or the Secured Party may originate the Initial Instruction or any Disposition Instruction. 
 5. The Bank’s Recourse to

 4 

	 GENERAL TERMS FOR THE DEPOSIT ACCOUNT

access or otherwise, a copy of each periodic account statement relating to the Deposit Account ordinarily furnished by the Bank to the Debtor. The Bank’s liability for failing to provide the account statement will not exceed the Bank’s

the Secured Party’s request.

Bank terminates this Agreement pursuant to clause (B) or (C) of Section 9(a)(ii), the Bank will remit any funds in the Deposit Account on the date of termination at the direction of the Secured Party only if the direction is received

 (c) Except as provided in Section 9(b) and in any event if the Secured Party has communicated to the Bank that the
Secured Party does not wish to receive or direct the disposition of the funds, the Secured Party will not receive from the Bank any remittance of funds from the Deposit Account upon termination of this Agreement by the Bank.

 (a) All communications under this Agreement must be
in writing and must be delivered by hand or overnight courier service, mailed by certified or registered mail, or sent by facsimile to the party addressee. If the Specific Terms permit a writing to include an electronic record, a
communication, other than the Initial Instruction, may be sent by email. 
 (b) For a communication under this Agreement to be

Agreement, in each case subject to any change in address provided in Section 10(c). Receipt of the Initial Instruction does not occur until it is received by the person or persons or department specified on the “attention” line on the
Exhibit. If

 
more than one person is specified, receipt occurs when the Initial Instruction is received by one of the persons. 
 (c) The Bank may communicate to the Secured Party changes in the address for the Initial Instruction, and any party may communicate to the other parties changes in its address for communications
under this Agreement. 
 11. Successors and Transferees. 

(a) This Agreement will inure to the benefit of, and be binding upon, the parties and their respective successors and other transferees
permitted under this Section. Except as provided in this Section, a voluntary transfer of a party’s rights or duties under this Agreement without the written consent of the other parties will be void. 

(b) The Bank may transfer its rights and duties under this Agreement to a transferee to which, by contract or operation of law, the Bank
transfers substantially all of its rights and duties under the Deposit-related Agreements. 
 (c) The Secured Party may transfer
its rights and duties under this Agreement to (i) a transferee to which, by contract or operation of law, the Secured Party transfers substantially all of its rights and duties under the financing or other arrangements between the Secured Party
and the Debtor for which the Deposit Account acts as collateral security or (ii) if the Secured Party is acting as a trustee, indenture trustee, agent, collateral agent, or other representative in whose favor a security interest is created or
provided for, a transferee that is a successor trustee, indenture trustee, agent, collateral agent, or other representative. 

(d) No transfer under this Section will be binding upon a non-transferring party until the transferring party or the transferee notifies
the non-transferring parties of the transfer in a writing signed by the transferee that identifies the transferee, gives the transferee’s address for communications under this Agreement, and states that the transferee is a successor of the
transferor or other transferee permitted under this Section and is entitled to the benefit of the

 

  
 6 

	 GENERAL TERMS FOR THE DEPOSIT ACCOUNT
CONTROL AGREEMENT 
	 6 

 

 

 
transferring parry’s rights and has assumed all of the transferring party’s duties under this Agreement. 
 (e) A non-transferring party need not request proof of any transfer or that the transferee is a successor of the transferor or other transferee permitted by this Section. If requested by a
non-transferring party, however, the transferring party or the transferee will provide reasonable proof thereof. If the Bank or the Secured Party, as a non-transferring party, requests such proof, then the effectiveness of the notification of
transfer as to the non-transferring party will be suspended until the proof is provided. 
 (f) When a transfer becomes binding
on the non-transferring parties, the transferring party will not be entitled to exercise any rights, and will be relieved of its obligations, accruing under this Agreement from and after that time. Those rights may be exercised and those obligations
will be incurred by the transferee. 
 (g) The provisions of subsections (d) and (e) requiring notification for a
transfer to be binding on the non-transferring parties and suspending the effectiveness of the notification of transfer until reasonable proof of the transfer has been provided do not apply to the Bank as the transferring party if the transfer is by
operation of law and by operation of the law (i) the transferee succeeds to all or substantially all of the rights and becomes generally bound by all of the duties of the Bank, including the Bank’s duties under this Agreement, and
(ii) the Bank ceases to exist. 
 12. Entire Agreement; Relation to Other Agreements. 

(a) This Agreement constitutes the entire agreement of the parties, and supersedes all previous and contemporaneous negotiations,
understandings and agreements, with respect to its subject matter, all of which have become merged and finally integrated into this Agreement. 
 (b) If a term in the Specific Terms conflicts with a term of this Agreement not in the Specific Terms, the term in the Specific Terms controls. 

