Cautionary Statements Regarding Forward-Looking Information

This Current Report on Form 8-K contains forward looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are based on certain assumptions and describe future plans, strategies and expectations of Hudson City and M&T.  Such forward-looking statements may be identified by the use of such words as "may," "believe," "expect," "anticipate," "should," "plan," "estimate," "predict," "continue," and "potential" or the negative of these terms or other comparable terminology. Examples of forward-looking statements include, but are not limited to, estimates with respect to the financial condition, results of operations and business of Hudson City and M&T, and their respective strategies, plans, objectives, expectations and intentions, including the Merger, and other statements contained in this Current Report on Form 8-K that are not historical facts.  Hudson City's and M&T's ability to predict results or the actual effect of future plans or strategies, including the Merger and Hudson City's implementation of its strategic plan, is inherently uncertain and actual results and performance could differ materially from those contemplated or implied by these forward-looking statements. They can be affected by inaccurate assumptions Hudson City and M&T might make or by known or unknown risks and uncertainties.  Factors that could cause assumptions to be incorrect include, but are not limited to, changes in interest rates, general economic conditions, legislative, regulatory and public policy changes, further delays in closing the Merger and the ability of Hudson City or M&T to obtain regulatory approvals and meet other closing conditions to the Merger. These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. For a summary of important factors that could affect Hudson City's forward-looking statements, please refer to Hudson City Bancorp, Inc.'s filings with the Securities and Exchange Commission ("SEC") available at www.sec.gov. For a summary of important factors that could affect M&T's forward-looking statements, please refer to M&T's filings with the SEC available at www.sec.gov. Neither Hudson City nor M&T intends to update any of the forward-looking statements after the date of this Current Report on Form 8-K or to conform these statements to actual events.
