Section 8.05 Indemnification Procedures. The party making a claim under this Article VIII is referred to as the “Indemnified Party”, and the party against whom such claims are asserted under this Article VIII is referred to as the “Indemnifying Party”.

(a) Third Party Claims. If any Indemnified Party receives notice of the assertion or commencement of any Action made or brought by any Person who is not a party to this Agreement or an Affiliate of a party to this Agreement or a Representative of the foregoing (a “Third Party Claim”) against such Indemnified Party with respect to which the Indemnifying Party is obligated to provide indemnification under this Agreement, the Indemnified Party shall give the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) calendar days after receipt of such notice of such Third Party Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party shall describe the Third Party Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. In connection with any Third Party Claim, (i) the Indemnified Party may defend with attorneys of its choice against, and consent to the entry of any order with respect to, the Third Party Claim in any manner it may reasonably deem appropriate in its reasonable discretion (provided the Indemnified Party shall consult with any Indemnifying Party in connection therewith), (ii) each Indemnifying Party will be jointly and severally obligated to reimburse the Indemnified Party promptly and periodically for the Losses relating to defending against the Third Party Claim, and (iii) each Indemnifying Party will remain jointly and severally Liable for any Losses. Seller and Buyer shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim, including making available (subject to the provisions of Section 5.06) records relating to such Third Party Claim and furnishing, without expense (other than reimbursement of actual out-of-pocket expenses) to the defending party.

(b) Settlement of Third Party Claims. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not enter into settlement of any Third Party Claim without the prior written consent of the Indemnified Party, except as provided in this Section 8.05(b). If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection with such Third Party Claim and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to that effect to the Indemnified Party. If the Indemnified Party fails to consent to such firm offer within thirty (30) days after its receipt of such notice, the Indemnified Party may continue to contest or defend such Third Party Claim. If the Indemnified Party fails to consent to such firm offer and also fails to assume defense of such Third Party Claim, the Indemnifying Party may settle the Third Party Claim upon the terms set forth in such firm offer to settle such Third Party Claim. If the

Indemnified Party has assumed the defense pursuant to Section 8.05(a), it shall not agree to any settlement without first consulting with the Indemnifying Party.

(c) Direct Claims. Any Action by an Indemnified Party on account of a Loss which does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by the Indemnified Party giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) days after the Indemnified Party becomes aware of such Direct Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have thirty (30) days after its receipt of such notice to respond in writing to such Direct Claim.

Section 8.06 Tax Treatment of Indemnification Payments. All indemnification payments made under this Agreement shall be treated by the Parties as an adjustment to the Purchase Price for tax purposes, unless otherwise required by Law.

Re:	AWP Explorations Permits in 00X 00X xxx 00X 00X

Xxxxxxxxx,

As you aware, HNZ has appealed two of AWP’s state exploration permits which were obtained by the Karlsson Group prior to the formation of AWP. HNZ cites that that AWP does not have access to the following sections:

AWP Exploration Permit		T-R-S
115058		16N 25E 16
115059		16N 25E 32

Extensive legal discussions with the ASLD have exhausted all reasonable remedies and we’ve subsequently learned that the ASLD will deny AWP’s renewal of these exploration permits. We’ve also learned that HNZ has appealed numerous state exploration permits held by Passport and HNZ plans to appeal the following two additional AWP sections that also lack access and are not contiguous with the bulk of our acreage:

AWP Exploration Permit		T-R-S
114503		16N 24E 2
114325		16N 24E 14

HNZ is willing to grant AWP a 4% royalty in exchange for the exploration permits on these sections. We believe this is an optimal outcome due to:

a) None of the sections are contiguous with AWP acreage and no potash resource underlying these sections was included in AWP’s 43-101 or PEA

b) AWP would have no ongoing financial liability and this structure preserves cash

c) Without this structure, AWP will lose these sections

Please respond by 2pm MDT on Monday, April 9, 2012 if you approve AWP entering into this agreement.

Trustor is the lawful owner of good and marketable title to the Trust Property. Trustor has the full right, power, and authority, acting alone, to execute and deliver this Deed of Trust to Lender. Part V of Exhibit A describes all easements, rights-of-way, royalty interests and miscellaneous real property interests owned by Trustor related to the Trust Property. The Trust Property is free and clear of all liens and encumbrances other than Permitted Liens (defined below). Subject to the exception in the preceding sentence, Trustor warrants and will forever defend the title to the Trust Property against the lawful claims of all persons.

Trustor may be the nominal party in such proceeding, but Lender shall be entitled to participate in the proceeding and to be represented in the proceeding by counsel of Lender’s own choice. Trustor will deliver, or cause to be delivered, to Lender such instruments as Lender may request from time to time to permit such participation.

2.2.2 Payment of Taxes. Trustor shall cause to be paid when due (and in all events prior to delinquency) all Lands taxes and assessments, payroll taxes, sales and use taxes, personal property taxes, special taxes, assessments, water charges and sewer service charges levied against or on account of the Trust Property or this Deed of Trust (collectively, “Taxes”), and shall pay when due all claims for work done on or for services rendered or material furnished to the Trust Property.

Trustor shall have the right before any delinquency occurs to contest or object to the amount or validity of any Taxes by appropriate proceedings, but this shall not be deemed or construed in any way as relieving, modifying, or extending Trustor’s covenant to pay any such Taxes at the time and in the manner provided in this section, unless Trustor has given prior written notice to Lender of Trustor’s intent to so contest or object to any Taxes, and unless, in Lender’s reasonable discretion, (i) Trustor shall demonstrate to Lender’s satisfaction that the proceedings to be initiated by Trustor shall conclusively operate to prevent the sale of the Trust Property or any part thereof or interest therein to satisfy such Taxes prior to final determination of such proceedings, (ii) Trustor shall furnish a good and sufficient bond or surety as requested by and satisfactory to Lender, or (iii) Trustor shall demonstrate to Lender’s satisfaction that Trustor has provided a good and sufficient undertaking as may be required or permitted by law to accomplish a stay of any such sale.

2.2.3 Effect of New Taxation or Changes in Law Regarding Taxation. If, by the laws of the United States of America, or of any state, tribal or other governmental authority having jurisdiction over Trustor or the Trust Property, any tax, assessment or governmental charge of any character whatever is due or becomes due on account of this Deed of Trust or the Indebtedness secured hereby, except for income or franchise taxes of Lender, Trustor covenants and agrees to pay any such tax, assessment or governmental charge of any character whatever in the manner required by any such law when the same shall become due. Trustor further covenants to hold harmless and agrees to indemnify the Lender, its successors or assigns, for, from and against any liability incurred by reason of the imposition of any such tax, assessment or government charge on account of this Deed of Trust or the Indebtedness secured hereby. If any tax to which this Section 2.2.3 applies is enacted subsequent to the date of this Deed of Trust, this event shall have the same effect as an Event of Default, and Lender may exercise any or all of its available remedies for an Event of Default as provided below unless Trustor either pays or causes the tax to be paid before it becomes delinquent or contests the tax as provided below in Section 2.8 and deposits with Lender cash or a sufficient corporate surety bond or other security satisfactory to Lender; provided, however, that if in the opinion of counsel for the Lender: (a) it might be unlawful to require Trustor to make such payment; or (b) the making of such payment might result in the imposition of interest beyond the maximum amount permitted by law, then the Lender may elect, by notice in writing given to the Trustor, to declare all of the Indebtedness

secured hereby to be and become due and payable thirty (30) days from the giving of such notice.

2.3 Maintenance of Trust Property. Trustor will not do or permit to be done to, in, upon or about any portion of the Trust Property, anything that may in any manner impair the value thereof, or weaken, diminish or impair the security of this Deed of Trust. In furtherance of the foregoing, Trustor’s possession and use of the Trust Property shall be governed by the following:

2.3.3 Trustor shall maintain in full force and effect the Mineral Leases and Mineral Permits and make payments required by and perform and comply with all material terms, provisions, covenants, conditions and agreements imposed upon or assumed by Trustor under any of the Mineral Leases or Mineral Permits, including amendments and supplements thereto.

2.3.4 Trustor shall promptly notify Lender in writing of the receipt by Trustor of any notice from Lessor under either the Mineral Leases or the Mineral Permits claiming any default by Trustor in the performance or observance of any of the terms, covenants or conditions on the part of Trustor to be performed or observed, and promptly cause a copy of each such notice received by Trustor to be delivered to Lender.

2.3.5 Trustor shall furnish to Lender, 30 days prior to the due date, proof of payment of all renewal fees and proof of amount expended for exploration work under the Mineral Permits.

2.3.6 Trustor shall execute and deliver, upon request of Lender, such instruments as Lender may deem useful or required to permit Lender to cure any default under each of the Mineral Leases and the Mineral Permits or permit Lender to take such other action as Lender considers desirable to cure any such default and preserve the interest of Lender in the Trust Property.

2.3.7 Trustor shall, at Trustor’s own expense, (i) keep in full force and effect all licenses, permits, rights-of-way, easements and privileges necessary or appropriate for the proper use and operation of the Trust Property, by the proper payment of all rentals, royalties and other

sums due thereunder and the proper performance of all obligations and other acts required thereunder; (ii) cause the Trust Property to be properly maintained, developed and continuously operated for the production of Minerals and protected against erosion or damage in a good and workmanlike manner as a prudent operator would in accordance with good field practice and applicable federal, state, tribal and local laws, rules, regulations and orders; (iii) pay or cause to be paid when due all expenses incurred in connection with such maintenance, development, operation and protection of the Trust Property; (iv) keep all goods, including equipment, inventory and fixtures included in the Trust Property in good and effective repair, working order and operating condition and make all repairs, renewals, replacements, substitutions, additions and improvements thereto and thereof as are necessary and proper; (v) permit Lender, and its respective agents, employees, contractors, designees and consultants, to enter upon the Trust Property during normal business hours and with reasonable advance notice for the purpose of investigating and inspecting the condition and operation of the Trust Property, and do all things necessary or proper to enable Lender to exercise this right whenever Lender so desires; and (vi) do all other things necessary to keep unimpaired Lender’s interests in the Trust Property.

2.4 Nuisance, Waste. Trustor shall not cause, conduct or permit any nuisance nor commit, permit, or suffer any stripping of or waste on or to the Trust Property or any portion of the Trust Property.

2.5 Removal of Improvements. Trustor shall not demolish or remove any Improvements from the Lands without Lender’s prior written consent. As a condition to the removal of any Improvements, Lender may require Trustor to make arrangements satisfactory to Lender to replace such Improvements with Improvements of at least equal value.

2.6 Restoration. Trustor shall promptly repair, restore or rebuild any Improvements now or hereafter on the Lands which may become damaged or be destroyed by any cause whatsoever (excluding minor inconsequential damage costing less than Fifty Thousand Dollars ($50,000.00) to repair which does not materially impair the value or utility of the Improvements), so that upon completion of the repair, restoration and rebuilding of said Improvements there will not be any liens of any nature arising out of said repair, restoration and rebuilding, and the Trust Property will have a commercial value at least as great as the commercial value of the Trust Property prior to such damage or destruction.

2.7 Lender’s Right to Enter. Trustor shall permit Lender to enter the Lands and Improvements at any time upon reasonable advance notice (except in the event of an emergency in which case no notice shall be required), during normal business hours (except in the event of an emergency in which case Lender may enter at any time), and in a manner that does not unreasonably interrupt Trustor’s use and enjoyment of the same for the purpose of inspecting Trustor’s compliance with the terms and provisions of this Deed of Trust.

2.8 Compliance with Governmental Requirements. Trustor warrants that the Trust Property and Trustor’s use of the Trust Property comply with all applicable laws, ordinances, and regulations, now or hereafter in effect, of all governmental authorities, including without limitation, building and zoning ordinances, and Environmental Laws (collectively, “Legal

Requirements”). Trustor shall promptly comply with all Legal Requirements applicable to the Trust Property or Trustor. Trustor may contest in good faith any Legal Requirement and withhold compliance during any proceeding, including appropriate appeals, so long as Trustor has notified Lender in writing prior to doing so and so long as, in Lender’s sole opinion, Lender’s interest in the Trust Property are not jeopardized. Lender may require Trustor to post adequate security or a surety bond, reasonably satisfactory to Lender, to protect Lender’s interest.

2.9 No Encumbrances. Trustor shall not directly or indirectly, without Lender’s prior written consent, create, incur, permit to exist or assume any mortgage, deed of trust, pledge or other lien or claim for lien or encumbrance upon the Trust Property or any part thereto other than the Permitted Liens. In the event of the creation, incurrence or existence of any such lien, claim for lien or encumbrance, Trustor shall cause the same to be satisfied or removed, or shall bond over the same to Lender’s satisfaction within ninety (90) days of the creation, incurrence or attachment thereof to the Trust Property.

Trustor shall promptly notify Lender in writing of: (a) any loss or damage to any part of the Trust Property that exceeds Fifty Thousand Dollars ($50,000.00) in any single instance; (b) any material change, whether contemplated, pending or final, in the assessment of any part of Trust Property by taxing authorities or in the zoning classification; (c) the actual or threatened commencement of any proceedings under condemnation or eminent domain affecting any part of the Trust Property, including those proceedings relating to severance and consequential damage and change in grade of streets, copies of any and all papers served in connection with any such proceedings to be delivered to Lender upon such service; and (d) any other action, whether contemplated (when known to Trustor), pending or final, by any public authority or otherwise, that could affect the value of any part of the Trust Property.

2.11 Changes. Trustor shall not suffer or permit any change in the general nature of the occupancy of the Trust Property, without the prior written consent of Lender.

2.12 Entry by Lender; Adverse Possession. Trustor shall permit Lender to enter the Trust Property at any time upon reasonable advance notice (except in the event of an emergency in which case no notice shall be required), during normal business hours (except in the event of an emergency in which case Lender may enter at any time), and in a manner that does not unreasonably interrupt Trustor’s use and enjoyment of the Trust Property for the purpose of inspecting Trustor’s compliance with the terms and provisions of this Deed of Trust. Trustor shall not make or permit any use of the Trust Property that could with the passage of time result in the creation of any right of user, or any claim of adverse possession or easement on, to or against any part of the Trust Property in favor of any person or the public.

2.13 Subleases. Trustor shall not enter into any sublease, license, or assignment of its rights under the Mineral Leases or Mineral Permits (or any binding letter of intent or binding term sheet with respect thereto) without obtaining the prior written consent of Lender, including, but not limited to, Lender’s approval of the proposed tenant, the proposed guarantor, if any, rental rate, term, the form of the proposed agreement, and the financial statements of the proposed tenant and the proposed guarantor, if required by Lender.

