The Offer is being made pursuant to the Agreement and Plan of Merger, dated as of July 1, 2014 (the “Merger Agreement”), among Hillshire Brands, Tyson and Purchaser. The Merger Agreement provides, among other things, that as soon as possible following the consummation of the Offer and the satisfaction or waiver of the other conditions set forth in the Merger Agreement, Purchaser will merge with and into Hillshire Brands (the “Merger”), with Hillshire Brands continuing as the surviving corporation and a wholly owned subsidiary of Tyson. At the effective time of the Merger, each outstanding Share (other than any Shares held by Hillshire Brands, Tyson or any subsidiary of Hillshire Brands or Tyson (including Purchaser)) will be converted into the right to receive the price per Share paid in the Offer, net to the seller in cash, without interest, subject to any withholding of taxes required by applicable law. No appraisal rights are available to holders of Shares in connection with the Offer, and we do not expect appraisal rights to be available to holders of Shares in connection with the Merger. The Merger Agreement is more fully described in Section 13 of the Offer to Purchase.

The Board of Directors of Hillshire Brands (the “Hillshire Brands Board”) has unanimously (i) determined that the Merger Agreement, the Offer, the Merger and the other transactions contemplated by the Merger Agreement are advisable, fair to and in the best interests of Hillshire Brands and Hillshire Brands’ stockholders, (ii) approved the Merger Agreement and consummation of the transactions contemplated thereby and (iii) subject to the terms of the Merger Agreement, resolved to recommend that Hillshire Brands’ stockholders accept the Offer and tender their shares pursuant to the Offer and, if required by applicable law, vote in favor of the approval of the Merger. The Hillshire Brands Board recommends that Hillshire Brands’ stockholders accept the Offer and tender their Shares pursuant to the Offer. Hillshire Brands has been advised that all of its directors and executive officers intend to tender all of their Shares pursuant to the Offer.

The Offer is conditioned upon, among other things, (i) there being validly tendered, and not validly withdrawn, prior to the expiration of the Offer, a number of Shares (excluding shares tendered pursuant to notices of guaranteed delivery for which Shares have not been delivered) that, together with the Shares then beneficially owned by Tyson and/or Purchaser, represents at least two-thirds of the total number of Shares outstanding as of the expiration of the Offer and (ii) expiration or termination of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended, and the regulations promulgated thereunder. The Offer is not conditioned upon Tyson or Purchaser obtaining financing. The Offer is also subject to the other conditions described in Section 15 of the Offer to Purchase.

Purchaser will not pay any fees or commissions to any broker, dealer or any other person (other than to the Information Agent and the Depositary as described in the Offer to Purchase) for soliciting tenders of Shares pursuant to the Offer. Purchaser will, however, upon request, reimburse brokers, dealers, commercial banks, trust companies and other nominees for reasonable and necessary costs and expenses incurred by them in forwarding the enclosed materials to their clients.

Purchaser will pay all stock transfer taxes applicable to its purchase of Shares pursuant to the Offer, subject to Instruction 6 of the Letter of Transmittal.

In order to take advantage of the Offer, a duly executed and properly completed Letter of Transmittal (or a manually signed facsimile thereof), or an Agent’s Message (as defined in the Offer to Purchase) in connection with a book-entry transfer of Shares, and any other required documents, should be sent to the Depositary, and certificates representing the tendered Shares should be delivered or such Shares should be tendered by book-entry transfer, all in accordance with the instructions contained in the Letter of Transmittal and the Offer to Purchase.

2

If holders of Shares wish to tender, but it is impracticable for them to forward their certificates or other required documents or to complete the procedures for delivery by book-entry transfer prior to the expiration of the Offer, a tender may be effected by following the guaranteed delivery procedures described in Section 3 of the Offer to Purchase.

Any inquiries you may have with respect to the Offer should be addressed to, and additional copies of the enclosed materials may be obtained from, the undersigned at the addresses and telephone numbers set forth on the back cover of the Offer to Purchase.

Very truly yours,

MACKENZIE PARTNERS, INC.
