        <footnote id="F1">Based on the closing price on the date of settlement.</footnote>
        <footnote id="F2">Each share of phantom stock converts into one share of common stock and was the economic equivalent thereof.  The reporting person settled 2,195 of his shares of phantom stock, which were held in the PNM Resources, Inc. Executive Savings Plan,  for cash at the prevailing market price of the company's common stock on the date of the transaction.  The  reporting person made such settlement pursuant to the one-time election that was available to participants in connection with the merger of the PNM Resources, Inc. Executive Savings Plan I with the PNM Resources, Inc. Executive Savings Plan II, which was completed in December 2008.  This Form 4/A is filed to amend the original Form 4 filed on 09/03/10, which did not state that 2,195 phantom shares were settled for cash in lieu of the company's common stock.</footnote>
