Liability, as the case may be, shall be effected in accordance with the terms of this Agreement and the applicable Assignment and Assumption Agreement.

asset or liability to be retained by such member of the Company Group pursuant to Section 2.2(b), to expend any money whatsoever unless the necessary funds are advanced (or otherwise made available) by SpinCo or the member of the SpinCo
Group entitled to the Acquired TCEH Asset or Assumed Liability. 
 Section 2.3 Responsibility for Assumed Liabilities Retained by
the Company. If the Company or SpinCo is unable to obtain, or to cause to be obtained, any consent, approval, amendment or release required to transfer an Assumed Liability to a member or members of the SpinCo Group, then the applicable member
of the Company Group shall continue to retain such Assumed Liability and, the applicable member of the SpinCo Group shall, as agent or subcontractor for such member of the Company Group, as the case may be, pay, perform and discharge fully all the
obligations or other Liabilities of such member of the Company Group that constitute or are caused by such Assumed Liabilities, as the case may be, thereunder from and after the Contribution Effective Time. From and after the Contribution Effective
Time, OpCo shall indemnify each Company Indemnified Party, and hold each of them harmless, against any Liabilities arising from any such retained Assumed Liability; provided that OpCo shall have no obligation to indemnify any Company
Indemnified Party that has engaged in any fraud, willful misconduct or knowing and intentional violation of Law, in each case in connection therewith. The Company shall cause each member of the Company Group without further consideration, to pay and
remit, or cause to be paid or remitted, to the applicable member of the SpinCo Group, promptly all money, rights and other consideration received by it or any member of the Company Group in respect of such performance under any agreement, lease,
license or other obligations or Liabilities under any Assumed Liability retained by any member of the Company Group; provided that the Company shall be entitled to offset any amounts owed by the SpinCo Group to any member of the Company Group
hereunder. If and when any such consent, substitution, approval, amendment or release shall be obtained, or the obligations under any agreement, lease, license or other obligations or Liabilities under any Assumed Liability retained by any member of
the Company Group shall otherwise become assignable or able to be novated, the applicable member of the Company Group shall promptly assign, or cause to be assigned, all its obligations and other Liabilities thereunder or any obligations of any
member of the Company Group to the applicable member of the SpinCo Group without payment of further consideration, and the applicable member of the SpinCo Group shall, without the payment of any further consideration, assume such obligations or

Agreement after the TCEH Effective Date, the Parties agree to use their commercially reasonable efforts to retain all Information in their respective possession or control in accordance with the policies or ordinary course practices of the Company
in effect on the TCEH Effective Date or such other policies or practices as may be reasonably adopted by the appropriate Party after the TCEH Effective Date that are substantially consistent with the policies of the Company and its subsidiaries as
in effect on the TCEH Effective Date; provided, that, in any event, the Parties agree to retain such Information in their respective possession or control until the seventh (7th) anniversary of the TCEH Effective Date in accordance with
Section 3.1. 
 (b) Until the seventh (7th) anniversary of the TCEH Effective Date, no Party will destroy,
or permit any of its Subsidiaries to destroy, any Information that would, in accordance with such policies or ordinary course practices described in Section 3.4(a), be archived or otherwise filed in a centralized filing system by such
Party or its applicable Subsidiaries, until the later of the seventh (7th) anniversary of the TCEH Effective Date and the period required by applicable Law. 

  
 10 

 (c) In the event of any Party’s or any of its Subsidiaries’ inadvertent
failure to comply with this Section 3.4, such Party shall be liable to the other Party solely for the amount of any monetary fines or penalties imposed or levied against such other Party by a Governmental Entity (which fines or penalties
shall not include any Liabilities asserted in connection with the claims underlying the applicable Action, other than fines or penalties resulting from any claim of spoliation) as a result of such other Party’s inability to produce Information
caused by such inadvertent failure and, notwithstanding Section 5.2 and Section 5.3, shall not be liable to such other Party for any other Liabilities arising out of its or any of its Subsidiaries’ inadvertent failure to
comply with this Section 3.4; provided, however, no member of the Company Group shall have any Liability to any member of the SpinCo Group under this Section 3.4(c) in connection with any Acquired TCEH Assets or
Assumed Liabilities that are retained by a member of the Company Group pursuant to Section 2.2 or Section 2.3. 

(d) Notwithstanding the foregoing, record retention relating to Taxes shall be governed by Section 7.02 of the Tax
Matters Agreement. 
 Section 3.5 Confidentiality. Each Party recognizes and acknowledges that it has received, or is in
possession of, certain non-public, confidential, or proprietary Information (including trade secrets) of the other Party or its respective Group (the “Confidential Information”). Each Party agrees that it will not, that it will
cause its Affiliates not to, and that it will use commercially reasonable efforts to cause each of its and their respective Representatives not to, for a period of five (5) years after the TCEH Effective Date, directly or indirectly, use
Confidential Information of the other Party or its respective Group for its competitive, commercial or proprietary advantage, or disclose, divulge or publish, whether in written or unwritten form or through any medium, such Confidential Information
publicly or to any Person or group of Persons for any reason or purpose whatsoever, except: (i) to authorized Representatives of such Party as reasonably necessary in the course of performing such Party’s obligations, or enforcing such
Party’s rights, under this Agreement or the other Transaction Agreements and (ii) to the extent required to be disclosed by order of a Governmental Entity, or by subpoena, summons or legal process, or by Law, provided that, to the extent
permitted by Law, the disclosing Party shall provide prompt notice of such disclosure to the applicable other Party, so that such Party whose Confidential Information is required to be disclosed may seek to obtain an order or other reliable
assurance that confidential treatment will be accorded to designated portions of such Confidential Information, and the disclosing Party shall reasonably cooperate with the other Party in connection with such other Party’s efforts to obtain
confidential treatment or similar reliable assurances that the relevant Confidential Information will remain confidential. For purposes of this Section 3.5, such Confidential Information shall not include any Confidential Information that
(a) was or becomes generally available to the public other than as a result of a disclosure by such Person (or its Affiliates or Representatives) in violation of this Agreement, (b) becomes available to such Person or any of such
Person’s Affiliates or Representatives after the date hereof from a source other than the other Party hereto or its respective Group or such Group’s Representatives, provided that such source is not known by such Person to be subject to an
obligation of confidentiality (whether by agreement or otherwise) to the other Party with respect to the Information or (c) was independently developed by such Person (or its Affiliates) after the date hereof without reference to, incorporation
of, or other use of any Confidential Information. The limitations in this Section 3.5 are in addition to, and not in lieu of, any other restrictions by which a Party may be bound (whether by contract or otherwise). 

Section 3.6 Other Agreements Providing for Exchange of Information. 

(a) Any Party that receives, pursuant to a request for Information in accordance with this Article III,
Information that is not relevant to its request shall promptly either destroy such Information or return it to the providing Party, at the option of the providing Party, and if the receiving Party elects to destroy such Information, then the
receiving party shall promptly deliver written confirmation (including by email) of the destruction of such Information to the providing Party. 

  
 11 

 (b) When any Information provided by one Group to the other is no longer needed
for the purposes contemplated by this Agreement or any other Transaction Agreement or is no longer required to be retained by applicable Law, the receiving Party will promptly, after request of the providing Party, at the receiving Party’s
option (and expense), either return to the providing Party all Information in a tangible form (including all copies thereof and all notes, extracts or summaries based thereon) or destroy such Information (and such copies thereof and such notes,
extracts or summaries based thereon); provided that if the receiving Party elects to destroy such Information, then the receiving Party shall promptly deliver written confirmation (including by email) of the destruction of such Information to
the providing Party; and provided, further, that the receiving Party shall not be deemed to have retained or failed to return or destroy any Confidential Information stored in digital format that is deleted from local hard drives so long as
no attempt is made to recover such Confidential Information from servers or back-up sources, provided that any such retained Confidential Information shall remain subject to the terms hereof in all respects. 

(c) Nothing in this Section 3.6 shall require any Receiving Party to destroy or return any Information that the
Receiving Party would routinely retain pursuant to its record retention policies aimed at legal, corporate governance or regulatory compliance or that the Receiving Party is required to retain under any applicable Law or regulation or the terms of
the Tax Matters Agreement or any other Transaction Agreement; provided that any such retained Confidential Information shall remain subject to the terms hereof in all respects for so long as such Confidential Information is so retained. 

Section 3.7 Production of Witnesses; Records; Cooperation. 

(a) After the TCEH Effective Date, except in the case of an adversarial Action by one Party against another Party, each Party
shall use its commercially reasonable efforts to make available to each other Party, upon written request, the former, current and future directors, officers, employees, other personnel and agents of the members of its respective Group as witnesses
and any books, records or other documents within its control or which it otherwise has the ability to make available, to the extent that any such person (giving consideration to business demands of such directors, officers, employees, other
personnel and agents) or books, records or other documents may reasonably be required in connection with any Action in which the requesting Party may from time to time be involved, regardless of whether such Action is a matter with respect to which
indemnification may be sought hereunder; provided, that no such access shall unreasonably interfere with the ongoing operations of such Party and its Subsidiaries; provided, further, that no Party shall be required to make
available to the requesting Party any such persons or materials if doing so could be commercially detrimental, violate any Law or agreement, or waive any attorney-client privilege held by such Party provided, further, that, as
applicable, the Party making such assertion shall, to the extent permitted by applicable Law, provide notice to the receiving party that any Information is being withheld pursuant to this proviso and the Parties shall use their respective
commercially reasonable efforts to find a mutually agreeable solution to any such commercial, legal and/or privilege concerns, including, if applicable, by providing any privileged Information pursuant to a joint defense agreement to be mutually
agreed and executed between the applicable Parties. The requesting Party shall bear all reasonable out-of-pocket costs and expenses in connection therewith. 

(b) For the avoidance of doubt, the provisions of this Section 3.7 are in furtherance of the provisions of
Section 3.1 and shall not be deemed to in any way limit or otherwise modify the Parties’ rights and obligations under Section 3.1.

 13 

 ARTICLE V 

RELEASES AND INDEMNIFICATION 

Section 5.1 Termination of Guarantees. The Parties acknowledge and agree that the obligations of the Company Group under or with
respect to the EFH/TCEH Guarantees shall be terminated and extinguished as of the Contribution Effective Time pursuant to the Plan of Reorganization. 

Section 5.2 General Indemnification by OpCo. Subject to the provisions and limitations of this Article V, from and
after the Contribution Effective Time, OpCo shall indemnify, defend and hold harmless each Person that after the Contribution Effective Time is a member of the Company Group (including all Affiliates of the Company) and each of their respective
Representatives and, as applicable, each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “Company Indemnified Parties”), from and against: 

(a) any Assumed Liability, including the failure of any member of the SpinCo Group or any other Person to pay, perform or
otherwise promptly discharge any Assumed Liability in accordance with its terms, whether prior to, at or after the Contribution Effective Time; 

(b) any TCEH Company Liability, including the failure of any member of the SpinCo Group or any other Person to pay, perform or
otherwise promptly discharge any TCEH Company Liability in accordance with its terms, whether prior to, at or after the Contribution Effective Time; and 

(c) any Liability arising from any breach by any member of the SpinCo Group of any covenant or other agreement (other than any
representation or warranty) set forth in this Agreement or in any Assignment and Assumption Agreement, subject to any limitations of liability provisions and other provisions applicable to any such breach set forth herein or therein. 

Section 5.3 General Indemnification by the Company. Subject to the provisions and limitations of this Article V, from
and after the Contribution Effective Time, the Company shall indemnify, defend and hold harmless each Person that after the Contribution Effective Time is a member of the SpinCo Group (including all Affiliates of SpinCo) and each of their respective
Representatives and, as applicable, each of the heirs, executors, successors and assigns of any of the foregoing, from and against: 

(a) any Excluded Liability, including the failure of any member of the Company Group or any other Person to pay, perform or
otherwise promptly discharge any Excluded Liability in accordance with their respective terms, whether prior to, at or after the Contribution Effective Time; and 

(b) any Liability arising from any breach by any member of the Company Group of any covenant or other agreement (other than
any representation or warranty) set forth in this Agreement or in any Assignment and Assumption Agreement, subject to any limitations of liability provisions and other provisions applicable to any such breach set forth herein or therein. 

Section 5.4 Tax Indemnification. Notwithstanding anything in Article V to the contrary, indemnification for Taxes and
for other matters subject to the Tax Matters Agreement is governed solely by the terms, provisions and procedures of the Tax Matters Agreement and not by this Article V. 

  
 14 

 Section 5.5 Contribution. If the indemnification provided for in this
Article V shall, for any reason, be unavailable or insufficient to hold harmless any Indemnified Party hereunder in respect of any Liability, then each Indemnifying Party shall, in lieu of indemnifying such Indemnified Party, contribute
to the amount paid or payable by such Indemnified Party as a result of such Liability, in such proportion as shall be sufficient to place the Indemnified Party in the same position as if such Indemnified Party were indemnified hereunder, the Parties
intending that their respective contributions hereunder be as close as possible to the indemnification under Section 5.2 and Section 5.3, as the case may be. If the contribution provided for in the previous sentence shall,
for any reason, be unavailable or insufficient to put any Indemnified Party in the same position as if it were indemnified under Section 5.2 or Section 5.3, as the case may be, then the Indemnifying Party shall contribute to
the amount paid or payable by such Indemnified Party as a result of such Liability, in such proportion as shall be appropriate to reflect the relative benefits received by and the relative fault of the indemnifying Party on the one hand and the
Indemnified Party on the other hand with respect to the matter giving rise to the Liability. 
 Section 5.6 Indemnification
Obligations Net of Insurance Proceeds and Other Amounts. Any Liability subject to indemnification or contribution pursuant to this Article V will be (a) net of Insurance Proceeds that are actually received by the Indemnified
Party, (b) decreased by any actual recoveries from third parties pursuant to indemnification or otherwise with respect thereto, (c) decreased by any Tax Benefit actually recovered, and (d) increased by any Tax Cost actually incurred
as a result of the receipt of (or entitlement to) such indemnity payment, as applicable. Accordingly, the amount which any Party (an “Indemnifying Party”) is required to pay to any Person entitled to indemnification under this
Article V (an “Indemnified Party”) will be reduced by any such Insurance Proceeds and/or recoveries actually received from third parties and/or Tax Benefits actually recovered, and increased by Tax Costs actually
incurred, in each case, by or on behalf of the Indemnified Party in respect of the related Liability, as applicable. If an Indemnified Party receives a payment (an “Indemnity Payment”) required by this Agreement from an Indemnifying
Party in respect of any Liability and subsequently receives Insurance Proceeds or any other recovery from a third party (including any Tax Benefit actually recovered), then the Indemnified Party will pay to the Indemnifying Party an amount equal to
the lesser of (x) the amount of such Insurance Proceeds or the amount actually received from the third party (including any Tax Benefit actually recovered) and (y) the Indemnity Payment previously received. If an Indemnified Party receives
an Indemnity Payment from an Indemnifying Party in respect of any Liability and subsequently incurs Tax Costs associated by that Indemnity Payment, then the Indemnifying Party will pay to the Indemnified Party an amount equal to those Tax Costs
promptly after receipt of a reasonably detailed statement of those Tax Costs given by the Indemnified Party to the Indemnifying Party within a reasonable period of time (not to exceed six months) after the Tax Cost is actually incurred. In the case
of Tax Benefits, “actually recovered” means an Indemnified Party actually realizes a Refund or a decrease in Taxes reported on a filed Tax Return (in or with respect to a taxable year that ends on or before December 31, 2021) in
connection with the incurrence or the payment by the Indemnified Party of such fees or costs or indemnifiable amounts determined using a “with and without” methodology (treating any deductions attributable to such fees or costs or
indemnifiable amounts as the last items claimed for any taxable year, including after the utilization of any available net operating loss carryovers). In the case of Tax Costs, “actually incurred” means an Indemnified Party actually
realizes a Tax Cost reported on a filed Tax Return (in or with respect to a taxable year that ends on or before December 31, 2021) in connection with the receipt of (or entitlement to) an Indemnity Payment determined using a “with and
without” methodology (treating any receipt of (or entitlement to) such Indemnity Payment as the last items claimed for any taxable year, including after the utilization of any available net operating loss carryovers). For the avoidance of
doubt, for purposes of determining the amount “actually recovered” (for purposes of Tax Benefits) or “actually incurred” (for purposes of Tax Costs), a netting approach shall be taken for determining any increase or decrease, as
the case may be, of taxable income or loss, net operating losses, deductions or other Tax attributes.

 Section 5.7 Procedures for Indemnification of Third Party Claims. 

(a) If an Indemnified Party receives written notice that a Person (including any Governmental Entity) that is not a member of
the Company Group or the SpinCo Group, or any Affiliate thereof, has asserted any claim or commenced any Action (any such claim or Action, a “Third Party Claim”) that may give rise to an Indemnifying Party’s obligation to
indemnify pursuant to Section 5.2 or Section 5.3, as the case may be, then the Indemnified Party shall provide the Indemnifying Party written notice thereof as promptly as practicable (and no later than fifteen
(15) Business Days, or sooner, if the nature of the Third Party Claim so requires) after becoming aware of the Third Party Claim. Such notice shall describe the Third Party Claim in reasonable detail and include copies of all notices and
documents (including court papers) received by the Indemnified Party relating to the Third Party Claim. Notwithstanding the foregoing, the failure of an Indemnified Party to provide notice in accordance with this Section 5.7(a) shall not
relieve an Indemnifying Party of its indemnification obligations under this Agreement, except to the extent the Indemnifying Party is actually prejudiced by the Indemnified Party’s failure to provide notice in accordance with this
Section 5.7(a). 
 (b) Subject to this Section 5.7(b) and Section 5.7(c), an
Indemnifying Party may elect to control the defense of (and seek to settle or compromise), at its own expense and with its own counsel, any Third Party Claim if the Indemnifying Party irrevocably and unconditionally acknowledges its obligation to
indemnify the Indemnified Party in respect of such Third Party Claim in accordance with and subject to the terms hereof. Within thirty (30) Business Days after the receipt of notice from an Indemnified Party in accordance with
Section 5.7(a), the Indemnifying Party shall notify the Indemnified Party whether the Indemnifying Party will assume responsibility for defending the Third Party Claim. After receiving notice of an Indemnifying Party’s election to
assume the defense of a Third Party Claim, an Indemnified Party shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, but the Indemnified Party shall be responsible
for the fees and expenses of its counsel and, in any event, shall cooperate with the Indemnifying Party in such defense in accordance with Section 5.7(f). If an Indemnifying Party has elected to assume the defense of a Third Party Claim,
then such Indemnifying Party shall be solely liable for all fees and expenses incurred by it in connection with the defense of such Third Party Claim and shall not be entitled to seek any indemnification or reimbursement from the Indemnified Party
for any such fees or expenses incurred during the course of its defense of such Third Party Claim. 
 (c) Notwithstanding
Section 5.7(b), if, in the reasonable opinion of counsel to the Indemnified Party, such Indemnified Party and the Indemnifying Party have actual or potential differing defenses or conflicts of interest between them that make joint
representation inappropriate, then the Indemnified Party shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, and the Indemnifying Party shall bear the reasonable
fees and expenses of one (and only one) such counsel for all Indemnified Parties. 
 (d) If an Indemnifying Party elects not
to assume responsibility for defending a Third Party Claim, or fails to notify an Indemnified Party of its election within thirty (30) Business Days after the receipt of notice from an Indemnified Party as provided in
Section 5.7(b), then the Indemnified Party may defend the Third Party Claim at the cost and expense of the Indemnifying Party; provided, that the Indemnified Party shall not be permitted to settle or compromise any Third Party
Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. If the Indemnified Party is conducting the defense against any such Third Party Claim, then the Indemnified
Party and its counsel shall keep the Indemnifying Party informed of all developments relating to such Third Party Claim and provide copies of all relevant correspondence and documents relating thereto. 

