Attn.: Steven H. Levin, Esq.

Dear Mr. Levin:

        Lender has approved the Loan in the amount set forth below from Lender to you or your assignee(s) as permitted below (as applicable, “Borrower”), provided that all of the conditions to the funding of the Loan as set forth herein are satisfied. The Loan shall be used for (a) the purchase of the Santa Fe Property by Borrower pursuant to that certain Agreement of Sale and Purchase dated as of August 10, 2004, between Mack-Cali Texas Property L.P. as seller and Centennial Acquisition Company and Waramaug Acquisition Corp., collectively as purchasers (as amended from time to time, the “Purchase Agreement”) and (b) if Borrower purchases the Adjacent Parcel pursuant to the Purchase Agreement, the purchase of the Adjacent Parcel.

        The following capitalized terms are defined as set forth below:

        Lender shall provide the Loan to Borrower in an amount equal to the aggregate Purchase Price of the Santa Fe Parcel and, if applicable, the Adjacent Parcel, less Purchaser’s equity contribution to the purchase of such property of Seven Hundred Fifty Thousand and No/100 Dollars ($750,000.00) (the “Equity Contribution”). Any credits against the Purchase Price pursuant to the Purchase Agreement shall not be applied to the Equity Contribution. The Loan will (a) be non-recourse to Borrower, other than with respect to certain customary carve-out provisions as set forth in the Loan Documents (as hereinafter defined), (b) be secured by a deed of trust on the Santa Fe Property and, if and as applicable, the Adjacent Parcel or Parking Easement, which deed of trust shall contain, among other standard provisions, an assignment of leases, a recourse environmental indemnity and a due-on-sale provision, (c) bear interest at a per annum rate of six and three-quarters percent (6.75%), accrued and payable monthly in arrears and computed on an actual/360-day year basis, as more particularly set forth in the Loan Documents, and (d) otherwise be on the terms set forth in the Loan Documents, which shall be on commercially reasonable terms. The maturity date of the Loan will be the date that is two (2) years after the closing date of the Loan, and principal shall be payable at maturity. The closing date for the Loan shall be the closing date of the purchase by Borrower of the Santa Fe Property.

        The Loan shall be evidenced and secured by the following documents (collectively, the “Loan Documents”):

        The obligation of Lender to fund the Loan shall be subject to the fulfillment on or before the closing date of all of the following conditions (the “Loan Closing Conditions”), any or all of which may be waived by Lender in its sole discretion:

2

        If, on or before the closing date for the purchase by Borrower of the Santa Fe Property, the Loan Closing Conditions are not satisfied (or waived by Seller) or the parties hereto are unable to agree on the final form of the Loan Documents (both parties hereby agreeing to act reasonably in the negotiation thereof), then Lender will have no obligation to make the Loan, this commitment letter will be null and void and, except for any obligations that expressly survive termination hereof, neither party hereto will have any further obligations hereunder.

        If Borrower does not obtain the Adjacent Parcel or the Parking Easement at the time of the closing of the Loan, the deed of trust referenced herein will include a provision under which, if Borrower obtains fee title to, a lease of or a parking easement over all or any portion of the Adjacent Parcel after the closing date of the Loan, the deed of trust shall be spread over the interest so acquired.

        The Loan shall be closed on the date of Borrower’s purchase of the Santa Fe Property, provided that Borrower shall have the right, by providing written notice to Lender no later than three (3) Business Days before the scheduled closing date of the Loan, to elect not to accept the Loan from Lender, and upon receipt by Lender of such notice, this loan commitment letter will become null and void and neither party will have any further obligations hereunder except Borrower’s obligation to pay Lender’s legal fees incurred in connection with the drafting and negotiation of the Loan Documents, which obligation shall survive termination or expiration of this commitment letter. If the purchase of the Santa Fe Property is not completed on or before April 30, 2005, this commitment will expire unless otherwise extended by Lender at its option.

        All notices or other communications required or permitted hereunder shall be in writing, and shall be given by hand delivery, or any nationally recognized overnight delivery service with proof of delivery, or by facsimile transmission (provided that such facsimile is confirmed by the sender by expedited delivery service in the manner previously described), sent to the intended addressee at the address set forth below, or to such other address or to the attention of such other person as the addressee will have designated by written notice sent in accordance herewith. Unless changed in accordance with the preceding sentence, the addresses for notices will be as follows:

3

        Lender shall have the right to assign its rights and obligations under this commitment letter to an affiliate of Lender without the consent of Borrower, and upon any such assignment, Mack-Cali Property Trust shall have no further obligations hereunder. Borrower shall have the right to assign its rights and obligations under this commitment letter to one or more entities in which Paul Nussbaum and Steven H. Levin, together or either of them individually, own, directly or indirectly, any portion of the equity interest, provided that The Praedium Fund V, LP or a wholly-owned subsidiary thereof is the controlling investor in such assignee(s) and Borrower provides notice of such assignment to Lender at least five (5) Business Days prior to the scheduled closing date of the Loan, which notice shall include evidence that the assignment complies with the requirements of this sentence.

4

        TIME IS OF THE ESSENCE WITH RESPECT TO ALL TIME PERIODS AND DATES FOR PERFORMANCE SET FORTH IN THIS COMMITMENT LETTER.

        This commitment letter will be construed, performed and enforced in accordance with the laws of the State of Texas.

        This commitment letter shall not become effective until it is executed by all parties hereto and each party has received facsimile or original signatures of each other party. It may be executed in any number of counterparts, all of which taken together will constitute one and the same commitment letter, and the signature page of any counterpart may be removed therefrom and attached to any other counterpart.
