Except for the Leases set forth

(b) All producing oil and gas ▇▇▇▇▇ operated by Poplar and included in the Poplar Properties are being operated and produced and, to the Knowledge of Magellan, have been drilled in accordance in all material respects with reasonable, prudent oil and gas field practice and in compliance in all material respects with applicable Leases and Applicable Law. All oil and gas ▇▇▇▇▇ actually producing and related material equipment are in an operable state of repair, adequate to maintain normal operations in accordance with past practices, ordinary wear and tear excepted. All producing and non-producing oil and gas ▇▇▇▇▇ operated by Poplar and included in the Poplar Properties, excluding temporarily abandoned and plugged and abandoned oil and gas ▇▇▇▇▇ (the “▇▇▇▇▇”), are set forth in Section 2.10 of the Magellan Disclosure Schedule.

(c) All material proceeds from the sale of Hydrocarbons produced from the Poplar Properties are being received by Poplar in a timely manner and are not being held in suspense for any reason (except in the ordinary course of business).

(d) Except as would not, individually or in the aggregate, have a Material Adverse Effect on Poplar, neither Poplar (as to ▇▇▇▇▇ operated by Poplar) nor, to Magellan’s Knowledge, an applicable operator (as to ▇▇▇▇▇ not operated by Poplar), is in material breach of, or default under, any Lease, oil, gas, and mineral lease and sublease, royalty, overriding royalty, net profits interest, mineral fee interest, carried interest, interests under a concession, production sharing, risk service, technical service, service, or similar agreement that relates to, or constitutes an interest in, the Poplar Properties.

There are no actions, examinations or audits currently pending or, to Magellan’s Knowledge, threatened with respect to any of the Companies in respect of any Tax.

One Stone is duly qualified and in good standing to do business as a foreign limited partnership in each jurisdiction in which the conduct or nature of its business or the ownership, leasing, holding or operating of its properties makes such qualification necessary,

except such jurisdictions where the failure to be so qualified or in good standing, individually or in the aggregate, would not have a Material Adverse Effect on One Stone.

Section 3.2 Authority Relative to this Agreement. One Stone has the full limited partnership power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. The execution, delivery and performance by One Stone of this Agreement, and the consummation of the transactions contemplated hereby, have been duly authorized, and no other limited partnership proceedings on the part of One Stone are necessary to authorize the execution, delivery and performance by One Stone of this Agreement and the consummation of the transactions contemplated hereby. This Agreement has been duly executed and delivered by One Stone and, assuming the due authorization, execution and delivery of the other Parties, constitutes, and each other agreement, instrument or document executed or to be executed by One Stone in connection with the transactions contemplated hereby has been, or when executed will be, duly executed and delivered by One Stone and, assuming the due authorization, execution and delivery of the other Parties, constitutes, or when executed and delivered will constitute, a valid and legally binding obligation of One Stone enforceable against One Stone in accordance with its respective terms, except that such enforceability may be limited by Creditor Rights.

Section 3.3 Noncontravention. The execution, delivery and performance by One Stone of this Agreement and the consummation it of the transactions contemplated hereby, do not and will not (i) conflict with or result in a violation of any provision of the limited partnership agreement or other governing instruments of One Stone, (ii) conflict with or result in a violation of any provision of, or constitute (with or without the giving of notice or the passage of time or both) a default under, or give rise (with or without the giving of notice or the passage of time or both) to any right of termination, cancellation or acceleration under, any bond, debenture, note, mortgage, indenture, lease, contract, agreement or other instrument or obligation to which One Stone is a party or by which One Stone may be bound, (iii) result in the creation or imposition of any Encumbrance upon any property of One Stone, including the Preferred Stock, or (iv) assuming compliance with the matters referred to in Section 3.4, violate any Applicable Law binding upon One Stone.

Section 3.4 Governmental Approvals. To the Knowledge of One Stone, no material consent, approval, order or authorization of, or declaration, filing or registration with, any Governmental Authority is required to be obtained or made by One Stone in connection with the execution, delivery or performance by it of this Agreement or the consummation by it of the transactions contemplated hereby, other than (i) compliance with any applicable state securities or takeover laws, and (ii) filings with Governmental Authorities to occur in the ordinary course following the consummation of the transactions contemplated hereby.

One Stone is acquiring the Poplar Membership Interests and Utah CO2 Common Units included in the Exchange Consideration for its own account for investment purposes only and not with a view to the distribution thereof. One Stone is an accredited investor as that term is defined in Regulation D promulgated by the SEC under the Securities Act. One Stone understands and agrees that the Poplar Membership Interests and Utah CO2 Common Units have not been registered under the Securities Act or any state securities laws, and that accordingly, they will not be fully transferable except as permitted under various exemptions contained in the Securities Act and applicable state securities laws, or upon satisfaction of the registration and prospectus delivery requirements of the Securities Act and applicable state securities laws. One Stone acknowledges that it must bear the economic risk of its investment in the Poplar Membership Interests and Utah CO2 Common Units for an indefinite period of time because they have not been registered under the Securities Act and applicable state securities laws and therefore cannot be sold unless they are subsequently registered or an exemption from registration is available. Absent an effective registration statement under the Securities Act and applicable state securities laws covering the disposition of the Poplar Membership Interests and Utah CO2 Common Units, One Stone will not sell, transfer, assign, pledge, hypothecate or otherwise dispose of any or all of the Poplar Membership Interests and Utah CO2 Common Units, respectively, absent a valid exemption from the registration and prospectus delivery requirements of the Securities Act and the registration or qualification requirements of any applicable state securities laws.

Except for the representations and warranties contained in this Agreement, One Stone disclaims all liability and responsibility for any representation, warranty, projection, forecast, statement or information made, communicated or furnished (orally or in writing) to Magellan or any of its Affiliates or any of its officers, directors, managers, employees or agents (including any opinion, information, projection or advice that may have been or may be provided to Magellan by any director, officer, employee, agent, consultant or representative of One Stone or any of its Affiliates).

Section 3.9 Independent Evaluation. In entering into this Agreement, One Stone acknowledges and affirms that it has relied and will rely solely on the terms of this Agreement and upon its independent analysis, evaluation and investigation of, and judgment with respect to, the business, economic, legal, Tax

or other consequences of this transaction, including its own estimate and appraisal of the extent and value of the Hydrocarbons associated with the Poplar Properties.

(a) Except as otherwise permitted by this Section 4.3, Magellan shall not, and shall use its best efforts to cause its directors, officers, employees, investment bankers, financial advisors, attorneys, accountants, agents and other representatives (collectively, “Representatives”) not to, directly or indirectly (i) solicit, initiate, knowingly facilitate, knowingly encourage or knowingly induce any inquiries or any proposals that could reasonably be expected to lead to or constitute the submission of an Alternative Proposal, (ii) participate or engage in any discussions or negotiations with, or disclose or furnish any non-public information, relating to an Alternative Proposal, (iii) approve, recommend, execute or enter into any confidentiality agreement, merger agreement, letter of intent, agreement in principle, stock purchase agreement, asset purchase agreement or exchange agreement, option agreement or other similar agreement relating to an Alternative Proposal (an “Acquisition Agreement”), or (iv) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in a manner adverse to One Stone, the Magellan Board Recommendation or publicly recommend the approval or adoption of, or publicly approve or adopt, or propose to publicly recommend, approve or adopt, any Alternative Proposal (the taking of any action described in clause (iii) being referred to as an “Adverse Recommendation Change”). Without limiting the foregoing, Magellan acknowledges and agrees that any material breach of the foregoing restrictions by Magellan’s Representatives shall be deemed to be a breach of this Section 4.3 by Magellan.

