Securities of the Company designated as the “1.78% Notes Due 2011” (the “Notes”), initially issued in an aggregate principal amount of ¥50,000,000,000 on May 26, 2006. Such series of Securities has been established
pursuant to, and is one of an indefinite number of series of debt securities of the Company, issued or issuable under and pursuant to, the Indenture, dated as of July 19, 2005 (the “Indenture”), duly executed and delivered by the
Company, as Issuer, and J.P. Morgan Trust Company, National Association, as Trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Notes and of the terms upon which this Note is, and is to be, authenticated and delivered. The terms, conditions and provisions of the Notes are those
stated in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, and those set forth in this Note. To the extent that the terms, conditions and other provisions of this Note modify, supplement or
are inconsistent with those of the Indenture, then the terms, conditions and other provisions of this Note shall govern. 
 All capitalized
terms which are used but not defined in this Note shall have the meanings assigned to them in the Indenture. 
 The Company may, without the
consent of the Holders, create and issue additional Securities ranking equally with the Notes and otherwise identical in all respects (except for their date of issue, issue price and the date from which interest payments thereon shall accrue) so
that such additional Securities shall be consolidated and form a single series with the Notes; provided, however, that no additional Securities of any existing or new series may be issued under the Indenture if an Event of Default has
occurred and remains uncured thereunder. 
 2. Ranking. The Notes shall constitute the senior unsecured debt obligations of the
Company and shall rank equally in right of payment among themselves and with all other existing and future senior unsecured debt obligations of the Company. 
 3. Payment of Overdue Amounts. The Company shall pay interest, calculated on the basis of the actual number of days in the period and a year of 365 days, on overdue principal and overdue installments of
interest, if any, from time to time, on demand at the interest rate borne by the Notes to the extent lawful. 
 4. Payment of Additional
Amounts; Redemption Upon a Tax Event. 
 (a) Payment of Additional Amounts. The Company shall pay to the holder (including, for
purposes of this Section 4, each beneficial owner) of this Note who is a Non-U.S. Person (as defined below) additional amounts as may be necessary so that every net payment of principal of and interest on this Note to such holder, after
deduction or withholding for or on account of any present or future tax, assessment or other governmental charge imposed upon such holder by the United States or any taxing authority thereof or therein, will not be less than 

 2 
  

 
the amount provided in this Note to be then due and payable (such amounts, the “Additional Amounts”); provided, however, that the Company
shall not be required to make any payment of Additional Amounts for or on account of: 
 (i) any tax, assessment or other governmental charge
that would not have been imposed but for (A) the existence of any present or former connection between such holder, or between a fiduciary, settlor, beneficiary of, member or shareholder of, or possessor of a power over, such holder, if such
holder is an estate, trust, partnership or corporation, and the United States including, without limitation, such holder, or such fiduciary, settlor, beneficiary, member, shareholder or possessor, being or having been a citizen or resident of the
United States or treated as a resident thereof or being or having been engaged in trade or business or present in the United States, or (B) the presentation of this Note for payment on a date more than 30 days after the later of (x) the
date on which such payment becomes due and payable and (y) the date on which payment thereof is duly provided for; 
 (ii) any estate,
inheritance, gift, sales, transfer, excise, personal property or similar tax, assessment or other governmental charge; 
 (iii) any tax,
assessment or other governmental charge imposed on foreign personal holding company income or by reason of such holder’s past or present status as a passive foreign investment company, a controlled foreign corporation, a personal holding
company or foreign personal holding company with respect to the United States, or as a corporation that accumulates earnings to avoid United States federal income tax; 
 (iv) any tax, assessment or other governmental charge which is payable otherwise than by withholding from payment of principal of or interest on this Note; 
 (v) any tax, assessment or other governmental charge required to be withheld by any paying agent from any payment of principal of or interest on this Note
if such payment can be made without withholding by any other paying agent; 
 (vi) any tax, assessment or other governmental charge which
would not have been imposed but for the failure to comply with certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connections with the United States of the holder, if such
compliance is required by statute or by regulation of the U.S. Treasury Department as a precondition to relief or exemption from such tax, assessment or other governmental charge; 
 (vii) any tax, assessment or other governmental charge imposed on interest received by (A) a 10% shareholder (as defined in Section 871(h)(3)(B)
of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and the regulations that may be promulgated thereunder) of the Company or (B) a controlled foreign corporation with respect to the Company within the meaning of the
Code; 
 (viii) any withholding or deduction that is imposed on a payment to an individual and is required to be made pursuant to that
European Union Directive relating to the taxation of savings adopted on June 3, 2003 by the European Union’s Economic and Financial 

 3 
  

 
Affairs Council, or any law implementing or complying with, or introduced in order to conform to, such Directive; or 
 (ix) any combination of items (i), (ii), (iii), (iv), (v), (vi), (vii) and (viii) in this Section 4(a); 
 nor shall any Additional Amounts be paid to any holder who is a fiduciary or partnership to the extent that a beneficiary or settlor with respect to such fiduciary, or a
member of such partnership or a beneficial owner thereof, would not have been entitled to the payment of such Additional Amounts had such beneficiary, settlor, member or beneficial owner been the holder. 
 The term “Non-U.S. Person” means any corporation, partnership, individual or fiduciary that is, as to the United States, a foreign corporation,
a non-resident alien individual who has not made a valid election to be treated as a United States resident, a non-resident fiduciary of a foreign estate or trust, or a foreign partnership one or more of the members of which is, as to the United
States, a foreign corporation, a non-resident alien individual or a non-resident fiduciary of a foreign estate or trust. 
 (b) Redemption
Upon a Tax Event. The Notes may be redeemed at the option of the Company in whole, but not in part, on a date (such date, the “Tax Redemption Date”) to be fixed by the Company on not more than 60 days’ and not less than 30
days’ notice, at a redemption price equal to 100% of the principal amount of the Notes (the “Redemption Price”) plus accrued but unpaid interest, if any, and any Additional Amounts thereon, if the Company determines that as a result

 (vii) the ISIN and Common Code numbers of the Notes. 
 The notice of redemption regarding the Notes shall be, at the election of the Company, given by the Company or, at the Company’s request, by the
Trustee in the name and at the expense of the Company. 
 On or before the opening of business on any Tax Redemption Date, the Company shall
deposit with the Trustee or with the Paying Agent (or, if the Company is acting as its own paying agent, segregate and hold in trust as provided in Section 5.03 of the Indenture) an amount of money sufficient to pay the Redemption Price of, and
except if the Tax Redemption Date shall be an Interest Payment Date, accrued but unpaid interest on, the Notes to be redeemed on the Tax Redemption Date. 
 The notice of redemption having been given as specified above, the Notes shall, on the Tax Redemption Date, become due and payable at the Redemption Price, and from and after such date, unless the Company shall
default in the payment of the Redemption Price and accrued but unpaid interest, if any, the Notes shall cease to bear interest. Upon surrender of the Notes for redemption in accordance with such notice, the Notes shall be paid by the Company at the
Redemption Price, together with accrued but unpaid interest, if any, to the Tax Redemption Date. 
 If the Notes, having been called for
redemption, shall not be so paid upon surrender thereof for redemption, the Redemption Price shall, until paid, bear interest from the Tax Redemption Date at the interest rate borne by this Note. 
 5. Place and Method of Payment. The Company shall pay principal (and Redemption Price, if any) of and interest on the Notes at the office or
agency of the U.S. Paying Agent in the Borough of Manhattan, The City of New York and of the London Paying Agent in London and, for so long as the Notes are listed on the Irish Stock Exchange, of the Irish Paying Agent in Dublin, Ireland;

 5 
  

 
may pay interest by check mailed to the person entitled thereto at such person’s address as it appears on the Registry for the Notes.

modification of the Indenture and the Notes without the consent of the Holders in certain circumstances and requiring the consent of Holders of not less than a majority in aggregate principal amount of the Notes and Securities of other series that
would be affected in certain other circumstances. However, the Indenture requires the consent of each Holder of the Notes and Securities of other series that would be affected for certain specified amendments or modifications of the Indenture and
the Notes. These provisions of the Indenture, which provide for, among other things, the execution of supplemental indentures, are applicable to the Notes.

manner, with the effect and subject to the conditions provided in the Indenture. The Indenture provides that, in the event of such an acceleration of the maturity of the Notes, the Holders of a majority in aggregate principal amount of all of the
Notes of this series then Outstanding, voting as a separate class, in accordance with the provisions of, and in the circumstances provided by, the Indenture, may rescind and annul such acceleration and its consequences with respect to all of the
Notes.

 11. Form and Denominations; Global Note; Definitive Notes. The Notes are being issued in registered form without interest coupons in denominations
of ¥10,000,000 and integral multiples of ¥1,000,000 in excess thereof. The Notes are being issued in the form of a single global note (the “Global Note”), evidencing all or any portion of the Notes and registered in the name of
Chase Nominees Limited, as nominee of the Common Depositary (including its respective successors) under the Indenture. The Notes shall be issued in certificated form (each, a “Definitive Note”) only in the following limited circumstances:
(1) the Common Depositary is at any time unwilling or unable to continue as the Common Depositary, or Clearstream Banking, société anonyme or Euroclear Bank S.A./N.V. ceases to be a clearing agency registered under
applicable law, and a successor Common Depositary is not appointed by the Company or a successor clearing agency satisfactory to the Company is not established within 90 days after the

