            (xxx) AN IMPORTANT LETTER TO ALL CASEY'S SHAREHOLDERS (xxx)

      COUCHE-TARD'S IMPROVED $38.50 PER SHARE OFFER DELIVERS IMMEDIATE CASH
                      VALUE FOR YOUR INVESTMENT IN CASEY'S

                    VOTE THE ENCLOSED BLUE PROXY CARD TODAY
                                      ----

    Dear Casey's General Stores Shareholder:

    On September 1, 2010, Alimentation Couche-Tard ("Couche-Tard") announced
    an improved offer to acquire all of the outstanding shares of common
    stock of Casey's General Stores, Inc. ("Casey's") for $38.50 per share in
    cash. We also announced that Couche-Tard secured financing to consummate
    the transaction, providing the Casey's shareholders with increased
    certainty of closing. We strongly believe that Couche-Tard's all-cash,
    fully-financed premium offer is the most attractive strategic alternative
    available to shareholders of Casey's, and delivers immediate cash value
    superior to what Casey's can deliver continuing as a standalone company.

    With the September 23rd Annual Meeting of Shareholders of Casey's only
    weeks away, we are writing for your support to elect to your Board eight
    new, independent and qualified directors, who are committed to fairly
    considering Couche-Tard's all-cash premium offer. We urge you to vote
    TODAY by telephone, by Internet or by signing, dating and returning the
    enclosed BLUE proxy card in the postage-paid envelope provided.

        COUCHE-TARD'S IMPROVED, FULLY-FINANCED $38.50 PER SHARE ALL-CASH
              OFFER MAXIMIZES VALUE FOR YOUR INVESTMENT IN CASEY'S

    In raising our offer to $38.50 per share in cash, we have taken into
    account the views of the Casey's shareholders and our goal of completing
    a transaction that makes compelling strategic sense for both companies.
    In the recent self-tender offer by Casey's, the Casey's shareholders made
    their views on the value of Casey's clear. The fact that a majority of
    the then-outstanding shares of Casey's were tendered at $38.00 per share
    demonstrates that our revised offer to acquire 100% of the outstanding
    shares of Casey's for $38.50 per share in cash is compelling. Consider
    the premium of Couche-Tard's offer:

      - A premium of 32% over the one-year average closing share price of
        common stock of Casey's as of April 8, 2010; and
      - A premium of 17% to the all-time and 52-week high trading price of
        common stock of Casey's prior to our announcement.

    Couche-Tard's revised offer also implies a last twelve months (as of
    April 30, 2010) EBITDA(1) multiple of 7.5x and a price of $1.3 million
    per store, which compares favorably to corresponding metrics of publicly-
    traded companies and precedent transactions in the convenience store
    industry.

        SECURED FINANCING UNDERSCORES SERIOUSNESS OF OFFER AND COMMITMENT
                         TO MAKING COMBINATION A REALITY

    In addition, we announced that Couche-Tard secured up to $1.5 billion in
    financing, which, together with Couche-Tard's existing credit facilities
    and cash on hand, will be used to acquire all of the outstanding shares
    of common stock of Casey's. As we have said all along, Couche-Tard is
    making its offer from a position of financial strength. Our new financing
    agreement underscores the seriousness of our offer and our deep
    commitment to making a combination with Casey's a reality.

     YOUR BOARD OF DIRECTORS HAS TAKEN STEPS TO PREVENT CASEY'S SHAREHOLDERS
           FROM REALIZING FULL AND IMMEDIATE VALUE FOR YOUR INVESTMENT

    Despite our repeated efforts since October 2009 to begin a dialogue with
    Casey's and its advisors regarding our offer, and against the demands of
    a number of shareholders of Casey's, your Board has repeatedly refused to
    meet with Couche-Tard or even discuss our offer. Even though Casey's has
    had since October 2009 to explore alternatives to Couche-Tard's offer,
    the fact remains that no other acquiror has provided a higher price for
    Casey's, and the Casey's Board and management have not presented any
    alternative that provides value greater to the Casey's shareholders than
    Couche-Tard's offer.

    Rather, Casey's undertook a leveraged recapitalization plan that
    temporarily manipulates the price of the common stock of Casey's and is a
    pretext for installing a coercive financing arrangement that includes a
    costly and unusual "poison put" feature. By agreeing to this poison put,
    assuming such poison put is legally enforceable, your Board will have
    effectively transferred approximately $100 million of shareholder value
    (based on current treasury rates) from the Casey's shareholders to the
    Casey's noteholders in the event any buyer were to acquire Casey's.

