(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. Accordingly, the Reporting Persons sold an aggregate of 5,681,818 shares of Common Stock and received a price per share of $19.74 (which is net of underwriting discounts and commissions) for an aggregate amount of $112,159,087.32.
(5) The 78,532,208 shares of Common Stock of the Company reported herein are beneficially owned directly by PVF. The Funds are members of PVF and own common units of PVF. At this time, the Funds' common units of PVF correspond to 47,853,611 shares of Common Stock.

(6) Goldman Sachs and GS Group may be deemed to beneficially own indirectly, in the aggregate, all of the Common Stock owned directly by PVF through the Funds because (i) affiliates of Goldman Sachs and GS Group are the general partner, managing general partner, managing partner, managing member or member of the Funds and (ii) the Funds control PVF and have the power to vote or dispose of the Common Stock owned by PVF. Goldman Sachs is a wholly-owned subsidiary of GS Group. Goldman Sachs is the investment manager of certain of the Funds.

GS Germany V and its general partner, GS GmbH, may be deemed to beneficially own indirectly 534,035 shares of Common Stock. GS Capital VI and its general partner, GSCP VI Advisors, may be deemed to beneficially own indirectly 10,396,674 shares of Common Stock (continued in footnote 8).
(8) GS VI Offshore and its general partner, GSCP VI Offshore Advisors, may be deemed to beneficially own indirectly 8,647,587 shares of Common Stock.

(9) The Reporting Persons disclaim beneficial ownership of all shares of Common Stock in excess of their pecuniary interest, if any, and this report shall not be deemed an admission that any such person or entity 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.
