THE BACKSTOP COMMITMENT

Backstop Commitment.

New Common Shares. The Rights Offering will be made, and the New Common Shares will be issued and sold, in reliance on the exemption from registration provided by section 4(a)(2) and Regulation D of the Securities Act or another available exemption from registration under the Securities Act, and, in each case, the Disclosure Statement, Confirmation Order and Plan shall include a statement to such effect.

The Rights Offering and the Backstop Purchase Obligation.

On and subject to the terms and conditions hereof and the Rights Offering Procedures, each Backstop Party agrees, severally and not jointly, not to (i) fully exercise all, and not to permit any of its controlled Affiliates to exercise, any Subscription Rights that are properly issued to it and its Designated Affiliates pursuant to the Rights Offering, (ii) duly purchase at the Purchase Price all First Lien Term Loans and New Common Shares issuable to it pursuant to such exercise, and (iii) complete, duly execute, and submit a subscription exercise form and any other documentation required pursuant to the Rights Offering Procedures and the Plan in connection therewith.

On and subject to the terms and conditions hereof, each Backstop Party agrees, severally and not jointly, to purchase, at the Purchase Price, (i) Remaining First Lien Term Loans in an aggregate principal amount

Notwithstanding anything to the contrary in this Agreement, in no event shall any Backstop Party be required to purchase First Lien Term Loans, New Common Shares, Remaining First Lien Term Loans, and Remaining New Common Shares for an aggregate Purchase Price in excess of such Backstop Party’s Backstop Commitment.

Backstop Notice. On or before the fifth (5^th) Business Day after the Offering Deadline, the Company shall cause the Subscription Agent to notify each Backstop Party in writing (the “Backstop Notice”) as to: (a) the Remaining First Lien Term Loans and Remaining New Common Shares; (b) the Purchase Price required to be paid pursuant to such Backstop Party’s consequent Backstop Purchase Obligation; (c) such Backstop Party’s Subscription Amount and Backstop Amount (collectively, such Backstop Party’s “Funding Amount”); and (dc) the account information (including wiring instructions) for the account to which such Backstop Party shall deliver and pay the Funding Amount, which account may be an escrow account and the Funding Amount (the “Subscription Account”).

Escrow; Closing.

Escrow. No later than two (2) Business Days prior to the Effective Date (such date, the “Subscription Funding Date”), each Backstop Party shall deliver and pay its Funding Amount by wire transfer of immediately available funds in U.S. dollars into the Subscription Account in satisfaction of such Backstop Party’s purchase obligations under this Agreement.

Closing. (a) Subject to Article VI, the closing of the transactions contemplated hereby (the “Closing”) shall take places at the offices of Porter Hedges LLP, 1000 Main Street, 36^th Floor, Houston, Texas 77002, at 5:00 p.m., New York City time, on the Effective Date contemporaneously with the substantial consummation of the Plan.

At the Closing, the funds held in the Subscription Account shall be released to the Company.

At the Closing, issuance of the applicable portion of the Remaining First Lien Term Loans and Remaining New Common Shares will be made by the reorganized Company to each Backstop Party against payment of such Backstop Party’s Funding Amount, in satisfaction of such Backstop Party’s purchase obligations pursuant to the Rights Offering and this Agreement.

Premium. Subject to Section 2.4, the Company Parties, jointly and severally, hereby agree to pay each Backstop Party its pro rata share (based on such Backstop

Certain Tax Matters. All Parties hereto agree to treat the transactions contemplated by this Agreement as follows for U.S. federal income tax purposes: (a) the Backstop Purchase Obligation shall be treated as a put option; (b) the Backstop Commitment Premium herein shall be treated as remuneration to the Backstop Parties for agreeing to enter into such put option; (c) the calculation by the Company Parties or their agents regarding the amount of “original issue discount” within the meaning of Section 1273(a) of the Code, if any, with respect to the First Lien Term Loans, shall be as set forth by the Company Parties or their agents in accordance with applicable U.S. tax Law, Treasury regulations, and other applicable guidance, and will be available, after preparation, to the Backstop Party with respect to the First Lien Term Loans held by such Backstop Party, for any accrual period in which such Backstop Party held such First Lien Term Loans, promptly upon request, and (d) no Party shall take any position or action inconsistent with such treatment and/or characterization, except, in each case, to the extent otherwise required by applicable Law. This Section 2.2.4 is not an admission by any Backstop Party that it is subject to United States taxation.

