3.2 Contract Area; Operating Agreements.

(a) On the Closing Date, the Parties shall execute and deliver (i) a joint operating agreement (the “Gasco Operating Agreement”), which shall cover all Leases and related assets in the Gasco Contract Area in which the Parties hold interests as of the Closing Date or in which the Parties hereafter both acquire interests in accordance with Article VII and (ii) a joint operating agreement (the “Wapiti Operating Agreement”), which shall cover all Leases and related assets in the Wapiti Contract Area in which the Parties hold interests as of the Closing Date or in which the Parties hereafter both acquire interests in accordance with Article VII.

If all of the third party working interest covered by a Third Party Operating Agreement is subsequently acquired by one or more of the Parties and/or their respective Affiliates, then such Third Party Operating Agreement shall be superseded and replaced in its entirety by the applicable Joint Operating Agreement (subject to the prevailing terms of this Agreement).

(c) Upon request by either Party, the Parties shall amend the applicable Joint Operating Agreement to reflect that such Joint Operating Agreement includes any Leases and related assets in the Contract Area in which the Parties hereafter both acquire interests in accordance with Article VII.

(d) As between the Parties, each Applicable Operating Agreement shall be subject to the provisions of the Tax Partnership Agreement, unless and until the applicability of such provisions to the Subject Interests terminates in accordance with the terms of the Tax Partnership Agreement.

3.3 Contract Operating Agreement. Concurrently with the execution and delivery of this Agreement, Wapiti, in its capacity as operator under certain Applicable Operating Agreements, and Gasco shall enter into a Contract Operating Agreement (the “Contract Operating Agreement”) attached as an Exhibit to the Purchase Agreement, whereby Gasco shall be named the contract operator in accordance with the terms thereof with respect to any Subject Interests covered by any Applicable Operating Agreement under which Wapiti is named operator.

(b) Prior to the end of the Drilling Term, the Parties shall be required to participate in the operations contemplated by the Drilling Program, and no Party shall have the right to make any nonconsent election under an Applicable Operating Agreement with respect to any operation contemplated by the Drilling Program. Further, subject to Article IX, Gasco is hereby authorized to propose to third parties and conduct all operations contemplated by the Drilling Program for the account of the Parties under the relevant Applicable Operating Agreement and the Contract Operating Agreement (provided that, to the extent any third party is a party to an Applicable Operating Agreement, Gasco shall propose an operation to such third party in accordance with the terms of the Applicable Operating Agreement, though, for the avoidance of doubt, the operation does not need to be re-proposed to the Parties).

(c) Subject to Article IX, Gasco shall be responsible for proposing to third parties, and conducting all operations that are contemplated by the Drilling Program under the Applicable Operating Agreement and the Contract Operating Agreement. Other than as provided in the preceding sentence and in Section 4.4, prior to the end of the Drilling Program, no Party or its Affiliates shall propose operations under any Applicable Operating Agreement; provided that, prior to the end of the Drilling Term, if Gasco fails to conduct any operation contemplated by the Drilling Program within the time periods prescribed for such operation under the Drilling Program, then notwithstanding the terms of this Agreement or the Contract Operating Agreement to the contrary, Wapiti shall be permitted to propose and conduct such operation.. Other than with respect to operations proposed by a third party under an Applicable Operating Agreement, Wapiti hereby authorizes Gasco on its behalf to provide such notices, make such elections required by the Drilling Program and take such actions as may reasonably be required under any Applicable Operating Agreement or any other Associated Agreement to implement the operations and activities provided for in the Drilling Program. To the extent that any elections or actions arise during the Drilling Program that are not contemplated by the Drilling Program, then, subject to Sections 4.2(d) and 4.4(c), any such elections or actions may only be taken by the Operating Committee. In the event that an operation is included in the Drilling Program is proposed under an Applicable Operating Agreement, and a third party to such Applicable Operating Agreement non-consents such proposal, then each Party shall be required to participate for its full share (as determined pursuant to Article V) of the Working Interest of such non-consenting third party and Gasco.

(d) If a third party proposes an operation pursuant to an Applicable Operating Agreement and such operation is expressly contemplated by the Drilling Program, then unless otherwise determined by the Operating Committee, each Party shall be required to participate in such operation and such operation shall be treated as if it was conducted under the Drilling Program.

(f) Notwithstanding anything to the contrary in this Agreement or the Drilling Program, Gasco is expressly authorized to, and shall, make expenditures and incur liabilities when it reasonably determines that such expenditures or incurrences are necessary or advisable to deal with emergencies, including well blowouts, fires, oil spills or any other event which may endanger property, lives or the environment. Gasco shall immediately, by telephone and email report to Wapiti the occurrence and nature of any such emergency that arises, the measures it intends to take or has taken in respect of such emergency and the estimated related expenditures.

