                        DIVERSIFIED INVESTMENTS PORTFOLIO

                               FIRST AMENDMENT TO
                           PURCHASE AND SALE AGREEMENT

         THIS FIRST AMENDMENT TO PURCHASE AND SALE AGREEMENT (this "Amendment")
is made and entered into as of the 23rd day of December, 2003, by and among MHC
OPERATING LIMITED PARTNERSHIP (together with its affiliates, designees and
assigns, the "Purchaser"), an Illinois limited partnership having an address of
Two North Riverside Plaza, Suite 800, Chicago, Illinois 60606, DIVERSIFIED
INVESTMENTS SERVICES, LLC ("Diversified"), a Delaware limited liability company
having an address of 7625 Wisconsin Avenue, Suite 150, Bethesda, Maryland 20814,
and the Sellers, each having an address of c/o Diversified Investments Services,
LLC, 7625 Wisconsin Avenue, Suite 150, Bethesda, Maryland 20814.

                                R E C I T A L S:

         A.       The parties hereto have entered into that certain Purchase and
Sale Agreement dated as of December 8, 2003 (the "Purchase Agreement").
Capitalized terms used but not otherwise defined herein shall have the meanings
set forth in the Purchase Agreement.

         B.       The parties hereto desire to amend the Purchase Agreement as
hereinafter provided.

         THEREFORE, the parties hereto agree to amend the Purchase Agreement as
follows:

                               A G R E E M E N T:

         1.       CACTUS GARDENS. Sections 5.A. and 5.C.(v) are amended to
reflect that Purchaser has submitted a loan application to LaSalle Bank National
Association ("LaSalle") for a first mortgage loan to be secured by the Cactus
Gardens Property with a loan amount of $4,500,000 (the "Cactus Gardens Loan
Application"). The loan proceeds of $4,500,000 is based on preliminary
underwriting by LaSalle which is subject to further underwriting by LaSalle. As
soon as Purchaser and Seller receive approval from the servicer of the current
loan on the Cactus Gardens Property that such loan can be defeased within ninety
(90) days, Purchaser intends to enter into a rate lock agreement with LaSalle
for $4,500,000 for a loan for the Cactus Gardens Property. The Closing Date for
the Cactus Gardens Property shall occur on a date which is mutually agreed upon
by the parties hereto which is within the 90 day rate lock period but not later
than May 15, 2004. To induce Purchaser to enter into a rate lock agreement for
the loan for the Cactus Gardens Property, Seller hereby waives its right not to
sell the Cactus Gardens Property to Purchaser based on the proceeds of the loan
being below $5,050,000. Purchaser and Seller shall use commercially reasonable
efforts to cause LaSalle to increase the amount of the first mortgage loan on
the Cactus Gardens Property above $4,500,000 on the same terms contained in the
Cactus Gardens Loan Application attached hereto as Exhibit A (the
"Application"), provided that Purchaser agrees to pay the then current market
interest rate on that portion of the Cactus Gardens Property first mortgage loan
which exceeds $4,500,000 based on the terms of the Application (but without the
rate lock feature in place on the $4,500,000). Seller acknowledges that to the
extent that loan proceeds made available by LaSalle from the loan on

                                       1

the Cactus Gardens Property is materially less than $5,050,000, Purchaser shall
receive a credit against the Purchase Price allocated to the Cactus Gardens
Property in an amount equal to the amount by which said loan proceeds are less
than $5,050,000. For example, if such loan proceeds equal $5,000,000, Purchaser
will receive a credit against the Purchase Price equal to $50,000.

         2.       EFFECT. Except as amended herein, all terms and provisions
contained in the Purchase Agreement shall remain in full force and effect.

         3.       COUNTERPARTS. This Amendment may be executed in one or more
counterparts, all of which taken together shall constitute one and the same
agreement.

                            [SIGNATURE PAGES FOLLOW]

                                       2

         2.       Section 5 A of the Purchase Agreement is hereby amended to
read as follows:

                  5.       A CLOSING DATES. The closing ("Closing") of the
         transaction contemplated by this Agreement (i.e., the payment of the
         Purchase Price, the transfer and assignment of the Equity Interests,
         the transfer of title to the applicable Individual Properties (if
         applicable), and the satisfaction of all other terms and conditions of

         the transaction as contemplated by the Subscription Agreement (as
         referenced in Section 9 H hereof) on January 30, 2004 (the "Closing
         Date"). Notwithstanding anything contained herein to the contrary, and
         subject to the provisions of Section 5C(v) below, (i) the Closing Date
         for the Cactus Gardens Property shall occur upon a date which is
         mutually agreed upon by the parties hereto but which is after the
         expiration or waiver of the defeasance lockout period for the mortgage
         loan encumbering such property, but in no event earlier than January
         30, 2004 or later than May 15, 2004, (ii) in such event the Purchase
         Price allocated to the Cactus Gardens Property shall be $7,725,141, and
         (iii) an allocable portion of the Earnest Money based on Purchase Price
         allocations shall be held back as Earnest Money for the Cactus Gardens
         Closing. If the date of Closing above provided for falls on a Saturday,
         Sunday or legal holiday, the Closing Date shall take place on the next
         business day. The terms of the First Amendment shall continue to modify
         this Section 5 A.

         3.       Section 9 D of the Purchase Agreement is hereby deleted,
provided that Equity Seller of the _______________ property and the ____________
property shall jointly indemnify Purchaser for any loss or damage sustained by a
failure of the requirements set forth in Section 9 D, limited, however, to the
extent of $25,000 in the aggregate, and which amount shall be credited against
Seller's obligations under the Holdback Escrow provided in Section 7G.

         4.       Section 9 H of the Purchase Agreement is amended by adding the
following at the end thereof: "and the conditions precedent under the
Subscription Agreement have all been satisfied and the closing thereunder has
commenced."

         5.       EFFECT. Except as amended herein, all terms and provisions
contained in the Purchase Agreement shall remain in full force and effect.

         6.       COUNTERPARTS. This Amendment may be executed in one or more
counterparts, all of which taken together shall constitute one and the same
agreement.