2.14 Environmental Matters. Trustor shall pay and perform all of its obligations arising under the Environmental Indemnity Agreement.

2.15 Insurance. Trustor shall procure and maintain policies of the insurance with standard extended coverage endorsements on a replacement basis for the full insurable value covering all structures and fixtures erected or installed upon the Property and all equipment operated or located upon the Property in an amount sufficient to avoid application of any coinsurance clause, and with a standard Mortgagee clause in favor of Lender, and a standard Lender Loss Payee clause in favor of Lender. Trustor shall also procure and maintain comprehensive general liability insurance in such coverage amounts as Lender may request, but in any event in an amount of at least Two Million Dollars ($2,000,000.00) per occurrence, with Lender being named as additional insured in such liability insurance policies. Additionally, Trustor shall maintain such other insurance, including but not limited to hazard and business interruption insurance as Lender may require. Policies shall be written by such insurance companies and in such form as may be reasonably acceptable to Lender. Trustor shall deliver to Lender certificates of coverage from each insurer that provide that coverage will not be cancelled or diminished without a minimum of thirty (30) days’ prior written notice to Lender, that there will be no cancellation due to non-payment of premiums without a minimum of ten (10) days’ prior written notice to Lender, and not containing any disclaimer of the insurer’s liability for failure to give such notice. Each insurance policy also shall include an endorsement providing that coverage in favor of Lender will not be impaired in any way by any act, omission or default of Trustor or any other person. Upon request of Lender (however, not more than once a year) Trustor shall furnish to Lender a report on each existing policy of insurance showing: (a) the name of the insurer; (b) the risks insured; (c) the amount of the policy; (d) the property insured, the then current replacement value of such property, and the manner of determining that value; and (e) the expiration date of the policy. Trustor shall, upon request of Lender, have an independent appraiser satisfactory to Lender determine the cash value replacement cost of the Trust Property.

Unless Trustor provides Lender with evidence of the insurance coverage required hereunder at least thirty (30) days before the expiration of any existing policy or policies, with evidence of premium paid, Lender may purchase insurance at Trustor’s expense to protect Lender’s interests in the Trust Property. The insurance may, but need not, protect Trustor’s interests. The coverage that Lender purchases may not pay any claim that Trustor makes or any claim that is made against Trustor in connection with the collateral. Trustor may later cancel any insurance purchased by Lender, but only after providing Lender with evidence that Trustor has obtained insurance as required by their agreement. If Lender purchases insurance, Trustor shall be responsible for the costs of that insurance, including interest and any other charges Lender may impose in connection with the placement of the insurance, until the effective date of the cancellation or expiration of the insurance. The costs of the insurance may be added to Trustor’s total outstanding balance or obligation. The costs of the insurance purchased by Lender may be more than the cost of the insurance Trustor may be able to obtain.

2.16 Application of Proceeds of Insurance. Trustor shall promptly notify Lender of any loss or damage to the Trust Property. Lender may make proof of loss if Trustor fails to do so within fifteen (15) days of the casualty. Whether or not Lender’s security is impaired, Lender

may, at Lender’s election, receive and retain the proceeds of any insurance and apply the proceeds to the reduction of the Indebtedness, payment of any lien affecting the Trust Property, or the restoration and repair of the Trust Property. If Lender elects to apply the proceeds to restoration and repair, Trustor shall repair or replace the damaged or destroyed Improvements in a manner satisfactory to Lender. Lender shall, upon satisfactory proof of such expenditure, pay or reimburse Trustor from the proceeds for the reasonable cost of repair or restoration if Trustor is not in default under this Deed of Trust. Any proceeds which have not been disbursed within one hundred eighty (180) days after their receipt and which Lender has not committed to the repair or restoration of the Trust Property shall be used first to pay any amount owing to Lender under this Deed of Trust, then to pay accrued interest, and the remainder, if any, shall be applied to the principal balance of the Indebtedness. If Lender holds any proceeds after payment in full of the Indebtedness, such proceeds shall be paid to Trustor as Trustor’s interests may appear.

2.17 Condemnation. If any proceeding in condemnation is commenced, Trustor shall promptly notify Lender in writing, and Trustor shall promptly take such steps as may be necessary to defend the action and obtain the award. Trustor may be nominal party in such proceeding, but Lender shall be entitled to participate in the proceeding and to be represented in the proceeding by counsel of its own choice. Trustor will deliver or cause to be delivered to Lender such instruments and documentation as may be required by Lender from time to time to permit such participation. If all or any part of the Trust Property is condemned by eminent domain proceedings or by any proceeding or purchase in lieu of condemnation, or if all or any part of the Trust Property is sold in lieu of condemnation, Lender may at its election require that all or any portion of the net proceeds of the award or sale be applied to the Indebtedness or the repair or restoration of the Trust Property. If Lender requires that all or any portion of the net proceeds of the award or sale be applied to the repair or restoration of the Trust Property, and if the net proceeds of the award or sale are insufficient to cover the cost of rebuilding or restoration, Trustor shall pay such cost in excess of the net proceeds of the award before being entitled to any reimbursement out of such net proceeds. Any surplus which may remain out of such net proceeds after payment of such cost of rebuilding or restoration shall, at the option of Lender, be applied on account of the Indebtedness or be paid to any other party entitled thereto. In any event, so long as any portion of the Indebtedness remains unpaid, Trustor shall commence rebuilding or restoration of any remaining portion of the Trust Property promptly after the taking and shall diligently pursue the same to completion. The net proceeds of the award or sale shall mean the award or sale after payment of all reasonable costs, expenses, and attorneys’ fees incurred by Lender in connection with the applicable condemnation or sale in lieu of condemnation.

2.18 Imposition of Fees and Charges by Governmental Authorities. Upon request by Lender, Trustor shall execute such documents in addition to this Deed of Trust and take such other actions as requested by Lender to perfect and continue Lender’s Deed of Trust interest in the Real Property and lien on any other Trust Property. Trustor shall reimburse Lender for all expenses incurred in recording, perfecting or continuing this Deed of Trust, including without limitation all taxes, fees, documentary stamps, and other charges for recording or registering this Deed of Trust.

2.19 Hold Harmless. Trustor shall indemnify and hold Lender harmless for, from and against all loss, liability, damages, costs and expenses, including reasonable attorney’s fees,

incurred by reason of any action, suit, proceeding, hearing, motion or application before any Court or administrative body in and to which Lender may be or become a party by reason hereof, including but not limited to condemnation, bankruptcy, probate and administrative proceedings, as well as any other of the foregoing wherein proof of claim is by law required to be filed or in which it becomes necessary to defend or uphold the terms of and the lien created by this Deed of Trust, unless caused by the malicious act or omission or gross negligence of Lender, and all money paid or expended by Lender in that regard, together with interest thereon from date of such payment at the rate set forth in the Note shall be so much additional Indebtedness secured hereby and shall be immediately and without notice due and payable to Lender.

2.20 Lender’s Performance and Expenditures. If any action or proceeding is commenced that would materially affect Lender’s interest in the Trust Property or if Trustor fails to comply with any provision of this Deed of Trust or any Loan Documents, including but not limited to Trustor’s failure to discharge or pay when due any amounts Trustor is required to discharge or pay under this Deed of Trust or any Loan Documents, Lender on Trustor’s behalf may (but shall not be obligated to) take any action that Lender deems appropriate, including but not limited to discharging or paying all taxes, liens, security interests, encumbrances and other claims, at any time levied or placed on the Trust Property and paying all costs for insuring, maintaining and preserving the Trust Property. Lender shall give Trustor at least ten (10) days’ prior written notice of its intent to do so; provided, however, that if failure to pay such obligation within ten (10) days shall result in an impairment of any of the Trust Property or the Lender’s secured interest and lien therein, no such notice shall be required. All such expenditures incurred or paid by Lender for such purposes will then bear interest at the rate charged under the Note from the date incurred or paid by Lender to the date of repayment by Trustor. All such expenses will become a part of the Indebtedness and, at Lender’s option, will: (a) be payable on demand; (b) be added to the balance of the Note and be apportioned among and be payable with any installment payments to become due during either: (i) the term of any applicable insurance policy; or (ii) the remaining term of the Note; or (c) be treated as a balloon payment which will be due and payable upon the maturity of the Note. This Deed of Trust also secures payments of such amounts. Such rights shall be in addition to all other rights and remedies to which Lender may be entitled upon the occurrence of an Event of Default.

2.21 Lender’s Reliance in Making Payments. Lender, in making any payment herein and as hereby authorized: (a) relating to Taxes, may do so according to any xxxx, statement or estimate procured from the appropriate public office without inquiry into the validity or accuracy thereof; and (b) relating to any prior lien or title or claim thereof, may do so without inquiry as to the validity or amount of any such prior lien or title or claim which may be asserted; and (c) may do so whenever, in its sole judgment, such payment or payments shall seem necessary or desirable to protect the security created by this Deed of Trust; provided, however, that in connection with any such payment as aforesaid, Lender, at its option, may and is hereby authorized to obtain a continuation report of title prepared by a title insurance company, the expense of which shall be repayable by the Trustor upon demand and shall be secured hereby.

2.22 Acknowledgment by Trustor. Trustor, within fifteen (15) days after Lender’s request, shall furnish a written statement, duly acknowledged, of the amount due upon this Deed of Trust and whether any alleged offsets or defenses exist against the Indebtedness secured by this Deed of Trust.

2.23 Books and Records To Be Kept by Trustor. Trustor will keep accurate books and records in accordance with generally accepted accounting principles consistently applied in which full, true and correct entries shall be promptly made as to all operations on or relative to the Trust Property, and will permit all such books or records to be inspected by Lender and/or its duly authorized representatives at all times during reasonable business hours and if, and as often as, reasonably requested by Lender, Trustor will make reports of operations in such form as Lender prescribes, setting out full data as to the Rents and any other revenues of the Trust Property.

2.23.1 Recording and Filing.

(a) Trustor shall (i) promptly and at Trustor’s own expense, record or file (or cooperate with Lender in its recording or filing) in such offices, at such times and as often as may be necessary, this Deed of Trust and every other instrument in addition or supplemental hereto, including applicable financing statements, as may be necessary to create, perfect, maintain and preserve the first priority of the liens and security interests intended to be created hereby and the rights and remedies of Lender hereunder, (ii) promptly furnish to Lender evidence satisfactory to Lender of all such recordings and filings; and (iii) otherwise do all things necessary or expedient to be done effectively to create, perfect, maintain and preserve the liens and security interests intended to be created hereby as first liens.

(b) Trustor hereby authorizes Lender, at any time and from time to time, to file any initial financing statements, amendments thereto and continuation statements with or without signature of Trustor as authorized by applicable law, as applicable to the Trust Property. Trustor hereby authorizes Lender to file financing statements with the applicable financing office describing the collateral therein as “All assets of Trustor.” For purposes of such filings, Trustor agrees to furnish any information requested by Lender promptly upon request by Lender. Trustor also ratifies its authorization for Lender to have filed any like initial financing statements, amendments thereto or continuation statements if filed prior to the date of this Deed of Trust. Trustor hereby irrevocably constitutes and appoints Lender and any officer or agent of Lender, with full power of substitution, as its true and lawful attorneys-in-fact with full irrevocable power and authority in the place and stead of Trustor or in Trustor’s own name to execute in Trustor’s name any such documents and to otherwise carry out the purposes of this Subsection, to the extent that Trustor’s authorization above is not sufficient. To the extent permitted by law, Trustor hereby ratifies all acts said attorneys-in-fact shall lawfully do, have done in the past or cause to be done in the future by virtue hereof.

2.24 Notification of Breach. Trustor shall promptly notify Lender in writing, not later than five (5) Business Days after any manager of Trustor has knowledge thereof (i) if any representation or warranty of Trustor contained in this Deed of Trust is discovered to be or becomes untrue, or (ii) Trustor fails to perform or comply with any covenant or agreement contained in this Deed of Trust or it is reasonably anticipated that Trustor will be unable to perform or comply with any covenant or agreement contained in this Deed of Trust. Trustor shall cause all the representations and warranties of Trustor contained in this Deed of Trust to be true and correct in all material respects from time to time and all times.

2.25 Defense of Title. If the title or interest of Trustor or Lender to the Trust Property or any part thereof, or the lien or encumbrance created by this Deed of Trust, or the rights or powers of Lender hereunder, shall be attacked, either directly or indirectly, or if any legal proceedings are commenced against Trustor or the Trust Property, Trustor shall promptly give written notice thereof to Lender and at Trustor’s own expense shall take all reasonable steps diligently to defend against any such attack or proceedings, employing attorneys acceptable to Lender. Lender may take such independent action in connection therewith as it may in its discretion deem advisable, and all costs and expenses, including without limitation, reasonable attorneys’ fees and legal expenses, incurred by or on behalf of Lender in connection therewith shall be a demand obligation owing by Trustor to Lender and shall bear interest at the Default Rate from the date incurred until paid, and shall constitute a part of the Obligations and be indebtedness secured and evidenced by this Deed of Trust.

2.26 Change in Structure. Trustor shall not cause or permit any change to be made in its name, address, organizational identity number, or state of organization, unless Trustor shall have notified Lender of such change at least thirty days prior to the effective date of such change, and shall have first taken all action required by Lender for the purpose of further perfecting or protecting the security interest in favor of Lender in the Trust Property. In any notice furnished pursuant to this Subsection, Trustor shall expressly state that the notice is required by this Deed of Trust and contains facts that may require additional filings of financing statements or other notices for the purposes of continuing perfection of Lender’s security interest in the Trust Property.

2.27 Further Assurances. Trustor shall execute, acknowledge and deliver, or cause to be executed, acknowledged or delivered, to Lender such other and further instruments and do such other acts as in the reasonable opinion of Lender may be necessary or desirable to effect the intent of this Deed of Trust, promptly upon request of Lender and at Trustor’s expense.

