 2.2 Settlement of Claims Against TCEH First Lien Creditors. 

(a) Subject to the occurrence of the Settlement Effective Date, except as otherwise agreed in writing by the Debtors, the Required TCEH
Creditor Parties, and the TCEH Official Committee (including pursuant to the Plan Support Agreement), upon consummation of an Alternative Restructuring of any or all of the TCEH Debtors (other than any TCEH Debtor whose total assets are less than
2.5% of the consolidated total assets, or whose total revenues are less than 2.5% of the consolidated revenues, of the TCEH Debtors as of the date of such Alternative Restructuring), holders of Allowed TCEH First Lien Deficiency Claims, Allowed TCEH
Unsecured Note Claims, Allowed TCEH Second Lien Note Claims, Allowed PCRB Claims, and Allowed General Unsecured Claims Against the TCEH Debtors Other Than EFCH shall receive, in the aggregate, $550 million in Cash (which shall be subject to
reduction only (A) pursuant to (i) Section 11 of the Plan Support Agreement, (ii) Section 2.7 of this Settlement Agreement, and (iii) Section 5 of that certain Settlement & Support Agreement, dated as of
November 23, 2015, by and among EFH, EFIH, EFIH Finance, EECI, Inc., EEC Holdings, Inc., LSGT Gas Company LLC, LSGT SACROC, Inc., TCEH, the EFH/EFIH Committee, the EFH Notes Trustee, the Settling TCEH First Lien Creditors signatory thereto, the
Plan Sponsors, and the TCEH Official Committee, and (B) subject to Bankruptcy Court approval of that certain Stipulation and Settlement Agreement, dated as of December 1, 2015, by and among EFH, TCEH, EFCH, the United States on behalf of
the U.S. Environmental Protection Agency, the Settling TCEH First Lien Creditors signatory thereto, the Plan Sponsors, and the TCEH Official Committee, by $1 million and shall not otherwise be subject to dilution or reduction as a consequence of any
claim or liability incurred as a result of any act, event or transaction) (the “TCEH Cash Payment”). The TCEH Cash Payment shall be made (i) from the Cash on hand at the TCEH Debtors and, if none (or if Cash on hand is
insufficient to make the full amount of the TCEH Cash Payment), the first proceeds of any sale, transfer, or other disposition of the 

  
 13 








 
Prepetition Collateral (as defined in the Final Cash Collateral Order) (including the first proceeds of any financing or similar transaction secured or supported by the Prepetition Collateral)
(the “TCEH Cash Payment Carve Out”) and (ii) before any payment or other distribution (including transfer) is made in connection with such an Alternative Restructuring to the holders of Allowed TCEH First Lien Claims;
provided, however, that the TCEH Cash Payment Carve Out shall be subordinate in all respects to: (a) the RCT Reclamation Support Carve Out (as defined in the Final Cash Collateral Order); (b) the Carve Out (as defined in the
Final Cash Collateral Order); and (c) the Permitted Liens (as defined in the Final Cash Collateral Order). For the avoidance of doubt, any distribution of the TCEH Cash Payment that would otherwise be made to or received by holders of Allowed
TCEH First Lien Deficiency Claims pursuant to this Section 2.2(a), if applicable, shall be subject to Section 2.2(b) of this Settlement Agreement. 

(b) Subject to the occurrence of the Settlement Effective Date, except as otherwise agreed in writing by the Debtors, the Required TCEH
Creditor Parties, and the TCEH Official Committee, in connection with the Plan or upon consummation of an Alternative Restructuring, the Settling TCEH First Lien Creditors will waive, and the TCEH First Lien Agent will not take any action to
interfere or that is inconsistent with the waiver of, any recovery or distribution on account of (but not voting rights in respect of) such Allowed TCEH First Lien Deficiency Claims (including on account of any recovery or distribution provided for
in Section 2.2(a) of this Settlement Agreement) (the “Limited Waiver”) for the benefit of the holders of Allowed TCEH Unsecured Note Claims, Allowed TCEH Second Lien Note Claims, and Allowed General Unsecured Claims Against the
TCEH Debtors Other Than EFCH (collectively, the “Beneficiary-Claimants”), such that any payment or other distribution (including transfer) that would otherwise have been made to, or for the benefit of, one or more of the TCEH First
Lien Creditors on account of their Allowed TCEH First Lien Deficiency Claims pursuant to the Plan or an Alternative Restructuring will instead be paid or distributed pro rata to the Beneficiary-Claimants on the basis of the amounts of their
respective Allowed Claims; provided, however, that, (x) if the Bankruptcy Court (or other court of competent jurisdiction) determines that the Limited Waiver cannot be for the benefit of only the Beneficiary-Claimants, or
(y) the Required TCEH Unsecured Noteholders, the Required TCEH Second Lien Noteholders, and the TCEH Official Committee each agree, in consultation with the Required TCEH First Lien Creditors, that the Limited Waiver should benefit any
non-Beneficiary-Claimants (in whole or in part), then the Limited Waiver shall be for the benefit of the Beneficiary-Claimants and such other holders of Allowed Unsecured Claims against the TCEH Debtors as ordered by such court or agreed to by the
Required TCEH Unsecured Noteholders, the Required TCEH Second Lien Noteholders, and the TCEH Official Committee, in consultation with the Required TCEH First Lien Creditors, but in no event shall include the holders of Allowed TCEH First Lien
Deficiency Claims, such that any payment or other distribution (including transfer) that would otherwise have been made to, or for the benefit of, one or more of the TCEH First Lien Creditors on account of their Allowed TCEH First Lien Deficiency
Claims pursuant to the Plan or an Alternative Restructuring will instead be paid or distributed pro rata to the Beneficiary-Claimants and such other holders of Allowed Unsecured Claims against the TCEH Debtors on the basis of the amounts of their
respective Allowed Claims. For the avoidance of doubt, (A) under no circumstances will any holder of a TCEH First Lien Deficiency Claim receive on account of such claim any portion of or distribution from the TCEH Cash Payment, and (B) the
Limited Waiver shall not increase the aggregate amount of payments, distributions or transfers required pursuant to Section 2.2(a) of this Settlement Agreement and only relates to the allocation of such payments, distributions and transfers as
between the holders of Allowed Unsecured Claims against the TCEH Debtors.

the terms of such releases. 
 (b) Each Party hereby waives, to the fullest extent permitted by applicable law, any right it may have to a

agent, or attorney of any other Party has represented, expressly or otherwise, that such other Party would not, in the event of litigation, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other Parties have been
induced to enter into this Settlement Agreement by, among other things, the mutual waivers and certifications in this Section 3.9. 

  
 34

 3.13 Entire Agreement.

 This Settlement Agreement, including any exhibits, annexes and/or schedules hereto and the exhibits, annexes, and/or schedules thereto,
constitutes the entire agreement between the Parties concerning the subject matter of this Settlement Agreement and supersedes all prior negotiations, agreements and understandings, whether written or oral, between and among the Parties concerning
the subject matter of this Settlement Agreement. Each of the Parties hereto acknowledges that it is executing this Settlement Agreement without reliance on any representations, warranties or commitments other than those representations, warranties
and commitments expressly set forth in this Settlement Agreement. 

  
 38 









	3.14	Modification or Amendment. 

 This Settlement Agreement may be modified or amended only by
written agreement executed by (i) the Required TCEH Creditor Parties, (ii) all of the undersigned Settling Interest Holders, (iii) the Debtors and (iv) the TCEH Official Committee; provided, however, that if the
proposed modification, amendment, or supplement has a material, disproportionate, and adverse effect on any Settling Creditor (in its capacity as a TCEH First Lien Creditor, holder of TCEH Unsecured Note Claims, or holder of TCEH Second Lien Note
Claims), then the consent of each such disproportionately affected Settling Creditor shall also be required to effectuate such modification, amendment, or supplement. 

3.15 Further Assurances.  
 From
and after the Settlement Effective Date, each of the Parties agrees to use their respective commercially reasonable efforts to execute or cause to be executed and deliver or cause to be delivered all such agreements, instruments and documents and
take or cause to be taken all such further actions as may reasonably be necessary from time to time to carry out the intent and purpose of this Settlement Agreement, and to consummate the transactions contemplated hereby and thereby. 

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

 3.17 Interpretation. 
 This
Settlement Agreement is the product of negotiations among the Parties, and the enforcement or interpretation of this Settlement Agreement is to be interpreted in a neutral manner and in accordance with section 102 of the Bankruptcy Code; and any
presumption with regard to interpretation for or against any Party by reason of that Party (or its counsel) having drafted or caused to be drafted this Settlement Agreement or any portion of this Settlement Agreement, shall not be effective in
regard to the interpretation of this Settlement Agreement. 
 3.18 Settlement Discussions. 

This Settlement Agreement and the transactions contemplated herein are part of a proposed settlement among the Parties. Nothing herein shall be
deemed an admission of any kind. To the extent provided by Federal Rule of Evidence 408, all applicable mediation privileges, and any applicable state rules of evidence, this Settlement Agreement and all negotiations relating thereto shall not be
admissible into evidence in any proceeding other than a proceeding to enforce the terms of this Settlement Agreement. 
 3.19 Specific Performance.

 It is understood and agreed by the Parties that money damages would be an insufficient remedy for any breach of this Settlement Agreement
by any Party, that such breach would represent irreparable harm, and that each non-breaching Party shall be entitled to specific performance and injunctive relief (without the posting of any bond and without proof of actual damages), but no other
form of equitable relief, as the sole remedy for any such breach, including an order of the Bankruptcy Court or other court of competent jurisdiction requiring any Party to comply promptly with any of its obligations hereunder; provided, that
each Party agrees to waive any requirement for the securing or posting of a bond in connection with such remedy. 

  
 39 








 3.20 Headings. 

Titles and headings in this Settlement Agreement are inserted for convenience of reference only and are not intended to affect the
interpretation or construction of the Settlement Agreement. 
 3.21 Execution of Agreement. 

This Settlement Agreement may be executed in counterparts, and by the different Parties hereto on separate counterparts, each of which when
executed and delivered shall constitute an original. Delivery of an executed counterpart by facsimile or electronic mail shall be equally as effective as delivery of an original executed counterpart. 

3.22 Non-Severability of Agreement.  

This Settlement Agreement is to be construed as a whole, and all provisions of it are to be read and construed together. Notwithstanding
anything in this Settlement Agreement or the Settlement Order to the contrary, and in light of the integrated nature of the settlements and compromises embodied in this Settlement Agreement and the Settlement Order, in the event that (a) a
court of competent jurisdiction enters a final order ruling that any of the provisions of this Settlement Agreement or the Settlement Order are void, invalid, illegal, or unenforceable in any material respect, or (b) any of the provisions of
this Settlement Agreement or the Settlement Order are reversed, vacated, overturned, voided, or unwound in any material respect, then in each case, the entirety of this Settlement Agreement (other than this Section 3.22) shall be void ab initio
and of no force and effect and, during any subsequent proceeding, the Parties shall not assert claim preclusion, issue preclusion, estoppel or any similar defense in respect of rights and claims of the Parties that were the subject of this
Settlement Agreement prior to this Settlement Agreement being of no force or effect; provided, however, that, the Settlement Agreement being rendered void ab initio and of no force and effect in accordance herewith shall not impair the
force and effect of the Plan Support Agreement or any order authorizing the Debtors entry into the Plan Support Agreement.
