A full and complete copy of the Merger Agreement (including the Plan of Reorganization, which is attached as an exhibit thereto) has been provided to Oncor Holdings and Oncor.

WHEREAS, the Oncor Entities are “ring-fenced” from the Company and EFIH and their respective Affiliates (as defined below), as a result of which, among other things, (i) the boards of directors of Oncor Holdings and Oncor are comprised of a majority of independent directors and (ii) certain arrangements are in place to maintain the separateness of the business and operations of the Company and EFIH from the business and operations of the Oncor Entities (such limitations collectively, the “Ring-Fence”);

WHEREAS, in furtherance of the Purchase and in light of the Ring-Fence, the Order on Rehearing entered in PUCT Docket No. 34077, the limited liability company agreements (as amended) of Oncor Holdings and Oncor (the “LLC Agreements”), the 2007 Separation Agreement (as defined below) and the Investor Rights Agreement (as defined below), the Company and EFIH have requested that Oncor Holdings and Oncor enter into this letter agreement (“Letter Agreement”) and have provided their prior written consent before execution of this Letter Agreement, as the sole shareholder of Oncor Holdings (in the case of EFIH) and as the direct or indirect 80.03% equity interest holders of Oncor to Oncor Holdings and Oncor with respect to their entry into and performance of this Letter Agreement;

WHEREAS, this Letter Agreement sets forth certain rights and obligations of the Oncor Entities and Purchasers to cooperate in the manner set forth herein with respect to initial steps to be taken in connection with the Mergers (as defined below) (the “Purchase Transaction”);

WHEREAS, this Letter Agreement is not intended to give any Purchaser, directly or indirectly, the right to control or direct the operations of any Oncor Entity prior to the receipt of all approvals required by the Bankruptcy Court, the PUCT (as defined below) and other Governmental Entities (as defined below) and the consummation of the Purchase Transaction (if and when such transactions are consummated);

WHEREAS, Oncor Holdings and Oncor (i) have not endorsed or approved any transactions proposed by the Purchasers, (ii) have not endorsed or approved any of Purchasers’ plans that assume that Texas Transmission Investment LLC will not continue to hold Oncor equity interests nor that same assumption reflected in the Key Regulatory Terms attached as Exhibit B hereto, (iii) are not parties to or bound by the Merger Agreement and (iv) have not approved and are not required to approve the Merger Agreement; provided, however, that Oncor Holdings will engage in the Oncor Holdings Merger on the terms provided in the Merger Agreement, subject to (x) obtaining approval of the Bankruptcy Court as to the Merger Agreement and confirmation of a Plan of Reorganization, and PUCT Approval, (y) receipt of a Merger Agreement that is not inconsistent with this Letter Agreement, and (z) Oncor Holdings Surviving Company being renamed Oncor Electric Delivery Holdings Company LLC and operated and governed in the same manner as Oncor Holdings subject to the PUCT Approval;

Page 2

WHEREAS, except as otherwise approved by the PUCT, following the date hereof, Oncor Holdings shall continue to operate and be governed in substantially the same manner;

WHEREAS, Oncor and Purchasers will cooperate to prepare and support any filings and appearances made before the PUCT, as appropriate, in support of Purchasers’ proposal to acquire Oncor and Oncor Holdings and Purchasers, Oncor and Oncor Holdings agree to use reasonable best efforts to make a single filing by the parties seeking prior approval by the PUCT of the Purchase Transaction;

WHEREAS, Oncor Holdings and Oncor have agreed to operate in the ordinary course of business and materially consistent with the 2017-2018 Plan upon signing of this Letter Agreement, and they have preserved the right to take reasonable actions consistent with prudent industry practices to respond to emergency situations and/or to comply and respond to any requirement, or reasonable request, in a Governmental Request or Order (as defined below); and

WHEREAS, in exchange for the agreements of Oncor Holdings and Oncor in this Letter Agreement, Purchasers have agreed to certain commitments set forth herein with respect to the implications of the Purchase Transaction for Oncor Holdings, Oncor and their employees;

NOW, THEREFORE, in consideration of the premises, representations, warranties, covenants and agreements contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the parties hereto agree as follows:

(d) Notwithstanding any other provision of this Section 8 with respect to any Oncor Employee immediately following the Effective Time whose terms and conditions of employment are covered by a collective bargaining agreement (“CBA”), the terms and conditions of such Oncor Employee’s employment shall be governed by the terms of the applicable CBA, as may be modified from time to time.

