9.                                      Non-Disparagement.  Each of Purchasers and the Company shall not, and shall cause their respective controlled Affiliates not to, and shall instruct and use their reasonable best efforts to cause their respective directors, officers, employees, advisors and representatives not to, make (or authorize the making of) any statement publicly for a period of two (2) years from the date hereof about this Agreement, any of the Transaction Documents, the Apollo Agreements or the Transactions or about the Purchasers or the Company or its or their respective Affiliates that denigrates or disparages the Company or the Company Releasees (in the case of Purchasers) or Purchasers or the Purchasers Releasees (in the case of the Company), including without limitation, any statement that is critical of the Company or the Purchasers or their respective Affiliates, as applicable, or (in the case of the Purchasers only) that expresses a view regarding the financial position of the Company or its future prospects (a “Prohibited Statement”), provided, however, that for the avoidance of doubt the foregoing shall not be deemed to prevent or impair any person covered thereby from testifying in any legal or administrative proceeding, responding to inquiries or requests for information by any regulator or auditor, or taking any other action that is, in the opinion of legal counsel for a Party, required by law, or to prevent the Parties from making statements in any pleadings, court papers or in open court in any action brought by one of the Parties in connection with a breach of this Agreement or the promissory notes or in any action brought by any other person relating to this Agreement, the Purchase Agreement, the Original Agreement, the Investors Rights Agreement, the Royalty Agreement, the Apollo Agreements or the Transactions.  As used in this Section 9, a statement is made “publicly” if it is made to a person who is not a officer, director, employee, advisor or representative of the Company or the Purchasers or its or their respective Affiliates, except that statements made to members of the immediate family (as defined in the Corporate Governance rules of the New York Stock Exchange as in effect on the date of this Agreement) shall not be deemed to be made publicly.  If during the two (2) years after the date hereof a Party or one of its current or future directors, officers and employees makes a Prohibited Statement, then another Party may notify that Party of its objection to the statement, providing reasonable detail regarding such statement.  Promptly following receipt of such notice, the Party receiving the notice shall attempt to confirm the facts surrounding the alleged Prohibited Statement, and if in its good faith opinion the contents of the notice are accurate, then the Party receiving the notice shall promptly make an appropriate public retraction or correction. Each of the Parties agrees that the rights and remedies for noncompliance with this Section 9 shall include having such provisions specifically enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such breach or threatened breach shall cause irreparable injury to the non-breaching Party and that money damages would not provide an adequate remedy to such Party.

5

12.                               Indemnification.  The Company hereby agrees to indemnify Purchasers and their Affiliates and their respective directors, trustees, officers, employees, partners, members, attorneys and agents (collectively, “Indemnified Party”) from, and hold each of them harmless against, any and all losses, liabilities, claims, damages or expenses (collectively, “Losses”) incurred by any of them arising out of or by reason of any investigation or litigation or other proceedings (including any threatened investigation or litigation or other proceedings) commenced or threatened by any person (including the Company or its shareholders but excluding any Indemnified Party and any Affiliate of or investor in an Indemnified Party (except to the extent such person who is not a Purchaser or an Affiliate of the Purchaser is a direct or indirect shareholder in the Company and acted in such capacity in connection with any such investigations, litigations or other proceedings)) relating to this Agreement, the Transaction Documents, the promissory notes or the transactions related hereto or thereto, including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation or litigation or other proceedings; provided, however, in no event shall any such indemnification obligation apply to any breach by the Purchasers of the provisions of this Agreement. Notwithstanding anything to the contrary in this Agreement, the Company is not obligated to indemnify or defend Indemnified Party against any third-party claim if such third-party claim or corresponding Losses arise out of or result from, in whole or in part, Indemnified Party’s (i) gross negligence or more culpable act or omission (including recklessness or willful misconduct), or (ii) bad faith failure to comply with any of its obligations set forth in this

6

Agreement, the Transaction Documents, the promissory notes or the transactions related hereto or thereto.

Item 1.02                                           Termination of a Material Definitive Agreement.

