2. Purchase Price. The “Purchase Price” for the Royalty Interests shall be $25,000.

3. Delivery of Assignments or Shares. Seller and Buyer agree that Seller will use its best efforts to cause AWP to convey any Royalty Interests not conveyed to Buyer at Closing as soon as possible after the Closing, or provide optional substitute consideration to Buyer, as follows:

(a) Seller shall be solely responsible for obtaining any consents required to make the Assignments. After Closing, Buyer shall continue to have the Share Option as provided in Section 3(e) for the period therein provided.

(b) Seller shall cause AWP to execute, acknowledge and convey to Buyer an Assignment of the State Lease ORI in each State Lease granted by the State of Arizona to AWP under each of the State Exploration Permits, as and when the State Leases are issued to AWP. Buyer shall have the option to receive substitute Royalty Interests as provided in Section 3(c) and the Share Option as provided in Section 3(e) for the period therein provided.

(c) If, at any time after the Closing date (i) the Arizona State Land Department declines to issue any State Lease to AWP with respect to any State Exploration Permit, or (ii) the Arizona State Land Department terminates any State Exploration Permit, or (iii) the Arizona State Land Department refuses to consent to the assignment of any Royalty Interests in any State Lease, or requires any reduction of or imposes any condition on such Royalty Interests as a condition of approving an assignment of such Royalty Interests or approving any royalty reduction or other action with respect to a State Lease, or (iv) if AWP has not been issued all of the State Leases and conveyed to Buyer all Royalty Interests in the entire State Leased Premises on or before March 1, 2013, Buyer shall have the option to receive substitute Royalty Interests. Buyer shall have the option to receive a substitute Assignment of additional Private Lease ORI, Mineral Interest Royalty, or State Lease ORI, or combination, in the same number of acres in portions of the Private Leased Premises, Mineral Interest Lands and State Leased Premises under State Leases issued to AWP and selected by Buyer, nearest to the affected State Lease or State Leases, in a percentage sufficient to compensate Buyer for the reduced Royalty Interests in the affected State Lease. The percentage of such additional Royalty Interests in particular AWP Interests shall be selected by Buyer. Without limiting the foregoing, if AWP has not been issued any State Leases as of the date that AWP conveys to Buyer the Private ORI under Section 3(a), at any time prior to the assignment of any portion of the State Lease ORI to Buyer, Buyer may elect to receive an Assignment of 1.388% Private Lease ORI in all of the Private Leased Premises and a 1.388% Mineral Interest Royalty in all of the Mineral Interest Lands, in substitution for its right to receive the State Lease ORI.

(d) The form of the Assignment attached as Exhibit B is drafted in contemplation of assignments of the Private Lease ORI, Mineral Interest Royalty and State Lease ORI. Because the assignments of Private Lease ORI, Mineral Interest Royalty and State Lease ORI may be made in separate instruments, Buyer may prepare a form of assignment for any particular assignment made hereunder with only the provisions from the Assignment relevant to the type of Royalty Interests assigned.

(e) If AWP fails for any reason to deliver Assignments of all of the Royalty Interests (or Assignments of any additional or substitute Royalty Interests if elected by Buyer as provided in Section 3(c)) on or before December 31, 2013 (the “Share Option Termination Date,” Buyer shall have the option exercisable at any time thereafter to elect to receive additional common shares of Seller on the same terms as under the Common Stock Purchase Agreement dated as of November 22, 2011 between Seller and Very Hungry LLC (“Share Purchase Agreement”), including the price per share, registration rights and other terms (the “Share Option”). In lieu of paying cash compensation for such shares, Buyer shall reconvey to AWP without warranty some or all of the Royalty Interests previously conveyed to Buyer (as described below) and/or relinquish its rights hereunder to some or all of the Royalty Interests not conveyed to Buyer, as elected by Buyer in the notice of exercise of the Share Option. Buyer shall have this option to acquire shares in its sole discretion, exercisable by notice to Seller at any time on or after the Share Option Termination Date (“Share Option Exercise Date”). Buyer may elect in lieu of exercising the Share Option to retain the portion of the Royalty Interests previously conveyed and to require Seller to continue to use its best efforts to cause AWP to convey the remaining Royalty Interests to Buyer, or may elect to retain all or any portion of the Royalty Interests received prior to the Share Option Exercise Date and receive shares under the Share Option for the remainder of the Royalty Interests. Buyer may elect to exercise the Share Option one or more times on or after the Closing date and prior to the Share Option Termination Date, as to any portion selected by Buyer of the Royalty Interests not timely received at Closing (or in the case of State Lease ORI, not received on or before March 1, 2013). The number of shares to which Buyer is entitled if it exercises the Share Option shall be determined by dividing the value of the Royalty Interests by the price per share under the Share Purchase Agreement. The value of the Royalty Interests for purposes of determining the number of shares shall be 1% of the fair market value of the AWP Interests (including any mine or other improvements thereon), without consideration of any encumbrance of the AWP Interests, determined as of the Share Option Exercise Date. Such fair market value shall be determined by the parties. In the event the parties are unable to agree to the fair market value within 90 days after the Share Option Exercise Date, the fair market value shall be determined by a valuation expert or appraiser with substantial experience in the potash industry, which expert shall be independent of both parties and agreed by the parties. Fees of the expert shall be split by the parties.

