ALIMENTATION COUCHE-TARD SENDS LETTER TO THE BOARD OF DIRECTORS OF CASEY'S
GENERAL STORES

ATD.A, ATD.B / TSX

LAVAL, QC, Sept. 10 /CNW Telbec/ - Alimentation Couche-Tard Inc. ("Couche-Tard") today announced that it has sent the following letter to the Board of Directors of Casey's General Stores, Inc. ("Casey's") (NASDAQ: CASY):

    
    September 10, 2010

    The Board of Directors of Casey's General Stores, Inc.
    Casey's General Stores, Inc.
    One Convenience Blvd.
    Ankeny, Iowa 50021

    To the Board of Directors of Casey's General Stores:

    We read with interest that you have authorized discussions with 7-Eleven,
    Inc.

    We are disappointed that, instead of engaging in discussions with us with
    respect to our all-cash, fully financed tender offer for Casey's General
    Stores, Inc. ("Casey's"), including our recently increased offer price of
    $38.50 per share, over the last five months, you have continually created
    obstacles that are designed not only to impede our offer, but to impede a
    sale of Casey's to any party. On September 7, 2010, with only two weeks
    remaining before the 2010 Annual Meeting of Shareholders of Casey's (the
    "Annual Meeting") and only days after completion of the self-tender by
    Casey's, you announced that you have authorized discussions with a third-
    party to explore a transaction based solely on a preliminary proposal
    that was first communicated to you in a telephone call on September 2,
    2010. This appears to be an attempt to distract your shareholders, in the
    midst of a proxy contest, from considering our fully financed offer.

    Since you have begun the process of exploring a sale transaction
    involving Casey's, we fully expect that you will afford us the same
    opportunity to participate in the process. Our senior management team and
    our legal and financial advisors have been and remain ready to meet with
    you and your representatives to negotiate a transaction that benefits
    your shareholders. We are prepared to proceed expeditiously.

    Your shareholders will benefit if all interested bidders are granted
    equal access to the process and an opportunity to submit offers derived
    from that process. In our case, our offer has been made public since
    April 2010, and we have increased our offer price to $38.50 per share. If
    we are granted access to a fair process and have the opportunity to
    conduct a confirmatory due diligence review of Casey's, we would be
    willing to consider further increasing our offer. Should Casey's decline
    to conduct a fair process, your shareholders would be deprived of
    additional value that we may have been willing to offer.

    To that end, we suggest that you delay the Annual Meeting, currently
    scheduled to be held on September 23, 2010, for two to three weeks so
    that you can complete a full and fair sale process and report the results
    of such process to your shareholders prior to the Annual Meeting. In this
    manner, your shareholders, the true owners of Casey's, will have the
    opportunity to decide the future of Casey's for themselves with the
    benefit of complete information.

    We trust that you will act in the best interest of your shareholders and
    proceed with a full and fair sale process in a manner consistent with the
    above. We look forward to a timely and favorable response.

    Sincerely,

    /s/ Alain Bouchard

    Alain Bouchard

    President and Chief Executive Officer