(b) Notwithstanding anything to the contrary contained in Section 4.3(a), if at any time prior to obtaining the Magellan Stockholder Approval, (i) Magellan has received an Alternative Proposal that the Magellan Board believes is bona fide, (ii) the Magellan Board, after consultation with its financial advisors and outside legal counsel, determines in good faith that such Alternative Proposal constitutes or could reasonably be expected to lead to or result in a Superior Proposal and (iii) such Alternative Proposal did not result from a material breach of this Section 4.3, then Magellan may (A) furnish information, including confidential information, with respect to Poplar, Utah CO2 or, if formed pursuant to Section 4.9(f), Newco,

to the Person making such Alternative Proposal, and (B) participate in discussions or negotiations regarding such Alternative Proposal; provided that (x) Magellan shall not, and shall use reasonable best efforts to cause its Representatives not to, disclose any non-public information to such Person unless Magellan has, or first enters into, a customary confidentiality agreement with such Person with confidentiality provisions that are not less restrictive to such Person than the provisions of the Confidentiality Agreement are to One Stone and (y) Magellan shall provide to One Stone any non-public information with respect to Poplar, Utah CO2 and, if formed pursuant to Section 4.9(f), Newco, that was not previously provided or made available to One Stone prior to or substantially concurrently with providing or making available such non-public information to such other Person.

(c) In addition to the other obligations of Magellan set forth in this Section 4.3, Magellan shall promptly advise One Stone, orally and in writing, and in no event later than three (3) Business Days after receipt, if any proposal, offer, inquiry or other contact is received by, any information is requested from, or any discussions or negotiations are sought to be initiated with, Magellan in respect of any Alternative Proposal, and shall, in any such notice to One Stone, indicate the identity of the Person making such proposal, offer, inquiry or other contact and the terms and conditions of any proposals or offers or the nature of any inquiries or contacts (and shall include with such notice copies of any written materials received from or on behalf of such Person relating to such proposal, offer, inquiry or request), and thereafter shall promptly keep One Stone reasonably informed of all material developments affecting the status and terms of any such proposals, offers, inquiries or requests (and Magellan shall promptly provide One Stone with copies of any additional written materials received by Magellan or that Magellan has delivered to any third party making an Alternative Proposal that relate to such proposals, offers, inquiries or requests) and of the status of any such discussions or negotiations.

(d) Notwithstanding the foregoing, if Magellan receives a written Alternative Proposal that the Magellan Board believes is bona fide and the Magellan Board, after consultation with its financial advisors and outside legal counsel, concludes that such Alternative Proposal constitutes a Superior Proposal, then the Magellan Board may, at any time prior to obtaining the Magellan Stockholder Approval, if it determines in good faith, after consultation with outside legal counsel, that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties under Applicable Law, effect an Adverse Recommendation Change and/or enter into an Acquisition Agreement; provided, however, that Magellan shall not be entitled to exercise its right to make any Adverse Recommendation Change in response to a Superior Proposal or execute or enter into an Acquisition Agreement for a Superior Proposal until three (3) Business Days after Magellan provides written notice to One Stone (a “Magellan Notice”) advising One Stone that the Magellan Board or a committee thereof has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal, and identifying the Person or group making such Superior Proposal and, at the request of One Stone, Magellan shall negotiate in good faith with One Stone during such three (3) Business Day period, with respect to any alternative transaction (including any modifications to the terms of this Agreement) that would allow the Magellan Board not to make such Adverse Recommendation Change consistent with its fiduciary duties (it being understood that any change in the financial or other material terms of a Superior Proposal shall require a new Magellan Notice and a new three (3) Business Day period under this Section 4.3(d)).

(e) For purposes of this Agreement:

(i) “Alternative Proposal” means any inquiry, proposal or offer from any Person or “group” (as defined in Section 13(d) of the Exchange Act), other than One Stone, relating to any (A) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of assets of Poplar, Utah CO2 or, if formed pursuant to Section 4.9(f), Newco, equal to twenty percent (20%) or more of the consolidated assets of Poplar, Utah CO2 and, if formed pursuant to Section 4.9(f), Newco, on a combined basis or to which twenty percent (20%) or more of Poplar’s revenues on a consolidated basis are attributable, (B) direct or indirect acquisition (whether in a single transaction or a series of related transactions) of beneficial ownership (within the meaning of Section 13 under the Exchange Act) of twenty percent (20%) or more of any class of equity securities of Poplar, Utah CO2 or, if formed pursuant to Section 4.9(f), Newco, or (C) merger, consolidation, unit exchange, share exchange, business combination, recapitalization, liquidation, dissolution or similar transaction involving Poplar, Utah CO2 or, if formed pursuant to Section 4.9(f), Newco, which is structured to permit such Person or group to acquire beneficial ownership of at least twenty percent (20%) of the consolidated assets or equity interests of Poplar, Utah CO2 or, if formed pursuant to Section 4.9(f), Newco; in each case, other than the transactions contemplated hereby; provided, however, that no inquiry, proposal or offer shall be considered an Alternative Proposal if it relates solely to Magellan, its Securities and/or its assets exclusive of the CO2 Business (the “Retained Magellan Business”), and Magellan shall not be subject to any limitations under this Section 4.3 with respect to solicitations, inquiries, proposals, offers, negotiations, information or agreements relating solely to the Retained Magellan Business, and no public disclosure relating solely to the Retained Magellan Business shall be considered an Adverse Recommendation Change.

(ii) “Superior Proposal” means a bona fide written Alternative Proposal, obtained after the date of this Agreement and not in breach of this Section 4.3, which is on terms and conditions which the Magellan Board determines in good faith, after consultation with its financial advisors and outside legal counsel, taking into account all legal, financial, regulatory, timing and other aspects of the proposal, all conditions contained therein and the person making the proposal, to be more favorable to the Magellan Stockholders from a financial point of view than the transactions contemplated hereby (after giving effect to any adjustments to the terms and provisions of this Agreement committed to in writing by One Stone in response to such Alternative Proposal); provided, that, for purposes of this definition of “Superior Proposal,” the term “Alternative Proposal” shall have the meaning assigned to such term in (i), except that the reference to “20%” in the definition of “Alternative Proposal” shall be deemed to be a reference to “50%.”

(f) Nothing contained in this Agreement shall prevent Magellan or the Magellan Board from issuing a “stop, look and listen” communication pursuant to Rule 14d-9(f) under the Exchange Act or complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act or other Applicable Law with respect to an Alternative Proposal if the Magellan Board determines in good faith (after consultation with outside legal counsel) that the failure to take such action would be reasonably likely to be inconsistent with its fiduciary duties under Applicable Law; provided that any Adverse Recommendation Change may only be

made in accordance with Section 4.3(d). For the avoidance of doubt, a public statement that describes Magellan’s receipt of an Alternative Proposal and the operation of this Agreement with respect thereto shall not be deemed an Adverse Recommendation Change.

Section 4.4 Commercially Reasonable Efforts.

(a) Subject to the terms and conditions of this Agreement (including Section 4.3 and Section 4.4(c)), each of Magellan and One Stone shall cooperate with the other and use (and shall cause its respective Subsidiaries to use) its commercially reasonable efforts to (i) take, or cause to be taken, all actions, and do, or cause to be done, all things, necessary, proper or advisable to cause the conditions to the Closing to be satisfied as promptly as practicable (and in any event no later than the Outside Date) and to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated hereby, including preparing and filing promptly and fully all documentation to effect all necessary filings, notifications, notices, petitions, statements, registrations, submissions of information, applications and other documents (including any required or recommended filings under applicable Antitrust Laws), (ii) obtain promptly (and in any event no later than the Outside Date) all approvals, consents, clearances, expirations or terminations of waiting periods, registrations, permits, authorizations and other confirmations from any Governmental Authority or third party necessary, proper or advisable to consummate the transactions contemplated hereby, including, but not limited to, any consents required in connection with the assignment of the Other Assigned Contract to One Stone, (iii) defend any lawsuits or other Proceedings challenging this Agreement or the consummation of the transactions contemplated hereby and (iv) obtain all necessary consents, approvals or waivers from third parties. For purposes of this Agreement, “Antitrust Laws” means the ▇▇▇▇▇▇▇ Act, as amended, the ▇▇▇▇▇▇▇ Act, as amended, the HSR Act, the Federal Trade Commission Act, as amended, and all other Applicable Laws issued by a Governmental Authority that are designed or intended to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade or lessening of competition.