(e) Each party hereto hereby acknowledges that, with respect to any employee listed on Exhibit D hereto, a “change in control” or “change of control” within the meaning of each Assumed Plan in which such employee is a participant or to which such employee is a party will occur as a result of the consummation of the Purchase Transaction.

(f) In the event that any Oncor Employee becomes a participant in any employee benefit plan of Purchasers or its Subsidiaries, Purchasers shall use commercially reasonable efforts to cause any employee benefit plans in which such Oncor Employee is entitled to participate to take into account for purposes of eligibility and vesting thereunder, service of such Oncor Employees with Oncor Holdings or Oncor, as applicable, prior to the Effective Time as if such service were with Purchasers

Page 17

(g) The provisions of this Section 8 are solely for the benefit of the parties to this Letter Agreement, and no Oncor Employee or former Oncor Employee or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of this Letter Agreement, and nothing herein shall (i) be construed as an amendment to any Benefit Plan for any purpose, (ii) give any Oncor Employee or former Oncor Employee or any other individual associated therewith or any employee benefit plan or trustee thereof or any other third party any right to enforce the provisions of this Section 8 or (iii) obligate the EFH Surviving Companies, Oncor Holdings Surviving Company or Oncor or any of their respective Affiliates (A) to, subject to Section 8(a)(iii), and as provided in the Split Participant Agreement (as defined below), maintain any particular benefit plan, (B) to retain the employment of any particular employee or (C) to refrain from promoting or demoting any particular employee (or otherwise refrain from reassigning such employee to a new position).

Section 9. Split Participant Agreement. Oncor shall not amend the Split Participant Agreement, dated October 3, 2016, by and between Oncor and Reorganized TCEH (the “Split Participant Agreement”) without the consent of Parent, such consent not to be unreasonably withheld, conditioned or delayed.

Page 18

(c) Nothing contained in this Letter Agreement shall be construed to prohibit the Oncor Entities from obtaining, with the approval of their respective boards of directors, and fully paying the premium for the extension of (i) the directors’ and officers’ liability coverage of the Oncor Entities’ existing directors’, managers’ and officers’ insurance policies, and (ii) Oncor’s existing fiduciary liability insurance policies, in each case for a claims reporting or discovery period of at least six (6) years from and after the Purchase Closing Date with respect to any claim related to any period of time at or prior to the Purchase Closing Date, which policies may be issued by an insurance carrier selected by the Oncor Entities and may contain terms, conditions, retentions and limits of liability that are acceptable to the Oncor Entities in their sole discretion with respect to any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a director or officer of any of the Oncor Entities by reason of him or her serving in such capacity that existed or occurred at or prior to the Purchase Closing Date (including in connection with this Letter Agreement or the transactions or actions contemplated hereby); provided, that, the premiums for the extension of such insurance policies shall not exceed 250% of the annual premiums currently paid by the Oncor Entities for such insurance policies.

(d) If, within six (6) years of the Purchase Closing Date, the EFH Surviving Companies or any of their successors or assigns shall (i) consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, the EFH Surviving Companies or their successors or assigns shall make, to the extent not provided for under applicable Law, proper provisions so that the successors and assigns of the EFH Surviving Companies, as the case may be, assume all of the obligations of the EFH Surviving Companies set forth in this Section 10.

Nothing contained in this Section 12 or otherwise shall require any Oncor Entity to be an issuer or other obligor with respect to the Financing.

