Item 5. Interest in Securities of the Issuer
     Item 5 of the Schedule 13D is hereby amended and supplemented by deleting Items 5(a), 5(b) and 5(e) and adding the following:
     (a),(b) and (e) On November 10, 2010, OFS Energy distributed 12,967,408 shares of the Consideration Shares (1) to the members of OFS Energy in an in-kind, pro rata distribution in respect of their ownership interests in OFS Energy and (2) to certain other persons pursuant to the OFS Energy Services, LLC Transaction Bonus Plan, a copy of which is attached as Exhibit 99.2 to the Base Schedule 13D (“Transfer I”). On that same day, OFS Holdings distributed 104,749 of the shares received in Transfer I to certain former employees of OFS Holdings pursuant to the OFS Holdings, LLC Amended and Restated Participation Incentive Plan, a copy of which is attached as Exhibit 99.3 to the Base Schedule 13D (“Transfer II”). On January 7, 2011, OFS Holdings transferred 11,351,551 shares of the Consideration Shares received in Transfer I to its member, OFS Finance, 10,870,349 of which were transferred in an in-kind, pro rata distribution to OFS Finance in respect of its membership interest in OFS Holdings, and 481,202 of which were distributed to OFS Finance in exchange for OFS Finance’s agreement to cause OFS Holdings to distribute cash to the minority member of OFS Holdings in lieu of such member’s pro rata allocation of the Consideration Shares (“Transfer III”). On April 1, 2011, OFS Energy distributed 99,069 shares of the Consideration Shares to certain persons pursuant to the OFS Energy Services, LLC Transaction Bonus Plan (“Transfer IV”). On April 4, 2011, OFS Energy distributed 54,939 shares of the Cons ideration Shares to certain persons pursuant to the OFS Energy Services, LLC Transaction Bonus Plan (“Transfer V”). On May 2, 2011, OFS Finance sold an aggregate of 10,870,349 shares of Consideration Shares at a price per share of $17.63 through a block trade with a broker-dealer to whom it paid customary brokerage fees (“Transfer VI”). These shares of Consideration Shares were sold by OFS Finance pursuant to Rule 144 under the Securities Act, and accordingly a Form 144 was filed by OFS Finance with the SEC on May 2, 2011, which disclosed that the maximum number of shares that could be sold during the three month period covered by the Rule 144 filing would be 10,870,349 shares.
     Following Transfer VI, as of May 4, 2011, the interests in the Common Stock of each Reporting Person is as follows (the percentages set forth in this Item 5 are calculated based upon the number of shares of Common Stock outstanding as of March 14, 2011 based on the Issuer’s disclosure in its Proxy Statement for the 2011 Annual Meeting of Stockholders on Schedule 14A, filed April 13, 2011):
     (i) OFS Energy beneficially owns an aggregate of 2,685,817 shares of Common Stock, representing 1.9% of the outstanding shares of Common Stock. OFS Energy has the shared power to vote or direct the vote of 2,685,817 shares of Common Stock and the shared power to dispose of or direct the disposition of 309,817 shares of Common Stock. OFS Energy ceased to be the beneficial owner of more than five percent of the outstanding Common Stock on November 10, 2010.
