     NOW THEREFORE, in consideration of the premises and covenants contained
herein, the receipt and sufficiency of which are hereby acknowledged, the
parties agree as follows:

     1. Recitals; Effective Date. The recitals set forth above are incorporated
by reference herein and made a part hereof as if fully rewritten. This Agreement
shall be effective on the date of closings of the Vicksburg Property Contract
and Freeport Purchase Contract, and shall survive the closings of said
contracts.

     2. Vicksburg Property. In the event of a sale of the Vicksburg Property to
a New Vicksburg Buyer on or before the Outside Date, Vicksburg Buyer agrees to
pay to Vicksburg Seller on the date of the closing of the sale of the Vicksburg
Property to the New Vicksburg Buyer, as additional purchase price for the sale
of the Vicksburg Hotel under the Vicksburg Purchase Contract, the amount, if
any, equal to the sum of: (i) fourteen percent (14%) of the Net Proceeds from
the sale of the Vicksburg Property in excess of $3,500,000, capped in all events
at $140,000 (i.e., fourteen percent (14%) of the first $1,000,000 in Net
Proceeds in excess of $3,500,000); plus (ii) twenty percent (20%) of all Net
Proceeds from the sale of the Vicksburg Property in excess of $4,630,729.

     In the event that the Vicksburg Property has not been sold by the Outside

agree upon the value the Vicksburg Property as of the Outside Date, or failing
to mutually agree, they shall have the Vicksburg Property appraised as of the
Outside Date pursuant to the appraisal process set forth in Section 4(b) below
(the agreed on or appraised value as adjusted for capital improvements to the
subject Property as noted below being the "Vicksburg Outside Date Value"). No
later than forty-five (45) days following the date of determination of the
Vicksburg Outside Date Value, the Vicksburg Buyer shall pay to the Vicksburg
Seller the amount, if any, equal to the sum of: (i) fourteen percent (14%) of
the Vicksburg Outside Date Value in excess of $3,500,000, capped in all events
at $140,000; plus (ii) twenty percent (20%) of the Vicksburg Outside Date Value
in excess of $4,630,729.

     The terms of this Section 2 shall be superseded by the terms of Section 5
if applicable.

     3. Freeport Hotel. In the event of a sale of the Freeport Property to a New
Freeport Buyer on or before the Outside Date, Freeport Buyer agrees to pay to
Freeport Seller on the date of the closing of the sale of the Freeport Property
to the New Freeport Buyer, as additional purchase price for the sale of the
Freeport Hotel under the Freeport Purchase Contract the amount, if any, equal to
twenty percent (20%) of all Net Proceeds from the sale of the Freeport Property
in excess of $1,300,000.

     In the event that the Freeport Property has not been sold by the Outside
Date, then the Freeport Buyer and Freeport Seller shall endeavor to mutually
agree upon the value the Freeport Property as of the Outside Date, or failing to
mutually agree, they shall have the Freeport Property appraised as of the
Outside Date pursuant to the appraisal process set forth in Section 4(b) below
(the agreed on or appraised value as adjusted for capital improvements to the
subject


                                       2



Property as noted below being the "Freeport Outside Date Value"). No later than
ten (10) days following the date of determination of the Freeport Outside Date
Value, the Freeport Buyer shall pay to the Freeport Seller the amount, if any,
equal to twenty percent (20%) of the Vicksburg Outside Date Value in excess of
$1,300,000.


     Notwithstanding anything to the contrary contained herein, to the extent
that the Freeport Property is sold prior to the Vicksburg Property and the
Freeport Net Proceeds of sale of the Freeport Property to the Freeport Buyer
from the New Freeport Buyer, after satisfaction of all mortgage debt secured by
the Property are insufficient to pay the contingent purchase price payments
called for in this Section 3 in full, then the deficiency if any shall accrue
without interest and be payable by the Vicksburg Buyer upon the earlier of the
sale of the Vicksburg Property or the Outside Date, in addition to the other
monies, if any, otherwise owing from the Vicksburg Buyer to the Vicksburg Seller
per Section 2 hereof.


     The terms of this Section 3 shall be superseded by the terms of Section 5
below, if applicable.

     4. Computation Guidelines.

          (a) Net Proceeds. For purposes of computing "Net Proceeds" from the
     sale of a Property, there shall be: (i) added to the sales price the amount
     of direct or indirect compensation or fees paid or payable to the seller of
     the Property and/or any affiliate or designee of such seller, including but
     not limited to consulting fees, asset management fees, commissions, non
     competition covenant fees, etc. (collectively, "Affiliate Fees"); provided
     however, to the extent an Affiliate Fee is already included as a portion of
     the sales price of the Property (e.g., if three percent (3%) commission is
     payable by the seller of the Property to an affiliate of the Seller), then
     such Affiliate Fee shall not be added to the sales price of the Property
     for purposes of this Section 4(a)(i); and (ii) subtracted from the sales
     price the sum of the following: (A) all actual third party closing costs
     paid by the seller in connection with the sale of the Property; plus (B)
     all third party commissions paid in connection with the sale of the
     Property; plus (C) all capital expenditures incurred by the seller of the
     Property following the date of this Agreement through the date of sale (but
     in no event later than the fifth anniversary of the date hereof), as
     reduced to the extent of accumulated depreciation for those capital
     expenditures made over two years prior to the date of sale, all as computed
     in accordance with GAAP.