(b) During the Interim Period, it is understood that Parent may seek to market and consummate all or a portion of the Financing.

Page 22

any untrue statement of a material fact in information provided by any Oncor Entity or any omission of a material fact required to be stated in such information or necessary in order to make such information not misleading). Parent shall, promptly upon request of Oncor Holdings or Oncor, reimburse any Oncor Entity for all reasonable and documented out-of-pocket costs and expenses incurred by such Oncor Entity (including those of its Representatives) in connection with the cooperation required by this Section 12.

(g) Entire Agreement. This Letter Agreement and the Confidentiality Agreement embody the entire agreement and understanding of the parties in respect of the subject matter contained herein and supersedes all prior agreements and understandings between the parties with respect to such subject matter, and reflect all contractual obligations or commitments with Parent and Merger Subs. The parties hereby further represent that, in entering into this Letter Agreement (i) they have been represented and advised by counsel in connection with this Letter Agreement, which they have entered into voluntarily and of their own choice, and not under coercion or duress; (ii) they are relying upon their own knowledge and the advice of counsel; (iii) they knowingly waive any claim that this Letter Agreement was induced by any misrepresentation or nondisclosure which could have been or was discovered before signing this Letter Agreement; and (iv) they knowingly waive any right to rescind or avoid this Letter Agreement based upon presently existing facts, known or unknown.

(j) No Third Party Beneficiaries. Except as provided in Section 10 (Indemnification; Directors’ and Officers’ Insurance) and Section 12(c) (Financing), Purchasers, Oncor Holdings and Oncor hereby agree that their respective representations, warranties and covenants set forth herein are solely for the benefit of the other parties hereto, in accordance with and subject to the terms of this Letter Agreement, and this Letter Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the covenants set forth herein.

(k) Specific Performance; Limitation of Damages. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Letter Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each of the parties shall be entitled to specific performance and injunctive relief (but not any other form of equitable relief) to prevent or remedy breaches of this Letter Agreement, without the proof of irreparable damage or any actual damages or losses whatsoever. Without limiting the foregoing, the parties hereto agree that a party hereto may not assert that another party to this Letter Agreement is in breach of this Letter Agreement unless such non-breaching party provides the purported breaching party with written notice of such allegation within five (5) Business Days of the non-breaching party or its Affiliates first becoming aware of such purported breach. Prior to the non-breaching party seeking an injunction pursuant to this Section 16(k), the purported breaching party shall have five (5) Business Days after receiving such notice to cure any such breach.

Notwithstanding anything to the contrary in this Letter Agreement, in no event shall any party hereto or their representatives be liable to any other party hereunder for any punitive, incidental, consequential, special or indirect damages, including loss of future revenue or income or opportunity, relating to the breach or alleged breach of this Letter Agreement.

NON-CONSOLIDATION

18. Non-Consolidation Legal Opinion. BHE agrees to obtain a non-consolidation legal opinion that provides that, in the event of a bankruptcy of BHE or any affiliate of BHE, a bankruptcy court would not consolidate the assets and liabilities of Oncor with BHE or any affiliate of BHE.

35. Transition Costs. No BHE employee time and expenses, third party costs, fees, expenses or costs of the transition (“Transition Costs”) will be borne by Oncor’s customers, nor will Oncor seek to include Transition Costs in rates. Transition Costs are those costs necessary to integrate the two companies for Day 1 Readiness, including the one-time transition costs being incurred whether directly or indirectly through affiliate charges to transition Oncor to ownership by BHE and to integrate Oncor’s operations and systems with those of BHE. Provided, however, that Transition Costs do not include Oncor employee time, costs to achieve savings or synergies or costs that reflect reasonable and necessary costs in providing service to the public. “Costs to achieve” reflect amounts incurred to realize operating enhancements, efficiency gains, or costs reduction initiatives.

Oncor will not implement any material involuntary workforce reductions (with respect to either field or corporate personnel) of Oncor employees.

