ODD LOTS

(See Section 1 of the Offer to Purchase and Instruction 6 of the Letter of Transmittal)

As described in Section 1 of the Offer to Purchase, under certain conditions, stockholders holding a total of fewer than an aggregate of 100 shares may have their shares tendered at or below the Purchase Price accepted for purchase before any proration of other tendered shares. This preference is not available to partial tenders or to beneficial or record holders of 100 or more shares in the aggregate, even if these holders have separate accounts or certificates representing fewer than 100 shares. Accordingly, this section is to be completed only if shares are being tendered by or on behalf of a person owning, beneficially or of record, an aggregate of fewer than 100 shares. The undersigned either (check one box):

☐   is the beneficial or record owner of an aggregate of fewer than 100 shares, all of which are being tendered; or

☐   is a broker, dealer, commercial bank, trust company or other nominee that (a) is tendering for the beneficial owner(s) shares with respect to which it is the record holder and (b) believes, based upon representations made to it by the beneficial owner(s), that each such person is the beneficial owner of an aggregate of fewer than 100 shares and is tendering all of such shares.

CONDITIONAL TENDER

A tendering stockholder may condition his, her or its tender of shares upon the Company purchasing a specified minimum number of the shares tendered, all as described in Section 6 of the Offer to Purchase. Unless at least the minimum number of shares you indicate below is purchased by the Company pursuant to the terms of the tender offer, none of the shares tendered will be purchased. It is the tendering stockholder’s responsibility to calculate that minimum number of shares that must be purchased if any are purchased, and each stockholder is urged to consult his, her or its own tax advisor. Unless this box has been checked and a minimum specified, your tender will be deemed unconditional.

☐   The minimum number of shares that must be purchased, if any are purchased, is:        shares

If, because of proration, the minimum number of shares designated will not be purchased, the Company may accept conditional tenders by random lot, if necessary.