(b) In furtherance and not in limitation of the foregoing, each of Magellan and One Stone shall use its commercially reasonable efforts to (i) take all action necessary to ensure that no state takeover statute or similar Applicable Law is or becomes applicable to any of the transactions contemplated hereby and (ii) if any state takeover statute or similar Applicable Law becomes applicable to any of the transactions contemplated hereby, take all action necessary to ensure that such transaction may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise minimize the effect of such Applicable Law on the transaction.

(c) Magellan and One Stone (including by causing their respective Subsidiaries) agree to use their reasonable best efforts to (i) resolve any objections that a Governmental Authority or other Person may assert under any Antitrust Law with respect to the transactions contemplated hereby, and (ii) avoid or eliminate each and every impediment under any Antitrust Law that may be asserted by any Governmental Authority with respect to the transactions contemplated hereby, in each case, so as to enable the Closing to occur as promptly as practicable and in any event no later than the Outside Date.

Section 4.5 Public Announcements. The initial press release with respect to the execution of this Agreement shall be prepared by Magellan and shall not be issued without One Stone’s consent, which

will not be unreasonably withheld or delayed. Thereafter, no Party shall issue or cause the publication of any press release or other public announcement (except to the extent made in accordance with this Agreement) with respect to this Agreement or the transactions contemplated hereby without the prior consent of the other Parties (which consent shall not be unreasonably withheld or delayed), except as may be required by Applicable Law or by any applicable NASDAQ Stock Market Rules as determined in the good faith judgment of such Party (provided that such Party uses reasonable best efforts to afford the other Parties an opportunity to first review the content of the proposed disclosure and provide reasonable comment regarding the same); provided, however, that Magellan shall not be required by this Section 4.5 to consult with any other party with respect to a public announcement in connection with (i) the receipt and existence of an Alternative Proposal that the Magellan Board believes is bona fide, (ii) an Adverse Recommendation Change and (iii) matters related thereto, but nothing in this proviso shall limit any obligation of Magellan under Section 4.3(c) to advise and inform One Stone; provided, further, that each Party and its respective Affiliates may make statements that are consistent with statements made in previous press releases, public disclosures or public statements made by Magellan or One Stone in compliance with this Section 4.5.

Section 4.6 Access to Information. Magellan shall afford One Stone reasonable access and assistance to conduct customary due diligence for a period of review beginning with the execution of this Agreement and ending on the later of (a) fifteen (15) Business Days or (b) fifteen (15) days prior to the filing of the preliminary Proxy Statement with the SEC. Without limiting the foregoing, upon reasonable notice and subject to Applicable Laws relating to the exchange of information, Magellan shall, and shall cause each of Poplar, Utah CO2 and, if formed pursuant to Section 4.9(f), Newco, to, afford to One Stone and its Representatives reasonable access during normal business hours (and, with respect to books and records, the right to copy) to all of Magellan’s, Poplar’s, Utah CO2’s and, if formed pursuant to Section 4.9(f), Newco’s, properties, commitments, books, contracts, records and correspondence (in the case of Magellan, relating to the business of Poplar, Utah CO2 or, if formed pursuant to Section 4.9(f), Newco, and in each case, whether in physical or electronic form), officers, employees, accountants, counsel, financial advisors and other Representatives.

Section 4.7 Notification of Certain Matters. One Stone shall give prompt notice to Magellan, and Magellan shall give prompt notice to One Stone, of (a) any notice or other communication received by such Party from any Governmental Authority in connection with the transactions contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated hereby, (b) any actions, suits, claims, investigations or proceedings commenced or, to such Party’s Knowledge, threatened against, relating to or involving or otherwise affecting such Party or any of its Subsidiaries and that relate to the transactions contemplated hereby, (c) the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which, would result in the failure to be satisfied of any of the conditions to the Closing in ARTICLE V and (d) any material failure of such Party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereby which would result in the failure to be satisfied of any of the conditions to the Closing in ARTICLE V; provided that, in the case of clauses (c) and (d), the failure to comply with this Section 4.7 shall not result in the failure to be satisfied of any of the conditions to the Closing in ARTICLE V, or give rise to any right to terminate this Agreement under ARTICLE VI, if the underlying fact, circumstance, event or failure would not in and of itself give rise to such failure or right.

Section 4.8 Fees and Expenses. All fees and expenses incurred in connection with the transactions contemplated hereby including all legal, accounting, financial advisory, consulting and all other fees and expenses of third parties incurred by a Party in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the transactions contemplated hereby, shall be the obligation of the respective Party incurring such fees and expenses, provided, however, that, if the Exchange is consummated pursuant to this Agreement, each of Magellan and One Stone shall be responsible for 50% of the combined total, reasonable, out-of-pocket documented transaction fees and expenses incurred by Magellan (a) relating to the Magellan Fairness Opinion, (b) paid to the outside legal counsel of Magellan in connection with the review, evaluation, negotiation, documentation and performance of this Agreement or any of the transactions contemplated hereby, and (c) relating to the Magellan Stockholder Meeting, the Proxy Statement and other required filings, subject to a maximum obligation by One Stone of $400,000 in the aggregate.

Section 4.9 Tax Matters.

(a) Tax Returns and Payment of Taxes.

(i) Pre-Closing Pass-Through Tax Returns. Magellan will cause to be prepared all Pre-Closing Pass-Through Tax Returns of the Companies. At least five days prior to the due date for filing any such Tax Return, Magellan will deliver a copy of such Tax Return to One Stone. For the avoidance of doubt, Magellan (and the other owners of Utah CO2) shall be solely responsible for, and pay to the relevant Governmental Authority, any Taxes with respect to all Pre-Closing Pass-Through Tax Returns.

(ii) Pre-Effective Time Tax Returns. Magellan will cause to be prepared all Tax Returns of the Companies for all Tax Periods ending on or before the Effective Time (other than Pre-Closing Pass-Through Tax Returns) (each, a “Pre-Effective Time Tax Return”). At least 30 days prior to the due date for filing any such Pre-Effective Time Tax Return, Magellan will deliver a copy of such Pre-Effective Time Tax Return, together with all supporting documentation and workpapers, to One Stone for its review and comment. Magellan will revise such Pre-Effective Time Tax Return to reflect any reasonable comments received from One Stone and, not later than five days prior to the due date for filing such Pre-Effective Time Tax Return, will provide such revised Pre-Effective Time Tax Return to One Stone (executed, as may be required, by any present or former authorized owners or officers of the applicable Company). The Parties shall cause the relevant Company to timely file such Tax Return (as revised to incorporate the One Stone’s reasonable comments) with and pay the amount of Taxes shown as due thereon to the appropriate Governmental Authority and provide a copy of such Tax Return and any receipt of payment to each of the Parties. Not later than five days prior to the due date for payment of Taxes with respect to such Pre-Effective Time Tax Return, Magellan will pay to (or at the direction of) One Stone the amount of Taxes shown as due on such Pre-Effective Time Tax Return; provided, however, that in the case of Utah CO2, Magellan shall only be required to pay to One Stone an amount equal to 51% of such Taxes.

