The interests of PVF LLC are held by a private investor group, which includes the GS Investing Entities. Affiliates of GS Group and Goldman Sachs are the general partner, managing general partner, manager partner, managing member or member of the GS Investing Entities and the GS Investing Entities control PVF LLC and have the power to vote and dispose of the common stock, par value $0.01 per share, of MRC GLOBAL INC. owned by PVF LLC.

The interests of PVF LLC are held by a private investor group, which includes the GS Investing Entities. The aggregate number of shares of common stock, par value $0.01 per share ("Common Stock"), of MRC GLOBAL INC. (the "Company") beneficially owned by PVF LLC based on available information is 55,532,208, which represents approximately 54.7% of the outstanding shares of Common Stock. PVF LLC is a party to a Governance Agreement, dated as of April 11, 2012 (the "Governance Agreement"), by and among the Company and PVF LLC. The Governance Agreement provides that for so long as PVF LLC beneficially owns at least 15% of the outstanding shares of Common Stock, PVF LLC has the right to nominate to the Company's board of directors a number of directors equal to the product of (i) the percentage of the total outstanding shares of Common Stock beneficially owned by PVF LLC multiplied by (ii) the total number of directors comprising the Company's board of directors (rounded up to the nearest whole number). At this time, PVF LLC has the right to nominate 7 of the Company's directors. Because the GS Investing Entities control PVF LLC and have the power to vote the Common Stock owned by PVF LLC, the GS Investing Entities will have the right to select the individuals that PVF LLC has the right to nominate under the Governance Agreement. The Amended and Restated Limited Liability Company Agreement of PVF LLC, dated as of October 31, 2007, as amended, by and among the GS Investing Entities and the other parties thereto (the "LLC Agreement"), contains certain provisions relating to transfer restrictions with respect to the interests of PVF LLC owned by the parties thereto.

Each of the GS Investing Entities, GS Group and Goldman Sachs disclaims beneficial ownership of any shares of Common Stock beneficially owned by the other parties to the LLC Agreement, except to the extent disclosed in this Schedule 13G.