Company receives notice thereof; (2) the Company delivers to the Trustee a Company Order to the effect that this Note shall be exchangeable for
Definitive Notes; or (3) an Event of Default has occurred and is continuing with respect to the Notes, in each such case this Note shall be exchangeable for Definitive Notes in an equal aggregate principal amount. Such Definitive Notes shall be
registered in such name or names as the Common Depositary shall instruct the Trustee. 
 12. Registration, Transfer and Exchange. As
provided in the Indenture and subject to certain limitations therein set forth, the Company shall provide for the registration of the Notes and the transfer and exchange of the Notes, whether in global or definitive form. At the option of the
Holders, at the offices of the U.S. Transfer Agent, the London Transfer Agent or, so long as the Notes are listed on the Irish Stock Exchange, the Irish Transfer Agent (each as defined in Section 14 hereof), or at any of such other offices or
agencies as may be designated and maintained by the Company for such purpose pursuant to the provisions of the Indenture, and in the manner and subject to the limitations provided in the Indenture, but without the payment of any service charge,
except for any transfer tax or other governmental charges imposed in connection therewith subject to Section 4 hereof, the Notes may be transferred or exchanged for an equal aggregate principal amount of the Notes of like tenor and of other
authorized denominations upon surrender and cancellation of the Notes upon any such transfer. 
 The Company, the Trustee and any agent of
the Company or of the Trustee may deem and treat the holder as the absolute owner of this Note (whether or not the Notes shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payments
hereon, or on account hereof, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or of the Trustee shall be affected by any notice to the contrary. All such payments made to or upon the order of such
holder shall, to the extent of the amount or amounts paid, effectually satisfy and discharge liability for moneys payable on this Note. 
 Notwithstanding the preceding paragraphs of this Section 12, any registration of transfer or exchange of a Global Note shall be subject to the terms of the legend appearing on the initial page thereof. 
 13. No Recourse Against Others. No recourse under or upon any obligation, covenant or agreement of the Company arising under or set forth in the
Notes or under the Indenture, or for any claim based thereon or otherwise in respect thereof, shall be had against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any successor corporation,

Facility Intellectual Property, (iii) restrict the Business in order to accommodate a third Person’s intellectual property rights, or (iv) permit any third party to use any Facility Intellectual Property. To Sellers’ Knowledge,

Closing: 
 4.1.1 Required Consents; Other Covenants. 
 (a) Each Party shall provide reasonable cooperation to the other Party in obtaining consents, approvals or actions of, making all filings

Act. 
 (ii) As promptly as practicable and, in any event, within thirty (30) days of the Effective Date, the Purchaser
and Rockingham shall jointly file, with Purchaser having primary responsibility therefor, with the NCUC all documents reasonably required to obtain the NCUC Approvals, and the Purchaser and the Sellers shall use their commercially reasonable efforts
to cause the NCUC Approvals to be issued as soon as practicable after the Effective Date. The Parties shall consult on and coordinate all principal filings submitted by Purchaser and Rockingham to the NCUC in connection with the NCUC Approvals.

 (iii) As promptly as practicable and, in any event, within sixty (60) days of the Effective Date, the Purchaser and

 29 

 
filings intended to be submitted by Purchaser and Rockingham to Governmental Authorities in connection therewith. 
 (v) Regarding Environmental Permits, as promptly as practicable and, in any event, within sixty (60) days of the Effective Date,
Sellers and Purchaser shall file, or jointly file, such applications and other documents reasonably required to obtain approval of the transfer of all Facility Permits (other than the Title V Air Emission Permit) or to obtain any Required
Governmental Consents effective as of Closing or as soon as possible thereafter. Notwithstanding the foregoing, in no event shall Sellers have any obligation to expend any funds to assure the transfer or re-issuance of any Facility Permit. The
Parties shall reasonably consult on and coordinate all filings intended to be submitted by Purchaser and Rockingham to Governmental Authorities in connection therewith. 
 The Parties shall furnish to each other’s counsel such necessary information and assistance as the other party may request in connection with its preparation of any such filing or submission that is necessary to
obtain the foregoing consents, approvals or actions. The Parties shall consult with each other as to the appropriate time of making such filings and submissions and shall make such filings and submissions at the agreed upon time. The Parties shall

 (b) Purchaser, at its sole cost and
expense, shall use commercially reasonable efforts to obtain, as promptly as practicable but in any event within forty-five (45) days after the Effective Date, from a title company of Purchaser’s choice, and that is reasonably acceptable
to Sellers (Sellers hereby confirm Chicago Title Insurance Company as an acceptable title company), a commitment for title insurance covering the Real Property (the “Title Insurance Commitment”) and a survey (the
“Survey”) of the Real Property (or update of an existing survey) prepared by a licensed professional surveyor selected by Purchaser, and who is reasonably acceptable to Sellers (Sellers hereby confirm C.E. Robertson as an acceptable
surveyor). Rockingham shall provide Purchaser and its employees and agents access to the Real Property upon reasonable advance notice to conduct the Survey. In the event (i) any exceptions appear in the Title Insurance Commitment (other than
Permitted Liens and the standard pre-printed exceptions, which standard exceptions Sellers shall cause to be deleted at Closing by appropriate title company affidavits and customary indemnities) or the Title Insurance Commitment reflects any
requirements or conditions that must be satisfied for the deletion of all standard and general exceptions (other than the customary seller affidavits and indemnities which Sellers shall deliver at Closing) and for issuance of the Title Policy with
the following endorsements to the Title Policy to be issued pursuant to the Title Insurance Commitment: comprehensive, contiguity (with respect to Tract #1, Tract #2, Tract #3 and Tract #4 as described on Schedule 3.1.10(a), Purchaser acknowledging
that Tract #5 described thereon is not contiguous with the others) zoning, same as survey, separate tax parcel, access, subdivision and easement (collectively, “Objectionable Title  

  

 30 

 
Matters”), or (ii) the Survey shows any easements, rights-of-way, encroachments, or other matters affecting the Site (other than Permitted
Liens) (“Objectionable Survey Matters”), Purchaser shall notify Sellers in writing of such fact within thirty (30) days of the later of the receipt of the Title Insurance Commitment or the Survey, which notice must be
accompanied by a copy of the Title Insurance Commitment, the Survey and descriptions of any Objectionable Title Matters and Objectionable Survey Matters. If Purchaser fails to give Sellers timely notice of any Objectionable Title Matters or
Objectionable Survey Matters, then the matters revealed by the Title Commitment and/or the Survey, as the case may be, and not timely identified by Purchaser as Objectionable Title Matters or Objectionable Survey Matters, shall be deemed to be
additional “Permitted Liens.” If Purchaser has given Sellers timely notice of any Objectionable Title Matters or Objectionable Survey Matters, then Sellers shall have the right, but not the obligation, to cure such Objectionable Title
Matters or Objectionable Survey Matters. If Sellers have not (I) cured such Objectionable Title Matters or Objectionable Survey Matters within thirty (30) days after Seller’s receipt of Purchaser’s notice thereof (the
“Curative Period”) or confirmed in writing to Purchaser that such Objectionable Title Matters will be cured by Sellers on or before Closing, or notified Purchaser of Sellers’ election not to cure the same, then within fifteen
(15) Business Days following the end of such thirty (30) day period or, if earlier, the date that Sellers notify Purchaser of their election to cure or not to cure, Purchaser shall deliver to Sellers its notice to the effect that it has
completed such examination of Seller’s title to the Real Property as it deems appropriate under the circumstances, and that based on such examination Purchaser has either (1) found that title to the Real Property is acceptable and that
Purchaser desires to proceed with the Closing without reduction in Purchase Price (in which event the uncured Objectionable Title Matters and Objectionable Survey Matters shall become and be Permitted Liens; provided, however, that in
no event shall Liens securing indebtedness of Sellers or Sellers’ Affiliates become Permitted Liens and Sellers shall pay and cause such Liens to be released) and that Purchaser agrees to accept the issuance of a title policy at closing that is
subject to exceptions for the Permitted Liens and, if applicable, without the deletion of any general or standard exceptions that are attributable to any uncured Objectionable Title Matter or Objectionable Survey Matter and without issuance of any
of the above listed endorsements thereto to the extent such endorsements may not be issued as a result of any uncured Objectionable Title Matter or uncured Objectionable Survey Matter, or (2) found that title to the Real Property is not
acceptable and that because of such nonacceptable title Purchaser has elected to terminate this Agreement, whereupon this Agreement shall terminate and the Real Property and other Purchased Assets shall cease to be subject to this Agreement. If
Purchaser fails to give notice of its election, Purchaser shall be deemed to have elected to proceed to Closing as described in clause (1) above, notwithstanding such Objectionable Title Matters or Objectionable Survey Matters, and
notwithstanding that the title policy to be issued at Closing pursuant to the Title Insurance Commitment may be subject to general or standard exceptions that would be deleted but for such uncured Objectionable Title Matter or Objectionable Survey
Matter and may be issued without one or more of the above listed endorsements as a result of an uncured Objectionable Title Matter or uncured Objectionable Survey Matter . 
  

 31 

 (c) Purchaser shall, at Purchaser’s sole cost and expense, engage a nationally or
regionally recognized independent environmental consultant to perform, on or before sixty (60) days after the Effective Date, a Phase I Environmental Assessment with respect to the Real Property. The consultant shall be selected by Purchaser
subject to Sellers’ approval which shall not be unreasonably withheld. In addition, with Sellers’ prior written approval, Purchaser shall engage such consultant to perform any other assessment that Purchaser reasonably deems necessary to
determine compliance with or risks arising under Environmental Law with respect to a condition identified in such Phase I Environmental Assessment, including assessments that require sampling of any media at the Real Property (“Phase 2
Work”). If Sellers withhold their written approval for any such Phase 2 Work as described in the preceding sentence, Purchaser shall have the option of terminating this Agreement by giving written notice to Sellers. If Sellers give their
written approval for such Phase 2 Work, Rockingham shall provide Purchaser and its employees and agents reasonable access to the Real Property after receipt of reasonable advance written notice of Purchaser’s intent to conduct such Phase 2
Work; provided, however, Purchaser shall not unreasonably interfere with the conduct of Seller’s Business. Purchaser shall allow Sellers’ representatives (at Sellers’ option) to be present at any physical inspection of the Real
Property in connection with such Phase I Environmental Assessment and Phase 2 Work, and to discuss with such consultant or Purchaser’s employees at any time (during reasonable business hours) such assessment or Phase 2 Work, and to review all
written materials, including drafts of any written reports, as Purchaser shall from time to time request. At Sellers’ request, any final report prepared by an environmental consultant shall be certified to both Sellers and Purchaser. Upon
completion of the Phase I Environmental Assessment and the Phase 2 Work (as the case may be), Purchaser shall provide to Sellers’ copies of all draft and final reports prepared in connection therewith and promptly inform Sellers of any
determination that it makes, based on such assessments that the condition to Closing set forth in Section 5.1.11 has not been met. If such condition to Closing has not been met, Purchaser shall have the option of terminating this
Agreement by so stating in such notice, whereupon this Agreement shall automatically terminate and the Real Property and other Purchased Assets shall not be subject to this Agreement. Purchaser shall advise Sellers if any matters disclosed by such
Phase I Environmental Assessment or Phase 2 Work would, in its reasonable judgment, render the representations and warranties set forth in Section 3.1.13 or Section 3.1.15 false or misleading in any respect. If Purchaser does
not exercise its option to terminate this Agreement as provided in this subsection, any such matters so disclosed to Sellers shall be deemed to be included in all relevant sections of the Sellers’ Disclosure Schedule and shall be deemed to be
Identified Environmental Liabilities. 
 (d) The provisions of this Section 4.1.1(d) set forth the obligations of
the Parties with respect to the Capacity Contracts. Notwithstanding any other provision in this Agreement, the Capacity Contracts shall not be included in the Assumed Agreements except to the extent contemplated by, and in accordance with, the
provisions of this Section 4.1.1(d). For purposes of this Section 4.1.1(d), the obligations of Sellers include the obligations of Dynegy to cause Dynegy Power Marketing to take the actions described. For clarification, any
references to assignment of the Capacity Contracts to Purchaser or assumption of any obligations under or with respect to the Capacity 

