventory of ISP Israel containing the names, logo 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.

            5.07. CONFIDENTIALITY. For a period of five (5) years from and after
the Closing Date, the Seller Parties shall treat and hold as confidential all
confidential information principally relating to the operations or affairs of
ISP Israel. Without limiting the foregoing, the Seller Parties shall not, and
shall cause each of their Affiliates not to, disclose any such confidential
information to any Entity (except, as consistent with the past practices of the
Seller Parties, to such Entity's employees, auditors, counsel, other
professional advisors or 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 the Seller Parties or any of their respective
Affiliates are 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 the Seller Parties shall promptly notify Buyer in writing of
such requirement so that Buyer, at its expense, may seek an appropriate
protective order or waive compliance with this Section 5.07. If, in the absence
of a protective order or receipt of a waiver hereunder, the Seller Parties or
any of their respective Affiliates are, on the advice of counsel, compelled to
disclose such confidential information, the Seller Parties or such Affiliate may
so disclose the confidential information; PROVIDED, HOWEVER, that the Seller
Parties or such Affiliate, as the case may be, shall use all reasonable efforts
to obtain reliable assurance that confidential treatment will be afforded to
such confidential information. The provisions of this Section 5.07 will not be
deemed to prohibit the disclosure by the Seller Parties of confidential
information relating to the operations or affairs of ISP Israel with Buyer's
prior written 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


                                       23


(vi) to provide services to Buyer in accordance with the terms and conditions of
this Agreement or any Other Agreement. The provisions of this Section 5.07 shall
not apply to information that (x) is or becomes publicly available other than as
a result of a disclosure by the Seller Parties (or their Affiliates) in
violation of this Section 5.07, (y) is or becomes available to the Seller
Parties or any of their respective Affiliates on a non-confidential basis from a
source that, to the knowledge of the Seller Parties, is not prohibited from
disclosing such information by a legal, contractual or fiduciary obligation or
(z) is or has been independently developed by the Seller Parties (other than in
connection with the business of ISP Israel).

            5.08. COOPERATION. The Seller Parties shall, and shall cause their
accountants to, reasonably cooperate with Buyer (at Buyer's expense) in
connection with any reasonable audit of the financial statements of ISP Israel

thereto, to be filed pursuant to the Securities and Exchange Act of 1934 in
connection with the transactions contemplated hereby. In addition, the Seller

Buyer's cost, in connection with the preparation of such audit and financial
statements, it being understood that the Seller Parties make no representations

            6.03. PROCEDURES FOR INDEMNIFICATION. (a) In order for a member of

reasonable detail, of the Third-Party Claim within ten (10) days after receipt

HOWEVER, that the failure to provide timely and proper notice shall not limit

hereunder shall be reduced by the financial effect, if any, of such failure (and
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
shall have 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 reasonably 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


                                       25


in the possession or control of the indemnified party or any of its Affiliates
that 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 (1) 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 (1) firm of counsel employed by (and representing all
of) 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 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, or the entry of any judgment arising from, such Third-Party Claim;
PROVIDED, HOWEVER, that the indemnifying party shall be authorized to so consent
without the prior written consent of the indemnified party 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 in respect of such claim; 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. No indemnified party shall admit any


                                       26


liability with respect to or settle or compromise (or consent to the settlement
of or entry of any judgment arising from) any Third-Party Claim without the
express prior written consent of the indemnifying party.

            6.04. LIMITATIONS. (a) Except with respect to any breaches of
Section 3.11 hereof, Section 4.05 hereof, Sections 3.04(iv), (vi) and (vii)
hereof, the first, second and fourth sentences of Section 3.05(a) hereof, the
first sentence of Section 3.06(b) hereof, the first sentence of 3.17(a) hereof
and Section 3.19 hereof (collectively, the "Excepted Breaches"), (x) neither
Buyer Group nor Seller Group may recover Damages in respect of any Buyer Claims
or Seller Claims with respect to Damages under Section 6.02(a)(i) hereof or
Section 6.02(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 Seller
Parties or Buyer, respectively, are required hereunder to indemnify exceeds
$640,000 (the "Threshold Amount"), and (y) once the aggregate amount of Buyer
Claims under Section 6.02(a)(i) hereof or Seller Claims under Section 6.02(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 subject to the following provisos); PROVIDED, HOWEVER, that (i) the
aggregate liability of Buyer with respect to Damages under Section 6.02(b)(i)
hereof in respect of the breach(es) of any representations or warranties
contained in this Agreement or in any Other Agreement shall not exceed
$8,000,000, (ii) the aggregate liability of the Seller Parties with respect to
Damages under Section 6.02(a)(i) hereof in respect of the breach(es) of any
representations or warranties contained in this Agreement (other than in respect
of breach(es) of any representations and warranties provided in Section 3.12
hereof) or in any Other Agreement shall not exceed $8,000,000 and (iii) the
aggregate liability of the Seller Parties with respect to Damages under Section
6.02(a)(i) in respect of the breach(es) of any representations or warranties
contained in this Agreement, including breach(es) of the representations and
warranties provided in Section 3.12 hereof, shall not exceed $9,600,000.