          (b) Appraised Value. In order to determine the fair market value of a
     Property as of the Outside Date, the Property in question shall be
     appraised as of the Outside Date by an appraiser mutually agreeable to the
     parties, or should they fail to agree upon an appraiser within ninety (90)
     days following the Outside Date, then by an appraiser selected by Cushman &
     Wakefield, Inc. (which may be Cushman & Wakefield, Inc.) For purposes of
     the contingent purchase price payments called for above, the appraised
     value shall be reduced as to each Property by the amount of the sum of: (i)
     capital expenditures made by the relevant owner during the two years
     preceding the Outside Date; plus (ii) the amount of capital expenditures
     made by the relevant owner during the first 3 years following the date
     hereof, as reduced by the accumulated depreciation with respect to



                                       3



     such expenditures from the date placed in service through the Outside Date,
     as computed in accordance with GAAP.

     5. Early Payment. Notwithstanding anything to the contrary contained
herein, Vicksburg Buyer and Freeport Buyer shall have the right to prepay in
their entirety all contingent purchase price amounts that would otherwise be due
and owing with respect to the Properties per Section 2 and Section 3 above by
tender of the cumulative sum of $340,000 (subject to dollar-for-dollar credit to
the extent of prior payments pursuant to Section 6) to the Vicksburg Seller and
to the Freeport Seller or their assigns, to be allocated among them as they deem
proper (the "Early Contingent Sum Payment") at any time prior to the Vicksburg
Sale Date (the date of such payment being the "Early Payment Date"); provided
that such Early Contingent Sum Payment is made prior to the Outside Date in one
lump sum (subject to the right to credit for Participation Proceeds payments
previously paid per the operation of Section 6 below), and provided further; if
a Property is under contract for sale on or before ninety (90) days following
the Early Payment Date and is sold pursuant to such contract or an extension or
modification thereof or a new contract with the buyer named therein or its
affiliates entered into within ninety (90) days following termination of the old
contract, then a new computation shall be made to determine: (i) the amount of
Participation Proceeds that would have been paid with respect to such Property
had the sale occurred on the Early Payment Date, plus (ii) the amount of
Participation Proceeds that would have been paid with respect to the other
Property based on the adjusted appraised value as of the Early Payment Date (as
computed in accordance with Section 4(b) above, except in lieu of using the
Outside Date, the Property will be valued as of the Early Payment Date, and the
reduction for capital expenditures shall be for the sum of all capital
expenditures made by the relevant owner during the two (2) years preceding the
Early Payment Date, plus the amount of the relevant owner's capital expenditures
as reduced by accumulated depreciation for the Property preceding the two (2)
year period), provided that if such other Property is also sold pursuant to a
contract of sale entered into on or before ninety (90) days following the Early
Payment Date, then the Net Proceeds from such sale (as adjusted per Section 4(a)
above) shall be used in lieu of appraised value; to the extent that the sum of
the amounts computed per subparagraphs (i) and (ii) immediately above exceed
$340,000 (such amount being the "Excess") then no later than the date of the
computation of said sum, the Freeport Buyer and Vicksburg Buyer jointly and
severally agree to pay the Excess as among the Vicksburg Seller and Freeport
Seller or their assigns) as they or their designee shall designate, or barring
any designation, the Excess shall be split equally among them.

     6. Refinancing. In the event that prior to the Outside Date a Property
owner refinances one of the Properties, then the net proceeds from such
refinancing (the "Refinancing Net Proceeds") shall be applied toward an initial
payment against the Participation Proceeds called for in Section 2 and Section 3
hereof as if they had constituted Net Proceeds from sale of the Property. Upon a
subsequent refinancing of the Property prior to the Outside Date or upon a sale
of the Property or valuation of the Property effective as of the Outside Date,
any payments made to the Vicksburg Seller or Freeport Seller or their assigns
per operation of the immediately preceding sentence shall be credited against
the Participation Proceeds otherwise payable hereunder; however, in no event
shall the Vicksburg Buyer or Freeport Buyer be entitled to a return of any such
Refinancing Net Proceeds previously made. For purposes hereof, the term
Refinancing Net Proceeds shall mean the proceeds available to a Property owner
upon refinancing of its Property, after payment of the following: (i) payoff of
debt secured by the


                                       4



Property in question; and (ii) payment of all nonaffiliated third-party costs
and expenses incurred in connection with effecting the refinancing, including
but not limited to appraisal fees, mortgage recording costs and legal fees.

be by hand delivery, by overnight courier or by telecopy confirmed by answerback
received. Notices shall be deemed given on the date sent for hand delivery and
telecopy, and the day after the date sent for overnight courier. All notices
