FORWARD-LOOKING STATEMENTS

This Proxy Statement contains forward-looking statements made pursuant to the safe harbor provisions of Section 21E of the Securities

Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995 (PSLRA). These statements, which are based on our

beliefs and expectations as to future outcomes, include, among others, statements about our future operating results, business plans,

objectives, pipeline advancements, benefits and popularity of our products, and any other statements that contain the words believe, seek,

expect, anticipate, forecast, project, intend, estimate, should, could, may, will, plan, or similar expressions, and any other statements

contained or incorporated by reference into this Proxy Statement that are not historical facts. These forward-looking statements are subject

to certain risks and uncertainties, such as those described in our periodic reports filed with the Securities and Exchange Commission

(SEC), that could cause actual results to differ materially from anticipated results. These statements may also be based on standards for

measuring progress that are still developing and on assumptions that are subject to change in the future. Consequently, such

forward-looking statements are qualified by the cautionary statements, cautionary language, and risk factors set forth in our periodic

reports and documents filed with the SEC, including our most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and

Current Reports on Form 8-K. We claim the protection of the safe harbor contained in the PSLRA for forward-looking statements. Our

forward-looking statements speak only as of the date of this Proxy Statement or as of the date they are made, and we assume no

obligation to update or revise the information contained in this Proxy Statement whether as a result of new information, future events, or

any other reason. Our corporate responsibility-related goals are aspirational and may change. Statements regarding our goals are not

guarantees or promises that they will be met. The inclusion of information in our Corporate Responsibility and Public Benefit Report should

not be construed as a characterization of the materiality or financial impact of that information with respect to us or for purposes of this

Proxy Statement or any of our SEC filings.