ARTICLE 3

ASSIGNMENT OF PRODUCTION AND PROCEEDS OF PRODUCTION

3.1 Assignment. Pursuant to Section 1.2, the Granting Clause, of this Deed of Trust, Lender is absolutely assigned and entitled to receive all of the severed and extracted Minerals produced from or allocated or attributed to all of the Trust Property (the “Production”), together with all of the Proceeds of Production. Trustor acknowledges and agrees that said assignment is intended to be an absolute and unconditional assignment and not merely a pledge of or creation of a security interest or an assignment as additional security. Trustor shall execute, acknowledge and deliver or cause to be executed, acknowledged and delivered, transfer orders or letters-in-lieu thereof directing all purchasers of all or any part of the Production to make payments directly to Lender and all parties to any Subleases to pay all Rents to Lender. All parties purchasing, receiving or having in their possession any of the Production or Proceeds of Production are hereby authorized and directed by Trustor to treat and regard Lender as the party entitled in Trustor’s place and stead to receive the Production and all Proceeds of Production; and said parties shall be fully protected in so treating and regarding Lender and shall be under no obligation to see to the application by Lender of any amounts received by it. Except when there is any uncured Event of Default (defined below) Trustor may deal with the Production in the

ordinary course of business and Lender grants Trustor a revocable license to receive all Proceeds of Production until such time as Lender shall have made written demand therefor. Such election by Lender shall not in any way waive the right of Lender to demand and receive the Production and all Proceeds of Production and shall not in any way diminish the absolute and unconditional right of Lender to receive the Production and all Proceeds of Production and other cash proceeds, if any, not theretofore expended by or distributed to Trustor. Any Production in the custody of Trustor shall constitute trust property for the benefit of Lender and all Proceeds of Production received by Trustor shall, when received, constitute trust funds in Trustor’s hands and shall be held by Trustor for the benefit of Lender. Trustor hereby agrees that upon the occurrence of any Event of Default or which upon the giving (or receiving) of notice or lapse of time, or both, would constitute such an Event of Default, all cash, proceeds, instruments and other property, of whatever kind or character, received by Trustor on account of the Trust Property, whether received by Trustor in the exercise of its collection rights hereunder or otherwise, shall, in accordance with instructions then given by Lender, be remitted to Lender or deposited to an account designated by Lender, in the form received (properly assigned or endorsed to the order of Lender or for collection and in accordance with Lender’s instructions) not later than the first banking business day following the day of receipt, to be applied as provided in Section 3.2 hereof and, until so applied, may be held by Lender in a separate account on which Trustor may not draw. Trustor agrees not to commingle any such property, following the receipt of any such demand from Lender or the occurrence of an Event of Default, with any of its other funds or property and agrees to hold the same upon an express trust for Lender until remitted to Lender.

3.2 Application of Proceeds. Lender shall apply all of the proceeds received pursuant to Section 3.1 hereof as provided in the Loan Documents, unless otherwise agreed to by Lender and Trustor.

3.3 No Liability in Lender. Lender is hereby absolved from all liability for failure to enforce collection of any Proceeds of Production and from all other responsibility in connection therewith, except the responsibility to account to Trustor for proceeds actually received.

3.4 Indemnity. Trustor shall indemnify Lender against all claims, actions, liabilities, judgments, costs, reasonable attorneys’ fees or other charges of every kind or nature (“Claims”) made against or incurred by Lender as a consequence of the assertion, either before or after the payment in full of the Obligations, that Lender received Production or Proceeds of Production pursuant to this Article 3 which were claimed by third persons. Lender shall have the right to employ attorneys and to defend against any Claims, and unless furnished with reasonable indemnity, Lender shall have the right to pay or compromise and adjust all Claims. Trustor shall indemnify and pay to Lender all such amounts as may be paid with respect thereto or as may be successfully adjudicated against Lender, and such amounts shall be a demand obligation owing by Trustor to Lender and shall bear interest at the Default Rate from the date incurred until paid, and shall constitute a part of the Obligations and be Indebtedness secured and evidenced by this Deed of Trust. The liabilities of Trustor as set forth in this Section 3.5 shall survive the payment or satisfaction of the Obligations and the release, reconveyance, foreclosure or other termination of this Deed of Trust.

3.5 Rights of Lender. Subject to the provisions of the Loan Documents, Lender shall have the immediate and continuing right to demand, collect, receive and receipt for all Proceeds

of Production and other payments assigned hereunder, and Lender is hereby appointed agent and attorney-in-fact of Trustor for the purpose of executing any release, receipt, division order, transfer order, relinquishment or other instrument that Lender deems necessary in order for Lender to collect and receive such payments. In addition, Trustor agrees that, upon the request of Lender, it will promptly execute and deliver to Lender such transfer orders, payment orders, division orders and other instruments as Lender may deem necessary, convenient or appropriate in connection with the payment and delivery directly to Lender of all Proceeds of Production and other payments assigned hereunder. Trustor hereby authorizes and directs that, upon the request of Lender, all purchasers, transporters and other parties now or hereafter purchasing any of the Minerals or any other interest of Trustor (whether now owned or hereafter acquired by operation of law or otherwise), in, to or relating to the Lands or to any of the estates, property, rights or other interests included in the Trust Property, or any part thereof, or now or hereafter having in their possession or control any production from or allocated to the Trust Property or any other interest of Trustor (whether now owned or hereafter acquired by operation of law or otherwise), in, to or relating to the Trust Property, or any part thereof, or the proceeds therefrom, or now or hereafter otherwise owing monies to Trustor under contracts and agreements herein assigned, shall, until Lender directs otherwise, pay and deliver such proceeds, production or amounts directly to Lender at Lender’s address set forth in the introduction to this Deed of Trust, or in such other manner as Lender may direct such parties in writing, and this authorization shall continue until the assignment of Production and Proceeds of Production and other payments contained herein is released and reassigned. Trustor agrees that all division orders, transfer orders, receipts and other instruments that Lender may from time to time execute and deliver for the purpose of collecting and receipting for such Proceeds of Production or other payments may be relied upon in all respects, and that the same shall be binding upon Trustor and its successors and assigns. No payor making payments to Lender at its request under the assignment of Proceeds of Production and other payments contained herein shall have any responsibility to see to the application of any of such funds, and any party paying or delivering Proceeds of Production or other amounts to Lender under such assignments shall be released thereby from any and all liability to Trustor to the full extent and amount of all payments, Proceeds of Production and other payments so delivered. Trustor agrees to indemnify and hold harmless any and all parties making payments to Lender, at the request of the Lender under the assignment of Production and Proceeds of Production contained herein, against any and all liabilities, actions, claims, judgments, costs, charges and attorneys’ fees and legal expenses resulting from the delivery of such payments to Lender. Should Lender bring suit against any third party for collection of any amounts or sums included within the assignment of Production and Proceeds of Production contained herein (and Lender shall have the right to bring any such suit), it may xxx either in its own name or in the name of Trustor, or both.

3.6 Designation of New Purchaser(s). Should any purchaser taking any Production from the Trust Property or any other interest of Trustor (whether now owned or hereafter acquired by operation of law or otherwise), in, to or relating to the Trust Property, or any part thereof, fail to make any payment promptly to Lender, in accordance with this assignment, then Lender, to the fullest extent permissible under applicable law, shall have the right to designate another purchaser with whom a new transaction may be made, without any liability on the part of Lender in making such designation; and failure of Trustor to consent to and promptly effect such change of purchaser shall constitute an Event of Default under Article 5 below.

3.7 No Delegation or Assumption. Nothing in this Deed of Trust shall be deemed or construed to create a delegation to or assumption by Lender, of the duties and obligations of Trustor under any agreement or contract relating to the Trust Property or any portion thereof, and all of the parties to any such contract shall continue to look to Trustor for performance of all covenants and other obligations and the satisfaction of all representations, warranties, covenants, indemnities and other agreements of Trustor thereunder, notwithstanding the assignment of production and proceeds contained herein or the exercise by Lender, prior to foreclosure, of any of its rights hereunder or under applicable law.

3.8 Cumulative. This assignment of Production and Proceeds of Production shall not be construed to limit in any way the other rights and remedies of Lender hereunder, including without limitation, its right to accelerate the indebtedness evidenced by the Obligations upon an Event of Default and the other rights and remedies herein conferred, conferred in the other documents and instruments evidencing, securing or relating to the Obligations, or conferred by operation of law.

ARTICLE 4

CHANGE IN OWNERSHIP OR OTHER TRANSFERS

Lender may, at Lender’s option, declare immediately due and payable all sums secured by this Deed of Trust upon the sale, assignment or transfer, without Lender’s prior written consent (which may be withheld or conditioned in Lender’s sole and absolute discretion), of all or any part of the Lands or any interest in the Lands. A “sale, assignment or transfer” means the conveyance of the Lands or any right, title or interest in the Lands; whether legal, beneficial or equitable; whether voluntary or involuntary; whether by outright sale, deed, installment sale contract, land contract, contract for deed, lease-option contract, or by sale, assignment, or transfer of any beneficial interest in or to any land trust holding title to the Lands, or by any other method of conveyance of an interest in the Lands.

ARTICLE 5

DEFAULT

5.1 Events of Default. The occurrence of any one of the following shall be an event of default under this Deed of Trust (“Event of Default”):

5.1.1 Default Under Note or Other Loan Documents. An Event of Default occurs under the Note or any of the other Loan Documents (subject to any applicable notice, grace or cure period provided for therein);

5.1.2 Mineral Leases. The applicable Lessor declares a breach or default by Trustor as lessee under the Mineral Leases;

5.1.3 Mineral Permits. Any Mineral Permit has been terminated or revoked;

5.1.4 Nonperformance of Covenants. Any covenant, agreement or condition of this Deed of Trust (other than covenants otherwise addressed in another clause of this Section 5.1) is not fully and timely performed, observed or kept, and such failure is not cured within thirty (30) calendar days after notice (unless a shorter cure period or no cure period is specified);

5.1.5 Transfer of the Trust Property. Any sale, assignment or transfer occurs with respect to all or any part of the Trust Property or Lessee’s Interest, except as allowed in Article 4; and

5.1.6 Other Events. Any other Default or Event of Default occurs under any other agreement for which this Deed of Trust serves as security;

and an Event of Default under this Deed of Trust shall constitute an Event of Default under all of the other Loan Documents. Nothing herein or in any other Loan Document shall operate or be construed to add on or make cumulative any cure or grace periods specified in any of the Loan Documents.

ARTICLE 6

REMEDIES

Acceleration of Indebtedness Upon Default. Upon the occurrence of an Event of Default, the whole Indebtedness secured hereby shall, at the option of Lender, and without notice, become immediately due and payable with reasonable attorneys’ fees, and thereupon, or at any time during the existence of any such default, Lender may proceed to foreclose this Deed of Trust as provided by law, anything hereinbefore or in any of the Loan Documents to the contrary notwithstanding and/or exercise any other right or remedy available to it under this Deed of Trust or the Note or any other document securing or evidencing the Indebtedness.

6.1 Appointment of Receiver. Upon the occurrence of an Event of Default, Lender shall have the right and shall be entitled to have a receiver appointed to take possession of all or any part of the Trust Property, to which Trustor hereby irrevocably consents, (any required hearing or notice of such appointment or proceeding being hereby expressly waived, including, without limitation any rights provided in A.R.S. §33-702(B) and §12-1242). Lender shall be entitled to such appointment either before or after sale, without notice, without a hearing without regard to the solvency or insolvency of the Trustor at the time of application for such receiver, without the requirement of posting of any bond or security and without regard to the then value of the Trust Property or whether the same shall be then occupied as a homestead or not. Lender hereunder or any holder of the Note may be appointed as such receiver, and Trustor hereby irrevocably waives any right it might have to notice of the appointment of a receiver, to a hearing or to the requirement of a bond or other security. Trustor also hereby approves and waives the right to object to any receiver appointed by Lender. Such receiver shall have (i) power to collect the Rents during the pendency of such foreclosure suit and, in case of a sale and a deficiency, during the full statutory period of redemption, whether there be redemption or not, as well as during any further times when Trustor, except for the intervention of such receiver, would be entitled to collect such Rents; and (ii) all other powers which may be necessary or are usual in such cases for the protection, possession, control, management and operation of the Trust

Property during the whole of said period. The court from time to time may authorize the receiver to apply the net income in his hands in payment in whole or in part of: (a) the Indebtedness secured hereby, or by any decree foreclosing this Deed of Trust, or any tax, special assessment or other lien which may be or become superior to the lien hereof or of such decree, provided such application is made prior to foreclosure sale; and (b) after any such foreclosure sale, to the balance due of any amounts secured hereby or by such decree after application of any proceeds obtained by such foreclosure sale.

6.2 Other Remedies. Upon the occurrence of an Event of Default, Lender, at Lender’s option, may exercise any one or more of the following rights and remedies in addition to any other rights or remedies set forth in this Deed of Trust or otherwise provided by law:

6.3.1 UCC Remedies. With respect to all or any part of the personal property located upon or used in connection with the Trust Property (collectively, the “Personal Property”), Lender shall have all the rights and remedies of a secured party under the Uniform Commercial Code.

6.3.2 Enforcement of Assignment of Rents. Lender shall have the right, without notice to Trustor, to exercise any of the remedies provided above in Article 3 and apply the net proceeds, over and above Lender’s costs, against the Indebtedness. In furtherance of this right, Lender may require any tenant or other user of the Trust Property to make payments of all Rents and other amounts payable pursuant to its sublease directly to Lender. If the Rents are collected by Lender, then Trustor irrevocably designates Lender as Trustor’s attorney-in-fact to endorse instruments received in payment thereof in the name of Trustor and to negotiate the same and collection the proceeds. Payments by tenants or other users to Lender in response to Lender’s demand shall satisfy the obligations for which the payments are made, whether or not any proper grounds for the demand existed. Lender may exercise its rights under this subparagraph either in person, by agent, or through a receiver. In addition, Lender may take any of the actions described in Article 3 of this Deed of Trust with or without taking possession of any portion of the Trust Property or taking any action with respect to such possession.

6.3.3 Judicial Action. At Lender’s election, Lender may bring an action in any court of competent jurisdiction to foreclose this instrument as a mortgage or to obtain specific performance of any of the covenants or agreements of this Deed of Trust.

6.3.4 Trustee’s Sale.

(a) Lender may exercise its power of sale as provided by applicable Arizona statues, including but not limited to A.R.S. §§ 33-807 and 33-808. Without limiting the foregoing, Lender may cause to be delivered and recorded any written notice of breach and non-performance and of election to cause all or any part of the Trust Property to be sold that is required by law; and after such time as may then be required, Trustee, without demand on Trustor, shall sell such Trust Property at the time and place fixed by Trustee in such notice of sale, either as a whole or in separate parcels and in such order as Lender may direct (Trustor waiving any right to direct the order of sale), at public auction to the highest bidder for cash in lawful money of the United States (or cash equivalents acceptable to Trustee to the extent permitted by applicable law), payable at the time of sale. Trustee may postpone the sale of all or

any part of the Trust Property by public announcement at the time fixed by the preceding postponement. Trustee shall deliver to the purchaser at such sale its deed conveying the property so sold, but without any covenant or warranty, express or implied, and the recitals in such deed of any matters or facts shall be conclusive proof of the truthfulness thereof. Any person, including Trustee or Lender, may purchase at such sale, and any bid by Lender may be, in whole or in part, in the form of cancellation of all or any part of the secured Indebtedness.