  

 32 

 
Contracts refer only to those specific agreements for sale and delivery of power included in the definition of the term “Capacity Contracts,” and
do not include the master agreements related to such transactions or any schedules, annexes or exhibits to such master agreement. 
 (i) As promptly as practicable after the Effective Date: 
 (A) the Purchaser, Rockingham and Dynegy Power Marketing
shall jointly file, with Purchaser having primary responsibility therefor, with the FERC all documents reasonably required to obtain the FERC Capacity Contract Assignment Approval; and 
 (B) Sellers shall use their commercially reasonable efforts to obtain consents from the counterparties to the Capacity Contracts to
(1) the assignment of the Capacity Contracts to Purchaser, and the assumption by Purchaser of Dynegy Power Marketing’s obligations thereunder from and after the Closing, (2) the release of Dynegy Power Marketing and any Affiliate of
Dynegy from any Liability under such Capacity Contracts incurred after the Closing, and (3) the return, at or within a reasonable time after the Closing, of all collateral (including any letter of credit) posted by Dynegy Power Marketing or any
Affiliate of Dynegy with respect to any such Capacity Contract. Purchaser shall cooperate with Sellers, to the extent reasonably requested by Sellers, in discussions with the counterparties to the Capacity Contracts and shall, in connection with
such discussions, negotiate in good faith to enter into master agreements with such counterparties (or modification of Purchaser’s existing master agreements, if applicable) to govern the terms and conditions under which the Capacity Contracts
would be governed if assigned to and assumed by Purchaser. 
 (C) If (1) a FERC Capacity Contract Assignment Approval is
received and such approval shall not have (I) imposed or required any material adverse condition or restriction on Purchaser, Sellers, Dynegy Power Marketing, the Facility or the Business and (II) been reversed, stayed, enjoined, set aside,
annulled or suspended; and (2) consent has been obtained from the counterparty to such Capacity Contract as described in subsection (B) above, then such Capacity Contract shall be deemed an Assumed Agreement hereunder and, at Closing,
Purchaser shall, and Sellers shall cause Dynegy Power Marketing to, enter into an Assignment Agreement with respect to such Capacity Contract in a form reasonably acceptable to the Parties. 
 (ii) With respect to any Capacity Contract that is not assigned to and assumed by Purchaser in accordance with subsection (i) above,
Seller and Purchaser shall negotiate in good faith (but in no event shall they be required to so negotiate for more than 30 days) regarding an alternative arrangement among the Parties with respect to such Capacity Contracts, which may include
effecting a 

  

 33 

 
termination of such Capacity Contract, entering into one or more “back-to-back” agreements whereby Purchaser agrees to provide power to Dynegy
Power Marketing to the extent and at the times required under such Capacity Contract, or some other arrangement, if any, upon which the Parties may mutually agree in their discretion. 
 (iii) If Purchaser and Sellers do not effect a mutually acceptable alternative arrangement as provided in subsection (ii) above,
Sellers may give written notice to Purchaser that they shall terminate this Agreement effective upon the earlier of Purchaser’s written acceptance of such termination and the end of the 60-day negotiation period described in the succeeding
sentence. Notwithstanding Sellers’ notice of termination as provided in the immediately preceding sentence, Purchaser shall have a period of 60 days after delivery of Sellers’ termination notice in which Purchaser may negotiate directly
with the counterparties to any such Capacity Contract, with respect to the terms and conditions of an arrangement, acceptable to Purchaser and at Purchaser’s cost, under which Dynegy Power Marketing and any Affiliate of Dynegy would be released
from all Liabilities under such Capacity Contract from and after the Closing and under which any collateral posted by any of them would be returned at or within a reasonable time after the Closing. If Purchaser reaches agreement with respect to such
an arrangement, it shall give notice to Sellers of the same within such 60-day period, and Sellers’ notice of termination shall automatically become null and void and have no effect. 
 (iv) With respect to any Capacity Contract, an “Acceptable Disposition” of such Capacity Contract shall mean any of the
following: (A) such Capacity Contract shall have been deemed an Assumed Agreement and an assignment agreement with respect thereto executed and delivered in accordance with subsection (i) above; (B) Sellers and Purchaser shall have
reached a mutually acceptable alternative arrangement as described in subsection (ii) above, or (C) Dynegy Power Marketing and any and all Affiliates of Dynegy have been released from all Liabilities under such Capacity Contract and any
collateral posted with respect to such Capacity Contract shall have been or will be returned in accordance with subsection (iii) above. The Parties agree that the achievement of an Acceptable Disposition for all Capacity Contracts shall be a
condition to Sellers’ obligations hereunder as provided in Section 5.2. hereof. 
 (e) Purchaser’s
rights to enter the Real Property to conduct the survey, inspection and environmental assessment described in this Section 4.1.1, and any other entry of the Real Property by Purchaser contemplated by this Agreement, shall be subject to
the following terms and conditions: 
 (i) All work Purchaser wishes to perform on the Real Property, including all
inspections and tests, and work associated therewith, shall be fully identified in writing to Sellers prior to the commencement of any such work, and all such work shall be performed during normal business hours and in accordance and compliance with
Sellers’ customary security and safety procedures. 
  

 34 

 (ii) If Sellers so elect, Sellers’ designated representative shall accompany any
such surveyor, engineer or others during any such inspections and assessments. As part of the consideration for Sellers’ consent to allow Purchaser to enter the Real Property, Purchaser shall deliver to Sellers a copy of all surveys and written
reports obtained by Purchaser as a result of Purchaser’s exercise of its rights under this Agreement relating to the Real Property, or as a result of any work relating to the Real Property. 
 (iii) Purchaser shall obtain and pay for all permits and approvals required by any Governmental Authority with jurisdiction over any work
performed by or on behalf of Purchaser on the Real Property. 
 (iv) Purchaser shall be solely responsible and liable for
payment of all costs and expenses associated with the work performed in connection with the exercise of its rights of entry and Purchaser shall promptly pay all such costs and expenses. Purchaser shall not permit any Lien to be placed against any
portion of the Real Property as a result of Purchaser’s exercise of its rights of entry or performance of work on the Real Property. Within five (5) Business Days after Purchaser’s receipt of any notice to Purchaser that a Lien has
been placed or claimed against any portion of the Real Property as a result of Purchaser’s exercise of its rights under this Agreement or the performance of any work in connection therewith, Purchaser shall pay, bond or otherwise discharge the
Lien and remove it as an encumbrance or cloud on Rockingham’s title to the Real Property. If Purchaser fails so to pay, bond or discharge the Lien, Sellers shall have the right, but not the obligation, to pay, bond or otherwise discharge the
Lien and all costs incurred by Seller in so doing, including, without limitation, Sellers’ reasonable and actual attorneys’ fees and costs, shall be reimbursed to Seller by Purchaser within five (5) Business Days of Purchaser’s
receipt of written demand for same from Sellers. 
 (v) Purchaser shall save harmless, indemnify and defend Sellers from any
and all claims, losses, penalties, demands, judgments, damages, injuries, or expenses, (including attorneys’ and paralegals’ fees and costs), for bodily injury or property damage that Sellers incur as a result of the entry upon the Real
Property by Purchaser or Purchaser’s employees, agents, contractors or representatives or as a result of any of the work performed by or for Purchaser, but not including any such claims arising from an Environmental Condition identified by
Purchaser or from Sellers’ gross negligence or willful misconduct. Purchaser’s indemnification obligations contained in this section shall survive any assignment, cancellation or termination of this Agreement. 
 (vi) Purchaser warrants that, upon completion of the work or termination of this Agreement, whichever occurs first, Purchaser shall
repair any damage caused by Purchaser and/or its agents, contractors, and employees on or to the Real Property and Purchaser shall restore the Real Property to its pre-existing condition. Purchaser shall be solely liable and responsible for all
costs and expenses associated with such repair and restoration. If Purchaser’s activities 

  

 35 

 
on the Real Property create a violation of any Laws, including, but not limited to, any Environmental Law, then Purchaser shall either (i) take all
necessary and appropriate action to restore the Real Property to its former condition at Purchaser’s sole cost and expense; or (ii) if Purchaser fails so to promptly restore the Real Property to its pre-existing condition following
Purchaser’s receipt of notice of the need therefor, then Purchaser shall pay all costs and expenses incurred by Sellers or their agents for all remediation and restoration required as a result of any such changed condition. Notwithstanding the
foregoing, except for the repair and restoration obligations of Purchaser expressly set forth in this Section 4.1.1(e)(vi), Purchaser shall have no Liability or obligation under this Section 4.1.1(e) with respect to any
Environmental Condition it identifies on the Real Property. Purchaser shall reimburse Seller for all such obligations, costs and expenses within ten (10) days of Seller’s demand therefor. All such sums not paid when due shall incur
interest at the Default Rate. 
 (vii) Upon any termination of this Agreement other than termination by reason of
Sellers’ default or breach, Purchaser shall promptly deliver to Sellers copies of all reports, surveys, studies, and other materials obtained by Purchaser as a result of its entry upon the Real Property, together with satisfactions or waivers
of lien for all person or entities supplying labor, materials or professional services to Purchaser relating to Purchaser’s entry upon the Real Property. 
 (viii) Purchaser’s obligations under this Section 4.1.1(e) shall survive Closing or termination of this Agreement.

