(1) Acquired pursuant to the merger (Merger) contemplated by the Agreement and Plan of Merger dated as of February 14, 2007 by and among TALX Corporation (TALX), Equifax Inc. (Equifax) & Chipper Corporation (Merger Agreement). At the effective time of the Merger, each outstanding share of TALX common stock, par value $.01, was converted into the right to receive either 0.861 shares of Equifax common stock, par value $1.25, or $35.50 in cash, or a combination of both, at the election of the reporting person, subject to proration and allocation procedures set forth in the Merger Agreement.
(2) Received in exchange for shares of TALX common stock in connection with the Merger. On 5/15/07, the effective date of the Merger, the closing price of TALX's common stock was $35.45 per share, and the closing price of Equifax's common stock was $41.32 per share.
(3) Previously reported as being directly owned.
(4) Held by family foundation established under Section 501(c)(3) of the Internal Revenue Code in which reporting person holds voting and investment power. Reporting person disclaims beneficial ownership of these shares, except to the extent of his pecuniary interest therein.
(5) Held by a trust established by reporting person's spouse. Reporting person is co-trustee with spouse. Reporting person disclaims beneficial ownership of these shares, except to the extent of his pecuniary interest therein.
(6) Grantor retained annuity trust established by reporting person. Reporting person is trustee. Reporting person disclaims beneficial ownership of these shares, except to the extent of his pecuniary interest therein.

At the effective time of the Merger, each TALX stock option that was outstanding and unexercised immediately prior to the effective time of the Merger was converted automatically into a fully vested option to purchase Equifax common stock. The number of shares of Equifax common stock subject to the Equifax stock option is equal to the product of the number of shares of TALX common stock subject to the TALX stock option & the exchange ratio determined pursuant to the Merger Agreement of 0.861, rounded down to the nearest whole share. The exercise price per share of Equifax common stock subject to the new Equifax stock option is equal to the exercise price per share of TALX common stock under the TALX stock option divided by the exchange ratio, rounded up to the nearest whole cent.
