At the effective time of the Merger, each Share issued and outstanding immediately prior to the effective time of the Merger (other than Shares held by (i) Fairchild as treasury stock, or ON Semiconductor, Fairchild or their respective wholly owned subsidiaries (including Purchaser) immediately prior to the Effective Time, which Shares will be cancelled and will cease to exist, and (ii) stockholders of Fairchild who properly exercise appraisal rights under the Delaware General Corporation Law) will be cancelled and automatically converted into the right to receive an amount in cash equal to the Offer Price.

Payment for Shares will be in all cases made only after such Shares are accepted by Purchaser for payment pursuant to the Offer and the timely receipt by Computershare Trust Company, N.A. (the “Depositary”), of (a) certificates for such Shares or a Book-Entry Confirmation (as defined in the Offer to Purchase) with respect to such Shares pursuant to the procedures set forth in the Offer to Purchase, (b) a Letter of Transmittal properly completed and duly executed, with any required signature guarantees (or, in the case of a book-entry transfer, an Agent’s Message (as defined in the Offer to Purchase) in lieu of the Letter of Transmittal) and (c) any other documents required by the Letter of Transmittal. Accordingly, tendering stockholders may be paid at different times depending upon when certificates for Shares or Book-Entry Confirmation with respect to Shares are actually received by the Depositary.
