(3)	Due to the electronic system's limitation of 10 Reporting Persons per joint filing, this statement is being filed in duplicate.
(4)	Pursuant to an underwriting agreement, dated April 11, 2012 (the "Underwriting Agreement"), and in connection with the registered public offering (the "Offering") of shares of common stock, par value $0.01 per share (the "Common Stock"), of MRC Global Inc. (the "Company"), pursuant to the final prospectus filed by the Company on April 12, 2012 (the "Final Prospectus"), which offering was consummated on April 17, 2012, PVF sold 5,681,818 shares of Common Stock. Pursuant to the Final Prospectus, the public offering price in the Offering of Common Stock by the Company was $21.00 per share of Common Stock and the underwriting discount was $1.26 per share of Common Stock.
