and as a reorganized debtor, as applicable, “UP Holdings”), (b) UP Energy Corporation, a Delaware corporation (including as a debtor-in-possession in

the signature pages hereto under the title “Debtors” (such Subsidiaries, including each as a debtor-in-possession in the Chapter 11 Cases and as a reorganized

accounts, intermediaries or nominees set forth on Schedule 1 hereto (each, a “Backstop Party” and, collectively, the “Backstop Parties”). Capitalized terms used in this Agreement are defined in
Section 14 hereof. 
 RECITALS 

WHEREAS, the Debtors, the Backstop Parties and certain other Persons have entered into a Restructuring Support Agreement, dated as of
May 14, 2020 (as amended, supplemented, amended and restated or otherwise modified from time to time, together with any schedules, exhibits and annexes thereto, the “RSA”), which provides for the restructuring of the
Debtors’ capital structure and financial obligations pursuant to a plan of reorganization in the form attached as Exhibit B to the RSA (as it may be amended, supplemented or otherwise modified from time to time, together with the Plan
Supplement, the “Plan”); 
 WHEREAS, on May 14, 2020 (the “Petition Date”), following the
execution and delivery of the RSA by the parties thereto, the Debtors commenced voluntary reorganization cases (the “Chapter 11 Cases”) under chapter 11 of title 11 of the United States Code,
11 U.S.C. §§ 101 – 1532 (as amended, the “Bankruptcy Code”), in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the “Bankruptcy Court”); 

WHEREAS, pursuant to (and subject to the terms and conditions set forth in) the Plan, the Debtors are conducting a rights offering, on
the terms set forth in the Plan, the Rights Offering Procedures and this Agreement (the “Rights Offering”), by distributing Subscription Rights to each Rights Offering Participant to purchase shares of New Common Stock on the
Effective Date, which shall consist of (a) shares of New Common Stock offered pro rata (based on the respective Pro Rata Shares of each of the Rights Offering Participants) to all Rights Offering Participants (the “Base Rights
Offering Securities”) at an aggregate purchase price of up to $42.5 million (the “Base Rights Offering Amount”), and (b) shares of New Common Stock offered pro rata (based on the respective Priority
Backstop Commitment Percentages of each of the Priority Backstop Parties) to all Priority Backstop Parties (the “Priority Rights Offering Securities” and, together with the Base Rights Offering Securities, the “Rights
Offering Securities”) at an aggregate purchase price of up to $42.5 million (the “Priority Rights Offering Amount” and, together with the Base Rights Offering Amount, the “Rights Offering
Amount”); 

  
 -1- 













 WHEREAS, the final Rights Offering Amount shall be reasonably determined by the
Debtors and must be reasonably acceptable to the Requisite Backstop Parties (but shall in no event be less than the amount set forth in the definition of “Rights Offering Amount” set forth in the Plan) and if the final Rights Offering
Amount is less than $85.0 million, then the Base Rights Offering Amount and the Priority Rights Offering Amount shall each be reduced by fifty percent (50.0%) of the difference between $85.0 million and such final Rights Offering Amount;
and 
 WHEREAS, in order to facilitate the Rights Offering, pursuant to this Agreement, and subject to the terms, conditions and
limitations set forth herein, and in reliance on the representations and warranties set forth herein, (i) each of the Backstop Parties, severally and not jointly, has agreed to provide the Debtors with the right to require such Backstop Party
to purchase, and upon exercise of such right by the Debtors, each Backstop Party has agreed to purchase from UP Energy, on the Effective Date, such Backstop Party’s Backstop Commitment Percentage of the Base Rights Offering Securities that have
not been subscribed for by the Rights Offering Participants by the Subscription Expiration Deadline (including the Unallocated Securities) (the “Unsubscribed Securities”), and (ii) each of the Priority Backstop Parties,
severally and not jointly, has agreed to provide the Debtors with the right to require such Priority Backstop Party to purchase, and upon exercise of such right by the Debtors, each Priority Backstop Party has agreed to purchase from UP Energy, on
the Effective Date, such Priority Backstop Party’s Priority Backstop Commitment Percentage of all Priority Rights Offering Securities; 

NOW, THEREFORE, in consideration of the foregoing, and the representations, warranties and covenants set forth herein, and other good
and valuable consideration, the Debtors and the Backstop Parties hereby agree as follows: 
 1. Rights Offering and Backstop
Commitments. 
 1.1 The Rights Offering. 

(a) The Debtors shall conduct and consummate the Rights Offering on the terms, subject to the conditions and in accordance with Rights
Offering Procedures set forth in Exhibit A hereto (as such procedures may be amended or supplemented from time to time with the prior written consent of the Requisite Backstop Parties, such consent not to be unreasonably withheld, delayed or
conditioned, the “Rights Offering Procedures”) and otherwise on the applicable terms and conditions set forth in this Agreement, and consistent with the Plan and the RSA. The Debtors and the Priority Backstop Parties shall cooperate
and work in good faith in determining the final Rights Offering Amount and the Debtors shall provide the Priority Backstop Parties with all materials and information reasonably requested by any of the Priority Backstop Parties or counsel to the
Backstop Parties identified in Section 12(a) hereof in connection with such determination, including the aggregate Exit RBL Lender Cash Election Amount for all Allowed First Lien RBL Claims and any investments or
expenditures that are proposed to be financed or funded (in whole or in part) with the proceeds from the Rights Offering and the sale of Backstop Securities pursuant to this Agreement. 

(b) The Company will use commercially reasonable efforts to cause the Rights Offering Subscription Agent to deliver, on behalf of the Company,
to each of the 

  
 -2- 













 
Backstop Parties, by e-mail, a funding notice (the “Backstop Funding Notice”) that sets forth (i) if there are Unsubscribed
Securities, a true and accurate calculation of the aggregate Per Share Purchase Price therefor, or (ii) if there are no Unsubscribed Securities, the fact that there are no Unsubscribed Securities (it being understood that the Backstop Base
Commitments shall terminate at the Closing). The Company will use commercially reasonable efforts to cause the Rights Offering Subscription Agent to deliver the Backstop Funding Notice to each of the Backstop Parties promptly after the later of
(A) the date on which the final Rights Offering Amount has been determined and (B) the funding deadline for Rights Offering Participants who are not Backstop Parties as set forth in the Rights Offering Procedures, but in no event shall
such delivery be made more than five (5) Business Days after such later date. 
 1.2 Backstop Commitments. 

