    ATD.A, ATD.B / TSX

LAVAL, QC, Sept. 1 /PRNewswire-FirstCall/ - Alimentation Couche-Tard Inc. ("Couche-Tard") today announced that it has increased its tender offer, through an indirect wholly owned subsidiary, to acquire all of the outstanding shares of common stock of Casey's General Stores, Inc. ("Casey's") (NASDAQ: CASY) to $38.50 per share in cash. The revised offer implies a total enterprise value of approximately $2.0 billion on a fully diluted basis, including net debt of Casey's of approximately $528 million.

Couche-Tard's increased all-cash offer of $38.50 per share of Casey's is $0.50 per share higher than the price at which a majority of the then outstanding shares of Casey's were tendered in Casey's recent self-tender. It represents a 32% premium over the one-year average closing share price of Casey's as of April 8, 2010 (the last trading day prior to the public disclosure of Couche-Tard's proposal), a 26% premium over the 90-calendar day average closing share price of Casey's as of April 8, 2010, and a 22% premium over the closing price of $31.59 per share of Casey's on April 8, 2010. Couche-Tard's increased offer also represents a 17% premium to the all-time and 52-week high trading price of common stock of Casey's prior to April 8, 2010.

Alain Bouchard, President and Chief Executive Officer of Couche-Tard commented, "In raising our offer, 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 Casey's self-tender offer, the shareholders of Casey's made clear their views on the value of Casey's. 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. We believe that our revised offer is the most attractive strategic alternative available to the Casey's shareholders, and delivers immediate cash value superior to what Casey's can deliver continuing as a standalone company. We remain ready, willing and able to complete a transaction with Casey's expeditiously and urge the Casey's Board of Directors to begin discussions with Couche-Tard immediately to maximize value for the Casey's shareholders and make this combination a reality."

Couche-Tard's Acquisition Financing

Couche-Tard also today announced that it entered into a credit agreement with a consortium of Canadian and international financial institutions led by The Bank of Nova Scotia, HSBC Bank Canada, Caisse de dépôt et placement du Québec and Rabobank Nederland, Canadian Branch, pursuant to which such institutions have agreed to provide up to $1.5 billion in funds pursuant to a four year unsecured term loan facility, subject to the terms and conditions set forth in the credit agreement. The term loan facility, together with Couche-Tard's existing credit facilities and cash on hand, will be used to finance Couche-Tard's tender offer to acquire all of the outstanding shares of common stock of Casey's.

The initial interest rate on Couche-Tard's new term loan facility is expected to be LIBOR plus 300 basis points or the US Base Rate plus 175 basis points, as applicable, and the loan is prepayable at any time with no penalty. Additionally, a default under the terms of the senior notes of Casey's issued in connection with the leveraged recapitalization plan of Casey's, including a failure to pay the make-whole amount, will not constitute a default under the terms of Couche-Tard's new term loan facility.

Mr. Bouchard concluded, "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. In contrast to assertions made by Casey's, we obtained 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. Couche-Tard's financing does not require a make-whole payment at the expense of shareholders in any event. As we have previously pointed out, the "poison put" provision in the notes issued by Casey's, if enforceable, makes it approximately $110 million more expensive to acquire Casey's (based on current treasury rates), which equates to approximately $2.88 per share (after giving effect to the Casey's recapitalization), and thereby detracts from the value that may be received by the Casey's shareholders."

The tender offer documents, including the Offer to Purchase and the Letter of Transmittal and Couche-Tard's definitive proxy statement in connection with the solicitation of proxies for the 2010 annual meeting of shareholders of Casey's, have been filed with the Securities and Exchange Commission ("SEC").
