principal or interest in respect of the Notes, or any Collateral securing the
Notes, where applicable. Rather, each of the Lenders hereby acknowledges and
agrees that its rights and priority are PARI PASSU with the rights and priority

relative times of attachment or perfection thereof or the order of filing of

                  2.2 NOTICES OF DEFAULT. Each of the Lenders shall provide a
copy to Collateral Agent and each of the other Lenders of any written notice

                                      -2-
<PAGE>

                  2.3 DISPOSITION OF BORROWER'S ASSETS. In the event of (i) an
Event of Default, (ii) any insolvency, bankruptcy, receivership, liquidation,
reorganization, assignment for the benefit of creditors or other similar
proceeding relating to the Borrower, whether voluntary or involuntary, (iii) any
proceeding for the voluntary liquidation, dissolution or other winding-up of the
Borrower, whether involving insolvency or bankruptcy proceedings or not, or (iv)
any attachment of, foreclosure on, or other judicial action with respect to all
or any portion of the assets of the Borrower, or any transfer of such assets in
lieu of any such judicial action, or any creation of any lien, security
interest, mortgage, or deed of trust on any such assets other than in favor of
the Senior Lenders, then, and in any such event, any payment or other
distribution of any character, whether in cash, securities or other property out
of or in respect of the assets of the Borrower or any proceeds thereof or any
such security to which the Lenders are entitled, shall be shared by the Lenders
on a PARI PASSU basis with the amount thereto to which each such Lender is
entitled determined in accordance with the Pledge Agreement, the Security
Agreements and the Continuing Guarantees; PROVIDED, HOWEVER, that no Lender
shall take any action without written notice to Collateral Agent and the other
Lenders.

                  2.4 PAYMENTS TO BE HELD IN TRUST. If any Lender shall have
received any payment, distribution or security out of any of the assets of the
Borrower, whether arising out of or as a result of any event described in
SECTION 2.3 above or otherwise, the receiving party thereof shall promptly
provide Collateral Agent and each of the Lenders a clear and detailed accounting
thereof, and shall promptly take all action necessary to implement the sharing
contemplated by SECTION 2.3 above and by the Pledge Agreement, the Security
Agreements and the Continuing Guarantees. Any such payment, distribution or
security so received shall be deemed to be held in trust by the receiving party
thereof for the benefit of the Lenders until such sharing has been implemented
and completed as contemplated by SECTION 2.3 above and by the Pledge Agreement,
the Security Agreements and the Continuing Guarantees.

                  2.5 COOPERATION. Each of the Lenders agrees to use reasonable
best efforts to cooperate with one another in the realization upon and
liquidation of the assets of Borrower following an Event of Default, and to
promptly advise Collateral Agent and the other Lenders of any actions taken with
respect thereto, or of any modification or amendment of any or all of the
documents with respect to the Indebtedness; PROVIDED, HOWEVER, that no Lender
shall, enter into any such modification or amendment that would (i) extend the
term of such Indebtedness, (ii) increase the applicable rate of interest
thereunder, or (iii) increase the amount of Borrower's indebtedness thereunder,
without the prior written approval of the other Lenders.

         3. RIGHT TO AMEND, ETC. Any demand for payment of any Indebtedness or
delivery of collateral from Borrower upon the occurrence of an Event of Default
made by any Lender may be rescinded in whole or in part by such Lender. Lenders
may exercise or refrain from exercising any rights or remedies against the
Borrower and others, if any, liable under the Indebtedness. The Indebtedness
shall conclusively be deemed to have been created, contracted and incurred and
permitted to remain outstanding in reliance upon the provisions of this
Agreement.
