"The Proposed Transaction is subject to customary closing conditions and Switchboard stockholder approval, which requires approval by two-thirds of Switchboard's outstanding shares, excluding those held by Viacom. "Other than as set forth herein, the Reporting Persons have no current plan or proposal which relates to, or would result in, any of the actions enumerated in subparagraphs (a) through (j) of Item 4 of Schedule 13D."

As a result of his stock ownership in NAI, Mr. Sumner M. Redstone is deemed the beneficial owner of 8,555,497 Common Shares, including 1,066,937 Common Shares underlying the Subject Warrants, and the Special Preferred Stock or approximately 31.9% of the issued and outstanding Common Shares (based on the number of Page 5 of 6 Common Shares that were reported by the Issuer to be issued and outstanding and assuming the exercise of all the Subject Warrants and such underlying shares to be issued and outstanding for purposes of this calculation).
