At the end of the 5-year period, the Parties may renegotiate and extend all or any portion of the Agreement in a mutually agreeable written agreement. Provided, however, such termination at the end of five years shall have no effect on the purchase and sale of the Properties, as described in Articles 3 and 4, below. 2.2 PRIOR AGREEMENTS. This Agreement replaces the Management Agreement and all MAB/PetroHunter Agreements in their entirety, provided however, the Parties shall perform any obligations which accrued under such agreements prior to the Effective Date, including 2 247148 without limitation PetroHunter's obligation to pay any and all amounts which accrued to MAB's benefit under the Management Agreement which remain unpaid. 3. PURCHASE AND SALE 3.1 ASSIGNMENT OF OIL AND GAS PROPERTIES. On or before the Closing Date, MAB shall: (a) assign and transfer to PetroHunter (or its designated subsidiary or affiliate) in one or more assignments and, PetroHunter shall accept and assume, all of MAB's working interest and other interests and obligations in and related to the Properties, and (b) sell and assign to PetroHunter (or its designated subsidiary or affiliate) all of MAB's shares of Sweetpea Petroleum Pty Ltd. (the "Sweetpea Shares"). (collectively, the "MAB Working Interest") with an effective date of said assignments being January 1, 2007, in accordance with the terms herein and substantially in the form of assignments attached as Exhibits A, B, and C (collectively, the "MAB/PetroHunter Assignment"). PetroHunter shall fully assume all of MAB's obligations to the third parties under the Underlying Agreements. Revenues and expenses attributable to the Properties shall be allocated as of the Effective Date, as further set forth in Article 4, below. 3.2 MAB RESERVATION OF OVERRIDING ROYALTY INTEREST. MAB hereby relinquishes in its entirety the overriding royalty reserved by MAB under the Management Agreement and under each of the MAB/PetroHunter Agreements. PetroHunter shall assign to MAB the following overriding royalty. All of the Properties, including Future Properties, shall be subject to MAB's overriding royalty interest in the amount of five percent (5%) (proportionately reduced, based on PetroHunter's net revenue interest in each lease, license or permit as of the Effective Date) of the proceeds of all sales of Hydrocarbons on the Properties or on lands pooled or unitized therewith (the "Reserved ORRI"). The Reserved ORRI shall be calculated based on the wellhead value of the product, and therefore shall be subject to paying or netting back to the wellhead (from the downstream sales price, if product is not sold at the wellhead) MAB's proportionate share of post-production costs, including gathering, transportation, processing costs and/or fees. The Reserved ORRI shall be conveyed to MAB in a form similar to the Assignment of Overriding Royalty, attached as Exhibit D, and shall continue in effect as long as oil and gas is produced from the Properties. Provided, however, the Reserved ORRI: (a) will not apply to or burden any lease within the area known as the Piceance II properties (as defined in the applicable Underlying Agreement) in any respect; and (b) will be proportionately reduced or will not apply to the extent it causes PetroHunter Operating Company's (or other affiliate or subsidiary of PetroHunter) net revenue interest to be less than 75% (proportionately reduced) under any lease. Further, in the event a lease is subject to an overriding royalty owned by a third party, as of the Effective Date, and such overriding royalty subsequently converts to a working interest after payout, thereby resulting in an increase in PetroHunter's net revenue interest, MAB's Reserved ORRI shall nevertheless remain at said proportionately reduced level that was determined as of the Effective Date. 3.3 PETROHUNTER SHARES. In addition to being subject to the Reserved ORRI, PetroHunter shall issue and deliver to MAB the following shares and shall execute the Promissory Note described in Section 3.5, as further consideration for MAB's assignment and relinquishment of the MAB Working Interest: Within thirty days after Closing, PetroHunter shall issue to MAB fifty million (50,000,000) shares of its common stock, valued as of the close of 3 247148 trading on December 29, 2006, which is $1.62 (US) per share. PetroHunter shall also deliver up to fifty million (50,000,000) additional shares (the "Additional Shares") in accordance with, and subject to, Schedule 1, attached hereto, and pursuant to the determination and calculation of the Proved Reserves, as set forth in Schedule 2, attached hereto. The Additional Shares shall be valued as of the close of trading on the date on which each Proved Reserves Threshold set forth in Schedule 1 is met. If PetroHunter does not achieve one trillion cubic feet of Proved Reserves within five years from the Effective Date, MAB will retain the number of Additional Shares which PetroHunter is obligated to issue up to that time, and the balance of Additional Shares, if any, will not be issued, and any right to earn or receive such remaining Additional Shares shall be forfeited by MAB. MAB's voting rights to each portion or number of the Additional Shares shall commence at the point in time when PetroHunter has achieved the applicable Proved Reserves Threshold, in accordance with Schedules 1 and 2, and not before such point in time. 3.4 SUBSIDIARY SHARES. As further consideration for MAB's assignment of the MAB Working Interest, PetroHunter shall: (a) cause PetroHunter Energy NT ("PH/NT") to issue to MAB 25 million shares of PH/NT; and (b) cause any subsidiary which it forms in the future to issue to MAB 7% of the total combined number of shares which such subsidiary issues to PetroHunter and MAB at the time of the formation of such subsidiary; provided, however, said 7% shall be proportionately reduced to the extent that the value of the assets of said subsidiary (as mutually determined by MAB and PetroHunter) is based on properties which are not owned by PetroHunter or its subsidiaries as of January 1, 2007. For example, if PetroHunter forms a subsidiary during the year 2008, and transfers properties into said subsidiary which were owned by PetroHunter (or a subsidiary) as of January 1, 2007, and also transfers properties into the new subsidiary which were acquired by PetroHunter (or a subsidiary) after January 1, 2007, and the relative value of the new properties and the pre-Effective Date properties is 50/50, MAB will receive shares in said new subsidiary comprising 3.5% of the total number of shares issued by the new sub (at the time of its formation) to PetroHunter and MAB combined. 3.5 PROMISSORY NOTE. At Closing, as further consideration for MAB's assignment of the MAB Working Interest, PetroHunter shall execute the Promissory Note substantially in the form of Exhibit F, in the principal amount of $13.5 million, payable in arrears in monthly installments of $225,000, commencing on the first day after Closing (retroactive to the Effective Date), accruing interest at LIBOR (to be adjusted quarterly), and which shall be unsecured and subordinated to any other indebtedness in existence as of the date of this Agreement or which is incurred by PetroHunter or any affiliate or subsidiary in the future. 3.6 CONSIDERATION BY MAB. In addition to the conveyance of the MAB Working Interests, as further consideration for the Reserved ORRI, the Monthly Payment, the issuance of PetroHunter shares, and the assumption of MAB's obligations under the Underlying Agreements by PetroHunter, MAB hereby relinquishes its right to the Carried Interest and Capital Costs Advances, as defined in the Management Agreement and the MAB/PetroHunter Agreements, any overriding royalty interest other than the Reserved ORRI, and any right to serve as operator of the Properties (collectively the "Relinquishment"), and MAB shall provide the Consulting Services described in Section 5, below. 3.7 INDEPENDENT EVALUATION. MAB hereby acknowledges that Gustavson Associates LLC has been retained by PetroHunter to conduct an independent analysis and evaluation of the reasonable value of the MAB Working Interest, the Reserved ORRI, the Consulting Services, and all other consideration to be exchanged by the Parties under this Agreement. MAB further acknowledges that this Agreement and PetroHunter's obligation to 4 247148 close this transaction is contingent upon such evaluation concluding, and PetroHunter's board of directors agreeing, that the consideration transferred and assigned from MAB to PetroHunter under this Agreement represents a fair and reasonable market value as compared to the consideration transferred and assigned from PetroHunter to MAB. 4. ACCOUNTING 4.1 OWNERSHIP OF PRODUCTION. MAB shall be entitled to receive its proportionate share of proceeds, less expenses, from all production and products attributable to the Properties prior to the Effective Date (the "Net Proceeds"). All Net Proceeds after the Effective Date shall be for the account of PetroHunter. 4.2 ACCOUNTING. No later than sixty (60) days following the Closing, PetroHunter shall prepare and deliver to MAB a detailed accounting of the Net Proceeds (the "Accounting"). MAB shall have ten (10) days to review the Accounting. If MAB has no objections or does not object within said ten day period, the Accounting shall be deemed final. If MAB objects to the Accounting, the Parties shall use good faith efforts to resolve their differences with ten (10) days. PetroHunter shall remit the Net Proceeds to MAB no later than thirty (30) days following the Parties mutual written approval of the Accounting. 4.3 PRORATION OF TAXES. MAB shall be responsible for its proportionate share of all taxes, including, but not limited to, excise taxes, state severance taxes, ad valorem taxes, and any other local, state and/or federal taxes or assessments attributable to the Properties ("Taxes") prior to the Effective Date, and all deductions, credits, and refunds pertaining to MAB's proportionate interest of the Taxes ("Deductions") prior to the Effective Date, no matter when received, shall belong to MAB. All Taxes attributable to the Properties after the Effective Date, shall be PetroHunter's responsibility, and all Deductions pertaining to the Properties after the Effective Date, no matter when received, shall belong to PetroHunter. The Parties' respective responsibility for ad valorem Taxes shall be based on the tax year for purposes of assessment. 4.4 LETTERS-IN-LIEU. At Closing, the Parties shall execute all documents necessary to effect change of ownership, such as letters-in-lieu of division orders or transfer orders to each purchaser of production for the Properties, instructing each to make payments for all purchases accruing after the end of the month in which Closing occurs directly to PetroHunter. 4.5 PREPAIDS. Prepaid insurance premiums, utility charges, rentals and any other prepaids or accrued payables applicable to periods following the Effective Date, if any, attributable to the Properties shall be prorated as of the Effective Date, and amounts owing from such proration shall be settled in the Accounting. 4.6 AUDITS. In order to verify information provided by the Parties under this Article 4, the Parties shall each have the right to conduct an audit of the other Party's data relating thereto for a period of two (2) years after the Closing Date. 5. CONSULTING SERVICES 5.1 SERVICES . MAB shall provide the following services to PetroHunter during the Term: (a) strategic business advice on an ongoing basis, including but not limited to financing and financing strategies; (b) locate, identify and make recommendations for the acquisition of additional 5 247148 properties by PetroHunter (the "Future Properties"); (c) review, analyze, and assist in negotiating the acquisition of oil and gas properties identified by PetroHunter; and (d) MAB's exclusive obligation to PetroHunter to identify future acquisition opportunities, subject to Section 5.3, below.

LAVOLD ------------------------------- -------------------------------------- Marc A. Bruner, President Garry D. Lavold, President 11 247148 SCHEDULE 1 (Acquisition and Consulting Agreement Between PetroHunter Energy Corporation and MAB Resources LLC, dated effective January 1, 2007) ISSUANCE OF ADDITIONAL SHARES TO MAB PROVED RESERVES NUMBER OF SHARES TO BE THRESHOLDS (BILLIONS OF ISSUED TO MAB UPON CUBIC FEET) REACHING THRESHOLD BCF -------------- ----------------- 150 5,000,000 300 6,000,000 500 9,000,000 1,000 30,000,000 ----------------- TOTAL 50,000,000 247148 SCHEDULE 2 (Acquisition and Consulting Agreement Between PetroHunter Energy Corporation and MAB Resources LLC, dated effective January 1, 2007) DETERMINATION OF PROVED RESERVES THRESHOLDS 1. PetroHunter shall calculate Proved Reserves no less frequently than on a semi-annual basis each fiscal year. In the event PetroHunter files an 8-K with the Securities Exchange Commission describing an event which could reasonably be expected to result in a material increase in Proved Reserves, PetroHunter shall undertake a calculation of Proved Reserves irrespective of whether PetroHunter has already satisfied its obligation to calculate Proved Reserves no less frequently than on a semi-annual basis each fiscal year. 2. In the event a Proved Reserves Threshold on Schedule 1 has been met, PetroHunter shall give prompt notice to MAB, and shall promptly issue to MAB the number of Additional Shares corresponding to that Proved Reserves Threshold. 3. To the extent a preceding Proved Reserves Threshold on Schedule 1 has not been previously met, but a subsequent Proved Reserves Threshold has been met, PetroHunter shall give prompt written notice to MAB, and shall promptly issue to MAB the total number of Additional Shares corresponding to all Proved Reserves Thresholds that have been met. EXAMPLE. PetroHunter's first two calculations of Proved Reserves indicate less than 150 Bcf of Proved Reserves, but the third calculation of Proved Reserves indicates 1,000 Bcf of Proved Reserves. Under this example, PetroHunter would issue to MAB all 50,000,000 Additional Shares. 4. For purposes of this Agreement, PetroHunter may utilize reasonable internal calculations of Proved Reserves, as such term is defined herein, and MAB shall accept such calculations as valid and final. 5. PetroHunter calculations of Proved Reserves constitute highly confidential and proprietary information, except in the case where such calculations are based upon information previously disclosed to the public. MAB agrees to enter into a confidentiality agreement and such other arrangements as will be required to comply with financial reporting disclosure and securities laws. 247148
