consequences and that, under the circumstances, the waivers are reasonable and
not contrary to public policy or law. If, despite the foregoing, any of such

forever any subrogation claims or rights it would otherwise have or be entitled
to under this Guaranty or pursuant to applicable law as a result of any payment
made by Guarantor hereunder or otherwise.  Any amount paid to Guarantor on
account of any such subrogation rights shall be held in trust for the benefit of
Lessor and shall immediately be paid to Lessor and credited and applied against
the Obligations of Lessee, whether matured or unmatured, in accordance with the
terms of either of the Leases.  In furtherance of the foregoing, Guarantor shall
refrain from taking any action or commencing any proceeding against the Lessee

Account") maintained with Lessor and entitled "AMD Pledge Collateral Account for

of Default upon the occurrence of any event described in Section 5.1 above or to
