Item 3.01		Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

3In connection with the completion of the Merger, the Company notified The Nasdaq Stock Market, Inc. (“NASDAQ”) on October 2, 2009 that each share of the Company’s common stock, par value $0.01 per share (other than shares owned by IBM, Merger Sub or the Company) issued and outstanding immediately prior to the effective time of the Merger, had been converted into the right to receive $50.00 in cash, without interest and less any applicable withholding tax, and requested that NASDAQ file with the SEC an application on Form 25 to report that shares of the Company’s common stock are no longer listed on NASDAQ.

The Company will file a Form 15 Certification and Notice of Termination of Registration with the SEC to deregister its common stock under Section 12(g) of the Securities Exchange Act of 1934 (the “Exchange Act”), and to suspend the reporting obligations of the Company under Sections 13 and 15(d) of the Exchange Act.


Item 3.03		Material Modifications to Rights of Security Holders.

On October 2, 2009, as a result of the Merger, each share of the Company’s common stock (other than shares owned by IBM, Merger Sub or the Company) issued and outstanding immediately prior to the

effective time of the Merger was converted into the right to receive $50.00 in cash, without interest and less any applicable withholding tax.

In addition, on October 2, 2009, the Company entered into the First Supplemental Indenture (the “Supplemental Indenture”) with Wilmington Trust FSB, as successor trustee, related to the Convertible Notes. Pursuant to the Supplemental Indenture and in connection with the completion of the Merger, the Convertible Notes became convertible, at the option of the holder, into the right to receive $50.00 multiplied by 24.2843 (the applicable conversion rate of 21.3105 in effect immediately prior to the Merger increased by a “make-whole premium” of 2.9738) for each $1,000 principal amount of Convertible Notes submitted for conversion. The right of holders to surrender their Convertible Notes for conversion as a result of and in connection with the Merger will expire at 5:00 p.m., Eastern time, on November 2, 2009. The foregoing description of the Supplemental Indenture does not purport to be complete and is qualified in its entirety by reference to the Supplemental Indenture, which is filed as Exhibit 4.1 hereto and incorporated herein by reference.
