 Exhibit 10.9 
 RITA Medical Systems 
 2006 Management Performance Incentive Plan 
 PURPOSE 
 The purpose of the 2006 Management
Performance Incentive Plan (PIP) is to reward eligible employees for achieving RITA Medical Systems business plan goals and provide a means for management to share in the company’s success. 
 The PIP has two independent and unrelated mutually exclusive parts: 
 1.
Financial Achievement Plan. The Compensation Committee has approved potential cash bonus payments to employees of approximately $830,000 in the aggregate (prior to any changes which will be allowed for raises, new hires or promotions to
become eligible, or of a change of levels or performance award percentages) under the Financial Achievement Plan (The “Financial Plan”), subject to acceleration in certain circumstances as discussed below. Under the Financial Plan, if the
Company’s actual performance meets or exceeds certain of its target revenue and pro forma income/loss goals for the first and/or second half of the year ending December 31, 2006, the Company’s executive officers, senior directors,
directors and managers (the “Employee Group”), a group consisting of approximately 30 employees, will receive cash incentive bonus payments within a defined range, paid on a semi-annual basis. The Financial Plan provides that if the
Company meets certain target revenue and pro forma income/loss goals in the applicable six month period, these employees would receive a cash bonus ranging from 0% to 40% (depending on the level of the eligible employee and other factors) of such
employee’s salary for such six month period. In addition, if the Company exceeds certain other target revenue and pro forma income/loss goals in the applicable six month period, these employees would receive an additional accelerated cash bonus
ranging from 0% to 40% (depending on the level of the eligible employee and other factors) of such employee’s salary for such six month period. The Financial Plan also provides that the Company must maintain certain cash balances as of
June 30, 2006 and December 31, 2006 in order for the employees to be eligible to receive any of the cash incentive bonus payments under the Financial Plan. Finally, the Financial Plan provides for a year end adjustment to the cash bonus
payment for an applicable six month period in certain circumstances. 
 2. Program Milestone Plan. The Compensation Committee has approved potential
cash bonus payments to employees totaling up to a maximum of $400,000 in the aggregate under the Program Milestone Plan (the “Milestone Plan”). Under the Milestone Plan, the Employee Group will receive an aggregate of up to $400,000
to be paid in cash after December 31, 2006, if specific quarterly project development milestones were achieved during fiscal 2006. Failure by the Employee Group to achieve the financial goals set forth in the Financial Plan will not have any
effect on the eligibility of the Employee Group for the potential cash bonus payments under the Milestone Plan. The Compensation Committee reserves the right to adjust or eliminate the compensation amounts in the event that the project development
milestones are not met in a timely manner. 
 Additional Information 
 Participation in the PIP is not a contract of employment and does not alter the employment-at-will status of any participant. Management along with the Compensation Committee of the Board of Directors reserves the
right to terminate the PIP at any time.Purchase and Sale Agreement

 (a) The Parties will, in order to consummate the transactions contemplated hereby, (i) take all
commercially reasonable steps necessary, and proceed diligently and in good faith and use all commercially reasonable efforts, as promptly as practicable, to obtain the Seller Approvals, Company Consents and Buyer Approvals in form and substance
reasonably satisfactory to Seller and Buyer, and to make all required filings with, and to give all required notices to, Governmental Authorities (provided that HSR Act filings and attachments need not be exchanged or preapproved by the other party

Governmental Authorities or other Persons as such Governmental Authorities or other Persons may reasonably request in connection therewith. 
 (b) The Parties will provide prompt notification to each other when any such approval referred to in Section 6.1(a) is obtained, taken, made, given or denied, as applicable, and will advise each other of any
material communications with any Governmental Authority or other Person regarding any of the transactions contemplated by this Agreement. 
  

 33 

 (c) In furtherance of the foregoing covenants: 
 (i) Each Party shall prepare, as soon as is practical following the execution of this Agreement, all necessary filings in connection with

any other assets or lines of business of Buyer or its Affiliates in order to remedy any material competition concerns that any Governmental Authority may have. The entry by any Governmental Authority in any legal proceeding of a governmental order
permitting the consummation of the transactions contemplated hereby but requiring any of the Assets or lines of business of Buyer or its Affiliates to be held separate or sold or disposed of thereafter (including the business and Assets of the

of such guaranty, Buyer shall pay Seller or Seller’s designee a fee of 1.0% (on a per annum basis) on the amount under the heading “Subject Amount” on Schedule 6.5(a) with respect to each Continuing Support Obligation, which
fee shall increase by an additional 0.5% (on a per annum basis) on each six month anniversary of the Closing Date (or such effective date, as applicable) with respect to any such Continuing Support Obligation that remains outstanding, up to a
maximum fee of 3.0% (on a per annum basis); 
 (f) Notwithstanding anything in this Agreement to the contrary, Seller and the
Non-Company Affiliates may not terminate any Continuing Support Obligations at any time after the Closing Date until such Continuing Support Obligations terminate or expire by their terms or by consent of the applicable beneficiary or are replaced
pursuant to this Section 6.5. 
 (g) During the Interim Period, Buyer shall have the right to contact and have
discussions with each beneficiary of a Support Obligation in order to satisfy its obligations under this Section 6.5; provided, however, that Buyer shall give Seller prior notice before making any such contact. 
  

 40 

 (h) From and after the Closing, Buyer shall indemnify Duke Capital LLC for any
liabilities, losses, costs or expenses incurred by it under (i) any guaranty issued by it pursuant to (A) the requirements of Section 2.4(m) of the Cooperation Agreement in respect of the Port Leases and Permits (as defined in the
Cooperation Agreement) or (B) the requirements of Section 13.14 of the Cooperation Agreement, in either case where such liabilities, losses, costs or expenses are incurred due to a breach of the Cooperation Agreement by Duke South Bay or a
breach of such Port Leases and Permits and (ii) the Siemens Guaranty, except to the extent any such liabilities, losses, costs or expenses with respect to the Siemens Guaranty constitute an Excluded Liability described as the second item under
the heading “Bridgeport” on Schedule 6.6. 
 6.6 Excluded Items. Notwithstanding anything in this Agreement to
the contrary, Buyer and Seller agree that the Purchased Assets shall exclude those items listed on Schedule 6.6 (collectively, the “Excluded Items”), Seller shall retain all benefits and liabilities with respect to the
Excluded Items, and Seller shall, prior to the Closing Date, use commercially reasonable efforts to cause the Project Companies to distribute, transfer or assign each Excluded Item to Seller or a Non-Company Affiliate. Buyer acknowledges that the
inability of Seller to have any Excluded Item distributed, transferred or assigned from any Project Company for any reason shall not delay Closing and any Excluded Item that Seller is unable to so distribute, transfer or assign by the Closing shall
be referred to as a “Non-Transferred Excluded Item.” After the Closing Date with respect to each Non-Transferred Excluded Item, Buyer shall permit Seller to exclusively direct and manage each Project Company’s
participation in all negotiations, arbitrations, litigation, claims, and/or bankruptcy or other proceedings involving such Non-Transferred Excluded Item, whether existing on the Closing Date or arising thereafter. Buyer shall also permit Seller to
settle or compromise on behalf of any Project Company any Non-Transferred Excluded Item in Seller’s sole discretion, and shall promptly pay Seller any proceeds or recoveries received in connection with any Non-Transferred Excluded Item. Buyer
shall, at Seller’s expense: (a) cause any Person under its control with knowledge of relevant facts pertaining to any Non-Transferred Excluded Item to provide assistance to Seller as reasonably requested by Seller; and (b) provide any
relevant books, records, or other information of any Project Company to Seller and access to each Project site, as reasonably requested by Seller, in connection with any Non-Transferred Excluded Item. 
 6.7 Employee and Benefit Matters. (a) Schedule 6.7(a) sets forth a list of certain employees of Seller or its Affiliates (the
“Available Employees”) who have provided services relating to the Projects and that Seller and such Affiliates will make available to Buyer to discuss potential employment with Buyer (which discussions the Parties agree shall
not violate Section 6.7(c)). The list of Available Employees set forth on Schedule 6.7(a) identifies which Available Employees are covered by a collective bargaining agreement or other agreement with any labor representative of the
Available Employees (the “Union Employees”). Within five Business Days following the execution of this Agreement, Seller has provided to Buyer (i) certain aggregated employee information (with ranges and averages)
relating to employee compensation and benefits of the Available Employees and (ii) specific information relating to each Available Employee (including salary) and as of a specified date regarding such employee’s name (to the extent
permitted by any applicable Contract and Laws), job title and work location. As soon as administratively practicable after Buyer provides Seller with a list of the Available Employees who have accepted an employment offer from Buyer in accordance
with Section 6.7(b), Seller shall provide to Buyer, with respect to each Available Employee on such list and 

  