(g) Gasco shall use its reasonable best efforts during the Drilling Term to conduct all operations at the time prescribed in the Drilling Program.

costs and expenses for such operation, and all revenues derived from such operation, shall be subject to Section 5.2, and (D) any drilling operation involving the drilling of a new wellbore (as opposed to reentering the wellbore for a Program Well), whether such drilling operation is located within the Spacing Units for a Program Well or not, and any sidetracking, deepening, recompleting reworking, plugging back of xxxxx or intervals therein or other operation involving a new wellbore, shall be considered outside of the Drilling Program, any well related to an operation for a new wellbore shall not be considered a Program Well and the costs and expenses for such operation, and all revenues derived from an operation for a new wellbore, shall be allocated in accordance with Section 5.3.

(b) Early Termination of Drilling Program.

(i) Except with respect to any Ongoing Operations, as soon as Wapiti has expended $10 million on Drilling and Completion Costs relating to Program Xxxxx (the “Trigger Event”), Gasco shall cease conducting all operations contemplated by the Drilling Program pending a decision by the Operating Committee to terminate the Drilling Program in accordance with this Section 4.3(b).

(ii) Within 15 days following the Trigger Event, the Operating Committee will hold a meeting to review the results of the Drilling Program prior to the Trigger Event and will hold a vote to determine whether, based on the overall economic performance of the Drilling Program prior to the Trigger Event, to terminate the Drilling Program in accordance with this Section 4.3(b).

(ii) Notwithstanding anything in this Agreement or the Drilling Program to the contrary, no Party may propose to drill any well on or including the Wilkin Ridge Interests until the Wilkin Ridge Test Well has been drilled and tested or propose to drill any well on or including the Gate Canyon Interests until the Gate Canyon Test Well has been drilled and tested.

(iii) The Parties hereby agree that if the EIS has not been obtained by the time that $23.6 million of the $30 million of the Wapiti Commitment has been expended on Drilling and Completion Costs contemplated by the Drilling Program, Gasco may elect to suspend the Drilling Program for up to six (6) months, including suspending Wapiti’s obligations with respect to expending the remainder of the Wapiti Commitment on Drilling and Completion Costs contemplated by the Drilling Program. Beginning on the date of such suspension and ending on the earlier to occur of (x) the Spudding of either the Gate Canyon Test Well or the Wilkin Ridge Test Well and (y) the six (6) month anniversary of such suspension (the “Extension Period”), unless otherwise extended by the Operating Committee, Gasco shall have no obligation to conduct any operations contemplated by the Drilling Program and all xxxxx that are Spudded during such Extension Period will not be Program Xxxxx. If the EIS is obtained during the Extension Period, then Gasco will, as promptly as is reasonably practical thereafter, begin drilling the Gate Canyon Test Well and the Wilkin Ridge Test Well (and the Spudding of either well will xxxx the end of the Extension Period and the resumption of the Drilling Program). Upon the end of the Extension Period, the Drilling Program, including Wapiti’s obligation to pay Drilling and Completion Costs in accordance with Section 5.2, will resume. In no event will Wapiti be required to forfeit any acreage in the Gate Canyon Interests or the Xxxxxxx Ridge Interests, on account of the Gate Canyon Test Well and the Wilkin Ridge Test Xxxxx specifically not being drilled in accordance with the terms of the Drilling Program. During the Extension Period, the Parties obligations with respect to any xxxxx that are classified as Program Xxxxx as of the beginning of such Extension Period shall not be modified as a result of this Section 4.3(c)(iii), except that all costs attributable to such Program Xxxxx that are otherwise allocable between the Parties in accordance with Section 5.2(a)(i) shall be allocated between the Parties in accordance with Section 5.2(a)(ii) and neither the Gasco Commitment or the Wapiti Commitment shall be reduced by any Drilling and Completion Costs expended by the Parties during the Extension Period.

(d) Environmental Impact Study.

(i) Except with respect to any Ongoing Operations, in the event that the Parties have not received final approval by the appropriate Governmental Authorities of an environmental impact study with respect to the Wilkin Ridge Interests and the Gate Canyon Interests (the “EIS”) by December 31, 2012 (the “EIS Outside Date”) and Gasco has not received a sufficient number of drilling permits by the EIS Outside Date to allow Gasco to conduct the specific operations contemplated by the Drilling Program that are reasonably sufficient to utilize the Parties’ $37.5 million Drilling and Completion Costs commitment to the Drilling Program, then Wapiti may elect to terminate the Drilling Program by providing written notice of the same to Gasco within 15 days following the EIS Outside Date; provided that Wapiti shall not be permitted to exercise its right to terminate the Drilling Program under this Section 4.3(d) if Wapiti is in Default pursuant to Article IX or any Associated Agreement at the time it exercises such right.

(ii) If Wapiti exercises its right to terminate the Drilling Program in accordance with Section 4.3(d)(i), then within 90 days following the date on which Wapiti exercises such right (but effective as of the EIS Outside Date), Wapiti and its Affiliates shall assign to Gasco, in the same form of assignment as it received such interests, and free and clear of, all claims by, through or under Wapiti or its Affiliates, but not otherwise, an undivided interest in all of the Wapiti Non-Producing Interests in an amount equal to the percentage determined by dividing (x) $30 million minus the amount of all Drilling and Completion Costs that have actually been paid by Wapiti in respect of the Program Xxxxx and the Drilling Program as of the date of such reassignment by (y) $30 million; provided that such reassignment shall specifically exclude Wapiti’s interest in any Non-Producing Interests and related assets to the extent such Non-Producing Interests are located within the Spacing Unit for any previously Spudded Program Well. Upon consummation of such reassignment, Wapiti and its Affiliates shall have satisfied their commitment obligation to the Drilling Program and the Drilling Program shall be terminated.

(iii) From and after the Closing Date, each Party shall take such further actions and execute such further documents as may be necessary or reasonably requested by Gasco in order to obtain final approval by the appropriate Governmental Authorities of the EIS by the EIS Outside Date. Further, each of Gasco and Wapiti shall be responsible for one-half of all reasonable fees, costs and expenses paid to third parties incurred by Gasco (and excluding any internal general or administrative costs, including but not limited to, salaries, bonuses and benefits of Gasco employees) with respect to the Subject Interests in pursuing the EIS from and after the Closing Date and Gasco shall be entitled to invoice Wapiti for such fees, costs and expenses, and Wapiti shall pay such fees, costs and expenses, in accordance with Section 5.4.

4.4 Operations Outside of the Drilling Program; Development Program. Subject to Section 4.2(f),

(a) Prior to the end of the Drilling Term. Prior to the end of the Drilling Term, unless otherwise approved by the Operating Committee, no Party or its Affiliates shall propose any operations covering the Subject Interests under any Applicable Operating Agreement that is not included in the Drilling Program.

(b) After the end of the Drilling Term.

(i) From and after the end of the Drilling Term, prior to any Party or its Affiliates proposing any drilling, completion, sidetracking, deepening, recompletion, reworking and plugging back of xxxxx operations with respect to the Subject Interests under an Applicable Operating Agreement (a “Potential Operation”), a Party must first submit such Potential Operation to the Operating Committee for approval. When voting on or consenting to a Potential Operation, the members of the Operating Committee may either (i) vote in favor of the Potential Operation, (ii) vote against the Potential Operation or (iii) abstain with respect to the Potential Operation. If any member of the Operating Committee fails to vote with respect to a Potential Operation or fails to respond to consent request within the time period specified in Section 4.1(f) with respect to a Potential Operation, then such member of the Operating Committee shall be deemed to have voted against the Potential Operation. If all members of the Operating Committee vote in favor of, or consent to, such Potential Operation, then the Party

presenting such Potential Operation may propose such Potential Operation under the terms of the Applicable Operating Agreement. If any member of the Operating Committee votes against, abstains from, or fails to consent to, such Potential Operation, then the Party submitting must wait at least 90 days before proposing such Potential Operation under the terms of the Applicable Operating Agreement. If any Potential Operation is not actually commenced within 180 days of such proposals, then such Potential Operation shall again become subject to the terms of this Section 4.4(b). Notwithstanding the foregoing, (X) Section 4.2(f) shall govern expenditures regarding emergencies, including well blowouts, fires, oil spills or any other event which may endanger property, lives or the environment, and (Y) the terms of the Gasco Operating Agreement or Wapiti Operating Agreement, as applicable, shall prevail over the terms of this Section 4.4(b)(i) in the event of an operation to maintain a lease. Notwithstanding anything in this Section 4.4(b) to the contrary, regardless of whether a Party’s representative to the Operating Committee votes in favor of, against or abstains with respect to a Potential Operation, each Party shall have the right to make a nonconsent election with respect to any Potential Operation to the extent permitted under the terms of the Applicable Operating Agreement.

