Transactions; and (iii) the pursuit, approval and support of the Restructuring Transactions (including confirmation of the Plan). Furthermore, subject to the terms hereof, each of the Parties shall take such action as may be reasonably
necessary or reasonably requested by the other Parties to carry out the purposes and intent of this Agreement, or to 

  
 13 

	 	
effectuate the solicitation of the Plan and/or the Restructuring Transactions, including making and filing any required regulatory filings, executing and delivering any other necessary agreements
or instruments, and voting any claims against or interests in the Ultra Entities in favor of the Plan, and shall refrain from taking any action that would frustrate the purposes and intent of this Agreement. 

12. Transfers of Claims and Interests. 
  

	 	(a)	Each Plan Support Party shall not (i) sell, transfer, assign, pledge, grant a participation interest in, or otherwise dispose of, directly or indirectly, its right, title, or interest in respect of any of such Plan
Support Party’s claims against, or interests in, any Ultra Entity, as applicable, in whole or in part, or (ii) deposit any of such Plan Support Party’s claims against or interests in any Ultra Entity, as applicable, into a voting
trust, or grant any proxies, or enter into a voting agreement with respect to any such claims or interests (the actions described in clauses (i) and (ii) are collectively referred to herein as a “Transfer” and the Plan
Support Party making such Transfer is referred to herein as the “Transferor”), unless such Transfer is (i) to another Plan Support Party, (ii) to any other entity that first agrees in writing to be bound by the terms of
this Agreement by executing and delivering to Ultra a Transferee Joinder substantially in the form attached hereto as Exhibit C (the “Transferee Joinder”), or (iii) with respect to OTC Transfers of HoldCo Equity
Interests, in compliance with the Over-The-Counter Transfer Procedures attached hereto as Exhibit D; provided, that the Ultra Entities shall
cooperate and use reasonable efforts in facilitating OTC Transfers of HoldCo Equity Interests in accordance with the Plan Support Agreement and the Backstop Commitment Agreement. Upon compliance with the foregoing, the Transferor shall be deemed to
relinquish its rights (and be released from its obligations, except for any claim for breach of this Agreement that occurs prior to such Transfer) under this Agreement to the extent of such transferred rights and obligations. Any Transfer made in
violation of this Sub-Clause (a) of this Section 12 shall be deemed null and void ab initio and of no force or effect, regardless of any prior notice provided to
the Ultra Entities and/or any Plan Support Party, and shall not create any obligation or liability of any Ultra Entity or any other Plan Support Party to the purported transferee. 

 

	 	(b)	 Notwithstanding Sub-Clause (a) of this
Section 12, (i) an entity that is acting in its capacity as a Qualified Marketmaker shall not be required to be or become a Plan Support Party to effect any transfer (by purchase, sale, assignment, participation, or
otherwise) of any claim against, or interest in, any Ultra Entity, as applicable, by a Plan Support Party to a transferee; provided, that such transfer by a Plan Support Party to a transferee shall be in all other respects in accordance with
and subject to Sub-Clause (a) of this Section 12; and (ii) to the extent that a Plan Support

  
 14 

	 	
Party, acting in its capacity as a Qualified Marketmaker, acquires any claim against, or interest in, any Ultra Entity from a holder of such claim or interest who is not a Plan Support Party, it
may transfer (by purchase, sale, assignment, participation, or otherwise) such claim or interest without the requirement that the transferee be or become a Plan Support Party in accordance with this Section 12. For purposes
of this Sub-Clause (b), a “Qualified Marketmaker” means an entity that (x) holds itself out to the market as standing ready in the ordinary course of its
business to purchase from customers and sell to customers claims against, or interests in, the Ultra Entities (including debt securities or other debt) or to enter with customers into long and short positions in claims against, or interests in, the
Ultra Entities (including debt securities or other debt), in its capacity as a dealer or market maker in such claims against, or interests in, the Ultra Entities, and (y) is in fact regularly in the business of making a market in claims against
issuers or borrowers (including debt securities or other debt). 

 13. Further Acquisition of Claims or Interests.
Except as set forth in Section 12 hereof, nothing in this Agreement shall be construed as precluding any Plan Support Party or any of its controlled affiliates from acquiring additional claims arising from the HoldCo Notes or the HoldCo
Equity Interests, or interests in the instruments underlying the HoldCo Notes or the HoldCo Equity Interests; provided, that any such additional HoldCo Notes or HoldCo Equity Interests, or interests acquired by any Plan Support Party
or by any controlled affiliate of a Plan Support Party, shall automatically be subject to the terms and conditions of this Agreement and, if such acquiring Plan Support Party is a Backstop Party, to the terms and conditions of the Backstop
Commitment Agreement. Upon any such further acquisition by a Plan Support Party or any controlled affiliates of a Plan Support Party, such Plan Support Party shall promptly notify the Ultra Entities’ primary restructuring counsel, who will then
promptly notify the counsel to the HoldCo Noteholder Committee and counsel to the Equityholder Committee. 
 14. Consents and
Acknowledgments. 
  

	 	(a)	Each Party irrevocably acknowledges and agrees that this Agreement is not and shall not be deemed to be a solicitation for acceptances of the Plan. The acceptance of the Plan by each of the Plan Support Parties will not
be solicited until such Plan Support Party has received the Disclosure Statement and Solicitation Materials in accordance with applicable law, and will be subject to sections 1125, 1126, and 1127 of the Bankruptcy Code. 

 

	 	(b)	 By executing this Agreement, each Consenting HoldCo Noteholder (including, for the avoidance of doubt, any entity
that may execute this Agreement or a Transferee Joinder after the PSA Effective Date) irrevocably waives any Default or Event of Default as defined under the HoldCo Indentures that is caused by the Ultra Entities’ entry into this Agreement;
provided, however, that for the avoidance of doubt, each Party acknowledges and agrees that neither this Agreement nor the 

  
 15 

	 	
Restructuring Transactions contemplated hereunder shall be deemed to constitute a waiver of any Default or Event of Default that existed under the HoldCo Indentures prior to entry into this
Agreement. 

 15. Representations and Warranties. 

 

	 	(a)	Each Plan Support Party hereby represents and warrants on a several and not joint basis for itself and not any other person or entity that the following statements are true, correct, and complete, to the best of its
actual knowledge, as of the date hereof: 

  

	 	(i)	it has the requisite organizational power and authority to enter into this Agreement and to carry out the transactions contemplated by, and perform its respective obligations under, this Agreement; 

 

	 	(ii)	the execution and delivery of this Agreement and the performance of its obligations hereunder have been duly authorized by all necessary corporate or other organizational action on its part; 

 

	 	(iii)	the execution and delivery by it of this Agreement does not (A) violate its certificates of incorporation, or bylaws, or other organizational documents, or those of any of its affiliates in any material respect, or
(B) result in a breach of, or constitute (with due notice or lapse of time or both) a default (other than, for the avoidance of doubt, a breach or default that would be triggered as a result of the Chapter 11 Cases or any Ultra Entity’s
undertaking to implement the Restructuring Transactions through the Chapter 11 Cases) under any material contractual obligation to which it or any of its affiliates is a party; 

 

	 	(iv)	 the execution, delivery, and performance by it of this Agreement does not require any registration or filing
with, the consent or approval of, notice to, or any other action with any federal, state, or other governmental authority or regulatory body, except (i) any of the foregoing as may be necessary and/or required for disclosure by the Securities
and Exchange Commission and applicable state securities or “blue sky” laws, (ii) any of the foregoing as may be necessary and/or required in connection with the Chapter 11 Cases, including the approval of the Disclosure Statement and
confirmation of the Plan, (iii) filings of amended certificates of incorporation or articles of formation or other organizational documents with applicable state authorities, and other registrations, filings, consents, approvals, notices, or
other actions that are reasonably necessary to maintain permits, licenses, qualifications, and governmental approvals to carry on the business of the Ultra Entities, and (iv) any other registrations, filings, consents, approvals, notices, or
other actions, the failure of which to make, 

  
 16 

	 	
obtain or take, as applicable, would not be reasonably likely, individually or in the aggregate, to materially delay or materially impair the ability of any Party hereto to consummate the
transactions contemplated hereby; 

  

	 	(v)	subject to the provisions of sections 1125 and 1126 of the Bankruptcy Code, this Agreement is its legally valid and binding obligation, enforceable against it in accordance with its terms, except as enforcement may be
limited by bankruptcy, insolvency, reorganization, moratorium, or other similar laws relating to or limiting creditors’ rights generally, or by equitable principles relating to enforceability; 

 

	 	(vi)	it is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act of 1933, as amended (the “Securities Act”), with sufficient
knowledge and experience to evaluate properly the terms and conditions of this Agreement, and has been afforded the opportunity to discuss other information concerning the Ultra Entities with the Ultra Entities’ representatives, and to
consult with its legal and financial advisors with respect to its investment decision to execute this Agreement, and it has made its own analysis and decision to enter into this Agreement; and 

 

	 	(vii)	it (A) either (1) is an economic interest holder of the claims and interests, or (2) has all necessary investment or voting discretion with respect to the principal amount of claims and interests, in each
case, as identified in schedules delivered to the Ultra Entities by counsel to the HoldCo Noteholder Committee and counsel to the Equityholder Committee simultaneously with the execution of this Agreement, or otherwise separately identified in a
schedule delivered on behalf of such Plan Support Party (all of which schedules shall be held in confidence pursuant to Section 27(b) hereof); and (B) to the knowledge of the individuals working on the Restructuring Transactions, does
not directly or indirectly own economic interests in any HoldCo Notes or HoldCo Equity Interests, other than as identified in separate schedules to the Ultra Entities delivered by counsel to the HoldCo Noteholder Committee and counsel to the
Equityholder Committee simultaneously with the execution of this Agreement (all of which schedules shall be held in confidence pursuant to Section 27(b) hereof), or otherwise separately identified in a schedule delivered on behalf of such
Plan Support Party, simultaneously with the execution of this Agreement. 

  
 17 

	 	(b)	Each Ultra Entity hereby represents and warrants on a joint and several basis (and not any other person or entity other than the Ultra Entities) that the following statements are true, correct, and complete, to the best
of its actual knowledge, as of the date hereof: 

  

	 	(i)	it has the requisite corporate or other organizational power and authority to enter into this Agreement and to carry out the transactions contemplated by, and perform its respective obligations under, this Agreement;
and 

  

	 	(ii)	the execution and delivery of this Agreement and the performance of its obligations hereunder have been duly authorized by all necessary corporate or other organizational action on its part of each of the corporate
entities that comprise the Ultra Entities. 

 16. Waiver. If the transactions contemplated herein are or are not
consummated, or following the occurrence of a Termination Date, if applicable, nothing herein shall be construed as a waiver by any Party of any or all of such Party’s rights, other than as provided in Section 14
hereof, and the Parties expressly reserve any and all of their respective rights. The Parties acknowledge that this Agreement, the Plan, and all negotiations relating hereto are part of a proposed settlement of matters that could otherwise be the
subject of litigation. Pursuant to Rule 408 of the Federal Rules of Evidence, any applicable state rules of evidence, and any other applicable law, foreign or domestic, the Plan Term Sheet, this Agreement, the Plan, any related documents, and all
negotiations relating thereto shall not be admissible into evidence in any proceeding other than a proceeding to enforce its terms. 
 17.
Relationship Among Parties. 
  

	 	(a)	 Notwithstanding anything herein to the contrary, the duties and obligations of the Plan Support Parties, on the
one hand, and the Ultra Entities, on the other hand, arising under this Agreement shall be several, not joint. No Party shall have any responsibility by virtue of this Agreement for any trading by any other entity. No prior history, pattern, or
practice of sharing confidences among or between the Parties shall in any way affect or negate this Agreement. The Parties hereto acknowledge that this Agreement does not constitute an agreement, arrangement, or understanding with respect to acting
together for the purpose of acquiring, holding, voting, or disposing of any equity securities of the Ultra Entities and the Plan Support Parties do not constitute a “group” within the meaning of Rule
13d-5 under the Securities Exchange Act of 1934, as amended. Nothing contained herein or any of the Definitive Documentation and no action taken by any Plan Support Party pursuant to this Agreement shall be
deemed to constitute or to create a presumption by any of the Parties that the Plan Support Party are in any way acting in concert or as a “group” (or a joint venture, partnership or association), and the Ultra Entities will not assert any
such claim with respect to such obligations or the transactions contemplated by this Agreement or any Definitive Documentation, and the Ultra Entities acknowledge that neither the Consenting HoldCo Equityholders nor the consenting HoldCo

  
 18 

	 	
Noteholders are acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or the Definitive Documentation. The Ultra Entities acknowledge
and each Consenting HoldCo Equityholder and each Consenting HoldCo Noteholder confirms that it has independently participated in the negotiation of the transactions contemplated under this Agreement and the Definitive Documentation with the advice
of counsel and advisors. 

  

	 	(b)	In connection with any matter requiring consent or a request of the Majority Consenting HoldCo Noteholders or Majority Consenting HoldCo Equityholders under this Agreement, there is no requirement or obligation that
such holders agree among themselves to take such action and no agreement among such holders with respect to any such action. In connection with any matter that may be requested by the Majority Consenting HoldCo Noteholders or Majority Consenting
HoldCo Equityholders, each such holder may, through its counsel, make such request; provided, that Ultra will only be required to take such action if it receives the request of the Majority Consenting HoldCo Noteholders or Majority Consenting
HoldCo Equityholders, as the case may be. In connection with any matter requiring consent of the Majority Consenting HoldCo Noteholders or Majority Consenting HoldCo Equityholders hereunder, Ultra will solicit consent independently from each
such holder or its respective counsel; provided, that such consent shall only be granted if the approval of the Majority Consenting HoldCo Noteholders or Majority Consenting HoldCo Equityholders (as applicable) is obtained. 

 

	 	(c)	It is understood and agreed that none of the Plan Support Parties has any duty of trust or confidence in any form with any other Plan Support Party, the Ultra Entities, or any of the Ultra Entities’ creditors or
other stakeholders and, except as expressly provided in this Agreement, there are no agreements, commitments or undertakings by, among or between any of them with respect to the subject matter hereof. For the avoidance of doubt, the foregoing
sentence does not include any fiduciary obligations owed by any Plan Support Party that has been appointed an officer of any Ultra Entity. 

  

	 	(d)	 The Ultra Entities shall notify the Plan Support Parties in writing as promptly as practicable and in no event
more than two (2) business days after receipt by the Ultra Entities or their representatives or agents, as applicable, of any written (including email), definitive proposal or offer from any person or entity to effect a restructuring of the
Ultra Entities, any alternative transaction or restructuring or a transaction in conflict with the Restructuring Transactions or any request for confidential information relating to the Ultra Entities, which notice, subject to confidentiality
obligations shall indicate the identity of the person or entity making the proposal, offer or request. The Ultra Entities shall additionally, subject to confidentiality obligations provide copies of

  
 19 

	 	
such written proposals or offers received by any of the Ultra Entities, as applicable, as promptly as practicable and in no event more than two (2) business days after receipt by the Ultra
Entities or their representatives or agents. 

 18. Specific Performance. It is understood and agreed by the Parties
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. 

19. Governing Law & Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State
of New York, without regard to such state’s choice of law provisions which would require the application of the law of any other jurisdiction, except where preempted by the Bankruptcy Code. By its execution and delivery of this Agreement, each
Party agrees that the Bankruptcy Court shall have exclusive jurisdiction of all matters arising out of or in connection with this Agreement. By executing and delivering this Agreement, and upon commencement of the Chapter 11 Cases, each of the
Parties irrevocably and unconditionally submits to the personal jurisdiction of the Bankruptcy Court solely for purposes of any action, suit, proceeding, or other contested matter arising out of or relating to this Agreement, or for recognition or
enforcement of any judgment rendered or order entered in any such action, suit, proceeding, or other contested matter. 
 20. Waiver of
Right to Trial by Jury. Each of the Parties waives any right to have a jury participate in resolving any dispute, whether sounding in contract, tort or otherwise, between any of the Parties arising out of, connected with, relating to, or
incidental to the relationship established between any of them in connection with this Agreement. Instead, any disputes resolved in court shall be resolved in a bench trial without a jury. 

21. Successors and Assigns. Except as otherwise provided in this Agreement, this Agreement is intended to bind and inure to the benefit
of each of the Parties and each of their respective permitted successors, assigns, heirs, executors, administrators, and representatives. 

22. No Third-Party Beneficiaries. Unless expressly stated herein, this Agreement shall be solely for the benefit of the Parties and no
other person or entity shall be a third-party beneficiary of this Agreement. 
 23. Notices. All notices (including, without
limitation, any notice of termination or breach) and other communications from any Party hereunder shall be in writing and shall be deemed to have been duly given if personally delivered by courier service, messenger, email, or facsimile to the
other Parties at the applicable addresses below, or such other addresses as may be furnished hereafter by notice in writing. Any notice of termination or breach shall be delivered to all other Parties.

