By checking ONE of the following boxes below INSTEAD OF THE BOX UNDER “Shares Tendered at Price Determined by the Company Pursuant to the Offer,” the undersigned hereby tenders shares at the price checked. This action could result in none of the shares being purchased if the purchase price determined by the Company for the shares is less than the price checked below. A STOCKHOLDER WHO DESIRES TO TENDER SHARES AT MORE THAN ONE PRICE MUST COMPLETE A SEPARATE NOTICE OF GUARANTEED DELIVERY AND/OR LETTER OF TRANSMITTAL FOR EACH PRICE AT WHICH SHARES ARE TENDERED.

Shares Tendered At A Price Determined By the Company Pursuant To The Offer:

¨ By checking the box to the left INSTEAD OF ONE OF THE BOXES UNDER “Shares Tendered at a Price Determined by You,” the undersigned hereby tenders shares at the purchase price, as the same shall be determined by the Company in accordance with the terms of the Offer. For purposes of determining the purchase price, those shares tendered by the undersigned agreeing to accept the purchase price determined by the Company in the Offer will be deemed to be tendered at the minimum price of $82.00.

The undersigned wants to maximize the chance of having the Company purchase all of the shares the undersigned is tendering (subject to the possibility of proration). Accordingly, by checking this box instead of one of the price boxes above, the undersigned hereby tenders shares at, and is willing to accept, the purchase price determined by the Company in accordance with the terms of the Offer. THIS ACTION COULD LOWER THE PURCHASE PRICE AND COULD RESULT IN RECEIVING THE MINIMUM PRICE OF $82.00 PER SHARE.

Odd Lots This Section applies only to holders of less than 100 shares (“odd lots”) See Section 1 of the Offer to Purchase)

As described in Section 1 of the Offer to Purchase, under certain conditions, shareholders with fewer than 100 shares who tender at or below the price at which shares are purchased in the Offer may have their shares

accepted for payment before any proration of the purchase of other tendered shares. This priority is not available to partial tenders, or to beneficial or record holders of an aggregate of 100 or more 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 (only check one block):

¨ is the beneficial owner 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 the shares.

Conditional Tender (See Section 6 of the Offer to Purchase)

A tendering shareholder may condition his or her tender of shares upon the Company purchasing a specified minimum number of shares tendered, 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 Offer, none of the shares tendered by you will be purchased. It is the tendering stockholder’s responsibility to calculate the minimum number of shares that must be purchased if any are purchased, and each stockholder is urged to consult his or her own tax advisor before completing this section. 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 from me, if any are purchased from me, 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. However, to be eligible for purchase by random lot, the tendering shareholder must have tendered all of his or her shares and checked this block:

¨ The tendered shares represent all shares held by the undersigned.