(ii) In addition to the requirements of Section 4.4(b)(i), commencing in the year in which the Drilling Term ends, on or before October 31 of such calendar year and of each subsequent calendar year, each Party serving as operator under one of the Joint Operating Agreements (a “Party Operator”) shall, with respect to its portion of the Contract Area, prepare and submit to the Operating Committee an annual plan and budget (as amended or revised, the “Annual Plans and Budgets”) for operations that such Party Operator reasonably anticipates on conducting during such upcoming calendar year (the “relevant calendar year”). In addition, each Party will provide a summary of its drilling and development operations and results of such operations for the current year to the extent relating to the Subject Interests. Following distribution of such Annual Plans and Budgets, the Operating Committee and the Party Operators shall meet to discuss such Annual Plans and Budgets and any recommendations that any members of the Operating Committee may make with respect thereto, and each Party will have the right to have a technical meeting with the other Party to review the G&G Information generated during the drilling operations for the current year. If a Party Operator determines to make any revisions to its Annual Plan and Budget based upon such meeting, then promptly following such meeting (and in any event prior to January 1 of the relevant calendar year), such Party Operator shall, with respect to its portion of the Contract Area, prepare and submit to the Operating Committee a revised Annual Plan and Budget based on such revisions. Any such Annual Plan and Budget shall be for informational purposes only and shall not bind any Party or Party Operator to either propose or participate in the operations contemplated thereby; provided however that, during each relevant calendar year, each Party Operator shall (1) use its reasonable best efforts to amend its Annual Plan and Budget so that the Annual Plan and Budget for such relevant calendar year continually reflects such Party Operator’s intentions with respect to conducting operations in the applicable portion of the Contract Area during such relevant calendar year, (2) provide any such amendments to the Operating Committee promptly after finalizing such amendments, and (3) at the request of any member of the Operating Committee, meet with the Operating Committee at least once per calendar quarter to discuss any such amendments to such Annual Plan and Budget, such meetings to include any G&G Information that was used to determine to make such revisions. Each Party Operator shall consider in good faith any recommendations made in respect of its Annual Plan and Budget by any member of the Operating Committee. Notwithstanding the foregoing, until the termination of the Contract

Operating Agreement, Gasco shall be deemed to be the Party Operator for the Wapiti Contract Area.

(c) Third Party Proposed Operations. Notwithstanding anything in this Section 4.4 to the contrary, but subject to Section 4.2(d), if a third party proposes an operation pursuant to an Applicable Operating Agreement, then unless otherwise determined by the Operating Committee, each Party shall have the right to elect to participate or not to participate in such operation. For clarity, if the third party proposes the operation prior to the end of the Drilling Term and the operation is not contemplated by the Drilling Program, then unless otherwise determined by the Operating Committee, the operation will not be part of the Drilling Program.

4.5 AFEs. Prior to Gasco (a) Spudding any Program Well, or (b) making any expenditure under the Drilling Program that is estimated to cost in excess of $50,000, Gasco shall submit an authority for expenditure to the Parties covering such well or expenditure for information purposes only.

ARTICLE VII
AREA OF MUTUAL INTEREST

7.1 Creation of Area of Mutual Interest. The Parties agree that the area outlined on Exhibit “I” hereto shall be the Contract Area, which includes the Subject Interests and a perimeter around the Subject Interests and shall be the area of mutual interest subject to the terms hereof.

7.2 Acquisition of Option Interests.

(a) If, after the date hereof, a Party or any of its Affiliates, directly or indirectly (including by merger, acquisition of equity or otherwise), acquires or seeks to acquire any additional Leases and related assets within the Contract Area (such Party, the “Acquiring Party”), then the Acquiring Party (i) will in the case of any acquisition that has already taken place and (ii) may in the case of any proposed acquisition, promptly provide written notice (the “Acquisition Notice”) to the other Party (the “Non-Acquiring Party”) of such acquisition or proposed acquisition, as applicable, including the material terms and conditions (excluding any terms dealing solely with assets not within the Contract Area) of such acquisition and a description of the Leases and related assets that are being or have been acquired (the “Option Interests”); provided, however, that the Excluded Assets (as defined in the Purchase Agreement) shall not be treated as Option Interests or subject to this Section 7.2. Within 30 days after such Acquisition Notice is delivered to the Non-Acquiring Party, the Non-Acquiring Party will have the option to acquire all, but not less than all, of its Participating Interest share of such Option Interests on the same terms and conditions on which the Acquiring Party acquired or will acquire the Option Interests by providing written notice of such election to the Acquiring Party. If the Non-Acquiring Party fails to exercise its option within such 30-day period, such Non-Acquiring Party shall be deemed to have made an election not to participate.

(b) If the Non-Acquiring Party elects to participate in accordance with Section 7.2(a), such Non-Acquiring Party shall purchase its share of the Option Interests from the Acquiring Party within 30 days of its election in the case of any acquisition that has already

