Footnotes

F1: 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. As such proration and allocation calculations have not yet been completed as of the date of this filing, it is not possible to determine the exact amount of Merger consideration to be received by the reporting person in the Merger. The number of shares reported is a good faith estimate and we intend to file an amendment to this Form 4 promptly after the final proration calculations are complete.

F2: Received in exchange for 1,472,189 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.

F3: Received in exchange for 24,502 shares of TALX common stock in connection with the Merger.

F4: The option vests in full on 5/15/07.

F5: Acquired pursuant to the Merger described in footnote 1 above. 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.