25. Amendments. Except as otherwise provided herein, this Agreement (including the Exhibits and Schedules) may not be modified,
amended, or supplemented without the prior written consent of the Ultra Entities and the Required Consenting Parties; provided, that any modification of, amendment or supplement to, any exhibit hereto that materially and adversely affects any
Plan Support Party shall require the prior written consent of each Plan Support Party so affected (it being understood that any materially adverse change in the economic treatment provided to any holder of HoldCo Notes or HoldCo Equity Interests
under the Plan Term Sheet, including any change to the “Equity splits” set forth in the Plan Term Sheet, shall constitute a material adverse change for purposes of this section); provided, further, that the prior written
consent of all Parties shall be required to modify, amend or supplement (a) any of Sections 1, 7, 8, 9, or 25 hereof or (b) the definition of “Majority Consenting HoldCo Noteholders,”

 26. Restructuring Fees and
Expenses. Subject to entry of the Approval Order, regardless of whether a restructuring is implemented, the Ultra Entities shall pay all accrued and ongoing reasonable and documented fees, costs and expenses of counsel and other professional

co-counsel to the Equityholder Committee, (b) Gray, Reed & McGraw, P.C., as co-counsel to the Equityholder Committee, (c) Peter J. Solomon Company, as

 22 

 
were incurred (i) on or prior to the Effective Date or (ii) within three (3) months following the Effective Date, but only to the extent such costs and expenses relate to services
rendered in the course of consummation and implementation of the Plan or as contemplated under the Plan, whether such fees, costs and expenses were previously incurred or invoiced (the “Restructuring Expenses”), on a regular and
continuing basis, within two (2) business days following fifteen (15) calendar days after delivery of an invoice to the Ultra Parties (redacted for privilege and work product), each in accordance with the agreements between the Ultra
Entities and the applicable firm, without any requirement for Bankruptcy Court review or further Bankruptcy Court order. The Ultra Entities shall have ten (10) days following their receipt of any invoices to review and object to the
reasonableness of the fees and expenses included in such invoice. If any such objection is not resolved within ten (10) days after such objection is interposed, a hearing with respect thereto shall be conducted at a regularly scheduled omnibus
hearing in the Chapter 11 Cases; provided, that the Ultra Entities shall pay any undisputed portion of such fees, costs, and expenses on the first Thursday following fifteen (15) days after the initial presentment of such invoices. To
the extent not previously paid by the Ultra Entities, the Ultra Entities shall pay all accrued Restructuring Expenses, including estimated amounts, through the Effective Date on the Effective Date in cash. Restructuring Expenses invoiced after the
Effective Date for services rendered no later than three (3) months after the Effective Date and otherwise payable under this Section 26 shall be paid promptly by the reorganized Ultra Entities following receipt of

 27. Confidentiality and Publicity. 
  

	 	(a)	Other than as may be required by applicable law and regulation or by any governmental or regulatory authority, no Party shall issue any press release, make any filing with the SEC (other than required under applicable
securities law and regulation as reasonably determined in good faith by outside counsel to the Ultra Entities) or make any other public announcement regarding this Agreement without the consent of the Ultra Entities and the Required Consenting
Parties, which consent shall not be unreasonably delayed, conditioned, or withheld, and each Party shall coordinate with the other Parties regarding any public statements made, including any communications with the press, public filings or filings
with the SEC, with respect to this Agreement; for the avoidance of doubt, each Party shall have the right, without any obligation to any other Party, to decline to comment to the press with respect to this Agreement. 

 

	 	(b)	 Under no circumstances may any Party make any public disclosure of any kind that would disclose (i) the
particular holdings of any Plan Support Party or (ii) the identity of any Plan Support Party, in each case without the prior written consent of such Plan Support Party; provided, that (W) the Ultra Entities may disclose such
identities and the aggregate holdings of the Consenting HoldCo Noteholders and the Consenting HoldCo Equityholders, respectively, but not individual holdings of any individual Plan Support Party (which shall be treated as “advisors’ eyes
only”) in any filing with the SEC in respect of this Agreement and in any materials filed in the Chapter 11 Cases in support of the Approval Motion; (X) the Ultra 

  
 23 

	 	
Entities may disclose such identities or amounts without consent to the extent that, upon the advice of counsel, it is required to do so by any governmental or regulatory authority (including as
it may be directed by the Securities and Exchange Commission) or court of competent jurisdiction (including the Bankruptcy Court), or by applicable law, in which case the Ultra Entities, prior to making such disclosure, shall allow the Plan Support
Parties to whom such disclosure relates reasonable time at its own cost to seek a protective order with respect to such disclosures, (Y) the Ultra Entities may disclose the existence and terms of this Agreement, including the execution of this
Agreement by the Plan Support Parties, and (Z) the Ultra Entities may disclose the aggregate percentage or aggregate principal amount held by the Consenting HoldCo Noteholders and the Consenting HoldCo Equityholders, respectively. The Ultra
Entities shall not use the name of any Plan Support Party in any press release without such Party’s prior written consent. 

  

	 	(c)	The Ultra Entities will issue a press release announcing this Agreement on November 22, 2016 and provide the HoldCo Noteholder Committee and counsel to the Equityholder Committee with a draft of such press release
and all future press releases, public filings, public announcements or other communications with any news media relating to this Agreement or the Restructuring Transactions at least one (1) business day prior to issuing such releases, filings,
announcements or other communications; provided, that the Ultra Entities shall be under no obligation to consult with, or obtain the prior approval of, any other Party as it relates to communications with vendors, customers and other third
parties regarding the general nature of the Restructuring Transactions. 

 28. Reservation of Rights. Except as
expressly provided in this Agreement or the Plan Term Sheet, nothing herein is intended to, or does, in any manner waive, limit, impair, or restrict the ability of any Party to protect and preserve its rights, remedies and interests, including
without limitation, its claims against any of the other Parties. 
 29. Counterparts. This Agreement may be executed in one or more
counterparts, each of which, when so executed, shall constitute the same instrument, and the counterparts may be delivered by facsimile transmission or by electronic mail in portable document format (.pdf). 

30. Headings. The section headings of this Agreement are for convenience of reference only and shall not, for any purpose, be deemed a
part of this Agreement. 

  
 24 

 31. Interpretation. This Agreement is the product of negotiations among the Parties, and
the enforcement or interpretation hereof, is to be interpreted in a neutral manner, and any presumption with regard to interpretation for or against any Party by reason of that Party having drafted or caused to be drafted this Agreement or any
portion hereof, shall not be effective in regard to the interpretation hereof.

such Commitment Party, such transferee and the Company shall have duly executed and delivered to each other a copy of such joinder agreement, and (iii) with respect to any transferee that is a Commitment Party, such transferee and the
transferring Commitment Party shall have duly executed and delivered to the Debtors written notice of such Transfer in form and substance reasonably acceptable to the Debtors, and the Debtors shall have delivered countersigned copies of such notice
to such transferee and the transferring Commitment Party 

  
 24 

 
and to counsel to the Commitment Parties; provided, further, that the transfer to any such transferee who is not a Commitment Party shall be on five (5) Business Days’
notice to the Company and shall be effective unless the Company delivers a written objection to the transferring Commitment Party within such period, setting forth reasonable grounds for such objection. Upon compliance with this paragraph, the
transferring Commitment Party shall be deemed to relinquish its rights (and be released from its obligations, except for any claim for breach of this Agreement that occurs prior to such Transfer) under this Agreement to the extent of such
transferred rights and obligations, and the transferee shall be fully bound as a Commitment Party hereunder for all purposes of this Agreement. Any Transfer made in violation of this paragraph shall be deemed null and void ab initio and of no force
or effect, regardless of any prior notice provided to the Debtors or any Commitment Party, and shall not create any obligation or liability of any Debtor or any other Commitment Party to the purported transferee. Upon the effectiveness of any
Transfer of all or a portion of a Backstop Commitment pursuant to this Section 2.6, the Company shall update Schedule IA and/or Schedule IB hereto, as applicable, to reflect such Transfer, and such updates shall not
constitute an amendment to this Agreement. The Company shall provide a copy of any such Transfer notice, Joinder Agreement or other agreement entered into in connection with any Transfers pursuant to this Section 2.6,
together with any updates to Schedules IA and/or IB hereto, to counsel to the Commitment Parties promptly, and in any event within one (1) Business Day following receipt by the Company of any such agreement or notice or the date of any such
update, as applicable. 
 (d) Each Commitment Party, severally and not jointly, agrees that it will not Transfer, at any time prior to the
Closing Date or the earlier termination of this Agreement in accordance with its terms, any of its rights and obligations under this Agreement to any Person other than in accordance with Section 2.6(a), Section 2.6(b) or Section
2.6(c), as applicable. After the Closing Date, nothing in this Agreement shall limit or restrict in any way the ability of any Commitment Party (or any permitted transferee thereof) to Transfer any of the Common Shares or any interest therein;
provided, that any such Transfer shall be made pursuant to an effective registration statement under the Securities Act or an exemption from the registration requirements thereunder and pursuant to applicable securities Laws. For the
avoidance of doubt, notwithstanding anything to the contrary in this Agreement, nothing contained in this Agreement shall prohibit or restrict the ability of any Commitment Party to Transfer its HoldCo Notes and/or HoldCo Noteholders Subscription
Rights or Equity Interests and/or HoldCo Equityholders Subscription Rights, as applicable, at any time to any Person; provided, however, any Transfer of HoldCo Notes by a HoldCo Noteholders Commitment Party shall be in accordance with

replacement, restatement, reinstatement, or other change to, any Material Contract that does not result in an increase (on a present value basis, applying a reasonable discount rate) of the Company’s liabilities with respect to such Material
Contract (other than any Material Contracts that are otherwise addressed by clause (4) below) may be accomplished without the consent of the Requisite Commitment Parties; but the following shall be deemed to occur outside of the ordinary course

delivered to each of the HoldCo Noteholder Committee and Equityholder Committee (which notice will be deemed delivered if given in writing to Paul, Weiss and Brown, Rudnick), such consent shall be deemed to have been granted by the Requisite
Commitment Parties. Except as otherwise provided in this Agreement, nothing in this Agreement shall give the Commitment Parties, directly or indirectly, any right to control or direct the operations of the Debtors. Prior to the Closing Date, the
Debtors shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision of the business of the Debtors. 

Section 6.4 Access to Information; Confidentiality. 

(a) Subject to applicable Law and Section 6.4(b), upon reasonable notice during the Pre-Closing

business, properties and personnel as may reasonably be requested by any such party; provided, that the foregoing shall not require the Company (i) to permit any inspection, or to disclose any information, that in the reasonable judgment

consent of such third party to such inspection or disclosure, (ii) to disclose any legally privileged information of any of the Debtors or (iii) to violate any applicable Laws or Orders. All requests for information and access made in
accordance with this Section 6.4 shall be directed to an executive officer of the Company or such Person as may be designated by the Company’s executive officers. 

(b) From and after the date hereof until the date that is one (1) year after the expiration of the
Pre-Closing Period, each Commitment Party shall, and shall cause its Representatives to, (i) keep confidential and not provide or disclose to any Person any documents or information received or otherwise
obtained by such Commitment Party or its Representatives pursuant to Section 6.4(a) or in connection with a request for approval pursuant to Section 6.3 (except that provision or disclosure may be made to any
Affiliate or Representative of such Commitment Party who needs to know such information for purposes of this Agreement or the other Transaction Agreements and who agrees to observe the terms of this Section 6.4(b) (and such Commitment Party
will remain liable for any breach of such terms by any such Affiliate or Representative)), and (ii) not use such documents or information for any purpose other than in connection with this Agreement or the other Transaction Agreements or the
transactions contemplated hereby or thereby. Notwithstanding the foregoing, the immediately preceding sentence shall not apply in respect of documents or information that (A) is now or subsequently becomes generally available to the public

or applicable securities exchange rules; provided, that, such Commitment Party or such Representative shall provide the Company with prompt written notice of such legal compulsion and cooperate with the Company to obtain a protective Order or
similar remedy to cause such information or documents not to be disclosed, including interposing all available objections thereto, at the Company’s sole cost and expense; provided, further, that, in the event that such protective
Order or other similar remedy is not obtained, the disclosing party shall furnish only that portion of such information or documents that is legally required to be disclosed and shall exercise its commercially reasonable efforts (at the
Company’s sole cost and expense) to obtain assurance that confidential treatment will be accorded such disclosed information or documents. The provisions of this Section 6.4(b) shall not apply to any Commitment Party that, as of the date
hereof, is party to a confidentiality or non-disclosure agreement with the Debtors, for so long as such agreement remains in full force and effect. 

  
 42

necessary, proper or advisable in order to consummate and make effective the transactions contemplated by this Agreement and the Plan, including using commercially reasonable efforts in:

accordance with the Plan Support Agreement, the Commitment Parties and the Company shall have the right to review in advance, and to the extent practicable each will consult with the other on all of the information relating to Commitment Parties or
the Company, as the case may be, and any of their respective Subsidiaries, that appears in any filing made with, or written materials submitted to, any Governmental Entity in connection with the transactions contemplated by this Agreement or the
Plan; provided, however, that the Commitment Parties are not required to provide for review in advance declarations or other evidence submitted in connection with any filing with the Bankruptcy Court. In exercising the foregoing
rights, the Parties shall act as reasonably and as promptly as practicable. 
 (c)    Without limitation to
Section 6.1 or Section 6.2, to the extent exigencies permit, the Company shall provide or cause to be provided to the Commitment Parties a draft of all motions, applications, pleadings, schedules,

supporting documentation) in the Chapter 11 Cases relating to or affecting the Transaction Agreements or the Registration Rights Agreement in accordance with the Plan Support Agreement and in no
event less than 48 hours before such motions, applications, pleadings, schedules, Orders, reports or other material papers are filed with the Bankruptcy Court. All such motions, applications, pleadings, schedules, Orders, reports and other material
papers shall be in form and substance reasonably satisfactory to the Requisite Commitment Parties and the Company. 
 (d) Nothing contained
in this Section 6.5(d) shall limit the ability of any Commitment Party to consult with the Debtors, to appear and be heard, or to file objections, concerning any matter arising in the Chapter 11 Cases to the extent not inconsistent with
the Plan Support Agreement.

ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY OTHER APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN AVAILABLE EXEMPTION FROM
REGISTRATION THEREUNDER.” 
 In the event that any such shares are uncertificated, such shares shall be subject to a restrictive notation substantially
similar to the Legend in the stock ledger or other appropriate records maintained by the Reorganized Company or agent and the term “Legend” shall include such restrictive notation. The Reorganized Company shall remove the Legend (or
restrictive notation, 

  
 45

request, at any time after the restrictions described in such Legend cease to be applicable, including, as applicable, when such shares may be sold under Rule 144 of the Securities Act. The Reorganized Company may reasonably request such opinions,
certificates or other evidence that such restrictions no longer apply as a condition to removing the Legend.

INDEMNIFICATION AND CONTRIBUTION 

Section 8.1 Indemnification Obligations. Following the entry of the Approval Order, the Company, the Reorganized Debtors and the
other Debtors (the “Indemnifying Parties” and each, an “Indemnifying Party”) shall, jointly and severally, indemnify and hold harmless each Commitment Party and its Affiliates, equity holders, members,
partners, general partners, managers and its and their respective Representatives and controlling persons (each, an “Indemnified Person”) from and against any and all losses, claims, damages, liabilities and costs and
expenses (other than Taxes of the Commitment Parties except to the extent otherwise provided for in this Agreement) arising out of a claim asserted by a third party (collectively, “Losses”) that any such Indemnified Person
may incur or to which any such Indemnified Person may become subject arising out of or in connection with this Agreement and the obligations hereunder, including the Backstop Commitment, the Rights Offerings, the payment of the Commitment Premium or
the use of the proceeds of the Rights Offerings, or any claim, challenge, litigation, investigation or proceeding relating to any of the foregoing, regardless of whether any Indemnified Person is a party thereto, whether or not such proceedings are
brought by the Company, the Reorganized Debtors, the other Debtors, their respective equity holders, Affiliates, creditors or any other Person, and reimburse each Indemnified Person upon demand for reasonable documented (with such documentation
subject to redaction to preserve attorney client and work product privileges) legal or other third-party expenses incurred in connection with investigating, preparing to defend or defending, or providing evidence in or preparing to serve or serving
as a witness with respect to, any lawsuit, investigation, claim or other proceeding relating to any of the foregoing (including in connection with the enforcement of the indemnification obligations set forth herein), irrespective of whether or not
the transactions contemplated by this Agreement or the Plan are consummated or whether or not this Agreement is terminated; provided, that the foregoing indemnity will not, as to any Indemnified Person, apply to Losses (a) as to a
Defaulting Commitment Party, its Related Parties or any Indemnified Person related thereto, caused by a Commitment Party Default by such Commitment Party, or (b) to the extent they are found by a final,
non-appealable judgment of a court of competent jurisdiction, whether such judgment is in such underlying action, suit or proceeding, or otherwise, to arise from the bad faith, willful misconduct or gross
negligence of such Indemnified Person. 
 Section 8.2 Indemnification Procedure. Promptly after receipt by an Indemnified
Person of notice of the commencement of any claim, challenge, litigation, investigation or proceeding (an “Indemnified Claim”), such Indemnified Person will, if a claim is to be made hereunder against the Indemnifying Party
in respect thereof, notify the Indemnifying Party in writing of the commencement thereof; provided, that (a) the omission to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have
hereunder except to the extent it has been materially prejudiced by such failure and 