(c) If this Agreement conflicts with any of the Deposit-related Agreements, this Agreement will control. However, this Agreement will not
(i) derogate from any Claim or defense that

 
the Bank may have against the Debtor under any of the Deposit-related Agreements or (ii) create any third party beneficiary rights under any of the Deposit-related Agreements in favor of the
Secured Party. 
 (d) This Agreement does not amend or otherwise modify any of the agreements between the Debtor and the Secured
Party or provide any rights for the Debtor to originate a Disposition Instruction in contravention of any agreement between the Debtor and the Secured Party. 
 13. Governing Law, Depositary Bank’s Jurisdiction and Waiver of Jury Trial. 
 (a) Except as otherwise required by Article 9 of the UCC, this Agreement will be governed by the law of that jurisdiction set forth in the Specific Terms without giving effect to any choice of law
rule that would require the application of the law of another jurisdiction. 
 (b) If the Specific Terms are completed
expressly to designate the Bank’s jurisdiction for purposes of part 3 of Article 9 of the UCC, then the Deposit-related Agreements are amended to provide that for those purposes that jurisdiction is the Bank’s jurisdiction so designated.

 (c) To the extent permitted by applicable law, each party waives all rights to trial by jury in any action, claim or

 12 

 Section 5.02 No Warranty or Representation. 

Seller shall convey Seller’s interests in and to the Assets to Buyer subject to the Permitted Encumbrances and
without any warranty of title, express or implied, except Seller shall warrant and forever defend all and singular the Assets conveyed unto Buyer, its successors and assigns against every person whosoever lawfully claiming the Assets or any part
thereof, by, through or under Seller, but not otherwise. Other than the representations made in Section 4.01, Seller makes no warranty or representation, express or implied, with respect to the accuracy or completeness of the information,
records and data now, heretofore or hereafter made available to Buyer in connection with this Agreement (including, without limitation, any description of the Assets, pricing assumptions, potential for production of Hydrocarbons from the Assets or
any other matters contained in any other material furnished to Buyer by Seller or by Seller’s agents or representatives). In those situations where Seller is the operator of any of the Assets, Seller makes no warranty or representation, express
or implied, that Buyer may become operator of such Assets; it being understood that the election of operator is governed by the provisions of the applicable joint operating agreement. 
 Section 5.03 Asset Title Review. 
 Buyer may review
the information specified in Section 5.01 at Seller’s offices in Houston, Texas. Seller shall not perform any additional title work. Any existing abstracts and title opinions have not been made and will not be made current by the Seller.
Buyer specifically agrees that any conclusions made from any examination done or caused to be done have resulted and shall result from its own independent review, skill, knowledge and judgment only. 

Section 5.04 Title Adjustment. 
 There shall not exist at Closing any uncured Title Defects which exceed the Title Basket Value (as defined in Section 5.07(b) below) unless adjustments therefor have been made pursuant to the further
terms of this Agreement or Buyer has elected to waive any such Title Defects. Buyer shall notify Seller in writing of any claimed Title Defects no later than fifteen (15) days after the Execution Date or September 29, 2009
(“Title Defects Notice”). The Title Defects Notice shall set forth in reasonable detail (i) the Well and/or Lease with respect to which a claimed Title Defect is made; (ii) the nature of such claimed Title Defect;
and (iii) Buyer’s calculation of the value of each claimed Title Defect in accordance with the guidelines set forth in Section 5.06. Any Title Defect that is not identified in the Title Defects Notice shall thereafter be forever
waived and expressly assumed by Buyer and shall be deemed to have become a Permitted Encumbrance. As used in this Agreement, the following terms shall have the following meanings: 

“Title Defect” means, with respect to Seller’s interest in a Well and/or Lease, any lien,
mortgage, pledge, claim, charge, option, defect, requirement for consent to assignment and/or other encumbrance which might affect or interfere with the operation, use, ownership or value of such Well and/or Lease other than Permitted Encumbrances,
and (i) entitles the owner thereof to receive a percentage of all proceeds of production therefrom less than the Net Revenue Interest of Seller set forth on Exhibit A and Exhibit A-1, or (ii) obligates Seller to
pay costs and expenses relating to the operations on and the maintenance and development of such Well and/or Lease, as the case may be, in an amount greater than the Working Interest set forth in Exhibit A and Exhibit
A-1, without a corresponding increase in the Net Revenue Interest for such Well and/or Lease. 

