On March 5, 2009, The Williams Companies, Inc. (the "Company") completed a $600 million private offering of senior notes due 2020 (the "Notes") to certain institutional investors in an offering exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). The Notes were priced with an 8.75 percent coupon and at 99.159 percent to par, with a yield to investors of 8.875 percent. The Company intends to use the net proceeds from the offering for general corporate purposes, including enhancing the company's liquidity position and the funding of capital expenditures. A copy of the Company's press release announcing the same is attached as Exhibit 99.1.

The Notes were issued pursuant to an Indenture, dated as of March 5, 2009, between The Bank of New York Mellon Trust Company, N.A., as trustee, and the Company. The Notes are the Company's unsecured obligations ranking equally with the Company's other existing and future senior unsecured indebtedness.

The Notes bear interest at a rate of 8.75% per annum. The Company will pay interest on the Notes on January 15 and July 15 of each year, commencing on July 15, 2009. The Notes will mature on January 15, 2020. The Company may redeem some or all of the Notes at any time at the redemption prices described in the Indenture. The Indenture contains covenants that, among other things, restrict the Company's ability to grant liens on its assets and merge, consolidate or transfer or lease all or substantially all of its assets, subject to certain qualifications and exceptions.

The holders of the Notes are entitled to the benefits of a Registration Rights Agreement (the "Registration Rights Agreement") dated as of March 5, 2009, between the Company and Citigroup Global Markets Inc., acting on behalf of itself and the several initial purchasers listed on Schedule I thereto. Under the Registration Rights Agreement, the Company has agreed to file a registration statement with the Securities and Exchange Commission for an offer to exchange the Notes for new issues of substantially identical notes registered under the Securities Act on or before 180 days after March 5, 2009, and to use its commercially reasonable efforts to cause the registration statements to be declared effective on or prior to 270 days after March 5, 2009. The Company also may be required to file a shelf registration statement to cover resales of the Notes under certain circumstances. If the Company fails to satisfy certain of its obligations under the Registration Rights Agreement, it may be required to pay additional interest on the Notes.