(b) The sale by Trustee of less than the whole of the Trust Property shall not exhaust the power of sale herein granted, and Trustee is specifically empowered to make successive sales under such power until the whole of the Trust Property shall be sold. In the event any sale hereunder is not completed or is defective in the opinion of Lender, such sale shall not exhaust the power of sale hereunder and Lender shall have the right to cause a subsequent sale or sales to be made hereunder. If the proceeds of any sale of less than the whole of the Trust Property shall be less than the aggregate of the secured Indebtedness and the expense of executing this trust as provided herein, this Deed of Trust and the lien hereof shall remain in full force and effect as to the unsold portion of the Trust Property just as though no sale had been made; provided, however, that Trustor shall never have any right to require the sale of less than the whole of the Trust Property but Lender shall have the right, at its, sole election, to request Trustee to sell less than the whole of the Trust Property.

(c) Trustee may, after any request or direction by Lender, sell not only the Real Property but also all other interests which are a part of the Trust Property, or any part thereof, as a unit and as a part of a single sale, or may sell any part of the Trust Property separately from the remainder of the Lessee’s Interest or other Trust Property. It shall not be necessary for Trustee to have taken possession of any part of the Trust Property or to have it present or to exhibit it at any sale.

(d) After each sale, Trustee shall receive the proceeds of said sale and apply the same as provided below in Section 6.3.5. Payment of the purchase price to Trustee shall satisfy the obligation of purchaser at such sale therefor, and such purchaser shall not be responsible for the application thereof.

(e) Trustee or its successor or substitute may appoint or delegate any one or more persons as agent to perform any act or acts necessary or incident to any sale held by Trustee, including the posting of notices and the conduct of sale, but in the name and on behalf of Trustee, its successor or substitute. If Trustee or its successor or substitute shall have given notice of sale hereunder, any successor or substitute Trustee thereafter appointed may complete the sale and the conveyance of the property pursuant thereto as if such notice had been given by the successor or substitute Trustee conducting the sale.

6.3.5 Proceeds of Foreclosure Sale. The proceeds of any sale held by Trustee or Lender or any receiver or public officer in foreclosure of the liens and security interests evidenced hereby shall be applied in accordance with the requirements of applicable laws and to the extent consistent therewith, FIRST, to the payment of all necessary costs and expenses incident to such foreclosure sale, including all attorneys’ fees and legal expenses (including the market value of services provided by in-house counsel), advertising costs, auctioneer’s fees, costs of title rundowns, lien searches, trustee’s sale guaranties, foreclosure sale guaranties,

litigation guaranties and/or other title policies and endorsements, inspection fees, appraisal costs, fees for professional services, environmental assessment and remediation fees, all court costs and charges of every character, and the maximum fee legally permitted, or a reasonable fee when the law provides no maximum limit, to Trustee if foreclosed by power of sale and to the payment of the other secured Indebtedness, including specifically without limitation the principal, accrued interest and attorneys’ fees due and unpaid on the Notes and the amounts due and unpaid and owed to Lender under this Deed of Trust, the order and manner of application to the items in this clause FIRST to be in Lender’s sole discretion; and SECOND, Lender may interplead the remainder in any court of competent jurisdiction, and the amount of any attorneys’ fees, court costs and expenses incurred in such action shall be a part of the Indebtedness and shall be reimbursable (without limitation) from such remainder.

6.3.6 Deficiency Judgment. If permitted by applicable law, Lender may obtain a judgment for any deficiency remaining in the Indebtedness due to Lender.

6.3.7 Tenancy at Sufferance. If Trustor remains in possession of the Trust Property after it is sold as provided above or Lender otherwise becomes entitled to possession of the Trust Property upon default of Trustor, Trustor shall become a tenant at sufferance of Lender or the purchaser of the Trust Property and shall, at Lender’s option, either: (i) pay a reasonable rental for the use of the Trust Property; or (ii) vacate the Trust Property immediately upon the demand of Lender.

6.3.8 Maintenance of Trust Property During Foreclosure. Upon and after the occurrence of an Event of Default, Trustor hereby authorizes and empowers Lender, its successors and assigns: (a) to pay all Taxes, that may have been or that thereafter during the period of redemption from the sale under such foreclosure may be levied or assessed upon any portion of the Trust Property; (b) to keep the Trust Property insured and to pay the premiums therefor as required hereunder during the period of redemption (if any) from the sale under such foreclosure; (c) to keep the Trust Property in thorough repair as required hereunder during the period of redemption, if any, of the sale from such foreclosure; and (d) to enter the Improvements and Real Property and allow its representatives to enter the Improvements and upon the Land and perform an environmental and/or property condition assessment (including inspections and sampling) to assess the condition of the Trust Property and at Lender’s sole option, correct any conditions that Lender, in the exercise of its reasonable discretion deems necessary to comply with Environmental Laws and to keep the Trust Property in thorough repair; to enter upon the Land and Improvements or any part thereof, and to take possession of the Trust Property and all books and records relating thereto, and to exercise without interference from Trustor any and all rights which Trustor has with respect to the management, possession, operation, protection or preservation of the Trust Property. Lender shall not be deemed to have taken possession of the Trust Property or any part thereof except upon the exercise of its right to do so, and then only to the extent evidenced by its demand and overt act specifically for such purpose. All costs, expenses and liabilities of every character incurred by Lender in managing, operating, maintaining, protecting or preserving the Trust Property shall constitute a demand obligation of Trustor (which obligation Trustor hereby promises to pay) to Lender pursuant to this Deed of Trust. In connection with any action taken by Lender pursuant to this Section 6.3.8, Lender shall not be liable for any loss sustained by Trustor resulting from any failure to lease the Trust Property or any part thereof, or from any act or omission of Lender in managing the Trust

Property unless such loss is caused by the willful misconduct and bad faith of Lender, nor shall Lender be obligated to perform or discharge any obligation, duty or liability of Trustor arising under any lease or other agreement relating to the Trust Property or arising under any Permitted Encumbrance or otherwise arising. Trustor assigns to Lender the right from time to time in the name of the owner of the Trust Property to file and prosecute an appeal or other protest of the valuation of the Trust Property or the taxes imposed upon the Trust Property. Trustor hereby assents to, ratifies and confirms any and all actions of Lender with respect to the Trust Property taken under this Section 6.3.8.

6.3.9 Discretion as to Security. In exercising its rights and remedies, Lender shall be free to sell all or any part of the Trust Property together or separately, in one sale or by separate sales, and to execute and deliver to the purchasers of the Trust Property bills of sale and deeds of conveyance pursuant to law. Lender may resort to any security given by this Deed of Trust or to any other security now existing or hereafter given to secure the payment of the secured Indebtedness, in whole or in part, and in such portions and in such order as may seem best to Lender in its sole and uncontrolled discretion, and any such action shall not in anywise be considered as a waiver of any of the rights, benefits, liens or security interests evidenced by this Deed of Trust.

6.3.10 Other Rights. Lender may resort for the payment of the Obligations to any other security held by Lender in such order and manner as Lender, in its discretion, may elect. Lender may take action to recover the Obligations, or any portion thereof, or to enforce any covenant hereof without prejudice to the right of Lender thereafter to foreclose this Deed of Trust. The rights of Lender under this Deed of Trust shall be separate, distinct and cumulative and none shall be given effect to the exclusion of the others. No act of Lender shall be construed as an election to proceed under any one provision herein to the exclusion of any other provision. Lender shall not be limited exclusively to the rights and remedies herein stated but shall be entitled to every right and remedy now or hereafter afforded at law or in equity.

6.3.11 Trustor’s Waivers. To the full extent Trustor may do so, Trustor agrees that Trustor will not at any time insist upon, plead, claim or take the benefit or advantage of any law now or hereafter in force providing for any appraisement, valuation, stay, extension or redemption, homestead, moratorium, reinstatement, marshalling or forbearance, and Trustor, for Trustor, Trustor’s heirs, devisees, representatives, successors and assigns, and for any and all persons ever claiming any interest in the Trust Property, to the extent permitted by applicable law, hereby waives and releases all rights of redemption, valuation, appraisement, stay of execution and all rights to a marshalling of assets of Trustor, including the Trust Property, or to a sale in inverse order of alienation in the event of foreclosure of the liens and/or security interests hereby created. Trustor shall not have or assert any right under any statute or rule of law pertaining to the marshalling of assets, sale in inverse order of alienation, the exemption of homestead, the administration of estates of decedents, or other matters whatsoever to defeat, reduce or affect the right, of Lender under the terms of this Deed of Trust to a sale of the Trust Property for the collection of the secured Indebtedness without any prior or different resort for collection, or the right of Lender under the terms of this Deed of Trust to the payment of the secured Indebtedness out of the proceeds of sale of the Trust Property in preference to every other claimant whatsoever. Without limiting the foregoing, to the maximum extent permitted by law, Trustor unconditionally and irrevocably waives any rights or benefits arising under

A.R.S. §§ 12-1566, 12-1641 through and including 12-1644, 33-814, 33-725, 33-727 and 44-142 and Ariz. R. Civ. P. 17(f) or such statutes, rules or similar provisions as may be enacted or adopted hereafter.

6.4 Reconveyances.

6.4.1 Reconveyance From Deed of Trust. If all of the secured Indebtedness is paid as it becomes due and payable, and all of the covenants, warranties, undertakings and agreements made in this Deed of Trust are kept and performed, and all obligations, if any, of Lender for further advances have been terminated, then, and in that event only, all rights under this Deed of Trust shall terminate (except to the extent expressly provided herein with respect to indemnifications, representations and warranties and other rights which are to continue following the reconveyance hereof) and the Trust Property shall become wholly clear of the liens, security interests, conveyances and assignments evidenced hereby, and the Trust Property shall be reconveyed by Lender in due form at Trustor’s cost. The grantee in such reconveyance may be described as “the person or persons legally entitled thereto.” Without limitation, all provisions herein for indemnity of Lender shall survive discharge of the secured Indebtedness and any foreclosure, reconveyance or termination of this Deed of Trust.

6.4.2 Partial Reconveyance; No Reconveyance in Default. Lender may, regardless of consideration, cause the reconveyance of any part of the Trust Property from the lien of this Deed of Trust without in any manner affecting or impairing the lien or priority of this Deed of Trust as to the remainder of the Trust Property. No partial reconveyance shall be sought, requested or required if any Event of Default has occurred which has not been cured.

6.4.3 Reconveyance Fee. Trustor agrees to pay fees in the maximum amounts legally permitted, or reasonable fees when the law provides no maximum limit, for Trustee’s rendering of services in connection with each partial or complete reconveyance of the Trust Property from the lien of this Deed of Trust.

ARTICLE 7

SECURITY AGREEMENT, FINANCING STATEMENT AND FIXTURE FILING

This Deed of Trust is, pursuant to the Uniform Commercial Code in effect in the State of Arizona, a security agreement and financing statement with respect to that portion of the Trust Property constituting personal property and a fixture filing with respect to all fixtures included within the Trust Property. To the extent required by A.R.S. § 47-9502.B and C, it is hereby recited that because a portion of the Trust Estate may constitute fixtures, this Deed of Trust is to be recorded in the office where a mortgage would be recorded, which is the office of the County Recorder of Apache County, Arizona. Trustor hereby authorizes Lender to execute and file continuation statements without the signature of Trustor if Lender shall determine that such are necessary or advisable in order to perfect Lender’s security interest in such fixtures and personal property and hereby authorizes Lender to execute financing statements to further evidence and secure Lender’s interest in such fixtures and personal property and shall pay to Lender on demand any expenses incurred by Lender in connection with the preparation, execution and

filing of such statements and any continuation statements that may be filed by Lender. Upon the occurrence of any Event of Default, Lender may, at its option, sell or otherwise dispose of such fixtures and personal property by public or private proceedings, separate from or together with the sale of the Trust Property, in accordance with the provisions of the Arizona Uniform Commercial Code, and Lender may with respect to such fixtures and personal property, exercise any other rights or remedies of a secured party under the Arizona Uniform Commercial Code. Lender shall give Trustor reasonable notice of the time and place of any public sale of the Personal Property or of the time after which any private sale or other intended disposition of the Personal Property is to be made. Unless such fixtures and personal property are perishable or threaten to decline speedily in value or are of a type customarily sold on a recognized market, reasonable notice shall mean notice given at least ten (10) days before the time of the sale or other disposition. Upon occurrence of any Event of Default, Lender reserves the option, pursuant to the appropriate provisions of the Arizona Uniform Commercial Code to proceed with respect to such fixtures and personal property as part of the Trust Property in accordance with its rights and remedies with respect to the Trust Property, in which event the default provisions of the Arizona Uniform Commercial Code shall not apply. At Lender’s election, any sale of the Personal Property may be made in conjunction with, or independent of, any sale of other Trust Property.