(a) On the terms, subject to the conditions (including the entry of the Confirmation Order by the Bankruptcy Court and the Confirmation Order
becoming a Final Order) and limitations, and in reliance on the representations and warranties set forth in this Agreement, each of the Backstop Parties hereby, severally and not jointly, grants the Debtors the right to require such Backstop Party,
and upon exercise of such right by the Debtors, each Backstop Party agrees, to purchase from UP Energy, on the Effective Date, at the aggregate Per Share Purchase Price therefor, its Backstop Commitment Percentage of all Unsubscribed Securities. The
Backstop Base Commitments of the Backstop Parties are several, not joint, obligations of the Backstop Parties, such that no Backstop Party shall be liable or otherwise responsible for the Backstop Base Commitment of any other Backstop Party. The
Unsubscribed Securities that each of the Backstop Parties is required to purchase pursuant to this Section 1.2(a) are referred to herein as such Backstop Party’s “Backstop Base Commitment Securities”.

 (b) On the terms, subject to the conditions (including the entry of the Confirmation Order by the Bankruptcy Court and the Confirmation
Order becoming a Final Order) and limitations, and in reliance on the representations and warranties set forth in this Agreement, each of the Priority Backstop Parties hereby, severally and not jointly, grants the Debtors the right to require such
Priority Backstop Party, and upon exercise of such right by the Debtors, each Priority Backstop Party agrees, to purchase from UP Energy, on the Effective Date, at the aggregate Per Share Purchase Price therefor, its Priority Backstop Commitment
Percentage of all Priority Rights Offering Securities. The Backstop Priority Commitments of the Priority Backstop Parties are several, not joint, obligations of the Priority Backstop Parties, such that no Priority Backstop Party shall be liable or
otherwise responsible for the Backstop Priority Commitment of any other Priority Backstop Party. The Priority Rights Offering Securities that each of the Priority Backstop Parties is required to purchase pursuant to this
Section 1.2(b) are referred to herein as such Priority Backstop Party’s “Backstop Priority Commitment Securities”. 

(c) On or prior to the date that is three (3) Business Days prior to the anticipated Effective Date (but in no event shall such date be
less than five (5) Business Days after the date on which the Backstop Funding Notice is delivered to the Backstop Parties) (the “Deposit Deadline”), each Backstop Party shall, severally and not jointly, deposit into an account
(the “Deposit Account”) with, at the option of the Requisite Backstop Parties, the Rights Offering Subscription Agent or a bank or trust company approved by the Requisite Backstop Parties, by wire transfer of immediately available
funds, an amount equal to the aggregate Per 

  
 -3- 













 
Share Purchase Price for such Backstop Party’s Backstop Commitment Securities (such Backstop Party’s “Aggregate Purchase Price”). If the Closing has not occurred on or
prior to the later of (A) the fifth Business Day following the Deposit Deadline and (B) if a Funding Default shall have occurred, the fifth Business Day following the date on which the procedures described in
Section 1.2(b) hereof shall have been completed, any funds deposited in the Deposit Account by a Backstop Party will be returned by the Debtors to an account designated by such Backstop Party upon written request of such
Backstop Party. 
 (d) In the event that a Backstop Party defaults (a “Funding Default”) on its obligation to deposit its
Aggregate Purchase Price in the Deposit Account by the Deposit Deadline pursuant to Section 1.2(c) hereof (each such Backstop Party, a “Defaulting Backstop Party”), then each applicable Non-Defaulting Backstop Party shall have the right (the “Default Purchase Right”), but not the obligation, to elect to commit to purchase from UP Energy, at the aggregate Per Share Purchase Price
therefor, up to such Non-Defaulting Backstop Party’s Adjusted Commitment Percentage of all applicable Backstop Commitment Securities required to be purchased by the Defaulting Backstop Party pursuant to
Section 1.2(a) and/or Section 1.2(b) but which such Defaulting Backstop Party did not make the required deposit in accordance with Section 1.2(c). Within two
(2) Business Days after a Funding Default, the Company shall send a written notice (the “Default Notice”) to each applicable Non-Defaulting Backstop Party specifying (i) the
aggregate Per Share Purchase Price for all applicable Backstop Commitment Securities subject to such Funding Default (collectively, the “Default Securities”) and (ii) the maximum aggregate Per Share Purchase Price for Default
Securities such Non-Defaulting Backstop Party may elect to commit to purchase (determined in accordance with the first sentence of this Section 1.2(d)). Each applicable Non-Defaulting Backstop Party will have three (3) Business Days after receipt of the Default Notice to elect to exercise its Default Purchase Right by notifying the Company in writing of its election and
specifying the aggregate Per Share Purchase Price for Default Securities that it is committing to purchase (up to the maximum aggregate Per Share Purchase Price for Default Securities such Non-Defaulting
Backstop Party is permitted to commit to purchase pursuant to the first sentence of this Section 1.2(d)). If any Non-Defaulting Backstop Party elects to commit to purchase less than
the maximum amount of Default Securities such Non-Defaulting Backstop Party is permitted to commit to purchase pursuant to the first sentence of this Section 1.2(d) or if any Non-Defaulting Backstop Party does not elect to commit to purchase any Default Securities within the 3-Business Day period referred to in the immediately preceding sentence, then the Default Securities that such Non-Defaulting Backstop Party does not commit to purchase may be purchased by applicable Non-Defaulting Backstop Parties that exercised in full their respective Default
Purchase Rights (the right to make such purchase to be made on a pro rata basis based on the respective applicable Adjusted Commitment Percentages of such Non-Defaulting Backstop Parties, and the
process for providing commitments for such purchases to be made by utilizing substantially the same procedures set forth in the two immediately preceding sentences). To the extent the procedure described in the preceding sentence does not result in
commitments by applicable Non-Defaulting Backstop Parties for all applicable Default Securities, such procedure shall be repeated until either (A) applicable
Non-Defaulting Backstop Parties have elected to commit to purchase all of the applicable unsubscribed Default Securities or (B) applicable Non-Defaulting Backstop
Parties have ceased providing elections to commit to purchase applicable unsubscribed Default Securities and the applicable Non-Defaulting Backstop Parties have not provided elections to commit to purchase all
applicable Default Securities. 

  
 -4- 













 (e) If Non-Defaulting Backstop Parties elect to
commit to purchase all (but not less than all) Default Securities in accordance with Section 1.2(d), each Non-Defaulting Backstop Party that has elected to commit to purchase Default
Securities hereby agrees, severally and not jointly, to deposit into the Deposit Account, by wire transfer of immediately available funds, an amount equal to the aggregate Per Share Purchase Price for such Default Securities no later than two
(2) Business Days after the day that the Company has notified the Non-Defaulting Backstop Parties that Non-Defaulting Backstop Parties have elected to commit to
purchase all (but not less than all) Default Securities. If Non-Defaulting Backstop Parties do not elect to commit to purchase all Default Securities in accordance with
Section 1.2(d), then no Non-Defaulting Backstop Party shall be required to deposit in the Deposit Account any portion of the Per Share Purchase Price for the Default Securities which
such Non-Defaulting Backstop Party may have elected to commit to purchase pursuant to Section 1.2(d) unless otherwise agreed to in writing by the Requisite Backstop Parties and then
only on the terms agreed to in writing by the Requisite Backstop Parties. The Default Securities which a Backstop Party elects to purchase pursuant to Section 1.2(d), if any, together with such Backstop Party’s
Backstop Base Commitment Securities and Put Option Securities, shall be referred to herein as such Backstop Party’s “Backstop Securities”. 

(f) Fractional Backstop Securities or fractional Backstop Priority Commitment Securities shall not be issued. Anything herein to the contrary
notwithstanding, no Backstop Party shall be required or have the right to purchase or be issued any fractional Backstop Securities or fractional Backstop Priority Commitment Securities. If a Backstop Party would otherwise be required or have the
right to purchase or be issued Backstop Securities or Backstop Priority Commitment Securities that includes a fraction of a share of New Common Stock, then such number of Backstop Securities or Backstop Priority Commitment Securities shall be
rounded upward or downward to the nearest whole share of New Common Stock (with .5 of a share of New Common Stock being rounded up), and no Backstop Party shall receive any payment or other distribution in respect of any fraction of a share of New
Common Stock such Backstop Party does not receive as a result of such a rounding down. For purposes of determining whether a Backstop Party would otherwise receive a fraction of a share of New Common Stock, the total number of Rights Offering
Securities (including Backstop Priority Commitment Securities) and Backstop Securities to be issued to such Backstop Party pursuant to the Rights Offering and this Agreement shall be aggregated. 

1.3 Put Option Premium. 

(a) The Debtors and the Backstop Parties hereby acknowledge that, in consideration for the Debtors’ right to call the Backstop Base
Commitments of the Backstop Parties to purchase the Backstop Base Commitment Securities of the Backstop Parties pursuant to the terms of this Agreement, the Debtors shall be required to pay to the Backstop Parties a premium in an aggregate amount
equal to $3,187,500 (the “Put Option Base Premium”), which Put Option Base Premium shall be paid to the Backstop Parties on a pro rata basis based upon their respective Put Option Base Premium Percentages. The Debtors shall
be obligated to pay the Put Option Base Premium on the Effective Date and such payment shall be satisfied, in lieu of any cash payment, by UP Energy contributing to Ultra Resources, and Ultra Resources transferring to the Backstop Parties (or their
designees) immediately after the receipt thereof from UP Energy, an additional number of shares of New Common Stock (the “Put Option Base  

  
 -5- 













 
Securities”) equal to the quotient obtained by dividing (i) $3,187,500 by (ii) the Per Share Purchase Price, on a pro rata basis based upon their respective Put
Option Base Premium Percentages; provided, however, that if the Closing does not occur, the Debtors shall be required to pay the Put Option Base Premium to the Backstop Parties in cash to the extent provided in
Section 8(e). Notwithstanding the foregoing, (A) no Defaulting Backstop Party shall be entitled to receive any portion of the Put Option Base Premium, (B) any Non-Defaulting
Backstop Party that purchases Default Securities constituting Backstop Base Commitment Securities of a Defaulting Backstop Party shall be entitled to receive an additional portion of the Put Option Base Premium equal to the product of (x) the
amount of the Put Option Base Premium that would be payable to such Defaulting Backstop Party if such Defaulting Backstop Party had not committed a Funding Default and (y) a fraction, the numerator of which is the number of Default Securities
constituting Backstop Base Commitment Securities of such Defaulting Backstop Party which such Non-Defaulting Backstop Party purchases and the denominator of which is the total number of Default Securities
constituting Backstop Base Commitment Securities of such Defaulting Backstop Party, and (C) if a Specified Backstop Party makes an Exit Term Loan Election in respect of Backstop Base Commitment Securities (including any Default Securities that
constitute Backstop Base Commitment Securities) and the Closing occurs, then the portion of the Put Option Base Premium otherwise payable to such Specified Backstop Party in respect of such Backstop Base Commitment Securities (including any Default
Securities that constitute Backstop Base Commitment Securities) shall be payable in the form of Exit Term Loans in an aggregate principal amount equal to such portion of the Put Option Base Premium. 

