Item 3.03. Material Modification to Rights of Security Holders

On September 11, 2012, we entered into Amendment No. 1 to the Tax Benefit Preservation Plan (the "TBPP") between us and Computershare Trust Company, N.A., as rights agent. The TBPP, which is designed to preserve our substantial tax assets, was originally entered into in September 2009 and was scheduled to expire at the close of business on September 11, 2012. Amendment No. 1 to the TBPP, which was unanimously approved by our Board of Directors, extends the expiration date of the TBPP to September 30, 2015 (subject to other earlier termination events, including final adjournment of our 2013 annual meeting of shareholders if shareholder approval of the extension has not been received prior to that time).

The original TBPP is described in and included as an exhibit to our Current Report on Form 8-K filed September 11, 2009. Amendment No. 1 to the TBPP is filed as Exhibit 4 hereto and our news release announcing the extension of the TBPP is filed as Exhibit 99 hereto, and each is incorporated by reference herein.