(e) Notwithstanding any other provision of this Agreement, without the prior written consent of any Indemnified Party, no
Indemnifying Party shall consent to the entry of any 

  
 16 

 
judgment or enter into any settlement or compromise of any pending or threatened Third Party Claim for which the Indemnified Party is seeking or may seek indemnity pursuant to this
Section 5.7 unless such judgment or settlement is solely for monetary damages (which shall be fully paid by the Indemnifying Party), does not impose any expense or obligation on the Indemnified Party (other than obligations for which the
Indemnified Party is indemnified hereunder and which are fully paid by the Indemnifying Party), does not involve any finding or determination of wrongdoing or violation of Law by the Indemnified Party and provides for a full, unconditional and
irrevocable release of that Indemnified Party and its Affiliates and Representatives from all liability in connection with the Third Party Claim. 

(f) Each of the Indemnifying Party and the Indemnified Party shall use commercially reasonable efforts to make available to
the other, upon written request, the former, current and future directors, officers, employees, other personnel and agents of the members of its respective Group as witnesses and any books, records or other documents within its control or which it
otherwise has the reasonable ability to make available, to the extent that any such persons (giving consideration to business demands of such directors, officers, employees, other personnel and agents) or books, records or other documents may
reasonably be required in connection with the defense, settlement or compromise, or the prosecution, evaluation or pursuit of any Third Party Claim, and shall otherwise reasonably cooperate in such defense, settlement or compromise, or such
prosecution, evaluation or pursuit, as the case may be of such Third Party Claim; provided, that no such cooperation shall unreasonably interfere with the ongoing operations of such Party and its Subsidiaries; provided, further,
that no Party shall be required to make available to the requesting Party any such Persons or materials if doing so would reasonably be expected to be materially commercially detrimental, violate any Law or agreement, or waive any attorney-client
privilege held by such Party; provided, further, that, as applicable, the Party asserting such detriment, violation or privilege shall, to the extent permitted by applicable Law, provide notice to the receiving party that any
Information is being withheld pursuant to the foregoing proviso and the Parties shall use their respective commercially reasonable efforts to find a mutually agreeable solution to any such commercial, legal and/or privilege concerns, including, if
applicable, by providing any privileged Information pursuant to a joint defense agreement to be mutually agreed and executed between the applicable Parties. The Indemnifying Party shall bear all reasonable out-of-pocket costs and expenses in
connection therewith. 
 Section 5.8 Additional Matters. 

(a) Indemnification or contribution payments in respect of any Liabilities for which an Indemnified Party is entitled to
indemnification or contribution under this Article V shall be paid by the Indemnifying Party to the Indemnified Party as such Liabilities are incurred upon demand by the Indemnified Party, including reasonably satisfactory documentation
setting forth the basis for the amount of such indemnification or contribution payment, including documentation with respect to calculations made and consideration of any Insurance Proceeds and/or recoveries from third parties that actually reduce
the amount of such Liabilities and/or Tax Benefits actually recovered or Tax Costs actually incurred; provided, that no Indemnifying Party shall be entitled to condition, delay or withhold any payment pending claim for, or receipt of, any
Insurance Proceeds and/or recoveries from third parties or actual recovery of any Tax Benefits or actual incurrence of Tax Costs. The indemnity and contribution agreements contained in this Article V shall remain operative and in full
force and effect, regardless of (i) any investigation made by or on behalf of any Indemnified Party and (ii) the knowledge by the Indemnified Party of Liabilities for which it might be entitled to indemnification or contribution hereunder.

 (b) Any claim for indemnification under this Agreement which does not result from a Third Party Claim shall be asserted
by written notice given by the Indemnified Party to the applicable Indemnifying Party. Such Indemnifying Party shall have a period of thirty (30) days 

  
 17 

 
after the receipt of such notice within which to respond thereto. If such Indemnifying Party does not respond within such thirty (30)-day period, such
Indemnifying Party shall be deemed to have refused to accept responsibility to make payment. If such Indemnifying Party does not respond within such thirty (30)-day period or rejects such claim in whole or in part, such Indemnified Party, shall be
free to pursue such remedies as may be available to such party as contemplated by this Agreement without prejudice to its continuing rights to pursue indemnification or contribution hereunder. 

(c) If payment is made by or on behalf of any Indemnifying Party to any Indemnified Party in connection with any Third Party
Claim, such Indemnifying Party shall be subrogated to and shall stand in the place of such Indemnified Party as to any events or circumstances in respect of which such Indemnified Party may have any right, defense or claim relating to such Third
Party Claim against any claimant or plaintiff asserting such Third Party Claim or against any other Person. Such Indemnified Party shall cooperate with such Indemnifying Party in a reasonable manner, and at the cost and expense of such Indemnifying
Party, in prosecuting any subrogated right, defense or claim. 
 Section 5.9 Exclusive Remedy; Limitations of Liability;
Mitigation. After the Contribution Effective Time, except for the rights under Section 7.13, the indemnification and contribution provisions of this Article V shall be the sole and exclusive remedy for the matters set
forth herein and in any Assignment and Assumption Agreement and the transactions contemplated hereby and thereby and no party shall pursue or seek to pursue any other remedy. Neither SpinCo or its Affiliates, on the one hand, nor the Company or its
Affiliates, on the other hand, shall be liable to the other for any Liabilities arising under or relating to this Agreement, any Assignment and Assumption Agreement or the transactions contemplated hereby or thereby that are (i) not direct,
actual damages or (ii) special, indirect, consequential, punitive, exemplary, remote, speculative or similar damages or lost profits (except to the extent such lost profits constitute direct, actual damages) of the other arising in connection
with the transactions contemplated hereby (other than such damages described in this clause (ii) payable to a third party in respect of a Third Party Claim). Any Indemnified Party that becomes aware of a Liability for which it seeks
indemnification or contribution under this Article V shall to the extent required by law mitigate such Liability, and the Indemnifying Party shall not be liable for any such Liability to the extent that it is attributable to the failure
of the Indemnified Party to use such commercially reasonable efforts to mitigate to the extent required by law. For the avoidance of doubt, no provision of this Agreement provides indemnification for a breach, misrepresentation or violation under
the Merger Agreement. 
 Section 5.10 Survival of Indemnities. The rights and obligations of each of the Company and SpinCo and
their respective Indemnified Parties under this Article V shall survive the sale or other transfer by any Party of any Assets or businesses or the assignment by it of any Liabilities. Each Party hereby agrees that prior to the
consummation of any sale or transfer of all or substantially all of the Assets of such Party, it will require the acquirer of such Assets to assume the obligations of such Party under this Agreement as a condition thereto. 

Section 5.11 No Assumption of Discharged Liabilities; Obligations under Transaction Agreements. For the avoidance of doubt, nothing
herein shall require or be construed to effectuate the assumption, for any period of time, of any Liability or Tax discharged, released or otherwise satisfied (or to be discharged, released or otherwise satisfied on the EFH Effective Date) pursuant
to the Plan of Reorganization. Additionally, for the avoidance of doubt, nothing herein shall require or be construed to effectuate the assumption, for any period of time or at all, of any obligations of any Person, or otherwise affect in any way
the rights or obligations of any of the Parties or their respective Groups, under the Plan of Reorganization, the Tax Matters Agreement, the Interim Transition Services Agreement or the Transition Services Agreement (whichever is in effect at the
applicable time), the Split Participant Agreement, the Merger Agreement or any other Transaction Agreement.

 ARTICLE VI 

[RESERVED] 
 ARTICLE VII

 MISCELLANEOUS AND GENERAL; COVENANTS 

Section 7.1 Survival. The representations and warranties of the Parties set forth in this Agreement (other than
Section 4.4) shall not survive the Distribution Effective Time, and shall cease to have any force or effect immediately upon the Distribution Effective Time. The covenants and other agreements contained in this Agreement, and liability
for the breach of any obligations thereunder, shall survive the Distribution Effective Time and shall remain in full force and effect in accordance with their terms. 

Section 7.2 Termination, Wind-Down and Distribution of EFH Non-Qualified Benefit Plans and EFH Split Dollar Life Insurance
Plan. In connection with the termination, wind-down and distribution of the remaining liabilities and obligations of the EFH Non-Qualified Benefit Plans and the EFH Split Dollar Life Insurance Plan as contemplated by the Plan of
Reorganization, the Parties acknowledge and agree that (a) the Company shall (or cause the applicable third party service provider to) provide SpinCo with, and accept all reasonable comments of SpinCo to (i) drafts of all notices and other
written correspondence with participants in such EFH Non-Qualified Benefit Plans and the EFH Split Dollar Life Insurance Plan as soon as reasonably practicable, but, in each case, no later than five (5) Business Days prior to the date of such
distribution to such participants and (ii) any estimated calculations of payouts and distributions to such participants promptly upon receipt of such calculations from the third party administrator of such EFH Non-Qualified Benefit Plans or the
EFH Split Dollar Life Insurance Plan, as applicable, but in each case, no later than fifteen (15) Business Days prior to the making of any such payments or distributions with respect thereto and (b) SpinCo shall review, comment upon and
approve as soon after receipt as is administratively practicable (i) all such notices and other written correspondence with participants in such EFH Non-Qualified Benefit Plans and the EFH Split Dollar Life Insurance Plan and (ii) any such
estimated calculations of payouts and distributions to such participants, in each case from such third parties as are assisting with such terminations, wind-downs and distributions. 

Section 7.3 Regulatory Matters. In connection with obtaining any required approval by the Public Utility Commission of Texas
(the “PUCT”) with respect to the transactions contemplated by the Merger Agreement or any other transaction constituting a direct or indirect change of control of Oncor Electric Delivery Company LLC that requires the approval of the
PUCT (in each case, the “PUCT Filing”), the Company shall use its reasonable best efforts to cause, including by exercising its rights to consent and vote (if any) under the Oncor Agreements as an indirect equity owner of Oncor,
Oncor Electric Delivery Company LLC to request from the PUCT, as part of the PUCT Filing, an order stating that none of TCEH, SpinCo, or any subsidiaries or Affiliates of SpinCo will, from and after the TCEH Effective Date, be subject to any
obligation set forth in the Final Order on Rehearing issued in PUCT Docket No. 34077 on April 24, 2008. The Company’s obligations under this Section 7.3 including using its reasonable best efforts, shall not include any
obligation to (A) pay any amounts to the Oncor Entities (as defined in the Merger Agreement) or any other Person or incur any liabilities or other obligation, (B) execute or enter into or perform any new agreement (other than an agreement
contemplated hereby or in the Plan of Reorganization or that confirms or makes effective its obligations hereunder), or (C) breach any Law or commence any Action against any Person, including any of the Oncor Entities or their respective
officers and managers. 
 Section 7.4 D&O Insurance. 

(a) During the period beginning on the date hereof and ending on the EFH Effective Date, the Company agrees to and to cause
its Subsidiaries to maintain, as in effect immediately prior to the TCEH Effective Date (i) the Company’s and its Subsidiaries’ directors’, managers’ 

  
 19 

 
and officers’ insurance policies, and (ii) the Company’s fiduciary liability insurance policies ((i) and (ii), collectively, the “EFH D&O Policies”), in each
case, with terms, conditions, retentions and limits of liability that are no less advantageous than the coverage provided under the Company’s and its Subsidiaries’ policies as of immediately prior to the TCEH Effective Date with respect to
any actual or alleged error, misstatement, misleading statement, act, omission, neglect, breach of duty or any matter claimed against a current or former director, officer or other Representative of TCEH, the TCEH Companies, the Company Group or the
SpinCo Group or any of their respective Subsidiaries (collectively, the “Pre-Spin Group”) by reason of him or her serving in such capacity (“Wrongful Acts”) that existed or occurred on or prior to the TCEH Effective
Date (including in connection with this Agreement and the transactions or actions contemplated by this Agreement). 
 (b)
The Company agrees that, on or before the EFH Effective Date or any other event constituting a change in control as described in Section IX(C)(2) of the EFH D&O Policies (a “Company Change in Control”), it will obtain and fully
pay the premium for a run-off of the EFH D&O Policies for the benefit of each member of the Pre-Spin Group and their respective current and former directors, officers and other Representatives, in each case for a claims reporting or discovery
period of at least six (6) years from and after the EFH Effective Date (or the effective date of such other Company Change in Control, as applicable) with respect to any claim arising from actual or alleged Wrongful Acts on or prior to the EFH
Effective Date (it being understood that, with respect to any claim arising from actual or alleged Wrongful Acts of such Persons in their capacity as a current or former director or officer or other Representative of any TCEH Company or the SpinCo
Group, such period shall be limited to the period on or prior to the TCEH Effective Date), from insurance carriers with the same or better credit rating as the insurance carrier(s) for the EFH D&O Policies with terms, conditions, retentions and
limits of liability that are no less advantageous than the coverage provided for members of the Pre-Spin Group and their respective current and former directors, officers and other Representatives under the EFH D&O Policies with respect to any
actual or alleged Wrongful Act that existed or occurred on or prior to the EFH Effective Date (the “Run-Off Coverage”). 

(c) If the Company, after its good faith efforts, is unable to obtain such Run-Off Coverage as of the EFH Effective Date, then
the Company shall use its reasonable best efforts to purchase insurance comparable to the EFH D&O Policies for such six-year period with terms, conditions, retentions and limits of liability that are at least as favorable as provided in the EFH
D&O Policies; provided, however, that in no event shall the Company be required to expend for such policies pursuant to this sentence an annual premium amount in excess of 200% of the annual premiums paid by the Company for such
insurance as of immediately prior to the TCEH Effective Date; and provided, further, that if the annual premiums of such insurance coverage exceed such amount, the Company shall obtain a policy with the greatest coverage available for
a cost not exceeding such amount. 
 (d) If the Effective Time under the Merger Agreement occurs and the Company complies
with its obligation under Section 6.8(b) of the Merger Agreement (as such obligations are set forth in the Merger Agreement as of the date hereof and without giving effect to any subsequent amendment thereof) and obtains the “D&O
Insurance” (as defined in the Merger Agreement), then the Company shall be deemed to have satisfied its obligations under Section 7.4(b) and (c) hereof; provided, however that this
Section 7.4(d) shall have no effect and be null and void if the Merger Agreement is terminated or the Effective Time under the Merger Agreement otherwise never occurs. 

(e) Additionally, the Company agrees not to seek or, subject to Section 7.4(c), agree to any changes or amendments
to the EFH D&O Policies or the Run-Off Coverage that have or would reasonably be expected to have the effect of reducing or limiting coverage available to any member of the Pre-Spin Group or any of their respective current and former directors,
officers and other Representatives.

  
 20 

 (f) Within ten (10) Business Days of the written request of SpinCo, the
Company shall provide SpinCo copies of all EFH D&O Policies or Run-Off Coverage policies. 
 (g) The Parties agree that
the provisions of this Section 7.4 are for the benefit of each member of the Pre-Spin Group and their respective current and former directors, officers and other Representatives (collectively, the
“Beneficiaries”). The provisions of this Section 7.4 shall be enforceable by each of the Beneficiaries as if such Person were a party to this Agreement. 

Section 7.5 Amendment. No provision of this Agreement shall be terminated, amended, modified or supplemented by any Party, unless such
termination, amendment, supplement or modification is in writing and signed by each of the Parties. 
 Section 7.6 Waiver of
Default. 
 (a) Any term or provision of this Agreement may be waived, or the time for its performance may be extended,
by the Party or the Parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently given for the purposes of this Agreement if, as to any Party, it is in writing signed by an authorized representative of such Party. 

(b) Waiver by any Party of any default by the other Party of any provision of this Agreement or any Assignment and Assumption
Agreement shall not be construed to be a waiver by the waiving party of any subsequent or other default, nor shall it in any way affect the validity of this Agreement or any Party or prejudice the rights of the other Party or Parties thereafter to
enforce each and every such provision. No failure or delay by any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. 
 Section 7.7 Third Party Beneficiaries. Except (i) for
the indemnification rights under this Agreement of any Indemnified Party in their respective capacities as such, (ii) the Beneficiaries pursuant to Section 7.4 and (iii) as specifically provided in any Assignment and Assumption
Agreement, the provisions of this Agreement and each Assignment and Assumption Agreement are solely for the benefit of the parties hereto and thereto and their respective successors and permitted assigns and are not intended to confer upon any
Person, except the parties hereto and thereto and their respective successors and permitted assigns, any rights or remedies hereunder and there are no third party beneficiaries of this Agreement or any Assignment and Assumption Agreement; and
neither this Agreement nor any Assignment and Assumption Agreement shall provide any third party with any remedy, claim, liability, reimbursement, claim of action or other right in excess of those existing without reference to this Agreement or any
Assignment and Assumption Agreement. 
 Section 7.8 Counterparts. This Agreement may be executed in any number of counterparts
(including by electronic means), each such counterpart being deemed to be an original instrument, and all such counterparts taken together constituting one and the same agreement.

including as finally executed agreements) constitutes the entire agreement of the Parties with respect to the subject matter hereof, and cancels, merges and supersedes all other prior or contemporaneous oral or written agreements, understandings,
representations and warranties both written and oral, among the Parties, with respect to the subject matter hereof. EACH PARTY HERETO AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, NONE OF THE SPINCO GROUP OR
THE COMPANY GROUP MAKES ANY REPRESENTATIONS OR WARRANTIES, AND EACH HEREBY DISCLAIMS ANY OTHER REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, INCLUDING AS TO THE ACCURACY OR COMPLETENESS OF ANY OTHER INFORMATION WITH RESPECT TO, OR IN CONNECTION
WITH, THE NEGOTIATION, EXECUTION OR DELIVERY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, NOTWITHSTANDING THE DELIVERY OR DISCLOSURE OF ANY DOCUMENTATION OR OTHER INFORMATION WITH RESPECT TO ANY ONE OR MORE OF THE FOREGOING. The
Parties further represent that, in entering into this Agreement (a) they have been represented and advised by counsel in connection with this Agreement, which they have entered into voluntarily and of their own choice, and not under coercion or
duress; (b) they are relying upon their own knowledge and the advice of counsel; (c) they knowingly waive any claim that this Agreement was induced by any misrepresentation or nondisclosure which could have been or was discovered before
signing this Agreement; and (d) they knowingly waive any right to rescind or avoid this Agreement based upon presently existing facts, known or unknown. 

Section 7.13 Specific Performance. In the event of any actual or threatened default in, or breach of, any of the terms, conditions and
provisions of this Agreement, the Party or Parties who are or are to be thereby aggrieved shall have the right to specific performance and injunctive or other equitable relief (on an interim or permanent basis) of its rights under this Agreement, in
addition to any and all other rights and remedies at law or in equity, and all such rights and remedies shall be cumulative. The Parties agree that the remedies at law for any breach or threatened breach, including monetary damages, may be
inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at law would be adequate is hereby waived. Any requirements for the securing or posting of any bond with such remedy are also hereby
waived by each of the Parties. 
 Section 7.14 Severability. The provisions of this Agreement shall be deemed severable and the
invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or
unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of

Assets or assume any of the Assumed Liabilities to one or more of its Subsidiaries (including OpCo) without the prior written consent of the Company. For purposes of this Section 7.16, the term “merger” refers to any merger in

(whether in a single transaction or a series of related or unrelated transactions) the Party engaging in such transfer or other disposition shall require the transferee to assume all of such Party’s obligations hereunder. 