(b) The Debtors and the Backstop Parties hereby acknowledge that, in consideration for the Debtors’ right to call the Backstop Priority
Commitments of the Priority Backstop Parties to purchase Backstop Priority Commitment Securities in the Rights Offering, the Debtors shall be required to pay to the Priority Backstop Parties a premium in an aggregate amount equal to $3,187,500 (the
“Put Option Priority Premium”), which Put Option Priority Premium shall be paid to the Priority Backstop Parties on a pro rata basis based upon their respective Priority Backstop Commitment Percentages. The Debtors shall be
obligated to pay the Put Option Priority Premium on the Effective Date and such payment shall be satisfied, in lieu of any cash payment, by UP Energy contributing to Ultra Resources, and Ultra Resources transferring to the Priority Backstop Parties
(or their designees) immediately after the receipt thereof from UP Energy, an additional number of shares of New Common Stock (the “Put Option Priority Securities”) equal to the quotient obtained by dividing (i) $3,187,500 by
(ii) the Per Share Purchase Price, on a pro rata basis based upon their respective Priority Backstop Commitment Percentages; provided, however, that if the Closing does not occur, the Debtors shall be required to pay the
Put Option Priority Premium to the Priority Backstop Parties in cash to the extent provided in Section 8(e). Notwithstanding the foregoing, (A) no Defaulting Backstop Party shall be entitled to receive any portion of
the Put Option Priority Premium, (B) any Non-Defaulting Backstop Party that purchases Default Securities constituting Backstop Priority Commitment Securities of a Defaulting Backstop Party shall be
entitled to receive an additional portion of the Put Option Priority Premium equal to the product of (x) the amount of the Put Option Priority Premium that would be payable to such Defaulting Backstop Party if such Defaulting Backstop Party had
not committed a Funding Default and (y) a fraction, the numerator of which is the number of Default Securities constituting Backstop Priority Commitment Securities of such Defaulting Backstop Party which such
Non-Defaulting Backstop Party purchases and the denominator of which is the total number of Default Securities 

  
 -6- 













 
constituting Backstop Priority Commitment Securities of such Defaulting Backstop Party, and (C) if a Specified Backstop Party makes an Exit Term Loan Election in respect of Backstop Priority
Commitment Securities (including any Default Securities that constitute Backstop Priority Commitment Securities) and the Closing occurs, then the portion of the Put Option Priority Premium otherwise payable to such Specified Backstop Party in
respect of such Backstop Priority Commitment Securities (including any Default Securities that constitute Backstop Priority Commitment Securities) shall be payable in the form of Exit Term Loans in an aggregate principal amount equal to such portion
of the Put Option Priority Premium. 
 (c) The Debtors hereby further acknowledge and agree that the Put Option Premium (including the
commitment premium with respect to any Exit Term Loans) (i) shall be fully earned as of the Execution Date, (ii) shall not be refundable under any circumstance or creditable against any other amount paid or to be paid in connection with
this Agreement or any of the Contemplated Transactions or otherwise, (iii) shall be paid without setoff or recoupment and shall not be subject to defense or offset on account of any claim, defense or counterclaim, (iv) except to the extent
required under the Code or other applicable Law, shall be paid free and clear of and without deduction for any and all present or future applicable Taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto
(collectively, “Deductions or Withholdings”), and to the extent of any Deductions or Withholdings, the Debtors shall pay additional amounts such that the total amount received by each Backstop Party shall equal the amount that would
have been received absent any such Deductions or Withholdings, and (v) shall be treated for U.S. federal income Tax purposes as a premium (and, as applicable, an adjustment to tax basis or adjustment to issue price) for an option to put the
Backstop Base Commitment Securities of the Backstop Parties to the Backstop Parties and the Backstop Priority Commitment Securities of the Priority Backstop Parties to the Priority Backstop Parties, as applicable, and none of the Debtors or the
Backstop Parties shall take any position or action inconsistent with such treatment and/or characterization, except as otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Internal Revenue Code
of 1986, as amended (the “Code”). 
 1.4 Exit Term Loans. Anything herein to the contrary
notwithstanding, each of the Specified Backstop Parties shall be entitled to elect (an “Exit Term Loan Election”), in lieu of purchasing Backstop Commitment Securities that it is otherwise required to purchase pursuant to this
Agreement and/or in lieu of purchasing Default Securities which such Specified Backstop Party elects to commit to purchase pursuant to this Agreement, to make Exit Term Loans to Ultra Resources on the Effective Date in an aggregate original
principal amount (excluding any original issue discount and any commitment premium) up to the aggregate Per Share Purchase Price that such Specified Backstop Party is required to pay, but not to exceed the Exit Term Loan Cap Amount for such
Specified Backstop Party. A Specified Backstop Party may make an Exit Term Loan Election by delivering written notice thereof to the Company not less than five (5) Business Days prior to the anticipated Effective Date (or, in the case an Exit Term
Loan Election is made with respect to the purchase of Default Securities, at the time such Specified Backstop Party elects to commit to purchase Default Securities pursuant to Section 1.2(d)), which notice shall specify the aggregate original
principal amount of Exit Term Loans (excluding any original issue discount and any commitment premium) that such Specified Backstop Party is electing to make. If a Specified Backstop Party makes an Exit Term Loan Election, such Specified Backstop
Party shall be required to deposit the aggregate original 

  
 -7- 













 
principal amount of the applicable Exit Term Loans (excluding any original issue discount and any commitment premium) into the Deposit Account no later than the time that such Specified Backstop
Party would have been required to deposit the Per Share Purchase Price for Backstop Commitment Securities or Default Securities that such Specified Backstop Party would be required to pay if such Specified Backstop Party did not make such Exit Term
Loan Election. Any amounts deposited by a Specified Backstop Party in the Deposit Account in respect of Exit Term Loans shall reduce, on a dollar-for-dollar basis, the
aggregate Per Share Purchase Price for Backstop Commitment Securities and Default Securities that such Specified Backstop Party would have been required to pay if such Specified Backstop Party did not make an Exit Term Loan Election, and the
Backstop Commitment Securities and Default Securities that a Specified Backstop Party would have otherwise received if such Specified Backstop Party had paid such aggregate Per Share Purchase Price will not be issued. Any reference to the term
“Rights Offering Securities”, “Backstop Securities”, “Backstop Base Commitment Securities”, “Backstop Priority Commitment Securities”, “Put Option Securities” or “Default Securities” used
in this Agreement shall be deemed to include Exit Term Loans and/or Exit Warrants to the extent any Specified Backstop Party makes an Exit Term Loan Election and such inclusion is applicable.

further, that if a Specified Backstop Party makes an Exit Term Loan Election, then UP Energy and Ultra Resources shall deliver to such Specified Backstop Party at the Closing, at the request of such Specified Backstop Party at least one

 (c) Anything
in this Agreement to the contrary notwithstanding (but without limiting the provisions of Section 13.1 hereof), any Backstop Party, in its sole discretion, may designate that some or all of the Backstop Securities and/or

