(formerly known as Mark Centers Trust) (the "Trust"), a Maryland real estate investment trust, whose principal executive offices are located at 805 Third Avenue, 9th Floor, New York, New York 10022. Except as specifically provided herein, this Amendment does not modify any of the information previously reported on Schedule 13D. Item 4. Purpose of Transaction Item 4 is amended and restated in its entirety as set forth below. The purpose of the acquisition of the shares of Common Stock by Five Arrows reported herein is for investment. The purchase of the shares of Common Stock reported herein was effected on the New York Stock Exchange. Five Arrows intends to review its holdings with respect to the Trust on a continuous basis. Depending on Five Arrows' evaluation of the Trust's business and prospects, and upon future developments (including, but not limited to, market prices of the shares of Common Stock and availability and alternative uses of funds; as well as conditions in the securities markets and general economic and industry conditions), Five Arrows may acquire other securities of the Trust; sell all or a portion of its shares of Common Stock or other securities of the Trust, now owned or hereafter acquired. Other than as described above, Five Arrows has no present plans or proposals which relate to, or would result in, any of the matters enumerated in paragraphs (b) through (j), inclusive, of Item 4 of Schedule 13D. Five Arrows may, at any time and from time to time, review or reconsider its position with respect to the Trust, and formulate plans or proposals with respect to any such matters. Item 5. Interest in Securities of the Issuer Item 5 is amended and restated in its entirety as set forth below. a) As of the close of business on April 18, 2002, Five Arrows owned, within the meaning of Rule 13d-3 under the Exchange Act, 2,275,167 shares of Common Stock, including those shares originally reported in the Group Schedule 13D. Five Arrows beneficially owns 9.2% of the issued and outstanding shares of Common Stock (based on 24,700,328 shares of Common Stock outstanding as of April 1, 2002 as reported in the Definitive Proxy Statement of the Trust filed on April 16, 2002). Rothschild, as sole managing member of Five Arrows, may be deemed the beneficial owner of the 2,275,167 shares of Common Stock held by Five Arrows. (b) Five Arrows has the sole power to vote and dispose of the shares of Common Stock owned by it reported herein, which power may be exercised by Rothschild. (c) On February 21, 2002, the Trust purchased 900,000 shares of Common Stock (representing 3.6% of the shares of Common Stock outstanding) from Five Arrows at a price of $6.05 for a total of $5,445,000. Such shares had been tendered by Five Arrows into the Trust's tender offer described in the Offer to Purchase, dated December 20, 2001 ("Offer to Purchase"), and related Letter of Transmittal (the "Offer"). On April 11, 2002, Five Arrows, in open market sales, sold 15,000 shares of Common Stock (representing 0.1% of the shares of Common Stock outstanding) at an average per share price of $7.00 for a total of $105,000. (d) Not applicable. (e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer Item 6 is amended and restated in its entirety as set forth below.