Section 7.17 Controlling Documents. To the extent that the provisions of the Plan of Reorganization, the Merger Agreement, the Tax
Matters Agreement, the Amended and Restated Split Participant Agreement or the Interim Transition Services Agreement or the Transition Services Agreement (whichever is in effect at the applicable time) conflict with the provisions of this Agreement,
the provisions of such other agreement or agreements shall govern. 
 Section 7.18 EFH Properties Company Cash. Prior to the
Contribution Effective Time, the Company shall cause the distribution or transfer of all cash held by EFH Properties Company to a member of the Company Group. 

Section 7.19 Split Policies; Covered Letters of Credit. 

(a) Annex A attached hereto sets forth certain workers compensation insurance policies (the “Split
Policies”) that insure workers compensation Liabilities arising out of or resulting from (1) the Company and its Subsidiaries (together, the “Company Policy Liabilities”) and (2) the TCEH Companies (the
“SpinCo Policy Liabilities”). 
 (b) Each of the Company and SpinCo acknowledge and agree that (i) the
Company Policy Liabilities and all costs, fees and expenses under the Letters of Credit identified on Annex A attached hereto (the “Split Letters of Credit”) (including any draws on the Split Letters of Credit in respect
of the Company Policy Liabilities and the costs of maintaining such Split Letters of Credit allocable to the Company Policy Liabilities) arising out of or resulting from the Company Policy Liabilities are Excluded Liabilities for all purposes
hereunder, and (ii) the SpinCo Policy Liabilities and all costs, fees and expenses arising out of or resulting from the SpinCo Policy Liabilities under the Split Letters of Credit (including any draws on the Split Letters of Credit in respect
of the SpinCo Policy Liabilities and the costs of maintaining such Split Letters of Credit allocable to the SpinCo Policy Liabilities) are TCEH Company Liabilities for all purposes hereunder. 

  
 25

efforts to, as promptly as practicable, provide for the termination, release and return of the Letters of Credit set forth on Annex B attached hereto (including any renewals or replacements thereof) (the “E-Side Letters of
Credit”) to SpinCo or its designee by providing adequate security to the applicable beneficiary of each E-Side Letter of Credit in the form of cash collateral, back-to-back letters of credit, a parent company guaranty or similar security as
necessary to obtain the return and cancellation of each E-Side Letter of Credit at or prior to the earlier of (A) the Effective Time (as defined in the Merger Agreement), and (B) the EFH Effective Date.

ASSIGNMENT AND ASSUMPTION AGREEMENT 

This Assignment and Assumption Agreement (this “Agreement”) is effective as of October [●], 2016, by and among Energy

limited liability company (“TCEH”), and TEX Energy LLC, a Delaware limited liability company (“SpinCo”). 

WHEREAS, TCEH is an indirect wholly owned subsidiary of the Company and SpinCo is a direct wholly owned subsidiary of TCEH; 

WHEREAS, the Company, EFCH or TCEH, as applicable, own the Acquired TCEH Assets (as defined in the Separation Agreement below) listed on
Schedule A hereto (the “Contributed Assets”); 
 WHEREAS, TCEH owns, directly or indirectly, all of the outstanding
equity interests of the entities listed on Schedule B hereto (the “TCEH Contributed Subsidiaries”); and 

WHEREAS, as contemplated by that certain Separation Agreement, dated as of the date hereof, by and between the Company, SpinCo, and TEX
Operations Company LLC, a Delaware limited liability company and indirect wholly owned subsidiary of TCEH (as amended, the “Separation Agreement”), (i) the Company, EFCH and TCEH, as applicable, desire to contribute, convey,
transfer and assign the Contributed Assets to SpinCo and, (ii) TCEH desires to contribute, convey, transfer and assign the TCEH Contributed Subsidiaries to SpinCo. 

NOW THEREFORE, in consideration of the mutual covenants set forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 1. Capitalized Terms. Capitalized terms
used herein and not defined herein have the meanings assigned to them in the Separation Agreement. 
 2. EFH Contribution. The
Company hereby contributes, conveys, transfers and assigns all of the Contributed Assets held by the Company (the “EFH Contributed Assets”) to TCEH, and TCEH hereby accepts such contribution, conveyance, transfer and assignment of
the EFH Contributed Assets (the “Initial EFH Contribution”). Effective immediately following the Initial EFH Contribution, TCEH hereby contributes, conveys, transfers and assigns each of the EFH Contributed Assets to SpinCo, and
SpinCo hereby accepts such contribution, conveyance, transfer and assignment from TCEH (the “Subsequent EFH Contribution,” and together with the Initial EFH Contribution, “EFH Contribution”). SpinCo hereby assumes
and agrees to pay, discharge, perform or otherwise satisfy as and when due all liabilities and obligations of any kind and nature, in each case, arising out of facts, circumstances, events or conditions in existence before, on or after the date
hereof of, under, related to, resulting from, or arising out of or in connection with, as applicable, the EFH Contributed Assets and all Assumed Liabilities (as defined in the Separation Agreement) (the “EFH Assumed Liabilities”).

 3. EFCH Contribution. EFCH hereby contributes, conveys, transfers and assigns all of the Contributed Assets held by EFCH (the
“EFCH Contributed Assets”) to TCEH, and TCEH hereby accepts such contribution, conveyance, transfer and assignment of the EFCH Contributed Assets (the “Initial EFCH Contribution”). Effective immediately following
the Initial EFCH Contribution, TCEH hereby 

 
contributes, conveys, transfers and assigns each of the EFCH Contributed Assets to SpinCo, and SpinCo hereby accepts such contribution, conveyance, transfer and assignment from TCEH (the
“EFCH Subsequent Contribution,” and together with the Initial EFCH Contribution, the “EFCH Contribution”). SpinCo hereby assumes and agrees to pay, discharge, perform or otherwise satisfy all liabilities and
obligations of any kind and nature arising out of or otherwise relating to the EFCH Contributed Assets. 
 4. TCEH Contribution. TCEH
hereby contributes, conveys, transfers and assigns the TCEH Contributed Subsidiaries and all of the Contributed Assets held by TCEH (the “TCEH Contributed Assets”) to SpinCo, and SpinCo hereby accepts such contribution, conveyance,
transfer and assignment (the “TCEH Contribution,” and together with the EFH Contribution and the EFCH Contribution, the “Contributions”). SpinCo hereby assumes and agrees to pay, discharge, perform or otherwise
satisfy all liabilities and obligations of any kind and nature arising out of or otherwise relating to the TCEH Contributed Assets and any other liabilities identified on Schedule C hereto (the “TCEH Assumed Liabilities,” and
together with the EFH Assumed Liabilities, the “Assumed Liabilities”). 
 5. Further Assurances. In furtherance of
the transactions described herein, the parties hereto shall, and shall cause their applicable subsidiaries to, execute such additional bills of sale, quitclaim deeds, stock or equity powers, certificates of title, assignments of contracts and other
instruments of transfer, conveyance and assignment and other documents reasonably necessary to evidence the transfer, conveyance and assignment of the Contributed Assets to SpinCo and the valid and effective assumption of the Assumed Liabilities by
SpinCo, including any which are not transferred on the date hereof as a result of Section 2.2(b) of the Separation Agreement or for any other reason. 

6. Tax Treatment. For federal income tax purposes, at the time of the Contributions, each of EFCH, TCEH and SpinCo is an entity that is
disregarded as separate from the Company, and accordingly, the Contributions will have no federal income tax effect. For Texas sales and use tax purposes, the Contributions will be treated as (i) a transfer of intangible assets not subject to
Texas sales and use tax, and/or (ii) a transfer of assets constituting a separate division, branch, or identifiable segment of a business that is exempt from Texas sales and use tax as an occasional sale. 

7. Counterparts. This Agreement may be executed in any number of counterparts (including by electronic means), each such counterpart
being deemed to be an original instrument, and all such counterparts taken together constituting one and the same agreement. 
 8.
Captions. The captions of the paragraphs herein are inserted for convenience of reference only and shall not be used in construing the terms and provisions hereof. 

9. Successors and Assigns. This Agreement shall be binding upon, and shall inure to the benefit of, the parties hereto and their

CONTEMPLATED HEREBY OR ANY RELIEF OR REMEDIES SOUGHT BY ANY PARTY, AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER, SHALL BE CONSTRUED, PERFORMED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ITS
PRINCIPLES OR RULES OF CONFLICT OF LAWS TO THE EXTENT SUCH PRINCIPLES OR RULES WOULD REQUIRE OR PERMIT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. Each of the parties hereto (i) submits

 
to the exclusive jurisdiction of the Bankruptcy Court; provided that if the Bankruptcy Court declines to accept jurisdiction over a particular Action, then the Chancery Court of the State of

hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any Action arising out of or relating to this Agreement or the
transactions contemplated hereby in any Delaware or federal court in accordance with the provisions of this Section. Each of the parties hereby irrevocably waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the
maintenance of such Action in any such court. Each of the parties hereby irrevocably and unconditionally consents to service of process in the manner provided for notices in the Separation Agreement. Nothing in this Agreement will affect the right
of any party to serve process in any other manner permitted by Law. 
 (b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY
ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR
INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (W) NO REPRESENTATIVE, 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, (X) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (Y) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND
(Z) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 

11. Limitations of Liability. The Liabilities of any party hereto arising out of or relating to this Agreement shall be limited
pursuant to and as provided in the Separation Agreement.

under the Separation Agreement of any Indemnified Party in their respective capacities as such, the provisions of this Agreement and the Separation Agreement are solely for the benefit of the parties hereto and thereto and their respective
successors and permitted assigns and are not intended to confer upon any Person, except the parties hereto and thereto and their respective successors and permitted assigns, any rights or remedies hereunder and there are no third party beneficiaries
of this Agreement or the Separation Agreement; and neither this Agreement nor the Separation Agreement shall provide any third party with any remedy, claim, liability, reimbursement, cause of action or other right in excess of those existing without
reference to this Agreement or the Separation Agreement. 
 13. Assignment. Neither party shall assign its rights or obligations
under this Agreement (by operation of law or otherwise) unless, such party concurrently assigns its rights and obligations under the Separation Agreement to the same assignee of its rights and obligations hereunder.

ASSIGNMENT AND ASSUMPTION AGREEMENT 

This Assignment and Assumption Agreement (the “Agreement”) is entered into effective as of October [●], 2016 (the
“Effective Date”) by and between Energy Future Holdings Corp., a Texas corporation (“EFH”), and TEX Operations Company LLC, a Delaware limited liability company (“OpCo”), and with respect to the
assignment of certain Agreements hereunder, EFH Corporate Services Company (“Corporate Services”), Luminant Generation Company LLC (“Luminant”), TXU Energy Retail Company, LLC (“Retail”), and Texas
Competitive Electric Holdings Company LLC (“TCEH”). Corporate Services, Luminant, Retail and TCEH are referred to herein as the “Agreement Parties”). 

RECITALS 
 WHEREAS,
EFH currently sponsors and maintains the employee benefit plans, programs and policies listed on Exhibit A attached hereto and made a part hereof (the “Contributed Plans”), and EFH and the Agreement Parties are parties
to the employment agreements listed on Exhibit A, as well as certain agreements relating to the operation and administration of the Contributed Plans (collectively, the “Agreements”); and 

WHEREAS, on April 29, 2014, EFH and certain entities in which it, directly or indirectly, held an equity interest, and certain of
their respective subsidiaries (collectively, the “Debtors”), commenced voluntary cases under Chapter 11 of Title 11 of the United States Code, 11 U.S.C. §101 et seq. (as amended, the “Bankruptcy
Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”), which cases are jointly administered for procedural purposes only under Case No. 14-10979 (collectively, with any
proceedings relating thereto, the “Chapter 11 Cases”); and 
 WHEREAS, on July 29, 2016, EFH, Energy Future
Intermediate Holding Company LLC, a Delaware limited liability company (“EFIH”), NextEra Energy, Inc., a Florida corporation (“Parent”), and EFH Merger Co., LLC, a Delaware limited liability company and direct
wholly owned subsidiary of Parent (“Merger Sub”), entered into that certain Agreement and Plan of Merger (as amended, the “Merger Agreement”), which provides for, among other things, the merger of EFH with and into
Merger Sub, with Merger Sub being the surviving company and the successor to EFH; and 
 WHEREAS, the Third Amended Joint Plan of
Reorganization filed by the Debtors with the Bankruptcy Court on July 29, 2016 (as amended, the “Plan of Reorganization”) provides that the confirmation and effective date of the Plan of Reorganization with respect to the TCEH
Debtors (as defined in the Plan of Reorganization) (“TCEH Effective Date”) may occur separate from, and independent of, the confirmation and effective date of the Plan of Reorganization with respect to the EFH Debtors (as defined in
the Plan of Reorganization); and 
 WHEREAS, effective as of August 29, 2016, the Bankruptcy Court entered an order (the
“Confirmation Order”) approving and confirming, among other things, the restructuring of the TCEH Debtors pursuant to the Plan of Reorganization, subject to certain contingencies set forth in the Confirmation Order, all of which
contingencies have, as of October 3, 2016, been satisfied or waived; and 
 WHEREAS, in connection with the implementation of
the Plan of Reorganization, all employees of EFH, and its affiliates (other than Oncor Electric Delivery Company, LLC and its direct and indirect subsidiaries), have been or will be transferred to OpCo (or an affiliate of OpCo) prior to the TCEH
Effective Date; and 

 WHEREAS, as provided for, and required under, the Plan of Reorganization and the Merger
Agreement, EFH desires to transfer and assign to OpCo the sponsorship (including the assumption of all assets and liabilities thereto) of each of the Contributed Plans and the Agreement Parties desire to transfer and assign its rights and
obligations under each Agreement to which it is a party, and OpCo desires to accept and assume all such transfers; and 
 WHEREAS,
the parties desire to enter into this Agreement to evidence and effectuate such transfer and assignment, and acceptance and assumption, of the Contributed Plans and the Agreements. 

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: 

1. Assignment and Assumption of Plans. Effective as of the TCEH Effective Date, the sponsorship and all obligations relating to the
maintenance and administration of each of the Contributed Plans are hereby transferred and assigned from EFH to OpCo, and OpCo hereby accepts such transfer and assignment. By virtue of such assignment and assumption, OpCo hereby possesses all
rights, authority, and responsibility as plan sponsor, employer and a participating employer and fiduciary under each of the Contributed Plans. Effective as of the TCEH Effective Date, OpCo hereby assumes full responsibility for the liabilities,
qualification, administration and compliance with all applicable legal requirements relating to each of the Contributed Plans, including without limitation the provision of all benefits due or required to be paid under the Contributed Plans
(including benefits accrued or which become payable prior to the Effective Date). 
 2. Assignment and Assumption of Agreements.
Effective as of the TCEH Effective Date, the rights and obligations of the Agreement Party under each of the applicable Agreements are hereby transferred and assigned from the applicable Agreement Parties to OpCo, and OpCo hereby accepts such
transfer and assignment. By virtue of such assignment and assumption, OpCo hereby possesses all rights and obligations of the applicable Agreement Parties under each of the Agreements. Effective as of the TCEH Effective Date, OpCo hereby assumes
full responsibility for the performance of all obligations of the Agreement Party under each of the applicable Agreements. EFH, the Agreement Party and OpCo shall reasonably cooperate with each other to cause each of the Contributed Plans and
Agreements to be amended, as necessary, to reflect the assignment, transfer and assumption evidenced hereby. To the extent that the transfer, acceptance and assignment of any of the Agreements require the consent of an individual employee, affiliate
or third party, as applicable, the parties shall reasonably cooperate to obtain such consent. 
 3. Plan Administrator. From and
after the TCEH Effective Date, the named fiduciary and plan administrator, as applicable, of each of the Contributed Plans shall be the applicable administrative committee, or other designee, of OpCo, which shall replace the applicable named
fiduciary and plan administrator of EFH in such capacity, and shall have all responsibility and authority necessary or appropriate to administer the Contributed Plans in accordance with their terms. All policies and decisions adopted by the
applicable EFH plan administrator prior to the TCEH Effective Date shall, unless and until changed by the applicable OpCo plan administrator, continue in effect. Without limiting the generality of the foregoing, all funding and investment policies,
loan, withdrawal and distribution procedures, procedures for processing domestic relations orders and qualified medical child support orders, procedures for processing claims, and any other policies or procedures relating to the administration of
any of the Contributed Plans, previously adopted by the applicable EFH plan administrator, shall remain in full force and effect unless and until changed by the applicable OpCo plan administrator. 

 4. Fidelity Bond; Liability Insurance. EFH and OpCo shall timely notify the issuer of any
fidelity bond or liability insurance policy relating to any Contributed Plan or Agreement of the transfer, assignment and assumption provided for herein, and the parties shall fully cooperate and take all action necessary to effectuate the transfer,
assignment and assumption with respect to such fidelity bonds and insurance policies so as to ensure coverage of OpCo, the applicable OpCo plan administrators and all entities and individuals involved in the administration of the Contributed Plans
and Agreements from and after the TCEH Effective Date. 
 5. Effect on Employment. It is the intent of the parties, that the transfer
of employment of employees from EFH, and certain of its affiliates (other than Oncor Electric Delivery Holdings Company, LLC and its subsidiaries), to OpCo shall be treated as a transfer of employment and not as a termination of employment for
purposes of any of the Contributed Plans. In this connection, each employee shall be treated as if his/her employment has not been terminated as a result of the transfer from EFH, or an affiliate of EFH, to OpCo, and his/her service, for all
purposes under each Contributed Plan and Agreement, shall be treated as continuous without any break in service related to such transfer. Notwithstanding the foregoing, consistent with the Plan of Reorganization, the Closing of the transactions
contemplated in the Plan of Reorganization shall be deemed to constitute a change in control of EFH for purposes of the applicable Contributed Plans. 

6. Employee Communications. OpCo shall be responsible for preparing and distributing summaries of material modifications and other
communication materials to notify employees of the assignment, transfer and assumption evidenced hereby. EFH shall cooperate with OpCo in the preparation of such materials as may be reasonably requested by OpCo. 

7. Reports to Governmental Agencies; Audits. From and after the TCEH Effective Date, OpCo shall be responsible for preparing, filing
and/or distributing all required governmental reports relating to the Contributed Plans including without limitation, Annual Returns/Reports (Form 5500 Series), Summary Annual Reports, Annual Funding Notices, and all filings required under the
Affordable Care Act. EFH shall, or shall cause its affiliates to, cooperate with OpCo, and provide OpCo with all information available to EFH or its affiliates, as OpCo may reasonably request, in connection with the preparation of such reports.
Additionally, in the event of a governmental audit, investigation or inquiry relating to any of the Contributed Plans, EFH and OpCo shall fully cooperate with each other, and EFH shall, or shall cause its affiliates to, provide OpCo with all
information or documentation in EFH’s, or its affiliates’ possession or control as may be reasonably requested by OpCo in connection with any such audit, investigation or inquiry. 

8. Transfer of Records. To the maximum extent allowed under applicable law, EFH shall, or shall cause its affiliates to, transfer to
OpCo all records pertaining to the Contributed Plans and Agreements in EFH’s, or its affiliates, possession or control as soon as reasonably practical following the Effective Date. 