Commitment Securities that should be issued or delivered to each such Affiliate (or the applicable aggregate Per Share Purchase Price and/or portion of the Put Option Premium, as applicable, for such Backstop Securities and/or Backstop Priority
Commitment Securities), and (iii) contain a certification from each such Affiliate of the accuracy of the representations and warranties made by each Backstop Party in Section 4 hereof as applied to such Affiliate. Any

Bankruptcy Court Order. All Backstop Expenses of a Backstop Party shall be paid to such Backstop Party (or its designee) by wire transfer of immediately available funds to the account(s) specified by such Backstop Party. The Backstop Expenses shall
constitute allowed administrative expenses against the Debtors’ estates under the Bankruptcy Code. The terms set forth in this Section 2.2 shall survive termination of this Agreement and shall remain in full force and
effect regardless of whether the transactions contemplated by this Agreement or any of the other Contemplated Transactions are consummated. The obligations set forth in this Section 2.2 are in addition to, and do not limit,

Rights”) as such Debtor IP Rights are used in the business of any Debtor, except where the failure to own or possess such rights to (or have adequate licenses related to) any such IP Rights would not, individually or in the aggregate,

has not been any material malfunction with respect to any of the Debtor IT Systems that has caused material disruption to any Debtor’s businesses or operations in the past three (3) years that has not been remedied or replaced in all

of any of the Debtors therein or thereunder, except to the extent that any such non-compliance, revocation or termination would not, individually or in the aggregate, reasonably be expected to be adverse in
any material respect to the Debtors, taken as a whole. No Debtor has received notice of any revocation, suspension or modification of any of the Licenses and Permits, has any reason to believe that any of the Licenses and Permits will be revoked or

Debtors.

 -37- 













 
Transactions shall have been entered, issued, rendered or made, nor shall any Proceeding seeking any of the foregoing be commenced, pending or threatened; nor shall there be any Law promulgated,
enacted, entered, enforced or deemed applicable to the Backstop Parties or the Debtors which makes the consummation of any of the transactions contemplated by this Agreement or any of the other Contemplated Transactions (including each of the
Specified Issuances) illegal or void.

warranties, covenants or other obligations 

  
 -38- 













 
contained in this Agreement (including covenants incorporated into this Agreement by reference), or any representation or warranty of any of the Debtors in this Agreement shall have become untrue
(determined as if the Debtors made their respective representations and warranties at all times on and after the Execution Date and prior to the date this Agreement is terminated), and (B) any such breach, failure to perform or occurrence
referred to in clause (A) above (x) would result in a failure of a condition set forth in Section 7.1 and (y) is not curable or able to be performed by the Drop-Dead Date, or, if curable or able to be
performed by the Drop-Dead Date, is not cured or performed within seven (7) Business Days after written notice of such breach, failure or occurrence is given to the Debtors by the Requisite Backstop Parties (it being understood and agreed that
the failure by the Debtors to comply with any of the covenants set forth in Section 5.7 will result in a failure of a condition set forth in Section 7.1 and shall not be subject to cure); 

(ii) if any of the conditions set forth in Section 7.1 hereof become incapable of fulfillment prior

Non-Defaulting Backstop Parties do not elect to commit to purchase all of the Default Securities after the process for exercising Default Purchase Rights has been exhausted in accordance with
Section 1.2(d); 
 (vi) if any Law or Order has been enacted or entered by any Governmental Body

 -39- 













 (c) This Agreement (including the Backstop Commitments contemplated hereby) may be
terminated at any time by the Debtors effective immediately upon the Debtors’ giving of written notice of termination to the Backstop Parties: 

(i) if (A) any of the Backstop Parties shall have breached or failed to perform any of their respective representations,
warranties, covenants or other obligations contained in this Agreement, or any representation or warranty of any of the Backstop Parties in this Agreement shall have become untrue (determined as if the Backstop Parties made their respective
representations and warranties at all times on and after the Execution Date and prior to the date this Agreement is terminated), and (B) any such breach, failure to perform or occurrence referred to in clause (A) above (x) would
result in a failure of a condition set forth in Section 7.2 and (y) is not curable or able to be performed by the Drop-Dead Date, or, if curable or able to be performed by the Drop-Dead Date, is not cured or performed
within seven (7) Business Days after the Debtors provide the Requisite Backstop Parties of notice of such breach, failure or occurrence; provided, however, that if a Funding Default shall occur, the Debtors shall not be permitted

purchase all of the Default Securities after the process for exercising Default Purchase Rights has been exhausted in accordance with Section 1.2(d); 

(ii) if a Funding Default shall occur and Non-Defaulting Backstop Parties do not elect
to commit to purchase all of the Default Securities after the process for exercising Default Purchase Rights has been exhausted in accordance with Section 1.2(d); 

(iii) if any Law or Order has been enacted or entered by any Governmental Body that operates to materially prevent, restrict or
alter the implementation of the Plan, the Rights Offering or any of the Contemplated Transactions; or 
 (iv) if the Closing

 (d) This Agreement (including the Backstop Commitments contemplated hereby) may be

applicable) by wire transfer of immediately available funds to an account designated by each Backstop Party; provided, however, that the Put Option Premium shall not be payable in the event of (i) a termination of this Agreement
by the Debtors pursuant to Section 8(c)(i) or Section 8(c)(ii) hereof, (ii) a termination of this Agreement pursuant to Section 8(a)(ii) hereof as a
result of a termination of the RSA by the Debtors pursuant to 13.04(b) of the RSA or (iii) a termination of this Agreement pursuant to Section 8(b)(vii) or Section 8(c)(iv) hereof if the