On March 7, 2013, we entered into a Termination and Release Agreement with certain affiliates of certain investment funds managed by Apollo Global Management, LLC (which we refer to collectively as the Apollo Parties) that terminates the Securities Purchase Agreement, Investors Rights Agreement and Royalty Agreement entered into with the Apollo Parties in November, 2012 (as amended in December, 2012).  These agreements related to a potential financing transaction (the “Apollo Financing”) with the Apollo Parties that is described in our Current Reports on Form 8-K filed with the Securities and Exchange Commission on  December 4, 2012 and December 26, 2012 and our definitive proxy statement on Form 14A filed with the Securities and Exchange Commission on December 26, 2012. The Apollo Financing was terminated as a result of concerns about Prospect Global’s ability to obtain the necessary shareholder approvals for the Apollo Financing.

Under the Apollo Financing, the Apollo Parties would have paid us $100 million and received upon closing $100 million in newly issued 7-year 10% Convertible Springing 2nd Lien Notes.  The Notes would have been convertible into shares of our common stock at an initial conversion price of $2.70 per share, subject to anti-dilution provisions.  The Notes would have voted on an as converted basis with our common stock.  As part of the Apollo Financing, the Apollo Parties would have received Warrants to purchase approximately 25.9 million shares of our common stock at $2.70 per share and approximately 21.5 million shares of our common stock at $3.25 per share, each subject to anti-dilution provisions.  Under the Royalty Agreement, to which Buffalo Management LLC was also a party, upon issuance of the Notes, Buffalo’s existing right to receive 2% of our gross revenues would have terminated, and thereafter each of Buffalo and the Apollo Parties would have had the right to receive the greater of 1% of our gross revenues or 1% of the gross sales of our American West Potash subsidiary.  Buffalo Management is controlled by Chad Brownstein, our executive vice-chairman.  Barry Munitz, our board chair, and Patrick Avery, our former chief executive officer and a former director of Prospect Global, own minority non-voting interests in Buffalo Management.

Upon execution of the Termination and Release Agreement (i) we paid the Apollo Parties $750,000 in cash and issued two Promissory Notes totaling approximately $6.75 million (described in Item 2.03 below) as a break up and release payment and (ii) we reimbursed the Apollo Parties for $2.16 million of expenses incurred by them in connection with the Apollo Financing.  The agreement also contains mutual releases.

Item 2.03                                           Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The two Promissory Notes issued on March 7, 2013 to the Apollo Parties for an aggregate of approximately $6.75 million under the Termination and Release Agreement bear cash interest at an annual rate of 11% and mature on September 3, 2013.  We are required to prepay the Promissory Notes pro rata with 33% of the net cash proceeds received by us from the issuance or incurrence of any indebtedness, the issuance or sale of any equity interests, or any other financing, in each case closing after March 7, 2013.  The Promissory Notes are unsecured; provided that we may not issue any secured debt or debt that is guaranteed by any of our subsidiaries, unless, concurrently, we cause the Promissory Notes and the obligations thereunder to be equally and ratably secured by the same assets and/or guaranteed by the applicable subsidiary(ies).

Item 9.01                                           Financial Statements and Exhibits

Prospect Global Names Damon G. Barber as President and CEO

Internationally accomplished mining and finance expert brings substantial depth to the next growth phase

 Prospect Global and Apollo agree to mutual termination of previously-announced finance agreement

DENVER, CO, March 7, 2013 — Prospect Global Resources, Inc. (NASDAQ: PGRX) today announced the appointment of Damon G. Barber as President and Chief Executive Officer, effective immediately. Mr. Barber, a veteran international mining and finance executive, joined the company in December 2012 as Executive Vice President and Chief Financial Officer. Mr. Barber’s promotion brings to Prospect’s CEO office the extensive mining and finance experience necessary for its next phase of development.

Mr. Barber said: “I am extremely excited about the opportunity to lead the development of Prospect Global Resources and its Holbrook project. The fundamentals of the project and the potash mining industry are tremendous for potential value creation. I am grateful that the Board has given me this opportunity to build North America’s next potash company and mine.”

Mr. Barber has more than 20 years experience in natural-resources finance and operations and is former Chief Executive Officer of CST Mining Group Limited, a Hong Kong-based mining company. While CEO of CST, Mr. Barber led and directed the simultaneous and successful development of two copper mine development projects. The first project was developed into production, and the second project was developed to where it was sold for $505 million, approximately two times CST’s total investment in the project. During this time, Mr. Barber also served as Chairman of Marcobre S.A.C., a joint venture between CST and Korea Resources Corporation and LS Nikko.

Prior to joining CST Mining, Mr. Barber was a Managing Director at Deutsche Bank and served as the Head of Deutsche Bank’s Metals and Mining investment banking practice in Asia-Pacific.