ADDITIONAL TERMS AND CONDITIONS

This Assignment is subject to the following terms, conditions and limitations:

1. Payments. The Royalty Interests shall be paid within 45 days of the end of each calendar quarter with respect to all Minerals sold, used or consumed, or distributed in kind by Assignor to its members in such calendar quarter. Assignor shall pay to Assignee the amounts due under the Royalty Interests by wire transfer of immediately available funds to the account of Assignee at such bank as Assignee may designate from time to time by written notice to Assignor. Any such bank shall be deemed the agent of Assignee only for the purpose of receiving payments.

2. Extent of Royalty Interests. (a) The Overriding Royalty Interests are granted subject to the terms and provisions of the Mining Leases, any amendment, renewal, substitution, or extension of the Mining Leases, or any amendments or modifications to or substitutions for the Mining Leases, or any new lease covering the Leased Premises if the new lease is taken or acquired by Assignor, its successors or assigns, whether any new lease, amendment, modification or substitution is entered into by (or in the name, or on behalf of) Assignor, or by (or in the name, or on behalf of) any parent, subsidiary, affiliated or related entity or other person associated in any manner to or with Assignor, or by any successor or assign of Assignor; provided that no such amendment, modification, renewal, substitution or extension, shall reduce, diminish or otherwise adversely affect Assignee’s Overriding Royalty Interests without Assignee’s prior written consent, which may be withheld by Assignee in its sole discretion. Nothing in the Potash Sharing Agreement, or any future amendment to the Potash Sharing Agreement, shall reduce, diminish or otherwise adversely affect Assignee’s Overriding Royalty Interests without Assignee’s prior written consent, which may be withheld by Assignee in its sole discretion.

(b) To the extent required to obtain approval of the Arizona State Land Department to any Overriding Royalty Interest in a State Lease, Assignee acknowledges that Assignee’s Overriding Royalty Interest in such State Leased Premises is subordinate to the State of Arizona’s royalty interest under such State Lease. If the Arizona State Land Department refuses to consent to the assignment of any Overriding Royalty Interest or requires any reduction of or imposes any condition on the Overriding Royalty Interest as a condition of approving an assignment of the Overriding Royalty Interests or approving any royalty reduction or other action with respect to a State Lease, Assignee shall have the remedies provided in Section 3 of the Purchase and Sale Agreement.

(c) “Gross Value” shall mean, for sales of Mineral products under arms-length contracts, a sum calculated based on tons actually sold and shipped during a calendar quarter at the actual average quarterly sales price received by Assignee during such calendar quarter on a weighted basis according to production. “Gross Value” shall mean, for all Minerals or Mineral products sold under non-arms length contracts, used or consumed, or distributed in kind by Assignor to its members, the fair market value of such Minerals or Mineral Products without deduction for any costs, expenses, liabilities or obligations paid or incurred by Assignor, other than transportation from the point of shipment to market at the mine (but not intra-mine transportation costs); provided, however, that under no circumstances may the Gross Value less transportation costs be less than the average Gross Value of the Mineral or Mineral product, f.o.b. the mine. Assignor shall obtain Assignee’s agreement (which shall not be unreasonably withheld) to the method of determining Gross Value of any Minerals or Mineral Products sold under non-arms length contracts, used or consumed, or distributed in kind by Assignor to its members, prior to commencing such use, consumption or sale.