ARTICLE 8

MISCELLANEOUS

8.1 Limitation on Interest. Trustor agrees that the effective rate of interest under the Note is equal to the rate provided for in the Note together with all other payments of, or in the nature of, interest to be made to Lender under the Loan Documents. If under any circumstances whatsoever, interest hereunder would otherwise be payable at a rate in excess of that permitted under applicable law, then, the interest payable shall be reduced to the maximum amount permitted under applicable law, and if under any circumstance the Lender shall ever receive anything of value deemed interest by applicable law which would exceed interest at the highest lawful rate, an amount equal to any excessive interest shall be applied to the reduction of the principal amount owing under the Loan Documents and any other Obligations and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal under the Loan Documents or any other Obligations, such excess shall be refunded. In the event and only in the event that the applicable law as to the enforcement of this Deed of Trust or any other Loan Documents is held to be the law of the State of Arizona, all loan origination, standby, commitment and other fees, including attorneys’ fees and any commissions or fees paid or to be paid to brokers, prepayment premiums, additional interest, charges, points, goods, things in action or any other sums or things of value, including any compensating balance requirements or other contractual obligations (collectively referred to as the “Additional Sums”) paid or payable by Borrower, whether pursuant to the Loan Documents or otherwise with respect to the indebtedness secured

hereby, or with respect to this Deed of Trust or any other Loan Documents, that under the laws of the State of Arizona may be deemed to be interest with respect to the indebtedness secured hereby shall, for the purpose of any laws of the State of Arizona that may limit the maximum amount of interest to be charged with respect to the indebtedness secured hereby, be payable by Borrower as, and shall be deemed to be, additional interest for such purposes only, and Trustor agrees that the contracted for rate of interest shall be the sum of the interest rate set forth in the Loan Documents or any applicable default rate, as applicable, plus the interest rate resulting from the Additional Sums being considered interest

8.2 Attorneys’ Fees. If Lender institutes any suit or action to enforce any of the terms of this Deed of Trust, Lender shall be entitled to recover such sum as the court may adjudge reasonable as attorneys’ fees at trial and upon any appeal. Whether or not any court action is involved, all reasonable expenses Lender incurs that in Lender’s opinion are necessary at any time for the protection of its interest or the enforcement of its rights shall become a part of the Indebtedness payable on demand and shall bear interest at the applicable interest rate on the Note from the date of the expenditure until repaid. Expenses covered by this paragraph include, without limitation, however subject to any limits under applicable law, Lender’s attorneys’ fees and Lender’s legal expenses whether or not there is a lawsuit, including attorneys’ fees and expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), appeals, and any anticipated post-judgment collection services, the cost of searching records, obtaining title reports (including foreclosure reports), surveyors’ reports, and appraisal fees, title insurance, and fees for the Trustee, to the extent permitted by applicable law. Trustor also will pay any court costs, in addition to all other sums provided by law.

8.3. Powers of Attorney. Every power of attorney given in this Deed of Trust is a power coupled with an interest. In no event shall Lender or the Trustee be obligated to exercise any of the rights and powers for which Trustor has granted Lender and/or the Trustee a power of attorney. For purposes of A.R.S. § 14-5501.E, Trustor acknowledges that each power of attorney given in this Deed of Trust forms a part of this Deed of Trust, that it is security for money and the performance of valuable acts, and that each of Lender and/or the Trustee may exercise the power of attorney for its own benefit and need not exercise it for Trustor’s best interest. Every power of attorney shall be irrevocable and unaffected by the disability of the Trustor so long as any part of the Obligations remain unpaid or unperformed. Trustor hereby separately initials this provision pursuant to A.R.S. §14-5506.B. Such power of attorney and proxy is coupled with an interest, shall survive the dissolution, termination, reorganization or other incapacity of Trustor and shall be irrevocable

8.4 No Waiver. Lender shall not be deemed to have waived any rights under this Deed of Trust unless such waiver is given in writing and signed by Lender. No delay or omission on the part of Lender in exercising any right shall operate as a waiver of such right or any other right. A waiver by Lender of a provision of this Deed of Trust shall not prejudice or constitute a waiver of Lender’s right otherwise to demand strict compliance with that provision or any other provision of this Deed of Trust. No prior waiver by Lender, nor any course of dealing between Lender and Trustor, shall constitute a waiver of any of Lender’s rights or of any of Trustor’s obligations as to any future transactions. Whenever the consent of Lender is required under this Deed of Trust, the granting of such consent by Lender in any instance shall not constitute continuing consent to subsequent instances where such consent is required and in all cases such consent may be granted or withheld in the sole discretion of Lender. The failure of Lender to exercise its option for acceleration of maturity and/or foreclosure following an Event of Default or to exercise any other option granted to Lender hereunder in any one or more instances, or the acceptance by Lender of partial payments hereunder shall not constitute a

waiver of any such default, nor extend or affect the grace period, if any, but such option shall remain continuously in force. Acceleration of maturity once claimed hereunder by Lender may, at the option of Lender, be rescinded by written acknowledgment to that effect by Lender, but the tender and acceptance of partial payments alone shall not in any way affect or rescind such acceleration of maturity, nor extend or affect the grace period, if any.

8.5 Cumulative Rights and Remedies. Election by Lender to pursue any remedy shall not exclude pursuit of any other remedy, and an election to make expenditures or to take action to perform an obligation of Trustor under this Deed of Trust, after Trustor’s failure to perform, shall not affect Lender’s right to declare a default and exercise its remedies. Nothing under this Deed of Trust or otherwise shall be construed so as to limit or restrict the rights and remedies available to Lender following an Event of Default or in any way to limit or restrict the rights and ability of Lender to proceed directly against Trustor and/or against any other co-maker, guarantor, surety or endorser and/or to proceed against any other collateral directly or indirectly securing the Indebtedness.

8.6 Survival of Representations and Warranties. All representations, warranties, and agreements made by Trustor in this Deed of Trust shall survive the execution and delivery of this Deed of Trust, shall be continuing in nature, and shall remain in full force and effect until such time as the Indebtedness shall be paid in full.

8.7 No Effect on Liability. In the event Lender: (a) releases any part of the security described herein or any person liable for any of the Indebtedness; (b) grants one or more renewals, modifications or extensions of the Note for any period or periods of time; (c) takes other or additional security for the payment thereof; or (d) waives or fails to exercise any right granted herein or in the Note, said act or omission shall not release the Trustor, subsequent purchasers of the Trust Property or any part thereof, or makers, guarantors or sureties of this Deed of Trust or of the Note, under any covenant of this Deed of Trust or of the Note or Loan Documents, nor preclude Lender from exercising any rights, powers or privileges herein granted or intended to be granted in the event of any default then made or any subsequent default.

8.8 No Merger. There shall be no merger of the interest or estate created by this Deed of Trust with any other interest or estate in the Trust Property at any time held by or for the benefit of Lender in any capacity, without the written consent of Lender.

8.9 Notices. All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given (i) when delivered by hand (with written confirmation of receipt); (ii) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested); (iii) on the date sent by facsimile or e-mail of a PDF document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next business day if sent after normal business hours of the recipient; or (iv) on the third day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid.

EXHIBIT G

FORM OF UNCONDITIONAL GUARANTY

This UNCONDITIONAL GUARANTY dated as of , 2012 (the “Guaranty”), is executed by American West Potash, LLC, a Delaware limited liability company (“Guarantor”), to and for the benefit of The Karlsson Group, Inc., an Arizona corporation (together with any of its affiliate or subsidiary corporations, or their successors or assigns, being collectively referred to herein as the “Holder”).

RECITALS

WHEREAS, Guarantor is a wholly-owned subsidiary of Prospect Global Resources, Inc., a Delaware corporation (“Maker”);

WHEREAS, Maker and Holder entered into that certain Membership Interest Purchase Agreement dated as of May 30, 2012 (the “Purchase Agreement”), whereby Maker agreed to purchase, and Holder agreed to sell, all of Holder’s limited liability company membership interests in Guarantor;

WHEREAS, part of the purchase price payable by Maker pursuant to the Purchase Agreement is evidenced by that certain Promissory Note, dated as of , 2012, made by Maker in favor of Holder, in the original principal amount of One Hundred Twenty-Five Million Dollars ($125,000,000) (the “Note”); and

WHEREAS, in consideration of Holder entering into the Note, Holder requires that Guarantor guarantee the due performance by Maker of all of Maker’s obligations to Holder under the Note.

NOW, THEREFORE, in consideration of the foregoing promises and for other good and valuable consideration, Guarantor hereby agrees as follows.

AGREEMENT

NOW, THEREFORE, FOR VALUE RECEIVED, it is agreed that the preceding provisions and preambles are an integral part hereof and that this Guaranty shall be construed in light thereof, and in consideration of the terms of the Purchase Agreement, Guarantor hereby unconditionally and absolutely guarantees to the Holder, irrespective of the validity, regularity or enforceability of the Note, the payment in full to the Holder, promptly on demand of the Holder, of the Guaranteed Debt. The term “Guaranteed Debt” shall mean (i) the Obligations, as such capitalized term is defined in the Note, and (ii) all costs associated with the enforcement and perfection of Holder’s security interests pursuant to that certain (x) Security Agreement, dated as

of the date hereof, by and among Holder, Guarantor and Prospect Global Resources, Inc., a Delaware corporation (“Prospect”), and (y) Pledge Agreement, dated as of the date hereof, by and between Holder and Prospect.

1. Expenses. Guarantor agrees to pay all reasonable costs, including outside attorneys’ and paralegals’ fees and expenses of every kind, paid or incurred by the Holder in endeavoring to collect the Guaranteed Debt or any part thereof, or in enforcing its rights in connection with any collateral securing the Guaranteed Debt, or in enforcing this Guaranty, or in defending against any defense, counterclaim, setoff or cross-claim based on any act of commission or omission by the Holder with respect to the Guaranteed Debt, any collateral securing the Guaranteed Debt, or in connection with any Repayment Claim (defined below).

2. Bankruptcy. In case of any bankruptcy, reorganization, debt arrangement or other proceeding under any insolvency law relating to the Maker, any dissolution, liquidation or receivership proceeding is instituted by or against the Maker, or any default by Guarantor of any of the covenants, terms and conditions set forth herein, all of the Guaranteed Debt shall, without notice to anyone, immediately become due or accrued and all amounts due hereunder shall be payable by Guarantor. Guarantor hereby expressly and irrevocably: (a) waives, to the fullest extent possible, on behalf of itself and its successors and assigns (including any surety) and any other person, any and all rights at law or in equity to subrogation, reimbursement, exoneration, contribution, indemnification, set off or to any other rights that could accrue to a surety against a principal, a guarantor against a maker or obligor, an accommodation party against the party accommodated, a holder or transferee against a maker, or to the holder of a claim against any person, and which Guarantor may have or hereafter acquire against any person in connection with or as a result of Guarantor’s execution, delivery and/or performance of this Guaranty, or any other documents to which Guarantor is a party or otherwise; (b) waives any “claim” (as such term is defined in the United States Bankruptcy Code) of any kind against the Maker, and further agrees that it shall not have or assert any such rights against any person (including any surety), either directly or as an attempted set off to any action commenced against Guarantor by the Holder or any other person; and (c) acknowledges and agrees (i) that foregoing waivers are intended to benefit the Holder and shall not limit or otherwise effect Guarantor’s liability hereunder or the enforceability of this Guaranty, and (ii) that the Maker and its successors and assigns are intended third party beneficiaries of the foregoing waivers.

3. Payment Order. All payments received by the Holder on account of the Guaranteed Debt, from whatever source derived, shall be taken and applied by the Holder toward the payment of the Guaranteed Debt and in such order of application as the Holder may, in its sole discretion, from time to time elect. The Holder shall have the exclusive right to determine how, when and what application of payments and credits, if any, whether derived from the Maker or any other source, shall be made on the Guaranteed Debt and such determination shall be conclusive upon Guarantor.

4. Guaranty Unconditional. This Guaranty shall in all respects be absolute and unconditional, and shall remain in full force and effect with respect to Guarantor until: (i) written notice from the Holder to Guarantor as provided for herein; or (ii) until all Guaranteed Debt created or existing before receipt of either such notice shall have been fully paid in cash. In the event of the dissolution of Guarantor, this Guaranty shall continue as to all of the Guaranteed Debt theretofore incurred by the Maker even though the Guaranteed Debt is renewed or the time of maturity of the Maker’s obligations is extended without the consent of the successors or assigns of Guarantor. No failure, neglect or omission to enforce or exercise any right against any other guarantor shall release or discharge Guarantor hereunder.

4. No Discharge. Guarantor’s liability under this Guaranty shall in no way be modified, affected, impaired, reduced, released or discharged by any of the following (any or all of which may be done or omitted by the Holder in its sole discretion, without notice to anyone): (a) any acceptance by the Holder of any new or renewal note or notes of the Maker, or of any security or collateral for, or other guarantors or obligors upon, any of the Guaranteed Debt; (b) any change in the time, place or manner of payment of, amount, or in any other term of, the Guaranteed Debt or any other obligation of Maker under the Note, or any rescission, waiver, amendment or other modification of the Note; (c) any taking, exchange, substitution, release, impairment or non-perfection of any collateral securing the Guaranteed Debt, or any taking, release, impairment, amendment, waiver or other modification of any guaranty, for the Guaranteed Debt; and (d) any change in the Maker’s name or the merger of the Maker into another corporation. Guarantor hereby consents to all acts of commission or omission of the Holder set forth above and agrees that the standards by which good faith, diligence, reasonableness and care shall be measured, determined and governed solely by the terms and provisions hereof.

5. Waivers. In order to hold Guarantor liable hereunder, there shall be no obligation on the part of the Holder, at any time, to resort to payment from the Maker or to anyone else, or to any collateral, security, property, liens or other rights and remedies whatsoever, all of which are hereby expressly waived by Guarantor.

Guarantor hereby expressly waives diligence in collection or protection, presentment, demand or protest or in giving notice to anyone of the protest, dishonor, default, or nonpayment or of the creation or existence of any of the Guaranteed Debt or of any security or collateral therefor or of the acceptance of this Guaranty or indulgences hereunder.

Guarantor waives any and all defenses, claims and discharges of the Maker, or any other obligor, pertaining to the Guaranteed Debt, in each case, only to the extent permitted under applicable law. Without limiting the generality of the foregoing, but only to the extent permitted under applicable law, Guarantor will not assert, plead or enforce against the Holder any defense of waiver, release, discharge in bankruptcy, statute of limitations, res judicata, statute of frauds, anti-deficiency statute, fraud, incapacity, minority, usury, illegality or unenforceability which may be available to the Maker or any other person liable in respect of any of the Guaranteed

Debt, or any setoff available against the Holder to the Maker or any such other person, whether or not on account of a related transaction. Guarantor expressly agrees that, subject to applicable law, it shall be and remain liable for any deficiency remaining after foreclosure of any security interest securing the Guaranteed Debt, whether or not the liability of the Maker or any other obligor for such deficiency is discharged pursuant to statute or judicial decision. For the avoidance of doubt, Guarantor waives any relief available under valuation and appraisement laws and any and all rights or defenses based on suretyship or impairment of collateral including, but not limited to, any rights or defenses arising by reason of: (i) any “one action” or “anti-deficiency” law or any other law which may prevent Holder from bringing any action, including a claim for deficiency, against Guarantor, before or after Holder’s commencement or completion of any foreclosure action, either judicially or if permitted by applicable law by exercise of a power of sale including, but not limited to, any right to a fair market value hearing, any right to offset the amount owed by any amount other than the amount paid at the trustee’s sale, any right to a statute of limitations shorter than six (6) years, and the provisions of A.R.S. §§ 12-1566, 33-814, 33-725, and 33-727; (ii) any election of remedies by Holder which destroys or otherwise adversely affects Guarantor’s subrogation rights or rights to proceed against Holder for reimbursement, including without limitation, any loss of rights Guarantor may suffer by reason of any law limiting, qualifying, or discharging any indebtedness; (iii) any disability or other defense of Maker, of any other guarantor, or of any other person, or by reason of the cessation of Maker’s liability from any cause whatsoever, other than payment in full in legal tender, of the Guaranteed Debt; (iv) any right to claim discharge of the Guaranteed Debt on the basis of unjustified impairment of any collateral for the Guaranteed Debt; (v) any statute of limitations, if at any time any action or suit brought by Holder against Guarantor is commenced, there is outstanding Guaranteed Debt which is not barred by any applicable statute of limitations; or (vi) any defenses given to guarantors at law or in equity other than actual payment and performance of the Guaranteed Debt. If payment is made by Maker, whether voluntarily or otherwise, or by any third party, on the Guaranteed Debt and thereafter Holder is forced to remit the amount of that payment to Maker’s trustee in bankruptcy or to any similar person under any federal or state bankruptcy law or law for the relief of debtors, the Guaranteed Debt shall be considered unpaid for the purpose of the enforcement of this Guaranty or any other obligor for such deficiency is discharged pursuant to statute or judicial decision.