(iii) Straddle Period Tax Returns. One Stone will prepare or cause to be prepared all Tax Returns of the Companies for all Straddle Periods (each, a “Straddle Tax Return”). Not later

than 30 days prior to the due date for filing any such Straddle Tax Return (other than Tax Returns for sales tax, use tax, payroll tax or social security or other Tax Returns that are due simultaneously with or soon after the end of the Tax Period), One Stone will deliver a draft of such Straddle Tax Return, together with all supporting documentation and workpapers, to Magellan for Magellan’s review and comment. The Parties shall cause the relevant Company to timely file such Straddle Tax Return (as revised to incorporate the Magellan’s reasonable comments) with and pay the amount of Taxes shown as due thereon to the appropriate Governmental Authority and provide a copy of such Tax Return and any receipt of payment to each of the Parties. Not later than five days prior to the due date for payment of Taxes with respect to such Straddle Tax Return, Magellan will pay to (or at the direction of) One Stone the amount of Taxes allocable to the portion of such Straddle Period ending immediately prior to the Effective Time (as determined pursuant to Section 4.9(b)(i); provided, however, that in the case of Utah CO2, Magellan shall only be required to pay to One Stone an amount equal to 51% of such Taxes.

(iv) No Duplication. Notwithstanding any provision of the Agreement, payments and adjustments pursuant to this Section 4.9(a) and Annex 2 shall be made without duplication.

(b) Apportionment of Straddle Period Taxes.

(i) Property Taxes and other Taxes that are imposed on a periodic basis with respect to the assets or capital of any Company with respect to a Straddle Period shall be deemed attributable to the period during which ownership of the applicable property, assets or capital gives rise to liability for such Taxes, and liability therefor will be allocated to Magellan for the portion of any Straddle Period ending immediately prior to the Effective Time, and to One Stone for the portion of any Straddle Period beginning at the Effective Time. For purposes of determining the allocations described in this Section 4.9(b)(i), Taxes pertaining to a Straddle Period shall be allocated between the portion of such Straddle Period ending immediately prior to the Effective Time and the portion of such Straddle Period beginning at the Effective Time by prorating each such Tax based on the number of days in the applicable Straddle Period that occur before the date on which the Effective Time occurs, on the one hand, and the number of days in such Straddle Period that occur on or after the date on which the Effective Time occurs, on the other hand.

(ii) Severance Taxes with respect to a Straddle Period shall be deemed attributable to the period during which the Production of the Hydrocarbons with respect to such Severance Taxes occurred, and liability therefor shall be allocated to Magellan for the portion of such Straddle Period ending immediately prior to the Effective Time and One Stone for the portion of such Straddle Period beginning at the Effective Time based upon the relative amount of Production of Hydrocarbons with respect to such Severance Tax that occurred during each such portion of the Straddle Period.

(iii) In the case of Income Taxes with respect to a Straddle Period or other Taxes of a Company with respect to a Straddle Period that are either (A) based upon or related to income or receipts, or (B) imposed in connection with any sale or other transfer or assignment of property

(real or personal, tangible or intangible), the amount of such Taxes treated as allocable to the portion of the Straddle Period ending immediately prior to the Effective Time shall be deemed equal to the amount that would be payable if the Tax Period of the Company ended immediately prior to the Effective Time; provided that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between Magellan for the portion of the Straddle Period ending on the day immediately prior to the date on which the Effective Time occurs and One Stone for the portion of the Straddle Period beginning on the day on which the Effective Time occurs based on the proportion to the number of days in each portion of the period.

(iv) To the extent the actual amount of a Tax is not determinable at the time an adjustment to the Cash Amount is to be made with respect to such Tax pursuant to Annex 2, (A) the Parties shall utilize the most recent information available in estimating the amount of such Tax for purposes of such adjustment, and (B) upon the later determination of the actual amount of such Tax, timely payments will be made from one Party to the others to the extent necessary to cause each Party to bear the amount of such Tax that is allocable to such Party under this Section 4.9(b)(i).

(c) Tax Refunds. Magellan shall be entitled to all rights to any refunds of Taxes of the Companies allocable to a Tax Period or portion thereof ending prior to the Effective Time and paid or otherwise economically borne by Magellan. One Stone shall be entitled to all rights to any refunds of any other Taxes of the Companies. If a Party or any of its Affiliates receives a refund of Taxes to which the other Parties are entitled pursuant to this Section 4.9(c), such receiving Party shall forward to the other Parties the amount of such refund within thirty (30) days after such refund is received, net of any reasonable costs or expenses incurred by such receiving Party in procuring such refund. If any refund on account of which a payment was made pursuant to this Section 4.9(c) is subsequently reduced or disallowed, the Party that received such payment shall indemnify and hold harmless the Party making such payment (and its Affiliates) from and against any loss that is attributable to such reduction or disallowance.

(d) Transfer Taxes. The Parties do not anticipate that any Transfer Taxes will be due with respect to the transactions contemplated by this Agreement, but if Transfer Taxes are due, responsibility for such Taxes be governed by this Section 4.9(d). Notwithstanding any requirement of Law, and notwithstanding anything else to the contrary in this Agreement, any and all Transfer Taxes required to be paid in connection with transactions contemplated by this Agreement shall be paid 50% by One Stone and 50% by Magellan. One Stone shall timely file all Tax Returns required to be filed in respect of Transfer Taxes and shall remit such Transfer Taxes to the appropriate Governmental Authority, and Magellan shall reimburse One Stone for its share of such Transfer Taxes. Magellan and One Stone shall reasonably cooperate with each other to share information reasonably needed for the preparation and filing of Tax Returns and other documentation relating to Transfer Taxes as may be required by Applicable Law and to mitigate, reduce or eliminate any Transfer Taxes required to be paid in connection with the transactions contemplated by this Agreement.

(e) Cooperation on Tax Matters. On and after the date of this Agreement, each Party shall:

(i) reasonably cooperate and assist the other (A) in preparing any Tax Returns relating to any Tax relating to the Companies or their Properties, and (B) in qualifying for any exemption or reduction in Tax that may be available;

(ii) reasonably cooperate in preparing for any audits, examinations or other Tax proceedings by, or disputes with, any Taxing Authority regarding any Tax of the Companies or their Properties;

(iii) make available to the other, and to any Taxing Authority as reasonably requested, any information, records, and documents relating to a Tax incurred or imposed on the Company or in connection with the Poplar Properties;

(iv) to the extent that a pending or threatened Tax audit, examination, or assessment (a “Tax Controversy”) could reasonably be expected to affect another Party’s Tax liability under Applicable Law or this Agreement: (A) provide timely notice to such other Party in writing thereof, (B) promptly furnish such other Party with copies of all material correspondence with respect to any Tax Controversy, (C) allow such other Party to participate, at their own expense, in any Tax Controversy, and (D) not settle any Tax Controversy without the prior written consent of such other Party, which may not be unreasonably withheld, conditioned or delayed.

(f) Tax Structuring and Elections. As, when and to the extent requested by One Stone, Magellan will undertake any or all of the following actions: (i) form a new Delaware limited liability company (“Newco”), contribute the CO2 Business to Newco, and in lieu of transferring the CO2 Business to One Stone, transfer Newco to One Stone; (ii) avoid taking any action that would cause Newco to be included in any combined, consolidated or unitary group for Tax purposes with Magellan or any of its Subsidiaries or Affiliates; (iii) cause Newco to file an initial election pursuant to Treasury Regulation Section 301.7701-3 to cause Newco to be classified as an association taxable as a corporation effective from its date of formation; (iv) timely take any and all actions reasonably necessary or requested to make a valid and binding election (or a protective election) under Section 362(e)(2)(C) of the Code and the Treasury Regulations promulgated thereunder with respect to the contribution of the CO2 Business to Newco; (v) if One Stone reasonably determines that the Exchange qualifies as a distribution under Section 355 of the Code, timely take any and all reasonably necessary or requested actions in support of such Tax treatment; and (vi) take any and all other actions reasonably necessary or requested that are incidental or otherwise related to any of the foregoing. To the extent this Section 4.9(f) is applicable, Magellan shall file all Tax Returns and otherwise report consistently with the Tax positions described in this Section 4.9(f) and shall not take any action that is inconsistent with any such Tax positions, except to the extent otherwise required by a final determination (as such term is defined in Section 1313 of the Code).