Withholding. The Backstop Commitment Premium shall be issued free and clear of and without deduction for any and all taxes, levies, imposts, deductions, charges or withholdings (except for any taxes, levies, imposts, deductions, charges or withholdings arising as a result of a Backstop Party’s failure to provide an IRS Form W-9 or appropriate IRS Form W-8, as applicable, upon reasonable request of the Company or the Subscription Agent), in each case applicable to the issuance thereof, and all liabilities with respect thereto (with appropriate gross up for withholding taxes as required by applicable Law).

Expense Reimbursement.

The Company Parties, jointly and severally, agree to pay or reimburse, to the extent not otherwise paid pursuant to the RSA or in connection with the Chapter 11 Cases or another order of the Bankruptcy Court, all reasonable and documented accrued and unpaid fees, costs and out-of-pocket expenses of the Backstop Parties’ Professionals, incurred in connection with this Agreement, the RSA, and these Chapter 11 Cases, whether prior to, on, or after the date hereof through the Effective Date (the “Expense Reimbursement”). The Company Parties shall pay the Expense Reimbursement on the Effective Date with respect to all such reasonable and documented fees, costs, and out-of-pocket expenses for which invoices or receipts are forwarded to the Company by the Backstop Parties at least one (1) Business Day prior to the Effective Date. Subject to any procedures for the payment of such fees, costs, and out-of-pocket expenses required by any cash collateral order, the Company Parties shall also pay the Expense Reimbursement on a regular, continuing basis when due in accordance with any applicable engagement letters or

Funding Default.

Upon the occurrence of a Funding Default, the Backstop Parties (other than any Defaulting Backstop Party) shall have the right, but not the obligation, within five (5) Business Days after receipt of written notice from the Company to all Backstop Parties (other than any Defaulting Backstop Party) of such Funding Default, which notice shall be given promptly following the occurrence of such Funding Default and to all Backstop Parties (other than any Defaulting Backstop Party) substantially concurrently (such five (5) Business Day period, the “Replacement Period”), to elect, by written notice to the Company, to purchase all or any portion of the Remaining New Common Shares and Remaining First Lien Term Loans not purchased as a result of such Funding Default (any such purchase, a “Replacement Purchase”) on the terms and subject to the conditions set forth in this Agreement and in such amounts as may be agreed upon by all of the Backstop Parties (other than any Defaulting Backstop Party) that elect to purchase all or any portion of the Remaining New Common Shares and Remaining First Lien Term Loans attributable to such Defaulting Backstop Party, or, if no such agreement is reached by the date upon which the Replacement Period expires, based upon each such electing Backstop Party’s Backstop Percentage of the aggregate number of Remaining New Common Shares and Remaining First Lien Term Loans that have not been purchased as a result of such Funding Default (such Backstop Parties, the “Replacing Backstop Parties”). The purchase price paid by any Replacing Backstop Party in connection with a Replacement Purchase shall be equal to the applicable Purchase Price. Within five (5) Business Days from delivery of written notice of a Funding Default, electing Backstop Parties will fund the Subscription Account with the additional Purchase Price with respect to the Replacement Purchase.

If a Backstop Party is a Defaulting Backstop Party, it shall not be entitled to any Backstop Commitment Premium hereunder and the aggregate Backstop Commitment Premium shall be reduced ratably upon a Funding Default based on the Defaulting Backstop Party’s Backstop Percentage; provided, that if a Replacement Purchase sufficient to cure all or a portion of the Funding Default occurs, the Backstop Commitment Premium shall only be ratably reduced to the extent of the uncured Funding Default, and such amount that would have otherwise been reduced shall be paid to the Replacing Backstop Parties, as applicable.

Other than as set forth in Section 2.4.1, nothing in this Agreement shall require any Backstop Party to purchase more Remaining First Lien Term Loans and Remaining New Common Shares than its Backstop Purchase Obligation.

Notwithstanding anything to the contrary set forth in Section 8.12 but subject to Section 8.14, no provision of this Agreement shall relieve any Defaulting Backstop Party from liability hereunder, or limit the availability of the remedies set forth in Section 8.15 or otherwise available to the non-defaulting parties hereto, in connection with any such Backstop Party’s Funding Default.

