until all Obligations shall have been indefeasibly paid in full and all
Commitments shall have been terminated, the Secured Parties are hereby
irrevocably authorized (but not required) to:

         (i) enforce claims comprising Subordinated Claims in the name of the

         (ii) collect any assets of any Intercompany Borrower distributed,
divided or applied way of dividend or payment, and any securities issued, in
each case, on account of Subordinated Claims and apply the same, or the proceeds
of any realization upon the same that the Secured Parties in their discretion

<PAGE>

have been indefeasibly paid in full and all Commitments shall have been
terminated; provided, however, that the Secured Parties shall render any surplus

interplead such surplus with any court of competent jurisdiction.

         (iii) vote claims comprising Subordinated Claims to accept or reject
any plan of partial or complete liquidation, reorganization, arrangement,
composition or extension; and

         (iv) take generally any action in connection with any such Proceeding

proofs of claim and executing and delivering all necessary powers of attorney,
assignments or other instruments.

                  (c) Enforcement by the Subordinated Parties. After the
commencement of any Proceeding, the Subordinated Parties may inquire in writing
of the Secured Parties whether the Secured Parties intend to exercise their
rights set forth in clause (a) above with respect to any Subordinated Claims.
Should the Secured Parties fail, within a reasonable time after receipt of such
inquiry, either to file a proof of claim with respect to any Subordinated Claims
and to furnish a copy thereof to the Subordinated Parties, or to inform the
Subordinated Parties in writing that the Secured Parties intend to exercise
their rights to assert such Subordinated Claims in the manner provided in clause
(a) above, the Subordinated Parties may (but shall not be required to) proceed
to file a proof of claim with respect to such Subordinated Claims and take such
further steps with respect thereto, not inconsistent with this Agreement, as the
Subordinated Parties may deem proper.

                  (d) Subrogation. The Subordinated Parties shall not have any
subrogation or other rights as holders of Senior Claims, and each Subordinated

reimbursement or indemnity whatsoever and all rights of recourse to any security
for any Senior Claims, until such time as all Obligations shall have been
indefeasibly paid in full and all Commitments shall have been terminated.

Obligations and the termination of all Commitments, the Subordinated Parties
shall have been terminated. Subject to and from and after the indefeasible
payment in full of all Obligations and the termination of all Commitments, the
Subordinated parties shall be subrogated to any rights of the Secured Parties to
receive payments or distributions of cash, property or securities of any
Intercompany Borrower applicable to any Subordinated Claims until all amounts
owing on such Subordinated Claims shall be paid in full.