taken place, or in the case of a proposed acquisition, at the closing of such acquisition (or as promptly as practicable thereafter as the Acquiring Person may reasonably determine) (such date, the “Payment Date”). At the closing of such purchase (an “AMI Purchase Date”), (i) the Non-Acquiring Party will be required to (A) except for obligations assumed pursuant to clause (B) below, pay to the Acquiring Party (or to such other Person as the Acquiring Party may designate) its share of the Acquisition Costs in proportion to the interest in the Option Interests it is acquiring in cash, together with interest thereon at the Agreed Rate from the date on which the Acquiring Party acquired the Option Interests (if earlier than the Payment Date) to the Payment Date and (B) if the Option Interest is acquired pursuant to a farmout agreement or similar agreement requiring the drilling of a well or the performance of other similar obligations assume its share of all obligations required to be performed by the Acquiring Party or its Affiliates to earn such Option Interest and (ii) the Acquiring Party shall deliver to such Non-Acquiring Party its interest in the Option Interests on the same terms and conditions as such Acquiring Party is or has acquired its interest in the Option Interests (with such changes as may be necessitated by the differences in the parties, the transfer of only the Option Interests and, if applicable, the payment of the Fair Market Value in lieu of other consideration or the apportionment of rights from a Package Sale); provided that, except for a special warranty of title covering the Acquiring Party’s period of ownership, the Acquiring Party shall in no event have any liability to the Non-Acquiring Party for representations, warranties or indemnities with respect to the Option Interest in excess of the Non-Acquiring Party’s Participating Interest shares of amounts that the Acquiring Party actually recovers from the Person from whom it acquired the Option Interest. The Non-Acquiring Party will be responsible for and will pay the costs of recording the assignment of its interest in the Option Interests in the real property records of the appropriate county or township as applicable.

(c) If the Non-Acquiring Party elects not to participate in accordance with Section 7.2(a), the Acquiring Party will retain 100% of the Option Interests and such Option Interests will be excluded from the Contract Area and will not be governed by the terms of this Agreement or any Applicable Operating Agreement.

(d) If an Acquiring Party acquires or seeks to acquire any Lease and related assets that lie partially within and partially outside of the Contract Area, then only the portion of such Lease and related assets that lies within the Contract Area shall be deemed to be an Option Interest and any portion of the Lease and related assets that lies outside of the Contract Area shall not be subject to this Article VII. Unless there is a clear and convincing reason to differentiate between the acreage within the area of mutual interest and the acreage outside the area of mutual interest, the acquisition costs shall be allocated on a per acre basis.

7.3 Acquisition Activities. Prior to any Party or its Affiliates acquiring any Lease and/or related assets in the Contract Area, such Party shall use its commercially reasonable efforts to coordinate its acquisition activities with the other Party, including using its commercially reasonably efforts to provide the other Party with reasonable advance notice of any potential acquisition and allowing such other Party the opportunity to participate in such acquisition.

ARTICLE VIII
TAXES

8.1 Tax Partnership. The Parties intend and expect that the transactions contemplated by this Agreement and the Associated Agreements, taken together, will be treated, for purposes of federal income taxation and for purposes of certain state income tax laws that incorporate or follow federal income tax principles (“Tax Purposes”), as resulting in the creation of a partnership (the “Tax Partnership”) in which Gasco and Wapiti are treated as partners. Accordingly, for Tax Purposes, (a) Gasco will be treated as selling the Wapiti Producing Interests, the Wapiti Non-Producing Interests and a joint ownership interest in the G&G Information that is not subject to the License Agreement in exchange for the Final Purchase Price, (b) Gasco will be treated as contributing to the Tax Partnership on the Closing Date all of its interests in the Gasco Producing Interests, the Gasco Non-Producing Interests and the G&G Information that is not subject to the License Agreement and providing its undertaking to fund, when due, the costs and expenses allocable to it under this Agreement and the Associated Agreements in exchange for an interest in the Tax Partnership; (c) Wapiti will be treated as contributing to the Tax Partnership on the Closing Date all of its interests in the Wapiti Producing Interests, the Wapiti Non-Producing Interests and the G&G Information that is not subject to the License Agreement and providing its undertaking to fund, when due, the costs and expenses allocable to it under this Agreement and the Associated Agreements in exchange for an interest in the Tax Partnership; and (d) the Tax Partnership will be treated from and after the Closing as (i) holding 100% of the Parties’ interests in the Subject Interests, (ii) engaging in all activities of the Parties with respect to the Subject Interests and (iii) realizing all items of income or gain and incurring all items of cost or expense attributable to the ownership, operation or disposition of the Subject Interests (and any other assets acquired or developed by the Parties jointly pursuant to the Development Agreement), notwithstanding that such items are realized, paid or incurred by the Parties individually. The governing terms and conditions of the Tax Partnership are set forth in the form thereof to be executed on the Closing Date, attached as Exhibit G (the “Tax Partnership Agreement”), and shall be consistent with this Section 8.1. Any Transfer (other than a Transfer of an Immaterial Interest) by any Party that is otherwise permitted pursuant to Section 6.1 shall not be effective unless the permitted transferee agrees in writing that the Joint Development Interest it is acquiring in the Transfer will be subject to the Tax Partnership Agreement.

8.2 Tax Information. Gasco shall provide each Party, in a timely manner and at each Party’s sole expense, with information with respect to operations covering the Subject Interests conducted by Gasco as such Party may reasonably request for preparation of its tax returns or responding to any audit or tax proceeding with respect to Asset Taxes.

