         Re:      Limited Partnership Agreement of Third Street
                  Partners, Ltd. (the "Partnership") of even date
                  herewith (the "Partnership Agreement")

Ladies and Gentlemen:

         This will confirm our agreement as follows, supplementing and amending
the captioned Partnership Agreement:

         1.       All capitalized terms used herein and not specifically defined
                  herein shall have the respective meanings assigned to those
                  terms in the Partnership Agreement.

         2.       Upon the closing of the acquisition by the Partnership of
                  title to the Property (or title to the Property other than the
                  Out Parcel), the Partnership (i) shall pay a brokerage
                  commission in the amount of $100,000.00 to C.B. Schwaderer,
                  Inc. and a brokerage commission in the amount of $50,000.000
                  to a firm (whose name and address will be provided by Boma)
                  with which David Yudell is affiliated; and (ii) will
                  indemnify, defend and hold harmless Boca, Boma and their
                  respective partners, members, and officers from and against
                  all claims, liabilities, losses, damages, costs and expenses
                  (including, without limitation, reasonable attorneys' fees and
                  disbursements) asserted against, suffered or incurred by any
                  of the foregoing indemnified parties by reason of any claims
                  for the brokerage commissions referred to in the preceding
                  clause (i). The Levitt Partners and the Related Partners will
                  make additional capital contributions to the extent funds are
                  needed by the Partnership in order to fund payment of all of
                  said brokerage commissions at said closing of title.

         3.       Supplementing Section 6.2.3(b)(xi) of the Partnership
                  Agreement, if Boca or its designee does not acquire title to
                  the Out Parcel by reason of the Seller's failure to deliver
                  title thereto in accordance with the Purchase Agreement, the
                  Partnership and Boca (or its designee) shall not enter into,
                  and accordingly, Boca shall not be required to pay for, the
                  Easement, and the Parking Space Note and Parking Space
                  Mortgage shall not be executed or delivered.

                  signed by the General Partners shall diminish or otherwise
                  affect the obligations of the Levitt Partners and the Related
                  Partners to make additional capital contributions as and when
                  required under the terms of the Partnership Agreement, as
                  modified and supplemented hereby.