  
 52 

 
(b) the omission to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have to such Indemnified Person otherwise than on account of this
Article VIII. In case any such Indemnified Claims are brought against any Indemnified Person and it notifies the Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate
therein, and, at its election by providing written notice to such Indemnified Person, the Indemnifying Party will be entitled to assume the defense thereof, with counsel reasonably acceptable to such Indemnified Person; provided, that if the
parties (including any impleaded parties) to any such Indemnified Claims include both such Indemnified Person and the Indemnifying Party and based on advice of such Indemnified Person’s counsel there are legal defenses available to such
Indemnified Person that are different from or additional to those available to the Indemnifying Party, such Indemnified Person shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense
of such Indemnified Claims. Upon receipt of notice from the Indemnifying Party to such Indemnified Person of its election to so assume the defense of such Indemnified Claims with counsel reasonably acceptable to the Indemnified Person, the
Indemnifying Party shall not be liable to such Indemnified Person for expenses incurred by such Indemnified Person in connection with the defense thereof or participation therein (other than reasonable costs of investigation) unless (i) such
Indemnified Person shall have employed separate counsel (in addition to any local counsel) in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence (it being understood, however, that
the Indemnifying Party shall not be liable for the expenses of more than one separate counsel representing the Indemnified Persons who are parties to such Indemnified Claims (in addition to one local counsel in each jurisdiction in which local
counsel is required)), (ii) the Indemnifying Party shall not have employed counsel reasonably acceptable to such Indemnified Person to represent such Indemnified Person within a reasonable time after the Indemnifying Party has received notice
of commencement of the Indemnified Claims from, or delivered on behalf of, the Indemnified Person, (iii) after the Indemnifying Party assumes the defense of the Indemnified Claims, the Indemnified Person determines in good faith that the
Indemnifying Party has failed or is failing to defend such claim and provides written notice of such determination and the basis for such determination, and such failure is not reasonably cured within ten (10) Business Days of receipt of such
notice, or (iv) the Indemnifying Party shall have authorized in writing the employment of counsel for such Indemnified Person. Notwithstanding anything herein to the contrary, the Debtors shall have sole control over any Tax controversy or Tax
audit and shall be permitted to settle any liability for Taxes of the Debtors. 
 Section 8.3 Settlement of Indemnified Claims.
In connection with any Indemnified Claim for which an Indemnified Person is assuming the defense in accordance with this Article VIII, the Indemnifying Party shall not be liable for any settlement of any Indemnified Claims effected by such
Indemnified Person without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed). If any settlement of any Indemnified Claims is consummated with the written consent of the
Indemnifying Party or if there is a final judgment for the plaintiff in any such Indemnified Claims, the Indemnifying Party agrees to indemnify and hold harmless each Indemnified Person from and against any and all Losses by reason of such
settlement or judgment to the extent such Losses are otherwise subject to indemnification by the Indemnifying Party hereunder in accordance with, and subject to the limitations of, this Article VIII. The Indemnifying Party shall not, without
the prior written consent of an Indemnified Person (which consent shall be 

  
 53 

 
granted or withheld, conditioned or delayed in the Indemnified Person’s sole discretion), effect any settlement of any pending or threatened Indemnified Claims in respect of which indemnity
or contribution has been sought hereunder by such Indemnified Person unless (i) such settlement includes an unconditional release of such Indemnified Person in form and substance satisfactory to such Indemnified Person from all liability on the
claims that are the subject matter of such Indemnified Claims and (ii) such settlement 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 Person. 

Section 8.4 Contribution. If for any reason the foregoing indemnification is unavailable to any Indemnified Person or
insufficient to hold it harmless from Losses that are subject to indemnification pursuant to Section 8.1, then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Person as a result of
such Loss in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party, on the one hand, and such Indemnified Person, on the other hand, but also the relative fault of the Indemnifying Party, on
the one hand, and such Indemnified Person, on the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Indemnifying Party, on the one hand, and all Indemnified Persons, on the other
hand, shall be deemed to be in the same proportion as (a) the total value received or proposed to be received by the Company and the Reorganized Debtors pursuant to the issuance and sale of the Rights Offering Shares in the Rights Offerings
contemplated by this Agreement and the Plan bears to (b) the Commitment Premium paid or proposed to be paid to the Commitment Parties. The Indemnifying Parties also agree that no Indemnified Person shall have any liability based on their
comparative or contributory negligence or otherwise to the Indemnifying Parties, any Person asserting claims on behalf of or in right of any of the Indemnifying Parties, or any other Person in connection with an Indemnified Claim. 

Section 8.5 Treatment of Indemnification Payments. All amounts paid by an Indemnifying Party to an Indemnified Person under this
Article VIII shall, to the extent permitted by applicable Law, be treated as adjustments to the Per Share Purchase Price for all Tax purposes. The provisions of this Article VIII are an integral part of the transactions contemplated by
this Agreement and without these provisions the Commitment Parties would not have entered into this Agreement. The Approval Order shall provide that the obligations of the Company and the Reorganized Debtors under this Article VIII shall
constitute allowed administrative expenses of the Debtors’ estate under sections 503(b) and 507 of the Bankruptcy Code and are payable without further Order of the Bankruptcy Court, and that the Company and the Reorganized Debtors may
comply with the requirements of this Article VIII without further Order of the Bankruptcy Court. 
 Section 8.6 No
Survival. All representations, warranties, covenants and agreements made in this Agreement shall not survive the Closing Date except for covenants and agreements that by their terms are to be satisfied after the Closing Date, which covenants and
agreements shall survive until satisfied in accordance with their terms.

 (f) the Plan Support
Agreement is terminated in accordance with its terms; or 
 (g) the Closing Date has not occurred by the Outside Date (as the same may be
extended pursuant to Section 9.2(a) or Section 2.3(e)), unless prior thereto the Effective Date occurs and each Rights Offering has been consummated; provided, that the Company shall not have the right to terminate this
Agreement pursuant to this Section 9.3(g) if it is then in willful or intentional breach of this Agreement. 
 Section 9.4
Effect of Termination. 
 (a) Upon termination of this Agreement pursuant to this Article IX, this Agreement shall forthwith
become void and there shall be no further obligations or liabilities on the part of the Parties; provided, that (i) the obligations of the Debtors to pay the Expense Reimbursement pursuant to and in accordance with
Section 3.3 and to pay the Commitment Premium pursuant to and in accordance with Section 3.2 shall survive the termination of this Agreement and shall remain in full force and effect in case, until
such obligations have been satisfied, (ii) the provisions set forth in Article VIII and Article X shall survive the termination of this Agreement in accordance with their terms, in each case so long as the Approval Order has been
entered by the Bankruptcy Court prior to the date of termination, and (iii) subject to Section 10.10, nothing in this Section 9.4 shall relieve any Party from liability for its gross
negligence or any willful or intentional breach of this Agreement. For purposes of this Agreement, “willful or intentional breach” means a breach of this Agreement that is a consequence of an act undertaken by the breaching
Party with the knowledge that the taking of such act would, or would reasonably be expected to, cause a breach of this Agreement. 
 (b) If
this Agreement is terminated for any reason other than by the Company under Section 9.3(b), the Debtors shall, promptly after the date of such termination, pay the Commitment Premium set forth by Section 3.2 and any
provisos applicable to Section 3.2(a) entirely in cash to the Commitment Parties or their designees. To the extent that all amounts due in respect of the Commitment Premium pursuant to this Section 9.4(b) have actually been paid by the
Debtors to the Commitment Parties in connection with a termination of this Agreement, the Commitment Parties shall not have any additional recourse against the Debtors for any obligations or liabilities relating to or arising from this Agreement,
except for liability for bad faith, willful misconduct or gross negligence of this Agreement pursuant to Section 8.1 or except as otherwise provided in Section 9.4(a). Except as set forth in this Section 9.4(b), the
Commitment Premium shall not be payable upon the termination of this Agreement. The Commitment Premium shall, pursuant to the Approval Order, constitute allowed administrative expenses of the Debtors’ estate under sections 503(b)
and 507 of the Bankruptcy Code.

under applicable securities law and regulation as reasonably determined in good faith by outside counsel to the Debtors) or make any other public announcement regarding this Agreement without the consent of the Debtors and the Requisite Commitment
Parties, which consent shall not be unreasonably delayed, conditioned, or withheld, and each Party shall coordinate with the other Parties regarding any public statements made, including any communications with the press, public filings or filings
with the SEC, with respect to this Agreement; for the avoidance of doubt, each Party shall have the right, without any obligation to any other Party, to decline to comment to the press with respect to this Agreement. 

(b) Under no circumstances may any Party make any public disclosure of any kind that would disclose (i) the particular holdings of any
Commitment Party or (ii) the identity of any Commitment Party, in each case without the prior written consent of such Commitment Party; provided, that (w) the Debtors may disclose such identities and the aggregate holdings of the

communications with any news media relating to this Agreement or the Restructuring Transactions at least one (1) business day prior to issuing such releases, filings, announcements or other communications; provided, that the Debtors
shall be under no obligation to consult with, or obtain the prior approval of, any other Party as it relates to communications with vendors, customers and other third parties regarding the general nature of the Restructuring Transactions. 

Section 10.13 Settlement Discussions. This Agreement and the transactions contemplated herein are part of a proposed settlement
of a dispute between the Parties. Nothing herein shall be deemed an admission of any kind. Pursuant to Section 408 of the U.S. Federal Rules of Evidence and any applicable state rules of evidence, this Agreement and all negotiations

the terms of this Agreement). 
 Section 10.14 No Recourse. Notwithstanding anything that may be expressed or implied in this
Agreement, and notwithstanding the fact that certain of the Parties may be partnerships or limited liability companies, each Party covenants, agrees and acknowledges that no recourse under this Agreement or any documents or instruments delivered in

on, in respect of or by reason of such obligations or liabilities or their creation; provided, however, that nothing in this Section 10.14 shall relieve or otherwise limit the liability of any Party hereto or
any of their respective successors or permitted assigns for any breach or violation of its obligations under this Agreement or such other documents or instruments. For the avoidance of doubt, none of the Parties will have any recourse, be
entitled to commence any proceeding or make any claim under this Agreement or in connection with the transactions contemplated hereby except against any of the Parties or their respective successors and permitted assigns, as applicable. 

  
 64 

 Section 10.15 Relationship Among Parties. 

(a) Notwithstanding anything herein to the contrary, the duties and obligations of the Commitment Parties, on the one hand, and the Debtors,
on the other hand, arising under this Agreement shall be several, not joint. No Party shall have any responsibility by virtue of this Agreement for any trading by any other entity. No prior history, pattern, or practice of sharing confidences among
or between the Parties shall in any way affect or negate this Agreement. The Parties hereto acknowledge that this Agreement does not constitute an agreement, arrangement, or understanding with respect to acting together for the purpose of acquiring,
holding, voting, or disposing of any equity securities of the Debtors and the Commitment Parties do not constitute a “group” within the meaning of Rule 13d-5 under the Securities Exchange Act of
1934, as amended. Nothing contained herein or any Definitive Documentation and no action taken by any Commitment Party pursuant to this Agreement shall be deemed to constitute or to create a presumption by any parties that the Commitment Parties are
in any way acting in concert or as a “group” (or a joint venture, partnership or association), and the Debtors will not assert any such claim with respect to such obligations or the transactions contemplated by this Agreement or the
Definitive Documentation, and the Debtors acknowledge that neither the HoldCo Equityholders Commitment Parties nor the HoldCo Noteholder Commitment Parties are acting in concert or as a group with respect to such obligations or the transactions
contemplated by this Agreement or the Definitive Documentation. The Debtors acknowledge and each HoldCo Equityholder Commitment Party and each HoldCo Noteholder Commitment Party confirms that it has independently participated in the negotiation of
the transactions contemplated under this Agreement and the Definitive Documentation with the advice of counsel and advisors. 
 (b) In
connection with any matter requiring consent or a request of the Requisite Commitment Parties under this Agreement, there is no requirement or obligation that such holders agree among themselves to take such action and no agreement among such
holders with respect to any such action. In connection with any matter that may be requested by the Requisite Commitment Parties, each such holder may, through its counsel, make such request; provided, that the Company will only be required to take
such action if it receives the request of the Requisite Commitment Parties, as the case may be. In connection with any matter requiring consent of the Requisite Commitment Parties hereunder, the Company will solicit consent independently from each
such holder or its respective counsel; provided, that such consent shall only be granted if the approval of the Requisite Commitment Parties (as applicable) is obtained. 

(c) It is understood and agreed that none of the Commitment Parties has any duty of trust or confidence in any form with any other Commitment
Party, the Debtors, or any of the Debtors’ creditors or other stakeholders and, except as expressly provided in this Agreement, there are no agreements, commitments or undertakings by, among or between any of them with respect to the subject
matter hereof. For the avoidance of doubt, the foregoing sentence does not include any fiduciary obligations owed by any Plan Support Party that has been appointed an officer of any Debtor.

 Exhibit A 

Rights Offering Procedures 

 ULTRA PETROLEUM CORP. (THE “COMPANY”) 

RIGHTS OFFERING PROCEDURES1 

Each Rights Offering Share (as defined below) is being distributed and issued by the Company (i) pursuant to an effective registration statement under
the Securities Act of 1933, as amended (the “Securities Act”; such offering, a “Registered Rights Offering”), or (ii) without registration under the Securities Act, in reliance upon the exemption provided in
Section 1145 of the Bankruptcy Code (such offering, an “1145 Rights Offering”). None of the Subscription Rights (as defined below) or the Rights Offering Shares issuable upon exercise of such rights distributed pursuant to
these Rights Offering Procedures in reliance upon the exemption provided in Section 1145 of the Bankruptcy Code have been or will be registered under the Securities Act, nor any state or local law requiring registration for offer and sale of a
security. 
 If the Rights Offering is a Registered Rights Offering, the Subscription Rights will be immediately detachable and freely transferable
separately from HoldCo Notes or HoldCo Equity Interests, as applicable; provided however that the transferability of Subscription Rights held by an Affiliate (as that term is defined under Rule 144 promulgated under the Securities Act (“Rule
144”) of the Company may be subject to limitations on transferability under the Securities Act. 
 If the Rights Offering is an 1145 Rights
Offering, the Subscription Rights will not be detachable or transferable separately from HoldCo Notes or HoldCo Equity Interests, as applicable. Rather, the Subscription Rights together with the underlying HoldCo Notes or HoldCo Equity Interests
with respect to which such Subscription Rights were issued, will trade together as a unit, subject to such limitations, if any, that would be applicable to the transferability of the underlying HoldCo Notes or HoldCo Equity Interests; and, provided
further, that following the exercise of any Subscription Rights, the holder thereof shall be prohibited from transferring or assigning the HoldCo Notes or the HoldCo Equity Interests, as applicable, corresponding to such Subscription Rights until
the earlier of (i) termination of the Rights Offering and (ii) the revocation of exercise of the Subscription Rights to the extent permitted by these Rights Offering Procedures. 

The Disclosure Statement (as defined below) has previously been distributed in connection with the Debtors’ solicitation of votes to accept or reject
the Plan (as 
  

	1 	 Terms used and not defined herein shall have the meaning assigned to them in the Plan Support Agreement, dated
as of November 21, 2016 (including the terms and conditions set forth in the Plan Term Sheet attached as Exhibit A to the Plan Support Agreement (the “Plan Term Sheet”), the terms and conditions set forth in the Backstop
Commitment Agreement attached as Exhibit B to the Plan Support Agreement (the “Backstop Agreement”) and collectively, including all the other exhibits thereto, as may be amended, supplemented or otherwise modified from time to time,
the “Plan Support Agreement”)). 

 
defined below) and that document sets forth important information, including risk factors, that should be carefully read and considered by each Eligible Holder (as defined below) prior to making
a decision to participate in the Rights Offering (as defined below). Additional copies of the Disclosure Statement are available upon request from the Subscription Agent. 

The Rights Offering is being conducted by the Company in good faith and in compliance with the Bankruptcy Code. In accordance with Section 1125(e) of the
Bankruptcy Code, a debtor or any of its agents that participate, in good faith and in compliance with the applicable provisions of the Bankruptcy Code, in the offer, issuance, sale, or purchase of a security offered or sold under the plan of the
debtor, of an affiliate participating in a joint plan with the debtor, or of a newly organized successor to the debtor under the plan, is not liable, on account of such participation, for violation of any applicable law, rule, or regulation
governing the offer, issuance, sale or purchase of securities. 

 Eligible Holders (as defined below) should note the following times relating to the Rights Offering: 

 

					
	 Date
	  	 Calendar Date
	  	 Event

	Record Date	  	[●], 2016	  	The date and time fixed by the Company pursuant to the Plan for the determination of the holders eligible to receive Subscription Rights.
			
	Subscription Commencement Date	  	[●], 2017	  	Commencement of the Rights Offering.
			
	Subscription Expiration Deadline	  	4:00 p.m. Houston time on [●], 2017	  	 The deadline for Eligible Holders to subscribe for Rights Offering Shares. An Eligible Holder’s applicable Beneficial Holder
Subscription Form(s) (with accompanying IRS Form W-9 or appropriate IRS Form W-8, as applicable) must be received by the Eligible Holder’s Nominee (as defined
below) in sufficient time to allow such Nominee to deliver the Master Subscription Form to the Subscription Agent by the Subscription Expiration Deadline.
  

Eligible Holders who are not Commitment Parties must deliver the aggregate Purchase Price (as defined below) by the Subscription Expiration Deadline.

 
 Eligible Holders who are Commitment Parties must deliver the aggregate Purchase Price no
later than the deadline specified in the Funding Notice (as defined below) in accordance with the terms of the Backstop Agreement.

