         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

                             SECTION 1. DEFINITIONS

        1.1 All capitalized terms used herein and not otherwise defined herein
shall have the meanings assigned to such terms in the Credit Agreement.

        1.2 The following terms used in this Agreement shall have the meanings
set forth below:

         "Forbearance Default" means any one the following: (a) the occurrence
of any Default or Event of Default (other than the Covenant Defaults and the
default caused by Borrower's failure to make its July 15, 2002 interest payment
pursuant to the Subordinated Debt Documents, if any the "Sub Debt Payment")
under the Credit Agreement; (b) the failure of Borrower or any Guarantor to
comply with any term, condition or covenant set forth in this Agreement; (c) any
representation made by Borrower or any Guarantor under or in connection with
this Agreement shall have been materially false or misleading as of the date
when made; (d) the filing of any petition (voluntary or involuntary) under the
insolvency or bankruptcy laws of the United States or any state with respect to
Borrower or any Guarantor or any of their respective affiliates or Subsidiaries;
provided however, that the filing of an involuntary petition shall not be a
Forbearance Default unless such petition shall not be dismissed or stayed for a
period of ten (10) days or more from the date of filing the petition, or an
order for relief shall have been entered; (e) Borrower or any Guarantor makes a
payment in respect of the Subordinated Debt; or (f) any holder of the
Subordinated Debt (or any agent or representative of such holder), institutes an
action or proceeding to collect or otherwise realize upon the Subordinated Debt
and such action or proceeding shall not be dismissed, stayed or bonded for a
period of twenty (20) days or more after the date of initiation of the action or
proceeding.

         "Termination Date" means the earliest to occur of (a) 5:00 p.m. Eastern
Standard time on September 27, 2002, or (b) the date upon which a Forbearance
Default occurs.

                         SECTION 2. AGREEMENT TO FORBEAR

        2.1 Provided that no Forbearance Default occurs, Agent and Lenders
hereby agree to forbear and refrain, through the Termination Date, from
exercising their respective rights and remedies under the Credit Agreement or
any other Loan Document that may exist because of the Covenant Defaults or a
default respecting the Sub Debt Payment.

        2.2 Nothing in this Agreement shall be construed as a waiver of the
Covenant Defaults, which defaults shall continue in existence subject only to
the agreement of Agent and Lenders, upon the occurrence of such Covenant
Defaults as set forth herein, not to enforce their respective rights and
remedies for a limited period of time as set forth herein. Notwithstanding the

<PAGE>

preceding sentence (and without in any manner limiting the generality or the
specific thereof), the occurrence of any Covenant Defaults or other defaults
identified herein shall only become Defaults or Events of Defaults for purposes
of the Credit Agreement on the Termination Date. Except as expressly provided
herein, the execution and delivery of this Agreement shall not: (a) constitute
an amendment, extension, modification, or waiver of any aspect of the Credit
Agreement or the other Loan Documents; (b) extend the terms of the Credit
Agreement or the due date of any of the Obligations; (c) give rise to any
obligation on the part of Agent or Lenders to extend, modify or waive any term
or condition of the Credit Agreement or any of the other Loan Documents; or (d)
give rise to any defenses or counterclaims to the right of Agent and Lenders to
compel payment of the Obligations or to otherwise enforce their respective
rights and remedies under the Credit Agreement and the other Loan Documents.
Except as expressly limited herein, Agent and Lenders hereby expressly reserve
all of their respective rights and remedies under the Loan Documents and under
applicable law with respect to such Covenant Defaults. Borrower and each
Guarantor expressly acknowledge that from and after the Termination Date, Agent
and Lenders shall be entitled to enforce the Loan Documents and require strict
compliance with all of the terms and provisions of the Credit Agreement and the
other Loan Documents.

                  SECTION 3. AMENDMENTS TO THE CREDIT AGREEMENT