9. No Plan Amendment. Except as expressly provided for herein, nothing in this Agreement shall be construed or deemed to constitute an
amendment to any Contributed Plan, and nothing in this Agreement shall limit, in any way, the right and authority of OpCo to amend each of the Contributed Plans, in whole or in part, from time to time. 

10. No Third Party Beneficiary. Nothing in this Agreement shall create any rights in any person or entity other than the parties
hereto, including without limitation any participant, beneficiary, dependent or other covered person under any Contributed Plan. 
 11.
Further Acts. The parties agree to take any and all further action and to execute any and all further documents as either of them may reasonably determine to be necessary or appropriate to effectuate the transfer, assignment and assumption of
the Contributed Plans and the Agreements, and all other matters contemplated in this Agreement. 

 12. Applicable Law. TO THE EXTENT NOT OTHERWISE GOVERNED BY FEDERAL LAWS SUCH AS ERISA AND
THE CODE (AS SUCH TERMS ARE DEFINED IN THE MERGER AGREEMENT) THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS OF THE STATE OF TEXAS. 

13. Binding Effect; Assignment. All of the terms and provisions of this Agreement shall be binding upon and inure to the benefit of,
and be enforceable by the parties hereto and their respective successors and permitted assigns. Neither party shall assign its rights or obligations under this Agreement (by operation of law or otherwise) unless such party concurrently assigns its
rights and obligations under the Separation Agreement to the same assignee of its rights and obligations hereunder. 
 14. Invalidity of
Provisions. In the event that one or more of the provisions contained in this Agreement shall be invalid, illegal or unenforceable in any respect under any applicable law, the validity, legality or enforceability of the remaining provisions
hereof shall not be affected or impaired thereby. 
 15. Entire Agreement. This Agreement, together with that certain Separation
Agreement, by and among EFH, OpCo and TEX Energy LLC, a Delaware limited liability company, dated as of the date hereof (the “Separation Agreement”), constitutes the whole and entire agreement between the parties hereto and
supersedes any prior agreement, undertaking, declaration, commitment or representation, verbal or oral, with respect to the subject matter hereof. 

16. Limitations of Liability. The liabilities of the parties hereto arising out of or relating to this Agreement shall be limited
pursuant to and as provided in the Separation Agreement. 
 17. Defined Terms. Capitalized terms not defined herein shall be given
the meaning ascribed to them in the Merger Agreement, Plan of Reorganization or Separation Agreement. In the event of a conflict between any such definitions, the definition in the Merger Agreement shall be controlling. 

18. Captions. The captions of the sections and paragraphs of this Agreement are for convenience and reference only and in no way
define, limit or describe the scope or intent of this Agreement. 
 IN WITNESS WHEREOF, the parties have caused this Agreement to be duly
executed as of the TCEH Effective Date.

Section 2.6 Aggregate Net Working Capital Adjustment Amount. 

(a) At least ten (10) Business Days prior to the scheduled Closing Date, Seller will prepare (at Seller’s expense) and deliver to
Buyer a worksheet setting forth Seller’s good faith estimate of the Aggregate Net Working Capital as of the Closing Date (the “Estimated Aggregate Net Working Capital Amount”), as well as a computation thereof (which
computation shall be prepared in accordance with GAAP applied on a basis consistent with the preparation of the Balance Sheet (provided that in the event of a conflict between GAAP and consistent application thereof, GAAP shall prevail), subject to
such difference in accounting principles, policies and procedures as are set forth on Exhibit C (the “Accounting Principles”)), together with a reasonably detailed explanation of, and documentation sufficient to
confirm the accuracy of the computation of, such Estimated Aggregate Net Working Capital Amount. Buyer shall have the right to reasonably and in good faith object to the amounts contained in Seller’s calculation of Estimated Aggregate Net
Working Capital Amount within three (3) Business Days after Seller’s delivery thereof to Buyer. Seller shall in good faith consider any such objections of Buyer and, if Buyer has made any reasonable objections, shall re-issue Seller’s
good faith estimate of the Estimated Aggregate Net Working Capital Amount no later than three (3) Business Days prior to the Closing Date with any such revisions that Seller has determined in good faith are appropriate. Notwithstanding the
foregoing, the failure of the Parties to agree on the Estimated Aggregate Net Working Capital Amount shall in no way delay the Closing and the Parties hereby agree that any pre-Closing disagreement with respect to the Estimated Aggregate Net Working
Capital Amount will be handled with the post-Closing adjustment mechanisms contained herein. If (i) the Estimated Aggregate Net Working Capital Amount is greater than the Aggregate Target Net Working Capital Amount, the Base Purchase Price
payable at Closing will be increased by an amount equal to the difference between the Estimated Aggregate Net Working Capital Amount minus the Aggregate Target Net Working Capital Amount; and (ii) the Estimated Aggregate Net Working Capital
Amount is less than the Aggregate Target Net Working Capital Amount, the Base Purchase Price payable at Closing will be decreased by an amount equal to the difference between the Aggregate Target Net Working Capital Amount minus the Estimated
Aggregate Net Working Capital Amount (such amount under either (i) or (ii) is referred to as the “Closing Date Aggregate Net Working Capital Adjustment Amount”). 

  
 5 

 (b) Within sixty (60) days after the Closing Date, Buyer will prepare (at Buyer’s
expense) and deliver to Seller a worksheet setting forth Buyer’s good faith computation of the actual amount of the Aggregate Net Working Capital as of the Closing Date (the “Proposed Aggregate Net Working Capital
Amount”), which computation shall be prepared in accordance with the Accounting Principles and on the same format as set forth on Exhibit C, together with a reasonably detailed explanation of, and documentation sufficient to
confirm the accuracy of the computation of, such Proposed Aggregate Net Working Capital Amount. If within forty-five (45) days following delivery of such worksheet and supporting documentation, Seller does not object in writing thereto to
Buyer, then the Proposed Aggregate Net Working Capital Amount shall constitute the actual amount of the Aggregate Net Working Capital as of the Closing Date for purposes of this Agreement (the “Final Aggregate Net Working Capital
Amount”). If, within forty-five (45) days following delivery of such worksheet and supporting documentation, Seller objects in writing thereto to Buyer (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 2.6(e) below. 
 (c) If the Proposed Aggregate Net Working Capital Amount is not prepared and delivered by Buyer within
the sixty (60) day period set forth in Section 2.6(b) above, Seller shall be entitled (but not obligated) during the forty-five (45) day period commencing on the sixty-first
(61st) day after the Closing Date to prepare (at Seller’s expense) and deliver to Buyer a worksheet setting forth Seller’s good faith computation of the Proposed Aggregate Net
Working Capital Amount, which computation shall be prepared in accordance with the Accounting Principles and on the same format as set forth on Exhibit C, and based upon information available to Seller, together with a reasonably detailed
explanation of, and documentation sufficient to confirm the accuracy of the computation of, such Proposed Aggregate Net Working Capital Amount. If within thirty (30) days following delivery of such worksheet and supporting documentation, Buyer
does not object in writing thereto to Seller, then the Proposed Aggregate Net Working Capital Amount submitted by Seller pursuant to this Section 2.6(c) shall constitute the Final Aggregate Net Working Capital Amount. If, within thirty
(30) days following delivery of such worksheet and supporting documentation, Buyer 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 2.6(e) below. 

(d) If neither Buyer nor Seller prepares and timely delivers a Proposed Aggregate Net Working Capital Amount in accordance with
Section 2.6(b) or Section 2.6(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 Buyer’s Proposed Aggregate Net Working Capital Amount pursuant to Section 2.6(b) or if Buyer
timely objects to Seller’s Proposed Aggregate Net Working Capital Amount pursuant to Section 2.6(c), then Buyer 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 2.6(b) or Section 2.6(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 Buyer 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. Buyer and Seller, and their respective Representatives, shall cooperate fully with the Neutral Auditor. The
Neutral Auditor, acting 

  
 6 

 
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 in accordance with the Accounting Principles). 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 Buyer and Seller. The Neutral Auditor shall be directed to resolve the disputed items and amounts and deliver to Buyer and Seller a written determination of the Final Aggregate Net
Working Capital Amount (such determination to made consistent with this Section 2.6(e), to include 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 Buyer or Seller) within thirty (30) days after being retained, which determination will be final, binding and conclusive on the Parties and their respective Affiliates, and their respective Representatives, successors
and assigns. Notwithstanding anything herein to the contrary, the dispute resolution mechanism contained in this Section 2.6(e) shall be the exclusive mechanism for resolving disputes, if any, regarding the Aggregate Net Working Capital,
if any, and neither Seller nor Buyer shall be entitled to indemnification pursuant to Article X for Losses reflected in the amount of the Aggregate Net Working Capital or the determination of Aggregate Net Working Capital. 

(f) The “Final Aggregate Net Working Capital Adjustment Amount” shall be calculated by computing the Closing Date
Aggregate Net Working Capital Adjustment Amount in accordance with Section 2.6(a), but substituting the 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 (positive or negative) 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 Buyer 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 Buyer 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 five (5) Business Days after the Final Aggregate Net Working Capital Amount is finally determined as provided in this Section 2.6(f)
and will be payable by wire transfer of immediately available funds to such account or accounts as shall be specified by Buyer or Seller, as applicable. Any payments made pursuant to this Section 2.6(f) shall be treated as an adjustment
to the Tax Allocation Purchase Price by the parties for Tax purposes, unless otherwise required by applicable Law. 
 (g) Following the
Closing, Seller and Buyer 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 the Acquired
Companies) as are reasonably requested in connection with the matters addressed in this Section 2.6. Consistent with the foregoing, following the Closing and until the finalization of the Final Aggregate Net Working Capital Adjustment
Amount pursuant to this Section 2.6, Buyer shall, at Seller’s expense, provide or provide reasonable access (in a manner not unreasonably disruptive to its business) to Seller or the Neutral Auditor (as applicable) 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. Seller and the Neutral Auditor shall be entitled to make reasonable inquiries and information
requests of 

  
 7 

 
Buyer regarding the worksheet setting forth the computation Amount and the calculations set forth therein, provided that, notwithstanding anything to the contrary in this
Section 2.6(g), such access shall not include (i) access to materials that are subject to the attorney-client, work-product or other similar privilege or (ii) access to any working papers of any independent accountant unless
customary confidentiality and hold harmless agreements have been first executed. 
 Section 2.7 Tax Treatment; Allocation of
Purchase Price. 
 (a) Buyer and Seller acknowledge that, since the Acquired Companies other than FPLE Forney and Lamar
are classified as entities disregarded from their owners for federal income tax purposes, and (b) an election pursuant to Section 338(h)(10) of the Code shall be made with respect to the acquisition of the membership interests in FPLE
Forney and Lamar, the purchase and sale of the Interests is intended to be treated for federal income tax purposes as a purchase and sale of the Assets and liabilities of the Acquired Companies. 

(b) Buyer shall prepare and provide to Seller within sixty (60) days after all adjustments to the Purchase Price pursuant to
Section 2.6 have been completed in accordance with the terms thereof, a schedule (the “Purchase Price Allocation Schedule”) allocating the amounts paid and the liabilities assumed in connection with the
transactions contemplated by this Agreement, adjusted as necessary to determine the purchase price of the Purchased Assets for federal income tax purposes (the “Tax Allocation Purchase Price”), among the Purchased Assets.

 (c) The Purchase Price Allocation Schedule shall be prepared in accordance with the general principles of Sections 338 and 1060 of the
Code and the Treasury Regulations pursuant thereto or any successor provision. Unless Seller objects to Buyer’s allocation schedule within thirty (30) days after receipt thereof, such schedule shall become final. If Seller objects to
Buyer’s allocation within thirty (30) days of receipt, then the Parties shall use Commercially Reasonable Efforts to agree, within thirty (30) days of Seller’s objection to the Purchase Price Allocation Schedule, to an allocation
of the Tax Allocation Purchase Price among the Assets of the Acquired Companies that is consistent with the allocation methodology provided by Sections 338 and 1060 of the Code and the Treasury Regulations promulgated thereunder (the
“Allocation”). In the event such mutual agreement cannot be achieved, Buyer shall engage a nationally-recognized accounting firm to serve as an independent valuation expert to determine the Allocation, the costs of which are
to be shared equally among Buyer, on the one hand, and Seller, on the other hand. Once the Allocation becomes final, whether by virtue of Seller’s deemed acquiescence, by express mutual agreement of the Parties, or by determination of the
independent valuation expert, the Parties agree that neither Buyer, Seller, nor any of their Affiliates shall take any position (whether in audits, Tax Returns or otherwise) that is inconsistent with such final Allocation. The Allocation shall be
revised to take into account subsequent adjustments to the Tax Allocation Purchase Price, including any indemnification payments (which shall be treated for Tax purposes as adjustments to the Purchase Price), in accordance with the provisions of
Sections 338 and 1060 of the Code and the Treasury Regulations pursuant thereto or any successor provision.

authorized by all necessary limited liability company action. This Agreement and the other Transaction Documents to which Buyer is a party have been duly and validly executed and delivered by Buyer and constitute or will constitute the legal, valid
and binding obligations of Buyer enforceable against Buyer in accordance with their terms. 
 Section 5.3 No Conflicts; Consents
and Approvals. The execution and delivery by Buyer of this Agreement and the other Transaction Documents to which Buyer is a party do not, and the performance by Buyer of its obligations under this Agreement and the Transaction Documents to
which Buyer is or will be a party will not: 
 (a) result in a violation or breach of any of the terms, conditions or provisions of the
Organizational Documents of Buyer; 

  
 18 

 (b) assuming all required Consents set forth in Schedule 5.3 (collectively, the
“Buyer Approvals”) have been made, obtained or given, result in a material violation of or a material breach of or default, or give rise to any right of termination, cancellation, material amendment or modification or
acceleration under any material Contract to which Buyer is a party, except for any such violations, breaches or defaults (or rights of termination, cancellation, material amendment or modification or acceleration) which would not, individually or in
the aggregate, reasonably be expected to have a material adverse effect on Buyer’s ability to perform its obligations under this Agreement or any of the other Transaction Documents to which Buyer is or will be a party; and 

(c) assuming all Buyer Approvals have been obtained or given, (i) result in a violation of, or breach any term or provision of, any Law
applicable to Buyer, except as would not have a material adverse effect on Buyer’s ability to perform its obligations under this Agreement or any other Transaction Document to which Buyer is a party or (ii) require any Consent of any
Governmental Authority under any applicable Law, other than such Consents which, if not made or obtained, would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on Buyer’s ability to perform its

or delay Buyer from performing its obligations hereunder. 
 (d) As of the Effective Date, there is no outstanding Order of, or
investigation pending, or to Buyer’s Knowledge, threatened by any Governmental Authority against Buyer the effect of any of which, individually or in the aggregate, would reasonably be expected to hinder, prevent or delay Buyer from performing

obligation to pay fees or commissions to any broker, finder or agent with respect to the transactions contemplated by this Agreement for which Seller could become liable or obligated. 

Section 5.7 Acquisition as Investment. Buyer is acquiring the Interests for its own account as an investment without the
present intent to sell, transfer or otherwise distribute the same to any other 

  
 19 

 
Person. Buyer has made, independently and without reliance on Seller (except to the extent that Buyer has relied on the express representations and warranties of Seller in this Agreement), its
own analysis of the Interests, the Acquired Companies, the Projects and the Purchased Assets for the purpose of acquiring the Interests, and Buyer has had reasonable and sufficient access to documents, other information and materials as it considers
appropriate to make its evaluations. Buyer acknowledges that the Interests are not registered pursuant to the Securities Act of 1933 (the “1933 Act”) and that none of the Interests may be transferred, except pursuant to an
applicable exemption under the 1933 Act. Buyer is an “accredited investor” as defined in Rule 501 promulgated under the 1933 Act. 

Section 5.8 Financial Resources. Buyer and its Affiliates have, and at the Closing, Buyer will have,
sufficient funds and other financial resources available to pay the Purchase Price and otherwise effect the transactions in accordance with this Agreement. Buyer acknowledges that receipt or availability of funds or financing by Buyer or any of its
Affiliates shall not be a condition to Buyer’s obligations hereunder. Buyer represents and warrants that all funds paid to Seller shall not have been derived from, or constitute, either directly or indirectly, the proceeds of any criminal
activity under the anti-money laundering laws of the United States.

its satisfaction an independent investigation and verification of the current condition and affairs of the Acquired Companies, the Purchased Assets and the Projects. In making its decision to execute this Agreement and to purchase the Interests,
Buyer has relied and will rely solely upon the results of such independent investigation and verification and the express representations, warranties, terms and conditions of this Agreement.

Employees. 
 Section 5.12 Regulatory Status. Buyer is authorized to acquire the Interests as provided for in this
Agreement under Section 203(a) of the Federal Power Act, 16 U.S.C. § 824b(a), pursuant blanket authorizations provided for in Section 33.1(c) of FERC’s regulations, 18 C.F.R. § 33.1(c).

required notices to, the applicable Governmental Authorities and (ii) cooperate in good faith with the applicable Governmental Authorities and provide promptly such other information and communications to such Governmental Authorities or other

(c) In furtherance of the foregoing covenants: 

(i) Each Party shall prepare, or with respect to any required HSR Act filings cause its ultimate parent entity (as that term is defined in

the filing fees under the HSR Act; 
 (ii) Neither Party shall, and each Party shall cause its Affiliates not to, take any action that

utility” as that term is defined under the Federal Power Act, as amended, including the regulations of the FERC thereunder, nor shall Buyer be, or take any action to become, a “public utility” as defined in this provision; 

  
 21 

 (iii) Subject to applicable confidentiality restrictions or restrictions required by Law, Buyer
and Seller will notify the other Party promptly upon the receipt of (A) any comments or questions from any officials of any Governmental Authority in connection with any filings made pursuant to this Section 6.1 or the transactions
contemplated by this Agreement and (B) any request by any officials of any Governmental Authority for amendments or supplements to any filings made pursuant to any Laws of any Governmental Authority or answers to any questions, or the
production of any documents, relating to an investigation of the transactions contemplated by this Agreement by any Governmental Authority. Whenever any event occurs that is required to be set forth in an amendment or supplement to any filing made
pursuant to this Section 6.1, each Party will promptly inform the other of such occurrence and cooperate in filing promptly with the applicable Governmental Authority such amendment or supplement. Without limiting the generality of the
foregoing, each Party shall provide to the other (or the other’s respective advisors) upon request copies of all correspondence between such Party and any Governmental Authority and any productions made by such Party or its Affiliates to any
Governmental Authority relating to the transactions contemplated by this Agreement. The Parties may, as they deem advisable and necessary, designate any competitively sensitive materials provided to the other under this Section 6.1 as
“outside counsel only.” Such materials and the information contained therein shall be given only to outside counsel of the recipient and will not be disclosed by such outside counsel to employees, officers, or directors of the recipient
without the advance written consent of the party providing such materials. In addition, to the extent reasonably practicable, all discussions, telephone calls, and meetings with a Governmental Authority regarding the transactions contemplated by
this Agreement shall include Representatives of both Parties. Subject to applicable Law, the Parties will consult and cooperate with each other in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, and proposals
made or submitted to any Governmental Authority regarding the transactions contemplated by this Agreement by or on behalf of any Party; and 

(iv) Buyer shall use all reasonable best efforts to take, in order to consummate the transactions contemplated by this Agreement, all actions