 41 

 
subject to the consent of any such employee that Seller determines is required by Law, information as of a specified date regarding such employee’s
current base salary or wages, hire date, vacation and sick leave accrual rates and severance benefits. 
 (b) Within
forty-five (45) days after the execution of this Agreement, Buyer shall make offers of employment to each of the Available Employees that Buyer desires to employ after Closing and such offer shall include terms and provisions determined by
Buyer that are consistent with the provisions of this Section 6.7; provided, however, that (i) the base salary/wage rate that Buyer extends to an Available Employee for the initial 12 consecutive month period of employment with
Buyer or an Affiliate of Buyer shall not be less than the Available Employee’s base salary/wage rate that was in effect for the Available Employee immediately prior to the Closing Date for employment with Seller or an Affiliate of Seller and
(ii) each offer that Buyer extends to a Union Employee shall permit such Union Employee to maintain his or her work location (as of the Closing Date) for the 12 month period after the Closing Date. Within forty-five (45) days after the
execution of this Agreement, Buyer shall provide Seller with a list of the Available Employees to whom it has made offers of employment. Within sixty (60) days after the execution of this Agreement, Buyer shall notify Seller as to each
Available Employee who has accepted employment with Buyer or any of its Affiliates (each, a “Continued Employee”), which acceptance may be conditioned upon the occurrence of the Closing and other typical hiring policies, and
each Available Employee who has rejected Buyer’s offer of employment. Buyer shall indemnify and hold harmless Seller and its Affiliates with respect to all claims and liabilities directly relating to or arising out of Buyer’s employee
selection and employment offer process described in this Section 6.7(b) (including any claim of discrimination or other illegality in such selection and offer process). The employment with Buyer or an Affiliate of Buyer of each Available
Employee who accepts such employment shall be effective as of the Closing Date; provided, however, that on such date such Available Employee is actively at work or is on a previously scheduled and approved (by Seller or an Affiliate of
Seller) paid time-off or other paid leave of absence (other than a military leave of absence or a leave pursuant to which the individual is eligible to receive long-term disability benefits under a Seller Plan). Notwithstanding the foregoing, with
respect to each Available Employee who fails to become a Continued Employee as of the Closing Date because he or she did not satisfy the requirements of the preceding sentence as of the Closing Date, Buyer shall, or shall cause an Affiliate of Buyer
to, at the time such Available Employee is ready and available to return to active employment status, provide such Available Employee with employment in a position comparable to that which the individual had prior to the commencement of his or her
absence from active employment. Each Available Employee who becomes employed by Buyer or an Affiliate of Buyer pursuant to the preceding sentence shall be considered a Continued Employee for purposes of this Agreement, except that transitional
matters addressed in this Section 6.7 shall apply with respect to such employee as of the date of his or her commencement of employment with Buyer or an Affiliate of Buyer (rather than as of the Closing Date). Nothing in the foregoing shall
affect the right of Seller, or any Affiliate of Seller, to terminate the employment of an Available Employee for any reason or at any time. 
 (c) Buyer agrees, if the Closing has not occurred, until the date that is two years from and after the date of termination of this Agreement pursuant to Section 9.1, not to employ, and to cause its Affiliates not
to employ, any Available Employees without Seller’s prior written consent. Buyer agrees that neither it nor any of its Affiliates will, directly or 

  

 42 

 
indirectly, in any manner whatsoever, solicit for hire or employment any officer or employee of the Seller or any of its Affiliates which Buyer or its
Affiliates learned of in connection with the acquisition contemplated hereby for a period of two years after the date of this Agreement; provided, however, that this sentence shall not apply to any solicitation (or any hiring as a result of
any solicitation) that consists of advertising in a newspaper or periodical of general circulation or through the Internet. 
 (d) Effective as of the Closing Date, the Continued Employees shall cease to participate in all “employee benefit plans” within the meaning of Section 3(3) of ERISA of Seller or its Affiliates providing benefits to any
Continued Employees (the “Seller Plans”). Buyer shall not assume any of the Seller Plans. 
 (e) From
and after the Closing Date and subject to the provisions set forth in the proviso to the first sentence of Section 6.7(b), Buyer shall cause each Continued Employee to be provided with compensation and benefits on a basis substantially similar
to those provided to similarly situated employees of Buyer and its Affiliates; provided, however, that if the employment of any Continued Employee is terminated by Buyer or an Affiliate of Buyer for a reason other than cause within one
year after the commencement of such employment, then Buyer shall provide such Continued Employee with severance benefits equal to the greater of (i) the severance benefits described in the Severance Plan that would have been provided to such
employee if his or her employment had been terminated under circumstances entitling such employee to benefits under the Severance Plan or (ii) the severance benefits described in the severance plan that Buyer and its Affiliates make available
to their similarly situated employees and that would have been provided to such employee if his or her employment had been terminated under circumstances entitling such employee to benefits under such severance plan. Notwithstanding the foregoing,
Buyer shall cause each Continued Employee and his or her eligible dependents (including all such Continued Employee’s dependents covered immediately prior to the Closing Date by a group health plan maintained by Seller or an Affiliate of
Seller) to be covered under a group health plan maintained by Buyer or an Affiliate of Buyer that (1) provides major medical and dental benefits coverages to the Continued Employee and such eligible dependents effective immediately upon the
Closing Date and (2) credits such Continued Employee, for the year during which such coverage under such group health plan begins, with any deductibles and co-payments already incurred during such year under a group health plan maintained by
Seller or an Affiliate of Seller; provided, however, that for purposes of applying this clause (3) with respect to any Continued Employee, the Continued Employee shall be responsible for providing the necessary information to Buyer based
on explanation of benefit forms received by the Continued Employee from the group health plan maintained by Seller or an Affiliate of Seller. From and after the Closing Date, Buyer shall (and shall cause the Project Companies and their respective
Affiliates, as the case may be to) recognize each Continued Employee’s years of company service prior to the Closing Date with Seller and its Affiliates and any other Person that was acquired by Seller or an Affiliate of Seller (whether through
purchase, merger or other combination) for purposes of terms of employment, compensation and eligibility, vesting or other benefit/coverage eligibility (including eligibility for retiree benefits/coverages), benefit accrual and benefit determination
under all employee benefit and compensation plans and programs maintained after the Closing by Buyer, the Project Companies, and their respective Affiliates in which such Continued Employee is permitted to participate (other than for benefit accrual
purposes under any defined benefit pension plan), including paid 

  

 43 

 
vacation, paid sick time and severance benefits. Buyer shall cause each employee welfare benefit plan or program sponsored by Buyer or an Affiliate of Buyer
that the Continued Employees may be eligible to participate in on or after the Closing Date to waive any preexisting condition exclusion or restriction with respect to participation and coverage requirements applicable to Continued Employees. From
and after the Closing Date, Buyer shall (and shall cause the Project Companies and their respective Affiliates, as the case may be to) recognize and give each Continued Employee credit for his or her accumulated sick leave balance as of the Closing
Date under the sick leave program maintained by Seller and its Affiliates. 
 (f) Claims of Continued Employees and their
eligible beneficiaries and dependents for medical, dental, prescription drug, life insurance or other welfare benefits (“Welfare Benefits”) (other than disability benefits) that are incurred before the Closing Date shall be
the sole responsibility of Seller and the Seller Plans. Claims of Continued Employees and their eligible beneficiaries and dependents for Welfare Benefits (other than disability benefits) that are incurred from and after the Closing Date shall be
the sole responsibility of Buyer and its Affiliates. For purposes of this paragraph, a medical/dental claim shall be considered incurred on the date when the medical/dental services are rendered or medical/dental supplies are provided, and not when
the condition arose or when the course of treatment began. Claims of individuals receiving long-term disability benefits under a Seller Plan as of the Closing Date shall be the sole responsibility of Seller and the Seller Plans. Except as provided
in the preceding sentence, claims of Continued Employees and their eligible beneficiaries and dependents for short-term or long-term disability benefits from and after the Closing Date shall be the sole responsibility of Buyer and its Affiliates
(without regard to whether the circumstances giving rise to such claim occurred before, on or after the Closing Date). 
 (g)
All claims for health care and dependent care flexible spending account benefits submitted after the Closing Date for expenses incurred prior to the Closing Date by Continued Employees shall be paid by Seller’s or its Affiliates’ health
care and dependent care flexible spending account plan to the extent permitted in accordance with the terms of such plan. 
 (h) Claims for workers’ compensation benefits arising out of occurrences prior to the Closing Date shall be the responsibility of Seller. Claims for workers’ compensation benefits for Continued Employees arising out of occurrences
on or after the Closing Date shall be the responsibility of Buyer. 
 (i) Notwithstanding anything to the contrary in
Section 6.7, Buyer shall have the right to use a third party or an Affiliate of Buyer operator to hire Available Employees and to perform certain actions on behalf of Buyer under Section 6.7, provided that in no event will such use of or
performance by a third party operator release Buyer from any of its obligations under Section 6.7. 
 6.8 Termination of Certain
Services and Contracts. Notwithstanding anything in this Agreement to the contrary, prior to the Closing, Seller shall (i) terminate, sever, or assign to Seller or a Non-Company Affiliate effective upon or before the Closing any
services provided to any of the Project Companies by Seller or a Non-Company Affiliate, including the termination or severance of insurance policies (including those policies referred to in Section 6.10), Tax services, legal services and
banking services (to include the severance of any centralized 

  

 44 

 
clearance accounts), (ii) use commercially reasonable efforts to terminate or assign to Seller or a Non-Company Affiliate each Contract listed on
Schedule 6.8 , and (iii) cause all Claims or obligations (contingent or otherwise) between any Project Company, on one hand, and Seller or any Non-Company Affiliate, on the other, to be released effective immediately prior to Closing
(collectively such Contracts listed, the “Terminated Contracts”). 
 6.9 Indebtedness; Spare Parts;
Distributions. Notwithstanding anything in this Agreement to the contrary: 
 (a) Except for the South Bay Lease
Facility, prior to or at the Closing, Seller shall cause any and all Indebtedness of the Project Companies to be paid in full and any and all Liens securing any such Indebtedness to be released such that Buyer shall take title to the Project
Companies free of any such Indebtedness or any such Liens. 
 (b) Seller shall have the right to cause the Project Companies
to pay cash dividends, make cash distributions and assign accounts receivable to Seller or its Affiliates at any time prior to the Closing. After the Closing, Buyer shall promptly remit to Seller any amounts received by Buyer or the Project
Companies as payment on accounts receivable of any Project Company that such Project Company assigned to Seller or a Non-Company Affiliate and that was not reflected in the Adjusted Net Working Capital of the Project Companies as of the Closing
Date. 
 6.10 Insurance. Seller shall maintain or cause to be maintained in full force and effect the insurance policies
described on Schedule 4.17 until the Closing. All such insurance coverage shall be terminated as of the Closing, except any insurance described on Schedule 4.17 that relates to the Griffith Project and that is not maintained by Seller or a
Non-Company Affiliate. Buyer shall be solely responsible for providing insurance to the Project Companies for any event or occurrence after the Closing. Within 30 days after the execution of this Agreement, Buyer shall prepare and file with the
California Department of Toxic Substances Control (“DTSC”) all documentation necessary to achieve compliance by Buyer, effective as of Closing, with the financial responsibility requirements of Division 4.5, Title 22 of the
California Code of Regulations applicable to the Morro Bay, Moss Landing, South Bay and Oakland Projects. Buyer shall use its commercially reasonable efforts to expedite DTSC review and approval of such documentation and DTSC release of Seller and
any Non-Company Affiliates from such financial responsibility. 
 6.11 Casualty. If any of the Purchased Assets is damaged or
destroyed by casualty loss after the date hereof and prior to the Closing, and (x) the cost of restoring such damaged or destroyed Purchased Assets to a condition reasonably comparable to their prior condition and (y) the amount of any
lost profits reasonably expected to accrue after Closing as a result of such damage or destruction to such Purchased Assets (net of and after giving effect to any insurance proceeds available to the Project Companies for such restoration and lost
profits and any tax benefits related thereto) (such costs and lost profits with respect to any Purchased Assets, the “Restoration Cost”, provided, that with respect to the Purchased Assets of Southwest Power Partners, ED
Services, or Griffith Energy, “Restoration Cost” shall include only one-half (1/2) of such costs) is greater than $2,500,000 but does not exceed 10% of the Base Purchase Price, Seller may elect to reduce the amount of the Purchase
Price by the estimated Restoration Cost (as 