            (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 each of
the Buyer Group and the Seller Group for breaches of the representations,
warranties, covenants and agreements contained in this Agreement and the Other
Agreements shall be limited to the indemnification rights set forth in this
Article VI.

            (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


                                       27


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 VI, 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.

            (d) 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.

            (e) Damages indemnifiable under Section 6.02(a)(i) hereof arising
from any breach(es) 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. The Seller Parties may elect (in writing) to control any
investigation or remediation arising from breaches of Section 3.12 hereof;
PROVIDED, HOWEVER, that such investigation or remediation shall be conducted
promptly and shall not materially interfere with Buyer's operation of the
business of ISP Israel. Buyer agrees to cooperate with the Seller Parties in
connection with any investigation or remediation.

            (f) In respect of any Buyer Claim under Section 6.02(a)(i) hereof
relating to a breach or alleged breach of any representation or warranty
contained in Section 3.12(b) hereof, notice in respect of which Buyer Claim has
been given in accordance with Section 6.03 hereof, after the fifth (5th)
anniversary of the Closing Date, there shall be a factual presumption that all
Hazardous Substances that allegedly gave rise to such Buyer Claim were disposed
of or released after the Closing.

of the parties hereto with respect to their subject matter. This Agreement
supersedes all prior agreements and understandings, oral and written, with
respect to its subject matter. Notwithstanding the foregoing, all information
disclosed to Buyer in connection with the transactions contemplated hereby
(other than any information principally in respect of, related to, or in
connection with ISP Israel and the Assigned Intangible Property) shall be
subject to the provisions of the Confidentiality Agreement, previously executed
by Buyer and an Affiliate of the Seller Parties. BUYER ACKNOWLEDGES THAT, EXCEPT
AS SPECIFICALLY SET FORTH IN THIS AGREEMENT, THE SELLER PARTIES 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 and the penultimate sentence of Section 3.10
hereof, the Seller Parties are making no representations or warranties with

            (b) Items or information may be disclosed in the Schedules hereto
that the Seller Parties 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 this Agreement. In addition, inclusion of such information
herein shall not be construed as an admission that such information is
"material" for any purpose.

            7.05. SEVERABILITY. Should any provision of this Agreement for any
reason be declared invalid or unenforceable, such decision shall not affect the
validity or enforceability of any of the other provisions of this Agreement,
which other provisions shall remain in full force and effect and be enforced to
the fullest extent permitted by law.

            7.06. BINDING EFFECT; ASSIGNMENT. This Agreement and all of the
provisions hereof shall be binding upon and inure to the benefit of the parties
and their respective successors and permitted assigns. Neither this Agreement
nor any of the rights, interests or obligations hereunder shall be assigned or
delegated, directly or indirectly, by any party without the prior written
consent of the other parties; PROVIDED, HOWEVER, that any party may assign
and/or delegate this Agreement and any or all of the rights, interests and
obligations hereunder to any of its Affiliates, and upon any such permitted
assignment and/or delegation, the references in this Agreement to the assigning
and/or delegating party shall also apply to any assignee and/or delegatee unless
the context otherwise requires, but no such assignment and/or delegation will
relieve the assigning and/or delegating party of its obligations hereunder in

(and, with respect to Article VI hereof, the Buyer Group and the Seller Group)
and their respective successors and permitted assigns, any remedy, claim,


                                       30


liability, reimbursement, cause of action or other right under or by reason of
this Agreement.

            7.08. 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.

            7.09. 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.

            7.10. GOVERNING LAW. This Agreement and any claim related directly
or indirectly to this Agreement shall be governed by and construed in accordance
with the laws of the State of New York. Any legal action, suit or proceeding, in
equity or at law, arising out of or relating to this Agreement or the agreements
contemplated hereby or the transactions contemplated hereby or thereby shall be
instituted exclusively in the State or Federal courts located in the State and
County of New York and each party agrees not to assert, by way of motion, as a
defense or otherwise, in any such action, suit or proceeding, any claim that
such party is not subject personally to the jurisdiction of any such court, that
the action, suit or proceeding is brought in an inconvenient forum, that the
venue of the action, suit or proceeding is improper or should be transferred, or
that this Agreement or the subject matter hereof may not be enforced in or by
any such court. Each party further irrevocably submits to the jurisdiction of
any such court in any such action, suit or proceeding. Any and all service of
process and any other notice in any such action, suit or proceeding shall be
effective against any party if given personally or by registered or certified
mail, return receipt requested or by any other means of mail that requires a
signed receipt, postage prepaid, mailed to such party as herein provided.
Nothing herein contained shall be deemed to affect or limit the right of any
party to serve process in any other manner permitted by applicable law.

            7.11. AMENDMENTS. This Agreement may not be amended, modified or
supplemented except pursuant to an instrument in writing signed by each of the
parties. Any failure of the Seller Parties 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 Seller Parties at any time by
an instrument in writing signed on behalf of the Seller Parties. 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.

                            [SIGNATURE PAGE FOLLOWS]
