Exhibit 99 RATE HEDGE AGREEMENT This Agreement is made the 18th of May, 1994, between United Dominion Realty Trust, a Virginia corporation (the "Customer"), and Goldman, Sachs & Co., a New York limited partnership ("Goldman Sachs"). WHEREAS, the Customer intends to issue, within the term of this Agreement, its debt Securities ("Debt"), with a maturity of approximately 1O years, and wishes to enter into a notional principal contract in the amount of $75MM to hedge itself against the risk that the general level of interest rates for securities with similar maturities might rise from their current level during the term of this Agreement; and WHEREAS, the Customer intends this Agreement to qualify as a hedging transaction within the meaning of Section 1256(e)(2) of the Internal Revenue Code of 1986 as amended: NOW, THEREFORE, THIS AGREEMENT WITNESSETH: 1.

For the purposes of this Agreement, the following terms shall have the meanings indicated: (a) "Adjustment Price": the number determined in accordance with the formula set forth in paragraph 3 of Schedule A hereto. (b) "Agreement Date": the date set forth in the first paragraph hereof. (c) "Alternate Takedown Price": the price (stated in percent) determined in accordance with Section 2(c) hereof. (d) "Base Treasury Price": the price, expressed in percent, set forth in paragraph 1 of Schedule A hereto. (e) "Base Treasury Securities": the securities set forth in paragraph 2 of Schedule A hereto. (f) "Business Day": each Monday, Tuesday, Wednesday, Thursday, and Friday which is not a day on which Goldman Sachs, the Customer, or the Federal Reserve Bank of New York are closed or banking institutions in the State of New York are authorized or obligated by law or executive order to close. (g) "Determination Date": the date on which the Takedown Price shall be accepted, or deemed to be accepted, by the Customer. (h) "Price Differential": the amount obtained by multiplying (i) the difference (stated in percent) between the Base Treasury Price and the Takedown Price, times (ii) the Base Treasury Securities. (i) "Readjustment Factor": the number determined in accordance with the formula set forth in paragraph 3(b) of Schedule A hereto. (j) "Takedown Price": the price (stated in percent) determined in accordance with Sections 2 and 3 hereof and Schedule A hereto. (k) "Termination Date": the date set forth in paragraph 4 of Schedule A hereto. 2. Selection of a Takedown Price. (a) On any Business Day, between the hours of 9:00 a.m. and 3:00 p.m. (New York City time), the Customer may request Goldman Sachs to quote a Takedown Price. Within one hour of receipt by Goldman Sachs of such a request, Goldman Sachs shall quote an unadjusted Takedown Price to the Customer; provided, however, that Goldman Sachs may, but shall not be obligated to, quote a Takedown Price (i) at any time within one hour before an expected announcement of money supply data or other economic statistics by the government of the United States of America or any agency thereof, (ii) if an event (including an announcement of money supply data or other economic statistics) shall have occurred that would, in the judgment of Goldman Sachs, materially affect the quotation of a Takedown Price, or (iii) if in the opinion of Goldman Sachs there does not at such time exist an active dealer market for the Base Treasury Securities. Upon receipt by the Customer of such quotation subject to paragraph (c) of this Section, the Customer shall immediately accept or reject such unadjusted Takedown Price. If the Customer shall not have accepted such unadjusted Takedown Price, the Customer shall be deemed to have rejected such unadjusted Takedown Price. (b) If the Customer shall not have accepted a quoted Takedown Price, and Goldman Sachs and the Customer shall not be deemed to have accepted an Alternate Takedown Price, prior to 11:30 a.m. (New York City time) on the Termination Date, Goldman Sachs shall quote an unadjusted Takedown Price to the Customer at or prior to 4:00 p.m. (New York City time), and except as provided in paragraph (c) of this Section the Customer shall be deemed to have accepted such Takedown Price. (c) Notwithstanding paragraphs (a) and (b) of this Section, if, following the quotation by Goldman Sachs to the Customer of an unadjusted Takedown Price pursuant to either such paragraph, the Customer immediately rejects such unadjusted Takedown Price and notifies Goldman Sachs that the Customer has received from another leading U.S. Government securities dealer a firm bona fide offer to sell the Base Treasury Securities to the Customer at a price (stated in percent) (an "Alternate Takedown Price"), lower than the price quoted by Goldman Sachs, then Goldman Sachs shall immediately quote a new unadjusted Takedown Price (which may be the same as its previously quoted unadjusted Takedown Price) to the Customer, and the Customer shall immediately accept or reject such new unadjusted Takedown Price. If the Customer does not immediately accept such new unadjusted Takedown Price, the Customer and Goldman Sachs shall be deemed to have accepted the Alternate Takedown Price, provided, that in addition the Customer shall be deemed to have agreed to sell to Goldman Sachs the Base Treasury Securities at the Alternate Takedown Price. The settlement date for such sale to Goldman Sachs shall be the next settlement date that, in accordance with customary trade practices, would apply if the Base Treasury Securities had been bought back on the Determination Date. The method of settlement shall be the method that, in accordance with customary trade practices, is employed with respect to the Base Treasury Securities. 3. Settlement Price. Upon acceptance pursuant to Section 2 hereof of the unadjusted Takedown Price by the Customer, or of the Alternate Takedown Price by Goldman Sachs, the following calculations and payments shall be made: (a) The Takedown Price or the Alternate Takedown Price (as the case may be) established pursuant to Section 2 above shall be adjusted (up or down) by adding thereto the Adjustment Price (positive or negative) determined in accordance with paragraph 3(a) of Schedule A hereto, such Adjustment Price to be modified by the Readjustment Factor determined pursuant to paragraph 3(b) of Schedule A if the Takedown Price (or Alternate Takedown Price) is determined on a date prior to the Termination Date. The Takedown Price or Alternate Takedown Price, as adjusted, shall be the "Takedown Price" for purposes of determining the settlement price below. (b) If the Takedown Price exceeds the Base Treasury Price, the Customer shall owe Goldman Sachs the amount of the Price Differential. If the Takedown Price is less than the Base Treasury Price, Goldman Sachs shall owe the amount of the Price Differential to the Customer. (c) The payment of the Price Differential shall be made in immediately available federal funds by wire transfer on the Business Day immediately following the Determination Date to the appropriate account of the receiving party specified in paragraph 5 or 6 of Schedule A hereto. (d) If the party required to pay the Price Differential hereunder fails to do so in a timely manner, interest on such amount shall accrue from and including the Determination Date through the date that such amount plus interest is paid in full at an annual rate equal to 2% above the prime brokers' loan rate. The prime brokers' loan rate will be determined by Goldman Sachs for this purpose, in Goldman Sachs' sole discretion, in accordance with prevailing money market conditions. It is understood that in making such determination, Goldman Sachs will consider, among other things, the rates quoted for brokers' loans by one or more New York banks which are members of the New York Clearing House Association. Interest shall be computed daily, using a 360 day base year. 4. Transfer.