TO THE FULLEST EXTENT PERMITTED BY LAW, GUARANTOR UNCONDITIONALLY AND IRREVOCABLY WAIVES ALL RIGHTS AND BENEFITS UNDER A.R.S. § 44-142, § 12-1641, ET SEQ. AND RULE 17(F) OF THE ARIZONA RULES OF CIVIL PROCEDURE AND ANY SIMILAR STATUTES OR RULES OF PROCEDURE. GUARANTOR WAIVES EVERY DEFENSE, CAUSE OF ACTION, COUNTERCLAIM OR SETOFF, WHICH GUARANTOR MAY NOW HAVE OR HEREAFTER MAY HAVE TO ANY ACTION BY THE HOLDER IN ENFORCING THIS GUARANTY. AS FURTHER SECURITY, ANY AND ALL DEBTS AND LIABILITIES NOW OR HEREAFTER ARISING AND OWING TO GUARANTOR BY THE MAKER, OR TO ANY OTHER PARTY LIABLE TO THE HOLDER FOR THE GUARANTEED DEBT, ARE HEREBY SUBORDINATED TO THE HOLDER’S CLAIMS AND ARE HEREBY ASSIGNED TO THE HOLDER.

GUARANTOR HEREBY AGREES THAT GUARANTOR MAY BE JOINED AS A PARTY DEFENDANT IN ANY LEGAL PROCEEDING (INCLUDING, BUT NOT LIMITED TO, A FORECLOSURE PROCEEDING) INSTITUTED BY THE HOLDER AGAINST THE MAKER. EACH MAKER, GUARANTOR AND THE HOLDER, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, EACH KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE IRREVOCABLY THE RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY SUCH LEGAL PROCEEDING IN WHICH GUARANTOR AND THE HOLDER ARE ADVERSE PARTIES. THIS PROVISION IS A MATERIAL INDUCEMENT TO THE HOLDER GRANTING ANY FINANCIAL ACCOMMODATION TO THE MAKER AND ACCEPTING THIS GUARANTY.

6. Repayment Claim; Setoff; Assignment. Should a claim (a “Repayment Claim”) be made upon the Holder at any time for repayment of any amount received by the Holder in payment of the Guaranteed Debt, or any part thereof, whether received from either Maker or the Guarantor pursuant hereto, or received by the Holder as the proceeds of collateral, by reason of: (i) any judgment, decree or order of any court or administrative body having jurisdiction over the Holder or any of its property; or (ii) any settlement or compromise of any such Repayment Claim effected by the Holder, in its sole discretion, with the claimant (including the Maker), the Guarantors shall remain liable to the Holder for the amount so repaid to the same extent as if such amount had never originally been received by the Holder, notwithstanding any termination hereof or the cancellation of any note or other instrument evidencing any of the Guaranteed Debt. If an Event of Default (as defined in the Note) shall have occurred and be continuing, the Holder may, without demand or notice of any kind to anyone, apply or set off any balances, credits, deposits, accounts, moneys or other indebtedness at any time credited by or due from the Holder to the Guarantor against the amounts due hereunder and in such order of application as the Holder may from time to time elect. Any notification of intended disposition of any property required by law shall be deemed reasonably and properly given if given in the manner provided by the applicable statute.

7. Assignments and Discharge. Unless and until all of the Guaranteed Debt has been paid in full, and to the extent permissible under applicable law, no release or discharge of any other person, whether primarily or secondarily liable for and obligated with respect to the Guaranteed Debt, or the institution of bankruptcy, receivership, insolvency, reorganization, dissolution or liquidation proceedings by or against Maker or any other person primarily or secondarily liable for and obligated with respect to the Guaranteed Debt, or the entry of any restraining or other order in any such proceedings, shall release or discharge Guarantor, or any other guarantor of the Guaranteed Debt, or any other person, firm or corporation liable to the Holder for the Guaranteed Debt.

All references herein to the Maker and Guarantor, respectively, shall be deemed to include any successors or assigns, whether immediate or remote, to Maker or Guarantor, as the case may be.

8. Miscellaneous.

This Guaranty shall be governed by, and construed in accordance with, the internal laws of the State of Arizona, without giving effect to any choice or conflict of law provision or rule (whether of the State of Arizona or any other jurisdiction) that would cause the application of laws of any jurisdiction other than those of the State of Arizona.

Guarantor consents to the sole and exclusive jurisdiction and venue in the Federal or State courts in the County of Maricopa, Arizona, and agree that all disputes based on or arising out of this Guaranty shall only be submitted to and determined by said courts, which shall have sole and exclusive jurisdiction.

Wherever possible each provision of this Guaranty shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Guaranty shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Guaranty.

It is agreed that Guarantor’s liability is independent of any other guaranties at any time in effect with respect to all or any part of the Guaranteed Debt, and that Guarantor’s liability hereunder may be enforced regardless of the existence of any such other guaranties.

No delay on the part of the Holder in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Holder of any right or remedy shall preclude other or further exercise thereof, or the exercise of any other right or remedy. No modification, termination, discharge or waiver of any of the provisions hereof shall be binding upon the Holder, except as expressly set forth in a writing duly signed and delivered on behalf of the Holder.

9. Notice. All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested); (c) on the date sent by facsimile or e-mail of a PDF document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next business day if sent after normal business hours of the recipient or (d) on the third day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid.

SECTION 2. Grant of Security Interest. As security for the prompt and complete payment in full when due (whether at stated maturity, acceleration or otherwise) of all the Secured Obligations, Pledgor hereby pledges, assigns, delivers, and transfers to Secured Party, and hereby grants to Secured Party, a first priority perfected security interest in all of Pledgor’s right, title and interest in and to the following property of Pledgor (all of which being hereinafter collectively called the “Collateral”):

Pledgor shall file a UCC-1 describing the Pledged Equity Interest immediately upon request therefore by Secured Party.

SECTION 4. Distributions on Pledged Equity Interest.

(b) The security interest in the Collateral granted to Secured Party hereunder constitutes a valid and enforceable security interest in the Collateral to the extent that a security interest can be created under Article 9 of the UCC, except as the enforcement thereof may be limited by applicable bankruptcy, insolvency or similar laws affecting the enforcement of rights of creditors generally and except to the extent that enforcement of rights and remedies set forth therein may be limited by equitable principles (regardless of whether enforcement is considered in a court of law or a proceeding in equity).

SECTION 6. Covenants. Pledgor covenants and agrees with Secured Party that from and after the date of this Agreement and until the Secured Obligations have been completely and finally paid in full:

6.1 Further Assurances. At any time and from time to time, upon the reasonable written request of Secured Party, Pledgor will promptly and duly execute and deliver any and all such further instruments, endorsements, powers of attorney and other documents, make such filings, give such notices and take such further action as Secured Party may reasonably deem necessary to obtain the full benefits of this Agreement and of the rights, remedies and powers granted herein.

6.2 Powers, Control, etc.

(a) To the extent the Pledged Equity Interest ever becomes a certificated security, Pledgor agrees to deliver to Secured Party all certificates evidencing the Pledged Equity Interest, which will be accompanied by duly executed undated blank powers, or other equivalent instruments of transfer.

(b) Pledgor shall (i) confirm for Secured Party that Pledgor has marked the company register for the Pledged Equity Interest or other applicable records to reflect the security interest of Secured Party, (ii) notify Secured Party that Pledgor if it has received notice of any Lien upon the Pledged Equity Interest, (iii) not agree to accept instructions from any Person in respect of the Pledged Equity Interest and will not accept or execute any instructions to transfer ownership of the Pledged Equity Interest except from Secured Party, and (iv) upon the occurrence and continuation of an Event of Default, Pledgor will comply with instructions with respect to the Pledged Equity Interest originated by Secured Party.

6.3 Continuous Pledge. Pledgor will, at all times, keep pledged to Secured Party pursuant hereto all Collateral, all distributions with respect thereto, and other securities, instruments, proceeds, and rights from time to time received by or distributable to Pledgor in respect of the Pledged Equity Interest.

6.4 Voting Rights; Distributions, etc. Pledgor agrees that if an Event of Default shall have occurred and be continuing, then:

(a) Pledgor shall, promptly upon receipt thereof by Pledgor, deliver (properly indorsed where required hereby or requested by Secured Party) to Secured Party all distributions, other cash payments, and proceeds of the Pledged Equity Interest, for application against the Secured Obligations; and

(b) at the times as Secured Party has notified Pledgor in writing of Secured Party’s intention to exercise its voting power under this clause:

(i) Secured Party may exercise (to the exclusion of Pledgor) the voting power and all other incidental rights of ownership with respect to the Pledged Equity

Interest and Pledgor hereby grants Secured Party an irrevocable proxy, exercisable under the circumstances, to vote the Pledged Equity Interest; and

(ii) Pledgor shall promptly deliver to Secured Party the additional proxies and other documents as may be necessary to allow Secured Party to exercise the voting power.

Secured Party agrees that until the time as an Event of Default has occurred and is continuing and Secured Party shall have given the notice referred to in Section 6.4(b) above, Pledgor shall have the exclusive voting power with respect to the Pledged Equity Interest; provided, however, that no vote shall be cast, or consent, waiver, or ratification given, or action taken or any action not taken by Pledgor that would be inconsistent with or violate any provision of this Agreement.

SECTION 7. Power of Attorney. Pledgor hereby irrevocably constitutes and appoints Secured Party, with full power of substitution, as its true and lawful attorney in fact with full irrevocable power and authority in the place and stead of Pledgor and in the name of Pledgor or in its own name, from time to time in Secured Party’s reasonable discretion, during the continuance of an Event of Default which has not been waived in writing by Secured Party, for the purpose of carrying out the terms of this Agreement, to take any and all reasonable appropriate action and to execute any and all documents and instruments which are necessary to accomplish the purposes of this Agreement.

SECTION 8. Rights and Remedies Upon Default.

(a) If an Event of Default shall have occurred and be continuing, then Secured Party shall have all the rights of a secured party under the UCC (including, without limitation, the right to dispose of the Collateral in any manner permitted under the UCC), shall have all rights now or hereafter existing under all other applicable laws or in equity, and, subject to any requirements of applicable law then in effect, shall have all the rights set forth in this Agreement. With respect to the enforced collection of the Secured Obligations or the foreclosure of any security interest in the Collateral then securing the Secured Obligations, Secured Party agrees to give Pledgor notice, if any, as required under the UCC.

(b) The obligations of Pledgor under this Agreement shall be absolute and unconditional and shall remain in full force and effect without regard to, and shall not be released, suspended, discharged, terminated or otherwise affected by, any circumstances or occurrence except as specifically provided in this Agreement. The rights, powers and remedies of Secured Party under this Agreement shall be cumulative and not exclusive of any other right, power or remedy which Secured Party may have against Pledgor.

FORM OF REGISTRATION RIGHTS AGREEMENT

THIS REGISTRATION RIGHTS AGREEMENT (the “Agreement”) is made as of this day of , 2012 by and between Prospect Global Resources Inc., a Nevada corporation (the “Company”), and The Karlsson Group, Inc., an Arizona corporation, and any assignees or transferees thereof (the “Investor”).

1. Certain Definitions. As used in this Agreement, the following terms shall have the following respective meanings:

(a) An “Affiliate” of any Person (as defined herein) means a Person that, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with, the first mentioned Person. A Person shall be deemed to control another Person if such first Person possesses, directly or indirectly, the power to direct, or cause the direction of, the management and policies of the second Person, whether through the ownership of voting securities, by contract or otherwise.

(b) “Board of Directors” means the Board of Directors of the Company.

(c) “Commission” shall mean the United States Securities and Exchange Commission, or any other federal agency at the time administering the Securities Act and the Exchange Act.

(d) “Common Stock” shall mean the common stock of the Company, par value $0.001 per share, and any other class of securities into which such securities may hereafter be reclassified or changed.

(e) “Exchange Act” shall mean the Securities Exchange Act of 1934, as amended, or any similar successor federal statute, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the time.

(f) “Holders” shall mean the holders of Registrable Securities.

(g) “Majority Interest” means Holders holding not less than a majority in interest of the Registrable Securities held by all Holders.

(h) “Person” shall mean an individual, a corporation, an association, a joint venture, a partnership, a limited liability company, an estate, a trust, an unincorporated organization, and any other entity or organization, governmental or otherwise.

(i) “Registrable Securities” shall mean 5,605,834 shares of Common Stock initially issuable upon exercise of the Warrant and any additional securities issued pursuant to the terms of the Warrant.

(j) “Registration Expenses” shall mean the expenses so described in Section.

(k) “Securities Act” shall mean the Securities Act of 1933, as amended, or any similar successor federal statute, and the rules and regulations of the Commission thereunder, all as the same shall be in effect at the time.

(l) “Warrant” shall mean the Warrant dated the date hereof issued to Investor to purchase 5,605,834 shares of Common Stock.

