(f) Each of Mr. Khosla the persons set forth on Exhibit 99.2 is a citizen of the United States.

ITEM 3. Source and Amount of Funds or Other Consideration.

As further described in Item 4 below, the Reporting Persons acquired the Common Stock reported herein pursuant to the Exchange Offer (as defined below) and subsequent approval of the charter amendment described below that resulted in High Ridge, SS Onshore Fund, and Mardi Gras (collectively, the “Investment Vehicles”), which are ultimately controlled by Mr. Khosla, exchanging their Old Notes (as defined below) totaling $61,731,000, $3,928,000, and $11,544,000, respectively, for the Common Stock described in Item 4. As discussed in Item 4, the Old Notes (as defined below) were acquired by the Investment Vehicles using internally generated funds of the Investment Vehicles. The information set forth in Item 4 of this Schedule 13D is hereby incorporated herein by reference.

ITEM 4. Purpose of Transaction.

On October 6, 2011, the Issuer entered into a Restructuring Support and Lockup Letter Agreement (the “Noteholder Support Agreement”) with certain lenders, including the Investment Vehicles, (collectively, the “Supporting Noteholders”) who together held approximately 90% of the aggregate principal amount of the Issuer’s 10 1/2% Senior Secured Notes due 2012 (the “Old Notes”).

The Noteholder Support Agreement, along with separate agreements with the holders of the Issuer’s preferred stock, set forth the terms of the Issuer’s capital restructuring plan, under which the Issuer consummated an exchange offer (the “Exchange Offer”) to acquire all of the Old Notes in exchange for a combination of the Issuer’s equity securities, and either cash or new debt securities in an aggregate amount of $50 million (if the Exchange Offer is fully subscribed).

On December 22, 2011, the Issuer completed its out-of-court restructuring, which included the consummation of the purchase of $297,012,000 aggregate principal amount, or approximately 99%, of the Old Notes in exchange for shares of the Issuer’s newly issued Common Stock, shares of a new series of preferred stock (“New Preferred Stock”) that mandatorily converted into Common Stock, and approximately $50 million aggregate principal amount of newly issued Floating Rate Senior Secured Notes due 2016 (the “New Notes”). Dune also implemented a 1-for-100 reverse stock split.

Following this series of recapitalization transactions, contemplated by the Noteholder Support Agreement, the holders of Old Notes who had tendered their Old Notes in the Exchange Offer, including the Investment Vehicles, held approximately 97.1% of the shares of Common Stock. As a result of the exchange, (i) SV Master Fund owns 7,795,445 shares of Common Stock held by High Ridge; (ii) SS Onshore Fund owns 495,988 shares of Common Stock directly; and (iii) SS Offshore Fund owns 1,457,799 shares of Common Stock held by Mardi Gras. Also as of December 22, 2011, the Reporting Persons owned $12,867,167 in principal amount of New Notes as a result of the Exchange Offer.

The above summary of the material terms of the Noteholder Support Agreement is qualified in its entirety by reference to the text of the Noteholder Support Agreement, a copy of which is filed as Exhibit 99.3.

The Reporting Persons acquired the Common Stock for investment purposes and in the ordinary course of their investment trading business.

The Reporting Persons continuously assess the Issuer’s business, financial condition, results of operations and prospects, general economic conditions, other developments and additional investment opportunities.

The Reporting Persons expect to evaluate on an ongoing basis the Issuer’s financial condition and prospects and its interest in, and intentions with respect to, the Issuer and their investment in the securities of the Issuer, which review may be based on various factors, including the Issuer’s business and financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for the Issuer’s securities in particular, as well as other developments and other investment opportunities, which, if effected, could result in, among other things, any of the matters identified in Items 4(a)-(j) of Schedule 13D. Accordingly, each Reporting Person reserves the right to change its intentions and develop plans or proposals at any time, as it deems appropriate. In particular, each Reporting Person may at any time and from time to time, (i) dispose or transfer of all or a portion of the securities of the Issuer, including the shares of Common Stock and the New Notes, that the Reporting Persons now own or may hereafter acquire to any person or entity; (ii) in the open market, in privately negotiated transactions or otherwise, acquire additional shares of Common Stock or other securities of the Issuer; (iii) enter into derivative transactions with institutional counterparties with respect to the Issuer’s securities; (iv) cause or seek to cause the Issuer or any of its subsidiaries to acquire all or a portion of another person’s assets or business; (v) cause or seek to cause the Issuer or any of its subsidiaries to enter into one or more acquisitions, business combinations or mergers or to sell, transfer or otherwise dispose of all or any portion of its assets or business to any person or entity, including acquisitions, business combinations, mergers, sales, transfers and other dispositions; (vi) restructure the Issuer’s or any of its subsidiaries’ capitalization, indebtedness or holding company arrangements; (vii) make personnel changes to the present management of the Issuer deemed necessary or desirable; (viii) change the identity of the directors of the Issuer; (ix) make or propose any other material change in the Issuer’s or any of its subsidiaries’ corporate structure or business; or (x) engage in communications with one or more stockholders, officers or directors of the Issuer and other persons regarding any of the matters described in clauses (i) through (ix) above.

Except as set forth herein, the Reporting Persons do not have present plans or proposals at this time that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. The information set forth in Item 6 of this Schedule 13D is hereby incorporated herein by reference.

ITEM 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

On the consummation of the Exchange Offer, which occurred on December 22, 2011, the obligations of the Reporting Persons and the Investment Vehicles under the Noteholder Support Agreement, terminated. As a result, the Reporting Persons, the Investment Vehicles and other lenders party to the Noteholder Support Agreement (the “Other Lenders”) may no longer be deemed to be a “group” pursuant to Section 13(d)(3) of the Exchange Act. The Reporting Persons never expressly affirmed membership in any group with any of the Other Lenders, and disclaimed beneficial ownership of any Common Stock held by such lenders. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that the Reporting Persons or any of their respective affiliates were the beneficial owners of any Common Stock beneficially owned by any of the Other Lenders for purposes of Section 13(d) of the Exchange Act, the rules promulgated thereunder or for any other purpose.

On December 22, 2011, the Reporting Persons, along with certain of the Other Lenders, entered into a Registration Rights Agreement with the Issuer (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the Issuer is required to file a shelf registration statement within 60 days of December 22, 2011, and have the shelf registration statement declared effective within 180 days.