Agreement raised by any Governmental Authority, and (F) otherwise to obtain the Buyer Approvals in form and substance reasonably satisfactory to Seller and Buyer and to respond to and seek to resolve as promptly as reasonably practicable any
objections asserted by any Governmental Authority with respect to the transactions contemplated by this Agreement. Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement shall require (and reasonable best efforts as
used in this paragraph shall not require) Buyer to prevent the entry of any court order or to have vacated, lifted, reversed or overturned, or appeal, any decree, judgment, injunction or other order that would prevent, prohibit, restrict, or delay
the consummation of the transactions contemplated by this Agreement or to take or agree to undertake any action, including entering into any consent decree, hold separate order or other arrangement, that would (w) require the divestiture of any
Assets of Buyer, any of its Affiliates, or any of the Acquired Companies, (x) limit Buyer’s freedom of action with respect to, or its ability to consolidate and control, any of the Acquired Companies or any of their Assets or businesses or
any of Buyer’s or its Affiliates’ other Assets or Business, (y) limit Buyer’s ability to acquire or hold, or exercise full rights of ownership with respect to, the Interests or (z) require the payment of funds to any Person
(other than routine application fees payable to a Governmental Authority) (any of the foregoing clauses (w)-(z), 

  
 22 

 
unless specifically waived in writing by Buyer at its discretion, a “Burdensome Condition”). Without the prior written consent of Seller, which shall not be unreasonably
withheld, conditioned or delayed, Buyer shall not seek (or assist any other Person in seeking) to alter or enjoin the terms of, during the pendency of the Bankruptcy Cases, the Bankruptcy Court Order or the DIP Order in a manner that would
reasonably be expected to prevent Buyer from performing its obligations hereunder. 
 (d) Promptly following the Effective Date, Buyer will
seek authorization from the PUCT to acquire the Interests under Sections 39.158 and 39.154 of the PURA. 
 Section 6.2 Access of
Buyer. 
 (a) During the Interim Period, Seller will provide, and will cause the Acquired Companies to provide, Buyer and its
Representatives with reasonable access, upon reasonable prior notice (but in no event less than five (5) Business Days’ prior written notice) and during normal business hours, to the properties, books and records of the Acquired Companies
and the appropriate officers and employees of Seller and its Affiliates who have significant responsibility for one or more Acquired Companies, but only to the extent that such access does not unreasonably interfere with the business of Seller and
its Affiliates or the Businesses of the Acquired Companies, that such access is reasonably related to the requesting Party’s obligations and rights hereunder, and subject to compliance with applicable Laws and Seller’s or any of its
Affiliates’ safety policies, protocols and requirements; provided, however, that Seller shall have the right to (i) have a Representative present for any permitted communication with employees or officers of Seller or its Affiliates
and (ii) impose reasonable restrictions and requirements for safety purposes. Buyer shall be entitled, at its sole cost and expense, to have the Property surveyed and to conduct non-invasive physical inspections; provided, however, that
Buyer shall not be entitled to collect any air, soil, surface water or ground water samples nor to perform any invasive or destructive sampling on the Property. Promptly upon completion of any such entry, Buyer shall repair any damage caused by such
entry. Any disclosure to Buyer pursuant to the foregoing shall be subject to such disclosure (w) not violating any applicable Laws, (x) not resulting in the waiver of any attorney/client, work product, or similar privilege, (y) not
being of confidential information concerning the activities of Seller or its Affiliates (other than the Acquired Companies) that is unrelated to the Acquired Companies, the Business of any Acquired Company, or the Projects, or (z) not being of
proprietary models of Seller or any of its Affiliates pertaining to energy project evaluation, energy, natural gas, fuel oil or other fuel price curves or projections, or other economic predictive models. 

(b) During the Interim Period, in no event shall Buyer or any of Buyer’s Affiliates hold any meetings with, or otherwise communicate
with, any suppliers, other vendors or customers of any Acquired Company, or any Representatives of any Governmental Authority, regarding any Project or Acquired Company without the prior consent of Seller (which consent will not be unreasonably
withheld, conditioned or delayed). At any such meeting consented to by Seller, a Representative of Seller shall be entitled to participate therein. 

(c) Buyer assumes any and all risks of Loss associated with or arising out of the access and other rights under this Section 6.2,
and Buyer agrees to indemnify and hold harmless Seller, its Affiliates and their respective Representatives for any and all liabilities or Losses incurred by Seller, its Affiliates or their respective Representatives, or by any of Buyer’s
Representatives, for any injuries or property damage arising out of the access and other rights under this Section 6.2, caused by any of Buyer’s Representatives while present on the Property. 

(d) In connection with Buyer’s and its Affiliates financing activities during the Interim Period, Seller shall, and shall use
Commercially Reasonable Efforts to cause the Acquired 

  
 23 

 
Companies, and its and their respective Representatives, to provide to Buyer, at Buyer’s sole cost and expense, all cooperation reasonably requested by Buyer and that is customary in
connection with such financing activities; provided, however, that (i) nothing in this Section 6.2(d) shall require any cooperation to the extent that it would unreasonably interfere with the business or operations of
Seller or its Affiliates, including the Acquired Companies, or otherwise impair, in any material respect, the ability of any Representative of Seller or the Acquired Companies to carry out their respective duties as such and (ii) none of
Seller, its Affiliates or the Acquired Companies shall be required to pay any commitment or other similar fee for which it is not advanced funds or incur any other liability in connection with such financing activities. Buyer shall promptly, upon
request, reimburse Seller for all documented out-of-pocket costs and expenses (including reasonable advisor’s fees and expenses) incurred by Seller or its Affiliates, including the Acquired Companies, in connection with the cooperation provided
pursuant to this Section 6.2(d). All non-public information regarding Seller and its Affiliates provided to Buyer, its Affiliates or its Representatives pursuant to this Section 6.2(d)
shall be kept confidential by them in accordance with the Confidentiality Agreement, except for disclosure to potential lenders, investors, attorneys, accountants, rating agencies or their respective Representatives in connection with such financing
activities subject, where applicable, to customary confidentiality provisions as approved in advance in writing by Seller (which approval shall not be unreasonably withheld, conditioned or delayed). Buyer shall indemnify, defend and hold harmless
Seller, its Affiliates and their respective Representatives from and against any and all Losses actually suffered or incurred by Seller or any of its Affiliates, to the extent arising out of or relating to (i) any action taken or cooperation
provided by Seller or its Affiliates pursuant to this Section 6.2(d) or in connection with such financing activities or (ii) any information utilized in connection therewith (other than information provided to Buyer in writing by
Seller or the Companies). This Section 6.2(d) shall survive the termination of this Agreement. 
 Section 6.3 Certain
Restrictions. Except as required or permitted hereby, or as otherwise set forth in Schedule 6.3, during the Interim Period, Seller will cause the Acquired Companies and the Projects to operate in the ordinary course of business and
consistent with past practice. Without limiting the foregoing, except as otherwise set forth in Schedule 6.3, required or permitted hereby or required by applicable Laws or any Material Contract in effect as of the Effective Date or amended
as permitted hereby or as consented to by Buyer, which consent shall not be unreasonably withheld, conditioned or delayed (except that this Section 6.3 shall not restrict (i) the transfer of Excluded Items, (ii) the termination
or assignment of Excluded Contracts, (iii) the taking of any action otherwise listed below to the extent reasonably required to accomplish any of the Permitted Transactions or (iv) the termination of the services contemplated by
Section 6.8, and no consent of Buyer will be required with respect to any matter set forth in this Section 6.3 or elsewhere in this Agreement to the extent that the requirement of such consent would reasonably be expected to
violate any applicable Law), Seller will, during the Interim Period, cause the Acquired Companies not to:

(D) appointment of a receiver, trustee, custodian, conservator or other similar official for it or for all or any substantial part of its assets, or (ii) make a general assignment for the benefit of its creditors, or take any action in

Notwithstanding the foregoing, Seller may permit the Acquired Companies to take commercially reasonable actions with respect to emergency
situations so long as Seller shall, upon receipt of notice of any such actions, promptly inform Buyer of any such actions taken outside the ordinary course of business. 

Section 6.4 Use of Certain Names. Within forty-five (45) days following Closing, Buyer shall cause the Acquired
Companies to cease using the words “FPL”, “FPLE”, “ESI”, “NextEra”, “NextEra Energy”, “Energy Resources” and “FPL Energy” and any trademark confusingly similar thereto or
constituting an abbreviation thereof, and any logos associated therewith (the “Seller Marks”), including eliminating or covering the Seller Marks from the Property and Purchased Assets and disposing of any unused stationery
and literature of the Acquired Companies bearing the Seller Marks, and thereafter, Buyer shall not, and shall cause the Acquired Companies and their Affiliates not to, use the Seller Marks or any logos, trademarks or trade names belonging to Seller
or any Affiliate thereof, and Buyer acknowledges that it, its Affiliates and the Acquired Companies have no rights whatsoever to use such Intellectual Property. Without limiting the foregoing: 

(a) Within ten (10) days after the Closing Date, Buyer shall cause any Acquired Company whose name contains any of the Seller Marks to
change its name to a name that does not contain any of the Seller Marks. 
 (b) Within sixty (60) days after the Closing Date, Buyer
shall provide evidence that is reasonably acceptable to Seller, that Buyer has made all filings required pursuant to paragraph (a) above with, and has provided notice to, all applicable Governmental Authorities and all counterparties to the
Material Contracts regarding the sale of the Acquired Companies and the Purchased Assets to Buyer and the new addresses for notice purposes. 

Section 6.5 Support Obligations. 

(a) With respect to the NEER Guaranty, during the Interim Period, Seller and Buyer shall, and Buyer shall cause Buyer’s Affiliates to, use
their respective Commercially Reasonable Efforts to work together to procure the full and unconditional release, effective as of the Closing Date, of NEER’s obligations under the NEER Guaranty. For purposes of this subsection, Commercially
Reasonable Efforts shall require (i) jointly approaching Kinder Morgan to discuss and negotiate alternative arrangements for satisfying Kinder Morgan’s credit support requirements, and (ii) in support of any such alternative credit
support arrangements, Buyer offering to replace the NEER Guaranty with a substitute guarantee from Buyer or Buyer Parent Guarantor on terms acceptable to Kinder Morgan (provided that the maximum principal amount guaranteed may not be increased) and,
if the foregoing is not accepted by Kinder Morgan, Buyer or Buyer Parent Guarantor offering to deliver to Kinder Morgan 

  
 26 

 
a letter of credit from a creditworthy United States bank acceptable to Kinder Morgan for the account of Buyer or Buyer Parent Guarantor as applicant in an amount (x) sufficient to cover the
entire amount that may be payable under the NEER Guaranty or (y) such lesser amount deemed sufficient by Kinder Morgan, and, if such offer is accepted by Kinder Morgan, providing such letter of credit to Kinder Morgan in connection with the
Closing. 
 (b) If Buyer and Seller are not successful in obtaining the complete and unconditional release of NEER from its obligations
under the NEER Guaranty prior to Closing as contemplated in Section 6.5(a), then Seller or its Affiliates, as applicable, shall cause NEER to keep in place the NEER Guaranty, and Buyer shall deliver to Seller at the Closing, and shall
keep in place, an irrevocable, standby letter of credit in form and substance reasonably satisfactory to Seller and in an amount equal to the maximum amount of exposure under the NEER Guaranty and issued by Citibank N.A. pursuant to Buyer Parent
Guarantor’s debtor-in-possession credit agreement authorized by the DIP Order or another irrevocable, standby letter of credit on substantially similar terms from a creditworthy financial institution reasonably acceptable to Seller (the
“Continuing Support Letter of Credit”); provided, however, that as a condition to the continuing maintenance of the NEER Guaranty: 

(i) From and after the Closing, Buyer hereby agrees to indemnify and hold harmless Seller and its Affiliates from and against any and all
Losses that may be suffered, incurred or sustained by any of them or to which any of them become subject, resulting from, arising out of or relating to the NEER Guaranty being in effect on or after the Closing Date (including as a result of any draw
or demand for or making of any payment by NEER under the NEER Guaranty) with respect to the full extent of the NEER Guaranty. In furtherance, and not limitation, of the forgoing, if the NEER Guaranty is drawn upon in accordance with its terms after
the Closing Date, upon receipt of written notice thereof from Seller, Buyer shall pay Seller or its designee the amount so drawn upon in accordance with its terms within five (5) Business Days after the date of such written notice. If Buyer
fails to pay Seller or its designee within such five (5) Business Day period, Seller may draw upon or otherwise enforce the terms of the Continuing Support Letter of Credit in accordance with the terms thereof; 

(ii) from and after the Closing, Buyer and Seller shall continue to use Commercially Reasonable Efforts to obtain the full and unconditional
release of NEER from its obligations under the NEER Guaranty as contemplated by Section 6.5(a); and 
 (iii) Buyer shall not,
and shall cause the Acquired Companies not to, effect any amendments or modifications or any other changes to the Contracts or obligations to which any of the obligations under the NEER Guaranty relates to the extent such amendment or modification
would increase the liability of NEER under the NEER Guaranty or extend the stated maturity of any obligation to which the NEER Guaranty relates, without Seller’s prior written consent (which consent may be withheld in its sole and absolute
discretion). 
 (c) If a Continuing Support Letter of Credit is provided pursuant to Section 6.5(b), at the expiration or
termination of the NEER Guaranty (such that it is no longer subject to restoration or reinstatement), Seller shall deliver or cause to be delivered to Buyer the Continuing Support Letter of Credit for cancellation. 

Section 6.6 Excluded Items. Notwithstanding anything in this Agreement to the contrary, Buyer and Seller agree that the
Purchased Assets shall exclude those items listed on Schedule 6.6 (the “Excluded Items”). Seller shall retain all benefits and liabilities with respect to the Excluded Items, and Seller shall, prior to the Closing
Date, use Commercially Reasonable Efforts to cause the Acquired Companies to distribute, transfer or assign each Excluded Item to Seller or a Non-Acquired Company Affiliate. Buyer acknowledges that the inability of Seller to have any Excluded Item
distributed, 

  
 27 

 
transferred or assigned from any Acquired Company for any reason shall not delay Closing and any Excluded Item that Seller is unable to so distribute, transfer or assign by the Closing shall be
referred to as a “Non-Transferred Excluded Item.” As soon as is reasonably practicable after the Closing Date, at Seller’s cost and expense, the Parties will take such actions as are reasonably required to cause the
transfer to Seller or a Non-Acquired Company Affiliate of the Non-Transferred Excluded Items, and the removal thereof from the sites of the Projects, if applicable. From and after the Closing, except as set forth in the immediately preceding
sentence, Buyer and its Affiliates (including the Acquired Companies) shall have no obligations with respect to the Non-Transferred Excluded Items, including any obligation to preserve or protect the Non-Transferred Excluded Items. 

Section 6.7 Employee and Employee Benefit Matters. 

(a) During the Interim Period, the Project Employees who are providing services directly relating to the Projects may, in Seller or Seller
Affiliate’s sole discretion, continue in the same role following Closing as employees of Seller or a Seller Affiliate. Nothing in this Section 6.7 shall affect the right of Seller, or any Affiliate of Seller, to terminate the
employment of any Project Employee for any reason or at any time. At all times prior to Closing, Seller, or an Affiliate of Seller, shall continue to have the exclusive right to control the Project Employees and make any and all employment decisions
regarding Project Employees as it shall deem appropriate. Seller or its Affiliates shall be exclusively responsible for the payment of all wages, provision of all benefits and compliance with all applicable Laws with respect to the Project Employees
until such Project Employees are no longer employed by Seller or its Affiliates. 
 (b) Except as expressly contemplated herein or in the
O&M Agreement, from the Effective Date through the latter of a period of two (2) years from and after the O&M Expiration or the date of termination of this Agreement (pursuant to Section 9.1 if a Closing does not occur
hereunder), Buyer agrees not to solicit for hire or employment or employ, and to use Commercially Reasonable Efforts to cause Buyer Service Companies and their Affiliates not to solicit for hire or employment or employ, any Project Employee, without
Seller’s prior written consent; provided, however, that the restrictions set forth in this Section 6.7(b) shall not apply to any solicitation (or any hiring as a result of any solicitation) that consists of advertising in a
newspaper or periodical of general circulation or through similar general circulation on the internet or otherwise not specifically directed toward any Project Employee. 

Section 6.8 Termination of Certain Services, Excluded Contracts and Other Affiliate Transactions. Notwithstanding anything
in this Agreement to the contrary and except as contemplated with respect to the Contracts listed on Part I of Schedule 6.8 (the “Existing Affiliate Contracts”) and as contemplated in the O&M Agreement, the Energy
Management Agreement or the Transition Services Agreement, prior to the Closing, Seller shall, or shall cause an Affiliate of Seller, as applicable, to (i) terminate, sever, or assign to Seller or a Non-Acquired Company Affiliate effective upon
or before the Closing any services provided to any of the Acquired Companies by Seller or a Non-Acquired Company Affiliate, including the severance of the Acquired Companies from the insurance policies of the Non-Acquired Company Affiliates
(including those policies referred in Section 6.10, in accordance with Section 6.10), Tax services, legal services and banking services (to include the severance of any centralized clearance accounts) in each case for periods
prior to the Closing, (ii) (A) use Commercially Reasonable Efforts to terminate or assign to Seller or a Non-Acquired Company Affiliate each Contract listed on Part II of Schedule 6.8 as specified therein and (B) terminate or
assign all Contracts between any Acquired Company and Seller or any Non-Acquired Company Affiliate (collectively such Contracts described in this clause (ii), the “Excluded Contracts”), and (iii) release the applicable
Acquired Company from any and all liability under the applicable Excluded Contract, in each case without any liability of any kind on the part of any Acquired Company arising from any such termination, severance,

  
 28 

 
assignment or otherwise. In addition to the foregoing, prior to the Closing, any liability of an Acquired Company to Seller or a Non-Acquired Company Affiliate, or any receivable from an Acquired
Company to Seller or a Non-Acquired Company Affiliate, shall be satisfied or otherwise eliminated in full. 
 Section 6.9 Spare
Parts. Notwithstanding anything in this Agreement to the contrary, as may be permitted under the Project Financing Documents, prior to the Closing, Seller shall have the right to use Spare Parts in the ordinary course of business of the
Acquired Companies or in connection with the activities of any Project, in each case consistent with past practice. Prior to the Closing, Seller shall cause the then current inventory of the Spare Parts to be owned by the Acquired Companies. 