  

 45 

 
estimated by a qualified firm reasonably acceptable to Buyer and Seller), by notice to Buyer, and such casualty loss shall not affect the Closing. If Seller
does not make such an election within 45 days after the date of such casualty loss, Buyer may elect to terminate this Agreement within 10 Business Days after the end of such 45 day period by written notice to Seller. If the Restoration Cost is in
excess of 10% of the Base Purchase Price, Seller may, by notice to Buyer within 45 days after the date of such casualty loss, elect to (a) reduce the Purchase Price by the estimated Restoration Cost (as estimated by a qualified firm reasonably
acceptable to Buyer and Seller) or (b) terminate this Agreement, in each case by providing written notice to Buyer; provided, however, that if Seller does not elect to terminate this Agreement as provided in this sentence, then Buyer
may, by written notice to Seller, terminate this Agreement within ten Business Days of receipt by Buyer of Seller’s notice regarding its election. If the Restoration Cost is $2,500,000 or less, (i) neither Buyer nor Seller shall have the
right or option to terminate this Agreement and (ii) there shall be no reduction in the amount of the Purchase Price. 
 6.12
Condemnation. If any of the Purchased Assets is taken by condemnation after the date hereof and prior to the Closing and such Purchased Assets have the sum of (x) a condemnation value and (y) to the extent not
included in preceding clause (x), the amount of any lost profits reasonably expected to accrue after Closing as a result of such condemnation of such Purchased Assets (net of and after giving effect to any condemnation award any tax benefits related
thereto) (such sum with respect to any Purchased Assets, the “Condemnation Value”, provided, that with respect to the Purchased Assets of Southwest Power Partners, ED Services, or Griffith Energy, “Condemnation
Value” shall include only one-half (1/2) of such value)) greater than $2,500,000 but do not have a Condemnation Value (as determined by a qualified firm reasonably acceptable to Buyer and Seller) in excess of 10% of the Base Purchase
Price, Seller may elect to reduce the Purchase Price by such Condemnation Value (less the amount of any condemnation award and tax benefits related thereto) by notice to Buyer, and such condemnation shall not affect the Closing. If Seller does not
make such an election within 45 days after the date of such condemnation, Buyer may elect to terminate this Agreement within 10 Business Days after such 45 day period by written notice to Seller. If the Condemnation Value is in excess of 10% of the
Base Purchase Price, Seller may, by notice to Buyer within 45 days after the award of condemnation proceeds, elect to (a) reduce the Purchase Price by such Condemnation Value (after giving effect to any condemnation award available and tax
benefits related thereto) or (b) terminate this Agreement, in each case by providing written notice to Buyer; provided, however, that if Seller does not elect to terminate this Agreement as provided in this sentence, then Buyer may, by
written notice to Seller, terminate this Agreement within 10 Business Days of receipt by Buyer of Seller’s notice regarding its election. If the Condemnation Value is $2,500,000 or less, (A) neither Buyer nor Seller shall have the right or
option to terminate this Agreement and (B) there shall be no reduction in the amount of the Purchase Price. 
 6.13 Transfer
Taxes. Notwithstanding anything in this Agreement to the contrary, Seller and Buyer shall each pay any Transfer Taxes imposed on it by Law as a result of the sale of the Company Interests, but, notwithstanding such requirement
at Law, each of Seller and Buyer shall bear half of the total of all such Transfer Taxes. Accordingly, if either Party is required at Law to pay more than its half of any such Transfer Taxes, the other Party shall promptly reimburse such first Party
for amounts in excess of such half. Seller and Buyer shall timely file their own Transfer Tax returns as required by Law and shall notify the other Party 

  

 46 

 
when such filings have been made. Seller and Buyer shall cooperate and consult with each other prior to filing such Transfer Tax returns to ensure that all
such returns are filed in a consistent manner. Seller’s Transfer Tax obligation under this Section 6.13 is limited to those Transfer Taxes arising from Buyer’s purchase of the Company Interests and the Purchased Assets and any actions
occurring prior to the Closing, and Buyer is solely responsible for any Transfer Taxes arising from any action to dissolve, terminate or restructure any Project Company or to convey, distribute or transfer any assets, properties or other rights by
deed, bill of sale or otherwise to or from any Project Company after the Closing. 
 6.14 Transition Services
Arrangements. 
 (a) For a period of three months following the Closing Date, upon the request from time
to time from Buyer, Seller shall provide or cause to be provided to the Project Companies or Buyer those services listed on Schedule 6.14(a) as are requested by Buyer (but Seller shall have no obligation to provide any such services that were
provided by any employee of Seller that is hired by Buyer, its Affiliates or the Project Companies on or after the Closing) (the services listed thereon, collectively, the “Transition Services”). Seller shall and shall cause
its Affiliates to perform any Transition Services provided hereunder in good faith, on a commercially reasonable basis, (i) in all material respects in compliance with all Laws and (ii) to the extent not inconsistent therewith, in
substantially the same quality and manner as the same or comparable services were provided by Seller or its Affiliates to the Project Companies during the one year preceding the Closing Date; provided, however, that (x) Seller shall have no
liability to Buyer or its affiliates for any acts or omissions of it or of any Non-Company Affiliate in connection with this Section 6.14 and the Transition Services (and Buyer shall indemnify and hold harmless Seller and the Non-Company
Affiliates from and against any and all losses, liabilities and expenses relating to the Transition Services) except to the extent of the gross negligence or willful misconduct of Seller or such Non-Company Affiliate and (y) the exclusive
remedies of Buyer and its Affiliates against Seller and the Non-Company Affiliates for any breach of this Section 6.14 shall be limited to termination (effective upon notice) of the affected Transition Service and monetary damages, which in no
event shall exceed the amount paid to Seller and the Non-Company Affiliates pursuant to Section 6.14(b). Buyer also acknowledges that certain personnel of Seller and/or the Non-Company Affiliates may leave the employment of such Persons or
terminate their employment or contract with such Persons during the period during which Seller shall provide Transition Services hereunder, and that the loss of such personnel may materially impede Seller’s ability to perform its obligations
hereunder; Seller makes no representation or warranty regarding the ability of Seller and/or the Non-Company Affiliates to retain any such employees or subcontractors and neither Seller nor any of its Affiliates shall have any liability as to the
result of the loss of any such employees. 
 (b) Buyer, upon not less than 30 days’ written notice, at any time and from
time to time may, as of the date set forth in such notice (which may not precede the end of such 30-day period without Seller’s approval), reduce or terminate its right to receive (and Seller’s associated obligations to provide or cause
the provision of) any or all of the applicable Transition Services. Buyer shall reimburse Seller for the reasonable costs or expenses actually incurred by Seller or any Non-Company Affiliate attributable to the provision of Transition Services,
including any allocations of overhead expenses of Seller or any Non-Company Affiliate and any retention payments required to retain employees who provide Transition Services (such costs and 

  