 -40- 













 (f) In the event of a termination of this Agreement in accordance with this
Section 8 at a time after all or any portion of the Aggregate Purchase Price for Backstop Commitment Securities or all or any portion of the aggregate Per Share Purchase Price for Default Securities that any of the Backstop
Parties elects to commit to purchase has been deposited into the Deposit Account by any of the Backstop Parties, the Backstop Parties that have deposited such Aggregate Purchase Price (or portion thereof) or such aggregate Per Share Purchase Price
(or portion thereof) shall be entitled to the return of such amount. In such a case, the Backstop Parties and the Debtors hereby agree to execute and deliver to the Rights Offering Subscription Agent, promptly after the effective date of any such
termination (but in any event no later than two (2) Business Days after any such effective date), a letter instructing the Rights Offering Subscription Agent to pay to each applicable Backstop Party, by wire transfer of immediately available
funds to an account designated by such Backstop Party, the amount of Aggregate Purchase Price and/or aggregate Per Share Purchase Price for Default Securities that such Backstop Party is entitled to receive pursuant to this
Section 8(f). 
 (g) In the event of a termination of this Agreement in accordance with this
Section 8, the provisions of this Agreement shall immediately become void and of no further force or effect (other than Sections 2.2, 8, 9, 11, 12 and 13 hereof (and any
defined terms used in any such Sections (but solely to the extent used in any such Sections)), and other than in respect of any liability of any party for any breach of this Agreement prior to such termination, which shall in each case expressly
survive any such termination). 
 (h) Each Debtor hereby acknowledges and agrees and shall not dispute that the giving of notice of
termination by the Requisite Backstop Parties pursuant to this Agreement shall not be a violation of the automatic stay of section 362 of the Bankruptcy Code (and each Debtor hereby waives, to the greatest extent possible, the applicability of the
automatic stay to the giving of such notice). 
 9. Indemnification. 

(a) Whether or not the transactions contemplated by this Agreement or any of the other Contemplated Transactions are consummated, the Debtors
hereby agree, jointly and severally, to indemnify and hold harmless (i) each of the Backstop Parties, (ii) each of the Affiliates of each of the Backstop Parties, and (iii) each of the stockholders, equity holders, members, partners,
managers, officers, directors, employees, attorneys, accountants, financial advisors, consultants, agents, advisors and controlling persons of each of the Backstop Parties and each of the Affiliates of each of the Backstop Parties (each, in such
capacity, an “Indemnified Party”) from and against any and all losses, claims, damages, liabilities, costs and expenses (including reasonable attorneys’ fees), interest, penalties, judgments and settlements (excluding Taxes of
the Backstop Parties except to the extent otherwise provided for in this Agreement) arising out of or related to a third party claim that are imposed on, sustained, incurred or suffered by, or asserted against, any Indemnified Party as a result of,
arising out of, related to or in connection with, directly or indirectly, this Agreement, the Backstop Commitments, the Backstop Securities, the Backstop Priority Commitment Securities, the Exit 

  
 -41- 













 
Term Loans, the Exit Warrants, the Rights Offering, any of the Definitive Documents (including the Plan), the solicitation of the Plan, the Chapter 11 Cases or the transactions contemplated
hereby or thereby or any of the other Contemplated Transactions, or any claim, litigation, investigation or other Proceeding relating to or arising out of any of the foregoing, regardless of whether any such Indemnified Party is a party thereto, and
to pay and/or reimburse each such Indemnified Party for the reasonable and documented legal or other out-of-pocket costs and expenses as they are incurred in connection
with investigating, monitoring, responding to or defending any of the foregoing (collectively, “Losses”); provided, that the foregoing indemnification will not, as to any Indemnified Party, apply to Losses that are determined
by a final, non-appealable decision by a court of competent jurisdiction to have resulted solely from any act by such Indemnified Party that constitutes fraud, gross negligence or willful misconduct. If for
any reason the foregoing indemnification is unavailable to any Indemnified Party or insufficient to hold it harmless, then the Debtors shall contribute to the amount paid or payable by such Indemnified Party as a result of such Loss in such
proportion as is appropriate to reflect not only the relative benefits received by the Debtors on the one hand and such Indemnified Party on the other hand but also the relative fault of the Debtors, on the one hand, and such Indemnified Party, on
the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Debtors on the one hand and all Indemnified Parties on the other hand shall be deemed to be in the same proportion as
(i) the total value received or proposed to be received by the Debtors pursuant to the sale of the maximum number of Backstop Securities and Backstop Priority Commitment Securities to the Backstop Parties pursuant to this Agreement (assuming a
Rights Offering Amount equal to $85.0 million) bears to (ii) the Put Option Premium. The Debtors also agree that no Indemnified Party shall have any liability based on its exclusive or contributory negligence or otherwise to the Debtors, any
Person asserting claims on behalf of or in right of the Debtors, or any other Person in connection with or as a result of this Agreement, the Backstop Commitments, the Backstop Securities, the Backstop Priority Commitment Securities, the Exit Term
Loans, the Exit Warrants, the Rights Offering, any of the Definitive Documents (including the Plan), the solicitation of the Plan, the Chapter 11 Cases, or the transactions contemplated hereby or thereby or any of the other Contemplated
Transactions, except as to any Indemnified Party to the extent that any Losses incurred by the Debtors resulted solely from the fraud, gross negligence or willful misconduct of such Indemnified Party, as determined by a final, non-appealable decision by a court of competent jurisdiction. The terms set forth in this Section 9 shall survive termination of this Agreement and shall remain in full force and effect
regardless of whether the transactions contemplated by this Agreement or any of the other Contemplated Transactions are consummated. The indemnity, contribution and reimbursement obligations of the Debtors under this
Section 9 are in addition to, and do not limit, the Debtors’ obligations under Sections 2.2 and 8. 

(b) Promptly after receipt by an Indemnified Party of notice of the commencement of any claim, litigation, investigation or other Proceeding
with respect to which such Indemnified Party may be entitled to indemnification hereunder (“Actions”), such Indemnified Party will, if a claim is to be made hereunder against the Debtors in respect thereof, notify the Debtors in
writing of the commencement thereof; provided, that (i) the omission to so notify the Debtors will not relieve the Debtors from any liability that they may have hereunder except to the extent (and solely to the extent) they have been
actually and materially prejudiced by such failure and (ii) the omission to so notify the Debtors will not relieve the Debtors from 