2. Demand Registration. At any time beginning as of the date hereof, Holders of a majority of the Registrable Securities may require registration (a “Demand Registration”) under the Securities Act of all or any part of their Registrable Securities; provided that each such Demand Registration must be in respect of at least 100,000 shares of Common Stock. Holders may exercise this demand registration right under this Section 2 by giving a written request to the Company specifying the intended method of disposition of Holders’ Registrable Securities. Within five (5) business days of receipt of such request, the Company shall promptly notify all other Holders of the request. The Holders shall have thirty (30) days after receipt by such Holder of such notice from the Company to request that their Registrable Securities be included in the registration with the shares of the Holders initially requiring registration pursuant to this Section 2. Holder will be entitled to require up to two (2) Demand Registrations on Form S-1 and unlimited Demand Registration on Form S-3 (or any respective successor forms). A Demand Registration under this Section 2 shall not be deemed to have been effected or requested (a) unless a Registration Statement with respect thereto has become effective and Holder is legally permitted to sell the Registrable Securities included therein and the Registration Statement remains effective for at least one hundred eighty (180) consecutive days (unless the Registrable Securities are sold within a shorter period, then the Registration Statement shall have remained effective for such shorter period); (b) if after the Registration Statement has become effective, a stop-order, injunction or order suspending the effectiveness of the Registration Statement is issued or any other limitation, restriction or suspension of the offer or sale of any Registrable Securities has been imposed and the Registrable Securities covered thereby have not been sold; or (c) if the conditions to be fulfilled by the Company for completion of the transactions contemplated by the selling agreement or underwriting agreement related to the registration are not satisfied by the Company or waived by the underwriters.

(a) If Holders of a majority of the Registrable Securities being registered so elect, a Demand Registration may be in the form of an underwritten offering. If the Demand Registration is an underwritten offering, Holders of a majority of the Registrable Securities being registered will have the right to select the investment bankers and managers for the offering, subject to the Company’s approval, which approval shall not be unreasonably withheld. In a Demand Registration that is an underwritten offering, as many securities of the Company that the Company elects may be included in such registration on the same terms and conditions as the Registrable Securities to be included in such registration; however, if the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and other securities to be included in the registration exceeds the number that can be sold in such offering at a price satisfactory to Holders, the Company will give priority for inclusion in such registration: (a) first, to the Registrable

Securities requested to be included in such registration by Holders and (b) second, to the securities the Company elects to be included in such registration.

(b) The Company may delay a Demand Registration for up to ninety (90) days if a majority of the Company’s Board of Directors determines that it would be significantly detrimental to the Company to proceed with the registration. Notwithstanding anything in this Section 2 to the contrary, the Company will not be obligated to effect a Demand Registration within six months after the effective date of a previous Demand Registration.

3. Piggyback Registration. If the Company at any time proposes to register any of its Common Stock under the Securities Act for sale to the public either for its own account or for the account of another Person other than Holder, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, each such time it will promptly give written notice to the Holders of its intention to effect such registration. Upon the written request of any such Holder given within 30 days after receipt by such Holder of such notice, the Company will, subject to the limits contained in this Section 3, use its reasonable best efforts to cause all Registrable Securities of such Holder that such Holder so requests to be registered under the Securities Act and qualified for sale under any state blue sky law, all to the extent required to permit such sale or other disposition of said Registrable Securities; provided, however, that if the Company is advised in writing in good faith by the managing underwriter of the Company’s securities being offered in an underwritten public offering pursuant to such registration statement that the amount to be sold by persons other than the Company (collectively, “Selling Stockholders”) is greater than the amount which can be offered without adversely affecting the marketability of the offering, the Company may reduce the amount offered for the accounts of Selling Stockholders (including any Holders) to a number reasonably deemed satisfactory by such managing underwriter; and provided, further, that the securities to be excluded shall be determined in the following sequence: (i) first, securities held by any Persons not having any contractual incidental or “piggy back” registration rights, and (ii) second, Registrable Securities and securities held by any Persons having contractual incidental or “piggy back” registration rights pursuant to an agreement which is not this Agreement. If there is a reduction in the number of shares of Common Stock or Registrable Securities to be registered pursuant to clauses (i) and (ii) above, such reduction shall be made within each tranche on a pro rata basis (based upon the aggregate number of shares of Registrable Securities held by the holders in each such tranche).

6. Indemnification.

(a) The Company shall indemnify and hold harmless each selling Holder of Registrable Securities, each underwriter (as defined in the Securities Act), and each other Person who

participates in the offering of such securities and each other Person, if ally, who controls (within the meaning of the Securities Act) such seller, underwriter or participating Person (individually and collectively, the “Indemnified Person”) against any losses, claims, damages or liabilities (collectively, the “liability”), joint or several, to which such Indemnified Person may become subject under the Securities Act or any other statute or at common law, insofar as such liability (or action in respect thereof) arises out of or is based upon (i) any untrue statement or alleged untrue statement of any material fact contained, on the effective date thereof, in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation by the Company of the Securities Act, any state securities or “blue sky” laws or any rule or regulation thereunder in connection with such registration. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a) as it pertains to any preliminary prospectus, shall not inure to the benefit of any Indemnified Person if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented, if such corrected prospectus was timely made available by the Company pursuant to Section 4(f), and the Indemnified Person was promptly advised in writing not to use the incorrect prospectus prior to the use giving rise to a violation and such Indemnified Person, notwithstanding such advice, used such incorrect prospectus. Except as otherwise provided in Section 6(d), the Company shall reimburse each such Indemnified Person in connection with investigating or defending any such liability as expenses in connection with the same are incurred; provided, however, that the Company shall not be liable to any Indemnified Person in any such case to the extent that any such liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, preliminary or final prospectus, or amendment or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by such Indemnified Person specifically for use therein.

(b) Each selling Holder of any securities included in such registration being effected shall indemnify and hold harmless each other selling holder of any securities, the Company, its directors and officers, each underwriter and each other Person, if any, who controls the Company or such underwriter (individually and collectively also the “Indemnified Person”), against any liability, joint or several, to which any such Indemnified Person may become subject under the Securities Act or any other statute or at common law, insofar as such liability (or actions in respect thereof) arises out of or is based upon (i) any untrue statement or alleged untrue statement of any material fact contained, on the effective date thereof, in any registration statement under which securities were registered under the Securities Act at the request of such selling holder, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or (ii) any omission or alleged omission by such selling holder to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in the case of (i) and (ii) to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in such registration statement, preliminary or final prospectus, amendment or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by such selling holder specifically for use therein. Such selling Holder’s obligations hereunder shall be limited to an amount equal to the proceeds to such selling Holder of the securities sold in any such registration,

(c) Indemnification similar to that specified in Section 6(a) and Section 6(b) shall be given by the Company and each selling Holder (with such modifications as may be appropriate) with respect to any required registration or other qualification of their securities under any federal or state law or regulation of governmental authority other than the Securities Act.

(d) If the indemnification provided for in this Section 6 for any reason is held by a court of competent jurisdiction to be unavailable to an Indemnified Person in respect of any losses, claims, damages, expenses or liabilities referred to therein, then each Indemnifying Party under this Section 6, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, expenses or liabilities (1) in such proportion as is appropriate to reflect the relative benefits received by the Company, the selling Holders and the underwriters from the offering of the Registrable Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above, but also the relative fault of the Company, the other selling Holders and the underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, expenses or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, the selling Holders and the underwriters shall be deemed to be in the same respective proportions that the net proceeds from the offering (before deducting expenses) received by the Company and the selling Holders and the underwriting discount received by the underwriters, in each case as set forth in the table on the cover page of the applicable prospectus, bear to the aggregate public offering price of the Registrable Securities. The relative fault of the Company, the selling Holders and the underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the selling Holders or the underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the selling Holders and the underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata or per capita allocation or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraph. In no event, however, shall a selling Holder be required to contribute any amount under this Section 6(d) in excess of the lesser of (i) that proportion of the total of such losses, claims, damages or liabilities indemnified against equal to the proportion of the total Registrable Securities sold under such registration statement which are being sold by such selling Holder or (ii) the net proceeds received by such selling holder from its sale of Registrable Securities under such registration statement. No person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation.

7. Compliance with Rule 144. The Company will use its reasonable best efforts to file with the Commission such information as is required under the Exchange Act for so long as there are holders of Registrable Securities; and in such event, the Company shall use its reasonable best efforts to take all action as may be required as a condition to the availability of Rule 144 under the Securities Act (or any comparable successor rules). The Company shall furnish to any holder of Registrable Securities upon request a written statement executed by the Company as to the steps it

has taken to comply with the current public information requirement of Rule 144 (or such comparable successor rules). Subject to the limitations on transfers imposed by this Agreement, or any other agreement to which the Holders and the Company are a party, the Company shall use its reasonable best efforts to facilitate and expedite transfers of Registrable Securities pursuant to Rule 144 under the Securities Act, which efforts shall include timely notice to its transfer agent to expedite such transfers of Registrable Securities.

8. Amendments. The provisions of this Agreement may be amended, and the Company may take any action herein prohibited or omit to perform any act herein required to be performed by it, only with the written consent of the Company and a Majority Interest.

9. Transferability of Registration Rights. The registration rights set forth in this Agreement are transferable by the Investor to each transferee of Registrable Securities. Each subsequent holder of Registrable Securities must consent in writing to be bound by the terms and conditions of this Agreement in order to acquire the rights granted pursuant to this Agreement.

10. Rights Which May Be Granted to Subsequent Parties. Other than transferees of Registrable Securities under Section 9 hereof, the Company shall not, without the prior written consent of a Majority Interest, allow purchasers of the Company’s securities to become a party to this Agreement.

11. Damages. The Company recognizes and agrees that each Holder of Registrable Securities will not have an adequate remedy if the Company fails to comply with the terms and provisions of this Agreement and that damages will not be readily ascertainable, and the Company expressly agrees that, in the event of such failure, it shall not oppose an application by any holder of Registrable Securities or any other Person entitled to the benefits of this Agreement requiring specific performance of any and all provisions hereof or enjoining the Company from continuing to commit any such breach of this Agreement. The Company agrees to pay all reasonable costs, legal expenses and attorneys’ and paralegals’ fees actually incurred by the Holder in endeavoring to enforce its rights hereunder.

12. Governing Law; Jurisdiction; Venue.

(a) This Agreement shall be governed by and construed in accordance with the internal laws of the State of California without giving effect to any choice or conflict of law provision or rule (whether of the State of California or any other jurisdiction) that would cause the application of laws of any jurisdiction other than those of the State of California.

(b) The parties consent to the sole and exclusive jurisdiction and venue in the Federal or State courts in the County of Los Angeles, California, and agree that all disputes based on or arising out of this Agreement shall only be submitted to and determined by said courts, which shall have sole and exclusive jurisdiction.

13. Miscellaneous.

(a) All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if

sent by a nationally recognized overnight courier (receipt requested); (c) on the date sent by facsimile or e-mail of a PDF document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next business day if sent after normal business hours of the recipient or (d) on the third day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid.

(b) The security interest in the Collateral granted to Secured Party hereunder constitutes a valid and enforceable security interest in the Collateral to the extent that a security interest can be created under Article 9 of the UCC, except as the enforcement thereof may be limited by applicable bankruptcy, insolvency or similar laws affecting the enforcement of rights of creditors generally and except to the extent that enforcement of rights and remedies set forth herein may be limited by equitable principles (regardless of whether enforcement is considered in a court of law or a proceeding in equity).

(c) Secured Party at all times shall have a perfected security interest in the Collateral that shall be prior to any other interest therein except for Permitted Liens. Each Prospect Party will do all acts and things, and will execute and file all instruments (including, without limitation, any and all security agreements, mortgages, deeds of trusts, assignments of rents, assignments of proceeds, attornment documents, financing statements, and continuation statements) required by Secured Party to establish, maintain and continue the perfected security interest of Secured Party in the Collateral, and will promptly on demand, pay all costs and expenses of filing and recording, including the cost of any searches reasonably deemed necessary by Secured Party from time to time to

(d) Each Prospect Party, at its expense, will, to the extent commercially feasible, insure the Collateral, with Secured Party as loss payee, against such hazards and in such form and in such amounts and with such companies as Secured Party may from time to time require, and will deliver the policies or appropriate certificates to Secured Party. Any such insurance policies shall provide for at least thirty (30) days’ written notice to Secured Party of cancellation, reduction in amount or material change in coverage of the insurance. In the event that any Prospect Party fails to obtain or renew any insurance required hereunder within fifteen (15) days prior to its expiration, Secured Party may do so and charge the cost thereof to Debtor, pursuant to Section 3(i)herein. Secured Party is hereby irrevocably appointed the attorney-in-fact of each Prospect Party. As such entity’s attorney-in-fact, Secured Party, without any obligation to do so, may make, adjust or settle any claims under such insurance or pursuant to cancellation of such insurance and endorse any check or draft that may be payable to such Prospect Party, alone or jointly with other payees, so that Secured Party may collect the proceeds for any loss under such insurance. Subject to the right to restore as set forth in the Deed of Trust, the proceeds of such insurance, less any costs and expenses incurred or paid by Secured Party in the collection thereof, shall be applied to repayment of the Secured Obligations, whether or not due and in any order of priority, and any balance shall be refunded to the applicable Prospect Party. Any such application of insurance proceeds shall not cure or waive any default hereunder.

(e) Each Prospect Party at its cost and expense shall protect and defend the security interest of Secured Party and all of the rights of Secured Party hereunder against the claims and demands of all other parties.

(f) To the extent applicable, each Prospect Party shall at all times keep and maintain the Collateral in good working order, repair and condition and permit no waste thereof, and shall from time to time make all necessary and proper repairs, replacements and additions thereto, so that the efficiency thereof shall be fully preserved and maintained, all as satisfactory to Secured Party. All such replacements shall be free of any other lien, security interest or encumbrance of any nature. Each Prospect Party shall maintain in full force and effect all leases, contracts, servitudes and other agreements forming a part of any of the Collateral and shall perform all of its obligations thereunder, including, but not limited to, the timely payment of all rents, royalties and other payments due and payable thereunder or otherwise attendant to such Prospect Party’s ownership or operation of the Collateral. No Prospect Party shall amend, modify or otherwise revise any such lease, contract, servitude or other agreement if such amendment, modification or revision would have a material and adverse effect on the value of Collateral.

EXHIBIT M

FORM OF

WARRANT TO PURCHASE COMMON STOCK

PROSPECT GLOBAL RESOURCES INC.

PROSPECT GLOBAL RESOURCES INC., a Nevada corporation (the “Company”), HEREBY CERTIFIES THAT, for value received, THE KARLSSON GROUP, INC., an Arizona corporation, or registered assigns (each a “Holder”), is entitled to purchase up to [ ] shares of Common Stock at a purchase price of $4.25 per share (the “Exercise Price”). As used herein, the term “Common Stock” means the Company’s Common Stock, par value $0.001 per share, as constituted on the date of original issue of this Warrant. The number and character of such shares of Common Stock is subject to adjustment as provided below. The term “Warrant” as used herein shall include this Warrant, and any warrants delivered in substitution or exchange therefor as provided herein.

