                           b. the creation of CPVC and Export as wholly-owned
subsidiaries of CS Company, which consent is granted pursuant to Section 6.12(a)
of the Credit Agreement;

                           c. the intercompany transfers between the Borrower

connection with export sales;

                           d. the creation of additional liens disclosed on

guarantees thereof identified on Schedule A hereto, otherwise prohibited
pursuant to Section 6.19 of the Credit Agreement;

                  6. Delivery of Additional Agreements and Instruments. Obligors
covenant and agree that, within ten (10) days after the date hereof, they will
deliver or will cause to be delivered to the Bank a Guaranty Agreement by CPVC
in favor of the Bank, in form and substance satisfactory to the Bank:

                  7. Reaffirmation. Except as amended hereby, all of the terms,
covenants and conditions of the Credit Agreement and each of the other Credit
Documents (including, but not limited to, provisions relating to any authority
granted to the Bank to confess judgment against the Borrower and any waiver of
the right to trial by jury, if any) are ratified, reaffirmed and confirmed and
shall continue in full force and effect as therein written and are not intended
to be re-enacted as of the above date, but rather to be effective as of the
original date of such documents.

                  8. Confirmation of Guaranties. Each of the Original
Guarantors (other than Sprink) hereby reaffirms and ratifies all of the terms,
covenants, and conditions contained in each of their respective Guarantees and
confirms that such Guarantees are binding and enforceable against the Guarantors
as if such Guarantees had been executed as of the date hereof.

                  9. Continuation of Mortgages and Security Interests.

                           a. Borrower hereby reaffirms and ratifies all of the
terms, covenants and conditions contained in the Mortgage and confirms that such
Mortgage is binding, enforceable against Borrower and in full force and effect,
and continues to secure all of Borrowers' obligations under the Credit
Documents, as such obligations have been modified hereby;

                           b. The Borrower, as successor to Sprink in accordance
with the requirements of Section 6.12(a) of the Credit Agreement, hereby
assumes, reaffirms and ratifies all of the terms, covenants, and conditions
contained in the Guarantor Security Agreement and confirms that such Guarantor
Security Agreement is binding and enforceable against the Borrower and in full
force and effect and continues to secure all of such Guarantors' obligations
under the Credit Documents as such obligations have been modified hereto.

                  10. Binding Effect. This Amendment shall be binding upon and
inure to the benefit of the Obligors and the Bank and their respective
successors and assigns; provided, however, that the Obligors may not assign any
of their rights, nor delegate any of their obligations, under this Amendment
without the prior written consent of the Bank and any purported assignment or
delegation absent such consent shall be void. The Bank may at any time assign or
otherwise transfer (by participation or otherwise) any or all of its rights, or
delegate any or all of its obligations, hereunder.

                  11. Counterparts; Effectiveness. This Amendment may be
executed in any number of counterparts and by the different parties on separate
counterparts. Each such counterpart shall be deemed to be an original, but all
such counterparts shall together constitute one and the same agreement. This
Amendment shall be deemed to have been executed and delivered when the Bank has
received counterparts hereof executed by all parties listed on the signature
page(s) hereto.

                  12. Amendment and Waiver. No amendment or modification of this
Amendment, and no waiver of any one or more of the provisions hereof shall be
effective unless set forth in a writing and signed by the parties hereto.

                  13. Governing Law. This Amendment shall be governed by and
construed in accordance with the internal laws of the Commonwealth of
Pennsylvania without reference to conflict of laws principles.

                  14. Severability. Any provision of this Amendment that is held
to be inoperative, unenforceable, voidable or invalid in any jurisdiction shall,
as to that jurisdiction, be ineffective, unenforceable, void or invalid without
affecting the remaining provisions in that or any other jurisdiction, and to
this end the provisions of this Amendment are declared to be severable.

                  15. Judicial Proceedings. Each party to this Amendment agrees
that any suit, action or proceeding, whether claim or counterclaim, brought or
instituted by any party hereto or any successor or assign of any party, on or
with respect to this Amendment, the documents, instruments and agreements
executed in connection herewith, the Credit Documents or the dealings of the
parties with respect hereto and thereto, shall be tried only by a court and not
by a jury. EACH PARTY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY
RIGHT TO A TRIAL BY JURY IN ANY SUCH SUIT, ACTION OR PROCEEDING. Further, each
party waives any right it may have to claim or recover, in any such suit, action
or proceeding, any special, exemplary, punitive or consequential damages or
damages other than, or in addition to, actual damages. THE OBLIGORS ACKNOWLEDGE
AND AGREE THAT THIS SECTION IS A SPECIFIC AND MATERIAL ASPECT OF THIS AMENDMENT
AND THAT THE BANK WOULD NOT ENTER INTO THIS AMENDMENT IF THE WAIVERS SET FORTH
IN THIS SECTION WERE NOT A PART OF THIS AMENDMENT.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Amendment to be duly executed and delivered as of the day and year first above
written.