  
 13 

 “Net Revenue Interest” means Seller’s interest
in and to all production of oil, gas and other minerals saved, produced and sold from a Well and/or Lease after giving effect to all valid lessor’s royalties, overriding royalties, production payments, carried interests, liens and other
encumbrances or charges against production therefrom. 
 “Working Interest” means, with
respect to a Well and/or Lease, Seller’s interest in and to the full and entire leasehold estate created under and by virtue of the Leases and all rights and obligations of every kind and character appurtenant thereto or arising therefrom,
without regard to any valid lessor’s royalty, overriding royalties, production payments, carried interests, liens, or other encumbrances or charges against production therefrom insofar as such interest in said leasehold estate is burdened with
the obligation to bear and pay costs of operations. 
 “Permitted Encumbrances” means
(i) lessor’s royalties, non-participating royalties, overriding royalties, and division orders and sales and transportation contracts containing customary terms and provisions covering oil, gas or associated liquified or gaseous
hydrocarbons, reversionary interests, and similar burdens if the net cumulative effect of such burdens does not operate to reduce the Net Revenue Interest in a Well and/or Lease to an amount less than the Net Revenue Interest set forth on
Exhibit A and Exhibit A-1 or increase the Working Interest of Well and/or Lease from that set forth in Exhibit A and Exhibit A-1 without a corresponding increase in the Net Revenue Interest;
(ii) subject to the provisions of Section 7.05 hereof, preferential rights to purchase and required non-governmental third party consents to assignments and similar agreements with respect to which prior to Closing (a) waivers or
consents are obtained from the appropriate parties, or (b) the appropriate time period for asserting such rights has expired without an exercise of such rights; (iii) liens for taxes or assessments not yet due or delinquent or, if
delinquent, that are being contested in good faith in the normal course of business; (iv) all rights to consent by, required notices to, filings with, or other actions by governmental entities in connection with the sale or conveyance of oil
and gas leases or interests therein, if the same are customarily obtained subsequent to such sale or conveyance and Buyer and Seller have no reason to believe they cannot be obtained; (v) any Title Defects Buyer may have expressly waived in
writing or which are deemed to have become Permitted Encumbrances under Section 5.04; (vi) environmental laws and regulations to the extent valid and applicable to the Assets; (vii) vendors’, carriers’, operator’s,
warehousemen’s, repairmen’s mechanics’ workmen’s, materialmen’s, construction or other like liens arising by operation of law in the ordinary course of business or incident to the construction, maintenance or operation of
any of the Assets for the period of time on or after the Effective Date only in respect of obligations which are not yet due; (viii) the lien of Seller’s lenders against any of the Assets, provided that such lien is released at or
before Closing; (ix) the lawsuits, subpoenas, audits, claims and/or demands referred to in Exhibit C; (x) the terms and provisions of any joint operating agreements, gas balancing agreements, leases, assignments, unit
agreements, and other instruments of conveyance or transfer applicable to or affecting the Assets, including the assignments and instruments of conveyance under which Seller acquired the Assets, including any right retained by a predecessor in title
of Seller to purchase hydrocarbons produced from the Assets; and (xi) all other liens, claims, charges, encumbrances, contracts, agreements, 

  
 14 

 
instruments, obligations, defects, and irregularities affecting the Assets relating to obligations not yet in default, and/or which do not prevent Buyer from receiving the proceeds of production
from the Assets, do not reduce the Net Revenue Interest of any of the Assets to less than the Net Revenue Interest set forth on Exhibit A and Exhibit A-1 and do not obligate Buyer to bear costs and expenses relating to
the maintenance, development, and operation of any of the interests in any amount greater than the Working Interest set forth on Exhibit A and Exhibit A-1 (unless the Net Revenue Interest for such Asset is greater than
the Net Revenue Interest set forth in Exhibit A and Exhibit A in the same proportion as any increase in such Working Interest). 
 “Defect Value” shall mean the amount that is determined in accordance with Section 5.06 below with respect to each Title Defect that is accepted by Seller or determined to be
a Title Defect pursuant to Section 5.05. 
 Section 5.05 Determination of Title Defects and Defect Values. 

On or before five (5) days after Seller’s timely receipt of the Title Defects Notice, Seller shall notify Buyer
whether Seller agrees with Buyer’s claimed Title Defects and/or the proposed Defect Values therefor (“Seller’s Response”). If Seller does not agree with any claimed Title Defect and/or the proposed Defect Value
therefor, then the parties shall enter into good faith negotiations and shall attempt to agree on such matters. If the parties cannot reach agreement concerning either the existence of a Title Defect or a Defect Value on or before ten (10) days
after Seller’s timely receipt of the Title Defects Notice before Closing, the parties shall mutually agree on and employ an attorney experienced in title examination in the state in which the Asset affected by the claimed Title Defect is
located to resolve all points of disagreement relating to Title Defects and Defect Values; provided, however, that if at any time any consultant so chosen fails or refuses to perform hereunder, a new consultant shall be chosen by the
parties. The cost of any such consultant shall be borne fifty percent (50%) by Seller and fifty percent (50%) by Buyer. Each party shall present a written statement of its position on the Title Defect and/or Defect Value in question to the
consultant within five (5) business days after the consultant is selected, and the consultant shall make a determination of all points of disagreement in accordance with the terms and conditions of this Agreement within three (3) business
days of receipt of such position statements. The determination by the consultant shall be conclusive and binding on the parties, and shall be enforceable against any party in any court of competent jurisdiction. If necessary, the Closing Date shall
be deferred only as to those Assets affected by any unresolved disputes regarding the existence of a Title Defect and/or the Defect Value until the consultant has made a determination of the disputed issues with respect thereto and all subsequent
dates and required activities with respect to any such Assets having reference to the Closing Date shall be correspondingly deferred; provided, however, that, unless Seller and Buyer mutually agree to the contrary, the Closing Date
shall not be deferred in any event for more than thirty (30) days beyond the original Closing Date. All Assets as to which no such dispute exists shall be conveyed to Buyer subject to the terms of this Agreement at Closing. Once the
consultant’s determination has been expressed to both parties, Seller shall have five (5) business days in which to advise Buyer in writing which of the options available to Seller under Section 5.07 below Seller elects regarding each
of the Assets as to which the consultant has made a determination. 

  
 15 

 Section 5.06 Calculation of Defect Value. 

5.06.01 Buyer’s Notice. If a Title Defect is based upon Buyer’s notice that Seller owns a lesser
interest, or the notice is from Seller or Buyer to the effect that Seller owns a greater interest than that shown on Exhibit A and Exhibit A-1, then the Purchase Price shall be reduced or increased, as appropriate, by an
amount equal to the product of (i) the allocated value of the affected Asset as set forth in Schedule 2.05 (with an adjustment for any Gas Imbalance with respect to such affected Asset), and (ii) a fraction, the numerator of which
is the amount of lesser or greater interest set forth in the notice and the denominator of which is the respective interest set forth on Exhibit A and Exhibit A-1. If the allocated value of the affected Asset as set forth
in Schedule 2.05 (with an adjustment for any Gas Imbalance with respect to such affected Asset) is a negative value, then the Purchase Price shall be reduced if Seller owns a greater interest than that shown on Exhibit A and
Exhibit A-1 and the Purchase Price shall be increased if Seller owns a lesser interest than that shown on Exhibit A and Exhibit A-1. 

5.06.02 Third Party. In the event a third party exercises an applicable preferential right of purchase, the
Purchase Price shall be reduced or increased, as appropriate, by the amount allocated to the affected Asset as set forth on Schedule 2.05 (with an adjustment for any Gas Imbalance with respect to such affected Asset) or a pro rata portion
thereof calculated in accordance with Section 5.06.01 above if the preferential right affects less than one hundred percent (100%) of an Asset, and Closing shall occur as to the remainder of the Assets, if any. If the allocated value of
the affected Asset as set forth in Schedule 2.05 (with an adjustment for any Gas Imbalance with respect to such affected Asset) is a negative value and a third party exercises an applicable preferential right of purchase, then the Purchase
Price shall be increased by the absolute value of the amount allocated to the affected Asset shown on Schedule 2.05 (with an adjustment for any Gas Imbalance with respect to such affected Asset) and if the allocated value of the affected
Asset as set forth in Schedule 2.05 (with an adjustment for any Gas Imbalance with respect to such affected Asset) is a positive value and a third party exercises an applicable preferential right of purchase, then the Purchase Price shall be
deceased by the amount allocated to the affected Asset shown on Schedule 2.05(with an adjustment for any Gas Imbalance with respect to such affected Asset). 

5.06.03 Lien, Encumbrance, or Other Charge. If a Title Defect is a lien, encumbrance or other charge upon an Asset
which is liquidated in amount, then the adjustment shall be the sum necessary to be paid to the obligee to remove the Title Defect from the affected Asset, and Buyer shall pay such sum to obligee at Closing. However, Seller reserves the right to
retain the obligation of this Title Defect and elect to challenge the validity of any such Title Defect or any portion thereof, and Buyer shall extend reasonable cooperation to Seller in such efforts at no risk or expense to Buyer. If a Title Defect
represents an obligation or burden upon the affected Asset for which the economic detriment to Buyer is not liquidated but can be estimated with reasonable certainty, the adjustment shall be the sum Seller and Buyer mutually agree upon as necessary
to compensate Buyer at Closing for the adverse economic effect which such Title Defect will have on the affected Asset. If there is a lien or encumbrance in the form of a judgment secured by a supersedeas bond or other security approved by a court
of competent jurisdiction issuing such order, it shall not be considered a Title Defect under this Agreement. 

  
 16 

 Section 5.07 Remedies for Title Defect. 

Seller shall have the right, but not the obligation, to cure any Title Defect accepted by Seller or determined to be a
Title Defect pursuant to Section 5.05 above. With respect to any Title Defect that Seller elects not to cure or that Seller fails to cure at or prior to Closing, Seller shall have the option to: 

 

	 	(a)	 exclude the Asset subject to the Title Defect from this Agreement, in which event the Purchase Price shall be reduced or increased, as appropriate,
by the value allocated to the affected Asset as set forth on Schedule 2.05 (with an adjustment for any Gas Imbalance with respect to such affected Asset) calculated in accordance with Section 5.06 above, or 

 

	 	(b)	 at the option of Seller, sell the Asset subject to such Title Defect to Buyer without adjustment to the Purchase Price and Seller shall indemnify,
defend and hold Buyer harmless from and against all liability with respect to such Title Defect or sell the Asset subject to such Title Defect to Buyer, and the Purchase Price shall be reduced or increased, as appropriate, by the Defect Value for
such Title Defect calculated in accordance with Section 5.06 above; provided, however, no indemnity or downward adjustment of the Purchase Price on account of Title Defects shall occur unless the aggregate amount of the Defect
Values determined in accordance with Section 5.06 above exceeds five percent (5%) of the Purchase Price (“Title Basket Value”), and the amount of downward adjustment shall be the aggregate amount of Defect Values
counted from the first dollar; provided, that for purposes of determination of the Title Basket Value pursuant to this Section, exercised or unexercised Preferential Rights or unobtained Consents will not be considered Title Defects.

 Section 5.08 Termination as a Remedy. 

In the event the aggregate sum of the Defect Values results in a reduction in Purchase Price in excess fifteen percent
(15%) of the Purchase Price, either Buyer or Seller may elect to terminate this Agreement, in which case neither party shall have any further liability or obligation to the other hereunder except as to (i) the return of the Performance
Deposit to Buyer, and (ii) all obligations imposed by any confidentiality agreement, which shall survive such termination and be enforceable in accordance with the terms thereof; provided, that for purposes of determination of the
aggregate sum of the Defect Values pursuant to this Section 5.08, exercised or unexercised Preferential Rights or unobtained Consents will not be considered Title Defects. 
 ARTICLE VI 
 ENVIRONMENTAL CONDITIONS 

Section 6.01 Environmental Review. 
 Prior to Closing, Buyer shall have the opportunity to conduct at its sole risk and expense an environmental assessment of the Assets. Seller will provide reasonable access for this purpose to Assets
operated by Seller; for any Asset not operated by Seller, Seller will reasonably

cooperate with Buyer in contacting the operators of any such non-operated Asset directly to arrange for access for the purposes of environmental assessment. Buyer or any of its representatives
and agents must comply with Seller’s environmental and safety rules and policies while performing any environmental assessment on Seller-operated Assets. Buyer agrees it will not disclose any information obtained in its environmental assessment
to third parties unless agreed to in writing by Seller or unless such disclosure is expressly required by applicable law or regulation or is completed pursuant to legal process of any court or governmental authority. Buyer will notify Seller in
advance of any such disclosure and will furnish Seller copies of all materials to be disclosed prior to any disclosure thereof to third parties. As soon as possible after Buyer’s receipt thereof, Buyer shall forward to Seller copies of all
reports, data, analysis, test results, remediation costs estimates, and recommended remediation procedure or other information concerning or derived from Buyer’s environmental assessment. 

Section 6.02 Presence of Wastes, NORM, Hazardous Substances, and Asbestos.

wastes, crude oil, produced water, hazardous substances, and other materials may have occurred hereon. Additionally, the Assets, including production equipment, may contain asbestos, hazardous substances, or NORM. NORM may affix or attach itself to
the inside of wells, materials, and equipment as scale or in other forms, and NORM-containing material may have been buried or otherwise disposed of on the Assets. Special procedures may be required for remediation, removing, transporting, and
disposing of asbestos, NORM, hazardous substances, and other materials from the Assets, and Buyer assumes all liability for the assessment, remediation, removal, transportation, and disposal of these materials and associated activities in accordance
with the applicable rules, regulations, and requirements of governmental agencies, unless otherwise provided in this Article VI. 
 Section

 Section 6.04 Notice of Adverse Environment Conditions. 

Buyer shall notify Seller in writing of any claimed Adverse Environmental Condition no later than fifteen (15) days
after the Execution Date or September 29, 2009, (“Environmental Defects Notice”). The Environmental Defects Notice shall (i) set forth in reasonable detail the Well and/or Lease with respect to which a claimed
Adverse Environmental Condition is made; (ii) the nature of such claimed Adverse Environmental Condition; and (iii) Buyer’s proposed calculation of the cost to remediate each claimed Adverse Environmental Condition
(“Remediation Value”). Buyer shall absolutely and forever waive its right to assert any claim or liability against Seller arising out of or in any way related to any Adverse Environmental Condition not set forth in the
Environmental Defects Notice. 
 Section 6.05 Determination of Adverse Environmental Conditions and Remediation Values.

 On or before five (5) days after Seller’s timely receipt of the Environmental Defects Notice,
Seller shall notify Buyer whether Seller agrees with Buyer’s claimed Adverse Environmental Conditions and/or the Remediation Value (“Seller’s Environmental Response”). If Seller does not agree with the claimed
Adverse Environmental Condition and/or the Remediation Value, then the parties shall enter into good faith negotiations and shall attempt to agree on such matters. If the parties cannot reach agreement concerning either the existence of an Adverse
Environmental Condition or the Remediation Value on or before ten (10) days after Seller’s timely receipt of the Environmental Defects Notice before Closing, the parties shall mutually agree on a consultant experienced in environmental
matters in the state in which the Asset affected by the claimed Adverse Environmental Condition is located to resolve all points of disagreement with respect to such matters. 

If at any time any consultant so chosen fails or refuses to perform hereunder, a new consultant shall be chosen by the
parties. The cost of any such consultant shall be borne fifty percent (50%) by Seller and fifty percent (50%) by Buyer. Each party shall present a written statement of its position on the Adverse Environmental Condition and/or the
Remediation Value in question to the consultant within five (5) business days after the consultant is selected, and the consultant shall make a determination of all points of disagreement in accordance with the terms and conditions of this
Agreement within three (3) business days of receipt of such position statements. The determination by the consultant shall be conclusive and binding on the parties, and shall be enforceable against any party in any court of competent
jurisdiction. 
 If necessary, the Closing Date shall be deferred only as to those Assets affected by any
unresolved disputes regarding the existence of an Adverse Environmental Condition and/or the Remediation Value until the consultant has made a determination of the disputed issued with respect thereto and all subsequent dates and required activities
with respect to any such Assets having reference to the Closing Date shall be correspondingly deferred; provided, however, that unless Seller and Buyer mutually agree to the contrary, the Closing Date shall not be deferred in any event
for more than thirty (30) days beyond the original Closing Date. 

  
 19 

 All Assets as to which no such dispute exists shall be conveyed to Buyer
subject to the terms of this Agreement at Closing. Once the consultant’s determination has been expressed to both parties, Seller shall have five (5) business days in which to advise Buyer in writing which of the options available to
Seller under Section 6.06 below Seller elects regarding each of the Assets as to which the consultant has made a determination that an Adverse Environmental Condition exists. 
 Section 6.06 Remedies for Adverse Environmental Conditions. 
 As to any Adverse Environmental Condition accepted by Seller or determined to be an Adverse Environmental Condition, Seller shall have the election to: 

 

	 	(a)	 remediate such Adverse Environmental Condition at Seller’s sole cost in accordance with applicable Environmental Laws, and there shall be no
adjustment to the Purchase Price in respect of such Adverse Environmental Condition and the provisions of Section 6.07 below shall thereafter apply in all respects; or 

 

	 	(b)	 reduce the Purchase Price by the applicable Remediation Value of the Lease and/or Wells affected by such Adverse Environmental Condition, in which
event Seller shall have no other or further obligation or liability in respect of such Adverse Environmental Condition and the provisions of Section 6.07 below shall thereafter apply in all respects; provided, however, no downward
adjustment of the Purchase Price on account of Adverse Environmental Conditions shall occur unless the aggregate sum of all Remediation Values exceeds five percent (5%) of the Purchase Price (“Environmental Basket
Value”), and the amount of downward adjustment shall be the aggregate sum of all Remediation Values counted from the first dollar; or 

  

	 	(c)	 delete from this Agreement the Asset which contains the Adverse Environmental Condition in which event the Purchase Price shall be reduced by the
value allocated to the affected Asset as set forth in Schedule 2.05. 

 If Seller elects
Section 6.07(a) above, Seller will exercise all reasonable efforts and diligence to complete remediation within six (6) months of the Closing Date, but any failure to complete its efforts by such time shall not relieve Seller of its duty
to satisfy its obligation hereunder. Buyer shall allow Seller and its agents and representatives such access to the Assets as is reasonably necessary for performance of remediation work. Seller will conduct such work so as not to unreasonably
interfere with Buyer’s operations. 
 Section 6.07 Termination as a Remedy. 

In the event the aggregate sum of the Remediation Values exceeds fifteen percent (15%) of the Purchase Price, either
Buyer or Seller may elect to terminate this Agreement, in which case neither party shall have any further liability or obligation to the other hereunder except as to (i) the return of the Performance Deposit to Buyer, and (ii) all
obligations imposed by any confidentiality agreement, which shall survive such termination and be enforceable in accordance with the terms thereof.

 Section 7.02 Operations Prior to Closing. 

After the date of this Agreement and prior to the Closing, Seller, in its reasoned discretion, shall use and maintain the
Assets in substantially the same manner in which they have been used and maintained prior to this Agreement. Unless Seller and Buyer otherwise agree and Buyer’s consent shall not be unreasonably withheld, Seller shall not approve any capital
work program, capital budget, capital expenditure, AFE or capital commitment relating to any Asset involving a single expenditure in excess of One Hundred Thousand and No/100 US Dollars (US$100,000.00) or aggregate expenditures in excess of Two
Million and No/100 US Dollars (US$2,000,000.00), and Seller shall carry on its activities in relation to the Assets in the ordinary course of business consistent with past practices.

supplies and consumables) or remove any improvements, equipment or property which comprise the Assets (other than the use of supplies and consumables). Seller shall promptly notify Buyer of any material matter affecting the Assets known to Seller
which arises from the date of this Agreement to the date of Closing. In the event that any expense incurred by Seller pursuant to this Section involves the payment for work performed by an affiliate of Seller, the expenses to be paid to such

	 	(f)	 Indemnification Procedures: 

(i) All claims for indemnification under this Agreement shall be asserted and resolved pursuant to this

“Indemnifying Party.” 
 (ii) In the event that a Party wishes to assert
a claim for indemnity hereunder, such Party shall with reasonable promptness provide to the Indemnifying Party a written notice of the indemnity claim it wishes to assert on behalf of itself or another Indemnified Party, including the specific
details of and specific basis under this Agreement for its indemnity claim (a “Claim Notice”). To the extent that any Losses for which indemnification is sought are asserted against or sought to be collected from an
Indemnified Party by a third party, such Claim Notice shall include a copy of all papers served on the applicable Indemnified Party with respect to such claim. The failure of any Party to provide a Claim Notice as provided in this
Section 7.04(f)(ii) shall not relieve the Indemnifying Party of its obligations under this Agreement except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to

  
 27 

 
effectively defend against the claim or otherwise prejudices the Indemnifying Party’s ability to defend against the claim. The Indemnifying Party shall have thirty (30) days from the
personal delivery or receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party (A) whether or not it disputes its liability hereunder with respect to such Losses, and/or (B) with respect to
any Losses arising out of, associated with, or relating to Third-Party Claims, whether or not it desires, at the sole cost and expense of the Indemnifying Party, to defend the Indemnified Party against any such Losses. In the event that the
Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against such Losses, the Indemnifying Party shall have the right to defend all appropriate proceedings with counsel of its own
choosing. If the Indemnified Party desires to participate in, but not control, any such defense or settlement it may do so at its sole cost and expense. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the
Indemnifying Party and its counsel in contesting any Losses that the Indemnifying Party elects to contest or, if appropriate and related to the claim in question, in making any counterclaims against the third party asserting such Losses, or any
cross-complaint against any third party (other than a Seller Indemnified Party, if the Indemnified Party is a Seller Indemnified Party; and other than a Buyer Indemnified Party, if the Indemnified Party is a Buyer Indemnified Party). Such
cooperation shall include the retention and provision to the Indemnifying Party of all records and other information that are reasonably relevant to the Losses at issue. No Third-Party Claim that is the subject of indemnification hereunder may be
settled or otherwise compromised without the prior written consent of the Indemnifying Party. No such claim may be settled or compromised by the Indemnifying Party without the prior written consent of the Indemnified Party unless such settlement or
compromise (X) entails a full and unconditional release of the Indemnified Party (and any other members of the Indemnified Party’s group, i.e., all Seller Indemnified Parties or all Buyer Indemnified Parties) without any admission or
finding of fault or liability, and (Y) does not impose on the Indemnified Party any material non-financial obligation or any financial obligation that is not fully paid by the Indemnifying Party. 

Section 7.05 Preferential Rights and Consents to Assign. 

7.05.01 Notice to Holders. If any of the Assets are subject to third party preferential purchase rights, rights of
first refusal, or similar rights (collectively “Preferential Rights”), or third party consents to assign or similar rights (collectively “Consents”) Seller shall use its commercially reasonable efforts
to (a) notify the holders of Preferential Rights and Consents that it intends to transfer such Asset to Buyer; (b) provide them with any information about the transfer of such Asset to which they are entitled; and (c) in the case of
Consents, ask the holders of the Consents to consent to the assignment of the affected Asset to Buyer. Seller shall provide Buyer with all copies of all notices and other correspondence related to all Preferential Rights and Consents and responses
(or status thereof) of such holders. 
 7.05.02 Notice to Buyer. Seller shall promptly notify Buyer
whether (a) any Preferential Rights are exercised, waived or deemed waived; (b) any Consents are denied; or (c) the requisite time periods have elapsed without any Preferential Rights being recognized or Consents being received.
Seller will not be liable to Buyer if any Preferential Rights are exercised, or any Consents are denied, except as expressly provided for in this Section 7.05. 

  
 28 

 7.05.03 Remedies Before Closing. If Seller is unable before Closing
to obtain the required Consents (other than Consents ordinarily obtained after a closing and consents on hydrocarbon sales, purchase, gathering, transportation, treating, marketing, exchange, processing and fractionating agreements which can be
terminated without penalty on thirty (30) days or less prior written notice) and waivers of all Preferential Rights, then as the sole pre-Closing remedy for same: 
  

	 	(a)	 Seller may proceed with Closing as to the Asset affected by the unwaived Preferential Rights or unobtained Consents, subject to the further
obligation of Seller and Buyer set forth in this Section 7.05 in the event that such Preferential Rights are validly exercised or such Consents are ultimately denied after Closing; or 

 

	 	(b)	 Seller may exclude the affected portion of the Assets from the transaction under this Agreement, adjust the Purchase Price by the allocated value of
the excluded Asset calculated in accordance with Section 5.06 above, and proceed with Closing as to the rest of the Assets; or 

  

	 	(c)	 In the event there are unobtained Consents affecting any of the Assets, Seller at its option may elect to terminate this Agreement, in which case
neither Buyer or Seller shall have any further liability or obligation to the other hereunder except as to (i) the return of the Performance Deposit to Buyer, and (ii) all obligations imposed by any confidentiality agreement, which shall
survive such termination and be enforceable in accordance with the terms thereof. 

 7.05.04
Remedies After Closing. 
  

	 	(a)	 Preferential Rights. After Closing, if (i) any holder of Preferential Rights alleges improper notice of sale, or improper transfer of
the affected portion of the Assets subject to such Preferential Rights, or (ii) Seller or Buyer discovers, or any third party alleges, the existence of additional Preferential Rights, Seller will use its commercially reasonable efforts to
obtain waivers of those Preferential Rights. If after Closing Seller becomes aware of the existence of such Preferential Rights, and is unable to obtain waivers of such Preferential Rights, and such Preferential Rights are not deemed waived, the
third party ultimately establishes and exercises its right and such exercise denies the Asset to Buyer, then Buyer shall reassign the affected Asset to Seller without any warranty but free of all liens, burdens and encumbrances created by, through
or under Buyer and the Allocated Value attributable to such Asset shall be paid to Seller or Buyer, as appropriate, and Seller shall thereafter satisfy all such Preferential Rights obligations and shall indemnify, defend and hold Buyer harmless from
and against any and all claims arising from or related to Seller’s satisfaction of any such Preferential Rights obligations. Rescission of the assignment of the affected Asset and receipt by Buyer or Seller of the Allocated Value of the
affected Asset shall be the sole remedy of the parties if undiscovered or alleged Preferential Rights are established and exercised after Closing. 

  
 29 

	 	(b)	 Consents. After Closing, if Seller or Buyer discover, or any third party alleges, the existence of additional or unobtained Consents, Seller
will use its commercially reasonable efforts to obtain such Consents. If after Closing Seller becomes aware of the existence of such unobtained Consent, Seller is unable to obtain such Consents or waivers of Consents (other than consents on
hydrocarbon sales, purchase, gathering, transportation, treating, marketing, exchange, processing and fractionating agreements which can be terminated without penalty on thirty (30) days or less prior written notice), and such unwaived Consents
deny the economic benefits of the affected Asset to Buyer, then Seller and Buyer shall rescind the assignment of the affected Asset under this Agreement, after which the Allocated Value of the affected Asset shall be paid to Seller or Buyer, as
appropriate, and Buyer shall immediately reassign the affected Asset to Seller without any warranty but free of all liens, burdens and encumbrances created by, through or under Buyer. Rescission of the assignment of the affected Asset and receipt by
Buyer or Seller of the Allocated Value of the affected Asset shall be the sole remedy of the parties if undiscovered or alleged Consents are established and denied after Closing. 

7.05.05 Costs/Revenues Reimbursement. Upon any reassignment by Buyer to Seller of Assets pursuant to the
provisions of 7.05.04(a) or (b) above, the parties shall reimburse each other for all costs and revenues directly associated with such affected Assets in accordance with the applicable Contract, to the extent necessary in order to restore the
parties to their respective positions as if the affected Assets had not been transferred at Closing. 
 7.05.06
Third Party Preferential Rights. If prior to Closing Seller receives a notice under a Preferential Right from a third party co-owner that such third party intends to transfer its interest in an Asset, Seller shall promptly notify Buyer of
such notice and Buyer and Seller shall mutually agree to an appropriate course of action with respect to such Preferential Right.

will be subject to any applicable royalties, overriding royalties, production payments and similar burdens on production (“Burdens”) and any preferential rights or rights to consent to assignment (“Other
Rights”), affecting the Prospect in existence as of the Effective Date, but shall be free and clear of any other Burdens or Other Rights created or established by, through or under Buyer subsequent to the Effective Date. Joint
operations will be conducted under the terms of the joint operating agreement in effect as of the Effective Date

analysis and other data in the possession or control of Seller with respect to such proposed well. Buyer shall have the right to participate by providing written notice of such to Seller within thirty (30) days after receipt of Seller’s
notice of such opportunity. Buyer shall have the right to meet with Seller’s technical personnel to discuss the Prospect identified in such Notice of Opportunity during such 30-day period. The failure by Buyer to timely respond to Seller’s
Notice of Opportunity shall be deemed a waiver by Buyer of its right to participate in such proposed well. 
 If Buyer elects to participate in the proposed well, Seller shall bear fifty percent (50%), proportionately reduced to Buyer’s working interest, of the cost of such operations, including completion
or abandonment and Seller shall receive an undivided fifty percent (50%) operating right interest in the Prospect, proportionately reduced to Buyer’s working interest, from the surface to one hundred feet (100’) below the TD of
such well, within the Prospect area, described by aliquots ( 1/4  1/4  1/4), on a form approvable by the MMS. Joint operations
will be conducted under the terms of the JOA in effect as of the Effective Date hereof. In the event there is no effective JOA, Seller and Buyer shall enter into a mutually acceptable JOA in substantially the same form as attached as Exhibit
K providing for Buyer as operator. 
 If Buyer does not elect
to participate in the proposed well, Seller shall bear one hundred percent (100%), proportionately reduced to Buyer’s working interest, of the cost of such operations, including completion or abandonment and Seller shall receive an undivided
one hundred percent (100%) operating right interest in the Prospect, proportionately reduced to Buyer’s working interest, from the surface to one hundred feet (100’) below the TD of such well, within the Prospect area, described
by aliquots ( 1/4  1/4  1/4), on a form approvable by the MMS. The assignment will be subject
to any Burdens affecting the Prospect in existence as of the Effective Date, but shall be free and clear of any other Burdens created or established by, through or under Buyer subsequent to the Effective Date. Buyer shall use its commercially
reasonable efforts to assist Seller in the drilling of such well. Buyer shall have rights to back-in after recovery of non-consent penalties to the extent stipulated in the applicable JOA. 

Any burdens, liens or other encumbrances placed on the Leases by Buyer shall be expressly subordinate to Seller’s
rights hereunder.
