The Tender Offer Statement (including an Offer to Purchase, a related Letter of Transmittal and other offer documents) and Solicitation/Recommendation will contain important information that should be read carefully and considered before any decision is made with respect to the tender offer. These materials will be sent free of charge to all shareholders of the Company when available. In addition, all of these materials (and all other materials filed by the Company with the SEC) will be available at no charge from the SEC through its website at

Customary Note Regarding Forward-Looking Statements

This filing contains forward-looking statements with respect to the tender offer and related transactions, including the benefits expected from the acquisition and the expected timing of the completion of the transaction. When used in this filing, the words “can,” “will,” “intends,” “expects,” “is expected,” similar expressions and any other statements that are not historical facts are intended to identify those assertions as forward-looking statements. Such statements are based on a number of assumptions that could ultimately prove inaccurate, and are subject to a number of risk factors, including uncertainties regarding the timing of the closing of the transaction, uncertainties as to how many shareholders of the Company may tender their stock in the tender offer, the possibility that a government entity may prohibit, decry or refuse to grant approval for the consummation of the transaction, and general economic and business conditions. The Company does not assume any obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise. Factors that could cause actual results of the tender offer to differ materially include the following: the risk of failing to obtain any regulatory approvals or satisfy conditions to the transaction, the risk that Parent is unable to obtain adequate financing, the risk that the transaction will not close or that closing will be delayed, the risk that the Company’s business will suffer due to uncertainty related to the transaction, the competitive environment in our industry and competitive responses to the transaction, as well as risk factors set forth above. Further information on factors that could affect the Company’s financial results is provided in documents filed by the Company with the SEC, including the Company’s recent filings on Form 10-K and Forms 10-Q.
