As of June 13, 2014, RCF IV owns 6,933,340 shares of Common Stock. Based on the foregoing, RCF IV may be deemed to have sole voting and dispositive power over, and therefore beneficial ownership of, approximately 2.8% of the issued and outstanding Common Stock of the Company.

As of June 13, 2014, RCA IV may be deemed to have sole voting and dispositive power over, and therefore beneficial ownership of, approximately 2.8% of the issued and outstanding Common Stock of the Company.

The percentage of beneficial ownership referenced above is calculated based upon 244,712,409 shares of the Common Stock of the Company outstanding as of May 1, 2014, as reported by the Company in its proxy statement dated May 13, 2014 filed by the Company with the SEC on May 13, 2014.

Based on the foregoing, each of RCF V, Associates V and RCA V may be deemed to have sole voting and dispositive power over, and therefore beneficial ownership of, approximately 1.5% of the issued and outstanding Common Stock of the Company. In addition, the members of RCA IV identified above own interests in RCA V in substantially the same proportion, with no member exercising voting and dispositive power over, and therefore beneficial ownership of, Common Stock of the Company held by RCF IV or RCF V, respectively.
