and interest on, the Guaranteed Amount. The liability and obligation of the

            8. The parties hereto acknowledge and agree that the name "Starwood

but not personally) under a Declaration of Trust dated August 25, 1969, as
amended and restated as of June 6, 1988 and as further amended and restated as
of January [6], 1999, and as the same has been or may be amended from time to
time thereafter, and that the parties hereto shall look solely to the Trust's

for obligations entered into on behalf of the Trust, and their respective
individual assets shall not be subject to the claims of any person relating to
such obligations. The foregoing shall govern all direct and indirect obligations
of the Trust under this First Modification.