(g) Limited Operations of Newco. If Magellan forms Newco at the request of One Stone pursuant to Section 4.9(f), Magellan shall not cause or permit Newco to conduct any business operations, incur any liabilities or obligations other than those incident to its formation or arising as a result of any of the actions taken at the request of One Stone pursuant to Section 4.9(f).

Section 4.10 One Stone Voting Agreement. One Stone has taken all lawful steps necessary to approve the Exchange and agrees during the term of this Agreement not to reverse or supersede its previous approval of the Exchange. One Stone shall not take any action that could reasonably be expected to impede, interfere with, delay, discourage, adversely affect or inhibit the timely consummation of the Exchange or the fulfillment of the conditions under this Agreement. One Stone will vote all shares of the Preferred Stock in favor of the proposal to approve the Exchange at the Magellan Stockholder Meeting. One Stone will not, directly or indirectly, transfer, sell, offer, exchange, assign, pledge or otherwise dispose of or encumber (“Transfer”) any of its interests in the Preferred Stock or enter into any contract, option or other agreement with respect to, or consent to, a Transfer of, any of the Preferred Stock or One Stone’s voting or economic interest therein. Any attempted Transfer of the Preferred Stock or any interest therein in violation of this Section 4.10 shall be null and void.

Section 4.11 Secured Promissory Note; Pledge Agreement. By April 15, 2016, One Stone and Magellan shall (a) enter into a Secured Promissory Note in substantially the form set forth on Annex 5 (the “Secured Promissory Note”), pursuant to which One Stone agrees to make a loan to Magellan in the aggregate amount of $625,000 (the “Loan Amount”) in accordance with the terms and conditions set forth therein and (b) simultaneously enter into a Pledge Agreement in substantially the form set forth on Annex 6 (the “Pledge Agreement”), pursuant to which Magellan will pledge, assign and grant to One Stone a security interest in certain assets of Magellan as described therein.

Section 4.12 Certain Employees. At Closing, the Persons listed in Annex 3 shall resign as employees of Magellan, and One Stone, or an Affiliate thereof, may make an offer of employment to such Persons, provided, however, that terms and conditions of such offer shall be determined by One Stone, or an Affiliate thereof, in its sole discretion.

Section 4.13 BOLO Data. For the period beginning with the Closing Date and ending 60 days after the Closing Date, Magellan shall reasonably cooperate in providing One Stone with the BOLO data used by Magellan to manage the Poplar Properties.

Section 4.14 One Stone Release. Effective as of the Closing, subject to the last sentence of this Section 4.14, One Stone hereby releases and discharges, and will cause Poplar and Utah CO2 to discharge and release, Magellan from any and all contractual obligations (including indemnification obligations) associated with any contracts (including Material Contracts) in which Poplar or Utah CO2 is a party prior to the Closing Date, including the WTSB Loan. Magellan hereby (a) waives any preferential purchase right, right of first refusal, right of first offer, buy-sell right, tag-along right, drag-along right, preemptive right, registration right or other right that would interfere with execution of this Agreement and the consummation of the transactions contemplated hereby or any future transfers of any Interest in Poplar or Utah CO2, including any such rights arising under any provision of the Poplar Organizational Documents and the Utah CO2 Organizational Documents and (b) agrees that the transfer of the CO2 Business contemplated by this Agreement is not void or voidable by reason of any restriction set forth in the Poplar Organizational Documents or the Utah CO2 Organizational Documents. Notwithstanding the foregoing or anything in this Agreement to the contrary, One Stone does not release or discharge any obligations or waive any rights

arising under this Agreement or any certificate(s) delivered by One Stone at the Closing of the transactions contemplated hereby.

(ii) if Magellan shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of Magellan set forth in this Agreement shall fail to be true), which breach or failure (A) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 5.3(a) or Section 5.3(b) and (B) is incapable of being cured, or is not cured, by Magellan by the earlier of thirty (30) days following receipt of written notice from One Stone of such breach or failure or the Outside Date; provided that One Stone shall not have the right to terminate this Agreement pursuant to this Section 6.1(c)(ii) if One Stone is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement such as would result in any of the closing conditions set forth in Section 5.2(a) and Section 5.2(b) not being satisfied.

(a) Preliminary Settlement Statement. The preliminary Net Revenues and Expenses shall be set out in a “Preliminary Settlement Statement” prepared by Magellan in good faith and submitted to One Stone no later than five (5) Business Days prior to the Closing Date. The Preliminary Settlement Statement shall set forth the Net Revenues and Expenses, as adjusted, as provided in Section 3 of this Annex 2 using the best information available at the Closing Date, and the Cash Amount, in each case as calculated in accordance with GAAP and Council of Petroleum Accountants Society standards.

As soon as practicable after the Closing, but in no event later than ninety (90) days after Closing, One Stone, with the assistance of Magellan’s staff and with access to such records as necessary, will cause to be prepared and delivered to Magellan, in each case calculated in accordance with GAAP and Council of Petroleum Accountants Society standards, the final settlement statement (the “Final Settlement Statement”) setting forth each adjustment to Net Revenues and Expenses in accordance with Section 3 of this Annex 2 and showing the calculation of such adjustments and the resulting final Cash Amount (the “Final Cash Amount”). Within fifteen (15) days after receipt of such statement, Magellan shall deliver to One Stone a written report containing any changes that Magellan proposes to make to the Final Settlement Statement. Magellan’s failure to deliver to One Stone a written report detailing proposed changes to the Final Settlement Statement by that date shall be deemed an acceptance by Magellan of the Final Settlement Statement as submitted by One Stone. The Parties shall use commercially reasonable efforts to agree with respect to the changes proposed by Magellan, if any, no later than fifteen (15) days after Magellan’s receipt of One Stone’s proposed Final Settlement Statement. The date upon which such agreement is reached or upon which the Final Cash Amount is established shall be herein called the “Final Settlement Date.” If the Final Cash Amount is less than the Cash Amount, One Stone shall pay the amount of such difference to Magellan by wire transfer in immediately available funds no later than five (5) Business Days after the Final Settlement Date. If the Final Cash Amount is more than the Cash Amount, Magellan shall pay to One Stone the amount of such difference by wire transfer in immediately available funds no later than five (5) Business Days after the Final Settlement Date.

(c) Dispute Resolution. If the Parties are unable to resolve a dispute as to the Final Cash Amount within thirty (30) days after One Stone’s receipt of Magellan’s proposed revised Final Settlement Statement, the Parties shall submit the dispute to binding arbitration to be conducted in accordance with the provisions of Section 5 of this Annex 2.

5. Dispute Resolution and Arbitration. Any dispute between the Parties as to the Final Cash Amount shall be resolved by arbitration, pursuant to the following procedures:

(a) Magellan, on the one hand, and One Stone, on the other hand, shall each select a single, independent arbitrator with at least ten (10) years’ experience practicing oil and gas law in the State of Montana, within ten (10) days after written demand for such arbitration by any Party.

(b) The arbitration shall be governed by, and construed in accordance with, the laws of the State of Delaware, applicable to contracts executed in and to be performed entirely within that State, but the specific procedure to be followed shall be determined by mutual agreement of Magellan and One Stone, failing which it shall be determined by the arbitrator(s). It is the intent of the Parties that the arbitration be conducted as efficiently and inexpensively as possible, with only limited

discovery as determined by the arbitrator without regard to the discovery permitted under the Delaware or Federal Rules of Civil Procedure.

(c) The arbitration proceeding shall be held in Denver, Colorado, and the arbitration hearing shall be held no later than sixty (60) days after submission of the matter to arbitration, and a written decision shall be rendered by the arbitrators within thirty (30) days of the hearing.

The Company hereby agrees that (i) it is the indemnitor of first resort (i.e., its obligations to the Indemnitees are primary and any obligation of the Other Sources to provide indemnification for the same Indemnified Liabilities are secondary to any such obligation of the Company), (ii) that it shall be liable for the full amount of all Indemnified Liabilities, without regard to any rights the Indemnitees may have against the Other Sources, and (iii) it irrevocably waives, relinquishes and releases the Other Sources and the Indemnitees from any and all claims (x) against the Other Sources for contribution, indemnification, subrogation or any other recovery of any kind in respect thereof except to the extent the underlying Indemnified Liabilities arise primarily from the gross negligence or willful misconduct of such Other Source as determined by a court of competent jurisdiction in a final, nonappealable order and (y) that an Indemnitee must seek expense advancement or reimbursement, or indemnification, from the Other Sources before the Company must perform its obligations hereunder. No advancement or payment by the Other Sources on behalf of an Indemnitee

with respect to any claim for which such Indemnitee has sought indemnification from the Company shall affect the foregoing. The Other Sources shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery which the Indemnitee would have had against the Company if the Other Sources had not advanced or paid any amount to or on behalf of the Indemnitee, except to the extent the underlying Indemnified Liabilities arise primarily from the gross negligence or willful misconduct of such Other Source as determined by a court of competent jurisdiction in a final, nonappealable order.

5.4 Entire Agreement.

(iii)The Grantor shall be entitled to collect and receive for its own use all cash dividends and interest paid in respect of the Pledged Collateral owned by it; provided, however, if an Event of Default exists, the Grantor shall not be able to retain any of the following distributions and payments: (A) dividends and interest paid or payable other than in cash in respect of such Pledged

Collateral, and instruments and other property received, receivable or otherwise distributed in respect of, or in exchange for, any Pledged Collateral; (B) dividends and other distributions paid or payable in cash in respect of such Pledged Collateral in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital, capital surplus or paid-in capital of an issuer; and (C) cash paid, payable or otherwise distributed, in respect of principal of, or in redemption of, or in exchange for, such Pledged Collateral; provided further, that until actually paid, all rights to such distributions shall remain subject to the Lien created by this Agreement (all such distributions and payments permitted under this subsection 4.4(c)(iii), collectively, the “Excluded Payments”); and

(iv)All distributions in respect of any of the Pledged Collateral owned by the Grantor, whenever paid or made, other than Excluded Payments made in accordance with Section 4.4(c)(iii), shall be delivered to the Holder to hold as Pledged Collateral if an Event of Default exists and shall, if received by the Grantor while an Event of Default exists, be received in trust for the benefit of the Holder, be segregated from the other property or funds of the Grantor, and be forthwith delivered to the Holder as Pledged Collateral in the same form as so received (with any necessary endorsement).

5.5. No Interference. The Grantor agrees that it will not interfere with any right, power and remedy of the Holder provided for in this Agreement or, during the continuance of an Event of Default, now or hereafter existing at law or in equity or by statute or otherwise, or the valid exercise or beginning of the valid exercise by the Holder of any one or more of such rights, powers or remedies.

ARTICLE V

EVENTS OF DEFAULT AND REMEDIES

(i)those rights and remedies provided in this Agreement, the Note, or any other Note Document; provided that, this Section 5.2(a) shall not be understood to limit any rights or remedies expressly made available to the Holder prior to an Event of Default in this Agreement, the Note or any other Note Document;

(c)The Holder shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, in each case during the existence of an Event of Default, to purchase for the benefit of the Holder, the whole or any part of the Collateral so sold, free of any right of equity redemption, which equity redemption the Grantor hereby expressly releases.

(d)Until the Holder is able to affect a sale, lease, or other disposition of Collateral during the existence of an Event of Default, the Holder shall have the right to hold or use Collateral, or any part thereof, to the extent that it deems appropriate for the purpose of preserving Collateral or its value or for any other purpose deemed appropriate by the Holder. The Holder may, if it so elects during the existence of an Event of Default, seek the appointment of a receiver or keeper to take possession of Collateral and to enforce any of the Holder’s remedies, with respect to such appointment without prior notice or hearing as to such appointment.

(e)Notwithstanding the foregoing, the Holder shall not be required to (i) make any demand upon, or pursue or exhaust any of its rights or remedies against, the Grantor, any other obligor, guarantor, pledgor or any other Person with respect to the payment of the Obligations or to pursue or exhaust any of its rights or remedies with respect to any Collateral therefor or any direct or indirect guarantee thereof, (ii) marshal the Collateral or any guarantee of the Obligations or to resort to the Collateral or any such guarantee in any particular order, or (iii) effect a public sale of any Collateral.

(f)The Grantor recognizes that the Holder may be unable to effect a public sale of any or all the Holder and may be compelled to resort to one or more private sales thereof in accordance with Section 5.2(a). The Grantor also acknowledges that any private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall not be deemed to have been made in a commercially unreasonable manner solely by virtue of such sale being private. The Holder shall be under no obligation to delay a sale of any of the Holder for the period of time necessary to permit the Grantor or the issuer of the Holder to register such securities for public sale under the Securities Act of 1933, as amended, or under applicable state securities laws, even if the Grantor and the issuer would agree to do so.

5.3. Grantor’s Obligations Upon Default. Upon the request of the Holder after the occurrence and during the continuance of an Event of Default, the Grantor will:

(a)assemble and make available to the Holder the Collateral and all books and records relating thereto at any place or places reasonably specified by the Holder, whether at the Grantor’s premises or elsewhere;

(b)permit the Holder, by the Holder’s representatives and agents, to enter, occupy and use any premises where all or any part of the Collateral, or the books and records relating thereto, or both, are located, to take possession of all or any part of the Collateral or the books and records relating thereto, or both, to remove all or any part of the Collateral or the books and records relating thereto, or both, and to conduct sales of the Collateral, without any obligation to pay the Grantor for such use and occupancy;

(c)prepare and file, or cause an issuer of Pledged Collateral (if such issuer is Controlled by a Grantor) to prepare and file, with the Securities and Exchange Commission or any other applicable government agency, registration statements, a prospectus and such other documentation in connection with the Pledged Collateral as the Holder may request, all in form and substance satisfactory to the Holder, and furnish to the Holder, or cause an issuer of Pledged Collateral (if such issuer is Controlled by a Grantor) to furnish to the Holder, any information regarding the Pledged Collateral in such detail as the Holder may specify; and

(d)take, or cause an issuer of Pledged Collateral (if such issuer is Controlled by a Grantor) to take, any and all actions necessary to register or qualify the Pledged Collateral to enable the Holder to consummate a public sale or other disposition of the Pledged Collateral.

ARTICLE VI

ACCOUNT VERIFICATION; ATTORNEY IN FACT; PROXY

(a) The Grantor irrevocably authorizes the Holder at any time and from time to time in the sole discretion of the Holder and appoints the Holder as its attorney in fact (i) to execute on behalf of the Grantor as debtor and to file financing statements necessary or appropriate in the Holder’s reasonable discretion to perfect and to maintain the perfection and priority of the Holder’s security interest in the Collateral, (ii) to endorse and collect any cash proceeds of the Collateral during the existence of an Event of Default, (iii) to file a carbon, photographic or other reproduction of this Agreement or any financing statement with respect to the Collateral as a financing statement and to file any other financing statement or amendment of a financing statement (which does not add new collateral or add a debtor) in such offices as the Holder in its reasonable discretion deems necessary or appropriate to perfect and to maintain the perfection and priority of the Holder’s security interest in the Collateral, (iv) to contact and enter into one or more agreements with the issuers of uncertificated securities which are Pledged Collateral or with securities intermediaries holding Pledged Collateral as may be necessary to give the Holder Control over such Pledged Collateral, (v) to discharge past due taxes, assessments, charges, fees or Liens on the Collateral (except for such Liens as are specifically permitted hereunder) during the existence of an Event of Default, and (vi) to do all other acts and things necessary to carry out the terms of this Agreement during the existence of an Event of Default; and the Grantor agrees to reimburse the Holder within ten (10) days after written demand for any reasonable payment made or any reasonable out-of-pocket expense incurred by the Holder in connection with any of the foregoing; provided that, this authorization shall not relieve the Grantor of any of its obligations under this Agreement, the Note or under any other Note Document.

(b) All lawful acts of said attorney or designee are hereby ratified and approved. The powers conferred on the Holder under this Section 6.1 are solely to protect the Holder’s interests in the Collateral and shall not impose any duty upon the Holder to exercise any such powers.

6.2. PROXY. THE GRANTOR HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS THE HOLDER AS ITS PROXY AND ATTORNEY‑IN‑FACT (AS SET FORTH IN SECTION 6.1 ABOVE) WITH RESPECT TO ITS PLEDGED COLLATERAL, INCLUDING THE RIGHT TO VOTE SUCH PLEDGED COLLATERAL, WITH FULL POWER OF SUBSTITUTION TO DO SO WHILE AN EVENT OF DEFAULT EXISTS. IN ADDITION TO THE RIGHT TO VOTE ANY SUCH PLEDGED COLLATERAL WHILE AN EVENT OF DEFAULT EXISTS, THE APPOINTMENT OF THE HOLDER AS PROXY AND ATTORNEY-IN-FACT SHALL INCLUDE THE RIGHT TO EXERCISE ALL OTHER RIGHTS, POWERS, PRIVILEGES AND REMEDIES TO WHICH A HOLDER OF SUCH PLEDGED COLLATERAL WOULD BE ENTITLED (INCLUDING GIVING OR WITHHOLDING WRITTEN CONSENTS OF SHAREHOLDERS, CALLING SPECIAL MEETINGS OF SHAREHOLDERS AND VOTING AT SUCH MEETINGS) WHILE AN EVENT OF DEFAULT EXISTS. SUCH PROXY SHALL BE EFFECTIVE, AUTOMATICALLY AND WITHOUT THE NECESSITY OF ANY ACTION (INCLUDING ANY TRANSFER OF ANY SUCH PLEDGED COLLATERAL ON THE RECORD BOOKS OF THE ISSUER THEREOF) BY ANY PERSON (INCLUDING THE ISSUER OF SUCH PLEDGED COLLATERAL OR ANY OFFICER OR AGENT THEREOF), UPON THE OCCURRENCE AND DURING THE CONTINUANCE OF AN EVENT OF DEFAULT.

6.3. NATURE OF APPOINTMENT; LIMITATION OF DUTY. THE APPOINTMENT OF THE HOLDER AS PROXY AND ATTORNEY-IN-FACT IN THIS ARTICLE VI IS COUPLED WITH AN INTEREST AND SHALL BE IRREVOCABLE UNTIL THE TERMINATION DATE. NOTWITHSTANDING ANYTHING CONTAINED HEREIN, NEITHER THE HOLDER NOR ANY OF ITS RESPECTIVE AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR REPRESENTATIVES SHALL HAVE ANY DUTY TO EXERCISE ANY RIGHT OR POWER GRANTED HEREUNDER OR OTHERWISE OR TO PRESERVE THE SAME AND SHALL NOT BE LIABLE FOR ANY FAILURE TO DO SO OR FOR ANY DELAY IN DOING SO, EXCEPT IN RESPECT OF DAMAGES ATTRIBUTABLE SOLELY TO THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT AS FINALLY DETERMINED BY A COURT OF COMPETENT JURISDICTION; PROVIDED THAT, IN NO EVENT SHALL THEY BE LIABLE FOR ANY PUNITIVE, EXEMPLARY, INDIRECT OR CONSEQUENTIAL DAMAGES.

ARTICLE VII

GENERAL PROVISIONS

7.1.Waivers. To the extent permitted by applicable law, the Grantor hereby waives notice of the time and place of any public sale or the time after which any private sale or other disposition of all or any part of the Collateral may be made. To the extent such notice may not be waived under applicable law, any notice made shall be deemed reasonable if sent to the Grantor, addressed as set forth in Article VIII, at least ten (10) days prior to (a) the date of any such public sale or (b) the time after which any such private sale or other disposition may be made. To the maximum extent permitted by applicable law, the Grantor waives all claims, damages, and demands against the Holder arising out of the repossession, retention or sale of the Collateral, except such as arise solely out of the gross negligence or willful misconduct of the Holder as finally determined by a court of competent jurisdiction. To the extent it may lawfully do so, the Grantor absolutely and irrevocably waives and relinquishes the benefit and advantage of, and covenants not to assert against the Holder, any valuation, stay, appraisal, extension, moratorium, redemption or similar laws and any and all rights or defenses it may have as a surety now or hereafter existing which, but for this provision, might be applicable to the sale of any Collateral made under the judgment, order or decree of any court, or privately under the power of sale conferred by this Agreement, or otherwise. Except as otherwise specifically provided herein or in any other Note Document, the Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by applicable law) of any kind in connection with this Agreement or any Collateral.

7.2.Limitation on the Holder’s Duty with Respect to the Collateral. The Holder shall have no obligation to clean-up or otherwise prepare the Collateral for sale. The Holder shall use reasonable care with respect to the Collateral in its possession or under its Control. The Holder shall not have any other duty as to any Collateral in its possession or Control or in the possession or Control of any agent or nominee of the Holder, or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto. To the extent that applicable law imposes duties on the Holder to exercise remedies in a commercially reasonable manner, the Grantor acknowledges and agrees that it is commercially reasonable for the Holder (a) to fail to incur expenses deemed significant by the Holder to prepare Collateral for disposition, (b) to advertise dispositions of Collateral through publications or media of general circulation,

whether or not the Collateral is of a specialized nature, (c) to contact other Persons, whether or not in the same business as the Grantor, for expressions of interest in acquiring all or any portion of such Collateral, (d) to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, (e) to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, or (f) to the extent deemed appropriate by the Holder, to obtain the services of brokers, investment bankers, consultants and other professionals to assist the Holder in the collection or disposition of any of the Collateral. The Grantor acknowledges that the purpose of this Section 7.2 is to provide non-exhaustive indications of what actions or omissions by the Holder would be commercially reasonable in the Holder’s exercise of remedies against the Collateral and that other actions or omissions by the Holder shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 7.2. Without limitation upon the foregoing, nothing contained in this Section 7.2 shall be construed to grant any rights to the Grantor or to impose any duties on the Holder that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section 7.2.

7.3.Holder Performance of Debtor Obligations. Without having any obligation to do so, the Holder may perform or pay any obligation which the Grantor has agreed to perform or pay in this Agreement if the Grantor fails to perform or pay such obligation to the extent it constitutes an Event of Default, and the Grantor shall reimburse the Holder for any reasonable amounts paid by the Holder pursuant to this Section 7.3. The Grantor’s obligation to reimburse the Holder pursuant to the preceding sentence shall be Obligations payable on demand.

7.4.Specific Performance of Certain Covenants. The Grantor acknowledges and agrees that a breach of any of the covenants contained herein will cause irreparable injury to the Holder, that the Holder has no adequate remedy at law in respect of such breaches and therefore agrees that the covenants of the Grantor contained herein shall be specifically enforceable against the Grantor.

7.5.Dispositions Not Authorized. The Holder hereby acknowledges and agrees that the Grantor is authorized to sell, assign, transfer, distribute, dividend, exchange or otherwise dispose of the Collateral except to the extent expressly set forth in Section 4.1(d), but notwithstanding any course of dealing between the Grantor and the Holder or other conduct of the Holder, no authorization to sell, assign, transfer, distribute, dividend, exchange or otherwise dispose of any Central Shares or any Equity Interests in Magellan Petroleum Australia owned by Grantor shall be binding upon the Holder unless such authorization by the Holder is in writing.

7.6.No Waiver; Amendments; Cumulative Remedies. No delay or omission of the Holder to exercise any right or remedy granted under this Agreement shall impair such right or remedy or be construed to be a waiver of any Default or an acquiescence therein, and any single or partial exercise of any such right or remedy shall not preclude any other or further exercise thereof or the exercise of any other right or remedy. No waiver, amendment or other variation of the terms, conditions or provisions of this Agreement whatsoever shall be valid unless in writing signed by the Holder and then only to the extent in such writing specifically set forth. All rights and remedies contained in this Agreement or by law afforded shall be cumulative and all shall be available to the Holder until the Termination Date.

7.7.Limitation by Law; Severability of Provisions. All rights, remedies and powers provided in this Agreement may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law, and all the provisions of this Agreement are intended to be subject to all applicable mandatory provisions of law that may be controlling and to be limited to the extent necessary so that they shall not render this Agreement invalid, unenforceable or not entitled to be recorded or registered, in whole or in part. Any provision in this Agreement that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of this Agreement are declared to be severable.

7.8.Reinstatement. This Agreement shall remain in full force and effect and continue to be effective should any petition be filed by or against the Grantor for liquidation or reorganization, should the Grantor become insolvent or make an assignment for the benefit of any creditor or creditors or should a receiver or trustee be appointed for all or any significant part of the Grantor’s assets, and shall continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Obligations, or any part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee of the Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

7.9.Benefit of Agreement. The terms and provisions of this Agreement shall be binding upon and inure to the benefit of the Grantor and the Holder and their respective successors and assigns (including all persons who become bound as a debtor to this Agreement), except that the Grantor shall not have the right to assign its rights or delegate its obligations under this Agreement or any interest herein, without the prior written consent of the Holder. No sales of participations, assignments, transfers, or other dispositions of any agreement governing the Obligations or any portion thereof or interest therein shall in any manner impair the Lien granted to the Holder hereunder.

7.10.Survival of Representations. All representations and warranties of the Grantor contained in this Agreement shall survive the execution and delivery of this Agreement.

7.11.Headings. The title of and section headings in this Agreement are for convenience of reference only, and shall not govern the interpretation of any of the terms and provisions of this Agreement.

7.12.Termination; Release.

(a) This Agreement shall continue in effect (notwithstanding the fact that from time to time there may be no Obligations outstanding) until (such occurrence being the “Termination Date”) the earlier of (i) the time at which all of the Obligations have been paid in full (other than any contingent obligations not then due and indemnification obligations not then due) and (ii) the consummation of the Exchange Agreement Closing. Upon the occurrence of the Termination Date, the Holder shall forthwith cause the satisfaction, discharge and termination of this Agreement and the Liens granted hereunder (subject

to Section 7.8) and shall prepare and record any and all termination statements as may be appropriate to terminate all financing statements and other filings made in connection with the Liens granted hereunder.

(b) If any of the Collateral shall be sold, transferred or otherwise disposed of by the Grantor in a transaction permitted by this Agreement or the Note, the security interest created hereby in any Collateral that is so sold, transferred or otherwise disposed of shall automatically terminate and be released upon the closing of such sale, transfer or other disposition, and such Collateral shall be sold free and clear of the Lien and security interest created hereby; provided that, to the extent required by this Agreement or the Note, the Holder shall have consented to such sale, transfer or other disposition; provided, further, that such security interest will continue to attach to all proceeds of such sales, transfers or other dispositions except to the extent such proceeds are the subject of any such sale, assignment, transfer or disposition or as otherwise consented to by Holder.

(c) In connection with any of the foregoing, the Holder shall execute and deliver to the Grantor or the Grantor’s designee, at the Grantor’s expense, all UCC termination statements and similar documents that the Grantor shall reasonably request from time to time to evidence such termination. Any execution and delivery of termination statements or documents pursuant to this Section 7.12 shall be without recourse to or warranty by the Holder.

7.13.Entire Agreement. This Agreement (together with the other Note Documents) embodies the entire agreement and understanding between the Grantor and the Holder relating to the Collateral and supersedes all prior agreements and understandings between the Grantor and the Holder relating to the Collateral.

7.14.CHOICE OF LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

7.15.CONSENT TO JURISDICTION. ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER NOTE DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, IN EITHER CASE LOCATED IN NEW YORK COUNTY, NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE GRANTOR HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. THE GRANTOR HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE THE HOLDER FROM OBTAINING JURISDICTION OVER THE GRANTOR IN ANY COURT OTHERWISE HAVING JURISDICTION. THE GRANTOR IRREVOCABLY AGREES THAT ANY LEGAL PROCEEDING AGAINST THE HOLDER OR ANY AFFILIATE OF THE HOLDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS AGREEMENT OR ANY OTHER NOTE DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF

NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK LOCATED, IN EITHER CASE, IN NEW YORK COUNTY, NEW YORK.

7.16.WAIVER OF JURY TRIAL. THE GRANTOR AND THE HOLDER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS AGREEMENT OR ANY OTHER NOTE DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

7.17.Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart.

7.18.Lien Absolute. All obligations of the Grantor hereunder shall be absolute and unconditional irrespective of:

(a) any extension, renewal, settlement, compromise, waiver or release in respect of any of the Obligations, by operation of law or otherwise, or any obligation of any other guarantor of any of the Obligations, or any default, failure or delay, willful or otherwise, in the payment or performance of the Obligations;

(b) any lack of validity or enforceability relating to or against the Grantor or any other guarantor of any of the Obligations, for any reason related to the Note, any other Note Document or any other agreement or instrument governing or evidencing any Obligations, or any governmental requirements purporting to prohibit the payment by the Grantor or any other guarantor of the Obligations of the principal of or interest on the Obligations;

(d) any change in the time, manner or place of payment of, or in any other term of, all or any part of the Obligations, or any other amendment or waiver of or any consent to any departure from the Note, any other Note Document or any other agreement or instrument governing or evidencing any Obligations, including any increase or decrease in the rate of interest thereon;

(e) any change in the corporate existence, structure or ownership of the Grantor or any other guarantor of any of the Obligations, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Grantor or any other guarantor of the Obligations, or any of their assets or any resulting release of discharge of any obligation of the Grantor or any other guarantor or any of the Obligations;

(f) any present or future law, regulation or order of any jurisdiction (whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of any Note Document or Obligations;

(g) any other setoff, defense (other than payment in full of the Obligations) or counterclaim whatsoever (in any case, whether based on contract, tort or any other theory) with respect to the Note, any other Note Document, any other agreement or instrument or the transactions contemplated thereby which might constitute a legal or equitable defense available to, or discharge of the Grantor; or

(h) any other act or omission to act or delay of any kind by the Grantor, any other guarantor of the Obligations, the Holder or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the Grantor’s obligations hereunder.

7.19.Release. The Grantor consents and agrees that the Holder may at any time, or from time to time, in its discretion:

(a) renew, extend or change the time of payment, and/or the manner, place or terms of payment of all or any part of the Obligations in accordance with the terms of the Note; and