 47 

 
expenses, the “Direct Costs”). No later than the 15th Business Day after each calendar month during which Seller provided Transition Services, beginning with the calendar month immediately following the Closing,
Seller shall submit an invoice to the Buyer for the Direct Costs incurred during such calendar month. If the Closing occurs on a day other than the last day of a month, the invoice shall be only for those Transition Services provided from such date
until the end of the month in which the Closing took place. Buyer shall pay or cause to be paid the undisputed portion of each such invoice it receives within 15 days after its receipt. 
 6.15 Morro Bay Lease Consent. Notwithstanding anything to the contrary in this Agreement: 
 (a) If each condition to Closing set forth in Articles VII and VIII has been fulfilled other than the Company Consents with respect to the
Morro Bay Project identified with an asterisk on Schedule 4.2 (any such Company Consents, the “Outstanding Consent”), Seller may, at its election, require Buyer to proceed with the Closing with respect to the Company
Interests other than the Morro Bay Company Interest (the “Initial Company Interests”). If Seller so elects to proceed with Closing with respect to the Initial Company Interests, it shall provide Buyer with written notice of
such election, and the Closing with respect to the Company Interests other than the Morro Bay Company Interest (the “Initial Closing”) shall occur on the third Business Day after delivery of such notice to Buyer (such date,
the “Initial Closing Date”). The terms and procedures for the Initial Closing shall be the same as for the Closing provided for herein, except that (i) Seller shall not be obligated to convey, and Buyer shall not be
obligated to accept, the Morro Bay Company Interest, (ii) the portion of the Purchase Price payable at the Initial Closing shall be equal to the amount set forth in Section 2.2(a) less the Morro Bay Purchase Price plus or minus the amounts
calculated pursuant to Sections 2.2(b) and (c) (but excluding from such calculation any amounts attributable to the Morro Bay Project) and (iii) the Morro Bay Project and the Morro Bay Company Interest shall be deemed to be excluded from
each representation and warranty made by Seller at the Initial Closing. Each reference to “the Closing” or “the Closing Date” in a provision hereof as such provision relates to any of the Initial Company Interests (and the
Projects associated therewith) shall be deemed to be a reference to “the Initial Closing” or “the Initial Closing Date,” respectively. If the Initial Closing has occurred, no Party may terminate this Agreement pursuant to Article
IX except with respect to the Morro Bay Company Interest and the Morro Bay Project and the obligation to close with respect thereto. 
 (b) If the Parties have consummated the Initial Closing and the Outstanding Consent is subsequently obtained, the closing with respect to the Morro Bay Company Interest (the “Subsequent
Closing”) shall take place on the date and in the manner required for the Closing under Section 2.3 (the date of such Subsequent Closing, the “Subsequent Closing Date”), except that (i) the portion of
the Purchase Price payable at the Subsequent Closing shall be equal to the Morro Bay Purchase Price plus or minus the amounts calculated pursuant to Sections 2.2(b) and (c) (calculated using the Subsequent Closing Date in place of the Closing
Date, but including in such calculations only amounts attributable to the Morro Bay Project) and (ii) all representations and warranties made by Seller at the Subsequent Closing shall be deemed to be made solely with respect to the Morro Bay
Project and the Morro Bay Company Interest. For purposes of the Subsequent Closing, each reference to “the Closing” or “the Closing Date” in a provision hereof as such provision relates to the Morro Bay Company Interest (and the
Morro 

  

 48 

 
Bay Project) shall be deemed to be a reference to “the Subsequent Closing” or “the Subsequent Closing Date” respectively. 
 6.16 Bridgeport Dispute. It is recognized that as of the date hereof UBE has put the UBE Interests to Duke Bridgeport Energy
pursuant to Section 8.3(b) of the Bridgeport LLC Agreement, that Duke Bridgeport Energy owes to UBE the purchase price therefor when such price is determined in connection with the settlement or resolution of the Bridgeport Dispute, that Duke
Bridgeport Energy has the obligation to purchase the UBE Interests from UBE, and that the Purchase Price to be paid on the Closing Date reflects whether the Bridgeport Dispute is resolved prior to the Closing Date. If the Bridgeport Dispute is not
resolved prior to the Closing Date, then from and after the Closing Date Seller shall have the exclusive right, at its expense, to direct, control, settle and resolve the Bridgeport Dispute (including the right to agree with UBE upon a value of the
UBE Interest). Buyer shall be liable for, and shall pay or cause Duke Bridgeport Energy to pay to UBE any amount agreed upon by Seller and UBE for the value of the UBE Interest in connection with the settlement or resolution of the Bridgeport
Dispute (such amount, the “Bridgeport Resolution Amount”), provided, however, that (concurrently with such payment to UBE) Seller shall pay to Buyer, or Buyer shall pay to Seller, the amount by which the Bridgeport Resolution
Amount is greater or lesser than, respectively, the sum of (a) the Bridgeport 33 1/33% Purchase Price plus
(b) one third (1/3) of the Adjusted Net Working Capital with respect to Bridgeport Energy and NC Development as of Closing. 
 6.17 Connecticut Transfer Act. Buyer shall, at its sole cost and expense, (a) prepare the Form III and Environmental Condition Assessment Form required by the Connecticut Transfer Act for the purchase and
sale of the Company Interests in Duke Bridgeport Energy to occur at the Closing; (b) provide the completed Form III and Environmental Condition Assessment Form to Seller not less than 10 days prior to the Closing for Seller’s review and
approval; (c) execute said Form III as the “Transferee” and as the “Certifying Party” thereon on or before the Closing Date; (d) execute the Environmental Condition Assessment Form as the party submitting same;
(e) provide a bank check made payable to the Connecticut Department of Environmental Protection in the amount required for a Form III filing at the Closing; and (f) perform the obligations imposed upon it as the “Certifying
Party” on said Form III and by this Section 6.17. Seller shall, at its sole cost and expense (i) execute said Form III as the “Transferor” thereon; and (ii) file the duly executed and delivered Form III and duly
executed and delivered Environmental Condition Assessment Form with the Connecticut Department of Environmental Protection together with the appropriate filing fee and fee form within 10 days after the Closing. 
 6.18 Long Term Services Agreements. Seller may cause each Project Company party to a GE LTSA to terminate such GE LTSA
effective as of the Closing Date unless (a) Buyer provides written notice at least 10 Business Days prior to the Closing Date to Seller requesting that such Project Company not terminate such GE LTSA and (b) Buyer delivers to Seller,
contemporaneous with the notice described in the preceding clause (a), a written release with an effective date on or before the Closing Date fully discharging and releasing the guarantor under each Support Obligation issued with respect to such GE
LTSA on behalf of such Project Company and executed by the beneficiary of such Support Obligation. During the Interim Period, Buyer shall have the right to contact and have discussions with General Electric International, Inc. to discuss the GE
LTSAs.

 6.19 Tax Matters. Except as provided in Section 6.13 relating to
Transfer Taxes: 
 (a) With respect to any Tax return covering a taxable period ending on or before the Closing Date (a
“Pre-Closing Taxable Period”) that is required to be filed after the Closing Date with respect to a Project Company, (i) Seller shall cause such Tax return to be prepared in a manner consistent with practices followed in prior taxable
periods and in compliance with applicable Law except as required by change in Law or fact and shall deliver such Tax return as so prepared to Buyer not later than 15 days (30 days with respect to the partnership returns for Bridgeport Energy and NC
Development and 3 days with respect to any Property Tax return) prior to the due date (including extensions) for filing such Tax return for Buyer’s review and comments, (ii) with respect to any issue that could materially and adversely
affect Buyer or the applicable Project Company in a taxable period (or portion thereof) beginning after the Closing Date, Seller shall cooperate and consult with Buyer to finalize such Tax return, and (iii) thereafter, subject to Seller’s
payment to Buyer of such Tax in compliance with Section 6.19(b), Buyer shall cause such Tax return to be executed and duly and timely filed with the appropriate Taxing Authority and shall pay all Taxes shown as due and payable on such Tax
return. With respect to any Tax return covering a taxable period beginning on or before the Closing Date and ending after the Closing Date (a “Straddle Taxable Period”) that is required to be filed after the Closing Date with respect to a
Project Company, (i) Buyer shall cause such Tax return to be prepared (in a manner consistent with practices followed in prior taxable periods except as required by a change in Law or fact) and shall deliver a draft of such Tax return to Seller
for Seller’s review and approval at least 15 days prior to the due date (including extensions) for filing such Tax return, (ii) Seller and Buyer shall cooperate and consult with each other in order to finalize such Tax return, and
(iii) thereafter, subject to Seller’s payment to Buyer of any portion of such Tax in compliance with Section 6.19(b), Buyer shall cause such Tax return to be executed and duly and timely filed with the appropriate Taxing Authority and
shall pay all Taxes shown as due and payable on such Tax return. Notwithstanding the foregoing, with respect to Southwest Power Partners, ED Services and Griffith Energy, neither Seller nor Buyer shall be required by reason of this
Section 6.19(a) to prepare any Tax return which for the prior taxable period was prepared by a Person other than Seller. 
 (b) Subject to Section 10.1(b), Seller shall be responsible for and indemnify the Buyer Indemnified Parties against, and Seller shall be entitled to all refunds or credits of, any Tax with respect to a Project Company that is
attributable to a Pre-Closing Taxable Period or to that portion of a Straddle Taxable Period that ends on the Closing Date. Within 5 days prior to the due date for the payment of any such Tax, Seller shall pay to Buyer the amount of such Taxes, less
any prepaid Taxes. With respect to a Straddle Taxable Period, Seller and Buyer shall determine the Tax attributable to the portion of the Straddle Taxable Period that ends on the Closing Date by an interim closing of the books of the Project Company
as of the Closing Date, except for ad valorem or property Taxes (“Property Taxes”) and franchise Taxes based solely on capital which shall be prorated on a daily basis to the Closing Date. For this purpose, any franchise Tax paid or
payable with respect to the Project Company shall be allocated to the taxable period for which payment of the Tax provides the right to engage in business, regardless of the taxable period during which the income, operations, assets or capital
comprising the base of such Tax is measured. In determining whether a Property Tax is attributable to a Pre-Closing Taxable Period or a Straddle Taxable Period, any Property Tax that is based on the assessed value of any assets, property or other
rights as of any lien date or other specified valuation date 

  

 50 

 
shall be deemed a Property Tax attributable to the taxable period (whether a fiscal year or other tax year) specified on the relevant Property Tax bill that
is issued with respect to that lien date or other valuation date. Notwithstanding the foregoing, with respect to any Project Company in which Seller does not directly or indirectly own 100% of the Company Interests, the calculation of the amount of
Tax of such Project Company for which Seller is responsible or entitled to refunds or credits under this Section 6.19(b) shall be made by reference to Seller’s direct and indirect percentage ownership of such Project Company. 

