RECITALS

        WHEREAS, on February 26, 2002, Roath and the Company entered into a
Separation Agreement (the "Separation Agreement") that provided, among other
things, for the treatment of the option to purchase shares of Longs Drug Stores
Corporation common stock then held by Roath; and

        WHEREAS, at the time of entry into such Separation Agreement, both Roath
and the Company were mistaken about the terms of the option; and

        WHEREAS, to remedy such mutual mistake, Roath and the Company desire to
enter into this Amendment, to revise the treatment of the option in such
Separation Agreement.

        NOW, THEREFORE, in consideration of the mutual promises, covenants and
representations set forth in the Separation Agreement and for other good and
valuable consideration, the parties agree as follows:

        1.    Defined Terms.    Capitalized terms used in this Amendment but not
defined in this Amendment have the meaning given them in the Separation
Agreement.

        2.    Amendment.    Section 3(c) of the Separation Agreement is hereby
deleted in its entirety and the following substituted therefor:

        "(c) Roath's resignation shall be deemed "Normal Retirement' for
purposes of his option to purchase 30,000 shares of Longs Drug Stores
Corporation common stock under the 1995 Long-Term Incentive Plan, which option
was granted to him on November 17, 2000."

        3.    Full Force and Effect.    Except as expressly amended hereby, the
Separation Agreement shall remain in full force and effect.

        4.    Counterparts.    This Amendment may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

        5.    Governing Law.    This Amendment is deemed to have been made and
entered into in the State of California and shall in all respects be
interpreted, enforced and governed under the laws of the State of California.