 (f) At the request of a Party, (i) the other Party shall use commercially reasonable efforts to effectuate, to the
extent not effectuated on or before Closing, the assignment by Sellers of the Assumed Agreements, the assumption by Purchaser of the Assumed Liabilities, and the release of Sellers and their Affiliates from Liability under the Assumed Agreements for
the period after Closing; and (ii) the Parties shall use their commercially reasonable efforts to obtain Required Consents not obtained on or before Closing. 
 4.1.2 Fulfillment of Conditions. 
 (a) Each Party shall use commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or advisable under Law to consummate and make effective
the purchase, sale, assignment, conveyance, transfer and delivery of the Purchased Assets and the assumption of the Assumed Liabilities pursuant to this Agreement. Such actions shall include each Party’s using its commercially reasonable
efforts to ensure satisfaction of the conditions precedent to its obligations hereunder. 
 (b) Each Party shall give notice
to the other promptly after becoming aware of (i) the occurrence or non-occurrence of any event whose occurrence or non-occurrence would be likely to cause any representation or warranty contained in this 

  

 36 

 
Agreement to be untrue or inaccurate in any material respect at any time from the Effective Date to the Closing Date and (ii) any failure of a Party to
comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder. 
 Section 4.2
Preservation of Purchased Assets. 
 (a) Except as otherwise provided in this Section 4.2, after
the Effective Date and prior to Closing, Sellers shall (i) preserve and maintain the Purchased Assets in accordance with Good Operating Practices and (ii) purchase and maintain insurance insuring against physical loss or damage to the
Purchased Assets consistent with Sellers’ prior practice. 
 (b) Except as set forth on Schedule 4.2, after the
Effective Date and prior to Closing, the Sellers shall not, without the written consent of Purchaser: (i) dispose of or assign (other than in the ordinary course of the Business consistent with Sellers’ past practice), or incur or permit
to exist any Lien (other than a Permitted Lien) on, any of the Purchased Assets; (ii) enter into, amend, modify, terminate, grant any waiver of any term under or give any consent with respect to any Easement, any Permitted Lien, any Assumed
Agreement, or any new contract or any Permit related to the Facility; (iii) permit to lapse any rights to any Facility Intellectual Property; (iv) amend the Rockingham certificate of formation or operating agreement in any way that would
have an adverse effect on the transactions contemplated by this Agreement; (v) issue any new limited liability company interests in Rockingham or grant any options or other rights to acquire such interests, including any securities convertible
into such interests; (vi) take any action that adversely alters the FERC or NCUC regulatory status of Rockingham, the Site or the Facility; (vii) except in the ordinary course of the Business and consistent with Sellers’ past
practice, enter into or amend any employment, severance, change in control, retention, consulting, termination or other compensation-related agreement or arrangement with or with respect to the Employees; or (viii) enter into any agreement to
do or engage in any of the foregoing within the scope permitted by this Section 4.2(b); provided, however, that with respect to clause (ii) above, (A) Purchaser’s consent shall be deemed to have been given to
Sellers in the event Purchaser shall not have responded within ten (10) Business Days of Seller’s written request for such consent (which consent shall be provided by Sellers to the addresses shown on Schedule 4.2(b)), and
(B) the consent of Purchaser shall not be required in connection with any amendment, modification, termination, or waiver of, consent to, or obtaining of, any Permit related to the Facility (1) in emergency situations in which Sellers must
take action to prevent injury to Persons or physical loss or damage to the Purchased Assets or (2) as required to comply with applicable Law. Any new contracts entered into by Sellers within the scope permitted by this
Section 4.2(b) shall be deemed to be Assumed Agreements for purposes of this Agreement. 
 (c) The Sellers shall
ensure that the inventory of Consumables on the Closing Date is not materially less than the inventory of Consumables maintained by Sellers consistent with Sellers’ past practices. 
  

 37 

 (d) The Sellers shall not use or remove any fuel oil at or from the Facility, except
(i) to the extent requested by a counterparty to a Capacity Contract in compliance with the terms of such Capacity Contract; or (ii) in the ordinary course of the Business consistent with Sellers’ past practice, and Sellers shall
replace or replenish such fuel oil in the ordinary course of the Business consistent with Sellers’ past practice. 
 (e)
Sellers shall use commercially reasonable efforts to effectuate, on or before Closing, the conveyance of that portion of the Real Property that is described as “Tract #5” on Schedule 3.1.10(a) pursuant to the proposed Donation
Agreement described in Schedule 3.1.10(f). Sellers shall notify Purchaser if such conveyance is completed on or before Closing, in which case, such conveyed property shall be deemed to be an Excluded Asset and the description of the Real
Property set forth on Schedule 3.1.10(a) shall be deemed amended to delete said Tract #5. 
 (f) Sellers shall use
commercially reasonable efforts to obtain the written consent of Siemens Westinghouse to permit Sellers to disclose and make available to Purchaser all Siemens Westinghouse technical advisories received by Sellers or their Affiliates with respect to
the Facility. If such consent is obtained, Sellers agree to disclose such technical advisories to Purchaser and shall advise Purchaser of any action taken by Sellers in response thereto. 
 Section 4.3 Purchaser’s Inspection Right. After the Effective Date and prior to Closing, Purchaser and its Related Persons shall have
access subject to the terms and conditions of Section 4.1.1(d) hereof and upon reasonable prior written notice, to the Site and the Facility and, if requested, to the Facility Books and Records, all for purposes of inspection and review.
During any inspection or review, Purchaser shall comply, and shall cause its Related Persons to comply, with all of the applicable safety and security procedures applicable to the Site and to conduct any inspection or review in a manner causing
minimum interference with the Sellers’ activities. 
 Section 4.4 Equipment Warranties. In connection with the conveyance
of the Purchased Assets at Closing, Sellers shall transfer to Purchaser, without recourse, any non-expired Equipment Warranties relating to the Purchased Assets not expressly contained in the Assumed Agreements, together with any non-expired
warranties under any agreement related to the purchase of any Materials and Equipment. In the event any Equipment Warranties are granted pursuant to agreements relating to the Purchased Assets as well as assets of either Seller not included in the
Purchased Assets, to the extent the same are freely transferable and not expired, Seller shall transfer such warranties to the extent they apply to the relevant Purchased Assets. 
 Section 4.5 Risk of Loss. Prior to the Closing, all risk of loss, damage or other casualty to the Purchased Assets shall be borne by
Sellers, and Sellers shall promptly notify Purchaser of any such loss, damage or casualty or any other change in condition of the Purchased Assets. Prior to the Closing, Sellers shall repair to the previous condition of the Purchased Assets any
damage, loss or casualty to the Purchased Assets or breakage of any component of the Purchased Assets that occurs; provided, however, that if the amount of such damage, loss or breakage would reasonably be expected to exceed
$10,000,000, and the Parties are unable to 

  

 38 

 
reach an agreement on a remedy for such damage, loss or breakage within thirty (30) days of the occurrence of such loss, damage or breakage, either
Party shall be entitled to terminate this Agreement upon notice to the other Party; and provided further, however, that during the period prior to such agreement on a remedy, Sellers shall not be obligated to remedy such loss but shall take
commercially reasonable steps to prevent any additional loss. 
 Section 4.6 Employee Matters. 
 (a) Purchaser agrees to provide written offers of employment to all Employees at least 30 days prior to the Employee Transition Date
(defined below) and to hire the Employees who wish to accept such offers of employment (the “Hired Employees”). The offers shall provide employees at least 5 days to accept or reject such offers in writing. The effective date of
such employment shall be effective at 12:00 a.m. on the day immediately following the day of Closing (the “Employee Transition Date”). Notwithstanding the foregoing, Purchaser shall not be required to employ any Employee who does
not satisfy Purchaser’s general policies for employment relating to drug testing, physical examination (for craft positions) and criminal record. 
 (b) Purchaser shall provide to Sellers copies of any written offers of employment made to the Employees. Within seven (7) days preceding the Employee Transition Date, Purchaser shall notify Seller in writing of
the Employees who have accepted offers of employment with Purchaser. 
 (c) Notwithstanding anything in this Agreement to the
contrary, the Parties acknowledge that certain Hired Employees may not actively report to work on the first Employee Transition Date immediately following the day of Closing. Within 30 days following the day of Closing, Purchaser will provide
Sellers with a list (the “Absentee List”) of such Hired Employees who did not actively report to work for the Purchaser on the Employee Transition Date. With respect to any Hired Employees who are not scheduled to report to work on
the first Business Day following the day of Closing because of (i) an absence under the applicable personal paid time or similar policy, or (ii) a work schedule that did not identify such day as a work day for such Hired Employee, the
first day such Hired Employee is scheduled to return to work shall be used for preparation of the Absentee List instead of the Employee Transition Date. The Absentee List shall be prepared by Purchaser in accordance with their then current practice
for recording time or otherwise accounting for employee attendance. Purchaser shall provide such reasonable documentation to Sellers as Sellers may reasonably request to validate the correctness of the Absentee List. 
 (d) Purchaser agrees to employ the Hired Employees on terms that are in the aggregate, during the initial 12 months of employment from the
Employee Transition Date (a) generally as favorable as such Employees’ current employment terms with respect to salary, benefits, bonuses, base hours and vacation and (b) no less favorable than those afforded to similarly situated
employees of Purchaser and its Affiliates (with credit for any prior payments toward benefit deductibles based upon satisfactory documentation provided by the employee). Purchaser will pay employees at a rate of pay that is comparable to other
similarly situated employees at their place of 

  