Section 6.10 Insurance. Seller shall maintain or cause to be maintained in full force and effect insurance coverage
consistent with past practice for the Acquired Companies until the Closing. From and after the Closing, all such insurance coverage for the Acquired Companies and the Purchased Assets relating to periods subsequent to the Closing shall no longer be
provided or maintained for any of the Acquired Companies or such Purchased Assets. For the avoidance of doubt, the Acquired Companies and the Purchased Assets will continue to be insured under any occurrence based third party liability policies
under which they were insured prior to Closing for any claims which relate to events or circumstances prior to Closing, without regard to when such claim is reported to the Acquired Companies and Purchased Assets. Buyer shall be solely responsible
for providing insurance to the Acquired Companies after the Closing. If any claims are actually made prior to the Closing Date under any liability insurance policy for any of the Acquired Companies, or if there are any matters reportable under any
claims made liability insurance policy for events or circumstances relating to pre-Closing events which are known to Seller, then Seller shall use Commercially Reasonable Efforts to ensure that the applicable Acquired Company can file, notice and
otherwise continue to pursue such claims and recover proceeds under the terms of such policies, and Seller will promptly pay over to the applicable Acquired Company any proceeds of any insurance recovery under any such policy by Seller. If any
casualty loss occurs prior to the Closing which is insured under any property or casualty insurance policy for any of the Acquired Companies and claims associated with such losses have been made prior to the Closing, then Seller shall use
Commercially Reasonable Efforts to ensure that the applicable Acquired Company can file, notice and otherwise continue to pursue such claims and recover proceeds under the terms of such policies and reasonably cooperate with the filing and pursuit
of any such claim, and Seller will promptly pay over to the applicable Acquired Company any such proceeds of any insurance recovery under any such policy by Seller, other than any such proceeds that have been applied to repair or replace the
property subject to such claim. 
 Section 6.11 Casualty. If any of the Purchased Assets are damaged or destroyed by
casualty loss during the Interim Period, and the sum of (a) the cost of restoring such damaged or destroyed Purchased Assets to a condition reasonably comparable to their prior condition, and (b) the net present value (calculated using the
Discount Rate) of the amounts of any lost net revenues reasonably expected to accrue after the Closing as a result of such damage or destruction to such Purchased Assets, (a) and (b) above as estimated by a qualified firm reasonably
acceptable to Buyer and Seller (and with the costs of such firm being paid by Buyer and Seller in equal proportion), and such sum being net of and after giving effect to any insurance proceeds available to the Acquired Companies for such restoration
and lost profits and any Tax benefits to the Acquired Companies related thereto (such sum, the “Restoration Cost” and the date of such estimation, the “Restoration Cost Estimation Date”), is greater
than $15,000,000 but does not exceed $131,303,723, Seller may elect either (i) to restore, repair or replace such damaged or destroyed Purchased Assets to a condition reasonably comparable to their prior condition (any of the foregoing, a
“Restoration,” and Seller’s election of a Restoration, the “Restoration Option”), or (ii) reduce the amount of the Purchase Price by such Restoration Cost. If Seller elects the
Restoration Option, it shall notify Buyer of such election in writing, and Seller shall use its Commercially Reasonable Efforts to complete, or cause to be completed, such Restoration prior to the Closing, and if the Restoration

  
 29 

 
can be completed on or before the date that is one hundred eighty (180) days after the Outside Date (the “Extended Outside Date”), the Closing Date shall be postponed
for the amount of time reasonably necessary to complete such Restoration; provided, however, that if the Closing Date is so extended and such Restoration is not completed in full by the Extended Outside Date, the Closing shall occur on
or before the Extended Outside Date and the Purchase Price will be reduced by the amount of the remaining Restoration Cost as of the Closing (as estimated by a qualified firm reasonably acceptable to Buyer and Seller); provided,
further, that if Seller elects the Restoration Option, Buyer shall be entitled to waive Seller’s obligation to complete the Restoration at any time within twenty (20) days following Seller’s written notice to Buyer of such
election by written notice to Seller and proceed to Closing upon satisfaction or waiver of the conditions to Closing set forth in Article VII and Article VIII, in which case Seller shall pay the applicable insurance proceeds with
respect to such casualty to Buyer promptly upon receipt and such casualty loss shall not affect the Closing. If Seller elects the Restoration Option or to reduce the Purchase Price, such casualty loss shall not affect the Closing. If Seller does not
provide Buyer written notice of its election within forty-five (45) days after the applicable Restoration Cost Estimation Date (but in any event at least twenty (20) days prior to the Closing Date), Buyer may elect to terminate this
Agreement within ten (10) Business Days after the end of such forty-five (45) day period by written notice to Seller. If the Restoration Cost is in excess of $131,303,723, Seller may, by written notice to Buyer within forty-five
(45) days after the applicable Restoration Cost Estimation Date (but in any event at least twenty (20) days prior to the Closing Date), elect to (i) reduce the Purchase Price by the estimated Restoration Cost or (ii) terminate
this Agreement, in each case by providing written notice to Buyer; provided, however, that if Seller does not elect to terminate this Agreement as provided in this sentence, then Buyer may elect, by written notice to Seller, to
terminate this Agreement within ten (10) Business Days of receipt by Buyer of Seller’s notice regarding its election. If the Restoration Cost is $15,000,000 or less, (A) Seller shall not be obligated to repair or replace the damaged
or destroyed Purchased Assets (but shall be obligated to cooperate in the pursuit of any applicable insurance proceeds in accordance with Section 6.10), (B) there shall be no reduction in the amount of the Purchase Price, and
(C) neither Buyer nor Seller shall have the right or option to terminate this Agreement and such casualty event shall not affect the Closing. Any cash insurance proceeds received by the Acquired Companies with respect to any casualty subject to
this Section 6.11 shall be disregarded for purposes of any Aggregate Net Working Capital calculation hereunder. 

Section 6.12 Condemnation. If any of the Purchased Assets are taken by condemnation during the Interim Period and the sum
of (a) the value of such Purchased Assets in a condemnation proceeding and (b) to the extent not included in the preceding clause (a), the net present value (calculated using the Discount Rate) of the amounts of any lost net revenues
reasonably expected to accrue after the Closing as a result of such condemnation of such Purchased Assets, (a) and (b) above as determined by a qualified firm reasonably acceptable to Buyer and Seller (and with the costs of such firm being
paid by Buyer and Seller in equal proportion), and such sum being net of and after giving effect to any condemnation award proceeds to be paid to the Acquired Companies and any Tax benefits to the Acquired Companies related thereto (such sum, the
“Condemnation Value” and the date of such estimation, the “Condemnation Value Estimation Date”), is greater than $15,000,000 but do not have a Condemnation Value in excess of $131,303,723, Seller may
elect either (i) to replace the Purchased Assets that were taken by such condemnation with reasonably comparable Assets, or (ii) to reduce the Purchase Price by such Condemnation Value (less, to the extent not taken into account in
calculating the Condemnation Value, the amount of any condemnation award proceeds to be paid to the Acquired Companies and any Tax benefits to the Acquired Companies related thereto). If Seller elects to replace the Purchased Assets or reduce the
Purchase Price, such condemnation shall not affect the Closing. If Seller does not provide Buyer notice of its election within forty-five (45) days after the applicable Condemnation Value Estimation Date (but in any event at least twenty
(20) days prior to the Closing Date), Buyer may elect to terminate this Agreement within ten (10) Business Days after the end of such forty-five (45) day period by written notice to Seller. If the Condemnation Value is in excess of

  
 30 

 
$131,303,723, Seller may, by written notice to Buyer within forty-five (45) days after the applicable Condemnation Value Estimation Date (but in any event at least twenty (20) days
prior to the Closing Date), elect to (a) reduce the Purchase Price by such Condemnation Value less, to the extent not taken into account in calculating the Condemnation Value, the amount of any condemnation award proceeds to be paid to the
Acquired Companies and any Tax benefits to the Acquired Companies related thereto), or (b) terminate this Agreement, in each case by providing written notice to Buyer; provided, however, that if Seller does not elect to terminate
this Agreement as provided in this sentence, then Buyer may, by written notice to Seller, terminate this Agreement within ten (10) Business Days of receipt by Buyer of Seller’s notice regarding its election. If the Condemnation Value is
$15,000,000 or less, (A) Seller shall not have the obligation to replace the Purchased Assets (but shall be obligated to cooperate in the pursuit of any applicable condemnation proceeds), (B) there shall be no reduction in the amount of
the Purchase Price, and (C) neither Buyer nor Seller shall have the right or option to terminate this Agreement and such condemnation shall not affect the Closing. Any condemnation proceeds received by the Acquired Companies with respect to any
condemnation subject to this Section 6.12 shall be disregarded for purposes of any Aggregate Net Working Capital calculation hereunder. 

Section 6.13 Transfer Taxes. Seller and Buyer shall each pay any Transfer Taxes imposed on it or any Acquired Company by
Law as a result of the transactions contemplated by this Agreement, but, notwithstanding any such requirement of Law, each of Seller and Buyer shall bear half of the total of all such Transfer Taxes. Accordingly, if either Party is required at Law
to pay more than its half of any such Transfer Taxes, the other Party shall promptly reimburse such first Party for amounts in excess of such half. Seller and Buyer shall timely file their own Transfer Tax Returns as required by Law and shall notify
the other Party when such filings have been made. Seller and Buyer shall cooperate and consult with each other prior to filing such Transfer Tax Returns to ensure that all such returns are filed in a consistent manner. Without limiting the
foregoing, Buyer shall be solely responsible for any Transfer Taxes arising from any action to dissolve, terminate or restructure any Acquired Company or to convey, distribute or transfer any Assets or other rights by deed, bill of sale or otherwise
to or from any Acquired Company on or after the Closing. 
 Section 6.14 Tax Matters. Except as provided in
Section 6.13 relating to Transfer Taxes: 
 (a) With respect to any Tax Return covering a taxable period ending on or before the
Closing Date (a “Pre-Closing Taxable Period”) that is required to be filed after the Closing Date with respect to any Acquired Company, (i) Seller shall cause such Tax Return to be prepared and shall deliver such Tax
Return as so prepared to Buyer not later than seven (7) days prior to the due date for filing such Tax Return, and (ii) Buyer shall cause such Tax Return to be executed and duly and timely filed with the appropriate Taxing Authority and
shall, subject to Section 6.14(b), pay all Taxes due with respect to the period covered by such Tax return. For the avoidance of doubt, the immediately preceding sentence shall not apply to income Tax Returns that report the income and
deductions of any Acquired Company for a Pre-Closing Taxable Period but that are required to be filed by a Person that is a direct or indirect owner of such Acquired Company but that is not itself an Acquired Company; such income Tax Returns shall
be filed by such Person and shall not be provided to Buyer. With respect to any Tax Return covering a taxable period beginning on or before the Closing Date and ending after the Closing Date (a “Straddle Taxable Period”) that
is required to be filed after the Closing Date with respect to an Acquired Company, (A) Buyer shall cause such Tax Return to be prepared (in a manner consistent with practices followed in prior taxable periods, except as required by applicable
Law or a change in Law) and shall deliver a draft of such Tax Return to Seller for Seller’s review and approval at least fourteen (14) days prior to the due date for filing such Tax Return, (B) Seller and Buyer shall cooperate and
consult with each other in order to finalize such Tax Return, and (C) thereafter Buyer shall cause such Tax Return to be executed and duly and timely filed with the appropriate Taxing Authority and shall, subject to Section 6.14(b),
pay all Taxes due with respect to the period covered by such Tax Return. 

  
 31 

 (b) As between Seller and Buyer, Seller shall be responsible for and indemnify Buyer against any
Tax with respect to an Acquired Company that is attributable to a Pre-Closing Taxable Period or to that portion of a Straddle Taxable Period that ends on the Closing Date, in each case to the extent that such Tax exceeds the amount (if any)
reflected as a current liability for such Tax pursuant to the Final Aggregate Net Working Capital Adjustment Amount computation in accordance with Section 2.6. Within five (5) days prior to the due date for the payment of any such
Tax, if (i) the amount of such Tax for which Seller is responsible, exceeds (ii) the amount reflected as a current liability for such Tax in such Final Aggregate Net Working Capital Amount, Seller shall pay to Buyer an amount equal to such
excess; if the amount described in clause (ii) exceeds the amount described in clause (i), Buyer shall pay to Seller the amount of such excess. With respect to a Straddle Taxable Period, Seller shall determine the Tax attributable to the
portion of the Straddle Taxable Period that ends on the Closing Date by an interim closing of the books of the relevant Acquired Company as of the Closing Date, except for ad valorem or property Taxes (“Property Taxes”) and
franchise Taxes based solely on capital which shall be prorated on a daily basis to the Closing Date (such that the Property Taxes or franchise Taxes attributable to the pre-Closing portion of a Straddle Taxable Period shall be equal to the amount
of such Taxes for such entire Straddle Taxable Period multiplied by a fraction, the numerator of which is the number of days during the Straddle Taxable Period that are in the Pre-Closing Taxable Period and the denominator of which is the actual
number of days in the Straddle Taxable Period). For this purpose, any franchise Tax paid or payable not based solely on capital with respect to such Acquired Company shall be allocated to the taxable period for which the income, operations, Assets
or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another period is obtained by the payment of such Tax. 

(c) Buyer shall be responsible for and indemnify Seller and its applicable Affiliates against, and Buyer shall be entitled to all refunds
(including, but not limited to, property tax refunds) and credits of, all Taxes of any Acquired Company that are not the responsibility of Seller pursuant to Section 6.14(b). 

(d) With respect to any Tax for which Seller is responsible, Seller shall have the right, at its sole cost and expense, to initiate any claim
for refund and to control (in the case of a Pre-Closing Taxable Period) or participate in (in the case of a Straddle Taxable Period) the prosecution, settlement or compromise of any proceeding involving such Tax, including the determination of the
value of property for purposes of real and personal property ad valorem Taxes; provided, however, that to the extent that any such claim or proceeding could reasonably be expected to have a post-Closing impact on Buyer or on any of the
Acquired Companies (a) Buyer shall be entitled to participate in such proceeding and (b) Seller shall not initiate, settle or otherwise compromise such proceeding without Buyer’s written consent, such consent not to be unreasonably
withheld or delayed. Buyer shall (and shall cause the relevant Acquired Company to) take such action in connection with any such proceeding as Seller shall reasonably request from time to time to implement the preceding sentence, including the
selection of counsel and experts and the execution of powers of attorney. Buyer shall (and shall cause the relevant Acquired Company to) give written notice to Seller of its receipt of any notice of any audit, examination, claim or assessment for
any Tax for which Seller is responsible within ten (10) days after its receipt of such notice; failure to give any such written notice within such ten (10) day period shall cause Buyer to forfeit any rights it may have by reason of
Section 4.10 or this Section 6.14 to the extent Seller is actually prejudiced by such failure. 
 (e) Seller shall
grant to Buyer (or its designees) access at all reasonable times to all of the information, books and records relating to the Acquired Companies within the possession of 

  
 32 

 
Seller (including workpapers and correspondence with Taxing Authorities), and shall afford Buyer (or its designees) the right (at Buyer’s expense) to take extracts therefrom and to make
copies thereof, to the extent reasonably necessary to permit Buyer (or its designees) to prepare Tax Returns, respond to Tax audits and investigations, prosecute Tax protests, appeals and refund claims and to conduct negotiations with Taxing
Authorities. The previous sentence shall, under no circumstances, be construed to grant Buyer access to the consolidated United States federal income tax or any consolidated or unitary state Tax Returns which include Seller or any of its Affiliates
for any taxable year. Buyer shall grant or cause the Acquired Companies to grant to Seller (or its designees) access at all reasonable times to all of the information, books and records relating to the Acquired Companies within the possession of
Buyer (including workpapers and correspondence with Taxing Authorities) and to the employees of the Acquired Companies, and shall afford Seller (or its designees) the right (at Seller’s expense) to take extracts therefrom and to make copies
thereof, to the extent reasonably necessary to permit Seller (or its designees) to prepare Tax Returns, respond to Tax audits and investigations, prosecute Tax protests, appeals and refund claims and to conduct negotiations with Taxing Authorities.
After the Closing Date, Seller and Buyer will preserve all information, records or documents in their respective possessions relating to liabilities for Taxes of the Acquired Companies until six (6) months after the expiration of any applicable
statute of limitations (including extensions thereof) with respect to the assessment of such Taxes. 
 (f) If after the Closing Buyer or any
Acquired Company actually receives a refund of any Tax or utilizes a credit for any overpayment of any Tax of any Acquired Company for a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date, Buyer shall
pay to Seller within ten (10) Business Days after such receipt or utilization an amount equal to such refund received or credit utilized, together with any interest received or credited thereon to the extent that such refund or credit exceeds
the amount (if any) reflected as a current asset for such refund or credit pursuant to the Final Aggregate Net Working Capital Adjustment Amount computation in accordance with Section 2.6. Buyer shall, and shall cause the relevant
Acquired Company to, take such action to obtain a refund of any Tax or a credit for any overpayment of any Tax of such Acquired Company for a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date or to
mitigate, reduce or eliminate any such Tax that could be imposed for a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date (including with respect to the transactions contemplated hereby) as is
reasonably requested by Seller; provided, however, for the avoidance of doubt and without limitation, that Buyer’s obligation to cooperate with Seller’s reasonable requests to mitigate, reduce or eliminate any Tax for a
Pre-Closing Taxable Period shall not be construed to require Buyer to carryback net operating losses or other tax attributes that arise following the Closing to a Pre-Closing Taxable Period or to take any other similar action that could have a
negative impact on Buyer. 
 (g) In the event that Seller initiates a claim for refund from a Taxing Authority with regard to any Tax of any
Acquired Company attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date, whether the initiation of such claim begins prior to or after the Closing, Seller shall have all rights to and
interest in such refund. Buyer shall, upon request, provide Seller a limited power of attorney allowing Seller to pursue such claim for refund with and collect such refund from such Taxing Authority. If after the Closing Buyer or any Acquired
Company receives a refund or utilizes a credit of any such Tax with regard to a claim so initiated by Seller, Buyer shall pay to Seller within ten (10) Business Days after such receipt or utilization an amount equal to such refund received or
credit utilized, together with any interest received or credited thereon, less any expenses Buyer has incurred as a result of such action. 

(h) In the event that Seller initiates a claim for refund from a third party who improperly withheld sales and use Tax, or withheld excessive
sales and use Tax, with regard to an 

  
 33 

 
Acquired Company attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date, whether the initiation of such claim begins prior to or
after the Closing, Seller shall have all rights to and interest in such refund. Buyer shall, upon request, provide Seller a limited power of attorney allowing Seller to pursue such claim for refund with and collect such refund from such third party.
If after the Closing, Buyer or an Acquired Company receives a refund of any such Tax with regard to a claim so initiated by Seller, Buyer shall pay to Seller within ten (10) Business Days after such receipt an amount equal to such refund
received, together with any interest received or credited thereon, less any expenses Buyer has incurred as a result of such action. 
 (i)
Prior to the Closing, Seller shall deliver to Buyer a written certificate, prepared and executed in accordance with the requirements of Treasury Regulation section 1.1445-2(b), certifying that Seller (or owner of Seller if Seller is a disregarded
entity for federal income tax purposes) is not a foreign person within the meaning of said Treasury Regulation. 
 (j) The Parties
acknowledge that, since (i) the Acquired Companies, other than FPLE Forney and Lamar, are classified as disregarded from their owners for federal income tax purposes, and (ii) an election pursuant to Section 338(h)(10) of the Code
shall be made with respect to the purchase and sale of the membership interests of FPLE Forney and Lamar (from a federal income tax perspective), the purchase and sale of the Interests is intended to be treated for federal income tax purposes as a
purchase and sale of the Assets and liabilities of the Acquired Companies. Buyer, Seller, and their Affiliates shall (a) cooperate in the preparation and filing of (and shall properly execute and file) elections under Section 338(h)(10) of
the Code with respect to the sale of the membership interests in each of FPLE Forney and Lamar (from a federal income tax perspective), and (b) take all such actions as are required in order to give effect to those elections for state and local
Tax purposes to the greatest extent permitted by law. Neither Buyer, the Acquired Companies, nor any of their Affiliates shall make any election under Section 338(g) of the Code with respect to the sale of the membership interests in each of
FPLE Forney and Lamar (from a federal income tax perspective). 
 Section 6.15 Appointment of Primary Representatives. In
order to facilitate the consummation of the transactions contemplated by this Agreement, each Party shall designate a primary Representative (each, a “Primary Representative”) to act as the primary point of contact to
coordinate communications and other interaction between the Parties during the Interim Period. Either Party may designate a new Primary Representative by providing written notice to the other Party. 

Section 6.16 Updating; Notification of Certain Matters. 