  
 -42- 













 
any liability that they may have to an Indemnified Party otherwise than on account of this Section 9. In case any such Actions are brought against any Indemnified Party
and such Indemnified Party notifies the Debtors of the commencement thereof, if the Debtors commit in writing to fully indemnify and hold harmless the Indemnified Party with respect to such Actions, without regard to whether the Effective Date
occurs, the Debtors will be entitled to participate in such Actions, and, to the extent that the Debtors elect by written notice delivered to such Indemnified Party, to assume the defense thereof, with counsel satisfactory to such Indemnified Party;
provided, that if the defendants in any such Actions include both such Indemnified Party and the Debtors and such Indemnified Party shall have concluded that there may be legal defenses available to it that are different from or additional to
those available to the Debtors, such Indemnified Party shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such Actions on behalf of such Indemnified Party. Following the date
of receipt by an Indemnified Party of such indemnification commitment from the Debtors and notice from the Debtors of their election to assume the defense of such Actions and approval by such Indemnified Party of counsel, the Debtors shall not be
liable to such Indemnified Party for expenses incurred by such Indemnified Party in connection with the defense thereof after such date (other than reasonable costs of investigation and monitoring) unless (w) such Indemnified Party shall have
employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence, (x) the Debtors shall not have employed counsel satisfactory to such Indemnified Party to
represent such Indemnified Party at the Debtors’ expense within a reasonable time after notice of commencement of the Actions, (y) after the Debtors assume the defense of such Actions, such Indemnified Party determines that the Debtors are
failing to diligently defend against such Actions in good faith or (z) any of the Debtors shall have authorized in writing the employment of counsel for such Indemnified Party and agreed to be liable for such expenses. 

(c) The Debtors shall not, without the prior written consent of an Indemnified Party, effect any settlement, compromise or other resolution of
any pending or threatened Actions in respect of which indemnity has been sought hereunder by such Indemnified Party unless such settlement, compromise or other resolution (i) includes an unconditional release of such Indemnified Party in form
and substance satisfactory to such Indemnified Party from all liability on the claims that are the subject matter of such Actions and (ii) does not include any statement as to or any admission of fault, culpability or a failure to act by or on
behalf of any Indemnified Party. 
 10. Survival. The representations, warranties, covenants and agreements made in
this Agreement shall not survive the Closing except for covenants and agreements made in this Agreement that by their terms are to be satisfied or complied with after the Closing, which covenants and agreements shall survive until fully satisfied or
complied with in accordance with their terms. 
 11. Amendments and Waivers. Any term of this Agreement may be amended
or modified and the compliance with any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only if such amendment, modification or waiver is signed, in the case of an
amendment or modification, by the Requisite Backstop Parties and the Debtors, or in the case of a waiver, by the Requisite Backstop Parties (if 

  
 -43- 













 
compliance by the Debtors is being waived) or by the Requisite Backstop Parties and the Debtors (if compliance by any of the Backstop Parties is being waived); provided, however,
that (a) Schedule 1, Schedule 2 and Schedule 3 hereto may be updated in accordance with the terms of Section 13.1 hereof, (b) any amendment or modification to this Agreement that would have
the effect of changing the Backstop Commitment Percentage (including both the Tier 1 Backstop Commitment Percentage and the Tier 2 Backstop Commitment Percentage), the Priority Backstop Commitment Percentage or the Exit Term Loan Cap Amount of any
Backstop Party shall require the prior written consent of such Backstop Party, (c) any amendment or modification to the definition of “Aggregate Purchase Price” or the allocation of the Put Option Premium among the Backstop Parties as
set forth in Section 1.3 shall (in any such case) require the prior written consent of each Backstop Party adversely affected thereby, (d) any amendment or modification to the definition of “Specified Backstop
Party” shall require the prior written consent of each Specified Backstop Party adversely affected thereby, (e) any amendment or modification to Section 1.4 hereof and the definitions of “Exit Term
Loans” and “Exit Warrants” shall require the prior written consent of the Requisite Backstop Parties and the Specified Backstop Parties whose aggregate Exit Term Loan Cap Amount is more than 50.0% of the aggregate Exit Term Loan Cap
Amount for all Specified Backstop Parties, (f) any amendment or modification to the definition of “Priority Backstop Party” shall require the prior written consent of each Priority Backstop Party adversely affected thereby, and
(g) any amendment, modification or waiver to this Agreement that would adversely affect any of the rights or obligations (as applicable) of any Backstop Party set forth in this Agreement in a manner that is different or disproportionate in any
material respect from the effect on the comparable rights or obligations (as applicable) of the Requisite Backstop Parties set forth in this Agreement (other than in proportion to the amount of the Backstop Commitments held by each of the Backstop
Parties) shall also require the written consent of such affected Backstop Party (it being understood that in determining whether consent of any Backstop Party is required pursuant to this clause (g), no personal
circumstances of such Backstop Party shall be considered). No delay on the part of any party in exercising any right, power or privilege pursuant to this Agreement will operate as a waiver thereof, nor will any waiver on the part of any party of any
right, power or privilege pursuant to this Agreement, or any single or partial exercise of any right, power or privilege pursuant to this Agreement, preclude any other or further exercise thereof or the exercise of any other right, power or
privilege pursuant to this Agreement. The rights and remedies provided pursuant to this Agreement are cumulative and are not exclusive of any rights or remedies which any party otherwise may have at Law or in equity. 

12. Notices, etc.. Except as otherwise expressly provided in this Agreement, all notices, requests,
demands, document deliveries and other communications under this Agreement shall be in writing and shall be deemed to have been duly given, provided, made or received (a) when sent by electronic mail
(“e-mail”), (b) when delivered personally, (c) one (1) Business Day after deposit with an overnight courier service, or (d) three (3) Business Days after mailed by certified or

Miscellaneous. 
 13.1 Assignments. This Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned by any of the parties (whether by operation of Law or
otherwise) without the prior written consent of the Debtors and the Requisite Backstop Parties. Notwithstanding the immediately preceding sentence, any Backstop Party’s rights, obligations or interests hereunder may be freely assigned,
delegated or transferred, in whole or in part, by such Backstop Party to (a) any other 

