On August 12, 2008, Longs Drug Stores Corporation, a Maryland corporation (the “Company”), CVS Caremark Corporation, a Delaware corporation (“CVS”), and Blue MergerSub Corp., an indirect wholly owned subsidiary of CVS (“Purchaser”), entered into an Agreement and Plan of Merger (the “Merger Agreement”).

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Purchaser commenced a tender offer to purchase all outstanding shares of common stock, par value $0.50 per share (“Shares”), of the Company for $71.50 per Share, net to the seller in cash, without interest (the “Offer Price”), upon the terms and subject to the conditions set forth in the Offer to Purchase dated August 18, 2008 and in the related Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the “Offer”).

The initial offering period of the Offer expired at 6:00 p.m., New York City time, on Friday, October 17, 2008. A total of approximately 27,749,072 Shares (including 3,144,720 Shares tendered by notice of guaranteed delivery) were validly tendered and not withdrawn as of the expiration date of the initial offering period of the Offer, representing approximately 76.51% of the outstanding Shares. Purchaser has accepted all Shares that were validly tendered and not withdrawn prior to expiration of the Offer for payment pursuant to the terms of the Offer.

Based on the Offer Price and the number of outstanding Shares tendered and accepted for purchase, the value of the Shares purchased by Purchaser as of October 20, 2008 in connection with the Offer is approximately $1.984 billion. The amount of consideration and source of funds used by Purchaser to acquire the Company’s outstanding Shares in the initial offering period of the Offer is described in Item 10 of Purchaser’s Schedule TO and related Offer to Purchase, which description is incorporated herein by reference.

CVS and Purchaser announced a subsequent offering period commencing on Monday, October 20, 2008 and expiring on Tuesday, October 28, 2008 at 6:00 p.m., New York City time. During the subsequent offering period, Purchaser will accept for payment and promptly pay for Shares as they are tendered. Shareholders who tender Shares during such period will be paid the Offer Price. Shares tendered during the subsequent offering period may not be withdrawn. Purchaser may extend the subsequent offering period. If the subsequent offering period is extended, Purchaser will notify the depositary for the offer and issue a press release prior to 9:00 a.m. New York City time on the first business day following the date the subsequent offering period was scheduled to expire.

Pursuant to the Merger Agreement, Purchaser will merge with and into Longs (the “Merger”), with Longs surviving the Merger as an indirect wholly owned subsidiary of CVS. At the effective time of the Merger, any remaining outstanding Shares not tendered in the Offer, other than Shares owned by CVS or any direct or indirect wholly owned subsidiary of CVS or Longs, will be acquired for cash at the Offer Price. The Merger is expected to occur by the end of October 2008. On October 20, 2008, CVS Caremark Corporation issued a press release announcing the results of the initial offering period and the commencement of the subsequent offering period. The press release is attached hereto as Exhibit 99.1.