 39 

 
employment. To the extent that this results in a pay reduction based upon the base salary in effect as of the Closing Date, the employee will be offered a
signing bonus that is equal to lost base wages for a twelve month time frame based upon a forty hour work week. 
 The Parties
agree that, with respect to all Hired Employees identified on the final Absentee List, as approved by Sellers, (i) Purchaser will notify Sellers as soon as reasonably practicable following the day on which each such Hired Employee actively
reports to work for Purchaser (the “First Reported Day”) and (ii) Purchaser will be solely responsible for and pay each such Hired Employee, from and after the Closing Date through the First Reported Day, such leave of absence
payments as such Hired Employee was receiving immediately prior to the Closing Date and provide such Hired Employee with benefits as provided under Section 4.6(f), including but not limited to, medical benefits; provided, however, that
if the First Reported Day for any Hired Employee does not occur within sixty (60) days following the Closing Date, Purchaser agrees to notify Sellers of this fact and each of Purchaser and Sellers agree to cooperate as reasonably appropriate if
it becomes necessary for such Hired Employee to apply for long-term disability under the applicable Dynegy Benefit Plan (defined below) as a result of a pre-Closing claim giving rise to liability for long-term disability benefits under Dynegy
Benefit Plans as provided in Section 4.6(h); and provided, further, that if such Hired Employee applies for and is determined to be eligible for long-term disability benefits under the applicable Dynegy Benefit Plans, then as of the date
of determination of such long-term disability (the “LTD Determination Date”), Purchaser and Sellers agree to take such action as is necessary for Sellers to provide long-term disability, medical, dental and other applicable benefits
to such Hired Employee from and after the LTD Determination Date, for as long as Sellers provide such benefits under the applicable Sellers’ Benefit Plans to similarly situated employees.] 
 (e) Effective immediately preceding the Employee Transition Date and except as otherwise provided herein, the Hired Employees’
employment with Sellers or Sellers’ Affiliate shall terminate and the Hired Employees shall no longer participate in Sellers’ or their Affiliates’ employee benefit plans, programs, practices and arrangements, whether written or oral
(the “Dynegy Benefit Plans”), except as provided in such Dynegy Benefit Plans for similarly situated employee plan participants. 
 (f) Effective immediately upon the Employee Transition Date and except as otherwise provided herein, the Hired Employees’ employment with the Purchaser shall commence and the Hired Employees shall be eligible to
participate in the Purchaser’s employee benefit plans, programs, practices and arrangements under the terms of each such plan, program, practice and arrangement consistent with the requirements of Section 4.6(d) and
Section 4.6(i). 
 (g) Notwithstanding anything herein to the contrary, Purchasers shall provide severance
benefits no less favorable to the Hired Employees than those maintained by the Sellers and their Affiliates until at least the first (1st) anniversary of the Employee Transition Date. However, this provision shall not apply to any Hired
Employee who voluntarily resigns or who is terminated by the Buyer for poor 

  

 40 

 
performance or misconduct. With respect to Employees who do not become Hired Employees, Purchaser shall reimburse Seller for the costs of any severance
benefits provided to such Employees under the terms of the Dynegy Inc. Severance Pay Plan. 
 (h) Purchaser shall not assume
any of the Dynegy Benefit Plans and shall have no obligations and shall have no liabilities with respect to the Dynegy Benefit Plans. Claims for workers’ compensation or long-term disability benefits arising out of occurrences prior to the
Employee Transition Date shall be the responsibility of Sellers. Claims for workers’ compensation or Long-Term Disability benefits for Hired Employees arising out of occurrences on or subsequent to the Employee Transition Date shall be the
responsibility of Purchaser. Nothing herein shall be deemed or construed to (i) give rise to any rights, claims, benefits, or causes of action to any Employee, (ii) constitute an amendment of any Purchaser’s employee benefit plans, or
(iii) prevent, restrict, or limit Purchaser or Sellers or Sellers’ Affiliates following the Employee Transition Date from modifying or terminating its pension or other benefit plans, programs or policies from time to time as it may deem
appropriate. 
 (i) Hired Employees shall be credited with the same number of years of service as they are credited by Dynegy,
or an Affiliate of Dynegy, for severance, eligibility, vesting purposes, access to retiree medical (to the extent Purchaser has such a plan) and benefit accrual except (i) for benefit accrual under a defined benefit pension plan or
(ii) to the extent such credit would result in a duplication of benefits. Hired Employees shall (if permitted by the Purchaser’s plan) be permitted to roll-over any 401(k) account balances and associated loans (if permitted by the
Purchaser’s plan) they may have as of the Employee Transition Date into plans sponsored by Purchaser. Purchaser and Sellers shall cooperate in good faith to permit the transition of Hired Employees from flexible spending accounts maintained by
Sellers and their affiliates to similar accounts maintained by Purchasers and their affiliates in a manner that is fair to the Hired Employees. 
 (j) Sellers shall be responsible for compliance with and liability under Section 4980B of the Code and Sections 601 through 608 of Title I of the Employee Retirement Income Security Act of 1974, as amended
(“COBRA”) with respect to any COBRA-qualifying events that occur on or prior to the Closing to the extent mandated by COBRA with respect to the Employees, Sellers’ or Sellers’ Affiliates former employees, and the spouses
and dependents of both of the foregoing. Purchaser shall be responsible for compliance with and liability under COBRA with respect to any COBRA-qualifying events that occur after the Closing with respect to Hired Employees, and with respect to the
spouses and dependents of such Employees. 
 (k) Notwithstanding anything in this Agreement to the contrary, Purchaser shall
be solely responsible for and shall pay all bonuses and incentive payments applicable to the Hired Employees who remain employed by the Purchaser or its Affiliates through the earlier of March 1, 2007, or the date on which Purchaser otherwise
pays its annual bonuses and incentive payments to similarly situated employees (the “2006 Bonus Payment Date”). Such bonuses and incentive payments shall be paid to applicable Hired Employees on the 2006 Bonus Payment Date in
accordance with the 

  

 41 

 
bonus and incentive plans or programs of Purchaser, but in no event in an amount less than the target amount that would have been earned by such Hired
Employees under Sellers’ bonus and incentive plans and programs (which are listed on Schedule 3.1.16 – “Employees”) for 2006 regardless of whether all applicable targets under such Sellers’ bonus and incentive
plans and programs had been satisfied. 
 Section 4.7 Emission Allowances. Notwithstanding anything to the contrary herein,
Purchaser and Sellers shall use commercially reasonable efforts, including executing any required forms and providing appropriate notices to Governmental Authorities, in a timely fashion, to ensure that Purchaser will obtain any legally available
rights to those Emission Allowances described in Schedule 2.1.1 attached hereto that are to be transferred to it pursuant to Section 2.1.1; provided, however, in no event shall Sellers have any obligation to expend
any funds to assure the transfer of such Emission Allowances. Furthermore, Purchaser covenants that Purchaser shall not sell or transfer any Emission Allowances transferred to Purchaser pursuant to this Agreement until such time as Purchaser has
satisfied applicable Governmental Authorities that sufficient Emissions Allowances exist in the Facility account to satisfy all Emissions Allowance obligations of the Facility for the year in which the Closing occurs at the time when due.

 Section 4.8 Notification. 
 4.8.1 Company and Sellers. Prior to the Closing, each Seller shall promptly notify Purchaser in writing if it becomes aware of any
fact or condition that (i) causes or constitutes a breach of any representation or warranty set forth in Section 3.1 or (ii) would have caused or constituted a breach of any such representation or warranty had such
representation or warranty been made as of the time of occurrence or discovery of such fact or condition. Should any such fact or condition require any change in Sellers’ Disclosure Schedule, Sellers shall promptly deliver to Purchaser a
supplement to Sellers’ Disclosure Schedule specifying such change. During the same period, each Seller shall promptly notify Purchaser of the occurrence of any breach of any covenant of Sellers or of the occurrence of any event that would
reasonably be expected to make the satisfaction of the conditions set forth in ARTICLE V impossible or unlikely. 
 4.8.2 Purchaser. Prior to the Closing, Purchaser shall promptly notify Sellers in writing if Purchaser becomes aware of any fact or condition that (i) causes or constitutes a breach of any representation or warranty set forth in
Section 3.2 or (ii) would have caused or constituted a breach of any such representation or warranty had such representation or warranty been made as of the time of occurrence or discovery of such fact or condition. Should any such
fact or condition require any change in Purchaser’s Disclosure Schedule, Purchaser shall promptly deliver to Sellers a supplement to the Purchaser’s Disclosure Schedule specifying such change. During the same period, Purchaser shall
promptly notify Sellers of the occurrence of any breach of any covenant of Purchaser or of the occurrence of any event that would reasonably be expected to make the satisfaction of the conditions in ARTICLE V impossible or unlikely.

 4.8.3 Effect of Supplemental Disclosure. Any notice delivered by a Party pursuant to this Section 4.8 or
in a certificate delivered pursuant to Section 2.4.1(a)(viii) or Section 2.4.1(b)(xv) shall be disregarded for purposes of determining an inaccuracy or breach of 

  

 42 

 
a representation or warranty made by such Party in this Agreement or in Sellers’ Disclosure Schedule or Purchaser’s Disclosure Schedule, as the
case may be; provided, however, that if such supplemental disclosure causes a condition to the obligation of the other Party under ARTICLE V not to be satisfied, and the Party making such supplemental disclosure (at the time of
making such disclosure) expressly identifies such condition that will not be satisfied in the notice delivered pursuant to this Section 4.8 or in a certificate delivered pursuant to Section 2.4.1(a)(viii) or
Section 2.4.1(b)(xv), then in the event the Party receiving such supplemental disclosure nevertheless proceeds to close notwithstanding the failure of such condition to be satisfied, then such supplemental disclosure shall be given
effect as if disclosed on the date of this Agreement. Notwithstanding the foregoing, any supplemental disclosure of information of which (i) either Seller had actual knowledge on the Effective Date, (ii) which either Seller knew was a
breach of a representation or warranty in Section 3.1 as of the Effective Date and (iii) that such Seller intentionally failed to disclose on the Effective Date shall be disregarded for all purposes under this Agreement.

Purchaser’s right or ability to own and operate the Facility or conduct the Business or otherwise impose on Purchaser any adverse condition, restriction or burden that imposes a material cost on Purchaser’s ownership or operation of the
Facility or conduct of the Business, materiality to be determined in the context of the transactions contemplated by this Agreement taken as a whole.