(d) If, by reason of failure to use best mining practices or negligence on the part of Assignor, Minerals are lost or wasted, or rendered economically unrecoverable, Assignor shall be obligated to pay Assignee the Royalty Interests thereon to the same extent as if such Minerals had been mined or processed utilizing best mining practices, and settlement shall be made on the basis of independent estimates obtained by Assignee of the tonnage, grade and recovery rate of Minerals so lost, wasted or rendered economically unrecoverable.

3. Reports, Records, Audits and Inspections. (a) During every year in which there is production of ores or minerals from the Leased Premises or Mineral Interest Lands, Assignor shall deliver to Assignee copies of all exploration and production reports prepared by Assignor regarding its operations on such lands. Assignor shall also deliver to Assignee, with each royalty payment, reports detailing the amount of production subsequent to the prior report, the amount of production sold subsequent to the prior report, and the Gross Value upon which the royalty payment is based, and any other similar information reasonably requested by Assignee.

(b) Assignee and its representatives shall, at their sole risk and expense, upon reasonable advance notice to Assignor, have the right to inspect and copy all books and records used by Assignor to calculate the Royalty Interests due hereunder during normal business hours once in each calendar year (which limitation shall not apply if Assignor is in default hereunder or to access in connection with a prospective purchaser of Assignee’s interest).

(c) Assignee and its representatives shall, at their sole risk and expense, upon reasonable advance notice to Assignor, have access during normal business hours once in each calendar year (which limitation shall not apply if Assignor is in default hereunder or to access in connection with a prospective purchaser of Assignee’s interest) to all operations conducted by or on behalf of Assignors on or related to the Leased Premises or Mineral Interest Lands for the purposes of viewing or inspecting the same, provided that Assignee and its representatives shall not unreasonably interfere with such operations.

(d) Assignee, upon written notice, shall have the right to undertake, either directly or through an independent firm of certified public accountants, an audit of the records and documentation that relate to the calculation of the Royalty Interests for any calendar quarter within five years after receipt of payment of the Royalty Interests for such calendar quarter. Any calculation not so audited shall be deemed final and shall not thereafter be subject to audit or challenge, except in the case of gross negligence or fraud.

4. Mining Lease Acquisition. If Assignor or its successors or assigns should ever purchase, acquire directly or indirectly by exchange or otherwise acquire any interest in the Leased Premises owned by the lessor under any of the Mining Leases, then the Overriding Royalty Interests shall automatically convert to a perpetual, non-participating royalty interest burdening such acquired portion of the Leased Premises.

5. Further Assurances. Assignor shall obtain, at its sole cost and expense and without diminishing the Royalty Interests, any consents required from the Arizona State Land Department or the parties to the Underlying Agreements, required for the assignment of Royalty Interests hereunder. Assignor hereby covenants that from time to time it will execute additional assignments and deeds necessary to create and maintain the Royalty Interests. Separate assignments of the Overriding Royalty Interests in the State Leased Premises may be executed on officially approved forms by Assignor to Assignee, in sufficient counterparts to satisfy applicable statutory and regulatory requirements. Those assignments shall be deemed to contain all of the exceptions, reservations, warranties, rights, titles, powers and privileges set forth in this Assignment as fully as though they were set forth in each such assignment. The interests conveyed by such separate assignments are the same, and not in addition to, the interests conveyed herein.

6. Law. This Assignment shall be governed by the law of the State of Arizona and any questions arising hereunder shall be construed or determined according to such law, without regard to the conflict of laws provisions thereof. In the event that any judicial decision shall invalidate the grant of a perpetual, non-participating royalty interest or overriding royalty interest, the parties intend that the economic consequences and the contractual rights and obligations of the parties specified hereunder shall remain the same, and this Assignment shall be reformed or amended by the court or the parties to accomplish such intent.