(c) Subject to Section 10.1 (a), Buyer shall be responsible for and indemnify Seller against, and Buyer shall be entitled to all
refunds and credits of, all Taxes of the Project Companies that are attributable to a taxable period (or portion thereof) beginning after the Closing Date. 
 (d) With respect to any Tax for which Seller is responsible, Seller shall have the right, at its sole cost and expense, to initiate any
claim for refund and to control (in the case of a Pre-Closing Taxable Period) or participate in (in the case of a Straddle Taxable Period) the prosecution, settlement or compromise of any proceeding involving such Tax, including the determination of
the value of property for purposes of real and personal property ad valorem Taxes. Buyer shall (and shall cause the relevant Project Company to) take such action in connection with any such proceeding as Seller shall reasonably request from time to
time to implement the preceding sentence, including the selection of counsel and experts and the execution of powers of attorney. Notwithstanding the foregoing, Seller shall not settle any proceeding with respect to any issue that could materially
and adversely affect Buyer or the applicable Project Company in a taxable period (or portion thereof) beginning after the Closing Date without Buyer’s prior written consent, not to be unreasonably withheld. Buyer shall (and shall cause the
relevant Project Company to) give written notice to Seller of its receipt of any notice of any audit, examination, claim or assessment for any Tax for which Seller is responsible within 20 days after its receipt of such notice; failure to give any
such written notice within such 20-day period shall limit Seller’s indemnification obligation pursuant to this Agreement to the extent Seller is actually prejudiced by such failure. 
 (e) Seller shall grant to Buyer (or its designees) access at all reasonable times to all of the information, books and records relating
to the Project Companies within the possession of Seller (including workpapers and correspondence with Taxing Authorities), and shall afford Buyer (or its designees) the right (at Buyer’s expense) to take extracts therefrom and to make copies
thereof, to the extent reasonably necessary to permit Buyer (or its designees) to prepare Tax returns, respond to Tax audits and investigations, prosecute Tax protests, appeals and refund claims and to conduct negotiations with Taxing Authorities.
Buyer shall grant or cause the Project Companies to grant to Seller (or its designees) access at all reasonable times to all of the information, books and records relating to the Project Companies for Pre-Closing Taxable Periods or Straddle Taxable
Periods within the possession of Buyer (including workpapers and correspondence with Taxing Authorities) and to the employees of the Project Companies, and shall afford Seller (or its designees) the right (at Seller’s expense) to take extracts
therefrom and to make copies thereof, in each case to the extent reasonably necessary to permit Seller (or its designees) to prepare Tax returns, respond to Tax audits and investigations, prosecute Tax protests, appeals and refund claims and to
conduct negotiations with Taxing Authorities. After the Closing Date, Seller and Buyer will preserve all information, records or 

  

 51 

 
documents in their respective possessions relating to liabilities for Taxes of the Project Companies for Pre-Closing Taxable Periods or Straddle Taxable
Periods until six months after the expiration of any applicable statute of limitations (including extensions thereof) with respect to the assessment of such Taxes; provided, that neither Party shall dispose of any of the foregoing items without
first offering such items to the other Party. 
 (f) If after the Closing Buyer or a Project Company receives a refund or
utilizes a credit of any Tax of a Project Company attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date, Buyer shall pay to Seller within ten Business Days after such receipt or
utilization an amount equal to such refund received or credit utilized, together with any interest received or credited thereon. Buyer shall, and shall cause the Project Company to, use commercially reasonable efforts to obtain a refund or credit of
any Tax of the Project Company attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date or to mitigate, reduce or eliminate any such Tax that could be imposed for a Pre-Closing Taxable
Period or that portion of a Straddle Taxable Period ending on the Closing Date (including with respect to the transactions contemplated hereby). 
 (g) In the event that Seller initiates a claim for refund from a Taxing Authority with regard to any Tax of a Project Company attributable to a Pre-Closing Taxable Period or that portion of a Straddle Taxable Period
ending on the Closing Date, whether the initiation of such claim begins prior to or after the Closing, Seller shall have all rights to and interest in such refund. Buyer shall, upon request, provide Seller a limited power of attorney allowing Seller
to pursue such claim for refund with and collect such refund from such Taxing Authority. Notwithstanding the foregoing, Buyer shall have the right to participate at its own expense in any action with respect to such claim for refund, and Seller
shall not settle any such claim in a manner that could materially and adversely affect Buyer or the applicable Project Company in a taxable period (or portion thereof) beginning after the Closing Date without Buyer’s prior written consent, not
to be unreasonably withheld. If after the Closing Buyer or the Project Company receives a refund or utilizes a credit of any such Tax with regard to a claim so initiated by Seller, Buyer shall pay to Seller within ten Business Days after such
receipt or utilization an amount equal to such refund received or credit utilized, together with any interest received or credited thereon. 
 (h) In the event that Seller initiates a claim for refund from a third party who improperly withheld sales and use Tax, or withheld excessive sales and use Tax, with regard to a Project Company attributable to a
Pre-Closing Taxable Period or that portion of a Straddle Taxable Period ending on the Closing Date, whether the initiation of such claim begins prior to or after the Closing, Seller shall have all rights to and interest in such refund. Buyer shall,
upon request, provide Seller a limited power of attorney allowing Seller to pursue such claim for refund with and collect such refund from such third party. Notwithstanding the foregoing, (A) Seller shall not initiate any such claim for refund
from a third party without Buyer’s prior written consents, not to be unreasonably withheld, (B) Buyer shall be entitled to participate with Seller in any discussions with such third party and (C) Seller shall not settle any such claim
in a manner that could materially and adversely affect Buyer or the applicable Project Company in a taxable period (or portion thereof) beginning after the Closing Date without Buyer’s prior written consent, not to be unreasonably withheld. If
after the Closing Buyer or the Project Company 

  

 52 

 
receives a refund of any such Tax with regard to a claim so initiated by Seller, Buyer shall pay to Seller within ten Business Days after such receipt an
amount equal to such refund received, together with any interest received or credited thereon. 
 (i) To the extent that the
provisions of Article X are inconsistent with or conflict with the provisions of this Section 6.19, the provisions of this Section 6.19 shall control. 
 (j) Seller will use commercially reasonable efforts to cause each of Bridgeport Energy, NC Development and Southwest Power Partners to
have in effect for its taxable year in which the Closing Date occurs an election under section 754 of the Code. 
 6.20 Affiliate
Contracts. From and after the date hereof, Buyer and Seller shall use commercially reasonable efforts to obtain the written consent from each party (other than Seller and its Affiliates) (each a
“Counterparty”) to each Affiliate Contract that is not a Terminated Contract to the assignment and assumption or novation of such Affiliate Contract by each Assignor to each Assignee identified on Schedule 1.1-AC as
contemplated by Section 2.4(b) to occur at Closing, provided, however, that with respect to those Affiliate Contracts not marked with an asterisk on Schedule 1.1-AC, the failure to obtain such consent shall not delay or prevent Closing,
and any obligation to seek such consent by Buyer or Seller shall (except with respect to any of the Affiliate Contracts listed as items 4, 5 and 7 on Schedule 1.1-AC) terminate as of the Closing. Without limiting the foregoing, Buyer’s
efforts shall include offering to replace any credit support posted or maintained by Seller or a Non-Company Affiliate in favor of any Counterparty to any Affiliate Contract in accordance with the requirements of Section 6.5, and in the case of
Affiliate Contracts with respect to which none of Seller or any Non-Company Affiliate has posted or maintains any credit support, Buyer shall comply with all commercially reasonable requests from any Counterparty under such Affiliate Contracts to
post or maintain credit support as security for the performance of the obligations of the Assignee thereof. With respect to any of the Affiliate Contracts listed as items 4, 5 and 7 on Schedule 1.1-AC which cannot be assigned and assumed or
novated at the Closing because of the failure to obtain such consent of the Counterparty, (a) Seller and Buyer shall, to the extent permissible under applicable Laws and under the terms of such Affiliate Contract, cause the respective Assignor
and Assignee identified on Schedule 1.1-AC to enter into arrangements intended to put such Assignor and Assignee in substantially the same economic position as if such Affiliate Contract were assigned and assumed or novated from the Closing
until such Affiliate Contract expires by its terms and (b) if such arrangements are not entered into, Seller shall indemnify Buyer against all losses and liabilities (including Non-reimbursable Damages) arising out of the failure of any such
Affiliate Contract to be assigned and assumed or of such arrangements to be entered into; provided, however, that Seller’s liability under this clause (b) with respect to the Affiliate Contract listed as item 7 on Schedule 1.1-AC
shall not exceed $10 million. 
 6.21 Further Assurances. Subject to the terms and conditions of this Agreement,
at any time or from time to time after the Closing, at any Party’s request and without further consideration, the other Party shall execute and deliver to such Party such other instruments of sale, transfer, conveyance, assignment and
confirmation, provide such materials and information and take such other actions as such Party may reasonably request in order to consummate the transactions contemplated by this Agreement. 
  

