Ms. Brower resigned from her position as General Counsel, Secretary and Executive Vice President of both the Operating Trust and the Operating Trust’s sole trustee, Tishman Speyer Archstone-Smith Multifamily Series I Trust, as successor by merger to Archstone-Smith Trust (“ASN”). Upon her retirement, Ms. Brower is entitled to receive the amounts payable upon a termination of employment pursuant to Section 5 of the change in control agreement entered into between Ms. Brower, the Operating Trust, and ASN, dated as of August 12, 2002, as amended on May 28, 2007 (the “Agreement”). The terms of the Agreement and estimated payments to Ms. Brower pursuant to the Agreement were previously disclosed in ASN’s definitive proxy statement regarding the merger, which was originally filed with the Securities and Exchange Commission (the “Commission”) on July 13, 2007, and in the Operating Trust’s registration statement on Form S-4 (File No. 333-144717), originally filed with the Commission on July 19, 2007. The Operating Trust will pay these amounts to Ms. Brower, which include a lump sum cash amount equal to two times Ms. Brower’s then-current annual salary plus the greater of Ms. Brower’s 2007 target bonus assuming the highest applicable performance targets have been met or the cash bonus earned by Ms. Brower for 2006, a lump sum cash amount equal to Ms. Brower’s 2007 target bonus, medical insurance, life insurance coverage and death benefits during the next two years, up to $15,000 in outplacement services, and gross-up payments for “excess parachute payment” excise taxes.

The Operating Trust is searching for a replacement for Ms. Brower. Ms. Brower will be available as a consultant and advisor to the Operating Trust upon our request. Ms. Brower will be paid $550 per hour and will be guaranteed a minimum of 15 hours per week.