    This highly unusual penalty is a coercive, self-serving ploy by the
    Casey's Board and management to take away from shareholders - the true
    owners of Casey's - the decision regarding the future of Casey's, while
    unduly favoring the Casey's noteholders at your expense. Consider the
    facts of the recent leveraged recapitalization plan of Casey's:

      - If enforceable, the "poison put" feature of the notes issued by
        Casey's to finance its recapitalization makes it approximately
        $100 million more expensive to acquire Casey's (based on current
        treasury rates), which equates to approximately $2.65 per share
        (after giving effect to the Casey's recapitalization).
        - This is an 18% premium to the Casey's noteholders, which represents
          approximately 7% of the current equity value of Casey's (pro forma
          for the self tender) based on current stock prices.
      - Couche-Tard's financing is at a lower interest rate than the Casey's
        recapitalization plan (even after the cost of converting from a
        floating to a fixed interest rate) without ANY penalty for a change
        in control.
      - Typically, debt financing used by companies like Casey's provide for
        change of control premiums in the range of 1% to 3% of the
        outstanding amount of the debt.
      - Casey's repurchased only approximately 25% of its shares whereas
        Couche-Tard is offering immediate cash value for 100% of the
        outstanding shares of common stock of Casey's at a price higher than
        what Casey's paid in the recapitalization.

    Couche-Tard believes that the Casey's leveraged recapitalization plan is
    a thinly concealed effort by the Casey's Board and management to entrench
    themselves. If the Casey's Board and management truly believed a
    recapitalization would create value for shareholders, at almost any time
    in the past, Casey's could have repurchased a significant amount of its
    shares with financing on terms far more favorable to Casey's than the
    terms that Casey's accepted in connection with its recent self-tender.
    Quite conveniently, and only after Couche-Tard made its offer to acquire
    Casey's and after all other efforts by Casey's to create shareholder
    value superior to Couche-Tard's offer had failed, did your Board and
    management claim to see value creation through the repurchase of its
    common stock. Couche-Tard believes the Casey's leveraged recapitalization
    plan is nothing more than a last-ditch effort by your Board and
    management to engineer a temporary increase in the stock price of
    Casey's, discourage any sale of Casey's, and distract the Casey's
    shareholders from Couche-Tard's premium all-cash offer - the only true
    value-maximizing alternative for Casey's.

    In contrast to assertions made by Casey's, Couche-Tard obtained up to
    $1.5 billion in financing on terms significantly more favorable than the
    terms of the notes issued by Casey's to finance its leveraged
    recapitalization plan, despite Couche-Tard's higher leverage and the
    leverage of a combined Couche-Tard and Casey's on a pro forma basis. Also
    in contrast to the financing obtained by Casey's, Couche-Tard's financing
    does not provide for a make-whole payment at the expense of shareholders
    in any event.

          THE CASEY'S BOARD AND MANAGEMENT ARE NOT SERVING SHAREHOLDERS'
                                  BEST INTERESTS

    Rather than entering into discussions with Couche-Tard with the goal of
    seeking to maximize value for the Casey's shareholders, we believe that
    the Casey's Board and management are attempting to protect their own jobs
    through a series of maneuvers designed to prevent a sale of Casey's. Not
    only have the Casey's Board and management continued to refuse to
    negotiate with Couche-Tard or allow us to conduct any due diligence, they
    have also taken actions to obstruct our all-cash premium offer.
    Specifically, in addition to the leveraged recapitalization plan
    discussed above, your Board and management commenced expensive and
    meritless litigation against Couche-Tard, adopted a poison pill and put
    in place lucrative golden parachute arrangements for executives of
    Casey's.

    Ask yourself: Why has your Board and management, who collectively own
    less than 1% of stock of Casey's, made every effort to prevent you from
    realizing full and immediate value through Couche-Tard's all-cash premium
    offer?

    We believe that the Casey's Board and management team do not hold the
    same vested interest as their shareholders, and are not acting in the
    best interest of ALL shareholders of Casey's.

                    ELECT NEW DIRECTORS WHO ARE COMMITTED TO
              MAXIMIZING THE VALUE OF YOUR INVESTMENT IN CASEY'S -
                    VOTE THE ENCLOSED BLUE PROXY CARD TODAY
                                      ----            -----

    Couche-Tard's independent nominees bring experience, deep insight and
    responsibility and are committed to maximizing value for all the Casey's
    shareholders. We are confident that, if elected to the Casey's Board,
    they will exercise independent judgment in considering Couche-Tard's
    premium offer. We urge you to vote TODAY by telephone, by Internet or by
    signing, dating and returning the enclosed BLUE proxy card in the
    postage-paid envelope provided.

    It's your investment. It's your company. It's up to you to decide.

    Thank you for your support.

    Sincerely,

    /s/ Alain Bouchard

    Alain Bouchard
    President and Chief Executive Officer