(a) Prior to the Closing, each Party shall promptly notify the other Party in writing of (a) the existence or occurrence, or failure to
occur, of any fact or event of which it has knowledge that would be reasonably likely to cause any representation or warranty of such Party contained in this Agreement to be untrue or inaccurate at any time from the Effective Date to the Closing
assuming such representation or warranty is made at such time, (b) the failure of such Party to comply with or satisfy in any material respect any covenant to be complied with by it hereunder, (c) any written notice or other written
communication from any Person alleging that the consent or approval of such Person is or may be required in connection with the transactions contemplated hereby, and (d) any written notice or other written communication from any Governmental
Authority in connection with the transactions contemplated hereby. 
 (b) Seller may provide to Buyer changes or additions to any of the
Schedules (a “Schedule Supplement”) solely to correct any matter that would otherwise constitute a breach or inaccuracy of any representation or warranty of Seller in Article III or Article IV such that the
closing condition in Section 7.1 cannot be satisfied. A Schedule Supplement shall only disclose facts or events 

  
 34 

 
that first occurred or arose after the Effective Date. No such Schedule Supplement shall be deemed to cure any breach or inaccuracy of any representation or warranty made in this Agreement for
purposes of Section 7.1 or otherwise alter the Parties’ rights under Section 9.1(b) unless Buyer specifically agrees thereto in writing; provided, however, that if the Closing shall occur despite the fact that Seller had
provided Buyer, as contemplated above, a Schedule Supplement such that the closing condition in Section 7.1 could not be satisfied, then notwithstanding anything to the contrary in this Agreement (including Article X) no matters
disclosed by Seller prior to the Closing in the Schedule Supplement that constituted breaches of, or inaccuracies in, one or more representations or warranties of Seller in Article III or Article IV as of the Effective Date or as of
the Closing Date shall be the basis for any indemnification by Seller pursuant to Section 10.1(a). 
 Section 6.17
Announcements. No press release or other public announcement, or public statement or comment in response to any inquiry, relating to this Agreement or the transactions contemplated hereby shall be issued or made by either Buyer or Seller, or
any of their Affiliates or Representatives, without the consent of Buyer or Seller, as the case may be, such consent not to be unreasonably withheld, conditioned or delayed; provided, however, that a press release or other public
announcement, regulatory filing, statement or comment made without such consent, including in furtherance of the requirements of Section 6.1, shall not be in violation of this Section 6.17 if it is made in order to comply
with applicable Laws or stock exchange rules and in the reasonable judgment of the Party or Affiliate making such release or announcement, based upon advice of counsel, prior review and joint approval, despite reasonable efforts to obtain the same,
would prevent dissemination of such release or announcement in a sufficiently timely fashion to comply with such applicable Laws or rules; provided, further, that in all instances Buyer or Seller, as the case may be, shall provide prompt
notice of any such release, announcement, statement or comment to the other Party. 
 Section 6.18 Further Assurances.
Subject to the terms and conditions of this Agreement, each Party shall (at its own cost and expense) at any time and from time to time, upon reasonable request, (a) do, execute, acknowledge and deliver, and cause to be done, executed,
acknowledged and delivered, all such further acts, transfers or assignments as may be required to consummate the transactions in accordance with the terms hereof and to cause to be fulfilled the closing conditions set forth in Article VII and
Article VIII and (b) take such other actions as may be reasonably required in order to carry out the intent of this Agreement; provided that in no event shall any Party be required to take any action which (i) increases in any
way the liability or obligations of such Party, (ii) in the opinion of its counsel, is unlawful or would or could constitute a violation of any applicable Law or require the approval of any Governmental Authority (other than a Buyer Approval, a
Seller Approvals or a Company Consent) or (iii) could reasonably be expected to prevent or materially impede, interfere with or delay the transactions contemplated by this Agreement. 

Section 6.19 Reserved. 

Section 6.20 Qualified Scheduling Entity. Buyer acknowledges that the Affiliate of Seller that serves as the Qualified
Scheduling Entity with respect to the Projects is not one of the Acquired Companies and upon the occurrence of the Closing such Affiliate will continue to act as the Qualified Scheduling Entity with respect to the Projects, and that Buyer and the
Acquired Companies shall be responsible for appointing and maintaining a Qualified Scheduling Entity with respect to the Projects after the Closing. 

Section 6.21 Exclusivity. 

(a) Seller agrees that during the Interim Period, Seller shall not, and shall take all action necessary to ensure that none of the Acquired
Companies or any of their respective Affiliates or 

  
 35 

 
Representatives shall, directly or indirectly, solicit, initiate or accept any other proposals or offers from any Person (A) relating to any direct acquisition or purchase of all or any
portion of the equity or ownership interest of any of the Acquired Companies or Purchased Assets other than inventory to be sold in the ordinary course of business consistent with past practice, (B) to enter into any merger, consolidation or
other business combination with any of the Acquired Companies or (C) to enter into a recapitalization, reorganization or any other extraordinary business transaction directly involving any of the Acquired Companies; or 

(b) Seller shall immediately cease and cause to be terminated all existing discussions, conversations, negotiations and other communications
with any Persons conducted heretofore with respect to any of the foregoing; provided, however, the foregoing shall not be required Seller to direct or otherwise cause any such Person to return or destroy information heretofore provided to such
Person prior to the Closing. 
 Section 6.22 Additional Assets Contribution. Prior to the Closing, Seller shall cause its
applicable Affiliates to contribute to one or more of the Acquired Companies good and valid title free and clear of all Encumbrances to each of the Additional Assets. 

Section 6.23 Forney Rotor. Promptly following the Closing, Seller will make available for purchase by Buyer, under mutually
agreeable terms and conditions, the compressor section of an upgraded combustion turbine rotor (a “Compressor Section”). If Buyer purchases a Compressor Section from Seller, Seller will use Commercially Reasonable Efforts to
procure the turbine section of an upgraded combustion turbine rotor (a “Turbine Section”) for Buyer under mutually agreeable terms and conditions, which terms and conditions the Parties agree to negotiate in good faith prior
to the Closing. If Seller is unable to procure a Turbine Section, or the Parties are unable to agree on terms and conditions for the purchase and sale of a Turbine Section, then Seller will make its Affiliate’s spare rotor available for
purchase to Buyer under mutually agreeable terms and conditions no earlier than January 1, 2017. 
 Section 6.24 Gas Supply
Agreement. Promptly following the Effective Date, Seller and Buyer shall endeavor to negotiate in good faith a mutually agreeable gas supply agreement between NextEra Energy Power Marketing, LLC and FPLE Forney, LLC and a completion payment
by Buyer or the Acquired Companies to Seller or an Affiliate of Seller with respect to the pipeline project to be constructed and owned in part by an Affiliate of Seller and connecting with the KM Facilities, with the amount of such payment and the
terms and conditions upon which it would be made to be set forth in such gas supply agreement. 
 ARTICLE VII

TERMINATION 

Section 9.1 Termination. This Agreement may be terminated, and the transactions contemplated hereby may be abandoned, as
follows: 
 (a) at any time before the Closing, (i) by Seller or Buyer, by written notice to the other, in the event that any Law or
Order restrains, enjoins or otherwise prohibits or makes illegal the sale of the Interests pursuant to this Agreement or (ii) by Buyer, by written notice to Seller, if a Governmental Authority seeks to restrain, enjoin or otherwise prohibit or
make illegal the sale of the Interests pursuant to this Agreement; 
 (b) at any time before the Closing, by Seller or Buyer, by written
notice to the other, if the other has breached its obligations or there is an inaccuracy in its representations and warranties hereunder, where the effect of such breach or inaccuracy would be to cause the conditions to the obligation to consummate
the Closing of the terminating Party not to be capable of being satisfied (assuming the Closing were otherwise to occur on the date the terminating Party delivers notice of termination), and such breach or inaccuracy (other than a breach of
Buyer’s obligation to pay the Purchase Price in accordance with the terms of Article II), if capable of being cured, has not been cured within forty-five (45) days following written notification thereof; provided, however,
that if, at the end of such forty-five (45) day period, the breaching Party is endeavoring in good faith, and proceeding diligently, to cure such breach or inaccuracy, the breaching Party shall have an additional thirty (30) days in which
to effect such cure; 
 (c) at any time before the Closing, by Buyer or Seller, by written notice to the other, on or after the date that is
two hundred seventy (270) days after the Effective Date, as the same 

  
 38 

 
may be extended pursuant to Section 6.11 (the “Initial Outside Date”); provided, that the right to terminate this Agreement under this
Section 9.1(c) shall not be available to a Party if such Party is in material breach of any of its representations, warranties, covenants or agreements under this Agreement; provided, further, that, subject to
Section 9.5, if on the Initial Outside Date, the conditions set forth in either Section 7.5 or Section 8.5 are not satisfied but all of the other conditions to Closing are satisfied (other than those conditions
that by their nature are to be satisfied at the Closing) and the conditions set forth in either Section 7.5 or Section 8.5, as the case may be, remain capable of being satisfied, then Buyer may, at its option exercisable by
delivering written notice to Seller before the Initial Outside Date, extend the Initial Outside Date until the date that is 90 days after the Initial Outside Date (such date as it may be extended (the “Outside Date”)); 

(d) at any time before the Closing, by Seller, by written notice to Buyer, if all of the conditions to close set forth in
Article VII and Article VIII have been satisfied (other than such closing conditions that by their nature are to be satisfied at the Closing which are then capable of being satisfied) or waived in writing by the applicable Party
and Buyer fails to consummate the transactions contemplated hereby at the Closing; 
 (e) by Buyer or Seller to the extent contemplated by
Section 6.11 or Section 6.12, by notice to the other Party in accordance with such Sections; or 
 (f) by mutual
written consent of Buyer and Seller. 
 Section 9.2 Effect of Termination. If this Agreement is validly terminated
pursuant to Section 9.1, except as set forth in Section 9.3 and Section 9.4, there will be no liability or obligation on the part of Seller or Buyer (or any of their respective Representatives or Affiliates),
provided that (a) Section 6.2(c), Section 6.7(b), Section 6.17, Section 9.2, Section 9.3, Section 10.4, Section 10.6, Section 10.8,
Section 11.1 and Article XII (to the extent applicable to such surviving sections) will survive any such termination and (b) each Party shall continue to be liable for any willful and intentional material breach of this
Agreement by it occurring prior to such termination. For purposes of this Section 9.2, “willful and intentional material breach” shall mean a material breach or material default that is a consequence of an act knowingly
undertaken by the breaching Party with the intent of causing a material breach of this Agreement. 
 Section 9.3 Break-up
Fee. 
 (a) If this Agreement is terminated (i) by Seller pursuant to Section 9.1(b) or Section 9.1(d)
or (ii) by Seller or Buyer if all of the conditions to Closing, other than the conditions in Section 8.6(b), have been satisfied or are capable of being satisfied on the Closing Date and this Agreement is terminated pursuant to
Section 9.1(c) or Section 9.1(f) as a result of Buyer failing to satisfy the conditions in Section 8.6(b), then, in any such case, and notwithstanding any other provision of this Agreement Buyer shall pay Seller,
by wire transfer of immediately available funds within three (3) Business Days following the date of termination, as liquidated damages, an amount of $131,303,723 (the “Break-up Fee”). 

(b) As security for Buyer’s obligations pursuant to Section 9.3(a), Section 9.4(b) or Section 9.4(c),
on the Effective Date, Buyer has provided the Break-up Fee Security in the amount equal to $131,303,723. If Buyer shall fail to pay to Seller when due the full amount of the Break-up Fee, Seller shall be entitled to draw from the Break-up Fee
Security the unpaid portion of the Break-up Fee. At the Closing, Seller shall deliver or cause to be delivered to Buyer the Break-up Fee Security for cancellation. 

  
 39 

 (c) Notwithstanding anything to the contrary in this Agreement, in the event that Buyer is
required to pay the Break-up Fee pursuant to Section 9.3(a) and Buyer pays the full Break-up Fee, payment of such fee shall be the sole and exclusive remedy of Seller and its Affiliates against Buyer and any of its former, current and
future Affiliates, representatives, shareholders, members, managers, partners, successors and assigns for any losses, damages or liabilities suffered or incurred as a result of or under this Agreement or the transactions contemplated by this
Agreement and the other Transaction Documents, including the failure of the Closing to occur, and Buyer shall have no further liability or obligation to Seller or its Affiliates relating to or arising out of this Agreement or the failure of the
transactions contemplated by this Agreement to be consummated, or in respect of any oral representation made or alleged to be have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise, and in
such event, Seller shall not bring or permit any of its Affiliates to bring any action, suit or other proceeding to seek to recover any money damages or obtain any equitable relief from Buyer or any of its Affiliates in connection therewith. 

(d) The provision for payment of liquidated damages in this Section 9.3 has been included because, in the event of the termination
of this Agreement as described in Section 9.3(a), the actual damages to be incurred by Seller can reasonably be expected to approximate the Break-up Fee and because the actual amount of such damages would be difficult if not impossible
to measure accurately. The Parties further expressly acknowledge and agree that the liquidated damages in this Section 9.3 are an integral part of the transactions contemplated by this Agreement and are intended not as a penalty, but as
full liquidated damages, in the event of Seller’s termination of this Agreement in the manner contemplated in Section 9.3(a) and as compensation for all of Seller’s losses and other expenses associated with this Agreement. In
addition, the Parties acknowledge and agree that, in the event Buyer shall fail to pay the Break-up Fee specified in this Section 9.3 when due, and Seller (or Buyer) commences a proceeding which results in a judgment or similar award
against Buyer for the Break-up Fee, then Buyer shall also pay to Seller its reasonable costs and expenses (including reasonable attorneys’ fees and expenses of enforcement) in connection with such proceeding. 

(e) For the avoidance of doubt, notwithstanding anything else in this Agreement, but subject to Section 10.8(a), in no event shall
(i) Buyer’s aggregate liability arising out of or related to this Agreement, whether relating to breach of a representation or warranty, covenant, agreement or obligation in this Agreement and whether based in tort, contract, strict
liability or other Laws or otherwise, exceed the amount of the Break-up Fee or (ii) Seller be entitled to collect both the Break-up Fee and the Regulatory Break-up Fee. 

Section 9.4 Regulatory Break-up Fee. 

(a) If (i) either Buyer or Seller terminates this Agreement pursuant to Section 9.1(a) (if, and only if, the applicable Order
giving rise to such termination arises solely in connection with the Seller Approvals from a Governmental Authority set forth as #1 on Schedule 3.3, and Buyer Approvals from a Governmental Authority set forth as #1 and #2 on Schedule
5.3 (collectively, the “Regulatory Approvals”), or (ii) either Buyer or Seller terminates this Agreement pursuant to Section 9.1(c) and, at the time of such termination, any of the conditions set forth in
Section 7.4, Section 7.5, Section 8.4 or Section 8.5 or shall have not been satisfied and such failure to be satisfied arises solely in connection with the Regulatory Approvals, and, at the time of
such termination, all other conditions to the Closing set forth in Article VII and Article VIII shall have been satisfied or waived or are capable of being satisfied, Buyer shall pay to Seller a fee of $98,477,792 (the
“Regulatory Break-up Fee”). 
 (b) Notwithstanding Section 9.4(a), in the case of the termination of
this Agreement as described in clause (i) or (ii) of Section 9.4(a), the amount of the Regulatory Break-up Fee shall be $131,303,723 if the applicable Order includes Burdensome Conditions requiring, or the

  
 40 

 
Governmental Authority shall have required Burdensome Conditions as a condition to the granting of the applicable Regulatory Approval, the taking by Buyer or its Affiliates or the Acquired
Companies of such efforts or action, individually or in the aggregate, that would not reasonably be expected to result in a Material Adverse Effect (measured on a scale relative to a company the size of the Company), without giving effect to the
exclusions set forth in clauses (g) or (h) of the definition of “Material Adverse Effect”. 
 (c) If Buyer shall fail to
pay to Seller when due the full amount of the Regulatory Break-up Fee, Seller shall be entitled to draw from the Break-up Fee Security the unpaid portion of the Regulatory Break-up Fee. 

(d) Notwithstanding anything to the contrary in this Agreement, in the event that Buyer is required to pay the Regulatory Break-up Fee
pursuant to Section 9.4(a) or Section 9.4(b) and Buyer pays the full Regulatory Break-up Fee, payment of such fee shall be the sole and exclusive remedy of Seller and its Affiliates against Buyer and any of its former,
current and future Affiliates, representatives, shareholders, members, managers, partners, successors and assigns for any losses, damages or liabilities suffered or incurred as a result of or under this Agreement or the transactions contemplated by
this Agreement and the other Transaction Documents, including the failure of the Closing to occur, and Buyer shall have no further liability or obligation to Seller or its Affiliates relating to or arising out of this Agreement or the failure of the
transactions contemplated by this Agreement to be consummated, or in respect of any oral representation made or alleged to be have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise, and in
such event, Seller shall not bring or permit any of its Affiliates to bring any action, suit or other proceeding to seek to recover any money damages or obtain any equitable relief from Buyer or any of its Affiliates in connection therewith. 

(e) The provision for payment of liquidated damages in this Section 9.4 has been included because, in the event of the termination
of this Agreement as described in Section 9.4, the actual damages to be incurred by Seller can reasonably be expected to approximate the Regulatory Break-up Fee and because the actual amount of such damages would be difficult if not
impossible to measure accurately. The Parties further expressly acknowledge and agree that the liquidated damages in this Section 9.4 are an integral part of the transactions contemplated by this Agreement and are intended not as a
penalty, but as full liquidated damages, in the event of Seller’s termination of this Agreement in the manner contemplated in Section 9.4(a) and Section 9.4(b) and as compensation for all of Seller’s losses and
other expenses associated with this Agreement. In addition, the Parties acknowledge and agree that, in the event Buyer shall fail to pay the Regulatory Break-up Fee specified in Section 9.4(a) or Section 9.4(b) when due, and
Seller (or Buyer) commences a proceeding which results in a judgment or similar award against Buyer for the Regulatory Break-up Fee, then Buyer shall also pay to Seller its reasonable costs and expenses (including reasonable attorneys’ fees and
expenses of enforcement) in connection with such proceeding. 

  
 41 

 Section 9.5 Extension of Break-up Fee Security. As a condition to Buyer’s
ability to exercise its right to extend the Initial Outside Date pursuant to Section 9.1(c), the termination date of the Break-up Fee Security must be no earlier than three months following the Outside Date.

indemnity or other payment from any third Person obligated by contract or otherwise to reimburse, indemnify or pay the Person entitled to indemnification pursuant to Section 10.1 with respect to such Losses (a “Third Party
Payment” and, together with an Insurance Payment, a “Mitigation Payment”). Notwithstanding anything to the contrary contained herein, the recovery by a Person entitled to indemnification pursuant to

duty relating to any pre-Closing actions or failures to act (including negligence or gross negligence but excluding Fraud) in connection with the Acquired Companies or any of them and the business of the Acquired Companies or any of them prior to
the Closing, provided that the foregoing shall not relieve Seller of its indemnity obligations under Section 10.1(a).

