On April 13, 2010, Worthington Industries, Inc. (the “Company”) completed the public offering (the “Notes Offering”) of $150 million aggregate principal amount of its 6.50% Notes due 2020 (the “Notes”). The Notes were offered pursuant to the prospectus supplement dated April 8, 2010, to the prospectus dated April 8, 2010 (together, the “Prospectus”), which forms part of the Company’s effective registration statement on Form S-3 (File No. 333-165942) filed with the Securities and Exchange Commission (the “SEC”) on April 8, 2010.

The Notes are registered under the Securities Act of 1933, as amended, pursuant to the Company’s effective registration statement on Form S-3 (File No. 333-165942) filed with the Securities and Exchange Commission on April 8, 2010. The Company filed a prospectus supplement dated April 8, 2010, to the prospectus dated April 8, 2010 (together, the “Prospectus”), relating to the Notes.

The sale of the Notes was made pursuant to the terms of an Underwriting Agreement dated April 8, 2010 (the “Underwriting Agreement”) between the Company and Credit Suisse Securities (USA) LLC and Wells Fargo Securities, LLC, as representative of the several underwriters named in the Underwriting Agreement (the “Underwriters”). The Underwriting Agreement includes the terms and conditions of the offer and sale of the Notes, indemnification and contribution obligations and other terms and conditions customary in agreements of this type.

The terms of the Notes are governed by an Indenture dated as of April 13, 2010 (the “Base Indenture”) between the Company and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by a First Supplemental Indenture dated as of April 13, 2010 (the “Supplemental Indenture”) between the Company and the Trustee.

The Notes are senior unsecured obligations of the Company and rank equal in right of payment with the Company’s existing and future unsecured and unsubordinated indebtedness. Interest on the Notes will accrue at a rate of 6.50% per annum and is payable on April 15 and October 15 of each year, commencing October 15, 2010. The Notes mature on April 15, 2020. The terms of the Notes are further described in the Prospectus.

Certain of the Underwriters and their affiliates have provided from time to time, and may provide in the future, investment and commercial banking and financial advisory services to the Company and its affiliates in the ordinary course of business, for which they have received and may continue to receive customary fees and commissions. Affiliates of Wells Fargo Securities, LLC, Credit Suisse Securities (USA) LLC and certain other Underwriters are lenders under the Company’s revolving credit facility, and an affiliate of Wells Fargo Securities, LLC acts as a co-documentation agent under the revolving credit facility. The Company intends to use the net proceeds from the Notes Offering to repay a portion of the outstanding borrowings under its revolving credit facility and amounts outstanding under its revolving trade accounts receivable securitization facility and, therefore, affiliates of the Underwriters that are lenders under the Company’s revolving credit facility will receive a portion of the net proceeds from the Notes Offering.