 53 

 6.22 Moss Landing Toll. (a) If (i) an Affiliate of Seller (or, at
the Seller’s request, Buyer or a Project Company designated by Buyer) enters into the Moss Landing Toll on or prior to the 90th day following the Closing Date and (ii) the Counterparty to such Moss Landing Toll has approved on or prior to
November 30, 2006 the transfer thereof to Buyer or a Project Company designated by Buyer (or if no such approval is required), then Seller shall promptly provide notice to Buyer which shall (A) state that the items set forth in
Section 6.22(a)(i)and (ii) have been satisfied, (B) attach a copy of the Moss Landing Toll, and (C) set forth the amount of the Moss Landing Toll Purchase Price Adjustment (which may be positive, negative or zero). Seller shall
use commercially reasonable efforts to cause the Moss Landing Toll to be transferred, if applicable, to Buyer or such Project Company within 5 Business Days following such notice. Concurrently with such transfer (or, if requested by Seller,
concurrently with the entry by Buyer or a Project Company designated by Buyer into the Moss Landing Toll directly), Buyer shall pay to Seller or its designee (by wire transfer of immediately available funds to an account designated by Seller) an
amount equal to the sum of the Moss Landing Toll Purchase Price and the Moss Landing Toll Purchase Price Adjustment (which may be positive, negative or zero). 
 (b) If Buyer fails to maintain a Minimum Net Worth of at least $440 million at all times during the period from the Closing through
December 15, 2006 (or, if earlier, the date on which the Moss Landing Toll Purchase Price (as adjusted by the Moss Landing Toll Purchase Price Adjustment) has been paid by Buyer to Seller pursuant to Section 6.22(a)), then Buyer shall pay
to an escrow agent designated by Seller an amount equal to the Moss Landing Toll Purchase Price. The monies held by such escrow agent shall be applied to the payment of the Moss Landing Toll Purchase Price (as adjusted by the Moss Landing Toll
Purchase Price Adjustment) at the times set forth in Section 6.22(a) for the payment of such amounts by Buyer. If the conditions set forth in Section 6.22(a)(i) and (ii) above have not been satisfied on or before November 30,
2006, then such funds on deposit with the escrow agent shall be returned to Buyer. 
 (c) During the period from the date of
this Agreement through the earlier to occur of (i) the assignment of the Moss Landing Toll to Buyer or a Project Company designated by Buyer and (ii) November 30, 2006, Buyer and Seller agree to use commercially reasonable efforts to
enter into additional agreements or to take such further actions as may be reasonably necessary to implement the items set forth in Section 6.22, including (A) Buyer or such Project Company posting (effective as of the transfer of the Moss
Landing Toll to Buyer or such Project Company) a guaranty, letter of credit or other credit support in accordance with the terms of the Moss Landing Toll to the Counterparty under the Moss Landing Toll, (B) Buyer effecting the full and
unconditional release of Seller or its Affiliates from any credit support provided by or on behalf of Seller and its Affiliates with respect to the Moss Landing Toll, and (C) Buyer cooperating with Seller, its Affiliates and the Counterparty to
the Moss Landing Toll to cause the assignment of such Toll to Buyer or such Project Company. 
 (d) In connection with the
Moss Landing Toll, Seller agrees (a) to use commercially reasonably efforts to include in the Moss Landing Toll (i) ML Other Terms that are consistent with the corresponding terms described in the Moss Landing RFP; provided that the ML
Fixed Terms shall not be changed in any material adverse respect from those corresponding terms set forth in the Moss Landing RFP without the prior written consent of Buyer, which consent shall 

  

 54 

 
not be unreasonably withheld, conditioned or delayed and (ii) gas and power scheduling procedures that are commercially reasonable in light of the
operating characteristics for the Moss Landing Project, (b) to use commercially reasonable efforts to minimize the amount of credit support that Buyer will have to provide in support of its obligations under the Moss Landing Toll and
(c) not to agree to any requirement that Buyer provide a Letter of Credit in excess of $100 million without Buyer’s consent, which may be withheld in its sole, reasonable discretion. If Buyer withholds its consent with respect to any
changes to the ML Fixed Terms, Buyer shall not enter into a transaction with respect to the Moss Landing Project on terms that are similar to the Moss Landing Toll proposed by Seller for a period of eighteen months following the date on which Buyer
withheld such consent. 
 (e) During the period from the date of this Agreement through November 30, 2006, neither Buyer
nor any of its Affiliates shall enter into any agreements or negotiations with any potential Counterparty to the Moss Landing Toll that is engaged in discussions with respect to the Moss Landing Toll with Seller or its Affiliates to the extent such
agreements or negotiations relate to sales of all or any portion of the energy, capacity or other ancillary services with respect to Unit 6 and/or Unit 7 of the Moss Landing Project. 
 6.23 Monthly Operating Report. During the Interim Period, on or prior to 30 Business Days following the end of each calendar

Working Capital (as of the closing of the transactions contemplated by such offer) of Southwest Power Partners, Griffith Energy and ED Services and upon substantially similar terms and conditions as those set forth in this Agreement. Buyer shall
promptly provide Seller with updates on its discussions with PPL regarding such purchase. 
 6.25 DEGM

by causing DEGM to transfer the Company Interests of DE Mulberry, DE Mohave and Duke Bridgeport Energy to DEGM Holding Subsidiary. 
 6.26 DENA Restructuring. Notwithstanding anything to the contrary in this Agreement, Seller may at any time prior to Closing at its option effect the DENA Restructuring and, promptly following the DENA
Restructuring, Seller, shall deliver to Buyer a new Schedule 3.4 reflecting the DENA Restructuring and a supplement to Schedule 4.13 reflecting any changes to the Charter Documents of the Parent Companies and/or the Project Companies
resulting from the DENA Restructuring. From and after the date of the delivery of such revised or replacement Schedules, all references in this Agreement to Schedule 3.4 or Schedule 4.13 shall be deemed to be references to such
replacement Schedule 3.4 and revised Schedule 4.13, as applicable. 
  

 55 

 6.27 Seller Creditworthiness. If Seller fails to maintain a Minimum Net Worth
of at least $700 million at any time from the Closing until the five year anniversary of the Closing or at least $100 million thereafter, then Seller shall cause one of its Affiliates with a Minimum Net Worth of at least such amount during such
relevant time period to guarantee to Buyer, in a form and substance reasonably satisfactory to Buyer, the obligations of Seller under Section 10.1 of this Agreement (it being agreed that Seller may, from time to time, substitute a different
Affiliate with such applicable Minimum Net Worth for the Affiliate then guaranteeing such obligations and Buyer shall promptly release such Affiliate then guaranteeing such obligations). 
 6.28 Letter of Credit. On or prior to January 11, 2006, Buyer shall provide to Seller (i) $75,000,000 of cash to be
held by Seller as collateral to secure Buyer’s obligations under Section 9.3 or (ii) an irrevocable, standby letter of credit with a face amount equal to $75,000,000 from a commercial bank with ratings of at least “A-” by
Standard & Poor’s Ratings Group ( a division of McGraw Hill, Inc.) and at least “A3” by Moody’s Investor Services, Inc. which shall be in form and substance reasonably satisfactory to Seller and which shall permit Seller
to draw upon such letter of credit upon a certification by Seller to such bank that the amount of the requested draw is the amount due from Buyer to Seller pursuant to Section 9.3.

 57 

 ARTICLE IX 
 TERMINATION 
 9.1 Termination. This Agreement may be terminated, and the transactions
contemplated hereby may be abandoned, as follows: 
 (a) at any time before the Closing, by Seller or Buyer, by written notice
to the other, in the event that any Law or final order restrains, enjoins or otherwise prohibits or makes illegal the transactions contemplated pursuant to this Agreement; 
 (b) at any time before the Closing, by Seller or Buyer, by notice to the other, if the other has materially breached its obligations
hereunder and such breach (other than a breach of Buyer’s obligation to pay the Purchase Price in accordance with the terms of Article II) has not been cured within 30 days following written notification thereof; provided, however, that
if, at the end of such 30 day period, the breaching Party is endeavoring in good faith, and proceeding diligently, to cure such breach, the breaching Party shall have an additional 30 days in which to effect such cure; 
 (c) at any time before the Closing, by Buyer or Seller, by notice to the other, on or after May 31, 2006; 
 (d) by Buyer or Seller pursuant to Section 6.11 or 6.12, by notice to the other party in accordance with such Sections; 

(e) by Seller, by written notice to the other, if Buyer has breached its obligation under Section 6.28 and such breach has not
been cured within one Business Day; or 
 (f) by mutual written consent of Buyer and Seller. 
 9.2 Effect of Termination. If this Agreement is validly terminated pursuant to Section 9.1, there will be no liability
or obligation on the part of Seller or Buyer (or any of their respective Representatives or Affiliates), provided that (a) Sections 6.2(b), 9.2, 10.5(a), 10.5(b), 11.3, 11.4, 11.12 and 11.3 will survive any such termination and
(b) each Party shall continue to be liable for any willful breach of this Agreement by it occurring prior to such termination. 
 9.3 Break-up Fee. (a) If this Agreement is terminated pursuant to Section 9.1(b), then, in lieu of all other Claims and remedies that might otherwise be available with respect thereto, including
elsewhere hereunder and notwithstanding any other provision of this Agreement: 
 (i) if Buyer has breached its obligation to
pay the Purchase Price pursuant to Sections 2.2 and 2.5 or its obligations under Section 6.1(a), 6.1(c) or 6.28 and, in the case of Section 6.28, such breach has not been cured within one Business Day, then Buyer shall pay to Seller, by
wire transfer of immediately available funds within three Business Days following the date of termination, as liquidated damages, 10% of the Base Purchase Price; 
  

 58 

 (ii) if Seller has breached its obligations to sell the Company Interests to Buyer
pursuant to Sections 2.1 and 2.4 or its obligations under Section 6.1(a) or 6.1(c), then Seller shall pay Buyer, by wire transfer of immediately available funds within three Business Days following the date of termination, as liquidated
damages, 10% of the Base Purchase Price; or 
 (iii) if either Buyer or Seller has materially breached any representation,
warranty, covenant, agreement or obligation hereunder (other than those referred to in Sections 9.3(a)(i) and 9.3(a)(ii)), then the breaching Party shall pay to the other, by wire transfer of immediately available funds within three Business Days
following the date of termination, as liquidated damages, the terminating Party’s actual and reasonable out-of-pocket fees (including reasonable attorney’s fees and regulatory filing fees) and expenses incurred in connection with this
Agreement, subject to a maximum of $4,000,000. 
 (b) The provision for payment of liquidated damages in this
Section 9.3 has been included because, in the event of a breach by Buyer or Seller, as the case may be, the actual damages to be incurred by any Party can reasonably be expected to approximate the amount of liquidated damages called for herein
and because the actual amount of such damages would be difficult if not impossible to measure accurately. 
 ARTICLE X