 TERMINATION 
 Section 6.1
Termination Prior to Closing. This Agreement may be terminated, and the transactions contemplated hereby may be abandoned: 
 (a) at any time before the Closing, by Sellers or Purchaser upon notice to the other Party, in the event that any Law becomes effective restraining, enjoining, or otherwise prohibiting or making illegal the
consummation of the transactions contemplated by this Agreement; 
 (b) at any time before the Closing as provided in
Sections 4.1.1(b), (c) and (d), and Section 4.5; 
 (c) at any time before the Closing,
by Sellers or Purchaser upon notice to the other Party, in the event (i) of a breach hereof by the non-terminating Party that would reasonably be expected to give rise to a Material Adverse Effect, if the non-terminating Party fails to cure
such breach within thirty (30) days following notification thereof by the terminating Party; or (ii) any condition to such Party’s obligations under this Agreement (other than the payment of money to the other Party) becomes
impossible or impracticable to satisfy with the use of commercially reasonable efforts, or best efforts where applicable, so long as such impossibility or impracticability is not caused by a breach hereof by such Party; provided further,
however, that if it is reasonably possible that the circumstances giving rise to the impossibility or impracticability may be removed prior to the expiration of the time period provided in this Section 6.1(c), then such notification
may not be given until such time as the removal of such circumstances is no longer reasonably possible or practicable within such time period; or 
 (d) at any time following March 31, 2007, by Sellers or Purchaser upon notice to the other Party if the Closing shall not have occurred on or before such 

  

 46 

 
date and such failure to consummate is not caused by a breach of this Agreement by the terminating Party. 
 Section 6.2 Effect of Termination or Breach Prior to Closing. If this Agreement is validly terminated pursuant to Section 6.1,
there shall be no liability or obligation on the part of Sellers or Purchaser (or any of their respective Related Persons), except that the provisions of ARTICLE X, ARTICLE XI and Sections 12.1, 12.2, 12.3, 12.4,
12.5, 12.6, 12.7, 12.9, 12.10, 12.11, 12.12, 12.13, 12.14 and 12.15, Section 4.1.1(e) and this Section 6.2 shall continue to apply following any such
termination. Notwithstanding any other provision in this Agreement to the contrary, if this Agreement is validly terminated by Purchaser or Sellers pursuant to Section 6.1(c) as a result of the willful breach by the other Party, the
terminating Party may exercise such remedies as may be available at law or in equity. 
 ARTICLE VII 
 INDEMNIFICATION 
 Section 7.1
Indemnification by Sellers. Subject to the limitations set forth in Section 6.2, Section 7.4, ARTICLE IX and Section 11.1, after Closing Sellers jointly and severally agree to indemnify, defend
and hold Purchaser and its Related Persons (each, a “Purchaser Indemnified Party”) harmless from and against (and to reimburse each Purchaser Indemnified Party as the same are incurred for) any and all Losses incurred by any
Purchaser Indemnified Party resulting from any of the following: 
 (a) any inaccuracy or breach of a representation or
warranty made by Sellers in this Agreement, any Transaction Agreement and any other agreement delivered pursuant to this Agreement, or in any certificate delivered pursuant to this Agreement; 
 (b) the breach by Sellers of, or default in the performance by Sellers of, any covenant, agreement or obligation to be performed by
Sellers pursuant to this Agreement or any of the other Transaction Agreements; and 
 (c) the Excluded Liabilities, other than
the Pre-Closing Environmental Liabilities and/or Identified Environmental Liabilities. 
 Notwithstanding anything in this Agreement to the
contrary, for purposes of determining Losses for which Sellers shall be obligated to indemnify any Purchaser Indemnified Party pursuant to this Section 7.1, with respect to each representation and warranty made by Sellers in ARTICLE
III of this Agreement that is subject to a materiality qualification (including any qualification referring to a Material Adverse Effect), whether an “inaccuracy” or “breach” of such representation or warranty shall be deemed
to have occurred, and the amount of Losses arising therefrom (including, without limitation, for purposes of aggregating Losses to determine when the minimum amount as described in Section 7.4.2 has been exceeded) shall be determined
without taking such materiality qualification into account. 
 Section 7.2 Indemnification by Purchaser. Subject to the
limitations set forth in Section 6.2, Section 7.4, ARTICLE IX and Section 11.1, after Closing Purchaser hereby agrees to indemnify, defend and hold Sellers and their Related Persons (each, a “Seller
Indemnified Party”), harmless from and against (and to reimburse each Seller Indemnified Party as the same 

  

 47 

 
are incurred for) any and all Losses incurred by any Seller Indemnified Party resulting from any of the following: 
 (a) any inaccuracy or breach of a representation or warranty made by Purchaser in this Agreement, Purchaser’s Disclosure Schedule or
in any certificate delivered pursuant to this Agreement; 
 (b) the breach by Purchaser of, or default in the performance by
Purchaser of, any covenant, agreement or obligation to be performed by Purchaser pursuant to this Agreement or any of the other Transaction Agreements; 
 (c) the Assumed Liabilities; 
 (d) all Liabilities arising out of the ownership, possession,
use, maintenance or operation of the Purchased Assets or Purchaser’s or any of its Affiliates’ conduct of the Business from and after Closing (for clarification, the Liabilities described in this Section 7.2(d) do not include
Pre-Closing Environmental Liabilities); and 
 (e) the Identified Environmental Liabilities. 
 Section 7.3 Method of Asserting Claims. 
 7.3.1 Notification of Claims. Subject to the provisions of Section 8.6, which shall apply to any Tax Claims, if any
Purchaser Indemnified Party or Seller Indemnified Party (each, an “Indemnified Party”) asserts that a Party has become obligated to the Indemnified Party pursuant to Section 7.1 or Section 7.2 above (as so
obligated, an “Indemnifying Party”), or if any suit, action, investigation, claim or proceeding is begun, made or instituted as a result of which the Indemnifying Party may become obligated to the Indemnified Party hereunder, the
Indemnified Party shall notify the Indemnifying Party promptly and shall cooperate with the Indemnifying Party, at the Indemnifying Party’s expense, to the extent reasonably necessary for the resolution of such claim or in the defense of such
suit, action or proceeding, including making available any information, documents and things in the possession of the Indemnified Party. Notwithstanding the foregoing notice requirement, the right to indemnification hereunder shall not be affected
by any failure to give, or delay in giving, notice unless, and only to the extent that, the rights and remedies of the Indemnifying Party shall have been materially prejudiced as a result of such failure or delay. 
 7.3.2 Defense of Claims. In fulfilling its obligations under this Section 7.3, after the Indemnifying Party has
provided each Indemnified Party with a written notice of its agreement to indemnify each Indemnified Party under this Section 7.3, as between such Indemnified Party and the Indemnifying Party, the Indemnifying Party shall have the right
to investigate, defend, settle or otherwise handle, with the aforesaid cooperation, any claim, suit, action or proceeding, brought by a third party in such manner as the Indemnifying Party may reasonably deem appropriate; provided,
however, that (i) counsel retained by the Indemnifying Party is reasonably satisfactory to the Indemnified Party and (ii) the Indemnifying Party will not consent to any settlement or entry of judgment imposing any obligations on any
Indemnified Party, other than financial obligations for which such Person will be indemnified hereunder, unless such Person has consented in writing to such settlement or judgment (which consent may 

  

 48 

 
be given or withheld in its sole discretion) and (iii) the Indemnifying Party will not consent to any settlement or entry of judgment unless, in
connection therewith, the Indemnifying Party obtains a full and unconditional release of the Indemnified Party from all liability with respect to such suit, action, investigation, claim or proceeding. Notwithstanding the Indemnifying Party’s
election to assume the defense or investigation of such claim, action or proceeding, the Indemnified Party shall have the right to employ separate counsel and to participate in the defense or investigation of such claim, action or proceeding, which
participation shall be at the expense of the Indemnifying Party, if (a) on the advice of counsel to the Indemnified Party, use of counsel of the Indemnifying Party’s choice could reasonably be expected to give rise to a material conflict
of interest, (b) the Indemnifying Party shall not have employed counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after notice of the assertion of any such claim or institution
of any such action or proceeding, or (c) if the Indemnifying Party shall authorize the Indemnified Party to employ separate counsel at the Indemnifying Party’s expense. 
 Section 7.4 Limitations of Liability. 
 7.4.1 Indemnification Cap Amount. (i) The Sellers shall have no liability under Section 7.1(a) or under Section 7.1(b) or ARTICLE VIII to the extent the total aggregate
amount of Losses under such Section 7.1(a) and Section 7.1(b) and ARTICLE VIII exceeds $35,000,000 (the “Indemnification Cap Amount”), in the aggregate; provided, however, that the foregoing
limitation shall not apply to any breach of any representation or warranty set forth in Section 3.1.9 or in the special warranty of title set forth in the Deed, and there shall be substituted therefor a limitation in an amount equal to the
Purchase Price; and (ii) the Purchaser shall have no liability under Section 7.2(a) or under Section 7.2(b) or ARTICLE VIII to the extent the total aggregate amount of Losses under such Section 7.2(a)
and Section 7.2(b) and ARTICLE VIII exceeds the Indemnification Cap Amount. 
 7.4.2 Minimum Claim.
Neither Seller shall be required to indemnify the Purchaser with respect to (i) any Loss of less than $25,000 for any single event or occurrence or (ii) any other Loss that would otherwise be indemnifiable under Section 7.1(a)
unless and until the total amount of such other Losses under such Section 7.1(a) exceeds $2,000,000, after which the Sellers shall have the obligation to indemnify for the full amount of any such Losses that exceed such limitation
(subject to the limitations set forth in Section 7.4.1). 
 7.4.3 Insurance Coverage. All Losses
recoverable by an Indemnified Party shall be net of any proceeds such Indemnified Party recovers, or is entitled to recover, under any applicable insurance coverage. 
 7.4.4 Tax Savings. The amount of any Losses shall be reduced by any Tax savings realized by the Indemnified Party arising from the
occurrence or payment of any such Losses in the taxable year in which such Losses are incurred, in any preceding taxable year as a result of the use of net operating loss carrybacks, or in future taxable years. In computing the amount of any such
tax benefit, the Indemnified Party shall be deemed to recognize all other income, gain, loss, deduction, or credit before recognizing any item arising from the incurrence or payment of any indemnified Losses. If the Indemnified Party is expected to
realize a Tax savings in a future year, the Losses shall be reduced by the present value of the Tax savings 

  

