SEARS, ROEBUCK AND CO. AND KMART HOLDING CORP.
CONFIRM ELECTION DEADLINE IN CONNECTION WITH PROPOSED MERGER

Troy, MI, and Hoffman Estates, IL, March 17, 2005 – Kmart Holding Corporation (“Kmart”) (NASDAQ: KMRT) and Sears, Roebuck and Co. (“Sears”) (NYSE: S) confirmed today that the deadline for Sears shareholders of record to make merger consideration elections in connection with the proposed merger of Kmart and Sears is 5:00 p.m., Eastern Time, on March 24, 2005. Sears shareholders who hold their shares in “street name,” through the Sears associate stock purchase plan, or in certain Sears retirement plans may have an election deadline earlier than March 24, 2005. Such shareholders should carefully review any materials they received from their broker or the relevant plan trustee or administrator to determine the election deadline applicable to them.

Sears shareholders of record wishing to make an election regarding the consideration they would like to receive for their Sears shares must deliver to EquiServe Trust Company, N.A., the exchange agent, properly completed Election Forms, together with their stock certificates or properly completed notices of guaranteed delivery, by 5:00 P.M., Eastern Time, on Thursday, March 24, 2005, the election deadline.

Sears shareholders may elect cash, shares of common stock of Sears Holdings Corporation, the new holding company created to facilitate the merger of Kmart and Sears, or a combination of the two for their Sears shares. All elections are subject to the proration procedures provided

 2

in the merger agreement designed to ensure that in the aggregate 55 percent of Sears shares will be converted into the right to receive 0.5 of a share of Sears Holdings common stock per share and 45 percent of Sears shares will be converted into the right to receive a cash consideration of $50.00 per share, without interest, upon the mergers’ completion. As a result, a Sears shareholder may not receive the exact form of consideration elected, and the ability of a Sears shareholder to receive the form of consideration elected will depend on the elections made by other Sears shareholders.

All of the documents necessary to make merger consideration elections were previously mailed to Sears shareholders of record as of January 26, 2005. Sears shareholders may obtain additional copies of the election documents by contacting D.F. King & Co., Inc. at (800) 549-6650.

A more complete description of the merger consideration and the adjustment and proration mechanisms applicable to elections is contained in the election materials mailed to Sears shareholders and the joint proxy statement/prospectus dated February 18, 2005, both of which Sears shareholders are urged to read carefully and in their entirety.

Kmart and Sears expect to publicly announce the preliminary proration calculation on Monday, March 28, 2005. The final election results, including the consideration to be received by Sears shareholders who elect cash and who elect stock, will be announced as soon as practicable thereafter.

The proposed merger remains subject to the satisfaction of closing conditions, including Kmart and Sears shareholder approval. As previously announced, a meeting date of March 24, 2005, has been established for meetings of Kmart and Sears shareholders to vote on the merger agreement.

Sears and Kmart shareholders are also reminded that holders of record of Sears common stock and Kmart common stock, respectively, as of the close of business on January 26, 2005 are entitled to vote on the proposed merger and may vote by telephone, the Internet or by mail, as explained in detail in the joint proxy statement/prospectus dated February 18, 2005.