38. Code of Conduct. Oncor will continue to conduct its activities in compliance with its existing code of conduct.

39. Commission Jurisdiction. Oncor and Oncor Holdings will not own, operate, or construct capital assets outside of ERCOT without prior approval from the Commission or take any other action that would impair the Commission’s regulatory jurisdiction. Neither Oncor, Oncor Holdings, BHE nor their respective affiliates will take any action that would subject ERCOT assets to the jurisdiction of the Federal Energy Regulatory Commission (“FERC”); provided, however, that FERC continues to have jurisdiction under sections 210, 211, and 212 of the Federal Power Act (“FPA”) and may direct transmission and interconnection services over certain existing facilities outside of ERCOT; provided further that the existing reliability and critical infrastructure standards administered by the North American Electric Reliability Corporation (“NERC”), through delegation of authority from FERC, may affect the operations of assets that are deemed part of the bulk electric system.

40. Texas Reliability Entity. Oncor will not seek to have another NERC Regional Entity other than the Texas Reliability Entity serve as the lead regional entity responsible for monitoring Oncor’s activities and ensuring compliance with NERC Reliability Standards.

41. Goodwill. Any costs of goodwill of BHE or its affiliates (including the pre-existing goodwill recognized by Oncor) will not be included in rate base, cost of capital, or operating expenses in future Oncor ratemaking proceedings. Write-downs or write-offs of goodwill will not be included in the calculation of net income for dividend payment purposes.

42. Pushdown Accounting. BHE will not elect to apply pushdown accounting for the merger, i.e., the merger will have no impact on Oncor’s assets being acquired; and any incremental goodwill will not be allocated to, or recognized within, Oncor’s balance sheet.

43. Tangible and Quantifiable Benefits. At a minimum, Oncor will provide the following tangible and quantifiable benefits associated with the merger. Oncor will provide monthly bill credits to electric delivery rates for ultimate credits to customers in an amount equal to 90% of any interest rate savings achieved until: final rates are set in the next Oncor base rate case after the Oncor base rate case currently filed. Savings will not be included in credits if already realized in rates. Interest Rate Savings refers to the improvement in Oncor’s borrowing costs post-close relative to those costs as of June 30, 2017 due to improvement in credit ratings and/or improvement in market spreads. Until final rates are set in the next Oncor base rate case after the Oncor base rate case that is currently filed, Oncor will file a report with the Commission every six months detailing any interest rate savings determined by the amount of debt issued by Oncor by at least 0.15% (amounts above 0.15% being based on actual interest rate savings by Oncor) and demonstrating a calculation of the credit. BHE and Oncor agree to work in good faith with interested parties to determine an acceptable method for implementation of any bill credit to effectuate this commitment, as approved by the Commission. At a minimum, Oncor shall provide retail electric providers 45-day notice of the amount of any customer credits (e.g., for each customer class, the amount per kwh or per-customer credit that would apply) prior to the effective date of the credits and shall implement updated bill credits simultaneously with other changes in Oncor’s rates. In addition, one year after closing, Oncor will present a merger synergy savings analysis to the Commission and provide monthly bill credits to electric rates for inclusion in customer bills in an amount equal to 90% of any synergy savings until final rates are set in the next Oncor base rate proceeding, in which any total synergy savings shall be reflected in Oncor’s rates.

44. LLC Agreements. The Oncor Holdings and Oncor LLC Agreements shall be amended to the extent necessary to effect all of the commitments herein.

The undersigned parties agree to support approval of a transaction by Berkshire Hathaway Energy Company to acquire 100% of Oncor Electric Delivery Company LLC (the “Transaction”), subject to review of the Application presented to the Public Utility Commission of Texas and confirmation that the Transaction (a) includes the foregoing Proposed Regulatory Commitments (the “Commitments”) and (b) the transaction otherwise meets the applicable Public Utility Commission of Texas requirements necessary to find that the Transaction is in the public interest.
