Exhibit 10.12

STOCKHOLDERS AGREEMENT

STOCKHOLDERS AGREEMENT dated as of January 24, 2011 by and among (i) Prospect
Global Resources Inc., a Delaware corporation (the "Company"), (ii) Richard
Merkin ("Merkin"), and (iii) the other holders of Common Stock of the Company
signatory hereto (together with Merkin, the "Stockholders").
 
Section 1. Definitions.  For purposes of this Agreement, the following terms
have the indicated meanings:
 
"Affiliate" of a person means any other person controlling, controlled by or
under common control with such person, whether by ownership of voting
securities, by contract or otherwise.
 
"Board" means the Company's Board of Directors.
 
"Common Stock" means the Company's common stock, par value $ .0001 per share.
 
"Securities Act" means the Securities Act of 1933, as amended.
 
Section 2. Board of Directors.  Each Stockholder agrees, for so long as Merkin
owns at least 1,000,000 shares of Common Stock, to vote all shares of Common
Stock over which such Stockholder and its Affiliates have voting control and to
take all other necessary or desirable actions within its control (whether as a
stockholder, director or officer of the Company or otherwise, and including,
without limitation, attendance at meetings in person or by proxy for purposes of
obtaining a quorum and execution of written consents in lieu of meetings), and
the Company shall take all necessary and desirable actions within its control
(including, without limitation, calling special board and stockholder meetings),
so that the person Merkin designates in writing from time to time to the other
Stockholders is elected to the Board.  For so long as Merkin has the right to
designate one member of the Board, and for a period of three (3) years
thereafter, the Company shall, at its sole expense, obtain customary a
directors’ and officers’ liability insurance policy.
 
Section 3. Tag Along Right.  Except in the case of any transfer to an Affiliate,
not less than 15 days prior to any proposed transfer of Common Stock, other than
the sale in one or a series of related transactions of Common Stock by any
Stockholder or its Affiliates, the transferring Stockholder (the “Initiating
Holder”) shall deliver to Merkin a written notice (the “Sale Notice”) specifying
in reasonable detail the identity of the proposed transferee(s), the number of
shares proposed to be sold, and the terms and conditions of the proposed
transfer.  Merkin may elect to participate in the transfer by delivering to the
Initiating Stockholder a written notice of such election within the 15-day
period following delivery of the Sale Notice.  If Merkin elects to participate
in such transfer, the Initiating Stockholder and Merkin will be entitled to sell
in such proposed transfer, at the same price and on the same terms (including
form of consideration), a number of shares equal to the product of (i) the
quotient determined by dividing the number of shares proposed to be sold by the
Initiating Stockholder or Merkin, as the case may be, by the number of shares
proposed to be sold by the Initiating Stockholder and Merkin, multiplied by
(ii) the total number of shares to be sold in such proposed transfer.  Merkin's
rights hereunder shall terminate upon the issuance of Common Stock in a
registered public offering under the Securities Act of 1933, as amended, with
gross proceeds to the Company of at least $10,000,000.

Section 4. Amendment and Waiver.  Except as otherwise provided herein, no
amendment of any provision of this Agreement shall be effective unless such
amendment or waiver is approved in writing by the Company, Merkin and the
holders of at least a majority of the shares of Common Stock then held by the
other Stockholders.  The failure of any party to enforce any provision of this
Agreement shall not be construed as a waiver of such provision and shall not
affect the right of such party thereafter to enforce each provision of this
Agreement in accordance with its terms.
 
Section 5. Severability.  If any provision of this Agreement is held to be
invalid, illegal or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability shall
not affect any other provision or any other jurisdiction, but this Agreement
shall be reformed, construed and enforced in such jurisdiction as if such
invalid, illegal or unenforceable provision had never been contained herein.
 
Section 6. Entire Agreement.  Except as otherwise expressly set forth herein,
this document embodies the complete agreement and understanding among the
parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
any way.
 
Section 7. Successors and Assigns.  This Agreement shall bind and inure to the
benefit of and be enforceable by the Company and the Stockholders and their
respective successors and assigns; provided, that Merkin may not assign its
right to designate a director to any transferee of Common Stock from Merkin
other than an Affiliate of Merkin without the Company's written consent.
 
Section 8. Counterparts.  This Agreement may be executed in separate
counterparts each of which shall be an original but all of which taken together
shall constitute but one instrument.
 
Section 9. Notices.  Any notice, payment, demand or communication required or
permitted to be given pursuant to this Agreement shall be in writing and shall
be (i) delivered personally, (ii) transmitted by telecopy, or (iii) delivered by
nationally recognized overnight courier service for next business day delivery,
addressed as follows, or to such other address as such person may from time to
time specify by notice to the parties hereto:
