(c)                                   If the Proposed Aggregate Net Working Capital Amount is not prepared and delivered by Purchaser within the thirty (30) day period set forth in Section 2.04(b) above, Seller shall be entitled (but not obligated) during the thirty (30) day period commencing on the thirty-first (31 st ) day after the Closing Date to prepare (at Seller’s expense) and deliver to Purchaser a worksheet setting forth Seller’s good faith computation of the Proposed Aggregate Net Working Capital Amount, which computation shall be prepared in the same format and on the same basis used to prepare the Estimated Aggregate Net Working Capital Amount, and based upon information available to Seller, and accompanied by the documentation that supports Seller’s determinations and calculations.  If within ten (10) days following delivery of such worksheet and supporting documentation, Purchaser does not object in writing thereto to Seller,

13

then the Proposed Aggregate Net Working Capital Amount submitted by Seller pursuant to this Section 2.04(c) shall constitute the Final Aggregate Net Working Capital Amount.  If, within ten (10) days following delivery of such worksheet and supporting documentation, Purchaser objects in writing thereto to Seller (describing in reasonable detail the specific line items and values that are in dispute and the reasons for such dispute, and proposing alternative values with respect to such specific line items), such Proposed Aggregate Net Working Capital Amount shall be subject to the objection and resolution provisions set forth in Section 2.04(e) below.

(d)                                  If neither Purchaser nor Seller prepare and timely deliver a Proposed Aggregate Net Working Capital Amount in accordance with Section 2.04(b) or (c) , above, the Estimated Aggregate Net Working Capital Amount delivered at Closing shall become the Final Aggregate Net Working Capital Amount for all purposes hereunder.

(e)                                   If Seller timely objects to Purchaser’s Proposed Aggregate Net Working Capital Amount pursuant to Section 2.04(b) or if Purchaser timely objects to Seller’s Proposed Aggregate Net Working Capital Amount pursuant to Section 2.04(c) , then Purchaser and Seller shall negotiate in good faith and attempt to resolve the particular items and values that are identified in the applicable written notice of objection over a twenty (20) day period commencing on delivery of written notice of objection pursuant to Section 2.04(b) or (c) , as the case may be.  Should such negotiations not result in an agreement as to the Final Aggregate Net Working Capital Amount within such twenty (20) day period (or such longer period as Purchaser and Seller may mutually agree), then either Party may submit such disputed items and values to the Neutral Auditor.  Each Party agrees to promptly execute a reasonable engagement letter, if requested to do so by the Neutral Auditor.  Purchaser and Seller, and their respective Representatives, shall cooperate fully with the Neutral Auditor.  The Neutral Auditor, acting as an expert and not an arbitrator, shall resolve such disputed items and determine the values to be ascribed thereto, and using those values (together with other items not in dispute) determine the Final Aggregate Net Working Capital Amount as of the Closing Date only (prepared on the same basis used to prepare the Estimated Aggregate Net Working Capital Amount).  The Parties hereby agree that the Neutral Auditor shall only decide the specific disputed items, the values ascribed thereto and using those values (together with the other items included in the applicable Proposed Aggregate Net Working Capital Amount) determine the Final Aggregate Net Working Capital Amount, and the Neutral Auditor’s decision with respect to such disputed items and values must be within the range of values assigned to each such item in the applicable Proposed Aggregate Net Working Capital Amount and the notice of objection, respectively.  All fees and expenses relating to the work, if any, to be performed by the Neutral Auditor will be borne equally by Purchaser and Seller.  The Neutral Auditor shall be directed to resolve the disputed items and amounts and deliver to Purchaser and Seller a written determination of the Final Aggregate Net Working Capital Amount (such determination to be made consistent with this Section 2.04(e) , including a worksheet setting forth all material calculations used in arriving at such determination and to be based solely on information provided to the Neutral Auditor by Purchaser and Seller) within thirty (30) days after being retained, which determination will be final, binding and conclusive on the Parties and their respective Affiliates and representatives, successors and assigns.  Notwithstanding anything herein to the contrary, the dispute resolution

14

mechanism contained in this Section 2.04(e) shall be the exclusive mechanism for resolving disputes, if any, regarding the Aggregate Net Working Capital, if any, and neither Seller nor Purchaser shall be entitled to indemnification pursuant to Article 11 for Losses resulting or arising from the amount of the Aggregate Net Working Capital Amount or the determination of Aggregate Net Working Capital.

(f)                                    The “ Final Aggregate Net Working Capital Adjustment Amount ” shall be calculated by computing the Closing Day Aggregate Net Working Capital Adjustment Amount in accordance with Section 2.04(a) but substituting Final Aggregate Net Working Capital Amount for the Estimated Aggregate Net Working Capital Amount.  The “ Post-Closing Aggregate Net Working Capital Adjustment Amount ” shall be the amount equal to (i) the Final Aggregate Net Working Capital Adjustment Amount minus (ii) the Closing Date Aggregate Net Working Capital Adjustment Amount.  If the Post-Closing Aggregate Net Working Capital Adjustment Amount is a positive amount, then Purchaser shall pay in cash to Seller the amount of the Post-Closing Aggregate Net Working Capital Adjustment Amount.  If the Post-Closing Aggregate Net Working Capital Adjustment Amount is a negative amount, then Seller shall pay in cash to Purchaser the amount equal to the absolute value of the Post-Closing Aggregate Net Working Capital Adjustment Amount. Any such net excess or deficit payment in respect of the Final Aggregate Net Working Capital Amount will be due and payable within fifteen (15) days after the Final Aggregate Net Working Capital Amount is finally determined as provided in this Section 2.04 and will be payable by wire transfer of immediately available funds to such account or accounts as shall be specified by Purchaser or Seller, as applicable.  Any payments made pursuant to this Section 2.04(f) shall be treated as an adjustment to the Purchase Price by the parties for Tax purposes, unless otherwise required by applicable Law.

(g)                                   Following the Closing, Seller and Purchaser shall cooperate and provide each other and, if applicable the Neutral Auditor, and their respective representatives, reasonable assistance and access to such books, records and employees (including those of HoldCo and the Subsidiaries) as are reasonably requested in connection with the matters addressed in this Section 2.04 .  Consistent with the foregoing, if Purchaser prepares the worksheet in accordance with Section 2.04(b) , Purchaser shall, at its expense, provide or provide reasonable access (in a manner not unreasonably disruptive to its business) to Seller or the Neutral Auditor to review the books and records, documents and work papers related to the preparation of the worksheet and computation of the Final Aggregate Net Working Capital Amount and if Seller prepares the worksheet in accordance with Section 2.04(c) , then Seller shall, at its expense, provide or provide reasonable access (in a manner not unreasonably disruptive to its business) to Purchaser or the Neutral Auditor to review the books and records, documents and work papers related to the preparation of the worksheet and computation of the Final Aggregate Net Working Capital Amount.  If Purchaser prepares the worksheet in accordance with Section 2.04(b) , Seller and the Neutral Auditor shall be entitled to make reasonable inquiries and information requests of Purchaser regarding the worksheet setting forth the computation of the Final Aggregate Net Working Capital Amount and the calculations set forth therein and if Seller prepares the worksheet in accordance with Section 2.04(c) , Purchaser and the Neutral Auditor shall be entitled to make reasonable inquiries and information requests of Seller regarding the worksheet

(b)                                  Settlement of Losses .  If the Indemnified Party has assumed the defense of any claim by a third party which may give rise to indemnity hereunder pursuant to Section 11.06(d) , the Indemnified Party shall not settle, consent to the entry of a judgment of or compromise such claim without the prior written consent (which consent shall not be unreasonably withheld or delayed) of the Indemnifying Party.

11.06                  Rights of Indemnifying Party in the Defense of Third Party Claims .

(b)                                  Procedure .  If the Indemnifying Party assumes the defense of any such claim, the Indemnifying Party shall (i) select counsel reasonably acceptable to the Indemnified Party to conduct the defense of such claim and (ii) take all steps necessary in the defense or settlement thereof, at its sole cost and expense.  The Indemnified Party shall be entitled to participate in (but not control) the defense of any such claim, with its own counsel and at its sole

41

cost and expense; provided that, if the claim includes allegations for which the Indemnifying Party both would and would not be obligated to indemnify the Indemnified Party, the Indemnifying Party and the Indemnified Party shall in that case jointly assume the defense thereof.  The Indemnified Party and the Indemnifying Party shall fully cooperate with each other and their respective counsel in the defense or settlement of such claim.  The Party in charge of the defense shall keep the other Party appraised at all times as to the status of the defense or any settlement negotiations with respect thereto.

(d)                                  Decline to Assume the Defense .  The Indemnified Party may defend against any such claim, at the sole cost and expense of the Indemnifying Party, in such manner as it may deem reasonably appropriate, including settling such claim in accordance with the terms hereof if (i) the Indemnifying Party does not assume the defense of any such claim resulting therefrom within thirty (30) days after the date the Indemnifying Party is notified of such claim by the Indemnified Party or (ii) the Indemnified Party reasonably concludes that the Indemnifying Party is (a) not diligently defending the Indemnified Person, (b) not contesting such claim in good faith through appropriate proceedings or (c) has not taken such action (including the posting of a bond, deposit or other security) as may be necessary to prevent any action to foreclose a Lien against or attachment of any asset or property of the Indemnified Party for payment of such claim.

11.07                  Direct Claims .   In the event that any Indemnified Party has a claim against any Indemnifying Party which may give rise to indemnity hereunder that does not involve a claim brought by a third party, the Indemnified Party shall promptly notify the Indemnifying Party of the claim and the facts constituting the basis for such claim and, if known, the amount or an estimate of the amount of the liability arising therefrom.  If the Indemnifying Party does not notify the Indemnified Party within thirty (30) days from receipt of such claim notice that the Indemnifying Party disputes such claim, the amount of such claim shall be conclusively deemed a liability of the Indemnifying Party hereunder; however if the Indemnifying Party does notify the Indemnified Party that it disputes such claim within the require thirty (30) day period, the Parties shall attempt in good faith to agree upon the rights of the respective Parties with respect to such claim.  If the Parties should so agree, a memorandum setting forth such agreement shall be prepared and signed by both Parties.  If such Parties shall not agree, the Indemnified Party shall be entitled to take any action in law or in equity as such Indemnified Party shall deem necessary to enforce the provisions of this Article 11 against the Indemnifying Party.

42

Agreement, and the Parties shall not be entitled to a rescission of this Agreement or to any further indemnification rights or claims of any nature whatsoever in respect thereof, all of which the Parties hereto hereby waive.

(b)                                  Upon making any payment to the Indemnified Party for any indemnification claim pursuant to this Article 11 , the Indemnifying Party shall be subrogated, to the extent of such payment, to any rights which the Indemnified Party may have against any third parties with respect to the subject matter underlying such indemnification claim and the Indemnified Party shall assign any such rights to the Indemnifying Party.

11.11                  No Solicitation .   Seller shall not, and shall not authorize or permit HoldCo, any Subsidiary, any of its Affiliates or any of its or their Representatives to, directly or indirectly, (i) encourage, solicit, initiate, facilitate or continue inquiries regarding an Acquisition Proposal; (ii) enter into discussions or negotiations with, or provide any information to, any Person concerning a possible Acquisition Proposal or (iii) enter into any agreements or other instruments (whether or not binding) regarding an Acquisition Proposal.  Seller shall immediately cease and cause to be terminated, and shall cause HoldCo, any Subsidiary, any of its Affiliates and all of its and their Representatives to immediately cease and cause to be terminated, all existing discussions or negotiations with any Persons conducted heretofore with respect to, or that could lead to, an Acquisition Proposal.

SELLER PARENT GUARANTY

NRG ENERGY, INC.

THIS GUARANTY (“ Guaranty ”), effective as of May       , 2014, by NRG Energy, Inc., a Delaware corporation (“ Guarantor ”), is to and for the benefit of NRG Yield Operating LLC, a Delaware limited liability company (“ Buyer ”) and the Purchaser Indemnified Parties (collectively, “ Beneficiary ”).  Capitalized terms not otherwise defined herein shall have the meaning given such terms in the Contract (as such term is defined below).

W I T N E S S E T H:

WHEREAS, NRG Gas Development Company, LLC (“ Obligor ”) and Buyer have of even date herewith entered into that certain Purchase and Sale Agreement (as such agreement may be amended, modified or supplemented from time to time, the “ Contract ”) for the sale by Obligor to Buyer of the Acquired Interests;

WHEREAS, Obligor is a wholly owned indirect subsidiary of Guarantor; and

WHEREAS, Section 5.07 of the Contract requires that this Guaranty be executed and delivered by Guarantor concurrently with the execution of the Contract;

NOW THEREFORE, for valuable consideration and as an inducement to Buyer to enter into the Contract, Guarantor covenants with Obligor as follows:

1.                                       Guarantor hereby unconditionally guarantees to Beneficiary the full and timely performance when due, the payment of all amounts when due and owing, and observance when due of all covenants, terms and agreements to be performed, paid or observed, as applicable, by Obligor under the Contract, all whether presently existing or from time to time hereafter created, incurred or arising (collectively, the “Obligations”).  Notwithstanding any other provisions of this Guaranty to the contrary, this Guaranty shall not modify or expand the Obligations under the Contract (which Obligations shall be limited as expressly set forth in the Contract).  This Guaranty is a continuing guarantee, and shall apply to all Obligations whenever arising.

2.                                       Guarantor covenants to Buyer that if at any time Obligor defaults in the payment or performance when due of any of its Obligations, Guarantor shall, promptly upon written notice by Beneficiary (provided that no notice is required in case of an automatic stay), pay or perform, or cause the payment or performance of, such Obligations.

3.                                       It is expressly understood and agreed by Guarantor that, to the extent Guarantor’s obligations hereunder relate to Obligations which require performance other than the payment of

I-1

money, Beneficiary may proceed against Guarantor to effect specific performance thereof (to the extent such relief is available) or for payment of damages (as limited by the Contract) resulting from Obligor’s nonperformance.  Subject to the provisions of Section 16 hereof, Guarantor hereby covenants to perform or cause to be performed all of the obligations, terms and conditions on the part of Obligor to be performed under the Contract for the balance of the term thereof.  Should the Contract be disaffirmed by the trustee in bankruptcy for Obligor, then (without limiting the provisions of Section 6(h)) at the option of Buyer, and subject to the provisions of Section 16 hereof, Guarantor shall make and enter into a new agreement to perform or cause to be performed the balance of the Obligations, which new agreement shall be in form and substance identical to the Contract.

4.                                       All payments by Guarantor to Beneficiary shall be made in the United States in United States Dollars and shall be paid within thirty (30) days after receipt by Guarantor from Buyer of written demand for such payment (except in those circumstances where giving such demand is prevented by an automatic stay) and shall not be the subject of any offset against any amounts which may be owed by Beneficiary to Guarantor for any reason unrelated to the Contract.  Each and every default or failure by Obligor in making a payment or otherwise discharging or performing any of the Obligations shall give rise to a separate liability of such Obligor to Beneficiary and a separate cause of action hereunder and a separate suit may be brought hereunder as each liability or cause of action arises.

5.                                       Guarantor agrees to pay all costs, expenses and fees, including all reasonable attorneys’ fees, which may be incurred by Beneficiary in enforcing this Guaranty, whether by suit or otherwise, but only to the extent payment or performance under this Guaranty is otherwise due and Beneficiary is the prevailing party in its claim against Guarantor.

6.                                       The obligations of Guarantor under this Guaranty shall be irrevocable, absolute and unconditional, except to the extent that Obligor’s payment or performance would be excused by Beneficiary’s failure to fulfill its obligations under the Contract, and shall remain in full force and effect until such time as set forth in Section 16 hereof.  The obligations of Guarantor shall not be affected, modified or impaired or prejudiced (i) by any other security now or hereafter held by Beneficiary as security for the obligations of the Obligor under the Contract; or (ii) upon the happening from time to time of any one or more of the following whether or not with notice to or consent of Obligor (except to the extent that Obligor’s consent may be required to effectuate a modification of the Contract) or Guarantor:

(a)                                  the taking of any action by Beneficiary to enforce any Obligation or the Contract against Obligor;

(b)                                  the compromise, settlement, release, change, modification, rescission or termination of any of the Obligations;

(c)                                   the waiver by Beneficiary of the payment, performance or observance of any of Obligations;

I-2

(d)                                  the extension of time for payment of any amounts due or of the time for performance of any of the Obligations;

(e)                                   the modification or amendment (whether material or otherwise) of any of the Obligations;

(f)                                    the failure, omission, delay or lack on the part of Beneficiary to enforce, ascertain or exercise any right, power or remedy under or pursuant to the terms of the Contract s or this Guaranty;

(g)                                   the fact that Guarantor may at any time in the future dispose of all or any part of its interest in Obligor, or otherwise alter its investment in Obligor in any manner;

(h)                                  the bankruptcy, insolvency, winding up, dissolution, liquidation, administration, reorganization or other similar or dissimilar failure or financial disability of Obligor, or any legal limitation, disability, incapacity or other circumstances relating to Obligor;

(i)                                      the addition or substitution of any guarantor, maker or other third party primarily or secondarily liable or responsible for the performance or observance of any of the Obligations or by any extension, waiver, amendment or thing whatsoever which may release or discharge (in whole or in part) any such guarantor, maker or other third party (other than as a result of the indefeasible payment and performance of the Obligations in full);

(j)                                     the invalidity, nonbinding effect or unenforceability of (x) the Obligations or (y) the Contract in its entirety; or

(k)                                  the taking, variation, renewal, addition, substitution, subordination, or partial or entire release of any security for the Obligations or the enforcement or neglect to perfect or enforce any such security.

7.                                       Guarantor irrevocably and absolutely waives any and all right of subrogation, contribution, indemnification, reimbursement or similar rights against Obligor with respect to the Guaranty, whether such rights arise under an express or implied contract or by operation of law, it being the intention of Guarantor and Buyer that Guarantor shall not be deemed to be a “creditor” (as defined in Section 101 of the U.S. Bankruptcy Code or any other applicable law) of Obligor by reason of the existence of this Guaranty in the event that Obligor becomes a debtor in any proceeding under the U.S. Bankruptcy Code or any other applicable law.  In addition, Guarantor will not exercise any rights which it may acquire by way of subrogation under this Guaranty by any payment made hereunder or otherwise, until all of the Obligations shall have indefeasibly been paid or performed in full.  If any amount shall be paid to Guarantor on account of such subrogation rights at any time when all the Obligations shall not have been indefeasibly paid or performed in full, such amount shall be held in trust for the benefit of Beneficiary and shall forthwith be paid to Beneficiary and applied to such liabilities and obligations, whether matured or unmatured.

I-3

8.                                       Beneficiary shall have the right, in its sole judgment and discretion, from time to time, to make demand for payment or performance and to proceed against Guarantor for recovery of the total of any and all amounts due, or for the performance of any nonmonetary obligation owed, to Beneficiary pursuant to this Guaranty, or to proceed from time to time against Guarantor for such portion of any and all such amounts, or for the performance of any and all such nonmonetary obligations, as Beneficiary may determine.

9.                                       So long as any Obligations are owed to Beneficiary, Guarantor shall not, without the prior written consent of Buyer, commence or join with any other Person in commencing, any bankruptcy, reorganization or insolvency proceeding against Obligor.  The obligations of Guarantor under this Guaranty shall not be altered, limited or affected by any proceeding, voluntary or involuntary, involving the winding up, dissolution, administration, bankruptcy, reorganization, insolvency, receivership, liquidation or arrangement or similar proceeding of Obligor, or by any defense which Obligor may have by reason of any order, decree or decision of any court or administrative body resulting from any such proceeding.

10.                                With respect to all Obligations, this is a guarantee of payment and performance and not of collection, and Guarantor hereby waives and relinquishes all rights and remedies accorded by applicable law to sureties or guarantors and agrees not to assert or take advantage of any such rights or remedies, including without limitation:

(a)                                  any right to require Beneficiary to proceed against Obligor or any other person or to proceed against or exhaust any security held by Beneficiary at any time or to pursue any other remedy in Beneficiary’s power before proceeding against Guarantor;

(b)                                  any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other person or the failure of Beneficiary to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other person;

(c)                                   any demand, presentment, protest and notice of any kind except as otherwise required under this Guaranty, including without limitation (i) notice of the existence, creation or incurring of any new or additional Obligations, (ii) notice of any breach or default by Obligor under the Contract or of any action or non-action on the part of Beneficiary, Obligor, any creditor of Obligor or Guarantor or on the part of any other person under this or any other instrument in connection with any obligation or evidence of indebtedness held by Beneficiary as collateral or in connection with any Obligations hereby guaranteed;

(d)                                  any defense based upon an election of remedies by Beneficiary which destroys or otherwise impairs the subrogation rights of Guarantor, the right of Guarantor to proceed against Obligor for reimbursement, or both;

(e)                                   any duty on the part of Beneficiary to disclose to Guarantor any facts Beneficiary may now or hereafter know about Obligor, regardless of whether Beneficiary has reason to believe that any such facts materially increase the risk beyond that which Guarantor intends to assume, or has reason to believe that such facts are unknown to Guarantor, or has a

I-4

reasonable opportunity to communicate such facts to Guarantor, since Guarantor acknowledges that Guarantor is fully responsible for being and keeping informed of the financial condition of Obligor and of all circumstances bearing on the risk of non-payment of any Obligations hereby guaranteed; and

(f)                                    any defense arising because of the exercise of any right or remedy available to, or election made by, Beneficiary pursuant to the Federal Bankruptcy Code, whether as an unsecured or undersecured creditor, seeking adequate protection, or otherwise.

Notwithstanding any other provision of this Section 10 to the contrary, Guarantor hereby reserves to itself all rights to which Obligor is or may be entitled arising from or in connection with each of the Contract and the Obligations, except for defenses arising out of the bankruptcy, insolvency, dissolution or liquidation of Obligor or the incapacity or lack of authority of Obligor to enter into or perform its obligations under the Contract, and all rights and remedies accorded by applicable law to sureties or guarantors based on the defense of the statute of limitations related to the enforceability of this Guaranty in any action hereunder or in any action for the payment or performance of any Obligations hereby guaranteed.

11.                                This Guaranty shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns, provided, however, that Guarantor may not make an assignment or other transfer of this Guaranty or any interest herein by operation of law or otherwise unless it has obtained the prior written consent of Buyer (which consent shall be solely within Buyer’s discretion) to such assignment or other transfer.  Buyer may collaterally assign its rights under this Guaranty to any Lender.

12.                                All notices to Guarantor required to be served under this Guaranty shall be in writing and shall be served by registered mail and shall be addressed as follows:
