<PAGE>

Manhattan Bank USA, N.A. or LaSalle, provided that with respect to any Letters

         1.03 New Definitions. Section 1.1 [Definitions] of the Credit Agreement
is hereby amended by adding the following definitions in the appropriate

that ABN AMRO, pursuant to an Assignment and Assumption Agreement dated as of
the date hereof, has assigned to and LaSalle has assumed from ABN AMRO all of
ABN AMRO's rights and obligations as a Bank under the Credit Agreement, as more
fully set forth therein and, accordingly, LaSalle is one of the Bank parties to

the Borrower and the Banks hereby acknowledge receipt from ABN AMRO of, written
notice of its resignation as Agent. The Borrower and the Required Banks hereby

notice of such resignation under Section 10.14 of the Credit Agreement and the
Required Banks hereby appoint LaSalle to be Agent under, and as such term is
used and defined in, the Credit Agreement and Borrower hereby consents to the
appointment by the Required Banks of LaSalle as the successor Agent as such term
is used and defined in the Credit Agreement. Accordingly, the Banks and the
Borrower hereby acknowledge that: LaSalle shall, without any further action, be
deemed to be substituted as the Agent for ABN AMRO in such capacity on all the
other Loan Documents.

any number of counterparts each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument; and, delivery of
executed signature pages hereof by telecopy transmission from one party to

and enforced in accordance with the laws of the Commonwealth of Pennsylvania
without regard to its conflict of laws principles.

application thereof to any party hereto, shall be held invalid or unenforceable,
such invalidity or unenforceability shall not affect any other provisions or

unenforceable provision or application, and to this end the parties hereto agree
that the provisions of this Amendment are and shall be severable.