  
 -45- 













 
Backstop Party, (b) any Affiliate of a Backstop Party, or (c) any other Person not referred to in clause (a) or clause (b) above so long as such Person is
approved in writing by the Requisite Backstop Parties prior to such assignment, delegation or transfer (for purposes of this clause (c), the Backstop Party proposing to make such assignment, delegation or transfer, and all of its Affiliates,
shall be deemed to be Defaulting Backstop Parties for purposes of determining whether the definition of “Requisite Backstop Parties” has been satisfied); provided, that (x) any such assignee assumes the obligations of the
assigning Backstop Party hereunder that are being assigned to such assignee and agrees in writing prior to such assignment to be bound by the terms hereof in the same manner as the assigning Backstop Party (which writing shall contain, if the
assignee is not already a Backstop Party, a certification from the assignee as to the accuracy of the representations and warranties made by each Backstop Party in Section 4 hereof as applied to such assignee), (y) any
assignee of a Backstop Commitment must be an Accredited Investor, and (z) the right to purchase Rights Offering Securities (including Priority Rights Offering Securities) are only assignable as set forth in the Rights Offering Procedures.
Following any assignment described in the immediately preceding sentence, Schedule 1 and, if applicable, Schedule 2 and/or Schedule 3 hereto shall be updated by the Debtors (in consultation with the assigning Backstop Party and
the assignee) solely to reflect (i)(A) the name and address of the applicable assignee or assignees, and (B) the Backstop Commitment Percentage (including both the Tier 1 Backstop Commitment Percentage and the Tier 2 Backstop Commitment
Percentage) and, if applicable, the Priority Backstop Commitment Percentage and Exit Term Loan Cap Amount that shall apply to such assignee or assignees, in each case as specified by the assigning Backstop Party and the assignee or assignees, and
(ii) any changes to the Backstop Commitment Percentage (including both the Tier 1 Backstop Commitment Percentage and the Tier 2 Backstop Commitment Percentage) and, if applicable, the Priority Backstop Commitment Percentage and the Exit Term
Loan Cap Amount applicable to the assigning Backstop Party, in each case as specified by the assigning Backstop Party and the assignee or assignees (it being understood and agreed that updates to Schedule 1, Schedule 2 and/or
Schedule 3 hereto shall not result in an overall change to the aggregate Backstop Commitment Percentages, Priority Backstop Commitment Percentages and Exit Term Loan Cap Amounts for all Backstop Parties). Any update to Schedule 1,
Schedule 2 and/or Schedule 3 hereto described in the immediately preceding sentence shall not be deemed an amendment to this Agreement. Notwithstanding the foregoing or any other provisions herein, unless otherwise agreed in any
instance by the Debtors and the Requisite Backstop Parties (for purposes of this sentence, the Backstop Party making such assignment, and all of its Affiliates, shall be deemed to be Defaulting Backstop Parties for purposes of determining whether
the definition of “Requisite Backstop Parties” has been satisfied), no assignment of obligations by a Backstop Party to an Affiliate of such Backstop Party will relieve the assigning Backstop Party of its obligations hereunder if any such
Affiliate assignee fails to perform such obligations. 
 13.2 Severability. If any provision of this Agreement, or the
application of any such provision to any Person or circumstance, shall be held invalid or unenforceable in whole or in part, such invalidity or unenforceability shall attach only to such provision or part thereof and the remaining part of such
provision and this Agreement shall continue in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon any such determination
of invalidity, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a reasonably acceptable manner in order that the transactions contemplated hereby
are consummated as originally contemplated to the greatest extent possible. 

  
 -46- 













 13.3 Entire Agreement. Except as expressly set forth herein, this
Agreement and the RSA constitute the entire understanding among the parties hereto with respect to the subject matter hereof and replace and supersede all prior agreements and understandings, both written and oral, among the parties hereto with
respect to the subject matter hereof; provided, however, that this Agreement shall supersede and entirely replace the terms, covenants and agreements set forth in Section 6 of the RSA. 

13.4 Counterparts. This Agreement may be executed in any number of counterparts, each of which will be an original, and
all of which, when taken together, will constitute one agreement. Delivery of an executed counterpart of this Agreement by facsimile or portable document format (PDF) will be effective as delivery of a manually executed counterpart of this
Agreement. 
 13.5 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICTS OF LAW PRINCIPLES THEREOF EXCEPT SECTIONS 5-1401 AND 5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK.

 13.6 Submission to Jurisdiction. Each party to this Agreement hereby (a) consents to submit itself to the
personal jurisdiction of the Bankruptcy Court, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from the Bankruptcy Court, including a motion to dismiss on the grounds of
forum non conveniens, and (c) agrees that it will not bring any action arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the Bankruptcy Court; provided that if
the Bankruptcy Court lacks jurisdiction, the parties consent and agree that such actions or disputes shall be brought in the federal court of the Southern District of New York or any state court located in New York County, State of New York. 

13.7 Waiver of Trial by Jury; Waiver of Certain Damages. EACH PARTY HERETO HEREBY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT
TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS AGREEMENT, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY SUCH RIGHTS OR OBLIGATIONS. Except as prohibited by Law, the Debtors hereby waive any right which they
may have to claim or recover in any action or claim referred to in the immediately preceding sentence any special, exemplary, punitive or consequential damages or any damages other than, or in addition to, actual damages. Each of the Debtors (a)
certifies that none of the Backstop Parties nor any Representative of any of the Backstop Parties has represented, expressly or otherwise, that the Backstop Parties would not, in the event of litigation, seek to enforce the foregoing waivers and (b)
acknowledges that, in entering into this Agreement, the Backstop Parties are relying upon, among other things, the waivers and certifications contained in this Section 13.7. 

  
 -47- 













 13.8 Further Assurances. From time to time after the Execution Date,
the parties hereto will execute, acknowledge and deliver to the other parties hereto such other documents, instruments and certificates, and will take such other actions, as any other party hereto may reasonably request in order to consummate the
transactions contemplated by this Agreement. 
 13.9 Specific Performance. The Debtors and the Backstop Parties
acknowledge and agree that (a) irreparable damage would occur in the event that any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached, and (b) remedies at Law would not
be adequate to compensate the non-breaching party. Accordingly, the Debtors and the Backstop Parties agree that each of them shall have the right, in addition to any other rights and remedies existing in its
favor, to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce its rights and obligations hereunder not only by an action or actions for damages but also by an action or actions for specific
performance, injunctive and/or other equitable relief. The right to equitable relief, including specific performance or injunctive relief, shall exist notwithstanding, and shall not be limited by, any other provision of this Agreement. Each of the
Debtors and each of the Backstop Parties hereby waives any defense that a remedy at Law is adequate and any requirement to post bond or other security in connection with actions instituted for injunctive relief, specific performance or other
equitable remedies.
