The following is hereby inserted immediately prior to the first complete paragraph on page 19:

(C)

The following sentence is hereby inserted after the first complete paragraph on page 19:

"Although they were used as references, Merrill Lynch did not apply a PEG or enterprise value to estimated EBITDA multiple to derive the value of Sports Authority in the course of its analysis.

From these transactions, Merrill Lynch excluded retail sub-sectors that it deemed inappropriate bases for comparison."

The sixth sentence under the section entitled "Comparable Transactions Analysis" and the immediately following chart is hereby replaced with the following:

(2)

The section of the proxy statement entitled "Special Factors—Background of the Merger" is hereby supplemented as follows:

(A)

The following sentence is hereby inserted after the first sentence of the fourth paragraph:

"In its letter, Leonard Green stated that the Company's management team was important to the Company's future success and that Leonard Green intended to offer certain members of the Company's management team the opportunity to participate in the ownership of the Company following the closing of the transaction. The letter also stated that its proposal was conditioned, among other things, on reaching an agreement with the Company's ongoing management with respect to their investments and equity position in the Company and their continuing roles as managers of the Company."

(B)

The final paragraph of such section is hereby deleted and replaced with the following:

        "Over the following weeks, confidentiality agreements were entered into with certain interested parties and certain information regarding Sports Authority was provided to them. During the solicitation period, Merrill Lynch contacted a total of 34 parties. In addition to the 34 parties contacted by Merrill Lynch, three parties initiated contact with Merrill Lynch. Of the three parties to initiate contact with Merrill Lynch, one was a strategic buyer and two were financial buyers. Of the 34 parties contacted by Merrill Lynch, eight were strategic buyers and 26 were financial buyers. A total of six parties requested draft confidentiality agreements for the purpose of receiving access to confidential due diligence materials, and of those six, three executed confidentiality agreements with Sports Authority. Of the six parties that requested confidentiality agreements, one party was a strategic buyer and five parties were financial buyers. All three of the parties that executed confidentiality agreements were financial buyers. Each of these three parties received preliminary due diligence materials promptly after execution of confidentiality agreements.

        Negotiations with the parties that entered into confidentiality agreements during the solicitation period included negotiation regarding the terms of confidentiality agreements and provision of due diligence materials. Two of the three parties that entered into confidentiality agreements subsequently informed Merrill Lynch that they were not interested in pursuing a transaction with Sports Authority. The remaining party, prior to the end of the solicitation period, indicated a preliminary interest in obtaining due diligence information for the purposes of determining whether it could make a offer to acquire all of Sports Authority's outstanding shares for a price in excess of $37.25 per share. On February 10, 2006, the Special Committee designated this party an Excluded Party under the merger agreement, meaning that Sports Authority could continue discussions and negotiations with this party following the end of the solicitation period. However, this party subsequently informed Merrill Lynch that, based on the due diligence information it had received, it would not make an offer and terminated discussions. The solicitation period ended at 12:01 AM on Sunday, February 12, 2006."

The following sentence is hereby inserted at the end of the paragraph entitled "Positions with the Surviving Company":

"It is not currently expected that members of the Company's management will receive significant increases in compensation or other remunerations following the completion of the transaction."

(4)

The section entitled "Special Factors—Litigation" is hereby supplemented by adding the following the end of such section:

"On April 3, 2006, one of the plaintiffs filed motions for a preliminary injunction and expedited proceedings. The Delaware Court granted plaintiff's motion for expedited proceedings and ordered expedited discovery on April 5. The Court ordered consolidation of all four actions on April 12. Following expedited discovery, discussions and negotiations, the parties reached an agreement in principle to settle the lawsuits. The proposed settlement is subject to court approval following notice to the class and a hearing."