 ARBITRATION 
 10.1 Indemnification. (a) Subject to
Section 10.2, from and after Closing, Seller shall indemnify, defend and hold harmless Buyer, each of the Project Companies, and their respective partners, members, officers, employees, Affiliates and Representatives (collectively, the

however, that no Party may make or bring a Claim for liability with respect to (i) any representations or warranties contained in Articles III, IV or V (other than those representations and warranties contained in Section 3.2
(Authority), 3.4 (Capitalization), 4.1 (Organization), 4.3 (Capitalization) and 4.6 (Subsidiaries) (collectively, the “Title and Authority Representations”)) or any covenants, agreements or obligations in Sections 6.3 or 6.9,

 (c) Seller shall have no liability for breaches of representations and warranties, in this Agreement (other than a breach of a
representation or warranty contained in Section 4.11) until the aggregate amount of all Losses incurred by Buyer equals or exceeds 1.5% of the Base Purchase Price (the “Deductible Amount”), in which event Seller shall be
liable for Losses only to the extent they are in excess of the Deductible Amount (except as set forth below); 
 (d) in no
event shall Seller’s aggregate liability (i) arising out of or relating to this Agreement, whether relating to breach of representation and warranty, covenant, agreement or obligation in this Agreement and whether based on contract, tort,
strict liability, other Laws or otherwise (except as set forth in Section 10.2(j) below), exceed 10% of the Base Purchase Price, except as set forth in clause (ii) below; and (ii) arising out of or relating to any breach of a Title or
Authority Representation, a breach of a representation or warranty contained in Section 4.11 

  

 60 

 
or a breach of Section 6.19 (together with the aggregate liability pursuant to clause (i) above) exceed 100% of the Base Purchase Price;

 (e) Seller shall have no liability for any breach of a representation, warranty, covenant, agreement or obligation in this
Agreement by Seller (i) of which Buyer had knowledge prior to the date hereof or (ii) (x) of which Buyer did not have knowledge prior to the date hereof but of which Buyer had knowledge prior to the Closing Date and (y) where due
to such breach Buyer’s conditions to closing in Article VII were not met (and for purposes of this Section 10.2(e), the documents disclosed to Buyer or its Representatives in the course of its due diligence, and their contents, are deemed
to be known to Buyer); provided that this provision shall not apply to any willful breaches of a representation, warranty, covenant, agreement or obligation; 
 (f) Notwithstanding anything to the contrary herein, the Parties agree that each representation or warranty of Seller made herein shall
be limited solely to Seller’s Knowledge as such representation or warranty relates to any of the Jointly Owned Project Companies, and the requirement of any covenant, obligation or agreement of Seller herein (other than those set forth in
Article II) relating to any of the Jointly Owned Project Companies shall be limited solely to a requirement to use commercially reasonable efforts to perform such covenant, obligation or agreement; 
 (g) a Party must give written notice to the other Party within a reasonable period of time after becoming aware of any breach by such
other Party of any representation, warranty, covenant, agreement or obligation in this Agreement; 
 (h) the Parties shall
have a duty to mitigate any Loss in connection with this Agreement; 
 (i) Seller shall have no liability for any Losses that
represent the cost of repairs, replacements or improvements which enhance the value of the repaired, replaced or improved asset above its value on the Closing Date or which represent the cost of repair or replacement exceeding the lowest reasonable
cost of repair or replacement; 
 (j) Notwithstanding anything herein to the contrary, the limitations, covenants, agreements
and obligations set forth in this Section 10.2 shall not apply to Seller’s indemnification obligations pursuant to Section 10.1(a)(iii). 
 (k) Upon and after the Closing, none of the Project Companies shall have any liability or obligation to indemnify, save or hold harmless or otherwise pay, reimburse or make any Seller Indemnified Party whole for or on
account of any indemnification claim made by the Seller or any of its Affiliates or Representatives for any breach of any representation, warranty, covenant or agreement of the Seller, and the Seller shall have no right of contribution against any
Project Company; other than, in all cases under this clause (k), with respect to any Contracts between a Project Company, on the one hand, and Seller or any of its Affiliates, on the other. 
 (1) The Losses suffered by any Indemnified Party shall be calculated after giving effect to any amounts covered by third parties,
including insurance proceeds, in each case net of costs and expenses of such recoveries and net of any associated tax benefits to Buyer or 

  

 61 

 
any Project Company (it being understood and agreed that the Indemnified Parties shall use their commercially reasonable efforts to seek insurance recoveries
in respect of Losses to be indemnified hereunder). In the event any insurance proceeds or other recoveries from third parties are actually realized (in each case calculated net of costs and expenses of such recoveries) by an Indemnified Party
subsequent to the receipt by such Indemnified Party of an indemnification payment hereunder in respect of the claims to which such insurance proceedings or third party recoveries relate, appropriate refunds shall be made promptly to the indemnifying
party regarding the amount of such indemnification payment. 
 10.3 Indirect Claims. From and after the Closing,
Buyer agrees to release, indemnify and hold harmless Seller, its Affiliates and the officers, directors and employees of the Project Companies (acting in their capacity as such) from and against any Claims for controlling stockholder liability or
breach of any fiduciary duty relating to any pre-Closing actions or failures to act (including negligence or gross negligence) by Seller or any of its Affiliates in connection with the business of the Project Companies prior to the Closing.

 10.4 Waiver of Other Representations. (a) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, IT
IS THE EXPLICIT INTENT OF EACH PARTY HERETO, AND THE PARTIES HEREBY AGREE, THAT NONE OF SELLER OR ANY OF ITS AFFILIATES OR REPRESENTATIVES HAS MADE OR IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, WRITTEN OR ORAL,
INCLUDING ANY IMPLIED REPRESENTATION OR WARRANTY AS TO THE CONDITION, MERCHANTABILITY, USAGE, SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE WITH RESPECT TO THE COMPANY INTERESTS, THE PROJECT COMPANIES OR ANY OF THE PURCHASED ASSETS, OR ANY PART
THEREOF, EXCEPT THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN ARTICLES III AND IV. IN PARTICULAR, AND WITHOUT IN ANY WAY LIMITING THE FOREGOING, (I) SELLER MAKES NO REPRESENTATION OR WARRANTY REGARDING ANY ENVIRONMENTAL MATTERS EXCEPT AS
EXPRESSLY SET FORTH IN SECTIONS 4.15 AND 4.16 AND (II) SELLER MAKES NO REPRESENTATION OR WARRANTY TO BUYER WITH RESPECT TO ANY FINANCIAL PROJECTIONS OR FORECASTS RELATING TO THE PROJECT COMPANIES OR THE PURCHASED ASSETS. 
 (b) EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THE REPRESENTATIONS AND WARRANTIES IN ARTICLES III AND IV, SELLER’S INTERESTS IN THE
PROJECT COMPANIES ARE BEING TRANSFERRED THROUGH THE SALE OF THE COMPANY INTERESTS “AS IS, WHERE IS, WITH ALL FAULTS,” AND SELLER EXPRESSLY DISCLAIMS ANY REPRESENTATIONS OR WARRANTIES OF ANY KIND OR NATURE, EXPRESS OR IMPLIED, AS TO THE
CONDITION, VALUE OR QUALITY OF THE PROJECT COMPANIES AND THEIR ASSETS OR THE PROSPECTS (FINANCIAL OR OTHERWISE), RISKS AND OTHER INCIDENTS OF THE PROJECT COMPANIES AND THEIR ASSETS. 
 10.5 Waiver of Remedies. (a) The Parties hereby agree that, except with respect to Claims for fraud (but not
constructive fraud), neither Party shall have any liability, and neither Party shall make any Claim, for any Loss or other matter, under, relating to or arising out of this 

  

 62 

 
Agreement or any other document, agreement, certificate or other matter delivered pursuant hereto, whether based on contract, tort, strict liability, other
Laws or otherwise, except as provided in Articles IX and X. 
 (b) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE
CONTRARY, NO PARTY SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES OR LOST PROFITS, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM THE OTHER
PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT (“Non reimbursable Damages”), PROVIDED THAT ANY AMOUNTS PAYABLE TO THIRD PARTIES PURSUANT A THIRD-PARTY CLAIM (OTHER THAN A CLAIM FOR
CONSEQUENTIAL DAMAGES ARISING UNDER A CONTRACT PROVISION AGREED TO BY THE INDEMNIFIED PARTY THAT DOES NOT NEGATE CONSEQUENTIAL DAMAGES) SHALL NOT BE DEEMED NON-REIMBURSABLE DAMAGES. 
 (c) Notwithstanding anything in this Agreement to the contrary, no Representative or Affiliate of Seller shall have any liability to
Buyer or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of Seller in this Agreement and, except as set forth in the commitment letter executed by the Funds as of the date hereof with
respect to obligations relating to Section 9.3, no Representative or Affiliate of Buyer shall have any liability to Seller or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of Buyer
in this Agreement. 
 10.6 Arbitration. (a) Any and all disputes between the Parties arising out of or
relating to this Agreement (a “Dispute”) must be resolved through the use of binding arbitration using three arbitrators, selected in accordance with the Commercial Arbitration Rules of the American Arbitration Association
(“AAA”), as supplemented to the extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United States Code). If there is any inconsistency between this Section 10.6
and the Commercial Arbitration Rules or the Federal Arbitration Act, the terms of this Section 10.6 will control the rights and obligations of the Parties. If there is more than one Arbitrable Dispute that involves the same facts and parties as
the facts and parties with respect to which an arbitration has been initiated pursuant to this Agreement, such Disputes shall be consolidated into the first arbitration initiated pursuant to this Agreement. No other arbitration shall be consolidated
with any arbitration initiated pursuant to this Agreement without the agreement of the Parties or parties thereto. 
 (b)
Arbitration must be initiated within the time limits specified in Section 10.2(a) or, if no time limit is specified, within the time period allowed by the applicable statute of limitations. Arbitration may be initiated by either Seller or Buyer
(“Claimant”) serving written notice on the other Party (“Respondent”) that Claimant elects to refer the Dispute to binding arbitration (the “Arbitrable Dispute”). 
 (c) Claimant’s notice initiating binding arbitration must describe in reasonable detail the nature of the Arbitrable Dispute and the
facts and circumstances relating thereto and identify the arbitrator Claimant has appointed. Respondent shall respond to Claimant within 60 

  

 63 

 
days after receipt of Claimant’s notice, identifying the arbitrator Respondent has appointed. If Respondent fails for any reason to name an arbitrator
within the 60 day period, the arbitrator for Respondent’s account shall be selected by the AAA office in New York, New York, with due regard for the selection criteria set forth below and input from the Parties. The two arbitrators so chosen
shall select a third arbitrator within 30 days after the second arbitrator has been appointed. If the two arbitrators are unable to agree on a third arbitrator within 90 days from initiation of arbitration, then a third arbitrator shall be selected
by the AAA office in New York, New York, with due regard for the selection criteria set forth below and input from the Parties and other arbitrators. 
 (d) The AAA shall select the third arbitrator not later than 120 days from initiation of arbitration. In the event AAA should fail to select the third arbitrator within 120 days from initiation of arbitration, then
either Party may petition the Chief United States District Judge in New York County, New York to select the third arbitrator. Due regard shall be given to the selection criteria set forth below and input from the Parties and other arbitrators.

