4.2 Title Adjustment Procedures. 

(a) Title Defect. As used in this Agreement, the term “Title Defect” means any lien, charge,
encumbrance, obligation (including contract obligation), defect, condition or other matter (including without limitation a discrepancy in Net Revenue Interest or Working Interest) that causes a breach of a Party’s representation and warranty in
Section 4.1(a). Notwithstanding the foregoing, the following shall not be considered Title Defects: 

(1) defects based solely on a lack of information in connection with documents filed of record not contained in a
Party’s files; 
 (2) defects in the chain of title consisting of the mere failure to recite marital status
in a document or omissions of successions of heirship or estate proceedings, unless the Party alleging the defect provides clear and convincing evidence that such failure or omission has resulted in another person’s actual and superior claim of
title to the relevant Asset; 

  
 14 

 (3) defects arising out of a lack of survey, unless a survey is expressly
required by applicable laws or regulations; 
 (4) defects asserting a change in Working Interest or Net Revenue
Interest based on a change in drilling and spacing units, tract allocation or other changes in pool or unit participation occurring after the date of this Agreement; 

(5) defects arising out of lack of corporate or other entity authorization unless the Company provides a reasonable basis
for the assertion that such corporate or other entity action was not authorized and results in another person’s actual and superior claim of title to the relevant Asset; 

(6) defects based on failure to record Leases issued by the Bureau of Land Management or other Governmental Entity in the
real property records of the county in which such Lease is located; and 
 (7) defects that have been cured by
applicable laws of limitation or prescription. 
 (b) Title Benefit. As used in this Agreement, the term
“Title Benefit” shall mean any right, circumstance or condition that operates to (i) increase the Net Revenue Interest being assigned to the Company in any Lease or Well above that shown for such Lease or Well in Exhibit
C-1 and C-2 and Exhibit D-1 and D-2 to the extent the same does not cause a greater than proportionate increase in the Working Interest being assigned to the Company above that shown in Exhibit C-1 and C-2 and
Exhibit D-1 and D-2, or (ii) increase the Net Acres being assigned to the Company in any Lease to greater than that shown for such Lease in Exhibit C-1 and D-1. 

(c) Notice of Defective Interest. On or before the Defect Notice Date, a Party alleging a Title Defect shall advise
the other Party in writing of any matters that in the alleging Party’s reasonable opinion constitute a Title Defect with respect to the other Party’s title to all or any portion of its Leases, Wells and Fee Lands (“Notice of
Defective Interest”). The Notice of Defective Interest shall be in writing and contain the following: (i) a description of the alleged Title Defect(s), (ii) the Leases or Wells and Fee Lands (and the applicable zone(s) therein)
affected by the alleged Title Defect (each, a “Title Defect Property”), (iii) the Allocated Value of each Title Defect Property, (iv) supporting documents reasonably necessary (as well as any title attorney or examiner
hired by Laramie or Delta, as applicable) to verify the existence of the alleged Title Defect(s), and (v) the alleging Party’s good faith estimate of the relevant Title Defect Amount and the computations and information upon which such
estimate is based. To give the Party against whom a Title Defect is being alleged an opportunity to commence reviewing and curing Title Defects, the alleging Party agrees to use reasonable efforts to provide, on or before the end of each calendar
week prior to the Defect Notice Date, written notice of all Title Defects discovered by the alleging Party or any of its representatives during the calendar week preceding the calendar week then ending, which may be preliminary in nature and
supplemented prior to the Defect Notice Date. Laramie or Delta shall also promptly furnish the other Party with written notice of any Title Benefit which is discovered by such Party or any of its representatives while conducting title review, due
diligence or investigation with respect to the Leases or Wells. 

  
 15 

 (d) Notice of Title Benefits. On or before the Defect Notice Date,
Laramie or Delta, shall have the right, but not the obligation, to advise the other Party in writing of any matters that in Laramie’s or Delta’s, as applicable, reasonable opinion constitute a Title Benefit with respect to Laramie’s
or Delta’s, as applicable, title to all or any portion of its Leases and Wells (a “Title Benefit Notice”). The Title Benefit Notice shall be in writing and contain the following: (i) a description of the Title Benefit,
(ii) the Leases or Wells (and the applicable zone(s) therein) affected by the Title Benefit (“Title Benefit Property”), (iii) the Allocated Values of the Leases or Wells (and the applicable zone(s) therein) subject to such
Title Benefit, and (iv) Laramie’s or Delta’s, as applicable, good faith estimate of the relevant Title Benefit Amount, and the computations and information upon which such estimate is based. Laramie or Delta shall be deemed to have
waived all Title Benefits of which it has not given notice on or before the Defect Notice Date. 
 (e) Effect
of Title Benefits. The aggregate of the Title Defect Amounts (as defined in Section 4.2(h)) shall be decreased by an amount equal to the aggregate of the Title Benefit Amounts (as defined in Section 4.2(i)). 

(f) Right to Cure. Laramie or Delta, as applicable, shall have the right, but not the obligation, to attempt, at
its sole cost, to cure or remove, to the other Party’s reasonable satisfaction, any Title Defects contained in a Notice of Defective Interest from the other Party. 

(g) Remedies for Title Defects. Subject to Laramie’s or Delta’s, as applicable, continuing right to
dispute the existence of a Title Defect or the Title Defect Amount asserted with respect thereto, in the event that any Title Defect timely asserted by a Party in accordance with Section 4.2(c) actually exists and is not waived by other
Party or cured on or before Closing, Laramie or Delta, as applicable, shall convey the Title Defect Property to the Company at Closing with a reduction to the Laramie Payment or Delta Payment, as applicable, by an amount equal to the Title Defect
Amount for such Title Defect as determined pursuant to Section 4.2(h), and subject to the Aggregate Title Deductible (the “Title Defect Adjustment”). 

(h) Title Defect Amount. The “Title Defect Amount” means the amount determined in accordance with
the following methodology, terms and conditions: 
 (1) if the Parties agree on the Title Defect Amount, that
amount shall be the Title Defect Amount; 
 (2) if the Title Defect is a Lien, encumbrance or other charge which
is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount of the payment necessary to remove the Title Defect from the Title Defect Property; and 

  
 16 

 (3) if the Title Defect represents an obligation, encumbrance, burden or
charge upon or other defect in title to the Title Defect Property of a type not described in subsections (1) or (2) above, the Title Defect Amount shall be determined by taking into account the following factors: (i) any discrepancy
between (A) the Net Revenue Interest or Working Interest for any Title Defect Property and (B) the Net Revenue Interest or Working Interest stated in Exhibit C-1 and C-2 and Exhibit D-1 and D-2; (ii) the
Allocated Value of the Title Defect Property; (iii) the portion of the Title Defect Property affected by the Title Defect; (iv) the legal effect of the Title Defect; (v) the values placed upon the Title Defect by the Parties and
(vi) such other reasonable factors as are necessary to make a proper evaluation. 
 Notwithstanding anything to the contrary in this
Article 4, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of the Title Defect Property. 

(i) Title Benefit Amount. “Title Benefit Amount” means the amount determined in accordance with
the following methodology, terms and conditions: 
 (1) if the Parties agree on the amount of the Title Benefit,
that amount shall be the Title Benefit Amount; 
 (2) if the Title Benefit represents an increase between
(A) the Net Acres for any Title Benefit Property and (B) the Net Acres for such Title Benefit Property stated in Exhibit C-1 and Exhibit D-1, then the Title Benefit Amount shall be an amount equal to (x) a fraction, the
numerator of which is the Allocated Value attributable to such Title Benefit Property and the denominator of which is number of Net Acres for such Title Benefit Property stated in Exhibit C-1 and Exhibit D-1 multiplied by (y) the
difference between (I) the Net Acres for any Title Benefit Property and (II) the Net Acres for such Title Benefit Property stated in Exhibit C-1 and Exhibit D-1; and 

(3) if the Title Benefit is of a type not described above, then the applicable Title Benefit Amount shall be determined by
taking into account the following factors: (i) any discrepancy between (A) the Net Revenue Interest or Working Interest for any Title Benefit Property and (B) the Net Revenue Interest or Working Interest stated in Exhibit C-1
and C-2 and Exhibit D-1 and D-2; (ii) the Allocated Value of the Title Benefit Property; (iii) the portion of the Title Benefit Property affected by the Title Benefit; (iv) the legal effect of the Title Benefit;
and (v) such other reasonable factors as are necessary to make a proper evaluation. 
 (j) Title
Deductible. Notwithstanding anything to the contrary herein, in no event shall there be any adjustments to the Laramie Payment or Delta Payment, as applicable, or other remedies provided Laramie or Delta for any Title Defect unless the Title
Defect Amounts of all such Title Defects applicable to the Laramie Assets or Delta Assets, in the aggregate, excluding any Title Defects cured by the applicable Party, exceed a deductible in an amount equal to $2,500,000 (“Aggregate Title
Deductible”). Once the Aggregate Title Deductible has been reached as to the Laramie Assets or Delta Assets, the Company shall be entitled to adjustments to the Laramie Payment or Delta Payment, as applicable, only with respect to such
Title Defects in excess of such Aggregate Title Deductible. 

  
 17 

 4.3 Title Dispute Resolution. The Parties agree to resolve disputes
concerning the following matters pursuant to this Section 4.3: (i) the existence and scope of a Title Defect or Title Benefit, (ii) the Title Defect Amount or Title Benefit Amount, as the case may be, relating to the portion of
the Asset affected by a Title Defect or Title Benefit and (iii) the adequacy of Laramie’s or Delta’s, as applicable, Title Defect curative materials and the other Party’s reasonable satisfaction therewith (the “Title
Disputed Matters”). The Parties agree to attempt to initially resolve all disputes through good faith negotiations. If the Parties cannot resolve disputes regarding items (i), (ii) and (iii) on or before Closing, then the
Title Defect Properties affected by the Title Disputed Matter shall not be conveyed at Closing and the Laramie Payment or Delta Payment shall be reduced by the Allocated Values for such Title Defect Properties. Further, the Title Disputed Matters
will be finally determined by binding arbitration pursuant to Section 17.17. Upon receipt of the arbitrator’s decision, the Title Defect Properties shall be conveyed and the unpaid portions of the Delta Payment or Laramie Payment
shall be paid as provided in such decision. 
 4.4 Consents. The remedies set forth in this
Section 4.4 are the exclusive remedies under this Agreement for consents to assign and preferential rights to purchase. 
 (a) Consents. All required consents to assignment that are necessary for Laramie or Delta, as applicable, to execute, deliver and perform its obligations under this Agreement (each, a
“Required Consent”) are set forth on Schedule 4.4(a)(1), with respect to Laramie, and Schedule 4.4(a)(2), with respect to Delta. Laramie or Delta, as applicable, shall use reasonable efforts to obtain all Required
Consents prior to Closing. Consents and approvals which are customarily obtained post-Closing shall not be considered Required Consents. If prior to Closing, Laramie or Delta, as applicable, fails to obtain a Required Consent to assign that would
invalidate the conveyance of the Asset affected by the consent to assign or materially affect the value or use of the Asset (“Affected Asset”), then, unless waived by the other Party, the Affected Asset shall be excluded from the
sale and the Laramie Payment or Delta Payment, as applicable, shall be reduced by the Allocated Value of the Affected Asset. If the requirement to obtain the Required Consent is waived, the Parties shall continue to use reasonable efforts to obtain
such consent and shall enter into mutually acceptable arrangements between Laramie and Delta to afford the Company the benefits of the agreement containing the Required Consent. The Company shall reasonably cooperate with Laramie or Delta, as
applicable, in obtaining any Required Consent, including by providing reasonable financial assurances, but the Company shall not be required to expend funds in order to obtain such consent. 

  
 18 

 (b) Preferential Purchase Rights. All preferential rights to purchase
that are necessary for Laramie or Delta, as applicable, to execute, deliver and perform its obligations under this Agreement are set forth on Schedule 4.4(b)(1), with respect to Laramie, and Schedule 4.4(b)(2), with respect to Delta.
Prior to Closing, Laramie or Delta, as applicable, shall use reasonable efforts to give the notices required in connection with such preferential purchase rights, together with any other preferential rights to purchase discovered by the other Party
prior to Closing. If any preferential right to purchase any portion of the Assets is exercised prior to the Closing Date, then that portion of the Assets affected by such preferential purchase right shall be excluded from the Assets, and the Laramie
Payment or the Delta Payment, as applicable, shall be adjusted downward by an amount equal to the Allocated Value of such affected Assets. If by Closing, either (i) the time frame for the exercise of a preferential purchase right has not
expired and a notice of an intent not to exercise or a waiver of the preferential purchase right has not been received, or (ii) a third party exercises its preferential right to purchase, but the time frame for the consummation of such right
has not expired prior to the Closing, then Laramie or Delta, as applicable, shall retain the affected Assets and the Laramie Payment or the Delta Payment, as applicable, shall be adjusted downward by an amount equal to the Allocated Value of such
affected Assets. As to any Assets retained by Laramie or Delta hereunder, following Closing but prior to the Final Settlement Date, if a preferential right to purchase is not consummated within the time frame specified in the preferential purchase
right, or if the time frame for exercise of the preferential purchase right expires without exercise after the Closing, the owner of the affected Asset shall promptly convey the affected Asset to the Company effective as of the Effective Time (with
appropriate adjustments for proceeds from the Asset following the Effective Time net of Property Expenses relating thereto), and the Company shall pay the Party conveying the affected Asset the Allocated Value thereof pursuant to the terms of this
Agreement.

asset or property included in the Assets that: (y) in any material respect interferes with or prevents compliance by Laramie or Delta, as applicable, with any Environmental Law or the terms of any license or permit issued pursuant thereto or
(z) gives rise to or results in any common law or other liability of Laramie or Delta, as applicable, to any person that would be reasonably likely to have a Material Adverse Effect. To the Knowledge of Laramie or Delta, the Laramie Assets or
the Delta Assets, as applicable, are in compliance with Environmental Laws in all material respects. 

  
 20 

 5.3 Environmental Defect Notice. On or before the Defect Notice Date, Laramie
or Delta, as applicable, shall give written notice to the other Party of any Environmental Defects as to which each Party has knowledge prior to the Defect Notice Date (the “Environmental Defect Notice”). Laramie or Delta shall be
deemed to have waived its right to assert an Environmental Defect if it does not include such Environmental Defect in an Environmental Defect Notice delivered to the other Party, as applicable, on or before the Defect Notice Date. An Environmental
Defect Notice shall contain the following: (a) a description of the Condition in, on, under or relating to the Asset that causes the alleged Environmental Defect, (b) a description of the Asset affected by the alleged Environmental Defect
(each, an “Environmental Defect Property”), (c) the Allocated Value of each Environmental Defect Property, (d) supporting documentation reasonably necessary for Laramie or Delta, as applicable, (as well as any consultant
hired by Laramie or Delta) to verify the existence of the alleged Environmental Defect(s), and (e) the Company’s estimate of the cost to Remediate the alleged Environmental Defect (the “Environmental Defect Value”) and a

in each case, shall have the right, but not the obligation, to attempt, at its sole cost, to Remediate at any time prior to the Closing any Environmental Defects of which it has been advised by the other Party prior to the Defect Notice Date.

 5.5 Defect Adjustments. Upon delivery of a timely Environmental Defect Notice, the Parties shall proceed as
follows: 
 (a) With respect to each Environmental Defect asserted by either Party on or before the Defect Notice
Date, Laramie or Delta, as applicable, may elect, on or before the date that is two (2) days prior to the Closing Date, to: 
 (1) reach agreement with other Party on the existence of the Environmental Defect and, subject to Section 5.6(b), adjust the Laramie Payment or Delta Payment, as applicable, by the
Environmental Defect Value of the Environmental Defect Property (the “Environmental Defect Adjustment”), whereupon Laramie or Delta, as applicable, shall convey the Environmental Defect Property to the Company at Closing and the
Company shall thereafter assume all liability for Remediation of the Environmental Defect Property; or 
 (2)
challenge the existence and/or scope of the Environmental Defect and/or Environmental Defect Value asserted by the other Party pursuant to Section 5.3. If Laramie or Delta, as applicable, elects under Section 5.6 to challenge
the existence of an Environmental Defect and/or Environmental Defect Value or challenges the adequacy of any Remediation by the other Party under Section 5.4, and such dispute has not been resolved as of the Closing, then the
Environmental Defect Properties affected by the dispute shall not be conveyed at Closing, the Laramie Payment or Delta Payment shall be reduced by the Allocated Values of such Environmental Defect Properties, and the Dispute will be determined
pursuant to Section 5.6. 

  
 21 

 (b) Notwithstanding anything herein provided to the contrary, in no event
shall there be any adjustments to the Laramie Payment or Delta Payment, as applicable, or other remedies provided by Laramie or Delta, as applicable, for any Environmental Defect unless the Environmental Defect Values of all Environmental Defects
applicable to the Laramie Assets or the Delta Assets, in the aggregate, excluding any Environmental Defects cured by Laramie or Delta, respectively, as applicable, exceed a deductible in an amount equal to $2,500,000 (the “Aggregate
Environmental Deductible”). Once the Aggregate Environmental Deductible has been reached as to the Laramie Assets or the Delta Assets, the Company shall be entitled to adjustments to the Laramie Payment or the Delta Payment, as applicable,
only with respect to such Environmental Defects in excess of the Aggregate Environmental Deductible. 
 5.6 Contested
Environmental Defects. If, pursuant to Section 5.5(a)(2), Laramie or Delta, as applicable, elects to proceed under this Section 5.6 with respect to an Environmental Defect, the following matters shall be determined
pursuant to this Section 5.6: (a) the existence and scope of an Environmental Defect, (b) the Environmental Defect Value and (c) the adequacy of Laramie or Delta, as applicable, Remediation of any Environmental Defect. The
Parties agree to attempt to initially resolve all disputes through good faith negotiations. If the Parties cannot resolve disputes regarding items (a), (b) or (c) within fifteen (15) days after the Defect Notice Date or the
Closing, as applicable, the disputed matters will be finally determined by binding arbitration in accordance with the procedures set forth in Section 17.17. Upon receipt of the arbitrator’s decision, the Environmental Defect
Properties shall be conveyed and the unpaid portion of the Delta Payment or Laramie Payment, as applicable, shall be paid as provided in such decision. 
 5.7 Exclusive Remedies. The right of Laramie or Delta to have the Laramie Payment or Delta Payment, as applicable, reduced to reflect one or more Environmental Defect Adjustments pursuant to
this Article 5 shall be the exclusive right and remedy of Laramie, Delta and the Company with respect to environmental matters affecting the Assets. Notwithstanding anything herein to the contrary, if an Environmental Defect under this
Article 5 results from any matter which could also result in the breach of any representation or warranty of Laramie or Delta, as applicable, in this Agreement, then the other Party shall only be entitled to assert such matter before the
Defect Notice Date as an Environmental Defect to the extent permitted by this Article 5. The other Party shall be precluded from also asserting such matter as the basis of the breach of any such representation or warranty. 

5.8 Environmental Liabilities and Obligations; Delta Assets. 

(a) Upon Closing, the Company agrees to assume and pay, perform, fulfill and discharge all claims, costs, expenses,
liabilities and obligations accruing or relating to and release Delta, its stockholders, directors, officers, employees, agents and representatives, and their respective successors and assigns (but no other third parties) from all Losses (including
any costs of assessment, clean-up, removal and Remediation, and expenses for the modification, repair or replacement of facilities on the Lands brought or assessed by any and all persons, including any Governmental Entity but excluding any civil
fines or penalties arising from acts or omissions of Delta before the Closing), as a result of any personal injury, illness or death, any damage to, destruction or loss of property, and any damage to natural resources (including soil, air, surface
water or groundwater) to the extent any of the foregoing directly or indirectly is caused by or otherwise involves any Condition of the Delta Assets whether created or attributable to periods either before or after the Effective Time, including, but
not limited to, the presence, disposal or release of any Hazardous Material of any kind in, on or under the Delta Assets or the Delta Lands (collectively, “Company’s Delta Environmental Liabilities”). 

  
 22 

 (b) Notwithstanding the provisions of this Section 5.8(b) or any
other provision in the Agreement, the Company’s Delta Environmental Liabilities shall be limited to, and the Company shall only assume as part of the Assumed Liabilities, those claims that (i) are allowed claims in the Bankruptcy Cases,
only to the extent that Delta or any of Delta’s subsidiaries, as applicable, is obligated by a final court order to make any payments on or provide other consideration with respect to such claims, (ii) are not allowed claims in the Chapter
11 Cases and not discharged in the Chapter 11 Cases or (iii) are claims for indemnification by Delta’s officers or directors against Delta with respect to civil claims under CERCLA or any state analog to the extent not covered by
Delta’s available insurance; provided, however, that in the case of each of clauses (i), (ii) and (iii) the Company shall not assume liability for Losses relating to the shipment or other transportation of Hazardous Materials for
treatment, storage or disposal at any off-site location made by or on behalf of Delta (collectively, such Assumed Liabilities being the “Pre-Effective Time Delta Environmental Claims”). 

Promptly after its receipt of notice of the commencement of any action or filing of any proof or notice of claim relating to a
Pre-Effective Time Delta Environmental Claim, Delta shall provide the Company notice in writing of the commencement or filing thereof, describing such claim, the amount thereof and the basis thereof, and including a copy of any documents, motions or
pleadings filed in connection therewith; provided that any failure to so notify or any delay in notifying the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is prejudiced by such failure or
delay. With respect to all Pre-Effective Time Delta Environmental Claims, (a) to the extent that the Company has standing to defend against and object to any Pre-Effective Time Delta Environmental Claims, the Company shall have the right to
assert any defense or objection of Delta or any of Delta’s subsidiaries or their respective estates, as applicable, at the Company’s expense, (b) Delta and Delta’s subsidiaries, as applicable, shall reasonably cooperate at the
Company’s expense in connection with such defense and objection, including, without limitation (i) providing reasonable access to documents and Delta’s and its subsidiaries’ employees, officers, professionals, consultants and any
other agents or representatives (collectively, “Delta’s Representatives”) and (ii) attending and participating in or assisting with, and causing Delta’s Representatives to attend and participate in or otherwise assist
with, the preparation of and conduct of any discovery and other legal, judicial or administrative proceedings relating to Pre-Effective Time Delta Environmental Claims as witnesses or otherwise and (c) Delta and its subsidiaries, as applicable,
shall not settle any Pre-Effective Time Delta Environmental Claims without the prior written consent of the Company, which consent may be withheld or granted in the Company’s sole discretion; provided, further, that if the Company does not have
standing as described herein, Delta and Delta’s subsidiaries, as applicable, shall as directed by the Company and under the Company’s control, use their respective reasonable best efforts to defend against such claims using counsel
appointed by the Company, at the Company’s expense, to (A) assert any defense against or object to Pre-Effective Time Delta Environmental Claims, (B) reasonably cooperate and consult with the Company in, and keep the Company fully
informed with respect to, all aspects of such defense and objection, including without limitation, (i) providing reasonable access to Delta’s Representatives and to Delta’s and Delta’s Representatives’ documents, whether in
electronic form or otherwise, and (ii) permitting the Company to attend and participate in or assist with, and causing Delta’s Representatives to permit the Company to attend, participate in or otherwise assist with, the preparation of and
conduct of any discovery and other legal, judicial or administrative proceedings relating to Pre-Effective Time Delta Environmental Claims as witnesses or otherwise and (C) Delta and its subsidiaries, as applicable, shall not settle any
Pre-Effective Time Delta Environmental Claims without the prior written consent of the Company, which consent may be withheld or granted in the Company’s sole discretion.

Hydrocarbons and containing a “take or pay,” advance payment or similar provision, gas balancing agreement or any other arrangement, to deliver any material amounts of Hydrocarbons without then or thereafter receiving full payment
therefor, or to make payment for any material amounts of Hydrocarbons already produced and sold, in each case with respect to the Delta Assets. 
 9.16 Surface Access. No surface use or access agreements that are currently in force and effect would materially interfere with oil and gas operations on the Delta Leases as currently

condemnation or the threat of condemnation.

will rely solely on the terms of this Agreement and the Other Agreements and upon its independent analysis, evaluation and investigation of, and judgment with respect to, the business, economic, legal, tax or other consequences of the Transaction

enjoins or otherwise prohibits in any material respect the implementation or performance of the Plan or this Agreement in a manner adverse to the interests of Delta or the Company. 

9.21 No Other Representations or Warranties; Disclosed Materials. Except for the representations and warranties contained
in this Agreement (as qualified by the Schedules) and the documents assigning the Delta Assets, Delta makes no other (and Laramie acknowledges that it is not relying upon any) express or implied representation or warranty with respect to Delta
(including the value, condition or use of any of the Delta Assets), the Transaction or the transactions contemplated by the Other Agreements, and Delta disclaims any other representations or warranties not contained in this Agreement, whether made
by Delta, or any of its respective officers, directors, shareholders, employees or agents. Except for the representations and warranties contained in this Agreement (as qualified by the Schedules), the disclosure of any matter or item in the
Schedules shall not be deemed to constitute an acknowledgement that any such matter would or would reasonably be expected to be material or to result in a Material Adverse Effect.

Parties.

Delta Payment, as applicable, shall be reduced by the estimated cost to repair such Asset (with equipment of similar utility), less all insurance proceeds which shall be payable to the Company, up to the Allocated Value thereof (the reduction being
the “Net Casualty Loss”). The Party suffering the Casualty Loss, at its sole option, may elect to cure such Casualty Loss and, in such event, such Party shall be entitled to all related insurance proceeds. If a Party suffering the
Casualty Loss elects to cure such Casualty Loss, such Party may replace any personal property that is the subject of a Casualty Loss with equipment of similar grade and utility, or replace any real property with real property of similar nature and
kind if such property is acceptable to the Company. If a Party suffering the Casualty Loss elects to cure such Casualty Loss, and the Casualty Loss is cured to the Company’s reasonable satisfaction, the Company shall accept the contribution of
the affected Asset at Closing for the Allocated Value thereof. 
 (c) Master Lease Agreement for Mega Vega
Station Compressors. The Parties agree to use reasonable business efforts (not including the payment of money) to renegotiate, prior to Closing and on terms reasonably acceptable to all Parties, the terms of that certain Master Lease Agreement,
dated July 30, 2008, between Delta and US Bankcorp Equipment Finance Inc. regarding two compressors located at the Mega Vega Station. 
 (d) Further Assurances. From time to time after Closing, Delta, Laramie and the Company shall each execute, acknowledge and deliver to the other such further instruments and take such other action
as may be reasonably requested in order to accomplish more effectively the purposes of the Transaction and the transactions contemplated by the Other Agreements.

(with respect to the Laramie Assets) or Delta (with respect to the Delta Assets), as applicable, a portion of the Property Tax for the Straddle Period determined by multiplying the Property Tax for the Straddle Period by a fraction, the numerator of
which shall be the number of days in the Straddle Period prior to the Effective Time and the denominator of which shall be the number of days in the Straddle Period. The remaining portion of the Property Tax for the Straddle Period shall be
allocated to the Company. The portion of the Property Taxes for the Straddle Period allocable to Laramie and Delta, respectively, shall be taken into account as provided in Section 15.1. For any purpose as may be necessary under this
Agreement, Property Taxes levied for 2012 (and due and payable in 2013) shall be (a) if the actual Property Tax levy for 2012 has not been made prior to the calculation of the Laramie Payment and Delta Payment, as applicable, estimated based on
the 2011 mill levy without regard to the actual 2012 mill levy or assessment and (b) otherwise shall be based on the actual 2012 mill levy. Any estimate made pursuant to clause (a) of the previous sentence shall be final, and no further
adjustment to the Laramie Payment and Delta Payment, as applicable, shall be made with respect to an apportioned Property Tax based on the actual 2012 mill levy, valuation, equalization, assessment or a revised determination of 2011 production. All
Property Taxes with respect to taxable periods beginning on or after the Effective Time shall be for the Company’s account. Laramie or Delta, as applicable, shall timely file or cause to be filed all required Tax Returns for, related to or
incident to Property Taxes that are due on or prior to the Closing Date and shall timely pay or cause to be paid all Taxes due with respect thereto. The Company shall timely file or cause to be filed all required reports and returns for, related to,
or incident to Property Taxes for any Straddle Period that are due after the Closing Date and shall timely pay or cause to be paid to the taxing authorities all Property Taxes for any taxable period including the Closing Date. Any penalties,
additions to Tax, or interest levied or assessed with respect to any failure of the Company to comply with the previous sentence shall be allocated to, and shall be payable by, the Company. 

11.4 Transfer Taxes. The Company shall be liable for, any Transfer Taxes required to be paid in connection with the
transactions contemplated by this Agreement that are not eliminated through the application of section 1146(a) of the Bankruptcy Code. The Company shall timely file or cause to be filed all required reports and returns for, related to, or incident
to such Transfer Taxes and shall timely pay or cause to be paid to the taxing authorities all Transfer Taxes for any such Transfer Tax period during which the Effective Time occurs. Any penalties, additions to Tax, or interest levied or assessed
with respect to any failure of the Company to comply with the previous sentence shall be allocated to, and shall be payable by, the Company. 
 11.5 Post-Closing Tax Matters. After the Closing Date, each of the Company and Laramie or Delta, as applicable, shall: 

(a) reasonably assist the other in preparing any Tax returns with respect to any Tax incurred or imposed, or required to
be filed, in connection with the Transaction and the transactions contemplated by the Other Agreements, and in qualifying for any exemption or reduction in Tax that may be available; 

(b) reasonably cooperate in preparing for any audits or examinations by, or disputes with, taxing authorities regarding
any Tax incurred or imposed in connection with the Transaction and the transactions contemplated by the Other Agreements; 

  
 48 

 (c) make available to the other, and to any taxing authority as reasonably
requested, any information, records, and documents relating to a Tax incurred or imposed in connection with the Transaction and the transactions contemplated by the Other Agreements; and 

(d) provide timely notice to the other in writing of any pending or threatened Tax audit, examination, or assessment that
could reasonably be expected to affect the other’s Tax liability under applicable law, this Agreement or the Other Agreements, and to promptly furnish the other with copies of all correspondence with respect to any such Tax audit, examination,
or assessment.

 50 

 ARTICLE 13 
 RIGHT OF TERMINATION 
 13.1 Termination. This Agreement may
be terminated in accordance with the following provisions: 
 (a) by mutual consent of Laramie and Delta;

 (b) by Laramie or Delta if any of the conditions in Section 12.1 is not satisfied and the Party
seeking termination is not in material breach of this Agreement such that the other Party would not be required to close; 
 (c) by Delta, at any time prior to the Closing Date, if Delta’s board of directors determines that its duties under applicable Law require it to terminate this Agreement in order to enter into an
alternative transaction; 
 (d) by Laramie, if Delta files with the Bankruptcy Court any document, or otherwise
states in any press release, SEC filing or similar publicly available and disseminated document, that Delta has decided to pursue, or to seek the Court’s approval of, any Acquisition Proposal (including any alternative plan) between or
involving Delta, or any of the Debtors, and any entity other than Laramie, the Company or one of their affiliates; 
 (e) by Laramie or the Company upon any breach by Delta of any covenant, representation or warranty that is not cured by the earlier of 5 days after notice of breach or Closing;

 51 

 13.2 Liabilities Upon Termination. 

(a) Laramie’s Default. If Closing has not occurred (i) because Delta has terminated this Agreement under
Section 13.1(f), or (ii) if Laramie and Delta have consented to termination under Section 13.1(a) under terms of consent that provide for payment of liquidated damages to Delta, then Delta shall be entitled to immediate
payment by Laramie of liquidated damages of $5,000,000. In the event of a default by Laramie or the Company (caused by Laramie’s failure to perform) as a result of which the Closing and consummation of the Transaction herein contemplated do not
occur, the Parties agree that it would be impractical and extremely difficult to estimate the damages which Delta may suffer. Therefore, the Parties do hereby agree that a reasonable estimate of the total net detriment that Delta would suffer in the
event that Laramie or the Company defaults (as a result of Laramie’s failure to perform) and fails to complete the Transaction is and shall be, as Delta’s sole and exclusive remedy (whether at law or in equity), the right to receive
payment of the sum of $5,000,000. The payment and performance of the above as liquidated damages is not intended as a forfeiture or penalty within the meaning of applicable law. Upon default by Laramie or the Company (caused by Laramie’s
failure to perform) hereunder, this Agreement shall be terminated, and neither party shall have any further rights or obligations hereunder (except for indemnification obligations which specifically survive the termination of this Agreement), except
the right of Delta to be paid the amount of liquidated damages set forth in this subsection 13.2(a). 
 (b)
Delta’s Default. If Closing has not occurred because (i) Laramie has terminated this Agreement under Section 13.1 (d), (e) or (g), (ii) Delta has terminated this Agreement under Section 13.1(c) or
(g), (iii) the Company has terminated this Agreement under Section 13.1(e) or (g), (iv) Laramie and Delta have consented to termination under Section 13.1(a) under terms of consent that provide for payment of
the Break-up Fee to Laramie, (v) Laramie has terminated this Agreement under Section 13.1 (b) for non-satisfaction of any of the conditions set forth in Section 12.1(d) (but only if Laramie has used good faith
efforts to effect the Closing), (f) (but only if the Plan has been amended in a public filing and such amendment is materially adverse to Laramie), (h) (but only if Laramie has used good faith efforts to effect the Closing),
(j), or (k), then Laramie shall be entitled to immediate payment by Delta of the $1,500,000 Break-up Fee, and the Break-up Fee Order shall so provide. 
 ARTICLE 14

POST-CLOSING OBLIGATIONS 
 15.1 Final Settlement. Each of the Laramie Payment and the Delta Payment shall be further adjusted according to this Section 15.1 without duplication, as applicable to the
Laramie Assets and Delta Assets respectively. Laramie and Delta, as applicable, shall deliver to the other Party and the Company as soon as practicable after the Closing, but in no event later than 30 days after Closing, a draft settlement
statement (the “Final Settlement Statement”) that shall set forth the adjusted Laramie Payment and Delta Payment, respectively, reflecting each adjustment in accordance with Sections 2.2 and 15.1. The Laramie Payment
shall be adjusted, with respect to the Laramie Assets, and the Delta Payment shall be adjusted, with respect to the Delta Assets, by the following: 

  
 53 

 (a) Proration of Costs and Revenues. The Company shall be entitled to
all production of Hydrocarbons from or attributable to the Laramie Assets and the Delta Assets at and after the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with
respect to the Assets at or after the Effective Time, and shall be responsible for (and entitled to any refunds with respect to) all Property Expenses (as defined in Section 15.1(b) below) incurred at and after the Effective Time.
Laramie and Delta, as applicable, shall be entitled to all Hydrocarbon production from or attributable to the Laramie Assets or the Delta Assets prior to the Effective Time (and all products and proceeds attributable thereto), and to all other
income, proceeds, receipts and credits earned with respect to the Assets prior to the Effective Time, and shall be responsible for (and entitled to any refunds with respect to) all Property Expenses incurred prior to the Effective Time. The terms
“earned” and “incurred”, as used in this Agreement, shall be interpreted in accordance with generally accepted accounting principles (“GAAP”) and Council of Petroleum Accountants Society
(“COPAS”) standards, and utilizing the “sales method” of revenue accounting, except as otherwise specified herein. For purposes of allocating production (and accounts receivable with respect thereto), under this
Section 15.1(a), (i) liquid Hydrocarbons, including natural gas liquids, shall be deemed to be “from or attributable to” the Leases, Lands, and Wells when they pass through the pipeline connecting into the storage
facilities into which they are run or into tanks connected to the Wells and (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Leases, Lands, and Wells when they pass through the royalty measurement meters,
delivery point sales meters or custody transfer meters on the gathering lines or pipelines through which they are transported (whichever meter is closest to the well). Laramie and Delta, as applicable, shall utilize reasonable interpolative
procedures, consistent with industry practice, to arrive at an allocation of production when exact meter readings or gauging and strapping data are not available. As part of the Final Settlement Statement, Laramie and Delta, as applicable, shall
provide to the Company all data necessary to support any estimated allocation for purposes of establishing the Final Payment. 
 (b) Property Expenses. The term “Property Expenses” means (i) all capital expenses and operating expenses incurred in the ownership, development and operation of the Assets in
the ordinary course of business and, where applicable, in accordance with any relevant operating agreement, if any, and (ii) all Lease rental and maintenance costs, net profit payments, royalties, overriding royalties and other similar burdens
incurred in connection with the Leases or the production and sale of Hydrocarbons therefrom (collectively, “Royalty Liabilities”), but excluding Production Taxes. Property Expenses shall include overhead for the period between the
Effective Time and the Closing Date based upon the applicable joint operating agreement. 
 (c) Upward
Adjustments. The Laramie Payment and the Delta Payment each shall be adjusted upward by the following: 

  
 54 

 (1) To the extent that there are any pipeline imbalances, if the net of such
imbalances is an overdelivery imbalance (that is, at the Effective Time, Laramie or Delta has delivered more gas to the pipeline than the pipeline has redelivered for such Party), the Laramie Payment or Delta Payment, as applicable, shall be
adjusted upward by the first-of-the-month price of spot gas delivered to pipelines for Colorado Interstate Gas Company (Rocky Mountains) as reported in Inside F.E.R.C.’s Gas Market Report for the month in which the Effective Time occurs
(the “Imbalance Spot Price”) times the net overdelivery imbalance in MMbtus. In the event such publication shall cease to be published, the Parties shall select a comparable publication; and 

(2) An amount equal to the aggregate Severance Taxes (including related withholding taxes) and Property Taxes, in each
case for the portion of the Straddle Period at and after the Effective Time and paid by Laramie or Delta prior to the Closing, to such Party is liable for such Taxes pursuant to Article 11. 

(d) Downward Adjustments. The Laramie Payment or the Delta Payment each shall be adjusted downward by the
following: 
 (1) To the extent that there are any pipeline imbalances, if the net of such imbalances is an
underdelivery imbalance (that is, at the Effective Time, Laramie or Delta has delivered less gas to the pipeline than the pipeline has redelivered for such Party), the Laramie Payment or Delta Payment, as applicable, shall be adjusted downward by
the Imbalance Spot Price times the net underdelivery imbalance in MMbtus. In the event such publication shall cease to be published, the Parties shall select a comparable publication; 

(2) The value of any Casualty Loss pursuant to Section 10.4(b); 

(3) An amount equal to the revenue held in suspense by Laramie or Delta, as applicable, for royalties, overriding
royalties and similar leasehold burdens and handled in accordance with Section 15.3; and 
 (4) An
amount equal to the aggregate unpaid Severance Taxes and Property Taxes, in each case for taxable periods ending prior to the Effective Time or for the portion of the Straddle Period prior to the Effective Time, to the extent allocable to Laramie or
Delta, as applicable, pursuant to Article 11. 
 (e) Well Imbalance Adjustments. Laramie and Delta
agree that the Laramie Payment and the Delta Payment will be adjusted downward or upward, as appropriate, by an amount equal to the well imbalances existing as of the Effective Time multiplied by the Imbalance Spot Price. 

  
 55 

 (f) The Final Settlement Statement shall show the calculation of all
adjustments and the final amounts of each such Payment (the “Final Payments”). As soon as practicable after receipt of the Final Settlement Statement, but in no event later than on or before 15 days after receipt of each
Party’s proposed Final Settlement Statement, each Party shall deliver to the other Party a written report containing any changes that it proposes to make to the other Party’s Final Settlement Statement. A Party’s failure to deliver to
the other Party a written report detailing proposed changes to the Final Settlement Statement by that date shall be deemed an acceptance by such Party of the Final Settlement Statement as submitted by the other Party. The Parties shall agree with
respect to the changes proposed by the Parties, if any, no later than 30 days after receipt of each Party’s proposed Final Settlement Statement. The date upon which such agreement is reached or upon which each Final Payment is established shall
be herein called the “Final Settlement Date.” If the Final Payment is more than the Closing Amount received by Laramie or Delta, then the Company shall pay Laramie or Delta, as applicable, the amount of such difference. If the Final
Payment is less than the Closing Amount, then Laramie or Delta, as applicable, shall pay to the Company the amount of such difference. In either event, payment shall be made by wire transfer in immediately available funds. Payment by Laramie, Delta
or the Company, as the case may be, shall be within 5 days of the Final Settlement Date. 
 15.2 Records.

 (a) As soon as is reasonably practicable after the Closing Date (and in no case later than five (5) days
after Closing), Laramie and Delta shall deliver to the Company, at the Company’s expense, the Laramie Records and the Delta Records, as applicable. The Company shall preserve such Records until the earlier of (A) seven years after the
Closing Date; (B) the required retention period required by any United States or foreign legal requirement; (C) the conclusion of all bankruptcy proceedings relating to the Chapter 11 Cases and (D) in the case of Records relating to
Taxes, the expiration of the statute of limitations applicable to such Taxes. 
 (b) After the Closing Date, the
Company shall provide to Laramie and Delta and their Representatives (after reasonable notice and during normal business hours and without charge) access to, including electronic and computer access and the right to make copies (at such requesting
Party’s sole cost and expense) of, all Records included in the Assets to the extent that such Records relate to any period prior to the Closing Date and are not already in the possession of such requesting Party. the Company shall preserve such
Records until the later of (A) seven years after the Closing Date; (B) the required retention period required by any United States or foreign legal requirement; (C) the conclusion of all bankruptcy proceedings relating to the Chapter
11 Cases or (D) in the case of Records relating to Taxes, the expiration of the statute of limitations applicable to such Taxes. Such access shall include access to any information in electronic form to the extent reasonably available. Prior to
destroying any Records included in the Assets for periods prior to the Closing, the Company shall notify Laramie and Delta at least 30 days in advance of any such proposed destruction of its intent to destroy such Records, and the company will
permit the Party that provided the such Records to retain such Records. With respect to any litigation and claims that are Excluded Assets, the Company shall render reasonable assistance that Laramie or Delta, as applicable, may request in defending
such litigation or claim and shall make available employees who are most knowledgeable about the matter in question, in each case, at the requesting Party’s sole cost and expense and only at such time, and in such manner, so as not to interfere
with the normal operations of the Company or its affiliates following the Closing Date. 

  
 56 

 15.3 Suspense Accounts and Division of Interest. At the Closing, each of
Laramie and Delta will provide to the Company (a) information regarding all of Laramie’s or Delta’s, as applicable, accounts holding moneys in suspense together with a written explanation (as contained in Laramie or Delta, as
applicable, files) of why such moneys are held in suspense or other information identifying the proper disposition of such moneys and (b) Laramie’s or Delta’s, as applicable, division of interest and all supporting documentation
regarding those royalty owners and working interest owners in the Leases for whom Laramie’s or Delta’s, as applicable, disburses proceeds of production. The Company agrees to take and apply such moneys in a manner consistent with prudent
oil and gas business practices and the information supplied by Laramie’s or Delta’s, as applicable, and to indemnify Laramie’s or Delta’s, as applicable, against any claim relating to the failure to pay such funds after the
Closing. 
 15.4 Carry Agreement Wells. As soon as reasonably practicable after the Closing, the Company and Delta
each shall use reasonable business efforts (which shall not include any obligation to pay money) to obtain EnCana’s consent to the assignment to Delta of the Forward Carry Wells. In the event EnCana agrees and consents to the assignment to
Delta of the Forward Carry Wells, the Economic Interest Agreement shall terminate and be of no further force and effect upon the effectiveness of the assignment to Delta of the Forward Carry Wells.

(3) From and after the Closing, indemnification under Section 16.2 shall be the sole and exclusive remedy

 59 

 16.3 Procedure. The indemnifications contained in Section 16.2
shall be implemented as follows: 
 (a) Claim Notice. The Party seeking indemnification under the terms of
this Agreement (“Indemnified Party”) shall submit a written “Claim Notice” to the other Party (“Indemnifying Party”) which, to be effective, must be delivered prior to the end of the Survival Period
and must state: (i) the amount of each payment claimed by an Indemnified Party to be owing, (ii) the basis for such claim, with reasonably available supporting documentation, and (iii) a list identifying to the extent reasonably
possible each separate item of Loss for which payment is so claimed. The amount claimed shall be paid by the Indemnifying Party to the extent required herein within twenty (20) days after receipt of the Claim Notice, or after the amount of such
payment has been finally established as provided in Section 16.3(c), whichever last occurs. 
 (b)
Information. Within twenty (20) days after the Indemnified Party receives notice of a claim or legal action by a third party that may result in a Loss for which indemnification may be sought under this Article 16 (a
“Claim”), the Indemnified Party shall give written notice of such Claim to the Indemnifying Party; provided, however, that the failure to give such notice shall not relieve the Indemnifying Party of its obligations hereunder
except to the extent such failure is prejudicial to the Indemnifying Party. If the Indemnifying Party or its counsel so requests, the Indemnified Party shall furnish the Indemnifying Party with copies of all pleadings and other information with
respect to such Claim. At the election of the Indemnifying Party, which must be made within twenty (20) days after receipt of such notice and not thereafter, the Indemnified Party shall permit the Indemnifying Party to assume control of such
Claim (to the extent only that such Claim, legal action or other matter relates to a Loss for which the Indemnifying Party is liable), including the determination of all appropriate actions, the negotiation of settlements on behalf of the
Indemnified Party, and the conduct of litigation through attorneys of the Indemnifying Party’s choice; provided, however, that no such settlement can result in any liability or cost to the Indemnified Party for which it is entitled to be
indemnified hereunder without its consent, which consent shall not be unreasonably withheld or delayed. If the Indemnifying Party elects to assume control, (i) all reasonable expenses incurred by the Indemnified Party in connection with the
investigation or defense of the Claim, legal action or other matter prior to the time the Indemnifying Party assumes control shall be reimbursed and paid by the Indemnifying Party, (ii) any expenses incurred by the Indemnified Party thereafter
for investigation or defense of the matter shall be borne by the Indemnified Party except for reasonable expenses incurred in connection with providing information or assistance to the Indemnifying Party as required by subsection (iii), and
(iii) the Indemnified Party shall give all reasonable information and assistance, other than pecuniary, that the Indemnifying Party shall deem necessary to the proper defense of such Claim, legal action, or other matter but shall be reimbursed
and paid for such expenses as provided for in subsection (ii). Before such election is made or in the absence of such an election, the Indemnified Party shall defend any claim, legal action or other matter and shall be reimbursed and paid by the
Indemnifying Party for all reasonable expenses incurred in such defense. Before such election is made or in the absence of such election, the Indemnified Party may settle any Claim, legal action or other matter for which notice has been provided as
required by Section 16.3(a), but only with the consent of the Indemnifying Party, which consent may not be unreasonably withheld. If such a Claim requires immediate action, both the Indemnified Party and the Indemnifying Party will
cooperate in good faith to take appropriate action so as not to jeopardize the defense of such Claim or either Party’s position with respect to such Claim. 

  
 60 

 (c) Dispute. If the existence of a valid Claim or amount to be paid
by an Indemnifying Party is in dispute, the Parties agree to submit determination of the existence of a valid Claim or the amount to be paid pursuant to the Claim Notice to binding arbitration pursuant to the provisions of Section 16.16
except as otherwise provided in this Section 16.3. Any payment due pursuant to the arbitration shall be made within ten (10) days of the arbitrators’ decision. 

16.4 No Insurance; Subrogation. The indemnification provided in this Article 16 shall not be construed as a
form of insurance. The Company and Laramie or Delta, as applicable, hereby waive for themselves, their successors or assigns, including, without limitation, any insurers, any rights to subrogation for Losses for which each of them is respectively
liable or against which each respectively indemnifies the other, and, if required by applicable policies, the Company and Laramie or Delta, as applicable, shall obtain a waiver of such subrogation from their respective insurers. 

16.5 Reductions in Losses. Each Indemnified Party shall use commercially reasonable efforts to mitigate any Losses,
including by maintaining insurance coverage with respect to the Assets and making claims relating to the Assets thereunder. The amount of any Losses for which an Indemnified Person is entitled to indemnity under this Article 16 shall be
reduced by (a) the amount of insurance proceeds realized by the Indemnified Person or its affiliates with respect to such Losses, and (b) any Tax reductions or other benefits actually or likely to be received by the Indemnified Party in
connection with the Losses, after giving effect to any related Tax detriment. 
 16.6 Reservation as to
Non-Parties. Nothing herein is intended to limit or otherwise waive any recourse the Company or Laramie or Delta, as applicable, may have against any third party for any obligations or liabilities that may be incurred with respect to the
Assets.

Agreement, or the Other Agreements, any provision thereof, the alleged breach of any such provision or in any way relating to the subject matter of this Agreement, the Other Agreements, or the relationship between the parties created by this
Agreement or the Other Agreements, involving the Parties and/or their respective representatives (all of which are referred to herein as “Disputes”), even though some or all of such Disputes allegedly are extra contractual in
nature, whether such Disputes sound in contract, tort, or otherwise, at law or in equity, under state, federal or foreign law, whether provided by statute or the common law, for damages or any other relief, shall be resolved by binding arbitration
in accordance with this Section 17.17. 

  
 67 

 (c) The validity, construction, and interpretation of this
Section 17.17, and all procedural aspects of the arbitration conducted pursuant to this Section 17.17, including but not limited to, the determination of the issues that are subject to arbitration (i.e., arbitrability), the
scope of the arbitrable issues, allegations of “fraud in the inducement” to enter into any this Agreement, the Other Agreements , or this arbitration provision, allegations of waiver, laches, delay or other defenses to arbitrability, and
the rules governing the conduct of the arbitration shall be decided by the arbitrators. The arbitration shall be administered by the American Arbitration Association (the “AAA”), and shall be conducted pursuant to the Commercial
Arbitration Rules of the AAA, as modified by the Agreement. In deciding the substance of the parties’ Disputes, the arbitrators shall refer to the substantive laws of the State of Colorado for guidance (excluding Colorado choice of law
principles that might call for the application of some other state’s law). Notwithstanding any other provision in this Section 17.17 to the contrary, and except in connection with any damages incurred by third parties for which
indemnification is sought under the terms of this Agreement, the parties expressly agree that the arbitrators shall have absolutely no authority to award consequential, incidental, special, treble, exemplary or punitive damages of any type under any
circumstances regardless of whether such damages may be available under Colorado law, the law of any other state, or federal or foreign law, or under the Commercial Arbitration Rules of the AAA, the Parties hereby waiving their right, if any, to
recover consequential, incidental, special, treble, exemplary or punitive damages in connection with any such Disputes. 
 (d) The arbitration proceeding shall be conducted in Denver, Colorado, before a panel of three arbitrators appointed in accordance with the Commercial Arbitration Rules of the AAA consisting of persons
from any of the following categories: (i) attorneys having practiced in the area of oil and gas law for at least ten years, (ii) engineers with at least ten years of experience in the oil and gas industry or (iii) certified public
accountants with at least ten years of experience in the oil and gas industry dealing with joint interest billings; provided, however, that (A) if the dispute relates solely to an issue that predominantly relates to accounting matters,
all three arbitrators chosen shall be accountants, and (B) if the dispute relates solely to title issues, all three arbitrators chosen shall be attorneys experienced in title examination. The arbitrators shall conduct a hearing as soon as
reasonably practicable after appointment of the third arbitrator, and a final decision completely disposing of all Disputes that are the subject of the arbitration proceedings shall be rendered by the arbitrators within twenty (20) days after
the hearing, to the extent reasonably practicable. The arbitrators’ ultimate decision after the final hearing shall be in writing. In case the arbitrators award monetary damages to either party, the arbitrators shall certify in their award
that, except in connection with any damages incurred by third parties for which indemnification is sought under the terms of this Agreement, they have not included any consequential, incidental, special, treble, exemplary or punitive damages.

  
 68 

 (e) The arbitrators shall designate a prevailing party in their final award.
Pursuant to this determination, the arbitrators shall award to the prevailing party its attorneys’ fees, costs and expenses of the arbitration (including the arbitrators’ fees and expenses) in full. 

(f) To the fullest extent permitted by law, the arbitration proceeding and the arbitrators’ award shall be maintained
in confidence by the parties. 
 (g) The award of the arbitrators shall be binding upon the parties and final and
non-appealable to the maximum extent permitted by law, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any party as a final judgment of such court.

Subscription Agent will be returned, without interest, as soon as practicable. 
 (a) EXERCISE OF BASIC SUBSCRIPTION PRIVILEGE:

 I apply for                    shares x
$0.33 = $                  
     (no.
of new shares) (subscription price) (amount enclosed) 
 (b) EXERCISE OF OVER-SUBSCRIPTION PRIVILEGE: 

If you have exercised your basic subscription privilege in full and wish to subscribe for additional shares, in an amount up to four times the number of
shares purchased under the basic subscription privilege: 
 I apply for
                 shares x $0.33 = $                  

    (no. of new shares) (subscription price) (amount enclosed) 
 (c) PAYMENT: 
 Total Amount of Payment Enclosed = $
                 
 Method of Payment: 

All payments must be made in U.S. dollars by cashier’s or certified check drawn upon a U.S. bank payable to “Broadridge Corporate Issuer
Solutions, Inc., as Subscription Agent for Nanophase Technologies Corporation”. The Subscription Agent will not accept payment by any other means.