 49 

 
expected to be received, determined by discounting the expected savings by the Prime Rate in effect on the date of the Indemnified Party’s incurrence of
the Losses. 
 7.4.5 Indemnification Payment as Purchase Price Adjustment. Any indemnification payment under this
Agreement shall be treated as an adjustment to the Purchase Price for Tax purposes to the maximum extent permitted by applicable Law. 
 Section 7.5 Indemnification in Case of Strict Liability or Indemnitee Negligence. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE INDEMNIFICATION PROVISIONS IN ARTICLE VIII AND IN THIS ARTICLE VII SHALL BE
ENFORCEABLE REGARDLESS OF WHETHER THE LIABILITY IS BASED ON PAST, PRESENT OR FUTURE ACTS, CLAIMS OR LAWS (INCLUDING ANY PAST, PRESENT OR FUTURE ENVIRONMENTAL LAW, FRAUDULENT TRANSFER ACT, OCCUPATIONAL SAFETY AND HEALTH LAW, OR PRODUCTS LIABILITY,
SECURITIES OR OTHER LAW), AND REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT) ALLEGES OR PROVES THE SOLE, JOINT, CONCURRENT, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE OF THE PERSON SEEKING INDEMNIFICATION, OR
THE SOLE, JOINT, OR CONCURRENT STRICT LIABILITY IMPOSED ON THE PERSON SEEKING INDEMNIFICATION. 
 Section 7.6 Exclusive Remedy.
A Party’s right to indemnification provided in this ARTICLE VII, as applicable, is the sole and exclusive remedy of that Party from and after the Closing with respect to any Losses arising out of or relating to the negotiation,
execution, delivery, performance or non-performance of this Agreement, the transactions contemplated hereby or any Liability otherwise arising or resulting from the ownership or operation of the Business, Site, Real Property and/or the Purchased
Assets; it being the Parties’ intent that to the fullest extent permitted by Law, the Parties waive any claim or cause of action they may have against the other Party under any applicable statutory authority, including without limitation
Environmental Laws; provided, however, that nothing in this Section 7.6 shall restrict or prohibit any Party from bringing any action (i) for injunctive relief or specific performance to the extent legally available,
(ii) in the event of fraud by a Party or (iii) to enforce the rights and obligations set forth in the other Transaction Agreements. Each Party waives any provision of applicable Law to the extent it would initiate, limit or restrict the
agreement of the Parties as set forth in this Section 7.6. 
 ARTICLE VIII 
 TAX MATTERS 
 Section 8.1
Representations and Warranties. Sellers represent and warrant to Purchaser, except as set forth on Schedule 8.1, as follows: 
 (a) Each of Rockingham and Former Tax Parent (i) has filed or will file when due all Tax Returns that are required to be filed on or before the Closing Date with respect to the Business and the Purchased Assets
and has paid or will pay in full all Taxes required to be paid with respect to the Business and the Purchased Assets; and (ii) such Tax Returns were prepared or will be prepared in the manner required by all 

  

 50 

 
material applicable Laws. Neither Rockingham nor Former Tax Parent has received any written notice that any Taxes relating to any period prior to the Closing
Date are owing that have not been paid on or before the Closing Date. 
 (b) To Sellers’ Knowledge, true and complete
copies of all Tax Returns and all schedules thereto filed by, or on behalf of, Rockingham and copies of all material written communications to or from any Taxing Authority for all prior taxable years have been made available to Purchaser for
inspection. 
 (c) Neither Rockingham nor Former Tax Parent has extended or waived the application of any statute of
limitations of any jurisdiction regarding the assessment or collection of any Tax of the Sellers with respect to the Purchased Assets. 
 (d) None of the Purchased Assets are subject to any Liens for Taxes, other than Permitted Liens. 
 (e) There are no audits, claims, assessments, levies, administrative or judicial proceedings pending and Seller has received no written notice of any threatened, proposed or contemplated audits, claims, assessments, levies or administrative
or judicial proceedings against Rockingham or with respect to the Purchased Assets by any tax authority. 
 (f) Each of
Rockingham and Former Tax Parent has withheld and paid all Taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, independent contractor, creditor, member or other third party. 
 (g) Other than the Water Supply Agreement, neither Seller is party to any agreement with a Governmental Authority with respect to any
economic or financial incentive affecting the Facility. 
 Section 8.2 Transfer Taxes. Sellers shall bear all sales, use,
transfer, real property transfer, recording and other similar taxes and fees (“Transfer Taxes”), if any, arising out of or in connection with the sale of the Purchased Assets by Sellers or any other transactions pursuant to this
Agreement. Rockingham shall file all necessary documentation and Tax Returns with respect to the Transfer Taxes and cause such Taxes, if any, to be timely paid to the relevant Taxing Authorities. The Parties shall cooperate to comply with all Tax
Return requirements for any and all Transfer Taxes and shall provide such documentation and take such other reasonable actions as may be necessary to minimize the amount of any Transfer Taxes; notwithstanding the foregoing, Purchaser shall not be
obligated to take any action that would cause Purchaser to incur or bear the cost of any Transfer Taxes. For all purposes under this Section 8.2, the Parties agree that the fair market value of Real Property shall be $3,500,000.00.

 Section 8.3 Real and Personal Property Taxes. Real and personal property ad valorem taxes with respect to the Purchased
Assets (“Property Taxes”) will be prorated on a calendar year basis through the Closing Date. Any special assessments or roll-back taxes on or against the Real Property shall be paid by Sellers on or prior to the Closing Date. If
the actual amount of Property Taxes is not known on the Closing Date, such taxes shall be prorated on the basis of the amount of such taxes payable for the prior year, and shall be adjusted between the 

  

 51 

 
Parties when the actual amount of such taxes payable in the year of Closing is known to Purchaser and Sellers. Within thirty (30) days after the
Property Tax liability is known for the calendar year in which the Closing occurs, Purchaser and Sellers shall make such payments or credits between themselves as are necessary so that each Party bears only its pro rata portion of the actual
Property Tax liability for the calendar year in which the Closing occurs. 
 All prorations shall be made as adjustments to the Purchase
Price, provided that to the extent any charge or receipt to be prorated at Closing is not known as of the Closing Date, the Parties shall make the applicable proration and adjusting payments as soon as possible after Closing. 
 Section 8.4 Sellers’ Tax Indemnification. Sellers shall defend, indemnify and hold harmless Purchaser from and against (i) any
and all Taxes imposed on or incurred in respect of the income, business, assets and properties or operations of the Sellers or Former Tax Parent with respect to the Purchased Assets, attributable to any taxable period ending on or prior to the
Closing Date (“Pre-Closing Taxes”), (ii) with respect to any taxable period beginning before and ending after the Closing Date (the “Overlap Period”), any and all Taxes imposed on or incurred in respect of the
income, business, assets and properties or the operations of the Sellers or Former Tax Parent with respect to the Purchased Assets, attributable to the period ending on the Closing Date (“Overlap Period Taxes”), (iii) any and
all Transfer Taxes, and (iv) any Liabilities arising from a breach by Sellers of their covenants in this ARTICLE VIII. For purposes of the Overlap Period, Taxes shall be attributable to the period ending on the Closing Date, and:
(A) in the case of Taxes imposed on a periodic basis or otherwise measured by the level of any item, deemed to be the amount of such Taxes for the entire period (or, in the case of such Taxes determined on an arrears basis, the amount of such
Taxes for the immediately preceding period), multiplied by a fraction the numerator of which is the number of days in the Pre-Closing Tax Period and the denominator of which is the number of days in the entire taxable period; and (B) in the
case of all other Taxes, to the extent of any Taxes that would be payable if the taxable year ended on the Closing Date. 
 Section 8.5
Purchaser Tax Indemnification. Purchaser shall indemnify and hold harmless Sellers from and against (a) any Taxes with respect to the Purchased Assets attributable to the time period after the Closing Date, and (b) any Liability
arising from a breach by Purchaser of its covenants set forth in this ARTICLE VIII. Notwithstanding anything to the contrary in this Agreement, Purchaser shall not be liable for and shall not indemnify Sellers against any liability for any
Transfer Taxes, if any, arising out of or in connection with the sale of the Purchased Assets by Sellers pursuant to this Agreement. 
 Section 8.6 Contests. In the event Purchaser, Sellers or Former Tax Parent receives written notice of any audit, examination, claim, settlement, proposed adjustment, administrative or judicial proceeding, or other matter
(“Tax Claim”) related to any Pre-Closing Taxes, Transfer Taxes or Overlap Period Taxes, Purchaser, Sellers or Former Tax Parent, as the case may be, shall notify the other Parties in writing as soon as reasonably practical (but in
no event more than ten (10) Business Days) after receipt of such notice. If either Seller or Former Tax Parent notifies Purchaser in writing within thirty (30) Business Days following receipt of such written notice that they intend to
exercise their rights pursuant to this Section 8.6, they shall be entitled to control the defense, prosecution, settlement or compromise of such Tax Claim, at their own 

  

 52 

 
expense. Purchaser shall take such action in contesting such Tax Claim as Sellers shall reasonably request from time to time, including the selection of
counsel and experts and execution of powers of attorney. Purchaser shall not make any payments of such Tax Claim for at least thirty (30) days (or such shorter period as may be required by applicable Law) after giving the notice required by
this Section 8.6, shall give the Sellers and Former Tax Parent any information requested relating to such Tax Claim, shall give any Tax Authority any information requested by Sellers or Former Tax Parent relating to such Tax Claim, and
otherwise shall cooperate with and make internal resources available to the Sellers and Former Tax Parent in good faith in order to effectively contest any such Tax Claim. Purchaser shall not settle or otherwise compromise any such Tax Claim with
any Taxing Authority or prosecute such contest to a determination in court or other tribunal or initial or appellate jurisdiction unless instructed to do so by the Sellers or Former Tax Parent. Any of the Sellers or Former Tax Parent may settle or
otherwise compromise any such Tax Claim without Purchaser’s prior written consent, except that if as a result of such settlement or compromise the Taxes payable by Purchaser would be materially increased, none of Sellers or Former Tax Parent
may settle or compromise such matter without Purchaser’s prior written consent, which consent shall not be unreasonably withheld; provided, however, that in the event Purchaser does not promptly consent to such settlement or
compromise, Sellers may pay to Purchaser such settled or compromised amount and Purchaser shall agree to assume all obligations for such Tax Claim Liability. In connection with any proceeding taken with respect to such matters, (i) Sellers
shall keep Purchaser informed of all material developments and events relating to such matters if involving a material liability for Taxes, and (ii) Purchaser shall have the right, at its sole expense, to participate in any such proceedings.
Purchaser shall cooperate with Sellers and Former Tax Parent by giving them and their representatives, on prior reasonable notice, reasonable access and cooperation during normal business hours to all information, books and records pertaining to
Transfer Taxes, Pre-Closing Taxes and Overlap Period Taxes. 
 Section 8.7 Information. After the Closing, Sellers and
Purchaser will make available to each other as requested, all information, records, or documents relating to liability or potential liability for Pre-Closing Taxes, Overlap Period Taxes and Transfer Taxes and will preserve such information, records
or documents until thirty (30) days after the expiration of the applicable statute of limitations (including extensions) with respect to such Taxes. 
 Section 8.8 Tax Returns. Except as otherwise provided in Section 8.3, Sellers shall be responsible for preparing and filing all Tax Returns and paying all Taxes due with respect to the
Purchased Assets relating to Tax periods ending on or prior to the Closing Date. Subject to and without limitation of Purchaser’s rights under Section 8.4, Purchaser shall be responsible for preparing and filing all Tax Returns and
paying all Taxes due with respect to the Purchased Assets relating to Tax periods ending after the Closing Date. Each Party shall cooperate with the other Party with respect to preparing and filing such Tax Returns and shall provide all information
reasonably requested by the other Party necessary to prepare and file such Tax Returns. 
 Section 8.9 Survival of Obligations.
The obligations of the Parties set forth in this ARTICLE VIII shall be unconditional and absolute and shall remain in effect until thirty (30) days after expiration of the applicable statutes of limitation (giving effect to any
extensions or waivers thereof) relating to the Tax or Tax Return in question. 
  