 (e) Subject to the arbitrators’ award of costs to the prevailing party, Claimant shall pay the compensation and
expenses of the arbitrator named by or for it, Respondent shall pay the compensation and expenses of the arbitrator named by or for it, and Claimant and Respondent shall each pay one-half of the compensation and expenses of the third arbitrator. All
arbitrators must be neutral parties who have never been officers, directors or employees of, or otherwise affiliated in any material respect within the preceding five years with, the Parties or any of their Affiliates. Each of the three arbitrators
must have not less than seven years experience as an attorney or accountant handling complex business transactions and have formal training in dispute resolution. 
 (f) The hearing will be conducted in New York, New York and commence within 60 days after the selection of the third arbitrator. The
Parties and the arbitrators should proceed diligently and in good faith in order that the award may be made as promptly as possible. The arbitrators shall determine the Arbitrable Disputes of the Parties and render a final award in accordance with
the choice of Law set forth in this Agreement. The arbitrators shall render their decision within 60 days following completion of the hearing. The arbitrators’ decision shall be in writing and set forth the reasons for the award and shall
include an award of costs to the prevailing Party (or an allocation of such costs between the Parties based upon the extent to which each prevails), including reasonable attorneys’ fees and disbursements and the fees and expenses of the
arbitrators. All statutes of limitations and defenses based upon passage of time applicable to any Arbitrable Dispute (including any counterclaim or setoff) shall be interrupted by the filing of the arbitration and suspended while the arbitration is
pending. The terms of this Section 10.6 shall not create nor limit any obligations of a Party hereunder to defend, indemnify or hold harmless another Party against Claims or Losses. In order to prevent irreparable harm, the arbitrators shall
have the power to grant temporary or permanent injunctive or other equitable relief. 
 (g) A Party may, notwithstanding
anything in this Agreement to the contrary, seek temporary injunctive relief from any court of competent jurisdiction; provided, however, that the Party seeking such relief shall (if arbitration has not already been commenced) 

  

 64 

 
simultaneously commence arbitration. Such court-ordered relief shall not continue more than ten days after the appointment of the arbitrators and in no event
for longer than 60 days. 
 (h) Except as provided in the Federal Arbitration Act, the decision of the arbitrators will be
binding on and non-appealable by the Parties. Each Party agrees that any arbitration award against it may be enforced in any court of competent jurisdiction and that any Party may authorize any such court to enter judgment on the arbitrators’
decisions. In no circumstances shall the arbitrators grant or award Non-reimbursable Damages. 
 10.7 Procedure
with Respect to Third-Party Claims. (a) If any Party (or as to Buyer after Closing, any Project Company) becomes subject to a pending or threatened Claim of a third party and such Party (the “Claiming
Party”) believes it has a claim against the other Party (the “Responding Party”) as a result, then the Claiming Party shall notify the Responding Party in writing of the basis for such Claim setting forth the
nature of the Claim in reasonable detail. The failure of the Claiming Party to so notify the Responding Party shall not relieve the Responding Party of liability hereunder except to the extent that the defense of such Claim is prejudiced by the
failure to give such notice. 
 (b) If any proceeding is brought by a third party against a Claiming Party and the Claiming
Party gives notice to the Responding Party pursuant to Section 10.7, the Responding Party shall be entitled to participate in such proceeding and, to the extent that it wishes, to assume the defense of such proceeding, if (i) the
Responding Party provides written notice to the Claiming Party that the Responding Party intends to undertake such defense, (ii) the Responding Party conducts the defense of the third-party Claim actively and diligently with counsel reasonably
satisfactory to the Claiming Party and (iii) if the Responding Party is a party to the proceeding, the Responding Party or the Claiming Party has not determined in good faith that joint representation would be inappropriate because of a
conflict in interest. The Claiming Party shall, in its sole discretion, have the right to employ separate counsel (who may be selected by the Claiming Party in its sole discretion) in any such action and to participate in the defense thereof, and
the fees and expenses of such counsel shall be paid by such Claiming Party. The Claiming Party shall fully cooperate with the Responding Party and its counsel in the defense or compromise of such Claim. If the Responding Party assumes the defense of
a proceeding, no compromise or settlement of such Claims may be effected by the Responding Party without the Claiming Party’s consent unless (A) there is no finding or admission of any violation of Law or any violation of the rights of any
Person and no effect on any other Claims that may be made against the Claiming Party and (B) the sole relief provided is monetary damages that are paid in full by the Responding Party. 
 (c) If (i) notice is given to the Responding Party of the commencement of any third-party legal proceeding and the Responding Party
does not, within 30 days after the Claiming Party’s notice is given, give notice to the Claiming Party of its election to assume the defense of such legal proceeding, (ii) any of the conditions set forth in clauses (i) through
(iii) of Section 10.7(b) above become unsatisfied or (iii) a Claiming Party determines in good faith that there is a reasonable probability that a legal proceeding may adversely affect it other than as a result of monetary damages for
which it would be entitled to indemnification from the Responding Party under this Agreement, then the Claiming Party shall (upon notice to the Responding Party) have the right to undertake the defense, compromise or settlement of such 

  

 65 

 
claim; provided, however, that the Responding Party shall reimburse the Claiming Party for the costs of defending against such third-party claim
(including reasonable attorneys’ fees and expenses) and shall remain otherwise responsible for any liability with respect to amounts arising from or related to such third-party claim, in both cases to the extent it is ultimately determined that
such Responding Party is liable with respect to such third-party claim for a breach under this Agreement. The Responding Party may elect to participate in such legal proceedings, negotiations or defense at any time at its own expense. 
 10.8 Access to Information. After the Closing Date, Seller and Buyer shall grant each other (or their respective designees),
and Buyer shall cause the Project Companies to grant to Seller (or its designees), access at all reasonable times to all of the information, books and records relating to the Project Companies in its possession, and shall afford such party the right
(at such party’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to implement the provisions of, or to investigate or defend any claims between the Parties arising under, this Agreement.

 11.4 Disclosure. Seller may, at its option, include in the Schedules items that are not material in order to avoid any
misunderstanding, and any such inclusion, or any references to dollar amounts, shall not be deemed to be an acknowledgment or representation that such items are material, to establish any standard of materiality or to define further the meaning of
such terms for purposes of this Agreement. Information disclosed in any Schedule shall constitute a disclosure for purposes of all other Schedules notwithstanding the lack of specific cross-reference thereto, to the extent the applicability of such
disclosure to such other Schedule is reasonably apparent on its face. The Parties shall promptly notify each other of (a) the occurrence, or failure to occur, of any event, which occurrence or failure has caused any representation or warranty
of such Party contained in this Agreement or in any exhibit, schedule, certificate, document or written instrument attached hereto to be untrue or inaccurate, (b) any failure of such Party to comply with, perform or satisfy, in any respect, any

except as set forth in Section 10.2(e), shall not affect any Party’s right with respect to indemnification hereunder. 
 11.5
Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or
on behalf of the Party waiving such term or condition. No waiver by any Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this
Agreement on any future occasion. All remedies, either under this Agreement or by Law or otherwise afforded, will be cumulative and not alternative. 
 11.6 Amendment. This Agreement may be amended, supplemented or modified only by a written instrument duly executed by or on behalf of each Party. 
  

 67 

 11.7 No Third Party Beneficiary. Except for the provisions of
Section 6.2(b), 6.5(e)(ii) and (h), the third sentence of Section 6.7(b), 10.1 (a) and (b) and 10.3 (which are intended for the benefit of the Persons identified therein), the terms and provisions of this Agreement are intended
solely for the benefit of the Parties 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, including, without limitation, any Continued
Employee, any beneficiary or dependents thereof, or any collective bargaining representative thereof. 
 11.8 Assignment; Binding
Effect. Buyer may assign its rights and obligations hereunder to any Affiliate or Affiliates, or to Buyer’s lenders for collateral security purposes, but such assignment shall not release Buyer from its obligations
hereunder. Except as provided in the preceding sentence, neither this Agreement nor any right, interest or obligation hereunder may be assigned by any Party without the prior written consent of the other Party, and any attempt to do so will be void,
except for assignments and transfers by operation of Law. Subject to this Section 11.8, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties and their respective successors and permitted assigns.

not define or limit the provisions hereof. 
 11.10 Invalid Provisions. If any provision of this Agreement is
held to be illegal, invalid or unenforceable under any present or future Law, and if the rights or obligations of any Party under this Agreement will not be materially and adversely affected thereby, such provision will be fully severable, this
Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the
illegal, invalid or unenforceable provision or by its severance herefrom and in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as
similar in terms to such illegal, invalid or unenforceable provision as may be possible. 
 11.11 Counterparts;
Facsimile. This Agreement may be executed in any number of counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. Any facsimile copies hereof or signature