8.3 Responsibility for Taxes. Each Party shall be responsible for reporting and discharging its own tax measured by the income of the Party and the satisfaction of such Party’s share of all contractual obligations under this Agreement and the Associated Agreements. Each Party shall protect, defend, and indemnify each other Party from and against any and all losses, costs, and liabilities arising from the indemnifying Party’s failure or refusal to report and discharge such taxes or satisfy such obligations.

ARTICLE IX
DEFAULTS

9.1 Defaults.

(a) In the event that any Party fails to pay any of its share of costs and expenses (after giving effect to Section 5.2) under this Agreement or any Associated Agreement (a “Default”), in each case, on or before the Initial Default Date, (such Party, a “Defaulting Party”), then (i) the other Party (the “Non-Defaulting Party”) shall provide written notice of such default (a “Default Notice”) to such Defaulting Party within 10 days after the Initial Default Date (provided any failure by the Non-Defaulting Party to give such notice within such time period shall not affect any rights or remedies of the Non-Defaulting Party in this Agreement or any Associated Agreement, but shall be a covenant for the benefit of the Defaulting Party solely for the purpose of allowing the Defaulting Party to assert a claim in the event the Defaulting Party incurs damages caused by the Non-Defaulting Party’s failure to give any such notice within such period) and (ii) in addition to (A) the remedies available to any Non-Defaulting Party under any Associated Agreements, (B) those remedies that occur automatically pursuant to Section 9.2, and (C) any and all other rights and remedies under this Agreement or at Law or in equity, the Non-Defaulting Party shall be entitled to exercise, in its sole discretion, any one or more of the remedies set forth in Section 9.3 during the period of time beginning on the Initial Default Date until the date upon which the Total Amount in Default has been fully cured (the “Default Period”). In addition, the Parties agree that the failure of Wapiti to deliver the Letter of Credit to Gasco by the deadline specified in Section 5.1(c) shall constitute a Default under this Agreement.

(b) All amounts in default and not paid when due under this Agreement shall bear interest at the Agreed Rate from the due date to the date of payment.

9.2 Certain Automatic Remedies for a Default.

(a) Generally. Unless the Non-Defaulting Party elects in writing to waive or extend the time period for any or all of the following, then, for a period (1) beginning on the earlier of (x) the 10th day after the date on which the Defaulting Party receives the Default Notice and (y) 20 days after the Initial Default Date and (2) ending upon the expiration of the Default Period, the Defaulting Party shall automatically not be entitled to:

(i) make any proposal under this Agreement or any Applicable Operating Agreement or elect to participate in any operation under this Agreement or any Applicable Operating Agreement;

(ii) vote on any matter with respect to which approval is required under the express terms of this Agreement or any Associated Agreement (excluding any amendment or waiver of the terms of any such agreement);

(iii) call any Operating Committee meeting or be entitled to vote there at, with the quorum and voting requirements adjusted accordingly;

(iv) send its representatives or advisors to any meeting of the Operating Committee;

(v) access any data or information relating to any operation conducted under this Agreement or any Associated Agreement (except to the extent that the Defaulting Party is the operator of any interest in question, in which case such operator shall be entitled to such data and information as may be necessary to perform its responsibilities under the terms of the Applicable Operating Agreements and the Contract Operating Agreement);

(vi) Transfer all or any part of its Joint Development Interest or any other Subject Interest undergo a Change in Control or encumber all or any part of its Joint Development Interest or any other Subject Interests, except in a case of a Transfer of a Joint Development Interest to, or a Change in Control with, a Person or encumbrance in favor of a Person who simultaneously with such Transfer, Change in Control or encumbrance satisfies in full the Total Amount in Default;

(vii) offer to acquire any Offered Interest pursuant to Section 6.4; or

(viii) elect to acquire any Option Interests pursuant to Section 7.2.

(b) Certain Remedies. If Wapiti is a Defaulting Party with respect to the Wapiti Commitment (a “D&C Payment Default”), then unless Gasco elects in writing to waive or extend the time period for the following, as of the earlier to occur of (x) the 50th day after the date on which Wapiti, as the Defaulting Party, receives the Default Notice for such D&C Payment Default and (y) 60 days after the Initial Default Date for such D&C Payment Default (the “D&C Acceleration Trigger”), Wapiti shall be required to pay the Outstanding Wapiti Commitment Balance as a lump sum payment (such payment, the “D&C Balance Payment”). Promptly following the D&C Acceleration Trigger, but in any event within five Business Days following the date of such D&C Acceleration Trigger, Wapiti shall pay to Gasco the D&C Balance Payment by wire transfer of immediately available funds to an account specified by Gasco in writing to Wapiti. Notwithstanding anything in this Agreement to the contrary, upon Gasco’s receipt of the D&C Balance Payment, Wapiti will be deemed to have satisfied its obligation to pay Drilling and Completion Costs under the Drilling Program in the amount of the D&C Balance Payment and Gasco thereafter shall be responsible for paying such obligation as and when it becomes due.

9.3 Certain Other Remedies for a Default.

(a) Right to Entitlements. From and after the 30th day after the Initial Default Date, a Defaulting Party shall have no right to receive its Entitlement from the Subject Interests and the Non-Defaulting Party shall have the right to collect such Entitlement; provided that the proceeds from all such Entitlements shall be used to pay the Total Amount in Default and shall be deemed, first, to apply to the portion of the Total Amount in Default that relates to any portion to any unpaid Drilling and Completion Costs and, second, and only to the extent that all defaults have been cured with respect to the unpaid Drilling and Completion Costs, proportionately to the remainder of the Total Amount in Default.

(b) Specific Performance. Any Non-Defaulting Party shall be entitled to seek specific performance of any of the Defaulting Party’s obligations under this Agreement or any Associated Agreement.

(i) In addition to the other remedies available hereunder to Wapiti, if Gasco or any of its Affiliates is a Defaulting Party, from and after the 50th day after the Initial Default Date, then, and so long as Wapiti or any of its Affiliates is not in Default and Gasco or its applicable Affiliate is not disputing the applicable Default in good faith, Wapiti may deliver to Gasco a notice that it is electing to remove Gasco as contract operator under the Contract Operating Agreement and as operator under any Applicable Operating Agreement (and Gasco shall take all action as is necessary to resign as operator under such Applicable Operating Agreements), effective as of the date of such notice (or such later date as Wapiti shall specify in such notice), and Gasco shall use its commercially reasonable efforts to elect Wapiti or its designee as operator under such Applicable Operating Agreements. To the extent Gasco is given any special rights or is subject to as special obligations with respect to implementing and administering the Drilling Program under the terms of this Agreement and Gasco is removed as contract operator and operator pursuant to the terms of this Section 9.3(c), then Wapiti shall be given such special rights and assume such special obligations for the purpose of implementing and administering the Drilling Program in accordance with the terms of this Agreement.

(ii) In addition to the other remedies available hereunder to Gasco, if Wapiti or any of its Affiliates is a Defaulting Party, from and after the 50th day after the Initial Default Date, then, and so long as Gasco or any of its Affiliates is not in Default and Wapiti or its applicable Affiliate is not disputing the applicable Default in good faith, Gasco may deliver to Wapiti a notice that it is electing to remove Wapiti as operator under any Applicable Operating Agreement (and Wapiti shall take all action as is necessary to resign as operator under such Applicable Operating Agreements), effective as of the date of such notice (or such later date as Gasco shall specify in such notice), and Wapiti shall use its commercially reasonable efforts to elect Gasco or its designee as operator under such Applicable Operating Agreements.

(d) Letter of Credit. In addition to the other remedies available hereunder to Gasco, Gasco may draw on the Letter of Credit in an amount equal to the lesser of the full amount of the Letter of Credit and the Outstanding Wapiti Commitment Balance at the time of such drawdown if prior to the end of the Drilling Term either (x) there is a D&C Payment Default or (y) the Letter of Credit is set to terminate in accordance with its terms and Wapiti has not delivered to Gasco a new Letter of Credit on the same terms and conditions as those contained in the original Letter of Credit in an amount equal to the lesser of $10 million and the Outstanding Wapiti Commitment Balance.

(e) Mortgage. In addition to the other remedies available hereunder to Gasco, from and after the 30th day after the Initial Default Date, Gasco may exercise its rights under the Mortgage to cure the Total Amount in Default with respect to any D&C Payment Default by Wapiti.

(f) Offset. Any Non-Defaulting Party and its Affiliates shall be permitted to offset any amounts owed to it by a Defaulting Party or its Affiliates.

(g) Limited Reassignment Remedy. In addition to the other remedies available hereunder to Gasco, in the event Wapiti has not delivered the Letter of Credit to Gasco by the deadline specified in Section 5.1(c), Gasco may require Wapiti, for no consideration, to reassign, effective as of the date of the deadline specified in Section 5.1(c), using substantially the same form of Assignment and Xxxx of Sale pursuant to which the Wapiti Non-Producing Interests were assigned by Gasco to Wapiti at Closing, and with special warranty of title for claims arising by, through or under Wapiti and its Affiliates but not otherwise, to Gasco, all of Wapiti’s and its Affiliates’ right, title and interest in and to the Wapiti Non-Producing Interests, but excluding any interest in any Program Well that is part of the Wapiti Non-Producing Interests on which a well has been drilled as of such date.

9.4 Pledged Non-Producing Interests.

(a) In order to secure the Wapiti Commitment, Wapiti shall execute, acknowledge and deliver to Gasco on the Closing Date the Mortgage which will grant to Gasco (i) a first priority lien upon and security interest in the Wapiti Non-Producing Interests and (ii) a first priority lien on and security interest and/or purchase money security interest in any interest it now owns or hereafter acquires in the personal property and fixtures on or used or obtained for use in connection with such Wapiti Non-Producing Interests (the “Pledged Non-Producing Interests”).

(b) Gasco is authorized to file the Mortgage as a lien, mortgage and/or deed of trust (and/or notice thereof) in the applicable real estate records and as a financing statement with the proper officer under the Uniform Commercial Code in the states in which the Pledged Non-Producing Interests are situated and such other states as Gasco shall deem appropriate to perfect the security interest granted under the Mortgage. In furtherance of the foregoing, Wapiti, by its execution of this Agreement, hereby authorizes Gasco, and grants to Gasco a limited power of attorney, to execute, file and/or record on behalf of Wapiti any documents or instruments necessary, desirable or appropriate to grant and perfect the lien described in Section 9.4(a) and to correct any ministerial errors that Gasco may find from time to time in the Mortgage, including amendments to the Mortgage or additional mortgages or deeds of trust in substantially the form of the Mortgage, as applicable (collectively, the “Mortgage Amendments”) which power is coupled with an interest and irrevocable so long as this Agreement is in effect.

(c) All Persons acquiring an interest in the Pledged Non-Producing Interests, including Wapiti, whether by assignment, merger, mortgage, operation of Law, or otherwise, shall be deemed to have taken subject to the lien and security interest granted pursuant to the Mortgage and as to all obligations attributable to such interest hereunder, whether or not such obligations arise before or after such interest is acquired.

(d) Gasco hereby covenants and agrees that, upon request the written request of Wapiti at each June 30 and December 31 during the Drilling Term, beginning December 31, 2012, it will enter into, execute and deliver a recordable partial release of the Mortgage (in each case, a “Partial Release”), releasing from the Mortgage a percentage of the undivided interest in

the Pledged Non-Producing Interests (in each case, a “Partial Release Percentage”) and a final release upon the Outstanding Wapiti Commitment Balance equaling zero, all in accordance with the terms hereof. Each Partial Release Percentage shall be the fraction, expressed as a percentage, equal to (i) $30 million minus the amount that Wapiti has actually expended on Drilling and Completion Costs in accordance with Section 5.2(a)(i) since either (x) in the case of the first Partial Release, the Closing Date and (y) in the case of any subsequent Partial Release, the date used for the calculation of the Partial Release Percentage of the immediately preceding Partial Release, divided by (ii) $30 million. Gasco shall also take any further action as may be necessary to effectuate these Partial Releases and the final release of any remaining lien upon or security interest in the Pledged Non-Producing Interests granted under this Section 9.4 in any Pledged Non-Producing Interests upon the Outstanding Wapiti Commitment Balance equaling zero.

9.5 Cumulative and Additional Remedies. The rights and remedies granted to Non-Defaulting Party in this Article IX shall be cumulative, not exclusive, and shall be in addition to any other rights and remedies that may be available to the Non-Defaulting Party, at Law, in equity or otherwise. Each right and remedy available to a Non-Defaulting Party may be exercised from time to time and so often and in such order as may be considered expedient by a Non-Defaulting Party in its sole discretion. The Non-Defaulting Party shall be entitled to recover from the Defaulting Party all reasonable attorney’s fees and other reasonable costs and expenses sustained in connection with the enforcement of its rights and remedies against the Defaulting Party under this Agreement.

The Party holding or controlling such data and information, as the case may be, will use its commercially reasonable efforts to obtain the consent of the applicable party to disclose any such data to the other Party (to the extent applicable to such Party’s interest in the Subject Interests at such time) if such disclosure is otherwise prohibited without such consent. Other than with respect to amounts required to be paid to obtain a separate license for, or any necessary consent to share, any information that was held by Gasco prior to the Closing Date, the costs of acquiring, transferring or sharing any such data and information (including any fee amounts required to be paid to obtain any necessary consents) for any Subject Interests will be borne and paid by the Parties in relation to their Participating Interests.

EACH PARTY EXPRESSLY AGREES THAT ANY RELIANCE UPON OR CONCLUSIONS DRAWN FROM ANY MATERIALS, DOCUMENTS AND OTHER INFORMATION PROVIDED BY ANOTHER PARTY SHALL BE AT ITS OWN RISK TO THE MAXIMUM EXTENT PERMITTED BY LAW AND SHALL NOT GIVE RISE TO ANY LIABILITY OF OR AGAINST THE PROVIDING PARTY. EACH PARTY HEREBY WAIVES AND RELEASES ANY CLAIMS ARISING UNDER THIS AGREEMENT, COMMON LAW OR ANY STATUTE ARISING OUT OF ANY MATERIALS, DOCUMENTS OR INFORMATION PROVIDED BY THE OTHER PARTY TO SUCH PARTY.
