         Re:  Fourth Amendment to Financing Agreements ("Fourth Amendment")

Gentlemen:

         Reference is made to the Amended and Restated Loan and Security
Agreement dated July 1, 1995, between you and the undersigned as amended (the
"Loan Agreement"). All capitalized terms not otherwise defined herein shall have
the meanings given such terms in the Loan Agreement.

         Borrower has requested that Lender agree to extend the term of the Loan
Agreement for three months and the Lender has agreed to do so, subject to the
terms and conditions of this Amendment. Subject to the terms and conditions
hereof, the Lender agrees with the Borrower as follows:

         (1)  Section 1.21 of the Loan Agreement is amended by deleting the
Section in its entirety and by substituting the following in lieu thereof:

                  "1.21"  Maximum Credit shall mean the amount of $70,000,000.

         (2)  Section 12.1(a) of the Loan Agreement is amended by deleting the
the first sentence thereof and by substituting the following sentence in lieu
thereof:

                  "This Agreement and the other Financing Agreements shall
                  become effective as of the date set forth on the first page
                  hereof and shall continue in full force and effect for a term
                  ending on October 1, 1998 (the "Renewal Date"), and from year
                  to year thereafter, unless sooner terminated pursuant to the
                  terms hereof; provided that Lender may, at its option, extend
                  the first Renewal Date for an additional year by giving
                  Borrower notice at least ninety (90) days prior to the first
                  Renewal Date.

         The foregoing amendment to Section 12.1(a) was effective as of
September 1, 1997.

         (3)  In connection with the execution and delivery of this Fourth
Amendment the Borrower and Guarantor shall furnish to the Lender upon Lender's
request certified copies of all requisite corporate action and proceedings of
the Borrower and Guarantor in connection with this Fourth Amendment and a legal
opinion of Borrower's and Guarantor's counsel as to the due authorization of
this Fourth Amendment and the enforceability hereof.

         (4)  Borrower confirms and agrees that (a) all representations and
warranties contained in the Loan Agreement and in the other Financing Agreements
are on the date hereof true and correct in all material respects (except for
changes that have occurred as permitted by the covenants in Section 9 of the
Loan Agreement or as permitted under this Fourth Amendment), and (b) it is
unconditionally liable for the punctual and full payment of all Obligations,
including, without limitation, all charges, fees, expenses and costs (including
attorneys' fees and expenses) under the Financing Agreements, and that Borrower
has no defenses, counterclaims or setoffs with respect to full, complete and
timely payment of all Obligations.

         (5)  Guarantor, for value received, hereby assents to the Borrower's
execution and delivery of this Fourth Amendment, and to the performance by the
Borrower of its agreements and obligations hereunder. This Fourth Amendment and
the performance or consummation of any transaction or matter contemplated under
this Amendment, shall not limit, restrict, extinguish or otherwise impair the
Guarantor's liability to Lender with respect to the payment and other
performance obligations of the Guarantor pursuant to the Guarantee, dated July
1, 1995 executed for the benefit of Lender. Guarantor acknowledges that it is
unconditionally liable to Lender for the full and complete payment of all
Obligations including, without limitation, all charges, fees, expenses and costs
(including attorney's fees and expenses) under the Financing Agreements and that
Guarantor has no defenses, counterclaims or setoffs with respect to full,
complete and timely payment of any and all Obligations.

         (6)  Borrower hereby agrees to pay to Lender all reasonable attorney's
fees and costs which have been incurred or may in the future be incurred by
Lender in connection with the negotiation and preparation of this Fourth
Amendment and any other documents and agreements prepared in connection with
this Fourth Amendment. The Borrower confirms that the Financing Agreements
remain in full force and effect without amendment or modification of any kind,
except for the amendments explicitly set forth herein. The Borrower further
confirms that after giving effect to this Fourth Amendment, no Event of Default
or events which with notice or the passage of time or both would constitute an
Event of Default have occurred and are continuing. The execution and delivery of
this Fourth Amendment by Lender shall not be construed as a waiver by Lender of
any Event of Default under the Financing Agreements. This Fourth Amendment shall
be deemed to be a Financing Agreement and, together with the other Financing
Agreements, constitute the entire agreement between the parties with respect to
the subject matter hereof and supersedes all prior dealings, correspondence,
conversations or communications between the parties with respect to the subject
matter hereof.
