(1) Pursuant to the terms of the Agreement and Plan of Merger, dated as of February 6, 2013, by and among Reliance Steel & Aluminum Co. ("Reliance"), Metals USA Holdings Corp. ("Metals USA") and RSAC Acquisition Corp., a wholly-owned subsidiary of Reliance (the "Merger Agreement"), each share of Metals USA common stock owned by the reporting person immediately prior to the effective time of the Merger (as defined in the Merger Agreement) converted at the effective time into the right to receive $20.65 in cash.
(2) Mr. Michelini is associated with Apollo Management, L.P. ("Apollo Management") and its affiliated managers, including Apollo Management V, L.P. Apollo Management V, L.P. serves as the manager or a special limited partner of the Apollo investment funds that hold shares of the common stock of Metals USA, and as such may be deemed to beneficially own the shares held by the Apollo investment funds. This report does not include any securities of Metals USA that are held by the Apollo investment funds or that may be deemed to be beneficially owned by Apollo Management or any of the other Apollo investment managers or investment advisors, and Mr. Michelini disclaims beneficial ownership of all such securities. This report shall not be deemed an admission that Mr. Michelini is the beneficial owner of, or has any pecuniary interest in, such securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.
(3) Pursuant to the terms of the Merger Agreement, each option to purchase Metals USA common stock owned by the reporting person, whether vested or unvested, that was outstanding immediately prior to the effective time of the Merger converted into the right to receive an amount in cash equal to the product of the number of shares of Metals USA common stock subject to the option and the excess, if any, of $20.65 over the exercise price per share of such option, less any required withholding taxes.
