Icahn Enterprises GP is the general partner of Icahn Enterprises, which is the sole limited partner of Icahn Enterprises Holdings.

Each of High River and Barberry is primarily engaged in the business of investing in securities. Hopper is primarily engaged in the business of serving as the general partner of High River. Each of Icahn Master and Icahn Partners is primarily engaged in the business of investing in securities. Icahn Offshore is primarily engaged in the business of serving as the general partner of Icahn Master.

The name, citizenship, present principal occupation or employment and business address of each director and executive officer of the Reporting Persons are set forth in Schedule A attached hereto.

None of the Reporting Persons nor any manager or executive officer of the Reporting Persons, has, during the past five years, (a) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (b) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting, or mandating activities subject to, Federal or State securities laws or a finding of any violation with respect to such laws.


Item 3. Source and Amount of Funds or Other Consideration

The Reporting Persons may be deemed to be the beneficial owner of, in the aggregate, 4,818,832 Shares, which were purchased by the Reporting Persons collectively for an aggregate purchase price of approximately $82.7 million.

The source of funding for the Shares held by the Reporting Persons was the general working capital of the respective purchasers. The Shares held by the Reporting Persons are held in margin accounts together with other securities. Such margin accounts may from time to time have debit balances. Part of the purchase price of such Shares was obtained through margin borrowing.


Item 4. Purpose of Transaction

The Reporting Persons acquired their positions in the Shares in the belief that the Shares were undervalued.

The Reporting Persons have read Fir Tree Partners' statement setting forth their criticisms of the proposed acquisition of Bonanza Creek Energy and their reasons for intending to vote against it. While the Reporting Persons have not spoken with Fir Tree, they could not be more in agreement with the views expressed in the statement – especially with the assertion that the transaction "reminds us of SandRidge's prior history when this same management team acquired disparate assets and added leverage with reckless abandon."

The Reporting Persons obviously also intend to vote against the nonsensical Bonanza transaction. While the Reporting Persons have not spoken with any stockholders of the Issuer, including Fir Tree, they note that news reports indicate other large holders, including Susquehanna Advisors and Cannell Capital, are similarly opposed to the transaction and intend to vote against it.

Representatives of the Reporting Persons attempted today to reach James Bennett, the Chief Executive Officer of the Issuer, and intend to continue to seek to meet with him and his management team soon. The Reporting Persons look forward to hearing what possible justifications management could have for entering into such a seemingly ill-advised, dilutive and value-destructive acquisition and why they believe the transaction is anything more than an entrenchment technique.

The Reporting Persons also intend to have discussions with the Issuer's board of directors, other stockholders of the Issuer, and other relevant parties as they continue to evaluate the situation. The Reporting Persons are considering all their options and, while they have no present plan to do so, they reserve the right and are considering whether to propose other transactions which relate to or would result in one or more of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, including, without limitation, calling a special meeting of stockholders to seek to remove the Issuer's board of directors.

The Reporting Persons may, from time to time and at any time: (i) acquire additional Shares and/or other equity, debt, notes, instruments or other securities of the Issuer and/or its affiliates (collectively, "Securities") in the open market or otherwise; (ii) dispose of any or all of their Securities in the open market or otherwise; or (iii) engage in any hedging or similar transactions with respect to the Securities.


Item 5. Interest in Securities of the Issuer

(a) The Reporting Persons may be deemed to beneficially own, in the aggregate, 4,818,832 Shares, representing approximately 13.51% of the Issuer's outstanding Shares (based upon the 35,665,907 Shares outstanding as of November 14, 2017 as disclosed in that certain Agreement and Plan of Merger by and among the Issuer, Brook Merger Sub, Inc. and Bonanza Creek Energy, Inc., dated as of November 14, 2017, attached as Exhibit 2.1 to the Issuer's Current Report on Form 8-K filed with the Securities and Exchange Commission on November 15, 2017).

(b) High River has sole voting power and sole dispositive power with regard to 963,767 Shares. Each of Hopper, Barberry and Mr. Icahn has shared voting power and shared dispositive power with regard to such Shares. Icahn Master has sole voting power and sole dispositive power with regard to 1,567,970 Shares.

Icahn Partners has sole voting power and sole dispositive power with regard to 2,287,095 Shares. Each of Icahn Onshore, Icahn Capital, IPH, Icahn Enterprises Holdings, Icahn Enterprises GP, Beckton and Mr. Icahn has shared voting power and shared dispositive power with regard to such Shares.

Each of Hopper, Barberry and Mr. Icahn, by virtue of their relationships to High River (as disclosed in Item 2), may be deemed to indirectly beneficially own (as that term is defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended, the "Act") the Shares which High River directly beneficially owns. Each of Hopper, Barberry and Mr. Icahn disclaims beneficial ownership of such Shares for all other purposes. Each of Icahn Offshore, Icahn Capital, IPH, Icahn Enterprises Holdings, Icahn Enterprises GP, Beckton and Mr. Icahn, by virtue of their relationships to Icahn Master (as disclosed in Item 2), may be deemed to indirectly beneficially own (as that term is defined in Rule 13d-3 under the Act) the Shares which Icahn Master directly beneficially owns. Each of Icahn Offshore, Icahn Capital, IPH, Icahn Enterprises Holdings, Icahn Enterprises GP, Beckton and Mr. Icahn disclaims beneficial ownership of such Shares for all other purposes. Each of Icahn Onshore, Icahn Capital, IPH, Icahn Enterprises Holdings, Icahn Enterprises GP, Beckton and Mr. Icahn, by virtue of their relationships to Icahn Partners (as disclosed in Item 2), may be deemed to indirectly beneficially own (as that term is defined in Rule 13d-3 under the Act) the Shares which Icahn Partners directly beneficially owns. Each of Icahn Onshore, Icahn Capital, IPH, Icahn Enterprises Holdings, Icahn Enterprises GP, Beckton and Mr. Icahn disclaims beneficial ownership of such Shares for all other purposes.

(c) The following table sets forth all transactions with respect to Shares effected during the past sixty (60) days by any of the Reporting Persons.
