         (1) Issuer, Grantor and Secured Party are parties to the HAS Agreement

Agreement), including the Contribution Notes. Pursuant to a letter agreement
dated November 6, 2000, as amended on May 23, 2001 and October 18, 2001, Secured

its right to obtain the deed of trust on the Mortgaged Property, the Grantor has
offered to provide the Collateral described below, and Secured Party has agreed
to accept such Collateral in lieu of and in substitution for the deed of trust.

thereof in one or more parcels at public or private sale, at any of the Secured

Grantor agrees that, to the extent notice of sale shall be required by law, at
least ten days' notice to the Grantor of the time and place of any public sale
or the time after which any private sale is to be made shall constitute
reasonable notification. The Secured Party shall not be obligated to make any
sale of Collateral regardless of notice of sale having been given. The Secured
Party may adjourn any public or private sale from time to time by announcement
at the time and place fixed therefor, and such sale may, without further notice,

and/or then or at any time thereafter applied in whole or in part by the Secured
Party against, all or any part of the Secured Obligations. Any surplus of such
cash or cash proceeds held by the Secured Party and remaining after payment in
full of all such Secured Obligations shall be paid over to the Grantor or to
whomsoever shall be lawfully entitled to receive such surplus.
