Accordingly, by checking this box instead of one of the price boxes below, the undersigned hereby tenders its Shares at, and is willing to accept, the Final Purchase Price as determined by the Company in accordance with the terms and subject to the conditions of the Offer. The undersigned understands that checking this box will result in its Shares being deemed to have been tendered at $77.00 per Share, which is the low end of the price range in the Offer, for purposes of determining the Final Purchase Price. The undersigned also understands that this may have the effect of lowering the Final Purchase Price and could result in the undersigned receiving a per Share price as low as $77.00, the low end of the price range in the Offer, less any applicable withholding taxes and without interest. The undersigned also understands that the Final Purchase Price is subject to and will not exceed the Final Price Cap. To the extent that the Final Price Cap is determined to be less than $77.00 per Share, which is the low end of the price range in the Offer, the undersigned understands that its Shares will not be purchased.

ODD LOTS
(See Instruction 14 of the Letter of Transmittal)

        As described in Section 1 of the Offer to Purchase, under certain conditions, shareholders holding less than 100 Shares may have their Shares accepted for payment before any proration of other tendered Shares. This preference is not available to partial tenders, or to beneficial or record holders of an aggregate of 100 or more Shares, even if such holders have separate accounts or certificates representing less 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 less than 100 Shares. The undersigned certifies that it either (check one box):

o

owns, beneficially or of record, an aggregate of less than 100 Shares and is tendering all such Shares; or

o

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

CONDITIONAL TENDER
(See Instruction 13 of the Letter of Transmittal)

        A shareholder may tender Shares subject to the condition that a specified minimum number of the shareholder's Shares tendered pursuant to the Letter of Transmittal must be purchased if any Shares tendered are purchased, all as described in the Offer to Purchase and particularly in Section 6 thereof. Unless at least that minimum number of Shares indicated 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 shareholder's responsibility to calculate that minimum number of Shares that must be purchased if any are purchased, and the Company urges shareholders to consult their own financial or tax advisors before completing this section. Unless this box has been checked and a minimum specified, the tender will be deemed unconditional.

o

The minimum number of Shares that must be purchased, if any are purchased, is:                  Shares.

3

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 box:

o

The tendered Shares represent all Shares held by the undersigned.