(a) The Parties agree that damages at Law shall be an inadequate remedy for the breach of any of the covenants, promises and agreements
contained in this Agreement by Buyer or Seller, and, accordingly, the Parties shall be entitled to injunctive relief with respect to any such breach, including specific performance of such covenants, promises or agreements or an order enjoining such
other party from any threatened, or from the continuation of any actual, breach of the covenants, promises or agreements contained in this Agreement, all without the necessity of proving the inadequacy of money damages as a remedy and without the
necessity of posting bond. The rights set forth in this Section 10.8(a) shall be in addition to any other rights which the Parties may have at Law or in equity pursuant to this Agreement; provided, however, that in no case
shall Seller or any of its Affiliates be entitled to both injunctive relief and the Break-up Fee or the Regulatory Break-up Fee. Except for specific performance or other injunctive or equitable relief to the extent that specific performance or such
other relief would otherwise be available to the Parties hereunder, Buyer and Seller acknowledge and agree that, from and after Closing, the indemnification provisions in this Article X, Section 6.2(c), Section 6.2(d),
Section 6.5(b), Section 6.6, Section 6.14(b), Section 6.14(c) and Section 2.6 shall be the exclusive remedy of Buyer and Seller with respect to the transactions contemplated by this
Agreement, except for Fraud.

 (b) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, NO PARTY OR ITS AFFILIATES, OR
THEIR RESPECTIVE REPRESENTATIVES SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES OR LOSS OF REVENUE, INCOME OR PROFITS, DIMINUTION OF VALUE OR LOSS OF BUSINESS REPUTATION OR OPPORTUNITY OF ANY OTHER
PARTY OR ANY OF SUCH PARTY’S AFFILIATES, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM THE OTHER PARTY’S OR ITS AFFILIATE’S, OR ANY OF THEIR RESPECTIVE OFFICER’S,
DIRECTOR’S, EMPLOYEE’S OR REPRESENTATIVE’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT, AND IN PARTICULAR, NO “MULTIPLE OF PROFITS” OR “MULTIPLE OF CASH FLOW” OR SIMILAR VALUATION
METHODOLOGY SHALL BE USED IN CALCULATING THE AMOUNT OF ANY LOSSES, PROVIDED THE FOREGOING SHALL NOT APPLY TO THIRD-PARTY CLAIMS FOR WHICH ANY PARTY IS OBLIGATED TO INDEMNIFY ANOTHER PARTY HEREUNDER (“Non-Reimbursable
Damages”). 
 (c) Notwithstanding anything in this Agreement to the contrary, no Representative or Affiliate of Seller (other
than NEER pursuant to the Seller Parent Guaranty) shall have any personal liability (whether in equity or at law, in contract, in tort or otherwise) to Buyer or any other Person as a result of the breach of any representation, warranty, covenant,
agreement or obligation of Seller in this Agreement, and no Representative or Affiliate of Buyer (other than Buyer Parent Guarantor pursuant to the Buyer Parent Guaranty) shall have any personal liability (whether in equity or at law, in contract,
in tort or otherwise) to Seller or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of Buyer in this Agreement. 

Section 10.9 Indemnification Procedures. 

(a) In the event that (i) a Party seeking indemnification (the “Indemnified Party”) becomes aware of the existence
of any claim in respect of which payment may be sought under this Article X (an “Indemnification Claim”), or (ii) any legal proceedings shall be instituted, or any claim shall be asserted, by any Person not party
to this Agreement in respect of an Indemnification Claim (a “Third Party Claim”), the Indemnified Party shall promptly cause written notice thereof (a “Claim Notice”) to be delivered to the party from
whom indemnification is sought (the “Indemnifying Party”); provided that, so long as such notice is given within the applicable time period described in Section 10.2(a)(i) or Section 10.2(a)(ii), no
delay on the part of the Indemnified Party in giving any such notice shall relieve the Indemnifying Party of any indemnification obligation hereunder unless (and then solely to the extent that) the Indemnifying Party is materially prejudiced by such
delay. Each Claim Notice shall be in writing and (A) shall specify the basis for indemnification claimed by the Indemnified Party, (B) if such Claim Notice is being given with respect to a Third Party Claim, shall describe in reasonable
detail such Third Party Claim and shall be accompanied by copies of all relevant pleadings, demands and other papers served on the Indemnified Party, and (C) shall specify the amount of (or if not finally determined, a good faith estimate of)
the Losses being incurred by, or imposed upon, the Indemnified Party on account of the basis for the claim for indemnification. 
 (b) The
Indemnifying Party shall have the right, at its sole option and expense, to be represented by counsel of its choice and to defend against, negotiate, settle or otherwise handle any Indemnification Claim and if the Indemnifying Party elects to defend
against, negotiate, settle or otherwise handle any Indemnification Claim, it shall within fifteen (15) days after receipt of notice of 

  
 47 

 
the underlying Third Party Claim (or sooner, if the nature of the Indemnification Claim so requires) (the “Dispute Period”) notify the Indemnified Party of its intent to
do so, provided that the Indemnifying Party shall not be entitled to assume control of such defense (unless otherwise agreed to in writing by the Indemnified Party) and shall pay the reasonable fees and expenses of counsel retained by the
Indemnified Party if (i) the claim for indemnification relates to or arises in connection with any criminal or quasi criminal action or proceeding or (ii) the claim seeks an injunction or equitable relief against the Indemnified Party (any
Indemnification Claim the defense of which is assumable by an Indemnifying Party hereunder, an “Assumable Claim”). If the Indemnifying Party does not elect within the Dispute Period to defend against, negotiate, settle or
otherwise handle any Assumable Claim, the Indemnified Party may defend against, negotiate, settle or otherwise handle such Assumable Claim. If the Indemnifying Party elects to defend against, negotiate, settle with or otherwise handle any Assumable
Claim, the Indemnified Party may participate, at its own expense, in the defense of such Assumable Claim; provided, however, that such Indemnified Party shall be entitled to participate in any such defense with separate counsel at the
reasonable expense of the Indemnifying Party if (i) so requested by the Indemnifying Party to participate, or (ii) in the reasonable opinion of counsel to the Indemnified Party, a conflict exists between the Indemnified Party and the
Indemnifying Party; and provided, further, that the Indemnifying Party shall not be required to pay for more than one such counsel for all Indemnified Parties in connection with any Assumable Claim. Seller, on the one hand, and Buyer, on the
other hand, agree to cooperate with each other in connection with the defense, negotiation or settlement of any such Assumable Claim. Notwithstanding anything in this Section 10.9 to the contrary, the Indemnifying Party shall not,
without the written consent of the applicable Indemnified Party, settle or compromise any Assumable Claim or permit a default or consent to entry of any judgment (each a “Settlement”) unless (A) the claimant and such
Indemnifying Party provide to such Indemnified Party an unqualified release from all liability in respect of the Assumable Claim, (B) such Settlement does not impose any liabilities or obligations on the Indemnified Party, and (C) with
respect to any non-monetary provision of such Settlement, such provisions would not, in the Indemnified Party’s reasonable judgment, have or be reasonably expected to have any material adverse effect on the business, Assets, condition
(financial or otherwise), results of operations or prospects of the Indemnified Party. 
 (c) After any final decision, judgment or award
shall have been rendered by a Governmental Authority of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a Settlement or arbitration shall have been consummated, or the Indemnified Party and the Indemnifying
Party shall have arrived at a mutually binding agreement with respect to an Indemnification Claim hereunder, the Indemnified Party shall forward to the Indemnifying Party notice of any sums due and owing by the Indemnifying Party pursuant to this
Agreement with respect to such matter and the Indemnifying Party shall make prompt payment thereof pursuant to the terms of the agreement reached with respect to the Indemnification Claim. 

(d) If the Indemnifying Party does not undertake within the Dispute Period to defend against an Assumable Claim, then the Indemnifying Party
shall have the right to participate in any such defense at its sole cost and expense, but, in such case, the Indemnified Party shall control the investigation and defense. Notwithstanding the foregoing or anything in this Section 10.9(d)
to the contrary, the Indemnified Party shall not effect a Settlement without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. 

(e) In the event that an Indemnified Party has delivered a Claim Notice in respect of an Indemnification Claim that does not involve a Third
Party Claim, the Indemnifying Party and the Indemnified Party shall attempt in good faith to resolve any disputes with respect to such Claim Notice within forty-five (45) days of the delivery by the Indemnifying Party thereof, and if not
resolved in such forty-five (45) day period, such Indemnification Claim may be resolved through judicial actions, suits or proceedings brought by either such party or by such other means as such parties mutually agree.

 Section 10.10 Access to Information. After the Closing Date, Seller and Buyer
shall grant each other (or their respective designees), and Buyer shall cause the Acquired Companies to grant to Seller (or its designees), access at all reasonable times upon reasonable notice to all of the information, books and records relating
to the Acquired Companies in its possession, and shall afford such party the right (at such party’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to implement the provisions of, or to
investigate or defend any claims between the Parties arising under, this Agreement other than (a) information relating to post-Closing periods that is commercially sensitive, trade secret or otherwise confidential or (b) in the case of

Non-Acquired Company Affiliate that is commercially sensitive, trade secret or otherwise confidential or (ii) in the case of claims between the Parties, any information that is subject to any attorney client, work product or other privilege or

indirectly to Buyer by or on behalf of Seller in confidence by it and shall not disclose or cause to be disclosed by Buyer or any third party without Seller’s prior express written consent (such consent not to be unreasonably withheld,
conditioned or delayed); provided, however, that Buyer may disclose Seller Confidential Information to persons who provide financial analysis, financial ratings, banking, legal, accounting, or other services to Buyer in connection with
Buyer’s evaluation or implementation of the transactions contemplated by this Agreement; provided, further, that such persons have been informed of the duties required hereby.

Confidential Information if it has become generally known or available within the industry or the public though no act or omission of Seller. 

(b) From and after the Closing, Seller shall maintain any Buyer Confidential Information which has been or will be disclosed directly or
indirectly to Seller by or on behalf of Buyer in confidence by it and shall not disclose or cause to be disclosed by Seller or any third party without Buyer’s prior express written consent (such consent not to be unreasonably withheld,
conditioned or delayed); provided, however, that Seller may disclose Buyer Confidential Information to persons who provide financial analysis, financial ratings, banking, legal, accounting, or other services to Seller in connection with the
implementation of the transactions contemplated by this Agreement; provided, further, that such persons have been informed of the duties required hereby. 

(c) Notwithstanding anything to the contrary in this Agreement, the provisions of this Section 11.3 shall not prohibit the
disclosure of Buyer Confidential Information by Seller to the extent reasonably required (i) to prepare or complete any required Tax returns or financial statements, (ii) in connection with audits or other proceedings by or on behalf of a
Governmental Authority, (iii) to comply with applicable Law, (iv) to provide services to Buyer or its Affiliates, pursuant to this Agreement or any of the other Transaction Documents, or (v) to assert any rights or remedies or perform
any obligations under this Agreement or any of the other Transaction Documents. 
 Section 11.4 Limitations on Confidential
Information. 
 (a) Notwithstanding Section 11.2(b) and Section 11.3(b), from and after the Closing, Seller
Confidential Information and Buyer Confidential Information may be disclosed if required by any Governmental Authority or court or otherwise by Law; provided, however, that: (i) such Seller Confidential Information and Buyer Confidential
Information is submitted under any and all applicable provisions for confidential treatment and (ii) if the disclosing Party is permitted to do so, the other Party is given written notice of the requirement for disclosure promptly after such
disclosure is requested, so that it may take whatever action it deems appropriate, including intervention in any proceeding and seeking a protective order or an injunction, to prohibit such disclosure. If Seller Confidential Information or Buyer
Confidential Information is disclosed under the provisions of this Section 11.4(a), the disclosing Party shall notify the other Party of the same in writing not later than five (5) Business Days following the disclosure. 

(b) Each Party hereby agrees that from and after the Closing it will not make any use of any Seller Confidential Information or Buyer
Confidential Information, as applicable, received pursuant to this Agreement, except in connection with the transactions contemplated by this Agreement and the other Transaction Documents, unless specifically authorized to do so in writing by the
other Party, and this Agreement shall not be construed as a license or authorization to either Party to utilize Seller Confidential Information or Buyer Confidential Information, as applicable, except for such purpose. 

  
 50 

 (c) From and after the Closing, upon a Party’s request, the other Party shall return or
destroy as promptly as practicable, but in a period not to exceed ten (10) Business Days, (i) all Seller Confidential Information or Buyer Confidential Information (as applicable) provided to such Party, as appropriate, including all
copies of such Seller Confidential Information, or Buyer Confidential Information (as applicable) and (ii) all notes or other documents in digital or other format in their possession or in the possession of other persons to whom Seller
Confidential Information or Buyer Confidential Information (as applicable) was properly provided by such Party. Non-destruction of electronic copies of materials or summaries containing or reflecting Seller Confidential Information or Buyer
Confidential Information (as applicable) that are automatically generated through data backup or archiving systems and which are not readily accessible by a Party’s business personnel shall not be deemed to violate this Agreement, so long as
Seller Confidential Information or Buyer Confidential Information (as applicable) contained in or reflected in such electronic backup records is not disclosed or used in violation of the other terms of this Agreement. 

(d) The obligations of the parties under Section 11.2(b) and Section 11.3(c) shall not apply to the tax treatment or

of the of the transactions contemplated by this Agreement and all other materials of any kind (including opinions or other tax analysis) that are provided to a Party relating to such tax treatment and tax structure (all such information that may be
disclosed being the “Tax Information”). The preceding sentences are intended to cause the transactions contemplated by this Agreement not to be treated as having been offered under conditions of confidentiality for purposes
of Sections 1.6011-4(b)(3) and 301.6111-2(a)(2)(ii) (or any successor provision) of the Treasury Regulations issued under the Code and shall be construed in a manner consistent with such purpose. For purposes of this provision, the Tax Information
includes only those facts that may be relevant to understanding the purported or claimed United States federal income tax treatment or tax structure of the transactions contemplated by this Agreement and, to eliminate any doubt, therefore
specifically does not include information that either reveals or standing alone or in the aggregate with other information so disclosed tends of itself to reveal or allow the recipient of the information to ascertain the identity of Seller or Buyer,
or any third parties involved in any of the transactions contemplated by this Agreement or the other Transaction Documents.

admission, indication or evidence that such item or other matter is material, that such item is reasonably likely to result in a Material Adverse Effect or that such item or other matter is required to be referred to or disclosed in the Schedules.

No disclosure in the Schedules relating to any possible breach or violation of any agreement, Law or regulation shall be construed as an admission or indication that any such breach or violation exists or has actually occurred. The headings and

or relied upon by any other Person or for any other purpose. 
 Section 12.5 Waiver. Any term or condition of this
Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. No
waiver by any Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion.

hereunder may be assigned or delegated by any Party without the prior written consent of the other Party, except that Buyer may (without the consent of Seller) collaterally assign this Agreement or any of its rights, interests or obligations
hereunder to any Person providing financing to Buyer or its Affiliates, but no such collateral assignment shall release Buyer of its obligations under this Agreement. Subject to this Section 12.8, this Agreement is binding upon, inures

 53 

 Section 12.9 Headings. The headings used in this Agreement have been inserted
for convenience of reference only and do not define or limit the provisions hereof. 
 Section 12.10 Invalid Provisions.
If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future Law, and if the rights or obligations of any Party under this Agreement will not be materially and adversely affected thereby, such
provision will be fully severable, this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, the remaining provisions of this Agreement will remain in full force and
effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom and in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal,
valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible. 

Section 12.11 Counterparts; Facsimile. This Agreement may be executed in any number of counterparts, each of which will be

 Notes: 
  

	(a)	Represents excess cash available to fund future operating needs or required principal and interest payments. Such excess cash is typically swept to parent and replaced with a cash management guarantee. There will be no
amounts outstanding under the cash management guarantee at closing, as any amounts previously drawn on the guarantee shall be returned in cash prior to closing. For the avoidance of doubt, any such cash management guarantee or other guarantee shall
not be deemed “cash and cash equivalents” for any such accounts and the applicable amounts in such accounts shall only be deemed “cash and cash equivalents” for the calculation of “Current Assets” if deposited in cash
prior to the closing. 

	(b)	Represents cash available in the Bank of America operating account (net of any outstanding checks) to cover next month’s estimated O&M cash disbursements. This account is funded on a monthly basis from cash
available in the Project Revenues Collection Account. 

	(c)	Represents cash that may be transferred to the Project Revenues Collection Account at any time. 

	(d)	Represents estimated cash required to fund the next 12 months of Major Maintenance Expenditures, as defined in the Credit Agreement. This account is replenished on a quarterly basis, and any cash not required to pay for
next month’s major maintenance expenditures is typically swept to parent and replaced with a major maintenance reserve guarantee. There will be no amounts outstanding under the major maintenance reserve guarantee at closing, as any amounts
previously drawn on the guarantee shall be returned in cash prior to closing. 

	(e)	Represents cash required to cover the next two estimated quarterly minimum principal and interest payments as of each Debt Service and Reserve Funding Date, as defined in the Credit Agreement. This amount is adjusted on
a quarterly basis with funds transferred to or from the Project Revenues Collection Account and is in the form of a debt service reserve guarantee. There will be no amounts outstanding under the debt service reserve guarantee at closing, as the Debt
Service Reserve Account will be funded with cash prior to closing. 

	(f)	Primarily represents estimated receivables for monthly settlements due from hedge counterparty and daily energy settlements due from ERCOT that will be collected in the following month. 

	(g)	Primarily consists of amounts due from NextEra Energy Power Marketing, LLC (“NEPM”) for monthly energy sales based on the day-ahead index pricing. Such sales and receivables are not forecasted, but any actual
amounts will be assumed to be collected upon closing and excluded from working capital (removed from Buyer’s opening trial balance). 

	(h)	Consists of all spare parts included on Exhibit K. 

	(i)	Property and casualty insurance premiums are paid by parent and allocated down to the various benefitted entities, including La Frontera. These insurance policies are non-transferable, so any related prepaid amounts do
not benefit the Buyer and have been excluded from working capital (removed from Buyer’s opening trial balance). 

  
 C-3 

	(j)	Consists of prepaid administrative and rating agency fees paid annually in connection with the financing. 

	(k)	Derivative and income tax assets and liabilities are excluded from working capital (removed from Buyer’s opening trial balance). 

	(l)	This amount is intended to cover all third party trade payables, including accrued expenses for any invoices received on or after the closing date for costs incurred prior to the closing date (excluding other current
liabilities specifically identified herein). 

	(m)	Primarily consists of amounts due to 1) NEPM for estimated fuel purchases for the current month and 2) other related parties for estimated payroll and other operating costs for the current month, including accrued
payroll taxes and incentives for 2015. Amount is assumed to be paid to related parties upon closing and excluded from working capital (removed from Buyer’s opening trial balance). 

	(n)	Consists of the estimated property tax assessments for the 2015 calendar year that are paid in arrears (tax bills due in January 2016). 

	(o)	Consists of estimated 2015 audit fees in connection with financing requirement. Parent will pay all such audit fees directly on behalf of La Frontera, so this amount has been excluded from working capital (removed from
Buyer’s opening trial balance). 

	(p)	Consists of interest on the outstanding principal balance of the debt for 1 day (12/31/15) that is not included in the minimum principal and interest payment scheduled to be made on 12/31/15. Daily interest in the
same amount will continue to be accrued after 12/31/15 until closing on or before 3/31/16. 

	(q)	All outstanding principal balances associated with long-term debt obligations are excluded from working capital. 

	(r)	Consists of Adjustments to balance sheet to provide a normalized amount of working capital based on LTM average amounts plus growth based on financial projections provided. For the avoidance of doubt the $34,000,000
normalization Adjustment to Net Working Capital in Table I is included Aggregate Target Net Working Capital Amount only, and will not be added to Proposed Aggregate Net Working Capital Amount or the Final Aggregate Net Working Capital Amount.
