     IN CONSIDERATION of $10.00 (ten dollars) paid by Fitzgeralds to Scout, and
for other good and valuable consideration, the parties agree as follows:

     2.1  Assignment. Pursuant to the Purchase Agreement referenced in Section

leasehold estate created under the Ground Lease, and (b) all of its fee simple
interest in and to the Leasehold Improvements, subject to matters now appearing
of record and the rights of the Lessor under the Subject Lease. The parties
agree that from and after the date hereof Scout shall have no further right,
title or interest in and to the Subject Lease, the leasehold estate thereunder,
or such Leasehold Improvements. Fitzgeralds shall be and become the lessee
under the Subject Lease and the owner of the fee simple title to the Leasehold
Improvements; provided, however, this Agreement is conditional upon the
assumption by Fitzgeralds under Section 2.2 hereof of all obligations of Scout
under the Subject Lease and the consent by G and S Investment to this
Agreement.

     2.2  Acceptance of Assignment and Assumption of Obligations. Fitzgeralds
hereby expressly accepts the assignment of Scout's leasehold interest under the
Subject Lease and the conveyance of Scout's fee simple interest in the Leasehold
Improvements. Fitzgeralds hereby expressly assumes all of Scout's obligations
under the Subject Lease arising from and after the date that each party hereto
has executed this Agreement and that G and S investment has consented to this
Agreement (the "Effective Date"). Fitzgeralds hereby agrees to defend,
indemnify, and hold Scout harmless from and against any and all claims which may
hereafter arise under and by virtue of the Subject Lease and Fitzgeralds'

hereby agrees to defend, indemnify and hold Fitzgeralds harmless

                                                                               4
<PAGE>   5
from and against any and all claims which may arise or have arisen under and by
virtue of the Subject Lease and Scout's ownership of the Leasehold Improvements
prior to the Effective Date.

     2.3 Representations and Warranties. Scout represents and warrants to
Fitzgeralds that Scout has not previously assigned all or part of its leasehold
interest under the Subject Lease or its fee simple interest in the Leasehold
Improvements, that no portion of such lessee's interest or leasehold interest or
property interest has been the subject of any security interest, collateral
assignment or conveyance other than the Deed of Trust and related security
instruments in favor of Scout; and that the Subject Lease is still in full force
and effect in accordance with the original terms and conditions of the Subject
Lease. Scout further represents and warrants to Fitzgeralds that Scout has full
right, power and authority to execute this Assignment and the same does not
conflict with any agreement, judgment, order, decree, rule, regulation or other
legal obligation under which Scout is bound.

     2.4 Payments to G and S Investment. Scout agrees to pay the minimum rental
due each month to G and S Investment together with such other amounts as may be
due in accordance with the terms of the Subject Lease; provided, however,
Scout's agreement to pay G and S Investment shall in no way be construed as a
release of Fitzgeralds' obligations hereunder and under the Subject Lease, and
Fitzgeralds shall pay the minimum rental due each month to Scout together with
such other amounts as may be due in accordance with the terms of the Subject
Lease. G and S Investment shall have the option at any time during the term of
the Subject Lease upon prior written notice thereof to require that the minimum
rental due each month together with such other amounts as may be due in
accordance with the terms of the Subject Lease be paid directly by Fitzgeralds
to G and S Investment.