 53 

 Section 8.10 Adjustments to Purchase Price. The Parties hereby agree that any and all
indemnity payments made pursuant to this Agreement shall, to the maximum extent permitted by applicable law, be treated for all Tax purposes as an adjustment to the Purchase Price.

subject to the limitations of Section 7.4 hereof. 
 ARTICLE IX 
 SURVIVAL; NO OTHER REPRESENTATIONS 
 Section 9.1 Survival of
Representations and Warranties. The representations and warranties of Sellers and Purchaser contained in this Agreement shall survive the Closing and shall expire on the date that is eighteen (18) months after the Closing Date.
Notwithstanding the preceding sentence, (i) the representations and warranties contained in Sections 3.1.1, 3.1.2, 3.1.3, 3.1.9, 3.2.1, 3.2.2 and 3.2.3, and the representations and
warranties set forth in the Deed shall survive indefinitely after the Closing, (ii) the representations and warranties contained in ARTICLE VIII shall be governed solely by the terms therein and (iii) the obligations set forth in
Section 8.4 and Section 8.5 shall survive as provided in Section 8.9. The expiration, termination or extinguishment of any representation or warranty pursuant to this Section 9.1 shall not affect the
Parties’ obligations under ARTICLE VII or ARTICLE VIII if the Indemnified Party provided the Indemnifying Party with proper notice of the claim or event for which indemnification is sought prior to such expiration, termination or
extinguishment. 
 Section 9.2 No Other Representations. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT,
IT IS THE EXPLICIT INTENT OF EACH PARTY HERETO THAT, EXCEPT FOR THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN ARTICLE III AND ARTICLE VIII OR IN ANY CERTIFICATE, INSTRUMENT OR DOCUMENT DELIVERED BY SELLERS AT CLOSING,
(i) NEITHER PARTY IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED REPRESENTATION OR WARRANTY AS TO CONDITION, MERCHANTABILITY, USAGE, SUITABILITY OR FITNESS FOR ANY PARTICULAR
PURPOSE WITH RESPECT TO THE FACILITY, OR ANY PART THEREOF, AND (ii) THE PURCHASED ASSETS ARE CONVEYED “AS IS, WHERE IS”. 
 ARTICLE X 
 DISPUTE RESOLUTION 
 Section 10.1 Dispute Resolution. Any dispute or claim arising under this Agreement that is not resolved in the ordinary course of business shall be referred to a panel consisting of a senior executive
(President or a Vice President) of Purchaser and Dynegy, with authority to decide or resolve the matter in dispute, for review and resolution. Such senior executives shall meet and in good faith attempt to resolve the dispute within thirty
(30) days. If the Parties are unable to resolve a dispute pursuant to this Section 10.1, either Party may enforce its rights at law or in equity subject to the provisions of this Agreement, including Section 10.2 below.

 Section 10.2 Submission to Jurisdiction; Waiver of Jury Trial. Each Party hereto
irrevocably submits to the exclusive jurisdiction of the federal court in the State of North Carolina for the purposes of any action arising out of or based upon this Agreement or relating to the subject matter hereof. If, for any reason, the

either Party is required to make any payment under this Agreement on a day other than a Business Day, the date of payment shall be extended to the next Business Day. In the event a Party does not make any payment required or approved by the Parties
under this Agreement on or before the due date, interest on the unpaid amount shall be due and paid at a rate that is the lesser of (a) the prime rate under “Money Rates” as reported in the Wall Street Journal on the first Business

 Section 12.3 Entire Agreement. This Agreement and the Transaction Agreements supersede all prior discussions and
agreements between the Parties with respect to the subject matter hereof and thereof, including, in each case, all schedules and exhibits thereto, and contain the sole and entire agreement between the Parties hereto with respect to the subject
matter hereof and thereof. 
 Section 12.4 Expenses. Except as otherwise expressly provided in this Agreement, whether or not
the transactions contemplated hereby are consummated, each Party will pay its own costs and expenses incurred in connection with the negotiation, execution and performance under this Agreement and the Transaction Agreements and the transactions
contemplated hereby and thereby; provided, however, that Sellers, jointly and severally, shall promptly reimburse Purchaser for one-half of the HSR Act filing fee. 
 Section 12.5 Public Announcements. Sellers and Purchaser will not issue or make any press releases or similar public announcements
concerning this Agreement or the transactions contemplated hereby without the consent of the other, which consent shall not be unreasonably withheld. If either Party is unable to obtain the approval of its press release or similar public statement
from the other Party and such press release or similar public statement is, in the opinion of legal counsel to such Party, required by Law in order to discharge such Party’s disclosure obligations, then such Party may make or issue the legally
required press release or similar public statement and promptly furnish the other Party with a copy thereof. Sellers and Purchaser will also obtain the other Party’s prior approval, which approval shall not be unreasonably withheld, of any
press release to be issued immediately following the execution of this Agreement or the Closing announcing either the execution of this Agreement or the consummation of the transactions contemplated by this Agreement. 
 Section 12.6 Confidentiality. Each Party hereto will hold, and will use commercially reasonable efforts to cause its Related Persons to
hold, in strict confidence from any Person (other than any such Related Persons), unless (i) compelled to disclose by judicial or administrative process (including in connection with obtaining the necessary approvals of this Agreement and the
transactions contemplated hereby of Governmental Authorities) or by other 

  

 57 

 
requirements of Law or necessary or desirable to disclose in order to obtain the NCUC Approvals and the FERC Approvals or (ii) disclosed in an action or
proceeding brought by a Party hereto in pursuit of its rights or in the exercise of its remedies hereunder, all documents and information concerning the other Party or any of its Related Persons furnished to it by the other Party or such other
Party’s Related Persons in connection with this Agreement or the transactions contemplated hereby, except to the extent that such documents or information can be shown to have been (a) previously known by the Party receiving such documents
or information, (b) in the public domain (either prior to or after the furnishing of such documents or information hereunder) through no fault of such receiving Party or (c) later acquired by the receiving Party from another source if the
receiving Party is not aware that such source is under an obligation to another Party hereto to keep such documents and information confidential. In the event the transactions contemplated hereby are not consummated, upon the request of the other
Party, each Party hereto will, and will use commercially reasonable efforts to cause its Related Persons to, promptly (and in no event later than five (5) Business Days after such request) destroy or cause to be destroyed all copies of
confidential documents and information furnished by the other Party in connection with this Agreement or the transactions contemplated hereby and destroy or cause to be destroyed all notes, memoranda, summaries, analyses, compilations and other
writings related thereto or based thereon prepared by the Party furnished such documents and information or its Related Persons. The obligations contained in this Section 12.6 shall not survive Closing or, if this Agreement is terminated
pursuant to ARTICLE VI, such obligations shall survive for one year following the termination of this Agreement. 
 Section 12.7
Waivers. 
 12.7.1 Grant of Waivers. 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. All remedies, either under this Agreement or by Law or
otherwise afforded, will be cumulative and not alternative. 
 12.7.2 Exercise of Remedies. No failure or delay of any
Party, in any one or more instances, (i) in exercising any power, right or remedy (other than failure or unreasonable delay in giving notice of default) under this Agreement or (ii) in insisting upon the strict performance by the other
Party of such other Party’s covenants, obligations or agreements under this Agreement, shall operate as a waiver, discharge or invalidation thereof, nor shall any single or partial exercise of any such right, power or remedy or insistence on
strict performance, or any abandonment or discontinuance of steps to enforce such a right, power or remedy or to enforce strict performance, preclude any other or future exercise thereof or insistence thereupon or the exercise of any other right,
power or remedy. The covenants, obligations, and agreements of a defaulting Party and the rights and remedies of the other Party upon a default shall continue and remain in full force and effect with respect to any subsequent breach, act or
omission. 
  

 58 

 Section 12.8 Amendment. This Agreement and any of the Transaction Agreements may be
amended, supplemented or modified only by a written instrument duly executed by or on behalf of each Party hereto. 
 Section 12.9 No
Construction Against Drafting Party. The language used in this Agreement is the product of both Parties’ efforts, and each Party hereby irrevocably waives the benefits of any rule of contract construction that disfavors the drafter of a
contract or the drafter of specific words in a contract. 
 Section 12.10 No Third-Party Beneficiary. The terms and provisions
of this Agreement are intended solely for the benefit of each Party hereto and their respective successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person. 

Section 12.11 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 12.12 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 hereto under this Agreement will not be materially and adversely affected thereby, (a) such provision will be fully severable, (b) this
Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (c) 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 (d) Purchaser and Sellers shall negotiate an equitable adjustment in the provisions of the Agreement with a view toward effecting the purposes of the Agreement,
and the validity and enforceability of the remaining provisions, or portions or applications thereof, shall not be affected thereby. 
 Section 12.13 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NORTH CAROLINA APPLICABLE TO A CONTRACT EXECUTED AND PERFORMED IN SUCH STATE, WITHOUT GIVING EFFECT TO
THE CONFLICTS OF LAWS PRINCIPLES THEREOF. 
 Section 12.14 Court Costs; Interest. With respect to any court proceeding between
the Parties, the non-prevailing Party shall pay the prevailing Party (i) all court costs, and (ii) pre- and post-judgment interest on the amount awarded from the date of the applicable breach until paid. 
 Section 12.15 No Assignment; Binding Effect. Neither this Agreement nor any right, interest or obligation hereunder may be assigned by any
Party hereto without the prior written consent of the other Party hereto and any attempt to do so will be void, except for assignments and transfers by operation of Law. This Agreement is binding upon, inures to the benefit of and is enforceable by
the Parties and their respective successors and assigns.

 Section 12.16 Counterparts. This Agreement may be executed in any number of counterparts,