1. Term of Warrant. Capitalized terms used in this Section 1 but not defined in this Warrant shall have the meanings ascribed to them in that certain Membership Interest Purchase Agreement by and among The Karlsson Group, Inc., an Arizona corporation, Prospect Global Resources, Inc., a Delaware corporation and American West Potash, LLC, a Delaware corporation dated as of the date hereof (the “Purchase Agreement”). Subject to the terms and conditions set forth herein, this Warrant shall be exercisable, in whole or in part, during the term commencing on the earlier of (i) the Closing Date, and (ii) the Expiration Date, and ending at 5:00 p.m., Mountain Time, on the seven year anniversary of the Effective Date hereof, and shall be void thereafter.

2. Exercise of Warrant.

(a) Method of Exercise. The purchase rights represented by this Warrant are exercisable by the Holder in whole or in part, at any time, or from time to time during the term hereof as described in Section 1 above, by the surrender of this Warrant and the Notice of Exercise annexed hereto duly completed and executed on behalf of the Holder, at the principal

office of the Company (or such other office or agency of the Company as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Company), upon payment in cash or by check acceptable to the Company. Notwithstanding any provisions herein to the contrary, if the fair market value of one share of Common Stock is greater than the Warrant Price for one share of Common Stock (at the date of calculation, as set forth below), in lieu of exercising this Warrant for cash, the holder may elect to receive shares of Common Stock equal to the value (as determined below) of this Warrant (or the portion thereof being canceled), computed using the following formula (the “Cashless Exercise”); provided that the Cashless Exercise shall apply to no more than 1,121,167 Warrants.

	CS =	WCS (FMV-WP)
	FMV

WHERE

CS equals the number of Shares of Common Stock to be issued to the Holder

WCS equals the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being cancelled (at the date of such calculation)

FMV equals the Fair Market Value (as defined below) of one share of Common Stock (at the date of such calculation

WP equals the per share Warrant Price (as adjusted to the date of such calculation) of the Warrant

As used in this Section 2(a), the term “Fair Market Value” of each Warrant Share as of any date shall be (i) if the Common Stock is not then listed on a national securities exchange the volume weighted average price per share of Common Stock (as reported on the exchange, market or quotation system on which shares of Common Stock are admitted to trading or listed) for the five consecutive trading days ending on the business day prior to such exercise, (ii) if the Common Stock is then listed on a national securities exchange, the last sale price in respect of the Common Stock on the Nasdaq Global Market or any national securities exchange on which the Common Stock is then listed at the close of trading on the business day prior to such exercise or (iii) if not so available, Fair Market Value shall be determined as follows: (A) if the parties hereto can agree on the Fair Market Value, such agreed upon value shall constitute the Fair Market Value; (B) if the parties cannot reach an agreement as to the Fair Market Value within five (5) business days from the onset of negotiations, then the Appraised Value (as defined below) shall constitute the Fair Market Value. “Appraised Value” per Warrant Share as of a date specified herein shall mean the value of such a share as of such date as determined by a nationally recognized valuation or appraisal firm (an “Appraiser”) selected jointly by the holder of this Warrant and the Company. If the Company and the holder of this Warrant cannot agree on a mutually acceptable Appraiser, then the Company and the holder of this Warrant shall each choose one such Appraiser and the respective chosen firms shall jointly select a third Appraiser,

which shall make the determination. The Company and the Warrant Holders shall each pay half of the costs and fees of each such Appraiser, and the decision of the Appraiser making such determination of Appraised Value shall be final and binding on the Company and all affected holders of Warrants. No discount shall be applied on account of any lack of liquidity of the Common Stock, the Warrant or the Warrant Shares, including the fact that the Warrants or Warrant Shares may constitute “restricted securities” for securities law purposes.

(b) Issuance of Shares. This Warrant shall be deemed to have been exercised immediately prior to the close of business on the date of its surrender for exercise as provided above, and the person entitled to receive the shares of Common Stock issuable upon such exercise shall be treated for all purposes as the holder of record of such shares as of the close of business on such date. As promptly as practicable on or after such date and in any event within ten (10) days thereafter, the Company at its expense shall issue and deliver to the person or persons entitled to receive the same a certificate or certificates for the number of shares issuable upon such exercise. In the event that this Warrant is exercised in part, the Company at its expense will execute and deliver a new Warrant of like tenor exercisable for the number of shares for which this Warrant may then be exercised.

3. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. In lieu of any fractional share to which the Holder would otherwise be entitled (after aggregating all shares that are being issued upon such exercise), the Company shall make a cash payment equal to the Exercise Price multiplied by such fraction or, at the Company’s option, round the number of shares to be issued up to the next whole number.

4. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and substance to the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount.

5. Rights of Stockholders. Subject to Section 11 and 13 of this Warrant, the Holder shall not be entitled to vote or receive dividends or be deemed the holder of Common Stock or any other securities of the Company that may at any time be issuable on the exercise hereof for any purpose, nor shall anything contained herein be construed to confer upon the Holder, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, or change of stock to no par value, consolidation, merger, conveyance, or otherwise) or to receive notice of meetings, or to receive dividends or subscription rights or otherwise until this Warrant shall have been exercised as provided herein.

6. Transfer of Warrant.

(a) Warrant Register. The Company will maintain a register (the “Warrant Register”) containing the names and addresses of the Holder or Holders. Any Holder of this Warrant or any portion thereof may change its address as shown on the Warrant Register by written notice to the Company requesting such change. Any notice or written communication required or permitted to be given to the Holder may be delivered or given by mail to such Holder as shown on the Warrant Register and at the address shown on the Warrant Register. Until this Warrant is transferred on the Warrant Register of the Company, the Company may treat the Holder as shown on the Warrant Register as the absolute owner of this Warrant for all purposes, notwithstanding any notice to the contrary.

(b) Warrant Agent. The Company may, by written notice to the Holder, appoint an agent for the purpose of maintaining the Warrant Register referred to in Section 6(a) above, issuing the Common Stock or other securities then issuable upon the exercise of this Warrant, exchanging this Warrant, replacing this Warrant, or any or all of the foregoing (the “Warrant Agent”). Thereafter, any such registration, issuance, exchange or replacement, as the case may be, shall be made at the office of the Warrant Agent.

(c) Transferability and Negotiability of Warrant. This Warrant may not be transferred or assigned in whole or in part without compliance with all applicable federal and state securities laws by the transferor and the transferee (including the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, if such are requested by the Company). Subject to the provisions of this Warrant with respect to compliance with the Securities Act of 1933, as amended (the “Act”), title to this Warrant may be transferred by endorsement (by the Holder executing the Assignment Form annexed hereto) and delivery in the same manner as a negotiable instrument transferable by endorsement and delivery.

(d) Exchange of Warrant Upon a Transfer. On surrender of this Warrant for exchange, properly endorsed on the Assignment Form and subject to the provisions of this Warrant with respect to compliance with the Act and with the limitations on assignments and transfers contained in this Section 6, the Company at its expense shall issue to or on the order of the Holder a new warrant or warrants of like tenor, in the name of the Holder or as the Holder (on payment by the Holder of any applicable transfer taxes) may direct, for the number of shares issuable upon exercise hereof.

7. Capital Structure of PGRX. As of May 30, 2012, (i) 39,489,173 shares of common stock, par value $0.001 per share, of PGRX (“Common Stock”) were issued and outstanding, (ii) 3,965,000 options to purchase shares of Common Stock were issued and outstanding, (iii) 4,085,000 shares of Common Stock were reserved for issuance pursuant to options, and (iv) 12,097,363 warrants to purchase shares of common stock were issued and outstanding. As of May 30, 2012, the total number of shares outstanding on a fully diluted basis is 59,636,536.

8. SEC Reports. PGRX has filed all forms, reports, statements, certifications and other documents (including all exhibits, amendments and supplements thereto) required to be filed by it with the SEC pursuant to the Exchange Act or other applicable United States federal securities Laws (“SEC Reports”). As of their respective filing dates, the SEC Reports complied as to form

in all material respects with the applicable requirements of the Securities Act and Exchange Act. None of the SEC Reports when filed with the SEC and, if amended, as of the date of such amendment contained any untrue statement of a material fact or omitted to state a material fact required to be stated or incorporated by reference therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

9. Compliance with Securities Laws.

(i) The Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant and the shares of Common Stock to be issued upon exercise hereof are being acquired for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any shares of Common Stock to be issued upon exercise hereof except under circumstances that will not result in a violation of the Act or any state securities laws.

(ii) This Warrant and all shares of Common Stock issued upon exercise hereof or conversion thereof shall be stamped or imprinted with a legend in substantially the following form (in addition to any legend required by state securities laws):

10. Reservation of Stock. The Company covenants that during the term this Warrant is exercisable, the Company will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the exercise of this Warrant and, from time to time, will take all steps necessary to amend its Certificate of Incorporation (the “Certificate”) to provide sufficient reserves of shares of Common Stock issuable upon exercise of this Warrant. The Company further covenants that all shares of Common Stock that may be issued upon the exercise of rights represented by this Warrant and payment of the Exercise Price, all as set forth herein will be duly and validly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously therewith). The Company agrees that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for shares of Common Stock upon the exercise of this Warrant.

11. Notices.

(a) Whenever the Exercise Price or the shares purchasable hereunder shall be adjusted pursuant to Section 13 hereof, the Company shall issue a certificate signed by its Chief Financial Officer setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Exercise Price and the shares purchasable hereunder after giving effect to such adjustment, and shall cause a copy of such certificate to be delivered to the Holder of this Warrant by overnight courier service.

(b) In case:

(i) the Company shall take a record of the holders of its Common Stock (or other stock or securities at the time receivable upon the exercise of this Warrant) for the purpose of entitling them to receive any dividend or other distribution, or any right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right, or

(ii) of any capital reorganization of the Company, any reclassification of the capital stock of the Company, any consolidation or merger of the Company with or into another corporation or entity, or any conveyance of all or substantially all of the assets of the Company to another corporation or entity, or

(iii) of any voluntary or involuntary dissolution, liquidation or winding-up of the Company, then, and in each such case, the Company will deliver to the Holder by overnight courier a notice specifying, as the case may be, (A) the date on which a record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (B) the date on which such reorganization, reclassification, consolidation, merger, conveyance, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or such stock or securities at the time receivable upon the exercise of this Warrant) shall be entitled to exchange their shares of Common Stock (or such other stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, conveyance, dissolution, liquidation or winding-up. Such notice shall be delivered at least ten days prior to the record date specified in (A) above or twenty (20) days prior to the date specified in (B) above, in each case by overnight courier.

12. Amendments and Waivers.

(a) Except as provided in Section 12(b) below, this Warrant, or any provision hereof, may be amended, waived, discharged or terminated only by a statement in writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought.

(b) Any term or condition of this Warrant may be amended or waived with the written consent of the Company and holders of Warrants representing more than two-thirds of the shares of Common Stock issuable upon the exercise of all then outstanding Warrants (the “Majority Holders”), even without the consent of the Holder. Any amendment effected in accordance with this Section 12(b) shall be binding upon each holder of any of the Warrants, each future holder of any of the Warrants, and the Company; provided, however, that no special consideration or inducement may be given to any such holder in connection with such consent that is not given ratably to all such holders, and that such amendment must apply to all such holders equally and ratably. The Company shall promptly give notice to all holders of Warrants of any amendment effected in accordance with this Section 12(b).

(c) No waivers of, or exceptions to, any term, condition or provision of this Warrant, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.

13. Adjustments. The Exercise Price and the shares purchasable hereunder are subject to adjustment from time to time as follows:

(a) Merger, Reorganization, Sale of Company, etc. If at any time while this Warrant is outstanding and unexpired there shall be (i) a reorganization (other than a combination, reclassification, exchange or subdivision of shares otherwise provided for herein), (ii) a merger or consolidation of the Company with or into another corporation in which the Company is not the surviving entity, or a reverse merger in which the Company is the surviving entity but the shares of the Company’s capital stock outstanding immediately prior to the merger are converted or exchanged by virtue of the merger into other property, whether in the form of securities, cash or otherwise, or (iii) a sale or transfer of the Company’s properties and assets as, or substantially as, an entirety to any other corporation or other entity, then, as a part of such reorganization, merger, consolidation, sale or transfer, lawful provision shall be made so that the holder of this Warrant shall thereafter be entitled to receive upon exercise of this Warrant, during the period specified herein and upon payment of the Exercise Price then in effect, the number of shares of stock or other securities or property of the successor corporation or other entity resulting from such reorganization, merger, consolidation, merger, sale or transfer that a holder of the shares deliverable upon exercise of this Warrant would have been entitled to receive in such reorganization, consolidation, merger, sale or transfer if this Warrant had been exercised immediately before such reorganization, merger, consolidation, sale or transfer, all subject to further adjustment as provided in this Section 13. The foregoing provision of this Section 13(a) shall similarly apply to successive reorganizations, consolidations, mergers, sales and transfers and to the stock or securities of any other corporation or other entity that are at the time receivable upon the exercise of this Warrant. If the per-share consideration payable to the Holder for shares in connection with any such transaction is in a form other than cash or marketable securities, then the value of such consideration shall be determined by the Company’s Board of Directors in good faith. In all events, appropriate adjustment (as determined in good faith by the Company’s Board of Directors) shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder after the transaction, to the end that the provisions of this Warrant shall be applicable after that event, as near as reasonably may be, in relation to any shares or other property deliverable after that event upon exercise of this Warrant.

(b) Reclassification, etc. If the Company, at any time while this Warrant remains outstanding and unexpired, by reclassification of securities or otherwise, shall change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities of any other class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights under this Warrant immediately prior to such reclassification or other change and the Exercise Price therefor shall be appropriately adjusted, all subject to further adjustment as provided in this Section 13.

(e) Other Adjustments. In case any event shall occur as to which the other provisions of this Section 13 are not strictly applicable but as to which failure to make any adjustment would not fairly protect the exercise rights represented by this Section 13 in accordance with the essential intent and principles hereof then, in each such case, the Majority Holders may appoint a firm of independent public accountants of recognized national standing reasonably acceptable to the Company, which shall give their opinion as to the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the exercise rights represented herein. Upon receipt of such opinion, the Company will promptly mail a copy thereof to all holders of Common Warrants and shall make the adjustments described therein.