Waivers and Amendments. This Agreement may be amended, modified or superseded, and the terms and conditions of this Agreement may be waived, only by a written instrument signed by the Company and the Backstop Parties representing a majority of the aggregate Backstop Commitment of all Backstop Parties (the “Required Backstop Parties”). 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. No waiver on the part of any Party of any right, power or privilege pursuant to this Agreement, nor any single or partial exercise of any right, power or privilege pursuant to this Agreement, shall 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

Governing Law; Jurisdiction; Venue; Process. This Agreement, the construction of its terms, the interpretation of the rights and duties arising hereunder, and actions, causes of action or claims of any kind (whether at law, in equity, in contract, in tort, or otherwise) that may be based upon, arise out of, or relate to this Agreement, or the negotiation, execution or performance of this Agreement, shall be governed by and construed in accordance with the Laws of the State of New York, without giving effect to any conflict of laws principles that would require the application of the Law of any other jurisdiction. Each Party hereby irrevocably submits, for itself and its property, to the exclusive jurisdiction of the courts of the State of New York located in the Borough of Manhattan, for purposes of all legal proceedings arising out of or relating to this Agreement or the transactions contemplated hereby. Each Party irrevocably waives, to the fullest extent permitted by Law, any objection which it may now or hereafter have to the laying of venue of any such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. Notwithstanding the foregoing, during the pendency of the Chapter 11 Cases, all proceedings contemplated by this Section 8.6 shall be brought in the Bankruptcy Court.

Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. All such counterparts will be deemed an original, will be construed together and will constitute one and the same instrument.

Headings. The headings in this Agreement are for reference purposes only and will not in any way affect the meaning or interpretation of this Agreement.

at the Company’s election, by written notice to the Backstop Parties, if the Company determines in good faith, based on the advice of counsel, that proceeding with the Rights Offering and the Restructuring would be inconsistent with the exercise of the fiduciary duties under applicable law of the board of directors or analogous governing body of the Company; provided, however, that the Company provides written notice of such determination to the Backstop Parties within one (1) Business Day after the date of such determination; or

at the Required Backstop Parties’ election, by written notice to the Company, in the event (i) of a material breach by any Company Party of this Agreement, if such breach has not been waived by the Required Backstop Parties or cured within five (5) Business Days after the delivery of written notice thereof by the Required Backstop Parties, (ii) that the Approval Order is reversed, stayed, dismissed, vacated, reconsidered, or modified or amended without the consent of the Required Backstop Parties, (iii) of a breach in any material respect by any Company Party of any representation or warranty in this Agreement, or of any such representation or warranty becoming inaccurate in any material respect, in each case if such breach or inaccuracy would, individually or in the aggregate for all such breaches or inaccuracies, prevent the satisfaction of any condition to the effectiveness of the Plan, or the Company’s or any Backstop Party’s performance of any of its obligations hereunder or under the RSA, if such breach or inaccuracy has not been waived by the Required Backstop Parties or cured within five (5) Business Days after the delivery of written notice thereof by the Backstop Parties, (iv) any of the Milestones is not satisfied, other than solely due to the actions of the Required Backstop Parties in violation of this Agreement, or (v) the Effective Date shall not have occurred within 80 days after the Petition Dateas of 11:59 p.m. prevailing Central Time on December 31, 2020; provided, however, that no Backstop Party may seek to terminate this Agreement pursuant to the foregoing clause (i) based upon a material breach arising out of the actions or omissions of such Backstop Party in breach of this Agreement).

Breach. Regardless of the termination of this Agreement pursuant to Section 8.10, each Party shall remain liable for any by such Party of this Agreement prior to its termination.

Specific Performance. The Parties agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with the terms hereof and that the Parties shall be entitled to an injunction or injunctions without the necessity of posting a bond to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Unless otherwise expressly stated in this Agreement, no right or remedy described or provided in this Agreement is intended to be exclusive or to preclude a Party from pursuing other rights and remedies to the extent available under this Agreement, at law or in equity.

No Reliance. No Backstop Party or any of its Affiliates shall have any duties or obligations to the other Backstop Parties in respect of this Agreement, the transactions contemplated hereby, the Definitive Documents or the Restructuring, except those expressly set forth

No Party may identify or use the name of any Backstop Party in connection with any press release or other public announcement related to this Agreement without the prior written consent of such Backstop Party, it being understood that nothing in this Section 8.17 shall prohibit any Party from filing any motions or other pleadings or documents with the Bankruptcy Court in connection with the Chapter 11 Cases or making any other filings or public announcements as may be required by applicable Law.