 To Eligible Holders and Nominees of Eligible Holders: 

On [●], 2016, the Debtors filed the Debtors’ Joint Chapter 11 Plan of Reorganization (as may be amended, modified, or
supplemented from time to time in accordance with the terms thereof, the “Plan”) with the United States Bankruptcy Court for the Southern District of Texas, Houston Division, and the Disclosure Statement for the Debtors’
Joint Chapter 11 Plan of Reorganization (as may be amended from time to time in accordance with its terms, the “Disclosure Statement”). Pursuant to the Plan, each Holder of an Allowed HoldCo Notes Claim (each such holder,
together with its permitted transferees, an “Eligible HoldCo Noteholder”) as of the Record Date shall receive HoldCo Noteholders Subscription Rights (as defined below) pursuant to the HoldCo Noteholders Rights Offering (as defined
below), and each Holder of an Allowed HoldCo Equity Interest (each such holder, together with its permitted transferees, an “Eligible HoldCo Equityholder” and, together with the Eligible HoldCo Noteholders, “Eligible
Holders”) as of the Record Date shall receive HoldCo Equityholders Subscription Rights (as defined below) pursuant to the HoldCo Equityholder Rights Offering (as defined below), in each case, in accordance with the terms and conditions of
these Rights Offering Procedures. The HoldCo Noteholders Rights Offering and the HoldCo Equityholders Rights Offering are collectively referred to herein as the “Rights Offering”. Notwithstanding anything to the contrary contained
herein, in the event that the Rights Offering is a Registered Rights Offering, the Subscription Rights shall be immediately detachable and trade separately from the underlying Allowed HoldCo Notes Claims and the Allowed HoldCo Equity Interests, as
applicable, and there shall be no limitation (except for those limitations imposed by applicable securities law, if any) on the person or persons that may exercise any of the rights transferred hereunder. For the avoidance of doubt, in such
circumstance, for purposes of determining who may exercise a Subscription Right, the terms “Eligible Holder,” “Eligible HoldCo Noteholder” and “Eligible HoldCo Equityholder” shall include any person that validly holds
the Subscription Right as of the date of exercise, without any requirement that such person hold a Noteholder Claim or Equityholder Interest as of such date. 

Pursuant to the Plan, each Eligible HoldCo Noteholder as of the Record Date will receive rights to subscribe for its pro rata portion
of 75 percent of the Shares (as defined below) offered in the Rights Offering (the “HoldCo Noteholders Rights Offering,” and such Shares, the “HoldCo Noteholders Rights Offering Shares”), which HoldCo
Noteholder Rights Offering Shares, collectively, will reflect an aggregate purchase price of $435,000,000 calculated by multiplying the number of Shares offered in the HoldCo Noteholder Rights Offering by the Purchase Price.
“Shares” shall be the fully diluted number of shares of Reorganized HoldCo before taking into account issuances of Shares pursuant to the management incentive plan to be adopted by the Company. “Purchase Price”
shall be the quotient of $2.7 billion divided by the Shares based on a Total Enterprise Value of the Debtors of $6.0 billion, subject to the adjustment provided in the definition of Purchase Price and Total Enterprise Value in the Backstop
Agreement. Each Nominee will receive a Master Subscription Form which it shall use to summarize the Subscription Rights exercised by each Eligible HoldCo Noteholder that timely returns the applicable properly filled out Beneficial Holder
Subscription Form(s) to such Nominee. Beneficial Holder Subscription Forms should only be returned directly to the 

 
Subscription Agent if the Eligible HoldCo Noteholder is the direct holder of record on the books of the applicable indenture trustee and does not hold its Allowed HoldCo Notes Claim through a
Nominee. 
 Pursuant to the Plan, each Eligible HoldCo Equityholder as of the Record Date will receive rights to subscribe for its pro
rata portion of 25 percent of the Shares offered in the Rights Offering (the “HoldCo Equityholders Rights Offering,” and such Shares, the “HoldCo Equityholders Rights Offering Shares” and, together with the
HoldCo Noteholders Rights Offering Shares, the “Rights Offering Shares”), which HoldCo Equityholder Rights Offering Shares, collectively, will reflect an aggregate purchase price of $145,000,000 calculated by multiplying the number
of Shares offered in the HoldCo Equityholder Rights Offering by the Purchase Price. Each Nominee will receive a Master Subscription Form which it shall use to summarize the Subscription Rights exercised by each Eligible HoldCo Equityholder that
timely returns the applicable properly filled out Beneficial Holder Subscription Form(s) to such Nominee. Beneficial Holder Subscription Forms should only be returned directly to the Subscription Agent if the Eligible HoldCo Equityholder is the
direct holder of record on the books of the applicable transfer agent and does not hold its HoldCo Equity Interests through a Nominee. 

Please note that all Beneficial Holder Subscription Forms (with accompanying IRS Form W-9 or
appropriate IRS Form W-8, as applicable) must be returned to the applicable Nominee in sufficient time to allow such Nominee to process and deliver the Master Subscription Form and copies of all Beneficial
Holder Subscription Forms, and the accompanying IRS Forms prior to the Subscription Expiration Deadline. To the extent of any discrepancy between the Master Subscription Form and the Beneficial Holder Subscription Form(s) regarding the Eligible
Holder’s principal amount, the Master Subscription Form shall govern. While the amount of time necessary for a Nominee to process and deliver the Master Subscription Form to the Subscription Agent will vary from Nominee to Nominee, Eligible
Holders are urged to consult with their Nominees to determine the necessary deadline to return their Beneficial Holder Subscription Forms. Failure to submit such Beneficial Holder Subscription Forms on a timely basis will result in forfeiture of an
Eligible Holder’s rights to participate in the Rights Offering. None of the Company, the Subscription Agent or any of the Commitment Parties will have any liability for any such failure. 

No Eligible Holder shall be entitled to participate in the Rights Offering unless the aggregate Purchase Price (as defined below) for the
Rights Offering Shares it subscribes for is received by the Subscription Agent (i) in the case of an Eligible Holder that is not a Commitment Party, by the Subscription Expiration Deadline, and (ii) in the case of an Eligible Holder that
is a Commitment Party, no later than the deadline specified in a written notice (a “Funding Notice”) delivered by or on behalf of the Debtors to the Commitment Parties in accordance with Section 2.4 of the Backstop Agreement
(the “Backstop Funding Deadline”), provided that the Commitment Parties may deposit their aggregate Purchase Price in the Escrow Account (as defined below), in accordance with the terms of the Backstop Agreement. No interest is
payable on any advanced funding of the Purchase Price. If the Rights Offering is terminated for any reason, the aggregate Purchase Price previously received by the Subscription Agent will be returned to Eligible Holders as provided in Section 6
hereof. No 

 
interest will be paid on any returned Purchase Price. Any Eligible Holder who is not a Commitment Party submitting payment via its Nominee must coordinate such payment with its Nominee in
sufficient time to allow the Nominee to forward such payment to the Subscription Agent by the Subscription Expiration Deadline. 
 To
participate in the Rights Offering, an Eligible Holder must complete all of the steps outlined below. If an Eligible Holder does not complete all of the steps outlined below by the Subscription Expiration Deadline or the Backstop Funding Deadline,
as applicable, such Eligible Holder shall be deemed to have forever and irrevocably relinquished and waived its right to participate in the Rights Offering. 
  

	 	1.	Rights Offering 

 Eligible HoldCo Noteholders have the right, but not the obligation, to
participate in the HoldCo Noteholders Rights Offering, and Eligible HoldCo Equityholders have the right, but not the obligation, to participate in the HoldCo Equityholders Rights Offering. 

Eligible HoldCo Noteholders as of the Record Date shall receive rights to subscribe for their pro rata portion of the HoldCo
Noteholders Rights Offering Shares, and Eligible HoldCo Equityholders as of the Record Date shall receive rights to subscribe for their pro rata portion of the HoldCo Equityholders Rights Offering Shares. 

Subject to the terms and conditions set forth in the Plan and these Rights Offering Procedures, each Eligible HoldCo Noteholder as of the
Record Date is entitled to receive rights to subscribe for up to [●] HoldCo Noteholders Rights Offering Shares per $1,000 of Principal Amount of 5.75% Senior Notes Due 2018 issued by the Company and up to [●] HoldCo Noteholders Rights
Offering Shares per $1,000 of Principal Amount of 6.125% Senior Notes Due 2024 issued by Company at the Purchase Price. The difference in the number of Rights Offering Shares that an Eligible HoldCo Noteholder is entitled to subscribe for with
respect to each series of HoldCo Notes is to take into account the differing amounts, as of the Record Date, of pre-petition accrued and unpaid interest thereon. 

Subject to the terms and conditions set forth in the Plan and these Rights Offering Procedures, each Eligible HoldCo Equityholder as of the
Record Date is entitled to receive rights to subscribe for up to [●] HoldCo Equityholders Rights Offering Shares per HoldCo Equity Interest at the Purchase Price. 

There will be no over-subscription privilege in the Rights Offering. Any Rights Offering Shares that are unsubscribed by the Eligible Holders
entitled thereto will not be offered to other Eligible Holders but will be purchased by the applicable Commitment Parties in accordance with the Backstop Agreement. Subject to the terms and conditions of the Backstop Agreement, each Commitment Party
is obligated to purchase its pro rata portion of the applicable Rights Offering Shares. 
 To the extent the Rights Offering Shares
are distributed and issued without registration under the Securities Act, in reliance upon the exemption provided in Section 1145 of the Bankruptcy Code, any Eligible Holder that subscribes for Rights Offering Shares and is deemed

 
to be an “underwriter” under Section 1145(b) of the Bankruptcy Code will be subject to restrictions under the Securities Act on its ability to resell those securities. Resale
restrictions are discussed in more detail in Article [●] of the Disclosure Statement, entitled “Certain Securities Law Matters.” 

To the extent the Rights Offering Shares are distributed and issued with registration under the Securities Act, any Eligible Holder that
subscribes for Rights Offering Shares and is deemed to be an “affiliate” under Rule 144 may be subject to restrictions under Rule 144 on its ability to resell those securities. Resale restrictions are discussed in more detail in Article
[●] of the Disclosure Statement, entitled “Certain Securities Law Matters.” 
 SUBJECT
TO THE TERMS AND CONDITIONS OF THE RIGHTS OFFERING PROCEDURES AND THE BACKSTOP AGREEMENT IN THE CASE OF ANY COMMITMENT PARTY, ALL SUBSCRIPTIONS SET FORTH IN THE APPLICABLE BENEFICIAL HOLDER SUBSCRIPTION FORM(S) ARE IRREVOCABLE. 

 

	 	2.	Subscription Period 

 The Rights Offering will commence on the Subscription Commencement
Date and will expire at the Subscription Expiration Deadline. Each Eligible Holder intending to purchase Rights Offering Shares in any Rights Offering must affirmatively elect to exercise its Subscription Rights in the manner set forth in the
applicable Subscription Form by the Subscription Expiration Deadline. 
 Any exercise of the subscription rights to purchase HoldCo
Noteholders Rights Offering Shares (the “HoldCo Noteholders Subscription Rights”) by an Eligible HoldCo Noteholder after the Subscription Expiration Deadline will not be allowed and any purported exercise received by the
Subscription Agent after the Subscription Expiration Deadline, regardless of when the documents or payment relating to such exercise were sent, will not be honored, except that the Company shall have the discretion, with the consent of the Holdco
Noteholder Commitment Parties holding at least sixty-six and two-thirds percent (66-2/3%) of all outstanding HoldCo Noteholders
Backstop Commitments at the time of the relevant determination (the “HoldCo Noteholder Requisite Commitment Parties”), to allow any exercise of HoldCo Noteholders Subscription Rights after the Subscription Expiration Deadline. 

Any exercise of the subscription rights to purchase HoldCo Equityholders Rights Offering Shares (the “HoldCo Equityholders
Subscription Rights” and, together with the HoldCo Noteholders Subscription Rights, the “Subscription Rights”) by an Eligible HoldCo Equityholder after the Subscription Expiration Deadline will not be allowed and any
purported exercise received by the Subscription Agent after the Subscription Expiration Deadline, regardless of when the documents or payment relating to such exercise were sent, will not be honored, except that the Company shall have the
discretion, with the consent of the Holdco Equityholder Commitment Parties holding at least sixty-six and two-thirds percent
(66-2/3%) of all outstanding HoldCo Equityholders Backstop Commitments at the time of the relevant determination (the “HoldCo Equityholder Requisite Commitment Parties” and together with the
HoldCo Noteholder Requisite Commitment Parties, the “Requisite Commitment Parties”), to allow any exercise of HoldCo Equityholders Subscription Rights after the Subscription Expiration Deadline. 

 The Subscription Expiration Deadline may be extended with the consent of the Requisite Commitment
Parties, or as required by law. 
  

	 	3.	Delivery of Subscription Documents 

 Each Eligible Holder may exercise all or any portion
of such Eligible Holder’s Subscription Rights, but subject to the terms and conditions contained herein. In order to facilitate the exercise of the Subscription Rights, beginning on the Subscription Commencement Date, the applicable
Subscription Form and these Rights Offering Procedures will be sent to each Eligible Holder, together with appropriate instructions for the proper completion, due execution and timely delivery of the executed Subscription Form and the payment of the
applicable aggregate Purchase Price for its Rights Offering Shares. 
  

	 	4.	Exercise of Subscription Rights 

 (a) In order to validly exercise its Subscription
Rights, each Eligible Holder that is not a Commitment Party must: 
  

	 	i.	return duly completed and executed applicable Beneficial Holder Subscription Form(s) (with accompanying IRS Form W-9 or appropriate IRS Form
W-8, as applicable) to the Subscription Agent or its Nominee, as applicable, so that, if applicable, such documents may be transmitted to the Subscription Agent by the Nominee, so that such documents are
actually received by the Subscription Agent by the Subscription Expiration Deadline; and 

  

	 	ii.	at the same time it returns its Beneficial Holder Subscription Form(s) to its Nominee, but in no event later than the Subscription Expiration Deadline, pay, or arrange for the payment by its Nominee of, the applicable
Purchase Price to the Subscription Agent by wire transfer ONLY of immediately available funds in accordance with the instructions included in the applicable Beneficial Holder Subscription Form(s). 

(b) In order to validly exercise its Subscription Rights, each Eligible Holder that is a Commitment Party must: 

 

	 	i.	return duly completed and executed applicable Beneficial Holder Subscription Form(s) (with accompanying IRS Form W-9 or appropriate IRS Form
W-8, as applicable) to the Subscription Agent or its Nominee, as applicable so that, if applicable, such documents may be transmitted to the Subscription Agent by the Nominee, so that such documents are
actually received by the Subscription Agent by the Subscription Expiration Deadline; and 

  

	 	ii.	no later than the Backstop Funding Deadline, pay the applicable Purchase Price to the Subscription Agent or to the escrow account established and maintained by a third party satisfactory to the Commitment Parties and
the Company (the “Escrow Account”) by wire transfer ONLY of immediately available funds in accordance with the wire instructions included in the Funding Notice. 

 ALL COMMITMENT PARTIES MUST PAY THEIR APPLICABLE PURCHASE PRICE DIRECTLY TO THE SUBSCRIPTION AGENT OR TO THE
ESCROW ACCOUNT, AS APPLICABLE, AND SHOULD NOT PAY THEIR NOMINEE(S). 
  

	 	(c)	With respect to 4(a) and (b) above, each Eligible Holder must duly complete, execute and return the applicable Beneficial Holder Subscription Form(s) in accordance with the instructions herein to its Nominee in
sufficient time to allow its Nominee to process its instructions and deliver to the Subscription Agent the Master Subscription Form, its completed Beneficial Holder Subscription Form(s) (with accompanying IRS Form
W-9 or appropriate IRS Form W-8, as applicable), and, solely with respect to the Eligible Holders that are not Commitment Parties, payment of the applicable Purchase
Price, payable for the Rights Offering Shares elected to be purchased by such Eligible Holder, by the Subscription Expiration Deadline. Eligible Holders that are Commitment Parties must deliver their payment of the applicable Purchase Price payable
for the Rights Offering Shares elected to be purchased by such Commitment Party directly to the Subscription Agent or to the Escrow Account, as applicable, no later than the Backstop Funding Deadline. 

 

	 	(d)	In the event that the funds received by the Subscription Agent or the Escrow Account, as applicable, from any Eligible Holder do not correspond to the Purchase Price payable for the Rights Offering Shares elected to be
purchased by such Eligible Holder, the number of the Rights Offering Shares deemed to be purchased by such Eligible Holder will be the lesser of (a) the number of the Rights Offering Shares elected to be purchased by such Eligible Holder and
(b) a number of the Rights Offering Shares determined by dividing the amount of the funds received by the Purchase Price, in each case up to such Eligible Holder’s pro rata portion of Rights Offering Shares. 

 

	 	(e)	The cash paid to the Subscription Agent in accordance with these Rights Offering Procedures will be deposited and held by the Subscription Agent in a segregated account until released to the Debtors in connection with
the settlement of the Rights Offering on the Effective Date. The Subscription Agent may not use such cash for any other purpose prior to the Effective Date and may not encumber or permit such cash to be encumbered with any lien or similar
encumbrance. The cash held by the Subscription Agent hereunder shall not be deemed part of the Debtors’ bankruptcy estates. 

	 	5.	Transfer Restriction; Revocation 

 If the Rights Offering is an 1145 Rights Offering:

  

	 	•	 	The Subscription Rights will not be detachable or transferable separately from HoldCo Notes or HoldCo Equity Interests, as applicable. If any Subscription Rights are transferred by an Eligible Holder in contravention of
the foregoing, the Subscription Rights will be cancelled, and neither such Eligible Holder nor the purported transferee will receive any Rights Offering Shares otherwise purchasable on account of such transferred Subscription Rights;

  

	 	•	 	The Subscription Rights together with the underlying HoldCo Notes or HoldCo Equity Interests with respect to which such Subscription Rights were issued, will trade together as a unit, subject to such limitations, if
any, that would be applicable to the transferability of the underlying HoldCo Notes or HoldCo Equity Interests; and 

  

	 	•	 	Once an Eligible Holder has properly exercised its Subscription Rights, subject to the terms and conditions contained in these Rights Offering Procedures and the Backstop Agreement in the case of any Commitment Party,
such exercise will be irrevocable. Moreover, following the exercise of any Subscription Rights, the holder thereof shall be prohibited from transferring or assigning the HoldCo Notes or the HoldCo Equity Interests, as applicable, corresponding to
such Subscription Rights until the earlier of (i) termination of the Rights Offering and (ii) the revocation of exercise of the Rights to the extent permitted by these Rights Offering Procedures. 

If the Rights Offering is a Registered Rights Offering: 
  

	 	•	 	the Subscription Rights will immediately be detachable from the HoldCo Notes or the HoldCo Equity Interests with respect to which they were distributed, as applicable, and trade separately from any such claims or
interests, and nothing in these Rights Offering Procedures should limit the separate transferability of HoldCo Notes or HoldCo Equity Interests. 

  

	 	6.	Termination/Return of Payment 

 Unless the Effective Date has occurred, the Rights
Offering will be deemed automatically terminated without any action of any party upon the earlier of (i) termination of the Plan Support Agreement in accordance with its terms, (ii) termination of the Backstop Agreement in accordance with
its terms and (iii) the Outside Date (as such date may be extended pursuant to the terms of the Backstop Agreement). In the event the Rights Offering is terminated, any payments received pursuant to these Rights Offering Procedures will be
returned, without interest, to the applicable Eligible Holder as soon as reasonably practicable. 
  

	 	7.	Settlement of the Rights Offering and Distribution of the Rights Offering Shares 

 The
settlement of the Rights Offering is conditioned on confirmation of the Plan by the Bankruptcy Court, compliance by the Debtors with these Rights Offering Procedures, and the 

 
simultaneous occurrence of the Effective Date. The Debtors intend that the Rights Offering Shares will be issued to the Eligible Holders and/or to any party that an Eligible Holder so designates
in the Beneficial Holder Subscription Form(s), in book-entry form, and that The Depository Trust Company (“DTC”), or its nominee, will be the holder of record of such Rights Offering Shares. To the extent DTC is unwilling or unable
to make the Rights Offering Shares eligible on the DTC system, the Rights Offering Shares will be issued directly to the Eligible Holder or its designee. 
  

	 	8.	Fractional Shares 

 No fractional rights or Rights Offering Shares will be issued in the
Rights Offering. All share allocations (including each Eligible Holder’s Rights Offering Shares) will be calculated and rounded down to the nearest whole share. 
  

	 	9.	Validity of Exercise of Subscription Rights 

 All questions concerning the timeliness,
viability, form and eligibility of any exercise of Subscription Rights will be determined in good faith by the Debtors in consultation with the Requisite Commitment Parties, and, if necessary, subject to a final and binding determination by the
Bankruptcy Court. The Debtor, with the consent of the Requisite Commitment Parties, may waive or reject any defect or irregularity in, or permit such defect or irregularity to be corrected within such time as they may determine in good faith, the
purported exercise of any Subscription Rights. Subscription Forms will be deemed not to have been received or accepted until all irregularities have been waived or cured within such time as the Debtors determine in good faith in consultation with
the Requisite Commitment Parties. 
 Before exercising any Subscription Rights, Eligible Holders should read the Disclosure Statement and
the Plan for information relating to the Debtors and the risk factors to be considered. 
 All calculations, including, to the extent
applicable, the calculation of (a)(i) the value of any Eligible HoldCo Noteholder’s Allowed HoldCo Notes Claim for the purposes of the HoldCo Noteholders Rights Offering and (ii) any Eligible HoldCo Noteholder’s HoldCo Noteholders
Rights Offering Shares, shall be made in good faith by the Company with the consent of the HoldCo Noteholders Requisite Commitment Parties and (b)(i) the value of any Eligible HoldCo Equityholders’ HoldCo Equity Interests for the purposes of
the HoldCo Equityholders Rights Offering and (ii) any Eligible HoldCo Equityholders’ HoldCo Equityholders Rights Offering Shares, shall be made in good faith by the Company with the consent of the HoldCo Equityholders Requisite Commitment
Parties and in each case in accordance with any claim amounts included in the Plan, and any disputes regarding such calculations shall be subject to a final and binding determination by the Bankruptcy Court. 

 

	 	10.	Modification of Procedures 

 With the prior written consent of the Requisite Commitment
Parties, the Debtors reserve the right to modify these Rights Offering Procedures, or adopt additional procedures consistent 

 
with these Rights Offering Procedures to effectuate the Rights Offering and to issue the Rights Offering Shares, provided, however, that the Debtors shall provide prompt written notice to each
Eligible Holder of any material modification to these Rights Offering Procedures made after the Subscription Commencement Date, provided further that any amendments or modifications to the terms of the Rights Offering are subject to the provisions
of Section 10.7 of the Backstop Agreement. In so doing, and subject to the consent of the Requisite Commitment Parties, the Debtors may execute and enter into agreements and take further action that the Debtors determine in good faith is
necessary and appropriate to effectuate and implement the Rights Offering and the issuance of the Rights Offering Shares. 
 To the extent
applicable, the Debtors shall undertake reasonable procedures to confirm that each participant in the Rights Offering is in fact an Eligible Holder. 
  

	 	11.	Depository Trust Company (“DTC”) 

 Some or all of the Allowed HoldCo Notes
Claims and the Allowed HoldCo Equity Interests are held in book-entry form in accordance with the practices and procedures of the DTC. The Debtors intend to comply with the practices and procedures of DTC for the purpose of conducting the Rights
Offering, and, subject to compliance with Section 11 hereof, these Rights Offering Procedures will be deemed appropriately modified to achieve such compliance. 

Without limiting the foregoing the Company intends, that to the extent practicable, the Rights Offering Shares will be issued in book entry
form, except with respect to persons that may be deemed underwriters under section 1145(b) of the Bankruptcy Code, and that DTC, or its nominee, will be the holder of record of such Rights Offering Shares. The ownership interest of each holder of
such Rights Offering Shares, and transfers of ownership interests therein, will be recorded on the records of the direct and indirect participants in DTC. Holders who exercise the Subscription Rights may be required to furnish the Company or its
agents information regarding their broker, bank or other securities nominee in order that the Rights Offering Shares for which they have subscribed can be properly credited to their securities account. To the extent required, the Company intends to
solicit such information on a timely basis, so that the Rights Offering Shares may be delivered to the holders exercising their Subscription Rights on or as promptly as practicable after the Effective Date. 

 

	 	12.	Inquiries And Transmittal of Documents; Subscription Agent 

 The Rights Offering
Instructions for Eligible Holders attached hereto should be carefully read and strictly followed by the Eligible Holders. 
 Questions
relating to the Rights Offering should be directed to the Subscription Agent via email to [[[●] (please reference “Subscription Rights Offering” in the subject line) or at the following phone number: [●]]. 

The risk of non-delivery of all documents and payments to the Subscription Agent, the Escrow Account
and any Nominee is on the Eligible Holder electing to exercise its Subscription Rights and not the Debtors, the Subscription Agent, or the Commitment Parties. 

 ULTRA PETROLEUM CORP.

and Hearing Procedures For Certain Transfers of and Declarations of Worthlessness with Respect to Common Stock entered by the Bankruptcy Court on June 13, 2016 [Docket No. 297] (the “NOL Order”).

 The following procedures (the “Procedures”) shall govern transfers of HoldCo Equity Interests by holders of
such HoldCo Equity Interests in over-the-counter transactions in accordance with the Plan Support Agreement (each, an “OTC Transfer”). Certain
capitalized terms used but not defined herein have the meanings set forth in the Plan Support Agreement. 
 1. Each Consenting HoldCo
Equityholder wishing to sell HoldCo Equity Interests pursuant to an OTC Transfer will notify such holder’s broker-dealer of its intention to sell such HoldCo Equity Interests and that such Consenting HoldCo Equityholder is a party to and bound
by the Plan Support Agreement. 
 2. Such broker-dealer will: (i) verbally notify each prospective purchaser of HoldCo Equity Interests
(each an “OTC Transferee”) or its broker-dealer that (A) the HoldCo Equity Interests being sold by the Consenting HoldCo Equityholder are subject to the jurisdiction of the Bankruptcy Court, the NOL Order, and the Plan Support
Agreement, (B) such OTC Transferee will become a party to, and be bound by the terms of, the Plan Support Agreement pursuant to a Transferee Joinder upon settlement of such OTC Transfer, (C) all HoldCo Equity Interests held by such OTC
Transferee, whether previously acquired, acquired pursuant to an OTC Transfer, as contemplated by these Procedures, or any other subsequent transaction with a third-party not party to the Plan Support Agreement, will be subject to the Plan Support
Agreement and these Procedures, and (D) any OTC Transfer of HoldCo Equity Interests sold by the Consenting HoldCo Equityholder shall be immediately revoked and void ab initio unless such OTC Transfer complies with these Procedures; and
(ii) direct such OTC Transferee to the website of HoldCo’s claims and noticing agent, Epiq Systems, at http://dm.epiq11.com/UPT, to view copies of the Plan Support Agreement and Form of Transferee Joinder and (iii) provide to
any market maker and/or purchaser broker-dealer the following legend to be included in the trade confirmation statement or any other similar record effectuating settlement of such OTC Transfer: “The common equity interests of Ultra Petroleum
Corp. (OTC: UPLMQ) transferred in connection with this transaction are subject to a Plan Support Agreement effective in connection with the pending cases of the Ultra Entities under chapter 11 of the Bankruptcy Code.” 

3. Written confirmation that an OTC Transferee is a party to, and is bound by the terms of, the Plan Support Agreement will be reflected in,
and immediately effective pursuant to, the trade confirmation statement or any other similar record effectuating settlement of such OTC Transfer. 

4. Each Consenting HoldCo Equityholder executing an OTC Transfer or their respective broker-dealer will notify HoldCo of such OTC Transfer and
provide the (i) relevant identifying information of the OTC Transferee and (ii) amount of HoldCo Equity Interests transferred to such OTC Transferee within two (2) business days of settlement of such OTC Transfer. 

5. Each OTC Transferee executing a subsequent OTC Transfer will be obligated to comply with these Procedures as though such OTC Transferee was
a Consenting HoldCo Equityholder. 

 6. Each Consenting HoldCo Equityholder, OTC Transferee and any subsequent OTC Transferee, by
consummating any OTC Transfer, acknowledges and agrees that any OTC Transfer consummated in contravention of these Procedures will constitute a breach of the Plan Support Agreement.EX-10.2

are, or are Affiliated with, a HoldCo Noteholders Commitment Party (other than any Defaulting Commitment Party) shall have the right, but not the obligation, within three (3) Business Days after receipt of written notice from the Company to all
HoldCo Noteholders Commitment Parties of such HoldCo Noteholders Commitment Party Default, which notice shall be given promptly following the occurrence of such HoldCo Noteholders Commitment Party Default and to all HoldCo Noteholders Commitment

by all of the HoldCo Noteholders Commitment Parties electing to purchase all or any portion of the HoldCo Noteholders Available Shares, or, if no such agreement is reached, based upon the relative applicable HoldCo Noteholders Backstop Commitment
Percentages of any such HoldCo Noteholders Commitment Parties that are, or are Affiliated with, a HoldCo Noteholders Commitment Party (other than any Defaulting Commitment Party) (such Commitment Parties, and any HoldCo Equityholders Commitment
Parties that purchase HoldCo Noteholders Available Shares pursuant to the last sentence of this paragraph, the “HoldCo Noteholders Replacing Commitment Parties”). In the event the HoldCo Noteholders Commitment Parties (or
their applicable affiliates) do not elect to purchase all of the HoldCo Noteholders Available Shares pursuant to the foregoing provisions of this paragraph, the Company shall give prompt written notice thereof to each of the HoldCo Equityholders
Commitment Parties, and such HoldCo Equityholders Commitment Parties shall have the right, but not the obligation, to purchase all or any portion of the remaining HoldCo Noteholders Available Shares on the same terms and conditions as if they were
HoldCo Equityholders Available Shares under Section 2.3(b) within three (3) Business Days of receiving notice from the Company. 

(b) Upon the occurrence of a HoldCo Equityholders Commitment Party Default, the HoldCo Equityholders Commitment Parties that are, or are

HoldCo Equityholders Commitment Party (other than any Defaulting Commitment Party) shall have the right, but not the obligation, within three (3) Business Days after receipt of written
notice from the Company to all HoldCo Equityholders Commitment Parties of such HoldCo Equityholders Commitment Party Default, which notice shall be given promptly following the occurrence of such HoldCo Equityholders Commitment Party Default and to
all HoldCo Equityholders Commitment Parties concurrently (such three (3) Business Day period, the “HoldCo Equityholders Commitment Party Replacement Period” and, together with the HoldCo Noteholders Commitment Party
Replacement Period, the “Commitment Party Replacement Period”), to make arrangements for one or more of the HoldCo Equityholders Commitment Parties that is, or is Affiliated with, a HoldCo Equityholders Commitment Party
(other than any Defaulting Commitment Party) to purchase all or any portion of the HoldCo Equityholders Available Shares (any such purchase, and any purchase by HoldCo Noteholders Commitment Parties pursuant to the last sentence of this paragraph, a
“HoldCo Equityholders Commitment Party Replacement” and, together with the HoldCo Noteholders Commitment Party Replacement and any purchase of Available Shares pursuant to Section 2.3(c), the “Commitment
Party Replacement”) 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 HoldCo Equityholders Commitment Parties electing to purchase all or any portion of the
HoldCo Equityholders Available Shares, or, if no such agreement is reached, based upon the relative applicable HoldCo Equityholders Backstop Commitment Percentages of any such HoldCo Equityholders Commitment Parties that are, or are Affiliated with,
a HoldCo Equityholders Commitment Party (other than the Defaulting Commitment Party) (such Commitment Parties, and any HoldCo Noteholders Commitment Parties that purchase HoldCo Equityholders Available Shares pursuant to the last sentence of this
paragraph, the “HoldCo Equityholders Replacing Commitment Parties” and, together with the HoldCo Noteholders Replacing Commitment Parties and any Commitment Party that purchases Available Shares pursuant to Section
2.3(c), the “Replacing Commitment Parties”). In the event the HoldCo Equityholders Commitment Parties (or their applicable affiliates) do not elect to purchase all of the HoldCo Equityholders Available Shares pursuant to
the foregoing provisions of this paragraph, the Company shall give prompt written notice thereof to each of the HoldCo Noteholders Commitment Parties, and such HoldCo Noteholders Commitment Parties shall have the right, but not the obligation, to
purchase all or any portion of the remaining HoldCo Equityholders Available Shares on the same terms and conditions as if they were HoldCo Noteholders Available Shares under Section 2.3(a) within three (3) Business Days of receiving
notice from the Company. 
 (c) [Reserved]. 

(d) In the event that any Commitment Parties do not elect to purchase all Available Shares available for purchase pursuant to Section
2.3(a) and Section 2.3(b), the Company may, in its sole discretion, elect to utilize the Cover Transaction Period to consummate a Cover Transaction. As used herein, “Cover Transaction” means a circumstance in
which the Company arranges for the sale of all or any portion of the Available Shares to any other Person, on the terms and subject to the conditions set forth in this Agreement, during the Cover Transaction Period, and “Cover Transaction
Period” means the ten (10) Business Day period following expiration of the three (3) Business Day period specified in the last sentence of Section 2.3(a) and Section 2.3(b), as applicable. For the avoidance of
doubt, the Company’s election to pursue a Cover Transaction, whether or not consummated, shall not relieve any Commitment Party of its obligation to fulfill its Backstop Commitment. 

  
 20 

 (e) Any Available Shares purchased by a Replacing Commitment Party (and any commitment and
applicable aggregate Per Share Purchase Price associated therewith) shall be included, among other things, in the determination of (x) the HoldCo Noteholders Unsubscribed Shares or HoldCo Equityholders Unsubscribed Shares of such HoldCo
Noteholders Replacing Commitment Party or HoldCo Equityholders Replacing Commitment Party, respectively, for all purposes hereunder, (y) the Backstop Commitment Percentage of such Replacing Commitment Party for purposes of Section
2.3(g), Section 2.4(b), Section 3.1 and Section 3.2 and (z) the Backstop Commitment of such Replacing Commitment Party for purposes of the definition of “Requisite Commitment
Parties.” If a Commitment Party Default occurs, the Outside Date shall be delayed only to the extent necessary to allow for (i) the Commitment Party Replacement to be completed within the Commitment Party Replacement Period and/or (ii), if
applicable, the Cover Transaction to be completed within the Cover Transaction Period. 
 (f) If a Commitment Party is a Defaulting
Commitment Party, it shall not be entitled to any of the Commitment Premium hereunder. Any portion of the Commitment Premium otherwise payable to any Defaulting Commitment Party except for such Commitment Party Default shall be paid pro-rata to any Replacing Commitment Party. 
 (g) Nothing in this Agreement shall be deemed to require a
Commitment Party to purchase more than its Backstop Commitment Percentage of the Unsubscribed Shares. 
 (h) For the avoidance of doubt,
notwithstanding anything to the contrary set forth in Section 9.4 but subject to Section 10.10, no provision of this Agreement shall relieve any Defaulting Commitment Party from liability
hereunder, or limit the availability of the remedies set forth in Section 10.9, in connection with any such Defaulting Commitment Party’s Commitment Party Default. 

Section 2.4 Escrow Account Funding.

Price for such Commitment Party’s HoldCo Noteholders Backstop Commitment Percentage and/or HoldCo Equityholders Backstop Commitment Percentage of the HoldCo Noteholders Unsubscribed Shares and/or HoldCo Equityholders Unsubscribed Shares, as

Offering Expiration Time pursuant to the Rights Offerings, by wire transfer of immediately available funds in U.S. dollars into the Escrow Account in satisfaction of such Commitment Party’s Backstop Commitment and its obligation to fully
exercise its Subscription Rights; provided, that in no event shall the Escrow Account Funding Date be less than four (4) Business Days after the Funding Notice Date or more than five (5) Business Days prior to the Effective Date.
Notwithstanding the foregoing, all payments contemplated to be made by any Commitment Party to the Escrow Account pursuant to this Section 2.4 may instead be made, at the option of such Commitment Party, to a segregated
bank account of the Rights Offering Subscription Agent designated by the Rights Offering Subscription Agent in the Funding Notice and shall be delivered and paid to such account on the Escrow Account Funding Date.

Commitment Party pursuant to the Reorganized Company’s book entry procedures and delivery to such Commitment Party of an account statement reflecting the book entry of such Unsubscribed Shares and Available Shares shall be deemed delivery of
such Unsubscribed Shares and Available Shares for purposes of this Agreement. Notwithstanding anything to the contrary in this Agreement, all Unsubscribed Shares and Available Shares will be delivered with all issue, stamp, transfer, sales and use,
or similar transfer Taxes or duties that are due and payable (if any) in connection with such delivery duly paid by the Company on behalf of the Reorganized Company. 

Section 2.6 Designation and Assignment Rights.

signed by such Commitment Party and each such Related Purchaser, (ii) specify the number of Unsubscribed Shares to be delivered to or issued in the name of such Related Purchaser and (iii) contain a confirmation by each such Related

 (b) Commitment Parties shall not be entitled to
Transfer all or any portion of their Backstop Commitments except as expressly provided in this Section 2.6. Each Commitment Party shall have the right to Transfer all or any portion of its Backstop Commitment to: (i) an Affiliated Fund;
(ii) one or more special purpose vehicles that are wholly owned by one or more of such Commitment Party and its Affiliated Funds, created for the purpose of holding such Backstop Commitment or holding debt or equity of the Company; provided,

 23 

 
Party’s Affiliated Fund, such other Commitment Party, either (A) shall have provided an adequate equity support letter or a guarantee of such special purpose vehicle’s Backstop
Commitment in form and substance reasonably acceptable to the Company or (B) shall remain (or in the case of a transfer to another Commitment Party’s Affiliated Fund, such other Commitment Party, shall become) obligated to fund such
Backstop Commitment; provided, further that such special purpose vehicle shall not be related to or Affiliated with any portfolio company of such Commitment Party or any of its Affiliates or Affiliated Funds (other than solely by virtue of its
affiliation with such Commitment Party) and the equity of such special purpose vehicle shall not be directly or indirectly transferable other than to such Persons described in clauses (i) or (ii) of this Section 2.6(b), and in such
manner as such Commitment Party’s Backstop Commitment is transferable pursuant to this Section 2.6(b); or (iii) any other Commitment Party, including an Additional Commitment Party; (each of the Persons referred to in clauses (i),
(ii) and (iii) above, an “Ultimate Purchaser”). In each case of a Commitment Party’s Transfer of all or any portion of its Backstop Commitment pursuant to this Section 2.6(b), (1) the Ultimate Purchaser shall
have provided a written agreement to the Company and counsel to the Commitment Parties under which it (w) confirms that it is an “accredited investor” within the meaning of Rule 501(a) of the Securities Act or the accuracy of the
representations set forth in Section 5.8 herein as applied to such Ultimate Purchaser, (x) agrees to purchase such portion of such Commitment Party’s Backstop Commitment, (y) agrees to be fully bound by, and
subject to, this Agreement as a Commitment Party hereto pursuant to a joinder agreement in the form set forth on Exhibit C and (z) agrees to be bound by the Plan Support Agreement pursuant to a transfer agreement in the form set forth on
Exhibit D, and (2) the transferring Commitment Party and the Ultimate Purchaser shall have duly executed and delivered to the Company, Paul, Weiss, Rifkind, Wharton & Garrison LLP and Brown Rudnick, LLP, as applicable (at the addresses
set forth in Section 10.1), written notice of such Transfer; provided, however, that, except in the case of (iii) above, or in the case of a transfer to another Commitment Party’s Affiliated Fund in accordance
with the foregoing, no such Transfer shall relieve the transferring Commitment Party from any of its obligations under this Agreement. 

(c) In addition to Transfers pursuant to the preceding paragraph, each Commitment Party shall have the right to Transfer, directly or
indirectly, all or any portion of its Backstop Commitment to any other entity; provided, that (i) with respect any such Transfer of a Backstop Commitment to a single transferee, the amount of such Backstop Commitment, as compared to the
aggregate Backstop Commitment of all Commitment Parties (the “Aggregate Backstop Commitment Percentage”) is no less than 0.2%, or all of the Backstop Commitment of such Commitment Party or the Backstop Commitment of any fund
or account on behalf of which such Commitment Party is acting if such Commitment Party, fund or account holds a Backstop Commitment representing less than 0.2% of the Aggregate Backstop Commitment Percentage of all Commitment Parties, (ii) with
respect to any transferee that is not a Commitment Party, such transferee agrees, pursuant to a joinder agreement in the form set forth on Exhibit C, to be bound by the obligations of such Commitment Party under this Agreement, and each of
such Commitment Party, such transferee and the Company shall have duly executed and delivered to each other a copy of such joinder agreement, and (iii) with respect to any transferee that is a Commitment Party, such transferee and the
transferring Commitment Party shall have duly executed and delivered to the Debtors written notice of such Transfer in form and substance reasonably acceptable to the Debtors, and the Debtors shall have delivered countersigned copies of such notice
to such transferee and the transferring Commitment Party 

  
 24 

 
and to counsel to the Commitment Parties; provided, further, that the transfer to any such transferee who is not a Commitment Party shall be on five (5) Business Days’
notice to the Company and shall be effective unless the Company delivers a written objection to the transferring Commitment Party within such period, setting forth reasonable grounds for such objection. Upon compliance with this paragraph, the
transferring Commitment Party shall be deemed to relinquish its rights (and be released from its obligations, except for any claim for breach of this Agreement that occurs prior to such Transfer) under this Agreement to the extent of such
transferred rights and obligations, and the transferee shall be fully bound as a Commitment Party hereunder for all purposes of this Agreement. Any Transfer made in violation of this paragraph shall be deemed null and void ab initio and of no force
or effect, regardless of any prior notice provided to the Debtors or any Commitment Party, and shall not create any obligation or liability of any Debtor or any other Commitment Party to the purported transferee. Upon the effectiveness of any
Transfer of all or a portion of a Backstop Commitment pursuant to this Section 2.6, the Company shall update Schedule IA and/or Schedule IB hereto, as applicable, to reflect such Transfer, and such updates shall not
constitute an amendment to this Agreement. The Company shall provide a copy of any such Transfer notice, Joinder Agreement or other agreement entered into in connection with any Transfers pursuant to this Section 2.6,
together with any updates to Schedules IA and/or IB hereto, to counsel to the Commitment Parties promptly, and in any event within one (1) Business Day following receipt by the Company of any such agreement or notice or the date of any such
update, as applicable. 
 (d) Each Commitment Party, severally and not jointly, agrees that it will not Transfer, at any time prior to the
Closing Date or the earlier termination of this Agreement in accordance with its terms, any of its rights and obligations under this Agreement to any Person other than in accordance with Section 2.6(a), Section 2.6(b) or Section
2.6(c), as applicable. After the Closing Date, nothing in this Agreement shall limit or restrict in any way the ability of any Commitment Party (or any permitted transferee thereof) to Transfer any of the Common Shares or any interest therein;
provided, that any such Transfer shall be made pursuant to an effective registration statement under the Securities Act or an exemption from the registration requirements thereunder and pursuant to applicable securities Laws. For the
avoidance of doubt, notwithstanding anything to the contrary in this Agreement, nothing contained in this Agreement shall prohibit or restrict the ability of any Commitment Party to Transfer its HoldCo Notes and/or HoldCo Noteholders Subscription
Rights or Equity Interests and/or HoldCo Equityholders Subscription Rights, as applicable, at any time to any Person; provided, however, any Transfer of HoldCo Notes by a HoldCo Noteholders Commitment Party shall be in accordance with
the terms of the Plan Support Agreement.

among other things, the bona fide nature of the investment intent and the accuracy of such Commitment Party’s representations as expressed herein or otherwise made pursuant hereto, and (b) the foregoing shares cannot be sold unless
subsequently registered under the Securities Act or an exemption from registration is available.

 Section 5.7 Purchasing Intent. Such Commitment Party is acquiring the Unsubscribed
Shares for its own account or accounts or funds over which it holds voting discretion, not otherwise as a nominee or agent, and not otherwise with the view to, or for resale in connection with, any distribution thereof not in compliance with
applicable securities Laws, and such Commitment Party has no present intention of selling, granting any other participation in, or otherwise distributing the same, except in compliance with applicable securities Laws.

matters such that it is capable of evaluating the merits and risks of its investment in the Unsubscribed Shares. Such Commitment Party is an “accredited investor” within the meaning of Rule 501(a) of the Securities Act or a
“qualified institutional buyer” within the meaning of Rule 144A of the Securities Act. Such Commitment Party understands and is able to bear any economic risks associated with such investment (including the necessity of holding such
shares for an indefinite period of time). Except for the representations and warranties expressly set forth in this Agreement or any other Transaction Agreement, such Commitment Party has independently evaluated the merits and risks of its decision
to enter into this Agreement and disclaims reliance on any representations or warranties, either express or implied, by or on behalf of any of the Debtors. 

Section 5.9 No Broker’s Fees. Such Commitment Party is not a party to any Contract with any Person (other than
the Transaction Agreements and any Contract giving rise to the Expense Reimbursement hereunder) that would give rise to a valid claim against any of the Debtors for a brokerage commission, finder’s fee or like payment in connection with the
Rights Offerings, the sale of the Unsubscribed Shares or the payment of the Commitment Premium. 
 Section 5.10 Sufficient
Funds. Such Commitment Party has sufficient assets and the financial capacity to perform all of its obligations under this Agreement, including the ability to fully exercise all Subscription Rights that are owned by it (or such managed funds or

Commitment Parties. Except as otherwise provided in this Agreement, nothing in this Agreement shall give the Commitment Parties, directly or indirectly, any right to control or direct the operations of the Debtors. Prior to the Closing Date, the
Debtors shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision of the business of the Debtors. 

Section 6.4 Access to Information; Confidentiality.

business, properties and personnel as may reasonably be requested by any such party; provided, that the foregoing shall not require the Company (i) to permit any inspection, or to disclose any information, that in the reasonable judgment

(b) From and after the date hereof until the date that is one (1) year after the expiration of the
Pre-Closing Period, each Commitment Party shall, and shall cause its Representatives to, (i) keep confidential and not provide or disclose to any Person any documents or information received or otherwise

Affiliate or Representative of such Commitment Party who needs to know such information for purposes of this Agreement or the other Transaction Agreements and who agrees to observe the terms of this Section 6.4(b) (and such Commitment Party
will remain liable for any breach of such terms by any such Affiliate or Representative)), and (ii) not use such documents or information for any purpose other than in connection with this Agreement or the other Transaction Agreements or the
transactions contemplated hereby or thereby. Notwithstanding the foregoing, the immediately preceding sentence shall not apply in respect of documents or information that (A) is now or subsequently becomes generally available to the public

or applicable securities exchange rules; provided, that, such Commitment Party or such Representative shall provide the Company with prompt written notice of such legal compulsion and cooperate with the Company to obtain a protective Order or
similar remedy to cause such information or documents not to be disclosed, including interposing all available objections thereto, at the Company’s sole cost and expense; provided, further, that, in the event that such protective
Order or other similar remedy is not obtained, the disclosing party shall furnish only that portion of such information or documents that is legally required to be disclosed and shall exercise its commercially reasonable efforts (at the
Company’s sole cost and expense) to obtain assurance that confidential treatment will be accorded such disclosed information or documents. The provisions of this Section 6.4(b) shall not apply to any Commitment Party that, as of the date
hereof, is party to a confidentiality or non-disclosure agreement with the Debtors, for so long as such agreement remains in full force and effect.

the Company, as the case may be, and any of their respective Subsidiaries, that appears in any filing made with, or written materials submitted to, any Governmental Entity in connection with the transactions contemplated by this Agreement or the
Plan; provided, however, that the Commitment Parties are not required to provide for review in advance declarations or other evidence submitted in connection with any filing with the Bankruptcy Court. In exercising the foregoing
rights, the Parties shall act as reasonably and as promptly as practicable.

ARTICLE VIII  

INDEMNIFICATION AND CONTRIBUTION 

Section 8.1 Indemnification Obligations. Following the entry of the Approval Order, the Company, the Reorganized Debtors and the
other Debtors (the “Indemnifying Parties” and each, an “Indemnifying Party”) shall, jointly and severally, indemnify and hold harmless each Commitment Party and its Affiliates, equity holders, members,
partners, general partners, managers and its and their respective Representatives and controlling persons (each, an “Indemnified Person”) from and against any and all losses, claims, damages, liabilities and costs and
expenses (other than Taxes of the Commitment Parties except to the extent otherwise provided for in this Agreement) arising out of a claim asserted by a third party (collectively, “Losses”) that any such Indemnified Person
may incur or to which any such Indemnified Person may become subject arising out of or in connection with this Agreement and the obligations hereunder, including the Backstop Commitment, the Rights Offerings, the payment of the Commitment Premium or
the use of the proceeds of the Rights Offerings, or any claim, challenge, litigation, investigation or proceeding relating to any of the foregoing, regardless of whether any Indemnified Person is a party thereto, whether or not such proceedings are
brought by the Company, the Reorganized Debtors, the other Debtors, their respective equity holders, Affiliates, creditors or any other Person, and reimburse each Indemnified Person upon demand for reasonable documented (with such documentation
subject to redaction to preserve attorney client and work product privileges) legal or other third-party expenses incurred in connection with investigating, preparing to defend or defending, or providing evidence in or preparing to serve or serving
as a witness with respect to, any lawsuit, investigation, claim or other proceeding relating to any of the foregoing (including in connection with the enforcement of the indemnification obligations set forth herein), irrespective of whether or not
the transactions contemplated by this Agreement or the Plan are consummated or whether or not this Agreement is terminated; provided, that the foregoing indemnity will not, as to any Indemnified Person, apply to Losses (a) as to a
Defaulting Commitment Party, its Related Parties or any Indemnified Person related thereto, caused by a Commitment Party Default by such Commitment Party, or (b) to the extent they are found by a final,
non-appealable judgment of a court of competent jurisdiction, whether such judgment is in such underlying action, suit or proceeding, or otherwise, to arise from the bad faith, willful misconduct or gross
negligence of such Indemnified Person. 
 Section 8.2 Indemnification Procedure. Promptly after receipt by an Indemnified
Person of notice of the commencement of any claim, challenge, litigation, investigation or proceeding (an “Indemnified Claim”), such Indemnified Person will, if a claim is to be made hereunder against the Indemnifying Party
in respect thereof, notify the Indemnifying Party in writing of the commencement thereof; provided, that (a) the omission to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have
hereunder except to the extent it has been materially prejudiced by such failure and 

  
 52 

 
(b) the omission to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability that it may have to such Indemnified Person otherwise than on account of this
Article VIII. In case any such Indemnified Claims are brought against any Indemnified Person and it notifies the Indemnifying Party of the commencement thereof, the Indemnifying Party will be entitled to participate
therein, and, at its election by providing written notice to such Indemnified Person, the Indemnifying Party will be entitled to assume the defense thereof, with counsel reasonably acceptable to such Indemnified Person; provided, that if the
parties (including any impleaded parties) to any such Indemnified Claims include both such Indemnified Person and the Indemnifying Party and based on advice of such Indemnified Person’s counsel there are legal defenses available to such
Indemnified Person that are different from or additional to those available to the Indemnifying Party, such Indemnified Person shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense
of such Indemnified Claims. Upon receipt of notice from the Indemnifying Party to such Indemnified Person of its election to so assume the defense of such Indemnified Claims with counsel reasonably acceptable to the Indemnified Person, the
Indemnifying Party shall not be liable to such Indemnified Person for expenses incurred by such Indemnified Person in connection with the defense thereof or participation therein (other than reasonable costs of investigation) unless (i) such
Indemnified Person shall have employed separate counsel (in addition to any local counsel) in connection with the assertion of legal defenses in accordance with the proviso to the immediately preceding sentence (it being understood, however, that
the Indemnifying Party shall not be liable for the expenses of more than one separate counsel representing the Indemnified Persons who are parties to such Indemnified Claims (in addition to one local counsel in each jurisdiction in which local
counsel is required)), (ii) the Indemnifying Party shall not have employed counsel reasonably acceptable to such Indemnified Person to represent such Indemnified Person within a reasonable time after the Indemnifying Party has received notice
of commencement of the Indemnified Claims from, or delivered on behalf of, the Indemnified Person, (iii) after the Indemnifying Party assumes the defense of the Indemnified Claims, the Indemnified Person determines in good faith that the
Indemnifying Party has failed or is failing to defend such claim and provides written notice of such determination and the basis for such determination, and such failure is not reasonably cured within ten (10) Business Days of receipt of such
notice, or (iv) the Indemnifying Party shall have authorized in writing the employment of counsel for such Indemnified Person. Notwithstanding anything herein to the contrary, the Debtors shall have sole control over any Tax controversy or Tax
audit and shall be permitted to settle any liability for Taxes of the Debtors. 
 Section 8.3 Settlement of Indemnified Claims.
In connection with any Indemnified Claim for which an Indemnified Person is assuming the defense in accordance with this Article VIII, the Indemnifying Party shall not be liable for any settlement of any Indemnified Claims effected by such
Indemnified Person without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed). If any settlement of any Indemnified Claims is consummated with the written consent of the
Indemnifying Party or if there is a final judgment for the plaintiff in any such Indemnified Claims, the Indemnifying Party agrees to indemnify and hold harmless each Indemnified Person from and against any and all Losses by reason of such
settlement or judgment to the extent such Losses are otherwise subject to indemnification by the Indemnifying Party hereunder in accordance with, and subject to the limitations of, this Article VIII. The Indemnifying Party shall not, without
the prior written consent of an Indemnified Person (which consent shall be 

  
 53 

 
granted or withheld, conditioned or delayed in the Indemnified Person’s sole discretion), effect any settlement of any pending or threatened Indemnified Claims in respect of which indemnity
or contribution has been sought hereunder by such Indemnified Person unless (i) such settlement includes an unconditional release of such Indemnified Person in form and substance satisfactory to such Indemnified Person from all liability on the
claims that are the subject matter of such Indemnified Claims and (ii) such settlement 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 Person. 

Section 8.4 Contribution. If for any reason the foregoing indemnification is unavailable to any Indemnified Person or
insufficient to hold it harmless from Losses that are subject to indemnification pursuant to Section 8.1, then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Person as a result of
such Loss in such proportion as is appropriate to reflect not only the relative benefits received by the Indemnifying Party, on the one hand, and such Indemnified Person, on the other hand, but also the relative fault of the Indemnifying Party, on
the one hand, and such Indemnified Person, on the other hand, as well as any relevant equitable considerations. It is hereby agreed that the relative benefits to the Indemnifying Party, on the one hand, and all Indemnified Persons, on the other
hand, shall be deemed to be in the same proportion as (a) the total value received or proposed to be received by the Company and the Reorganized Debtors pursuant to the issuance and sale of the Rights Offering Shares in the Rights Offerings
contemplated by this Agreement and the Plan bears to (b) the Commitment Premium paid or proposed to be paid to the Commitment Parties. The Indemnifying Parties also agree that no Indemnified Person shall have any liability based on their
comparative or contributory negligence or otherwise to the Indemnifying Parties, any Person asserting claims on behalf of or in right of any of the Indemnifying Parties, or any other Person in connection with an Indemnified Claim. 

Section 8.5 Treatment of Indemnification Payments. All amounts paid by an Indemnifying Party to an Indemnified Person under this
Article VIII shall, to the extent permitted by applicable Law, be treated as adjustments to the Per Share Purchase Price for all Tax purposes. The provisions of this Article VIII are an integral part of the transactions contemplated by
this Agreement and without these provisions the Commitment Parties would not have entered into this Agreement. The Approval Order shall provide that the obligations of the Company and the Reorganized Debtors under this Article VIII shall
constitute allowed administrative expenses of the Debtors’ estate under sections 503(b) and 507 of the Bankruptcy Code and are payable without further Order of the Bankruptcy Court, and that the Company and the Reorganized Debtors may
comply with the requirements of this Article VIII without further Order of the Bankruptcy Court. 
 Section 8.6 No
Survival. All representations, warranties, covenants and agreements made in this Agreement shall not survive the Closing Date except for covenants and agreements that by their terms are to be satisfied after the Closing Date, which covenants and
agreements shall survive until satisfied in accordance with their terms.

Section 3.3 and to pay the Commitment Premium pursuant to and in accordance with Section 3.2 shall survive the termination of this Agreement and shall remain in full force and effect in case, until
such obligations have been satisfied, (ii) the provisions set forth in Article VIII and Article X shall survive the termination of this Agreement in accordance with their terms, in each case so long as the Approval Order has been
entered by the Bankruptcy Court prior to the date of termination, and (iii) subject to Section 10.10, nothing in this Section 9.4 shall relieve any Party from liability for its gross
negligence or any willful or intentional breach of this Agreement. For purposes of this Agreement, “willful or intentional breach” means a breach of this Agreement that is a consequence of an act undertaken by the breaching
Party with the knowledge that the taking of such act would, or would reasonably be expected to, cause a breach of this Agreement.

provisos applicable to Section 3.2(a) entirely in cash to the Commitment Parties or their designees. To the extent that all amounts due in respect of the Commitment Premium pursuant to this Section 9.4(b) have actually been paid by the
Debtors to the Commitment Parties in connection with a termination of this Agreement, the Commitment Parties shall not have any additional recourse against the Debtors for any obligations or liabilities relating to or arising from this Agreement,
except for liability for bad faith, willful misconduct or gross negligence of this Agreement pursuant to Section 8.1 or except as otherwise provided in Section 9.4(a). Except as set forth in this Section 9.4(b), the
Commitment Premium shall not be payable upon the termination of this Agreement. The Commitment Premium shall, pursuant to the Approval Order, constitute allowed administrative expenses of the Debtors’ estate under sections 503(b)
and 507 of the Bankruptcy Code.

Agreement, nor will 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.

 Section 10.15 Relationship Among Parties. 

(a) Notwithstanding anything herein to the contrary, the duties and obligations of the Commitment Parties, on the one hand, and the Debtors,
on the other hand, arising under this Agreement shall be several, not joint. No Party shall have any responsibility by virtue of this Agreement for any trading by any other entity. No prior history, pattern, or practice of sharing confidences among
or between the Parties shall in any way affect or negate this Agreement. The Parties hereto acknowledge that this Agreement does not constitute an agreement, arrangement, or understanding with respect to acting together for the purpose of acquiring,
holding, voting, or disposing of any equity securities of the Debtors and the Commitment Parties do not constitute a “group” within the meaning of Rule 13d-5 under the Securities Exchange Act of
1934, as amended. Nothing contained herein or any Definitive Documentation and no action taken by any Commitment Party pursuant to this Agreement shall be deemed to constitute or to create a presumption by any parties that the Commitment Parties are
in any way acting in concert or as a “group” (or a joint venture, partnership or association), and the Debtors will not assert any such claim with respect to such obligations or the transactions contemplated by this Agreement or the
Definitive Documentation, and the Debtors acknowledge that neither the HoldCo Equityholders Commitment Parties nor the HoldCo Noteholder Commitment Parties are acting in concert or as a group with respect to such obligations or the transactions
contemplated by this Agreement or the Definitive Documentation. The Debtors acknowledge and each HoldCo Equityholder Commitment Party and each HoldCo Noteholder Commitment Party confirms that it has independently participated in the negotiation of
the transactions contemplated under this Agreement and the Definitive Documentation with the advice of counsel and advisors. 
 (b) In
connection with any matter requiring consent or a request of the Requisite Commitment Parties under this Agreement, there is no requirement or obligation that such holders agree among themselves to take such action and no agreement among such
holders with respect to any such action. In connection with any matter that may be requested by the Requisite Commitment Parties, each such holder may, through its counsel, make such request; provided, that the Company will only be required to take
such action if it receives the request of the Requisite Commitment Parties, as the case may be. In connection with any matter requiring consent of the Requisite Commitment Parties hereunder, the Company will solicit consent independently from each
such holder or its respective counsel; provided, that such consent shall only be granted if the approval of the Requisite Commitment Parties (as applicable) is obtained. 

(c) It is understood and agreed that none of the Commitment Parties has any duty of trust or confidence in any form with any other Commitment
Party, the Debtors, or any of the Debtors’ creditors or other stakeholders and, except as expressly provided in this Agreement, there are no agreements, commitments or undertakings by, among or between any of them with respect to the subject
matter hereof. For the avoidance of doubt, the foregoing sentence does not include any fiduciary obligations owed by any Plan Support Party that has been appointed an officer of any Debtor.

 Exhibit A 

Rights Offering Procedures 

 ULTRA PETROLEUM CORP. (THE “COMPANY”) 

RIGHTS OFFERING PROCEDURES1 

Each Rights Offering Share (as defined below) is being distributed and issued by the Company (i) pursuant to an effective registration statement under
the Securities Act of 1933, as amended (the “Securities Act”; such offering, a “Registered Rights Offering”), or (ii) without registration under the Securities Act, in reliance upon the exemption provided in
Section 1145 of the Bankruptcy Code (such offering, an “1145 Rights Offering”). None of the Subscription Rights (as defined below) or the Rights Offering Shares issuable upon exercise of such rights distributed pursuant to
these Rights Offering Procedures in reliance upon the exemption provided in Section 1145 of the Bankruptcy Code have been or will be registered under the Securities Act, nor any state or local law requiring registration for offer and sale of a
security. 
 If the Rights Offering is a Registered Rights Offering, the Subscription Rights will be immediately detachable and freely transferable
separately from HoldCo Notes or HoldCo Equity Interests, as applicable; provided however that the transferability of Subscription Rights held by an Affiliate (as that term is defined under Rule 144 promulgated under the Securities Act (“Rule
144”) of the Company may be subject to limitations on transferability under the Securities Act. 
 If the Rights Offering is an 1145 Rights
Offering, the Subscription Rights will not be detachable or transferable separately from HoldCo Notes or HoldCo Equity Interests, as applicable. Rather, the Subscription Rights together with the underlying HoldCo Notes or HoldCo Equity Interests
with respect to which such Subscription Rights were issued, will trade together as a unit, subject to such limitations, if any, that would be applicable to the transferability of the underlying HoldCo Notes or HoldCo Equity Interests; and, provided
further, that following the exercise of any Subscription Rights, the holder thereof shall be prohibited from transferring or assigning the HoldCo Notes or the HoldCo Equity Interests, as applicable, corresponding to such Subscription Rights until
the earlier of (i) termination of the Rights Offering and (ii) the revocation of exercise of the Subscription Rights to the extent permitted by these Rights Offering Procedures. 

The Disclosure Statement (as defined below) has previously been distributed in connection with the Debtors’ solicitation of votes to accept or reject
the Plan (as 
  

	1 	 Terms used and not defined herein shall have the meaning assigned to them in the Plan Support Agreement, dated
as of November 21, 2016 (including the terms and conditions set forth in the Plan Term Sheet attached as Exhibit A to the Plan Support Agreement (the “Plan Term Sheet”), the terms and conditions set forth in the Backstop
Commitment Agreement attached as Exhibit B to the Plan Support Agreement (the “Backstop Agreement”) and collectively, including all the other exhibits thereto, as may be amended, supplemented or otherwise modified from time to time,
the “Plan Support Agreement”)). 

 
defined below) and that document sets forth important information, including risk factors, that should be carefully read and considered by each Eligible Holder (as defined below) prior to making
a decision to participate in the Rights Offering (as defined below). Additional copies of the Disclosure Statement are available upon request from the Subscription Agent. 

The Rights Offering is being conducted by the Company in good faith and in compliance with the Bankruptcy Code. In accordance with Section 1125(e) of the
Bankruptcy Code, a debtor or any of its agents that participate, in good faith and in compliance with the applicable provisions of the Bankruptcy Code, in the offer, issuance, sale, or purchase of a security offered or sold under the plan of the
debtor, of an affiliate participating in a joint plan with the debtor, or of a newly organized successor to the debtor under the plan, is not liable, on account of such participation, for violation of any applicable law, rule, or regulation
governing the offer, issuance, sale or purchase of securities. 

 Eligible Holders (as defined below) should note the following times relating to the Rights Offering: 

 

					
	 Date
	  	 Calendar Date
	  	 Event

	Record Date	  	[●], 2016	  	The date and time fixed by the Company pursuant to the Plan for the determination of the holders eligible to receive Subscription Rights.
			
	Subscription Commencement Date	  	[●], 2017	  	Commencement of the Rights Offering.
			
	Subscription Expiration Deadline	  	4:00 p.m. Houston time on [●], 2017	  	 The deadline for Eligible Holders to subscribe for Rights Offering Shares. An Eligible Holder’s applicable Beneficial Holder
Subscription Form(s) (with accompanying IRS Form W-9 or appropriate IRS Form W-8, as applicable) must be received by the Eligible Holder’s Nominee (as defined
below) in sufficient time to allow such Nominee to deliver the Master Subscription Form to the Subscription Agent by the Subscription Expiration Deadline.
  

Eligible Holders who are not Commitment Parties must deliver the aggregate Purchase Price (as defined below) by the Subscription Expiration Deadline.

 
 Eligible Holders who are Commitment Parties must deliver the aggregate Purchase Price no
later than the deadline specified in the Funding Notice (as defined below) in accordance with the terms of the Backstop Agreement.

 To Eligible Holders and Nominees of Eligible Holders: 

On [●], 2016, the Debtors filed the Debtors’ Joint Chapter 11 Plan of Reorganization (as may be amended, modified, or
supplemented from time to time in accordance with the terms thereof, the “Plan”) with the United States Bankruptcy Court for the Southern District of Texas, Houston Division, and the Disclosure Statement for the Debtors’
Joint Chapter 11 Plan of Reorganization (as may be amended from time to time in accordance with its terms, the “Disclosure Statement”). Pursuant to the Plan, each Holder of an Allowed HoldCo Notes Claim (each such holder,
together with its permitted transferees, an “Eligible HoldCo Noteholder”) as of the Record Date shall receive HoldCo Noteholders Subscription Rights (as defined below) pursuant to the HoldCo Noteholders Rights Offering (as defined
below), and each Holder of an Allowed HoldCo Equity Interest (each such holder, together with its permitted transferees, an “Eligible HoldCo Equityholder” and, together with the Eligible HoldCo Noteholders, “Eligible
Holders”) as of the Record Date shall receive HoldCo Equityholders Subscription Rights (as defined below) pursuant to the HoldCo Equityholder Rights Offering (as defined below), in each case, in accordance with the terms and conditions of
these Rights Offering Procedures. The HoldCo Noteholders Rights Offering and the HoldCo Equityholders Rights Offering are collectively referred to herein as the “Rights Offering”. Notwithstanding anything to the contrary contained
herein, in the event that the Rights Offering is a Registered Rights Offering, the Subscription Rights shall be immediately detachable and trade separately from the underlying Allowed HoldCo Notes Claims and the Allowed HoldCo Equity Interests, as
applicable, and there shall be no limitation (except for those limitations imposed by applicable securities law, if any) on the person or persons that may exercise any of the rights transferred hereunder. For the avoidance of doubt, in such
circumstance, for purposes of determining who may exercise a Subscription Right, the terms “Eligible Holder,” “Eligible HoldCo Noteholder” and “Eligible HoldCo Equityholder” shall include any person that validly holds
the Subscription Right as of the date of exercise, without any requirement that such person hold a Noteholder Claim or Equityholder Interest as of such date. 

Pursuant to the Plan, each Eligible HoldCo Noteholder as of the Record Date will receive rights to subscribe for its pro rata portion
of 75 percent of the Shares (as defined below) offered in the Rights Offering (the “HoldCo Noteholders Rights Offering,” and such Shares, the “HoldCo Noteholders Rights Offering Shares”), which HoldCo
Noteholder Rights Offering Shares, collectively, will reflect an aggregate purchase price of $435,000,000 calculated by multiplying the number of Shares offered in the HoldCo Noteholder Rights Offering by the Purchase Price.
“Shares” shall be the fully diluted number of shares of Reorganized HoldCo before taking into account issuances of Shares pursuant to the management incentive plan to be adopted by the Company. “Purchase Price”
shall be the quotient of $2.7 billion divided by the Shares based on a Total Enterprise Value of the Debtors of $6.0 billion, subject to the adjustment provided in the definition of Purchase Price and Total Enterprise Value in the Backstop
Agreement. Each Nominee will receive a Master Subscription Form which it shall use to summarize the Subscription Rights exercised by each Eligible HoldCo Noteholder that timely returns the applicable properly filled out Beneficial Holder
Subscription Form(s) to such Nominee. Beneficial Holder Subscription Forms should only be returned directly to the 

 
Subscription Agent if the Eligible HoldCo Noteholder is the direct holder of record on the books of the applicable indenture trustee and does not hold its Allowed HoldCo Notes Claim through a
Nominee. 
 Pursuant to the Plan, each Eligible HoldCo Equityholder as of the Record Date will receive rights to subscribe for its pro
rata portion of 25 percent of the Shares offered in the Rights Offering (the “HoldCo Equityholders Rights Offering,” and such Shares, the “HoldCo Equityholders Rights Offering Shares” and, together with the
HoldCo Noteholders Rights Offering Shares, the “Rights Offering Shares”), which HoldCo Equityholder Rights Offering Shares, collectively, will reflect an aggregate purchase price of $145,000,000 calculated by multiplying the number
of Shares offered in the HoldCo Equityholder Rights Offering by the Purchase Price. Each Nominee will receive a Master Subscription Form which it shall use to summarize the Subscription Rights exercised by each Eligible HoldCo Equityholder that
timely returns the applicable properly filled out Beneficial Holder Subscription Form(s) to such Nominee. Beneficial Holder Subscription Forms should only be returned directly to the Subscription Agent if the Eligible HoldCo Equityholder is the
direct holder of record on the books of the applicable transfer agent and does not hold its HoldCo Equity Interests through a Nominee. 

Please note that all Beneficial Holder Subscription Forms (with accompanying IRS Form W-9 or
appropriate IRS Form W-8, as applicable) must be returned to the applicable Nominee in sufficient time to allow such Nominee to process and deliver the Master Subscription Form and copies of all Beneficial
Holder Subscription Forms, and the accompanying IRS Forms prior to the Subscription Expiration Deadline. To the extent of any discrepancy between the Master Subscription Form and the Beneficial Holder Subscription Form(s) regarding the Eligible
Holder’s principal amount, the Master Subscription Form shall govern. While the amount of time necessary for a Nominee to process and deliver the Master Subscription Form to the Subscription Agent will vary from Nominee to Nominee, Eligible
Holders are urged to consult with their Nominees to determine the necessary deadline to return their Beneficial Holder Subscription Forms. Failure to submit such Beneficial Holder Subscription Forms on a timely basis will result in forfeiture of an
Eligible Holder’s rights to participate in the Rights Offering. None of the Company, the Subscription Agent or any of the Commitment Parties will have any liability for any such failure. 

No Eligible Holder shall be entitled to participate in the Rights Offering unless the aggregate Purchase Price (as defined below) for the
Rights Offering Shares it subscribes for is received by the Subscription Agent (i) in the case of an Eligible Holder that is not a Commitment Party, by the Subscription Expiration Deadline, and (ii) in the case of an Eligible Holder that
is a Commitment Party, no later than the deadline specified in a written notice (a “Funding Notice”) delivered by or on behalf of the Debtors to the Commitment Parties in accordance with Section 2.4 of the Backstop Agreement
(the “Backstop Funding Deadline”), provided that the Commitment Parties may deposit their aggregate Purchase Price in the Escrow Account (as defined below), in accordance with the terms of the Backstop Agreement. No interest is
payable on any advanced funding of the Purchase Price. If the Rights Offering is terminated for any reason, the aggregate Purchase Price previously received by the Subscription Agent will be returned to Eligible Holders as provided in Section 6
hereof. No 

 
interest will be paid on any returned Purchase Price. Any Eligible Holder who is not a Commitment Party submitting payment via its Nominee must coordinate such payment with its Nominee in
sufficient time to allow the Nominee to forward such payment to the Subscription Agent by the Subscription Expiration Deadline. 
 To
participate in the Rights Offering, an Eligible Holder must complete all of the steps outlined below. If an Eligible Holder does not complete all of the steps outlined below by the Subscription Expiration Deadline or the Backstop Funding Deadline,
as applicable, such Eligible Holder shall be deemed to have forever and irrevocably relinquished and waived its right to participate in the Rights Offering. 
  

	 	1.	Rights Offering 

 Eligible HoldCo Noteholders have the right, but not the obligation, to
participate in the HoldCo Noteholders Rights Offering, and Eligible HoldCo Equityholders have the right, but not the obligation, to participate in the HoldCo Equityholders Rights Offering. 

Eligible HoldCo Noteholders as of the Record Date shall receive rights to subscribe for their pro rata portion of the HoldCo
Noteholders Rights Offering Shares, and Eligible HoldCo Equityholders as of the Record Date shall receive rights to subscribe for their pro rata portion of the HoldCo Equityholders Rights Offering Shares. 

Subject to the terms and conditions set forth in the Plan and these Rights Offering Procedures, each Eligible HoldCo Noteholder as of the
Record Date is entitled to receive rights to subscribe for up to [●] HoldCo Noteholders Rights Offering Shares per $1,000 of Principal Amount of 5.75% Senior Notes Due 2018 issued by the Company and up to [●] HoldCo Noteholders Rights
Offering Shares per $1,000 of Principal Amount of 6.125% Senior Notes Due 2024 issued by Company at the Purchase Price. The difference in the number of Rights Offering Shares that an Eligible HoldCo Noteholder is entitled to subscribe for with
respect to each series of HoldCo Notes is to take into account the differing amounts, as of the Record Date, of pre-petition accrued and unpaid interest thereon. 

Subject to the terms and conditions set forth in the Plan and these Rights Offering Procedures, each Eligible HoldCo Equityholder as of the
Record Date is entitled to receive rights to subscribe for up to [●] HoldCo Equityholders Rights Offering Shares per HoldCo Equity Interest at the Purchase Price. 

There will be no over-subscription privilege in the Rights Offering. Any Rights Offering Shares that are unsubscribed by the Eligible Holders
entitled thereto will not be offered to other Eligible Holders but will be purchased by the applicable Commitment Parties in accordance with the Backstop Agreement. Subject to the terms and conditions of the Backstop Agreement, each Commitment Party
is obligated to purchase its pro rata portion of the applicable Rights Offering Shares. 
 To the extent the Rights Offering Shares
are distributed and issued without registration under the Securities Act, in reliance upon the exemption provided in Section 1145 of the Bankruptcy Code, any Eligible Holder that subscribes for Rights Offering Shares and is deemed

 
to be an “underwriter” under Section 1145(b) of the Bankruptcy Code will be subject to restrictions under the Securities Act on its ability to resell those securities. Resale
restrictions are discussed in more detail in Article [●] of the Disclosure Statement, entitled “Certain Securities Law Matters.” 

To the extent the Rights Offering Shares are distributed and issued with registration under the Securities Act, any Eligible Holder that
subscribes for Rights Offering Shares and is deemed to be an “affiliate” under Rule 144 may be subject to restrictions under Rule 144 on its ability to resell those securities. Resale restrictions are discussed in more detail in Article
[●] of the Disclosure Statement, entitled “Certain Securities Law Matters.” 
 SUBJECT
TO THE TERMS AND CONDITIONS OF THE RIGHTS OFFERING PROCEDURES AND THE BACKSTOP AGREEMENT IN THE CASE OF ANY COMMITMENT PARTY, ALL SUBSCRIPTIONS SET FORTH IN THE APPLICABLE BENEFICIAL HOLDER SUBSCRIPTION FORM(S) ARE IRREVOCABLE. 

 

	 	2.	Subscription Period 

 The Rights Offering will commence on the Subscription Commencement
Date and will expire at the Subscription Expiration Deadline. Each Eligible Holder intending to purchase Rights Offering Shares in any Rights Offering must affirmatively elect to exercise its Subscription Rights in the manner set forth in the
applicable Subscription Form by the Subscription Expiration Deadline. 
 Any exercise of the subscription rights to purchase HoldCo
Noteholders Rights Offering Shares (the “HoldCo Noteholders Subscription Rights”) by an Eligible HoldCo Noteholder after the Subscription Expiration Deadline will not be allowed and any purported exercise received by the
Subscription Agent after the Subscription Expiration Deadline, regardless of when the documents or payment relating to such exercise were sent, will not be honored, except that the Company shall have the discretion, with the consent of the Holdco
Noteholder Commitment Parties holding at least sixty-six and two-thirds percent (66-2/3%) of all outstanding HoldCo Noteholders
Backstop Commitments at the time of the relevant determination (the “HoldCo Noteholder Requisite Commitment Parties”), to allow any exercise of HoldCo Noteholders Subscription Rights after the Subscription Expiration Deadline. 

Any exercise of the subscription rights to purchase HoldCo Equityholders Rights Offering Shares (the “HoldCo Equityholders
Subscription Rights” and, together with the HoldCo Noteholders Subscription Rights, the “Subscription Rights”) by an Eligible HoldCo Equityholder after the Subscription Expiration Deadline will not be allowed and any
purported exercise received by the Subscription Agent after the Subscription Expiration Deadline, regardless of when the documents or payment relating to such exercise were sent, will not be honored, except that the Company shall have the
discretion, with the consent of the Holdco Equityholder Commitment Parties holding at least sixty-six and two-thirds percent
(66-2/3%) of all outstanding HoldCo Equityholders Backstop Commitments at the time of the relevant determination (the “HoldCo Equityholder Requisite Commitment Parties” and together with the
HoldCo Noteholder Requisite Commitment Parties, the “Requisite Commitment Parties”), to allow any exercise of HoldCo Equityholders Subscription Rights after the Subscription Expiration Deadline. 

 The Subscription Expiration Deadline may be extended with the consent of the Requisite Commitment
Parties, or as required by law. 
  

	 	3.	Delivery of Subscription Documents 

 Each Eligible Holder may exercise all or any portion
of such Eligible Holder’s Subscription Rights, but subject to the terms and conditions contained herein. In order to facilitate the exercise of the Subscription Rights, beginning on the Subscription Commencement Date, the applicable
Subscription Form and these Rights Offering Procedures will be sent to each Eligible Holder, together with appropriate instructions for the proper completion, due execution and timely delivery of the executed Subscription Form and the payment of the
applicable aggregate Purchase Price for its Rights Offering Shares.

Price, payable for the Rights Offering Shares elected to be purchased by such Eligible Holder, by the Subscription Expiration Deadline. Eligible Holders that are Commitment Parties must deliver their payment of the applicable Purchase Price payable
for the Rights Offering Shares elected to be purchased by such Commitment Party directly to the Subscription Agent or to the Escrow Account, as applicable, no later than the Backstop Funding Deadline. 

 

	 	(d)	In the event that the funds received by the Subscription Agent or the Escrow Account, as applicable, from any Eligible Holder do not correspond to the Purchase Price payable for the Rights Offering Shares elected to be
purchased by such Eligible Holder, the number of the Rights Offering Shares deemed to be purchased by such Eligible Holder will be the lesser of (a) the number of the Rights Offering Shares elected to be purchased by such Eligible Holder and
(b) a number of the Rights Offering Shares determined by dividing the amount of the funds received by the Purchase Price, in each case up to such Eligible Holder’s pro rata portion of Rights Offering Shares. 

 

	 	(e)	The cash paid to the Subscription Agent in accordance with these Rights Offering Procedures will be deposited and held by the Subscription Agent in a segregated account until released to the Debtors in connection with
the settlement of the Rights Offering on the Effective Date. The Subscription Agent may not use such cash for any other purpose prior to the Effective Date and may not encumber or permit such cash to be encumbered with any lien or similar
encumbrance. The cash held by the Subscription Agent hereunder shall not be deemed part of the Debtors’ bankruptcy estates. 

	 	5.	Transfer Restriction; Revocation 

 If the Rights Offering is an 1145 Rights Offering:

  

	 	•	 	The Subscription Rights will not be detachable or transferable separately from HoldCo Notes or HoldCo Equity Interests, as applicable. If any Subscription Rights are transferred by an Eligible Holder in contravention of
the foregoing, the Subscription Rights will be cancelled, and neither such Eligible Holder nor the purported transferee will receive any Rights Offering Shares otherwise purchasable on account of such transferred Subscription Rights;

  

	 	•	 	The Subscription Rights together with the underlying HoldCo Notes or HoldCo Equity Interests with respect to which such Subscription Rights were issued, will trade together as a unit, subject to such limitations, if
any, that would be applicable to the transferability of the underlying HoldCo Notes or HoldCo Equity Interests; and 

  

	 	•	 	Once an Eligible Holder has properly exercised its Subscription Rights, subject to the terms and conditions contained in these Rights Offering Procedures and the Backstop Agreement in the case of any Commitment Party,
such exercise will be irrevocable. Moreover, following the exercise of any Subscription Rights, the holder thereof shall be prohibited from transferring or assigning the HoldCo Notes or the HoldCo Equity Interests, as applicable, corresponding to
such Subscription Rights until the earlier of (i) termination of the Rights Offering and (ii) the revocation of exercise of the Rights to the extent permitted by these Rights Offering Procedures. 

If the Rights Offering is a Registered Rights Offering: 
  

	 	•	 	the Subscription Rights will immediately be detachable from the HoldCo Notes or the HoldCo Equity Interests with respect to which they were distributed, as applicable, and trade separately from any such claims or
interests, and nothing in these Rights Offering Procedures should limit the separate transferability of HoldCo Notes or HoldCo Equity Interests. 

  

	 	6.	Termination/Return of Payment 

 Unless the Effective Date has occurred, the Rights
Offering will be deemed automatically terminated without any action of any party upon the earlier of (i) termination of the Plan Support Agreement in accordance with its terms, (ii) termination of the Backstop Agreement in accordance with
its terms and (iii) the Outside Date (as such date may be extended pursuant to the terms of the Backstop Agreement). In the event the Rights Offering is terminated, any payments received pursuant to these Rights Offering Procedures will be
returned, without interest, to the applicable Eligible Holder as soon as reasonably practicable. 
  

	 	7.	Settlement of the Rights Offering and Distribution of the Rights Offering Shares 

 The
settlement of the Rights Offering is conditioned on confirmation of the Plan by the Bankruptcy Court, compliance by the Debtors with these Rights Offering Procedures, and the 

 
simultaneous occurrence of the Effective Date. The Debtors intend that the Rights Offering Shares will be issued to the Eligible Holders and/or to any party that an Eligible Holder so designates
in the Beneficial Holder Subscription Form(s), in book-entry form, and that The Depository Trust Company (“DTC”), or its nominee, will be the holder of record of such Rights Offering Shares. To the extent DTC is unwilling or unable
to make the Rights Offering Shares eligible on the DTC system, the Rights Offering Shares will be issued directly to the Eligible Holder or its designee. 
  

	 	8.	Fractional Shares 

 No fractional rights or Rights Offering Shares will be issued in the
Rights Offering. All share allocations (including each Eligible Holder’s Rights Offering Shares) will be calculated and rounded down to the nearest whole share. 
  

	 	9.	Validity of Exercise of Subscription Rights 

 All questions concerning the timeliness,
viability, form and eligibility of any exercise of Subscription Rights will be determined in good faith by the Debtors in consultation with the Requisite Commitment Parties, and, if necessary, subject to a final and binding determination by the
Bankruptcy Court. The Debtor, with the consent of the Requisite Commitment Parties, may waive or reject any defect or irregularity in, or permit such defect or irregularity to be corrected within such time as they may determine in good faith, the
purported exercise of any Subscription Rights. Subscription Forms will be deemed not to have been received or accepted until all irregularities have been waived or cured within such time as the Debtors determine in good faith in consultation with
the Requisite Commitment Parties. 
 Before exercising any Subscription Rights, Eligible Holders should read the Disclosure Statement and
the Plan for information relating to the Debtors and the risk factors to be considered. 
 All calculations, including, to the extent
applicable, the calculation of (a)(i) the value of any Eligible HoldCo Noteholder’s Allowed HoldCo Notes Claim for the purposes of the HoldCo Noteholders Rights Offering and (ii) any Eligible HoldCo Noteholder’s HoldCo Noteholders
Rights Offering Shares, shall be made in good faith by the Company with the consent of the HoldCo Noteholders Requisite Commitment Parties and (b)(i) the value of any Eligible HoldCo Equityholders’ HoldCo Equity Interests for the purposes of
the HoldCo Equityholders Rights Offering and (ii) any Eligible HoldCo Equityholders’ HoldCo Equityholders Rights Offering Shares, shall be made in good faith by the Company with the consent of the HoldCo Equityholders Requisite Commitment
Parties and in each case in accordance with any claim amounts included in the Plan, and any disputes regarding such calculations shall be subject to a final and binding determination by the Bankruptcy Court. 

 

	 	10.	Modification of Procedures 

 With the prior written consent of the Requisite Commitment
Parties, the Debtors reserve the right to modify these Rights Offering Procedures, or adopt additional procedures consistent 

 
with these Rights Offering Procedures to effectuate the Rights Offering and to issue the Rights Offering Shares, provided, however, that the Debtors shall provide prompt written notice to each
Eligible Holder of any material modification to these Rights Offering Procedures made after the Subscription Commencement Date, provided further that any amendments or modifications to the terms of the Rights Offering are subject to the provisions
of Section 10.7 of the Backstop Agreement. In so doing, and subject to the consent of the Requisite Commitment Parties, the Debtors may execute and enter into agreements and take further action that the Debtors determine in good faith is
necessary and appropriate to effectuate and implement the Rights Offering and the issuance of the Rights Offering Shares. 
 To the extent
applicable, the Debtors shall undertake reasonable procedures to confirm that each participant in the Rights Offering is in fact an Eligible Holder. 
  

	 	11.	Depository Trust Company (“DTC”) 

 Some or all of the Allowed HoldCo Notes
Claims and the Allowed HoldCo Equity Interests are held in book-entry form in accordance with the practices and procedures of the DTC. The Debtors intend to comply with the practices and procedures of DTC for the purpose of conducting the Rights
Offering, and, subject to compliance with Section 11 hereof, these Rights Offering Procedures will be deemed appropriately modified to achieve such compliance. 

Without limiting the foregoing the Company intends, that to the extent practicable, the Rights Offering Shares will be issued in book entry
form, except with respect to persons that may be deemed underwriters under section 1145(b) of the Bankruptcy Code, and that DTC, or its nominee, will be the holder of record of such Rights Offering Shares. The ownership interest of each holder of
such Rights Offering Shares, and transfers of ownership interests therein, will be recorded on the records of the direct and indirect participants in DTC. Holders who exercise the Subscription Rights may be required to furnish the Company or its
agents information regarding their broker, bank or other securities nominee in order that the Rights Offering Shares for which they have subscribed can be properly credited to their securities account. To the extent required, the Company intends to
solicit such information on a timely basis, so that the Rights Offering Shares may be delivered to the holders exercising their Subscription Rights on or as promptly as practicable after the Effective Date. 

 

	 	12.	Inquiries And Transmittal of Documents; Subscription Agent 

 The Rights Offering
Instructions for Eligible Holders attached hereto should be carefully read and strictly followed by the Eligible Holders. 
 Questions
relating to the Rights Offering should be directed to the Subscription Agent via email to [[[●] (please reference “Subscription Rights Offering” in the subject line) or at the following phone number: [●]].

Purchase Price for the Rights Offering Shares that you elect to purchase.

is aware of their status as a Commitment Party). 

  

	5.	Read, complete and sign the certification in Item 5 of your applicable Beneficial Holder Subscription Form(s). Such execution shall indicate your acceptance and approval of the terms and conditions
set forth in these Rights Offering Procedures.
