Item 5.03(a) -- Amendments to Bylaws

As previously reported by Eastman Chemical Company (the "Company") on its Form 8-K filed December 9, 2008, effective immediately after the Company's Annual Meeting of Stockholders on May 7, 2009 the positions of Chief Executive Officer and Chairman of the Board were separated.

The Board of Directors of the Company on May 7, 2009 amended the Company's Bylaws by adding the office of Chief Executive Officer to Sections 1.1 (stock certificate signatures), 2.6(a) (presiding officer of stockholder meetings), and
7.3 (voting of stock owned by the Company). These amendments provide the Chief Executive Officer the same powers and authority under the Bylaws of the Company as when the offices of Chairman and Chief Executive Officer were held by the same person.

The text of these Bylaw amendments is filed as an exhibit to this Current Report on Form 8-K, and a complete copy of the Company's Bylaws as amended is posted on the Company's Internet website (www.eastman.com) in the "Investors -- Corporate Governance -- Bylaws" section and will be filed as an exhibit to the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2009.
