PROMISSORY NOTE --------------- $5,000,000 New York, New York October 31, 1994 FOR VALUE RECEIVED 0&Y Equity Company, L.P. and O&Y (U.S.) Development Company, L.P., each a Delaware limited partnership (individually and together hereinafter called "Maker"), hereby promise to pay to the order of JMB/125 Broad Building Associates, L.P., an Illinois limited partnership (hereinafter called "Payee"), at 900 North Michigan Avenue, Chicago, Illinois 60611, or at such other place as Payee or any holder of this Note may from time to time designate, the principal sum of Five Million Dollars ($5,000,000), together with interest at the Interest Rate (as hereinafter defined), in lawful money of the United States, on the Maturity Date (as hereinafter defined). Interest shall be computed on the basis of a 365-day or 366-day year, as the case may be. The following capitalized terms are defined as follows for purposes of this Note: "Interest Rate" shall mean 4.5% per annum simple interest; provided however, that if O&Y Equity Company, L.P. ("Equityco") executes and delivers to Canadian Imperial Bank of Commerce ("CIBC") a promissory note (which note, as it may be amended from time to time, and/or any separate standstill, forbearance or similar agreement (a "Standstill Agreement") relating thereto, is herein referred to as the "CIBC Note") in settlement of Equityco's obligations to CIBC under two Guarantee Agreements dated as of June 25, 1987 given by Equityco to CIBC in connection with the mortgage loan made by CIBC to 125 Broad Street Company, then the "Interest Rate" shall thereafter be equal to the greater of 4.5% per annum simple interest or the interest rate under the CIBC Note. "Maturity Date" shall mean October 31, 1999; provided, however, that if the CIBC Note is executed and delivered, then the "Maturity Date" shall be the earlier of (i) maturity date under the CIBC Note or (ii) December 31, 1999. Maker may, at its option, at any time and from time to time, prepay all or any part of (i) the interest accrued and unpaid under this Note ("Unpaid Interest"), or (ii) the unpaid principal balance of this Note ("Unpaid Interest"), together with all Unpaid Interest accrued thereon. Each such partial prepayment shall be applied first to Unpaid Interest and then to Unpaid Principal. If the CIBC Note is executed and delivered, then Maker shall make a mandatory prepayment (a "Required Prepayment") on account of Unpaid Interest and/or Unpaid Principal on each date on which a payment of interest and/or principal is paid under the CIBC Note (a "CIBC Payment"), which Required Prepayment shall consist of and be in an amount equal to the sum of (i) the Unpaid Interest multiplied by a percentage that is equal to the percentage that such CIBC Payment of accrued and unpaid interest constitutes of the total accrued and unpaid interest on the CIBC Note on each such date plus (ii) the Unpaid Principal multiplied by a percentage that is equal to the percentage that such CIBC Payment of principal constitutes of the total outstanding principal of the CIBC Note on each such date. For purposes of the foregoing, a CIBC Payment shall be deemed to have been made at the time it was to have been due and payable if the holder of the CIBC Note agrees (other that in a Standstill Agreement Delivered at the time the CIBC Note is first delivered) to a deferral of such CIBC Payment (a "CIBC Deferral"), unless Maker gives to Payee, on or before such date, consideration equivalent and proportionate to the consideration (if any) given to the holder of the CIBC Note (the "CIBC Consideration") to obtain such deferral (it being understood that such consideration to be given to Payee shall be in an amount that bears the same proportion to the deferred Required Prepayment as the CIBC Consideration bears to the deferred CIBC Payment). Maker shall deliver to Payee (i) copies of all financial statements and other informational materials that Maker delivers to the holder of the CIBC Note pursuant thereto, at the same times as such deliveries are made to such holder, and (ii) copies of the CIBC Note (and any amendments thereto and any separate Standstill Agreement relating thereto) and notice of any CIBC Deferral promptly after delivery of any thereof. If the CIBC Note is not executed and delivered, then for purposes hereof, all references herein to the CIBC Note shall refer instead to the note first executed and delivered after the date hereof by Maker, or either of the parties comprising Maker, to a commercial bank (or, at Payee's option, another entity that is not an "Affiliate" of Maker (as such quoted term is defined in the Draft Plan hereinafter referred to)), to evidence an unsecured recourse claim (including deficiency claim that is subsequently liquidated as unsecured) against such party that arose from an extension of credit or other loan accommodation (as such note may be amended from time to time, together with any separate Standstill Agreement relating thereto). By its acceptance of this Note, Payee agrees that it will not oppose, directly or indirectly, a plan of reorganization of Maker (or either party comprising Maker) under Chapter 11 of the Bankruptcy Code (as defined in the Draft Plan) which provides that the reorganized debtor to its successor will emerge from Chapter 11 with (i) the obligation to pay the Debt in full over a term and in a manner that is at least as favorable to Payee as the terms hereof, and (ii) Maker's obligations under the release and Indemnity dated this date from Maker to Payee. 2 Payee may, at its option, declare the entire Unpaid Principal and all Unpaid Interest (the "Debt") to be immediately due and payable upon (i) the commencement by Maker of a case under the Bankruptcy Code, or under any other applicable federal or state bankruptcy law or other similar law (which, is in the case of an involuntary proceeding, is not contested or is not set aside within 120 days); (ii) the appointment of a trustee or receiver of all or a substantial part of the property then owned by Maker; (iii) an assignment for the benefit of creditors by Maker; or (iv) the failure by Maker to make any Required Prepayment within ten business days after the due date therefor. After maturity (by acceleration or otherwise), and both before and after judgment, the unpaid principal balance of this Note, and interest accrued thereon, shall bear interest at an annual rate equal to (i) the greater of 7.5% or the "Default Rate" under the CIBC Note (if entered into), or (ii) the maximum rate permitted by law, whichever is less. Such interest shall be computed on the basis of a 365-day or 366-day year, as the case may be. No remedy of Payee if exclusive of any other remedy provided herein or at law, and all remedies available to Payee shall be cumulative. Maker hereby waives diligence, demand, presentment, protest and notice of any kind, and assents to extensions of the time of payment, releases, or forbearance or other indulgence, without notice. This Note may note be changed, modified or terminated orally, but only by an agreement in writing signed by the party to be charged. The obligations of the parties constituting Maker hereunder shall be joint and several. Maker represents and warrants to Payee that the CIBC Note referred to herein is the same as the "Equityco Note" referred to in the draft Plan of Reorganization for 125 Broad Street Company, a copy of which has been delivered to Payee (the "Draft Plan"). 3 IN WITNESS WHEREOF, Maker has executed this Note as of the date first above written.