7. Recording. The parties agree that Assignee may record this Assignment in accordance with Arizona law in the real property records of Apache County, Arizona, and in the office of the Arizona State Land Department and any other applicable office, to give notice of the interests granted herein and to obtain any required approval of the Arizona State Land Department to this Assignment.

8. Successors and Assigns. (a) This Assignment and the Royalty Interests created hereby shall run with the Leased Premises and the Mineral Interest Lands and be binding upon and inure to the benefit of Assignor and Assignee and their respective successors and assigns.

(b) The Royalty Interests shall be freely assignable and transferable by Assignee. No change or division in the ownership of the Royalty Interests, however accomplished, shall enlarge the obligations or diminish the rights of Assignor. No change or division in the ownership of the Royalty Interests shall be binding on Assignor until a copy of the instrument evidencing the change or division in ownership has been received by Assignor.

(c) Assignor may not assign or transfer all or any portion of its interest in the Leased Premises or the Mineral Interest Lands, or assign or delegate this Assignment or the obligations of Assignor hereunder, unless Assignor shall obtain from any such assignee or transferee and provide to the Assignee a written assumption in a form reasonably satisfactory to Assignee of the obligations of Assignor under this Assignment. No such transfer or assignment shall relieve Assignor of its obligations under this Assignment without the prior written consent of Assignee.

9. Representations and Warranties. Assignor represents and warrants to Assignee as follows:

(a) Assignor has all necessary corporate power and authority to execute and deliver this Assignment and to perform its obligations hereunder;

(b) This Assignment has been duly authorized by all necessary corporate or other action of Assignor and, when and as executed and delivered by Assignor, shall constitute the valid and binding agreement of Assignor, enforceable against Assignor in accordance with its terms, subject to applicable bankruptcy, insolvency and other similar laws affecting the enforceability of creditors’ rights generally, general equitable principles, and the discretion of courts in granting equitable remedies;

(c) Neither the execution or delivery of this Assignment nor its performance will violate or breach the Mining Leases or any agreement or covenant to which such Assignor is a party or by which it is bound;

(d) Assignor represents and warrants to Assignee that (i) Assignor has good and marketable title to the Mining Leases, the Leased Premises and the Mineral Interest Lands, (ii) no default, or circumstance that upon the passage or time or giving of notice would become a default, exists under any of the Mining Leases, and (iii) the Royalty Interests are free and clear of all liens, encumbrances or defects;

(e) Assignor makes to Assignee all of the representations and warranties contained in paragraph 4 of the Purchase and Sale Agreement, as of the Effective Date of this Assignment.

10. Submission to Jurisdiction; Waivers. Each of the parties hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to the enforcement of this Assignment, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of Colorado located in Denver, Colorado, the United States District Court for the District of Colorado, and appellate courts from any of the foregoing;

(b) consents that any such action or proceeding may be brought in such courts, and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail or overnight mail or courier service), postage prepaid, to such party at its address under the notice provision below; and agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law; and

(d) agrees that in the event of any dispute arising out of or relating to this Agreement, the prevailing Party shall be entitled to recover from the other Party court costs and reasonable attorneys’ fees.

11. Waiver. The failure of either Assignee or Assignor to insist on the strict performance of any provision of this Assignment or to exercise any right, power or remedy upon a breach hereof shall not constitute a waiver of any provision of this Assignment or limit Assignee’s or Assignor’s right thereafter to enforce any provision or exercise any right hereunder. A waiver of any provision of this Assignment shall not be effective unless in writing and signed by the party against whom it is to be enforced.

12. Amendment. No modification or amendment of this Agreement shall be valid unless made in writing and duly executed by Assignee and Assignor.

13. Entire Agreement. This Assignment, together with the Purchase and Sale Agreement, contains the entire understanding of Assignor and Assignees and supersedes all prior agreements and understandings between Assignor and Assignee relating to the subject matter hereof. Assignor’s representations, warranties and covenants in the Purchase and Sale Agreement shall survive the execution of this Assignment and shall not be deemed to be merged into or terminated by this Assignment.

14. Severability. If any term or other provision of this Assignment is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Assignment shall nevertheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Assignment so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

15. Notices. Any notice required or permitted by this Assignment shall be given in writing by personal service, overnight delivery service, e-mail, facsimile or by certified mail, return receipt requested, postage prepaid, as follows:
