 W I T N E S S E T H: 

WHEREAS, the Company, the Guarantor and the Trustee and the Collateral Trustee executed an indenture, dated as of March 3, 2017 (as
amended, supplemented or otherwise modified, the “Indenture”), providing for the issuance of the Company’s Convertible Notes due 2022 (the “Notes”); 

WHEREAS, the Company has inadvertently failed to comply with Section 10.04(B) of the Indenture which requires the Company to have in
place at all times an Acceptable Security Interest securing the Notes and other Obligations with respect thereto on Oil and Gas Properties sufficient to satisfy the Minimum Mortgage Requirement (the “Mortgage Default”); 

WHEREAS, the Company has inadvertently failed to comply with (i) Section 10.05 of the Indenture requiring the delivery of the
Reserve Report within 90 days after December 31, 2017, and (ii) Section 10.04(B) certifying compliance with the Minimum Mortgage Requirement concurrently with the delivery of the Reserve Report referenced in clause (i) above (the
“Delivery Defaults”); 
 WHEREAS, the Mortgage Default and the Delivery Defaults resulted in inaccuracies in the
Company’s certifications of no Default or Event of Default in the annual compliance certificate delivered pursuant to Section 3.06(A) of the Indenture (the “Certification Default”); 

WHEREAS, during the period following the occurrence of the Mortgage Default, the Delivery Defaults, and the Certification Default, the Company
declared and paid dividends on its Existing Preferred Stock in the months of April and May of 2018 unknowingly in breach of Section 3.11 of the Indenture, solely as the result of such other defaults, (the “Restricted Payment
Default” and together with the Mortgage Default, the Delivery Defaults, the Certification Default, and any other Default or Event of Default as a result of any failure to comply with Section 3.06 of the Indenture in relation to the
Mortgage Default, the Delivery Defaults, the Certification Default, or the Restricted Payment Default, collectively the “Existing Defaults”); 

WHEREAS, the Company has announced, pursuant to a press release issued on June 11, 2018, that it has declared a dividend on its Existing
Preferred Stock for the month of June 2018 to be payable to shareholders on July 2, 2018, and it has elected to suspend the declaration and payment of monthly cash dividends on its outstanding Existing Preferred Stock commencing July 2018 to
maintain liquidity to support its capital investment program; 
 WHEREAS, Section 8.02 of the Indenture provides that, with the consent
of the Holders of at least a majority in aggregate principal amount of the Notes then outstanding, the Company, the Guarantor, the Trustee and the Collateral Trustee may enter into an indenture supplemental to the Indenture for the purpose of
amending or supplementing the Indenture or the Notes (subject to certain exceptions); 
 WHEREAS, the Company desires and has requested the
Trustee and the Collateral Trustee to join with it and the Guarantor in entering into this Supplemental Indenture for the purpose of amending the Indenture and the Notes, as permitted by Section 8.02 of the Indenture, and to, subject to the
satisfaction of the conditions set forth in Section 5 below, waive the Existing Defaults; and

 WHEREAS, (1) the Company has received the written consent of the Holders of a majority in
aggregate principal amount of the outstanding Notes approving this Supplemental Indenture, (2) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel relating to this Supplemental Indenture, as
contemplated by Section 8.06 of the Indenture, and (3) the Company and the Guarantor have satisfied all other conditions required under Article 8 of the Indenture to enable the Company, the Guarantor and the Trustee to enter into this
Supplemental Indenture; and 
 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt
of which is hereby acknowledged, the Company, the Guarantor, the Trustee and the Collateral Trustee agree for the equal and ratable benefit of the Holders of the Notes as follows: 

1.    Defined Terms. As used in this Supplemental Indenture, terms defined in the Indenture or in the
preamble or recital to this Supplemental Indenture are used in this Supplemental Indenture as therein or herein defined. 

2.    Limited Waiver to Indenture. Subject to the satisfaction of each of the conditions set forth in
Section 5 below, on behalf of itself and each of the Holders, the Trustee waives each of the Existing Defaults. Such waiver is limited to the extent described in this Supplemental Indenture and shall not be construed to be
a consent to or a temporary or permanent waiver of any other terms, provisions, covenants, warranties or agreements contained in the Indenture or any other Indenture Document. On behalf of itself and each of the Holders, the Trustee reserves the
right to exercise any rights and remedies available to them in connection with any other present or future Defaults or Events of Default under the Indenture or any other Indenture Document. The description of the Existing Defaults in this
Supplemental Indenture is based solely upon information furnished to the Trustee, the Collateral Trustee and the Holders on or prior to the date hereof and shall not be deemed to exclude the existence of any other Defaults or Events of Default. 

3.    Amendments to the Indenture. In reliance on the representations and warranties set forth in
Section 4 below and the satisfaction of the conditions in Section 5 below, the parties to this Supplemental Indenture agree to the following amendments, in each case, effective as of the Effective
Date: 
 (a)    Section 3.11(B) of the Indenture is amended by deleting clause (ix) and replacing it with the
following: 
 (ix)    cash dividends on its Existing Preferred Stock declared for the month of June 2018
payable to shareholders on July 2, 2018 (the “June 2018 Preferred Share Dividend”) provided that at the time of and immediately after giving effect to such distribution, no Default or Event of Default has occurred and is
continuing or would result therefrom; 
 (b)    Section 3.11 of the Indenture is amended by adding new clause (C) (and
revising existing clause (C) to be new clause (D)) as follows: 
 (C)    No Dividends. For
the avoidance of doubt, the Company will not and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make cash dividends or distributions on or with respect to its Capital Stock, including for clarity, its Existing
Preferred Stock. Notwithstanding the immediately preceding sentence, subject to the terms of Section 3.11(B)(ix), the Company may make the June 2018 Preferred Share Dividend;

 3 








 
prosecute against any Releasee (as defined below) and forever waives, releases and discharges, to the fullest extent permitted by law, each Releasee from any and all claims (including, without
limitation, crossclaims, counterclaims, rights of set-off and recoupment), actions, causes of action, suits, debts, accounts, interests, liens, promises, warranties, damages and consequential damages, demands,
agreements, bonds, bills, specialties, covenants, controversies, variances, trespasses, judgments, executions, costs, expenses or claims whatsoever, that such Releasor now has or hereafter may have, of whatsoever nature and kind, whether known or
unknown, whether now existing or hereafter arising, whether arising at law or in equity (collectively, the “Claims”), against any or all of the Trustee, the Collateral Trustee and the Holders of the Notes on the date hereof and each
and all of the officers, directors, employees, agents, attorneys, advisors and other representatives of each of the foregoing (collectively, the “Releasees”). The release set forth in this Section 8(a)
includes any and all Claims, including without limitation, Claims based in whole or in part on facts, whether or not now known: (i) existing on or prior to the date of this Supplemental Indenture; (ii) as a result of this Supplemental
Indenture or any discussion or action taken or not taken by any Releasee on or before the date hereof; (iii) any discussion conducted in connection with this Supplemental Indenture; or (iv) any course of action taken by the Trustee, the
Collateral Trustee or any Holder of the Notes on the date hereof in response thereto or arising therefrom on or before the date hereof. In entering into this Supplemental Indenture, each of the Company and the Guarantors has consulted with, and has
been represented by, legal counsel. Each of the Company and the Guarantor expressly disclaims any reliance on any representations, acts or omissions by any of the Releasees and further agrees and acknowledges that the validity and effectiveness of
the releases set forth above do not depend in any way on any such representations, acts and/or omissions or the accuracy, completeness or validity thereof. 

(b)    Each of the Company and the Guarantor agrees that it shall be, jointly and severally, obligated to indemnify and
hold the Releasees harmless with respect to any and all liabilities, obligations, losses, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever incurred by the Releasees, or any of them, whether
direct, indirect or consequential, as a result of or arising from or relating to any proceeding by or on behalf of any Person, including, without limitation, the respective officers, directors, agents, trustees, creditors, partners or shareholders
of the Company, the Guarantors, or any of their respective Subsidiaries. The indemnification obligations set forth in this Section 8(b) applies to any action or proceeding, whether threatened or initiated, in respect of any

Indenture Documents, this Supplemental Indenture or any other document executed and/or delivered in connection herewith or therewith. Notwithstanding the foregoing, neither the Company nor any Guarantor shall have any obligation to indemnify or hold
harmless any Releasee with respect to liabilities to the extent they result solely from the fraud or bad faith of that Releasee as finally determined by a court of competent jurisdiction. If and to the extent that the foregoing undertaking may be
unenforceable for any reason, the Company and the Guarantors each agrees to make the maximum contribution to the payment and satisfaction of any Claim that is permissible under applicable law.

discharged by the Company or any other Guarantor pursuant to Section 8(a) of this Supplemental Indenture. If the Company, any Guarantor or any of its successors, assigns or other legal representatives violates the foregoing
covenant, the Company and the Guarantors, each for itself and its successors, assigns and legal representatives, agrees to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all attorneys’ fees and
costs incurred by any Releasee as a result of such violation.
