On May 15, 2014, Eastman Chemical Company (the “Company”) issued and sold $500 million aggregate principal amount of 4.65% notes due 2044 (the “Notes”) pursuant to the Underwriting Agreement (as defined below) and the Company’s Registration Statement on Form S-3 (Registration No. 333-181549) filed with, and declared effective by, the Securities and Exchange Commission (the “SEC”) on May 18, 2012 (the “Registration Statement”), the preliminary prospectus supplement and issuer free writing prospectus, each of which were filed with the SEC on May 6, 2014, and the prospectus supplement which was filed with the SEC on May 7, 2014. The Notes were issued under an indenture, dated as of June 5, 2012 (the “Indenture”), by and between the Company and Wells Fargo Bank, National Association, as trustee (the “Trustee”).

The Notes are unsecured, unsubordinated general obligations of the Company. Interest is payable semi-annually on April 15 and October 15 of each year, beginning on October 15, 2014, to the persons in whose names the Notes are registered in the security register at the close of business on the April 1 or October 1 preceding the relevant interest payment date, except that interest payable at maturity shall be paid to the same persons to whom principal of the Notes is payable.

The Company may redeem the Notes, in whole or in part at any time prior to April 15, 2044, at a redemption price equal to the sum of the principal being redeemed, plus a “make-whole” premium specified in the Notes and accrued and unpaid interest to the redemption date.

The Notes are redeemable on or after April 15, 2044 (six months prior to the maturity date) at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest to the redemption date.

The Indenture contains covenants that, among other things, restrict the ability of the Company to incur certain secured indebtedness, enter into sale and leaseback transactions and consolidate, merge or transfer all or substantially all of its assets and the assets of its subsidiaries on a consolidated basis. These covenants are subject to a number of important exceptions and qualifications. In addition, upon the occurrence of a Change of Control Triggering Event (as defined in the Indenture), the holders of the Notes will have the right to require the Company to repurchase all or a portion of the Notes at a price equal to 101% of their principal amount plus accrued and unpaid interest to the date of repurchase.

The Indenture also contains customary provisions for events of default including for failure to pay principal or interest when due, failure to perform covenants in the Indenture and failure to cure or obtain a waiver of such default upon notice, and certain events of bankruptcy, insolvency or reorganization. Subject to certain exceptions and conditions as set forth in the Indenture, in the case of an event of default, the principal amount of the Notes plus accrued and unpaid interest may be accelerated.

The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the complete terms of the Indenture, which is filed as Exhibit 4.1 to the Company’s Current Report on Form 8-K dated June 5, 2012, and the Notes, the form of which is filed as Exhibit 4.2 hereto, all of which are incorporated herein by reference.

The information contained under Item 1.01 above is incorporated herein by reference.

On May 6, 2014, the Company entered into an underwriting agreement (the “Underwriting Agreement”), with J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC, as representatives of several underwriters named therein (collectively, the “Underwriters”), with respect to the issuance and sale of the Notes.

The Underwriting Agreement includes customary representations, warranties and covenants by the Company. It also provides for customary indemnification by each of the Company and the respective Underwriters against certain liabilities arising out of or in connection with sale of the Notes and for customary contribution provisions in respect of those liabilities.

The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the complete terms of the Underwriting Agreement, a copy of which is filed as Exhibit 1.1 hereto and incorporated herein by reference.

The Company intends to use the net proceeds from the sale of the Notes for general corporate purposes, which may include working capital, capital expenditures, the repayment of indebtedness outstanding from time to time and other matters in connection with the implementation of the Company’s strategic initiatives.
